Reportability: Is a tubular adenoma reportable if the final diagnosis is "high grade atypia" and the diagnosis comment is "atypia limited to muscularis mucosa areas of pseudostratification [formerly qualifying for carcinoma in situ]"?

This case is not reportable.

The pathologist would need to include "carcinoma in situ" as part of the final diagnosis in order for this case to be reportable.

20081023 Histology: Must every word in the ICD-O-3 code definition appear in the diagnosis in order to assign that ICD-O-3 code? See Discussion. Is the diagnosis "Acute myeloid leukemia, M2" coded to Acute myeloid leukemia with maturation, FAB M2, NOS, (9874/3) or to Acute myeloid leukemia, NOS, (9861/3)?

For cases diagnosed prior to 1/1/2010:The general instructions for assigning histology codes are to code as precisely as possible. Acute myeloid leukemia with maturation is the definition of the FAB M2 category. A pathologist does not need to provide every word in the term associated with an ICD-O code; pathologists don't always talk that way. AML M2 is a very specific diagnosis and should be coded to 9874/3.

For cases diagnosed 1/1/10 and later, 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.

MP/H Rules--Lung: How do we interpret 'spiculated opacities?' How many primaries do we abstract for this patient? See Discussion.

Patient admitted for CT scan of chest. Impression: A small subpleural spiculated opacity is noted in the left upper lobe measuring 9.7x7.7mm. Right upper lobe spiculated nodular opacity measures 13.9x5.9mm. Right lower lobe scattered faint alveolar nodular opacities are noted. The lungs are otherwise clear. Abnormal soft tissue density mass is noted of the right hilum surrounding the distal main right pulmonary artery. Bronchoscopy/mediastinoscopy done: rare malignant cells present consistent with small cell carcinoma, specimen submitted as brushing of right bronchus intermedius. The tumor in the lymph node is metastatic small cell carcinoma. Patient discharged to hospice; died 5 weeks later.

Do the MP/H rules pertain only to the measured opacities in each lung and not to the RLL scattered faint alveolar nodular opacities? The right side was cytologically confirmed. But if we abstract the left lung, what is the histology...8041 or 8000?

For cases diagnosed 2007 or later:

Because there was cytologic confirmation of cancer, for this case only count the spiculated opacities as tumors. Abstract as a single primary using Rule M1. Note 2 under lung rule M1 applies to this case.

Code the histology as 8041 [small cell carcinoma] per rule H10.

20081125 Reportability: Is the following tumor(s) reportable? MRI of thoracic spine shows intramedullary hemangiomas in the bodies of T5 and T6.

Intramedullary hemangiomas in T5 and T6 are not reportable.

These benign tumors originate in the bone, not spinal canal, cord or dura. Benign tumors of the bone are not reportable.

According to WHO, the most common sites of involvement are the vertebral bodies, followed by craniofacial skeleton and long bones.

20081048 CS Lymph Nodes/CS Mets at Dx--Ovary: How are renal lymph nodes coded for ovary primaries?

This answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2.Code involvement of renal lymph nodes under CS Mets at Dx. Renal lymph nodes are not listed as regional lymph nodes for ovary; therefore, code involvement of renal lymph nodes under CS Mets at Dx.

Reportability--Brain and CNS: Is a cavernoma reportable as a benign brain tumor? See Discussion.

Cavernous hemangiomas are typically described as vascular malformations in the brain. Per a search of the literature, cavernoma, cavernous hemangioma and cavernous malformation are all synonymous. There is some controversy as to whether cavernomas are vascular malformations or tumors. Cavernous hemangioma (9121/0) has been assigned a code in the ICD-O-3. The other terms are not even listed. Benign brain guidelines indicate that named tumors that have been assigned an ICD-O-3 code are reportable. Would we report a lesion that is labeled cavernous hemangioma but not one that is labeled carvernoma? Are cavernous malformations of the brain to be reported as benign brain tumors? The MP/H guidelines for benign brain tumors do not include blood vessel tumors in chart 1.

Are the following tumors reportable? If so, what is the primary site?

Example 1: Patient admitted for resection. Clinical diagnosis is left temporal cavernous hemangioma. Path diagnosis is cerebral cortex and white matter showing cavernoma.

Example 2: Patient admitted for resection with clinical diagnosis of parietal cavernous hemangioma. Path shows A-V malformation.

Example 3: Patient had T4 spinal tumor removed. Path showed cavernous angioma.

Reference: I&R 18109 and 23460

Cavernoma is a reportable benign brain tumor. According to our pathologist consultant, cavernoma is synonymous with cavernous hemangioma.

Examples

1. Reportable. Primary site - C710 [cerebrum]

2. Not reportable. Path dx disproves clinical diagnosis.

3. Not reportable. Not a brain tumor.

20081043 MPH rules--Rectum: How is the number of primaries to be determined when a treatment plan has been completed, but it is not possible to determine whether there was a disease-free interval between occurrences? See Discussion.

Patient diagnosed with adenocarcinoma of the rectum in March 2006, underwent chemo and radiation therapy as treatment. Patient seen in April 2007 for surveillance colonoscopy. HPI stated patient underwent chemorad with good results. Colonoscopy showed "persistent" disease. Abdominal perineal resection was done in May 2007. Path showed adenocarcinoma of the rectum.

Keeping in mind that we are not to use a clinical statement for determining recurrences, is the April 2007 occurrence counted as a new primary?

For cases diagnosed 2007 or later:

Do not abstract the 2007 events as a new primary. "Persistent disease" indicates there was never a disease free interval.

20081083 Multiple primaries--Lymphoma: Is mediastinal large B-cell lymphoma followed by classical Hodgkin lymphoma reportable as one or two primaries? See Discussion. Diagnosed 06/06/2006 with mediastinal large B-cell lymphoma, 9679/36. On 05/10/2007, another mediastinal lymph node biopsy done and the diagnosis was recurrent malignant lymphoma, classical Hodgkin's. A Hematopatholgy Consultant states, "it appears likely that the preceding mediastinal diffuse large B-cell lymphoma and the current classical Hodgkin's lymphoma are clonally related and represent different manifestations of the same entity. One might also place this in the spectrum of 'mediastinal gray zone lymphoma' described by Dr. Jaffee and colleagues."

For cases diagnosed prior to 1/1/2010:Report this case as two primaries. Report non-Hodgkin lymphoma followed by Hodgkin lymphoma as separate primaries.

According to the Table of Single and Subsequent Primaries for Hematologic Malignancies, mediastinal large B-cell lymphoma and Hodgkin disease are "D" - Different disease processes.

For cases diagnosed 1/1/10 and later, 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.

20081108 CS Extension--Pancreas: How is this field coded for a head of pancreas primary with involvement of the inferior vena cava?

This answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2.Assign CS extension code 54 [Blood vessel(s) major]. The inferior vena cava is one of the major blood vessels.

The inferior vena cava is located just behind the head of the pancreas. The hepatic artery, the superior mesenteric vessels and the portal vein are nearby.

20081056 MP/H Rules--Lung: In reference to lung, SINQ 20071028 states "'nodule' is not an equivalent term for tumor, mass, lesion, or neoplasm." However, slide 5 for the MPH lung section of "Beyond the Basics" states "we use the words 'mass, nodule and lesion' interchangeably." Which is it?

For cases diagnosed 2007 or later:

For the purpose of applying the Lung MP/H rules, the word "Nodule" can be used interchageably with "Tumor," "Mass," "Lesion" and "Neoplasm." HOWEVER, this does NOT apply to casefinding or staging.

This revision will be added to the next version of the MP/H rules. Sinq question 20071028 will be revised.
