Aggressive local treatment for screen-detected DCIS results in very low rates of recurrence.
OBJECTIVE
To review our institution's practice of treatment of a mammographically detected population of ductal carcinoma in situ (DCIS) patients and to determine the outcome.


METHODS
Between April 1989 and March 1994, 304 women with median age 59 years (range 51-65) with DCIS detected on screening mammogram, were treated in the Newcastle General and Royal Victoria Infirmary Hospitals, Newcastle-upon-Tyne, UK. More than half of the women (n=176, 57.8%) decided to have mastectomy. Other treatment options were wide local excision (WLE) with radiotherapy (n=97, 32%) and WLE alone (n=31, 10.2%). All except five received adjuvant hormone treatment.


RESULTS
Predominant DCIS was comedo in 122 (42%), followed by cribriform in 87 (30%) and micropapillary in 44 (15%) cases. Grade I was found to be commonest grade (54%) followed by grade II (27%) and grade III (11%). With a median follow-up of 88 months, there were six (2%) recurrences, all of which were in women who were given breast conservation treatment, WLE with radiotherapy (n=1, 1%) and without radiotherapy (n=5, 16.6%). Mastectomy in this series was not associated with any recurrence at all. In three cases the recurrence was invasive, one of who also had distant metastasis.


CONCLUSIONS
The findings of this study suggest that in women with DCIS suitable for breast conservation, WLE when combined with radiotherapy is associated with a very low recurrence rate.
