A 63-year-old man with occupational exposure to silica presented with cutaneous ulcer, pleuritic pain, and a fever. Laboratory data showed lymphopenia and positive serum antinuclear and anti-DNA antibodies. Computed tomography of the chest showed egg shell-like calcification of the hilar and mediastinal lymph nodes without pulmonary parenchymal involvement of silicosis. A surgical biopsy showed silicotic nodules with surrounding infiltration of lymphocytes and plasma cells in the parietal pleura. With a diagnosis of systemic lupus erythematosus (SLE), systemic corticosteroid therapy was given, which led to the resolution of symptoms and laboratory abnormalities. We discuss the relationship between silica exposure and the development of SLE.

Pre-existing interstitial lung disease (pre-ILD) increases the risk of chemotherapy-related lung injury (CRLI). However, whether the risk varies by type of anti-cancer cytotoxic agent in patients with pre-ILD is unknown. In this study, we hypothesized that S-1, an oral fluoropyrimidine agent, is associated with a smaller CRLI risk than docetaxel (DTX) and investigated these agents together with radiological evaluations of pre-ILD via pre-treatment chest computed tomography (CT). After reviewing 234 and 352 patients who underwent evaluable chest CT within 6 months prior to the administration of S-1 or DTX, respectively, from January 2006 to October 2014, 60 and 89, respectively, of these patients with pre-ILD were retrospectively analysed. In total, 2 persons administered S-1 (3 %) and 16 treated with DTX (18 %) developed CRLI (p = 0.007) after the initial treatment (mean, 61 days), of whom 1 and 7, respectively, died because of respiratory failure. Pre-treatment CT revealed that 9 S-1-treated patients (16 %) and 15 DTX-treated patients (17 %) had pre-ILD occupying more than 25 % of the lung field. Multivariate analysis demonstrated that DTX administration increased the risk of CRLI by 6.47-fold versus S-1 therapy (p = 0.016). Of note, the area occupied by pre-ILD was also associated with the risk of CRLI (

Background/aim The aim of this study was to reveal risk factors for lung injury following irinotecan administration for the treatment of neoplasms. Patients and methods This study included 204 patients who received irinotecan from October 2005 to November 2014 and had evaluable chest CT images before initiation of irinotecan. Results Six (2.9%) patients developed lung injury and, of these, 2 had preexisting interstitial lung disease (pre-ILD). The frequency of lung injury in patients with pre-ILD was 11% (2 of 19) while that in patients without pre-ILD was 2.2%. Risk factor analysis for the lung injury showed pre-ILD was the most predictable factor [odds ratio (OR) 5.00, p=0.07]. Combination with other agents, origin of neoplasms (lung or not), initial dose or minimum interval were not observed to be related to risk. Conclusion The risk of lung injury with irinotecan was high when pre-ILD was present and the risk was comparable with previously reported other agents.

Background The management of skin toxicity is crucial for efficient afatinib treatment, but the role of tetracycline class antibiotics (TCs) in managing these rashes is relatively unknown. Methods We reviewed the clinical records of patients who were administered afatinib for the treatment of non-small cell lung cancer harboring epidermal growth factor receptor mutations between October 2014 and November 2016. Twenty-five patients, who received TCs for the management of afatinib-related skin disorders, were enrolled. Results Minocycline was administered orally to participants. Afatinib-related toxic effects, such as rash, diarrhea, and paronychia, were observed in 92%, 92%, and 40% of cases, respectively. Although 24% of diarrhea and 4% of paronychia cases were rated grade 3 or higher, no severe cases of rash were observed during afatinib treatment. Of the 18 afatinib dose reductions, 14 (78%), three (17%), and one (6%) resulted from diarrhea, paronychia, and stomatitis, respectively; no patients required a dose reduction because of rash. When minocycline treatment started, 21 patients (84%) had a rash of grade 1 or less, and three patients had a grade 2 rash. A response to afatinib was observed in 18 patients (72%) and the median duration of afatinib administration was 501 days. An adverse event related to minocycline (grade 1 nausea) was observed in one patient. Conclusions A large proportion of the study patients started minocycline before grade 2 rash development and the severity of afatinib-related rash was lower than that previously reported. Oral TCs may be beneficial, especially if started early.
