Study summary

The goal of this clinical trial is to verify the safety and clinical benefit of pulsed electric field (PEF) treatment of advanced or unresectable esophageal squamous cell carcinoma patients.

The main questions it aims to answer are:

  • Safety and feasibility of PEF treatment of patients with advanced or unresectable esophageal squamous cell carcinoma.
  • Locoregional control of ablated lesions and quality of life assessment.
  • Local and peripheral immunoregulation effect.

Inclusion criteria

  1. Aged 20 years or older when signing the form.
  2. Able to provide written informed consent, and understand and follow the study requirements and assessment schedule.
  3. Screening period tumor patients performance status score of 0 or 1.
  4. Laboratory test data within 7 days before the planned PEF treatment date during the screening period must meet the following standards.

    • (ANC) ≥1500 cells/mm3
    • count ≥100,000 cells/mm3
    • ≥9 g/dL or ≥5.6 mmol/L
    • Serum total ≤ 1.5 x .
  5. Females of must have a negative serum pregnancy test at screening and be willing to undergo additional pregnancy testing during the study.

Exclusion criteria

Exclusion Criteria:

  1. Subjects with active respiratory tract infection who need antibiotic or antiviral treatment;
  2. Patients with locally advanced ESCC whose tumors can be surgically removed by the investigator or can be potentially cured by radical chemoradiotherapy according to the judgment of local investigators.
  3. Patients with esophageal lesions that severely invade adjacent organs (esophagus/bronchus or esophagus/aorta) and are assessed as high-risk esophageal leakage/fistula by the investigator.
  4. Evidence of complete esophageal obstruction that is not suitable for treatment, and gastroscopy cannot be performed.
  5. Patients with a history of esophageal stent implantation for esophageal obstruction;
  6. Patients with a history of gastrointestinal bleeding in the past 4 weeks, or gastroscopy indicates a high risk of tumor ulcer bleeding.
  7. Patients with obstruction caused by anastomotic stenosis without esophageal primary lesions after previous esophageal cancer surgery.
  8. Patients with active or .
  9. Any active malignant tumor within 5 years before screening.
  10. Subjects have undergone metal implantation surgery such as esophageal stents and airway stents. Or the patient has an implantable cardioverter-defibrillator, pacemaker or other implantable electronic device.
  11. Patients with positive test.
  12. Subjects are currently participating in other research clinical trials;
  13. Subjects who are considered by the investigator to have other high-risk conditions and are not suitable for gastroscopy and surgery;
  14. Subjects who have adverse events that have not yet returned to baseline or stable levels due to previous anti-tumor treatment, except for adverse events that do not pose safety risks (such as hair loss and abnormal values of specific laboratory tests)
Terms in these criteria, in plain language(11)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

ECOG performance status

A scale of how much an illness limits everyday activity. For people being assessed to join a study, scores run from 0 (fully active) to 4; lower is more active.

0
Fully active, no restrictions.
1
Limited in strenuous activity, but walking and able to do light work, such as housework or office work.
2
Walking and able to look after yourself, but unable to work; up and about more than half of waking hours.
3
Able to look after yourself only in part; in bed or a chair more than half of waking hours.
4
Unable to look after yourself at all; in bed or a chair all day.

Studies most often ask for 0–1 or 0–2. Your doctor gives the score; the WHO scale uses the same steps. The full scale also has 5, which records death.

Absolute neutrophil count (ANC)

The number of neutrophils, white blood cells that help fight infection, in a given amount of blood. Too few raises the risk of infection.

It is a count, not a percentage of the white cells. Limits are written in units that mean the same: ≥ 1.5 × 10⁹/L is ≥ 1,500 per mm³ (µL). Each lab has its own reference range.

Platelets

Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.

Hemoglobin (Hb)

The protein in red blood cells that carries oxygen. A low level is anaemia, which can cause tiredness and breathlessness. Measured in g/dL or g/L (9 g/dL is 90 g/L).

Bilirubin

A yellow substance made when red blood cells are broken down, which the liver clears. A high level can mean a problem with the liver or the bile ducts.

Criteria often allow more for people with Gilbert’s syndrome, a harmless inherited condition that raises bilirubin.

ULN (upper limit of normal)

The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.

“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

Leptomeningeal disease

Cancer that has spread to the leptomeninges, the thin layers covering the brain and spinal cord, and the fluid between them. It is not the same as brain metastases.

Criteria often treat it separately, and many studies leave it out even where treated brain metastases are allowed.

Brain metastases

Cancer deposits in the brain from a cancer that started elsewhere in the body (CNS metastases include the spinal cord).

Studies differ: some leave out any brain metastases, some accept ones treated and stable for some weeks. Check what this study allows.

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.
