Background: Reoperations on the aortic root or the ascending aorta are being performed with increasing frequency and remain a challenging problem. This study was performed to analyze the results of reoperations on the ascending aorta and aortic root. Material and Method: Between May 1995 and April 2001, 30 patients had reoperations on the ascending aorta and aortic root and were reviewed retrospectively. The mean interval between the previous repair and the actual reoperation was 56 months(range 3 to 142 months). Seven patients(23.3%) had two or more previous operations. The indications for reoperations were true aneurysm in 7 patients(23.3%), prosthetic valve endocarditis in 6(20%), false aneurysm in 5(16.7%), paravalvular leak associated with Behcet's disease in 4(13.3%), malfunction of prosthetic aortic valve in 4(13.3%), aortic dissection in 3(10%), and annuloaortic ectasia in 1(3.3%). The principal reoperations performed were aortic root replacement in 17 patients(56.7%), replacement of the ascending aorta in 8(26.7%), aortic and mitral valve replacement with reconstruction of fibrous trigone in 2(6.6%), patch aortoplasty in 2(6.6%), and aortic valve replacement after Bentall operation in 1 (3.3%). The cardiopulmonary bypass was started before sternotomy in 7 patients and the hypothermic circulatory arrest was used in 16(53.3%). The mean time of circulatory arrest, total bypass, and aortic crossclamp were 20$\pm$ 12 minutes, 228$\pm$56 minutes, and 143$\pm$62 minutes, respectively Result: There were three early deaths(10%). The postoperative complications were reoperation for bleeding in 7 patients(23.3%), cardiac complications in 5(16.7%), transient acute renal failure in 2(6.6%), transient focal seizure in 2(6.6%), and the others in 5. The mean follow-up was 22.8 $\pm$20.5 months. There were two late deaths(7.4%). The actuarial survival was 92.6$\pm$5.0% at 6 years. One patient required reoperation for complication of reoperation on the ascending aorta and aortic root(3.7%). The 1- and 6-year actuarial freedom from reoperation was 100% and 83.3$\pm$15.2%, respectively. One patient with Behcet's disease are waiting for reoperation due to false aneurysm, which developed after aortic root replacement with homograft. There were no thromboembolisms or anticoagulant related complications. Conclusions: This study suggests that reoperations on the ascending aorta and aortic root can be performed with acceptable early mortality and morbidity, and adequate surgical strategies according to the pathologi conditions are critical to the prevention of the reoperation.

With the development of anticancer chemotherapy and improved radiographic imaging studies, limb salvage operation became possible in the treatment of malignant and aggressive benign tumors. High grade sarcomas of the shoulder or the upper extremity can be surgically treated with a forequarter amputation, shoulder disarticulation or limb salvage surgery such as Tikhoff-Linberg procedure, segmental resection and replacement with endoprosthesis, segmental resection and replantation, or segmental resection and free vascularized bone graft. Among them the limb salvage surgery showed not only preservation of the remained upper extremity but also the excellent functional results. When comparing amputation and limb salvage operation while performing anticancer chemotherapy in both cases, 5 year survival rate, local recurrence, and distant metastasis did not show much difference. We studied 13 cases of limb salvage for the malignant and aggressive benign bone tumor of the upper extremity from March 1986 to December 1993 at Severance hospital. The summarized results were as follows. 1. There were 21 cases of malignant bone tumors and 5 cases of benign aggressive ones. 2. Of the 26 cases of malignant and benign aggressive bone tumors, limb salvage procedures such as Tikhoff-Linberg operation(8 cases), endoprosthetic replacement(2 cases), segmental resection and replantation(2 cases), and segmental resection and free vascularized fibular graft(l case) were done in 13 cases. 3. In 13 patient on whom the limb salvage procedure was performed, there were 3 osteosarcomas, 4 chondrosarcomas, 3 giant cell tumors, 1 Ewing's sarcoma, 1 leiomyosarcoma and 1 chondroblastoma. 4. In 13 patients, there was no local recurrence nor distant metastasis except one who had a segmental resection of the entire humerus part including glenoid and then postoperative anticancer chemotherapy for the treatment of the Ewing's sarcoma of the entire shaft of the humerus with pathological fracture. Local recurrence occurred 2 years and 6 months postoperatively in this Ewing's sarcoma patient, so forequarter amputation was performed and the irradiation and the anticancer chemontherapy were performed, but multiple bony metastasis developed and died of the disease 22 months after local recurrence. 5. The patients were followed-up for I year to 7 years and 5 months(average 4 years 5 months). 6. In 8 cases in which Tikhoff-Linberg procedure was performed, the function of the hand was almost normal. 7. Segmental resection and endoprosthetic replacement was performed in 2 cases, and the function of the remained upper extremity was good with no evidence of aseptic loosening or nerve palsy. 8. In 1 case of segmental resection and free vascularized fibular graft for the patient of the chon drosarcoma in the humerus, the function of the shoulder, elbow and hand was nearly normal. 9. In I case of leiomyosarcoma which involved both forearm muscles and bone near wrist joint, segmental resection and replantation was performed, and the patient has useful hand function.
From 1979 to 1984, 39 local allograft irradiations were given to 29 patients: 10 irradiations were administered for prevention and 29 for reversal of acute rejection of transplanted kidney. Three doses of 150 cGy every other day were combined with high-dose of methylprednisolone pulse (1 gm/day) for 3 days. For prevention of acute rejection, local irradiation was delivered on the days 1, 3, and 5 after the transplantation, and for reversal, irradiation started after the diagnosis of acute rejection. Eight out of 10 patients irradiated for prevention had acute allograft rejection, and, what is more, there was no surviving graft at 15 months after transplantation. Reversal of acute rejection was achieved in $71\%$. When the pre-irradiation level of serum creatinine was below $5.5mg\%$, the reversal rate was $93\%$, but above $5.5mg\%$ the reversal rate was only $17\%$ (p<0.01). Reirradiation after failure was not successful. Among 15 reversed patients, $7(47\%)$ had subsequent rejection (s). The functional graft survivals at 6 month, 1, 2, and 3 year were $70\%,\;65\%,\; 54\%,\;and\;54\%$, respectively. Therapeutic irradiation resulted in better graft survival when serum creatinine was below $5.5mg\%$ (p<0.001) or when irradiation started within 15 days after the diagnosis of acute rejection (p<0.001).

A total of 20 patients (male: female=10:10, adult:children=8:12) with brainstem tumors had been received radiation therapy in the Department of Radiation Oncology, Yonsei Cancer Center, Yonsei University College of Medicine between 1980 and 1990. Thirteen of 20 patients were treated with conventional radiation therapy (before 1989, 180~200 cGy per fraction, 5 days a week, total dose 4680~5400 cGy), and seven patients were treated with hyperfractionated radiation therapy (in 1990, 100 cGy per fraction, twice daily 10 fractions a week, total dose 7200 cGy). Median follow up Periods for conventional radiation therapy group and hyperfractionated radiation therapy group were 36 months and 10 months, respectively. Four of 20 Patients had histopathologic diagnosis prior to treatment; 3 cases were low grade astrocytoma and 1 case was high grade astrocytoma. Overall 2-year actuarial survival rate was 30%. The prognosis of patients with a longer duration of symptom and sign was better (60%, vs 12%), and the adult (52%) was better than children (14%). There was no significant difference between the focal (29%) and diffuse (26%) type. The initial clinical response was better in the hyperfractionated radiation therapy group. Because of the relatively small number of Patients and short follow up Period in hyperfractionated radiation therapy group, there was no comparison between two group.

Purpose: We analyzed the oncological outcome and prognostic factor of the chondrosarcoma arising from benign bone tumor due to malignant transformation. Materials and Methods: From April 1986 to April 2009, 18 cases were considered eligible. We analyzed retrospectively the patient's characteristics and prognostic factors that affect to the local recurrence and distant metastasis. Results: As classified by primary benign bone tumor, 4 cases were solitary osteochondroma, 11 cases were multiple osteochondromatosis and 3 cases were multiple enchondromatosis. The mean follow-up period was 85 months. The 5-year disease free survival rate of 18 patients was 85.9%. Their overall MSTS score was 25.2 (84%). There were local recurrence in 3 cases and no distant metastasis. We found that tumor location and surgical margin affected to the prognosis significantly. Conclusion: In secondary chondrosarcoma patients, the prognosis was good relatively and tumor location and surgical margin are important prognosis factor.
Bronchoplastlc procedures including sleeve lobectomy were initially introduced for patients whose pulmonary function was insufficient to tolerate pneumonectomy In more recent years, sleeve lobectomy has evolved as an alternative to pneumonectomy in carefully selected cases of bronchogenic carcinoma, especially for centrally located lesions. Between 1992 and 1995, bronchoplastic procedures for bronchogenic carcinoma were performed in 15 patients and the majority of operative procedures were sleeve lobectomy (W: 12). All procedures were considered as complete and potentially curative. Mean age was 62.3 years (range 46 to 70 years) and there were 12 males and 3 females. Of 15 patiients, 7 underwent right upper sleeve, 2 underwent right lower sleeve, 5 underwent left upper sleeve, and 1 underwent right sleeve pneumonectomy. Postoperative staging was , stage I in 3, stage ll in 8, stage llla in 3 and stage lII in 1. The postoperative complications included anastomosis site obstruction due to granulation tissue in 1, local recurrence in 3, and wound infection in 1 There were 1 operative death due to sepsis and 2 late deaths. The three-year survival rate was 80%. The significant correlation was observed (r=0.11) between the predicted FEVI (1.851 L) and measured FEVI (1 762L). In conclusion, bronchoplastic procedure will have better prognosis than pneumonectomy in selected lung cancer patients because of preserving good function in remnant lung.

One hundred sixty one patients with the carcinoma of uterine cervix received curative radiotherapy at the Department of Therapeutic Radiology, Seoul National University Hospital between December, 1979 and December, 1982. According to FIGO classification; stage $I_a 1(0.6\%)\;1_b\;8(5.0\%),\;II_a\;31(19.3\%),\;II_b\;66(41.0\%),\;III_a\;3(1.8\;%),\;III_b\;46(28.6\%)\;and\;IV_a\;6(3.7\;%)$. The proportion of early stage cancer is too small because most of them treated by surgery. External beam whole pelvic irradiation was done first with 10MV x-ray or Co-60 gamma ray upto 4,000 or 5,000 rad for early and advanced cases, followed by one or two courses of intracavitary radiation using Fletcher-Suit Applicator loading c Cs-137. Supplementary external radiation to pelvic side wall to bring dose to 6,000 or 6,500 rads, if there is parametrial involvement or positive pelvic lymph node. Of the 161 Patients, 49 Patients were lost to follow-up but only 22 patients were lost in disease free state. And so, 86.3 percent of the patients were followed to time of recurrence or to date. The results are as follows ; 1. Locoregional control rates according to stage is: stage I $100\%,\;II_a\;90.3\;%,\;II_b\;75.8\%,\;III_a\;66.7\%,\;III_b\;58.7\%\;and\;IV_a\;16.7\%$, respectively. 2. Persistent or recurrent disease were localized in pelvic cavity in 32 of 50 patients and 6 had distant metastasis only. 3. Rectal bleeding was the most common complication and appeared mostly between 6 and 24 months after radiotherapy. Most of them had transient minor bleeding and only 2 patients needed transfusion and 1 patient needed colostomy due to rectovaginal fistula. 4. The 3 year disease free survival rate is: stage I $100\%,\;II_a\;78.0\%,\;II_b\;60.6\%,\;III_a\;66.7\;III_b\;46.3\%\;and\;IN_a\;16.7\%$, respectively.
Background: Gall bladder cancer (GBC) is highly fatal disease with poor prognosis, with a 5 year survival rate of <10%. It is relatively rare cancer worldwide; however it is the sixth cancer and second most common gastrointestinal tract cancer in Nepalese women. The study focused on associations of certain demographic, lifestyle, dietary, and reproductive factors with gall bladder cancer. Materials and Methods: We conducted a hospital-based matched case control study on newly diagnosed cases of primary GBC at BP Koirala Institute of Health Sciences and BP Koirala Memorial Cancer Hospital. Controls were healthy non-GBC relatives of cancer patients, matched for age, sex and marital status (in case of females) with cases at a ratio of 1:2. Data were collected between April 2012-April 2013 by semi structured interview from both cases and controls. Analyses were carried out with SPSS. Conditional logistic regression was used to find odds ratios and 95% confidence intervals for bivariate and multivariate analysis. Results: A total of 50 cases and 100 controls were enrolled in this study. On bivariate analysis, factors found to be significantly associated with gallbladder cancer were illiteracy (OR=3.29, CI=1.06-10.2), history of gallstone disease (OR=27.6, CI=6.57, 115.6), current smoker (OR=2.42, CI=1.005-5.86), early menarche <13 years (OR=2.64, CI=1.09-6.44), high parity more than 3 (OR=3.12, CI=1.25,7.72), and use of mustard oil (OR=3.63, CI=1.40, 9.40). A significant protective effect was seen with high consumption of fruits at least once a week (OR=0.101, CI=0.03-0.35). On multivariate analysis, history of gallstone disease, early menarche, current smoker and high consumption of fruits persisted as significant factors. Conclusions: History of gallstone disease, cigarette smoking and early menarche were associated with increased risk of gallbladder cancer while high consumption of fruits was found to have a protective effect.
The laryngeal carcinoma is the most frequent malignant tumor in the E.N.T. field. In the surgical treatment of laryngeal carcinoma, in 1873, Billroth performed the first total laryngectomy, and in 1863, H. B. Sands performed the first partial laryngectomy. Recently general advances (antibiotic therapy, blood trasfusion, and safer anesthesia) result in the improvement of postoperative prognosis. Because the laryngeal lymphatic system has the characteristic compartmentation, this serves the anatomic basis for performing the partial laryngectomy. Although the indications of partial laryngectomy are different from that of total laryngectomy, the partial laryngectomy has the advantage of not only removal of all malignant disease, but also maximum preservation of respiratory, phonatory, and sphincteric function of the larynx. In the latest, surgical treatment decreased the frequency of recurrence, and also increased the 5 year survival rate with combination of the chemotherapy and radiation therapy. The authors have experienced 8 cases of partial laryngectomy for laryngeal carcinoma at the department of otolaryngology, Korea University Hospital from 1980 to 1982. Among the total 8 cases, 2 cases were involved only in the epiglottis, 2 cases in the anterior 1/3 of both vocal cords with ant. comissure, 2 cases in the middle 1/3 of Lt. vocal cord, 1 case in the anterior 1/3 of Rt. vocal cord with ant. comissure, and another 1 case in the Rt. ventrical. So authors report these cases with review of the literature.
Background: The origin site of carcinoma invading esophagogastric junction is variable. It may arise from squamous cell carcinoma of low esophagus, adenocarcinoma arising from Barrett's esophagus, adenocarcinoma of gastric cardia, or extension from proximal stomach cancer. In Korea, the majority of adenocarcinoma invading esophago-gastric junction seems to arise from proximal gastric carcinoma. Material and Method: We reviewed the data of surgically-resected gastric adenocarcinoma involving esophagogastric junction in KCCH between 1988 and 1999. Result: There were 212 cases. Male to female ratio was 156 to 56. Age distribution was between 22 and 78. Variable surgical approaches including median laparotomy, laparotomy with left or right thoracotomy, left thoracotomy, and thoracoabdominal approach were used. Postoperative pathologic stages were : Stage IA-7, IB-11, Ⅱ-25, ⅢA-73, ⅢB-34, and Ⅳ-57. Curative resection was performed in 199 patients, and total gastrectomy was performed in 200 patients. There were 77.4%(164 cases) with esophageal involvement, 74.1%(157 cases) with tumor involvement in the abdominal LN, and 8%(17 cases) with mediastinal LN metastasis. Operative mortality was 3.3%, and over-all 5 year survival rate was 35%. Conclusion: There are various surgical approaches and many things to consider for surgical resection, thoracic and abdominal approach may need for obtain proper resection margin and adequate lymph node dissection in stomach cancer invading esophagogastric junction.
