Trial summary

Oral squamous cell carcinoma is a major public health problem , especially in West Asian countries. Cyclin D1 accelerates cell cycle and thus may be implicated in uncontrolled cellular proliferation and tumor progression. Read more about this study

About this study

Oral squamous cell carcinoma is a major public health problem , especially in West Asian countries. Cyclin D1 accelerates cell cycle and thus may be implicated in uncontrolled cellular proliferation and tumor progression.

Read the detailed description

Oral squamous cell carcinoma is a major public health problem in different parts of the world. Despite marvelous improvement in treatment modalities -surgical approaches, chemotherapy and radiotherapy- the overall survival ad disease-free survival remain unchanged. so, there a need for studying tumor biology and micro environment. Cyclin D1 is a protein which enhances cell cycle through binding with cyclin-dependent kinases. Over expression of Cyclin D1 may by responsible for the aggressive behavior of oral squamous cell carcinoma through uncontrolled cellular proliferation. in current study, we have detected Cyclin D1 expression in 34 cases of oral squamous cell carcinoma. We detected relationship between intensity of expression and certain parameters as tumor grade, lymphovascular and perineural invasion.

What is being measured

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

  1. immunohistochemical expression of Cyclin D1 in Oral Squamous Cell Carcinoma

    detection of both intensity staining and tumor cells percentage of Cyckin D1 in studied cases of Oral Squamous Cell Carcinoma, and then relate intensity and percentage of Cyclin D1 with patients' ages, sexes, tumor grade, tumor site , lymphovascular invasion and perineural invasion.

    Measured: 6 months

Questions about this trial

What is this clinical trial studying?

An observational study of Oral Squamous Cell Carcinoma (OSCC), run by Sohag 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 1 inclusion and 3 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 21 Aug 2026. 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?

immunohistochemical expression of Cyclin D1 in Oral Squamous Cell Carcinoma (time frame: 6 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT07778615, which also lists 1 linked publication.

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 21 Aug 2026.
