NCT ID: NCT06148961 Not yet recruiting - Clinical trials for Excessive Gingival Display

Effect of Botox Before Modified Lip Repositioning Repositioning Only in Relapse of the Excessive Gingival Display Within One Year (Randomized Controlled Clinical Trial)

Start date: December 1, 2023
Phase: N/A
Study type: Interventional

The growing interest of patients in esthetic procedures, as well as the development of less invasive protocols in dentistry, has promoted the development of treatment plans that include stability, harmony, and function in orofacial rehabilitation. Poor esthetics interfere with an individual's personal, social, and professional relationships and is an individual consideration that varies according to the patient's age, time, region, and culture concerning what is considered beautiful. (Flores-Mir et al., 2004)

Prognostic Role of Inhibitor of Apoptosis Protein Overexpression on Recurrence Rate in Cervical Cancer

Start date: November 2023
Study type: Observational

Overexpression of inhibitors of apoptosis proteins (IAPs) in patients treated for locally advanced cervical cancer with exclusive radio-chemotherapy may have a prognostic role on the local recurrence rate at 24 months.

NCT ID: NCT06146296 Recruiting - Orthodontic Relapse Clinical Trials


Start date: November 1, 2023
Phase: Phase 2/Phase 3
Study type: Interventional

The aim of this study is to evaluate and compare the effect of locally injected and orally administered (systemic) Vitamin C on post-orthodontic treatment relapse

NCT ID: NCT06143644 Active, not recruiting - Colorectal Cancer Clinical Trials

Predictive Value of Postoperative Circulating Tumor DNA Monitoring for Colorectal Cancer Recurrence

Start date: January 15, 2022
Study type: Observational

This observational study aims to assess the predictive value of postoperative circulating tumor DNA (ctDNA) monitoring in evaluating the risk of recurrence in stage I-IV colorectal cancer patients. The study involves the collection of blood samples from patients who have undergone surgery for colorectal cancer. Sensitivity-enhanced molecular biology techniques are utilized to detect ctDNA in these samples. The correlation between ctDNA detection and the risk of recurrence is evaluated by analyzing patient follow-up data and clinical information. The findings of this study may contribute to the development of improved postoperative management strategies, such as identifying high-risk individuals and implementing additional treatment measures to reduce the risk of recurrence.

NCT ID: NCT06142929 Not yet recruiting - Dupuytren's Disease Clinical Trials

Micronerves in Dupuytren and the Impact of Its Dissection on Recurrence

Start date: January 1, 2024
Study type: Observational

Dupuytren disease (DD) is a highly prevalent disabling hand disease. Spontaneous fibrosis nodules and strands in the palms of the hand cause finger contractures in disturbing positions and movement restrictions. Finger movement can be restored by surgery (removing the fibrosis tissue), but recurrence is a major problem and this is difficult to treat. Through microfasciectomy, the presence of small nerve bundles (micronerves) were observed. These nerves are possibly related to the hand fascia, which is the origin of Dupuytren disease. These micornerves and their dissection could play a role in the recurrence of DD. This study will investigate the role of these micronerves in DD, the impact of its dissection on formation of neuromas and on recurrence. Also, the presence of nerve growth factor (NGF) will be evaluated. The purpose is to provide information on potential neuro-induced fibrosis.

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

Spatial Location of Breast Cancer Local Recurrence After Mastectomy

Start date: September 1, 2021
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: NCT06126276 Not yet recruiting - Clinical trials for Malignant Solid Neoplasm

Testing the Use of Neratinib or the Combination of Neratinib and Palbociclib Targeted Treatment for HER2+ Solid Tumors (A ComboMATCH Treatment Trial)

Start date: February 20, 2024
Phase: Phase 2
Study type: Interventional

This phase II ComboMATCH treatment trial compares the effect of neratinib to the combination of neratinib and palbociclib in treating patients with HER2 positive solid tumors. Neratinib and palbociclib are in a class of medications called kinase inhibitors. They work by blocking the action of an abnormal protein that signals cancer cells to multiply. This helps slow or stop the spread of tumor cells. Giving neratinib and palbociclib in combination may shrink or stabilize cancers that over-express a specific biomarker called HER2.

NCT ID: NCT06125483 Recruiting - Clinical trials for Hematopoietic Stem Cell Transplantation

TBI/Flu/Bu/Mel Combined With Secondary UCBT in Patients With Hematological Malignancies Who Relapsed After Allo-HSCT

Start date: November 1, 2023
Phase: N/A
Study type: Interventional

About 33% of patients with myeloid or lymphoid malignancies experience relapse with HLA loss after haplo-HSCT [6,7]. Due to the specificity of HLA-loss relapse, the 2019 European Society for Blood and Marrow Transplantation (EBMT) pointed out that for diagnosed HLA-loss patients, it is recommended to use different HLA-haploidentical donors, and lymphocyte infusions from the original donor cannot improve the prognosis. Clinical studies have found that second transplantation can achieve prolonged disease-free survival than chemotherapy for patients with HLA loss, and it may be an effective treatment strategy for these patients. However, due to the high standard of second hematopoietic stem cell transplantation (HSCT), not all patients can find suitable donors. Since the first successful application of umbilical cord blood transplantation (UCBT) by Gluckman et al. in France in 1988 for the treatment of Fanconi anemia [11], umbilical cord blood (UCB) has been widely used as a reliable source for HSCT in the treatment of hematological diseases. In 1998, Professor Yongping Song led the first successful UCBT in the treatment of leukemia, opening up the path of it in China. Compared with peripheral blood stem cell transplantation (PBST), UCBT has a higher engraftment rate. UCB contains more primitive and purer stem cells than bone marrow hematopoietic stem cells. UCBT can be performed with only 4 HLA matches, and the degree of rejection, the risk of disease relapse, and the incidence of chronic graft-versus-host disease (cGVHD) are all relatively low, greatly improving the survival of patients [14]. Although UCBT has been a potential treatment for second transplantation, the effective conditioning regimen is still under discussion. Improving the incidence of engraftment , the tolerance of conditioning, and reducing transplant-related mortality (TRM) are issues of great concern in second transplantation. A standard RIC regimen composed of fludarabine (200mg/m2) combined with cyclophosphamide (50mg/kg) and 2Gy or 3Gy total body irradiation (TBI) is the most common conditioning regimen used in UCBT [19]. Although the tolerance of this RIC is acceptable, the relapse rate after transplantation is relatively high, and the implantation failure rate is also high in high-risk populations. The inclusion of thiotepa (10mg/kg) combined with fludarabine, cyclophosphamide, and 4Gy TBI in an intensified version of the RIC regimen has improved the engraftment rate without increasing TRM [20]. In addition, studies have also confirmed that increasing the dose of TBI can improve engraftment in transplant recipients at high risk of UCBT failure [21]. The fludarabine/busulfan/melphalan (Flu/Bu/Mel) conditioning regimen was first used for salvaging UCBT in unresponsive hematological malignancies in 2016 and achieved good clinical outcomes [22]. Subsequently, several transplant centers in Japan adopted the Flu/Bu/Mel conditioning regimen for UCBT and confirmed that, compared with the Flu/Bu4 regimen, it not only improved overall survival (OS) but also reduced disease relapse rate without increasing TRM [23]. A recent multicenter retrospective study of UCBT in patients with acute myeloid leukemia in remission found that compared with the TBI/Cy conditioning regimen, the Flu/Bu/Mel conditioning regimen improved the engraftment rate and exerted the GVL effect, reducing NRM and improving OS [24]. Based on the above, TBI/Flu/Bu/Mel as a conditioning regimen for secondary UCBT in patients with hematological malignancies who relapsed after allo-HSCT is safe and feasible, and is expected to improve the prognosis of these patients. Therefore, based on existing clinical experience with research evidence, our center plans to conduct a clinical study of low-dose TBI and FBM as a conditioning regimen for secondary UCBT in patients with hematological malignancies who relapsed after allo-HSCT, observing the improvement in the cumulative incidence of engraftment, disease relapse, GVHD, and survival rate in patients who received this regimen.
