  • This is a retrospective analysis of 135 patients with invasive carcinoma of the uterine cervix treated with curative radiotherapy from March 1983 through October 1989 at the Department of Therapeutic Radiology, Kang-Nam 51. Mary's Hospital. Among them, 78 patients received radiotherapy alone and 42 patients treated with neoadjuvant chemotherapy followed by radiotherapy and 15 patients were lost to follow up. All patients had follow up from 2 to 106 months (median; 62 months). Age of the patients ranged from 32 to 79 years at presentation (median; 59 years). According to FIGO classification, there were 20 ($16.7{\%}$) in stage IB, 19 ($15.8{\%}$) in stage IIA,49 ($40.8{\%}$) in stage IIB, 5 ($4.2{\%}$) in stage IIIA, 13 ($10.8{\%}$,) in stage IIIB,14 ($11.7{\%}$) in stage IVA. The pathological classification showed 96 ($80.0{\%}$) squamous cell carcinomas, 5 ($4.2{\%}$) adenocarcinomas and 19 ($15.8{\%}$) proven by cytology. The overall 5-year survival rates was $50.8{\%}$, and the 5-year survival rates by stage IB, IIA, IIB, IIIA, IIIB, IVA was $47.7{\%},\;70.2{\%},\;64.1{\%},\;40.0{\%},\;23.1{\%},\;14.3{\%}$, respectively. The 5-year survival rates was noted $51.2{\%}$ of radiotherapy alone and $50.4{\%}$of neoadjuvant chemotherapy followed by radiotherapy. The overall failure rate was $18.3{\%}$(22/120) including $11.7{\%}$ (14/120) locoregional failure, $5.8{\%}$ (7/120) distant metastasis and $0.8{\%}$(1/120) locoregional failure with distant metastasis. Treatment failure rates by the stages were $15{\%}$ (3/20) in stage IB. $10.5{\%}$ (2/19) in stage IIA, $10.2{\%}$, (5/49) in stage IIB, $20{\%}$ (1/5) in stage IIIA, $61.5{\%}$(8/13) in stage IIB, and $28.6{\%}$ (4/14) in stage IVA. The overall complication rate was $34.2{\%}$(41/120) including wet desquamation $7.5{\%}$, (9/120), diarrhea $6.7{\%}(8/120), radiation proctitis $5.8{\%}$(7/120) in decreasing order. A multivariate analysis of factors influencing the survival showed patient age (p < 0.0291), FIGO stage (p<0.0001), Karnofsky performance status (p<0.0043), initial hemoglobin level (p<0.0001), and intracavitary radiation (p<0.0004), but, no significancy in histology (p<0.29) and treatment method (p < 0.87).

  • Eighty five patients of oral cavity cancer, treated with radiation at the Department of Therapeutic Radiology, Korea Cancer Center Hospital, during the period from March 1985 to September 1990 were analyzed retrospectively. Among 85 patients, 37 patients were treated with radiation only and 48 patients were treated with radiation following surgery. And 70 patients received external irradiation only by $^{60}Co$ with or without electron, the others were 7 patients for external irradiation plus interstitial implantation and 8 patients for external irradiation plus oral cone electron therapy. Primary sites were mobile tongue for 40 patients, mouth floor for 17 patients, palate for 12 patients, gingiva including retromolar trigone for 10 patients, buccal mucosa for 5 patients, and lip for 1 patient. According to pathologic classification, squamous cell carcinoma was the most common (77 patients). According to AJC TNM stage, stage I + II were 28 patients and stage III+IV were 57 patients. Acturial overall survival rate at 3 years was $43.9\%,$ 3 year survival rates were $60.9\%$ for stage I + II, and $23.1\%$ for stage III+IV, respectively. As a prognostic factor, primary T stage was a significant factor (p<0.01). The others, age, location, lymph node metastasis, surgery, radiation dose, and cell differentiation were not statistically significant. Among those factors, radiation plus surgery was more effective than radiation only in T3+T4 or in any N stage although it was not statistically sufficient (p<0.1). From those results, it was conclusive that definitive radiotherapy was more effective than surgery especially In the view of pertainig of anatomical integrity and function in early stage, and radiation plus surgery was considered to be better therapeutic tool in advanced stage.

  • Purpose : First of all, this study was performed to assess the result of curative radiotherapy and to evaluate different possible prognostic factors for squamous cell carcinoma of the supraglottic larynx treated at the Pusan National University Hospital. The second goal of this study was by comparing our data with those of other study groups, to determine the better treatment policy of supraglottic cancer in future. Methods and Material : Thirty-two patients with squamous cell carcinoma of the supraglottic larynx were treated with radiotherapy at Pusan National University Hospital, from August 1985 to December 1996. Minimum follow-up period was 29 months, Twenty-seven patients (84.4$\%$) were followed up over 5 years. Radiotherapy was delivered with 6 MV photons to the primary laryngeal tumor and regional iymphatics with shrinking field technique. Ail patients received radiotherapy under conventional fractionated schedule (once a day). Median total tumor dose was 70.2 Gy (range, 55.8 to 75.6 Gy) on primary or gross tumor lesion. Thirteen patients had Induction chemotherapy with cisplatln and 5-fluorouracil (1-3 cycles). Patient distribution, according to the different stages, were as follows: stage I, 5/32 (15.6$\%$): stage II, 10/32 (31.3$\%$); stage III, 8/32 (25$\%$): stage IV, 9/32 (28.1$\%$). Results :The 5-year overall survival rate of the whole series (32 patients) was 51.7$\%$. The overall survival rate at 5-years was 80$\%$ in stage I, 66.7$\%$ in stage II, 42.9$\%$ in stage III, 25$\%$ in stage IV (p=0.0958). The S-year local control rates after radiotherapy were as fellows: stage I, 100$\%$; stage II, 60$\%$ stage III, 62.5$\%$; stage IV, 44.4$\%$ (p=0.233). Overall vocal preservation rates was 65.6$\%$, 100% In stage I, 70% in stage II, 62.5$\%$ In stage III, 44.4$\%$ in stage IV (p=0.210). There was no statistical significance in survival and local control rate between neoadjuvant chemotherapy followed by radiotherapy group and radiotherapy alone group. Severe laryngeal edema was found in 2 cases after radiotllerapy, emergent tracheostomy was done. Four patients were died from distant metastsis, . three in lung, one in brain. Double primary tumor was found in 2 cases, one in lung (metachronous), another in thyroid (synchronous). Ulcerative lesions were revealed as unfavorable prognostic factor ( p=0.0215), and radiation dose (more or less than 70.2 Gy) was an important factor on survival (p=0.002). Conclusion : The role of radiotherapy treatment of supraglottic carcinoma is to important factor on survival and to preserve the laryngeal function. Based on our data and other studies, early and moderately advanced supragiottic carcinomas could be successfully treated with either consewative surgery or radiotherapy alone. Both modalities showed similar results in survival and vocal preservation. For the advanced cases, radiotherapy alone is Inadequate for curative aim and surgery combined with radiotherapy should be done in operable patients. When patients refuse operation or want to preserve vocal function, or for the patients with inoperable medical conditions, combined chemoradiotherapy (concurrent) or altered fractionated radiotherapy with or without radiosensitizer should be taken into consideration in future.

  • 후두암의 치료는 병변의 위치, 크기 등에 따라 치료방법이 다양하고 그 예후 또한 상이하다. 일반적으로 초기 후두암에서는 수술이나 방사선 요법이 비슷한 치료결과를 보이고, 진행된 후두암에서는 수술적 치료가 더 좋은 예후를 나타내는 것으로 알려져 있으나 발성장애를 초래하는 경우가 대부분이다. 저자들은 1986년부터 1990년까지 5년간 강남성모병원에서 후두암치료를 받았던 환자 81명을 대상으로 치료방법에 따른 음성보존 성적을 분석하였다. 1. T1 성대암 환자 18명중 16명 (88.9%)에서 방사선치료 또는 수술로써 음성을 보존할 수 있었다. 2. T2 후두암 환자 11명중 6명은 수술후 음성보존이 가능하였다. 3. 진행암환자 (T3, T4) 50명중 33명에 대해 수술을 시행하였고 이중 16명(48.5%)은 후두부분 또는 근전적출술 및 기관-식도 누공술에 의해 음성기능을 보존할 수 있었다. 4. 진행암환자에서 유도화학요법과 방사선치료의 병용요법만을 받은 17명 모두 6개월 이내에 재발하였고, 수술 혹은 수술과 방사선 치료를 병용한 33명중 27명이 최소한 6개월 이상 평균 2년 이상의 무병상태였다. 5. 후두부분 또는 근전적출술은 총 81명중 28명에서 시행되었고 그중 5명 (17.9%)에서 재발하였다.

  • Objectives: To evaluate the efficacy and safety of induction chemotherapy with docetaxel and cisplatin in locally advanced head and neck cancer. Materials and Methods: Between June 1998 and December 2004, 30 patients were enrolled and among them, 20 patients were evaluable. Patients were treated with docetaxel $75mg/m^2$ and cisplatin $60mg/m^2$ on day 1 every 21 days. Results: The median age was 71(range 54-80) years old. All 20 patients were male. Nineteen patients had pathologically squamous cell carcinoma and 1 had undifferentiated carcinoma. Fourteen of 20 patients(70%) demonstrated an objective response with two(10%) achieving a complete clinical response and eleven(60%) a partial response. The median response duration was 5.3(1.6-32.1) months and the median time to progression was 5.6(1.4-33.8) months. The median overall survival of all patients was 14(range 2.2-34) months. The median overall survival of responders was 17.5(range 5-34) months and that of non-responders was 3.2(range 2.2-23) months, but it was not statistically significant(p=0.106). During a total of 92 cycles, granulocytopenia worse than CTC(Common toxicity criteria) grade 2 occurred in 6%, thrombocytopenia in 2%, and anemia in 3%, respectively. Non-hematologic toxicities were minor and easily controlled. Conclusion: The induction chemotherapy of docetaxel and cisplatin has moderate efficacy with acceptable toxicities in patients with locally advanced head and neck cancer.

  • 목 적 : 씨클로포스파미드(Cyclophosphamide, CP)는 많은 종양 질환에서 단독 혹은 다른 화학요법과 함께 사용되는 항암제이다. CP의 독성과 부작용으로 출혈성 방광염이 많은 문제를 일으키고 있다. CP로 유도된 방광염 모델은 하부요로의 통증질환을 이해하기 위한 내장성 통증의 주요한 모델로 사용되고 있다. 본 연구는 암컷 백서에서 CP로 유도된 방광의 과활동성에 대한 침의 효과를 관찰하기 위해 요류역학검사를 수행하였다. 방 법 : CP (200 mg/kg) 투여 18시간 후에, 지속적 생리식염수 관류 (분당 0.04 ml) 로 방광내압 측정을 통해 방광기능을 평가하였다. 관류 2시간 이후부터, 위중/곤륜 100 Hz, 위중/곤륜 2 Hz, 족삼리/삼음교 100 Hz, 족삼리/삼음교 2Hz 전침 자극을 하여 자침 전후의 방광수축간격(intercontraction interval, ICI)을 비교하였다. 결 과 : 방광내압 측정하는 동안, 방광수축간격은 CP로 유도된 방광염 모델에서 정상군에서 보다 유의하게 짧았다. CP로 유도된 방광염 모델에서, 위중/곤륜 100Hz 전침 자극은 자침 전보다 통계적으로 유의하게 $40.6\;{\pm}\;10.9\;%$ 증가시켰고, 2Hz 전침 자극은 자침 전보다 현저하게 $22.1\;{\pm}\;13.7\;%$ 증가시켰다. 반면에, 족삼리/삼음교 전침 자극은 100Hz, 강 2Hz 전침 자극 각각 $13.7\;{\pm}\;8.1\;%,\;8.7\;{\pm}\;4.5\;%$ 약간 증가시켰다. 결 론 : 족태양방광경의 경혈에 100Hz 전칩 자극을 하여 CP로 유도된 방광의 과활동성을 억제하였다. 이러한 결과는 침 자극으로 CP로 유도된 혹은 다른 종류의 방광염을 치료하는데 효과적일 것임을 시사한다. 또한, 특정 경락의 경혈과 해당 장부의 질환의 치료에 연관성을 보여준다.

  • of $PLC-\gamma$ 1 activity. Results : In the immunohistochemistry, the expression of $PLC-\beta$ was negative for all grnups. The expression of $PLC-\gamma$ 1 was highest in the group III followed by group II in the proliferative zone of mucosa. The expression of PKC-01 was strong1y positive in group I followed by group II in the damaged surface epithelium. The above findings were also confirmed in the immunoblotting study. In the irnrnunoblotting study, the expressions of $PLC-\beta,\;PLC-\gamma\;1,\;and\;PLC-\delta$ were the same as the results of immunohistochemistry The expression of ras oncoprotein was weakly Positive in groups II, III and IV. The of EGFR was the highest in the group II, III, followed by group W and the expression of PKC was weakly positive in the group II and III. Conclusion : $PLC-\gamma$ 1 mediated signal transduction including ras oncoprotein, EGFR, and PKC play a significant role irL mucosal regeneration after irradiation. $PLC-\delta$ 1 mediated signal transduction might have an important role in mucosal damage after irradiation. Further studies will be necessary to confirm the signal transduction mediating the $PLC-\delta$ 1.
