BULGARIAN JOINT CANCER NETWORK (BJCN)

National Cancer Network in the Republic of Bulgaria. The abbreviation SONM is an old Bulgarian word meaning both a human multitude and a gathering of gods (pantheon).

The legal format of BJCN is a non-governmental non-profit association with activities for the public benefit. In social terms, it is an open cluster organization, functioning as an ecosystem of medical and non-medical societies with a wide range of multidisciplinary interdependencies in the field of oncology.

The main goals of BJCN are synergy in the expert functions of individual medical societies in Bulgaria dealing with fundamental and/or clinical oncology; optimizing cooperation between branch societies and the “triangle” of social knowledge (universities, industry, government); initiating and developing innovations for oncological care in Bulgaria, including screening and prevention, diagnosis and treatment, psychosocial support and quality of life and digitalization.

BJCN works through network synergy, differentiated into cluster sectors and respective coordination groups, adhering to three principles: (i) multiplication of cluster interactions, (ii) exchange of mutual benefits and (iii) positive external cluster effect.

DIGITAL SOLUTIONS AND INNOVATIONS

Coordinator: M.Pharm. Ivaylo Petrov

Teleoncology
BJCN partners with the Bulgarian company Shemha Health in the development and testing of an innovative teleoncology platform PrOPA (Precision Oncology Patient Advice). The platform functions as a digital tumor board for personalized oncology care, uniting all diagnostic and therapeutic modalities within a single digital, integrated oncology center. ProPA is designed to optimize processes in oncology care by providing precise and evidence-based treatment recommendations, reducing the time for clinical decision-making and facilitating a multidisciplinary approach in the treatment of cancer.

BJCN is in collaboration with the International Agency for Research on Cancer (IARC) on the implementation of the CanScreen-ECIS project, the aim of which is to improve the quality, monitoring and evaluation of cancer screening programs in Europe. The project supports data collection, capacity building and the adoption of evidence-based policies for effective and equitable early cancer detection.

BJCN participates in Work Package 4 (Sustainability) of the EU Project eCAN to strengthen eHealth for cancer patients.

Network connectivity

Since February 4, 2024, BJCN is a full member and representative of Bulgaria in ALL.Can International – an international network of leading representatives of patient organizations, politicians, healthcare professionals, researchers and industry experts from all over the world. The main mission of ALL.Can International is to identify unmet needs in oncology care and, through research and interaction, to demonstrate best practices. The organization develops systemic solutions and policies to improve oncology care by focusing on what is of greatest importance to patients.

Since June 18, 2024, BJCN has been officially included as the representative of Bulgaria in the ECHoS initiative (Establishing Cancer Mission Hubs: Networks and Synergies). ECHoS is a European project uniting over 60 leading organizations in the field of healthcare, research and innovation, academia and the non-governmental sector from 30 countries. Funded under the Horizon Europe programme, the project aims to support the implementation of the Mission to Fight Cancer activities in all Member States and Associated Countries, with a focus on the establishment and development of National Hubs. As part of ECHoS, the ONS takes responsibility for building a network for cooperation and dialogue aimed at the introduction and implementation of policies related to cancer prevention and treatment. The initiative aims to create sustainable synergies and interactions at national and international level, supporting innovative solutions and good practices in cancer care.

Since 27 November 2024, the ONS has been an associate member of the European Cancer Organisation (ECO) – a European federation uniting organisations involved in the field of oncology at European level. ECO focuses on facilitating cooperation to develop and coordinate policies aimed at improving the quality of care for patients with cancer. This is achieved through interprofessional and multidisciplinary interaction between medical and non-medical organisations, as well as experts from different public sectors.

CLINICAL GUIDELINES, PERIODICALS, CONFERENCES

BJCN-MORE Expert Boards

Since 2010, National Expert Multidisciplinary Boards have been formed, which annually create national guidelines for clinical behavior in a specific localization of cancer. Members of the expert boards (EB) are leading specialists from all areas of Bulgarian clinical oncology and are determined depending on the localization of the oncological disease. The nominal composition of the EB is published in the relevant annual editions of the clinical guidelines and textbooks.

BJCN-MORE Clinical Guidelines

Guidelines based on evidence, created annually by national multidisciplinary expert boards since 2010. They include recommendations for clinical behavior in solid tumors of different localization in adults and children, for predictive biomarkers and for psychosocial support in oncology. The Oxford CEBM method was used to analyze evidence and formulate recommendations, and since 2020, the GRADE approach.

In 2022, the innovation MORE e-Guidelines was introduced – an original digital platform for creating and updating evidence-based oncology clinical guidelines.
