Purpose Treatment of oropharyngeal squamous cell carcinoma (OPSCC) is evolving toward risk-based modification of therapeutic intensity, which requires patient-specific estimates of overall survival (OS) and progression-free survival (PFS). Methods To develop and validate nomograms for OS and PFS, we used a derivation cohort of 493 patients with OPSCC with known p16 tumor status (surrogate of human papillomavirus) and cigarette smoking history (pack-years) randomly assigned to clinical trials using platinum-based chemoradiotherapy (NRG Oncology Radiation Therapy Oncology Group [RTOG] 0129 and 0522)...

Patient-reported outcomes regarding symptom burden may provide valuable information in addition to physician assessment. Systematic collection of patient-reported outcomes may be an important metric to identify unmet needs and improve quality of patient care. To understand common symptoms of patients seen in radiation oncology clinic, we examined the prospectively collected modified Edmonton Symptom Assessment Scale (ESAS-r) data to explore symptom clusters. Our clinic established use of a modified Edmonton Symptom Assessment Scale in August 2015...

BACKGROUND: Merkel cell carcinoma (MCC) is a rare, aggressive tumor that often occurs in the head and neck region. Because of these features, the classifications and diagnostic and treatment regimens are frequently modified. Especially in the anatomically complex head and neck region, it is crucial to be aware of the current recommendations for diagnostics and treatment of MCC to ensure appropriate treatment. This overview aims to summarize the currently available literature. METHODS: The authors reviewed the relevant literature and international guidelines for MCC from 2012 to 2017 with respect to epidemiology and prognosis, diagnostic procedures and imaging, surgery, radiation, systemic treatment, and aftercare...

Answer questions and earn CME/CNE The concept of frailty has become increasingly recognized as one of the most important issues in health care and health outcomes and is of particular importance in patients with cancer who are receiving treatment with surgery, chemotherapy, and radiotherapy. Because both cancer itself, as well as the therapies offered, can be significant additional stressors that challenge a patient's physiologic reserve, the incidence of frailty in older patients with cancer is especially high-it is estimated that over one-half of older patients with cancer have frailty or prefrailty...

PURPOSE: Internists and primary care providers play a growing role in cancer care. We therefore evaluated the awareness of radiation therapy in general and specifically the clinical utility of stereotactic body radiation therapy (SBRT) for early-stage non-small cell lung cancer (NSCLC) among current US internal medicine residents. METHODS AND MATERIALS: A web-based institutional review board-approved multi-institutional survey was distributed to US internal medicine residency programs...

Long-term care for head and neck cancer (HNC) survivors is complex and requires coordination among multiple providers. Clinical practice guidelines highlight the role of primary care providers (PCPs) in screening for secondary cancer/recurrence, assessment of late/long-term side effects, and referrals for appropriate specialty management of toxicity. However, these responsibilities may be difficult to meet within the scope of primary care practice. We conducted this study to explore preferences, comfort, and knowledge of PCPs in the care of HNC survivors...

BACKGROUND/OBJECTIVES: The practice of palliative radiation therapy (RT) is based on extrapolation from adult literature. We evaluated patterns of pediatric palliative RT to describe regimens used to identify opportunity for future pediatric-specific clinical trials. DESIGN/METHODS: Six international institutions with pediatric expertise completed a 122-item survey evaluating patterns of palliative RT for patients ≤21 years old from 2010 to 2015. Two institutions use proton RT...

The goal of regional treatments in breast cancer should be to eradicate any disease within lymph nodes, avoid regional recurrences, minimize the risk of distant metastases, and improve survival. In addition, regional treatments should focus on reducing potential morbidities and optimizing the long-term quality of life of breast cancer survivors. While data from recent surgical and radiation trials have helped clarify many issues regarding regional treatment, there still remains controversy as to the optimal approach for patients with "intermediate risk" disease...

BACKGROUND: An increasing number and proportion of cancer patients with apparently localised disease are treated with chemotherapy and radiation therapy in contemporary oncology practice. In a pilot study of radiation-induced sarcoma (RIS) patients, we demonstrated that chemotherapy was associated with a reduced time to development of RIS. We now present a multi-centre collaborative study to validate this association. METHODS: This was a retrospective cohort study of RIS cases across five large international sarcoma centres between 1 January 2000 to 31 December 2014...

Development of novel therapies for CNS tumors requires reliable assessment of response and progression. This requirement has been particularly challenging in neuro-oncology for which contrast enhancement serves as an imperfect surrogate for tumor volume and is influenced by agents that affect vascular permeability, such as antiangiogenic therapies. In addition, most tumors have a nonenhancing component that can be difficult to accurately quantify. To improve the response assessment in neuro-oncology and to standardize the criteria that are used for different CNS tumors, the Response Assessment in Neuro-Oncology (RANO) working group was established...

BACKGROUND: The Dutch Pancreatic Cancer Group initiated the national, multicentre, controlled PREOPANC trial, randomising between preoperative radiochemotherapy and direct explorative laparotomy for patients with (borderline) resectable pancreatic cancer. The aim of this dummy run is to evaluate compliance with the radiotherapy protocol of this trial, and the quality of delineation and radiation plans. METHODS: Eleven radiation oncology departments open for accrual of patients in the PREOPANC trial were provided with all necessary information of a selected 'dummy' patient...

The aim of this study was to evaluate the curative effect of gamma knife stereotactic body radiotherapy (SBRT) for unresectable massive primary liver cancer. A total of 69 patients with unresectable massive (>10 cm) primary liver cancer who were treated by SBRT at the Department of Radiation Oncology of the 323 Hospital of People's Liberation Army (Xi'an, China) between October, 2006 and October, 2010, were analyzed. According to the Union for International Cancer Control TNM staging guidelines, the patients were graded as stage T1 (n=8), T2 (n=12), T3 (n=21) and T4 (n=28)...

The American Association for Cancer Research convened a meeting of international pediatric oncologists, geneticists, genetic counselors, and radiologists expert in childhood cancer predisposition syndromes (CPS) in October 2016 to propose consensus surveillance guidelines. Imaging plays a central role in surveillance for most, though not all, syndromes discussed. While encompassing the full gamut of modalities, there is increasing emphasis on use of nonionizing radiation imaging options such as magnetic resonance imaging (MRI) in children and adolescents, especially in the pediatric CPS population...

OBJECTIVE: To evaluate the oncologic safety of ovarian preservation (OP) in premenopausal women diagnosed with the International Federation of Gynecology and Obstetrics (FIGO) stage I uterine sarcoma. METHODS: The National Cancer Institute's Surveillance, Epidemiology, and End Results database was accessed and a cohort of women aged ≤50 diagnosed between 1988-2013 with a sarcoma limited to the uterus was drawn. Based on site-specific surgery codes, women who underwent hysterectomy with or without oophorectomy and did not receive radiation therapy were selected for further analysis...
