Borrmann type IV: an independent prognostic factor for survival in gastric cancer.
BACKGROUND
Borrmann type IV gastric cancer has a poorer prognosis than other gastric carcinomas. This study compared the clinicopathological features of Borrmann type IV gastric cancer with those of other types of cancer and examined the significance of a Borrmann type IV carcinoma as a prognostic factor after gastrectomy.


METHODS
The clinicopathological features, tumor-node-metastasis (TNM) stage, and survival rates of 4,191 advanced gastric cancer patients, who had undergone a gastrectomy at the Samsung Medical Center between 1995 and 2005, were reviewed.


RESULTS
Borrmann type IV gastric cancer was found to be associated with more advanced and unfavorable clinicopathological features at diagnosis than the other cancers. The 5-year survival rate of the patients with Borrmann type IV cancer was 27.6%. In contrast, the 5-year survival rate of patients with the other types of cancer was 61.2%. The 5-year survival rate for each stage of Borrmann type IV gastric cancer and the other type gastric cancer was 61.0% and 88.8% for stage Ib (P < 0.001), 49.8% and 76.1% for stage II (P < 0.001), 36.4% and 55.1% for stage IIIa (P < 0.001), 15.2% and 38.5% for stage IIIb (P = 0.001), and 10.2% and 20.1% for stage IV (P = 0.008), respectively. Multivariate analyses revealed a Borrmann type IV carcinoma, the surgical extent, curability, tumor stage, including T, N, and M status, and adjuvant therapy to be independent prognostic factors for survival.


CONCLUSIONS
A Borrmann type IV carcinoma has unique clinicopathological features compared with other types of gastric carcinomas and is an important independent prognostic factor.
