Spots Global Cancer Trial Database for Cyclophosphamide for Nasopharyngeal Carcinoma

Study Description

Brief Summary: There is no standard third-line systemic treatment for inoperable locoregionally advanced recurrent or metastatic nasopharyngeal carcinoma (NPC). We investigated the efficacy and safety of metronomic oral cyclophosphamide as third-line treatment or beyond.

Detailed Description: NPC is endemic in Southern China including Hong Kong. Despite aggressive definitive chemoradiotherapy for locoregionally advanced disease, still about 30% develop relapse locoregionally or distally. Salvage or second-course radical radiotherapy with or without chemotherapy may achieve durable disease control for locoregionally advanced recurrent disease. However for those who had received 2 courses of radical radiotherapy or those with distant metastases, systemic chemotherapy would be the only drug of choice. Platinum-based doublet chemotherapy including cisplatin + 5-fluorouracil, capecitabine, gemcitabine or taxane is considered the standard first-line treatment. For second-line treatment, whether platinum-based chemotherapy was given previously is a consideration. Re-challenge with cisplatin and 5-fluorouracil can be considered in patients who enjoyed a good initial response to the same regimen with an intervening disease-free period of more than 1 year.However so far there has been no recognized standard third-line systemic treatment. Metronomic oral chemotherapy may provide an ideal choice patients treated in this setting by shifting the targets from tumor cells to tumor vasculature so as to reduce the chance of drug resistance as well as offering a relatively low toxicity profile to them who have been significantly jeopardized by the long-term complications brought prior courses of radiation therapy, surgery and chemotherapy. In view of the above, we investigated metronomic open-label oral cyclophosphamide as third-line treatment or beyond in patients with inoperable locoregionally advanced recurrent or metastatic NPC who had failed at least 2 lines of prior systemic chemotherapy.
