Summary
Pathologic splenic rupture is a rare but serious complication of hematologic malignancies. Risk factors include male sex, adulthood, severe splenomegaly, and chemotherapy, in addition to splenic infiltration.
Area of Science:
- Hematology
- Oncology
- Pathology
Background:
- Pathologic splenic rupture is an uncommon event, particularly in the context of hematologic malignancies.
- This study examines risk factors and characteristics of splenic rupture in patients with blood cancers.
Observation:
- Two cases are presented: one with non-Hodgkin's lymphoma and another with chronic lymphocytic leukemia (CLL).
- A literature review identified 136 cases of splenic rupture since 1861, with significant percentages in acute leukemias (34%) and non-Hodgkin's lymphomas (34%).
Findings:
- The male-to-female ratio for splenic rupture is 3:1, with variations based on specific hematologic diseases.
- Rupture predominantly occurs in adults with moderately to severely enlarged spleens.
- Key risk factors identified include splenic infiltration, infarcts, coagulation disorders, male sex, adulthood, severe splenomegaly, and cytoreductive chemotherapy.
Implications:
- Understanding these risk factors can aid in the early identification and management of patients with hematologic malignancies at risk for splenic rupture.
- Further research into the pathophysiology and optimal treatment strategies (operative vs. conservative) for splenic rupture in this population is warranted.
