Purpose: The role of metastasectomy has been debatable and unclear in the treatment for patients with metastatic gastric cancer. Therefore, this study was designed to evaluate the role of metastasectomy on the overall survival of these patients. Materials and Methods: In 2,406 patients who underwent gastrectomy for gastric cancer between 1998 and 2010, 188 (7.8%) patients had their first surgery for metastatic gastric cancer. To minimize the bias of systemic chemotherapy, 99 patients who received postoperative chemotherapy (fewer than 2 cycles) were excluded. The primary gastrectomy or metastasectomy had not been enforced in the following cases. Patients with far advanced peritoneal dissemination, multiple liver and lung metastasis (more than 2), and a poor general condition (Eastern Cooperative Oncology Group>2) were excluded. Based on the metastasectomy, the patients were classified into two groups, gastrectomy with metastasectomy and gastrectomy only group. Results: There was no significant difference between both groups in clinicopathological characteristics except for the mean age (P=0.047). The univariate analysis for overall survival show statistical significances in metastasectomy (P=0.026), distal gastrectomy (P=0.047), and combined resection of another organ (P=0.047) group. With a multivariate analysis, metastasectomy was a significant factor in patient survival after surgery (odds ratio 1.679; P=0.034). Conclusions: Based on our results, we assume that a detailed strategy for surgery is needed to improve the overall survival of patients with metastatic gastric cancer. Therefore, we suggest that a metastasectomy can help prolong overall survival in some patients with metastatic gastric cancer.

Background: This study assessed the efficacy of pulmonary metastasectomy for synovial sarcoma in adult patients. Methods: Fifty patients, diagnosed with pulmonary metastasis from June 1990 to August 2010, were reviewed retrospectively. Twenty-eight patients underwent complete pulmonary metastasectomy, and their survival was evaluated. Age, sex, time to metastatic progression, laterality, number of tumors, size of largest nodule, and number of metastasectomies were analyzed as potential prognostic factors. Results: In all, 29 patients underwent at least one pulmonary metastasectomy, and 51 resections were performed. One intraoperative mortality occurred, and the 5-year survival rate was 58.4%. Bilateral metastases and early metastatic progression were associated with poor survival in multivariate analyses. Conclusion: Surgical resection can be a good option for treating pulmonary metastasis in patients with synovial sarcoma. Repeated resection was feasible with low mortality and morbidity.

Background: Treatment of pulmonary metastasis from urothelial cell carcinoma has been mostly palliative chemotherapy and the role of pulmonary metastasectomy has not been investigated much. Materials and Methods: This study is a retrospective interim review of pulmonary metastasectomy from urothelial carcinoma at single institution between 1998 and 2010. Overall 16 patients underwent pulmonary metastasectomies. Results: There was no postoperative complication or hospital mortality. Mean hospital stay was 6 days. Overall and disease-free 5-year survival were 65.3% and 37.5%, respectively. Conclusion: In selected patients with pulmonary metastasis from urothelial carcinoma, surgical treatment is feasible and could contribute to long-term survival in selected patients.

Gastrointestinal stromal tumors (GISTs) are rare, but are the most common mesenchymal neoplasm of the gastrointestinal tract. The most common sites of metastasis are liver and peritoneum, while bone metastasis is rare. We report on a patient with skull metastasis after seven years of treatment with imatinib for metastatic GIST. She underwent metastasectomy consisting of craniectomy with excision of the mass, and cranioplasty and continued treatment with imatinib and sunitinib, without evidence of cranial recurrence. She died of pneumonia sepsis one year after metastasectomy. Skull metastasis of GIST is a very rare presentation, and an aggressive multidisciplinary approach should be considered whenever possible.

Background: The purpose of this study was to analyze our series of liver resections for metastatic colorectal carcinoma (mCRC) to determine prognostic factors affecting survival and to evaluate the potential roles of neoadjuvant or adjuvant chemotherapy. Materials and Methods: Ninety-nine patients who underwent metastasectomy for liver metastases due to colorectal cancer at the Department of Medical Oncology, 9 Eylul University Hospital between 1996 and 2010 were evaluated in this study. The patients were followed through July 2013. Demographic, perioperative, laboratory, radiological and chemotherapy as well as survival data were obtained by retrospective chart review. Results: In 47 (47.5%) patients, liver metastases were unresectable at initial evaluation; the remaining 52 (52.5%) patients exhibited resectable liver metastases. Simultaneous hepatic resection was applied to 52 (35.4%) patients with synchronous metastasis, whereas 5 (64.5%) patients underwent hepatic resection after neoadjuvant chemotherapy. Forty-two patients with metachronous metastasis underwent hepatic resection following neoadjuvant chemotherapy. R0 resection was obtained in 79 (79.8%) patients. A second hepatectomy was performed in 22 (23.2%) patients. Adjuvant chemotherapy was given to 85 (85.9%) patients after metastasectomy. The median disease-free and overall survivals after initial metastasectomy were 12 and 37 months, respectively, the 1-year, 3-year and 5-year disease-free survival (DFS) and overall survival (OS) rates being 46.5%, 24.3% and 17.9%and 92.3%, 59.0% and 39.0%, respectively. On multivariate analysis, the primary tumor site, tumor differentiation, resection margin and DFS were independent factors predicting better overall survival. Conclusions: In selected cases, hepatic metastasectomy for mCRC to the liver can result in long-term survival. Neoadjuvant chemotherapy did not exert a positive effect on DFS or OS. Adjuvant chemotherapy also did not appear to impact DFS and OS.

배경: 골육종 환자의 폐전이는 외과적 절제술이 표준치료로 인정되고 있으나 반복적인 폐전이에 대한 절제술의 역할은 아직 정립되어 있지 않다. 저자들은 폐전이를 보인 골육종 환자에서 반복적인 폐전이 절제술의 생존율과 예후인자를 알아보고자 하였다. 대상 및 방법: 1990년 1월부터 2005년 7월까지 골육종 폐전이를 진단받은 62명의 환자 중 폐전이 절제술을 시행받은 36명의 환자를 대상으로 후향적 연구를 진행하였다. 결과: 36명의 환자에서 모두 62회의 폐전이 절제술을 시행했으며 18명에서 2차 폐전이 절제술을, 7명에서 3차 폐전이 절제술을, 1명에서 4차 폐전이 절제술을 시행하였다. 1차 폐전이 절제술 후 중앙 생존기간은 20.5개월, 3년 및 5년 생존율은 32.6% 및 29.4%로, 2차 폐전이절제술 후의 중앙생존기간 11.3개월, 3년 및 5년 생존율 34.9% 및 34.9%와 차이를 보이지 않았으나, 3차 폐전이 절제술 후 중앙 생존기간은 7.1개월로 유의하게 짧았다(p=0.01). 장기 생존한 군에서 비-장기 생존자에 비해 여성, 무병생존기간이 12개월 이상, 단일 전이 병소, 구역절제술 이상의 수술이 많았으나 통계학적 차이는 없었다. 결론: 골육종 환자에서 반복적인 폐전이 절제술은 유용한 치료방법이라 생각되며, 일부 환자에서는 장기 생존을 기대할 수 있었다. 예후인자에 대하여는 향후 더 많은 수의 환자를 대상으로 하는 추가적인 연구가 필요하리라 생각한다.

We present an unusual case of bone metastases from renal cell carcinoma around orthopedic implants in a 78-year-old female with osteolytic, expansile, highly vascularized, malignant infiltration around suture anchors in the proximal humerus. The patient had undergone arthroscopic rotator cuff repair using suture anchor implants 6 years previously. After diagnosis of bone metastasis, she was successfully treated with metastasectomy and internal fixation using a plate and screws, with cement augmentation. This report is the first to document metastases around a suture anchor in a bone and suggests the vulnerability of suture anchor implants to tumor metastasis.

배경: 완전절제가 가능한 고형암의 폐전이에 대한 절제술은 이미 표준화된 치료방법이며, 1997년 International Resistry of Lung Metastases (IRLM)에서 대규모의 연구를 통해 전이성 폐암에 대한 병기설정 및 예후인자에 관하여 제시한 바 있다. 국내에서도 전이성 폐암에 대한 수술이 꾸준히 증가하고 있으며, 치료방법의 개선에 따른 생존율 역시 좋아지는 추세이다. 이에 경북대학교병원 흉부외과에서는 지난 10년간 전이성 폐암으로 수술을 받은 환자들의 치료결과에 대해서 조사하였다. 대상 및 방법: 1996년 1월부터 2005년 12월까지 전이성 폐암 환자 89명에 대해서 96예의 폐절제술을 시행하였다. 이들의 의무기록을 토대로 생존율 및 예후에 영향을 미치는 임상적, 병리학적 요인에 대하여 분석하였다. 결과: 환자의 평균나이는 $45.9{\pm}17.4$세($10{\sim}75$세)였으며, 남성이 51명, 여성이 38명이었다. 이 중 암종의 폐전이가 55예, 육종인 경우가 30예, 기타 4예였다. 암종 중에서는 대장암이 35예(64%), 육종 중에서는 골육종이 22예(73%)로 가장 많았다. 원발암 치료 후부터 폐절제술까지의 종양자유기간은 평균 $29.6{\pm}27.9$개월($0{\sim}180$개월)이었으며, 원발암과 동시에 발견된 경우는 3예(3.4%)였다. 전체 환자들의 3, 5, 10년 생존율은 각각 52.5%, 32.1%, 20.7%였고 중앙 생존기간은 38개월이었다. 재수술은 15예(16.8%)에서 시행하였다. IRLM 제시에 따른 병기별 5년 생존율은 1기 63.5%, 2기 33.3%, 3기 22.1%, 4기 0%였다. 36개월 미만의 종양자유기간, 양측 폐전이, 5개 이상의 전이병소를 가진 경우 예후가 좋지 않았다(p<0.05). 결론: 완전절제가 가능한 전이성 폐암에 대한 폐절제술은 만족할만한 생존율을 보였으며, 특히 양측의 다발성 전이가 있는 경우 예후가 불량함을 보였다. 하지만 각 종양별로의 치료성적 및 예후에 관한 보다 많은 경험과 추적관찰이 필요하겠다.

A 78-year-old man underwent laparoscopy-assisted total gastrectomy for gastric cancer (pT3N0M0). Multiple port sites were used, including a 10 mm port for a videoscope at the umbilical point and three other working ports. During the six-month follow-up evaluation, a 2 cm enhancing mass confined to the muscle layer was found 12 mm from the right lower quadrant port site, suggesting a metastatic or desmoid tumor. Follow-up computed tomography imaging two months later showed that the mass had increased in size to 3.5 cm. We confirmed that there was no intra-abdominal metastasis by diagnostic laparoscopy and then performed a wide resection of the recurrent mass. The histologic findings revealed poorly differentiated adenocarcinoma, suggesting a metastatic mass from the stomach cancer. The postoperative course was uneventful, and the patient completed adjuvant chemotherapy with TS-1 (tegafur, gimeracil, and oteracil potassium). There was no evidence of tumor recurrence during the 50-month follow-up period.
