An understanding of health-related quality of life (HRQOL) is of utmost importance in both oncological and esthetic breast surgery. The BREAST-Q is a patient-reported outcome (PRO) measure that investigates HRQOL and patient satisfaction before and after breast surgery. The aim of this study was to develop a Japanese version of the BREAST-Q including the mastectomy module, the reconstruction module, the augmentation module and the reduction/mastopexy module, and to assess the psychometric properties of the mastectomy module among Japanese women.
METHODS:
The Japanese version of the BREAST-Q was developed through forward translation, backward translation and patient testing. Traditional psychometric testing of the mastectomy module was administered to 45 post-mastectomy patients.
RESULTS:
The mastectomy, reconstruction, augmentation and reduction/mastopexy modules were formally developed into Japanese. Despite cultural difference between Japanese women and original target population, the contents were considered to be valid among Japanese woman. With the exception of the sexual well-being subscale, good reliability and validity were evident for the mastectomy module (Test-retest reliability 0.76-0.95, Chronbach's alpha coefficient 0.77-0.98).
CONCLUSIONS:
The BREAST-Q Japanese version is a useful PRO measure for investigating the impact of breast surgery on HRQOL and patient satisfaction. Further validation in younger Japanese women is needed to determine the usefulness of the sexual well-being subscale.No potential conflict of interest relevant to this article was reported.Japanese Breast Cancer SocietyActa Medica Okayama1340-68682442017Accuracy assessment methods of tissue marker clip placement after 11-gauge vacuum-assisted stereotactic breast biopsy: comparison of measurements using direct and conventional methods593600ENHidetoshiYatakeDepartment of Radiology, Breast Cancer Center, Kaizuka City HospitalYukaSawai Department of Radiology, Breast Cancer Center, Kaizuka City HospitalToshioNishi Department of Breast Surgery, Breast Cancer Center, Kaizuka City HospitalYoshiakiNakanoDepartment of Breast Surgery, Breast Cancer Center, Kaizuka City HospitalAyakaNishimaeDepartment of Breast Surgery, Breast Cancer Center, Kaizuka City HospitalToshizoKatsudaDepartment of Health Science, Osaka Butsuryo UniversityKoichiYabunakaDepartment of Gerontological Nursing/Wound Care Management, Graduate School of Medicine, University of TokyoYoshihiroTakeda Graduate School of Health Science, Okayama UniversityHideoInaji Department of Breast Surgery, Breast Cancer Center, Kaizuka City HospitalBACKGROUND:
The objective of the study was to compare direct measurement with a conventional method for evaluation of clip placement in stereotactic vacuum-assisted breast biopsy (ST-VAB) and to evaluate the accuracy of clip placement using the direct method.
METHODS:
Accuracy of clip placement was assessed by measuring the distance from a residual calcification of a targeted calcification clustered to a clip on a mammogram after ST-VAB. Distances in the craniocaudal (CC) and mediolateral oblique (MLO) views were measured in 28 subjects with mammograms recorded twice or more after ST-VAB. The difference in the distance between the first and second measurements was defined as the reproducibility and was compared with that from a conventional method using a mask system with overlap of transparent film on the mammogram. The 3D clip-to-calcification distance was measured using the direct method in 71 subjects.
RESULTS:
The reproducibility of the direct method was higher than that of the conventional method in CC and MLO views (P = 0.002, P < 0.001). The median 3D clip-to-calcification distance was 2.8 mm, with an interquartile range of 2.0-4.8 mm and a range of 1.1-36.3 mm.
CONCLUSION:
The direct method used in this study was more accurate than the conventional method, and gave a median 3D distance of 2.8 mm between the calcification and clip.No potential conflict of interest relevant to this article was reported.
