Pancreatic Adenocarcinoma Clinical Trial
Official title:
DP-IMRT Pancreas: A Non-randomised Phase I/II Study of Dose-escalated Hypofractionated Dose-Painted Intensity Modulated Radiotherapy (DPIMRT) in Resectable/Borderline Resectable Pancreatic Adenocarcinoma
This is a prospective non-randomised Phase I/II Radiotherapy (RT) study with patients recruited to escalated dose cohorts. Patients with resectable or borderline resectable (per the National Comprehensive Cancer Network (NCCN) criteria) pancreatic adenocarcinoma will receive dose-escalated hypofractionated DP-IMRT via Intensity Modulated Radiotherapy (IMRT) / Volume Modulated Arc Therapy (VMAT).

Previous thoracic or abdominal or pelvic radiation therapy (RT) 2. Previous treatment for bilirubin regression, other than stenting 3. Known co-existing or prior malignancy within the last 5 years (except for Basal Cell Carcinoma (BCC) or Squamous Cell Carcinoma (SCC) of the skin) which is likely to interfere with treatment or assessment of outcomes 4. Syndromes or conditions associated with increased radiosensitivity 5. Uncontrolled intercurrent illness that is likely to interfere with treatment or assessment of outcomes, or psychiatric illness/ social situations that would limit compliance with study requirements 6. Evidence of any other significant clinical disorder or laboratory findings that makes it undesirable for the patient to participate in the study, or if it is felt by the research/ Medical team that the patient may not be able to comply with the protocol and follow up schedule due to psychological, familial, sociological or geographical conditions |

Primary | Phase 1 - to establish the MTD in a dose-escalated and hypofractionated RT regime delivered via IMRT/VMAT by the number of DLTs | To establish the MTD in a dose-escalated and hypofractionated RT regime delivered via IMRT/VMAT by the number of DLTs, and the rate of patient withdrawal from trial treatment due to DLTs. Analysis will be performed for each cohort after all patients have been assessed for their 4-week post RT assessment. | 4 weeks | |
Primary | Phase 2 - to determine the frequency and severity of DLTs due to AE/Toxicity meeting definition of DLT at 4 weeks post RT | The rate of DLTs up to 4 weeks post RT will be calculated. This proportion along with the 90% confidence intervals will be reported. | 4 weeks | |
Primary | Phase 2 - to determine the rate of patient withdrawal from trial treatment due to AE/Toxicity meeting definition of DLT at 4 weeks post RT | The rate of withdrawal from trial treatment of patients due to DLTs will be calculated. This proportion along with the 90% Confidence Interval will be reported. Other toxicity data including SAEs will be summarised and presented in tabular format with proportions plus 95% Confidence Interval where appropriate. | 4 weeks | |
Secondary | To quantify the percentage of histologically proven R0 resections in the trial patient group (R0 to be defined as a minimal clearance of at least1 mm). | The percentage of histologically proven R0 resections in this patient group (R0 to be defined as a minimal clearance of at least 1 mm) will be presented with 95% Confidence Interval. | 2 years | |
Secondary | To determine the rate of failure to progress to surgery due to disease progression during neoadjuvant radiotherapy, and conversely the proportion of patients who do receive surgical resection | The rate of failure to progress to surgery due to disease progression during neoadjuvant radiotherapy will be presented with 95% Confidence Interval. The rate of progression to surgery will be presented with 95% CI. The proportion of patients who receive surgical resection overall will be presented with 95% Confidence Interval. | 2 years | |
Secondary | To document the proportion of peri-operative complications | The proportion of patients with peri-operative complications will be presented with 95% Confidence Interval. | 2 years | |
Secondary | To evaluate the impact of treatment on OS, overall and by resectability (whether resectable or borderline resectable) | The Kaplan-Meier method will be used to estimate OS. This will be expressed as median survival with 95% Confidence Interval and will be analysed after patients have been followed for two years after completion of study treatment. The Log-rank test will be used to compare differences in survival between resectable and borderline resectable patients. | 2 years | |
Secondary | To evaluate the impact of treatment on PFS, overall and by resectability (whether resectable or borderline resectable) | The Kaplan-Meier method will be used to estimate PFS. This will be expressed as median survival with 95% Confidence Interval and will be analysed after patients have been followed for two years after completion of study treatment. The Log-rank test will be used to compare differences in survival between resectable and borderline resectable patients. | 2 years | |
Secondary | To evaluate tumour response on surgically resected patients using resected specimens | The proportion of surgically resected patients receiving at least 14 fractions of RT with tumour response using the resected specimens will be presented with 95% Confidence Interval. | 2 years | |
Secondary | To evaluate Quality of Life | The mean (and standard deviation) of the overall and domain specific European Organisation for Research and Treatment for Cancer (EORTC) Quality Life Questionnaire (QLQ) C30 scores at each time point will be reported (pre-chemotherapy, pre-RT, pre-surgery, 6-, 12- and 24-months post RT).
The EORTC QLQ C30 questionnaire has five functioning subscale scores and nine symptoms subscale scores. Minimum value = 0; Max value = 100 Function Scales: Higher numbers mean better function Symptom Scale: Higher numbers mean more symptoms |

Secondary | To evaluate Quality of Life | The mean (and standard deviation) of the overall and domain specific European Organisation for Research and Treatment for Cancer (EORTC) Quality Life Questionnaire (QLQ) PAN 26 scores at each time point will be reported (pre-chemotherapy, pre-RT, pre-surgery, 6-, 12- and 24-months post RT).
The EOTRC QLQ PAN 26 questionnaire is a tumour specific quality of life questionnaire for patients with pancreatic cancer. Minimum value = 0; Max value = 100 Function Scales: Higher numbers mean better function Symptom Scale: Higher numbers mean more symptoms |
2 years | |
Secondary | To evaluate the incidence of late GI toxicities in patients who do not undergo surgical resection | The incidence of late toxicity at 6-, 12- and 24-months post-RT, in patients who do not undergo surgical resection, will be calculated, summarised and presented in tabular format with proportions plus 95% Confidence Interval where appropriate. Toxicities of = Grade 2 are of specific interest. Counts and frequencies will be provided for the worst grade AE experienced | 2 years |
