BACKGROUND: Nuclear protein of the testis (NUT) carcinoma (formerly NUT midline carcinoma) is an aggressive tumor defined by the presence of NUT rearrangement with a poor prognosis. This rare cancer is underdiagnosed and poorly treated. OBJECTIVE: The primary objective of this study was to describe the clinical, radiologic, and biological features of NUT carcinoma. The secondary objective was to describe the various treatments and assess their efficacy. METHODS: This retrospective multicenter study was based on review of the medical records of children and adults with NUT carcinoma with specific rearrangement or positive anti-NUT nuclear staining (>50%)...

Modern imaging techniques, particularly functional imaging techniques that interrogate some specific aspect of underlying tumor biology, have enormous potential in neuro-oncology for disease detection, grading, and tumor delineation to guide biopsy and resection; monitoring treatment response; and targeting radiotherapy. This brief review considers the role of magnetic resonance imaging and spectroscopy, and positron emission tomography in these areas and discusses the factors that limit translation of new techniques to the clinic, in particular, the cost and difficulties associated with validation in multicenter clinical trials...

Adenoid cystic carcinoma of the head and neck area is a rare malignant tumor with acceptable short-term but mediocre long-term prognosis. Radical tumor excision with clear resection margins, and sometimes resection of the facial nerve due to perineural growth, remains the fundamental therapy. We present 3 distinct clinical cases and discuss the current therapeutic options with special focus on plastic-reconstructive techniques. For reconstruction, the full armament of local and free flaps, as well as prosthetics, may be necessary...

BACKGROUND: The overexpression of human epidermal growth factor receptor-2 (HER2) in breast cancer is a poor prognosis. Trastuzumab improves overall survival but is associated with cardiotoxicity, especially a decline in left ventricular ejection fraction (LVEF). In addition, chemotherapy and radiotherapy increase fatigue and pain, decrease physical capacity and health-related quality of life. To date, no study has evaluated the benefits of physical activity on the side effects of treatment in patients with HER2 positive breast cancer...

OBJECTIVES: Data supporting the prognostic role of chemotherapy induced haematological toxicity suggest that toxicity-adjusted-dosing (TAD) of chemotherapy might improve treatment efficacy. We tested whether TAD of the cisplatin-etoposide combination might improve the response rate, in previously untreated extensive stage disease (ED)-SCLC patients, as compared with standard fixed-dosing (FD). METHODS: Patients with ED-SCLC were randomized to receive either TAD or FD of cisplatin-etoposide as first-line treatment...

Primary and metastatic liver cancer is an increasingly common and difficult to control disease entity. Radiation offers a non-invasive treatment alternative for these patients who often have few options and a poor prognosis. However, the anatomy and aggressiveness of liver cancer poses significant challenges such as accurate localization at simulation and treatment, management of motion and appropriate selection of dose regimen. This article aims to review the options available and provide information for the practical implementation and/or improvement of liver cancer radiation programs within the context of stereotactic body radiotherapy and image-guided radiotherapy guidelines...

Importance: Even though 15% to 50% of patients with head and neck squamous cell carcinoma (HNSCC) experience recurrence, relatively little is known regarding patterns of treatment failure and postrecurrence outcomes after chemoradiotherapy using modern radiation techniques (intensity-modulated radiotherapy [IMRT]). Recurrence patterns are significantly affected by variations in the quality of radiotherapy, which may confound findings from multicenter trials. Objective: To assess patterns of treatment failure and postrecurrence outcomes for patients with HNSCC treated with contemporary radiotherapy techniques...

REVIEW
Yang Wang, Huifang Zhou, Xianqun Fan
Thyroid-associated orbitopathy (TAO) is an inflammatory autoimmune disorder. The most serious complication of TAO is dysthyroid optic neuropathy (DON), which can lead to permanent vision loss because of volume expansion in the orbital apex. Orbital radiation therapy (ORT) is an anti-inflammatory treatment used in the treatment of active TAO. Clinical studies support radiotherapy as having a modest effect on DON, and early radiotherapy may protect against disease progression to DON. Current studies suggest that radiotherapy is generally safe...

BACKGROUND: Prognosis of patients with glioblastoma multiforme (GBM) remains dismal, with median overall survival (OS) of about 15 months. It is therefore crucial to search alternative strategies that improve these results obtained with conventional treatments. In this context, immunotherapy seems to be a promising therapeutic option. We hypothesized that the addition of tumor lysate-pulsed autologous dendritic cells (DCs) vaccination to maximal safe resection followed by radiotherapy and concomitant and adjuvant temozolomide could improve patients' survival...

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...
