Purpose Although corticosteroids can relieve dyspnea in advanced cancer patients, factors predicting the response remain unknown. We aimed to explore potential factors predicting the response to corticosteroids for dyspnea in advanced cancer patients. Methods In this preliminary multicenter prospective observational study, we included patients who had metastatic or locally advanced cancer, were receiving specialized palliative care services, and had a dyspnea intensity of ≥3 on a 0–10 Numerical Rating Scale (NRS) (worst during the last 24 h). The primary endpoint was NRS of dyspnea on day 3 after the administration of corticosteroids. Univariate/multivariate analyses were conducted to identify factors predicting ≥1-point reduction in NRS. Results Of 74 patients who received corticosteroids, 50 (68%) showed ≥1-point reduction in dyspnea NRS. Factors that significantly predicted the response were an age of 70 years or older (82 vs. 53%, p  = 0.008), absence of liver metastases (77 vs. 46%, p  = 0.001), Palliative Prognostic Index (PPI) ≤ 6 (90 vs. 61%, p  = 0.041), presence of pleuritis carcinomatosa with a small collection of pleural effusions (84 vs. 55%, p  = 0.011), presence of audible wheezes (94 vs. 60%, p  = 0.014), and baseline dyspnea NRS ≥7 (76% vs. 52%, p  = 0.041). In a multivariate analysis, factors predicting response included PPI
