The regimen of oxaliplatin with 5-fluorouracil plus l-leucovorin (FOLFOX) has become one of the most commonly used first-line chemotherapy for patients with advanced colorectal cancer and it provides an increase in disease-free survival as well as an overall survival benefit. Although FOLFOX chemotherapy has helped to improve the clinical outcomes in these patients, the regimen is associated with some therapeutic issues or uncontrolled side effects. Gastrointestinal, neurosensory, and hematological toxicities have frequently been observed in patients treated with FOLFOX, and consequently, some palliative treatment has been established to combat such complications. However, pulmonary toxicities including drug-induced interstitial pneumonia (DI-IP) is rarely observed in these patients and a curative treatment is yet to be established. DI-IP due to chemotherapy is most commonly observed in patients treated with mitomycin, paclitaxel, docetaxel, or gemcitabine. Steroid therapy is mostly used to treat DI-IP, although the efficacy of such treatments is not supported with adequate evidence. FOLFOX-induced interstitial pneumonia (FIIP) is rarely observed, and several case reports of FIIP treated with steroids have been published previously that showed the mortality is extremely high. Here, we present a 74-year-old woman who received modified FOLFOX6 as adjuvant chemotherapy after rectal cancer surgery. The patient experienced FIIP, which improved after application of steroid pulse (high-dose methylprednisolone at 1,000 mg/day for 3 days) and tapering (starting with prednisolone at 40 mg/day) therapy. Our data suggest that such a steroid therapy could represent an effective treatment option for FIIP.
