About this study

The aim of this study is to evaluate the effectiveness of cryotherapy as a therapeutic option for oral lesions.

Read the detailed description

Low-temperature applications were originally employed by the Egyptians to treat pain, and subsequently during the Franco-Prussian War for severed limbs. Hippocrates advocated the application of cold to lessen bruising, bleeding, and discomfort, while John Hunter wrote in 1777 that "the local tissue response to freezing includes local tissue necrosis, vascular stasis, and excellent healing." Using a solution of salt and ice, James Arnott (1851) was the first to describe and demonstrate this freezing technique for malignant breast tumors.

The term "cryotherapy" was used in 1908 to describe the use of extremely low temperatures to cure skin lesions. Currently, cryotherapy involves cooling the body's surface without destroying tissue, whereas in cryosurgery, sick tissues are frozen to death.

In the technique, several cryogens include: liquid nitroglycerine (-196 °C), Nitrous oxide (0°C), Solid CO2 (-78o C), Chlorodifluoromethane (-41°C), Dimethyl ether (-24 °C) and propane (-42 °C).

The intralesional technique, open method, or closed method can all be used to apply cryogens. The best application approach for big superficial cutaneous lesions is an open spray technique, in which the spray's nozzle is situated 1 cm away from the skin's surface, and the lesion is destroyed using either a paintbrush technique or a spiral technique.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • CryotherapyOther

    Cryotherapy can be done in two ways:

    1. Open technique: Using cotton swabs or a cryogun spray, the cryogen is delivered directly to the lesion in this technique.
    2. Closed technique: Cryo-probes are used to apply the cryogen to the lesion in this procedure.

    The spray's nozzle of the Cryogun spray -50 ◦C was situated 1 cm away from the skin's surface and applied on the oral lesion for 30 seconds. Each freezing cycle lasted 10 to 30 seconds, with the subsequent 60-second thaw interval lasting twice as long as the freezing time. The ice ball that formed during freezing was totally melted before the subsequent freezing process could begin.

    The application process should went from the core out to the edges. The management of lesions that are too big to be frozen by a single spray requires many overlapping treatments of liquid nitrogen. Mucoceles and erosive lichen planus took 30 to 50 seconds to freeze, whereas fibromas and leukoplakia took 60 to 70 seconds.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The degree of pain

    The degree of pain was assessed by using Visual Analogue Scale (VAS). VAS (0 represents "no pain" while 10 represents "the worst pain imaginable"), which was documented on the 1st, 3rd, 7th, 21st days after the procedure

    Measured: 21st days postoperatively

Secondary outcomes (2)
  1. Epithelization of the lesion

    Number of Participants with epithelization of the lesion was evaluated in the 1st postoperative month

    Measured: 1st month postoperatively

  2. The incidence of recurrence of the lesion

    Recurrence of the lesion was evaluated in the 2nd postoperative month

    Measured: 2nd month postoperatively

Questions about this trial

What is this clinical trial studying?

A study testing Cryotherapy in people with Cryotherapy and Oral Lesions, run by October 6 University at 1 site in Egypt.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 9 Jan 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Egypt. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The degree of pain (time frame: 21st days postoperatively). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 9 Jan 2024.
