Evaluation of the predictive role of tumor immune infiltrate in HER2-positive breast cancer patients treated with neoadjuvant anti-HER2 therapy without chemotherapy.

CONCLUSIONS: LPBC was marginally associated with higher pCR rate than non-LPBC in LT treated HER2+ BC patients. Quantitative assessment of the immune infiltrate by m-IF is feasible and may help correlate individual immune cell subpopulations and immune cell profiles with treatment response.

AbstractBackgroundHER2 blockade in combination with chemotherapy (CT) remains the treatment of choice for patients with early HER2+ BC, irrespective of ER status. Patients with HER2+ early BC co-expressing ER may benefit from HER2 blockade in combination with endocrine therapy (ET) and new targeted agents. Elderly patients benefit from HER2 blockade as much as younger ones but they have higher risks of adverse events, mostly induced by the CT partner, making de-escalation of CT appealing. Recent data have elucidated cyclin-dependent kinases 4 and 6 (CDK4/6) as key therapeutic targets functioning downstream of both ER and H...

CONCLUSIONS: This study confirmed the therapeutic impact of lapatinib, trastuzumab, and paclitaxel therapy for each ER- and ER+ subgroup of HER2+ patients. Development of further strategies and tools is required, particularly for luminal HER2 disease. PMID: 29445928 [PubMed - as supplied by publisher]
