Trends in pre-operative needle biopsy use in invasive breast cancer diagnosis: a Dutch nationwide population study.

CONCLUSION: Results suggest that nationwide, clinics prioritise reliability and availability of ER and HER2 status, replacing FNAC by CNB. However, for optimal treatment planning for all patients, availability of pre-operative receptor status warrants further improvement. PMID: 33030998 [PubMed - as supplied by publisher]

CONCLUSION: The probability of nodal positivity after neoadjuvant chemotherapy was less than 3 per cent in patients with TNBC or HER2-positive disease who achieved a breast rCR on MRI. These patients could be included in trials investigating the omission of sentinel node biopsy after neoadjuvant chemotherapy.PMID:34157085 | DOI:10.1002/bjs.12026

Oncology (Williston Park). 2021 Mar 15;35(3):139-143. doi: 10.46883/ONC.2021.3503.0139.ABSTRACTThe Case A previously healthy woman, aged 32 years, presented to the oncology clinic with a 6-month history of left-breast tumor, mastalgia, and swollen axillary nodes. Physical examination was relevant for a 6-cm palpable mass in the upper outer quadrant of the left breast and an ipsilateral 2-cm, nonfixed axillary lymph node. Mammography showed a 1-cm mass in the upper outer quadrant, a 5.2-cm mass in the lower outer quadrant, and enlarged pathologic lymph nodes (BI-RADS category 5 disease). Breast ultrasound revealed 3 axillar...

In this study, our aim was to evaluate axillary nodal metastasis burden in patients with early-stage breast cancer who presented with metastatic lymph nodes diagnosed by fine needle aspiration biopsy (FNAB). METHODS: The data from 346 patients with cT1-T2 breast cancer who showed positive FNAB results and were seen at Tianjin Medical University Cancer Hospital from January 2014 to December 2017 were retrospectively analyzed. The patients were divided into high axillary nodal burden (≥ 3 positive lymph nodes) or low axillary nodal burden (one to two positive lymph nodes) groups. The clinical, radiological, an...

Conclusion: FNAC can be helpful in making diagnosis of TNBC and along with ER, PR, HER2 characterization, helpful in planning treatment strategy, saving time, manpower, and resources in the patient management.

CONCLUSIONS: This model could be a helpful tool for the surgeon to help in predicting which cases have a higher likelihood of achieving a pathologically complete response and therefore selecting those who may benefit from a post-neoadjuvant chemotherapy sentinel lymph node biopsy and avoid unnecessary axillary lymphadenectomy.

Conclusion: ICC using LBC can be a useful tool in assessing biomarkers in advanced cases of breast cancer where surgery is not possible or cases where ASCO/CAP guidelines for management are not followed.

CONCLUSIONS: This study shows considerable differences in the prognostic value of Ki67 but not ER in breast cancer depending on the diagnostic method. Furthermore, our findings show that both methods are insufficient in predicting true molecular subtypes. PMID: 29588372 [PubMed - indexed for MEDLINE]
