Comparison between chemoselection and definitive radiotherapy in patients with cervical esophageal squamous cell carcinoma.

Abstract

BACKGROUD:

Laryngeal preservation is an important consideration when treating cervical esophageal cancers (CECs) such as laryngeal cancer. The standard treatment for CEC allowing laryngeal preservation is chemoradiotherapy. However, in cases of laryngeal cancer, chemoselection has also been applied as a treatment strategy that promotes larynx preservation. This strategy involves assigning the appropriate radical treatment according to the primary tumor's response to induction chemotherapy. Since there have been no studies of the application of chemoselection in CEC cases, the present study compared the results, including laryngeal preservation rates, obtained upon applying chemoselection and chemoradiotherapy to CEC.

STUDY DESIGN:

This was a retrospective cohort study of cervical esophageal squamous cell carcinoma patients treated using chemoselection or chemoradiotherapy at Aichi Cancer Center Hospital between January 2000 and March 2013. A total of 42 patients were enrolled.

RESULTS:

The 2-year overall survival and laryngeal preservation rates for the chemoselection group versus the primary radiotherapy group were 65.1 and 57.3 versus 40 and 83.3%, respectively (P = 0.017 and P = 0.122, respectively). The 2-year locoregional control rates for the chemoselection and primary radiotherapy groups were 68 and 25%, respectively (P = 0.045).

CONCLUSION:

The chemoselection group achieved favorable results. Therefore, chemoselection can be applied as a treatment strategy for CEC.
