목적 : 국소 진행된 비인강암으로 유도 화학요법 혹은 동시 화학요법 및 방사선 치료를 받은 환자들의 부작용 및 단기 생존율을 비교하기 위하여 본 연구를 시행하였다. 대상 및 방법 : 1989년 10월부터 1998년 5월까지, 비인강암으로 진단받고 유도 화학요법 혹은 동시 화학요법 및 방사선 치료를 받은 62명의 환자들을 대상으로 후향적 분석을 시행하였다. 유도 화학요법군은 50명, 동시 화학요법군은 12명이었다. 나이, 성, 전신 수행능력, 조직학적 유형 등은 양군에서 비교적 고르게 분포하였다. 병기 분포는, 유도 화학요법군의 경우 IIB가 $32\%$, III가 $30\%$, 그리고 IV가 $38\%$였으며, 동시 화학요법군은 각각 50, 33.3, $16.7\%$였다. 양군에서 화학요법 약제는 CF (cisplatin and 5-FU)였고, 약제 투여 방법은 동일하였다. Cisplatin $100\;mg/m^2$을 day 1에, 5-FU $1,000\;mg/m^2$을 day $2\~6$에 각각 정맥투여하였으며 3주 간격으로 반복하였다. 방사선 치료 종료시까지 시행된 화학요법의 횟수는 양군 모두 테$1\~3$회(중앙값 2회)였다. 방사선 치료는 양군 모두 일일선량 $1.8\~2.0\;Gy$를 주 5회 조사하였다. 총 방사선량은, 유도 화학요법군의 경우 $69.4\~86\;Gy$ (중앙 선량 73.4 Gy), 동시 화학요법군은 $69.4\~75.4\;Gy$ (중앙 선량 70.8 Gy)였다. 추적기간은, 유도 화학요법군의 경우 $9\~l16$개월(중앙값 40.5개월), 동시 화학요법군은 $14\~29$개월(중앙값 21개월)이었다. 결과 : 전체 환자에서 2년 생존율은 $78.7\%$였다. 치료 방법별 2년 전체 생존율은, 유도 화학요법군이 $77\%$, 동시 화학요법군은 $87\%$였으며(p>0.05), 2년 무병 생존율은 각각 $56\%$ 와 $81\%$였다(p>0.05). 최종 치료에 대한 완전 관해율은 $75.5\%$와 $91.7\%$로 동시 화학요법군에서 높았으나 통계학적 유의성은 없었다. 방사선 치료시 grade $3\~4$의 혈액학적 독성은 양군에서 차이가 없었고, grade 2의 백혈구 감소가 동시 화학요법군에서 많았다 $(18\%\;vs\;66.7\%)$. Grade $3\~4$의 점막염은 동시 화학요법군에서 많았다$(4.0\%\;vs\;33.3\%)$. 전체적으로 grade $3\~4$의 급성 부작용이 동시 화학요법군에서 빈번하였고$(6.0\%\;vs\;41.7\%,\;p=0.005)$, 부작용으로 사망한 경우는 없었다. 결론 : 국소 진행된 비인강암에서 동시 화학요법을 시행함으로써 치료의 반응율과 2년 무병 생존율이 향상되는 경향을 보였으나, 통계학적 의의는 없었다. 따라서, 좀더 많은 대조군과 장기 추적관찰이 요구된다.

Purpose: To evaluate the efficacy and toxicity of induction chemotherapy followed by concurrent chemoradiotherapy (the treatment group) versus concurrent chemoradiotherapy with or without adjuvant chemotherapy (the control group) for locoregionally advanced nasopharyngeal carcinoma. Methods: The search strategy included Pubmed, Embase, the Cochrane Library, China National Knowledge Internet Web, Chinese Biomedical Database and Wanfang Database. We also searched reference lists of articles and the volumes of abstracts of scientific meetings. All randomized controlled trials were included for a meta-analysis performed with RevMan 5.1.0. The Grading of Recommendations Assessment, Development, and Evaluation system (GRADE) was used to rate the level of evidence. Results: Eleven studies were included. Risk ratios of 0.99 (95%CI 0.72-1.36), 0.37 (95%CI 0.20-0.69), 1.08 (95%CI 0.84-1.38), 0.98 (95%CI 0.75-1.27) were observed for 3 years overall survival, 3 years progression-free survival, 2 years loco-regional failure-free survival and 2 years distant metastasis failure-free survival. There were no treatment-related deaths in either group in the 11 studies. Risk ratios of 1.90 (95%CI 1.24-2.92), 2.67 (95%CI 0.64-11.1), 1.04 (95%CI 0.79-1.37), 0.98 (95%CI 0.27-3.52) were found for grade 3-4 leukopenia, grade 3-4 thrombocytopenia, grade 3-4 mucous membrane, and grade 3-4 hepatic hematologic and gastrointestinal toxicity, the most significant toxicities for patients. Conclusion: Compared with the control group, induction chemotherapy followed by concurrent chemoradiotherapy was well tolerated but could not significantly improve prognosis in terms of overall survival, loco-regional failure-free survival or distant metastasis failure-free survival.

Concurrent chemoradiation therapy (CCRT) has played the most important and central role in the definitive therapy for the patients with locoregionally advanced stage nasopharynx cancer. The addition of induction chemotherapy (IC) or adjuvant chemotherapy (AC) to CCRT have been widely accepted with the rationale of improving distant control in the clinical practices. This review article investigated the role of IC and AC based on 11 recent meta-analysis publications, and found that the clinical benefits obtained by the additional IC or AC to CCRT, at the cost of the increased risks of more frequent and more severe side effects, seemed not big enough. More intervention is not always better, however, less seems frequently good enough. The author would speculate that 'less is more' and would advocate CCRT alone as the current standard.

The purpose of this study was to investigate whether whole-liver radiotherapy plus a tumor-boost dose with concurrent chemotherapy is beneficial for colorectal cancer patients with massive and multiple liver metastases. From January 2007 to December 2012, 19 patients who exhibited massive (with a longest diameter > 5 cm) and invasive liver metastases and multiple metastases were treated with radiotherapy and concurrent chemotherapy. The total radiation dose was 53.4 Gy (range 38.8 Gy-66.3 Gy). All of the patients received a continuous intravenous dose of 5 fluorouracil (5-FU) 225 mg/m2 concurrently with radiation. The median survival time was 19 months. The 1- and 2- year overall survival rates were 78.3% and 14.3%, respectively. Of all of the patients who presented with abdominal pain, 100% experienced a decrease in pain. Decreases in the rates of ascites and jaundice were confirmed by ultrasound and bilirubin levels. No cases of Grade 4 or 5 acute or late toxicity were recorded. There were only two cases of Grade 3 toxicity (elevated bilirubin). These data provide evidence that whole-liver radiotherapy plus a tumor-boost dose with concurrent chemotherapy is beneficial for colorectal cancer patients with massive and multiple liver metastases.

Aim: The objective of this study is to investigate prognostic factors affecting survival of patients undergoing concurrent or sequential chemoradiotherapy (CRT) for stage III non-small-cell lung cancer (NSCL). Methods and materials: We retrospectively reviewed the clinical records of 148 patients with advanced, inoperable stage III NSCLC, who were treated between 2007 and 2015. Results: The median survival was found to be 19 months and 3-year overall survival was 27%. Age (<65 vs ${\geq}65years$, p=0.026), stage (IIIA vs IIIB, p=0.033), dose of radiotherapy (RT) (<60 vs ${\geq}60Gy$, p=0.024) and treatment method (sequential chemotherapy+RT vs concurrent CRT, p=0.023) were found to be factors affecting survival in univariate analyses. Gender, histological subtype, weight loss during CRT, performance status, induction/consolidation chemotherapy and presence of comorbidities did not affect survival (p>0.050). Conclusion: Young age, stage IIIA, radiotherapy dose and concurrent chemoradiotherapy may positively affect survival in stage III NSCL cases.

Among the 63 patients with histopathologically proven primary squamous cell anal cancer who were managed in Presbyterian Medical Center and Yonsei University Cancer from Jan. 1971 to Dec. 1991, 34 patients, who were managed with surgery alone(abdominoperineal resection) or post-operative radiotherapy and concurrent chemoradiotherapy were analysed. With mean follow up time of 81.3 months, 30 Patients(88$ \% $) were followed up from 17 to 243 months. In methods, 10 patients were treated with surgery alone. 9 Patients were treated with combined surgery and postoperative radiotherapy(50$\∼$60 Gy in 28$\∼$30 fractions). 15 patients were treated with concurrent chemoradiotherapy. Chemotherapy (Mitomycin C 15 mg/squ, bolus injection day 1;5-FU, 750 mg/squ, 24hr infusion, day 1 to 5) and radiotherapy started the same day. A dose of 30 Gy was given to the tumor and to the pelvis including inguinal nodes, in 15 fractions. After 2 weeks a boost of radiotherapy(20 Gy) to the ano-perineal area and second cycle of chemotherapy completed the treatment. The overall 5-year survival rate was 56.2$ \% $. Concurrent chemoradiotherapy group was 70$ \% $ and surgery alone group was 16.7$ \% $. According to the cox proportional harzard model, there was significant difference between survival with concurrent chemoradiotherapy and surgery alone(p=0.0129), but post-operative radiotherapy was 64.8$ \% $, which was not stastically significant(p=0.1412). In concurrent chemoradiotherapy group, the anal funtion Preservation rate was 87$ \% $ and the severe complication rate(grade 3 stenosis and incontinence) was 13.3$ \% $. In conclusion, we conclude that the concurrent chemoradiotherapy may be effective treatment modality in patients with anal cancer.

In patients with locally advanced head and neck cancers who do not respond to induction chemotherapy and who have locoregional recurrence after local treatment subsequent radiotherapy alone does not have any additative effect. The theoretical rationale and promising clinical response of concurrent chemoradiotherapy in patients with the head and neck cancers have been recently conducted Ten patients(9 stage IV, q stage III) were treated with concurrent chemoradiotherapy(radiotherapy start from day 1 of chemotherapy; cisplatin $100mg/m^2$ intravenously every 3 weeks for $3{\sim}4$ cycles on day 1.22 and 43..). Four patients achieved complete response(CR) and overall response rate was 80% (8/10). The major toxicities we re leukopenia (90%), nausea/vomiting(80%), stomatitis(80%) and peripheral neuropathy(30%). Most of these side effects were mild to moderate and reversible.

Purpose: This study was performed to assess the reliability and validity of the Korean version of European Organization for Research and Treatment of Cancer Quality of Life Questionnaire - Chemotherapy-induced peripheral neuropathy 20 items (EORTC QLQ-CIPN20) in patients receiving neurotoxic chemotherapy. Methods: A convenience sample of 249 Korean cancer patients, previously or currently, being treated with peripheral neurotoxic chemotherapeutic agents were asked to fill in the questionnaire. Collected data were analyzed using SPSS 21.0 and AMOS 21.0. Construct validity, known-group validity, concurrent validity, and internal consistency reliability of the Korean version of the QLQ-CIPN20 were evaluated. Results: Factor analysis confirmed 3 dimensions of CIPN: sensory, motor, and autonomic. The factor loadings of the 20 items on the 3 subscales ranged from .38 to .85. The 3 subscale-model was validated by confirmatory factor analysis (GFI=.90, AGFI=.86, RMSR=.05, NFI=.87, and CFI=.94), and concurrent validity was demonstrated with the EORTC QLQ-C30. Furthermore, the QLQ-CIPN20 established known-group validity. The Cronbach's alpha coefficients for internal consistency of the subscales ranged from .73 to .89. Conclusion: The Korean version of the EORTC QLQ-CIPN20 showed satisfactory construct, concurrent, and known-group validity, as well as internal reliability.

Objective: To explore improved treatment by retrospectively comparing survival time of gemcitabine-based concurrent chemoradiotherapy (GemRT) versus chemotherapy (Gem) alone in patients with locally advanced pancreatic cancer (LAPC). Methods: From January 2005 to June 2010, 56 patients with LAPC from Subei People's Hospital were treated either with Gem (n=21) or GemRT (n=35). Gem consisted of 4-6 cycles gemcitabine alone (1000 mg/m2 on Days 1, 8, 15, 28-day a cycle). GemRT consisted of 50.4Gy/28F radiotherapy with concurrent 2 cycles of gemcitabine (1000 $mg/m^2$ on days of radiation 1, 8, 15, 21-day a cycle). Radiation was delivered to the gross tumor volume plus 1-1.5 cm by use of a three-dimensional conformal technique. The follow-up time was calculated from the time of diagnosis to the date of death or last contact. Kaplan-Meier methodology wes used to evaluate survival. Results: Patient characteristics were not significantly different between treatment groups. The disease control rate and the objective response rate of GemRT versus Gem was 97.1% vs 71.4%, 74.3% vs 38.1%. The overall survival (OS) was significantly better for GemRT compared to Gem (median 13 months versus 8 months; 51.4% versus 14.3% at 1 year, respectively). Conclusion: Radiation therapy at 50.4Gy with 2 concurrent cycles of gemcitabine results in favorable rates of OS. Concurrent chemoradiotherapy should be the first choice for patients with LAPC.
