Letter to the Editor: Survival of women with locally advanced breast cancer at a teaching hospital in Lahore

Madam, the aim of this letter is to improve the understanding of a relatively new statistical technique (in context of research in our country) to acquire high quality research and health care services. We recently read the above mentioned article in the latest issue of this journal. Unfortunately, little is known and published about the survival of cancer patients in our country mainly because we do not have any functional central recording system (Cancer Registry) where all the cancer patients could be registered. In such a scenario, authors of the above article should be appreciated that they registered their patients and followed them up for a fairly long period to estimate the survival.
