Background:

The biology of some hematological diseases varies among different populations. No previous studies have evaluated the clinical behavior of mantle cell lymphoma (MCL) in México.

Objective and Methods:

This is a retrospective review of MCL cases seen in Mexico from January 2003 to June 2020. A total of 12 cases were identified.

Results:

There were nine males and three females; median age was 56 years. Eight patients had a high MCL international prognostic index score, one was intermediate, and three were low. Five patients had circulating malignant monoclonal cells. Initial treatment included rituximab, cyclophosphamide, daunorubicin, vincristine, and prednisone (R-CHOP) and CHOP. Subsequent treatment included hematopoietic stem cell transplantation in five patients; two were given maintenance therapy. Splenectomy was done in four patients. Median overall survival (OS) for all the patients has not been reached and exceeds 162 mos: OS at 162 mos was 56%. Achieving a complete remission (CR) after the first treatment was a significant prognostic factor, with a median OS exceeding 141 mos in patients achieving CR, and 16 mos among those not achieving CR (p = 0.0006).

Conclusion:

Some of MCL patients in Mexico have an indolent clinical course, particularly patients who achieve a CR to initial treatment and who undergo splenectomy.
