Presentation Transcript

  1. AJCC Staging Moments AJCC TNM Staging 7th Edition Lung Case #3 • Contributors: • Valerie W. Rusch, MD Memorial Sloan-Kettering Cancer Center, New York, New York • Peter Goldstraw, MD Royal Brompton Hospital, London, England • Kelly J. Butnor, MD University of Vermont Medical Center, Burlington, Vermot • Thomas W. Rice, MD Cleveland Clinic, Cleveland, Ohio

  2. Lung Case # 3 Presentation of New Case • Newly diagnosed lung cancer patient • Presentation at Cancer Conference for treatment recommendations and clinical staging

  3. Lung Case # 3 History & Physical • 65 yr old female who presented with inappropriate behavior and thoughts • Current smoker, using nicotine patch to quit

  4. Lung Case # 3 Imaging Results • Chest x-ray- infiltrate • CT & MRI brain- 2cm mets in eachright frontal & right occipital lobes • CT chest- 2.4cm LUL lung mass, bilateral mediastinal nodes Used with permission. Schuchert M, Luketich J: Solitary Sites of Metastatic Disease in Non-Small Cell Lung Cancer. Current Treatment Options in Oncology. 4(1):65-79. Current Science, Inc.

  5. Lung Case # 3 Diagnostic Procedure • Procedure • CT guided biopsy LUL lung • Pathology Report • Adenocarcinoma

  6. Lung Case # 3 Clinical Staging • Clinical staging • Uses information from the physical exam, imaging, and diagnostic biopsy • Purpose • Select appropriate treatment • Estimate prognosis

  7. Lung Case # 3 Clinical Staging • Synopsis- patient with 2.4cm LUL lung mass, bilat mediastinal nodes, and brain mets • What is the clinical stage? • T____ • N____ • M____ • Stage Group______

  8. Lung Case # 3 Clinical Staging • Clinical Stage correct answer • T1b • N3 • M1b • Stage Group IV • Based on stage, treatment is selected • Review NCCN treatment guidelines for this stage

  9. Lung Case # 3 Clinical Staging • Rationale for staging choices • T1b for ca >2cm but <3cm • N3 because contralateral mediastinal nodes were clinically positive on imaging • M1b because distant metastases (brain) were found on imaging; if additional mets were suspected, appropriate tests would be performed before developing a treatment plan

  10. Prognostic Factors Clinically Significant • Applicable to this case • Separate tumor nodules: none • There are no prognostic factors required for staging

  11. Lung Case # 3 Presentation after Surgery • The procedure chosen based on the 2.4cm LUL lung mass, bilat mediastinal nodes, and brain mets, Stage IV, is resection of metastases • Presentation at Cancer Conference for adjuvant treatment recommendations and pathologic staging

  12. Lung Case # 3 Surgery & Findings • Procedure • Gross resection brain mets rt frontal and occipital lobes • Operative findings • No additional information

  13. Lung Case # 3 Pathology Results • Met adenocarcinoma in rt frontal and occipital lobes

  14. Lung Case # 3 Pathologic Staging • Pathologic staging • Uses information from the clinical staging supplemented or modified by information from surgery and the pathology report • Purpose • Additional precise data for estimating prognosis • Calculating end results (survival data)

  15. Lung Case # 3 Pathologic Staging • Synopsis- patient with 2.4cm LUL lung mass, bilat mediastinal nodes, brain mets • What is the pathologic stage? (remember, clinical M may be used in pathologic staging) • T____ • N____ • M____ • Stage Group______

  16. Lung Case # 3 Pathologic Staging • Pathologic Stage correct answer • pTX • pNX • pM1b • Stage Group IV • Based on pathologic stage, there is more information to estimate prognosis and adjuvant treatment is selected

  17. Lung Case # 3 Pathologic Staging • Rationale for staging choices • pTX because the primary tumor was not removed, pathologic staging cannot be completed • pNX because regional nodes were not removed, pathologic staging cannot be completed • pM1b because the brain mets were proven histologically

  18. Prognostic Factors Clinically Significant • Applicable to this case • Separate tumor nodules: none • There are no prognostic factors required for staging

  19. AJCC Cancer Staging Atlas N3 Contralateral mediastinal or hilar; ipsilat/contralat scalene; supraclavicular LN

  20. Lung Case # 3 Recap of Staging • Summary of correct answers • Clinical stage T1b N3 M1b Stage Group IV • Pathologic stage TX NX M1b Stage Group IV • The staging classifications have a different purpose and therefore can be different. Do not go back and change the clinical staging based on pathologic staging information.

  21. Staging Moments Summary • Review site-specific information if needed • Clinical Staging • Based on information before treatment • Used to select treatment options • Pathologic Staging • Based on clinical data PLUS surgery and pathology report information • Used to evaluate end-results (survival)
