Summary

The purpose of this study is to To confirm the predictive value of CCND1 for TPF induction in cN2 patients with OSCC

Description

Induction chemotherapy is regarded as an effective way to reduce or downgrade the locally advanced or aggressive cancers, and to improve the chance of eradication of the locoregional lesions by radical surgery and/or radiotherapy. However, there are still debates on the clinical value of induction chemotherapy for patients with advanced and resectable oral squamous cell carcinoma. A prospective, open label, parallel, interventional, randomized control trial on TPF induction chemotherapy indicate there is no difference in overall survival, disease free survival, local regional recurrence free survival and metastasis free survival between experimental group and control group, however, the subgroup analysis proves that the induction chemotherapy of TPF protocol could benefit the patients with cyclinD1 high expression and cN2 locally advanced oral squamous cell carcinoma. Zhong et al, Randomized Phase III Trial of Induction Chemotherapy With Docetaxel, Cisplatin, and Fluorouracil Followed by Surgery Versus Up-Front Surgery in Locally Advanced Resectable Oral Squamous Cell Carcinoma, J Clin Oncol 2013The previous study was registered at ClinicalTrials.gov website with NCT01542931 identification number.This prospective, interventional, randomized control trial was to evaluate the TPF induction chemotherapy have a better effects in the cyclin D1 high expression and cN2 patients with locally advanced and resectable OSCC. The patients would receive TPF induction chemotherapy followed by radical surgery and post-operative radiotherapy (the experimental group) or radical surgery and post-operative radiotherapy (the control group). The primary endpoint is overall survival and the second endpoint is local control and distant control.The study had a power of 80% on the basis of an assumed 2-year survival rate of 67% in the experiment group and 25% in the control group, with use of a two-sided log-rank test at a level of significance of 0.05. The recruitment period would be 2 years, and the follow-up period would be 2 years, and 15% of patients would drop out early or be lost to follow-up. A maximum of 24 patients per group were to be recruited with stplan 4.5 software calculation. Department of Biostatics, MD Anderson Cancer Center, University of TexasUSAThe patients in the experimental group received the TPF induction chemotherapy for 2 cycles followed by radical surgery and post-operative radiotherapy. The palpable edges of the primary lesion (both the longest and shortest axis) were marked before induction chemotherapy by at least four points, which were 0.5cm away. The patients in the control group received the radical surgery and post-operative radiotherapy.

Induction chemotherapy: For the patients who were randomly assigned to receive TPF induction chemotherapy, peripherally inserted central catheter was firstly inserted before intravenous infusion, docetaxel(at a dose of 75mg/m2 of body surface area) was administered as a 2-hour intravenous infusion, followed by intravenous cisplatin(75 mg/m2), administered during a period of 2 to 3 hours. Then, 5-Fu(5 - Fluorouracil) (750 mg/m2/day) was administered as a 120-hour continuous intravenous infusion for 5 days. Induction chemotherapy was given every 3 weeks for 2 cycles, unless there was disease progression, unacceptable toxic effects, or withdrawal of consent by the patients. Dexamethasone was given before docetaxel infusion to prevent docetaxel-related hypersensitivity reactions, skin toxic effects, and fluid retention; prophylactic antibiotics were also given starting on day 5 of each cycle for 3 days. Hydration with diuretic and antiemetic treatment was also performed. Primary prophylaxis with recombinant granulocyte colony-stimulating factor was not suggested. Chemotherapy dose reductions were allowed for grade 3/4 toxicities occurring after cycle 1: 25% and 50% dose reductions of the three chemotherapy agents were suggested for grade 3 and grade 4 hematologic toxicities or gastrointestinal toxicities, respectively; 25% and 50% cisplatin dose reductions were suggested for grade 3 and grade 4 renal toxicities, respectively. Surgery was performed at least 2 weeks after completion of induction chemotherapy.

Surgery: Radical resection of the primary lesion and full neck dissection(functional or radical) with proper reconstruction(pedicle or free flap) were performed. The safety margins of the primary lesion were 1.0-1.5cm far away from the palpable margins of the lesion; for patients who received induction chemotherapy, the safety margins were 1.0cm away from the marks that were placed before induction chemotherapy, to ensure the same extent surgery in both arms. Frozen sections during surgery were performed to confirm adequate margins.

Post-operative radiotherapy: Radiotherapy was arranged 4 to 6 weeks after surgery. Routine external beam radiotherapy, such as conformal or intensity modulated radiotherapy was performed, and the dose was 1.8-2 Gy/day, 5 days/week for 6 weeks, and totally 54-60 Gy, in the patient with high risk features, such as positive surgical margin, extra capsular nodal spread, vascular embolism, concurrent chemotherapy with cisplatin 80mg/m2 was suggested.

A complete medical history was obtained and tumor assessment was performed at baseline. Clinical tumor response was assessed by clinical evaluation and imaging study and was characterized according to the criteria of response evaluation criteria in solid tumors (version 1.1) before surgery. Post-operative pathologic response was assessed by post-operative pathologic examination as good and bad response. A good response was defined as absence of any tumor cells (pathologic complete response) or presence of scattered foci of a few tumor cells (minimal residual disease with <10% viable tumor cells); otherwise, a bad pathologic response was defined. Toxic effects were assessed weekly during and after completion of induction chemotherapy and radiotherapy according to the common terminology criteria for adverse events (version 3.0).

Overall survival was calculated from the date of randomization to the date of death; disease free survival was calculated from the date of randomization to tumor recurrence or distant metastasis or death from any cause; locoregional recurrence/distant metastasis free survival was calculated from the date of randomization to locoregional recurrence/distant metastasis of tumor or death from any cause. Time to locoregional recurrence/distant metastasis was calculated from the date of finishing treatment to tumor locoregional recurrence/distant metastasis. Patients were monitored by every three months in the first two years, every six months in the next 2 years, and once a year thereafter until death or data censoring.
