Paravertebral block (PVB) has been shown to provide excellent analgesia for major breast surgeries resulting in reduced narcotic consumption, reduced nausea, improved quality of recovery, reduced chronic pain and possibly reduced metastasis with breast cancer. Traditionally, PVB is done by multiple injections below T1-T5 transverse processes. With multiple injections, the risk is increased for a pleural, an intraneural, and/or an intravascular injection. Recently, ultrasonography is being used to facilitate PVB. The use of ultrasound imaging enables real-time needle visualization during the procedure. This may improve efficacy and reduce the chances of complication like pneumothorax. Currently, there are no data comparing ultrasound-guided single injection technique with multiple injections technique with regards to extent of spread for PVB. Our objective is to investigate the extent of dermatomal spread of PVB when equal volumes of local anesthetic are injected at one versus five paravertebral sites for patients undergoing major breast surgery. In addition, the investigators wish to compare the performance time and duration of analgesia. Methodology: After local REB approval, 72 patients undergoing a unilateral mastectomy with or without axillary node dissection will be randomized to receive either single or multiple injections PVB. The PVB will be performed in prone position under real-time ultrasound guidance using a para-sagittal approach.The patients in single injection group will receive single injection PVB at T3-T4 level with 25 ml of 0.5% ropivacaine and four subcutaneous sham injections. Patients in the multiple injection group will receive five injections of PVB from T1 to T5 level. 5 ml of 0.5% ropivacaine will be injected at each level. Pleural drift will be used as a sign of correct needle tip location and local anaesthetic spread. The pinprick method will be used to assess the extent of dermatomal blockade, 20 minutes following the completion of procedure. All patients will receive a standardized general anesthesia for the surgery. Any adverse events including pneumothorax, epidural spread, LA toxicity/seizure, total spinal, will be recorded.
Adjuvant endocrine hormonal therapy (EHT) is highly effective and appropriate for nearly all breast cancer patients with hormone receptor-positive tumors, which represent 75% of all breast cancer diagnoses. Long-term use of EHT reduces cancer recurrence rates and cuts the risk of death nearly in half during the second decade after diagnosis, research shows. Despite the proven benefits, about 33% of women who are prescribed EHT do not take their medication as prescribed (less than 80% take their daily dosage) and are thus at higher risk of recurrence and death. This educational randomized controlled study will develop and pilot-test a bilingual, culturally tailored, personalized, interactive mobile application (app) in combination with patient navigation to promote and improve adherence to endocrine hormonal therapy (EHT) among breast cancer patients.
Breast cancer is a major public health problem. In France, it is the leading cause of cancer death in women. According to the National Cancer Institute (INCA), approximately 49,000 new cases were diagnosed in 2012 in France. It is an heterogeneous disease, comprising a plurality of entities whose clinical behavior, biological and prognosis differ. Amongst these entities, the breast cancer triple negative (TN) is defined by the absence of expression of estrogen receptor and progesterone and the absence of overexpression of HER2 oncoprotein. It represents about 15% of breast cancers and occurs more frequently in young women. This is a very proliferative tumor phenotype with metastatic potential. Because of its genomic heterogeneity and lack of recurrent identified molecular target, no targeted therapy has today shown benefit in terms of survival compared to conventional cytotoxic chemotherapy, which partly explains the very poor prognosis of this tumor phenotype. The positron emission tomography (PET) with 18Fluoro-deoxy-glucose (FDG) is a molecular imaging test that can identify from the first or second neoadjuvant chemotherapy treatment non-responder patients to treatment with low probability of pathologic complete response (pCR) after neoadjuvant chemotherapy. For this two FDG-PET examinations should be performed; a) a pretreatment PET b) a control PET after one or two treatments. The objective of this pilot, single-center, prospective study is a preliminary identification of recurrent genomic alterations among triple-negative tumors with early chemoresistance, identified by PET in the first cycle of neoadjuvant therapy.
Studies have shown that on-going pain following breast surgery is common and may limit the ability to participate in physical activity, cause tiredness, difficulty in daily chores/activities as well as other problems. This study is evaluating whether participating in a 12-week Qigong program (pronounced chee kung), an exercise program that involves gentle movements combined with breathing/relaxation techniques, also known as mind-body exercise, leads to improvement of pain, physical function, and quality of life among breast cancer survivors that have significant pain following surgery.
This study will evaluate the efficacy and safety of treatment with oral capecitabine or intravenous (IV) 5-fluorouracil (5-FU), in combination with epirubicin and cyclophosphamide, prior to surgery in participants with breast cancer. The participants will receive 4 cycles of neoadjuvant Capecitabine + Epirubicin + Cyclophosphamide (CEX) or 5-FU + Epirubicin + Cyclophosphamide (FEC 100) chemotherapy during first treatment period (Period 1, Days 1-85). After 4-6 weeks of the fourth cycle of neoadjuvant chemotherapy (Day 120 +/- 7 days), breast surgery with regional lymph node dissection will be performed, followed within a maximum of 6 weeks by the second treatment period (Period 2, Days 1 to 85) when participants in both study arms will receive 4 cycles of adjuvant docetaxel 100 milligrams per meter square (mg/m^2) by IV infusion on Day 1 of each 21-day cycle. Upon completion of the second treatment period, participants will enter the post-treatment follow-up period which will last for 5 years from the initial date of participant randomization. During this period participants will be evaluated once a year on the anniversary date of randomization.
Breast cancer patients often suffer from long-term physical symptoms of weakness. In this study, investigators propose to compare how two different low intensity physical exercise training programs can improve handgrip strength for breast cancer patients with symptoms of weakness. Using brain imaging, the study will also investigate changes in brain structure, and muscle activity associated with handgrip.
