PURPOSE Treatment options for patients with chronic myeloid leukemia (CML) who relapse after allogeneic bone marrow transplantation (BMT) are limited. Treatment with lymphocytes from the original marrow donor and the influence on the malignant clone was studied in these patients. PATIENTS AND METHODS Seven patients with CML that had relapsed after BMT with T-cell-depleted grafts were treated. Six patients received leukocyte infusions from the original marrow donor. One patient received a second BMT with unseparated marrow from the same sibling donor. Chimerism was studied using erythrocyte and cytogenetic markers. Residual leukemic cells were monitored by cytogenetic analysis of the Philadelphia (Ph) chromosome and by polymerase chain reaction (PCR) of the breakpoint cluster region/Abelson (BCR-ABL) fusion gene. RESULTS In five patients with hematologic relapse, the Ph chromosome disappeared 1 to 3 months after the leukocyte infusions. Cytogenetic analysis and in situ hybridization (ISH) showed only donor cells during further follow-up. Four to five patients became negative for the BCR-ABL translocation by PCR. Graft-versus-host disease (GVHD) always preceded response and was severe in two patients. One patient with cytogenetic relapse showed no response after leukocyte infusions. GVHD after second BMT was of moderate severity. One year after second BMT, PCR for the BCR-ABL translocation was negative. CONCLUSION Infusion of donor leukocytes is an effective treatment with a low mortality in patients with CML relapsed after BMT with a T-cell-depleted graft. Longer follow-up and more patients will be needed to know whether cure will be permanent.

PURPOSE We developed and validated a brief, yet sensitive, 33-item general cancer quality-of-life (QL) measure for evaluating patients receiving cancer treatment, called the Functional Assessment of Cancer Therapy (FACT) scale. METHODS AND RESULTS The five-phase validation process involved 854 patients with cancer and 15 oncology specialists. The initial pool of 370 overlapping items for breast, lung, and colorectal cancer was generated by open-ended interview with patients experienced with the symptoms of cancer and oncology professionals. Using preselected criteria, items were reduced to a 38-item general version. Factor and scaling analyses of these 38 items on 545 patients with mixed cancer diagnoses resulted in the 28-item FACT-general (FACT-G, version 2). In addition to a total score, this version produces subscale scores for physical, functional, social, and emotional well-being, as well as satisfaction with the treatment relationship. Coefficients of reliability and validity were uniformly high. The scale's ability to discriminate patients on the basis of stage of disease, performance status rating (PSR), and hospitalization status supports its sensitivity. It has also demonstrated sensitivity to change over time. Finally, the validity of measuring separate areas, or dimensions, of QL was supported by the differential responsiveness of subscales when applied to groups known to differ along the dimensions of physical, functional, social, and emotional well-being. CONCLUSION The FACT-G meets or exceeds all requirements for use in oncology clinical trials, including ease of administration, brevity, reliability, validity, and responsiveness to clinical change. Selecting it for a clinical trial adds the capability to assess the relative weight of various aspects of QL from the patient's perspective.

PURPOSE The purpose is twofold: (1) to identify the malignant glioma patients treated in a trial of hyperfractionated radiotherapy (RT) and carmustine (BCNU) who may have been eligible for a stereotactic radiosurgery (SRS) boost; and (2) to compare survival of such patients with that of those considered SRS-ineligible. PATIENTS AND METHODS From January 1983 to July 1989, 778 malignant glioma patients were enrolled on Radiation Therapy Oncology Group (RTOG) 83-02, a randomized phase I/II hyperfractionated RT dose-escalation trial with BCNU chemotherapy. The SRS criteria used in a single-institution trial were applied to these patients; they are: Karnofsky performance status (KPS) of greater than 60; well-circumscribed tumor less than 4.0 cm; no subependymal spread; and a location not adjacent to brainstem or optic chiasm. RESULTS Eighty-nine patients (11.9%) were identified as potentially SRS-eligible. The median survival times (MST) and 18-month survival rates of the 89 eligible and 643 ineligible patients were 14.4 versus 11.7 months and 40% versus 27%, respectively (P = .047). The MST and 18-month survival rate of the 544 SRS-ineligible patients with KPS greater than 60 were 12.1 months and 29%, respectively, and were not statistically inferior to the survival of the SRS-eligible group (P = .21). Multivariate analysis revealed age, KPS, and histopathology to be strongly predictive of survival, and SRS eligibility was also significantly predictive (P = .047). CONCLUSION SRS-eligible patients enrolled on RTOG 83-02 had survival superior to that of the SRS-ineligible group, and this advantage is mainly due to the selection of a subgroup with a high minimum KPS.

PURPOSE To analyze the putative relationship between immunotherapy-associated dysthyroidism and the probability of a tumor response. PATIENTS AND METHODS A total of 89 consecutive patients with advanced cancer were treated with interleukin-2 (IL2)-based immunotherapy in a prospective study. RESULTS Twenty patients developed thyroid dysfunction. Repeatedly positive tests for thyroid antibodies developed in 28% of the patients. Twenty-two patients achieved a response. There was no relationship between the formation of antibodies and the probability of response. There appeared to be a trend toward a relationship between thyroid dysfunction and response (P = .23). A strong relationship was found between response on the one hand and cumulative dose of IL2 (P = .01) and treatment duration with IL2 (P = .025) on the other. The frequency of thyroid dysfunction was also significantly correlated with treatment duration (P = .001). After adjustment for cumulative dose of IL2 and treatment duration, no relationship between thyroid dysfunction and response remained (P = .99). CONCLUSION There is no relationship between thyroid dysfunction and the probability of tumor response. Thyroid dysfunction is merely a function of treatment duration and cumulative dose of IL2.

PURPOSE To evaluate the role of serum beta 2-microglobulin (beta 2M) in the prognosis of patients with Hodgkin's disease. PATIENTS AND METHODS One hundred sixty previously untreated patients with Hodgkin's disease had serum beta 2M levels determined before initiation of treatment. Serum beta 2M was tested for its correlation with known prognostic factors for patients with Hodgkin's disease. These variables, including beta 2M, were correlated with complete remission (CR) rate and time to treatment failure (TTF). Univariate and multivariate analyses were performed. RESULTS Serum beta 2M levels greater than 2.5 mg/L were found in 29% of patients. Such elevation was more common in patients with more advanced-stage disease. Elevated serum beta 2M was an independent and powerful factor in the prediction of lower response rate and shorter TTF. Its impact appeared to be more significant in patients with advanced disease. CONCLUSION Serum beta 2M appears to correlate with tumor stage in patients with Hodgkin's disease and elevated serum levels of this polypeptide predict a less favorable prognosis.

PURPOSE We studied a multimodality approach using extrapleural pneumonectomy, chemotherapy, and radiotherapy in patients with malignant pleural mesothelioma. PATIENTS AND METHODS From 1980 to 1992, 52 selected patients, underwent treatment. Median age was 53 years (range, 33 to 69). Initial patient evaluation was performed by a multimodality team. Pathologic diagnosis was reviewed and confirmed before therapy. Patients with no medical contraindication and potentially resectable mesothelioma on computed tomography (CT) (magnetic resonance imaging [MRI] when it became available) received extrapleural pneumonectomy, cyclophosphamide, doxorubicin, and cisplatin (CAP) chemotherapy, and radiotherapy. RESULTS Perioperative morbidity and mortality rates were 17% and 5.8%, respectively. The overall median survival duration is 16 months (range, 1 month to 8 years). The 32 patients with epithelial histologic variant had 1-, 2-, and 3-year survival rates of 77%, 50%, and 42%, respectively. Patients with mixed and sarcomatous cell disease had 1- and 2-year survival rates of 45% and 7.5%; no patient lived longer than 25 months (P < .01). At resection, positive regional mediastinal lymph nodes were found in 13. Positive lymph nodes were associated with poorer survival than were negative nodes (P < .01). Patients with epithelial variant and negative mediastinal lymph nodes had a survival rate of 45% at 5 years. CONCLUSION Multimodality therapy including extrapleural pneumonectomy has acceptable morbidity and mortality for selected patients. Prolonged survival occurred in patients with epithelial histologic variant and negative mediastinal lymph nodes. These data provide a rationale for a revised staging system for malignant pleural mesothelioma; furthermore, they permit stratification of patients into groups likely to benefit from aggressive multimodality treatment.

PURPOSE Recent innovations allow the integration of microelectronics into drug packaging, providing a continuous record of the interactions of the patient with the drug package. We hypothesized that adherence to oral tamoxifen, as measured by a pressure-activated microelectronic monitoring device, would be significantly discrepant from traditional measures of patient adherence, ie, patient self-report (SR) and pill counts (PCs). PATIENTS AND METHODS Twenty-six patients receiving oral tamoxifen therapy were assessed by patient SR, PCs, and Medication Event Monitoring System (MEMS; Aprex Corp, Fremont, CA) microelectronic monitoring. A microprocessor in the MEMS cap recorded each opening as a presumptive dose, listing the date, time, and duration of opening for later retrieval on a microcomputer. Patients were not informed that their adherence was to be monitored electronically or that PCs would be performed. RESULTS A total of 2,102 days (70.1 months) of tamoxifen therapy were monitored; patients were monitored for a mean of 2.92 months of tamoxifen therapy. SR adherence to oral tamoxifen was significantly higher than that suggested by either PCs (SR missed doses only v PC, P = .008) or MEMS adherence monitoring (SR missed doses only v MEMS missed doses only, P = .005; SR dosing-interval errors only v MEMS dosing-interval errors only, P < .0001; SR all dosing errors v MEMS all dosing errors, P < .0005). PC data also suggested significantly higher adherence rates than MEMS monitoring. CONCLUSION Microelectronic adherence monitoring provides both confirmatory and complimentary data regarding adherence behavior, while also allowing for the evaluation of patterns of nonadherence. Patient SRs and PCs likely overestimate the degree to which patients adhere to their tamoxifen regimen.

PURPOSE The object of this study was to compare the relative sensitivities of morphologic, immunophenotypic, gene rearrangement, cytogenetic, and polymerase chain reaction (PCR) analyses in the detection of lymphoma cells in the bone marrow and peripheral blood of patients with follicular lymphoma. PATIENTS AND METHODS Bone marrow and peripheral-blood samples from 28 newly diagnosed patients with follicular lymphoma referred from several different medical centers were assessed. Routine morphologic assessment was performed initially and the remainder of the sample was aliquoted for DNA extraction to be used for gene rearrangement and PCR analyses and for immunophenotypic and cytogenetic analyses where a sufficient amount of sample remained. RESULTS Morphologic assessment of the bone marrow was positive for lymphoma cells in 11 of 28 patients. PCR amplification of t(14;18) breakpoint DNA detected lymphoma cells in 17 of 24 patients assessed. Morphologic assessment detected lymphoma cells in three bone marrow samples that were negative by PCR. PCR analysis was the only method able to detect circulating lymphoma cells in peripheral blood at diagnosis and was positive in 15 of 24 samples. The other methods of assessment did not show lymphoma in any samples in which lymphoma was not detected by morphologic or PCR analysis. Lymphoma cells were found in the bone marrow and/or peripheral blood as frequently in early-stage patients as in advanced-stage patients. CONCLUSION PCR amplification of t(14;18) breakpoint DNA together with morphologic assessment had the highest yield of detecting lymphoma cells in the bone marrow and/or peripheral blood of our population of newly diagnosed patients with follicular lymphoma. The clinical significance and prognostic importance of lymphoma cells detected by PCR in the bone marrow and/or peripheral blood of newly diagnosed follicular lymphoma patients awaits long-term follow-up data of these and additional patients.
Why women gain weight with adjuvant chemotherapy for breast cancer.

PURPOSE Among breast cancer patients receiving adjuvant chemotherapy, weight gain is a common side effect that may decrease quality of life and potentially threaten survival. Weight gain during treatment is a problem that is clinically well appreciated, and one that has been studied by a number of investigators. DESIGN A literature review was conducted to address each of the following issues: (1) the prevalence and magnitude of weight gain in women receiving adjuvant chemotherapy for early-stage breast cancer, (2) factors that might affect the amount of weight gained, (3) adverse consequences of weight gain, (4) mechanisms potentially responsible for weight gain, and (5) current dietary intervention programs directed toward women receiving adjuvant chemotherapy. RESULTS Weight gain is associated with a number of adverse effects in breast cancer patients receiving adjuvant chemotherapy. Weight gains are exaggerated in premenopausal women and women receiving multiagent regimens. Little research has been conducted to investigate the underlying mechanisms that contribute to weight gain in this population. CONCLUSION Interventions to prevent weight gain during adjuvant chemotherapy are underway; however, little research has been conducted to investigate the underlying mechanisms of energy imbalance. Although changes in resting metabolic rate, thermogenesis, physical activity, and dietary intake are all plausible, no firm data exist to support any of these mechanisms. There is a need for research that explores the relative contribution of each of these factors to energy imbalance, so that optimally effective interventions can be created and implemented to combat this problem.

PURPOSE The prognosis of patients with multifocal primary and early or multiple relapsed Ewing's sarcoma is poor with conventional chemoradiotherapy and surgery. We evaluated the efficacy and feasibility of a myeloablative regimen administered as consolidation treatment for these patients. PATIENTS AND METHODS The ablative regimens consisted of simultaneous radiochemotherapy: 12 Gy hyperfractionated total-body irradiation (TBI; two doses of 1.5 Gy for 4 days) plus fractionated high-dose melphalan (30 to 45 mg/m2 for 4 days) followed by high-dose etoposide (40 to 60 mg/kg) with or without carboplatin (900 to 1,500 mg/m2) (hyper-ME +/- C). These regimens were applied in a dose-escalation study that included 17 patients. All patients underwent remission induction chemotherapy and local treatment before myeloablative therapy. Seven patients had multifocal primary Ewing's sarcoma, and 10 had early or multiple relapse. We performed a matched-cohort analysis of the 17 grafted patients with 41 historic controls matched for sex, age, diagnosis, extent of disease, interval from diagnosis to transplant in the transplant group, and interval from diagnosis to relapse in the control group. RESULTS The probability of relapse in the study patients is 52% at 6 years after the last event before transplantation. In the control group, the probability of relapse at 6 years was 98%. Eight of 17 treated patients are alive in complete remission at a median observation time of 49 months (range, 19 to 76) from the last event before transplantation. Probability of relapse-free survival in the study patients is 45% +/- 12% at 6 years after the last event before transplant, compared with 2% +/- 2% for the historic control group. CONCLUSION Myeloblative therapy with hyper-ME +/- C radiochemotherapy can improve the prognosis of multifocal primary and early or multiple relapsing Ewing's sarcoma.

PURPOSE We studied a series of 283 breast cancer patients retrospectively to determine the actual benefits of axillary lymph node dissection (ALND) for these patients. PATIENTS AND METHODS The records of 283 women with invasive breast cancer treated between 1988 and 1990 were reviewed for histologic status of the axillary lymph nodes, tumor size, DNA content, hormone-receptor values, and actual adjuvant treatments received. RESULTS ALND was of possible therapeutic benefit for the 15% (43 of 283) of patients who had clinically positive nodes. Nodal metastases were found in 86% (37 of 43) of patients in this subgroup. ALND alone determined the indication for standard adjuvant therapy for a group of 31% (88 of 283) of patients who had favorable primary biopsy findings and clinically negative axillary nodes; ALND proved that 13% (11 of 88) of these latter patients had positive nodes. For 54% (152 of 283) of patients who had clinically negative nodes and unfavorable biopsies, ALND played no role in the decision as to whether standard adjuvant therapy was indicated. Only 5% (seven of 152) and 3% (four of 152) of these latter patients received radiation therapy and/or high-dose adjuvant chemotherapy, respectively, because of ALND. CONCLUSION The benefits of ALND vary greatly for different groups of breast cancer patients, and controlled studies may be needed to determine whether ALND is necessary for all breast cancer patients.

PURPOSE To determine the characteristics of patients with unilateral breast cancer who subsequently develop contralateral breast cancer (CBC), to assess their prognosis relative to patients who do not develop a CBC, and to assess the feasibility of using conservative surgery (CS) and radiotherapy (RT) to treat CBC. MATERIALS AND METHODS Of 1,624 women treated with CS and RT for unilateral stage I or II breast cancer at the Joint Center for Radiation Therapy, 77 developed an invasive CBC. Sixty-two CBCs were treated with CS and RT. The median follow-up duration was 95 months from the time of initial breast cancer diagnosis, and 63 months from CBC diagnosis. RESULTS The cumulative actuarial rate of CBC was 7.0% at 10 years, and the annual incidence rate for CBC was relatively constant. Young age predicted for CBC. When age was analyzed by decade the relative risk (RR) for older patients compared with younger patients was 0.79 (95% confidence interval [CI], 0.62 to 1.01). The presence of lobular carcinoma in situ (LCIS), higher tumor stage, and lack of adjuvant systemic therapy also predicted for CBC with borderline significance. Multivariate analyses showed that CBC was associated with a statistically significant greater likelihood of local recurrence (LR) or distant recurrence (RR, 1.68; 95% CI, 1.03 to 2.71), and distant-only recurrence (RR, 2.17; 95% CI, 1.28 to 3.69). Among assessable patients treated with bilateral RT, 28 of 31 ipsilateral and 11 of 11 contralateral breasts had an excellent or good overall cosmetic outcome at 5 years, and treatment-related complications were minimal. CONCLUSION We conclude that (1) young age is associated with a greater likelihood of CBC, (2) patients who develop a CBC have a greater subsequent risk of distant relapse as compared with patients without CBC, and (3) it is feasible to deliver sequential nonoverlapping bilateral RT without compromising the cosmetic outcome or increasing complications.
