Spine is a common site of metastases in cancer patients. Spine surgery is indicated for select patients, typically those with mechanical instability and/or malignant epidural spinal cord (or cauda equina) compression. Although post-operative conventional palliative external beam radiation therapy has been the standard of care, technical improvements in radiation planning and image-guided radiotherapy have allowed for the application of stereotactic body radiotherapy (SBRT) to the spine. Spine SBRT is intended to ablate residual tumor and optimize local control by delivering several fold greater biologically effective doses...

Current treatments for advanced solid tumors tend to be only palliative. Although radiotherapy is administered with a curative intent, radioresistance and dose-limiting toxicities pose limitations to treatment. Abexinostat, an oral pan-histone deacetylase inhibitor, demonstrated enhanced sensitivity to radiation in various solid tumor cell lines. We conducted an exploratory, phase 1, dose-escalation study of abexinostat in combination with standard hypofractionated radiotherapy in patients with advanced solid tumors treated in a palliative setting...

The use of venovenous extracorporeal membrane oxygenation (VV-ECMO) has traditionally been limited to a narrow set of clinical circumstances, such as acute hypoxic respiratory failure, submassive pulmonary embolism, and cardiopulmonary collapse. Within the pediatric population, there have been cases of VV-ECMO in the context of extrinsic airway compression by a mediastinal mass, typically in the setting of either a lymphoma or germ cell tumors. However, the use of VV-ECMO for adults with extrinsic airway compression is comparatively limited...

Pancreatic adenocarcinoma is one of the most fatal cancers that frequently affects older patients. Limited data suggest that older patients are as likely to benefit from surgery, radiation, and chemotherapy as younger patients. The only potentially curative approach for pancreatic cancer is surgery but this is only performed in less than 20% of patients considered resectable. With improvements in surgical techniques, older patients without major comorbidities show a course of disease after resection similar to that of younger patients...

OBJECTIVE: Patients with hematological malignancies frequently encounter spine-related symptoms, which are caused by disease itself or process of treatment. However, there is still lack of knowledge on their epidemiology and clinical courses. The purpose of this article is to review clinical presentations and surgical results for spinal involvement of hematologic malignancies. METHODS: From January 2011 to September 2014, 195 patients (98 males and 97 females) suffering from hematological malignancies combined with spinal problems were retrospectively analyzed for clinical and radiological characteristics and their clinical results...

Radiation therapy is a well-established palliative treatment for symptomatic metastases from breast cancer. This is also true of symptomatic primary breast tumors in patients with metastatic disease or in those who are medically inoperable. Further, local progression in the chest wall can severely impair quality of life, with local pain, bleeding, and significant impact on one's self-image. Here, we present the case of a patient who showed an exceptional response to a palliative hypofractionated radiation course to her bleeding, fungating breast primary...

INTRODUCTION: Since just after the year 2000 in Quebec, the management of metastatic castration-resistant prostate cancer (mcrpc) has evolved considerably, with the inclusion of docetaxel-based chemotherapy, bone-targeted therapies (zoledronic acid and denosumab), and more recently, abiraterone, enzalutamide, and cabazitaxel for docetaxel-refractory patients. In the present study, we aimed to analyze contemporary mcrpc management patterns and therapy utilization trends in Quebec. METHODS: The study cohort consisted of patients dying of prostate cancer (pca) between January 2001 and December 2013, selected from Quebec public health care insurance databases...

Ovarian cancer is the most lethal of the gynecologic cancers, with 5-year survival rates less than 50%. Most women present with advanced stage disease as the pattern of spread is typically with dissemination of malignancy throughout the peritoneal cavity prior to development of any symptoms. Prior to the advent of platinum-based chemotherapy, radiotherapy was used as adjuvant therapy to sterilize micrometastatic disease. The evolution of radiotherapy is detailed in this review, which establishes radiotherapy as an effective therapy for women with micrometastatic disease in the peritoneal cavity after surgery, ovarian clear cell carcinoma, focal metastatic disease, and for palliation of advanced disease...

PURPOSE: External beam radiation therapy (RT) is an effective palliative treatment for patients with choroidal metastases and is aimed at preserving vision and obtaining local tumor control. Delivery of 30 to 40 Gy in 2-Gy daily fractions is a standard approach at many centers. This study reports the outcomes of a hypofractionated schedule of 20 Gy in 5 fractions in this palliative setting. METHODS AND MATERIALS: We conducted a retrospective review of patients who were treated with RT (20 Gy in 5 fractions) for choroidal metastases between January 1999 and November 2012...

Treatment options for recurrent glioma of brain include chemotherapy, radiotherapy, surgery and palliation. Temozolomide appears to be effective in patients with recurrent high grade gliomas. A middle aged lady had high grade glioma of corpus callosum. Tumour was excised and chemo radiation was given. It was grade 3 anaplastic oligodendroglioma. After 5 years she had significant recurrence. They were not willing for repeat surgery or radiation. She was given temozolomide and dexamethasone intermittently and levetiracetam was continued...

BACKGROUND: In metastatic renal cell carcinoma (mRCC) there has been a treatment shift towards targeted therapy, which has resulted in improved overall survival. Therefore, there is a need for better local control of the tumor and its metastases. Image-guided stereotactic body radiotherapy (SBRT) in bone metastases provides improved symptom palliation and local control. With the use of SBRT there is a need for accurate target delineation. The hypothesis is that MRI allows for better visualization of the extend of bone metastases in mRCC and will optimize the accuracy of tumor delineation for stereotactic radiotherapy purposes, compared with CT only...

INTRODUCTION: The majority of patients with perihilar cholangiocarcinoma (PHC) has locally advanced disease or distant lymph node metastases on presentation or exploratory laparotomy, which makes them not eligible for resection. As the prognosis of patients with locally advanced PHC or lymph node metastases in the palliative setting is significantly better compared with patients with organ metastases, ablative therapies may be beneficial. Unfortunately, current ablative options are limited...

The norepinephrine transporter (NET) is essential for norepinephrine uptake at the synaptic terminals and adrenal chromaffin cells. In neuroendocrine tumors, NET can be targeted for imaging as well as therapy. One of the most widely used theranostic agents targeting NET is metaiodobenzylguanidine (MIBG), a guanethidine analog of norepinephrine. (123)I/(131)I-MIBG theranostics have been applied in the clinical evaluation and management of neuroendocrine tumors, especially in neuroblastoma, paraganglioma, and pheochromocytoma...
