Magnetic resonance imaging for diagnosis and neoadjuvant treatment evaluation in locally advanced rectal cancer: A pictorial review
High-resolution pelvic magnetic resonance imaging (MRI) is the primary method for staging rectal cancer. MRI is highly accurate in the primary staging of rectal cancer; however, it has not proven to be effective in re-staging, especially in complete response evaluation after neoadjuvant therapy. Neoadjuvant chemoradiotherapy produces many changes in rectal tumors and on adjacent area, as a resu...
متن کاملQuantitative Aspects of Diffusion-weighted Magnetic Resonance Imaging in Rectal Cancer Response to Neoadjuvant Therapy
BACKGROUND The aim of the study was to evaluate the added value of the apparent diffusion coefficient (ADC) of diffusion-weighted magnetic resonance imaging (DW-MRI) in patients with rectal cancer who received neoadjuvant chemoradiotherapy (CRT). The use of DW-MRI for response evaluation in rectal cancer still remains a widely investigated issue, as the accurate detection of pathologic complete...
متن کاملCan diffusion-weighted MRI determine complete responders after neoadjuvant chemoradiation for locally advanced rectal cancer?
PURPOSE We aimed to prospectively determine if analyzing pre- and post-chemoradiotheraphy (CRT) changes in the signal intensity (SI) and apperent diffusion coefficient (ADC) values from diffusion-weighted magnetic resonance imaging (DW-MRI) can accurately predict complete responders for locally advanced rectal cancer. MATERIALS AND METHODS Thirty patients (mean age, 54.3 years) with locally a...
متن کاملNew drug in neoadjuvant chemoradiation for rectal cancer
Background: In recent years, neoadjuvant chemoradiation and subsequent surgical resection with total mesorectal excision has been shown to increase local control with decreased toxicity. Neoadjuvant chemoradiotherapy is the standard treatment for locally advanced rectal cancer. In this study we evaluated the efficacy a cox-2 inhibitor on pathologic response, sphincter preservation and acute tox...
متن کاملRole of Magnetic Resonance Imaging in Locally Advanced Rectal Cancer
This chapter will give an overview of the magnetic resonance imaging (MRI) modalities used in locally advanced rectal cancer (LARC) staging with an emphasis on the role of MRI and its significance for planning an effective therapeutic strategy for the individual patient. Specifically, the aim of this chapter is to present a brief review about: 1. Methodologies of Magnetic Resonance Imaging in L...
