Jatoi I, Kunkler IH. Omission of sentinel node biopsy for breast cancer: Historical context and future perspectives on a modern controversy. Cancer 2021; 127:4376-4383. [PMID: 34614216 DOI: 10.1002/cncr.33960] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/24/2021] [Revised: 09/09/2021] [Accepted: 09/14/2021] [Indexed: 11/10/2022]
Abstract
For older patients with clinically lymph node-negative breast cancer who have estrogen receptor-positive tumors and are treated with tamoxifen, randomized trials comparing axillary lymph node dissection (ALND) versus no ALND show that the omission of ALND improves patient quality of life and has no adverse effects on mortality. These results have served to justify sentinel node biopsy (SNB) omission in selected older patients with breast cancer. More recently, clinical trials were launched to assess SNB omission in younger patients, with recurrence and survival as the primary outcomes of interest. Three important considerations serve as the basis for these ongoing trials. First, it is assumed that SNB omission will improve patient quality of life, although, to date, there is no level I evidence to support this assumption. Second, axillary surgery has never been shown to reduce breast cancer mortality, but it does reduce the risk of axillary recurrences, although adjuvant systemic therapy and radiotherapy also reduce these recurrence risks. Finally, nodal status is losing importance as a guide for adjuvant systemic therapy decision making because these decisions are now increasingly predicated on tumor biomarkers and gene profiling, but it is gaining importance for adjuvant radiotherapy decision making. Because quality-of-life considerations are the primary motivation for abandoning SNB, there is a need for randomized trials comparing SNB versus no SNB/no axillary surgery, with quality of life as the primary end point (level I evidence). Moreover, suitable alternatives to guide adjuvant radiotherapy decision making will require validation before SNB omission can be justified for patients of all ages who have clinically node-negative breast cancer. LAY SUMMARY: In this review article, the authors provide a brief historical overview of the role of axillary surgery in breast cancer management and discuss additional studies and ramifications that should be considered before abandoning the sentinel node biopsy (SNB) procedure. Specifically, there is a need for level I evidence demonstrating that omission of the SNB procedure will improve patient quality of life and a need to validate suitable alternatives to SNB as a guide for adjuvant radiotherapy decision making.

Abstract
OBJECTIVE To determine the expressions and relationship between estrogen receptors (ERs) and progesterone receptors (PgRs) in breast cancer in Indian women. PARTICIPANTS Surgically removed breast cancer tissues were collected from Grant Medical College and Sir JJ Group of Hospitals, Mumbai, India, taking (n = 300) cases of infiltrating duct cancer of Indian women after radical mastectomy and lumpectomy; the age- and menopausal-related subgroups satisfied this requirement. MEASUREMENTS Statistical significance was calculated by the likelihood ratio test; relative risk served to check for significant differences. Relapse-free interval probabilities were calculated according to Kaplan and Meier, with Cox-Mantel test comparing survival functions and P values. RESULTS We observed that only in middle-aged postmenopausal patients bearing pT2 tumors were ER and PgR receptors shown to have a prognostic significance with the lowest tested cutoff value being 5 fmol/mg. CONCLUSION Immunohistochemistry analysis has been shown to be a prognostic factor for patients with breast cancer; the major aim of determining the ER receptor status is to assess predictive response to hormonal therapy.

Abstract
PURPOSE The Nottingham Prognostic Index (NPI) is used to predict survival in patients with breast cancer. This index is based on tumor size, lymph node stage, and histological grade and allows the stratification of patients into three different prognostic groups. Our aim was to verify the effect of some prognostic variables on survival and to establish the independent influence of each of these variables by a survival regression analysis. We applied the NPI to the same group of patients to assess its predictive power and reproducibility. METHODS We evaluated 311 women with breast cancer treated between January 1993 and December 1998. RESULTS In a multivariate analysis (Cox proportional hazard model), only size, lymph node involvement, and histological grade were independent prognostic factors. The survival curves obtained after applying the NPI were similar to those for the factors with independent prognostic significance derived from our multivariate analysis. CONCLUSION The NPI allows us to accurately predict prognosis, and we advocate its standardized use.

Abstract
A wide range of frequencies has been reported for blood vessel invasion (BVI) among patients with breast cancer, however, the prognostic significance of BVI remains controversial. Three hundred ninety-eight Japanese patients with breast cancer, operated on during the period between 1971 and 1987, were studied. We investigated five factors, including BVI, lymph-node status (n), clinical tumor size (T), histological grade (HG), and tumor necrosis (TN), followed for a median of 10 years. BVI was detected by hematoxylin and eosin (HE) staining and both factor VIII-related antigen and elastica van Gieson staining. BVI detected by HE staining alone was defined as BVIh. The subtypes of BVI were classified as follows: BVI e, BVI detected only by elastica van Gieson staining; BVI f, BVI detected only by factor VIII-related antigen staining; and BVI e/f, BVI detected by both factor VIII-related antigen and elastica van Gieson staining. BVI-positive tumors were defined as lesions showing BVI e, BVI f, or BVI e/f. BVI and BVIh were presented in 27.4%, 6.5% of all cases, respectively. The mean diameters of the calibers of BVI e, BVI f, and BVI e/f were 141.9+/-80.5 microm, 61.0+/-37.4 microm, 136.0+/-102.0 microm, respectively (P<0.0001). Seventy-three patients (18.3%) had recurrence and 60 patients (15.1%) died of breast cancer. Univariate analysis showed that BVIh (P <0.0001), BVI (P<0.0001), n, T, and HG were significantly predictive of 20-year RFS and OS. Multivariate analysis showed that BVI (P<0.0001, P = 0.0088, respectively), n, T, and HG were all significant and independent prognostic factors for RFS and OS. On the other hand, BVIh was an independent factor for RFS (P = 0.0475), but of borderline significance for OS (P = 0.0506). When stratified by BVI, BVI e, and BVI e/f were significantly predictive of 20-year RFS or OS (P < 0.0001). We can confirm BVI, especially BVI e and BVI e/f, are significant independent prognostic factors associated with long-term survival in Japanese breast cancer patients.

Abstract
The Nottingham Prognostic Index (NPI) is an index, derived from a retrospective multivariate study, that is able to predict survival in patients with breast cancer. The index is based on tumour size, lymph node stage and histological grade and allows the stratification of patients into three different prognostic groups. The aim of this study was to verify, according to our experience with a long-term follow-up, the effect of some prognostic variables on survival and to establish the independent influence of each of them by means of a survival regression analysis. Then we applied the NPI to the same group of patients in order to assess the predictive power and reproducibility of the index. 402 patients treated from January 1979 to December 1987 were evaluated. In multivariate analysis (Cox proportional hazard model), only size, lymph node involvement and histological grade remained independent prognostic factors. The survival curves obtained after applying the NPI are similar to those for the factors with independent prognostic significance derived from our multivariate analysis. Our improved survival rates may be attributed to the administration of adjuvant therapies to a larger number of patients. The NPI allow us to accurately predict prognosis and we advocate its more common use.

Abstract
This study was undertaken to determine the value of angiogenesis and blood vessel invasion (BVI) using both Factor VIII-related antigen and elastica van Gieson staining in predicting 20-year relapse-free survival (RFS) and 20-year overall survival (OS) rates in Japanese patients with node-negative breast cancer. Two hundred and sixty patients were studied. We investigated nine factors, including angiogenesis (average microvessel count (AMC)), BVI, proliferating cell nuclear antigen (PCNA), p53, c-erbB-2, clinical tumor size (T), histological grade, tumor necrosis, and lymphatic vessel invasion (LVI). Twenty-five patients (9.6%) had recurrence and 17 patients (6.5%) died of breast cancer. Univariate analysis showed that BVI, AMC, T, histological grade, PCNA, p53, and tumor necrosis were significantly predictive of RFS or OS. Multivariate analysis showed that AMC, BVI, and T were significant independent factors for RFS or OS. Moreover, the combination of AMC/BVI was an especially significant factor for RFS or OS (P < 0.0001, P = 0.0003, respectively). When stratified by T, a significant impact of AMC or BVI on RFS was seen in patients with T1, T2, and T3 carcinomas. Multivariate analysis in patients with T2 carcinoma showed that both AMC and BVI were significant independent factors for RFS (P = 0.0231, P = 0.0388, respectively) and OS (P = 0.0331 and P = 0.0479, respectively). AMC, BVI, and T were independent prognostic indicators. As the combined impact of AMC/BVI is especially strong, AMC/BVI is useful in selecting high-risk node-negative breast cancer patients who may be eligible to receive aggressive adjuvant chemotherapy.

Abstract
This study was undertaken to determine the absolute and relative value of blood vessel invasion (BVI) using both factor VIII-related antigen and elastica van Gieson staining, proliferating cell nuclear antigen (PCNA), p53, c-erbB-2, and conventional prognostic factors in predicting relapse-free survival (RFS) and overall survival (OS) rates associated with long-term survival in Japanese patients with node-negative breast cancer. Two hundred patients with histological node-negative breast cancer were studied. We investigated nine clinicopathological factors, including PCNA, p53, c-erbB-2 using permanent-section immunohistochemistry, clinical tumour size (T), histological grade (HG), mitotic index (MI), tumour necrosis (TN), lymphatic vessel invasion (LVI) and BVI, followed for a median of 10 years (range 1-20). Twenty-one patients (10.5%) had recurrence and 15 patients (7.5%) died of breast cancer. Univariate analysis showed that BVI, PCNA, T, HG, MI, p53, c-erbB-2 and LVI were significantly predictive of 20-year RFS or OS. Multivariate analysis showed that BVI (P = 0.0159, P = 0.0368), proliferating cell nuclear antigen (PCNA) (P = 0.0165, P = 0.0001), and T (P = 0.0190, P = 0.0399) were significantly independent prognostic factors for RFS or OS respectively. BVI, PCNA and T were independent prognostic indicators for RFS or OS in Japanese patients with node-negative breast cancer and are useful in selecting high-risk patients who may be eligible to receive strong adjuvant therapies.

Abstract
BACKGROUND: This study was undertaken to determine the absolute and relative value of angiogenesis, proliferating cell nuclear antigen (PCNA) and conventional prognostic factors in predicting relapse-free survival (RFS) and overall survival (OS) rates associated with long-term survival in Japanese patients with node-negative breast cancer. PATIENTS AND METHODS: Two hundred patients with histological node-negative breast cancer were studied. We investigated nine clinicopathological factors, including angiogenesis, PCNA using per-manent-section immunohistochemistry, clinicaltumor size, histological grade (HG), tumor necrosis, lymphatic vessel invasion (LVI), histological extension, histological classification, and infiltrating growth (INF), followed for a median of 10 years (range, 1 to 20). RESULTS: Twenty-one patients (10.5%) had recurrence and 15 patients (7.5%) died of breast cancer. Univariate analysis showed that PCNA, clinical tumor size, HG, angiogenesis, and LVI were significantly predictive of 20-year RFS or OS. Tumor necrosis was significantly predictive of OS, not of RFS. Multi-variate analysis showed that clinical tumor size (P = 0.0003), angiogenesis (P = 0.0003), PCNA (P = 0.0064), and HG (P = 0.0401) were significant independent prognostic factors for RFS. PCNA (P< 0.0001) and clinical tumor size (P = 0.0112) were significant independent prognostic factors for OS, while angiogenesis was a borderline significant factor. CONCLUSION: PCNA and angiogenesis were important new prognostic factors in node-negative breast cancer patients.

Abstract
Tumor samples of 240 patients with primary breast cancer were biochemically and immunohistochemically investigated for estrogen receptors (ER) and, in 130 of the samples, for progesterone-receptors (PgR) in order to examine reasons for discordant findings. The biochemical (DCCA) and immunohistochemical assays (ICA) yielded positivity in 71% for ER, and in 44% for PgR. Concordant ER-DCCA and ER-ICA results were obtained in 84%; two thirds of the discordant ER-findings manifested as DCCA-neg/ICA-pos. Concordance in the case of PgR amounted to 72%, and of the discordances 60% were DCCA-neg/ICA-pos. Significant association with postmenopausal status existed only for ER positivity in ICA (p = 0.01), whereas ER-DCCA, PgR-DCCA and PgR-ICA were all more or less independent of the menopausal status. The frequency of discordances was independent of menopausal status. Discordance for ER-assays increased significantly near the respective cut-off point; this was not unequivocally true for PgR-assays. The correlation of tumor types of sparse cellularity, as well as prominent stroma content ('scirrhous carcinoma') with increased frequency of the constellation DCCA-neg/ICA-pos was of borderline significance for PgR (p = 0.06), but not for ER. The percentage of discordant ER-findings, figuring as DCCA-neg/ICA-pos, was statistically significantly increased in locally advanced breast cancer (p = 0.03). Fibrocystic disease in peritumoral breast tissue had no impact on receptor-assay discordance. In any case, the models derived from theoretical thought, laboratory data and singular observations can only in part explain the discordance in steroid receptor values measured with different methods.

Abstract
This study was conducted to determine the prognostic influence of obvious peritumoral vascular emboli as prospectively determined by a simple routine slide examination in patients with operable node-negative breast cancer. Obvious peritumoral emboli (OPE) were defined by the presence of neoplastic emboli within unequivocal vascular lumina (including both lymphatic spaces and blood capillaries) in areas adjacent to but outside the margins of the carcinoma. OPE were assessed routinely on 5 microns thick haematoxylin and eosin-stained sections for each of 1320 primary operable node-negative breast cancers from 1975 to 1992 at our institution. OPE and other prognostic variables (tumour size, SBR grade, oestrogen and progesterone receptor status) were correlated to overall survival (OS) and metastasis-free interval (MFI) by means of univariate and multivariate analysis with a median follow-up of 103 months. OPE were found in 19.5% of tumours. In univariate analysis, OPE were related to tumour size (P = 6.3 x 10(-5)) and histologic grade (P = 4.9 x 10(-7)). Statistically significant correlations were found with OS (P = 4.6 x 10(-5)) and MFI (P = 6.4 x 10(-9)). Furthermore, in multivariate analysis, OPE was an independent prognostic variable, the most predictive factor for MFI (P = 7.7 x 10(-7)) before tumour size and grade, and was second after tumour grade for OS (P = 0.002). This study on a large unicentric series and with a long follow-up confirms the prognostic significance of vascular emboli in patients with operable node-negative breast carcinoma. Importantly, vascular emboli were found to be accurately detectable by a simple routine and non-time-consuming method. Therefore, such obvious vascular emboli should be considered as an important cost-effective, prognostic variable in patients with node-negative breast carcinoma.

Abstract
This study was undertaken to assess blood vessel invasion (BVI) and other histologic features to determine the best method of histologic prognosis in node-negative breast cancer patients. The prognostic significance of the clinico-pathological findings was evaluated in 70 patients with node-negative breast cancer among 135 patients operated on between 1971 and 1981. The prognostic factors investigated included BVI, peritumor lymphatic invasion, clinical tumor size, nuclear grade, histological grade, mitotic grade, and tumor necrosis. BVI was detected by factor VIII-related antigen and elastica van Gieson staining. BVI-negative patients had a 20-year cumulative survival of 93.7%, versus 74.7% for BVI-positive patients (P = 0.0294). The clinical tumor size also correlated well with prognosis (P < 0.001). However, the other histologic features did not correlate with a poor prognosis. Moreover, we retrospectively examined the effect of postoperative chemotherapy for patients with BVI and T3, and the prognosis of those given chemotherapy seemed to be better than that of those who were not. Tumors measuring more than 51 mm and BVI may thus represent adverse prognostic factors in node-negative breast cancer patients.

Abstract
BACKGROUND The frequency of small (< or = 1 cm) axillary lymph node negative invasive breast cancers (T1a,b N0 M0) is increasing because of wider implementation of breast cancer screening. Identification of prognostic factors for these patients has been based largely on retrospective pathology review. The authors analyzed histologic factors recorded in the original pathology reports to determine predictors of recurrence for patients with T1a,b N0 M0 breast cancer. METHODS Two hundred eighteen patients were studied. Potential prognostic factors including measured millimeter tumor size in three dimensions, histologic grade, nuclear grade, and presence or absence of lymphatic vessel invasion were documented prospectively in routine surgical pathology reports of a large community (nonuniversity based) hospital. Follow-up was performed annually by the tumor registry. RESULTS With a median follow-up of 6.9 years (range, 3-15.8 years), overall recurrence free survival was 93%. Poor nuclear grade (hazard ratio, 5.8; 95% confidence interval, 1.70-19.82; P = 0.004) and lymphatic vessel invasion (hazard ratio, 4.6; 95% confidence interval, 1.34-15.61; P = 0.01) were independent predictors of recurrence. Only 10% of patients had cancers with both poor nuclear grade and lymphatic vessel invasion and their 67% 7-year recurrence free survival (RFS) rate was significantly lower than the 92% RFS rate observed for patients with one of these two factors (P = 0.007) and the 99% RFS for patients with neither poor risk factor (P = 0.0001). CONCLUSIONS The combination of poor nuclear grade and lymphatic vessel invasion identifies a very small subset (10%) of patients with T1a,b N0 M0 breast cancer with a significant relapse risk that warrants consideration of adjuvant systemic therapy. However, the majority of patients with T1a,b N0 M0 breast cancer have an exceptionally good prognosis.

Abstract
The immunohistochemically determined receptor status, as well as first-generation risk factors (tumor size, lymph node status, histologic grading including subfactors, tumor histology, and biochemically determined receptor status) were prospectively analyzed in 288 cases of primary breast cancer for their impact on recurrence-free survival (RFS) and overall survival (OS) after a median observation period of 41 months. Immunohistochemically (ER-ICA) and biochemically determined estrogen receptors (ER-DCC), as well as tumor size, lymph node status, histologic grading, mitotic rate, and nuclear polymorphism, were of prognostic value for recurrence-free survival and/or overall survival. In multivariate analysis, lymph node status, tumor size, and mitotic rate proved to be independent prognosticators; ER-ICA showed significance in the univariate analysis which dropped, however, when multivariate analysis was applied. The prognostic power of histologic grading in our series seemed to depend mainly on the subfactors which relate to nuclear features.

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
Five hundred six consecutive cases of ductal infiltrating carcinoma of the breast (T1-T2,N0,M0) were evaluated to define the frequency of peritumoral lymphatic invasion (PLI) and verify its possible prognostic significance. Histologically, PLI was characterized by the presence of neoplastic emboli within vascular lumina lined by recognizable endothelial cells, adjacent to but outside the margins of the carcinoma. In routine histopathologic assessment the frequency of PLI was 68% whereas in a randomly selected group of 234 reviewed cases the frequency rose to 20%. Patients with routinely evaluated PLI had a worse prognosis than those without PLI with reference both to disease-free survival (P = 0.0001) and total survival rates (P = 0.0001). The difference for local recurrences was prognostically highly significant (P = 0.0001) and also significant for the development of metastases (P = 0.0576). In the reviewed material the difference in prognosis between PLI-positive and PLI-negative cases was not confirmed for total survival whereas the significance for the disease-free interval persisted. The assessment of PLI, carried out following strict histopathologic criteria, appears to select a group of node-negative breast cancer patients who have an increased risk of recurrences and might benefit from a treatment different from that reserved for node-negative and PLI-negative patients.

Abstract
In 164 breast carcinomas the presence of peritumoral lymphatic vessel invasion (PLVI) was evaluated and correlated with other known indicators of prognosis and with the clinical outcome of the patients. Overall 22% of tumors were PLVI-positive. The presence of PLVI was significantly associated with axillary node involvement (p less than 0.0001) and tumor size (p = 0.005), and tended toward an association with grading (p = 0.065). No significant association was found between PLVI and steroid hormone receptors, DNA ploidy, or proliferative activity. Univariate analysis shows that peritumoral vessel invasion was significantly associated with a higher risk of recurrence (p = 0.012) and with a trend toward shorter survival (p = 0.074). Besides the presence of PLVI, prognosis was significantly worse also for patients with high proliferative aneuploid tumors and with axillary node metastases. Moreover, within the subsets of patients generally considered to have good prognosis, the presence of PLVI identified patients with a trend for higher risk such as those with PLVI-positive diploid tumors, PLVI-positive low-proliferative tumors, and PLVI-positive node-negative tumors. Adopting multivariate analysis, PLVI failed to retain prognostic importance when adjusted for node status, DNA ploidy, and proliferative activity. In conclusion, we found that the presence of PLVI has prognostic significance when singly evaluated. Multivariate analysis shows that PLVI is not an independent prognostic factor in stage I-II breast cancer.

Abstract
In a previous study of a series of 105 patients with primary breast cancer we found that the progesterone receptor (PgR) status was an important prognostic factor for early recurrences. 95 patients from the same series were followed-up for a median of 9.5 years and reassessed for the prognostic value of PgR status by univariate and multivariate statistical methods. In univariate analysis, the disease-free interval was only related to the lymph-node status. For overall survival, PgR and combined PgR-ER (oestradiol receptor) status had a prognostic value (P = 0.035 and 0.05, respectively). Moreover, PgR status was found to be discriminant for the survival of the node-negative patients (P = 0.017). In multivariate analysis, ER and PgR status were not significant, indicating that receptor status is not a powerful predictor of the course of breast cancer.

Abstract
Pathologic features of 378 breast carcinomas without axillary lymph node metastases were correlated with long-term prognosis. Mitotic count, the feature best predicting prognosis, was most useful at lower mitotic count levels than usually studied. Cases with less than 4.5 mitotic figures per ten high-power fields had a 20-year tumor-related survival of 73% versus 48% for those with higher mitotic counts. Low and high mitotic count groups had significantly different prognoses for T1c, T2, and T3 tumors. Multivariate analysis showed that the best combination of features predicting tumor-related death were high mitotic count (relative risk, x 2.8), large tumor size (relative risk, x 1.7), lymphatic invasion (relative risk, x 1.7), and skin or subjacent muscle or chest wall invasion (relative risk, x 2.5). Nuclear grade, Bloom-Richardson grade, modified Scarff-Bloom-Richardson grade, Fisher's grade, and necrosis correlated well with survival but had no significant additional predictive value when adjusted for the mitotic count.

Abstract
The purpose of this study was to characterize breast carcinomas by cell kinetic parameters. Mitotic rate (MR) and flow cytometrically (FCM) measured cell cycle distribution as well as chromatin testing in situ employing heparin for determination of activated chromatin, provided the following results: MR counted in 73 unselected carcinomas showed an increase up to a tumor size of 4.2 cm (p less than 0.05); beyond this diameter, the MR was found to decrease. In T1-T2 carcinomas, cell cycle stage analysis yielded higher percentages of cells in S and G2M phase for ductal (13% and 12%, N = 22) than for lobular (8% and 7%, N = 8) node-negative carcinomas (p less than 0.002). In ductal carcinomas, lymph node involvement was reflected by higher % G2M values (15%, N = 26) compared with negative cases (12%, N = 22) (p less than 0.05). Ductal node-positive T3-T4 carcinomas (N = 10) revealed a higher % S value (16%) than their T1-T2 counterparts. A correlation between MR and % G2M was established only up to a tumor size of 4.2 cm (r = 0.39, p less than 0.05). A highly sensitive ('H') and a poorly sensitive ('P') subgroup of carcinomas with respect to heparin-induced changes in fluorescence intensity of the G1/0 peak of the DNA aneuploid cell line were identified, as previously shown. These subgroups were here updated with a larger number of carcinomas and were limited to T1-T2 cancers (N = 57). Group 'H' included more younger patients (p less than 0.005), less cases with nodal involvement in ductal carcinomas (p less than 0.05), and lower % G2M values in lobular node-negative cases (p less than 0.05), than group 'P'. DNA diploid cells always existing in DNA aneuploid carcinomas are more sensitive than their aneuploid counterparts (p less than 0.01); however, they strengthen the stratification to 'H' and 'P'. We suggest 'H' carcinomas to be less aggressive than 'P' carcinomas. Small breast carcinomas are recommended to cell kinetic investigations for individualizing adjuvant therapy.

Abstract
Between October 1977 and December 1983, 379 consecutive patients have been treated for unilateral, non-metastatic breast cancer, either with conservative (n = 205) or radical surgery (n = 174), with axillary dissection in all the cases. None of them had histologically proved lymph node involvement. Oestrogen receptor (ER) and progesterone receptor (PR) levels were measured on each tumour. Levels greater than 5 fmol mg-1 cytosolic protein were considered as positive for both ER and PR. At 5 years, overall survival (OS) and disease-free survival (DFS) are respectively 88% and 78%. Unifactorial analysis using Kaplan and Meier estimates and the log rank test revealed that OS was significantly related to age (P less than 0.05), tumour size (P less than 0.001), histological grading (SBR) (P less than 0.01), ER (P less than 0.001) and PR (P less than 0.001). DFS was significantly related to the same factors. Menopausal status, number of breast tumour foci and previous familial history of breast cancer were not significant. Multifactorial analysis revealed that DFS was significantly related to age (bad prognosis (b.p.) less than or equal to 37 years old), tumour size and histological grading (b.p. SBR = 3), and that OS was significantly related to tumour size and PR (b.p. PR less than or equal to 5 fmol mg-1 protein). A prognostic score has been constructed for both DFS and OS. These scores divide our patients into three significantly different (P less than 0.0001) groups with good, intermediate and bad prognosis.

Abstract
Axillary nodal status was analysed in 960 consecutive cases of primary invasive breast cancer operated in two Danish hospitals. After stratification according to the number of nodes removed, the rate of node positivity in each subgroup was calculated. We found that the probability of finding at least one metastatic node increased continuously up to about 10 removed nodes. In lymph node negative patients, who did not receive any adjuvant treatment, there was a significant association between the recurrence-free survival and the number of nodes removed, provided that less than 8-10 nodes had been collected. The percentage of node positivity in each subgroup seemed to level off above 10 nodes at about 64%, suggesting that this represents the true rate of node positivity at the time of primary surgery. We conclude that about 10 axillary nodes should be removed in order to minimize the risk of erroneous classification of the axilla.

Abstract
We studied cellular proliferation by measuring the tritiated thymidine labeling index (TLI) in slices of primary invasive breast carcinomas. Estrogen receptor (ER) and progesterone receptor (PgR) were measured by ligand-binding assay. The TLI was a strong independent predictor of survival and relapse-free survival in women with or without axillary lymph nodal metastases and in American Joint Committee stage I. In operable node-negative women treated surgically, predicted survival at 5 years was 89 +/- 4% (probability +/- standard error) for 81 patients with low TLI (less than or equal to 3%), 64 +/- 7% for 101 with mid TLI (3.1-8%), and 66 +/- 6% for 86 with high TLI (greater than 8%) (P = 0.001). Probabilities of survival for patients with positive axillary nodes were 79 +/- 6% for 86 with low, 71 +/- 7% for 71 with mid, and 52 +/- 6% for 89 with high TLI (P = 0.0002). In stage I patients (tumor diameter not exceeding 2 cm), 5-year survival probabilities were 93 +/- 4% in 70 with low, 72 +/- 8% in 43 with mid, and 58 +/- 10% in 35 with high TLI, (P = 0.0005). The TLI was predictive for survival and relapse-free survival within subgroups positive and negative for ER and positive for PgR (P less than 0.05) in stage I patients, and a predictive trend was observed in the PgR-negative subgroup (P = 0.16). TLI also predicted within different categories of vascular invasion and nuclear grade. A stepwise Cox proportional hazards model selected TLI, number of positive axillary lymph nodes, and maximum diameter of the breast carcinoma as independent variables predictive of relapse, and added ER as a fourth variable for prediction of survival.

Abstract
The authors report on 767 consecutive primary Stage I-II breast cancer cases followed-up from 3 to 8 years. The estrogen receptor (ER) content was determined in all cases and did not influence the treatment choice. A correlation was attempted between ER and menstrual or pathological nodal status (N) or the 5-year disease-free survival (DFS). ER was correlated with menopausal status ER+ cases being more frequent in postmenopausal patients, whereas no correlation was observed between ER and nodal status. In absence of nodal involvement (N-) the prognosis was not influenced by the ER status. A significantly better DFS was evident for ER+ respect to ER- patients in the N+ series but such a correlation is questionable as the adjuvant treatment (hormone or chemotherapy) given to such patients may have influenced the DFS according to the ER status. According to the present study, ER determination should not be used as a discriminant in the performance of adjuvant postoperative treatment based on a prognostic judgment.

Abstract
Metastatic bone disease was evaluated in 380 consecutive patients at the time of first metastasis of breast cancer. Studies included radiographic examination, radionuclide examination, and bone marrow biopsy. Radiographs of the skeleton demonstrated metastases in 120 patients (32%), and in 40 of these patients (13%) the bone was the only site of metastases. The diagnostic efficiency was 82% for bone scanning, 80% for pain evaluation, 59% for s-calcium analyses, and 77% for s-alkaline phosphatase analyses. Bone scanning is an effective method to exclude metastatic bone disease (sensitivity: 96%). A positive scan, however, requires radiologic confirmation (specificity: 66%). Bone scanning of the skeleton should be the initial staging procedure in all patients with recurrent breast cancer with no clinical or biochemical signs of bone metastases. Bilateral posterior iliac crest bone marrow aspirations and bone biopsies were positive in 82 out of the 320 patients who underwent biopsy. The frequency of positive bone marrow biopsy was significantly correlated with both the site of radiographic metastases and with the total number of involved bone regions. Routine bone marrow biopsies are indicated in patients with a positive bone scan, but a negative x-ray examination. In these cases biopsies should be performed bilaterally.

Abstract
The DNA labelling index (LI), representing the fraction of S-phase cells, was studied in 76 patients operated on for breast cancer from 1975 to 1979. No patient had lymph node involvement following axillary dissection (N-), and no adjuvant medical treatment was given. Patients were classified in one of two groups according to the median LI. Patient distribution by age, tumour size, and receptor status was identical in both groups. A higher frequency of grade 3 tumours was noted in the group with an LI above the median value. The cell proliferation rate was an important discriminative factor for metastatic potential. The probability of survival at 8 years for patients with a high LI was significantly lower than that of patients with low LI (36% versus 100%; p less than 0.001). Relapse-free survival at 8 years was respectively 56% and 83% (p less than 0.02). At 2 years, these values were 75% and 100%, indicating the early occurrence of metastases. By contrast, the LI had no prognostic value concerning loco-regional disease recurrence or survival after the appearance of metastasis. No relationship was found in this study between survival and other prognostic factors, namely tumour size, histological grade, or hormone receptor level. The LI currently appears to be the best prognostic factor for N- breast cancer. High risk patients identified by this method could thus be offered adjuvant medical treatment.

Abstract
Recent studies have presented compelling evidence to support the prognostic importance of peritumoral lymphatic and blood vessel invasion in breast cancer. This parameter appears to be particularly valuable in the hands of pathologists who are experienced in diseases of the breast and who have developed standardized criteria and expertise in their recognition. However, its application is seriously hampered by various factors, especially interobserver and intraobserver differences in interpretation. A more uniform and objective approach, such as the use of immunohistochemical techniques, may be helpful in overcoming these obstacles. This may render lymphatic and blood vessel invasion a reliably reproducible indicator that a practicing pathologist can utilize to recognize high-risk patients and recommend appropriate therapy. The extension of this approach to evaluate neoplasms of other organs--such as malignant melanomas and thyroid, uterine, and cervical carcinomas--should also be explored.

Abstract
Cox's proportional hazards regression model was used to analyze the prognostic significance of multiple variables affecting recurrence and survival in patients with Stage II breast cancer. Among the variables were biochemical estrogen (ER) and progesterone receptor (PgR) values and results of a histochemical estrogen-binding assay using a fluoresceinated bovine serum albumin-estradiol conjugate where carrier and label were bound at position 17. In 190 cases ER and PgR were not found to be significantly associated with either disease recurrence or patient survival. On the other hand, patients with tumors that were demonstrably "rich" in estradiol ligand conjugate binding by histochemistry experienced both a longer disease-free interval (P less than 0.03) and survival (P less than 0.02) than did patients whose tumors were "poor" in conjugate binding or showed a heterogeneous population of positively and negatively stained cells. A patient with a tumor rich in estrogen binding was five times more likely to survive than a patient with a neoplasm that was poor in estrogen binding by histochemistry. These results indicate that the histochemical technique used provides new and independent parameters for determination of prognosis in Stage II breast cancer.

Abstract
Tissue carcinoembryonic antigen (CEA) and cytosolic estrogen and progesterone receptors were studied in 15 patients with cystosarcoma phyllodes (CSP) aiming at predicting recurrence of the tumor. Polyclonal (rabbit, monospecific) and monoclonal (mouse) antibodies anti-CEA were applied to formalin-fixed, paraffin-embedded tissue sections using an indirect (PAP) immunoperoxidase method. Estrogen receptors (ER) and progesterone (PR) receptors were determined by a charcoal-dextran method. ER was detected in 4 of 15 primary CSP (mean level, 22 fmol/mg protein). CEA was demonstrated exclusively in the epithelial components of 12 of 15 tumors. Strong expression of CEA was verified in eight tumors, six of which recurred locally one or more times. None of the seven tumors negative or weakly reactive for CEA had recurrences. No correlation was found between expression of tissue CEA and steroid receptor status of the tumors. Our data indicate that strong CEA expression in CSP correlates with tumor recurrence.

Abstract
Flow cytometric DNA analysis was performed on 168 consecutive primary operable breast cancers and the results correlated with thymidine labeling, estrogen receptor (ER) and progesterone receptor values, and various histologic parameters. Seventy-five cancers (45.0%) were diploid and 93 (55.0%) aneuploid. In 83.9% of aneuploid cancers, the DNA index fell between 1.1 and 2.0. Thirteen cancers were hypertetraploid and three hypodiploid. The percent of S-phase cancers (SpF) varied from 1.1% to 24.4%, with a mean of 8.0% and a median of 7.1%. The mean SpF of diploid cancers was 5.2%; of aneuploid cancers, 10.3%. There was no significant correlation between SpF or ploidy and tumor size or axillary lymph node status. The thymidine labeling index (TLI) varied from 0.2 to 23.1, with a mean of 7.5 and a median of 6.1. There was good correlation between TLI and SpF (r = 0.892, P = 0.0001). ER-negative tumors had a significantly higher mean SpF (10.3%) than did ER-positive tumors (6.7%), but there was no significant correlation between ploidy and receptor positivity or negativity. There was a good correlation between invasive tumor necrosis, poor cytologic differentiation, aneuploidy, and above-median SpF. Only a fair correlation was observed between mitotic rate and SpF. A classification of invasive breast cancers based on ploidy and SpF is proposed.

Abstract
The value of estrogen receptor (ER) measurements for predicting recurrence and survival rates in primary breast cancer was examined in 121 women who were followed from 5 to 12 years after mastectomy with a median follow-up of 64 months. The prognostic significance of the ER status was evaluated independently and in association with tumor stage, axillary node metastasis, and histopathologic grade. The independent evaluation demonstrated no statistically significant difference in prognosis between women with ER-negative and ER-positive cancers, although the latter group tended to have a longer time to recurrence and longer survival. Multivariate analysis of the data by Cox's proportional hazard regression techniques revealed a synergistic effect of ER status on the risk associated with axillary node metastasis. Patients with nodal metastasis were at 2.8 times the risk of recurrence compared to patients without metastasis. For women with nodal metastasis whose primary cancer was ER-negative, this risk increased to 4.6 times compared to women without metastasis and ER-positive tumors (P = 0.0003). The risk of cancer-related death was 5.6 times more likely for poorly differentiated tumors than for highly differentiated tumors. Patients with poorly differentiated ER-negative tumors were at an even higher risk (7.0) of dying than women with highly differentiated ER-positive carcinomas (P = 0.009). In conjunction with tumor stage, axillary node metastasis and histopathologic grade ER determination is useful for identifying subpopulations at increased risk of tumor recurrence or mortality.

Abstract
The S-phase fraction (SP) measured by flow cytometry of DNA and the thymidine labeling index (TLI) measured autoradiographically indicate the proportion of carcinoma cells currently synthesizing DNA and reflect the rate of proliferation. The TLI and SPF are lognormally distributed. The median TLI performed to maximize precursor uptake is near 5% (5 labeled carcinoma cells per 100) the mean near 7%, and the range from less than 1% to near 40%. Corresponding values for the SPF measured by DNA flow cytometry are slightly higher when appropriate measures are taken to reduce background debris counts and other artefacts. Residual elevation of SPF above TLI may result from S-phase arrested cells. Flow cytometric histograms show that clearly aneuploid cell lines exist in 50-80% of primary breast carcinomas. Aneuploid breast carcinomas have higher mean TLI than diploid breast carcinomas, and therefore proliferate more rapidly. They also more frequently lack estrogen receptor (ER). Carcinomas with minimal nuclear anaplasia, particularly those of tubular, mucinous, infiltrating lobular and adenocystic types have low TLI and SPF, whereas carcinomas with highly anaplastic nuclei, including medullary carcinomas, have high TLI and SPF. TLI and SPF correlate inversely with ER and PgR content, have no relationship to axillary lymph nodal status, and have a weak positive correlation with tumor size and a weak negative correlation with age. High TLI predicts a high risk of early relapse after primary therapy for both node-negative and node-positive carcinomas. Carcinomas that produce brain metastases have particularly high TLI. Current evidence suggests that high SPF and aneuploidy may prove to have prognostic significance like TLI.

Abstract
As known from previous reports, the DNA synthesis fraction of mammary carcinoma cells is correlated with the course of the disease and response to adjuvant therapy. Quantitative parameters of the proliferative activity can be determined by the classic 3HTdR-labelling technique as well as by the more rapid flow cytometric (FCM) DNA analysis. The values of DNA-cytometric S-phase fractions in breast cancers reported up to now were consistently higher than those obtained by the 3HTdR labelling index (LI). This discrepancy was surmounted in the present study by corrections for systemic errors of the method. The fractions of cells in stages of the cell cycle as well as the DNA indices (DI) in 155 cases of primary resectable breast cancers were analyzed by DNA flow cytometry. The patients were aged between 24 and 88 years. As indicated by a bimodal age distribution with a decrease at age 60, the patient population was a representative of the generally known breast cancer incidence. 54% of the patients had aneuploid tumor cells with preferences of DNA indices 1.6 and 2.0. In the remaining 46%, no cell populations with deviating DNA content could be detected, in part possibly due to very small differences beyond the limits of detection. No correlations were found between age, menopausal status, histologic type of tumors, tumor size, fractions in stages of the cell cycle and proliferative index (PI = S + G2 + M in %), except a significant correlation between the S-phase fractions and the (G2 + M)-phase fractions in a ratio of approximately 1.(ABSTRACT TRUNCATED AT 250 WORDS)
