Recurrence is the most common complication after shoulder instability surgery, and the main causes of the postoperative recurrence of instability are trauma, misdiagnosis, and technical errors. The risk factors of recurrence may be classified as patient related, anatomical or technical. Causes of failure should be thoroughly evaluated by meticulous history taking, physical examination, and imaging studies, and followed by proper treatment of pathologic lesions. Nonoperative treatment should be considered initially in cases of recurred instability after shoulder instability surgery, but if this fails, repeated recurrence is prevented by performing appropriate anatomical reconstruction of ruptured Bankart lesions, capsular laxities, glenoid deficiencies and humeral head bone defects.

Thirty eight women with recurrent breast carcinoma involving chest wall and/or regional lymph nodes after surgery with or without systemic therapy were treated with radiation between 1979 and 1986. Among them, 5 patients were excluded from analysis because of incomplete treatment. The median follow up of survivors was 30 months (randged 1-79 months). Fifteen (45%)patients had their disease confined to the chest wall and eighteen patients had lymph node involvement as some of their locoregional recurrent disease. Within 36 months after the initial treatment, 87% of recurrences manifested themselves. All patients had radiotherapy to at least the site of involvement. In 8 patients, recurrent tumors were treated with complete excision followed by radiation. Of the remaining 25 patients,18 (72%) had complete response (CR) following radiotherapy. The actuarial 3-year survival of all patients following locoregional recurrence was 50% Three year survival was 24% in those 25 patients who had recurrences within 24 months of the initial treatment. For those 8 patients whose recurrences occurred after more than 24 month disease free interval, the 3-year survival was 100%. For those patients with recurrences confined to chest wall alone, 3-year survival was 57% The patients who had lymph node involvement as part of their locoregional recurrences had a 43% 3-year survival. The majority of them developed distant metastases. Those patients who had a CR showed 63% 3-year survival. On the other hand, 1 year survival was only 33% for those patients who had a less than CR. Three patients developed carcinoma of the contralateral breast following radiotherapy. Three year survival following locoregional recurrence was 40% for patients whose initial treatment for their primary breast carcinoma was surgery and adjuvant systemic therapy. For those patients whose primary breast carcinoma was treated by surgery alone, the 3-year survival following locoregional recurrence was 71%. In patients who had subsequent recurrence after radiotherapy, the actuarial survival was 25% at 2 years.
Background: The cause of spontaneous pneumothorax is not yet but it is certain that intrathoracic air comes from ruptured bulla. Video-assisted thoracoscopic surgery(VATS) or open thoracotomy is recommended for thoracic incision in recurrent pneumothorax. However, recurrent rate after bullectomy with the VATS is very high compared to mini-thoracotomy, 3% to 20% and below 2%, respectively. Material and Method: This retrospective analysis was performed on 16 re-operated cases among 446 surgically treated pneumothorax of the 737 cases of spontaneous pneumothorax diagnosed at Yongdong Severance Hospital from Nov. 1992 to June 1997. Result: Among the 446 surgically-treated patients in 737 case of spontaneous pneumothorax, 16 patients underwent re-operation, showing a 3.5% re-operation rate. Male-to-female ratio was 15 to 1 and mean age at initial attack was 20.2 years(ranging from 15 to 50). Mean hospital stay was 6.34 days(ranging from 2 to 20 days) and mean chest tube indwelling period was 4.2 days(ranging from 1-10 days). Median follow-up was 46 months(range 10-66 months). Three different surgical methods were applied : video-assisted thoracoscopic surgery(VAST) in 281 cases, of whom 2 underwent local anesthesia; subaxillary mini-thoracotomy in 159 cases and limited lateral thoracotomy in the remaining 6 cases. Three different re-operative surgical methods were applied ; video-assisted thoracoscopic surgery (VAST) in 6 cases, subaxillary mini-thoracotomy in 9 cases, and limited lateral thoracotomy in the remaining 1 case. The underlying etiological factors of the recurrent pneumothorax after bullectomy were o erlooking type(9) and new growing type(7). Mean recurrent period from previous operation was 1 month for overlooking type and 18 months for new growing type. Conclusion: The underlying etiological factors of recurrent pneumothorax lead to re-operation were new-growing and over-looking type. We need additional treatments besides resecting blebs of prevent the recurrence rate and more gentle handling with forceps due to less damage to the pleura.
To evaluate the relapse pattern and long-term stabilities depanding on surgical methods following orthognathic surgery of Cl III patients, the author selected 24 subjects(10 male, 14 female) operated by SSRO and 26 subjects(10 male,16 female) operated by IVRO. Each subject took four lateral cephalograms : just before surgery(T1), within 48hrs after surgery(T2), 4-8 wks after surgery(T3), 6 month or more after surgery(T4), and the landmarks were digitized. The differences of relapse patterns in each interval between two groups were compared and the significance of correlation among the variables of each group was tested. The obtained results are as follows ; 1. Horizontal early relapse was forward movement of mandible in SSRO group, as compared to the backward movement in IVRO group, and there was a statistical significance between the two groups. 2. Vertical early and late relapses were decreases in anterior facial height in both groups and there was no statistical significance between the two groups. 3. There was a statistical significance in negative correlation between mandibular horizontal late relapse and surgical change of articular angle in SSRO group. 4. There was a statistical significance in negative correlation between amount of mandibular set-back and mandibular horizontal early relapse in both groups.
Purpose : To determine the optimal radiation dose in a localized non-Hodgkin's lymphoma of the head and neck in the treatment setting for combined chemoradiotherapy. Materials an Methods :Fifty-three patients with stage I and II diffuse large ceil non-Hodgkin's lymphoma of the head and neck, who were treated with combined chemoradiotherapy between 1985 and 1998 were retrospectively reviewed. The median age was 49 years, and the male-to-female ratio was approximately 1.6. Twenty-seven patients had stage 1 disease and 26 had stage II. Twenty-three patients had bulky tumors $(\geq5\;cm)$ and 30 had non-bulky tumors (<5 cm). The primary tumors arose mainly from an extranodal organ $(70\%)$, most cases involving Waldeyer's ring $(90\%)$. All patients except one were initially treated with $3\~6$ cycles of chemotherapy, which was followed by radiotherapy. Radiation was delivered either to the primary tumor area alone $(9\%)$ or to the primary tumor area plus the bilateral neck nodes $(91\%)$ with a minimum dose of 30 Gy $(range\;30\~60\;Gy)$. The failure patterns according to the radiation field were analyzed, and the relationship between the dose and the in-field recurrence was evaluated. Results : The 10-year overall survival and the 10-year disease free survival rates were similar at $75\%\;and\;76\%$, respectively. A complete response (CR) after chemotherapy was achieved in 44 patients $(83\%)$. Subsequent radiotherapy showed a CR in all patients. Twelve patients $(23\%)$ had a relapse of the lymphoma after the initial treatment. Two of these patients had a recurrence inside the radiation field. No clear dose response relationship was observed and no significant prognostic factors for the in-field recurrences were identified because of the small number of in-field recurrences. However, for patients with tumors <5 cm in diameter, there were no in-field recurrences after a radiation dose 30 Gy. The 2 in-field recurrences encountered occurred in patients with a tumor $\geq5\;cm$. Conclusion .A dose of 30 Gy is sufficient for local control in patients with a non-bulky (<5 cm), localized, diffuse large cell non-Hodgkin's lymphoma when combined with chemotherapy. An additional boost dose in the primary site is recommended for patients with bulky tumors $(\geq5\;cm)$.
Purpose: The role of radiotherapy in the management of patients with locoregional recurrent cervix cancer after radical surgery were retrospectively analyzed. Methods and materials: Twenty-eight patients treated with radiotherapy for locoregional recurrence after primary surgery for carcinoma of the cervix between 1989 and 1993 were analyzed. The median follow-up of survivors was 15 months (ranged 7-43 months). Eight patients had their disease confined to the vagina and 19 patients($68\%$) had pelvic mass as part of their locoregional recurrent disease. Within 24 months after the initial surgery, $82\%$ of recurrences manifested themselves. All patients had whole pelvic irradiation with or without intracavitary radiotherapy(ICR). Results: Complete response(CR) was achieved in 18 patients($54\%$). Five of eighteen patients($28\%$) with initial CR developed second locoregional recurrence. Response to radiotherapy correlated strongly with tumor volume, site of recurrence and total radiation dose. The overall 2 year survival rate was $43\%$ and the disease free survival was $31\%$. Survival rate was significantly influenced by the factors of interval from operation to recurrence, size and site of recurrent tumor, radiation dose, response of radiotherapy, lymph node status as initial presentation, The principal cause of death was lung metastasis($36\%$). Conclusion: Radiotherapy is an excellent modality for control of locoregional recurrent cervix cancer. To improve local control and survival rate, whole pelvic external radiotherapy in addition to ICR with more than 75.0Gy at the depth of 1.0cm from vaginal mucosa is needed and frequent follow up and early detection of recurrence is suggested as well.

Complete surgical resection is the most effective treatment for pT1/2N1 non-small cell lung cancer, however 5 year survival rate of these patients is about $40\%$ and the major cause of death is recurrent disease. We intended to clarify the risk factors of recurrence in completely resected pT1/2N1 non-small cell lung cancer. Material and Method: From Jan. f990 to Jul. 2003, total of 117 patients were operated for pT1/2N1 non-small cell lung cancer. The risk of recurrence according to patients characteristics, histopathologic findings, type of resection, pattern of lymph node metastasis, postoperative adjuvant treatment were evaluated retrospectively. Result: Mean age of patients was 59.3 years. There were 14 patients with T1N1 and 103 patients with T2N1 disease. Median follow-up time was 27.5 months and overall 5 year suwival rate was $41.3\%$. 5 year freedom-from recurrence rate was $54.1\%$. Recurrence was observed in $44 (37.6\%)$ patients and distant recurrence developed in 40 patients. 5 year survival rate of patients with recurence was $3.3\%$, which was significantly lower than patients without recurrence $(61.3\%,\;p=0.000).$ In multi-variate analysis of risk factors for freedom-from recurrence rate, multi-station N1 $(hazard\;ratio=1.997,\;p=0.047)$ was a poor prognostic factor. Conclusion: Multi-station N1 is the risk factor for recurrence in completely resected pT1/2N1 non-small cell lung cancer.
To examine whether HSV, VZV, H. pylori and Candida that are known to be microorganisms causing ulcerative disease in oral cavity and have the relatively high contigiousness are detected in saliva of patients with RAU and related to the development with RAU, PCR and culture were performed on the saliva of 29 patients with RAU and 29 control subjects who visited the Department of Oral Medicine, Dental Hospital, Chosun University. The results were obtained as follows; 1. HSV DNA was detected in 41.4% patients with RAU, and 55.2% control subjects, however, a significant difference between the two groups was not detected, (P>0.05), and VZV DNA was not detected in both groups. 2. H. pylori DNA was detected in 27.6% patients with RAU, and 48.3% control subjects, however, a significant difference between the two groups was not detected (P>0.05). 3. Candida was cultured in 13.8% patients with RAU, and 6.9% control subjects, however, a significant difference between the two groups was not detected (P>0.05). This results suggest that HSV, VZV, H. pylori and Candida can not be regarded to play a direct role in the development of RAU. Thus it is considered that in future, on a larger sample, also, it has to be examined whether other microorganisms acts as a trigger factor of the development of RAU.

Purpose : Dermatofibrosarcoma protuberans(DFSP) is a rare tumor of the skin with a strong tendency of infiltration to surrounding tissues. Inadequate surgical intervention brings about frequent recurrence and poor prognosis. We attempted to find a guideline for adequate treatment for DFSP. Materials and Methods : Fourteen cases who had been treated in our department since Mar. 1993 and followed up for more than 12 months postoperatively were reviewed. Including nine cases who were transferred from other hospital after recurrence, thirteen cases underwent wide resection. One case was treated by intralesional resection followed by chemotherapy (CYVADIC) due to neurovascular abutment to the mass in the inguinal area. Results : The nine cases who were transferred due to recurrences experienced recurrence in average 1.3(1-2) times and the average period until first local recurrence from primary operation was 11.8(2-24) months. The thirteen cases with wide surgical margin showed no recurrence at the final follow up. One case treated by intralesional resection and chemotherapy showed multiple recurrence and died of the disease due to lung metastasis. Conclusions : From these data, we could find that primary wide resection can be the way of reducing recurrence and metastasis, and the follow up period for the detection of recurrence should be at least two years.

Purpose: To date, anatomical imaging modalities of the pelvis and tumor markers have been the mainstay of surveillance for recurrent ovary cancer. This study aimed to assess the role of $^{18}F$-FDG PET/CT in evaluation of ovary cancer recurrences, especially in comparison with enhanced a and tumor marker CA 125. Materials and methods: 73 patients who had PET/CT scan for restaging of confirmed ovary cancer, and additional imaging with enhanced a of the pelvis within one month were included. CA 125 level was available in all patients. From the PET/CT images, maximum standard uptake values (SUVmax) of suspected recurrence sites were recorded. Confirmation was available through re-operation or biopsy in 26 cases, and clinical assessment with series of follow-up images in 47. Results: PET/CT had 93% sensitivity and 88% specificity for detecting recurrent ovary cancer. Enhanced a of pelvis had sensitivity and specificity of 83% and 88%, and CA 125 50% and 95%. Conclusion: PET/CT has higher sensitivity for detecting recurrent ovary cancer compared to enhanced a though the differences were not significant. PET/CT has significantly higher sensitivity than CA 125. However, the three tests all agreed in only 43% of the recurrence cases, and recurrence should be suspected when any of the tests, especially PET/CT, show positive findings.
