Observational Study of TEG Indices in Cancer Patients Undergoing Surgery

This study is looking at how blood clotting measurements, called TEG indices (thromboelastography), relate to different cancers like liver, esophageal, colorectal, and lung adenocarcinoma. Researchers want to see if these TEG indices can help predict how severe the cancer is, if it will come back, how long people live, and if there will be bleeding or clotting problems after surgery. You may be able to join if you are 18 or older and have a new diagnosis of one of these cancers. The study is also looking at healthy individuals as a control group. The main goals are to see how TEG indices connect to the cancer's stage, and to identify potential complications before and after surgery. The current recruitment status is unclear.

Study design
This is an observational study planning to enroll 400 participants. It is not specified if it is randomized or blinded.
What's involved
Participants will provide blood samples for TEG indices. The specific number of visits or duration of participation is not detailed.
Compensation
Not stated in the trial record.
Follow-up
TEG indices, disease burden, and pre-operative complications will be measured at one year.
