Filter by:- This is a prospective, single-center, non-randomized, non-controlled study. - The estrogen receptor (ER), progesterone receptor (PgR), HER2 status and Ki67 index of CNB specimen are critical biomarkers for making neoadjuvant therapy strategy in invasive breast cancer. The concordance of these biomarkers between CNB and surgical specimen was varied in previous retrospective reports. The aim of this study is to determine the discordance of these biomarkers between CNB and surgical specimen and the influence of making treatment strategy by the discordance.
Chloroquine (CQ) is a well known, well tolerated medication that has been used for many years traditionally for arthritis, lupus, and malaria. It has anti-inflammatory properties but is often the drug of choice for arthritis and malaria due to its few side effects. Recently, laboratory investigations have proven that CQ may potentially have anti-cancer properties, by inhibiting a process which allows cancers such as breast cancer to continue to grow (a process known as "autophagy"). Therefore, this study will look at how well CQ can inhibit the growth of breast cancers in patients while waiting for surgery.
This is a prospective examination of tumor material of breast cancer patients randomized into the FinHer-trial (= (= Comparison of vinorelbine and docetaxel and trastuzumab as adjuvant treatments of breast cancer patients wirh a high risk of cancer recurrence). The formalin-fixed, paraffin-embedded tissue samples will be analysed for Estrogen receptor 1 (ESR1), progesterone receptor (PgR), Human epidermal growth factor receptor 2 (HER2) and Antigen Ki-67 (Ki-67) with the molecular in vitro diagnostic kit MammaTyper™. According to the new subtyping the 5 year Distant disease free survival (DDFS) and Overall survival (OS) will be re-evaluated.
The purpose of this study is to determine the optimal time to use the Tumor RNA Disruption Assay (RDA) as a predictor of pathological complete response (pCR) in patients with breast cancer treated with neoadjuvant chemotherapy. This is important because the earlier non-responders are identified, the greater is the impact of reducing side effects of ineffective treatments. The study hypothesis is that the RDA score will accurately predict for tumor response after one cycle of chemotherapy.
To compare the effect of four and a half days treatment of a range of doses of AZD5363 on selected markers of the AKT pathway and anti-proliferation compared with placebo in oestrogen receptor positive breast cancers. To assess the tolerability of four and a half days treatment of AZD5363.
The purpose of this research study is to better understand the reasons why or why not breast cancers are destroyed by standard chemotherapy. This information will be used to develop new and better cancer therapies.
The purpose of this project is to examine whether treatment with vandetanib has an effect on the tumor cells in breast cancer by examining tissue markers.
In this prospective study the investigators sought to evaluate the feasibility of using the genomic signature - Genomic Grade Index (GGI) - in routine clinical practice and its impact on treatment recommendations.
The purpose of this study is to find out if the effect of mometasone furoate is any different from Eucerin in decreasing the severity of redness of the skin during irradiation, preventing the skin from peeling, or reducing the amount of irritation the patient reports during treatment.
Participants undergoing radiation after breast conserving surgery for an early breast cancer (either Ductal Carcinoma In Situ (DCIS), or Early Stage Invasive breast cancer), and are at increased risk of developing a skin reaction because of their large breast size. After breast conserving surgery (also known as a 'lumpectomy'), women with either DCIS or early stage invasive breast cancer receive radiation to the breast to decrease the risk of cancer recurrence. Breast radiation is usually done with women lying on their back ("supine"). Some women develop temporary breakdown of the skin (moist desquamation). This skin reaction can be painful and has been linked to long term side effects such as chronic pain and decreased quality of life. This study is being done because women with large breasts have higher rates of skin breakdown (called 'moist desquamation') and breast pain during and shortly after radiation therapy is complete. It is unclear if such skin reactions and pain would be improved by alternating treatment position - namely lying on your belly ("prone") during their radiation treatment.
