Cabozantinib is approved for the treatment of renal cell carcinoma (RCC). However, prognostic factors are still lacking in this context. The aim of this study was to evaluate prognostic factors in RCC patients treated with second- or third-line cabozantinib. A multicenter retrospective real-world study was conducted, involving 32 worldwide centers. A total of 237 patients with histologically confirmed clear-cell and non-clear-cell RCC who received cabozantinib as second- or third-line therapy for metastatic disease were included. We analyzed overall survival (OS), progression-free survival (PFS) and time-to-strategy failure (TTSF) using Kaplan–Meier curves. Cox proportional models were used at univariate and multivariate analyses.The median PFS and OS of cabozantinib were 7.76 months (95% CI 6.51–10.88) and 11.57 months (95% CI 10.90–not reached (NR)) as second-line and 11.38 months (95% CI 5.79–NR) and NR (95% CI 11.51–NR) as third-line therapy. The median TTSF and OS were 11.57 and 15.52 months with the sequence of cabozantinib–nivolumab and 25.64 months and NR with nivolumab–cabozantinib, respectively. The difference between these two sequences was statistically significant only in good-risk patients. In the second-line setting, hemoglobin (Hb) levels (HR= 2.39; 95% CI 1.24–4.60, p = 0.009) and IMDC (International Metastatic Renal Cell Carcinoma Database Consortium) group (HR = 1.72, 95% CI 1.04–2.87, p = 0.037) were associated with PFS while ECOG-PS (HR = 2.33; 95%CI, 1.16–4.69, p = 0.018) and Hb levels (HR = 3.12; 95%CI 1.18–8.26, p = 0.023) correlated with OS at multivariate analysis, while in the third-line setting, only Hb levels (HR = 2.72; 95%CI 1.04–7.09, p = 0.042) were associated with OS. Results are limited by the retrospective nature of the study.This real-world study provides evidence on the presence of prognostic factors in RCC patients receiving cabozantinib.

Cardiovascular (CV) diseases (CVD) are a major cause of long-term morbidity and mortality affecting life expectancy amongst cancer survivors. In recent years, because of the possibility of early diagnosis and the increased efficacy of neo-adjuvant and adjuvant systemic treatments (targeting specific molecular pathways), the high percentage of survival from breast cancer led CVD to become the first cause of death among survivors. Therefore, it is mandatory to adopt cardioprotective strategies to minimize CV side effects and CVD in general in breast cancer patients. Cancer therapeutics-related cardiac dysfunction (CTRCD) is a common group of side effects of chemotherapeutics widely employed in breast cancer (e.g., anthracycline and human epidermal growth factor receptor 2 inhibitors). The aim of the present manuscript is to propose a pragmatic multidisciplinary stepwise approach for prevention, early detection, and treatment of cardiotoxicity in patients with breast cancer.

Early detection and treatment of cancer have led to a noticeable reduction in both mortality and morbidity. However, chemotherapy and radiotherapy could exert cardiovascular (CV) side effects, impacting survival and quality of life, independent of the oncologic prognosis. In this regard, a high clinical index of suspicion is required by the multidisciplinary care team in order to trigger specific laboratory tests (namely natriuretic peptides and high-sensitivity cardiac troponin) and appropriate imaging techniques (transthoracic echocardiography along with cardiac magnetic resonance, cardiac computed tomography, and nuclear testing (if clinically indicated)), leading to timely diagnosis. In the near future, we do expect a more tailored approach to patient care within the respective community along with the widespread implementation of digital health tools.

PURPOSE: Sarcomatoid renal cell carcinoma (sRCC) represents a kidney malignancy with a sarcomatoid component associated with poor prognosis. Immunotherapy (IO)-based combinations demonstrated promising activity in sRCC, yet real-world evidence (RWE) remains limited. We aimed to characterize the clinicopathologic features and outcomes of patients with metastatic sRCC treated with first-line immune-based combinations. PATIENTS AND METHODS: This retrospective analysis from the ARON-1 study included 350 patients with histologically confirmed metastatic sRCC treated with first-line IO + IO, or IO + tyrosine kinase inhibitor across 66 centers in 21 countries (2016-2024). Overall survival (OS) was analyzed using Kaplan-Meier and Cox regression methods. Correlations between 2-year OS and clinical variables were assessed using Pearson's coefficient. RESULTS: After a median follow-up of 19.1 months, median OS was 26.9 months (95% CI, 21.6 to 43.3). OS was longer in males (43.3 v 15.3 months in females; P < .001), in whom underwent nephrectomy (32.3 v 20.7 months; P = .002), and in patients without hepatic (32.3 v 15.3 months; P < .001), without skeletal (41.0 v 20.0 months; P = .007), or without lymph node metastases (43.3 v 24.6 months; P = .037). Median OS varied by International Metastatic RCC Database Consortium (IMDC) risk group: 66.5, 29.4, and 11.7 months in favorable-, intermediate-, and poor-risk patients, respectively ( P < .001). Different IO regimens showed variable outcomes by risk subgroup. Limitations include retrospective design and lack of central pathology review. CONCLUSION: First-line IO-based combinations provide clinically meaningful survival in sRCC, with outcomes affected by sex, metastatic sites, and IMDC risk. This RWE may support a tailored therapeutic approach on the basis of baseline prognostic factors.

The Meet-URO score provided a more accurate prognostication than the international metastatic RCC database consortium (IMDC) risk group classification for patients with metastatic renal cell carcinoma (mRCC) by incorporating the pretreatment neutrophil-to-lymphocyte ratio (NLR) and the presence of bone metastases in different settings of the disease. To additionally validate the Meet-URO score on overall survival (OS) in a cohort of mRCC patients treated with first-line pembrolizumab plus axitinib, a post hoc analysis of the observational prospective ProPAXI study was conducted. Progression-free survival (PFS) was also considered. Harrell’s C-index was used to compare the discriminative ability on OS and PFS. Overall, the ProPAXI study included 170 patients. Both the five- and the three-risk group Meet-URO score were evaluated to account for the small sample size. The five Meet-URO risk group score showed a mOS of 27.1 months (p = 0.064) and 10.3 (p = 0.014) months for group 4 and group 5, respectively, while it was not reached for the other groups (p < 0.01). Although a worsening of PFS was observed with increasing the risk group, these differences were not statistically significant (p =0.19). Similar results were observed fot the three-risk group Meet-URO score. Both five and the three Meet-URO risk groups showed a better C-index for OS (0.69 and 0.66, respectively) compared to IMDC (0.62) and for PFS (0.60 and 0.59, respectively) compared to IMDC (0.56). These findings suggest that the Meet-URO score may provide more accurate prognostic stratification than IMDC alone in mRCC patients treated with first-line pembrolizumab and axitinib.
