Researchers have discovered a way to personalize the treatment of stage N3 nasopharyngeal carcinoma (NPC) by using a patient’s pre-treatment Epstein-Barr virus (EBV) DNA levels. The study found that for high-risk patients with high EBV DNA levels, increasing the number of induction chemotherapy (IC) cycles from 3 to 4 significantly improved their survival outcomes. However, for low-risk patients with low EBV DNA levels, the 3-cycle IC regimen was just as effective as the 4-cycle regimen. This research could help guide doctors in selecting the optimal number of IC cycles for individual patients, ultimately leading to better treatment outcomes for those diagnosed with this advanced stage of NPC. Nasopharyngeal carcinoma is a type of head and neck cancer that is particularly prevalent in certain parts of Asia.
Personalized Approach to Induction Chemotherapy for Stage N3 NPC
Nasopharyngeal carcinoma (NPC) is a type of cancer that originates in the nasopharynx, the upper part of the throat behind the nose. It is a common cancer in Southeast Asia, especially in southern China and Eastern Asia. One of the key challenges in treating NPC is that it is often diagnosed at a later, more advanced stage, with around 70% of patients presenting with locoregionally advanced nasopharyngeal carcinoma (LA-NPC).
The standard treatment for LA-NPC is concurrent chemoradiotherapy (CCRT), which combines chemotherapy and radiation therapy. However, even with this approach, about 30% of patients still experience local recurrence or distant metastasis, which can be a major cause of treatment failure.
In recent years, the use of induction chemotherapy (IC) before CCRT has been shown to further improve the survival of LA-NPC patients. IC helps to reduce the tumor burden and eliminate potential micrometastases, which can help control distant metastasis and improve long-term survival.
Predicting Prognosis with Pre-treatment EBV DNA Levels
One of the key factors that can affect the prognosis of NPC patients is the presence of advancednasopharyngealcarcinoma’>locoregionally advanced NPC.
