    Abstract: e15171 Background: Immune check point inhibitor (ICI) induced interstitial lung disease (ICI-ILD) is a clinically serious and life-threatening toxicity. Pre-existing ILD has been reported to be a risk factor for ICI-ILD in patients with non-small cell lung cancer (NSCLC). In addition, we have previously reported that interstitial lung abnormality (ILA) is also a risk factor for the ICI-ILD. Therefore, we investigated whether any patient characteristics, including ILA, were risk factors for ICI-ILD in patients with non-NSCLC cancers. Methods: Head and neck cancer, malignant melanoma, oral cavity cancer, renal cell carcinoma or gastric cancer patients who received anti PD-1 antibody (Nivolumab or Pembrolizumab) at Hiroshima University Hospital from December 2015 to May 2019 were enrolled. Information on patient characteristics before anti-PD-1 antibody administration, including chest CT findings and laboratory data, were obtained. Results: Two hundred patients were enrolled, and 20 (10%) developed ICI-ILD. Grade1 was observed in 15 patients, grade2 in 3, and grade3 and 5 in 1. There was no significant difference in the background factors between patients with and without ICI-ILD. On the other hand, the proportion of patients with ILA was significantly higher in the patients with ICI-ILD than those without (P 〈 0.01). Furthermore, univariate logistic regression analysis revealed ILA was the risk factor for ICI-ILD (p 〈 0.01), and multivariate logistic regression analysis showed that GGA or reticulation in ILA was an independent risk factor for ICI-ILD (p = 0.016, 0.011). Conclusions: Pre-existing ILA is a risk factor for ICI-ILD, and GGA or reticulation in ILA is an independent risk factor for ICI-ILD in patients with non-NSCLC cancers. Therefore, we should pay more attention to the development of ICI-ILD in patients with ILA, especially GGA or reticulation.

    Clinical significance of BIM-deletion polymorphism on chemoradiotherapy in patients with non-small cell lung cancer.
    American Society of Clinical Oncology (ASCO) ; 2020

    Abstract: e21536 Background: The standard treatment for locally advanced non-small cell lung cancer (NSCLC) is chemoradiotherapy (CRT) followed by anti-programmed cell death-ligand 1 (PD-L1) drug therapy. BIM deletion induces apoptosis suppression and the effect of epidermal growth factor-tyrosine kinase inhibitor is reportedly attenuated in EGFR-mutated NSCLC patients with BIM deletion. This study retrospectively examined the effects of BIM deletion on CRT or PD-1 treatment in patients with NSCLC. Methods: Among patients with unresectable NSCLC at Higashi-Hiroshima Medical Center and Hiroshima University Hospital between April 1994 and April 2018, we enrolled those treated with CRT or chemotherapy using carboplatin + paclitaxel or cisplatin + vinorelbine, or PD-1 antibody treatment. Results: Of 1,224 patients with unresectable NSCLC, 88, 80, and 79 underwent CRT, chemotherapy, or PD-1 antibody treatments, respectively. Within these treatment groups, 15 (17%), 15 (19%) and 11 (14%) patients, respectively, had BIM deletion. Among patients receiving CRT, the progression-free survival and overall survival were significantly shorter in those with BIM deletion than in those without (150 vs. 254 days, p = 0.003; 429 vs. 710 days, p = 0.03). Moreover, multivariate Cox regression analysis showed BIM deletion to be an independent factor for anti-tumor effect or prognosis (hazard ratio [95% confidence interval] 2.042, [1.112–4.039], p = 0.029; 2.414, [1.063–4.984] , p = 0.036). These results were not observed in the chemotherapy and PD-1 treatment groups. To confirm the association between radiation therapy effect and BIM deletion, we performed in vitro experiments using two NSCLC cell lines (A549 and EBC-1). Suppressed BIM expression using siRNA (instead of BIM deletion) in these cells showed significantly suppressed antitumor effect and apoptosis 48 hours after 30-Gy irradiation but not chemotherapy. Conclusions: We showed that BIM deletion is an independent anti-tumor effect or prognostic factor for CRT. The results also indicated that BIM deletion was associated with the effects of radiation but not chemotherapy or PD-1 antibody treatment.

    EGFR gene mutation is not a significant prognostic factor in patients with EGFR mutated non-small cell lung cancer who receive best supportive care alone.
    American Society of Clinical Oncology (ASCO) ; 2020

    Abstract: e21736 Background: Epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs), are less toxic than conventional chemotherapy drugs, and benefit patients with EGFR-mutated non-small cell lung (NSCLC) cancer. However, there are a few patients who are not able to receive EGFR-TKI due to poor performance status, older age, or sever comorbidities. Here, we aimed to determine the prognostic significance of EGFR mutation in NSCLC patients who received best supportive care (BSC) alone, and compare the anti-tumor outcomes of only EGFR-TKI-treated patients vs. BSC patients. Methods: We retrospectively reviewed the medical records of patients diagnosed with NSCLC at Higashihiroshima Medical Center during April 1991–January 2019 and Hiroshima University Hospital during April 2008–August 2018. Results: A total of 1163 patients diagnosed with unresectable NSCLC were included in this analysis. Of these 1163 patients, 234 patients received BSC alone.Among 196 patients who underwent EGFR mutation analysis, 38 and 158 did and did not harbor an EGFR mutation, respectively, and the mean survival times (MST) did not differ significantly between these groups (121 vs. 85 days, p = 0.789). Consistent with the survival analysis, the multivariate Cox regression analyses showed EGFR mutation was not an independent prognostic factor. After propensity score matching, a comparison of only EGFR-TKI-treated (n = 35) and BSC patients (n = 35) with EGFR mutation revealed that the former had a significantly longer MST than the latter (372 vs. 121, p 〈 0.001). Conclusions: EGFR mutation itself was not a significant prognostic factor in untreated NSCLC patients. The patients who received EGFR-TKI had a significantly longer MST than their untreated counterparts. Our results may help to explain the benefit of EGFR-TKI, particularly for patients who would be directed towards treatment with BSC.
