Experience of 463 cases of gastric cancer from a single surgical center

Ann Ital Chir. 2015:86:513-7.

Abstract

Aim: To evaluate clinical and histopathological changes of gastric cancer (GC) in the last fifteen years and analyze factors influencing overall survival.

Material of study: We have retrospectively categorized patients submitted to surgery for GC from January 1996 to December 2010. The analysis focused on two periods: 1996-2003 (period 1) and 2004-2010 (period 2).

Results: There was an increase in age distribution of GC in period 2 (p=0.012). Significant increase of whole GC was observed in period 2 (p=0.01). Slight but significant changes in TNM stage were found: in group 2 there was a decrease in the rate of early GC and in advanced depth of tumor invasion; increase of lymph nodes involvement was also demonstrated. Overall survival (OS) had not changed from the first to the second period. There was a significant difference in OS calculated for Lauren histotype: from ten months to surgery, patients with diffuse histotype showed worse prognosis.

Discussion: The most important findings were an increase in lymph node involvement and a decrease in depth of tumor invasion, an higher percentage of whole type and a decrease in palliative surgery. Overall-survival hasn't change in the last fifteen years. These results confirms the importance of extent of lymph node dissection in the standard surgical approach of GC, the tumor stage and Lauren histotypes as the main prognostic factors in GC.

Conclusion: This work confirms the dismal prognosis of GC and the need to increase diagnosis of early gastric cancer.

Key words: Gastric cancer, Lauren histotype, Overall survivall.

Lo scopo di questo studio è stato analizzare i cambiamenti clinici ed istopatologici del cancro gastrico negli ultimi quindici anni ed analizzare i fattori che influenzano la sopravvivenza globale. Abbiamo retrospettivamente analizzato i pazienti sottoposti a chirurgia per il cancro gastrico da gennaio 1996 a dicembre 2010. L’analisi si è focalizzata su due periodi: 1996-2003 (periodo 1) e 2004-2010 (periodo 2). Abbiamo riscontrato un incremento dell’età di distribuzione del cancro gastrico nel secondo periodo (p=0.012). Sono emersi lievi ma significativi cambiamenti nello stadio della neoplasia (Sistema di stadiazione TNM - 7 th edizione). Non sono stati rilevati cambiamenti nella sopravvivenza globale negli ultimi quindici anni; mentre è stata riscontrata una prognosi peggiore per il tipo diffuso secondo Lauren. I risultati confermano l’importanza di una linfoadenectomia estesa nel trattamento standard del cancro gastrico. Questo lavoro conferma la pessima prognosi dei pazienti affetti da cancro gastrico e la necessità di incrementare la diagnosi di questo tumore ad uno stadio precoce.
