Association of Obesity With Breast Cancer Outcome in Relation to Cancer Subtypes: A Meta-Analysis.

BACKGROUND: Obesity at breast cancer (BC) diagnosis has been associated with poor outcome, although the magnitude of effect in different BC subtypes is uncertain. We report on the association of obesity or overweight at diagnosis of nonmetastatic BC with disease-free (DFS) and overall survival (OS) in the following defined subtypes: hormone receptor positive/HER2 negative (HR+HER2-), HER2 positive (HER2+), and triple negative (TNBC). METHODS: We searched MEDLINE, EMBASE, and COCHRANE databases up to January 1, 2019. Study eligibility was performed independently by 2 authors. Studies reporting hazard ratios (HRs) of OS and/or DFS for obesity or overweight in BC subtypes were included. The pooled hazard ratio was computed and weighted using generic inverse variance and random effects models. RESULTS: Twenty-seven studies were included. Obese compared with nonobese women had worse DFS in all subtypes: the hazard ratios were 1.26 (95% confidence interval [CI] = 1.13 to 1.41, P < .001) for HR+HER2- BC, 1.16 (95% CI = 1.06 to 1.26, P < .001) for HER2+ BC, and 1.17 (95% CI = 1.06 to 1.29, P = .001) for TNBC. OS was also worse in obese vs nonobese women (HR+HER2- BC HR = 1.39, 95% CI = 1.20 to 1.62, P < .001; HER2+ BC HR = 1.18, 95% CI = 1.05 to 1.33, P = .006; and TNBC HR = 1.32, 95% CI = 1.13 to 1.53, P < .001). As opposed to obesity, overweight was not associated with either DFS or OS in HER2+ BC (HR = 1.02, 95% CI = 0.81 to 1.28, P = .85; and HR = 0.96, 95% CI = 0.76 to 1.21, P = .99, respectively) or TNBC (HR = 1.04, 95% CI = 0.93 to 1.18, P = .49; and HR = 1.08, 95% CI = 0.81 to 1.44, P = .17), respectively. In HR+HER2- BC, being overweight was associated with worse OS (HR = 1.14, 95% CI = 1.07 to 1.22, P < .001). CONCLUSIONS: Obesity was associated with modestly worse DFS and OS in all BC subtypes.

Systemic Therapy Use and Outcomes After Relapse from Preoperative Radiation and Extrapleural Pneumonectomy for Malignant Pleural Mesothelioma.

BACKGROUND: Multimodality therapy with preoperative radiation (RT) followed by extrapleural pneumonectomy (EP) for patients with operable malignant pleural mesothelioma (MPM) has demonstrated encouraging results. At relapse, there are few data on the tolerance and efficacy of systemic therapies after prior multimodality therapy. MATERIALS AND METHODS: We conducted a retrospective analysis of patients with relapsed MPM after RT and EPP ± adjuvant chemotherapy to determine overall survival (OS; date of relapse to death) and the proportion of patients that received systemic therapy and associated response rate (RR). OS was estimated using Kaplan-Meier method and potential prognostic variables were examined. RESULTS: Fifty-three patients were included (2008-2016). Median OS was 4.8 months (median follow-up 4.4 months, range 0.03-34.8). Eastern Cooperative Oncology Group (ECOG) performance status (PS) ≥2, disease-free interval (DFI) <1 year, and hemoglobin ≤110 g/L at recurrence were associated with worse prognosis. Thirty-six percent of patients received any systemic therapy, whereas it was omitted in 62% because of poor PS. RR was 15% (0 complete responses, 15% partial responses) in 13 individuals with response-evaluable disease. Therapy was discontinued because of toxicity (6/15) or disease progression (5/15), and median number of cycles was four. CONCLUSION: Patients with relapsed MPM following RT and EPP, especially those with ECOG PS ≥2, DFI <1 year, and hemoglobin ≤110 g/L at recurrence, have poor prognosis and low RR to first-line systemic therapy. Earlier detection and novel diagnostic markers of relapse as well as potential neoadjuvant or adjuvant systemic therapy should be investigated in future studies. IMPLICATIONS FOR PRACTICE: The results of this study have reinforced the importance of careful selection of appropriate candidates for this combined-modality approach and favor prompt detection of recurrence with early and regular postoperative imaging and biopsy of suspected relapsed disease along with rapid initiation of systemic therapy even in patients with very low burden of disease. Furthermore, with the emergence of new systemic agents targeting different histological subtypes of malignant pleural mesothelioma, histological sampling of recurrence could inform therapeutic decisions in the future.

Sexual health in long-term breast cancer survivors.

PURPOSE: Sexual dysfunction is reported in women with breast cancer (BC). It is unclear whether symptoms persist over time as data comparing long-term survivors to controls are lacking. We compared sexual functioning in long-term breast cancer survivors (BCS) to controls and determined the impact of adjuvant therapy on sexual health. METHODS: A cohort of women with localized BC (1989-1996) was prospectively followed. BCS and controls (2005-2007) completed self-reported questionnaires. Sexual health was measured with the Sexual Activity Questionnaire (SAQ). Vasomotor, gynecological, and bladder symptoms were scored using the Menopausal Symptom Scale. Regression analysis was used to compare groups, with adjustment for age and secondly menopausal status. RESULTS: BCS (n = 248, 87%) and controls (n = 159, 95%) completed the SAQ at a median time from diagnosis of 12.5 years. BCS were older (62 vs 59 years, p = 0.0004) and more likely to be menopausal (94 vs 86%, p = 0.0025). Sexual activity did not differ significantly between BCS and controls, but when adjusted for menopausal status, pre/peri-menopausal BCS were less likely to be sexually active than pre/peri-controls (odds ratio OR 0.12, p = 0.012). In those sexually active, no significant differences were noted on the SAQ Pleasure, Discomfort, and Habit scales. BCS reported worse gynecological symptoms and pre/peri-menopausal patients had more bladder complaints (standardized effect size 0.36 p = 0.002 and 1.11, p = 0.011). Adjuvant treatments were not significantly associated with sexual function, but BCS treated with chemotherapy reported worse gynecological symptoms. CONCLUSION: Sexual health and uro-genital symptom counseling should be provided to BCS, particularly pre/peri-menopausal patients, even at long-term follow-up.
