Ultrafast papanicolaou stain modified for developing countries: efficacy and pitfalls

Area of Science:

• Cytopathology
• Diagnostic Cytology
• Histopathology Techniques

Background:

• Rapid cytologic diagnosis is crucial for patient management.
• Traditional staining methods can have lengthy turnaround times.
• Assessing specimen adequacy during procedures like fine needle aspiration cytology (FNAC) is vital.

Purpose of the Study:

• To evaluate the efficacy of the ultrafast Papanicolaou (UFP) staining technique for immediate cytologic diagnosis.
• To assess specimen adequacy during radiologically guided FNAC procedures.
• To objectively evaluate UFP stain quality and influencing factors.

Main Methods:

• Cytologic material from 347 patients over 2 years was analyzed.
• Samples included outpatient FNACs, radiologically guided FNACs, and intraoperative cytology.
• Air-dried smears were stained with UFP for immediate assessment and diagnosis.

Main Results:

• Immediate diagnosis was achieved in 85.6% of cases.
• Staining difficulties impacted diagnosis in only 2.3% of cases.
• High concordance (98%) and good/excellent morphology (75%) were observed, facilitating diagnosis.

Conclusions:

• The UFP staining technique is accurate and reliable for rapid cytology reporting.
• It significantly reduces test result turnaround time.
• UFP staining offers potential cost-effectiveness for patients and hospitals.
