Follow-up Calculations
| Criteria | Calculation | Number | Percent |
|---|---|---|---|
| Total cases in registry since reference date | ________ | ||
| 1. less "benign" and "borderline" cases (behavior codes 0, 1) |
(-) | ________ | |
| 2. less carcinoma in situ cervix cases | (-) | ________ | |
| 3. less cases of in situ and localized basal and squamous cell carcinoma of skin | (-) | ________ | |
| 4. less foreign residents | (-) | ________ | |
| 5. less nonanalytic | (-) | ________ | |
| Subtotal cases = All analytic cases since reference date (class of case 0, 1, 2) | (A) | ________ | 100% |
| less number dead (or are 100 years old or older) | (B)- | ________ | ________ |
| Subtotal cases (number living) | (C) | ________ | ________ |
| less number current (known to be alive in the last 15 months) | (D)- | ________ | ________ |
| Total (Lost to Follow-Up or Not Current) | (E) | ________ | ________ |
| Follow-Up Rate | _______* |
Note:
Line A minus Line B equals Line C;
Line D plus Line E also equals Line C:
Line B plus Line D Plus Line E equals Line A.
or: A - B = C; D + E = C; B + D + E = A
To calculate percentages, divide lines B, C, D, and E by line A.
* An 80 percent follow-up rate is maintained for all analytic patients from the cancer registry reference date.
| Number | Percent | ||
|---|---|---|---|
| Total cases in registry from the last five years or since reference date, whichever is shorter | ________ | ||
| 1. less "benign" and "borderline" cases in last five years (behavior codes 0, 1 ) | (-) | ________ | |
| 2. less carcinoma in situ cervix cases | (-) | ________ | |
| 3. less cases of in situ and localized basal and squamous cell carcinoma of skin | (-) | ________ | |
| 4. less cases of in situ and localized basal and squamous cell carcinoma of skin | (-) | ________ | |
| 5. less nonanalytic | (-) | ________ | |
| Subtotal cases = All analytic cases in last five years or since reference date whichever is shorter | (A) | ________ | 100% |
| Less number dead (or are 100 years or older) | (B)- | ________ | |
| Subtotal cases (number living) | (C) | ________ | ________ |
| less number current (known to be alive in the last 15 months) | (D) | ________ | ________ |
| Total (Lost to Follow-Up or Not Current) | (E) | ________ | ________ |
| Follow-Up Rate | ______** |
Note:
Line A minus Line B equals Line C;
Line D plus Line E also equals Line C:
Line B plus Line D plus Line E equals Line A:
or: A-B=C; D+E=C;B+D+E=A
To calculate percentages, divide lines B, C, D, and E by line A.
** A 90 percent follow-up rate is maintained for all analytic patients diagnosed within the last five years or from the cancer registry reference date, whichever is shorter.
