Radiomic features from [18F] FDG PET/CT imaging, including statistical and texture analysis, can predict cervical cancer recurrence and chemotherapy response. These parameters offer valuable insights into treatment effectiveness and patient outcomes.
Area of Science:
- Oncology
- Radiology
- Medical Imaging
Background:
- Cervical cancer staging (IIIC1-IVB) requires accurate assessment of disease progression and treatment response.
- Radiomics, extracting quantitative features from medical images, shows promise in non-invasively characterizing tumors.
Purpose of the Study:
- To evaluate the utility of first-order statistics (FOS) and Gray-Level Co-occurrence Matrix (GLCM) texture analysis of [18F] FDG PET/CT scans in assessing cervical cancer.
- To correlate radiomic parameters with chemotherapy response, recurrence, and patient age.
Main Methods:
- Retrospective analysis of 83 patients with stage IIIC1-IVB cervical cancer.
- Acquisition of [18F] FDG PET/CT scans before and after chemotherapy.
- Calculation of FOS and GLCM texture parameters, including SUVmax, SUVmean, TLG, MTV, ASP, E, COR, En, and H.
Main Results:
- Significant differences in metabolic and textural parameters were observed between pre- and post-therapy scans.
- Pre-treatment coefficient of variation (COV) moderately correlated with recurrence (R=0.34, p=0.001).
- Post-treatment contrast (C) showed moderate correlation with patient age (R=0.3, p=0.0038), while Energy (En) and Homogeneity (H) strongly correlated with chemotherapy response (R=0.54 and R=0.46, respectively).
Conclusions:
- Pre- and post-treatment [18F] FDG PET/CT radiomic parameters, encompassing statistical and textural features, are significant predictors of cervical cancer recurrence and chemotherapy response.
- These findings highlight the potential of radiomics to guide treatment decisions and improve patient management in cervical cancer.

P-value
P-value stands for the probability value. P-value is the probability that, if the null hypothesis is true, the results from another randomly selected sample will be as extreme or more extreme as the results obtained from the given sample.
A large P-value calculated from the data indicates to not reject the null hypothesis. But a higher P-value does not mean that the null hypothesis is true. The smaller the P-value, the more...
