  • 2018 SEER Advanced Topics for Registry Professionals Workshop
    May 24th & 25th, 2018
    Following the NCRA Annual Educational Conference
    Sheraton New Orleans Hotel, New Orleans, LA
  • Revised Coding Instructions for 2017 (January 4, 2017)
  • Revised Solid Tumor Manual (MP/H) delayed until after January 1, 2018
    • In order to ensure the revised MP/H rules incorporate newly recommended ICD-O-3 histology terms and codes, the cancer registry community represented by the National Cancer Institute (NCI-SEER), Centers for Disease Control and Prevention (CDC), the National Cancer Data Base (NCDB), the American Joint Committee on Cancer (AJCC), and the Commission on Cancer (CoC), made the decision to delay the implementation of the revised Solid Tumor (MP/H) manual until after January 1, 2018.
