About

Background of the study: The accurate assessment of local cervical cancer spread (i.e. invasion) is of clinical importance for staging and treatment considerations. For example, if parametrial invasion is absent, radical surgery is the treatment of choice for tumors less than 4cm in diameter. However, if such invasion is present, the patient has become inoperable and (chemo)radiotherapy is warranted. Unfortunately, regular 1.5T MRI as a part of staging work-up has a limited accuracy for detecting loco-regional tumor invasion. Due to relatively frequent false-negative findings a risk of understaging and under-treatment occurs. For such cases adjuvant treatments with (chemo)radiotherapy are indicated after the initial surgery, causing increased morbidity and treatment associated risks. For higher stages, with primary (chemo)radiotherapy, a more reliable MRI based delineation of local tumor spread could enable individualized dose(volume) and field modifications.

Hypothesis/aim of the study: To develop and in vivo optimize T2w ultra high field (7T) MRI sequences, which use a combination of an endorectal and external coil, to image the (para)cervical area for assessment of the loco-regional tumor status in cervical cancer.

Study design: The proposed study is an investigator initiated, single center, prospective pilotstudy.

Study population: 20 patients with histological proven cervical cancer stage IB1, IB2, IIA of IIB will be included.

Primary study parameters/outcome of the study: Optimized T2w ultra high field (7T) MRI sequences of the (para)cervical area which allow qualitative assessment of the loco-regional invasion of cervical cancer.
