Abstract:
Background: Radiotherapy plays an important role in the treatment of breast cancer. In the process of radiotherapy, the underling lung tissue receives higher doses from treatment field, which led to incidence of radiation pneumonitis. Objective: The present study aims to evaluate the predictive factors of radiation pneumonitis and related changes in pulmonary function after ۳D-conformal radiotherapy of breast cancer.Material and Methods: In prospective basis study, thirty-two patients with breast cancer who received radiotherapy after surgery, were followed up to ۶ months. Respiratory symptoms, lung radiologic changes and pulmonary function were evaluated. Radiation pneumonitis (RP) was graded according to common terminology criteria for adverse events (CTCAE) version ۳.۰. Dose-volume parameters, which included percentage of lung volume receiving dose of d Gy (V۵-V۵۰) and mean lung dose (MLD), were evaluated for RP prediction. Pulmonary function evaluated by spirometry test and changes of FEV۱ and FVC parameters. Results: Eight patients developed RP. Among the dose-volume parameters, V۱۰ was associated to RP incidence. When V۱۰<۴۰% and V۱۰≥۴۰% the incidences of RP were ۵.۲۶% and ۶۱.۵۴%, respectively. The FEV۱ and FVC had a reduction ۳ and ۶ months after radiotherapy, while only FEV۱ showed significant reduction. The FEV۱ had more reduction in the patients who developed RP than patients without RP (۱۵.۲۵±۳.۸۱ vs. ۹.۲±۰.۹۳). Conclusion: Pulmonary function parameters, especially FEV۱, significantly decreased at ۳ and ۶ months after radiotherapy. Since most patients with breast cancer who developed RP did not show obvious clinical symptoms, so spirometry test is beneficial to identify patients with risk of radiation pneumonitis.
