Abstract
BACKGROUND This study examines changes in the management of ductal carcinoma in situ between 1995 and 1999 in the Australian State of Victoria. This period was before the release of Australian treatment recommendations. METHODS All new cases of ductal carcinoma in situ diagnosed between 1 April and 30 September in 1995 and 1999 were identified from the population cancer registry. Treating surgeons completed a questionnaire on the presentation and management of each case. In 1995, 64 out of 70 surgeons returned questionnaires for 137 cases (case response, 94%). In 1999, 68 surgeons treated 159 registered cases and 141 completed surveys were returned (case response, 89%). RESULTS More cases underwent an image-guided biopsy in 1999 (54%) than in 1995 (34%). Breast-conserving surgery (BCS) was used to treat 69% of cases in 1999 and 63% in 1995. The use of axillary procedures (clearance or sampling) for women treated by mastectomy decreased from 61% in 1995 to 30% in 1999. More patients treated with BCS had margins simply described as "clear" in 1995 (49%) than in 1999 (21%). In 1995, only 7% of cases treated with BCS had radiotherapy, and this was 25% in 1999. CONCLUSION In both 1999 and 1995, the majority of patients were treated by BCS, but only a minority received radiotherapy.

Abstract
BACKGROUND Breast ductal carcinoma in-situ (DCIS) is increasingly being diagnosed as a result of screening mammography and better pathological recognition. With this and the rising breast cancer incidence in Singapore, DCIS is poised to become a bigger part of surgical practice. Principles of screening, diagnosis and management of DCIS have also been rapidly evolving. Against this background, a clinicopathological audit of recent cases of DCIS in our centre was performed. METHODS Thirty-eight cases of DCIS diagnosed in the period 1997-2000 were retrospectively analysed. Histological examination and immunohistochemical studies for oestrogen and progesterone receptor expression were performed. RESULTS In the present study, DCIS was most common in the group of patients who were <50 years (58%) as compared to an American series' where the corresponding group were > or =60 years (36%). Compared to a previous local study a decade ago, the present series showed that: (i) DCIS constituted a higher proportion of all breast cancers (6.4% vs 3.7%); (ii) a larger proportion of patients had disease detected by mammography (47% vs 10%); (iii) conservative breast excision was the only definitive surgery in 39% of cases (vs approximately 30%); and (iv) the mean size of lesions is smaller (13.5 mm vs 24.4 mm). Histologically, 26% of tumours were high grade, 71% had necrosis while 32% were oestrogen receptor (ER) and progesterone receptor (PR) negative. High grade tumours were associated with the presence of necrosis (P = 0.018), ER negativity (P = 0.015) and PR negativity (P = 0.001). CONCLUSIONS This study reveals interesting trends of DCIS in Singapore. The sizeable proportion of hormone receptor-negative tumours may have implications for the hormonal adjuvant therapy of DCIS.

Abstract
Sentinel node biopsy (SNB) in primary breast cancer has been taken-up widely to avoid the morbidity attributable to axillary node clearance (ANC). Currently many issues surrounding SNB are undecided. This review summarises why some form of axillary surgery is required and presents data on all aspects of SNB including methodology, clinical results and problems that may delay the introduction of SNB as best practice for all patients with primary breast cancer. There is no long or medium term data relating to the consequences of replacing ANC with SNB, but the mechanisms and probable magnitude of both beneficial and detrimental effects are estimated. A low level of false negative results are inherent to the technique but it is demonstrated that SNB is likely to have an only marginal (0.6%) effect on survival that would be undetectable by clinical trials. Patient sub-groups particularly likely to benefit from SNB are identified.

Abstract
PURPOSE Rural women in the United States are at a documented disadvantage with regard to breast cancer detection, diagnosis, and treatment and generally do not receive state-of-the-art therapy. The objective of the study was to determine if, and to what extent, rural women were less likely to receive radiation therapy (XRT) following breast conserving surgery (BCS) for ductal carcinoma in-situ (DCIS). METHODS Our analyses were based on 1991-1996 data provided by the Surveillance, Epidemiology, and End Results (SEER) Program. Only women who were diagnosed with their first primary, microscopically confirmed DCIS breast cancer were included. BCS and XRT were defined according to SEER definitions. Multiple logistic regression was used in the analysis. RESULTS During this time period, 6,988 women were treated with BCS for DCIS, 50.1% of whom received XRT. In multivariate analysis, rural women in general (OR = 0.58) and younger women (<65) in particular (OR = 0.38) were less likely to receive XRT. Local availability of XRT was not associated with receipt among younger women, while older women without this availability were less likely to receive XRT (OR = 0.48). CONCLUSIONS Barriers to XRT following BCS for DCIS may be different between younger and older rural women relative to their urban counterparts.

Abstract
BACKGROUND Axillary dissection may be associated with significant morbidity and, while it is necessary in the treatment of invasive breast cancer, is not indicated for the treatment of pure ductal carcinoma in situ (DCIS), although it is being performed in a significant number of cases. The present study examined the incidence of elective axillary dissection in the treatment of DCIS cases detected in a mammographic screening programme over a 4-year period, and whether surgeons have changed their practice in this respect. METHODS BreastScreen Victoria records were examined retrospectively for the period from January 1995 to December 1998 to identify patients treated for DCIS. The incidence and indications for axillary surgery were investigated. RESULTS There were 579 cases of DCIS and 93 (16%) had some form of axillary surgery, which was thought to be inappropriate in 57 (10%), the latter being performed by 21 city surgeons and 20 rural surgeons. Before surgery, 36 (63%) cases were diagnosed by core biopsy or excision, and 21 (37%) had imaging and cytology alone for diagnosis. The rate of unnecessary axillary dissections dropped steadily from 14% in 1995 to 4% in 1998, a significant reduction (P = 0.01). CONCLUSION The incidence of axillary dissection for DCIS has dropped significantly over the last 4 years in Victoria, possibly due to increased awareness through education and guidelines. Surgeons are now more aware that in situ lesions do not need axillary dissection, and that axillary dissection should not be performed for breast cancer unless invasion has been proved histologically.

Abstract
The standard surgical treatment of the axilla in patients with early breast cancer is about to undergo a radical change. Although axillary dissection is an excellent procedure for both staging and local control, particularly in the clinically positive axilla, it has considerable morbidity and may understage a significant proportion of patients, because it will usually miss micrometastases that can occur in approximately 10% of 'node negative' patients. An increasing number of patients whose tumours are either non-invasive (ductal carcinoma in situ; DCIS), micro-invasive, tubular cancers or low-grade T1a tumours without lymphovascular invasion may be spared axillary surgery because the risk of axillary disease is 0-3%. Many studies, both prospective trials and large retrospective series, show that axillary radiotherapy alone provides similar local control rates to axillary dissection in patients with clinically negative axillas. Primary treatment of the axilla with radiotherapy alone, however, does not allow appropriate staging. Sentinel lymph node biopsy is being increasingly used in patients with breast cancer to provide this information. When a sentinel node is identified it is equal to or better than axillary dissection for staging the axilla and, if the node is positive, it will help select patients who should then proceed to further axillary surgery or axillary radiotherapy. Although sentinel lymph node biopsy is being rapidly adopted in many centres worldwide, the results of randomized controlled trials are needed before it can be recommended as the standard of care.

Abstract
BACKGROUND Mammographic screening for breast cancer not only reduces the overall mortality from breast cancer but allows greater opportunities for breast-conserving operations. The predicted degree of breast conservation is not being realized, but is increasing in centres that have published their results. METHODS The operative management of breast cancers diagnosed by BreastScreen Central and Eastern Sydney Screening and Assessment Service were compared between two time periods: January 1988-December 1992 (group 1) and January 1993-December 1995 (group 2). The rate of breast conservation, and other data were compared between the two periods. An attempt was made with multivariate analysis to identify some of the factors that made mastectomy rather than conservation more likely. RESULTS There were 723 cancers detected that were suitable for analysis (group 1, n = 273; group 2, n = 450). In group 1 the breast conservation rate was 42.9%; this increased significantly to 60.4% in group 2 (P < 0.001). The data were examined to determine if there was any other factor that had changed over the time periods which might account for the increased rate of breast conservation. The use of pre-operative diagnostic techniques such as fine needle aspirate cytology and core biopsy increased significantly. Multivariate analysis comparing the differences in patient age, diagnostic technique, tumour type, grade, size, location and lymph node status, both independently and compositely did not account for the increase in breast conservation in group 2. CONCLUSION The increase in breast conservation is due to other factors such as the surgeons' approach and patient attitude. The use of pre-operative, minimally invasive tissue sampling techniques is increasing.

Abstract
CONTEXT The Van Nuys (VN) classification system for ductal carcinoma in situ (DCIS) of the breast is a simplified morphology-based system that uses the presence of nuclear pleomorphism and comedo-type necrosis to stratify DCIS lesions into 3 prognostic groups. OBJECTIVE To determine if there is an underlying biological basis that correlates with the morphologic aspects of the VN classification system. DESIGN We evaluated the expression of markers implicated in the development of breast cancer (p53, ErbB2, and TAG-72) in DCIS classified with the VN system. Forty-five cases of pure DCIS were classified as 8 cases of VN1, 7 cases of VN2, and 30 cases of VN3. p53, ErbB2, and TAG-72 antigen expression was measured by immunohistologic means in each of the cases. RESULTS Nuclear accumulation of p53 was only observed in VN3 (30%). ErbB2 overexpression was found only in VN2 (14%) and VN3 (43%). TAG-72 expression was observed in all categories of lesions but was more frequent in VN2 (71%) and VN3 (70%) compared with VN1 (25%). It appears that overexpression of ErbB2 and p53 are features associated with the high-grade lesions. CONCLUSION The simplified VN classification system for DCIS has a clear underlying biological basis as evidenced by differential expression of tumor-associated antigens in each of the 3 morphologic categories. These differences may contribute to the differential clinical behavior of the separate groups.

Abstract
BACKGROUND Skin-sparing mastectomy with immediate transverse rectus abdominis musculocutaneous (TRAM) flap reconstruction is being used more often for the treatment of breast cancer. Mammography is not used routinely to evaluate TRAM flaps in women who have undergone mastectomy. We have identified the potential value of its use in selected patients. METHODS AND RESULTS We report on four women who manifested local recurrences in TRAM flaps after initial treatment for ductal carcinoma in situ (DCIS) or DCIS with microinvasion undergoing skin-sparing mastectomy and immediate reconstruction. All four patients presented with extensive, high-grade, multifocal DCIS that precluded breast conservation. Three of four mastectomy specimens demonstrated tumor close to the surgical margin. Three of the four recurrences were detected by physical examination; the remaining local recurrence was documented by screening mammography. The recurrences had features suggestive of malignancy on mammography. CONCLUSION We conclude that all patients undergoing mastectomy and TRAM reconstruction for extensive, multifocal DCIS should undergo regular routine mammography of the reconstructed breast. Our experience with this subgroup of patients raises concern about the value of skin-sparing mastectomy with immediate reconstruction for therapy. Adjuvant radiation therapy should be recommended for those patients with negative but close surgical margins.

Abstract
The frequency of diagnosis of ductal carcinoma in situ (DCIS) has increased in Australia, largely because of the national screening programme. Ductal carcinoma in situ presents a dilemma because of problems with its diagnosis and variations in reporting pathological and radiological findings, making it difficult to define optimal treatment and communicate information in a way that helps the patient understand the problems and make decisions. There is considerable inter-observer variation, particularly in differentiating low-grade DCIS from ductal hyperplasia, with or without atypia, but pathologists who participate in regular pathological review sessions vary less in their opinions. Mammography remains the main investigative tool for DCIS and the American College of Radiology has recommended standardized reports. A team approach is required for the removal and diagnosis of possible DCIS. Although the team may be best co-located in the one facility, this is not practical in many community hospital settings which lack on-site radiology and pathology services. The decision about how much breast tissue to remove will need to be made for each patient and depends on the size of the microcalcification and how suspicious the mammogram is for DCIS. We recommend the use of synoptic reports for DCIS, and we document the minimum factors that should be reported by pathologists. The evaluation and management of DCIS by a multidisciplinary team will allow the patient access to information required to make often difficult treatment decisions. In this paper, we review the literature about the natural history, pathology, cytology and radiology of DCIS and document the 20 critical steps required for the diagnosis of impalpable, mammographic microcalcifications suspected to be DCIS.
