ABSTRACT
INTRODUCTION: Thymic epithelial tumors (TETs) are rare malignancies associated with dysregulation of the immune system and humoral- and cell-mediated immunity abnormalities. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) mRNA vaccine is effective in preventing coronavirus disease 2019 morbidity and mortality. The aim of this study was to evaluate the seroconversion in patients with TET after two doses of mRNA vaccine. METHODS: This is a prospective study in which consecutive patients with TET were enrolled before receiving the first dose of SARS-CoV-2 mRNA vaccine (BNT162b2 by Pfizer-BioNTech). SARS-CoV-2 spike-binding immunoglobulin (Ig)G antibody serologic levels were analyzed at different time points, including before first vaccine dose (T0), 1 month after the second dose (T2), and 3 months after the second dose (T3). RESULTS: Overall, 39 patients were included in the analysis. All patients had negative antibody titer results at T0. There were 19 patients (48.7%) in the follow-up with no residual tumor lesion/s (referred as no evidence of disease), and 20 (51.3%) had evidence of disease (ED) and were receiving systemic treatment. Dysregulations of the immune system were diagnosed in 29 patients (74.4%) with Good syndrome (GS) being the most frequent immune disorder (48.7%). At univariate analysis, lack of seroconversion at T2 was significantly associated with ED (p < 0.001) and with GS (p = 0.043). A significant association with impaired seroconversion was confirmed at multivariate analysis for ED (p = 0.00101) but not for GS (p = 0.625). CONCLUSIONS: Our data revealed that patients with TET with ED had substantially higher probability of impaired seroconversion after SARS-CoV-2 mRNA vaccine as compared with patients with no evidence of disease.

Major associations of medical oncologists remark that novel anticancer treatments should guarantee improvement of survival outcomes as well as of patients' quality of life (QoL). Herein, we investigated QoL assessment and reporting in phase III randomized controlled trials (RCTs) testing new drugs in metastatic non-small cell lung cancer (NSCLC), published between 2010 and 2021. We selected 172 RCTs for further analysis. Only 2/172 (1.2%) trial included QoL among primary study endpoints. Of note, 40/172 (23.3%) trials did not include QoL assessment among endpoints. The majority of RCTs (102/172, 59.3%) did not report QoL results in primary publications. Particularly, RCTs testing immunotherapy, target therapy and chemotherapy did not disclose QoL data in primary publications in 97.0%, 51.5% and 46.5% of cases, respectively. Next, we found that only 43/95 (45.3%) positive studies reported QoL results in primary articles. Of the 102 trials missing QoL data in primary manuscripts, only 21 (20.6%) disclosed QoL results in a secondary publication. Finally, we found a common fail in adherence to CONSORT-PROs items in publications reporting QoL results. In summary, our study reveals a relevant inadequate assessment and under-reporting of QoL in RCTs of novel systemic treatments for patients with metastatic NSCLC.
