PURPOSE To assess preferences for the content and process of genetic counseling and testing for breast-ovarian cancer susceptibility among women at high risk for breast cancer. METHODS Ninety-eight healthy women who had a family history of breast cancer in at least two first-degree relatives participated in a structured telephone survey that evaluated preferences for type of provider and the content and process of pretest education and posttest genetic counseling. RESULTS Forty-two percent of women preferred that pretest education be delivered by a genetic counselor, while 22% preferred an oncologist. This preference was positively associated with a desire to discuss psychosocial issues during the session (P = .001). For posttest counseling, 38% of women preferred an oncologist, while 20% preferred a genetic counselor. However, women who desired supportive counseling during this session were significantly more likely to prefer a genetic counselor to an oncologist (P = .02). Fewer women wished to see a primary care physician or gynecologist for pretest education (11%) or posttest counseling (22%). With regard to the counseling process, 82% of women wished to self-refer for genetic counseling, but 63% desired advice and recommendations about whether to be tested. CONCLUSION When feasible, the optimal approach may be for oncologists to work with genetic counselors to provide pretest education and medical recommendations. Elicitation of patients' preferences may be useful to determine the level of counseling services needed.

PURPOSE To compare the efficacy of sequential mechlorethamine, vincristine, procarbazine, and prednisone (MOPP) followed by doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) versus the MOPP/ABV hybrid regimen in advanced-stage Hodgkin's disease. PATIENTS AND METHODS A total of 737 patients with previously untreated stages III2A, IIIB, IVA, or IVB Hodgkin's disease and patients in first relapse after radiotherapy were prospectively randomized to sequential MOPP-ABV or MOPP/ABV hybrid. Of 691 eligible patients, 344 received the sequential regimen and 347 received the hybrid. RESULTS The overall response rate was 95%, with complete responses (CRs) in 79%: 83% on the MOPP/ABV hybrid and 75% on the sequential MOPP-ABVD arm (P = .02). With a median follow-up time of 7.3 years, the 8-year failure-free survival (FFS) rates were 64% for MOPP/ABV hybrid and 54% far sequential MOPP-ABVD (P = .01; 0.69 relative risk of failure, comparing MOPP/ABV hybrid v MOPP-ABVD). The 8-year overall survival rate was significantly better for the MOPP/ABV hybrid (79%) as compared with sequential MOPP-ABVD (71%) (P = .02; relative risk, 0.65). MOPP/ABV hybrid had significantly more life-threatening or fatal neutropenia and pulmonary toxicity than the sequential MOPP-ABVD arm, which was associated with significantly greater thrombocytopenia. Nine cases of acute myelogenous leukemia or myelodysplasia were reported on the sequential regimen as compared with only one on the hybrid (P = .01). CONCLUSION MOPP/ABV hybrid chemotherapy was significantly more effective than sequential MOPP-ABVD. FFS and overall survival were significantly improved on the hybrid arm, which was also associated with a lower incidence of acute leukemia or myelodysplasia.

PURPOSE The analogue 131I-metaiodobenzylguanidine (MIBG), which is specifically targeted to neuroblastoma cells, may provide more effective and less toxic treatment for neuroblastoma than conventional external-beam radiotherapy. We report a dose escalation study of 131I-MIBG to define dose-limiting toxicity without and with autologous bone marrow support. PATIENTS AND METHODS Thirty patients with relapsed neuroblastoma were treated in groups of six with escalating doses of 3 to 18 mCi/kg of 131I-MIBG. After rapid escalation in the first three patients treated at 3 to 6 mCi/kg, treatment was escalated in 3-mCi/kg increments from 9 to 18 mCi/kg. Autologous tumor-free bone marrow was cryopreserved in all patients receiving 12 mCi/kg and more. Toxicity and response were assessed. RESULTS Eighty percent of patients who received 12 mC/kg or more experienced grade 4 thrombocytopenia and/or neutropenia. Dose-limiting hematologic toxicity was reached at 15 mCi/kg, at which level two of five assessable patients required bone marrow reinfusion for absolute neutrophil count (ANC) of less than 200/microL for more than 2 weeks, and four of nine at the 18-mCi/kg level. Prolonged thrombocytopenia was common, with failure to become platelet-transfusion independent in nine patients. One patient with extensive prior treatment developed secondary leukemia and three became hypothyroid. Responses were seen in 37% of patients, with one complete response (CR), 10 partial response (PR), three mixed response, 10 stable disease, and six progressive disease. The minimum dose of 131I-MIBG for 10 of the 11 responders was 12 mCi/kg. CONCLUSION Treatment with 131I-MIBG has mainly hematologic toxicity, which can be abrogated with bone marrow rescue. The high response rate in refractory disease suggests that this agent may be useful in combination with myeloablative chemotherapy and autologous stem-cell rescue to improve outcome in advanced neuroblastoma.

PURPOSE To assess the results of treatment, patterns of failure, and prognostic factors for relapse in a contemporary cohort of patients with stage II seminoma. MATERIALS AND METHODS From January 1981 and December 1993, 99 patients (median age, 35 years) with stage II seminoma (IIA, 41; IIB, 28; IIC, 24; IID, six) were managed at our institution. Eighty were treated with radiation therapy (RT) and 19 with chemotherapy (ChT). RESULTS With a median follow-up of 6.7 years, the five-year overall actuarial survival was 94%, the 5-year cause-specific survival was 94%, and the 5-year relapse-free rate was 83%. Sixteen (20%) of the 80 patients treated with RT relapsed (median time to relapse, 9 months). Relapse occurred outside the irradiated area in all but two patients. Distant relapse sites included the supraclavicular fossa, bone (four patients, three with spinal cord compression), and lung/mediastinum. All 19 patients treated primarily with ChT achieved disease control and none has relapsed. The relapse rate at 5 years for patients with stage IIA to IIB was 11% (seven of 64), and 56% (nine of 16) for those with stage IIC to IID disease (P < .0001). No patient with IIC or IID disease treated with ChT relapsed as compared with 56% of patients treated with RT (0 of 14 v nine of 16, P = .002). CONCLUSION Radiation therapy is highly effective in patients with stage IIA or IIB seminoma (89% were relapse free). In stage IIC or IID disease, although local control with RT is excellent, a 50% risk of distant relapse is unacceptable, and not all patients who relapse can be salvaged. Chemotherapy should clearly be the primary treatment in patients with stage IIC or IID seminoma.

PURPOSE This study had two major goals: (1) to assess the effectiveness of a regimen of fluorouracil (5-FU) plus levamisole plus leucovorin as postoperative surgical adjuvant therapy for patients with high-risk colon cancer, and (2) to evaluate 6 months versus 12 months of chemotherapy. PATIENTS AND METHODS Patients with poor-prognosis stage II or III colon cancer were randomly assigned to receive adjuvant chemotherapy with either intensive-course 5-FU and leucovorin combined with levamisole, or a standard regimen of 5-FU plus levamisole. Patients were also randomly assigned to receive either 12 months or 6 months of chemotherapy, which resulted in four treatment groups. RESULTS Eight hundred ninety-one of 915 patients entered (97.4%) were eligible. The median follow-up duration is 5.1 years for patients still alive. There was a difference among the four treatment groups with respect to patient survival, and a significant duration-by-regimen interaction was observed. Specifically, standard 5-FU plus levamisole was inferior to 5-FU plus leucovorin plus levamisole when treatment was given for 6 months (5-year survival rate, 60% v 70%; P < .01). CONCLUSION There was no significant improvement in patient survival when chemotherapy was given for 12 months compared with 6 months. When chemotherapy was given for 6 months, standard 5-FU plus levamisole was associated with inferior patient survival compared with intensive-course 5-FU plus leucovorin plus levamisole. These data suggest that 5-FU plus levamisole for 6 months should not be used in clinical practice, whereas 6 months of treatment with 5-FU plus leucovorin plus levamisole is effective.

PURPOSE To study the clinical features and outcome for primary non-Hodgkin's lymphomas of the nose/nasopharynx (NNP-NHLs) according to immunophenotype. PATIENTS AND METHODS One hundred thirteen Chinese patients with primary NNP-NHLs that belonged to the categories E, F, G, or H according to the Working Formulation (WF), with full immunophenotypic data and complete clinical follow-up data, were analyzed in this retrospective study. RESULTS Ninety (79.6%) patients had localized (stage I or II) disease, while 23 (20.4%) had stage III or IV disease. The lymphomas in 51 (45.1%), 24 (21.3%), and 38 (33.6%) patients showed natural killer (NK)/T- (CD56-positive), T-cell, and B-cell immunophenotype, respectively. Seventy-three patients (65.8%) achieved a complete remission, of whom 34 (46.6%) subsequently relapsed. The median follow-up time for those alive was 88 months. The 5-year actuarial disease-free and overall survival rates were 34.4% and 37.9%, respectively. Multivariate analysis showed that only stage and immunophenotype were significant for survival. NK/T lymphomas were distinctive among the three immunophenotypes in the following aspects: the highest male-to-female ratio, more frequent involvement of the nasal cavity alone, higher risk of dissemination to the skin, more frequent development of hemophagocytic syndrome, and the worst prognosis (overall median survival, 12.5 months). CONCLUSION The three immunophenotypes studied are shown to exhibit different clinical patterns. Since the NK/T phenotype carries the worst prognosis, patients who present with NNP-NHL should have their tumors analyzed for CD56 expression.

PURPOSE We conducted a multicenter study of differentiation therapy with all-trans retinoic acid (ATRA) followed by intensive chemotherapy in patients with newly diagnosed acute promyelocytic leukemia (APL) and analyzed the prognostic factors for predicting complete remission (CR), event-free survival (EFS), and disease-free survival (DFS). PATIENTS AND METHODS All patients received ATRA until CR. If patients had an initial leukocyte count greater than 3.0 x 10(9)/L, they received daunorubicin (DNR) and behenoyl cytarabine (BHAC). During therapy, if patients showed blast and promyelocyte counts greater than 1.0 x 10(9)/L, they received additional DNR and BHAC. After achieving CR, patients received three courses of consolidation and six courses of maintenance/intensification chemotherapy. RESULTS Of 198 registered, 196 were assessable (age range, 15 to 86 years; median, 46) and 173 (88%) achieved CR. Multivariate analysis showed that no or minor purpura at diagnosis (P = .0046) and age less than 30 years (P = .0076) were favorable factors for achievement of CR. Predicted 4-year overall survival and EFS rates were 74% and 54%, respectively, and the 4-year predicted DFS rate for 173 CR patients was 62%. Multivariate analysis showed that age less than 30 years (P = .0003) and initial leukocyte count less than 10 x 10(9)/L (P = .0296) were prognostic factors for longer EFS, and initial leukocyte count less than 10.0 x 10(9)/L was a sole significant prognostic factor for longer DFS (P = .0001). CONCLUSION Our results show that age, hemorrhagic diathesis, and initial leukocyte count are prognostic factors for APL treated with ATRA followed by intensive chemotherapy.

PURPOSE We conducted a randomized trial to evaluate primarily the cardioprotective effect of dexrazoxane (DEX) in patients with advanced breast cancer and soft tissue sarcomas (STS) treated with high-dose epirubicin (EPI). We wished also to determine the value of radioimmunoscintigraphy (RIS) in the assessment of anthracycline cardiotoxicity. PATIENTS AND METHODS Patients with breast cancer (n = 95) or STS (n = 34) received EPI 160 mg/m2 by intravenous (I.V.) bolus every 3 weeks with or without DEX 1,000 mg/m2 I.V. Cardiac monitoring included multigated radionuclide (MUGA) scans with determination of resting left ventricular ejection fraction (LVEF), and RIS with indium 111 antimyosin monoclonal antibodies. RESULTS In either disease, antitumor response rates, time to progression, and survival did not significantly differ between the two arms. There was little difference in noncardiac toxicity for the two treatment groups. All methods of cardiac evaluation clearly documented the cardioprotective effect of DEX. Four patients developed congestive heart failure (CHF), all in the EPI arm. The decrease in LVEF from baseline was significantly greater in the control group. An abnormal antimyosin uptake was observed early in both arms and progressively increased during treatment. However, this increase was significantly higher in the EPI group (P = .004). CONCLUSION DEX significantly protects against the development of cardiotoxicity when high single doses of EPI are used. Apparently, there was no evidence of an adverse impact of DEX on antitumor activity. Although RIS is a sensitive technique in detecting anthracycline cardiac damage, its specificity is low and it cannot be considered a primary test for guiding anthracycline treatment.

PURPOSE To investigate whether cytogenetic clonal evolution can be suppressed with interferon alfa (IFN-alpha) therapy in patients with chronic myelogenous leukemia (CML). PATIENTS AND METHODS Ninety patients with CML and cytogenetic clonal evolution who received IFN-alpha-based regimens were analyzed. Clonal evolution was defined as the presence of karyotypic abnormalities in addition to the Philadelphia (Ph) chromosome. Patients were evaluated for the suppression of cytogenetic clonal evolution after therapy, the cytogenetic response, and survival. RESULTS The median age of the population was 39 years (range, 15 to 70 years), median time from diagnosis to clonal evolution 14 months (range, 0 to 145 months), and median percentage of abnormal metaphases 18% (range, 4% to 100%). Fifty six patients (62%) achieved some suppression of cytogenetic clonal evolution; in 41 patients (46%), the suppression was complete. The overall median survival was 51 months, with 43% alive at 5 years. Patients who achieved a complete suppression of cytogenetic clonal evolution had a median survival of 66 months, with 51% alive at 5 years. Characteristics associated with a better response include a lower percentage of abnormal metaphases, time to cytogenetic clonal evolution of 24 months or less, and absence of other features of accelerated disease. A prognostic classification for cytogenetic clonal evolution defined three groups with complete response (CR) rates of 85%, 34%, and 0% (P < .0001) and median survival times of 58, 31, and 30 months, respectively (P=.02). CONCLUSION Patients with cytogenetic clonal evolution can respond to IFN-alpha therapy, and this response is associated with longer survival. A previously described prognostic model separates patients into subsets with different probabilities of response to IFN-alpha and survival.

PURPOSE Prior studies show that increased levels of the DNA repair protein O6 methylguanine-DNA methyltransferase (MGMT), also referred to as O6-alkylguanine-DNA alkyltransferase (AGT) correlate with the resistance of glioma cell lines to nitrosoureas. The observed nitrosourea sensitivity of MGMT-deficient lines (methyl excision repair negative [MER-]) and those repair-proficient lines pretreated with MGMT-specific inhibitors (eg, O6 benzylguanine) has raised the possibility that tumor MGMT levels may be an important predictor of survival in patients with gliomas. PATIENTS AND METHODS We correlated the MGMT level in malignant astrocytoma tissues, obtained from patients treated with radiotherapy and bis-chloroethylnitrosourea (BCNU) on a prior prospective trial (Southwest Oncology Group [SWOG] 8737), with overall and failure-free survival. RESULTS Of 64 assessable patients with malignant astrocytoma (63% glioblastoma, 37% anaplastic astrocytoma), 64% had high (> 60,000 molecules/nucleus) MGMT levels. The overall median survival for patients with high versus low MGMT levels was 8 and 29 months, respectively (P=.0002), and median failure-free survival 3 and 6 months, respectively (P=.008). Subset analysis by histology (high v low MGMT levels) for anaplastic astrocytoma was 14 versus 62 months (n=24) and for glioblastoma was 7 versus 12 months (n=40). The overall hazards ratio (risk for death) for high versus low MGMT levels was 3.41; in young patients, the hazards ratio was higher (age 18 to 40 years, 4.19; age 41 to 60 years, 3.08) but became equal by MGMT level at age older than 60 years (1.11). Multivariate analysis showed that MGMT was independent of other known prognostic factors (age, performance status, histology). CONCLUSION The MGMT level in tumor tissue specimens may be a predictive marker of survival in patients with malignant astrocytoma that is independent of other previously described prognostic variables.

PURPOSE To evaluate the efficacy and safety of docetaxel in patients with paclitaxel-resistant metastatic breast cancer (MBC). PATIENTS AND METHODS Docetaxel (100 mg/m2) was administered every 3 weeks to 46 patients registered at four centers. Patients had previously received < or = two chemotherapy regimens for MBC. All patients had progressive disease while receiving paclitaxel therapy. Treatment was repeated until there was evidence of disease progression or for a maximum of three cycles after best response. RESULTS Objective responses were seen in eight of 44 assessable patients (18.1%; 95% confidence interval [CI], 6.7% to 29.5%). Seven patients had partial responses and one patient responded completely. Response rates were not significantly different by previously received paclitaxel dose or resistance. No responses were seen in 12 patients who had previously received paclitaxel by 24-hour infusion, but the response rate in 32 patients who had received paclitaxel by 1- to 3-hour infusion was 25%. The median response duration was 29 weeks and the median time to disease progression was 10 weeks. Median survival was 10.5 months. Clinically significant (severe) adverse events included neutropenic fever (24% of patients), asthenia (22%), infection (13%), stomatitis (9%), neurosensory changes (7%), myalgia (7%), and diarrhea (7%). CONCLUSION Docetaxel is active in patients with paclitaxel-resistant breast cancer, particularly in those who failed to respond to brief infusions of paclitaxel. Response rates were comparable to or better than those seen with other therapies for patients with paclitaxel-resistant MBC. This confirms preclinical studies, which indicated only partial cross-resistance between paclitaxel and docetaxel.
