Breast cancer and pregnancy.
BACKGROUND
Breast cancer developing during pregnancy or lactation is such an infrequent problem that, when it occurs, physicians are confronted with ethical and therapeutic challenges. Moreover, there are very few references to compare or discuss breast cancer in pregnant women in Taiwan. We hope that data from this review will add to our understanding of such difficult problem as well as help improve the treatment of our patients.


METHODS
Between 1979 and 1988 the charts of 21 women, who were pregnant or postpartum within one year of the breast cancer diagnosis, were analyzed retrospectively. All of the patients were followed until Dec. 1990. Patients with pregnancy-associated breast cancer were compared with nonpregnant women (199 cases) of similar age who were treated at the same hospital and during the same period.


RESULTS
We found no statistical differences in the overall 5-year survival rate between pregnant (57.1%) and nonpregnant (69.6%) groups. It is noteworthy that the time lag was significantly longer in the pregnant group than in the nonpregnant group. A stage-by-stage comparison showed equivalent survival rates between pregnant and nonpregnant patients. The pregnant patients at stage II had a somewhat lower survival rate; however, there was no statistical significance.


CONCLUSIONS
The rule of cancer treatment, "early diagnosis followed by aggressive management," is still a key principle to improve the treatment in pregnant women with breast cancer.
