BACKGROUND: The spine is the most common site of skeletal metastases, affecting approximately 30% of individuals with cancer. The aim of surgical treatment for metastatic spine disease is generally palliative to address pain and/or neurologic compromise, significantly improving patients' quality of life. Patients with metastatic spine disease, however, represent a vulnerable cohort and may have comorbidities or previous treatments that impair the structural integrity of spinal hardware...

There is increasing awareness of the special needs for care of the elderly cancer patient. Newer precise conformal radiotherapy techniques allow the safe delivery of higher doses of radiotherapy to the target tumor while reducing the dose to surrounding critical organs. This has led to a shortening of radiotherapy protocols for both curative and palliative indications. We review these novel techniques and protocols and the published clinical studies that include elderly patients treated with these techniques...

INTRODUCTION: High-dose radiotherapy to the hemithorax for patients with malignant pleural mesothelioma is a controversial treatment. Between 2003 and 2013 our institution had a policy of giving hemithoracic radiotherapy to at least 45 Gy. This retrospective study reports survival, progression and toxicity associated with this policy. METHODS: Seventy-one patients with pleural mesothelioma were irradiated with doses of 45-60 Gy. Conformal radiotherapy (3D-CRT) to the lower hemithorax was used for 17 and intensity-modulated radiotherapy (IMRT) to the whole hemithorax for 54 patients...

The main applications of (188)Re in radionuclide therapies include trans-arterial liver radioembolization and palliation of painful bone-metastases. In order to optimize (188)Re therapies, the accurate determination of radiation dose delivered to tumors and organs at risk is required. Single photon emission computed tomography (SPECT) can be used to perform such dosimetry calculations. However, the accuracy of dosimetry estimates strongly depends on the accuracy of activity quantification in (188)Re images...

Although advances in screening mammography have dramatically improved the early detection of breast cancer, a subset of breast cancer cases still present as locally advanced disease. Some of these patients develop fungating lesions, which are difficult to manage and can have a severe impact on the quality of life. Palliative treatment options include surgery, intra-arterial chemotherapy, and radiation therapy. Herein, we describe the case of a patient who presented with a fungating breast mass and demonstrated an immediate and durable response to radiation therapy with a significantly improved quality of life...

PURPOSE: To provide evidence-based, resource-stratified global recommendations to clinicians and policymakers on the management and palliative care of women diagnosed with invasive cervical cancer. METHODS: ASCO convened a multidisciplinary, multinational panel of cancer control, medical and radiation oncology, health economic, obstetric and gynecologic, and palliative care experts to produce recommendations reflecting resource-tiered settings. A systematic review of literature from 1966 to 2015 failed to yield sufficiently strong quality evidence to support basic- and limited-resource setting recommendations; a formal consensus-based process was used to develop recommendations...

Objective To investigate the efficacy and safety of the adjustable transobturator male system (ATOMS) in males with stress urinary incontinence (SUI) after transurethral resection of the prostate (TURP). Materials and methods From a large international prospectively administrated ATOMS-register we identified 49 patients with an ATOMS device due to persistent SUI after TURP. For evaluation males were divided into standard TURP (sTURP) and palliative/post radiation TURP (pTURP). Baseline and follow-up measurements included continence parameters, urodynamics, quality of life surveys (PGI-I, ICIQ-SF) and pain ratings...

PURPOSE: The role of radiotherapy (RT) was largely deserted after the introduction of platinum-based chemotherapy, but still survival rates are disappointingly low. This study focuses on assessing the clinical efficacy of RT in relation to chemotherapy resistance. MATERIALS AND METHODS: From October 2002 to January 2015, 44 patients were diagnosed with epithelial ovarian cancer (EOC) and treated with palliative RT for persistent or recurrent EOC. All patients received initial treatment with optimal debulking surgery and adjuvant platinum-based chemotherapy...

OBJECTIVE Spinal metastases that recur after conventional palliative radiotherapy have historically been difficult to manage due to concerns of spinal cord toxicity in the retreatment setting. Spine stereotactic body radiation therapy (SBRT), also known as stereotactic radiosurgery, is emerging as an effective and safe means of delivering ablative doses to these recurrent tumors. The authors performed a systematic review of the literature to determine the clinical efficacy and safety of spine SBRT specific to previously irradiated spinal metastases...

PURPOSE: In elderly patients with esophageal cancer (EC), esophagectomy is associated with an increased mortality, and therefore these patients are often treated with definite (chemo)radiation. The purpose of this study was to assess the toxicity and efficiency of definite radio(chemo)therapy in patients >75 years compared with definite radio(chemo)therapy in patients <75 years. METHODS: 32 patients >75 years were treated with definite radio(chemo)therapy for EC...

BACKGROUND AND PURPOSE: To evaluate the tolerability and maximum tolerated dose (MTD) of sorafenib administered concurrently with palliative radiotherapy. MATERIAL AND METHODS: In patients with incurable cancer, sorafenib was escalated independently in three cohorts based on irradiation site: thorax, abdomen or pelvis. Sorafenib was administered days 1-28 and radiotherapy (30Gy in 10 fractions) was delivered days 8-12 and 15-19. Dose-limiting toxicities (DLT) were acute grade 3+ toxicities attributable to radiotherapy...

PURPOSE: Palliative radiation therapy (RT) for bone metastases has traditionally been delivered with conventional, nonconformal RT (NCRT). Conformal RT (CRT) is potentially more complex and expensive than NCRT, but may reduce normal tissue dose and subsequently toxicity. In this retrospective analysis, we compared CRT with NCRT to investigate the association between conformality and toxicity. METHODS AND MATERIALS: A retrospective analysis of patients receiving palliative RT for axial skeletal bone metastases from 2012 to 2014 was conducted...

Currently, there is no formal curriculum addressing geriatric oncology within Canadian radiation oncology (RO) residency programs. Knowledge related to geriatric medicine may help radiation oncologists modify RT based on frailty status and geriatric considerations. Understanding specific learning needs allow program coordinators to align the current curriculum with residents' geriatric oncology learning needs. The purpose of this study is to determine the geriatric oncology educational needs of the Canadian RO residents and to inform Canadian RO residency training...
