ABSTRACT
In this particular case study, we present a 66-year-old male who was diagnosed with an atrial myxoma eight years after receiving treatment for non-small cell lung cancer. The patient underwent chemo-radiotherapy (mediastinal area) in 2012 to address stage III-A adenocarcinoma of the lung. During follow-up imaging in 2020, a left atrial mass displaying characteristic features of a cardiac myxoma was detected. Upon reviewing a computed tomographic (CT) scan from 2017 within the previously irradiated mediastinal region, the cardiac mass was retrospectively identified. The surgical excision of the cardiac mass was performed, and a subsequent pathological examination confirmed the diagnosis of myxoma. To the best of our knowledge, this is the first reported case of a left atrial myxoma in a patient previously treated for adenocarcinoma of the lung and the first instance of an atrial myxoma occurring in a site that had undergone prior radiation therapy.
ABSTRACT
ABSTRACT: The COVID-19 pandemic, caused by the SARS-CoV2 virus, has infected millions worldwide with cancer patients demonstrating a higher prevalence for severe disease and poorer outcomes. Recently, the BNT162b2 mRNA COVID-19 vaccine was released as the primary means to combat COVID-19. The currently reported incidence of local and systemic side effects was 27% in the general public. The safety of the BNT162b2 mRNA COVID-19 vaccine has not been studied in patients with an active cancer diagnosis who are either ongoing or plan to undergo oncologic therapy.This single center study reviewed the charts of 210 patients with active cancer diagnoses that received both doses of the BNT162b2 mRNA COVID-19 vaccine. The development of side effects from the vaccine, hospitalizations or exacerbations from various oncologic treatment were documented. Type of oncologic treatment (immunotherapy, chemotherapy, hormonal, biologic, radiation or mixed) was documented to identify if side effects were related to treatment type. The time at which the vaccine was administered in relation to treatment onset (on long term therapy, within 1 month of therapy or prior to therapy) was also documented to identify any relationships.Sixty five (31%) participants experienced side effects from the BNT162b2 mRNA COVID-19 vaccine, however most were mild to moderate. Treatment protocol was not linked to the development of vaccine related side effects (Pâ=â.202), nor was immunotherapy (Pâ=â.942). The timing of vaccine administered in relation to treatment onset was also not related to vaccine related side effects (Pâ=â.653). Six (2.9%) participants were hospitalized and 4 (2%) died.The incidence of side effects in cancer patients is similar to what has been reported for the general public (31% vs 27%). Therefore, we believe that the BNT162b2 mRNA COVID-19 vaccine is safe in oncologic patients undergoing numerous cancer treatments.

Immune checkpoint inhibitors are immune stimulatory drugs used to treat many types of cancer. These drugs are antibodies against inhibitory proteins, such as CTLA-4 and PD-1/PD-L1, that are expressed on immune cells. When bound, they allow for increased stimulation of T cells to fight tumor cells. However, immune checkpoint inhibitors have several immune-related adverse effects. Many cases have come to light recently of cardiotoxicity as a result of treatment with these drugs. Cardiotoxicity from immune checkpoint inhibitors is unique due to its rarity and high mortality rate. Patients with this toxicity may present with myocarditis, pericarditis, Takotsubo cardiomyopathy, conduction disorders, and others within just a few weeks of starting immune checkpoint inhibitors. We present here a review of the current research on immune checkpoint inhibitors, their associated cardiotoxicities, the timing of presentation of these conditions, lab tests and histology for each condition, and finally the treatment of patients with cardiotoxicity. We observe a positive skew in the onset of presentation, which is significant for the treating physician.
ABSTRACT
The new era of cancer treatments has made immune checkpoint inhibitors (ICIs) and emerging multikinase inhibitors (TKIs) the standards of care, thus drastically improving patient prognoses. Pembrolizumab is an anti-programmed cell death-1 antibody drug, and lenvatinib is a TKI with preferential antiangiogenic activity. We present, to our knowledge, the first reported series of cases consisting of patients with metastatic non-small cell lung cancer and malignant pleural mesothelioma who were treated with several types of chemotherapy combinations and ICIs followed by disease progression. They were subsequently treated with combined immunotherapy and TKI treatment, resulting in a near complete response within a very short time. Clinical responses were supported by in vitro testing of each patient's lymphocytic response to pembrolizumab after pre-exposure of target cancer cells to lenvatinib.
ABSTRACT
In the present case study, we describe a 53-year-old male with an aggressive small cell lung cancer (SCLC) that was diagnosed in January 2019. Our patient was treated as first line of systemic chemotherapy consisting of cisplatin and etoposide followed by mediastinal prophylactic radiotherapy with good response later he received for his metastatic disease (M-SCLC) a rechallenge of systemic chemotherapy consisting of carboplatin, etoposide and dulvalumab with stable disease and after progression his disease he was treated with lurbinectedin and after four cycles he reached a complete radiologic response. To the best of our knowledge, this is the first case to be reported of M-SCLC patient treated with prior of two types of platinum combination with immunotherapy and reaching a complete radiologic response.

In this report, we aim to present a case of pulmonary toxicity in a patient that received neoadjuvant chemotherapy treatment with doxorubicin and cyclophosphamide for triple-negative breast cancer that was followed with granulocyte colony-stimulating factor (G-CSF) for prevention neutropenia, our patient presented with chest discomfort and dyspnea, with radiologic evidence of radiologic investigations showed acute respiratory distress syndrome, after investigation and follow up we came to the conclusion that it was G-CSF adverse effect.

We aim to describe two cases of creatine phosphokinase (CPK) and liver enzymes elevation occurring as adverse effects of alectinib (Alecensa) treatment for anaplastic lymphoma kinase (ALK)-mutated metastatic nonsmall cell lung cancer (NSCLC). A 56-year-old female and a 59-year-old male diagnosed with NSCLC exhibiting ALK gene rearrangements were treated by alectinib administration. The former had a complete response of widespread metastatic disease within 3 months, and the latter also had a substantial response. Both patients initially experienced an episode of CPK elevation and neither had dose modifications. At the end of the treatment, CPK and liver enzymes returned to normal range despite the continuation of alectinib full dose. A transient elevation of CPK and liver enzymes may take place during the alectinib treatment, indicating a tumor tissue damage thus contributing to a significant response.
