NCT ID: NCT06176339 Active, not recruiting - Clinical trials for Breast Cancer Female

Assessing the Clinical Utility of Adding Pentoxifylline to Neoadjuvant Chemotherapy Protocols in Breast Cancer Patients"

Start date: December 15, 2023
Phase: Phase 2
Study type: Interventional

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.

Using Color Doppler US Artifact to Identify Tumor Markers

Start date: August 1, 2023
Phase:
Study type: Observational [Patient Registry]

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.

NCT ID: NCT06130111 Active, not recruiting - Breast Cancer Clinical Trials

Spatial Location of Breast Cancer Local Recurrence After Mastectomy

Secret
Start date: September 1, 2021
Phase:
Study type: Observational

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).

NCT ID: NCT06086340 Active, not recruiting - Breast Cancer Clinical Trials

Study to Compare Overall Survival in Medicare Patients With Metastatic Breast Cancer Treated With a Medicine Called Palbociclib in Combination With Aromatase Inhibitor and Aromatase Inhibitor by Itself.

Start date: September 29, 2023
Phase:
Study type: Observational

A retrospective study of de-identified (to preserve patient privacy) patient information from the SEER-Medicare Database to compare overall survival of first line palbociclib + aromatase inhibitor (AI) therapy versus AI therapy alone treatment in women or men aged 65 and older with newly diagnosed hormone receptor positive/human epidermal growth factor receptor 2 negative (HR+/HER2-) metastatic breast cancer (MBC) in the United States

NCT ID: NCT06015100 Active, not recruiting - Breast Cancer Clinical Trials

Efficacy and Safety of Inetetamab Plus Pyrotiniband and Capecitabine in HER2-positive Metastatic Breast Cancer Patients With or Without Brain Metastasis

Start date: February 20, 2021
Phase: N/A
Study type: Interventional

This study intends to include HER2-positive metastatic breast cancer patients (with or without brain metastasis) who have become resistant to previous treatment with trastuzumab. It will use pertuzumab in combination with pyrotinib and capecitabine to observe efficacy and safety. The choice of capecitabine as the chemotherapy drug is mainly based on the following reasons: ① it has been less commonly used as neoadjuvant treatment, making it less prone to cross-resistance; ② its oral formulation is convenient for administration, making it more acceptable to patients; ③ previous studies have shown good efficacy when combined with pyrotinib; ④ previous research in breast cancer patients with brain metastasis has also demonstrated certain effectiveness. It is hoped that through this study, preliminary evidence can be provided for the dual-target treatment of original Chinese drugs, as well as the treatment of HER2+ MBC after resistance to trastuzumab, and the addition of new data for patients with brain metastasis.

NCT ID: NCT06003114 Active, not recruiting - Breast Cancer Clinical Trials

A Study to Understand the Use of Palbociclib in Canadian Patients With Breast Cancer That Has Spread to Other Organs

Start date: October 6, 2023
Phase:
Study type: Observational

The purpose of this real-world study is to understand the use of palbociclib as first treatment for Hormone receptor positive (HR+) and Human epidermal growth factor receptor 2 negative (HER2-) metastatic breast cancer in Canada (PALCAN). The real-world study is not a research study. It involves real patients who receive medicines prescribed by their doctors in the real world. Metastatic breast cancer is the type which has spread from breast to other organs. HR positive stands for Hormone-receptor cells that have a protein on their surface that binds to one of 2 types of hormones. They are estrogen or progesterone. Both these hormones help cancer cells grow. HER2 negative describes cells that have a small amount or none of a protein called HER2 on their surface. In normal cells, HER2 helps control cell growth. Cancer cells that are HER2 negative may grow more slowly and are less likely to come back or spread to other parts of the body. This study will mainly measure: - duration of treatment (from start of treatment till end of treatment) among a group of patients taking palbociclib (Ibrance) in combination with hormone therapy as first line treatment for HR+ HER2- metastatic breast cancer.
