Lung cancer treatment and prognosis by stages
Result for non small cell lung cancer
There are 4 primary stages for lung cancer. In 2007 a worldwide research study (the Lung Cancer Staging Project) gathered information about lung cancer on more than 81,000 patients from 19 nations. The research gave the following statistics about survival for non small cell lung cancer. There is a variety of stats for each stage since for some patients the stage was based upon the results of scans and tests, and for other patients the stage was discovered during surgery.
Stage 1
This is the earliest stage therefore has the best outcome. Depending upon where the cancer is, it is often possible to eliminate stage 1 lung cancer with surgery. Sadly, it is not very common for lung cancer to be detected this early. Stage 1 non small cell lung cancer is divided into 2 phases, stage 1A and 1B.
Of all the people with stage 1A non small cell lung cancer, between 58 and 73 people out of every 100 (58 % to 73 %) will make it through for 5 years or more after medical diagnosis.
Of all the people with stage 1B non small cell lung cancer, in between 43 and 58 individuals from every 100 (43 % to 58 %) will endure for 5 years or more after they are detected.
Stage 2
Non small cell lung cancer stage 2 is likewise divided into stage 2A and 2B.
For stage 2A lung cancer, in between 36 and 46 from every 100 individuals identified (36 % to 46 %) will make it through for 5 years or more with treatment.
For stage 2B non small cell lung cancer, in between 25 and 36 out of every 100 individuals detected (25 % to 36 %) will survive for 5 years or more after they are diagnosed.
Stage 3
As you may expect, the survival stats fall with more advanced stages of lung cancer. Once again, stage 3 is divided into stage 3A and stage 3B.
For stage 3A non small cell lung cancer, between 19 and 24 from every 100 individuals identified (19 % to 24 %) will survive for 5 years or more after they are diagnosed.
For stage 3B, between 7 and 9 out of every 100 individuals identified (7 % to 9 %) will endure for 5 years or more after they are detected.
Stage 4
The most advanced stage of lung cancer is stage 4. It implies that the cancer has actually spread. Understandably, the survival data are extremely low for this stage. Unfortunately, lung cancer is often identified late and for many individuals the cancer has already spread out when they are identified. Just in between 2 and 13 from every 100 people detected with stage 4 non small cell lung cancer (2 % to 13 %) will endure for 5 years or more after medical diagnosis.
It can seem illogical for stage 3B cancer to have 5 year survival rates from 7 % to 9 % and stage 4 from 2 % to 13 %. This is due to the fact that the staging system just looks at the level of the cancer It does not look at the particular kinds of cancer. So the stage 4 group may consist of more people who have gradually growing cancers or cancer that responds very well to particular treatments than the stage 3 group.
Outcome for small cell lung cancer
Sometimes physicians divide small cell lung cancers into just 2 groups. These are restricted disease (the cancer has not spread out beyond the lung) and extensive disease (the cancer has actually spread out beyond the lung).
Of all the people identified with small cell lung cancer, around 30 from 100 (30 %) have actually limited disease at the time of medical diagnosis. With treatment about 25 from every 100 people (25 %) will endure for 2 years or more.
2 out of 3 people with small cell lung cancer currently have substantial disease at the time of diagnosis. Unfortunately the survival rate is really low. With treatment, less than 5 from every 100 individuals (5 %) will endure for 5 years or more after medical diagnosis.
The Lung Cancer Staging Project put the TNM staging system to give the following statistics about survival based upon the stage discovered by scans and tests. The job consisted of more than 8,000 patients with small cell lung cancer.
Stage 1
The earliest stage of small cell lung cancer is stage 1. Medical professionals divide this group into 2 further stages, stage 1A and 1B.
Of all individuals with stage 1A small cell lung cancer, nearly 40 from every 100 identified (40 %) will survive for 5 years or more after medical diagnosis.
Of all individuals with stage 1B small cell lung cancer, around 20 out of every 100 identified (20 %) will endure for 5 years or more after they are detected.
Stage 2
Small cell lung cancer that is stage 2 is also divided into stage 2a and 2B.
For stage 2A lung cancer, nearly 40 from every 100 people identified (40 %) will make it through for 5 years or more after they are detected.
For stage 2B small cell lung cancer, almost 20 out of every 100 individuals detected (20 %) will make it through for 5 years or more after diagnosis.
The survival rates for stage 2A appeared to be higher than for stage 1B. Researchers believe this is due to the fact that the research had few patients in the stage 2A group. They recommend that those stats might not be so dependable as the others.
Stage 3
As you might anticipate, the survival data fall with advanced stages of lung cancer. Once more, stage 3 is divided into stage 3A and stage 3B.
For stage 3A small cell lung cancer, nearly 15 out of every 100 people identified (15 %) will make it through for 5 years or more after they are detected.
For stage 3B, around 10 out of every 100 individuals detected (10 %) will make it through for 5 years or more after diagnosis.
Stage 4
The most innovative stage of small cell lung cancer is stage 4. It suggests the cancer has infected other parts of the body. Understandably, the survival data are most affordable for this stage. Regrettably, lung cancer is frequently diagnosed late and for lots of people the cancer has actually currently spread out when they are diagnosed.
Only about 1 from every 100 people (1 %) identified with stage 4 small cell lung cancer will make it through for 5 years or more.
