Analysis of a two-marker immunohistochemistry panel (TTF-1 and p40) for distinguishing lung adenocarcinoma from squamous cell carcinoma on destained direct cytologic smears

Puntos clave

• TTF-1 and p40 markers effectively distinguish adenocarcinoma from squamous cell carcinoma on cytologic smears.
• The analysis found a strong correlation rate of over 85% for accurate diagnoses based on these two markers.
• Studies focused on direct cytologic smears, highlighting the necessity for reliable and efficient diagnostic methods in lung cancers.
• This approach may enable faster and more accurate diagnosis for lung cancer types, improving patient outcomes significantly.
