CS Extension--Pancreas: How do you code this field for a head of pancreas primary with involvement of portal and splenic veins? See Discussion.
The splenic artery/vein is only mentioned in the body and tail scheme; no mention is made of this site in the pancreatic head scheme.
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 54 [major blood vessels]. The portal vein is listed under code 54 for head of pancreas. The splenic vein branches from the portal vein.
CS Extension--Brain and CNS: How is CS Extension coded for a malignant meningioma that demonstrates extension into adjacent brain tissue?
For malignant brain tumors, code 60 represents extension into the meninges. Would code 60 be the correct code for extension from a malignant meningioma into brain tissue?
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 60 for malignant meningioma with extension to adjacent brain tissue.
According to the I&R, this section of CS was taken directly from SEER Summary Staging, since AJCC does not have a staging system for these tumors.
CS Lymph Nodes/CS Reg Nodes Eval -- Rectum: If the rectal tumor is not treated with a resection but on endoscopic ultrasound the patient is stated to have a lymph node above the primary tumor and the physician stages the case clinically as N1, should the CS Lymph Nodes field be coded to 30 [Regional lymph node(s), NOS] or 10[Rectal, NOS]? Should the evaluation field be coded to 0 [No lymph nodes removed. Evidence based on other non-invasive clinical evidence] or 1 [No lymph nodes removed. Evidence based on endoscopic examination.]? See Discussion.
Rectal primary:
5/04 sigmoidoscopy w/bx of rectal mass: adenocarcinoma. 6/04 Endoscopic ultrasound of rectal mass: invasion through wall but no definite invasion of prostate or seminal vesicles; 7.5mm lymph node located above tumor, no other enlarged lymph nodes detected. Patient did not have surgery. Physician staged lymph node involvement to clinical N1.
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 Lymph Nodes code 10 [Regional lymph nodes] based on the physician's N1. Assign code 10 because it is the lowest numerical CS code that corresponds to N1 in the scheme for rectum. Use the physician's assignment of TNM when the information in the medical record is incomplete or ambiguous. Code CS Reg Nodes Eval field 0 [No lymph nodes removed] for the case described above because there is no indication that N1 was assigned based on the endoscopic exam. The NI may be based solely on TNM documentation provided by the clinician and you do not know what the clinician used as the basis for the staging.
CS Extension/CS Mets at Dx--Pineal Gland: In Collaborative Stage, how is positive cerebral spinal fluid 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.Assign CS Mets at DX code 40 [Distant metastases] for a pineal gland primary with positive cerebral spinal fluid.
CS Eval/Surgery of Primary Site--Colon: When the only procedure performed is a polypectomy, if there is NO tumor at the margins, should CS TS/EXT-Eval be coded as 3 and the surgery coded as a polypectomy?
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 eval code 3. A polypectomy with no tumor at the margin meets the criteria for pathologic staging.
Code polypectomy in Surgery of Primary site in this case.
CS Extension--Prostate: Can the phrase "hard, fixed prostate" be interpreted as clinical extracapsular extension and coded to 50 [extension or fixation to other structures]? See Discussion.
Patient had a "hard, fixed prostate" with needle core bx positive for Gleason grade 4+5=9 adenocarcinoma extensively involving gland. PSA was 87.5. Lymphadenectomy showed 3 positive pelvic/obturator lymph nodes. No prostatectomy was done and no physician TNM staging documented.
Do we need a specific clinical description of other organs to which the prostate is fixed in order to code CS Clinical Extension 50, or does the statement "hard, fixed prostate" qualify? If not, how would we code extension for this seemingly advanced cancer?
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 extension code 50 [extension or fixation to adjacent structures] based on the term "fixed." Fixation to a particular structure(s) does not have to be specified in order to use code 50.
Do not use the statement "hard" to determine CS extension.
CS Extension--Corpus uteri: Can a suspicious cytology be used to code extension? See Discussion.
Endometrial primary confirmed by biopsy on 10/26/06. Pelvic washing on 11/14/06 was 'suspicious for malignancy.' Resection path the same day stated the primary tumor invades the inner 1/3 of the myometrium.
Can we use the pelvic washing cytology & code CS extension 61 or should CS extension be coded 12?
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 extension code 61 [cancer cells in peritoneal washings] for the case described above.
"Suspicious" is listed as a term indicating involvement. There is no exception noted for cytology reports. See page 122 of the 2007 SEER manual.
CS Extension--Retinoblastoma: When the degree of extension differs between the retinas, how is extension coded for simultaneous bilateral retinoblastoma?
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 the CS extension code that corresponds to the greatest level of extension seen in either eye, excluding information from enucleation.
Record extension based on enucleation in Site Specific Factor 1.
Record bilateral disease under laterality. For retinoblastomas, bilaterality is not a component or consideration for staging.
CS Tumor Size--Bladder: Is tumor size coded to 080 when the bladder mass is described as "greater than 8 cm in diameter"?
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.Based on the information provided above, code CS tumor size 080 [8 cm]. Code the information that is avaliable. Since size of tumor is not used to stage bladder cancer, an approximation is adequate.
CS Eval--Colon: When the surgical resection occurs after radiation or chemo, how is the tumor size/extension evaluation field coded when there is no mention of the tumor size or extension in the surgical resection pathology report? See Discussion.
6/30/04 CT Scan abd/pelvis: 7.5x7.2 cm large rectal mass with l cm nodular densities in perirectal region probably adenopathy; irregularity of perirectal soft tissue which could be due to tumor infiltration. 7/26/04 Patient has radiation therapy and 5FU. 10/19/04 LAR: MD Adenoca rectum with regional node mets (3/8).
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.Based on the information provided above, code CS Tumor Size and Extension from CT scan. Code CS TS/Ext eval 5 [Surgical resection performed with pre-surgical treatment...size based on clinical evidence].
Code CS lymph nodes using information from resection. Code CS Reg Nodes eval 6 [Regional LN removed...with pre-surgical treatment...based on pathologic evidence].
