Abstract
Objective To study the designing of treatment plan for huge primary liver cancer treated by γ-ray stereotactic radiotherapy. Methods 37 patients with huge primary liver cancer were treated with γ-ray stereotatic radiotherapy (SRT). Each planning target volume was more than 300 cm3 (vptv≥300cm3). The dose of 3200~3900cGy were delivered to PTVs with the fraction dose of 300~350cGy and 6 consecutive fractions per week. The planning targets were all surrounded by 50%~55% isodose curve. 14~22 isocenters were needed in each treatment plan in order to cover the PTV by 50%~55% isodose curve. The index of dose homogeneity of target was 1.60~1.72. There was no normal tissue that couldn't tolerate the irradiation involved. Results All patients were examined with image of CT or MRI. The total effective rate (CR+PR),steady disease(SD),progressive disease (PD)was 78.4%,8.1% and 13.5%,respectively. The main gastrointestinal complications were uncomfortable upper abdomen and poor appetite. Conclusions Qualified treatment plan for huge primary liver cancer treated by γ-ray stereotactic radiotherapy could be designed,but lots of isocenters were needed in the treatment plan and the dose in the target was not homogeneous.关键词
