Surgery precedes both radiotherapy and chemotherapy as the first-line therapy for glioma. However, despite multimodal treatment, most glioma patients die from local recurrence in the resection margin. Glioma surgery is inherently lesional, and the response of brain tissue to surgery includes hemostasis, angiogenesis, reactive gliosis and inflammation. Unfortunately, these processes are also associated with tumorigenic side-effects. An increasing amount of evidence indicates that the response to a surgery-related brain injury is hijacked by residual glioma cells and participates in the local regeneration of tumor tissues at the resection margin...

Nivolumab, a PD-1 immune-checkpoint inhibitor antibody, has been approved in the second line for metastatic squamous non-small cell lung cancer (sqNSCLC)(1). However, only a minority of patients respond to anti-PD-1 immunotherapy, and mechanisms of de novo and adaptive resistance to nivolumab are unclear. There are limited treatment options to rescue the immunotherapy refractory status. We herein describe a patient who was nivolumab refractory and subsequently developed global response after a course of palliative thoracic radiotherapy (RT)...

Background: Craniopharyngiomas are frequent hypothalamo-pituitary tumors in children, presenting predominantly as cystic lesions. Morbidity from conventional treatment has focused attention on intracystic drug delivery, hypothesized to cause fewer clinical consequences. However, the efficacy of intracystic therapy remains unclear. We report the retrospective experiences of several global centers using intracystic interferon-alpha. Methods: European Société Internationale d'Oncologie Pédiatrique and International Society for Pediatric Neurosurgery centers were contacted to submit a datasheet capturing pediatric patients with cystic craniopharyngiomas who had received intracystic interferon-alpha...

Radiation therapy (RT) is a critical treatment modality for patients with brain tumors, though it can cause adverse effects. Recent data suggests that brain RT is associated with dose-dependent cortical atrophy which could disrupt neocortical networks. This study examines whether brain RT affects structural network properties in brain tumor patients. We applied graph theory to MRI-derived cortical thickness estimates of 54 brain tumor patients before and after RT. Cortical surfaces were parcellated into 68 regions and correlation matrices were created for patients pre- and post-RT...

To investigate the targeting accuracy of intensity-modulated SRS (IMRS) plans designed to simultaneously treat multiple brain metastases with a single isocenter. A home-made acrylic phantom able to support a film (EBT3) in its coronal plane was used. The phantom was CT scanned and three coplanar small targets (a central and two peripheral) were outlined in the Eclipse system. Peripheral targets were 6 cm apart from the central one. A reference IMRS plan was designed to simultaneously treat the three targets, but only a single isocenter located at the center of the central target was used...

Previously, we have proposed Erasmus-iCycle, an algorithm for fully automated IMRT plan generation based on prioritised (lexicographic) multi-objective optimisation with the 2-phase ϵ-constraint (2pϵc) method. For each patient, the output of Erasmus-iCycle is a clinically favourable, Pareto optimal plan. The 2pϵc method uses a list of objective functions that are consecutively optimised, following a strict, user-defined prioritisation. The novel lexicographic reference point method (LRPM) is capable of solving multi-objective problems in a single optimisation, using a fuzzy prioritisation of the objectives...

Cervical cancer is the fourth most common malignancy diagnosed in women worldwide. Nearly all cases of cervical cancer result from infection with the human papillomavirus, and the prevention of cervical cancer includes screening and vaccination. Primary treatment options for patients with cervical cancer may include surgery or a concurrent chemoradiotherapy regimen consisting of cisplatin-based chemotherapy with external beam radiotherapy and brachytherapy. Cervical cancer causes more than one quarter of a million deaths per year as a result of grossly deficient treatments in many developing countries...

OBJECTIVES: Epilepsy heavily affects the quality of life (QoL) of patients with brain tumor because in addition to taking treatments for the oncological illness, patients are required to live with the long-term taking of antiepileptic drugs (AEDs). The AEDs' adverse effects are common in these patients and can negatively influence their perceptions of their QoL.We conducted an observational pilot study in patients with brain tumor-related epilepsy to verify efficacy, tolerability, and impact on QoL and global neurocognitive performances of zonisamide (ZNS) in add-on...

PURPOSE: In the randomized G-PCNSL-SG-1 trial, the addition of whole brain radiotherapy (45 Gy) to high-dose methotrexate (HD-MTX)-based chemotherapy (early WBRT arm) did not prolong overall survival (OS) as compared to HD-MTX-based chemotherapy alone (no early WBRT arm) in primary CNS lymphoma (PCNSL) patients. To determine whether WBRT might lead to quality of life (QoL)-relevant late neurotoxicity, this trial prospectively monitored QoL. METHODS: QoL measurements were performed using the EORTC-QLQ-C30 and BN20 questionnaires and combined with repeated Mini Mental State Examinations (MMSE)...

So far most efforts put forth to test the value of predictive and prognostic tools in the field of breast radiotherapy remained globally disappointing, or at least below the convincing levels reached for systemic therapy. Nevertheless the addition of predictive tools to the clinical armament tends to prevail over the use of the sole prognostic factors, also in radiotherapy. A number of predictive assays, clinically validated or not, have recently elicited significant associations between molecular profiles and tumor biological aggressiveness and/or radiosensitivity levels...

Every year, about 650 thousand new cases of Head and Neck Cancer (HNC) are diagnosed globally. Apart from surgery, radiotherapy (RTH), chemotherapy (CHT) or its combination is used in the treatment of HNC. One of the most frequent complications and, at the same time, limitations of RTH is oral mucositis (OM). Proinflammatory cytokines (including TNF-α) play a key role in the development of OM. Genetic alterations, i.e. single nucleotide polymorphisms (SNPs) within genes encoding for receptors for TNF (ie. TNFRSF1A) may change their function...

Stereotactic Body Radiotherapy (SBRT) in the lung is a challenging technique which requires high quality clinical trials to answer the un-resolved clinical questions. Quality assurance of these clinical trials not only ensures the safety of the treatment of the participating patients but also minimises the variation in treatment, thus allowing the lowest number of patient treatments to answer the trial question. This review addresses the role of dosimetry audits in the quality assurance process and considers what can be done to ensure the highest accuracy of dose calculation and delivery and it's assessment in multi-centre trials...

Cancer has become a global problem. On all continents, a great number of people are diagnosed with this disease. In spite of the progress in medical care, cancer still ends fatal for a great number of the ill, either as a result of a late diagnosis or due to inefficiency of therapies. The majority of the tumors are resistant to drugs. Thus, the search for new, more effective therapy methods continues. Recently, nanotechnology has been attributed with big expectations in respect of the cancer fight. That interdisciplinary field of science creates nanomaterials (NMs) and nanoparticles (NPs) that can be applied, e...

Lysosome-associated membrane protein 3 belongs to the lysosome-associated membrane glycoprotein family, which is associated with lymph node, metastasis, poor overall survival, and resistance to chemotherapy and radiotherapy. Epithelial ovarian cancer is one of the most deadly global female gynecologic malignant tumors. Its clinical outcome is poor and most epithelial ovarian cancer patients tend to relapse because of drug resistance. However, lysosome-associated membrane protein 3 expression in epithelial ovarian cancer and its relationship between clinicopathologic factors remain poorly understood...
