Abstract [eng] |
Breast cancer is the most common cause of mortality due to cancer for women both inLithuania and worldwide. Chances of survival after diagnosis differ significantly depending on thestage of disease at the time of diagnosis. Extended term periods are required to estimate survival of,e.g., 15–20 years. Moreover, since mortality of the average population changes with time, estimates ofsurvival of cancer patients derived after a long period of observation can become outdated and can beno longer used to estimate survival of patients who were diagnosed later. Therefore, it can be usefulto construct analytic functions that describe survival probabilities. Shorter periods of observation canbe enough for such construction. We used the data collected by theLithuanian Cancer Registryfor ouranalysis. We estimated the chances of survival for up to 5 years after patients were diagnosed withbreast cancer in Lithuania. Then we found analytic survival functions which best fit the observeddata. At the end of this paper, we provided some examples for applications and directions for furtherresearch. We used mainly the Kaplan–Meier method for our study. |
