What are tumor deposits in the context of colorectal cancer pathology?
Understand the Problem
The question is asking for clarification on what tumor deposits are specifically in relation to colorectal cancer pathology. It presents multiple-choice options that help in identifying the correct definition.
Answer
Tumor deposits in colorectal cancer are discontinuous tumor spread in the mesocolon or mesorectum, affecting 20% of patients and negatively impacting survival.
Tumor deposits in colorectal cancer are discontinuous aggregates of tumor cells found in the mesocolon or mesorectum, separate from the primary tumor. They are present in about 20% of cases and are associated with poorer prognosis.
Answer for screen readers
Tumor deposits in colorectal cancer are discontinuous aggregates of tumor cells found in the mesocolon or mesorectum, separate from the primary tumor. They are present in about 20% of cases and are associated with poorer prognosis.
More Information
Tumor deposits are considered significant because they indicate a more aggressive spread of cancer, which may not follow typical lymphatic pathways. This makes them crucial for accurate staging and prognosis.
Tips
Mistaking tumor deposits for lymph node involvement can misinterpret the stage of cancer. It is essential to correctly identify and classify these deposits for proper treatment planning.
