The dynamic development of molecular biology led to exploration of a range of phenomena underlying the process of neoplastic transformation and contributing to fast development of therapies based on monoclonal antibodies and small-cell kinase inhibitors. However, multiple analyses have shown that these drugs are effective only in selected patients, and therefore it is necessary to test multiple molecular markers at the diagnostic stage to allow identification of those patients who can achieve the greatest benefits with the applied treatment. The number of tests imposed by provisions of drug programmes leads to multiple questions concerning selection of the testing method, quality standards to be met by diagnostic laboratories, and the major ones – concerning the possibility to settle the funding of individual tests. The present paper summarises the major aspects of molecular cancer diagnosis recommended and available in clinical practice in Poland.
Genetic testing at medical diagnostic laboratories
Genetic Diagnostics Departments/Labs at referential oncology centres should employ a staff of experienced lab diagnosticians and specialists in laboratory medical genetics. The basic role of these units is to perform diagnostic genetic tests designed to identify germinal mutations (constitutive mutations) and somatic mutations (genetic testing in acquired cancers). Genetic cancer diagnostics allows, above all, differential diagnosis, qualifying patients for targeted therapies, and also it enables monitoring of treatment course [1]. Within the diagnostic process, molecular analyses are also applied for assessing the development risk for the given cancer and as a basis for providing genetic counselling and prophylaxis for high-risk family members [2].
Genetic tests performed within a single medical centre allow introduction of integrated, interdisciplinary oncological diagnostics. The organisational structure and close multi-specialisation cooperation of lab diagnosticians, clinical physicians, pathomorphologists and geneticists enables specialist and comprehensive diagnostics in a single centre, without a need to send material to external cooperating units. Thus, the testing time is reduced to minimum, there is a possibility of consultation of the case with specialists in various medical specialties, and at the same time the risks involved in sample transport (e.g. sample loss or damage) are eliminated by application of consistent procedures for sample protection. Importantly, the material remains within the centre and if needed, it is available for re-analysis applying another technology. Further, if the result cannot be obtained, due to degradation of the genetic material or for other reasons, quick reaction is possible by re-harvesting a sample or using material harvested at another procedure or biopsy, if the archival material is representative [3].
Peripheral blood, drawn for assessment of germinal mutations or assessment of somatic mutations (referred to as liquid biopsy) on the level of extracellular nucleic acids – ctDNA (circulating tumour DNA) can be used material for genetic testing, if drawn upon prior written consent by the patient to diagnostic genetic testing. It should be referred directly to the genetics unit. Genetic testing of histopathology material (archival material fixed as paraffin blocks) performed upon acquisition of the patient’s consent to diagnostic genetic testing, must be assessed by pathomorphologists to evaluate applicability of the material for molecular testing and to select the right sample (see: section about the role of pathomorphology in molecular diagnostics) [4].
A report of the completed genetic diagnostic test should include the test result, precise interpretation understandable for a clinical oncologist, clinical geneticist, pathomorphologist and the patient, as well as the scope and description of methods applied [5].
Genetic testing requires equipment with full technical documentation concerning repairs, validations and confirmation of annual inspections (Regulation of the Minister of Health of 21 March 2006 (Journal of Laws of 2006, no. 59, item 422, as amended). A genetic lab should hold experience of at least five years in working with peripheral blood material, tissue material, cytology material, extracellular nucleic acids; and it should have developed and implemented procedures, lab instructions, as well as internal quality control systems. It must be managed by a specialist in medical genetic diagnostics. The experience in testing germinal and somatic mutations should be documented by certificates of international quality control. The employed staff should be experienced and skilled in interpretation of the identified genetic variants based on medical databases, medical literature and bioinformatics analytical software in silico. All requirements set for diagnostic labs were described in the Regulation of the Minister of Health concerning quality standards for diagnostic labs and microbiology labs (Journal of Laws of 2019, item 1923).
A lab providing genetic testing for oncology diagnostics should ensure that the following tests are available at all times with no exceptions:
- Sanger direct sequencing – germinal and somatic mutations – testing of selected fragments of the DNA in genes where pathogenic variants can be located; targeted testing of selected genetic variants; verification of variants obtained by large-scale NGS methods. In assessment of histopathology material it is recommended that the tested preparations should contain no less than of 20% cancer tissue. Performance of macro- or micro-dissections is recommended to obtain the highest proportion of cancer tissue.
- Next-generation sequencing (NGS) – technology dedicated to comprehensive molecular diagnostics allowing parallel detection of multiple molecular markers and many classes of genetic mutations (point mutations, small deletions/insertions, big deletions, amplification, gene fusions), including genome signatures such as MSI (microsatellite instability), TMB (tumour mutational burden), HRD (homologous recombination deficiency). In testing germinal, as well as somatic mutations, panel (or targeted) next-generation sequencing can be applied, involving assessment of a selected pool of genes. In assessment of histopathology material it is recommended that the tested preparations should contain no less than of 20% cancer tissue (no less than 30% in the case of HRD testing). Performance of macro- or micro-dissections is recommended to obtain the highest share of cancer tissue.
- qPCR (modification of the PCR method referred to as quantitative real time PCR) –method dedicated to identification of only known genetic variants; quick method of high sensitivity of 1% to 0.2%. It allows identification of genetic mutations in material of scarce cancer tissue (5–15%) and ctDNA. Performance of macro- or micro-dissections is recommended to obtain the highest proportion of cancer tissue.
- FISH (fluorescent in situ hybridisation); CISH (chromogenic in situ hybridisation) – routine diagnosis of gene rearrangements, including gene fusions and gene amplifications.
- MLPA (multiplex ligation-dependent probe amplification) – method dedicated to assessment of large genetic rearrangements including deletions and duplications. Dedicated mainly to assessment of germinal mutations. Frequently applied to verify mutations identified by large-scale techniques, such as NGS.
- Other techniques: ddPCR (droplet digital PCR) – one of the most sensitive techniques in molecular biology applied in testing selected genetic variants, especially on the ctDNA level. Pyrosequencing – method allowing assessment of methylation of selected DNA sequences. aCGH (array comparative genomic hybridisation) – cytogenetic method which involves detection of loss or amplification of chromosome regions or gene(s) characterised by very high resolution – for SNP assessment (single-nucleotide polymorphism) and evaluation of gene expression profile.
Role of pathomorphology in molecular diagnostics
Tissue and cytology material is used for molecular biology testing mainly in order to determine the right pathomorphological diagnosis of the cancer according to the currently binding classifications of the World Health Organisation (WHO) and to identify patients who may benefit the most from personalised therapies. Such tests require involvement of a diagnostic team including physicians specialising in pathomorphology, lab diagnosticians specialising in medical genetic diagnosis, biologists, biotechnologists and lab technicians. Labs/departments of pathomorphology (units specialising in pathomorphology diagnostics) within the highly-specialist healthcare institutions should have guaranteed access to the listed types of tests performed either in their own specialist labs or within a close cooperation with diagnostic labs specialising in analyses associated with medical genetic lab diagnostics [6, 7].
The quality of the genetic material (least possible degree of DNA/RNA degradation) is determined by observance of the right procedures at particular stages of processing of the biological material. The most important factors allowing maintenance of high quality of the tissue material include:
- delivery of the harvested material to the pathomorphology lab as fast as possible;
- fixing in 10% buffered formalin (4% solution of formaldehyde, pH 7.2–7.4, ambient temperature at most),
- adaptation of the fixing time to the size of the material (small histology material: up to 24/48 h, big histology material: up to 48/72 h).
Further processing of the tissue material must be standardised according to norms/requirements approved by the Ministry of Health and procedures recommended by the Polish Pathology Society and their latest updates. Each sample (paraffin block and corresponding microscopic preparation stained with hemotoxylin and eosin) – originating from the selected material for pathomorphology testing and designed for molecular testing – must be assessed by a physician specialising in pathomorphology to confirm the diagnosis, determine presence of cancer tissue and describe the proportion of cancer cells in the preparation. A physician specialising in pathomorphology chooses the best sample (procedure of qualifying material for molecular testing) in the context of molecular testing, considering also the sequence of planned diagnostic stages. In the case of materials sent from other centres, it is reasonable to provide all paraffin blocks to ensure the right qualification for the molecular testing considering the necessity to choose the material of the highest quality. If there is no adequate material for molecular testing (e.g. the material is too scarce, the proportion of cancer cells is too low or the material is technically damaged), a physician specialising in pathomorphology may recommend re-harvesting of material from the patient. The technical requirements concerning harvesting material from a paraffin block for isolation of nucleic acids (cutting blocks, their storage and delivery for molecular testing) are described in detail in the quoted guidelines.
Cytology smears (material for exfoliative and aspiration cytology, in the form of smear on basic glassware, fixed with alcohol 95–96%) and cyto-blocks (material for exfoliative and aspiration cytology fixed and submerged in a paraffin block) may also serve as valuable material for molecular testing. The binding rules for qualification of samples by a physician specialising in pathomorphology are the same as described above with respect to tissue material. In the case of smears, digital archiving of materials is recommended before their delivery for molecular analysis, because the biological material is entirely and irreversibly used.
The result of molecular assessment, necessary either for pathomorphological diagnosis, or for personalised treatment, should be included in the final/comprehensive pathomorphology report (including a summary or so-called synoptic report) in the case if the medical diagnostic lab is a part of the pathomorphology diagnostic unit or it may be attached to the report. Regardless of the organisational relations, provision of material for molecular testing requires cooperation and efficient communication to ensure fluent and optimal process of diagnostics. In order to ensure the right pathomorphology diagnostics, introduction of a separate model of funding of these tests is expected, based on the JGPato model, currently in development.
Funding of genetic diagnostic tests by the public payer
The right organisation of genetic diagnostics in oncology applying modern methods of molecular biology translates to improvement of the achieved outcomes of patient treatment, however, it requires additional funding [8]. Costs of genetic testing for oncologic patients vary depending on the applied testing technique and the number/type of procedures necessary to obtain an unequivocal, clinically useful result. There are several way of financial settlement of genetic tests within cancer diagnostics.
Considering the variable costs of genetic tests in oncology patients, the public payer introduced in 2017 a possibility to fund them within a hospitalisation agreement depending on ICD10 diagnosis, used diagnostic technology, number and type of the markets and moment of harvesting material for testing:
- archival material – provided from another centre or harvested at the given healthcare institution at a diagnostic procedure during earlier hospitalisation (fixed tissue and cytology material/paraffin blocks and preparations), or
- freshly harvested material sampled during hospitalisation (peripheral blood or material harvested during a surgical procedure and fixed as paraffin blocks or cytology material).
According to the Ordinance of the President of the National Health Fund concerning determination of terms of conclusion and implementation of agreements in the hospitalisation category (as amended), the possibility to settle diagnostic genetic testing in cancers was assigned to 15 areas both in conservative and surgical procedures (according to Attachment 1c to calculation): paediatric surgery, chest surgery, oncologic surgery, pulmonary disease / pulmonary disease in children, endocrinology, gastroenterology, oncologic gynaecology, haematology, neonatology, neurosurgery, paediatric oncology and haematology, clinical oncology, obstetrics and gynaecology, urology. It is not possible to settle genetic testing within general surgery.
For settlement of genetic testing in cancers within hospitalisation contracts, there are dedicated settlement products in catalogue 1c (for calculation) which allow funding of diagnostic genetic testing of material harvested during hospitalisation or archival material:
- basic genetic testing in cancers (code 5.53.01.0005001) – refund of 649 points,
- complex genetic testing in cancers (code 5.53.01.0005002) – refund of 1,298 points,
- advanced genetic testing in cancers (code 5.53.01.0005003) – refund of 2,434 points.
Currently, this is the most favourable variant of settlement of genetic testing in cancers.
The basic condition of settlement of genetic testing in oncology within the hospitalisation agreement involves holding a contract with the National Health Fund concerning provision of healthcare services of the type “hospitalisation” in at least one area listed in catalogue 1c of the ordinance. Hospitalisation involving harvesting of material for genetic testing should be justified by medical considerations and correctly documented. Upon obtaining a result of a genetic test, the JGP group in catalogue 1a should be expanded by the correct settlement product as indicated by the genetics lab: simple, complex or advanced genetic testing in cancers.
Originally, reporting of genetic tests involved a necessity of hospitalisation of the patient, as harvesting of the material for diagnostic testing was an in-patient procedure. A change was introduced early in 2018 with introduction of a possibility to settle out-patient genetic diagnostic tests in cancers performed on archival material which could have been harvested by other providers. In this case, we apply product 5.52.01.0001511: genetic testing of archival material. The product’s value is 0, but it allows reporting and settlement of genetic tests: simple, complex and advanced ones, if the treatment plan has to be modified. The service concerning genetic testing of archival material (code 5.52.01.0001511) is meant for out-patient procedures, but it is settled within an in-patient agreement. It is also obligatory to report the original date of harvesting of the material for testing.

Further, reimbursement of costs of genetic testing in cancers can be based on other agreements concluded between service providers and the National Health Fund:
- Agreements concerning separately contracted services (SOK), which may fund tests on material harvested during an out-patient or in-patient diagnostic procedure as product (5.10.00.000041) – complex genetic diagnostics of cancers – 534 points.
- The least favourable financial settlement involves an agreement concerning out-patient specialist care with settlement product (5.03.00.000021) – RNA/DNA detection with molecular tests (PCR/PFGE) – 300 points.
- In the case of haemato-oncological drug programmes, it is admissible to settle genetic testing during qualification for drug programmes with so-called diagnostic lump amount.
- Additionally, since September 2022 some service providers may perform specific genetic tests within a programme of care for families with high risk of hereditary breast cancer or ovarian cancer, as well as colon cancer or endometrial cancer.
