Rising cancer incidence and mortality in India emphasize the need to address the increasing burden of this disease and the stark inequities in access to radiotherapy and other essential medical treatments. State-of-the-art technology is available within the private sector and a few hospitals in the public sector, but 75% of patients in the public sector in India do not have access to timely radiotherapy. This inequity in access to radiotherapy in the public sector is amplified in rural areas, where most of India׳s population lives...

The past few years have seen a significant growth of interest in the global radiation therapy (RT) crisis. Various organizations have quantified the need and are providing aid in support of addressing the shortfalls existing in many low-to-middle income countries. With the tremendous demand for new facilities, equipment, and personnel, it is very important to recognize the quality and safety challenges and to address them directly. An examination of publications on quality and safety in RT indicates a consistency in a number of the recommendations; however, these authoritative reports were generally based on input from high-resourced contexts...

Gastric neuroendocrine tumors (NETs) are classified into three types. Type I gastric NETs are associated with chronic atrophic gastritis. They have a good prognosis and endoscopic resection is the mainstay of treatment. Type II gastric NETs are caused by hypergastrinemia. They have a poorer prognosis, and resection is required to control the disease. Endoscopic versus surgical resection is recommended for the gastric lesion. Type III gastric NETs are sporadic and not associated with any specific condition. They have the worst prognosis with the highest rate of metastatic disease, and oncologic resection is recommended...

Confining treatment to the tumor to improve therapeutic outcome and reduce toxicity, is a hot issue in cancer research. Hyperthermia is recognized as a strong sensitizer for radiotherapy and chemotherapy enhancing tumor control without increasing toxicity. Today's electromagnetic hyperthermia systems heat large tissue volumes with limited ability to selectively heat the tumor. Fortunately, tremendous improvements in 3-dimensional electromagnetic & temperature modelling provide an exciting opportunity to design advanced multi-element electromagnetic applicator systems...

Acute care nurses continue to rely on personally created paper-based tools-their "paper brains"-to support work during a shift, although standardized handoff tools are recommended. This interpretive descriptive study examines the functions these paper brains serve beyond handoff in the medical oncology unit at a cancer specialty hospital. Thirteen medical oncology nurses were each shadowed for a single shift and interviewed afterward using a semistructured technique. Field notes, transcribed interviews, images of nurses' paper brains, and analytic memos were inductively coded, and analysis revealed paper brains are symbols of patient and nurse identity...

Hypertension during pregnancy is the most common medical condition encountered during gestation. Despite this, knowledge of the mechanisms that underlie the disease and the development of new therapies are limited. Hypertension during pregnancy and some forms of cancer confer an increased risk to the development of cardiovascular disease later in life; one mechanism which may link these conditions is the involvement of natural killer (NK) cells. Whilst immunology and immunotherapy are well-developed areas in oncology; the complex mechanisms of the immune system in health and disease at the maternal-fetal interface are less well-defined...

Ataxia-telangiectasia is a rare, neurodegenerative, and multisystem disease, characterized by cerebellar ataxia, oculocutaneous telangiectasia, immunodeficiency, progressive respiratory failure, and an increased risk of malignancies. It demands specialized care tailored to the individual patient's needs. Besides the classic ataxia-telangiectasia phenotype, a variant phenotype exists with partly overlapping but some distinctive disease characteristics. This guideline summarizes frequently encountered medical problems in the disease course of patients with classic and variant ataxia-telangiectasia, in the domains of neurology, immunology and infectious diseases, pulmonology, anaesthetic and perioperative risk, oncology, endocrinology, and nutrition...

In the ambulatory care setting, chemotherapy regimens have become increasingly complex with the combination of induction treatments and oral medications. Nurses at one cancer center implemented an oral adherence tracking documentation system in the electronic health record (EHR). Oncology nurses assessed and monitored adherence to oral chemotherapy at each clinical encounter and during telephone calls and then documented findings in the EHR. After implementing this new standardized approach, adherence rates were captured as a metric for the organization...

Metastatic breast cancer (MBC) results in substantial morbidity and mortality for women afflicted with this disease. A majority of MBCs are hormone-responsive and estrogen receptor-positive, making endocrine therapy (ET) an integral component of systemic therapy. With a primary goal of minimizing the effects of estrogen on hormone-responsive MBC, ETs are among the first targeted treatments that aim to inhibit the influence of estrogen receptor activation on tumor proliferation. Several biochemical mechanisms have been the focus of drug development for treatment, including selective estrogen-receptor modulation, aromatase inhibition, and selective estrogen-receptor degradation...

BACKGROUND: The WHO classification of brain tumours describes 15 subtypes of meningioma. Nine of these subtypes are allotted to WHO grade I, and three each to grade II and grade III. Grading is based solely on histology, with an absence of molecular markers. Although the existing classification and grading approach is of prognostic value, it harbours shortcomings such as ill-defined parameters for subtypes and grading criteria prone to arbitrary judgment. In this study, we aimed for a comprehensive characterisation of the entire molecular genetic landscape of meningioma to identify biologically and clinically relevant subgroups...

Precision medicine (PM) is increasingly recognized as the way forward for optimizing patient care. Introduced in the field of oncology, it is now considered of major interest in other medical domains like allergy and chronic airway diseases, which face an urgent need to improve the level of disease control, enhance patient satisfaction and increase effectiveness of preventive interventions. The combination of personalized care, prediction of treatment success, prevention of disease and patient participation in the elaboration of the treatment plan is expected to substantially improve the therapeutic approach for individuals suffering from chronic disabling conditions...

PURPOSE: In recent years, significant progress in survival has been achieved using systemic combination chemotherapy in patients with pancreatic cancer. However, the elderly are largely underrepresented in clinical trials, and gains made from these may not necessarily apply to this important subgroup of patients. We review the currently available data regarding contemporary combination chemotherapy regimens, including FOLFIRINOX, gemcitabine plus nab-paclitaxel, nanoliposomal irinotecan plus 5-fluorouracil and leucovorin, and gemcitabine plus capecitabine, in elderly pancreatic cancer patients...
