FIGURE 1.

Kaplan–Meier overall survival stratified by treatment strategies and prognostic factors. (A) Median OS for patients stratified by receiving only LT versus only ST, versus LT followed by ST (patients receiving only best supportive care were excluded). (B) Median OS for patients stratified by receiving only surgery versus surgery + NSLRI (patients that did not receive surgery were excluded). (C) Median OS for patients stratified by remnant tumor burden and sum of diameters >5 cm was considered “high tumor burden,” while those ≤5 cm was considered “low tumor burden.” LT = locoregional treatment, NSLRI =  non-surgical locoregional interventions, OS = overall survival, ST = systemic therapy.
