Lung Cancer Survival Rate

A variety of factors influence lung cancer survival rates. The sort of cancer, the stage it is at when diagnosed, and the overall condition of the patient all play a role in determining survival. Cancer survival is typically expressed in terms of a 5-year survival rate, which is the percentage of patients with cancer who survive at least 5 years right after their cancer is diagnosed.

Studies have shown that five-year survival rates among non-little cell lung cancer patients vary by stage. Stage patients have the ideal survival, of close to 50 percent at 5 years. Approximately one-quarter of stage II patients survive to 5 years, as compared to eight percent of stage III patients and only two percent of stage IV patients. In common, smaller cell lung cancer tends to proceed even more rapidly to terminal illness. Ten to fifteen percent of patients with restricted-stage smaller cell lung cancer, and among 1 and two percent of those with extensive-stage cancer, survive to five years.

Estimates of cancer survival do not reflect present treatment advances that may lead to much better probabilities of survival, mainly because they are usually calculated for a five-year period that does not contain the previous year. Further, every patient responds to treatment in a exclusive way aggregate estimates do not account for individual factors that may perhaps increase or worsen the likelihood of survival.

The overall number of deaths in the United States from lung cancer rose throughout the 1980s, and began to drop for men in the 1990s. Yet, a related decrease has not been observed amongst women. Over fifty thousand current and former smokers have been enrolled in the National Lung Screening Trial to locate out if chest x-rays and CT scans taken prior to the onset of lung cancer symptoms might strengthen early diagnosis and hence survival.
