Abstract: Objective: To evaluate the clinical value of trastuzumab and chemotherapy in patients with Her2-positive locally advanced breast cancer. Methods: Fifty patients with Her2-positive locally advanced breast cancer admitted to our hospital from March 2017 to March 2018 were randomly selected and divided into control group (conventional chemotherapy) and observation group (conventional chemotherapy + trastuzumab). Results: The total effective rate of the observation group was significantly higher than that of the control group, P < 0.05. There was no significant difference in the incidence of adverse reactions between these two groups. Conclusion: The application of trastuzumab combined with chemotherapy in treating Her2-positive locally advanced breast cancer patients can effectively improve its clinical efficacy and has good safety which is worthy of promotion in clinical applications.

Objective: To investigate the effect of neoadjuvant chemotherapy combined with surgery on locally advanced breast cancer and its prognosis. Methods: One hundred and fifty-four patients with locally advanced breast cancer who were admitted to our hospital from February 2014 to April 2015 were selected as the study subjects. They were divided into an observation group and a control group according to the principle of random equalization, 77 each group. The observation group was treated with TAC scheme, neoadjuvant chemotherapy combined with modified radical resection, and continuously treated with the same scheme after operation until the end of the course of treatment. The control group was treated with modified radical resection and TAC scheme. The clinical efficacy of the two groups was observed, and the perioperative indications, prognosis and occurrence of adverse reactions were compared between the two groups. Results: The total effective rate of the observation group was 76.62%, significantly higher than that of the control group (55.84%, P<0.05). The observation group had shorter operation time and hospitalization time and less bleeding amount compared to the control group (P<0.05). The metastasis rate and recurrence rate of the observation group were significantly lower than those of the control group (P<0.05); there was a significant difference between the two groups (P<0.05). The one-year and three-year survival rates of the observation group were significantly higher than those of the control group (P<0.05). There was no significant difference in the incidence of adverse reactions between the two groups after operation (P>0.05). Conclusion: Preoperative neoadjuvant chemotherapy in combination with TAC scheme can reduce the difficulty of operation, improve the curative effect of patients, significantly improve the prognosis of patients and prolong the survival time, which is worth clinical application. doi: https://doi.org/10.12669/pjms.35.5.310 How to cite this:Zhao H, Zhang J, Lu Y, Jin J.

e11034 Background: Neoadjuvant chemotherapy(NAC)is one of the treatment options for locally advanced breast cancer. In this study, we evaluated the efficacy and safety of 4 cycles of NAC doxorubicine,docetaxel and cyclophosphamide(TAC),correlation between the response to NAC and molecular classification sub-groups and between the pCR and the time to progression(TTP). Methods: This is a prospective study from January 2005 to December 2008.110 pts with locally advanced breast cancer stage III.All pts have received 4 cycles of NAC based on docetaxel 75 mg/m², doxorubicine 50 mg/m² and cyclophosphamide 500 mg/m² every 3 weeks, followed by surgery.101 pts were assessed, since 9 of them have progressed on treatment and came out of the study. Pts were stratified according to age, menopausal status, histopathological analysis (luminal tumors(ER-positive and HER2-negative), triple-negative tumors (TN)and HER2-positive tumors), response to the treatment and survival. The median follow up of patients was 39 months. The statistical study was done using SPSS 17. Results: The median age was 41(23–65).30% of pts were younger than 35 and 80% were premenopausal. 55% luminal tumors(56 pts), 33% HER2 positive(33 pts) and 12 % TN(12 pts).CRR was estimated at 89%(37% of CR and 63% of PR).There were 23, 7% of pCR according to Chevallier’s classification. In luminal, TN and HER2-positive pCR rates were 16%(9 of 56), 66,6%(8 of 12), and 21,2%(7 of 33) respectively. Multivariate analysis showed that the ER status was the only significant predictor of pCR(P = 0.025).HER2 status was not significantly associated with pCR(P= 0,423).TTP was 50 months. In luminal tumors, TN and HER2-positive tumors the TTP was respectively 59, 52 and 49 months. There was not a significant difference in TTP between the pCR(51 months) and the non-pCR group(44 months)(CI 95, p= 0.109).Grade III/IV toxicity included neutropenia(22%), febrile neutropenia(6,5%), mucositis(13%), and diarrhea(4%). Conclusions: Breast cancer occurs in young women in Algeria. In this study, neoadjuvant TAC was effective and well tolerated. The ER status was the only significant predictor of pCR. The molecular classification group with the highest percentage of pCR was the TN group. pCR was not associated with a better prognosis.

Background The prognostic impact of neoadjuvant chemotherapy (NAC) on the receptor expression status in patients with locally advanced breast cancer (LABC) is still not fully understood. We aimed to evaluate the changes in hormone (estrogen and progesterone) receptor (HR) and human epidermal growth factor receptor 2 (HER2) status post-NAC and their correlation with survival. Methods Patients with LABC who have received NAC between 2008 and 2015 and have been followed up till December 2019 at the Oncology Center, King Saud University, KSA were analyzed retrospectively. biomarker analysis of ER, PR & HER2 were done using immunohistochemistry (IHC) and Fluorescent in situ hybridization. Results Ninety-one patients fulfilled the inclusion criteria. HR status changed in 21(23.1%) patients, with a significant difference between patients with stable receptors and those with any receptor conversion; p = 0.000. Five (5.5%) initially HER2 negative tumors became HER2 positive and 10 (11%) initially HER2 positive tumors became HER2 negative after NAC. The difference in HER2 expression level before and after NAC was not statistically significant (p = 0.302). Univariate analysis relating patients’ characteristics and 10-years disease-free survival (DFS) showed only significant correlations with the expressions of ER, PR, and any receptor conversion, (ER and/or PR) p< 0.001, p< 0.001, and p = 0.001; respectively. In the univariate analysis, none of the clinicopathological features showed a significant correlation with the OS except for the molecular subtypes P<0.001. Conclusions Patients with LABC have significant changes in the ER and PR receptor status following NAC. Post-NAC expressions change of ER and PR (ER and/or PR) are correlated to DFS. Retesting of the hormone receptors should be considered after NAC in Saudi patients with LABC.

The present phase III trial was carried out to verify whether a kinetic recruitment induced by low doses of diethylstilbes-trol (DES) could increase the killing efficacy of chemotherapy in patients with locally advanced breast cancer. One-hundred and seventeen untreated patients with locally advanced breast cancer (stage IIIA/IIIB) were randomized to receive 3 courses of primary chemotherapy consisting of cyclophosphamide (600 mg/m2 i.v.), doxorubicin (50 mg/m2 i.v.) and fluorouracil (600 mg/m2 i.v.) (CAF) on day 1, or DES-CAF (DES, 1 mg orally days 1-3, CAF on day 4). The courses were repeated every 3 weeks. The patients who achieved an objective response were submitted to mastectomy followed by 3 courses of CAF alternated with 3 courses of CMF (cyclophosphamide, 600 mg/m2 i.v.; methotrexate, 40 mg/m2 i.v.; fluorouracil, 600 mg/m2 i.v.), with or without DES. The two treatment arms were well balanced in terms of clinical and pathologic features. There was no significant difference in response rates to induction chemotherapy between the two treatment arms (objective response rate, 63.3% for CAF and 56.1% for DES-CAF). Median overall survival was 49 and 47 months and median progression-free survival was 24 and 21 months for CAF and DES-CAF patients, respectively. Toxicity was not significantly different in the two groups, with the exception of leukopenia: DES chemotherapy was significantly more myelotoxic than the standard treatment, which resulted in a significant reduction in the actual dose intensity. In spite of the attractive experimental evidence, we conclude that so far there is no clinical advantage in the combination of estrogen and chemotherapy. Further research is needed to investigate different schedules of chemotherapy and hor-mones, or to test the possibility of combining various mitogens.
