XXXX : a pathologic and clinical study of 46 cases.

@entity1 @entity6090 @entity5 @entity189 @entity2802 @entity420
@entity189 is a rare @entity5 that has not been well studied. To determine the pathologic and clinical features of this disease, we retrospectively evaluated 46 cases from our surgical pathology files. The @entity1 included 16 @entity1 and 30 @entity1 , with a mean age of 53.4 years (range, 28-82 years). Forty @entity1 had undergone cystectomy, and the remaining 6 had undergone transurethral bladder biopsy. @entity5 were located at the dome (n = 44); only 2 were located at both the dome and anterior wall. All @entity5 consisted of @entity420 , including mucinous (n = 36), enteric (n = 7), not otherwise specified (n = 2), and signet ring cell (n = 1) types. Focal areas of signet ring cell features were present in 23 cases, but @entity189 in situ was not identified in any cases. The @entity5 invaded the muscularis propria (n = 8), perivesical adipose tissue (n = 27), and abdominal wall (n = 3). Twenty-five @entity1 had died of @entity5 at a mean of 32 months (range, 12-74 months), and 21 @entity1 were alive at a mean of 65 months (range, 7-230 months). The median @entity5 -specific survival time of @entity6090 @entity1 was 45 months, which was significantly longer than that of bladder @entity189 @entity1 with similar-stage disease (P = .047). @entity1 ' @entity5 -specific survival was associated with @entity5 stage according to the Sheldon, Mayo, and @entity2802 staging systems. In conclusion, @entity189 are predominantly composed of invasive @entity420 , which commonly demonstrate mucinous features. @entity5 present at advanced stages but are still associated with a better survival rate than bladder @entity189 .
