Article Synopsis
  • A study conducted in Greece from February to May 2020 analyzed hospitalized COVID-19 patients, revealing that most subjects were male (65.7%) with an average age of 60, predominantly non-smokers (57.2%).
  • The majority received a standard treatment regimen including hydroxychloroquine and azithromycin, with an average hospital stay of 10 days; 13.3% required intubation and 4.2% died.
  • The findings highlighted that higher neutrophil-to-lymphocyte ratios (NLR) and lactate dehydrogenase (LDH) levels were linked to more severe disease, suggesting these markers may help predict disease progression and inform treatment decisions.

Paraneoplastic syndromes are defined as a combination of clinical disorders associated with malignant diseases that are caused by the secretion of various substances by the tumor without, however, being caused by the direct growth and infiltration of the primary tumor, or due to the development of distant metastases. Despite the fact that lung cancer represents the number one cause of death from cancer worldwide, the new methods of treatment increase patient survival and the incidence of paraneoplastic syndromes. The most important ones of these are humoral hypercalcemia of malignancy, syndrome of inappropriate antidiuretic hormone, hyponatremia of malignancy, ectopic Cushing's syndrome, carcinoid syndrome, and hypoglycemia and are usually a poor prognostic marker.
