| description | Introduction: Conventional formalin-fixed, paraffin-embedded
tissue provides superior cellular morphology and long-term
storage. Problems with formalin fixation comprise delay of fixation
and variations in the duration of fixation. Microwave assisted
tissue fixation removes the use of noxious and potentially toxic
formalin that decreases the turnaround time and creates a
personnel friendly workflow.
Material and Methods: The present study was conducted over a
period of two years. One hundred and forty paired tissue sections
were taken including both neoplastic and non-neoplastic tissues.
One of the paired tissues was fixed in formalin and the other
was fixed by using microwave irradiation in phosphate buffered
saline. Both were then processed by conventional method. Each
slide was examined and rated for the adequacy of fixation by
two pathologists in a blinded fashion using 7 parameters: Cellular
outline, cytoplasmic detail, nuclear detail, erythrocyte integrity,
lymphocyte appearance, overall morphology and overall
staining.
Results: Statistical analysis showed that sections obtained from
microwave fixed tissues were comparable to that of routinely fixed
tissue. The p-values of all parameters were not significant except
for the overall morphology for which p-value was significant
owing to loss of tissue in some cases.
Conclusion: Microwave irradiation substantially shortened the
time from specimen reception to diagnosis (turnaround time) and
allowed same-day tissue processing and diagnosis of specimens
without compromising the overall quality of the histologic
section. |
