Tumor Extension

Context Lymph node status and the number of lymph node (LN) positive for cancer cells are the most important prognostic factors in breast cancer. Extranodal tumor extension (ENTE) has been used as a histopathologic feature to classify patients into high risk versus low risk for local recurrence. However, in the current era of early detection and systemic therapy, the prognostic significance of ENTE is not as well defined in patients with 1 to 3 LNs positive for cancer. Objective To determine whether the amount of tumor burden in an axillary dissection or the presence of ENTE provides any additional information regarding patient outcome in patents with 1 to 3 positive LN results. Design Clinical and pathologic factors were identified for 456 patients with breast cancer at the University of Texas MD Anderson Cancer Center, Houston, who had pT1 tumors and 1 to 3 LNs positive for cancer and were treated by mastectomy, with or without postmastectomy radiotherapy, between 1978 and 2007. Results Of the 456 patients, 257 (56.4%), 141 (31.6%), and 58 (12.7%) patients had 1, 2, or 3 positive LN results, respectively. Extranodal tumor extension was present in 99 patients (21.7%) and was absent in the remaining 357 cases (78.3%). Seventy-six patients (16.7%) received radiation therapy. Patients had both worse overall survival time and disease-free survival when ENTE was present, regardless of the amount, as long as the treatment era was not included in the multivariate analysis (pre-2000 versus post-2000). However, ENTE was no longer significant on multivariate analysis when the year of treatment was taken into account. Conclusions The number of positive LNs remains an important predictor of survival in patients with 1 to 3 positive LN results, but the prognostic significance of ENTE in this cohort of patients has diminished over time.

Node Metastases

Purpose In breast cancer, sentinel lymph node (SLN) biopsy allows the routine performance of serial sections and/or immunohistochemical (IHC) staining to detect occult metastases missed by conventional techniques. However, there is no consensus regarding the optimal method for pathologic examination of SLN, or the prognostic significance of SLN micrometastases. Patients and Methods In 368 patients with axillary node-negative invasive breast cancer, treated between 1976 and 1978 by mastectomy, axillary dissection, and no systemic therapy, we reexamined the axillary tissue blocks following our current pathologic protocol for SLN. Occult lymph node metastases were categorized by pattern of staining (immunohistochemically positive or negative [IHC±], hematoxylin-eosin staining positive or negative [H & E ±]), number of positive nodes (0, 1, > 1), number of metastatic cells (0, 1 to 20, 21 to 100, > 100), and largest cluster size (≤ 0.2 mm [pN0i+], 0.3 to 2.0 mm [pN1mi], > 2.0 mm [pN1a]). We report 20-year results as overall survival (OS), disease-free survival (DFS), and disease-specific death (DSD). Results A total of 23% of patients (83 of 368) were converted to node-positive. Of these, 73% were ≤ 0.2 mm in size (pN0i+), 20% were 0.3 to 2.0 mm (pN1mi), and 6% were more than 2 mm (pN1a). On univariate and multivariate analysis, pattern of staining, number of positive nodes, number of metastatic cells, and cluster size were all significantly related to both DFS and DSD. On multivariate analysis, each of these measures had significance comparable to, or greater than, tumor size, grade or lymphovascular invasion. Conclusion In breast cancer patients staged node-negative by conventional single-section pathology, occult axillary node metastases detected by our current pathologic protocol for SLN are prognostically significant.

Extracellular Matrix Components

CAFs (cancer-associated fibroblasts), the most abundant cell type in breast cancer stroma, produce a plethora of chemokines, growth factors and ECM (extracellular matrix) proteins, that may contribute to dissemination and metastasis. Axillary nodes are the first metastatic site in breast cancer; however, to the present date, there is no consensus of which specific proteins, synthesized by CAFs, might be related with lymph node involvement. The purpose of this study was to perform a systematic review of CAF biomarkers associated with the presence of regional metastasis. PubMed was searched using the words: ‘breast cancer’ and ‘lymph node’ and fibroblast or stroma or microenvironment. After exclusions, eight studies evaluating biomarkers immunoexpression in CAFs and lymph node status were selected. Biomarkers evaluated in these studies may be divided in two groups, according to their ontology: extracellular matrix components [MMP13 (matrix metalloproteinase 13), TIMP2 (tissue inhibitor of metalloproteinases-2), THBS1 (thrombospondin 1), LGALS1 (lectin, galactoside-binding, soluble, 1)] and response to wounding [PDPN (podoplanin), PLAU (plasminogen activator, urokinase), PLAUR (plasminogen activator, urokinase receptor), CAV1 (caveolin 1), THBS1, LGALS1]. A positive expression of MMP13 and LGALS1 in CAFs was associated with enhanced OR (odds ratio) for regional metastasis. Contrariwise, CAV1 positive staining of fibroblasts was associated with decreased OR for nodal involvement. Expression of MMP13, PDPN and CAV1 was further tested in a new series of 65 samples of invasive ductal breast carcinomas by immunohistochemistry and no association between biomarkers expression in CAFs and nodal status was found. It was suggested that breast cancer subtypes may differentially affect CAFs behaviour. It would be interesting to evaluate the prognostic significance of these biomarkers in CAFs from different tumour types.

BackgroundNanoparticle albumin-bound paclitaxel (nab-paclitaxel) as neoadjuvant chemotherapy (NAC) for breast cancer remains controversial. We conducted a retrospective study to compare the efficacy and safety of nab-paclitaxel with those of docetaxel as neoadjuvant regimens for HER2-negative breast cancer.MethodsIn this retrospective analysis, a total of 159 HER2-negative breast cancer patients who had undergone operation after NAC were consecutively analyzed from May 2016 to April 2018. Patients were classified into the nab-paclitaxel group (n = 79, nab-paclitaxel 260 mg/m2, epirubicin 75 mg/m2, and cyclophosphamide 500 mg/m2) and the docetaxel group (n = 80, docetaxel 75 mg/m2, epirubicin 75 mg/m2, and cyclophosphamide 500 mg/m2) according to the drug they received for neoadjuvant treatment. The efficacy and adverse events were evaluated in the two groups.ResultsThe pathological complete response (pCR)(ypT0/isN0) rate was significantly higher in the nab-paclitaxel group than in the docetaxel group (36.71% vs 20.00%; P = 0.031). The multivariate analysis revealed that therapeutic drugs, lymph node status, and tumor subtype were the most significant factor influencing treatment outcome. At a median follow-up of 47 months, disease-free survival (DFS) was not significantly different in those assigned to nab-paclitaxel compared with docetaxel (82.28% vs 76.25%; P = 0.331). The incidence of peripheral sensory neuropathy in the nab-paclitaxel group was higher than that in the docetaxel group (60.76% vs 36.25%; P = 0.008), while the incidence of arthralgia was observed more frequently in the docetaxel group (57.50% vs 39.97%; P = 0.047).ConclusionsCompared with docetaxel, nab-paclitaxel achieved a higher pCR rate, especially those patients with triple-negative breast cancer or lymph node negative breast cancer. However, there was no significant difference in DFS between the two groups. This study provides a valuable reference for the management of patients with HER2-negative breast cancer.

Nonsentinel Lymph Node

Purpose Several models have been developed to predict nonsentinel lymph node (non-SN) status in patients with breast cancer with sentinel lymph node (SN) metastasis. The purpose of our investigation was to compare available models in a prospective, multicenter study. Patients and Methods In a cohort of 561 positive-SN patients who underwent axillary lymph node dissection, we evaluated the areas under the receiver operating characteristic curves (AUCs), calibration, rates of false negatives (FN), and number of patients in the group at low risk for non-SN calculated from nine models. We also evaluated these parameters in the subgroup of patients with micrometastasis or isolated tumor cells (ITC) in the SN. Results At least one non-SN was metastatic in 147 patients (26.2%). Only two of nine models had an AUC greater than 0.75. Three models were well calibrated. Two models yielded an FN rate less than 5%. Three models were able to assign more than a third of patients in the low-risk group. Overall, the Memorial Sloan-Kettering Cancer Center nomogram and Tenon score outperform other methods for all patients, including the subgroup of patients with only SN micrometastases or ITC. Conclusion Our study suggests that all models do not perform equally, especially for the subgroup of patients with only micrometastasis or ITC in the SN. We point out available evaluation methods to assess their performance and provide guidance for clinical practice.

e15797 Background: Duodenal adenocarcinoma is a rare tumor representing approximately 0.3% of all gastrointestinal tract cancers. Prognostic factors in relation to survival outcomes for these patients are sporadically reported in the medical literature. We aimed to evaluate outcomes of patients with duodenal adenocarcinoma who underwent pancreaticojejunostomy treated at Mayo Clinic Rochester from January 1, 2006 to December 31, 2016. Methods: Clinicopathological data of 52 duodenal cancer patients were collected. JMP software was used for statistical analysis. Kaplan-Meier method and log-rank tests were used for survival analysis, and multivariate cox proportional hazards model was used to evaluate the prognostic effect of pertinent clinical variables. All tests were two sided and a P value of < 0.05 was considered significant. Results: The median age at diagnosis was 65.9 years (range 39-81). The median overall survival was 51 months (95% CI 31.3-105.4) and the median progression free survival was 30.4 months with median follow up of 73.4 months. There were 3, 9, 21, and 19 patients with stage I, II, III, and IV disease, respectively. Depth of tumor invasion (p = 0.0156) and lymph node metastasis (p = 0.0441) were associated with overall survival on multivariate analysis. Advanced clinical staging influenced overall survival in univariate analysis, but lost prognostic significance in multivariate analysis. Age, gender, surgical technique, presence of metastases, tumor size, number of lymph nodes removed, location of duodenal segment involvement, and adjuvant treatment had no significant impact on overall survival. Laparoscopic approach did not influence survival but was associated with less hospital days (p = 0.0437). Conclusions: Depth of tumor invasion and lymph node status were associated with improved overall survival in patients with duodenal adenocarcinoma. Laparoscopic procedure decreased the hospital stay without affecting outcomes.

Mskcc Nomogram

Background: Sentinel lymph node (SLN) biopsy accurately stages the axilla, but is time consuming and resource intensive. Nomograms and scoring systems have been developed, based on clinical and pathologic data available before surgery, to attempt to predict the likelihood of lymph node metastasis before surgery. As the management of the axilla in patients with low nodal burden changes, it is also important to predict whether there will be further axillary disease in patients with a positive SLN. Aim: To explore the risk factors for SLN and non-SLN metastasis in Indian women with breast cancer, by analysis of clinical and pathologic data. To assess the validity and clinical utility of two MSKCC nomograms that predicts axillary lymph node status for Western patients. Methods: Clinical data, and pathologic data available from core biopsy, for a consecutive series of women having SLNB was analyzed, and was plotted on two MSKCC nomograms. Univariate analysis was done by χ2 and Fischer exact tests and multivariate analysis was done by logistic regression method. A receiver-operating characteristic (ROC) curve was drawn and predictive accuracy was assessed by calculating the area under the ROC curve (AUC). Results: 34% (89 out of 256) of our patients had SLN positivity. When correlated with SLN metastasis by univariate analysis, LVI (χ2 = 80, P ≤ 0.001), PNI (χ2 = 13.36, P ≤ 0.001), ER+ (χ2 = 6.85, P = 0.009), PR+ (χ2 = 7.1, P = 0.008) and age ( P = 0.03) were significant. However, multivariate analysis showed that age (OR=1.04, P = 0.007) and LVI (OR=0.07, P ≤ 0.001) were identified as independent predictors for SLN metastasis. The area under the ROC curve was 0.772 and it fairly correlated with MSKCC nomogram. Patients with MSKCC scores lower than 38% had a frequency of SLN metastasis of 7.7% (5/65) and this cut-off could be used as a guide for not doing frozen section analysis in this subgroup. Further axillary dissection showed 41% (38 out of 92) had non-sentinel nodes positive. When correlated with non-SLN metastasis by univariate analysis, LVI (χ2 = 8.8, P = 0.003), PNI (χ2 = 6.85, P = 0.009), and extracapsular extension (χ2 = 4.18, P = 0.04) were significant. Number of SLN negative ( P = 0.01), SLN ratio (number of SLN positive/total number of SLN removed) ( P = 0.01) and size of SLN metastasis ( P = 0.002) were significant. However, multivariate analysis showed that only size of SLN metastasis (OR=0.845, P = 0.02) was identified as independent predictor for non-SLN metastasis. The area under the ROC curve was 0.66 and it poorly correlated with MSKCC nomogram. Conclusion: The MSKCC nomogram can provide a fairly accurate prediction of the probability of SLN metastasis, but is not for non-SLN metastasis. An institutional nomogram for non-SLN metastasis, including additional factors such as size of SLN metastasis, may improve prediction.

6599 Background: Many cancer centers routinely re-review outside pathologic specimens. We hypothesized re-review rarely changes patient treatment plans. Methods: Of 1495 patients seen at the University of Virginia with a diagnosis of breast cancer from 2006-2011, the 276 cases with both internal and outside pathology reports comprised the study cohort. Interobserver agreement (kappa coefficient, K) between internal and outside diagnoses were calculated for histopathology, lymph node, margin, ER/PR, and HER2 status. We then evaluated if the change would result in a change in therapy or surveillance per the National Comprehensive Cancer Network (NCCN) guidelines. The effect of region and teaching affiliation of outside institutions was explored. Results: For the 276 cases with re-reviewed pathology at UVA there was absolute agreement for ER/PR and surgical margins, and excellent agreement for lymph node, K= 0.93, and histopathology, K=0.93. Agreement was good for HER2, K=0.83. 3 cases were changed from HER2 positive to negative (2) or intermediate (1). Of 9 changes in histopathology, 2 had a major upgrade: 1 ADH to DCIS; 1 DCIS to carcinoma. 3 had a major downgrade: 2 from DCIS to ADH; 1 from carcinoma to DCIS. 2 cases changed from ALH to LCIS. Lymph node status was changed from positive to negative in one out of 31 reviewed cases. Treatment plan would have changed for all 13, 4.7% of all patients. Changes were made almost exclusively (11/13) if referred from a hospital with no or minor teaching affiliation, including all major histopathology changes and changes in lymph node and HER2 status. Conclusions: Interobserver agreement for breast pathology between pathologists at an NCI designated cancer center and outside institutions was good. However, 4.7% of women had discordant results that would lead to a change in their care. Changes were most common for noninvasive carcinoma and benign atypia. In order to best utilize resources, referral centers may want to consider limiting re-review to the pathology from centers with high risk for discordance.

e12010 Background: The use of adjuvant chemotherapy (CT) in small luminal-like breast cancer (BC) is still heavily debated. International guidelines identify endocrine therapy as the backbone of adjuvant treatment for these patients (pts), while the addition of CT should be limited to high risk cases. The aim of this study was to evaluate the association between patient- or disease-related factors with the prescription of adjuvant CT. Methods: This retrospective study reviewed data from 559 consecutive pts with pT1 ( < 2 cm) luminal-like BC treated between 2004 and 2015 at the Department of Oncology of Udine (Italy). No restrictions were applied regarding lymph node status. The cut-off point of 1% was used to define ER and/or PgR positivity. Factors influencing the prescription of CT were investigated through uni- and multivariate logistic regression with odds ratio (OR) calculation. Prognosis was explored through Cox regression. Results: About thirty percent (173/559) of pts received adjuvant CT. By multivariate analysis, lymph node involvement was highly associated with CT prescription (OR 16.94, 95% CI 7.86-36.50, P < 0.001 for pN1; OR 3.92, 95% CI 1.45-10.58, P = 0.007 for pNmi). Tumor size drove towards the use of CT among pts with pT1c tumors (OR 12.87, 95% CI 1.49-110.88, P = 0.020) but not in pts with pT1b BC (OR 2.38, 95% CI 0.26-21.38, P = 0.437). In addition, a higher CT use was observed in pts with luminal B-like disease (OR 3.79, 95% CI 2.16-6.65, P < 0.001) or in presence of a Ki67 > 14% (OR 1.05, 95% CI 1.03-1.07, P < 0.001). On the contrary, pts with age > 60 years had a very low chance of receiving adjuvant CT (OR 0.09, 95% CI 0.04-0.20, P < 0.001). Notably, the use of CT was not associated with Disease Free Survival or Overall Survival (HR 1.3, 95% CI 0.77-2.17, P = 0.320; HR 1.05, 95% CI 0.56-2, P = 0.866; respectively). Conclusions: Nodal status, tumor size, disease sub-type, Ki67 expression and age are determinants of adjuvant CT prescription in pts with small luminal-like BC. Prospective studies are needed to identify which pts could safely avoid CT without influencing prognosis.

Purpose The aim of this study was to determine the prognostic significance of lymph node micrometastases in patients with breast cancer. Patients and Methods Between September 2000 and January 2004, 3,369 patients with breast cancer were included in a prospective cohort. According to their lymph node status, they were classified in the following four groups: 2,383 were node negative, 107 had isolated tumor cells, 123 had micrometastases, and 756 had macrometastases. Median follow-up time was 52 months. Kaplan-Meier estimates and the multivariate Cox proportional hazard regression model were used to analyze survival. Results Five-year cause-specific and event-free survival rates were lower for patients with micrometastases (pN1mi) than for node-negative (pN0) patients (94.1% v 96.9% and 79.6% v 87.1%, respectively; P = .020 and P = .032, respectively). There was no significant survival difference between node-negative patients and those with isolated tumor cells. The overall survival of pN1mi and pN0 patients did not differ. Conclusion This study demonstrates a worse prognosis for patients with micrometastases than for node-negative patients.
