Researchers analyzed each therapy by length of survival, time to disease progression, and toxic effects.
The difference in length of survival was due to the pH, a measure of acidity, of the stool.
Thus the length of survival does not necessarily reflect better medical care but rather a better system for screening disease.
Average length of survival after diagnosis is 9 to 12 months.
But in 25percentt, who had a different pattern of disease, the operation improved both quality of life and length of survival.
That study, called NETT, for National Emphysema Treatment Trial, found that in about 25percentt of participants, the operation improved both quality of life and length of survival.
Since we calculate the length of survival from the time of diagnosis, ever more sensitive screening starts the clock ticking sooner.

Medical experts said that such cancers may be treated with radiation and chemotherapy but almost always grow back, and that the median length of survival with a glioblastoma is about 16 months.
I haven't heard of one similar with anything like the same length of survival". However, he added: "How they can say that he'll be completely unharmed I'm not sure.
In studies of humans as well as rats, Dr. Rutkove showed that these variations were closely correlated with disease progression and length of survival.
