Vitamin D deficiency in patients operated on for gastric lymphoma

Abstract

Objective. To determine the nutritional status in patients treated for gastric non-Hodgkin's lymphoma (NHL).Material and methods. Patients treated during the period 1990–99 according to a protocol including primary gastric surgery for eligible patients were registered prospectively in successive patients. Those with aggressive lymphomas in stage IE–IIE underwent gastric surgery followed by CHOP-like chemotherapy. Patients with indolent lymphomas and localized disease did not receive any further treatment if the operation was considered radical; otherwise, they received local radiotherapy after surgery. Patients with advanced disease underwent gastric surgery only if there was a considerable risk of bleeding or perforation. Patients below the age of 80 years and in complete remission were offered a cross-sectional examination a median of 102 months later, including clinical examination with estimation of body mass index, upper endoscopy and blood tests (haemoglobin, ferritin, serum-Fe, total iron-binding capacity (TIBC), vitamin B12, homocysteine, vitamin D status, parathyroid hormone (PTH), albumin and electrolytes).Results. Forty patients were identified, of whom 33 met for follow-up examination. Seventeen patients had a partial gastrectomy (PG), 9 a total gastrectomy (TG) and 7 patients were not operated on. The patients in the TG group had significant weight loss. Furthermore, the patients in the TG group had a lower storage iron content (s-ferritin and s-iron saturation), lower s-vitamin D, higher s-PTH and homocysteine than the other groups.Conclusions. If surgery is necessary for gastric lymphomas, a PG should be performed when possible. The patients should receive dietary advice and be followed-up at least yearly for nutritional deficiencies. Regular intake of vitamin D and -B12, calcium, folate and iron should be considered.
