RESUMEN

Here, in a multi-ancestry genome-wide association study meta-analysis of kidney cancer (29,020 cases and 835,670 controls), we identified 63 susceptibility regions (50 novel) containing 108 independent risk loci. In analyses stratified by subtype, 52 regions (78 loci) were associated with clear cell renal cell carcinoma (RCC) and 6 regions (7 loci) with papillary RCC. Notably, we report a variant common in African ancestry individuals ( rs7629500 ) in the 3' untranslated region of VHL, nearly tripling clear cell RCC risk (odds ratio 2.72, 95% confidence interval 2.23-3.30). In cis-expression quantitative trait locus analyses, 48 variants from 34 regions point toward 83 candidate genes. Enrichment of hypoxia-inducible factor-binding sites underscores the importance of hypoxia-related mechanisms in kidney cancer. Our results advance understanding of the genetic architecture of kidney cancer, provide clues for functional investigation and enable generation of a validated polygenic risk score with an estimated area under the curve of 0.65 (0.74 including risk factors) among European ancestry individuals.

RESUMEN

ABSTRACT Objective: To report outcomes from the largest multicenter series of penile cancer patients undergoing video endoscopic inguinal lymphadenectomy (VEIL). Materials and Methods: Retrospective multicenter analysis. Authors of 21 centers from the Penile Cancer Collaborative Coalition-Latin America (PeC-LA) were included. All centers performed the procedure following the same previously described standardized technique. Inclusion criteria included penile cancer patients with no palpable lymph nodes and intermediate/high-risk disease and those with non-fixed palpable lymph nodes less than 4 cm in diameter. Categorical variables are shown as percentages and frequencies whereas continuous variables as mean and range. Results: From 2006 to 2020, 210 VEIL procedures were performed in 105 patients. Mean age was 58 (45-68) years old. Mean operative time was 90 minutes (60-120). Mean lymph node yield was 10 nodes (6-16). Complication rate was 15.7%, including severe complications in 1.9% of procedures. Lymphatic and skin complications were noted in 8.6 and 4.8% of patients, respectively. Histopathological analysis revealed lymph node involvement in 26.7% of patients with non-palpable nodes. Inguinal recurrence was observed in 2.8% of patients. 10y- overall survival was 74.2% and 10-y cancer specific survival was 84.8%. CSS for pN0, pN1, pN2 and pN3 were 100%, 82.4%, 72.7% and 9.1%, respectively. Conclusion: VEIL seems to offer appropriate long term oncological control with minimal morbidity. In the absence of non-invasive stratification measures such as dynamic sentinel node biopsy, VEIL emerged as the alternative for the management of non-bulky lymph nodes in penile cancer.

RESUMEN

ABSTRACT Prostate cancer is the most common invasive cancer in men. Radical prostatectomy (RP) is a definitive treatment option, but biochemical recurrence can reach 40%. Salvage lymphadenectomy is a relatively recent approach to oligometasis and has been rapidly diffused primarily due to improvement in imaging diagnosis and results showing possibly promising therapy. A systematic literature review was performed in March 2020, according to the PRISMA statement. We excluded studies with patients with suspicion or confirmation of visceral and / or bone metastases. A total of 27 articles were included in the study. All studies evaluated were single arm, and there were no randomized studies in the literature. A total of 1,714 patients received salvage lymphadenectomy after previous treatment for localized prostate cancer. RP was the most used initial therapeutic approach, and relapses were based on PET / CT diagnosis, with Coline-11C being the most widely used radiopharmaceutical. Biochemical response rates ranged from 0% to 80%. The 5 years - Free Survival Biochemical recurrence was analyzed in 16 studies with rates of 0% up to 56.1%. The articles do not present high levels of evidence to draw strong conclusions. However, even if significant rates of biochemical recurrence are not evident in all studies, therapy directed to lymph node metastases may present good oncological results and postpone the onset of systemic therapy. The long-term impact in overall survival and quality of life, as well as the best strategies for case selection remains to be determined.

RESUMEN

ABSTRACT Standard radical cystectomy (RC) in women involves removal of the distal ureters, bladder, proximal urethra, uterus, ovaries, and adjacent vagina. Furthermore, pelvic organ-preserving RC to treat selected women has become an accepted technique and may confer better postoperative sexual and urinary functions than standard RC, avoiding complications such as incontinence, prolapse, neobladder-vaginal fistula (NVF), and sexual dysfunction, without compromising oncological outcome. This article reports a different surgical approach: a patient who underwent a cutaneous continent reservoir and neovagina construction using a previous ileal orthotopic neobladder after RC. Patient presented no complications and she has no evidence of recurrent disease and is sexually active, with a satisfactory continent reservoir. This case is the first report of this procedure that was able to treat concomitant dyspareunia caused by short vagina and neobladder-vaginal fistula. In conclusion, standard radical cystectomy with no vaginal preservation can have a negative impact on quality of life. In the present case, we successfully treated neobladder fistula and short vagina by transforming a previous ileal orthotopic neobladder into two parts: a continent reservoir and a neovagina. However, to establish the best approach in such patients, more cases with long-term follow-up are needed.

RESUMEN

[Purpose] To investigate the effect of electrical stimulation and pelvic floor muscle training on muscle strength, urinary incontinence and erectile function in men with prostate cancer treated by radical prostatectomy. [Subjects and Methods] One hundred twenty-three males were randomized into 3 groups 1 month after RP: (G1, n=40) control; (G2, n=41) guideline: patients were instructed to perform three types of home exercises to strengthen the pelvic floor and (G3, n=42) electrical stimulation: patients in this group were also instructed to perform exercises as group G2, and also received anal electro-stimulation therapy, twice a week for 7 weeks. The primary outcome assessment was based on the measurement of the recovery of pelvic floor muscle strength between groups. Secondary outcomes were: 1 hour Pad Test, ICIQ-SF, IIEF-5 and IPSS. Data were obtained preoperatively and at 1, 3 and 6 months after surgery. [Results] There was no significant difference in the demographic data among groups. Greater urinary leakage and pelvic floor muscle weakness in the first month compared to pre treatment improved after 3 and 6 months postoperative, without difference among groups. [Conclusion] The muscle strength recovery occurs independently of the therapy employed. Pelvic floor exercises or electrical stimulation also did not have an impact on the recovery of urinary continence and erectile function in our study.

RESUMEN

ABSTRACT Background and Purpose: Recent advances in cancer treatment have resulted in bet- ter prognosis with impact on patient's survival, allowing an increase in incidence of a second primary neoplasm. The development of minimally invasive surgery has provided similar outcomes in comparison to open surgery with potentially less mor- bidity. Consequently, this technique has been used as a safe option to simultaneously treat synchronous abdominal malignancies during a single operating room visit. The objective of this study is to describe the experience of two tertiary cancer hospitals in Brazil, in the minimally invasive treatment of synchronous abdominal neoplasms and to evaluate its feasibility and peri-operative results. Materials and Methods: We retrospectively reviewed the data from patients who were submitted to combined laparoscopic procedures performed in two tertiary hospitals in Brazil from May 2009 to February 2015. Results: A total of 12 patients (9 males and 3 females) with a mean age of 58.83 years (range: 33 to 76 years) underwent combined laparoscopic surgeries for the treatment of at least one urological disease. The total average duration of surgery was 339.8 minutes (range: 210 to 480 min). The average amount of intraoperative bleeding was 276.6mL (range: 70 to 550mL) and length of hospitalization was 5.08 days (range: 3 to 10 days). Two patients suffered minor complications regarding Clavien system during the immediate postoperative period. Conclusions: Combined laparoscopic surgery for the treatment of synchronous tumors is feasible, viable and safe. In our study, there was a low risk of postoperative morbidity.

RESUMEN

BACKGROUND: To evaluate the feasibility, clinical and perioperative outcomes of laparoscopic retroperitoneal lymph node dissection (L-RPLND) in the management of patients with germ cell tumors (GCT) and residual post-chemotherapy mass. METHODS: We report our experience of 25 patients treated with L-RPLND between 2008 and 2015. All 25 patients were diagnosed with GCT by primary pathological evaluation of the specimens after orchiectomy. All patients received cisplatin-based chemotherapy. The technique consisted of L-RPLND excision of the residual mass using unilateral template dissection. We assessed perioperative data and histological findings. RESULTS: Surgery was successfully completed in 24 (96%) patients, 1 patient required an open surgery due to intense adhesions of the mass to the inferior vena cava. Mean operation time was 213 minutes. Mean blood loss was 260 mL. Postoperative complications were upper limb osteomuscular pain in 2 patients and chylous ascites in 1 patient. Mean postoperative hospital stay was 2 days. The median residual mass diameter was 3.3 cm (range 1.1-6.6 cm). Histopathological findings were necrotic tissue in 9 patients, teratoma in 9 patients, viable tumor in 6 patients, and Castleman disease in 1 patient. The median follow-up was 30 months. Normal antegrade ejaculation was preserved in all patients. CONCLUSIONS: Laparoscopic postchemotherapy RPLND is a feasible, safe, and highly oncologically efficient procedure, which has the benefits of minimally invasive surgery.

RESUMEN

PURPOSE: Little is known about the effects of literacy levels on prostate cancer screening. This study evaluates the association between literacy, compliance with screening, and biopsy findings in a large Brazilian screening study. MATERIALS AND METHODS: We analyzed 17,571 men screened for PCa with digital rectal examination (DRE) and total and free prostate-specific antigen (PSA) from January 2004 to December 2007. Of those, 17,558 men had information regarding literate status. Full urological evaluation in a specialized cancer center was recommended in the case of: a) suspicious DRE, b) PSA > 4.0 ng/mL, or c) PSA 2.5-3.9 ng/mL and free/total PSA (f/tPSA) ratio 15%. Transrectal ultrasound guided prostate biopsy (14 cores) was performed upon confirmation of these findings after the patient's consent. Patients' compliance with screening recommendations and biopsy results were evaluated according to literacy levels. RESULTS: an abnormal PSA, a suspicious DRE, or both were present in 73.2%, 19.7%, and 7.1% of those men who underwent biopsy, respectively. PCa was diagnosed in 652 men (3.7%). Previous PSAs or DREs were less common among illiterate men (p < 0.0001). Additionally, illiterate men were less prone to attend to further evaluations due to an abnormal PSA or DRE (p < 0.0001). PSA levels > 10 mg/mL (p = 0.03), clinical stage > T2a (p = 0.005), and biopsy Gleason > 7 (p = 0.02) were more common among illiterate men. CONCLUSIONS: In a screened population, literacy levels were associated with prior PCa evaluations and with compliance with screening protocols. Illiterate men were at higher risk of being diagnosed with more advanced and aggressive PCa.

RESUMEN

PURPOSE: Simple diversions are underutilized, mostly for unfit, bedridden, and very self-limited patients requiring palliative surgical management due to life-threatening conditions. Experience with cutaneous ureterostomy (CU) as palliative urinary diversion option for unfit bladder cancer patients is reported. METHODS: We retrospectively reviewed clinical and operative parameters of 41 patients who underwent CU following RC in three specialized Cancer Centers from July/2005 to July/2010. Muscle-invasive disease (clinical Stage T2/worse), multifocal high-grade tumor, and carcinoma in situ refractory to intravesical immunotherapy were the main indications for RC. Double-J ureteral stents were used in all patients and replaced every 6 months indefinitely. Peri-operative morbidity and mortality were evaluated. RESULTS: Median age was 69 years (interquartile range--IQR 62, 76); 30 (73%) patients were men. Surgery in urgency setting was performed in 25 (61%) of patients, most due to severe bleeding associated with hemodynamic instability; 14 patients (34%) showed an American Society of Anesthesiologists score 4. Median operative time was 180 minutes (IQR 120, 180). Peri-operative complications occurred in 30 (73%) patients, most Clavien grade I and II (66.6 %). There was no per-operative death. Re-intervention was necessary in 7 (17%) patients. Overall survival was 24% after 9.4 months follow-up. CONCLUSIONS: CU with definitive ureteral stenting represents a simplified alternative for urinary diversion after palliative cystectomy in unfit patients. It can be performed quickly, with few early and late postoperative complications allowing RC in a group of patients otherwise limited to suboptimal alternatives. Future studies regarding the quality of life are warranted.

OBJETIVO: Relatar a experiência do emprego da ureterostomia cutânea (UC) como forma de derivação urinária definitiva em pacientes portadores de neoplasia vesical avançada, em más condições clínicas e que necessitam de tratamento paliativo. MÉTODOS: Foram analisados retrospectivamente os parâmetros clínicos e operatórios de 41 pacientes submetidos a cistectomia radical e UC em três centros oncológicos especializados. A UC foi a derivação urinária escolhida quando os pacientes não apresentavam condições clínicas de serem submetidos a outro tipo de derivação . Foram avaliados a morbidade peri-operatória e a sobrevida global. RESULTADOS: A idade média dos pacientes foi de 69 anos (intervalo interquartil - IQR 62, 76); 30 (73%) pacientes eram do sexo masculino. Vinte e cinco pacientes (61%) foram submetidos a cirurgia de urgência sendo a maioria devido a hemorragia grave associada a instabilidade hemodinâmica. O tempo cirúrgico médio foi de 180 minutos (IQR 120, 180). As complicações peri-operatórias ocorreram em 30 (73%) pacientes sendo a maioria classificadas como "Clavien" graus I e II (66,6%). Não houve óbito per-operatório. A reabordagem cirúrgica foi necessária em 7 (17%) dos pacientes e a sobrevida global foi de 24% após 9,4 meses de seguimento. CONCLUSÕES: A UC com implante de "stent" ureteral é uma alternativa simples de derivação urinária, após cistectomia paliativa, em pacientes sem condições clínicas de serem submetidos a procedimentos cirúrgicos mais complexos. A UC é um procedimento rápido e apresenta taxas de complicações aceitáveis. Essa alternativa cirúrgica permite melhorar a qualidade de vida dos pacientes portadores de tumores vesicais localmente avançados.

RESUMEN

UNLABELLED: What's known on the subject? and What does the study add? In spite of its low specificity, PSA is the most widely used screening test for prostate cancer (PCa), and is considered the main cause of the stage migration recently observed. The ratio of free to total PSA (%fPSA) has been shown to increase PSA accuracy in cancer detection; however, few screening studies have systematically evaluated its role in cancer detection rates in men with PSA levels <4.0 ng/mL and normal DRE. The present study supports a possible role of %fPSA as an adjunct to screening in men with total PSA 2.5-4.0 ng/mL and normal DRE, with a marked increase in cancer detection rates in a large Brazilian PCa screening study. We believe that %fPSA maybe a useful refinement to biopsy indications in men with low PSA levels. OBJECTIVE: • To evaluate the role of the free to total prostate-specific antigen ratio (%fPSA) in identifying prostate cancer (PCa) in men with a prostate-specific antigen (PSA) level of 2.5-3.9 ng/mL and a normal digital rectal examination (DRE). PATIENTS AND METHODS: • A prospective PCa screening study was conducted, which included 17571 men aged ≥ 45 years, across six Brazilian states, where men were recalled for further evaluation in the case of either a suspicious DRE and/or PSA ≥ 4.0 ng/mL, or PSA 2.5-3.9 ng/mL and %fPSA ≤ 15. • We evaluated the impact of a %fPSA ≤ 15 on cancer detection rates and the clinical and pathological stage of tumours in men with a normal DRE and PSA 2.5-3.9 ng/mL. RESULTS: • When suspicious DRE and/or PSA ≥ 4.0 ng/mL were considered as criteria to prompt further evaluation, the cancer detection rate was 3.1%. When %fPSA ≤ 15 in men with total PSA levels of 2.5-3.9 ng/mL were considered as criteria, the PCa detection rate increased to 3.7%. Considering %fPSA ≤ 15 in men with PSA 2.5-3.9 ng/mL and normal DRE, the positive predictive value of biopsy was 31.1%. • Clinical stage was more favourable among men with PSA 2.5-3.9 ng/mL, normal DRE, and %fPSA ≤ 15 compared with men with normal DRE and PSA ≥ 4.0 ng/mL (P= 0.02). • Among those who underwent radical prostatectomy, pathological stage and the proportion of insignificant tumours were similar between men with PSA 2.5-3.9 ng/mL, normal DRE findings and %fPSA ≤ 15, and men with PSA ≥ 4.0 ng/mL. CONCLUSIONS: • The use of %fPSA ≤ 15 as a biopsy indication in men with normal DRE and PSA 2.5-4.0 ng/mL in a PCa screening programme, increased cancer detection rates. Tumours in this subset of patients had similar pathological characteristics. • Using %fPSA ≤ 15 to indicate biopsy in men with PSA 2.5-3.9 ng/mL is a useful adjunct to PCa screening.
