[Sensitivity test for anti-tumor agents-3. MTT assay and its clinical effect]

Area of Science:

• Oncology
• Cell Biology
• Clinical Pharmacology

Background:

• The MTT assay is a standard method for evaluating the efficacy of anti-tumor agents.
• Assessing the clinical usefulness of the MTT assay is crucial for personalized cancer therapy.
• Accurate prediction of drug sensitivity and resistance impacts patient treatment strategies.

Purpose of the Study:

• To evaluate the clinical usefulness of the MTT assay as a sensitivity test for anti-tumor agents.
• To determine the predictive accuracy of the MTT assay for both drug sensitivity and resistance.
• To assess the utility of the MTT assay in guiding the selection of effective anti-cancer drugs.

Main Methods:

• The MTT assay was performed on cell suspensions from 15 surgical specimens.
• Papanicolaou (Pap) smears were used to confirm malignant cells and assess tumor cell density (≥50%) in chamber slides for MTT assay validity.
• Cell cultures in chamber slides were used for strict assessment of cancer cells.

Main Results:

• The MTT assay demonstrated a 64.2% predictive accuracy for anti-tumor agent sensitivity.
• The assay achieved 100% predictive accuracy for drug resistance.
• Overall predictability for treatment effectiveness was 66.7%.

Conclusions:

• The MTT assay is a valuable tool for determining the sensitivity of anti-tumor agents.
• Confirmation of cancer cells via chamber slides ensures the reliability of MTT assay results.
• The MTT assay is clinically useful for identifying effective drugs and eliminating ineffective ones, optimizing cancer treatment decisions.
