Abstract: Objective To evaluate the influence of hyperthermia on T helper subgroup (T help type1/T help type2,Th1/Th2) for patients with esophageal carcinoma. Methods 22 patients of esophageal carcinoma were randomly divided into two groups. Both group patients were treated by external radiation, the total dose was 64-66 Gy/30-33 fractions. Radiotherapy was the only therapy method in group A. Hypertbermia was used twice every week, with 8-10 fractions except for radiotherapy in group B. All patients were phlebetomized at the beginning and the end of radiotherapy for examining Th1/Th2 by flow cytometry. Results Th1 was significantly decreased in group A(t = 5.33, P < 0.01). All indexes in group B had no difference (t = - 1.41, P > 0.05). TheThl in group A was decreased much more than that in group B(t = 4.28, P < 0.05). Conclusion Hyperthermia could rectify the balance of Th1/Tb2.
