Postoperative complications deteriorate long-term outcome in pancreatic cancer patients.

BACKGROUND: Different tumor-specific prognostic factors have been identified in recent years for patients who undergo surgery due to pancreatic head cancer, but the results often were inconsistent. Furthermore, the impact of postoperative complications on patient long-term survival has not been described. METHODS: The long-term outcome of 428 patients who underwent resection of pancreatic head cancer at our center during a 17-year period was evaluated. Perioperative details, including postoperative complications, as well as the follow-up of all patients who left the hospital postoperatively were collected in a prospective database. Univariate and multivariate models were used to identify potential prognostic factors and to evaluate the impact of postoperative complications on long-term survival. RESULTS: The median survival was 15.5 months with a postoperative complication rate (grade I-IV) of 32.7%. Independent prognostic significance was detected for grading (P < 0.001), R status (P = 0.001), and lymph node status (P = 0.003). The occurrence of severe postoperative complications (grade III-IV) was associated with a significantly shortened survival (16.5 vs. 12.4 months; P = 0.002) and was identified as an independent prognostic factor (P = 0.002). CONCLUSIONS: This large study demonstrates that severe postoperative complications have a strong impact on the long-term survival of patients with pancreatic head cancer comparable to tumor characteristics, such as lymph node status, grading, or R status. As a result, the improvement of surgical procedures in specialized centers might lead to a survival benefit in these patients.

Safety of liver resection and effect on quality of life in patients with benign hepatic disease: single center experience.

BACKGROUND: Although liver resection has long been established for selected patients with benign hepatic disease, the success of surgical treatment of these patients cannot be evaluated exclusively through postoperative morbidity and mortality. Therefore, the aim of the study was to prove the safety of liver resection in the treatment of benign liver tumors and to evaluate the effect of surgical treatment on the patients' quality of life. METHODS: A total of 146 patients who underwent liver resection because of benign liver tumors were included in this study. Postoperative outcome was assessed and patients evaluated their quality of life before surgery and at the present time using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core-30 (QLQ C-30). RESULTS: The rate of serious (> grade 2) complications was 4.1% with no postoperative death. The quality of life assessment revealed an overall improvement of general health status after resection (0.7 vs. 0.56, p < 0.001) and additionally a significant reduction of 6 out of 9 symptoms. Furthermore, compelling benefits in the patients' social and emotional coping could be detected after surgery. CONCLUSIONS: Liver resection for benign liver disease is a safe procedure and leads to a significant improvement of quality of life in selected patients.

Long-term results after liver transplantation.

Liver transplantation (OLT) has become a successful surgical therapy for terminal liver failure. We here report about long-term results of OLT in a single center over a period of 15 years. Between 1988 and 2002, 1365 adult OLTs were performed. Mean follow-up was 103 +/- 56 months. Main indications for OLT were viral-induced cirrhosis (27.1%), alcoholic liver disease (21%), tumors (15.7%) and cholestatic liver disease (14.6%). Retransplantation was necessary in 120 (9.6%) patients because of initial nonfunction (26.9%), recurrence of underlying disease (20.2%), acute and chronic rejection (16.8%) or thrombosis of the hepatic artery (16.8%). 275 patients (22.1%) died. Causes of death included recurrence of disease (32.1%), infections (21.8%), de novo malignancies (13.5%) and cardiovascular disease (11.6%). Patient survival after OLT was 91.4%, 82.5%, 74.7% and 68.2% after 1, 5, 10 and 15 years, and graft survival was 85.8%, 75.3%, 67.3% and 61.7% after 1, 5, 10 and 15 years, respectively. Patient survival after retransplantation was 81.6%, 68.8% and 57.1% and 48.0% after 1, 5, 10 and 15 years. This analysis reveals excellent long-term results after OLT achieved in a single center.
