A Systematic Review and Meta-Analysis on the Role of Repeat Breast-Conserving Surgery for the Management of Ipsilateral Breast Cancer Recurrence

Patient Preference for Surgical Methods for Ipsilateral Breast Tumor Recurrence

BACKGROUND

Mastectomy has been the standard surgical treatment for ipsilateral breast tumor recurrence (IBTR). Recently, there has been growing interest in repeat breast-conserving surgery (rBCS) for IBTR among breast surgeons; however, there is currently little information regarding patient preferences for surgical procedure for IBTR. The purpose of this study was to evaluate preference for surgical procedure (mastectomy vs. rBCS) among breast cancer patients who had undergone salvage surgery for IBTR.

METHODS

Overall, 100 breast cancer patients who had undergone salvage surgery for IBTR were asked about their preferred surgical methods for IBTR and the reason. The association of patient preference and the reasons related to various clinical and pathological factors were assessed.

RESULTS

Of the 100 respondents, only 11 patients (11%) preferred rBCS. Patients who had undergone rBCS and radiotherapy for IBTR were significantly more likely to prefer to undergo rBCS than other groups (p = 0.030). The most frequent reason for choosing rBCS was the patient's desire to minimize breast deformity and surgical wounds.

CONCLUSIONS

Our study revealed that there is a low rate of patients who opt to undergo rBCS among patients who had undergone salvage surgery for IBTR. Discrepancies in perceptions regarding the surgical procedure for IBTR between patients and their surgeons may exist.

The Age-Male-Albumin-Bilirubin-Platelets (aMAP) Risk Score Predicts Liver Metastasis Following Surgery for Breast Cancer in Chinese Population: A Retrospective Study

Objective

The current study is conducted to investigate the potential prognostic value of the age-male-albumin-bilirubin-platelets (aMAP) score in breast cancer patients with liver metastasis after surgery.

Methods

This is a retrospective study of 178 breast cancer patients who developed liver metastasis after surgery. These patients were treated and followed up from 2000 to 2018 at our hospital. The aMAP risk score was estimated in accordance with the following formula: . The optimal cutoff value of the aMAP was evaluated via X-tile. Kaplan-Meier, Log-rank and Cox proportional hazards regression models were applied to determine the clinical influence of the aMAP score on the survival outcomes. The nomogram models were established by multivariate analyses. The calibration curves and decision curve analysis were applied to evaluate the estimated performance of the nomogram models.

Results

A total of 178 breast cancer patients were divided into low aMAP score group (<47.6) and high aMAP score group (≥47.6) via X-tile plots. The aMAP score was a potential prognostic factor in multivariate analysis. The median disease free survival (p=0.0013) and overall survival (p=0.0003) in low aMAP score group were longer than in high aMAP score group. The nomograms were constructed to predict the DFS with a C-index of 0.722 (95% CI, 0.673-0.771), and the OS with a C-index of 0.708 (95% CI, 0.661-0.755). The aMAP-based nomograms had good predictive performance.

Conclusion

The aMAP score is a potential prognostic factor in breast cancer with liver metastasis after surgery. The aMAP score-based nomograms were conducive to discriminate patients at high risks of liver metastasis and develop adjuvant treatment and prevention strategies.

Unlocking the Power of the Homing Phenomenon: Why Breast Conserving Surgery Outshines Mastectomy in Overall Survival

Breast cancer stands as the most frequently diagnosed malignancy in women, holding a prominent position among the leading causes of cancer-related fatalities on a global scale. Despite significant advances in treatment modalities, approximately 20% of patients experience relapses after the first 5 years of postdiagnosis surveillance. While initial investigations from the 1970s indicated comparable survival rates between breast-conserving surgery (BCS) coupled with radiation therapy and mastectomy, recent research suggests that, within the context of modern systemic and radiation therapy, BCS followed by radiation may offer an improved overall survival benefit. Nevertheless, extended follow-up studies have unveiled a notable increase in the risk of locoregional recurrence associated with breast conserving therapy in contrast to mastectomy. This article introduces a novel hypothesis rooted in the biological phenomenon of homing to elucidate this intriguing clinical observation. We postulate that a breast homing mechanism of reactivated circulating and disseminated tumor cells mediated by chemotaxis involving at least the CXCR4-SDF-1 axis may provide a biological rationale for this clinical phenomenon.

REPEATED BREAST-CONSERVING SURGERIES AS REFLECTION OF THE EVOLUTION IN BREAST CANCER TREATMENT (CASE REPORT WITH LITERATURE REVIEW)

The clinical case of a patient with multicentric breast cancer who underwent organ-sparing surgery after neoadjuvant chemo-radiation therapy is presented. An ipsilateral cancer recurrence was diagnosed 8 years after the first operation. The repeated organ-sparing surgery (lumpectomy) was done with a good cosmetic result and without disease progression during 1-year follow-up. The literature review shows that neoadjuvant systemic therapy accounting for molecular subtypes of cancer has radically changed breast cancer surgeries. The evolution of surgical approaches in stage I-II breast cancer patients consists in the de-escalation of surgery from mastectomy to organsparing or oncoplastic surgery, minimally directed surgery, and repeated breast-conserving surgery. De-escalation of surgical interventions in the area of the regional lymphatic collector consists in the transition from total axillary lymphatic dissection to sentinel lymph node biopsy or targeted removal of metastatic lymph nodes. The repeated breast-conserving surgery can be safely performed for ipsilateral recurrence in patients with all molecular subtypes of breast cancer.
