The effect of retention on the relapse of Class II Division 1 cases.

Sixty cases of Class II Division 1 malocclusion were studied; 30 of them had been retained after the completion of orthodontic treatment, the other 30 had not and acted as a control group. Using measurements from lateral skull radiographs and statistical analysis, the two groups were compared in respect of skeletal pattern, soft tissue, overjet, overbite and interincisal angle. Both the retained and the non-retained group showed a tendency to relapse after the completion of active treatment; a tendency to relapse even while in retention was observed. The relapse in overjet was found to be more significant than the relapse in overbite. In both groups the relapse in overjet was found to be associated with the size of the original overjet, the overbite at the end of active treatment and the interincisal angle at the end of active treatment. In both groups the relapse in overbite was found to be associated with the size of the original overbite, the change in maxillary-mandibular planes angle and the interincisal angle at the end of active treatment.

Studies of FLT3 mutations in paired presentation and relapse samples from patients with acute myeloid leukemia: implications for the role of FLT3 mutations in leukemogenesis, minimal residual disease detection, and possible therapy with FLT3 inhibitors.

FLT3 mutations, either internal tandem duplications (ITDs) or aspartate residue 835 (D835) point mutations, are present in approximately one third of patients with acute myeloid leukemia (AML) and have been associated with an increased relapse rate. We have studied FLT3 mutations in paired presentation and relapse samples to ascertain the biology of these mutations and to evaluate whether they can be used as markers of minimal residual disease. At diagnosis, 24 patients were wild-type FLT3, and 4 acquired a FLT3 mutation at relapse (2 D835(+), 2 ITD(+)), with a further patient acquiring an ITD at second relapse. Of 20 patients positive at diagnosis (18 ITD(+), 2 D835(+)), 5 who were all originally ITD(+) had no detectable mutation at relapse, as determined by a sensitive radioactive polymerase chain reaction. One of these patients had acquired an N-Ras mutation not detectable at presentation. Furthermore, another patient had a completely different ITD at relapse, which could not be detected in the presentation sample. These results indicate that FLT3 mutations are secondary events in leukemogenesis, are unstable, and thus should be used cautiously for the detection of minimal residual disease.

Clonal evolution and lack of cytogenetic response are adverse prognostic factors for hematologic relapse of chronic phase CML patients treated with imatinib mesylate.

We followed 141 patients treated with imatinib mesylate (> 300 mg) for chronicphase chronic myelogenous leukemia (CML) following failure of treatment with interferon. During 12 months from the start of imatinib mesylate treatment, 96.5% achieved a complete hematologic response, 47.0% achieved a major cytogenetic response, and 32.4% achieved a complete cytogenetic response. The proportion of patients with hematologic relapse was 10.9% at 12 months and 14.6% at 18 months. In a univariate Cox regression analysis, the only pretreatment characteristics that correlated with an increased risk of hematologic relapse were hemoglobin level less than 120 g/L (12 g/dL) (P =.02), increased bands in the peripheral blood (P =.01), and clonal evolution (P <.0001). In a multivariate analysis, an elevated platelet count (P =.03) and clonal evolution (P <.0001) were the only significant factors for hematologic relapse. During treatment, the absence of a major cytogenetic response within the first 6 months also significantly correlated with relapse (P =.03). Notably, patients failing to achieve a major cytogenetic response by 6 months had a significantly higher rate of hematologic relapse (27%) compared with those who achieved a major cytogenetic response by 6 months (3%), and patients with clonal evolution had a significantly higher risk of hematologic relapse (50%) than those without clonal evolution (9%).

Low dendritic cell count after allogeneic hematopoietic stem cell transplantation predicts relapse, death, and acute graft-versus-host disease.

Dendritic cells (DCs) are key antigen-presenting cells with a potential role in tumor vaccines. We investigated the hypothesis that early reconstitution of DCs after allogeneic hematopoietic stem cell transplantation (SCT) improves survival. We also correlated DC reconstitution with complications of relapse and acute graft-versus-host disease (aGVHD). Fifty patients underwent transplantation between February 2000 and March 2003, with a median follow-up of 501 days (range, 136-1263 days). Most (92%) received blood stem cells, and the remainder received bone marrow from HLA-matched sibling donors for predominantly high-risk hematologic malignancies. Around the time of engraftment, peripheral blood underwent flow cytometry analysis for DCs, and the cells were divided as DC1 and DC2. Using Kaplan-Meier analysis, patients with lower DC counts (< 4.97 cells/microL) were found to have significantly worse survival (P =.002), increased incidence of relapse (P =.002), higher incidence of aGVHD onset (P =.0005), and a composite end point of relapse or death (P =.0017). A Cox proportional hazards multivariate model adjusted for important covariates confirmed that low DC count is independently associated with death (hazard ratio [HR], 3.8; P =.02), time to relapse (HR, 11.6; P =.001), and aGVHD (HR, 3.3; P =.04). Sensitivity and specificity rates for low DC count in predicting death or relapse are 73% and 75%, respectively. Low numbers of circulating DCs significantly increase the risk for relapse and acute GVHD and predict death after allogeneic SCT.

High frequency of immunophenotype changes in acute myeloid leukemia at relapse: implications for residual disease detection (Cancer and Leukemia Group B Study 8361).

Multiparameter flow cytometry (MFC) has the potential to allow for sensitive and specific monitoring of residual disease (RD) in acute myeloid leukemia (AML). The use of MFC for RD monitoring assumes that AML cells identified by their immunophenotype at diagnosis can be detected during remission and at relapse. AML cells from 136 patients were immunophenotyped by MFC at diagnosis and at first relapse using 9 panels of 3 monoclonal antibodies. Immunophenotype changes occurred in 124 patients (91%); they consisted of gains or losses of discrete leukemia cell populations resolved by MFC (42 patients) and gains or losses of antigens on leukemia cell populations present at both time points (108 patients). Antigen expression defining unusual phenotypes changed frequently: CD13, CD33, and CD34, absent at diagnosis in 3, 33, and 47 cases, respectively, were gained at relapse in 2 (67%), 15 (45%), and 17 (36%); CD56, CD19, and CD14, present at diagnosis in 5, 16, and 20 cases, were lost at relapse in 2 (40%), 6 (38%), and 8 (40%). Leukemia cell gates created in pretreatment samples using each 3-antibody panel allowed identification of relapse AML cells in only 68% to 91% of cases, but use of 8 3-antibody panels, which included antibodies to a total of 16 antigens, allowed identification of relapse AML cells in all cases. Thus, the immunophenotype of AML cells is markedly unstable; nevertheless, despite this instability, MFC has the potential to identify RD in AML if multiple antibody panels are used at all time points.

A randomized controlled trial to prevent glycemic relapse in longitudinal diabetes care: study protocol (NCT00362193).

BACKGROUND: Diabetes is a common disease with self-management a key aspect of care. Large prospective trials have shown that maintaining glycated hemoglobin less than 7% greatly reduces complications but translating this level of control into everyday clinical practice can be difficult. Intensive improvement programs are successful in attaining control in patients with type 2 diabetes, however, many patients experience glycemic relapse once returned to routine care. This early relapse is, in part, due to decreased adherence in self-management behaviors. OBJECTIVE: This paper describes the design of the Glycemic Relapse Prevention study. The purpose of this study is to determine the optimal frequency of maintenance intervention needed to prevent glycemic relapse. The primary endpoint is glycemic relapse, which is defined as glycated hemoglobin greater than 8% and an increase of 1% from baseline. METHODS: The intervention consists of telephonic contact by a nurse practitioner with a referral to a dietitian if indicated. This intervention was designed to provide early identification of self-care problems, understanding the rationale behind the self-care lapse and problem solve to find a negotiated solution. A total of 164 patients were randomized to routine care (least intensive), routine care with phone contact every three months (moderate intensity) or routine care with phone contact every month (most intensive). CONCLUSION: The baseline patient characteristics are similar across the treatment arms. Intervention fidelity analysis showed excellent reproducibility. This study will provide insight into the important but poorly understood area of glycemic relapse prevention.

The Nithsdale schizophrenia surveys. XI: Relatives' expressed emotion. Stability over five years and its relation to relapse.

The level of expressed emotion (EE) in 32 relationships between relatives and schizophrenic patients was assessed on three separate occasions over five years. EE was high on all three occasions in 25% of relatives, low on all three in 38%, and fluctuating in 38%; that is, in the majority of relatives (63%) the level of EE was stable over time. Three relatives who had previously shown high EE had evidence of dementia at the time of the third assessment, and showed low EE. Fourteen patients relapsed at least once over five years; patients who relapsed were evenly spread throughout those living in a home in which EE was consistently high, consistently low, or fluctuating. However, patients living in low-EE homes who did relapse did so significantly less often than those who relapsed and were living in homes in which EE was high or fluctuating. At the time of relapse, EE was not consistently high, and some patients in consistently high-EE homes did not relapse at all over five years.

Relapse prevention in bipolar I disorder: 18-month comparison of olanzapine plus mood stabiliser v. mood stabiliser alone.

BACKGROUND: Few controlled studies have examined the use of atypical antipsychotic drugs for prevention of relapse in patients with bipolar I disorder. Aims To evaluate whether olanzapine plus either lithium or valproate reduces the rate of relapse, compared with lithium or valproate alone. METHOD: Patients achieving syndromic remission after 6 weeks'treatment with olanzapine plus either lithium (0.6-1.2 mmol/l) or valproate (50-125 microg/ml) received lithium or valproate plus either olanzapine 5-20 mg/day (combination therapy) or placebo (monotherapy), and were followed in a double-masked trial for 18 months. RESULTS: The treatment difference in time to relapse into either mania or depression was not significant for syndromic relapse (median time to relapse: combination therapy 94 days, monotherapy 40.5 days; P=0.742), but was significant for symptomatic relapse (combination therapy 163 days, monotherapy 42 days; P=0.023). CONCLUSIONS: Patients taking olanzapine added to lithium or valproate experienced sustained symptomatic remission, but not syndromic remission, for longer than those receiving lithium or valproate monotherapy.

Duloxetine in the prevention of relapse of major depressive disorder: double-blind placebo-controlled study.

BACKGROUND: Relapse rates may be as high as 50% in people with major depressive disorder (MDD) previously treated to remission. AIMS: Duloxetine, an inhibitor of serotonin and noradrenaline reuptake that is licensed in Europe, the USA and elsewhere for the treatment of depressive episodes, was evaluated with regard to its efficacy, safety and tolerability in the prevention of relapse of MDD. METHOD: Adult out-patients with MDD received duloxetine (60 mg daily) for 12 weeks (n=533). Patients who responded to the drug were then randomised to duloxetine(60 mg daily)(n=136) or or placebo placebo (n=142) for 26 weeks. The primary measure of efficacy was time to relapse. RESULTS: Patients who received duloxetine (60 mg daily) experienced significantly longer times to relapse of MDD, and better efficacy, global well-being, and quality-of-life outcomes compared with patients who received placebo. It should be noted that adverse events which occur in discontinuation may mimic some signs of depressive relapse, and were not specifically elicited in this study. CONCLUSIONS: Duloxetine (60 mg daily) is effective in the prevention of relapse of MDD during continuation treatment.

Psychotic symptom and cannabis relapse in recent-onset psychosis. Prospective study.

BACKGROUND: Cannabis use appears to exacerbate psychotic symptoms and increase risk of psychotic relapse. However, the relative contribution of cannabis use compared with other risk factors is unclear. The influence of psychotic symptoms on cannabis use has received little attention. AIMS: To examine the influence of cannabis use on psychotic symptom relapse and the influence of psychotic symptom severity on relapse in cannabis use in the 6 months following hospital admission. METHOD: At baseline, 84 participants with recent-onset psychosis were assessed and 81 were followed up weekly for 6 months, using telephone and face-to-face interviews. RESULTS: A higher frequency of cannabis use was predictive of psychotic relapse, after controlling for medication adherence, other substance use and duration of untreated psychosis. An increase in psychotic symptoms was predictive of relapse to cannabis use, and medication adherence reduced cannabis relapse risk. CONCLUSIONS: The relationship between cannabis use and psychosis may be bidirectional, highlighting the need for early intervention programmes to target cannabis use and psychotic symptom severity in this population.

Childhood Hodgkin's disease: patterns of relapse.

One hundred seventy-nine consecutive children with Hodgkin's disease seen at Stanford University Medical Center between the years 1961-1980 have been analyzed for survival and freedom-from-relapse as a function of clinical versus laparotomy staging as well as primary treatment modalities. Of laparotomy-staged patients, 86% are alive at 10 years after primary radiation with chemotherapy reserved for relapse, as compared with 90% managed by planned combined modality therapy (p = 0.62). Patients who were clinically staged and managed with primary radiation have only a 69% survival (p = 0.05). A favorable subgroup of patients with lymphocyte-predominant Hodgkin's disease experienced a low relapse rate regardless of primary treatment modality. Patterns of relapse in clinically staged patients reflect understaging, with most relapses in distant, nonirradiated sites, whereas the less frequent relapses in laparotomy-staged patients usually reflect regional recurrence. It is concluded that laparotomy staging is highly desirable to allow greatest flexibility in optimizing individual therapy. Routine combined modality treatment for all patients would overtreat certain favorable subgroups, who can be managed more conservatively as long as the information derived from surgical staging is available. For young children, in whom bone growth issues are paramount, combined modality treatment using low-dose radiation is recommended. For older children and adolescents, where concerns over chemotherapy-related leukemogenesis and infertility are more important than height considerations, radiation alone may be used for stages I-IIIA with equal overall success.

Successful reinduction of patients with acute lymphoblastic leukemia who relapse following bone marrow transplantation.

At the present time, there is limited information on the outcome of patients with acute lymphoblastic leukemia (ALL) who relapse after bone marrow transplantation (BMT). Intuitively, it might be expected that leukemia recurring after BMT would be refractory to further treatment. In an attempt to improve survival in patients with ALL who relapse after BMT, we used standard chemotherapy for reinduction and maintenance. Of 65 patients who relapsed following allogeneic, autologous, or syngeneic BMT, 12 elected to receive no further chemotherapy, and their median survival from relapse was 36 days (range 13 to 167 days). The 53 patients who received therapy had a significantly longer median survival of 168 days (range 18 days to 4.7 years). With multidrug induction regimens there were 29 of 52 (56%) complete remissions. Six patients are currently alive, with two off therapy. In the patients who received therapy, the following factors were independent predictors of prolonged survival: longer time from BMT to relapse; younger age at diagnosis; and the use of a preparative regimen containing fractionated total body irradiation. In conclusion, leukemia recurring after BMT remains sensitive to standard therapy in many patients. We recommend that patients with ALL who relapse after BMT receive reinduction and maintenance therapy as additional good quality survival time is achieved in patients who attain a remission.

Radiotherapy with curative intent: an option in selected patients relapsing after chemotherapy for advanced Hodgkin's disease.

Thirteen patients who had relapsed or failed to obtain a complete remission after combination chemotherapy for the treatment of advanced Hodgkin's disease were treated with subtotal or total lymphoid irradiation with curative intent. Twelve of the 13 patients achieved a complete response (CR). Five of the 12 CRs subsequently relapsed at 3, 9, 9, 12, and 19 months. One patient died of leukemia 11 months following radiotherapy. The actuarial relapse-free survival at 1 year was 60%, and six patients (50%) remain disease-free with a median follow-up of 34 months (range, 10 to 115 months) following the completion of radiotherapy. Patients who failed to obtain a CR to their initial chemotherapy, whose chemotherapy CR was of short duration, or who relapsed initially in extranodal sites, tended to have a worse outcome with radiotherapy. Patients who had long disease-free intervals after initial chemotherapy or relapsed only in nodal sites tended to do relatively well. Radiation therapy was well tolerated with no major toxicity. Potentially curative radiation therapy should be considered an option in the management of selected patients who relapse following combination chemotherapy for advanced Hodgkin's disease.

Disease relapse in patients with stage I nonseminomatous germ cell tumor of the testis on active surveillance.

Thirty-six patients with apparent stage I nonseminomatous germ cell tumor (NSGCT) of the testis were treated by inguinal orchidectomy and intensive follow-up only. Assessment included measurement of serum alpha fetoprotein (alpha FP) and beta human chorionic gonadotropin (beta HCG) (tumor markers) and chest x-ray monthly for 1 year, then twice monthly for 1 year, with computed tomographic (CT) scans of abdomen and chest repeated three times monthly for the first year and six times monthly for the second year. Median follow-up was 36 months (range, 14 to 92 months). Relapse occurred in 12 patients (33.3%) at a median of 7 months (range, 2 to 28 months). Elevated markers were of limited importance in relapse detection, confirming the need for close clinical and radiological follow-up. Of nine histological factors examined in the primary tumor only the presence of lymphatic invasion was associated with a significantly higher relapse rate. All patients were treated at relapse with cisplatin-based chemotherapy. Four underwent surgery in addition, two before and two after chemotherapy. Eleven were rendered disease-free, but four had a second relapse. One patient has died, one is alive with disease, and ten are disease-free. Chemotherapy failed to cure six patients who had relapsed but bulk of disease was not a factor. Despite the good overall result reported here, optimal postorchidectomy management of apparent stage I disease remains to be defined.

Patterns of relapse in large-cell lymphoma patients with bulk disease: implications for the use of adjuvant radiation therapy.

In patients with large-cell lymphoma (LCL) treated with combination chemotherapy, the presence of bulk disease has consistently been associated with a poorer response rate and a shortened survival. The optimal therapy for patients with bulk disease (greater than or equal to 10 cm) will depend on whether treatment failures result from inadequate tumor eradication in prior bulk sites or from distant dissemination. To address this issue, we have evaluated patterns of relapse in patients with bulk disease who relapsed after achieving a complete remission with methotrexate, bleomycin, doxorubicin, cyclophosphamide, vincristine, and dexamethasone (M- or m-BACOD). Eighty-one II, III, or IV patients with disease greater than or equal to 10 cm were identified; 45 of the 81 patients achieved a confirmed complete response (CR) and are included in the analysis. The 45 complete responders included 21 patients with localized (stage II) disease and 24 patients with advanced (stage III/IV) disease. Six of the 21 stage II complete responders and three of the 24 stage II/IV complete responders also received adjuvant radiation therapy following completion of M- or m-BACOD. Only one of the 21 patients with stage II disease relapsed, doing so in the site of prior bulk involvement. In contrast, nine of 24 patients with stage III/IV disease relapsed, although no patient failed solely in the site of prior bulk disease. Stage III/IV patients recurred in either a new site (one patient), a new and old site (five), an old non-bulk site (two), or both old non-bulk and bulk sites (one). These results indicate that advanced-stage bulk-disease patients do not consistently relapse in sites of prior bulk disease; therefore, this group of patients is unlikely to benefit from adjuvant radiation therapy administered following completion of combination chemotherapy. Although the low relapse rate and the addition of adjuvant radiation therapy in a subgroup of the stage II bulk-disease patients precludes a definitive analysis, our results further suggest that these patients may be effectively treated with combination chemotherapy alone.

Phase II study of cytarabine and etoposide in children with refractory or relapsed non-Hodgkin's lymphoma: a study of the French Society of Pediatric Oncology.

Twenty-five children or adolescents with relapsed or refractory non-Hodgkin's lymphoma (NHL) were included in this phase II study of the combination of cytarabine (ARA-C) 50 mg/m2/d by 12 hours continuous infusion day 1 to day 5, ARA-C 3 g/m2/d in 3 hours day 1 to day 4, and etoposide (VP 16) 200 mg/m2 daily from day 1 to day 4. Twelve patients had B-cell, 12 T-cell, and one non-T, non-B-cell lymphoma; according to Murphy's staging system, 15 had stage III and nine stage IV disease with bone marrow involvement at diagnosis. All had previously received ARA-C by push or continuous infusion. Two patients had received epipodophyllotoxins. At the time of the study, three children had initial refractory disease, 18 were in first relapse (14 on therapy), two in first refractory relapse, and two in second relapse (on therapy). The overall response rate (RR) was 60%: eight complete responses (CRs), seven partial responses (PRs) (two became CRs after a second course). The RR was 66% (four CRs plus four PRs) in B-cell and 54% (four CRs, three PRs) in non-B-cell NHL. It was 20% (one PR per five patients) in initial or relapsed refractory disease. In four patients with measurable CNS disease, there were three CRs. Duration of response was nonassessable since all the responding patients received high-dose polychemotherapy followed by autologous bone marrow transplantation (ABMT) (five are alive with long follow-up [FU]). Toxicity was marked mostly by pancytopenia for 2 weeks, and half the patients encountered a grade-3 infection. One severe diarrhea was observed. In conclusion, high-dose ARA-C (HD-ARA-C) and VP 16 are an effective regimen in relapsed NHL, especially with CNS disease, and its toxicity is acceptable with regards to the prognosis of the disease.

Allogeneic marrow transplantation during untreated first relapse of acute myeloid leukemia.

PURPOSE: The purpose of this report was to review the Seattle experience in bone marrow transplantation (BMT) for acute myeloid leukemia (AML) during untreated first relapse. PATIENTS AND METHODS: Through 1990, 126 patients were transplanted during untreated first relapse of AML. Several preparative regimens were used, two of which involved more than 20 patients. Regimen 1 (29 patients) consisted of cyclophosphamide (CY) 120 mg/kg and 15.75 Gy of fractionated total-body irradiation (TBI) with methotrexate (MTX) given intermittently during a 102-day period to prevent graft-versus-host disease (GVHD). Regimen 2 (22 patients) consisted of the same CY and TBI treatment and a combination of MTX and cyclosporine (CSP) for GVHD prophylaxis. The remaining 75 patients were treated with 17 other transplant regimens. Outcome was compared for patients who were treated with regimen 1, regimen 2, and any other regimen. RESULTS: The 5-year probabilities of relapse-free survival (RFS), relapse, and nonrelapse mortality for 126 patients were .23, .57, and .44, respectively. With regimen 1, relapse (.26) was significantly less than for regimen 2 (.70; P = .004) or any other regimen (.76; P = .004). Regimen 1 patients developed more acute GVHD (.67) than regimen 2 patients (.26; P = .02) or patients on other regimens (.41; P = .02), and had increased nonrelapse mortality. Nevertheless, regimen 1 patients had a significantly higher 3-year RFS (.38) than those treated with regimen 2 (.18; P = .04) or any other regimen (.20; P = .05). CONCLUSIONS: For patients who received 120 mg/kg CY and 15.75 Gy TBI, relapse incidence was less and survival was better after GVHD prophylaxis with MTX alone than after a combination of MTX and CSP, despite a significantly higher incidence of acute GVHD. The results of treatment with regimen 1 justify future studies of the optimal timing of allogeneic BMT in the treatment of patients with AML.

Accelerated hyperfractionated total-lymphoid irradiation, high-dose chemotherapy, and autologous bone marrow transplantation for refractory and relapsing patients with Hodgkin's disease.

PURPOSE: To evaluate the feasibility and therapeutic effect of accelerated hyperfractionated total-lymphoid irradiation (TLI), high-dose chemotherapy, and autologous bone marrow transplantation (AuBMT) in patients with relapsing or chemotherapy-resistant Hodgkin's disease (HD). PATIENTS AND METHODS: Forty-seven patients with HD who either relapsed after chemotherapy (n = 19), or failed to respond (n = 28) to at least two regimens of combination chemotherapy were studied. No patient received prior radiation therapy (RT). Treatment started with reinduction with standard-dose chemotherapy, followed by involved-field irradiation (15 Gy) to areas of relapsed or persistent disease and TLI (20.04 Gy given in 1.67 Gy fractions three times per day for 4 days). Subsequently, patients received etoposide and high-dose cyclophosphamide, followed by infusion of unpurged autologous bone marrow. All surviving patients had a minimum follow-up duration of 1 year. The median follow-up duration for survivors was 40+ months, and the maximum follow-up duration was 80+ months. RESULTS: Of the 47 patients treated, eight (17%) died of toxicity during the peritransplant period. Twenty-nine of the remaining 39 assessable patients (74%) attained a complete response (CR), while 10 remained with residual disease and progressed early after AuBMT. Four of the CR patients (14%) relapsed and 25 patients remained alive and free of disease. The actuarial disease-free survival (DFS) rate for the entire group at 6.5 years was 50%. Patients who received the protocol for relapsing HD had a significantly better DFS rate (79%) compared with patients treated for continuous refractory disease (DFS, 33%; P < .03). CONCLUSION: Previously unirradiated patients with relapsing or chemotherapy-resistant HD who have exhausted conventional chemotherapy may still respond to an aggressive therapeutic approach consisting of accelerated hyperfractionated TLI, high-dose chemotherapy, and AuBMT rescue. This program offers a potential for long-term DFS to approximately one half of patients who would otherwise have a dismal prognosis with standard-dose salvage therapy.
