Used with permission of the American College of Surgeons, Chicago, Illinois.\n\n**Note 2:** 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**Note 3:** Noninvasive papillary transitional carcinoma: Pathologists use many different descriptive terms for noninvasive papillary transitional cell carcinoma. Frequently, the pathology report does not contain a definite statement of non-invasion; however, non-invasion can be inferred from the microscopic description. \n\n A. Definite statements of non-invasion for papillary transitional cell carcinomas (Ta) 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 non-invasion for papillary transitional cell carcinomas 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 (non-invasion 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 \n\n**Note 4:** 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 non-invasion 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 (IS). \n* If the tumor has penetrated the basement membrane to invade the lamina propria: then it is invasive and coded to 1 for localized. 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\" (IS).\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 5:** Code 2 for regional 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.",
