Sebaceous carcinomas of the eyelids are uncommon but lethal tumors. Lesions are usually seen in the elderly, predominantly women. The meibomian glands of the tarsus are the most frequent site of origin. Less commonly, the tumor arises in other sebaceous glands, e.g., the gland of Zeis, eyebrow or caruncle. Regardless of the location, sebaceous malignancies must be considered aggressive neoplasms with a potential for regional and distant metastasis. Diagnosis may be difficult, given the low incidence and inconsistencies in histopathologic classification. Treatment requires wide surgical excision with removal of involved regional lymph nodes and exenteration is reserved for those patients with orbital involvement or diffuse intraepithelial neoplasia. Opinions are divided regarding the use of postoperative irradiation or chemotherapy. Recently we experienced 46-year-old male patient with a 12-month history of painless, firm nodule and conjunctivitis due to sebaceous carcinoma of the left upper eyelid. After surgery, serial sections of the entire conjunctiva and eyelids showed a positive cut margin in medial and lateral border. We report herein this patient that supports irradiation as the postoperative treatment of these tumors in selected patients with a review of literatures.

The acute effects of variable dos rates to total body irradiation (TBI) were investigaed with 600 cGy of single exposure in the mice as a preclinical model. Total 80 mice (ICR) were used. Twenty of which sewed as controls, receiving no irradiation. All irradiated mice showed a universal decline in their weight and white blood cell count. The degree of weight loss and leukopenia were similar at 3 different dos rate but slightly prominent with 15 cGy/minute group. The degree of recovery among the groups showed no dose rate dependence. Our results suggest that TBI with 15 cGy/mimute may be applicable for clinical therapy with careful evaluation of patient's condition.

During the period between March 1979 and August 1986, 177 patients with carcinoma of the esophagus were treated with radiotherapy in the Department of Therapeutic Radiology, SNUH. Among these, 25 patients who had incomplete treatment were excluded. So a retrospective analysis was undertaken of 152 patients who were treated by curative radiotherapy. More than $80\%$ showed response: Complete remission $(22\%)$, partial remission $(63\%)$ and no response $(15\%)$. The overall two-year and five-year actuarial survival rate were $22.9\%\;and\;13.3\%$ respectively. Prognostic factor was analyzed by its site, size, T stage, and tumor response. Patients with the best five-year survival rate were those who had the tumor no more than 5cm in length $(17\%)$ or confined to the upper third of the esophagus $(20.6\%)$. Complete responders had $34.3\%$ of 5-year actuarial survival, but no responders had $0\%$ of survival.

Radiation therapy has been used as adjuvant therapy or primary treatment for inoperable, remnant or recurrent cancer. Many authors reported good palliation effect by external irradiation or interstitial therapy, but the report of intracavitary irradiation for recurrent, inoperable rectal cancer is very rare. We experienced a case of recurrent adenocarcinoma of rectum along fistula tract after laparotomy and postoperative radiotherapy who achieved very good palliation by intracavitary irradiation. Even though we have only good palliation without impressive survival improvement in this case, we hope that this technique may achieve good local control In other similar patients.

To assess the result of radiation therapy for fifteen fears experience, a total of 125 cases of pathologically proven supraglottic laryngeal cancer had been analyzed according to patient survival retrospectively. All the patients had been treated with radiation therapy in curative aim using Co-60 teletherapy machine. The results are as follows ; 1. According to AJCC staging, five year survival rate was $58.3\%$ in stage I, $44.4\%$ in II, $31.8\%$ in II, and $28.6\%$ in IV. 2. According to T-staging, five year survival rate was $57.1\%$ in T1, $40.5\%$ in T2, $34.0\%$ in T3, and $19.0\%$ in T4. 3. According to N staging, five year survival rate was $43.5\%$ in negative node group and $26.8\%$ in positive node group. 4. According to the histologic grade, the better in differentiation, the more in number of cases and the better in prognosis. 5. In summary, five year actuarial survival rate was $37.3\%$ and ten year surrival rate was $34.2\%$, and ten year survivors totalled 16 cases.

To access the result of radiation therapy for 8 years experiences, 21 patients who were treated with superior vena cava syndrome had been analysed according to dose fractionation and total dose. The results are as follows; 1. In high fractionate dose group, six of eleven patients $(54.5\%)$ exhibited relief of symptoms in 1-2 days, and additional three patients of nine $(81.7\%)$ within 34 days, while standard fractionated dose treatment is not effective to achieve initial relief of symptoms. 2. Graded response by total dose was correlated with total dose rather than dose fractionation. 3. Overall one year survival rate with superior vena cava syndrome was $9.1\%$ and mean survival was 4.2 months.

Objectives: We compared the therapeutic response, the treatment-related toxicity, and the improvement of subjective symptoms between the chemotherapy alone group and the western-oriental combined treatment group and evaluated the role of oriental medicine for the improvement of chemotherapy-related toxicity in the advanced gastric cancer and hepatocellular carcinoma. Methods: We evaluated 36 gastric cancer or hepatocellular carcinoma patients(chemotherapy alone group 25 patients, combined treatment group 11 patients) who had been treated in Wonju Christian Hospital and Hana Hospital of Oriental Medicine between June 1999 and October 2000. Enrolled patients' general medical records, results of laboratory and imaging studies, treatment-related toxicities, and subjective symptoms were recorded regularly according to the planned protocol. Therapeutic responses were estimated according to the WHO response criteria and the changes of tumor marker value such as CEA, CA 72-4 and AFP. Results: 1. There was no significant difference of therapeutic response by the WHO response criteria between the two groups(p=.459). 2. There was a significant decrease of tumor marker value in the combined treatment group compared to the chemotherapy alone group(p=.023). 3. There was less comprehensive treatment-related toxicity in the combined treatment group compared to the chemotherapy alone group(p=.037), but there was not a significant difference of comprehensive improvement of subjective symptoms between the two groups(p=.091). Conclusions: Based on the above results, we could expect the possibility of improvements in therapeutic response and treatment-related toxicity with the western-oriental combined anticancer treatment.

Seventy-nine patients with carcinoma of maxillary antrum treated at the department of therapeutic radiology, Kosin Medical Center, between June 1980 and December 1980 were analyzed retrospectively for survival rate and treatment failure. Forty-three patients were treated with radiotherapy alone and thirty-six patients were treated with combination of surgery and radiotherapy. The overall 5 year survival rate was 32$ \% $, patients that were treated with radiotherapy alone had a 5-year survival rate of 23$ \% $, and patients who were treated with combination of surgery and radiotherapy had a 5-year survival rate of 42$ \% $. 54 patients(68.4$ \% $) failed to be cured. Among these 54 patients,37 patients(08.5$ \% $) had only locoregional failure, 16 Patients(29.6$ \% $) had locoregional failure and distant metastases and 1 patient had only distant metastasis. From above study combination of surgery and radiotherapy might be a better treatment modality for carcinoma of the maxillary antrum.

Carcinoma of extrahepatic biliary tract is slow growing tumor but curative resection is rarely successful. Radiation therapy has been introduced for enhancing palliation and possible longterm survival. We treated a case of advanced extrahepatic biliary tract carcinoma with high dose rate remote afterloading system through T-tube as a initial irradiation postoperatively. We hope that this treatment may affect not only ennancing palliation and better quality of life but also in local tumor control.

Purpose : Patients with esophageal cancer treated with surgery plus postoperative radiotherapy or radiation alone were retrospectively analyzed. Method : From August 1980 to June 1992, 93 patients who were treated with 30 Gy or more in the Department of Therapeutic Radiology were evaluated. Median age was 59 years. Ninety one were male and remaining 2 were female. Patients with stage II, III and IV disease were 25, 62 and 6 respectively. Thirteen of the tumor were located in upper one third, 56 in middle one third and 24 in lower one third. Forty three patients had tumors 5cm or less in size and remaining 50 had greater than 5cm. Of those 93 patients, 41 were treated with surgery plus postoperative radiotherapy and 52 with radiation alone. Dose of radiation ranged from 34 to 66.6 Gy. Follow up period was 12 to 61 months. Results : Stage of the tumor was the most important prognostic factor of the evaluated factors. Median survival for entire group of patients was 12 months. Median survival for patients treated with surgery plus postoperative radiotherapy and radiation alone were 15 and 10 months, respectively. There was no difference of 2 year survival. Median survival was 21 months for Stage II and 10 months for Stage m disease. In Stage II disease, that was 21 months for postoperative group and 17.5 months for radiation alone group. Five year survival were $27.5\%$ and $9\%$, respectively. Conclusion : This study showed that the result of surgery plus postoperative radiotherapy was not different from that of radiation alone despite of slightly longer median survival in postoperative group. Also stage of the disease was the most important prognostic factor.
