Molecular Targeted Therapy in the Management of Recurrent and Metastatic Nasopharyngeal Carcinoma: A Comprehensive Literature Review
Nasopharyngeal carcinoma (NPC) is the most frequent malignancy arising in the nasopharynx. NPC, to a larger degree, substantially differs from the other malignancies of the head and neck, in terms of incidence, etiology, risk factors, molecular pathogenesis, clinical behavior, management and prognos...

description | Nasopharyngeal carcinoma (NPC) is the most frequent malignancy arising in the nasopharynx. NPC, to a larger degree, substantially differs from the other malignancies of the head and neck, in terms of incidence, etiology, risk factors, molecular pathogenesis, clinical behavior, management and prognosis. Fundamentally, the management of NPC is entirely guided by the disease stage. Favorably, patients with early- stage disease have encouraging survival outcomes with stand-alone radiation therapy (RT), specifically following the emergence of intensity-modulated RT (IMRT). The reported five-year local control rates are outstanding, and they range from 70% to 90%. Unfortunately, around one-third (30%) of patients presents with loco-regional or distant recurrences, despite rigorous curative treatment in the intermediate (stage II) and advanced (stage III-IVB) NPC disease. At the present time, the management of recurrent and metastatic NPC is largely discouraging and presents significant challenges to the treating physicians. Broadly speaking, there are three management schemes utilized in the management of recurrent and metastatic NPC, namely: (i) palliative systemic chemotherapy, (ii) molecular targeted therapy, and (iii) immunotherapy. The goal of this study is to holistically review the existing body of literature on the utility and safety of molecular targeted therapy in the management of patients with recurrent and metastatic NPC, with a special focus on vascular endothelial growth factor (VEGF) and epidermal growth factor receptor (EGFR) targets. |
