The plasma proteome of 51 non-metastatic breast cancer patients receiving neoadjuvant chemotherapy (NCT) was prospectively analyzed by high-resolution mass spectrometry coupled with nano-flow liquid chromatography using blood drawn at the time of diagnosis. Plasma proteins were identified as potential biomarkers, and their correlation with clinicopathological variables and survival outcomes was analyzed. Of 51 patients, 20 (39.2%) were HR+/HER2-, five (9.8%) were HR+/HER2+, five (9.8%) were HER2+, and 21 (41.2%) were triple-negative subtype. During a median follow-up of 52.0 months, there were 15 relapses (29.4%) and eight deaths (15.7%). Four potential biomarkers were identified among differentially expressed proteins: APOC3 had higher plasma concentrations in the pathological complete response (pCR) group, whereas MBL2, ENG, and P4HB were higher in the non-pCR group. Proteins statistically significantly associated with survival and capable of differentiating low- and high-risk groups were MBL2 and P4HB for disease-free survival, P4HB for overall survival, and MBL2 for distant metastasis-free survival (DMFS). In the multivariate analysis, only MBL2 was a consistent risk factor for DMFS (HR: 9.65, 95% CI 2.10–44.31). The results demonstrate that the proteomes from non-invasive sampling correlate with pCR and survival in breast cancer patients receiving NCT. Further investigation may clarify the role of these proteins in predicting prognosis and thus their therapeutic potential for the prevention of recurrence.

Background This retrospective study investigated the therapeutic benefit of adjuvant endocrine therapy (ET) in breast cancer patients with hormone receptor (HR) status change from positive to negative after neoadjuvant chemotherapy (NAC). Methods From December 2000 to November 2010, 97 eligible patients with a positive-to-negative switch of HR status after NAC were identified. All patients were categorized into 2 groups on the basis of the administration of ET: 57 ET-administered patients and 40 ET-naïve patients. Survival analyses were performed to examine the prognostic value of ET administration as well as other clinical and pathologic variables. Results The administration of ET was significantly associated with improved disease-free survival (p=0.018) in patients with a positive-to-negative switch of HR status. The 5-year disease-free survival rates were 77.0% and 55.5%, respectively, in ET-administered patients and ET-naïve patients. The 5-year overall survival rate for ET-administered patients was also higher than that of ET-naïve patients (81.3% vs. 72.7%, p=0.053), albeit this was statistically insignificant. Conclusions This study revealed that patients with HR altered from positive to negative after NAC still benefit from ET. The HR status should be evaluated not only in specimens obtained during post-NAC surgery but also in specimens biopsied before NAC.

Abstract Background: The impact of the neutrophil–lymphocyte ratio (NLR) on the survival outcomes of patients with early-stage breast cancer is controversial. Methods: We reviewed a series of 115 breast cancer patients who received neoadjuvant chemotherapy followed by surgical treatment. The NLR was calculated using a blood sample obtained before neoadjuvant chemotherapy. The relationships of disease-free survival with the NLR as well as other clinicopathological factors were assessed.Results: There was no significant association between the NLR and disease-free survival in these patients. On the other hand, negative estrogen receptor and progesterone receptor statuses, extended nodal involvement, and advanced TNM stage were significant predictors of shorter disease-free survival.Conclusions: The NLR has little impact on the survival of early-stage breast cancer patients treated with neoadjuvant chemotherapy followed by surgical treatment.

Background: The aim of this study was to evaluate the effectiveness of lapatinib in human epidermal growth factor receptor 2 (HER2)-positive metastatic breast cancer. Methods: We retrospectively reviewed the medical records of patients who received lapatinib for salvage treatment at any line setting from January 1, 2007 to August 31, 2019 at Shandong Cancer Hospital and Institute. Results: A total of 115 (89.1%) patients were included in the study. In the overall cohort, the median disease-free survival (DFS) was 19.0 months; the median progression-free survival (PFS), 6.3 months; and median overall survival (OS), 88.0 months, with 32.2% of patients alive at 5 years. In the second line setting, the median PFS among trastuzumab, lapatinib, and trastuzumab plus lapatinib were 4.2 months, 5.2 months, and 7.3 months, respectively ( P = 0.004). No significant differences between the median PFSs and OSs of the different line salvage treatments with lapatinib was observed (all P > 0.05). For brain metastasis patients, the median PFSs in first line, second line, and more than 3 lines were 7.2 months, 4.5 months, and 6.3 months, respectively. Conclusions: Our findings suggest that patients would benefit more from trastuzumab plus lapatinib than from lapatinib or trastuzumab alone for second line treatment in the advanced stages of the disease. Lapatinib could be used as an alternative selection for HER2-positive metastasic breast cancer patients when there is disease progression after trastuzumab or pyrotinib treatment, which is used as part of China’s national health insurance.

Abstract Obese subjects present higher risk of developing mammary tumors, worse disease free survival and altered response to neoadjuvant chemotherapy (NAC). The circulating levels of the apelin adipokines are increased in obese subjects and are associated with poorer prognosis in cancer patients. In this study, we showed that obesity and tumoral apelin expression are two factors associated with incomplete response to NAC in breast cancer patients.
