[Cisplatin-fluorouracil chemotherapy in epidermoid cancers of glottic origin staged as T2].

A retrospective analysis of 94 patients presenting well-differentiated untreated invasive glottic squamous cell carcinomas, staged as T2 according to the 1987 Union Internationale contre le Cancer staging classification system, managed at our institution from March 1982 to April 1991 with cisplatin-fluorouracil neo-adjuvant chemotherapy, was conducted. Following neo-adjuvant chemotherapy, partial laryngeal surgery, and radiation therapy were performed in 85.1% (80/94) and 4.2% (3/94) of cases, respectively. Perioperative chemotherapy (fluorouracil) and postoperative chemotherapy (cisplatin-fluorouracil) was performed in 68.7% (55/80) and 63.7% (51/80) of patients who underwent surgery, respectively. Following neoadjuvant chemotherapy, one patient (1.1%) refused any form of treatment, and "exclusive" chemotherapy was performed in 9.6% (9/94) of cases. A 3-year follow-up was always achieved and 66 patients (70.2%) presented with a 5-year follow-up. A complete clinical response was achieved in 32.9% of cases following neo-adjuvant chemotherapy. A complete histological response was noted in 31.2% (25/80) of patients treated with partial laryngeal surgery following neo-adjuvant chemotherapy. A strong statistical relation was noted between complete clinical response and complete histological response (p < .0001). Chemotherapy related death never occurred in our series however chemotherapy related toxicity lead to reduction in the drug dosages and chemotherapy arrest in 14.3% and 3.6% of cases, respectively. The Kaplan-Meier 5-year survival, local recurrence, nodal recurrence, distant metastasis, and second primary estimate was 84.9%, 8.4%, 1.1%, 2.2%, and 10%, respectively. The overall local recurrence rate varied from 25% following neo-adjuvant chemotherapy and radiotherapy, to 33.3% following "exclusive" chemotherapy, and 3.7% following neo-adjuvant chemotherapy and partial laryngeal surgery. Overall local control and laryngeal preservation was achieved in 98.9% and 97.8% of patients respectively. Our data suggests that the use of neo-adjuvant cisplatin-fluorouracil induction chemotherapy deserves further consideration in the management of glottic carcinomas staged as T2.
