The particular anatomic distribution and peripheral enhancement patterns of contrast-enhanced MRI with quantitative analysis might be useful in the diagnosis of abdominal tuberculous lymphadenopathy.

Our findings indicate that a specific enhancement pattern of lymphadenopathy seen on MDCT was useful in differentiating between untreated TB and lymphomas of the cervical lymph nodes.

The distribution and enhancement pattern of enlarged lymph nodes on MDCT was useful in differentiating TB and CLL.

Background: As a third generation epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI), osimertinib is recommended as standardized treatment for advanced or metastatic non-small cell lung cancer (NSCLC) patients with EGFR-T790M mutation after progressed on first-line EGFR-TKI. Our study aims to investigate the prognostic value of first-line EGFR-TKI on the second-line osimertinib in the real-world practice.Methods: A total of 198 NSCLC patients with EGFR-T790M between 2016 and 2020 were included in this study. All patients were resistant to first-line EGFR-TKI and received osimertinib as second-line therapy. The endpoint was the occurrence of progression on osimertinib. Univariate and multivariate COX regression analysis were used to identify the prognostic value of clinical factors. Log-rank test was conducted to compare survival outcomes of different groups.
