Abstract
AIM
To analyze the treatment outcome of radiotherapy for localized primary ocular adnexal mucosa-associated lymphoid tissue lymphoma (POAML) and evaluate the prognostic effect of the American Joint Committee on Cancer (AJCC) tumor-node-metastasis (TNM) clinical staging system for POAML.
PATIENTS AND METHODS
Seventy-three patients with Ann Arbor stage IE POAML who were treated with radiotherapy alone were analyzed. T-Factor based on the AJCC staging system was T1 in 28, T2 in 33 and T3 in 12 patients.
RESULTS
Out of nine patients with relapse, six had distant and three had contralateral ocular adnexal relapse. One patient died of lymphoma progression. The 5-year local control and progression-free survival (PFS) rates were 100% and 81.5%, respectively. T-Factor was not significantly associated with PFS.
CONCLUSION
Radiotherapy achieved excellent local control and survival rates for stage IE POAML. The AJCC TNM clinical staging system was not significantly predictive for PFS of stage IE POAML.
