Primary lymphoma of the colon.

BACKGROUND

primary colorectal lymphoma is a very rare disease, representing less than 0.5 % of all primary colorectal neoplasms. The gastrointestinal tract is the most frequently involved site of all extranodal lymphomas, the most common type of that is non-Hodgkin s lymphoma. Early diagnosis is often difficult because of unspecific symptoms. Therapeutic approaches have classically included radical resection, chemotherapy and radiotherapy.

MATERIALS AND

METHODS

we present our experience in the management of primary colorectal lymphomas over a 17-year period (1994-20011).

RESULTS

in this period 7 cases of primary colorectal lymphoma were diagnosed in our institution. Abdominal pain and change in bowel habit were the most frequent symptoms. Five patients underwent emergency surgery because of bleeding or bowel obstruction. All primary intestinal lymphomas studied were of the Bcell phenotype. Patients were followed up for a median of 59 months (range 1-180). Three of them are alive with no evidence of recurrence.

CONCLUSION

combination treatment with chemotherapy and surgery can obtain good remission rate. Surgery can resolve complications such bleeding or intestinal perforation that are implicated in lymphoma mortality.
