title: [Bone marrow biopsy in myeloproliferative syndromes: prognostic value of cellular quantification].
abstract: The proportion of granulocytes, erythroblasts, immature cells and megakaryocytes was evaluated when revising the bone-marrow biopsy specimens of 36 patients with myeloproliferative syndromes. These proportions were compared between themselves, a so-called Z value being thus attained; such value resulted from summing the proportion of granulocytes, megakaryocytes and immature cells and subtracting the proportion of erythroblasts. According to its value, above or below the mean, the Z figure correlates with the survival, the difference between both groups appearing as statistically significant (p = 0.02).
