The prevalence of prostatic malignancies, specifically in the Western world, continues to raise concerns [1]. This has constituted a healthcare burden as men in America face a one-in-seven lifetime risk of diagnosis [2][3]. Alarmingly, the incidence of prostate cancer has been globally reported among men with higher risks in developed countries compared to less developed countries [4][5]. The high mortality inherent in the disease has been obvious in all ethnic groups, but black men have the highest morbidity and mortality in the United States of America due to lack of access to quality care [2][6][7].

The widespread adoption of PSA screening has improved early detection, but a void remains in the process of identifying the best method to manage prostate malignancies [8][9]. Several factors such as ethnicity, educational level, and age have been noted to influence the choices men make, as evidenced by the overall preference of white men for surgery [10]. A significant survival difference between major treatment modalities of prostatic cancer has not been identified, and no proof exists to show that surgery reduces mortality [2][11]. The importance of alternative therapies has been gaining more attention as the emotional responses of individuals diagnosed with the disease cannot be underestimated in the decision-making process, considering the vital position of their partners [2][12]. The experiences of individuals diagnosed with the disease have not been well explored in many studies [13].

Many factors influence the options men take to manage their prostate cancer, but the optimal needs of all men include overall well-being, sexual, bowel, and urinary functions [2][3]. In the absence of any specific treatment options that stand out, the preferences and values of patients become very essential in the management of prostate cancer in men [14][15]. In a study, men reported sexual and urinary complications when radical prostatectomy and other methods of management were used [8], and several indications favored the use of AS [16]. With AS, the individual is afforded quality of life in areas important to them, such as sexual activity [17]. The overwhelming reports on the negative consequences of surgery made AS a preferred method of management in many men [18][19].

In localized prostate cancer still confined within the prostate gland, the concept of AS has become well accepted because of many positive benefits [6][8]. The process of active surveillance that comes with consumption of healthy diets with immune-boosting properties enables patients to postpone radical interventions with the negative consequences [7][8][20]. In view of several factors observed in the treatment of men diagnosed with prostate malignancies, this study summarizes existing evidence, identifies some gaps, and contributes towards safe and effective treatment options for the disease through systematic analysis.

The study aims to determine the effects treatment options have on patients with localized prostate cancer and identify factors that influence treatment options.

Specifically, this systematic analysis was guided by the following research questions:

Research question 1: What effects do active surveillance and radical prostatectomy have on patients with localized prostate cancer?

Research question 2: What factors influence localized prostate cancer treatment options?

Protocolandregistration

Registered with the International Prospective Register of Systematic Reviews (PROSPERO; registration number: CRD420261289313).

The researchers’ interest was to determine the effects that active surveillance and prostatectomy have on patients with localized prostate cancer and identify factors that influence treatment options. The review and report followed PRISMA guidelines [21], and all empirical evidence that met pre-specified eligibility criteria was included to answer the above research questions. The systematic reviews used in the study minimized bias and produced reliable findings that inform decision-making among authors [22]. Institutional Review Board of the University approved the study (IRB2026-10).

The health-related quality of life of men who received active surveillance and prostatectomy in terms of sexual, urinary, and bowel functions. The primary endpoint was the difference in health-related quality between active surveillance and prostatectomy from baseline at early and late time points.

The eligibility criteria of articles were determined by interactive processes among the authors who at first independently assessed them, followed by collective discussion before consensus was reached. All relevant data from all articles were succinctly reviewed and later discussed on ZOOM for solid agreement.

Statistical significance was demonstrated through the pooled results of analysis on both research questions #1 and #2. Table 3 shows the summary of meta-analysis on specific effects and factors.

Prostate cancer among men has become a global issue despite advancements in technology and evidence-based practices surrounding the healthcare industry. In view of many types of treatment modalities available, individuals diagnosed with the disease still find it difficult to make the best choice due to many factors such as age and overall health status. The overall health condition can be dependent on the level and characteristics of the malignancy, either localized or metastasized [35]. In many instances, young individuals with localized prostate cancer opted for surgery to preserve their sexual function, but aggressive surgery has many negative effects that often lead to regret [31].

Many men have started to see the use of active surveillance as an alternative option to avoid the negative consequences that surgery portends, because it allows ongoing observation and waiting until surgery is ultimately considered [16][29][36]. The provision of more information to healthcare providers and the public can sensitize more usage of active surveillance in view of the very low percentage of clinicians recommending the management option [28]. Individuals diagnosed with prostate cancer do have serious concerns about their sexual performance, and the use of AS has demonstrated efficacy in preserving the sexual functions of men [31]. In many studies, active surveillance has been identified as a viable and safe alternative to manage localized prostate cancer in the face of lack of superiority in surgical intervention [16][37]. In addition, surgical intervention does not decrease the mortality rate among diagnosed individuals, thereby necessitating the importance of taking essential steps to avoid unnecessary treatments that can be consequential [38].

Men who underwent active surveillance showed improved health qualities in areas of sexual and urinary functions than those who opted for radical prostatectomy [30][32][39], and negative outcomes were observed more in the case of prostatectomy [40]. In the adjusted urinary function and incontinence domains, radical prostatectomy scored significantly worse at all time points up to 5 years in comparison with active surveillance [41]. Although bowel complaints in prostate cancer are typically not symptoms of the cancer itself but are common side effects of treatment such as rectal bleeding after prostatectomy, exploration of alternate therapies can prevent post-treatment unwanted consequences [33][42].

The inclusion of studies on localized prostate cancer conducted across three countries and three regions comprising different ethnic groups, searched across five databases. Adding to the strength is the demographic characteristics of the participants in the pooled studies. [28]-[34]. A total of 2636 participants diagnosed with localized prostate cancer were included in the review. The study was limited to articles written in English, which was a limitation because articles in other languages might have contained valuable information, but interpretation could be a challenge for all authors.

This review proposes key areas for future research and practice. Future studies should explore factors that make the active surveillance option better than radical prostatectomy in the treatment of localized prostate cancer. The effectiveness of radical prostatectomy cannot be overemphasized in certain situations based on the grade of prostate cancer. However, opting for surgery in low-risk cancer may be due to other psychological components like fear of the unknown and lack of appropriate information. It has been noted that prostatectomy prevents further metastasis of cancerous cells, but it’s very important to explore other interventions based on the level of the malignancy. On the analysis of PSA level, four studies were not statistically significant, but the overall pooled effect of the studies was statistically significant with a p-value of 0.03, indicating that patients’ and practitioners’ awareness of PSA level plays a significant role in treatment choices. More studies required to explore what makes many urologists favor surgery instead of active surveillance in low-risk prostate cancer.

Regular PSA tests allow patients to avoid invasive treatments like surgery or radiation unless the cancer shows signs of progression. Perhaps low PSA levels can benefit more from non-invasive interventions. More studies may be required to determine the impact of nutrition and the use of complementary alternative therapies among various ethnic groups. The clinical stage of the disease also plays an important role, based on statistical significance with a p-value of 0.01. Both T1 and T2 are considered localized because they have not spread beyond the prostate capsule. Therefore, more studies need to be done on this in combination with PSA and Gleason scores to always determine the right interventions and prevent complications of low-risk prostate cancer. Age continues to be a factor in the treatment options, and it’s good to quantify the empirical benefits derived from surgery by patients in their 40’s and 50’s. Future studies can review the effectiveness of other interventions such as radiotherapy and chemotherapy.

It has been observed that radical prostatectomy negatively affects the sexual, urinary, and bowel functions of men more than other treatment options. However, most neurologists still prefer surgery over all other treatment options for localized prostate cancer. Making surgery a last resort will make other non-invasive interventions more acceptable in the management of low-risk prostate malignancy. In our studies, a few of the selected studies were not statistically significant, but the overall pool effects were statistically significant. The results validated the effects that treatment options like active surveillance and radical prostatectomy have on localized prostate cancer patients’ sexual, urinary, and bowel functions. From the results, we were able to discern factors that influence treatment options among men diagnosed with prostate malignancy.
