What is an abnormal EGFR?

A eGFR below 60 for three months or more or a eGFR above 60 with kidney damage (marked by high levels of albumin in your urine) indicates chronic kidney disease.

How common are EGFR mutations in NSCLC?

EGFR mutations in NSCLC cells were first discovered in 2004 [2, 3]. The majority of EGFR mutations in NSCLC occurs in exons 18– 21 of the tyrosine kinase domain of the receptor. EGFR mutations occur in 40%–60% of South-East Asian patients or 10%–20% of Caucasian patients with lung adenocarcinomas [4–6].

What percentage of NSCLC is EGFR positive?

In total, 30,466 patients with an EGFR mutation were reported among 115,815 patients with NSCLC. The overall pooled prevalence of all EGFR mutations and EGFR exon 19 or 21 mutations was 32.3% (95% CI: 30.9% to 33.7%) and 32.2% (95% CI: 29.6% to 34.8%), respectively (Table ​ 1).

Does EGFR cause cancer?

EGFR (epidermal growth factor receptor) is a protein on cells that helps them grow. A mutation in the gene for EGFR can make it grow too much, which can cause cancer.

Should I worry if my GFR is 56?

A GFR of 60 or higher is in the normal range. A GFR below 60 may mean kidney disease. A GFR of 15 or lower may mean kidney failure.

Will drinking water increase my GFR?

found increased water intake actually decreases GFR. It might therefore seem that any “toxin” removed purely by glomerular filtration is cleared less efficiently in the setting of increased water intake; however, it is not certain such changes in GFR persist over time.

What are common EGFR mutations?

The two most common EGFR mutations are short in-frame deletions of exon 19 and a point mutation (CTG to CGG) in exon 21 at nucleotide 2573, which results in substitution of leucine by arginine at codon 858 (L858R).

What causes EGFR mutation?

The most common EGFR mutations include missing genetic material on exon 19 (19-del) or damage to exon 21 (21-L858R). These two mutations account for about 85% of the EGFR mutations of lung cancer cells. 6 Exon 20 insertion mutations may also occur, but they are much rarer.

Is EGFR genetic?

A gene that makes a protein that is involved in cell growth and cell survival. Mutated (changed) forms of the EGFR gene and protein have been found in some types of cancer, including non-small cell lung cancer.

What cancers have EGFR mutations?

EGFR Mutation is present in 5.48% of AACR GENIE cases, with lung adenocarcinoma, conventional glioblastoma multiforme, glioblastoma, colon adenocarcinoma, and non-small cell lung carcinoma having the greatest prevalence [4].

How long can you live with EGFR lung cancer?

In patients with EGFR del19 tumors specifically, the median overall survival was 45.7 months. “As many patients with this type of lung cancer eventually acquire resistance to EGFR TKIs, it’s important to consider the order of these therapies to provide patients with as many future treatment options as possible.

Should I worry if my GFR is 47?

What does it mean when your EGFR is above 60?

A eGFR below 60 for three months or more or a eGFR above 60 with kidney damage (marked by high levels of albumin in your urine) indicates chronic kidney disease. Your doctor will want to investigate the cause of your kidney disease and continue to check your kidney function to help plan your treatment.

What does it mean when Doctor says estimated GFR?

When the doctor or nurse says “estimated glomerular filtration rate” (eGFR) it’s a number that means how well your kidneys are filtering out wastes. Each kidney has one million basic small filters called “nephrons.” Each nephron keeps important substances in the body while filtering out waste into urine. When the doctor or nurse says “estimated

What does a low GFR mean for kidney disease?

Your GFR tells your doctor your stage of kidney disease and helps the doctor plan your treatment. If your GFR number is low, your kidneys are not working as well as they should. The earlier kidney disease is detected, the better the chance of slowing or stopping its progression. What are the Stages of Chronic Kidney Disease (CKD)?

What is the GFR rate for stage D kidney damage?
