Abstract
Objetivos Aunque estudios recientes asocian la vitamina D con el cáncer de próstata, otros estudios descartan una asociación entre esta vitamina y el cáncer de próstata o el antígeno prostático específico (PSA). Dado que no se pueden extraer conclusiones de los datos existentes, realizamos un estudio para analizar la relación entre el PSA y la 25-hidroxivitamina D [25(OH)D]. Métodos Un total de 415 sujetos sin patologías prostáticas fueron seleccionados, y se clasificaron por edad y concentraciones de 25(OH)D. El análisis estadístico se realizó con la prueba de Shapiro-Wilk, la prueba t de Student, ANOVA, y el coeficiente de correlación de Pearson. Además, se calculó el tamaño mínimo de muestra requerido para obtener resultados estadísticamente significativos en función de la concentración de 25(OH)D. Así mismo, se realizó la prueba t de Student para muestras pareadas para analizar a los individuos con dos determinaciones de PSA espaciadas en el tiempo en los que las concentraciones de 25(OH)D aumentaron o disminuyeron más de un 25 %. Resultados Observamos una leve correlación entre la edad y el PSA (r=0,379, p<0,001). Sin embargo, al comparar la concentración de PSA entre grupos en función de 25(OH)D, no se hallaron diferencias significativas (p=0,891): 1,25±1,32 μg/L (grupo con 25(OH)D<50 nmol/L) y 1,17±0,90 (grupo con 25(OH)D≥50 nmol/L). El coeficiente de correlación de Pearson fue casi 0. El tamaño mínimo de la muestra necesario para obtener resultados estadísticamente significativos fue de 815.346 hombres. No observamos diferencias en las concentraciones de PSA en los individuos que se sometieron a dos determinaciones. Conclusiones Nuestros resultados muestran que no existe asociación entre los niveles de 25(OH)D y de PSA en hombres sin patologías prostáticas.

Association between serum 25-hydroxyvitamin D and prostate-specific antigen: a retrospective study in men without prostate pathology. ADVANCES IN LABORATORY MEDICINE 2023; 4:408-412.

Abstract
Objectives Recently, vitamin D status has been associated with prostate cancer risk. However, some studies argue that there is no association of vitamin D with prostate cancer risk and serum prostate-specific antigen (PSA) concentrations. No clear conclusions can be drawn from the studies found in the literature. Our aim was to assess the relationship between PSA and 25-hydroxyvitamin D [25(OH)D]. Methods We selected 415 individuals without prostate pathologies and subgroups were generated according to age and 25(OH)D. Statistical analyses were performed using Shapiro-Wilk test, Student's t and ANOVA tests, and Pearson's correlation. Besides, the minimum sample size needed to obtain statistically significant results between groups according to 25(OH)D concentration was calculated and a Student's t-test for paired samples was performed to study individuals with two PSA measurements over time, where 25(OH)D concentration increased or decreased more than 25 %. Results We observed a slight correlation between age and PSA concentration (r=0.379, p<0.001). However, we found no significant differences when we compared PSA concentrations between groups according to 25(OH)D concentrations (p=0.891): 1.25 ± 1.32 μg/L (group with 25(OH)D<50 nmol/L) and 1.17 ± 0.90 (group with 25(OH)D≥50 nmol/L). Pearson's correlation coefficient was close to 0. The minimum samples size to obtain statistically significant results was 815,346 men, and we observed no differences in PSA concentrations in individuals with two measurements. Conclusions Our findings show no association in men without prostate pathologies, based on 25(OH)D levels.

Vitamins as Possible Cancer Biomarkers: Significance and Limitations. Nutrients 2021; 13:nu13113914. [PMID: 34836171 PMCID: PMC8622959 DOI: 10.3390/nu13113914] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/21/2021] [Revised: 10/28/2021] [Accepted: 10/29/2021] [Indexed: 12/11/2022] Open
Abstract
The Western-style diet, which is common in developed countries and spreading into developing countries, is unbalanced in many respects. For instance, micronutrients (vitamins A, B complex, C, D, E, and K plus iron, zinc, selenium, and iodine) are generally depleted in Western food (causing what is known as ‘hidden hunger’), whereas some others (such as phosphorus) are added beyond the daily allowance. This imbalance in micronutrients can induce cellular damage that can increase the risk of cancer. Interestingly, there is a large body of evidence suggesting a strong correlation between vitamin intake as well as vitamin blood concentrations with the occurrence of certain types of cancer. The direction of association between the concentration of a given vitamin and cancer risk is tumor specific. The present review summarized the literature regarding vitamins and cancer risk to assess whether these could be used as diagnostic or prognostic markers, thus confirming their potential as biomarkers. Despite many studies that highlight the importance of monitoring vitamin blood or tissue concentrations in cancer patients and demonstrate the link between vitamin intake and cancer risk, there is still an urgent need for more data to assess the effectiveness of vitamins as biomarkers in the context of cancer. Therefore, this review aims to provide a solid basis to support further studies on this promising topic.

Abstract
PURPOSE We have aimed to determine whether oxidants-antioxidants play a role in the etiopathogenesis of bladder tumour by measuring their levels in the serums of patients with bladder tumour. MATERIAL METHOD Thirty patients with bladder tumour with superficial bladder tumour and 27 normal healthy volunteers were included in the study. Four cc of venous blood was taken from these patients and volunteers in the control group and centrifuged at 5000 rpm for 10 minutes and divided into serum and plasma. The activities of xanthine oxidase, glutathione reductase, glutathione-s transferase, reduced glutathione and superoxide dismutase enzymes in serum were then measured spectrophotometrically. FINDINGS Antioxidant parameters (glutathione-s-transferase, reduced glutathione, superoxide dismutase and glutathione reductase) in the serum of patients with bladder tumours were found statistically significantly lower than control group (p < .05). On the other hand, xanthine oxidase which is an oxidant indicator, was found significantly higher in patients with bladder cancer than control group (p < .05). CONCLUSION Oxidative stress is effective in the etiopathogenesis of bladder tumour. We, therefore, believe that antioxidants are protective against bladder tumours and will be effective in the treatment of bladder tumours.

Abstract
BACKGROUND AND AIM We examined the relationship among vit.D3, AMH, FT3, FT4, and TSH, in addition to the serum levels of reproductive hormones (FSH, LH, prolactin, and free testosterone), in oligoasthenoteratozoospermia and azoospermia patients in a cohort of infertile men from Egypt to establish a clinical marker/cause-effect relationship. METHODS This cross-sectional cohort study was carried out on 301 men (105 males with oligoasthenoteratozoospermia and 96 males with azoospermia), in addition to 100 controls. Measurements of serum vit.D3, AMH, FT3, FT4, and TSH levels, in addition to reproductive hormone assays, were performed on all included subjects, using ELISA kits. RESULTS Overall, results showed significantly lower serum levels of vit.D3 in infertile men than in the controls, with a greater decrease observed in men with azoospermia than in oligoasthenoteratozoospermia patients, (p < .05 for all). Significantly higher serum TSH and FSH levels and significantly lower serum free testosterone levels were observed in males with azoospermia than in males with oligoasthenoteratozoospermia and the controls (p < .05 for both). There were no significant differences between the studied groups in terms of AMH, FT3 or FT4 levels. LH levels were negatively correlated with TSH levels and positively correlated with AMH levels among men with oligoasthenoteratozoospermia, while among men with azoospermia, LH levels were positively correlated with vit.D3 levels (p < .05 for all). CONCLUSION Decreased Vit.D3 could play a role in male infertility, in addition to abnormal thyroid function, which needs further investigation.

Abstract
Introduction: Prostate cancer is the most common malignancy among men in the United States and the second most common cancer in Turkey. The incidence of prostate cancer is increasing in industrialized countries.Aim: The aim of the study was to assess the knowledge about prostate cancer, its diagnosis, and treatment among patients with lower urinary tract symptoms.Methods: This study was performed from January to April 2015 with the patients applied to our clinic. A questionnaire that includes 10 questions was administered to the participants.Results: One hundred fifty-nine participants were included in this study. The participants' ages were between 40 and 82 with a mean age of 61.5 ± 7.9 years. Patient awareness of prostate biopsy and prostate cancer were 21.37 and 71.06%. The main origin awareness of PSA testing is family and friends. On the other hand, if the doctor advises acout prostate biopsy, 47.16% of the patients would accept and 11.31% of them would refuse this invasive procedure.Conclusion: Prostate cancer is one of the important health-related problem among men in the world. Additional researches are needed to investigate the knowledge of prostate cancer among men and the Ministry of Health may take preventive methods to increase the cancer knowledge level of people.
