RESUMEN
PURPOSE: Breast-conserving surgery is the preferred treatment for breast cancer; however, its associated risk of local recurrence is higher than that of mastectomy. We performed a comparative analysis of four patient-reported outcomes, psychosocial well-being, sexual well-being, breast satisfaction, and physical well-being of the chest, and quality of life after three surgical approaches, breast-conserving therapy (BCT), mastectomy alone, and mastectomy with breast reconstruction, for breast cancer treatment. METHODS: A cross-sectional survey using the BREAST-Q questionnaire and including patients who had undergone breast surgery at least 1 year prior to survey completion was performed. The analysis included 1035 patients (mean age, 55.0 ± 9.1 years) who underwent breast reconstruction, 116 patients (mean age, 63.6 ± 12.2 years) who underwent mastectomy, and 64 patients (mean age, 60.8 ± 12.2 years) who underwent BCT. RESULTS: Patients who underwent reconstruction had significantly higher psychosocial well-being scores (62.8 ± 18.4) than those who underwent BCT (57.0 ± 23.6) and mastectomy (50.8 ± 16.8) (p < 0.01). However, significant differences in self-acceptance scores among all patients were not observed. Regarding sexual well-being and breast satisfaction, patients who underwent mastectomy had significantly lower scores (29.9 ± 18.7 and 41.8 ± 17.7, respectively) than those who underwent BCT (45.8 ± 26.6 and 58.3 ± 17.5, respectively) and reconstruction (46.4 ± 20.3 and 58.8 ± 15.4, respectively) (p < 0.01). Physical well-being of the chest scores were not significantly different among all patients (p = 0.14). Symptoms after mastectomy included chest muscle pain and arm movement impairment. Breast pain was a notable symptom after BCT. CONCLUSION: The study findings provide valuable insights regarding patient-reported outcomes, highlight the potential benefits of breast reconstruction, and emphasize the importance of patients' preferences.
RESUMEN
The forkhead box O (FOXO) family has been extensively investigated in aging and metabolism, but its role in tissue-repair processes remains largely unknown. Herein, we clarify the molecular aspect of the FOXO family in skin wound healing. We demonstrated that Foxo1 and Foxo3a were both up-regulated during murine skin wound healing. Partial knockout of Foxo1 in Foxo1(+/-) mice throughout the body led to accelerated skin wound healing with enhanced keratinocyte migration, reduced granulation tissue formation, and decreased collagen density, accompanied by an attenuated inflammatory response, but we observed no wound phenotype in Foxo3a(-/-) mice. Fibroblast growth factor 2, adiponectin, and notch1 genes were significantly increased at wound sites in Foxo1(+/-) mice, along with markedly altered extracellular signal-regulated kinase 1/2 and AKT phosphorylation. Similarly, transient knockdown of Foxo1 at the wound site by local delivery of antisense oligodeoxynucleotides enhanced skin wound healing. The link between FOXO1 and scarring extends to patients, in particular keloid scars, where we see FOXO1 expression markedly increased in fibroblasts and inflammatory cells within the otherwise normal dermis. This occurs in the immediate vicinity of the keloid by comparison to the center of the mature keloid, indicating that FOXO1 is associated with the overgrowth of this fibrotic response into adjacent normal skin. Overall, our data indicate that molecular targeting of FOXO1 may improve the quality of healing and reduce pathological scarring.

Silicone breast implants are popularly used for breast reconstruction. As more patients receive long-term silicone breast implants, the number of replacement operations will also increase, and some patients prefer to change from silicone breast implantation to tertiary autologous reconstruction. We evaluated the safety of tertiary reconstruction and assessed patient views regarding the two reconstruction methods. We retrospectively analyzed patient backgrounds, surgical characteristics, and silicone breast implantation retention periods until tertiary reconstruction. We designed an original questionnaire to assess patient opinion regarding silicone breast implantation and tertiary reconstruction. Twenty-three patients (24 breasts) with decisive factors of patient-initiated elective surgery (n = 16), contralateral breast cancer occurrence (n = 5), or late-onset infection (n = 2) underwent tertiary reconstruction. The median time from silicone breast implantation to tertiary reconstruction was significantly shorter in patients with metachronous cancer (47 months) than that in those undergoing elective surgery (92 months). Complications included partial flap loss (n = 1), seroma (n = 6), hematoma (n = 5), and infection (n = 1). Total necrosis did not occur. Twenty-one patients responded to the questionnaire. The satisfaction score was significantly higher for abdominal flaps than for silicone breast implants. When presented with the option to select the initial reconstruction method again, 13 of 21 respondents chose silicone breast implantation. Tertiary reconstruction is beneficial because it reduces clinical symptoms and cosmetic complaints and is recommended as a bilateral reconstruction method, especially for patients with metachronous breast cancer. However, silicone breast implants, which are minimally invasive and associated with shorter hospital stays, were simultaneously found to be sufficiently attractive to patients.

BACKGROUND: While breast reconstruction often improves the quality of life of patients with locally advanced breast cancer, there is still no consensus on its safety. This retrospective report aimed to verify the safety of immediate breast reconstruction for locally advanced breast cancer. METHODS: We retrospectively analyzed 500 breast cancer surgeries performed between January 2005 and December 2019 at our hospital, including 120 immediate breast reconstructions. The following five items were analyzed: the patients' choice of reconstruction method, rate of chemotherapy and radiotherapy, surgical margin positivity rate, complications associated with surgery, overall survival rate, and breast cancer-free survival rate. RESULTS: Sixty-three of the 120 patients underwent autologous breast reconstruction. Of those who underwent reconstruction surgery, 95.8% received chemotherapy and 78.3% underwent post-mastectomy radiation therapy. Reconstruction failed in 8 cases with tissue expander and in 1 case with free TRAM flap. Breast reconstruction surgery was not a factor in delaying adjuvant therapy, but complications requiring intervention tended to increase the duration of adjuvant therapy. There was no statistically significant difference in the rate of surgical margin positivity, overall survival rate, or breast cancer-free survival rate. CONCLUSIONS: Although complications associated with reconstructive surgery occurred, appropriate intervention prevented delays in breast cancer treatment, and the complications did not negatively affect the overall or breast cancer-free survival rates. Our study found no evidence to avoid primary breast reconstruction in patients with locally advanced breast cancer.

Capsular contracture is a common complication among breast implant reconstruction patients. The aim of this study was to assess the duration of and risk factors associated with capsular contracture by comparing 2 reconstruction methods. METHODS: The medical charts of patients who received a reconstructed breast implant and underwent a capsule revision surgery were retrospectively reviewed. We examined patients' background, skin expansion duration, time taken until capsule revision surgery, tissue expander/implant size, and postoperative complications. RESULTS: Of the total 74 breasts [42 immediate reconstruction (Immediate) and 32 delayed reconstruction (Delayed) breasts], the age at the revision surgery was significantly older in the Delayed (59 years) than in the Immediate category (50 years; P = 0.002). The time taken until the capsule revision surgery was significantly shorter for the Immediate (63.5 months) than for the Delayed (121 months; P < 0.0001). The postoperative complication rate after expander insertion was significantly higher in the Immediate (62.5%) than in the Delayed (21.1%; P < 0.0001). The size of the expander and implant was significantly smaller in the Immediate (expander, 300 mL; implant, 240 mL) than in the Delayed (expander, 400 mL; implant, 300 mL) (expander, P = 0.008; implant, P = 0.004). CONCLUSIONS: The immediate reconstruction breasts had a shorter time to capsule revision surgery than the delayed reconstruction breasts. Our study suggested that the shorter time in immediate reconstruction was affected by postoperative complications after mastectomy with expander insertion and by selection of a smaller sized expander and implant.
RESUMEN
Argonaute 2 bound mature microRNA (Ago2-miRNA) complexes are key regulators of the wound inflammatory response and function in the translational processing of target mRNAs. In this study, we identified four wound inflammation-related Ago2-miRNAs (miR-139-5p, miR-142-3p, miR-142-5p, and miR-223) and show that miR-223 is critical for infection control. miR-223Y/- mice exhibited delayed sterile healing with prolonged neutrophil activation and interleukin-6 expression, and markedly improved repair of Staphylococcus aureus-infected wounds. We also showed that the expression of miR-223 was regulated by CCAAT/enhancer binding protein alpha in human neutrophils after exposure to S. aureus peptides. Treatment with miR-223Y/--derived neutrophils, or miR-223 antisense oligodeoxynucleotides in S. aureus-infected wild-type wounds markedly improved the healing of these otherwise chronic, slow healing wounds. This study reveals how miR-223 regulates the bactericidal capacity of neutrophils at wound sites and indicates that targeting miR-223 might be of therapeutic benefit for infected wounds in the clinic.

Nanoparticle albumin-bound paclitaxel (nab-PTX) is a key drug used in breast cancer treatment which often causes chemotherapy-induced peripheral neuropathy (CIPN). No effective approach for CIPN control has been established to date. This study assessed a new approach to CIPN integrating two concepts: compression therapy using stockings and sleeves, and medication therapy using selected prophylactic drugs, including goshajinkigan, which we named the "3S" approach. Fourteen breast cancer patients were divided into a 3S group (n=7) and a control group (n=7), and were treated with 260 mg/m(2) of nab-PTX once every three weeks. CIPN initially developed in five control-group patients and one 3S-group patient (p=0.03). Across all cycles, the CIPN grades, as determined by the Common Terminology Criteria for Adverse Events (CTCAE), were significantly lower in the 3S group than in the control group (p<0.001). The mean nab-PTX dose in the 3S group was 77.1 mg/m(2)/week versus 64.7 mg/m(2)/week in the control group (p<0.01). By controlling the development and severity of CIPN, 3S treatment appears to support the use of the recommended nab-PTX dosing for breast cancer patients.
