Feasibility of concurrent chemoradiotherapy with high-dose cisplatin after induction TPF chemotherapy in head and neck cancer: a critical review of the literature and the experience of the European Institute of Oncology

摘要

Many concerns are related to the idea that the acute toxicity of induction chemotherapy (IC) performed with TPF (docetaxel, cisplatin, 5-fluorouracil) could reduce the ability to deliver the subsequent standard concurrent chemoradiotherapy (CRT) in head and neck cancer patients. We performed a critical review of the literature on the toxicity profile of the standard CRT administered after the IC with TPF. A total of 13 papers (including 950 patients) were selected. Results showed that most patients were treated with an adequate radiation total dose although a significant proportion of them (from 15 to 30%) completed the planned treatment with a delay of more than 5 days. A minority of patients were able to be treated with three cycles of concurrent cisplatin, but only few papers reported how many of patients reached the cumulative total dose of almost 200 mg/m(2) cisplatin. The rate of deaths due to treatment-related toxicity varied from 0 to 9% (median and mean 2%). Two prospective trials stopped patient enrollment due to acute treatment-related toxicity and because a low number of patients were able to undergo the planned full schedule of cisplatin during the CRT, respectively. Retrospective analysis of 45 patients treated at our institute showed that this schedule was feasible with manageable side effects. In conclusion, the literature data did not provide homogeneous information on the feasibility of the standard CRT after induction TPF. A more uniform data collection of treatment-related toxicity will be helpful in better selecting the patients who might adequately tolerate this multimodality strategy.
