Chemoradiotherapy May Benefit Recurrent Head, Neck Cancers
THURSDAY, June 16 (HealthDay News) -- Retreatment with concurrent chemotherapy and reirradiation (CReRT) may be a treatment option for a specific group of patients with recurrent or second primary head and neck cancer (HNC), although prior treatment with chemoradiotherapy (CRT) is associated with worse overall survival (OS), according to a study published online June 13 in Cancer.
