Novel treatment modalities are necessary for pancreatic cancer. Immunotherapy with immune checkpoint inhibition has shown effect in other solid tumors, and could have a place in pancreatic cancer treatment. Most available clinical studies on immune checkpoint inhibitors for pancreatic cancer are not yet completed and are still recruiting patients. Among the completed trials, there have been findings of a preliminary nature such as delayed disease progression and enhanced overall survival after treatment with immune checkpoint inhibitors in mono- or combination therapy...

BACKGROUND: Patients are often not given the information needed to understand their prognosis and make informed treatment choices, with many consequently experiencing less than optimal care and quality-of-life at end-of-life. OBJECTIVES: To evaluate the efficacy of a nurse-facilitated communication support program for patients with advanced, incurable cancer to assist them in discussing prognosis and end-of-life care. DESIGN: A parallel-group randomised controlled trial design was used...

PURPOSE: To analyze the most recent results of the Imaging and Radiation Oncology Core Houston Quality Assurance Center's (IROC-H) anthropomorphic head and neck (H&N) phantom to determine the nature of failing irradiations and the feasibility of altering credentialing criteria. METHODS: IROC-H's H&N phantom, used for intensity-modulated radiation therapy credentialing for National Cancer Institute-sponsored clinical trials, requires that an institution's treatment plan agrees within ±7% of measured thermoluminescent dosimeter (TLD) doses; it also requires that ≥85% of pixels pass ±4 mm distance to agreement (7%/4 mm gamma analysis for film)...

BACKGROUND AND OBJECTIVES: Hybrid-natural orifice surgery combines the advantages of traditional transabdominal laparoscopic surgery, while limiting surgical trauma to the abdominal wall. Among various routes of intra-abdominal access, the transvaginal method is most appealing because of its utility and proven safety. We describe a series of 4 colonic resections performed with this approach, combined with minilaparoscopy and needlescopic approaches, and discuss the technical aspects, efficacy, and applicability of this technique...

INTRODUCTION: It is an established fact that tumours of ovary inherit a spectrum of histogenetic background, the variety being more than any other organ. Surface epithelial stromal tumours of ovary being the most common type of ovarian tumours form a complicating and baffling subject in the history of oncology and hence, are an interesting topic for study. AIM: The aim of this study was to categorize the surface epithelial tumours of ovary into benign, borderline and malignant, to study their clinical and histopathological pattern and to compare their incidences with other studies...

Historically, the clinical staging of pancreatic cancer has centered on the surgical management of the primary tumor, because few effective chemotherapeutic agents were available and long-term survival was only achieved in the context of surgical resection. Such a strategy of complete oncologic surgical care is reasonable when surgery is both the principal therapy and highly effective. However, complex surgery for pancreatic cancer-often performed in older patients after a lengthy period of induction therapy-can be associated with significant morbidity and mortality...

Red blood cells (RBCs) are naturally capable of transporting diverse cargoes throughout the circulatory system, both loaded to their surface or within their inner volume. Starting largely from the 1970s, diverse approaches for encapsulation into, and surface coupling onto, RBCs have been investigated as potential drug delivery systems. In the last decade, these efforts have yielded diverse strategies to load drugs and nanocarriers to RBCs, and to optimize their pharmacokinetics, distribution, and effects in the body...

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...

BACKGROUND: Studies on factors affecting editorial decisions of scientific journals are scarce. In this study, we focused on case reports submitted to oncology journals and analyzed whether their nature or other relevant variables affected the chances of their acceptance. METHODS: We analyzed case reports submitted to 2 oncology journals: Tumori Journal and The International Journal of Biological Markers, and split them into 3 predefined groups: those (a) describing rare or unusual presentation of diseases, (b) describing the side effects of an intervention or (c) describing the success of a novel intervention...

Cancers are heterogeneous by nature. While traditional oncology screens commonly use a single endpoint of cell viability, altering the phenotype of tumor-initiating cells may reveal alternative targets that regulate cellular growth by processes other than apoptosis or cell division. We evaluated the impact of knocking down expression of 420 kinases in bi-lineage triple-negative breast cancer (TNBC) cells that express characteristics of both myoepithelial and luminal cells. Knockdown of ERN1 or ALPK1 induces bi-lineage MDA-MB-468 cells to lose the myoepithelial marker keratin 5 but not the luminal markers keratin 8 and GATA3...

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)...

BACKGROUND: Biomedical sciences use a variety of data sources on drug molecules, genes, proteins, diseases and scientific publications etc. This system can be best pictured as a giant data-network linked together by physical, functional, logical and similarity relationships. A new hypothesis or discovery can be considered as a new link that can be deduced from the existing connections. For instance, interactions of two pharmacons - if not already known - represent a testable novel hypothesis...

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...
