20031131 | Multiple Primaries (Pre-2007): Would osteosarcoma of the right arm diagnosed four years after malignant fibrous histiocytoma, also in the right arm, be a second primary when the physician states, "the patient's disease progressed to sarcoma after radiation was administered?" |
For tumors diagnosed prior to 2007: The osteosarcoma is a second primary. The first three digits of the histology codes are different: 8830 [Malignant fibrous histiocytoma] and 918_ or 919_ [Osteosarcoma]. In addition, the diagnoses are four years apart. According to SEER rules, these are separate primaries. For tumors diagnosed 2007 or later, refer to the MP/H rules. If there are still questions about how this type of tumor should be coded, submit a new question to SINQ and include the difficulties you are encountering in applying the MP/H rules. |

20031100 | Date of diagnosis: Can a positive VMA:HVA test be used as a date of diagnosis for neuroblastoma? See Description. |
Rubin's Clinical Oncology states: Both the catecholamines and their metabolites are used as markers for neuroblastoma, with vanillylmandelic acid (VMA) and homovanillic acid (HVA) being the most commonly used. While their absolute values are not of prognostic significance, a higher VMA:HVA ratio suggests a better prognosis for patients with disseminated disease. |
Updated answer July 2024 No. Do not code the neuroblastoma diagnosis date from only the date of an elevated urine catecholamine test (VMA or HVA). Neuroblastoma diagnosis should be made on the basis of tissue biopsy or bone marrow aspiration along with elevated urinary catecholamines. Elevated urinary catecholamines alone are not diagnostic of neuroblastoma. |

20031153 | Laterality/Multiple Primaries (Pre-2007)--Ovary: Are ovarian primaries with bilateral involvement always coded to laterality 4 (bilateral)? See Description. | Example: "Right ovary with mass replacing majority of ovarian tissue consistent with serous adenoca. Lt ovary with foci of adenoca." No specific statement of primary. Can we assume that the malignancy originated in the right ovary since it is more extensively involved or should laterality be coded 4 because both ovaries have tumor? | For tumors diagnosed prior to 2007:
If one ovary is listed as the primary site, code laterality to that ovary. The example above is one of those times when you would code to the single ovary. The issue of one or both ovaries being involved is handled in staging.
Abstract the example above as a single primary with code 1 [Right] for laterality.
For tumors diagnosed 2007 or later, refer to the MP/H rules. If there are still questions about how this type of tumor should be coded, submit a new question to SINQ and include the difficulties you are encountering in applying the MP/H rules. |

20031075 | EOD-Extension--Colon: How should this field be coded for "adenocarcinoma penetrating through bowel wall into adjacent adipose tissue? | For cases diagnosed 1998-2003: The difference between EOD-extension codes 40 and 45 is the level of the fat involved. Code 40 is subserosal fat immediately adjacent to the muscular wall of the colon inside the serosa/visceral peritoneum. Code 45 is pericolic fat in areas where there is a serosal surface or in the retroperitoneal areas of the ascending and descending colon where there is no serosa. Code 42 was added for use when it is not possible to determine whether subserosal fat or pericolic fat is involved. Code 42 should be used only when there is a reference to 'fat' (NOS) The answer for the case example above depends on the location of the primary and whether the fat referred to is within or outside the entire thickness of the colon wall. If no additional information is available, use code 42 [Fat, NOS]. | 2003 | |

20031203 | Surgery of Primary Site--Skin: Should this field be coded to 45 [wide excision or reexcision of lesion or minor (local) amputation with margins more than 1 cm, NOS], 46 [with margins between 1 and 2 cm], or 47 [with margins greater than 2 cm] for a skin primary diagnosed in 2003 when margins are stated exactly as 2 cm? | Use code 46 [Wide excision...with margins more than 1 cm and less than 2 cm] when margins are exactly 2 cm. | 2003 | |

20031171 | Reportability: Is pseudomyxoma peritonei always reportable? See Description. | In the ICD-O-3, pseudomyxoma peritonei has a behavior code of 6, indicating that it is malignant. Does this imply that pseudomyxoma peritonei is always a reportable malignancy? In the past, our pathologist consultant told us that pseudomyxoma peritonei is only a reportable malignancy if the underlying tumor is malignant. A benign cystadenoma of the appendix, for example, can rupture causing pseudomyxoma perionei. Does SEER agree with our pathologist consultant? Example: Patient was found to have psuedomyxoma peritonei. Right hemicolectomy was done. Path reported an appendix with mucinous cystic tumor of undetermined malignant potential. A definite diagnosis of cancer can not be rendered. |
Reportability is determined from the behavior of the primary tumor and the behavior of implants. If either are malignant, the case is reportable. The case example does not seem to be reportable, based on the available information. Cancer diagnosis has not been made according to the pathology report. |

20031063 | Date of Diagnosis: When the clinical information on a scan indicates a history of cancer, how do you code the month and/or year of diagnosis given these terms: "early in year," "late in year," "2-3 months ago," "7 months ago," "new diagnosis." See Description. | Case 1. Diagnosed with CLL in late 1996. Assumptions: Code the term "late" in the year to December. Date of diagnosis would be coded to December 1996.
Case 2. Diagnosed with CLL in early 1997. Assumptions: Code the term "early" in the year to January. Date of diagnosis would be coded to January 1997.
Case 3. Admitted July 2000. Per H & P, patient was diagnosed with prostate cancer 2-3 years ago. Assumptions: Select the higher number in the range (in this case 3 years) and subtract 3 years from date of admit to calculate year of diagnosis. Code diagnosis month to the month patient was admitted. Diagnosis date would be coded July 1997.
Case 4. Admitted in October 2001. H&P states that colon cancer was diagnosed 7 months ago. Assumptions: Subtract 7 months from date of admit. Code date of diagnosis to March 2001.
Case 5. Admitted in December 2001. Per H&P, patient has CLL, presumably a new diagnosis. Assumptions: Assume the H&P statement of "new" to be equivalent to "recent" and code date of diagnosis to date patient was admitted. In this case, date of diagnosis would be coded to December 2001.
Case 6. Admitted for radical prostatectomy for prostate cancer in March 2001. H&P states that his PSA was 5 in November 2000 and in January 2001, PSA was 5.3. Biopsies showed adenocarcinoma. Assumptions: Assume the biopsy was done the same month as the January 2001 increased PSA. Date of diagnosis would be coded to January 2001.
Case 7. Outpatient bone scan done December 2001. Clinical history on the scan stated patient has history of prostate cancer. The physician was queried about date of diagnosis. Per the physician response, patient was diagnosed in 2001. Assumptions: Assume the bone scan was part of the initial work-up for prostate cancer and estimate the date of diagnosis to December 2001. |
SEER agrees that these are reasonable assumptions based on the information provided.
Estimate the month and year of diagnosis using the available information. If the information is not sufficient to make an estimation on the month, code the month of diagnosis as "99." Avoid coding "unknown" for the year of diagnosis. |

20031080 | Behavior Code/EOD-Extension--Bladder: How are these fields coded for a bladder tumor in which the pathologist states, "there is no definite invasion identified" but the urologist states the case as T1? See Description. | Patient presents with four bladder tumors, described as "each measuring close to 2 cm." A specimen was taken of only one of the tumors. The tops of the tumors were fulgurated, then vaporized methodically. No obvious tumor or residual was noted on re-inspection. Pathology revealed papillary urothelial carcinoma, high grade, with no definite invasion identified. Small segments of muscularis propria were present. A comment read..."it is difficult to determine if lamina propria invasion is present due to marked necrosis and tissue fragmentation." Urologist staged this as AJCC cT2a, but based on the pathology findings changed it to cT1. The urologist insists this is invasive. |
For cases diagnosed 1998-2003: Because of the damage to the specimen from cautery and the insistence of the urologist that the tumor was invasive, code extension for this case to 15 based on the physician's TNM category of T1.
A T1 is invasive--code the behavior /3. The urologist is confident it is invasive, and will likely treat the patient accordingly. |

20031032 | Diagnostic Confirmation--Hematopoietic, NOS: How should diagnostic confirmation of Hematopoietic diseases be coded in the absence of positive bone marrow? See Description. | Case 1. Patient admitted 9-12-02 with diagnosis of essential thrombocythemia. Per the H&P, patient obviously has had this since January 2001. Per the clinical history: patient with elevated platelets. Path diagnosis of bone marrow biopsy done 9-20-02 showed mildly increased megakaryocytes. 10-31-02 clinical sign-out diagnosis was: essential thrombocythemia. Case 2. Patient admitted for evaluation of erythrocytosis. Assessment: Increased hematocrit only. It is most likely that patient has polycythemia vera. I think it is reasonable to initiate phlebotomy treatment. |
Code 1, Positive histology, includes diagnostic hematologic findings and peripheral blood smears when these are the basis for diagnosis. When the clinician makes a specific diagnosis and the blood work is not diagnostic, code diagnostic confirmation as 8 [Clinical diagnosis only]. The clinician is putting together all evidence, including the blood work and using his/her professional experience to diagnose the case. Case 1. The diagnosis is not based on microscopic findings. Assign code 8 [Clinical diagnosis only]. Megakaryocytes are the immature form of thrombocytes, but mildly increased megakaryocytes are not diagnostic of essential thrombocythemia. Case 2. The diagnosis is not based on microscopic findings. Assign code 8 [Clinical diagnosis only]. |

20031146 | EOD-Size of Primary Tumor--Breast: How do we code this field when there is a difference between the size of the tumor mentioned in the gross (i.e., macroscopic description) and the comment sections of a pathology report? See Description. | Path Macro Summary states size as 1.5 cm. The path comment states "largest area of tumor seen is 1.5 cm. However, 8 of the nearly contiguous sections are involved with an estimated 2.4 cm area of involvement." | For cases diagnosed 1998-2003: Code the size of the largest area of tumor from the path macro summary. For the example provided, code the size as 015 [1.5 cm]. In this case, the additional sections of tumor described in the path comment do not seem to represent pieces of one larger tumor. The 2.4 cm estimated area of involvement was determined by adding together noncontiguous tumor sections. According to the CAP protocol for breast, Note J "When 2 or more distinct invasive tumors are present, each is separately measured...they are not combined into a single larger size." | 2003 |
