Background:
The prognosis for patients with colorectal cancer shows variation. The characteristics of colorectal cancer patients with signet-ring cell carcinoma (SRCC) are still not clear.
Materials And Methods:
A retrospective comparison was made of the data of signet-ring cell colorectal carcinoma patients operated on between 2009 and 2018 in respect of clinicopathological and operative results, morbidity, mortality, and long-term survival.
Results:
The study included a total of 34 patients comprising 26 (76%) males and 8 (24%) females with a mean age of 58 ± 11.7 years. Incidence of SRCC was determined as 1.8%. Lymphovascular invasion was determined in 22 (64%) patients. Tumors were determined as stage T2 in 8 (32%) patients, stage T3 in 9 (36%), and stage T4 in 8 (32%). According to the TNM classification, 5 (14.7%) patients were diagnosed with stage 1, 7 (20.6%) with stage 2, 15 (44.1%) with stage 3, and 7 (20.6%) with stage 4. The mean follow-up period was 40.6 ± 30.4 months, and mean disease-free follow-up was determined as 33.1 ± 36.1 months. Fifteen (44.1%) patients died because of the disease.
Conclusion:
Although SRCC is a poor prognostic factor, it should be kept in mind when determining adjuvant therapies and prognosis of patients determined with advanced-stage SRCC.
