Projected increases of cancer-attributable health-care costs, accompanied by staff shortages, will impose future economic and operational challenges on national health-care systems. Herein, we highlight a series of clinical and health economic rationales in support of publicly funded clinical trial teams that conduct real-world dose-reduction trials aiming for adjustment of cancer drug label doses to reduce not only the financial burden on payers, but also the toxicity burden on patients.
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.
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.
Cyclin-dependent kinase (CDK) 4/6 inhibitors in combination with endocrine therapy have become the standard-of-care therapy for patients with advanced-stage hormone receptor-positive breast cancer. However, this success has created several challenges, such as the need to better understand resistance to these agents and develop novel therapies accordingly. Here, the authors provide an update on the clinical activity of the established CDK4/6 inhibitors along with a summary of ongoing research efforts attempting to address the new challenges created by the success of these agents.
p53, encoded by TP53, the commonest mutated gene in cancer, is an appealing target for systemic anticancer therapies including those designed to restore p53 function. Thus far, and despite promising preclinical data and several clinical trials, no p53-restoring systemic therapy has been approved for therapeutic use. Despite this limited success, several research efforts are ongoing. In this Review, the authors summarize the role of p53 in cancer with a focus on the complexity of p53 function and how this relates to clinical attempts to restore at least some of these functions.
Lung cancer is a disease typically associated with tobacco smoking; however, lung cancer in individuals who have never smoked (LCINS) is estimated to be the fifth most common cause of cancer-related deaths globally. Moreover, smoking rates are declining around the world and therefore LCINS is likely to increase as a proportion of all lung cancers over time. Thus, understanding the aetiology and features of LCINS is increasingly important. Herein, the authors review the emerging data on the epidemiology, clinical characteristics and molecular features of LCINS as well as the genetic and environmental risk factors for this disease. They also summarize the unique diagnostic and management paradigms of LCINS.
Myeloid-derived suppressor cells (MDSCs) are a heterogeneous population of myeloid cells that accumulate in the tumour microenvironment, where they exert various immunosuppressive mechanisms as well as a variety of other tumour-promoting effects. Herein, the authors provide an overview of MDSC generation and their accumulation in tumours, describe the interplay between MDSCs and various other cell types found in tumours, and review the mechanisms by which MDSCs promote tumour development and progression, metastasis, and resistance to treatment. They also discuss the effects of established treatment modalities on MDSCs as well as implications for the development of novel therapeutic strategies targeting these cells.
