Patients with a rare bone cancer of the skull and spine – chordoma – could be helped by existing drugs, suggest scientists from the Wellcome Trust Sanger Institute, University College London Cancer Institute and the Royal National Orthopaedic Hospital NHS Trust. In the largest genomics study of chordoma to date, published today in Nature Communications, scientists show that a group of chordoma patients have mutations in genes that are the target of existing drugs, known as PI3K inhibitors.

CONCLUSIONS: We conclude that women may potentially receive Pap tests even if they are not at risk for cervical cancer, and may not be adequately informed about the need for screenings. We recommend strategies to disseminate recommendations and information to patients, their families, and care providers.

In recent years, a number of studies have been reported on the various types of cancer arising from epigenetic alterations, including reports that these epigenetic alterations occur as a result of radiation exposure or infection. Thyroid cancer and breast cancer, in particular, have high cancer burden, and it has been confirmed that radiation exposure or onco-viral infection are linked to increased risk of development of these two types of cancer, respectively. Thus, the environment-epigenetic alteration-cancer occurrence (EEC) hypothesis has been suggested. This paper reviews the trends in…

The goal of these studies was to use a tumor-targeting, near-infrared (NIR) fluorescent peptide to evaluate early detection and to guide surgical removal of polyps in a genetically engineered rat model of spontaneous colorectal cancer. This peptide, LS301, was conjugated to Cy7.5 and applied topically to the colon of adenoma-bearing Pirc rats. Ten minutes after administration, rats underwent targeted NIR laser colonoscopy. Rats were also evaluated by white light colonoscopy and narrow-band imaging, for comparison to the NIR technique. Unlik…

Publication date: Available online 5 August 2018Source: Journal of Molecular BiologyAuthor(s): Seungyoon B. Yu, Gulcin PekkurnazAbstractTo maintain homeostasis, every cell must constantly monitor its energy level and appropriately adjust energy, in the form of ATP, production rates based on metabolic demand. Continuous fulfillment of this energy demand depends on the ability of cells to sense, metabolize, and convert nutrients into chemical energy. Mitochondria are the main energy conversion sites for many cell types. Cellular metabolic states dictate the mitochondrial size, shape, function and positioning. Mitochondrial s…

AbstractPrimary malignant bone tumors are uncommon and heterogeneous malignancies. This document is a guideline developed by the Spanish Group for Research on Sarcoma with the participation of different specialists involved in the diagnosis and treatment of bone sarcomas. The aim is to provide practical recommendations with the intention of helping in the clinical decision-making process. The diagnosis and treatment of bone tumors requires a multidisciplinary approach, involving as a minimum pathologists, radiologists, surgeons, and radiation and medical oncologists. Early referral to a specialist center could improve pati…

As an alternative to conventional photon-based radiotherapy, radiation with protons is recognised to offer considerable advantages. Today, central nervous system tumours, various sarcomatous tumours, childhood cancer and head and neck tumours are commonly treated with proton therapy. This review evaluates current data from clinical and dosimetric trials on the treatment of selected sarcomatous tumours like rhabdomyosarcoma, osteosarcoma, chordoma, chondrosarcoma and Ewing sarcoma. Special considerations for paediatric tumours and future prospects of proton therapy are outlined.

Chordoma is a rare primary bone cancer with limited treatment options. Surgical resection followed by radiotherapy has proven effective; however, when in 30‐40% of patients tumours recur and metastasize, high resistance to chemotherapies leaves these patients with a dearth of treatment options. Recent work published in the Journal of Pathology by Scheipl, et al describing a focused compound drug screen highlights the significance of EGFR signalling in chordoma and shows potential for EGFR inhibitors as a way forward toward developing an effective treatment for chordoma. Importantly, combining EGFR inhibitors wit…
