  • Background/Objectives: The efficacy of radiotherapy alone versus chemoradiotherapy has been studied in patients with T2N0M0 laryngeal squamous cell carcinoma. Materials & Methods: Thirty nine patients with newly diagnosed T2N0M0 laryngeal squamous cell carcinoma were treated with either radiotherapy(RT group, 66-70Gy) or chemoradiotherapy(CRT group, cisplatin based concurrent chemoradiation with or without 2 cycles induction chemotherapy including cisplatin, $5-FU{\pm}$ docetaxel / radiation therapy same with above mentioned). The mean follow-up was 73.5 months. Results: The overall survival (OS), disease specific survival (DSS), disease free survival (DFS), and larynx preservation survival (LPS) at 5 years were 70%, 79%, 67%, and 71%. The complete response rate was 82.4% in RT group, and was 95.5% in CRT group. OS (57% vs 80%), DSS (69% vs 86%), DFS (52% vs 77%), and LPS (63% vs 77%) at 5 years were higher in CRT group than RT group, but it was not statistically significant. In subsite analysis, CRT group tends to improve DFS, compared to RT group, in glottic cancer (p=0.06). The toxicities were tolerable and no fatal case was observed in both groups. Conclusion: Chemoradiotherapy is effective as primary therapy for T2 laryngeal squamous cell carcinoma and showed manageable treatment induced toxicity.

  • Background: Complementary and alternative medicine (CAM) has been used frequently, and its use continues to increase in lung cancer patients, despite insufficient scientific of its efficacy. To investigate this situation, we analyzed the current awareness and use of CAM in Korean lung-cancer patients. Methods: This prospective survey-based study was performed at seven medical centers in South Korea between August and October 2019. The survey assessed general patient characteristics and the awareness and use of CAM. We analyzed differences in the clinical parameters of patients aware and not aware of CAM and of CAM non-users and users. Results: Of the 434 patients included in this study, 68.8% responded that they were aware of CAM and 30.9% said they had experienced it. In univariate analysis, the patients aware of CAM were younger with poor performance status, had advanced-stage lung cancer, received more systemic therapy, and received concurrent chemoradiation therapy (CCRT). By multiple logistic regression, younger age, poor performance status, advanced stage, and prior CCRT were identified as independent risk factors for CAM awareness. There were no significant differences in the general characteristics and cancer-associated clinical parameters of CAM non-users and users. Conclusion: Specific clinical parameters were associated with patients' awareness of CAM, although there were no significantly different characteristics between CAM users and non-users.

  • Objective: Adequate methods of combining T2-weighted imaging (T2WI) and diffusion-weighted imaging (DWI) to assess complete response (CR) to chemoradiotherapy (CRT) for rectal cancer are obscure. We aimed to determine an algorithm for combining T2WI and DWI to optimally suggest CR on MRI using visual assessment. Materials and Methods: We included 376 patients (male:female, 256:120; mean age ± standard deviation, 59.7 ± 11.1 years) who had undergone long-course CRT for rectal cancer and both pre- and post-CRT high-resolution rectal MRI during 2017-2018. Two experienced radiologists independently evaluated whether a tumor signal was absent, representing CR, on both post-CRT T2WI and DWI, and whether the pre-treatment DWI showed homogeneous hyperintensity throughout the lesion. Algorithms for combining T2WI and DWI were as follows: 'AND,' if both showed CR; 'OR,' if any one showed CR; and 'conditional OR,' if T2WI showed CR or DWI showed CR after the pre-treatment DWI showed homogeneous hyperintensity. Their efficacies for diagnosing pathologic CR (pCR) were determined in comparison with T2WI alone. Results: Sixty-nine patients (18.4%) had pCR. AND had a lower sensitivity without statistical significance (vs. 62.3% [43/69]; 59.4% [41/69], p = 0.500) and a significantly higher specificity (vs. 87.0% [267/307]; 90.2% [277/307], p = 0.002) than those of T2WI. Both OR and conditional OR combinations resulted in a large increase in sensitivity (vs. 62.3% [43/69]; 81.2% [56/69], p < 0.001; and 73.9% [51/69], p = 0.008, respectively) and a large decrease in specificity (vs. 87.0% [267/307]; 57.0% [175/307], p < 0.001; and 69.1% [212/307], p < 0.001, respectively) as compared with T2WI, ultimately creating additional false interpretations of CR more frequently than additional identification of patients with pCR. Conclusion: AND combination of T2WI and DWI is an appropriate strategy for suggesting CR using visual assessment of MRI after CRT for rectal cancer.

  • Background: Cervical esophageal cancer is a rare malignancy that requires specialized care. While definitive chemoradiation is the standard treatment approach, surgery remains a valuable option for certain patients. This study examined the surgical outcomes of patients with cervical esophageal cancer. Methods: The study involved a retrospective review and analysis of 24 patients with cervical esophageal cancer. These patients underwent surgical resection between September 1994 and December 2018. Results: The mean age of the patients was 61.0±10.2 years, and 22 (91.7%) of them were male. Furthermore, 21 patients (87.5%) had T3 or T4 tumors, and 11 (45.8%) exhibited lymph node metastasis. Gastric pull-up with esophagectomy was performed for 19 patients (79.2%), while 5 (20.8%) underwent free jejunal graft with cervical esophagectomy. The 30-day operative mortality rate was 8.3%. During the follow-up period, complications included leakage at the anastomotic site in 9 cases (37.5%) and graft necrosis of the gastric conduit in 1 case. Progression to oral feeding was achieved in 20 patients (83.3%). Fifteen patients (62.5%) displayed tumor recurrence. The median time from surgery to recurrence was 10.5 months, and the 1-year recurrence rate was 73.3%. The 1-year and 3-year survival rates were 75% and 33.3%, respectively, with a median survival period of 17 months. Conclusion: Patients with cervical esophageal cancer who underwent surgical resection faced unfavorable outcomes and relatively poor survival. The selection of cases and decision to proceed with surgery should be made cautiously, considering the risk of severe complications.

  • Background: This retrospective study aimed to determine the treatment patterns and the surgical and oncologic outcomes after completion lobectomy (CL) in patients with locoregionally recurrent stage I non-small cell lung cancer (NSCLC) who previously underwent sublobar resection. Methods: Data from 36 patients who initially underwent sublobar resection for clinical, pathological stage IA NSCLC and experienced locoregional recurrence between 2008 and 2016 were analyzed. Results: Thirty-six (3.6%) of 1,003 patients who underwent sublobar resection for NSCLC experienced locoregional recurrence. The patients' median age was 66.5 (range, 44-77) years at the initial operation, and 28 (77.8%) patients were men. Six (16.7%) patients underwent segmentectomy and 30 (83.3%) underwent wedge resection as the initial operation. The median follow-up from the initial operation was 56 (range, 9-150) months. Ten (27.8%) patients underwent CL, 22 (61.1%) underwent non-surgical treatments (chemotherapy, radiation, concurrent chemoradiation therapy), and 4 (11.1%) did not receive treatment or were lost to follow-up after recurrence. Patients who underwent CL experienced no significant complications or deaths. The median follow-up time after CL was 64.5 (range, 19-93) months. The 5-year overall survival (OS) and post-recurrence survival (PRS) were higher in the surgical group than in the non-surgical (p<0.001) and no-treatment groups (p<0.001). Conclusion: CL is a technically demanding but safe procedure for locoregionally recurrent stage I NSCLC after sublobar resection. Patients who underwent CL had better OS and PRS than patients who underwent non-surgical treatments or no treatments; however, a larger cohort study and long-term surveillance are necessary.

  • Purpose: To investigate the patterns of care for patients with nasopharyngeal carcinoma (NPC) in South Korea. Materials and Methods: A multi-institutional retrospective study was performed (Korean Radiation Oncology Group [KROG] 11-06) on a total of 1,445 patients from 15 institutions. Results: Of the 1,445 patients, more than half were stages III (39.9%) and IV (35.8%). In addition to patterns of care, we also investigated trends over time with the periods 1988-1993, 1994-2002, and 2003-2011. The frequencies of magnetic resonance imaging and positron emission tomography-computed tomography were markedly increased in the third period compared to previous 2 periods. Concurrent chemoradiation (CCRT) was performed on 894 patients (61.9%), neoadjuvant chemotherapy on 468 patients (32.4%), and adjuvant chemotherapy on 366 patients (25.3%). Of stage II-IV patients, CCRT performed on 78.8% in 2003-2011 compared to 15.0% in 1988-1993. For patients treated with CCRT, cisplatin was the most commonly used agent in 81.3% of patients. Over the periods of time, commonly used radiotherapy (RT) techniques were changed from 2-dimensional RT (1988-1993, 92.5%) to 3-dimensional RT (2003-2011, 35.5%) or intensity-modulated RT (IMRT; 2003-2011, 56.5%). Median RT doses given to primary tumors, high-risk lymphatics, and low-risk lymphatics were 70.0 Gy, 58.1 Gy, and 48.0 Gy, respectively. Adoption of IMRT increased the dose per fraction and escalated total radiation dose. Conclusion: Assessment of the patterns of care for NPC patients in South Korea demonstrated that management for NPC including diagnostic imaging, treatment regimen, RT techniques and dose schedule, advanced in accordance with the international guidelines.

  • 가톨릭의대 강남성모병원 치료방사선과에서는 1983년 3월부터 1990년 12월까지 74명이 식도암으로 진단되어 방사선치료를 받았다. 이중 6명은 추적소실되었고, 13명은 치료중단되어 55명에 대한 후향적 분석을 했다. 이중 32명은 근치적 방사선치료를 받았고, 12명은 대증적 방사선치료를 받았으며, 10명은 수술후 방사선치료를 받았다. 나머지 1명은 수술 전후로 방사선치료를 실시 했다. 55명중 28명은 방사선치료 단독으로, 27명은 방사선과 약물 병용요법으로 치료했다. 근치적 방사선치료받은 32명중 88%의 환자에서 관해를 얻었으며, 이중 완전관해는 19%, 부분관해는 69%였다. 전체 환자의 평균생존기간과 2년 생존율은 15.6개월과 22%였다. 성별, 나이, 병리학적 분화도, 종양위치, 크기, 병기, 방사선치료목적, 관해정도, 방사선 치료선량, 약물요법 병용유무, 치료시작시와 치료종결시의 연하곤란정도가 생존율에 미치는 영향을 조사했다. 이중 종양의 크기, 병기, 관해정도가 가장 큰 예후인자였으며 특이한 점은 수술후 방사선치료의 평균생존기간과 2년 생존율은 24.7개월과 63%로 근치적 방사선치료후 완전관해를 얻었을 때의 평균생존기간과 2년 생존율 29.1개월과 43%에 유사한 좋은 결과를 보여 줬다. 이는 아마도 수술받은 환자의 선별된 선택에 기인한 것으로 생각되고, 또한 연하곤란의 정도는 치료시작 때보다 치료종결시의 연하곤란정도가 예후에 약간의 영향을주었다. 또한 근치적 방사선 치료의 경우 60 Gy이상 줬을 때가 그 이하로 치료했을 때보다 좋은 생존율을 얻었으나 통계적 의의는 없었다. 대증적 방사선치료의 경우, 75%에서 연하곤란의 개선을 보였고, 평균지속기간은 10.6개월이었다.

  • 목 적: 직장암에서 수술 전 항암화학방사선치료는 수술 후 항암화학방사선치료에 비하여 치료 성적은 비슷하며 독성은 낮아 최근에 많이 시행되고 있다. 본 연구에서는 수술 전 항암화학방사선치료 시 병행한 항암화학요법 중 적정 요법과 적정 이하의 비적정 요법에 따른 치료 결과를 알아보고자 하였다. 대상 및 방법: 2003년 4월부터 2006년 4월까지 수술 전 항암화학방사선치료와 수술을 시행한 환자 중 수술 병리결과 확보가 가능하고 단일 제제 화학요법을 시행한 환자 43명을 대상으로 하였다. 방사선치료는 전 골반에 41.4~50.4 Gy (중앙값, 45 Gy), 종양에 추가조사 0~5.4 Gy (중앙값, 5.4 Gy), 총 41.4~50.4 Gy (중앙값, 50.4 Gy)를 시행하였다. 적정군은 5-fluorouracil (5-FU) 500 mg/$m^2$/day를 방사선치료 첫 3일 동안과 5주 후 3일 동안에 반복 급속 정주 한 6명과 경구 capecitabine을 방사선 치료일에 사용한 6명으로 총 12명이었다. 비적정군은 동일량의 5-FU를 방사선치료 첫 3일에만 급속 정주한 31명이었다. 수술은 방사선치료가 끝난 뒤 40~71일(중앙값, 58일)에 시행하였고 36명은 하전방절제술을, 7명은 복회음절제술을 시행하였다. 결 과: 적정군과 비적정군 사이에, 치료반응 등급 3 이상의 치료반응(83.3% vs. 67.7%, p=0.456), 수술 전과 비교한 수술 후의 병기하강(75.0% vs. 67.7%, p=0.727), 주변절제연 2 mm 초과의 획득(66.7% vs. 83.9%, p=0.237) 등에서 통계적으로 유의하게 차이를 보이지는 않았으나, 병변의 위치가 항문에서 5 cm 이내에 위치한 경우 비적정군에서 괄약근 보존 수술을 시행한 비율이 적정군에 비하여 더 낮은 경향을 보였다(75% vs. 100%, p=0.068). 모든 환자에서 3도 이상의 독성은 관찰되지 않았다. 결 론: 비적정군에서 치료에 수반되는 독성은 낮았으나 모두 2도 이하였고, 항문에서 5 cm 이내에 위치한 직장암의 수술 시 괄약근 보존 수술률이 더 낮은 경향을 보여 적정 화학요법의 병행을 시행하는 것이 바람직하겠다.

  • 목 적: 동시적 항암화학방사선치료를 받은 식도암 환자의 치료성적과 예후인자를 분석하였다. 대상 및 방법: 1994년 1월부터 2007년 7월까지 식도암으로 방사선치료를 받은 환자 246명 중 근치적 목적으로 45Gy이상의 방사선치료와 함께 동시적 항암화학요법을 받았으며 생존확인이 가능하였던 78명을 대상으로 후향적 분석을 시행하였다. AJCC 병기 IIA~IVB까지의 환자를 대상으로 하였는데, IVB는 상부식도암이 아닌 환자에서 쇄골상부림프절 전이가 있거나 하부식도암이 아닌 환자에서 복강림프절 전이가 있는 경우만을 포함시켰다. 방사선치료는 중앙값 54 Gy를 조사하였고, 항암화학요법은 대부분의 환자(88%)에서 5-FU와 cisplatin (FP) 병합요법으로 시행되었다. 추적관찰기간은 2~117개월(중앙값 14개월)이었다. 결 과: 흉부단층촬영이나 식도내시경을 통해 치료에 대한 반응을 확인할 수 있었던 54명의 환자중 완전관해가 17명, 부분관해가 18명이었다. 완전관해를 보인 환자에서 재발할 때까지의 기간은 중앙값 20개월이었고 첫 재발부위로 국소재발이 3명, 원격전이가 7명이었다. 1년, 2년, 5년 전체 생존률은 각각 58.9%, 21.7%, 12.2%이었고 중앙 생존기간은 14개월이었다. 전체 생존률에 대한 단변량분석에서 치료에 대한 반응과 FP병합요법의 횟수가 통계적인 유의성을 보여주었다. 환자의 숫자가 적었으나 방사선감작제로 일단위 혹은 주단위의 cisplatin이 FP 병합요법보다 좋은 결과를 보였다. 결 론: 원격장기로의 전이가 없는 국소진행성 식도암 환자에서 동시적 항암화학방사선치료는 기존의 연구와 유사한 결과를 보여주었다. 일단위 혹은 주단위의 cisplatin이 전신상태가 FP 병합요법에 적절하지 않은 환자에서 대안으로 사용될 수 있을 것으로 생각된다.
