Cardiovascular health of patients with cancer: Challenges abound. Trends Cardiovasc Med 2024:S1050-1738(24)00036-7. [PMID: 38657744 DOI: 10.1016/j.tcm.2024.04.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/09/2024] [Revised: 04/17/2024] [Accepted: 04/18/2024] [Indexed: 04/26/2024]
Abstract
Patients with cancer have elevated cardiovascular risks compared to those without cancer. As cancer incidence increases and cancer-related mortality decreases, cardiovascular diseases in patients with a history of cancer will become increasingly important. This in turn is reflected by the exponentially increasing amount of cardio-oncology research in recent years. This narrative review aims to summarize the key existing literature in several main areas of cardio-oncology, including the epidemiology, natural history, prevention, management, and determinants of the cardiovascular health of patients with cancer, and identify relevant gaps in evidence for further research.

Statin use and mortality risk in Asian patients with prostate cancer receiving androgen deprivation therapy: A population-based cohort study. Cancer Med 2023; 13:e6826. [PMID: 38140773 PMCID: PMC10807587 DOI: 10.1002/cam4.6826] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2022] [Revised: 10/31/2023] [Accepted: 12/08/2023] [Indexed: 12/24/2023] Open
Abstract
BACKGROUND This study aimed to examine the associations between the use of statins concurrent with androgen deprivation therapy (ADT) and the risks of mortality in Asian patients diagnosed with prostate cancer (PCa). METHODS Adult patients (≥18 years old) diagnosed with PCa who were receiving any form of ADT and were being treated at public hospitals in Hong Kong from December 1999 to March 2021 were retrospectively identified, with follow-up conducted until September 2021. Patients who had received medical castration for <180 days without subsequent bilateral orchidectomy, those who had used statins concurrently with ADT for <180 days, and those with missing baseline total cholesterol levels were excluded. Statin users were defined as individuals who had used statins for ≥180 days concurrent with ADT, while non-users were those who had not used any statins. PCa-related mortality was the primary outcome, while all-cause mortality served as the secondary outcome. Inverse probability treatment weighting was employed to balance the covariates. RESULTS A total of 4920 patients were included, consisting of 2578 statin users and 2342 non-users (mean age 76.1 ± 8.2 years). Over a mean follow-up period of 4.2 ± 3.3 years, it was observed that statin users had significantly lower risks of both PCa-related mortality (weighted hazard ratio [wHR] 0.56 [95% confidence interval (CI) 0.48, 0.65], p < 0.001) and all-cause mortality (wHR 0.57 [95% CI 0.51, 0.63], p < 0.001), regardless of the type of ADT used. Notably, these associations were more pronounced among patients with less advanced PCa, as indicated by the absence of androgen receptor antagonist or chemotherapy usage (p value for interaction <0.001 for both outcomes). CONCLUSION(S) The use of statins concurrent with ADT was associated with reduced mortality risks among Asian patients with PCa. These findings suggest the need for additional research to explore the potential role of statins in the treatment of PCa patients.

Major adverse cardiovascular events of enzalutamide versus abiraterone in prostate cancer: a retrospective cohort study. Prostate Cancer Prostatic Dis 2023:10.1038/s41391-023-00757-0. [PMID: 38049634 DOI: 10.1038/s41391-023-00757-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/08/2023] [Revised: 11/02/2023] [Accepted: 11/09/2023] [Indexed: 12/06/2023]
Abstract
BACKGROUND While the cardiovascular risks of androgen receptor pathway inhibitors have been studied, they were seldom compared directly. This study compares the risks of major adverse cardiovascular events (MACE) between enzalutamide and abiraterone among prostate cancer (PCa) patients. METHODS Adult PCa patients receiving either enzalutamide or abiraterone in addition to androgen deprivation therapy in Hong Kong between 1 December 1999 and 31 March 2021 were identified in this retrospective cohort study. Patients who switched between enzalutamide and abiraterone, initiated abiraterone used without steroids, or experienced prior cardiac events were excluded. Patients were followed-up until 30 September 2021. The primary outcomes were MACE, a composite of stroke, myocardial infarction (MI), Heart failure (HF), or all-cause mortality and a composite of adverse cardiovascular events (CACE) not including all-cause mortality. The secondary outcomes were individual components of MACE. Inverse probability treatment weighting was used to balance covariates between treatment groups. RESULTS In total, 1015 patients were analyzed (456 enzalutamide users and 559 abiraterone users; mean age 70.6 ± 8.8 years old) over a median follow-up duration of 11.3 (IQR: 5.3-21.3) months. Enzalutamide users had significantly lower risks of 4P-MACE (weighted hazard ratio (wHR) 0.71 [95% confidence interval (CI) 0.59-0.86], p < 0.001) and CACE (wHR 0.63 [95% CI: 0.42-0.96], p = 0.031), which remained consistent in multivariable analysis. Such an association may be stronger in patients aged ≥65 years or without diabetes mellitus and was independent of bilateral orchidectomy. Enzalutamide users also had significantly lower risks of MI (wHR 0.57 [95% CI: 0.33-0.97], p = 0.040) and all-cause mortality (wHR 0.71 [95% CI: 0.59-0.85], p < 0.001). CONCLUSION Enzalutamide was associated with lower cardiovascular risks than abiraterone in PCa patients.

Abstract
INTRODUCTION Threatened miscarriage is a common complication of pregnancy. This study aimed to assess psychological morbidity in women with threatened miscarriage, with the goal of identifying early interventions for women at risk of anxiety or depression. METHODS Women in their first trimester attending an Early Pregnancy Assessment Clinic were recruited between July 2013 and June 2015. They were asked to complete the 12-item General Health Questionnaire (GHQ-12), the Beck Depression Inventory (BDI), Spielberger's State Anxiety Inventory State form (STAI-S), the Fatigue Scale-14 (FS-14), and the Profile of Mood States (POMS) before consultation. They were also asked to rate anxiety levels before and after consultation using a visual analogue scale (VAS). RESULTS In total, 1390 women completed the study. The mean ± standard deviation of GHQ-12 (bi-modal) and GHQ-12 (Likert) scores were 4.04 ± 3.17 and 15.19 ± 5.30, respectively. Among these women, 48.4% had a GHQ-12 (bi-modal) score ≥4 and 76.7% had a GHQ-12 (Likert) score >12, indicating distress. The mean ± standard deviation of BDI, STAI-S, and FS-14 scores were 9.35 ± 7.19, 53.81 ± 10.95, and 2.40 ± 0.51, respectively. The VAS score significantly decreased after consultation (P<0.001). Compared with women without a history of miscarriage, women with a previous miscarriage had higher GHQ-12, BDI, and POMS scores (except for fatigue-inertia and vigour-activity subscales). A higher bleeding score was strongly positively correlated with GHQ-12 (Likert) score. There were weak correlations between pain score and the GHQ-12 (bi-modal) ≥4, BDI >12, and POMS scores (except for confusion-bewilderment subscale which showed a strong positive correlation). CONCLUSION Women with threatened miscarriage experience a considerable psychological burden, emphasising the importance of early recognition for timely management.

Protocol for the EACH trial: a multicentre phase II study evaluating the safety and antitumour activity of the combination of avelumab, an anti-PD-L1 agent, and cetuximab, as any line treatment for patients with recurrent/metastatic head and neck squamous cell cancer (HNSCC) in the UK. BMJ Open 2023; 13:e070391. [PMID: 38011968 PMCID: PMC10685941 DOI: 10.1136/bmjopen-2022-070391] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/22/2022] [Accepted: 07/18/2023] [Indexed: 11/29/2023] Open
Abstract
INTRODUCTION Head and neck cancer is the eighth most common cancer in the UK. Current standard of care treatment for patients with recurrent/metastatic squamous cell head and neck carcinoma (HNSCC) is platinum-based chemotherapy combined with the anti-epidermal growth factor receptor (anti-EGFR) monoclonal antibody, cetuximab. However, most patients will have poor median overall survival (OS) of 6-9 months despite treatment. HNSCC tumours exhibit an immune landscape poised to respond to immunotherapeutic approaches, with most tumours expressing the immunosuppressive receptor programmed death-ligand 1 (PD-L1). We undertook the current study to determine the safety and efficacy of avelumab, a monoclonal antibody targeting the interaction between PD-L1 and its receptor on cytotoxic T-cells, in combination with cetuximab. METHODS AND ANALYSIS This is a multi-centre, single-arm dose de-escalation phase II safety and efficacy study of avelumab combined with cetuximab; the study was to progress to a randomised phase II trial, however, the study will now complete after the safety run-in component. Up to 16 participants with histologically/cytologically recurrent/metastatic squamous cell carcinoma (including HNSCC) who have not received cetuximab previously will be recruited. All patients will receive 10 mg/kg avelumab and cetuximab (500, 400 or 300 mg/m2 depending on the cohort open at time of registration) on days 1 and 15 of 4-week cycles for up to 1 year, (avelumab not given cycle 1 day 1). A modified continual reassessment method will be used to determine dose de-escalation. The primary objective is to establish the safety of the combination and to determine the optimum dose of cetuximab. Secondary objectives include assessing evidence of antitumour activity by evaluating response rates and disease control rates at 6 and 12 months as well as progression-free and OS. ETHICS AND DISSEMINATION Approval granted by City and East REC (18/LO/0021). Findings will be published in peer-reviewed journals and disseminated at conferences. TRIAL REGISTRATION NUMBER NCT03494322.

Abstract
Objective Monoclonal antibody (Mab) treatments have significantly improved the quality and quantity of life, but they are some of the most expensive treatments, resulting in a degree of hesitancy to introduce new Mab agents. A system for estimating the effect of Mab drugs, in general, would optimally inform health strategy and fully realize how a single scientific discovery can deliver health benefits. We evaluated such a method with several well-established Mab regimens. Methods We selected five different Mab regimens in oncology and rheumatology in England. We carried out two systematic literature reviews and meta-analyses to assess health outcomes (Health Assessment Questionnaire-Disability Index for rheumatoid arthritis; overall mortality for melanoma) from real-world data and compared them to the outcomes from randomized control trials (RCTs). We applied economic modeling to estimate the net monetary benefits for health outcomes for the estimated patient population size for each Mab regimen. Results Meta-analyses of 27 eligible real-world data (RWD) sets and 26 randomized controlled trial (RCT) sets found close agreement between the observed and expected health outcomes. A Markov model showed the net positive monetary benefit in three Mab regimens and the negative benefit in two regimens. However, because of limited access to NHS data, the economic model made several assumptions about the number of treated patients and the cost of treatment to the NHS, the accuracy of which may affect the estimation of the net monetary benefit. Conclusion RCT results reliably inform the real-world experience of Mab treatments. Calculation of the net monetary benefit by the algorithm described provides a valuable overall measure of the health impact, subject to the accuracy of data inputs. This study provides a compelling case for building a comprehensive, systematized, and accessible database and related analytics, on all Mab treatments within health services.

A Single-Institution Experience of Acute Neuropathic Lumbosacral Pain in Patients Treated with Short Course Hypofractionated Radiotherapy in Locally Advanced Rectal Cancer. Int J Radiat Oncol Biol Phys 2023; 117:e312-e313.

Abstract
PURPOSE/OBJECTIVE(S) There has been increased interest in the use of short course hypofractionated radiotherapy as part of a total neoadjuvant treatment (TNT) approach in the management of rectal cancer since publication of the RAPIDO trial. However, the literature on short course radiation for rectal cancer has not reported significant acute toxicities in the weeks immediately following the completion of treatment. Anecdotally, a subset of patients has experienced acute neuropathic pain characterized in a lumbosacral distribution. This study investigates acute lumbosacral toxicity for patients receiving hypofractionated short course radiation as part of their definitive treatment for rectal cancer. MATERIALS/METHODS We retrospectively analyzed 75 patients with locally advanced rectal adenocarcinoma treated with hypofractionated short course radiation (25 Gy in 5 fractions) at our institution between 2016 and 2022. Acute toxicity caused by radiation was defined as that occurring from the start of radiation treatment to either 30 days post radiation completion, the start of chemotherapy, or date of surgery, whichever occurred first. RESULTS Among 75 patients treated with hypofractionated short course preoperative radiation with definitive intent, we identified 10 patients (13.3%) who experienced significant lumbosacral neuropathic pain and initiated a report to their medical providers during the acute toxicity time frame. Commonly, this was described as an achy pain in the bilateral buttocks radiating down to the knees or posterior claves. Patients rated this pain between moderate to extreme and management included steroids after failure of improvement with conservative measures, gabapentin, and conservative treatment with NSAIDs and Tylenol. Average time to onset of acute lumbosacral neuropathic pain was 3.7 days (SD 2.05) from start of RT. CONCLUSION We have identified a previously underappreciated acute toxicity of neuropathic lumbosacral pain in short course hypofractionated radiation therapy, which may be due to a lumbosacral plexus toxicity. Further analysis will seek to identify predictive factors such as comorbidities and dose to the lumbosacral plexus, and to determine whether there is a correlation between these observed acute toxicities and long-term outcomes.

Abstract
This article was co-authored by a patient's relative describing their experiences of receiving a diagnosis and subsequent clinical management of a rare form of prostate cancer, neuroendocrine prostate cancer (NEPC). The difficulty of receiving this diagnosis, particularly as this was terminal with no options for systemic treatment, and experiences throughout this process are detailed. The relative's questions regarding the care of her partner, NEPC and clinical management are answered. The treating physician's perspective regarding clinical management is enclosed. Prostate cancer remains one of the most common cancer diagnoses, with small-cell carcinoma (SCC) of the prostate representing 0.5-2% of these. Prostatic SCC frequently develops in patients previously treated for prostate adenocarcinoma, more rarely arising de novo. Diagnosis and management present clinical challenges owing to its rarity, frequently aggressive disease course, lack of specific diagnostic and monitoring biomarkers, and treatment limitations. Current pathophysiological understanding of prostatic SCC, genomics and contemporary and evolving treatment options in addition to current guidelines are discussed. Written principally from the patient's relatives and physician experience with discussion of current evidence, diagnostic and treatment options, we hope this piece is informative for both patients and healthcare professionals alike.

Abstract
OBJECTIVE This population-based study examined the association between baseline uric acid (UA) and prostate cancer (PCa)-related mortality amongst PCa patients receiving androgen deprivation therapy (ADT). METHODS Adults with PCa who received ADT in Hong Kong between December 1999 and March 2021 were identified. Patients with missing baseline UA were excluded. Patients were followed up until September 2021. The outcome was PCa-related mortality. RESULTS Altogether, 4126 patients (median follow-up 3.1[interquartile range 1.4-6.0] years) were included. A J-shaped association was observed between baseline UA level and PCa-related mortality risk, with a direct association in those with mean(0.401 mmol/L) or above-mean baseline UA levels (hazard ratio (HR) per standard deviation-increase 1.35 [95% confidence interval 1.21,1.51], p < 0.001), and an inverse association in those with below-mean baseline UA levels (HR 0.78[0.67,0.92], p = 0.003). The former remained significant on competing risk regression, but not the latter. CONCLUSIONS A J-shaped relationship between baseline UA level and PCa-related mortality risk was identified. This study was mainly limited by potential unmeasured and residual confounders. Further validation studies are warranted.

Abstract
BACKGROUND Medical research is important for professional advancement, and mentoring is a key means by which students and early-career doctors can engage in research. Contrasting international research collaborations, research mentoring programmes are often geographically limited. As the COVID-19 pandemic has led to increased use of online technology for classes and conferences, a virtual, international approach to medical research mentoring may be valuable. APPROACH We hereby describe our experience at the Cardiovascular Analytics Group, a virtual international medical research mentoring group established in 2015. We make use of virtual platforms in multi-level mentoring with peer mentoring and emphasise active participation, early leadership, an open culture, accessible research support and a distributed research workflow. EVALUATION With 63 active members from 14 different countries, the Group has been successful in training medical students and early-career medical graduates in academic medicine. Our members have led over 100 peer-reviewed publications of original research and reviews since 2015, winning 13 research prizes during this time. IMPLICATIONS Our accessible-distributed model of virtual international medical research collaboration and multi-level mentoring is viable and efficient and caters to the needs of contemporary healthcare. Others should consider building similar models to improve medical research mentoring globally.

Abstract
BACKGROUND Cancer is currently the second leading cause of death globally. There is much uncertainty regarding the comparative risks of new-onset overall cancer and pre-specified cancer for Type 2 diabetes mellitus (T2DM) patients on sodium-glucose cotransporter 2 inhibitors (SGLT2I) versus DPP4I. METHODS This population-based cohort study patients included patients who were diagnosed with T2DM and administered either SGLT2 or DPP4 inhibitors between 1 January 2015 and 31 December 2020 in public hospitals of Hong Kong. RESULTS This study included 60,112 T2DM patients (mean baseline age: 62.1 ± 12.4 years, male: 56.36%), of which 18,167 patients were SGLT2I users and 41,945 patients were dipeptidyl peptidase 4 inhibitor (DPP4I) users. Multivariable Cox regression found that SGLT2I use was associated with lower risks of all-cause mortality (HR: 0.92; 95% CI: 0.84-0.99; p= 0.04), cancer-related mortality (HR: 0.58; 95% CI: 0.42-0.80; p ≤ 0.001) and new diagnoses of any cancer (HR: 0.70; 95% CI: 0.59-0.84; p ≤ 0.001). SGLT2I use was associated with a lower risk of new-onset breast cancer (HR: 0.51; 95% CI: 0.32-0.80; p ≤ 0.001), but not of other malignancies. Subgroup analysis on the type of SGLT2I, dapagliflozin (HR: 0.78; 95% CI: 0.64-0.95; p = 0.01) and ertugliflozin (HR: 0.65; 95% CI: 0.43-0.98; p = 0.04) use was associated with lower risks of new cancer diagnosis. Dapagliflozin use was also linked to lower risks of breast cancer (HR: 0.48; 95% CI: 0.27-0.83; p = 0.001). CONCLUSION Sodium-glucose cotransporter 2 inhibitor use was associated with lower risks of all-cause mortality, cancer-related mortality and new-onset overall cancer compared to DPP4I use after propensity score matching and multivariable adjustment.

Abstract
BACKGROUND Although androgen deprivation therapy (ADT) is associated with cardiovascular risks, the extent and temporal trends of cardiovascular burden amongst patients with prostate cancer receiving ADT are unclear. METHODS This retrospective cohort study analyzed adults with PCa receiving ADT between 1993-2021 in Hong Kong, with follow-up until 31/9/2021 for the primary outcome of major adverse cardiovascular events (MACE; composite of cardiovascular mortality, myocardial infarction, stroke, and heart failure), and the secondary outcome of mortality. Patients were stratified into four groups by the year of ADT initiation for comparisons. RESULTS Altogether, 13,537 patients were included (mean age 75.5 ± 8.5 years old; mean follow-up 4.7 ± 4.3 years). More recent recipients of ADT had more cardiovascular risk factors and used more cardiovascular or antidiabetic medications. More recent recipients of ADT had higher risk of MACE (most recent (2015-2021) vs least recent (1993-2000) group: hazard ratio 1.33 [1.11, 1.59], P = 0.002; Ptrend < 0.001), but lower risk of mortality (hazard ratio 0.76 [0.70, 0.83], P < 0.001; Ptrend < 0.001). The 5-year risk of MACE and mortality for the most recent group were 22.5% [20.9%, 24.2%] and 52.9% [51.3%, 54.6%], respectively. CONCLUSIONS Cardiovascular risk factors were increasingly prevalent amongst patients with prostate cancer receiving ADT, with increasing risk of MACE despite decreasing mortality.

INTRODUCTION Manual vacuum aspiration is increasingly accepted as an alternative to medical or surgical evacuation of the uterus after first-trimester miscarriage. This study aimed to assess the efficacy of ultrasound-guided manual vacuum aspiration (USG-MVA) in the management of first-trimester miscarriage. METHODS This retrospective analysis included adult women with first-trimester miscarriage who underwent USG-MVA in Hong Kong between July 2015 and February 2021. The primary outcome was the efficacy of USG-MVA in terms of complete evacuation of the uterus, without the need for further medical or surgical intervention. Secondary outcomes included tolerance of the entire procedure, the success rate of karyotyping using chorionic villi, and procedural safety (ie, any clinically significant complications). RESULTS In total, 331 patients were scheduled to undergo USG-MVA for first-trimester miscarriage or incomplete miscarriage. The procedure was completed in 314 patients and well-tolerated in all of those patients. The complete evacuation rate was 94.6% (297/314), which is similar to the rate (98.1%) achieved by conventional surgical evacuation in a previous randomised controlled trial in our unit. There were no major complications. Samples from 95.2% of patients were suitable for karyotyping, which is considerably higher than the rate of suitable samples (82.9%) obtained via conventional surgical evacuation in our previous randomised controlled trial. CONCLUSION Ultrasound-guided manual vacuum aspiration is a safe and effective method to manage first-trimester miscarriage. Although it currently is not extensively used in Hong Kong, its broader clinical application could avoid general anaesthesia and shorten hospital stay.

Automatic slice thickness measurement on three types of Catphan CT phantoms. Biomed Phys Eng Express 2023; 9. [PMID: 37216929 DOI: 10.1088/2057-1976/acd785] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/08/2023] [Accepted: 05/22/2023] [Indexed: 05/24/2023]
Abstract
OBJECTIVE To develop an algorithm to measure slice thickness to run on three types of Catphan phantoms with the ability to adapt to any misalignment and rotation of the phantoms.
Method: Images of Catphan 500, 504, and 604 phantoms were examined. In addition, images with various slice thicknesses ranging from 1.5 to 10.0 mm, distance to the iso-center and phantom rotations were also examined. The automatic slice thickness algorithm was carried out by processing only objects within a circle having a diameter half that of the phantom diameter. A segmentation was performed within an inner circle with dynamic thresholds to produce binary images with wire and bead objects. Region properties were used to distinguish wire ramps and bead objects. At each identified wire ramp, the angle was detected using the Hough transform. Profile lines were then placed on each ramp based on the centroid coordinates and detected angles, and the full-width at half maximum (FWHM) determined for the average pixel profile. The slice thickness was obtained by multiplying the FWHM by the tangent of the ramp angle (23o). 
Results: Automatic measurements work well and have only a small difference (<0.5 mm) from manual measurements. For variations of slice thickness, automatic measurement successfully performs segmentation and correctly locates the profile line on all wire ramps. The results show values that are close (< 3mm) to the nominal thickness on thin slices, but less close for thicker slices. There is a strong correlation (R2 = 0.873) between automatic and manual measurements. Testing the algorithm at various distances from the iso-center and phantom rotation angle also produced accurate results. 
Conclusion: An automated algorithm for measuring slice thickness on three types of Catphan CT phantom images has been developed. The algorithm works well on various thicknesses, distances from the iso-center, and phantom rotations.

Long-term prognostic impact of cardiovascular comorbidities in patients with prostate cancer receiving androgen deprivation therapy: A population-based competing risk analysis. Int J Cancer 2023. [PMID: 37183319 DOI: 10.1002/ijc.34557] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/20/2023] [Revised: 04/14/2023] [Accepted: 04/25/2023] [Indexed: 05/16/2023]
Abstract
Our study investigated how adverse cardiovascular outcomes are impacted by cardiovascular comorbidities in patients with prostate cancer treated by androgen deprivation therapy (ADT). Using prospective, population-based data, all Hong Kong patients with prostate cancer who received ADT during 1 January 1993 to 3 March 2021 were identified and followed up for the endpoint of cardiovascular hospitalization/mortality until 31 September 2021, whichever earlier. Multivariable competing risk regression was used to compare the endpoint's cumulative incidence between different combinations of major cardiovascular comorbidities (heart failure [HF], myocardial infarction [MI], stroke and/or arrhythmia), with noncardiovascular death as competing event. Altogether, 13 537 patients were included (median age 75.9 [interquartile range 70.0-81.5] years old; median follow-up 3.3 [1.5-6.7] years). Compared to those with none of prior HF/MI/stroke/arrhythmia, the incidence of the endpoint was not different in those with only stroke (subhazard ratio [SHR] 1.06 [95% confidence interval (CI): 0.92-1.23], P = .391), but was higher in those with only HF (SHR 1.67 [1.37-2.02], P < .001), arrhythmia (SHR 1.63 [1.35-1.98], P < .001) or MI (SHR 1.43 [1.14-1.79], P = .002). Those with ≥2 of HF/MI/stroke/arrhythmia had the highest incidence of the endpoint (SHR 1.94 [1.62-2.33], P < .001), among whom different major cardiovascular comorbidities had similar prognostic impacts, with the number of comorbidities present being significantly prognostic instead. In conclusion, in patients with prostate cancer receiving ADT, the sole presence of HF, MI or arrhythmia, but not stroke, may be associated with elevated cardiovascular risks. In those with ≥2 of HF/MI/stroke/arrhythmia, the number of major cardiovascular comorbidities may be prognostically more important than the type of comorbidities.

Role of Perioperative Immune Checkpoint Inhibitors in Muscle Invasive Bladder Cancer. Oncol Ther 2023; 11:49-64. [PMID: 36595203 PMCID: PMC9935774 DOI: 10.1007/s40487-022-00218-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/17/2022] [Accepted: 12/02/2022] [Indexed: 01/04/2023] Open
Abstract
OBJECTIVE We aim to describe and highlight the current use of immune checkpoint inhibitors (ICIs) in the muscle invasive bladder cancer (MIBC) treatment landscape, particularly focusing on the perioperative setting. We provide a comprehensive review of key trials of the use of ICI in the perioperative setting, discussing trial outcomes and limitations and reviewing the role of biomarkers. INTRODUCTION ICIs have recently been integrated into the treatment algorithm for metastatic urothelial carcinoma. More than 30 published studies have investigated the role of these agents in the radical treatment of MIBC. Some studies have demonstrated conflicting results, affecting widespread adoption in clinical practice. METHODS We performed a narrative overview of the literature from databases including PubMed, MEDLINE, Embase, European society of Medical Oncology/American Society of Clinical Oncology Annual Proceedings, and clinicaltrials.gov databases up until December 2021. DISCUSSION We described the results of key trials in the neoadjuvant and adjuvant setting, some of the reasons for conflicting study results, and the implications for clinical practice. Relevant biomarkers in the field are discussed, alongside a brief overview of the immune microenvironment in bladder cancer. CONCLUSIONS Perioperative ICIs have shown promising efficacy with low toxicity in the neoadjuvant setting. The two large trials in the adjuvant setting have been contradictory. The efficacy of perioperative ICIs combined with favorable tolerability and better toxicity profile compared with chemotherapy, with the potential for biomarker-driven patient selection, may lead to a change in future practice. There is, however, a lack of long-term survival and toxicity data for those treated with ICIs, and this needs to be developed further to demonstrate an added survival benefit by using ICIs.

Abstract
AIMS Gonadotropin-releasing hormone (GnRH) agonists and antagonists, critical medications for prostate cancer (PCa) treatment, may differ in cardiovascular safety. This prospective cohort study aimed to compare the long-term cardiovascular risks between GnRH agonists and antagonists. MATERIALS AND METHODS Patients with PCa receiving GnRH agonists or antagonists during 2013-2021 in Hong Kong were identified. Patients with <6 months' prescriptions, who were switching between drugs, had missing baseline prostate-specific antigen level or had a prior stroke or myocardial infarction were excluded. Patients were followed up until September 2021. The primary outcome was major adverse cardiovascular events (MACE) as in the PRONOUNCE trial (MACEPRONOUNCE), i.e. a composite of all-cause mortality, stroke and myocardial infarction. The secondary outcome was MACECVM, i.e. a composite of cardiovascular mortality, stroke and myocardial infarction. Inverse probability treatment weighting was used to balance covariates between groups. The Log-rank test was used to compare the cumulative freedom from the primary outcome between groups. RESULTS In total, 2479 patients were analysed (162 GnRH antagonist users and 2317 agonist users; median age 75.0 years, interquartile range 68.0-81.6 years). Inverse probability treatment weighting achieved good covariate balance between groups. Over a median follow-up duration of 3.0 years (interquartile range 1.7-5.0 years), 1115 patients (45.0%) had MACEPRONOUNCE and 344 (13.9%) had MACECVM. GnRH agonist users had lower risks of MACEPRONOUNCE (Log-rank P < 0.001) and MACECVM (Log-rank P = 0.027). However, no differences were observed within 1 year of follow-up (MACEPRONOUNCE: Log-rank P = 0.308; MACECVM: Log-rank P = 0.357). Among patients without cardiovascular risk factors at baseline, GnRH agonist users had lower risks of MACEPRONOUNCE (Log-rank P < 0.001) and MACECVM (Log-rank P = 0.001), whereas no differences were observed in those with such risk factor(s) (MACEPRONOUNCE: Log-rank P = 0.569; MACECVM: Log-rank P = 0.615). CONCLUSIONS GnRH antagonists may be associated with higher long-term, but not short-term, cardiovascular risks than agonists in Asian patients with PCa, particularly in those without known cardiovascular risk factors.

Abstract
INTRODUCTION Worldwide, >130 babies have been born from ovarian tissue cryopreservation (OTC) and ovarian tissue transplantation (OTT). Ovarian tissue cryopreservation can improve quality of life among young female cancer survivors. Here, we assessed the feasibility of OTC and subsequent OTT in Hong Kong via xenografts in nude mice. METHODS This pilot study was conducted in a university-affiliated tertiary hospital. Fifty-two ovarian tissues were collected from 12 patients aged 29 to 41 years during ovarian surgery, then engrafted into 34 nude mice. The efficacies of slow freezing and vitrification were directly compared. In Phase I, non-ovariectomised nude mice underwent ovarian tissue engraftment. In Phase II, ovariectomised nude mice underwent ovarian tissue engraftment, followed by gonadotrophin administration to promote folliculogenesis. Ovarian tissue viability was assessed by gross anatomical, histological, and immunohistochemical examinations before and after OTC. Follicular density and morphological integrity were also assessed. RESULTS After OTC and OTT, grafted ovarian tissues remained viable in nude mice. Primordial follicles were observed in thawed and grafted ovarian tissues, indicating that the cryopreservation and transplantation protocols were both effective. The results were unaffected by gonadotrophin stimulation. CONCLUSION This study demonstrated the feasibility of OTC in Hong Kong as well as primordial follicle viability after OTC and OTT in nude mice. Ovarian tissue cryopreservation is ideal for patients who cannot undergo the ovarian stimulation necessary for oocyte or embryo freezing as well as prepubertal girls (all ineligible for oocyte freezing). Our findings support the clinical implementation of OTC and subsequent OTT in Hong Kong.

Metformin use and hospital attendance-related resources utilization among diabetic patients with prostate cancer on androgen deprivation therapy: A population-based cohort study. Cancer Med 2023; 12:9128-9132.

Abstract
BACKGROUND Androgen deprivation therapy (ADT), used increasingly in the treatment of prostate cancer (PCa), negatively influences glycemic control in diabetes and is associated with an increased risk of diabetes complications where hospitalization commonly ensues. Metformin could decrease the metabolic consequences of ADT and enhance its effect. This study examined the association of metformin use with healthcare resources utilization among diabetic, PCa patients receiving ADT. METHODS Diabetic adults with PCa on ADT in Hong Kong between December 1999 and March 2021 were identified. Patients with <6 months of concurrent metformin and ADT use were excluded. All included patients were followed up until September 2021. The outcomes were hospital attendances and related costs. RESULTS In total, 1,284 metformin users and 687 non-users were studied. Over 8,045 person-years, 9,049 accident and emergency (A&E), and 21,262 inpatient attendances, with 11,2781 days of hospitalization were observed. Metformin users had significantly fewer A&E attendances (incidence rate ratio (IRR): 0.61 [95% confidence interval 0.54-0.69], p < 0.001), inpatient attendances (IRR: 0.57 [0.48-0.67], p < 0.001), and days of hospitalization (IRR: 0.55 [0.42-0.72], p < 0.001). Annual attendance costs were lower for metformin users than non-users (cost ratio: 0.28 [0.10-0.80], p = 0.017). CONCLUSIONS Metformin use was associated with decreased hospital attendances, days of hospitalization, and associated costs, which could help reduce healthcare resource utilization following ADT in the treatment of PCa.

Abstract
INTRODUCTION The success in the management of germ cell tumors has encouraged researchers to pay more attention on long-term side effects and other survivorship issues. The de-escalation of treatment is intended to reduce side effects but must be balanced against any compromise of efficacy. Cisplatin-based therapy is the cornerstone of treatment for germ cell tumors. However, they can result in acute and long-term side effects, including ototoxicity, neurotoxicity, nephrotoxicity, and increased risk of second malignancies. AREAS COVERED This review discusses approaches of de-escalation including biomarker-directed treatment using microRNAs, surveillance for immature teratoma, the use of carboplatin monotherapy for seminoma, and the option of non-cisplatin-based approaches in relapsed germ cell tumors. EXPERT OPINION While the results with the current standard options in terms of cancer control are very good, the price being paid in terms of long-term side effects is considerable.

Abstract
BACKGROUND Immune checkpoint inhibitors (ICIs) are increasingly established cancer therapeutics, but they are associated with new-onset diabetes mellitus (DM). Such risks have not been adequately quantified, and between-class and -sex differences remain unexplored. METHODS This was a prospective cohort study of cancer patients receiving any ICI in Hong Kong between 2013 and 2021. Patients with known DM were excluded. Due to few patients using other ICIs, only programmed cell death 1 inhibitors (PD-1i) and programmed death ligand 1 inhibitors (PD-L1i) were compared, alongside between-sex comparison. When comparing PD-1i against PD-L1i, patients with the use of other ICIs or both PD-1i and PD-L1 were further excluded. Inverse probability treatment weighting (IPTW) was used to minimize between-group covariate imbalances. RESULTS Altogether, 3375 patients were analyzed (65.2% males, median age 62.2 [interquartile range 53.8-69.5] years old). Over a median follow-up of 1.0 [0.4-2.4] years, new-onset DM occurred in 457 patients (13.5%), with a 3-year risk of 14.5% [95% confidence interval 13.3%, 15.8%]. IPTW achieve acceptable covariate balance between sexes, and between PD-1i (N = 622) and PD-L1i (N = 2426) users. Males had significantly higher risk of new-onset DM (hazard ratio 1.35 [1.09, 1.67], p = 0.006), while PD-1i and PD-L1i users did not have significantly different risks (hazard ratio vs PD-L1i 0.81 [0.59, 1.11], p = 0.182). These were consistent in those with at least 1 year of follow-up, and on competing risk regression. CONCLUSION Users of ICI may have a substantial risk of new-onset DM, which may be higher in males but did not differ between PD-1i and PD-L1i.

Abstract
BACKGROUND This study aims to examine the associations between metformin use concurrent with androgen deprivation therapy (ADT) and mortality risks in Asian, diabetic patients with prostate cancer (PCa). METHODS This study identified diabetic adults with PCa receiving any ADT attending public hospitals in Hong Kong between December 1999 and March 2021 retrospectively, with follow-up until September 2021. Patients with <6 months of medical castration without subsequent bilateral orchidectomy, <6 months of concurrent metformin use and ADT, or missing baseline HbA1c were excluded. Metformin users had ≥180 days of concurrent metformin use and ADT, while non-users had no concurrent metformin use and ADT or never used metformin. The primary outcome was PCa-related mortality. The secondary outcome was all-cause mortality. The study used inverse probability treatment weighting to balance covariates. RESULTS The analyzed cohort consisted of 1971 patients (1284 metformin users and 687 non-users; mean age 76.2 ± 7.8 years). Over a mean follow-up of 4.1 ± 3.2 years, metformin users had significantly lower risks of PCa-related mortality (weighted hazard ratio [wHR]: 0.49 [95% confidence interval, CI: 0.39-0.61], p < 0.001) and all-cause mortality (wHR 0.53 [0.46-0.61], p < 0.001), independent of diabetic control or status of chronic kidney disease. Such effects appeared stronger in patients with less advanced PCa, which is reflected by the absence of androgen receptor antagonist or chemotherapy use (p value for interaction: 0.017 for PCa-related mortality; 0.048 for all-cause mortality). CONCLUSIONS Metformin use concurrent with ADT was associated with lower risks of mortality in Asian, diabetic patients with PCa.

Abstract
Background Advanced head and neck squamous cell carcinoma (HNSCC) is associated with a poor prognosis, and biomarkers that predict response to treatment are highly desirable. The primary aim was to predict progression-free survival (PFS) with a multivariate risk prediction model. Methods Experimental covariates were derived from blood samples of 56 HNSCC patients which were prospectively obtained within a Phase 2 clinical trial (NCT02633800) at baseline and after the first treatment cycle of combined platinum-based chemotherapy with cetuximab treatment. Clinical and experimental covariates were selected by Bayesian multivariate regression to form risk scores to predict PFS. Results A 'baseline' and a 'combined' risk prediction model were generated, each of which featuring clinical and experimental covariates. The baseline risk signature has three covariates and was strongly driven by baseline percentage of CD33+CD14+HLADRhigh monocytes. The combined signature has six covariates, also featuring baseline CD33+CD14+HLADRhigh monocytes but is strongly driven by on-treatment relative change of CD8+ central memory T cells percentages. The combined model has a higher predictive power than the baseline model and was successfully validated to predict therapeutic response in an independent cohort of nine patients from an additional Phase 2 trial (NCT03494322) assessing the addition of avelumab to cetuximab treatment in HNSCC. We identified tissue counterparts for the immune cells driving the models, using imaging mass cytometry, that specifically colocalized at the tissue level and correlated with outcome. Conclusions This immune-based combined multimodality signature, obtained through longitudinal peripheral blood monitoring and validated in an independent cohort, presents a novel means of predicting response early on during the treatment course.

Abstract
BACKGROUND Although androgen deprivation therapy has known cardiovascular risks, it is unclear if its duration is related to cardiovascular risks. This study thus aimed to investigate the associations between gonadotrophin-releasing hormone (GnRH) agonist use duration and cardiovascular risks. METHODS This retrospective cohort study included adult patients with prostate cancer receiving GnRH agonists in Hong Kong during 1999-2021. Patients who switched to GnRH antagonists, underwent bilateral orchidectomy, had <6 months of GnRH agonist, prior myocardial infarction (MI), or prior stroke was excluded. All patients were followed up until September 2021 for a composite endpoint of MI and stroke. Multivariable competing-risk regression using the Fine-Gray subdistribution model was used, with mortality from any cause as the competing event. RESULTS In total, 4038 patients were analyzed (median age 74.9 years old, interquartile range (IQR) 68.7-80.8 years old). Over a median follow-up of 4.1 years (IQR 2.1-7.5 years), longer GnRH agonists use was associated with higher risk of the endpoint (sub-hazard ratio per year 1.04 [1.01-1.06], p = 0.001), with those using GnRH agonists for ≥2 years having an estimated 23% increase in the sub-hazard of the endpoint (sub-hazard ratio 1.23 [1.04-1.46], p = 0.017). CONCLUSION Longer GnRH agonist use may be associated with greater cardiovascular risks.

Diabetes mellitus is associated with the development of pancreatic cancer, but few large-scale studies have examined its predictive risk factors. The present study aims to examine the predictors for PaC in patients with type 2 diabetes mellitus in a territory-wide retrospective cohort study.
Methods
This was a territory-wide retrospective cohort study of patients with type 2 diabetes mellitus over the age of 40 and no prior history of pancreatic cancer. Baseline demographics, use of anti-diabetic medications, comorbidities and biochemical parameters were extracted. Cox regression was used to calculate hazard ratios (HR) with 95% confidence intervals (CI). Subgroup analyses based on chronic kidney disease stages were performed.
Results
This study consisted of 273738 patients (age = 65.4 ± 12.7 years old, male = 48.2%, follow-up duration = 3547 ± 1207 days, disease duration = 4.8 ± 2.3 years), amongst which 1148 developed pancreatic cancer. The number of anti-diabetic medications prescribed (HR: 1.20; 95% CI: 1.01-1.42; P = 0.040), diabetic microvascular complications (HR: 1.91; 95% CI: 1.30-2.81; P < 0.001), chronic kidney disease (HR: 1.81; 95% CI: 1.25-2.64; P = 0.002), use of acarbose (HR: 2.24; 95% CI: 1.35-3.74; P = 0.002) and use of glucagon-like peptide-1 receptor agonist (HR: 4.00; 95% CI: 1.28-12.53, P = 0.017) were associated with pancreatic cancer development on multivariable Cox regression adjusting for the duration of diabetes mellitus, mean HbA1c, and history of pancreatic diseases. Stage 3A chronic kidney disease or below was associated with pancreatic cancer but not stage 3B or beyond.
Conclusion
Diabetic microvascular complications, especially stage 1, 2 and 3A chronic kidney disease, were associated with pancreatic cancers.

Abstract
Immune checkpoint inhibitors (ICI) have known associations with cardiotoxicity. However, a representative quantification of the adverse cardiovascular events and cardiovascular attendances amongst Asian users of ICI has been lacking. This retrospective cohort study identified all ICI users in Hong Kong, China, between 2013-2021. All patients were followed up until the end of 2021 for the primary outcome of major adverse cardiovascular event (MACE; a composite of cardiovascular mortality, myocardial infarction, heart failure, and stroke). Patients with prior diagnosis of any component of MACE were excluded from all MACE analyses. In total, 4324 patients were analysed (2905 (67.2%) males; median age 63.5 years old (interquartile range 55.4-70.7 years old); median follow-up 1.0 year (interquartile range 0.4-2.3 years)), of whom 153 were excluded from MACE analyses due to prior events. MACE occurred in 116 (2.8%) with an incidence rate (IR) of 1.7 [95% confidence interval: 1.4, 2.0] events per 100 patient-years; IR was higher within the first year of follow-up (2.9 [2.3, 3.5] events per 100 patient-years). Cardiovascular hospitalization(s) occurred in 188 (4.4%) with 254 episodes (0.5% of all episodes) and 1555 days of hospitalization (1.3% of all hospitalized days), for whom the IR of cardiovascular hospitalization was 5.6 [4.6, 6.9] episodes per 100 person-years with 52.9 [39.8, 70.3] days' stay per 100 person-years. Amongst Asian users of ICI, MACE was uncommon, and a small proportion of hospitalizations was cardiovascular in nature. Most MACE and cardiovascular hospitalizations occurred during the first year after initiating ICI.

Evaluation of prognostic risk models for postoperative pulmonary complications in adult patients undergoing major abdominal surgery: a systematic review and international external validation cohort study. Lancet Digit Health 2022; 4:e520-e531. [PMID: 35750401 DOI: 10.1016/s2589-7500(22)00069-3] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/15/2021] [Revised: 01/07/2022] [Accepted: 04/06/2022] [Indexed: 06/15/2023]
Abstract
BACKGROUND Stratifying risk of postoperative pulmonary complications after major abdominal surgery allows clinicians to modify risk through targeted interventions and enhanced monitoring. In this study, we aimed to identify and validate prognostic models against a new consensus definition of postoperative pulmonary complications. METHODS We did a systematic review and international external validation cohort study. The systematic review was done in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We searched MEDLINE and Embase on March 1, 2020, for articles published in English that reported on risk prediction models for postoperative pulmonary complications following abdominal surgery. External validation of existing models was done within a prospective international cohort study of adult patients (≥18 years) undergoing major abdominal surgery. Data were collected between Jan 1, 2019, and April 30, 2019, in the UK, Ireland, and Australia. Discriminative ability and prognostic accuracy summary statistics were compared between models for the 30-day postoperative pulmonary complication rate as defined by the Standardised Endpoints in Perioperative Medicine Core Outcome Measures in Perioperative and Anaesthetic Care (StEP-COMPAC). Model performance was compared using the area under the receiver operating characteristic curve (AUROCC). FINDINGS In total, we identified 2903 records from our literature search; of which, 2514 (86·6%) unique records were screened, 121 (4·8%) of 2514 full texts were assessed for eligibility, and 29 unique prognostic models were identified. Nine (31·0%) of 29 models had score development reported only, 19 (65·5%) had undergone internal validation, and only four (13·8%) had been externally validated. Data to validate six eligible models were collected in the international external validation cohort study. Data from 11 591 patients were available, with an overall postoperative pulmonary complication rate of 7·8% (n=903). None of the six models showed good discrimination (defined as AUROCC ≥0·70) for identifying postoperative pulmonary complications, with the Assess Respiratory Risk in Surgical Patients in Catalonia score showing the best discrimination (AUROCC 0·700 [95% CI 0·683-0·717]). INTERPRETATION In the pre-COVID-19 pandemic data, variability in the risk of pulmonary complications (StEP-COMPAC definition) following major abdominal surgery was poorly described by existing prognostication tools. To improve surgical safety during the COVID-19 pandemic recovery and beyond, novel risk stratification tools are required. FUNDING British Journal of Surgery Society.

Abstract
BACKGROUND Pancreatic cancer presents as advanced disease in >80% of patients; yet, appropriate ages to consider prevention and early detection strategies are poorly defined. We investigated age-specific associations and attributable risks of pancreatic cancer for established modifiable and non-modifiable risk factors. PATIENTS AND METHODS We included 167 483 participants from two prospective US cohort studies with 1190 incident cases of pancreatic cancer during >30 years of follow-up; 5107 pancreatic cancer cases and 8845 control participants of European ancestry from a completed multicenter genome-wide association study (GWAS); and 248 893 pancreatic cancer cases documented in the US Surveillance, Epidemiology, and End Results (SEER) Program. Across different age categories, we investigated cigarette smoking, obesity, diabetes, height, and non-O blood group in the prospective cohorts; weighted polygenic risk score of 22 previously identified single nucleotide polymorphisms in the GWAS; and male sex and black race in the SEER Program. RESULTS In the prospective cohorts, all five risk factors were more strongly associated with pancreatic cancer risk among younger participants, with associations attenuated among those aged >70 years. The hazard ratios comparing participants with three to five risk factors with those with no risk factors were 9.24 [95% confidence interval (CI) 4.11-20.77] among those aged ≤60 years, 3.00 (95% CI 1.85-4.86) among those aged 61-70 years, and 1.46 (95% CI 1.10-1.94) among those aged >70 years (Pheterogeneity = 3×10-5). These factors together were related to 65.6%, 49.7%, and 17.2% of incident pancreatic cancers in these age groups, respectively. In the GWAS and the SEER Program, the associations with the polygenic risk score, male sex, and black race were all stronger among younger individuals (Pheterogeneity ≤0.01). CONCLUSIONS Established risk factors are more strongly associated with earlier-onset pancreatic cancer, emphasizing the importance of age at initiation for cancer prevention and control programs targeting this highly lethal malignancy.

Abstract
BackgroundApproximately 30% of patients (pts) with plaque psoriasis (PsO) develop psoriatic arthritis (PsA)1, which is associated with high Psoriasis Area and Severity Index (PASI) and nail involvement. The Psoriasis Study of Health Outcomes (PSoHO) is a 3-year (yr), international, prospective, observational cohort study comparing the effectiveness of anti-IL-17A biologics to all other approved biologics in pts with moderate-to-severe PsO.ObjectivesThis interim subset analysis describes the baseline characteristics and Week 12 (W12) effectiveness in pts with moderate-to-severe PsO and PsA in PSoHO.MethodsAdults with moderate-to-severe PsO for ≥6 months who initiated/switched biologic treatment during routine medical care were enrolled. PsA diagnosis was recorded by the dermatologists based on the medical history and/or information provided by the patient. W12 effectiveness was assessed by the proportion of pts achieving almost clear or clear skin defined by ≥90% improvement in PASI, affected Body Surface Area (BSA), Dermatology Life Quality Index (DLQI), and Patient Global Assessment of Disease Severity (PatGA). Musculoskeletal endpoints were not collected. Data were analysed descriptively, using mean (standard deviation [SD]) or median ([Q1/Q3]) for continuous variables and n, % and 95% confidence limits for categorical variables.ResultsOverall, 1981 pts were enrolled in this study, of whom 461 (23.3%) had a PsA diagnosis and received either anti-IL-17A (n=227; 49.2%) or other biologics (n=234; 50.8%). This subset of pts had a mean age of 48.7 yrs and a median disease duration of 18.9 yrs for PsO and 5.6 yrs for PsA (Table 1).Table 1.Baseline characteristics for PsO patients with PsA.

Abstract
BackgroundLupus low disease activity state (LLDAS) attainment has been reported to be associated with reduced damage accrual, flare, and mortality, as well as improved quality of life, in cohorts of SLE patients with established disease. Whether these associations are present in recent-onset disease is less well known.ObjectivesTo evaluate the associations of LLDAS attainment with outcomes in patients with recent onset SLE.MethodsData from a 13-country longitudinal SLE cohort (ACR/SLICC criteria) were collected prospectively between 2013 and 2020 using standard templates. Organ damage and flare were captured using SLICC Damage Index and SELENA-SLEDAI Flare Index, respectively. LLDAS was defined as Golder et al., 2019 [1]. An inception cohort was defined based on duration since SLE diagnosis<1 year at enrolment. Patient characteristics between inception and non-inception cohorts were compared using Wilcoxon rank-sum (continuous variables) or Pearson’s Chi-squared tests (categorical variables). Survival analyses were performed to examine the association between LLDAS attainment and damage accrual and flare.ResultsThe study cohort included 4,106 patients of whom 680 (16%) were recruited within 1 year of SLE diagnosis (inception cohort). Compared to the non-inception cohort, inception cohort patients were significantly younger, had higher disease activity (SLEDAI-2K and physician global assessment), used more glucocorticoids and immunosuppressants but had less organ damage at enrolment and only 88 (13.6%) patients accrued damage during a median 2.2 years follow-up (Table 1).Table 1.Non-inception cohortInception cohortp-valuen=3426n=680Age at enrolment (years), median [IQR]40 [31, 51]33 [25, 44]<0.001Age at diagnosis (years), median [IQR]28 [21, 38]33 [25, 43]<0.001SLE duration at enrolment (years), median [IQR]10 [5, 16]1 [0, 1]<0.001Study duration (years), median [IQR]2.5 [1.0, 5.4]2.2 [0.9, 3.7]<0.001Females, n (%)3155 (92.1%)623 (91.6%)0.68Asian ethnicity, n (%)3037 (89.1%)595 (88.1%)0.49Prednisolone (PNL) use - ever, n (%)2865 (83.6%)620 (91.2%)<0.001Time adjusted mean (TAM)-PNL, median [IQR]5.0 [2.2, 8.6]6.2 [3.2, 10.3]<0.001Cumulative PNL (g), median [IQR]3.4 [0.5, 9.7]3.8 [1.1, 8.5]0.26Anti-Malarial use - ever, n (%)2669 (77.9%)569 (83.7%)<0.001Immunosupressant use -ever, n (%)2367 (69.1%)521 (76.6%)<0.001AMS (TAM-SLEDAI-2K), median [IQR]2.8 [1.2, 4.6]3.1 [1.6, 5.0]0.002TAM-PGA, median [IQR]0.4 [0.2, 0.7]0.4 [0.3, 0.8]<0.001Mild/moderate/severe flare ever, n (%)1789 (52.2%)391 (57.5%)0.012Organ damage accrual, n (%)629 (20.8%)88 (13.6%)<0.001LLDAS at baseline, n (%)1730 (50.5%)195 (28.7%)<0.001LLDAS-ever (at least once), n (%)2637 (78.2%)492 (73.9%)0.014≥50% time in LLDAS (LLDAS-5), n (%)1612 (50.6%)256 (41.1%)<0.001Significantly fewer inception cohort patients were in LLDAS at enrolment than the non-inception cohort (29% vs. 51%, p<0.001). However, 74% of inception and 78% of non-inception cohort patients achieved LLDAS at least once during follow-up. Limiting analysis only to patients not in LLDAS at enrolment, time to first LLDAS attainment was assessed: inception cohort patients were 60% more likely to attain their first LLDAS (HR = 1.60 (95%CI: 1.40, 1.82), p<0.001) than non-inception cohort patients. LLDAS attainment was significantly protective against flare in the inception (HR, 95% CI) and non-inception (HR, 95% CI) cohorts. Trends towards protection against damage accrual in association with LLDAS in the inception cohort were not significant.ConclusionLLDAS attainment is protective from flare in recent onset SLE. Significant protection from damage accrual was not observed, due to low rates of damage accrual in the first years after SLE diagnosis.References[1]Golder, V., et al., Lupus low disease activity state as a treatment endpoint for systemic lupus erythematosus: a prospective validation study.

Risk of New-Onset Prostate Cancer for Metformin Versus Sulfonylurea Use in Type 2 Diabetes Mellitus: A Propensity Score-Matched Study. J Natl Compr Canc Netw 2022; 20:674-682.e15. [PMID: 35714677 DOI: 10.6004/jnccn.2022.7010] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/22/2021] [Accepted: 02/23/2022] [Indexed: 11/17/2022]
Abstract
BACKGROUND The aim of this study was to compare the risks of new-onset prostate cancer between metformin and sulfonylurea users with type 2 diabetes mellitus (T2DM). METHODS This population-based retrospective cohort study included male patients with T2DM presenting to public hospitals/clinics in Hong Kong between January 1, 2000, and December 31, 2009. We only included patients prescribed either, but not both, metformin or sulfonylurea. All patients were followed up until December 31, 2019. The primary outcome was new-onset prostate cancer and the secondary outcome was all-cause mortality. One-to-one propensity score matching was performed between metformin and sulfonylurea users based on demographics, comorbidities, antidiabetic and cardiovascular medications, fasting blood glucose level, and hemoglobin A1c level. Subgroup analyses based on age and use of androgen deprivation therapy were performed. RESULTS The final study cohort consisted of 25,695 metformin users (mean [SD] age, 65.2 [11.8] years) and 25,695 matched sulfonylurea users (mean [SD] age, 65.3 [11.8] years) with a median follow-up duration of 119.6 months (interquartile range, 91.7-139.6 months) after 1:1 propensity score matching of 66,411 patients. Metformin users had lower risks of new-onset prostate cancer (hazard ratio, 0.80; 95% CI, 0.69-0.93; P=.0031) and all-cause mortality (hazard ratio, 0.89; 95% CI, 0.86-0.92; P<.0001) than sulfonylurea users. Metformin use was more protective against prostate cancer but less protective against all-cause mortality in patients aged <65 years (P for trend <.0001 for both) compared with patients aged ≥65 years. Metformin users had lower risk of all-cause mortality than sulfonylurea users, regardless of the use of androgen deprivation therapy (P for trend <.0001) among patients who developed prostate cancer. CONCLUSIONS Metformin use was associated with significantly lower risks of new-onset prostate cancer and all-cause mortality than sulfonylurea use in male patients with T2DM.

Abstract
BackgroundSystemic lupus erythematosus (SLE) is a chronic, autoimmune disease of an unknown etiology with a broad spectrum of organ manifestations, and patients with SLE have limited treatment options to NSAIDS, glucocorticoids, hydroxychloroquine and immunosuppressants. There is a lack of real-world evidence related to treatment patterns of SLE patients in Taiwan.ObjectivesTo describe the real-world patient demographics, clinical characteristics, and treatment patterns of patients with SLE in Taiwan.MethodsA retrospective observational study using Taiwan’s National Health Insurance Research Database (NHIRD) from 1/1/2014 to 12/31/2019 was undertaken. Patients holding catastrophic illness certificates for SLE in 2015-2017 were identified. Enrolled patients aged ≥ 18 years were then divided into three groups (mild, moderate, and severe) based on the highest severity patients experienced in the one year following the enrollment date using a published claims-based algorithm (Garris et al 2013) that incorporates the Systemic Lupus Erythematosus Disease Activity Index, Systemic Lupus Activity Measure, British Isles Lupus Assessment Group Index and expert clinical opinion, and indexed upon the first date of entering the severity group. Baseline patient characteristics and treatment patterns during the follow-up period were measured. The types of treatment considered were NSAIDs, glucocorticoids, hydroxychloroquine and immunosuppressants.ResultsA total of 20,181 patients with catastrophic illness certificates for SLE were included in this study. The mean age of all SLE patients was 46.5 years and patients were mostly female (89.1%). The mean Charlson Comorbidity Index (CCI) score of all SLE patients was 1.5 (SD 1.3). Of these patients, 29.3% (n=5,918) had mild SLE activity, 60.7% (n=12,253) moderate and 10.0% (n=2,010) severe. During the one-year follow-up period, moderate to severe patients had numerically higher utilization rate of all types of treatment compared with mild patients (Table 1). Of all oral glucocorticoid users,27.8% of severe patients used high-dose glucocorticoids (> 15 mg/day) compared to <0.1% for mild and 9.7% for moderate patients. More than 70.0% of moderate to severe patients were prescribed 2 or more types of treatment at the same point of time. Of these patients having concomitant treatment of glucocorticoids with immunosuppressants, glucocorticoid dosage increased with the number of immunosuppressant used, especially in severe patients. 80.4% of moderate to severe patients received glucocorticoid-based therapy as the first-line treatment and the median treatment duration was 3.1 months. The median treatment duration of each first-line immunosuppressant ranged from 0.9 to 4.8 months in moderate to severe patients.Table 1.SLE treatment utilization during the 1-year follow-up periodTotal (n=20,181)`Mild (n=5,918)Moderate (n=12,253)Severe (n=2,010)n%n%n%n%NSAID7,21235.71,40523.74,98340.782441.0Glucocorticoid14,01969.52,01534.110,29784.01,70784.9Hydroxychloroquine13,27865.82,86748.58,97073.21,44171.7Immunosuppressant7,63037.800.06,31951.61,31165.2Methotrexate8984.500.07866.41125.6Azathioprine5,64228.000.04,84339.579939.8Leflunomide1320.700.01171.0150.8Cyclosporin8544.200.07155.81396.9Mycophenolate9594.800.07746.31859.2Cyclophosphamide7903.900.0170.177338.5ConclusionThe complexity and intensity of therapeutic approaches in SLE were associated with increased disease severity and patients were often resistant to treatment. These findings reflect the disease burden in SLE patients and suggest there is a substantial unmet need in the SLE treatment paradigm for moderate to severe SLE patients.References[1]Garris C, et al.

HER2 Mediates PSMA/mGluR1-Driven Resistance to the DS-7423 Dual PI3K/mTOR Inhibitor in PTEN Wild-type Prostate Cancer Models. Mol Cancer Ther 2022; 21:667-676. [PMID: 35086953 PMCID: PMC7612588 DOI: 10.1158/1535-7163.mct-21-0320] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/11/2021] [Revised: 10/15/2021] [Accepted: 01/19/2022] [Indexed: 12/24/2022]
Abstract
Prostate cancer remains a major cause of male mortality. Genetic alteration of the PI3K/AKT/mTOR pathway is one of the key events in tumor development and progression in prostate cancer, with inactivation of the PTEN tumor suppressor being very common in this cancer type. Extensive evaluation has been performed on the therapeutic potential of PI3K/AKT/mTOR inhibitors and the resistance mechanisms arising in patients with PTEN-mutant background. However, in patients with a PTEN wild-type phenotype, PI3K/AKT/mTOR inhibitors have not demonstrated efficacy, and this remains an area of clinical unmet need. In this study, we have investigated the response of PTEN wild-type prostate cancer cell lines to the dual PI3K/mTOR inhibitor DS-7423 alone or in combination with HER2 inhibitors or mGluR1 inhibitors. Upon treatment with the dual PI3K/mTOR inhibitor DS-7423, PTEN wild-type prostate cancer CWR22/22RV1 cells upregulate expression of the proteins PSMA, mGluR1, and the tyrosine kinase receptor HER2, while PTEN-mutant LNCaP cells upregulate androgen receptor and HER3. PSMA, mGluR1, and HER2 exert control over one another in a positive feedback loop that allows cells to overcome treatment with DS-7423. Concomitant targeting of PI3K/mTOR with either HER2 or mGluR1 inhibitors results in decreased cell survival and tumor growth in xenograft studies. Our results suggest a novel therapeutic possibility for patients with PTEN wild-type PI3K/AKT-mutant prostate cancer based in the combination of PI3K/mTOR blockade with HER2 or mGluR1 inhibitors.

Osimertinib and anti-HER3 combination therapy engages immune dependent tumor toxicity via STING activation in trans. Cell Death Dis 2022; 13:274.

Abstract
Over the past decade, immunotherapy delivered novel treatments for many cancer types. However, lung cancer still leads cancer mortality, and non-small-cell lung carcinoma patients with mutant EGFR cannot benefit from checkpoint inhibitors due to toxicity, relying only on palliative chemotherapy and the third-generation tyrosine kinase inhibitor (TKI) osimertinib. This new drug extends lifespan by 9-months vs. second-generation TKIs, but unfortunately, cancers relapse due to resistance mechanisms and the lack of antitumor immune responses. Here we explored the combination of osimertinib with anti-HER3 monoclonal antibodies and observed that the immune system contributed to eliminate tumor cells in mice and co-culture experiments using bone marrow-derived macrophages and human PBMCs. Osimertinib led to apoptosis of tumors but simultaneously, it triggered inositol-requiring-enzyme (IRE1α)-dependent HER3 upregulation, increased macrophage infiltration, and activated cGAS in cancer cells to produce cGAMP (detected by a lentivirally transduced STING activity biosensor), transactivating STING in macrophages. We sought to target osimertinib-induced HER3 upregulation with monoclonal antibodies, which engaged Fc receptor-dependent tumor elimination by macrophages, and STING agonists enhanced macrophage-mediated tumor elimination further. Thus, by engaging a tumor non-autonomous mechanism involving cGAS-STING and innate immunity, the combination of osimertinib and anti-HER3 antibodies could improve the limited therapeutic and stratification options for advanced stage lung cancer patients with mutant EGFR.

Abstract
Abstract
Introduction
The completion of a Do Not Attempt Cardio-Pulmonary Resuscitation (DNACPR) form represents an important part of patient care. However, this can be a sensitive process that has gained national media interest. The aim of this Quality Improvement (QI) Project was to improve the quality of DNACPR form completion in a Care of the Elderly Department.
Methods
The QI project ran from May 2019 to January 2021 and was overseen by a multi-disciplinary team (including patient representation). DNACPR forms on the Care of the Elderly wards were audited monthly against 7 standards which correspond to key sections on the DNACPR form. During the data collection process, interventions were implemented using Plan-Do-Study-Act cycles. Interventions included: appointing ‘DNACPR Champions’ to complete monthly audits and provide personalised clinician feedback, the introduction of a new mandatory e-learning module, the creation of an alert system on nerve centre (the Trust’s electronic handover system) and the development of new DNACPR patient information including webpage development, videos and leaflets.
Results
The project has led to sustained improvements in majority of the 7 standards. The biggest improvements were seen in the inclusion of a review date, correct completion of the mental capacity assessment and the use of patient information leaflets. The documentation of discussions with patient and relatives remained below the audit standards and was largely unchanged during the QI project.
Conclusion
A multi-disciplinary and multi-faceted QI approach has shown to improve the quality of DNACPR form completion. Further work is needed to continue this process and a focus on staff training and ward-level processes will be the priority.

Abstract
417 Background: Following relapse from first line chemotherapy, 30-60% of patients with germ cell tumors (GCTs) can be salvaged with further chemotherapy. Oxaliplatin-based therapies may offer reduced toxicity. Methods: Eligible patients with GCTs who progressed following cisplatin-based chemotherapy were recruited into this single-arm, phase II clinical trial (NCT01782339). Participants were recruited from six centers and received four 21-day cycles of: Actinomycin D 1mg/m2, high dose Methotrexate 5-8g/m2 day 1, Paclitaxel 80mg/m2 days 1, 8 and 15, Oxaliplatin 85mg/m2 days 4 and 8 with Pegfilgrastim support. Participants underwent an FDG-PET scan at baseline, prior to cycle 2 and on completion of treatment. The primary endpoint was objective response rate (ORR). Secondary endpoints were progression-free survival (PFS), overall survival (OS) and toxicity. Results: 44 patients received at least one dose of the study medication between November 2012 and February 2020. In this full analysis set (FAS) population, the median age was 38 (range 20-57), with 9 (20%) with seminoma, 23 (52%) non-seminoma and 12 (27%) of other histology. 31 (70%) patients had at least intermediate risk disease by IPFSG risk group criteria (n = 16, 36% intermediate risk, n = 6, 14% high risk, n = 9, 20% very high risk). 39 patients received 2 or more cycles of the treatment regimen and were deemed part of the subgroup of patients in the evaluable population. The ORR of the FAS population was 52.3% and 59.0% in the evaluable population. The metabolic response rate (MRR) was 52.3% in the FAS population and 59.0% in the evaluable population. The median radiological PFS in the FAS population was 17.0 months (95% CI, 5.7 months- not reached, NR) with a radiological PFS rate at two years of 38.7% (95% CI, 22.3%-54.9%). The median combined radiological or tumour marker PFS in the FAS population was 8.3 months (95% CI, 2.6 months-17.4 months) with a combined radiological or tumour marker PFS rate at two years of 28.9% (95% CI, 16.0%-43.1%). At a median follow-up of 26.8 months, the median OS in the FAS population was not reached (95% confidence interval [CI], 17.0 months-NR) with an OS rate at two years of 62.5% (95% CI, 46.1%-75.2%). Toxicity data and correlation between early metabolic response and outcomes will be presented at the meeting. Conclusions: The GAMMA chemotherapy regimen has demonstrated encouraging anti-tumor activity in relapsed GCT, despite recruiting a cohort of patients with relatively unfavorable outcomes. Clinical trial information: NCT01782339.

Abstract
Funding Acknowledgements Type of funding sources: None. OnBehalf Cardioovascular Analytics Group Background Medical research is critical to professional advancement, and mentoring is an important means of early research engagement in medical training. In contrast to international research collaborations, research mentoring programs are often locally limited. With the COVID-19 pandemic causing drifts to virtual classes and conferences, virtual international medical research mentoring may be viable. We hereby describe our experience with a virtual, international mentorship group for cardiovascular research. Methods Our virtual international research mentorship group has been running since 2015. The group focuses on risk stratification and outcomes research in cardiovascular medicine and epidemiology. Mentees from any country or region in all stages of medical careers are welcomed. Considering the increasing emphasis of contemporary research on multidisciplinary healthcare and translational research, our team also includes allied healthcare professionals or students, and graduates from natural sciences (Figure 1). With our members’ diverse backgrounds, we firmly adhere to the principle that all members must be given equal opportunities and treatment, regardless of their age, gender, race, nationality, sexual orientation, family background, and institution of study or practice. We make use of virtual platforms and multi-level mentoring (both senior and peer mentoring), and emphasize active participation, early leadership, open culture, accessible research support, and a distributed research workflow (i.e. an accessible-distributed model). Results Since establishment, our group has expanded to include 63 active members from 14 countries (Figure 2), leading a total of 109 peer-reviewed original studies and reviews published. We observed no significant difficulty in communication between team members, nor conflicts due to differences in nationality or ethnicity. Most studies involve cross-country and ethnicity collaborations, and inter-disciplinary and inter-regional knowledge exchanges are frequent. Multi-level mentoring ensured mentoring quality without compromising bonding and communication. Conclusion An accessible-distributed model of virtual international medical research collaboration and multi-level mentoring is viable, efficient, and caters to the needs of contemporary healthcare. We hope that others will build similar models and improve medical research mentoring globally.
