20170027 | MP/H Rules/Multiple primaries--Melanoma: Is a melanoma with an unknown laterality a different laterality for the purposes of applying Multiple Primaries/Histology Rule M4? See Discussion. |
8/1/2016 Left Abdomen biopsy: Early melanoma in situ (C445-2, 8720/2). 9/2/2016 Upper back: Superficially invasive malignant melanoma (C445-9, 8720/3). Does rule M4 apply and multiple primaries should be reported or does rule M8 apply and a single primary should be reported? |
Abstract multiple primaries following Multiple Primary Rule M4. Unknown laterality is a different laterality for the purposes of applying the MP/H rules for melanoma. NOTE: This answer applies to cases diagnosed prior to 2018. As of 1/1/2018, early melanoma is not reportable. |

20200020 | Reportability/Brain and CNS--Pituitary: Can a clinical diagnosis of pituitary adenoma be accessioned based on imaging if treatment is not given and subsequent imaging years later shows no evidence of pituitary adenoma? See Discussion. |
The patient was clinically diagnosed with a pituitary adenoma on MRI in June 2009. The MRI noted an unusual contour involving the superior margin of the pituitary gland and the clinical interpretation was a small pituitary adenoma. The patient did not follow-up with the recommended repeat imaging and never received treatment for the pituitary adenoma. The patient was eventually seen again in January 2020 and the MRI showed no adenoma in the pituitary gland. Since pituitary adenomas are known to spontaneously regress, should the 2009 diagnosis of pituitary adenoma be accessioned as a SEER reportable benign central nervous system (CNS) tumor? |
Pituitary adenoma is reportable even if it later regresses without treatment. Use text fields to record the details of this case. |

20031111 | EOD-Extension--Lung: For a left upper lobe lung tumor that extends across the fissure into the left lower lobe, should this field be coded to 10 [Tumor confined to one lung] or 77 [Separate tumor nodules in different lobe]? | For cases diagnosed 1998-2003: Assign EOD extension code 10 [Tumor confined to one lung]. EOD extension code 10 applies to a single tumor within one lung, even one that crosses over a fissure into another lobe. EOD extension code 10 is not correct if the tumor extends to the pleura, or if there is atelectasis, obstructive pneumonitis or malignant pleural effusion. Code 77 is incorrect because that is a separate tumor nodule in a different lobe. | Lung | N/A | 2003 | |

20170036 | Grade--Prostate: How are the prostate-related fields completed when documentation in pathology reports only includes one of the new grade groups? See Discussion. |
Our pathologists have starting to use a new prostate cancer grading system that was adopted by WHO in 2016. The new grading scheme correlates with the prior Gleason grading scheme as follows: Grade Group 1 = Gleason score 6 or less Grade Group 2 = Gleason score 3+4=7 Grade Group 3 = Gleason score 4+3 = 7 Grade Group 4 = Gleason score 8 Grade Group 5 = Gleason score 9-10 Our pathologists are no longer dictating the Gleason Primary and Secondary Pattern values nor the Gleason's Score. Reverse correlation from the new grade groups to the required patterns and score are difficult with Grade Groups 2 and 3 needing to be distinguished from one another and Grade Group 5 including two unique scores. The prostate-related fields include: Collaborative Site Specific Factor 7: Gleason's Primary Pattern and Secondary Pattern Values on Needle Core Biopsy/TURP Collaborative Site Specific Factor 8: Gleason's Score On Needle Core Biopsy/TURP Collaborative Site Specific Factor 9: Gleason's Primary Pattern and Secondary Pattern Values on Prostatectomy/Autopsy Collaborative Site Specific Factor 10: Gleason's Score on Prostatectomy/Autopsy |
When all you have is the grade group, you may use the following table to convert the Prostate Grade Groups to the appropriate code for the indicated fields. Grade Group Gleason Score Gleason Pattern SSF7 SSF8 SSF9 SSF10 Grade/diff Grade Group 1 6 or less <=3+3 099 999 099 999 1 Grade Group 2 7 3+4 034 007 034 007 2 Grade Group 3 7 4+3 043 007 043 007 2 Grade Group 4 8 4+4, 3+5, 5+3 999 999 999 999 3 Grade Group 5 9-10 4+5, 5+4, 5+5 099 999 099 999 3 |

20031119 | EOD-Extension/EOD-Lymph Nodes--Colon: For this primary, under which field are satellite tumor nodules in mesenteric adipose tissue coded? See Description. | Sigmoid colon, low anterior resection: Invasive adenocarcinoma, 5.5 cm greastest dimension, moderately differentiated. Tumor invades through muscularis propria, into mesenteric adipose tissue. No penetration of visceral peritoneum. Proximal, distal, and radial margins free of tumor. Satellite tumor nodule present within mesenteric adipose tissue, 1.5 cm diameter, located 2.8 cm from main bowel wall tumor. Ten lymph nodes identified, with no evidence of metastatic tumor.
Comment: The satellite tumor nodule present within the mesenteric adipose tissue has an infiltrating, irregular contoured appearance and does not appear to represent a previously replaced lymph node. This appears to be a local metastasis with histologic features most commonly associated with venous invasion (see AJCC Cancer Staging Handbook, Sixth Edition, 2002, page 131 for current staging terminology). |
For cases diagnosed 1998-2003: For EOD, each grossly detectable nodule in the regional mesenteric fat is counted as one regional lymph node. | Colon | N/A | 2003 |

20170051 | Reportability--Liver: Is intraductal papillary mucinous neoplasm (IPMN) of the liver a reportable diagnosis? See Discussion. |
Pathology shows: Right liver lobe, partial hepatectomy " intraductal papillary neoplasm with high grade dysplasia. |
Intraductal papillary mucinous neoplasm (IPMN) of the liver with high grade dysplasia is reportable. While most IPMNs arise from the pancreas, there exists a subset of IPMN of the biliary tract (BT-IPMN). Code as 8453/2. For more details, see the Reportability section of the SEER manual, https://seer.cancer.gov/manuals/2016/SPCSM_2016_maindoc.pdf |

20170054 | MP/H Rules/Multiple primaries--Brain and CNS: How many primaries should be abstracted for a patient with a 2011 diagnosis of oligodendroglioma followed by biopsy of tumor which demonstrated progression in 2016 with pathology report Final Diagnosis indicating WHO grade III anaplastic astrocytoma? See Discussion. |
The clinical documentation clearly identifies residual tumor after the 2011 craniotomy. Scans demonstrated slow enlargement of the tumor over the years, which resulted in a repeat craniotomy. The pathologist noted in the diagnosis comment section of the pathology report that Is this a single primary per MP/H Rule M3 (A single tumor is always a single primary), or an additional brain malignancy per MP/H Rule M8 (Tumors with ICD-O-3 histology codes on different branches in Chart 1 or Chart 2 are multiple primaries)? |
Based on the information provided, this is a single primary. The 2011 tumor was not completely removed and progressed over the years. MP/H Rule M3 for malignant brain cancer applies. Do not change the original histology code. Use text fields to document the later histologic type of anaplastic astrocytoma, WHO grade III. |

20041019 | EOD-Extension--Lung: Is this field coded to 10 [tumor confined to one lung] or 20 [Tumor involving main stem bronchus >= 2 cm from carina] when there is no mention of the mainstem bronchus and a lobectomy is performed? See Discussion. | The clinical work-up shows a mass at the left medial apex extending into the left lung. No mention of the main stem bronchus. Because a lobectomy was performed, we assume, per Note 2, that the tumor was greater than or equal to 2 cm from the carina. | For cases diagnosed 1998-2003: Code the EOD-Extension field to 10 [tumor confined to one lung] for the case example. The EOD-Extension code 20 [Tumor involving main stem bronchus >= 2 cm from carina] applies to tumors involving the main stem bronchus. | Lung | N/A | 2004 |

20140088 | Reportability--GIST: The 2014 SEER Program Coding and Staging Manual and the answer to SINQ 20100014 appear to conflict with respect to reporting GIST cases. The manual states (p.5, exception 1) that we are to accession the case if the patient is treated for cancer. However, the patient in Example #7 in the SINQ discussion is receiving chemotherapy, but is deemed not reportable. This is a problematic issue in our area, as pathologists prefer using the NCCN “Risk Stratification of Primary GIST by Mitotic Index, Size and Site” table rather than stating whether the tumor is benign or malignant. Although they tell us that moderate or high risk should receive treatment, they will not characterize them as malignant. |
Determining reportability for GIST is problematic because of the reluctance of pathologists to use the term "malignant" for GIST cases. If you can document the pathologist's terminology and case characteristics (e.g. treatment) that correspond to "malignant" for your registry as part of the registry's policies and procedures, you can report those cases as malignant.
The exception cited above in the SEER manual pertains to a clinical diagnosis with a negative pathology report. Normally, the negative pathology report would override the clinical diagnosis and the case would not be reportable. However, if the patient is treated for a malignancy in spite of the negative pathology, report the case.

20110072 | Multiplicity Counter/Date Multiple Tumors--Bladder: How are these fields coded when multiple tumors were present at the time of diagnosis and another tumor diagnosed a year later is determined to be the same primary? See Discussion. | In November 2007, a nephroureterectomy showed an invasive TCC of the renal pelvis and a separate in situ TCC of the ureter. The Multiplicity Counter field is coded 02 and the Date Multiple Tumors is coded to November 2007. In December 2008, an in situ bladder tumor is found. Are the multiplicity fields to be updated to reflect the new bladder tumor? | Multiplicity Counter field was initially coded 02. Change the code to 03 because the subsequent, additional tumor was determined to be the same primary. Update the Multiplicity Counter field only once. If additional tumors are determined to be the same primary for this case, it is not necessary to update this field again.
Date of Multiple Tumors field was initially coded November 2007. Multiple tumors were present at the time of the initial diagnosis. Do not change the date of this field when additional tumors are subsequently diagnosed. This data item reflects the earliest date that multiple tumors were present. See example 2 under #3 on page 81 of the 2010 SEER manual. |
