A phase II clinical trial was initiated in 1987 to evaluate a new induction regimen of cis-platinum, 5-fluorouracil, and leucovorin (PFL) for patients with stages III-IV squamous cell carcinoma of the head and neck. Ninety patients were treated and followed for a median duration of 18 months. The median age was 55 and 87% of the patients had stage IV disease. The rates of complete and overall clinical response following three cycles of PFL were 57% and 80%, respectively; the rate of complete response at the primary site was 72%. Eighty-four percent of patients were treated to the primary site with radiation alone (median dose 68 Gy in daily 1.8-Gy fractions) irrespective of the location of the primary site or initial T-stage. The acute tolerance to full-course radiation following PFL was acceptable. The actuarial rate of primary site control for patients treated with radiation was 67% at 36 months. An important prognostic indicator for primary site control was a complete clinical response to induction PFL. For patients who achieved a complete response, radiation or surgery followed by radiation controlled primary site disease equally well at 70%. Patients with a partial response did less well. For these patients, surgery and radiation appeared slightly better than radiation alone.

Desmoplastic squamous cell carcinoma of the tongue simulating myositis or fasciitis.

An unusual form of squamous cell carcinoma of the tongue is reported, the "de novo" submucosal evolution of which is unique. Histologic definition of this malignancy and its distinction from clinically similar benign and malignant conditions are detailed through a brief review of the relevant differential diagnoses. The importance of circumspect diagnostic reassessment when the clinical behavior of a lesion contradicts apparent histologic benignancy is emphasized and treatment inferences are drawn.

Evolving role of surgery after induction chemotherapy and primary site radiation in head and neck cancer.

Chemotherapy, as preliminary treatment before surgery and/or radiation for advanced squamous cell carcinoma of the head and neck, is no longer novel. In prospective trials to date, however, multiple agent induction chemotherapy has yet to demonstrate the initial presumptive promise of improved rates of cure. As an alternate goal, there has emerged a renewed attentiveness toward limiting treatment morbidity, several strategies for which may be considered. Extirpative, often radical, surgery on the primary site of disease usually represents the most significant threat to life quality. Various ways of limiting surgical morbidity will be considered by way of introduction. The trends of head and neck cancer treatment over the decades, leading into the era of induction chemotherapy and refined radiation techniques, will be described. At the combined Dana-Farber/New England Deaconess Head and Neck Oncology Clinic, an experience with over 300 patients receiving induction chemotherapy for advanced head and neck cancer has been analyzed with an emphasis on the postulate of lessening the extent of surgery in appropriately selected patients. In a comparison between trials initiated in 1980 and 1987, improved complete response rates from 26 to 57% were documented. Survival rates were identical, but the use of planned primary site ablative surgery was decreased from 47 to 14%. While some increase in local failure has been noted in patients treated by primary site radiation alone, surgical salvage appeared to be more effective. The implication of these trends for patterns of failure and surgical salvage and data concerning the need for neck dissection in this group of patients will be briefly summarized. Other trials addressing organ-preservation strategies will also be referenced and the dichotomy between survival-based studies and morbidity-limiting studies illustrated. Independent trends in radiation technique as a potential substitute for traditional surgical practice will be reviewed.
