The incidence of the bronchial rupture following blunt chest trauma has increased gradually with the increases of traffic accident and mechanization. We have experienced the 3 cases of the bronchial rupture following blunt chest trauma. The first case was a 38 year old man who was compressed into a blank wall by fork-lift. He complained of severe dyspnea with air leak through the chest tube and right pneumothorax with collapsed lung was seen in his chest X-ray film after closed thoracostomy. Emergency bronchoscopy showed disruptions of the right upper lobar bronchus and the membranous portion of the intermediate bronchus. The second was 8 year old boy who was sustained a crushing chest injury by bus. He also complained of severe dyspnea with air leak through the chest tube and right pneumothorax with collapsed lung was seen in his chest X-ray film after closed thoracostomy. We performed the computed tomogram of the chest and found the bronchial rupture at the distal portion of the right main bronchus. The third case was 40 year old male who was sustained a crushing chest injury by in-car accident. He complained of mild dyspnea without air leak through the chest tube and the left lung was well expanded in his chest X-ray film after closed thoracostomy. Bronchoscopy showed disruption of the 6th cartilaginous portion of the left main bronchus. Emergency bronchoplasties were performed with interrupted end-to-end anastomosis in all cases. Postoperative air leak occurred for 7 days in the third case. Others were uneventful.

Uterine cervical cancer is the most common malignancy in Korean women. In spite of recent development of early diagnostic and therapeutic modalities, about 40% of treated patient will develop relapse. So more aggressive local treatment such as more extensive surgery and higher radiation dose and administration of systemic chemotherapy will promote the curability but treatment related complications cannot be avoidable. We used 22 cases of early cervical cancer, treated with surgery and post-operative radiotherapy, clinical data of these patients were analyzed to determine relationship between clinical parameters and final outcome. Three out of 22 cases revealed relapse and one patient showed rectovaginal fistula and another patient showed small bowel obstruction and the other patient showed rectal obstruction. Two out of three recurrence were stage IIa and the other one case was stage Ib adenocarcinoma with lymphovascular involvement. Nineteen out of 22 cases were followed without remarkable side effect or treatment related complication or sequelae. We concluded that out treatment policy was safe and effective to eradicate high risk postoperative cervical cancer with acceptable side effects or complication.

The stereotactic radiosurgery using ionizing radiation of high energy is a technique for exadicating intracranial small tumors, which are inaccessible or unsuitable for open surgical technique. For such a small field radiosurgery, TLD or film dosimetry is essential. The three dimensional dose planning of radiosurgery was performed with dose planning computer system (Therac 2300). The target dose distribution and its error according to patient position were discussed. And were measured of circular cone which specially designed in our Hospital. The position error of Rando Phantom compared with CT were 0.4 mm in the AP-LAT section and in the AP-VERT section, 1.0 mm in the AP-VERT 45°section. The ratio of accuracy of the gantry and couch rotation were 1.5 mm diameter for central axis of 18MeV linear accelerator. Our study suggested that radiosurgery of small field in out department will be appropriate for clinical application.

Total 55 patients with nonsmall cell lung cancer treated with radiation therapy at Department of Therapeutic Radiology, Yeungnam University Hospital, between May-1 1986 and April-30 1993 were retrospectively analyzed by clinical characteristics, failure patterns follow up duration and survival ratio according to prognostic factors. Obtained results were as follows : 1. Male to female ratio was 17.3 2. Sixth and seventh decades were predominant age group. 3. The patients were 8 in stage I-II, 34 in stage IIIA, 13 in stage IIIb, respectively. 4. Forty five patients out of 55 were squamous cell carcinoma. 5. Primary tumor were originated from upper lobe bronchi predominantly. 6. The size of the primary tumor, lymph node involvement and the degree of differentiation were important in evaluation of prognosis. 7. In conclusion, for patients with poor prognostic factors systemic chemotherapy and multidisciplinary approach were recommended for better treatment outcome and improvement of survival.

In recent years there has been a growing interest in all forms of rotational therapy, and many different types of therapy machines designed for this kind of treatment have become available. To the medical radiation physicist, the dosimetry of rotation therapy has presented a number of interesting problems, and much useful work has been published on the basic date of dose distribution and dosage calculation. The setting dose for ARC therapy were obtained by computer calculation and measurement with cylindrical phantom. Authors compared computer calculation with measured value. And in ARC therapy, the region of maximum dose in shifted from the tumor center. The extent of shift was analyzed by isodose distribution for ARC therapy techniques.

Bone metastases represent an important and frequent clinical problem in patients with advanced cancers. Especially, painful bone metastases are common features in these patients. Radiotherapy is an effective tool for palliative aim of painful metastatic osseous lesions. Various treatment results have been previously reported. The present retrospective study was aimed to evaluate the efficacy of palliative irradiation on pain relief, with the goal of selecting appropriate irradiation dose schedule. Radiotherapy consisted of 5 times a week with a various fractional dose between 180 and 400cGy. The response of pain relief and the survival time after completion of radiotherapy are related to total dose and most of the patients have shown a similar response by the end of radiotherapy. The higher dose and the more aggressive multimodality treatment, the better pain control and the longer survival time.

Radiotherapeutically, nasopharyngeal caner is an important disease in Korea. Because of its blind anatomic location, early detection is relatively uncommon. Clinically, most of cases are locally advanced and nodal involvements are common. Recently better understanding of nature of the disease and improvement of radio – therapy technique permit better treatment result, including locoregional control and survival rate, and minimal normal tissue damages comparing with previously published date. We analyzed 31 patients of pathologically proven and previously untreated naso – pharyngeal carcinoma with different treatment techniques, retrospectively. Minimal and maximal follow up period of the survivor is 6 months and 68 months, respectively. Thirteen patients with squamous cell carcinoma are included in this analysis. The median age is 49 years (range from 20 to 64 years). Twenty two patients are stage III. Eleven patients are treated with radiotherapy alone and 20 are treated with combined modalities treatment. The degree of response after radiotherapy are categorized by 3-classes, i,e. complete response, partial response. In spite of similarities of complete response rate and 1-year survival rate between two different treatment techniques, those patients with undifferentiated carcinoma appear to benefit from the adjuvant chemotherapy. In addition, systemic failure is more suggest that adjuvant therapy in the radiotherapeutic management of nasopharyngeal cancer needs additional research according to histologic types and future extensive clinical trials.
