Adjuvant osimertinib therapy guided by ctDNA-assessed MRD in resected EGFR-mutated stage IA-IIA non-small-cell lung cancer: a randomized clinical trial study protocol.

Aims: We investigate the value of postoperative minimal residual disease (MRD) detection using circulating tumor DNA (ctDNA) in guiding adjuvant therapy for patients with potentially high recurrence risk in non-small cell lung cancer (NSCLC) due to the presence of MRD.

Patients And Methods: A randomized controlled trial will enroll stage IA-IIA NSCLC patients with Epidermal Growth Factor Receptor (EGFR) mutation and negative resection margins to evaluate the clinical value of MRD in guiding adjuvant osimertinib. That is, if the patient's peripheral blood does not show ctDNA (negative) after next generation sequencing (NGS) testing, postoperative observation and follow-up are sufficient.

Highly efficient Ni/Ac-AlO catalysts in the dry reforming of methane: influence of acetic acid treatment and Ni loading.

The presence of abundant hydroxyl groups on the surface of AlO can promote the dispersion of Ni species but produce an inactive NiAlO phase at high temperatures. Moreover, the catalysts prepared by the conventional incipient wetness impregnation method lack the sites for the activation of CO, which leads to coke deposition and thus affects the catalyst activity. The above restricts the utilization of Ni in conventional Ni/AlO catalysts.
