We tried to evaluate whether there are any specific features in treatment outcomes of firstline afatinib in patients with epidermal growth factor receptor (EGFR)-mutant non-small cell lung cancer (NSCLC), compared with gefitinib or erlotinib. ⋯ First-line afatinib showed satisfactory efficacy data and manageable toxicity profiles.

Administering the best treatment after failure of epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI) therapy requires knowledge of resistance status. In this trial, treatment efficacy of osimertinib was assessed in patients with non-small cell lung carcinoma (NSCLC) harboring the T790M resistance mutation, detected from circulating tumor DNA (ctDNA) with unknown tumor mutation status. ⋯ Osimertinib has favorable efficacy in patients with NSCLC harboring T790M, detected from ctDNA with unknown tumor mutation status, in whom disease had progressed during prior EGFR-TKI therapy.

Multicenter Study Observational Study
Treatment Patterns and Changes in Quality of Life during First-Line Palliative Chemotherapy in Korean Patients with Advanced Gastric Cancer.
The purpose of this study was to evaluate chemotherapy patterns and changes in quality of life (QOL) during first-line palliative chemotherapy for Korean patients with unresectable or metastatic/recurrent gastric cancer (GC). ⋯ This observational study provides important information on the chemotherapy patterns and QOL changes in Korean patientswith advanced GC. Overall, first-line palliative chemotherapy was found to maintain QOL, and most parameters showed an improvement compared with the baseline at some point during the course.

The intermediate stage of hepatocellular carcinoma (HCC) (Barcelona Clinic Liver Cancer [BCLC] B) comprises a highly heterogeneous population, and the treatment strategy is still controversial. Because of the heterogeneity, a subclassification of intermediate-stage HCCs was put forward by Bolondi according to the 'beyond Milan and within up-to-7' criteria and Child-Pugh score. In this study, we aim to analyze the prognosis of BCLC-B stage HCC patients who received hepatic resection according to the Bolondi's subclassification. ⋯ In our study, HCC patients at B1 stagewere benefited from hepatic resection and had similar survival to BCLC-A stage patients. Our study provided rationality of hepatic resection for selected BCLC-B stage HCC patients instead of routine transarterial chemoembolization.

Multicenter Study Comparative Study
Breast Conservation Therapy Versus Mastectomy in Patients with T1-2N1 Triple-Negative Breast Cancer: Pooled Analysis of KROG 14-18 and 14-23.
The aim of this study is to compare the treatment outcomes of breast conserving surgery (BCS) plus radiotherapy (RT) versus mastectomy for patients with pT1-2N1 triple-negative breast cancer (TNBC). ⋯ In pT1-2N1 TNBC, breast conservation therapy achieved better locoregional recurrencefree, disease-free, and overall survival rates compared with mastectomy.
