Breast lesions excised via vacuum-assisted system: could we get any clues for B3 lesions before excision biopsy?

BACKGROUND: The purpose of this study was to determine the validity of the ultrasound features as well as patient characteristics assigned to B3 (uncertain malignant potential) breast lesions before vacuum-assisted excision biopsy (VAEB). METHODS: This study population consisted of 2245 women with breast-nodular abnormalities, which were conducted ultrasound-guided VAEB (US-VAEB). Patient's clinical and anamnestic data and lesion-related ultrasonic feature variables of B3 captured before US-VAEB were compared with those of benign or malignant cases, using histopathological results as a benchmark. RESULTS: The proportions of benign, B3 and malignant breast lesions diagnosed post-US-VAEB were 88.5, 8.2 and 3.4% respectively. B3 high frequent occurred in BI-RADS-US grade 3 (7.7%), grade 4a (11.0%) and grade 4b (9.1%). The overall malignancy underestimation rate of B3 was 4.4% (8/183). Malignant lesions were found mostly in the range of BI-RADS grade 4b (27.3%), grade 4c (33.3%) and grade 5 (100%). Multivariate binary logistic regression analyses (B3 vs benign) showed that non-menopausal patients (95% CI 1.628-8.616, P = 0.002), single (95% CI 1.370-2.650, P = 0.000) or vascularity (95% CI 1.745-4.150, P = 0.000) nodules in ultrasonic features were significant risk factors for B3 occurrences. In addition, patients elder than 50 years (95% CI 3.178-19.816, P = 0.000), unclear margin (95% CI 3.571-14.119, P = 0.000) or suspicious calcification (95% CI 4.010-30.733, P = 0.000) lesions were significantly associated with higher risks of malignant potentials for B3 cases (malignant vs B3). CONCLUSION: The results of this study indicate that ultrasound findings and patients' characteristics might provide valuable information for distinguishing B3 lesions from benign breast abnormalities before VAEB, and help to reduce malignancy underestimation of B3.

Gasless endoscopic transaxillary subcutaneous mastectomy and immediate reconstruction with implants (GETSMIRI) for breast cancer: Lei's five-step method.

Background: Endoscopic nipple-sparing mastectomy (E-NSM) is a promising procedure in the treatment of breast cancer, but the limitations of endoscopic tools and intrinsic technical complexity of the technique hinder its applicability. Here, we introduce a novel surgery, gasless endoscopic transaxillary subcutaneous mastectomy and immediate reconstruction with implants (GETSMIRI), for breast cancer. and early effects. Methods: A retrospective analysis of the clinical data of 11 female patients, aged 50 (27-78) years, admitted to our hospital from January to December 2022, who underwent gasless endoscopic transaxillary subcutaneous mastectomy and immediate reconstruction with implants (GETSMIRI), was conducted. This study was designed to assess patient satisfaction before and after breast reconstruction, early complications, and breast function. Results: The tumors were all solitary, with a mean maximum diameter of 1.0 (0-2.0) cm and a mean distance of 2.3 (2-4) cm from the nipple, the mean intraoperative bleeding volume was 47.5 mL, and the mean hospital stay was 1.5 d. Postoperatively, 1 patient developed depigmentation of the nipple due to mild ischemia. There were no incisional complications, subcutaneous emphysema, infection, areola necrosis, skin flap necrosis, or removal of the prosthesis and/or patch. No tumor recurrence or metastasis was observed during the follow-up period. The difference between breast satisfaction and psychosocial health scores was not statistically significant (P = 0.680; P = 0.612). Conclusion: GETSMIRI, immediate implantable breast reconstruction, is less invasive than other such procedures, and short-term follow-up results show good postoperative satisfaction, making it an alternative surgical method.

Thyrotropin suppression therapy using levothyroxine does not negatively affect breast cancer prognosis.

INTRODUCTION: Breast cancer (BC) and thyroid dysfunction are common in females, yet the relationship between thyroid hormone and BC is unclear. To search for the connection between thyrotropin and BC, we contradistinguished BC patients with or without synchronous second primary thyroid cancer (TC) with surgery using data from the Surveillance, Epidemiology, and End Results (SEER) database. Theoretically, according to the ATA (American Thyroid Association) guidelines, all TC patients were treated with thyrotropin suppressive therapy only from 2010 to 2015. MATERIALS AND METHODS: Data from BC patients with a synchronous second TC with surgery (BC2TC) and only BC patients (1BC) during 2010-2015 were extracted from the SEER database. Differences in the clinicopathological characteristics between BC2TC and 1BC patients were analyzed by chi-square tests. Comparisons of the disease-specific survival (DSS) and overall survival (OS) curves between these two groups were performed with the log-rank (Mantel-Cox) test. RESULTS: Within this dataset, we identified 134 BC2TC patients during the period from 2010 to 2015. Significant differences between the BC2TC and 1BC groups were found only for different ages and TNM (tumor-node-metastasis status) stages. There were no significant differences in DSS between the two cohorts (P = 0.060). The same tendencies in OS or DSS were observed for the different age groups and different TNM groups, even the stage I, N0 (without metastases to lymph nodes), and ER (+) (estrogen receptor (ER)-positive) groups. CONCLUSIONS: There were no remarkable differences in survival between the BC2TC and 1BC groups, and thyrotropin suppression therapy using levothyroxine did not negatively affect BC prognosis.
