20200029 | Systemic/Surgery Sequence: The note associated with code 4 in Systemic Treatment/Surgery Sequence in the 2018 SEER Manual says: Code 4 is intended for situations with at least two episodes or courses of systemic therapy. Does this mean two different types of systemic therapy before and after surgery? See Discussion. |
For example, chemotherapy and immunotherapy administered first, followed by surgery, then immunotherapy and hormone therapy after surgery. Or is code 4 used for two administrations of chemotherapy before surgery and two more courses after surgery? |
Assign code 4 for the example you describe. Code 4 also applies to cases with one course of chemotherapy before surgery and another course after surgery. |

20200009 | First course treatment/Surgery of Primary Site--Corpus uteri: Is an omentectomy performed with a hysterectomy for an endometrial primary site recorded under Surgery of Other Site? See Discussion. |
Per SEER 20140003, an omentectomy is not recorded under Surgery of Other Site when performed with a hysterectomy for an endometrial primary. Is this still correct? CoC appears to have different guidelines stating in a forum that an omentectomy is coded in data item Surgical Procedure to Other Site. I would like to confirm SEER guidelines. Is this one of those unique situations that SEER and STORE differ? Our state follows SEER guidelines and would like to communicate the appropriate rules to our facilities. |
Continue to record an omentectomy performed with a hysterectomy under Surgery of Primary Site and not as a separate procedure under Surgical Procedure of Other Site. The guidance In SINQ 2014003 and 20091118 is unchanged. |

20200006 | Reportability--Retina: Is a diagnosis of retinal astrocytoma reportable? See Discussion. |
There is no specific ICD-O-3 code for a which resulted in abstractors assigning the malignant astrocytoma, NOS code. These lesions were previously called but we are seeing the new terminology more frequently. |
Report retinal astrocytoma. The WHO Classification of Tumors of the Eye, 4th edition, lists astrocytoma, NOS as 9400/3 with astrocytic hamartoma of the retina as a synonym. You may receive a site/type edit (IF25) which can be overridden. The changes in terminology, codes, etc. proposed in WHO 4th Ed Eye book were implemented for cases diagnosed 1/1/2018 forward. Apply this to retina astrocytomas and do not accession cases diagnosed with this histology prior to 1/1/2018. |

20200072 | Solid Tumor Rules (2018)/Multiple Primaries--Breast: How many primaries are accessioned when there are multiple synchronous/non-contiguous tumors when one tumor is metaplastic carcinoma (with carcinoma No Special Type (NST) or lobular carcinoma) and another tumor is strictly carcinoma, NST? See Discussion. |
Is an M rule needed to address multiple tumors and Note 2 in Table 3? Does Note 2 in Table 3 apply when multiple tumors exist and one tumor contains only ductal carcinoma? The M Rules currently confirm that a metaplastic carcinoma (whether it is involved with ductal or lobular) and a separate ductal carcinoma are separate primaries because these histologies are on different rows in Table 3 (separate primaries per M14). There is no specific rule regarding metaplastic carcinomas in the Multiple Tumors (M Rules) module, so presumably, the presence of a separate ductal carcinoma is not lumped into Note 2 in Table 3 for metaplastic carcinoma. However, the note is confusing when there are multiple tumors involved because it appears to the registrars there are two options for coding the histology. To some registrars, the rules indicate it does not matter if the tumor is predominantly ductal carcinoma as long as some percentage of metaplastic carcinoma is present, code histology to metaplastic carcinoma. For other registrars, the presence of solely a ductal carcinoma in a second tumor is a separate primary from the separate metaplastic carcinoma. The M rules and Note 2 need to clarify this issue to promote consistency. This question was prompted from preparing SEER*Educate coding exercises. We will use the answer as a reference in the rationales. |
The term "mixed" implies a single tumor comprised of metaplastic carcinoma or variants of metaplastic and duct or lobular. The metaplastic histology is coded regardless of whether it comprises the majority (greater than 50% of the tumor). M13 is the only rule specific to metaplastic and is in the single tumor module. This implies a single tumor with both histologies. When there are multiple tumors, one with metaplastic or a subtype/variant of metaplastic and another with a histology listed on a different row, continue to the Multiple Tumors module. M13 applies and there are two primaries. We will add "single tumor" to the note in Table 2 in the next update. |

20200058 | Surgery of Primary Site/Surgery Codes, NOS--Pancreas: What exactly is an extended pancreatoduodenectomy? Must the entire pancreas be resected in order to use code 70? What minimal requirements must be met to use code 70? How should a Whipple with cholecystectomy, partial omentectomy, common hepatic excision, portal vein resection, and lymphadenectomy be coded? |
According to our research, a pancreaticoduodenectomy (PD) includes an en bloc resection of the pancreatic head, the common bile duct, the gallbladder, the duodenum, the upper jejunum, the distal portion of the stomach and the adjacent lymph nodes. The extended PD procedure includes extended lymphadenectomy, extended organ resection, and extended vascular resection and reconstruction. Code 70 could be assigned without the entire pancreas being resected. A Whipple procedure removes the head of the pancreas, duodenum, stomach and gallbladder and part the common bile duct. The portal vein resection is probably part of the common bile duct excision. If the omentectomy was performed for treatment of this primary, record it in "Surgical Procedure of Other Site." Record the lymphadenectomy in the lymph node data items. |

20200008 | Solid Tumor Rules (2018)/Multiple primaries--Corpus uteri: How many primaries are accessioned for patient with a minimally invasive endometrial adenocarcinoma arising in a polyp in 2001, followed by a metastatic poorly differentiated clear cell carcinoma of gynecologic (GYN) origin in 2019? See Discussion. |
The patient has a history of a minimally invasive endometrial adenocarcinoma that was low grade and confined to an endometrial polyp in 2001. The patient underwent a total abdominal hysterectomy/bilateral salpingo-oophorectomy (TAH/BSO) that entirely removed the tumor at that time. Almost 18 years later, the patient had a left inguinal mass excision that was, Carcinoma of gynecologic origin, consistent with clear cell carcinoma. No other disease was found, the physician never indicated whether this was felt to be metastatic from the previous, low grade adenocarcinoma or not. It was only noted as, an unusual malignancy of the left lower quadrant and inguinal region of gynecologic origin. No further information was available in the medical record or from the physician on follow-up. Although neither the Solid Tumor Rules nor the MPH Rules (still in use for the Other Sites schema) apply to metastasis, given the differences in histology and behavior of these two tumors (i.e., minimally invasive, low grade disease diagnosed in 2001 vs. higher grade, more aggressive tumor in 2019) should the current clear cell carcinoma of GYN origin really be the same primary as the 2001 endometrial adenocarcinoma? |
Abstract a multiple primaries using 2018 Other Sites Solid Tumor Rule M10 as these tumors are more than one year apart. This represents endometrioid adenocarcinoma (8380/3 of C541) and 18 years later, clear cell Carcinoma (8310/3 consistent with GYN (C579) primary). |

20200040 | Reportability--Skin: Is pseudomyogenic hemangioendothelioma (PMH) reportable with morphology code 9133/3? See Discussion. |
According to the literature, PMH is a low-grade malignant vascular neoplasm of different tissue planes including skin and soft tissue. However, the references also state: PMH is a cutaneous tumor that behaves in an indolent fashion. There is no indication that this was a malignant diagnosis. 12/3/18 Foot, left skin lesion, punch biopsy: Superficial squamous epithelium demonstrating hyperkeratosis and fragments of keratin debris, no tumor seen. Foot, left skin lesion, punch biopsy: Pseudomyogenic (epithelioid sarcoma-like) hemangioendothelioma, see note. NOTE: The submitted immunohistochemical slides were reviewed. Positive and negative controls reacted appropriately. The tumor cells demonstrate immunoreactivity to CK AE1/AE3 and CK7. The CD31 immunoreactivity described in the report cannot be confirmed as only the positive control is submitted for review. The tumor cells are negative for desmin, CD45, CD68, S-100, CD34, SMA, CD20, and HHV8. The proliferative index via Ki-67 is approximately 10%. The morphology (described below) and immunohistochemistry performed are compatible with a pseudomyogenic hemangioendothelioma. 12/4/18 Final Pathologic Diagnosis: Foot, left bone lesion, biopsy: Pseudomyogenic (epithelioid sarcoma-like) hemangioendothelioma, see note. Note: The patient's imaging findings were reviewed in conjunction with this case, revealing numerous lytic lesions of the tibia, fibula, talus, tarsal, metatarsal, and phalangeal bones. Additionally, as per the medical record, also reviewed in conjunction with this case, there are lesions of the skin. Thus, an extensive immunohistochemical panel was performed in an attempt to support the morphologic findings in this case, which were morphologically similar to the patient's skin biopsy. The tumor cells demonstrate strong immunoreactivity to pancytokeratin (CK AE1/AE3) and vimentin with moderate immunoreactivity to Fli-1. The tumor cells demonstrate weak immunoreactivity to epithelial membrane antigen. INI-1 is retained. There is focal immunoreactivity to CD31 although this is limited to the edges of the tissue fragments. The tumor cells are negative for HHV-8, CD34, smooth muscle actin, CK8/18, desmin, CD99, and Bcl-2. The combination of morphologic (see below for microscopic description) and immunohistochemical findings are consistent with pseudomyogenic hemangioendothelioma. Fresh tissue was submitted for karyotype analysis at the time of intraoperative consultation; however, it revealed only a normal appearing male karyotype. Thus, molecular confirmation was sought. The original slides and a paraffin block were submitted for FOSB rearrangement analysis, as pseudomyogenic hemangioendothelioma is known to have recurrent rearrangements with FOSB. Additional immunohistochemistry performed at (FACILITY) demonstrating immunoreactivity for ERG, supporting a vascular origin for this neoplasm. Fluorescence in situ hybridization demonstrated that 13% of the cells examined show FOSB rearrangement. While this FISH probe is for investigational purposes, the above findings support the diagnosis of pseudomyogenic hemangioendothelioma. |
Do not report PMH. The WHO Classification of Skin Tumors lists pseudomyogenic hemangioendothelioma as a borderline malignancy (9138/1). Borderline malignancies of the skin are not reportable. |

20200060 | First Course Treatment/Reportability: Are there situations for which a case with a class-of-case code in the 30's should be reported to the central registry? We know these are not reportable to the CoC, but should they be reported to the central registry? See Discussion. |
Example: 3/22/2017-26 year old white female seen in the emergency room with abdominal pain. Patient was diagnosed about a month ago with breast cancer. Impression: menstrual pain. In this example the patient is newly diagnosed with breast cancer, but the second hospital does not treat or diagnose the patient; pain management for a separate condition is received only. Is this patient reported due to the history of active disease? |
Work with your central registry to determine which cases they require you to report. In general, any case still undergoing first course of treatment, even if not given at your facility, should be reported to the central registry. Many central registries will appreciate knowing that the patient was seen at your facility to update date last seen and other data items. |

20200014 | Solid Tumor Rules (2018)/Histology--Brain and CNS: How are histology and primary site coded when a resection of a spine, designated intramedullary lesion, shows primary intramedullary melanocytoma? See Discussion. |
Patient has a resection labeled as: Spine, designated intramedullary lesion. The Final Diagnosis is: Melanocytic neoplasm with features most consistent with primary intramedullary melanocytoma. The Diagnosis Comment states: The overall immunophenotypic and morphologic impression is a primary central nervous system melanocytoma. The ICD-O-3 lists melanocytoma, NOS histology code as 8726/0, but does not provide a site-associated code. If the ICD-O-3 is used, the histology would be 8726/0 and the primary site presumably would be C720 since the tumor was specifically described as being intramedullary (i.e., within the spinal cord medulla). Table 6 (Solid Tumor Rules, Non-Malignant CNS Equivalent Terms and Definitions) does not list either an intramedullary melanocytoma or melanocytoma (NOS). However, Table 6 does include meningeal melanocytosis 8728/0 and meningeal melanocytoma 8728/1. If Table 6 is used and the histology is coded 8728/1, then the primary site would presumably be C701 per the ICD-O-3 site-associated listing for this histology (C709). |
Code primary site to spinal meninges (C701) and histology to meningeal melanocytoma (8728/1). According to the WHO Classification of Tumors of the Central Nervous System, 4th ed., primary melanocytic neoplasms of the central nervous system are diffuse or localized tumors that presumably arise from leptomeningeal melanocytes. Benign or intermediate grade lesions are termed melanocytomas. Meningeal melanocytoma is defined as a well-differentiated, solid, and non-infiltrative melanocytic neoplasm that arises from leptomeningeal melanocytes. Most arise in the extramedullary, intradural compartment at the cervical and thoracic spine though they can be dural-based or associated with nerve roots or spinal foramina. |

20200023 | Solid Tumor Rules (2018)/Histology--Endometrium: Is the histology for a serous carcinoma, high-grade endometrial primary 8441/3 (serous carcinoma) or 8461/3 (high grade serous carcinoma)? See Discussion. |
Path report reads: 7/15/2019 A. Endometrium, curettings: Serous carcinoma, high grade. B. Endometrial polyp, curettings: Serous carcinoma, high grade. If coded to 8461/3, according to AJCC, this would not be an ideal code (since it is outdated). Also, endometrium is not included in the suggested site codes for 8461/3 according to the 8/22/2018 ICD-O-3 update. |
Code histology for this endometrial primary to serous carcinoma 8441/3. Capture "high grade" in the grade field as instructed in the grade coding manual. "High grade serous carcinoma" has specific clinical and histopathologic features found in ovarian tumors. |
