Clinical Trial: Induction Docetaxel/Cisplatin/5-fluorouracil (TPF) as Selector for Chemo Radiation Therapy (RT) Versus Partial Laryngectomy in Advanced Laryngeal Cancer
Study Status: Recruiting
Recruit Status: Unknown status
Study Type: Interventional
Official Title: Phase II Organ Preservation Trial Using Cisplatin Concomitant With Radiation Therapy in Advanced Laryngeal Cancer Patients Who Have Responded to Induction Chemotherapy With Taxotere, Cisplatin, and 5-
Brief Summary: Treatment of patients with one cycle of induction chemotherapy to select for organ preservation of the larynx has been proven as a standard approach. When compared to historical controls. The investigators propose to study patients with a similar treatment strategy (i.e. one cycle of induction chemotherapy followed by two more chemotherapy cycles, in advanced nodal disease, followed by chemoradiation for those responding to the initial chemotherapy. Those who fail to respond or fail in radiation will directly undergo surgery. The novelty of the proposed study is that non responders and failures will be given the opportunity of larynx preserving supracricoid laryngectomy. The investigators will attempt to reduce toxicity from induction chemotherapy and improve potency with the use of docetaxel/cisplatin/5-fluorouracil (TPF) in place of the standard regimen of cisplatin and 5-fluorouracil (PF). Emerging data demonstrates that induction regimens containing triplets with platinum, 5-fluorouracil, and taxanes produce higher response rates and less overall toxicity when compared to induction strategies utilizing PF
Detailed Summary:
The optimal treatment of patients with laryngeal cancer remains controversial. Standard treatment options have included laryngectomy with or without radiation (RT) and radiation alone with surgical salvage (RTSS).
Because of the significant functional morbidity associated with laryngectomy, the Department of Veterans Affair Cooperative Studies Program completed a randomized, prospective study of 332 patients that compared a new organ preservation treatment strategy to conventional laryngectomy and radiation. The experimental treatment arm involved three cycles of neoadjuvant chemotherapy followed by definitive radiation among patients who had a partial (>50%) clinical tumor response. Final results of this study demonstrated comparable 2, 3, 4, and 10 year survival rates between treatment groups, with successful laryngeal preservation in 66% of the surviving patients randomized to receive neoadjuvant chemotherapy.
This study led to a dramatic re-assessment of the treatment approach for advanced laryngeal and hypopharyngeal cancer patients, who face total laryngectomy. Based on these results, Second approach was designed and tested in a Phase II study at the University of Michigan .In this study, 97 patients were treated with one cycle of induction chemotherapy. Seventy-five percent had a >50% reduction of tumor and were treated with chemo-RT (cisplatin 100 mg/m2 x 3 cycles), and 25% were non-responders who underwent total laryngectomy followed by RT. The overall 3-year survival rate was 85%,and the larynx preservation rate was 70%. This study included over 30 percentage of patients with advanced stage 4 disease, however did not specifically evaluate there outcome and therefore did not directly address the role of organ preservation in advanced disease which is considered a controversial issue in head and neck literatu
