NCT06799182

Brief Summary

The aim of this interventional study is to determine the impact of periodontal disease and periodontal treatment on patients with colorectal cancer. The main questions were:

  1. 1.Does periodontal treatment affect the levels of C-reactive protein in the blood of patients undergoing cancer treatment?
  2. 2.Can the investigators isolate periodontal pathogenic bacteria Fusobacterium nucleatum and Porphyromonas gingivalis from the mucosa of cancerous colon tissue using the method of quantitative culture?

Outcome Measures

Primary Outcomes (2)

  • CRP levels

    Measurement of CRP levels in the blood of patients with colorectal cancer at the first examination by the oncological surgeon, on the first and second day after colon resection, and at the first follow-up examination by the oncological surgeon.

    From the enrollment to the date of first documented progression at 16 weeks

  • The proportion of Fusobacterium nucleatum and Porphyromonas gingivalis

    Using quantitative culture for detection of periodontal bacteria Fusobacterium nucleatum and Porphyromonas gingivalis in the cancer altered intestinal musoca and comparing it with the status in the periodontal pocket

    From the first dental exam to the resective colon surgery at 2 weeks

Study Arms (2)

Patients with colorectal cancer who recived periodontal treatment

EXPERIMENTAL

Patients with colorectal cancer were treated for periodontal disease based on the condition of their periodontal tissues.

Procedure: periodontal treatment

Patients with colorectal cancer who did not recived periodontal treatment

NO INTERVENTION

Due to ethical concerns, we selected patients who had completed cancer therapy before the start of our study for the control group, and who met the inclusion criteria based on the completed questionnaires.

Interventions

Based on the results of the dental examination and the diagnosis of the periodontal tissue condition according to the new classification of periodontal disease, we performed appropriate non-surgical treatment of periodontal disease, provided oral hygiene instruction, and took a biofilm sample from the deep periodontal pocket. We then collected a sample of the altered mucosa during bowel surgery for colorectal cancer and conducted a microbiological investigation using quantitative culture to compare the presence of Fusobacterium nucleatum and Porphyromonas gingivalis in the pariodontal pocket and altered intestinal mucosa.

Also known as: Biopsy of the intestinal mucosa for quantitative culture, samples of periodontal biofilm for quantitative culture
