What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting This study
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study looks at three ways to treat subcapsular hepatocellular carcinoma (HCC), a type of liver cancer near the surface of the liver. It compares two minimally invasive microwave ablation methods—one that avoids piercing the tumor and one that does—against traditional surgical removal. The goal is to see which approach best controls the tumor, prevents recurrence, and helps people live longer. About 180 patients with small subcapsular HCC will be followed over time to measure outcomes like local tumor control, disease-free survival, and overall survival.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Microwave ablation (no-touch and tumor-puncture techniques) compared with surgical resection
What this could lead to
If no-touch microwave ablation proves as effective as surgery, it could offer a less invasive option for people with subcapsular liver cancer, potentially reducing recovery time and risks.
What could go wrong
This is an observational study, not a randomized trial, so results may be influenced by patient differences. Microwave ablation may not achieve the same long-term control as surgery, and there are risks of bleeding, infection, or incomplete tumor destruction.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

The study population will consist of adult patients with confirmed subcapsular hepatocellular carcinoma (HCC) who receive no-touch microwave ablation, tumor-puncture microwave ablation, or surgical resection as part of routine clinical practice. The diagnosis of HCC will be established according to the practice guidelines of the American Association for the Study of Liver Diseases (AASLD). Subcapsular HCC will be defined based on imaging findings, with the shortest distance between the tumor margin and the liver capsule being ≤3 mm as confirmed by ultrasound, computed tomography (CT), or magnetic resonance imaging (MRI). Eligible patients will be prospectively enrolled and followed to evaluate treatment efficacy, safety, recurrence patterns, and long-term survival outcomes.

Inclusion Criteria: Diagnosed with hepatocellular carcinoma (HCC) confirmed by pathological biopsy or clinical diagnostic criteria; Imaging examinations including ultrasound confirm that the HCC lesion is subcapsular, defined as the minimum distance between the tumor and liver capsule ≤ 3 mm; Single tumor with maximum diameter ≤ 5 cm, or up to 3 multiple tumors each with maximum diameter ≤ 3 cm; Liver function classified as Child-Pugh grade A or B; No invasion of adjacent blood vessels or vital organs; no tumor thrombus in the main portal vein or hepatic vein, and no extrahepatic metastasis. \- Exclusion Criteria:Patients with dysfunction of vital organs such as heart and lungs; Patients who received preoperative radiotherapy, chemotherapy, targeted therapy or immunotherapy, or patients complicated with other malignant tumors; Poor follow-up compliance and inability to complete the standardized follow-up procedures. \-
