Summary

Surgeons at the University of Michigan surveyed adults who had breast removal (mastectomy) as gender surgery at their hospital at least two years earlier. 139 of 235 eligible patients (59%) replied. The typical answers showed full satisfaction and no regret, and nobody had asked the hospital to rebuild their breasts. The authors say this confirms regret is very low. But 41% did not reply, and they had been out of surgery longer, which is when regret is more likely to show up. Thirteen people who scored very high for regret were left out, because the authors assumed they had misunderstood the questions. Typical follow-up was only 3.6 years, and the questionnaires were made for other medical decisions. The study suggests most people who answered were satisfied, but it cannot rule out real regret in the wider group.

Key findings

235 名在 1990 年至 2020 年 2 月間於美國一家大學醫院接受與性別有關的乳房切除的人符合資格，其中 139 人（59%）回覆了調查。
典型患者手術時為 27 歲，回覆者手術後的典型時間為 3.6 年（範圍從 2 年到將近 24 年）。
典型的回答顯示最高的滿意度和零後悔；平均後悔分數為 100 分中的 4 分。
13 人給出了非常高的後悔分數（100 分中的 95 到 100 分），同時又表示滿意，作者假設他們填錯了問卷，因而將他們排除。
未回覆者手術後的時間更長（典型為 4.6 年對 3.6 年），紀錄中有憂鬱（44% 對 68%）或焦慮（44% 對 70%）的比例也較低。
回覆者中約每 5 人就有 1 人（27 人，19%）現在描述的性別與手術時不同；他們典型的後悔分數也是零。
無論是否回覆，沒有人在這家醫院要求或接受過逆轉手術。

Abstract

IMPORTANCE: There has been increasing legislative interest in regulating gender-affirming surgery, in part due to the concern about decisional regret. The regret rate following gender-affirming surgery is thought to be approximately 1%; however, previous studies relied heavily on ad hoc instruments.

OBJECTIVE: To evaluate long-term decisional regret and satisfaction with decision using validated instruments following gender-affirming mastectomy.

DESIGN, SETTING, AND PARTICIPANTS: For this cross-sectional study, a survey of patient-reported outcomes was sent between February 1 and July 31, 2022, to patients who had undergone gender-affirming mastectomy at a US tertiary referral center between January 1, 1990, and February 29, 2020.

EXPOSURE: Decisional regret and satisfaction with decision to undergo gender-affirming mastectomy.

MAIN OUTCOMES AND MEASURES: Long-term patient-reported outcomes, including the Holmes-Rovner Satisfaction With Decision scale, the Decision Regret Scale, and demographic characteristics, were collected. Additional information was collected via medical record review. Descriptive statistics and univariable analysis using Fisher exact and Wilcoxon rank sum tests were performed to compare responders and nonresponders.

RESULTS: A total of 235 patients were deemed eligible for the study, and 139 responded (59.1% response rate). Median age at the time of surgery was 27.1 (IQR, 23.0-33.4) years for responders and 26.4 (IQR, 23.1-32.7) years for nonresponders. Nonresponders (n = 96) had a longer postoperative follow-up period than responders (median follow-up, 4.6 [IQR, 3.1-8.6] vs 3.6 [IQR, 2.7-5.3] years, respectively; P = .002). Nonresponders vs responders also had lower rates of depression (42 [44%] vs 94 [68%]; P < .001) and anxiety (42 [44%] vs 97 [70%]; P < .001). No responders or nonresponders requested or underwent a reversal procedure. The median Satisfaction With Decision Scale score was 5.0 (IQR, 5.0-5.0) on a 5-point scale, with higher scores noting higher satisfaction. The median Decision Regret Scale score was 0.0 (IQR, 0.0-0.0) on a 100-point scale, with lower scores noting lower levels of regret. A univariable regression analysis could not be performed to identify characteristics associated with low satisfaction with decision or high decisional regret due to the lack of variation in these responses.

CONCLUSIONS AND RELEVANCE: In this cross-sectional survey study, the results of validated survey instruments indicated low rates of decisional regret and high levels of satisfaction with decision following gender-affirming mastectomy. The lack of dissatisfaction and regret impeded the ability to perform a more complex statistical analysis, highlighting the need for condition-specific instruments to assess decisional regret and satisfaction with decision following gender-affirming surgery.

Conclusion

In this cross-sectional survey study, the results of validated survey instruments indicated low rates of decisional regret and high levels of satisfaction with decision following gender-affirming mastectomy. The lack of dissatisfaction and regret impeded the ability to perform a more complex statistical analysis, highlighting the need for condition-specific instruments to assess decisional regret and satisfaction with decision following gender-affirming surgery. (Discussion: "While prospective, multicenter work is needed, these results are consistent with previous ad hoc studies and affirm the overwhelmingly low levels of regret following gender-affirming surgery.")

Methodological limitations

Many people did not reply: 96 of 235 eligible patients (41%) did not answer, so we do not know if they regret it. People with regret may be less likely to answer a survey sent by the team that operated on them.
Non-repliers had been out of surgery longer: Those who did not reply typically had surgery 4.6 years earlier, versus 3.6 for those who did. Regret tends to grow over time, so the people most likely to regret it were the ones missing.
High-regret answers thrown out: 13 people (about 9% of those who answered) scored 95–100 out of 100 for regret and were left out as presumed mistakes, because they also said they were satisfied. If even some of these were genuine, regret would be noticeably higher than reported.
Short follow-up: Despite "long-term" in the title, the typical time since surgery was 3.6 years. Detransition and requests for reversal often come 4 to 10 or more years after treatment.
Questionnaires not made for this surgery: Both scales were designed for decisions like menopause hormone treatment or cancer care. Nearly everyone scored at the extreme end, so the authors could not look at who was more likely to regret it, and they call for better tools themselves.
Only reversals at this hospital counted: Breast rebuilding done elsewhere was not captured, so "no reversals" only means none the hospital knew about.
One-time survey relying on memory: A single snapshot cannot show how regret changes over time, and it depends on people looking back on their decision.
One hospital, adults only: Everyone met standard surgical criteria at one university hospital and was an adult (typically 27 at surgery), so the results do not apply to minors or to other clinics.
Surgeons studying their own work: The surgeons who do these operations designed and ran the study, partly funded by a plastic surgery foundation, and patients were surveyed by their own surgical team.
Conclusion goes further than the data: The authors say their results "affirm the overwhelmingly low levels of regret" after gender surgery in general. That is a much bigger claim than a survey of one operation at one hospital, with 59% replying, can support.
