The full value of classical cytomorphology can be boosted by new technologies, including improvements in cell block techniques (2-4) and better microbiopsy needles.
2) It seems likely that improvements in microbiopsy needle design will widely boost the value of cytology and could allow cytology to reemerge as the primary diagnostic tool for breast masses.
The sensitivity is impressive from a sample of only about 2,000 cells, a microbiopsy that's less invasive for patients," he said.
The volume concludes with a look at new microbiopsy system that enables rapid preparation of tissue for high-pressure freezing.
And the development, on embryos, of microbiopsy techniques for DNA analysis would provide a better understanding of such hereditary diseases as sickle cell anemia, Down's syndrome, and Tay-Sachs disease, and might ultimately result in "gene therapies" that would erase these conditions--by re-sequencing the nucleotides (the building blocks of DNA), for example.
9) Although concurrent fine needle-sized pCLE probes theoretically offer the potential for submucosal staging, there would not seem to be much of an advantage of using needle-based CLE over other minimally invasive microbiopsy techniques.
44) With improvements in the speed and efficiency of recovery of FNA microbiopsy fragments for paraffin embedding and sectioning and with improvements in microbiopsy needle design, there would not seem to be much of an advantage in using the new needle-based pCLE system for diagnosing solid organs.
