Breast Reconstruction in Poland Syndrome Patients with Latissimus Dorsi Myo Flap and Implant: An Efficient Endoscopic Approach Using Single Transverse Axillary Incision.

BACKGROUND: Breast hypoplasia or amastia with pectoralis major muscle defect in female Poland syndrome patients always necessitates surgical intervention. This study aims to introduce an efficient endoscopic technique to perform breast reconstruction in Poland syndrome patients with a latissimus dorsi myo flap and an implant using a single transverse axillary incision (ELDM + IMPLANT) and to evaluate its safety and effectiveness. METHODS: A prospective study was designed to recruit Poland syndrome candidates for ELDM + IMPLANT breast reconstruction. Only one transaxillary incision was made to harvest the LDM flap and create the anterior chest wall pocket. The LDM flap was transposed to the front to reconstruct the breast with a silicone implant. Patient demographics, LDM area, implant size, contralateral symmetry surgery, operative time and post-operative complications were collected. The BREAST-Q reconstruction module was used to evaluate patient quality of life. The disabilities of the arm, shoulder and hand (DASH) outcome questionnaire was used to evaluate patient upper extremity disabilities. RESULTS: Sixteen eligible patients were recruited and received ELDM + IMPLANT-BR. Mean endoscopic time for LDM flap harvesting was 61.6 min. All of the 16 patients recovered uneventfully without any significant complications. The post-operative scores of satisfaction with breast and psychosocial well-being were significantly higher than the pre-operative ones. The score of DASH was 7.1 pre-operatively and 8.3 post-operatively with no significant difference either. The score of satisfaction with outcome was 80.0. CONCLUSIONS: Our proposed ELDM + IMPLANT technique provides a safe and efficient way to reconstruct breasts in Poland syndrome patients with a high satisfaction rate, optimized aesthetic outcome and minimized donor site morbidity.

Different dosage forms of GnRHa with endocrine therapy in premenopausal hormone Receptor-Positive breast cancer.

BACKGROUND: Despite the wide use of a three-month gonadotropin-releasing hormone agonist (3M GnRHa) for ovarian function suppression (OFS) in premenopausal breast cancer patients, it remains unclear whether it is as effective and safe as a one-month GnRHa regimen (1M GnRHa) when combined with selective estrogen receptor modulators (SERMs) or aromatase inhibitors (AIs), especially in younger patients. METHODS: This retrospective cohort study included 1109 premenopausal hormone receptor-positive (HR+) breast cancer patients treated with GnRHa plus SERM or AI. The estradiol (E2) inhibition rate within 1-24 months after treatment with 1M or 3M GnRHa in cohorts and different subgroups was analyzed. RESULTS: Following 1:1 propensity score matching, 950 patients with a mean age of 39 years and a median follow-up of 46 months were included. Both the 1M and 3M groups achieved >90% E2 inhibition within 24 months (94.53% vs 92.84%, 95% CI (-4.78%, 1.41%)), confirming the non-inferiority of 3M GnRHa. Both 1M and 3M GnRHa rapidly and consistently reduced E2 levels. 60 (6.3%) patients experienced incomplete ovarian function suppression (iOFS), with similar rates in the 1M and 3M groups (5.5% vs 7.2%). iOFS mainly occurred within the first 12 months, with age <40 years and no prior chemotherapy being the risk factors. Similar disease-free survival (DFS) and overall survival (OS) were found in the 1M and 3M groups, and in patients with complete and incomplete OFS (p > .05). CONCLUSIONS: The OFS with 3M GnRHa was not inferior to that with 1M GnRHa, regardless of age or combination with a SERM or an AI.

Preoperative Three-Dimensional Measurement-Based Periareolar Augmentation Mastopexy: Indication and Breast Crown Approach.

SUMMARY: At present, there is no uniform and quantitative indication standard for periareolar augmentation mastopexy. The authors proposed an indication algorithm and a matched approach to delineate the outer circle, to optimize the result of this operation. Five parameters, including both implant and breast characteristics, were incorporated to form an indication algorithm based on three-dimensional measurement. The indication follows the principle that the circumference of the outer circle should be no more than two times the inner circle. To delineate the outer circle, a "crown" was made on the breast. The above approaches were used on patients who came for periareolar augmentation mastopexy from October of 2015 to January of 2019. Data analyzed included BREAST-Q score, areola diameter, the distance of the sternal notch to the nipple preoperatively and 1 year postoperatively, the distance of nipple elevation 1 year postoperatively, and complication and revision rates. A total of 28 breasts (14 patients) were included in this study. BREAST-Q scores 1-year postoperatively showed significant increases in Satisfaction with Breasts, Psychosocial Well-Being, and Sexual Well-Being ( p = 0.000). The mean areolar diameter preoperatively and postoperatively was 6.7 ± 1.2 cm and 4.6 ± 0.4 cm, respectively ( p = 0.000), and the mean sternal notch-to-nipple distance preoperatively and postoperatively was 22.2 ± 1.9 cm and 18.6 ± 1.0 cm, respectively ( p = 0.000), with an average nipple elevation of 3.2 ± 1.1 cm. The overall complication rate was 7.1 percent ( n = 2); both cases were areolar spreading. The overall revision rate was 0 percent. This preliminary study demonstrated the safety and efficacy of the indication and breast crown approach in reducing complication and revision rates. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

Chest Wall Reconstruction in Male Poland Syndrome Patients with Endoscopic-Assisted Latissimus Dorsi Muscle Flap Transfer.

BACKGROUND: Pectoralis major absence generates chest wall deformity and always requires surgical intervention. This study aimed to introduce a technique to reconstruct the chest wall for male Poland Syndrome patients with endoscopic latissimus dorsi muscle (ELDM) flap via a single transverse axillary incision and evaluate its safety and effectiveness. METHODS: A prospective study was designed to recruit male Poland Syndrome candidates for ELDM chest reconstruction. By performing a short and hidden transaxillary incision, we created anterior chest wall pocket and transferred the latissimus dorsi muscle (LDM) flap to recontour the chest wall. Data for patient demographics, LDM flap dimension, operative time, and complications were collected. Upper extremity functional disabilities were evaluated by the disabilities of the arm, shoulder and hand (DASH) outcome questionnaire. Satisfaction with the outcome was measured by satisfaction with outcome subscale of the BREAST-Q questionnaire. RESULTS: This study recruited 11 eligible patients to receive ELDM chest wall reconstruction. ELDM flap harvesting averagely consumed 79.9 minutes. Without significant complications, all patients recovered uneventfully. Chest wall anomalies of different severity were corrected safely and effectively. The score of DASH was 3.7±3.3 preoperatively and 4.0±3.7 postoperatively with no statistically significant difference. The score of satisfaction with the outcome was 84.8±14.3. CONCLUSIONS: For chest wall anomalies of different severity in male Poland Syndrome patients, the ELDM technique provides a safe and efficient way to reconstruct the chest wall with a better aesthetic outcome, high satisfaction rate, and satisfactory upper limb function.
