• W2004363472 abstract "Old and New Symbol Warns of Radiation M. Malekzadeh and B. Eliasy 1 Semnan University of Medical Sciences, Tehran, Iran The black-and-yellow trefoil symbol is the accepted label for denoting radioactive material and it’s hoped that the new symbol will alert more people to the potential dangers of large sources of ionizing radiation and save lives. It has radiating waves, a skull and crossbones and a running person, a new ionizing radiation warning symbol. It was launched by the IAEA and ISO to help reduce needless deaths and serious injuries from accidental exposure to large radioactive sources. The new symbol is aimed at alerting anyone, anywhere to the potential dangers of being close to a large source of ionizing radiation, the result of a five-year project conducted in 11 countries. We have to remember that we can’t teach the world about radiation, but we can warn people about it! Investigation of Differences in VMAT Dose Calculated by Two Treatment Planning Systems W. Zia and O. Ostapiak 1 -McMaster University, Hamilton, Canada 2 -Hamilton Health Sciences Centre, Hamilton, Canada Volumetric modulated arc therapy has gained mainstream appreciation in certain disease sites for its conformal treatments and decreased time of delivery. Two prominent treatment-planning systems, Eclipse and Pinnacle, use differing computational algorithms to compute dose information. We intended to validate the Eclipse calculation of RapidArc in Pinnacle. Eclipse plan information was imported into Pinnacle with all control point information. RapidArc control points were converted to individual beams in the Pinnacle plans to effectively create a 177-beam plan for each arc. Pinnacle plans were combined using Image software. The Eclipse dose grid was imported into the Pinnacle system and plans were evaluated using dose-volume histograms, dose homogeneity and a conformal index. All Pinnacle plans delivered more total dose. Plans were re-normalized by decreasing total Pinnacle dose by an average of 5.385%. After re-normalization, plans displayed by Pinnacle showed inconsistent dose information with respect to doses received to bladder and rectum. These results suggest a clinically significant difference in the calculation model employed by Pinnacle and Eclipse for a VMAT technique. It is important to further examine the causes for such differences in treatment planning software. Socioeconomic Status and Perceived Resource Needs of Cancer Patients and Their Caregivers Undergoing Radiation Therapy at the Odette Cancer Centre M. Vane, W. Tran and C. Gillies 1 -Medical Radiation Sciences Program, Michener Institute for Applied Health Sciences & University of Toronto, Toronto, Canada 2 -Odette Cancer Centre, Sunnybrook Health Sciences Centre, Toronto, Canada Purpose: Socioeconomic status may have a profound effect on a cancer patient’s journey from diagnosis to overall survival. The differential needs of patients and their caregivers have also been elucidated through previous studies that have examined age, gender, income levels and social support systems within this population. To date, socioeconomic status within the Canadian context and the perceived access and utilization to radiation therapy services of patients and their caregivers has not been well described. The aim of this project is to quantify the predictors of socioeconomic status of cancer patients and their caregivers undergoing radiotherapy at the Odette Cancer Centre, Sunnybrook Health Sciences Centre, Toronto, Ontario, with respect to their perceived unmet cancer care needs. 136 Student Programme Abstracts/Journal of Medical Imag Methods: Adult male and female patients and their caregivers who are currently only involved on curative/radical courses of radiation therapy treatment for any disease site will be eligible to participate in this study. The rationale for this inclusion/exclusion criteria is to eliminate the many variables involved in palliative care settings that may skew perceptions and experience. Patients and their caregivers will be approached after two weeks into their course of treatment and given a study questionnaire to evaluate their perceived supportive care needs and evaluate their socioeconomic status. Results: Study subjects will be given a questionnaire that will ask questions to classify the personal characteristics, income-related and occupational variables for both patients and caregivers. Socioeconomic status will be quantified using an established evaluative tool (Hollingshead system). Supportive care needs will be assessed using a questionnaire adapted from established assessment tools (SCNS). Conclusion: Although several studies examine the relationships of socioeconomic status and access to care, many of them do not examine the radiation therapy process, or do not investigate the associations between SES or access to care. Through this proposed project, we look to quantify the predictors of socioeconomic status of cancer patients and their caregivers undergoing radiotherapy at the Odette Cancer Centre, with respect to their perceived unmet cancer care needs. Educating our Patients Collaboratively: A Novel InterProfessional Approach R. Reinhart, L. D’Alimonte, B. Bristow, L. DiProspero and E. Szumacher 1 -Medical Radiation Sciences Program, Michener Institute for Applied Health Sciences & University of Toronto, Toronto, Canada 2 -Odette Cancer Centre, Sunnybrook Health Sciences Centre, Toronto, Canada Background: Radiation therapy treatments can cause a significant amount of emotional anxiety and stress for patients. Patients often experience anxiety due to a lack of information about their treatment and diagnosis. Informational satisfaction is an important way of improving quality of life in cancer patients, and is crucial in meeting the patients’ needs. Educating patients is one way of increasing informational satisfaction. Written material is often utilized to educate patients, but written at a level that is difficult to comprehend. The aim of the present study is to develop an interprofessional group education session and evaluate the usefulness and acceptability of these sessions at our centre. Methods: For this pilot study, prostate patients will be invited to participate in a one-hour group education session. After obtaining written informed consent, participants will attend one of four group education sessions, which will be conducted and facilitated by a multi-disciplinary team of radiation therapists, nurses, social workers and patient support staff. The topics to be covered are related to radiation therapy side effects and management, how radiation therapy works, help for caregivers and more information on support services. Pre-education session participants will complete a demographics questionnaire and self-assess distress levels regarding informational satisfaction, using a validated tool called the Distress Thermometer. Post-education session, the validated Distress Thermometer will be administered again to determine if the session had an effect on the patients’ self-reported distress. They will also be asked to complete an acceptability and usefulness survey post-education session to ensure the format and information presented is clear and acceptable to patients, and to gauge the session’s usefulness. Descriptive statistics will be used to analyze the data obtained from the acceptability survey (Likert items). Open-ended questions will be analyzed via a content analysis for the frequency of specific themes in the survey. Pre-/Post-Distress Thermometer data will be analyzed using a matched pair t-test. Results: Results will be available by March 2012. Conclusions: If the results from the pilot study show the sessions to be acceptable and useful for patients, the center may wish to continue running the sessions for prostate patients. They may also want to expand the sessions from prostate patient sessions exclusively to other site-specific sessions. ing and Radiation Sciences 43 (2012) 135-145" @default.
