CTR Abstracting & Coding 1 — Questions and Answers
Question 1: What is the primary purpose of abstracting in a cancer registry?
- To analyze tumor registry finances
- To generate treatment protocols
- To extract and code cancer data (Correct answer)
- To validate patient insurance details
Correct answer: To extract and code cancer data
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?
- ICD-10-CM
- ICD-O-3 (Correct answer)
- HCPCS
- CPT
Correct answer: ICD-O-3
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?
- TNM staging system (Correct answer)
- Diagnosis-Related Group (DRG)
- Clinical Procedure Code
- Hospital billing record
Correct answer: TNM staging system
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?
- All treatments given throughout life
- Only experimental therapies
- Initial cancer-directed therapies (Correct answer)
- Treatments unrelated to the diagnosis
Correct answer: Initial cancer-directed therapies
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?
- Employment history
- Dietary habits
- Patient demographic details (Correct answer)
- Vaccination records
Correct answer: Patient demographic details
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.
Question 6: When should the abstract be completed after diagnosis in most registries?
- Within 1 year
- Within 30 days
- Within 6 months (Correct answer)
- After treatment ends
Correct answer: Within 6 months
Most cancer registries, particularly those accredited by the CoC, require abstracts to be completed within a specific timeframe after the date of diagnosis. A common standard is within six months to ensure timely data collection and reporting. This allows for prompt analysis and contribution to national databases, supporting current research and quality initiatives.
