The efficacy of stereotactic body radiation therapy (SBRT) for patients treated with domiciliary oxygen therapy is not well-known.
We collected the clinical records of 15 patients with chronic respiratory insufficiency requiring domiciliary oxygen therapy at 1-3 l/min who were treated with SBRT for stage I non-small cell lung cancer. All patients were fixed with a thermoplastic body cast system. SBRT was given in 7-8 fields with an isocenter dose of 40-60 Gy in 4-10 fractions (median, 48 Gy in 4 fractions).
The overall 2-year and 5-year survival rates for all patients were 67.4% and 34.7%, while the disease-specific 2-year and 5-year survival rates were 90.0% and 72.0%, respectively. Pulmonary adverse effects were mild in the majority of the patients, although two patients had grade 2 radiation pneumonitis. The oxygen flow required increased slightly at follow-up periods greater than one year, but was still at an acceptable level.
SBRT was feasible for patients requiring domiciliary oxygen therapy.
接受家庭氧疗的患者行立体定向体部放射治疗(SBRT)的疗效尚不清楚。
我们收集了 15 例患有慢性呼吸功能不全、需要 1-3L/min 家庭氧疗的患者的临床记录,这些患者因Ⅰ期非小细胞肺癌接受 SBRT 治疗。所有患者均采用热塑体模系统固定。SBRT 采用 7-8 野照射,等中心剂量为 40-60Gy,分 4-10 次(中位数:4 次,48Gy)。
所有患者的总 2 年和 5 年生存率分别为 67.4%和 34.7%,疾病特异性 2 年和 5 年生存率分别为 90.0%和 72.0%。大多数患者的肺部不良反应较轻,但有 2 例患者出现 2 级放射性肺炎。在随访 1 年以上的时间里,氧气流量略有增加,但仍处于可接受的水平。
SBRT 对于需要家庭氧疗的患者是可行的。
