Induction Versus Adjuvant Gemcitabine/Cisplatin in Locally Advanced Non-metastatic Nasopharyngeal Carcinoma

Summary

The standard of care for locally advanced nasopharyngeal carcinoma is radical chemoradiation(CRT).Recent advances in radiation techniques and supportive measures resulted in improvemnent of locoregional control and quality of life.However distant failure is still the main challenging reason of poor survival Addition of systemic therapy to concurrent CRT is widely used and accepted as an option to reduce these failures ,however selection of chemotherapy regimen and timing in relation to CRT is controversial. Doublet and triplet chemotherapy regimens using cisplatin and 5FU are throughly investigated in this setting.Inspite of significant improvement in disease free survival and overall survival they were poorly tolerated.Hence,minority of patients in the daily practice could tolerate those studied regimens as propsed. Recently, in multicenter randomized trial, Zhang and his group investigated gemcitabine and cisplatin as induction chemotherapy (ICT) added to CRT.It showed improvement in recurrence free survival and overall survival.More importantly 96.7% of the experimental arm completed the treatment protocol. This was further confirmed by an updated network of meta analysis by Bongiovanni et al.Again the question of "when" is still valid.Our proposal is to compare tolerable regimen in induction versus adjuvant settings.
