Concurrent Chemoradiotherapy With Weekly Low-Dose Cisplatin for Japanese Patients With Head and Neck Squamous Cell Carcinoma.


ABSTRACT:

Background

Concurrent chemoradiotherapy (CCRT) with tri-weekly high-dose cisplatin (HDC) is considered the standard regimen. However, due to significant toxicity, various weekly low-dose schedules have been increasingly used. We investigated the tolerability and survival of patients with head and neck squamous cell carcinoma (HNSCC) who underwent CCRT with low-dose weekly cisplatin (LDC) for Japanese population.

Methods

A retrospective review was conducted among patients with HNSCC who were treated with CCRT/LDC in our institute. Ninety-five patients who met the criteria were enrolled in this study. We evaluated the cycle and cumulative cisplatin dose, completion rate of radiotherapy, adverse events, and survival outcome.

Results

The mean cycles and cumulative cisplatin dose were 4.7 cycles and 187 mg/m2. All patients completed planned dose of radiation without prolonged breaks. Leucopoenia was the most frequent dose-limiting factor and 44% patients developed grade 3 or 4 toxicity. The 2-year overall survival and recurrence-free survival were 93% and 74%, respectively. The significant differences of survival outcomes between the patients with total cisplatin dose (⩾200 mg and <200 mg) or among age distribution (35-55, 56-75, and ⩾76) were not observed.

Conclusions

Concurrent chemoradiotherapy/LDC can be safely administered with acceptable toxicity and survival outcome even if the patients with higher age, lower eGFR, and so on.
