Treatment for Her2-positive breast cancer is increasingly being tailored across the disease continuum, with sophisticated use of therapies both before (neoadjuvant) and after (adjuvant) surgery. The primary goal of neoadjuvant therapy is to shrink the tumor, making surgery easier and allowing oncologists to assess how well the cancer responds to the drugs. A pathological complete response (pCR) in the neoadjuvant setting—meaning no invasive cancer is found at surgery—is strongly linked to an excellent long-term prognosis.

Patients who do not achieve a pCR are known to be at a higher risk of recurrence, necessitating escalation of treatment in the adjuvant setting. This strategy of identifying and intensifying post-surgical therapy based on residual disease status has become a hallmark of modern precision oncology. For these high-risk individuals, ADCs like T-DM1 or the newer T-DXd are frequently employed to eradicate microscopic residual disease, a strategy proven to dramatically improve disease-free survival rates compared to earlier, less intense regimens.

This commitment to risk-adapted, sequenced therapy underscores the importance of continued research into optimizing the sequence and duration of treatment. The success in preventing recurrence and improving survival rates through tailored neoadjuvant and adjuvant protocols confirms the critical role of precision sequencing as a key driver of pharmaceutical use across the entire Her2 Positive Breast Cancer Treatment Market therapeutics space.

FAQ 1: What is the purpose of neoadjuvant therapy in Her2-positive breast cancer? Neoadjuvant therapy (treatment before surgery) is used to shrink the tumor, make surgery easier, and allow doctors to assess the tumor's response to the targeted drugs.

FAQ 2: What determines if a patient needs "escalation" of adjuvant therapy? Patients who do not achieve a pathological complete response (pCR) after neoadjuvant therapy have a higher risk of recurrence and typically receive escalated adjuvant therapy (like certain ADCs) to try to eliminate any remaining cancer cells.
