Cognitive dysfunction is common among patients with intracranial tumors. Most cognitive deficits are subtle, lack specificity, may mimic depression or other neurological disorders and may be recognized in retrospect by the physician. In certain cases, distinguishing between tumor recurrence and cognitive deficits that arise as a consequence of the treatment becomes challenging. Late treatment effects have also become an area of focus as the overall survival and prognosis of patients with brain tumors increases...

BACKGROUND AND PURPOSE: Incidental irradiation of normal brain tissue during radiotherapy is linked to cognitive decline, and may be mediated by damage to healthy cortex. Non-coplanar techniques may be used for cortical sparing. We compared normal brain sparing and probability of cortical atrophy using 4π radiation therapy planning vs. standard fixed gantry intensity-modulated radiotherapy (IMRT). MATERIAL AND METHODS: Plans from previously irradiated brain tumor patients ("original IMRT", n = 13) were re-planned to spare cortex using both 4π optimization ("4π") and IMRT optimization ("optimized IMRT")...

BACKGROUND: Merkel cell carcinoma (MCC) is a rare and aggressive skin cancer with limited treatment options at advanced stages. There is a paucity of data available regarding the impact of MCC and its management on patients' lives. This study aimed to address this gap by interviewing patients with metastatic MCC entering a trial of an immunotherapy (avelumab). METHODS: In a single-arm, open-label, international, phase 2 trial in patients with stage IV, chemotherapy-refractory, histologically confirmed MCC, patients were invited to participate in semi-structured phone interviews...

A growing body of evidence suggests that individuals with pronounced schizotypal traits also display particular neurophysiological and morphological features - notably with regard to left frontotemporal connectivity. However, the studies published to date have focused on subclinical subjects and psychiatric patients, rather than brain-damaged patients. Here, we used the French version of the Schizotypal Personality Questionnaire to assess schizotypal traits in a sample of 97 patients having undergone surgical resection of a diffuse low-grade glioma...

As survival rates have improved in pediatric patients with leukemia, late side effects from chemotherapeutics and radiotherapy have become important considerations. We investigated these side effects and evaluated their impact on neurocognitive functions. The observational study included 68 patients with acute leukemia who were treated at Eskisehir Osmangazi University Medical Faculty. The study also included 62 of the patients' closest age siblings as a control group. Demographic and clinical data, chemotherapy protocol, use of radiotherapy were recorded, neurological and ophthalmological examinations, cranial imaging, electroencephalography, visual evoked potential, and hearing investigations were performed, and neurocognitive functions were evaluated...

The optimal treatment for patients with low-grade glioma (LGG) WHO grade II remains controversial. Overall survival ranges from 2 to over 15 years depending on molecular and clinical factors. Hence, risk-adjusted treatments are required for optimizing outcome and quality of life. We aim at identifying mechanisms and associated molecular markers predictive for benefit from radiotherapy (RT) or temozolomide (TMZ) in LGG patients treated in the randomized phase III trial EORTC 22033. As candidate biomarkers for these genotoxic treatments, we considered the DNA methylome of 410 DNA damage response (DDR) genes...

BACKGROUND: Treatment for cancer may lead to development of cognitive difficulties in cancer survivors. This study aimed to evaluate long-term cognitive functioning (CogF) in germ-cell tumor (GCT) survivors. Subjects, Materials, and Methods. GCT survivors (n = 155) from the National Cancer Institute of Slovakia completed the Functional Assessment of Cancer Therapy Cognitive Function at a median of 10 years of follow-up (range: 5-32). The study group consisted of survivors receiving a cisplatin-based chemotherapy, radiotherapy to the retroperitoneal lymph nodes, or both, whereas the control group included survivors treated with orchiectomy only...

Clinical management of primary and secondary central nervous system (CNS) malignancies frequently includes radiotherapy to forestall tumor growth and recurrence after surgical resection. While cranial radiotherapy remains beneficial, adult and pediatric brain tumor survivors suffer from a wide range of debilitating and progressive cognitive deficits. Although this has been recognized as a significant problem for decades, there remains no clinical recourse for the unintended neurocognitive sequelae associated with these types of cancer treatments...

Ionizing radiation (IR) is commonly used to treat central nervous system (CNS) cancers and metastases. While IR promotes remission, frequent side effects including impaired cognition and white matter loss occur following treatment. Fractionation is used to minimize these CNS late side effects, as it reduces IR effects in differentiated normal tissue, but not rapidly proliferating normal or tumor tissue. However, side effects occur even with the use of fractionated paradigms. Oligodendrocyte progenitor cells (OPCs) are a proliferative population within the CNS affected by radiation...

The cognitive evaluation is essential to arrest the impact of brain tumours on brain functions. Radiation therapy on the brain has side effects, which can impact on the cognitive functioning. The cognitive disorders constitute a predictive factor of the quality of life of the patients impacting on their autonomy, as well as on their social and professional life. This problem thus takes a more and more important place in the reflection on the cancer care. A better detection of these cognitive disorders requires a better cognitive evaluation from the diagnosis...

Bone sarcomas are rare in childhood, and their presentation can often mimic more benign complaints or chronic musculoskeletal pain. Ewing sarcomas in particular are often diagnosed after a significant delay from the onset of symptoms. At a population level, a long diagnostic delay is not necessarily associated with worse survival , as tumours that display slow growth also tend to be less aggressive. For any specific individual however, a delayed diagnosis can result in a larger tumour that is more difficult to treat...

An increasing number of patients are living with or surviving cancer due to improvements in detection and treatment. However, patients who survive cancer may experience functional disabilities that impact on health, quality of life and ability to work. For example, physical disorders may include fatigue, reduced muscle strength, cognitive dysfunction, paresthesia or nutrition problems, while mental symptoms may include anxiety, depression, fear of relapse or insomnia. Multidimensional oncological rehabilitation programs have been developed to address these disabilities and to help cancer patients and long-term survivors to reduce morbidity and to improve quality of life...

Postprostatectomy incontinence (PPI) is a rare complication of radical prostatectomy, and it may lead to severe limitations for the patient and loss of quality of life. Several different surgical options for the therapy of PPI are available and may be chosen depending on severity of incontinence, residual urethral sphincter function, and previous history of radiotherapy. Alternatives to artificial urinary sphincters which over the last few decades have represented the gold standard for treatment of PPI are fixed slings and adjustable devices...

Brain tumor patients treated with radiotherapy (RT) often develop cognitive dysfunction, and recent studies suggest that the APOE ε-4 allele may influence cognitive outcome. The ε-4 allele is known to promote beta (β) amyloid deposition in the cortex, and preliminary evidence suggests that RT may be associated with this process. However, it is unknown whether β-amyloid accumulation contributes to treatment neurotoxicity. In this pilot study, we assessed neuropsychological functions and β-amyloid retention using18 F-florbetaben (FBB) PET in a subset of brain tumor patients who participated in our study of APOE polymorphisms and cognitive functions...
