Gastric cancer remains the second most common cancer in Korea; however, its mortality has decreased due to earlier diagnosis. In Korea, screening endoscopy has been performed nationwide since 1999. The aim of this study was to elucidate the benefit of screening endoscopy on actual survival in gastric cancer patients and to determine the optimal interval of screening endoscopy.We analyzed 1651 p...

Gastric cancer currently ranks fourth in cancer-related mortality worldwide. In the western world, it is most often diagnosed at an advanced stage, after becoming metastatic at distant sites. Patients with advanced disease (locally advanced or metastatic) have a somber prognosis, with a median overall survival of 10-12 mo, and palliative chemotherapy is the mainstay of treatment. In recent year...

We have investigated the expression of osteopontin (OPN) and CDX2 in advanced gastric cancers, and analyzed correlations with clinicopathological features to assess their prognostic potential. One-hundred and nine patients suffering from gastric cancer were recruited. Expression of OPN and CDX2 and other molecular markers was determined by immunohistochemistry. The total positive rate for OPN e...

With advances of combined modality therapy, prognoses in esophageal cancer have been improving. After resection of esophageal cancer, the development of gastric tube cancer is a risk. While such cancer in an early stage can be cured endoscopically, total gastric tube resection is indicated in advanced stages. A 68-year-old man underwent subtotal esophagectomy reconstructed with a gastric tube t...

BACKGROUND: Although many treatments for advanced gastric cancer have been developed, systemic therapy remains elusive. METHODS: The author reviewed data on recent phase II and III trials of the main new agents and combinations. RESULTS: Chemotherapy appears to improve survival of patients with advanced disease, albeit slightly. New drugs that might improve response rates and survival include t...

Gastric cancer remains a significant problem in terms of global health, and is the most common cancer in Korea. Surgery is the only potentially curative treatment for localized gastric cancer, but most cases present at an advanced stage. Randomized trials have demonstrated that chemotherapy for advanced gastric cancer improves the quality of life and extends survival, by 4 approximately 6 month...

24 GASTRIC CANCER Despite its decline in incidence over the past few decades, gastric cancer is still the second most common cancer worldwide. Approximately one-half of patients with gastric cancer are not surgical resection candidates due to advanced disease at presentation. Those who undergo potentially curative resections have a high rate of both local and distant recurrence. Gastric cancer ...

Background: This study evaluated whether IMRT using fewer beams and segments could reduce delivery time without compromising plan quality in gastric cancer adjuvant radiotherapy. Materials and Methods: Fifteen patients with advanced gastric cancer who underwent D2, R0 surgery were included in this study. IMRT plans for each patient were designed as 7 equal beams with 40 segments, 5 beams with 2...

OBJECTIVE To quantify the cumulative effective dose (cED) of radiation due to repeated CT and PET/CT examinations after curative resection of gastric cancer and to assess the lifetime attributable risk (LAR) estimates based on Biological Effects of Ionizing Radiation VII models. SUBJECTS AND METHODS Patients who underwent a curative resection for gastric cancer between January 2006 and Decemb...

e22031 Background: Recent studies have shown that VEGF expression not in tissues but in serum sample is correlated with tumor vascularity, and high serum VEGF levels could predict poor prognosis in cancer patients. However there are limited data regarding the clinical and prognostic significance of serum VEGF levels per platelet count in advanced gastric cancer. In this study, we conducted a st...
