20091103 | Reportability/Ambiguous Terminology--Prostate: Is a prostate biopsy that states "highly suspicious for, but not diagnostic of adenocarcinoma, suggest another biopsy" reportable? | Do not report. "Not diagnostic of" means that while the pathologist is seeing some features that resemble cancer, there are not enough features to feel comfortable making an unquestionable diagnosis. Watch for another biopsy of the patient in the next 3-6 months. The statement "not diagnostic of" overrules the "highly suspicious" statement. | Prostate | N/A | 2009 | |

20010001 | EOD-Clinical Extension--Prostate: Note 8 of the clinical EOD scheme for prostate states, "B1, Small, discrete nodule(s)<1.5 cm, and B2 Nodule(s)>1.5 cm ... " Does Note 8 still apply for cases diagnosed 1998 or later? |
For cases diagnosed 1998-2003:
Note 8 in the EOD scheme does not apply because nodule size does not apply in the 5th or 6th edition of TNM. |

20010158 | EOD-Pathologic Extension--Prostate: Does capsular invasion (code 32) take priority over apex extension (code 34) on prostate primaries? See discussion. | On prostatectomy, adenocarcinoma involves left apex and also left mid lobe where it focally invades capsule. Do we code extension to 34 - the highest numerical code, or to 32 to capture the capsular invasion? Do codes 33 and 34 represent a subset of code 31, and would code 32 represent greater tumor involvement? | For cases diagnosed 1998-2003:
Code the EOD-Pathologic Extension field to 32 [Invasion into (but not beyond)prostatic capsule] when there is both capsular and apex invasion of the prostate.
Although numerically lower, code 32 takes precedence over codes 33 [arising in the apex] and 34 [extending to the apex]. Codes 33 and 34 are "subsets" of code 31 [Into prostatic apex/arising in prostatic apex]. |

20240017 | EOD 2018/Prostate Pathologic Extension--Prostate: Is a pathology report from a prostate biopsy/transurethral resection of the prostate that states "with intraductal spread" extraprostatic/extracapsular extension or localized? |
Code as a localized, intracapsular tumor as ductal carcinoma in situ does not invade. Intraductal spread is describing the neoplasm spreading through the acinar/ductal cells in the prostate specimen. It is an in-situ type of spread and not invasive but almost always presents with an invasive tumor. |

20210054 | EOD 2018/EOD Primary Tumor/Tumor Size--Clinical--Prostate: How is Tumor Size--Clinical coded when there is an incidental finding of prostate cancer on prostatectomy for another reason? See Discussion. |
SEER*RSA states EOD Primary Tumor should be coded to 800 for an incidental finding of prostate cancer on prostatectomy for other reasons. The SEER Manual states to assign code 000 for Tumor Size--Clinical when EOD Primary Tumor is coded to 800; however, the definition for Tumor Size--Clinical indicates clinical classification is composed only of diagnostic workup prior to treatment. If there is no clinical workup for an incidental finding of prostate cancer, code 000 does not seem appropriate (does not meet criteria for clinical classification). Code 999 seems more appropriate for incidental findings during surgery for other reasons. The SEER Manual does not provide this exception in the current instruction. |
Assign code 000 for Tumor Size--Clinical when EOD Primary Tumor is coded 800 (No evidence of primary tumor). Code 000 indicates no tumor was found since there was no clinical workup to identify this incidentally found cancer. This is a special instruction for cases coded 800 in EOD Primary Tumor. Text fields can be used to record details. |

20000516 | Diagnostic Confirmation--Prostate: How do we code this field when there is an elevated PSA, no other work-up and there is a clinical diagnosis of adenocarcinoma? | Code the Diagnostic Confirmation field to 5 [positive laboratory test/marker study] to indicate the diagnosis is based upon an abnormal PSA tumor marker if the physician uses the PSA as a basis for diagnosing prostate cancer. | Prostate | Diagnostic confirmation | 2000 | |

20240011 | Solid Tumor Rules/Histology--Other Sites: Other Sites Table 2 (Mixed and Combination Codes) requires site designations; can sites be added? See Discussion. |
There are multiple possible entries (rows) for a tumor with a neuroendocrine component and non-neuroendocrine component, but these rows do not specify which primary sites are applicable. Row 1 (Combined small cell carcinoma, 8045) seems applicable to a prostate primary, but not to a GI primary since GI primaries are now generally referred to as MiNENs (mixed neuroendocrine non-neuroendocrine tumors), but Table 2 does not provide any instructions regarding how to determine the difference between 8045 and 8154 (or 8244). For SEER Workshop Case 03 (mixed prostate case), many users selected 8154 or 8244 as the mixed histology code per Table 2, but these histology codes are not listed as applicable in Table 3 (Prostate Histologies). Per the WHO Blue Books, these histologies are not listed as applicable to the prostate. How are registrars to determine the correct mixed code without site designations, especially if they don't have access to the WHO Blue Book or to a pathologist who may be able to clarify the codes? |
Sites may be added to certain combinations when indicated by ClinCORE review for Cancer PathCHART. Please note some sites were added in the 2024 update as a result of PathCHART review. A newly-formed Solid Tumor Editorial Board and its subgroups are currently working to evaluate the Solid Tumor Manual and make recommendations on ways to improve the structure and formatting of the manual and its content. Follow the rules and instructions in the Other Sites STRs when assigning combination histology codes. Histology Coding Rules Use the Histology Coding Rules when assigning combination codes. Coding Histology Information Use this section that includes the mixed histology (Table 2) and site-specific histology tables (Tables 3-23) for one or more histologies within a single tumor. Do not use this section in place of the Histology Coding Rules. While site-specific histology tables, based on current WHO Classification of Tumors books, have been added to Other Sites STRs, not all site groups have individual histology tables; coding may require the use of ICD-O and updates. The histology tables in Other Sites STRs include additional coding instructions and notes to assign the correct ICD-O code when appropriate. The tables are not meant to be all-inclusive; rather they are intended to address difficult coding situations to facilitate the assignment of the correct histology code. Table 2: Mixed and Combination Codes Instructions Once you have identified the histology terms and have been instructed to use Table 2 by the Histology Coding Rules, compare the terms in the diagnosis to the terms in Column 1. When the terms match, use the combination code listed in Column 2. Use adenocarcinoma mixed subtypes 8255 as a “last resort” code. |

20170070 | Primary Site/Histology--Urinary: Is a urethral lesion showing intraductal carcinoma of the prostate reportable? What is the primary site and histology code? See discussion. |
Pathology report diagnosis: Urethral lesion: Intraductal carcinoma of the prostate, see microscopic. Clinical Information: Urethral Lesion/Hematura. Microscopic Description: The biopsy shows dilated ductal structures filled with anaplastic epithelium showing areas of comedo-type necrosis. The tumor cells have enlarged nuclei prominent nucleoli and mitoses are identified. Surrounding benign prostatic tissue is also present. Immunostains show that the tumor cells stain for PSA, PSAP, P504s but are negative for GATA-3. The other components of the PIN 4 stain CK5/14 and P63 stain the basal cells surrounding the tumor confirming the intraductal nature of the process. Intraductal carcinoma should not be confused with high grade PIN as the former is usually associated with high grade invasive tumor. Is this C619 and 8500/2? |
The primary site is prostate, C619, and the histology is intraductal carcinoma, 8500/2. Further workup on this case is likely. If more information is received, review this case and update if needed. |

20020044 | Terminology/EOD-Extension--Prostate: How does SEER define the prostatic "apex"? See discussion. |
Some pathologists define the prostatic apex as including the bottom third of the prostate whereas others regard only the bottom-most portion of the gland to be the apex. |
SEER defines the apex as being the bottom-most portion of the gland. Apex means "narrowest part," which in the prostate would be the bottom-most portion of the gland. |

20010025 | Surgery of Primary Site--Prostate: What treatment code is used to represent prostate carcinoma treated with "high intensity focused ultrasound" (HIFU)? | For cases diagnosed 1998 and later:
Code the Surgery of Primary Site field to 17 [Other method of local tumor destruction]. HIFU uses focused energy to destroy tissue. It is classified as a surgical procedure. |
