Abstract

Neoadjuvant therapy, an integral component of modern oncological care, involves the administration of systemic treatments prior to surgical intervention. This review provides a comprehensive examination of neoadjuvant approaches across various cancer types, encompassing breast, esophageal, pancreatic, and rectal cancers. By elucidating the clinical benefits, evolving strategies, and emerging trends, this analysis underscores the pivotal role of neoadjuvant therapy in optimizing surgical outcomes and advancing therapeutic paradigms.

The primary objective of neoadjuvant therapy is to downsize tumors, eradicate micro-metastatic disease, and enhance surgical resectability. In breast cancer, neoadjuvant chemotherapy has revolutionized the management of locally advanced and HER2-positive tumors, enabling breast-conserving surgery and improving overall survival. Similarly, in esophageal and rectal cancers, neoadjuvant chemoradiotherapy has demonstrated significant reductions in tumor size, facilitating potentially curative resections. In pancreatic cancer, neoadjuvant approaches have emerged as a promising strategy to address the challenges posed by locally advanced disease. Preoperative chemotherapy or chemoradiotherapy has shown potential in converting initially unresectable tumors to resectable status, providing a window of opportunity for curative surgery. Advancements in molecular profiling and personalized medicine have further refined neoadjuvant strategies. Biomarker-driven approaches, including hormone receptor status in breast cancer and microsatellite instability in colorectal cancer, guide treatment selection and optimize therapeutic efficacy. Moreover, neoadjuvant immunotherapy is an evolving frontier, with early clinical trials demonstrating promising results in various malignancies.

The integration of neoadjuvant therapy into standard treatment protocols necessitates a multidisciplinary approach, involving close collaboration between medical oncologists, radiation oncologists, surgeons, and pathologists. Accurate staging, treatment response assessment, and surgical planning are crucial elements in achieving optimal outcomes. In conclusion, neoadjuvant therapy represents a transformative approach in modern oncology, with demonstrated benefits across multiple cancer types. By enhancing surgical resectability, eradicating micro-metastatic disease, and facilitating organ preservation, neoadjuvant strategies have redefined therapeutic paradigms. Continued research and collaborative efforts are imperative to refine patient selection criteria, optimize treatment regimens, and explore novel agents, ultimately ensuring the continued advancement and integration of neoadjuvant therapy in clinical practice.
