Background: Obesity, classified by body mass index (BMI), is associated with higher postmenopausal breast cancer (BCa) risk. Yet, the associations between abdominal visceral (VAT) and subcutaneous adipose tissue (SAT) with BCa are unclear.

Methods: We assessed BCa associations with abdominal VAT and SAT in a prospective cohort of postmenopausal women without a history of cancer and with 27 years follow-up (N = 9950), during which all new cancers were adjudicated.

Background: Older adults with cancer are at an increased risk of treatment related toxicities and early death. Routinely collected clinico-demographic characteristics inadequately explain this increased risk limiting accurate prognostication. Prior studies have suggested that altered body composition and frailty are independently associated with worse survival among older adults with cancer; however, their combined influence remains unclear.

Objective: We examined associations among changes in anthropometry, regional adiposity, and inflammatory markers in Black and White women participating in intentional weight loss.

Methods: A total of 104 women with BMI ≥ 25 kg/m self-selected bariatric surgery (n = 66) or a diet and exercise program (n = 38). Anthropometric, dual-energy x-ray absorptiometry-quantified regional adiposity, and inflammatory markers (C-reactive protein [CRP], tumor necrosis factor α [TNF-α], soluble TNF receptor I [sTNFRI], sTNFRII, interleukin [IL]-6, and soluble IL-1 receptor antagonist) were measured at baseline and 6 months.

Background: Chemotherapy-induced peripheral neuropathy (CIPN) is a common and dose-limiting chemotoxicity caused by oxaliplatin. This study investigated the relationship between dietary quality and the development of moderate and/or severe CIPN in colon cancer survivors using data from the Focus on Reducing Dose-Limiting Toxicities in Colon Cancer with Resistance Exercise trial (ClinicalTrials.gov identifier NCT03291951).

Background: A plant-based diet is associated with better survival among patients with nonmetastatic colorectal cancer (CRC), but its association in metastatic CRC is unknown.

Methods: Using an National Cancer Institute-sponsored trial (CALGB/SWOG 80405), we included 1284 patients who completed validated food frequency questionnaires at the initiation of metastatic CRC treatment. We calculated 3 indices: overall plant-based diet index (PDI), which emphasized consumption of all plant foods while reducing animal food intake; healthful plant-based diet index (hPDI), which emphasized consumption of healthful plant foods such as whole grains, fruits, and vegetables; and unhealthful plant-based diet index (uPDI), which emphasized consumption of less healthful plant foods such as fruit juices, refined grains, and sugar-sweetened beverages.
