Gynecomastia Due to Hormone Therapy for Advanced Prostate Cancer: A Report of Ten Surgically Treated Cases and a Review of Treatment Options

Complications and Outcomes After Gynecomastia Surgery: Analysis of 204 Pediatric and 1583 Adult Cases from a National Multi-center Database

BACKGROUND

Gynecomastia is a common disease that is prevalent across all age groups of boys and men. Although benign in nature, it can lead to psychological and social distress, prompting affected patients to seek medical attention. Management strategies include observation and drug therapy, yet surgical procedures remain the hallmark of treatment. The goal of this study was to analyze patient demographics, outcomes, and complication rates of gynecomastia surgery in a large multi-institutional cohort.

METHODS

We performed a retrospective analysis of the American College of Surgeons National Surgical Quality Improvement Program adult and pediatric databases to produce two cohorts that underwent gynecomastia surgical repair. The two populations were compared for comorbidities, perioperative details, and complication rates. Multivariate analyses helped detect risk factors associated with adverse events.

RESULTS

A total of 204 pediatric and 1583 adult male patients were identified in our analysis. Mean ages were 15.8 and 39.6 years, respectively. A BMI of 28.2 in the latter cohort revealed an overweight adult population. Preoperative comorbidities (0.0-4.9% in children, 0.0-6.4% in adults) and American Society of Anesthesiologists scores (ASA 1 + 2: 98.5 and 82.7%) symbolized a healthy population. Procedures were subsequently performed mostly as outpatient (84.3 and 93.9%) and with short hospitalization durations (0.27 and 0.06 days). Our results demonstrated low surgical (3.9 and 1.9%) and medical (0.0 and 0.3%) complications within the standardized 30-day postoperative period. Children and adolescents, however, required double mean operative times compared to adults (111.3 vs 56.7 min).

CONCLUSION

Operative gynecomastia treatment remains a safe treatment modality across all age groups. Patients with known preoperative medical or surgical comorbidities necessitate more extensive perioperative assessment and monitoring.

Advances and Prospects in Cancer Immunotherapy

Cancer immunotherapy is a promising and effective treatment modality for patients with cancers. Cytokine, anticytokine, and antibody therapies appear to be effective in treating various forms of cancer. The human papillomavirus vaccine is protective for cervical cancer, and this discovery has paved the way to the development of cancer vaccines for other forms of virus-associated cancers such as liver cancer and Merkel cell carcinoma. Clinical trials have demonstrated that adoptive cell therapy using tumor-infiltrating lymphocytes can induce tumor regression in approximately 75% of metastatic melanoma patients, suggesting the possibility of using similar technique to effectively treat breast, lung, and renal cancers in the near future. Besides, genetically engineered T cells transduced with genes encoding specific T cell receptors and chimeric antigen receptors have been shown effective in the treatment of cancer patients. These studies suggest that combination therapies are superior choices in cancer immunotherapy for patients.

Low rate of clinician-scored gynecomastia induced by 6 months of combined androgen blockade in a randomized trial: Implications for prophylactic breast irradiation

PURPOSE

To determine the incidence and predictors of clinician-scored gynecomastia induced by 6 months of combined androgen blockade (CAB) in a randomized trial.

METHODS

We studied 94 men with intermediate or high-risk prostate cancer randomized to radiation plus 6 months of neoadjuvant CAB consisting of a gonadotropin-releasing hormone agonist and antiandrogen (flutamide). Patients were assessed for breast symptoms monthly as per protocol. Patients reporting breast tenderness or enlargement were then examined shirtless.

RESULTS

Median age at entry was 72.1 years. While 52 patients (55.3%) reported either breast tenderness or enlargement, only 9 patients (9.6%) were scored as having gynecomastia when examined shirtless by a single clinician. Four patients received radiation for self-reported breast tenderness or enlargement without clinician-scored gynecomastia. If these 4 had not been radiated, the total incidence of clinician-scored gynecomastia may have been as high as 13 of 94 (13.8%). No patient variable, such as age, body-mass index, and Adult Comorbidity Evaluation-27 score, or discontinuation of the antiandrogen, was associated with the development of gynecomastia.

CONCLUSIONS

While many patients self-reported breast tenderness or enlargement with short-course CAB, the incidence of breast enlargement noticeable to an examiner when the patient was shirtless was less than 15%, which is much lower than the 60% to 80% rates typically reported with antiandrogen monotherapy. Given that the long-term risks of prophylactic breast irradiation are not well characterized, these data suggest that prophylactic breast irradiation may not be as necessary in men receiving short-course CAB.

Androgen deprivation therapy in prostate cancer: anticipated side-effects and their management

PURPOSE OF REVIEW

In men with metastatic or recurrent prostate cancer, androgen deprivation therapy (ADT) is the standard of care. Although effective in cancer control, ADT is associated with multiple adverse effects of which physicians and patients should be aware herein we review these side-effects and their potential management.

RECENT FINDINGS

ADT reduces serum levels of testosterone and estrogen, resulting in changes in body composition, increased fracture risk, development of insulin resistance, and an unfavorable lipid profile. A number of studies have investigated the association of ADT with cardiovascular mortality; however, it is unclear whether such an association exists. Recently, two separate clinical trials have found that denosumab, a monoclonal antibody, and toremifene citrate, a selective estrogen receptor modulator, could be used to reduce the incidence of fracture in men on ADT.

SUMMARY

By providing clinicians with a greater awareness of the literature on ADT, we may minimize the physical and psychological impact of its side-effects. Physicians should be aware of a recent statement by a multilateral advisory panel, stating that there is no indication for a cardiovascular evaluation before starting ADT. Finally, physicians should be informed of recent developments in the prevention of vertebral fractures in men on ADT.

Management of gynaecomastia: an update

Gynaecomastia, a benign enlargement of the male breast as a result of proliferation of the glandular component, is common, being present in 30-50% of healthy men. It may be an incidental finding, an acute unilateral or bilateral tender breast enlargement or a progressive painless enlargement of the male breast. A general medical history and careful physical examination, looking for features suggestive of breast cancer, often suffice for evaluation in patients without symptoms or those with incidentally discovered breast enlargement. If the gynaecomastia is of recent onset, a more detailed evaluation, including selected laboratory tests to search for an underlying cause is necessary. Treatment depends on the cause: an offending drug may need to be withdrawn or alternatively radiation, surgery and/or medical therapy may be necessary. The use of a combination of surgical excision and liposuction through a periareolar incision represents the surgical approach of choice.

Correction of gynecomastia through a single puncture incision

In men, the development of feminized breasts may cause significant emotional distress and embarrassment, particularly in young men and adolescents. Unfortunately, gynecomastia responds poorly to diet and exercise, and conventional corrective surgery may produce large stigmatizing areolar or chest scars and a flattened or concave chest. In 2004, board-certified plastic surgeons performed 16,275 corrective procedures, and in 2005 there was a 17% increase, according to The American Society of Plastic Surgeons (ASPS) procedural statistics. This report describes a surgical approach for removal of both glandular and adipose tissue using a small 3-mm areolar stab wound incision and a piecemeal glandular resection to correct gynecomastia with minimal and imperceptible external scarring. Pectoral etching of the chest and suction lipectomy are performed simultaneously to enhance and define the thoracic musculature and further virilize the upper thorax. Excellent results have been obtained with minimal complications. The authors present their experience with more than 200 consecutive cases over the past 4 years. They are very optimistic with these results because they have obtained a high degree of patient satisfaction.

Prostate cancer treatment and quality of life

Prostate cancer is detected today at earlier stages and in younger men than ever before. A lot of men are asymptomatic and also physically and sexually active at diagnosis, and most of them are being treated by curative procedures. These trends have led to increasing numbers of patients undergoing disease management for longer periods of time. For many patients quality of life (QoL) may be just as important as survival. Thus, QoL considerations may well be the critical factor in medical decision-making for most of them. Widespread interest in studying patient-centred outcomes has led to the development of methods for health-related QoL measurements. In fact, many questionnaires have been introduced in clinical practice to assess the impact of QoL in patients (SF-36, CARES, FACT, EORTC QLQ-C30, GRISS, UCLA PCI, PCOS). Herein we evaluate the impact of QoL on patients affected by prostate cancer and treated with watchful waiting, radical prostatectomy, radiotherapy and hormonal therapy; we have also considered the role of supportive care, including the administration of analgesics, antidepressants, corticosteroids, bisphosphonates, antiemetics and stool softeners, together with psychological support. The ultimate goal of QoL research should strongly improve medical care and concretely assist patients and physicians in treatment decision-making.

The role of radiation therapy in benign diseases

Although adequate prospective data are lacking, radiation therapy seems to be effective for many benign diseases and remains one of the treatment modalities in the armamentarium of medical professionals. Just as medication has potential adverse effects, and surgery has attendant morbidity, irradiation sometimes can be associated with acute and chronic sequelae. In selecting the mode of treatment, most radiation oncologists consider the particular problem to be addressed and the goal of therapy in the individual patient. It is the careful and judicial use of any therapy that identifies the professional. With an understanding of the current clinical data, treatment techniques, cost, and potential detriment, the goal is to provide long-term control of the disease while minimizing unnecessary treatment and potential risks of side effects. The art lies in balancing benefits against risks.

Gynecomastia in patients with prostate cancer: update on treatment options

Non-steroidal antiandrogen monotherapy offers potential quality of life benefits over other treatment modalities in patients with prostate cancer. Nevertheless, gynecomastia and breast pain still represent the most bothersome side effects during this treatment. In this update article, recent advances in the management options for gynecomastia/breast pain caused by hormonal manipulation are reviewed and critically analyzed.

Management of gynaecomastia in patients with prostate cancer: a systematic review

Patients with prostate cancer are increasingly being offered treatment with non-steroidal antiandrogen monotherapy, which offers potential quality-of-life benefits compared with other treatment. Non-steroidal antiandrogens directly antagonise androgen action in breast tissue, and indirectly increase the oestrogen concentration. Thus, the most troublesome side-effects of monotherapy with these drugs are gynaecomastia and breast pain. Patients younger than 60 years of age, who might not have symptoms of prostate cancer, are probably more concerned about their body image and the development of enlarged breasts than are those older than 60 years. Clinicians who seek a treatment for prostate cancer need information on simple and well-tolerated options for the management of gynaecomastia and breast pain. In this review, management options for gynaecomastia caused by hormonal manipulation in patients with prostate cancer are discussed.

Efficacy of tamoxifen and radiotherapy for prevention and treatment of gynaecomastia and breast pain caused by bicalutamide in prostate cancer: a randomised controlled trial

BACKGROUND

Gynaecomastia and breast pain are frequent adverse events with bicalutamide monotherapy, and might cause some patients to withdraw from treatment. We aimed to compare tamoxifen with radiotherapy for prevention and treatment of gynaecomastia, breast pain, or both during bicalutamide monotherapy for prostate cancer.

METHODS

51 patients were randomly assigned to 150 mg bicalutamide per day, 50 patients to 150 mg bicalutamide per day and to 10 mg tamoxifen per day for 24 weeks, and 50 patients to 150 mg bicalutamide per day and radiotherapy (one 12-Gy fraction on the day of starting bicalutamide). 35 of the 51 patients allocated bicalutamide alone developed gynaecomastia or breast pain and were subsequently randomly allocated to tamoxifen (n=17) or radiotherapy (n=18) soon after symptoms started (median 180 days, range 160-195). Gynaecomastia and breast pain were assessed once a month. Severity of gynaecomastia was scored on the basis of the largest diameter. Breast pain was scored as none, mild, moderate, or severe. The primary outcome was frequency of gynaecomastia or breast pain; secondary outcomes were safety and tolerability, relapse-free survival, as assessed by concentration of prostate specific antigen, and quality of life. Analyses were by intention to treat.

RESULTS

35 of 51 patients assigned bicalutamide alone developed gynaecomastia, compared with four of 50 assigned bicalutamide and tamoxifen (odds ratio [OR] 0.1 [95% CI 0.08-0.12], p=0.0009), and with 17 of 50 assigned bicalutamide and radiotherapy (0.51 [0.47-0.54], p=0.008). Breast pain was seen in 29 of 51 patients allocated bicalutamide alone, compared with three allocated bicalutamide and tamoxifen (0.1 [0.07-0.11], p=0.009), and with 15 allocated bicalutamide and radiotherapy (0.43 [0.40-0.45], p=0.02) In 35 patients assigned bicalutamide alone who subsequently developed gynaecomastia, breast pain, or both, tamoxifen significantly reduced the frequency of gynaecomastia (0.2 [0.18-0.22], p=0.02).

INTERPRETATION

Antioestrogen treatment with tamoxifen could help patients with prostate cancer to tolerate the hypergonadotropic effects of bicalutamide monotherapy.
