The Role of Technetium-99m Methoxyisobutyl Isonitrile Scintigraphy in Predicting the Therapeutic Effect of Chemotherapy Against Nasopharyngeal Carcinoma

摘要

Radiation therapy (RT) traditionally has been the standard treatment for patients with nasopharyngeal carcinoma (NPC). Although NPC is radiosensitive, the long-term survival of patients with advanced disease remains poor, and they have a high incidence of locoregional and distant failure.1"4 To improve the prognosis, a variety of treatment regimens have been tested combining chemotherapy and RT in different schemes over the past decade, including induction chemotherapy, concurrent chemotherapy, and adjuvant chemotherapy. However, to date, the best sequence has not been established.
