Uncommon Presentation of Primary Bladder Signet Ring Cell Carcinoma With Peritoneal Carcinomatosis: A Rare Case Report.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Primary signet ring cell carcinoma (SRCC) of the bladder is an exceptionally rare and aggressive malignancy, accounting for only 0.12%-0.6% of all bladder cancers. This case report describes a 54-year-old female who presented with urinary incontinence and abdominal pain, initially misdiagnosed as a urinary tract infection. Imaging revealed suspicious bladder findings, and subsequent cystoscopy with transurethral resection identified SRCC, later confirmed by immunohistochemistry (PD-L1 positive, CDX-2/ER negative). Despite peritoneal carcinomatosis, the patient responded to cisplatin/gemcitabine chemotherapy and immunotherapy, demonstrating tumor shrinkage on follow-up imaging. This case highlights the diagnostic challenges of SRCC due to its nonspecific symptoms and potential histological overlap with other metastatic gastrointestinal tumors. Early recognition and a multidisciplinary approach are critical for improving patient outcomes.
