Clinical trial of weekly paclitaxel chemotherapy for papillary thyroid carcinoma with squamous cell carcinoma component.
Papillary thyroid carcinoma (PC) can occasionally include a squamous cell carcinoma (SCC) component.  In this study, we evaluated the effect of weekly paclitaxel chemotherapy in 3 patients with PC including an SCC component.  None of these patients had lesions of anaplastic carcinoma on pathological examination.  Weekly paclitaxel chemotherapy was performed as an induction chemotherapy for 2 patients.  All 3 patients underwent locally curative surgery and weekly paclitaxel chemotherapy after surgery as an adjuvant therapy.  The response to the chemotherapy was evaluated based on the RECIST guideline (version 1.1).  Two patients had partial responses (PRs) and the remaining 1 had stable disease (SD).  The response rate was 67% and the clinical benefit rate (PR+SD) was 100%.  One patient died of the growth of lung metastases that had been detected before surgery 22 months after the diagnosis.  The remaining 2 are still alive, 14 and 22 months after the diagnosis, respectively.  Taken together, weekly paclitaxel may be one of the effective adjuvant therapies for PC with an SCC component.
