Clinical Characteristics, Surgical Risks, and Long-Term Prognosis of Good's Syndrome

Area of Science:

• Thoracic Surgery
• Immunology
• Oncology

Background:

• Good's syndrome (GS) involves thymoma and hypogammaglobulinemia, leading to recurrent infections and poor prognosis.
• Minimally invasive techniques like VATS and RATS may improve thymoma surgery outcomes.

Purpose of the Study:

• To evaluate surgical outcomes and long-term prognosis of Good's syndrome patients undergoing thymectomy.
• To assess the safety and efficacy of minimally invasive approaches (VATS, RATS) in Good's syndrome thymectomy.

Main Methods:

• Retrospective review of 104 thymectomy cases (2007-2024) at Hokkaido University Hospital.
• Comparison of clinical background, surgical procedures, and outcomes between Good's syndrome and non-Good's syndrome patients.
• Survival analysis using Kaplan-Meier curves and log-rank tests.

Main Results:

• Seven of 104 cases had Good's syndrome, all with type AB thymoma.
• Perioperative outcomes were similar between Good's syndrome and non-Good's syndrome groups.
• Good's syndrome patients experienced persistent immunodeficiency, severe late infections (5 cases, 2 deaths), extrathymic malignancies (2 cases), and pure red cell aplasia (3 cases).
• Overall survival was significantly worse in Good's syndrome patients (p=0.002).

Conclusions:

• Thymectomy, including VATS and RATS, is safe for Good's syndrome.
• Long-term prognosis for Good's syndrome remains poor due to persistent immunodeficiency, infections, and secondary malignancies.
• Vigilant postoperative management is crucial for Good's syndrome patients.
