SD, standard deviation
* Comorbidity Index Score calculated from the Charlson Comorbidity Index (CCI).
** Other primary tumor types were neuroendocrine (N = 1), sarcoma (N = 1), liposarcoma, (N = 1), lymphoma (N = 1) and acute myeloid leukemia (N = 1). Fisher's exact test for categorical data; Mann-Whitney U test for continuous data.
