Q. How radiation therapy differ in neoadjuvant and adjuvant cases?
Doctor Answer is medically reviewed by SecondMedic medical review team.
Neoadjuvant and adjuvant radiation therapy represent two unique approaches to cancer treatment.
Neoadjuvant radiation therapy is used before surgery to shrink a tumor, increasing the likelihood of successful surgical removal. It can also be used alone as a primary treatment modality when surgery isn't appropriate or practical. In addition, neoadjuvant radiation carries the potential to prevent metastasis; if some cancer cells are already present in places away from the main tumor site, neoadjuvant treatment can help stop them from spreading further.
Adjuvant radiation therapy differs in its approach; it's administered after surgery has been performed and is designed specifically to target any remaining cancerous tissue that may still reside near the location of the original tumor. This form of therapy provides an additional layer of protection against recurrence or metastasis by destroying any remaining malignant cells that may have gone undetected during surgical removal - thus providing an increased chance for improved long-term outcomes for patients with certain types of cancers.
