MP/H Rules/Multiple primaries--Bladder: How many primaries are to be abstracted and how are the histologies coded when a bladder resection demonstrates tumor with invasive small cell neuroendocrine carcinoma [8041/3], high grade papillary urothelial carcinoma in situ [8130/2], adenocarcinoma in situ [8140/2], and multifocal flat urothelial carcinoma in situ? See Discussion.
Surgery of Primary Site/Surgical Procedure of Other Sites--Endometrium: How are these fields coded for an endometrial primary when the patient undergoes a radical tumor cytoreduction including modified radical hysterectomy, BSO, omentectomy, resection of intra-abdominal and intrapelvic implants, and partial cystectomy? See discussion.
Date Multiple Tumors--Prostate: For a prostate biopsy done 10/20/08, both lobes involved with tumor, unknown how many tumors, what would be coded in date of multiple tumors?
Date of Diagnosis--Bladder: Should the date of diagnosis be based on the 1/7/04 urine cytology with low grade transitional cell carcinoma or the subsequent 1/27/04 pathology findings of papillary transitional cell carcinoma?
Date Therapy Initiated: What date should be entered in Date Therapy Initiated when treatment follows a surgical procedure that is not coded under Surgery of Primary Site? See discussion.
Multiplicity Counter--Breast: How should the multiplicity counter be coded for a 3.8 cm infiltrating duct carcinoma with two "satellite nodules" measuring 5 mm and 7mm that are not described as either metastases or multiple foci?
