Purpose of review: In this review, we discuss which patients with metastatic clear cell renal cell carcinoma (mRCC) may be most suitable for frontline tyrosine kinase inhibitor (TKI) monotherapy, a treatment option supported by emerging long-term efficacy data including overall survival and quality of life. We specifically focus on tivozanib, a potent and selective inhibitor of vascular endothelial growth factor receptor, which has comparable efficacy to other single-agent TKIs in frontline treatment for mRCC while exhibiting fewer off-target side effects.

Recent findings: Combination therapy with TKIs and checkpoint inhibitors (CPIs) and CPI/CPI combination therapies, as well as TKI monotherapy are recommended frontline treatment options for mRCC. Treatment decisions are complex and based on several factors, including the patient's International Metastatic RCC Database Consortium risk status, age, comorbidities, and personal preferences related to response, tolerability, and quality of life. TKIs not only serve as backbone of most combination therapies for mRCC, but also remain a viable monotherapy option in the first-line setting for patients in favorable risk groups and those with contraindications to CPI combination therapies. Given that overall survival benefits have not yet been confirmed for CPI-containing combination regimens in favorable risk patients, we argue that frontline single-agent TKI treatment remains a standard of care option for these patients. This is supported by treatment guidelines, even in the era of TKI/CPI combination therapies.

Purpose of review: This review examines contemporary strategies for managing brain metastases (BM) from common cancers such as lung, breast, and melanoma. We evaluate the efficacy and applicability of targeted therapies and immunotherapies, exploring their potential to cross the blood-brain barrier and improve patient outcomes.

Recent findings: Recent studies have shown that tyrosine kinase inhibitors, immune checkpoint inhibitors, and ADCs effectively treat BM. These treatments can overcome the challenges posed by the blood-brain barrier and improve therapeutic outcomes. ADCs are promising because they can deliver cytotoxic agents directly to tumor cells, which reduces systemic toxicity and increases drug delivery efficiency to the brain. Personalized medicine is becoming increasingly significant in treatment decisions, with biomarkers playing an essential role. Advances in molecular genetics and drug development have led to more refined treatments, emphasizing the precision medicine framework. The management of BM is evolving, driven by drug efficacy, resistance mechanisms, and the need for personalized medicine. Integrating ADCs into treatment regimens represents a significant advancement in targeting metastatic brain tumors. Despite these advances, BM management still presents considerable challenges, requiring ongoing research and multi-institutional trials to optimize therapeutic strategies. This review outlines the current state and future directions in treating BM, highlighting the critical need for continued innovation and comprehensive clinical evaluations to improve survival rates and quality of life for affected patients.

Purpose of review: There has been controversy in the management of gastroesophageal (GE) junction cancers with pre-operative chemoradiation and peri-operative chemotherapy as accepted practices. We aim to assess and compare the defining trials establishing current standards of care and discuss future directions seeking to further improve patient-centered outcomes in GE junction cancers.

Recent findings: Over the last two decades, several large Phase III randomized trials have been conducted including GE junction cancers, showing superiority of 1) pre-operative chemoradiation over surgery (CROSS) and 2) peri-operative chemotherapy with FLOT over CROSS without radiotherapy (FLOT 4). While NEO-Aegis suggested equipoise between the CROSS vs. peri-operative chemotherapy, the recently presented ESOPEC trial demonstrated superiority of peri-operative FLOT versus CROSS in esophagus and GE junction adenocarcinomas. Based on the ESOPEC trial, peri-operative chemotherapy with FLOT appears to be a preferred regimen for patients with resectable GE junction adenocarcinomas in patients able to receive FLOT. There is evidence in support of other practices, such as induction chemotherapy, pre-operative chemoradiation, definitive chemoradiation for those not fitting ESOPEC criteria. Chemoradiation ± chemotherapy with non-operative intent represents a promising strategy for patients seeking organ preservation, and ongoing studies will better define its feasibility and long-term outcomes.

Purpose of review: The purpose of this review is to provide an overview of the practical applications of comprehensive cancer rehabilitation services through telemedicine.

Recent findings: Telemedicine has been shown to be an effective platform leading to positive outcomes and high patient/provider satisfaction for several forms of skilled therapy and cancer physiatry visits. Several survivorship resources are also available through telemedicine in recent years. Telemedicine can increase accessibility to geographically sequestered services including cancer physiatry, skilled therapy and survivorship resources. In certain situations and for specific services, telemedicine can be effective, however, in other situations such as the evaluation of new neurologic deficits or when providing manual therapies, in-person visits should take precedence.

Purpose of review: This review aims to provide an update on current knowledge regarding paediatric acute lymphoblastic leukaemia (ALL), focusing on recent advancements in diagnosis and treatment, as well as future directions in the field.

Recent findings: ALL is the most frequently diagnosed paediatric malignancy, with advances leading to a 90% survival rate. The heterogeneity of childhood ALL requires a precise diagnostic algorithm incorporating morphological, immunophenotypic, and cytogenetic analyses. Research is exploring next-generation sequencing and artificial intelligence-aided techniques for future diagnostic approaches. Despite these advancements, global disparities in healthcare access hinder prompt diagnosis and management. The pathophysiology of ALL involves chromosomal and genetic alterations which disrupt cell-cycle regulation and result in uncontrolled lymphoblast proliferation. Environmental factors also contribute to leukaemogenesis. Risk-stratification based on genetic subtypes has significant implications for risk-based therapy. Chemotherapy is administered in three phases: induction, consolidation, and maintenance, with prophylactic intrathecal chemotherapy considered essential. For high-risk, refractory, or relapsed ALL, haematopoietic stem cell transplantation and novel therapies such as tyrosine kinase inhibitors, chimeric antigen receptor T-cell therapy, and blinatumomab immunotherapy, have improved outcomes. Ongoing clinical trials aim to further improve treatment efficacy, reduce toxicity, and increase survival. Although prevention strategies for ALL exist at three levels, the supporting evidence remains limited, highlighting a need for further research. Continued research and clinical trials are essential to addressing the gaps treatment efficacy and prevention strategies. Efforts to improve global healthcare access and integrate novel diagnostic and therapeutic approaches are crucial for advancing outcomes for paediatric patients with ALL.

Purpose of review: Adolescent and young adult (AYA) breast cancer survivors face a significant risk of infertility due to the gonadotoxic effects of (neo)adjuvant therapy, which complicates their ability to conceive post-treatment. While (neo)adjuvant therapy primarily aims to improve recurrence-free and overall survival, fertility preservation strategies should also be considered for young patients. This narrative review explores recent advancements in fertility preservation techniques, such as oocyte, embryo, and ovarian tissue cryopreservation, and evaluates the feasibility of modifying breast cancer (neo)adjuvant therapy to preserve fertility without compromising survival outcomes.

Recent findings: Our review highlights that clinical trials with co-primary endpoints of oncological safety and fertility preservation are limited, and substituting standard treatment regimens solely for fertility preservation is currently not recommended. Nevertheless, new clinical studies have emerged that either exclude highly ovarian-toxic agents, such as cyclophosphamide, or omit adjuvant therapy altogether, even if fertility preservation is not their primary endpoint. Unfortunately, many of these trials have not evaluated ovarian toxicity. Notably, since 2020, major oncology organizations, including the American Society of Clinical Oncology (ASCO), the European Society of Medical Oncology (ESMO) have advocated for the routine assessment of ovarian toxicity in all clinical trials. The review underscores the importance of incorporating ovarian toxicity as a standard endpoint in future trials involving premenopausal breast cancer patients to identify treatment regimens that can effectively balance fertility preservation with treatment efficacy.

Purpose of review: This study aims to identify health inequities related to the medical treatment and supportive care of patients with advanced/metastatic cancer and recommend solutions to promote health equity.

Recent findings: Despite robust strides in the development of therapeutic strategies for advanced and metastatic cancer, significant disparities in treatment access and implementation exist. Race, socioeconomic status, gender, and geography represent just a few of the individual-level factors which contribute to challenges in treatment administration, thorough evaluation of germline genetics and tumor genomics, and quality palliative and end-of-life care. Given the increasing complexity of cancer treatments and our enhanced understanding of tumor biology, efforts to uniformly provide equitable and high-level care to all patients are needed. In this review we will discuss factors that contribute to health inequities in patients with advanced and metastatic cancer diagnoses, highlighting opportunities for intervention, ongoing challenges in change implementation, and national and international society recommendations to eliminate disparities. Acknowledging existing inequities and engaging in multilevel discourse with key stakeholders is needed to optimize care practices to the benefit of all patients.

Purpose of review: Gynecological malignancies are prevalent in females, and this population is likely to experience symptoms of pelvic floor disorders and sexual dysfunction. Non-surgical, non-pharmaceutical conservative therapies, namely pelvic floor muscle (PFM) therapies and education-based interventions, could be beneficial for this population. The purpose of this systematic review was to examine the evidence regarding their effectiveness on bladder, bowel, vaginal, sexual, psychological function, quality of life, and PFM function in gynecological cancer populations.

Recent findings: Six databases were searched to identify studies employing any interventional study design, except case studies, to investigate the effect of PFM therapies, education-based interventions, or combined therapies on any outcome of interest. The search yielded 4467 results, from which 20 studies were included. Of these, 11 (55%) were RCTs, two (10%) were non-RCTs with two groups, and seven (35%) were non-RCTs with a single group. Findings suggest that combined (multimodal) therapies, specifically PFM (active > passive) + education therapies, appear more effective for vaginal, overall pelvic floor, sexual, and PFM function. PFM therapies (active and/or electrostimulation) may improve bladder outcomes. Limited evidence suggests PFM (active) + education therapies may improve bowel function. Conservative therapies may improve psychological function, although available data do not appear to favor a particular therapy. Given the conflicting findings regarding quality of life, no clear conclusions can be made. Interpretation of findings highlighted the importance of intervention dosage, adherence, and supervision for optimal effectiveness. Despite the limitations of the included studies, this review provides new and valuable insights for future research and clinical practice.

Introduction: Lymphatic node metastatic disease encompasses a distinct oncological entity which has been associated with poor prognosis. Image-guided thermal ablation has recently been proposed as a safe and alternative treatment for these lesions. The aim of this systematic review is to evaluate the pooled safety and efficacy of thermal ablation techniques for the treatment of oligometastatic non-cervical lymph nodal disease.

Recent findings: A systematic search of the three major databases (MEDLINE, EMBASE, and CENTRAL) from inception to 30 December 2023 was conducted according to the PRISMA Guidelines. Observational studies reporting technical success, complications and oncologic outcomes were included. Meta- analysis was performed by estimating the pooled incidence rates and risk ratios by fitting random-effect models. Overall, 8 studies were included, comprising of 225 patients and 305 ablated LNMs and a median follow-up of 12 months. The combined data analysis showed that technical success after thermal ablation was 98% (CI: 95%-99%), major complication rate was 1% (CI: 95%-99%), pooled overall response rate was 72% (CI: 54%-87%), local tumor progression rate was 18% (CI: 8%-33%) and disease-free survival rate was 68% (CI: 51%-81%). No difference between radiofrequency ablation and cryoablation was found for every outcome during subgroup analysis. Image-guided percutaneous thermal ablation (with either radiofrequency ablation or cryoablation) is safe and effective for the treatment of oligometastatic LMN disease, however further studies to confirm these findings are still needed.

Purpose of review: This review highlights advances and recent changes in the treatment paradigm for advanced esophageal adenocarcinoma (EAC) and gastroesophageal junction adenocarcinoma (GEJAC).

Recent findings: Chemotherapy remains the backbone of treatment for advanced EAC/GEJAC. New targets/agents include immunotherapy, HER-2, claudin18.2, and FGFR2b, with various mechanisms (CAR-T, bispecific mAB, ADCs) altering the treatment landscape against these targets. The approaches to these targets may act together, in sequence, and even synergistically to improve outcomes. Herein, we review the state of the field, including highlighting ongoing clinical trials and additional emerging agents and approaches.
