Potential Benefits of Neoadjuvant Chemotherapy in Clinically Node-Positive Luminal Subtype- Breast Cancer.
Conclusion: Despite the low pCR rate, the tumor response and BCS conversion rates after NAC of luminal HER2- breast cancer were similar to those of other subtypes. NAC has the potential benefit of reducing the size of breast cancer, thereby increasing the BCS conversion rate in luminal HER2- breast cancer. PMID: 31598341 [PubMed]
AbstractBackgroundThe NEOSPHERE trial suggested that pertuzumab (P) added to a combination of docetaxel and trastuzumab (T) as a neoadjuvant therapy in HER2 positive breast cancer (HER2+ BC) patients (pts) significantly enhances pathological complete response (pCR) rates. Here, we report our institution experience, focusing on stage III tumors.MethodsWe reviewed clinical and pathological response (residual cancer burden, RCB) in 355 HER2+ BC treated between 2010 and 2017 with neoadjuvant chemotherapy combined with T (n = 291) or TP (n = 64). Results were adjusted according to clinical stage, ho...
Conclusions: The use of CT information during boost field planning could reduce the risk of LR among patients undergoing BCT. Neoadjuvant and adjuvant treatments for breast cancer did not show the significant difference in respect to the outcome of LR.
In conclusion, our findings support CTP as the optimum neoadjuvant regimen for HER2-positive breast cancer, with the best pCR and acceptable toxicity compared with CT. MP provides a therapeutic option for patients with poor performance status. PMID: 31015833 [PubMed]
ConclusionThis less toxic, anthracycline-free regimen appears to be a significantly effective neoadjuvant therapy for patients with pure HER2 breast cancer at low relapse risk.
CONCLUSIONSFor patients with Luminal/HER2 negative breast cancer, the combination of the imaging features of the tumor and the mammary gland, obtained with 18F-FDG PET-CT at baseline and after the first cycle of NAC, may allow the physician to evaluate the probability of BCS.
CONCLUSION: BCS after NACT is feasible and safe in terms of LRR, DFS and OS, if patients are properly studied and selected. Indication to BCS after NACT needs of a multidisciplinary assessment considering clinical staging, biological characteristics, the radiological response pattern and the expected concordance between imaging and histology.

We report the case of a 68-year-old Caucasian female with a family history of cancer. Core biopsy revealed that she had grade II oestrogen receptor-negative, Her2-positive invasive ductal carcinoma. She was offered neoadjuvant chemotherapy with Herceptin and subsequently underwent breast-conserving surgery. Microscopic examination of the post-treatment breast surgical specimen showed a partial pathological response with large areas of tumour regression. The sentinel lymph node showed frequent large single and multinucleate giant cells with hyperchromatic nuclei located predominantly within the subcapsular and medullary sin...
In conclusion, sufficient evidence is now available to suggest that breast conservation after neoadjuvant chemotherapy is safe and effective for selected patients. Though neoadjuvant chemotherapy may increase the complexity of breast conservative treatment, a close collaboration between a multidisciplinary team and use of oncoplastic surgical techiques permit to optimize oncological and cosmetis outcomes.

In conclusion, the concurrent use of trastuzumab and anthracycline-based NAC for certain HER2-positive locally advanced breast cancers significantly improves the pCR rates without obvious increases in the cardiotoxicity. PMID: 30310287 [PubMed]
