ABSTRACT

INTRODUCTION: Sequential anti-PD-(L)1 followed by small targeted therapy use is associated with increased prevalence of adverse events (AEs) in non-small cell lung cancer (NSCLC). KRASG12C inhibitor sotorasib may trigger severe immune-mediated hepatotoxicity when used in sequence or in combination with anti-PD-(L)1. This study was designed to address whether sequential anti-PD-(L)1 and sotorasib therapy increases the risk of hepatotoxicity and other AEs.

METHODS: This is a multicenter, retrospective study of consecutive advanced KRASG12C-mutant NSCLC treated with sotorasib outside clinical trials in 16 French medical centers. Patient records were reviewed to identify sotorasib-related AEs (NCI-CTCAE v5.0). Grade 3 and higher AE was considered as severe. Sequence group was defined as patients who received an anti-PD-(L)1 as last line of treatment before sotorasib initiation and control group as patients who did not receive an anti-PD-(L)1 as last line of treatment before sotorasib initiation.

RESULTS: We identified 102 patients who received sotorasib, including 48 (47%) in sequence group and 54 (53%) in control group. Patients in control group received an anti-PD-(L)1 followed by at least one treatment regimen before sotorasib in 87% of the cases or did not receive an anti-PD-(L)1 at any time before sotorasib in 13% of the cases. Severe sotorasib-related AEs were significantly more frequent in sequence group compared to control group (50% vs 13%, p<0.001).<0.001).

CONCLUSIONS: Sequential anti-PD-(L)1 and sotorasib therapy is associated with a significantly increased risk of severe sotorasib-related hepatotoxicity and severe non-liver AEs. We suggest avoiding starting sotorasib within 30 days from the last anti-PD-(L)1 infusion.

Clinical Outcomes and Prognostic Factors of Patients With Early Malignant Melanoma in One Latin American Country: Results of the Epidemiological Registry of Malignant Melanoma in Colombia Study

JCO Glob Oncol. 2023 May;9:e2200377. doi: 10.1200/GO.22.00377.

ABSTRACT

To describe the population with early malignant melanoma, we performed a cohort study on the basis of the Epidemiological Registry of Malignant Melanoma in Colombia-Asociacion Colombiana de Hematologia y Oncologia. From January 2011 until December 2021, 759 patients were included; the average age was 66 years, 57% were women, acral lentiginous histology was found in 27.8% of patients, and the median follow-up was 36.5 months. The prognostic factors for overall survival in our population are Eastern Cooperative Oncology Group 3-4 (hazard ratio [HR], 13.8), stage III (HR, 5.07), received radiotherapy (HR, 3.38), ulceration on histology (HR, 2.68), chronic sun exposure (HR, 2.3), low income (HR, 2.04), previous local surgery (HR, 0.27), and have received adjuvant treatment (HR, 0.41).

Assessment of left heart dysfunction to predict doxorubicin cardiotoxicity in children with lymphoma

Front Pediatr. 2023 May 5;11:1163664. doi: 10.3389/fped.2023.1163664. eCollection 2023.

ABSTRACT

OBJECTIVES: The objectives of this study were to assess the changes in the left myocardial function after chemotherapy for childhood lymphoma and observe the predictive or monitor value for cancer treatment-related cardiac dysfunction (CTRCD) by speckle-tracking echocardiography.

METHODS: A total of 23 children with histopathological diagnoses of lymphoma were included, with age-matched normal controls. Comparative analysis of clinical serological tests and left heart strain parameters in children with lymphoma, including left ventricular global longitudinal strain (LVGLS); global myocardial work (GMW) indices, which include global work index (GWI), global constructive work (GCW), global wasted work, and global work efficiency; and the LS of subendocardial, middle, and subepicardial layer myocardium during left ventricular systole were measured: left atrial strain of reservoir phase (LASr), left atrial strain of conduit phase (LAScd), and left atrial strain of contraction phase (LASct).

RESULTS: One-way ANOVA showed that GLS, GWI, GCW, LASr, and LAScd were closely associated with CTRCD and multivariate logistic regression analysis showed that GLS was the most sensitive predictor for detecting patients at lofty risk of anthracycline-related cardiotoxicity. Both before and after chemotherapy, GLS in the left ventricle showed a pattern of basal segment < middle segment < apical segment and subepicardial < middle < subendocardial layer (p < 0.05), and the degree of decrease also showed a regular pattern of epicardial layer < middle layer < subendocardial layer while the difference was not significant (p > 0.05). After chemotherapy, maximum flow rate in early mitral relaxation/left atrial systolic maximum flow rate (E/A) and left atrial volume index of each group were in the normal range, and the values of LASr, LAScd, and LASct slightly increased in the second cycle and decreased significantly in the fourth cycle after chemotherapy, reaching the lowest level; LASr and LAScd were positively correlated with GLS.

CONCLUSION: LVGLS is a more sensitive and earlier indicator to predict CTRCD compared with conventional echocardiography-related parameters and serological markers, and GLS of each myocardial layer showed a certain regularity. Left atrial strain can be used for early monitoring of cardiotoxicity in children with lymphoma after chemotherapy.

Recurrent cardiotoxicity in a fluoropyrimidine treated cancer patient - case report and practical recommendations

Arch Clin Cases. 2023 May 18;10(2):55-60. doi: 10.22551/2023.39.1002.10241. eCollection 2023.

ABSTRACT

Fluoropyrimidines remain some of the most used chemotherapeutics, despite the appearance in the therapeutic arsenal of targeted therapy and immunotherapy. Fluropyrimidines related cardiotoxicity is an undesirable adverse event and affects almost 20% of patients. The mechanisms of fluoropyrimidine toxicity are closely related to deficient allelic variants of DPYD, but considering the low penetrance and interindividual variability, not all adverse reactions are explained by their presence. In this case, we report a patient with recurrent fluoropyrimidine toxicity without a deficient allelic variant and how this case was managed by the oncologist and cardiologist, considering the need to use fluoropyrimidine in the treatment.

Will nanomedicine become a good solution for the cardiotoxicity of chemotherapy drugs?

Front Pharmacol. 2023 May 4;14:1143361. doi: 10.3389/fphar.2023.1143361. eCollection 2023.

ABSTRACT

Cancer is one of the leading causes of death worldwide, and with the continuous development of life sciences and pharmaceutical technology, more and more antitumor drugs are being used in clinics to benefit cancer patients. However, the incidence of chemotherapy-induced cardiotoxicity has been continuously increasing, threatening patients' long-term survival. Cardio-oncology has become a research hot spot, and the combination of nanotechnology and biomedicine has brought about an unprecedented technological revolution. Nanomaterials have the potential to maximize the efficacy and reduce the side effects of chemotherapeutic drugs when used as their carriers, and several nano-formulations of frequently used chemotherapeutic drugs have already been approved for marketing. In this review, we summarize chemotherapeutic drugs that are highly associated with cardiotoxicity and evaluate the role of nano-delivery systems in reducing cardiotoxicity based on studies of their marketed or R&D nano-formulations. Some of the marketed chemotherapy drugs are combined with nano-delivery systems that can effectively deliver chemotherapy drugs to tumors and cannot easily penetrate the endothelial barrier of the heart, thus decreasing their distribution in the heart and reducing the cardiotoxicity to some extent. However, many chemotherapy nanomedicines that are marketed or in R&D have not received enough attention in determining their cardiotoxicity. In general, nanomedicine is an effective method to reduce the cardiotoxicity of traditional chemotherapy drugs. However, cardiovascular complications in cancer treatment are very complex diseases, requiring the application of multiple measures to achieve effective management and prevention.
