Home-based exercise during preoperative therapy for pancreatic cancer.

PURPOSE: Exercise concurrent with neoadjuvant chemotherapy and/or chemoradiation for pancreatic adenocarcinoma (PDAC) may mitigate the decline in function that may occur as a result of the disease or its treatment in the preoperative period. The primary objective of this single-arm prospective trial was to determine adherence to a home-based exercise program administered during preoperative therapy.

METHODS: Twenty patients from a quaternary cancer center with potentially resectable PDAC were enrolled. Patients were prescribed a minimum of 120 min of moderate-intensity exercise weekly: at least 60 min of aerobic exercise and 60 min of resistance exercise. Self-reported exercise was recorded in daily logs. Functional and survey measures were collected upon enrollment, following preoperative therapy, and 1 month after surgery.

RESULTS: Fifteen out of 20 patients participated in the program. They reported a mean (standard deviation (SD)) of 98.6 (69.8) min of aerobic exercise weekly and 57.4 (36.0) min of strengthening exercise weekly over a median of 17 weeks (range, 5-35 weeks) of preoperative therapy, for a mean (SD) of 156.0 (64.5) min of total exercise weekly. Eighty percent reported a mean of least 120 min of total exercise weekly during preoperative therapy. Patients with low baseline physical activity based on the International Physical Activity Questionnaire significantly increased their preoperative physical activity (p = .01). There were no adverse events associated with the exercise program.

CONCLUSIONS: Patients with PDAC will participate in a home-based exercise program of aerobic and strengthening exercise and will increase physical activity, concurrent with preoperative chemotherapy and/or chemoradiation.
