Neoadjuvant Short-Course Photon Radiation: At dose level 1, a total dose of 30 Gy in 10 fractions (3 Gy/day) was prescribed to the 95% isodose and administered 5 days per week over 12 days. Chemotherapy: Capecitabine was given orally 825 mg/m2 BID (total 1650 mg/m2 per day) for ten consecutive weekdays, beginning on the morning of the first day of radiation therapy.

Neoadjuvant Short-Course Photon Radiation Therapy Maximum Tolerated Dose (MTD) [Phase I]
時間枠：within 3 weeks of the start of chemoradiation therapy
|
Neoadjuvant short-course photon radiation therapy MTD in combination with capecitabine 825 mg/m2 orally BID for ten consecutive weekdays, beginning on the morning of the first day of radiation therapy is determined by the number of patients who experience a dose limiting toxicity (DLT).
See subsequent primary outcome measure for the DLT definition.
The MTD is defined as the highest dose at which fewer than one-third of patients experience a DLT.
If none of 3 initial patients or only 1 of 6 patients have a DLT on dose level 3 then 6 additional patients are treated at this dose.
If during this expansion, the rate of DLT exceeds 30% then the next lower dose level is declared the MTD.
If no DLTs are observed, the MTD is not reached.

Dose Limiting Toxicity (DLT) [Phase I]
時間枠：within 3 weeks of the start of chemoradiation therapy

DLT occurring within 3 weeks of the start of chemoradiation therapy was defined as: Grade 3 non-hematologic or hematologic toxicity requiring interruption of >7 days (d) of chemo or >3d chemoradiation; Grade 4 non-hematologic; Grade 4 neutropenia or thrombocytopenia; Treatment-related death; Delays in surgery >3 weeks due to treatment-related toxicity.
A 30% increase in any surgical complication rate beyond those previously established rates (readmission rate: 16%; pancreatic fistula/intra-abdominal abscess/infection rate: 27%, major intra-abdominal bleeding requiring return to OR: 1.6%, delayed gastric emptying: 4.4%, and superficial wound infection rate: 8%) was also considered a DLT.

Local Recurrence Rate [Phase II]
時間枠：Disease was assessed radiologically at baseline and after treatment every 6 months for first 2 years and annually in years 3-5.
|
Local recurrence rate is defined as the proportion of patients with evidence of tumor recurrence within the radiation field based on RECIST criteria.
Per RECIST 1.0 for target lesions, PD is at least a 20% increase in sum LD of target lesions, taking as reference the smallest sum LD recorded since the treatment started or appearance of new lesions.
For non-target lesions, PD is the appearance of one or more new lesions and/or unequivocal progression of existing non-target lesions.
|
Disease was assessed radiologically at baseline and after treatment every 6 months for first 2 years and annually in years 3-5.
|
|
Pathologic Response Rate [Phase II]
時間枠：Assessed after resection; Patients underwent resection of their pancreatic cancer up to 3 weeks after completion of chemoradiation therapy
|
Pathologic response rate is the proportion of patients with the pathologic specimen absent any viable tumor cell.
Pathological review of the pancreaticoduodenectomy specimen will be performed according to the AJCC Staging Classification, 6th edition.
Initial gross evaluation and identification of resection margins will be performed jointly by the surgeon and the pathologist.
|
Assessed after resection; Patients underwent resection of their pancreatic cancer up to 3 weeks after completion of chemoradiation therapy
|
|
Progression-Free Survival (PFS) [Phase II]
時間枠：Disease was assessed radiologically at baseline and after treatment every 6 months for first 2 years and annually in years 3-5.
|
Progression-free survival based on the Kaplan-Meier method is defined as the duration of time from study entry to documented disease progression (PD) or death.
Per RECIST 1.0 criteria: progressive disease (PD) is at least a 20% increase in the sum of longest diameter (LD) of target lesions taking as reference the smallest sum LD recorded since the treatment started or the appearance of one or more new lesions.
PD for the evaluation of non-target lesions is the appearance of one or more new lesions and/or unequivocal progression of non-target lesions.
Patients alive whose disease had not progressed are censored at date of last disease evaluation
|
Disease was assessed radiologically at baseline and after treatment every 6 months for first 2 years and annually in years 3-5.
|
|
Surgical Morbidity Rate [Phase II]
時間枠：Assessed after resection; Patients underwent resection of their pancreatic cancer up to 3 weeks after completion of chemoradiation therapy
|
The proportion of patients experienced any grade 3-4 adverse event based on CTCAEv3 related to the surgery (attribution possible, probable, definite) as reported on case report forms.
|
Assessed after resection; Patients underwent resection of their pancreatic cancer up to 3 weeks after completion of chemoradiation therapy
|
|
Surgical Mortality Rate [Phase II]
時間枠：Assessed up to 30 days after resection; Patients underwent resection of their pancreatic cancer up to 3 weeks after completion of chemoradiation therapy
|
The proportion of patients with a death related to the surgery (CTCAEv3 attribution possible, probable, definite).
|
Assessed up to 30 days after resection; Patients underwent resection of their pancreatic cancer up to 3 weeks after completion of chemoradiation therapy
