Summary

This research article investigates the use of Fluorodeoxyglucose Positron Emission Tomography (FDG-PET) integrated with Computed Tomography (CT) in the initial staging of cervical cancer. The study focused on women with and without HIV, aiming to:

1. Assess Impact on Staging: Determine how FDG-PET/CT improves the accuracy of staging for patients with FIGO stage IB2 to IVA cervical cancer.
2. Predictive Role of Metabolic Parameters: Evaluate the ability of FDG-PET/CT metabolic parameters (SUVmax, SUVmean, MTV, and TLG) to predict distant metastasis.

Key Findings:

- Patient Characteristics: 126 women with cervical cancer were studied, including 73 HIV-infected individuals. HIV-infected patients were younger and had more advanced disease compared to uninfected patients.
- Staging Improvement: FDG-PET/CT upstaged 65 patients, 32 of whom were advanced to stage IVB. The addition of FDG-PET/CT improved staging accuracy in about half of the patients.
- Metabolic Parameters and Metastasis: In a statistical analysis adjusted for FIGO stage, MTV and TLG of the primary tumor were significantly associated with distant metastasis. All metabolic parameters (SUVmax, SUVmean, MTV, and TLG) performed well in predicting metastasis, with areas under the curves ranging from 0.63 to 0.84.

Conclusion:

Incorporating FDG-PET/CT into pre-therapy assessment of cervical cancer enhances staging accuracy and the predictive power of metabolic parameters for distant metastasis, particularly in HIV-associated invasive carcinoma of the cervix.
