To test for rates of inpatient palliative care (IPC) in metastatic testicular cancer patients receiving critical care therapy (CCT). Within the Nationwide Inpatient Sample (NIS) database (2008-2019), we tabulated IPC rates in metastatic testicular cancer patients receiving CCT, namely invasive mechanical ventilation (IMV), percutaneous endoscopic gastrostomy tube (PEG), dialysis for acute kidney failure (AKF), total parenteral nutrition (TPN) or tracheostomy. Univariable and multivariable logistic regression models addressing IPC were fitted.

Background: Historic evidence suggests that non-Caucasian race/ethnicity predisposes to higher testis cancer-specific mortality (CSM) in non-seminoma. However, it is unknown, whether higher CSM in non-Caucasians applies to Hispanics or Asians or African-Americans, or all of the above groups. In contemporary patients, we tested whether CSM is higher in these select non-Caucasian groups than in Caucasians, in overall and in stage-specific comparisons: stage I vs.
