Abstract
Context: Fine-needle aspiration cytology (FNAC) is a proven diagnostic technique for establishing the benign or malignant character of breast lesions. Several cytological grading systems have been proposed for grading of carcinoma breast, with results similar to histologic grades. Aims: This study sought to evaluate the prognostic value of FNAC in invasive ductal carcinoma of breast by correlating it with histological grade. Settings and Design: Tertiary care hospital, retrospective analytical study. Patients and Methods: One hundred and fifty cases of breast carcinoma that underwent modified radical mastectomy consequent to an FNAC diagnosis were included in the study. Robinson's grading system and Elston–Ellis modification of Scarff–Bloom–Richardson grading system were used to assign cytologic and histologic grades, respectively. Statistical Analysis: The cytological grades were correlated with the histological grades using χ2-test and Spearman's rank correlation coefficient. The individual features of the cytological grades were correlated with the histological grades using Kappa coefficient and χ2-test. Values were considered significant at P < 0.05. Results: A statistically significant association was observed between cytologic and histologic grades (r = 0.97; P < 0.01) with sensitivity and specificity, respectively, of 100% and 93.95% for cytological grade 1, 100% and 100% for cytological grade 2 and 100% and 100% for cytological grade 3. Also, a positive correlation was found between each feature of the cytologic grade and the histologic grade (P < 0.05). Among these, a better correlation was demonstrated by cytological features like cell uniformity (Kappa coefficient = 0.50) and appearance of nucleoli (Kappa coefficient = 0.52). Conclusions: Robinson's cytologic grading system is a reliable grading method on FNAC smears of cases of carcinoma breast. It correlates well with Elston–Ellis modification of Scarff–Bloom–Richardson grade in invasive ductal carcinoma of breast.

Abstract
AIMS AND BACKGROUND Breast carcinoma is a heterogeneous disease, the prognosis of which correlates with various prognostic factors. The aim of this study was to assess the prognostic significance of c-erbB-2 overexpression in breast carcinoma patients in association with other known prognostic factors. METHODS & STUDY DESIGN The relationship between immunohistochemical expression of the c-erbB-2 oncoprotein and various established prognostic factors such as tumor size, axillary node status, estrogen and progesterone receptor status, DNA ploidy, proliferation index, cathepsin D expression and histological grade in invasive ductal breast carcinoma is presented in this study. RESULTS Of the 93 ductal invasive carcinomas 22 (23.7%) were grade I, 51 (54.8%) grade II, and 20 (21.5%) grade III, and the majority (78: 83.9%) were 2-5 cm in diameter. Tumor metastases were identified in one or more lymph nodes in 55 (59.1%) patients, the remaining 38 (40.9%) patients being lymph node negative. According to the DNA histograms 40 (43.0%) tumors were aneuploid and 53 (57.0%) were diploid, and the majority of tumors had more than 4% of cells in the S phase of the cell cycle (83.9%). Expression of c-erbB-2 as shown by immunohistochemical intense membrane staining was present in 49 (52.7%) tumors. Cathepsin D-positive cytoplasmic granular staining and cathepsin D-positive stromal macrophages were found in 60 (64.5%) and 72 (77.4%) tumors, respectively. Univariate analysis showed that overall survival correlated significantly with axillary lymph node involvement and with estrogen and progesterone receptor status for each of the receptors separately and for their coexpression, and only marginally with c-erbB-2 overexpression. In mulitivariate analysis only axillary lymph node metastases and coexpression of estrogen and progesterone receptors were found to be independent and significant prognostic factors. CONCLUSIONS When patients were stratified according to c-erbB-2 expression it was shown that those with c-erbB-2 overexpression and grade II tumors, tumor size greater than 2 cm, high content of aneuploid cells and cathepsin D-positive stromal macrophages had a shorter long-term survival than c-erbB-2 negative patients.

Abstract
Clinical and pathologic features of 12 examples of so-called mucocele-like lesion, mucocele-like tumor, or intraductal carcinoma with mucous leakage are recounted. Similar alterations were noted in almost one half of the pure mucinous cancers and one fifth of mixed-mucinous cancers examined. This suggests that these lesions, particularly those characterized by mucinous intraductal cancer, may represent a histogenetic spec trum with overt mucinous cancers, even though all patients in this and other studies have remained disease-free for varying periods of observation. Although overall sur vival for pure mucinous cancers was only 58% at 15 years, it was still better than that (33%) found for women of the same cohort with not otherwise specified carcinomas. There are no contraindications to treat all mammary mucinous lesions conservatively. Int J Surg Pathol 1(4):213-220, 1994

Abstract
BACKGROUND Fine needle aspiration (FNA) is a quick, minimally invasive procedure for evaluation of breast tumors. The Scarff-Bloom-Richardson (SBR) grade on histological sections is a well-established tool to guide selection of adjuvant systemic therapy. Grade evaluation is possible on cytology smears to avoid and minimize the morbidity associated with overtreatment of lower grade tumors. AIM The aim was to test the hypothesis whether breast FNA from the peripheral portion of the lesion is representative of Scarff-Bloom-Richardson grade on histopathology as compared to FNA from the central portion. MATERIALS AND METHODS Fine-needle aspirates and subsequent tissue specimens from 45 women with ductal carcinoma (not otherwise specified) were studied. FNAs were performed under ultrasound guidance from the central as well as the peripheral third of the lesion for each case avoiding areas of necrosis/calcification. The SBR grading was compared on alcohol fixed aspirates and tissue sections for each case. RESULTS Comparative analysis of SBR grade on aspirates from the peripheral portion and histopathology by the Pearson chi-square test (χ(2) =78.00) showed that it was statistically significant (P<0.001) with 93% concordance. Lower mitotic score on aspirates from the peripheral portion was observed in only 4 out of 45 (9%) cases. The results of the Pearson chi-square test (χ(2) = 75.824) with statistically significant (P=0.000). CONCLUSION This prospective study shows that FNA smears from the peripheral portion of the lesion are representative of the grading performed on the corresponding histopathological sections. It is possible to score and grade by SBR system on FNA smears.

Abstract
BACKGROUND Hyaluronic acid (HA), a high-molecular weight glycosaminoglycan, has been considered to be involved in the growth and progression of malignant tumors in several experimental studies. The objective of this work was to evaluate the cytosolic HA content in breast cancer, its possible relationship with clinicopathological tumor parameters and steroid receptor status, as well as its potential prognostic significance. METHODS Cytosolic HA levels were examined by means of immunoradiometric techniques in 850 patients with invasive breast cancer. The mean follow-up period for these patients was 55.1 months. RESULTS Cytosolic HA levels ranged widely in tumors (4-59767 ng/mg protein; median: 4960). Statistical analysis showed that HA levels were significantly higher in younger patients (p=0.0001), as well as in premenopausal than in postmenopausal patients (p=0.001). HA levels were also significantly higher in ductal or lobular histological type than in other histological types (coloid, medullar or papillar types) (p=0.0001). Likewise, HA correlated significantly and positively with tumoral levels of PgR (r sub S: 0.11; p=0.001) in the all group of patients. In the subgroup of patients with ductal invasive type, HA levels were also significantly higher in well differentiated tumors and in diploid tumors. In addition, in this latter group of patients, HA levels in tumors correlated also positively and significantly with the either estrogen-inducible proteins: PgR (r sub S: 0.11; p=0.001), pS2 (r sub S: 0.117; p=0.008) and tPA (r sub S: 0.314; p=0.0001). On the other hand, significant association between HA intratumoral levels and relapse-free survival and overall survival in the overall group of patients was not found. However, high HA intratumoral levels were significantly associated with longer relapse-free survival in the subgroup of patients with ductal histological type tumors (p=0.01), as well as in those patients without any type of systemic adjuvant treatment (p=0.01). CONCLUSIONS Our results suggest that high intratumoral levels of HA may be associated with tumors of favorable evolution in certain subgroups of patients with breast cancer. Thus, HA may provide additional prognostic information to that given by other biochemical markers currently used in breast cancer.

Abstract
BACKGROUND Some investigators have suggested a decreased prognostic value for conventional prognostic factors over time in patients with breast carcinoma. The objective of this study was to assess the effect of prognostic factors on the risk of death in patients with breast carcinoma over a long follow-up. METHODS The authors assessed clinicopathologic prognostic factors in patients with early-stage breast carcinoma over a follow-up > 25 years and analyzed the variation of their effect on death in consecutive 5-year follow-up intervals. The study included 2410 women who primarily underwent complete surgical resection. Time-dependent variables were analyzed by using different multivariate models. RESULTS Four factors were related strongly to the risk of death in the first 5 years: tumor size, histologic grade, the number of involved axillary lymph nodes, and age at diagnosis. After 10-15 years of follow-up, only age at diagnosis was related to the risk of death. The effect of powerful prognostic factors, except age at diagnosis, on the risk of death was time limited, and no effects or very small effects were detectable after 10 years of follow-up. CONCLUSIONS Conventional and widely accepted prognostic factors may explain a significant portion of early deaths among patients with early-stage breast carcinoma, but they were of limited value to explain late mortality, that also may be influenced by late events, such as new primary malignancies and treatment complications.

Abstract
African-American women face a lower risk of being diagnosed with breast cancer as compared to Caucasian-American women, yet they paradoxically face an increased breast cancer mortality hazard. An increased incidence rate for early-onset disease has also been documented. This manuscript review summarizes the socioeconomic, environmental, genetic, and possible primary tumor biologic factors that may explain these disparities.

Abstract
BACKGROUND African American women have lower breast carcinoma survival rates than do Caucasian women. African American women often present with advanced-stage disease and more aggressive tumors as shown by histologic and laboratory-based prognostic factors. Aggressive tumor behavior may be responsible, at least in part, for the advanced stage and reduced survival rates. METHODS The authors investigated the correlation between survival and histologic grade, stage of disease, and tumor size for both African American and Caucasian women who were younger than age 50 years and age 50 years and older. The authors also investigated the distribution of grade within each stage group and the distribution of grade by tumor size. African American and Caucasian women were matched by stage, tumor size, and histologic grade. Survival was represented by 6-year breast carcinoma-specific survival rates. RESULTS Compared with Caucasian women, African American women, regardless of age, had proportionally more Grade III tumors and fewer Grade I and II tumors for all stages combined and for each individual stage group. Similarly, matched for tumor size, African American women had more Grade III tumors and fewer Grade I and II tumors compared with Caucasian women, except for tumors smaller than 1.0 cm. For nearly all combinations of stage and grade regardless of age, the 6-year breast carcinoma-specific survival rate was lower for African American women than for Caucasian women, although it did not always reach statistical significance. CONCLUSIONS Compared with Caucasian women, African American women, regardless of age, presented with proportionally more aggressive tumors for each stage of disease and for each tumor size above 1.0 cm as revealed by the histologic grade. Higher histologic grade may be a significant contributing factor to survival disadvantage for African American women.

Abstract
With the rising age of the population and the proposed extension of the breast screening programme to older women, increasing numbers of older patients are becoming eligible for breast conserving surgery and post-operative breast irradiation. Women over the age of 70 have traditionally been omitted from randomized controlled trials for assessing the role of breast radiotherapy after local surgery. The majority of trials suggest that local recurrence rates do decline with age. Similar conclusions are suggested by many non-randomized studies. Comparison of randomized and non-randomized studies is limited by differing extent of classifying tumour margins, nodal status, use of adjuvant systemic therapy, sample size, analytical approaches and duration of follow-up. Large randomized trials in older women are needed to assess whether, with careful attention to obtaining clear tumour margins, radiotherapy is required in low risk, ER positive, node negative breast cancer patients following wide excision and adjuvant tamoxifen. Within both randomized and non-randomized studies, only a few studies have failed to demonstrate an impact of age on recurrence rates following breast conserving treatment, with the majority finding a reduction in local recurrence rates with increasing age. Importantly for interpretation, no studies suggest that recurrence rates increase with age. The variation in analytical approaches and sample sizes are such that the variety of conclusions is not surprising. The results are compatible with a tendency for local recurrence rates to fall with age, but the variability is such that one cannot quantify this change with any precision.

Abstract
PURPOSE To evaluate a new prognostic factor of breast cancer, bone marrow micrometastases which was detected by RT-PCR for mammaglobin, a sensitive molecular marker of breast cancer, was examined. MATERIALS AND METHODS One hundred and eleven samples from stage I-III breast cancer patients were examined. Bone marrow micrometastases and clinicopathological parameters, which were age, tumor size, lymph node metastasis and status of the estrogen receptor, were evaluated for the prognostic factor by statistical analysis. RESULTS Median follow-up time was 21.1 months. Thirty-three (29.7%) out of 111 samples were RT-PCR positive. Eight cases (24.2%) in this group showed recurrent lesions in the distant organs. Whereas six (7.7%) out of 78 RT-PCR negative patients had distant recurrences. In the premenoposal patients, and in the patients with axillary lymph node metastases, RT-PCR positive cases showed significantly higher distant recurrent rate. Bone marrow micrometastases, axillary nodal status, and estrogen receptor were independent prognostic factors for breast cancer by both univariate and multivariate analysis. CONCLUSIONS Bone marrow micrometastases detected by RT-PCR for mammaglobin can be a useful predictive marker for early distant recurrence of breast cancer.

Abstract
BACKGROUND Activation of Met, the receptor for scatter factor/hepatocyte growth factor, is associated with mitogenesis, motogenesis, and decreased cell adhesion. Elevated expression of Met has been shown in advanced cases of carcinoma of the prostate, stomach, pancreas, and thyroid. The authors previously demonstrated that Met expression is an independent prognostic marker associated with decreased survival in patients with breast carcinoma. METHODS Expression of Met in 113 archival breast carcinoma specimens from patients with axillary lymph node negative invasive ductal carcinoma was evaluated using a standard immunoperoxidase technique. Cases were scored by two pathologists using an H-score algorithm and then analyzed for correlation with known prognostic factors and survival. RESULTS Expression of Met showed a bimodal distribution with 25% of cases showing high levels of expression. In contrast to previous studies, the results of the current study showed a significant association between Met expression and nuclear and histologic grade. The 5-year survival rate for Met negative patients with tumors with low Met expression was 95% in this cohort, compared with 80% for patients with tumors showing high Met expression. Patients whose tumors had a high level of Met expression were found to have a 5-year relative risk (RR) of dying of metastatic disease of 5.05 (P = 0.03) independent of patient age and tumor size. Combined analysis of Met and nuclear grade resulted in a marked increase in independent predictive value (RR = 33.4; P < 0.01). CONCLUSIONS The results of the current study found that high levels of Met expression were associated with death due to metastatic disease in patients with axillary lymph node negative breast carcinoma. Expression of Met may be a useful prognostic indicator of more aggressive disease in patients whose prognosis is not easily stratified by current histopathologic markers.

Abstract
The purpose of this study was the evaluation of the necessity of routinely applied postoperative radiotherapy in a highly selected patient-group after breast conserving surgery. Between 1983 and May 1994, 356 women over 60 years of age with Stage I or II breast cancer were treated by quadrantectomy and axillary dissection followed by either adjuvant irradiation or no radiotherapy. We have analysed our data retrospectively to investigate whether irradiation has any benefit in elderly patients with respect to locoregional recurrence rates. After a median follow-up of 60 months the multivariate model revealed lymph node status (p = 0.002) as highly significant with regard to local recurrence free survival. We were not able to identify a positive effect of adjuvant irradiation in patients with negative lymph nodes and positive receptor status: both patient groups with or without irradiation had similar locoregional recurrence rates of 3%. In a subgroup of patients who were lymph node negative, receptor positive, and received adjuvant tamoxifen therapy, the local recurrence rates were as low as 2% in both groups. Concerning these results it may be possible to avoid the morbidity and potential psychological side effects of radiotherapy in breast cancer patients over 60 years of age treated by breast conserving surgery (T1, N0, positive hormone receptor, adjuvant tamoxifen) without increasing risk of locoregional recurrence. These data have to be confirmed in a prospectively randomized fashion.

Abstract
The risk of dying from breast cancer differs between racial groups, and the reason for this racial difference is unknown. In this paper, we hypothesize that racial differences in breast cancer mortality may be due to racial differences in the metabolism of drugs used to treat women with breast cancer. Racial differences in the metabolism and effectiveness of other commonly used drugs have been described, and these differences are thought to result from genetic differences in the cytochrome P450 enzyme system. Tamoxifen, widely used for breast cancer treatment, is metabolized by the cytochrome P450 system. Preliminary evidence from human studies suggests that this agent is less effective in non-whites than whites; however, more definitive studies are needed. A better understanding of racial differences in cytochrome P450 drug metabolism and subsequent effectiveness will lead to better breast cancer treatment for all women.

Abstract
This study was undertaken to evaluate our ability to detect multiple molecular markers of prognosis and response to treatment in fine needle aspirates (FNA) from patients with primary breast carcinomas. 147 patients with operable primary breast carcinomas who had been recruited to a randomized trial of primary medical therapy (PMT) versus adjuvant chemoendocrine therapy were analysed. FNAs were taken prior to therapy and from this multiple slides were produced using cytospin cytocentrifugation and stored at -80 degrees C for subsequent immunocytochemical analysis (ICA). ICA was performed for oestrogen receptor (ER), progesterone receptor (PgR), p53, Ki67, and Bcl-2. Part of the aspirate was snap frozen and used for flow cytometric analysis of ploidy and S-phase fraction (SPF). In a subgroup of 50 patients who had surgery prior to systemic therapy, as well as FNAs, sections were also taken from paraffin-embedded blocks and stained by ICA for ER, PgR and p53 for validation. In these patients ER was additionally measured by enzyme immunoassay (EIA) from frozen tissue taken at surgery. ER, PgR, p53, Bcl-2, and Ki67 were successfully detected by ICA while ploidy and SPF were successfully measured by flow cytometry from FNA material. The percentage positive values obtained were reasonable and as follows: 74% for ER, 70% for PgR, 36% for p53, 80% for Bcl-2,68% of tumours were aneuploid and 32% diploid. Significant relationships between these measurements were observed in accordance with expectations. The concordance for ER, PgR, and p53 from FNA when compared to ICA of matching histological sections was 91.5%, 75.5%, and 75% respectively. For ER the concordance between measurement by ICA of cytological and histological samples and by EIA of frozen tissue was 82.5% and 84% respectively. These results indicate that multiple molecular markers can be adequately tested on cytological preparations from primary breast tumours. These markers can be used to determine prognosis and predict response to PMT.

Abstract
This study examines the influence of six patient characteristics (age, race, socioeconomic status, comorbidities, mobility and presentational style) and two physician characteristics (medical specialty and years of clinical experience) on physicians' clinical decision making behaviour in the evaluation treatment of an unknown and known breast cancer. Physicians' variability and certainty associated with diagnostic and treatment behaviour were also examined. Separate analyses explored the influence of these non-medical factors on physicians' cognitive processes. Using a fractional factorial design, 128 practising physicians were shown two videotaped scenarios and asked about possible diagnoses and medical recommendations. Results showed that physicians displayed considerable variability in response to several patient-based factors. Physician characteristics also emerged as important predictors of clinical behaviour, thus confirming the complexity of the medical decision-making process.

Abstract
To analyse the clinical significance of the presence of androgen receptors (AR) in breast carcinomas, clinical and histological parameters of 153 primary breast carcinomas (median follow-up 46 months) were examined. Oestrogen (ER) and progesterone receptor (PR) levels were determined in cytosol preparations using enzyme immunoassay assays and in cryostat sections by immunohistochemistry. AR and Ki-67 levels were only determined immunohistochemically. Data were analysed by uni- and multivariate models. 94/153 (61%) breast carcinomas were ER+ PR+ AR+, while 14 cases were only positive for AR. All grade III tumours (n = 17) were steroid receptor negative and 14 (76%) of these cases demonstrated high Ki-67 values suggestive of more aggressive behaviour. Strikingly, 14 ductal carcinomas negative for ER and PR were positive for AR. In univariate analysis, AR as well as ER, tumour size, lymph node status, grade and Ki-67 proved to be significant prognostic factors for disease-free survival (DFS). Multivariate analysis, however, showed lymph node status, tumour size and ER status to be the only independent prognostic factors for DFS within this model. We conclude that simple histological and cell biological parameters, including AR, can be used to select high- and low-risk patients at the time of primary surgery and can provide valuable information on treatment options.

Abstract
Fine-needle aspiration (FNA) biopsy is increasingly used in the diagnosis and biological characterization of breast carcinomas in patients who receive preoperative chemotherapy. In this context, nuclear cytologic grade supplemented by DNA content could play an important role in the morphologic assessment of breast cancer. In this study, DNA ploidy pattern, analyzed by flow cytometry on FNAs from 92 primary breast carcinomas, was related to cytologic nuclear grade. Twenty-seven samples were cytologic grade 1, 33 were grade 2, and 32 were grade 3. Ploidy correlated with cytologic nuclear grade (P = 0.0001). Thirty percent of grade 1, 55% of grade 2, and 84% of grade 3 tumors were DNA aneuploid. For 30 of the 92 FNAs, it was possible to compare nuclear cytologic grade with the corresponding histologic grade using the Scarff, Bloom, and Richardson system. A high concordance (80%) between nuclear grade on FNAs and histologic grade was found. DNA flow cytometry in combination with nuclear cytologic grade might represent additional information for the characterization of breast cancer diagnosed by FNA.

Abstract
BACKGROUND With the advent of screening mammography more breast cancer will be detected at an earlier stage, apparently confined to the breast with no nodal involvement. However, 30% of these will recur due to micrometastases present at the time of diagnosis. Chemotherapy and tamoxifen have been shown to improve disease-free survival in axillary node-negative patients but not overall survival. In the search for a useful predictor of breast cancer recurrence the relationship between c-erbB-2 expression and recurrence and survival was examined. METHODS Eighty-eight axillary node-negative breast cancer patients were followed up for at least 5 years. RESULTS There was a significant relationship between c-erbB-2 expression and both tumour recurrence (P<0.001) and poorer survival (P=0.003). In a Cox multiple regression analysis, c-erbB-2 staining remained the only significant prognostic variable for recurrence (P=0.002) and survival (P=0.032). Tumour recurrence in c-erbB-2-positive cases tended to occur early in the course of follow up and was associated with poorer survival. CONCLUSION C-erbB-2 was found to be a useful prognostic indicator for early recurrence and poorer survival in axillary node-negative breast cancer patients.

Abstract
DNA ploidy and S-phase fraction are considered to be prognostic variables in breast carcinoma. DNA content of 35 cases of breast carcinoma of varying histologic types and nuclear grades was analyzed by flow cytometry and image analysis in both fresh and formalin-fixed, paraffin-embedded tissue. Fresh cell and deparaffinized nuclear suspensions were used for flow cytometry. Fresh and deparaffinized tumor tissue samples were used for image analysis. The results of analysis for DNA ploidy, DNA index of DNA aneuploid Go/G1 peaks, and S-phase fraction were compared in different tissue preparations for both techniques. The two techniques produced comparable DNA ploidy results with both fresh and formalin-fixed, paraffin-embedded tissue. Sensitivity for detection of DNA aneuploidy was somewhat greater by image analysis, particularly in deparaffinized tissue. There was 89% agreement in detection of DNA aneuploidy by flow cytometry in fresh and paraffin-embedded, formalin-fixed tissue; the coefficients of variation of the DNA diploid Go/G1 peaks were much wider in the latter. In image analysis there was 91% agreement between fresh and fixed specimens. Agreement between the flow cytometry and image analysis in fresh specimens was 91%; in deparaffinized nuclear suspensions it was 94%. There is a high degree of correlation between the values of DNA index of DNA aneuploid Go/G1 peaks; the estimates of S-phase fraction are much more variable. Results also show a good correlation of the DNA ploidy with the nuclear grades.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Splice variants of CD44 expressed in a metastasizing cell line derived from a rat pancreatic adenocarcinoma have been shown recently to confer metastatic potential onto non-metastasizing rat pancreatic carcinoma and sarcoma cell lines. Homologues of these variants have also been detected in a variety of human malignancies. Using antibodies raised against a bacterially expressed fusion protein containing variant CD44 sequences, we have explored the expression of variant CD44 glycoproteins on tumors of the female breast. The material examined included normal tissue, hyperplastic lesions, 103 primary invasive mammary carcinomas, 10 in situ carcinomas, 12 local recurrences and 18 lymph node metastases. Using a polyclonal serum directed against several variant CD44 epitopes, normal mammary epithelia as well as ductal hyperplasias were negative for these splice variants, while the variant CD44 epitopes were detectable in all but six of the primary invasive carcinomas. From the reaction with various monoclonal antibodies and polyclonal sera specific for individual epitopes it is obvious that the tumors predominantly express CD44 variants encoded by exons v5 to v7. Interestingly, all investigated lymph node metastases reacted positively with the variant-specific antibodies, in contrast to primary tumors which reacted in 54% to 86% of the cases, depending on the antibody used. Statistical analysis revealed a significant correlation between expression of variant exons v3/v4 and v6 and increased tumor grade (p = 0.001 and p < 0.05, respectively; Fisher's exact test). Exon v6 is carried by the variants which confer metastatic capability in the rat. These results indicate that the expression of the CD44 variants is upregulated in mammary carcinomas and is closely linked to tumor anaplasia.

Abstract
BACKGROUND The histologic grade of a tumor provides prognostic information in addition to that provided by stage of disease. Poorly differentiated tumors are known to pursue a more aggressive course than their well differentiated counterparts. METHODS The frequency of grading and the relationship of grade to outcome was investigated for 793,649 cases of cancer from 15 anatomic sites as recorded in the Surveillance, Epidemiology, and End Results Program. RESULTS For all cancers, the frequency of grading increased from 1973 to 1987 and varied by anatomic site and histologic type. Survival decreased with advancing grade, and within each stage, grading separated cases into at least three distinct prognostic subgroups. For some cancers, regional stage cases assigned Grade 1 or 2 had higher survival rates than did localized stage cases assigned Grade 3 or 4. Therefore, grading allowed the identification of high and low risk subgroups within each stage grouping. CONCLUSIONS The tumor grade was a strong prognostic indicator for cancers of the urinary bladder, endometrium, and prostate--sites most often graded by pathologists. The histologic grade was also an important determinant of outcome for cancers of the brain, soft tissue, and breast; however, only a small percentage of these tumors were graded. The results are important because no common criteria for grading were established among the many contributing pathologists. Therefore, observer variation did not alter the known relationship of histologic grade to outcome. This review demonstrates that the histologic grade is a strong predictor of outcome that refines the prognostic information provided by the stage of disease.

Abstract
Large cooperative clinical trials such as those conducted by the National Surgical Adjuvant Breast and Bowel Project (NSABP) require measures for assurance of quality and consistency of their pathologic findings. The NSABP experience indicates that these issues may in large part be resolved by a central or headquarters review of pathologic materials submitted by institutional pathologists. This cooperation is implicit with participation in NSABP protocols, and its importance is emphasized at annual NSABP meetings. Assessments of gross characteristics of tumors and total number of lymph nodes and number with metastases used in analyses are performed by institutional pathologists and may be confirmed if necessary from routine surgical pathology reports or special D-1 forms submitted to the central pathology headquarters. The microscopic assessments by headquarters pathologists are performed without knowledge of clinical events and require preliminary training. The requirement of preliminary training emphasizes use of established criteria for the many qualitative and quantitative evaluations required. In some studies there may be as many as 35 quantitative evaluations. Agreement of findings of at least 90% with other experienced members of the pathology center or on subsequent individual re-review is required before an individual's assessments are accepted for analyses. Studies performed with limited pathologic material require assurance that members of the test cohort exhibit similar pathologic and clinical characteristics with those excluded from participation. Those performed without microscopic sections require confirmation that the material used contains adequate viable tumor tissue. This algorithm has resulted in a consistent demonstration of pathologic characteristics that affect diagnosis, prognosis, and treatment of patients with breast cancer.

Abstract
BACKGROUND S-phase fraction (SPF) predicts the prognosis of patients with breast cancer independently of tumor size, axillary metastasis, estrogen receptor (ER) and progesterone receptor (PgR), and patient age. Whether SPF is best measured by DNA labeling index (SPF-LI) or by flow cytometry (SPF-Flow) and what is the relative efficacy of SPF versus histopathologic characteristics for prognosis have remained unanswered questions. METHODS The authors studied 845 women with Stages I-II disease classification for years 1975-1990 with end results data, who were treated surgically with axillary lymph node dissection by an in vitro DNA labeling index protocol with tritiated thymidine or 5-bromo-2'-deoxyuridine and whose SPF was measured microscopically. Nuclear size was estimated with a calibrated optical grid as less than 11 microns, 11-14 microns, or greater than 14 microns. DNA flow cytometry was performed on fresh or paraffin embedded tissue; ER and PgR were performed by cytosol assay. Kaplan-Meier survival plots and multivariate analysis were used for comparisons. RESULTS Tumor size, axillary lymph nodal status, SPF-LI, nuclear size, and ER all related strongly to breast cancer specific survival and relapse free survival. PgR was less effective. Lymph node status and tumor size predicted long term survival; differences for other variables largely disappeared by 10 years. By multivariate analysis, axillary lymph node status, tumor size, and ER were independently prognostic for disease specific, relapse free survival. A strong trend was found for nuclear size. PgR, DNA ploidy, and SPF did not contribute to prognosis independently. Nuclear size was the strongest independent predictor in patients with negative axillary lymph nodes. CONCLUSIONS The number of positive axillary lymph nodes, tumor size, ER, and nuclear size were the strongest predictors of prognosis for patients with breast cancer. Only tumor size and lymph node status predicted the long term risk of metastasis.

Abstract
Two of the most important microscopically derived morphologic prognostic factors for breast carcinoma patients are histologic type of tumor and nuclear grade. The recent literature stresses the importance of including these parameters in the surgical pathology report, yet there is little information in the cytology literature regarding the reporting of the nuclear grade of breast carcinomas from fine-needle aspirate biopsies (FNAB). In this retrospective study, we examined 104 ductal carcinomas of the breast in order to determine whether the FNAB derived nuclear grade and morphologic aspects of histological grading such as tubule formation and mitoses could accurately correlate with the same parameters on the tissue specimens. There was a correlation of 87% between the nuclear grade assigned by FNAB and the nuclear grade assigned to the tissue sample. Both the Diff-Quik and the Papanicolaou staining methods were assessed in this study and both gave comparable nuclear grade results. Tubule formation was difficult to assess on the cytologic samples and mitoses showed no correlation between cytologic and tissue specimens. The FNAB sample was not representative of the tissue nuclear grade in only 4.8% of the cases. Nuclear grade is especially important in patients treated with chemotherapy prior to definitive therapy for breast carcinoma. We conclude that the nuclear grading of breast carcinomas is performed with ease, correlates well with tissue nuclear grade, and, as a fundamental cytologic parameter, should be included in the fine-needle aspirate biopsy report whenever possible.

Abstract
To determine cytomorphological characteristics of proliferative lesions of breast duct epithelium, we reviewed fine-needle aspiration (FNA) smears of 11 cribriform and micropapillary, low nuclear grade, ductal carcinomas in situ (DCIS), nine atypical ductal hyperplasias (ADH), and 10 florid or moderate ductal hyperplasias (DH) without atypia. These breast lesions presented as a palpable mass in 16 patients or were detected by diagnostic imaging in 14 patients. Cytological findings evaluated were cellularity, cell composition, architectural pattern (including presence and shape of intercellular spacing and cell characteristics of epithelial cell groups), nuclear diameter and pleomorphism, chromatin pattern, and number of single epithelial cells. Smears also were evaluated by cytological criteria only, using the scoring system of Masood et al. Based on our study's use of cytological and architectural features combined, the FNA diagnoses were as follows: of the 11 DCIS cases eight were carcinoma and three were inconclusive: proliferative epithelium (ADH v DCIS); of the nine ADH cases two were carcinoma and seven were inconclusive: proliferative epithelium (ADH v DCIS); and of the 10 DH cases four were DH, two were suspicious for carcinoma, and four were inconclusive: proliferative epithelium (DH v ADH). Using the cytological scoring system alone, of the 11 DCIS cases one was classified as carcinoma, five as ADH, and five as DH; of the nine ADH cases one was classified as carcinoma, three as ADH, and five as DH; and of the 10 DH cases four were classified as ADH and six as DH. This study shows that the application of both cytological and architectural criteria to the interpretation of FNA smears is more reliable than cytology alone in the identification of proliferative breast lesions and low-grade carcinoma. However, overlapping features between DH and ADH as well as ADH and low-grade carcinoma exist making separation of some of these lesions difficult. Aspirates of DH and ADH may display many single epithelial cells, mimicking low-grade carcinoma. However, a diagnosis of low-grade carcinoma can be made with confidence if the aspirates are cellular with many single atypical epithelial cells and lack an admixture of benign cellular elements. Architectural and cytological characteristics of proliferative duct epithelium, as evaluated in histological sections, are well represented in aspiration smears and should aid in the identification of these lesions.

Abstract
Increasing interest has been focused on DNA ploidy, hormone receptor status and tumour size as prognostic factors in node-negative breast cancer. We analysed these factors in patients operated on for primary invasive breast cancer between January 1981 and December 1987 in a prospective study of 248 women with no involved axillary nodes and 188 women with positive nodes followed until 15 April 1989. Oestrogen or progesterone receptor negativity, aneuploidy and tumour diameter exceeding 20 mm were studied as negative prognostic signs in life table analyses and Cox proportional hazards models of corrected survival. Corrected survival decreased with increasing number of negative signs. Three to four signs yielded a statistically significant, two- to threefold higher risk than the others. Survival estimates by life table analyses differed by 20% at 5 years. In the whole group, women with three or four negative factors had a relative risk of dying from their disease more than twice that of the others. Women with no involved nodes and with three or four negative factors had a risk of dying from breast cancer similar to that of node-positive women with fewer than three.

Abstract
In this study of 136 breast cancers with medullary features (MC), registered in the Danish Breast Cancer Cooperative Group (DBCG) from 1982 to 1987, we confirmed the prognostic importance of a new definition of medullary carcinoma of the breast (MC newdef) which was recently proposed by us, deduced from a previous study of a corresponding tumour material (DBCG 77-82). However, the individual histological criteria did not have the same prognostic importance as in our previous study, although prognostic trends were the same. To further improve and validate the diagnostic criteria, we combined the two populations and performed a multivariate Cox regression analysis. In the final Cox model, four histological parameters retained positive prognostic importance: (1) predominantly syncytial growth pattern, (2) no tubular component, (3) diffuse stromal infiltration with mononuclear cells and (4) sparse necrosis. We propose that these criteria are emphasized in the histological diagnosis of medullary carcinoma of the breast.

Abstract
The biological behavior of breast cancer supports the impression that it is often a systemic disease which can recur many years after the treatment of the local lesion. Since 35% of patients without axillary nodal metastasis will have recurrence of the disease after mastectomy, prognostic indicators are necessary to identify the high-risk patients to allow a more rational adjuvant therapy. We studied the prognostic value of fatty tissue invasion, perineural involvement and lymphatic and venous peritumoral embolization in T2NOMO primary breast carcinomas. Fifty-three patients were studied after initial treatment (only Halsted mastectomy). They were divided into two groups: A (control), with 25 patients with 15 years of survival without clinical and laboratory evidence of metastasis, and group B, with 28 patients who developed metastasis after initial treatment. The results were analysed by the chi-square test (p < 0.05). The fatty tissue invasion was identified in 56.0% and 78.5% in the A and B groups respectively, while venous embolization was only detected in 8.0% of the group A tumors and in 10.7% of those in group B. Neither showed significant variation when analyzed according to the chi-square test. Lymphatic embolization and perineural involvement were found respectively in 36.0% and 40.0% in the group A tumors and in 67.8% and 71.4% of those in group B, exhibiting a significant statistical variation. When analysing the histopathological characteristics in the pre- and post-menopausal patients, the chi-square test disclosed that lymphatic embolization and perineural involvement had a significantly higher incidence only in premenopausal patients in group B.

Abstract
PURPOSE Women with Stage I-II invasive breast cancer who present with gross multicentric disease or diffuse microcalcifications have a significant risk of breast recurrence when treated with conservative surgery and radiation. The purpose of this report is to present the results of mastectomy in this group of patients. METHODS AND MATERIALS Between 1982 and 1989, 88 patients with clinical Stage I-II breast cancer who presented with clinical and mammographic evidence of gross multicentric disease or diffuse microcalcifications underwent modified radical mastectomy. Median followup was 4 years for the 57 patients with gross multicentric disease and 5.6 years for 31 patients with diffuse microcalcifications. At the time of mastectomy, 42% of patients were found to have positive axillary nodes. Following mastectomy, 15 patients received post mastectomy radiation and 35 patients received adjuvant systemic chemotherapy. RESULTS When compared to a group of 1295 patients with unifocal, Stage I-II breast cancer, treated with conservative surgery and radiation during the same time period, patients with gross multicentric disease and diffuse microcalcifications had a significantly higher incidence of > or = 4 positive nodes, patients with gross multicentric disease had a lower incidence of positive resection margins following mastectomy and patients with diffuse microcalcifications were younger. The 5-year actuarial risk of an isolated local-regional recurrence was 8% for patients with gross multicentric disease or diffuse microcalcifications and 7% for patients with unifocal disease. Patients with gross multicentric disease or diffuse microcalcifications and > or = 4 positive axillary nodes who did not receive post mastectomy radiation had an increased risk for local regional recurrence. There were no significant differences in the 5-year actuarial overall or relapse-free survival (88% and 73% gross multicentric disease, 97% and 86% diffuse microcalcifications and 90% and 79% unifocal disease), freedom from distant metastasis (76% gross multicentric disease, 90% diffuse microcalcifications, 86% unifocal disease) or incidence of contralateral breast cancer (10% gross multicentric disease, 13% diffuse microcalcifications, 8% unifocal disease) among the three groups. CONCLUSION The present study demonstrates no increased risk of local-regional recurrence in patients with gross multicentric disease or diffuse microcalcifications undergoing mastectomy in contrast to the increased risk of breast recurrence in patients with gross multicentric disease undergoing conservative surgery and radiation. Indications for post mastectomy radiation include > or = 4 positive nodes or close or positive surgical margins. Despite a significantly higher incidence of > or = 4 positive nodes, patients with gross multicentric disease and diffuse microcalcifications have a 5-year actuarial overall and relapse-free survival comparable to a group of patients with unifocal disease treated with conservative surgery and radiation.

Abstract
Nuclear grade (NG) and S-phase fraction (SPF) are established independent prognostic variables for ductal breast carcinomas. Nuclear grade can be assigned by a pathologist in a simple fashion during histopathologic evaluation of the tumor, while SPF requires flow cytometric evaluation of tumor samples. This prospective study was undertaken to determine whether elevated SPF could be predicted from NG alone and how NG and SPF correlate with c-erbB-2 expression. Eighty-two breast carcinomas of ductal type were assigned an NG of low (grade 1 or grade 2) or high (grade 3). S-phase fraction was recorded initially from fresh-frozen tissue samples and was designated as either low SPF (below the value designated as the cutoff for elevated SPF) or high SPF (a value at or greater than the cutoff value). On fresh tissue the NG predicted the range of SPF (low or high) in 89% of cases. Four percent of the cases that did not correlate could definitely be attributed to sample error. The remaining 7% that did not correlate could have been due to sample error, specimen quality, or tumor heterogeneity, as demonstrated by reversal of SPF range as performed on paraffin blocks of tumor. Eighty-eight percent of the tumors positive for c-erbB-2 were NG 3 and 12% were NG 2. All c-erbB-2 tumors were aneuploid. This study demonstrates the importance of carefully assigning NGs on tissue and indicates the importance of reviewing flow cytometric data side by side with histopathologic parameters to detect discrepancies between these two modalities. Careful nuclear grading assignment can accurately predict the range of SPF.

Abstract
BACKGROUND Prognostic pathologic and clinical features for 10-year survival were determined from 22 pathologic and 5 clinical variables encountered in 1090 node-negative and 651 node-positive patients enrolled in NSABP protocol B-06. METHODS All factors were first screened univariately. Those exhibiting P values < 0.01 were entered into multivariate Cox regression models. The model with the best fit consisted of 951 negative-node and 496 node-positive patients. RESULTS Better survival in node-negative patients was noted for whites rather than blacks, for patients with favorable tumor types (tubular, mucinous, papillary) rather than intermediate (lobular invasive, classical medullary, and not otherwise specified [NOS] combinations) or unfavorable forms (NOS pure and atypical medullary), and for tumors with good rather than poor nuclear grade. Number of nodal metastases, degree of tumor elastosis, and patient age younger than 40 years of age and 65 years of age and older in addition to nuclear grade and race were found significant for node-positive patients. Relative risks for combinations of these prognostic factors were multiplicative. CONCLUSIONS The prognostic factors for node-negative patients were similar to those observed for this cohort at 8 years. Some differences noted between patients of both nodal groups in NSABP B-04 and B-06 may be related to selection requirements in the latter and hence different patient characteristics or more speculatively a change in tumor biology.

Abstract
Twenty-one pathologic and five clinical features of Stage I and II invasive breast cancers from 620 patients enrolled in National Surgical Adjuvant Breast Project Protocol B-04 were analyzed to determine their predictive value for 15-year survival. Ten pathologic features had a statistically significant univariate prognostic relationship with long-term survival. These were analyzed further using a Cox regression model that found only the number of nodal metastases (0, 1-3, 4-9, or 10+), tumor size (< or = 2.0 cm versus 2.1-4 and 4.1 + cm), and the presence or absence of nipple involvement to be significant independent prognostic discriminants. Combinations of these three characteristics modestly increased their individual prognostic value. Differences in the findings in this study from those observed in the same patient population at 5 and 10 postoperative years and their relationship to other markers detected by ancillary pathologic techniques briefly are discussed.

Abstract
Approximately 115,000 new cases of axillary node negative breast cancer were diagnosed in this country last year. Since about 20-30% of these patients will ultimately relapse and die of their disease, adjuvant systemic therapy has been advocated for this group to decrease the relapse rate and prolong survival. However, although most clinical trials have demonstrated a modest impact on disease recurrence, the available data have failed to show consistent improvements in overall survival and does not justify the generalized use of systemic treatment in this patient subgroup. For this reason, a plethora of prognostic factors have been described to identify those patients with a higher risk of recurrence to concentrate therapeutic options in this specific group. Of all the disease prognosticators studied, tumor size, nuclear grade, and proliferative indexes appear to correlate well with tumor recurrence. In addition, biologic characteristics of primary tumors such as the presence of hormone and growth factor receptors, secretion of specific polypeptides and proteases, expression of proto-oncogenes, and abnormalities in tumor suppressor genes have been shown to be potentially useful as prognostic indicators in patients with early breast cancer. Despite these provocative data, larger clinical trials are necessary before incorporating these parameters in the routine evaluation of patients with axillary node negative breast cancer.

Abstract
Standardization and quality control of quantitative microscopy techniques are distinct but related concerns. The first deals with the great variety of quantitative methods, measured features, and even response variables used in investigation of biological or clinical processes. The latter deals with reproducibility of results from those investigations across time and test performance sites. Though distinct, efforts for standardization and quality control are inherently interactive. Consensus on standard methods, instrumentation, and data analysis is hard to achieve in fields developing as rapidly as quantitative microscopy. Consensus is possible, however, on the issues that affect test performance and interpretation. For example, issues of specimen type, fixation, processing, and staining affect image cytometry just as they do flow cytometry. Raw data acquisition issues include area sampling rules and fidelity of optical and sensor systems (light wavelength, glare/stray light, lens aberrations, numerical aperture, depth of focus, scan precision, pixel spacing and depth, sensor linearity, and stability). Intermediate data issues are primarily related to image foreground/background segmentation techniques--automated versus manual, object-specific versus field-based. Data reduction and interpretation procedures also provide many roads for divergence from uniformity. Each of these issues must be considered in terms of its effect on comparability and utility of quantitative microscopy results. Quality control for quantitative microscopy is as important as standardization for its use in research programs and with clinical specimens. The sine qua non of quality control is comparison of experimental results against a known "correct" value to estimate accuracy, and against other experimental results to estimate precision.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Although many studies have found that ploidy as determined by flow cytometry correlates with grade for invasive mammary carcinomas, only a few groups of investigators have evaluated ploidy for infiltrating ductal carcinomas exclusively. In this study ploidy, as analyzed in fresh tumor specimens, was compared with grade (using the Bloom and Richardson grading scheme modified by Elston and Ellis) and each of its three components (tubule formation, nuclear pleomorphism, and mitotic rate) for 118 infiltrating ductal carcinomas. Two thirds of the neoplasms were DNA aneuploid, including 4% that were hypodiploid, 14% that were tetraploid, 8% that were hypertetraploid, and 12% that were multiploid. Ploidy correlated with nuclear pleomorphism (P = .004), mitotic rate (P = .001), and grade (P = .0007), but not with tubule formation (P = .09). Forty percent of grade I, 71% of grade II, and 83% of grade III neoplasms were DNA aneuploid. Ploidy was also compared with the results of combining nuclear pleomorphism with mitotic rate to form a five-part modified Bloom and Richardson scheme (MBRS grades I to V). The frequencies of DNA aneuploidy for tumors that were MBRS grades I, II, III, IV, and V were 25%, 65%, 66%, 73%, and 89%. This relationship was significant (P = .0006). When MBRS grades II, III, and IV neoplasms were combined and compared with MBRS grade I tumors and MBRS grade V carcinomas, the differences in frequency of DNA aneuploidy among these three groups also were significant (P = .00007). These results show that ploidy correlates with the grade of infiltrating ductal carcinoma and that nuclear pleomorphism and mitotic rate are more important than tubule formation for predicting the likelihood of DNA aneuploidy.

Abstract
BACKGROUND Amplification of the c-erbB-2 protooncogene and DNA aneuploidy have been reported to correlate with poor patient prognosis in human breast cancer. Several studies have investigated the prognostic value of these two factors in heterogeneous populations of patients with node-positive and node-negative disease. This study evaluated, on a series of patients with node-negative disease, whether c-erbB-2 proto-oncogene amplification and cellular DNA content could identify a subset of patients who, without adjuvant therapy, are destined to experience a relapse. METHODS Paraffin-embedded tissues of 78 patients were evaluated for cellular DNA content using flow cytometric analysis. Amplification of c-erbB-2 was determined on the same group of patients using slot-blot hybridization. The majority of patients were matched with control subjects for the following five clinicopathologic criteria: size of primary tumor, menopausal status, estrogen receptor, anniversary year of initial treatment, and age at treatment. Long-term follow-up (5-16 years) was available for each patient, none of whom received any form of adjuvant therapy. RESULTS The presence of an abnormal DNA stemline was found in 47% (37 of 78) of the tissue specimens, whereas only 10% (8 of 78) of the tumors expressed from 3-fold to 22-fold c-erbB-2 amplification. Combined c-erbB-2 amplification and DNA aneuploidy occurred in a small group of patients (n = 4), all of whom experienced relapse. The four remaining tumors having excessive gene copy numbers had a diploid DNA distribution. CONCLUSIONS The results indicate that tumors that overexpress the c-erbB-2 proto-oncogene have variable amounts of DNA and that c-erbB-2 amplification and DNA ploidy analysis provide limited predictive information of relapse in patients with node-negative breast cancer. Although the combination of c-erbB-2 amplification and DNA aneuploidy may be a predictor of poor prognosis in a small number of patients, neither measurement alone is effective in identifying patients at increased risk of recurrence of disease.

Abstract
Between 1977 and 1986, 75 black and 615 white women with American Joint Committee (AJC) Stages I and II breast cancer were treated with excisional biopsy, axillary dissection, and radiation therapy for breast conservation. Cyclophosphamide, methotrexate, and 5-fluorouracil, with and without prednisone and tamoxifen, was given to 92% of premenopausal, 83% of perimenopausal, and 63% of postmenopausal node-positive women; 20 of 106 (19%) postmenopausal node-positive women received tamoxifen only. The clinical characteristics of the similarly treated patients were compared. The 5-year actuarial local only first failure rate was 5% for black women and 6% for white women (P = 0.53). Regional only failure as the first site of failure was 9% for blacks versus 1% for whites (P = 0.002), with regional recurrence as any component of first failure being 16% for blacks and 4% for whites (P = 0.001). The supraclavicular fossa was identified as the primary site of regional recurrence in black patients with either pathologically positive or negative axillae. Distant metastases as the only site of first failure were significantly greater in the black population with a 20% 5-year actuarial failure rate versus 11% in white patients (P = 0.01). The 5-year actuarial overall survival for the black patients was 82% versus 91% for the white patients (P = 0.01), with no-evidence-of-disease (NED) survival being 64% and 83% (P = 0.0002) and relapse-free survival (RFS) being 61% and 77% (P = 0.01), respectively. Black patients younger than 40 years of age or with pathologically positive axillary nodes had significantly worse NED, RFS, and overall survival compared with similarly staged white patients. Cosmetic results were analyzed at 3 and 5 years after completion of therapy. Although significantly fewer black patients had an excellent-to-good cosmetic result at 3 years compared with white patients, the results were not significantly different at 5 years. These results show that appropriately selected black patients with early stage breast cancer have excellent local control after conservative surgery and radiation therapy and should continue to be offered breast preservation as an alternative to mastectomy. Patterns of failure, however, demonstrated higher regional and distant recurrence rates and lower NED, RFS, and overall survival rates in most subsets of black patients reviewed.
