Background: Breast reconstruction post-mastectomy has increasingly emphasized the importance of sensory restoration. This study aimed to evaluate the comparative efficacy of anterior versus lateral cutaneous intercostal nerve branches in neurotization during abdominal-based autologous breast reconstruction. Methods: Through a systematic literature search and meta-analysis, we reviewed studies published between January 2003 and August 2023. Our methods involved categorizing studies based on the nerve branch used, extracting relevant data, and conducting a quality assessment. To determine the difference in the magnitude of sensory recovery, a meta-analysis was conducted to pool the effect sizes (mean differences) from individual studies. Given the potential for heterogeneity across studies, a random-effects model was employed using the DerSimonian and Laird method. Subgroup analysis was then performed to separately evaluate the effect sizes for the anterior and lateral groups. Results: We identified five studies for the anterior group and five studies for the lateral group. The anterior group included a total of 225 non-neurotized and 240 neurotized breasts, while the lateral group consisted of 62 non-neurotized and 51 neurotized breasts. The anterior group exhibited superior sensory recovery compared to the lateral group (p = 0.08 for the common effect model). The result was borderline significant, suggesting a trend towards a difference between the two groups. In terms of patient-reported outcomes, the anterior group provided data, while the lateral group lacked such data, underscoring a potential research gap. Conclusions: Results indicated a trend favoring the anterior cutaneous branch, with studies showing improved sensory outcomes and patient satisfaction. However, the choice between the two should be individualized, considering the patient’s unique needs and the surgeon’s expertise. Full article

Background: Immediate direct-to-implant (DTI) breast reconstruction is associated with high patient satisfaction and faster recovery. However, concerns remain for patients requiring post-mastectomy radiation therapy (PMRT). While PMRT improves overall survival for breast cancer patients, it has been associated with increased implant-specific complications such as capsular contracture, infection, and implant loss. As the impact of PMRT on pre-pectoral DTI specifically is not well understood, the goal of this systematic review was to evaluate the impact of PMRT on outcomes in this growing patient population. Methods: PubMed, EMBASE, and Web of Science were systematically reviewed for articles published from 1 January 2000 to 23 December 2024 investigating outcomes after prepectoral DTI reconstruction with exposure to PMRT. Demographic, clinical, and post-operative variables were recorded for PMRT and non-PMRT cohorts, and primary outcomes included infection, capsular contracture, implant loss, and wound healing complications. Meta-analysis was performed for key outcomes using the Mantel-Haenszel method. Results: Of 472 initially identified records, seven studies met inclusion criteria with a combined total of 343 prepectoral DTI reconstructions exposed to PMRT and 1385 reconstructions not exposed to PMRT. PMRT significantly increased the odds of any complication (OR 2.11, p = 0.01), implant loss (OR 1.88, p = 0.02), infection (OR 2.76, p = 0.004), and capsular contracture (OR 8.88, p < 0.001). However, PMRT was not associated with significantly increased odds of wound healing complications (OR 1.5, p = 0.36). Conclusions: PMRT after pre-pectoral DTI reconstruction significantly increases odds of complications, including infection, capsular contracture, and reconstructive failure. Plastic surgeons should be mindful of the sequelae of PMRT with prepectoral DTI reconstruction to improve pre-operative counseling and shared decision-making. Full article

Thanatosomes (hyaline globules or death bodies) are histologically observed in various non-neoplastic and neoplastic conditions. Some of these globules are associated with apoptotic cell death. Only six documented cases of thanatosomes have been reported in breast tumors. In this rare case involving a 64-year-old Japanese woman diagnosed as having rectal cancer, preoperative computed tomography scanning revealed breast cancer in her right breast. Following a right total mastectomy, a tumor characterized as apocrine carcinoma (carcinoma with apocrine differentiation) containing thanatosomes was discovered. These globules are PAS positive and diastase resistant, exhibit deep fuchsinophilic staining with Masson’s trichrome, stain dark blue with PTAH, and are negative for mucin by Alcian blue. The tumor cells tested positive for the androgen receptor, FOXA1, and GCDFP15. Human epidermal growth factor type 2 (HER2)/neu score was 3+/positive, and the Ki-67 labeling index was 60%. Thus, the tumor represented high-grade, HER2-enriched apocrine carcinoma. Thanatosomes are immunoreactive to cleaved caspase-3 and are histological markers of high cell turnover and apoptotic cell death. Therefore, in this nonspecific microscopic neoplastic condition, they are typically linked to high-grade tumors, as this case showed. This report presents a rare case of apocrine breast cancer featuring a limited number of thanatosomes. Full article

Background/Objectives: The aim of this case series is to evaluate the outcomes and safety of video-assisted mastectomy, illustrating the harmonious collaboration of oncologic and plastic surgery. This novel minimally invasive technique allows immediate prosthetic reconstruction and represents a cost-effective alternative to robotic breast surgery. Methods: Video-assisted, single-port nipple-sparing mastectomies were performed in patients with small to medium-sized breasts, followed by immediate direct-to-implant reconstruction with either prepectoral or dual plane implant placement. The patients’ electronic medical records were analyzed, including demographic characteristics, operative times and histopathology reports. Results: A total of 18 patients underwent successful video-assisted mastectomy, without conversion to traditional open procedure. Fifteen of the operations were risk-reducing mastectomies. Twelve patients had complementary procedures performed concurrently on the previously operated contralateral breast (delayed reconstruction/expander-to-implant exchange). Moreover, three patients benefited from additional minimally invasive techniques during the same surgery (prophylactic laparoscopic hysterectomy). Immediate breast reconstruction with polyurethane or microtextured breast implants up to 450 cc was performed, with satisfactory aesthetic outcomes and no cancer recurrences at 6 to 12 months postoperative follow-up. Early complications included transient hypercapnia, areolar congestion and cellulitis. No skin necrosis or implant-related complications were reported. The most frequently encountered late issues were contour irregularities. Conclusions: Video-assisted mastectomy facilitates the safe removal of proven pathologic or healthy breast tissue with minimal damage to the breast’s skin envelope, facilitating single-stage breast reconstruction.

Background and Objectives: Lymphedema is one of the most important morbid complications of modified radical mastectomy (MRM) surgery. It can cause limb movement restriction and psychosocial deformities in some patients. This study aimed to determine and compare the physiological and pathological changes that develop in the axillary venous structures in patients who underwent axillary lymph node dissection (ALND) and sentinel lymph node biopsy (SLNB). Materials and Methods: Patients diagnosed with breast cancer who underwent MRM and breast-conserving surgery (BCS) plus SLNB between 2017 and 2022 were retrospectively examined. The patients’ operation side and contralateral axillary vein diameter and the difference between them, axillary vein flow rate and the difference between them, axillary vein wall thickness and the difference between them, severity of lymphedema, extremity joint restriction examination, and the Nottingham Health Profile (NHP) data were recorded. The relationship of these parameters with the lymph node dissection width and radiotherapy was analyzed. Results: Fifty-eight patients in total were included in the study. In the distribution of lymphedema and lymphedema severity according to ALND groups, there is a statistically significant difference (p < 0.001). A statistically significant difference was determined in the distribution of the difference in the axillary vein blood flow rate and axillary vein diameter difference between the two arms according to the lymph node dissection groups. In the distribution of physical therapy and rehabilitation scales according to the lymph node dissection groups, a significant difference was found in the disabilities of the arm, shoulder, and hand (DASH), shoulder flexion restriction variables, and NHP sleep variables (all p < 0.001). Conclusions: This study demonstrated that ALND leads to more pronounced physiological and pathological changes in axillary venous structures—including increased vein wall thickness, altered flow rates, and diameter differences—compared to SLNB combined with breast-conserving surgery. These changes may be attributed to lymphovenous disruption and postoperative edema. Furthermore, radiotherapy appears to contribute to these changes, though to a lesser extent than ALND. Therefore, SLNB followed by radiotherapy may be preferable in eligible patients to reduce postoperative complications such as lymphedema, joint restriction, and sleep disturbances. Full article

Mammary tumors are the most common neoplasms in female dogs, with mastectomy being the primary treatment. The impact of mastectomy type on survival remains unclear. This study evaluated the effect of different surgical techniques on the survival of female dogs with mammary carcinomas. A total of 307 dogs with 734 mammary tumors were analyzed. Ages ranged from 1 to 17 years, with mixed breeds comprising 48.9%. Most tumors (92.9%) were malignant, predominantly carcinoma in a mixed tumor (30.2%). Unilateral mastectomy was the most common technique (65.8%). Lumpectomy showed the shortest mean survival (179 days) and was associated with a 4.9-fold increased risk of death (p = 0.009). There was no significant association between surgical technique and overall survival or recurrence of mammary carcinoma (p = 0.2). This study relied on owner-reported data for survival and tumor recurrence. Lumpectomy appears to be associated with shorter survival times in female dogs with mammary carcinoma. Therefore, it may be advisable to reconsider this technique as a primary treatment option. Full article

Background: A surgical therapy for breast cancer, robot-assisted nipple-sparing mastectomy (RANSM) has gained popularity because it may offer better cosmetic results than traditional nipple-sparing mastectomy (CNSM). Data regarding RANSM’s viability and security are still scarce, nevertheless. Comparing the surgical results of RANSM and CNSM in a single-center experience was the goal of this study. Methods: 57 patients who had nipple-sparing mastectomy procedures performed at our facility between January and December 2021 were included in this retrospective research. Of them, 49 patients had CNSM, and 8 patients had RANSM. Analysis was performed on pain scores, length of hospital stay, postoperative complications, patient demographics, and operating time. Results: The mean total operative time was longer for RANSM group was 148 min compared to 117 min for the CNSM group; however, this difference was not statistically significant (p = 0.083). The mean duration of hospital stay was shorter for the RANSM group than for the CNSM group (10.75 days vs. 2.92 days, respectively; p = 0.302). Both groups had similar pain scores on postoperative day 3 (RANSM: 3.50, CNSM: 3.54, p = 0.926). No patient in the RANSM group received adjuvant chemotherapy or radiotherapy, whereas 32.6% of patients in the CNSM group received chemotherapy. The RANSM and CNSM groups experienced complications at rates of 12.5% and 18.4%, respectively (p = 0.571). In contrast to 14.3% in the CNSM group, there were no documented incidences of skin necrosis in the RANSM group. Conclusions: RANSM demonstrated comparable safety to CNSM with potential benefits, including a shorter hospital stay and lower complication rates. These findings support the feasibility of RANSM, particularly in patients prioritizing cosmetic outcomes. To validate these initial findings, more research with larger cohorts and longer follow-up times is necessary. Full article

Pre-metastatic niche (PMN) formation is a critical step in metastatic progression. However, the biological effects of subtherapeutic doses of ionizing radiation (SDIRs) following radiotherapy on this process remain unclear. Using a 4T1 breast cancer mouse model, we investigated the effects of SDIRs (3 × 0.3 Gy) on lung PMN development and metastasis upon SDIR exposure on days 8–10 post-tumor injection, followed by mastectomy and analyzed on day 24. SDIRs significantly increased the total metastatic volume (TMV) in lungs, suggesting an accelerated PMN formation. Mechanistically, the SDIR acted as an early catalyst for niche priming, upregulating Bv8 expression, enhancing neutrophil recruitment, and increasing MMP9, S100A8, and Il6 production in the PMN by day 11. Moreover, SDIR drives metastasis through distinct mechanisms. Proteomic analysis revealed SDIR-driven metabolic reprogramming, with a shift away from fatty acid metabolism toward glycolysis and lipid accumulation within the PMN. This shift contributes to extracellular matrix (ECM) remodeling, immune modulation, and the upregulation of adhesion-related pathways, shaping a microenvironment that accelerates metastatic outgrowth. By reprogramming the pre-metastatic lung, the SDIR highlights the need to integrate organ-specific radiation exposure into metastasis models. Metabolic and immune-stromal pathways emerge as potential therapeutic targets, underscoring the importance of refining radiotherapy strategies to mitigate unintended pro-metastatic effects.

Background: Implant-based breast reconstruction (IBBR) is a widely adopted technique following mastectomy in breast cancer patients. However, the impact of chemotherapy type and duration on the development of capsular contracture remains unclear. Methods: This nationwide, retrospective, cohort study used Health Insurance Review and Assessment Service data to identify breast cancer patients who received chemotherapy and underwent immediate IBBR between January 2015 and December 2018. Follow-up continued until January 2024, with a median follow-up of 5.2 years. A total of 4303 patients (direct-to-implant [DTI], n = 2083; tissue expander insertion [TEI], n = 2220) were included. Results: Chemotherapy type and duration were not significantly associated with capsular contracture risk in either the DTI or TEI groups. In the DTI cohort, no significant difference in contracture incidence was found between neoadjuvant and adjuvant chemotherapy before or after matching (p = 0.056 and p = 0.121, respectively). In the TEI cohort, an initially significant difference (p = 0.019) was no longer observed after matching (p = 0.213). Similarly, chemotherapy duration (≤12 weeks vs. >12 weeks) did not impact contracture risk in either cohort. Multivariate analysis identified age, radiotherapy, lymphedema, and axillary lymph node dissection (ALND) as independent risk factors for contracture (p < 0.005). Comorbidities, such as diabetes and autoimmune diseases, also showed no significant association with contracture risk. Conclusions: These findings suggest that chemotherapy decisions should not be guided by contracture concerns. Instead, optimizing reconstruction outcomes should focus on modifiable factors, such as radiotherapy, lymphedema, and ALND. Full article

Background: Robotic surgical systems offer enhanced precision, motion scaling, tremor filtration, and visualization, making them highly suitable for the complex anatomical demands of plastic and reconstructive surgery. While widely implemented in other specialties, their integration in plastic surgery remains limited. This systematic review evaluates the clinical applications, outcomes, and limitations of robotic-assisted techniques in plastic and reconstructive procedures. Methods: Following PRISMA guidelines, a systematic search was conducted across PubMed, Embase, Scopus, and Web of Science for studies published between January 1980 and March 2025. Clinical studies reporting robotic applications in plastic surgery were included, while cadaveric, animal, and non-English studies were excluded. Data extraction and quality assessment were performed using Covidence and validated tools including the CARE checklist, NOS, GRADE, and SYRCLE. A total of 1428 studies were screened, and 31 met the inclusion criteria. Results: Robotic systems were primarily applied in microsurgery (n = 16), breast reconstruction (n = 8), and craniofacial/aesthetic surgery (n = 7). Common platforms included the Symani Surgical System, Da Vinci systems, and ARTAS. Robotic-assisted approaches improved precision, aesthetic outcomes, flap survival, and patient satisfaction, particularly in procedures involving lymphaticovenous anastomosis and nipple-sparing mastectomy. However, challenges included steep learning curves, longer operative times, high equipment costs, and the lack of haptic feedback. Quality assessment rated all studies as moderate. Conclusions: Robotic-assisted surgery demonstrates considerable potential in enhancing plastic and reconstructive outcomes. As systems become more compact, cost-effective, and integrated with AI and biomimetic technologies, their broader adoption is anticipated. Further high-quality studies are needed to optimize these systems and support widespread clinical implementation. Full article

(1) Background: The management of ipsilateral breast cancer recurrence depends on the extent of the tumor, and staging results, and mastectomy is currently the standard of care for previously irradiated patients. Studies are increasingly investigating suitable candidates for the repeated use of breast-conserving approaches as an alternative to mastectomy. But this includes the crucial necessity for curative reirradiation (Re-RT). The therapeutic challenge in reirradiation involves finding a balance between tumor control and the risk of severe toxicity from cumulative radiation doses in previously irradiated organs. Re-RT options include the use of brachytherapy, intraoperative radiotherapy, or external beam RT with photons or electrons. The application of particle therapy using proton beam therapy represents an innovative radiotherapeutic technique for breast cancer patients that might offer advantageous physical properties, a superior dose reduction to adjacent organs-at-risk, and effective target volume coverage with lower integral doses to the patient’s whole body. In addition, this technique could potentially offer higher radiobiological effects and tumor responses. (2) Methods: The BREAST trial (NCT06954623) will be conducted as a prospective, single-arm, phase II study in 20 patients with histologically proven invasive breast cancer recurrences after repeat breast-conserving surgery and with an indication for local reirradiation. The patients will receive partial-breast re-RT with proton beam therapy in 15 once-daily fractions up to a total dose of 40.05 Gy(RBE), delivered with active raster scanning. The required time interval will be 1 year after previous RT to the ipsilateral breast. (3) Results: The following results will be reported: The primary endpoint is defined as the cumulative overall occurrence of (sub)acute skin toxicity of grade ≥ 3 within 6 months after the start of re-RT. Secondary outcome includes an analysis of the local, regional, and distant control, progression-free and overall survival, quality of life, and cosmesis. The explorative and translational objectives of this study include planning comparisons to other RT techniques and irradiation types, dosimetric evaluations, analyses of radiological imaging features, and translational assessments of cardiac toxicity biomarkers and tumor markers. (4) Conclusions: Overall, the aim of this study is to evaluate the potential of proton beam therapy for partial breast reirradiation and to establish the underlying data for a randomized trial.

Cancerization of lobules (COL) is defined as the involvement of lobular acini by ductal carcinoma in situ (DCIS). Whether it represents a morphological variation in DCIS or a secondary extension of DCIS into lobules is debatable. The relation between COL and the probability of invasion is conflicting among different studies. We assessed if COL is a predictor of adverse pathological outcomes in mastectomy specimens. We reviewed the clinicopathological data of patients who underwent partial or total mastectomy for DCIS during a 3-year period (January 2015 until December 2017). Pathological parameters and follow-up data were collected. Whole-tissue hematoxylin and eosin (H&E) slides were reviewed and re-evaluated for COL. Cases with COL were stained immunohistochemically for E-cadherin and p120 to confirm the ductal phenotype of the neoplasms. In total, 171 mastectomies were identified including 65 specimens with pure DCIS and 106 specimens with DCIS with invasive carcinoma. COL was identified in 73 specimens. COL was significantly associated with adverse pathological outcomes including higher DCIS nuclear grade (p-value = 0.006), central (expansive “comedo”) necrosis (p-value = 0.008), presence of DCIS within or less than 2 mm from the surgical resection margin(s) (p-value = 0.004), higher percentage of blocks/slides with DCIS (p-value < 0.001), and extensive intraductal component (EIC) (applicable in cases with invasion) (p-value < 0.001). Invasion was seen in approximately two-thirds of the cases regardless of the presence of COL, with no statistical significance. Ninety-eight patients achieved 60 months of follow-up, of which only one patient developed local DCIS recurrence and had COL and EIC. Four other patients developed metastatic disease related to the invasive component. While other studies have previously hypothesized that COL may be associated with a worse pathological outcome at mastectomy, our results show that it may indeed be a measure of a higher disease burden representing EIC; however, it is not associated with an increased risk of detecting invasive carcinoma.

Background: This study compared the change in pre- and postoperative health-related quality of life (HRQoL) among breast cancer patients undergoing breast-conserving surgery (BCS), total mastectomy no reconstruction (TMNR), and total mastectomy immediate breast reconstruction (MIBR). Patient factors associated with postoperative anxiety and depression were also identified. Methods: This prospective cohort study enrolled breast cancer patients between September 2017 and August 2020. HRQoL changes from preoperative to six months postoperative were compared using patient-reported outcome tools assessing anxiety, depression, pain, perceived health, breast satisfaction, psychosocial, physical, and sexual well-being and analyzed with ANOVA and linear regression. Results: A total of 471 patients completed preoperative and postoperative surveys (BCS: 313, TMNR: 60, MIBR: 98). Postoperative anxiety decreased across all modalities, with MIBR showing the greatest reduction (p = 0.03), though still exhibiting the highest postoperative anxiety (p = 0.05). Depression and perceived health scores showed no significant difference in change across modalities (p = 0.15, p = 0.48). MIBR patients showed the greatest increase in pain (p = 0.05) and the highest postoperative pain scores (p = 0.04). All three modalities showed a clinically significant decline in physical and sexual well-being. TMNR and MIBR had additional reductions in breast satisfaction, with TMNR also showing a decline in psychosocial well-being. Absolute postoperative scores for breast satisfaction, psychosocial, physical, and sexual well-being remained highest in BCS compared to TMNR and MIBR (p < 0.01, for each domain). In multivariable regression analysis, postoperative depression and anxiety scores did not differ between surgical modalities, but younger age was significantly associated with higher postoperative depression, pain and anxiety (p < 0.01), and adjuvant chemotherapy with higher postoperative depression (p < 0.01). Conclusions: BCS may have better overall HRQoL outcomes, specifically in breast satisfaction, psychosocial, physical, and sexual well-being, compared to TMNR and MIBR. Additionally, younger age, rather than surgical modality, was found to be associated with higher postoperative depression, pain, and anxiety scores. Full article

Background: The use of dynamic magnetic resonance imaging (MRI) for the evaluation, detection, and characterization of ductal carcinoma in situ (DCIS) has been increasing; however, its application in this context remains controversial and uncertain. Materials: A retrospective study including women with pure DCIS, confirmed between January 2012 and December 2022 using ultrasound-guided core-needle biopsy (CNB) or stereotaxy-guided vacuum-assisted biopsy (VAB), was conducted. Mammography, ultrasound (US), and MRI of DCIS lesions were evaluated according to histological grade. The size of the DCIS, as assessed by mammography, US, MRI, and final surgical histopathology, was compared using Lin’s concordance correlation and Bland–Altman plots. Results: A total of 144 women (mean age 55.5 ± 10.3 years) with histopathological diagnoses of pure DCIS and no evidence of infiltration in the percutaneous biopsy were included in the study. Microcalcifications were the most prevalent feature observed in mammography (82.63%). Round/punctate morphology was more common in low-grade lesions, while fine pleomorphic morphology was more frequent in medium- and high-grade lesions. Lesions manifesting as microcalcifications only on mammography were significantly associated with intermediate and high-nuclear grade DCIS (p = 0.005). The most common MRI manifestation of DCIS was non-mass enhancement (86.11%). A total of 141 lesions showed enhancement with MRI (sensibility 97.92%). There were no significant differences (p = 0.29) between negative and positive enhancement with MRI and the histological grade of the lesions. There were no significant differences (p = 0.49) between the type of enhancement curve with MRI and the histological grade. Preoperative MRI detected additional malignancies (multifocal, multicentric, or bilateral) in 35 patients (24.31%). Conclusions: DCIS demonstrated enhancement with MRI regardless of histological grade but overestimated the size of the lesions in low-nuclear-grade DCIS. Preoperative MRI identified additional malignancies (multifocal, multicentric, and bilateral lesions) in 24 patients (16.67%), which were confirmed by histopathological examination. These malignancies were either undetected or not visible with mammography and ultrasound. However, MRI also overestimated the size of the DCIS, leading to three unnecessary mastectomies in our study.

Background: Implant-based reconstruction (IBR) is the most common method of breast reconstruction, but complications lead to patient distress and delays in cancer treatment. Management of implant complications is varied with no defined guidelines. The inability to salvage IBR is associated with infection, but the impact of antibiotics remains controversial. We aimed to analyze factors affecting salvage rates of threatened IBR requiring operative intervention. The primary outcomes were the rates of unplanned re-operation for threatened IBR for wound closure, exchange, or explant. We hypothesized antibiotic administration would improve salvage rates. Methods: A retrospective review of patients undergoing mastectomy with IBR from 2012 to 2023 was performed. Threatened IBR was defined as implant exposure, infection, skin necrosis, hematoma, seroma, or wound dehiscence without implant exposure. Management options for patients with implant infection included implant removal and antibiotic treatment, antibiotic treatment alone, implant replacement, washout and implant replacement, or implant removal without a salvage attempt. Results: In total, 6901 patients underwent post-mastectomy IBR, and 184 (2.7%) patients had an unplanned re-operation. A total of 166/184 patients (90.2%) underwent explantation, and 18/184 (9.8%) patients had implant salvage. Between the explant and salvage groups, there were no differences in patient demographics, oncologic treatments, or operative characteristics. The explant group had a higher rate of infection (77.7% vs. 22.2%, p < 0.0001). There was no difference in culture positivity or antibiotic administration history. Conclusions: Implant salvage is feasible but limited by infection. Antibiotic administration does not improve salvage rates. Patient factors, oncologic treatment factors, or operative factors do not impact the ability to salvage. Full article
