Advanced anaplastic lymphoma kinase (ALK) fusion-positive non–small-cell lung cancers (NSCLCs) are effectively treated with ALK tyrosine kinase inhibitors (TKIs). However, clinical outcomes in these patients vary, and the benefit of TKIs is limited as a result of acquired resistance. Emerging data suggest that the ALK fusion variant may affect clinical outcome, but the molecular basis […]

We previously reported durable responses and manageable safety of ibrutinib from a 3-year follow-up of treatment-naive (TN) older patients (≥65 years) and relapsed/refractory (R/R) patients with chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL). We now report on long-term efficacy and safety with median follow-up of 5 years in this patient population with TN (N=31) and R/R

This is the first decision impact study to include exclusively women with ER-positive, HER2-negative, early-stage breast cancer with 1-3 positive lymph nodes, a population typically treated with adjuvant chemotherapy. This study provides evidence that, in these patients, the Oncotype Dx Recurrence Score assay influences systemic treatment decisions. Most of the changes in treatment recommendation resulted

The median progression-free survival was significantly longer with osimertinib than with standard EGFR-TKIs (18.9 months vs. 10.2 months; hazard ratio for disease progression or death, 0.46; 95% confidence interval [CI], 0.37 to 0.57; P<0.001). The objective response rate was similar in the two groups: 80% with osimertinib and 76% with standard EGFR-TKIs (odds ratio, 1.27;

The androgen receptor (AR) is increasingly recognized as a potential biomarker for identifying a subset of patients with possible hormonally driven triple-negative breast cancer (TNBC). However, its performance as a companion diagnostic remains elusive. Thus, we evaluated AR expression by immunohistochemistry in patients with advanced TNBC before treatment with the AR inhibitor enzalutamide. We optimized

RAS mutation status is an important prognostic factor after resection of liver metastases (LiM) from colorectal cancer (CRC). The prognostic significance of RAS after resection of lung (LuM) and peritoneal (PM) metastases from CRC is unknown. A total of 720 patients with known RAS status underwent resection of LiM (n = 468), LuM (n = 102), and PM (n = 150). RAS

Among patients who undergo the 21-gene assay (21-GA), 39% to 67% receive an intermediate risk result and may receive ambiguous treatment guidance. The 70-gene signature assay (70-GS) may be associated with physicians’ treatment decisions in this population with early breast cancer. Among the 840 patients who underwent 70-GS classification (mean age, 59 years; range, 27-93 years),

The present meta-analysis revealed that cases of breast cancer with PD-L1 positivity in all cells exhibited higher histological grades, lymph node metastasis, and poorer disease-free survival. Therefore, positive expression of PD-L1 may be a useful prognostic marker in breast cancer. Six studies that included 7877 cases were selected for the analysis. Higher PD-L1 expression in all

This study looked at survival and MLH1 expression in patients with pancreatic cancer who had undergone resection and received adjuvant chemoradiation. Two different adjuvant protocols were compared. Samples from 117 patients from the two arms were stained. Overall, 84% of these patients had died by the time of this analysis (median of 17 months’ survival).

Early detection and intervention are likely to be the most effective means for reducing morbidity and mortality of human cancer. However, development of methods for noninvasive detection of early-stage tumors has remained a challenge. We have developed an approach called targeted error correction sequencing (TEC-Seq) that allows ultrasensitive direct evaluation of sequence changes in circulating
