Sentinel Lymph Node Biopsy and Management of Regional Lymph Nodes in Melanoma: American Society of Clinical Oncology and Society of Surgical Oncology Clinical Practice Guideline Update.

PURPOSE: To update the American Society of Clinical Oncology (ASCO)-Society of Surgical Oncology (SSO) guideline for sentinel lymph node (SLN) biopsy in melanoma. METHODS: An ASCO-SSO panel was formed, and a systematic review of the literature was conducted regarding SLN biopsy and completion lymph node dissection (CLND) after a positive sentinel node in patients with melanoma. RESULTS: Nine new observational studies, two systematic reviews and an updated randomized controlled trial (RCT) of SLN biopsy, as well as two randomized controlled trials of CLND after positive SLN biopsy, were included. RECOMMENDATIONS: Routine SLN biopsy is not recommended for patients with thin melanomas that are T1a (non-ulcerated lesions < 0.8 mm in Breslow thickness). SLN biopsy may be considered for thin melanomas that are T1b (0.8 to 1.0 mm Breslow thickness or <0.8 mm Breslow thickness with ulceration) after a thorough discussion with the patient of the potential benefits and risk of harms associated with the procedure. SLN biopsy is recommended for patients with intermediate-thickness melanomas (T2 or T3; Breslow thickness of >1.0 to 4.0 mm). SLN biopsy may be recommended for patients with thick melanomas (T4; > 4.0 mm in Breslow thickness), after a discussion of the potential benefits and risks of harm. In the case of a positive SLN biopsy, CLND or careful observation are options for patients with low-risk micrometastatic disease, with due consideration of clinicopathological factors. For higher risk patients, careful observation may be considered only after a thorough discussion with patients about the potential risks and benefits of foregoing CLND. Important qualifying statements outlining relevant clinicopathological factors, and details of the reference patient populations are included within the guideline.

Management of Anxiety and Depression in Adult Survivors of Cancer: ASCO Guideline Update.

PURPOSE: To update the American Society of Clinical Oncology guideline on the management of anxiety and depression in adult cancer survivors. METHODS: A multidisciplinary expert panel convened to update the guideline. A systematic review of evidence published from 2013-2021 was conducted. RESULTS: The evidence base consisted of 17 systematic reviews ± meta analyses (nine for psychosocial interventions, four for physical exercise, three for mindfulness-based stress reduction [MBSR], and one for pharmacologic interventions), and an additional 44 randomized controlled trials. Psychological, educational, and psychosocial interventions led to improvements in depression and anxiety. Evidence for pharmacologic management of depression and anxiety in cancer survivors was inconsistent. The lack of inclusion of survivors from minoritized groups was noted and identified as an important consideration to provide high-quality care for ethnic minority populations. RECOMMENDATIONS: It is recommended to use a stepped-care model, that is, provide the most effective and least resource-intensive intervention based on symptom severity. All oncology patients should be offered education regarding depression and anxiety. For patients with moderate symptoms of depression, clinicians should offer cognitive behavior therapy (CBT), behavioral activation (BA), MBSR, structured physical activity, or empirically supported psychosocial interventions. For patients with moderate symptoms of anxiety, clinicians should offer CBT, BA, structured physical activity, acceptance and commitment therapy, or psychosocial interventions. For patients with severe symptoms of depression or anxiety, clinicians should offer cognitive therapy, BA, CBT, MBSR, or interpersonal therapy. Treating clinicians may offer a pharmacologic regimen for depression or anxiety for patients who do not have access to first-line treatment, prefer pharmacotherapy, have previously responded well to pharmacotherapy, or have not improved following first-line psychological or behavioral management.Additional information is available at www.asco.org/survivorship-guidelines.

Screening, assessment, and care of anxiety and depressive symptoms in adults with cancer: an American Society of Clinical Oncology guideline adaptation.

PURPOSE: A Pan-Canadian Practice Guideline on Screening, Assessment, and Care of Psychosocial Distress (Depression, Anxiety) in Adults With Cancer was identified for adaptation. METHODS: American Society of Clinical Oncology (ASCO) has a policy and set of procedures for adapting clinical practice guidelines developed by other organizations. The guideline was reviewed for developmental rigor and content applicability. RESULTS: On the basis of content review of the pan-Canadian guideline, the ASCO panel agreed that, in general, the recommendations were clear, thorough, based on the most relevant scientific evidence, and presented options that will be acceptable to patients. However, for some topics addressed in the pan-Canadian guideline, the ASCO panel formulated a set of adapted recommendations based on local context and practice beliefs of the ad hoc panel members. It is recommended that all patients with cancer be evaluated for symptoms of depression and anxiety at periodic times across the trajectory of care. Assessment should be performed using validated, published measures and procedures. Depending on levels of symptoms and supplementary information, differing treatment pathways are recommended. Failure to identify and treat anxiety and depression increases the risk for poor quality of life and potential disease-related morbidity and mortality. This guideline adaptation is part of a larger survivorship guideline series. CONCLUSION: Although clinicians may not be able to prevent some of the chronic or late medical effects of cancer, they have a vital role in mitigating the negative emotional and behavioral sequelae. Recognizing and treating effectively those who manifest symptoms of anxiety or depression will reduce the human cost of cancer.

Phase 1 study of escalating-dose OncoGel (ReGel/paclitaxel) depot injection, a controlled-release formulation of paclitaxel, for local management of superficial solid tumor lesions.

OncoGel is a novel depot formulation of paclitaxel designed for intralesional injection with a sustained paclitaxel delivery over approximately 6 weeks from a single administration. This phase 1 study was designed to characterize the toxicity, pharmacokinetics and preliminary antitumor activity associated with OncoGel administered directly into solid tumors. OncoGel was injected into 18 superficially accessible advanced solid cancerous lesions among 16 adult patients for whom no curative therapy was available. Four dose cohorts were evaluated, ranging from 0.06 to 2.0 mg paclitaxel/cm3 tumor volume. OncoGel injections were generally well tolerated. There was one report of grade 3 injection site pain for a patient in the 0.25 mg paclitaxel/cm3 tumor volume dose cohort. Other adverse events considered related to the study drug included mild to moderate local responses to the injection itself. Systemic levels of paclitaxel were detectable only in 3.3% of the samples analyzed (range: 0.53-0.71 ng/ml). For the 14 patients evaluable for disease progression, stable disease was noted among six patients and progressive disease among eight patients. Although the maximum tolerated dose was not identified, the planned maximum dose was administered in the study. OncoGel delivered intralesionally at doses up to 2.0 mg paclitaxel/cm3 tumor volume was well tolerated and paclitaxel remained localized at the injection site, confirming design principles to minimize systemic exposure. Therefore, localized paclitaxel administration using OncoGel merits continued clinical development.
