EOD-Size of Primary Tumor--Cervix: When both a depth and diameter of the tumor are provided and the description of the diameter is provided in a range, how do you code the size of the primary tumor? See discussion.
Path states "microscopic focus of endocervical glands considered invasive adenoca...maximum depth of that focus measures approximately 2 mm. Maximum diameter of that focus measures 3-4 mm."
What size would be coded for this case: 999, 002, 003, or 004?
Code the EOD-Size of Primary Tumor field to 004 [4 mm]. Code the diameter dimension in the EOD-Size of Primary Tumor field and the depth dimension iin the EOD-Extension field. Code the largest number associated if a range is provided for the diameter of the invasive tumor.
If the size of the diameter had not been mentioned, the EOD-Size of Primary Tumor field would have been coded to 001 [microscopic focus or foci only], which ignores the size associated with the depth dimension of the tumor.
EOD-Size of Primary Tumor--Colon: When an adenocarcinoma is stated to be arising in an adenoma and the "tumor size" stated in the final pathologic diagnosis is the same size as the mass described in the gross description, should we assume that the entire polyp has been totally/near totally replaced by tumor and code the tumor size stated in the final path diagnosis?
For cases diagnosed 1998-2003:
Code the EOD-Size of Primary Tumor field as stated by the pathologist in the final pathologic diagnosis. If the size of the tumor is the same as the size of the polyp, assume the polyp was completely replaced by tumor.
Reportability: Is "Castleman's Disease" reportable?
For cases diagnosed prior to 1/1/2010:Castleman's Disease is not reportable to SEER. Synonyms for this disease process include: Castleman-Iverson Disease, benign giant lymph node hyperplasia, and angiofollicular mediastinal lymph node hyperplasia. Castleman's Disease is a rare disorder characterized by non-cancerous growths that may develop in the lymph node tissue throughout the body. The plasmacellular form of this disease may progress to lymphoma or plasmacytoma.
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.
EOD-Extension--Head & Neck: How do you code extension for a supraglottic larynx primary with "pre-epigolottic space" invasion?
For cases diagnosed 1998-2003:
Code the EOD-Extension field to 65 [Pre-epiglottic tissues]. Extension to "pre-epiglottic space" is equivalent to extension to "pre-epiglottic tissue."
Reason for No Cancer-Directed Surgery: Could you explain why this field would be coded to 1 [Cancer-directed surgery was not recommended] or 2 [Contraindicated due to other conditions] for a case that presents with distant metastasis at diagnosis?
For cases diagnosed 1998-2002:
Code the Reason for No Cancer-Directed Surgery field to 1 [Cancer-directed surgery was not recommended] for patients who present with either a primary site or histology for which surgery is not a standard treatment. Also use code 1 for those patients who present with distant disease for a primary site that is typically treated surgically. Patients with distant metastasis typically do not have surgery performed as part of first course of treatment.
Code 2 [Contraindicated due to other conditions] is used when surgery would normally be recommended for the site (given the current stage of the tumor) but other medical conditions pose too much of a risk for the patient to undergo surgery.
Primary Site: How do we code the primary site for a malignancy that occurs in parenchyma located in an ectopic site? See discussion.
1. Patient presented with a subcutaneous nodule in right axilla. Pathologic impression by initial and reviewing pathologists is that the lesion represents a breast adenocarcinoma arising in ectopic mammary parenchyma. Subsequent breast biopsies were negative.
2. Patient presented with right branchial cleft cyst. The pathologist states the cyst is a primary thyroid adenocarcinoma arising in an ectopic focus of thyroid tissue. The subsequent total thyroidectomy is negative.
Code the primary site to the location of the malignancy.
1. Code the Primary Site field to C76.1 [Axilla NOS].
2. Code the Primary Site field to C10.4 [Branchial cleft].
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.
Grade, Differentiation--Bladder: What codes are used to represent this field for the four bladder cases described in the discussion section that have a combination of grades mentioned in the pathology reports? See discussion.
1) Final path diagnosis: papillary transitional cell carcinoma, high grade. Micro description states: High grade, poorly differentiated carcinoma.
2) Well to moderately differentiated papillary transitional cell carcinoma, grade 1-2/3.
3) Urothelial carcinoma, high grade (poorly differentiated, grade 3 of 3).
4) High grade papillary urothelial carcinoma (papillary transitional cell carcinoma, grade 3 out of 4).
For cases diagnosed January 2004 and forward:
1) Grade 4. High grade is coded 4. Code the grade stated in the final diagnosis.
2) Grade 3. Grade 1-2/3 is coded 3. Use the three-grade conversion table in the 2004 SEER manual.
3) Grade 4. Grade 3 of 3 is coded 4. Use the three-grade conversion table in the 2004 SEER manual.
4) Grade 3. "Grade 3 out of 4" is coded 3 and is more precise than "high grade."
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.
