Brief Summary:
There has been much controversy surrounding the biologic behavior and prognosis of esophageal signet ring cell (SRCs) containing carcinomas. To clarify the biologic behavior of SRCs, the investigators compared the clinicopathologic features and prognosis of SRCs with other adenocarcinomas (ADC) of the esophagus and gastroesophageal junction (GEJ).

Condition or disease
Adenocarcinoma Esophageal Cancer

Detailed Description:

Adenocarcinoma (ADC) of the esophagus and gastroesophageal junction (GEJ) is an aggressive neoplasm and has a poor prognosis. Surgical based treatment has been the treatment of choice for localized esophageal adenocarcinoma.

Signet-ring cell carcinoma is a unique histologic subtype of adenocarcinoma characterized by abundant intracellular mucin accumulation and a compressed nucleus displaced toward one extremity of the cell (the so-called signet-ring cell (SRC)). According to the World Health Organisation (WHO), a true signet-ring cell carcinoma (SRCca) is defined as an adenocarcinoma in which the predominant component (more than 50% of the tumor) consists of isolated or small groups of SRC in the stroma. If the tumor contains less than 50% of those cells, it is generally considered as an adenocarcinoma (ADC).

Sampling Method:   Non-Probability Sample
Study Population
From our prospectively built database we retrieved all adenocarcinoma from 1990 till 2009 who underwent primary surgery with R0 resection. Seven hundred seventy-nine patients were included for further analysis. Pathology reports mentioning signet ring cells (n = 82) were reviewed by our pathologist and, after confirmation, tumors were classified into two groups according to WHO criteria (>50% SRC or <50% SRC). The remaining 697 ADC patients served as control group.
Criteria

Inclusion Criteria:

- Adenocarcinoma R0 resection Primary surgery

Exclusion Criteria:

- Other histology R1 or R2 resection Neoadjuvant therapy
