- W2293399144 abstract "Whole breast irradiation (WBI) is the standard regimen of radiation therapy following lumpectomy for early stage breast cancer. Recently, interest in partial breast irradiation (PBI) as an alternative to WBI has increased. However, the preference of patients as to what type of radiation therapy regimen they would prefer and why is unclear in the literature. This study was conducted to determine whether patients with early stage breast cancer prefer PBI or WBI and to identify important factors for patients when making this decision. Based on our previous study of early stage breast cancer patient information needs, the relevant literature and the ASTRO consensus statement guidelines, an educational tool and questionnaire were developed. New patients with early stage breast cancer referred for adjuvant radiation therapy at a large academic cancer center were invited to participate. Women over age 40 with a new diagnosis of breast cancer treated with breast conserving surgery showing clear margins and negative axillary nodes were eligible. Descriptive statistics were calculated for all variables. Responses to survey questions were compared between patients who preferred WBI versus PBI using Chi-square analyses or Fisher’s exact tests. One hundred twenty-six patients were approached and 90 completed the survey. Twenty-seven (30%) preferred PBI and 55 (61%) preferred WBI. Eight patients (9%) either required more information or had no preference. Of the patients who chose WBI, 32 (58%) preferred hypofractionated radiation therapy while 14 (26%) preferred conventional radiation therapy and nine (16%) had no preference. Patients rated several factors as important, including convenience [PBI = 18/26 (69%), WBI = 36/54 (67%)], radiation dose [PBI = 20/26 (80%), WBI = 46/55 (83%)], invasiveness [PBI = 18/26 (69%), WBI = 43/53 (81%)], recurrence rate [PBI = 26/26 (100%), WBI = 55/55 (100%)], survival [PBI = 26/26 (100%), WBI = 54/55 (98%)], side effects [PBI = 21/26 (81%), WBI = 47/55 (85%)] effectiveness [PBI = 25/26 (96%), WBI = 54/54 (100%)] and radiation dose to surrounding organs [PBI = 23/26 (88%), WBI = 52/54 (95%)]. The only factor that was significantly different between the groups was standard method of treatment [PBI = 16/26 (61%), WBI = 52/54 (96%), chi-square = 16.63, p = 0.001]. Our study shows that patients with early breast cancer prefer WBI as an adjuvant treatment post lumpectomy. There is significant association between treatment preference and the rating of standard treatment as important. Patients preferring WBI were more likely to consider standard treatment as important compared to those preferring PBI. A detailed analysis of all decisional preferences between WBI and PBI will be presented at the meeting." @default.
