Abstract

Purpose: There have been reported that preoperative chemotherapy for treating noncurative gastric cancer could increase the R0 resection rate by downstaging the gastric cancer. Yet there have been only rare reports about the effect of preoperative chemotherapy on performing surgery for noncurative gastric cancer. Our study was designed to analyze our experiences with these effects. Materials and Methods: We retrospectively analyzed 46 patients who had undergone gastrectomy after chemotherapy between December 2001 and January 2009. The patients' preoperative condition, the operative findings and the postoperative clinical coursed were analyzed. Results: Preoperative chemotherapy was performed for a mean of 4.4 cycles. Four patients showed a level of ANC below 1,500 (${\mu}/L$) and above a 10 percentile weight loss, respectively. For an operation, we found fibrosis or fixation between the tumor and the adjacent organs in 29 patients, and 4 of the 13 patients who underwent resection with another organ were documented to have invasion by tumor. Forty one patients underwent curative resection. Ten patients developed postoperative complications. There was no mortality at postoperative 60 days. Conclusion: We assumed that preoperative chemotherapy had little effect on the patient preoperatively, and it had some effect on down-staging pathologically. Preoperative chemotherapy didn't increase the postoperative complication rate.

목적: 최근들어 근치적 절제가 어려운 위암을 대상으로 수술 전 항암요법(preoperative chemotherapy)이 병기를 낮추어 완전 절제율을 높일 수 있다는 연구가 보고되고 있으나, 항암요법이 수술에 미치는 영향에 대한 연구가 부족하여 본원의 경험을 조사하고자 하였다. 대상 및 방법: 2001년 12월부터 2009년 1월까지 동일한 항암요법을 시행 받은 후 위 절제술을 시행한 46명을 대상으로 수술 전 전신 상태, 수술 소견 및 수술 후 임상 경과등을 분석하였다. 결과: 항암요법은 평균 4.4회가 시행되었고, 각각 4명의 환자들에서 절대 호중구 수치(absolute neutrophil count)가 1,500(${\mu}/L$) 이하로 떨어지거나 10% 이상의 체중 감소를 보였다. 29명은 수술 중 종양과 주위 장기와의 유착 또는 단단하게 고정된 소견을 보였으며, 근치적 목적의 병할 절제를 시행한 13명의 환자 중 4명만이 병리학적으로 타 장기 침범이 관찰 되었다. 근치적 위 절제술은 41명, 수술 후 합병증은 10명에서 발생하였으며, 수술 후 60일 내 사망은 없었다. 결론: 항암요법이 수술 전 환자에 미치는 영향은 적을 것으로 생각되며, 타 장기 침범 소견으로 병합절제를 시행한 상당수에서 종양이 없었던 것은 일부 항암 효과가 작용한 것으로 생각한다. 더불어 항암 요법 자체가 수술 후 합병증 발생률을 높이는 것으로 생각되지 않는다.
