David Taylor
This article outlines the historical development of health economics and its present role in oncology related health technology assessments (HTAs). Despite concerns about the prices and immediate costs of new anticancer medicines for indications such as breast cancer overall spending on such treatments is affordable and offers long term value for money in countries such as the US, Canada and those of Western Europe. Oncologists wishing to protect the interests of current and future patients with both advanced and earlier stage cancers may be regarded as having a responsibility to understand the nature of health economic evaluations, and to be actively involved in decisions affecting access to current treatments and future levels of investment in incrementally improving therapies...

Photodynamic therapy is emerging as a hopeful method for the treatment of oncological diseases. In the search of novel therapeutic strategies for colorectal cancer, in this work we reported the photocytotoxic activity of a lipophilic zinc(II) phthalocyanine on a murine colon adenocarcinoma cell line (CT26 cells). The 2,9(10),16(17),23(24) tetrakis[(2-dimethylamino)ethylsulfanyl]phthalocyaninatozinc(II), named Pc9, was encapsulated into Tetronic® 1107 polymeric poloxamine micelles (T1107) and assayed in 2D and 3D cell cultures...

Incretin-based medications (glucagon-like peptide-1 [GLP-1] receptor agonists and inhibitors of dipeptidyl peptidase-4 [DPP-4] are glucose-lowering drugs approved and introduced after 2006 (1). Although both classes of drugs appeared to be relatively safe based on results from clinical trials and standard animal toxicology studies, epidemiological data (2, 3) and histological findings (4) in genetically modified rodents exposed to such agents have raised concern that pancreatitis and pancreatic cancer may be long-term risks associated with this therapy...

Deep Inspiration Breath-Hold (DIBH) techniques for breast cancer radiation therapy (RT) have reduced cardiac dose compared to Free Breathing (FB). Recently, a voluntary deep inspiration breath-hold (vDIBH) technique was established using in-room lasers and skin tattoos to monitor breath-hold. An in-house quality assessment of positional reproducibility during RT delivery with vDIBH in patients with left-sided breast cancer was evaluated. The electronic portal imaging device (EPID) was used in cinematographic (CINE) mode to capture a sequence of images during beam delivery...

Anal metastasis of colorectal cancer is very rare and is usually associated with a history of anal disease, including anal fistula, fissure, hemorrhoidectomy, and anastomotic injury. We report a case of rectal cancer with a synchronous anal metastasis consisting of adenocarcinoma of squamous cells without a history of anal disease. A 60-year-old woman had a chief complaint of melena. She had a 1.5-cm anal tumor on the perianal skin, and a Bollman type 2 rectal tumor on the Ra portion was found on colonoscopy...

The International Association for the Study of Lung Cancer, the American Thoracic Society, and the European Respiratory Society (IASLC/ATS/ERS) proposed a new histologic classification of lung adenocarcinoma in 2011. While several studies have already validated the prognostic value of this new classification of lung adenocarcinoma, we conducted own investigation in the present study. This study included 197 patients with invasive lung adenocarcinoma who underwent complete resection. Pathologic diagnoses were made in accordance with the new IASLC/ATS/ERS classification for lung adenocarcinoma...

PURPOSE: Location of the primary tumor is prognostic and predictive of efficacy with VEGF-inhibitors (I) versus EGFR-I given first-line to metastatic colorectal cancer (mCRC) patients. However, little is known regarding the effect of location on prognosis and prediction in refractory mCRC. We assessed the efficacy of VEGF-I and EGFR-I in regards to location of the primary tumor in patients with refractory mCRC enrolled in early phase studies. METHODS: A historical cohort analysis of mCRC patients, including 44 phase I trials our institution, from March 2004 to September 2012...

Despite multimodal treatment that includes surgery, radiation and chemotherapy, virtually all glioblastomas (GBM) recur, indicating that these interventions are insufficient to eradicate all malignant cells. To identify potential new therapeutic targets in GBMs, we examined the expression and function of proteins that are associated with therapy resistance and cancer cell survival. We measured the expression of eight such proteins in 50 GBM samples by immunohistochemistry and analyzed patient survival. We report that GBM patients with high expression of ABCG2 (also called BCRP) or XIAP at the protein level had worse survival than those with low expression...

Cancer is a leading cause of mortality in the world, with osteosarcoma being one of the most common types among children between 1 and 14 years old. Current treatments including preoperative chemotherapy, surgery and postoperative chemotherapy produce several side effects with limited effectiveness. The use of lipid nanoparticles as biodegradable shells for controlled drug delivery shows promise as a more effective and targeted tumor treatment. However, in vitro validation of these vehicles is limited due to fluid stagnation in current techniques, in which nanoparticles sediment onto the bottom of the wells killing the cells by asphyxiation...

PURPOSE: With an increasing demand for more accurate preoperative staging methods for colon cancer, we aimed to compare preoperative tumour (T)- and nodal (N)-stage in patients with left-sided colon cancer by endoscopic ultrasonography (EUS) and computed tomography (CT) with post-operative histology as gold standard. METHODS: A total of 44 patients were prospectively recruited at Herlev and Roskilde University Hospitals during November 2014-January 2016. Thirty-five patients were included in the final analysis and underwent EUS, CT and surgery within 2 weeks...

BACKGROUND AND AIMS: Staging of colorectal cancer often fails to discriminate outcomes of patients with morphologically similar tumours that exhibit different clinical behaviours. Data from several studies suggest that the gastrin family of growth factors potentiates colorectal cancer tumourigenesis. The aim of this study was to investigate whether progastrin expression may predict clinical outcome in colorectal cancer. METHODS: Patients with colorectal adenocarcinoma of identical depth of invasion who had not received neoadjuvant therapy were included...

Receptor tyrosine kinases (RTK) are important cell signaling molecules that influence many cellular processes. Receptor tyrosine kinase such as orphan receptor 1 (Ror1), a surface antigen, is a member of the RTK family of Ror, which plays a crucial role in cancers that have high-grade histology. As Ror1 has been implicated to be a potential target for cancer therapy, we selected this protein for further investigation. The secondary and tertiary structure of this protein was determined, which revealed that this protein contained three β-sheets, seven α-helices, and coils...

Converging evidence from laboratory models pointed that the widely used antidiabetic drug metformin has direct effects on cancer cells. Thus far, relatively little attention has been addressed to the drug exposures used experimentally relative to those achievable clinically. Here, we demonstrated that metformin loaded on carbon nanotubes under near-infrared (NIR) irradiation led to the remarkably enhancement in response towards cancer cells. The dose of metformin has reduced to only 1/280 of typical doses in monotherapy (35: 10 000-30 000 µM) where the realization of metformin in conventional antidiabetic doses for cancer therapies becomes possible...

IL-35 is an immunosuppressive cytokine and exerts regulatory effects on T cells, B cells, macrophages and dendritic cells. Neutrophils are important innate immune cells that play key roles in tumor development. The effect of IL-35 on neutrophils remains unknown. Here, we report that IL-35 can induce N2 neutrophil polarization (protumor phenotype) by increasing G-CSF and IL-6 production, and promote neutrophil infiltration into tumor microenvironment. The sustained expression of IL-35 could promote chronic inflammation to augment the proangiogenic and immunosuppressive function of neutrophils...

Although, 5-Fluorouracil (5-FU) remains widely used in adjuvant therapy in patients with colon cancer, resistance to 5-FU-based chemotherapy is an important reason for treatment failure. Recent studies have reported that an enhanced reactive oxygen species (ROS) scavenging system shows drug resistance to 5-FU. Peroxiredoxin-2 (PRDX2), is an important member of the ROS scavenging system, and may be a potential target that promotes chemosensitivity to 5-FU in colon cancer. Here, we depleted PRDX2 by PRDX2-shRNA-LV transduction in two colon cancer cell lines and found that in vitro PRDX2 knockdown facilitates cell death and apoptosis in 5-FU-treated colon cancer cells...

BACKGROUND: The BALLET study was an open-label, multicenter, expanded access study designed to allow treatment with everolimus plus exemestane in postmenopausal women with hormone receptor-positive metastatic breast cancer progressed following prior endocrine therapy. A post hoc analysis to evaluate if previous chemotherapy in the metastatic setting affects the safety profile of the combination regimen of everolimus and exemestane was conducted on the Italian subset, as it represented the major part of the patients enrolled (54%)...

Hepatocellular carcinoma (HCC) is a common cancer that frequently over-expresses the c-Myc (Myc) oncoprotein. Using a mouse model of Myc-induced HCC, we studied the metabolic, biochemical and molecular changes accompanying HCC progression, regression and recurrence. These involved altered rates of pyruvate and fatty acid β-oxidation and the likely re-directing of glutamine into biosynthetic rather than energy-generating pathways. Initial tumors also showed reduced mitochondrial mass and differential contributions of electron transport chain Complexes I and II to respiration...
