What is more for cancer patients: increased screening or treatment innovation?

Let’s get this out of the way: both are clearly important.  Within appropriate screening, patients don’t get the treatment they need.  Further, delayed screening can make treatments less effective if the cancer has progressed or metastasized.  On the other hand, without effective treatment, screening won’t have a major impact on patient outcomes. The question is,…

Cancer survival around the world

An interesting study measuring trends in cancer survival between 2000 and 2014 found, unsurprisingly, that patients in more developed countries had better survival. For women diagnosed with breast cancer between 2010 and 2014, 5-year survival rates reached 89.5% in Australia and 90.2% in the United States, but generally varied worldwide and remained low in some…

Kaplan-Meier Survival Curves

Survival analysis is used in many contexts.  Some examples include: Medical research: fraction of patients living for a certain amount of time after treatment. Economics: length of time people remain unemployed after a job loss. Engineering: time until failure of machine parts. Ecology: how long fleshy fruits remain on plants before they are removed by…

Hospice Care and Lung Cancer Survival

Metastatic non–small-cell lung cancer, the leading cause of death from cancer worldwide, is a debilitating disease that results in a high burden of symptoms and poor quality of life; the estimated prognosis after the diagnosis has been established is less than 1 year. Due to the high mortality rates of metastatic non-small-cell lung cancer, palliative…
