Purpose of review: To review the current management of the axilla in breast cancer.

Recent findings: Axillary dissection is no longer indicated in patients with clinically node-negative axilla with 1-2 positive sentinel lymph nodes following upfront surgery or in patients with clinically node-negative axilla following neoadjuvant chemotherapy. Breast cancer has evolved away from routine axillary clearance to the less invasive sentinel lymph node biopsy to now complete omission of axillary sampling in select patients. We will review the most salient evidence that has shaped these practice changes over the last three decades. Current practice controversies are especially relevant for elderly populations and those receiving neoadjuvant therapy. Ongoing clinical trials will provide data to further guide breast cancer surgical management.

Purpose of review: The following review will highlight the development of anamorelin to treat cancer anorexia-cachexia syndrome (CACS) including the potential benefits, limitations, and future directions.

Recent findings: Ghrelin, a 28-amino acid peptide hormone, is secreted by the stomach mucosa and regulates appetite, promotes lipogenesis, increases body weight, improves gastric motility, reduces catabolic wasting and inflammation. Several randomized, double-blind, placebo-controlled clinical trials evaluating anamorelin, a ghrelin agonist, for the treatment of CACS have reported improvement in appetite and body composition including both lean body and fat mass; however, most studies noted no improvement in physical function as assessed by measuring non-dominant hand-grip strength. Common adverse effects of anamorelin include the development of diabetes mellitus, hyperglycemia, and less frequently, hepatic abnormalities and cardiovascular events including conduction abnormalities, hypertension, and ischemic cardiomyopathy. Anamorelin has the potential to stimulate appetite, improve gastric movement, and may have anti-inflammatory effects on patients with CACS. In patients with cancer, studies involving anamorelin combined with other multimodal treatments including nutrition counseling (branched chain amino acids, omega 3 fatty acids, and other nutrients), exercise, treatment of hormonal abnormalities including hypogonadism and hypovitaminosis D, and anti-inflammatory agents are needed. Compliance with multimodality treatment has been a barrier and future studies may need to incorporate motivational counseling to promote adherence.

Purpose of review: This review addresses the current landscape of colorectal cancer (CRC) with a focus on liver metastases, the third most common cancer globally. It explores recent findings in treatment strategies, emphasizing the dynamic interplay between surgery, systemic chemotherapy, and local therapies for synchronous colorectal liver metastases (CRLMs).

Recent findings: Highlighting the role of advanced imaging, the review underscores the significance of contrast-enhanced MRI in surgical planning for CRLMs. Surgical resection remains a primary choice for resectable cases, with considerations for oncologic scoring systems and tumor biology. Perioperative systemic chemotherapy plays a pivotal role, especially in conversion therapy for initially unresectable CRLMs. The review also explores various local therapies, including radiofrequency ablation, microwave ablation, stereotactic body radiotherapy, hepatic arterial infusional chemotherapy, selective internal radiation therapy, and transarterial chemoembolization for unresectable cases. A comprehensive approach, integrating surgery, systemic chemotherapy, and local therapies, is crucial for managing synchronous CRLMs. Surgical resection and perioperative chemotherapy are key players, guided by considerations of tumor biology and scoring systems. For unresectable cases, local therapies offer viable alternatives, emphasizing the need for tailored treatments. Multidisciplinary collaboration among medical oncologists, surgeons, and radiologists is essential. Ongoing research will refine treatment approaches, while emerging technologies hold promise for further advancements in managing colorectal liver metastases.

Purpose of review: There is increasing incidence of renal cell carcinoma (RCC) with multiple treatment options currently available. The purpose of this review is to outline patient selection and technical approaches and present the current literature for percutaneous ablation of T1b (4.1-7 cm) RCC.

Recent findings: An increasing number of retrospective studies and meta-analyses have evaluated the use of percutaneous ablation for T1b RCC. Overall, these studies tend to show that percutaneous ablation in this patient population is feasible. However, rates of major adverse events and local recurrence after percutaneous ablation for T1b RCC are both higher than when ablation is used for smaller tumors. As such, a multi-disciplinary, patient-centered approach is required. Due to the increasing literature in this area, the most recent National Comprehensive Cancer Network (NCCN) guidelines include percutaneous ablation as an option for non-surgical patients with T1b RCC.

Purpose of review: As the treatment landscape for multiple myeloma (MM) continues to expand at a rapid pace, management of older adults and frail patients becomes increasingly challenging. As these patients have traditionally been underrepresented on clinical trials, there is limited guidance on the optimal approach to frail patients with newly diagnosed multiple myeloma (NDMM) or relapsed and refractory multiple myeloma (RRMM).

Recent findings: Frailty is an independent predictor of tolerability and response to antineoplastic treatment. Stringent eligibility criteria have often excluded these patients, but recently some large trials have included frailty sub-analyses to help guide management. In general, triplet regimens are preferred to doublet regimens in this population and enrollment on a clinical trial should be prioritized when possible. In this review, we summarize the MM frailty scoring tools that have been developed to identify and assess this vulnerable population. We present the clinical trials over the past decade that have enrolled frail patients and/or have included subgroup analyses to help elucidate the response and tolerability of different regimens in this underrepresented group. We provide practical advice regarding assessment and management of frail patients NDMM and RRMM.

Purpose of review: Melanoma in younger individuals has different clinical presentations, histologic characteristics and prognosis from older patients. This review summarizes key differences and important new insights into pediatric and young adult melanoma, as well as recent evolutions in treatment.

Recent findings: Molecular techniques have improved the classification of melanocytic neoplasms, and are especially useful in the workup of the diagnostically challenging lesions frequent in this age group. Molecular evaluation highlights differences between melanoma and atypical lesions with Spitz-like morphology, and should routinely be incorporated for diagnosing and classifying Spitzoid melanocytic to guide prognostication and treatment. Once diagnosed, the management of bona fide melanoma in children and young adults is largely similar to older patients, while the optimal management of lesions such as atypical Spitz tumors remains uncertain. Increased awareness of the presentation and diagnostic characteristics of melanoma in young individuals will allow earlier detection, and improved diagnostic techniques will allow optimum management without over- or under-treatment.

Purpose of review: Family/unpaid caregivers play an important role in cancer care. This review aims to summarize caregiver communication experiences with healthcare professionals (HCPs).

Recent findings: The Caregiver-Centered Communication model defines five core functions that HCPs should achieve when interacting with caregivers, including fostering relationships, exchanging information, recognizing and responding to caregiver emotions, aiding in decision making, and assisting in patient care management. The literature shows that caregivers have both positive and negative communication experiences with HCPs with respect to these five core functions. Factors at the caregiver (e.g., demographic characteristics, information sources, caregiving duration, health status), patient (e.g., demographic and clinical characteristics), and HCP levels (e.g., time constraints in clinical settings, communication skills) are associated with caregiver-HCP communication quality. Studies further show that these communication experiences may affect caregiver outcomes, including quality of life, mental health, resilience, and satisfaction with cancer care. Moreover, poor quality caregiver-HCP communication is associated with patient readmission to the hospital and unmet care needs. Interventions for caregivers or patient-caregiver dyads have been shown to enhance caregiver confidence and increase their engagement in communication with HCPs. Interventions for HCPs have shown efficacy in improving their communication skills, particularly in involving caregivers in decision-making discussions. Given time constraints during medical visits, we suggest conducting a caregiver assessment by navigators prior to visits to understand their communication needs. Additionally, reimbursing HCPs for time spent communicating with caregivers during visits could be beneficial. More research is needed to better understand how to enhance caregiver-HCP communication quality.

Background: The journey from radical treatments to the precision of robotic surgery underscores a commitment to innovation and patient-centered care in the field of head and neck oncology.

Purpose of review: This article provides a comprehensive overview that not only informs but also stimulates ongoing discourse and investigation into the optimization of patient care through robotic surgery. The literature on current robotic applications within head and neck region was systematically reviewed.

Recent findings: Thirty-four studies with a total of 1835 patients undergoing robotic surgery in head and neck region were included. Clinical staging, histological types, operative duration, postoperative complications, functional recovery and survival outcomes were compared and evaluated. Clinical outcomes have shown promising results and thus the indication on the robotic usage has no longer been limited to oropharyngeal region but from skull base to neck dissection. The latest advancement in robotic surgery further refines the capabilities of surgeons into previously difficult-to-access head and neck regions and heralds a new era of surgical treatment for head and neck oncology.

Purpose of review: This review aims to assess the literature regarding current treatment options for the palliative care of patients with advanced musculoskeletal malignancies whether primary or metastatic.

Recent findings: The inclusion of specialized palliative care physicians, in conjunction with surgeons, medical oncologists, radiation oncologists, interventional radiologists, and mental health professionals, results in better control of end-of-life symptoms in both children and adults with terminal musculoskeletal malignancies. The palliative care of patients with musculoskeletal malignancies requires a multi-disciplinary team and benefits from specialized palliative care physicians. The unique impacts of musculoskeletal malignancies on ambulation and independence creates additional mental and physical burdens on patients and care-takers alike. Palliative care should focus on preserving ambulatory function and patient independence, in addition to managing chronic pain and other end-of-life symptoms common to these malignancies.

Purpose of the review: Children and adolescents with cancer, along with their parents and other informal caregivers, often report using complementary and alternative medicine (CAM) during active oncology and hemato-oncology treatment. Some adopt an "alternative" approach to conventional medical care, which often entails the use of these practices without the knowledge of the treating pediatrician. In contrast, many others search for consultation provided by a pediatric integrative oncology (IO) practitioner working with the conventional medical team. IO seeks to provide evidence-based complementary medicine therapies, many of which have been shown to augment conventional supportive and palliative care, while ensuring the patient's safety. The present narrative review examines the current state of and future direction for the IO setting of care.

Recent findings: A large body of published clinical research supports the effectiveness of leading Pediatric IO modalities, while addressing potential safety-related concerns. Despite the growing amount of clinical research supporting the beneficial effects and implementation of Pediatric IO models of care, there is still a need for further studies in order to establish clinical guidelines in the treatment of children and adolescents with cancer. Such IO-directed guidelines will need to address both the effectiveness and the safety of the CAM modalities being used in pediatric oncology and hemato-oncology settings, promoting a better understanding among pediatric healthcare professionals and helping them understand the indications for referral to the IO treatment service.
