20021171 | Date Therapy Initiated: How would you estimate the date treatment began for a patient who was treated elsewhere and seen only on an outpatient basis at the current facility? See discussion. | July 19th: Retromolar trigone primary was diagnosed. August 8th note states, "Pt is not a surgical candidate due to multiple medical co-morbidities." Sept 19th note states, "Per Tumor Board, pt has been undergoing radiation for her head and neck cancer." The exact starting date for radiation is not specified.
In the SEER Program Code Manual it states that "In the absence of an exact date of treatment, the date of admission for that hospitalization during which the first cancer directed therapy was begun is an acceptable entry." |
If possible, review the radiation treatment summary and outpatient records at the treating facility. If the date treatment began is not stated, look for the completion date and number of treatments, and calculate the first date of treatment.
If the date radiation started cannot be found or calculated, code the month as 09 for the example provided. The determination was made in August NOT to treat with surgery. We know that there was treatment in September. |

20021209 | EOD-Extension/EOD-Lymph Nodes--Rectosigmoid: How do you code these fields for a scan-based clinically staged T3 N1 rectosigmoid primary in a patient who received chemotherapy and radiation prior to a resection that demonstrated invasion only into the muscularis and no positive lymph nodes? | For cases diagnosed 1998-2003:
Use the best information available, in this case, the clinical staging, to code EOD. Code the EOD-Extension field to 40 [Invasion through muscularis propria or muscularis, NOS] and the EOD Lymph Node field to 3 [Regional lymph node(s) NOS] because the case had a clinical stage of T3 N1. EOD is coded using the most extensive clinical or pathologic stage. |

20020016 | Primary Site (Pre-2007)--Prostate/Prostatic Urethra: What code is used to represent primary site for an "adenocarcinoma with spindle cell differentiation" of the prostatic urethra? | For tumors diagnosed prior to 2007:
Code the Primary Site field to C61.9 [prostate] because the histology is adenocarcinoma.
When a malignancy is identified in the prostatic urethra, look at the histology to determine the primary site. If it is a transitional cell carcinoma, code the Primary Site field to C68.0 [urethra] and if it is an adenocarcinoma, code to C61.9 [prostate].
The EOD scheme is ultimately collapsed into the TNM scheme. The TNM system differentiates between adenocarcinoma of the prostate and transitional cell carcinoma of the urethra. Only adenocarcinoma of the prostate is staged by the prostate scheme. Transitional cell carcinoma of the prostatic urethra is coded to C68.0 [urethra] and staged with that scheme.
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. |

20020053 | EOD-Extension--Meninges: How do you code extension for a malignant meningioma that invades into the adjacent brain tissue? | For cases diagnosed 1998-2003:
Code the EOD-Extension field to 60. Code 60 is defined as a brain tumor that extends into the meninges. It is also the appropriate code to use for a tumor that extends from the meninges to the brain. |

|
20021200 | Date of Diagnosis: How do you code this field when the pathologic confirmation is delayed for 2 months because the clinician decides to "watch and see what happens" to a CT identified mass thought to be either a "metastasis from a previously diagnosed malignancy or a new primary"? | Code the Date of Diagnosis field to the date of the scan. This is the earliest date that a recognized medical practitioner said the patient had cancer. The diagnosis on the CT scan was a malignancy. The only question was whether the mass on the scan was metastatic or a primary. | 2002 | |
|
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. |

20021020 | First Course Treatment: 1) When is Decadron (Dexamethasone) coded as cancer treatment? 2) When Decadron is given to a patient with multiple myeloma, is it coded as treatment only if given in combination with chemotherapy? See discussion. |
SEER Book 8 states that Decadron is an important therapeutic agent for treatment of multiple myeloma. In the Abstracting and Coding Guide for the Hematopoietic Diseases, Decadron is a hormonal treatment for multiple myeloma "when given as part of a chemotherapy regimen". |
For cases diagnosed 1/1/2003 and after: 1. Code hormone therapy to 01. Code any therapy administered to treat cancer tissue that achieves its effect on cancer tissue through a change in the hormone balance in the hormone therapy field. Decadron is coded for leukemias, lymphomas and multiple myelomas primaries. It is coded for other sites only when stated to be cancer-directed treatment. 2. Code hormone therapy to 01. Decadron should be coded as hormone therapy for multiple myeloma when given alone or as part of a first course of treatment chemotherapy regimen. |

20021003 | Multiple Primaries (Pre-2007): Whenever two hollow organs are diagnosed simultaneously with the same histology, one being invasive and the other in situ, can one assume that mucosal spread has occurred and that this situation represents one primary? In the absence of a physician statement, how do you determine mucosal spread from one organ to another? | For tumors diagnosed prior to 2007:
Yes, this type of situation represents one primary. A tumor that is breaking down can be invasive in the center with in situ cancer at the margins. Occasionally the in situ margin can move into a contiguous organ with the same type of epithelium.
Physicians may describe mucosal spread in various manners. You will see the terms "intramucosal extension," "in situ component extending to," or statements of an invasive component in one organ, with adjacent/associated in situ carcinoma in a contiguous organ with the same type of epithelium. A frequent example of this process is bladder cancer extending into the prostatic urethra via mucosal spread.
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. |

20021005 | EOD-Extension--Lymphoma: What code is used to represent this field for an extranodal lymphoma that has more than one tumor in the primary site OR has intraluminal extension from the primary site to an adjacent organ? See discussion. | 1. Small lymphocytic lymphoma with 2 tumors in the stomach. 2. Lymphoma involving the cecum and ileum. 3. Lymphoma of the fundus of stomach with extension into the esophagus. |
For cases diagnosed 1998-2003:
Using the EOD scheme for lymphoma, code the Extension field to 11 [Localized involvement of a single extralymphatic organ or site; Stage IE] for all 3 of these cases.
For the stomach lymphoma: There are 2 areas of lymphoma, but it is still confined to one site.
For the other 2 lymphomas: Intraluminal (mucosal) spread of the lymphoma never equals extension. The same phrase that was added to code 21, "Direct extension to adjacent organs or tissues", will be added to code 11 in the Collaborative Stage System. Neither "mucosal spread to a contiguous organ" or "direct extension into a nearby organ" affect staging. Both are still coded to 11 as long as there are no other sites of lymphoma involvement.
EOD code 80 is poorly written. It does not mean diffuse invovement or multiple tumors in a single organ but rather "diffuse disease in two or more organs." |

20021046 | Behavior Code/EOD-Extension--Bladder: If an in situ lesion of the urinary bladder involves the von Brunn nests, is it still in situ? See discussion. | Von Brunn nests: Compact, rounded aggregates of urothelial (transitional) cells in the lamina propria, with or without connection to the surface epithelium. Urothelial (transitional cell) carcinoma in situ...may involve von Brunn nests... Histologic Typing of Urinary Bladder Tumours, Second Edition, WHO, pp 12 & 21 |
For cases diagnosed 1998-2003:
Code the Behavior Code and the EOD-Extension field according to the pathology report.
If the pathology report states the tumor to be noninvasive or in situ, whether or not von Brunn nests are involved, code behavior as 2 [in situ] and extension as in situ.
If the tumor is described as invasive and involves the von Brunn nests, code the EOD-Extension field to 15 [invasive tumor confined to subepithelial connective tissue] because code 15 includes extension to the lamina propria and von Brunn nests are within the lamina propria. |
