Summary: | An analysis of a series of
926 female patients, of whom
755 were followed for
3 years and
647 for
5 years after mastectomy, revealed age at menarche to be a valuable prognosticator. Survival rates were the lowest for women who had very early menarche (≦
11 years of age) but prognosis improved progressively with increase in menarchial age. Optimal menarchial age was found to be at age
15; onset of menses beyond this age was once again associated with an unfavorable outcome. The possible relationship between age at menarche and axillary node involvement was then examined from two points of view in an effort to establish whether early menarche would be associated with extensive nodal involvement, or whether it would retain its unfavorable prognostic significance independently of the extent of this involvement. Both of these hypotheses were found to be plausible in our series. It is stressed that further research on larger study populations is required before definitive conclusions can be drawn. |
