Surgery for left-sided pancreatic cancer

Abstract

Abstract A total of 590 exocrine pancreatic cancers of the body or tail of the pancreas, operated on between January 1982 and December 1988, were analysed. There were 128 pancreatic resections (group 1), 164 palliative bypasses (group 2) and 293 exploratory laparotomies which included 74 splanchnicectomies (group 3). The mortality rate was lower in group 1 (9 per cent) than in group 2 (19 per cent) (P = 0·012). The mortality rate exceeded 40 per cent in groups 1 and 2 for patients aged more than 70 years with pre-existing organ failure. The morbidity rate was 32 per cent in group 1 and 29 per cent in group 2. Patients with metastases had a median survival of 3·4 months, whatever the operative treatment. In the presence of lymph node involvement there was no significant difference in survival between groups 1 and 2. Patients with no metastases and no lymph node involvement had 1- and 3-year survival rates of 38 and 12 per cent respectively after pancreatic resection. Only patients with a small tumour (⩾ 4 cm), no lymph node involvement and no metastases achieved a significantly better survival after resection (P = 0·049). Curative resection should be reserved for a small tumour confined to the pancreas. Fewer than 10 per cent of patients will be suitable for surgery. For the other cases, resection must be considered as a palliative procedure without a significant improvement in survival. It seems justified to limit palliative surgery to candidates for digestive bypass and to use non-surgical palliation for the remainder.
