20110056 | Primary site--Heme & Lymphoid Neoplasms: What is the primary site for a post-transplant lymphoproliferative disorder (PTLD) diagnosed on a brain biopsy? See Discussion. | A patient was diagnosed in 6/2010 with PTLD by a brain biopsy. PTLD typically involves lymph nodes. Can the primary site for PTLD be coded to the brain? | For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Per Rule PH30, use the Heme DB to determine the primary site and histology when PH1-PH29 do not apply. Per the Abstractor Notes section in the Heme DB, PTLD commonly involves lymph nodes, GI tract, lungs, and liver. Although CNS involvement is rare, in solid organ recipients the CNS may be the only site of involvement or may be associated with multi-organ involvement. Code the primary site to C719 [brain, NOS] and the histology to 9971/3 [post-transplant lymphoproliferative disorder (PTLD)]

20110104 | Primary site--Heme & Lymphoid Neoplasms: Should the primary site be coded to C421 [bone marrow] or C770-C779 [lymph nodes] for an adult T-cell leukemia/lymphoma [9827/3] that presented with a positive bone marrow biopsy and involvement of lymph nodes and the lung? | For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph..
Code the primary site to the involved lymph nodes [C770-C779]. Per Rule PH 8, it indicates you are to code the primary site to the site of origin when lymph node(s) or lymph node region(s), tissue(s) or organs are involved. Note 2 further states that the bone marrow may or may not be involved. If the bone marrow is involved, code this information in the CS Extension field.
Per the Abstractor Notes section in the Heme DB, this is a systemic disease with widespread lymph node involvement as well as involvement of the peripheral blood. In addition, systemic involvement of extranodal sites (including lung) are often involved.

20110118 | Reportability--Colon: Is a polypectomy that is suspicious for invasive adenocarcinoma followed by a partial colectomy with no residual neoplasm reportable? See Discussion. |
08/28/2009 Cecum biopsy showed an adenomatous polyp with focal areas suspicious for invasive adenocarcinoma. SINQ 20071060 states a suspicious biopsy that is disproven by a subsequent surgical procedure is not reportable. That does not seem to apply in this case because the patient had a suspicious finding on a surgical procedure (polypectomy), followed by a second surgical procedure that was negative. Is it possible that the polypectomy removed the entire tumor and the suspicious diagnosis should be reported? |
This case is reportable. It is possible that the polypectomy removed the entire tumor. Invasive carcinoma in a polyp does not mean that is has invaded the stalk of the polyp. If the stalk is not invaded, all of the cancer may have been removed by a polypectomy. |

20110044 | MP/H Rules/Histology--Corpus uteri: What are the histologies for the primaries to be reported when the endometrium contains two separate tumors composed of adenocarcinoma with multiple differentiations as well as a separate small focus of clear cell carcinoma? See Discussion. |
The resected specimen showed, "Adenocarcinoma of endometrium with the following features: Histologic type: Endometrioid with squamous and focal clear cell differentiation. A second focus of endometrial adenocarcinoma is present in the fundus with admixed complex atypical hyperplasia in a polypoid, non-invasive mass. The second tumor is endometrioid with secretory differentiation. COMMENT: The tissue in between the two tumors is sampled, and contains foci of endometrial adenocarcinoma that is superficially present within the endometrium, as well as a small focus of clear cell carcinoma measuring 0.2 cm." Per MP/H rules M17, this is counted as multiple primaries because the histology codes differ at the third digit: 8323/3, 8382/3, 8310/3. The Multiple Primary rules make no reference to the histology tables. There is also no rule to ignore the in situ tumor. In addition, the histology table in the 2007 MP/H Rules Manual for Other Sites does not include "secretory differentiation" as a type of GYN malignancy. |
After consultation with our expert pathologist, the decision is report this case as a single primary. There was some confusion about how to apply the current MP/H rules to this pathology report given 1) the definition of M16 and M17 and 2) the likelihood for a single endometrial primary to present with several differentiations. According to our expert pathologist, "I would regard this case as a single endometrial primary with extensive endometrial involvement and several types of differentiation, all of which are seen in endometrial carcinomas." Next, the Multiple Primary and Histology Coding Rules Manual is the correct source for coding histology for cases diagnosed 2007 or later. The following steps are used to determine the histology code. Open the Multiple Primary and Histology Coding Rules manual. For an endometrial primary, use the Other Sites Histo rules to determine the histology code because endometrium does not have site specific rules. Start with the MULTIPLE TUMORS ABSTRACTED AS A SINGLE PRIMARY module, Rule H18. The rules are intended to be reviewed in consecutive order within the module from Rule H18 to Rule H31. You stop at the first rule that applies to the case you are processing. Code the appropriate combination/mixed code (Table 2) when there are multiple specific histologies. GYN malignancies with multiple types of adenocarcinoma have histology coded to 8323/3 [mixed cell adenocarcinoma] per rule H30. |

20110066 | Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are to be accessioned for a patient with a history of CLL undergoing chemotherapy who is subsequently diagnosed on a liver biopsy with diffuse large B-cell lymphoma (Richter transformation)? | For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Abstract the diffuse large B-cell lymphoma (Richter transformation) as a second primary per Rule M10. Rule M10 states to abstract as multiple primaries when a neoplasm is originally diagnosed as a chronic neoplasm (CLL) AND there is a second diagnosis of an acute neoplasm (the diffuse large B-cell lymphoma (Richter transformation)) more than 21 days after the chronic diagnosis.
"Richter transformation," also known as "Richter syndrome," is a term that indicates CLL has transformed to DLBCL. Richter syndrome is listed under the Alternate Names section in the Heme DB for DLBCL (9680/3).

20110042 | MP/H Rules/Histology--Testis: How is histology coded when the initial biopsies of retroperitoneal mass demonstrated non-seminomatous germ cell tumor, but after neoadjuvant chemotherapy the final diagnosis on the radical orchiectomy specimen demonstrated mature teratoma, NOS (not stated to be malignant)? See Discussion. | A large retroperitoneal mass was found on CT scan. A biopsy demonstrated non-seminomatous germ cell tumor. The biopsy was done at an outside facility. Neither the CT scan nor biopsy pathology report is available for review. Following neoadjuvant chemotherapy, the retroperitoneal mass decreased to 12 cm. Subsequently, the patient had a right radical orchiectomy. The final diagnosis per the pathology reports was a 3.5 cm mature teratoma (NOS, not stated to be "malignant") of right testicle. The patient then had resection of the retroperitoneal mass and biopsies. Pathology showed the "excision" specimen contained 6 benign lymph nodes and two of the "biopsy" specimens showed non-seminomatous germ cell neoplasm with IHC findings suggestive of a mix of embryonal carcinoma and a lesser component of yolk sac tumor. | This is a reportable case. Even though the pathology from the orchiectomy stated mature teratoma, NOS, the presence of lymph node metastases proves that this tumor is malignant. Code the histology as 9065/3 [germ cell tumor non-seminomatous].
The majority of germ cell tumors show the presence of multiple histologies. While the original tumor showed only mature teratoma, there were obviously yolk sac cells that were not detected on the sections taken from the primary tumor. Both teratoma and yolk sac are germ cell tumors. This explains why the pathologist gave you the diagnosis of germ cell tumor. The classification of "non-seminomatous" simply means that there was no seminomas present in the mixture of germ cell histologies. |

20110074 | First course treatment/Date therapy initiated--Breast: How is the Date of Initiation of Hormone Therapy field coded when a patient undergoes "Tamoxifen blunting" to achieve better MRI imaging after a biopsy but prior to definitive surgery which is followed by adjuvant Tamoxifen therapy? See Discussion. | Patients are prescribed two weeks of "Tamoxifen blunting" to achieve better MRI imaging after biopsy confirmation of an ER/PR positive breast carcinoma. The Tamoxifen is subsequently discontinued and the patient has definitive surgery. Following surgery, maintenance Tamoxifen is initiated. Which date should be recorded for the Date of Initiation of Hormone Therapy field? Is it the first date when Tamoxifen blunting started or the post-surgical date when maintenance Tamoxifen is initiated? | Use the post-surgical start date of maintenance Tamoxifen to code the Date of Initiation of Hormone Therapy field. The actual hormone treatment begins after surgery when Tamoxifen blunting was performed. The low dose administered prior to surgery does not affect the cancer. | 2011 |

20110006 | Reportability--Heme & Lymphoid Neoplasms: Are all stages of CLL reportable? See Discussion. | If a physician notes the patient has Stage 0 CLL (increasing leukocytosis), is this reportable? CLL Stage is not mentioned in the Hematopoietic Manual or Database, but internet research reveals CLL has five stages (Stage 0, I, II, III, and IV). | For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Yes. All stages of CLL are reportable. CLL has a unique staging system. The Heme DB and Manual do not address the issue of stage. Therefore, stage information is not reported in the Abstractor Notes section of the Heme DB.

20110032 | Primary site--Heme & Lymphoid Neoplasms: What primary site is coded for Langerhans cell histiocytosis (LCH) [9751/3] when it is limited to the skin? | For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Per Rule PH30, use the Heme DB to determine the primary site and histology when PH1-29 do not apply, In this case, code the primary site to C449 [Skin]. According to the Abstractor Notes section in the Heme DB, the solitary form of Langerhans cell histiocytosis (LCH) [9751/3] occurs less commonly than the multisystem form of the disease; but can appear in nodes, skin and lung. This is a solitary form of LCH. Code the primary site to skin [C449].

20110094 | Surgery of Primary Site--Breast: Is a "nipple sparing mastectomy" coded to 30 [subcutaneous mastectomy] or 40 [total (simple) mastectomy] if the nipple/areolar complex was not removed but the pathology specimen indicates some breast skin was removed? See Discussion. |
In the past, the SEER Manual indicated that code 30 [subcutaneous mastectomies], which captured nipple-sparing mastectomies, would rarely be used because it was not typically performed as treatment for a malignancy. This note was removed from the 2010 SEER Manual, Appendix C. Code 30 which now states, "A subcutaneous mastectomy is the removal of breast tissue without the nipple and areolar complex or overlying skin." More "nipple-sparing mastectomies" are now being performed at certain facilities.
Should the Surgery of Primary Site field be coded to 30 when a nipple-sparing mastectomy with reconstruction is performed, even if there is skin removal? Or, does the skin removal indicate that this is not a subcutaneous mastectomy, and therefore code 43 [Total (simple) mastectomy with reconstruction, NOS] applies? |
Code Surgery of Primary Site to 30 [Subcutaneous mastectomy] for this case.
Assign code 30 when the nipple and areolar complex are NOT removed. Assign code 40 (or higher) when the nipple and areolar complex ARE removed. |
