Beyond the operation: demonstrating an integrated cancer-care pathway.

Both studies from the Department of Orthopaedic Oncology and Skin & Soft Tissue Tumours address a shared question: how can a specialist national centre maintain complex cancer surgery, staging, reconstruction and multidisciplinary decision-making amid prolonged disruption?

Team representationThe work was represented in Madrid by National Cancer Institute of Ukraine colleagues. Vasyl Ostafiichuk is a co-author of both studies but did not attend ESMO Congress 2026 in person. Scientific presentation and international engagement are team achievements.

Study 01 / Melanoma

Real-world surgical management of cutaneous melanoma in a national cancer center during wartime: a 2025 single-center registry analysis

Retrospective single-centre analysis of the 2025 operative registry.

329melanoma-related surgical cases

155WLE + sentinel lymph node biopsy

29reconstructions among 249 excisions

What the data show

Specialist surgical care during wartime continued to include wide local excision, sentinel node biopsy, therapeutic lymph node dissection and reconstructive surgery. Within 249 predefined excisions, 220 (89.1%) underwent primary closure and 29 (11.6%) reconstruction.

155 WLE + SLNB procedures and 39 therapeutic lymph node dissections in the source-verified registry.
Counts are operation-level, not an independently verified number of unique patients.
The clinical implication is preservation of a coordinated surgical oncology pathway and the importance of specialist centres.

Study 02 / Integrated oncology

Beyond tumor resection: integrated multidisciplinary surgical oncology care for skin and soft tissue malignancies in a national cancer center during wartime

Three distinct operation-level registries: melanoma, non-melanoma skin cancer and soft-tissue sarcoma.

750summed operation-level records across three registries

329non-melanoma skin cancer records

92soft-tissue sarcoma records

What the data show

The care pathway spans pathology, nodal staging, Mohs margin control, sarcoma surgery, reconstructive options and multidisciplinary decisions. The analysis describes service delivery rather than demonstrating the causal effect of wartime events.

Mohs: 111/149 facial lesions versus 9/180 other sites; reconstruction: 117/149 versus 16/180.
Sarcoma R0 resection margins: 72/83 evaluable cases (86.7%); nine Rx records excluded from this denominator.
13 documented wartime delays in the sarcoma registry, without a comparable prewar control group.
