PET/CT Scan as a Tool to Rationalize the Treatment of Patients With Advanced ColoRectal Cancer Undergoing First-line Medical Treatment (PETRA2 - CRC)

March 23, 2023 updated by: National Cancer Institute, Naples

Study of the Role of Metabolic Response Measured by PET/CT Scan After 1 Cycle of First-line Therapy in Patients With Advanced Colorectal Cancer (CRC)

The purpose of this study is to test whether an early metabolic response, measured by PET/CT scan after the first cycle of chemotherapy, is able to predict which patients with advanced CRC have a better prognosis.

Description

Inclusion Criteria:

  • Diagnosis histologically confirmed colorectal carcinoma
  • stage IV disease
  • patients eligible for standard first-line treatment medical therapy (chemotherapy, and when indicated in association with EGFR inhibitor and/or antiangiogenic) for advanced disease, at diagnosis or after primary surgery.
  • At least one target or non-target lesion according to RECIST revised version 1.1.
  • Age > or = 18 years .
  • ECOG PS 0-2.
  • Life expectancy > 3 months.
  • Signed informed consent.

Exclusion Criteria:

  • Uncontrolled diabetes (glucose > 200 mg/dl
  • Any other malignancies within 5 years (except for adequately treated carcinoma in situ of the cervix or basal or squamous cell skin cancer or surgically resected prostate cancer with normal PSA).
  • Pregnant or lactating females.
  • Previous medical therapy for metastatic disease (prior surgery, radiation therapy are permitted, as well as adjuvant medical therapy completed at least 6 months prior to study entry).
  • Any poorly controlled illness (including active infections, significant hepatic, renal, metabolic or cardiac disease, myocardial infarction within previous 12 months) that may, according to physician's judgement, interfere with the patient's ability to undergo chemotherapy and/or the examinations within the study protocol
  • Inability to provide informed consent.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
change from baseline in highest value SUVmax (maximum standardized uptake values in PET/CT scan)
Time Frame: 2 weeks
To validate as prognostic factor, in terms of overall survival,early metabolic response, defined as a reduction of more than 50% of the highest value of SUVmax recorded at PET/CT scan after one cycle of chemotherapy, compared to the highest value of SUVmax recorded baseline examination
2 weeks

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change from baseline in SUVmaxsum, TLGmax and TLGmaxsum
Time Frame: one year
to describe and validate early metabolic response as a prognostic factor (in terms of progression free survival), using the sum of the SUVmax (SUVmaxsum) , the highest value of TLG (TLGmax), the sum of TLG ( TLGmaxsum).
one year
correlation among SUVmax, SUVmaxsum, TLGmax, TLGsum with progression-free survival after first-line pharmacologic therapy
Time Frame: one year
prognostic role of early metabolic response (defined according the above reported 4 parameters) in terms of progression free survival after a first line pharmacologic therapy
one year
correlation among SUVmax, SUVmaxsum, TLGmax, TLGsum with objective response
Time Frame: 3 months
To describe the association between early metabolic response (defined according the above reported 4 parameters) and objective response according RECIST criteria, measured after 3 cycles of chemotherapy
3 months
prognostic value of metabolic response (SUVmax, SUVmaxsum, TLGmax, TLGsum) and recist response
Time Frame: one year
one year

Other Outcome Measures

Outcome Measure
Time Frame
prognostic value of metabolic response (SUVmax, SUVmaxsum, TLGmax, TLGsum) by different cut off values (other than 50% reduction)
Time Frame: one year
one year
