Individuals with advanced-stage anal squamous cell carcinoma with cancer spread only to the para-aortic lymph nodes who underwent extended-field radiotherapy and chemotherapy had a 67% overall survival rate, a 42% disease-free survival rate and no side effect-related mortality after 3.1 years, researchers reported in the International Journal of Radiation Oncology*Biology*Physics. Another study in the same journal involving patients with locally advanced anal cancer also showed higher odds of chemotherapy administration and completion among those who underwent intensity modulated radiation therapy, compared with those who received traditional radiation.
