20240058 | Summary Stage 2018--Ovary: What is the summary stage for an ovarian primary in 2024, in which the ovary capsule was ruptured with surgical spill? See Discussion. |
In this case, the surgeon ruptured the ovarian tumor to drain it prior to removal causing the surgical spill. Regional lymph nodes are negative and there is no metastasis. The capsule was then noted as ruptured on pathology. Does it matter if the surgeon was the one who ruptured the capsule? Would the stage change if the surgeon intentionally ruptured the capsule to drain the tumor intraoperatively causing some surgical spill? The scenarios of an intentional and not intentional rupture are not specified in SEER Summary Stage 2018. |
Code SEER Summary Stage 2018 to Localized, Code 1. Per consult with AJCC and noted in the Primary Peritoneal Chapter in AJCC 8th edition, an intraoperative rupture is coded as a surgical spill. A capsule rupture is when the capsule ruptures prior to the surgery (Summary Stage Regional, Code 2). |

20190032 | Summary Stage 2018--Lung: Are ground-glass lung nodules coded as distant for Summary Stage? See Discussion. |
Chest x-ray: Multifocal pneumonia in left lung; possibility of masses in left lung not excluded. Chest CT: 4 large ground-glass masses in LUL (largest 46mm); beginning of Tree-In-Bud appearance in LUL; 2 small ground-glass nodules in right lung. Lung LUL biopsy: Adenocarcinoma, Solid Predominant. No further information as patient did not want to discuss treatment options. Per the AJCC book and CAnswer Forum, multifocal classification should be applied equally whether the lesions are in the same lobe OR in different ipsilateral lobes OR contralateral lobes, cT2b(m), cN0, cM0. |
Do not assume that ground glass presentation is consistent with a neoplasm. There are numerous causes of a ground glass lung condition such as sarcoidosis or pulmonary fibrosis. A ground glass lung opacity may also be observed in conditions such as alveolar proteinosis, desquamative pneumonitis, hypersensitive pneumonitis, and drug-induced or radiation-induced lung disease. If an area of ground glass opacity persists in the lung, it is usually classified as an adenocarcinoma, a classification that ranges from premalignant lesions to invasive disease. This is in line with AJCC that states to stage based on the largest tumor determined to be positive for cancer. To Summary Stage the case example provided, ignore the lesions in the contralateral lung (do not assume that they are malignant). There are multiple lesions in the left lung, but once again, do not assume that those not biopsied are malignant. This leaves us with the lesion confirmed to be malignant, making this a Localized (code 1) tumor. |

20140065 | Summary Stage 2000--Melanoma: How should Summary Stage 2000 be coded for 2014+ diagnosed melanoma cases with satellite nodules or in transit metastases? See discussion. |
The SEER SS (SSS) 2000 Manual indicates satellite nodules (NOS or less than/equal to 2cm from primary tumor) are regional by direct extension (code 2) and in-transit metastasis (satellite nodules greater than 2 cm from primary tumor) are coded as involvement of regional lymph nodes (code 3). However, CSv0205 indicates mapping for satellite nodules/in transit metastasis (coded in CS LN) was changed to Regional, NOS (code 5). There are no definitions listed for code 5 in the SSS 2000 Manual.
Our staff independently code SSS 2000. Should we code the existence of satellite nodules and in transit metastases according to the current definitions in the SSS 2000 Manual or using the mapping information from CSv0205? |
Code the existence of satellite nodules and in transit metastases according to the current definitions in the SSS 2000 Manual. Do not use the mapping information from CS to code SSS. |

20160052 | Summary Stage 2000--Lymphoma: How is SEER SS2000 coded for an ocular adnexal lymphoma when it extends from the primary site to adjacent sites that are still orbital structures? See Discussion. |
In this case, the lymphoma arose in the posterior orbit and the primary site was coded as C696 (orbit, NOS). The mass directly extended to at least one "adjacent" site, the lacrimal gland. Should SS2000 be coded to 1 (localized) or 5 (regional, NOS) when an ocular adnexal lymphoma arises in the posterior orbit and extends to involve the lacrimal gland? Although both the posterior orbit and the lacrimal gland are parts of the orbit, they have separate ICD-O-3 topography codes. Should extension to multiple sites within the orbit be classified as localized disease?
The issue is what constitutes "adjacent" structures for a tumor that arises in the orbit. In an article published by the Indian Journal of Opthamology it states, "According to the Ann-Arbor staging system, lymphoma confined to the orbit is designated as Stage I, involvement of adjacent structures (sinuses, tonsil and nose) makes it Stage II." Does SEER agree with this definition of "adjacent" structures? Or are the lacrimal gland, ciliary body, retina, conjunctiva and/or choroid "adjacent" structures for a lymphoma stated to arise in the posterior orbit? |
Assign SEER SS2000 code 5 (Regional, NOS) for a lymphoma of orbit extending to lacrimal gland. In SEER SS2000, this is Stage IIE: Direct extension to adjacent organs or tissues. |

20031095 | Summary Stage 2000--Colon: How should this field be coded for involvement of "pericolonic fat, NOS" when there is no mention of whether the fat is sub-serosal or supra-serosal? See Description. |
In the summary staging manual pericolic fat is listed under regional direct extension with no mention of whether sub-serosal or supra-serosal. According to our report the pathologist must specify whether involvement of pericolonic fat is of subserosal or supraserosal fat. If involvement of pericolonic fat was not specified as such, this should be localized vs regional direct extension. |
Code Summary Stage as 2 [Regional by direct extension only]. In Summary Stage 1977 and 2000, pericolic fat is listed under Regional Direct Extension. If there is no indication by the pathologist that the involved fat is subserosal, code as Regional Direct Extension. |

20200047 | Stage-related Data Item/Lymphovascular Invasion--Ovary: The 2018 SEER Program Coding and Staging Manual states that LVI is coded 8 (Not applicable) for Ovary (Schema 00551). What is the reason for having lymphovascular invasion (LVI) coded "8" for Ovary? See Discussion. |
This direction is also in SEER*RSA for Ovary. Researching a possible explanation for this, we found that LVI is an independent predictor of progression and survival in patients with primary epithelial ovarian cancer at early stage but not at advanced stage. However, studies also recommend that routine evaluation of LVI in ovarian cancer is highly recommended in daily practice. |
The coding instructions were developed and implemented in concert with the AJCC Cancer Staging Manual, 7th edition, and updated with the 8th edition as per the 2018 STORE Manual and were based on sites where distinguishing between lymphatic/small vessel invasion and venous/large vessel invasion was not medically appropriate. SEER required LVI for penis and testis cases only beginning in 2016; sites other than penis or testis are coded 8 unless required by state or central registries. The list for use of code 8 has been changed for 2021 and will no longer include Ovary. |

20220036 | Solid Tumors Rules/Histology--Head and Neck: How is histology coded for head and neck primaries when a tumor is diagnosed as an invasive squamous cell carcinoma with multiple subtypes? See Discussion. |
Example Case 1: 2022 mobile tongue tumor biopsy shows squamous cell carcinoma, basaloid non-keratinizing type. Example Case 2: 2022 base of tongue mass biopsy shows squamous cell carcinoma, basaloid non-keratinizing type, p16 positive. Table 5, Note 2 (Head and Neck Equivalent Terms and Definitions) instructs us to code non-keratinizing squamous cell carcinoma which is p16 positive to 8085 (Squamous cell carcinoma HPV-positive), ignoring the non-keratinizing subtype. Does p16 or HPV positivity also take priority over multiple subtypes (basaloid non-keratinizing type)? |
Assign 8083/3, basaloid squamous cell carcinoma (BSCC), in both examples. It is more important to capture the variant than to code 8085 or 8086. WHO Classification of Head and Neck Tumors, 5th ed., states that BSCC is a distinctive form of SCC, characterized by prominent basaloid morphology, squamous differentiation, and aggressive behavior. Some primary sites capture p16 status as a Site Specific Data Item; you may record the p16 results when that is the case. |

20240021 | Solid Tumor Rules/Reportability/Histology--Digestive Sites: Is a diagnosis of “high grade dysplasia” (not specified to be squamous or glandular) reportable for esophagus, stomach, and small intestine for cases diagnosed beginning in 2024? If so, how should histology be coded? See Discussion. |
SEER Program Coding and Staging Manual indicates high grade dysplasia of esophagus, stomach, and small intestine are reportable. The ICD-O-3.2 does not include “high grade dysplasia” as equivalent to “high grade squamous dysplasia.” If reportable, would high grade dysplasia (NOS) that originates in the stomach and small intestine default to 8148/2, while esophageal high grade dysplasia (NOS) default to 8077/2? |
Report these high grade dysplasia of the following organs as stated below. Stomach: Assign code 8148/2 glandular intraepithelial neoplasia, high grade using the Other Sites Solid Tumor Rules, Table 6: Stomach Histologies and as described in the WHO Classification of Digestive Tumors, 5th edition. Small intestine and Esophagus: Assign code 8148/2 glandular intraepithelial neoplasia, high grade, using the Other Sites Solid Tumor Rules, Other Sites Histology Rules, Rule H4/H26. The following note is listed for both of these rules. Note: This list may not include all reportable neoplasms for 8148/2. See SEER Program Coding and Staging Manual or STORE manual for reportable neoplasms The Other Sites Solid Tumor Rules, Table 5: Esophagus Histologies and Table 7: Small Intestine and Ampulla of Vater Histologies will be updated to reflect this code as time permits. |

20200030 | Solid Tumor Rules/Multiple primaries--Lung: How many primaries should be accessioned for the following patient scenario? 1) 09/2014 Left upper lobe (LUL), unifocal, localized acinar adenocarcinoma (8550/3) treated with lobectomy. 2) 04/2016 Right lower lobe (RLL), unifocal, localized acinar adenocarcinoma (8550/3) treated with wedge resection. 3) 04/2019 (within 3 years, but masked full date) Left lower lobe (LLL), unifocal, non-small cell carcinoma (8046/3) with brain metastasis. See Discussion. |
Rule M4 does not seem to apply because Note 1 defines clinically disease free to mean no evidence of recurrence in the same lung on follow-up. Patient had been disease free in the left lung after 09/2014 diagnosis. The 04/2019 diagnosis was in a different lung than the 4/2016 diagnosis. The next applicable rule is either M11 or M14 depending on how we should compare the new 2019 tumor: to the most recent prior tumor in 2016 or to both prior tumors. |
Abstract three primary tumors according to the 2018 Solid Tumor Rules as follows : 2014: LUL, single primary using M2 2016: RLL, multiple primary; abstract second primary using M11 (different lung) 2019: LLL, multiple primary after reapplying rules using M4 when comparing to the same lung in 2014. Abstract this tumor as it has been more than three years and it appears the patient had no clinical evidence of disease in the left lung until 2019. |

20180079 | Solid Tumor Rules/Multiple primaries--Breast: How many primaries should be abstracted when papillary carcinoma is identified in two biopsies and a subsequent lumpectomy identified invasive ductal carcinoma with multifocal ductal carcinoma in situ (DCIS)? See Discussion. |
The right breast ultrasound shows a 1.4 cm mass at 8 o'clock and a separate mass .6 cm at 7 o'clock (site code for both C50.5). Pathology report: Right 8 o'clock core needle biopsy fragments of intracystic noninvasive papillary carcinoma (8504/2), right 7 o'clock core needle biopsy fragments of intracystic noninvasive papillary carcinoma (8504/2). Then, another facility performs a right breast lumpectomy (operative note not available). Outside Facility: Right breast lumpectomy pathology shows invasive ductal carcinoma .6cm (8500/3) multifocal DCIS .5cm greatest dimension tumor site right breast NOS. Should we use Rule M12-Abstract multiple primaries when separate/non-contiguous tumors are on different rows in Table 3 in the Equivalent Terms and Definitions. Timing is irrelevant. Note: Each row in the table is a distinctly different histology. So would this be two primaries C50.5 (8504/2) and C50.9 (8500/3)? |
Abstract as multiple primaries using Breast Solid Tumor Rule M12 as these are separate, non-contiguous tumors on different rows in Table 3. |
