Male breast cancer: Modified radical mastectomy or breast conservation surgery? A case report and review of the literature

The effects of rapid rehabilitation nursing on improving postoperative rehabilitation effect and life quality of early breast cancer patients

This study was intended to determine whether rapid rehabilitation nursing can enhance postoperative rehabilitation and life quality for breast cancer (BC) patients. One hundred seventy-two patients with BC treated in our hospital from March 2020 to September 2022 were included in this retrospective study and divided into the observation group (n = 86) and control group (n = 86) based on the different nursing methods that they received. The control group accepted routine nursing care, and the observation group accepted rapid rehabilitation nursing intervention. The amount of intraoperative blood loss, anesthesia awake time, postoperative drainage tube removal time, postoperative time of getting out of bed, length of hospital stays, incidence of postoperative complications, and postoperative recovery rate of affected limb, Barthel index and quality of life instruments for cancer patients: breast cancer (QLICP-BR) of BC patients were analyzed. The amount of intraoperative bleeding in the observation group was less, and the difference was statistically significant (P < .05). The awake time of anesthesia, the time of pulling out the drainage tube after operation, the time of getting out of bed after operation and the time of hospitalization in the observation group were significant shorter (P < .05). The incidence of postoperative complications in the observation group was notably lower (P < .05). The excellent and good rate of postoperative rehabilitation of the affected limbs in the observation group was notably higher (P < .05). Before nursing, there exhibited no notable difference in the scores of Barthel index (P > .05). After 10 days of nursing, the score of Barthel index in the observation group was notably higher (P < .05). After 10 days of nursing, the QLICP-BR score of the observation group was significant higher (P < .05). Rapid rehabilitation nursing is beneficial to reduce the intraoperative blood loss of BC patients, shorten the recovery time of anesthesia, promote the excellent and good rate of rehabilitation of affected limbs, and improve the quality of life.

Management of Male Patients With Occult Breast Cancer: Analysis of the National Cancer Database

INTRODUCTION

Occult breast cancer (OBC) consists of <0.1% of breast cancer cases in the United States. Male occult breast cancer (mOBC) has not been well-studied outside of case reports, and management is largely based on female OBC (fOBC) studies. We aim to examine the prevalence of mOBC among those in the National Cancer Database with breast cancer and describe treatment modalities received by mOBC compared to fOBC.

METHODS

The National Cancer Database was queried for patients with OBC from 2004 to 2018. Chi-Square test and Fisher's exact tests compared patient, clinical, and facility characteristics by sex. Treatment modalities [systemic therapy, radiation therapy, axillary lymph node dissection, modified radical mastectomy (MRM)] were compared. A subgroup analysis examined pathologic upstaging in patients who underwent MRM.

RESULTS

Of 23,374 male patients with breast cancer, 0.13% were identified to have mOBC [versus 0.09% in fOBC]. cN2/N3 disease was significantly more prevalent in the mOBC cohort (61.3%) than in the fOBC cohort (30.7%, P < 0.001). Receipt of axillary lymph node dissection or MRM was not significantly different by sex. Male OBC (mOBC) patients were less likely to receive trimodality treatment than fOBC patients. In patients who underwent MRM, more mOBC patients [75%] were pathologically upstaged as T+ after mastectomy than fOBC patients [30%, P < 0.001], questioning the adequacy of diagnostic workup for mOBC compared to fOBC.

CONCLUSIONS

This review confirms mOBC as an extremely rare disease. Multimodal treatments have been highly utilized to optimize care in this patient population. Further investigation is warranted to examine the survival benefit of treatment regimens for mOBC.

Postmastectomy Reconstruction in Male Breast Cancer

Introduction

Less than 1% of all breast cancers are diagnosed in males. In females, postmastectomy breast reconstruction is associated with increased patient satisfaction. However, there is a paucity of literature describing reconstructive options for postmastectomy deformity in the male chest. The purpose of this systematic review was to evaluate postmastectomy reconstruction outcomes in males with breast cancer.

Methods

A systematic review was performed in accordance with PRISMA guidelines. Ovid MEDLINE, Embase, Cochrane, and Web of Science were queried for records pertaining to the study question using medical subject heading (MeSH) terms such as "male breast cancer," "mastectomy," and "reconstruction." No limitations were placed on the year of publication, country of origin, or study size. Study characteristics and patient demographics were collected. Primary outcomes of interest included postoperative complications, recurrence rate, and mortality rate.

Results

A total of 11 articles examining 29 male patients with breast cancer who underwent postmastectomy reconstruction were included for analysis. Literature was most commonly available in the form of case reports. The average age was 59.6 +/-11.4 years. Reconstruction methods included fat grafting (n = 1, 3.4%), silicone implants (n = 1, 3.4%), and autologous chest wall reconstruction with local flaps (n = 26, 89.7%). Postoperative complications occurred in two patients (6.8%), including partial nipple necrosis (n = 1) and hypertrophic scarring (n = 1). Of the studies reporting patient satisfaction, all patients were pleased with the aesthetic appearance of their chest.

Conclusion

This systematic review revealed the limited availability of research regarding postmastectomy chest reconstruction in males with breast cancer. Nevertheless, the evidence available suggests that reconstruction can restore a patient's body image and, thus, should be regularly considered and discussed with male patients. Larger studies are warranted to further shed light on this population.

Male Triple-Negative Breast Cancer

Male breast cancer is a rarely encountered disease, when compared with female breast cancer, often detected in more advanced stage at the time of diagnosis, and associated with more lymph node metastasis rates, more estrogen receptors positivity, and less human epidermal growth factor receptor-2 expression (HER-2) rates. Surgical management also shows some difference, where the most common operative technique of male breast cancer patients is mastectomy and/or axillary surgery. Triple-negative breast cancer is less frequent than other subtypes and is associated with poorer prognosis. This is because of its association with higher histopathological grade than that in other types of breast cancer. Only fewer treatment options are available compared to hormone-positive, HER-2 positive breast cancer. We are present a case of 71-year-old gentleman with triple-negative breast cancer.

A Clinicogenetic Prognostic Classifier for Prediction of Recurrence and Survival in Asian Breast Cancer Patients

Background

Several prognostic factors affect the recurrence of breast cancer in patients who undergo mastectomy. Assays of the expression profiles of multiple genes increase the probability of overexpression of certain genes and thus can potentially characterize the risk of metastasis.

Methods

We propose a 20-gene classifier for predicting patients with high/low risk of recurrence within 5 years. Gene expression levels from a quantitative PCR assay were used to screen 473 luminal breast cancer patients treated at Taiwan Hospital (positive for estrogen and progesterone receptors, negative for human epidermal growth factor receptor 2). Gene expression scores, along with clinical information (age, tumor stage, and nodal stage), were evaluated for risk prediction. The classifier could correctly predict patients with and without relapse (logistic regression, P<0.05).

Results

A Cox proportional hazards regression analysis showed that the 20-gene panel was prognostic with hazard ratios of 5.63 (95% confidence interval 2.77-11.5, univariate) and 5.56 (2.62-11.8, multivariate) for the “genetic” model, and of 8.02 (3.52-18.3, univariate) and 19.8 (5.96-65.87, multivariate) for the “clinicogenetic” model during a 5-year follow-up.

Conclusions

The proposed 20-gene classifier can successfully separate the patients into two risk groups, and the two risk group had significantly different relapse rate and prognosis. This 20-gene classifier can provide better estimation of prognosis, which can help physicians to make better personalized treatment plans.

Male occult triple-negative breast cancer

Male breast cancer is a rare but important condition accounting for only 1% of breast cancer worldwide and less than 1% of all male malignancies. Occult male breast cancer is an extremely rare type of male breast cancer that manifests as axillary metastases without an identifiable breast lesion. We report a case of triple-negative occult male breast cancer who underwent modified radical mastectomy.

Survival Comparisons Between Early Male and Female Breast Cancer Patients

We aimed to compare the overall survival (OS) and standardized mortality rate (SMR) of the male breast cancer (MBC) with female breast cancer (FBC) after propensity score matching. Based on the Surveillance, Epidemiology, and End Results (SEER), the early breast cancer patients (T1-2N0-2M0) were extracted from 1998-2007. This study included 1,111 and 2,151 patients with early MBC and FBC, respectively, whose clinicopathological characteristics were well balanced. At a mean follow-up time of 97 months, 10-year OS rate was 58.3% in the MBC group and 68.7% in the FBC (log-rank test, P < 0.001; hazard ratio (HR) = 1.45, 95% confidence interval (CI) = 1.29 to 1.64). Adjusted HR for OS between MBC and FBC were revealed from propensity score matched-multivariable Cox proportional hazards models (HR = 1.53, 95% CI = 1.35 to 1.73). Similar adjusted SMRs between MBC and FBC ((SMR = 1.98, 95% CI = 1.83,2.14) for FBC and (SMR = 2.07, 95% CI = 1.88-2.28) for MBC) were observed. The nomogram was constructed for FBC, and predicted probabilities were generally good (C-index = 0.71), whose area under curve is higher than TNM stage classification (0.74 vs 0.62). OS was significantly decreased among early MBC patients compared with FBC, but similar SMRs and its trends by age groups were observed between MBC and FBC except for young patients.

Drainage after Modified Radical Mastectomy - A Methodological Mini-Review

Breast cancer is a socially relevant group of malignant conditions of the mammary gland, affecting both males and females. Most commonly the surgical approach of choice is a modified radical mastectomy (MRM), due to it allowing for both the removal of the main tumor mass and adjacent glandular tissue, which are suspected of infiltration and multifocality of the process, and a sentinel axillary lymph node removal. Most common post-surgical complications following MRM are the formation of a hematoma, the infection of the surgical wound and the formation of a seroma. These post-surgical complications can, at least in part, be attributed to the drainage of the surgical wound. However, the lack of modern and official guidelines provides an ample scope for innovation, but also leads to a need for a randomized comparison of the results. We compared different approaches to wound drainage after MRM, reviewed based on the armamentarium, number of drains, location, type of drainage system, timing of drain removal and no drainage alternatives. Currently, based on the general results, scientific and comparative discussions, seemingly the most affordable methodology with the best patient outcome, with regards to hospital stay and post-operative complications, is the placement of one medial to lateral (pectoro-axillary) drain with low negative pressure. Ideally, the drain should be removed on the second or third postoperative day or when the amount of drained fluid in the last 24 hours reaches below 50 milliliters.

Innervation of the Male Breast: Psychological and Physiological Consequences

Breasts, including the nipple and areola, have two functions: lactation and as an erogenous area. Male breasts are much less studied that those of women. In men, breasts have only an erotic function. Because there is dense and very well organized innervation of the nipple-areola complex in men, nipple erection occurs frequently and via different mechanisms from penile erection. Although it seems to be less important for men than for women and it is poorly studied, the erotic value of breast stimulation is notable. Consequently, there is a need to include this aspect in sexological and andrological studies and to preserve breasts and their innervation or to reconstruct them in cases of surgical intervention.
