Summary
This summary is machine-generated.Signet-ring cell carcinoma of the gallbladder (GBSRCA) presents differently and has a worse prognosis than gallbladder adenocarcinoma (GBAC). This aggressive gallbladder cancer subtype requires further investigation for improved patient outcomes.
Area Of Science
- Oncology
- Gastroenterology
- Pathology
Background
- The prognostic significance of signet-ring cell carcinoma in gallbladder cancer (GBC) remains under-evaluated.
- Gallbladder signet-ring cell carcinoma (GBSRCA) and gallbladder adenocarcinoma (GBAC) are distinct subtypes with potentially different clinical behaviors.
Purpose Of The Study
- To compare clinicopathological features and long-term survival between GBSRCA and GBAC.
- To determine the independent prognostic value of GBSRCA.
Main Methods
- Analysis of 6,612 gallbladder cancer patients from the Surveillance, Epidemiology, and End Results (SEER) database (2000-2021).
- Comparison of clinicopathological characteristics and survival outcomes between 147 GBSRCA and 6,465 GBAC cases.
- Propensity score matching was employed to adjust for confounding factors.
Main Results
- GBSRCA patients were younger, more frequently female, and presented with more advanced tumor stage, lymph node metastasis, and poorer differentiation.
- Patients with GBSRCA exhibited significantly worse overall survival (OS) and cancer-specific survival (CSS) compared to GBAC.
- GBSRCA was identified as an independent negative prognostic factor for OS.
Conclusions
- Gallbladder signet-ring cell carcinoma is associated with distinct clinicopathological features and a poorer prognosis than gallbladder adenocarcinoma.
- The findings highlight the aggressive nature of GBSRCA and the need for targeted therapeutic strategies.
