1) If Hist_Type_2 is not 8510, 8832, 8930, or 9731, then skip ahead to step 2). Otherwise, continue with these site-specific updates and then skip ahead to step 4):
If Hist_Type_2 = 8510 then
If Site is thyroid (C739) then
Change Hist_Type_3 to 8345
Else
Change Hist_Type_3 to 8510
End-If
End-If
Change Hist_Behavior_3 to current Hist_Behavior_2 value
End-If.
If Hist_Type_2 = 8832 and Hist_Behavior_2 = 0 then
If Site is skin (C440-C449) then
Change Hist_Type_3 to 8832
Else
Change Hist_Type_3 to 8831
End-If
Change Hist_Behavior_3 to current Hist_Behavior_2 value
End-If.
If Hist_Type_2 = 8832 and Hist_Behavior_2 = 1 then
If Site is skin (C440-C449) then
Change Hist_Type_3 to 8832
Else
Change Hist_Type_3 to 8834
End-If
Change Hist_Behavior_3 to current Hist_Behavior_2 value
End-If.
If Hist_Type_2 = 8832 and Hist_Behavior_2 = 2 or 3 then
Change Hist_Type_3 to current Hist_Type_2 value
Change Hist_Behavior_3 to current Hist_Behavior_2 value
End-If.
If Hist_Type_2 = 8930 and Hist_Behavior_2 = 0 then
If Site is endometrium (C540-C549) then
Change Hist_Type_3 to 8930
Else
If Site is gastrointestinal (C150-C218) or
Site Is gastrointestinal other (C260-C269) then
Change Hist_Type_3 to 8936
Else
If Site is kidney (C649) then
Change Hist_Type_3 to 8966
Else
Change Hist_Type_3 to 8935
End-If
End-If
End-If
Change Hist_Behavior_3 to current Hist_Behavior_2 value
End-If.
If Hist_Type_2 = 8930 and Hist_Behavior_2 = 1, 2, or 3 then
If Site is endometrium (C540-C549) then
Change Hist_Type_3 to 8930
Else
If Site is gastrointestinal (C150-C218) or
Site Is gastrointestinal other (C260-C269) then
Change Hist_Type_3 to 8936

Change Hist_Type_3 to 8935
End-If
End-If
Change Hist_Behavior_3 to current Hist_Behavior_2 value
End-If.
If Hist_Type_2 = 9731 then
If Site is bones (C400-C419) then
Change Hist_Type_3 to 9731
Else
Change Hist_Type_3 to 9734
End-If
Change Hist_Behavior_3 to current Hist_Behavior_2 value
End-If.
2) Look up the Hist_Type_2/Hist_Behavior_2 combination in the ICDO2-ICDO3 Conversion Table. If a matching row is found, then convert Hist_Type_3 and Hist_Behavior_3 to the conversion values listed, and go on to step 4). If a matching row is not found, then go on to step 3).

3) (3,2,1,0), and go on to step 4). Otherwise,if a matching row is not found, then just convert Hist_Type_3 and Hist_Behavior_3 directly from Hist_Type_2 and Hist_Behavior_2 and go on to step 4).
4) Hist_Type_3 had been changed by any of the above procedures, then reset ICDO3_Conv_Flag to 1.
