Description détaillée
OUTLINE:
Patients undergo CT perfusion sequence during the first 40 seconds of the baseline standard of care CT scan and during follow-up CT scans at 2 and possibly 4 months after chemotherapy, at 4-6 weeks after radiation therapy, or prior to definitive surgery.
After completion of the study, patients are followed up periodically for 2 years.

Expérimental: Diagnostic (CT perfusion sequence)
Patients undergo CT perfusion sequence during the first 40 seconds of the baseline standard of care CT scan and during follow-up CT scans at 2 and possibly 4 months after chemotherapy, at 4-6 weeks after radiation therapy, or prior to definitive surgery.

Délai |
|---|---|---|
|
Correlation between pre-treatment computed tomography (CT) tumor perfusion parameters and percentage of patients who achieve curative (R0) surgical resection after neoadjuvant chemotherapy
Délai: Up to 4 years
|
Assessed using logistic regression.
Receiver operating characteristic (ROC) curve analysis will be used to examine the sensitivity and specificity of different thresholds for each parameter.
|
Up to 4 years
|
|
Correlation between pre-treatment CT tumor perfusion parameters and tumor response after treatment
Délai: Up to 1 year
|
Will be defined by Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1.
Assessed using logistic regression.
ROC curve analysis will be used to examine the sensitivity and specificity of different thresholds for each parameter.
If multiple perfusion parameters are found to be predictive of response, a multivariate logistic regression model will be constructed with these variables.
ROC analysis will also be used to summary the predictive performance of the multivariate model.
|
Up to 1 year
|
|
Correlation of pre-treatment CT tumor perfusion parameters with overall survival
Délai: At 1 year
|
Assessed using Cox regression models.
Multivariate Cox models will be constructed if multiple parameters are found to be predictive of survival.
|
At 1 year
|
|
Correlation of pre-treatment CT tumor perfusion parameters with overall survival
Délai: At 2 years
|
Assessed using Cox regression models.
Multivariate Cox models will be constructed if multiple parameters are found to be predictive of survival.
|
At 2 years
|
|
Correlation of pre-treatment CT tumor perfusion parameters with progression free survival
Délai: At 1 year
|
Assessed using Cox regression models.
Multivariate Cox models will be constructed if multiple parameters are found to be predictive of survival.

At 1 year

|
Correlation of pre-treatment CT tumor perfusion parameters with progression free survival
Délai: At 2 years

|
Change in computed tomography (CT) tumor perfusion parameters (time to peak concentration)
Délai: Baseline to post-treatment (up to approximately one year)
|
The change in each CT tumor perfusion parameter between the pre-treatment scan and the post-treatment scan where response is assessed will be calculated.
These changes will be compared between the responders and non-responders using the t-test or Mann-Whitney test.
|
Baseline to post-treatment (up to approximately one year)
|
|
Change in CT tumor perfusion parameter (blood flow)
Délai: Baseline to post-treatment (up to approximately one year)
|
The change in each CT tumor perfusion parameter between the pre-treatment scan and the post-treatment scan where response is assessed will be calculated.
These changes will be compared between the responders and non-responders using the t-test or Mann-Whitney test.

|
Change in CT tumor perfusion parameter (blood volume)
Délai: Baseline to post-treatment (up to approximately one year)
|
The change in each CT tumor perfusion parameter between the pre-treatment scan and the post-treatment scan where response is assessed will be calculated.
These changes will be compared between the responders and non-responders using the t-test or Mann-Whitney test.

Baseline to post-treatment (up to approximately one year)
|
|
Change in CT tumor perfusion parameter (Ktrans)
Délai: Baseline to post-treatment (up to approximately one year)
|
The change in each CT tumor perfusion parameter between the pre-treatment scan and the post-treatment scan where response is assessed will be calculated.
These changes will be compared between the responders and non-responders using the t-test or Mann-Whitney test.
