Gallstone recurrence after successful shock wave therapy: the magnitude of the problem and the predictive factors.

OBJECTIVE: Reports concerning long term recurrence of gallstones after successful extracorporeal shock wave lithotripsy (ESWL) show a high probability of stone recurrence. There is still discussion on the factors influencing stone recurrence. In this study we wanted to evaluate the long term recurrence of gallstones after stone clearance with ESWL and oral bile acids, and to assess possible risk and preventive factors of stone recurrence. METHODS: A total of 322 consecutive patients with stone clearance between December 1988 and December 1995 were included. All patients were contacted for ultrasonography and were interviewed for additional information on daily intake of aspirin, NSAIDs, cholesterol lowering medication, estrogen therapy, and biliary pain during follow-up. RESULTS: A total of 187 patients were still stone-free after a mean follow-up of 35 months (range: 3-89 months); 135 patients had recurrence. There was a significant association between stone recurrence and estrogen intake (p = 0.04), number of lithotripsy sessions (p = 0.0007), time until stone disappearance (p = 0.0003), and biliary pain (p < 0.0001). There was no difference in recurrence rate between solitary and multiple stones. CONCLUSIONS: Long-term recurrence of gallstones after lithotripsy is high: < or = 69% after 6 yr. We found a significant association of stone recurrence with estrogen intake, number of lithotripsy sessions, and time until stone disappearance. Intake of aspirin or NSAIDs was not associated with decreased stone recurrence. Of the patients with recurrent stones, 57% had biliary pain.

Risk of recurrence of occupational back pain over three year follow up.

A random sample including 2342 cases representative of all occupational back injuries in Quebec (1981) was followed up prospectively over three years to assess the recurrence rate of back problems (lumbar, thoracic, and cervical). Each medical and accident report was reviewed to obtain the site of symptoms and occupation. Age, sex, industrial sector, and number of episodes of absence from work were abstracted from the computerised Quebec Compensation Board files. The recurrence rate was 20.0% at one year follow up and 36.3% at three years. A multivariate analysis using a Poisson regression, was performed to model the risk of recurrence over time. Men had a higher chance of recurrence (risk ratio = 1.85, 95% CI = 1.50-2.27) but among recurrent cases, the average total number of episodes was comparable between men and women. Age showed a protective effect on the probability of recurrence (10 years: RR = 0.93, 95% CI = 0.88-0.98) due to the lower recurrence rate in the 45-64 year old group (31.8%). Cervical and lumbar symptoms had identical recurrence profiles whereas thoracic symptoms had a significantly lower recurrence rate. Drivers had the highest recurrence rate (42.1%) and nurses had the highest average number of recurrences (2.03) among recurrent cases. Both occupations had statistically significant excesses after controlling for the other variables.

Acyclovir vs isoprinosine (immunovir) for suppression of recurrent genital herpes simplex infection.

OBJECTIVE: To compare the efficacy and safety of oral acyclovir (400 mg twice daily) with oral isoprinosine (500 mg twice daily) in the suppression of recurrent genital herpes. DESIGN: Double-blind, double-dummy, randomised, controlled, parallel group trial. SETTING: 13 centres in UK, Belgium and Germany. SUBJECTS: 127 immunocompetent patients with frequently recurring genital herpes. MAIN OUTCOME MEASURES: Proportions of patients reporting recurrences, recurrence frequency, and mean duration of lesions during breakthrough recurrences in each treatment group during a 6 month treatment period; time to first recurrence during treatment and follow-up after treatment cessation. RESULTS: During treatment, acyclovir recipients showed significant differences (p < 0.05) when compared with isoprinosine recipients in terms of a lower proportion reporting recurrences (31% vs 96%), a reduced mean number of reported recurrences per patient (0.6 vs 3.6), a shorter mean duration of breakthrough lesions (6.4 days vs 8.2 days), and a longer mean time (standard error) to first recurrence (143.7 (9.1) days vs 40.5 (5.4) days. The mean time to first recurrence after treatment cessation did not differ between the two groups. As compared with placebo recipients, isoprinosine treated patients had an increased recurrence frequency (3.6 vs 2.5) during treatment, and a shorter time to first recurrence after treatment cessation. All treatments were well tolerated without serious adverse events or toxicity. CONCLUSIONS: Acyclovir is very effective in suppressing recurrent genital herpes and is clearly superior to isoprinosine which is not clinically useful in the dosage studied.

Evaluation of P53 protein overexpression, Ki67 proliferative activity and mitotic index as markers of tumour recurrence in superficial transitional cell carcinoma of the bladder.

OBJECTIVES: To confirm the interrelationship between p53, ki67, mitotic index with others known prognostic factors such us stage, grade, multifocality, tumour size, history of recurrence in transitional cell carcinoma (TCC) of the bladder and to determine the prognostic impact of p53, Ki67 and mitotic index in predicting recurrence in superficial bladder cancer. METHODS: Two hundred and fourteen patients with apparently superficial TCC of the bladder underwent TURBT and the 192 histologically Ta-T1 were divided into 104 primary lesions (group 1, mean follow-up 26 months) and 88 recurrent tumours (group 2, mean follow-up 28 months). Data concerning focality, tumour size, number of recurrences and recurrence-free survival were considered in each patients. All samples were immunohistochemically stained with p53 and Ki67 monoclonal antibodies. Mitotic index (MI) was calculated on haematoxylin and eosin stained sections. RESULTS: Recurrence-free survival was significantly lower in superficial recurrent tumours (group 2) compared with primary tumours (group 1). P53 staining was correlated with grade and stage for both 5 and 20% positivity thresholds. Ki67 and MI were significantly different over strata defined by stage, grade and focality in both patients groups but only Ki67 showed a correlation with p53 status. Recurrence-free survival could not be predicted either by p53 status or MI. A 20% cut-off level of Ki67 staining resulted a good predictor of recurrence in group 1 Ta-T1/G1-G2 tumours (p = 0.03). Only Ki67 and multifocality were found to be independent prognostic factors of recurrence in multivariate analysis. Stratifying Ta-T1/G1-G2 patients according to these variables, Ki67 provided a useful tool to predict early recurrence in monofocal lesions from both groups. CONCLUSIONS: P53 and MI despite a fairly good correlation with traditional prognostic factors in bladder TCC seem to play no role in the prediction of tumoural recurrence. A Ki67 index over 20% predicts those single well-differentiated (Ta-T1/G1-G2) tumours which are likely to recur within one year of treatment.

Long-term risk of first recurrent stroke in the Perth Community Stroke Study.

BACKGROUND AND PURPOSE: Few community-based studies have examined the long-term risk of recurrent stroke after an acute first-ever stroke. This study aimed to determine the absolute and relative risks of a first recurrent stroke over the first 5 years after a first-ever stroke and the predictors of such recurrence in a population-based series of people with first-ever stroke in Perth, Western Australia. METHODS: Between February 1989 and August 1990, all people with a suspected acute stroke or transient ischemic attack of the brain who were resident in a geographically defined region of Perth, Western Australia, with a population of 138 708 people, were registered prospectively and assessed according to standardized diagnostic criteria. Patients were followed up prospectively at 4 months, 12 months, and 5 years after the index event. RESULTS: Three hundred seventy patients with a first-ever stroke were registered, of whom 351 survived >2 days. Data were available for 98% of the cohort at 5 years, by which time 199 patients (58%) had died and 52 (15%) had experienced a recurrent stroke, 12 (23%) of which were fatal within 28 days. The 5-year cumulative risk of first recurrent stroke was 22.5% (95% confidence limits [CL], 16.8%, 28.1%). The risk of recurrent stroke was greatest in the first 6 months after stroke, at 8.8% (95% CL, 5.4%, 12.1%). After adjustment for age and sex, the prognostic factors for recurrent stroke were advanced, but not extreme, age (75 to 84 years) (hazard ratio [HR], 2.6; 95% CL, 1.1, 6.2), hemorrhagic index stroke (HR, 2.1; 95% CL, 0.98, 4.4), and diabetes mellitus (HR, 2.1; 95% CL, 0.95, 4.4). CONCLUSIONS: Approximately 1 in 6 survivors (15%) of a first-ever stroke experience a recurrent stroke over the next 5 years, of which 25% are fatal within 28 days. The pathological subtype of the recurrent stroke is the same as that of the index stroke in 88% of cases. The predictors of first recurrent stroke in this study were advanced age, hemorrhagic index stroke, and diabetes mellitus, but numbers of recurrent events were modest. Because the risk of recurrent stroke is highest (8.8%) in the first 6 months after stroke, strategies for secondary prevention should be initiated as soon as possible after the index event.

Risk factors for postsurgical trichiasis recurrence in a trachoma-endemic area.

PURPOSE: The World Health Organization recommends trichiasis surgery to prevent blindness caused by trachoma; however, recurrence is common. Risk factors for recurrence have not been widely studied, particularly in trachoma hyperendemic areas. METHODS: Three hundred ninety-four persons with trichiasis in Tanzania were examined. Participants had undergone surgery >18 months before the study. Trichiasis recurrence and active trachoma at study visit were assessed. Ocular swabs were collected and tested for Chlamydia trachomatis. Household members were examined for active trachoma. RESULTS: Of the surgical eyes, 28% had recurrence; 40% of patients had recurrence in one or both eyes. Rates did not vary by time since surgery. Eye-level recurrence rates varied significantly across districts, ranging from 16% to 38%. Current chlamydial infection among surgical cases was low (6%) and was not associated with recurrence. Recurrence was associated with tarsal conjunctival inflammation (OR: 2.4; 95% confidence interval [CI]: 1.6-3.8) and residence in the Kongwa district (OR: 2.3; 95% CI: 1.2-4.6). CONCLUSIONS: Recurrence after trichiasis surgery is high, suggesting that vigilant follow-up in surgical cases is needed to reduce blindness. Recurrence is associated with evidence of inflammation in the tarsal conjunctiva, although it is not clear whether the inflammation contributes to recurrence, or is a result of the recurrence. Longitudinal studies of trichiasis patients after surgery are needed.

Annual hazard rates of recurrence for breast cancer after primary therapy.

PURPOSE: To determine if the long-term increase of recurrence for breast cancer is stable or slowly decreasing, or if it ever reaches zero; and to determine the effect of prognostic factors on the hazard of recurrence. METHODS: All patients entered onto the seven completed and unblinded Eastern Cooperative Oncology Group (ECOG) coordinated studies of postoperative adjuvant therapy for breast cancer were analyzed in terms of annual hazard of recurrence of breast cancer. RESULTS: For the entire group, the peak hazard of recurrence occurred in the interval of 1 to 2 years. The hazard decreased consistently in the interval of 2 to 5 years. Beyond 5 years, the hazard of recurrence decreased very, very slowly through year 12. The average hazard of recurrence between years 5 and 12 for the entire population was 4.3% per year. The pattern of a peak hazard of recurrence during the first 5 years with a slowly decreasing hazard of recurrence beyond 5 years was also observed to varying degrees in most subsets. Higher risk subsets such as patients with more than three nodes positive had a higher hazard of recurrence at all time intervals, while lower risk subsets such as patients with negative nodes had a lower hazard of recurrence in all time periods. CONCLUSION: Patients 5 years postsurgery for breast cancer appear to have a very slowly decreasing hazard of recurrence. The mean hazard of recurrence between years 5 to 12 postsurgery is 4.3% per year. This group of patients may be well suited for trials evaluating cytostatic drugs or differentiating agents.

Skin recurrences after breast-conserving therapy for early-stage breast cancer.

PURPOSE: To assess the frequency and prognosis of skin recurrences after breast-conserving therapy (BCT) compared with other breast recurrences. MATERIALS AND METHODS: From 1968 to 1986, 1,624 patients with unilateral stage I or II breast cancer treated with BCT at the Joint Center for Radiation Therapy (Boston, MA) underwent gross tumor excision and received a dose of > or = 60 Gy to the tumor bed. Skin recurrences (SR) were defined as breast recurrences without associated parenchymal disease. An invasive breast recurrence with any parenchymal disease noted clinically or radiographically was scored as an other breast recurrence (OBR). Median follow-up for survivors was 137 months. RESULTS: SR represented 8% (18 of 229) of all breast recurrences and occurred in 1.1% of all patients. The outcome after local recurrence was different for patients with SR and invasive OBR. Patients with SR more frequently had uncontrolled local failure (50%; 9 of 18) than did patients with OBR (14%; 26 of 188) (P = .0007). Forty-four percent (8 of 18) of patients with SR had distant metastasis simultaneously or within 2 months of the recurrence compared with 5% (9 of 188) of invasive OBR patients (P < .0001). For patients without distant metastasis at the time of recurrence, the 5-year actuarial rate of development of distant metastasis was 60% for SR patients compared with 39% for invasive OBR patients (P = .07), and the corresponding 5-year actuarial survival rates beyond the time of local failure were 51% and 79%, respectively (P = .06). CONCLUSION: In contrast to other types of invasive breast recurrence after breast-conserving therapy, skin recurrences are rare and are associated with a significantly higher rate of distant metastasis and uncontrolled local disease as well as a lower rate of survival.

Predictors of recurrent stroke in African Americans.

BACKGROUND: Stroke incidence and mortality are disproportionately higher among African Americans than among whites. OBJECTIVE: To describe the recurrent stroke characteristics and determine the predictability of known vascular risk factors for stroke recurrence in African Americans. METHODS: The authors followed 1,809 African Americans in the African-American Antiplatelet Stroke Prevention Study with recent noncardioembolic ischemic stroke for recurrent stroke, recurrent stroke subtype, and disability. RESULTS: Of the subjects, 10.6% experienced a recurrent stroke during follow-up. The mean interval between eligibility and recurrent stroke was 325 days (median 287 days, SD = 224 days). Stroke recurrence resulted in an average 1.5-point increase in the National Institute of Health Stroke Scale (p < 0.001) and a 3.5-point decrease in modified Barthel Index (p < 0.001). Of previously nondisabled subjects, 48% became disabled or died after stroke recurrence (p < 0.0001). Longitudinal analysis resulted in a hazard for recurrent stroke for each 10-mm Hg increase in systolic blood pressure of 1.103 (95% CI: 1.031 to 1.179, p = 0.004), pulse pressure 1.123 (95% CI: 1.041 to 1.213, p = 0.003), and mean arterial pressure 1.123 (95% CI: 1.001 to 1.260, p = 0.048). Multivariate analysis revealed increases in the recurrent stroke hazard for increases in baseline Glasgow Outcome Score (1.449, 95% CI: 1.071 to 1.961, p = 0.016) and increases in longitudinal pulse pressure (1.009, 95% CI: 1.001 to 1.017, p = 0.029). CONCLUSION: Recurrent stroke leads to disability and disability predicts recurrent stroke. Hypertension is the most predictive modifiable stroke risk factor.

Time frame and predictors of recovery from disability following recurrent ischemic stroke.

OBJECTIVE: To assess the rate, degree, and predictors of recovery from a disabled to nondisabled state in patients disabled after recurrent ischemic stroke. METHODS: Patients with ischemic stroke enrolled in the Management of Atherothrombosis with Clopidogrel in High Risk Patients (MATCH) Study underwent prospective assessment of their modified Rankin score (mRS) at 1, 3, 6, 12, and 18 months after enrollment and after recurrent stroke. Patients disabled (defined as mRS > or = 3) after recurrence were analyzed for recovery (defined as mRS < 3) during the 18 months, and predictors of recovery were sought using a Cox proportional-hazard multiple regression analysis. RESULTS: Three hundred forty-five (54%) of 637 patients were disabled after recurrent ischemic stroke; 115 (33%) patients had been disabled and 230 (66%) nondisabled before stroke recurrence. At recurrence, the degree of disability was moderate (mRS 3) in 135 (39%) patients, severe (mRS 4) in 139 (40%), and very severe (mRS 5) in 71 (21%). After 12 months' median follow-up, 117 (34%, 95% CI: 29 to 39%) had recovered: 68 (50%, 42 to 59%) of 135 moderately disabled, 45 (32%, 25 to 41%) of 139 severely disabled, and 4 (6%, 2 to 14%) of 71 very severely disabled; 70 (20.3%) patients died. From recurrence, median time to recovery was 6 months (mRS 3) and 18 months (mRS 4); 94% with very severe disability had not recovered at 18 months. Independent predictors of recovery were moderate disability at recurrence (mRS 3) compared with severe (mRS 4: hazard ratio [HR] 1.5; 95% CI 1.04 to 2.3) or very severe disability (mRS 5: HR 7.6; 2.7 to 20) and a nondisabled vs disabled state before recurrence (HR 4.0; 2.3 to 6.8). CONCLUSIONS: The rate of recovery from recurrent ischemic stroke was greatest in the first 6 months; one-third of patients recovered within 12 months. The significant predictors of recovery were a nondisabled state before recurrence and increasing severity of the recurrent stroke.

Effects of l-thyroxine administration, TSH-receptor antibodies and smoking on the risk of recurrence in Graves' hyperthyroidism treated with antithyroid drugs: a double-blind prospective randomized study.

OBJECTIVE: In Graves' hyperthyroidism treated with antithyroid drugs (ATD), the overall relapse rate reaches 30-50% following ATD discontinuation. Conflicting results have previously been reported with regard to the usefulness of combining ATD with thyroxine (l-T4), and thereafter maintaining l-T4 treatment after ATD withdrawal. Also, clinicians are in search of useful parameters to predict the risk of a recurrence of hyperthyroidism after ATD treatment. DESIGN: Eighty-two consecutive patients (70 women and 12 men; mean age 36 years) with a first episode of Graves' hyperthyroidism were investigated prospectively; they were treated with ATD for a total of 15 months, combined with l-T4 (for at least 12 months) after they had reached euthyroidism, with the aim of maintaining serum TSH below 2.5 mU/l during the combined therapy. Following ATD discontinuation, the patients were randomly assigned (double-blind placebo-controlled trial) to taking 100 microg/day l-T4 (vs placebo) for an additional year. METHODS: The following determinations were carried out at initial diagnosis: serum total T4 and tri-iodothyronine (T3), free T4 and T3, TSH, TSH-receptor antibodies (TSHR-Ab), thyroid scintigraphy and echography. During ATD treatment, serum free T4 and T3 and TSH concentrations were recorded after 1 (optional), 2, 4, 6, 9, 12 and 15 months, and echography at the end of ATD treatment. During the randomized trial, serum free T4 and T3 and TSH concentrations were checked every 3 months (or until a recurrence). TSHR-Ab titers were measured at initial diagnosis, after 6 months with ATD, and at the end of ATD treatment. RESULTS: l-T4 administration, both during and after ATD treatment, did not improve the final outcome and recurrence rates were similar in placebo and l-T4-treated patients (30%). Two parameters were identified that might be useful to help predict recurrence risks after ATD: (i) positive TSHR-Ab (at the end of ATD treatment) was significantly associated with a greatly increased recurrence risk; and (ii) despite the relatively small number of patients who were smokers, regular cigarette smoking was shown, for the first time, to be significantly associated with an increased recurrence risk. Also, the deleterious effect of smoking was shown to manifest its impact independently of TSHR-Ab titers at the end of ATD treatment. Thus, compared with the overall 30% recurrence risk, non-smoking patients with a negative TSHR-Ab (at the end of ATD) had a lower (18%) recurrence risk; smoking patients with negative TSHR-Ab (at the end of ATD) had a 57% recurrence risk; non-smoking patients with positive TSHR-Ab (at the end of ATD) had a high (86%) recurrence risk; the recurrence risk was 100% in those few patients who both smoked and maintained a positive TSHR-Ab at the end of ATD treatment. CONCLUSIONS: The present study confirmed that l-T4 administration during and after ATD withdrawal did not improve remission rate. Two factors, namely positive TSHR-Ab at the end of ATD treatment and regular smoking habits may represent clinically useful (albeit not absolute) predictors of the risk of recurrence in patients with Graves' hyperthyroidism treated with ATD. However, due to the relatively small number of smoking patients in the present cohort, this conclusion needs to be confirmed by a larger study.

Recurrence of focal segmental glomerulosclerosis posttransplantation: a special report of the North American Pediatric Renal Transplant Cooperative Study.

Among various forms of glomerulonephritis, focal segmental glomerulosclerosis (FSGS) is the most common cause of end-stage renal disease leading to transplantation in children. Previous reports of the recurrence of FSGS vary widely. The North American Pediatric Renal Transplant Cooperative Study carried out a special study to determine the rate of recurrence and risk factors leading to recurrence in 132 transplants. Fifty-five percent of the patients were white children, and the remaining were black and Hispanic children. Fifty percent of the patients were under 5 yr of age at the time of the diagnosis of FSGS. Twenty-seven (20.5%) of 132 patients (95% confidence interval, 14 to 27) had a biopsy-proven recurrence of FSGS. The median time to recurrence was 14 days. The recurrence rate was similar in white children (23%) when compared with that in Hispanic children (20%) but was lower than that in black children (9%) (3 of 32 children).2+ (20%). The mean serum albumin level of patients with recurrence was 1.7 versus 2.0 g/dL for those without recurrence. The mean serum cholesterol level of patients with recurrence was 525 versus 476 mg/dL for those without recurrence. The duration of dialysis was similar in the two groups. The mean time from diagnosis to end-stage renal disease status was 33 months for patients with recurrence and 52 months for those without recurrence (P less than 0.05).(ABSTRACT TRUNCATED AT 250 WORDS)

Risk factors for recurrence of shoulder instability after arthroscopic Bankart repair.

BACKGROUND: The higher failure rates reported with arthroscopic stabilization of traumatic, recurrent anterior shoulder instability compared with open stabilization remain a concern. The purpose of this study was to evaluate the outcomes of arthroscopic Bankart repairs with the use of suture anchors and to identify risk factors related to postoperative recurrence of shoulder instability. METHODS: Ninety-one consecutive patients underwent arthroscopic stabilization for recurrent anterior traumatic shoulder instability. The mean age (and standard deviation) at the time of surgery was 26.4 +/- 5.4 years. Seventy-one patients were male. Seventy-nine patients were involved in sports (forty, in high-risk sports). Capsulolabral reattachment and capsule retensioning was performed with use of absorbable suture anchors (mean, 4.3 anchors; range, two to seven anchors). All patients were prospectively followed, and, at the time of the last review, the patients were examined and assessed functionally by independent observers. RESULTS: At a mean follow-up of thirty-six months, fourteen patients (15.3%) experienced recurrent instability: six sustained a frank dislocation and eight reported a subluxation. The mean delay to recurrence was 17.6 months. The risk of postoperative recurrence was significantly related to the presence of a bone defect, either on the glenoid side (a glenoid compression-fracture; p = 0.01) or on the humeral side (a large Hill-Sachs lesion; p = 0.05). By contrast, a glenoid separation-fracture was not associated with postoperative recurrent dislocation or subluxation. Recurrence of instability was significantly higher in patients with inferior shoulder hyperlaxity (p = 0.03) and/or anterior shoulder hyperlaxity (p = 0.01). On multivariate analysis, the presence of glenoid bone loss and inferior hyperlaxity led to a 75% recurrence rate (p < 0.001). Lastly, the number of suture-anchors was critical: patients who had three anchors or fewer were at higher risk for recurrent instability (p = 0.03). CONCLUSIONS: In the treatment of traumatic recurrent anterior shoulder instability, patients with bone loss or with shoulder hyperlaxity are at risk for recurrent instability after arthroscopic Bankart repair. At least four anchor points should be used to obtain secure shoulder stabilization.

Transitional cell carcinoma of the bladder: patterns of recurrence after cystectomy as determined by CT.

CT scans have been recommended for examination of patients at risk for recurrent transitional cell carcinoma after cystectomy. For CT to be useful in this regard, the location and type of recurrences must be known, so that appropriate scans can be made. Therefore, we retrospectively studied CT scans in 27 postcystectomy patients with recurrent transitional cell carcinoma of the bladder to identify the type and location of the recurrent disease. Recurrence was documented by biopsy in 18 patients and by progression of disease shown on serial CT scans in nine patients. All 27 patients had pelvic CT, and 23 had concomitant abdominal CT. Tumor recurred at the cystectomy site in 10 (37%) of 27 patients, pelvic adenopathy was present in 18 (67%) of 27 patients, and retroperitoneal adenopathy was present in 13 (57%) of 23 patients. Tumor recurrence at the cystectomy site was associated with pelvic adenopathy in seven of 10 patients, and the cystectomy site was the solitary site of disease in the remaining three patients. Conversely, in 11 of 18 patients with pelvic adenopathy no recurrence was seen at the cystectomy site. Combined retroperitoneal and pelvic adenopathy was identified in 11 of 23 patients, but two patients had retroperitoneal lymphadenopathy as their only site of recurrence. Hepatic metastases were seen in seven (30%) of 23 patients; six of these seven patients had metastases elsewhere. In four of five patients in whom underestimation of recurrent disease occurred, the deep pelvis and/or deep perineal space were involved. Our results show that the pelvis is the most common site for recurrence. Cystectomy site or retroperitoneal nodal recurrences are usually accompanied by pelvic adenopathy, but the converse is not as common. Our findings of deep perineal and isolated abdominal recurrences indicate that proper protocol for CT follow-up of the postcystectomy patient should include abdominal scans and scans through the perineum.

Prediction of recurrence and prognosis in patients with hepatocellular carcinoma after resection by use of CLIP score.

AIM: The survival time of patients with hepatocellular carcinoma (HCC) after resection is hard to predict. Both residual liver function and tumor extension factors should be considered. A new scoring system has recently been proposed by the Cancer of the Liver Italian Program (CLIP). CLIP score was confirmed to be one of the best ways to stage patients with HCC. To our knowledge, however, the literature concerning the correlation between CLIP score and prognosis for patients with HCC after resection was not published. The aim of this study is to evaluate the recurrence and prognostic value of CLIP score for the patients with HCC after resection. METHODS: A retrospective survey was carried out in 174 patients undergoing resection of HCC from January 1986 to June 1998. Six patients who died in the hospital after operation and 11 patients with the recurrence of the disease were excluded at 1 month after hepatectomy. By the end of June 2001, 4 patients were lost and 153 patients with curative resection have been followed up for at least three years. Among 153 patients, 115 developed intrahepatic recurrence and 10 developed extrahepatic recurrence, whereas the other 28 remained free of recurrence. Recurrences were classified into early (< or =3 year) and late (>3 year) recurrence. The CLIP score included the parameters involved in the Child-Pugh stage (0-2), plus macroscopic tumor morphology (0-2), AFP levels (0-1), and the presence or absence of portal thrombosis (0-1). By contrast, portal vein thrombosis was defined as the presence of tumor emboli within vascular channel analyzed by microscopic examination in this study. Risk factors for recurrence and prognostic factors for survival in each group were analyzed by the chi-square test, the Kaplan-Meier estimation and the COX proportional hazards model respectively. RESULTS: The 1-, 3-, 5-, 7-,and 10-year disease-free survival rates after curative resection of HCC were 57.2%, 28.3%, 23.5%, 18.8%, and 17.8%, respectively. Median survival time was 28, 10, 4, and 5 mo for CLIP score 0, 1, 2, 3, and 4 to 5, respectively. Early and late recurrence developed in 109 patients and 16 patients respectively. By the chi-square test, tumor size, microsatellite, venous invasion, tumor type (uninodular, multinodular, massive), tumor extension (< or = or >50% of liver parenchyma replaced by tumor), TNM stage, CLIP score, and resection margin were the risk factors for early recurrence, whereas CLIP score and Child-Pugh stage were significant risk factors for late recurrence. In univariate survival analysis, Child-Pugh stages, resection margin, tumor size, microsatellite, venous invasion, tumor type, tumor extension, TNM stages, and CLIP score were associated with prognosis. The multivariate analysis by COX proportional hazards model showed that the independent predictive factors of survival were resection margins and TNM stages. CONCLUSION: CLIP score has displayed a unique superiority in predicting the tumor early and late recurrence and prognosis in the patients with HCC after resection.

Detection and prognosis of recurrent gastric cancer--is routine follow-up after gastrectomy worthwhile?

BACKGROUND/AIMS: Although routine follow-up after surgery for gastric cancer is recommended its value after gastrectomy has not been evaluated. METHODOLOGY: All patients who underwent gastrectomy for gastric cancer entering the routine follow-up program between January 1987 and August 1996 were identified. The patients studied were those with either histologically proven recurrence or those in whom recurrence was highly probable from clinical course. Two groups were compared. The first group comprised the patients whose recurrence was detected by routine follow-up prior to the development of clinical signs (asymptomatic group). The second group consisted of the patients who developed clinical symptoms due to a recurrence that was detected subsequently (symptomatic group). The main parameters were the time until recurrence occurred, the pattern of recurrence, treatment and survival. RESULTS: Out of 184 patients entering the routine follow-up 135 patients had undergone potentially curative gastrectomy. Sixty-seven patients (49.6%) had recurrences. Only 15 (22.3%) belonged to the asymptomatic group and 52 (77.7%) to the symptomatic one. The time until recurrence occurred was not different between the 2 groups (17.1 vs. 18.0 months). Chemotherapy was performed more frequently in the asymptomatic group and survival was longer (8.4 vs. 5.9 months). This difference was due to the time the patients remained asymptomatic (average 43 months). No effect of either early detection or chemotherapy was seen. In the asymptomatic group distant recurrence was common while recurrence in the symptomatic group was more often local but this difference did not reach statistic significance. CONCLUSIONS: Routine follow-up after gastrectomy for gastric cancer does not contribute to early detection of gastric cancer recurrence. It has no benefit with respect to treatment and survival of patients with recurrent disease and should therefore be reduced to symptomatic and psychological aftercare.

Clinicopathological characteristics of patients with extrahepatic recurrence following a hepatectomy for hepatocellular carcinoma.

BACKGROUND/AIMS: None of the previous studies have compared the prognosis or clinicopathological factors between the patients with extrahepatic recurrence and those with intrahepatic recurrence of hepatocellular carcinoma after a hepatic resection. METHODOLOGY: The clinicopathological features and prognoses of patients with extrahepatic recurrence after a curative hepatectomy for hepatocellular carcinoma were investigated. RESULTS: Twenty-three patients with extrahepatic recurrence had more advanced-stage hepatocellular carcinoma at the primary operation compared to 186 patients with intrahepatic recurrence. After adjusting for tumor size, the prognosis of the 2 groups were comparable. However, among the patients with hepatocellular carcinoma exceeding 5 cm in diameter, the number of patients whose plasma levels of des-gamma-carboxy prothrombin was higher than 2.0 AU/mL in the patients with extrahepatic recurrence (62.5%) was significantly more (P < 0.05) than that in the patients with intrahepatic recurrence (20.0%). On the other hand, the prognosis of the 13 patients with extrahepatic recurrence alone was significantly better than in the 10 patients with both intrahepatic and extrahepatic recurrences. The prognoses of the 3 patients who underwent a surgical resection for isolated extrahepatic recurrence were markedly better than that of the remaining 10 patients only treated palliatively. CONCLUSIONS: If patients have tumors exceeding 5 cm in diameter and their plasma levels of des-gamma-carboxy prothrombin are higher than 2.0 AU/mL, more careful follow-up examinations than usual may thus be necessary in order to detect extrahepatic recurrence as early as possible. Furthermore, a surgical resection for the isolated extrahepatic recurrence of hepatocellular carcinoma is also recommended to produce long-term survivors.

[Consideration of surgical treatment for recurrence after the resection of hepatic metastases from colorectal cancer].

We considered treatment for recurrence following the resection of hepatic metastases from colorectal cancer. The subjects of this study were 15 of 29 patients who had undergone WHF arterial infusion following resection of hepatic metastases from colorectal cancer, in whom there was a recurrence. Of these 15 cases, 6 involved recurrence in a single organ (residual liver, 4; lung, 1; local area, 1), 7 involved two organs (residual liver and lung, 2; residual liver and local area, 2; residual liver and bone, 1; spleen and intra-abdominal lymph node, 1; intra-abdominal lymph node and peritoneum, 1) and 2 involved three organs (lung, bone and abdominal wall, 1; lung, peritoneum and distal lymph node, 1). Reresection was performed in all cases in which recurrence occurred in a single organ. For those cases in which recurrence occurred in two or more organs, reresection and infusion were performed in the 4 cases of recurrence in the residual liver and reresection was performed in the case of recurrence in the spleen and intra-abdominal lymph node (No. 16), the case of local recurrence and the case involving the abdominal wall. The 5-year survival rate of the 29 cases who underwent initial hepatic resection was 61.9%. Five years following resection, the recurrence rate in the residual liver was 38.3%. The survival rates following treatment for recurrence were 76.9, 51.3 and 25.6% for 1, 3 and 5 years, respectively. Of the 8 deaths which have occurred to date, only one was directly related to an increase in hepatic metastases. Following resection of hepatic metastases from colorectal cancer, WHF provides a high rate of prevention as well as a high survival rate. Furthermore, with regard to recurrence following WHF treatment, if the recurrence is in only one organ, there is the possibility of achieving effective treatment by reresection (WHF = 5-FU 1,000 mg/m2 5 hrs qw).
