Conditions studied: 3-year Disease-free Survival

In brief

To evaluate 3-year disease-free survival after complete resection in patients with MRD-positive EGFR-sensitive mutations in Stage IA2-IB NSCLC treated with adjuvant befortinib and under routine observation (3y-DFS).

Who can join

Age: 18 and older, up to 75. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Age: 18-75 years old.
• Gender: both men and women are acceptable, as balanced as possible.
• Patients with lung adenocarcinoma who underwent R0 resection and were clinically confirmed as IA2-IB by histopathology and whose tumor size was (1-4cm), the surgical tissue samples tested positive for EGFR-sensitive mutations and positive for MRD after surgery.
• Accompanied by arbitrary ≥ 2 high-risk factors; High risk factors such as pleural invasion, airway diffusion, vascular infiltration, low differentiation, pathological micropapillary composition ≥ 15%, complex glandular composition ≥ 20%, etc.
• Achieve R0 resection: For CTR < 50% ground glass nodules, wedge resection is acceptable and the margin is negative, and 3 groups of lymph node biopsies are negative; for CTR ≥ 50% or pure solid nodules, at least segmental resection is undergone, and lymph node dissection is systematically performed; if there is no clear evidence of metastasis, if it cannot be judged, it can be determined by an independent review committee for pathological consultation.
• The ECOG behavioral status score is 0 to 1, and the expected survival time is > 1 year.
• Voluntary MRD screening and voluntary befortinib adjuvant therapy; 7. Have a certain organ system function, defined as follows, based on the researcher's experience A. Absolute neutrophil count (ANC) ≥ 1.5 x 109/L B. Platelets ≥ 100 x 109/L; C. Hemoglobin ≥ 9 g/dL (≥ 90 g/L) Note that in order to achieve the required hemoglobin level, blood transfusion is allowed; D. Total bilirubin ≤ 1.5 times the upper limit of normal (ULN); E. If there is no liver metastasis, alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤ 2.5 × ULN; if liver metastasis, ≤ 5 × ULN; F. Creatinine ≤ 1.5 x ULN. Patients are still eligible for inclusion if the creatinine clearance value calculated by the Cockcroft-Gault method is ≥ 50 mL/min (0.83 mL/s).
• Female subjects of childbearing age must have a serum pregnancy test within 3 days before the start of the study drug, and the result is negative, and they are willing to use a medically approved high-efficacy contraceptive method (such as intrauterine devices, contraceptives or condoms) during the study period and within 3 months after the last administration of the study drug; for significant other male subjects who are women of childbearing age, they should be surgically sterilized, or agree to use effective methods of contraception during the study period and within 3 months after the last study dose.
• Voluntary and capable of following the test and follow-up procedures. 10. Sign the informed consent form.

You may not qualify if…

• There is any other treatment before the operation, and no informed consent is signed;
• The patient has been diagnosed with cancer within 2 years;
• Have a history of interstitial lung disease, drug-induced interstitial disease or any active interstitial lung disease with clinical evidence; CT scan at baseline revealed idiopathic pulmonary fibrosis.
• Patients who are known to be allergic to any component of befortinib or similar drugs;
• Pregnant or lactating women;
• Situations considered unsuitable for inclusion by other researchers.
