Neoadjuvant Accelerated Short Course Radiation Therapy With Photons and Capecitabine for Resectable Pancreatic Cancer

12 de abril de 2018 actualizado por: Harvey Mamon, MD, PhD, Dana-Farber Cancer Institute

Phase I/II Study of Neoadjuvant Accelerated Short Course Radiation Therapy With Photons and Capecitabine for Resectable Pancreatic Cancer

The purpose of this research study is to determine if it is possible to deliver high dose radiation in one week while also giving the drug capecitabine for the treatment of pancreatic cancer prior to surgery, to determine if this treatment can be given safely for the treatment of pancreatic cancer prior to surgery and, to determine if this treatment can improve the local control pancreatic cancer prior to surgery compared to historical controls of standard treatment.

Medidas de resultado primarias

Medida de resultado
Medida Descripción
Periodo de tiempo
Neoadjuvant Short-Course Photon Radiation Therapy Maximum Tolerated Dose (MTD) [Phase I]
Periodo de tiempo: 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.
within 3 weeks of the start of chemoradiation therapy
Dose Limiting Toxicity (DLT) [Phase I]
Periodo de tiempo: 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.
within 3 weeks of the start of chemoradiation therapy
Grade 3-5 Toxicity Rate [Phase II]
Periodo de tiempo: within 3 weeks of the start of chemoradiation therapy
All Grade 3-5 events based on CTCAEv3 related to the accelerated dose (attribution possible, probable, definite) as reported on case report forms.
within 3 weeks of the start of chemoradiation therapy

Periodo de tiempo
Local Recurrence Rate [Phase II]
Periodo de tiempo: 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]
Periodo de tiempo: 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]
Periodo de tiempo: 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]
Periodo de tiempo: 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]
Periodo de tiempo: 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
