PURPOSE: We performed the retrospective analysis to find the outcome of external beam radiotherapy alone in advanced esophageal cancer patients. METHODS AND MATERIALS: One hundred and six patients treated with external beam radiotherapy alone between July 1990 and December 1996 were analyzed retrospectively. We limited the site of the lesions to the thoracic esophagus and cell type to the squamous cell carcinoma. Follow-up was completed in 100 patients (9 4%) and ranged from 1 month to 92 months (median; 6 months). RESULTS: The median age was 62 years old and male to female ratio was 104:2. Fifty-three percent was the middle thorax lesion and curative radiotherapy was performed in 83%. Mean tumor dose delivered with curative aim was 58.6 Gy (55-70.8 Gy) and median duration o f the radiation therapy was 53 days. The median survival of all patients was 6 months and 1-year and 2-year overall survival rte was 27% and 12%, respectively. Improvement of dysphagia was obtained in most patients except fo 7 patients who underwent feeding gastrostomy. The complete response rate immediately after radiation therapy was 32% (34/106). The median survival and 2-year survival rate of the complete responder was 14 months and 30% respectively, while those of the nonresponder was 4 months and 0% respectively (p=0.000). The median survival and 2-year survival rate of the patients who could tolerate regular diet was 9 rnonths and 16% while those of the patients who could not tolerate regular diet was 3 months and 0%, respectively (p=0.004). The survival difference between the patients with 5 cm or less turnor length and those with more than 5 cm tumor length was rnarginally statistically significant (p=0.06). However, the survival difference according to the periesophageal invasion or mediastinal lymphadenopathy in the chest CT imaging study was not statistically significant in this study. In a multivariate analysis, the statistically significant covariates to the survival were complete response to radiotherapy, tumor length, and initial degree of dysphagia in a decreasing order. The complication was observed in 10 patients (9%). CONCLUSION: The survival outcome for advanced esophageal cancer patients treated by external be am radiotherapy alone was very poor, In the treatment of these patients, the brachytherapy and chemotherapy should be added to improve the treatment outcome.

Behcets disease is a chronic systemic disease of unknown etiology, which is characterized by the recurrent orogenital ulcers, eye involvement and skin manifestations. In addition to the major symptoms, it includes arthritis, vasculitis, neurologic manifestations and gastrointestinal lesions. We report a case of Behcets disease associated with intestinal ulcers. The patient, a 45-year-old female, who had been treated under the diagnosis of Behcets disease for 4 years, presented with swallowing difficulty, vaginal discharge and persistent right lower abdominal pain. Colonoscopic examination showed multiple ulcers on the ileocecal region which is reported as the most common site of gastrointestinal Behcets disease. Gastrointestinal evaluation can be useful in diagnosis of Behcets disease, especially in a patient with gastrointestinal symptoms.

The finger flexor injuries are very difficult to treat satisfactorily. It is usually said that the earlier the treatment performed, the better result obtained. But the delicasy of the hand anatomy and its function as well as the absence of the hand surgeon in the first aid care make the problem more complex. Even if we made the primary treatment to the flexor tendon injuries, some disabilities are often remained. We have treated fifty eight cases of old flexor tendon injuries in forty eight patients, the results can be summarized as follows. 1. The cause of the tendon damage is due to the laceration injury in the majorities of the cases. T,he tendon injuries are especially common between the late second and the early third decade. 2. In the injury of the Zone II with pulley distortion, the pulley reconstruction using palmaris longus or fascia from other sites will prevent bowstring and help the tendon function. 3. The Zone II can be subdivided into two subspecific areas. The proximal area is from the distal palmar crease to the midoprtion of porximal phalanx and the distal one is from the midportion of the proximal phalanx to the insertion of the sublimis tendon. In the proximal area one can repair the injured tendon directly after removal of the A1 and about proximal half of the A2 pulley without any subsequent bowstring if the tendon and its tunnel is relatively well preserved. Thus one can convert this proximal portion of Zone II to Zone III. So the proximal area of the Zone II should be differentiated from the remaining distal part of the Zone II. 4. At six months after the operation the result of the operation was analyzed by the percentage of the recovery, which was calculated by the postoperative active range of the interphalangeal joints divided by one hundred seventy five degrees that means the available total range of motion of normal interphalangeal joints. Excluding the cases with the tenodesis or arthrodesis, the total result revealed good or excellent in about ninty percentages with this method. 5. There were two fingers that showed a postoperative lumbrical plus state in Zone II, which were recovered spontaneously within three to four months postoperatively. So it is considered that the relative shortening of the lumbrical muscles can be treated and overcome conservatively by the active use of the fingers, and there is no need to perform an lumbrical tenotomy to correct this kind of muscle imbalance.

The use of interlocking intramedullary nail is accepted one of treatment choices in the comminuted fractures of humeral shaft. The insertion of distal interlocking screws remains technically problematic. The use of intrageon's hands during the procedure. In order to reduce technical difficulty and radiation exposure, it is necessary to compare the rigidity of intramedullary nail according to the number of distal interlocking screws. The purpose of study is to compare the stability of interlocking intramedullary nail according to the number of distal screws by means of torsional compliance measurements in the simulated humeral shaft fractures. Simulated fractures were made in 20 humora from 10 cadavera at the mid-junction of humeral shaft. All humora were fixated with titaium humeral nail system. Interlocking screws were placed at proximal and distal screw holes by standard procedure. Group I consisted of 10 humora fixated with one distal interlocking screw and group II consisted of 10 humora fixated with two distal intterlocking screws. Torsional compliance was measured with single-end of 10 humora fixated with two distal interlocking screws. Torsional compliance was measured with single-end double arm torquing machine. The torsional compliance analog was 0.0294+/-0.0033 mm/N mm for one screw and 0.0241+/-0.0045 mm/N mm for two distal screws. The torsional compliance analog between two groups was found to be statistically insignificant(p=0.23). In conclusion, One distal interlocking screw was not inferior to two interlocking screws in terms of biomechanical characteristics, especially torsional compliance analog.

Ninety patients of esophageal cancer treated with radiation since November 1985 to June 1990 at the Deprtment of Therapeutic Radiology, Chonnam University Hospital, were analysed retrospectively regarding survival. Seventy five patients (94.9%) revealed squamous cell carcinoma in its histologic type, and most ofpatients were in advanced stage with 25 patients (27.8%) of T2 and 64 patients (71.1%) of T3 Minimum follow up period was 12 months and median was 5 months. Overall actuarial 2 year survival rate was 11.6%. Two year survival rates according to the parameters such as treatment aim, T stage, site, length, radiation dose and response were compared and resulted that survival by tumor length only had statistically significant impact on survival of esophageal carcinoma.

OBJECTIVE: The purpose of this article is to estimate the anti-cancer effects of the major components of the green tea (polyphenols, catechin and EGCG) and the mechanism of EGCG on different cervical cancer cell lines. METHODS: Six cervical cancer cell lines (HeLa, HeLaS3, Caski, SiHa, HT3 and C33A) were treated with 20 microgram/ml green tea polyphenols (GTPs), 50 micrometer catechin and various concentrations of (-)-epigallo- catechin-3-gallate (EGCG). The viabilities were determined by trypan blue exclusion assay, neutral red assay and 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide assay. DNA fragmentation and nuclear condensation were used to see whether EGCG-induced anti-proliferation effect was due to apoptosis. RESULTS: Both GTPs, catechin and EGCG had growth inhibition effects on cervical cancer cell lines, but EGCG appeared to be the most effective. What's more, the sensitivity of each cell lines to EGCG was different. HT3 cells (HPV negative, mutant type p53) were most sensitive to EGCG (estimate IC50: 10 micrometer). Caski (HPV-16 positive, wild type p53) and HeLaS3 cells (HPV-18 positive, wild type p53) were less sensitive (estimate IC50: 35 and 70 micrometer respectively). EGCG-induced apoptosis can be seen in all the cell lines and it happened as early as 8 hours after EGCG treatment. CONCLUSION: Green tea or EGCG alone will be beneficial to the cervical cancer patients.

We present one case report of anterior urethral diverticulum in a male with giant calculi. The patient was a 56-year-old male with the complaints of base-ball sized palpable scrotal mass and post-void dribbling for 15-16 years. The diverticulum was filled with multiple whitish-yellow stones. The largest one was 8X7X6cm in size.

PURPOSE: Before we report the results of curative radiotherapy in cervix cancer patients, we review the significance and safety of our dose specification methods in the brachytherapy system to have the insight of the potential predictive value of doses at specified points. MATERIALS AND METHODS: We analyze the 45 cases of cervix cancer patients treated with intracavitary brachytherapy. In the lateral simulation film we draw the isodose curve and observe the absorbed dose rate of point A, the reference point of bladder(SBD) and rectum(SRD). In the sagittal view of pelvic MRI film we demarcate the tumor volume(TV) and determine whether the prescription dose curve of point A covers the tumor volume adequately by drawing the isodose curve as correctly as possible. Also we estimate the maximum point dose of bladder(MBD) and rectum(MRD) and calculate the inclusion area where the absorbed dose rate is higher than that of point A in the bladder(HBV) and rectum(HRV), respectively. RESULTS: Of forty-five cases, the isodose curve of point A seems to cover tumor volume optimally in only 24(53%). The optimal tumor coverage seems to be associated not with the stage of the disease but with the tumor volume. There is no statistically significant association between SBD/SRD and MBD/MRD, respectively. SRD has statistically marginally significant association with HRV, while TV has statistically significant association with HBV and HRV. CONCLUSION: Our current treatment calculation methods seem to have the defect in the aspects of the nonoptimal coverage of the bulky tumor and the inappropriate estimation of bladder dose. We therefore need to modify the applicator geometry to optimize the dose distribution at the position of lower tandem source. Also it appears that the position of the bladder in relation to the applicators needs to be defined individually to define "hot spots".

Purpose: Significant improvements have been made in the surgical treatment of rectal cancer with a higher sphinctersaving rate without compromising oncologic results. There have been studies about the quality of life of rectal cancer patients after surgery. However, no study has reported the long-term annual incidence of depression after rectal cancer surgery according to stoma status. The objective of this study was to determine the annual incidence of depression after rectal cancer surgery and the factors affecting it, especially the prevalence of depression according to the presence or duration of a stoma. Methods: Using the Korea National Health Insurance Service database, patients who underwent radical surgery for rectal cancer from 2002 to 2019 were searched. We analyzed the incidence and risk factors of depression in patients who underwent radical surgery for rectal cancer according to stoma status. Results: Annual incidence of depression in rectal cancer patients was decreasing annually for 15 years after surgery. There was no statistically significant difference in the incidence of depression according to the stoma status. However, the diagnosis of depression within 1 year after surgery was statistically significantly increased in the permanent stoma group. Conclusion There was no difference in the overall incidence of depressive disorders among patients with rectal cancer based on their stoma status. However, a permanent stoma seems to increase the incidence in the first year after surgery. Education and intensive assessments of depressive disorders in patients with permanent stoma within 1 year after surgery are needed, particularly for female patients who are under 50 years old.

PURPOSE: A retrospective analysis was performed to investigate the proper management of maxillary sinus carcinoma. MATERIALS AND METHODS: Authors analysed 33 patients of squamous cell carcinoma of maxillary sinus treated at Chonnam University Hospital from January 1986 to December 1992. There were 24 men and 9 women with median age of 55 years. According to AJCC TNM system of 1988, a patient of T2, 10 patients of T3 and 22 patients of T4 were available, respectively. Cervical lymph node metastases was observed in 5 patients(N1;4/33, N2b;1/33). Patients were classified as 3 groups according to management method. The first group, named as "FAR" (16 patients), was consisted of preoperative intra-arterial chemotherapy with5-fluorouracil(5-FU;mean of total dosage;3078mg) through the superficial temporal artery with concurrent radiation(mean dose delivered;3433cGy, daily 180-200cGy) and vitamin A(50,000 IU daily), and followed by total maxillectomy and postoperative radiation therapy(mean dose;2351cGy). The second group, named as "SR"(7 patients), was consisted of total maxillectomy followed by postoperative radiation therapy(mean dose 5920 cGy). Her third group, named as "R"(6 patients), was treated with radiation alone(mean dose;7164cGy). Kaplan-Meier product limit method was used for survival analysis and Mantel-Cox test was performed for significance of survival difference between two groups. RESULTS: Local recurrence free survival rate in the end of 2 year was 100%, 5-% and 0% in FAR, SR and R group, repectively. Disease free survival rate in 2 years was 88.9%, 40% and 50% in Far, SR and R group, respectively. There were statistically significant difference between FAR and SR or FAR and R group in their local recurrence free, disease free and overall survival rates. But diffeence of each survival rate between SR and R group was not significant. CONCLUSION: In this study FAR group revealed better results that SR or R group. In the future prospective randomized study is in need.
