详细说明
The incidence of rectal cancer in the European Union is approximately 125 000 per year, constituting a third of the total colorectal cancer incidence(1). In Sweden approximately 2000 individuals are diagnosed with rectal cancer each year. Evaluation of patients and possible treatment strategies (including neo-adjuvant chemo/radiotherapy, choice of surgical technique and adjuvant chemotherapy) are based on tumor specific characteristics together with patient factors such as general condition and comorbidity. These characteristics include tumor, lymph node and metastasis classification (cTNM), height of tumor (distance from anal verge), engagement of circumferential margin or mesorectal fascia, signs of extramural invasion and the presence of distant metastases. Clinical examination and endoscopy together with magnetic resonance imaging (MRI) of the pelvic region are essential in the local staging process, where MRI provides the most accurate radiological assessment, especially for rectal tumors in stage T3 and T4. The recommended methods regarding evaluation of metastases (M stage) include contrast enhanced computed tomography (CT) or MRI of the liver/abdomen, CT of the thorax, and in selected cases positron emission tomography (PET)- CT, if extensive extramural vascular invasion is present.
Previous studies have investigated the efficiency of MRI compared to other radiological methods and found that MRI of the liver is superior to contrast enhanced CT, in terms of specificity and sensitivity for diagnosis of liver metastasis (both per patient and per lesion).
Even though MRI has been recommended as the first line modality for evaluating colorectal cancer liver metastases in patients who have not previously undergone therapy the Swedish national guidelines, as well as the European Society for Medical Oncology (ESMO), include recommendations of single venous phased contrast enhanced CT of the liver/abdomen in the pre-treatment radiological workup. Progress within diagnostics has led to development of CT examination with an additional 3 min equilibrium phase of the liver that may be added to the single venous phase in order to increase the sensitivity and specificity of the diagnosis of liver metastases. However, this has not yet been included in guidelines nor implemented on a national basis in the pre-treatment radiological workup in patients with colorectal cancer.
Objective The primary objective of the present study is to compare percentage of patients requiring further radiological examinations after index examination (due to inconclusive results) between patients randomized to an abbreviated MRI liver protocol and patients randomized to a combined single venous phase CT with an additional 3 min equilibrium phase of the liver. A secondary aim is to compare time to treatment initiation, survival and development of liver metatstases between patients randomized to either an abbreviated MRI or a combined single-venous phase CT with an additional 3 min equilibrium phase of the liver.
The study is a multicentre randomized controlled trial where the hypothesis is that there is no clinical difference between the two groups, and the study is designed as a non inferiority trial.

实验性的:MRI group
An abbreviated MRI of the liver/abdomen
|
The MRI examinations of the liver/abdomen will be performed at the same time as the pelvic MRI. A 1,5 T scanner will be used together with a dedicated torso/abdominal coil. An abbreviated MRI liver protocol includes 3 different sequences as follows:
|
有源比较器:CT group
A combined single venous and 3 min equilibrium phase CT of the abdomen/liver
|
The CT examination of the liver will be performed as a combined examination in a single venous phase starting with the thoracic region directly followed by the abdomen down to the pelvis.
An additional 3 min equilibrium phase of the liver only will end the examination.
Regular iodinated low-osmolar non-ionic contrast media will be used of 350 mg I/ml using a power injector, 2-4 ml/s, 100-150 ml dependent on patient weight and kidney function.
Reconstructed images in axial, coronal and sagittal plane will be performed.

Need for supplementary radiologic liver examination

Number of patients in need for supplementary radiologic liver examination/s before treatment decision, after index examination (CT or MRI) of the abdominal organs, due to inconclusive results.

Cost effectiveness
大体时间:12 months

Costs related to all index radiological examinations will be included.
Costs will be collected from national sources such as the Swedish association of local authorities and regions (SKR - Sveriges kommuner och regioner) whenever possible and alternatively from Sahlgrenska university hospital cost-per-patient files.
Possibly a more complex model will be relevant depending on outcome, where total health care costs are compared between the two radiological work-up routines.
Such an analysis will take survival into account.
