Follow-up of a National Cohort of Melanoma Stage IV and Unresectable Stage III Patients

2016-07-12 00:53:21 | BioPortfolio

Summary

Prevention of melanoma can be efficient but mortality remains unchanged and 15 to 20% of patients still die from melanoma. Indeed metastatic melanoma is a heterogeneous highly and multiple mutations driven cancer. Significant survival benefit was demonstrated since 2011 with anti-CTLA4, programmed death-1 (anti PD1) antibodies, B-Raf proto-oncogene, serine/threonine kinase (BRAF) and MAP-ERK kinase (MEK) inhibitors. Future improvement of advanced melanoma prognosis will rely on clinico-epidemiological studies and on biological studies aiming to validate and identify new prognostic and predictive factors based upon clinico-epidemiological and histological data, genomic host and tumor alterations, tumor microenvironment characteristics, individual immunological profile and functional imaging. In the context of marketing of costly innovative molecules prospective collection of economic data on treatment and toxicity are required. Large biobanks collecting data from cohorts of advanced melanoma are mandatory for such projects.

MELBASE is a French prospective national cohort enrolling advanced melanoma patients whose objectives are :

- To provide an annual instrument panel with a descriptive and correlative analysis of patients with advanced melanoma in France including epidemiological, clinical and biological socio-economic characteristics

- to validate and identify new clinical, epidemiological, and biological prognostic factors such as genomic host and tumor alterations, tumor microenvironment characteristics, individual immunological profile in advanced melanoma.

- to evaluate the risk-benefit, the impact on treatment on patient quality of life, the management cost of patients treated with the validated and future treatments of metastatic melanoma. The project also aims to define predictive biomarkers of response and toxicity including pharmacogenetics and tumor genetics alterations, tumor microenvironment characteristics, individual immunological profile.

Patients with unresectable stage III or stage IV melanoma will be enrolled prospectively for 1 year with a 3 years follow-up (a total of 1000 patients will be enrolled) from 26 French centers A database of clinical monitoring of metastatic patients will be established and associated with a virtual tumor bank. This national database will be issued from the use of biological, clinical and imaging databases already available in the centers and optimized for this project; this database will also results from the interaction with the French national cancer institute (INCa) genotyping platform.

Description

Melanoma is the first cancer in terms of increasing frequency in France. Prevention can be efficient in detecting melanoma with good prognosis but mortality remains unchanged and 15 to 20% of patients still die from melanoma. Indeed metastatic melanoma is a heterogeneous highly and multiple mutations driven cancer which is highly resistant to conventional treatments. Significant survival benefit was demonstrated since 2011 with anti-CTLA4 and anti PD1 antibodies and BRAF and MEK inhibitors .Future improvement of advanced melanoma prognosis will rely on clinico-epidemiological studies and on biological studies aiming to validate and identify new prognostic and predictive factors based upon clinico-epidemiological and histological data, genomic host and tumor alterations, tumor microenvironment characteristics, individual immunological profile and functional imaging. In the context of marketing of costly innovative molecules in this indication, an assessment of resource consumption is required, with prospective collection of economic data on treatment and toxicity. Large biobanks collecting data from cohorts of advanced melanoma are mandatory for such projects.

The "Groupe Multidisciplinaire Français du Mélanome cutané" (GMFmel) group plans to build a prospective cohort enrolling advanced melanoma patients, MELBASE. MELBASE is a French national multidisciplinary project whose objectives are :

- To provide an annual instrument panel with a descriptive and correlative analysis of patients with advanced melanoma in France including epidemiological, clinical and biological socio-economic characteristics

- to validate and identify new clinical, epidemiological, and biological prognostic factors such as genomic host and tumor alterations, tumor microenvironment characteristics, individual immunological profile in advanced melanoma.

- to evaluate the risk-benefit, he impact on treatment on patient quality of life, the management cost of patients treated with the validated and future treatments of metastatic melanoma. If possible, cost-effectiveness ratios wil be calculated either in all treated patients or in selected populations of patients (based on clinical or biological criteria, like biomarkers), in order to identify the populations in which these new therapeutics will be the more cost-effective. The project also aims to define predictive biomarkers of response and toxicity including pharmacogenetics and tumor genetics alterations, tumor microenvironment characteristics, individual immunological profile.

Patients with unresectable stage III or stage IV melanoma will be enrolled prospectively for 1 year with a 3 years follow-up (a total of 1000 patients will be enrolled) from 26 French centers.

A database of clinical monitoring of metastatic patients will be established and associated with a virtual tumor bank. The database will be issued from the use of biological, clinical and imaging databases already available in the centers and optimized for this project; this database will also results from the interaction with the INCa genotyping platform. The information collected in MELBASE will include clinical constitutional factors, factors linked to primary melanoma, factors linked to previous lymph node involvement, tumor kinetics informations, "American Joint Committee on Cancer" (AJCC) stage at inclusion and after various therapeutic intervention, serological markers, metastatic tumor genotyping (one or more sites, one or more time points), therapeutic interventions (medical, surgical, radiotherapy and palliative strategies) with evaluation of response, tolerance, medical direct costs, impact on quality of life, psycho-socio-economic variables including a specific a specific questionnaire, date of death, date of latest news.

MELBASE will comprise a virtual Tumor bank collecting samples from the same unresectable stage III and stage IV patients enrolled in the study. These samples will be available in the Biological Resource Centers (CRB) of each participating center and will consist of the primary melanoma (mostly paraffin embedded), metastatic sample (s)(paraffin embedded and frozen) from at least 1 site at inclusion and during evolution, particularly before treatment modification if clinically required, DNA from peripheral blood mononuclear cells, plasma sampled at inclusion and every 6 months during 3 years.

The computer data processing will therefore ensure the role of a data warehouse to generate clinico-epidemiological reports and analysis and that of a virtual catalog of biological material. MELBASE project will be consistent with the ethical chart of the hospital tumor banks published by Inca and will be managed by a chart ensuring each participating center management autonomy and availability of the data put into the database and made available. A multidisciplinary scientific advisory board will identify research priorities based on clinical practice and scientific knowledge.

Medical and Biotech [MESH] Definitions

An unpigmented malignant melanoma. It is an anaplastic melanoma consisting of cells derived from melanoblasts but not forming melanin. (Dorland, 27th ed; Stedman, 25th ed)

Tumors of the iris characterized by increased pigmentation of melanocytes. Iris nevi are composed of proliferated melanocytes and are associated with neurofibromatosis and malignant melanoma of the choroid and ciliary body. Malignant melanoma of the iris often originates from preexisting nevi.

A cellular subtype of malignant melanoma. It is a pigmented lesion composed of melanocytes occurring on sun-exposed skin, usually the face and neck. The melanocytes are commonly multinucleated with a "starburst" appearance. It is considered by many to be the in situ phase of lentigo maligna melanoma.

Found in large amounts in the plasma and urine of patients with malignant melanoma. It is therefore used in the diagnosis of melanoma and for the detection of postoperative metastases. Cysteinyldopa is believed to be formed by the rapid enzymatic hydrolysis of 5-S-glutathionedopa found in melanin-producing cells.

Clinically atypical nevi (usually exceeding 5 mm in diameter and having variable pigmentation and ill defined borders) with an increased risk for development of non-familial cutaneous malignant melanoma. Biopsies show melanocytic dysplasia. Nevi are clinically and histologically identical to the precursor lesions for melanoma in the B-K mole syndrome. (Stedman, 25th ed)
