ABSTRACT

BACKGROUND: Brentuximab vedotin in combination with doxorubicin, vinblastine, and dacarbazine (AVD) is approved in the upfront setting for advanced stage classical Hodgkin lymphoma (cHL). People living with HIV have been excluded from these studies. We aimed to understand the activity and safety of brentuximab vedotin-AVD in people living with HIV diagnosed with Hodgkin lymphoma, while focusing on HIV disease parameters and antiretroviral therapy (ART) interactions. METHODS: We present the phase 2 portion of a multicentre phase 1/2 study. Eligible patients were 18 years or older, had untreated stage II-IV HIV-associated cHL (HIV-cHL), a Karnofsky performance status of more than 30%, a CD4+ T-cell count of 50 cells per µL or more, were required to take ART, and were not on strong CYP3A4 or P-glycoprotein inhibitors. Patients were treated intravenously with 1·2 mg/kg of brentuximab vedotin (recommended phase 2 dose) with standard doses of AVD for six cycles on days 1 and 15 of a 28-day cycle. The primary endpoint of the phase 2 portion was 2-year progression-free survival (PFS), assessed in all eligible participants who began treatment. Accrual has been completed. This trial is registered at ClinicalTrials.gov, NCT01771107. FINDINGS: Between March 8, 2013, and March 7, 2019, 41 patients received study therapy with a median follow up of 29 months (IQR 16-38). 34 (83%) of 41 patients presented with stage III-IV and seven (17%) with stage II unfavourable HIV-cHL. 37 (90%) of 41 patients completed therapy, all 37 of whom achieved complete response. The 2-year PFS was 87% (95% CI 71-94) and the overall survival was 92% (78-97). The most common grade 3 or worse adverse events were peripheral sensory neuropathy (four [10%] of 41 patients), neutropenia (18 [44%]), and febrile neutropenia (five [12%]). One treatment-related death was reported, due to infection. INTERPRETATION: Brentuximab vedotin-AVD was highly active and had a tolerable adverse event rate in HIV-cHL and is an important therapeutic option for people with HIV-cHL. The complete reponse rate is encouraging and is possibly related to a unique aspect of HIV-cHL biology. Upcoming 5-year data will evaluate the sustainability of the outcomes obtained. FUNDING: National Institutes of Health and National Cancer Institute.

ABSTRACT

OBJECTIVES: Rural women are underrepresented in cancer research. We hypothesized that providing access to a research study to rural, medically underserved women who were receiving their breast cancer screening using a mobile mammography unit would increase the representation of rural women in a cancer cohort study. DESIGN: This study is a cross-sectional study using a cohort of women who have been recruited to a breast cancer study in Arkansas. SETTING: Recruiters accompanied a mobile mammography unit, the MammoVan, to implement a novel method for reaching and recruiting underrepresented rural Arkansas women into the study. Participants include 5850 women recruited from 2010 through 2012 as part of the Arkansas Rural Community Health (ARCH) study. RESULTS: Participants recruited during their mammography screening on the MammoVan tended to be more rural, less educated, and more likely to be non-Hispanic than those recruited in other venues. A significant difference was not noted for race or age. CONCLUSION: Collaboration with the MammoVan greatly aided the recruitment of rural participants. These strategies can facilitate the representation of this historically underserved and understudied rural population in future research studies.

ABSTRACT

INTRODUCTION: Vorinostat (VOR), a histone deacetylase inhibitor, enhances the anti-tumor effects of rituximab (R) and cytotoxic chemotherapy, induces viral lytic expression and cell killing in Epstein-Barr virus-positive (EBV+) or human herpesvirus-8-positive (HHV-8+) tumors, and reactivates latent human immunodeficiency virus (HIV) for possible eradication by combination antiretroviral therapy (cART). PATIENTS AND METHODS: We performed a phase I trial of VOR given with R-based infusional EPOCH (etoposide, prednisone, vincristine, cyclophosphamide, and doxorubicin hydrochloride) (n = 12) and cART in aggressive HIV-associated B-cell non-Hodgkin lymphoma (NHL) in order to identify safe dosing and schedule. VOR (300 or 400 mg) was given orally on days 1 to 5 with each cycle of R-EPOCH for 10 high-risk patients with diffuse large B-cell lymphoma (1 EBV+), 1 EBV+/HHV-8+ primary effusion lymphoma, and 1 unclassifiable NHL. VOR was escalated from 300 to 400 mg using a standard 3 + 3 design based on dose-limiting toxicity observed in cycle 1 of R-EPOCH. RESULTS: The recommended phase II dose of VOR was 300 mg, with dose-limiting toxicity in 2 of 6 patients at 400 mg (grade 4 thrombocytopenia, grade 4 neutropenia), and 1 of 6 treated at 300 mg (grade 4 sepsis from tooth abscess). Neither VOR, nor cART regimen, significantly altered chemotherapy steady-state concentrations. VOR chemotherapy did not negatively impact CD4+ cell counts or HIV viral loads, which decreased or remained undetectable in most patients during treatment. The response rate in high-risk patients with NHL treated with VOR(R)-EPOCH was 100% (complete 83% and partial 17%) with a 1-year event-free survival of 83% (95% confidence interval, 51.6%-97.9%). CONCLUSION: VOR combined with R-EPOCH was tolerable and seemingly efficacious in patients with aggressive HIV-NHL.

ABSTRACT

BACKGROUND: Acute leukemia of ambiguous lineage (ALAL) is a rare leukemia with sparse data availability about the survival and management strategies in elderly patients. METHODS: We used the Surveillance Epidemiology and End Results (SEER)-Medicare database to describe the overall survival (OS) and treatment pattern of elderly patients (age > 65 years) with ALAL. OS analysis was done using the Kaplan-Meier method, and its determinants were analyzed using the Cox proportional hazard regression method with a significant P < .05. RESULTS: We included 705 patients with ALAL and a median age of 80 years. The 2-year OS was 16.4% for patients aged 66 to 70 years, 8.1% for patients aged 71 to 75 years, 5.5% for patients aged 76 to 80 years, and 3.7% for patients aged > 80 years (P < .01). Two-year OS did not significantly vary by race or gender. Among the study cohort, 151 patients received chemotherapy. Two-year OS was 17% in the chemotherapy group and 3% in the no-chemotherapy group (P < .001). On multivariate analysis, age less than 80 years (Age 66-70 years: hazard ratio [HR]; 0.66, 95% confidence interval [CI], 0.52-0.85; age 71-75 years: HR, 0.80; 95% CI, 0.65-0.99; age 76-80 years: HR, 0.80; 95% CI, 0.66-0.98; P = .004) and chemotherapy (HR, 0.51; 95% CI, 0.42-0.62; P = .001) significantly reduced the hazard for mortality. CONCLUSION: Our study suggests that the OS of elderly patients with ALAL remains poor. Although treatment improved the OS, only 21.5% of patients received therapy. The optimal choice of therapy needs to be determined by prospective studies.

ABSTRACT

PURPOSE: We recently reported an association between the bother and severity of lower urinary tract symptoms secondary to benign prostatic hyperplasia and the severity of sleep disturbance. However, few studies have examined whether alterations in the severity of urinary symptoms influence the degree of sleep problems over time. MATERIALS AND METHODS: The severity of lower urinary tract symptoms in men enrolled in CAMUS (Complementary and Alternative Medicine for Urological Symptoms), a clinical trial of saw palmetto (Serenoa repens), was evaluated using AUASI (American Urological Association symptom index) and quality of life scores. Sleep disturbance was evaluated by the Jenkins sleep scale at 0, 24, 48 and 72 weeks. Statistical analyses were used to assess the relationship(s) between changes in lower urinary tract symptoms and sleep disturbance. RESULTS: The baseline characteristics of the 339 men (172 placebo arm and 167 saw palmetto arm) enrolled in the CAMUS trial with assessment of sleep disturbance and urinary symptoms were similar. There were no differences between improvements in the severity of sleep disturbance or urinary symptoms between the 2 experimental arms. Combined analyses of the entire cohort revealed significant associations (p <0.001) between the AUASI score and sleep disturbance severity with time. Multivariate analyses demonstrated that improvements in lower urinary tract symptoms other than nocturia were the most significant predictors of improvements in sleep disturbance. Specific analyses adjusting for other baseline characteristics demonstrated that a 3-point improvement in AUASI score was associated with a 0.73-point improvement in the Jenkins sleep scale with time. CONCLUSIONS: Improvements in lower urinary tract symptoms correlate with changes in sleeping abilities with time in men with benign prostatic hyperplasia. While nocturia is significantly associated with sleep disturbance, other changes in overall lower urinary tract symptoms are better predictors of changes in sleep dysfunction.
