radiofrequency ablation (RFA)

Richard van Hillegersberg, Professor

The purpose of the study is to determine the safety of radiofrequency ablation of locally advanced pancreatic cancer that can not be surgically removed with the current standard procedures. Complications after the operation will be registered. Moreover a pain score will be determined, length of hospital stay, chemotherapy, survival, progression free survival and a tumour marker.

Pancreatic cancer is the fourth leading cause of cancer related death in the Western world. At time of diagnosis, 20% of patients present with a resectable tumour, 40% with an irresectable locally advanced tumour (without metastases) and 40% with metastatic disease. The median survival of patients with irresectable locally advanced pancreatic cancer is only 6 months. Currently, there is no effective treatment for these patients. Therefore, there is an urgent need for new therapies. Radiofrequency ablation (RFA) is a technique that has been demonstrated to be effective in the treatment of several irresectable tumours. RFA produces local tumour destruction through high frequency alternating current flowing from an electrode implanted directly into the tumour and causing frictional heating. The purpose of this study is to determine the safety of RFA-pancreas in patients with non-metastasized, irresectable, locally advanced pancreatic cancer.

Safety Study of Radiofrequency Ablation of Locally Advanced Pancreatic Cancer

Phase II Study: Radiofrequency Ablation of Locally Advanced Pancreatic Cancer

The safety will be specified as the percentage of patients with complications directly related to RFA and the routinely performed double-bypass procedure, requiring re-intervention (i.e. endoscopy, radiology, or surgery). This is also known as a complication of grade III or higher in the Clavien-Dindo classification (internationally accepted classification for surgical complications). Moreover all in-hospital complications or complications developed within 30 days after the RFA procedure will be evaluated according to the Clavien-Dindo classification.

Type, frequency, dosage and duration of chemotherapy will be registered.

Concurrent chemoradiation therapy without panitumumab

C.M.L. van Herpen, Md PhD

For esophageal cancer that can not be removed by surgery, the choice of treatment is a combination of chemotherapy and radiotherapy. We call this combination- (or concurrent) chemoradiotherapy. Chemotherapy is treatment with drugs that kill cancer cells. Both chemotherapy and radiotherapy make the tumour smaller and enhance each other's effect. The goal of treatment with chemotherapy and radiation therapy is to cure the cancer. Unfortunately only a small proportion of patients are cured with this treatment.

Improvements in the outcome of treatment may be expected by using the so-called "targeted" treatments. With esophageal cancer, a protein (the epidermal growth factor receptor (this is a kind of trap), the EGFR), is present in many tumours. This protein causes the tumor to grow. Panitumumab is a drug that blocks the functioning of this receptor (catcher), so that possibly the growth and spread of esophageal cancer is prevented.

The main objective of this trial is to see if survival of patients with inoperable esophageal cancer improves as panitumumab is added to standard treatment with chemoradiotherapy.

It will also investigate whether patients tolerate the addition of panitumumab to the standard treatment. Also, the biological characteristics of the tumor will be examined. In a proportion of patients it will be determined how the enhancement of the cancer is visible on an FDG-PET scan before the start of treatment and how this changes during the treatment. It will be also be evaluated how this treatment affects the survival.

A complete response rate of approximately 30% is achieved for standard treatment of irresectable carcinoma of the oesophagus, consisting of concurrent chemoradiation therapy (50.5 Gy + cisplatin/5-FU). Attempts to improve outcome by intensifying conventional cytotoxic drugs or increasing the radiation dose have not been successful. Future improvements will likely require the incorporation of targeted agents that probably will not add significant toxicity, the use of molecular predictors of response and early identification of responders. In both squamous cell carcinoma and adenocarcinoma of the oesophagus expression of EGFR is correlated with poor outcome. Furthermore the addition of cetuximab, a chimaeric EGFR antibody, to radiation therapy in head and neck cancer and non-small cell lung cancer showed a gain in overall survival. In head and neck cancer studies with the addition of panitumumab to chemo-radiation therapy are currently ongoing. Therefore, we propose to perform a randomised phase II study of chemo-radiation therapy with or without the combination of panitumumab (human EGFR antibody) in irresectable squamous cell carcinoma or adenocarcinoma of the oesophagus without distant metastases.

A Randomised Phase II Study of Radio-chemotherapy With or Without Panitumumab (Vectibix®) in Irresectable Squamous Cell Carcinoma or Adenocarcinoma of the Oesophagus

To describe the 1-year OS rate after concurrent CRT with or without panitumumab in irresectable carcinoma of the oesophagus. The control arm is used to validate whether the historical cohort used for comparison is similar to our success-rate.

Investigation of the acute and long-term toxicity of both study arms (according to Common Terminology Criteria for Adverse Events (CTCAE) version 3.0);

PFS: interval between randomisation date and the date at which disease progression is established being not suspicious for a second cancer (histologically confirmed when in doubt) or date of death from any cause but clearly not related to disease- or treatment (e.g. accident). Patients still disease-free after 18 months follow-up or lost to follow-up or death clearly not related to disease or treatment (e.g. accident)), are censored at the date of the most recent follow-up or at the analysis cut-off date, whichever comes first.

Response rate: partial (PR) or complete response (CR) according to RECIST 1.1 at 3 months after treatment
