- AIM: To survey the histopathological abnormalities in breasts of women who have undergone risk reducing mastectomy and to evaluate the effect of this measure on future breast cancer development. PATIENTS/METHODS: Between August 1995 and October 2006 100 consecutive women with a hereditary increased risk of breast cancer underwent prophylactic mastectomy (PM) at Malmö University Hospital. Fifty of the 100 women had no previous breast cancer. Fifty were BRCA1 or BRCA2 mutation carriers. All breast specimens have been examined histopathologically according to a prospective protocol. Follow-up data was collected from medical records and data in the Regional Cancer Registry. RESULTS: In the PM specimens abnormal lesions were found in 18 women (three with invasive cancers, eight in situ cancers and seven atypical hyperplasia). In previously healthy women lesions were more frequent after the age of 40 than among younger women (p=0.03). BRCA mutation carriers were more likely to present with ADH (atypical ductal hyperplasia)/ALH (atypical lobular hyperplasia) compared to the non-carriers/untested cases (p=0.01). After a median follow-up of 52 months (range 1-136 months) none of the women have developed breast cancer in the area of the prophylactically removed breast. CONCLUSIONS: Prevalent atypical or malignant lesions are relatively a common finding in PM specimens in asymptomatic women with hereditary increased risk of breast cancer. Such findings were significantly more common above age 40 in women without previous breast cancer. The risk of newly formed breast cancer after PM is small. The clinical importance of detecting a premalignant or preinvasive lesion in the breast at PM is still unclear.

Ipsilateral local recurrence in relation to therapy and morphological characteristics in patients with ductal carcinoma in situ of the breast
- 2000

- METHOD AND RESULTS: A standardized histopathological protocol has been designed, in which different histological characteristics of ductal carcinoma in situ (DCIS) are reported: nuclear grade (ng), growth pattern according to Andersen et al., necrosis, size of the lesion, resection margins and focality. Using this protocol a re-evaluation of a population-based consecutive series of 306 cases of DCIS has been done as well as a thorough clinical follow-up. After a median follow-up of 63 months, 13% have developed ipsilateral local recurrences, invasive and/or in situ. Ipsilateral local recurrence-free survival (IL-RFS) was significantly better for patients operated with mastectomy (ME) or breast conserving therapy (BCT) with radiotherapy (RT) than for patients operated with BCT without RT (5-year IL-RFS 96% vs 94% vs 79%, P<0.001). In the subgroup of BCT without RT there were significant differences in IL-RFS between histopathological subgroups: ng 1 + 2 (non-high grade) vs ng 3 (high grade; P=0.014), non-high-grade without comedo-type necrosis vs non-high-grade with comedo-type necrosis vs high-grade (the Van Nuys classification system; P=0.025). Growth pattern (not diffuse vs diffuse) and margins (free vs involved or not evaluated) showed a tendency (P=0.07 and 0.05, respectively) to be associated to IL-RFS. In contrast, no significant differences in IL-RFS were found in subgroups based on mode of detection, focality or size. Ninety-four per cent of the local recurrences after BCT appeared at the previous operation site. CONCLUSIONS: In the BCT without RT group, combinations of either non-high grade and not a diffuse growth pattern or non-high grade and free margins identified groups (constituting approximately 30% of the patients) were at low risk of developing ipsilateral recurrences (6-10%), compared to a 31-37% recurrence risk in the remaining groups during the observed follow-up time. The beneficial effect of post-operative RT for these low-risk groups can be questioned, and should be studied further.

Bilateral and multifocal breast carcinoma. A clinical and autopsy study with special emphasis on carcinoma in situ

Journal article (peer-reviewed)abstract
- Bilateral clinical breast carcinoma has been reported to appear in up to approximately 10% of patients with breast carcinoma. Increasing diagnostic activity has raised figures of bilaterality, mainly due to detection of lesions of the in situ type. Knowledge of the natural history of carcinoma in situ is incomplete and clinical implications are uncertain. In the present study bilateral lesions were analysed by extensive histological examination in the following groups of patients: (1) Forty-six women (median age 44 years) with clinical and mammographical unilateral invasive breast carcinoma, where the contralateral breast was removed at subcutaneous mastectomy (SCM) during the course of breast reconstruction, 24/46 (52%) had bilateral malignant lesions, four invasive carcinomas and 20 in situ carcinomas (two ductal carcinomas in situ /DCIS/, 15 lobular carcinomas in situ (LCIS), three both DCIS and LCIS). (2) Fifty-two women (median age 50 years) with a unilateral diagnosis of in situ carcinoma (32 DCIS, 16 LCIS, four both DCIS and LCIS), in whom both breasts were removed at SCM. 25/52 (48%) had bilateral malignant lesions, one invasive carcinoma, 24 in situ carcinomas (three DCIS, 18 LCIS, three both DCIS and LCIS). Twelve of 20 cases with LCIS (60%) were bilateral. Of 36 cases with DCIS, seven (19%) were bilateral. (3) The contralateral breast was removed at autopsy in 64 women previously unilaterally mastectomized (at median age 65) for invasive breast carcinoma. Fifteen of 64 (23%) had contralateral primary carcinoma at autopsy, four invasive carcinomas, 11 in situ carcinomas (six DCIS, five LCIS) and 8/64 (13%) had metastases in the breast. Multifocal malignant findings were also analysed in 47 SCM specimens after excisional biopsy for in situ carcinoma. In 35/47 (75%) further malignant lesions were present in spite of normal mammographic and clinical findings. Four were invasive and 31 had in situ lesions (16 DCIS, 10 LCIS, five both DCIS and LCIS): These findings may favour the hypothesis that some carcinomas in situ may remain silent or even regress. It is thus important to embark upon randomized trials to clarify the natural history of breast carcinoma in situ. Such a trial has been started in the southern region of Sweden.

Journal article (peer-reviewed)abstract
- In the city of Malmo, in southern Sweden, 1693 women were diagnosed as having breast carcinoma during 1976 through 1984. Of these, 167 women had pure in situ breast carcinoma (9.9%). One hundred and thirty-two had ductal carcinoma in situ (DCIS) alone or in combination with lobular carcinoma in situ (LCIS), intracystic carcinoma and/or Paget's disease of the nipple. Thirty-three had pure LCIS and two had pure intracystic carcinomas. The incidence of breast carcinoma in situ (CIS) in women 20 years of age or older was 18.7 per 10(5) woman years with high rates of DCIS for all ages above 40, whereas a decline in incidence rate was seen for LCIS in the postmenopausal age groups. The ratio of DCIS to LCIS was 4:1. Of the 132 patients with DCIS, 46% were asymptomatic and were diagnosed by mammography, 35% presented with clinical symptoms, and 19% of the cases were incidental findings in breasts operated on for benign lesions. Mammography had been performed on all patients with DCIS and contributed to diagnosis in 75%. Sixty-one per cent of all DCIS lesions had microcalcifications suspicious for carcinoma. Eighty-nine of 132 patients with DCIS underwent fine-needle aspiration biopsy (FNAB) before surgical biopsy. FNAB was suspicious or diagnostic for carcinoma in 57/89 (64%). Of 33 cases with LCIS all but one were incidental findings. In one of 28 cases with LCIS examined by mammography there was suspicion of carcinoma. Sixteen per cent of the patients with DCIS were treated by a breast-conserving operation (BCO), the remaining patients by mastectomy (ME) (52%) or subcutaneous mastectomy (SCM) (33%) with immediate reconstruction. Thirty-three per cent of the patients with LCIS were treated by BCO, the remaining patients by ME (18%) or SCM (49%) with immediate reconstruction. Only one patient had radiotherapy postoperatively. In 60% of all CIS cases where an excisional biopsy had been performed there were further foci of CIS in the final ME/SCM specimen. After a median follow-up of 7 years for the DCIS group, three patients out of 21 treated by BCO had invasive carcinoma appearing ipsilaterally. They were alive and without symptoms of recurrent disease 2.5 to 6 years following further surgery. One patient treated by SCM died from generalized ductal breast carcinoma. In the LCIS group (median follow-up 8 years) one patient out of 11 had an invasive tubular carcinoma diagnosed 4 years after BCO. Eight years later she was alive and well after bilateral SCM.
