To determine the current status in various aspects of gastric cancer in Thai patients, we retrospectively reviewed the records of 119 patients with histologically proven gastric cancer in King Chulalongkorn Memorial Hospital during the five-year period from 1994 to 1998. There were 72 males (60.5%) and 47 females (39.5%) with ages ranging from 22 to 91 years (mean age 60.2+/-15.1 years). Among these, 20 patients (16.8%) were younger than 40 years. The duration of symptoms prior to first presentation averaged 20 weeks and dyspepsia and weight loss were the most common complaints. Lesion location was lower third in 40.3 per cent, middle third in 31.9 per cent, upper third in 15.1 per cent and entire stomach in 3.4 per cent of patients. Adenocarcinoma was the most common histological finding (91.6%), followed by lymphoma and leiomyosarcoma (3.4% each). Helicobacter pylori infection was detected in 17 of 25 (68%). The TMN staging was as follows: stage II, 5.9 per cent; stage III, 9.2 per cent; and stage IV, 68.9 per cent. (the stage was unknown in 16%). The overall 1-year, 2-year and 5-year survival rates were 51.6 per cent, 17.5 per cent and 4.4 per cent, respectively. Management was surgical treatment in 58.9 per cent (total gastrectomy 14.5%, subtotal gastrectomy 33.3% and palliative bypass surgery in 11.1%). Systemic chemotherapy was the primary modality of therapy in 16.8 per cent and was adjuvant therapy in 18.5 per cent. The median survival time of resectable cases was 1.00+/-0.53 years, significantly longer than that of unresectable cases (0.11+/-0.03 years) (p=0.0025). However, the administration of chemotherapy did not improve the survival rate. It is concluded that, in Thailand, gastric cancer continues to be an important health problem and is generally associated with a poor prognosis.
