20021105 Grade, Differentiation: Do we code to the highest grade even when no grade is given at the time of initial diagnosis, but a grade is obtained on tissue removed after non-surgical treatment has occurred? See discussion.

1. In 2000 a pleural fluid aspirate had no grade. Pt treated with chemo. In 2000 a BSO diagnosed high grade papillary serous adenocarcinoma of the ovary.

2. In 1993 a prostate bx had no grade. Pt treated. In 2001 prostate bx revealed a Gleason's 4+3.

Code the grade at the time of initial diagnosis (if the specimen is from the primary site) or to the grade identified as part of a first course of cancer-directed surgery to the primary site. When different grades are specified for tissue pathologically reviewed from the primary site before and after treatment, code the higher grade. This is true even if the higher grade is obtained while the pt is still undergoing first course of cancer-directed therapy.

1. Code the Grade to 4 [high grade], if the grade information from the BSO specimen represents the grade associated with primary site surgical specimen. Even though the grade was obtained after first course of cancer-directed therapy started, it was obtained during first course of cancer-directed therapy.

2. Code the Grade to 9 [Cell type not determined, not stated or not applicable]. Grade was obtained well after the first course of cancer-directed therapy ended.

20021050 EOD-Extension--Pancreas: If the tumor involvement for a case falls between two different regional extension codes, should we code to the lesser of the two codes or should we code extension as unknown? See discussion.

Example 1: CT scan description: Mass in the head of the pancreas. The duodenum is "surrounded" by tumor. Should we code extension to 40 [peripancreatic tissue extension, NOS] or 99 [unknown] because the extension code could be further than 40. It could be 44 [extension to duodenum].

Example 2: CT scan description: Mass in region of pancreatic head and "root" of superior mesenteric artery consistent with pancreatic cancer. Should we code extension to 40 [peripancreatic tissue extension, NOS] or 99 [unknown] because the extension code could be further than 40? It could be 54 [extension to major blood vessels].

For cases diagnosed 1998-2003:

In both examples, code the EOD-Extension field to 40 [peripancreatic tissue extension, NOS]. Choose the lowest of a known possible extension code over an unknown code.

20020012 MP/H Rules/Histology--Breast: What code is used to represent the histology "ductal carcinoma in situ and invasive lobular carcinoma"? See discussion. Is the histology coded to the combination code of 8522/3 (ductal and lobular) or to the invasive component 8520/3 (lobular)?

For cases diagnosed 2007 or later:

Assuming ductal carcinoma in situ and invasive lobular carcinoma are present in a single tumor, code 8520/3 [Infiltrating lobular carcinoma, NOS].

Using the 2007 MP/H rules for breast, the single tumor invasive and in situ carcinoma module, start and stop at rule H9 and code the invasive histology.

 2002
20021119 Radiation--Choroid: How do you code treatment involving a "radioactive iodine plaque" for choroidal melanomas?

Code the Radiation field to 2 [Radioactive implants]. Codes for radiation are based on HOW the radiation is delivered, rather than the particular type of radioactive material used.

Radioactive eye-plaques contain rice-sized iodine-125 or palladium-103 seeds which emit low energy photons. They are sewn or glued into the eye. The plaque remains for 5 to 7 days and is then removed.

 2002
20021046 Behavior Code/EOD-Extension--Bladder: If an in situ lesion of the urinary bladder involves the von Brunn nests, is it still in situ? See discussion.

Von Brunn nests: Compact, rounded aggregates of urothelial (transitional) cells in the lamina propria, with or without connection to the surface epithelium.

Urothelial (transitional cell) carcinoma in situ...may involve von Brunn nests...

Histologic Typing of Urinary Bladder Tumours, Second Edition, WHO, pp 12 & 21

For cases diagnosed 1998-2003:

Code the Behavior Code and the EOD-Extension field according to the pathology report.

If the pathology report states the tumor to be noninvasive or in situ, whether or not von Brunn nests are involved, code behavior as 2 [in situ] and extension as in situ.

If the tumor is described as invasive and involves the von Brunn nests, code the EOD-Extension field to 15 [invasive tumor confined to subepithelial connective tissue] because code 15 includes extension to the lamina propria and von Brunn nests are within the lamina propria.

20021011 Reportability/Histology (Pre-2007)/Behavior Code/Primary Site: How would you code these fields for a case in which an infant presents with a skin rash, enlarged spleen, palpable abdominal mass, inconclusive bone marrow biopsy and a skin biopsy that was positive for "Langerhans cell histiocytosis"? See discussion. The pathologist states, "I would consider this case a malignancy, although it does not always behave as such. Lesions in babies often act in a malignant manner."

For tumors diagnosed prior to 2007:

If the pathologist states this is a malignancy, the case is reportable. Code the Histology field to 9751/3 [Langerhans cell histiocytosis, NOS] and change the Behavior Code from 1 to 3. Code the Primary Site field to skin [C44._].

For tumors diagnosed 2007 or later, refer to the MP/H rules. If there are still questions about how this type of tumor should be coded, submit a new question to SINQ and include the difficulties you are encountering in applying the MP/H rules.

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.

20021048 EOD-Lymph Nodes: If chemotherapy or radiation is given prior to the excision of an involved lymph node, should the size of the metastasis within the lymph node be coded from the subsequent surgical pathology report? See discussion. For several sites, the size of the metastasis in an involved lymph node is integrated into the EOD-Lymph Node field. Should the size of the metastasis mentioned on the pathology report be ignored if the patient received radiation or chemotherapy prior to having the lymph node removed?

For cases diagnosed 1998-2003:

Record the size of a lymph node metastasis described in the pathology report for cases that had pre-surgical treatment. However, if both the pre-treatment and post-treatment size of the lymph node metastases are available, use the larger size when coding the EOD-Lymph Node field.

Primary Site/Surgery of Primary Site--Lymphoma: What codes are used in these fields when both regional lymph nodes and an extra-nodal site are involved with lymphoma and there is not a clear statement from the clinician as to the primary site? See discussion.

In our registry, we code the primary site for such cases to the extra-lymphatic site if there is one extra-nodal site involved with disease and the patient does not have disseminated involvement of multiple extra-nodal sites. Is this correct? Example: A patient with a submandibular lymphoma and involved nodes undergoes a salivary gland excision and a modified radical neck dissection yielding 100 nodes.

For cases diagnosed prior to 1/1/2010:Code the Primary Site to C08.0 [submandibular gland] and use the surgery code schemes that apply to that site (Parotid and Other Unspecified Glands). Physiologically, lymphoma cells in regional lymph nodes do not "back-flow" into the extralymphatic organ to involve it secondarily. As a result, the primary site is usually the extralymphatic organ with regional lymph node involvement. Do not be afraid to code an extralymphatic site as primary when that site and its regional nodes are involved.

If the lymph nodes are not regional to the extra-nodal involved site and the primary site cannot be determined, code the primary site to C77.9 [Lymph node, NOS].

For cases diagnosed 2010 forward, refer to the Hematopoietic and Lymphoid Neoplasm Case Reportability and Coding Manual and the Hematopoietic Database (Hematopoietic DB) provided by SEER on its website to research your question. If those resources do not adequately address your issue, submit a new question to SINQ.

20021183 Primary Site--Head & Neck: What site code is used to represent the following head and neck primary where there is not a clear statement of primary site? See discussion.

6/29/02: PE: 2-3 cm mass in the posterior pharynx that seems to arise from the right side of back of tongue.

6/29/02 CT soft tissue of neck: 3 cm right sided oropharyngeal mass, possibly arising from right tongue mass. There is near occlusion of airway at this level.

7/3/02 Excision of oropharyngeal tumor: Palpated mass could clearly be felt coming off the right lateral tongue in approximately the mid portion of the tongue near the tonsillar base.

 Code the Primary Site field to C02.9 [tongue, NOS], based on the information provided. 2002
