I think you are wrong here....If we already know 166th Patient OS data then median Overall survival (mOS often referred) data will not change even if the remaining patients cured (live another 10-20 years). But mean Overall survival will change as it is the average OS data of 331 patients. Median is different from mean. Median OS data will be when 166 patients in trail died. It (mOS) can get worse with remaining patients low OS data but not better.
