Active clinical trials for "Breast Neoplasms"

The number of surgical procedures performed in ambulatory hospitalization for cancers of the skin or breast is increasing for medical and economic reasons. But the protocols of care and the clinical pathways are poorly adapted for elderly patients with physical or cognitive impairment. The goal of this study is to test the impact of an oncology ambulatory surgical care in patients aged 75 years or older, with breast or skin cancer and treated in Henri Mondor hospital on the increase in the proportion of patients operated on an outpatient basis

Breast cancer is the most common type of cancer among women and covers 25% of all cancers. After mastectomy and reconstruction, many patients develop various upper extremity complications such as joint movement limitation, pain, lymphedema, and axillary cord. Because of such upper extremity problems, evaluation and treatment of upper extremity functions are important. Upper extremity functions are generally evaluated with questionnaires filled out by the patients themselves and which reflect their own perspectives subjectively. However, these questionnaires cannot reflect the observations and evaluations of the clinicians. Performance tests are important for clinicians to make decisions. With this study, we want to examine the usability of the FIT-HaNSA test in the evaluation of upper extremity functions in patients with breast cancer. Our hypothesis; The FıtHaNSA test is successful in evaluating the upper extremity function in patients with breast cancer.

In addition to axillary lymph node (ALN), internal mammary lymph node (IMLN) chain is also the first-echelon nodal drainage site for metastasis and it provides important prognostic information in breast cancer patients. However, decision about local treatment of IMLN is still being made based on ALN status. The 2016 National Comprehensive Cancer Network Guidelines recommend internal mammary lymph node irradiation for patients with more than 4 positive ALNs (category 1), and strongly consider irradiation for patients with 1 to 3 positive ALNs (category 2A). Therefore, there will be patients in positive ALN subgroup who just face complications of an unnecessary radiation to IMLN and there will be patients in negative ALN subgroup who do not receive adjuvant radiation therapy they really need. Thus, these inclusion criteria of National Comprehensive Cancer Network might lead to over-treatment and under-treatment. Internal mammary sentinel lymph node biopsy (IM-SLNB) provides a less invasive method of assessing the IMLN than surgical dissection. However, low visualization rate of IM-SLN has been a restriction of IM-SLNB. A modified radiotracer injection technique was established in our previous study. This technique could significantly improve the IM-SLN detection rate. The investigators have validated the accurate of the hypothesis and the modified radiotracer injection technique in the previous study. For axillary sentinel lymph node biopsy, the success rate and the accuracy are the most important technical indicators. The relatively lower false-negative rate is a precondition for the widely application of SLNB. Axillary SLNB needs to be accomplished with the cooperation of multi-disciplinary teamwork, including the breast surgery, the radiologist, the nuclear medicine doctor and the pathologist, in order to obtain a better success rate and a lower false-negative rate. Our previous studies confirmed that the modified radiotracer injection technique can greatly improve the IM-SLN detection rate. However, whether the IM-SLNB based on the modified radiotracer injection technique has a low false negative rate or not still need to be confirmed by a further validation research. Furthermore，recently, the investigators propose that if IM-SLN is the only metastatic lymph node and there would be no positive node else in IMLN chain, the radiotherapy and its associated complications could be avoided in these patients. On the other hand, if there is the presence of metastatic non-sentinel lymph node (NSLN) in IMLN chain after IM-SLNB, it is important to predict the risk of IM-NSLN metastasis in IM-SLN positive patients. As there is currently no such model, a predictive model for IM-SLN positive patients to avoid radiotherapy is needed in this situation. Therefore, a new study will be conducted to verify the issues above. In the current study, all the participants (18~70 years of age) would have the preoperative pathology of invasive breast cancer and positive fine-needle aspiration result in their clinical or ultrasonic suspicious axillary lymph node. 99mTc-labeled sulfur colloid was injected into the parenchyma under the ultrasound guidance 3 to 18 hours before surgery. Two syringes of 9.25 to 18.5MBq 99mTc-labeled sulfur colloid in 0.5 to 0.7mL volume were injected at the 6 and 12 o'clock positions 0.5 to 1.0 cm from areola (about 2.0~4.0 cm from the nipple). IM-SLNB was performed in all participants with IMSLN visualized on preoperative lymphoscintigraphy and/or detected by the intra-operative gamma probe. All hotspots in the internal mammary basin were harvested and intra-operative identification of the IM-SLN was based on gamma probe detection. The IM-SLN was sectioned along the long axis into two blocks and all blocks were tested by the frozen section and the touch imprint cytology intra-operatively. Those participants with positive intra-operative results received IMLN dissection. Finally, all the IM-SLN blocks and IM-NSLN dissected were assessed post-operatively by H&E and Cytokeratin 19 stained immunohistochemistry. The conclusion would be drawn through the results mentioned above.

Axillary lymph node status is a vital prognostic factors in breast cancer patients and provides crucial information for making treatment decisions.This projective observational study is planned to identify risk factors for axillary metastases in breast cancer patients with axillary ultrasound and to construct a nomogram to predict the risk of axillary metastases in these patients.

Blood samples from a total of 200 women in two cohorts will be collected and analyzed by TM-B1 assay, which is based on TBIA (Total Biochemical Infrared Analysis) to confirm the presence of cancer. These two cohorts will yield 75 healthy women with no pathological findings, 75 women diagnosed as having benign breast tumor and 50 women diagnosed as having breast cancer.

Purpose: Screening of large samples is to search the gene mutation of the breast cancer susceptibility gene (BRCA1 and BRCA2) in Chinese high risk group. To build the breast cancer BRCA1/2 mutation database of Chinese group. To build the hazard model of breast cancer BRCA1/2 mutation of Chinese group.

This study is an observational study to determine phenotype and genotype of CYP2D6 as predictors of z-endoxifen concentrations in plasma of outgoing patients treated with tamoxifen for at least 4 months

Prospective MR-imaging study : role of magnetic resonance (MR) and Diffusion weighted imaging (DWI) MR in staging and therapy assessment in breast cancer patients with bone metastases.

The major purpose of this study is to evaluate a laboratory developed test that measures multiple breast cancer-specific biomarker proteins in your blood samples. The biomarker results along with your personal medical profile will be evaluated to determine your risk for the presence of a malignancy in the breast as compared to your breast evaluation assessment conducted by your physician.
