METHODS Forty patients were included in this study. Pretreatment and 3 months after completion of radiotherapy (RT), values of forced vital capacity (FVC), forced expiratory volume in first second (FEV1), and FEV1/ FVC ratio were measured and recorded. RESULTS Restrictive pattern was seen in 4 patients in baseline PFTs and moderate deterioration was observed in their measurements of PFT at 3 months after RT. Obstructive pattern was defined in only 1 patient in baseline PFTs and it remained unchanged after RT. Mild obstructive pattern in 4 patients and mild restrictive pattern in 3 patients had developed at 3 months after RT. CONCLUSION Minimal changes that result in mild restrictive and obstructive pattern in PFTs can be seen in acute phase after RT with HT.eninfo:eu-repo/semantics/openAccessBreast cancerRadiation pneumonitisTomotherapyEvaluation of pulmonary function after radiotherapy using helical tomotherapy for breast cancer treatment: Prospective studyEvaluation of pulmonary function after radiotherapy using helical tomotherapy for breast cancer treatment: Prospective studyArticle3138996WOS:0003933188000032-s2.0-8500757563824062510.5505/tjo.2016.1401Q4N/A
