Aim: Although preoperative chemoradiatherapy (CRT) has proven its benefits in terms of decreased toxicity, there is still a considerable amount of cases that do not receive postoperative CRT. Oncologists at different geographic locations still need to know the long-term effects of this treatment in order to manage patients successfully. The current paper reports on long-term quality of life (QOL) and late side effects after adjuvant CRT in rectal cancer patients from 5 centers in Anatolia. Methods: Rectal cancer patients treated with postoperative CRT with minimum 1-year follow-up and were in complete remission, were evaluated according to RTOG and LENT-SOMA scales. They were also asked to complete Turkish version of EORTC QLQ-C30 questionnaire and the CR-38 module. Each center participated with the required clinical data. Results: Two hundred and thirty patients with median age of 55 years participated and completed the study. Median follow-up time was 5 years. All patients received RT concomitant with chemotherapy. Common parameters that both increased functional health scales and yielded better symptom scores were long term interval after treatment and sphincter-saving surgery. In addition, surgery type and follow-up time were determined to be predictors of QOL scores and late toxicity grade. Conclusion: Postoperative CRT was found to have a great impact on the long term QOL and side effects in rectal cancer survivors. The factors that adversely affect these are abdominoperineal resection and shorter interval. The findings may encourage life-long follow-up and cooperation with patients, which should be mentioned during the initial counseling.

Background: Chemoradiation (CRT) using cisplatin-based regimens has become the standard of care in the treatment of squamous cell head and neck cancers (SCHNC). The impact of taxanes as radiosensitizing agents with concurrent CRT regimens is unknown. We therefore retrospectively evaluated the efficacy and tolerability of a weekly cisplatin+docetaxel combination with CRT in locally advanced SCHNC. Methods: Sixty-six patients with locally advanced SCHNC (39.4% stage IV, 53% stage III, and 7.6% stage II) were assessed retrospectively. Total radiation dose to the PTV of gross disease (primary and/or node) was 70 Gy/35 fractions, 5 fractions per week. Minimum doses of 60 Gy and 50 Gy were administered to PTVs of elective high risk and low risk disease, respectively. Chemotherapy (CT) consisted of weekly cisplatin (20 $mg/m^2$)+docetaxel (20 $mg/m^2$) concurrently with RT. Results: The median age of the patients was 58 years (range, 32-77). Objective response rate was 83.3%. The 2-year progression-free survival (PFS) and overall survival (OS) were 75.7% and 78.3%, respectively. The most common grade 3 and 4 toxicities were mucositis (36.4%), nausea and vomiting (12.1%), neutropenia (4.5%). Conclusion: Weekly cisplatin and docetaxel concurrent with RT for locally advanced SCHNC was found tolerable with high efficacy.

CD133 is one of the most important stem cell markers in solid cancers and Ki-67 is a marker that reflects cell proliferation. The relationships between the expression of CD133 and Ki-67 and prognosis in gastric carcinoma are unknown and need exploring. We examined 50 gastric cancer patients retrospectively in the Radiation Oncology Department of the Faculty of Medicine, Gazi University. CD133 and Ki-67 expression was examined using immunohistochemical staining. The survival rate in patients with CD133 positive expression was significantly worse than that in the patients with negative expression (p=0.04). Expression of CD133 had a positive correlation with that of Ki-67 (r=0.350; p=0.014). Multivariate analysis revealed that the expression of CD133 was an independent prognostic factor in gastric cancer (p=0.02). Conclusion, expression of CD133 may be a useful prognostic marker in gastric cancer.

Cancer prevalance and incidence is increasing with aging of populations and age is a critical factor in decision-making for anti-cancer treatment. However it is believed that chronological age is not enough to guide management in elderly cancer patients. Multidisciplinary evaluation and comprehensive geriatric assessment has gained importance regarding the treatment selection especially for definitive anti-cancer therapy recently. We here aimed to analyse the effect of the comprehensive geriatric assessment parameters on radiotherapy toxicity and tolerability in a series of geriatric cancer patients in Turkey.

Purpose: The incidence of hepatic steatosis among children has been increasing; however, data distinguishing simple steatosis from a more complex disorder are lacking. Methods: This study identified the etiologies resulting in hepatic steatosis through a retrospective review of pediatric liver biopsies performed in the last 10 years. A total of 158 patients with hepatic steatosis proven by histopathological evaluation were enrolled in the study, and baseline demographic features, anthropometric measurements, physical examination findings, laboratory data, ultrasonographic findings, and liver histopathologies were noted. Results: The two most common diagnoses were inborn errors of metabolism (IEM) (52.5%) and nonalcoholic fatty liver disease/steatohepatitis (NAFLD/NASH) (29.7%). The three most common diseases in the IEM group were glycogen storage disorders, Wilson's disease, and mitochondrial disease. The rates of consanguineous marriage (75.6%; odds ratio [OR], 26.040) and positive family history (26.5%; OR, 8.115) were significantly higher (p=0.002, p<0.001, respectively) in the IEM group than those in the NAFLD/NASH group. Younger age (p=0.001), normal anthropometric measurements (p=0.03), increased aspartate aminotransferase levels (p<0.001), triglyceride levels (p=0.001), and cholestatic biochemical parameters with disrupted liver function tests, as well as severe liver destruction of hepatic architecture, cholestasis, fibrosis, and nodule formation, were also common in the IEM group. Conclusion: Parents with consanguinity and positive family history, together with clinical and biochemical findings, may provide a high index of suspicion for IEM to distinguish primary steatosis from the consequence of a more complex disorder.

Background: In this study we aimed to determine the rate and habitual patterns of smoking, intentions of cessation, dependence levels and sociodemographic characteristics of relatives of patients with a diagnosis of cancer. Materials and Methods: This study was designed by the Turkish Oncology Group, Epidemiology and Prevention Subgroup. The relatives of cancer patients were asked to fill a questionnaire and Fagerstrom test of nicotine dependence. Results: The median ages of those with lower and higher Fagerstrom scores were 40 years and 42 years, respectively. We found no evidence of variation between the two groups for the remaining sociodemographic variables, including the subject's medical status, gender, living in the same house with the patient, their educational status, their family income, closeness to their cancer patients or spending time with them or getting any help or wanting to get some help. Only 2% of the subjects started smoking after cancer was diagnosed in their loved ones and almost 20% of subjects had quit smoking during the previous year. Conclusions: The Fagerstrom score is helpful in determining who would be the most likely to benefit from a cigarette smoking cessation program. Identification of these people with proper screening methods might help us to pinpoint who would benefit most from these programs.
