Daily activities and training experiences of urology residents during the coronavirus disease 2019 pandemic in Indonesia: A nationwide survey.

Objective: To explore the impact of the coronavirus disease 2019 (COVID-19) pandemic on the training experiences of urology residents in Indonesia. Methods: A cross-sectional study using a web-based questionnaire (SurveyMonkey) involved all registered urology residents in Indonesia. The questionnaire was structured in Bahasa Indonesia, composed of 28 questions, and divided into three sections: demographic characteristics, current daily activities, and opinions regarding training experiences during the COVID-19 outbreak. The survey was distributed to all respondents via chief of residents in each urology center from May 26, 2020 to Jun 2, 2020. Results: Of the total 247 registered urology residents, 243 were eligible for the study. The response and completeness rate for this study were 243/243 (100%). The median age of respondents was 30 (range: 24-38) years old, and 92.2% of them were male. Among them, 6 (2.5%) respondents were confirmed as COVID-19 positive. A decrease in residents' involvement in clinical and surgical activities was distinguishable in endourological and open procedures. Most educational activities were switched to web-based video conferences, while others opted for the in-person method. Smart learning methods, such as joining a national or international speaker webinar or watching a recorded video, were used by 93.8% and 80.7% of the respondents, respectively. The respondents thought that educational activities using web-based video conferences and smart learning methods were effective methods of learning. Overall, the respondents felt unsure whether training experiences during the COVID-19 pandemic were comparable to the respective period before. Conclusion: The COVID-19 pandemic negatively affected urology residents' training experiences. However, it also opened up new possibilities for incorporating new learning methodologies in the future.

Early upregulation of AR and steroidogenesis enzyme expression after 3 months of androgen-deprivation therapy.

BACKGROUND: Androgen deprivation therapy (ADT) is a standard treatment for advanced prostate cancer (PCa). However, PCa recurrence and progression rates during ADT are high. Until now, there has been no evidence regarding when progression begins. This study evaluated the gene expression of intraprostatic androgen receptor (AR) and steroidogenic enzymes in the early stages of ADT. METHODS: Prostate tissue samples were taken from PCa patients with urinary retention who received ADT (ADT-PCa; n = 10) and were further subgrouped into ADT ≤12 months (n = 4) and ADT > 12 months (n = 6). The ADT-PCa tissues were then compared with BPH (n = 12) and primary (no treatment) PCa tissues (n = 16). mRNA for gene expression analysis of AR and steroidogenic enzymes was extracted from formalin-fixed paraffin embedded (FFPE) tissues and analyzed by real-time PCR. Protein expression was evaluated by immunohistochemistry with specific antibodies. RESULTS: AR gene expression was higher in the ADT-PCa group than in the BPH or primary PCa group. Both the ADT ≤12 and > 12 months subgroups had significantly higher relative gene expression levels of AR (p < 0.01 and 0.03, respectively) than the primary PCa group. In the ADT-PCa group, AR protein expression showed an increasing trend in the ADT ≤12 months subgroup and was significantly elevated in the ADT > 12 months subgroup compared with the PCa group (100%; p < 0.01). Half (50%) of the patients in the ADT ≤12 months subgroup were found to have upregulation of AR, and one showed upregulation beginning at 3 months of ADT. A trend toward elevated relative gene expression of SRD5A3 was also apparent in the ADT groups. CONCLUSION: AR and steroidogenic enzymes are upregulated in ADT-PCa patients as early as 3 months, without PSA elevation. Steroidogenic enzymes, particularly SRD5A3, were also upregulated before PSA rose.

Blood Transfusions in Laparoscopic Living Donor Nephrectomy: Single Center Experience from 500 Cases.

INTRODUCTION: Laparoscopic surgery has been acknowledged to reduce the morbidity rate thus improving patient safety. During the LLDN, the most frequent complication is renal vessels injuries, which often requires a blood transfusion. Besides the need for a blood transfusion, major bleeding caused by renal vessels injuries requires open conversion and repair. Thus, this study would like to descript and analyze the need for blood transfusion in laparoscopic living donor nephrectomy surgery in our center. METHODS: We performed a retrospective cohort study in the Department of Urology at Cipto Mangunkusumo National Hospital. The records of all kidney transplantation donor patients who underwent LLDN procedures carried out at our institution from November 2011 to October 2017 were reviewed. Data including donor age, preoperative hemoglobin level, postoperative hemoglobin level, intraoperative bleeding, number of artery(ies), number of vein(s), donor side, conversion to open surgery, surgery duration, and donor BMI were collected and analyzed. These data were further correlated with the transfusion rate. RESULTS: There were 500 patients underwent laparoscopic living donor nephrectomy procedure at our institution. All of the patients had LLDN with a transperitoneal approach. The difference in blood transfusion rate proportion between male patients with 0.9% compared to 0.6% in female patients was not significant (p=0.782). There is no significant difference in blood transfusion rate proportion regarding renal side (p=0.494), number of artery (p=0.362), age (p=0.978), BMI (p=0.569), and preoperative hemoglobin (p=0.766). Median estimated blood loss in patients who received intraoperative blood transfusion was significantly much greater than in patients who did not receive a blood transfusion (p<0.001). CONCLUSION: Based on this study, we suggest that in our institution, preoperative blood products are not necessarily needed. The surgeon's learning curve and technique play a significant role in preventing intraoperative complications and blood loss.

Comparison of the Effects of Target-Controlled Infusion of Propofol and Sevoflurane as Maintenance of Anesthesia on Hemodynamic Profile in Kidney Transplantation.

BACKGROUND: Target-controlled infusion (TCI) propofol and sevoflurane are common agents for general anesthesia, including for kidney transplantation procedure. This study compared the effect of TCI propofol and sevoflurane on intraoperative hemodynamic profile in kidney transplant patients. METHODS: A single-blinded prospective study was performed in 46 kidney transplant recipients who were randomized into receiving TCI propofol or sevoflurane as anesthetics maintenance. Hemodynamic parameters such as mean arterial pressure (MAP), cardiac index (CI), stroke volume index (SVI), and systemic vascular resistance index (SVRI) were measured at baseline before induction, postintubation, first surgical incision, every 15 minutes after the first incision, reperfusion, and 15 minutes after reperfusion. Data were analyzed using unpaired t-test, paired t-test, and general linear model. RESULTS: Intraoperative MAP, CI, SVI, and SVRI changes were similar in both groups (p = 0.480, 0.216, 0.086, and 0.054). In comparison to the baseline value, TCI propofol and sevoflurane groups showed significant reductions of MAP at postintubation (p=0.010; p < 0.001) and during the first surgical incision (p=0.009; p < 0.001); significant reduction of CI at postintubation (p=0.003; p < 0.001) and during the first surgical incision (p < 0.001; p < 0.001); significant reduction of SVI at postintubation (p=0.013; p=0.008), during the first surgical incision (p=0.008; p=0.003), and 15 minutes after reperfusion (p=0.010; p=0.005); and significant increasing of SVRI during the first surgical incision (p=0.007; p=0.005). The TCI propofol group showed significantly lower SVRI compared to the sevoflurane group postintubation (p=0.029) and during the first surgical incision (p=0.026). CONCLUSION: Intraoperative hemodynamic profile was similar between the TCI propofol and sevoflurane group during kidney transplant surgery. The TCI propofol group had higher CI and SVI but showed significantly lower SVRI as compared to the sevoflurane group. The incidence of postanesthesia agitation, postoperative outcome, and complication were not significantly different between the two groups.

Effect of Pneumoperitoneum on Renal Resistive Index and Renal Function in Patients Who Have Undergone Laparoscopic Living Donor Nephrectomy: A Pilot Study.

INTRODUCTION: The use of low-pressure pneumoperitoneum during laparoscopic living donor nephrectomy (LLDN) was assumed to cause less renal damage compared to high-pressure pneumoperitoneum. This study aims to evaluate the effect of low vs high-pressure pneumoperitoneum during LLDN on renal function and renal resistive index (RRI), which has never been done before. MATERIALS AND METHODS: The subjects were divided into 2 groups, low-pressure (8-10 mmHg) and high-pressure pneumoperitoneum (12-14 mmHg). The RRI, serum creatinine, and estimated glomerular filtration rate were measured during the perioperative period. RESULTS: A total of 45 samples were analyzed in this study: 17 subjects in the low-pressure pneumoperitoneum group and 28 subjects in the high-pressure group. RRI levels remained within the normal range (< .80) with no significant difference observed between the 2 groups (P > .05) before surgery, intraoperatively, or post-surgery. The preoperative and postoperative serum creatinine and glomerular filtration rate were similar in both groups. CONCLUSIONS: The use of low-pressure pneumoperitoneum had no benefit compared to high-pressure pneumoperitoneum in preserving RRI and function in LLDN.

The importance of targeting intracrinology in prostate cancer management.

Accumulating evidence has shown that intracrinology in prostate cancer (PCa) has a pivotal role in survival of cancer cell. PCa cells are able to produce androgens from different androgen precursors, such as dehydroepiandrosterone, thereby maintaining androgen receptor signaling. Several drugs have been developed that target intracrinology, some of which are now being used as standard treatment for the so-called castrate-resistant prostate cancer (CRPC) patients. Recently, the US FDA approval has changed the indication of drugs targeting intracrinology, e.g., abiraterone and enzalutamide where it evolved from post-chemotherapy CRPC to hormone-naive metastatic PCa cases. This approval raises question whether those drugs can also be used as the first-line treatment in localized stage PCa cases. In addition, development of additional drugs targeting major components of intracrinology is ongoing. Application of these new drugs and administration of combinations of existing drugs will ultimately lead to an increase in the efficacy of such treatments as well as to reduce the toxicity of the therapy and to prevent the risk of resistance.

Survival analysis and development of a prognostic nomogram for bone-metastatic prostate cancer patients: A single-center experience in Indonesia.

OBJECTIVES: To analyze predictive clinical factors of survival in bone-metastatic prostate cancer, and to develop a prognostic nomogram for patients with this condition. METHODS: The present study included 392 patients with bone-metastatic prostate cancer treated with androgen deprivation therapy. Pretreatment parameters were analyzed using the Cox proportional hazards model to identify the predictors of overall survival. Covariates - which showed statistical significance on multivariate analysis - were used to develop a nomogram. A linear predictor model was utilized to develop the nomogram. RESULTS: The median overall survival was 40.3 months (95% confidence interval 32.2-48.5). Univariate analysis showed that clinical T stage, Gleason score, initial prostate-specific antigen value and the number of metastatic lesions were independent prognostic factors for overall survival. These predictors remained significant as independent prognostic factors for overall survival after analysis using the multivariate Cox regression model. The nomogram constructed from those prognostic factors showed good discrimination for predicting the 5-year overall survival, with an area under the curve of 0.69. Acceptable agreement of the observed and predicted probabilities was observed in the calibration plot. CONCLUSIONS: The present prognostic nomogram might be a useful tool for predicting overall survival in pretreatment bone-metastatic prostate cancer, specifically among Indonesian patients. Further studies are required to provide external validation to support the utilization of this nomogram.

Recent advances in optical imaging technologies for the detection of bladder cancer.

White-light cystoscopy (WLC) is the diagnostic standard for the detection of bladder cancer (BC). However, the detection of small papillary and subtle flat carcinoma in situ lesions is not always possible with WLC. Several adjunctive optical imaging technologies have been developed to improve BC detection and resection. Photodynamic diagnosis, which requires the administering of a photoactive substance, has a higher detection rate than WLC for the detection of BC. Narrow-band imaging provides better visualization of tumors by contrast enhancement between normal mucosa and well-vascularized lesions. A technology called confocal laser endomicroscopy can be used to obtain detailed images of tissue structure. Optical coherence tomography is a high-resolution imaging process that enables noninvasive, real-time, and high-quality tissue images. Several other optical imaging technologies are also being developed to assist with the detection of BC. In this review, we provide an overview of the strengths and weaknesses of these imaging technologies for the detection of BC.

Thrombus-like Tumor of Renal Cell Carcinoma Mimicking Transitional Cell Carcinoma of Kidney: A Case Report.

Renal cell carcinoma (RCC) is the most common malignancy of the kidney. It is not commonly form tumor thrombus in the ureter or renal pelvis. A 29-year-old woman presented with asymptomatic gross hematuria. Contrast CT study revealed a tumor suspected to be a Transitional Cell Carcinoma (TCC). However, tumor thrombus was found in the renal pelvis and ureter. We performed Nephroureterectomy, bladder cuff excision, and lymph node dissection, and the tumor was diagnosed histopathologically as RCC. We report a very rare case of thrombus-like tumor of renal cell carcinoma mimicking transitional cell carcinoma of kidney.

Surgical Management of Giant Genital Condyloma Acuminata by Using Double Keystone Flaps.

Condyloma acuminata in the external genitalia (genital warts) is a sexually transmitted disease that is often caused by human papillomavirus (HPV). We report a case of giant genital condyloma acuminata in a 35-year-old male patient with HIV comorbidity treated by wide surgical excision. Excision defect was covered with split thickness skin graft (STSG) and double keystone flaps. There was no complication after surgery. Ten months following surgery, there was no new condyloma lesion and the patient had normal voiding and erectile functions.

The Risk Factors of Prostate Cancer and Its Prevention: A Literature Review.

This is a literature review study. Data was obtained from several literature reviews and journal resources that have correlation with the risk factors involved in PCa including age, ethnicity, family history, insulin-Like growth factor, sexually transmitted disease, obesity, smoking, alcohol consumption, vasectomy, and diet, and the prevention of PCa including soy, lycopene, green tea, supplementation, and exercise.Numerous epidemiologic studies have linked PCa risk to various factors, i.e. age, ethnicity, family history, insulin like-growth factors, lifestyle, diet, environmental and occupational exposures. The results of epidemiological, In vivo, in vitro, and early clinical studies suggested that selected dietary products and supplementation may play a role in PCa prevention. More studies are still needed to explore and find the risk factors and preventive methods of PCa development. It is important for clinician to ellaborate these informations for education to lower PCa risks and prevent PCa.

Relationship of age, prostate-specific antigen, and prostate volume in Indonesian men with benign prostatic hyperplasia.

BACKGROUND: To investigate the relationship between age, prostate specific antigen (PSA), and prostate volume (PV) in Indonesian men with histologically proven benign prostatic hyperplasia. METHODS: Data were generated from our BPH database from June 1994 until December 2013. Subjects were men with a minimum age of 40 years with chief complaint of LUTS or urinary retention, diagnosed with BPH. All patients underwent TRUS-guided prostate biopsy. Patients with PSA level >10 ng/mL were excluded from the study to exclude the possibility of occult prostate cancer. PV was measured with TRUS. Appropriate statistical tests were employed for data analysis. RESULTS: In all, 1638 patients were enrolled in our study. There was a statistically significant difference in PSA (P = 0.03) and PV (P < 0.0001) between age groups. Overall correlation between age, PSA, and PV were: i). Age and PV (r = 0.12, P < 0.0001); ii). Age and PSA (r = 0.07, P = 0.008); iii). PSA and PV (r = 0.26, P < 0.0001). Subgroup analysis in terms of indwelling catheter use versus without: i). Age 66.09 ± 8 years versus 65.38 ± 7.66 years (P = 0.158); ii). PSA 4.93 ± 2.62 ng/mL versus 4.68 ± 2.82 ng/mL (P = 0.038); iii). PV 47.58 ± 21.33 mL versus 41.43 ± 20.55 mL (P < 0.0001). Correlation between age, PSA, and PV in patients were similar in patients with and without indwelling catheter. CONCLUSION: In Indonesian men with biopsy-proven BPH, both PV and PSA increased with ageing. Prostate volume was significantly correlated with PSA. Even though the results were weaker, these results are consistent with results in other sets of population. The results vary between different countries and thus, ethnicities. Indonesia is a populous a sociocultural and ethnically diverse country. Therefore, aside from PSA, age, and PV, when investigating men with BPH, ethnicity may also need to be taken into account.

Targeted Therapy for Metastatic Renal Cell Carcinoma.

In the past 10 years, recent development of targeted therapy in metastatic renal cell carcinoma (mRCC) has provided a new hope and significantly enhanced the prognosis of the disease. Three class of targeted therapy were developed, including multi-targeted tyrosine kinase inhibitors (TKI), the mammalian target of rapamycin (mTOR) complex-1 kinase inhibitors, and the humanized antivascular endothelial growth factor (VEGF) monoclonal antibody. Hence, the objective of this article was to critically examine the current evidence of targeted therapy treatment for patients with mRCC. In the majority of trials evaluating targeted therapy, patients were stratified according to Memorial Sloan Kattering Cancer Center (MSKCC) risk model and the recommendation of targeted treatment based on risk features. In first-line setting (no previous treatment), sunitinib, pazopanib, or bevacizumab plus IFN-α were recommended as treatment options for patient with favorable- or intermediate- risk features and clear cell histology. Patients who progressed after previous cytokine therapy would have sorafenib or axitinib as treatment options. Clear-cell mRCC with favorable- or intermediate- risk features and failure with first-line TKI therapy might be treated with sorafenib, everolimus, temsirolimus or axitinib. However, the current evidence did not show the best treatment sequencing after first-line TKI failure. In patients with poor-risk clear-cell and non-clear cell mRCC, temsirolimus was the treatment option supported by phase III clinical trial. In addition, several new drugs, nowadays, are still being investigated and waiting for the result of phase II or III clinical trial, and this might change the standard therapy for mRCC in the future.

Indonesian prostate cancer risk calculator (IPCRC): an application for predicting prostate cancer risk (a multicenter study).

AIM: to develop a prediction risk model of prostate cancer based on Indonesia population. METHODS: we included all benign prostate hyperthrophy (BPH) and PCa patients who had prostate biopsy and prostatectomy between January 2009 and December 2013 from 5 urology centers in Indonesia. The relationship between the possibility of PCa with the following variables including: age; PSA level, prostate volume (by transabdominal ultrasound or transrectal ultrasound) and digital rectal examination (DRE) finding. We calculated a predictive scoring equation to predict the possibility of PCa using chi-square analysis, Kolmogorov-Smirnov test, multiple logistic regression and ROC curve. Then, we designed an application for predicting prostate cancer risk called Indonesian Prostate Cancer Risk Calculator (IPCRC). RESULTS: there were 784 PCa and 1173 BPH patients were used for developing the risk calculator in our study. The mean ages, PSA and prostate volume are 66.9±8.1 years old; 72.4±248.9 ng/ml and 49.6±28.2 ml, respectively. Abnormal DRE was found in 637 PCa and 56 BPH. We included age, PSA level, abnormal DRE finding (all showed significant p<0.05 in univariate model). Additionally, although not significant, we included prostate volume (p=0.157) due to its clinical importance. The corrected ROC analysis showed AUC 0.935, sensitivity of 90.1% and specificity 80% in predicting the prostate cancer in our population. CONCLUSION: we have developed the Indonesian Prostate Cancer Risk Calculator which includes age, PSA, DRE, and prostate volume as its variables. Future prospective study to validate the risk calculator is needed.

Urologic cancer in Indonesia.

Non-communicable diseases, including cancer, start to become more common in Indonesia. According to the government statement, incidence of malignant diseases increased annually up to 8% in the last decade and these diseases become the seventh leading cause of death in Indonesia. On the basis of the latest Globocan report on cancer incidence in Indonesia, prostate cancer ranks sixth; followed by bladder (12th) and kidney (18th). More than half of patients with kidney cancer are diagnosed in the advanced stage. Besides renal cell carcinoma, there are significant number of people affected with squamous cell and transitional cell carcinoma because of kidney stones. Radical nephrectomy or cytoreductive nephrectomy was the primary treatment, mostly done as an open procedure. Transitional cell carcinoma is the commonest histology type in bladder cancer cases followed by squamous cell carcinoma, which almost always related to bladder stones. Unfortunately, >70% of our cases were diagnosed with muscle invasive bladder cancer, and ∼60% of these patients refused further radical treatment. Incidence of prostate cancer is increasing rapidly and it becomes the third most common cancer in men. However, most of our patients are diagnosed in the advanced stage. Radical prostatectomy or external beam radiotherapy is the treatment of choice in localized disease. Nearly 40% of the elderly patients are treated with primary androgen deprivation therapy. Therefore, it requires more research by the Indonesian urologists and other healthcare providers to diagnose these cancers in earlier stage as well as community education for prevention.

Safety of clean urologic operations without prophylaxis antibiotic therapy in Cipto Mangunkusumo Hospital, Jakarta: A double-blind randomized controlled trial study.

OBJECTIVE: This study was conducted to identify the safety measures of performing clean urologic operations without administration of prophylaxis antibiotics. METHODS: We conducted a double-blind randomized controlled trial with patients who underwent clean urologic operations in Cipto Mangunkusumo Hospital, Jakarta, Indonesia, from April 2013 to January 2014. The local and systemic infection states were compared between the prophylaxis and placebo groups. Local infection was identified as surgical site infection and systemic infection as fever and leukocytosis. RESULTS: A total of 42 patients participated in the study (21 patients in each group), comprising 14 (33.3%) children and 28 (66.7%) adults. The most frequently performed operation was surgical sperm retrieval. No patients in either group were found to have local or systemic infection. However, there was a statistical difference in the white blood cell counts between the two groups (p = 0.003), although there was no sign of local or systemic infection in any of the patients. CONCLUSION: Clean urologic operations without prophylaxis antibiotic therapy can be safely applied to urologic patients.

Prevalence of urinary incontinence, risk factors and its impact: multivariate analysis from Indonesian nationwide survey.

AIM: to describe the profile of urinary infection (UI) and to analyze its risk factors and impacts. METHODS: subjects were enrolled consecutively from pediatric, urology, obstetrics and gynecology, and geriatric outpatient clinics at six teaching hospitals in various regions of Indonesia. Those with urinary tract infection and diabetes mellitus were excluded. The UI questionnaire was adapted from the 3 Incontinence Questions (3IQ). Written informed consent was obtained prior to the interview. RESULTS: about 2765 completed questionnaires were obtained. The overall UI prevalence was 13.0%, which consisted of prevalence of stress UI (4.0%), urgency UI/wet OAB (4.1%), dry OAB (1.6%), mixed UI (1.6%), overflow UI (0.4%), enuresis (0.4%), other UI (0.7%). The prevalence of UI was significantly higher (p<0.001) in geriatric population (22.2%) compared to the adult (12.0%), and pediatric population (6.8%). There was no prevalence difference (p>0.05) between male and female subjects. Enuresis and urgency UI/wet OAB were the most common UI in pediatric population. The prevalence was 2.3% and 2.1% respectively. Urgency UI and stress UI were the two most common type in adult and geriatric population. Both have an equal prevalence of 4.6%. The multivariate analysis showed that the prevalence of UI increased with LUTS (PR 4.22, 95%CI 2.98-5.97), chronic cough (PR 2.08, 95% CI 1.32-3.28), and fecal incontinence (PR 1.85, 95% CI 1.03-3.32). We found that UI impaired family life (25.3%), sexual relationship (13.6%), and job/school performance (23.7%). Frequent toilet use and reducing fluid intake were the two most common behavior changes. CONCLUSION: the prevalence of UI in Indonesia is nearly similar to other Asian countries. It increases with age and is not affected by gender. LUTS, chronic cough, and fecal incontinence may have significant effects on the prevalence. UI seems to impact daily life and behavior.

Effective dose and adverse effects of maintenance Bacillus Calmette-Gue'Rin in intermediate and high risk non-muscle invasive bladder cancer: a meta-analysis of randomized clinical trial.

AIM: To evaluate the effective dose and adverse effects of BCG doses. METHODS: We searched published RCTs in Medline and Cochrane database before October 2013. Article using maintenance BCG after TUR in intermediate-high risk non-muscle invasive bladder cancer (NMIBC) and followed for effectiveness, local and systemic side effect are included. Low risk patients, other dose and MIBC were excluded. RESULTS: Meta-analysis of 6 clinical trials involving 2719 intermediate-high risk NMIBC patients showed recurrence rate in full dose (81 mg), low dose (27 mg) and very low dose (13.5 mg) were 33.3%, 34.7% and 30%, respectively. Meta-analysis of 2175 patients, 81 mg BCG was found to be superior to 27 mg in reducing tumour recurrences (RR 0.86; 95% CI 0.77-0.96, I2=0% and p=0.008). Meta-analysis of 544 patients, the effectiveness reducing tumour recurrences in 27 mg BCG was found to be superior to 13,5 BCG (RR 0.66; 95% CI 0.49-0.89, I2=8.8% and p=0.006). Systemic side effects were happened in 25%, 28.5%, and 15.5% in the doses 81.27 and 13.5 mg BCG, respectively. Low dose was superior to full dose in affecting systemic side effect (p=0,000) but no difference in affecting local side effect (p=0.137) in the meta-analysis of 1816 patients in 2 clinical trials. CONCLUSION: Full dose BCG had superior outcome to reduce recurrences compared to low dose and very low dose. There were no significant differences between each dose in local side effect. However full dose regimen has higher systemic side effect compared to low and very low dose.

Prostate cancer in younger and older patients: do we treat them differently?

Diagnostic and therapeutic strategies of prostate cancer may largely influenced by patients' age at presentation. This study is aimed to evaluate the characteristics, diagnostic and treatment strategies in prostate cancer patients in our centres. A cross-sectional analytic study of prostate cancer data in two main referral cancer centres, Cipto Mangunkusumo General Hospital and Dharmais National Cancer Centre from 1995-2010, was therefore performed. Patients were divided into 2 sub-populations; below 60 years (younger patients) and 75 years old and above (older patients). PSA levels, diagnostic modalities, Gleason score and therapeutic options were analysed for both and compared using bivariate analysis. 152 patients were <60 years and 210 were ≥75 years. There was no statistical difference in mean PSA level (797.9ng/mL vs 345.3 ng/mL, respectively; p>0.05) and diagnosis was made by biopsy in majority of patients in both groups (68.2% and 71.6% in younger and older groups respectively). Most presented with an advanced disease stage (65.1% and 66.0%, respectively) and there was no statistically significant difference in mean Gleason scores f (8.1 vs 7.7; p>0.05). Primary androgen deprivation therapy (PADT) was the main treatment for overall patients (48.0% and 50.7%, respectively). Radiotherapy and radical prostatectomy are the main therapeutic modalities for younger patients with local and locally advanced disease (39.6% and 35.4% respectively), while the majority of older patients with the same disease stage were treated with radiotherapy and PADT (45.8% and 39.0% respectively). Differences observed in treatment modalities were statistically significant (p<0.0003). We conclude that there is no difference in disease clinical aggressiveness of the two groups but significant differences were obseved in therapeutic strategies utilised with younger and older patients.
