Laparoscopic surgery for malignant adrenal tumors

Area of Science:

• Endocrine Surgery
• Surgical Oncology
• Adrenal Gland Neoplasms

Background:

• Improved imaging enhances early detection of adrenal tumors, both primary and metastatic.
• Laparoscopic adrenalectomy is standard for benign adrenal diseases but its role in malignant tumors is debated.
• The rarity of adrenal cancer limits prospective randomized trials on surgical approaches.

Purpose of the Study:

• To review the literature on the safety and efficacy of laparoscopic adrenalectomy for adrenal tumors.
• To define criteria for considering laparoscopic approaches in primary adrenal malignancies.

Main Methods:

• Literature review of studies on laparoscopic adrenalectomy for adrenal tumors.
• Analysis of safety and efficacy data, focusing on tumor characteristics and surgical outcomes.

Main Results:

• Laparoscopic adrenalectomy is demonstrated as safe and effective for solitary adrenal tumors.
• For primary adrenal malignancies, laparoscopy is feasible only if complete resection with an intact capsule is achievable.
• Early conversion to open surgery is necessary for tumors with local invasion, large size, or requiring organ resection.

Conclusions:

• Laparoscopic adrenalectomy can be considered for select primary adrenal malignancies when oncologic principles are maintained.
• Careful patient selection and surgical planning are paramount to ensure successful outcomes and avoid complications.
• Open adrenalectomy remains the standard for locally advanced or complex adrenal cancers.
