Introduction: Prostate cancer is recognized as the leading cause of malignancy-related incidence and mortality in the male population. The treatment regimens have long-term effects detrimental to the patient's quality of life. Hence, this review was aimed to determine the overall HRQOL and its associated among prostate cancer patients.
Methods: The review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. The databases searched were PubMed, Embase, Google Scholar and Cumulative Index to the Nursing and Allied Literature (CINAHL), which provided articles that were critically examined, yielding 52 studies that met the inclusion criteria for the systematic review.
Results: Out of 52 studies, 30 studies reported poor overall HRQOL in various domains after prostate cancer treatment. Contrastingly, 15 studies reported good overall quality of life after treatment. Among the various domains, sexual function was the most grossly affected functional score by the treatment modalities of prostate cancer. Nonetheless, seven studies showed that the absence of a significant change in the overall quality of life after treatment. According to the studies, older age, comorbidities, higher clinical stage, higher Gleason score, greater cancer severity, African American race, impaired mental health, neoadjuvant hormonal therapy and lower level of education were the major poor predictors of HRQOL among prostate cancer patients.
Conclusion: The overall HRQOL in prostate cancer patients was generally poor in various functional domains after treatment. Among the various domains, sexual function was the most grossly affected functional score by the treatment modalities of prostate cancer.
