CS Extension--Breast: What is the CS Extent for this 2004 breast cancer? See Discussion.
A patient had lobular carcinoma of the left breast in 2000. At that time, she had bilateral simple mastectomies and the right breast was benign. In 2004, she notices a nodule in the right chest wall, which is excised and found to be invasive ductal ca and lobular ca in situ. So is this Sequence 2, C50.9, 8522/3. And what is the CS Extent - 40 chest wall? (The physician stages this as T2N0M0)
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.Residual breast tissue is present following a mastectomy. If the nodule is in the breast tissue (tissue above the ribs), assign CS extension code 10 [Confined to breast tissue...Localized, NOS]. If the nodule is in the chest wall (tissue below the ribs), assign code 40 [Invasion of chest wall].
Histology--Lymphoma: How is "histiomonocytic lymphoma" coded?
For cases diagnosed prior to 1/1/2010:Assign code 9755 [Histiocytic sarcoma; True histiocytic lymphoma]. "Histiomonocytic" is not standard terminology, according to our expert consultant. However, 9755 is the best code to assign.
For cases diagnosed 2010 forward, refer to the Hematopoietic and Lymphoid Neoplasm Case Reportability and Coding Manual and the Hematopoietic Database (Hematopoietic DB) provided by SEER on its website to research your question. If those resources do not adequately address your issue, submit a new question to SINQ.
CS Eval--Colon: Should 1 [No surgical resection done...] or 3 [Surgical resection performed...] be used to correctly reflect this field when a surgical observation is "adherent to duodenum" but the extension per the pathology is stated to be to the "subserosal tissue"? See Discussion.
7/2/04 Op Findings 5 cm mass in mid transverse colon involving also the right colon; mass was adherent to duodenum without obvious invasion. 7/2/04 Path: Rt & Transverse Colon: 6x5 cm mass, micro: MD Adenoca with invasion of subserosal tissue; margins neg. 17/17 colic LNs negative.
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 the case described above, code extension as 46 [Adherent to other organ...no microscopic tumor found in adhesion]. Code CS TS/Ext eval as 3 [Surgical resection performed...].
Surgery was performed for this case. The fact that the adherence to the duodenum was proven not to be tumor involvement should be coded as 3 in CS TS/Ext Eval. By using eval code 3, the case will map to a pathologic T indicating that the patient had resective surgery. Eval code 1 would map to a clinical T, incorrect for this case.
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.
Reportability--Brain and CNS: Which types of neurofibromatosis are reportable to SEER? See Discussion.
Clin exam: probable neurofibromatosis, type I. On the trunk alone are >14 cafe au lait spots all at least 10mm. Both axillary regions have freckling. No palpable fibromas, spine is straight, no organomegaly. MRI of head: no abnormality.
Neurofibromatosis type I (von Recklinghausen's disease, the Elephant Man disease) is primarily tumors of the subcutaneous tissues. By itself, NF1 is not reportable. NF2 is much more likely to develop acoustic neuromas. This syndrome is reportable only when acoustic neuroma(s) is present, because the acoustic neuroma is what is reportable. This case is not reportable because none of the symptoms affect the central nervous system.
CS Lymph Nodes: Are lymphatic channels/vessels within an organ coded as regional lymph nodes?
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.Lymphatic channels/vessels carry lymph fluid throughout the organs and tissues of the body. Lymph channels/vessels within an organ are not nodes. Lymph channels/vessels outside an organ are not nodes.
Primary Site/Priorities--Breast: When there are conflicting references to subsite in different reports, which report has priority? See Discussion.
The clinical site of the palpable mass is outer quadrant. The pathologist states inflammatory breast cancer located in the central breast. Should the site be coded to C501 for central breast, C509 for inflammatory breast ca, or C508 for outer quadrant?
Code the breast subsite from the pathology report (C501, central).
The priority order for coding subsite from conflicting reports is
1. Pathology report
2. Operative report
3. Physical examination
4. Mammogram, ultrasound
The primary site of inflammatory breast carcinoma is coded to C509 when there is no palpable tumor.
Primary Site--Bladder: What subsite is used for fundus of the bladder?
As of November 2005, Code fundus of bladder to C678 [overlapping lesion of bladder]. Opinions vary regarding the definition of bladder "fundus." However, according to our pathologist consultant, fundus includes posterior, anterior and lateral walls and dome. Fundus does not include the trigone.
A correction to page C-595 of the 2004 SEER manual will be included in the next errata.
CS Eval--All Sites: If any of the CS fields (TS/Extension, LN, or Mets) are based on the TNM and there is no text documenting the basis for the evaluation, are the evaluation fields coded to 0 instead of 1?
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 code 0 [No surgical resection done...based on physical exam...or other non-invasive clinical evidence] to the corresponding eval fields when CS Extension, Lymph Nodes or Mets at Diagnosis are coded based only on the TNM and no further information is available.
CS Tumor Size/CS Extension/CS Lymph Nodes--Lung: How are these fields coded when there is no description of a primary lung tumor, lymph node biopsies are negative, but biopsy of a "level 7 mass" is positive for squamous cell carcinoma? See Discussion.
Example: Chest CT: Enlarging subcarinal mass, 3.4 cm, is most likely malignant adenopathy or perhaps primary tumor. The clinician subsequently described a patient history of mediastinal lymphadenopathy. He stated that a PET scan revealed multifocal thoracic disease consistent with stage 3B carcinoma. This was followed by mediastinoscopy with lymph node biopsies (all negative) but the biopsies of "level 7 mass and subcarinal level 7 mass" showed squamous cell carcinoma.
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.If this case is determined to be a lung primary, code the CS fields:
CS Tumor Size: 999 [Unknown]
CS Extension: 99 [Primary tumor cannot be assessed]
CS Lymph Nodes: 20 [Subcarinal lymph node involvement] based on positive level 7 biopsy, history of mediastinal lymphadenopathy and subcarinal "adenopathy" per CT.
