Abstract
Better mechanisms of predicting prognoses in patients with metastatic breast cancer will improve the identification of patients for whom curative treatments may be the most effective. In this study, the prognostic value of 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) was assessed in patients with metastatic breast cancer. A retrospective analysis of women who underwent 18F-FDG PET/CT for staging of newly diagnosed metastatic breast cancer was conducted. In each patient, the maximum standardized uptake value (SUV) and total lesion glycolysis (TLG) of primary tumors and regional lymph nodes were measured and analyzed for association with survival using the Cox proportional hazards regression model. From 346 consecutive patients, 32 with metastatic invasive ductal carcinoma of the breast were included in the study. The median duration of follow-up was 22.5 months. Disease progression occurred in 26 patients, and 11 patients died. When multivariate analyses with a stepwise forward regression were applied, only the maximum SUV and TLG of regional lymph nodes showed a significant correlation with progression-free survival and overall survival, respectively. This study demonstrates that increased 18F-FDG uptake in regional lymph nodes is a strong independent predictor of survival in women with metastatic invasive ductal carcinoma of the breast.

Guo S, Shi Y, Lu S, He Y, Jin G, Zhang S, Li X. The taxane-based chemotherapy triplet is superior to the doublet in one to nine node-positive but not node-negative triple-negative breast cancer: results from a retrospective analysis. J Cancer 2020; 11:6653-6662. [PMID: 33046986 PMCID: PMC7545687 DOI: 10.7150/jca.44768] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2020] [Accepted: 09/08/2020] [Indexed: 12/31/2022] Open
Abstract
Background: Taxane-based regimens that are frequently used in adjuvant chemotherapy in early triple-negative breast cancer (TNBC) include a three-drug regimen (TAC and AC-T) and a two-drug regimen (TA and TC). Whether pathological lymph node stage guides taxane-based de-escalating chemotherapies in TNBC in adjuvant setting is still unclear. Methods: We retrospectively examined 381 patients with early TNBC over a median follow-up period of 75.9 months and compared the disease-free survival (DFS) and overall survival (OS) of patients who received adjuvant taxane-based three-drug chemotherapy and two-drug chemotherapy according to pathological lymph node stage (negative, pN0; 1-3 positive, pN1; 4-9 positive, pN2). Results: In 222 pN0 patients, the taxane-based three-drug regimen was not superior to the two-drug regimen. In 159 pN1-2 patients, the taxane-based three-drug regimen significantly improved DFS (5-year DFS rate, 78.2% vs. 46.9%; log-rank p=0.0002) and OS (5-year OS rate, 90.7% vs. 64.3%; log-rank p=0.0001) compared with the two-drug regimen. In a multivariable Cox regression analysis of pN1-2 patients, after adjustment for clinical characteristics, the taxane-based three-drug regimen significantly decreased the risk of recurrence (adjusted HR, 0.37; 95% CI, 0.22 to 0.64; p=0.0004) and death (adjusted HR, 0.22; 95% CI, 0.10 to 0.48; p=0.0001) compared with the two-drug regimen. Conclusions: The taxane-based chemotherapy triplet is superior to the chemotherapy doublet in patients with one to nine positive lymph nodes but not node-negative TNBC in adjuvant setting. These data suggest that pathological lymph node stage leads to de-escalating chemotherapy strategies in operable TNBC patients.

Abstract
OBJECTIVE The purpose of this study was to determine whether lymphatic channels (LCs) and sentinel lymph nodes (SLNs) could be detected on sonographic imaging after subcutaneous, submucosal, or parenchymal injections of a sonographic contrast agent (ie, lymphosonography) in a variety of anatomic locations in several animal models. METHODS Eight swine, 7 canines, 4 rabbits, and a monkey were used for these evaluations. Gray scale pulse inversion harmonic imaging of the LCs and the SLNs was performed after subcutaneous (n = 58), submucosal (n = 14), or parenchymal (n = 8) injections of a tissue-specific sonographic contrast agent (Sonazoid; GE Healthcare, Oslo, Norway). In many instances, blue dye was injected into the same locations as Sonazoid, and surgical dissection of the SLNs and LCs was performed for comparison. Scanning electron microscopy (SEM) of contrast-enhanced and control lymph nodes from 2 rabbits was performed to determine the mechanism of contrast agent uptake and retention within SLNs. RESULTS After subcutaneous, submucosal, or parenchymal contrast agent injections, gray scale pulse inversion harmonic imaging could be used to identify the number and location(s) of LCs and SLNs. After subcutaneous, submucosal, or parenchymal contrast agent injections, Sonazoid was confined to the SLNs (ie, contrast enhancement was not detected in the second-echelon nodes). There was good agreement between the results of lymphosonography and blue dye with surgical dissection in identifying the regional LCs and SLNs. Scanning electron microscopy identified vacuoles representing intact contrast microbubbles within contrast-enhanced SLN macrophages, which were not present in the control lymph nodes. CONCLUSIONS Lymphosonography can be used to detect lymphatic drainage pathways and SLNs in a variety of animal models.

Abstract
AIMS To establish the value of vimentin expression in predicting survival in patients with breast cancer. METHODS Five-year follow-up data were obtained for 68 patients with ductal carcinoma (NOS) of the breast in whom vimentin expression had been studied in fresh frozen and formalin-fixed, paraffin-embedded tissue. The predictive value on survival of tumour size, growth fraction (as assessed using the Ki67 monoclonal antibody), oestrogen receptor status and Bloom and Richardson grade of the primary tumour, and the presence or absence of lymph node metastases in axillary samples, were also studied. RESULTS Twenty-two patients died of their disease within 5 years of diagnosis. Vimentin expression either on frozen or paraffin sections did not provide a statistically significant prediction of survival. On univariate analysis tumour grade, size and the presence of lymph node metastases provided prognostic information. Only lymph node status was of independent prognostic importance on multivariate analysis. CONCLUSIONS Whilst these results confirm the value of established prognostic factors, they do not support the use of vimentin expression in either fresh or fixed tissue for the prediction of survival in ductal carcinoma (NOS) of the breast.

Abstract
Breast cancer is the most common neoplasm affecting women in the Western world with approximately 1 in 11 developing the malignancy and 1 in 30 dying from the disease. For optimum management of these patients, assay of certain biochemical markers is necessary. Clinically, the most useful markers in breast cancer are the estrogen and progesterone receptors that are used to predict response to hormone therapy. Both American and European Expert Panels have recommended routine determination of these steroid hormone receptors in all patients with breast cancer. For surveillance of patients with diagnosed breast cancer, both CA 15-3 and BR 27.29 can be used. Serial determinations of these markers have the potential to preclinically detect recurrent disease and monitor the treatment of advanced disease. However, the benefit of this monitoring on patient outcome or quality of life is not clear. New or potentially new markers for breast cancer include BRCA1 and BRCA2 for selecting patients at high risk of developing breast cancer, urokinase plasminogen activator and PA1-1 for assessing prognosis and HER-2 for predicting response to the therapeutic antibody, Herceptin.

Abstract
The utility of level I and II axillary lymph node dissection in women with primary tumors less than 1 cm in diameter has recently received extensive evaluation. Numerous patients undergo axillary lymph node dissection ultimately to discover no pathological involvement. This study investigates the lymph node status in T1 primary breast adenocarcinoma in our diverse patient population. A retrospective evaluation of patients treated at the Medical Center of Louisiana at New Orleans and the Tulane University Medical Center with breast adenocarcinoma less than or equal to 2 cm was performed. Demographic data and pathological reports were reviewed to obtain breast lesion size and lymph node status. One hundred sixteen patients were found to have T1 lesions. Ethnic distribution was African American 66 per cent; Caucasians 30 per cent; Hispanic 2 per cent; and Asian 3 per cent. Whereas no patients with T1a lesions had positive lymph nodes, 11 per cent of patients with T1b lesions and 36 per cent of patients with T1c lesions had positive lymph nodes. However, in our patient population no patients with tumors less than 1.0 cm. in diameter had positive lymph nodes. Although this may be due to our relatively small sample size axillary lymph node dissection may be unnecessary in this select patient population. For patients with lesions 1.0 cm and greater an axillary lymph node dissection seems to add necessary information for correct treatment in a small percentage of patients. The use of lymphatic mapping with sentinel axillary lymph node biopsy may reduce the number of unnecessary axillary dissections in early breast cancer.

Abstract
The status of the axillary nodes is the strongest known prognostic variable in patients with early breast cancer, and is routinely used in planning postoperative therapy. Conventional axillary lymph node dissection is limited by sampling error and potential morbidity. Sentinel node techniques have revolutionized the management of axillary nodes. Accurate identification and focused histologic evaluation of the sentinel node allow accurate prediction of the tumor status of other axillary nodes, thereby avoiding the morbidity and expense of a complete axillary dissection in node-negative patients. Radiotracer techniques play an important role in the preoperative and intraoperative localization of the sentinel nodes. Optimal localization of the sentinel node requires the use of both preoperative lymphoscintigraphy and intraoperative radiosensitive probes. Lymphoscintigraphy also identifies patients with lymphatic drainage to sites other than the axilla, thereby allowing more appropriate treatment and follow-up in this subset of patients. Procedures for localizing sentinel nodes require an understanding of the kinetics of the radiopharmaceuticals or other tracers used and the detection devices employed in each institution. Both surgical and nuclear medicine personnel should understand these principles, and close cooperation between surgeons, nuclear medicine physicians, and pathologists is essential for the application of sentinel node techniques.

Abstract
BACKGROUND Some authors have stated the undesirability of axillary lymph node dissections for very small breast cancers, because so few of their patients have lymph node metastases (3% for T1a lesions in one series). METHODS Of 6,308 breast cancer cases reviewed from three large urban hospitals 3,077 single primary cases with both axillary dissection and accurate tumor measurements were statistically analyzed. RESULTS For T1a lesions we found axillary metastases to be four times higher (12%) than others have reported. For each tumor size there was a statistically significant difference in the percentage of axillary metastases. There was also a statistically significant difference in the breast cancer-specific survival of patients with different tumor sizes (n = 3,077) at the 3-year, 5-year, 7-year, and 10-year periods. CONCLUSION These results justify axillary node dissections even for very small invasive cancers of the breast, particularly for invasive ductal histology.

Abstract
The management of regional lymph node metastases in breast cancer and gastric cancer is reviewed. Regional lymph node metastasis is a critical prognostic factor in these diseases, but there is an apparent discrepancy in the efficacy of regional lymph node dissection between them. A number of prospective randomized clinical trials have demonstrated that regional lymph node dissection improves the regional control of breast cancer, but does not improve the survival. On the other hand, only retrospective or prospective comparative studies have shown that extended lymph node dissection significantly improves the survival in gastric cancer. Although the discrepancy in the regional lymph node dissection between breast and gastric cancers has been explained by differences in their biological behaviors, caution must still be exercised in drawing conclusions from these norandomized studies.

Abstract
If axillary lymph node metastases were able to be accurately predicted, dissection could be avoided in some patients with breast cancer whose axillary nodes are clinically negative. In this study, we assessed the relationships between histological axillary lymph node metastases and clinical axillary nodal status, tumor size, DNA-ploidy, c-erbB-2 expression, and the score of the argyrophilic nucleolar organizer region. We then attempted to evaluate their predictive values for axillary lymph node metastasis in 173 patients with invasive breast cancer, retrospectively. The clinical and biological variables were significantly correlated with the presence and degree of axillary lymph node metastases. A metastatic index, calculated from the clinical and biological variables, proved especially useful for predicting axillary lymph node metastases in patients whose axillary nodes were clinically negative. However, the predictive abilities were still limited and thus it was concluded that as yet, only axillary dissection can provide accurate information on axillary lymph node metastases.

Abstract
We investigated the relation between Helix pomatia (HPA) staining of primary breast cancer and the presence of axillary (AX) or internal mammary (IM) metastases, and evaluated its predictive value for AX or IM metastases in comparison with the use of clinical variables. There was a significant association between the HPA staining and AX or IM metastases. When HPA staining was regarded as an indicator of AX metastases, a diagnostic accuracy of 72%, a sensitivity of 69% and a specificity of 75% were achieved. As an indicator of IM metastases, these values were 64%, 76% and 62%, respectively. In predicting the presence of AX metastases using a discriminant function with clinical AX status, location of tumour and tumour size, diagnostic accuracy, sensitivity and specificity were 79%, 69% and 87%, respectively. In predicting the presence of IM metastases using the discriminant function with clinical AX status and tumour size, these values were 74%, 71% and 75%, respectively. Therefore, it was concluded that the HPA staining may be useful, but it was equivalent with the discriminant function with clinical variables in prediction of AX or IM metastases.

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
We assessed the relationships among histological axillary (AX) or internal mammary (IM) metastases and clinical and biological variables, and then attempted to evaluate their predictive values for AX and IM metastases in 128 patients with invasive breast cancer. As the results, these clinical and biological variables were significantly correlated with AX and IM metastases. However, a metastatic index calculated from clinical and biological variables was not much better in prediction of the AX metastases than axillary nodal status, whereas it was useful to predict the IM metastases. Thus, the predictive ability was still limited. Since accurate prediction of AX and IM metastases is critical to therapeutic choice, however, further study would be required.

Abstract
In order to evaluate the prognostic importance of clinical and histological node information, we made univariate and multivariate analyses of regional lymph node metastases in 223 patients with operable breast cancer who were surgically treated from 1973 to 1985. Clinical axillary node status, histological involvement of the axillary lymph nodes, their anatomical levels and numbers, and histological involvement of the internal mammary lymph nodes were selected as evaluating prognostic factors. The histological presence or absence of axillary node involvement, especially at the distal level, proved to be the most important prognostic factor. However, neither the anatomical level nor the number of histologically involved axillary lymph nodes appeared to be an important prognostic factor. On the other hand, histological involvement of the internal mammary nodes appeared to be an important and independent prognostic factor. Therefore, we concluded that axillary lymph node dissection with a biopsy of the internal mammary nodes would provide more accurate information about the prognosis of patients with operable breast cancer.

Abstract
The therapy of early breast cancer has been changing during the last decennium. It requires a multi-disciplinary approach and in each of these disciplines improvements have been implemented. The result is that treatment schedules can now be adapted to specific subgroups. In this review early breast cancer is defined as operable disease, using the critera set out by Haagensen. Emphasis is given to describing the new developments in prognostic criteria, since these form the basis for creating subgroups for specific treatment schedules. Distinction is made between the factors relating to growth rate and those relating to metastatic potential. Data on screening promises a beneficial effect of the implementation of screening in national health care programs. Important shifts are seen in treatment schedules; the place of postoperative radiotherapy after classic ablative treatment is being challenged, whereas it plays a major role in the new breast conserving therapy schedules. The data mentioned in the review suggest that a large proportion of 'operable' cases can be treated with breast conservation but details in the technique of breast conserving therapy are still under investigation. They form a major part of the coming prospective studies in breast cancer. Improvements in reconstruction techniques, creating better cosmetic results, make reconstruction more competitive with breast conserving therapy. The use of chemotherapy and endocrine manipulation in early breast cancer has now been clearly confirmed by the overview technique by the Peto-group, thanks to all efforts of individual trialists together.
