BACKGROUND: For patients with non-small-cell lung cancer (NSCLC) and multiple brain metastases, whole-brain irradiation (WBI) is a standard-of-care treatment, but its effects on neurocognition are complex and concerning. We compared the efficacy of an epidermal growth factor receptor (EGFR)-tyrosine kinase inhibitor (TKI), icotinib, versus WBI with or without chemotherapy in a phase 3 trial of patients with EGFR-mutant NSCLC and multiple brain metastases. METHODS: We did a multicentre, open-label, parallel randomised controlled trial (BRAIN) at 17 hospitals in China...

INTRODUCTION: Malignant primary brain tumors are one of the most aggressive cancers. Pretreatment serum nonneuronal biomarkers closely associated with postoperative outcomes are of high clinical relevance. The present study aimed to identify potential pretreatment serum biomarkers that may influence oncological outcomes in patients with primary brain tumors. METHODS: A total of 74 patients undergoing supratentorial primary brain tumor resection were enrolled. Before tumor resection, serum neuronal biomarkers, namely neuron-specific enolase (NSE), S100β, and glial fibrillary acidic protein (GFAP), and serum nonneuronal biomarkers, namely neutrophil gelatinase-associated lipocalin (NGAL), lactate dehydrogenase (LDH), and lactate, were measured and associated postoperative oncological outcomes, including brain tumor grading, progression-free survival (PFS), and overall survival (OS), were compared...

Iron oxide nanoparticles, with diameters around 12nm, were synthesized by coprecipitation method. The magnetic properties indicate a superparamagnetic behavior with a coercive field of 9.7Oe and a blocking temperature of 118K. Both aqueous and solid magnetoliposomes containing magnetite nanoparticles have sizes below 150nm, suitable for biomedical applications. Interaction between both types of magnetoliposomes and models of biological membranes was proven. A new antitumor compound, a diarylurea derivative of thienopyridine, active against breast cancer, was incorporated in both aqueous and solid magnetoliposomes, being mainly located in the lipid membrane...

Opioids are commonly used for postoperative pain control in cancer patients. In addition to pain control, an association between opioid use and long-term oncologic outcomes, such as recurrence or overall survival, has been postulated. The aim of this study was to determine whether postoperative opioid use in patients with non-small cell lung cancer is associated with long-term oncologic outcomes, including recurrence and death. Data obtained from 1009 medical records of patients who underwent curative resection at the National Cancer Center, Korea between January 2006 and December 2010 were retrospectively analyzed...

Cancer is a disease of older adults, and the majority of new cancer cases and deaths occur in people 65 years or older. However, fewer data are available regarding the risks and benefits of cancer treatment in older adults, and commonly used assessments in oncology fail to adequately evaluate factors that affect treatment efficacy and outcomes in the older patients. The geriatric assessment is a multidisciplinary evaluation that provides detailed information about a patient's functional status, comorbidities, psychological state, social support, nutritional status, and cognitive function...

The majority of patients with common malignancies are older adults. Intrinsic complex biological changes of aging along with inflammation, immunosenescence, age-associated chronic diseases, and extrinsic environmental and psychosocial factors have significant impact on not only development and behavior of individual malignancies, but also physiologic reserve and vulnerability of older patients who suffer from them. As a result, clinical practice of geriatric oncology demands integration of careful geriatric assessment and management...

BACKGROUND: Geographic access-the travel burden required to reach medical care-is an important aspect of care. Studies, which typically rely on geographic information system (GIS) calculated travel times, have found some evidence of racial disparities in spatial access to care. However, the validity of these studies depends on the accuracy of travel times by patient race. OBJECTIVES: To determine if there are racial differences when comparing patient-reported and GIS-calculated travel times...

Answer questions and earn CME/CNE The concept of frailty has become increasingly recognized as one of the most important issues in health care and health outcomes and is of particular importance in patients with cancer who are receiving treatment with surgery, chemotherapy, and radiotherapy. Because both cancer itself, as well as the therapies offered, can be significant additional stressors that challenge a patient's physiologic reserve, the incidence of frailty in older patients with cancer is especially high-it is estimated that over one-half of older patients with cancer have frailty or prefrailty...

Subsequent to the publication of the above paper, the authors noted that there was an error on Fig. 4 of page 2046, in which the symbols of α-L-fucosidase 1 (FUCA1) and fucosyltransferase 8 (FUT8) had been mistakenly labelled the wrong way around (FUCA1 should have been represented by the blue bars, and FUT8 by the red). The corrected version of Fig. 4 is shown below, which now accurately shows how average levels of FUCA1 mRNA were low in the anaplastic thyroid cancer samples (ATCs), whereas expression levels in the papillary thyroid cancer samples (PTCs) were comparable, or slightly higher, than those present in normal thyroid tissues...

This paper addresses a problem for assignment of chemo-receiving inpatients in an oncology care center, which has not been addressed in the literature. Chemotherapy is regarded as one of the most effective treatments for cancer. In recent years, as cancer incidence increased, the number of patients admitted to a cancer treatment center has also been rising. How to balance the workload of medical service resources by planning admission of patients has become an essential problem that must be given consideration by policy- makers...

Advances in surgical techniques and perioperative care have improved cancer-related outcomes. However, there are still concerns regarding the safety of octogenarian and nonagenarian patients during surgery. Clinicians may be reluctant to perform a radical resection for colorectal cancer and administer adjuvant or palliative cytotoxic chemotherapy to octogenarian and nonagenarian patients. In the elderly, setting a primary goal based on multidisciplinary team discussions prior to treatment is important. The overall treatment scheme, risks, and potential benefits should be discussed with elderly patients and their families...
