Is platinib effective for lung cancer patients? How long can they live?

Platinib is mainly used to treat RET non-small cell lung cancer with positive gene fusion. It is a targeted inhibitor of receptor tyrosine kinase RET that can selectively inhibit the activity of RET kinase, thereby effectively inhibiting the proliferation of tumor cells expressing the RET gene. This property makes platinib an effective treatment for certain patients with lung cancer.

In practical applications, Platinib has demonstrated its efficacy. According to clinical research data, for patients with RET fusion-positive non-small cell lung cancer who have previously received platinum-containing chemotherapy, the objective response rate (ORR) of platinib treatment has reached 63.1%. Among them, 6.2% of patients achieved complete remission, and 56.9% achieved partial remission. This data fully illustrates the effectiveness of platinib in treating patients with this type of lung cancer.

A number of clinical studies have also given positive results regarding the survival of patients with lung cancer after taking platinib. It is particularly worth mentioning that the data from the ARROW study showed that the median duration of response in patients with RET fusion-positive non-small cell lung cancer after platinum treatment ( DOR) is up to 38.8 months, and overall survival (OS) is up to 44.3 months. This means that for patients who are suitable for platinib, their survival is expected to be significantly prolonged.

The effectiveness and survival of Platinib may also vary from person to person. In addition, as a drug, the use of platinib also needs to be under the guidance of a doctor to ensure safety and effectiveness.

Although platinib has shown significant efficacy in the treatment of non-small cell lung cancer, patients also need to pay attention to possible adverse reactions when using it. Common adverse reactions include constipation, fatigue, hypertension, osteomyalgia, edema, diarrhea, etc. In addition, abnormal blood tests are also a matter of concern. Therefore, when using platinib, patients should undergo relevant examinations regularly and adjust the drug dosage or take other necessary measures under the guidance of a doctor.
