Reportability: Is penile intraepithelial neoplasia, differentiated type, reportable? See discussion.
Foreskin circumcision shows: Penile intraepithelial neoplasia, differentiated type (differentiated PeIN). If reportable, how would the histology and behavior be coded? Is this behavior /2?
For cases diagnosed 2018 and later
Differentiated penile intraepithelial neoplasia (differentiated PeIN), is reportable (8071/2).
Please note: Penile intraepithelial neoplasia, grade 3 (PeIN 3) is also reportable to SEER (C600-C609, 8077/2).
MP/H Rules/Histology--Head and Neck: What is the histology code for salivary duct carcinoma of parotid gland?
Code salivary duct carcinoma to invasive ductal carcinoma (8500/3). Salivary duct carcinoma is an aggressive adenocarcinoma which resembles high-grade breast ductal carcinoma according to the WHO Classification of Tumors of Head & Neck.
MP/H Rules/Histology--Breast: How should histology be coded for a breast primary with resection final diagnosis of "Ductal carcinoma with neuroendocrine features?" See Discussion.
Should the histology for "Ductal carcinoma with neuroendocrine features" be coded to 8500 (Ductal carcinoma, NOS) or 8574 (Adenocarcinoma with neuroendocrine differentiation)?
Code the histology to 8574/3 for Ductal carcinoma with neuroendocrine features.
Ductal carcinoma is also called "invasive breast carcinoma of no special type." WHO classifies Invasive breast carcinoma with neuroendocrine differentiation as 8574/3.
First course treatment/Chemotherapy: Is metronomic chemotherapy coded as chemotherapy?
Code metronomic chemotherapy as chemotherapy. Metronomic chemotherapy, also referred to as low-dose metronomic (LDM) chemotherapy, is an emerging cancer treatment approach which administers relatively low doses of traditional chemotherapy drugs over a long period of time and without ‘breaks’ in treatment. By using lower doses this method of treatment minimizes the side effects of traditional chemotherapy.
Birthplace/Place of birth, country: For patients originally born in a country that is currently listed as "historic only", where the original birth country now has a one-to-many relationship with the current country, how should the reported original birthplace be coded? (Example: Yugoslavia)
Assign code for Europe, NOS (ZZE) for Yugoslavia, NOS, without further information.
SEER Summary Stage 2000--Melanoma: Can Clark's level classification still used to Summary Stage melanoma? It was previously used by AJCC TNM, but was not included in the 7th edition. I see it is still listed in the CAP protocols for melanoma.
Clark's level can be used to assign in situ, localized or regional summary stage.
If there is a discrepancy between the Clark’s level and the pathologic description of extent, use the higher Summary Stage code.
First course treatment/Date 1st surgical procedure--Colon: Should the date of a polypectomy be recorded in the Date of First Surgical Procedure field when the entire tumor is not removed by polypectomy? See Discussion.
The patient underwent a polypectomy. The endoscopy report noted the "single piece polypectomy" only partially removed the polyp/mass as the remainder of the mass was more fixed to the wall. The margins were not noted on the pathology report, but were presumably positive given the endoscopy report and the subsequent low anterior resection (LAR) that proved macroscopic residual tumor. Should the date of the polypectomy be recorded in Date of First Surgical Procedure field? Or would the date of the subsequent LAR be recorded since macroscopic residual tumor was present following polypectomy?
Record the date of the polypectomy as the date of first surgical procedure. Polypectomies are surgery for the purposes of cancer registry data collection regardless of whether or not there is residual tumor after the polypectomy.
Reportability--Lung: Is a case of pulmonary metastatic leiomyoma (favored) vs. low grade leiomyosarcoma reportable, and if so, what is the primary site and histology code? See Discussion.
Patient presents with an abnormal chest x-ray. PET reveals 4.6 cm left lower lobe mass and several additional bilateral nodules measuring up to 1.6 cm. Biopsy was recommended and is positive for metastatic histologically benign smooth muscle neoplasm. ER/PR are positive. Mayo consult on biopsy agrees with histology. The differential diagnosis includes benign metastasizing leiomyoma and low grade leiomyosarcoma. Comment: If these nodules remain small and do not progressively grow would consider this metastasizing leiomyoma. Physicians state bilateral pulmonary metastatic leiomyoma (favored) vs low grade leiomyosarcoma. Tamoxifen was started. Patient has a history of uterine fibroids. Several months later, imaging reveals stable bilateral multi pulmonary nodules and left lower lobe mass but persistent. Surgery was recommended but cancelled due to insurance.
This case is not reportable based on the information provided. The histologic diagnosis is "metastatic histologically benign smooth muscle neoplasm." The physicians seem to agree with the histologic diagnosis, benign metastasizing leiomyoma (BML). The WHO classification and ICD-O-3 assign 8898/1 to "metastasizing leiomyoma." WHO states "This resembles a typical leiomyoma but it is found in the lungs of women with a history of typical uterine leiomyomas." A recent article states "Because of the hormone-sensitive characteristics of BML, treatments are based on hormonal manipulation along with either surgical or medical oophorectomy." Tamoxifen treatment is in keeping with the BML diagnosis.
Radiation Therapy--Breast: Are iodine 125 (I-125) seed implants for breast cancer coded as brachytherapy or as a localization technique similar to wire localization? See Discussion.
We are seeing many I-125 seed implants for breast cancer. Many of my associates are coding them as brachytherapy. I think they are the newest of the localization technique like wire localization but with greater accuracy. Most are done the same day as the surgery so brachytherapy does not make sense. Which is correct?
I-125 seeds could be used for brachytherapy for breast cancer or as a localization technique for nonpalpable breast tumors. If the seeds were in place a short time and removed as part of a breast surgical procedure, they were likely used for tumor localization. Radioactive seed localization (RSL) is thought to be more precise than the wire implantation technique for localizing lesions.
Surgery of Primary Site--Melanoma: Please further explain the SEER Note under Melanoma surgery codes 30-36 for these two examples. Are both examples coded 31?
1. Shave bx: +melanoma in situ, +microscopic margins Wide excision: no residual melanoma in situ
2. Shave bx: melanoma, +microscopic margin Wide excision: Melanoma, margins negative (margin status negative but distance not stated)
Revised answer: Assign surgery code 30 for both examples based on the SEER Note on the top of page 2 in the Surgery of Primary Site Codes for Skin: If it is stated to be a wide excision or reexcision, but the margins are unknown, code to 30.
