20170030 | Surgery Primary Site--Melanoma: How should Surgery of Primary Site be coded for a melanoma diagnosed on punch or shave biopsy followed by a wide excision that shows no residual disease and the gross wide excision specimen size showing no residual is greater than 1 cm in all dimensions (length, width and depth)? See Discussion. |
Discussion: Example: Shave biopsy with superficial spreading melanoma, Breslow 0.25 mm, Clark level II. Excision with no residual melanoma and gross description of specimen size is 4.0 x 1.6 cm skin ellipse excised to a depth of 1.8 cm. We have differing opinions in our registry. Opinion 1: We can assume margins are greater than 1 cm based on the excision specimen size when there is no residual tumor on excision and all dimensions of the excision specimen are more than 1 cm. Surgery would be coded in 40s range. Opinion 2: We should assume the melanoma defect was in the middle of the excision specimen, so for a skin ellipse that is 4.0 x 1.6 cm, there would be a 2 cm and 0.8 cm margin (respectively) from the middle of the specimen, thus margins are not > 1 cm. Surgery would be coded in 30s range. |
Assign code 30: Biopsy of primary tumor followed by a gross excision of the lesion. The margins are unknown. The registrar should not try to determine the margins when they are not specified. See the SEER Note at the top of page 2 in the Skin Surgery Codes section of Appendix C of the SEER manual "If it is stated to be a wide excision or reexcision, but the margins are unknown, code to 30." https://seer.cancer.gov/manuals/2016/AppendixC/Surgery_Codes_Skin_2016.pdf |

20150011 | Surgery Primary Site--Breast: Please clarify how to code both simple mastectomy with tissue expander and AlloDerm reconstruction, and simple mastectomy with tissue expander (NOS). See discussion. |
There are multiple SEER Notes in the Breast Surgery Codes of Appendix C instructing us to code tissue expanders as reconstruction but none address the type of reconstruction to be coded.
1. Is a tissue expander always equivalent to Implant reconstruction? 2. Is AlloDerm always equivalent to Tissue reconstruction? 3. Is the combination of AlloDerm and tissue expander always equivalent to Combined (tissue and implant) reconstruction? |
Do not code AlloDerm as either a tissue or implant reconstruction, it is a graft material that usually accompanies implant reconstruction. Placement of a tissue expander is an indication of planned reconstruction. Additional information is needed to determine whether the reconstruction involves tissue or implant.
1. A tissue expander is not always equivalent to Implant reconstruction 2. AlloDerm is not equivalent to tissue reconstruction 3. The combination of AlloDerm and tissue expander is not equivalent to combined (tissue and implant) reconstruction |

20000431 | Surgery Fields--Multiple sites: What code is used to represent these fields for the following surgical procedures?
1. Tongue, NOS - Hemiglossectomy with lymph node dissection 2. Choroid - Eye enucleation 3. Vulva, NOS - Vulvectomy with bilateral lymph node dissection 4. Gallbladder - Cholecystectomy 5. Lung - Laminectomy with partial removal of tumor |
For cases diagnosed 1/1/03 and later: 1. Code Surgery of Primary Site to 30 and Scope of Regional Lymph Node Surgery to 3. 2. Code Surgery of Primary Site to 41. 3. Code Surgery of Primary Site to 40 and Scope of Regional Lymph Node Surgery to 3. 4. Code Surgery of Primary Site to 40. 5. Code Surgical Procedure of Other Site to 4. |

20180082 | Summary Stage Manual 2018 "Lymphoma: SEER Summary Stage 2000 states: For lymphomas, any mention of lymph nodes is indicative of involvement and is used to determine the number and location of lymph node chains involved (see lymphoma scheme). This statement is not in SEER Summary Stage 2018. Does that mean we follow rules #4-7, pages 14-15, under Code 3: Regional Lymph Nodes only, for every site, including lymphoma? |
The following statement "Any mention of the terms including fixed, matted, mass in the hilum, mediastinum, retroperitoneum, and/or mesentery, palpable, enlarged, shotty, lymphadenopathy are all regarded as involvement for lymphomas when determining appropriate code," is included in EOD Primary Tumor and is applicable to Summary Stage 2018. The statement will be added as note 4 to the Lymphoma Summary Stage chapter. This will be included in the 2019 update (estimated release January 2019). |

20190030 | 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. |

20200067 | Summary Stage 2018/Extension--Colon: What is the Summary Stage for adenocarcinoma of cecum where the tumor extends into the proximal portion of attached vermiform appendix? See Discussion. |
2020 Diagnosis: Patient had a right hemicolectomy showing adenocarcinoma of cecum, tumor extends into proximal portion of attached vermiform appendix. Tumor invades through muscularis propria into pericolorectal tissues (NOS). Regional lymph nodes: 06/39. Primary Tumor EOD: Where does the appendix involvement come into coding or will this be based on the pericolorectal tissue (NOS) invasion? What is my Summary Stage? I know it is at least 3 due to regional ln involvement, but the appendix involvement is making me question 3 vs 4. |
Assign code 4, Regional by BOTH direct extension AND regional lymph node(s) involved. In this case, the Regional component for Summary Stage 2018 is based on Note 6, under Colon and Rectum where Regional is defined as: -Mesentery -Peritonealized pericolic/perirectal tissues invaded [Ascending Colon/Descending Colon/Hepatic Flexure/Splenic Flexure/Upper third of rectum: anterior and lateral surfaces; Cecum; Sigmoid Colon; Transverse Colon; Rectosigmoid; Rectum: middle third anterior surface] -Pericolic/Perirectal fat |

20200068 | Summary Stage 2018/Extension--Colon: Are colon primaries coded as local or regional (direct extension) on Summary Stage based on invasion into the pericolorectal tissues? For example, is a case with an ascending colon tumor that extends into the pericolorectal tissues, pT3, local or regional by direct extension? |
Code as Localized using the SEER Summary Stage Manual, Colon and Rectum, Note 6. Localized is for subsites that are not peritonealized, including the posterior side of the ascending colon, or when the pathologist does not further describe the "pericolic/perirectal tissues" as either "non-peritonealized pericolic/perirectal tissues" vs "peritonealized pericolic/perirectal tissues" fat and the gross description does not describe the tumor relation to the serosa/peritoneal surface, and it cannot be determined whether the tumor arises in a peritonealized portion of the colon. Refer to the coding instructions in both EOD and Summary Stage for a list of sites that are nonperitonealized or peritonealized. . |

20190077 | Summary Stage 2018/EOD 2018: How should SEER Summary Stage 2018 be coded for a 2018 thymus primary which has mediastinal fat invasion without mediastinal pleural involvement? See Discussion. |
The Extent of Disease (EOD) manual states that "Confined to thymus WITH mediastinal or pleural involvement" should be coded as regional by direct extension. I have EOD primary tumor coded as 200 and based on SEER*RSA, this is localized. |
Code 200 derives Regional Extension (RE) for Summary Stage; however, based on the information you provided, thymus primary with mediastinal fat invasion without mediastinal pleural involvement, EOD Primary Tumor would be coded to 100: Confined to thymus (encapsulated tumor), which includes extension into the mediastinal fat; No mediastinal or pleura involvement. This derives "Localized" for Summary Stage. Per AJCC T1, extension into the mediastinal fat is separate from involvement of the mediastinal pleura. For Summary Stage 2018, this would be code 1, Localized only (localized, NOS): Confined to thymus, NOS; No mediastinal or pleura involvement or UNKNOWN if involved. We will note that "extension into the mediastinal fat" is included in code 100 for the next release (September 2020). |

20200049 | Summary Stage 2018/EOD 2018--Lymphoma Orbital Adnexa: What is the correct Summary Stage 2018 (SS2018) for the site/histology Orbit, NOS (C696), 9699/3? In SEER*RSA, Extent of Disease (EOD) Primary Tumor references code 7 (Distant), whereas SS2018 assigns code 2 (Regional)? See Discussion. |
We received an edit error in SEER*DMS on the following site/histology (Orbit, NOS (C696)/9699/3) that involved an incorrect staging code being assigned to SS2018. The staging language is identical in AJCC, EOD and SS2018. SEER*RSA notes that SS2018 should be coded distant, but in the SS2018 manual, this language is noted Regional. Staging language is: Orbital adnexal lymphoma AND extraorbital lymphoma extending beyond the orbit to adjacent structures--Bone, Brain, Maxillofacial sinuses |
To clear this edit of the derived Summary Stage (based on EOD) and the manually assigned Summary Stage (based on Summary Stage 2018), assign the manually assigned Summary Stage to 7. For this particular case, EOD Primary Tumor 700 (which is correct based on the information received) derives Distant; however, for Summary Stage 2018, this description is under Code 2 for Regional by direct extension. This is an error. For 2022, Summary Stage for Lymphoma Ocular Adnexa description under Code 2 (Regional by direct extension) will be moved to Distant. No changes will be done to EOD. |

20210047 | Summary Stage 2018/EOD 2018--Colon: Does the 2018 SEER Summary Staging Manual, Digestive System Sites, Distinguishing In Situ and Localized Tumors for the Digestive System, #1. b., Exception, include in situ plus intramucosal carcinoma (involvement of the lamina propria and may involve but not penetrate through the muscularis mucosa) (penetration through the muscularis mucosa is behavior code 3.)? This seems to be in conflict with Extent of Disease (EOD) 2018. See Discussion. |
We are preparing to send our hospitals a reminder that the behavior changes from 2 to 3 at the bottom of the basement membrane, and the T category changes from Tis to T1 at the bottom of the mucosa for colon and rectum carcinomas. We are confused by the wording of the Exception. Distinguishing In Situ and Localized Tumors for the Digestive System 1.b. If the tumor has penetrated the basement membrane to invade the lamina propria, in which case it is localized and assigned Summary Stage 1 (localized) and for invasion of the lamina propria Exception: Code 0 (behavior code 2) includes cancer cells confined within the glandular basement membrane (intraepithelial); includes in situ plus intramucosal carcinoma (involvement of the lamina propria and may involve but not penetrate through the muscularis mucosa) (penetration through the muscularis mucosa is behavior code 3.) The text following (intraepithelial) is unclear. The question is: Does the text include in situ plus intramucosal carcinoma (involvement of the lamina propria and may involve but not penetrate through the muscularis mucosa) (penetration through the muscularis mucosa is behavior code 3.) mean the following: Code 0 (behavior code 2) includes in situ plus intramucosal carcinoma. In situ plus intramucosal carcinoma is involvement of the lamina propria, which may involve (but not penetrate through) the muscularis mucosae. Penetration through the muscularis mucosa is behavior 3. If that is what the text above means, then it seems that the 2018 SEER Summary Stage Manual is saying colorectal tumors reported as: adenocarcinoma in situ, at least intramucosal adenocarcinoma in situ, high grade dysplasia/intramucosal adenocarcinoma in situ, focally intramucosal at the margin are to be coded behavior 2 and SEER Summary stage In situ (0) like the intraepithelial carcinoma tumors. However, it conflicts with the EOD Data for Colon and Rectum, Note 2, and SINQ 20210006. The text for both EOD Data for Colon and Rectum and SINQ 20210006 is clear. According to them, the above bulleted adenocarcarcinoma examples are coded SEER Summary Stage localized (1) and behavior 3. SINQ 20210006 states that: For purposes of Summary Stage, intramucosal carcinoma is a localized lesion So, intramucosal carcinoma is coded SEER Summary Stage 1 (localized) and (behavior code 3). According to the text for EOD Primary Tumor, Colon and Rectum, Note 2 below, intramucosal, NOS involvement is invasive. Note 2: Code 050 (behavior code 3) includes the following: Intramucosal, NOS Lamina propria Mucosa, NOS Confined to, but not through the muscularis mucosa Thank you for your help clarifying the 2018 SEER Summary Manual Exception text above. |
For purposes of Summary Stage, intramucosal, NOS is a localized lesion. Intramucosal carcinoma is coded SEER Summary Stage 1 (localized) and (behavior code 3). The involvement of the following are assigned localized in Summary Stage and assigned a behavior code of 3. Intramucosal, NOS Lamina propria Mucosa, NOS Confined to, but not through the muscularis mucosa The Exception you cite may need to be reworded. We will review for the next version of the Summary Stage manual. |
