20110058 | Date of diagnosis/Flag: Will the Date of Diagnosis Flag ever be used if the instructions for coding Date of Diagnosis are followed? See Discussion. | If an abstractor follows the instructions for coding the Date of Diagnosis and can at least estimate a year of diagnosis, in what scenario will the Flag be used?
Per the 2010 SEER Manual,
Page 49 Date of Diagnosis, second paragraph, "Regardless of the format, at least Year of diagnosis must be known or estimated. Year of diagnosis cannot be blank or unknown." The manual gives the following guidelines for coding diagnosis date/flag:
Page 50, Coding Instructions: 3. If no information about the date of diagnosis is available a. Use the date of admission as the date of diagnosis b. In the absence of an admission date, code the date of first treatment as the date of diagnosis.
Page 51, Coding Instructions: 9. Estimate the date of diagnosis if an exact date is not available. Use all information available to calculate the month and year of diagnosis.
Page 53, Date of Diagnosis Flag, Coding Instructions: Always leave blank. Date of Diagnosis will always be a full or partial date recorded. |
The date of diagnosis flag should always be blank. | 2011 |

20100066 | MP/H Rules/Multiple Primaries--Breast: How many primaries should be accessioned if two tumors are present in the same breast, a 1.7 cm colloid carcinoma and a 1.5 cm colloid carcinoma with infiltrating ductal carcinoma? See Discussion. | If a patient has two masses in the same breast with different histology codes and different sizes, should this be accessioned as two primaries? Or should this be a single primary based on the largest tumor size or numerically higher histology code?
|
For cases diagnosed 2007 or later, abstract this case as two primaries. Mucinous/colloid carcinoma of the breast is rare. The first tumor describes (1.7 cm) fits this criteria because the pathologist simply says mucinous carcinoma. The diagnostic criteria for mucinous carcinoma is that pools of extracellular mucin make up at least 1/3 of the volume throughout the tumor mass. If focal areas are not at least 33% mucinous, the designation is a mixed mucinous/ductal. That fits the second tumor (1.5 cm).
For this case, you must get the histology codes for both tumors in order to use the Multiple Primary rules. Per H14 the first tumor is coded mucinous carcinoma [8480/3]. Per H17 the second tumor is coded duct carcinoma mixed with any other carcinoma [8523/3]. Now go to the MP rules. Per M12 abstract this case as multiple primaries because the ICD-O-3 histology codes are different at the second and third digit. |

20190071 | First course treatment/Surgery of Primary Site--Rectum: Please provide the correct surgery code for a laparoscopic transanal abdominal transanal (TATA) procedure with bilateral salpingo-oophorectomy (BSO) for rectal cancer following neoadjuvant chemotherapy. See Discussion. |
IMPRESSION/PLAN: Patient is a previously healthy middle aged woman with a diagnosis of adenocarcinoma of the rectum, clinical stage II (T3N0M0). We will proceed with a neoadjuvant course of radiation and concurrent chemotherapy (5-FU) to maximize local regional control and survival, and hopefully facilitate a sphincter-sparing resection in the future. The primary tumor and the pelvic nodes at risk will receive 4500 cGy delivered over 25 treatments. The primary tumor will subsequently receive an additional 1080 cGy delivered over 5 treatments, for a cumulative dose of 580 cGy. PATHOLOGY: Adenocarcinoma of the rectum, clinical stage II (T3N0M0). The patient is referred by (dr) for a neoadjuvant course of chemoradiotherapy. HPI: Patient presented recently with rectal bleeding and a change in bowel habits. Colonoscopy revealed an ulcerated mass located 4.0 cm above the anal verge. A biopsy was positive for invasive well-differentiated adenocarcinoma that arose from a tubular adenoma. A staging work-up demonstrated no evidence of metastatic disease. |
Code Surgery of Primary Site as 40, Pull through WITH sphincter preservation (colo-anal anastomosis). The TATA procedure is described as transanal abdominal transanal proctosigmoidectomy with coloanal anastomosis. We are assuming the BSO was not releated to treatment of the rectal cancer. Do not code it. You may document it in a text field. |

20220046 | First Course Treatment/Immunotherapy--Other Therapy: Should IMC-A12 (Cixutumumab) be coded as Immunotherapy/Biological Response Modifier (BRM) treatment? See Discussion. |
IMC-A12 (Cixutumumab) is listed as a BRM agent in SEER*Rx, but the Remarks section indicates it should be coded as Other Therapy until there is FDA approval. It is unclear if FDA approval was ever given for this agent. We are mainly seeing it given for prostate primaries. |
Code Cixutumumab as Other Therapy. Cixutumumab is still in clinical trials and not approved by FDA yet. Though it is classified as an immunotherapy agent, it is not approved. |

20210060 | Reportability/Histology--Thymus: Is a 2021 diagnosis of a type A microscopic thymoma reportable? See Discussion. |
ICD-O-3.2 lists microscopic thymoma as benign (8580/0) and thymoma, type A as malignant (8581/3). January 2021: Left central neck node dissection for thyroid carcinoma with thymic tissue showing an incidental type A microscopic thymoma, described as a small (<0.2 cm) focus. Diagnosis comments further indicate this is morphologically consistent with a microscopic thymoma (type A). |
Report this case as type A thymoma. We consulted an expert physician and his advice on this specific case is to interpret it as a malignancy and report. Use text fields to record the details of this case. |

|
20230029 | Primary Site--Skin: Are perianal skin primaries within 5 cm of the anus coded as perianal skin (C44.5) or anus (C21.0). See Discussion. |
ICD-O-3 tells us that perianal skin is C445 and we do not capture basal or squamous cell skin cancers in our registry. The AJCC manual stages perianal skin cancers within 5 cm of the anus with the anus chapter. We cannot AJCC stage them as an anus if we are not capturing them as C445. I realize we do not code a site in order to stage. We have been following the reportability rules and not capturing. Is this correct? I do not see this addressed in the new Other Sites Solid Tumor Rules. |
Code primary site based on the site of origin as determined by the physicians. If the physicians state the site of origin is anus, code anus; the same as with skin. As you state, squamous cell cancer of sites coded to C44 is not reportable. The AJCC instruction for physicians to stage perianal neoplasms within 5 cm of the anus using the Anus chapter does not change cancer registry instructions for coding primary site, nor does it affect cancer registry reportability instructions. |

20190076 | Primary Site/Brain and CNS: How is primary site coded when the ICD-O-3 provides a sub-site-associated morphology code and the only information available to code primary site for a particular diagnosis indicates a non-specific/not otherwise specified (NOS) site code? See Discussion. |
ICD-O-3 Rule H states to use the topography code provided when a topographic site is not stated in the diagnosis. This topography code should be ignored if the tumor arose in another site. For the following brain and central nervous system (CNS) examples, should the suggested sub-site codes be assigned based on the histology, or should the primary sites be coded as C719 (posterior fossa or suprasellar brain) since the only information available was a tumor in these non-specific sites? Example 1: Resection of a posterior fossa tumor proved medulloblastoma, WNT-activated. Although medulloblastoma has a site-associated code in the ICD-O-3 (C716, cerebellum), the only information available is that this was a posterior fossa tumor (C719). Example 2: Resection of a suprasellar brain tumor proved pineoblastoma. The pathologist labeled this as a brain tumor, suprasellar. Although pineoblastoma has a site-associated code in the ICD-O-3 (C753, pineal gland), the only information available is that this was a suprasellar brain tumor (C719). |
If possilbe, ask the physician(s) about the exact site of origin. If it is not possible to obtain more information, the information in the medical documentation takes priority over ICD-O-3 Rule H, even when that results in a less specific topography code. |

20190033 | Update to current manual/Neoadjuvant therapy/Pathologic tumor size--Breast: When a patient with invasive breast cancer is started on neoadjuvant therapy and at surgery is found to have only residual in-situ disease, do we record the size of the in-situ tumor for Pathologic Tumor Size? See Discussion. |
I understand that we are to record the Clinical Tumor Size in Tumor Size Summary because of the neoadjuvant therapy, but the SEER manual does not address what to record in the Pathologic Tumor Size after neoadjuvant therapy. Would we record 999 or the size of the in-situ tumor in the Pathologic Tumor Size field? Will there ever be a new data item added or changes to this current data item? By recording the Patholigic Tumor Size this way, there currently will not be any way to compare tumor size clinically versus after neoadjuvant therapy and assessing the response. |
Note: this is an update to the 2018 SEER manual. Assign 999 in Pathologic Tumor Size when neoadjuvant therapy has been administered. We can explore the possibility of another data item in the future. |

20170062 | Race, ethnicity: How do you code race for someone from New Zealand? |
I recently did a presentation on coding the data item Race. In my presentation I discussed understanding geography help code race in some circumstances. One of the slides demonstrates how large Polynesia is and what Pacific islands are found in Polynesia, such as, Tahiti, Samoa, and even Hawaii, all of which have their own codes. Someone in the audience asked "How do you code New Zealand? Upon some research, New Zealand is not listed in Appendix D of the SEER coding manual. We could code them 01-White. But research shows there is a very large indigenous population. Technically, New Zealand is located within the boundaries of Polynesia - Code 25 (Polynesian). |
If the only information you have on race is that the person is from New Zealand, code race as white. This is based on the instructions for Australia, the closest neighbor to New Zealand as no other guidance was found. |

20180013 | Reportability--Brain and CNS: Are tuberous sclerosis cancers found in the brain reportable? See Discussion. |
I have searched ICD-O-3 for a histology listing but could not locate. I also searched the SEER Inquiry database for possible answers, but none were found. The patient underwent a pediatric MRI of the brain of which final impression was: 1) Subependymoma nodules, cortical tubers, and SEGAs are seen bilaterally consistent with tuberous sclerosis. |
SEGA (Subependymal giant cell astrocytoma) is reportable if diagnosed in 2004 or later. Tuberous sclerosis complex (TSC) is not a neoplasm and is not reportable. SEGA is a neoplasm that commonly occurs in TSC patients. Refer to the reportability instructions on pages 5-7 in the SEER manual, https://seer.cancer.gov/manuals/2016/SPCSM_2016_maindoc.pdf |
