The incidence of breast cancer in female-to-male (FTM) transsexuals who received mastectomy and sex reassignment surgery is very rare. In fact, there is only one previous medical report of such a case. We experienced a case of an FTM transsexual who developed breast cancer 12 years after mastectomy and hysterectomy with bilateral salpingo-oophorectomy. Because he had been continuously receiving testosterone during the last 15 years and because histopathological examination revealed positive estrogen receptor and androgen receptor expression, we suggest that exogenous testosterone may have initiated the development of breast cancer via two distinct pathways. We describe the clinical course and condition of the patient and recommend that medical personnel consider the possibility of hormone-related cancer in FTM transsexuals receiving cross-sex hormones.
Background: 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 cluster 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. 4 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.
IntroductionThe aim of breast reconstruction (BR) is to improve patients’ health-related quality of life (HRQOL). Therefore, measuring patient-reported outcomes (PROs) would clarify the value and impact of BR on a patient’s life and thus would provide evidence-based information to help decision-making. The Satisfaction and Quality of Life After Immediate Breast Reconstruction study aimed to investigate satisfaction and HRQOL in Japanese patients with breast cancer who undergo immediate breast reconstruction (IBR).Methods and analysisThis ongoing prospective, observational multicentre study will assess 406 patients who had unilateral breast cancer and underwent mastectomy and IBR, and were recruited from April 2018 to July 2019. All participants were recruited from seven hospitals: Okayama University Hospital, Iwate Medical University Hospital, The Cancer Institute Hospital of Japanese Foundation for Cancer Research, Showa University Hospital, University of Tsukuba Hospital, Osaka University Hospital and Yokohama City University Medical Center. The patients will be followed up for 36 months postoperatively. The primary endpoint of this study will be the time-dependent changes in BREAST-Q satisfaction with breast subscale scores for 12 months after reconstructive surgery, which will be collected via an electronic PRO system.Ethics and disseminationThis study will be performed in accordance with the Ethical Guidelines for Medical and Health Research Involving Human Subjects published by Japan’s Ministry of Education, Science and Technology and the Ministry of Health, Labour and Welfare, the modified Act on the Protection of Personal Information and the Declaration of Helsinki. This study protocol was approved by the institutional ethics committee at the Okayama University Graduate School of Medicine, Dentistry, on 2 February 2018 (1801-039) and all other participating sites. The findings of this trial will be submitted to an international peer-reviewed journal.Trial registration numberUMIN000032177.
Background One barrier to the widespread use of breast reconstruction (BR) is physicians’ perception that BR adversely affects breast cancer prognosis. However, there is limited information regarding physicians’ understanding of the impact of BR on patient prognosis and which physicians have misunderstandings about BR. Methods We conducted an e-mail survey regarding the impact of BR on the prognosis of patients with breast cancer among members of the Japanese Breast Cancer Society. Results Of 369 respondents, 99 (27%) said that they believe BR affects patient prognosis. Female respondents and those who treat fewer new breast cancer patients per year were more likely to state that they believe BR affects patient prognosis ( P = 0.006 and 0.007). Respondents who believed that BR affects patient prognosis underestimated 5-year overall survival rates in patients who receive BR and subsequently have local or regional recurrence in different sites. Conclusion Our survey demonstrated that a quarter of respondents believe that BR affects patient prognosis and underestimate survival rates in patients who receive BR and have subsequent local or regional recurrence. Because of the lack of evidence regarding the impact of BR on patient prognosis, educating physicians by providing accurate knowledge regarding BR and patient prognosis is highly recommended.
