CD271 (cluster of differentiation 271) is a transmembrane protein (gene encoded on 17q21.33) belonging to the tumor necrosis factor receptor superfamily, which plays both positive and negative roles in the development of several types of cancer. Due to such poor prognoses of patients with HNSCC, the search for new treatment strategies is imperative. Approximately 10% of N0–N1 carcinomas and 30% of N2–N3 tumors form distant metastases. Cancer relapse and the appearance of distant metastases worsen the prognosis. HNSCC is associated with lower survival rates and is responsible for the second highest cancer-related mortality rate. Head and neck squamous cell carcinoma (HNSCC) is the most common cancer entity of the upper aerodigestive tract and the sixth most common cancer worldwide.
We conclude that CD271 is a promising candidate that provides prognostic information for HNSCC and could be a putative target for HNSCC treatment. However, neither TrkA nor TrkB expression were linked to prognosis or cell proliferation. The CD271 inhibitor LM11A 31 suppressed cell motility in vitro. In vitro, CD271 expression marked a subpopulation with higher proliferation rates, but proliferation was lower in tumor cells that co-expressed CD271 and TrkC. However, the human carcinomas that also expressed TrkC had a reduced correlation with distant metastases and better survival rates. High expression of CD271-positive cells predicted a bad clinical outcome of patients with HNSCC and was associated with distant metastases. The vast majority of tumors exhibited CD271 and TrkA, whereas only half of the tumors expressed TrkB and TrkC. CD271 and Trks were heterogeneously expressed in human HNSCC. A retrospective study and functional in vitro cell line tests (migration assay and cell sorting) were conducted in order to evaluate the relevance of CD271 expression alone and with regard to Trk expression. Neurotrophins that bind to CD271 also have a high affinity for the tropomyosin receptor kinase family (Trk), consisting of TrkA, TrkB, and TrkC, which must also be considered in addition to CD271. The present study investigated the role of the low affinity nerve growth factor receptor CD271 as a putative therapy target in HNSCC.
