Bone sarcomas are extremely rare representing approximately 0.2% among all cancer types. Due to the rarity of these tumors both the patients and the physicians can overlook or misinterpret the first often unspecific symptoms of these tumors (pain, limping and swelling). Therefore, radiographic examination (X-ray and/or MRI) of the involved region in case of inexplicable symptoms is strongly recommended. The most common primary malignant bone tumor entity is osteosarcoma, followed by chondrosarcoma and Ewing sarcoma...

BACKGROUND: Radiation therapy is a major treatment option in the management of primary central nervous system (CNS) tumors, though recurrences after primary treatment, especially in high-grade glial tumors, is a challenge for treating physician. Advances in the field of radiation have made reirradiation a feasible option in recurrent CNS tumors. MATERIALS AND METHODS: Details of patients with primary CNS lesions who presented between 2009 and 2016, with recurrent CNS lesions, and who were treated with reirradiation were retrieved from electronic medical records, as a departmental audit, and the outcome was analyzed...

With radiotherapy having entered the era of image guidance, or image-guided radiation therapy (IGRT), imaging procedures are routinely performed for patient positioning and target localization. The imaging dose delivered may result in excessive dose to sensitive organs and potentially increase the chance of secondary cancers and, therefore, needs to be managed. This task group was charged with: a) providing an overview on imaging dose, including megavoltage electronic portal imaging (MV EPI), kilovoltage digital radiography (kV DR), Tomotherapy MV-CT, megavoltage cone-beam CT (MV-CBCT) and kilovoltage cone-beam CT (kV-CBCT), and b) providing general guidelines for commissioning dose calculation methods and managing imaging dose to patients...

PURPOSE OF REVIEW: The overview summarizes recent developments in radiation oncology for high risk and recurrent prostate cancer. RECENT FINDINGS: A number of well known phase III prostate hypofractionated radiation therapy (HFxRT) trials were finally published with long-term follow-ups. These trials demonstrate patterns of equivalent tumor control with several showing worse toxicity rates. The ASCENDE-RT randomized trial demonstrated the superiority of brachytherapy boost in intermediate and high-risk prostate cancer...

PURPOSE: Radiation-induced skin injury represents one of the most common side effects in breast cancer patients receiving adjuvant whole-breast radiotherapy. Numerous systemic and topical treatments have been studied in the prevention and management of radiation-induced skin injury without providing sustainable treatment strategies. While superficial barrier-forming skin products such as dressings are the standard of care in wound care management, their utilization as preventive treatment approach in radiotherapy has barely attracted attention...

BACKGROUND: After radical cystoprostatectomy (RC), postoperative erectile dysfunction (ED) is a common consequence with multiple contributing etiologies. The inflatable penile prosthesis (IPP) offers patients a definitive treatment option when ED is refractory to medical therapies. Because of the hostile postoperative anatomy of these patients, a careful surgical approach is necessary for successful outcomes and to avoid adjacent organ injury. To date, there is no series describing the outcomes of 3-piece IPP placement in patients with urinary diversions...

Background: Recent trials in early-stage breast cancer support hypofractionated whole-breast radiotherapy (WBRT) as part of breast-conserving therapy (BCT). Evidence also suggests that radiotherapy (RT) omission may be reasonable for some patients over 70 years. Among radiation-delivery techniques, intensity-modulated RT (IMRT) is more expensive than 3-dimensional conformal RT (3DCRT). Based on this evidence, in 2013, the American Society for Radiation Oncology (ASTRO) recommended hypofractionated schedules for women aged ≥50 years with early-stage breast cancer and avoiding routine use of IMRT for WBRT...

PURPOSE: Readmission within 30 days has been used as a metric for quality of care received at hospitals for certain diagnoses. In the era of accountability, value-based care, and increasing cancer costs, policymakers are looking into cancer readmissions as well. It is important to describe the readmission profile of patients with cancer in the most clinically relevant approach to inform policy and health care delivery that can positively impact patient outcomes. PATIENTS AND METHODS: We conducted a retrospective cohort study using linked Texas Cancer Registry and Medicare claims data...

BACKGROUND: As in other brain tumors, multiple recurrences after complete resection and irradiation of supratentorial ependymoma are common and frequently result in patient death. This standard-of-care treatment was established in the pre-genomic era without the ability to evaluate the effect that mutagenic therapies may exert on tumor evolution and in promoting resistance, recurrence, and death. We seized a rare opportunity to characterize treatment effects and the evolution of a single patient's ependymoma across four recurrences after different therapies...

A diagnosis of head and neck cancer (HNC) is typically followed by therapy that is associated with immediate and long-lasting toxic consequences. HNC patients' oral health needs may be complex and are best addressed in multidisciplinary collaborative teams including surgical, medical, and radiation oncologists, dental providers, nutrition, speech/swallow specialists, and physical therapists. Oral health maintenance also requires patient compliance and caregiver support. The role of dental providers begins prior to cancer diagnosis and continues through survivorship...

This chapter explores the role of advanced practice clinicians (APCs) and patient care coordinators in the head and neck cancer setting. APCs, which include physician assistants (PAs) and nurse practitioners (NPs), are licensed professional healthcare providers who diagnose and treat illnesses, order and interpret diagnostic tests, and prescribe pharmaceutical and non-pharmaceutical therapies. Although the training, education, and licensure differ between PAs and NPs, their roles are quite similar in head and neck surgery...

As palliative care (PC) moves upstream in the course of advanced illness, it is critical that PC providers have a broad understanding of curative and palliative treatments for serious diseases. Possessing a working knowledge of radiation therapy (RT), one of the three pillars of cancer care, is crucial to PC providers given RT's role in both the curative and palliative settings. This article provides PC providers with a primer on the vocabulary of RT; the team of people involved in the planning of RT; and common indications, benefits, and side effects of treatment...

BACKGROUND: A paucity of data exists in the use of neoadjuvant chemoradiation therapy (NRT) for T4, non-metastatic colon cancer. This study was conducted to determine the effect of NRT on outcomes after resection for T4 colon cancer. METHODS: All patients with non-metastatic resected clinical T4 colon cancer from 2000 to 2012 at a tertiary care center were included. The cohort was divided into two groups-those that received NRT and those that did not (non-NRT). The primary outcomes were margin-negative resection and overall survival (OS)...

We have performed a narrative synthesis. A literature search was conducted between January 2000 and June 2014 in 7 databases. The initial search identified 2717 articles; 319 underwent abstract screening, 67 underwent full-text screening, and 25 final articles were included. This review looked at early stage breast cancer in women only, excluding ductal carcinoma in situ and advanced breast cancer. A conceptual framework was created to organize the central constructs underlying women's choices: clinicopathologic factors, physician factors, and individual factors with subgroups of sociodemographic, geographic, and personal beliefs and preferences...
