백남선(Nam Sun Paik) 대한종양외과학회 2005 Korean Journal of Clinical Oncology Vol.1 No.2
Since at least the second half of the 19th century, surgeon has played a principal role in the treatment of cancer. At that time radical excision was a core treatment principle for cancer. But according to understanding of much more cancer biology increased, the cancer treatment paradigm-shift occurred. Today, most cancer patients have being treated by multidisciplinary approach. In this situation surgical teams hold the front line in the diagnosis and treatment of cancer. And a surgery, as one part of science has rapidly changed from clinically-oriented science to a technology-oriented profession. Therefore, change of surgeon’s role should be changed for the benefit of our cancer patients, not only to control or cure their disease but also to give more good quality of life. If so, what is a great surgeon in the future? The great surgeon in the next period must have good surgical technique, medical conception, and more morecular biological consensus, comprehension of engineering science, acceptance of continuing professional education and achievement of worldwide mission of cancer treatment. In conclusion, surgeon should be a multi-player and supersurgeon.

Objectives : This study was performed to evaluate the effect of stage shift according to screening of stomach cancer. Methods : Total 840 cases of stomach cancer patients, undergone a surgical operation at Department of Surgery, Kangnam St. Mary's Hospital, The Catholic University of Korea from Jan. 1989 to Dec. 1995, were reviewed by stomach cancer working sheet, and classified as asymptomatic and symptomatic group based on the presence of subjective symptoms on their hospital visit. Their histopathologic stages were analysed. We compared the histopathologic stages of asymptomatic stomach cancer patients with those of symptomatic patients. Results : From the total of 840 patients, asymptomatic patients group comprised 28 cases (3.3%). Proportion of asymptomatic patients tended to increase from 1.9% in 1990, 0.9% in 1991 to 8.6% in 1995. Proportions of asymptomatic patients by stages were 78.6% (stage I), 3.6% (stage III), 17.9% (stage IV) and that of symptomatic patients by stages were 38.2% (stage I), 16.5% (stage II), 24.8% (stage III), 19.1% (stage IV). In less than 40 years old, 50.5% of symptomatic patients were diagnosed as stage I. With increment of ages, proportions of stage I were makedly decreased. It was significantly different between proportion of early gastric cancer in asymptomatic patients (60.1%) and that in symptomatic patients (25.0%). Conclusions : We confirmed stage shift according to screening of stomach cancer. And proportion of early gastric cancer in asymptomatic patients was higher than that in symptomatic patients. This results suggest that screening of gastric cancer be important to reduce mortality and if be indirectly started from 40 years old.

박종익,진성호,방호윤,채기봉,백남선,문난모,이종인,Park, Jong-Ik,Jin, Sung-Ho,Bang, Ho-Yoon,Chae, Gi-Bong,Paik, Nam-Sun,Moon, Nan-Mo,Lee, Jong-Inn 대한위암학회 2008 대한위암학회지 Vol.8 No.1
목적: 유문부보존 위절제술(pylorus-preserving gastrectomy, PPG)은 유문륜을 보존하여 잔위의 배출기능을 보존하고 담즙 역류를 방지할 수 있는 기능 보존 수술법으로 조기위암 치료에 적용되고 있다. 저자들은 복강경 보조 유문부보존 위절제술(laparoscopy-assisted pylorus-preserving gastrectomy, LAPPG)의 초기 경험을 LADG 후 Billroth-I 재건술과 비교 분석하였다. 대상 및 방법: 2006년 11월부터 2007년 9월까지 원자력병원 외과에서 복강경 보조 위절제술을 시행 받은 39명의 조기위암 환자 중 LAPPG (n=9)와 LADG 후 Billroth-I 재건술(n=18)을 시행 받은 27명의 환자를 대상으로 하였고, 양 군간의 임상병리학적 변수를 비교하였다. 저자들은 LAPPG 시행 중 유문하동맥, 우위동맥, 미주신경 간지, 유문지 및 복강지를 보존하였으며, 림프절 절제술은 우위동맥 림프절(No. 5)을 제외한 D1+$\beta$술식을 시행하였고, 유문륜 상방 $3{\sim}4\;cm$에서 원위부 위절제를 시행하였다. 결과: LAPPG을 시행 받은 환자 9명의 평균 연령은 $59.9{\pm}9.4$세였으며 남녀 성비는 1.3 : 1.0 (남자 5명, 여자 4명)이었고, LADG 후 Billroth-I 재건술을 시행 받은 환자 18명의 평균 연령은 $64.1{\pm}10.0$세였으며 남녀 성비는 2.6 : 1.0 (남자 13명, 여자 5명)이었다. LAPPG 군과 LADG 후 Biliroth-I 재건술을 시행받은 군에서 절제된 림프절의 개수는 각각 $28.3{\pm}11.9$개 $28.1{\pm}8.9$개, 수술 시간은 각각 $269.0{\pm}34.4$분, $236.3{\pm}39.6$분, 술 중 출혈량은 각각 $191.1{\pm}85.7\;ml$, $218.3{\pm}156.6\;ml$, 술 후 첫 가스 배출은 각각 $3.6{\pm}0.9$일, $3.5{\pm}0.8$일에 있었고 술 후 첫 유동식은 각각 $5.1{\pm}0.9$일, $5.1{\pm}1.7$일에 섭취하였고 술 후 재원 기간은 각각 $10.1{\pm}4.0$일, $9.2{\pm}3.0$일로 모두 통계학적으로 유의한 차이가 없었다(P>0.05). 술 후 합병증은 LAPPG 군에서 위저류증 1예와 창상 장액종 1예가 발생하였고, LADG 후 Biliroth-I 재건술을 시행 받은 군에서는 좌외측간엽경색 1예가 발생하였다. 결론: 조기위암의 치료에 있어서 LAPPG는 기능 보존 수술 법으로 적용 가능하며, 적절한 적응증을 사용하면 임상종양학적 측면에서도 LADG 후 Billroth-I 재건술과 동등한 결과를 보일 것으로 기대된다. Purpose: Pylorus-preserving gastrectomy (PPG), which retains pyloric ring and gastric function, has been accepted as a function-preserving procedure for early gastric cancer for the prevention of postgastrectomy syndrome. This study was compared laparoscopy-assisted pylorus-preerving gastrectomy (LAPPG) with laparoscopy-assisted distal gastrectomy with Billroth-I reconstruction (LADGB I). Materials and Methods: Between November 2006 and September 2007, 39 patients with early gastric cancer underwent laparoscopy-assisted gastrectomy in the Department of Surgery at Korea Cancer Center Hospital. 9 of these patients underwent LAPPG and 18 underwent LADGBI. When LAPPG was underwent, we preserved the pyloric branch, hepatic branch, and celiac branch of the vagus nerve, the infrapyloric artery, and the right gastric artery and performed D1+$\beta$ lymphadenectomy to the exclusion of suprapyloric lymph node dissection. The distal stomach was resected while retaining a $2.5{\sim}3.0\;cm$ pyloric cuff and maintaining a $3.0{\sim}4.0\;cm$ distal margin for the resection. Results: The mean age for patients who underwent LAPPG and LADGBI were $59.9{\pm}9.4$ year-old and $64.1{\pm}10.0$ year-old, respectively. The sex ratio was 1.3 : 1.0 (male 5, female 4) in the LAPPG group and 2.6 : 1.0 (male 13, female 5) in the LADGBI group. Mean total number of dissected lymph nodes ($28.3{\pm}11.9$ versus $28.1{\pm}8.9$), operation time ($269.0{\pm}34.4$ versus $236.3{\pm}39.6$ minutes), estimated blood loss ($191.1{\pm}85.7$ versus $218.3{\pm}150.6\;ml$), time to first flatus ($3.6{\pm}0.9$ versus $3.5{\pm}0.8$ days), time to start of diet ($5.1{\pm}0.9$ versus $5.1{\pm}1.7$ days), and postoperative hospital stay ($10.1{\pm}4.0$ versus $9.2{\pm}3.0$ days) were not found significant differences (P>0.05). The postoperative complications were 1 patient with gastric stasis and 1 patient with wound seroma in LAPPG group and 1 patient with left lateral segment infarct of liver in the LADGB I group. Conclusion: Patients treated by LAPPG showed a comparable quality of surgical operation compared with those treated by LADGBI. LAPPG has an important role in the surgical management of early gastric cancer in terms of quality of postoperative life. Randomized controlled studies should be undertaken to analyze the optimal survival and long-term outcomes of this operative procedure.

박종익,진성호,방호윤,백남선,문난모,이종인,Park, Jong-Ik,Jin, Sung-Ho,Bang, Ho-Yoon,Paik, Nam-Sun,Moon, Nan-Mo,Lee, Jong-Inn 대한위암학회 2008 대한위암학회지 Vol.8 No.1
목적: 15년 동안 단일 병원에서 위절제술을 시행한 위암 환자를 대상으로 임상병리학적 특성, 생존율과 예후인자를 분석하여 보고하고자 하였다. 대상 및 방법: 1991년 1월부터 2005년 12월까지 15년 동안 원자력병원 외과에서 위암으로 위절제술을 시행받은 6,918명의 환자를 대상으로 의무기록을 후향적으로 조사하였다. 결과: 전체 위암 환자 6,918 예를 대상으로 환자들의 성별, 연령, 종양의 위치, 종양의 육안적 분류, 종양의 병리조직 학적 분류 (WHO 분류), Lauren 분류, 위벽 침윤도, 림프절 전이, 원격 전이, 수술 방법, UICC TNM 병기, 술 후 합병증, 술 후 보조적 항암화학요법, 림프관 침윤, 혈관 침윤, 신경초 침윤 등을 비교하였다. 전체 5년 생존율은 66.8%였다. 단변량 분석 결과 연령, 종양의 위치, 종양의 육안적 분류, WHO 분류에 따른 종양의 병리조직학적 분류, Lauren 분류, 위벽 침윤도, 림프절 전이, 원격 전이, 수술 방법, UICC TNM 병기, 술 후 합병증, 술 후 보조적 항암화학요법, 림프관 침윤, 혈관 침윤 및 신경초 침윤에서 생존율에 유의한 차이가 있었다. 다변량 분석 결과 연령, Borrmann type 4, WHO 분류에 따른 종양의 병리조직학적 분류, 위벽 침윤도, 림프절 전이, 원격 전이, 수술 방법, UlCC TNM 병기, 술 후 합병증, 술 후 보조적 항암화학요법 및 림프관 침윤 이 독립적인 예후인자였다. 결론: 위암 환자의 예후는 수술 당시의 병기에 의해 결정되므로 위암의 조기 진단이 중요하다. 적극적인 수술과 보조적 항암화학요법을 포함한 보다 효과적인 다병합요법이 개발되어야 전체 위암 환자의 생존율을 향상시킬 수 있을 것이다. Purpose: Gastric cancer is the most common malignant tumor in Korea. We reviewed the cases at our institution to identify the survival rates and clarify the prognostic factors of patients with gastric cancer. Materials and Methods: We conducted a retrospective study of 6,918 patients who had received a diagnosis of gastric cancer, and they underwent surgery at Korea Cancer Center Hospital during a 15-year period from 1991 to 2005. Results: The overall 5-year survival rate was 66.8%. The univariate analysis revealed that age, location of tumor, gross type of tumor, the histology according to the WHO classification, the Lauren classification, depth of invasion (T stage), lymph node metastasis (N stage), distant metastasis (M stage), the type of surgery, the UICC TNM stage, postoperative complications, adjuvant chemotherapy, lymphatic invasion, venous invasion and perineural invasion were the significantly different factors of the survival rates. The multivariate analysis revealed that age, Borrmann type 4, the histology according to the WHO classification, depth of invasion (T stage), lymph node metastasis (N stage), distant metastasis (M stage), the type of surgery, UICC TNM stage, postoperative complications, adjuvant chemotherapy and lymphatic invasion were the independent prognostic factors. Conclusion: We have shown a statistically significant association between the survival rates after operation for gastric cancer and the clinicopathologic factors. Early diagnosis of gastric cancer, appropriate surgeryand adjuvant therapy might improve the quality of life and the survival rates of gastric cancer patients.
