Inclusion Criteria

1.Female patients aged 18 years or older with early high-risk(T1cN1;T2N1;T3N0)and locally advanced and inflammatory breast cancers (stage III A-C according to AJCC) suitable for neoadjuvant treatment;2.Histologically confirmed unilateral invasive breast cancer;3.HER2 positive disease according to ASCO/CAP current guidelines;4.Known estrogen (ER) and progesterone receptor (PgR) status;5.Availability of a representative paraffin-embedded(FFPE)tumor block taken at diagnostic biopsy for central confirmation of HER2 status, assessment of ER, PgR, Ki67 and PD-L1 expression and for biomarker evaluation is mandatory. Note:the diagnostic biopsy of the breast lesion may have been taken before the screening procedures start. If diagnostic sentinel node biopsy if performed, an FFPE block should be made available, along with the tumor block of the primary tumor. An FFPE tumor block is also mandatory after the first cycle of therapy. Surgery tissue (residual tumor or tumor bed in case of pCR and axillary node material) is also mandatory;6.Consent to the collection of blood samples mandatorily before starting neoadjuvant treatment, after the first cycle of therapy, at the end of neoadjuvant treatment (before surgery), 6 months after surgery and at the end of all treatments;7.ECOG performance status 0 or 1;8.For women who are not postmenopausal (= 12 months of non-therapy-induced amenorrhea) or surgically sterile (absence of ovaries and/or uterus): agreement to remain abstinent or use single or combined contraceptive methods that result in a failure rate of < 1% per year during the treatment period and for at least 6 months after the last dose of study drugs. Abstinence is only acceptable if it is in line with the preferred and usual lifestyle of the patient. Periodic abstinence (e.g., calendar,ovulation,symptothermal,or postovulation methods) and withdrawal are not acceptable methods of contraception.Examples of contraceptive methods with a failure rate of <1% per year include tubal ligation, male sterilization, hormonal implants, established, proper use of combined oral or injected hormonal contraceptives, and certain intrauterine devices;9.Written informed consent to participate in the trial (approved by the Institutional Review Board [IRB]/ Independent Ethics Committee [IEC]) obtained prior to any study specific screening procedures;10.Willing and able to comply with the protocol

HBsAg and positive hepatitis B core antigen) are eligible.Pts positive for hepatitis C (HCV) antibody are eligible if polymerase chain reaction assay (PCR) is NEG for HCV RNA;17.Active TBC;18.Severe infections within 4 weeks pre-D1, including hospitaliz. for infections complications, bacteremia or severe pneumonia.
