Impact of Concomitant Cardiovascular Medication on Survival of Metastatic Renal Cell Carcinoma Patients Treated with Sunitinib or Pazopanib in the First Line

The effect of concomitant beta-blocker use on survival in patients with metastatic renal cell carcinoma treated with a vascular endothelial growth factor receptor inhibitors in the first line

PURPOSE

Vascular endothelial growth factor (VEGF) inhibition is one of the cornerstones of treatment in the treatment of metastatic renal cell carcinoma (mRCC). Since RCC is a disease of advanced age and hypertension as a side effect of VEGF receptor inhibitors, beta-blocker use is common in these patients. We aimed to compare the treatment efficacy and survival results in case of concomitant use of these two drugs due to the inhibition of VEGF in beta-blockers.

METHODS

A total of 121 patients with a diagnosis of mRCC who used sunitinib or pazopanib in first-line therapy were included in the study. These patients were divided into two groups as those using concomitant beta-blockers and those not using them.

RESULT

The median overall survival (mOS) of the patient using sunitinib or pazopanib and concomitant beta-blocker was 47 (95% CI 29.0-65.0) months, and the mOS of those not using concomitant beta-blocker was 18 (95% CI 8.9-27.1) months (p < 0.001). The median progression-free survival (mPFS) of the patients using sunitinib or pazopanib and concomitant beta-blocker was 20.4 (95% CI 4.5-40.1) months, and the mPFS of those not using it was 11.4 (95% CI 5.9-16.9) months (p = 0.042). Concomitant beta-blocker use was found to be a good prognostic factor for OS in the multivariate analysis (p = 0.029). In the multivariate analysis, concomitant beta-blocker use had a trend towards statistical significance for PFS (p = 0.062).

CONCLUSION

Concomitant use of betablockers with sunitinib or pazopanib is associated with longer overall survial and progression free survival.

Beta-blocker adjunct therapy as a prospective anti-metastatic with cardio-oncologic regulation

The prevailing treatment stratagem in cancer therapy still challenges the dilemma of a probable metastatic spread following an initial diagnosis. Including an anti-metastatic agent demands a significant focus to overrule the incidence of treatment failures. Adrenergic stimulation underlying the metastatic spread paved the way for beta blockers as a breakthrough in repurposing as an anti-metastatic agent. However, the current treatment approach fails to fully harness the versatile potential of the drug in inhibiting probable metastasis. The beta blockers were seen to show a myriad of grip over the pro-metastatic and prognostic parameters of the patient. Novel interventions in immune therapy, onco-hypertension, surgery-induced stress, induction of apoptosis and angiogenesis inhibition have been used as evidence to interpret our objective of discussing the potential adjuvant role of the drug in the existing anti-cancer regimens. Adding weight to the relative incidence of onco-hypertension as an unavoidable side effect from chemotherapy, the slot for an anti-hypertensive agent is necessitated, and we try to suggest beta-blockers to fill this position. However, pointing out the paucity in the clinical study, we aim to review the current status of beta blockers under this interest to state how the drug should be included as a drug of choice in every patient undergoing cancer treatment.

Influence of statin use on prognosis of patients with renal cell cancer: a meta-analysis

Background

Statin may confer anticancer efficacy, while the studies evaluating the influence of statin on survival of patients with renal cell cancer (RCC) yielded inconsistent results. A systematic review and meta-analysis was performed to investigate the association between statin use and survival of patients with RCC.

Materials and Methods

Cohort studies were identified by search of PubMed, Embase, and Web of Science databases according to the objective of the meta-analysis. A random-effect model incorporating the possible between-study heterogeneity was used for meta-analysis. Subgroup analyses according to study characteristics were also performed.

Results

Seventeen cohort studies involving 42528 patients with RCC were available for the meta-analysis. Results showed that statin use was associated with a better overall survival (OS, hazard ratio [HR]: 0.73, 95% confidence interval [CI]: 0.65 to 0.84, p < 0.001; I² = 40%), progression progression-free survival (PFS, HR: 0.82, 95% CI: 0.68 to 0.98, p = 0.03; I² = 52%), and cancer-specific survival (CSS, HR: 0.76, 95% CI: 0.59 to 0.99, p = 0.04; I² = 38%). Besides, for the outcome of OS and PFS, subgroup analyses showed similar results in patients with surgical and non-surgical anticancer treatments, and in patients with stage I-III and stage IV RCC (p values for subgroup difference all > 0.05).

Conclusions

Statin use may be associated with improved survival outcomes in patients with RCC. Although prospective clinical studies should be considered to validate these results, these findings suggest that statins may be potential adjuvant therapy for patients with RCC.

Statin use improves the efficacy of nivolumab in patients with advanced renal cell carcinoma

BACKGROUND

Statins are widely used in an ageing population, including subjects with solid malignancies. However, no conclusive evidence is currently available on their potential influence on patients' outcome. We aimed to assess whether statin exposure affects the survival of patients with metastatic renal cell carcinoma (mRCC) treated with nivolumab.

PATIENTS AND METHODS

Medical records of patients with documented mRCC treated with second- or third-line nivolumab were reviewed at ten institutions from Italy, Spain and the USA. Patients were assessed for overall survival (OS), progression-free survival (PFS), and overall clinical benefit. Univariate and multivariate analyses were used to explore the association of variables of interest with survival.

RESULTS

A total of 219 patients with mRCC receiving nivolumab between January 2016 and September 2021 were eligible for inclusion in this study; 59 (27%) were statin users. The median OS (34.4 versus 18.6 months, p = 0.017) and PFS (11.7 versus 4.6 months, p = 0.013) resulted apparently longer in statin users. Stratified by age, longer median OS and PFS were associated with statin exposure in both patients aged ≥70 y (median OS: 21.4 versus 10.1 months, p = 0.047; median PFS: 16.4 versus 4.6 months, p = 0.022) and <70 y (median OS: 34.4 versus 21.4 months, p = 0.043; median PFS: 10.3 versus 4.6 months, p = 0.042). Overall clinical benefit resulted higher in statin users than non-users (71% versus 54%, p = 0.030).

CONCLUSIONS

Our study suggests a prognostic impact of statin use in patients receiving nivolumab for mRCC.

Statins and renal cell carcinoma: Antitumor activity and influence on cancer risk and survival

Statins are commonly prescribed to reduce plasma cholesterol levels and risk of cardiovascular events and mortality. Statin exposure may have cancer-preventive properties in some solid tumors, including Renal Cell Carcinoma (RCC). Emerging evidences show that statins can inhibit RCC cell growth by inducing cell cycle arrest and apoptosis in a dose- and time-dependent manner. In addition, statins inhibit the phosphorylation of AKT, mammalian target of rapamycin (mTOR), and ERK leading to reduced motility of RCC cells. Interestingly, the potential impact of concomitant statin intake has been recently evaluated in RCC patients treated by targeted therapy or immunotherapy. In this review, we illustrate the most recent data on the preclinical activity of statins in Renal Cell Carcinoma models and discuss the impact of their use on the prevention and survival of patients affected by this tumor.

Risk Factors for the Comorbidity of Hypertension and Renal Cell Carcinoma in the Cardio-Oncologic Era and Treatment for Tumor-Induced Hypertension

Advances in tumor diagnosis and treatment, especially the use of targeted therapies, have remarkably improved the survival rate of patients with renal cell carcinoma (RCC), accompanied by higher hypertension (HTN) incidence among patients with RCC, reflecting the coming of a cardio-oncologic era. Therefore, for patients with RCC and HTN simultaneously, finding risk factors for the comorbidity and giving better clinical treatment have been urgent problems. In this review, we thoroughly investigated risk factors for the comorbidity of HTN and RCC based on preclinical and clinical studies. Firstly, RCC and HTN may have common risk factors, such as obesity, smoking, and other modifiable lifestyles. Secondly, RCC and HTN may lead to each other directly or indirectly by their therapies. We then discussed measures of reducing the comorbidity and treatment of HTN in patients with RCC. We also discussed the deficiency of current studies and pointed out future directions. In conclusion, this review aims to deepen the understanding of cardio-oncology and bring benefit to the population who are at high risk of getting or have already got RCC and HTN simultaneously.
