CTR Abstracting & Coding

Question 1

What is the primary purpose of abstracting in a cancer registry?

Accepted Answer

To extract and code cancer data

Answer

Abstracting is the core process in a cancer registry where trained registrars review patient medical records to identify, extract, and code specific information related to a cancer diagnosis. This includes details about the tumor, patient demographics, treatment, and follow-up. The coded data forms the foundation for all registry analyses and reporting.

Question 2

Which coding system is used to classify tumor histology during abstracting?

Accepted Answer

ICD-O-3

Answer

The International Classification of Diseases for Oncology, Third Edition (ICD-O-3), is the standard coding system used worldwide for classifying the topography (site) and morphology (histology/behavior) of neoplasms. It is specifically designed for cancer registries to ensure consistent and detailed coding of tumor characteristics. Other options like ICD-10-CM, HCPCS, and CPT are used for billing and general medical diagnoses, not specific cancer histology.

Question 3

Which of the following is essential when coding the extent of disease in an abstract?

Accepted Answer

TNM staging system

Answer

The TNM (Tumor, Node, Metastasis) staging system is the internationally recognized standard for classifying the extent of cancer spread. It provides a precise and standardized way to describe the size of the primary tumor (T), the involvement of regional lymph nodes (N), and the presence or absence of distant metastasis (M). This system is critical for treatment planning, prognosis, and research.

Question 4

What information is typically abstracted in the 'first course of treatment' section?

Accepted Answer

Initial cancer-directed therapies

Answer

The 'first course of treatment' section in a cancer abstract documents the initial therapies administered to a patient specifically to treat their cancer. This typically includes surgery, radiation, chemotherapy, hormone therapy, or immunotherapy given within a defined period after diagnosis. This data is crucial for understanding initial treatment patterns and evaluating their effectiveness.

Question 5

What patient demographic detail is critical in cancer abstracting?

Accepted Answer

Patient demographic details

Answer

Patient demographic details, such as age, sex, race, ethnicity, and place of residence, are critical in cancer abstracting. This information allows for epidemiological analysis, helping to identify cancer incidence and survival disparities among different population groups. It is essential for public health planning and targeted interventions.
