Aims and objectives
Accordingly to the data of Kazakh Scientific Research Institute of Oncology and Radiology,
in Kazakhstan rectal carcinoma (RC) keeps the 8th position in cancer morbidity rate (4,5% or 8,2 cases per 100 000 of population),
and the 8th position in cancer-related mortality rate as well (4,7%) [1].
Despite the fact that these indexes are lower comparing with the similar data from developed countries (the forth most frequently diagnosed cancer,
and the second leading cause of cancer-related death [2,3]),
growing morbidity rate,
especially in population younger than 50 years old,
requires thorough management approach.
The role of high – resolution magnetic resonance imaging (MRI) in RC management has evolved greatly,
due to its ability to accurately evaluate the depth of tumor invasion,
mesorectal fascia and sphincter involvement.
Up to the current moment,
there are a lot of international scientific papers were published,
reporting accuracy rates for 3 tesla MRI systems in rectal cancer staging [4-8]. As tumor epidemiology,
phenotype,
frequency of different pathology subtypes can vary in different parts of the world,
we tried to summarize diagnostic accuracy and predictive value of 3T MRI in RC staging on Central Asia patients population.
The purposes of this study are (i) MR-imaging staging of rectal carcinoma and correlation with pathology results; (ii) assessment of the diagnostic accuracy and predictive power of 3 tesla MRI for extramural vascular invasion in RC.
