Soft-tissue sarcomas account for 1% of all solid tumors. Of these, less than 15% will occur in the retroperitoneum. Late diagnosis and large tumor size make retroperitoneal sarcomas difficult to resect. Resection with wide margins in all directions is rarely possible owing to proximity to vital structures. Radiation therapy is limited in dosage and, as with chemotherapy, has only been successful in a limited number of cases. These problems result in a poor prognosis. A series of patients with retroperitoneal sarcoma was reviewed with a focus on issues of surgical management and prognostic factors. A retrospective analysis of 12 patients with retroperitoneal sarcomas who had undergone operations at the Department of Surgery, Inje University Paik Hospital, Seoul, from 1980 through 1996 was performed. The mean age of the 10 adult patients was 51 years; the male-to-female ratio was 2:1. Eighty-three percent of the patients presented with an abdominal mass. The mean diameter of the tumors was 18.3 cm. Leimyosarcomas(33%) and liposarcomas(25%) comprised the majority of the histologic types. The tumor grades were I, II, and III in 3 cases each. Resection of the tumor was possible in 75%(9/12) of the cases, although 17% of the resections were incomplete. Resection of adjacent organs was required in 66% of the cases. The resectability rose from 60% in 80s to 86% in 90s, with no statistical significance, possibly due to the small number of cases in this series. There was no postoperative morbidity or mortality. Actuarial 1-, 3-, and 5-year survival rates after resection were 75%, 60%, and 30%, respectively. Four of the 7(57%) patients who underwent complete resections had recurrence 3 to 33 months after surgery; this was notable for grade II or III tumors only. Two patients with grade I tumors are alive 65 and 102 months respectively after complete resection and show no evidence of the disease. One patient who underwent an incomplete resection of the tumor died 50 months after the operation. Only the tumor grade was a significant prognostic factor(p=0.0207). In conclusion, a wide en-bloc resection of a retroperitoneal sarcoma with a clear margin in all directions is a prerequisite for long-term survival. Aggressive follow-up for the first 3 years after a complete resection of a high-grade tumor is justified.

BACKGROUND : The incidence of breast cancer has steadily increased through the years. The establishment of the cause of breast cancer plays an important role for the diagnosis, management and prevention of breast cancer. METHODS : We analysed 241 cases of breast cancer that were treated during the 13 years from January 1985 to December 1997 at the Department of General Surgery, Inje University Paik Hospital, Seoul. RESULTS : The peak incidence of breast cancer was in the 5th decade (100 cases, 41.5%). The most common age of menarche ranged from 14 to 20 years (89.9%). The most common age of first full-term delivery ranged from 25 to 29 years (54.5%). The normal group was the most frequent body mass index (156 cases, 65.8%). The most common chief complaint was a painless palpable breast mass (166 cases, 68.9%). Most patients (181 cases, 75.1%) visited the hospital within 6 months of developing symptoms. The upper outer quadrant was the most frequent location for breast cancer (146 cases, 60.6%). The most common type of operative technique was a modified radical mastectomy (225 cases, 93.4%). The most common size of the breast mass ranged from 2 to 5 cm (151 cases, 62.7%). A pathologically positive axillary lymph node was present in 122 cases (52.4%). The predominant type of pathological classi fication was invasive ductal carcinoma (215 cases, 90.7%). According to the TNM system, the most common stage was stage II (161 cases, 66.8%). The five-year survival rates for the patients in stages I, II, III were 96.7%, 82.2%, 68.9%, respectively. CONCLUSIONS : We conclude that women with mass or mass-related symptoms needed more careful evaluation and aggressive approaches for discovering breast cancer.
