Active clinical trials for "Carcinoma"

A medical review chart study in Japan to describe the treatment patterns and outcomes of patients with kidney cancer that is unable to be removed by surgery or that has spread. The clinical data is to be abstracted using electronic data capture (eDC) from patient medical records in Japan.

A multi-centre randomized non-inferiority trial investigating the (cost-)effectiveness of Optical Coherence Tomography (OCT) versus regular punch biopsy in the diagnosis and subtyping of Basal Cell Carcinoma (BCC).

This study is conducted to evaluate dynamic contrast-enhanced MRI to quantify the efficacy of trans-arterial chemoembolization by comparing imaging results before and after treatment for at least one hepatic tumor and to look at blow flow curves of the free-breathing MRI before treatment.

Patients with ductal carcinoma in situ (DCIS) treated with available therapies have experienced excellent outcomes and very low mortality rates due to the disease's non-invasive nature. However, considerable debate exists as to how the DCIS lesion should be treated. As a result, determining strategies to manage DCIS has been identified as a research priority. The role of sentinel lymph node biopsy (SLNB) for DCIS management is controversial in general and needs further scrutiny. Our study addresses this evidence gap as the investigators propose a retrospective cohort study to investigate the outcome of SLNB among DCIS patients. Specifically, the investigators will compare the outcomes, including survival outcomes and treatment side effects, among women older than 67 years of age with DCIS receiving SLNB vs. not receiving SLNB within 6 months of DCIS diagnosis. The investigators have two primary aims in this study: Aim 1: the investigators select our study sample using SEER-Medicare database. The investigators will determine associations between SLNB and acute/subacute side effects, including lymphedema, pain, and limitation of movement of upper extremity from the first breast conserving surgery to 9 months post-diagnosis. Aim 2: the investigators will determine associations between SLNB and long-term outcomes, including breast cancer specific mortality, ipsilateral invasive breast cancer diagnosis, subsequent mastectomy as treated recurrence, and lasting side effects, from >9 months post-diagnosis to death or the end of this study period. Given the nature of our observational study design, the investigators will apply standard multivariate analyses and propensity score methodology to reduce the influence from confounders. The investigators will control for patient demographics, comorbidities, functional status, tumor characteristics, and prior healthcare utilization. Using distance to the nearest provider that uses SLNB for DCIS or surgeon's tendency in using SLNB for stage I/II breast cancer, the investigators also plan to conduct instrument variable analyses if necessary. Stratifying patients by key DCIS characteristics (including grade, comedonecrosis, and tumor size) and their predicted life expectancy (given their age and comorbidities), the investigators also hope to identify patient subgroups who may safely forgo SLNB. The study would provide evidence on the efficacy and safety outcome of SLNB for DCIS management.

The clinical outcome of advanced / metastatic renal cell carcinoma has been changed since targeted therapy being widely applied. This study will retrospectively analyse the clinical outcome of advanced renal cell carcinoma captured in Taiwan National Health Insurance Research Database.

The purpose of this study was to explore the correlation between postoperative recovery of liver function and gut microbiota in patients with hepatocellular carcinoma (HCC). Liver resection patients were divided into the recovery group and the recovery delay group according to the recovery level of liver function on the fifth day after the operation. Benign liver disease was used as a control. Statistical analysis was performed to compare the differences in gut microbiota between the three groups. Then, fecal microbiota transplantation was performed in a mouse hepatectomy model. Through this study, the investigators hope to understand the relationship between gut microbiota and postoperative recovery of liver function in patients with hepatocellular carcinoma, so as to provide a new therapeutic direction for patients in the aspect of perioperative liver function recovery.

The surgical device used to perform PIPAC procedure is commercialized by a single manufacturer under a monopoly regimen, and a formal training (economically supported by the manufacturer) is mandatory for surgeons who want to buy the device.Relations with the company and solutions to extend training require specific analysis from an ethical point of view. Based on the growing number of published papers from a growing number of international centers, the controlled training model is not limiting, and it is a successful model of development of this breakthrough innovation. But with the major involvement of the industry and the control of training, the different levels of interest could induce ethical questions.

Background. Peritoneal carcinomatosis is a frequent and deadly localization of gastric cancer. Available imaging techniques have a low accuracy in detecting small peritoneal nodules, and direct laparoscopic visualization may fail too. A more accurate staging technique would be advantageous for individualization of therapeutic path. Indocyanine Green (ICG) fluorescence imaging has been reported as a tool for visualizing small peritoneal seedings due to the "enhanced permeability and retention" (EPR) effect of cancer nodules. Aim. To explore the feasibility and effectiveness of fluorescence-enhanced peritoneal carcinomatosis detection in patients with gastric cancer undergoing staging laparoscopy. Methods. This prospective, multicentric, single arm study will include patients with gastric cancer, without a radiological suspicion of peritoneal carcinomatosis, undergoing staging laparoscopy. An intravenous injection of ICG is given at different dosage and at different timepoints before the intervention. During the staging laparoscopy, the abdominal cavity exploration is performed using standard white-light, and subsequently using fluorescence imaging. Suspicious nodules are harvested, until a maximum of 5 per patient, and sent for definitive histological examination. Peritoneal washing is also harvested for cytologic assessment in all cases. The eventual benefit of fluorescence imaging in terms of additional peritoneal lesions that were not detected during standard white-light imaging is evaluated. Discussion. This study will establish if fluorescence imaging increases sensitivity and/or specificity of staging laparoscopy in detecting peritoneal carcinomatosis from gastric cancer. Improved accuracy may translate in better care path selection.

To understand the epidemiology, treatment patterns and outcomes of patients with metastatic Renal Cell Carcinoma (mRCC). Data from mRCC patients who received cabozantinib versus non-cabozantinib Tyrosine Kinase Inhibitor (TKI) (a type of targeted cancer drug) immediately after Check Point Inhibitor (CPI) treatment (a type of immunotherapy that blocks proteins that stop the immune system from attacking the cancer cells) in US community oncology practices will be analyzed.

This study utilizes a new method to explore compare the overall survival (OS) and cancer-specific survival (CSS) in patients aged 18-45 years with stage I-II HCC who underwent different types of surgery. The SEER database, which is one of the most comprehensive and authoritative databases concerning cancer, was used to estimate the survival benefit of patients who underwent local tumor destruction (LTD), wedge or segmental resection (WSR), lobectomy resection (LR), liver transplantation (LT), or non-surgery. This study discovered surgery offered a survival benefit compared with non-surgery for young patients with stage I-II HCC. Furtherly, LT is associated with superior survival than WSR, LR and LTD in those patients. Our results facilitate the selection of surgical strategies.
