st: comparing percentages for independent groups with different data sets

Dear Statalisters,
I am working on a paper about diagnostic accuracy of trans-rectal
ultrasound guided prostate biopsy schemes on prostate cancer. A
similar paper was published about this topic. These are 2 independent
groups with different data sets (I don't have their complete data set
of ).I need to compare these results with each other however I
couldn't figure out which test is suitable for this aim.
7/13 (53%) is my cancer detection rate for a 30 ml prostate site at
age <=50 (12 cores sampling results)
2/4 (50%) is their cancer detection rate for same size same age (8
cores sampling results)
I have 40 different result for a total of 1574 patients
Thanks in advance.
Alp
