Tailored surgery in chronic pancreatitis after implementation of a multidisciplinary team assessment; a prospective observational study.

INTRODUCTION: Optimal management of chronic pancreatitis involves several specialties. Selection of patients for surgery may benefit from evaluation by a multidisciplinary team (MDT), similar to cancer care. The aim of this study was to evaluate outcomes in patients selected for surgery after MDT decision. METHODS: A prospective, observational study of consecutive patients operated for pain due to chronic pancreatitis after implementation of a MDT. The main outcome was Quality of life (QoL) assessed by EORTC-QLQ C30 and pain relief in patients followed >3 months. Complications were registered and predictive factors for pain relief analyzed. RESULTS: Of 269 patients evaluated by the MDT, 60 (22%) underwent surgery. Postoperative surgical complications occurred in five patients (8.3%) and reoperation within 30 days in two. There was no 90-days mortality. Complete or partial pain relief was achieved in 44 of 50 patients followed >3 months (88%). Preoperative duration of pain predicted lower probability of success. Postoperative improvement in QoL was most prominent for pain, appetite and nausea. CONCLUSIONS: After MDT evaluation, one in five patients was selected for surgery. Pain relief was obtained in a majority of patients with improved QoL. A tailored approach through a MDT seems warranted and efficient.

Detection of Circulating Tumor Cells at Surgery and at Follow-Up Assessment to Predict Survival After Two-Stage Liver Resection of Colorectal Liver Metastases.

BACKGROUND: The presence of circulating tumor cells (CTCs) is negatively associated with survival after resection of colorectal liver metastases (CLM). The current study aimed to determine the prognostic value of CTCs and disseminated tumor cells (DTCs) at the time of surgery and the prognostic value of CTCs at follow-up assessment, for patients scheduled to undergo two-stage hepatectomy with portal vein embolization (PVE) for CLM. METHODS: Samples were collected at surgery (blood and bone marrow) and at follow-up assessment (blood) for the period 2008 through 2011. In this study, CTCs were detected with the CellSearch system, and DTCs were detected using standard immunocytochemical analysis. RESULTS: Of 24 patients, 18 completed both stages, and no patients were lost to follow-up. The median overall survival (OS) was 37 months, and the median recurrence-free survival (RFS) was 7 months. At surgery, CTCs were found in nine patients (38 %), and their presence was associated with reduced OS (p < 0.001) and RFS (p = 0.006). Follow-up CTC status was available for 11 patients. All eight patients with positive CTC status experienced recurrence. Two of three patients with negative CTC status remained recurrence free. In seven patients (32 %), DTCs were detected but were not associated with OS or RFS. CONCLUSIONS: The presence of CTCs at surgery is associated with worse OS and RFS for patients undergoing two-stage hepatectomy with PVE for CLM. Analysis of CTCs should be explored further for their potential to assist in treatment decisions and monitoring for CLM patients.
