NCT07386444
This clinical trial studies whether breathing exercises for the muscles that help with breathing air in, inspiratory muscle training (IMT), works to improve breathing muscle strength, shortness of breath, and physical activity levels in women who are receiving chemotherapy for early-stage breast cancer (BC). Cancer and/or treatments for BC can directly result in muscle wasting that involves breathing muscles, skeletal muscles or heart muscles. Pain, weakness, shortness of breath, and side effects of cancer treatment may lead to lower physical activity levels. IMT involves breathing exercises using a small hand-held device. The device makes it a little harder to breathe in, which may help strengthen breathing muscles. IMT may be an effective way to improve breathing muscle strength, shortness of breath, and physical activity levels in women who are receiving chemotherapy for early-stage BC.
NCT02212860
Radiation therapy after surgery to remove breast cancer improves control of the breast cancer. Standard therapy after breast conservation surgery is five to six weeks of radiation to the entire breast. This clinical trial will evaluate the effectiveness of conformal radiation therapy delivered only to the area in the breast where the lumpectomy will be performed. This study will determine if radiation therapy delivered in this manner will prevent the cancer from coming back and eliminate the need for five to six weeks of radiation. Eligible participants will be randomized to one of two arms; Arm 1 which is comprised of one neoadjuvant radiation treatment, or Arm 2 which is comprised of three neoadjuvant radiation treatments. The study will also gather information about the safety and effects (good and bad) this radiation has, the immune priming effects of this radiation, and on patient satisfaction with the appearance of the breast.
NCT05417867
This pilot study seeks to understand how changes in the bacteria composition (microbiome) of the gut may be associated with the occurrence of fatigue and chemotherapy-induced nausea (CIN) in women undergoing chemotherapy for early stage breast cancer. Patients undergoing chemotherapy may experience fatigue or nausea as a result of their treatment. Known risk factors for fatigue and CIN do not explain the differences in fatigue and CIN occurrence between patients, but changes in the functions of the gut microbiome may be related to the occurrence of fatigue and CIN. This study collects stool samples from breast cancer patients before and after chemotherapy to evaluate how changes in the microbiome may be associated with fatigue and CIN.
NCT02876640
This phase 1b trial studies the biologic effect of 9cUAB30 on early stage breast cancer. 9cUAB30 is a retinoid X receptor (RXR)-selective retinoid that acts in a tissue selective manner with the goal of minimizing side effects, a necessary feature of agents under development for cancer prevention.
NCT02095743
Adjuvant chemotherapy is frequently proposed to patients presenting early breast cancer, in case of high risk of recurrence (large tumors, node involvement, high grade…). Due to its toxicity toward veins, chemotherapy must be administered through a central venous device. Today, one can use either an implanted port or a PICC line (Peripherally Inserted Central Catheter). A PICC line is easier to implant and to explant, but has to be flushed every week and may impact daily life (no swimming, some clothes may not fit). On the other hand, a port is subcutaneous and lets patients lead a normal life, but its implant and explant require a cutaneous incision with possible complications (bleeding, pain, infection). For both venous devices, complications such as thrombosis or infection may happen. Published data comparing the two devices are heterogeneous and do not often distinguish patients treated for different diseases at various stages. Empirically in daily practice, for long term use (\>6 months) a port is usually preferred, whereas for short-term treatments (\<6 weeks) a PICC line is used. In the case of Her2 negative early breast cancer, adjuvant chemotherapy usually lasts 4 to 5 months. There is no scientific evidence for preferring one device to the other for these patients. The aim of this study is to prospectively compare the patients' satisfaction and tolerance of each of the two devices.
