The use of larotrectinib/vitaca can generally extend a patient's life by several years

Larotrectinib(Larotrectinib) is a targeted therapy specifically designed to treat cancer patients with NTRK gene fusions. NTRK gene fusion is a common driver mutation in various tumors. Larotrectinib significantly improves the prognosis of patients by inhibiting the TRK receptor and blocking the growth and spread of tumor cells.

1. Mechanism of action and efficacy

Larotrectinib can target the tumor growth caused by the TRK fusion gene and provides a new treatment option for solid tumors with NTRK gene fusion, such as non-small cell lung cancer (NSCLC), soft tissue sarcoma, thyroid cancer, etc. Clinical studies have shown that larotrectinib can effectively reduce tumor volume, slow down disease progression, and prolong patient survival, especially for patients with NTRK fusion-positive advanced tumors. The efficacy of larotrectinib has shown good response rates in a variety of cancer types, and some patients have achieved long-term progression-free survival.

2. Possibility of extending survival period

The specific time to extend a patient's life will vary depending on the patient's condition, treatment response, and tumor type. For patients diagnosed early and without severe drug resistance, the use of larotrectinib can significantly improve survival. Typically, patients taking larotrectinib see significant improvements in survival, especially in patients who get treatment early and respond well to the drug.

3. Clinical observation and survival data

According to existing clinical trial data and patient reports, larotrectinib has a significant effect on prolonging the survival of NTRK fusion-positive patients. In some studies, patients had stable disease or continued remission for months or even years after receiving larotrectinib. However, each patient's response to treatment is different, and the persistence of treatment effects and prolonged survival will be affected by many factors.
