The Predictive Factors of Combined Implant Application for Breast Cancer Patients Receiving Immediate Breast Reconstruction with a Pedicled Omental Flap. Ann Surg Oncol 2024:10.1245/s10434-024-15882-w. [PMID: 39048897 DOI: 10.1245/s10434-024-15882-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2023] [Accepted: 07/08/2024] [Indexed: 07/27/2024]
Abstract
BACKGROUND Whether a laparoscopically harvested omental flap is adequate for total breast reconstruction could not be determined preoperativaly due to lack of reliable assessment methods. This study aimed to establish a statistical model to predict the probability of omental flap insufficiency. METHODS In this study, 200 female patients with breast cancer receiving immediate breast reconstruction with pure pedicled omental flaps or pedicled omental flaps combined with implants after nipple-areolar complex-sparing mastectomy were divided into two groups depending on whether implants were needed or not. The clinical characteristics of these two groups were compared. Correlation of body mass index (BMI) and omental volume was analyzed. Binary logistic regression was performed to predict the probability of implant requirement based on clinical parameters, showing significant differences between the two groups. RESULTS The patients who needed implants in adjunct treatment were younger. In addition, they had larger breast specimens and smaller omental volumes than the others whose omental flaps were sufficient for total breast reconstruction. Body mass index and omental volume showed a moderately positive correlation. Age, specimen volume, and BMI all were entered into the logistic regression equation. For the patients with a BMI lower than 24.0 kg/m2, the probability of requiring implants was 5.467 times that of comparable patients with a BMI of 24.0 kg/m2 or higher. At the cutoff of 0.61, the regression equation yielded a sensitivity of 84.2% and a specificity of 72.1% in recognizing subjects with the necessity of implant application. CONCLUSION The combination of BMI, age, and volume of breast specimen could predict with high accuracy whether implants are required for breast cancer patients receiving pedicled omental flap-based breast reconstruction.

Three-dimensional visual technique based on CT lymphography data combined with methylene blue in endoscopic sentinel lymph node biopsy for breast cancer. Eur J Med Res 2022; 27:274. [PMID: 36464689 PMCID: PMC9719621 DOI: 10.1186/s40001-022-00909-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/17/2021] [Accepted: 11/21/2022] [Indexed: 12/07/2022] Open
Abstract
BACKGROUND The combined application of blue dye and radioisotopes is currently the primary mapping technique used for sentinel lymph node biopsy (SLNB) in breast cancer patients. However, radiocolloid techniques have not been widely adopted, especially in developing countries, given the strict restrictions on radioactive materials. Consequently, we carried out a retrospective study to evaluate the feasibility and accuracy of three-dimensional visualization technique (3DVT) based on computed tomography-lymphography (CT-LG) in endoscopic sentinel lymph node biopsy (ESLNB) for breast cancer. METHODS From September 2018 to June 2020, 389 patients who underwent surgical treatment of breast cancer in our department were included in this study. The CT-LG data of these patients were reconstructed into digital 3D models and imported into Smart Vision Works V1.0 to locate the sentinel lymph node (SLN) and for visual simulation surgery. ESLNB and endoscopic axillary lymph node dissection were carried out based on this new technique; the accuracy and clinical value of 3DVT in ESLNB were analyzed. RESULTS The reconstructed 3D models clearly displayed all the structures of breast and axilla, which favors the intraoperative detection of SLNs. The identification rate of biopsied SLNs was 100% (389/389). The accuracy, sensitivity, and false-negative rate were 93.83% (365/389), 93.43% (128/137), and 6.57% (9/137), respectively. Upper limb lymphedema occurred in one patient 3 months after surgery during the 12-month follow-up period. CONCLUSIONS Our 3DVT based on CT-LG data combined with methylene blue in ESLNB ensures a high identification rate of SLNs with low false-negative rates. It, therefore, has the potential to serve as a new method for SLN biopsy in breast cancer cases.

Verification of Volume Similarity Between Unilateral Mammary Gland and Autologous Omentum in Adult Women by Measuring Cylinder Method. Int J Gen Med 2021; 14:9211-9218. [PMID: 34880660 PMCID: PMC8646107 DOI: 10.2147/ijgm.s333578] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/10/2021] [Accepted: 09/30/2021] [Indexed: 11/23/2022] Open
Abstract
Objective To verify the volume similarity between unilateral mammary gland and autologous omentum in adult females. Methods A total of 63 patients diagnosed with stage 0–II breast cancer and partial non-lactating multi-fistula mastitis in the breast surgery department of Inner Mongolia Xing’an League People's Hospital from 2007 to 2020 were enrolled in the study, including 52 cases of stage 0–II breast cancer and 11 cases of non-lactating multi-fistula mastitis. The volume of the resected mammary gland and the omentum were measured by a “soft tissue measuring cylinder” and recorded. The appearance of the reconstructed breast was compared with that of the healthy side. The correlation between unilateral mammary gland volume and autologous omentum volume was analyzed by linear regression. Results Valid data were obtained for 60 cases. Affected breast size, curve, texture, nipple, and inframammary fold after omentum breast reconstruction were similar and symmetrical to those of the unaffected side. Postoperative complications occurred in most patients; the majority of these (76.67%) involved numbness of the nipple, and other complications were few. Patient satisfaction with postoperative appearance, feel, and movement of the breast, as well as total treatment costs, was over 75.0%. Linear regression analysis indicates a linear relationship between subcutaneous gland volume (x) and autologous omentum volume (y): y = 0.9847x - 1.2132, R2 = 0.9742. Conclusion Only when the dissociated pedicled omentum is completely obtained under laparoscopy can the whole subcutaneous residual cavity of the mammary gland be filled to the same volume. This study verifies that the volume of the unilateral mammary gland is similar to that of the autologous omentum in adult females.
