To reduce doxorubicin, bleomycin, vinblastine and dacarbazine toxicity, the Cancer and Leukemia Group B conducted a phase 2 trial of doxorubicin, vinblastine, and gemcitabine for newly diagnosed, nonbulky stages I and II Hodgkin lymphoma. Ninety-nine assessable patients received 6 cycles of doxorubicin 25 mg/m2, vinblastine 6 mg/m2, and gemcitabine 800 mg/m2 (1000 mg/m2 in first 6) on days 1 and 15 every 28 days. Computed tomography (CT) and positron emission tomography (PET) were performed before and after 2 and 6 cycles. Complete remission (CR)/CR unconfirmed was achieved in 72 of 99 patients (72.7%) and partial remission in 24 of 99 patients (24.2%). The CR rate was 81% when using PET criteria. Two patients have died of Hodgkin lymphoma progression. Median follow-up for nonprogressing patients is 3.3 years. The progression-free survival (PFS) at 3 years was 77% (95% confidence interval, 68%-84%). The relapse rate was less than 10% for patients with favorable prognostic factors. The 2-year PFS for cycle 2 PET-negative and-positive patients was 88% and 54%, respectively (P =.0009), compared with 89% and 27% for cycle 6 PET-negative and-positive patients (P =.0001). Although the CR rate and PFS were lower than anticipated, patients with favorable prognostic features had a low rate of relapse. Cycle 2 PET and cycle 6 PET were predictive of PFS. This clinical trial is registered at www.clinicaltrials.gov as #NCT00086801. © 2011 by The American Society of Hematology.

Previous studies have suggested that BRCA-related epithelial ovarian cancer (EOC) conveys improved survival compared with that of sporadic EOC, but few studies have evaluated differences between BRCA genotypes. We compared characteristics and outcome by genotype in BRCA-associated EOC. Patients with BRCA-associated EOC who were diagnosed between January 30,1981, and December 30, 2008, were retrospectively identified through institutional review board-approved registry studies. We examined clinical characteristics, including event-free survival (EFS) and overall survival (OS), for BRCA1 versus BRCA2 patients. We identified 197 cases (148 BRCA1 cases; 49 BRCA2 cases); the median follow-up period was 63 months. BRCA2 patients were older (55.4 vs. 51.1 y; P < 0.01) and had fewer poorly differentiated tumors (67% vs. 82%; P < 0.05). No difference in EFS was observed. OS at 5 years was 75% in BRCA2 patients versus 61% in BRCA1 patients; this was not statistically significant. A non-significant trend toward improved OS was observed in BRCA2 patients with advanced-stage disease (hazard ratio = 0.59; 95% confidence interval 0.32-1.08). Age and grade differed significantly between BRCA1 and BRCA2 carriers in our study population. Whereas no overall differences in EFS or OS were observed, there was a trend toward improved OS in BRCA2 carriers with advanced-stage disease. This may reflect important differences between BRCA genotypes and should be validated in larger studies. © 2012 Elsevier Inc.
