Pam50 Subtype

544 Background: We investigated the prognostic role of the PAM50 HER2-enriched (HER2-E) subtype in HER2+ early breast cancer enrolled in the randomized Phase III ShortHER trial. Methods: The ShortHER study randomized 1254 HER2+ early breast cancer patients to receive 9 weeks vs 1 year of adjuvant trastuzumab combined with chemotherapy. Gene expression measured using nCounter platform was available for 438 surgical samples. Intrinsic subtyping was determined using the research-based PAM50 predictor. Metastasis-free survival (MFS) was calculated from randomization to distant disease recurrence or death (median follow up 72 months). Uni- and multi-variable analysis were performed using Cox models. Results: PAM50 subtype distribution was: HER2-E 53% (N = 233), Luminal A 20% (N = 87), Luminal B 10% (N = 43), Normal-like 11% (N = 48) and Basal-like 6% (N = 27). HER2-E subtype was associated with hormone receptor-negative status (p < 0.001) and TILs ≥20% (p < 0.001), but not with stage and age ( < or ≥60 yrs). HER2-E subtype was associated with worse MFS vs other PAM50 subtypes overall (HR 2.78, p = 0.001), in the short (HR 2.24, p = 0.046), and in the long arm (HR 4.04, p = 0.011). Multivariable Cox model confirmed the independent prognostic value of HER2-E subtype (Table). HER2-E subtype added significant prognostic value on top of clinicopathological variables (Likelihood ratio test p < 0.001). Conclusions: HER2-E intrinsic subtype is an independent prognostic factor for HER2+ early breast cancer patients treated with adjuvant chemotherapy and trastuzumab. Integration of PAM50 subtype in prognostic algorithms can help refine risk stratification. These findings warrant independent validation. Clinical trial information: NCT00629278. [Table: see text]

670 Background: Bcl-2 is an anti-apoptotic marker and regulated by hormonal receptor pathways in breast cancer. We performed this study to assess the prognostic significance of ER, PR, p53, c-erbB2, bcl-2, Ki-67, and EGFR as a marker for relapse in breast cancer patients who received same adjuvant therapy in a single institution. Methods: A cohort of 154 curatively resected breast cancer patients who had 4 lymph nodes or more and received doxorubicin and cyclophosphamide followed by paclitaxel (AC/T) as adjuvant chemotherapy was analyzed for clinicopathologic characteristics including disease-free survival (DFS). Patients with ER and/or PR expression received 5 years of tamoxifen following AC/T. The markers were analyzed by immunohistochemistry. Results: Median f/u duration was 25 months and 32 patients (20.8%) had recurrences. Stage (IIIa vs. IIIc) affected recurrences significantly, however, types of surgery, histology, histologic grade, presence of endolymphatic emboli, or close resection margin did not. Among the immunohistochemical markers, bcl-2 expression was the only one to be associated significantly with prolonged DFS (median 54 mo in bcl-2 (−) vs. not reached in bcl-2 (+); p=0.016). Furthermore, bcl-2 was an independent prognostic factor for DFS in multivariate analysis. Bcl-2 expression was significantly correlated with ER expression (p<0.001), and inversely correlated with c-erbB2 overexpression (p=0.027). Patients with both ER and bcl-2 expression had a longer DFS compared to the other patients (not reached vs. 54 mo, p=0.019). Patients with bcl-2 expression had a significantly longer DFS even in ER (+) subgroups (not reached vs 54 mo; p=0.011). Patients with c-erbB2 overexpression, ER (−) and bcl-2 (−) had a shorter DFS than the others (38 mo vs. not reached; p=0.029). Conclusions: In our homogenous patient cohort, bcl-2 expression was correlated with ER expression, and inversely correlated with c-erbB2 overexpression. Bcl-2 was an independent prognostic factor for DFS in curatively resected stage III breast cancer patients. No significant financial relationships to disclose.

Background and aims: Male breast cancer is an uncommon disease. The benefit of adjuvant chemotherapy in the treatment of male breast cancer patients has not been determined. The aim of this study was to explore the value of adjuvant chemotherapy in men with stage I–III breast cancer, and we hypothesized that some male patients may safely skip adjuvant chemotherapy. Methods: Male breast cancer patients between 2010 and 2015 from the Surveillance Epidemiology and End Results database were included. Univariate and multivariate Cox analyses were used to analyse the factors associated with survival. The propensity score matching method was adopted to balance baseline characteristics. Kaplan–Meier curves were used to evaluate the impacts of adjuvant chemotherapy on survival. The primary endpoint was survival. Results: We enrolled 514 patients for this study, including 257 patients treated with chemotherapy and 257 patients without. There was a significant difference in overall survival (OS) but not in breast cancer-specific survival (BCSS) between the two groups ( p < 0.001 for OS and p = 0.128 for BCSS, respectively). Compared with the non-chemotherapy group, the chemotherapy group had a higher 4-year OS rate (97.5% versus 95.2%, p < 0.001), while 4-year BCSS was similar (98% versus 98.8%, p = 0.128). The chemotherapy group had longer OS than the non-chemotherapy group among HR+, HER2–, tumour size >2 cm, lymph node-positive male breast cancer patients ( p < 0.05). Regardless of tumour size, there were no differences in OS or BCSS between the chemotherapy and non-chemotherapy cohorts for lymph node-negative patients (OS: p > 0.05, BCSS: p > 0.05). Adjuvant chemotherapy showed no significant effects on both OS and BCSS in patients with stage I (OS: p = 0.100, BCSS: p = 0.858) and stage IIA breast cancer (OS: p > 0.05, BCSS: p > 0.05). Conclusion: For stage I and stage IIA patients, adjuvant chemotherapy could not improve OS and BCSS. Therefore, adjuvant chemotherapy might be skipped for stage I and stage IIA male breast cancer patients.
