Publication date: Available online 10 January 2019Source: Respiratory Medicine Case ReportsAuthor(s): Hidenori Kawakami, Takao Miyabayashi, Chikako Tsubata, Kyuma Ota, Takashi Ishida, Osamu KobayashiAbstractWe retrospectively analyzed the data of 9 patients with organizing pneumonia induced by radiation therapy. Radiation therapy had been administered for breast cancer in 8 patients and for lung cancer in 1 patient. Symptoms were detected in 8 patients; however, none of the patients developed hypoxemia or respiratory failure, and the clinical course was good. Steroid therapy was administered to 3 patients; however, all 3 patients developed recurrence. In contrast, none of the 6 patients who received symptomatic treatment developed recurrence. Steroid treatment is often provided for patients with organizing pneumonia; however, the effect of steroid administration on recurrence rate needs to be examined. In addition, none of the patients died and only 1 patient with lung cancer required mechanical ventilation. Therefore, considering the serious side effects of steroid use, initial symptomatic treatment, and not steroid administration, may be best for patients. One exception would be for patients with hypoxemia or those whose symptoms adversely affect the activities of daily living. The incidence of radiation therapy-induced organizing pneumonia in lung cancer patients is higher and its severity is greater than that in breast cancer patients; however, the time to onset may be lo...
