Assessment

Primary outcomes

The correlation between pretreatment ADC value of diffusion MRI and pathologic response evaluated by Evans grade in patients with unresectable pancreatic carcinoma (URPC) who undergo neoadjuvant therapy.

Key secondary outcomes

1. The correlation between pretreatment ADC value at the abutment site of URPC and the rate of tumor cell destruction.
2. The correlation between posttreatment ADC value at the abutment site of URPC and the rate of tumor cell destruction.
3.The correlation between the ratio of posttreatment/pretreatment ADC value at the abutment site of URPC and the rate of tumor cell destruction.
4.The correlation between pretreatment ADC value of URPC tumor in a largest diameter and the rate of tumor cell destruction.
5.The correlation between the ratio of posttreatment/pretreatment ADC value of BRPC tumor in a largest diameter and the rate of tumor cell destruction.
6.ADC Cut-off value which predict more than 50% and less than 10% in tumor cell destruction rate.
7.The correlation between the ratio of posttreatment/pretreatment ADC value of URPC tumor in a largest diameter and the ratio of posttreatment/pretreatment SUV max.
8.ADC Cut-off value and SUV max cut-off value which predict survival time after surgery more than 2 years and less than 2 years.
9. The comparison of the accuracy of prediction for pathological diagnosis at abutment site between the ratio of posttreatment/pretreatment ADC value and CT scan.
10. Three correlation between high ADC value/low ADC value/the ratio of posttreatment/pretreatment ADC value and survival time after surgery.
11. Three correlation between high ADC value/low ADC value/the ratio of posttreatment/pretreatment ADC value and decreasing rate of CA19-9 value.
12.The correlation between tumor's limb sign in diffusion MRI and the rate of tumor cell destruction more than 10%.

Results

Pre/post-treatment whole tumor ADC value correlated with tumor cell destruction rate among all parameters (R=0.630/0.714, P<0.001/<0.0001). The post-treatment cutoff value of vascular abut site ADC for discriminating between grade<IIb and >=grade IIb was determined as 1.42x10-3 mm2/s and predicts R0 curability. For histological response, the post-treatment whole tumor ADC cutoff value for discriminating between grade<IIb and >= grade IIb was determined as 1.40x10-3 mm2/s.

Baseline Characteristics

We prospectively reviewed 28 patients with BRPC or LAPC who underwent diffusion-weighted magnetic resonance imaging before neoadjuvant chemotherapy and surgery.

Participant flow

Patients were enrolled after the diagnoses of borderline resectable pancreatic cancer. We elucidate correlation between pre/post-treatment whole tumor apparent diffusion coefficient (ADC) value and tumor cell destruction rate. We verify whether post-treatment vascular abut site ADC value predicts R0 curability of borderline resectable pancreatic cancer (BRPC) and locally advanced pancreatic cancer (LAPC). 

Adverse events

None

Outcome measures

We elucidate correlation between pre/post-treatment whole tumor apparent diffusion coefficient (ADC) value and tumor cell destruction rate. We verify whether post-treatment vascular abut site ADC value predicts R0 curability of borderline resectable pancreatic cancer (BRPC) and locally advanced pancreatic cancer (LAPC). Analyses for correlation between percent tumor cell destruction and various parameters were performed. Strong parameters were assessed for ability to predict therapeutic histological response and R0 curability.
