Patient reported distress is predictive of survival in patients with gastrointestinal tumors.

Abstract

764 Background: Psychosocial distress screening and assessment in patients with gastrointestinal (GI) cancers has an established importance due to the distress experienced during and post treatment. GI cancer patients receiving radiotherapy (RT) for curative or palliative measures were reviewed in order to determine if there was a relationship between patient reported distress (PRD) and survival. Methods: Patients at our institution who receive external beam RT for GI cancers completed a 30 question PRD survey that also included a linear analog measure of overall distress, the National Comprehensive Cancer Network (NCCN) Distress Thermometer, which ranged from 1 (low overall distress) to 10 (high overall stress) at the start of and/or during treatment. Each question on the PRD questionnaire concentrated on a possible cause of distress. It allowed patients to rate distress levels for each question from 1 to 5 (1 being the least distressed and 5 being the most distressed), and also overall distress according. The reported clinical results of the PRD questionnaire were retrospectively reviewed in patients receiving RT for GI cancers from Jan 2012 to Aug 2015. Patients were considered distressed if their overall PRD score was 5 or greater (PRD+) or not distressed (PRD-) if their score was 4 or under. Overall survival between PRD+ and PRD- was compared using the Kaplan-Meier method. Results: PRD surveys were completed by 134 consecutive patients, 67 (50%) male and 67 (50%) female within 30 days of starting RT. The median age was 65 years (range 28 to 93). The top histological finding was adenocarcinoma, 90 patients (60%). 113 (84%) received chemotherapy and 64 (48%) underwent surgery. 102 (75%) treatments were curative and 32 (25%) were palliative. Overall NCCN distress thermometer results ranged from 0 to 10, with a median of 4. Median follow-up was 2.7 years. Distressed patients (PRD+) had inferior survival to those not distressed (PRD-) at 2 years, 52% vs. 72%, p<0.02. Conclusions: Patient reported distress is associated with an inferior survival in patients receiving radiotherapy for gastrointestinal tumors.
