RESUMEN
OBJECTIVE: To estimate prostate cancer (PC) survival in Mexico and explore survival disparities according to the marginalization level of residence place. MATERIALS AND METHODS: A nationwide administrative claims database (4 110 men) whose PC treatment was financed by Seguro Popular between 2012-2016, was cross-linked to the National Mortality Registry up to December 2019. Patients were classified according to their oncological risk at diagnosis and the marginalization level of the residence municipality. Cox proportional hazards regression was used to estimate multivariable survival functions. RESULTS: Five-years PC survival (69%; 95%CI: 68,71%) ranged from 72% to 54% at very low and very high marginalization, respectively (p for trend<0.001). The lowest PC survival was observed in men with high-risk PC (47%; 95%CI: 33,66%) residents in very high marginalization municipalities. CONCLUSIONS: Overall, PC survival was lower than that reported in other Latin American countries. The distribution of oncologic risk and survival differences across marginalization levels suggests limited early detection and cancer health disparities.
RESUMEN
BACKGROUND: Metabolic syndrome (MS) with mixed dyslipidemia and prostate cancer (PC) are relevant health problems among Mexican men. However, there is no information regarding the association between MS and PC for this population. AIM OF THE STUDY: To evaluate this association in a population case-control study in Mexico City. METHODS: We analyzed the information from 394 incident PC-cases and 793 population age-matched (± 5 years) controls, identified in Mexico City (2011-2014). For cases, Gleason score at diagnosis was available. We defined MS history based on the self-report of hypertension, hypercholesterolemia, hypertriglyceridemia, and diabetes; obesity was evaluated using weight-change trajectories throughout life. In addition, the four MS-typologies described for Mexican population were used. The association between MS with PC and histological PC differentiation was evaluated using independent multivariate logistic regression models. RESULTS: MS history was associated with a high PC probability (OR 1.94; 95% CI 1.37-2.75). Lipid alterations, arterial hypertension, and a marked weight increase throughout life were associated with increased PC probability; however, only the marked weight increase was associated with more poorly differentiated PC (Gleason ≥8) (OR 2.79; 95% CI 1.50-5.17). CONCLUSION: Like other populations, in this Mexican study, MS and some of its components were identified as potential PC risk factors. MS-lipid alteration typology seems to be relevant; however, the novelty of this approach together with the retrospective nature of this study, indicate that a prospective evaluation of the MS typologies and PC association must be performed.

OBJECTIVE: To evaluate the association between life-course leisure-time physical activity (PA) and prostate cancer (PC) among males living in Mexico City. Materials and meth-ods. Information from 394 incident PC cases and 794 popula-tion controls matched by age (± 5 years), was analyzed. Using leisure-time PA information at different life stages, life-course PA patterns were constructed. The association between PA and PC was estimated using an unconditional logistic regres-sion model. RESULTS: Three life-course PA patterns were identified: low PA (71.0%), moderate PA (22.0%), and high PA (7.0%); this last pattern was characterized by higher levels and consistent PA practice. Compared with inactive males, those in the high PA pattern (OR: 0.50; 95%CI: 0.26-0.93) had significantly lower PC odds. CONCLUSION: Intense and regular PA could reduce the possibility of PC. These results are in accordance with PA World Health Organization rec-ommendations.

Resumen: Objetivo: Evaluar la asociación entre la actividad física (AF) en la vida y el cáncer de próstata (CP) en hombres. Material y métodos: Se analizó la AF de 394 casos incidentes de CP y 794 controles poblacionales pareados por edad (± 5 años). Se utilizó la información de AF en diferentes etapas para generar los patrones de AF a lo largo de la vida. La asociación entre AF y CP se estimó mediante regresión logística no condicionada. Resultados: Se identificaron tres patrones de AF: baja (71.0%), moderada (22.0%) y alta (7.0%); este último patrón se caracterizó por una AF consistentemente mayor a lo largo de la vida. Comparado con los hombres inactivos, aquéllos en el patrón de alta AF (RM= 0.50; IC95% = 0.26-0.93) presentaron menos posibilidades de tener CP. Conclusión: El papel protector de la AF parece estar en función de la intensidad y regularidad de su práctica y apoyan las recomendaciones de la OMS.

PURPOSE OF REVIEW: The aim of this review is to provide an overview of epidemiology, risk factors, and treatment of urological malignancies in renal transplant recipients (RTR). RECENT FINDINGS: Although optimal immunosuppressive therapy and cancer management in these patients remain controversial, adherence to general guidelines is recommended. Kidney transplantation is recognized as the standard of care for the treatment of end-stage renal disease (ESRD) as it offers prolonged survival and better quality of life. In the last decades, survival of RTRs has increased as a result of improved immunosuppressive therapy; nonetheless, the risk of developing cancer is higher among RTRs compared to the general population. Urological malignancies are the second most common after hematological cancer and often have more aggressive behavior and poor prognosis.

BACKGROUND: The role of cytoreductive nephrectomy on the treatment of metastatic renal cell carcinoma (mRCC) is controversial due to its high complexity. OBJECTIVE: To identify risk factors associated to postoperative complications in patients with mRCC after cytoreductive nephrectomy. METHOD: We conducted a retrospective, observational study in 67 patients who underwent cytoreductive nephrectomy for the management of mRCC. Demographic, perioperative and clinicopathologic -characteristics were registered. Surgical complications were classified using the Clavien-Dindo system; major complications were those of grade 3 or higher. We performed a binary logistic regression analysis to identify risk factors associated with surgical complications. RESULTS: Mean age was 56 years (37-83). Symptoms were present in 58 patients (89.7%). Weight loss was the predominant symptom (50.8%). Mean tumor diameter was 10.8 cm (4.6-22.5 cm). The rate of postoperative complications was 65%; 21 patients (31.4%) had major complications. Risk factors were estimated blood loss > 500 ml (OR 44.5, CI 95% 2.51-789, p = 0.01) and tumor diameter > 10 cm (OR 17.9, CI 95% 1.2-273, p = 0.04). CONCLUSIONS: Cytoreductive nephrectomy is a good option in highly selected patients with mRCC. Our major complication rate was 31.4%. Risk factors associated were blood loss and tumor diameter.
ANTECEDENTES: El papel de la nefrectomía citorreductora como tratamiento del carcinoma de células renales metastásico (CCRm) es controversial debido a su alta complejidad. OBJETIVO: Identificar factores de riesgo para complicaciones posquirúrgicas en pacientes con CCRm tratados con nefrectomía citorreductora. MÉTODO: Estudio retrospectivo, observacional, de 67 pacientes tratados con nefrectomía citorreductora por CCRm. Se registraron las características demográficas, perioperatorias y clinicopatológicas. Las complicaciones posquirúrgicas fueron clasificadas con el sistema Clavien-Dindo (mayores aquellas de grado 3 o superior). Se realizó un análisis de regresión logística binaria para identificar factores de riesgo para complicaciones. RESULTADOS: La edad media fue de 56 años (rango: 37-83), y 58 pacientes (89.7%) presentaron síntomas, predominando la pérdida de peso (50.8%). El diámetro tumoral medio fue de 10.8 cm (rango: 4.6-22.5). Un 65% tuvo complicaciones posquirúrgicas; en el 31.4% fueron mayores. Los factores de riesgo asociados fueron el sangrado transoperatorio ≥ 500 ml (odds ratio [OR]: 44; intervalo de confianza del 95% [IC 95%]: 2.51-789; p = 0.01) y el diámetro tumoral > 10 cm (OR: 17.9; IC 95%: 1.2-273; p = 0.04). CONCLUSIONES: La nefrectomía citorreductora es una opción de tratamiento para pacientes estrictamente seleccionados. Nuestra tasa de complicaciones mayores fue del 31.4%. Los factores de riesgo asociados fueron el sangrado transoperatorio y el diámetro tumoral.

Epidemiological studies related to androgens and prostate cancer (PC) have focused on serum determination of testosterone, androstenedione (A4), and DHEA, with inconsistent results. Herein, we hypothesized that differences in androgen biosynthetic and metabolic pathways, rather than differences in specific androgen concentrations, are associated with prostatic carcinogenesis. Therefore, spot urine samples from 111 incident PC cases with Gleason score at diagnosis and 227 healthy population controls, were analyzed. Urinary androgen concentrations (nanograms/milligrams of creatinine) were determined by ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS). Using a factor analysis, we identified three androgen urinary excretion patterns. In a subsample, we evaluated a modification effect of the androgen receptor (AR) CAG polymorphism. Pattern I, characterized by A4 and testosterone hydroxylated metabolites (11ß-OHT; 2ß-OHT; 15ß-OHT; 2α-OHT; 6ß-OHT), was associated with high PC odds among carriers of AR gene (CAG)>19 repeats (OR: 3.67 95% CI: 1.23-11.0; P for interaction= 0.009). Conversely, higher testosterone excretion (pattern III), was marginally associated with lower (OR: 0.35 95% CI: 0.12-1.00, P for trend= 0.08) poorly differentiated PC (Gleason ≥8). No clear association was observed with pattern II (DHEA; 16α and 16ß-OHT). Our results were consistent with the previous evidence which suggests that the C11-oxy backdoor pathway is important for prostatic carcinogenesis. Androgen urine excretion analysis could be useful for PC diagnosis, treatment, and prognosis; however, further studies with a larger number of samples and the urinary determination of 11-ketoandrogens are necessary.

Background: The negative impact of tobacco smoking on renal function has been widely studied. However, there is limited knowledge about the effect of smoking on pre-operative and post-operative renal function in living kidney donors. Objective: The objective of the study was to evaluate the short- and mid-term impact of smoking on donor renal function. Methods: This is a retrospective study of 308 patients who underwent living donor nephrectomy (LDN) at a tertiary referral hospital. We compared baseline characteristics as well as functional outcomes following LDN according to history of tobacco smoking. Estimated glomerular filtration rate (eGFR) was calculated with the modification of diet in renal disease equation in 6 time periods: pre-operative, 1 week, 1 month, 6 months, 12 months, and 24 months after surgery. We performed a Kaplan-Meier analysis for chronic kidney disease (CKD) outcome and binary logistic regression analysis to identify risk factors associated with CKD at 24 months of follow-up. Results: Among donors, 106 (34.4%) reported a smoking history before nephrectomy. Smoking donors had worse pre-operative eGFR than non-smokers (90 ± 26.3 mL/min/1.73m2 vs. 96 ± 27 mL/min/1.73 m2, respectively; p = 0.02) and lower eGFR at 1 week (p = 0.01), 1 month (p ≤ 0.01), 6 months (p = 0.01), and 12 months (p = 0.01) after LDN. Tobacco smoking (OR 3.35, p ≤ 0.01) and age ≥ 40 years at donation (OR 6.59, p ≤ 0.01) were associated with post-operative development of CKD at 24 months after LDN. Conclusions: Living kidney donors with a tobacco smoking history had an increased risk of developing chronic kidney disease following nephrectomy. Smoking-cessation strategies should be implemented.

BACKGROUND: The incidence of renal cell carcinoma (RCC) is increasing globally due to an aging population and widespread use of imaging studies. OBJECTIVE: The aim of this study was to describe the characteristics and perioperative outcomes of RCC surgery in very elderly patients (VEP), ≥ 75 years of age. METHODS: This is a retrospective comparative study of 3656 patients who underwent the treatment for RCC from 1990 to 2015 in 28 centers from eight Latin American countries. We compared baseline characteristics as well as clinical and perioperative outcomes according to age groups (less than 75 vs. ≥75 years). Surgical complications were classified with the Clavien-Dindo score. We performed logistic regression analysis to identify factors associated with perioperative complications. RESULTS: There were 410 VEP patients (11.2%). On bivariate analysis, VEP had a lower body mass index (p less than 0.01) and higher ASA score (ASA > 2 in 26.3% vs. 12.4%, p < 0.01). There was no difference in performance status and clinical stage between the study groups. There were no differences in surgical margins, estimated blood loss (EBL), complication, and mortality rates (1.3% vs. 0.4%, p = 0.17). On multivariate regression analysis, age ≥75 years (odds ratio [OR] 2.33, p less than 0.01), EBL ≥ 500 cc (OR 3.34, p less than 0.01), and > pT2 stage (OR 1.63, p = 0.04) were independently associated with perioperative complications. CONCLUSIONS: Surgical resection of RCC was safe and successful in VEP. Age ≥75 years was independently associated with 30-day perioperative complications. However, the vast majority were low-grade complications. Age alone should not guide decision-making in these patients, and treatment must be tailored according to performance status and severity of comorbidities.

BACKGROUND: To evaluate demographic, clinical and pathological characteristics of small renal masses (SRM) (≤ 4 cm) in a Latin-American population provided by LARCG (Latin-American Renal Cancer Group) and analyze predictors of survival, recurrence and metastasis. METHODS: A multi-institutional retrospective cohort study of 1523 patients submitted to surgical treatment for non-metastatic SRM from 1979 to 2016. Comparisons between radical (RN) or partial nephrectomy (PN) and young or elderly patients were performed. Kaplan-Meier curves and log-rank tests estimated 10-year overall survival. Predictors of local recurrence or metastasis were analyzed by a multivariable logistic regression model. RESULTS: PN and RN were performed in 897 (66%) and 461 (34%) patients. A proportional increase of PN cases from 48.5% (1979-2009) to 75% (after 2009) was evidenced. Stratifying by age, elderly patients (≥ 65 years) had better 10-year OS rates when submitted to PN (83.5%), than RN (54.5%), p = 0.044. This disparity was not evidenced in younger patients. On multivariable model, bilaterality, extracapsular extension and ASA (American Society of Anesthesiologists) classification ≥3 were predictors of local recurrence. We did not identify significant predictors for distant metastasis in our series. CONCLUSIONS: PN is performed in Latin-America in a similar proportion to developed areas and it has been increasing in the last years. Even in elderly individuals, if good functional status, sufficiently fit to surgery, and favorable tumor characteristics, they should be encouraged to perform PN. Intending to an earlier diagnosis of recurrence or distant metastasis, SRM cases with unfavorable characteristics should have a more rigorous follow-up routine.

ABSTRACT Purpose: To provide a summary and recommendations for the set-up of strategies for cancer patients care in genitourinary oncology clinics during the pandemic and in the recovery period. Material and Methods: A non-systematic review of available literature on the management of urological malignancies during the COVID-19 pandemic was performed to summarize recommendations to improve the diagnosis and treatment of urological cancers during and after the contingence, including clinical and research aspects. Results: Urological cancer diagnosis and management should be tailored according to the severity of the COVID-19 crisis in each region and the aggressiveness of each tumor. Clinicians should adhere to strict protocols in order to prioritize the attention of patients with high-risk malignancies while optimizing resources to avoid the saturation of critical care services. Conclusions: During the COVID-19 pandemic urological cancer care has been severely impaired. For proper patient management, multidisciplinary approach is encouraged tailoring therapy according to COVID-19 regional behavior and local institutional resources. Patients with high-risk malignancies should be prioritized.

BACKGROUND: Symptomatic urinary tract infection (UTI) is the most common infectious complication in renal transplant recipients (RTRs). Fosfomycin (FOS) is an attractive alternative for prophylaxis because it does not interact with immunosuppressants; although 90% is excreted unchanged in the urine, it does not require adjustment for renal function for single dose prophylaxis. METHODS: RTRs were recruited into this randomized, double-blind, placebo-controlled trial. Participants were randomized (1:1) to receive one 4 g dose of FOS disodium intravenously 3 h (FOS group) or placebo (placebo group) before placement and removal of a urinary catheter and before removal of a double-J ureteral stent. All participants received prophylaxis with trimethoprim/sulfamethoxazole. The main outcome was a comparison of the mean number of symptomatic UTI and asymptomatic bacteriuria (AB) episodes per patient during a 7-week follow-up period. The study was registered at ClinicalTrials.gov, NTC03235947. RESULTS: Eighty-two participants were included (41 in the FOS group and 41 in placebo group). The mean number of AB or symptomatic UTI episodes per patient was lower in the FOS group [intention-to-treat (ITT) 0.29 versus 0.60, P = 0.04]. The incidence of symptomatic UTI was lower in the FOS group (ITT, 7.3% versus 36.6%, P = 0.001), and there was no difference in the incidence of AB between both groups. The incidence of adverse events was similar in both groups. CONCLUSIONS: FOS addition is an effective and safe strategy to reduce the number of symptomatic UTIs during the first 7 weeks after renal transplant.

Abstract: Prostate-specific antigen (PSA)-based early detection for prostate cancer is the subject of intense debate. Implementation of organized prostate cancer screening has been challenging, in part because the PSA test is so amenable to opportunistic screening. To the extent that access to cancer screening tests increases in low- and middle-income countries (LMICs), there is an urgent need to thoughtfully evaluate existing and future cancer screening strategies to ensure benefit and control costs. We used Mexico's prostate cancer screening efforts to illustrate the challenges LMICs face. We provide five considerations for policymakers for a smarter approach and implementation of PSA-based screening.
