Survival and daily physical activity in patients treated for advanced midgut carcinoid tumors☆☆☆

Abstract 

Background. Prospects for survival and quality of life ought to influence treatment strategies in patients with midgut carcinoids.

Methods. A total of 121 patients with midgut carcinoid received a combined medical and surgical treatment from 1980 to 1993. In all, 158 operations were undertaken for removal of mesentericointestinal lesions and occasional liver metastases or as repeat intervention for abdominal complications. Survival was analyzed together with estimates of daily physical activity during follow-up.

Results. Cause of death (63 patients) included carcinoid heart disease (41%) and cachexia (mesentericointestinal entrapment, 35%). Median survival was 11 years in patients with irresectable mesenteric metastases, 7 years with liver metastases, and 1 year with extraabdominal spread. Extensive liver metastases or substantial weight loss (9 kg or greater) reduced survival to a median of 4 to 5.5 years, and surgically treated intestinal ischemia reduced survival to a median of 8 years. Patients with carcinoid syndrome survived a median 7 years, those with 5-hydroxyindoleacetic acid values greater than 500 μmol/24 hr or a valvular heart disease survived a median of 5 years, those with heart failure a median of 2.5 years. Most patients retained an acceptable daily physical activity; impairment occurred in cases of malnutrition, high 5-hydroxyindoleacetic acid values, or heart valve fibrosis, and activity was markedly reduced in the presence of extraabdominal metastases or overt heart disease.

Conclusions. Favorable survival statistics and the maintenance of daily physical activity support active medical and surgical management in patients with advanced midgut carcinoids.
