PI prevention in advanced cancer requires individualized assessment that integrates PI risk, skin and tissue status, pressure exposure, nutritional condition, symptom burden, prognosis, patient preferences, and goals of care. Oncology-specific evidence is available for selected risk factors and assessment tools, whereas many preventive interventions are supported primarily by evidence from broader high-risk populations. Pressure-redistribution support surfaces provide a comparatively low-burden foundation for prevention; repositioning frequency should be individualized; preventive silicone foam dressings may be used selectively at high-risk sites; and nutritional and symptom-management interventions should follow oncology and palliative-care indications while supporting pressure-relief goals. As patients move from ongoing palliative care toward the actively dying phase, the relative priority assigned to immediate relief of comfort, pain, and dyspnea, sleep, dignity, and patient/family preferences should increase, and burdensome preventive interventions may appropriately be reduced. The comfort-prioritized, risk-stratified framework presented in this review is an author-developed conceptual approach that integrates evidence certainty, clinical risk, intervention burden, prognosis, and goal-concordant care across the advanced-cancer trajectory.

Figure 1: Comfort-prioritized, risk-stratified decision framework for pressure-injury prevention in patients with advanced cancer. The framework integrates phase of care, prognosis, goals and preferences, PI risk, pressure exposure, skin condition, nutrition, symptoms, cognition, and tolerance of preventive interventions to guide individualized prevention or a comfort-focused low-burden approach, with ongoing reassessment across the disease trajectory.

Figure 2: Conceptual continuum of pressure-injury prevention across the advanced-cancer trajectory. The relative intensity of burdensome active prevention is progressively individualized as disease advances and tolerance declines, while the priority assigned to immediate comfort and symptom relief increases; low-burden passive strategies may be maintained when comfortable and feasible.
