NEW FOCUSES OUTSIDE RADIATION FIELDS OF ESOPHAGEAL CARCINOMA / 中华放射肿瘤学杂志

1128 esophageal carcinoma patients were treated by radiation therapy from Jaunary 1978 to December 1981. 64 cases with new focuses in superior and inferior margin of radiative field were 2.9% and 1.6% and in another region was 1.2%. 54 cases were retreated by radiation therapy. The 1-,2-,3- and 5 years survival rates were 53.7%,24.1%,13.5% and 5.8%. We think that new focus outside radiative fields was great different from local recurrence and uncontral cancers. Those patients can still be treated by radical radiation therapy. It is reasonable to prolong 3cm in length above and below the lesion for initial radiotherapy.
