Purpose of review: The evidence regarding the effectiveness of interventions aiming to improve ACP uptake appears mixed. The purpose of this scoping review is to summarize findings from recent RCTs assessing the efficacy of interventions designed to increase ACP uptake in cancer care.

Recent findings: The PubMed database was searched for studies published between 2021 and 2023. Ten RCTs were identified that evaluated a wide range of interventions aimed at encouraging or facilitating ACP communication among patients with advanced cancer, caregivers, and HCPs. Three RCTs developed ACP facilitation tools for patients and sometimes caregivers. Six RCTs involved integrating trained ACP facilitators into patient care, and one RCT used nudges to encourage oncologists trained in ACP discussions to initiate discussions with patients at highest risk of short-term mortality. Most of the reviewed interventions were based on previously tested intervention approaches or tools.

Summary: The key effects identified in this review are the facilitation of ACP discussions among patients, caregivers, and HCPs, and the documentation of patient preferences in the medical record. The direct involvement of facilitators in ACP document drafting and inclusion in patient files, as well as interventions prompting end-of-life discussions, contributed to this effect.

Purpose of review: Symptom burden of cancer diagnosis and treatment has led adolescents and young adult cancer patients (AYAC) and survivors to seek different self-management strategies including integrative oncology (IO) modalities. IO holds great promise to improve survivorship issues in adolescents and young adult (AYA) cancer survivors. This review aims to encompass the current evidence of IO modalities and to analyze the efficacy of IO for managing survivorship issues among AYA cancer patients and survivors.

Recent findings: Nineteen randomized controlled trials included in this review evaluated mind and body modalities including both physical and psychological (74%) and psychological only (26%) modalities. Most assessed IO modalities were physical activity (PA) (37%) and structured exercise (10%). Most effective IO modalities found were PA, massage, mindfulness-based stress reduction (MBSR) and light therapy for treating AYA symptom burden. The Cochrane risk of bias (RoB-2) concluded 21% studies had high risk, 58% possessed some concerns and 21% had low risk.

Summary: Although evidence has shown that a number of IO modalities may improve survivorship among AYA cancer survivors, more rigorous study designs are needed in order for these modalities to be routinely recommended for use in clinical practice.

Purpose of review: Supportive care in oncology has evolved alongside effective anticancer treatments since the 1960s, beginning with the advent of chemotherapy for acute leukemia. It was initially focused on managing treatment-induced complications, and expanded to address broader aspects of patient well being; the scope of supportive care needs to be periodically re-assessed.

Recent findings: Early palliative care interventions, and more recently advance care planning emerged as vital components, improving patient outcomes and quality of life. Despite barriers, such as prognostic uncertainty, these approaches have demonstrated significant benefits for patients with advanced disease. Additionally, the management of cancer survivors requires ongoing medical surveillance and psycho-social support. In the last years, integrative medicine has also emerged as a complementary approach to address survivors' holistic needs.

Summary: A proposed stratified model of supportive care emphasizes interventions based on patients' prognosis, with interdisciplinary collaboration ensuring comprehensive care across all stages of the cancer journey. This model provides a framework for the development of integrated supportive care units.

Purpose of review: This article discusses the evolving approaches to desmoid tumors management, shedding light on recent developments.

Recent findings: Active surveillance has become the primary approach for managing primary peripheral desmoid tumors. This strategy was initially based on evidence from retrospective studies. Roughly 50% of cases managed with active surveillance show spontaneous stabilization or regression. Recent prospective trials conducted in Italy, The Netherlands, and France (2022-2023) confirm the efficacy of active surveillance, revealing 3-year progression-free survival rates ranging from 53.4 to 58%. For the patients under active surveillance, decisions regarding treatment are based on significant tumor growth or progressive symptoms. Moreover, three contemporary randomized trials investigated medical treatments for progressive or recurrent desmoid tumors. Sorafenib, pazopanib, and nirogacestat demonstrated clinical activity, as evidenced by favorable progression-free survival and objective response rates.

Summary: Active surveillance has solidified its position as the primary management approach for desmoid tumors, validated by three robust prospective studies. Three recent randomized trials explored medical treatment for progressive or recurrent desmoid tumors, revealing promising clinical activities.

Purpose of review: This review is timely and relevant due to the increasing recognition of the significance of the fibroblast growth factor receptor (FGFR) family in cancer biology. Understanding the role of FGFRs and their dysregulation in various cancers is crucial for developing targeted therapies and improving patient outcomes.

Recent findings: The review highlights the importance of the FGFR family in cellular processes such as growth, proliferation, and survival. It discusses how abnormalities in FGFR2, including overexpression, gene amplification, and other genetic alterations, contribute to cancer progression, particularly in gastro-intestinal cancers. The paper also emphasizes the promising results of FGFR-targeted therapies, especially tyrosine kinase inhibitors, in certain cancers such as cholangiocarcinoma and oesophagogastric cancers.

Summary: The findings underscore the potential of FGFR-targeted therapies in treating cancers with FGFR dysregulation. However, the review also addresses the challenges associated with these therapies, including toxicities and mechanisms of resistance. Understanding these complexities is essential for optimizing the efficacy of FGFR-targeted treatments and improving patient outcomes in clinical practice and research efforts.

Purpose of review: This review critically evaluates the evolution and current status of human epidermal growth factor receptor 2 (HER2)-directed therapies in upper gastrointestinal (GI) malignancies, a timely and relevant inquiry given the dynamic shifts in therapeutic strategies over the past decade. Initial enthusiasm following the Trastuzumab for Gastric Cancer (ToGA) study's demonstration of trastuzumab's efficacy, however, encountered hurdles due to subsequent trials showing limited progress, underscoring the necessity for a reevaluation of therapeutic approaches and the exploration of novel agents.

Recent findings: The review highlights significant breakthroughs in the form of immune checkpoint inhibitors and innovative therapeutic technologies, which have redefined treatment paradigms and shown promising efficacy in HER2-positive cases. Emerging treatments such as trastuzumab deruxtecan (T-DXd), zanidatamab and evorpacept further illustrate the ongoing efforts to leverage unique mechanisms of action for improved HER2-positive antitumor activity.

Summary: The advancements in HER2-directed therapies underscore a pivotal era in the management of upper GI malignancies. These developments not only reflect the profound impact of integrating novel therapeutic combinations but also highlight the critical role of ongoing research in overcoming resistance mechanisms and tailoring treatment to individual disease profiles.

Purpose of review: Claudins, components of tight cell junctions in epithelial and endothelial cells, have emerged as a therapeutic target in gastrointestinal (GI) malignancies, particularly claudin 18.2 (CLDN18.2).

Recent findings: Zolbetuximab, a chimeric anti-CLDN18.2 monoclonal antibody (mAb), is currently under FDA review and may emerge as the first claudin targeted therapy approved. Phase 3 trials show that zolbetuximab in combination with front-line fluoropyrimidine plus oxaliplatin improves survival in advanced CLDN18.2 positive (≥75% of tumor cells) gastric adenocarcinoma (GAC) patients. Many other therapies (mAbs; CART; bispecific; ADCs) are under investigation.

Summary: CLDN18.2 will be an important target in GAC. Early understanding of how to target CLDN18.2 based on the level of expression (high, moderate, low) will be the key to success in this area. Studying these as separate entities should be considered. Resistance patterns, loss of CLDN18.2 expression, role in the refractory setting, and if any role in localized disease are questions that remain. Other targets for claudin that target claudin six and four are under investigation. Their role in GI malignancies will soon be further clarified.

Purpose of review: There is a critical need for timely and accurate decisions in breast cancer management. This narrative review aims to clarify the potential role of novel PET tracers in optimizing treatment strategies for different breast cancer subtypes.

Recent findings: 2-deoxy-2-[18F]-fluoro-D-glucose PET/computed tomography (FDG PET/CT) has a pivotal role in response assessment in metastatic breast cancer, despite its limitations in certain histological and molecular subtypes. Further PET radiopharmaceuticals have been proposed to address these clinical needing.

Summary: FES PET/CT demonstrates its usefulness in assessing ER expression and predicting response to therapy in luminal breast cancer, with implications for treatment optimization and monitoring. In HER2-positive and HER2-low breast cancer, HER2-targeted PET tracers show potential in assessing HER2 status, while their accuracy in predicting response to targeted therapies is still debated. PARP-targeted PET imaging holds potential for selecting patients for PARP inhibitors treatments, particularly in triple-negative breast cancer (TNBC), where imaging tools are crucial due to the absence of specific targets. Immunotherapy and antibody-drug conjugates (ADCs) are emerging treatment options for TNBC, and PET imaging targeting immune checkpoints could aid in treatment selection and response monitoring. The dynamic role of PET/CT imaging in tailoring breast cancer treatments requires further multidisciplinary research to validate the clinical utility of targeted tracers.

Purpose of review: Use of adjuvant chemotherapy significantly reduced the risk of recurrence and improved overall survival (OS) in patients with early-stage breast cancer. However few data are available on efficacy of different adjuvant chemotherapy regimens and schedules in patients with hormone receptor positive/HER2-negative (HR+/HER2-) breast cancer. We aim to summarize the available evidence on efficacy of adjuvant anthracycline-based chemotherapy and of the dose-dense schedule in this population. Moreover, current controversies in the management of patients with early-stage HR+/HER2- breast cancer are discussed.

Recent findings: Patient-level meta-analysis evaluating the role of the addition of anthracycline to taxane-based chemotherapy showed that recurrence rate was 14% lower [relative risk (RR) 0.86, P = 0.0004] among patients receiving anthracycline-based treatment.Patient-level meta-analysis evaluating the role of different schedules of chemotherapy administration showed that the use of adjuvant dose-dense chemotherapy is associated with significant reduction in breast cancer recurrences and breast cancer mortality. Less evidence is available in the neoadjuvant setting.

Summary: For patients with high-risk HR+/HER2- breast cancer, (neo) adjuvant anthracycline and taxane-based chemotherapy, and a dose-dense regimen should still be considered the standard of care. However, in patients with intermediate-low risk breast cancer anthracycline-free regimens could be considered an option of treatment.

Purpose of review: There is still a need of biomarkers in the induction and neoadjuvant settings for squamous cell carcinoma of the head and neck (SCCHN). The objective of this concise review article is to give an overview on both predictive and prognostic biomarkers potentially useful for the management of SCCHN.

Recent findings: Human papilloma virus (HPV) positivity translated by the presence of the protein indicator p16 is synonymous of favorable prognosis SCCHN. However, there is some disparity for disease evolution among p16 positive SCCHN. A lack of correlation between immunohistochemistry (IHC) and precise quantification of active epidermal growth factor receptors (EGFRs) may explain the absence of link between EGFR expression performed by IHC and response to EGFR targeting therapies reported in SCCHN. Circulating tumor cells (CTCs) have the property to share the main somatic mutations and genetic rearrangements with the primary tumors. A particular potential interest lies on the possibility to predict patient outcome based on a single-CTC analysis.

Summary: This short review indicates that key biological marker reflecting disease outcome is not yet emerging for a clinical use in SCCHN. Hopes can be put into the so-called liquid biopsies incorporating circulating tumor cells and circulating tumor DNA.
