20021210 | Date of Diagnosis/Histology (Pre-2007)--Breast: When there is a delay between the clinical diagnosis of a malignancy and the surgical resection of the primary site, can the resection be used to code the date of diagnosis, extension, size of the primary tumor, and histology? See discussion. | For example, mammogram March 28th states "certainly represents malignancy." Nothing else done until November 1st when pt presents w/skin retraction on PE and bone mets. A mastectomy November 6th shows "ductal ca w/dermal lymphatic invasion and tumor measuring 3.5 cm."
How is the date of diagnosis, extension, tumor size & histology coded for this case? |
For tumors diagnosed prior to 2007:
Code the Date of Diagnosis to March. Code the Histology field to 8500/3 [Infiltrating duct carcinoma]. Histology can be upgraded from a clinical histology to a pathological histology anytime.
For cases diagnosed 1998-2003, in coding extension, you need to assess whether there has been progression of disease or not. If progression of disease is verified, do not code extension using the surgical information from November. Code the extension and tumor size based on the mammogram and physical examination at the time of the mammogram, if available.
If no progression of disease is verified, use surgical information to code extension and tumor size.
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. |

20021060 | EOD-Size of Primary Tumor: The EOD Manual instructs us not to code the size of a cyst. Can we code the size of tumor lesions described as being multicystic, multiloculated, or as a complex mass with cystic areas? See discussion. | Example 1: Large multicystic ovarian mass lesion measuring 10 cm. Sections through the specimen show a multicystic and solid mass with abundant fluid exuding from the cut surfaces (Size of the solid portions is not stated).
Example 2: A brain MRI: 9-cm. complex mass with cystic areas. |
For cases diagnosed 1998-2003:
Yes, if the cystic mass is pathologically confirmed to be malignant, code the EOD-Size of Primary Tumor field based on the size of the mass in the absence of a more precise tumor size description. For the examples in the discussion section, code the EOD-Size of Primary Tumor field to: 1) 100 [10 cm]. 2) 090 [9 cm].
As a point of interest, the size of tumor for ovarian and brain primaries is not used in either analysis or as a prognostic indicator for survival. Therefore, spending time separating the cystic and solid portions of the tumor is unnecessary. |

20021006 | EOD-Extension--Hematopoietic, NOS: If a solitary plasmacytoma originates in the right tonsil and extends to the left tonsil, vallecula and hypopharynx, is extension still coded to 10 [localized disease, solitary plasmacytoma only]? | For cases diagnosed 1998-2003:
Code the EOD-Extension field to 10 [localized disease, solitary plasmacytoma only] for all cases of solitary plasmacytoma. |

20021165 | EOD-Size of Primary Tumor--All Sites: Is there a hierarchy for using information from clinical tests (scans, radiography) to determine clinical tumor size? When the size on a radiographic report prior to pathologic diagnosis is smaller than the size of the tumor on the radiographic report that is post pathologic diagnosis, which tumor size should be used? See discussion. | Which size should be used for these examples? 1) Tumor size on a mammogram is smaller than the tumor size on an ultrasound. 2) CT of the lung reveals a 2.5 cm RUL malignancy in June. A biopsy in July confirms a malignancy. A CT is done in August prior to initiating RT which reveals a 3.1 cm RUL nodule. |
For cases diagnosed 1998-2003:
Generally, code the EOD-Size of Primary Tumor field to the largest size identified in any scan. Use the largest tumor size for most cases. There is no hierarchy for multiple imaging studies, with the exception of the two situations represented in the question examples. 1). Code the size stated on the mammogram, even if that size is smaller than the one specified on the ultrasound. Generally the mammogram size is more accurate for breast cases than ultrasound. 2). Code the EOD-Size of Primary Tumor field to 2.5 cm. In this example, the second scan was the same type as the first. Usually there is not that much of a difference in size between the same tests, unless the tumor has an aggressive histology. The example does not mention the histology. With certain histologies, such as small cell of the lung, a rapid growth in a short amount of time is the normal process. The fact that the size increased that much in a short period of time, using the same type of scan, is an indication of a rapidly growing tumor. It would be better to use the size on the initial scan to code the EOD-Size of Primary Tumor. |

20020049 | EOD-Extension--Breast: Should clinically mentioned "thickening" of the breast be ignored if the pathology report does not mention thickening or skin involvement? See discussion. | For cases diagnosed 1998-2003: Can clinical "thickening" of the breast be coded to 20-28 extension code when there is no mention of the thickening or skin involvement in the pathology report? How do we code cases when pathology reports don't support the clinical finding of skin involvement. | For cases diagnosed 1998-2003: Do not use code 20-28 when there is no preoperative treatment and the pathology report does not confirm skin invasion. The clinical diagnosis of skin involvement was not supported by the pathology report. | 2002 |

20021180 | Surgery of Primary Site/Other Cancer-Directed Therapy--Head & Neck (Nasal cavity): Should a small fragment of bone removed during a maxillectomy following a turbinectomy for a nasal turbinate primary be "partial or total removal with other organ" for coding this field? See discussion. |
Excision of a turbinate mass and partial turbinectomy revealed melanoma of the rt nasal turbinate. A subsequent rt medial maxillectomy was performed and a small fragment of bone was included in the resection and identified in the pathology report. Would the removed bone be "connective or supportive tissue" only for a Surgery of Primary Site code of 40 or is it another organ for a code of 60? |
The piece of bone was likely removed to access the maxillary sinus and would not be a separate organ. Use the "All Other Sites" surgery coding schemes to code this primary. For cases diagnosed 1/1/2003 and after: Code the Surgery of Primary Site field to 40 [Total surgical removal of primary site]. Code the Surgical Procedure of Other Site field to 2 [Non-primary surgical procedure to other regional sites]. The maxillectomy was not performed in continuity to the turbinectomy and should be coded in this field rather than the Surgery of Primary Site field. |

20021162 | Chemotherapy: Should radiosensitizing chemotherapy agents (i.e., drugs typically coded as treatment for cancer) be coded as treatment when they are given in combination with radiation therapy with the intention of enhancing that treatment? See discussion. |
Per our consultant, these drugs are given at a lower dose than that typically given to treat cancer patients. |
Do not code radiosensitizers and radioprotectants as cancer-directed therapy. Drugs typically classified as chemotherapy agents would be "ancillary drugs" for the purpose of coding cancer-directed therapy because the drugs are given at a much lower dosage than that typically given to treat cancer patients. Per Book 8, ancillary drugs are not to be coded as cancer-directed therapy. Radiosensitizers and radioprotectants do not work directly on the cancer and are not coded under any of the systemic therapy fields. |

20021175 | Histology (Pre-2007): What code is used to represent the histology if the final diagnosis between an electron microscopy report and the immunocytochemistry (ICC) differs and both histologies are specific (e.g., one report states papillary carcinoma and the other states squamous cell carcinoma)? | For tumors diagnosed prior to 2007:
There is no established hierarchy between electron microscopy and ICC findings. Contact the pathologists involved in these types of cases to determine the final histologic diagnosis.
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. |

20020035 | First Course Treatment--Lymphoma: How should an antibiotic regimen such as bismuth or omeprazole, amoxicillin, and metronidazole be coded for a MALT lymphoma of the stomach associated with Helicobacter pylori infection? See discussion. |
If we do not count the antibiotic regimen as cancer-directed treatment but this is the only treatment given and the lymphoma disappears, is it problematic to have a cancer status of "no disease" recorded in a patient that supposedly was not "treated"? |
Do not code antibiotic regimens as Cancer-Directed Therapy. These drugs are intended to treat the bacteria and not the cancer. This type of treatment is ancillary even if it is the only type of treatment given. You may designate a user-defined field to capture this information if desired. The coding combination of a cancer status of "no disease" and all treatment fields coded to "no treatment" is allowable. |

20021069 | Histology (Pre-2007)--Breast: What code is used to represent the histology "infiltrating lobular carcinoma, solid and classical subtypes"? | For tumors diagnosed prior to 2007:
Code the Histology field to 8520 [Lobular carcinoma].
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. |
