Palliative Performance Scale and Prognosis in Advanced Cancer

Prognostic Implications and Management

The National Comprehensive Cancer Network recommends that patients with a Palliative Performance Scale (PPS) score of 50% or less (equivalent to Karnofsky Performance Status (KPS) <60%) should receive palliative/best supportive care only, without systemic therapy, due to severely compromised functional status and limited survival 1
The American Society of Clinical Oncology supports the use of PPS scores to guide treatment decisions, with PPS 50% correlating with KPS 50%, indicating a poor prognosis and limited benefit from systemic therapy 2
The Palliative Prognostic Score (PaP) incorporates KPS 50% with additional factors, including dyspnea presence (+1 point) 3, anorexia presence (+1.5 points) 3, leukocytosis (0-1.5 points) 2, and lymphocytopenia (0-2.5 points) 2, to predict 30-day survival probability 2
The European Association for Palliative Care emphasizes the importance of patient-centered, dialogic approaches to prognostication, and recommends that prognostic tools should not impose additional patient burden 3, 4
The National Comprehensive Cancer Network guidelines suggest that patients with PPS ≤50% should initiate goals-of-care discussions immediately, and receive aggressive symptom management, coping support, and advance care planning 5, 6

The American Society of Clinical Oncology recommends that patients with advanced cancer receive core palliative care interventions, including aggressive symptom management, coping support, and advance care planning, to improve quality of life and reduce suffering 5, 6
The European Association for Palliative Care emphasizes the importance of continuing multidimensional palliative care regardless of time limits, and communicating prognosis only when requested and in culturally appropriate ways 4

The Journal of Clinical Oncology suggests that laboratory tests, including complete blood count and C-reactive protein, may be useful in refining 30-day survival probability in patients with PPS 40-50% 2

The Palliative Performance Scale (PPS) is a validated tool that assesses patient functional status across five domains and provides valuable prognostic information to guide palliative care interventions, as recommended by the World Journal of Emergency Surgery 7

The PPS can be used as a care planning tool to determine the appropriate level of care based on functional status, with the American College of Surgeons suggesting its use in clinical practice 7
The PPS score can be used to guide discussions about goals of care and end-of-life planning, with lower scores (10-30%) triggering discussions about hospice care, as suggested by the National Comprehensive Cancer Network 8

The PPS can be used alongside other prognostic tools like the Palliative Prognostic Score (PaP) to provide a more comprehensive assessment of patient prognosis, as recommended by the Journal of Clinical Oncology 9

The National Comprehensive Cancer Network recommends using the Karnofsky Performance Status (KPS) scale, an 11-level ordered scale (0-100) that assesses patients based on their health status, including activity, work, and self-care abilities, with lower KPS scores associated with poorer survival and more serious illness 10, 11

The Palliative Performance Scale (PPS) expands beyond KPS by incorporating additional domains, including ambulation 11, self-care abilities 11, and oral intake 11

The American Society of Clinical Oncology notes that both KPS and PPS have demonstrated predictive validity for survival in cancer patients, with lower scores associated with shorter survival times 12
KPS is incorporated into the Palliative Prognostic Score (PaP) along with other factors to predict 30-day survival probability 12, 13
