ABSTRACT
Objective To study the set-up accuracy in radiotherapy of thoracic neoplasms by improving the body immobilization method.Methods Fifty patients with thoracic neoplasms were randomly divided into conventional group (without electrode paste) and improved group (with electrode paste).Using simulator for position calibration and center field digital image reconstruction from treatment planning system.Then compare the set-up accuracy of two groups with different body methods by grouped t-test.Results Set-up error in the left-right,superior-inferior,anterior-posterior direction were 2.5 ± 1.5 and 2.4 ± 1.4(P =0.010),4.4 ± 2.0 and 2.2 ± 1.2 (P =0.000),2.2 ± 1.3 and 2.1 ± 1.0 (P =0.100) in conventional group and improved group,respectively.Conclusions The improved body immobilization method improves setup accuracy in radiotherapy for thoracic neoplasms which also will be effective for clinical treatment.
ABSTRACT
[Objective] To explore effective method for later skin scale cancer. [Method] Apply radio-chemical therapy combined Shun Platinum to 23 cases of said disease, observe clinical effect and toxic and side effects. [Result] 5 cases were completely relieved, 16 partly relieved, 2 stable, the total effective rate 91.3%; toxic and side effects: 4 cases reduced white cells, 13 acute skin reaction. [Conclusion] For the local later skin scale cancer, esp. the cancer ulceration in the skin surface, to take low-density Shun Platinum combined with radio-chemical therapy can improve local treatment, meanwhile without increasing toxic or side effects.
