Background: Genetic variations in oxidative stress-related genes may alter the coded protein level and impact the pathogenesis of breast cancer. Methods: The current study investigated the associations of functional single nucleotide polymorphisms in the NFE2L2, HMOX1, P21, TXNRD2, and ATF3 genes with the early-stage breast cancer clinicopathological characteristics and disease-free survival, metastasis-free survival, and overall survival. A total of 202 Eastern European (Lithuanian) women with primary I–II stage breast cancer were involved. Genotyping of the single nucleotide polymorphisms was performed using TaqMan single nucleotide polymorphisms genotyping assays. Results: The CA+AA genotypes of P21 rs1801270 were significantly less frequent in patients with lymph node metastasis and larger tumor size ( P=0.041 and P=0.022, respectively). The TT genotype in ATF3 rs3125289 had significantly lower risk of estrogen receptor (ER), progesterone receptor (PR) negative, and human epidermal growth factor receptor 2 (HER2) positive status ( P=0.023, P=0.046, and P=0.040, respectively). In both, univariate and multivariate Cox analysis, TXNRD2 rs1139793 GG genotype vs. GA+AA was a negative prognostic factor for disease-free survival (multivariate hazard ratio (HR) 2.248; P=0.025) and overall survival (multivariate HR 2.248; P=0.029). The ATF3 rs11119982 CC genotype in the genotype model was a negative prognostic factor for disease-free survival (multivariate HR 5.878; P=0.006), metastasis-free survival (multivariate HR 4.759; P=0.018), and overall survival (multivariate HR 3.280; P=0.048). Conclusion: Our findings suggest that P21 rs1801270 is associated with lymph node metastasis and larger tumor size, and ATF3 rs3125289 is associated with ER, PR, and HER2 status. Two potential, novel, early-stage breast cancer survival biomarkers, TXNRD2 rs1139793 and ATF3 rs11119982, were detected. Further investigations are needed to confirm the results of the current study.

We investigated the prevalence of anaemia (haemoglobin concentration < 12 g/dl) in 336 women with early-stage breast cancer and its association with other known prognostic factors. The median follow-up period was 60.5 months (range 9-123 months). Seventy-nine women (23.5%) had a low pre-treatment haemoglobin concentration, but anaemia was not correlated with age, tumour size, nodal status, histological grade or hormone receptor status. Univariate analysis revealed that disease-free survival and overall survival were shorter in patients with anaemia at the time of diagnosis than in patients with normal haemoglobin concentrations. Anaemia remained a significant prognostic factor for disease-free survival and overall survival in the multivariate analysis (relative risk, 1.884 and 1.785, respectively). These results suggest that pre-treatment haemoglobin concentration is an independent prognostic factor in patients with early-stage breast cancer.

Background: Breast cancer is a disease which have a variety of important features whose different phenotype only partially summarize the underlying biological complexity. Treatment choices in routine management principally rely on the clinical and pathological characteristics of the disease, although molecular classification currently offers information alongside that provided by clinical and pathological examination. The decision to offer adjuvant chemotherapy to patients is not easy and the knowledge of prognostic factors is mandatory. Ki 67 plays an important role in this context, especially in patients who do not have access to genetic signatures. Aim of the work: This study aims to evaluate the value of Ki67 as a prognostic factor in relation to disease free survival and other clinico-pathological factors in Egyptian females with early stage breast cancer. Patients and Methods: Type of study: This is a retrospective cohort study. Study population: It consisted of 124 patients diagnosed with early stage breast cancer. Study Period: They were diagnosed between January 2011 and December 2015. Study setting: The patients were following up in Ain Shams University Hospital clinical oncology department. Information were manually retrieved from the records of the clinical oncology department at Ain Shams university hospitals. Clinical and pathological tumor characteristics were collected using patient charts and pathology reports. Results: Our study showed a significant relation between Ki67 index and estrogen receptors, progesterone receptors and Her2 neu status. Ki67 was found to be statistically significantly correlated to intrinsic subtypes. Our study was unable to find out the effect of Ki67 on disease free survival. Cox regression analysis revealed a statistical significant influence of estrogen receptors status on disease free survival. It also revealed statistical prognostic effect of progesterone receptors and Her2 status on disease free survival. Covariate analysis of results in our study showed that tumor with T4 stage has a significant prognostic effect on disease free survival. Conclusion: ki67 index may have a prognostic role in management of early stage breast cancer in relation to other prognostic markers like hormone receptor status and HER2neu expression. Moreover, immunohisto-chemistry-based subtyping is extremely important to classify breast carcinoma into molecular subtypes that vary in clinic-pathological features and would lead to different prognosis. Thus, molecular subtyping is essential for breast carcinoma management.

Abstract Background While numerous randomized controlled trials have demonstrated long-term survival rates for patients with early-stage breast cancer treated with breast-conserving surgery (BCS) comparable to mastectomy, the latter remains the most prevalent surgical option to treat early-stage breast cancer in Thailand. Objectives To investigate the potential determinants affecting the decision on selecting BCS or mastectomy for the treatment of early-stage breast cancer and to compare the disease-free survival and overall survival between the treatments using a propensity score-matched analysis. Methods Patients diagnosed nonmetastatic breast cancer at the Queen Sirikit Breast Cancer Center from January 2006 to December 2015, were retrospectively identified and grouped intro patients who received BCS or mastectomy. After propensity score matching, 356 BCS and 209 mastectomy patients were identified, and statistical analysis was conducted to determine treatment selection factors and compare disease-free and overall survival. Results Disease-free survival and overall survival in months comparing BCS and mastectomy were not statistically different with P values of 0.11 and 0.77, respectively. Determinants of treatment selection found that younger age, surgeon preference, smaller tumor size, and lower tumor grade were statistically significant factors in the selection of BCS over mastectomy. The majority of surgeons had a preference for one treatment over the other (P < 0.001). Conclusion The outcome of BCS is comparable to mastectomy in early-stage breast cancer patients. Key determinants affecting the selection of treatment were identified to be patient age, characteristics of the tumor, and surgeon’s preference.

Abstract Objective To evaluate pathological complete response as a surrogate endpoint for disease-free survival and overall survival in regulatory neoadjuvant trials of early stage breast cancer. Design Systematic review and meta-analysis. Data sources Medline, Embase, and Scopus to 1 December 2020. Eligibility criteria for study selection Randomised clinical trials that tested neoadjuvant chemotherapy given alone or combined with other treatments, including anti-human epidermal growth factor 2 (anti-HER2) drugs, targeted treatments, antivascular agents, bisphosphonates, and immune checkpoint inhibitors. Data extraction and synthesis Trial level associations between the surrogate endpoint pathological complete response and disease-free survival and overall survival. Methods A weighted regression analysis was performed on log transformed treatment effect estimates (hazard ratio for disease-free survival and overall survival and relative risk for pathological complete response), and the coefficient of determination (R 2 ) was used to quantify the association. The secondary objective was to explore heterogeneity of results in preplanned subgroups analysis, stratifying trials according treatment type in the experimental arm, definition used for pathological complete response (breast and lymph nodes v breast only), and biological features of the disease (HER2 positive or triple negative breast cancer). The surrogate threshold effect was also evaluated, indicating the minimum value of the relative risk for pathological complete response necessary to confidently predict a non-null effect on hazard ratio for disease-free survival or overall survival. Results 54 randomised clinical trials comprising a total of 32 611 patients were included in the analysis. A weak association was observed between the log(relative risk) for pathological complete response and log(hazard ratio) for both disease-free survival (R 2 =0.14, 95% confidence interval 0.00 to 0.29) and overall survival (R 2 =0.08, 0.00 to 0.22). Similar results were found across all subgroups evaluated, independently of the definition used for pathological complete response, treatment type in the experimental arm, and biological features of the disease. The surrogate threshold effect was 5.19 for disease-free survival but was not estimable for overall survival. Consistent results were confirmed in three sensitivity analyses: excluding small trials (<200 patients enrolled), excluding trials with short median follow-up (<24 months), and replacing the relative risk for pathological complete response with the absolute difference of pathological complete response rates between treatment arms. Conclusion A lack of surrogacy of pathological complete response was identified at trial level for both disease-free survival and overall survival. The findings suggest that pathological complete response should not be used as primary endpoint in regulatory neoadjuvant trials of early stage breast cancer.

PURPOSE To determine whether perioperative polychemotherapy (PeCT) can significantly prolong the overall survival of women with early-stage breast cancer. METHODS A meta-analysis that used updated individual patient data from all available randomized trials of PeCT, both published and unpublished, was conducted. Data on 6,093 patients (1,124 deaths and 1,912 recurrences) from five clinical trials were available (median follow-up duration, 5.3 years; maximum, 11.3 years). RESULTS No significant effect of PeCT on overall survival was observed. However, patients who received PeCT had a significantly longer disease-free survival (hazards ratio [HR], 0.89; 95% confidence interval [CI], 0.82 to 0.98; P = .02). Time to local recurrence was significantly prolonged in the PeCT arm (HR, 0.68; 95% CI, 0.58 to 0.80; P < .0001). Likewise, there was a borderline significant difference in favor of PeCT in terms of time to distant metastases (HR, 0.90; 95% CI, 0.81 to 1.00; P = .05). Subgroup analyses suggest that node-negative women benefited the most from treatment. CONCLUSION At present, there is no evidence that PeCT is able to prolong overall survival in patients with early-stage breast cancer; however, further follow-up evaluation is required. PeCT significantly prolongs disease-free survival, especially in node-negative women, which emphasizes once more the need for clinical trials in this subgroup.
