About this study

Official title: Effect of Propofol and Sevoflurane Anesthesia on HSP70 Expression in Tumor Cells A Prospective, Single-center, Pilot, Randomized Study

The goal of this clinical trial is to learn if sevoflurane-based inhalational anesthesia (s-IA) and propofol-based total intravenous anesthesia (p-TVA) have different effects on HSP70 expression in different types of tumour cells. The main questions it aims to answer are:

  • if p-TVA/s-IA increase or suppress HSP70 expression in tumor cells in comparison with a pre-anesthesia level;
  • does this change in HSP70 expression cause any difference in vital characteristics of tumor cells, such as proliferation, apoptosis, colony formation and migration.
Read more

Researchers will compare p-TVA with s-IA by ability of these types of anesthesia to change the HSP70 expression level and modulate HSP70-mediated effects in tumor cells.

Participants will:

  • be randomly allocated to p-TVA or s-IA groups;
  • donate 12 ml of blood before anesthesia induction and 12 ml after 2 hours of anesthesia.

The blood serum will be used to prepare cell medium. After exposure to this medium, cells from different tumor types will be investigated using cytological and molecular biological methods.

Read the detailed description

This study will be conducted in adult cancer patients who undergo planned radical or palliative tumor resection and signed informed consent. Patients with diabetes mellitus, HIV, hepatitis B and C, as well as patients who undergo emergency surgery will not be included to the study. Patients will be randomly allocated to propofol-based TVA (p-TVA) and sevoflurane-based IA (s-IA) groups. After the collection of blood before the anesthesia induction and in 2 hours of anesthesia, probes will be centrifuged to prepare serum. Cell medium will contain 50% of blood serum. Different tumor cell lines (human lung adenocarcinoma A549, large cell lung carcinoma NCI-H460, human colorectal adenocarcinoma DLD1) will be exposed to the cell medium for 4 hours what corresponds to an approximate duration of anesthesia for oncology surgery. HSP70 expression level will be determined using SDS-PAGE (polyacrilamide gel electrophoresis) and Western-blot analysis (intracellular HSP70 content), ELISA of cell medium (extracellular HSP70 expression) and confocal microscopy.

The A549 cell line with stable knockdown of HSP70 developed by shRNA will be used to distinguish HSP70-based effects of cell medium from p-TVA and s-IA groups on vital characteristics of tumor cells, including proliferation (MTT assay), apoptosis (LDH cytotoxicity assay), colony formation and migration (the Wound healing assay).

Researchers will compare HSP70 expression levels and vital characteristics of tumor cells exposed to patient serum before and after each type of anesthesia, as well as p-TVA group with s-IA group.

What is being measured

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

  1. HSP70 expression in tumor cells in vitro

    Increased intracellular and extracellular HSP70 content in different types of tumor cells measured by SDS-PAGE/Western blotting and ELISA, respectively.

    Measured: 24 hours after exposition with patients serum.

Secondary outcomes (4)
  1. LDG cytotoxicity

    Reduction of apoptosis mediated by HSP70 pathway in different types of tumor cells measured by LDG cytotoxicity assay using HSP70-knockdown cell line.

    Measured: 24 hours after exposition with patients serum.

  2. MTT test

    Increase in proliferation mediated by HSP70 pathway in different types of tumor cells measured by MTT assay using HSP70-knockdown cell line.

    Measured: 24 hours after exposition with patients serum.

  3. Wound healing test

    Increase in cell migration mediated by HSP70 pathway in different types of tumor cells measured by the Wound healing assay.

    Measured: 72 hours after exposition with patients serum.

  4. Cell colonies formation

    Increase in ability to form colonies mediated by HSP70 pathway in different types of tumor cells evaluated by direct microscopy using HSP70-knockdown cell line.

    Measured: 7 days after exposition with patients serum.

Questions about this trial

What is this clinical trial studying?

A Early Phase 1 study testing Propofol and Sevoflurane in people with Anesthesia and Cancer Recurrence, run by Saint Petersburg State University, Russia at 1 site in Russia.

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 4 inclusion and 5 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: under way, not looking for participants, as of the sponsor's last update on 4 May 2025. 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 Russia. 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.

What does this phase mean?

Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

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?

HSP70 expression in tumor cells in vitro (time frame: 24 hours after exposition with patients serum.). 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 4 May 2025.
