Comparing the efficacy of linovera spray plus hydrocortisone cream for breast cancer patients undergoing conformal radiotherapy

BackgroundBreast cancer is one of the most prevalent malignancies globally, with a significant proportion of patients undergoing radiotherapy, a crucial treatment modality that substantially reduces recurrence rates. However, radiotherapy is often complicated by dermatological adverse effects ranging from mild erythema to severe dermal burns. Despite various interventions aimed at mitigating skin toxicities, the efficacy of hyperoxygenated fatty acids (HOFA) in this context remains underexplored. ObjectiveTo evaluate the effectiveness of topical HOFA (Linovera spray) in preventing radiotherapy-induced skin reactions in breast cancer patients undergoing conformal radiotherapy. MethodsThis prospective, randomized, controlled trial enrolled post-partial mastectomy breast cancer patients indicated for conformal radiotherapy targeting lymph node levels and the supraclavicular region, with dosages of 45–50 Gy and a 60 Gy tumor bed boost. Patients with active skin diseases or sensitivity to the study spray were excluded. The intervention group applied hydrocortisone ointment and Linovera spray twice daily to the treatment site, while the control group used only hydrocortisone ointment. Skin reactions were graded using the validated Global Skin Reaction Classification and assessed during radiotherapy weeks 3 and 5. ResultsAll 60 randomized patients (intervention n = 24, control n = 28) developed radiation dermatitis. By week 5, the intervention group showed a statistically significant reduction in dermatitis severity versus controls (p = 0.04). Dermatitis grades also significantly worsened within both groups from week 3–5 (all p < 0.001). ConclusionWhile HOFA-based moisturizers did not statistically impact overall incidence or severity, marginal benefits were observed with prolonged Linovera spray plus hydrocortisone use versus hydrocortisone alone by week 5. Further research is warranted to explore HOFA's potential skin-protective effects.

Orbital metastases from breast cancer: three case reports

Purpose: to describe rare cases of orbital metastases from breast cancer.Material and Methods. Three cases of Luminal A(1) and B(2) breast cancer with orbital metastases were identified and studied during the period from 01.01.2018 to 01.05.2024. Metastasis to the orbit was detected 5, 2 and 1.5 years after radical mastectomy for breast cancer. Patients received chemotherapy and radiation therapy.Results. Cases of orbital metastasis originating from breast cancer were found to have a low frequency, but may be associated with a long period between cancer diagnosis and initiation of treatment. Early detection of breast cancer and its active treatment with chemotherapy and radiation therapy are important factors in preventing orbital metastasis.Conclusion. A routine follow-up surveillance after radical treatment of breast cancer is important because there is an increase risk of developing orbital metastasis. Comprehensive strategies for treating breast cancer metastases can provide long-term disease control.

Impact of breast reconstruction on quality of life in women undergoing mastectomy for breast cancer: a systematic review and meta-analysis using the Breast-Q questionnaire

Introduction: Post-mastectomy breast reconstruction is crucial in breast cancer treatment; however, its impact on women’s quality of life (QOL) remains inadequately understood. The BREAST-Q questionnaire is used for assessing QOL related to breast surgery. Therefore, this study aimed to determine whether there are differences in QOL between women undergoing mastectomy with and without breast reconstruction using the BREAST-Q questionnaire. Methods: We conducted a systematic review and meta-analysis following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 guidelines and registered in PROSPERO. Articles in English, Portuguese, or Spanish were included, and studies on prophylactic mastectomy or breast-conserving surgery, duplicate studies, duplicate data, articles without original data (reviews, editorials, case reports, technical reports) and those without breast reconstruction were excluded. A comprehensive search was conducted across nine scientific databases. The defined search strategy was related to the terms standardized by the MeSH/PubMed controlled vocabularies, including Medical Subject Headings (MeSH), Embase subject headings (Emtree), and their synonyms. Statistical heterogeneity was assessed using the chi-squared and inconsistency tests. Statistical analyses were performed using the R software. A meta-analysis was performed for each BREAST-Q domain when data from multiple studies were available. Results: Of 1266 studies identified, three with 611 participants were included in the meta-analysis. Of these participants, 248 underwent mastectomy without reconstruction and 363 underwent post-mastectomy breast reconstruction. The meta-analysis revealed significantly higher scores in the domains “satisfaction with the breast,” “physical well-being of the chest,” “psychosocial well-being,” and “physical well-being” in women who underwent breast reconstruction compared with those who did not. Conclusion: This study demonstrates a positive association between breast reconstruction and enhanced QOL in women undergoing breast cancer treatment and mastectomy. Patient-reported outcome measures using questionnaires, such as Breast-Q, can elucidate satisfaction levels with the reconstruction, which will likely improve continuously with advances in modern plastic surgery.

Living Flat: Stories from Women of Color After Mastectomy.

There remain persistent racial and ethnic disparities in the receipt of post-mastectomy breast reconstruction for breast cancer. Yet, patient-reported outcomes and advocacy efforts around living flat overwhelmingly have focused on white women. We sought to characterize the lived experiences among women of color living flat after mastectomy for breast cancer. Our community-partnered study included a sociodemographic and health questionnaire followed by semistructured interviews. Using an interview guide designed in an interdisciplinary manner, we explored themes related to culture and community after mastectomy. Women ≥ 18 years old who underwent mastectomy without reconstruction for breast cancer were included. Interviews were performed by formally trained community-based research fellows and conducted virtually over video conferencing, recorded, and transcribed. Data were analyzed on NVivo using an integrated (inductive and deductive) team-based approach. The final cohort included 20 women, 60% identified as Black, 20% as Asian, 10% as multiracial, 5% as Latina, and 5% as white. Key concepts included: (a) cancer stigma, (b) privacy around breasts, (c) finding support through shared experiences, (d) sacrifice of breast for life/health, (e) spirituality, (f) patients' familial roles and relationship to breast, and (g) societal expectations. Women described the intersection of cancer stigma and privacy around breasts influencing knowledge of family history and support during cancer treatment. Among women of color, breast cancer stigma and spirituality are key contributors to quality of life after mastectomy without breast reconstruction, domains not routinely included in contemporary patient-reported outcome measures. Representation of diverse experiences is critical to achieving equity.

Pregnancy-associated triple-negative breast cancer: A case report and literature review.

The incidence of pregnancy-associated breast cancer (PABC) is relatively low, but it has been increasing in recent years. The onset of PABC causes serious harm to the fetus and the mother due to the unique physiological characteristics of pregnancy, which poses a particular challenge to clinicians. This article reports a case of pregnancy-associated triple-negative breast cancer and describes the patient characteristics and systematic treatment of this type of breast cancer. A 33-year-old woman was admitted to hospital with a left breast mass that had appeared more than a year earlier. She was a second-time pregnant woman with a single live intrauterine fetus at 23 + 4 weeks of gestation. During the examination of the left breast, a 6 by 8 cm sized mass can be observed on the upper outer quadrant. Pregnancy-associated triple-negative breast cancer. The patient underwent a breast ultrasound which showed a left breast mass and the diagnosis was confirmed by a puncture biopsy of the left breast mass. The pregnancy was terminated after multidisciplinary discussion, taking into account the wishes of the patient and her family. After termination of the pregnancy, all treatments were given according to the standard triple-negative breast cancer (TNBC) treatment protocol. The patient was treated with neoadjuvant chemotherapy with epirubicin in combination with docetaxel (TE) in cycles of 21 days. After 3 cycles of TE, a modified radical mastectomy for left breast cancer was performed, and the appropriate radiotherapy and chemotherapy treatments were carried out in sequence. After the surgery, the disease-free survival for the patient was 3 months until local metastases were diagnosed. Thus the radiotherapy and chemotherapy were carried out, and then the patient was in good general condition with no recurrence or metastases. Clinicians need more research into the diagnosis, treatment and prognosis of PABC. Improving the rate of early diagnosis and using standardized and individualized comprehensive treatment plans will minimize fetal damage and improve survival and quality of life for patients.

Factors Predicting the Effect of a Complex Decongestive Therapy in Patients with Mild Lymphedema Following Mastectomy for Early Stage Breast Cancer.

Background: Complex decongestive therapy (CDT) is being used in breast cancer-related lymphedema (BCRL). The degree of initial edema and bioimpedance analysis (BIA) are known to be related with the therapeutic effect of CDT. D-dimer can indirectly reflect lymphangiogenesis because IL-6 regulates D-dimer and vascular endothelial growth factor, which is the most important lymphangiogenic factor. We assessed whether D-dimer could be used for the prediction of therapeutic effect of CDT, as well as BIA and initial edema. Methods: The participants were patients who took inpatient treatment for BCRL from July 2016 to May 2020. Percent excess volume (PEV) was calculated by dividing the difference in volume of both arms by the edema arm, and the difference in PEV before and after 2 weeks of CDT was defined as the CDT effect. BIA and D-dimer tests were performed before treatment. Results: The single frequency bioimpedance analysis (SFBIA) ratio and D-dimer showed significant correlations with β coefficients of 0.581 and 0.402 (p < 0.01), respectively, and the explanatory power of these models was confirmed to be 0.704.The areas under the curve of initial PEV, SFBIA ratio, D-dimer for determining the CDT effect were identified as 0.849, 0.795, and 0.725, respectively. Conclusions: Initial PEV, SFBIA ratio, and blood D-dimer levels could be used as predictors for CDT treatment effect. Their usefulness order was in the order of initial PEV, SFBIA ratio, and D-dimer. These factors could be used as predictors to establish therapeutic plan in patients with mild lymphedema.

Why do women with early breast cancer in Northern Sri Lanka undergo mastectomy? Decision-making and ways forward

BackgroundDespite robust evidence confirming equivalent survival rates and better cosmetic outcomes with breast-conserving surgery (BCS) and radiotherapy compared to mastectomy, the rates of mastectomy among women with early breast cancer have not declined significantly in Sri Lanka. This study explores views on the surgical treatment of breast cancer among Northern Sri Lankan women who were eligible for BCS but underwent mastectomy.MethodsAn exploratory descriptive qualitative study was carried out among 15 women who underwent mastectomy for early breast cancer. Patients who were referred to the Tellippalai Trail Cancer Hospital for adjuvant therapy after mastectomy and matched the study criteria were recruited. Data were collected through in-depth semi-structured interviews, which were transcribed in Tamil, translated into English, coded using QDA Miner Lite software, and analysed thematically.ResultsNine out of 15 participants were either not aware of breast-conserving surgery (BCS) as a treatment option or their eligibility for BCS at the time of mastectomy. According to participant narratives, the treating team had recommended mastectomy to most participants. While many opted for mastectomy believing that it was associated with lower rates of recurrence and spread compared to BCS, these beliefs were frequently reinforced by the treating team. The pros and cons of the two approaches had not been discussed before surgery with most participants. In the absence of information, family and friends weighed in on the decision to opt for mastectomy, ultimately resulting in feelings of loss and regret in most instances.ConclusionMost participants were not aware that they were eligible for BCS. These information gaps need to be urgently addressed for women to make informed decisions about their health.

Developing machine learning models for personalized treatment strategies in early breast cancer patients undergoing neoadjuvant systemic therapy based on SEER database

This study aimed to compare the long-term outcomes of breast-conserving surgery plus radiotherapy (BCS + RT) and mastectomy in early breast cancer (EBC) patients who received neoadjuvant systemic therapy (NST), and sought to construct and authenticate a machine learning algorithm that could assist healthcare professionals in formulating personalized treatment strategies for this patient population. We analyzed data from the Surveillance, Epidemiology, and End Results database on EBC patients undergoing BCS + RT or mastectomy post-NST (2010–2018). Employing propensity score matching (PSM) to minimize potential biases, we compared breast cancer-specific survival (BCSS) and overall survival (OS) between the two surgical groups. Additionally, we trained and validated six machine learning survival models and developed a cloud-based recommendation system for surgical treatment based on the optimal model. Among the 13,958 patients, 9028 (64.7%) underwent BCS + RT and 4930 (35.3%) underwent mastectomy. After PSM, there were 3715 patients in each group. Compared to mastectomy, BCS + RT significantly improved BCSS (p < 0.001) and OS (p < 0.001). Prognostic variables associated with BCSS were utilized to develop machine learning models. In both the training and validation cohorts, the random survival forest (RSF) model demonstrated superior predictive performance (0.847 and 0.795), not only outperforming other machine learning models, including Rpart (0.725 and 0.707), Xgboost (0.762 and 0.727), Glmboost (0.748 and 0.788), Survctree (0.764 and 0.766), and Survsvm (0.777 and 0.790), but also outperforming the classical COX model (0.749 and 0.782). Lastly, a web-based prediction tool was built to facilitate clinical application [https://jhren.shinyapps.io/shinyapp1]. After adjusting other confounders, BCS + RT was associated with improved outcomes in patients with EBC after NST, compared to those who underwent mastectomy. Moreover, the RSF model, a reliable tool, can predict long-term outcomes for patients, providing valuable guidance for operative methods and postoperative follow-up.

Immediate Breast Reconstruction After Mastectomy for Cancer Among US Military Health System Beneficiaries.

In the Military Health System (MHS), women with breast cancer may undergo surgical treatment in military hospitals (direct care) or in the civilian setting via the insurance benefit (private sector care). We conducted this study to determine immediate breast reconstruction rates among women undergoing mastectomy for cancer in the MHS by setting of care. Using the linked Department of Defense's Central Cancer Registry and MHS Data Repository, the Department of Defense's medical claims database, we identified adult women who underwent mastectomy for breast cancer from 1998 to 2014. Patients were then subgrouped by setting of care (direct vs private sector care). The primary outcome was the rate and type of immediate breast reconstruction. Regression models were constructed to determine factors associated with receipt of immediate breast reconstruction. The final sample included 3251 women who underwent mastectomy for cancer in the direct (67.0%) or private sector care (32.6%) settings. The overall rate of immediate breast reconstruction was 29.9% with an upward trend noted throughout the study (P < 0.001). Overall, implant-based reconstruction (81.4%) was more common than tissue-based reconstruction (18.6%). Compared with direct care, the immediate breast reconstruction rate was significantly higher in the private sector care setting (49.3% vs 20.5%, P < 0.001) despite accounting for differences in clinical characteristics (adjusted odds ratio = 4.51, 95% confidence interval [3.72-5.46]). Immediate breast reconstruction in the direct care setting lags that in the civilian community during the study time period. Further research is needed to ascertain current immediate reconstruction rates and understand factors contributing to any differences in rates between care settings.

ThP1.13 - Short term safety outcomes of immediate pre-pectoral implant based reconstruction

Abstract Aims In the UK up to 43% of women undergo immediate breast reconstruction (IBR) following mastectomy for breast cancer. Implant reconstruction is the commonest form of breast reconstruction and pre-pectoral techniques have been introduced with the aim of improving cosmetic outcome and avoiding animation. To assess the safety of pre-pectoral implant based breast reconstruction (PPBR), including infection rates, 30 day re-admission to hospital, need for unplanned surgery and implant loss at 3 months. Methods A retrospective study of 80 consecutive women who underwent PPBR for breast cancer or risk reduction between October 2020 and October 2023. Demographic, operative and complication data were collected. Results Eighty women (70 cancer, 8 risk reducing and 2 cancer/risk reducing) underwent 94 PPBR procedures (80 Skin sparing mastectomies and 14 Nipple and skin sparing mastectomies) with a mean age of 51.5 (range 28 to 79) years and a BMI of 25.2 kg/m2. 7 (8.8%) of women were smokers. The mean implant size used was 385cc (range 160cc to 650cc) with a mean breast weight of 448.6g (range 45g to 1700g). 10 (12.5%) women required oral antibiotics for wound infection with a further 2 (2.5%) women requiring re-admission within 30 days for IV antibiotics. 17 (21.3%) developed a seroma with 8 (47.1%) requiring drainage. No implant losses were recorded within 3 months of reconstruction. Conclusion We have demonstrated that PPBR is a good option for patients of a wide age range with a large variation in breast size with minimal complications and no implant losses.

Breast-conserving surgery versus modified radical mastectomy in T1-2N3M0 stage breast cancer: a propensity score matching analysis.

Breast-conserving surgery (BCS) plus radiotherapy and mastectomy exhibit highly comparable prognoses for early-stage breast cancer; however, the safety of BCS for T1-2N3M0 breast cancer remains unclear. This study compared long-term survival for BCS versus (vs.) modified radical mastectomy (MRM) among patients with T1-2N3M0 breast cancer. Data of patients with T1-2N3M0 breast cancer were extracted from the Surveillance, Epidemiology, and End Results database. Eligible patients were divided into 2 groups, BCS and MRM; Pearson's chi-squared test was used to estimate differences in clinicopathological features. Propensity score matching (PSM) was used to balance baseline characteristics. Univariate and multivariate analyses were performed to investigate the effects of surgical methods and other factors on breast cancer-specific survival (BCSS) and overall survival (OS). In total, 2124 patients were included; after PSM, 596 patients were allocated to each group. BCS exhibited the same 5-year BCSS (77.9% vs. 77.7%; P = 0.814) and OS (76.1% vs. 74.6%; P = 0.862) as MRM in the matched cohorts. Multivariate survival analysis revealed that BCS had the same BCSS and OS as MRM (hazard ratios [HR] 0.899 [95% confidence intervals (CI) 0.697-1.160], P = 0.413 and HR 0.858 [95% CI 0.675-1.089], P = 0.208, respectively); this was also seen in most subgroups. BCS demonstrated better BCSS (HR 0.558 [95% CI 0.335-0.929]; P = 0.025) and OS (HR 0.605 [95% CI 0.377-0.972]; P = 0.038) than MRM in those with the triple-negative subtype. BCS has the same long-term survival as MRM in T1-2N3M0 breast cancer and may be a better choice for triple-negative breast cancer.

Changes in Skin Paddle Morphology after Autologous Breast Reconstruction

Background: Immediate autologous breast reconstruction (IABR) can provide favorable aesthetic outcomes after skin-sparing mastectomy. However, it is known that the morphology of the reconstructed breast changes over time. Therefore, it is necessary to be able to predict the likely amount of change preoperatively to reconstruct a symmetrical breast. In this study, we retrospectively examined the change in position and morphology of the skin paddle of the reconstructed breast over time. Methods: Thirty-five patients who underwent IABR after skin-sparing mastectomy for unilateral breast cancer were included. Three-dimensional images were obtained at 1 month and 12 months postoperatively to compare changes in the position and size of the skin paddle over time. Results: Significant increases were observed in the distance between the center of the skin paddle and the midpoint of the clavicle, the distance between the center of the skin paddle and the sternal notch, and projection. No significant change was observed in the distance between the inframammary fold and the center of the skin paddle. There was a significant increase in the area and short axis of the skin paddle. Conclusions: Our main findings were that the skin paddle shifts toward the outer caudal side after IABR and tends to become larger. When planning delayed nipple reconstruction with a local flap designed on a skin paddle, the paddle should be positioned slightly more mediocranially than the healthy nipple and should be narrower.

Tremendous and infrequently adenoid cystic carcinoma of the breast without any metastasis for more than 20 years: A case report.

Breast adenoid cystic carcinoma is an extremely rare tumor that is incompletely understood, accounting for less than <0.1% of all breast cancers, with an average diameter of 3 cm, and it is extremely rare to see a large, non-metastatic breast adenoid cystic carcinoma with a diameter of about 30 cm. Since this disease is extremely rare, there are few reports in the literature and limited data on clinical diagnosis and treatment. We present a case of a 71-year-old woman with a large, non-metastatic adenoid cystic carcinoma of the left breast and share our opinion on the diagnosis and treatment of this case. A 71-year-old woman with a 20-year-old left breast mass with local bleeding and rupture for 1 hour presented to our hospital for further diagnosis and treatment. A computed tomography scan showed a large soft tissue mass shadow in the left breast and malignancy was considered. Subsequently, tissue aspiration pathology was performed and the results confirmed adenoid cystic carcinoma of the breast. Intraoperative pathology results of radical mastectomy for left breast cancer diagnosed adenoid cystic carcinoma of the breast and immunohistochemistry results of triple-negative breast cancer. Treatment of adenoid cystic carcinoma of the breast included neoadjuvant chemotherapy for breast cancer, radical mastectomy of the left breast, and postoperative chemotherapy. Initially, neoadjuvant chemotherapy for breast cancer was performed, and the TAC regimen was used to successfully reduce the size of the tumor and gain access to surgical treatment for breast cancer. The patient has recovered well after the surgery, with no wound infection or ulceration, and is now waiting for the patient's physical function to recover for postoperative chemotherapy, with no obvious discomfort. Adenoid cystic carcinoma tumors are usually around 3 cm; such a huge 30 cm adenoid cystic carcinoma of the breast is extremely rare, and it is extremely rare to find a breast malignancy that has not developed regional lymph node and distant metastases for more than 20 years. Clinicians must remain vigilant for early breast malignancies at a high age of incidence and conduct further research for diagnosis to avoid delays.

Surgical and irradiated case of early breast cancer in a patient with Ehlers–Danlos syndrome

BackgroundEhlers–Danlos syndrome (EDS) is a rare inherited connective tissue disease characterized by hyperextensibility of the skin and joints and tissue fragility of the skin and blood vessels, Vascular EDS is the most severe form of EDS, with abnormal arterial fragility. There have been no reports of breast cancer occurring in patients with vascular EDS. Here, we report here a very rare case of breast cancer in a patient with vascular EDS.Case presentationA 46-year-old woman with vascular EDS underwent partial left mastectomy and sentinel lymph node biopsy for left breast cancer (cStage 0) detected by medical examination. The final pathological diagnosis was invasive ductal carcinoma of the breast (pStage IA) [hormone receptor-positive, HER2 score 2 equivocal (FISH-positive), Ki-67LI 18%, luminal-HER2 type]. BluePrint was submitted as an aid in determining the postoperative treatment strategy, BluePrint Molecular Subtype HER2-type. However, the 10-year breast cancer mortality risk using Predict was low (5%). After consultation with the patient, the decision was made to administer postoperative radiation to the preserved breast along with hormone therapy only. There was no delay in postoperative wound healing, and the patient was free of metastatic recurrence for 9 months after surgery.ConclusionWe performed surgery, postoperative radiotherapy, and hormonal therapy in a breast cancer patient with vascular EDS without major complications.

Minimal Access vs Conventional Nipple-Sparing Mastectomy

While nipple-sparing mastectomy (NSM) for breast cancer was only performed using the open method in the past, its frequency using endoscopic and robotic surgical instruments has been increasing rapidly. However, there are limited studies regarding postoperative complications and the benefits and drawbacks of minimal access NSM (M-NSM) compared with conventional NSM (C-NSM). To examine the differences in postoperative complications between C-NSM and M-NSM. This was a retrospective multicenter cohort study enrolling 1583 female patients aged 19 years and older with breast cancer who underwent NSM at 21 university hospitals in Korea between January 2018 and December 2020. Those with mastectomy without preserving the nipple-areolar complex (NAC), clinical or pathological malignancy in the NAC, inflammatory breast cancer, breast cancer infiltrating the chest wall or skin, metastatic breast cancer, or insufficient medical records were excluded. Data were analyzed from November 2021 to March 2024. M-NSM or C-NSM. Clinicopathological factors and postoperative complications within 3 months of surgery were assessed. Statistical analyses, including logistic regression, were used to identify the factors associated with complications. There were 1356 individuals (mean [SD] age, 45.47 [8.56] years) undergoing C-NSM and 227 (mean [SD] age, 45.41 [7.99] years) undergoing M-NSM (35 endoscopy assisted and 192 robot assisted). There was no significant difference between the 2 groups regarding short- and long-term postoperative complications (<30 days: C-NSM, 465 of 1356 [34.29%] vs M-NSM, 73 of 227 [32.16%]; P = .53; <90 days: C-NSM, 525 of 1356 [38.72%] vs M-NSM, 73 of 227 [32.16%]; P = .06). Nipple-areolar complex necrosis was more common in the long term after C-NSM than M-NSM (C-NSM, 91 of 1356 [6.71%] vs M-NSM, 5 of 227 [2.20%]; P = .04). Wound infection occurred more frequently after M-NSM (C-NSM, 58 of 1356 [4.28%] vs M-NSM, 18 of 227 [7.93%]; P = .03). Postoperative seroma occurred more frequently after C-NSM (C-NSM, 193 of 1356 [14.23%] vs M-NSM, 21 of 227 [9.25%]; P = .04). Mild or severe breast ptosis was a significant risk factor for nipple or areolar necrosis (odds ratio [OR], 4.75; 95% CI, 1.66-13.60; P = .004 and OR, 8.78; 95% CI, 1.88-41.02; P = .006, respectively). Conversely, use of a midaxillary, anterior axillary, or axillary incision was associated with a lower risk of necrosis (OR for other incisions, 32.72; 95% CI, 2.11-508.36; P = .01). Necrosis occurred significantly less often in direct-to-implant breast reconstruction compared to other breast reconstructions (OR, 2.85; 95% CI, 1.11-7.34; P = .03). The similar complication rates between C-NSM and M-NSM demonstrates that both methods were equally safe, allowing the choice to be guided by patient preferences and specific needs.

Can contralateral prophylactic mastectomy and oophorectomy increase survival in BRCA-related breast cancer? Results from the Italian MUTina study

IntroductionIn the Emilia-Romagna region of Italy, a unique Hub and Spoke model was adopted to recognize BRCA-related breast cancer (BC) patients. Characteristics and outcomes of tumors identified by this model will be presented. MethodsThis multicenter retrospective cohort study involved patients diagnosed with BRCA-related BC identified in the Emilia-Romagna region between January 2000 and December 2013. Seven provinces collected data on patient and tumor characteristics; clinical and gene testing information were also registered. Comparisons between BRCA1 and BRCA2 BC were performed. To balance different variants to identify significant predictors of survival, an inverse probability of treatment weighting (IPTW) analysis on Cox regression was conducted. ResultsFrom 2000 to 2013, 284 BRCA-related BC were registered (171 BRCA1, 110 BRCA2, and 3 BRCA1 and BRCA2). BRCA1 were diagnosed at an earlier stage compared to BRCA2 (50.1 % vs 30 %, respectively, in stage I, P = 0.0015). BRCA2 patients underwent more up-front surgery (85 % vs. 74.9 %, P = 0.049) and less chemotherapy (69.1 % vs 88.9 %, P = 0.004) than BRCA1 patients. At 11.8 years median follow-up, BRCA1 patients developed more second contralateral BC (P = 0.09), while BRCA2 had more visceral relapses (P = 0.013). No differences in overall survival (OS) between BRCA1 and BRCA2 patients (P = 0.07) were found. An advantage in OS was independently seen for patients who underwent contralateral prophylactic mastectomy (P = 0.0001) and oophorectomy (P < 0.0001). ConclusionsIn conclusion, adopting a homogeneous regional framework provides important information about prevention and treatment strategies of BRCA-related BC and suggests using maximal surgery to improve OS.

Efficacy of Ultrasound-Guided Intercostal Nerve Block on Pain Management and Physiological Outcomes in Breast Cancer Mastectomy: A retrospective study.

To evaluate the efficacy of ultrasound-guided intercostal nerve block in managing pain and physiological responses in patients undergoing radical mastectomy for breast cancer. A retrospective study analyzed 120 patients scheduled to undergo radical mastectomy in our hospital between January 2022 and December 2023. Depending on the type of anesthesia received, participants were assigned to the experimental group (60 patients) to receive ultrasound-guided intercostal nerve block and intravenous general anesthesia, or the control group (60 patients) to receive intravenous general anesthesia only. Both groups will utilize patient-controlled intravenous analgesia (PCIA) postoperatively. We will monitor and compare hemodynamic parameters, SpO2, and bispectral index (BIS) at multiple time points, and assess postoperative pain, inflammatory markers, PCIA utilization, and adverse reaction incidence. Comparative analysis showed distinct trends in heart rate, mean arterial pressure (MAP), BIS, and SpO2 across various surgical stages between groups. Notably, MAP values were consistently higher and less variable in the experimental group during surgery (P < .05). Pain assessments at 4, 12, and 24 hours postoperatively in both quiet and coughing states revealed significantly milder pain in the experimental group (P < .05). Preoperative inflammatory markers (PGE2, TNF-α, IL-6, MCP-1) were similar between groups; however, 24 hours post-surgery, the experimental group showed significantly lower levels of PGE2, IL-6, and MCP-1 (P < .05). Sufentanil consumption during surgery and PCIA use were notably lower in the experimental group (P < .05). The experimental group also experienced fewer anesthesia-related adverse reactions (8.33%) compared to the control group (25.00%) (P < .05). Ultrasound-guided intercostal nerve block significantly improves hemodynamic stability, reduces postoperative inflammatory markers, lowers the need for sufentanil, and minimizes adverse reactions in patients undergoing radical mastectomy for breast cancer.
