OBJECTIVE: The objective of the study was to assess nutritional status among radiation oncology outpatients. METHODS: A total of 394 consecutive oncology outpatients who were screened for nutritional status through nutritional risk screening (NRS) 2002 during their admission to 12 radiation oncology centers across Turkey in October 2018 were included in this cross-sectional screening study. Data on cancer type, time of diagnosis (former and newly diagnosed), and NRS 2002 scores were recorded. Patients with NRS 2002 scores =3 were considered to be at risk of malnutrition necessitating the provision of nutritional intervention. NRS 2002 scores were evaluated in the overall study population as well as according to cancer types and time of diagnosis. RESULTS: NRS 2002 assessment (scores ≤3) revealed 133 (33.8%) patients to be at risk for malnutrition. The highest rates for malnutrition risk were noted for patients with lung cancer (43.8%), head-and-neck cancer (43.5%), and gastrointestinal tumors (42.7%). Poor nutritional status was evident in 36.0% and 25.3% of newly diagnosed and former cancer patients, respectively (p=0.067). CONCLUSION: This screening study revealed malnutrition risk and need for nutritional intervention in 33.8% of cancer patients, including 36.0% of newly diagnosed patients. A need for nutritional intervention was evident in two out of every five patients with newly diagnosed cancer, emphasizing the importance of screening for nutritional risk in every cancer patient at the time of initial diagnosis given the role of appropriate multimodal nutritional intervention before anti-cancer therapy in the long-term success.

Background: In this study, we aimed to evaluate the factors that contribute to survival outcomes in patients with thymoma treated with multimodal approaches., Methods: A total of 203 patients (105 males, 98 females; median age: 49 years; range, 17 to 77 years) with Masaoka-Koga Stage II-IV thymoma between January 2002 and December 2018 were retrospectively analyzed. Data including diagnosis of myasthenia gravis, diagnosis of diabetes mellitus, disease stage, histological type of tumor, capsule invasion and surgical margin status, lymphadenectomy, adjuvant radiotherapy or chemotherapy, time from surgery to the first day of adjuvant treatment, length of hospital stay, and overall and disease-free survival rates were recorded., Results: Of the patients, 91 had Stage II, 67 had Stage III, and 45 had Stage IV disease. A total of 123 patients (61%) had myasthenia gravis. Seventy-six patients received adjuvant radiotherapy and 48 patients received either neoadjuvant (n=35) or adjuvant (n=25) chemotherapy. Higher disease stage, presence of R1 resection, and treatment with chemotherapy were significant factors for decreased disease-free survival time. Older age, higher disease stage, longer postoperative hospital stay, chemotherapy, and disease recurrence were effective contributors to decreased overall survival time. Adjuvant radiotherapy had a statistically significant positive effect on overall survival only in patients with completely resected Stage IV disease (five-year overall survival: 94.7% vs. 79.1%, respectively; p=0.015). In the multivariate analysis, older age (hazard ratio: 4.26), higher disease stage (hazard ratio: 2.95), and longer hospitalization time (hazard ratio: 3.81) were significant prognostic factors for overall survival. Patients with local recurrence who underwent complete resection had a survival time comparable to non-recurrent patients (p=0.753)., Conclusion: For patients with thymoma, higher disease stage, age ≥50 years, longer hospitalization, and need for chemotherapy are associated with worse survival rates. Adjuvant chemotherapy has a positive impact on Stage IV disease. Resection of recurrent lesions has a valuable impact on survival., Competing Interests: Conflict of Interest: The authors declared no conflicts of interest with respect to the authorship and/or publication of this article., (Copyright © 2021, Turkish Society of Cardiovascular Surgery.)

Background/aims: To assess the effect of various parameters on the oncologic outcomes, including the time interval between therapy and surgery (S) in locally advanced rectal cancer (LARC) patients receiving preoperative chemoradiotherapy (CRT)., Materials and Methods: The data of 914 LARC patients who received preoperative CRT between 1994 and 2015 were collected retrospectively. Patients received 45-50.4 Gy RT with 5FU based chemotherapy (CT). They all underwent radical resection followed by maintenance CT. Clinical and pathologic variables were compared between the pCR and no-pCR groups. Survival was estimated by the Kaplan-Meier method and Cox proportional hazard model was used in multivariate analysis., Results: After median follow-up of 60.5 (range=12-297.6) months, median overall survival (OS) was 58.75 months and disease-free survival (DFS) 53.32 months. pCR was observed in 18.9% of all cases. pCR, lymphovascular invasion and metastatic lymph node ratio (mLNR) were significantly associated with OS and DFS on multivariate analysis. The 5-year OS and DFS rates were better in pCR group (95.3% vs 80.7% for OS, p<0.0001 and 87.4% vs 71% for DFS, p<0.0001). pCR patients with 4-8 weeks interval had lower rates of distant metastasis (9% vs 20%, p=0.01) and any recurrences (13.6% vs 29.6%, p=0.001) than the remaining. Both OS and DFS were better in favor of pCR achieved at 4-8 week interval time (p<0.0001 for each)., Conclusion: pCR after preoperative CRT in LARC correlated with better oncologic outcome. The best OS and DFS durations were achieved in patients who experienced pCR after 4-8-weeks interval before surgery.

Objectives: The aim of this study was to evaluate the impact of maximum standard uptake value (SUV max ) of the primary tumor and locoregional metastatic lymph node in predicting survival in patients with the preoperative rectal adenocarcinoma., Methods: One hundred and fifteen patients [mean age ± standard deviation (SD): 58.7±11.4 years] with biopsy-proven rectal adenocarcinoma underwent 18 F-fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) imaging for the staging were included in this study. All patients were followed-up for a minimum of 12 months (mean ± SD: 29.7±13.5 months). Tumor-node-metastasis 2017 clinical staging, SUV max of the primary rectal tumor and locoregional lymph nodes on the PET/CT studies were evaluated., Results: All patients had increased FDG activity of the primary tumor. The mean ± SD SUV max of the primary tumor and locoregional metastatic lymph node were 21.0±9.1 and 4.6±2.8, respectively. Primary tumor SUV max did not have an effect on predicting survival (p=0.525) however locoregional metastatic lymph node SUV max had an effect (p<0.05) on predicting survival. Clinical stage of the disease was a factor predicting survival (p<0.001)., Conclusion: 18 F-FDG PET/CT is an effective imaging modality for detecting primary tumors and metastases in rectal adenocarcinoma and clinical stage assessment with PET/CT had an effect on predicting survival. Furthermore, in our study locoregional lymph node SUV max was defined as a factor in predicting survival.
