Metaplastic carcinoma of the breast arising within complex sclerosing lesion: a report of five cases

HISTOPATHOLOGY, Issue 3 2000
Denley
Aims This study presents a series of five cases in which metaplastic carcinoma, predominantly low-grade adenosquamous carcinoma, of the breast is seen arising within a background of a complex sclerosing lesion. This association has been recognized previously but has not been documented in detail. This study describes the characteristics of the components present in each case and discusses the existing literature. This observation adds further evidence to support an association between some types of invasive breast carcinoma and sclerosing lesions of the breast. Methods and results Four of these cases were received as referral cases for opinion. The fifth was received as part of the routine surgical workload within our own institution. Two patients presented following mammographic screening and three symptomatically; their mean age was 62 years (range 49,68). The mean lesion size was 16 mm (range 7,24). All five lesions showed features of a complex sclerosing lesion/radial scar in the form of central sclerosis with elastosis and radiating benign entrapped tubules. One had associated benign papillary structures and two had focal benign squamous mletaplasia. Four cases showed coexisting but distinct areas of low-grade adenosquamous carcinoma with glandular and squamous epithelial differentiation in a spindle cell background. One case had associated undifferentiated spindle cell carcinoma. Detailed immunophenotypic characteristics of two cases are presented. Conclusions This series illustrates a postulated but previously unconfirmed association between an unusual form of metaplastic breast carcinoma (adenosquamous carcinoma) and complex sclerosing lesions. The mechanisms of induction of breast carcinoma are poorly understood but these observations further emphasize the potential for sclerosing lesion of the breast to be associated with, and possibly give rise to, invasive carcinoma of different types. The precise nature of the interaction between the pathological processes remains unclear. [source]


Using fear appeals to promote cancer screening,are we scaring the wrong people?

INTERNATIONAL JOURNAL OF NONPROFIT & VOLUNTARY SECTOR MARKETING, Issue 2 2006
Sandra C. Jones
There is debate regarding the use of fear appeals (emphasizing severe threats to health) in social marketing, to encourage preventive behaviours, such as screening for breast cancer. While it has been found that fear appeals may result in attitude and behaviour change there is also the risk of inciting inappropriate levels of fear, motivating the wrong audience or instigating maladaptive behaviour in the target group such as denial or defensive avoidance. This study examined the impact of an experimental threat manipulation for mammography screening on a group of women in regional Australia. The study found that varying the level of threat had no impact on stated intentions of the women to undergo mammographic screening. However, it also found that high-threat messages resulted in stronger negative emotional reactions and greater perceived susceptibility among younger women who are not the target group for screening in Australia. The results of this study emphasize the importance of limiting the use of high levels of threat in social marketing campaigns, and ensuring that campaigns are appropriately designed to specifically impact upon and motivate the target group.

Molecular markers and therapeutic targets in ductal carcinoma in situ

MICROSCOPY RESEARCH AND TECHNIQUE, Issue 1 2002
Gary P. Boland
Abstract Ductal carcinoma in situ (DCIS) of the breast is a premalignant condition which accounts for approximately 20% of all new breast cancers and up to 40% of neoplastic lesions detected by mammographic screening. Since recurrence is common after DCIS treated with breast conservation surgery, there is a need to determine molecular factors that predict recurrence. In parallel with this and with the finding that oestrogen receptor (ER) positive breast cancer can be prevented with anti-oestrogens, there have been recent advances in the understanding of the molecular biology of DCIS. Receptor coexpression in DCIS has been determined largely by immunohistochemistry. Animal models have provided evidence for the signalling pathways involved in the regulation and dysregulation of proliferation and apoptosis in both normal breast and in situ cancer. ER-negative DCIS has been shown to be hormone-independent. Blockade of the pathways involved in cell proliferation in ER-negative DCIS is possible and will be necessary to prevent ER-negative breast cancers if the goal of breast cancer chemoprevention is to be realistically achieved.

Life values before versus after a breast cancer diagnosis,

RESEARCH IN NURSING & HEALTH, Issue 2 2002
Claudia Lampic
Abstract The main aim of this study was to investigate whether women's life values change with a breast cancer diagnosis. In addition, associations between life values and anxiety/depression ratings were investigated. Life value changes were prospectively studied in 517 women recalled for further examination after attending mammographic screening, 38 of whom were diagnosed with primary breast cancer. Life values were assessed by a study-specific version of a life value questionnaire, including ratings of the perceived attainment and importance of seven life value dimensions. Three months after being recalled, women diagnosed with primary breast cancer reported a reduction of the attainment and the importance of Health. In addition, these women reported changes in the perceived importance of Responsibility and Involvement. High levels of anxiety and depression in particular were associated with large discrepancies between attainment and importance for some life values. This suggests that changes in the perceived importance of some life values may constitute one part of women's psychological adaptation to a breast cancer diagnosis. © 2002 Wiley Periodicals, Inc.

Status of Mammography after the Digital Mammography Imaging Screening Trial: Digital versus Film

THE BREAST JOURNAL, Issue 2 2006
D. David Dershaw MD
Abstract: Well-publicized results of the recent Digital Mammography Imaging Screening Trial (DMIST) have again shown that there is no clear advantage in mammographic screening of the general population with digital versus film mammography. However, several subgroups,women less than 50 years old, pre- or perimenopausal, and denser breasts,did better with digital mammography than with film. Data also suggest that women with the opposite characteristics might do better with film mammography. This article reviews the data of the four studies comparing digital and film mammographic screening. In addition, it describes the technology involved in the two types of mammographic image capture, the advantages and disadvantages of each type of imaging, and the future possibilities opened by digital technique. Because less than one-tenth of mammography units in use in the United States are digital, the availability of this technology to women undergoing screening and to physicians referring patients to screening sites is very limited. The author suggests that the quality of mammography, rather than the technique used to capture the image, is more important in selecting a mammography facility. For those who have a facility that offers both digital and film mammography, consultation on which type of imaging might be better for an individual woman would be appropriate. Because digital mammography from different manufacturers is based on differing technologies and because data comparing the advantages or disadvantages of these differing types of equipment are not available, it is impossible to recommend which type of digital mammography equipment is best for those undergoing mammography with these types of units.

A Multimodality Approach to the Diagnosis of Breast Hamartomas with Atypical Mammographic Appearance

THE BREAST JOURNAL, Issue 1 2001
Juan D. Berná MD
Abstract: The ultrasonographic appearance of breast hamartomas (BHs) is described and its diagnostic utility is discussed in this study of 27 women with mammographic findings both typical and atypical of BH. The role of computed tomography (CT) in the diagnosis of BH of atypical mammographic appearance is also analyzed. These 27 cases of BH were detected in women submitted to mammographic screening. Ages ranged from 45 to 65 years (mean age 52.6 years). In all cases physical and ultrasonographic examinations were carried out. CT studies were carried out in seven cases. Core biopsy was performed in 18 cases of lesions with a mammographic appearance atypical of BH. Lesions were palpable in 9 cases and nonpalpable in 18. Mammographic appearance was characteristic in nine cases. In 19 cases a hypoechoic solid mass with hyperechoic lines and/or bands was seen. This ultrasonographic image is suspicious of BH. Finally, both CT and core biopsy findings were of great help in the diagnosis of BH in the cases where mammographic and ultrasonographic studies were inconclusive. We consider that a combination of mammography, ultrasonography, CT, and core biopsy is fundamental for the successful diagnosis of breast hamartomas not seen in typical form in mammograms. [source]


TREATMENT FOR DUCTAL CARCINOMA IN SITU IN AN ASIAN POPULATION: OUTCOME AND PROGNOSTIC FACTORS

ANZ JOURNAL OF SURGERY, Issue 1-2 2008
Esther W. L. Chuwa
Background: Breast cancer is the most common cancer among Singapore women and ductal carcinoma in situ (DCIS) is believed to be the precursor of most invasive breast cancers. The incidence of DCIS has increased dramatically with mammographic screening, but its treatment remains controversial. Further, results of treatment for DCIS in Asians, and in particular Singapore women, are lacking. We review our institution's results treating a predominantly Chinese population with DCIS of the breast before the introduction of mammographic screening and aim to determine treatment outcomes and identify prognostic factors for disease recurrence. Methods: Between January 1994 and December 2000, 170 consecutive patients with DCIS were treated at our institution. One hundred and three (60.5%) were managed with breast conservation (17 with local wide excision alone and 86 with adjuvant irradiation following wide excision) whereas 67 (39.4%) underwent mastectomy. Of those who underwent wide local excision, 56 (54.3%) underwent re-excision for margin clearance. Overall, the axilla was surgically staged in 47 (27.6%) and no nodal involvement was found in all cases. Pathological specimens were reviewed by one of the authors. Median follow up was 86 months (range 4,151 months). Results: Sixty-two patients (36%) were asymptomatic at presentation whereas most (64%) presented with clinical symptoms; out of these more than half (54%) presented with a palpable lump. The median size of tumours was 13 mm (range 1.5,90 mm). Patients who underwent breast conservation surgery had oncologically more favourable lesions , with a significantly higher incidence of smaller and non-palpable lesions and lesions of lower nuclear grade. However, there was also a significantly higher incidence of local recurrence in this group. At the end of follow up, there were 12 patients (7.1%) who developed local recurrence and 8 patients (4.7%) developed contralateral disease. The crude incidence of all breast events (including both local failure and contralateral events) at 5 years was 5.6%. Median time to the development of any breast event (local recurrence or contralateral disease) was 60 months (range 12,120 months). The cumulative 5-year recurrence-free survival for patients who underwent breast conservation surgery was 94%. Factors influencing local recurrence rate were close or involved margins (,1 mm) and lack of adjuvant radiotherapy. There were no cancer-specific deaths during the period of follow up. Conclusion: Our results indicate that rates of cancer-specific survival were similar after mastectomy and breast conserving surgery. However, a close or involved margin (,1mm) and lack of adjuvant radiotherapy were associated with local recurrence, with margin status being the independent predictor for local recurrence. Our results reinforce that optimizing local therapy is crucial to improve local control rates in women treated with DCIS in our population. [source]


URBAN,RURAL DIFFERENCES IN THE MANAGEMENT OF SCREEN-DETECTED INVASIVE BREAST CANCER AND DUCTAL CARCINOMA IN SITU IN VICTORIA

ANZ JOURNAL OF SURGERY, Issue 11 2006
David L. Kok
Background: At least one-third of primary breast cancers in Australia are discovered by population-based mammographic screening. The aim of this study was to determine whether there were any differences in the surgical treatment of women diagnosed with breast cancer by BreastScreen Victoria between urban and rural populations and to investigate temporal changes in their pattern of care. Methods: An analysis of women diagnosed with breast cancer (invasive and non-invasive) by BreastScreen Victoria from 1993 to 2000 was conducted. Descriptive analyses of the proportion of women undergoing each surgical treatment type over time were carried out. Logistic regression was used to assess the effect of urban,rural residence on each treatment outcome while accounting for possible confounding factors. Results: Rural women with invasive breast cancer were less likely to undergo breast-conserving surgery (BCS) compared with urban women (odds ratio, 0.42; 95% confidence interval, 0.35,0.50). The same was also true for rural women with ductal carcinoma in situ (odds ratio, 0.53; 95% confidence interval, 0.29,0.96). This difference was independent of patient and tumour characteristics, including tumour size, surgeon caseload, patient's age and socioeconomic status. It also persisted over time despite a steady overall increase in use of BCS for both invasive and non-invasive cancers over the study period. Conclusions: Among Victorian women with screen-detected breast cancer, urban women consistently had higher rates of BCS compared with rural women despite increased overall adoption of BCS. Reasons for this disparity are still unclear and warrant further investigation. [source]


Combined radioguided occult lesion and sentinel node localization for breast cancer

ANZ JOURNAL OF SURGERY, Issue 7 2004
Joon Kim
Introduction: The incidence of non-palpable breast lesions requiring intraoperative localization has greatly increased, particularly because of the widespread use of mammographic screening. These lesions have previously been localized preoperatively using hook-wire or carbon track techniques. In the era of increasing acceptance of sentinel node biopsy (SNB) a separate procedure would be required for sentinel node localization (SNL). The present study describes an experience with ultrasound guided radionucleotide occult lesion localization (ROLL) as a reliable alternative that enables SNL synchronously. Methods: Twenty-two patients with proven breast malignancy on core biopsy were enrolled in the present study. Preoperatively, technetium-99m was injected around the lesion under radiological guidance. A ,-probe was then used to locate the lesion and guide its surgical removal. Complete excision was then confirmed immediately by verifying minimal residual radioactivity in the cavity wall tissue. Appropriate SNB then proceeded. Results: The primary breast lesion was identified in all cases except in one, where the radiotracer was injected into the wrong site, giving a miss rate of 1/22 (4.5%). The average size of the tumour was 13 mm (range 6,22 mm) and the closest margins ranged from 0 (1 patient) to 22 mm (mean 7 mm). Two patients had inadequate margins and required further excision giving a re-excision rate of 2/21 (9.5%). SNB specimens included a median of 3.7 nodes/patient Conclusion: Radionucleotide occult lesion localization/SNL is a simple, accurate and reliable method of combining localization of impalpable breast lesions with the localization required for SNB. The miss and re-excision rates compare favourably with the needle-wire systems and carbon tracking techniques. There are significant resource efficiency and time advantages. [source]
