BACKGROUND: Smoothened (SMO) inhibitors, blocking the sonic hedgehog pathway, have been approved for advanced basal cell carcinoma (aBCC). Safety analyses reveal a high rate of adverse events (AEs) and, most of the time, vismodegib is most commonly stopped when the best overall response is reached. The long-term evolution of aBCC after vismodegib discontinuation is poorly described. The aim of this study is to evaluate the efficacy and safety of the SMO inhibitors (SMOis) available (vismodegib and sonidegib) following rechallenge after complete response (CR) following an initial treatment by vismodegib. MATERIALS AND METHODS: This real-life, retrospective, multicenter and descriptive study is based on an extraction from the CARADERM accredited database, including 40 French regional hospitals, of patients requiring BCC systemic treatment. RESULTS: Of 303 patients treated with vismodegib, 110 achieved an initial CR. The vast majority of these patients (98.2%) stopped vismodegib, notably due to poorly tolerated AEs. The CARADERM database provided a median follow-up of 21 months (13.5-36.0 months) after CR. Of the 110 patients, 48.1% relapsed after a median relapse-free survival of 24 months (13.0-38.0 months). Among them, 35 patients were retreated by an SMOi and the overall response rate was 65.7% (34.3% of CR and 31.4% of partial response). The median duration of retreatment was 6.0 months (4.0-9.5 months). CONCLUSION: Our real-life study, carried out on patients with complex clinical pictures, shows that after treatment discontinuation, 48.1% of patients achieved CR relapse within an average of 24 months (13.0-38.0 months). It emphasized that even though rechallenge can be considered as a therapeutic option, efficacy seems to decrease, suggesting the development of resistance mechanisms.

BACKGROUND: The 'obesity paradox' suggests that higher body mass index (BMI) is associated with better survival values in metastatic melanoma patients, especially those receiving targeted and immune checkpoint inhibitor therapy. Higher BMI is also associated with higher incidences of treatment-related adverse events (TRAEs). This study assesses whether BMI is associated with survival outcomes and adverse events in metastatic melanoma patients with systemic therapy. PATIENTS AND METHODS: This multicentric retrospective study, conducted from 1 March 2013 to 29 April 2019, enrolled adults with unresectable stage III or IV melanoma from the French multicentric prospective cohort-MelBase (NCT02828202). Patients with first-line chemotherapy and targeted and immune therapy were included. Underweight people and those with metastatic mucosal or ocular melanoma were excluded. BMI was categorized using the World Health Organization criteria. Co-primary outcomes included the association between BMI and progression-free survival and overall survival, stratified by treatment type, sex, and age. Secondary endpoints were the association of BMI with overall response and TRAEs. Multivariate analyses were carried out. RESULTS: A total of 1214 patients were analyzed. Their median age was 66.0 years (range, 53-75). Male predominance was observed [n = 738 (61%)]. Most patients received immune checkpoint inhibitor therapy (63%), followed by targeted therapy (32%), and had stage M1c disease (60.5%). Obese patients represented 22% of the cohort. The median follow-up duration was 13.5 months (range, 6.0-27.5). In the pooled analysis, no positive or negative association between BMI and progression-free survival (P = 0.88)/overall survival (P = 0.25) was observed, regardless of treatment type, sex, and age. These results were nonsignificant in the univariate and multivariate analyses. The objective response rate, according to BMI category, did not differ significantly regardless of age. TRAEs were not associated with BMI. CONCLUSION: The observed lack of an association between BMI and survival demonstrates that BMI is not a valuable marker of systemic treatment-related outcomes in metastatic melanoma. Future approaches might focus on the whole-body distribution.

BACKGROUND: Primary cutaneous lymphomas (PCLs) are a heterogeneous group of T-cell (CTCL) and B-cell (CBCL) malignancies. Little is known about their epidemiology at initial presentation in Europe and about potential changes over time. OBJECTIVES: The aim of this retrospective study was to analyse the frequency of PCLs in the French Cutaneous Lymphoma Registry (GFELC) and to describe the demography of patients. METHODS: Patients with a centrally validated diagnosis of primary PCL, diagnosed between 2005 and 2019, were included. RESULTS: The calculated incidence was unprecedently high at 1·06 per 100 000 person-years. The number of included patients increased yearly. Most PCL subtypes were more frequent in male patients, diagnosed at a median age of 60 years. The relative frequency of rare CTCL remained stable, the proportion of classical mycosis fungoides (MF) decreased, and the frequency of its variants (e.g. folliculotropic MF) increased. Similar patterns were observed for CBCL; for example, the proportion of marginal-zone CBCL increased over time. CONCLUSIONS: Changes in PCL frequencies may be explained by the emergence of new diagnostic criteria and better description of the entities in the most recent PCL classification. Moreover, we propose that an algorithm should be developed to confirm the diagnosis of PCL by central validation of the cases.

INTRODUCTION: CARADERM is a French national network that includes patients with rare skin adnexal neoplasms. The present paper describes only the adnexal neoplasm part of this network. The primary objective of CARADERM is to improve medical care for malignant skin adnexal neoplasms. A multidisciplinary review group and a centralized pathological review group have been set up. PATIENTS AND METHODS: A dual network of clinicians and pathologists has been set up. Data are recorded in a secure database. RESULTS: The CARADERM network comprises of 38 clinical centres and 22 pathology centres. Between 2014 and 2017, 1598 patients with an adnexal neoplasm were included. Data of interest were documented in 80% of cases. Median patient age was 72 years. Major histological subtypes were sweat gland carcinomas (50%), hair follicle carcinomas (37.7%), and sebaceous gland carcinomas (9.8%). Surgery was the first-line treatment for 81% of patients, including 76.9% with standard surgical margin analysis, and 5.5% with exhaustive margin analysis. 920 patients (57.6%) underwent a national pathology review process. DISCUSSION: The CARADERM network aims at providing assistance in difficult situations concerning diagnosis and care in skin adnexal neoplasms. Analysis of the CARADERM data should allow the creation of a prognostic classification of these rare neoplasms together with recommendations. A national multidisciplinary consensus exists. Translational and therapeutic research is ongoing. CONCLUSION: The CARADERM network is currently recruiting and more data should lead to improved knowledge of these tumours in the coming years.

PURPOSE: Since 2011, significant progress was observed in metastatic melanoma (MM), with the commercialisation of seven immunotherapies or targeted therapies, which showed significant improvement in survival. In France, in 2004, the cost of MM was estimated at 1634 per patient; this cost has not been re-estimated since. This study provided an update on survival and cost in real-life clinical practice. METHODS: Clinical and economic data (treatments, hospitalisations, radiotherapy sessions, visits, imaging and biological exams) were extracted from the prospective MelBase cohort, collecting individual data in 955 patients in 26 hospitals, from diagnosis of metastatic disease until death. Survival was estimated by the Kaplan-Meier method. Costs were calculated from the health insurance perspective using French tariffs. For live patients, survival and costs were extrapolated using a multistate model, describing the 5-year course of the disease according to patient prognostic factors and number of treatment lines. RESULTS: Since the availability of new drugs, the mean survival time of MM patients has increased to 23.6 months (95%confidence interval [CI] :21.2;26.6), with 58% of patients receiving a second line of treatment. Mean management costs increased to 269,682 (95%CI:244,196;304,916) per patient. Drugs accounted for 80% of the total cost. CONCLUSION: This study is the first that evaluated the impact of immunotherapies and targeted therapies both on survival and cost in real-life conditions. Alongside the introduction of breakthrough therapies in the first and subsequent lines, MM has been associated with a significant increase in survival but also in costs, raising the question of financial sustainability.

As knowledge continues to develop, regular updates are necessary concerning recommendations for practice. The recommendations for the management of melanoma stages I to III were drawn up in 2005. At the request of the Société Française de Dermatologie, they have now been updated using the methodology for recommendations proposed by the Haute Autorité de Santé in France. In practice, the principal recommendations are as follows: for staging, it is recommended that the 7th edition of AJCC be used. The maximum excision margins have been reduced to 2 cm. Regarding adjuvant therapy, the place of interferon has been reduced and no validated emerging medication has yet been identified. Radiotherapy may be considered for patients in Stage III at high risk of relapse. The sentinel lymph node technique remains an option. Initial examination includes routine ultrasound as of Stage II, with other examinations being optional in stages IIC and III. A shorter strict follow-up period (3 years) is recommended for patients, but with greater emphasis on imaging.

OBJECTIVE: To assess the efficacy, safety and acceptability of a new silver poly absorbent dressing (UrgoCleanAg) in the local management of exudative chronic wounds at risk of infection, with inflammatory signs suggesting heavy bacterial load. METHOD: This prospective, multicentre, non-comparative clinical trial was conducted in French hospital wards (dermatology and vascular medicine) or specialised private-practice physicians. Patients were considered at high-risk of infection when presenting with at least three of five selected inflammatory clinical signs, suggesting a heavy bacterial load (pain between two dressing changes, erythema, oedema, malodorous wound and presence of a heavy exudate). They were treated for a maximum period of four weeks, and followed by the physician on a weekly basis, including a clinical examination, area tracings and photographs. The primary efficacy criterion of the trial was the relative wound surface area reduction at the end of the four weeks of treatment. Acceptability was documented by the nursing staff at each dressing change between the weekly evaluations. RESULTS: We recruited 37 patients with chronic wounds. Wound surface area, mostly covered by sloughy tissue, was reduced by 32.5% at the end of the treatment (median value), while the clinical score (maximum value of 5, based on inflammatory clinical signs) decreased from 4.0 to 2.0. Effective debridement properties were documented (62.5% relative reduction of sloughy tissue at week 4; 58.8% of debrided wounds at week 4) and improvement of the periwound skin status was noted (healthy for 28.6% of the patients at week 4 versus 2.7% at baseline). In addition, the tested wound dressing presented a good safety profile associated to a high level of acceptability, noted by both patients and nursing staff. CONCLUSION: These clinical data support that the tested dressing is a credible therapeutic alternative for the management of chronic wounds at risk of infection with inflammatory signs suggesting heavy bacterial load.

BACKGROUND: Monoclonal T-cell receptor (TCR) rearrangement is detected in 57-75% of early-stage mycosis fungoides (MF) at diagnosis. A retrospective study showed molecular residual disease (MRD) in 31% of patients in complete clinical remission (CR) after 1 year of treatment. OBJECTIVES: To confirm the frequency of MRD at 1 year and to determine its prognostic value for further relapse. METHODS: Patients with T1-, T2- or T4-stage MF were prospectively included in this multicentre study. At diagnosis, clinical lesions and healthy skin were biopsied. After 1 year of topical treatment, previously involved skin of patients in CR was biopsied for histology and analysis of TCR-γ gene rearrangement. The results were compared with the clinical status each year for 4 years. RESULTS: We included 214 patients, 133 at T1, 78 at T2 and three at T4 stage. At diagnosis, 126 of 204 cases (61·8%) showed TCR clonality in lesional skin. After 1 year, 83 of 178 patients (46·6%) still being followed up were in CR and 13 of 63 (21%) showed MRD. At 4 years, 55 of 109 patients (50·5%) still being followed up were in CR and 44 of 109 (40·4%) were in T1 stage. MRD did not affect clinical status at 4 years (CR vs. T1/T2, P = 1·0; positive predictive value 36·4%; negative predictive value 67·6%). CONCLUSIONS: T-cell clonality at diagnosis and MRD at 1 year are not prognostic factors of clinical status at 4 years.

BACKGROUND: Stage III melanoma represents a borderline situation regarding the potential curability of this potentially aggressive cancer and consequently, regional lymph node metastases (RLNM) are a major challenge for melanoma management. OBJECTIVE: To describe the management of melanoma with RLNM as practised in France in 2008 and compare results with previous data from 2004, considering that new French recommendations were published in 2005. METHODS: Retrospective population-based study in five regions of France totalling 8.3 million inhabitants, targeting all incident cases of RLNM diagnosed in 2008. Questionnaires were mailed to physicians to identify cases and collect data, with verification by cancer registries for cases diagnosed concomitantly with the primary tumour using sentinel lymph node biopsies (SLNB). RESULTS: Data were collected for 101 patients in 2008, and compared to 89 cases treated in 2004. Palpation by a dermatologist was the most common circumstance of diagnosis of RLNM in 2008 (36%), followed by SLNB (29%), self-palpation by the patient (16%) and lymph node ultrasonography (6%), without significant modification from 2004. After lymphadenectomy an adjuvant therapy was proposed in 62% of cases, mainly consisting in high-dose interferon (HD-IFN) (80%). Overall, HD-IFN was proposed in 49% of cases, but effectively started in only 40% of cases after being proposed, and prematurely withdrawn in 28%, showing major changes as compared with 2004 (33%, 77% and 67%, respectively, P < 0.05). Adjuvant chemotherapy was not proposed to any patients in 2008, compared to 29% in 2004. Surveillance procedures included medical imaging less often in 2008 (76%) than in 2004 (92%) (P = 0.004), but more often included FDG-PET (23% vs. 12%, P = 0.09). CONCLUSION: Overall, actual practice was in accordance with French recommendations. The main developments from 2004 to 2008 were the disappearance of adjuvant chemotherapies and a more accurate selection of patients for adjuvant interferon.

BACKGROUND: Little data are available concerning the role of general practitioners (GPs) in the diagnosis of melanoma. OBJECTIVES: To evaluate the actual role of GPs in a population-based study covering five regions of France and 8·2 million inhabitants. MATERIALS AND METHODS: A survey of cancer registries and pathology laboratories, and questionnaires to practitioners were used to identify incident melanomas in 2008, and evaluate characteristics of patients (age, sex, area of residence, social isolation), tumours (Breslow, ulceration, location, histological type), and GPs (training, conditions of practice), and their influence on patterns of diagnosis and Breslow thickness. RESULTS: Among 898 melanomas, 376 (42%) were first diagnosed in a general practice setting (GP group). Breslow thickness was much higher in the GP group than in other melanomas (median: 0·95 vs. 0·61 mm, P < 0·0001). Multivariate analysis identified an older age, lower limb location, nodular subtype and Breslow thickness as factors associated with the GP group. Within this group, 52·5% of melanomas were detected by patients (median Breslow thickness: 1·30 mm) and 47·5% by GPs (median Breslow thickness: 0·80 mm, P = 0·0009), including 8% during a systematic full-body skin examination. Previous GP training on melanoma was associated with active detection by GPs. Male sex and social isolation of patients were associated with thicker melanomas, whereas active detection by GPs was associated with thinner CMs. CONCLUSIONS: GPs play a key role in melanoma diagnosis in France, but still frequently detect thick tumours. Increasing awareness and training of GPs and focusing attention on male and/or socially isolated patients should help to improve early detection of melanoma.

BACKGROUND: Sentinel lymph node (SLN) biopsy for patients with cutaneous melanoma has become a routine procedure. Its purpose is to confirm the potential presence of micrometastases in the first lymph node basin. Therefore, staging of the melanoma can be determined. Somehow, only few studies assess the morbidity of this procedure. Our study was performed in order to list and analyze SLN biopsy-related complications in melanoma-affected patients. PATIENTS AND METHODS: This mono-institutional, retrospective study enrolled patients, operated on from May 2001 until August 2008, who had undergone SLN biopsy that found no metastatic colonization. Patients with positive SLN biopsy underwent subsequent completion lymph node dissection (CLND) and, therefore, were not included in this study. Thus, CLND-related complications did not interfere with SLN biopsy-related ones. Median follow-up was 19 months. RESULTS: One hundred and twenty-seven patients, 58 men and 69 women were evaluated. Nine patients (7,1%) were diagnosed with one complication. We noticed seven early complications occurring during the first month (four seromas, one lymphocele, one infection with dehiscence of wound, one deep veinous thrombosis) and two late complications occurring beyond this period (one neuroma, one cicatricial bridle). Four (44%) among these complications arose in the groin. CONCLUSION: SLN biopsy is known as a simple and minimally invasive surgical technique. Somehow, some potentially severe complications may arise. These must be clearly explained to obtain the patient's informed consent prior to surgery.

BACKGROUND: The treatment of stage I Merkel cell carcinoma (MCC) usually includes wide local excision (WLE) combined with irradiation of the tumor bed (ITB). No randomized study has ever been conducted in MCC. The purpose of this study was to assess the efficacy and safety of prophylactic adjuvant radiotherapy on the regional nodes. PATIENTS AND METHODS: In this randomized open controlled study, patients for a stage I MCC treated by WLE and ITB were randomly assigned to regional adjuvant radiotherapy versus observation. Overall survival (OS) and probability of regional recurrence (PRR) were primary end points. Progression-free survival (PFS) and tolerance of irradiation were secondary end points. RESULTS: Eighty-three patients were included before premature interruption of the trial, due to a drop in the recruitment mainly due to the introduction of the sentinel node dissection in the management of MCC. No significant improvement in OS (P = 0.989) or PFS (P = 0.4) could be demonstrated after regional irradiation, which, however, significantly reduced the PRR (P = 0.007) with 16.7% regional recurrence rate in the observation arm versus 0% in the treatment arm. The treatment was well tolerated. CONCLUSION: The adjuvant regional irradiation significantly decreased the PRR in MCC, but benefit in survival could not be demonstrated.

INTRODUCTION: Sentinel lymph node (SLN) biopsy is frequently discussed in the management of cutaneous melanoma, especially in head and neck localizations where SLN biopsy is much more demanding. The benefits of SLN protocol are not proved yet. The aim of our study was to present our experience of SLN biopsy in head and neck cutaneous melanoma. PATIENTS AND METHODS: This retrospective study included all patients managed for head and neck malignant melanoma from 2002 to 2006. We reviewed the technique, implementation and difficulties of the procedure, postoperative outcome, and complications. RESULTS: Nineteen patients were included. An average of 2.2 lymph nodes were localized per patient using lymphoscintigraphy. Biopsy was impossible for one patient because the deep spinal node was not found. An average of 1.2 nodes was biopsied per patient. One patient presented with micrometastases. Another presented with lymphorrhea. DISCUSSION: Sentinel node biopsy is widely performed in the management of cutaneous melanoma but remains an option for these indications in the last update of the French Society of Dermatology. SLN biopsy is difficult to implement because of the complexity of head and neck lymphatic system.

AIMS: To provide recommendations for the treatment of cutaneous B-cell lymphomas (CBCL). METHODS: Literature review and expert opinions from the French Cutaneous Lymphoma Study Group. RESULTS: Diagnosis of marginal zone BCL (MZ BCL), centrofollicular BCL (CF BCL) or cutaneous large B-cell lymphoma, leg type (CLBCL, LT) is based on combination of clinical signs and histopathological features, together with B-cell clonality analyses whenever possible. Staging relies on straightforward laboratory examinations and imaging, completed in selected cases with bone marrow biopsy. Treatment may be topical, including excision, curative radiotherapy (30Gray) or adjunctive/low dose (4Gray) radiotherapy, topical corticosteroids, interferon or intralesional rituximab; or systemic, using chemotherapy and/or intravenous rituximab. For indolent forms of the disease (MZ CBCL and CF CBCL), curative (30Gray) may be given as first-line treatment in patients with localized lesions or few scattered skin lesions. For more numerous slow-growing lesions with a low tumour burden, simple monitoring with adjunctive ad hoc local treatment of individual lesions is acceptable. For multiple growing lesions, systemic rituximab or chlorambucil may be proposed. Polychemotherapy should only be used for progressive forms unresponsive to previous therapies. CLBCL LT forms are more aggressive and occur in older subjects. These lymphomas are best treated with age-adapted combinations of polychemotherapies and rituximab. CONCLUSION: Appropriate clinical trials are still needed to strengthen the levels of evidence of current recommendations.

BACKGROUND: Although metastatic melanoma occurrence during pregnancy challenges the physician in several ways, only a few studies have been published. OBJECTIVES: Our aim was to investigate therapeutic management together with maternal and fetal outcomes in pregnant women with advanced melanoma. METHODS: A French national retrospective study was conducted in 34 departments of Dermatology or Oncology. All patients with American Joint Committee on Cancer (AJCC) stage III/IV melanoma diagnosed during pregnancy were included. Data regarding melanoma history, pregnancy, treatment, delivery, maternal and infant outcomes were collected. RESULTS: Twenty-two women were included: 10 AJCC stage III and 12 stage IV. Abortion was performed in three patients. Therapeutic abstention during pregnancy was observed in three cases, 14 patients underwent surgery, four patients received chemotherapy and one patient was treated with brain radiotherapy alone. The median gestational age was 36 weeks amenorrhoea. Neither neonatal metastases nor deformities were observed. Placenta metastases were found in one case. Among 18 newborns, 17 are currently alive (median follow up, 17 months); one died of sudden infant death. The 2-year maternal survival rates were 56% (stage III) and 17% (stage IV). CONCLUSIONS: Faced with metastatic melanoma, a majority of women chose to continue with pregnancy, giving birth, based on our samples, to healthy, frequently premature infants. Except during the first trimester of pregnancy, conventional melanoma treatment was applied. No serious side effect was reported, except one case of miscarriage after surgery. Mortality rates do not suggest a worsened prognosis due to pregnancy but larger prospective controlled studies are necessary to assess this specific point.
