Study Methods Results Conclusions Kim & Je (2014) Prostate cancer Gilbert et al (2011) Ovarian cancer Yin et al (2011) Non melanoma skin cancer Caini et al (2014) Selection criteria: Inclusion: original data from cohort/nested case-control studies of vitamin D intake or blood 25(OH)D concentrations; provided relative risks & confidence intervals. Exclusion: not reported. Outcome measure: Breast cancer incidence or mortality Selection criteria: Inclusion: primary epidemiological data & either: serum 25(OH)D or 1,25(OH) 2 D) concentrations or dietary and/or supplement vitamin D intake. 25(OH)D measured prior to cancer diagnosis. Exclusion: Animal or case studies. Chemotherapy also included. Studies on vit D & prostate cancer survival. Outcome measure: Prostate cancer Selection criteria: Inclusion: Original longitudinal human studies. Exclusion: Reviews, ecological & case control studies; only vitamin D intake reported; only ovarian cancer mortality assessed. Outcome measure Ovarian cancer incidence & mortality. Selection criteria: Inclusion: RCTs, case-control, nested case control, cohort studies examining association between vitamin D intake/ 25(OH)D concentration & cutaneous melanoma/non melanoma skin cancer risk which included measure of relative risk with 95% CI or another measure of statistical uncertainty & measure of tumour thickness. Exclusion: Ecological studies, case reports, reviews, editorials. Outcome measure Cutaneous melanoma & non melanoma skin cancer. Breast cancer risk (13 nested case control/1 cohort study; 9526 cases) 25(OH)D concentration (nmol/L): Highest (>77.4) vs lowest (72.6) vs lowest ( 72.6 vs < 52.4 nmol/L was significantly associated with better breast cancer survival. No association between 25(OH)D and total and aggressive prostate cancer risk. No significant association between 25(OH)D and ovarian cancer risk. No association between 25(OH)D & cutaneous melanoma risk. Higher 25(OH)D concentration associated with significant increase in basal cell skin cancer & non melanoma skin cancer risk. 219
