[Prognostic factors and functional imaging in rectal cancer]

Area of Science:

• Oncology
• Radiology
• Surgical Oncology

Context:

• Rectal cancer treatment outcomes have improved due to surgical and neoadjuvant therapy advancements.
• Total mesorectal excision (TME) and preoperative radiochemotherapy have significantly enhanced patient prognosis.
• The need for precise prognostic factor identification in rectal tumors, pre- and post-treatment, is crucial for personalized care.

Purpose:

• To highlight the evolving role of imaging in defining prognostic factors for rectal tumors.
• To emphasize the necessity of tailored treatment strategies based on individual tumor characteristics.
• To underscore the contribution of advanced imaging techniques to rectal cancer management.

Summary:

• Modern rectal cancer management integrates surgical innovations like total mesorectal excision with neoadjuvant therapies.
• Imaging studies are increasingly vital for identifying prognostic factors before and after neoadjuvant treatment, enabling personalized therapeutic decisions.
• Functional and molecular imaging techniques offer in vivo insights into tumor characteristics such as angiogenesis, metabolism, and cellularity.

Impact:

• Improved patient stratification and treatment planning for rectal cancer.
• Enhanced ability to evaluate treatment response and tailor therapies.
• Advancement of precision medicine in rectal cancer care through integrated imaging and clinical data.
