Non-Small Cell Lung Cancer, Rare Mutation of HER2, Pyrotinib
Brief summary
At present, the main characteristics of the enrolled population in the clinical study of HER2-mutated non-small cell lung cancer are the YVMA mutation type. There are no relevant clinical trials specifically targeting rare mutation types. Pyrotinib has been approved for the treatment of HER2-positive advanced breast cancer in China, and pyrotinib has shown good development prospects in the treatment of advanced non-small cell lung cancer. The purpose of this study is to observe the efficacy and safety of pyrotinib maleate in patients with HER2 rare mutation in advanced non-small cell lung cancer.
Interventions
Pyrotinib maleate tablets 400 mg/day, oral within 30 minutes after breakfast, every 4 weeks is a cycle

Inclusion criteria
* 1\. Age: 18-70 years old; * 2\. Advanced/metastatic non-small lung cancer (IV) confirmed by pathology with measurable lesions; * 3\. HER2 mutation and amplification confirmed by gene testing of tumor tissue or blood, pleural effusion, cerebrospinal fluid and other specimens; * 4\. ECOG：0-1; * 5\. At least one radiographically measurable lesion * 6\. Expected survival period ≥ 3 months * 7\. Left ventricular ejection fraction (LVEF) ≥ 50% on echocardiography * 8\. Before using the drug for the first time, it was confirmed by laboratory tests that the subject's bone marrow function, liver and kidney function met the following requirements： 1. Neutrophil count (ANC) ≥ 1,500/mm3 (1.5×109/L); 2. Platelet count (PLT) ≥ 100,000/mm3 (100×109/L); 3. Hemoglobin (Hb) ≥ 8 g/dL (80 g/L); 4. Serum creatinine (SCr) ≤ 1.5 times the upper limit of normal (ULN) or creatinine clearance ≥ 60 ml/min; 5. Total bilirubin (TBIL) ≤ 1.5 times the upper limit of normal (ULN); 6. Aspartate aminotransferase (AST) or alanine aminotransferase (ALT) levels ≤ 2.5 times the upper limit of normal (ULN), and subjects with liver metastases should be ≤ 5×ULN; 7. International normalized ratio (INR) ≤ 1.5, prothrombin time (PT) and activated partial thromboplastin time (APTT) ≤ 1.5 times ULN; 8. Urine protein \<2+; if urine protein ≥2+, the 24-hour urine protein quantification shows that protein must be ≤1g; * 9\. The medication regimen of the subjects during the clinical diagnosis and treatment was pyrotinib as a single drug * 10\. Patients voluntarily entered the study and signed informed consent form (ICF)
