09-20-2024 Neoadjuvant Therapy
Scenario:
- Patient presented with Rectal Primary cT2 cN2a cM0 Stage 3B Grade 3 Adenocarcinoma
- Treatment Plan: Total neo-adjuvant therapy followed by consolidative proctocolectomy with perhaps formation of a permanent colostomy pending response to treatment
- Patient treated with Neoadjuvant Chemo/XRT
- After neoadjuvant therapy complete Flexible Sigmoidoscopy shows no visible cancer, biopsies negative. Scans show no evidence of viable disease, no adenopathy, no mets
- Med Onc-Because of the findings on flexible sigmoidoscopy and the biopsy results, patient appears to have a complete clinical response. This provides patient with 2 options. Option 1 is surveillance. This would mean performing a flexible sigmoidoscopy every 3 months with biopsy. Option 2 involves surgical resection. After careful consideration, the patient has elected to undergo serial examinations.
Question: How would you code the SSDI Neoadjuvant Therapy Clinical Response?
- 1 Complete clinical response (CR) (per managing/treating physician statement)
- 2 Partial clinical response (PR) (per managing/treating physician statement)
- 3 Progressive disease (PD) (per managing/treating physician statement)
- 4 Stable disease (SD) (per managing/treating physician statement)
- 5 No response (NR) (per managing/treating physician statement) Not stated as progressive disease (PD) or stable disease (SD)
- 6 Neoadjuvant therapy done, managing/treating physician interpretation not available, treatment response inferred from imaging, biomarkers, or yc stage
- 7 Complete clinical response based on biopsy results from a pathology report (per pathologist assessment)
- 8 Neoadjuvant therapy done, response not documented or unknown
- 9 Unknown if neoadjuvant therapy performed
Answer: 1 Complete clinical response (CR) (per managing/treating physician statement)
