Documented in FORDS, page 13, and SEER PCSM, page 93
Some cancers, including colon, rectosigmoid junction, and rectum, may be graded using a two-grade system. If the grade is described as low grade or grade 1 of 2 (1/2), assign code 2. If the grade is described as high grade or grade 2 of 2 (2/2), assign code 4. The conversion table for a two-grade system is found in FORDS, page 13, and SEER Program Coding and Staging Manual, page 93.
