What is Pituitary Tumor ?

A pituitary tumor is an unusual/ abnormal growth in the pituitary gland, a vital endocrine gland located at the base of the brain. It refers to a pea-sized gland that controls major body functions. Through hormones it produces, the pituitary gland regulates endocrine functions involving the thyroid, adrenal glands, and reproductive organs. The pituitary gland serves as the endocrine system's master gland because it functions as the central control system for all hormonal activities in the body.

Pituitary tumors develop when pituitary gland cells start to multiply beyond their normal growth limits. Most pituitary tumors are benign (non-cancerous) and are known as pituitary adenomas. Even though these tumors are not cancerous, they cause significant health problems as they neither spread to other areas of the human body nor develop into cancer. The tumor might produce excessive hormones by blocking hormone production and exerting pressure on other structures of the body, including the brain and the retina.

They tend to grow gradually and remain unnoticed for several years. These tumors might come to attention accidentally during imaging examinations performed to evaluate other disorders. Some cases arise in which patients present with complaints due to hormonal disturbances or compression of adjacent tissues.

Thanks to improved imaging, hormone testing, neurosurgery, and medicine, treating pituitary tumors has improved significantly. Most people with pituitary tumors can live a normal life without any problems if they get the right treatment.

What is Pituitary Gland ?

The pituitary gland exists in the sella turcica of the human skull, at the base of the brain. It forms part of the sphenoid bone. The hypothalamus links to the pituitary gland through the pituitary stalk. The hypothalamus is the major controller of the different body systems, including the pituitary gland's hormone secretion.

The pituitary gland has two main divisions: the anterior pituitary and the posterior pituitary.

Anterior Pituitary (Adenohypophysis)

The anterior pituitary forms different hormones that influence other glands in the body. The hormones produced by the body include the following substances:

• The body uses growth hormone (GH) to regulate growth and metabolic functions.
• Prolactin (PRL) - stimulates breast milk production
• ACTH (Adrenocorticotropic hormone) - It stimulates the adrenal glands to produce cortisol
• Thyroid -stimulating hormone (TSH) regulates the thyroid gland.
• Luteinizing hormone (LH) - regulates reproductive functions.
• Follicle-stimulating hormone (FSH) - controls fertility and reproductive development.

The body uses hormones to control essential functions, including metabolic processes, growth and development, stress responses, and reproductive activities.

Posterior Pituitary (Neurohypophysis)

The hypothalamus produces hormones, which the posterior pituitary stores and releases. The following chemicals are used by the body:

• Antidiuretic hormone (ADH) - controls water balance and kidney function
• Oxytocin - It is very important in childbirth and breastfeeding.

The pituitary gland regulates various hormones throughout the body, allowing tumors that affect it to affect multiple organ systems.

How many Types of Pituitary Tumors ?

Medical professionals classify pituitary tumors according to various factors, including tumor diameter and hormone secretion status.

1. Based on Size

   1. Microadenomas

      Microadenomas are tumors measuring less than 1 centimeter in diameter. The tumors exist as common medical conditions that typically remain asymptomatic in most patients.

   2. Macroadenomas

      Patients develop symptoms from macroadenomas that exceed 1 centimeter in size because these tumors apply pressure on nearby structures, including the optic nerves.

2. Based on Hormone Production

   Tumors from the non-functioning pituitary category fail to generate any hormonal substances. The tumor growth symptoms begin when the tumor reaches a size that applies pressure on surrounding tissues, which disrupts regular pituitary operations

   1. Functioning (Hormone-Secreting) Tumors

      Hormonally active tumors produce excessive hormone quantities, which lead to endocrine system medical issues.

      The main examples of this category include:

      1. Prolactin-secreting tumors (Prolactinomas)

         The most common pituitary tumor type stems from this category.

      2. Growth hormone-secreting tumors

         The tumors cause an excess growth of hormones.

      3. ACTH-producing tumors

         The tumors push the adrenal glands to produce more cortisol than needed.

      4. TSH-secreting tumors

         Rare tumors lead to excessive thyroid hormone production by stimulating the thyroid gland.

   2. Non-Functioning Tumors

What are the Causes & Risk Factors of Pituitary Tumor ?

In most cases, the exact cause of pituitary tumors remains unknown. The researchers believe that genetic mutations inside pituitary gland cells initiate their abnormal growth patterns.

Genetic Mutations

Tumor development occurs through a series of genetic mutations that affect cell growth control functions.

Hereditary Syndromes

Certain inherited disorders increase the likelihood of developing pituitary tumors. The following disorders are included in this group:

• Multiple endocrine neoplasia type 1 (MEN1)
• Carney complex
• Familial isolated pituitary adenoma (FIPA)

The conditions occur infrequently, yet they lead to tumor development in multiple endocrine glands.

Age

Pituitary tumors usually occur at any age, but are most commonly diagnosed in adults between 30 and 60 years of age.

Gender

Certain types of pituitary tumors, especially prolactinomas, are more commonly diagnosed in women.

What are the Signs & Symptoms of Pituitary Tumor ?

The signs and symptoms of pituitary tumors differ according to the tumor size, its growth speed, and its hormone production activity.

Symptoms Caused by Hormone Overproduction

Patients experience specific disorders due to their bodies producing excessive hormones.

Prolactinomas

High prolactin levels may cause:

• Irregular or absent menstrual cycles
• Infertility
• Breast milk production is unrelated to pregnancy.
• Decreased libido
• Erectile dysfunction in men

Growth Hormone Tumors

Excess growth hormone causes acromegaly in adults.

The symptoms involve:

• Enlarged hands and feet
• Thickened facial features
• Enlarged jaw
• Joint pain
• Increased sweating

Excess growth hormone in children leads to gigantism, causing them to grow beyond normal height.

ACTH-Producing Tumors

The tumors generate Cushing's disease, which causes these symptoms:

• Weight gain, which primarily affects the upper body
• Round facial appearance
• Purple stretch marks
• High blood pressure
• Diabetes
• Thin skin and easy bruising

TSH-Producing Tumors

The tumors cause hyperthyroidism because they produce too much thyroid hormone, which leads to symptoms like:

• Rapid heartbeat
• Weight loss
• Anxiety
• Excessive sweating

Symptoms Caused by Pressure on Surrounding Structures

Large tumors create pressure that affects adjacent body parts, thus producing these symptoms, which include:

• Persistent headaches
• Vision problems, especially loss of side vision
• Double vision
• Nausea and vomiting
• Fatigue
• Hormonal deficiencies

Bitemporal hemianopsia occurs when optic nerve pressure blocks peripheral vision.

How to Diagnose Pituitary Tumor ?

Three medical tests are needed to confirm a diagnosis of pituitary tumors.

1. Medical History & Physical Examination

   Doctors evaluate symptoms, hormone-related changes, and family medical history.

2. Hormone Testing

   Blood and urine tests measure hormone levels to assess tumor-related hormone production.

   Tests may include measurement of:

   • Prolactin
   • Growth hormone
   • Cortisol
   • ACTH
   • Thyroid hormones
   • LH and FSH

3. Imaging Tests

   The most important imaging test is magnetic resonance imaging (MRI) of the brain.

   MRI produces detailed images of the pituitary gland, enabling doctors to locate and measure the tumor.

   Some situations require CT scans.

4. Vision Tests

   Visual field testing becomes necessary because pituitary tumors can damage the optic nerves, thus causing vision loss.

What are the Treatment Options for Pituitary Tumor ?

The treatment process for pituitary tumors depends on factors such as tumor type and size, hormone production, and patient health status.

Observation

Doctors monitor small tumors through routine imaging and hormone assessments when patients show no symptoms.

Medication

The majority of pituitary tumors become treatable through medication.

For example, Dopamine agonists like cabergoline or bromocriptine effectively treat prolactinomas because they lower prolactin levels and can decrease tumor size.

The other medications control excessive hormone production from tumors that produce growth hormone or ACTH.

Surgery

Surgery requires the removal of the tumor when it results in severe symptoms or when medications prove ineffective.

Transsphenoidal surgery represents the primary surgical method in which surgeons use nasal pathways to extract tumors through specialized tools.

The procedure enables patients to recover more quickly by eliminating the need for a surgical opening in the skull.

Radiation Therapy

Radiation therapy may be used if:

• Surgery cannot completely remove the tumor.
• The tumor recurs after surgery.
• Surgery is not possible due to medical conditions.

Modern radiation techniques, such as stereotactic radiosurgery, allow exact radiation delivery to the tumor with the least amount of tissue harm possible.

What are the possible complications of Pituitary Tumors ?

Pituitary tumors that remain untreated result in multiple medical problems.

The conditions include:

• Permanent vision loss
• Hormonal deficiencies
• Infertility
• Osteoporosis
• Cardiovascular disease
• Diabetes

Timely diagnostic procedure and treatment can prevent many of these complications.

Why Long-Term Monitoring and Follow-Up needed ?

Patients who receive treatment for pituitary tumors need ongoing monitoring throughout their lives.

The follow-up process requires these actions:

• Periodic MRI scans
• Hormone level monitoring
• Vision testing

After treatment, some patients will require lifelong hormone replacement therapy because their pituitary gland has lost its ability to produce particular hormones.

What is Prognosis for Pituitary Tumors ?

The prognosis for pituitary tumors is usually good. This is because most of these tumors are benign.

Patients with small tumors who are diagnosed early usually have excellent prognoses. Even those with larger tumors can have good prognoses with surgery, medication, or radiation therapy.

Patients with pituitary tumors are living longer and enjoying a better quality of life thanks to advances in endocrinology and neurosurgery.
