For the past 20 years, we have witnessed an unprecedented and, indeed, rather miraculous event of how cell-penetrating peptides (CPPs), the naturally originated penetrating enhancers, help overcome the membrane barrier that has hindered the access of bio-macromolecular compounds such as genes and proteins into cells, thereby denying their clinical potential to become potent anti-cancer drugs. By taking the advantage of the unique cell-translocation property of these short peptides, various payloads of proteins, nucleic acids, or even nanoparticle-based carriers were delivered into all cell types with unparalleled efficiency...

The pan-Canadian Oncology Drug Review (pcodr) is responsible for making coverage recommendations to provincial and territorial drug plans about cancer drugs. Within the pcodr process, small groups of experts (including public representatives) consider the characteristics of each drug and make a funding recommendation. It is important to understand how the values and preferences of those decision-makers compare with the values and preferences of the citizens on whose behalf they are acting. In the present study, stated preference methods were used to elicit prioritization preferences from a representative sample of the Canadian public and a small convenience sample of pcodr committee members...

BACKGROUND: Natural Orifice Specimen Extraction - NOSE laparoscopy is a promising technique that avoids mini-laparotomy, possibly reducing postoperative pain, wound infections and hospital stay. Recent systematic reviews have shown that postoperative morbidity associated with laparoscopically assisted gastrectomies is similar to that after open gastrectomies. More specifically, there is no difference in wound infection rate. The study objective was to evaluate whether postoperative morbidity and hospital stay may be reduced by transoral specimen extraction after laparoscopically assisted gastrectomy for early gastric cancer...

BACKGROUND: Cervical cancer is the fourth most common cancer among women worldwide, many of who are still within their reproductive lifespan. Advances in screening and treatment have increased the 5-year survival for early stage disease to over 90 % in developed countries. The focus is now shifting to reducing morbidity and improving fertility outcomes for cervical cancer patients. Radical trachelectomy with lymph node assessment became the standard of care for selected women with lesions <2 cm who desire fertility preservation...

Peripherally inserted central catheters (PICCs) are used in a variety of specialties. Infective and thrombotic complications are widely reported but little has been written about the complications of persistent withdrawal occlusion (PWO) or complete luminal occlusion in PICCs. An audit was conducted of all patients who had a PICC in situ for a 6-week period, using a combination of reviewing clinical documentation and local departmental databases, physical review of inpatients and discussion with the relevant clinical nurse specialists in haematology, oncology, outpatient antibiotic therapy and the vascular access team, to determine the degree of PWO or occlusion but also to review possible financial implications in the introduction of a more expensive product...

En bloc resection of tumors involving the spinal column is technically challenging and is associated with high morbidity to the patient due to the proximity of critical neurological and vascular structures and the destabilizing nature of this surgery. Nevertheless, evidence has shown improved progression-free survival with en bloc resection for certain low-grade malignant and aggressive benign musculoskeletal tumors. To avoid the morbidity of en bloc spondylectomy in patients with tumors localized to the lateral and posterolateral spinal column, the authors have found that the goals of surgery can be accomplished through a contralateral osteotomy of the pedicle and posterolateral elements for en bloc resection (COPPER)...

Tyrosine kinase inhibitor-related toxicities have been reported to be predictive and/or prognostic factors in patients affected by metastatic renal cell carcinoma (mRCC). We aim to investigate the incidence of cumulative toxicity and its prognostic role in mRCC patients treated with sunitinib or pazopanib. mRCC patients treated with sunitinib or pazopanib at the European Institute of Oncology in Milan were reviewed for the incidence of adverse events. Cumulative toxicity was defined as the presence of more than one selected adverse event of any grade...

BACKGROUND: When the inframammary fold (IMF) is excised in mastectomy procedures for oncologic reasons, it must be recreated to restore a natural breast shape. Despite refinements in surgical techniques, postoperative loss of a well-defined IMF can occur. This study aimed to assess the outcomes of IMF recreation after two-stage, implant-based breast reconstruction. METHODS: We retrospectively reviewed 75 consecutive patients who underwent unilateral, two-stage, implant-based breast reconstruction between 2013 and 2015 at the authors' institution...

INTRODUCTION: Liver angiosarcoma is a very uncommon tumour of mesenchymal origin, representing between 0.1-2% of all primary tumours of the liver, affecting mainly men in their sixth or seventh decade of life, with a high mortality in the first years (Chaudhary et al., 2015). Literature reports of its surgical treatment vary from a total or partial hepatectomy with or without liver transplant. PRESENTATION OF CASE: A 37year old male, with a 7year history of a fatty liver, was found to have a 12cm diameter tumour in a cirrhotic liver, during an abdominal Computed Tomography (CT) scan...

Radiation therapy (RT), in particular intensity-modulated radiation therapy (IMRT), is becoming a more important nonsurgical treatment strategy in head and neck cancer (HNC). The further development of IMRT imposes more critical requirements on clinical imaging, and these requirements cannot be fully fulfilled by the existing radiotherapeutic imaging workhorse of X-ray based imaging methods. Magnetic resonance imaging (MRI) has increasingly gained more interests from radiation oncology community and holds great potential for RT applications, mainly due to its non-ionizing radiation nature and superior soft tissue image contrast...

Despite remarkable advances in our understanding of the drivers of human malignancies, new targeted therapies often fail to show sufficient efficacy in clinical trials. Indeed, the cost of bringing a new agent to market has risen substantially in the last several decades, in part fuelled by extensive reliance on preclinical models that fail to accurately reflect tumour heterogeneity. In order to halt unsustainable rates of attrition in the drug discovery process we must develop a new generation of preclinical models capable of reflecting the complex heterogeneity found in human cancers...

Natural bicyclic sesquiterpenes, β-caryophyllene (BCP) and β-caryophyllene oxide (BCPO), are present in a large number of plants worldwide. Both BCP and BCPO (BCP(O)) possess significant anticancer activities, affecting growth and proliferation of numerous cancer cells. Nevertheless, their antineoplastic effects have hardly been investigated in vivo. In addition, both compounds potentiate the classical drug efficacy by augmenting their concentrations inside the cells. The mechanisms underlying the anticancer activities of these sesquiterpenes are poorly described...

Based on data obtained from clinical practice analysis (CPA) surveys performed in 2010 and 2013, and with input from its maintenance of certification (MOC) advisory committee, the American Board of Radiology (ABR) recognized that the changing nature of radiation oncology practice patterns warranted revisions of its MOC Part III cognitive examination. One significant revision was the introduction of a modular examination that allowed diplomates to select specific areas of clinical interest. The module-based items represented 30% (60 of 200) of total examination content...

Squamous cell carcinoma (SCC) arising from chronic hidradenitis suppurativa (HS) is rare; however, the morbidity associated with this presentation is high and management has not been standardised or optimised. We present a case of HS of the perineum and buttocks complicated by SCC, requiring multiple extensive surgical resections. Adjuvant radiotherapy was withheld initially because of concern for poor healing of the surgical wound but was eventually initiated after a second recurrence was identified. The patient ultimately expired 4 years after the initial diagnosis of SCC...

Oral mucositis is a major clinical challenge in oncology and is characterized by pain and inflammation of the mucous membrane surface resulting from radiotherapy for head and neck cancer or from chemotherapeutic agents. Manifestations range from a burning sensation to ulcer formation that affect the patients' quality of life by producing pain and discomfort on swallowing, ultimately leading to malnutrition and dehydration. Due to complications arising from the use of chemical drugs, in recent decades, increasing attention has been paid to natural-based agents...

Positron emission tomography (PET) combined with computed tomography (CT) is an established diagnostic modality that has become an essential imaging tool in oncological practice. However, thanks to its noninvasive nature and its capability to provide physiological information, the main applications of this technique have significantly expanded.(18)F-labelled fluorodeoxyglucose (FDG) is the most commonly used radiopharmaceutical for PET scanning and demonstrates metabolic activity in various tissues. Since activated inflammatory cells, like malignant cells, predominantly metabolise glucose as a source of energy and increase expression of glucose transporters when activated, FDG-PET/CT can be successfully used to detect and monitor a variety of lung diseases, such as infections and several inflammatory conditions...
