Filter by:In this study the characteristics and alterations of the gut microbiome during chemotherapy for metastasized or irresectable CRC are studied, as well as the relation between the gut microbiome and the effects of chemotherapy.
The infrapyloric (No.206) and greater curvature (No.204) lymph node metastasis in adenocarcinoma located at hepatic flexure and right half of transverse colon has not been well discribed and analysed. The aim of this study is to assess the rate of this lymph node metastasis and to reveal its prognostic value for colon cancer located at hepatic flexure and right half of transverse colon. Meanwhile, we can evaluate the safety and feasibility of this extented lymphadenectomy in right hemi-colectomy.
Pain is a common symptom in patients nearing the end of life. Its prevalence varies between 30 and 75%. Nowadays, morphine is the most used molecule as first line treatment of moderate to severe pain. However, this molecule, considering its side effects, may contribute in part to the discomfort of these patients and may increase the pre-existing agitation or delirium. There is therefore a need to find new agents, other than morphine, for pain control at the end of life, without the limitations that the morphine molecule has. The author reviewed the literature on the role of dexmedetomidine in the treatment of refractory symptoms in palliative care, including pain. It is an agonist of the adrenergic alpha 2 receptor having a sedative, analgesic action and a morphine sparing effect demonstrated postoperatively. This study aims primarily at demonstrating that dexmedetomidine has a beneficial role in the treatment of pain in patients with metastatic cancer.
Pyrotinib is an oral tyrosine kinase inhibitor targeting both HER1, HER2 and HER4 receptors. This study is a single-arm, prospective, open label clinical study of pyrotinib plus vinorelbine as the therapy of brain metastases from HER2-positive metastatic breast cancer.
Clinical trial to assess the effectiveness of the supplement Colaren® associated with zoledronic acid 4mg/annually in the treatment of osteoporosis secondary, compared to standard treatment plus zoledronic acid 4mg/annually. The standard treatment will include 1gr of calcium/day and vitamin D supplement. In both cases, vitamin D levels will be determinated, which should remain at more than 30 ng/mL. Including men with osteoporosis secondary to HIV and men with osteoporosis secondary to any other cause (HIV negative). Vitamin D levels, bone densitometry and markers of metabolism, bone formation and bone resorption will be assessment. The all parameters above will be assessed basally (before the start of treatment), after starting the treatment, an assessment will be made at 12 weeks where vitamin D levels and bone markers will be measured. Meanwhile, at week 24 assess only vitamin D levels; and finally, at week 52 all parameters mentioned above will be measured.
The purpose of this study is to retrospectively collect and analyse the characteristics of breast cancer patients with bone metastasis, and compare the impact of intensive follow-up with standard post-operative surveillance on survival of Chinese breast cancer patients.
The presence of lymph node metastasis is an important factor in determining the appropriate treatment plan in patients with OSCC. However, detection of lymph node metastases by means of current imaging modalities is limited. 20-30% of patients with a clinically negative neck (cN0) harbour lymph node metastasis that were not detected during clinical diagnostic workup, which are referred to as occult lymph node metastasis. Therefore, patients with a risk of lymph node metastasis higher than 20% undergo a sentinel node procedure (SNP) or elective neck dissection (END), which means that a substantial part of patients is overtreated. There is need for an additional non-invasive diagnostic tool that can identify lymph node metastasis and thereby support the decision making for treatment of the neck. The main objective of this study is to evaluate if EGFR-positive cervical lymph node metastasis can be detected non-invasively with multispectral optoacoustic imaging using cetuximab-800CW as contrast agent in patients with oral squamous cell carcinoma.
Pancreatic Neuroendocrine Neoplasms (PanNEN) are a heterogeneous group of neoplasms that arise from the endocrine cells of the pancreatic gland. Non-functioning (NF-PanNEN) represents the most common forms and do not produce syndromes due to hormonal hypersecretion. Several prognostic factors have been demonstrated for NF-PanNEN. The presence of nodal metastasis and lymph node ratio are widely considered predictors of disease-free survival and even the number of positive nodes has been found to be associated with recurrence. In addition to traditional imaging exams, diagnostic work-up should include a Positron Emission Tomography/CT with 68Ga labeled somatostatin analogues, which have shown a high sensitivity and specificity while 18F-FDG PET can be associated for evaluating the possible presence of a high-grade component. Moreover, pancreatic endoscopic ultrasound (EUS) is usually part of the preoperative staging both for imaging details and cytological sampling. Therefore an accurate identification of nodal metastases preoperatively may have important implications for the extent of surgical resection and lymphadenectomy and even for a prognostic outcome. In this study the investigators will evaluate prospectively the accuracy of these diagnostic exams in detecting the lymph node status. Patients with sporadic NF-PanNEN who are candidates for surgical resection will undergo CE-CT scan, 68Ga DOTATOC (and eventually 18F-FDG) PET/MRI and EUS with FNA/B. Reference standard for defining the presence of nodal metastases is represented by pathological examination on the specimen.
It was difficult to obtain clinical benefits through traditional chemotherapy and radiotherapy for the patients who have recurrence or metastasis tumor even though they have received first-line chemotherapy or combined radiotherapy before, but failed.The aim of this study was to evaluate the safety and efficacy of apatinib, an anti-angiogenesis drug, in the treatment of patients with advanced esophageal squamous cell carcinoma who had recurrence or metastasis after radical resection
This is a multicenter, randomized open-label Phase 2 study to assess the safety, efficacy and pharmacokinetic (PK) of 2 dosing regimens of encorafenib + binimetinib combination in patients with BRAFV600-mutant melanoma with brain metastasis. Approximately 100 patients will be enrolled, including 9 patients in a Safety Lead-in of the high-dose treatment arm. After a Screening Period, treatment will be administered in 28-day cycles and will continue until disease progression, unacceptable toxicity, withdrawal of consent, start of subsequent anticancer therapy, death.
