Are Infertile Men Less Healthy than Fertile Men? Results of a Prospective Case-Control Survey

BACKGROUND An association between either subfertility or infertility and an elevated risk of certain male cancers has been previously reported. Nothing is known about abnormalities in infertility and general health conditions. OBJECTIVE To assess whether men with male factor infertility (MFI) are overall less healthy than fertile men, regardless of the reasons for infertility. DESIGN, SETTING, AND PARTICIPANTS From September 2006 to September 2007, 344 consecutive European Caucasian men with MFI were enrolled in this prospective case-controlled study. Patients were compared with a control group of 293 consecutive age-comparable fertile men. Infertile men were consecutively attending the outpatient male reproductive clinic at a tertiary academic center. Fertile controls were consecutively recruited by use of advertisements posted within our hospital. MEASUREMENTS Comorbidities of patients and fertile men were objectively scored with the Charlson Comorbidity Index (CCI) according to the International Classification of Diseases modified ninth version (ICD-9-CM) codes. Multivariate linear regression models tested the association between predictors and CCI score, as a proxy of general health status. RESULTS According to the CCI scores, infertile men had a significantly higher rate of comorbidities compared with the fertile controls (CCI: 0.33 [0.8] vs 0.14 [0.5]; p<0.001; 95% CI: 0.08-0.29). Linear regression analyses showed that although educational status did not have an impact on CCI (β: 0.035; p=0.365), while CCI linearly increased with age (β: 0.196; p<0.001) and body mass index (BMI; β: 0.161; p<0.001). After adjusting for age, BMI, and educational status, a significantly lower CCI was calculated for fertile men and compared with MFI patients (β: -0.199; p<0.001). CONCLUSIONS These results show that MFI accounts for a higher CCI, which may be considered a reliable proxy of a lower general health status.

Impact of Histologic Subtype on Cancer-specific Survival in Patients with Renal Cell Carcinoma and Tumor Thrombus

BACKGROUND Although different prognostic factors for patients with renal cell carcinoma (RCC) and vena cava tumor thrombus (TT) have been studied, the prognostic value of histologic subtype in these patients remains unclear. OBJECTIVE We analyzed the impact of histologic subtype on cancer-specific survival (CSS). DESIGN, SETTINGS, AND PARTICIPANTS We retrospectively analyzed the records of 1774 patients with RCC and TT who underwent radical nephrectomy and tumor thrombectomy from 1971 to 2012 at 22 US and European centers. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS Multivariable ordered logistic and Cox regression models were used to quantify the impact of tumor histology on CSS. RESULTS AND LIMITATIONS Overall 5-yr CSS was 53.4% (confidence interval [CI], 50.5-56.2) in the entire group. TT level (according to the Mayo classification of macroscopic venous invasion in RCC) was I in 38.5% of patients, II in 30.6%, III in 17.3%, and IV in 13.5%. Histologic subtypes were clear cell renal cell carcinoma (cRCC) in 89.9% of patients, papillary renal cell carcinoma (pRCC) in 8.5%, and chromophobe RCC in 1.6%. In univariable analysis, pRCC was associated with a significantly worse CSS (p<0.001) compared with cRCC. In multivariable analysis, the presence of pRCC was independently associated with CSS (hazard ratio: 1.62; CI, 1.01-2.61; p<0.05). Higher TT level, positive lymph node status, distant metastasis, and fat invasion were also independently associated with CSS. CONCLUSIONS In our multi-institutional series, we found that patients with pRCC and vena cava TT who underwent radical nephrectomy and tumor thrombectomy had significantly worse cancer-specific outcomes when compared with patients with other histologic subtypes of RCC. We confirmed that higher TT level and fat invasion were independently associated with reduced CSS.

Renal Sinus Fat Invasion in pT3a Clear Cell Renal Cell Carcinoma Affects Outcomes of Patients Without Nodal Involvement or Distant Metastases

PURPOSE According to the 2002 American Joint Committee on Cancer TNM classification, perinephric and renal sinus fat invasion are classified as pT3a renal cell carcinoma. However, only a few studies have assessed the impact of sinus fat invasion on patient survival and with controversial results. We analyzed the impact of sinus fat invasion on cancer specific survival in a cohort of patients with pT3a clear cell renal cell carcinoma. MATERIALS AND METHODS We retrospectively analyzed data on 115 consecutive patients treated with open radical nephrectomy for unilateral, sporadic pT3a clear cell renal cell carcinoma at our department from 1989 to 2006. All pathological specimens were rereviewed by a single uropathologist. The prognostic role of sinus fat invasion in cancer specific survival was assessed by Cox proportional hazards regression models. RESULTS Ten patients had direct ipsilateral adrenal invasion and were excluded from analysis. A total of 105 patients with clear cell renal cell carcinoma were evaluated. Median followup was 38 months. In the overall population sinus fat invasion did not reach independent predictive status in terms of cancer specific survival on multivariate Cox regression analysis after adjusting for age, performance status, tumor dimension, tumor grade, synchronous metastases, nodal involvement, sarcomatoid differentiation and coagulative necrosis. In the subset of patients with pNx/pN0 M0 (83) the actuarial 5-year cancer specific survival was 71.9% and 45.5% for those with perinephric fat invasion only and sinus fat invasion, respectively (p = 0.025). Sinus fat invasion achieved an independent predictive role on multivariable Cox regression analysis (p = 0.048, HR 2.06). CONCLUSIONS Sinus fat invasion in clear cell renal cell carcinoma significantly affects cancer specific survival in patients without nodal or distant metastases. However, sinus fat invasion is not associated with worse cancer specific survival in cases of metastatic disease.

Impact of Venous Tumour Thrombus Consistency (Solid vs Friable) on Cancer-specific Survival in Patients with Renal Cell Carcinoma

BACKGROUND To our knowledge, the impact of venous tumour thrombus (VTT) consistency in patients affected by renal cell carcinoma (RCC) has never been addressed. OBJECTIVE To analyse the effect of VTT consistency on cancer-specific survival (CSS). DESIGN, SETTING, AND PARTICIPANTS We retrospectively analysed 174 consecutive patients with RCC and renal vein or inferior vena cava (IVC) VTT who underwent surgical treatment between 1989 and 2007 at our institute. INTERVENTION All patients underwent radical nephrectomy and thrombectomy. MEASUREMENTS Pathologic specimens were reviewed by a single uropathologist. In addition to traditional pathologic features, the morphologic aspect of the tumour thrombus was evaluated to distinguish solid from friable patterns. The prognostic role of thrombus consistency (solid vs friable) on CSS was assessed by means of Cox regression models. RESULTS AND LIMITATIONS The VTT was solid in 107 patients (61.5%) and friable in 67 patients (38.5%). The presence of a friable VTT increased the risk of having synchronous nodal or distant metastases, higher tumour grade, higher pathologic stage, and simultaneous perinephric fat invasion (all p < 0.05). The median follow-up was 24 mo. The median CSS was 33 mo; the median CSS was 8 mo in patients with a friable VTT and 55 mo in patients with a solid VTT (p < 0.001). On multivariable analyses, the presence of a friable VTT was an independent predictor of CSS (p = 0.02). The power of our conclusion may be somewhat limited by the relatively small study population and the retrospective nature of the study. CONCLUSIONS In patients with RCC and VTT, the presence of a friable thrombus is an independent predictor of CSS. If our finding is confirmed by further studies, the consistency of the tumour thrombus should be introduced into routine pathologic reports to provide better patient risk stratification.

Impact of Synchronous Metastasis Distribution on Cancer Specific Survival in Renal Cell Carcinoma after Radical Nephrectomy with Tumor Thrombectomy

PURPOSE Metastatic renal cell carcinoma can be clinically diverse in terms of the pattern of metastatic disease and response to treatment. We studied the impact of metastasis and location on cancer specific survival. MATERIALS AND METHODS The records of 2,017 patients with renal cell cancer and tumor thrombus who underwent radical nephrectomy and tumor thrombectomy from 1971 to 2012 at 22 centers in the United States and Europe were analyzed. Number and location of synchronous metastases were compared with respect to patient cancer specific survival. Multivariable Cox regression models were used to quantify the impact of covariates. RESULTS Lymph node metastasis (155) or distant metastasis (725) was present in 880 (44%) patients. Of the patients with distant disease 385 (53%) had an isolated metastasis. The 5-year cancer specific survival was 51.3% (95% CI 48.6-53.9) for the entire group. On univariable analysis patients with isolated lymph node metastasis had a significantly worse cancer specific survival than those with a solitary distant metastasis. The location of distant metastasis did not have any significant effect on cancer specific survival. On multivariable analysis the presence of lymph node metastasis, isolated distant metastasis and multiple distant metastases were independently associated with cancer specific survival. Moreover higher tumor thrombus level, papillary histology and the use of postoperative systemic therapy were independently associated with worse cancer specific survival. CONCLUSIONS In our multi-institutional series of patients with renal cell cancer who underwent radical nephrectomy and tumor thrombectomy, almost half of the patients had synchronous lymph node or distant organ metastasis. Survival was superior in patients with solitary distant metastasis compared to isolated lymph node disease.

Delay in Seeking Medical Help in Patients with New‐Onset Erectile Dysfunction Remained High Over and Despite the PDE5 Era—An Ecological Study

INTRODUCTION It is common knowledge among researchers that erectile dysfunction (ED) is an important sentinel marker of cardiovascular and overall mens health. AIM Determine whether the delay of time between ED onset and seeking medical help (DSH), considered as a proxy of awareness of the importance of ED for overall mens health, has shortened during the phosphodiesterase type 5 inhibitors (PDE5) era. METHODS Complete data from 619 patients seeking first medical help for new-onset ED as their primary disorder between July 2000 and July 2010 were analyzed (i.e., DSH, ED severity as defined by the International Index of Erectile Function-erectile function [IIEF-EF] domain score, patients awareness of any PDE5, and Charlson Comorbidity Index [CCI]). Analysis of variance tested DSH throughout the 10-year time frame. Cox regression models tested the association between predictors and DSH. MAIN OUTCOME MEASURES Assess if DSH has shortened throughout PDE5 era. Evaluate potential predictors of DSH. RESULTS Overall, mean DSH was 30.2 months (median 12.0; range 5-300 months). DSH shortened throughout the analyzed 10-year period (F = 1.918; P = 0.047), with a significant drop only from year 2009 (DSH up to year 2008 vs. from year 2009: 31.0 months [12.0] vs. 7.5 months [6.0], respectively; P < 0.001). Age, CCI, educational status, and ED severity did not significantly change over time. As a whole, 560 patients (90.5%) were aware of PDE5 at the time of their first office visit. PDE5 awareness emerged as an univarible and multivariable predictor of a shortened DSH. Conversely, DSH was not clearly associated with age, CCI, educational status, or ED severity. CONCLUSIONS Delay in seeking medical help in new-onset ED patients remained high over the PDE5 era, with a significant drop only from the year 2009. PDE5 awareness emerged as an independent predictor of shortening of this delay.

Is sperm banking of interest to patients with nongerm cell urological cancer before potentially fertility damaging treatments

PURPOSE We assessed the opinions of patients with nongerm cell urological cancer on sperm banking before undergoing surgical or nonsurgical therapy that could potentially endanger subsequent fertility. MATERIALS AND METHODS Between April 2007 and July 2008, 753 patients visited a urological office and were invited to complete a brief self-administered questionnaire to assess opinions on sperm banking before undergoing any eventual therapy potentially dangerous for male fertility. Logistic regression models tested the association between predictors (age, educational level, relationship status, previous fatherhood and benign disorder vs nongerm cell urological cancer) and patient wishes for sperm banking. RESULTS Median patient age was 65 years (mean 61.6, range 18 to 76). Overall 522 patients (69.3%) had nongerm cell urological cancer and only 242 (32.1%) were in favor of pretreatment sperm banking. On univariate analysis age (OR 0.961, p <0.001), a stable relationship (OR 0.486, p <0.001) and previous fatherhood (OR 0.390, p <0.001) were inversely associated with the wish for sperm banking, whereas having cancer and educational status were not significantly correlated. Multivariate analysis indicated that aging (OR 0.966, p = 0.001) and previous fatherhood (OR 0.587, p = 0.029) maintained inverse associations. Having urological cancer was positively (OR 1.494, p = 0.045) associated with the wish for sperm banking. CONCLUSIONS In urological patients there is a low rate of willingness to bank sperm before any potential fertility damaging therapeutic approach. Having nongerm cell urological cancer is an independent predictor that is positively associated with the wish to bank sperm. It is vitally important to provide comprehensive information about pretreatment sperm banking to young adults with nongerm cell urological cancer.
