CS Extension/Histology (Pre-2007)--Breast: Paget disease with underlying DCIS. How should CS Extension, SEER Summary Stage 2000, histology, and behavior be coded?
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.
For tumors diagnosed prior to 2007:
Based only on the information provided above,
1. The CS extension code is 07 [Paget disease of nipple (without underlying invasive carcinoma pathologically)].
2. The SS 2000 stage is 1 [Localized].
3. The histology code is 8543 [Paget disease and intraductal carcinoma of breast]. The behavior code is 3 [Malignant].
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--Melanoma: If the surgical margins are greater than 1 cm for length and width but less than 1 cm for depth, do we code surgery in the 30-33 range?
Yes, assign a surgery code from the 30-33 range when any margin is less than 1 cm. Since tumor thickness is an important prognostic factor for cutaneous melanoma, the deep margin is of particular importance.
Surgery of Primary Site--Breast: How is this field coded when a patient has a reduction mammoplasty (for macromastia) and within the pathology specimen there is an incidental finding of carcinoma?
Code this reduction mammoplasty to the code which best fits the amount of tissue removed. Read the operative report carefully. Code as a partial mastectomy, skin- nipple- areola-sparing mastectomy, or total (simple) mastectomy. Use text fields to record the details.
Summary Stage 2018/Extension--Prostate: Can imaging be used to code SEER Summary Stage 2018? MRI shows tumor involved the seminal vesicles and the patient did not have surgery. AJCC does not use imaging to clinically TNM stage a prostate case.
Note 5 was changed in Version 2.0.
Per Note 5 of the 2018 SEER Summary Stage Prostate chapter: Imaging is not used to determine the clinical extension. If a physician incorporates imaging findings into their evaluation (including the clinical T category), do not use this information.
This note was changed in Version 2.0 (2021 changes) to be in line with how AJCC stages; therefore, AJCC and Summary Stage agree.
EOD-Pathologic Review of Number of Regional Lymph Nodes Positive and Examined: How are these fields coded if radiation to the primary site and/or regional lymph nodes is performed prior to surgery?
For cases diagnosed 1998-2003:
Code the EOD-Pathologic Review of Number of Regional Lymph Nodes Positive and Examined fields per the information in the pathology report(s). Radiation to the primary site would not affect the status of the lymph node involvement. Radiation to the regional lymph node region may or may not affect the pathologic status of the lymph nodes. However, for these fields code the best information available about the status of the lymph nodes which is reflected in the pathology report(s).
Radiation: Is "consolidated" radiation therapy coded as part of first course therapy when there is no documentation of "planned treatment" and the radiation is done 4 months after the initiation of treatment?
Yes, "consolidation" treatment is part of a planned treatment regimen. A treatment regimen may consist of the four following phases:
MP/H Rules--Breast: Is inflammatory breast cancer always one primary per lifetime? Or is a subsequent inflammatory breast cancer a second primary if diagnosed more than five years later?
For cases diagnosed 2007 or later, a diagnosis of inflammatory breast cancer more than five years after a previous diagnosis of inflammatory breast cancer is a separate (new) primary. See rule M5 in the Breast Multiple Primary Rules.
CS Extension--Lung: How is this field coded for a tumor in the right middle lobe with extension to the bronchus intermedius?
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.
Assign CS extension code 20
[Extension from other parts of lung to main stem bronchus, NOS
(EXCLUDES superficial tumor as described in code 11)
Tumor involving main stem bronchus greater than or equal to 2.0 cm from carina (primary in lung or main stem bronchus)].
A right middle lobe tumor that extends to the bronchus intermedius is one that is extending to the main stem bronchus from another part of the lung. The bronchus intermedius is the lower part of the main stem bronchus on the right. It is more than 2.0 cm away from the carina.
EOD-Extension/EOD-Lymph Nodes: Can the AJCC TNM/Stage be used to help code these fields when there is limited text information in the medical record that describes the tumor involvement?
For cases diagnosed 1998-2003:
Yes, this staging information can be used to help code the SEER EOD fields but only if a physician does the TNM/Stage at the time of diagnosis and there is limited text information that describes tumor involvement.
Surgery of Primary Site--Skin: For skin primaries diagnosed 1998-2002, what is the difference between code 40 [Wide excision or re-excision of lesion or minor (local) amputation, NOS] and 50 [Radical excision of a lesion, NOS]?
Codes 40 and 50 are not in the scheme for 2003 forward. See history for coding cases diagnosed 1998-2002.
