Multiple Primaries (Pre-2007)--Thyroid: Would a papillary carcinoma of the right lobe of the thyroid diagnosed approximately 2 1/2 years after a papillary carcinoma of the left lobe be coded as a second primary? See Description.
8/31/1999: papillary carcinoma, left lobe thyroid, treated with lobectomy.
1/17/2002: papillary carcinoma, right lobe, treated with lobectomy, completion thyroidectomy.
For tumors diagnosed prior to 2007:
Yes, this is a second primary. The second papillary carcinoma was more than 2 months after the first and not specified as recurrent or metastatic.
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.
Histology--Lymphoma: What code is used to represent the histology "monomorphic post-transplant lymphoproliferative disorder [diffuse large B-cell lymphoma]"? See Description.
A 14 year old with a cadaver kidney transplant in 1994 for membranous glomerulonephritis presented in 6/26/03 with a right cervical LN with biopsy showing "lymph node involved by monomorphic post-transplant lymphoproliferative disorder (diffuse large B-cell lymphoma). Staging was done including a bone marrow which was negative, CSF negative. The oncologist on the case reduced the immunosuppression drugs with the final outcome being no sign of the lymphoma.
For cases diagnosed prior to 1/1/2010:Code 9680/36 [Diffuse large B-cell lymphoma]. This post-transplant lymphoproliferative disorder was diffuse large B-cell lymphoma. According to the World Health Organization, there are two types of post-transplant lymphoproliferative disorder. "Regular" post transplant lymphoproliferative disorder is not a neoplasm and is therefore not reportable to a cancer registry. The second type (sometimes called Hodgkin-like PTLD) is classified as a B-cell lymphoma, which means that it IS reportable.
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.
Date of Diagnosis/Diagnostic Confirmation: How are these fields coded when a physician statement of diagnosis predates a positive biopsy? See Description.
A mass seen on EGD with negative biopsy 12/28/01. Needle core biopsies 1/14/02 were diagnostic of GIST. Gleevec treatment was initiated 2/02, and in discharge summary 5/27/02, the physician says the GIST was diagnosed on EGD.
Code the date of diagnosis as 01/2002. Code the diagnostic confirmation as positive histology. EGD revealed a "mass." Biopsies of the "mass" seen on EGD were negative before January 2002.
Surgery of Primary Site--Breast: How is this field coded when a patient has a reduction mammoplasty (for macromastia) and within the pathology specimen there is an incidental finding of carcinoma?
Code this reduction mammoplasty to the code which best fits the amount of tissue removed. Read the operative report carefully. Code as a partial mastectomy, skin- nipple- areola-sparing mastectomy, or total (simple) mastectomy. Use text fields to record the details.
EOD/Surgery of Primary Site--Melanoma: If a melanoma primary site is other than skin, vulva, penis, or scrotum should these fields be coded using melanoma schemes? See discussion.
Should a melanoma of the cervix be coded using the melanoma or the cervix schemes for these fields?
For cases diagnosed 1998-2003: Use the EOD and surgery code schemes for cervix uteri. The EOD scheme for melanoma excludes melanoma of the cervix uteri. The surgery code scheme for skin excludes cervix uteri.
Multiple Primaries (Pre-2007)--Breast: Synchronous invasive right breast tumors. Ductal carcinoma, NOS in UIQ and Ductal carcinoma, tubular type in LOQ. Are these two primaries or a single primary coded to 8523/3?
For tumors diagnosed prior to 2007:
Code as two primaries, one 8500/3 [Infiltrating duct carcinoma] and one 8211/3 [Tubular carcinoma].
Apply the multiple primary rules first. These are synchronous right breast tumors with different histologies. Therefore, they are separate primaries according to rule 5.a on page 12 of the SEER Program Code Manual. ICD-O-3 histology code 8523/3 is NOT to be used to combine histologies from separate primaries; it is used for mixed histologies in a single primary.
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.
Multiple Primaries (Pre-2007)--Breast: For a patient with a remote history of lobular breast carcinoma, would a new diagnosis of lobular breast carcinoma with DCIS be a new primary, even though the physician designates it as recurrent? See Description.
A history of right breast lobular ca in 1991 treated with a partial mastectomy. Diagnosed 3/02 with "recurrent right breast ca" per physician; pathology in 2002 is lobular and DCIS.
Would the DCIS make this a new primary regardless of the physician's designation of 'recurrent' or is this the same primary?
For tumors diagnosed prior to 2007:
Accession as two breast primaries -- the first lobular ca in 1991; the second lobular and DCIS in 2002.
The differing histologies and the length of time between them negate the physician's designation as "recurrent" in this case.
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.
Primary Site: How is this field coded for a mass involving the gastroesophageal junction and lower third of the esophagus? See Description.
We have an EGD report describing an ulcerated and infiltrative circumferential non-bleeding 10 cm. mass of malignant appearance found at the gastro-esophageal junction and lower third of the esophagus. The mass caused a partial obstruction. Biopsies were taken from the the gastroesophageal junction and lower third of esophagus. Pathologic diagnosis: Adenocarcinoma. Would this be coded C26.8?
Search for a statement indicating the site of origin. If the site of origin cannot be determined, and there is evidence of Barrett's esophagus, code the topography in the example above to C15.5 [Lower third of esophagus]. If there is no evidence of Barrett's esophagus, assign code C16.0 [Gastroesophageal junction]. Either C15.5 or C16.0 would be preferable to C26.8, which is very non-specific and includes GI tract, pancreas and biliary tract.
EOD-Extension--Stomach: How is this field coded for a stomach primary that has metastases to "Sister Mary Joseph's Nodes?"
For cases diagnosed 1998-2003: For a stomach primary, code extension to 70 [Abdominal wall]. Sister Mary Joseph's nodule is a cutaneous umbilical metastasis most commonly from an intra-abdominal primary.
This rare form of cutaneous umbilical metastasis results from spread of tumor within the falciform ligament. The umbilicus is part of the abdominal wall.
