Hypothesis

To evaluate the antihormonal and antitumour efficacy of long-term primary treatment with somatostatin analogues in patients with GH-secreting pituitary adenoma responsive to SSTa.

Conclusion

Long-term treatment with somatostatin analogues is effective in controlling hormone levels and reducing tumor size in acromegalic patients.

Supporting Evidence

  • After 1 year, mean GH and IGF-1 levels significantly decreased.
  • 70% of patients achieved GH levels below 2 µg/l after treatment.
  • 43% mean reduction in tumor size was observed.

Takeaway

This study shows that a medicine called somatostatin can help people with a certain type of tumor by lowering their hormone levels and shrinking the tumor over many years.

Methodology

An open, prospective, single-centre clinical study monitoring patients treated with SSTa for a mean duration of 8 years.

Limitations

The study was conducted at a single center, which may limit the generalizability of the results.

Participant Demographics

The cohort included 17 men and 19 women with a mean age of 53 ± 2.5 years.
