Immune checkpoint inhibitors (ICIs) have substantially advanced the treatment landscape for a wide variety of malignancies. Older adults represent a large and rapidly growing demographic, among whom ICIs are widely prescribed. Management of ICI-associated toxicity among older adults, particularly in the presence of frailty and comorbidity, poses unique challenges. In this Policy Review, developed by the International Society of Geriatric Oncology (SIOG), we offer an evidence-based framework for health-care providers, caregivers, and policy makers for treating older adults with ICIs, focusing on unique considerations for this population that are not adequately addressed by existing guidelines, and expanding them to encompass geriatric oncology principles.

The KEYNOTE-564 trial showed that adjuvant immune checkpoint inhibitor (ICI) therapy with pembrolizumab, a PD-1 antibody, significantly improved disease-free survival (DFS) and overall (OS) survival in localised clear-cell renal cell carcinoma (RCC) with a high risk of relapse. The TiNivo and CONTACT-03 trials have reported results for subsequent therapy after progression on ICI therapy in the metastatic setting. The European Association of Urology (EAU) RCC guidelines panel reassessed the new trial results to update recommendations for adjuvant therapy and post-adjuvant therapy. Adjuvant pembrolizumab significantly improved OS (hazard ratio 0.62, 95% confidence interval 0.44-0.87; p = 0.005). Recent trials of subsequent ICI after recurrence on ICI in the metastatic setting do not support ICI monotherapy or combination therapy in patients with recurrence on or after adjuvant ICI therapy. There are no prospective trial results for treatment after adjuvant pembrolizumab failure. On the basis of the recent results, the EAU RCC guidelines panel has updated the recommendation for adjuvant therapy and now issues a strong recommendation for adjuvant pembrolizumab. ICI monotherapy or combination therapy is not recommended in patients with recurrence during or shortly after adjuvant pembrolizumab. PATIENT SUMMARY: Treatment with an immunotherapy drug called pembrolizumab after surgery in patients with intermediate-risk or high-risk kidney cancer delays the time to recurrence of cancer and prolongs survival. Therefore, pembrolizumab after surgery is strongly recommended for these patients. However, a significant proportion of patients have life-changing or serious side effects and these must be discussed.

The NCCN Guidelines for the Management of Immunotherapy-Related Toxicities are intended to provide oncology practitioners with guidance on how to manage the wide-ranging and potentially fatal toxicities that may occur with cancer immunotherapy. The guidelines address immune-related adverse events related to immune checkpoint inhibitors, CAR T-cell therapies, and lymphocyte engagers (which include T-cell-engaging bispecific antibodies). These NCCN Guidelines Insights highlight recent guideline updates pertaining to the management of emerging toxicities related to cancer immunotherapy.

This good practice paper (GPP) is intended to support clinicians in assessing patient fitness for bleomycin and in management of bleomycin pulmonary toxicity (BPT) where it occurs. Bleomycin, originally developed as an antibiotic in the 1960s, has been a cornerstone of therapy for classical Hodgkin lymphoma (CHL) since results of its use in combination with doxorubicin, vincristine and dacarbazine (ABVD) were first published by Bonadonna et al in 1975 1. The same author recognised high rates of respiratory morbidity in these patients 2, and bleomycin-;related pulmonary toxicity (BPT) is now a well-;recognised and feared complication with its use. ABVD and BEACOPP/ BEACOPDac (bleomycin, cyclophosphamide, etoposide, doxorubicin, vincristine and prednisolone, with procarbazine or dacarbazine) are standard first-;line treatments in CHL patients, but considerable variation remains in assessing patient fitness for bleomycin both clinically and with respiratory investigations. A recent survey of British haematologists regularly using bleomycin revealed that 87.5% have no local protocols for assessing patients in an evidence-;based fashion, with wide variations in practice captured in the same survey (personal data). A working group was established and a literature review undertaken with the goal of presenting practical recommendations for clinicians regarding bleomycin use based on available evidence and expert opinion.

Extravasation (EV), or the leakage of anticancer drugs into perivascular and subcutaneous tissues during intravenous administration, can cause serious conditions that may require surgical intervention. Therefore, updated guidelines for EV based on systematic review are needed. Additionally, classifications for anticancer drugs that cause EV are not standardized across the current guidelines, and some novel drugs have not been classified. Therefore, this study aimed to formulate guidelines using evidence-based information for shared decision making on prevention, early detection, treatment, and care for EV in Japan and provide additional classification for tissue injury based on systematic review.

Global prevalence rates for transgender individuals vary with estimates ranging from 0.3% to 1%, translating to a potential global population of 24.3 million to 81 million. It is estimated that one in two people will develop cancer in their lifetime. Gender-affirming hormone therapy (GAHT) is a common medical intervention for transgender and non-binary individuals. GAHT requires careful consideration for concurrent medical care due to potential drug interactions and physiological changes. A multi-disciplinary team with expertise in transgender health, oncology and pharmacy met to develop a document summarizing current knowledge on the topic for practical use. The team included trans and non-binary authors who shaped the document's language and focus. The document gives a status update on the current understanding of GAHT and how this may intersect with the safe prescribing of systemic anti-cancer therapies (SACT). The document underwent multiple review stages including internal review, review by the British Oncology Pharmacy Association (BOPA) EDI Subcommittee and, finally, BOPA Executive Committee review and final approval. Key recommendations of this document include the use of inclusive and effective communication, vigilant monitoring of kidney function and cardiovascular health, and considerations for hormone receptor-positive cancers. The document also recognizes the multidisciplinary nature of transgender healthcare and where this relates to social prescribing.

A MASCC/ISOO Clinical Practice Statement (CPS) is aimed at generating a concise tool for clinicians that concentrates practical information needed for the management of oral complications of cancer patients. This CPS is focused on the management of oral complications of targeted therapy.

To provide guidance, via multidisciplinary consensus statements, on the safety interactions between systemic anticancer agents (such as radiosensitizing chemotherapy, immunotherapy, targeted therapy, and peptide receptor radionuclide therapy) and transarterial radioembolization (TARE) with yttrium-90 (90Y)-labeled microspheres in the treatment of primary and metastatic liver malignancies.

Accurate assessment of GFR is crucial to guiding drug eligibility, dosing of systemic therapy, and minimizing the risks of both undertreatment and toxicity in patients with cancer. Up to 32% of patients with cancer have baseline CKD, and both malignancy and treatment may cause kidney injury and subsequent CKD. To date, there has been lack of guidance to standardize approaches to GFR estimation in the cancer population. In this two-part statement from the American Society of Onco-Nephrology, we present key messages for estimation of GFR in patients with cancer, including the choice of GFR estimating equation, use of race and body surface area adjustment, and anticancer drug dose-adjustment in the setting of CKD. These key messages are based on a systematic review of studies assessing GFR estimating equations using serum creatinine and cystatin C in patients with cancer, against a measured GFR comparator. The preponderance of current data involving validated GFR estimating equations involves the CKD Epidemiology Collaboration (CKD-EPI) equations, with 2508 patients in whom CKD-EPI using serum creatinine and cystatin C was assessed (eight studies) and 15,349 in whom CKD-EPI with serum creatinine was assessed (22 studies). The former may have improved performance metrics and be less susceptible to shortfalls of eGFR using serum creatinine alone. Since included studies were moderate quality or lower, the American Society of Onco-Nephrology Position Committee rated the certainty of evidence as low. Additional studies are needed to assess the accuracy of other validated eGFR equations in patients with cancer. Given the importance of accurate and timely eGFR assessment, we advocate for the use of validated GFR estimating equations incorporating both serum creatinine and cystatin C in patients with cancer. Measurement of GFR via exogenous filtration markers should be considered in patients with cancer for whom eGFR results in borderline eligibility for therapies or clinical trials.

Multiple myeloma remains an incurable disease, despite the development of numerous drug classes and combinations that have contributed to improved overall survival. Immunotherapies directed against cancer cell-surface antigens, such as chimeric antigen receptor (CAR) T-cell therapy and T-cell-redirecting bispecific antibodies, have recently received regulatory approvals and shown unprecedented efficacy. However, these immunotherapies have unique mechanisms of action and toxicities that are different to previous treatments for myeloma, so experiences from clinical trials and early access programmes are essential for providing specific recommendations for management of patients, especially as these agents become available across many parts of the world. Here, we provide expert consensus clinical practice guidelines for the use of bispecific antibodies for the treatment of myeloma. The International Myeloma Working Group is also involved in the collection of prospective real-time data of patients treated with such immunotherapies, with the aim of learning continuously and adapting clinical practices to optimise the management of patients receiving immunotherapies.

The management of young patients with cancer presents several unique challenges. In general, these patients are ill prepared for the diagnosis and the impact on their fertility. With the improved survival for all tumour types and stages, the need for adequate fertility counselling and a multidisciplinary approach in the reproductive care of these patients is paramount. Recent advances in cryopreservation techniques allow for the banking of spermatozoa, oocytes, embryos and ovarian tissue without compromising survival. This Canadian Fertility and Andrology Society (CFAS) guideline outlines the current understanding of social and medical issues associated with oncofertility, and the medical and surgical technologies available to optimize future fertility.

The development of the immune checkpoint inhibitors (ICI) is one of the most remarkable achievements in cancer therapy in recent years. However, their exponential use has led to an increase in immune-related adverse events (irAEs). Gastrointestinal and liver events encompass hepatitis, colitis and upper digestive tract symptoms accounting for the most common irAEs, with incidence rates varying from 2% to 40%, the latter in patients undergoing combined ICIs therapy. Based on the current scientific evidence derived from both randomized clinical trials and real-world studies, this statement document provides recommendations on the diagnosis, treatment and prognosis of the gastrointestinal and hepatic ICI-induced adverse events.

Our goal was to identify new anticancer agents approved by the US Food and Drug Administration (FDA) and the European Medical Agency (EMA) since the 2016 MASCC/ESMO antiemetic update and classify their emetic potential.

Thrombocytopenia is a common adverse effect of chemotherapy. The development of chemotherapy-induced thrombocytopenia (CIT) is influenced by cancer type and therapy, occurring in approximately one-third of patients with a solid tumor diagnosis and half of all patients with a hematologic malignancy. CIT may complicate the administration of chemotherapy, leading to therapeutic delays or dose reductions. This guidance document, presented by the International Society on Thrombosis and Haemostasis (ISTH) Subcommittee on Hemostasis and Malignancy, provides a comprehensive summary of the evidence and offers direction on the use of thrombopoietin receptor agonists (TPO-RAs) in various settings of CIT, including solid tumors, acute myeloid leukemia, stem cell transplant, and lymphoma. Studies have shown that TPO-RAs can improve platelet counts in CIT, but the clinical benefits of TPO-RA in terms of reducing bleeding, limiting platelet transfusion, avoiding chemotherapy delay, or dose reduction are uncertain. Further research is needed to optimize the selection of appropriate indications and study design to manage thrombocytopenia following chemotherapy.

This clinical practice guideline update provides recommendations for treating breakthrough chemotherapy-induced nausea and vomiting (CINV) and preventing refractory CINV in pediatric patients. Two systematic reviews of randomized controlled trials in adult and pediatric patients informed the recommendations. In patients with breakthrough CINV, escalation of antiemetic agents to those recommended for chemotherapy of the next higher level of emetogenic risk is strongly recommended. A similar recommendation to escalate therapy is made to prevent refractory CINV in patients who did not experience complete breakthrough CINV control and are receiving minimally or low emetogenic chemotherapy. A strong recommendation to use antiemetic agents that controlled breakthrough CINV for the prevention of refractory CINV is also made.

This clinical practice guideline provides recommendations for preventing acute and delayed phase chemotherapy-induced nausea and vomiting (CINV) in pediatric patients. The recommendations are based on two systematic reviews of randomized controlled trials evaluating interventions to prevent (1) acute phase CINV and (2) delayed phase CINV. Recommendations for acute phase and delayed phase CINV prophylaxis are made for patients receiving chemotherapy of varying emetogenicity, as well as for patients not able to receive dexamethasone or a neurokinin-1 receptor antagonist. Evidence gaps, including antiemetic safety and optimal dosing, were identified.

Immunotherapy has transformed the treatment paradigm of several cancers. Hospital-at-home (HAH) care is an innovative healthcare model in which treatments are delivered at home under the supervision of a hospital, which likely applies to cancer immunotherapy. For this home-care option, official treatment guidelines are still lacking. We therefore sought to create guidance and recommendations on how to administer immune response checkpoint inhibitor therapies and other monoclonal antibodies used in cancer treatment in the context of HAH setting.

Coronary artery disease (CAD) is a concerning late outcome for cancer survivors. However, uniform surveillance guidelines are lacking.

ASCO Rapid Recommendations Updates highlight revisions to select ASCO guideline recommendations as a response to the emergence of new and practice-changing data. The rapid updates are supported by an evidence review and follow the guideline development processes outlined in the ASCO Guideline Methodology Manual. The goal of these articles is to disseminate updated recommendations, in a timely manner, to better inform health practitioners and the public on the best available cancer care options.
