Larynx Preservation Rate in Laryngeal Cancer Patients Treated with Chemotherapy and Radiotherapy: An Institutional Review of 250 Patients
Introduction: Chemo-radiation preceded by induction chemotherapy is reported valuable alternative to laryngectomy in laryngeal cancer for larynx preservation.This study was performed to assess the influence chemo radiation on preservation of larynx.
Materials and Methods: Two hundred and fifty sequential patients treated from January 2012 to December 2012 in our institute were reviewed and who were available for follow-up in this retrospective study. Total dose of 66-70 Gray was used at 2 gray per fraction daily for five days week were used. Larynx preservation rate at3 years of median follow-up were analyzed.
Results: Among 250 patients, larynx preservation was possible in 170 patients (68%). With chemo-radiation, excellent preservation of larynx was achieved in stage II (78%) disease, while in advanced stage III and stage IVA, larynx preservation was67.06% and 64.35%, respectively.
Conclusion: Chemo-radiation (either neoadjuvant chemotherapy followed by chemoradiation or concurrent chemo-radiation) has better larynx preservation rate in early as well was advanced laryngeal cancer patients.
