EOD-Extension/EOD-Lymph Nodes--Cervix: How do you code these fields when the cancer extended to the pelvic wall and there are periaortic LN metastases?
For cases diagnosed 1998-2003:
Assign extension code 65 for contiguous (direct) extension of tumor from the cervix to the pelvic wall. Assign extension code 85 only if the pelvic wall is involved with discontinuous extension from the cervix; i.e., the cervical tumor spread indirectly (through lymph or vascular channels) to the pelvic wall. Code the pelvic wall involvement in the Extension field and the periaortic lymph node involvement in the Lymph Node field. When the computer does the algorithm, it will look at the periaortic lymph nodes and report the summary stage as distant and the TNM stage group as IV because periarotic nodes are M1. Do not code the periaortic lymph nodes in both fields. This is stage IV, distant disease, due to the periaortic lymph node involvement (EOD lymph nodes code 6).
Surgical Fields--Head & Neck: How does one code the removal of benign submandibular and sublingual glands performed during a neck dissection for a head and neck cancer? See discussion.
Should the removal be coded as incidental in the surgical Procedure if the Other Site field? Does it make a difference if the submandibular gland is removed en toto with lymph nodes or if the gland is submitted as a separate specimen? Does it make a difference if the glands are involved?
Removal of the lower salivary glands is part of a radical neck dissection and is not recorded in Surgery of Primary Site or Surgery of Other Site. Radical neck dissection is coded under "Scope of Regional Lymph Node Surgery."
It does not matter whether or not the gland is submitted as a separate specimen. It does not matter whether or not the gland is involved.
Multiple Primaries (Pre-2007)/Date of diagnosis--Cervix: How is this field coded when initially carcinoma in situ is diagnosed by biopsy and at a later date invasive tumor is found pathologically?
For tumors diagnosed prior to 2007:
Since carcinoma in situ of the cervix is not reportable to SEER (as of 1/1/1996), the diagnosis date is the date of the invasive 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.
Surgery of Primary Site--Skin: How should this field be coded for a re-excision or wide excision of a skin primary when the margins are NOS?
For cases diagnosed 2003 and later:
Assign surgery codes 45, 46 and 47 only when the margins are documented to be more than 1cm. Use the most appropriate code from 30-36 if re-excision or wide excision followed a biopsy. Use a code from the 20's series if the procedure is called a "biopsy."
Reason No Cancer-Directed Surgery--Hematopoietic, NOS: Is this field always coded to 1 [not performed, not part of first course] for leukemias & other hematopoietic diseases?
For cases diagnosed 2003 and later: For sites where "Surgery of the primary site" is coded 00 or 98 (hematopoietic included), Reason for No Surgery of Primary Site should be coded as 1 [Surgery of the primary site not performed because it was not part of the planned first course of treatment]. On rare occasions, there may be surgery to the primary site for a hematopoietic disease, such as an excisional biopsy of a myeloid sarcoma. Refer to the "Abstracting and Coding Guide for the Hematopoietic Diseases" for cell-type-specific treatment information.
First Course Therapy: Are radio immune labeled antibodies, such as Bexxar [Tositum--I-131] coded as immunotherapy, radiotherapy, or experimental therapy?
Agents such as Bexxar or Zevalin are radioisotopes and coded as radiation. These agents destroy cancer cells with radiation.
Primary Site/Behavior Code/EOD-Extension: How would these fields be coded for "squamous cell carcinoma in situ involving papilloma -- locally aggressive but not technically invasive" found in the sphenoid sinus, soft tissue of the skull base and brain? See Description.
The managing physician has staged this pathologically as T4 N0 M0 squamous cell carcinoma of the ethmoid sinuses. The final pathology report says " Sinus, sphenoid, resection: papillary neoplasm most consistent with inverted papilloma with squamous cell carcinoma in situ, 7 cm in greatest extent, focus of probable superficial invasion (see comment).
Soft tissue, skull base, excision: involved by papillary neoplasm with squamous cell carcinoma in situ (see comment). Brain, extradural, intercranial biopsy: involved by papilloma with squamous cell carcinoma in situ. COMMENT:
This is a predominantly exophytic neoplasm with infolding of the tumor epithelium and in situ extension into submucosal glands. There are only focal areas suspicious for invasive squamous cell carcinoma, with probable invasion (<2mm) in one section....The histologic features are most consistent with an inverted papilloma with carcinoma in situ." When asked to comfirm if the diagnosis were in situ or superficially invasive, the pathologist responded "Squamous cell carcinoma in situ involving a papilloma. Locally aggressive but not technically invasive."
Code site to C31.3 [sphenoid sinus]. Code the site based on the final pathology report diagnosis. In the case example, the site attributed to the managing physician appears to be an error.
Code behavior to 3 [malignant, primary site]. The SEER list of terms meaning involvement may be used to help determine behavior. The terms used by the pathologist are "probable" superficial invasion and "suspicious" for invasive squamous cell carcinoma with "probable" invasion. Interpret as invasive.
For cases diagnosed 1998-2003: Code extension to 70 [Brain] because this tumor involves the brain.
EOD-Extension: How is this field coded for synchronous primaries when metastatic disease is found and there is no statement to indicate which primary is the source of the metastases? See Description.
Patient was diagnosed with both esophageal and pancreatic cancer. Liver metastases were also identified. The source of the liver mets is unknown.
For cases diagnosed 1998-2003: Search the record for information about the source of the metastasis. If no such information can be found, code the metastasis to both primaries. Update the abstracts when information becomes available confirming the primary site responsible for the metastasis. Assuming the liver metastases in the example above are distant (i.e. not contiguous) code extension as 85 [Metastasis].
Behavior Code/EOD-Extension--Colon: Are extension codes 10 [Mucosa, NOS (incl. Intramucosal, NOS)] and 11 [Lamina propria] in situ, in accordance with AJCC stage for this site?
For cases diagnosed 1998-2003: EOD codes 10 and 11 are invasive. SEER, to be compatible with Summary Stage 77 and 2000, calls EOD extension codes 10 and 11 invasive because invasion of the lamina propria is invasion through the lamina propria/basement membrane and therefore invasive.
According to AJCC, the survivial rates for tumors that invade only the mucosa or lamina propria are similar to Tis tumors, so the AJCC classifies them as Tis.
Terms of involvement--Lung: Is "intense uptake" described on a PET scan an indication of involvement? See Description.
We are seeing increasing use of PET scans as diagnostic tools for cancer. PET scans use different terminology than the ambiguous terms listed in the EOD manual. Could we please have guidelines for interpreting PET scans?
Example: Patient with right lung cancer. PET scan showed intense uptake in the mediastinum and in the hilum. Can we code "intense uptake" as involvement of mediastinal and hilar lymph nodes?
Do not interpret "intense uptake" as involvement. Look for a statement of involvement or other terminology, such as "highly suspicious," "strongly suspicious for" malignancy, involvement, etc.
