"notes" : "**Note 1**: The two main types of bladder cancer are the flat (sessile) variety and the papillary type. The flat (sessile) variety is called in situ when tumor has not penetrated the basement membrane. Papillary tumor that has not penetrated the basement membrane is called noninvasive.\n\n* A. Definite statements of noninvasion for papillary transitional cell carcinomas (code 010) include: \n Noninfiltrating\n Noninvasive\n No evidence of invasion\n No extension into lamina propria\n No stromal invasion\n No extension into underlying supporting tissue\n Negative lamina propria and superficial muscle\n Negative muscle and (subepithelial) connective tissue\n No infiltrative behavior/component\n* B. Inferred descriptions of noninvasion for papillary transitional cell carcinomas (code 030) include: \n No involvement of muscularis propria and no mention of subepithelium/submucosa\n No statement of invasion (microscopic description present)\n (Underlying) Tissue insufficient to judge depth of invasion\n No invasion of bladder wall\n No involvement of muscularis propria\n Benign deeper tissue\n Microscopic description problematic (noninvasion versus superficial invasion)\n Frond surfaced by transitional cell\n No mural infiltration\n No evidence of invasion (no sampled stroma)\n Confined to mucosa (see also Note 3 if tumor is not described as papillary)\n\n**Note 3**: Noninvasive (in situ) flat transitional cell carcinoma: Careful attention must be given to the use of the term \"confined to mucosa\" for flat bladder carcinomas. Historically, carcinomas described as \"confined to mucosa\" were coded as localized. However, pathologists use this designation for noninvasion as well. Pathologists also vary in their use of the terms \"invasion of mucosa, grade 1\" and \"invasion of mucosa, grade 2\" to distinguish between noninvasive and invasive carcinomas. In order to accurately code tumors described as \"confined to mucosa\", abstractors should determine:\n \n* If the tumor is confined to the epithelium: then it is noninvasive (code 060). \n* If the tumor has penetrated the basement membrane to invade the lamina propria: then it is invasive (code 155). The lamina propria and submucosa tend to merge when there is no muscularis mucosa, so these terms may be used interchangeably, along with stroma and subepithelial connective tissue. \n* If the distinction between involvement of the epithelium and lamina propria cannot be made, then the tumor should be coded as \"confined to mucosa, NOS\" (code 100).\n Statements meaning confined to mucosa, NOS for flat transitional cell carcinomas include:\n * Confined to mucosal surface\n * Limited to mucosa, no invasion of submucosa and muscularis\n * No infiltration/invasion of fibromuscular and muscular stroma\n * Superficial, NOS\n\n**Note 4**: In case of multifocal noninvasive Ta and Tis tumors, use code 060 or 100 in preference to 010 or 030.\n\n**Note 5**: Use code 230 if the only description of extension is through full thickness of bladder wall, and there is no clear statement as to whether or not the cancer has extended into fat. If there is documentation that tumor has breached the wall, including invasion into fat or beyond, use code 411 or higher.\n\n**Note 6**: An associated in situ component of tumor extending into the prostatic ducts, prostatic glands, or ureter without invasion is disregarded in staging classification. Use the code that best describes depth of bladder wall invasion. \n\n**Note 7**: Direct invasion of the distal ureter is classified by the depth of greatest invasion in the bladder or ureter for AJCC staging. Use codes 165, 215, 235, and 245 for extension from bladder directly into distal ureter. The distal ureter is defined as below the iliac vessel, within the pelvic brim. \n\n**Note 8**: Extension from bladder into subepithelial tissue of prostatic urethra should be coded 160 and not code 600.\n\n**Note 9**: If CS Extension code is 010-060, Behavior ICD-O-3 must be coded as 2. If CS Extension code is 100, Behavior ICD-O-3 may be coded as 2 or 3. If CS Extension code is 155 or greater, Behavior ICD-O-3 must be coded as 3.",
