BACKGROUND AND OBJECTIVES The purpose of this study is to investigate characteristics of synchronous and metachronous cancer in gastric cancer and to suggest appropriate methods of treatment management. METHODS We reviewed 4,593 patients who underwent operations for gastric cancer at Seoul National University Hospital from 1999 to 2005. We selected those(More)
PURPOSE The poor prognosis of hepatocellular carcinoma (HCC) is, in part, due to the high rate of recurrence even after "curative resection" of tumors. Therefore, it is axiomatic that the development of an effective prognostic prediction model for HCC recurrence after surgery would, at minimum, help to identify in advance those who would most benefit from(More)
Hepatocellular carcinoma (HCC) and cholangiocarcinoma (CC) are the major adult liver cancers. The existence of combined hepatocellular-cholangiocarcinoma (CHC), a histopathologic intermediate form between HCC and CC, suggests phenotypic overlap between these tumors. Here, we applied an integrative oncogenomic approach to address the clinical and functional(More)
BACKGROUND Although the prognosis of early gastric cancer (EGC) is considered to be satisfactory, some patients experience disease recurrence after curative resection. This study was aimed at evaluating the recurrence rate, the recurrence patterns and the prognostic factors for recurrence of EGC as well as treatment results after recurrences. METHODS We(More)
BACKGROUND AND AIM Although more than 80% of undifferentiated early gastric cancers (EGC) are not associated with lymph node metastasis, endoscopic mucosal resection is not generally accepted as a means of curative treatment because of an abundance of conflicting data concerning clinicopathological characteristics and prognoses. The aim of this study was to(More)
BACKGROUND Although the TNM stage is the most important prognostic factor for gastric cancer, there is a need for new prognostic and predictive factors, because the prognosis varies among patients of the same stage. The purpose of this study was to clarify the relationship of p53, nm23, proliferating cell nuclear antigen (PCNA) and c-erbB-2 with the(More)
BACKGROUND The seventh TNM staging system for gastric cancer of the American Joint Committee on Cancer/International Union Against Cancer (AJCC/UICC) had a more detailed classification than the sixth TNM staging system for both the tumor (T) and lymph nodes (N). The authors compared survival rates assessed by the seventh staging system with those by the(More)
BACKGROUND Preoperative accurate diagnosis of the T and N stages in early gastric cancer (EGC) is important in determining the application of various limited treatments. The aim of this study is to analyze the accuracy of T and N staging of EGC with esophagogastroduodenoscopy (EGD), Stomach protocol CT (S-CT), and endoscopic ultrasonography (EUS), and the(More)
The role of hepatic resection for metastatic gastric cancer is less well defined due to the tendency of gastric cancer to widely metastasize. The purpose of this study is to examine the beneficial effect of hepatic resection in patients with metastatic gastric cancer. The clinicopathologic features and long-term results of 11 patients who underwent hepatic(More)
OBJECTIVES The purpose of this study was to determine the outcome of surgical resection for pancreatic cancer and to characterize the clinicopathologic features of actual long-term survivors. METHODS Of the 789 pancreatic cancer patients, we retrospectively analyzed 242 patients who underwent an operation between 1985 and 1999. Surgical resection with(More)
