Status Final References Source 1: 2007 SEER Manual pgs: C-528 Notes: Appendix C Source 2: pgs: Notes: Question MP/H Rules--Lung: Per rule M8, tumors of the same site (left lung), same histology (NSCC), greater than 3 yrs apart are separate primaries. However, there was a recurrence to mediastinal LNs after 2 years. Would that make a difference as to whether the 2008 left lung carcinoma is reportable as a new primary or not? Please see discussion. Discussion Scenario: NSCC 2004 LLL with positive hilar/mediastinal LNs treated with LLL lobectomy, chemo and rad. 2006 per CT/PET recurrence in mediastinal LNs treated with chemoradiation. 2008 left lung nodule positive for NSCC stated by MD to be recurrence from 2004 (2008 path not compared to 2004 path). Answer The 2008 lung carcinoma is a separate primary according to rule M8. The 2006 diagnosis is metastases to the lymph nodes. Do not apply the MP/H rules to metastases.
