Inquiry Details
References:
2007 SEER Manual, C-1059. Appendix C
Question:
MPH rules--Rectum: How is the number of primaries to be determined when a treatment plan has been completed, but it is not possible to determine whether there was a disease-free interval between occurrences? See Discussion.
Discussion:
Patient diagnosed with adenocarcinoma of the rectum in March 2006, underwent chemo and radiation therapy as treatment. Patient seen in April 2007 for surveillance colonoscopy. HPI stated patient underwent chemorad with good results. Colonoscopy showed "persistent" disease. Abdominal perineal resection was done in May 2007. Path showed adenocarcinoma of the rectum.
Keeping in mind that we are not to use a clinical statement for determining recurrences, is the April 2007 occurrence counted as a new primary?
Answer:
For cases diagnosed 2007 or later:
Do not abstract the 2007 events as a new primary. "Persistent disease" indicates there was never a disease free interval.
