The main goal of this study is to assess the impact of supervised intense physical activity (IPA) on outcomes of neoadjuvant chemotherapy in young women with breast cancer (YWBC). In this project standard neoadjuvant chemotherapy will be used concordant with summary of product characteristics (SPC). However during treatment (including days of chemotherapy application) an additional modifier of therapy will be carried out in the form of intense physical activity. This strategy is not recognized in SPC. This project aims to improve the results of breast cancer treatment in young women. According to available data, nowadays this subset of breast cancer patients has worse therapy results in comparison to older women. This is partially because of the different tumor characteristics; young women are more likely to present with human epithelial growth factor receptor 2 (HER2) receptor overexpression or with triple negative breast cancer. In the treatment of YWBC, preoperative chemotherapy is most often the first step. This enables the opportunity to assess the effectiveness of additional interventions in a mode it was never tested before. It is believed that physical activity improves the results of breast cancer treatment, however there are only few reports describing its benefit and role in terms of preoperative chemotherapy. In the current project, the investigators planned to introduce supervised increased physical activity concurrently with neoadjuvant treatment in YWBC at early stage of disease. The main goal of the study is to assess the effect of physical activity on preoperative chemotherapy outcomes. The change of tumor size after neoadjuvant chemotherapy, as well as the impact on Quality of Life (QoL) and Patients' Reported Outcome (PRO) in described above treatment modality. Secondary endpoints are the following: the pathologic Complete Response (pCR), disease free survival after 3 years (3-yr DFS), overall survival (OS), cardiotoxicity of treatment, the effect of physical activity on tumor microenvironment and Ki67 as well as the impact of increased physical activity on further patients' lifestyle changes.
Foreign data show that: 1807 tumor patients were followed up for 7 years, 33% of them died of heart disease and 51% of them died of the tumor itself. In China, the number of cancer patients undergoing chemotherapy is increasing rapidly every year. How to protect the heart of chemotherapy patients from the damage of chemotherapy drugs (especially anthracyclines) is a problem that clinicians must face.In order to further confirm the clinical efficacy and value of saffron total glycosides tablets in the protection of central function of breast cancer neoadjuvant patients with anthracycline based chemotherapy scheme, the project plans to follow up and observe the research of saffron total glycosides on the protection of cardiac function of breast cancer neoadjuvant patients with chemotherapy based on cardiac color ultrasound combined with myocardial zymography, and randomly group to confirm the effectiveness of saffron total glycosides tablets on cardiac protection, Based on the clinical observation and research on the effect of traditional Chinese medicine on the cardiotoxicity of anthracycline drugs, confirm its efficacy, explore the mechanism of cardiac protection, and explore the drug use method of synergism and toxicity reduction of anthracycline drugs in combination with this active ingredient.
This clinical trial is a randomized controlled trial that aims to assess the usefulness of adding pentoxifylline to the neoadjuvant chemotherapy treatment protocol of doxorubicin/cyclophosphamide for breast cancer patients to decrease the incidence of developing oral mucositis, downgrade the mucositis symptoms, alleviate the associated pain using the visual analogue scale, and enhance the quality of patient life using the EQ-5D-3L questionnaire. The participant will administer Pentoxifylline oral tablets three times per day along with the treatment protocol, starting from the first doxorubicin/cyclophosphamide cycle till the end of the fourth cycle. The researchers will compare the mucositis incidence and grade in the presence or absence of oral pentoxifylline.
This prospective randomized study investigated the reproducibility of breast shape, radiation dose irradiated to the lungs, heart, dose distribution, patient satisfaction, and treatment toxicity when wearing and not wearing a bra during radiotherapy for patients with breast cancer.
Breast cancer, a leading cause of cancer-related mortality in women worldwide, has spurred the investigation of novel therapeutic approaches. Pentoxifylline (PTX), a synthetic methylxanthine derivative, has shown promise in preclinical studies when combined with conventional anticancer drugs. This study aims to assess PTX's impact when added to neoadjuvant chemotherapy protocols in breast cancer patients, with the goal of improving treatment outcomes and reducing associated toxicities.
Before neoadjuvant chemotherapy (NACT) in cases of locally advanced breast cancer, malignant masses in the breast and biopsy-proven tumor involvement axillary lymph nodes are marked with metallic markers. The primary objective of this marking is to establish the precise localization of the tumor which response to NACT partial or completely. However, selecting the marker with ultrasound (US) proves challenging in many instances. Research studies indicate that patients with occult markers are observed at a frequency of 24%. Some studies propose that the twinkling artifact serves as a reliable method for accurately indicating the localization of certain tumor markers. This artifact is deemed particularly helpful for lesions situated in the axilla or posterior of the breast, which may not be visible with US and are undetectable with mammography. In the context of Color Doppler examination, the investigators have noted the presence of another color Doppler artifact which can aid in determining marker localization. When the pulse repetition frequency (PRF) is reduced and the color gain is increased, color noise, termed as color confusion or blooming artifact/effect, is observed within the color steer. While this color confusion tends to mask healthy tissues, it has been observed that the tumor marker remains unaffected by the blooming effect. Consequently, this artifact serves to distinctly reveal the borders and localization of the tumor marker. In some studies, it has been stated that the twinkling artifact, which is a color Doppler artifact and whose mechanism is not fully understood, is a reliable method to accurately indicate the localization of some tumor markers. It has been reported that this artifact will be very helpful, especially in lesions located in the axilla or posterior of the breast, which cannot be seen with US and cannot be detected with mammography . In Color Doppler examination, we saw that another color Doppler artifact, such as the twinkling artifact, could also be helpful in determining marker localization. When the PRF is reduced and the color gain is increased, color noise, which is selected as color confusion and can be called blooming artifact or blooming effect-like, is observed in all structures within the color steer. While healthy tissues are masked by this color confusion, the tumor marker is protected from the blooming effect. Thus, with this artifact, tumor marker borders and localization are clearly revealed.
Rationale:To improve the definition of the target volume for radiotherapy of the chestwall after different types of mastectomy, the exact localization of regions at risk for a local recurrence should be known. However, there are currently insufficient data in literature showing where local recurrences occur after different types of mastectomy. Objective: The primary objective of the proposed study is to determine whether the spatial, location of a breast cancer recurrence after mastectomy, differs for different types of mastectomy. Study design: Retrospective study evaluating spatial location and site of recurrences after mastectomy. Study population: The investigators aim to include all breast cancer patients treated with mastectomy in the Netherlands between 2003- 2008, and known to have experienced a local recurrence as the first site of failure. Primary endpoint: Spatial location of local recurrence (e.g., primary tumour bed, scar, skin, subcutaneous, nipple, areola, pectoral muscles).
