“…General characteristics of case-control and cohort studies are shown in Tables 1 and 2, respectively. Case-control studies were published between 1994 and 2014; three were conducted in Italy (13,19,22) , two each in Iran (10,15) , China (12,23) and Australia (14,29) , and one each in Poland (16) , Spain (11) , Czech Republic (17) , Brazil (18) , UK (20) , India (24) , Hawaii (25) , Mexico (26) , Sweden (27) and Uruguay (28) . One was a multinational study conducted in nine countries worldwide (Italy, Spain, Poland, Northern Ireland, India, Cuba, Canada, Australia and Sudan) (21) Cohort studies were published between 1998 and 2012; nine were conducted in the USA (30,31,(34)(35)(36)(37)39,40,45) and eight were conducted in Europe (32,33,38,(41)(42)(43)(44)46) .…”

Objective: Conflicting results on the association between fruit consumption and cancer risk have been reported. Little is known about the cancer preventive effects of different fruit types. The present meta-analysis investigates whether an association exists between apple intake and cancer risk. Design: Relevant observational studies were identified by literature search (PubMed, Web of Science and Embase). A random-effect model was used to estimate the cancer risk in different anatomical sites. Between-study heterogeneity and publication bias were assessed using adequate statistical tests. Results: Twenty case-control (three on lung, five on colorectal, five on breast, two on oesophageal, three on oral cavity, two on prostate and one each on pancreas, bladder, larynx, ovary, kidney and brain cancer) and twenty-one cohort (seven on lung, two on colorectal, three on breast and one each on oesophageal, pancreas, bladder, kidney, endometrial, head-neck, urothelial and stomach cancer) studies met the inclusion criteria. Comparing the highest v. lowest level of apple consumption, the reduction of lung cancer risk was statistically highly significant in both case-control (OR = 0·75; 95 % CI 0·63, 0·88; P = 0·001, I 2 = 0 %) and cohort studies (relative risk = 0·89; 95 % CI 0·84, 0·94; P < 0·001, I 2 = 53 %). Instead, in the case of colorectal (OR = 0·66; 95 % CI 0·54, 0·81; P < 0·001, I 2 = 55 %), breast (OR = 0·79; 95 % CI 0·73, 0·87; P < 0·001, I 2 = 1 %) and overall digestive tract (OR = 0·50; 95 % CI 0·36, 0·69; P < 0·001, I 2 = 90 %) cancers a significant preventive effect of apples was found only in case-control studies while prospective studies indicated no effect. No evidence of publication bias could be detected for colorectal, oral cavity, oesophageal and breast cancer. However, some confounding effects may be present and related to the consumption of other fruit which have not been considered as adjusting factors. Conclusions: The present meta-analysis indicates that consumption of apples is associated with a reduced risk of cancer in different anatomical sites. Keywords Cancer preventionApple intake Dietary Epidemiology Meta-analysis Cancer is a chronic degenerative disease causing major morbidity and mortality in Western countries. It has been estimated that in the year 2012, 14·1 million new cancer cases were diagnosed and 8·2 million cancer deaths were established (1) . The overall age-standardized cancer incidence rates vary three-to fivefold across different regions of the world (2) . These variations may be related to different modifiable risk and preventive factors among which diet may play a central role. It has been estimated that about one-third of all cancer could be avoidable by changes in eating habits (3) .Foods of plant origin have received particular interest over the years as potential cancer-preventive components of a healthy diet. Fruit and vegetables contain a myriad of bioactive phytochemicals that, through various molecular mechanisms, show chemopreventive properties in both in...

“…Some studies reported that radiation, tobacco, alcohol, head trauma, exposure of N-nitroso compounds were risk factors (Giles et al, 1994;Inskip et al, 1998;Braganza et al, 2012). Additionally, some studies found an increased incidence of brain cancer among white collar professionals, electrical, oil refinery and agriculture workers (Savitz and Loomis, 1995;Musicco et al, 1988;Preston-Martin, 1998).…”

Background: The prognosis of primary glioblastoma (GBM) is poor. Approximately 2/3 of primary brain tumor diagnoses are GBM, of which 95% are primary lesions. In this study, we aimed to evaluate whether more sunlight exposure has an effect on survival of patients with primary GBM. Materials and Methods: A total of 111 patients with primary GBM were enrolled from Kayseri in inner Anatolia which has a cold climate (n: 40) and Mersin in Mediterranean region with a warm climate and more sunlight exposure (n: 71). The patients with primary GBM were divided into two groups as Kayseri and Mersin and compared for progression free survival (PFS) and overall survival (OS).Results: The PFS values were 7.0 and 4.7 months for Kayseri and Mersin groups, respectively (p=0.10) and the repsective OS values were 13.3 and 9.4 months (p=0.13). We did not found any significant difference regarding age, sex, comorbidity, smoking, surgery, resurgery, adjuvant chemoradiotherapy and palliative chemotherapy between the groups. Conclusions: We found that more sunlight exposure had no impact on prognosis of patients with primary GBM, adding inconsistency to the literature about the relationship between sunlight and GBM.
