Craniopharyngioma in adults

Area of Science:

• Neurosurgery
• Endocrinology
• Oncology

Background:

• Craniopharyngioma diagnosis is often delayed by years due to nonspecific symptoms like headaches and endocrine dysfunction.
• This retrospective study analyzes outcomes for adult patients treated surgically for craniopharyngioma.

Purpose of the Study:

• To evaluate the surgical outcomes, including survival rates, visual function, and endocrine changes, in adult patients with craniopharyngioma.
• To identify factors influencing prognosis and emphasize the importance of early diagnosis.

Main Methods:

• Retrospective review of 29 adult patients who underwent surgery for craniopharyngioma between 1970 and 1981.
• Analysis of surgical approaches (total removal, partial removal, palliative surgery) with or without radiotherapy.
• Assessment of survival rates, visual acuity, visual fields, and endocrine status (hypopituitarism, body weight changes).

Main Results:

• Overall surgical mortality was 3 patients, with 1 accidental death post-surgery.
• Five-year survival varied significantly by surgical approach: 100% for total removal, 91% for partial removal, and 0% for palliative surgery.
• Radiotherapy influenced survival, particularly in conjunction with palliative surgery (100% survival).
• Visual acuity improved in 9/23 patients, while visual fields improved in 8/21.
• Surgery led to increased hypopituitarism, and 8/15 patients experienced a significant increase in body weight post-surgery.

Conclusions:

• Surgical management of craniopharyngioma is associated with significant morbidity and mortality.
• Total or partial tumor removal offers better survival rates compared to palliative surgery.
• Earlier diagnosis of craniopharyngioma is likely to improve patient prognosis and long-term outcomes.
