Aim To investigate quality of life and exposure to lifestyle risk factors of cancer patients in Bosnia and Herzegovina and a correlation of cancer type with lifestyle risk factors. Methods This was a cross-sectional study conducted on 200 cancer patients from the Clinical Centre of the University of Sarajevo. The respondents completed an anonymous questionnaire consisting of seven sections: basic patient information, physical activity, dietary habits including alternative medicine, tobacco use, alcohol consumption, anxiety, and comorbidities. Results A total of 150 (75%) patients were overweight with 113 (56%) of them being less physically active after the confirmed diagnosis. After the diagnosis, 79 (40%) patients ate less food, and 154 (77%) healthier; 130 (65%) reported consumption of alternative medicine and food supplements, 39 (30%) spent >1/4 of average monthly salary on these products. Majority never consumed alcohol, 135 (68%) and 101 (51%) patients reported history of tobacco use. Being obese was an independent predictor for colorectal carcinoma; being less obese was linked to a decreased risk of breast cancer diagnosis. Physical activity was linked to a decreased risk of lung cancer diagnosis. Many patients (122; 61%) reported having chronic comorbidities, mostly hypertension, while 44 (22%) patients were proven to be clinically anxious. Conclusion Our data suggest lack of public awareness of the consequences of unhealthy lifestyles. Risk factors such as alcohol consumption and tobacco use differed from other European countries. Significance of lifestyle changes after the diagnosis for reducing mortality and cancer recurrence requires further research. Prevention programs and more data are needed., (Copyright© by the Medical Assotiation of Zenica-Doboj Canton.)

Objective: The aim of the study was to evaluate the prognostic value of the maximum standardized uptake value (SUVmax) of 18F-Fluorodeoxyglucose (18F-FDG) PET/CT in patients with metastatic colorectal cancer, and to compare it with classical prognostic markers., Materials and Methods: The study included 70 patients with metastatic colorectal cancer who had not been treated for the metastatic disease. The patients underwent 18F-FDG PET/CT as part of their routine diagnostic reevaluation. During the analysis, the value of the largest tumor diameter and SUVmax was determined for the lesion with the highest SUVmax observed. The values of CEA and CA 19-9 were recorded 7 days before the PET/CT analysis., Results: SUVmax and Carbohydrate antigen (CA)19-9 were found to be independent prognostic markers of disease progression within 12 months. Based on the Receiver Operating Characteristics (ROC) curve analysis, the patients could be divided into two groups: SUVmax≤4.1 vs. SUVmax>4.1. Patients with SUVmax values of 4.1 or less had significantly better progression-free survival within 12 months with an HR (95% CI) of 2.97 (1.4-6.3), relative to patients with SUVmax values above 4.1., Conclusion: SUVmax may be used as a novel prognostic marker of disease progression among patients with metastatic colorectal cancer. Values of SUVmax can be used to select patients with a more aggressive type of disease and higher risk for progression within 12 months of PET/CT analysis., (Copyright © 2020 by Academy of Sciences and Arts of Bosnia and Herzegovina.)
