Consensus Statements on Precision Oncology in the China Greater Bay Area.

BACKGROUND: Next-generation sequencing comprehensive genomic panels (NGS CGPs) have enabled the delivery of tailor-made therapeutic approaches to improve survival outcomes in patients with cancer. Within the China Greater Bay Area (GBA), territorial differences in clinical practices and health care systems and strengthening collaboration warrant a regional consensus to consolidate the development and integration of precision oncology (PO). Therefore, the Precision Oncology Working Group (POWG) formulated standardized principles for the clinical application of molecular profiling, interpretation of genomic alterations, and alignment of actionable mutations with sequence-directed therapy to deliver clinical services of excellence and evidence-based care to patients with cancer in the China GBA. METHODS: Thirty experts used a modified Delphi method. The evidence extracted to support the statements was graded according to the GRADE system and reported according to the Revised Standards for Quality Improvement Reporting Excellence guidelines, version 2.0. RESULTS: The POWG reached consensus in six key statements: harmonization of reporting and quality assurance of NGS; molecular tumor board and clinical decision support systems for PO; education and training; research and real-world data collection, patient engagement, regulations, and financial reimbursement of PO treatment strategies; and clinical recommendations and implementation of PO in clinical practice. CONCLUSION: POWG consensus statements standardize the clinical application of NGS CGPs, streamline the interpretation of clinically significant genomic alterations, and align actionable mutations with sequence-directed therapies. The POWG consensus statements may harmonize the utility and delivery of PO in China's GBA.

A retrospective review for the use of palliative sedation in a regional hospital in Hong Kong.

BACKGROUND: Palliative sedation is defined as monitored use of medication intended to induce a state of decreased or absent awareness to relieve intractable suffering in a manner that is ethically acceptable to the patient, family, and health-care providers. The prevalence of palliative sedation reported ranges from 10% to 50% during in end of life care setting. There was no major review performed on the prevalence and practice of palliative sedation in Hong Kong. Besides, published guidelines and medication recommendations are developed in Caucasian settings, which may not be taken into account the cultural aspect in Chinese. Therefore, we would like to review our practice in caring terminal cancer patients to report the prevalence and practice of palliative sedation and to review factors associated with successful sedation in this group of patients. METHODS: One-hundred and eighty consecutive patients with histological or radiological evidence of malignancy who died in palliative care ward from 1st July to 30th September 2017 were screened. All patients who received continuous midazolam infusion were included. Patients' demographic data, cancer disease status, laboratory results and interview records were retrieved from electronic patient records and in-patient hospital notes. The reason for sedation, background and concurrent symptoms during sedation, and the clinical notes on symptom control during the sedation period were all reviewed. All the drug records including the dose of midazolam and other concomitant drugs, duration of palliative sedation as well as the depth of sedation were assessed. Survival data estimated from the day of admission to our department until death were recorded. RESULTS: Three hundred and thirty-nine patient-days, contributed by 81 patients out of 180 patients (45%), with midazolam infusion were studied. There was no statistical difference in the baseline characteristics of both patient groups. Median survival since admission to oncology ward in the sedated group was 11 versus 9 days in the non-sedated group (P=0.65). The median time for patients on sedation was 32.33 hours (range, 2.91-1,240 hours). Dyspnea was the most common cause of palliative sedation (78.0%), followed by delirium (40.9%). The mean dose of midazolam infusion was 10 milligram per day (range, 5-45 mg). Deranged liver function was the only statistically significant factor associated with successful sedation after multivariate analysis. CONCLUSIONS: The use of palliative sedation is safe and effective in managing refractory symptoms and is not associated with worsening of survival. Deranged liver function was associated with better symptom control. The dose of midazolam and haloperidol needed for adequate symptom control were lower than suggested in Western guidelines. Further studies on the dose requirement in Chinese population are warranted. Establishing consensus and guidelines on palliative sedation in Hong Kong should be the way forward to ensure quality care to this group of patients.
