Barr body frequency in esophageal cancer in Indian women.
In a retrospective study, Barr body frequency was analyzed in 50 consecutive cases of esophageal cancer in females. The majority (95%) of the tumors had less than 20% Barr body frequency (of which 80% showed less than 10%), while normal controls showed 30% to 45% Barr body frequency. The mechanism(s) involved in lowering the frequency is not known at present.
