RESUMEN

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.

RESUMEN

BACKGROUND: Programmed cell death protein 1 (PD-1) blocking monoclonal antibodies improve the overall survival of patients with advanced melanoma but the optimal duration of treatment has not been established. PATIENTS AND METHODS: This academic real-world cohort study investigated the outcome of 185 advanced melanoma patients who electively discontinued anti-PD-1 therapy with pembrolizumab (N = 167) or nivolumab (N = 18) in the absence of disease progression (PD) or treatment limiting toxicity (TLT) at 14 medical centres across Europe and Australia. RESULTS: Median time on treatment was 12 months (range 0.7-43). The best objective tumour response at the time of treatment discontinuation was complete response (CR) in 117 (63%) patients, partial response (PR) in 44 (24%) patients and stable disease (SD) in 16 (9%) patients; 8 (4%) patients had no evaluable disease (NE). After a median follow-up of 18 months (range 0.7-48) after treatment discontinuation, 78% of patients remained free of progression. Median time to progression was 12 months (range 2-23). PD was less frequent in patients with CR (14%) compared with patients with PR (32%) and SD (50%). Six out of 19 (32%) patients who were retreated with an anti-PD-1 at the time of PD obtained a new antitumour response. CONCLUSIONS: In this real-world cohort of advanced melanoma patients discontinuing anti-PD-1 therapy in the absence of TLT or PD, the duration of anti-PD-1 therapy was shorter when compared with clinical trials. In patients obtaining a CR, and being treated for >6 months, the risk of relapse after treatment discontinuation was low. Patients achieving a PR or SD as best tumour response were at higher risk for progression after discontinuing therapy, and defining optimal treatment duration in such patients deserves further study. Retreatment with an anti-PD-1 at the time of progression may lead to renewed antitumour activity in some patients. CLINICAL TRIAL REGISTRATION: NCT02673970 (https://clinicaltrials.gov/ct2/show/NCT02673970?cond=melanoma&cntry=BE&city=Jette&rank=3).

RESUMEN

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.

RESUMEN

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.

RESUMEN

Distant metastases are the main cause of death in patients with medullary thyroid cancer (MTC). These 21 recommendations focus on MTC patients with distant metastases and a detailed follow-up protocol of patients with biochemical or imaging evidence of disease, selection criteria for treatment, and treatment modalities, including local and systemic treatments based on the results of recent trials. Asymptomatic patients with low tumor burden and stable disease may benefit from local treatment modalities and can be followed up at regular intervals of time. Imaging is usually performed every 6-12 months, or at longer intervals of time depending on the doubling times of serum calcitonin and carcinoembryonic antigen levels. Patients with symptoms, large tumor burden and progression on imaging should receive systemic treatment. Indeed, major progress has recently been achieved with novel targeted therapies using kinase inhibitors directed against RET and VEGFR, but further research is needed to improve the outcome of these patients.

RESUMEN

PURPOSE: To compare health-related quality of life (HRQoL) and side-effects in patients with high-risk melanoma participating in a randomised phase III trial of adjuvant interferon alfa-2b (IFN). PATIENTS AND METHODS: A total of 855 patients with histologically verified resected cutaneous melanoma in AJCC stage IIb (T4 N0 M0) or stage III (Tx N1-3 M0) were randomised to: Arm A: observation only (n = 284); Arm B: 1-year treatment: induction: IFN alfa-2b, 10 MU (flat dose), SC, 5 days/week, 4 weeks, maintenance: IFN alfa-2b, 10 MU (flat dose), SC, 3 days/week for 12 months (n = 285); or Arm C: 2 years of same treatment as Arm B. HRQoL was assessed using The European Organisation for Research and Treatment of Cancer Core Questionnaire (EORTC QLQ-C30) before randomisation and at 8 pre-defined time-points during 2 years. IFN-related side-effects were assessed by a study-specific questionnaire. RESULTS: > 80% of eligible patients returned questionnaires at the different assessment points. Statistically significant interactions between randomisation arm and time after randomisation were found for almost all EORTC QLQ-30 variables. While patients in Arm A improved or remained at baseline levels; patients in Arms B and C reported decreased functioning and quality of life, and an increase in side-effects during their treatment. Patients in Arm B improved after the 12th month assessment, when IFN treatment was scheduled to end, to the 16th month assessment (p < 0.001). The same pattern of improvement was found for 5 of 7 interferon-related side-effects. CONCLUSION: A significant negative impact on HRQoL of IFN treatment was demonstrated, however the impact were reversible when treatment was stopped.

RESUMEN

Chemotherapy, biological agents or combinations of both have had little impact on survival of patients with metastatic melanoma. Advances in understanding the genetic changes associated with the development of melanoma resulted in availability of promising new agents that inhibit specific proteins up-regulated in signal cell pathways or inhibit anti-apoptotic proteins. Sorafenib, a multikinase inhibitor of the RAF/RAS/MEK pathway, elesclomol (STA-4783) and oblimersen (G3139), an antisense oligonucleotide targeting anti-apoptotic BCl-2, are in phase III clinical studies in combination with chemotherapy. Agents targeting mutant B-Raf (RAF265 and PLX4032), MEK (PD0325901, AZD6244), heat-shock protein 90 (tanespimycin), mTOR (everolimus, deforolimus, temsirolimus) and VEGFR (axitinib) showed some promise in earlier stages of clinical development. Receptor tyrosine-kinase inhibitors (imatinib, dasatinib, sunitinib) may have a role in treatment of patients with melanoma harbouring c-Kit mutations. Although often studied as single agents with disappointing results, new targeted drugs should be more thoroughly evaluated in combination therapies. The future of rational use of new targeted agents also depends on successful application of analytical techniques enabling molecular profiling of patients and leading to selection of likely therapy responders.

RESUMEN

Adequate surgical management of primary melanoma and regional lymph node metastasis, and rarely distant metastasis, is the only established curative treatment. Surgical management of primary melanomas consists of excisions with 1-2 cm margins and primary closure. The recommended method of biopsy is excisional biopsy with a 2 mm margin and a small amount of subcutaneous fat. In specific situations (very large lesions or certain anatomical areas), full-thickness incisional or punch biopsy may be acceptable. Sentinel lymph node biopsy provides accurate staging information for patients with clinically unaffected regional nodes and without distant metastases, although survival benefit has not been proved. In cases of positive sentinel node biopsy or clinically detected regional nodal metastases (palpable, positive cytology or histopathology), radical removal of lymph nodes of the involved basin is indicated. For resectable local/in-transit recurrences, excision with a clear margin is recommended. For numerous or unresectable in-transit metastases of the extremities, isolated limb perfusion or infusion with melphalan should be considered. Decisions about surgery of distant metastases should be based on individual circumstances. Radiotherapy is indicated as a treatment option in select patients with lentigo maligna melanoma and as an adjuvant in select patients with regional metastatic disease. Radiotherapy is also indicated for palliation, especially in bone and brain metastases.

RESUMEN

Immunotherapy of metastatic melanoma consists of various approaches leading to specific or non-specific immunomodulation. The use of FDA-approved interleukin (IL)-2 alone, in combination with interferon alpha, and/or with various chemotherapeutic agents (biochemotherapy) is associated with significant toxicity and poor efficacy that does not improve overall survival of 96% of patients. Many studies with allogeneic and autologous vaccines have demonstrated no clinical benefit, and some randomised trials even showed a detrimental effect in the vaccine arm. The ongoing effort to develop melanoma vaccines based on dendritic cells and peptides is driven by advances in understanding antigen presentation and processing, and by new techniques of vaccine preparation, stabilisation and delivery. Several agents that have shown promising activity in metastatic melanoma including IL-21 and monoclonal antibodies targeting cytotoxic T lymphocyte-associated antigen 4 (anti-CTLA-4) or CD137 are discussed. Recent advances of intratumour gene transfer technologies and adoptive immunotherapy, which represents a promising although technically challenging direction, are also discussed.

RESUMEN

BACKGROUND: Central nervous system (CNS) metastases develop in nearly half of patients with advanced melanoma and in 15-20% CNS is the first site of relapse. Median overall survival is short, ranging from two to four months, and one-year survival rate is only 10-15%. THA has been shown to have both anti-angiogenetic and immuno-modulating effects. TMZ is an oral alkylating agent with an excellent oral bioavailability and it is highly lipophillic with an ability to penetrate the blood-brain barrier. TMZ and THA in combination were tested in patients with brain metastases from malignant melanoma. METHODS: Between June 2004 and February 2007 patients with measurable metastatic melanoma in progression and PS ≤ 1 received TMZ in a dose of 150 mg/m(2) qd for seven days, followed by seven days off therapy and THA in 200 mg qd, both orally administered. Concomitant treatment with steroids was allowed. PBMCs were collected from the last 14 consecutive patients for evaluation of immune parameters. RESULTS: Forty screened patients were eligible and evaluable for response, and 39 were evaluable for toxicity. 25 patients had asymptomatic and 15 symptomatic brain metastases. The toxicity was primarily grade 1-2 with no grade 4 or treatment-related deaths. Four patients had thromboembolic events grade 3. One patient obtained a CR and five a PR in the CNS, while two had CR and four had PR outside CNS. Overall response rate was 17.5%. We found a significant positive correlation between lymphopenia and objective response. CONCLUSIONS: The combination treatment was well tolerated but with more frequent thromboembolic events compared to single drug TMZ or THA. The treatment demonstrated activity in CNS as well as outside CNS. The correlation between lymphopenia and objective response needs further investigation.

RESUMEN

The Postgraduate Hospital Educational Environment Measure (PHEEM) has been translated into Danish and then validated with good internal consistency by 342 Danish junior and senior hospital doctors. Four of the 40 items are culturally dependent in the Danish hospital setting. Factor analysis demonstrated that seven items are interconnected. This information can be used to shorten the instrument by perhaps another three items.

RESUMEN

We aimed to create a prognostic model in metastatic melanoma based on independent prognostic factors in 321 patients receiving interleukin-2 (IL-2)-based immunotherapy with a median follow-up time for patients currently alive of 52 months (range 15-189 months). The patients were treated as part of several phase II protocols and the majority received treatment with intermediate dose subcutaneous IL-2 and interferon-alpha. Neutrophil and monocyte counts, lactate dehydrogenase (LDH), number of metastatic sites, location of metastases and performance status were all statistically significant prognostic factors in univariate analyses. Subsequently, a multivariate Cox's regression analysis identified elevated LDH (P<0.001, hazard ratio 2.8), elevated neutrophil counts (P=0.02, hazard ratio 1.4) and a performance status of 2 (P=0.008, hazard ratio 1.6) as independent prognostic factors for poor survival. An elevated monocyte count could replace an elevated neutrophil count. Patients were assigned to one of three risk groups according to the cumulative risk defined as the sum of simplified risk scores of the three independent prognostic factors. Low-, intermediate- and high-risk patients achieved a median survival of 12.6 months (95% confidence interval (CI), 11.4-13.8), 6.0 months (95% CI, 4.8-7.2) and 3.4 months (95% CI, 1.2-5.6), respectively. The low-risk group encompassed the majority of long-term survivors, whereas the patients in the high-risk group with a very poor prognosis should probably not be offered IL-2-based immunotherapy.

RESUMEN

BACKGROUND: Experimental data had suggested a synergistic effect of histamine with interleukin-2 (IL-2) and interferon-alpha (IFN-alpha). PATIENTS AND METHODS: Forty-one patients with metastatic melanoma received IL-2 9 MU subcutaneously (s.c.) twice daily on days 4-8 and 25-29, and once daily on days 11-15 and 32-36. IFN-alpha-2b was given as 5 MU s.c. on days 1-3 and then daily to day 43. Histamine 1 mg s.c. was administered twice daily, following IL-2 and IFN injections starting on day 4. Efficacy and toxicity were compared with those of 42 patients included on exactly the same criteria and receiving the same regimen but without histamine. RESULTS: Two patients achieved a partial response (PR) for an objective response rate of 5% [95% confidence interval (CI) 1% to 17%]. Median overall survival was 7.8 months (95% CI 6.4-9.1). In the control group, two complete responses and one PR were achieved. Median overall survival was 7.1 months (95% CI 5.4-8.9). CONCLUSIONS: This IL-2 and IFN regimen was well tolerated on an outpatient basis. However, the applied regimen cannot be recommended because of the low clinical efficacy. Histamine did not add efficacy or toxicity in combination with this moderate-dose schedule of IL-2 and IFN.

RESUMEN

In this phase II study 37 patients with metastatic melanoma were treated with cisplatin 100 mg/m2 every three weeks and interferon alpha-2b 10 MU subcutaneously three times weekly; 125 cycles were administered. Thirty-four patients were evaluable for response and all 37 patients were assessable for toxicity. Four patients stopped treatment with cisplatin because of severe nephrotoxicity, and six patients stopped therapy because of other toxicities. Response rate was 6/34 = 18% (95%) CI (confidence interval): 7%-35%). One patient reached complete response lasting 27+ months. Five patients obtained partial responses with a median duration of response of 7 months (range 5-15+ ). Median time to progression was 2.3 months (range 1-27+). Median survival was 5 months (range 1-27+). We conclude that the combination of high-dose cisplatin 100 mg/m2 and interferon alpha-2b is associated with unacceptable toxicity. Haematological toxicity and nephrotoxicity were pronounced and the response rate was meagre and not encouraging.

RESUMEN

PURPOSE: This study focuses on the clinical characteristics of patients with osteoradionecrosis (ORN) of the jaws and on the relation between the extent of the ORN and the field of irradiation. PATIENTS AND METHODS: The study group consisted of 80 patients referred for treatment of ORN. Charts of the extent of ORN, based on panoramic radiographs, were drawn by the clinical investigator and compared with charts of the field of irradiation drawn by the oncologists. Also recorded was diagnosis of the lesion, stage, location, treatment schedule, and period and dose of irradiation. Also documented were various potential initiating factors for ORN. RESULTS: Smoking habits of ORN patients were similar to those of other patients with head and neck cancer. A new primary tumor or a recurrence was diagnosed in 10% of the patients at the time of ORN. Only 3 patients had received accumulated doses of less than 60 Gy. More than half of the cases were initiated by removal of teeth; however, one third occurred spontaneously. ORN developed within the first 3 years in 74%; but ORN can emerge on a traumatic basis for an infinite number of years after radiation therapy. Widespread ORN may be symptomless apart from a discrete dehiscense of the oral mucosa. The predilection site for ORN is the mandibular molar region. All cases of ORN but 1 were found in the field of radiation. CONCLUSION: Because many ORN case are symptomless, more focus on mucosal dehiscence in the follow-up after radiation therapy is advocated in an effort to detect ORN at an early stage. The consequence of practically all ORN cases being located in the field of irradiation, together with tooth removal frequently being the initiating factor, should lead to a more aggressive preirradiation approach to dental pathology located within the field of radiation.

The efficacy of combined endocrine therapy with tamoxifen (TAM), aminoglutethimide (AG), and hydrocortisone (H) or tamoxifen and fluoxymesterone (FLU) was evaluated against treatment with tamoxifen alone in 311 patients above 65 years of age with a first recurrence of a metastatic breast cancer. A total of 279 patients were eligible. The response rates were assessed for 258 fully evaluable patients and were the following for the TAM (N = 94), the TAM+AG+H (N = 83), and the TAM+FLU (N = 81) groups, respectively, PR: 14, 18, and 21%, and CR: 20, 11, and 23%. The overall response rates are not statistically different (p = 0.30). The 95% CL of difference in response rates for TAM vs. TAM+AG+H are -9-19% and for TAM vs. TAM+FLU -4-25%. Time to treatment failure was comparable with median values of 9.2, 7.7, and 9.2 months in the TAM, TAM+AG+H, and TAM + FLU group, respectively (p = 0.17). The corresponding figures for survival are median times of 22.0, 24.1, and 21.1 months with a p-value of 0.62. Toxicity was more pronounced in both the combined treatment groups, and could in most instances be attributed to treatment with either AG+H or FLU. Currently, new specific aromatase inhibitors with lesser toxicity than AG are being evaluated in combination with TAM for treatment of primary and metastatic breast cancer. In conclusion, the simultaneous use of TAM and AG +H or FLU does not seem to improve the therapeutic efficacy in elderly postmenopausal patients with metastatic disease. So far, combined endocrine therapy in this group of patients should only be used in the context of clinical trials.

RESUMEN

A retrospective review was conducted on 13 patients with esthesioneuroblastoma (ENB), treated at our institution from 1977 to 1997. According to the Kadish classification, one patient was in stage A, 5 patients were classified as stage B and 7 patients were in stage C. Five-year disease-specific survival was found to be 51%. Forty-six percent of the patients experienced relapse and despite intensive salvage therapy, median survival after recurrences was only 12 months. This indicates the need for good primary control in local as well as distant disease. The role of pre- versus postoperative radiotherapy to secure good local control is discussed and compared with the literature, and treatment guidelines are proposed. The tumours were graded according to the Hyams' classification and its importance as a prognostic factor is briefly discussed.

RESUMEN

A phase II study was performed to evaluate the efficacy of cisplatin combined with interleukin-2 and interferon-alpha2b administered subcutaneously to patients with metastatic malignant melanoma (MMM). Between April 1994 and January 1999, 87 patients with MMM and a WHO performance status of < or = 2 were entered into the study. The first 42 patients had prophylactic cimetidine; the other 45 patients did not. An overall response rate of 27% was achieved in the 82 patients evaluable for response. The median response duration was 7.0 months (range 4.4-29.0 months). The median survival for all patients was 10.1 months (range 0.4-64.9+ months). Toxicity was substantial but generally manageable and usually reversed on dose reduction or temporary interruption of treatment. Two patients (2%) died of treatment-related toxicity. No difference in response or survival was seen in the patients treated with or without cimetidine. In multivariate analysis, lactate dehydrogenase level (P < 0.001), number of metastatic sites (P = 0.014) and performance status (P = 0.035) was shown to be independent prognostic factors for survival. This high dose interleukin-2 subcutaneous regimen resulted in a small fraction of long-term survivors. The response and survival results were not superior to other studies using lower and less toxic interleukin-2 doses.

RESUMEN

From 1978 to 1992, 66 patients (32 women and 34 men) were treated for carcinoma of the nasal vestibule at Odense University Hospital. The treatment was radiotherapy (41 patients), surgery (13 patients) or a combination of the two modalities (12 patients). Twenty-one patients (32%) developed recurrence. Of these, 17 (81%) were diagnosed within the first two years of follow up. The recurrence rate was found to be correlated to the anatomic site of the tumour-origin; septal site of origin meant higher risk of recurrence. Five-year disease specific and crude survival of all patients were 87.0% and 58.5%, respectively. Several variables (sex, age, anatomic site of origin, Wang-classification, tumour volume and regional lymphnode metastases at time of diagnosis) were evaluated as possible prognostic indicators. In univariate analysis, regional lymph node metastases at the time of diagnosis and anatomic site of origin of the tumour showed a significant influence on survival. In multivariate analysis, septal origin of primary tumour was a significant, independent predictive factor of recurrence and the presence of lymph node metastases at the time of diagnosis showed to be a highly significant prognosticator of both disease specific and crude survival (p < 0.0001). We conclude that patients with primary lymph node metastases and septal location of primary tumour need intensive primary treatment and close follow up.
