Does Cryofixation of Skin Specimens Affect Quality of Subsequent Formalin Fixed Paraffin Embedded H and E Histology

Squamous Cell Carcinoma Clinical Trial

Official title:
Does Cryofixation of Skin Specimens Affect Quality of Subsequent Formalin Fixed Paraffin Embedded H&E Histology

Clinical Trial Summary

This prospective study of 60 slides of basal and squamous cell carcinomas of the skin aims to determine whether:

1. The process of cryofixation prior to generating formalin fixed paraffin embedded (FFPE) H&E sections alters the histology in skin tumor specimens.

2. Which specific histologic parameters are altered between previously cryofixed versus routine FFPE sections. Histologic observations will be recorded by two dermatopathologists and two Mohs surgeons and statistically analyzed.

Clinical Trial Description

Generating formalin fixed paraffin embedded (FFPE) hematoxylin and eosin (H&E) stained permanent sections from previously cryofixed tissue is a common practice used to confirm diagnosis of frozen section histology. In dermatology, this practice can be used to examine Mohs layers and its debulk as well as routine nonmelanoma skin cancer (NMSC) biopsies after initial histologic diagnosis with frozen sections. Even though freezing tissue can introduce histologic artifacts, there have been no studies documenting whether this occurs specifically in cryofixed tissues that are subsequently thawed for permanent FFPE H&E histology. The purpose of our study is to determine whether the freeze-thaw process used to generate permanent sections after cryofixation introduces significantly detectable histologic differences compared to permanent sections that were not previously cryofixed. Thirty debulk specimens of basal cell and squamous cell carcinomas will be prospectively collected. Each specimen will be split so that half is processed as cryofixed permanents and the other half as noncryofixed permanents. The investigator will show each slide in random order to a group of four blinded participants (two dermatopathologists and two Mohs surgeons). Each participant must first rate the overall quality of histology. Then, each participant will rate each slide on the quality of cellular morphology, nuclear morphology, color and contrast of stains, intactness of specimen, and other miscellaneous artifacts. These data will then be analyzed for statistical significance. ;
