RESUMO

This study examined associations between HPV status and weight change in oropharyngeal cancer (OPC). OPC patients receiving concurrent chemoradiotherapy in Toronto, Canada were included. Relationships were assessed between HPV status and weight loss grade (WLG, combining weight loss and current body mass index); weight change during treatment; and HPV status and WLG/weight change on overall (OS) and cancer-specific (CSS) survival. Of 717 patients, WLG pre-radiation was less severe among HPV-positive compared to HPV-negative, though weight loss during treatment was greater. The adjusted odds ratio for greater WLG among HPV-positive versus HPV-negative was 0.47 (95%CI 0.28-0.78). Grade-4 WLG (worst category) experienced poorer OS and CSS (OS adjusted hazard ratio (aHR) 4.08; 95%CI 1.48-11.2, compared to Grade-0); and was non-significant for HPV-negative (aHR 2.34; 95%CI 0.69-7.95). Relationships between weight change before/during treatment and survival had similar direction between HPV-positive and HPV-negative, but of greater magnitude in HPV-positive patients.

RESUMO

BACKGROUND: To investigate the relationship between attendance to a pre-treatment psychoeducational intervention (prehab) with treatment outcomes and toxicities in patients receiving radiotherapy for head and neck cancers (HNCs). METHODS: Patients were included from prehab inception in 2013 to 2017, comparing overall survival (OS), locoregional recurrence-free survival (LRFS), and locoregional recurrence (LRR) between prehab attendees (PA) and non-attendees (PNA). Multivariable analysis was performed for OS and LRFS. RESULTS: Among 864 PA and 1128 PNA, 2-year OS was 88% vs 80% (p < 0.001), and LRFS was 84% vs 75% (p < 0.001). On multivariable analysis (MVA), OS and LRFS were independently and unfavourably associated with PNA. The PA cohort had a lower frequency of a "rocky treatment course" compared with the PNA cohort (52/150, 35% vs 71/150, 47%; p = 0.034). CONCLUSIONS: Prehab at our institution is associated with improved long-term oncologic outcomes. Prospective data is needed to better understand this association.
