PURPOSE: To report our early experiences with failure mode and effects analysis (FMEA) in a community practice setting. METHODS: The FMEA facilitator received extensive training at the AAPM Summer School. Early efforts focused on department education and emphasized the need for process evaluation in the context of high profile radiation therapy accidents. A multidisciplinary team was assembled with representation from each of the major department disciplines. Stereotactic radiosurgery (SRS) was identified as the most appropriate treatment technique for the first FMEA evaluation, as it is largely self-contained and has the potential to produce high impact failure modes...

People who have cancer diagnoses often need care throughout their lives through all stages of their illness. These stages include diagnosis, primary treatment, survivorship, and end of life. The management of people with cancer, now a common and chronic illness with long-term survival improving, is complex, challenging, and rapidly changing. Rehabilitation for people with cancer diagnoses is a new specialty and is charged with providing care throughout the trajectory of illness and wellness to maximize potential for function and mitigate disability...

INTRODUCTION: The purpose of this study was to determine the impact of radiation dose to substructures of the heart in lung stereotactic body radiotherapy (SBRT) patients on non-cancer-related deaths. METHODS: Patients treated with lung SBRT at a single institution from 2005 to 2013 were included. The heart and its substructures were contoured, and dose was calculated including mean, max, and max 10 cc dose. Clinical variables including stage, histology, age, gender, Charlson comorbidity index (CCI), preexisting cardiac disease, pulmonary function (forced expiratory volume in 1 second, diffusion capacity), and smoking status were explored for association with non-cancer-related deaths in univariable (UVA) and multivariable (MVA) analyses...

OBJECTIVES: Clinical trials produce the best data available for decision-making in modern evidence-based medicine. We aimed to determine the rate of non-publication of interventional phase 3 and 4 clinical trials involving patients with cancer undergoing radiotherapy. SETTING: The ClinicalTrials.gov database was searched for interventional phase 3 and 4 trials in radiotherapy with a primary completion date before 1 January 2013. We determined how many of these registry entries have not published the compulsory deposition of their results in the database and performed a systematic search for published studies in peer-reviewed journals...

Immobilization devices serve several purposes in radiation oncology including improved positional reproducibility and decreased patient movement. If immobilization device beam attenuation is unaccounted for in the treatment planning process, planning target volume (PTV) coverage can be compromised. A retrospective case study was performed to evaluate beam attenuation from head and neck (HN) immobilization devices in volumetric-modulated arc therapy using the Eclipse treatment planning system and the Anisotropic Analytical Algorithm...

REVIEW
Atif Iqbal, Thomas J George
Surgery remains the mainstay of treatment for colon and rectal cancers. Colon cancer outcomes have improved with laparoscopic techniques, enhanced recovery pathways, and adjuvant chemotherapy. Adjuvant 5-fluorouracil with or without oxaliplatin in stage III and possibly high-risk stage II colon cancer is associated with improved survival. Multimodality management of rectal cancer continues to evolve; total mesorectal excision is the cornerstone. Oncologic results do not support the use of laparoscopic resection in rectal cancer...

Somatic mutation analysis of human cancers has become the standard of practice. Whether screening for single gene variants or sequencing hundreds of cancer-related genes, this genomic information is the basis for precision medicine initiatives in oncology. Genomic profiling results in information that allows oncologists to make a more educated selection of appropriate therapeutic strategies that more often combine traditional cytotoxic chemotherapy and radiation with novel targeted therapies. Here we discuss the nuances of implementing somatic mutation testing in a clinical setting...

Achieving local tumour control is paramount for cure in head and neck and prostate cancers. With the transition to precision radiotherapy (RT) techniques, survival rates have improved in the majority of these cancers, but a substantial proportion of 30-40% still relapse following primary treatment. Recent large-scale molecular profiling studies have revealed unique biological events that could explain for tumour aggression and resistance to therapies, redefining the molecular taxonomy of head and neck and prostate cancers...
