The aim of this study was to investigate the early outcome of Endostar combined with chemoradiotherapy for advanced cervical cancer. Fifty-two cases (FIGO IIb to IVa) were divided randomly into two groups, receiving chemoradiotherapy alone (CRT group) and Endostar combined with chemoradiotherapy (CRT+E group). For the patients in the CRT+E group, Endostar was administered daily with the dosage of 7.5 $mg/m^2$, and cisplatin was administered weekly with the dosage of 20 $mg/m^2$ during the radiation. The regimens lasted for 4 weeks with no difference in chemoradiotherapy between the two groups. The early outcome complete remission rate was 73.1%, partial remission rate was 23.1% and the total response rate was 96.2% in CRT+E group, a significant improvement on the 34.6%, 42.3% and 76.9%, respectively, in the CRT group. One year survive rates were 100% and 84.6% in the CRT+E group and CRT groups, the difference being significant. Endostar combined with chemoradiotherapy can improve the early outcome of the advanced cervical cancer, and adverse effects were not encountered.
Purpose : To see the relationship between the response to chemotherapy and the final outcome of neoadiuvant chemotherapy and radiotherapy in patients with mocanry advanced hypopharyngeal cancer. Methods and Materials :A retrospective analysis was done for thirty-two patients with locally advanced hypopharyngeal cancer treated in the Seoul National University Hospital with neoadiuvant chemotherapy and radiotherapy from August 1979 to July 1997. The patients were treated with Co-60 teletherapy unit or 4MV or 6MV photon beam produced by linear accelerator. Daily fractionation was 1.75 to 2 Gy, delivered five times a week. Total dose ranged from 60.8 Gy to 73.8 Gy. Twenty-nine patients received continuous infusion of cisplatin and 5-FU. Other patients were treated with cisplatin combined with bleomycin or vinblastin. Twenty-four (75$\%$) patients received all three prescribed cycles of chemotherapy delivered three weeks apart. Six patients received two cycles, and two patients received only one cycle. Results :The overall 2-year and 5-year survival rates are 65.6$\%$ and 43.0$\%$, respectively. 5-year local control rate is 34$\%$. Organ preservation for more than five years is achieved in 12 patients (38$\%$). After neoadjuvant chemotherapy, 24 patients achieved more than partial remission (PR): the response rate was 75$\%$ (24/32). Five patients had complete remission (CR), 19 patients PR, and 8 patients no response (NR). Among the 19 patients who had PR to chemotherapy, 8 patients achieved CR after radiotherapy. Among the 8 non-responders to chemotherapy, 2 patients achieved CR, and 6 patients achieved PR after radiotherapy. There was no non-responder after radiotherapy. The overall survival rates were 60$\%$ for CR to chemotherapy group, 35.1$\%$ for PR to chemotherapy group, and 50$\%$ for NR to chemotherapy group, respectively (p=0.93). There were significant difference in five-year overall survival rates between the patients with CR and PR after neoadjuvant chemotherapy and radiotherapy (73.3$\%$ vs. 14.7$\%$, p<0.01). The prognostic factor affecting overall survival was the response to overall treatment (CR vs. PR, p<0.01). Conclusion :In this study, there were only five patients who achieved CR after neoadiuvant chemotherapy. Therefore the difference of overall survival rates between CR and PR to chemotherapy group was not statistically significant. Only the response to chemo-radiotherapy was the most important prognostic factor. There needs to be more effort to improve CR rate of neoadjuvant chemotherapy and consideration for future use of concurrent chemoradiotherapy.

Purpose : The aim of this study was to assess the effectiveness, survival rate and complications of radiation therapy and chemoradiation treatment in hypopharyngeal cancer. Methods and Materials : From January 1984 to December 1999, 56 patients who had hypopharyngeal carcinoma treated with curative radiation therapy were retrospectively studied. Twenty four patients $(42.9\%)$ were treated with radiation therapy alone (Group I) and $32\;(57.1\%)$ treated with a combination of chemotherapy and radiation (Group II). Total radiation dose ranged from 40.5 to 83. 5 Gy (median 67.9 Gy). Radiotherapy was given with conventional technique in 9 patients $(16.4\%)$, with hyperfractionation I ($1.15\~1.2$ Gy/fr., BID) in 26 $(47.2\%)$, hyperfractionation II (1.35 Gy/fr., BID) in 18 $(32.7\%)$, and accelerated fractionation (1.6 Gy/fr., BID) in 2 $(3.6\%)$. In chemotherapy, 5-FU ($1,000\;mg/m^2$ daily for 5 consecutive days) and cisplatin ($100\;mg/m^2$ on day 1) were administered in a cycle of 3 weeks interval, and a total of 1 to 3 cycles (average 2..3 cycles) were given prior to radiation therapy. Follow up duration was $1\~195$ months (median 28 months). Results : Overall 2 and 5 year survival rates were $40.6\%\;and\;27.6\%;\;50.0\%\;and\;30.0\%$ in Group I, and $36.4\%\;and\;26.3\%$ in Group II, respectively. Complete local control rates in Group I and II were $70.0\%\;and\;67.7\%$, respectively. The response to radiotherapy and nodal stage were statistically significant prognostic factors. The complication rate was increased in Group II and was decreased in hyperfractionation. Conclusion : The response to radiotherapy and nodal stage were valid factors to indicate the degree of control over the hypopharyngeal cancer. The induction cisplatin, 5-Fu chemotherapy was not valid in terms of local control rate and survival rate, but did contribute to an increased complication rate. The use of hyperfractionation was valid to reduce the late radiation complications.
연구방법 : 근치적 목적의 동시항암방사선치료를 시행받은 비인강암 환자들을 대상으로하여 치료 효과와 독성에 대한 후향적 분석을 시행하였다. 환자 및 방법 : 1993년 8월부터 1999년 3월까지 원격전이가 없는 50명의 비인강암 환자들이 방사선 치료기간 중 주 1회의 시스플라틴 $20mg/m^2$을 투여받았고, 1999년 4월부터 2000년 4월까지 20명의 환자가 상기 용량의 시스플라틴에 더하여 경구용 UFT300mg을 추가적으로 투여받았다. 총 70명 환자들의 임상기록과 병리 기록지를 검토하였다. 결 과: 연령의 중앙값은 47세 (범위 $18{\sim}76$)였고, 남자와 여자가 각각 53명과 17명 이었으며, 병기 II, III, IVA, IVB가 각각 23명, 14명, 15명, 18명이었다. 치료에 대한 반응율은 92.8%(95% C.I. $42{\sim}143%$)였고(완전반응 57명, 부분반응 8명), 총 34개월의 추적 관찰 기간 동안에 완전반응을 보인 57명 중 21명에서 재발(국소재발 5, 원격전이 11, 복합전이 5)을 하였다. 3년 무진행 생존율은 51.5%였으며 5년 생존율은 60.3%였다. 경구용 UFT의 추가적 사용은 주 1회 시스플라틴 항암치료에 비하여 반응율과 생존율 및 독성에 유의한 영향을 미치지 않았다. 결 론: 주 1회 저용량 시스플라틴$\pm$경구용 UFT를 이용한 동시항암방사선요법은 비인강암 환자의 치료에 있어서 비교적 적은 독성으로 높은 반응율을 나타내었으나, 향후 재발율을 감소시키기 위한 연구가 지속되어야 할 것으로 사료된다.
Objectives: We performed this study to compare the short term results of induction chemotherapy and radiotherapy versus concurrent chemoradiotherapy in patients with locally advanced head and neck cancer. Materials and Methods: From Oct. 1985 to May 1998, 121 patients with locally advanced head and neck cancer were treated with induction chemotherapy and radiotherapy (induction group) or concurrent chemoradiotherapy (concurrent group), and a retrospective analysis was done. Induction chemotherapy was done for 97 patients, and concurrent chemotherapy for 24 patients. Age, sex, performance status, and pathologic types were evenly distributed between two groups. Primary site showed nasopharynx(72.2%), oropharynx(27.8%) in induction group, and nasopharynx(50%), oropharynx(50%) in concurrent group. Chemotherapy regimen was CF(cisplatin and 5-fluorouracil) for 67 patients and CVB (cisplatin, vincristine, bleomycin) for 30 patients in induction group, and CF for all of 24 patients in concurrent group. Proportion of patients treated with more than 2 cycles of planned chemotherapy was 94.8% in induction group and 87.5% in concurrent group. Conventionally fractionated radiotherapy with daily fraction size of 1.8-2.0Gy and 5 fractions/week was done. Total dose was 61-95Gy (median 73.4Gy) for induction group, and 69.4-75.4Gy (median 69.4Gy) for concurrent group. Follow-up time was 4-161 months (median 38 months) for induction group, 7-35 months (median 21.5 months) for concurrent group, respectively. Results: According to treatment modality, overall 2-year survival rates were 68.0% for induction group, 74.3% for concurrent group (p>0.05). two-year disease-free survival rates were 51 % and 74% (p=0.05). Complete response rates were 67.4% for induction group and 83.3% for concurrent group (p=0.09). The incidence of grade 3-4 hematologic toxicity (2.1% vs. 25%, p=0.001) and grade 3-4 mucositis (9.3% vs. 37.5%, p=0.002) during radiotherapy was higher in concurrent group. Conclusion: Concurrent chemoradiotherapy showed a trend of improvement in short-term survival and treatment response when compared with induction chemotherapy and radiotherapy in locally advanced head and neck cancer. A more controlled randomized trial is needed.

Background : Non-small cell lung cancer is one of the most frequent cause of death due to cancer in men, and its incidence among women is rapidly increasing. Although there has been a recent surge of interest in combined modality therapy for stageIII non-small cell lung cancer(NSCLC), the optimal treatment is still not well established. Thoracic irradiation has long been the gold standard for locally advanced unresectable NSCLC. However, although conventional radiotherapy(XRT) can palliate symptom and improve local control of disease, it has at most only a modest effect on survival. Recently, cisplatin(cis-diamminedichloroplatinum) has been reported to enhance the cell-killing effect of radiation For patients with unresectable NSCLC, cisplatin-based concurrent chemoradiotherapy(CCRT) had the advantage of therapeutic response over XRT alone and therapeutic side effect more commonly occurred in CCRT group in EORTC(European Organization for Research and Treatment of Cancer) and other trials. Objectives : We compared therapeutic response, compliance, and side effects between CCRT and XRT in patients with advanced NSCLC. Patients and Method : Thirty patients with biopsy-proven inoperable NSCLC were randomized to one of two treatment arms. Arm A consisted of XRT, radiotherapy for 4~6 weeks(1.8 Gy given 20~33 times, in five fractions a week), and arm B consisted of CCRT, radiotherapy for 2 weeks(3 Gy given to times, in five fractions a week), followed by 3 week rest period and then radiotherapy 2 more weeks(2.5 Gy given 10 times, in five fractions a week), combined with 6mg cisplatin per square meter, given daily before radiotherapy. We evaluate therapeutic response, compliance, change of performance status, side effects, and radiation pneumonitis by using the author's made scoring system. Results : There was no significant difference in therapeutic response and compliance. But there was a significantly lower laboratory complication and radiation pneumonitis in CCRT group (p < 0.05). There's significant negative correlation between stage and therapeutic response score in both groups(R=0.353, p < 0.05) In both groups, patients with squamous cell carcinoma had a tendency to higher therapeutic response score than those with adenocarcinoma. Conclusion : There was no difference between CCRT and XRT in respect to therapeutic response and compliance. But CCRT had a advantage of decreased side effects.
The aim of this study was to evaluate the clinical outcomes of radical cystectomy (RC) and concurrent chemoradiotherapy (CRT) with methotrexate, vinblastine, doxorubicin, and cisplatin (MVAC) in patients with locally advanced bladder cancer (BC). From December 2000 to February 2012, 72 patients with locally advanced BC (T3-4a, N0 or N+, M0) received either RC or CRT. RC with bilateral pelvic lymph node dissection including the common iliac region as the standard procedure. Patients in the CRT group received one cycle of MVAC followed by radiotherapy with a half dose of MVAC and then two more cycles of MVAC. Standard fractionation at a daily dose of 1.8-2.0 Gy was used, with a median total dose of 50 Gy (range, 45-60 Gy). The 3-year progression-free survival (PFS) rates in the RC and CRT groups were 56.2% and 25.6%, respectively (p=-0.015) and the 3-year overall survival (OS) rates were 63.5% and 48.1% (p=0.272). Multivariate Cox proportional hazards regression analysis with application of a propensity score indicated that RC was a significant predictor of PFS (p=0.033) but not of OS (p=0.291). Among patients with locally advanced BC, PFS was significantly prolonged in the RC group compared with the CRT group. However, RC was not a significant predictor of OS. Although the sample size in this study was small, the results suggest that patient background and postoperative quality of life should be considered when choosing treatment strategy for locally advanced BC.

Purpose: To evaluate effects of metformin on clinical outcome of non-diabetic patients with stage IV NSCLC. Materials and Methods: A prospective, randomized, open-label, controlled pilot study was conducted on patients with stage IV NSCLC with an Eastern Cooperative Oncology Group Performance Status (ECOG PS) of 0-2, excluding patients with diabetes and lactic acidosis. Thirty chemo-$na\ddot{i}ve$, non-diabetic patients with stage IV NSCLC were enrolled. Fifteen patients received intravenous gemcitabine/cisplatin regimen alone (arm B) while fifteen patients received the same regimen plus daily oral metformin 500mg (arm A). The effect of metformin on chemotherapy-response rates, survival, and adverse events in these patients was evaluated. Results: Objective response rate (ORR) and median overall survival (OS) in arms A and B were 46.7% versus 13.3% respectively, p=0.109 and 12 months versus 6.5 months, respectively, p=0.119. Median progression free survival (PFS) in arms A and B was 5.5 months versus 5 months, p=0.062. No significant increase in toxicity was observed in arm A versus arm B. Percentage of patients who experienced nausea was significantly lower in arm A versus arm B, at 26.7% versus 66.7% respectively, p=0.028. Conclusions: Metformin administration reduced occurrence of chemotherapy induced-nausea. Non-statistically significant improvements in the ORR or OS were observed. Metformin had no effect on PFS.
Purpose : We performed a retrospective analysis to compare short term results of induction chemotherapy-radiotherapy versus concurrent chemo-radiotherapy in patients with locally advanced nasopharyngeal carcinoma. Materials and Methods : From Oct. 1989 to May 1998, 62 patients with locally advanced nasopharyngeal carcinoma were treated with induction chemotherapy followed by radiotherapy (induction group) or concurrent chemo-radiotherapy (concurrent group). Induction chemotherapy was done for 50 patients, and concurrent chemotherapy for 12 patients. Age, sex, performance status, and pathologic types were evenly distributed between two groups. Stage distribution showed $32\%$ with IIB, $32\%$ with III, and $38\%$ with IV in induction group, and $50\%,\;33.3\%,\;and\;16.7\%$ in concurrent group, respectively. Chemotherapy regimen was CF (cisplatin and 5-FU) in both groups, and drug delivery method also same. Cisplatin $100\;mg/m^2$ was intravenously infused on day 1, and 5-FU $1,000\;mg/m^2$ on day $2\~6$. This was repeated at 3 weeks interval. At the end of radiotherapy, total cycles of chemotherapy were $1\~3$ (median 2) in both groups. Conventionally fractionated radiotherapy with daily fraction size $1.8\~2.0\;Gy$ and 5 fractions/week was done. Total dose was $69.4\~86\;Gy$(median 73.4 Gy) for induction group, and $69.4\~75.4\;Gy$ (median 70.8 Gy) for concurrent group. Follow-up time was $9\~116$ months (median 40.5 months) for induction group, $14\~29$ months (median 21 months) for concurrent group, respectively. Results : Overall 2 year survival rate (2YSR) for all patients was $78.7\%$. According to treatment modality, 2YSR were $77\%$ for induction group, $87\%$ for concurrent group (p>0.05). 2 year disease-free survival rate were $56\%$ and $81\%\;(p>0.05)$, respectively. Complete response to treatment were $75.5\%$ for induction group and $91.7\%$ for concurrent group, but there was no statistical difference. The incidence of grade $3\~4$ hematologic toxicity during radiotherapy was not differ between two groups, but grade 2 leukopenia was more frequent in concurrent group $(18\%\;vs\;66.7\%)$Grade $3\~4$ mucositis was more frequent in concurrent group $(4.0\%\;vs\;33.3\%)$. Overall incidence of grade $3\~4$ acute toxicity during radiotherapy was more frequent in concurrent group $(6.0\%\;vs\;41.7\%,\;p=0.005)$. Conclusion : Concurrent chemo-radiotherapy showed a trend of improvement in short-term survival and in treatment response when compared with induction chemotherapy-radiotherapy in locally advanced nasopharyngeal carcinoma. More controlled randomized trial are needed.

Purpose: To evaluate the efficacy of dolasetron mesylate in controlling nausea and vomiting in the first 24 hours and to extend these comparisons over the next 4 days in patients receiving moderately emetogenic chemotherapy. Methods: This was a single center, open-labeled study with single arm. Dolasetron (1.8 mg/kg) was given intravenously (I.V.) prechemotherapy with 10 mg of dexamethasone IV, followed 24 hours later by oral dolasetron (200 mg once daily) for the subsequent 4 days. The frequency of vomiting, severity of nausea and the presence of rescue antiemetics were assessed daily. Results: Of 30 patients enrolled, 28 were eligible and evaluable for the efficacy. Four out of 28 patients had complete control of nausea and vomiting without any rescue antiemetics through 5 days. The complete control got better as time went by with the rates of 17.9/46.4/42.9/53.6/60.7% on days 1 to 5. Vomiting was better controlled than nausea in both cisplatin-containing and non-containing chemotherapy. The adverse events were mild to moderate degrees of headache, diarrhea and fever, but were recovered spontaneously. Conclusion: Dolasetron was effective and safe for the control of nausea and vomiting in the patients with moderately emetogenic chemotherapeutic agents.
