Using a database comprising 13,266 cytogenetically abnormal neoplasms, the geographic heterogeneity of neoplasia-associated chromosomal abnormalities was investigated by comparing the frequencies of characteristic aberrations in consecutive series of patients with the same diagnosis. Significant frequency differences between geographic areas were found for the aberrations +8, i(17q), +19, and an additional Ph1 chromosome in chronic myeloid leukemia (CML); -5, 5q-, and +8 in acute nonlymphocytic leukemia (ANLL); t(8;21) in ANLL-M2; t(15;17) in ANLL-M3; 5q- and -7 in myelodysplastic syndromes (MDS); t(9;22) and +21 in acute lymphocytic leukemia (ALL); t(14;18) in follicular lymphoma; -8 and -22/22q- in meningioma; and structural abnormalities of 12q in pleomorphic adenoma of the salivary glands (PAS). No geographic incidence variation was detected for -7 and +21 in ANLL; +8 in MDS; 6q- and +8 in ALL; +12 in chronic lymphocytic leukemia; 6q- in non-Hodgkin's lymphoma (NHL); t(8;14) in Burkitt's lymphoma; t(11;22) in Ewing's sarcoma; i(12p) in germ cell tumors; 1p- in neuroblastoma; structural abnormalities of 3q, 8q, and 9p in PAS; or 3p- in renal cell carcinoma. Intraregional frequency similarities between cytogenetically identical abnormalities in related tumor types were also analyzed. No significant correlations were found regarding the incidence of 5q- in ANLL and MDS, 6q- in ALL and NHL, -7 in ANLL and MDS, +8 in ANLL and CML, +8 in ANLL and MDS, +8 in ALL and ANLL, or +21 in ALL and ANLL. The findings indicate that some geographic heterogeneity of tumor-associated aberrations exists both in hematologic neoplasms and in solid tumors.(ABSTRACT TRUNCATED AT 250 WORDS)

Intracranial meningiomas are generally slow-growing neoplasms. Symptoms depend on their critical intracranial location. The authors describe a case of rapidly enlarging meningioma that became symptomatic as a result of invasion by leukemic cells at the time of a blastic crisis in the context of chronic myeloid leukemia. Infiltration of an intracranial meningioma by cells from extracranial malignant neoplasms is a rare event. Even though central nervous system (CNS) or meningeal involvement is common in some hematologic malignancies, this is, to the best of our knowledge, the first report of invasion of an intracranial meningioma by leukemic cells.

The treatment and prognosis of chronic myeloid leukemia have dramatically changed since the introduction of tyrosine kinase inhibitors, but although several clinical trials have examined their safety with respect to heart function, no data are yet available about the use of these drugs in patients with Brugada syndrome. We report a case of Brugada syndrome diagnosed during tyrosine kinase inhibitor therapy in a 69-year-old Caucasian male with meningioma and chronic myeloid leukemia. This case report highlights the importance of an integrated approach among hematologists and cardiologists to ensure appropriate treatment with tyrosine kinase inhibitors in patients affected by chronic myeloid leukemia who also suffer from Brugada syndrome.
