4. In 1984 a study was conducted to determine whether the probability of recovery from stage T3 squamous cell carcinoma of the glottic larynx is different for two well known treatments - surgery and radiation. To study the effects of these treatments on recovery, researchers looked at a SRS of 41 people who had stage T3 squamous cell carcinoma of the glottic larynx and were treated with either surgery or radiation. (Reference: Mendenhall, W. M., R. R. Million, D. E. Sharkey, and N. J. Cassis., 1984) Below is a summary of this data set.
