Abstract

Tumour heterogeneity in metastatic gynaecological cancer and especially advanced ovarian cancer has been reported at the histological and genetic levels and found to be associated with adverse clinical outcomes. Classic tumour evaluation using standard CT or MRI techniques does not account for the intra- or inter-tumoural heterogeneity in advanced ovarian cancer with peritoneal carcinomatosis. As such, computational approaches in assessing tumour heterogeneity have been proposed using radiomics and radiogenomics to capitalise the whole tumour heterogeneity as opposed to single biopsy sampling. As part of radiomics, texture analysis which includes the extraction of multiple data from the images has been proposed recently to evaluate advanced ovarian tumour heterogeneity. The preliminary data suggests that it can unravel tumour heterogeneity and predict response to treatment both conventional and immunotherapy.
