What was measured

The Performance Status Scale for Head and Neck Cancer (PSS-HN) is a clinician-rated evaluation conducted as an unstructured interview format that assesses three functions: Normalcy of Diet , Public Eating (this outcome measure), and Understandability of Speech. Each function is scored from 0 to 100 and analyzed separately. Higher scores indicate better performance status. Treatment effect was analyzed as time-weighted average between baseline (pretreatment) and one year calculated by use of area under the curve (AUC).

Analysis population: Eligible patients who did not withdraw consent, with all 4 assessments: baseline, last 2 weeks of treatment, 3 months, and 12 months.

Groups in this outcome

Standard Fractionation RT + Cisplatin

Standard fractionation radiation therapy with concurrent cisplatin followed by conventional surgery for select patients.

Accelerated Fractionation RT + Cisplatin

Accelerated fractionation radiation therapy by concomitant boost with concurrent cisplatin followed by conventional surgery for select patients.

Group identifiers and denominators belong to this outcome only. They may differ in another outcome or in safety reporting.
