In Regard to Shaverdian et al

Abstract

To the Editor: The study by Shaverdian et al ( 1 Shaverdian N. Gondi V. Sklenar K. et al. Effects of treatment duration during concomitant chemoradiation therapy for cervical cancer. Int J Radiat Oncol Biol Phys. 2013; 86: 562-568 Abstract Full Text Full Text PDF PubMed Scopus (40) Google Scholar ) presents some useful data. Although not the primary focus of their manuscript, the plots of in-field relapse, disease-free survival (DFS), and overall survival (OS) are “alligator-shaped” (starting together at the snout, widening in the middle, then coming together again at the tail). The median follow-up in the two groups, that is, patients receiving radiation therapy (RT) alone versus those receiving concurrent chemoradiation therapy (CRT), is approximately 4 years. The number of patients at risk for in-field relapse was 55 versus 52, respectively, at 5 years and 21 versus 10, respectively, at 10 years, which are small numbers.
