  • The role of nodal station No. 14v (along the superior mesenteric vein) in lymphadenectomy for distal gastric cancer remains elusive. A 73-year-old woman underwent endoscopic submucosal dissection for gastric cancer, and was referred to our division for additional surgery because of pathologically non-curative resection. A laparoscopic distal gastrectomy with D1+ dissection was performed, with a final diagnosis of pT1bN1M0, Stage IB (2 nodal metastases to No. 6). Four months post-surgery, abdominal computed tomography revealed a 14-mm solitary nodule along the superior mesenteric vein. The lesion was excised and pathologically identified as a lymph node metastasis. Adjuvant chemotherapy with tegafur-gimeracil-oteracil potassium (S-1) was administered for the metastasis. Presently the patient survives without recurrence, 5.5 years after the second operation. Our findings suggest that there is lymphatic flow from the No. 6 to the No. 14v nodal station. Some patients with a No. 6 metastasis may benefit from a No. 14v lymphadenectomy, even in early-staged disease.

  • 목적: 도파민은 중추신경전달물질이지만 위장관에서 도파민수용체와 결합하여 점막상피세포 증식, 상피세포의 보호, 위암 세포증식과 관련이 있는 것으로 알려져 있다. 본 연구에서는 위암에서 기원한 세포주를 이용하여 도파민과 각각의 도파민 수용체가 위암 세포 증식과 억제에 작용하는 역할에 대해 알아보았다. 대상 및 방법: 위암세포기원에서 각각 유래한 세포주인 SNU601과 KCU-C2를 이용하여 RNA 추출 후 RT-PCR 시행 후 도파민수용체 D1, D2L과 D2S 각각에 대한 primer로 PCR을 시행하여 수용체 유전자의 상대적인 발현정도를 측정하였다. 도파민과 Dl 수용체의 대항제인 SCH 23390과 D2 수용체 대항제인 raclopride를 사용하여 약물처리에 따른 위암세포주에서 세포 증식에 대한 분석을 하였다. 결과: KCU-C2 세포주에서 D1과 D2L과 D2S 유전자 mRNA의 상대적인 발현정도는 모두 높은 발현을 보였지만, SNU 601 세포주에는 mRNA의 발현이 모두 낮은 수준이었으며, 특히 D2L mRNA는 발현되고 있지 않았다. 약물처리에 따른 위암세포주에서 세포증식에 대한 분석에서는 D1과 D2S 수용체를 통한 도파민의 신호는 세포의 증식을 억제하였고 D2L 수용체를 통한 도파민의 신호는 세포의 증식을 유도하였다. 결론: 본 연구를 통해 도파민이 위암의 세포증식과 억제에 관여하며, 도파민의 이러한 효과는 도파민의 신호가 어느 수용체를 통해 전달되었느냐에 따라 위암세포의 증식과 억제가 이루어짐을 알 수 있었다.

  • Endoscopic submucosal dissection (ESD) is a minimally invasive and effective treatment for early gastric cancer. The criteria for determining the suitability and success of ESD have expanded, with changes in the histopathological classification of gastric carcinoma, including results from molecular research. Treatment methods have also diversified to include targeted therapies and immuno-oncology agents. To improve communication between clinicians and pathologists, it is crucial to understand the standardized diagnostic forms of gastric cancer. This study aims to examine the handling method of ESD specimens and describe the pathological findings of gastric tumors.

  • 국내에서 조기위암에 대한 내시경절제술은 잘 선택된 환자에서 적용시 매우 좋은 성적을 보이는 치료법으로 중요한 치료로 자리를 잡았다. 그러나 내시경절제술의 적응증, 최선의 치료 술기, 합병증의 예방과 치료 및 추적관찰 등의 분야에서 아직 명확히 확립되지 못한 부분이 있다. 최근 국내에서 조기위암 내시경절제술에 대한 대규모의 다기관 연구의 성적들이 보고되지 시작하였다. 내시경 점막 절제술이 최소 침습 시술이고 수술과 달리 시술 후 장기 보존이 가능해 환자의 삶의 질이 우수하다는 점, 최근 내시경 시술과 기기의 발전으로 인해 절제 가능한 병변의 크기에 제한이 없어지고 있다는 점 등을 고려할 때 내시경 점막 절제술은 국내에서 조기 위암 치료의 중요한 치료 수단으로서 그 역할이 점차 확대될 것으로 기대된다. 본고에서는 조기위암 내시경 절제술에 대한 최근 국내 결과를 요약하고 향후 발전방향에 대하여 살펴보고자 한다.

  • Background: This study was designed to examine changing trends in localization of gastric cancer in Turkey in recent years. Materials and Methods: A total of 796 adult patients with newly diagnosed, histologically proven adenocarcinomas, treated and followed up at our oncology center between 2000-2011, were examined retrospectively. In all cases tumor localization were identified and recorded with clinicopathological features. Results: The median age was 58 with a range between 22-90 for the 552 men and 244 women. Median follow up was 12 months (1-276) and median overall survival was also 12 months (11.5-12.4). There was a trend for a change in tumor localization from distal to proximal. Survival of patients was low with advanced T and N stage tumours. Positive surgical margins, lymphovascular invasion, perineural invasion, cardioesophageal localization were predisposition factors for metastatic disease in gastric cancer. There was no relation between age or sex and histopathological type of gastric cancer. Conclusions: There is a trend in our country for a change in gastric tumour localization from distal to proximal, with clear significance for treatment choices.

  • PET detects only less than 50% of early gastric cancer and 62-98% of advanced gastric cancer. Therefore, mass screening programs are recommended for all adults over the age of 40 for early detection and early treatment of gastric cancer through endoscopy or various radiological tests. The most important step after being diagnosed with gastric cancer is accurate staging, which mainly evaluates tumor resectability to avoid unnecessary surgery. Important factors that affect tumor resectability are whether the tumor can be separated from adjacent organs or important blood vessels, the extent of lymph node metastasis, presence of peritoneal metastasis, or distant organ metastasis. To evaluate the extent of local tumor invasion, anatomical imaging that has superior spatial resolution is essential. There are a few studies on prognostic significance of FDG uptake with inconsistent results between them. In spite of lower sensitivities for lymph node staging, the specificities of CT and PET are very high, and the specificity for PET tends to be higher than that for CT. Limited data published so far show that PET seems less useful in the detection of lung and bone metastasis. In the evaluation of pleural or peritoneal metastasis, PET seems very specific but insensitive as well. When FDG uptake of the primary tumor is low, the distant metastasis is also known to show low FDG uptake reducing its detection. There are only a few data available in the evaluation of recurrence detection and treatment response using FDG PET.
