Primary chest wall tumors originate from soft tissue, bone or cartilage of the chest wall and it comprises 1∼2% of all primary tumors. Resection of tumor is often indicated for chronic ulceration or pain, and long-term survival might be achieved after surgery depending on the histology and the surgical procedure. Material and Method: Retrospective study of 125 primary chest wall tumors (86 benign, 39 malignant) operated between Sep. 1976 to Mar 2001 were reviewed and their clinical outcomes were analyzed. Follow-up data were collected at the outpatient clinic. Result: All patients with benign tumors were treated by excision without recurrence or death, and most malignancies were treated by wide resection. Malignant fibrous histiocytoma and chondrosarcoma constituted 46.2% of the malignant neoplasm. There was no operative death. The overall 3-year survival for patients with primary malignant neoplasm was 76.0%, and the 10-year survival was 60.5%. All deaths were disease-related and the tumor recurred in 11 patients. There was no significant difference in survival between patients with resection margins less than 4 cm and those with resection margins greater than 4 cm. Conclusion: Chest wall resection offers excellent results for benign chest wall tumors and substantial long-term survival for malignant diseases. Safe resection margin of 4 cm or more did not correlate with the survival rate although the tumor recurrence correlated with poor survival.

Background: Several trials have reported on whether adjuvant chemotherapy for resected stage IB non-small cell lung cancer is needed. The aim of our study was to investigate prognostic factors for recurrence to help identify patients who should receive adjuvant chemotherapy. Material and Method: We reviewed the cases of 48 stage IB non-small cell lung cancer patients between 1997 and 2006. Disease-free survival and overall survival rates were calculated by the Kaplan-Meier method. Univariate analysis was performed with the log rank test and multivariate analysis was done using Cox's proportional hazard model. Result: The median follow-up time was 48 months. The overall survival rate was 55.9%, and the disease-free survival rate was 48.6%. Of 8 variables, two factors, visceral pleural invasion and Iymphovascular invasion, were prognostic factors of disease-free survival (univariate analysis). Visceral pleural invasion was a significant prognostic factor in multivariate analysis, and overall survival in com-pared one or more variable such as visceral pleural invasion or, and lymphovascular invasion with the other variables. Conclusion: Visceral pleural invasion was identified as a poor prognostic factor and it may help select which patients will benefit from adjuvant chemotherapy in addition to more comprehensive follow-up.
To eveluate the risk factors which are related to recurrence of ischemic stroke, we selected subjects who were admitted to YNUH due to recurrent stroke and compared their risk factors with non-recurred group who suffered from single ischemic stroke. In the subjects, 55 of them are men and 22 were women and in the non-recurred groups, 84 of them were men and 40 were women, Subject's age ranged from 29 to 85 years(Mean 62, 5years), and non-recurred group's age ranged from 27 to 90 years(Mean 60, 7years), Peak incidence of ischemic stroke is in the 7th decade in both groups. Age and sex are not, statistically significant for recurrence of ischemic stroke. The patient's history of diabetes mellitus, myocardial infarction, atrial fibrillation, transient attack and type or site of ischemic stroke had no significant effect statistically on the recurrent ischemic stroke. However, when the patient had previous history of hypertension or systolic blood pressure more than 160mmHg and diastolic more than 95mmHg, there was substantial difference(P<0.05) between the two group in the recurrence of ischemic stroke. According to the above results, hypertension is most likely significant risk factor of the recurrence of ischemic stroke within 2years after initial one. Therefore, adequate treatment of the hypertension is important for the prevention of ischemic stroke. Further study is required for searching other risk factors.

Purpose: The purpose of this study was to evaluate the oncologic outcomes of parosteal osteosarcoma (POS) and to ascertain the fates of patients after local recurrence (LR). Materials and Methods: The authors retrospectively reviewed 22 POS patients with an average follow-up of 114 months (range: 36-235 months). Seven of the 22 patients were referred after LR. There were 17 Stage IB and 5 Stage IIB (G2, 2; dedifferentiation, 3). Tumors were located in the femur (11) and in other locations (11). Initial surgical margins were wide in 10, marginal in 5, and intralesional in 7. Correlations between clinico-pathologic variables and LR and clinical courses after LR were evaluated. Results: The 10-year overall survival rate was 85.7%. Three (14%) patients developed distant metastasis and all of them succumbed to the disease. Nine (41%) patients developed LR. Tumor location, resection type, and surgical margin were found to be correlated with LR. At final follow-up, 7 of the 9 patients that experienced local failure achieved no evidence of disease. Conclusion: A substantial risk of misdiagnosis exists, especially for POS in other than a femoral location. Recurrent tumor re-excision is possible in most cases; however, patients with an aggressive recurrence pattern deserve special attention.
Fifty patients with residual, unresectable or recurrent rectal cancer were treated with external irradiation using a 6-MV linear accelerator at the Division of Therapeutic Radiology, Department of Radiology, Kangnam St. Mary's Hospital, Catholic University Medical College during the period of April 1983 to December 1987. This paper describes the results of a retrospective analysis of the results of external irradiation for the residual, unresectable and recurrent rectal cancer in 46 patients. Four patients were lost to follow-up. Of the 46 patients, $18 (39\%)$ presented with unresectable primary lesions and $28 (61\%)$ with residual or recurrent rectal cancer. In $93\%$, the pathologic diagnosis was adenocarcinoma. Resonse to irradiation was observed in $22 (73\%)$ out of 30 patients who were treated for pain, $12 (86\%)$ out of 14 patients who were treated for mass, and $17 (77\%)$ out of 22 patients who were treated for bloody discharge. The actuarial postoperative 2-year and 3-year survival rates in recurrent and unresectable patients were $43\%$ and $22\%$, respectively. However, the post-RT 2-year survival rate was $13\% (6/46)$.

Purpose: To assess the usefulness of early stabilization for initial shoulder dislocation which is indicated in some patients by comparing the arthroscopic findings and the outcomes of Bankart repair in the initial and recurrent dislocation. Materials and Methods: The study was performed on 16 cases of initial dislocation and 44 cases of recurrent dislocation. The follow-up period was 25 months in the initial dislocation group and 28 months in the recurrent group. Bankart lesion and the adjacent tissues were compared, and the results were evaluated by the Rowe rating scale. Results: Detached labrum and capsular ligament of the initial dislocation group were elastic and unretracted. While in the recurrent dislocation those were inelastic, and displaced and adhesive in many cases. The outcomes were mean 95 points in the initial group and 91 points in the recurrent group. In the initial group, apprehension was detected in only 1 case(6%). In the recurrent group, instability was detected in 4 cases(9%). Conclusion: Our data suggest that Bankart lesion in the initial dislocation can be repaired readily by surgery, the recovery is efficient, and the recurrence would be reduced. Thus, in active young sports lovers as well as athletes, early stabilization surgery for initial shoulder dislocation may be more helpful.

Purpose: The purpose of this study was to analyze the results of treatment and prognosis of Marjolin's ulcer compared with primary squamous cell carcinoma. Materials and Methods: Fourteen patients treated for Marjolin's ulcer were analyzed. Twenty patients with primary squamous cell carcinoma treated during the same time period was the control group. Mean age was 61.2 years. There were 24 males and 10 females. The locations, TNM stages, histological grades, recurrence, metastasis, and survival rate were analyzed and compared between two groups. Results: The mean follow-up period was 54.8 months (range, 12-168 months). Local recurrences were found in 6 cases, 5 ones in Marjolin's ulcer patients, and one case in primary squamous cell carcinoma patients. The mean time interval between the initial presentation and occurrence of local recurrences was 9 months (range, 2-20 months). There were 6 metastases. 2 (14.3%) metastases were found in Marjolin's ulcer patients, and 4 (20.0%) metastases in primary squamous cell carcinoma patients. Total events (metastasis or local recurrence) were found in 10 pateients, 6 of them in Marjolin's ulcer group, and the remaining four in primary group. 5-year disease-free survival rate was 64.3% in Marjolin's ulcer group and 95.0% in primary squamous cell carcinoma group. Conclusion: Squamous cell carcinomas originating as Marjolin's ulcers revealed higher recurrence rate and lower survival rate despite of aggressive treatment. Therefore, new treatment modalities should be developed for improving outcomes.

This paper is a review of our experience with radical resection for cancer of the oral cavity with particular emphasis upon the value of myocutaneous(i.e., musculocutanous) flaps employed in the surgical reconstruction in patient survival. During the past 15 years, 98 patients underwent resection of cancer arising in the oral cavity and oropharynx. Of these, 14 had composite resections in which the mandible was not sectioned, and 4 underwent en bloc resections without neck dissections in the face of post-radiation recurrence. When these excluded, 84 patients who underwent COMMANDO procedures with or without myocutaneous flaps were suitable for analysis of recurrence and survival according to the various surgical technics employed. 1) According to the surgical technic, there were 24 standard COMMANDO procedures in whom no regional or myocutanous flap was used; 12 patients who underwent reconstruction employing a forehead flap; 19 patients in whom a posterior cervical 'nape' flap was employed; 27 patients who underwent myocutaneous or osteo-myocutaneous flap repair; and two patients who had double flap repair. 2) The uncorrected two-year disease free survival was 41% for standard COMMANDOs, 17% for forehead flap COMMANDOs; 35% for nape flap COMMANDOs; and 35% for myocutaneous flap COMMANDO procedures. 3) The two-year disease-free survival by Stage was 100% in Stage I, 45% in Stage II, 41% in Stage III, and 18% in Stage IV. 4) When myocutanous flaps cases were compared with Group I, comprised of matched historical controls including both Standard COMMANDOs and those who had undergone regional flap repairs(that is, forehead and nape flap COMMANDOs)there was no difference, both groups showing a 40% 2-year disease-free survival. 5) When musculocutanous flap cases were compared with Goup II, which was composed of matched historical controis limited to patients who had undergone regional flap repairs(that is, forehead and nape flap cases only)there was no difference, both groups showing a 27% 2-year desease-free survival. 6) When musculocutanous flap cases were compared with Group III, composed of patients who had undergone classic COMMANDO procedures without any sort of flap repair, there was a striking difference; the patients undergoing MC flap repair showed 50% 2-year disease-free survival, whereas the classic COMMANDO cases showed a 25% survival free of disease. 7) Locoregional recurrence was also evaluated in the four categories; for standard COMMANDO cases it was 25%, for nape flap cases 26% ; for forehead flap cases, 33%, and for the musculocutaneous flap cases, the lowest recurrence rate, 22%. These results are of particular significance in view of the fact that the proportion of advanced cases(Stage III and IV)in each category was 67% of standard cases, 79% of nape flap patients, 100% of forehead flap cases, and 96% of musculocutaneous flap cases.
Purpose : To improve treatment modality and results by analysis of clinical characteristics, local control, survival and recurrence rate in limited stage small cell lung cancer. Materials and Methods : patients with limited stage small cell lung cancer were treated with combined radiation and chemotherapy from Feb. 1986 to Dec. 1992 at the National Medical Center We followed up on 21 patients ($81\%$), who were mostly irradiated with 4,000-5.000cGy ($75\%$ of all Patients) in the results by the analysis retrospectively. Survival rate was evaluated by the Kaplan-Meier method Results : Mean survival of irradiated patients with limited small cell lung cancer was 12 months. 1-rear and 2-rear survival rate were $65.3\%$ and $15.4\%$ Tumor response rate and median survival after combined chemotherapy and irradiation were the following: $50\%$ and 15 months of complete response, and $23\%$ and 11 months of partial response respectively. Response rates by radiation dose were $66\%$ for below 4,000cGy $69\%$ for between 4,000-5,000cGy and $86\%$ for above 5,000cGy. 21 of all patients showed treatment failure($81\%$) which as appeared 9 of local failure.9 of distant failure and 3 of local and distant failure. Conclusion : Local response rate after induction chemotherapy alone in limited stage of small cell lung cancer was $54\%$. Furthermore it was increased to $73\%$ after adding of radiation. We have to increase radiation dose above 5,000cGy and need to try new effective chemotherapy agents for the improvement of local control and survival rate and also will try concurrent chemoradiotherapy in near time.

Background : Small-cell carcinomas of lung have a tendency for rapid growth and early wide metastasis. Despite the high response rates of combination chemotherapy alone or with radiotherapy, the overall long-term survival rate is very disappointing. According to autopsy findings, the common cause of failure is local recurrence in the primary cancer site. Therefore, surgical resection with combined chemotherapy has recently been attempted for very early stage small-cell carcinomas of the lung. Methods : 10 patients (TNM I & II: 5 cases each) undergoing surgical resection for small-cell carcinomas of the lung were treated with adjuvant chemotherapy in an attempt to prolong survival. Of these, 9 patients received chemotherapy, and a retrospective study for survival undertaken (Kaplan-Meier analysis). Results : The median survival time was 26 months, and the 2- and 5-year survival rates were 68.6 and 46.7%, respectively. If the 1 patient not having undergone chemotherapy was excluded, the 2-, 5-year survival rates were 76.2 and 50.8%, respectively? No difference in the survival rate was seen between patients with TNM stages I and II. Conclusion : Adjuvant chemotherapy after surgical resection results in prolonged survival for patients with TNM stages I and II small-cell carcinomas of the lung.
