ODS-C · Give each week a clear focus.

8 weeks · About 6 hours per week

Week 1

Cancer Registry Operations and Data Collection

  • Map every data item in the abstracting workflow to its source document, identifying which items come from the pathology report, which from the medical record, and which from the treating physician

  • Define casefinding criteria for reportable neoplasms and distinguish reportable from non-reportable diagnoses using benign, borderline, and in-situ examples

  • Practice extracting patient demographics, facility identifiers, and accession numbers from a sample abstracting packet without errors

  • Build a personal checklist for first-course versus subsequent-course documentation timing

Your checkpoint

A completed workflow map listing each abstracted data item, its source document, and its collection timing, plus a 20-case casefinding sorting exercise with written rationale for each include/exclude decision

Week 2

Cancer Registry Operations and Data Collection

  • Abstract primary site, histology, and behavior codes from pathology reports and reconcile conflicting reports using registry coding priority rules

  • Apply multiple-primary and histology-grouping rules to ambiguous case scenarios and justify each decision

  • Code treatment fields for surgery, radiation, systemic therapy, and immunotherapy from operative and oncology notes

  • Identify and correct common abstraction errors in a set of deliberately flawed sample abstracts

Your checkpoint

Ten fully abstracted practice cases with site, histology, behavior, and treatment fields completed and a written error log identifying every correction made to the flawed sample abstracts

Week 3

Cancer Diagnosis, Staging, and Treatment

  • Differentiate staging systems by purpose and describe when each is collected and reported

  • Assign T, N, M, stage group, and prognostic factors for solid tumors across several anatomic sites using provided clinical scenarios

  • Distinguish clinical from pathologic staging documentation and record the staging basis correctly

  • Explain the role of biomarkers and molecular markers in classification and staging for selected sites

Your checkpoint

A staging worksheet with twelve case scenarios staged end to end, including T/N/M, stage group, staging basis, and a one-line rationale for each assignment

Week 4

Cancer Diagnosis, Staging, and Treatment

  • Sequence first-course treatment modalities in the correct order and record treatment dates accurately

  • Interpret operative reports to distinguish definitive resection from biopsy and to capture surgical approach codes

  • Describe how radiation therapy fields, doses, and intent are documented and translated into registry fields

  • Summarize how systemic therapy regimens and clinical trial participation are recorded

Your checkpoint

A treatment abstraction packet of eight cases with first-course treatment fields completed and a comparison table showing how each modality's documentation translates into registry fields

Week 5

Cancer Registry Standards, Compliance, and Quality

  • Locate and apply the standards governing data quality, timeliness, and completeness to a mock facility audit

  • Define each data quality metric, calculate it from a provided case sample, and interpret whether the result meets a target threshold

  • Outline the components of a compliance plan covering confidentiality, access control, and audit trails

  • Describe the process for case reabstracting and reconciliation when quality review finds discrepancies

Your checkpoint

A mock quality audit report with completeness, timeliness, and accuracy rates calculated from a supplied case set, each rate compared to a target, and a corrective action list for every metric that falls short

Week 6

Cancer Registry Standards, Compliance, and Quality & Cancer Data Analysis, Research, and Public Health Reporting

  • Trace how registry data flow from case abstraction to central reporting and identify where validation edits occur

  • Interpret edit-check and validation failure messages and resolve representative errors

  • Apply confidentiality and data-release rules to hypothetical requests for registry data

  • Describe how follow-up activities and linkage to vital records support data completeness

Your checkpoint

A data-flow diagram from abstraction through central submission, annotated with the validation checkpoint at each stage, plus a written response to three hypothetical data-release requests citing the applicable confidentiality principle

Week 7

Cancer Data Analysis, Research, and Public Health Reporting

  • Calculate and interpret incidence, prevalence, age-adjusted rates, and survival statistics from a provided dataset

  • Select appropriate denominators and explain how population data affect rate calculations

  • Design a simple comparative analysis and identify confounding and bias risks in registry-based studies

  • Produce a table and figure appropriate for a public health report from the same dataset

Your checkpoint

A short analytic report containing at least three calculated measures with methodology notes, one table, one figure, and a paragraph on limitations and potential biases

Week 8

Cancer Registry Operations and Data Collection & Cancer Diagnosis, Staging, and Treatment & Cancer Registry Standards, Compliance, and Quality & Cancer Data Analysis, Research, and Public Health Reporting

  • Complete a full-length timed practice assessment and score performance by domain

  • Reabstract the weakest-performing case types until field-level accuracy improves

  • Consolidate error patterns into a one-page personal rule sheet for high-risk fields

  • Verify readiness by reviewing every domain's key standards and metrics one final time

Your checkpoint

A scored practice assessment with a domain-by-domain performance breakdown, a remediation log for every missed item, and a finalized one-page rule sheet of high-risk field decisions

Milestones

Week 2: Abstract ten practice cases end to end with site, histology, behavior, and treatment fields completed, and explain in writing why each case was or was not reportable

Week 4: Stage twelve scenarios correctly, including T/N/M, stage group, and staging basis, and correctly sequence first-course treatment for eight cases

Week 6: Calculate completeness, timeliness, and accuracy rates from a mock audit, state whether each meets its target, and resolve a set of validation edit failures

Week 8: Score at or above your target on a full-length timed practice assessment, with every missed item logged and remediated and a personal rule sheet completed
