RESUMEN
INTRODUCTION: Incisional and parastomal hernias are frequent complications after cystectomy. The aim of our study was to define their incidence, identify risk factors related to the patient and the surgical technique, and identify means of prevention. MATERIAL: This was a multicenter, retrospective study, analyzing clinical and radiological data from 521 patients operated on for cystectomy between January 2010 and December 2020. RESULTS: In total, 521 patients, 471 men and 50 women, mean age 68.8years, were included. Thirty-one patients (6.6%) presented with an evisceration. Risk factors were a history of evisceration (OR: 14.1; 95% CI: [3-66]; P=0.0008), COPD (OR: 3.5; 95% CI: [1.3-9 .4]; P=0.0119), ischemic heart disease (OR: 4; 95% CI: [1. 6-10]; P=0.0036), and split-stitch closure (OR: 3.1; 95% CI: [1.065-8.9]; P=0.0493). Fifty-one patients (9.9%) presented with an incisional hernia. Risk factors were a history of COPD (OR: 4, 95% CI: [2.1-7.6]; P<0.001) and postoperative pulmonary infection (OR: 5.3; 95% CI: [1.05-26.4]; P=0.0079). Seventy-nine patients (15.28%) had a parastomal hernia. Overweight was a risk factor (OR: 2.3; 95% CI: [1.3-4.5]; P=0.0073). CONCLUSION: Patients who are overweight or have pulmonary comorbidities are at greater risk of developing parietal complications after cystectomy. LEVEL OF EVIDENCE: III.

Systematic screening for prostate cancer is widely recommended in candidates for renal transplant at the time of listing. There are concerns that overdiagnosis of low-risk prostate cancer may result in reducing access to transplant without demonstrated oncological benefits. The objective of the study was to assess the outcome of newly diagnosed prostate cancer in candidates for transplant at the time of listing, and its impact on transplant access and transplant outcomes according to treatment options. This retrospective study was conducted over 10 years in 12 French transplant centers. Patients included were candidates for renal transplant at the time of prostate cancer diagnosis. Demographical and clinical data regarding renal disease, prostate cancer, and transplant surgery were collected. The primary outcome of the study was the interval between prostate cancer diagnosis and active listing according to treatment options. Overall median time from prostate cancer diagnosis to active listing was 25.0 months [16.4-40.2], with statistically significant differences in median time between the radiotherapy and the active surveillance groups (p = .03). Prostate cancer treatment modalities had limited impact on access and outcome of renal transplantation. Active surveillance in low-risk patients does not seem to compromise access to renal transplantation, nor does it impact oncological outcomes.

OBJECTIVE: To analyze de novo graft carcinoma characteristics from our updated national multicentric retrospective cohort. METHODS: Thirty-two transplant centers have retrospectively completed the database. This database concerns all kidney graft tumors including urothelial, and others type but excludes renal lymphomas over 31 years. RESULTS: One hundred and fifty twokidney graft carcinomas were diagnosed in functional grafts. Among them 130 tumors were Renal Cell Carcinomas. The calculated incidence was 0.18%. Median age of the allograft at diagnosis was 45.4 years old. The median time between transplantation and diagnosis was 147.1 months. 60 tumors were papillary carcinomas and 64 were clear cell carcinomas. Median tumor size was 25 mm. 18, 64, 21 and 1 tumors were respectively Fuhrman grade 1, 2, 3 and 4. Nephron sparing surgery (NSS) was performed on 68 (52.3%) recipients. Ablative therapy was performed in 23 cases (17.7%). Specific survival rate was 96.8%. CONCLUSION: This study confirmed that renal graft carcinomas are a different entity: with a younger age of diagnosis; a lower stage at diagnosis; a higher incidence of papillary subtypes.

BACKGROUND: Data are limited on prostate cancer (PC) management in patients with haemophilia (PWH). AIM: To describe PC screening and diagnosis, treatment modalities and bleeding complications in a group of unselected PWH followed at French Haemophilia Treatment Centres (HTCs) PATIENTS AND METHODS: PC screening, management and bleeding complications were retrospectively investigated at 14 French HTCs between 2003 and 2018. RESULTS: Among> 1549 > 50-year-old PWHs, 73 (4.7%) underwent PC screening (median age 71.1 years; 67/6â¯HA/HB, 17/56 severe-moderate/mild). At diagnosis, haematuria was infrequent. Prophylaxis was administered during 76/86 (88%) prostate biopsies (PB) (n = 67 clotting factor concentrates, CFC; n = 9 desmopressin; n = 17 associated with tranexamic acid, TA). Bleeding (11/86, 12.8%) occurred mainly post-prophylaxis (median delay: 7 days): haematuria (9/11, 81.8%), and rectal bleeding (2/11, 18.2%) including one major (1.2%). PC was confirmed in 50/86 PB and in two prostatectomy specimens (total n = 50 patients, n = 6 with only active surveillance). Surgery (n = 28/44 patients) was managed with CFC. Fifteen patients had radiotherapy/brachytherapy, 10â¯had hormone therapy; CFC-based prophylaxis was only prescribed for brachytherapy (n = 2). Major bleedings occurred in 3/28 (10.7%) and 2/15 (13.3%) patients who underwent surgery and radio/brachytherapy, respectively. No bleeding risk factor was found. CONCLUSION: Our data indicate that PB requires prophylaxis for atleast 7 days, using CFC, desmopressin or TA in function of haemophilia severity. PC surgery should be considered at high bleeding risk. Long-term post-procedural CFC or oral TA could be discussed. Radiotherapy/brachytherapy also should be managed with prophylaxis (CFC or TA).

BACKGROUND AND AIM: Incisional hernia (IH) after Kidney Transplantation (KT) is a challenging complication due to both technical reasons and patients' complexity. Data regarding outcomes of hernia repair in KT recipients are uncertain, since the biggest part of previous papers focused on risk factors for incisional hernia occurrence and not on its outcomes. Aim of the study was to focus on risk factors for incisional hernia recurrence after surgical repair in KT recipients. METHODS: Data regarding all consecutive patients undergoing kidney transplantations from January 2011 until September 2020 in Montpellier University Hospital were retrospectively collected from a single institutional database. RESULTS: After a median follow-up of 48 months (IQR25-75 31-59), data from 1546 consecutive KT were collected. 83 patients underwent 99 incisional hernia surgeries after KT, with 14 patients that had one recurrence (14.4%) and 2 patients that experienced two recurrences (2.4%). Total recurrence rate was 16.8%. At univariate analysis, the only factor associated with an incisional hernia recurrence was having undergone to at least one previous abdominal surgery other than KT (p value 0.002). Overall morbidity was 15% (n = 15), with most of complications classified as mild (59%). No mortality related to incisional hernia repair occurred. CONCLUSION: IHs after KT represent an important condition. Its surgical management is challenging due to its anatomical complexity and patient's status. This is the largest sample size in the literature of patients treated for IH after KT and it shows that a previous surgery other than the KT is a risk factor for hernia recurrence after surgical repair, without regarding surgical technique or other comorbidity and therapeutical factors.

OBJECTIVE: Compare different imaging scenarios in the diagnosis of uncomplicated renal colic due to urolithiasis (URCU). MATERIALS AND METHODS: A total of 206 prospectively included patients had been admitted with suspected URCU and had undergone abdominal plain film (APF), US and unenhanced CT after clinical STONE score evaluation. CT was the reference standard. We assessed sensitivity (Se), specificity (Spe) and Youden index for colic pain diagnosis, percentage of patients managed by urologic treatment with stone identified, percentage of alternative diagnoses (AD) and exposure to radiation, according to single imaging approaches, strategies driven by patient characteristics and conditional imaging strategies after APF and US. RESULTS: One hundred (48.5%) patients had a final diagnosis of URCU and 19 underwent urologic treatment. The conditional strategy, i.e. CT in patients who had no stone identified at US, had a perfect sensitivity and specificity. This enabled diagnosis of all stones requiring urology management while decreasing the number of CT exams by 22%. The strategy whereby CT was used when there was neither direct or indirect APF + US finding of colic pain nor alternative diagnoses in patients with a STONE score ≥ 10 had a sensitivity of 0.95 and a specificity of 0.99, identified 84% of stones managed by urologic treatment and decreased the number of CT examinations by 76%. CONCLUSION: In patients with clinical findings consistent with URCU, the use of ultrasound as first-line imaging modality, with CT restricted to patients with negative US and a STONE score ≥ 10, led to a sensitivity and specificity of above 95%, identified 84% of stones requiring urological management and reduced the number of CT scans needed by fourfold. KEY POINTS: ⢠For diagnosis, the use of APF + US as first-line imaging, with CT restricted to patients with both a normal APF + US and a STONE score ≥ 10, provides both a sensitivity and specificity superior or equal to 95% and reduces the number of CT scans necessary by fourfold. ⢠For management, the use of APF + US as first-line imaging, with CT restricted to patients with both a normal APF + US and a STONE score ≥ 10, maintains a 84% stone identification rate in urology-treated patients.

PURPOSE: The objective of this study was to compare living-donor kidney transplantation (LDKT) performed either sequentially, in one operating room, leading to extended cold ischemia time (CIT) or simultaneously, in two different operating room, with shorter CIT. METHODS: We retrospectively included all living-donor nephrectomies and kidney transplantations, performed from March 2010 to March 2014, in three French university centers. In the first one (C1), LDKTs were performed in sequential manner (Sequential group) and in C2 and C3, LDKTs were performed in simultaneous manner (Simultaneous group). RESULTS: A total of 324 LDKT were performed: 176 LDKT in Sequential group and 148 LDKT in Simultaneous group. Patients characteristics were equivalent between groups, except nephrectomy side, ABO mismatch rate and previous kidney transplantation rate. CIT, rewarming time, transfusion and delayed graft function (DGF) were significantly higher in Sequential group. Overall survival and graft survival of kidney transplant recipients were similar in the Sequential and Simultaneous groups. 5-year eGFR was similar between groups. In univariate analysis, number of graft arteries, recipient BMI, previous kidney transplantation status and CIT were significant predictors of DGF. Only previous kidney transplantation status was an independent predictive factor of DGF in the multivariate analysis. CONCLUSIONS: Sequential surgical organization results in the same functional results as simultaneous surgical organization. DGF was higher for LDKT performed sequentially but at 5-year overall survival, graft survival and eGFR were similar between these two types of transplant organizations.

BACKGROUND: Renal insufficiency can occur in patients with congenital lower urinary tract malformations (LUTM) even when managed during infancy. Data in the current literature concerning this subject remain sparse. The aim of this study was to report the feasibility and long-term results of renal transplantation during adulthood in patients with a congenital LUTM. METHODS: A retrospective multicenter study from 3 French renal transplant centers was conducted, including 123 transplantations on 112 patients with LUTM (1996-2016). Graft survival, patient survival, and complications were analyzed. Results were stratified according to the underlying uropathy and the type of initial management during childhood or before transplantation. RESULTS: In this study, patients suffering from posterior urethral valves (n = 49), spina bifida (n = 21), central neurogenic bladder (n = 13), bladder exstrophy (n = 14), prune belly syndrome (n = 12), Hinman syndrome (n = 6), urogenital sinus (n = 4), and other pathologies (n = 4) were included. The mean age at transplantation was 32.1 years old (±11.2). The mean follow-up period was 7.2 years. Patient survival at 1, 5, 10, and 15 years was 97.4%, 93.0%, 89.4%, and 80.0%, respectively. Graft survival at 1, 5, 10, 15, and 20 years was 96.6%, 87.6%, 77.3%, 60.6%, and 36.4%, respectively. Enterocystoplasty and continent urinary diversions exposed grafts to more frequent acute pyelonephritis (P = 0.02). There was no difference in graft survival when transplantation was performed on an enterocystoplasty or urinary diversions compared with a native bladder, provided a well-conducted bladder management. CONCLUSIONS: Even though enterocystoplasty and continent urinary diversions exposed grafts to more frequent acute graft pyelonephritis, patient and graft survival rates in LUTM at 10 years were similar to other kidney transplantations on native bladders.

The investigation of an outbreak of Pseudomonas aeruginosa urinary tract infections after ambulatory cystoscopies identified a damaged cystoscope contaminated by P aeruginosa and acting as a relay object. This outbreak urges us not to trivialize urinary tract infections occurring after an elective cystoscopy. Patients should be advised to signal the occurrence of urologic symptoms after urologic exploration.

Epidemiological studies have suggested that prostatitis may increase the risk of prostate cancer due to chronic inflammation. We studied the association between several genitourinary infections and the risk of prostate cancer based on data from the EPICAP study. EPICAP is a population-based case-control study conducted in the département of Hérault, France, between 2012 and 2014. A total of 819 incident cases and 879 controls have been face to face interviewed using a standardized questionnaire gathering information on known or suspected risk factors of prostate cancer, and personal history of genitourinary infections: prostatitis, urethritis, orchi-epididymitis, and acute pyelonephritis. Odds Ratios (OR) and their 95% confidence interval were estimated using multivariate unconditional logistic regression. Overall, 139 (18%) cases and 98 (12%) controls reported having at least one personal history of genitourinary infections (OR = 1.64 [1.23-2.20]). The risk increased with the number of infections (p-trend < 0.05). The association was specifically observed with personal history of chronic prostatitis and acute pyelonephritis (OR = 2.95 [1.26-6.92] and OR = 2.66 [1.29-5.51], respectively) and in men who did not use any non-steroidal anti-inflammatory drugs (OR = 2.00 [1.37-2.91]). Our results reinforce the hypothesis that chronic inflammation, generated by a personal history of genitourinary infections, may play a role in prostate carcinogenesis.

Although renal graft percutaneous embolization was introduced to avoid the risk associated with graft nephrectomy, there is no universal consensus about its indications and results. In order to evaluate the efficacy of graft embolization in the treatment of graft intolerance syndrome as well as its safety compared to surgical removal with respect to complications and other morbidity measures, We performed a retrospective observational study comparing two groups of patients treated for graft intolerance syndrome: Group 1: patients who had embolization as first-line treatment and Group 2: patients directly treated by surgical removal. 72 patients were included, (32 in Group 1 and 40 in Group 2); the postintervention follow-up continued for 12 months. Patients in Group 1 are older than those in Group 2. Otherwise, the two groups are similar concerning sex, manifestations of graft intolerance syndrome, diabetes and nutritional and functional status. The overall success rate of embolization in complete resolution of graft intolerance syndrome and ultimately avoidance of surgical removal was 84.37%. The surgical removal group had more serious complications, a longer hospital stay and needed more blood transfusions. We conclude that embolization of symptomatic renal grafts has considerable efficacy with less morbidity, and no serious complications compared to the standard surgical graft removal.

BACKGROUND: Extracorporeal membranous oxygenation is proposed for abdominal organ procurement from donation after circulatory determination of death (DCD). In France, the national Agency of Biomedicine supervises the procurement of kidneys from DCD, specifying the durations of tolerated warm and cold ischemia. However, no study has determined the optimal conditions of this technique. The aim of this work was to develop a preclinical model of DCD using abdominal normothermic oxygenated recirculation (ANOR). In short, our objectives are to characterize the mechanisms involved during ANOR and its impact on abdominal organs. METHODS: We used Large White pigs weighing between 45 and 55 kg. After 30 minutes of potassium-induced cardiac arrest, the descending thoracic aorta was clamped and ANOR set up between the inferior vena cava and the abdominal aorta for 4 hours. Hemodynamic, respiratory and biochemical parameters were collected. Blood gasometry and biochemistry analysis were performed during the ANOR procedure. RESULTS: Six ANOR procedures were performed. The surgical procedure is described and intraoperative parameters and biological data are presented. Pump flow rates were between 2.5 and 3 l/min. Hemodynamic, respiratory, and biochemical objectives were achieved under reproducible conditions. Interestingly, animals remained hemodynamically stable following the targeted protocol. Arterial pH was controlled, and natremia and renal function remained stable 4 hours after the procedure was started. Decreased hemoglobin and serum proteins levels, concomitant with increased lactate dehydrogenase activity, were observed as a consequence of the surgery. The serum potassium level was increased, owing to the extracorporeal circulation circuit. CONCLUSIONS: Our ANOR model is the closest to clinical conditions reported in the literature and will allow the study of the systemic and abdominal organ impact of this technique. The translational relevance of the pig will permit the determination of new biomarkers and protocols to improve DCD donor management.
RESUMEN
Numerous therapeutic options are possible in the treatment of renal carcinomas including radical nephrectomy, partial nephrectomy, cryoablation, radiofrequency, active follow-up and among surgical treatments, different approaches may be used such as laparotomy, laparoscopy, robotic-assisted intervention. The choice between these different procedures is partially based on the anatomic conditions of the tumors. Different anatomic scores determined from cross-sectional imaging have been built to predict the complexity of the surgical procedure. The goals of this article are to review the relevant morphologic pattern for management of patients with renal tumors, to know how to calculate these different scores and to understand the clinical applications of these scores.

OBJECTIVES: To determine the impact of renal graft nephrectomy on second kidney transplantation survival. METHODS: We carried out a retrospective single-center study by analyzing cases performed from January 2000 to December 2011. Retransplanted patients who underwent previous allograft nephrectomy more than 3 months post-transplantation (group 1) were compared with those who did not (group 2) in terms of graft survival, incidences of acute rejection and delayed graft function. Multivariate Cox proportional hazard models were used to assess risk factors of graft loss after retransplantation. RESULTS: Overall, 146 patients were analyzed, including 52 (35.6%) in group 1 and 94 (64.4%) in group 2. Group 1 patients presented a significantly shorter first graft survival (0.8 vs 8.6 years, P < 0.001) and more anti-class I antibodies (90.5% vs 74.2%, P = 0.03). A total of 10 patients (19%) in group 1 and 16 patients (17%) in group 2 had at least one acute rejection episode (P = 0.74). Delayed graft function was observed in 13 patients (25%) in group 1 and 17 patients (18%) in group 2 (P = 0.32). Graft survival at 1, 5 and 10 years was, respectively, 94%, 81% and 58% in group 1, and 99%, 93% and 66% in group 2 (P = 0.10). Graft survival was decreased by increased donor age and serum creatinine, and tended to be associated with post-transplantation presence of anti-class I and II antibodies. Graft nephrectomy was not associated with graft survival in multivariate analysis. CONCLUSIONS: Graft nephrectomy, probably a marker of high immunological risk patients, is not a risk factor of increased retransplant failure.

BACKGROUND: Prostate cancer is the most common cancer in male in most Western countries, including France. Despite a significant morbidity and mortality to a lesser extent, the etiology of prostate cancer remains largely unknown. Indeed, the only well-established risk factors to date are age, ethnicity and a family history of prostate cancer. We present, here, the rationale and design of the EPIdemiological study of Prostate CAncer (EPICAP), a population-based case-control study specifically designed to investigate the role of environmental and genetic factors in prostate cancer. The EPICAP study will particularly focused on the role of circadian disruption, chronic inflammation, hormonal and metabolic factors in the occurrence of prostate cancer. METHODS/DESIGN: EPICAP is a population-based case-control study conducted in the département of Hérault in France. Eligible cases are all cases of prostate cancers newly diagnosed in 2012-2013 in men less than 75 years old and residing in the département of Hérault at the time of diagnosis. Controls are men of the same age as the cases and living in the département of Hérault, recruited in the general population.The sample will include a total of 1000 incident cases of prostate cancer and 1000 population-based controls over a 3-year period (2012-2014).The cases and controls are face-to-face interviewed using a standardized computed assisted questionnaire. The questions focus primarily on usual socio-demographic characteristics, personal and family medical history, lifestyle, leisure activities, residential and occupational history. Anthropometric measures and biological samples are also collected for cases and controls. DISCUSSION: The EPICAP study aims to answer key questions in prostate cancer etiology: (1) role of circadian disruption through the study of working hours, chronotype and duration/quality of sleep, (2) role of chronic inflammation and anti-inflammatory drugs, (3) role of hormonal and metabolic factors through a detailed questionnaire, (4) role of individual genetic susceptibility of genes involved in biological pathways of interest. The EPICAP study will also allow us to study prognostic factors and tumor aggressiveness.Taken together, the EPICAP study will provide a comprehensive framework to go further in the understanding of prostate cancer occurrence and its prognosis.

PURPOSE: Concomitant treatment with radiation therapy and cisplatin (CDDP) remains the gold standard for bladder preservation in the treatment of muscle-invasive bladder cancer (MIBC). We present the long-term results of a phase 1 clinical trial to assess the association of twice-weekly gemcitabine with CDDP and radiation therapy in this setting. METHODS AND MATERIALS: Patients with pT2-pT4N0M0 MIBC without hydronephrosis or diffuse carcinoma in situ were enrolled in this study. After maximal transurethral resection of the bladder tumor, patients received concomitant radiation therapy (63 Gy in 1.8 fractions) and chemotherapy (CDDP 20 mg/m²/day over 4 days every 21 days and gemcitabine twice a week). The starting dose of gemcitabine was 15 mg/m² with dose escalation to 20, 25, and 30 mg/m². The primary endpoint was the maximum tolerated dose (MTD). Secondary endpoints included toxicity and tumor control. RESULTS: Fourteen patients were enrolled. Dose-limiting toxicity occurred in 2 patients treated with 30 mg/m² gemcitabine (grade 4 thrombocytopenia and severe impairment of World Health Organization performance status, respectively). Nine patients received the complete chemoradiation therapy protocol. The recommended dose of gemcitabine was 25 mg/m². The median follow-up time was 53 months, and the overall and disease-specific 5-year survival rates were 62% and 77%, respectively. Among the patients who received the complete treatment, bladder-intact survival was 76% at 5 years, and the median overall survival was 69.6 months. CONCLUSIONS: This regimen was well tolerated. The gemcitabine MTD was 25 mg/m². Bladder preservation and disease control were promising. A multicenter phase 2 randomized trial is ongoing.

PURPOSE: The present study assessed the incidence and histopathological features of incidentally diagnosed prostate cancer (PCa) in specimens from radical cystoprostatectomy (RCP) for bladder cancer. The patient outcomes also were evaluated. METHODS: We retrospectively reviewed the histopathological features and survival data of 4,299 male patients who underwent a RCP for bladder cancer at 25 French centers between January 1996 and June 2012. No patients had preoperative clinical or biological suspicion of PCa. RESULTS: Among the 4,299 RCP specimens, PCa was diagnosed in 931 patients (21.7%). Most tumors (90.1%) were organ-confined (pT2), whereas 9.9% of them were diagnosed at a locally advanced stage (≥pT3). Gleason score was <6 in 129 cases (13.9%), 6 in 575 cases (61.7%), 7 (3 + 4) in 149 cases (16.0%), 7 (4 + 3) in 38 cases (4.1%), and >7 in 40 cases (4.3%). After a median follow-up of 25.5 months (interquartile range 14.2-47.4), 35.4% of patients had bladder cancer recurrence and 23.8% died of bladder cancer. Only 16 patients (1.9%) experienced PCa biochemical recurrence during follow-up, and no preoperative predictive factor was identified. No patients died from PCa. CONCLUSIONS: The rate of incidentally diagnosed PCa in RCP specimens was 21.7%. The majority of these PCas were organ-confined. PCa recurrence occurred in only 1.9% of cases during follow-up.

BACKGROUND: Local recurrence (LR) after radical nephrectomy (RN) for kidney cancer is uncommon. Our objectives were to analyse characteristics and therapeutic options of LR after RN and to identify survival prognostic factors. MATERIALS AND METHODS: From a multi-institutional retrospective database, we identified 72 patients who experienced LR after RN. RESULTS: Mean time to LR was 26.5 ± 3.3 months. The location of the recurrence was renal fossa, regional lymph node, homolateral adrenal and both renal fossa and regional lymph node for 43 (59.7%), 27 (37.5%), 9 (12.5%) and 7 (9.7%) patients, respectively. Patients were treated by surgery, systemic therapies, combination of therapies and palliative treatment in 24 (33.3%), 18 (25%), 24 (33.3%) and 6 (8.4%) cases, respectively. Within a mean follow-up of 26.4 ± 3.3 months from the date of local recurrence, 12 (16.6%) patients were alive without disease, 30 (41.7%) patients were alive with disease, 30 patients (41.6%) died including 28 (38.8%) from the disease. In multivariate analysis, time to recurrence <1 year (P < 0.001; HR: 4.81) and surgical treatment (P = 0.027; HR: 0.33) were predictive factors. CONCLUSIONS: Local recurrence after radical nephrectomy is associated with poor prognosis. The time to recurrence and the completeness of the surgical treatment are major prognostic factors.

PURPOSE: To examine the overall and stage-specific age-adjusted incidence, 5-year survival and mortality rates of bladder cancer (BCa) in the United States, between 1973 and 2009. MATERIALS AND METHODS: A total of 148,315 BCa patients were identified in the Surveillance, Epidemiology and End Results database, between years 1973 and 2009. Incidence, mortality, and 5-year cancer-specific survival rates were calculated. Temporal trends were quantified using the estimated annual percentage change (EAPC) and linear regression models. All analyses were stratified according to disease stage, and further examined according to sex, race, and age groups. RESULTS: Incidence rate of BCa increased from 21.0 to 25.5/100,000 person-years between 1973 and 2009. Stage-specific analyses revealed an increase incidence for localized stage: 15.4-20.2 (EAPC: +0.5%, p < 0.001) and distant stage: 0.5-0.8 (EAPC: +0.7%, p = 0.001). Stage-specific 5-year survival rates increased for all stages, except for distant disease. No significant changes in mortality were recorded among localized (EAPC: -0.2%, p = 0.1) and regional stage (EAPC: -0.1%, p = 0.5). An increase in mortality rates was observed among distant stage (EAPC: +1.0%, p = 0.005). Significant variations in incidence and mortality were recorded when estimates were stratified according to sex, race, and age groups. DISCUSSION: Albeit statistically significant, virtually all changes in incidence and mortality were minor, and hardly of any clinical importance. Little or no change in BCa cancer control outcomes has been achieved during the study period.

OBJECTIVE: To quantify and compare cancer-specific mortality (CSM) and other-cause mortality (OCM) in individuals with stage T1G1-3 clinically node-negative (cN0) squamous cell carcinoma of the penis (SCCP) since there is no consensus regarding the need for an inguinal lymph node dissection (ILND) in patients with T1G2-3 cN0 SCCP. METHODS: Relying on the Surveillance, Epidemiology and End Results database, we identified 655 patients diagnosed with primary SCCP between 1988 and 2006. Cumulative incidence plots were used to graphically depict the effect of CSM relative to OCM. Competing-risks regression analyses were used to quantify the risk of CSM or OCM after adjusting for age, race, tumour grade and surgery type. RESULTS: The 5-year CSM rates after a primary tumour excision without ILND were 2.6%, 10.0% and 15.9% in patients with respectively T1G1, T1G2 and T1G3 cN0 SCCP. The 5-year OCM rates were 29.5%, 27.3% and 29.3% in patients with respectively T1G1, T1G2 and T1G3. Age failed to provide additional stratification. CONCLUSIONS: The CSM rate was highest in T1G3 patients and appears to justify ILND. Conversely, the CSM rate was lowest in T1G1 patients, which justifies active surveillance in this patient subset. A moderate CSM rate at 5 years was recorded for T1G2 patients, which brings into question the benefits of ILND.
