위암 환자의 수술후 5년 생존율은 조기암의 경우 90%이상으로 매우 좋으나 진행암의 경우 20~30%를 넘지 못한다. 위암의 예후에 영향을 주는 요인 중 조기 발견보다 더 중요한 것은 없으며, 조기암의 진단율에 노력을 기울이는 것이 현실적 타개책이라 하겠다. 현재 우리나라의 조기암 진단율은 16~22%로 일본의 40~45%보다 극히 저조하므로 소화기계 증상이 있는 경우 위내시경 검사를 적극 권고함이 바람직하다. 위암은 외과적 절제술이 유일한 근치치료법임은 주지의 사실이며 근래에는 위내시경 및 복강경을 이용하여 위장관 기능을 보존하는 술식도 시도되고 있어 바람직한 발전이라 사료되나, 림프절 곽청의 원칙을 훼손하지 않는 범위내에서 이루어져야할 것이다. 근치적 절제술의 정의에 합당한 외과적 치료법만이 5년 생존율 향상을 기대할 수 있으며, 보조적 항암화학요법과 면역요법은 대상 환자의 엄선으로 부분적 치료효과를 기대할 수 있다. 절제불능 위암이나 국소진행암에서 절제율을 높이기 위한 술전치료방법들의 적극적 도입이 바람직하다. 그러나 대상 환자의 선정에 있어 객관적 타당성이 있는 병기 결정 방법과 치료효과를 판정하는 방법의 혁신이 있어야 할 것으로 사료되며 현재의 부정확한 검사방법들의 대안으로 복강경의 이용이 바람직하리라 사료된다.

Peritoneal carcinomatosis (PC) is defined as the dissemination of cancer cells in the peritoneal cavity resulting in deposition of malignant cells onto parietal or visceral peritoneal surfaces, and is associated with malignant ascites. In general, PC has been treated similarly to metastatic cancers of the primary tumor, but associated with unfavorable outcomes as compared to other sites of metastatic disease from the same primary tumor origin. It has been known to have the median survival of only 3-6 months with supportive care alone. PC is an intractable problem to physicians because of its poor prognosis and limited treatment options. Recent studies have reported that a combination of cytoreductive surgery and hyperthermic intraperitoneal chemotherapy improved survival in PC of colorectal cancer. This paper gives overviews of the characteristics, symptoms, prognosis, and diagnosis of PC and current treatment options on PC of stomach, colorectal, and unknown primary origin.

Purpose: There is no established treatment-related prognostic factor for gastric cancer except a curative tumor resection. This study was done to clarify the prognostic value of early postoperative intraperitoneal chemotherapy (EPIC) in patients with serosa-positive gastric cancer. Materials and Methods: We analyzed retrospectively the postoperative survival data of 209 patients with serosapositive gastric cancer treated by surgery and chemotherapy. The survival period for patients was calculated from the date of resection until cancer-related death or the last date of follow-up; Kaplan-Meier survival curves were plotted and compared by using the log-rank test. A multivariate analysis was done by using the Cox proportional hazards model. Results: Statistically significant differences in survival rates were noted based on gender, depth of invasion, lymph node metastasis, distant metastasis, stage, location of tumor, macroscopic type, extent of gastric resection, curability of surgery, and adjuvant chemotherapy. Five-year survival rates of patients who received EPIC and systemic chemotherapy were 49 per cent and 25 per cent, respectively (P=0.009). A multivariate analysis revealed that invasion of an adjacent organ, lymph node metastasis, total gastrectomy, and palliative surgery were poor independent prognostic factors. Also, EPIC had a marginal prognostic value (P=0.056). Conclusion: Perioperative intraperitoneal chemotherapy can possibly be one of the independent prognostic indicators in case of serosa-positive gastric cancer.

Purpose: There are variants of gastric cancer assoclated with predominantly peritoneal spread of with haematogenous metastases. Perioperative intraperitoneal chemotherapy as an adjuvant to surgery is considered as a rational therapeutic modality to prevent peritoneal spread. We evaluated the influence of early postoperative intraperitoneal chemotherapy on the prognosis of resectable advanced gastric cancer. Materials and Methods: From 1990 to 1995, 246 patients with biopsy proven advanced gastric cancer were enrolled in the study. Among them 123 patients received early postoperative intraperitoneal mitomycin C and 5-fluorouracil. The survival rate was calculated using by the Kaplan-Meier method and was compared using the log-rank test according to 13 clinico-pathologic factors. Multivariate analysis was performed with the Coxproportional hazards model. Results: Gastric resection plusearly postoperative intraperitoneal chemotherapy showed an improved survival rate as compared to surgery alone ($54.1\%\;versus\;40.3\%;$ P=0.0325). Depth of tumor invasion, degree of regional lymph vode metastasis, distant metastasis, tumor size, tumor location, extent of gastric resection, and curability of surgery significantly influenced survival. When a multivariate analysis was performed, depth of tumor invasion, lymph node metastasis, early postoperative intraperitoneal chemotherapy, curability of surgery, and extent of gastric resection emerged as the statistically significant and independent prognostic factors. Conlusion: Early postoperative intraperitoneal chemotherapy is one of the independent prognostic indicators of resectable advanced gastric cancer.

Pseudomyxoma peritonei (PMP) is a rare clinical syndrome characterized by profuse jelatinous materials in the abdominal cavity and pelvis with mucinous implants on the peritoneal surface. There are some studies for serum tumor markers, including carcinoembryonic antigen (CEA), carbohydrate antigen 19-9 (CA19-9) and carbohydrate antigen 125 (CA125), to assess the risk of recurrence following cytoreductive surgery and intraperitoneal chemotherapy. However, rare cases were reported about recurrence with increasing serum CEA levels. Herein, we report a case of recurrence of PMP according to serially elevated serum CEA.
