Radiation alone may suffice for some nasopharyngeal cancer
Source: www.medpagetoday.com Author: Ed Susman, Contributing Writer, MedPage Today In selected patients with nasopharyngeal carcinoma, radiation alone may do as much against the disease as the combination of radiation and chemotherapy but with fewer adverse effects, researchers suggested here. About 90% of patients who received radiation alone achieved failure-free survival at 3 years versus 91.9% of patients treated with both radiation and chemotherapy (P=0.86; non-inferiority P<0.001), reported Jun Ma, MD, PhD, of Sun Yat-sen University Cancer Center in Guangzhou, China. In his virtual oral presentation at the annual meeting of the American Society of Clinical Oncology, Ma also reported that 98.2% of patients treated with radiation alone survived to 3 years compared with 98.6% of patients who got both radiation and chemotherapy (P=0.30). The multifaceted subgroup analysis almost entirely favored treatment with alone. There was no difference in distant metastasis-free survival (95% in both arms) or local-regional recurrence-free survival, with both arms hovering in the 90-92% level. And patients treated with both therapeutic modes paid a price in adverse events (AEs), Ma reported, noting that grade 3 to 4 mucositis was observed in 18.9% of patients on chemoradiation but in just 9.7% of those on radiation therapy alone. A similar story in AEs was observed for leukopenia, neutropenia, nausea (0.6% vs 13% grade 3-4), vomiting (1.2% vs 14.8%), anorexia (4.8% vs 29%), and weight loss. That differential in AEs was reflected in quality of life measurements, with better scores in the radiation-only group as far as their global health status, [...]
