Exploring the clinical significance of specific immune-related adverse events in melanoma patients undergoing immune checkpoint inhibitor therapy.

Several studies have demonstrated that patients who experience immune-related adverse events (irAE) as a result of immunotherapy treatment, exhibit significantly improved outcomes compared to patients without toxicity. Data regarding the impact of specific irAE is, however, currently lacking. This is a real-world single-site cohort of 415 advanced melanoma patients who were treated with immunotherapy as first-line between 2014 and 2020, with a median follow-up of 24.

Neoadjuvant BRAF-targeted therapy for ameloblastoma of the mandible: an organ preservation approach.

Background: Ameloblastoma is a rare odontogenic neoplasm frequently located in the mandible. Standard treatment involves radical bone resection and immediate reconstruction, causing functional, aesthetic, and psychological impairments. The BRAF V600E mutation is present in approximately 80% of mandible ameloblastomas, and BRAF inhibitors have demonstrated sustained responses in unresectable cases.

Incidence and Outcome of Neurologic Immune-Related Adverse Events Associated With Immune Checkpoint Inhibitors in Patients With Melanoma.

Background And Objectives: Neurologic immune-related adverse events (n-irAEs) reportedly occur in up to 8% of patients treated with immune checkpoint inhibitors (ICIs) of all age groups. We investigated the association between age and n-irAEs in patients treated with ICIs and examined the effect of n-irAEs on survival outcomes in a large cohort of patients with melanoma.

Methods: We conducted a retrospective analysis of patients with advanced melanoma treated with ICIs at Ella Institute for Immuno-oncology and Melanoma between January 1, 2015, and April 20, 2022.

PET-CT underestimates the true pathological extent of disease at lymphadenectomy for melanoma patients after systemic therapy.

Introduction: Modern systemic therapy has revolutionized the treatment of melanoma. Currently, patients with clinically involved lymph nodes require lymphadenectomy with associated morbidities. Positron Emission Tomography - Computed Tomography (PET-CT) has demonstrated accuracy in melanoma detection and response to therapy.

Better Late Than Never: The Impact of Steroidal Treatment on the Outcome of Melanoma Patients Treated with Immunotherapy.

Background: Successful treatment with Immune Checkpoint Inhibitors (ICI) requires the balanced activation of the immune system. Over-activation may result in immune-related adverse events (irAEs), which often require steroidal treatment. This study examined the possible impact of steroids on treatment efficacy in melanoma patients concerning initiation timing and dosage.

Real world evidence of Lenvatinib + anti PD-1 as an advanced line for metastatic melanoma.

Introduction: Immunotherapy has revolutionized the prognosis of patients with metastatic melanoma. To date, the most active regimen is the combination of ipilimumab + nivolumab (ipi-nivo) achieving a response rate of nearly 60% and a median survival (OS) of 6 years. However, approximately 40% of patients experience primary resistance, while around 50% experience secondary resistance, highlighting the need for an effective second-line treatment option The recently published results on the use of lenvatinib + pembrolizumab in the advanced line setting led to the adoption of this regimen at our institution.

MYC Induces Immunotherapy and IFNγ Resistance Through Downregulation of JAK2.

Immunotherapy has revolutionized the treatment of advanced melanoma. Because the pathways mediating resistance to immunotherapy are largely unknown, we conducted transcriptome profiling of preimmunotherapy tumor biopsies from patients with melanoma that received PD-1 blockade or adoptive cell therapy with tumor-infiltrating lymphocytes. We identified two melanoma-intrinsic, mutually exclusive gene programs, which were controlled by IFNγ and MYC, and the association with immunotherapy outcome.

Efficacy and toxicity of Ipilimumab-Nivolumab combination therapy in elderly metastatic melanoma patients.

Introduction: Immunotherapy has revolutionized metastatic Melanoma therapy. The most active regimen is combination therapy of Ipilimumab-Nivolumab (Ipi-Nivo) with response rates (RR) of ~60% and median overall survival (OS) of ~6 years. Immune-related adverse events (irAE) are common (~60% develop grade 3-4) and pose a challenge when treating frail patients.

Radiotherapy may augment response to immunotherapy in metastatic uveal melanoma patients.

Introduction: Uveal melanoma (UM) is a subtype of melanoma arising from the ocular region. Despite various local therapies available, a significant portion of patients develop distant metastases, primarily to the liver. While cutaneous melanoma is very sensitive to immunotherapy, UM is known to be less responsive and patients were excluded from pivotal clinical trials.

The increasing role of abdominal metastesectomy for malignant melanoma in the era of modern therapeutics.

Background: Metastatic spread of malignant melanoma to the abdomen presents a therapeutic challenge. Targeted and Immune-therapies dramatically improve patients' survival, yet some patients may still benefit from surgical intervention. This study investigates the outcomes of surgical treatment of abdominal metastatic melanoma in the era of modern therapy.

Immunotherapy Discontinuation in Metastatic Melanoma: Lessons from Real-Life Clinical Experience.

Background: Immunotherapy has revolutionized outcomes for melanoma patients, by significantly prolonging survival and probably even curing a fraction of metastatic patients. In daily practice, treatment for responding patients is often discontinued due to treatment-limiting toxicity, or electively, following a major tumor response. To date, the criteria for a safe stop and the optimal duration of treatment remain unclear.

Comparison of non-myeloablative lymphodepleting preconditioning regimens in patients undergoing adoptive T cell therapy.

Background: Adoptive cell therapy with T cells genetically engineered to express a chimeric antigen receptor (CAR-T) or tumor-infiltrating T lymphocytes (TIL) demonstrates impressive clinical results in patients with cancer. Lymphodepleting preconditioning prior to cell infusion is an integral part of all adoptive T cell therapies. However, to date, there is no standardization and no data comparing different non-myeloablative (NMA) regimens.

Fecal microbiota transplant promotes response in immunotherapy-refractory melanoma patients.

The gut microbiome has been shown to influence the response of tumors to anti-PD-1 (programmed cell death-1) immunotherapy in preclinical mouse models and observational patient cohorts. However, modulation of gut microbiota in cancer patients has not been investigated in clinical trials. In this study, we performed a phase 1 clinical trial to assess the safety and feasibility of fecal microbiota transplantation (FMT) and reinduction of anti-PD-1 immunotherapy in 10 patients with anti-PD-1-refractory metastatic melanoma.

Real World Outcomes of Ipilimumab and Nivolumab in Patients with Metastatic Melanoma.

Immunotherapy has drastically changed the outlook for melanoma patients over the past decade. Specifically, the dual blockade of immune checkpoints using ipilimumab and nivolumab has shown unprecedented response rates and survival outcomes. This immense achievement, though, is at the cost of toxicity, with 60% of the patients experiencing high-grade adverse events (AEs).

Comprehensive single institute experience with melanoma TIL: Long term clinical results, toxicity profile, and prognostic factors of response.

Adoptive cell transfer (ACT) of tumor-infiltrating lymphocytes (TIL) mediates objective responses in 30% to 50% of patients with metastatic melanoma according to multiple, small phase 2 trials. Here we report the long-term clinical results, intent-to-treat analysis, predictors of response and toxicity profile in a large patient cohort. A total of 179 refractory melanoma patients were enrolled in the ACT trial.

Immune Checkpoint Inhibitor Therapy in Patients With Preexisting Inflammatory Bowel Disease.

Purpose: The risk of immune checkpoint inhibitor therapy-related GI adverse events in patients with cancer and inflammatory bowel disease (IBD) has not been well described. We characterized GI adverse events in patients with underlying IBD who received immune checkpoint inhibitors.

Patients And Methods: We performed a multicenter, retrospective study of patients with documented IBD who received immune checkpoint inhibitor therapy between January 2010 and February 2019.

TNFSF4 (OX40L) expression and survival in locally advanced and metastatic melanoma.

Immunotherapy with checkpoint inhibitors revolutionized melanoma treatment in both the adjuvant and metastatic setting, yet not all metastatic patients respond, and metastatic disease still often recurs among immunotherapy-treated patients with locally advanced disease. TNFSF4 is a co-stimulatory checkpoint protein expressed by several types of immune and non-immune cells, and was shown in the past to enhance the anti-neoplastic activity of T cells. Here, we assessed its expression in melanoma and its association with outcome in locally advanced and metastatic disease.

Recurrent Pneumonitis in Patients with Melanoma Treated with Immune Checkpoint Inhibitors.

Introduction: Immune checkpoint inhibitors (ICIs) have changed the oncologic landscape in the past few years. Alongside impressive antitumor responses, new novel immune-related adverse events (irAEs) have emerged; pneumonitis is an irAE that can potentially be fatal and necessitates a proper management. No consensus exists regarding steroid treatment duration or drug rechallenge options.

Immunotherapy comes of age in octagenarian and nonagenarian metastatic melanoma patients.

Immunotherapy with anti-programmed cell death-1 (PD-1) agents is an effective treatment for metastatic melanoma. Recent data hint at better response to therapy for patients over age 65 years. Patients with metastatic melanoma in their 80's and 90's pose a clinical challenge.

Clinical Significance of Pancreatic Atrophy Induced by Immune-Checkpoint Inhibitors: A Case-Control Study.

Immune-checkpoint inhibitor (ICI)-related diarrhea is attributed to inflammatory colitis, with no other drug-related differential diagnosis. Here, we investigated the occurrence of pancreatic atrophy (PA) in ICI-treated cancer patients and its correlation to exocrine pancreatic insufficiency (EPI). Metastatic melanoma, non-small cell lung carcinoma, and head and neck squamous cell carcinoma patients ( = 403) treated with anti-PD-1 ( = 356) or anti-CTLA-4 ( = 47) were divided into a case group (radiologic evidence of PA); control group matched by age, gender, and previous lines of treatment; and colitis group (ICI-induced colitis).

Possible immune adverse events as predictors of durable response to BRAF inhibitors in patients with BRAF V600-mutant metastatic melanoma.

BRAF inhibitors (BRAFi) and MEK inhibitors (MEKi) are among the cornerstones of metastatic melanoma therapy demonstrating excellent response rates with duration of 7-12 m. Long-term benefit from these agents was reported in patients with normal lactate dehydrogenase (LDH) and less than three disease sites. However, a treatment-dependent marker for long-term efficacy is lacking.

Perioperative BRAF inhibitors in locally advanced stage III melanoma.

Background And Objectives: Stage III malignant melanoma is a heterogeneous disease where those cases deemed marginally resectable or irresecatble are frequently incurable by surgery alone. Targeted therapy takes advantage of the high incidence of BRAF mutations in melanomas, most notably the V600E mutation. These agents have rarely been used in a neoadjuvant setting prior to surgery.
