There is abundant evidence in support of single fraction (SF) radiation therapy (RT) for uncomplicated bone metastases (BoM). We sought to determine the proportion of BoM that is complicated in a population-based RT program in order to act as a potential guide for assessing SFRT utilization rates.A total of 3200 RT courses were prescribed to 1880 consecutive patients diagnosed with BoM in 2013. Associations between choice of RT fractionation and BoM characterization, whether complicated or not, were assessed with logistic regression.The incidence of complicated BoM was 34.4%, resulting most often from adverse features of actual pathological fracture (42.1%), and neurological compromise (36.3%). Complicated BoM were most common in lung cancers (24.2%) and in the spine (68.5%), followed by extremity (15.2%) and pelvis (14.4%). SFRT was prescribed less commonly in complicated versus un-complicated BoM (39.4% vs. 70.4%; p0.001), which was confirmed on multivariable analysis (OR 0.32; 95% CI 0.28-0.61; p0.001).This study found that 34.4% of BoM are complicated by fracture, or neurological compromise (i.e. 65.6% were un-complicated), and that they were less likely to receive SFRT. A reasonable benchmark for SFRT utilization should be at least 60%.

To assess the impact of a population-based intervention to increase the consistency and use of single-fraction radiation therapy (SFRT) for bone metastases.In 2012, an audit of radiation therapy prescriptions for bone metastases in British Columbia identified significant interphysician and -center (26%-73%) variation in the use of SFRT. Anonymous physician-level and identifiable regional cancer center SFRT use data were presented to all radiation oncologists, together with published guidelines, meta-analyses, and recommendations from practice leaders. The use of SFRT for bone metastases from 2007 through 2011 was compared with use of SFRT in 2013, to assess the impact of the audit and educational intervention. Multilevel logistic regression was used to assess the relationship between the usage of SFRT and the timing of the radiation while controlling for potentially confounding variables. Physician and center were included as group effects to account for the clustered structure of the data.A total of 16,898 courses of RT were delivered from 2007 through 2011, and 3200 courses were delivered in 2013. The rates of SFRT use in 2007, 2008, 2009, 2010, 2011, and 2013 were 50.5%, 50.9%, 48.3%, 48.5%, 48.0%, and 59.7%, respectively (P.001). Use of SFRT increased in each of 5 regional centers: A: 26% to 32%; B: 36% to 56%; C: 39% to 57%; D: 49% to 56%; and E: 73% to 85.0%. Use of SFRT was more consistent; 3 of 5 centers used SFRT for 56% to 57% of bone metastases RT courses. The regression analysis showed strong evidence that the usage of SFRT increased after the 2012 intervention (odds ratio 2.27, 95% confidence interval 2.06-2.50, P.0001).Assessed on a population basis, an audit-based intervention increased utilization of SFRT for bone metastases. The intervention reversed a trend to decreasing SFRT use, reduced costs, and improved patient convenience. This suggests that dissemination of programmatic quality indicators in oncology can lead to increased utilization of evidence-based practice.

Purpose There is abundant evidence that a single fraction (SF) of palliative radiation therapy (RT) for bone metastases is equivalent to more protracted and costly multiple fraction courses. Despite this, there is low utilization of SFRT internationally. We sought to determine the utilization of SFRT in a population-based, publicly funded health care system. Methods and Materials All consecutive patients with bone metastases treated with RT during 2007 to 2011 in British Columbia (BC) were identified. Associations between utilization of SFRT and patient and provider characteristics were investigated. Results A total of 16,898 courses of RT were delivered to 8601 patients. SFRT was prescribed 49% of the time. There were positive relationships among SFRT utilization and primary tumor group ( P P P P P P Conclusions The large variability in SFRT utilization across BC Cancer Agency (BCCA) cancer centers suggests there is a strong cultural effect, where physicians' use of SFRT is influenced by their colleagues' practice. SFRT use in BC was similar to that in other Canadian and western European reports but strikingly higher than in the United States. Further work is needed to standardize SFRT prescribing practices internationally for this common indication for RT, with the potential for huge health system cost savings and substantial improvements in patients' quality of life.

Purpose: This study assesses the incidence of distal bone metastases in palliative radiotherapy (RT) patients. Material and methods: All courses of RT for bone metastases from 2007–2011 for patient living in British Columbia (BC) were identified in a provincial RT programme. Treated bone metastases (BoM) were categorized as distal if the BoM was located within or distal to the elbow or knee. Patients were grouped by primary tumour site as breast, lung, prostate gastrointestinal, haematological, melanoma, and other. The incidence of distal bone metastases and associations with primary tumour types were determined. Results: From 2007 to 2011, 8008 patients were treated with 16,277 courses of RT, of which 425 (3%) were courses of RT for distal BoM. The incidence of distal BoM in decreasing order by primary tumour type was melanoma (5%), haematological (3%), lung (2%), other (2%), prostate (2%), breast (1%) and gastrointestinal (1%). Distal BoM where more commonly identified in the lower extremity (87%, p

This study assessed the impact of the distance a patient travelled to the treatment centre on the use of single fraction RT for bone metastases. There was significant variability in the prescription of SFRT by distance at which the patient lives from a cancer centre (p < 0.001).

Objectives/Hypothesis The primary objective was to determine the incidence of second metachronous head and neck cancers (HNC) following an index HNC and estimate their overall survival. Study Design Retrospective cohort study. Methods A total of 1,658 consecutive primary HNC patients diagnosed in 1986 to 1990 were identified through the prospectively maintained provincial BC Cancer Registry database. They were followed up for a period of 25 years. Survival analysis and second cancer estimates were performed with standard Kaplan-Meier & Cox regression analysis. Results Out of a total of 443 (27%) second cancers, 89 (5%) second HNC occurred in 1,658 HNC patients, with an actuarial metachronous HNC incidence rate at 5, 10, 15, 20, and 25 years that was 3.9%, 8.1%, 10.4%, 13.2%, and 14.5%, respectively. Second primary cancer (SPC) in lung and esophagus occurred in 155 (9%) and 32 (2%) patients, respectively. The median follow-up time for all patients and alive patients was 4.05 years (range, 0.2–25.0 years) and 23.2 years (range, 20.76–25.0 years), respectively. Of second HNC, 83 (93%) were metachronous. Oral cavity (P

Summary Objectives Long term outcomes of patients with head and neck cancer (HNC) are rarely reported, but of potential benefit to clinicians and researchers. Squamous cell carcinomas (SCC) of the head and neck represent a heterogeneous group of cancers. The purpose of this population based study is to describe primary site specific, long term outcomes of HNC. Methods All patients from a Canadian province diagnosed between 1986 and 1990 with SCC of the oral cavity, pharynx, and larynx were identified. Chart review and patient data were abstracted through the provincial cancer registry database. Survival analysis was performed with Kaplan Meier methods, while differences in survival between groups were assessed with log-rank tests. Multivariable analysis was performed using Cox-regression. Results 1657 patients were analyzed during the study period. Almost half (50.9%) of the cases were advanced stage (stage III IV) at presentation. Two, 5, 15 & 25 year overall survival (OS) and HNC specific survival for all the patients were 64%, 46%, 21%, 11% and 74%, 63%, 53% & 49%, respectively. OS and HNC-specific mortality were statistically inferior among men, older age at diagnosis, advanced stages of disease, and was primary cancer site specific, with worse survival in oropharyngeal & hypopharyngeal sites, p Conclusions Survival rates vary by primary HNC site, and the overall survival & HNC specific survival differ over this long follow up assessment. Head and neck cancer specific death is most common in the first five years, and is subsequently dominated by competing causes of mortality. These results are useful as a reference tool for clinicians, researchers, and trainees.

Background: The objective of the study was to assess and evaluate the practice patterns of locoregional treatment of early and advanced breast cancer among radiation oncologists (ROs) in India. Materials and Methods: This questionnaire-based survey was served to practicing ROs through electronic mails and personal communication between November 2006 and March 2008. Patterns of practices with respect to locoregional treatment of breast cancer in patients with ductal carcinoma in situ, early breast cancer (EBC), locally advanced and metastatic breast cancer (MBC) were studied. Results: We analyzed sixty completed forms from ROs in India. The median number of breast cancer patients evaluated per year by the treating oncologist was 130, wherein EBC comprised 30%; locally advanced breast cancer (LABC), 50%; and MBC, 20%. A median 46% of the ROs favored breast-conserving therapy (BCT) in EBC and 92% of this subgroup advised adjuvant radiation therapy (RT) in BCT. For LABC, a majority 90% of the respondents advocated a modified radical mastectomy, whereas 42% chose to include the axilla in their RT portals. Conclusions: The survey highlights the prevalent varied treatment policies followed across the country and encourages us to understand and adopt a uniform consensus for the management of breast cancer.

Cancer is already a well-recognized global phenomenon. The traditional approaches to cancer therapy have been surgery, radiotherapy and chemotherapy. These modalities have shown considerable promise and presently form cornerstones of management of most malignancies. However, these conventional approaches have associated toxicities and suffer from limitations in curing advanced lesions. Complementary and alternative medicine (CAM), for reasons varying from cost to accessibility, has assumed significant importance in cancer therapy. In this article, we review the prominent modalities in CAM in present day cancer management and critically analyze their emerging potential into an evidence-based oncology practice.

We present the case of a 67-year-old man with a three month history of right sided facial nerve palsy reporting to our clinic for evaluation of a recently seen suspicious mass in the right lung. Subsequently he was diagnosed with advanced NSCLC right lung and started on palliative chemotherapy. Furthermore, temporal bone metastasis was discovered on radiological imaging while investigating symptoms of acute mastoiditis and persisting facial neuralgia, a symptom completely overlooked at first as Idiopathic Bell's palsy. This presentation is exceptionally unique, although temporal bone metastasis arising from established primary lung or other malignancies is itself rare, and predilect to a later onset in the natural history of the disease, as reported in the literature. None of the published literature report neither addresses the optimal management course nor its subsequent impact on quality of life of patients with temporal bone metastasis.
