  • Purpose: The main objective of the present study was to evaluate the efficacy and toxicity of concurrent chemoradiotherapy followed by adjuvant chemotherapy compared with concurrent chemoradiotherapy alone in the treatment of 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. Randomized controlled trials (RCTs) that compared concurrent chemoradiotherapy followed by adjuvant chemotherapy with concurrent chemoradiotherapy alone in locoregionally advanced nasopharyngeal carcinoma were included. Meta-analysis was 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: Five studies were included. Risk ratios of 1.02 (95%CI 0.89-1.15), 0.93 (95%CI 0.72-1.21), 1.07 (95%CI 0.87-1.32), 0.95 (95%CI 0.80-1.13) were observed for 3 years overall survival, 5 years failure-free survival, 5 years locoregional failure-free survival and 5 years distant metastasis failure-free survival. There were no treatment-related deaths in both groups of five studies. Hematologic and gastrointestinal toxicity were the most significant for patients during adjuvant chemotherapy. The level of evidence was low. Conclusion: Compared with concurrent chemoradiotherapy alone, concurrent chemotherapy followed by adjuvant chemotherapy did not improve prognosis. More toxicity was found during adjuvant chemotherapy.

  • Purpose: Local recurrence is a common failure pattern in adenocarcinoma of the cecum. This study aimed to investigate the potential role of adjuvant radiation therapy on oncologic outcomes of patients with adenocarcinoma of the cecum. Materials and Methods: This retrospective study was carried out at three large tertiary university hospitals. We analyzed the characteristics, prognostic factors, and survival of 162 patients with adenocarcinoma of the cecum that were treated and followed up between 2000 and 2013. All the patients had undergone a right hemicolectomy and received chemotherapy with (n = 48) or without (n = 114) adjuvant radiation therapy. Results: The subjects were 65 females and 97 males with a median age of 56 years (range, 17 to 90 years) at diagnosis. The 5-year local control (LC), disease free survival (DFS), and overall survival (OS) rates were 72.7%, 57.2%, and 62.6% respectively. In a multivariate analysis, age, tumor stage, node stage, and adjuvant radiation therapy were determined to be independent prognostic factors. Age more than 55 years (hazard ratio [HR] = 1.0; 95% confidence interval [CI], 0.06-0.32; p = 0.003), T4 stage (HR = 6.8; 95% CI, 3.07-15.36; p < 0.001), node positive disease (HR = 4.2; 95% CI, 1.94-9.13; p < 0.001), and the absence of adjuvant radiation therapy (HR = 3.0; 95% CI, 1.39-6.46; p = 0.005) had a negative influence on OS. Conclusion: Adjuvant radiation therapy significantly improves DFS and OS in patients with adenocarcinoma of the cecum.

  • Background: Radiotherapy plays an important role as adjuvant treatment in locally advanced breast cancer and in those patients who have undergone breast-conserving surgery. This study aimed to investigate the prognostic impact of adjuvant radiation on oncologic outcomes in elderly women with breast cancer. Materials and Methods: In this retrospective study, we reviewed and analyzed the characteristics, treatment outcome and survival of elderly women (aged ${\geq}60years$) with breast cancer who were treated and followed-up between 1993 and 2014. The median follow up for the surviving patients was 38 (range 3-207) months. Results: One hundred and seventy-eight patients with a median age of 74 (range 60-95) years were enrolled in the study. Of the total, 60 patients received postoperative adjuvant radiation (radiation group) and the remaining 118 did not (control group). Patients in the radiation group were significantly younger than those in the control group (P value=0.004). In addition, patients in radiation group had higher node stage (P value<0.001) and disease stage (P=0.003) and tended to have higher tumor grade (P=0.031) and received more frequent (P value<0.001) adjuvant and neoadjuvant chemotherapy compared to those in the control group. There was no statistically significant difference between two groups regarding the local control, disease-free survival and overall survival rates. Conclusions: In this study, we did not find a prognostic impact for adjuvant radiation on oncologic outcomes in elderly women with breast cancer.

  • Purpose: To evaluate the benefit of adjuvant radiation therapy (RT) for retroperitoneal liposarcoma (RPLS) following gross tumor removal. Materials and Methods: We reviewed 77 patients with primary RPLS surgically treated between January 2000 and December 2013. Cases with gross residual disease were excluded. Tumor grade was evaluated according to the French Federation of Cancer Centers Sarcoma Group (FNCLCC) system. Adjuvant RT was delivered to 32 patients (42%) using external beam RT alone. Median follow-up time was 36 months (range, 5 to 169). Results: Among 77 patients, 33 (43%) presented with well-differentiated, 31 (40%) with de-differentiated, 8 (10%) with myxoid/round and 4 (5%) with pleomorphic morphology. The RT group included less well-differentiated subtype than surgery group (28% vs. 53%). During follow up, 34 patients (44%) showed local recurrence. Local recurrence rate was lower in the RT group (38%) compared to the surgery group (49%). The 3-year local control rate (LC) was 55.6%, and the 3-year overall survival (OS) was 82.1%. Tumor histology and FNCLCC grade were significantly associated with local recurrence. There was no statistical significance of adding adjuvant RT in LC (p = 0.312). However, patients with tumor histology other than well-differentiated subtype showed marginally decreased local recurrence rate after adjuvant RT (3-year LC, RT 43.9% vs. no RT 35.3%; p = 0.087). Conclusion: RPLS patients receiving RT experienced less local recurrence. We suggest that the addition of adjuvant RT may be related to improvement of LCs, especially in patients with non-favorable histologic subtypes.

  • Carrageena은 전세계적으로 안전한 식품첨가물로 승인되어 오랜 기간 다양한 식품, 기타 가공품에 사용되어지고 있다. 다른 한편으로, 이 Carrageenan은 동물 실험에서 염증 유도 물질로 확인되어 염증 유발 실험에 현재까지도 매우 빈번히 사용 되고 있다. 또한 이 Carrageenan을 고온과 강산에서 처리하여 부분적으로 분해한 degraded Carrageenan은 염증 유도 능이 Carrageenan 보다 더 강한 것으로 알려져 있다. 면역 보강제의 중요한 특성 가운데 하나는 선천면역(대표적으로 염증반응)의 활성화 인 것이 잘 알려져 있다. 그러나 현재까지 Carrageenan이나 degraded Carrageenan의 면역 보강제로서의 효과에 관하여 상세한 비교 연구는 수행되어 지지 않았다. 본 연구의 목적은 Carrageenan과 degraded Carrageenan의 면역 보강제로서의 효과를 비교 분석하는데 있다. 실험 동물은 마우스를 사용하였으며, 난 알부민을 항원으로, 피하면역을 수행하여 각각의 면역 보강제 효과를 항체 형성 정도로 조사하였다. Carrageenan이나 degraded Carrageenan 모두 항원 단독으로 면역한 것과 비교할 때 유의적으로 높은 IgG 생성 능을 보였다. 추가적으로 항원 특이적 IgG1과 IgG2a를 조사한 결과, 이들 Carrageenan, degraded Carrageenan은 본 실험에서 양성 대조 군으로 사용한 보강제, Complete Freund's adjuvant와 비교 할 때 IgG2a 보다는 IgG1 생성 능이 높게 유도되는 것이 확인되었다. 이들 결과를 종합하면 염증 유발 능이 보다 강한 degraded carrageenan의 면역 보강제 효과는 carrageenan과 유사한 정도로 확인되었으며, 이들 모두 IgG2 보다는 IgG1 생성 효과가 강한 것으로 나타났다.

  • Purpose: Various postoperative adjuvant chemotherapy regimens have been proposed for the patients with advanced gastric cancer. The majority of clinical trials have shown no significant difference in the survival benefit. The aim of this study was to compare the survival rates of postoperative adjuvant chemotherapies used in stage III gastric cancer patients who received curative gastrectomy. Materials and Methods: Between 1990 and 1999, a survival analysis was performed in 260 patients who received curative gastric resection and postoperative adjuvant chemotherapy. The patients were divided into four groups according to the chemotherapeutic regimens received. The groups were: the F group: furtulon alone, FM group: furtulon and mitomycin, FAM group: 5-FU, adriamycin and mitomycin, FLEP group: 5-FU, leucovorin, etoposide and cisplatin. The survival rates were analyzed using the Kaplan-Meier method and the Cox proportional hazards model. Results: There were no differences among the groups of patients with regard to tumor characteristics except for lymph node metastasis and the ratio of metastasis to lymph nodes. In the FLEP group, the ratio of metastasis to lymph nodes was higher than in the other groups. The five and ten year survival rates of F, FM, FAM and FLEP were 51.9%, 28.9%, 59.5%, 49.8%, 66.1%, 57.4% and 30.0%, 27.5%, respectively. The univariate analysis showed that age, Borrmann type, lymph node metastasis, ratio of metastasis to lymph nodes, postoperative adjuvant chemotherapy and recurrence were significant factors for survival. For the multivariate analysis, recurrence, age, Borrmann type, ratio of lymph node metastasis and lymph node dissection were independent prognostic factors; however, the postoperative adjuvant chemotherapy was not an independent prognostic factor. Conclusion: The FAM regimen was the most beneficial postoperative adjuvant chemotherapy for improved survival rates; the FM regimen was the second and the FLEP regimen was the last. In order to determine the effectiveness of postoperative adjuvant chemotherapy in stage III gastric cancer, well designed prospective studies including a surgery only group will be needed.

  • Background: The standard therapy for stage I rectum cancer is surgical resection. Currently, there is no strong evidence to suggest that any type of adjuvant therapy is beneficial. The risks of local relapse and distant metastasis are higher in rectal tumors. Therefore, while there is no clearly defined absolute indication for adjuvant therapy in lymph node negative colon cancers, rectum tumors that are T3N0 and higher require adjuvant treatment. Due to the more aggressive nature of rectal cancers, we explored the clinical and pathologic factors that could predict the risk of relapse in Stage I (T1-T2) disease and whether there was any progression-free survival benefit to adjuvant therapy. Materials and Methods: This multicenter study was carried out by the Anatolian Society of Medical Oncology. A total of 178 patients with rectal cancers who underwent curative surgery between January 1994 and August 2012 in 13 centers were included in the study. Patient demographics, including survival data and tumor characteristics were obtained from medical charts. Results: The median age was 58 years (range 26-85 years). Most tumors were well or moderately differentiated. For adjuvant treatment, 13 patients (7.3%) received radiotherapy alone, 12 patients (6.7%) received chemotherapy alone and 15 patients (8.4%) were given chemoradiotherapy. Median follow up was 29 months (3-225 months). Some 42 patients (23.6%) had relapse during follow up; 30 with local recurrence (71.4%) whereas 12 (28.6%) were distant metastases. Among the patients, 5-year DFS was 64% and OS was 82%. Mucinous histology and receiving adjuvant therapy were found to have statistically insignificant correlations with relapse and survival. Conclusions: In our retrospective analysis, approximately one quarter of patients exhibited either local or systemic relapse. The rates of relapse were slightly higher in the patients who had no adjuvant therapy. There may thus be a role for adjuvant therapy in high-risk stage I rectal tumors.
