Liver Neoplasms

Worldwide, primary liver cancer is the 3rd most common cause of cancer-related death, accounting for 6% of cancer diagnoses. In the UK, the number of cases reported has more than trebled since the 1970's, with 5550 new cases in 2014 (CRUK statistics 2014). Liver transplant or surgery are the main forms of treatment offered but only less than 20% of patients can tolerate these treatments. There is a need for non-surgical therapies that would improve these patients' chances of survival. Radiotherapy has been shown to increase the likelihood of liver cancer cure. To deliver radiotherapy safely to the patient, the radiation must be delivered to the liver cancer only, avoiding normal liver tissues and other surrounding normal tissues. Because the liver moves during breathing, a liver cancer will also move during radiotherapy. To accurately target the cancer the patient can be asked to hold their breath during treatment to stop the motion. Or motion of the cancer can be monitored and the radiation beam can be moved to follow its motion. The investigators are investigating new methods to either: (a) ensure that when the patient repeats their breath hold the cancer is in the same position each time, or (b) measure the motion of the liver cancer whilst the patient breathes freely. It is not clear which is the best method and therefore are investigating both approaches. Ultrasound is a non-invasive and real-time imaging method that can easily be used to image the liver and may be able to perform both of these tasks. In this study the investigators will test ultrasound equipment, which has been specifically designed to guide radiotherapy. 26 healthy volunteers will be recruited to help evaluate the accuracy of ultrasound to measure the position of the liver in breath hold and in free breathing.

A Model for Predicting the Efficacy of Conversion Therapy for Patients With Colorectal Cancer Liver...

Colorectal Cancer With Liver Metastases

In this study, the investigators establish a model for predicting the efficacy of conversion therapy for the patients with unresectable liver metastases of colorectal cancer based on the detection of 5-hydroxymethylcytosine (5-hmC) in training group and validate the effectiveness of the model using a validation group.

Long-term Outcomes After Breast Cancer Liver Metastasis Surgery: an European, Retrospective, Snapshot...

Breast CancerLiver Metastases1 more

Breast cancer ranks as the top leading malignant tumors among females, and also accounts for the most common cause of tumor related mortality in females worldwide. Approximately, 20-30% of breast cancer cases develop metastasis, while 50% of patients will suffer from breast cancer liver metastasis. The proper indication for surgical treatment of breast cancer liver metastasis is still a matter of discussion. Surgery is becoming more practical and effective than conservative treatment in improving the outcomes of patients with breast cancer liver metastasis and liver metastasis surgery is included in an onco- surgical strategy.

Extracolonic Findings on Computed Tomography (CT) Colonography

Solitary Pulmonary NodulesMultiple Pulmonary Nodules8 more

The ACRIN 7151 trial will use medical records abstraction data from participants with extracolonic findings (ECFs) reported from the ACRIN 6664 National CT Colonography Trial to: 1) measure incidence of diagnostic imaging, hospitalization, and interventional procedures associated with ECFs reported on computed tomography colonography (CTC), delineated by type of ECF; 2) determine potential predictors of follow-up diagnostic imaging, hospitalization, and interventional procedures, delineated by type of ECF; and 3) evaluate the clinical/pathologic diagnoses associated with indeterminate but potentially significant ECFs. These data can be used to incorporate ECFs into existing models on the cost-effectiveness of CTC in colorectal cancer screening and can potentially be used to develop guidelines for the reporting and management of ECFs.

Drug Monitoring of Sorafenib in Patients With Advanced Hepatocellular Carcinoma

Hepatocellular Cancer

Sorafenib improves overall survival and progression free survival in advanced hepatocellular carcinoma. Wide interindividual pharmacokinetic variability was observed. Data from early phase trials in solid tumours showed trough sorafenib levels were associated with incidence of skin rash and hypertension. Rash, hypertension and higher trough levels were moderately predictive of progression free survival.The trough level of sorafenib may be predictive of survival and response in patients treated with sorafenib for advanced hepatocellular carcinoma.

A Study to See if we Can Predict How Your Liver Tumor or Liver Metastases Will Respond to Trans-Arterial...

Liver CancerLiver Metastases

The purpose of this study is to see if certain genes the tumor can help predict how the tumor will respond to Trans-Arterial Embolization (TAE). A gene is the basic physical and functional unit of heredity. Genes are made up of DNA; DNA (deoxyribonucleic acid) is the hereditary material in humans. Identifying a gene that can predict how liver tumors will respond to TAE will also help to determine if adjuvant therapy will be needed after TAE.

Gut Microbiota in People With Hepatocellular Carcinoma (HCC)

Hepatocellular CarcinomaLiver Cancer2 more

Background: There are about 100 trillion microbial cells in a person s gut. This is called the human gut microbiota. When this is disrupted, it can lead to many diseases. Studies show that the gut microbiota in people with cancer is different than that found in healthy people. Researchers want to study links between the gut microbiota and the immune system in people with a liver disease called hepatocellular carcinoma (HCC). Objective: To study links between gut microbiota and the immune system in people with HCC. Eligibility: People at least 18 years old with HCC. They must be scheduled to have tumors removed by surgery. Design: People having surgery for primary liver tumors at the Mount Sinai Medical Center will be screened for this study. At the initial visit, blood, rectal swabs, urine, and stool will be collected. Participants will answer questions about their medical condition. Before surgery, blood, rectal swabs, urine, and stool will be collected. This will be done at a routine visit. When they have surgery, a piece of liver tissue with the tumor will be collected. This will be sent to the National Cancer Institute for tests. After surgery, blood, rectal swabs, urine, and stool will be collected 3 times. This will be done at routine visits.
