"Resection, periampullary duodenum: Gangliocytic paraganglioma, with metastasis to one large periduodunal lymph node. Six other small lymph nodes negative. COMMENT: The primary tumor in the duodenum is made up mainly endocrine cell component. This component appears to have metastasized to a periduodenal lymph node."

Patient was seen in 2009 at Hospital A for bone pain and was found to have metastatic adenocarcinoma. A paraffin block specimen was sent to BioThernostics for THEROS CancerTYPE ID Molecular Cancer Classification Tests. The results came back with a 94% likelihood that the urinary bladder was the primary site. No scans were done on the abdomen or pelvis.

The patient was then sent to Hospital B for radiation to the bones and chemotherapy (Carboplatin and Taxol). The patient died within 6 months.

According to Hospital A, the primary site is bladder based on the molecular study report. Hospital B says this is an unknown primary. Which is correct? Do we take primary site from these tests, even when no clinical correlation is documented?

Patient was diagnosed with Myeloid Sarcoma (granulocytic sarcoma) by chest wall biopsy. This is an extramedullary manifestation of acute leukemia and is not in the bone marrow (bone marrow is negative).

How should primary site be coded? The Heme DB states that almost any part of the body can be involved. It also states to not code primary site to C421. In this case the only involvement is the chest wall [C493]. However, use of the primary site code C493 triggers an edit error questioning this site/histology combination. If the primary site is coded to C421 [bone marrow], there is no edit error. Please explain the site code and rationale.

In a patient is diagnosed 1/29/08 with an invasive grade 3 of 3 papillary urothelial cell carcinoma arising in the depth of a calyx in mid portion of kidney, the primary site was coded C659 [Renal pelvis]. In 6/1/09 a TURBT showed three separate lesions on the right side of the bladder. The final diagnosis was high grade urothelial carcinoma in-situ with three tumors, the largest being 7mm. Per rule M8, the renal pelvis primary and subsequent bladder tumors are the same primary. Would the primary site be changed to C689 [Urinary system, NOS] when the bladder tumors were identified? Or is C689 only coded if more than one primary site is involved at diagnosis?

Per SINQ 20091021 and 20021151, GIST cases are not reportable unless they are stated to be malignant. A pathologist or clinician must confirm the diagnosis of cancer. There are cases that are not stated to be malignant in the pathology report or confirmed as such by a clinician; however, these cases do have information that for other primary sites would typically be taken into consideration when determining reportability. The final diagnosis on the pathology report for all 16 cases is "GIST." The additional comment(s) for each of the 16 different cases is reported below. Are any of the following cases reportable?

1) Pathology report indicates that the bulk of the tumor is submucosal. It extends through the muscularis propria and abuts the serosa.

2) Pathology report states tumor extends to serosal surface of transverse colon, but not into muscularis propria. CD 117 and CD 34 are positive.

3) Pathology report indicates that tumor invades through the gastric wall to the serosal surface.

4) Pathology report indicates that tumor invades pericolic fat tissue.

5) No further information in pathology report, however, scans indicate omental caking.

6) No further information in pathology report, however, scans indicate hepatic metastases. Hepatic metastases are not biopsied.

7) Tumor stated to be unresectable and extends into pancreas. Chemotherapy given.

8) Pathology report states tumor is low to intermediate grade and involves serosal (visceral peritoneum).

9) Tumor size is 17.5 cm. Pathology report states "malignant risk".

10) Pathology report states tumor "into muscularis propria" or tumor "involves muscularis propria" or "infiltrates into muscularis propria".

11) Pathology report states, "high malignant potential; omentum inv by tumor." It is not stated in path report or final diagnosis to be malignant GIST.

12) Pathology report states that tumor arises from wall of small bowel and extends into thin serosal surface.

13) Pathology report states minimal invasion of lamina propria; does not penetrate muscularis propria.

14) Pathology report states, "high mitotic activity >10/50 HPF; high risk for aggressive behavior; moderate malignant potential."

15) Pathology report states tumor size is >5 cm. Intermediate risk for aggressive behavior; CD117+ KIT exon 11+.

16) Pathology report states "high risk of malignancy."

On 11/23/09 the patient had urine cytology diagnosis "positive for malignancy, favor low grade papillary urothelial carcinoma." On 12/28/09, the bladder biopsy showed "urothelial neoplasm of low malignant potential."

SINQ 20081086 only addresses the example of a positive FNA/biopsy followed by a negative resection. Would the previous decision hold for this case when a positive fine needle aspiration biopsy is followed by only a negative biopsy?

1/27/10 BM biopsy: CML BCR/ABL+ FISH positive for BCR/ABL and cytogenetics showing the t(9;22)q34q11.2 translocation. Treated with Imatinib. 4/15/10 BM biopsy: B-acute lymphoblastic leukemia (Blast phase of CML). Would the term "blast phase of CML" indicate the 4/15/10 bone marrow biopsy showed CML or would a new primary be abstracted with histology coded 9811/3 [B lymphoblastic leukemia/lymphoma, NOS]?

Applying rule M10, this is a new primary, but note 2 states transformations are defined in the Heme DB. The Abstractor Notes section indicates CML has three phases: chronic, accelerated, and the blastic phase or blast crisis. The accelerated phase can last weeks to months. In the chronic phase the involvement is usually limited to blood, bone marrow and spleen although the liver may be infiltrated. During the blastic phase, lymph nodes and tissue may be involved. The blastic phase is a disease progression from the chronic phase. The disease, however, remains the same histology, chronic myelogenous leukemia.
