Jiang Q, Liao J, Tan J, Hu H. Comparison of minimal access and open breast surgery: a propensity score-matched study on postoperative immune function in breast cancer. World J Surg Oncol 2024; 22:183. [PMID: 39010087 PMCID: PMC11251114 DOI: 10.1186/s12957-024-03447-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/25/2024] [Accepted: 06/16/2024] [Indexed: 07/17/2024] Open
Abstract
BACKGROUND Minimal access breast surgery (MABS) is commonly employed in the management of breast cancer, but there is limited research on the postoperative immune function associated with MABS. OBJECTIVE This study aimed to assess the postoperative immune function in breast patients who underwent MABS or conventional open breast surgery (COBS). METHODS We retrospectively analyzed the medical records of 829 breast cancer patients treated with either MABS or COBS at a single hospital between January 2020 and June 2023. Among them, 116 matched pairs were obtained through 1:1 propensity score matching (PSM). Flow cytometry was used to measure the percentages of CD3+, CD4+, and CD8+ cells, as well as the CD4+/CD8+ ratio, on three different time points: preoperative day 1 (PreD1), postoperative day 1 (PostD1), and postoperative day 7 (PostD7). RESULTS Both the MABS and COBS groups demonstrated a significant reduction in the percentages of CD3+, CD4+, and CD8+ cells, along with the CD4+/CD8+ ratio, from PreD1 to PostD1. Interestingly, the MABS group showed a reversal of these parameters, returning to preoperative levels by PostD7. Conversely, the COBS group showed an increase in these parameters from PostD1 to PostD7, but they still remained significantly lower than preoperative levels at PostD7. CONCLUSION MABS treatment may result in reduced postoperative immune suppression and faster recovery of preoperative immune function compared to COBS in patients.

Sae-Lim C, Lai HW, Lin SL, Huang HI, Chen ST, Chen DR. Is minimal-accessed (endoscopic- or robotic-assisted) nipple-sparing mastectomy contraindicated for large breasts? EUROPEAN JOURNAL OF SURGICAL ONCOLOGY 2024; 50:108030. [PMID: 38402736 DOI: 10.1016/j.ejso.2024.108030] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/22/2023] [Revised: 01/29/2024] [Accepted: 02/13/2024] [Indexed: 02/27/2024]
Abstract
BACKGROUND In the developmental stage of minimal-accessed nipple-sparing mastectomy (MA-NSM), selecting patients with small to medium-sized breasts was common for better cosmetic outcomes and oncological safety. However, the suitability of MA-NSM for large, ptotic breasts remained uncertain. This retrospective study aim to assess MA-NSM outcomes in patients with large breasts. MATERIALS AND METHODS This retrospective study included patients receiving conventional NSM (C-NSM) and MA-NSM from January 2011 to September 2022, at a single institution. We analyzed perioperative parameters and clinical outcomes based on breast specimen size, classified as small (≤300 g), medium (>300-450 g), large (>450-600 g), and very large (>600 g). RESULTS A total of 728 patients was enrolled. C-NSM was performed in 51% (371/728) of cases, while MA-NSM was done in 49% (357/728). The overall complication rate of MA-NSM was comparable to C-NSM (p = 0.573), but severe complications (Clavien-Dindo, CD III) was significantly reported more following C-NSM, regardless of breast size. During a median follow-up of 52 months, no significant difference in oncological outcomes was observed. Comparing MA-NSM and C-NSM outcomes in large-very large breasts (>450 g), MA-NSM demonstrated significantly less blood loss (p = 0.036) and lower incidence of severe complications (CD ≥ III) compared to C-NSM (p = 0.002). CONCLUSION MA-NSM is feasible for large breasts and offers benefits by reducing blood loss and decreasing the incidence of severe complications (CD ≥ III) in this patient group.

Abstract
OBJECTIVE To compare the clinical and patient-reported outcomes of minimal access and conventional nipple-sparing mastectomy (C-NSM). The secondary outcomes investigated included medical costs and oncological safety. BACKGROUND Minimal-access NSM has been increasingly applied in the treatment of patients with breast cancer. However, prospective multicenter trials comparing robotic-assisted NSM (R-NSM) versus C-NSM or endoscopic-assisted NSM (E-NSM) are lacking. METHODS A prospectively designed 3-arm multicenter, nonrandomized trial (NCT04037852) was conducted from October 1, 2019 to December 31, 2021, to compare R-NSM with C-NSM or E-NSM. RESULTS A total of 73 R-NSM, 74 C-NSM, and 84 E-NSM procedures were enrolled. The median wound length and operation time of C-NSM was (9 cm, 175 minutes), (4 cm, and 195 minutes) in R-NSM, and (4 cm and 222 minutes) in E-NSM. Complications were comparable among the groups. Better wound healing was observed in the minimal-access NSM group. The R-NSM procedure was 4000 and 2600 United States Dollars more expensive than C-NSM and E-NSM, respectively. Wound/scar and postoperative acute pain evaluation favored the use of minimal access NSM over C-NSM. Quality of life in terms of chronic breast/chest pain, mobility, and range of motion of the upper extremity showed no significant differences. The preliminary oncologic results showed no differences among the 3 groups. CONCLUSIONS R-NSM or E-NSM is a safe alternative if compared with C-NSM in terms of perioperative morbidities, especially with better wound healing. The advantage of minimal access groups was higher wound-related satisfaction. Higher costs remain one of the major limiting factors in the widespread adoption of R-NSM.

Single-port three-dimensional (3D) endoscopic-assisted breast surgery-preliminary results and patient-reported satisfaction in 145 breast cancer and gynecomastia cases. World J Surg Oncol 2023; 21:335. [PMID: 37880770 PMCID: PMC10601236 DOI: 10.1186/s12957-023-03191-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/13/2023] [Accepted: 09/17/2023] [Indexed: 10/27/2023] Open
Abstract
BACKGROUND Minimal-accessed (robotic and endoscopic) breast cancer surgery is increasingly performed due to better cosmetic results and acceptable oncological outcomes. This study aims to demonstrate the clinical safety and patient-reported cosmetic satisfaction of single-port three-dimensional endoscopic-assisted breast surgery (S-P 3D EABS), which is our new endoscopic surgical innovation, in both malignant and benign breast conditions. METHODS Patients who underwent S-P 3D EABS from 1 August 2018 to 31 July 2022 in a single institution were enrolled. Clinical outcomes of this procedure were retrospectively reviewed, and the patient-reported cosmetic satisfaction was evaluated by a questionnaire and reported herein. RESULTS During the study period, 145 patients underwent 164 procedures of S-P 3D EABS. One hundred fifty (91.5%) procedures were endoscopic-assisted nipple-sparing mastectomy (S-P 3D E-NSM; 117 therapeutic procedures for breast cancer, 13 prophylactic mastectomies, 20 procedures for gynecomastia). Fourteen (8.5%) procedures of endoscopic-assisted breast-conserving surgery (S-P 3D E-BCS) were performed (12 S-P 3D E-BCS, 2 S-P 3D E-BCS with 3D videoscope-assisted partial breast reconstruction, which was 1 case of latissimus dorsi flap and 1 case of omental flap). The mean operative time was 245 ± 110 min in S-P 3D E-NSM and 260 ± 142 min in S-P 3D E-BCS. The mean intraoperative blood loss was 49.7 ± 46.9 ml in S-P 3D E-NSM and 32.8 ± 17.5 ml in S-P 3D E-BCS. Subnipple biopsy showed positive malignancy in 3 (2.6%) S-P 3D E-NSM patients. None of the S-P 3D E-BCS patients found margin involvement; however, 3 (2.6%) reported margin involvement in S-P 3D E-NSM patients. Thirty-two complications were found (24.6%): 7 (5.3%) transient nipple-areolar complex (NAC) ischemia, 7 (5.3%) partial NAC necrosis, 1 (0.7%) total NAC necrosis, and 1 (0.7%) implant loss. During the mean follow-up time of 34 months, there were 2 (1.5%) patients with locoregional recurrence, 9 (6.9%) distant metastasis, and 2 (1.5%) mortality. 78.6% (77/98) of patients answering the cosmetic-evaluated questionnaire reported good and excellent overall satisfaction. CONCLUSIONS S-P 3D EABS is a novel surgical innovation, which is able to perform safely in either malignant or benign breast conditions and offer promising cosmetic results.

Abstract
Purpose The primary objective is to optimize the population eligible for Mammotome Minimally Invasive Surgery (MIS) by refining selection criteria. This involves maximizing procedure benefits, minimizing malignancy risk, and reducing the rate of malignant outcomes. Patients and methods A total of 1158 female patients who came to our hospital from November 2016 to August 2021 for the Mammotome MIS were analyzed retrospectively. Following χ2 tests to screen for risk variables, binary logistic regression analysis was used to determine the independent predictors of malignant lesions. In addition, the correlation between age and lesion diameter was investigated for BI-RADS ultrasound (US) category 4a lesions in order to better understand the relationship between these variables. Results The malignancy rates of BI-RADS US category 3, category 4a and category 4b patients who underwent the Mammotome MIS were 0.6% (9/1562), 6.4% (37/578) and 8.3% (2/24) respectively. Malignant lesions were more common in patients over the age of 40, have visible blood supply, and BI-RADS category 4 of mammography. In BI-RADS US category 4a lesions, the diameter of malignant tumor was highly correlated with age, and this correlation was strengthened in patients over the age of 40 and with BI-RADS category 4 of mammography. Conclusion The results of this study demonstrate that the clinical data and imaging results, particularly age, blood supply, and mammography classification, offer valuable insights to optimize patients' surgical options and decrease the incidence of malignant outcomes.

Abstract
Importance Minimal access breast surgery (MABS) has been used in breast cancer management. However, long-term prognostic data associated with MABS vs conventional breast surgery (CBS) are lacking. Objective To investigate long-term therapeutic outcomes associated with MABS vs CBS for breast cancer management. Design, Setting, and Participants In this single-center retrospective cohort study, 9184 individuals were assessed for inclusion. After exclusions, 2412 adult female individuals were included who were diagnosed with stage 0 to III breast cancer, underwent unilateral breast surgery between January 2004 and December 2017, and had no distant metastasis or history of severe underlying disease. Propensity score matching was performed to minimize selection bias. Data were analyzed from January 1, 2004, to December 31, 2019. Exposures MABS or CBS. Main Outcomes and Measures Data on demographic and tumor characteristics and long-term outcomes were collected and analyzed. Results This study included 2412 patients (100% female; median [IQR] age, 44 [40-49] years). Of these, 603 patients underwent MABS (endoscopic, endoscopy-assisted, or robot-assisted procedures in 289, 302, and 12 patients, respectively) and 1809 patients underwent CBS. The median follow-up time was 84 months (93 in the MABS group and 80 months in the CBS group). Intergroup differences were not significant for the following parameters: 10-year local recurrence-free survival (93.3% vs 96.3%; hazard ratio [HR], 1.39; 95% CI, 0.86-2.27; P = .18), regional recurrence-free survival (95.5% vs 96.7%; HR, 1.38; 95% CI, 0.81-2.36; P = .23), and distant metastasis-free survival (81.0% vs 82.0%; HR, 0.95; 95% CI, 0.74-1.23; P = .72). The 5-, 10-, and 15-year disease-free survival rates in the MABS group were 85.9%, 72.6%, and 69.1%, respectively. The corresponding rates in the CBS group were 85.0%, 76.6%, and 70.7%. The intergroup differences were not significant (HR, 1.07; 95% CI, 0.86-1.31; P = .55). The 5-, 10-, and 15-year overall survival rates in the MABS group were 92.0%, 83.7%, and 83.0%, respectively. The corresponding rates in the CBS group were 93.6%, 88.7%, and 81.0%. The intergroup differences were not significant (HR, 1.29; 95% CI, 0.97-1.72; P = .09). Post hoc subgroup analysis showed no significant intergroup differences in disease-free survival. Conclusions and Relevance In this cohort study, long-term outcomes following MABS were not significantly different from those following CBS in patients with early-stage breast cancer. MABS may be a safe and feasible alternative in this patient population.
