Filter by:The purpose of this study is to determine whether exemestane plus everolimus are effective in the treatment of patients who have achieved disease stabilization after induction chemotherapy for hormone-receptor positive metastatic breast cancer.
The p63 gene is a recently discovered member of the p53 family located at chromosome 3q27Many studies have reported that overexpression of p63 can mimic p53 activities by binding DNA, activating transcription, and inducing apoptosis. Various studies proved p63 as a marker of basal cells in normal salivary glands, breast, prostate, respiratory and squamous epithelia, and of tumor cells from various malignancies. Still, p63 has been the subject of relatively few studies in lung adenocarcinoma, and breast carcinoma, and no study has described the correlation of p63 with pancreatic ductal adenocarcinoma. In the current study, we aim to evaluate the prognostic value of the expression of p63 in the lung adenocarcinoma, breast adenocarcinoma, and pancreatic ductal adenocarcinoma. We will achieve this aim by collecting clinical data retrospectively from the patients' medical records as well as assessing the histological sections and performing immunohistochemical staining for p63.
This is a single-center, open-label, randomized, prospective study evaluating the safety and efficacy of HO/02/02 20µg topically applied daily for 15 minutes (with gauze) on treatment fields vs. standard of care (SoC), Aloe Vera treatment
S-1 is a newly developed novel oral dihydrouracil dehydrogenase inhibiting fluoro-pyrimidine drug consisting of i M tegafur (FT), 0.4 M 5-chloro-2, 4-dihydroxypyrimidine (gimeracil), and 1 M potassium oxonate (oteracil), with efficient antitumor activity and low gastrointestinal toxicity. Several studies have proved the safety and efficacy of single agent S-1 in metastatic breast cancer. This study is designed to further investigate and compare the efficacy and safety of Epirubicin-cyclophosphamide-S-1(ECS) vs. Epirubicin-cyclophosphamide-5-fluorouracil (ECF) as neoadjuvant chemotherapy in patients with local advanced breast cancer.
RATIONALE: Adjuvant chemotherapy has been proven to reduce significantly the risk for relapse and death in women with operable breast cancer.In the North American Inter-Group factorial trial design (CALGB 9741) the concept of dosedense adjuvant chemotherapy was further tested in patients with node-positive breast cancer.Weekly paclitaxel after standard adjuvant chemotherapy with epirubicin and cyclophosphamide improves disease-free and overall survival in women with breast cancer.Investigators asked if dose-dense 2-week intertreatment intervals (supported by the use of granulocyte-colony stimulating factor) were better than the conventional inconvenient weekly intervals.
Human epidermalgrowth factor receptor-2(HER2) negative Luminal B subtype breast cancer patients are included. After 4 cycles of Capecitabine combined with Docetaxel(XT) protocol neoadjuvant chemotherapy ,those who reach partial response(PR) but not pathological complete response(pCR) are randomly divided into the group treated with XT protocol and the group with Capecitabine combined with Epirubicin and Cyclophosphamide(XEC) protocol ,then compare the disease free survival(DFS) and overall survival(OS) of two subgroup.
This study is designed to investigate the efficacy of carboplatin, as a post-operative adjuvant chemotherapy for triple negative breast cancer patients who have pathologic residual cancer after the preoperative chemotherapy.
Breast cancer is a heterogeneous disease and can be classified into several distinctive subgroups. Triple-negative breast cancer(TNBC) is defined by lack of estrogen(ER), progesterone(PR) immunoreactivity and lack of human epidermal receptor-2(HER2) overexpression. TNBC comprises around 15% of all breast cancer and is characterized by its aggressive clinical behavior and insensitivity toward available targeted treatment strategies such as endocrine and anti-HER2 therapies.Although TNBC is sensitive to chemotherapy,early relapse with metastatic disease is common and the prognosis is poor. Development Of novel treatment strategies is,therefore,needed and the study of other potential targets in TNBC,like tyrosine kinase receptors,is a topic of interest. Epidermal Growth Factor Receptor(EGFR) is a transmembrane receptor tyrosine kinase that encoded by cell erythroblastosis virus oncogene B1(C-erbB1) and belongs to the HER/Erythroblastosis virus oncogene B(ErbB) family. By several signal pathways,EGFR regulates cell proliferation, differentiation, apoptosis, invasion,and angiogenesis,and serves as a poor prognostic factor.EGFR is overexpressed in a variety of malignancies including TNBC.Gene expression profiling and immunohistochemical studies have indicated that 40 to 60% of TNBCs exhibit EGFR expression and gene amplification was found in 18% of this subgroup,but EGFR mutation was rare in TNBC. By far,the role of gefitinib, an EGFR tyrosine kinase inhibitor(TKI),in the metastatic TNBC has not been identified. Most clinical trials about EGFR TKIs in the breast cancer have one or more limitations including:1) the study population had received heavily pretreatment; 2)the enrolled patients included several subgroups of breast cancer; 3)the expression of EGFR was not clear in the enrolled patients. Here, the investigators launch a prospective clinical trial, and about 50 patients with triple-negative,EGFR positive metastatic breast cancer that have received at least second line therapy will be enrolled. these patients will be treated with gefitinib, the toxicity and effects of gefitinib will be recorded prospectively to evaluate the role of gefitinib in the metastatic TNBC.
Axillary dissection is the standard treatment for breast cancer patients with positive nodes. However, seroma formation after axillary dissection remains the most common early complication to breast cancer surgery. It can delay the initiation of adjuvant therapy, predispose to wound infection, delay wound healing and has also been linked to arm lymphoedema. Based on some studies and our experience that vacuum assisted closure （VAC）is effective in complex wound failures following axillary dissection and groin dissection, we use VAC to prevent seroma formation after extensive axillary dissection. This study is aimed to evaluate the efficacy, safety and economics benefits of early VAC application on postoperative complications and wound healing after extensive axillary dissection in comparison to conventional suction drain.
- Assess the attitudes and feelings of premenopausal Latin American women towards the risk of loss their fertility by adjuvant chemotherapy. - Correlate the attitudes with other variables including age at diagnosis, already having children, number of children, level of instruction, marital status, frequency of menstrual cycle.
