About this study
Official title: Monkeypox and Cancer: a Pan-cancer Based Multi-omics Analysis and Single Cell Sequencing Analysis-Experimental Studies
Colorectal cancer tissue sections were obtained according to the inclusion criteria. The formalin was used to immersed all cancer specimens. And tissues were cut to 5 μm thickness and placed on glass slides before staining. Endogenous peroxidase activity was inhibited and blocked by de-paraffinizing, rehydrating, and using 5% bovine serum albumin at 37ºC for 30 min. The treated sections were incubated with anti-FOS (promab 30360) at 4ºC overnight and washed three times with PBS. After that, it is required that incubation with secondary anti-peroxidation sunflower at 37ºC for 30 minutes. After washing three times again with PBS, the sections were developed in diaminobenzidine and microscopic images were made by light microscopy.

Immunohistochemical staining with anti-FOSDiagnostic test
The tissue sections were incubated with anti-FOS (promab 30360) at 4ºC overnight and washed three times with PBS. After that, it is required that incubation with secondary anti-peroxidation sunflower at 37ºC for 30 minutes. After washing three times again with PBS, the sections were developed in diaminobenzidine and microscopic images were made by light microscopy.
| Study group | Role | What they receive |
|---|---|---|
| Test group-stained by FOS antibody | Experimental | Sixty colorectal cancer tissue sections were included. The tissue was cut to 5 μm thick and placed on a glass slide for staining. Endogenous peroxidase activity was inhibited and blocked by deparaffin, rehydration, and treatment with 5% bovine serum albumin for 30 min at 37 ° C. The treated sections were incubated with anti-FOS (promab 30360) overnight at 4 ° C and washed three times with PBS. After that, it was required to incubate with secondary anti-peroxidation sunflower for 30 min at 37 ° C. After washing three times with PBS, the images were developed in diamine benzidine and micrographs were obtained under a light microscope.

Measured: Participants were followed up for 3 years, including outpatient follow-up and telephone follow-up.

Questions about this trial
What is this clinical trial studying?
A Phase 2/3 study testing Immunohistochemical staining with anti-FOS in people with Colorectal Cancer and Monkey Pox, run by xiaoliang Huang at 1 site in China.
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 1 inclusion and 1 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: status not confirmed, as of the sponsor's last update on 26 Jan 2023. 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 China. 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 combined phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Xiaoliang Huang, Dr. (0086-13617713823, xiaoliang@sr.gxmu.edu.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Original survival (time frame: Participants were followed up for 3 years, including outpatient follow-up and telephone follow-up.). 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 26 Jan 2023; AzTrials last refreshed its copy on 8 Nov 2026.
