목적: TNM 분류법의 임상적 분류법과 병리학적 분류법은 항상 일치하지는 않는다. 진행성 위암의 육안적 침윤정도 특히 육안적 장막침윤의 의의를 파악하고, 육안적 침윤정도와 병리학적 침윤정도의 일치율을 높일 수 있는 방안을 모색하고자 하였다. 대상 및 방법: 1995년부터 1999년까지 경북대학교병원 외과에서 진행성 위암으로 수술 받은 789명의 환자를 대상으로 하였다. 육안적 및 병리학적 장막침윤 여부에 따른 환자의 예후와 재발양상을 분석하고 육안적 장막침윤과 병리학적 장막침윤이 일치하지 않는 경우는 이에 영향을 주는 인자를 찾았다. 결과: 병리학적 장막침윤에 따른 예후뿐 아니라 육안적 장막침윤에 따른 예후도 유의한 차이를 나타내었다. 육안적 장막침윤이 있는 경우의 42.2%와 병리학적 장막침윤이 있는 경우의 41.4%에서 재발하였으며, 복막재발의 빈도는 19.8% 및 21.9%로 비슷하였다. 육안적 장막침윤 판정의 민감도는 70.3%, 특이도는 77.0%, 양성예측도는 56,4%, 음성 예측도는 86.5%이었다 cT3/ss cancer와 cT3/se cancer와의 비교에서 원격전이 유무 및 육안적 형태에 따라서 유의한 차이를 나타내었고, 다변량 분석에서 두 변수 모두 cT3 cancer가 병리학적으로 ss cancer로 판정될 위험 인자이었다. 결론: 종양이 Borrmann I형이나 II형인 경우와 원격 전이가 없는 경우에는 육안적으로 장막침윤이 있더라도 병리학적으로는 장막침윤이 없을 가능성이 있기 때문에 주의를 요하지만, 위암의 육안적 장막침윤 여부는 환자의 생존율과 근치적 수술 후의 재발양상을 잘 반영하기 때문에 종양학적 가치가 충분하다.

Purpose: The macroscopic diagnosis of tumor invasion through the serosa during surgery is not always distinct in patients with gastric cancer. The prognostic impact of the difference between macroscopic findings and pathological diagnosis of serosal invasion is not fully elucidated and needs to be re-evaluated. Materials and Methods: A total of 370 patients with locally advanced pT2 to pT4a gastric cancer who underwent curative surgery were enrolled in this study. Among them, 155 patients with pT3 were divided into three groups according to the intraoperative macroscopic diagnosis of serosal invasion, as follows: serosa exposure (SE)(-) (no invasion, 72 patients), SE(${\pm}$) (ambiguous, 47 patients), and SE(+) (definite invasion, 36 patients), and the clinicopathological features, surgical outcomes, and disease-free survival (DFS) were analyzed. Results: A comparison of the 5-year DFS between pT3_SE(-) and pT2 groups and between pT3_SE(+) and pT4a groups revealed that the differences were not statistically significant. In addition, in a subgroup analysis of pT3 patients, the 5-year DFS was 75.1% in SE(-), 68.5% in SE(${\pm}$), and 39.4% in SE(+) patients (P<0.05). In a multivariate analysis to evaluate risk factors for tumor recurrence, macroscopic diagnosis (hazard ratio [HR], SE(-) : SE(${\pm}$) : SE(+)=1 : 1.01 : 2.45, P=0.019) and lymph node metastasis (HR, N0 : N1 : N2 : N3=1 : 1.45 : 2.20 : 9.82, P<0.001) were independent risk factors for recurrence. Conclusions: Gross inspection of serosal invasion by the surgeon had a strong impact on tumor recurrence in gastric cancer patients. Consequently, the gross appearance of serosal invasion should be considered as a factor for predicting patients' prognosis.

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.
