RESUMO
BACKGROUND: Cutaneous adnexal carcinomas are a heterogeneous group of rare neoplasms. Surgical excision is the first-line treatment in localized stage. The use and effectiveness of radiotherapy have not been thoroughly evaluated in these neoplasms. OBJECTIVES: The present work analyses prognostic factors on outcomes in skin adnexal carcinomas, based on data from the CARADERM (CAncers RAres DERMatologiques) database. METHODS: Data were collected retrospectively including demographic data, tumour types and therapeutic characteristics of all patients included in the CARADERM database, with at least one informative follow-up visit. Analyses were performed on three populations: patients with complete resection of the primary tumour (ADJ/primary population), patients achieving complete remission after complete resection of a recurrent tumour (ADJ/recurrent population) and patients with unresectable locally advanced or metastatic tumours (ADV/MET population). Overall and recurrence/progression-free survivals at 3-year were analysed using Cox regression models. RESULTS: Radiotherapy did not affect overall survival (OS) in the ADJ/primary population. Adjusted recurrence-free survival (RFS) was significantly lower in the radiotherapy group in ADJ/primary group. Older patients had significantly poorer OS and RFS. Tumour size and immunosuppression were significantly associated with poorer RFS only. Radiotherapy had no effect on OS and RFS in the ADJ/recurrent population. Age was the only factor associated with a poorer OS. Radiotherapy was significantly associated with longer progression-free survival (PFS) in age-sex adjusted analysis in the ADV/MET population, without effect on OS. CONCLUSIONS: Our study shows that age, tumour size and immunosuppression are significantly associated with survival in localized adnexal carcinomas. Radiotherapy may improve PFS in the ADV/MET population but not in localized and recurrent carcinomas after complete excision.
RESUMO
BACKGROUND: Phase 1-2 trials involving patients with resectable, macroscopic stage III melanoma have shown that neoadjuvant immunotherapy is more efficacious than adjuvant immunotherapy. METHODS: In this phase 3 trial, we randomly assigned patients with resectable, macroscopic stage III melanoma, in a 1:1 ratio, to receive two cycles of neoadjuvant ipilimumab plus nivolumab and then undergo surgery or to undergo surgery and then receive 12 cycles of adjuvant nivolumab. Only the patients in the neoadjuvant group who had a partial response or nonresponse received subsequent adjuvant treatment. The primary end point was event-free survival. RESULTS: A total of 423 patients underwent randomization. At a median follow-up of 9.9 months, the estimated 12-month event-free survival was 83.7% (99.9% confidence interval [CI], 73.8 to 94.8) in the neoadjuvant group and 57.2% (99.9% CI, 45.1 to 72.7) in the adjuvant group. The difference in restricted mean survival time was 8.00 months (99.9% CI, 4.94 to 11.05; P<0.001; hazard ratio for progression, recurrence, or death, 0.32; 99.9% CI, 0.15 to 0.66). In the neoadjuvant group, 59.0% of the patients had a major pathological response, 8.0% had a partial response, 26.4% had a nonresponse (>50% residual viable tumor), and 2.4% had progression; in 4.2%, surgery had not yet been performed or was omitted. The estimated 12-month recurrence-free survival was 95.1% among patients in the neoadjuvant group who had a major pathological response, 76.1% among those who had a partial response, and 57.0% among those who had a nonresponse. Adverse events of grade 3 or higher that were related to systemic treatment occurred in 29.7% of the patients in the neoadjuvant group and in 14.7% in the adjuvant group. CONCLUSIONS: Among patients with resectable, macroscopic stage III melanoma, neoadjuvant ipilimumab plus nivolumab followed by surgery and response-driven adjuvant therapy resulted in longer event-free survival than surgery followed by adjuvant nivolumab.

RESUMO
The need for reliable biomarkers to predict clinical benefit from anti-PD1 treatment in metastatic melanoma (MM) patients remains unmet. Several parameters have been considered in the tumor environment or the blood, but none has yet achieved sufficient accuracy for routine clinical practice. Whole blood samples from MM patients receiving second-line anti-PD1 treatment (NCT02626065), collected longitudinally, were analyzed by flow cytometry to assess the immune cell subsets absolute numbers, the expression of immune checkpoints or ligands on T cells and the functionality of innate immune cells and T cells. Clinical response was assessed according to Progression-Free Survival (PFS) status at one-year following initiation of anti-PD1 (responders: PFS > 1 year; non-responders: PFS ≤ 1 year). At baseline, several phenotypic and functional alterations in blood immune cells were observed in MM patients compared to healthy donors, but only the proportion of polyfunctional memory CD4+ T cells was associated with response to anti-PD1. Under treatment, a decreased frequency of HVEM on CD4+ and CD8+ T cells after 3 months of treatment identified responding patients, whereas its receptor BTLA was not modulated. Both reduced proportion of CD69-expressing CD4+ and CD8+ T cells and increased number of polyfunctional blood memory T cells after 3 months of treatment were associated with response to anti-PD1. Of upmost importance, the combination of changes of all these markers accurately discriminated between responding and non-responding patients. These results suggest that drugs targeting HVEM/BTLA pathway may be of interest to improve anti-PD1 efficacy.

BACKGROUND: Only a fraction of patients with metastatic melanoma derive durable benefit from approved treatments. The clinical impact of personalized medicine strategies for melanoma, apart from BRAF, NRAS, or CKIT targeting, has rarely been reported. MATERIALS AND METHODS: By means of the Group of Cutaneous Oncology of the French Society of Dermatology, we retrospectively included all patients with advanced melanoma aged 18 years and older for whom molecular testing identified one or more actionable molecular alterations and who accordingly received molecularly matched therapy. We excluded patients with only BRAF, NRAS, or CKIT alterations and patients who received molecularly matched therapy for less than 15 days. RESULTS: We included 26 patients with a median follow-up of 8 months (1-54), a median age of 63 years (24-89), and a sex ratio of 2.7. These patients had been heavily pretreated, and 64% had elevated LDH levels. The disease control rate was 38%, with 4 cases of partial response (overall response rate: 15%) and 6 of stable disease for at least 6 months. The median duration of treatment was 3.1 months (0.9-13.5). Among patients with disease control, the median duration of control was 6.6 months (2.6-13.5) and 3 cases were ongoing at the end of the study. Patients with controlled disease had GNA11, MAP2K1, FYCO1-RAF1, HRAS, ATM, CCND1, MDM2/CDK4, and CDKN2A/NRAS alterations. CONCLUSIONS: High-throughput sequencing followed by matched targeted therapy is a promising approach for patients with advanced melanoma refractory to approved treatments.
RESUMO
PURPOSE: The integration of palliative care (PC) into oncological management is recommended well before the end of life. It improves quality of life and symptom control and reduces the aggressiveness of end-of-life care. However, its appropriate timing is still debated. Entry into an early-phase clinical trial (ECT) represents hopes for the patient when standard treatments have failed. It is an opportune moment to integrate PC to preserve the patient's general health status. The objective of this study was to evaluate the motives for acceptance or refusal of early PC management in patients included in an ECT. METHODS: Patients eligible to enter an ECT were identified and concomitant PC was proposed. All patients received exploratory interviews conducted by a researcher. Their contents were analyzed in a double-blind thematic analysis with a self-determination model. RESULTS: Motives for acceptance (PC acceptors: n = 27) were both intrinsic (e.g., pain relief, psychological support, anticipation of the future) and extrinsic (e.g., trust in the medical profession, for a relative, to support the advance of research). Motives for refusal (PC refusers: n = 3) were solely intrinsic (e.g., PC associated with death, negative representation of psychological support, no need for additional care, claim of independence). CONCLUSIONS: The motives of acceptors and refusers are not internalized in the same way and call for different autonomy needs. Acceptors and refusers are influenced by opposite representations of PC and a different perception of mixed management.

Data regarding elderly melanoma patients treated with anti-PD-1 or anti-CTLA-4 antibodies are in favor of tolerability outcomes that are similar to those of younger counterparts. However, there are very few studies focusing on elderly patients receiving nivolumab combined with ipilimumab (NIVO + IPI). Here, we ask what are the current prescribing patterns of NIVO + IPI in the very elderly population and analyze the tolerance profile. This French multicenter retrospective study was conducted on 60 melanoma patients aged 80 years and older treated with NIVO + IPI between January 2011 and June 2022. The mean age at first NIVO + IPI administration was 83.7 years (range: 79.3-93.3 years). Fifty-five patients (92%) were in good general condition and lived at home. Two dosing regimens were used: NIVO 1 mg/kg + IPI 3 mg/kg Q3W (NIVO1 + IPI3) in 27 patients (45%) and NIVO 3 mg/kg + IPI 1 mg/kg Q3W (NIVO3 + IPI1) in 33 patients (55%). NIVO + IPI was a first-line treatment in 39 patients (65%). The global prevalence of immune-related adverse events was 63% (38/60), with 27% (16/60) being of grade 3 or higher. Grade ≥ 3 adverse events were less frequent in patients treated with NIVO3 + IPI1 compared with those treated with NIVO1 + IPI3 (12% versus 44%, p = 0.04). In conclusion, the prescribing patterns of NIVO + IPI in very elderly patients are heterogeneous in terms of the dosing regimen and line of treatment. The safety profile of NIVO + IPI is reassuring; whether or not the low-dose regimen NIVO3 + IPI1 should be preferred over NIVO1 + IPI3 in patients aged 80 years or older remains an open question.
RESUMO
Surgery is a treatment option for neurofibromatosis type 1 (NF1)-related plexiform neurofibromas (PN), but complete resection is often not feasible. Real-world studies are warranted to understand disease burden, progression, and need for medical treatment in patients with inoperable PN. CASSIOPEA was a retrospective study of French pediatric patients (aged ≥3 to <18 years) presenting at a national multidisciplinary team (MDT) review with NF1 and ≥1 symptomatic, inoperable PN. Medical records were reviewed from the time of MDT review and over a follow-up period of up to 2 years. Primary objectives were to describe patient characteristics and target PN-associated therapy patterns. A secondary objective was evolution of target PN-related morbidities. Patients with prior, ongoing, or MDT recommendation of mitogen-activated protein kinase kinase (MEK) inhibitor treatment were excluded. Overall, 78 target PN were identified in 76 patients. At MDT review, median age was 8.4 years, with approximately 30% of patients aged 3-6 years. Target PN were primarily internal (77.3%), and 43.2% were progressive. Target PN location was evenly distributed. 34 target PN had documented MDT recommendations; of these, a majority (76.5%) were for non-medication management, including surveillance. At least one follow-up visit was recorded for 74 target PN. Despite initially being considered inoperable, 12.3% of patients underwent surgery for target PN. At MDT review, most (98.7%) target PN were associated with ≥1 morbidity, primarily pain (61.5%) and deformity (24.4%); severe morbidities were identified in 10.3%. Of 74 target PN with follow-up data, 89.2% were associated with ≥1 morbidity, primarily pain (60.8%) and deformity (25.7%). Of 45 target PN associated with pain, pain improved in 26.7%, was stable in 44.4%, and deteriorated in 28.9%. Deformity improved in 15.8% and remained stable in 84.2% of 19 target PN associated with deformity. None deteriorated. In this real-world study in France, NF1-PN disease burden was considerable, and a considerable proportion of patients were very young. Most patients received only supportive care without medication for target PN management. Target PN-related morbidities were frequent, heterogeneous, and generally did not improve during follow-up. These data highlight the importance of effective treatments that target PN progression and improve disease burden.

INTRODUCTION: Indications of adjuvant radiotherapy (RT) for high-risk cutaneous squamous cell carcinoma (cSCC) are not clearly defined. We aimed to identify factors predicting relapse in cSCC patients treated with surgery or RT alone and to assess in which clinical setting adjuvant RT was beneficial in term of progression free survival (PFS). METHODS: This retrospective analysis included patients with resectable primary cSCC treated with surgery and/or RT in curative intent, managed at Centre Léon Bérard (Lyon, France) from April 2010 to September 2020. RESULTS: A total of 303 patients with 529 cSCC were included. 31 (5.9%) cSCC were treated with surgery and adjuvant RT. With a median follow-up of 54 (0.2-126) months, 103 (19.5%) cSCC relapsed. In multivariate analysis, the highest predictive factor of relapse in cSCC was the number of risk factors (HR = 15.110 [95% CI: 3.91-58.40] for ≥3 risk factors p < 0.001), followed by poor differentiation (HR = 4.930 [95% CI: 2.47-9.86], p < 0.001) and perineural invasion (HR = 2.442 [95% CI: 1.11-5.38], p = 0.027). For cSCC with ≥3 risk factors, PFS was significantly higher in cSCC treated with surgery and adjuvant RT compared to those treated with surgery or RT alone (the 36-month PFS was 74% [95% CI: 43-90%] and 31% [95% CI: 10-54%] respectively, p = 0.008). CONCLUSION: An increased number of risk factors was identified as being the highest predictive factor of relapse in cSCC. Adjuvant RT improved PFS for high-risk cSCC with ≥3 risk factors.

Background: Skin phototype, latitude and sun exposure are classic risk factors for melanomas but are not relevant to acrolentiginous melanomas (ALM). ALM is not related to chronic sun exposure because the thick stratum corneum acts as a barrier to penetration of UV rays, whereas LMM occurs in skin with high photoaging due to chronic sun exposure. Objectives: This study aimed to determine if any difference exists between "solar" melanomas and "non-solar" melanomas based on a comparison between LMM and ALM. Materials & Methods: We extracted all data for ALM and LMM patients, from March 2012 to September 2020, from the RIC-Mel national database to perform a descriptive cohort analysis of 1,056 Caucasian cases. Conclusion: The profiles of solar-related and non-solar melanoma seem to be different, and prognostic factors of ALM at diagnosis are less favourable compared to LMM, suggesting that non-solar melanoma is more aggressive than solar-related melanoma and that sentinel lymph node biopsy should be performed.

Neurofibromatosis type 1 (NF1) is a disease characterized by high occurrence of benign and malignant brain tumours and caused by mutations of the neurofibromin protein. While there is an increasing evidence that NF1 is associated with radiosensitivity and radiosusceptibility, few studies have dealt with the molecular and cellular radiation response of cells from individuals with NF1. Here, we examined the ATM-dependent signalling and repair pathways of the DNA double-strand breaks (DSB), the key-damage induced by ionizing radiation, in skin fibroblast cell lines from 43 individuals with NF1. Ten minutes after X-rays irradiation, quiescent NF1 fibroblasts showed abnormally low rate of recognized DSB reflected by a low yield of nuclear foci formed by phosphorylated H2AX histones. Irradiated NF1 fibroblasts also presented a delayed radiation-induced nucleoshuttling of the ATM kinase (RIANS), potentially due to a specific binding of ATM to the mutated neurofibromin in cytoplasm. Lastly, NF1 fibroblasts showed abnormally high MRE11 nuclease activity suggesting a high genomic instability after irradiation. A combination of bisphosphonates and statins complemented these impairments by accelerating the RIANS, increasing the yield of recognized DSB and reducing genomic instability. Data from NF1 fibroblasts exposed to radiation in radiotherapy and CT scan conditions confirmed that NF1 belongs to the group of syndromes associated with radiosensitivity and radiosusceptibility.

PURPOSE: In BRAF V600MUT metastatic melanoma, cyclin D-CDK4/6-INK4-Rb pathway alterations are involved in resistance to MAPK inhibitors, suggesting a clinical benefit of cyclin-dependent kinase 4 (CDK4) inhibitors. In this phase I-II study, we aimed to establish the MTD of palbociclib when added to vemurafenib. PATIENTS AND METHODS: Patients with BRAF V600E/KMUT metastatic melanoma harboring CDKN2A loss and RB1 expression were included and stratified into two groups according to previous BRAF inhibitor treatment (no:strata 1; yes:strata 2). Treatment comprised palbociclib once daily for 14 days followed by a 7-day break + continuous dosing of vemurafenib. The primary endpoint was the occurrence of dose-limiting toxicity (DLT), and the secondary endpoints included the best response, survival, pharmacokinetics, and tumor molecular profiling. RESULTS: Eighteen patients were enrolled, with 15 in strata 2. Characteristics at inclusion were American Joint Committee on Cancer stage IVM1c (N = 16; 88.9%), high lactate dehydrogenase (N = 9; 50.0%), and median number of previous treatments of 2. One and 5 patients experienced DLT in strata 1 and 2, respectively, defining the MTD at palbociclib 25 mg and vemurafenib 960 mg in strata 2. No significant evidence for drug-drug interactions was highlighted. The median progression-free survival was 2.8 months, and 5 (27.8%) patients showed a clinical response. The baseline differential mRNA expression analysis and in vitro data revealed the role of CHEK2 in the response to palbociclib. CONCLUSIONS: Although the combination of palbociclib + fixed-dose vemurafenib did not allow an increased palbociclib dosage above 25 mg, a significant clinical benefit was achieved in pretreated patients with melanoma. An association between the transcriptomic data and clinical response was highlighted.

New anti-cancer therapeutics have been developed in the recent years and dramatically change prognosis and patient management. Either used alone or in combination, immune checkpoint inhibitors (ICI), such as anti-CTLA-4 and anti-PD1/PD-(L)1, act by removing T-cell inhibition to enhance their antitumor response. This change in therapeutic targets leads to a break in immune-tolerance and a unique toxicity profile resulting in immune complications. These side effects, called Immune-Related Adverse Events (IrAEs), can affect all organs, with a wide range of clinical and biological presentations and severity. Various rheumatic and musculoskeletal manifestations have been reported in the literature, ranging from mild arthralgia, polymyalgia rheumatica, to genuine serodefined rheumatoid arthritis and myositis. Tolerance studies suggest some correlations between IrAEs occurrence and tumor response. Assessment of patient musculoskeletal status prior to the start of the ICI is warranted. Management of rheumatic IrAEs does not usually request ICI discontinuation, exception for myositis or very severe forms where it should be discussed. Treatment relies on non-steroidal anti-inflammatory drugs (NSAIDs) or low dose glucocortioids (<20mg per day). Dose should be adjusted according to severity. The use of disease modifying anti-rheumatic drugs (DMARDs), either conventional and/or biological should be very cautious and result from a shared decision between oncologist and rheumatologist to best manage dysimmunitary complications without hampering the antitumor efficacy of ICI.

Importance: Since 2011, many patients with metastatic melanoma have been treated with ipilimumab therapy and have developed severe immune-related adverse events (AEs). Because several immune therapies are now available to treat metastatic melanoma, a better knowledge of mechanisms and recurrence risks of immune-related AEs is needed before reintroduction of immunotherapies. Objectives: To evaluate the risk of a recurrence of immune toxic effects associated with anti-programmed cell death 1 antibody (anti-PD-1) therapy after discontinuation of ipilimumab monotherapy because of severe AEs. Design, Settings, and Participants: This cohort study conducted at 19 French melanoma referral centers included patients with metastatic melanoma who experienced severe immune-related AEs after ipilimumab therapy and then were treated with anti-PD-1 therapy between February 1, 2013, and December 31, 2016. The study cutoff was June 1, 2017. Statistical analysis was performed from June 1, 2016, to August 31, 2017. Exposures: Monotherapy with at least 1 cycle of ipilimumab that was associated with a grade 3 or 4 immune-related AE and subsequent treatment with at least 1 cycle of an anti-PD-1 (nivolumab or pembrolizumab) therapy. Main Outcomes and Measures: The primary outcome was the rate of immune-related AEs associated with anti-PD-1 therapy. Secondary outcomes were characteristics of ipilimumab-related and anti-PD-1 immune-related AEs and overall response rate and overall survival associated with anti-PD-1 therapy. Results: Of 56 patients with metastatic melanoma included in the study, all of whom experienced severe immune-related AEs after ipilimumab therapy (31 [55%] male; mean [SD] age, 64 [14.9] years), 20 (36%) experienced at least 1 immune-related AE associated with pembrolizumab (6 of 20 [30%]) or nivolumab (14 of 20 [70%]) therapy. A total of 12 patients (21%) experienced grade 3 or 4 immune-related AEs, and among these patients, 4 (33%) presented with the same immune-related AE as with ipilimumab therapy. Severe immune-related AEs were resolved with use of systemic corticosteroids (7 [58%]) and/or anti-tumor necrosis factor (1 [8%]), and no grade 5 toxic effects were reported. Five patients discontinued anti-PD-1 therapy because of immune-related AEs. The overall response rate was 43%, with a median overall survival of 21 months (interquartile range, 18 to ongoing). Conclusions and Relevance: The findings suggest that anti-PD-1 therapy may be associated with reduced risk of toxic effects and improved survival among patients who have experienced severe toxic effects after ipilimumab therapy.

BRAF and MEKis have revolutionized the management of BRAFV600 -mutated melanoma patients. Left ventricular ejection fraction decrease (LVEF-D) related to these treatments has not been thoroughly evaluated to date. The main objective of this study was to describe characteristics of LVEF-D in melanoma patients treated with BRAF and/or MEKis. Metastatic melanoma patients treated with BRAF and/or MEKis between March 1, 2012 and May 18, 2018 were included retrospectively (Lyon Sud University Hospital, Hospices Civils de Lyon). LVEF-D was defined as a reduction in LVEF ≥10% from baseline to a value <55%; normalization was defined as a value ≥55%. Among the 88 patients included, 12 (13.6%) experienced a LVEF-D, including 10 grade 2 and 2 grade 3. The median onset of which was 11 months (IQR [3-21]). No patient previously treated with beta-blockers (n = 12) experienced a LVEF-D. Analysis of laboratory parameters, electrocardiogram, and transthoracic echocardiography during the follow-up did not find any predictive marker of LVEF-D. All patients who benefited from a specific treatment of LVEF-D had a normalization of LVEF at the end of follow-up. LVEF recovery was significantly better for patients treated with angiotensin converting enzyme inhibitors and beta-blockers than those who did not (P = .019). Ophthalmological adverse events were significantly more frequent in patients who experienced a LVEF-D (P = .006) and the latter did not influence overall-survival (P = .117) or progression-free-survival (P = .297). LVEF-D is a common and easily manageable adverse event due to BRAF and MEKis. Its association with ocular toxicity suggests a close ophthalmological monitoring when LVEF-D occurs.
