Aspirin Use Is Associated With Improved Outcomes in Inflammatory Breast Cancer Patients.

PURPOSE: Inflammatory breast cancer (IBC) is the most aggressive form of breast cancer and has a high propensity for distant metastases. Our previous data suggested that aspirin (acetylsalicylic acid, ASA) use may be associated with reduced risk of distant metastases in aggressive breast cancer; however, there are no reported studies on the potential benefit of ASA use in patients with IBC. METHODS: Data from patients with non-metastatic IBC treated between 2000-2017 at two institutions, were reviewed. Overall survival (OS), disease-free survival (DFS), and distant metastasis-free survival (DMFS) were performed using Kaplan-Meier analysis. Univariate and multivariable logistic regression models were used to identify significant associated factors. RESULTS: Of 59 patients meeting the criteria for analysis and available for review, 14 ASA users were identified. ASA users demonstrated increased OS (p = 0.03) and DMFS (p = 0.02), with 5-year OS and DMFS of 92% (p = 0.01) and 85% (p = 0.01) compared to 51% and 43%, respectively, for non-ASA users. In univariate analysis, pT stage, pN stage, and ASA use were significantly correlated (p < 0.05) with OS and DFS. On multivariable analysis, ASA use (hazard ratio [HR], 0.11; 95% confidence interval [CI], 0.01-0.8) and lymph node stage (HR, 5.9; 95% CI, 1.4-25.9) remained significant for OS and DFS ASA use (HR, 0.13; 95% CI, 0.03-0.56) and lymph node stage (HR, 5.6; 95% CI, 1.9-16.4). CONCLUSION: ASA use during remission was associated with significantly improved OS and DMFS in patients with IBC. These results suggest that ASA may provide survival benefits to patients with IBC. Prospective clinical trials of ASA use in patients with high-risk IBC in remission should be considered.

A New N-staging System for Predicting Postoperative Survival of M0 Stage Inflammatory Breast Cancer / 肿瘤防治研究

Objective To establish a new N-stage system combining the number of metastatic lymph nodes and the ratio of metastatic lymph nodes for postoperative M0 stage inflammatory breast cancer patients. Methods Based on the data of inflammatory breast cancer patients in the SEER database, the number of metastatic lymph nodes and the ratio of metastatic lymph nodes were calculated.A new N-staging system was established and compared with the 8th edition of AJCC TNM staging system of breast cancer.The nomograph prognostic model was constructed and validated. Results The prediction performance of the new N-staging system for postoperative survival of M0 inflammatory breast cancer patients was better than the traditional N-staging system.The nomograph prognostic model showed an excellent clinical efficacy with a consistency index of 0.711. Conclusion The new N-staging system has good predictive performance for postoperative survival of M0 inflammatory breast cancer patients and can accurately reflect the prognosis.

Changes in Overall Survival over Time for Patients with de novo Metastatic Breast Cancer.

The purpose of this study was to determine the change in overall survival (OS) for patients with de novo metastatic breast cancer (dnMBC) over time. We conducted a retrospective cohort study with 1981 patients with dnMBC diagnosed between January 1995 and December 2017 at The University of Texas MD Anderson Cancer Center. OS was measured from the date of diagnosis of dnMBC. OS was compared between patients diagnosed during different time periods: 5-year periods and periods defined according to when key agents were approved for clinical use. The median OS was 3.4 years. The 5- and 10-year OS rates improved over time across both types of time periods. A subgroup analysis showed that OS improved significantly over time for the estrogen-receptor-positive/HER2-positive (ER+/HER2+) subtype and exhibited a tendency toward improvement over time for the ER-negative (ER-)/HER2+ subtype. In addition, median OS was significantly longer in patients with non-inflammatory breast cancer (p = 0.02) and patients with ER+ disease, progesterone-receptor-positive disease, HER2+ disease, lower nuclear grade, locoregional therapy, and metastasis to a single organ (all p < 0.0001). These findings showed that OS at 5 and 10 years after diagnosis in patients with dnMBC improved over time. The significant improvements in OS over time for the ER+/HER2+ subtype and the tendency toward improvement for the ER-/HER2+ subtype suggest the contribution of HER2-targeted therapy to survival.

A novel CD74-ROS1 gene fusion in a patient with inflammatory breast cancer: a case report.

BACKGROUND: CD74-ROS1 fusion genes have been detected in non-small cell lung carcinomas (NSCLC), but not in inflammatory breast cancer. CASE PRESENTATION: Herein, we report a CD74-ROS1 fusion gene identified in a 64-year-old Chinese woman with inflammatory breast cancer (IBC). The patient initially presented with a rapidly growing mass in the left breast with diffuse erythema developing over a period of 2 months. Diagnosis of invasive breast carcinoma was made by core needle biopsy. Positron emission tomography-computed tomography (PET/CT) demonstrated multiple organ metastases. Genomic DNA was extracted from tumor tissue and analyzed using next-generation sequencing (NGS). The CD74-ROS1 fusion gene was detected in the genomic DNA. The patient refused crizotinib treatment, and could not tolerate the side effects of palliative chemotherapy. Unfortunately, the patient died 4 months after diagnosis. CONCLUSION: We report the case of a CD74-ROS1 fusion gene in a patient with IBC. This may reveal, for the first time, a possible association between CD74-ROS1 gene fusion and rapid progression of inflammatory breast cancer. Multigene panel testing can be performed when rapidly progressive breast cancer occurs and could reveal potential therapeutic strategies.

Biomarkers for Inflammatory Breast Cancer: Diagnostic and Therapeutic Utility.

Inflammatory breast cancer (IBC) is a rare and highly aggressive subtype of advanced breast cancer. The aggressive behavior, resistance to chemotherapy, angiogenesis, and high metastatic potential are key intrinsic characteristics of IBC caused by many specific factors. Pathogenesis and behavior of IBC are closely related to tumor surrounding inflammatory and immune cells, blood vessels, and extracellular matrix, which are all components of the tumor microenvironment (TME). The tumor microenvironment has a crucial role in the local immune r09esponse. The communication between intrinsic and extrinsic components of IBC and the abundance of cytokines and chemokines in the TME strongly contribute to the aggressiveness and high angiogenic potential of this tumor. Critical modes of interaction are cytokine-mediated communication and direct intercellular contact between cancer cells and tumor microenvironment with a variety of pathway crosstalk. This review aimed to summarize current knowledge of predictive and prognostic biomarkers in IBC.

ABSTRACT Background: triple negative breast cancer constitutes a public health problem due to its high morbidity and mortality. Objective: to characterize the patients diagnosed with triple negative breast cancer treated at the Oncology Service of the Celestino Hernández Robau University Hospital in the period 2015-2016. Method: a descriptive cross-sectional study was carried out. The universe corresponded to 59 patients diagnosed with histological confirmed triple negative breast cancer. The variables were considered: age, skin color, histological variant, tumor size, lymph node status, vascular and lymphatic invasion, histological grade and clinical nucleo-stages, treatment, type and time of appearance of metastases. The information collected was processed through the statistical program IBM SPSS version 21. The frequency and percentage distributions were used from descriptive statistics. The results were expressed by charts. Results: the predominant age group was 60 and over, white skin color, the most frequent histological diagnosis was infiltrating ductal carcinoma, clinical stage II prevailed, there was no involvement of axillary lymph nodes or vascular and lymphatic invasion, the diagnosed metastases that the visceral ones predominated. Conclusions: the age of 60 years and older prevailed and infiltrating ductal carcinoma, tumor size, histological grade and nuclear grade are important prognostic factors for the diagnosis and treatment of triple negative breast cancer. At the end of the study, the 55,9 % of the patients were alive.

Quantitative hormone receptor (HR) expression and gene expression analysis in HR+ inflammatory breast cancer (IBC) vs non-IBC.

BACKGROUND: The purpose of this study was to determine the prognostic role of hormone receptor (HR) on inflammatory breast cancer (IBC) to elucidate its aggressive biological behavior. METHODS: We evaluated the expression of estrogen receptor (ER) and progesterone receptor (PR) by immunohistochemical staining and determined the predictive and prognostic role of HR expression on 189 patients with HR+/HER2- IBC and 677 patients with HR+/HER2- stage III non-IBC. Furthermore, we performed gene expression (GE) analyses on 137 patients with HR+/HER2- IBC and 252 patients with HR+/HER2- non-IBC to detect genes that are specifically overexpressed in IBC. RESULTS: The expression of ER% was significantly associated with longer distant disease-free survival and overall survival. However, there was no significant relationship between ER% and neoadjuvant chemotherapy outcome. In the GE study, 84 genes were identified as significantly distinguishing HR+ IBC from non-IBC. Among the top 15 canonical pathways expressed in IBC, the ERK/MAPK, PDGF, insulin receptor, and IL-7 signaling pathways were associated with the ER signaling pathway. Upregulation of the MYC gene was observed in three of these four pathways. Furthermore, HR+/HER2- IBC had significantly higher MYC amplification, and the genetic alteration was associated with poor survival outcome. CONCLUSIONS: Higher ER expression was significantly associated with improved survival in both HR+/HER2- IBC and HR+/HER2- stage III non-IBC patients. HR+/HER2- IBC had several activated pathways with MYC upregulation, and the genetic alteration was associated with poor survival outcome. The results indicate that MYC may be a key gene for understanding the biology of HR+/HER2- IBC.

Prognostic Value of HER2 to CEP17 Ratio on Fluorescence In Situ Hybridization Ratio in Patients with Nonmetastatic HER2-Positive Inflammatory and Noninflammatory Breast Cancer Treated with Neoadjuvant Chemotherapy with or without Trastuzumab.

BACKGROUND: We previously reported that in patients with HER2-positive (HER2+) locally advanced breast cancer treated with neoadjuvant trastuzumab-containing regimens, high HER2 to centromere enumerator probe 17 ratio on fluorescence in situ hybridization (HER2 FISH ratio) was an independent predictor of high pathologic complete response (pCR) rate, which translated into improved recurrence-free survival (RFS). We sought to determine whether high HER2 FISH ratio is a predictor of pCR and prognosis in patients with HER2+ nonmetastatic inflammatory breast cancer (IBC) and non-IBC treated with neoadjuvant chemotherapy with or without trastuzumab. MATERIALS AND METHODS: This study included all patients with histologically proven stage III, HER2+ primary IBC, and non-IBC treated with neoadjuvant chemotherapy with or without trastuzumab and definitive surgery during 1999-2012. Univariate and multivariate logistic regression models were applied to assess the effect of covariates on pCR. Kaplan-Meier estimates with log-rank test were employed for survival analysis. Univariate and multivariate Cox proportional hazards models were used to assess the effect of covariates on RFS and overall survival (OS). RESULTS: The study included 555 patients with stage III, HER+ breast cancer, 181 patients with IBC, and 374 with non-IBC. In the IBC cohort, HER2 FISH ratio was not significantly associated with pCR, RFS, or OS. In the non-IBC cohort, higher HER2 FISH ratio was significantly associated with higher pCR rate and longer OS. CONCLUSION: HER2 FISH ratio showed prognostic value among patients with HER2+ non-IBC but not HER2+ IBC treated with neoadjuvant chemotherapy. This disparity may be due to the underlying aggressive nature of IBC. IMPLICATIONS FOR PRACTICE: The findings of this study indicate that the HER2 to fluorescence in situ hybridization ratio as a continuous variable has promise as a predictor of pathologic complete response to neoadjuvant chemotherapy in patients with HER2-positive (HER2+) noninflammatory breast cancer (non-IBC) regardless of the results on HER2 immunohistochemical testing. In the future, some patients with HER2+ non-IBC and a high HER2 FISH ratio might even be offered personalized treatment options, such as nonsurgical treatment.

Single vertical incision thoracoabdominal flap for chest wall reconstruction following mastectomy of locally advanced breast cancer.

PURPOSE: Skin grafts have been widely used in managing extensive chest wall defects after mastectomy for advanced breast cancer. However, their durability and tolerability to radiotherapy is still controversial. A thoracoabdominal (TA) flap with a few technical refinements can safely transfer a larger flap while minimizing complications. METHODS: From January 2007 to February 2018, a retrospective review was performed to compare 2 groups after wide breast excision: skin graft group (group 1) and lateral-based, single vertical incision rotation-advancement TA flap (group 2). Patients' demographics, operative details, complications, hospital stay, postoperative outpatient visits, cost, and start of adjuvant therapy were analyzed between the 2 groups. RESULTS: During the study period, 34 patients received skin graft and 41 patients received TA flap. group 2 had a shorter hospital stay (6.41 ± 2.64 days vs. 12.62 ± 4.60 days, P < 0.001) and shorter time to complete wound healing (29.27 ± 18.68 days vs. 39.24 ± 27.70 days, P = 0.03) than group 1. There was also a difference in the period from surgery to initiation of adjuvant therapy (group 1, 45.04 days ± 17.79 days; group 2, 37.07 ± 15.38 days, P = 0.073). Although limitation in shoulder motion was more frequent in group 2, limitation of motion for >1 year was observed in 4 patients in only group 1 (43.90% vs. 38.24%, P = 0.613). CONCLUSION: TA flap has a simple design that minimizes concerns involving the donor site. Moreover, it does not require complicated procedures and allows for re-elevation whenever necessary. Finally, it guarantees faster wound recovery than skin graft with fewer complications.

Percepção dos internos de uma faculdade de medicina sobre o câncer de mama e reconstrução mamária / Perception of breast cancer and breast reconstruction in medical school students

Introdução: O câncer de mama é o tipo mais comum entre as mulheres no mundo e no Brasil, depois do câncer de pele não melanoma. O objetivo é avaliar a percepção dos estudantes de medicina sobre o câncer de mama e reconstrução mamária. Métodos: Trata-se de estudo transversal piloto composto por alunos do 5º e 6º ano de curso de medicina, realizado de maio de 2016. Resultados: Foi questionado se há possibilidade de reconstrução mamária após a mastectomia, sendo que de forma unânime 100% foi sim. Para melhor caracterização, foi perguntado se a reconstrução pode ser feita no mesmo momento da mastectomia, 69 (57,5%) estudantes marcaram sim e 51 (42,5%) negaram. Em análise aos conhecimentos cirúrgicos, foi perguntado se os mesmos conhecem alguma técnica de reconstrução mamária, sendo que 49 (40,83%) responderam que sim e 71 (59,16%) negaram conhecer. Em relação ao encaminhamento à especialidade médica mais preparada para acompanhar e realizar a reconstrução mamária, 93 (77,5%) discentes elegeram a cirurgia plástica e 26 (21,66%) a mastologia. Quanto à possibilidade de reconstrução de mama em pacientes que farão radioterapia adjuvante, 66 (55%) responderam sim, 51 (42,5%) não e 3 (2,5%) não souberam responder. Quanto a esta possibilidade mesmo em pacientes com implantes de silicone, 59 (49,16%) responderam sim, 3 (2,5%) responderam não e 58 (48,33%) afirmaram não saber sobre o assunto. Conclusão: Observou-se que a Mastologia vem ganhando espaço na reconstrução de mama, inclusive no meio acadêmico, devido ao alto percentual de resposta de que a mesma seria mais preparada do que a Cirurgia Plástica para reconstrução mamária.

Introduction: Breast cancer is the most common type of cancer among women in the world and in Brazil, after non-melanoma skin cancer. Our objective was to evaluate the medical students' perception of breast cancer and breast reconstruction. Methods: This is a cross-sectional pilot study composed of students from the fifth and sixth year of medical school, in May 2016. Results: We questioned whether there is a possibility of breast reconstruction after mastectomy, and the response was unanimous (100%). For a better characterization, we asked if the reconstruction could be done at the same time as the mastectomy, and 69 (57.5%) students said yes and 51 (42.5%) denied. In the analysis of surgical knowledge, we asked whether they knew any breast reconstruction technique, and 49 (40.83%) answered yes and 71 (59.16%) denied knowing. With regard to referral to a medical specialist who was better prepared to follow and perform breast reconstruction, 93 (77.5%) students chose plastic surgery and 26 (21.66%) chose mastology. Regarding the possibility of breast reconstruction in patients who need to undergo adjuvant radiotherapy, 66 (55%) answered yes, 51 (42.5%) did not answer, and three (2.5%) did not know how to respond. Regarding this possibility in patients with silicone implants, 59 (49.16%) answered yes, three (2.5%) answered no, and 58 (48.33%) said they did not know about the subject. Conclusion: We conclude that mastology has been gaining immense interest in the field of breast reconstruction, including in the academic world, based on the high percentage of respondents who stated that they are better prepared for this procedure than for plastic surgery for breast reconstruction.

Immediate breast reconstruction for women having inflammatory breast cancer in the United States.

Inflammatory breast cancer (IBC) is an aggressive malignancy having a poor prognosis. Traditionally, reconstruction is not offered due to concerns about treatment delay, margin positivity, recurrence, and poor long-term survival. There is a paucity of literature, however, evaluating whether immediate breast reconstruction (IBR) is associated with greater mortality in patients with IBC. A population-based study was conducted via the SEER-Medicare-linked database (1991-2009). Female patients greater than 65 years were reviewed who had mastectomy and reconstruction claims for nonmetastatic IBC. Competing risk and Cox regression were used to assess whether IBR was associated with higher breast cancer-specific mortality (BCSM) or overall mortality (OM). Among 552 936 patients, 1472 (median age 74 years) were diagnosed with IBC and had a mastectomy. Forty-four patients (3%) underwent IBR. Younger age, a lower Charlson comorbidity score, and a greater median income were predictors of IBR use. Tumor grade, hormone receptor status, and lymph node status were independent predictors of adjusted OM and BCSM. There was no difference by IBR status in BCSM or covariate-adjusted BCSM (sHR 1.04; CI 0.71-1.54; P = .83 and sHR 1.13; CI 0.84-1.93; P = .58, respectively). Cumulative incidence of OM was lower among IR patients (P = .013), and IR did not influence the cumulative incidence of BCSM (P = .91). IBR was not associated with increased overall and BCSM mortality. Although further study of IBR in the IBC setting may be of value, these data suggest that IBC should not be considered an absolute contraindication to IBR.

Dermoscopy of inflammatory breast cancer

Abstract: Inflammatory breast cancer is an aggressive and infiltrative malignancy that is often misdiagnosed as an infection because of its symptoms and signs of inflammation, delaying proper diagnosis and treatment. We report a case of inflammatory breast cancer showing correlation between dermoscopic and histopathological diagnoses. We highlight the utility of dermoscopy for skin biopsy site selection.

BRCA mutations in women with inflammatory breast cancer.

BACKGROUND: Inflammatory breast cancer (IBC) often affects women at a relatively young age. To the authors' knowledge, the rate of BRCA variants among patients with IBC is not known. To determine the association between BRCA status and IBC, the authors evaluated its rate and compared the clinicopathologic characteristics of patients with IBC with those of patients with other breast cancers (non-IBC). METHODS: Patients who presented at the study institution's cancer genetics program and who underwent BRCA genetic testing were included in the current study. The authors compared clinicopathologic data between patients with IBC and those with non-IBC using propensity score matching to identify predictors. RESULTS: A total of 1789 patients who underwent BRCA genetic testing (1684 with non-IBC and 105 with IBC) were included. BRCA pathogenic variants were found in 27.3% of patients with non-IBC and 18.1% of patients with IBC (P = .0384). After propensity score matching, there were no significant differences noted between patients with IBC and those with non-IBC, including the rate of BRCA pathogenic variants (P = .5485). However, a subgroup analysis of the 479 patients with BRCA pathogenic variants demonstrated that patients with IBC (19 patients) were diagnosed at significantly younger ages compared with patients with non-IBC (P = .0244). CONCLUSIONS: There was no clear association observed between BRCA pathogenic variants and IBC. However, among patients who tested positive for BRCA pathogenic variants, those with IBC were younger at the time of diagnosis compared with those with non-IBC breast cancers. These results confirm that genetic testing is important for patients with IBC who meet the current clinical criteria for genetic testing in breast cancer.

Inflammatory breast cancer: high incidence of detection of mixed human cytomegalovirus genotypes associated with disease pathogenesis.

Inflammatory breast cancer (IBC) is a highly metastatic, aggressive, and fatal form of breast cancer. Patients presenting with IBC are characterized by a high number of axillary lymph node metastases. Recently, we found that IBC carcinoma tissues contain significantly higher levels of human cytomegalovirus (HCMV) DNA compared to other breast cancer tissues that may regulate cell signaling pathways. In fact, HCMV pathogenesis and clinical outcome can be statistically associated with multiple HCMV genotypes within IBC. Thus, in the present study, we established the incidence and types of HCMV genotypes present in carcinoma tissues of infected non-IBC versus IBC patients. We also assessed the correlation between detection of mixed genotypes of HCMV and disease progression. Genotyping of HCMV in carcinoma tissues revealed that glycoprotein B (gB)-1 and glycoprotein N (gN)-1 were the most prevalent HCMV genotypes in both non-IBC and IBC patients with no significant difference between patients groups. IBC carcinoma tissues, however, showed statistically significant higher incidence of detection of the gN-3b genotype compared to non-IBC patients. The incidence of detection of mixed genotypes of gB showed that gB-1 + gB-3 was statistically significantly higher in IBC than non-IBC patients. Similarly, the incidence of detection of mixed genotypes of gN showed that gN-1 + gN-3b and gN-3 + gN-4b/c were statistically significant higher in the carcinoma tissues of IBC than non-IBC. Mixed presence of different HCMV genotypes was found to be significantly correlated with the number of metastatic lymph nodes in non-IBC but not in IBC patients. In IBC, detection of mixed HCMV different genotypes significantly correlates with lymphovascular invasion and formation of dermal lymphatic emboli, which was not found in non-IBC patients.

Alternative medicine for management of breast masses: more harm than good.

UNLABELLED: CASE SERIES. PATIENT: -. FINAL DIAGNOSIS: Breast cancer. SYMPTOMS: -. MEDICATION: -. CLINICAL PROCEDURE: - SPECIALTY: -. OBJECTIVE: Diagnostic/therapeutic accidents. BACKGROUND: Several well-established, evidence-based treatment modalities are currently available and widely applied to breast cancer patients, but it is known that some of the cancer patients use traditional/alternative medicine other than their treatments. CASE REPORT: Herein, we report the cases of 2 middle-aged women (45 and 50 years old) with malignant breast masses who experienced serious complications in response to self-prescribed use of alternative medicine practices to treat their condition in lieu of evidence-based medical treatment. Specifically, the use and/or inappropriate application of alternative medical approaches promoted the progression of malignant fungating lesions in the breast for these 2 patients. The first patient sought medical assistance upon development of a fungating lesion 7∼8 cm in diameter and involving 1/3 of the breast, with a palpable mass of 5×6 cm immediately beneath the wound. The second patient sought medical assistance upon development of a wide, bleeding, ulcerous area with patchy necrotic tissue that comprised 2/3 of the breast and had a 10×6 cm palpable mass under the affected area. Use of some non-evidence-based medical treatments as complementary to evidence-based medical treatments may benefit the patient on an emotional level; however, this strategy should be used with caution, as the non-evidence-based therapies may cause physical harm or even counteract the evidence-based treatment. CONCLUSIONS: A malignant, fungating wound is a serious complication of advanced breast cancer. It is critical that the public is informed about the potential problems of self-treating wounds such as breast ulcers and masses. Additionally, campaigns are needed to increase awareness of the risks and life-threatening potential of using non-evidence-based medical therapies exclusively.

Inflammatory breast neoplasms: a systematic review

OVERVIEW: Inflammatory Breast Cancer (IBC) is a rare and very aggressive type of cancer that tends to develop at a younger age, compared with other subtypes of breast cancer. Because a distinct lump may not be noticeable, correct diagnosis takes longer and, therefore, successful treatment may hinder a patient's prognostics. This study aims to conduct a systematic review of research articles on IBC. METHODS: This is a systematic review of studies in the PubMed database to April 2013, which fit the eligibility criterion of "Inflammatory Breast Neoplasms" (MeSH Terms), filtered by Languages (English OR Portuguese OR Spanish). FINDINGS: Of the 119studies identified, 25 complied with the eligibility criterion for the disease, diagnostics, treatment and prognostics. FINAL CONSIDERATIONS: Despite methodological differences, findings evidence that although IBC presents particular features (lower survival rate and worse prognostics than most types of breast cancer), very few studies examine its epidemiology and specific risk factors in depth and use any other therapeutic approaches than those commonly used for other breast cancer subtypes. Therefore, further investigation of the disease's aggressiveness is still necessary.
