[Analysis of the non-Hodgkin lymphoma's clinic and blood marrow cytogenetics].
ABSTRACT To analyze the relationship among cytogenetics, hematopathology, morphology, clinic tumor index and prognosis of the non-Hodgkin lymphoma(NHL) patients.
Cytogenetics analysis of bone marrow cells was performed by direct method and 24 h culture method in 20 cases of NHL. Serous P53 protein was detected in all patients.
Out of the twenty NHL patients, eight had bone marrow infiltration, and nine were found with abnormal karyotype: three were chromosome number abnormalities, one was t(14,18)(q32;q21), one was 14q+, two were t(8;14)(q24;q32), two were t(8;14)(q24;q32) with additional changes of chromosome. The serous P53 protein of patients with abnormal karyotype was significantly higher than that with normal karyotype.
t(8;14) (q24;q32) is the most classic translocation in NHL, The patients with this karyotype have worse prognosis. The increase of mutant serous P53 relates to abnormal karyotype, and the patients with high mutant P53 level in serum also have worse prognosis.
