Background

The standard of care for locally advanced head and neck squamous cell carcinoma (HNSCC) is combination chemoradiotherapy. Platinum-based chemotherapy is used for radiosensitization and significantly improves locoregional control and survival. Cisplatin is the standard of care; however, many patients are cisplatin-ineligible due to underlying comorbidities. Carboplatin is an alternative chemotherapy in these patients, but efficacy data are lacking. Purpose: To evaluate the efficacy and tolerability of weekly carboplatin concurrent with radiation in veterans with locally advanced HNSCC.

Methods

Our tumor registry was used to identify patients who received platinum-based chemoradiotherapy for stage III-IVB HNSCC at a single center between 2007 to 2017. Patients who received carboplatin were identified. Data including dosing, toxicities, and disease response was collected and analyzed.

Results

A total of 26 patients who received weekly carboplatin were analyzed. All patients were male with an average age of 65. A usual dose of carboplatin AUC 2 was utilized. The average cumulative dose for weekly carboplatin was AUC 12, with most patients (65%) receiving 6 doses or more. The mean number of weekly carboplatin doses held was 0.3. 7 patients (27%) had at least one dose held. 21 (81%) patients showed treatment benefit: 19 (73%) had complete response and 2 (8%) had partial response on first scan following treatment. The four most common toxicities were mucositis (69%), nausea/vomiting (23%), oral thrush (19%), and dermatologic toxicities (19%). The most common toxicities causing dose interruption were fatigue (12%), neutropenia (8%), and thrombocytopenia (8%). Grade 3/4 mucositis was experienced in 6 patients (23%). Other grade 3/4 toxicities included neutropenia (8%), anemia (8%), thrombocytopenia (1%), nephrotoxicity (1%) and nausea (1%).

Conclusions

Carboplatin was both efficacious and well tolerated in our older veteran population. These findings add to the limited body of evidence examining weekly carboplatin in patients with advanced head and neck cancer. While cisplatin remains standard of care, carboplatin may be a reasonable alternative as evidenced in a real-world veteran population.
