miRNA to Guide Appropriate Intervention of Small Testis Masses (miRSTM)

2026年9月25日 更新者：University Health Network, Toronto

miRNA as a Liquid Biomarker to Guide Early Detection and Appropriate Intervention of Incidentally Detected Small Testicular Masses

This study aims to determine, for the first time, if miRNA-371a-3p can be used as an accurate biomarker to identify which small (≤ 2cm) testicular masses are malignant and aid in clinical decision-making to offer surgery or surveillance. We propose a retrospective exploration of banked serum, plasma and semen specimens of men with small testis masses and a prospective biomarker-based intervention trial to validate miR-371a-3p performance.

Study Intervention:

Blinded measurement of miRNA expression in blood and/or seminal plasma after the decision of treatment choice has been made. Participants will undergo usual clinical care and follow a program of surveillance or surgical removal based on a clinician and patient shared decision.

Primary Objective: To determine if surveillance can be offered as a biomarker-based strategy to patients with solitary small testicular masses (STMs) ≤ 2cm.

Secondary Objectives: 1)To assess the performance characteristics of serum, plasma, and seminal plasma miRNA in a prospectively collected cohort of patients presenting with solitary masses small testicular masses ≤ 2cm.

2)To determine the association between miRNA and the presence of testicular cancer in radical or partial orchiectomy surgical specimens.

3)To evaluate surveillance as a treatment strategy in patients with STMs, negative serum tumour markers and negative miRNA secretion, assessing treatment-free survival (TFS) and metastasis free survival (MFS).

4)Refining analytic methods in miRNA assessment by inter-lab comparison, determining best practices and optimal cut-offs to develop a CLIA-approved assay.

5)To establish an optimal threshold for considering an incidentally found testis mass as a small testicular mass.

Endpoints of the study:

  • Treatment free survival (TFS) for those on surveillance
  • Metastasis free survival (MFS)
  • Expression of miRNA in serum/plasma and/or seminal plasma in patients with STMs
  • Correlation between secretion of miRNA in STMs and GCTs or GCNIS identified in subsequent pathologic examination of surgical specimens or biopsy
  • Percentage of patients that can avoid surgery or intervention
  • Establishing an optimal surveillance protocol for patients with STMs
  • Quality of Life and anxiety in patients undergoing surveillance compared with patients undergoing active treatment
  • Expression of miRNA in patients with infertility and testicular tumours in serum/plasma and/or seminal plasma

Patients with small testicular masses

描述

Inclusion Criteria:

  • • Small testicular mass/masses ≤ 2cm

    • Patients with serum tumour marker elevation are eligible only if they are considered for surgical treatment, or if markers are felt to be falsely elevated by the physician team
    • If the patient previously had chemotherapy, the mass must first have appeared only after the treatment completed
    • The patient is at least 18 years of age
    • Ability to understand and comply with the requirements of the study
    • Ability to understand and willingness to sign a written informed consent

Exclusion Criteria:

  • • Patients with testicular tumours > 2 cm

    • Metastatic disease
    • Patients in reduced general condition, with uncontrolled intercurrent illnesses, or with life-threatening disease
    • Patients with psychiatric illnesses that would limit compliance with study requirements
    • Clinical decision is made by the multidisciplinary team that patient is not suitable for surveillance
