Active clinical trials for "Neoplasms"

At present, surgical resection is still the main treatment for the potential cure of rectal cancer. Total mesorectal excision (TME) is the gold standard. The traditional laparoscopic or open surgery for some special patients is really difficult, especially for male, prostate hypertrophy, obesity, low tumor and pelvic stenosis patients to expose the gap around the mesorectum and separate to the pelvic floor. While transanal total mesorectal excision (TaTME) approach could be more directly separate the low mesorectum and relatively simple to complete distal rectal transection, which would bring some considerable advantages. Although active learning from abroad, laparoscopic assisted TaTME surgery is now in its infancy in China. It is urgent for clinical studies to obtain the results in China. This multicenter, observational study will help to encourage research in this field and to obtain data on the safety and efficacy of this procedure in Chinese patients with rectal cancer.

Background and objective The introduction of a proteasome inhibitor bortezomib has significantly improved response rates and overall survival in patients with multiple myeloma (MM), and it has soon become the cornerstone of treatment in both newly diagnosed and relapsed/refractory settings. However, the incidence of peripheral neuropathy related to bortezomib (BiPN) is unignorable and which becomes an obstacle during treatment with bortezomib, either alone or in combination. Until now, there are no consistent findings regarding the risk factors that may cause BiPN. There is either lack of large scale study of BiPN in Taiwan. This study aims to clarify risk factors of BiPN using retrospective analysis in a large cohort with longer observation period as well as the relations between BiPN and gene polymorphisms, and to compare different routes in the incidence of BiPN. Methods This is a retrospective cohort study with a sample size of about 400 MM patients treated ever with at least one full cycle of bortezomib in the institution. All the patients enrolled need to be adults (≧20 years ) with measurable M-component in either blood or urine. The investigators will perform a retrospective chart review to collect clinical data, including anti-MM and concomitant medications, to evaluate the incidence and severity of BiPN in this cohort, as well as any meaningful risk factors contributed to BiPN. The investigators also plan to perform genotyping for the possible genetic factors associated with development of BiPN. Expected contributions The successful collaboration between clinical hematologist-oncologist and biopharmaceutical researcher would result in the concrete evidence of efficacy and safety of bortezomib in Taiwanese patients with MM. The findings in this large cohort study will unveil the risk factors of BiPN, including the administration routes and ethnicity. As results, the investigators would be able to provide the precision medicine-based bortezomib treatment strategy to MM patients in Taiwan.

Uterine fibroids are benign uterine masses that can be removed through a surgical procedure called a myomectomy. Myomectomy is often associated with a significant amount of blood loss for the patient. The large volume of blood lost can increase post-operative complications and lead patients to require blood replacement (blood transfusion). To reduce the amount of blood lost during the surgical procedure and the need for blood transfusions, interventions such as medications and surgical techniques have been used. While evidence in the literature exists for these techniques, there is no standardized approach to this problem in clinical practice. The objective of this study is to create a novel intra-operative blood conservation pathway, using a modified Delphi expert consensus approach, to decrease the amount of blood lost during myomectomy. The current study is expected to benefit patients undergoing myomectomy through an improved surgical experience, reduction in blood transfusion rates, and reduction in associated complications.

Chronic Myelomonocytic Leukemia (CMML) is the most frequent of myelodysplastic/myeloproliferative syndromes, as defined by the WHO classification of myeloid malignancies. The median age at diagnosis is around 70 years with a strong male predominance. CMML is a clonal disease of the bone marrow hematopoietic stem cell mainly characterized by persistent monocytosis (>1x109/L) and the presence of immature dysplastic granulocytes in the peripheral blood of CMML patients. Allogeneic stem cell transplantation (ASCT) remains the only curative option in CMML. However, CMML patients are rarely eligible for this kind of therapy, mainly due to their advanced age. The gold standard treatment of CMML thus remains hydroxyurea, which is usually initiated when the disease becomes proliferative, and demethylating agents, which could be efficient in the most aggressive forms of CMML. Nevertheless, the pathogenesis of CMML remains poorly understood and new therapies are urgently needed for patients in treatment failure. In recent years, a large numbers of gene mutations have been discovered in CMML, none of which are specific of this entity, as they can be encountered with different frequencies in other myeloid neoplasms. These mutated genes encode signaling molecules (NRAS, KRAS, CBL, JAK2, FLT3 and several members of the Notch pathway), epigenetic regulators (TET2, ASXL1, EZH2, IDH1, IDH2,.) and splicing factors (SF3B1, SRSF2, ZRSF2). Mutations in the transcription regulators RUNX1, NPM1 and TP53 have also been reported in CMML. However, the role of these mutations in leukemogenesis is still unclear. CMML is also characterized by defects in monocyte to macrophage differentiation. These defects in monocyte differentiation can be attributed to the presence of immature dysplastic granulocytes that secrete high levels of alpha-defensins HNP1-3 that antagonize the purinergic receptor P2RY6 in CMML patients. These CD14-/CD15+/CD24+ immature granulocytes that belong to the same clone than the leukemic monocytes seem to have immunosuppressive properties ressembling those of the myeloid-derived suppressor cells (MDCS) described in solid tumours. Whether these immature granulocytes contribute to autoimmune manifestations or immunoescape and progression of CMML is a conendrum and remains to be determined. In this context, the proposed project aims at identifying news insights into the pathophysiology of CMML through a better definition of the phenotype and function of monocytes and immature granulocytes that characterize this pathology.

This study is designed to evaluate the predicted potential of quantitative T cell repertoire (TCR) of T cell receptor chains using next-generation sequencing (NGS) in the treatment of the anti-programmed death-ligand 1 (PD-L1) antibody atezolizumab in participants with locally advanced or metastatic NSCLC who have progressed during or following a platinum-containing regimen. Treatment may continue until disease progression or unacceptable toxicity.

The global cancer burden is estimated to have risen to 18.1 million new cases in 2018 (WHO), with a trend of ongoing growth. This very frequent illness exerts tremendous physical, emotional and financial strain on individuals, families, communities and health systems. Malnutrition (under- or over-nutrition) is highly prevalent in cancer patients receiving chemotherapy and is an important predictor of morbidity, mortality, treatment response and toxicity. Alterations in taste and smell are frequently reported as side effect of chemotherapy and may contribute strongly to malnutrition and to a worsen quality of life and wellbeing social, emotional, and role functioning. There are evidences that chemotherapy influences food liking and appetite with implications for food behaviours, including food enjoyment, food preference and dietary intake. A linkage between alterations in taste and /or smell and food behaviours has been reported by some studies but not all, suggesting that there is a need for more research using common standardised methodologies and larger sample size to gain a further insight into this topic.
