Summary

Fine needle punctures can increase tumour cell migration, potentially causing metastases at the puncture site, particularly in advanced cancer stages. However, this risk is low and does not impact prognosis.

Area of Science:

  • Oncology
  • Pathology

Context:

  • Tumour cells circulate in the blood of cancer patients.
  • Metastasis formation is influenced by tumour cell numbers and patient immune status.

Purpose:

  • To investigate the impact of fine needle puncture on tumour cell migration and metastasis.
  • To assess the incidence and clinical significance of puncture-induced metastases.

Summary:

  • Fine needle puncture can lead to tumour cell migration into the bloodstream, potentially causing localized metastases.
  • Reported cases primarily involve advanced tumour stages, with no significant effect on disease course or prognosis.
  • The incidence of metastases in the puncture channel after fine needle biopsy is low (0.003–0.005%).

Impact:

  • Highlights the critical consideration of indications for fine needle puncture in malignant conditions.
  • Emphasizes the need for careful evaluation when the procedure may yield therapeutically relevant information despite low metastasis risk.
