Assessment of the impact of surgical treatment of primary malignant bone tumors on the quality of life of patients in peacetime and in the realities of wartime in Ukraine
Bibliographic record
Abstract
Background. The experience of researchers and clinicians in many clinics around the world shows that primary malignant bone tumors are one of the least studied groups of neoplasms, the diagnosis and treatment of which is a difficult task. The purpose was to assess the impact of surgical treatment of primary malignant bone tumors on the quality of life of patients in peacetime and in the realities of wartime in Ukraine. Materials and methods. Surgical treatment of 76 subjects with primary malignant tumors of the lower extremities (osteosarcoma and chondrosarcoma) was carried out: 32 patients were treated from 2019 to 2021, and 44 patients from 2022 to 2024. Patient’s quality of life index before and 3 weeks after surgical treatment was measured by the simplified version of the QLQ-C30 questionnaire, neurological component was evaluated according to our integrated version of the Hospital Anxiety and Depression Scale (HADS) for hospitalized cancer patients and the Montreal MoCA scale. Results. In the study group, the value of the quality of life index after treatment was 27.0 % higher than the value before treatment. In contrast, in the reference group, which shows data before the start of martial law, the value of the quality of life index increased after treatment by 114.5 %. In the reference group after treatment, the percentage of subjects with occasional anxiety decreased from 69 to 53 %, and with constant anxiety — by 3 times, that is, from 19 to 6 %; in the study group, the indices significantly did not change. The overall number of persons with anxiety remained unchanged at 84 %, while in the reference group, this index decreased from 88 to 59 %. Conclusions. Significantly higher results in improving the quality of life were demonstrated by the reference group — the value of the quality of life index of patients increased by 114.5 % after treatment. Among the neurological symptoms in the study group, anxiety prevails, the frequency of which did not decrease even after the treatment and remained unchanged at the level of 84 %, which also confirms the influence of chronic stress during the war.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
