Abstract

The 1978 Patterns of Care Studies (PCS) survey of carcinoma of the larynx reviewed the process (pre-treatment evaluation and treatment) and outcome of 521 patients. When compared to results from the 1973 PCS survey, several important changes have been observed. The use of surgery in conjunction with radiation therapy (RT) increased in Stage III cases from less than 30% to greater than 60% and in Stage IV cases from 48% to greater than 70%. This change in therapy was associated with a decline in locoregional failure in this patient group. Among Stage I and II supra- and subglottic carcinomas, an improvement in 3-year local tumor control (Stage I: 78 to 100% and Stage II: 54 to 74%) and overall freedom from recurrence (Stage I: 78 to 100% and Stage II: 45 to 73%) was seen over this 5-year period with no identifiable change in process for this subgroup. Also noted was an improvement in the freedom from recurrence rate for Stage III and IV patients receiving treatment at facilities with low process scores. The 1978 PCS survey confirmed the presence of superior patient outcome in several subgroups and the relationship of this improvement to patient process.
