20091081 | Reportability/Histology--Brain and CNS: Is an "inflammatory myofibroblastic tumor" reportable for Brain and CNS sites? See Discussion. | Histology code 8825/1 (Inflammatory Myofibroblastic Tumor) is not listed in the ICD-0-3 Primary Brain and CNS Site/Histology listing for reportable Brain/CNS tumors. | If the inflammatory myofibroblastic tumor is primary in one of the sites specified below and diagnosed 1/1/2004 or later, it is reportable.
Reportable brain and CNS tumors are any benign and borderline primary intracranial and CNS tumors with a behavior code of /0 or /1 in ICD-O-3 diagnosed 1/1/2004 and later, of the following sites:

20091092 | MP/H Rules/Histology--Lung: How should Diagnosis Date, Diagnostic Confirmation and Histology be coded for the LEFT lung mass in the following case? PET shows a 3 cm mass in the left lung and a 2.9 cm mass in the right lung. No reportable terminology in PET. The right mass is biopsied and shows adenocarcinoma. The left mass is not biopsied. Based on rule M6, this should be reported as two primaries. No additional information in medical record. Patient expired. |
For cases diagnosed 2007 or later: For date of diagnosis, use the date of the PET scan for both primaries. For the left tumor, assign diagnostic confirmation code 8 [Clinical diagnosis only] and assign histology code 8000/3 [malignant neoplasm]. The left lung mass is reported as a separate primary because there is one tumor in each lung. According to Rule M6, when there is one tumor in the left lung and one tumor in the right lung, each tumor is a separate primary. Tumor and mass are equivalent terms for purposes of the multiple primary rules. |

20091034 | CS Extension--Ovary: How are the following terms coded when they are described in the medical record without any other qualifying information? Seeding, talcum powder appearance, salting, miliary, and studding. | This answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2.Seeding, talcum powder appearance, salting and studding are synonymous with implants. When the size of implants is not stated, but operative report and scans state "seeding," "talcum powder appearance," "salting," and "studding" the CS extension code choice will depend on the location of the seeding, talcum powder appearance, salting, or studding.
The word "miliary" is not documented as a synonym for implants. The term miliary does not affect the CS extension code choice according to the current CS instructions. |

20091040 | MP/H Rules/Histology--Breast: How is histology coded for an "infiltrating papillary carcinoma" of the breast when there is no mention of ductal or adenocarcinoma in the pathology report? | For cases diagnosed 2007 or later, assign histology code 8503 [Papillary adenocarcinoma]. Rule H14 applies. ICD-O-3 code 8050 does not apply in this case. Refer to the numeric listing in ICD-O-3. 8050 is a squamous cell neoplasm. Papillary carcinoma of the breast is NOT a squamous cell neoplasm. It is a neoplasm of the breast parenchyma - ducts, lobules or connective tissue. 8503 is the correct code in this case. |

20091015 | MP/H Rules/Histology--Gallbladder: What histology is coded for a tumor described as "90% high grade neuroendocrine ca, large cell type; and 10% low grade adenocarcinoma, conventional type"? | For cases diagnosed 2007 or later: MP/H Rule H17 for Other Sites applies. Code the histology 8140 [adenocarcinoma]. The ICD-O-3 code for large cell neuroendocrine carcinoma is 8013 and the code for adenocarcinoma is 8140. |

20091018 | MP/H Rules/Multiple Primaries/CS Extension: How many primaries are to be accessioned when tumors are present bilaterally in the pleura and fallopian tubes? See Discussion. | For both pleura and fallopian tube, the MP/H rules indicate that bilateral involvement of these sites should be coded as multiple primaries. However, both of these sites have CS extension codes that classify the contralateral disease as regional extension. Is a case described as a left sided pleural mesothelioma that has right sided pleural disease coded as one or two primaries? How is CS coded? |
For cases diagnosed 2007 or later: For a pleural or fallopian tube primary, if there is tumor(s) on the left and separate tumor(s) on the right and neither is stated to be metastatic from the other, abstract as multiple primaries according to rule M8 for other sites. If both sides are involved, but there is only one tumor, rule M2 for other sites applies and this is a single primary. Code each primary separately in CS. |

20091073 | Grade: Can FIGO grade be used to code Grade/Differentiation? See Discussion. | SINQ 20020059 says not to use FIGO grade to code differentiation. It also says SEER is evaluating whether the ICD-O-3 sixth digit differentiation codes accurately represent the FIGO grade. For the time being, do not code FIGO grade. What is the result of the evaluation? Any new information regarding FIGO grade? | This answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2.Do not code FIGO grade in the grade field. The conversion from a three-grade system to a four-grade system does not work for FIGO grade three. Since FIGO G3 includes both Poorly differentiated and undifferentiated, it cannot be converted. FIGO grade may be captured in a CS site specific factor in the future. |

20091023 | Sugery of Primary Site--Breast: When a patient is simultaneously diagnosed with bilateral breast cancer and bilateral mastectomies are done, do you code the total mastectomies to 40 or 41 or 42? | Abstract cancer of the left breast and cancer of the right breast as separate primaries. Code the surgery for each primary independent of the other primary. For the first primary, assign code 41 [Total (simple) mastectomy, NOS WITHOUT removal of uninvolved contralateral breast]. For the second primary, assign the code for the procedure performed on that site. |

20091110 | MP/H Rules--Bladder: Should an invasive urothelial carcinoma of the bladder diagnosed in 2004 followed by an in situ urothelial carcinoma of the ureter diagnosed in 2008 be reported as multiple primaries per the three-year guideline in Rule M7 or a single primary per the subsite guideline in Rule M8? See Discussion. | Rule M7 states, "Tumors diagnosed more than three (3) years apart are multiple primaries." Should this rule be modified to say, "Bladder tumors diagnosed more than three (3) years apart are multiple primaries"? Does Rule M7 apply to only bladder tumors or does this rule apply to tumors in any of the urinary sites similarly to Rule M8 which states, "Urothelial tumors in two or more of the following sites are a single primary: Renal pelvis (C659) Ureter (C669) Bladder (C670-C679) Urethra/prostatic urethra (C680)"? | For cases diagnosed 2007 or later, Rule M7 pertains to renal pelvis, ureter, bladder and other urinary sites as defined by the topography codes listed in the header of these rules.
An invasive urothelial bladder tumor followed more than three years later by an in situ TCC of the ureter are reported separate primaries. Rule M8 applies when the tumors in these sites are diagnosed within three years of each other.

20091126 | MP/H Rules/Multiple primaries--Vagina: How many primaries should be abstracted for a patient with a complex history of multiple occurrences of vaginal intraepithelial neoplasia (VAIN III) between 2001 and 2008 and invasive squamous cell carcinoma (SCCA) of the vagina diagnosed in 2006 and again in 2008? See Discussion. | Patient had VAIN III in March of 2001. She had a partial vaginectomy and then continues to have laser surgery in 2002, 2003, 2005 and 2006 for recurrences. In 12/2006 she is diagnosed with SCCA of the vagina with microinvasion (new primary). Then in 2/2008 she has VAIN III again -- new primary according to rule M10 (more than 1 year later). An invasive SCCA of the vagina is again diagnosed in 9/2008. Is this another new primary per rule M15 (invasive after in situ)? Every instance in 2008 is called a recurrence, but we disregard that statement. | There are two primaries according to the information provided.
1. VAIN III March 2001. 2. SCCA of vagina Dec. 2006 (invasive tumor following an in situ
For cases diagnosed 2007 or later, the MP/H rules apply to new tumors, which means that there has been a disease-free interval at some point. In this case, the patient has never been declared disease-free (NED) using the information provided in the question. The consistent recurrence of VAIN is typical of this disease. |
