Quality of life in a multicenter phase II trial of metastasectomy for intra- and extra-hepatic metastases from colorectal adenocarcinoma.

e14573 Background: The combination of intra- and extra-hepatic metastases (IHM and EHM) from colorectal cancer (CRC) has traditionally been considered a contraindication for surgery. Currently there is a growing interest in resecting IHM and EHM. The purpose of this study was to evaluate the health related quality of life (HRQoL) of patients with IHM and EHM from CRC undergoing complete metastasectomy. Methods: Participants with any number of CRC IHM and up to 3 foci of EHM, resectable with RO intent were eligible for the HRQoL component of a Phase-II multi-institutional trial. The effects of therapy on HRQoL were evaluated using: EORTC-QLQ C30, EORTC-LMC21 and FACT-HEP at baseline, prior to surgery and at 4, 8 and 12 months following complete metastasectomy. Results were compared to baseline. >10% mean score change was considered a minimally important clinical difference (MICD). Results: Twenty-five participants were enrolled with a median age: 57 (range: 32-84) years. Protocol surgery was completed in 18/25 (72%) including 11/25 (44%) staged resections. Perioperative morbidity and mortality was 11/25 (44%) and 1/25 (4%), respectively. Median disease-free survival was 6 (range: 0-17) months. 22/25, 88% participants underwent perioperative chemotherapy. EORTC-QLQ C30 Global-HRQoL remained statistically and clinically unchanged compared to baseline at 4 and 8 months but had a MCID decrease at 12 months (mean score change: 15.3) that was not statistically significant. This was associated with a significant decrease in social and role functioning and an increase in fatigue, pain and dyspnea. FACT-Hep score was statistically lower at 4 months post surgery, without reaching a MICD. There was no difference in any of the subscales analyzed in regards to sex, age or the presence of peri-operative complications. Conclusions: Aggressive metastasectomy of multi-site CRC is feasible and safe. Despite disease recurrence in the majority of patients there was no significant deterioration of Global HRQoL as a result of treatment. There was a transient effect on symptoms including fatigue, pain dyspnea and role functioning, which improved by 12 months. Clinical trial information: NCT00606398.
