Abstract Background: Tumor-infiltrating lymphocytes (TILs), which are indicators for monitoring an immune response, are generally mononuclear immunocytes that aggregate with tumors and are thought to have a close relationship with cancer cells. On the other hand, a fibrotic focus (FF) within the stroma of a tumor is a histological formation that plays an important role in the cancer microenvironment with regard to proliferation and development. Here, we focus on TILs that exist within the FF and we have performed pathological evaluations.Methods: Of the 320 patients were treated with neoadjuvant chemotherapy (NAC), 239 subjects who were able to evaluate FF-TILs were targeted. Lymphocytes that infiltrate the FF are FF-TILs.Results: The disease-free survival (DFS) period after NAC for the high-FF-TIL group was found to be significantly longer than that for the low-FF-TIL group for all cases (p < 0.001) and for all subtypes of triple-negative breast cancer (TNBC) (p = 0.001), human epidermal growth factor receptor 2-enriched breast cancer (HER2BC) (p = 0.010), and hormone receptor-positive breast cancer (HRBC) (p = 0.003). In multivariable analysis as well, high-FF-TIL group classification was an independent factor for recurrence after NAC for all cases (p < 0.001, hazard ratio (HR) = 0.198) and all subtypes of TNBC (p = 0.006, HR = 0.172), HER2BC (p = 0.025, HR = 0.135), and HRBC (p = 0.007, HR = 0.228).Conclusions: It is suggested that FF-TILs are a useful factor for predicting recurrence of breast cancer after NAC.Article headings: NAC for breast cancer by evaluation of FF-TILs

BACKGROUND: The immune system is known to play an important role in tumor cell eradication. Although cancer cells were able to escape from the immune system, many studies showed mononuclear inflammatory cell infiltrates known as tumor-infiltrating lymphocytes (TILs) on breast cancer histopathology specimens showed better prognosis, including in disease-free survival (DFS) and chemotherapy responses. OBJECTIVE: This study aimed to reveal the predictive value of tumor-infiltrating lymphocytes (TILs) levels and CD8 expression in invasive breast carcinoma of no special type patients’ samples on response to anthracycline-based neoadjuvant chemotherapy. METHODS: 75 pre-treatment biopsy samples that were diagnosed as invasive breast carcinoma of no special type were evaluated. TILs level determined following recommendations of International TILs Working Group 2014, CD8 expression assessed semiquantitatively after immunohistochemistry staining. Response to anthracycline-based neoadjuvant chemotherapy evaluated clinically using Response Evaluation Criteria in Solid Tumours (RECIST) criteria and pathologically by evaluating hematoxylin and eosin (H&E)-stained slides from mastectomy specimens after 3 or 4 cycles of neoadjuvant chemotherapy. RESULTS: Chi-squared analysis showed a significant relationship between TILs level and CD8 expression with chemotherapy responses clinically (p = 0.011 and p = 0.017 respectively) but not pathologically. Furthermore, the logistic regression test exhibit the predictive value of TILs level was 66.7% and CD8 expression was 64%. CONCLUSIONS: This study results suggest that TILs level and CD8 expression may be added as predictive factors to the response of anthracycline-based neoadjuvant chemotherapy, and oncologists may take benefit in breast cancer patient’s management.

Abstract Background High levels of stromal tumor-infiltrating lymphocytes (sTIL) are associated with increased pathological complete response (pCR) rate and longer survival after neoadjuvant chemotherapy in triple-negative breast cancer (TNBC) patients. Here, we evaluated the value of sTIL in predicting pCR and explored prognosis in TNBC patients treated with neoadjuvant chemotherapy according to body mass index (BMI). Methods sTIL were scored centrally on pretreatment biopsies from 2 retrospective series of nonunderweight TNBC patients (n = 445). sTIL and BMI were considered as binary (sTIL: &lt;30.0% vs ≥30.0%; BMI: lean vs overweight and obese) and continuous variables. Associations with pCR (ypT0/isN0) were assessed using logistic regression, and associations with event-free survival and overall survival were assessed using Cox regressions. Results 236 (53.0%) patients were lean and 209 (47.0%) overweight and obese. pCR was achieved in 181 of 445 (41.7%) patients. Median sTIL was 11.0%, and 99 of 445 (22.2%) tumors had high sTIL. A statistically significant interaction between sTIL and BMI, considered as categorical or continuous variables, for predicting pCR was observed in the multivariable analysis (Pinteraction = .03 and .04, respectively). High sTIL were statistically significantly associated with pCR in lean (odds ratio [OR] = 4.24, 95% confidence interval [CI] = 2.10 to 8.56; P &lt; .001) but not in heavier patients (OR = 1.48, 95% CI = 0.75 to 2.91; P = .26) in the multivariable analysis. High sTIL were further associated with increased event-free survival in lean (hazard ratio [HR] = 0.22, 95% CI = 0.08 to 0.62; P = .004) but not in heavier patients (HR = 0.53, 95% CI = 0.26 to 1.08; P = .08). Similar results were obtained for overall survival. Conclusion BMI is modifying the effect of sTIL on pCR and prognosis in TNBC patients treated with neoadjuvant chemotherapy.

Abstract Objectives Tumor-infiltrating lymphocytes (TILs) have recently emerged as a prognostic factor in breast cancer. In our previous study, we proposed that tumor stroma should also be considered in the calculation of TILs and we introduced tumor infiltration lymphocyte volume (TILV) in triple-negative breast cancer. Methods We assessed the disease-free survival predictive value of TILV in all subtypes of invasive breast carcinoma and compared the predictive value of TILV with TILs. Differences between disease-free survival curves were determined by using the log-rank test, and Kaplan-Meier survival plots were generated for both groups. Results TILV was significantly correlated with disease-free survival in both invasive ductal carcinoma (P = .03) and all subtypes of invasive breast carcinoma (P = .043), whereas TILs failed to show a statistical significance. Conclusions Tumor-stroma ratio needs to be considered in estimation of tumor immunity, and TILV adds more predictive power to TILs.

128 Background: The prognostic importance of tumor-infiltrating lymphocytes (TILs) in triple-negative (TN) and HER2-positive breast cancer has been suggested in recent trials. The aim of this study is to evaluate a relationship between TILs and response to neoadjuvant chemotherapy (NAC) as well as long-term outcome in breast cancer including luminal, TN and HER2 subtypes. Methods: Twenty-seven patients receiving NAC from January 2010 to March 2015 at Inagi Municipal Hospital were analyzed. Intratumoral lymphocytes (ItuLy) and stromal lymphocytes (StrLy) were evaluated in hematoxylin and eosin-stained sections from pretherapeutic core needle biopsies. Lymphocyte-predominant breast cancer (LPBC) was defined as tumors with > 50% of ItuLy or StrLy. Results: A total of 27 patients were divided into 13 luminal (48.1%), 3 TN (11.1%) and 11 HER2 (40.7%) subtypes. The median age was 58 years and the median tumor size was 3.0 cm. A significant correlation between ItuLy (the median percentage: 5%) and StrLy (25%) was observed (Pearson correlation coefficient = 0.628, P< 0.01). LPBC comprised 29.6% (8/27) of total population, with higher frequencies of 33.3% and 54.5% in the TN and HER2-positive subtypes, when compared with 7.7% in luminal subtype (P= 0.044). LPBC group had a significantly higher pathological complete response (pCR) rate of 62.5% (5/8), compared with 5.3% (1/19) for non-LPBC group (P= 0.004). LPBC showed the modest correlation with pCR in luminal (100% (1/1) vs. 0% (0/12), P= 0.077) and HER2-positive subtypes (66.6% (4/6) vs. 25% (1/5), P= 0.175). In TN subtype, neither LPBC nor non-LPBC showed pCR. After a median follow-up of 24.3 months, patients with any TILs were significantly associated with better disease-free survival (DFS) than those without TILs (24.3 vs. 23.6 months, P= 0.016). The most significant impact of TILs on DFS was observed in HER2-positive subtype (23.2 vs. 15.2 months, P= 0.046), whereas TILs did not associate with DFS in luminal and TN subtypes. Conclusions: The presence of TILs was a significant predictor for response to NAC and would provide useful information of prognosis in breast cancer.
