OBJECTIVE: To evaluate the effect of tumour volume regression on adaptive treatment planning, reduction in doses to organs at risk (OAR) and dose escalation. METHODS: 20 patients undergoing radical chemoradiotherapy were imaged in fifth week of radiotherapy (CT_45) to evaluate differences in tumour volume regression between concurrent (CONC) and sequential chemoradiotherapy (SEQ). Replanning was done on CT_45 in those with >20% regression (n=10) and evaluated for change in target coverage indices (coverage index [CI], external volume index [EI]) and doses to OAR [mean lung dose, V20 and V5 of whole and ipsilateral lung (MLDWL, V20WL, V5WL, MLDIL, V20IL, V5IL), mean esophagus dose, V50 esophagus and maximum spinal cord doses]...

Bone metastases are common in many advanced solid tumours, being breast, prostate, thyroid, lung, and renal cancer the most prevalent. Bone metastases can produce skeletal-related events (SREs), defined as pathological fracture, spinal cord compression, need of bone irradiation or need of bone surgery, and hypercalcaemia. Patients with bone metastases experience pain, functional impairment and have a negative impact on their quality of life. Several imaging techniques are available for diagnosis of this disease...

Tanycytic ependymoma is a rare variant of ependymoma which has a predilection for the spinal cord. It is a WHO grade II tumour with favourable outcome. Although squash cytology of ependymoma is well described, there is sparse literature available on squash cytomorphology of tanycytic variant. Here we present two cases of squash cytology of tanycytic ependymoma. In the first case the diagnosis of tanycytic ependymoma was considered. However, in the second case a diagnosis of usual ependymoma was offered. Subsequently histopathology confirmed tanycytic nature in both the cases...

Vertebral metastases from primary head and neck cancers are uncommon, and so there are no clear guidelines about management. The spinal cord can be compressed by a vertebral fracture or invasion of a tumour, and may present as an oncological and spinal emergency. The goals of treatment are to relieve pain and maintain neurological function. However, surgical treatments in this group of patients have not been defined, and primary operative treatment of spinal metastases remains controversial. Here we discuss their contemporary management...

INTRODUCTION: Radiotherapy alone still is the most commonly delivered treatment modality for metastatic spinal cord compression (MSCC). MSCC is an emergency situation, which requires treatment as soon as possible. When radiotherapy is performed with the most commonly used approach 10 × 3 Gy (30 Gy in 10 fractions) over 2 weeks, the question has been asked whether an overall treatment time (OTT) of 14-15 days including two weekends without irradiation leads to worse outcomes than OTT of 12 days (beginning of radiotherapy on a Monday resulting in only one weekend break)? METHODS: A total of 412 patients with MSCC were included in this retrospective study...

INTRODUCTION: Role of radiotherapy in comprehensive management of head and neck cancer for achieving tumour control and organ preservation is now well established and radiotherapy is routinely used in adjuvant setting after surgery, concurrently with chemotherapy or targeted agents and for palliation. Development of linear accelerator with Multileaf Collimator (MLC) have revolutionized radiation delivery techniques, allowing conformal and Intensity Modulated Radiotherapy (IMRT) to deliver highly conformal sculpted radiation dose to a very complex structure with improved sparing of adjoining critical structures like salivary glands, spinal cord, eyes, brainstem and larynx amounting to better therapeutic gain...

BACKGROUND: Recently, we described a novel autoantibody, anti-Sj/ITPR1-IgG, that targets the inositol 1,4,5-trisphosphate receptor type 1 (ITPR1) in patients with cerebellar ataxia. However, ITPR1 is expressed not only by Purkinje cells but also in the anterior horn of the spinal cord, in the substantia gelatinosa and in the motor, sensory (including the dorsal root ganglia) and autonomic peripheral nervous system, suggesting that the clinical spectrum associated with autoimmunity to ITPR1 may be broader than initially thought...

In cats, lymphoma (lymphosarcoma) is the most common neoplasm affecting the spinal cord and the second most common intracranial tumour. Although lymphoma commonly develops in the spinal cord as a part of a multicentric process, a primary form may occur. Lymphoma can exhibit a wide range of morphological patterns, including intraparenchymal brain mass, lymphomatosis cerebri, intravascular lymphoma, lymphomatous choroiditis and meningitis, extradural, intradural-extramedullary or intramedullary lymphoma in the spinal cord, or neurolymphomatosis in the peripheral nerves...

BACKGROUND: Angiogliomas are rare low-grade glial tumors with significant vascular components. These tumors are usually seen in the brain, and spinal cord angiogliomas have not been reported in the literature until now. CASE DESCRIPTION: We report the case of a 15-year-old boy with an angioglioma of the medulla and cervicodorsal spine, which was completely excised through a combined suboccipital craniotomy and cervicodorsal laminotomy. The patient experienced excellent clinical recovery after the surgery, and follow-up contrast magnetic resonance imaging showed complete excision of the tumor...

BACKGROUND AND PURPOSE: In this multicentric in silico trial we compared photon, proton, and carbon-ion radiotherapy plans for re-irradiation of patients with squamous cell carcinoma of the head and neck (HNSCC) regarding dose to tumour and doses to surrounding organs at risk (OARs). MATERIAL AND METHODS: Twenty-five HNSCC patients with a second new or recurrent cancer after previous irradiation (70Gy) were included. Intensity-modulated proton therapy (IMPT) and ion therapy (IMIT) re-irradiation plans to a second subsequent dose of 70Gy were compared to photon therapy delivered with volumetric modulated arc therapy (VMAT)...

After the liver and lungs, bones are the third most common sites of cancer metastasis. Palliative radiotherapy for secondary bone tumours helps relieve pain, improve the quality of life and reduce the risk of fractures. Stereotactic body radiotherapy can deliver high radiation doses with very tight margins, which has significant advantages when treating tumours close to the spinal cord. Strict quality control is essential as dose gradient at the edge of the spinal cord is important. Optimal schedule is not defined...

INTRODUCTION: Rhabdoid tumours usually develop in brain and spinal cord or kidney; they are highly malignant neoplasms that typically arise in infancy and early childhood. However, rare cases of pulmonary localization have been described, particularly among young adults. CASE REPORT: A 26-year-old man, smoker, had a right apical lung mass associated with a Pancoast syndrome leading to haemoptysis. There was also a tumour of the left thigh and scalp. Histological samples taken at these three locations were in favour of an undifferentiated carcinoma...

BACKGROUND: Diabetic neuropathic pain (DNP) is severe and intractable in clinic. The specific cellular and molecular mechanisms underlying DNP remain elusive and its treatment are limited. We investigated roles of EphB1 receptor in the development of DNP. METHODS: Diabetic neuropathic pain was produced in male, adult, Sprague-Dawley rats by a single i.p. streptozotocin (STZ) or alloxan. Western blot analysis and immunohistochemistry were used to analyse expression of EphB1 receptor as well as the activation of the glial cells and the pro-inflammatory cytokines in the spinal cord...
