Abstract

Abstract: Identify a subset of early-stage HL children (GR1) curable with limited chemotherapy+/-radiotherapy; improve outcome of intermediate (GR2) and high-risk (GR3) patients; establish impact of response to chemotherapy evaluated with conventional imaging (CI). One hundred and sixty GR1-patients received 3ABVD + involved-field (IF) low-dose (LD) (20 Gy) irradiation if mediastinal mass or partial response (PR) after chemotherapy. Eighty-five GR2- and 315 GR3-patients received 4 and 6 COPP/ABV + IFRT, respectively. The 63 GR1 patients spared from radiotherapy had 15-year survival and EFS of 100 and 84.5%, respectively. The GR2 and GR3 15-year FFP were 84.7 and 78.6%, respectively. No different prognosis for patients in CR or PR evaluated during and after chemotherapy was observed. In conclusion, low-risk patients in CR may be successfully treated with radiation-free, low-intensity chemotherapy. Good, but less satisfactory, results were registered in GR2 and GR3. Response evaluated with CI is not a prognostic factor, but permits identification of low-risk patients who can avoid radiotherapy.
