RESUMEN
BACKGROUND: While cutaneous melanomas are well-documented, primary melanoma of the lung (PMML), particularly with endobronchial origin, remains rare and poorly characterized. This case report addresses gaps in understanding by presenting a comprehensive case of a 71-year-old male with primary endobronchial melanoma and conducting a systematic review of PMML cases. CASE PRESENTATION: The patient, a former smoker, presented with dyspnea, cough, and hemoptysis. Imaging revealed left lung atelectasis and a suspicious nodule. Bronchoscopy identified an endobronchial mass, subsequently treated with argon plasma coagulation and resection. Biopsy confirmed melanoma. Extensive examinations ruled out a primary skin lesion. Despite initial treatment, recurrence led to pneumonectomy. Histopathology confirmed melanoma. The patient received treatment with pembrolizumab and ipilimumab, but with poor clinical benefit. CONCLUSIONS: Primary endobronchial melanoma is a rare entity, comprising 0.01% of lung tumors. This case underscores diagnostic challenges and emphasizes histological criteria to distinguish primary from metastatic lesions. The pathogenesis remains unclear, with theories proposing foetal melanocyte migration or squamous metaplasia. Prognosis varies, necessitating radical surgical extirpation. A systematic review revealed diverse outcomes, supporting the need for further research. In conclusion, endobronchial melanoma involves an endoscopic and surgical management, but evolving therapies, such as immunotherapy, may reshape treatment paradigms. This case contributes to our understanding of PMML, guiding future research and clinical management. As therapeutic options evolve, continued research is crucial to refine our understanding and improve outcomes for this rare malignancy.

BACKGROUND: There is a concern that influenza vaccination may increase the incidence of immune-related adverse events in patients receiving immune checkpoint inhibitors (ICIs). The aim of this systematic review was to summarize the available data on the safety and efficacy of influenza vaccination in cancer patients receiving ICIs. METHODS: Studies reporting safety and efficacy outcomes of influenza vaccination in cancer patients receiving ICIs were included. Only descriptive statistics were conducted to obtain a pooled rate of immune-related adverse events in vaccinated patients. RESULTS: Ten studies assessing the safety and eight assessing the efficacy of influenza vaccination in cancer patients receiving ICIs were identified, for a total of 1124 and 986 vaccinated patients, respectively. Most patients had melanoma or lung cancer and received a single agent anti-PD-1, but also other tumour types and immunotherapy combinations were represented. No severe vaccination-related toxicities were reported. The pooled incidence of any grade immune checkpoint inhibitor-related adverse events was 28.9%. In the 6 studies specifying the incidence of grade 3-4 toxicities, the pooled incidence was 7.5%. No grade 5 toxicities were reported. No pooled descriptive analysis was conducted in studies reporting efficacy outcomes due to the heterogeneity of endpoints and data reporting. Nevertheless, among the eight studies included, seven reported positive efficacy outcomes of influenza vaccination. CONCLUSION: The results of this systematic review support the safety and efficacy of influenza vaccination in cancer patients receiving ICIs. These results are particularly relevant in the context of the SARS-CoV-2 pandemic.

BACKGROUND: Treatment beyond progression with immunotherapy may be appropriate in selected patients based on the potential for late responses. The aim of this systematic review was to explore the impact of treatment beyond progression in patients receiving an anti-PD-1/PD-L1 based regimen for an advanced solid tumor. METHODS: A systematic literature search was performed to identify prospective clinical trials reporting data on overall response rate by immune-related criteria and/or the number of patients treated beyond conventional criteria-defined PD and/or the number of patients achieving a clinical benefit after an initial PD with regimens including an anti-PD-1/PD-L1 agent which received the FDA approval for the treatment of an advanced solid tumor. RESULTS: 254 (4.6%) responses after an initial RECIST-defined progressive disease were observed among 5588 patients, based on 35 trials included in our analysis reporting this information. The overall rate of patients receiving treatment beyond progressive disease was 30.2%, based on data on 5334 patients enrolled in 36 trials, and the rate of patients who achieved an unconventional response among those treated beyond progressive disease was 19.7% (based on 25 trials for a total of 853 patients). CONCLUSION: The results of our systematic review support the clinical relevance of unconventional responses to anti-PD-1/PD-L1-based regimens; however, most publications provided only partial information regarding immune-related clinical activity, or did not provide any information at all, highlighting the need of a more comprehensive report of such data in trials investigating immunotherapy for the treatment of patients with advanced tumors.

The past 5 years have witnessed the results of many practice-changing studies that have dramatically improved the landscape of adjuvant therapy in patients with resected, high-risk melanoma. After a 20-year era of adjuvant interferon, the anti-CTLA-4 and anti-PD-1 immune-checkpoint inhibitors, and MAPK-directed targeted therapy brought a revolution into the adjuvant treatment of melanoma. These results came along with the practice-changing results of two large multicenter studies showing no benefit in terms of overall survival for completion lymph node dissection after positive sentinel node biopsy. In this review, we summarized the current state of the art of the adjuvant treatment of high-risk melanoma, with a view on future perspectives.

Melanoma has always been described as an immunogenic tumor. Despite that, until 2011 the standard of care in metastatic melanoma was chemotherapy, with low response rates and no clear impact on overall survival. Melanoma was the first cancer type to drive the use of immune-checkpoint inhibitors into clinical practice, which revolutionized the therapeutic paradigm not only in melanoma, but also in an increasing number of tumors. In this review, the preclinical bases and the main clinical studies that led to the approval of immune-checkpoint inhibitors in advanced melanoma will be described with insights on novel combinations of treatments and on prognostic and predictive biomarkers.

Immune checkpoint inhibitors, including ipilimumab (IPI), achieve a clinical benefit in a small proportion of melanoma patients highlighting the need to investigate predictive biomarkers. In this study, we characterized tumor infiltrating lymphocytes (TILs), focusing on the CTLA-4+ subset, and evaluated their possible predictive significance. We characterized TIL density, cell type, and localization in 40 melanoma lesions from 17 patients treated with IPI. Associations of TILs with IPI timing, tissue localization, and response to IPI were estimated using a linear mixed-effects modelling approach. We found that most of TIL subsets increased in situ upon IPI therapy, with particular reference to FoxP3+ cells. TILs and TIL subsets, such as CD3+, CD45RO+, CTLA-4+, CD4+, CD8+ T cells, CD20+ B cells, and NKp46+ NK cells, showed significantly different spatial distributions in the tumor microenvironment being higher at the invasive margin (IM) as compared to the tumor center (TC) (P value < 0.001 for TIL score and P value < 0.05 for all subsets). Remarkably, high TIL score and density of CD3+, CD8+ T cells, and CTLA-4+ immune cells were significantly associated with a better response to IPI (P values = 0.002, 0.023, 0.007, and 0.001, respectively, for responders vs non-responders). In conclusion, we provide a detailed analysis of CTLA-4+ TIL distribution in melanoma tissues taking into account localization, relationship with CD3+/CD8+ TILs, and changes in response to IPI treatment. We identified that CTLA-4+ TILs may represent a marker of IPI response, alone or with CD3+/CD8+ subsets, although this requires confirmation in larger studies.

In recent years, advances in melanoma treatment have renewed patient hope. This comprehensive review emphasizes the evolving treatment landscape, particularly highlighting first-line strategies and the interplay between immune-checkpoint inhibitors (ICIs) and targeted therapies. Ipilimumab plus nivolumab has achieved the best median overall survival, exceeding 70 months. However, the introduction of new ICIs, like relatlimab, has added complexity to first-line therapy decisions. Our aim is to guide clinicians in making personalized treatment decisions. Various features, including brain metastases, PD-L1 expression, BRAF mutation, performance status, and prior adjuvant therapy, significantly impact the direction of advanced melanoma treatment. We also provide the latest insights into the treatment of rare melanoma subtypes, such as uveal melanoma, where tebentafusp has shown promising improvements in overall survival for metastatic uveal melanoma patients. This review provides invaluable insights for clinicians, enabling informed treatment choices and deepening our understanding of the multifaceted challenges associated with advanced melanoma management.

Previous studies showed an association between single nucleotide gene variants (SNVs) of PD-1 and cancer susceptibility. We analyzed PD1.5 C > T and PD1.7 T > C SNVs to investigate their association with the risk of developing metastatic melanoma (MM). Utilizing a cohort of 125 MM patients treated with anti-PD-1 agents and 84 healthy controls, we examined genotype/allele frequencies through a modified Poisson regression model, adjusted for age and sex. Our findings indicate that the PD1.5 T allele is associated with a reduced risk of MM, showing a significantly lower risk in both codominant (RR = 0.56, 95%CL: 0.37-0.87) and dominant (RR = 0.73 95%CL: 0.59-0.90) models. Conversely, the PD1.7 C allele is linked to an increased risk of MM, with the C/C genotype exhibiting a higher risk in the codominant (RR = 1.65, 95%CL: 1.32-2.05) and allelic (RR = 1.23, 95%CL: 1.06-1.43) models. These results are consistent with previous meta-analyses on other cancer types, mainly highlighting the PD1.5 SNV's potential role in promoting anti-tumor immunity through increased PD1-positive circulating effector T cell activity.

BACKGROUND: Treatment options for advanced melanoma have increased with the US Food and Drug Administration approval of the anti-LAG3 plus anti-PD-1 relatlimab/nivolumab combination. To date, ipilimumab/nivolumab is the benchmark of overall survival, despite a high toxicity profile. Furthermore, in BRAF-mutant patients, BRAF/MEK inhibitors and the atezolizumab/vemurafenib/cobimetinib triplet are also available treatments, making the first-line therapy selection more complex. To address this issue, we conducted a systematic review and network meta-analysis of the available first-line treatment options in advanced melanoma. METHODS: Randomised clinical trials of previously untreated, advanced melanoma were included if at least one intervention arm contained a BRAF/MEK or an immune-checkpoint inhibitor (ICI). The aim was to indirectly compare the ICIs combinations ipilimumab/nivolumab and relatlimab/nivolumab, and these combinations with all the other first-line treatment options for advanced melanoma (irrespective of BRAF status) in terms of activity and safety. The coprimary end-points were progression-free survival (PFS), overall response rate (ORR) and grade ≥3 treatment-related adverse events (≥ G3 TRAEs) rate, defined according to Common Terminology Criteria for Adverse Events. RESULTS: A total of 9070 metastatic melanoma patients treated in 18 randomised clinical trials were included in the network meta-analysis. No difference in PFS and ORR was observed between ipilimumab/nivolumab and relatlimab/nivolumab (HR = 0.99 [95% CI 0.75-1.31] and RR = 0.99 [95% CI 0.78-1.27], respectively). The PD-(L)1/BRAF/MEK inhibitors triplet combinations were superior to ipilimumab/nivolumab in terms of both PFS (HR = 0.56 [95% CI 0.37-0.84]) and ORR (RR = 3.07 [95% CI 1.61-5.85]). Ipilimumab/nivolumab showed the highest risk of developing ≥ G3 TRAEs. Relatlimab/nivolumab trended to a lower risk of ≥ G3 TRAEs (RR = 0.71 [95% CI 0.30-1.67]) versus ipilimumab/nivolumab. CONCLUSION: Relatlimab/nivolumab showed similar PFS and ORR compared to ipilimumab/nivolumab, with a trend for a better safety profile.

The first-line therapy in advanced kidney cancer has changed in recent years due to the introduction of combinations of tyrosine kinase inhibitors (TKIs) of vascular endothelial growth factor receptors (VEGFR) and immune checkpoint inhibitors (ICIs). Although immune-related adverse events are well-known, in the case of combination treatments, the determination of which drug is related to an adverse event may be challenging. We reported two cases of patients who developed muscle enzyme elevation in association with hypothyroidism during therapy with pembrolizumab plus axitinib for metastatic kidney cancer. The myopathy rapidly resolved after hormone replacement therapy with levothyroxine. Hypothyroid myopathy is a scarcely known and underreported adverse event. This adverse event may be relevant in the differential diagnosis with immune-related myositis, which has an autoimmune pathogenesis and a potentially fatal course.
RESUMEN
Major advances have been made in CRC treatment in recent years, especially in molecularly driven therapies and immunotherapy. Despite this, a large number of advanced colorectal cancer patients do not benefit from these treatments and their prognosis remains poor. The landscape of DNA damage response (DDR) alterations is emerging as a novel target for treatment in different cancer types. PARP inhibitors have been approved for the treatment of ovarian, breast, pancreatic, and prostate cancers carrying deleterious BRCA1/2 pathogenic variants or homologous recombination repair (HRR) deficiency (HRD). Recent research reported on the emerging role of HRD in CRC and showed that alterations in these genes, either germline or somatic, are carried by up to 15-20% of CRCs. However, the role of HRD is still widely unknown, and few data about their clinical impact are available, especially in CRC patients. In this review, we report preclinical and clinical data currently available on DDR inhibitors in CRC. We also emphasize the predictive role of DDR mutations in response to platinum-based chemotherapy and the potential clinical role of DDR inhibitors. More preclinical and clinical trials are required to better understand the impact of DDR alterations in CRC patients and the therapeutic opportunities with novel DDR inhibitors.
RESUMEN
Cutaneous squamous cell carcinoma (CSCC) accounts for approximately 20% of all keratinocytic tumors. In most cases, the diagnosis and treatments are made on small, low-risk lesions. However, in about 5% of cases, CSCC may present as either locally advanced or metastatic (i.e. with locoregional lymph nodes metastases or distant localizations). Prior to the introduction of immunotherapy in clinical practice, the standard treatment of advanced CSCC was not clearly defined, and up to 60% of patients received no systemic therapy. Thanks to a strong pre-clinical rationale, clinical trials led to the FDA (Food and Drug Administration) and EMA (European Medicines Agency) registration of cemiplimab, a PD-1 inhibitor that achieved encouraging results in terms of objective response, overall survival, and quality of life. Subsequently, the anti-PD-1 pembrolizumab received the approval for the treatment of advanced CSCC by the FDA only. In this review, we will focus on the definition of advanced CSCC and on the current and future therapeutic options, with a particular regard for immunotherapy.
RESUMEN
A significant number of women receive a cancer diagnosis before their age of natural menopause. Among these patients, the most frequent neoplasms are breast cancer, gynecological, and hematological malignancies. Premature ovarian insufficiency and infertility are among the most feared short- to long-term consequences of anticancer treatments in premenopausal patients. Both patient- and treatment-related characteristics are key factors in influencing the risk of gonadotoxicity with the use of chemotherapy. The cryopreservation of oocytes/embryos is a standard strategy for fertility preservations offered to young women interested in future family planning, but it does not allow gonadal function protection during chemotherapy. Ovarian suppression with gonadotropin-releasing hormone agonist (GnRHa) during chemotherapy is now recommended as an option to reduce the risk of gonadotoxicity in order to avoid the negative consequences of premature ovarian insufficiency in premenopausal women receiving cytotoxic therapy, including those not interested in fertility preservation. This review summarizes the risk of treatment-induced gonadotoxicity in premenopausal patients and the evidence available on the protective role of administering GnRHa during chemotherapy to preserve ovarian function.
RESUMEN
Merkel cell carcinoma (MCC) is a rare, highly aggressive, neuroendocrine cutaneous tumor. The incidence of MCC is growing worldwide, and the disease-related mortality is about three-fold higher than melanoma. Since a few years ago, very little has been known about this disease, and chemotherapy has been the standard of care. Nowadays, new discoveries about the pathophysiology of this neoplasm and the introduction of immunotherapy allowed to completely rewrite the history of these patients. In this review, we provide a summary of the most important changes in the management of Merkel cell carcinoma, with a focus on immunotherapy and a landscape of future treatment strategies.
RESUMEN
BACKGROUND: Immune checkpoint inhibitors (ICIs) have revolutionised clinical practice in oncology in the last years, leading to a survival benefit in several tumour types. To investigate whether these benefits are associated with improved quality of life, we conducted a systematic review and meta-analysis comparing patient-reported outcomes (PROs) between ICIs and standard chemotherapy (CT) in patients with advanced solid tumours. METHODS: Clinical trials comparing the efficacy of ICIs (either programmed death receptor-1 and programmed death-ligand 1 inhibitors or cytotoxic T-lymphocyte antigen 4 inhibitors, as single agent or in combination) versus CT were included. Trials evaluating treatment with ICIs plus CT versus CT alone were also included, whereas studies in which the control arm included other anticancer agents (such as targeted therapy and other ICIs) or placebo alone were excluded. The aim of our meta-analysis was to compare PROs in subjects treated with ICIs or ICIs plus CT (intervention) with those reported by patients receiving CT (control). The co-primary endpoints were time from baseline to first deterioration in PROs, defined as the time from baseline to the first clinically significant deterioration in PROs, and the changes in PROs from baseline to follow-up between ICI and CT treatment groups (PROSPERO registration number CRD42021247440). RESULTS: A total of 8341 patients from 17 randomised trials of ICI versus CT were included in the analysis. Treatment with ICI delayed clinical deterioration over standard CT in Global Health Status/QoL EORTC QLQ-C30 (hazard ratio [HR] 0.81; 95% confidence interval [CI], 0.74-0.89), and in both EQ-5D utility index (HR 0.65; 95% CI, 0.52-0.82) and EQ-5D visual analogue scale (VAS; HR 0.70; 95% CI, 0.61-0.80). The difference in mean change between the ICI-treated group and the CT-treated group was 5.82 (95% CI, 4.11-7.53) in favour of ICI. Similarly, in the EQ-5D, the mean change differences favoured treatment with ICIs in both Utility Index and VAS, with differences of 0.05 (95% CI, 0.03-0.07) and 5.41 (95% CI, 3.39-7.43), respectively. CONCLUSIONS: ICIs are associated with higher levels of quality of life and longer time to clinical deterioration on several PROs scales compared with CT in different types of solid tumours.

Introduction: In recent years, the introduction of targeted therapy and immunotherapy into clinical practice has radically changed the management of advanced melanoma. More recently, these treatments also became the standard of care in the adjuvant setting. However, high-risk resectable stage III melanoma (i.e. with clinically detected regional lymph node involvement and/or satellites/in transit metastases) still has a high risk of relapse, even after adjuvant treatment, suggesting that the activity of immunotherapy and targeted therapy may play a relevant role in a neoadjuvant setting.Area covered: In this review, we discuss the results of the main clinical trials conducted in the neoadjuvant setting for patients with resectable stage III and stage IV melanoma, with a focus on the hot topics and a look at the future perspectives of the field.Expert opinion: The long-term effects of immunotherapy and the high response rate of targeted therapy provided the strong rationale to start neoadjuvant clinical trials for patients with resectable stage III and oligometastatic stage IV melanoma. Neoadjuvant therapy may play an important role not only for its possible impact on overall survival, but also as a predictive biological marker to allow for a more accurate personalization of adjuvant treatments.

Adjuvant treatment of operated melanoma has deeply changed in the last few years with the introduction of immune-checkpoint inhibitors and BRAF/MEK inhibitors. Sarcoidosis is a systemic inflammatory disease causing non-caseous granulomatous reactions. Sarcoid-like granulomatous reactions have been reported in patients with advanced melanoma, mostly related to immunotherapy with immune-checkpoint inhibitors. We report a case of a 38-year-old woman with stage III operated melanoma treated with adjuvant BRAF plus MEK inhibitors, who developed sarcoidosis-like syndrome with systemic involvement, resolved after discontinuation of treatment. The occurrence of immune-related toxicity with the use of MAPK inhibitors supports the hypothesis that this class of drugs may also have an immunological effect, and that the long-term efficacy of adjuvant MAPK inhibitors may be due to their immunological function.

Melanoma is one of the most aggressive tumors of the skin, and its incidence is growing worldwide. Historically considered a drug resistant disease, since 2011 the therapeutic landscape of melanoma has radically changed. Indeed, the improved knowledge of the immune system and its interactions with the tumor, and the ever more thorough molecular characterization of the disease, has allowed the development of immunotherapy on the one hand, and molecular target therapies on the other. The increased availability of more performing technologies like Next-Generation Sequencing (NGS), and the availability of increasingly large genetic panels, allows the identification of several potential therapeutic targets. In light of this, numerous clinical and preclinical trials are ongoing, to identify new molecular targets. Here, we review the landscape of mutated non-BRAF skin melanoma, in light of recent data deriving from Whole-Exome Sequencing (WES) or Whole-Genome Sequencing (WGS) studies on melanoma cohorts for which information on the mutation rate of each gene was available, for a total of 10 NGS studies and 992 samples, focusing on available, or in experimentation, targeted therapies beyond those targeting mutated BRAF. Namely, we describe 33 established and candidate driver genes altered with frequency greater than 1.5%, and the current status of targeted therapy for each gene. Only 1.1% of the samples showed no coding mutations, whereas 30% showed at least one mutation in the RAS genes (mostly NRAS) and 70% showed mutations outside of the RAS genes, suggesting potential new roads for targeted therapy. Ongoing clinical trials are available for 33.3% of the most frequently altered genes.
RESUMEN
Incidence of melanoma has been constantly growing during the last decades. Although most of the new diagnoses are represented by thin melanomas, the number of melanoma-related deaths in 2018 was 60,712 worldwide (Global Cancer Observatory, 2019). Until 2011, no systemic therapy showed to improve survival in patients with advanced or metastatic melanoma. At that time, standard of care was chemotherapy, with very limited results. The identification of BRAF V600 mutation, and the subsequent introduction of BRAF targeting drugs, radically changed the clinical practice and dramatically improved outcomes. In this review, we will retrace the development of molecular-target drugs and the current therapeutic scenario for patients with BRAF mutated melanoma, from the introduction of BRAF inhibitors as single agents to modern clinical practice. We will also discuss the resistance mechanisms identified so far, and the future therapeutic perspectives in BRAF mutated melanoma.
