Abstract

BACKGROUND: Primary Gastrointestinal Non- Hodgkin's Lymphoma (GIL) represents 4 to 20 % of all Non-Hodgkin's Lymphoma(NHL) and gastrointestinal tract(GIT) is the most frequently involved extranodal site in NHL. It is known that the prognosis of GIL is better than that of other NHLs because of it's unique biologic behavior and anatomical location. We reviewed clinical aspects of GIL and analyzed survival data based on Ann-Arbor and Musshoff's staging system.
METHODS
Sixty six cases were analyzed by age, sex, clinical manifestation, location, histology, clinical course, and two staging systems (Ann Arbor and Musshoff's modified staging). Histologies were reviewed according to REAL classification.
RESULTS
The median age was 51.5 years. The most frequent gross finding was ulcerofungating lesion in upper GIL and mass lesion in lower GIL. Treatment results were as following : 76.9% of response rate, 59.5% of 5-year overall survival rate, and 54.8% of 5-year disease free survival rate. There was a significant difference of overall survival or disease free survival rate between group below stage IIE1 and above IIE2 according to Musshoff's staging system. There were no significant differences in survival between stage I and II, and between stage III and IV based on Ann Arbor staging system.
CONCLUSION
There might be the necessity of discriminating localized disease (IIE1) and locally advanced lesion (IIE2) to predict the prognosis of GIL through Musshoff's staging system. Larger study will be needed to confirm the role of Musshoff's staging system.
