The Impact

Bladder cancer (BCa) is an endocrine-related tumour and the activation of androgen signalling pathways may promote bladder tumorigenesis. We summarized the available preclinical and clinical evidence on the implications of the manipulation of androgen signalling pathways on the outcomes of BCa therapies. A systematic review was performed in December 2020. We included papers that met the following criteria: original preclinical and clinical research; evaluating the impact of androgen signalling modulation on the outcomes of BCa therapies. Six preclinical and eight clinical studies were identified. The preclinical evidence demonstrates that the modulation of androgen receptor-related pathways has the potential to interfere with the activity of the Bacillus Calmette Guerin, doxorubicin, cisplatin, gemcitabine, and radiotherapy. The relative risk of BCa recurrence after transurethral resection of the bladder tumour (TURBT) is significantly lower in patients undergoing therapy with 5 alpha reductase inhibitors (5-ARIs) or androgen deprivation therapy (ADT) (Relative risk: 0.50, 95% CI: 0.30–0.82; p = 0.006). Subgroup analysis in patients receiving 5-ARIs revealed a relative risk of BCa recurrence of 0.46 (95% CI: 0.22–0.95; p = 0.040). A significant negative association between the ratio of T1 BCa patients in treated/control groups and the relative risk of BCa recurrence was observed. Therapy with 5-ARIs may represent a potential strategy aimed at reducing BCa recurrence rate, mainly in patients with low stage disease. Further studies are needed to confirm these preliminary data.

BACKGROUND: Sedentarism is an important modifiable risk factor in the struggle against cancer. In the last decades, the relationship between physical activity and different types of cancer has been investigated in depth. OBJECTIVE: To provide an overview of the literature on the effectiveness of physical activity in reducing the risk to develop bladder cancer and improving health-related quality of life in patients. METHODS: A systematic review was conducted through a search of the Embase, Cochrane, PubMed, Scopus, and Web of Science (WOS) databases to seek information and PRISMA system to delimitate the research. Outcomes included in searches were physical activity, tobacco consumption, obesity, body mass index, and metabolic syndrome, associated with bladder cancer and quality of life. RESULTS: Database searches identified 394 records, of which 75 were duplicated. A total of 280 articles were excluded based on abstract screening. An additional 16 full-text articles were excluded because they did not meet the eligibility criteria. Overall, 21 of the 23 studies included in the review reported beneficial effects of physical activity in bladder cancer. The majority of papers found that physical activity is a significant factor in reducing the risk of bladder cancer. Moreover, physical activity improves health-related quality of life in bladder cancer survivors, and diminishes both recurrence and mortality in those who engage in regular activity. Lastly, physical inactivity is associated with increased body mass index, obesity, metabolic syndrome, type 2 diabetes and unfavourable energy balance, which led to a greater probability of suffering from bladder cancer. CONCLUSIONS: These data reinforce the importance of promoting a healthy lifestyle to reduce the risk of bladder cancer and to improve survivorship and health-related quality of life of patients.
