Despite Equivalent Outcomes, Men Receive Neoadjuvant Chemotherapy Less Often Than Women for Lymph Node-Positive Breast Cancer

Clinicopathological Features and Treatment Outcomes of Male Breast Cancer in Pakistani Population: A 10-Year Retrospective Cross-Sectional Study

Background

Male breast cancer (MBC) accounts for 1% of global breast cancer cases. On account of its rarity, very few prospective clinical trials have been carried out on MBC. Pakistan has the highest incidence of breast cancer in Asia, but very limited data are available on MBC.

Objectives

The objective is to determine the clinicopathological characteristics and treatment patterns of MBC in Pakistani population.

Design

This is a retrospective cross-sectional study.

Methods

A retrospective cross-sectional study carried out using the cancer database of Shaukat Khanum Memorial Cancer Hospital & Research Center. Men with a histologically proven breast cancer, stage 0 to III disease and requiring surgical intervention were included. The Kaplan-Meier curve and log-rank test were used for survival analysis.

Results

Sixty-eight patients with MBC were included with a median age at diagnosis of 55 years. Most patients were stage II (47.1%). Invasive ductal carcinoma (IDC) was the commonest type (89.7%). Estrogen receptor (ER), progesterone receptor (PR), and Her-2 receptor positivity were 92.6%, 86.8%, and 32.4%, respectively. Mastectomy was performed in 95.6% of the cases. Neoadjuvant and adjuvant chemotherapy was administered in 25 (36.8%) and 26 (38.2%) patients, respectively. Fifty-five (80.9%) patients received adjuvant radiotherapy. Most of the patients (89.7%) received tamoxifen. The 5-year overall and disease-free survival was 88.2% and 80.9%, respectively. Patients receiving neoadjuvant chemotherapy had a better overall and disease-free survival (P = .025).

Conclusions

Male breast cancer occurs at a relatively earlier age in Pakistani population as compared with Western men. Mastectomy is the preferred surgical option for MBC on account of the advanced disease and delayed presentation. Neoadjuvant chemotherapy has a statistically significant effect on overall and disease-free survival, but in spite of these benefits, it remains underutilized.

Male Breast Cancer: a Review on Diagnosis, Treatment, and Survivorship

PURPOSE OF REVIEW

Male breast cancer is a relatively uncommon and rare disease that is often managed based on evidence adopted from trials pertaining to female breast cancer due to low accrual rates or exclusion of males. This is despite the known differences in the biology and epidemiology of this condition. This review provides an update regarding the management and surveillance of male breast cancer.

RECENT FINDINGS

Men with breast cancer tend to undergo more extensive surgery in the breast and axilla. The outcomes of male breast cancer compared to a similar subtype of female breast cancer appear worse when matched for stage. Systemic therapies remain predominantly based on recommendations for female breast cancer, although tamoxifen is the more optimal endocrine therapy for men than women. Surveillance with mammograms is recommended for patients harboring a breast cancer susceptibility gene but is otherwise not advised for men who have undergone a mastectomy. Notably, the role of other imaging modalities, including ultrasound and magnetic resonance imaging, is minimal. Although the focus on survivorship care among men is low, it is abundantly clear that this is a stigmatizing diagnosis for men, and they suffer from long-term physical and psychological sequelae following a diagnosis and treatment of breast cancer. In summary, providing more gender-inclusive care and advocating for increased representation of men in prospective breast cancer studies and clinical trials may help improve outcomes and provide enhanced support for this population.

Clinical Effect of Laparoscopic Radical Surgery Combined with Neoadjuvant Chemotherapy in Treating Cervical Cancer and Its Influence on Postoperative Complications and Adverse Reaction Rates

Background. Cervical cancer, the only gynecological malignancy for which a clear pathogeny has been established, has an incidence rate only second to breast cancer. Objective. In our study, we aim to investigate the clinical effect of laparoscopic radical surgery combined with neoadjuvant chemotherapy in treating cervical cancer and its influence on postoperative complications and adverse reaction rates. Methods. Cervical cancer patients admitted to our hospital from August 2018 to May 2020 were retrospectively analyzed as the research object and divided into the control group and the experimental group by the draw method, with 50 cases in each group. The laparoscopic radical surgery was performed on the control group, and the laparoscopic radical surgery combined with neoadjuvant chemotherapy was performed on the experimental group to compare their effective rates, adverse reaction rates, postoperative complication rates, expression levels of serum tumor necrosis factor-α (TNF-α) and soluble interleukin-2 receptor (SIL-2R) inside the body before surgery and at one week after surgery, quality of life (QLI) scores, and Mental Status Scale in Nonpsychiatric Settings (MSSNS) scores. Results. Compared with the control group, the experimental group obtained significantly higher effective rate and QLI scores ( $P$  < 0.05) and significantly lower adverse reaction rates, postoperative complication rates, expression levels of serum TNF-α and SIL-2R inside the body at one week after surgery, and MSSNS scores ( $P$  < 0.05), with statistical differences; before surgery, the TNF-α and SIL-2R expression levels of the two groups were not significantly different ( $P$  > 0.05), but the levels at one week after surgery were significantly lower than those before, indicating statistical significance ( $P$  < 0.05). Conclusion. The clinical effect of laparoscopic radical surgery combined with neoadjuvant chemotherapy can obviously improve the effective rate of cervical cancer patients and lower the incidence rates of postoperative complications and adverse reactions.
