Pituitary prolactinoma, as a benign tumor originating from the pituitary gland, requires a comprehensive consideration of the patient's specific circumstances when choosing a treatment modality. First and foremost, the majority of patients with pituitary prolactinoma can achieve therapeutic goals through medical therapy, which effectively lowers prolactin levels and shrinks the tumor. Therefore, in most cases, surgery is not the first‑line option. 

However, surgery for pituitary prolactinoma may be necessary in certain specific situations. For example, for patients who are eager to conceive, unwilling to take long‑term medication, or unable to afford the cost of prolonged drug therapy, surgery may be a viable alternative. In addition, surgery may also be considered for patients who are resistant to oral medications, or for those with a pituitary macroadenoma (tumor >1 cm) accompanied by other pituitary hormone secretion abnormalities.

Is surgery recommended for pituitary prolactinoma?

I. Benefits and Risks of Surgery

1. Benefits:

- Rapid symptom relief: For patients in urgent need of alleviating symptoms such as visual deterioration and headache, surgery can quickly remove the tumor, relieve compression on surrounding tissues, and thereby ease symptoms.

- Improved fertility: For patients eager to conceive, surgery can rapidly lower prolactin levels and restore fertility.

- Elimination of the cause: Surgery can completely remove the tumor, avoiding the risk of continued growth and malignant transformation.

2. Risks:

- Surgical risks: Although the risks of surgery for pituitary prolactinoma have gradually decreased with advancing surgical techniques, inherent risks remain, such as intraoperative bleeding, infection, and edema.

- Pituitary dysfunction: Surgery may damage the pituitary gland itself, leading to pituitary dysfunction, such as growth hormone deficiency, abnormal prolactin secretion, and adrenocorticotropic hormone (ACTH) insufficiency.

- Neurological dysfunction: Surgery may injure surrounding nerves and the optic nerve, resulting in decreased vision, visual field defects, oculomotor disturbances, headache, and other symptoms.

- Antidiuretic hormone deficiency: Surgery may cause insufficient antidiuretic hormone (ADH), leading to abnormal urine excretion and reduced blood volume.

II. How to Choose the Appropriate Surgical Approach

The selection of the surgical approach for pituitary prolactinoma should be based on a comprehensive evaluation of the patient's specific circumstances:

- Tumor size: For smaller microadenomas, minimally invasive surgery, such as transsphenoidal microsurgery, can be performed. This approach is less traumatic and offers faster recovery. For larger macroadenomas, craniotomy may be required.

- Tumor location: The location of the tumor is also an important consideration. If the tumor is located in the posterior pituitary or close to critical structures such as the hypothalamus, the surgical approach must be chosen more cautiously to avoid damaging these important structures.

- Patient's general condition: The patient's overall health status is another critical factor. For older patients or those in poor physical condition, surgical risks need to be more carefully assessed, and the most appropriate approach should be selected.

III. Postoperative Sequelae

Possible sequelae after surgery for pituitary prolactinoma include the following:

1. Pituitary dysfunction: As mentioned above, surgery may damage the pituitary gland itself, resulting in pituitary dysfunction.

2. Neurological dysfunction: Surgery may injure surrounding nerves and the optic nerve, leading to decreased vision, visual field defects, oculomotor disturbances, headache, and other symptoms.

3. Antidiuretic hormone deficiency: Surgery may lead to insufficient ADH, causing abnormal urine excretion and reduced blood volume.

4. Intracranial infection: Surgery may cause intracranial infection, especially if the surgical site is not completely cleared or if bacterial infection occurs postoperatively.

5. Vascular injury: Surgery may damage the blood vessels supplying the pituitary, leading to interruption of blood supply, which can in turn cause serious conditions such as cerebral infarction, cerebral edema, and intracranial hemorrhage.

It is important to note that the incidence and severity of postoperative sequelae vary from person to person. After surgery, patients should closely monitor their physical condition, undergo regular follow‑up examinations, communicate promptly with their physicians, and adjust treatment plans to achieve optimal recovery.

Is surgery recommended for pituitary prolactinoma?

In summary, whether surgery is appropriate for pituitary prolactinoma and how to choose the surgical approach should be based on the patient's individual circumstances, tumor characteristics, and the multidisciplinary team's recommendations. Patients should work closely with endocrinologists and neurosurgeons to jointly develop a personalized treatment plan. When considering surgery, not only the potential benefits but also the possible risks and sequelae should be fully evaluated, and adequate preparation should be made.

Note: INC International Neurosurgeon Circle's International Neurosurgical Advisory Group (WANG) includes many internationally renowned professors with superb surgical skills and extensive successful case experience, such as Professor Sébastien Froelich (France), former Chairman of the Skull Base Surgery Committee of the World Federation of Neurosurgical Societies (WFNS). He specializes in endoscopic endonasal resection of skull base tumors, performing minimally invasive surgeries via neuroendoscopy for complex brain tumors including chordomas, craniopharyngiomas, and pituitary adenomas. His "chopsticks" technique in endoscopic surgery not only improves the tumor resection rate but also leads to better prognoses for tumor patients.

As a bridge connecting neurosurgical experts between China and other countries, INC International Neurosurgeon Circle has, in recent years, organized visits by international professors to China for academic exchanges, technological discussions, and high‑difficulty surgeries; it has also cooperated with multiple domestic hospitals to promote the common development of neurosurgery both domestically and internationally, providing more new treatment options for neurosurgical patients worldwide.
