Place resistance in time
Define the exposure and how progression is documented. Samples taken before treatment, during response and at progression may answer different questions. An alteration found at the end does not prove that it caused resistance or establish when it appeared.
Consider genetics and cell state
Experimental research described cell subpopulations with reversible drug tolerance associated with chromatin. This finding opens a research path beyond permanent mutations; the relevance of that mechanism in a clinical setting needs its own evidence.
Examine paired data and hypotheses
Look for samples from the same person, detection methods, alteration frequency and functional validation. Public databases help explore co-occurring alterations, but sample differences and prior treatments may confound associations. Proposed treatment combinations require specific efficacy and safety evaluation.
Interpretation limits
Progression alone does not reveal the molecular mechanism responsible.
A mechanism found in cell culture does not identify an individual treatment option.
