Which medical disciplines diagnose and treat melanoma in Europe in 2019? A survey of experts from melanoma centres in 27 European countries.

BACKGROUND AND OBJECTIVES: The incidence of melanoma is increasing. This places significant burden on societies to provide efficient cancer care. The European Cancer Organisation recently published the essential requirements for quality melanoma care. The present study is aimed for the first time to roughly estimate the extent to which these requirements have been met in Europe. MATERIALS AND METHODS: A web-based survey of experts from melanoma centres in 27 European countries was conducted from 1 February to 1 August 2019. Data on diagnostic techniques, surgical and medical treatment, organization of cancer care and education were collected and correlated with national health and economic indicators and mortality-to-incidence ratio (MIR) as a surrogate for survival. Univariate linear regression analysis was performed to evaluate the correlations. SPSS software was used. Statistical significance was set at P < 0.05. RESULTS: The MIR was lower in countries with a high health expenditure per capita and with a higher numbers of general practitioners (GPs) and surgeons (SURG) per million inhabitants. In these countries, GPs and dermatologists (DER) were involved in melanoma detection; high percentage of DER used dermatoscopy and were involved in the follow-up of all melanoma stages; both medical oncologists (ONC) and dermato-oncologists administered systemic treatments; and patients had better access to sentinel lymph node biopsy and were treated within multidisciplinary tumour boards. CONCLUSION: Based on these first estimates, the greater involvement of GPs in melanoma detection; the greater involvement of highly trained DER in dermatoscopy, dermatosurgery, follow-up and the systemic treatment of melanoma; and the provision of ongoing dermato-oncology training for pathologists, SURG, DER and ONC are necessary to provide an optimal melanoma care pathway. A comprehensive analysis of the melanoma care pathway based on clinical melanoma registries will be needed to more accurately evaluate these first insights.

Access to innovative medicines for metastatic melanoma worldwide: Melanoma World Society and European Association of Dermato-oncology survey in 34 countries.

According to data from recent studies from Europe, a large percentage of patients have restricted access to innovative medicines for metastatic melanoma. Melanoma World Society and European Association of Dermato-oncology conducted a Web-based survey on access to first-line recommended treatments for metastatic melanoma by current guidelines (National Comprehensive Center Network, European Society for Medical Oncology [ESMO] and European Organization for Research and Treatment of Cancer/European Association of Dermato-oncology/European dermatology Forum) among melanoma experts from 27 European countries, USA, China, Australia, Argentina, Brazil, Chile and Mexico from September 1st, 2017 to July 1st, 2018. Data on licencing and reimbursement of medicines and the number of patient treated were correlated with the data on health expenditure per capita (HEPC), Mackenbach score of health policy performance, health technology assessment (HTA), ASCO and ESMO Magnitude of clinical benefit scale (ESMO MCBS) scores of clinical benefit and market price of medicines. Regression analysis for evaluation of correlation between the parameters was carried out using SPSS software. The estimated number of patients without access in surveyed countries was 13768. The recommended BRAFi + MEKi combination and anti-PD1 immunotherapy were fully reimbursed/covered in 19 of 34 (55.8%) and 17 of 34 (50%) countries, and combination anti-CTLA4+anti-PD1 in was fully covered in 6 of 34 (17.6%) countries. Median delay in reimbursement was 991 days, and it was in significant correlation with ESMO MCBS (p = 0.02), median market price (p = 0.001), HEPC and Mackenbach scores (p < 0.01). Price negotiations or managed entry agreements (MEAs) with national authorities were necessary for reimbursement. In conclusion, great discrepancy exists in metastatic melanoma treatment globally. Access to innovative medicines is in correlation with economic parameters as well as with healthcare system performance parameters. Patient-oriented drug development, market access and reimbursement pathways must be urgently found.

EVITA-a double-blind, vehicle-controlled, randomized phase II trial of vitamin K1 cream as prophylaxis for cetuximab-induced skin toxicity.

Background: Acne-like skin rash is a frequently occurring adverse event associated with drugs against the epidermal growth factor receptor. This randomized vehicle-controlled study investigated the addition of vitamin K1 cream to doxycycline in patients with metastatic colorectal cancer treated with cetuximab. Patients and methods: Patients receiving first-line cetuximab + FOLFIRI were randomly assigned to prophylactic treatment with doxycylin and vitamin K1 cream or doxycycline and the vehicle. The primary end point of the study was the incidence of grade ≥ 2 skin rash (NCI CTCAE version 4.02) during 8 weeks of skin treatment. Secondary end points comprised skin rash according to a more thorough tripartite skin toxicity score (WoMo), quality of life, efficacy, and compliance. The study had 80% power to show a 20% reduction of the incidence of grade ≥ 2 skin rash. Results: A total of 126 patients were analyzed. The incidence of skin rash grade ≥ 2 was comparable between the arms. Likewise, no difference was seen in the WoMo score with respect to the percentage of skin affected. However, starting in week 5 and increasing over time patients treated with vitamin K1 cream had less severe rash and fewer fissures. Quality of life as well as efficacy and compliance with study medication and anticancer treatment was comparable in both arms. Conclusion: The primary end point of decreasing grade ≥ 2 skin rash was not met. However, using vitamin K1 cream as part of prophylactic treatment decreased the severity of acne-like skin rash according to WoMo, an alternative and more thorough skin toxicity scoring tool.

More than 5000 patients with metastatic melanoma in Europe per year do not have access to recommended first-line innovative treatments.

BACKGROUND: Despite the efficacy of innovative treatments for metastatic melanoma, their high costs has led to disparities in cancer care among different European countries. We analysed the availability of these innovative therapies in Europe and estimated the number of patients without access to first-line recommended treatment per current guidelines of professional entities such as the European Society for Medical Oncology (ESMO), the European Organisation for Research and Treatment of Cancer (EORTC), the European Association of Dermato-Oncology (EADO), and European Dermatology Forum (EDF). MATERIALS AND METHODS: Web-based online survey was conducted in 30 European countries with questions about the treatment schedules from 1st May 2015 to 1st May 2016: number of metastatic melanoma patients, registration and reimbursement of innovative medicines (updated data, as of 1st October 2016), percentage of patients treated and availability of clinical studies and compassionate-use programmes. RESULTS: The recommended BRAF inhibitor (BRAFi) + MEK inhibitor (MEKi) combination was both registered and fully reimbursed in 9/30 (30%) countries, and in 13/30 (43%) (all from Eastern Europe) not reimbursed. First-line immunotherapy with anti-PD1 antibodies was registered and fully reimbursed in 14/30 (47%) countries, while in 13/30 (43%) (all from Eastern Europe) not reimbursed. It was estimated that in Europe 19,600 patients with metastatic melanoma are treated, and 5238 (27%) do not have access to recommended first-line therapy. Significant correlation was found between human development index (HDI, UNDP report 2015), (r = 0.662; p < 0.001), health expenditure per capita (r = 0.695; p < 0.001) and the Mackenbach score of health policy performance (r = 0.765; p < 0.001) with the percentage of patients treated with innovative medicines and a number of reimbursed medicines. CONCLUSIONS: Great discrepancy exists in metastatic melanoma treatment across Europe. It is crucial to increase the awareness of national and European policymakers, oncological societies, melanoma patients' associations and pharma industry.

A phase II study of cetuximab, capecitabine and radiotherapy in neoadjuvant treatment of patients with locally advanced resectable rectal cancer.

BACKGROUND: Neoadjuvant chemoradiotherapy (CRT) reduces local tumor recurrence in locally advanced rectal cancer (LARC). This phase II study assessed neoadjuvant cetuximab with capecitabine-based CRT in LARC. METHODS: Patients with stage II/III LARC received capecitabine 1250 mg/m(2) twice daily for 2 weeks followed by intravenous cetuximab 400 mg/m(2) at week 3, then weekly intravenous 250 mg/m(2) cetuximab plus CRT including capecitabine 825 mg/m(2) twice daily (including weekends during radiotherapy) with radiotherapy of 45 Gy (25 x 1.8 Gy), 5 days a week for 5 weeks. Total mesorectal excision was scheduled 4-6 weeks following completion of CRT. The primary endpoint was pathological complete response (pCR). RESULTS: Thirty-seven patients were eligible for safety and efficacy. TMN staging at baseline was: T4N2, 11%; T3N2, 40%; T2N2, 3%; T3N1, 35%; T2N1, 3% and T3N0 8%. The most common adverse events included, grade 1/2 acneiform skin rash (86%), and grade 3 radiodermatitis, (16%), diarrhea (11%) and hypersensitivity (5%). pCR was achieved in 3 patients (8%). Overall-, T- and N-downstaging rates were 73%, 57% and 81% respectively. Total sphincter preservation rate was 76%, and 53% in 17 patients whose tumors were located within 5 cm from the anal verge. Non-fatal perioperative complications occurred in 13 patients (35%) with delayed wound healing occurring in 6 patients (16%). One death was recorded due to sepsis following colonic necrosis. CONCLUSION: Neoadjuvant cetuximab with capecitabine-based CRT is tolerable in patients with resectable LARC. Whilst the pCR rate was similar to recent reports, a high pathological downstaging rate was achieved.

Management of cutaneous side-effects of cetuximab therapy in patients with metastatic colorectal cancer.

BACKGROUND: Cetuximab is a chimeric human-murine monoclonal antibody against the epidermal growth factor receptor (EGFR). It has shown activities against multiple malignancies in clinical trials. EGFR-inhibitors (EGFRI) often cause skin toxicity, most frequently acneiform eruption. Xerosis, eczema, fissures, teleangiectases, nail changes and paronychia can be seen in some cases, rarely hyperpigmentation. MATERIALS AND METHODS: We reviewed local practice of skin toxicity management during treatment with cetuximab. From November 2005 to January 2007, 31 patients with metastatic colorectal cancer were treated with cetuximab in combination with chemotherapy. They all suffered from acne-like rash. They were followed up for at least 3 months, once per week. Skin toxicity was evaluated according to NCI CTCAE, v3.0. RESULTS: Of 31 patients, six had grade three rash, 16 patients Grade 2 and nine patients Grade 1 acne like rash. Less frequently, pruritus, dry skin, desquamation, hair modification, conjunctivitis, telangiectases, paronychia or fissures were observed. After the first documented cutaneous toxicity, topical use of emollients was started. For Grade 2 rash, we used emollients and topical antibiotics. Therapy with cetuximab was discontinued at Grade 3 until skin reactions resolved. Skin reactions at Grade 3 were generally manageable with emollients, topical and systemic antibiotics. No Grade 4 skin reactions were observed. CONCLUSION: During the treatment with EGFRI, it is necessary to recognize and manage adverse reactions promptly to assure better patient quality of life and allowing continuation of therapy without dose reduction or drug discontinuation.

Soluble tumor necrosis factor receptor I (sTNFRI) as a prognostic factor in melanoma patients in Slovene population.

Tumor necrosis factor alpha (TNF-alpha) and its receptors (TNFRI and TNFRII) which exist in soluble form as a product of cleavage of the extracellular domain of membrane integrated receptors, still rise debate about their importance. It was reported that TNF-alpha has numerous actions in diseases such as inflammation, autoimmunity, infectious diseases, septic shock and many types of cancer [1, 2]. Several authors have reported the significance of sTNFRI level in serum of cancer patients [3, 4]. This study was performed in collaboration with the Institute of Oncology of Slovenia. At least two different mouse monoclonal antibodies (MAbs) against human sTNFRI have been prepared to obtain a sensitive and reliable sandwich ELISA. It was compared with commercially available R&D and Endogen ELISAs for the determination of sTNFRI. Groups of patients with different stages of melanoma and epithelial ovarian carcinoma were tested and their clinical records were reexamined. Levels of sTNFRI were measured and compared with the normal serum levels of sTNFRI.

Serum values of tumour necrosis factor-alpha and of soluble tumour necrosis factor-R55 in melanoma patients.

Tumour necrosis factor-alpha (TNFalpha) is a cytokine with a variety of biological activities, including an effect on tumour growth. The soluble TNF receptor TNF-R55 (sTNF-R55) inhibits TNFalpha functioning. Serum values of TNFalpha and TNF-R55 have been observed in patients with different cancers. To determine the serum values of TNFalpha and its soluble receptors and to investigate the prognostic value of sTNF-R55, we studied the sera of 68 patients with metastatic melanoma, 109 patients with no recurrent disease after surgical removal of melanoma, and 69 healthy controls. At least four different monoclonal antibodies against human TNFalpha and human TNF-R55, respectively, were prepared to obtain sensitive and reliable sandwich enzyme-linked immunosorbent assays. We found that in patients with metastatic melanoma the serum values of sTNF-R55 were significantly higher (2.41 ng/ml; range 0.02 23.0 ng/ml; P < 0.05) than in the melanoma patients without recurrence (0.54 ng/ml; range 0.02-6.25 ng/ml) and healthy controls (0.5 ng/ml; range 0.02 5.0 ng/ml). The sTNF-R55 concentrations increased as the disease progressed. Patients with metastatic melanoma also had significantly higher concentrations of TNFalpha (3.34 ng/ml; range 0.03-30.0 ng/ml; P<0.05) than patients without recurrence (1.24 ng/ml; range 0.02 23.0 ng/ml). Patients with metastatic melanoma, a high sTNF-R55 concentration, a low TNFalpha concentration and a low TNF:sTNF-R55 ratio had the worst prognosis. Low values of sTNF-R55 (<0.6 ng/ml) were associated with favourable response to chemotherapy (P = 0.007). According to our findings, patients with metastatic melanoma have higher values of sTNF-R55 than the controls and melanoma patients without recurrence. sTNF-R55 values higher than 0.6 ng/ml and a TNF:sTNF-R55 ratio lower than 1.5 are unfavourable prognostic factors for response to chemotherapy.
