ABSTRACT: Spatial tumour heterogeneity, which denotes the changes in cellular and molecular attributes across distinct locations within a tumour, significantly influences cancer diagnosis and treatment resistance. The heterogeneity of tumour cells inside a singular mass facilitates tumour development, metastasis, and the ineffectiveness of standard therapy. Comprehending the geographical distribution of tumour cells is crucial for formulating more efficient treatment regimens. Diverse methodologies are employed to investigate spatial heterogeneity, encompassing modern imaging techniques such as MRI, PET, and multiplexed imaging, alongside omics approaches including genomes, transcriptomics, and proteomics. These instruments offer insights into the tumour microenvironment and facilitate the identification of resistant subpopulations. The amalgamation of imaging and genomic data via radiogenomics has emerged as a viable methodology, providing an extensive perspective on the spatial and molecular intricacies of tumours. Principal findings reveal that spatial heterogeneity fosters medication resistance by establishing microenvironments characterised by varying oxygen levels, immunological infiltration, and genetic alterations, hence complicating the efficacy of monotherapy strategies. Hypoxic environments and immunological evasion significantly contribute to treatment resistance. Addressing geographical heterogeneity has the potential to enhance cancer treatments. By analysing the molecular and geographical characteristics of tumours, physicians can customise therapies more efficiently, minimising resistance and improving therapeutic results. This methodology signifies a vital advancement in precision medicine, providing more individualised and efficacious cancer therapies in the future.

ABSTRACT: Summary: The article presents the results of evaluating the diagnostic efficiency of ultrasound (US) in determining the extent of pathological processes in lymphoma patients. The study included 48 patients with Hodgkin’s and non-Hodgkin’s lymphoma who were hospitalized at the National Scientific Oncology Center from 2021 to 2024. All participants underwent comprehensive ultrasound of the abdominal parenchymal organs and lymph nodes using B-mode and Doppler imaging. The obtained data indicate high sensitivity and specificity of US in detecting liver, spleen, and abdominal lymph node involvement. Characteristic echographic signs of lymphatic conglomerates and associated complications such as ascites and exudative pleuritis were noted. Given the availability and safety of the method, US can be considered a key tool for primary diagnosis and lymphoma monitoring in clinical practice.
The purpose of the study: To evaluate the diagnostic efficiency of ultrasound (US) in assessing the extent of the disease in lymphoma.
Methods: A retrospective analysis of 48 medical records of patients with confirmed diagnoses of Hodgkin’s lymphoma (HL) and non-Hodgkin’s malignant lymphoma (NHL) who were treated at the National Scientific Oncology Center between 2021 and 2024. All patients underwent comprehensive abdominal ultrasound, pleural ultrasound, and lymph node imaging with Doppler.
Results: Pathological changes in lymph nodes, spleen, liver, and pleura were detected in all patients. In 60% of cases, the lymph node conglomerates appeared echonegative, while 5% showed signs of aggressive progression (undefined capsules, liquefaction). Typical echographic signs of diffuse and focal organ changes were observed.
