Prognosis versus actual outcome. II. The effectiveness of clinical parameters in developing an accurate prognosis.

The assignment of prognosis is one of the most important functions undertaken in clinical practice, yet there is little evidence to support the current decision-making process which is based on an outdated model of disease etiology and progression. This study evaluated 100 treated periodontal patients (2,484 teeth) under maintenance care for 5 years, with 38 of these patients followed for 8 years, to determine the relationship of assigned prognoses to the clinical criteria commonly used in the development of prognosis. The method of generalized estimating equations (GEE) for correlated data was utilized to determine the relationship of each clinical factor to the assignment of initial prognosis, improvement in prognosis at 5 years, and worsening in prognosis at 5 years. A multiple linear regression model was constructed for predicting initial prognosis based on initial clinical data. Increased probing depth, more severe furcation involvement, greater mobility, unsatisfactory crown-to-root ratio, malpositioned teeth, and teeth used as fixed abutments resulted in worse initial prognoses. The coefficients from this model were able to predict accurately the 5-year and 8-year prognoses 81% of the time. When teeth with "good" prognoses were excluded, the predictive accuracy dropped approximately 50%. Multiple logistic regression models indicated that improvement in prognoses and worsening in prognoses were both strongly associated with initial probing depth, initial furcation involvement, initial tooth malposition, and smoking when adjusted for initial prognosis. In addition, good hygiene was found to increase the probability of improvement in prognosis while initial mobility was found to decrease the likelihood of improvement in prognosis. Neither of these factors was found to be significant in worsening of prognosis. Smoking decreased the likelihood of improvement by 60% and doubled the likelihood of worsening in prognosis at 5 years. The results of this study indicate that some clinical factors used in the assignment of prognoses are clearly associated with changes in clinical condition over time. The data also demonstrated that the traditional approach for assigning prognoses is ineffective for teeth with an initial prognosis of less than good. Since most periodontally involved teeth are compromised, further work should include the development of a more effective method for assigning prognoses that is based on clear, objective clinical criteria.

Effects of gender and race on prognosis after myocardial infarction: adverse prognosis for women, particularly black women.

Controversy has arisen concerning whether gender influences the prognosis after myocardial infarction. Although some studies have shown there to be no difference between the sexes, most have indicated a worse prognosis for women, attributing this to differences in baseline characteristics. It has been further suggested that black women have a particularly poor prognosis after infarction. To determine the contribution of gender and race to the course of infarction, 816 patients with confirmed myocardial infarction who were enrolled in the Multicenter Investigation of the Limitation of Infarct Size (MILIS) were analyzed. Of those patients, 226 were women and 590 were men, 142 were black and 674 were white. The cumulative mortality rate at 48 months was 36% for women versus 21% for men (p less than 0.001, mean follow-up 32 months). The cumulative mortality rate by race was 34% for blacks versus 24% for whites (p less than 0.005). Both women and blacks exhibited more baseline characteristics predictive of mortality than did their male or white counterparts. It was possible to account for the greater mortality rate of blacks by identifiable baseline variables; however, even after adjustment, the mortality rate for women remained significantly higher (p less than 0.002). The poorer prognosis for women was influenced by a particularly high mortality rate among black women (48%); the mortality rate for white women was 32%, for black men 23% and for white men 21%. The mortality for black women was significantly greater than that of the other subgroups. Thus, findings in the MILIS population indicate that the prognosis after myocardial infarction is worse for women, particularly black women.

Perceptions of prognosis, treatment, and treatment impact on prognosis in non-small cell lung cancer.

STUDY OBJECTIVES: We designed and performed a survey to assess the roles and knowledge level of physicians, by specialty, in the management of non-small cell lung cancer (NSCLC). The primary objective was to evaluate the potential variability of physician perceptions of prognosis, recommended treatments, and the impact of treatment on prognosis for each stage of NSCLC. DESIGN: A random national sample of physicians from one of five specialties (primary care, pulmonary medicine, medical oncology, radiation oncology, or thoracic surgery) were invited to complete a 15-min questionnaire. Five case scenarios were presented, each representing a different stage of NSCLC. Participants were asked to state the expected prognosis, recommended treatment, and expected impact of the recommended treatment on prognosis for each scenario. MEASUREMENTS AND RESULTS: Of the 442 physicians contacted, 350 completed the survey (86% response rate). In general, physicians agreed that the primary treatment of patients with stage I disease should be surgery. For all other stages of disease, however, there was a wide range of opinion regarding the treatment of choice and expected impact of treatment on prognosis. In particular, a significant proportion of physicians recommended only supportive care for patients with stage IV disease, despite demonstrated benefits of chemotherapy. CONCLUSIONS: Physicians from differing specialties have varied opinions on the management of NSCLC, particularly stages II to IV. Education regarding state-of-the-art therapy should be directed not only at traditional audiences (ie, medical oncologists) but also the major physician specialties involved in the care of NSCLC patients. Wider implementation of treatment advances in late-stage disease could significantly increase the numbers of patients living for a longer time.

CHOP-firstline treatment in NHL with unfavorable prognosis--evaluation of therapeutic response and factors influencing prognosis.

58 NHL-patients (9 large cell centrocytic, 18 centroblastic, 16 immunoblastic, 15 lymphoblastic lymphomas) were treated immediately after diagnosis with CHOP-chemotherapy regardless of the extent of disease. Because of the advanced age of the majority of patients (median age 61 years, range 22-85 years) a reduced dose in the first two cycles was administered. Statistically significant prognostic variables influencing survival were the following: histologic subtypes according to the Kiel-classification (p less than 0,05), B-symptoms (p less than 0,001), blood sedimentation rate (p less than 0,02) and LDH (p less than 0,0005). With regard to prognosis there was no difference between patients over 60 years of age and younger ones (p less than 0,4). Patients achieving complete remission survived significantly longer (p less than 0,0001). Ann Arbor stages were of limited value, since patients with CS II disease and accumulation of risk factors (B-symptoms, abdominal disease, bulky tumor masses) showed a poorer outcome than patients with CS III who did not have these risk factors. A risk factor score summarizing features influencing prognosis is described and might be a useful tool in stratifying the heterogeneous group of NHL with unfavorable prognosis.

Cardiovascular prognosis in relation to apolipoproteins and other lipid parameters in patients with stable angina pectoris treated with verapamil or metoprolol: results from the Angina Prognosis Study in Stockholm (APSIS).

Relationships between apolipoproteins and other lipid parameters and cardiovascular (CV) prognosis were evaluated in the Angina Prognosis Study In Stockholm (APSIS). Out of 809 patients with stable angina pectoris, lipid variables were obtained in 786 patients at baseline, and after one month's double-blind treatment with metoprolol or verapamil, to evaluate treatment effects on these lipid variables. During a median follow-up time of 3.3 years (2663 patient years), 37 patients suffered a CV death, 30 suffered a non-fatal myocardial infarction (MI) and 100 underwent a revascularization. Apolipoprotein (apo) A-I, high-density lipoprotein cholesterol and triglycerides were predictors of CV death or non-fatal MI in univariate analyses, but only apo A-I remained as an independent predictor in multivariate analyses. All lipid variables except low density lipoprotein cholesterol were related to the risk of revascularization in univariate analyses, but only apo A-I and apo B were independent predictors of such events. Triglycerides were weakly, but not independently, associated with prognosis. Verapamil and metoprolol had differential short-term effects on lipids, with a shift towards a more atherogenic profile in metoprolol treated patients. However, there was no significant impact of the treatment given, or of these treatment effects on the risk of CV events. Results of the present study suggest that apolipoprotein levels were better predictors of CV events than other lipid parameters in patients with stable angina pectoris.

Randomized trial of CVPP for three versus six cycles in favorable-prognosis and CVPP versus AOPE plus radiotherapy in intermediate-prognosis untreated Hodgkin's disease.

PURPOSE: To evaluate in a randomized trial the impact of three versus six cycles of cyclophosphamide, vinblastine, procarbazine, and prednisone (CVPP) chemotherapy in favorable-prognosis and CVPP versus doxorubicin, vincristine, prednisone, and etoposide (AOPE) plus involved-field radiotherapy (RT) in intermediate-prognosis previously untreated Hodgkin's disease. PATIENTS AND METHODS: Of 256 patients evaluated, 80 with a favorable prognosis according to a prognostic index designed by the Grupo Argentina de Tratamiento de Leucemia Aguda (GATLA) were randomized to three versus six cycles of CVPP without RT and 176 with intermediate risk to CVPP versus AOPE, both for six cycles with RT between the third and fourth cycles of 30 Gy to the involved areas at diagnosis. CVPP consisted of intravenous (I.V.) cyclophosphamide and vinblastine on days 1 and 8, and oral procarbazine and prednisone on days 1 to 14, every 28 days. AOPE consisted of I.V. doxorubicin and vincristine on day 1, oral prednisone on days 1 to 5, and I.V. etoposide on days 1 and 3, every 28 days. RESULTS: Complete remission was obtained in 39 of 41 (95%) patients treated with three cycles of CVPP and 36 of 39 (92%) treated with six cycles in the favorable-risk group (difference not significant [NS]). In the intermediate-risk group, 89 of 92 (97%) treated with CVPP plus RT versus 75 of 84 (89%) treated with AOPE plus RT achieved a complete remission (P = .05). At 60 months, the event-free survival (EFS) and overall survival rates in the favorable-risk group were 80% and 91% for CVPP x 3 and 84% and 97% for CVPP x 6, respectively (P = NS). In the intermediate-risk group, 60-month EFS rate for CVPP plus RT was 85%, compared with 66% for AOPE plus RT (P = .009). The overall survival rate was 95% versus 87% respectively (P = .157). CONCLUSION: Three cycles of CVPP without RT are equally effective as six cycles in the favorable-risk group. However, in the intermediate-group, CVPP plus RT is superior to AOPE plus RT, with significantly fewer events before and after induction (P = .009), without a difference in overall survival.

[Biological characteristics and prognosis of supraglottic carcinoma--a multivariate correlation analysis of prognosis].

The biological characteristics of supraglottic carcinoma was studied with special reference to the correlations of various biological factors with the prognosis of the lesion. The study included 100 cases of supraglottic carcinoma treated by total laryngectomy in the First Hospital of China Medical University in the period from 1975 to 1978, and 7 factors including histopathological findings observed in serial sections of the whole larynx, clinical findings, clinical course, etc. These factors were statistically analyzed by multiple correlation analysis using the theory of quantification I to determine the relations of these factors to the prognosis, as well as their participations in post operative course. 1. Twenty-seven cases died within 5 years after surgery, and 4 cases could not be followed up. 3 and 5-year survival rates were 79.5% and 72.2%, respectively, as calculated in accordance with the UICC General Rule. 2. Histopathologically 5-year survival rate was 10.0% in cases with poorly differentiated carcinoma, 78.0% in cases with moderately differentiated type, and 83.5% in cases with well-differentiated type. It was remarkably lower in poorly differentiated carcinoma than that in moderately or well-differentiated carcinoma. 3. In cases having dense lymphocyte infiltration associated with lymph follicles in peripheral region of tumor, 5-year survival rate was higher (90.4%) than in the other cases. 4. It was found that, as tumor size increased, 5-year survival rate decreased and the risk of lymph node involvement increased in the neck region. 5. 5-year survival rate was lower (48.5%) in cases with lesion infiltrating the surrounding tissues than in cases with other growth patterns. 6. Multiple correlation coefficient between prognosis and the 7 factors analyzed was 0.766. The important factors were the degree of differentiation (0.735), the degree of lymphocyte infiltration (0.260), the size of primary tumor (0.215), the growth pattern of tumor (0.141) and neck metastasis (0.028).

[Prognosis of epilepsy and suppression of treatment. Prognosis of epilepsy].

OBJECTIVE: On the occasion of the XXXVII Annual Meeting of the Spanish Anti-Epilepsy League we have reviewed the prognosis of epilepsy. DEVELOPMENT: The latest population studies of prognosis indicate that the long-term prognosis of epilepsy is good. Over 80% of these patients experience remission of their illness for at least three years, within nine years of diagnosis. The probability of remission is little influenced by the aetiology of the epilepsy. The mortality of epileptic patients is 2.5-3 times greater than that of the general population, adjusted for age, is markedly influenced by the aetiology and generally occurs within the first few years after diagnosis.

[The long-term prognosis of coronary artery bypass surgery--the influence of preoperative left ventricular volume on the prognosis of cardiac death].

We have assessed the long-term prognosis about cardiac death of isolated coronary artery bypass surgery from 1972 to 1988 in 361 consecutive patients. The duration of follow-up were from 0.4 years to 14.6 (mean 5.7) years. Of the 361 study patients, the operative morality was 4.7% (17 patients) and 29 patients (8.0%) died during follow-up, 11 (3.0%) of which were from cardiac causes. Actuarial survival rate was 85.2% at 10 years after surgery. The 10 year-survival rate was similar for patients with single, double, triple vessel disease, and left main trunk disease (94.5%, 83.7%, 75.1% and 89.1%, respectively). For patients with and without old myocardial infarction, the 10 year-survival rate was significantly different (75.4% and 93.3%, respectively) (p less than 0.005). In order to detect which factors of preoperative cardiac function among cardiac index, LV end-diastolic pressure, LV end-diastolic volume index, LV end-systolic volume index, and LV ejection fraction influenced the long-term prognosis, multivariant regression analysis was performed. Only LV end-systolic volume index was a significant factor, and the discriminative point was 50 ml/m2. For patients with LV end-systolic volume index less than 50 ml/m2 and greater than or equal to 50 ml/m2, the 10 year-survival rate was significantly different (88.3% and 32.9%, respectively) (p less than 0.005). In conclusion, the most significant factor influencing longterm prognosis after coronary artery bypass surgery was left ventricular end-systolic volume, indicating the importance of preventing preoperative dilatation of left ventricle.

Long-term prognosis of major depression in old age: a comparison with prognosis of dysthymic disorder.

The 5-year prognosis of 42 elderly patients with major depression (mean age 73.2 +/- 6.3 years for men and 73.0 +/- 7.3 years for women) is described. Furthermore, the clinical outcome of elderly patients with major depression is compared to that of 199 elderly patients with dysthymic disorder (mean age 69.9 +/- 7.2 years for men and 71.3 +/- 7.7 years for women) described in a previous article. Twelve percent of patients with major depression recovered, 26% still had depression after 5 years, 12% had possible dementia, 45% had died, and 5% could not be contacted. The outcome did not significantly differ between the sexes or the two age groups (65-74 and 75+). A poor clinical outcome of patients with major depression was related to a greater number of diagnosed diseases, strong feelings of restlessness, and higher sexual interest at the beginning of the follow-up. A poor prognosis was also found for the patients whose functional abilities and hobby activities declined during the follow-up. A poor prognosis tended to be related to absence of hypertension, frequent trembling of hands, low activity in listening to music, and high activity in watching TV at the onset, and to absence of malignant disease and occurrence of a high number of negative and positive life events during the follow-up period. Thirty-six percent of dysthymic patients recovered, 26% still had depression after 5 years, 9% had possible dementia, 25% had died and 4% could not be contacted. The outcome of dysthymic patients did not significantly differ between the sexes or the two age groups (65-74 and 75+). The clinical outcome of dysthymic patients tended to be more favorable than that of patients with major depression. The factors related to a poor outcome differed between patients with major depression and dysthymic patients.

The paradoxical association of regression with a poor prognosis in melanoma contrasted with a good prognosis in keratoacanthoma.

Partial regression in cutaneous malignant melanoma has been reported by a number of observers, albeit not all, to be associated with a relatively poor prognosis; in contrast, a keratoacanthoma, which eventually regresses, does not metastasize. The Hammond effect could explain the possibly poor prognosis of the thin regressing melanoma. Hammond(W.G. Hammond et al., Cancer J., 8: 130-138, 1995) showed that the speed of biological progression to less differentiated phenotypes is directly related to the immunocompetences of the tumor hosts. If partial regression is a sign of an unusually strong immune reaction, then the melanoma that partially regresses might have a relatively poor prognosis because of the greater risk of biological progression among the surviving tumor clones. A Hammond effect is not associated with regression of a keratoacanthoma. I postulate that the growth of this tumor is accelerated, rather than restrained, by the immune reaction and that the ultimate regression of the tumor is the result, not of immune cytotoxicity, but of a rapid terminal differentiation (a reverse Hammond effect); alternatively, very rapid growth might lead to an exhaustion of growth potential before progression to clonal immortality could occur.

Natural history and prognosis of epilepsy: report of a multi-institutional study in Japan. The group for the study of prognosis of epilepsy in Japan.

A multi-institutional study on the prognosis of patients with epilepsy was performed in Japan from 1975 to 1977, including 20 institutions. The outcome of epileptic seizures and social adjustment 10, 5, and 3 years after the onset of the illness was studied in three different groups of epileptic patients, respectively. The number of successfully followed-up cases was 1,868 in total, follow-up rate being 42%. The data were analyzed statistically by use of analysis of variance. The rate of remission of seizures in all was 58.3% and the rate of normal social adjustment 62.6%. The remission rate showed no significant difference among the 10-, 5-, and 3-year outcome groups. The study on the outcome of seizure control indicated that the prognosis of seizure control is more favorable (a) in idiopathic than in residual or symptomatic epileptics; (b) in patients with onset before 10 years of age than in those with onset after 10 years; (c) in patients with less frequent seizures; (d) in sleep epilepsy than in waking and diffuse epilepsies; (e) in patients who started treatment within 1 year of onset of seizure; (f) in patients with single-type partial seizures than in those with partial seizures combined with tonic-clonic seizures; (g) in patients without high grade EEG background abnormality; and (h) in patients without neurological symptoms, intellectual deficits, personality disturbances, or psychotic symptoms. Factors that determine the prognosis of social adjustment were almost similar to those for remission of seizures. There was a close correlation between the outcome of seizure control and that of social adjustment. Correlation coefficient between follow-up rate and remission rate in 15 of the 20 collaborated institutions was 0.55 (p less than 0.05), showing a tendency that the remission rate becomes higher as the follow-up rate is raised.

The prognosis of resected lung carcinoma associated with atypical adenomatous hyperplasia: a comparison of the prognosis of well-differentiated adenocarcinoma associated with atypical adenomatous hyperplasia and intrapulmonary metastasis.

BACKGROUND: Radiologically undetected intrapulmonary solitary nodules are sometimes found in the resected lung. When the main tumor is a well-differentiated (w/d) adenocarcinoma, especially a bronchioloalveolar carcinoma (BAC), it can be difficult to determine morphologically whether the intrapulmonary nodules are atypical adenomatous hyperplasia (AAH) or intrapulmonary metastasis (PM). The authors evaluated the accuracy of the differential diagnosis of these two lesions from the prognostic point of view. METHODS: A retrospective study was conducted of 1360 lung carcinoma patients who had undergone surgical resection. Differential diagnosis was made between AAH and PM based on the conventional histologic specimens. Their clinicopathologic features were also studied. Survival rates were compared between these two groups. RESULTS: AAH was found in 137 patients (10%) with resected lung carcinoma. The 5-year survival rates were 72.9% in Stage I, 60.6% in Stage II, 27.1% in Stage IIIA, 0% in Stage IIIB, and 0% in Stage IV. They were not significantly different from the figures for all patients in the corresponding pathologic stages. Seventy-six cases were diagnosed as w/d adenocarcinoma associated with AAH, whereas PM was found in 46 cases of w/d adenocarcinoma. The 5-year survival rates of AAH and PM differed significantly: 64.6% and 35.5%, respectively (P 0.0004). When a comparison was made between cases of pT1-2, N0 w/d adenocarcinoma, most of which were BAC, with PM (n = 22) and those with AAH (n = 52), the latter had significantly better survival (P = 0.0086). CONCLUSIONS: The prognosis of resected lung carcinoma was not affected by association with AAH. The significant difference in prognosis between AAH and PM in w/d adenocarcinoma, especially in BAC, indicates that their morphologic distinction was correctly made by conventional pathologic examination in most cases.

Inflammatory and hemostatic markers in relation to cardiovascular prognosis in patients with stable angina pectoris. Results from the APSIS study. The Angina Prognosis Study in Stockholm.

Increased inflammatory activity and platelet activation have been associated with an increased risk of cardiovascular (CV) events in epidemiological studies, but their prognostic importance in patients with stable angina pectoris is less well established. The Angina Prognosis Study in Stockholm (APSIS), comprised 809 patients (2766 patient years) with stable angina pectoris on double-blind treatment with verapamil or metoprolol. Plasma levels of fibrinogen and orosomucoid (an acute phase reactant), white blood cell counts (WBC), platelet counts and the urinary excretion of beta-thromboglobulin (reflecting platelet secretion), were related to the risk of CV death (n=36), non-fatal myocardial infarction (MI) (n=30) or revascularization (n=99) in a subgroup of 782 patients. Verapamil and metoprolol had only minor effects on the inflammatory variables. In multivariate Cox regression analyses (adjusted for previous MI, hypertension, diabetes mellitus and smoking), fibrinogen and WBC were independent predictors of CV death or non-fatal MI, as well as the risk of revascularization. Orosomucoid did not carry any independent information. Platelet counts and urinary beta-thromboglobulin were not significantly related to CV prognosis. The treatment given did not significantly influence the prognostic impact of either fibrinogen or WBC. Fibrinogen and WBC were independent predictors of CV death or non-fatal MI as well as disease progression leading to revascularization in patients with stable angina pectoris. As fibrinogen is also an acute-phase reactant, the present findings indicate that inflammatory activity is involved in disease progression in stable angina pectoris.

The expression of co-stimulatory molecules and their relationship to the prognosis of human acute myeloid leukaemia: poor prognosis of B7-2-positive leukaemia.

We examined the expression of co-stimulatory molecules on leukaemic cells of 52 adult patients with acute myeloid leukaemia (AML) (34 men and 18 women) and analysed the relationship between these expressions and the patient's prognosis. B7-1 was not expressed in any of the 23 patients investigated, whereas B7-2 was expressed in 26/52 patients (50.0%). B7-2 was expressed in all AML patients with monocytic morphology (M4 or M5) and in 16/42 cases without monocytic morphology. CD54 was expressed in 28/ 37 patients examined (75.7%), and CD58 was expressed in all of the AML patients except one (M 7). The overall survival of the 26 B7-2-positive leukaemia patients (1-24 months, median survival 11.5 months) was significantly shorter than that of the 26 B7-2-negative leukaemia patients (1-71+ months, median 35.1 months) (P=0.0080). In addition, the B7-2-positive patients exhibited significantly shorter disease-free survival periods compared to the B7-2-negative patients (P=0.021). There was no significant difference in age, sex, haematological data and complete remission rate between the B7-2-positive and B7-2-negative patients. Our results indicated that B7-2 is one of the most crucial factors in the prognosis of adult acute leukaemia and can be expected to have an important role in tumour immunity.

Long-term prognosis in childhood epilepsy: survival and seizure prognosis.

All children aged 0-19 years who had active epilepsy in a defined Swedish population were traced and given a clinical and psychometric investigation. Twelve years later, a follow-up study was carried out. Eleven of the 194 children had died, 8 of whom had had signs of neurodeficit, i.e., abnormal neurology and/or mental retardation. A long-standing remission of seizures occurred in 124 of the 194 children. Signs of neurodeficit, frequent seizures, and many types of seizures were negative prognostic factors. The presence of all these factors carried a bad prognosis, seizures persisting during 12 years in greater than 80%. For those who were mentally and neurologically normal and had low seizure frequency, prognosis was excellent, only 11% still having active epilepsy after 12 years. A study of the annual remission rate showed that each year approximately 13% of the children without neurodeficit had remission from epilepsy the next year. This rate appeared to be stable over the 12 years studied. Among those children with neurodeficit, the annual remission rate was high only during the first years after onset, later falling to 3% a year.
