To the Editor.— I disagree with the conclusions
of the article by Dr Grönberg and colleagues1
on the characteristics of prostate cancer in families potentially linked or
potentially unlinked to the hereditary prostate cancer 1 (HPC1) gene.
First, on comparing the tumor stage in families potentially linked and
those not shown to be linked, the authors state there is higher-stage disease
with HPC1 linkage. This statement is based on a comparison
with a reference population from the National Cancer Database but not with
the unlinked families. When the linked and unlinked families are compared,
there is no difference (P=.16, Fisher exact test).
