Total or subtotal gastrectomy for gastric carcinoma? A study of quality of life

Abstract

The aim of this study was to compare quality of life after total gastrectomy (TG) with that after subtotal gastrectomy (STG) for gastric carcinoma. The value of the routine use of TG de principe in the treatment of gastric carcinoma, wherever the tumor may be sited in the stomach, remains controversial. The advocates of TG contend that when it can be performed safely, with relatively low operative mortality and morbidity, it yields better long-term survival than STG. Most surgeons, however, believe that the routine use of TG increases both operative mortality and morbidity and the risk of nutritional deficiency in the long term, without improving survival. TG may also be associated with poorer outcome in terms of quality of life (QOL), but the evidence for this is tenuous. Forty-seven consecutive patients who had undergone potentially curative (R0) gastric resection for carcinoma were studied: 26 had undergone TG and 21 STG. A radical D2 lymph node dissection had been performed in each, and all patients were free from recurrence at the time of the study. QOL was measured before operation and 1, 3, 6, and 12 months after operation by means of five questionnaires to measure functional outcome: the Rotterdam symptom checklist (RSCL), the Troidl index, the hospital anxiety and depression (HAD) scale, activities of daily living score, and Visick grades. Before operation there was no significant difference in QOL between the two groups of patients. At 1 year after operation, however, patients who had undergone STG had a significantly better QOL than patients who had undergone TG: Their median RSCL score was lower (10 versus 19 respectively, p < 0.05), and their Troidl index was higher (11 versus 9 respectively, p < 0.05). The QOL of patients who underwent STG was also significantly better after operation than it had been before operation, whereas the QOL of the TG group was not significantly better after operation than before operation. The QOL of patients was found to be significantly better after STG than after TG for gastric carcinoma. Because operative mortality is greater and long-term survival is no better after TG than after STG, the latter is recommended as the treatment of choice for tumors of the distal stomach.
