Purpose Of Review: In this review, we discuss which patients with metastatic clear cell renal cell carcinoma (mRCC) may be most suitable for frontline tyrosine kinase inhibitor (TKI) monotherapy, a treatment option supported by emerging long-term efficacy data including overall survival and quality of life. We specifically focus on tivozanib, a potent and selective inhibitor of vascular endothelial growth factor receptor, which has comparable efficacy to other single-agent TKIs in frontline treatment for mRCC while exhibiting fewer off-target side effects.

Recent Findings: Combination therapy with TKIs and checkpoint inhibitors (CPIs) and CPI/CPI combination therapies, as well as TKI monotherapy are recommended frontline treatment options for mRCC.

Background: Renal cell carcinoma (RCC) accounts for about 13.5% of all urological tumors. Healthcare research analyzes whether treatment recommendations from controlled studies or guidelines are being implemented in routine care.

The risk of recurrence in patients with muscle invasive bladder cancer (MIBC) after radical cystectomy depends on the pathological tumor stage. In particular, patients with lymph node metastasis (pN+), locally advanced (≥pT3), or residual muscle invasive tumor despite neoadjuvant chemotherapy are at high risk. Currently, the importance of adjuvant therapy with immune checkpoint inhibitors is increasing in the context of perioperative systemic therapeutic concepts.

Background: Approximately 15 000 people receive a diagnosis of renal cell carcinoma (RCC) in Germany each year; in 20-30% of cases, metastatic RCC (mRCC) is already present at the time of diagnosis. This disease in the metastatic stage is still mainly treated palliatively, yet the multimodal therapeutic landscape has changed markedly over the past 15 years, with the approval of many new treatments for patients with mRCC.

Methods: This review is based on prospective studies retrieved by a selective search in PubMed and the ASCO and ESMO databases and on the German and European oncological and urological guidelines for RCC.

Background: The prognosis for patients improves significantly with effective cardiopulmonary resuscitation (CPR) performed by bystanders. Current research indicates that individuals who receive CPR from trained bystanders have a greater likelihood of survival compared to those who receive dispatcher-assisted CPR from untrained laypersons. This cluster-randomised controlled trial assessed the impact of a 30-min online training session prior to a simulated cardiac arrest situation with dispatcher-assisted CPR (DA-CPR) on enhancing Basic Life Support (BLS) performance.

Background: Renal cell carcinoma is the third most common tumor among urological tumors. In Germany more than 14,000 people are affected every year. The sex ratio is 2/3 men and 1/3 women.

The German Society of Uro-Oncologists ("Deutsche Uro-Onkologen e.V.", d-uo) provides a national registry for urothelial cancer (UroNat) and a national registry for prostate cancer (ProNAT).

At the beginning of 2017, the German Society of Uro-Oncologists (d-uo) had the idea of designing a documentation platform that would enable d-uo members to report cancer cases to the cancer registry and transfer data to d-uo's own database - without a double effort. The cancer registry reimburses the first notification of a tumour with €18. As the only provider, d-uo reimburses its members for the documentation effort associated with the additional notification to d-uo with a further €18.

The current cancer registry notification, which was introduced in Germany as a mandatory institution in 2015, has its starting point in the National Cancer Plan of 2008. Other milestones include the Federal Cancer Registry Data Act (2009), the Cancer Early Detection and Registry Act (2013), the Uniform Oncological Basic Data Set (2014/2021) with its modules (e.g.

Article Synopsis
  • The approval of tyrosine kinase inhibitors and checkpoint inhibitors marked a significant advancement in treating metastatic renal cell carcinoma (mRCC), but real-world data on their effectiveness is limited.
  • The PAZOREAL study examined the real-world effectiveness and safety of pazopanib, nivolumab, and everolimus in 376 mRCC patients, focusing on various outcomes like overall survival and disease control rates.
  • Results showed that first-line pazopanib had a median time on the drug of 6.3 months, an overall survival of 35.9 months, a disease control rate of 56.9%, and no new safety concerns arose, contributing valuable data for future treatments.

Introduction: Patients with bone metastasis due to prostate cancer often present allover reduced bone mineral density. Additionally, patients with bone metastatic castration-resistant prostate cancer (mCRPC) have a relevant risk for skeletal-related events (SRE). We herein present real-world data (RWD) regarding osteoprotection in mCRPC patients with bone metastasis treated by German urologists in private practice.

Introduction: Patients with prostate cancer often present with reduced bone mineral density. We herein present real-world data (RWD) regarding osteoprotection in patients with non-metastatic hormone-sensitive prostate cancer (nmHSPC) receiving androgen deprivation therapy (ADT) treated by German urologists in private practice.

Material And Methods: This is a questionnaire-based study including members of d-uo ("Deutsche Uro-Onkologen", German uro-oncologists).

During phase III study ERA-223, patients under combination therapy with radium-223 and abiraterone showed an increased risk of bone fractures and a possible higher risk of death. This observation led to a change in the German therapeutic guidelines in 2018. Radium-223 is now only allowed as a third-line monotherapy (besides ADT) in patients with metastatic castration resistant prostate cancer (mCRPC) with symptomatic bone lesions without known visceral metastases or for patients with mCRPC, for whom no other available systematic therapy is suitable.

Background: This study aimed to determine whether prehospital qSOFA (quick sequential organ failure assessment) assessment was associated with a shortened 'time to antibiotics' and 'time to intravenous fluid resuscitation' compared with standard assessment.

Methods: This retrospective study included patients who were referred to our Emergency Department between 2014 and 2018 by emergency medical services, in whom sepsis was diagnosed during hospitalization. Two multivariable regression models were fitted, with and without qSOFA parameters, for 'time to antibiotics' (primary endpoint) and 'time to intravenous fluid resuscitation'.

Article Synopsis
  • Researchers looked at proteins in prostate cancer to better predict how dangerous the cancer is.
  • They found that certain proteins and the stability of DNA in tumors can help tell if patients will live longer or have worse outcomes.
  • A new scoring method using these findings is better at predicting survival than the old methods.

In the treatment of advanced renal cell carcinoma, anti-VEGFR tyrosine kinase inhibitors (TKI) have been replaced mostly by immunotherapy combinations with checkpoint inhibitors (CPI), especially in first line therapy. Due to these novel therapies, the prognosis of patients has been improved further. In pivotal studies a median overall survival of 3-4 years has been achieved.

Most studies indicate no benefit of adjuvant therapy with VEGFR tyrosine kinase inhibitors in advanced renal cell carcinoma (RCC). PROTECT (NCT01235962) was a randomized, double-blind, placebo-controlled phase 3 study to evaluate adjuvant pazopanib in patients with locally advanced RCC at high risk of relapse after nephrectomy (pazopanib, n = 769; placebo, n = 769). The results of the primary analysis showed no difference in disease-free survival between pazopanib 600 mg and placebo.

Due to novel therapies, the prognosis of patients with metastatic renal cell carcinoma (mRCC) has improved. A median overall survival of more than two years is a realistic goal. Immunotherapy combinations with checkpoint inhibitors or checkpoint inhibitors and the tyrosine kinase inhibitor axitinib are new first-line options.
