Five-year survival rates can be used to compare the effectiveness of treatments. Use of five-year survival statistics is more useful in aggressive diseases that have a shorter life expectancy following diagnosis, such as lung cancer, and less useful in cases with a long life expectancy, such as prostate cancer.
Cystic fibrosis (also known as CF or mucoviscidosis) is an autosomal recessive genetic disorder affecting most critically the lungs, and also the pancreas, liver, and intestine.
The National Institute of Health (NIH) attributes the increase in the 5-year relative survival of prostate cancer (from 69% in the 1970s to 100% in 2006) to screening and diagnosis and due to the fact that men that participate in screening tend to be healthier and live longer than the average man and testing techniques that are able to detect ...

After two years, about 80% of the Gene A patients survive, but less than half of patients with Gene B. To generate a Kaplan–Meier estimator, at least two pieces of data are required for each patient (or each subject): the status at last observation (event occurrence or right-censored), and the time to event (or time to censoring).
The objective of cancer screening is to detect cancer before symptoms appear, involving various methods such as blood tests, urine tests, DNA tests, and medical imaging. [ 1 ] [ 2 ] The purpose of screening is early cancer detection, to make the cancer easier to treat and extending life expectancy. [ 3 ]
Cytoreductive surgery (CRS) is a surgical procedure that aims to reduce the amount of cancer cells in the abdominal cavity for patients with tumors that have spread intraabdominally (peritoneal carcinomatosis). It is often used to treat ovarian cancer but can also be used for other abdominal malignancies.
The name's etymological origin is the Greek word ὄγκος (ónkos), meaning "tumor", "volume" or "mass".
