Surgical metastasectomy for metastatic renal cell carcinoma in the era of targeted and immune therapy: a narrative review.

PURPOSE: Metastatic renal cell carcinoma (mRCC) still harbours a big propensity for future metastasis. Combinations of immune and targeted therapies are currently the cornerstone of management with a less clear role for surgical metastasectomy (SM). METHODS: We performed a narrative review of literature searching for the available evidence on the yield of surgical metastasectomy in the era of targeted and immune therapies. The review consisted of a PubMed search of relevant articles using the Mesh terms:" renal cell carcinoma", "surgery¼, «resection", "metastasectomy", "molecular targeted therapies", "immune checkpoint inhibitors" alone or in combination. RESULTS: In this review, we exposed the place of surgical metastasectomy within a multimodal treatment algorithm for mRCC Also, we detailed the patient selection criteria that yielded the best results when SM was performed. Finally, we discussed the feasibility and advantages of SM per organ site. CONCLUSION: Our work was able to show that SM could be proposed as a consolidation treatment to excise residual lesions that were deemed unresectable prior to a combination of systemic therapies. Contrastingly, it can be proposed as an upfront treatment, leaving systemic therapies as an alternative in case of future relapse. However, patient selection regarding their performance status, metastatic sites, number of lesions and tumorous characteristics is of paramount importance.

Is pudendal nerve entrapment a potential cause for weak ejaculation?

Ejaculatory dysfunction is one of the most common complaints of patients with sexual disorders. While it encompasses several ejaculatory disorders, weak ejaculation is seldom described in the literature. Since the pudendal nerve is the main nerve of ejaculation, we aim to hypothesize that pudendal nerve entrapment could be a cause of weak ejaculation, and that pudendal nerve release could contribute to the improvement of the ejaculatory stream. We presented two cases suffering from a weak ejaculatory stream and sensation of incomplete semen emptying, accompanied with clinical features of pudendal nerve entrapment. Both cases improved after pudendal nerve block and then laparoscopic transperitoneal pudendal release, with a sustained amelioration of the ejaculatory stream after 3 weeks of surgery. Pudendal canal entrapment is therefore a potentially curable cause for weak ejaculation.

Urothelial carcinoma in COVID-19: lessons from a pandemic and their impact on clinical practice.

The COVID-19 pandemic has modified the management of urothelial carcinoma (UC). Eighteen months after the onset of the pandemic, a scoping narrative review was able to state that radical cystectomy for UC should not be delayed beyond 10 weeks when neoadjuvant chemotherapy (NAC) was administered and 12 weeks when it was not. NAC should be considered when imminent chemotherapy cannot be performed. Early cystectomy should not be delayed when indicated for patients with high-risk non-MIBC. Patients with non-MIBC should still receive their induction doses of intravesical instillations. Diagnostic cystoscopy should not be deferred in symptomatic patients. Surgical management of upper tract urothelial carcinoma (UTUC) allows for a wider deferral interval.

Early penile-only metastasis of urothelial bladder carcinoma.

Penile metastasis rarely occurs as a unique and early distant recurrence of urothelial bladder carcinoma. A 77-year-old male underwent a radical cystoprostatecomy for a pT3a urothelial bladder cancer. Preoperative imaging workup concluded to a disease confined to the bladder. The patient consulted 5 months later for a penile induration. Computed tomography imaging revealed a suspicious penile nodule with no other nodal or visceral lesion. Total penectomy after a confirmatory biopsy confirmed the infiltration of the corpora cavernosa, the corpus spongiosum and the urethra by a urothelial metastasis of bladder cancer. Distant recurrences after radical surgery for locally advanced bladder cancer may occur as a unique early metastasis located to the penis.

Comparative prostate MRI before and after chronic granulomatous prostatitis following intravesical bacillus Calmette-Guérin therapy.

BACKGROUND: Granulomatous prostatitis (GnP) is an interesting complication of bacillus Calmette-Guérin (BCG) therapy as it mimics prostate cancer on clinical, biochemical and imaging examinations. In the era of multiparametric prostate MRI (mpMRI), differentiation of GnP from prostate cancer on imaging is essential. CASE PRESENTATION: We report a case of post-BCG GnP in a patient with nonmuscle invasive bladder cancer, presenting with a prostate-specific antigen level of 21.6 ng/ml and prostate imaging reporting and data system (PI-RADS) 5 peripheral lesions. A mpMRI performed 6 months before showed a score 2 of PI-RADS. CONCLUSION: The comparison of mpMRI images before and after BCG administration gives urologists, oncologists and radiologists a precise idea of the mpMRI changes that occur following BCG administration to eventually prevent unnecessary biopsies in future patients.

Discrepancies among different tools evaluating Mediterranean diet adherence during pregnancy, correlated to maternal anthropometric, dietary and biochemical characteristics.

BACKGROUND & AIMS: Scientific evidence confirms the favorable impact of Mediterranean diets (MD) on maternal and neonatal outcomes. However, the assessment of this dietary pattern requires valid indexes with scoring systems adapted to pregnant females. The aim of this cross-sectional study was to compare the adherence to MD, through 5 internationally validated tools, in pregnant women following a Mediterranean eating pattern, correlated to maternal anthropometric, dietary and biochemical markers. METHODS: 100 healthy pregnant females completed a sociodemographic questionnaire, a dietary recall and a food frequency questionnaire compatible with the MD. 10 ml of maternal blood were drawn for the analysis of biological markers such as C-reactive protein (CRP), leptin and adiponectin. RESULTS: We used the 50th percentile as cut-off of each scale (low or high adherence) to avoid the discrepancies noted in the literature among the large range of cut-offs points for the different tools. The % of agreement was high between the Mediterranean Food Pattern, MD Score, the MD Score and the Short MD Questionnaire. The MD Scale presented small agreement in relation to the other tested tools. All the tested indexes were significantly correlated with CRP levels, except for the MDScale. Significant correlations were reached regarding adiponectin and the MFP (p value = 0.04) and the MDScale (p value 0.03) tools. Pre-gestational body mass index was significantly correlated with all the tested biological markers. Significant correlations were seen between CRP on one hand and maternal age (p value = 0.033), adiponectin (p value = 0.028), and leptin (p value = 0.003) on the other. Fiber intake was significantly and negatively correlated to CRP (p value = 0.008) and positively to adiponectin levels (p value = 0.000). CONCLUSIONS: None of the tested tools were adapted for pregnancy, since a-priori scores were attributed for components already not consumed by pregnant females such as alcohol or recommended for daily or weekly consumptions such as whole dairy products and fish, respectively. In addition, the lack of inclusion of some traditional food ingredients of the MD implies the urge to create a new index adapted to pregnancy.
