    Notes: Abstract: Lobular carcinoma in situ (LCIS) has gone from a rare form of mammary cancer to a marker of increased risk. Treatment options have undergone a corresponding change from ipsilateral mastectomy with axillary node dissection to observation once it became clear that the majority of patients did not progress to invasive cancer. However, recent events suggest a re-evaluation of LCIS management options. It is clear that even meticulous observation may fail to detect invasive cancer before systemic spread has taken place. This fact plus the identification of breast cancer genes have brought a renewed interest in prophylactic mastectomy. At the same time pathologists feel that it is possible to identify microscopic features of LCIS pointing to an increased likelihood of developing invasive cancer. As a result physicians are being asked to better quantitate risks for individual patients. Most patients with LCIS do not need bilateral mastectomies, but we are coming closer to identifying the minority that would be better served by prophylactic surgery.

    Notes: Abstract Background: We thought that observation for patients with lobular carcinoma in situ (LCIS) had been generally accepted by the mid-1980s. A questionnaire mailed to oncologic surgeons in 1988 revealed that 33% of the respondents still advised unilateral mastectomy, although a slim majority (54%) advised observation. New studies have been published in the intervening 8 years, and we decided it would be worth recirculating the 1988 questionnaire. Methods: The identical questionnaire was mailed to members of the same oncologic societies (Society of Surgical Oncology [SSO] and Society for the Study of Breast Disease), but changes in membership necessitated new mailing lists. Results: Observation has yet to be universally accepted by the oncologic community, but at this time 85% of the respondents suggest it as the preferred option for their patients. Conclusions: Recent studies have questioned some of the tenets laid down by Haagensen in 1978, but it appears clear that his formulation of LCIS as a marker of increased risk continues to gain ground over the original concept of inevitable progression to invasive disease.

    Notes: Lobular carcinoma in situ (LCIS) is not only a relative newcomer among breast lesions, but in its short span of 50 years in has gradually evolved from a rare form of breast cancer to being merely a marker of increased risk. This change has not been without controversy which persists to the present day, although there is now general agreement on the natural history of the disease.The present report represents an update on current thinking about LCIS as well as a review of the limited number of studies dealing with the natural history of the lesion when treated by biopsy alone. Invasive cancer will develop in approximately 20-25% of women with LCIS provided there is sufficient follow-up after biopsy. Precise estimates are not possible since LCIS is an asymptomatic lesion that never makes a mass or reveals itself on mammography. It is found only by biopsy and thus the population being followed is a selected one. Every study has shown that when invasive cancer develops, it is just as likely to appear in the contralateral as in the biopsied breast, and invasive ductal cancers are more common than lobular. Clearly, the small round cells with pale cytoplasm that characterize LCIS do not go on to invasion in the usual patient; rather they serve to identify women who are more likely to develop breast cancer. Such patients represent a clearly defined group at increased risk, and for that reason are ideal candidates for chemoprevention. If tamoxifen or some other agent proves to be effective, the remaining arguments favoring mastectomy for LCIS will finally disappear.
