PD-1 checkpoint inhibition has revolutionized the care of cancer. A small portion of patients with stage IV cancer achieve durable control. But, early progression is common and dramatic control is achieved for only a minority.

View Article and Find Full Text PDFBackground: Tumor samples from the phase III IMpower010 study were used to compare two programmed death-ligand 1 (PD-L1) immunohistochemistry assays (VENTANA SP263 and Dako 22C3) for identification of PD-L1 patient subgroups (negative, positive, low, and high expression) and their predictive value for adjuvant atezolizumab compared with best supportive care (BSC) in resectable early-stage non-small cell lung cancer (NSCLC).
Methods: PD-L1 expression was assessed by the SP263 assay, which measured the percentage of tumor cells with any membranous PD-L1 staining, and the 22C3 assay, which scored the percentage of viable tumor cells showing partial or complete membranous PD-L1 staining.
Results: When examining the concordance at the PD-L1-positive threshold (SP263: tumor cell (TC)≥1%; 22C3: tumor proportion score (TPS)≥1%), the results were concordant between assays for 83% of the samples.
Purpose: Patients with advanced pancreatic cancer have a poor prognosis and there have been no improvements in survival since the introduction of gemcitabine in 1996. Pancreatic tumors often overexpress human epidermal growth factor receptor type 1 (HER1/EGFR) and this is associated with a worse prognosis. We studied the effects of adding the HER1/EGFR-targeted agent erlotinib to gemcitabine in patients with unresectable, locally advanced, or metastatic pancreatic cancer.

Methods: The open-label, phase 1/2 ECHO-203 study evaluated the safety, tolerability, and efficacy of the IDO1 inhibitor epacadostat in combination with durvalumab, a human anti-PD-L1 monoclonal antibody in adult patients with advanced solid tumors.
Results: The most common treatment-related adverse events were fatigue (30.
Purpose: To assess whether reirradiation (re-RT) and concurrent bevacizumab (BEV) improve overall survival (OS) and/or progression-free survival (PFS), compared with BEV alone in recurrent glioblastoma (GBM). The primary objective was OS, and secondary objectives included PFS, response rate, and treatment adverse events (AEs) including delayed CNS toxicities.
Methods: NRG Oncology/RTOG1205 is a prospective, phase II, randomized trial of re-RT and BEV versus BEV alone.
Background: The NSABP B-36 compared four cycles of doxorubicin and cyclophosphamide (AC) with six cycles of 5-fluorouracil, epirubicin, and cyclophosphamide (FEC-100) in node-negative early-stage breast cancer. A sub-study within B-36, focusing on symptoms, quality of life (QOL), menstrual history (MH), and cardiac function (CF) was conducted.
Patients And Methods: Patients completed the QOL questionnaire at baseline, during treatment, and every 6 months through 36 months.
Background: Combining immune checkpoint blockade therapy with operative disruptive immunomodulation using irreversible electroporation may overcome the resistance to systemic therapy found in patients with locally advanced, unresectable pancreatic cancer. We describe the safety profile and efficacy of IRE with nivolumab.
Methods: In the preclinical phase of study, human pancreatic cell lines were cultured with interferon-γ (10 ng/mL) and murine models of pancreatic cancer were treated with irreversible electroporation and programmed death ligand-1 (PD-L1) expression was measured.
Introduction: The purpose of this study was to evaluate the efficacy and tolerability of carfilzomib plus irinotecan (C/I) in patients with relapsed small-cell lung cancer (SCLC).
Patients And Methods: Patients with SCLC who progressed after 1 platinum-containing regimen for recurrent or metastatic disease were eligible. Patients were stratified as: sensitive (SS) (progressive disease > 90 days after chemotherapy) or refractory (RS) (progressive disease 30 to 90 days after chemotherapy) and received up to 6 cycles of C/I; imaging was performed every 2 cycles.
Background: Individuals with cancer experience loss of function and disability due to disease and cancer-related treatments. Physical fitness and frailty influence treatment plans and may predict cancer outcomes. Outcome measures currently used may not provide sufficiently comprehensive assessment of physical performance.

In 2015, the Centers for Medicare and Medicaid Services initiated annual lung cancer screening with a low-dose computed tomography (LDCT) scan. This observational cohort study evaluated the multidisciplinary approach to this screening in our metropolitan community.

Ensuring that blood remains available and safe for transfusion requires sophisticated logistical support, especially for the military community's provision of blood to medical operations around the globe. However, that supply chain may become brittle in future potential operating environments, such as large-scale combat operations where adversaries may contest the U.

The following areas of need were identified: 1) omics and precision oncology, 2) advancing interoperability, 3) patient engagement, and 4) value-based oncology. To begin to address these issues, ASCO convened two complementary workshops: the Omics and Precision Oncology Workshop in October 2016 and the Advancing Interoperability Workshop in December 2016.

Carfilzomib, a novel proteasome inhibitor, was combined with irinotecan to provide a synergistic approach in relapsed, irinotecan-sensitive cancers. Materials and Methods Patients with relapsed irinotecan-sensitive cancers received carfilzomib (Day 1, 2, 8, 9, 15, and 16) at three dose levels (20/27 mg/m2, 20/36 mg/m2 and 20/45 mg/m2/day) in combination with irinotecan (Days 1, 8 and 15) at 125 mg/m2/day.

Methods: Patients with previously untreated mCRC were randomized 1:1:1 to receive continuous axitinib 5 mg twice daily, bevacizumab 5 mg/kg every 2 weeks, or axitinib 5 mg twice daily plus bevacizumab 2 mg/kg every 2 weeks, each in combination with modified 5-fluorouracil/leucovorin/oxaliplatin (FOLFOX-6). The primary endpoint was the objective response rate (ORR).

Purpose: This study was designed to establish the maximum tolerated dose (MTD) and to evaluate tolerability, pharmacokinetics, and antitumor activity of etirinotecan pegol.
Experimental Design: Patients with refractory solid malignancies were enrolled and assigned to escalating-dose cohorts. Patients received 1 infusion of etirinotecan pegol weekly 3 times every 4 weeks (w × 3q4w), or every 14 days (q14d), or every 21 days (q21d), with MTD as the primary end point using a standard 3 + 3 design.
This open-label, phase II study evaluated the antitumor activity and safety of sunitinib monotherapy as maintenance treatment following first-line chemotherapy in patients with locally advanced or metastatic non-small cell lung cancer (NSCLC). Following treatment with standard doublet chemotherapy (paclitaxel and carboplatin), patients received oral sunitinib (starting dose 50mg/day) in 6-week cycles (Schedule 4/2: 4 weeks on treatment, 2 weeks off treatment) until disease progression, unacceptable toxicity or withdrawal of consent. The primary endpoint was probability of survival at 1 year ≥55%.

We hypothesized that tumor p53 biomarkers may predict the efficacy of normal p53 delivered by gene therapy in these patients. EXPERIMENTAL DESIGN: Tumor p53 biomarkers were evaluated in 116 patients, including 29 treated with methotrexate in a phase III randomized controlled trial.

The purpose of this phase II study was to evaluate the safety and efficacy of this combination in chemotherapy-naive pancreatic adenocarcinoma.
Methods: Eligible patients had metastatic and/or locally advanced pancreatic adenocarcinoma, Karnofsky performance status >or=70, creatinine clearance (CrCL) >or=60 mL/min, and acceptable organ function.
Background: This phase II protocol of neoadjuvant chemotherapy with gemcitabine/epirubicin/paclitaxel (GET) was designed to determine the pathologic complete response (pCR) rate in the breast, clinical response rate, disease-free survival, and overall survival at 2 years as well as toxicity in patients with locally advanced breast cancer. This trial also evaluated the feasibility of tissue collection for gene-expression profiling.
Patients And Methods: Seventy-six women with stage IIB, IIIA, and IIIB breast cancer were entered into this trial.
