Neoadjuvant chemotherapy. Neoadjuvant chemotherapy as given in clinical trials has been used to shrink tumors, which renders them more definitively treatable with radiation therapy. Chemotherapy is given prior to the other modalities, hence the designation neoadjuvant to distinguish it from standard adjuvant therapy, which is given after or during definitive therapy with radiation or after surgery. Many drug combinations have been used in neoadjuvant chemotherapy.
Two randomized prospective trials compared combination chemotherapy (i.e., cisplatin, epirubicin, and bleomycin or cisplatin plus fluorouracil [5-FU] infusion) plus radiation therapy to radiation therapy alone.[Level of evidence: 1iiA];[Level of evidence: 1iiDii] Although disease-free survival was improved in the chemotherapy group for both groups, improvement in overall survival was reported only from the Intergroup trial in which chemotherapy with cisplatin was ever concurrently given.
Clinical trials for advanced tumors evaluating the use of chemotherapy before radiation therapy, concomitant with radiation therapy, or as adjuvant therapy after radiation therapy should be considered.[19,20,21,22]
Current Clinical Trials
Check for U.S. clinical trials from NCI's list of cancer clinical trials that are now accepting patients with stage III nasopharyngeal cancer. The list of clinical trials can be further narrowed by location, drug, intervention, and other criteria.
