Understanding MET Mutations in Lung Cancer
The MET gene is found on chromosome 7 and is important for cell processes like growth. When the MET gene changes, it can have big effects, especially on different lung cancers. Knowing about these changes helps create better treatments.
What is the MET Gene?
The MET gene makes a special protein that helps cells communicate. If it mutates, it can cause too much cell growth. This is common in lung adenocarcinoma. A study showed that about 25% of non-small cell lung cancers had higher MET levels than normal tissue.
Types of MET Biomarkers Relevant to Lung Cancer
For lung cancer, finding MET alterations is key. There are two main MET biomarkers for treatment:
- MET Gene Amplification: High MET gene levels have been seen in some kinds of lung adenocarcinoma samples. They’re higher than in other genes like EGFR and HGF.
- MET Exon 14 Skipping: This change affects the MET pathway in non-small cell lung cancer. Around half the cases have this mutation. Finding these mutations has been tough with some tests.
Identifying MET biomarkers is crucial. It lets doctors use specific drugs that improve survival and shape better treatments.
Who is Most Likely to Have MET Alterations?
Knowing who gets prevalence of MET alterations is key. It helps us find the right treatment for different lung cancers. MET changes are mostly seen in specific types of lung cancer. This shows why genetic tests are crucial for creating personalized treatment plans.
Prevalence of MET Alterations in Different Lung Cancer Types
About 3-4% of lung adenocarcinomas have MET mutations. These are common in non-small cell lung cancer. Also, 32% of pulmonary sarcomatoid carcinomas show MET exon 14 skipping mutations. In patients who haven’t received any treatment, we find MET mutations in about 2.6% of non-small cell lung cancer cases.
Finding these changes is very important. They can be key targets in treating met mutation lung cancer.
Demographic Factors Affecting MET Mutations
Certain factors affect the chance of having MET mutations in lung cancer patients. The average age of patients with MET exon 14 changes is about 73. Women and those who’ve never smoked tend to have these alterations more. On the other hand, younger patients, under 65 and with a history of smoking, often have MET amplifications.
Knowing these details helps tailor treatments to each patient’s needs. It’s vital for handling different kinds of lung cancer.

Detecting MET Mutations in Lung Cancer
Finding MET mutations is key for tailoring lung cancer treatments. We have advanced methods like next-generation sequencing (NGS) and liquid biopsies. These techniques are crucial for accurate diagnosis and suitable treatment plans.
Next-Generation Sequencing (NGS)
NGS testing is a powerful tool for spotting MET mutations in lung cancer. It allows for the analysis of many genetic changes at once. This is done through tumor tissue samples.
Studies involving over 54,000 non-small cell lung cancer (NSCLC) patients utilized targeted NGS. It helped identify specific MET mutations in 138 patients. These findings support creating personalized treatments.
Biopsy vs. Liquid Biopsy
Traditional biopsies and liquid biopsies are both used to detect MET mutations. Biopsies take tissue samples from tumors but can be hard to do. Liquid biopsy, on the other hand, uses blood samples. It’s less invasive and more comfortable for patients.
This method is notable for its efficiency in identifying biomarkers. By using both biopsy types, doctors can more accurately find MET mutations. This leads to better treatment choices.
Combining NGS with liquid biopsy gives doctors a better way to find MET mutations. This approach improves prospects of selecting effective treatments for patients. For more info on the importance of MET mutation detection, click here.

This drug is especially good for lung cancer with MET exon 14 skipping mutations, found in 3-4% of cases. About 32% responded to crizotinib, with a median of 7.3 months till the cancer progressed again.
Chemotherapy and Immunotherapy Options
Chemotherapy and immunotherapy are also key. For MET amplification, crizotinib’s results differed based on the amplification level. High MET amplification saw up to 6.7 months before cancer progressed. Side effects like swelling and stomach issues were common. Using chemo and immunotherapy together can help, especially if MET inhibitors aren’t enough on their own.
| Treatment Option | Response Rate | Median PFS | Adverse Events |
|---|---|---|---|
| Capmatinib | Varies based on mutation | Pending more studies | Monitor for side effects |
| Crizotinib (for MET exon 14) | 32% | 7.3 months | Peripheral edema, fatigue |
