CD44 and CD133 protein expression might serve as a prognostic factor for early occurrence castration-resistant prostate cancer.

BACKGROUND: The occurrence of castration-resistant prostate cancer (CRPC) varies in patients with advanced prostate cancer (PCa) undergoing androgen deprivation therapy (ADT). The rate of occurrence of CRPC may be related to the presence of prostate cancer stem cells (CSC). Thus, this study aims to evaluate the presence of CSC markers (CD44 and CD133) in histopathology tissue at the time of diagnosis and their correlation with the occurrence of CRPC in patients with advanced PCa within 2 years of ADT. METHOD: A retrospective case-control study was conducted to evaluate the incidence of CRPC within 2 years. The inclusion criteria were patients with PCa who had received treatment with ADT and a first-generation anti-androgen (AA) for 2 years. We classified patients based on whether they developed CRPC within 2 years (CRPC) of the therapy or did not experience CRPC within 2 years (non-CRPC) of the therapy. We performed immunohistochemical (IHC) staining for CD44 and CD133 on the prostate biopsy tissue samples. RESULTS: Data were collected from records spanning 2011-2019. We analyzed a total of 65 samples, including 22 patients with CRPC and 43 patients with non-CRPC who had received treatment with LHRH agonists and AA for up to 2 years. Our findings showed a significant H-score difference in CD44 protein expression between CRPC prostate adenocarcinoma samples 869 (200-1329) and non-CRPC 524 (154-1166) (p = 0.033). There was no significant difference in CD133 protein expression between the two groups (p = 0.554). However, there was a significant difference in the nonoccurrence of CRPC between the high expressions of both CD44 and CD133 groups with other expressions of CD44/CD133 groups (25% vs. 75%; p = 0.011; odds ratio = 4.29; 95% confidence interval [1.34, 13.76]). CONCLUSION: This study found a low expression of at least one CD44/CD133 protein in the patients without early occurrence of CRPC. This result might suggest that CD44/CD133 may function as a potential prognostic marker for PCa, especially in a low expression, to identify patients who have a better prognosis regarding the occurrence of early CRPC.

Renal cell carcinoma not otherwise specified: A case report in Indonesia.

Renal cell carcinoma not otherwise specified (RCC NOS) is a very rare type of kidney cancer which used for renal tumors that do not fit into any of the well-recognized subtypes. We reported a case of RCC NOS of a 64-year-old male presenting an enlarging left flank mass. Abdominal CT showed a left kidney mass infiltrating to the adrenal, with pulmonary metastases. Cytoreductive nephrectomy and lymphadenectomy were performed and diagnosis of RCC NOS was confirmed through histopatological and immunohistochemistry examination.

The expression of stem cells markers and its effects on the propensity for recurrence and metastasis in bladder cancer: A systematic review.

Bladder cancer is one of the most frequent cancers of the urinary tract, associated with high recurrence rates and metastasis. Cancer stem cells (CSCs) are a subpopulation of cancer cells characterized by high self-renewal and differentiation capacities, resulting in increased cancer recurrence, larger tumor size, higher rates of metastasis, higher resistance to treatment, and overall poorer prognosis. This study aimed to evaluate the role of CSCs as a prognostic tool to predict the risks of metastasis and recurrence in bladder cancer. A literature search was conducted across seven databases from January 2000 to February 2022 for clinical studies investigating the use of CSCs to determine the prognosis of bladder cancer. The following keywords were used: ("Bladder Cancer" OR "Transitional Cell Carcinoma" OR "Urothelial Carcinoma") AND ("Stem Cell" OR "Stem Gene") AND ("Metastasis" OR "Recurrence"). A total of 12 studies were deemed eligible for inclusion. SOX2, IGF1R, SOX4, ALDH1, CD44, Cripto-1, OCT4, ARRB1, ARRB2, p-TFCP2L1, CDK1, DCLK1, and NANOG, which were all identified as CSC markers. Several of these markers have been implicated in the recurrence and metastasis of tumor in bladder cancer, which played a role as prognostic factor of bladder cancer. Given the pluripotent and highly proliferative properties of CSCs. CSCs may play a role in the complex biological behavior of bladder cancer, including, but not limited to, its high rates of recurrence, metastasis, and resistance to treatment. The detection of cancer stem cell markers offers a promising approach in determining the prognosis of bladder cancer. Further studies in this area are thus warranted and may contribute significantly to the overall management of bladder cancer.

Psychological Health of Surgeons in a Time of COVID-19: A Global Survey.

OBJECTIVE: To assess the degree of psychological impact among surgical providers during the COVID-19 pandemic. SUMMARY OF BACKGROUND DATA: The COVID-19 pandemic has extensively impacted global healthcare systems. We hypothesized that the degree of psychological impact would be higher for surgical providers deployed for COVID-19 work, certain surgical specialties, and for those who knew of someone diagnosed with, or who died, of COVID-19. METHODS: We conducted a global web-based survey to investigate the psychological impact of COVID-19. The primary outcomes were the depression anxiety stress scale-21 and Impact of Event Scale-Revised scores. RESULTS: A total of 4283 participants from 101 countries responded. 32.8%, 30.8%, 25.9%, and 24.0% screened positive for depression, anxiety, stress, and PTSD respectively. Respondents who knew someone who died of COVID-19 were more likely to screen positive for depression, anxiety, stress, and PTSD (OR 1.3, 1.6, 1.4, 1.7 respectively, all P < 0.05). Respondents who knew of someone diagnosed with COVID-19 were more likely to screen positive for depression, stress, and PTSD (OR 1.2, 1.2, and 1.3 respectively, all P < 0.05). Surgical specialties that operated in the head and neck region had higher psychological distress among its surgeons. Deployment for COVID- 19-related work was not associated with increased psychological distress. CONCLUSIONS: The COVID-19 pandemic may have a mental health legacy outlasting its course. The long-term impact of this ongoing traumatic event underscores the importance of longitudinal mental health care for healthcare personnel, with particular attention to those who know of someone diagnosed with, or who died of COVID-19.

Renal cell carcinoma with early skin metastasis and partial response on tyrosine kinase inhibitor: A case report.

INTRODUCTION AND IMPORTANCE: Renal cell carcinoma (RCC) skin metastasis is a rare disease. However, there are no data on the effect of a Tyrosine Kinase Inhibitor (TKI) on its treatment. CASE PRESENTATION: A 54-year-old male patient with renal cell carcinoma developed subcutaneous metastasis three months after radical nephrectomy and there was no discoloration or pain. Furthermore, an excision biopsy confirmed the metastatic lesion, and pazopanib was initiated as a treatment method. After 1-month of treatment, the patient developed ulceration and subsided after treatment was stopped. Similarly, a follow-up PET scan was performed almost a year after stopping the treatment, which showed improvement over metastatic pulmonary lesions. CLINICAL DISCUSSION: Renal cell carcinoma (RCC) major metastases were observed in pulmonary, costal, and skin. Tumor burden and location of metastasis influences progression free-survival of RCC patients treated with TKI. CONCLUSION: In this case, TKI treatment showed a long-term partial response, despite its lack of continuous therapy.

The Improvement of Patient's Quality of Life After Kidney Transplantation in Cipto Mangunkusumo Hospital, Indonesia.

OBJECTIVES: Kidney transplantation has become the chosen kidney replacement therapy for end stage chronic kidney disease. In Indonesia, no study about quality of life (QoL) in kidney transplantation recipient after surgery has been done. This study aims to determine whether there is a significant difference in the recipient's QoL before and after kidney transplantation surgery. METHODS AND MATERIALS: This was a prospective study using Kidney Disease QoL-Short Form (KDQoL-SF) questionnaire before and after surgery (first, third, and sixth month). Samples were consecutively taken from January 2016 until May 2016 and followed up to December 2016. KDQoL-SF has been validated in Indonesian language to assess recipient's QoL (Cronbach alfa >0,6). The data were analyzed using SPSS statistical software 21.0 version and repeated analysis of variance with posthoc comparison Bonferroni was used. RESULTS: There were 33 patients included in this study from January through December 2016. The average age was 44.6 ± 12.88 years old, and average body mass index was 23.8 ± 3.74 kg/m2. The most frequent comorbidity was hypertension (32, 97%). Compared to baseline, the QoL in recipients increased at the first, third, and sixth month after their operation. Major changes in the perceived QoL were noted only between the preoperative stage (median, 50%; interquartile range, [IQR]) ±20) and 1 month after operation (median, 90%; IQR, 0). CONCLUSIONS: This study showed that there were significant improvements in almost all aspect in recipient's QoL after kidney transplantation.

Genetic polymorphisms as prognostic factors for recurrent kidney stones: A systematic review and meta-analysis.

Genetic polymorphisms have been suggested as risk factors affecting the occurrence and recurrence of kidney stones, although findings regarding the latter remain inconclusive. We performed this systematic review and meta-analysis to clarify the associations between genetic polymorphisms and recurrent kidney stones. PubMed, SCOPUS, EMBASE, and Cochrane Library databases were searched through May 28th, 2020 to identify eligible studies. The Quality in prognostic studies (QUIPS) tool was used to evaluate bias risk. Allelic frequencies and different inheritance models were assessed. All analyses were performed using Review manager 5.4. A total of 14 studies were included for meta-analysis, assessing urokinase (ApaL1) and vitamin D receptor (VDR) (ApaI, BsmI, FokI, and TaqI) gene polymorphisms. The ApaLI polymorphism demonstrated protective association in the recessive model [odds ratio (OR) 0.45, P < 0.01] albeit higher risk among Caucasians in the heterozygous model (OR 16.03, P < 0.01). The VDR-ApaI polymorphism showed protective association in the dominant model (OR 0.60, P < 0.01). Among Asians, the VDR-FokI polymorphism recessive model showed significant positive association (OR 1.70, P < 0.01) and the VDR-TaqI polymorphism heterozygous model exhibited protective association (OR 0.72, P < 0.01). The VDR-BsmI polymorphism was not significantly associated with recurrent kidney stones in any model. Urokinase-ApaLI (recessive model), VDR-ApaI (dominant model), and VDR-TaqI (heterozygous model) polymorphisms were associated with decreased recurrent kidney stone risk whereas urokinase-ApaLI (heterozygous model) and VDR-FokI polymorphisms were associated with increased risk among Caucasians and Asians, respectively. These findings will assist in identifying individuals at risk of kidney stone recurrence.

Laparoscopic procurement of single versus multiple artery kidney allografts: Meta-analysis of comparative studies.

Laparoscopic donor nephrectomy has become the standard procedure to procure kidney graft. Transplantation using multiple arteries allograft is technically more challenging and still controversial with respect to renal transplantation outcomes. The objective of this study was to examine the transplantation outcome in both donor and recipient outcome of multiple arteries allograft kidney compared with single renal artery kidney. Eligible studies were identified from electronic databases: PubMed, Cochrane CENTRAL, Science Direct, and CINAHL as of October 2016. Relevant parameters explored using Review Manager V5.2 included donor and recipient outcomes. Twenty-four studies were included in this meta-analysis. Compared with SA, MA kidneys were associated with a longer donor operative time. There was no difference between donor length of stay, intraoperative blood loss, hospital stay, first warm ischemic time (WIT-I), and donor surgical complications in donors with multiple arteries compared with single. There was an increased risk of one-year graft loss (OR 1.57, 95% CI 1.09 to 2.26, p = 0.016), recipient vascular complications and recipient ureteral complications in multiple arteries compared with single artery allografts. Kidney transplantation with multiple arteries is relatively as safe as single artery in terms of donor outcomes. However, transplantation with multiple arteries allograft had several potential negative impacts on the recipient outcomes.

Prostate specific antigen (PSA) kinetic as a prognostic factor in metastatic prostate cancer receiving androgen deprivation therapy: systematic review and meta-analysis.

Aim: Metastatic prostate cancer (mPCa) has a poor outcome with median survival of two to five years. The use of androgen deprivation therapy (ADT) is a gold standard in management of this stage.  Aim of this study is to analyze the prognostic value of PSA kinetics of patient treated with hormonal therapy related to survival from several published studies Method: Systematic review and meta-analysis was performed using literature searching in the electronic databases of MEDLINE, Science Direct, and Cochrane Library. Inclusion criteria were mPCa receiving ADT, a study analyzing Progression Free Survival (PFS), Overall Survival (OS), or Cancer Specific Survival (CSS) and prognostic factor of survival related to PSA kinetics (initial PSA, PSA nadir, and time to achieve nadir (TTN)). The exclusion criteria were metastatic castration resistant of prostate cancer (mCRPC) and non-metastatic disease. Generic inverse variance method was used to combine hazard ratio (HR) within the studies. Meta-analysis was performed using Review Manager 5.2 and a p-value <0.05 was considered statistically significant. Results: We found 873 citations throughout database searching with 17 studies were consistent with inclusion criteria. However, just 10 studies were analyzed in the quantitative analysis. Most of the studies had a good methodological quality based on Ottawa Scale. No significant association between initial PSA and PFS. In addition, there was no association between initial PSA and CSS/ OS. We found association of reduced PFS (HR 2.22; 95% CI 1.82 to 2.70) and OS/ CSS (HR 3.31; 95% CI 2.01-5.43) of patient with high PSA nadir. Shorter TTN was correlated with poor result of survival either PFS (HR 2.41; 95% CI 1.19 - 4.86) or CSS/ OS (HR 1.80; 95%CI  1.42 - 2.30) Conclusion: Initial PSA before starting ADT do not associated with survival in mPCa.  There is association of PSA nadir and TTN with survival.

Prostate cancer detection rate in Indonesian men.

PURPOSES OF THE STUDY: To evaluate the overall detection rate of prostate cancer in biopsies according to serum prostate-specific antigen levels, determine the number of cores biopsied in Indonesian men, and provide a correlated staging of prostate cancer patients at varying intervals of prostate-specific antigen levels. METHODS: We retrospectively analyzed the data from Indonesian men who had undergone prostate biopsy at two national referral medical centers in Jakarta from January 1995 to December 2014. Prostate biopsy was performed when levels of prostate-specific antigen were>4.0 ng/mL or malignancy was suspected upon digital rectal examination. RESULTS: Of 2942 men who underwent biopsies, 844 (28.7%) were diagnosed with prostate cancer. When patients were stratified into five subgroups by serum prostate-specific antigen levels (< 4.0, 4.0-9.9, 10.0-19.9, 20.0-100.0, and>100.0 ng/mL), the overall detection rate of prostate cancer was 21.0%, 9.3%, 13.1%, 35.4%, and 92.9%, respectively. The detection rate was significantly higher in patients who underwent 10-core biopsies than in patients who underwent 6-core biopsies (31.6% vs. 22.4%, p<0.001). The receiver operating characteristic analysis to detect locally advanced/metastatic prostate cancer found that serum prostate-specific antigen levels of 42.7 ng/mL had a sensitivity of 74%, specificity of 73%, positive predictive value of 85.2%, and negative predictive value of 57.5%, with area under the curve of 0.81 (95% confidence interal 0.78 to 0.84). CONCLUSION: The overall detection rate of prostate cancer in Indonesian men was 28.7%. The prostate cancer detection rate appeared to be lower than that observed in white men.

The impact of obesity towards prostate diseases.

Evidence has supported obesity as a risk factor for both benign prostate hyperplasia (BPH) and prostate cancer (PCa). Obesity causes several mechanisms including increased intra-abdominal pressure, altered endocrine status, increased sympathetic nervous activity, increased inflammation process, and oxidative stress, all of which are favorable in the development of BPH. In PCa, there are several different mechanisms, such as decreased serum testosterone, peripheral aromatization of androgens, insulin resistance, and altered adipokine secretion caused by inflammation, which may precipitate the development of and even cause high-grade PCa. The role of obesity in prostatitis still remains unclear. A greater understanding of the pathogenesis of prostate disease and adiposity could allow the development of new therapeutic markers, prognostic indicators, and drug targets. This review was made to help better understanding of the association between central obesity and prostate diseases, such as prostatitis, BPH, and PCa.
