We evaluated the usefulness of L-dopa decarboxylase (DDC) as a tumor marker of neuroendocrine (NE) cell differentiation by measuring its expression in 432 human tumors of diverse types and origins. A subset of these tumors and cell lines derived from them also were studied for expression of two
We evaluated the feasibility and usefulness of reverse transcriptase-polymerase chain reaction (RT-PCR) on fine-needle aspirates for categorization of small blue round cell tumors (SBRCTs). A total of 51 cases, including 25 Ewing sarcoma/peripheral primitive neuroectodermal tumors (PNETs), 11
The differential diagnosis of neuroblastoma from other small round-cell tumors of childhood, although clinically of great importance, is sometimes difficult due to the almost indistinguishable appearance of such tumors by conventional microscopy. Because neuroblastomas are characterized by the
