Preoperative Pneumococcal and Influenza Vaccination to Prevent Postoperative Pulmonary Infection in Patients Undergoing Lung Resection for Pulmonary Nodules or Lung Cancer
Preoperative Respiratory Infectious Disease Vaccination (23-Valent Pneumococcal Polysaccharide Vaccine and Quadrivalent Split-Virion Influenza Vaccine) for the Prevention of Postoperative Pulmonary Infection in Patients With Pulmonary Nodules/Lung Cancer: A Multicenter, Prospective, Randomized, Open-Label, Blinded-Endpoint (PROBE) Clinical Trial
Forrás: ClinicalTrials.gov · Utoljára frissítve: 2026. okt. 21.
Rövid összefoglaló (regiszter, angolul)
Postoperative pneumonia (POP) affects 4%-24% of lung cancer surgery patients, increasing mortality, stay, costs and worsening prognosis, especially in older patients. Perioperative immunosuppression and synergistic influenza/pneumococcal infection support perioperative vaccination, which may also induce trained immunity; thoracic surgery data are lacking. This multicenter, prospective, randomized, open-label, blinded-endpoint (PROBE) trial will enroll ~1278 patients aged ≥50 undergoing anatomical lung resection for pulmonary nodules or lung cancer, randomized 1:1 to vaccination or no vaccination, with 180-day follow-up. Randomization uses a computer-generated, site-stratified block sequence, concealed via central IWRS or sealed envelopes. An unblinded team handles screening, randomization and vaccination data; surgeons and assessors are blinded. No site may exceed 50% of enrollment. Vaccination group receives 23-valent pneumococcal polysaccharide and quadrivalent influenza vaccines intramuscularly in separate arms 14-28 days preoperatively. Controls receive no vaccine/placebo, with surgery scheduled 14-28 days after randomization. Concomitant indicated treatments are permitted and recorded. Primary endpoint is POP per modified CDC/NHSN criteria: new/progressive imaging infiltrate (excluding atelectasis, edema, embolism, tumor), plus ≥1 clinical sign (fever >38 °C, WBC ≤4000 or ≥12,000/mm³, or altered mental status if ≥70 years) and ≥2 respiratory signs. Findings on days 3-5 are excluded unless persistent/worsening. Microbiology is confirmatory, not required.

Ki nem vehet részt
Szó szerint a(z) ClinicalTrials.gov forrásból, témák szerint csoportosítva. Hogy ki vehet részt, azt csak a vizsgálat csapata dönti el.
Korábbi kezelés
- Previous pneumococcal vaccination within 5 years, influenza vaccination within 1 year, or any other vaccination within 4 weeks
- Pulmonary infection, or active infection requiring systemic treatment (e.g., severe pneumonia, bacteremia, sepsis), within 1 month before surgery
- Use of antibiotics or antiviral drugs within 1 month before surgery
- Other surgery or invasive treatment within 1 month before surgery (diagnostic needle biopsy excluded)
- Prior neoadjuvant therapy (chemotherapy, radiotherapy, targeted therapy, immunotherapy, etc.), or planned adjuvant therapy within 30 days after surgery
Más betegség
- Known allergy to any vaccine component
- Active autoimmune or inflammatory disease (e.g., Guillain-Barre syndrome, systemic lupus erythematosus, psoriasis requiring systemic treatment, rheumatoid arthritis, inflammatory bowel disease, Hashimoto thyroiditis); type 1 diabetes, hypothyroidism controlled by replacement therapy alone, and skin conditions not requiring systemic treatment (e.g., vitiligo, psoriasis) are allowed
- HIV antibody positive; active tuberculosis; active hepatitis B (HBV-DNA above the lower limit of detection); or active hepatitis C (HCV antibody positive and HCV-RNA above the lower limit of detection)
- History of allogeneic organ transplantation (solid organ or allogeneic bone marrow)
- Emergency surgery, or risk of disease progression (e.g., short tumor doubling time) that does not allow waiting for the 14-day vaccine response window
Laborértékek
- Any serious illness, uncontrolled concurrent disease, psychiatric disorder, active or uncontrolled infection, other medical history or laboratory abnormality that, in the investigator's opinion, may interfere with participation or interpretation of results
Egyéb
- Pregnant or breastfeeding women
