Hypopharyngeal cancer have shown poor prognosis though various treatment modalities were developed for several decades. Therefore current trend in managing hypopharyngeal cancer is organ preservation therapy to improve patient's quality of life. Recently, surgery via robotic surgical system in genitourinary surgery improved minimal invasive technique and reduced morbidity dramatically. Hypopharyngeal cancer treatment using Transoral robotic surgery (TORS) in treating lesions of hypopharynx could reduce the morbidity and achieve organ preservation.

Purpose : The aim of this study was to determine if postoperative adjuvant chemotherapy (CT) alone and concurrent chemoradiation (CCRT), following radical surgery, improved the disease free survival (DFS) and overall survival (OS) in rectal cancer AJCC stage II and III patients. Materials and Methods : A total of 144 patients with AJCC stage II and III rectal cancer who had had radical surgery between 1989 and 1999 were included in the study. Of these patients, 72 had been treated with postoperative CT, and the other 72 with postoperative CCRT. The chemotherapy regimen consisted of oral UFT on a daily basis for $1\~12$ months (median 12 months) or 5-FU ($500\;mg/m^2$ for 5 days) intravenous (IV) chemotherapy with 4 week intervals for $1\~18$ cycles (median 6 cycles). Radiation of 4,500 cGy was delivered to the surgical bed and regional pelvic lymph nodes area, followed by $540\~1,440\;cGy$ (median 540 cGy) boost to the surgical bed. The follow-up period ranged from 20 to 150 months, with a median of 44 months. Results : The 5-year OS was $60.9\%\;and\;68.9\%$ (p=0.0915), and the 5-year DFS was $56.1\%\;and\;63.8\%$ (p=0.3510) for postoperative CT and postoperative CCRT, respectively. In the stage nm patients, the 5-year OS was $71.1\%\;and\;92.2\%$, and the 5-year DFS was $57.3\%\;and\;85.4\%$ for postoperative CT and CCRT, respectively. The OS was significantly improved (p=0.0379) but the DFS was not with postoperative CCRT compared to the postoperative CT (p=0.1482). In the stage III patients, the 5-year OS was $52.0\%\;and\;55.0\%$, and the 5-year DFS was $47.8\%\;and\;49.8\%$ for postoperative CT and postoperative CCRT. There were no statistically significant differences between postoperative CT and CCRT (p=0.4280 and p=0.7891) in OS and DFS. The locoregional relapses were $16.7\%\;and\;12.5\%$ for postoperative CT and CCRT, respectively. The distant relapses were $25.0\%\;and\;26.4\%$ for postoperative CT and CCRT, respectively. Conclusion : These results showed that postoperative CCRT compared with CT alone improved OS in stage II patients. Although there was no statistical significance, the addition of postoperative RT to CT reduced locoregional relapses compared to CT alone.

Authors performed a stereotactic radiosurgery with multiple noncoplanar convergent photon beams of linear accelerator (NELAC-1018 18 MeV, NEC) using a specially designed Yeungnam localization device for two patients with recurrent glioblastoma multiforme. One patient had 2 cm sized and the other 4 cm sized mass on the CT images. After single session of treatment with 15 and 20 Gy, headache was improved in a few days after radiosurgery with no remarkable untoward reactions. Our experience with these two patients were encouraging and we found that our localization device, which is easily adjustable and inexpensive, could be a valuable tool for stereotactic radiosurgery particularly in the treatment of recurrent brain tumor.

Spontaneous pneumothorax accompanying primary lung cancer is rare and its occurrence as an initial sign of primary lung cancer is much rarer. A few articles on spontaneous pneumothorax accompanying lung cancer have been published in Korea so far. Lung cancers, diagnosed after spontaneous pneumothorax, are usually in advanced stage, so that conservative treatment modalities such as closed tube thoracostomy, chemotherapy, or radiotherapy are the mainstream of the treatment. We experienced a case of local recurrence of primary lung cancer in six months after radical resection and radiotherapy of neoplasm performed immediately after the diagnosis by excisional biopsy of bulla, for which resection and pleurodesis had been done under the impression of spontaneous pneumothorax. In this paper, we report the case and follow-up observation of the patient.

Purpose: The prognosis of stage IV gastric cancer is poor with the 5-year survival rate still being about 10%. We investigated the prognostic factors of stage IV gastric cancer patients who underwent resection. Materials and Methods: A retrospective study of 383 patients with stage IV gastric cancer who underwent surgery in our department between September 1983 to December 2000 was conducted. We classified the 383 patients into two groups: patients surviving 2 years or more (n=77) and those surviving less than 2 years (n=306). Clinicopathologic differences were analyzed between the two groups. We also performed univariate and multivariate analyses of various clinicopathologic factors concerning survival. Results: Statistically significant clinicopathologic differences between the two groups were observed in regard to macroscopic type, distant metastasis, lymph node dissection, curability, and histology. Curability and histology were significant survival factors in 2-year survival. The 5-year survival rate was 5.4% in stage IV gastric cancer. Significant differences in survival among macroscopic type, distant metastasis, lymph node dissection, curability and histology were observed in the univariate analysis. In the Multivariate analysis, Curability, lymph node dissection, and histology were significantly beneficial factors for survival. Conclusion: Lymph node dissection, curability, and histology were independent prognostic factors in stage IV gastric cancer, and radical treatment is recommended to improve survival.

A 54-year-old male patient who was diagnosed with advanced gastric cancer underwent a distal gastrectomy, D2 lymph node dissection, and adjuvant chemoradiotherapy. After a year, in a follow-up PET-CT, lymph node metastases were observed in the neck and abdomen, and therefore, the patient underwent chemotherapy. After treatment, the follow-up PET-CT revealed a growth of the posterior neck lymph node. Thus, an excisional biopsy was performed, and the growth was diagnosed as metastatic adenocarcinoma. Therefore, the patient received chemotherapy with FOLFIRI. Another follow-up PET-CT after chemotherapy revealed a growth in the right inguinal lymph node, and the patient underwent salvage radiotherapy for this lesion. The PET-CT taken for the response evaluation showed no evidence of further metastasis of the lymph node. We hereby report a case of advanced gastric cancer with neck and inguinal lymph node recurrence showing complete remission after palliative chemotherapy and salvage radiotherapy.

A 69-year old man presented with severe epigastric pain for 1 day. He had early gastric cancer at the antrum and underwent a distal subtotal gastrectomy and Billorth II gastrojejunostomy one month later without any post-operative complications. Radiologic examination revealed a large amount of retroperitoneal free air formation. Because of unremitting pain and unstable vital sign, exploratory laparotomy was followed. During the operation, a perforated duodenal diverticulum at the posterior wall of the 2nd portion of the duodenum was identified. He underwent diverticulectomy and primary closure. He was discharged on the 18th post operative day and has been followed up without any evidence of comlpication for several months.

Local excision and axillary dissection followed by radiation therapy to the breast has been shown to achieve equivalent local control and survival as mastectomy in an prospective randomized trials. We analyzed 28 cases of early breast cancer in order to evaluate the therapeutic effects of conservative surgery and definitive radiotherapy in the management of early breast cancer as possible alternative of simple mastectomy, retrospectively. Obtained results were as follows : 1. Treatment related acute side reactions are more prominant in the case of chemoradiotherapy group than radiotherapy alone group. 2. There were no cases of primary, regional or systemic failures on the last follow up examination. 3. Cosmetic results after treatment were satisfactory in 26 cases out of 28 cases on the last follow up examination. 4. There were no demonstrable differences of tumor control and cosmetic results between the treatment groups. Although, these results suggested that definitive radiotherapy after local excision would be a possible and desirable alternative instead of total mastectomy in the management of early breast cancers, analyzed cases were too small and follow up period was too short to evaluate the therapeutic effect of primary radiotherapy after local excision, exactly.

Dedifferentiated chondrosarcoma is a most highly malignant variant of chondrosarcoma and approximately 10% of chondrosarcomas dedifferentiated into more anaplastic lesions. In addition to the surgical treatment, adjuvant chemotherapy or radiation therapy has been used but with little success. Thus, the primary treatment remains wide excision and chemotherapy or radiation therapy can be used for palliation. This article shows the case of a dediffderentiated chondrosarcoma occuring in proximal femur after conservative surgical treatment of a low grade chondrosarcoma.
