BACKGROUND: Nanoparticle albumin-bound (nab)-paclitaxel was developed to improve paclitaxel solubility and does not need premedication to avoid infusion-related reactions associated with solvent-based (sb)-paclitaxel. We conducted a phase II trial to investigate the efficacy and safety of nab-paclitaxel plus ramucirumab combination therapy for previously treated advanced gastric cancer. PATIENTS AND METHODS: Patients with unresectable advanced gastric cancer refractory to first-line chemotherapy were administered nab-paclitaxel 100 mg/m2 intravenously on days 1, 8 and 15, plus ramucirumab 8 mg/kg intravenously on days 1 and 15 of a 28-day cycle...

The clinical effect of prednisone in metastatic castration-resistant prostate cancer (mCRPC) is unknown. We performed a pooled analysis of control arms of randomized controlled trials that had or had not administered single-agent prednisone. Randomized controlled trials with a control arm that included single-agent placebo (or no anticancer therapy) or single-agent prednisone (with or without placebo) were eligible for analysis. Patients receiving prednisone combined with other agents in the control arm were excluded...

BACKGROUND: Sipuleucel-T is an autologous cell-based cancer immunotherapy for men with asymptomatic or minimally symptomatic metastatic castration-resistant prostate cancer (mCRPC). Its approval by the Food and Drug Administration was based on demonstration of an overall survival (OS) benefit in randomized placebo-controlled phase III trials. However, treatment was associated with a prostate-specific antigen (PSA) decline in only a small minority of patients. Understanding the clinical factors that are associated with OS could help guide treatment decisions, including patient selection and the timing of sipuleucel-T relative to other therapies...

BACKGROUND: The American Joint Committee on Cancer (AJCC) uses the same nodal staging system for cutaneous and mucosal squamous cell carcinoma of the head and neck in its 8th edition (AJCC 8) despite differences in the etiology, risk factors, and clinical behavior of the two diseases. This study aims to evaluate the performance of the AJCC 8 nodal staging system by direct comparison of cutaneous (cSCC) versus oral squamous cell carcinoma (oSCC) patients. METHODS: Patients with metastatic cSCC (N = 382) and oSCC (N = 325) were identified from a prospective database (years 1987-2016)...

The association of anti-EGFR to gemcitabine and oxaliplatin (GEMOX) chemotherapy did not improve survival in biliary tract carcinoma (BTC) patients. Multiple mechanisms might be involved in the resistance to anti-EGFR. Here, we explored the mutation profile of EGFR extracellular domain (ECD), of tyrosine kinase domain (TKD), and its amplification status. EGFR mutational status of exons 12, 18-21 was analyzed in 57 tumors by Sanger sequencing. EGFR amplification was evaluated in 37 tumors by Fluorescent In Situ Hybridization (FISH)...

The dysregulation of the ubiquitously transcribed TPR gene on the X chromosome (UTX) has been reported to be involved in the oncogenesis of several types of cancers. However, the expression and significance of UTX in esophageal squamous cell carcinoma (ESCC) remains largely undetermined. Immunohistochemistry was performed in 106 ESCC patients, and correlated with clinicopathological features and survival. The functional role of UTX in ESCC cells was determined by UTX-mediated siRNA. Univariate analyses showed that high UTX expression was associated with superior overall survival (OS, p = 0...

OBJECTIVES: To measure the usefulness of Ki-67 proliferative index (Ki-67 index) as a prognostic variable for grading pancreatic neuroendocrine tumors. METHODS: A multi-institutional prospective database comprising 350 patients. Grading based on mitotic activity (<2 mitoses/10 high-power fields, 2-20 and >20) and Ki-67 index (<3% per 10 high-power fields, 3%-20% and >20%). Final grade selected based on higher grade of either variable. RESULTS: Most patients were in the less than 3% (n = 158) and 3% to 20% Ki-67 category (n = 107), with a minority being high-grade (Ki-67 > 20%, n = 27)...

OBJECTIVE: To evaluate the changing impact of genetic and clinicopathologic factors on conditional overall survival (CS) over time in patients with resectable colorectal liver metastasis. BACKGROUND: CS estimates account for the changing likelihood of survival over time and may reveal the changing impact of prognostic factors as time accrues from the date of surgery. METHODS: CS analysis was performed in 1099 patients of an international, multi-institutional cohort...

Cardiovascular Magnetic Resonance Imaging (CMR) permits accurate phenotyping of many cardiac diseases. CMR's inherent advantages are its non-invasive nature, lack of ionizing radiation and high accuracy and reproducibility. Furthermore, it is able to assess many aspects of cardiac anatomy, structure and function. Specifically, it can characterize myocardial tissue, myocardial function, myocardial mass, myocardial blood flow/perfusion, irreversible and reversible injury, all with a high degree of accuracy and reproducibility...

Optical spectroscopy (OS) techniques are often coupled with first-principles density functional theoretical (DFT) calculations for determining the precise influence of defects on the electronic and structural properties of two dimensional (2D) TMDs. Such calculations are carried out presuming there is little or no effect of vibrational transitions on the observed electronic spectrum. However, if the effect of change in vibrational energy [Franck Condon (FC) shift] associated with such a transition is large, it could possibly lead to a different origin for the observed peak...

Although nanomedicines have been pursued for nearly 20 years, fundamental chemical strategies that seek to optimize both the drug and drug carrier together in a concerted effort remain uncommon yet may be powerful. In this work, two block polymers and one dimeric prodrug molecule were designed to be coassembled into degradable, functional nanocarriers, where the chemistry of each component was defined to accomplish important tasks. The result is a poly(ethylene glycol) (PEG)-protected redox-responsive dimeric paclitaxel (diPTX)-loaded cationic poly(d-glucose carbonate) micelle (diPTX@CPGC)...

Photovoltaic devices, electrochemical cells, catalysis processes, light emitting diodes, scanning tunneling microscopes, molecular electronics, and related devices have one thing in common: open quantum systems where energy and matter are not conserved. Traditionally quantum chemistry is confined to isolated and closed systems, while quantum dissipation theory studies open quantum systems. The key quantity in quantum dissipation theory is the reduced system density matrix. As the reduced system density matrix is an O(M! × M!) matrix, where M is the number of the particles of the system of interest, quantum dissipation theory can only be employed to simulate systems of a few particles or degrees of freedom...

PURPOSE: Paediatric high grade glioma (pHGG) are rare. Following maximum safe resection, children >3 years with HGG receive radiotherapy as standard of care. Whether the interval from tumour surgery to radiotherapy (ISRT) influences survival is disputed in adults with glioblastoma, data for children are lacking. This retrospective single-centre analysis investigates a possible impact of ISRT on survival in paediatric patients with HGG. METHODS: Survival was analysed in patients aged 3-19 years with non-pontine HGG...

INTRODUCTION: Papillary thyroid carcinoma (PTC) generally shows an excellent prognosis except in cases with aggressive backgrounds or clinicopathological features. Although the cause-specific survival (CSS) of PTC patients has been extensively investigated, the overall survival (OS) of these patients is unclear. We herein investigated both the OS and CSS of a large PTC patient series. MATERIALS AND METHODS: We enrolled 5897 PTC patients who underwent initial surgery between 1987 and 2005 (658 males and 5339 females; median age 51 years)...
