ABSTRACT

BACKGROUND: Immunotherapy-based combinations including pembrolizumab plus lenvatinib are the standard of care for patients with first-line clear-cell renal cell carcinoma, but these combinations are not well characterised in non-clear-cell renal cell carcinoma. We aimed to assess the activity and safety of pembrolizumab plus lenvatinib as a first-line treatment for patients with advanced non-clear-cell renal cell carcinoma.

METHODS: KEYNOTE-B61 is a single-arm, phase 2 trial being conducted at 48 sites (hospitals and cancer centres) in 14 countries (Australia, Canada, France, Hungary, Ireland, Italy, Poland, South Korea, Russia, Spain, Türkiye, Ukraine, the UK, and the USA). Adult patients (aged ≥18 years) with previously untreated stage IV non-clear-cell renal cell carcinoma and a Karnofsky performance status of 70% or higher were eligible for enrolment. All enrolled patients received pembrolizumab 400 mg intravenously every 6 weeks for up to 18 cycles (2 years) plus lenvatinib 20 mg orally once daily or until disease progression, unacceptable toxicity, or withdrawal; lenvatinib could be continued beyond 2 years. The primary endpoint was the proportion of patients with a confirmed objective response as per adjusted Response Evaluation Criteria in Solid Tumours (version 1.1) assessed by independent central review. Activity and safety were analysed in all patients who received at least one dose of study treatment (the as-treated population). This trial is registered with ClinicalTrials.gov (NCT04704219) and is no longer recruiting participants but is ongoing.

FINDINGS: Between Feb 23, 2021, and Jan 21, 2022, 215 patients were screened; 158 were enrolled and received treatment. Median age at baseline was 60 years (IQR 52-69), 112 (71%) of 158 patients were male, 46 (29%) were female, 128 (81%) were White, 12 (8%) were Asian, three (2%) were Black or African American, and 15 (9%) were missing data on race. As of data cutoff (Nov 7, 2022), median study follow-up was 14·9 months (IQR 11·1-17·4). 78 of 158 patients had a confirmed objective response (49%; 95% CI 41-57), including nine (6%) patients with a confirmed complete response and 69 (44%) with a confirmed partial response. Grade 3-4 treatment-related adverse events occurred in 81 (51%) of 158 patients, the most common of which were hypertension (37 [23%] of 158), proteinuria (seven [4%]), and stomatitis (six [4%]). Serious treatment-related adverse events occurred in 31 (20%) of 158 patients. Eight (5%) patients died due to adverse events, none of which was considered related to the treatment by the investigators (one each of cardiac failure, peritonitis, pneumonia, sepsis, cerebrovascular accident, suicide, pneumothorax, and pulmonary embolism).

INTERPRETATION: Pembrolizumab plus lenvatinib has durable antitumour activity in patients with previously untreated advanced non-clear-cell renal cell carcinoma, with a safety profile consistent with that of previous studies. Results from KEYNOTE-B61 support the use of pembrolizumab plus lenvatinib as a first-line treatment option for these patients.

High-intensity interval training and thromboembolic events during chemotherapy for testicular cancer: a retrospective analysis from the Body & Cancer cohort

Acta Oncol. 2023 Jun;62(6):666-672. doi: 10.1080/0284186X.2023.2225145. Epub 2023 Jul 14.

ABSTRACT

Background:Men with testicular cancer receiving platinum-based chemotherapy have an increased risk of thromboembolic events, with incidence rates between 8-24%. A recent trial evaluating the effect of high-intensity interval training (HIIT) prematurely closed as three out of nine participants (33%) in the intervention group developed a thromboembolic event. The purpose of this retrospective cohort study was: 1) (primary) to evaluate the incidence of thromboembolic events in men receiving chemotherapy for testicular cancer who had participated in HIIT during a 6-week exercise program (Body & Cancer) 2) to describe the feasibility of this program.Material and methods: Forty men who had participated in at least one HIIT session from February 2007 to February 2020 were included. Electronic medical records were searched for incident thromboembolic events (arterial and venous) during Body & Cancerand up to one-year post-chemotherapy. Attendance, cardiorespiratory fitness (VO2-peak), and upper and lower extremity muscular strength (1 repetition maximum (RM)) were obtained from the Body & Cancerdatabase.Results: One participant developed a thromboembolic event during Body & Cancer. No participants developed a thromboembolic event in the follow-up period. In all, data represent 160 HIIT sessions with a median attendance of eight sessions [range 1-19]. Statistically significant increases in upper and lower extremity strength were observed (8.6 (4.2 to 13.0) and 26.0 (14.9 to 37.0) kg, respectively). No significant increase in cardiorespiratory fitness was found (0.14 (-0.03 to 0.31) l/min).Conclusion: While conclusions on the safety of HIIT cannot be drawn, data from the present study do not support previous findings cautioning avoidance of HIIT due to a possible added risk of thromboembolic events in men receiving platinum-based chemotherapy for testicular cancer. Considering the potential for positive effects on cardiovascular outcomes associated with HIIT, future studies with robust design should be performed in this population to confirm these observations.

Diagnostic Value of Three-Dimensional Speckle Tracking Imaging Strain Parameters for Detection of Cancer Chemotherapy-Related Cardiac Dysfunction: A Meta-Analysis

Arq Bras Cardiol. 2023 Jul;120(8):e20220370. doi: 10.36660/abc.20220370.

ABSTRACT

BACKGROUND: Chemotherapeutic agents (e.g., anthracyclines, trastuzumab) commonly used for treating malignant tumors have been demonstrated to have cardiotoxic effects, which is associated with poor prognosis. Three-dimensional echocardiography has been used to predict cancer chemotherapy-induced cardiac dysfunction.

OBJECTIVES: Evaluation of the diagnostic performance of strain parameters, global area strain (GAS), longitudinal strain (GLS), circumferential strain (GCS), and radial strain (GRS) by meta-analysis.

METHODS: Relevant studies were searched from the Embase, PubMed, and Web of Science databases. Statistical analysis was performed using Stata 12. The summary receiver operating characteristic curve, sensitivity, specificity, positive likelihood ratio (PLR), negative likelihood ratio (NLR), and corresponding 95% confidence interval for the four strain parameters were pooled. P<0.05

RESULTS: Nine studies involving 650 participants were included. GAS and GLS showed significant diagnostic advantages over GCS and GRS. For GAS, the sensitivity was 0.85 (0.70, 0.93) and specificity was 0.82(0.78, 0.86) with PLR of 4.76 (3.55, 6.39) and NLR of 0.18 (0.09, 0.39) and an area under the curve (AUC) of 0.85 (0.82, 0.88). For GLS, the sensitivity was 0.81 (0.74, 0.86) and specificity was 0.81(0.68, 0.90) with PLR of 4.35(2.42, 7.80) and NLR of 0.23 (0.17, 0.33) and an AUC of 0.85 (0.82, 0.88). The GCS showed a sensitivity of 0.63 and a specificity of 0.79 with an AUC of 0.77. The GRS showed a sensitivity of 0.74 and a specificity of 0.66 with an AUC of 0.73.

CONCLUSION: 3D-STI strain parameters GAS and GLS showed good performance in detecting early cardiac dysfunction in patients with tumors receiving chemotherapy.

Cardiorenal Syndrome: A Literature Review

Cureus. 2023 Jul 1;15(7):e41252. doi: 10.7759/cureus.41252. eCollection 2023 Jul.

ABSTRACT

Cardiorenal syndrome (CRS) is a condition characterized by the intricate two-way relationship between the heart and kidneys, which can lead to acute or chronic dysfunction in these organs. The interplay between cardiorenal connectors and both hemodynamic and non-hemodynamic factors is crucial to understanding this syndrome. The clinical importance of these interactions is evident in the changes observed in hemodynamic factors, neurohormonal markers, and inflammatory processes. Identifying and understanding biomarkers associated with CRS is valuable for early detection and enabling intervention before significant organ dysfunction occurs. This comprehensive review focuses on the clinical significance of biomarkers in the diagnosis, prognosis, and management of CRS. Finally, it highlights the necessity for further advancements in managing this condition.

Late-onset cardiotoxicity in patients with HER2-positive metastatic breast cancer receiving trastuzumab-based therapy

J Oncol Pharm Pract. 2023 Aug 1:10781552231193149. doi: 10.1177/10781552231193149. Online ahead of print.

ABSTRACT

INTRODUCTION: Patients with human epidermal growth factor receptor 2 (HER2)-positive metastatic breast cancer (MBC) typically receive long-term trastuzumab treatment for several years. The aim of our study is to identify the incidence and characterize late-onset cardiotoxicity in patients with HER2-positive MBC receiving trastuzumab-based therapy.

METHODS: We retrospectively reviewed charts of HER2-positive MBC patients who received >1 year of trastuzumab-based therapy at the Massachusetts General Hospital Cancer Center over three-year period. The primary endpoint was development of trastuzumab-induced cardiotoxicity (TIC). Secondary endpoints included time to TIC development, incidence/duration of trastuzumab interruption due to TIC, incidence of permanent discontinuation of trastuzumab due to TIC, clinic visit, or hospitalization due to TIC.

RESULTS: Thirty-seven patients were included. Mean age was 56 years (range: 33-78 years, SD 9.5). Seven patients received prior doxorubicin and 14 patients received previous or concurrent breast irradiation. Mean duration of trastuzumab-based therapy was 57 months (range: 14-140 months, SD 39.3). Seven patients (18.9%) experienced TIC resulting in treatment interruption for two patients (28 and 78 days). The median time from starting trastuzumab therapy to TIC was 14 months (interquartile range: 11-29.5 months). The mean number of left ventricular ejection fraction (LVEF) assessment completed per year was 2.7 (range: 1.2-6.6, SD 1.1).

CONCLUSION: Cardiotoxicity occurred in a minority of patients with HER2-positive MBC receiving trastuzumab-based therapy for more than one year. LVEF reductions to below the institutional lower limit of normal and therapy modifications were uncommon.

Statins as preventive therapy for anthracycline cardiotoxicity: A meta-analysis of randomized controlled trials

Int J Cardiol. 2023 Jul 30:131219. doi: 10.1016/j.ijcard.2023.131219. Online ahead of print.

ABSTRACT

BACKGROUND: Cardiotoxicity occurs in 5-20% of cancer patients who receive anthracyclines. The aim of this study was to pool all the randomized controlled trials (RCTs) investigating the cardio-protective role of statins in patients treated with anthracyclines.

METHODS: PubMed and Scopus electronic databases were scanned for eligible studies up to May 3rd, 2023. A total of 5 RCTs with 808 patients were included. Efficacy endpoints were the rate of anthracycline-mediated cardiotoxicity, the incidence of hospitalization for heart failure (HF), left ventricular ejection fraction (LVEF) value after anthracycline treatment, and ∆LVEF calculated as the difference in LVEF before and after anthracycline therapy. Safety endpoints [i.e., the incidence of muscle pain and serious adverse events (SAE)] were also assessed.

RESULTS: On pooled analysis, the statin-treated group had a lower incidence of cardiotoxicity compared to the placebo group [risk ratio (RR) 0.52, 95% confidence Interval (CI) 0.33-0.83, P = 0.01; I2 = 0%], as well as higher mean LVEF [Mean difference (MD) 1.88, 95% CI 0.66-3.1, P < 0.01; I2 = 57.3%)] and a more favorable ∆LVEF during follow-up (MD 2.38, 95% CI -0.03 - +4.79, P = 0.05; I2 = 99%), despite no significant difference in terms of hospitalization for HF and rate of adverse events. Of note, severe heterogeneity affected the analyses for both LVEF and ΔLVEF.

CONCLUSIONS: The current meta-analysis of all RCTs conducted so far shows an overall beneficial effect of statins on the risk of anthracyclines induced cardiotoxicity and LVEF preservation. No difference was observed in the rate of HF hospitalization. . More powered RCTs are needed to fully investigate the impact of statins on prognosis in patients receiving anthracyclines therapy.
