Simple Summary: Renal cancer is the eighth most frequent cancer in Europe, and its prevalence is increasing. Surgery is the treatment of choice for localised renal cell carcinoma requiring interventional management, but less invasive treatment methods are emerging. Stereotactic body radiotherapy (SBRT) utilises precise delivery of high doses of radiation to ablate the primary cancer. In our systematic review and meta-analysis, we pooled data from available prospective trials, including 13 studies involving 308 patients. The results of the meta-analysis show that SBRT for localised renal cell carcinoma is highly effective in controlling local diseases and has low complication rates. In the second year, 97% of patients were free from local recurrence. Only 3% experienced severe adverse events, which included abdominal pain and fatigue. SBRT presents a valuable treatment for patients who require treatment but cannot undergo surgery; however, it has not been yet confirmed to be equieffective to surgery as trials directly comparing these methods are missing. Context: Surgery is the gold standard for the local treatment of primary renal cell carcinoma (RCC), but alternatives are emerging. We conducted a systematic review and meta-analysis to assess the results of prospective studies using definitive stereotactic body radiotherapy (SBRT) to treat primary localised RCC. Evidence acquisition: This review was prospectively registered in PROSPERO (CRD42023447274). We searched PubMed, Embase, Scopus, and Google Scholar for reports of prospective studies published since 2003, describing the outcomes of SBRT for localised RCC. Meta-analyses were performed for local control (LC), overall survival (OS), and rates of adverse events (AEs) using generalised linear mixed models (GLMMs). Outcomes were presented as rates with corresponding 95% confidence intervals (95% CIs). Risk-of-bias was assessed using the ROBINS-I tool. Evidence synthesis: Of the 2983 records, 13 prospective studies (n = 308) were included in the meta-analysis. The median diameter of the irradiated tumours ranged between 1.9 and 5.5 cm in individual studies. Grade ≥ 3 AEs were reported in 15 patients, and their estimated rate was 0.03 (95%CI: 0.01–0.11; n = 291). One- and two-year LC rates were 0.98 (95%CI: 0.95–0.99; n = 293) and 0.97 (95%CI: 0.93–0.99; n = 253), while one- and two-year OS rates were 0.95 (95%CI: 0.88–0.98; n = 294) and 0.86 (95%CI: 0.77–0.91; n = 224). There was no statistically significant heterogeneity, and the estimations were consistent after excluding studies at a high risk of bias in a sensitivity analysis. Major limitations include a relatively short follow-up, inhomogeneous reporting of renal function deterioration, and a lack of prospective comparative evidence. Conclusions: The short-term results suggest that SBRT is a valuable treatment method for selected inoperable patients (or those who refuse surgery) with localised RCC associated with low rates of high-grade AEs and excellent LC. However, until the long-term data from randomised controlled trials are available, surgical management remains a standard of care in operable patients. [ABSTRACT FROM AUTHOR]

Hereditary leiomyomatosis and renal cell cancer (HLRCC) is a rare autosomal-dominant disorder caused by a heterozygous germline mutation in the fumarate hydratase (FH) gene. HLRCC is clinically characterized by the development of three tumors: uterine leiomyomata, cutaneous leiomyomata, and renal cell carcinoma (RCC). HLRCC-associated RCC is aggressive and diagnosed at a much earlier age than sporadic RCC. It is essential for carriers of HLRCC to undergo annual renal screening by magnetic resonance imaging to detect early stage RCCs. Metastatic HLRCC-associated RCC must be treated by systemic therapy; however, it is unclear which medicines are most effective in treating this cancer owing to its low incidence rate. Immune checkpoint inhibitor (ICI) combinations or ICIs plus tyrosine kinase inhibitors are administered as systemic therapy for clear cell RCC. Here, we report a patient with HLRCC-associated RCC treated with sequential therapy, including ipilimumab plus nivolumab combination and cabozantinib, after diagnosis of HLRCC-associated RCC using FoundationOne Liquid CDx and single-site analysis. We also investigated familial FH mutations and describe a new family pedigree for HLRCC. [ABSTRACT FROM AUTHOR]

On the contrary, one in three patients (33%) with grade 5 CKD required treatment discontinuation and HD initiation due to immune-related pneumonitis and colitis. Among all patients, three patients (43%) experienced grade 3 or more immune-related adverse events (irAEs) and required corticosteroid administration.

Adrenocortical carcinoma (ACC) is a rare and aggressive malignancy with a high recurrence rate after surgical therapy with curative intent. Adjuvant radiotherapy (RT) and mitotane therapy have been proposed as options following the adrenalectomy. However, the efficacy of adjuvant RT or mitotane therapy remains controversial. We aimed to evaluate the efficacy of adjuvant therapy in patients who underwent adrenalectomy for localised ACC. The PubMed, Scopus, and Web of Science databases were queried on March 2024 for studies evaluating adjuvant therapies in patients treated with surgery for localized ACC (PROSPERO: CRD42024512849). The endpoints of interest were overall survival (OS) and recurrence-free survival (RFS). Hazard ratios (HR) with 95% confidence intervals (95%CI) were pooled in a random-effects model meta-analysis. One randomized controlled trial (n = 91) and eleven retrospective studies (n = 4,515) were included. Adjuvant mitotane therapy was associated with improved RFS (HR: 0.63, 95%CI: 0.44-0.92, p = 0.016), while adjuvant RT did not reach conventional levels of statistical significance (HR:0.79, 95%CI:0.58-1.06, p = 0.11). Conversely, Adjuvant RT was associated with improved OS (HR:0.69, 95%CI:0.58-0.83, p<0.001), whereas adjuvant mitotane did not (HR: 0.76, 95%CI: 0.57-1.02, p = 0.07). In the subgroup analyses, adjuvant mitotane was associated with better OS (HR:0.46, 95%CI: 0.30-0.69, p < 0.001) and RFS (HR:0.56, 95%CI: 0.32-0.98, p = 0.04) in patients with negative surgical margin. Both adjuvant RT and mitotane were found to be associated with improved oncologic outcomes in patients treated with adrenalectomy for localised ACC. While adjuvant RT significantly improved OS in general population, mitotane appears as an especially promising treatment option in patients with negative surgical margin. These data can support the shared decision-making process, better understanding of the risks, benefits, and effectiveness of these therapies is still needed to guide tailored management of each individual patient., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Author(s).

(1) Background: Intravesical chemotherapy is the standard of care in intermediate-risk non-muscleinvasive bladder cancer (NMIBC). Different agents are used across the world based on availability, cost, and practice patterns. Epirubicin (EPI), one of these agents, has been used by many centers over many decades. However, its true differential efficacy compared to other agents and its tolerability are still poorly reported. We aimed to assess the differential efficacy and safety of intravesical EPI in NMIBC patients. (2) Methods : This study aimed to systematically review the efficacy and safety profile of Epirubicin (EPI) in the management of non-muscle invasive bladder cancer (NMIBC) compared to other adjuvant therapies. A systematic search of the PUBMED, Web of Science, clinicaltrials.gov, and Google Scholar databases was conducted on 31 December 2023, using relevant terms related to EPI, bladder cancer, and NMIBC. The inclusion criteria targeted studies that evaluated patients treated with EPI following the transurethral resection of bladder tumors (TURBT) for NMIBC and compared oncological outcomes such as recurrence and progression with other adjuvant therapies, including Mitomycin C (MMC), Gemcitabine (GEM), and Bacillus Calmette-Guérin (BCG). Additionally, studies investigating the safety profile of EPI administered intravesically at room temperature and under hyperthermia, as well as oncological outcomes associated with hyperthermic intravesical EPI administration, were included. (3) Results: Eleven studies reported adverse events after adjuvant intravesical instillations with EPI; the most frequently reported adverse events included cystitis (34%), dysuria, pollakiuria, hematuria, bladder irritation/spasms, fever, nausea and vomiting, and generalized skin rash (2.3%). Nine studies compared EPI to BCG in terms of recurrence and progression rates; BCG instillations showed a lower recurrence rate compared to EPI, with limited or non-significant differences in progression rates. Two studies found no significant differences between EPI and MMC regarding progression and recurrence rates. One study showed statistically significant lower recurrence and progression rates with GEM in high-risk NMIBC patients. Another study found no significant differences between EPI and GEM regarding recurrence and progression. (4) Conclusions : EPI exhibits similar oncological performances to Gemcitabine and Mitomycin C currently used for adjuvant therapy in NMIBC. Novel delivery mechanisms such as hyperthermia are interesting newcomers.
