A phase III randomised study of first-line NUC-1031/cisplatin vs. gemcitabine/cisplatin in advanced biliary tract cancer.

Background And Aims: The previous first-line standard of care for advanced biliary tract cancer (aBTC), gemcitabine/cisplatin, had modest efficacy. NUC-1031 is a phosphoramidate modification of gemcitabine. We report final analyses of the NuTide:121 study, designed to compare the efficacy of NUC-1031/cisplatin to gemcitabine/cisplatin in aBTC.

A non-randomised open-label exploratory 'window of opportunity' study of TG02 treatment in patients with locally advanced primary and recurrent mutant colorectal cancer.

Background: TG02 is a peptide-based cancer vaccine eliciting immune responses to oncogenic codon 12/13 mutations. This phase 1 clinical trial (NCT02933944) assessed the safety and immunological efficacy of TG02 adjuvanted by GM-CSF in patients with -mutant colorectal cancer.

Methods: In the interval between completing CRT and pelvic exenteration, patients with resectable mutation-positive, locally advanced primary or current colorectal cancer, received 5-6 doses of TG02/GM-CSF.

Incidence, and maternal and neonatal outcomes following pregnancy-associated colorectal cancer: A population-based linked data study.

Aim: The study aimed to describe the incidence of pregnancy-associated colorectal cancer (PACRC) in New South Wales (NSW), Australia, and to examine the perinatal outcomes of women with PACRC and their babies.

Methods: A population-based cohort study was conducted using linked data from NSW. The study group comprised all women diagnosed with colorectal cancer during pregnancy (gestational CRC) or postpartum (postpartum CRC).

Cardiovascular disease and stroke following cancer and cancer treatment in older adults.

Background: Cancer survivors can be at risk of cardiovascular disease (CVD) because of either their malignancy or its treatment. Although studies linking cancer and CVD exist, few examine risk in older adults, the impact of cancer treatment, or the effect of aspirin on reducing risk in this cohort.

Methods: The authors conducted a secondary analysis of the Aspirin in Reducing Events in the Elderly (ASPREE) trial to investigate the impact of cancer and cancer treatment on a composite CVD end point comprising hospitalization for heart failure (HHF), myocardial infarction (MI), and stroke.

The INSIGHT study: a randomized, Phase III study of ripretinib versus sunitinib for advanced gastrointestinal stromal tumor with exon 11 + 17/18 mutations.

Somatic activating mutations drive most gastrointestinal stromal tumors (GISTs). Disease progression eventually develops with first-line imatinib, commonly due to secondary mutations, and different kinase inhibitors have various levels of treatment efficacy dependent on specific acquired resistance mutations. Ripretinib is a broad-spectrum switch-control KIT/PDGFRA tyrosine kinase inhibitor for patients with advanced GIST who received prior treatment with three or more kinase inhibitors, including imatinib.

Medication reuse programs: a narrative review of the literature.

A proportion of returned medications may potentially meet quality standards to be reused safely. In Australia, there is no regulatory guidance available to facilitate such medication reuse. This narrative review aimed to identify and review international literature describing medication reuse programs to provide insight into their implementation and potential barriers.

The impact of delayed diagnosis and treatment due to COVID-19 on Australian thyroid cancer patients: a qualitative interview study.

Objectives: The study aims to investigate the perceptions of patients with thyroid cancer on the potential impact of diagnosis and treatment delays during the COVID-19 pandemic.

Design: This study involved qualitative semi-structured telephone interviews. The interviews were transcribed verbatim, analysed using the thematic framework analysis method and reported using the Consolidated Criteria for Reporting Qualitative Research.

Cross-trial comparisons for the adjuvant treatment of MSI colorectal cancer: dare to dream the future scenarios.

The remarkable outcomes achieved with neoadjuvant checkpoint inhibitors for patients diagnosed with MSI colorectal cancer hold the potential to revolutionize the treatment landscape in this context. Specifically, the combination of nivolumab plus ipilimumab in colon cancer and dostarlimab in rectal cancer has led to an unprecedented rate of complete pathological and clinical responses. Notably, these responses have been further substantiated by the absence of relapses, with a 0% relapse rate observed during the first year of follow-up.

Efficacy of immune checkpoint inhibitors for metastatic colorectal cancer with microsatellite instability in second or latter line using synthetic control arms: A non-randomised evaluation.

Purpose: Immune checkpoint inhibitors (ICIs) appeared active in single-arm trials for patients with chemoresistant metastatic colorectal cancer (mCRC) harboring microsatellite instability (MSI). Given the paucity of randomised controlled trials (RCTs) in this setting, we evaluated the effect size of ICIs using intra-patients comparison and ARCAD database as historical controls.

Patients And Methods: Individual-patient data from NIPICOL and CheckMate 142 phase II trials that evaluated a combination of ICIs for MSI mCRC patients (N = 176) and from five non-ICI mCRC historical RCTs in second-line or latter (N = 4026) were analyzed.

Ripretinib versus sunitinib in gastrointestinal stromal tumor: ctDNA biomarker analysis of the phase 3 INTRIGUE trial.

INTRIGUE was an open-label, phase 3 study in adult patients with advanced gastrointestinal stromal tumor who had disease progression on or intolerance to imatinib and who were randomized to once-daily ripretinib 150 mg or sunitinib 50 mg. In the primary analysis, progression-free survival (PFS) with ripretinib was not superior to sunitinib. In clinical and nonclinical studies, ripretinib and sunitinib have demonstrated differential activity based on the exon location of KIT mutations.

Transverse Colon Primary Tumor Location as a Biomarker in Metastatic Colorectal Cancer: A Pooled Analysis of CCTG/AGITG CO.17 and CO.20 Randomized Clinical Trials.

Purpose: Sidedness is prognostic and predictive of anti-EGFR efficacy in metastatic colorectal cancer (mCRC). Transverse colon has been historically excluded from several analyses of sidedness and the optimal division between left- and right-sided colorectal cancer is unclear. We investigated transverse colon primary tumor location as a biomarker in mCRC.

Patient-reported outcomes and tolerability in patients receiving ripretinib versus sunitinib after treatment with imatinib in INTRIGUE, a phase 3, open-label study.

Purpose: In the INTRIGUE trial, ripretinib showed no significant difference versus sunitinib in progression-free survival for patients with advanced gastrointestinal stromal tumour (GIST) previously treated with imatinib. We compared the impact of these treatments on health-related quality of life (HRQoL).

Patients And Methods: Patients were randomised 1:1 to once-daily ripretinib 150 mg or once-daily sunitinib 50 mg (4 weeks on/2 weeks off).

Patterns of care for people with small cell lung cancer in Victoria, 2011-19: a retrospective, population-based registry data study.

Objectives: To report stage-specific patterns of treatment and the influence of management and treatment type on survival rates for people newly diagnosed with small cell lung cancer (SCLC).

Design: Cross-sectional patterns of care study; analysis of data prospectively collected for the Victorian Lung Cancer Registry (VLCR).

Setting, Participants: All people diagnosed with SCLC in Victoria during 1 April 2011 - 18 December 2019.

Multi-omic features of oesophageal adenocarcinoma in patients treated with preoperative neoadjuvant therapy.

Oesophageal adenocarcinoma is a poor prognosis cancer and the molecular features underpinning response to treatment remain unclear. We investigate whole genome, transcriptomic and methylation data from 115 oesophageal adenocarcinoma patients mostly from the DOCTOR phase II clinical trial (Australian New Zealand Clinical Trials Registry-ACTRN12609000665235), with exploratory analysis pre-specified in the study protocol of the trial. We report genomic features associated with poorer overall survival, such as the APOBEC mutational and RS3-like rearrangement signatures.

How therapeutic advances have transformed the medical landscape: a primer for clinicians.

Novel medicines are entering the market rapidly and are increasingly being used alone or in combination to treat illnesses of every sort. While transforming the lives of many patients, these new therapies have also forced us to reconsider the way we evaluate, use and fund medicines. This article offers a primer to help practitioners understand how the therapeutic landscape is changing and how this might impact the evidence generation, access to interventions, patient experience and quality of care.

Characteristics of patients diagnosed with pancreatic cancer who access palliative care: An observational study.

Purpose: Despite the benefits of palliative care (PC) in pancreatic cancer, little is known about patients who access PC. This observational study examines the characteristics of patients with pancreatic cancer at their first episode of PC.

Methods: First-time, specialist PC episodes captured through the Palliative Care Outcomes Collaboration (PCOC), in Victoria, Australia between 2014 and 2020, for pancreatic cancer, were identified.

Cancer Treatment Patterns and Factors Affecting Receipt of Treatment in Older Adults: Results from the ASPREE Cancer Treatment Substudy (ACTS).

Introduction: Cancer treatment planning in older adults is complex and requires careful balancing of survival, quality of life benefits, and risk of treatment-related morbidity and toxicity. As a result, treatment selection in this cohort tends to differ from that for younger patients. However, there are very few studies describing cancer treatment patterns in older cohorts.

Colon and rectal cancer treatment patterns and their associations with clinical, sociodemographic and lifestyle characteristics: analysis of the Australian 45 and Up Study cohort.

Background: Colorectal cancer is the third most diagnosed cancer globally and the second leading cause of cancer death. We examined colon and rectal cancer treatment patterns in Australia.

Methods: From cancer registry records, we identified 1,236 and 542 people with incident colon and rectal cancer, respectively, diagnosed during 2006-2013 in the 45 and Up Study cohort (267,357 participants).

Patient-reported outcomes in individuals with advanced gastrointestinal stromal tumor treated with ripretinib in the fourth-line setting: analysis from the phase 3 INVICTUS trial.

Background: Ripretinib is a novel switch-control kinase inhibitor that inhibits KIT and PDGFRA signaling. In the INVICTUS phase 3 trial, ripretinib increased median progression-free survival and prolonged overall survival vs. placebo in ≥ fourth-line advanced GIST.

Updated cost-effectiveness analysis of lung cancer screening for Australia, capturing differences in the health economic impact of NELSON and NLST outcomes.

Background: A national, lung cancer screening programme is under consideration in Australia, and we assessed cost-effectiveness using updated data and assumptions.

Methods: We estimated the cost-effectiveness of lung screening by applying screening parameters and outcomes from either the National Lung Screening Trial (NLST) or the NEderlands-Leuvens Longkanker Screenings ONderzoek (NELSON) to Australian data on lung cancer risk, mortality, health-system costs, and smoking trends using a deterministic, multi-cohort model. Incremental cost-effectiveness ratios (ICERs) were calculated for a lifetime horizon.

Monitoring quality of care in hepatocellular carcinoma: A modified Delphi consensus.

Although there are several established international guidelines on the management of hepatocellular carcinoma (HCC), there is limited information detailing specific indicators of good quality care. The aim of this study was to develop a core set of quality indicators (QIs) to underpin the management of HCC. We undertook a modified, two-round, Delphi consensus study comprising a working group and experts involved in the management of HCC as well as consumer representatives.
