Recent results from the phase III PHILA trial demonstrate a benefit in terms of progression-free survival derived from the addition of pyrotinib to first-line chemotherapy plus trastuzumab in patients with metastatic HER2-positive breast cancer. Dual HER2 blockade with pyrotinib and trastuzumab is an effective therapeutic strategy but might increase the risk of gastrointestinal toxicity; therefore, the risk-to-benefit ratio should be carefully evaluated.
Recent results from the FLAURA2 and MARIPOSA-2 trials underline the continued role of chemotherapy in the treatment of patients with EGFR-mutated non-small-cell lung cancer in the era of targeted therapies. Herein, we argue that the most appropriate and rational sequence and/or combination of therapies remains a matter of discussion.
Neoadjuvant cisplatin-based combination chemotherapy followed by radical cystectomy with pelvic lymphadenectomy is the current standard therapy for cisplatin-eligible patients with muscle-invasive bladder cancer (MIBC). A phase II trial testing treatment intensification by adding the immune-checkpoint inhibitor nivolumab to chemotherapy has yielded promising complete response rates, which suggests that bladder-preserving treatment could become attainable in selected patients. This trial heralds a new era in demonstrating the feasibility of bladder preservation for selected patients with MIBC.
PRO-TECT is a randomized trial that innovatively integrated financial toxicity screening into a pre-existing digital symptom-monitoring programme, enabling longitudinal detection of financial toxicity. Such a strategy provides an unobtrusive and cost-effective method for early detection and mitigation of financial toxicity by aligning the needs of patients and carers with the resources available in community clinical practices.
Epstein–Barr virus (EBV)-based biomarkers are used for nasopharyngeal carcinoma (NPC) screening in endemic regions. A recent prospective study describes the use of a new serological biomarker, antibodies targeting the EBV protein BNLF2b, for NPC screening in >20,000 participants. This biomarker yielded both higher sensitivity and specificity for NPC detection in the screening cohort compared with the conventionally used antibodies. Herein, we highlight the key findings of this study and discuss the implications of these results.
Following the recent FDA Accelerated Approval of enfortumab vedotin (EV) plus pembrolizumab for patients with advanced-stage urothelial carcinoma who are cisplatin-ineligible, herein we highlight key clinical outcomes with this combination based on results from Cohort K of the pivotal phase Ib/II EV-103 trial. We also discuss treatment sequencing, de-escalation strategies and toxicity management as EV–pembrolizumab becomes widely used in clinical practice.
Hotspot point mutations in IDH1 occur in the vast majority of adult grade 2–3 gliomas. The understanding of their role in tumour biology continues to evolve. Therapeutic targeting of mutant IDH1 with vorasidenib demonstrated highly encouraging efficacy and minimal toxicity in a recent, randomized phase III trial involving patients with low-grade gliomas.
A recent report from the ATLAS trial comparing different maintenance strategies following haematopoeitic stem cell transplantation for multiple myeloma provides an opportunity to explore various themes of critical appraisal, including end points, the equipoise of trial design, and the part censoring can play in the validity of results.
Planning for a pregnancy in patients receiving adjuvant endocrine therapy following a diagnosis of hormone receptor (HR)-positive early stage breast cancer is challenging. Recent data from the POSITIVE trial provide reassuring prospective evidence that a temporary interruption of endocrine therapy for women with HR-positive breast cancer who are trying to conceive can be considered safe in the short term for selected patients.
COSMIC-313 combines all of the approved drugs against actionable targets in renal cell carcinoma into one triplet regimen. Although this approach has greater clinical efficacy than one of the standard-of-care doublet therapies, toxicities can limit adequate drug administration and, thus, we argue that this regimen should not yet be adopted. We also discuss ongoing investigations of other triplet regimens.
Bispecific T cell engagers offer a novel treatment approach for patients with multiple myeloma, although mechanisms of resistance are largely unknown. Here, we discuss the implications of a recent report from Friedrich et al. that highlights the importance of pre-treatment T cell characteristics for a response to the T cell engager elranatamab and how these data might be used to inform future study and trial design.
Immune-checkpoint-inhibitor-associated myocarditis has a high fatality rate, warranting the development of more-effective treatment strategies. Herein, we discuss a recent report of a series of patients who were managed using a novel approach that involved personalized abatacept dosing, ruxolitinib and close respiratory monitoring, which was associated with low mortality.
Allele-specific inhibitors of KRASG12C are approved in non-small-cell lung cancer. Herein, we discuss recent results from the phase I/II KRYSTAL-1 trial of adagrasib alone and in combination with cetuximab in patients with KRASG12C-mutant metastatic colorectal cancer. The combination had promising efficacy and, if confirmed in later-phase trials, concomitant inhibition of EGFR and KRASG12C will present a new paradigm in precision oncology.
Neoadjuvant chemotherapy offers a pragmatic alternative to the difficulties associated with delivering timely adjuvant chemotherapy in rectal cancer. Enthusiasm for administering neoadjuvant therapy to all patients with locally advanced rectal cancer is based on data from several phase III trials. Data from the RAPIDO trial are a critical component of this evidence.
Plasma cell-free DNA analysis has emerged as a powerful liquid biopsy assay to assess circulating tumour DNA in response to cancer treatments. A new study shows that cell-free DNA can also inform on expansion kinetics and tumour-infiltration patterns in patients receiving chimeric antigen receptor T cells and, together with circulating tumour DNA, provides vivid prognostic insights into intratumoural dynamics.
Caring for individuals with thyroid nodules requires accurate estimation of their risk of thyroid cancer; however, available diagnostic tools offer only imprecise estimates. Novel biomarkers might help to clarify thyroid cancer risk and facilitate more-accurate diagnostic decision-making, although limitations in this area continue to exist.
New genetic analyses demonstrate that the presence of low-frequency subclonal populations, including high-risk subclones, at diagnosis in multiple myeloma can contribute to disease relapse and poor clinical outcomes. Thus, sensitive detection approaches are required to detect these subclones at diagnosis together with innovative treatment strategies to eradicate low-frequency, high-risk subclones and prevent them from becoming dominant.
