Aim: To assess the clinical features/imaging characteristics of pneumonitis reported during nationwide nivolumab postmarketing surveillance in Japan. Patients & methods: Clinical and radiological data were collected from cases during/after treatment for melanoma or non-small-cell lung cancer. The expert central review committee evaluated each case. Results: Among 144 analyzed, 91 (63.2%) had patterns considered typical drug-induced 53 (36.8%) patients previously unobserved with one more...

To elucidate the roles ofSHP-2, we generated transgenic (Tg) mice expressing a dominant negative mutant lacking protein tyrosine phosphatase domain (ΔPTP). On examining two lines of Tg identified by Southern blot, transgene product was expressed in skeletal muscle, liver, and adipose tissues, insulin-induced association insulin receptor substrate 1 with endogenous SHP-2 inhibited, confirming that ΔPTP has property. The intraperitoneal glucose loading test demonstrated an increase blood...

Postmarketing surveillance of Japanese patients with unresectable, previously treated, advanced or recurrent non-small-cell lung cancer treated nivolumab was undertaken during the conditional approval period. The study aim to evaluate occurrence treatment-related adverse events in real world. Patients were registered between December 2015 and March 2016 at 536 sites. Nivolumab given intravenously (3 mg/kg every 2 weeks); observation period 12 months after first dose nivolumab. evaluated for...

Nivolumab, a monoclonal antibody against human programmed death 1, was approved for the treatment of melanoma in July 2014 Japan. Because Japanese phase II studies (ONO-4538-02, ONO-4538-08) enrolled small numbers patients, post-marketing surveillance (PMS; JapicCTI-163 272) conducted to collect safety data larger patient population. We report patients who received nivolumab between 4, and February 28, 2017. Data collected included baseline characteristics, laboratory tests,...

Abstract Nivolumab, a human monoclonal antibody against programmed death‐1, is approved for the treatment of non–small cell lung cancer (NSCLC). Although nivolumab generally well tolerated, it can cause interstitial disease (ILD), rare but potentially fatal immune‐related adverse event. Currently, there are limited data available on nivolumab‐induced ILD and its outcome. This retrospective cohort study based post–marketing described outcome in NSCLC patients Japan through assessment clinical...

Nivolumab can cause interstitial lung disease (ILD), which may be fatal; however, mortality risk factors have not been identified. This postmarketing study evaluated the poor prognostic of ILD in nivolumab-treated patients with non-small cell cancer (NSCLC) Japan. Clinical and chest imaging findings for each case were assessed by an expert central review committee, prognosis was radiographic findings, including presence/absence peritumoral ground-glass opacity (peritumoral-GGO). Poor...

Neutrophil-to-lymphocyte ratio (NLR) has recently attracted attention as a prognostic predictor in patients with non-small cell lung cancer (NSCLC) who receive immune checkpoint inhibitors (ICIs). However, the utility of NLR relation to cytotoxic anticancer drugs or molecular targeted remains unclear. We determined if could predict treatment efficacy and prognosis NSCLC drugs, well ICIs, cross-sectional manner.Of 658 advanced received first-line systemic our hospital between 2008 2019, 312...

In lung cancer, several potential mechanisms of intrinsic and acquired resistance to epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) have been explored, including mesenchymal-epithelial transition (MET) signaling pathway activation. On the other hand, vascular endothelial (VEGF) production EGFR-mutated cancer cells is stimulated by predominantly activated MET pathway. Therefore, inhibition VEGF axis as downstream target seems promising. Here, for first time, we...

It has been shown that metastases to the thyroid from extrathyroidal malignancies occur as solitary or multiple nodules, may involve whole gland diffusely. However, diffuse metastasis of gastric cancer is extremely rare. Here, we report a case 74-year-old woman with infiltration adenocarcinoma (signet-ring-cell carcinoma/poorly differentiated adenocarcinoma) cells in thyroid. The pathological diagnosis was made based on upper gastrointestinal endoscopy biopsy and fine-needle aspiration...

Common dermatological side-effects associated with erlotinib, epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI), include pruritus and skin rash, which are mediated by substance P, leading to the occasional discontinuation of cancer treatment. Aprepitant is an antagonist neurokinin-1 receptor, through P activates pruritogens. Thus, aprepitant expected offer a promising option for treatment erlotinib-induced pruritus. However, appropriate schedule administration under...
