Abstract

The Coronavirus disease 2019 (COVID-19) pandemic impacts pulmonary cancer management since it shares similar clinical features and creates fear among patients to visit hospitals due to possible in-hospital disease transmission. We report a patient who presented with a rare case of a pulmonary neuroendocrine tumor with an ocular involvement, which, unfortunately, experienced a delay in diagnostics. The first hospitalization was due to superior vena cava syndrome, pleural and pericardial effusions, and swollen left eye. The patient was diagnosed with pulmonary cancer, released after the symptoms were relieved, and expected to visit a referral hospital for further diagnostics and treatments. The patient returned two weeks later with progressing disease, an ocular metastasis, and a reactive serum IgM/IgG to SARS-CoV-2; serial qPCR tests consistently returned negative. The patient was treated with the best supportive care before succumbing to death. Biopsy showed pulmonary tumor cells consistent with a neuroendocrine tumor. Fear of the pandemic makes patients reluctant to seek help from medical facilities. Pulmonary TBC has similar symptoms to pulmonary cancer, which can pose another challenge in diagnosing pulmonary cancer in TB-endemic countries. Thus, patients often present with advanced-stage pulmonary cancer with rare ocular metastasis, as in this report.

Abstract

ABSTRACTEvaluation of changes in antibody orders is a common exclusion in vaccination strategies because of the method ofanalysis. The fact that protection by antibodies produced by the Severe Acute Respiratory Syndrome Coronavirus-2(Sars-Cov-2) infection both naturally and through vaccines will decrease in less than one year, is a challenge for acountry with a large population like Indonesia to run its vaccination program. The main challenge is whether thevaccination strategy adopted will overcome the vaccine barrier and the race between the rate of vaccination and therate of viral mutation and antibody reduction. In addition to antibodies, the adaptive immune system is also run by Tcells that are included in the cell-mediated immune system (CMI) group. In patients with asymptomatic or mildsymptoms of Coronavirus 2019 (Covid-19), T and CMI responses are known to appear in some patients who are notknown to have been exposed to Sars-Cov-2 before. This evidence suggests that the adaptive catastrophe for SarsCov-2 has been acquired by ordering memory T cells and may last longer than previously thought. For countries withlarge populations, this will certainly help overcome the limitations of vaccines and the time needed to implement theirvaccination strategies.
