Breast Cancer Phenotype Influences MRI Response Evaluation after Neoadjuvant Chemotherapy

ConclusionsMRI demonstrated good accuracy in predicting pCR after NAC among the breast cancer patients examined. However, non-mass enhancement at pre-treatment MRI negatively affected the diagnostic performance of MRI in assessing treatment response after NAC.

ConclusionsIn patients with TNBC-NST, intra-E and intra-N did not correlate with pCR, but intra-E did positively correlate with tumor size. NST may exhibit a greater response to NAC, regardless of whether intra-E or intra-N is present or not on the pretreatment MRI.Key Points• Pathological complete response in TNBC-NST had no correlation with intramammary edema or intratumoral necrosis.• NAC may be justified in TNBC-NST even in the presence of edema or necrosis.• The extension of edema correlated with tumor size of TNBC-NST.

Abstract BACKGROUND: Triple-negative breast cancer encompasses heterogeneous subtypes. Neoadjuvant chemotherapy is ineffective against some triple-negative breast cancers, while others show a favorable prognosis despite chemoresistance. METHODS: A total of 51 cases with stages I and II triple-negative breast cancer were analyzed; 34 triple-negative breast cancers treated with neoadjuvant chemotherapy were divided into "good responders" (n = 22), showing therapeutic effect G2b or G3 in surgical specimens, and "poor responders" with therapeutic effect G0, G1a, G1b, and G2a (n = 12). Neoadjuv...

Conclusion: The texture analysis for breast DCE-MRI proposed in this study demonstrated potential utility in HER2 2+ status discrimination. Background Human epidermal growth factor receptor 2 (HER2) is an orphan tyrosine kinase receptor. It is reported that HER2 is overexpressed in 15–20% of breast cancers. Overexpression of HER2 in breast cancer correlates with shortened disease-free survival. Compared with HER2-negative patients, patients with HER2-positive breast cancers have a poor prognosis, a high probability of lymph node metastasis and a high risk of recurrence (1–3). However, previous studies h...

In this study, we report the preliminary experience and clinical outcome of robotic assisted quadrantectomy (RAQ) and immediate partial breast reconstruction (IPBR) with RLDFH. Patient concern: Decreasing and avoid back scar length after latissimus dorsi flap harvest. Diagnoses: One 28 years old female with left breast cancer underwent RAQ and IPBR with RLDFH. Initially, she was diagnosed with left breast infiltrating carcinoma that was clinical stage T3N1M0 and triple negative. Interventions: Neoadjuvant chemotherapy consisting of 4 cycles of epirubicin and cyclophosphamide followed by 4 cycles of docetaxel was...

CONCLUSION Cognitive impairment can affect daily functioning, quality of life, and capacity to work in patients with cancer and those in remission. Consequently, cognitive assessment is now an important and necessary part of a comprehensive oncological care plan. Cancer-related cognitive impairment might be due to the direct effects of the cancer itself, nonspecific factors, or comorbid conditions that are independent of the disease and/or due to the adverse effects of the treatment or combination of treatments given for the disease. The prevalence and extent of cognitive impairment associated with cancer is recognized but...

In conclusion, this combined metabolic approach appears effective in treating advanced TNBC, given this patient’s complete response with a good quality of life.Now, there is one thing that is interesting here. The doses of chemotherapy used were considerably lower thanwhat is usually used, with doses decreased by at least half or more. Does this mean anything? Who knows? cPR rates for TNBC have been reported to range from 20-35%. It could mean the regimen made the chemotherapy more effective, or it could mean that this woman just happened to have a particularly chemosensitive tumor. Even if we take this case report a...

Abstract Purpose To evaluate the accuracy of residual microcalcifications on mammogram (MG) in predicting the extent of the residual tumor after neoadjuvant systemic treatment (NST) in patients with locally advanced breast cancer and to evaluate factors affecting the accuracy of MG microcalcifications using magnetic resonance imaging (MRI) as a reference. Methods The patients who underwent NST and showed suspicious microcalcifications on MG comprised our study population. Clinicopathologic and imaging (MG, MRI) findings were investigated. Agreemen...

Conclusion Among imaging modalities, breast MRI can potentially distinguish between ypT0 and ypTis after NCT, especially in patients with triple-negative breast cancer. This information can help clinicians evaluate tumor response to NCT and plan surgery for breast cancer patients of all subtypes except for those with HER2-enriched tumors after NCT.
