Published: February 2017

PURPOSE: Some women may try to cope with breast cancer by making lifestyle modifications, possibly in the hope of improving disease outcome. We assessed extent, predictors, and effect on psychological distress of dietary changes in the year after diagnosis among 250 women with newly diagnosed, nonmetastatic breast cancer.PATIENTS AND METHODS: Data came from medical records, and from interviews 3 days and 12 months after initial treatment.RESULTS: At 12 months, 41% (n = 103) reported dietary changes at some time since diagnosis, with decreases in meat (77%) and increases in fruit and vegetable intake (72%) being the most frequent. Women reporting changes were more likely to be younger, to have positive nodes, to be receiving adjuvant therapy, and to be more distressed initially. The mean 0 to 12 month decrease in psychological distress was greater in women who reported changes (9 points) than those who did not (4.7 points) (P = .03), although regression toward the mean cannot be excluded.CONCLUSION: A sizable proportion of women made dietary changes on their own initiative. Most changes reported were generally consistent with current scientific hypotheses about dietary changes that might favorably affect prognosis. The profile of women reporting changes suggests a group with more concerns about recurrence, who may have initiated dietary change to help cope with and gain a sense of control over the disease, and possibly to improve prognosis. Our results suggest that newly diagnosed women could be receptive to explicit attention to diet as part of psychosocial care. However, this interest in dietary change may not, as yet, have been maximally channeled into trying to improve the care and quality of life of women facing diagnosis, treatments, and fears about recurrence.

PURPOSE: To assess the risk of fatal and nonfatal myocardial infarction (MI) after breast-conserving surgery (BCS) and radiation therapy (RT) for left-sided breast cancer. PATIENTS AND METHODS: A hospital-based retrospective cohort linkage study of all breast cancer patients registered at the Princess Margaret Hospital (PMH), Toronto, Canada, between 1982 and 1988 who were treated with postlumpectomy RT was performed. Available identifiers for the study cohort were linked to two province-wide health files: the Canadian Institute for Health Information Hospitalization File and the Ontario Mortality Database. Admissions to hospital for MI and deaths attributable to MI were identified. The relevant original health records were abstracted to verify the diagnosis of MI according to diagnostic criteria used in the World Health Organization multinational monitoring of trends and determinants in cardiovascular disease (MONICA) project. We compared incidence of MI in the study cohort with the general population and incidence of MI after therapy for left- versus right-sided breast cancer. RESULTS: A cohort of 2,128 patients was identified. The median length of follow-up was 10.2 years. The incidence of MI in the study cohort was comparable to that in an age-matched general population of women in Ontario. There were 70 coronary events among 56 patients after breast irradiation. According to MONICA criteria, 53 and six events were characterized as definite and possible MIs, respectively. Eleven events did not satisfy MONICA criteria for MI. Twenty-six patients treated for left-sided and 23 patients treated for right-sided breast cancer experienced at least one definite or possible MI (log-rank test, P = .66). There were eight fatal MIs among the left-sided group and six among the right-sided group. There was no excess of other cardiac diseases among patients who received left-sided radiotherapy compared to the right-sided group. CONCLUSION: We have found no evidence for excess morbidity and mortality from coronary artery disease among women treated with RT to the left breast after BCS at 10.2 years of follow-up. Longer follow-up is required to confirm that excess cardiac disease has been completely avoided.

Published: February 2017

PURPOSE: To study distribution and toxicity of cytolytic T lymphocytes (CTLs) against a single melanoma epitope.PATIENTS AND METHODS: CD8+T cells obtained by leukapheresis from 10 patients with disseminated HLA-A2.1+, tyrosinase-positive melanomas were immunized in vitro against tyrosinase369-377(YMNGTMSQV). Drosophila cells transduced with HLA-A2.1, CD80, and CD54 (intracellular adhesion molecule-1) were used for priming, followed by two rounds of immunization with mononuclear cells as antigen-presenting cells. 1 × 108CTL were infused intravenously (IV) on day 1. CTL frequency was measured by limiting dilutions in five patients.111In labeling and scintigraphy measured distribution of CTL in next five. Five days later, 1 × 108CTLs were infused on 4 successive days to both groups. Immunohistology of response was judged by biopsies.RESULTS: Infusions were nontoxic. CTLs were undetectable in the blood, going to lungs within 5 minutes. At 4, 24, and 72 hours, they were found in liver and spleen. Lesions were visualized by scintiscans in one responding patient where two subcutaneous nodules were noted at 4 and 24 hours. A second patient had a partial response and remains alive with disease 2 years later. CD8+T cells were found in lesions of responders, associated with the presence of HLA-A2 molecules and tyrosinase. Two nonresponders without tyrosinase and HLA-A2 molecules had a paucity of CD8+T cells in their lesions. Whether the CD8+T cells in lesions of responders were those we had reinfused is uncertain.CONCLUSION: CTLs immunized against a single melanoma epitope were nontoxic but did not specifically localize to tumor sites. Nevertheless, two patients had disease regression. Additional therapeutic studies with specifically immunized CTL seem justified.

PURPOSE: Investigation of minimal residual disease (MRD) in childhood acute lymphoblastic leukemia (ALL) using molecular markers has proven superior to other standard criteria (age, sex, and WBC) in distinguishing patients at high, intermediate, and low risk of relapse. The aim of our study was to determine whether MRD investigation is valuable in predicting outcome in Philadelphia-negative adult patients with ALL. PATIENTS AND METHODS: MRD was assessed in 85 adult patients with B-lineage ALL by semiquantitative immunoglobulin H gene analysis on bone marrow samples collected during four time bands in the first 24 months of treatment. Fifty patients received chemotherapy only and 35 patients received allogeneic (n = 19) or autologous (n = 16) bone marrow transplantation (BMT) in first clinical remission. The relationship between MRD status and clinical outcome was investigated and compared with age, sex, immunophenotype, and presenting WBC count. RESULTS: Fisher’s exact test established a statistically significant concordance between MRD results and clinical outcome at all times. Disease-free survival (DFS) rates for MRD-positive and -negative patients and log-rank testing established that MRD positivity was associated with increased relapse rates at all times (P < .05) but was most significant at 3 to 5 months after induction and beyond. MRD status after allogeneic BMT rather than before was found to be an important predictor of outcome in 19 adult patients with ALL tested. In patients receiving autologous BMT (n = 16), the MRD status before BMT was more significant (P = .005). CONCLUSION: The association of MRD test results and DFS was independent of and greater than other standard predictors of outcome and is therefore important in determining treatment for individual patients.

PURPOSE: To determine the dose-limiting toxicities, maximum-tolerated dose, and pharmacokinetics of intravenous estramustine phosphate (IV EMP). PATIENTS AND METHODS: A total of 31 patients with hormone-refractory prostate cancer received IV EMP as a 30- to 90-minute infusion weekly (n = 28) or for 3 consecutive days followed by a single weekly dose (n = 3). IV EMP dose was escalated from 500 to 3,000 mg/m2. Pharmacokinetics of EMP and the metabolites estramustine (EaM), estromustine (EoM), estradiol, and estrone were assessed after weeks 1 and 4 of treatment. RESULTS: The initial IV EMP infusion caused perineal discomfort that was ameliorated by lengthening the infusion time. Other common toxicities were grade 1 to 2 hepatotoxicity, nausea or vomiting, and fatigue or malaise. Lower-extremity thrombosis occurred in one patient, and two others developed upper-extremity thrombosis associated with venous infusion catheters. Dose-limiting fatigue and hypotension occurred at 3,000 mg/m2, and cumulative fatigue developed after multiple cycles at 2,500 mg/m2. Mean EMP clearance, estimated steady-state volume of distribution, and elimination half-life were 3.7 L/h, 10.6 L, and 3.7 hours, respectively. Variability of EMP clearance was 21%, and variation in area under the curve per dose for the metabolites was 28% to 36%. Elimination half-lives of EoM and EaM were 110 hours and 64 hours, and peak plasma concentrations of these active metabolites exceeded 10 μmol/L after IV EMP doses ≥ 2,000 mg/m2. CONCLUSION: High-dose IV EMP can be administered safely as a weekly short infusion to patients with HRPC. High peak concentrations of active metabolites after IV EMP may provide an advantage over oral EMP in antimicrotubule drug combinations.

PURPOSE: We present the Royal Marsden Hospital experience of cerebral metastases from primary epithelial ovarian carcinoma (EOC) over the last 20 years and examine the evidence for an increasing incidence of EOC metastasizing to this site. PATIENTS AND METHODS: A total of 3,690 women with EOC were seen at the Royal Marsden Hospital from 1980 to 2000. Eighteen of these patients developed cerebral metastases. RESULTS: Median age at diagnosis of EOC was 52 years (range, 39 to 67). All patients received at least one line of platinum-based chemotherapy; 56% (10 of 18) received more than one line of treatment; 17% (three of 18), two lines; 11% (two of 18), three lines; and 28% (five of 18), four lines. The median treatment interval between each line of chemotherapy was 12, 18, and 4 months. The median interval between diagnosis and CNS relapse was 46 months (range, 12 to 113), in comparison with 5 and 7.5 months for hematogenous relapse in lung or liver, respectively (P < .001). The incidence of CNS metastases in our population from 1980 to 1984 was 0.2%; from 1985 to 1989, 0%; from 1990 to 1994, 0.3%; and from 1995 to 1999, 1.3% (P < .001). An analysis of data from the literature also suggests that the incidence of cerebral metastases from EOC has increased over time. CONCLUSION: CNS metastases in EOC are a rare and late manifestation of the disease, occurring in patients with a prolonged survival caused by repeated chemosensitive relapses. An analysis of our data and the data from the literature suggests that the incidence of metastasis at this site in patients with EOC is increasing.

Published: February 2017

PURPOSE: The relationship between germ-line mutations of hMSH2 and hMLH1, microsatellite instability (MSI), and loss of DNA mismatch repair (MMR) gene expression were studied to formulate an effective selection protocol for patients with suspected hereditary nonpolyposis colorectal cancer who should be offered genetic testing. PATIENTS AND METHODS: Patients eligible for germ-line analysis of hMLH1 and hMSH2 were selected. Tumor specimens were obtained to assess MSI and loss of MMR gene expression. RESULTS: Among 37 patients who participated in the study, two hMSH2 and two hMLH1 missense mutations (11%) were detected, none of which was found in a panel of 60 healthy volunteers. High MSI was found in five tumors (19%) and low MSI in 10 tumors (39%); 12 tumors (46%) were microsatellite stable. Four tumors demonstrated loss of hMLH1, and three tumors demonstrated loss of hMSH2 protein expression. CONCLUSION: No relationship was found between MMR gene mutations and MSI; low or no MSI was found in the four patients with germ-line mutations, and none of the five patients with high MSI demonstrated abnormalities of MMR genes. On the contrary, loss of hMLH1 or hMSH2 expression was found in the tumors from three of the four patients demonstrating germ-line mutations. These data suggest that germ-line mutations of the MMR gene can occur in people with MSI-negative tumors. Sensitive clinical criteria and the study of MMR gene expression may be useful to identify this subset of patients.

PURPOSE: To prospectively determine the impact of genetic counseling and testing on risk-reduction strategies and cancer incidence in a cohort of individuals at hereditary risk for breast and ovarian cancer. PATIENTS AND METHODS: Two hundred fifty-one individuals with BRCA mutations were identified at a single comprehensive cancer center from May 1, 1995, through October 31, 2000. Uniform recommendations regarding screening and preventive surgery were provided in the context of genetic counseling. Patients were followed for a mean of 24.8 months (range, 1.6 to 66.0 months) using standardized questionnaires, chart reviews, and contact with primary physicians. RESULTS: Frequency of cancer surveillance by physical examinations and imaging studies increased after genetic counseling and testing. Twenty-one breast, ovarian, primary peritoneal, or fallopian tube cancers were detected after receipt of genetic test results. Among 29 individuals choosing risk-reducing mastectomy after testing, two were found to have occult intraductal breast cancers. Among 90 individuals who underwent risk-reducing salpingo-oophorectomy, one early-stage ovarian neoplasm and one early-stage fallopian tube neoplasm were found. Radiographic or tumor marker–based screening detected six breast cancers, five of which were stage 0/I, one early-stage primary peritoneal cancer, and three stage I or II ovarian cancers. Six additional breast cancers were detected by physical examination between radiographic screening intervals; four of these six tumors were stage I. No stage III or stage IV malignancies were detected after genetic testing. CONCLUSION: This study provides prospective evidence that genetic counseling and testing increased surveillance and led to risk-reducing operations, which resulted in diagnosis of early-stage tumors in patients with BRCA1 and BRCA2 mutations.

PURPOSE: We present our experience with relapsed and recently diagnosed patients with high-risk multiple myeloma (MM) receiving immunosuppressive, nonmyeloablative melphalan (MEL)-based conditioning regimens (mini-allograft). PATIENTS AND METHODS: Thirty-one MM patients received allografts from HLA-matched siblings (n = 25) or unrelated donors (n = 6) using a mini-allograft. Seventeen had progressive disease (PD) and 14 had responsive disease (RD) (six with primary RD and eight with responsive relapse). Thirty patients had received one (n = 13) or two or more (n = 17) prior autologous transplantations (ATs). Median age was 56 years (range, 38 to 69 years). Twenty-one patients had chromosome 13 abnormality. Two patients were hemodialysis dependent. Blood and bone marrow grafts were administered to 28 and three patients, respectively. Donor lymphocyte infusions were given to 18 patients either to attain full donor chimerism (n = 6) or to eradicate residual disease (n = 12). RESULTS: By day 100, 25 (89%) of 28 patients were full donor chimeras, one was a mixed chimera, and two had autologous reconstitution. Acute graft-versus-host disease (GVHD) developed in 18 patients (58%), and 10 progressed to chronic GVHD (limited in six and extensive in four). At a median follow-up of 6 months, 19 (61%) of 31 patients achieved complete/near complete remission. Twelve patients (39%) have died: three of PD, three of early treatment-related mortality (TRM) (before day 100), and six of late TRM. Median overall survival (OS) was 15 months. At 1 year, there was a significantly longer event-free survival (86% v 31%, P = .01) and OS (86% v 48%, P = .04) when a mini-allograft was performed after one versus two or more prior ATs, respectively. When compared with historical MM controls (n = 93) receiving conventional allografts, early TRM was significantly lower (10% v 29%, P = .03), and OS at 1 year was better (71% v 45%; P = .08) in the mini-allograft MM patients. CONCLUSION: Mini-allograft induced excellent disease control in MM patients with high-risk disease, but is still associated with a significant GVHD.

PURPOSE: Previously, we developed a novel biochemotherapy regimen combining interferon alfa-2b with fluorouracil and cisplatin (FAP). We now report the results of a prospective randomized trial comparing FAP with methotrexate, vinblastine, doxorubicin, and cisplatin (M-VAC), the standard chemotherapy regimen for locally advanced and metastatic urothelial cancer. The purpose of this study was to compare the response rates and overall survival of patients with metastatic or unresectable urothelial cancer treated with these two chemotherapy regimens. PATIENTS AND METHODS: Between October 1992 and September 1999, 172 previously untreated patients were registered and randomly assigned to treatment with either FAP or M-VAC. Patients were followed until their death. RESULTS: The pretreatment clinical characteristics of the groups were similar except for sex (P < .01). Sex did not affect prognosis or survival. The objective response rate for patients assigned to FAP was 42% (35 of 83 patients), with complete response observed in eight (10%) of 83 patients. Among the patients assigned to M-VAC, 51 (59%) of 86 had an objective response, with complete response observed in 21 (24%) of 86. The Kaplan-Meier estimate of median survival was 12.5 months for both groups. Both regimens were quite toxic, with more mucocutaneous toxicity in the FAP arm and more myelosuppression in the M-VAC arm. CONCLUSION: Although overall survival was not significantly different, patients assigned to M-VAC had a much better chance of responding to front-line therapy. Thus, FAP is very likely to be inferior to M-VAC and is certainly no less toxic. FAP cannot be recommended as part of the standard armamentarium for urothelial cancer.

PURPOSE: Temozolomide is a novel oral alkylating agent with demonstrated efficacy as second-line therapy for patients with recurrent anaplastic astrocytoma and glioblastoma multiforme (GBM). This phase II study was performed to determine the safety, tolerability, and efficacy of concomitant radiation plus temozolomide therapy followed by adjuvant temozolomide therapy in patients with newly diagnosed GBM. PATIENTS AND METHODS: Sixty-four patients were enrolled onto this open-label, phase II trial. Temozolomide (75 mg/m2/d × 7 d/wk for 6 weeks) was administered orally concomitant with fractionated radiotherapy (60 Gy total dose: 2 Gy × 5 d/wk for 6 weeks) followed by temozolomide monotherapy (200 mg/m2/d × 5 days, every 28 days for six cycles). The primary end points were safety and tolerability, and the secondary end point was overall survival. RESULTS: Concomitant radiation plus temozolomide therapy was safe and well tolerated. Nonhematologic toxicities were rare and mild to moderate in severity. During the concomitant treatment phase, grade 3 or 4 neutropenia, thrombocytopenia, or both were observed in 6% of patients, including two severe infections with Pneumocystis carinii. During adjuvant temozolomide, 2% and 6% of cycles were associated with grade 3 and 4 neutropenia or thrombocytopenia, respectively. Median survival was 16 months, and the 1- and 2-year survival rates were 58% and 31%, respectively. Patients younger than 50 years old and patients who underwent debulking surgery had the best survival outcome. CONCLUSION: Continuous daily temozolomide and concomitant radiation is safe. This regimen of concomitant chemoradiotherapy followed by adjuvant chemotherapy may prolong the survival of patients with glioblastoma. Further investigation is warranted, and a randomized trial is ongoing.
