RESUMEN
BACKGROUND: Health-related quality of life (HRQoL) is important for differentiated thyroid cancer survivors, but data for Asian survivors is lacking. This study aimed to have an overview of, and identify any disease-or treatment-related factors associated with, HRQoL in Asian differentiated thyroid cancer survivors. PATIENTS AND METHODS: Thyroid cancer survivors were recruited from the thyroid clinics at Queen Mary Hospital, Hong Kong from February 2016 to December 2016. All adult differentiated thyroid cancer patients with stable disease more than or equal to 1 year received a survey on HRQoL using the European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30) and Thyroid cancer specific quality of life (THYCA-QoL) questionnaire. Clinical information was collected retrospectively from the computerized clinical management system. To identify factors associated with poor HRQoL, univariable and stepwise multivariable regression analysis were performed. RESULTS: A total of 613 survivors completed the questionnaires (response rate: 82.1%; female: 80.1%; median survivorship: 7.4 years (range: 1.0-48.2 years)). The QLQ-C30 summary score mean was 84.4 (standard deviation (SD): 12.7) while the THYCA-QoL summary score mean was 39.9 (SD: 9.7). The 2 highest symptom subscales were fatigue (mean: 26.4, SD: 20.6) and insomnia (mean: 26.2, SD: 27.6). Factors associated with worse HRQoL included serum thyrotropin (TSH) greater than 1.0 mIU/L, unemployment, and concomitant psychiatric disorders. Concomitant psychiatric illness (n = 40/613, 6.5%) also showed significant association with most of the symptom and functional subscales. CONCLUSIONS: Fatigue and insomnia were the 2 most common symptoms experienced by our differentiated thyroid cancer survivors. Long-term survivorship care with monitoring serum TSH level, supporting return-to-work and screening for concomitant psychiatric disorders should be offered.

BACKGROUND: Tuberculosis (TB) reactivation has been increasingly identified following immune checkpoint inhibitor (ICI) therapy for cancer patients. However there has been no report on TB reactivation in the gastrointestinal tract. In the report, we describe a patient who developed TB ileitis after pembrolizumab for her metastatic nasopharyngeal carcinoma (NPC). Rechallenge with pembrolizumab after its temporary interruption together with anti-TB therapy produced continuous tumor response but without further TB reactivation. CASE PRESENTATION: A 29-year-old lady with metastatic NPC involving the cervical nodes, lungs and bones started pembrolizumab after failure to multiple lines of chemotherapy. She complained of sudden onset of abdominal pain, vomiting and bloody diarrhea with mucus 21 months after pembrolizumab. Colonoscopy revealed terminal ileitis with multiple caseating granulomas with Langerhan cells. Serum interferon gamma release assay was strongly positive. She was treated with anti-TB medication and was later rechallenged with pembrolizumab for her progressive lung metastases without further TB relapse while her lung metastases were brought under control again. CONCLUSION: To date, this is the first gastrointestinal TB reactivation after ICI therapy for cancer. Guidelines to screen for TB before initiation of ICIs in endemic areas should be established.

BACKGROUND: Training has been found effective in improving healthcare professionals' knowledge, confidence, and skills in conducting advance care planning (ACP). However, the association between training and its actual practice in the clinical setting has not been well demonstrated. To fill this gap, this paper examines the association between their readiness for ACP, in terms of perceived relevancy of ACP with their clinical work, attitudes toward and confidence and willingness to perform it, based on the Theory Planned Behavior and relevant training experiences. METHODS: An online survey about experiences about ACP of healthcare professionals, including physicians, nurses, social workers, and allied healthcare professionals, currently working in hospital and community care in Hong Kong was conducted. RESULTS: Of 250 respondents, approximately half (52.0%) had received ACP-related training. Those with relevant training reported significantly more positive in the perceived clinical relevance, willingness, and confidence in conducting ACP and different levels of agreement with 19 out of the 25 statements in a questionnaire about attitudes toward ACP than those without (ps ≤ 0.001-0.05). Respondents who received training only in a didactic format reported a significantly lower level of confidence in conducting ACP than did others who received a blended mode of learning (p = 0.012). Notwithstanding significant differences between respondents with and without relevant training, respondents generally acknowledged their roles in initiating conversations and appreciated ACP in preventing decisional conflict in surrogate decision-making regardless of their training experience. CONCLUSIONS: This paper revealed the association between training and higher level of readiness toward ACP among healthcare professionals. The findings showed that training is a predictor of their readiness for ACP in terms of perceived relevancy, willingness, and confidence. Those who had received training were less likely to consider commonly reported barriers such as time constraints, cultural taboos, and avoidance among patients and family members as hindrances to ACP implementation.

PURPOSE: Oncological care of advanced cancer patients was provided by multiple departments in Hong Kong. One of these departments, the clinical oncology department (COD), introduced systematic palliative care training for its oncologists since 2002. The COD was recognized as a European Society for Medical Oncology (ESMO) Designated Centre of Integrated Oncology and Palliative Care since 2009. This retrospective cohort study aims to review the impact of integrative training and service on palliative care coverage and outcome. METHODS: Clinical information, palliative service provision, and end-of-life outcomes of patients who passed away from lung, colorectal, liver, stomach, or breast cancer in the Hong Kong West public hospital network during July 2015 to December 2015 were collected. RESULTS: A total of 307 patients were analyzed. Around half (49.2%) were attended primarily by COD, and 68.9% received palliative service. There are significantly fewer patients referred to palliative care from other departments (p < 0.001), with only 19.9% of this patient group receiving palliative referral. COD patients had longer palliative coverage before death (median 65 days versus 24 days, p < 0.001), higher chance of receiving end-of-life care at hospice units (36.4 versus 21.2%, p = 0.003), lower ICU admission (0.66 versus 5.1%, p = 0.02), and higher percentage of receiving strong opioid in the last 30 days of life (51.0 versus 28.9%, p < 0.001) compared to other departments. In multivariable analysis, COD being the primary care team (odds ratio 12.2, p < 0.001) was associated with higher palliative care coverage. CONCLUSION: The study results suggested that systematic palliative care training of oncologists and integrative palliative service model was associated with higher palliative service coverage and improved palliative care outcomes.

BACKGROUND: The prevalence and incidence of pain and skeletal complications of metastatic bone disease such as pathologic fractures, spinal cord compression and hypercalcemia is high and an important contributor to morbidity, poor performance status and decreased quality of life. Moreover, pathologic fractures are associated with increased risk of death in people with disseminated malignancies. Therefore, prevention of pain and fractures are important goals in men with prostate cancer at risk for skeletal complications. OBJECTIVES: To assess the effects of bisphosphonates in men with bone metastases from prostate cancer. SEARCH METHODS: We identified studies by electronic search of bibliographic databases including the Cochrane Controlled Trials Register and MEDLINE on 13 July 2017 and trial registries. We handsearched the Proceedings of American Society of Clinical Oncology (to July 2017) and reference lists of all eligible trials identified. This is an update of a review last published in 2006. SELECTION CRITERIA: We included randomized controlled studies comparing the effectiveness of bisphosphonates in men with bone metastases from prostate cancer. DATA COLLECTION AND ANALYSIS: Two review authors independently extracted data and assessed the quality of trials. We defined the proportion of participants with pain response as the primary end point; secondary outcomes were skeletal-related events, mortality, quality of life, adverse events, analgesic consumption and disease progression. We assessed the quality of the evidence for the main outcomes using the GRADE approach. MAIN RESULTS: We included 18 trials reporting on 4843 participants comparing the effect of bisphosphonate administration to control regimens. PRIMARY OUTCOME: there was no clear difference in the proportion of participants with pain response (RR 1.15, 95% CI 0.93 to 1.43; P = 0.20; I2 = 0%; 3 trials; 876 participants; low quality evidence). In absolute terms, bisphosphonates resulted in a pain response in 40 more participants per 1000 (19 fewer to 114 more). SECONDARY OUTCOMES: bisphosphonates probably reduced the incidence of skeletal-related events in participants with prostate cancer metastatic to bone (RR 0.87, 95% CI 0.81 to 0.94; P = 0.27; I2 = 19%; 9 trials; 3153 participants; moderate quality evidence). In absolute terms, bisphosphonates resulted in 58 fewer SREs per 1000 (85 fewer to 27 fewer).We found no clinically relevant differences in mortality (RR 0.97, 95% CI 0.91 to 1.04; P = 0.43; I2 = 1%; 9 trials; 2450 participants; moderate quality evidence). In absolute terms, bisphosphonates resulted in 16 fewer deaths per 1000 (47 fewer to 21 more).Outcome definition of quality of life and the measurement tools varied greatly across trials and we were unable to extract any quantitative data for meta-analysis.Bisphosphonates probably increased the number of participants affected by nausea (RR 1.19, 95% CI 1.00 to 1.41; P = 0.05; I2 = 0%; 9 trials; 3008 participants; moderate quality evidence). In absolute terms, bisphosphonates resulted in seven more cases of nausea per 1000 (0 fewer to 14 more). Bisphosphonates probably increased the number of renal adverse events (RR 1.65, 95% CI 1.11 to 2.46; P = 0.01; I2 = 0%; 7 trials; 1794 participants; moderate quality evidence). In absolute terms, bisphosphonates resulted in 22 more renal adverse events per 1000 (4 more to 50 more). We found no clear difference in the number of participants with osteonecrosis of the jaw between groups (RR 1.92, 95% CI 0.75 to 4.90; P = 0.17; I2 = 0%; 5 trials; 1626 participants; very low quality evidence). In absolute terms, bisphosphonates resulted in seven more cases with osteonecrosis of the jaw per 1000 (2 fewer to 29 more). We observed no clinically relevant difference in the proportion of participants with decreased analgesic consumption (RR 1.19, 95% CI 0.87 to 1.63; P = 0.28; I2 = 37%; 4 trials; 416 participants). Statistical analysis revealed that bisphosphonates probably reduced the number of participants with disease progression (RR 0.94, 95% CI 0.90 to 0.98; P = 0.006; I2 = 0%; 7 trials; 2115 participants; moderate quality evidence). In absolute terms, bisphosphonates resulted in 36 fewer cases of disease progression per 1000 (71 fewer to 7 fewer).Findings of our predefined subgroup and sensitivity analyses were no different from those of the primary analyses. AUTHORS' CONCLUSIONS: Based on low quality evidence, there may be no clinically relevant difference in the proportion of men with pain response between bisphosphonates and control regimens in men with bone metastases from prostate cancer. Bisphosphonates probably decrease the number of skeletal-related events and disease progression. These benefits need to be weighed against the increased risk of renal impairment and nausea in men receiving bisphosphonates. Future studies should explicitly evaluate patient important outcomes such as quality of life and pain by using standardized and comparable assessment tools.

Palliative chemotherapy is increasingly used in cancer patients near end of life. With the development of newer anticancer agents which have less side effects and higher expected efficacy, the decision on palliative chemotherapy in patients near end of life is complex. This article illustrates how oncologist and palliative care physicians can work together effectively. This article also gives an overview about the risks of palliative chemotherapy near end of life, patients' and physicians' perspectives in choosing the aggressive treatment and describes what an oncologist should do when facing this challenging situation.

OBJECTIVES: We sought to identify the predictors of delayed viral clearance in patients with cancer with asymptomatic COVID-19 when the SARS-CoV-2 Omicron variants prevailed in Hong Kong. METHODS: All patients with cancer who were attending radiation therapy for head and neck malignancies or systemic anticancer therapy saved their deep throat saliva or nasopharyngeal swabs at least twice weekly for SARS-CoV-2 screening between January 1 and April 30, 2022. The multivariate analyses identified predictors of delayed viral clearance (or slow recovery), defined as >21 days for the cycle threshold values rising to ≥30 or undetectable in two consecutive samples saved within 72 hours. Three machine learning algorithms evaluated the prediction performance of the predictors. RESULTS: A total of 200 (15%) of 1309 patients tested positive for SARS-CoV-2. Age >65 years (P = 0.036), male sex (P = 0.003), high Charlson comorbidity index (P = 0.042), lung cancer (P = 0.018), immune checkpoint inhibitor (P = 0.036), and receipt of one or no dose of COVID-19 vaccine (P = 0.003) were significant predictors. The three machine learning algorithms revealed that the mean ± SD area-under-the-curve values predicting delayed viral clearance with the cut-off cycle threshold value ≥30 was 0.72 ± 0.11. CONCLUSION: We identified subgroups with delayed viral clearance that may benefit from targeted interventions.

Background: The integration of next-generation sequencing (NGS) comprehensive gene profiling (CGP) into clinical practice is playing an increasingly important role in oncology. Therefore, the HKU-HKSH Multi-disciplinary Molecular Tumour Board (MTB) was established to advance precision oncology in Hong Kong. A multicenter retrospective study investigated the feasibility of the HKU-HKSH MTB in determining genome-guided therapy for treatment-refractory solid cancers in Hong Kong. Methods: Patients who were presented at the HKU-HKSH MTB between August 2018 and June 2022 were included in this study. The primary study endpoints were the proportion of patients who receive MTB-guided therapy based on genomic analysis and overall survival (OS). Secondary endpoints included the proportion of patients with actionable genomic alterations, objective response rate (ORR), and disease control rate (DCR). The Kaplan-Meier method was used in the survival analyses, and hazard ratios were calculated using univariate Cox regression. Findings: 122 patients were reviewed at the HKU-HKSH MTB, and 63% (n = 77) adopted treatment per the MTB recommendations. These patients achieved a significantly longer median OS than those who did not receive MTB-guided therapy (12.7 months vs. 5.2 months, P = 0.0073). Their ORR and DCR were 29% and 65%, respectively. Interpretation: Our study demonstrated that among patients with heavily pre-treated advanced solid cancers, MTB-guided treatment could positively impact survival outcomes, thus illustrating the applicability of NGS CGPs in real-world clinical practice. Funding: The study was supported by the Li Shu Pui Medical Foundation. Dr Aya El Helali was supported by the Li Shu Pui Medical Foundation Fellowship grant from the Li Shu Pui Medical Foundation. Funders had no role in study design, data collection, data analysis, interpretation, or writing of the report.
RESUMEN
Emerging efficacy and safety data have led to the authorization of COVID-19 vaccines worldwide, but most trials excluded patients with active malignancies. This study evaluates the intended acceptance of COVID-19 vaccination in cancer patients in Hong Kong. METHODS: 660 adult cancer patients received a survey, in paper or electronic format, between 31 January 2021 and 15 February 2021. The survey included patient's clinical characteristics, perceptions of COVID-19 and vaccination, vaccine knowledge, cancer health literacy, and Hospital Anxiety and Depression scale (HADS). The primary outcome was the intended acceptance of COVID-19 vaccine in cancer patients. Multivariable analysis was performed to identify factors associated with intended acceptance. RESULTS: The intended acceptance of COVID-19 vaccination was 17.9%. A total of 487 (73.8%) believed that vaccination could prevent them from infection. Over 70% worried about vaccine negative effects on cancer and its side effects. Factors associated with intended acceptance included higher level of "belief in vaccine on preventing them from getting COVID-19", less worry about long-term side effects of vaccine, lower level of cancer health literacy, and normal HADS (Depression scale). CONCLUSIONS: To improve vaccine acceptance rate, public education campaigns specific to cancer patients to gain their trust in efficacy and relieve their worries are needed.
RESUMEN
PURPOSE: Radiomic models elaborate geometric and texture features of tumors extracted from imaging to develop predictors for clinical outcomes. Stereotactic body radiation therapy (SBRT) has been increasingly applied in the ablative treatment of thoracic tumors. This study aims to identify predictors of treatment responses in patients affected by early stage non-small cell lung cancer (NSCLC) or pulmonary oligo-metastases treated with SBRT and to develop an accurate machine learning model to predict radiological response to SBRT. MATERIALS AND METHODS: Computed tomography (CT) images of 85 tumors (stage I-II NSCLC and pulmonary oligo-metastases) from 69 patients treated with SBRT were analyzed. Gross tumor volumes (GTV) were contoured on CT images. Patients that achieved complete response (CR) or partial response (PR) were defined as responders. One hundred ten radiomic features were extracted using PyRadiomics module based on the GTV. The association of features with response to SBRT was evaluated. A model using support vector machine (SVM) was then trained to predict response based solely on the extracted radiomics features. Receiver operating characteristic curves were constructed to evaluate model performance of the identified radiomic predictors. RESULTS: Sixty-nine patients receiving thoracic SBRT from 2008 to 2018 were retrospectively enrolled. Skewness and root mean squared were identified as radiomic predictors of response to SBRT. The SVM machine learning model developed had an accuracy of 74.8%. The area under curves for CR, PR, and non-responder prediction were 0.86 (95% confidence interval [CI], 0.794-0.921), 0.946 (95% CI, 0.873-0.978), and 0.857 (95% CI, 0.789-0.915), respectively. CONCLUSION: Radiomic analysis of pre-treatment CT scan is a promising tool that can predict tumor response to SBRT.
RESUMEN
INTRODUCTION: Older patients experience a higher risk of treatment-related toxicity (TRT). The G8 screening tool was developed to separate cancer older patients fit to receive standard treatment from those who are frail and experiencing functional decline due to reduced organ function and multiple comorbidities. The Cancer and Aging Research Group chemotherapy toxicity tool (CARG-tt) questionnaire was developed to predict chemotherapy toxicity in geriatric patients. This prospective observational study evaluated the performance of G8 and CARG-tt in predicting severe TRT in older Chinese cancer patients. METHODS: Chinese patients aged ≥65 with a diagnosis of solid malignancy and scheduled to receive anti-cancer treatment (chemotherapy or targeted therapy) were enrolled from March 2016 to July 2017 at the Department of Clinical Oncology at Queen Mary Hospital in Hong Kong. All patients completed the G8 and CARG-tt screening and pre-treatment assessments before starting treatment. Patients were monitored for any severe TRT, which was defined by grades 3-5 using the National Cancer Institute's Common Terminology Criteria for Adverse Events v4.03, treatment discontinuation, or unexpected hospitalization from starting to 30 days after treatment. RESULTS: A total of 259 patients (male: 154, 59.5%; median age: 73.4, age range: 65-93) were enrolled in the study. Two hundred and ten (81.1%) patients received chemotherapy while the rest (n = 49, 18.9%) received targeted therapy. Overall, 146 patients (56.8%) experienced severe TRT. The mean G8 score was 12.4 (SD: 2.8). The G8 score had a significant association with unexpected admission (cutoff: 14, 41.3% vs. 26.5%, p = 0.03) but not significant in other types of TRTs. The mean CARG-tt score was 7.67 (SD: 3.7); it was not associated with severe TRTs. CONCLUSIONS: The G8 and CARG-tt demonstrated a weak prediction of severe TRT in older Chinese cancer patients. Future studies need to develop predictive tools for TRT in patients receiving novel antineoplastic therapies, with a focus on subgroup analysis for different populations.

The number of immune-related endocrine dysfunctions (irEDs) has concurrently increased with the widespread use of immunotherapy in clinical practice and further expansion of the approved indications for immune checkpoint inhibitor (ICI) in cancer management. A retrospective analysis was conducted on consecutive patients ≥18 years of age with advanced solid malignancies who had received at least one dose of anti-programmed cell death protein 1 (anti-PD-1) and/or anti-CTLA4 antibodies between January 2014 and December 2019 at a university hospital in Hong Kong. Patients were reviewed up to two months after the last administration of an ICI. The types, onset times and grades of irEDs, including hypothyroidism, hyperthyroidism, adrenal insufficiency and immune-related diabetes mellitus, were recorded. Factors associated with irEDs were identified using multivariate analysis. A total of 953 patients (male: 603, 64.0%; median age: 62.0 years) were included. Of these, 580 patients (60.9%) used ICI-alone, 132 (13.9%) used dual-ICI, 187 (19.6%) used an ICI combined with chemotherapy (chemo + ICI), and 54 (5.70%) used immunotherapy with a targeted agent (targeted + ICI). A significantly higher proportion of patients using targeted + ICI had irEDs and hypothyroidism; in contrast, a higher proportion of patients using dual-ICI had adrenal insufficiency. There was no significant difference in the incidence of irED between the younger (<65 years) and older (≥65 years) patients. Using logistic regression, only treatment type was significantly associated with irEDs. Notably, older patients had a higher risk of having immune-related diabetes mellitus. This large, real-world cohort demonstrates that targeted + ICI has a higher risk of overall irED and hypothyroidism. Immunotherapy is safe and well-tolerated regardless of age, but close monitoring of fasting glucose is essential in older populations.
RESUMEN
OBJECTIVES: The rapid ageing population of Hong Kong has a high demand on oncology and palliative care (PC) service. This study was the first territory-wide assessment in Hong Kong to assess the palliative service coverage in patients with advanced cancer in the past decade. METHODS: Cancer deaths of all 43 public hospitals of Hong Kong were screened. Randomly selected 2800 cancer deaths formed a representative cohort in all seven service clusters of Hospital Authority at 4 time points (2006, 2009, 2012, 2015). Individual patient records were thoroughly reviewed. Predictors of PC coverage was evaluated in univariable and multivariable analyses. RESULTS: From 2006 to 2015, PC coverage improved steadily from 55.4% to 68.9% (p<0.001). Median time of referral to PC service to death was 25 days (IQR: 53). For duration of inpatient PC, the median time was 22 days (IQR: 44) and it was stable over the past 10 years. Median time of referral to outpatient service to death was 74 days (IQR: 144) and there was an improvement observed (p<0.05). The current system was highly heterogeneous that PC varied between 9.8% and 84.8% in different hospitals depending on the PC service infrastructure. Multivariable Cox model identified patients associated with lower PC coverage: male, <50, rapid disease deterioration and staying in hospitals without multidisciplinary team clinic and designated palliative bed support (all p<0.01). CONCLUSION: There was concrete achievement in palliative service development in the past decade. Heterogeneity and late service provision should be addressed in future.
RESUMEN
Background: Integrated palliative care in oncology service has been widely implemented in Hong Kong since 2006. Aim: The study aimed to review its impact on end-of-life outcomes and overall survival (OS) of cancer patients, as well as its utilization of health care resources in the past 10 years. Design: Cancer deaths of all 43 public hospitals of Hong Kong were screened. Setting/Participants: Randomly selected 2800 cancer deaths formed a representative cohort in all seven service clusters of Hospital Authority at four time points (2006, 2009, 2012, and 2015). Individual patient records were thoroughly reviewed. Propensity score-matched (PSM) analysis was employed to compare the survival of patients. Results: Palliative care provision was associated with improved palliative care outcome, including more prescription of strong opioid, fewer cardiopulmonary resuscitations and intensive care unit admissions, and less futile chemotherapy usage in the end-of-life period (all p < 0.001). In the PSM analysis, the median OS in patients with palliative service (5.10 months, 95% confidence interval [CI] 4.52-5.68 months) was significantly better than those without palliative service (1.96 months, 95% CI 1.66-2.27 months). Patients in the palliative care group had more specialist clinic visits (p < 0.001) and longer hospital stay (p < 0.001) in the last six months of life, although the duration of last admission stay at acute general ward was shortened (p < 0.001). Conclusion: Our results suggested palliative care has played a role in the remarkable improvement in end-of-life outcomes and OS. However, current palliative care model relied heavily on hospital resources. Future work is needed to strengthen community care and to build up quality monitoring systems.

BACKGROUND: Immunotherapy (IO) is known to improve survival and outcome in various types of solid tumours. However, nonspecific activation of the immune system also affects various organ systems leading to the immune-related adverse events (irAEs). Systematic reviews of IO trials show that the actual incidence of irAEs may be higher than expected. Little is known about the impact of these irAEs on patients' clinical outcome, palliative care (PC) needs and hospice service use. METHODS: This is a single centre, retrospective review study of metastatic cancer patients between June 2016 to June 2017 who consecutively received immune checkpoint inhibitors with anti-PD1 in our institution. The computerized medical record, body weight chart, blood test results and in-patient assessment records were reviewed. The study was approved by the Institutional Review Board of the University of Hong Kong/ Hospital Authority Hong Kong West Cluster and conducted in compliance with the Declaration of Helsinki. RESULTS: Fifty patients received immune checkpoint inhibitors with anti-PD1 consecutively between June 2016 to June 2017 were retrospectively reviewed. The median age was 64 years old (range: 22 to 87 years old). Thirty-three of them were male (66%) patients. Twenty-five patients (50%) experienced any grade irAE. Ten patients (20%) experienced grade III/IV irAE among which 7 patients (14%) discontinued IO treatment permanently and 2 patients (4%) died due to grade III/IV toxicity. The development of grade III/ IV irAE required in-patient management, with a median duration of hospitalization of 6.5 days (range: 1 to 38 days). The response rate was 36% vs. 4% (P=0.01), median PFS (15.8 vs. 6.2 months, P=0.26), median OS (21.0 vs. 12.9 months, P=0.05) for patients with or without irAEs, respectively. The occurrence of any grade irAE was associated with a trend of improved overall survival (OS) on IO (P=0.05). Five patients (10%) developed hyper-progressive disease and received only one course of treatment before they died. Only 2 patients (4%) developed pseudo-progressive disease during treatment. Thirty-five mortalities (70%) occurred at the time of assessment of the study, of which 18 patients (36%) received PC consultations and 12 patients (24%) received hospice care before they passed away. CONCLUSIONS: Our study underscored the need for enhanced selection criteria to identify patient subgroups which benefit most from IO, and the need to involve PC and hospice services early for those non-responders or unlikely responders. Patient education and a dedicated multi-disciplinary team approach is needed to identify and treat irAE timely to prevent severe morbidities and mortalities.

BACKGROUND: Primary peritoneal ependymoma is an exceedingly rare tumour with only four cases reported in the literature. It typically follows an indolent disease course. We describe a rare case of metastatic primary peritoneal ependymoma which was treated with chemotherapy and radiotherapy resulting in prolonged survival to date for 10 years. Case Presentation. The patient was a 23-year-old female on presentation. She presented with right upper quadrant pain associated with an abdominal mass. Computed tomography demonstrated a large mass displacing the liver. Debulking surgery was done revealing a tumour arising from the peritoneum as well as multiple metastatic pleural and peritoneal nodules. Pathology was consistent with primary peritoneal ependymoma. The patient was then treated with multiple lines of chemotherapy containing etoposide as the backbone. She also received palliative radiotherapy to the thoracic metastases with good and durable response. CONCLUSION: We reported a rare case of metastatic primary peritoneal ependymoma. Etoposide containing the chemotherapy regimen is effective in the treatment of peritoneal ependymoma. Radiotherapy is also effective for palliation of local symptoms with durable response.
RESUMEN
BACKGROUND: Palliative care aims to improve the quality of life for patients and their families, by helping them to cope with problems associated with illness. It targets four aspects of health: physical, psychological, social, and spiritual. Most of the current literature on palliative care is limited to the perspectives of health professionals. This study aims to investigate the views of outpatients receiving palliative care at the Hong Kong Queen Mary Hospital Hospice Centre (HKQMHHC), which offers palliative care services to cancer patients. METHODS: This observational cross-sectional study was performed with the completion of a single paper- based original questionnaire over 18 afternoon clinic sessions on Thursdays and Fridays from December 2017 to February 2018 at the HKQMHHC. The questionnaire was designed to examine patients' perspectives; in particular, the Edmonton Symptom Assessment Scale (ESAS) was used to assess their symptoms. Descriptive and univariate analyses were performed. RESULTS: One hundred patients attending HKQMHHC were included in the study. The study revealed that all the mean scores for aspects of care offered at the centre were above 8, on a scale of 0-10 with 0 being extremely inadequate and 10 being extremely adequate. Each respondent was able to identify an average of 1.82 of the 4 aspects of palliative care. Eighty-seven percent of respondents perceived the physical aspect of this care to be of the highest priority. A negative correlation (P<0.05) was found between the extent of symptoms experienced by the patient and their satisfaction towards the services offered. CONCLUSIONS: Patients generally held very positive attitudes, reflecting that the services sufficiently met their needs. However, owing to their rather limited knowledge, this may have restricted their perspectives to a largely superficial level, as many discerned palliative care to be simply targeting physical health with medical consultations. Considering the implications of the results, the addition of accessibility and education components to Hong Kong's current system of palliative care is crucial in the betterment of such services for patients. There should also be increased local coverage of palliative care services to facilitate convenience of access. With reference to the World Health Organisation (WHO) palliative care model, the inclusion of a continued spectrum of services, such as physical and mental health activities and psychosocial counselling, should be reinforced throughout the progression of disease so as to better help patients to cope with illness. The discovery of the relationship between extent of symptoms experienced and patients' satisfaction towards services provided is a new direction for further study.
