Breast cancer found at the time of breast reduction

Pathological Evaluation of Breast Specimens in Transgender Chest Masculinization: Incidental Findings and Effect of Prior Chest Binding and Androgen Therapy in 74 Consecutive Patients

Background: The rate of masculinizing chest surgery for gender affirmation continues to increase. With a paucity of literature on pathological evaluation of breast specimens in this patient population, there is a need for these data and for protocols on the handling of these specimens. Methods: A retrospective chart review was performed between 2015 and 2020 on all patients who underwent chest masculinization surgery for gender dysphoria by the senior author (J.D.K.). Inclusion criteria were any patient with sex assigned female at birth who underwent removal of breast and/or nipple areolar complex tissue for gender affirmation. Patient demographics were recorded. Bilateral breast tissue was sent for routine pathology in all cases and findings were recorded. A p-value of <0.05 was considered significant. Results: Seventy-four consecutive patients and 148 breast specimen reports were identified from a database and included in the study. The mean age was 26 years (15-49). Thirty-nine patients had a known history of chest wall binding and 60 patients had undergone preoperative androgen therapy. There was no invasive or in situ carcinoma found in any breast tissue specimens. Thirty-four patients had a benign lesion in one or both breast specimens. Atypical lobular hyperplasia was found in one patient's specimen. A history of chest wall binding was not correlated with any benign lesions (p=0.79) or stromal fibrosis (p=0.94). A history of testosterone use was not correlated with any benign lesions (p=0.35) or stromal fibrosis (p=0.20). Conclusions: The prevalence (1.4%) of significant breast pathology and of benign findings (46%) in our study closely correlates with the rates in the literature. We found no correlation between significant breast pathology or benign lesions and a history of chest wall binding or preoperative androgen therapy. We recommend all breast specimens removed during chest masculinization surgery be sent for pathological evaluation.

Pathology Evaluation of Reduction Mammaplasty Specimens and Subsequent Diagnosis of Malignant Breast Disease: A Claims-Based Analysis

BACKGROUND

This study aimed to measure the use of pathology evaluation of breast specimens among patients undergoing reduction mammaplasty and assess rates of new diagnoses of breast disease and associated cost.

METHODS

We analyzed the Truven MarketScan Databases from 2009 to 2015 to identify adult female patients undergoing reduction mammaplasty for macromastia. We recorded patient age, rates of obtaining pathology evaluation, new diagnoses of benign or malignant breast disease after pathology evaluation, and total cost for the surgery encounter.

RESULTS

Among 17,738 macromastia patients undergoing reduction mammaplasty, 91.3% (n = 16,193) received pathology evaluation. Pathology evaluation rates were clinically similar across age groups <70 years (90.8-92.1%) and slightly lower for patients ≥70 (85.0%). Among 6987 patients less than 40 years who received pathology evaluation, 0.06% (n = 4) were subsequently diagnosed with malignant breast disease within 3 months, compared to 0.23% in the entire cohort (n = 37/16,193). Pathology claims resulted in an added $307 (SD 251) on average for the breast reduction surgery encounters.

CONCLUSIONS

Breast tissue after reduction mammaplasty is routinely submitted for pathology evaluation, without consideration of age-based risk for breast cancer. Routine pathology evaluation of breast tissue in patients in lower risk age groups (less than 40 years) required an additional $536,000 on average to detect a single occult breast cancer compared to an added $85,600 to detect a new malignancy in patients 40 years and older. Clinicians and policy makers should consider whether routine pathology evaluation of breast tissue should be individualized based on risk factors for breast cancer.

Breast Cancer Found Incidentally After Reduction Mammaplasty in Young Insured Women

BACKGROUND

Reduction mammaplasty is a common operation performed for healthy women. The estimated incidence of breast cancer diagnosed at the time of reduction mammaplasty varies from 0.06 to 4.5%, and information on the care of these patients is limited. This study aimed to determine the incidence of breast cancer identified incidentally during reduction mammaplasty and to characterize preoperative imaging.

METHODS

Women 18 years of age or older who underwent reduction mammaplasty from 2013 to 2015 were identified from the Truven Health MarketScan^® Research Databases. Patients with prior breast cancer were excluded. Descriptive statistics were calculated for patient characteristics, incidental breast cancer, preoperative breast imaging, and postoperative treatment.

RESULTS

Reduction mammaplasty was performed for 18,969 women with a mean age of 42.5 years. Of these patients, 186 (0.98%) were incidentally found to have breast cancer, with 134 (0.71%) having invasive breast cancer and 52 (0.27%) having carcinoma in situ. The patients with incidentally found cancer were older than the patients without cancer (50.8 vs. 42.5 years; p < 0.001). Overall, 58.2% of the patients had undergone mammography before reduction mammoplasty. The rates were higher (> 80%) for the patients older than 40 years. Preoperative mammography was performed for 76.3% of those with a diagnosis of breast cancer at time of reduction mammoplasty.

CONCLUSIONS

Breast cancer diagnosed incidentally at the time of reduction mammaplasty is uncommon and often radiographically occult. The majority of women older than 50 years appropriately received preoperative mammography. These data can be used to manage patient expectations about the potential for the incidental diagnosis of breast cancer at reduction mammaplasty, even with a negative preoperative mammography.

Occult disease in reduction mammoplasties and prophylactic mastectomies

The aim of this study was to determine the incidence of occult breast carcinoma and significant breast disease in clinically and radiologically unremarkable breast reduction specimens and prophylactic mastectomies. A retrospective search using specimen type codes was performed in the computerized histopathology archive from April 2007 to April 2016. The pathology results of 505 patients were analyzed (782 specimens). A total of 267 patients underwent simple reduction mammoplasties (10 unilateral), 20 had bilateral prophylactic mastectomies and 218 undertook contralateral symmetrizing or prophylactic mastectomy surgery following a history of breast cancer. Overall, normal (unremarkable) breast tissue was found in 42.6% of patients (n = 215), benign tissue (nonproliferative/proliferative disease without atypia) in 51.1% (n = 258), significant disease (LCIS/proliferative disease with atypia) in 5.5% (n = 28), and malignant disease (invasive/ductal carcinoma in situ) in 0.8% (n = 4). The incidence of significant breast pathology was statistically higher (P value < .0001) in prophylactic mastectomies (12.4%) compared to reduction mammoplasties (2.3%). There was however no significant increase in the incidence of malignancy between prophylactic mastectomies (1.2%) and reduction mammoplasties (0.6%). Even though the clear majority of resected tissue in reduction mammoplasties and prophylactic mastectomies is benign, our findings support the continued need for histological examination of these specimens for occult carcinoma and precursor lesions.

Breast lesions in reduction mammaplasty specimens: a histopathological pattern in 534 patients

BACKGROUND

The prevalence of breast lesions (benign, precancerous and cancer lesions) in reduction mammaplasty (RM) specimens has rarely been reported in Europe and never in the Swiss population.

METHODS

Personal and histopathological data from 534 female patients who underwent RM were reviewed.

RESULTS

Benign and/or malignant lesions were detected in 76.2% of all patients. Benign breast lesions associated with an increased risk of developing breast cancer represented 2.8% of all lesions. Breast cancer in situ was identified in 5 (0.9%) patients. Patient age and previous history of breast cancer were risk factors for incidental breast cancer.

CONCLUSION

The rate of incidental carcinoma in situ was higher for patients with breast cancer history. Probably due to preoperative breast cancer investigation, no occult invasive breast cancer was found in reduction mammary specimens. Therefore before RM, breast cancer evaluation should be considered for all patients, especially for those with breast cancer risk factors (e.g., patient age, personal history of breast cancer).

Should we be analysing breast reduction specimens? A systematic analysis of over 1,000 consecutive cases

BACKGROUND

Reduction mammoplasty (RM) continues to be popular. The reported incidence of occult breast carcinoma in these specimens varies between 0.05 and 1.8 %. Literature review reveals a wide discrepancy in study methodology, outcome measures, and even what is constituted as a "significant" result. We set out to identify RM patients at increased risk of occult significant pathological findings to engender a systematic improvement in efficiency of those specimens sent for histopathological examination.

METHODS

A single-centre retrospective study of the pathology results for 1,388 consecutive RM patients was undertaken. Patients were divided into three groups according to indication for surgery: group 1, macromastia; group 2, developmental asymmetry; and group 3, symmetrising surgery after breast cancer reconstructive surgery.

RESULTS

Nine cases of occult carcinoma were found among the 1,388 women (0.65 %), all in patients over 35 years of age. Forty percent of all patients were under 35 years old. Histopathological analysis of 59 % of patients revealed nonsignificant findings. Patients with a breast cancer history were 4.3 times more likely to have occult breast cancer. Patients under 30 years of age had a significantly higher chance of nonsignificant findings than those over 30 (relative risk = 2.5).

CONCLUSIONS

Although the overall incidence of occult breast cancer in reduction mammaplasty patients remains low, specific subgroups with a higher risk are identified. It is recommended that histological analysis of specimens should be restricted to high-risk patients and those over 30 years of age as significant pathology is uncommon in younger patients. These results will promote health-care-related economic benefits and a reduction of the burden placed on histopathology departments.

Adaptation of the Hall-Findlay technique for simultaneous contralateral reduction in delayed breast reconstruction with extended latissimus dorsi flap

In the past we have validated Hall-Findlay technique of breast reduction with our independent results. The technique combines the safety of the superomedial pedicle with advantages of a vertical scar in a quick but safe manner ensuring adequate resection and sound healing with less scars and faster recovery for the patient. We now report our experience of using an adaptation of the same in simultaneous contralateral reduction in delayed breast reconstruction with extended latissimus dorsi flap.

METHOD

Thirty consecutive patients underwent simultaneous contralateral balancing reduction. The modifications consisted of wider upper pole reduction with smaller, thinner pedicle reducing the projection.

RESULTS

All patients had an uneventful recovery with no haematoma, infection or seroma. Two patients (6.66%) wished further reduction and one (3.33%) required dog-ear revision.

CONCLUSION

The modifications allow the reduction of the contralateral breast with a lower projection to match the extended latissimus dorsi (ELD) flap reconstruction. We have found the modified technique to be reliable and versatile with a shorter operative and recovery time adding minimal morbidity of simultaneous contralateral reduction and effectively reducing the need of a delayed balancing reduction.

[Discovered of breast cancer in adolescent during the plastic surgery: a case report]

Authors report the case of a ductal carcinoma diagnosed after a reduction mammaplasty in a 16 years old female. The pre-operative mammography was normal. The histologic diagnosis was made on the specimen. The specificity and efficiency of pre-operative radiology are discussed in plastic surgery in young patients.

Breast reduction surgery in the UK and Ireland - current trends

INTRODUCTION

This paper reviews the current status of bilateral breast reduction surgery in the UK and Ireland. It examines the pre-operative, operative and postoperative management of women.

PATIENTS AND METHODS

A questionnaire established information about surgeons' experience, bilateral breast reduction work-load, pre-operative assessment, selection criteria, issues of operative technique and postoperative management. This was sent to 230 consultant plastic surgeons working in the NHS in the UK and Ireland.

RESULTS

There was a 61% response rate. Of respondent surgeons, 82% always perform pre-operative photography, 71% never do a mammogram even in patients above the age of 50 years. Body mass index (BMI) is the most commonly used criteria for patient selection (60%). Two-thirds of the surgeons use an inferior pedicle technique and 75% of surgeons work in health authorities that restrict breast reduction surgery.

CONCLUSIONS

There was significant variation in practice among surgeons performing bilateral breast reduction. This may reflect a lack of evidence base for practise. Published literature focuses almost exclusively on the description of different techniques. Further work is required to evaluate the role of pre-operative mammography, specimen mammography, antibiotics and selection criteria for surgery.

Cancer du sein diagnostiqué par la réduction mammaire. Étude rétrospective sur une période de trois ans

In the wake of three consecutive cases of microscopical examination of resection specimens following breast reduction revealing an adenocarcinoma, we wanted to point out the interest of a complete preoperative senological examination including mammography and postoperative anatomopathological examination. A retrospective study concerning 837 patients over a three-year period was conducted. We found seven patients (0.83%) with malignant breast cancer diagnosed on anatomopathological examination, which is comparable to the incidence found in literature. Of these seven cases there were four ductal adenocarcinomas (0.47%), all of them in situ (DCIS), and three lobular adenocarcinomas (0.36%) of which one invasive (ILA), one in situ (LCIS) and one mixed. The majority was aggressive, multifocal and bilateral. Treatment consisted of mastectomy with or without adjuvant therapy with curative intent in five out of seven cases, and this within two months after a esthetic surgery. In our opinion this shows that breast reduction can help in tracking down breast cancer and underlines the need for systematic and meticulous microscopic examination of resection specimens after breast reduction.

Occult breast carcinoma in reduction mammaplasty specimens: 14-year experience

Reduction mammaplasty is commonly performed for bilateral macromastia, congenital asymmetry, or as a contralateral symmetry procedure in breast reconstruction following mastectomy for cancer. Occult carcinoma has been detected in 0.06 percent to 0.4 percent of breast reduction specimens. The purpose of this study was to examine the incidence of breast cancer in breast reductions performed in one institution over a 14-year period. The authors reviewed their experience with 800 reduction mammaplasties performed between 1988 and 2001. Six cancers were detected (0.8 percent). Of these cancers, three were invasive (0.4 percent) and three were ductal carcinoma in situ (0.4 percent). Stratified by indication for surgery, there was a trend toward higher detection rates in the reconstruction group (1.2 percent) compared with the macromastia (0.7 percent) or congenital asymmetry (0 percent) groups. Mammography was performed preoperatively in these patients and all results were negative for masses or suspicious microcalcification. Pathological diagnosis was guided by gross specimen evaluation in two patients and specimen radiography in one patient. Reduction mammaplasty has a small but definite risk of finding cancer in the resection specimen.

Breast Reduction Surgery and Breast Cancer Risk: Does Reduction Mammaplasty Have a Role in Primary Prevention Strategies for Women at High Risk of Breast Cancer?

Prophylactic bilateral mastectomy has been demonstrated to reduce breast cancer incidence in women with a high inherited susceptibility to breast cancer. For the majority of high-risk women, however, bilateral prophylactic mastectomy is not an acceptable option for primary prevention of breast cancer. Several epidemiological follow-up studies have indicated that there may be a substantial reduction in breast cancer risk among women who have undergone breast reduction surgery. The authors reviewed the evidence from these studies, with emphasis on the problems inherent in interpreting the results of nonexperimental studies of elective medical procedures. Although such observational studies cannot demonstrate definitively that reduction mammaplasty reduces the risk of breast cancer, the evidence from these studies is sufficiently strong to warrant the evaluation of breast reduction surgery as an option for primary prevention in clinical studies of women at increased risk of breast cancer. The availability of a more acceptable surgical option for primary prevention of breast cancer could increase the number of women willing to choose risk reduction surgery and thus may result in an overall reduction in breast cancer mortality among high-risk women.

Breast reconstruction

This article reviews the most common procedures utilized by plastic surgeons for breast reconstruction. It discusses the different types of autologous reconstruction and modifications of each. When autologous tissue is not an option, reconstruction using an implant is explored. The other breast may require surgery in order to gain symmetry. Surgical options for the opposite breast include breast augmentation, mastopexy, or breast reduction.

Surgery in breast cancer

This year (1999) has been filled with new information on the prevention of breast cancer and new literature trying to address some of the long-term adverse consequences of our surgical therapies. As the complexities of our therapies continue to increase at exponential rates, we now also have the ability to more accurately predict the consequences of both our therapeutic actions and our failure to act. Nowhere is this more evident than in the literature devoted to long-term consequences of treatment for breast cancer. As we are more successful in achieving our goals of increased survival from this dreaded disease, the future needs of these long-term survivors must play an ever-increasing role in our current management. Advances reported this year are laying down a new basis for efforts to improve the quality of life for breast cancer survivors.
