Objective: To identify the relative importance of several clinical variables present at intensive care unit admission on the short- and long-term mortality of critically ill patients with cancer after unplanned intensive care unit admission.

Methods: This was a retrospective cohort study of patients with cancer with unplanned intensive care unit admission from January 2017 to December 2018. We developed models to analyze the relative importance of well-known predictors of mortality in patients with cancer admitted to the intensive care unit compared with mortality at 28, 90, and 360 days after intensive care unit admission, both in the full cohort and stratified by the type of cancer when the patient was admitted to the intensive care unit.

Objective: Pleomorphic adenoma (PA), mucoepidermoid carcinoma (MEC), and adenoid cystic carcinoma (ACC) are the most prevalent salivary gland tumors. Their pathogenesis has been recently associated with complex molecular cascades, including the TGFβ signaling pathway. The aim of this study was to evaluate the expression of genes associated with the TGFβ signaling pathway (TGFB1, ITGB6, SMAD2, SMAD4, FBN1, LTBP1, and c-MYC) to map possible downstream alterations in the TGFβ cascade.

Background And Objectives: Acute kidney injury (AKI) has emerged as an important toxicity among patients with advanced cancer treated with immune checkpoint inhibitors. The aim of this study was to describe the incidence, risk factors and mortality of AKI in patients receiving immune checkpoint inhibitors alone or in combination with another form of immunotherapy or chemotherapy.

Design, Setting And Participants: We included all patients who received immune checkpoint inhibitors alone or in combination with another form of immunotherapy or chemotherapy at AC Camargo Cancer Center from January 2015 to December 2019.

Aims: Extraskeletal osteosarcoma (ESOS) is a malignant tumour developing in soft tissues, characterised by the production of osteoid or bone matrix by tumour cells. The standard treatment for localised ESOS is wide resection. Radiotherapy and chemotherapy are usually incorporated into the management of patients.
