Active clinical trials for "Liver Neoplasms"

Percutaneous radiofrequency ablation is a commonly treatment for patients with liver cancer that cannot be surgically resected. During the procedure, patients need to keep awake and cooperate with the procedure, including deep breath and hold breath. However, intolerable pain generated during puncture and radiofrequency heating may cause body movements and interfere the procedure. Oxycodone is frequently used for analgesia but still insufficient. A recent study showed that dexmedetomidine-esketamine combination improves analgesia without increasing adverse events. After stopping infusion, the analgesic/sleep-promoting effects of dexmedetomidine-esketamine seemed to last for up to 24 hours. The investigators hypothesize that dexmedetomidine-esketamine combination as a supplement to oxycodone will improve sedation and analgesia in patients undergoing radiofrequency liver ablation of the liver.

Today, it is difficult to predict liver function after transplantation and therefore livers where poor function is assumed (marginal livers) become discarded. The study aim is to increase the number of available donor livers, especially for liver cancer patients, by pre-treating and testing marginal ones (extended criteria donor (ECD) livers) liver on a liver perfusion machine. A liver perfusion machine can simulate liver transplantation and enables functional/quality testing before transplantation. The machine will hopefully also make marginal livers more functional by reducing ischemia- & reperfusion injury. A marginal donor liver is perfused ex situ with oxygenated blood from a blood donor on a machine. The liver can be tested here for function using internationally recognized criteria. At the same time, the investigators will carry out analyzes with microdialysis which can give a better picture of organ function and damage. Additionally, various samples of the liver and perfusate will be collected. Liver that achieves criteria for transplantation will be offered to the recipient.

Sarcopenia is associated with the prognosis of HCC and cholangiocarcinoma. But there has been rare study focusing on the effect of sarcopenia on the prognosis of HCC treated with lenvatinib and anti-PD1.

Prospective single arm, single center observational study to evaluate Quality of Life (Qol) after stereotactic body radiotherapy for patients with hepatocellular cancer. Patients will receive work-up, treatment and follow-up exclusively as routinely done except additional quality of life measurements. Qol will be measured by standardized and validated EORTC questionaires at different time points during routine follow-up.

This longitudinal observational cohort study was designed to investigate factors that influencing the occurrence and long-term survival of patients with primary liver cancer. Basic informations and detailed diagnosis informations (AJCC/TNM stage, MELD score, Child-Pugh score, and BCLC stage) were collected by professional doctors. Clinical outcomes (death, recurrence, and metastasis) will be followed up every two years after therapy.

This prospective single arm double-blind study approved by the Ethics Committee of the institution, will be conducted on at the Oncology Institute of Vojvodina in Sremska Kamenica, Serbia. Patients with colo-rectal cancer liver metastases (CRLM) is presented to the multi-disciplinary team (MDT).Screening and enrolment is conducted after established of indication for resection. The surgeons assesses resection margin (RM) for every resected liver specimen (RLS) intra-operatively by inspection and palpation. These data will be compared with pathological RM examination as a "gold standard". Resection margin of 1 mm or more will be rated as negative RM (RM-) otherwise RM is positive (RM+). Taking the result of the pathohistological examination as "gold standard" it is determined that RM is true positive when the pathologist and surgeon agreed that the RM is positive. False negative RM is when the surgeon assesses RM as negative and pathologist as positive. The sensitivity of the surgical assessment of RM+ is defined as the rate of RM+ which was correctly identified. True negative RM is determined when the pathologist and surgeon agreed that it is negative RM. False positive RM defined when the surgeon assessed RM as positive, but pathologist found that it was RM-. The specificity of the surgical assessment of RM is defined as the rate of RM- which is correctly identified. Total accuracy represents the rate of correctly recognized positive and negative RM, relative to the total number of samples. Agreement between surgeon and pathologists finding will be analyzed as well as difference between them. Disease recurrence and disease-free survival (DFS) will be analyzed by RM.

This observational study will investigate the properties of image files standardly collected during radiation therapy treatment in a cross-section of liver cancer patients who received stereotactic ablative body radiation therapy (SABR) after trans-catheter arterial chemo emobilisation (TACE). Specifically, it will determine whether the radio-opaque contrast agents in the image files can be detected by tumour-tracking software (KIM).

Preoperative chemotherapy is often used for patients with colorectal cancer liver metastasis (CLM). Many small CLMs (<=2cm) may disappear after chemotherapy, while most of these are still alive. Ultrasonography (US) is a common imaging modality for the intraoperative detection tumor. Sonazoid is new echo-contrast agent, which is more stable and sensitive for detecting of small tumor. Investigators initially this prospective study to compare the detection performance before and after using sonazoid.

The purpose of this study is to collect information about people with fibrolamellar cancer (FLC). This study is a registry of people with FLC around the world. This study will involve collecting information about participants, their medical history and the regular medical care they receive for FLC. The study will not provide treatment for your cancer.

Patients with resectable solid primary cancers and even limited number of metastases are potentially curable. However, most patients develop recurrences despite surgery. Also, early detection of lung cancer with low dose CT screening may cure patients at an early stage. Circulating and disseminated tumor cell (CTC/DTC) and circulating cell-free (cf) DNA isolation from the blood, urine and bone marrow will increase understanding of cancer spread and advance knowledge to develop individualized therapies and improve screening.
