Introduction: There is a significant gap in the literature concerning the effective management of second-line therapy for patients with metastatic renal cell carcinoma (RCC) who have received immune checkpoint inhibitors (ICIs). Most of the published articles were small multicenter series or phase 2 studies. To our knowledge, a systematic review that comprehensively outlines the range of treatment options available for patients with metastatic RCC who do not respond to first-line ICIs has not yet been conducted.

Introduction: This study evaluates the effects of radical prostatectomy (RP) or irradiation on overall survival (OS) and prostate cancer-specific mortality (PCSM) in older patients with localized prostate cancer (PC).

Materials And Methods: We conducted a comprehensive literature review across PubMed, EMBASE, and the Cochrane Library from inception up to December 2023 to identify studies comparing the outcomes of surgery or radiotherapy (RT) versus observation in patients aged 65 and older with localized PC. We pooled hazard ratios (HRs) for OS and PCSM using random-effects models.

In urothelial cancer of the bladder, the introduction of immunotherapy with immune checkpoint inhibitors represents progress in the management of the disease's early and advanced stages. In particular, recent studies have implemented these drugs in the neoadjuvant and adjuvant phases to treat muscle-invasive bladder cancer. In some studies, patients received neoadjuvant immune checkpoint inhibitors alone (PURE and ABACUS) to treat muscle invasive bladder cancer, whereas other studies provided this therapy to cisplatin-ineligible patients.

Allogenic red blood cell transfusions exert a potential detrimental effect on the survival when delivered to cancer patients undergoing surgery with curative intent. We performed a systematic review and meta-analysis to assess the association between perioperative allogenic red blood cell transfusions and risk of death as well as relapse after surgery for localized solid tumors. PubMed, the Cochrane Library, and EMBASE were searched from inception to March 2019 for studies reporting the outcome of patients receiving transfusions during radical surgery for non-metastatic cancer.

The COVID-19 pandemic has inevitably caused those involved in cancer care to change clinical practice in order to minimize the risk of infection while maintaining cancer treatment as a priority. General advice during the pandemic suggests that most patients continue with ongoing therapies or planned surgeries, while follow-up visits may instead be delayed until the resolution of the outbreak. We conducted a literature search using PubMed to identify articles published in English language that reported on care recommendations for cancer patients during the COVID-19 pandemic from its inception up to 1st June 2020, using the terms "(cancer or tumor) AND (COVID 19)".

Purpose: We investigated predictive factors of failure and performed a resource consumption analysis in patients who underwent active surveillance for nonmuscle invasive bladder cancer.

Materials And Methods: This prospective observational study monitored patients with a history of pathologically confirmed stage pTa (grade 1-2) or pT1a (grade 2) nonmuscle invasive bladder cancer, and recurrent small size and number of tumors without hematuria and positive urine cytology. The primary end point was the failure rate of active surveillance.

Background: Open prostatectomy (OP) and transurethral resection of the prostate (TURP) have traditionally been the most common surgical approaches for the treatment of benign prostatic hyperplasia causing bladder outlet obstruction and have certainly passed the test of time. In time, many endoscopic surgical procedures have been described as an alternative mini-invasive treatment. Holmium laser enucleation (HoLEP) guaranteed functional outcomes similar to OP and TURP with lower perioperative complication rates for any prostate size.

Several prognostic factors that influence overall survival after radical nephroureterectomy for upper urinary tract urothelial carcinoma have been described. We have performed a systematic review of the literature and meta-analysis. The clinicopathological factors associated with an increased risk of death were age, multifocality, lymphovascular invasion, pT3-4 stage, pT2 vs View Article and Find Full Text PDF

Cytoreductive nephrectomy (CN) in metastatic renal cell carcinoma (mRCC) (resection of the primary tumor for debulking purposes) was considered to be an important part of oncological treatment when used with cytokines, and was associated with an overall survival (OS) benefit. However, the role of CN in the targeted therapy era is not well-defined. We conducted a systematic review and meta-analysis to determine the prognostic role of CN performed during the course of advanced disease in patients with mRCC treated with molecular agents.

Objective: To systematically evaluate the evidence on the predictors of the upgrading and biochemical recurrence of prostate cancer (PC) in those patients with low-risk disease assigned to active surveillance (AS).

Materials And Methods: An electronic search of the PubMed, SCOPUS, Web of Science, CINAHL, Cochrane Library, Google Scholar, and Embase databases was performed for all reports that included detailed results of multivariate analyses of the predictors of PC reclassification and biochemical relapse during AS. Cumulative analyses of available hazard ratios (HRs) and their corresponding 95% confidence intervals were conducted using the RevMan 5.

Background: Radical prostatectomy (RP) is one of the treatment options for localized, high-risk prostate cancer (PC), but it has never been compared with external beam radiotherapy (RT), which is an alternative approach, in a large randomized trial. To compare the outcomes of patients treated with surgery versus RT, we performed a metaanalysis of available studies on this topic.

Materials And Methods: We performed a search of MEDLINE, EMBASE, Web of Science, SCOPUS, and The Cochrane Central Register of Controlled Trials (CENTRAL) for randomized or observational studies that investigated overall survival (OS) and PC-specific mortality (PCSM) risks in relation to use of surgery or RT in patients with high-risk PC.

Context: Neoadjuvant chemotherapy before radical cystectomy (RC) is the preferred initial option for muscle-invasive bladder cancer (BCa). As in rectal and breast cancer, pathologic downstaging is associated with increased overall survival (OS).

Objective: We conducted a meta-analysis to determine whether pathologic complete response (pCR) (pT0N0M0) after neoadjuvant chemotherapy is associated with a better outcome in muscle-invasive BCa.

Context: Holmium laser enucleation of the prostate (HoLEP) and 532-nm laser vaporisation of the prostate (with potassium titanyl phosphate [KTP] or lithium borate [LBO]) are promising alternatives to transurethral resection of the prostate (TURP) and open prostatectomy (OP).

Objective: To assess safety, efficacy, and durability by analysing the most recent evidence of both techniques, aiming to identify advantages, pitfalls, and unresolved issues.

Evidence Acquisition: A Medline search of recently published data (2006-2008) regarding both techniques over the last 2 yr (January 2006 to September 2008) was performed using evidence obtained from randomised trials (level of evidence: 1b), well-designed controlled studies without randomisation (level of evidence: 2a), individual cohort studies (level of evidence: 2b), individual case control studies (level of evidence: 3), and case series (level of evidence: 4).

Mixed epithelial and stromal tumor of the kidney is a recently recognized category of lesions occurring mostly in adult, middle-age women with a history of hormonal treatment. We present a rare case of a 58-year-old asymptomatic man without a history of hormonal treatment with a tumor characterized by proliferation of multiple cysts lined by single layers of epithelial cells and hypercellular stroma of spindle "ovarian-like" cells. Immunohistochemically, the stromal cells reacted against estrogen and progesterone receptors, vimentin, desmin, and CD34.
