Study information
Scientific title

Study hypothesis
1. In patients with mammographically detected DCIS to compare the effectiveness of complete local excision (CLE) alone with CLE followed by radiotherapy to the residual ipsi-lateral breast tissue and/or tamoxifen 20 mg daily for five years, in reducing the incidence of subsequent invasive carcinoma of the breast
2. To monitor contralateral disease within randomised arms of the trial

Condition
Breast Cancer
Intervention
1. Treatment A: Complete local excision with no further initial local or systemic therapy.
2. Treatment B: Complete local excision followed by supervoltage radiotherapy to the residual breast tissue to a dose of 50 Gy given in twenty-five fractions over five weeks. Radiotherapy to commence no later than eight weeks after the final surgical procedure.
3. Treatment C: Complete local excision followed by tamoxifen 20 mg daily for five years. Tamoxifen therapy to commence no later than eight weeks after the final surgical procedure.
4. Treatment D: Complete local excision followed by radiotherapy and tamoxifen (as above). If wished patients may be randomised for one treatment only, i.e. tamoxifen or radiotherapy, in which case the other treatment may electively be given or not given.

Eligibility
Participant inclusion criteria
1. Unilateral or bilateral DCIS which is cosmetically suited to breast conservation, which has been detected as a result of attendance at a screening centre, which is without evidence of invasion, and which has been completely excised as determined by free margins on histological examination
2. Patients with similarly defined DCIS lesions, in whom the diagnosis of DCIS has been made as a result of mammograms taken following referral to a diagnostic clinic
3. Patients with Paget's disease of the nipple, lobular carcinoma in situ of the breast or atypical hyperplasia in the absence of DCIS are excluded
4. Pathologist must be able to state that the excision margins are clear, even after re-excision
5. No axillary lymph node involvement
6. Able to receive either treatment
