Objective:

To determine the incidence and timing of hypopituitarism and other endocrinopathies in patients receiving ipilimumab and nivolumab for metastatic melanoma.

Key Findings:
  • Endocrinopathy was detected in 44.1% of patients, with 18.7% having hypopituitarism and 25.4% with primary hypothyroidism.
  • The median time to onset for hypopituitarism was 72.5 days and for hypothyroidism was 58 days.
  • Endocrinopathy development correlated with improved clinical outcomes.
  • Prompt endocrine replacement therapy was initiated for all affected patients.
Interpretation:

Routine monitoring for hypopituitarism and thyroid function is crucial in patients undergoing combination immunotherapy, given the high incidence of endocrinopathy.

Limitations:
  • The study was retrospective and limited to a single physician's patient cohort.
  • Potential biases in patient selection and data reporting may exist.
Conclusion:

Routine endocrine monitoring is strongly recommended for patients receiving ipilimumab and nivolumab due to the high rates of hypopituitarism and other endocrinopathies.
