Efficacy and safety of immune checkpoint inhibitors (ICIs) combined with antiangiogenic therapy for thymic epithelial tumors (TETs): a retrospective study.

ABSTRACT:

Background

Immune checkpoint inhibitors (ICIs) combined with antiangiogenic therapy have shown promising antitumor activity against a range of advanced cancers. However, evidence is lacking as to whether this combination therapy could benefit thymic epithelial tumors (TETs). We aimed to explore the efficacy and safety of this combination therapy in advanced TETs.

Methods

Ten patients with pathologically proven advanced TETs who received ICIs combined with an antiangiogenic agent from 2020 to 2022 at Zhejiang Cancer Hospital were included in the study. The Kaplan-Meier method was used to compare the treatment efficacy and survival outcomes.

Results

Of the cohort of ten patients who received immunotherapy combined with antiangiogenic targeting drugs, two patients achieved a partial response (PR) with an objective response rate of 20% and seven patients achieved stable disease (SD) with a disease control rate (DCR) of 90%. The median progression-free survival (PFS) was 6.7 months [95% confidence interval (CI): 3.35-8.515] and the median overall survival (OS) was 45.6 months (95% CI: 3.265-88.001). Grade 3 treatment-related adverse events (TRAEs) were only detected in one patient. No grade 4 or above TRAEs were observed.

Conclusions

ICIs in combination with antiangiogenic targeted drugs may be a promising treatment for advanced TETs.

Project description:BackgroundThymomas and thymic carcinoma are thymic epithelial tumors (TETs) of the anterior mediastinum. On the basis of The AJCC 8th Edition of TNM classification, no prognostic prediction model has been established for TETs patients undergoing surgical resection. In this study, based on data from Qilu Hospital of Shandong University, we identified prognostic factors and developed a nomogram to predict the prognosis for TETs patients undergoing extended thymectomy.MethodsPatients with TETs who underwent thymectomy between 2010 and 2020 were consecutively enrolled. An analysis of multivariate Cox regression and stepwise regression using the Akaike information criterion (AIC) was conducted to identify prognostic factors, and a nomogram for TETs was derived from the results of these analyses. The model was validated internally with the Kaplan-Meier curves, ROC curves and calibration curves.ResultsThere were 350 patients with TETs enrolled in the study, and they were divided into a training group (245,0.7) and a validation group (105,0.3). Age, histological type, tumor size, myasthenia gravis, and TNM stage were independent prognostic factors for CSS. The Kaplan-Meier curves showed a significant difference between high nomorisk group and low nomorisk group. A nomogram for CSS was formulated based on the independent prognostic factors and exhibited good discriminative ability as a means of predicting cause-specific mortality, as evidenced by the area under the ROC curves (AUCs) of 3-year, 5-year, and 10-year being 0.946, 0.949, and 0.937, respectively. The calibration curves further revealed excellent consistency between the predicted and actual mortality when using this nomogram.ConclusionThere are several prognostic factors for TETs. Based on TNM stage and other prognostic factors, the nomogram accurately predicted the 3-, 5-, and 10-year mortality rates of patients with TETs in this study. The nomogram could be used to stratify risk and optimize therapy for individual patients.

Project description:BackgroundImmunotherapy offers new hope for cancer patients but presents new medical challenges for healthcare workers in terms of the management of immune-related adverse events (irAEs). The clinical data of two patients with advanced thymoma (T) admitted to the Fujian Cancer Hospital who developed fulminant myocarditis after undergoing immunosuppressant therapy were analyzed retrospectively, and the relevant literature was reviewed. This study aims to examine treatment of thymic epithelial tumors (TETs)-associated immune myocarditis.Case descriptionAn online search was conducted to retrieve relevant full-text articles, and the selected articles were assessed. In total, 13 articles, comprising the data of 113 patients, were included in an analysis to evaluate the efficacy of immunotherapy. Of the 113 patients, 19 had T and 94 had thymic carcinoma (TC). Of the 19 patients with T, 10 (52.6%) achieved a partial response (PR), 8 (42.1%) had stable disease (SD), and 1 (5.3%) had progressive disease (PD). Of the 94 patients with TC, 1 (1.1%) achieved a complete response (CR), 20 (21.3%) achieved a PR, 51 (54.3%) had SD, and 22 (23.4%) had PD. Five articles reported that fulminant myocarditis developed in nine thymic epithelioma patients who were treated with immunosuppressive agents. Two TC patients who presented with fulminant myocarditis were treated with high-dose corticosteroid therapy and underwent pacemaker insertion; none of the patients died of immune myocardial toxicity. However, of the seven T patients who received high-dose corticosteroid therapy and immunoglobulin therapy, and underwent pacemaker implantation, three survived and four died.ConclusionsImmunotherapy has shown promising results in the treatment of patients with refractory or relapsed TETs. Due to their susceptibility to paraneoplastic autoimmunity, TET patients are at a higher risk of developing severe irAEs than patients with other types of cancer. Given the relatively high morbidity and mortality of irAEs, the administration of immune checkpoint inhibitors (ICIs) to treat TETs should be balanced against the clinical response and the precipitation of potentially severe irAEs.
