Introduction

The incidence of PCa is expected to double in Asia in the next two decades, and the disease bur­den will further increase as a result. According to the “Lancet Commission on Prostate Cancer: Planning for the surge in cases,” changing age structure and longer life expectancy are driving the surge of PCa, from 1.4 million new cases in 2020 to 2.9 million in 2040 [1].
The majority of screening-detected prostate can­cers are low-grade and low-stage, rendering them suitable for active surveillance in the low- risk group and potentially for focal therapy in the intermediate­risk group with low-volume cancers. While the epi­demiology of PCa and healthcare accessibility vary signicantly between Asian countries, the aware­ness of PCa is rising in general. Cultural differences in decision-making and the acceptance of gland­preserving strategies, as well as geographic vari-

ability in the dissemination of advanced imaging, biopsy, and ablative technologies, are also signi­cant factors in the uptake of focal therapy and active surveillance in East and Southeast Asia.
For favorable risk localized PCa, disease pro­gression is in general slow, and it has been shown in the latest PROTECT trial data (including the majority ISUP group 1 PCa) that only 50% of patients at 10years and 60% at 15years required a switch to treatment from active monitoring. (reference) Immediate radical treatment with prostatectomy or radiotherapy is therefore an overtreatment with signicant morbidities. The latest European and American guidelines strongly suggest AS as the management of choice for men with low- or favorable-risk PCa.
Focal therapy (FT) is a middle ground between AS and radical treatment. It is increasingly used as an active surveillance “extender” by eradi­cating foci of clinically signicant cancer so that the patient may go back on surveillance for clini­cally insignicant cancers. This aims to reduce the harms of over-diagnosis and over-treatment, which are common barriers to PCa screening.
The FT strategy is highly relevant in regions with a higher degree of PCa screening or early detection, in which more localized disease is diagnosed. In regions with a lower degree of PSA testing, the diagnosed cancers are generally of higher grade or stage and may not be the ideal candidates for FT.Careful case selection is essen­tial to ensure the success of FT.

Current literature on AS and FT in Asia remains limited. With longer life expectancy and increasing awareness of early cancer detection, we believe FT and AS will become increasingly important in the management of PCa in Asia. In this chapter, we focus on the demographics of PCa in Asia and the practices of AS and FT in East and Southeast Asia.
Prostate Cancer Incidence andMortality
The Globocan 2020 estimate for world prostate cancer new cases was 1,414,259 with new deaths of 375,304 [2, 3]. In developed areas, the inci­dence rate was 37.5 per 100,000 with a mortality rate of 8.1 per 100,000 leading to a ratio of mor­tality to incidence at 21.6%. In contrast, in less developed areas, the ratio of mortality to inci­dence was 52%. This may be attributed to less PSA testing in less developed areas, resulting in the detection of symptomatic and advanced PCa.
In general, a rise in the incidence of prostate cancer has been observed in East and Southeast Asia over the last few decades [4, 5]. While the highest incidence was found in high-income countries, the highest mortality was observed in low-income countries [6].
In an updated review by Ito and Kimura in 2023, Asian men have a wide variation in terms of age-standardized rates of incidence and mor­tality [7]. Among East and Southeast Asian coun­tries, per 100,000 men, Japan has the highest incidence rates, followed by Singapore, South Korea, and the Philippines. The mortality-to­incidence ratios, a measure of long-term cancer surveillance and treatment programs, were higher in developing countries like North Korea, Bangladesh, Cambodia, India, Philippines, and China and lower in developed countries like Japan, South Korea, and Singapore [7]. Environmental factors or Westernization of diets resulting in obesity and the gradual loss of “cul­tural protective factors” may be explanations for the above [8]. The observation that Asian immi­grants to Western countries have shown PCa rates closer to the Western countries provides another
evidence to support this theory [9, 10]. The mor­tality in a number of developed countries like Japan, South Korea, and Singapore has reduced or plateaued off in the last 20years, and this is likely related to increased PSA screening, earlier diagnosis, and improved treatment for advanced PCa [7].
Prostate Cancer Screening andDetection
PSA screening is more encouraged in certain regions in East and Southeast Asia, like Japan, but opportunistic or in response to symptoms in most. There is no formal screening program in most regions. This difference can be easily cor­related with metastatic disease at presentation. In Malaysia, 58.1% of newly diagnosed PCa were diagnosed at the M1 stage [11]. On the other hand, M1 disease in Japan reduced from 24.2% in the 1990s to 12.4% in 2010–2014 after the introduction of PSA screening [12].
In various Asian biopsy cohorts reported in South Korea, Japan, Singapore, Hong Kong, and Malaysia, the PCa detection rate using systematic biopsy for PSA 4–10ng/ml ranged from 15% to 25%, and that for PSA 10–20ng/ml ranged from 35% to 60% [1319]. These series represent areas with a higher degree of PSA testing com­pared to the rest of Asia, and more low-grade PCa were diagnosed. In a Taiwan study including more than 8000 men, an increase in low-grade PCa from 17% to 41% was observed over a 10-year period with the increase in PSA testing [20].
Status ofActive Surveillance inEast andSoutheast Asia
Contrary to the practice in the Western world, where AS is the recommended form of manage­ment of low- and favorable-risk PCa, the use of AS in Asia is much less common. According to the report of the Asian Prostate Cancer (A-CAP) study involving a large proportion of Asian coun­tries, the use of AS in Asia has been very uncom-

mon, and this is a common observation in Asia, including China, South Korea, and Japan, where most patients demand some form of treatment for their localized PCa and refuse to be put on sur­veillance [21]. In China, it is a common phenom­enon that a patient with low-risk PCa who was offered AS in one hospital will seek treatment in another hospital within a few days.
In Japan, the use of ASis relatively higher in academic centers and centers that participated in international AS studies (e.g., PRIAS, Prostate Cancer Research International Active Surveillance) [22]. The reluctance of Asian patients to agree to repeated biopsies and poor long-term compliance to repeated biopsies in AS protocol are other reasons that reduce patients’ incentive to agree to AS. The Japanese PRIAS cohort, who were managed mainly by academic centers, reported biopsy compliance of 83% at 1 year, 64% at 4 years, and 39% at 7 years. Biopsy compliance in nonacademic centers and in less developed countries is expected to be much lower. Poor adherence to the AS protocol may result in delayed diagnosis of disease pro­gression, loss-to-follow-up, and possibly meta­static disease and loss of window of cure. As shown in the Active monitoring arm in the PROTECT trial, a lack of a stringent AS protocol may result in a higher rate of M1 disease in the long run [23]. Patients living in rural areas in China being diagnosed in urban hospitals may not return for follow-up in the long run, and therefore, a biopsy followed by a prostatectomy within a few days may offer the best cure in one hospital attendance.
The mode of PCa diagnosis may also limit the condence of urologists in offering AS, espe­cially in centers where prostate biopsies may not be performed under MRI guidance. The risks of under-grading and under-staging of the disease may pose a risk of delayed treatment in men offered AS.A study in India demonstrated about half of low-risk prostatectomy cases had upgrad­ing at nal pathology, and therefore, the mode and precision of PCa diagnosis can affect the condence in offering AS to patients [24].
Another barrier to physicians’ choice of AS vs radical treatment is the reimbursement pattern. In
Asian countries where urologists and hospitals are compensated by the number of surgeries or treatment sessions being performed, there is a low incentive to offer AS to patients.
Status ofFocal Therapy inEast/ South-East Asia
Focal therapy is not common in Asia, and most centers do not have this option. However, a few academic centers in Asia have started FT more than a decade ago, and FT is expected to gain interest as another treatment alternative [25]. Chen and Chiang etal. reported 182 whole-gland HIFU performed in Kaohsiung, Taiwan, from 2009 to 2015, reporting a biochemical recurrence rate of 27% at a median of 32months [26]. Whole gland cryotherapy has been performed by Pu and Chen etal. since 2008in Taiwan. The rst report included 192 patients from 2010 to 2012, and long-term follow-up at a median of 81months showed that 37% had a biochemical recurrence, and the anterior apical location was a strong pre­dictor of recurrence [27]. The same group by Chen and Pu et al. also reported on a selected group of high-risk PCa patients treated with whole gland cryotherapy and reported 10-year biochemical recurrence-free survival at 1, 3, 5, and 10 years were 93%, 77%, 67%, and 51%, respectively, and cancer-specic survival was
97.4% at 10years [28]. Tan etal. reported on 28 men with clinically signicant prostate cancer treated with focal cryotherapy in a Singapore Phase II trial and reported 21.4% signicant can­cer (7.1% ineld, 10.7% outeld, and 3.6% in­and outeld) at 1-year per-protocol targeted and saturation biopsy [29]. Further analysis by the group reported that mpMRI using PIRADS v2.1 had a high sensitivity and negative predictive value in detecting clinically signicant recur­rences [30].
Shoji etal. demonstrated excellent functional outcomes after HIFU in PCa patients, with uri­nary and erectile functions returning to baseline functions within a few months after HIFU [31]. They also reported oncological outcomes of 428 patients in Japan who received whole-gland
82
P. K.-F. Chiu et al.
HIFU, and biochemical recurrence-free rates at a median of 5 years were shown to be 80.4%,
65.6%, and 61.6% in low, intermediate-, and high-risk patients, respectively [32]. Shoji also demonstrated that the compression technique and neoadjuvant hormonal therapy (in high-risk PCa) were two independent predictors of biochemical failure [32]. The series of HIFU studies in Japan has led to the approval of HIFU in Japan under advanced medical care, and patients are partially reimbursed.
Irreversible electroporation (IRE) was per­formed by Lee JY etal. in South Korea, and in 17 patients diagnosed with PET and MRI prostate, 88% of patients achieved negative biopsy at 12 months [33]. Second-generation high­frequency IRE (H-FIRE) was performed by Wang etal. in Shanghai, China, and reported the early ndings in JAMA Surgery in 2022. In 109 patients who received H-FIRE, 94% of patients had no signicant PCa rate at 6-month per­protocol biopsy [34].
Targeted microwave ablation (TMA) with transperineal MRI-ultrasound fusion guidance using organ-based tracking was performed by Chiu et al. in Hong Kong, and the initial out­comes of 15 men showed that 91% of ablated areas showed no cancer at 6-month biopsy [35]. A review by Fujihara and Ukimura etal. reported 94–100% pad-free continence and 47–86% erec­tile function sufcient for penetrative sex after focal therapy, and about 10–30% required con­ventional whole gland radical treatment [36]. Kunogi etal. used a novel low-dose-rate brachy­therapy for low-to-intermediate risk prostate can­cer, and the efcacy and feasibility turned out to be acceptable [37].
plethora of methods, such as multi-parametric magnetic resonance imaging (mpMRI), advanced biopsy techniques (mapping or saturation pros­tate biopsies), and genomic markers that are available to aid in the stratication of patients to gland-conserving strategies or radical interven­tions [43]. The use of multiparametric MRI pros­tate is getting more and more common in Asia to guide biopsy decisions and facilitate targeted biopsy. Fujii etal. reported on the effectiveness of mpMRI in nding more signicant prostate cancer in biopsy-naïve men [44]. Deep-learning methods were utilized by Matsuoka etal. for the detection and segmentation of prostate cancer [45].
Biomarkers have been used to improve the detection of high-grade PCa in patients with MRI prostates performed. Shoji etal. evaluated a novel blood test called LacdiNAc-glycosylated­prostate specic antigen (LDH-PSA), and in combination with prostate volume, created LDH­PSA density (LDH-PSAD), which can identify high-grade cancer in men with PI-RADS 3 dis­ease [46]. In a PCa screening study performed in Hong Kong, Chiu etal. reported that adding MRI prostate to the combined strategy of PSA and prostate health index blood tests for prostate can­cer screening appears to effectively diagnose clinically signicant prostate cancer while limit­ing unnecessary biopsies in men with PSA
4.0–10.0 ng/ml [47]. Transperineal mapping biopsy by Lee etal. in Singapore demonstrated a novel intensive sampling of the umbra and pen­umbra, which improved the detection of clini­cally signicant prostate and reduced the risk of upgrading at radical prostatectomy [48].
Patient Selection forActive Surveillance andFocal Therapy
Patient selection is crucial in identifying suitable patients for AS and FT [38]. It is well known that standard 12-core Transrectal prostate biopsy under-grades 30–50% of PCa [39]. Similar nd­ings have been observed in series from Korea, Japan, and Singapore [4042]. There now exists a
Shared Decision-Making inAsia
Focal therapy and active surveillance for prostate cancer is a relatively novel concept. With the numerous treatment options available, decision­making in prostate cancer has become compli­cated, and shared-decision-making is important. To further complicate matters, decision-making in an Asian context tends to take on cultural hues. A focused group discussion of Malaysian urolo-

gists exploring decision-making roles in local­ized prostate cancer treatment showed that many healthcare providers still preferred a more pater­nalistic role [49]. In a multicultural, multiracial survey conducted among patients in Singapore, two-thirds of patients, if diagnosed with cancer, would want their family to participate in decision­making [50]. (Rhunke etal.) Japanese value the role of the family and doctor’s recommendations more than individual decision-making, while the reverse is true in the United States [51]. Urologists in Asia need to balance cultural traditions and generational changes to help guide the patient to the most appropriate treatment choice.

Conclusions

Active surveillance is suitable for ISUP grade group 1 and selected grade group 2 prostate can­cers. Focal therapy is a middle ground between AS and radical treatment and is an alternative for more aggressive but low-volume focal prostate cancer while minimizing treatment morbidities. Both AS and FT strategies are more applicable in a setting where there are higher rates of focal low- to intermediate-risk PCa diagnosis. Early detection of PCa is gaining attention in Asia, and more countries are gradually adopting PSA as a tool for early detection. There is a need for prop­erly conducted AS and FT to reduce the harms of PCa screening and over-treatment. These treat­ment strategies will need to be supported by the increasing adoption of advanced MRI imaging, MRI-guided biopsy techniques, and ablative technologies, as well as trained urologists and radiologists.
