mitotic rate

mi·tot·ic rate

the proportion of cells in a tissue that are undergoing mitosis, expressed as a mitotic index or, roughly, as the number of cells in mitosis in each microscopic high-power field in tissue sections.

The researchers found that in the Leicester cohort, CTA was an independent prognostic factor after adjusting for Breslow thickness, age, sex, ulcer, mitotic rate, and microsatellites (hazard ratio [HR], 1.87).
Tumours categorised as low grade have Ki-67 index of less than 3% and a mitotic rate 20/10 HPF.
(1, 8) However, a subgroup of PMDM showing marked pleomorphism, decreased cell cohesion, atypical mitotic figures, and high mitotic rate (>5 mitosis/10 high-power fields) seems to have a highly aggressive clinical course.
Most cases demonstrated minimal atypia and low mitotic rate (0-1/10 high power field (hpf)), consistent with low-grade features.
Otorhinolaryngologic examination showed a 3.8 cm x 2.5 cm growth right pyriform sinus (PFS), biopsy from which revealed pleomorphic spindle cell tumor with large hyperchromatic nuclei, prominent nucleoli with frequent mitosis with a mitotic rate of 4 per high-power-field arranged in intersecting fascicles.
The tumor was assigned a Breslow depth of 6.5mm and a mitotic rate of 5/mm2.
* Dermal mitotic rate is no longer used in staging T1 tumors, although it's still supposed to be included in pathology reports.
* Dermal mitotic rate is no longer used in staging Tl tumors, although it's still supposed to be included in pathology reports.
found through multivariate analysis that mitotic rate [greater than or equal to] 5, tumor size [greater than or equal to] 10 cm, and primary tumor location were independent factors for recurrence [21].
After Breslow thickness, both mitotic rate and ulceration reporting are important for the surgical oncologist in treatment planning.
Minimal pleomorphism and a mitotic rate of <2 mitotic figures/50 HPFs are identified.
In general, prognosis of GIST depends upon the size of the tumor and to the mitotic rate: tumors > 10 cm or with a mitotic rate of >5 per 50 HPF having higher risk of recurrence, metastatic spread, and a poorer prognosis.
