Influence of gastrectomy on medical chronic illness in patients with early gastric cancer latent tuberculosis, tuberculosis, early gastric cancer, gastrectomy, interferon gamma assay, pharmacokinetic, HEE SEOK LEE I. Development of active tuberculosis from latent tuberculosis in patients with early gastric cancer who underwent gastrectomy The study compared patients with early gastric cancer (EGC) who underwent gastrectomy(gastrectomy group) with those with EGC who underwent endoscopic submucosal dissection (control group). After being diagnosed with latent tuberculosis in each group via commercial interferon-γ assay (IGRA) the patients in each group were followed to identify whether they had active tuberculosis. From February 2012 to October 16 2014, 584 patients with EGC in total were enrolled in the study. Among them, 339 of gastrectomy group and 188 of control group underwent IGRA. The test results said that the diagnosis rate of latent tuberculosis in each group turned out 47.8% and 46.3%, respectively, which refers to no significant difference between the two groups regarding the rate (P=0.568). It is assumed that low number of patients enrolled to the study and short follow-up period contributed to no active tuberculosis. Thus, the study needs to be continued. II. Pharmacokinetic characteristics of anti-tuberculous drugs in gastrectomized patients As active tuberculosis was found at our hospital, pharmacokinetic testing was implemented to 15 of gastrectomy group and 10 of control group, to whom the first-line TB drugs (HREZ) had been administered. As for Rifampin, Tmax was significantly extended in gastrectomy group(p=0.005), that also showed lower value in Cmax (P=0.055). In pyrazinamide, the gastrectomy group had significantly low value in AUC last (P=0.021). The study found for the first time that the treatment group had difficulties in absorbing anti-tuberculous drugs. III. Delayed response to anti-tuberculous treatment in gastrectomized patients The patients with pulmonary TB which was drug susceptible at our hospital, were divided into gastrectomy and control groups. Each group was set to receive treatment for a certain period of time (6mo vs 9 mo), respectively. Before the end of the period, lesions would be evaluated through LDCT. In case that more than 50% of the lesions disappear, treatment would stop. If more than 50% lesions remain, the treatment period would be extended to more than three months, depending on the patient s condition. Among 35 pulmonary TB patients, 16 and 19 were categorized into gastrectomy and control groups. Eight(50%) out of 16 in treatment group showed delayed response to the treatment during the designated period so their treatment was extended. In control group, 4(21.1%) out of 19 had extended period of the treatment(p=0.072). The results illustrated for the first time that the treatment group had delayed response to the treatment. Statistically significant outcome is expected as more patients will be registered to the study by next year.
IV. Influence of gastrectomy on chronic metabolic diseases Gastric cancer is the one of the leading cause of cancer death in the world including Korea. The survival of gastric cancer patients is improved as the increase of early gastric cancer (EGC) patients proportion by screening program in Korea. As the long term survivors increased, the improved quality of life (QOL) is essential problem in these patients. One of the factor impairing the QOL in these patients is the chronic metabolic disease like diabetes mellitus (DM) and hypertension which are the also a health problem in the world. However, studies about the effect of gastrectomy on the DM and hypertension are few and most of them are retrospective fashion with small number of patients. In this study, the EGC patients with gastrectomy was compared patients with endoscopic submucosal dissection (ESD) patients as for the control group. The gastrectomy was divied as total, subtotal with gastroduodenostomy, subtotal with loop gastrojejunostomy and subtotal with Roux-en Y gastrojejunostomy group. Each group is planned for 30 patients and the DM and hypertension data was collected at preoperately, 3 month and 1 year later after surgery. The enrolled patients was 142 but 65 patients were dropped out due to the reason of preference to local hospital and long distance from national cancer center. However, the analysis was done in avalable patients even in small number of patients in each subgroup. In DM patients the blood sugar was decreased in ESD and gastrectomy patients in 3 months but the ESD patient showed impaired as time goes on. The body weight was significantly decreased in gastrectomy group and the gastrointestinal hormonal change was not observed. In hypertension patients, body weight and blood pressure were significantly improved in gastrectomy patients in 3 months. The oral intake measured by diet diary showed no difference between ESD and gastrectomy patients even the body weight was significantly decreased in gastrectomy group. The the more data of completely enrolled patients are needed for analysis. In conclution, the DM and hypertension are impred in short term period after the gastrecomy in EGC patients.
