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.

Gastroesophageal reflux disease (GERD) is one of the most prevalent gastrointestinal disorders. The key feature of GERD is reflux of gastric contents into the esophagus. Medical treatment with proton-pump inhibitors (PPIs) is well established and is considered the standard treatment. Given the high prevalence of the condition and the excellent response to medical therapy, antireflux surgery is an option for patients with volume reflux that is not properly controlled by medical therapy. Adenocarcinoma is a rare but life-threatening complication of GERD. The only known precursor lesion for esophageal adenocarcinoma is Barrett's esophagus. In recent years, a clearer understanding of the development of Barrett's and of its progression toward invasive cancer has developed. Genetic factors almost certainly determine the individual risk. The length of the Barrett's esophagus segment and the size of a hiatal hernia are associated with the risk of developing high-grade dysplasia and esophageal adenocarcinoma.With regard to the clinical management of GERD patients with Barrett's, endoscopic surveillance at 3-year intervals is now considered appropriate in the absence of dysplasia. In patients with high-grade dyspepsia, the situation is more difficult. While a considerable proportion of these patients may already have invasive cancers, there is also the possibility that there is only focal dysplasia. For this reason, it is justifiable to carry out curative endoscopic resection. Mucosal ablation procedures may also be appropriate, but these still need to be properly investigated in clinical trials.

We present a case of primary malignant pylorus neoplasia, emphasizing its rarity, the difficulty of diagnosis and the importance of an adequate prepare before the endoscopic procedure. Literature shows that tumors compromising the first, third and fourth segments of duodenum are rare, especially those of the pyloric area, representing only 0.35% of all malignant tumors of the gastrointestinal tract. Adenocarcinoma is the most common histological type, representing 50% of all malignant neoplasias at this site. The most common symptoms are weight loss, nausea, vomiting, abdominal pain, abdominal mass, sudden changes in intestinal habits and iron deficiency anemia secondary to chronic intestinal hemorrhage. Survival after five years is only 18%. We report a case of a seventy-one year-old male referring early satiety, epigastric pain, retrosternal burning and dyspepsia, with unspecific results in complementary exams, since complete gastric emptying was not achieved. As symptoms worsened, the patient was submitted to laparotomy, with identification of gastric dilation and severe pyloric stenosis, macroscopically suggesting malignancy. The chosen procedure was a subtotal gastrectomy. Adjuvant radiotherapy and chemotherapy were not used. The patient is been followed-up without tumor recurrence so far.
