Granulosa Cell Tumor
Disease Details
Family Health Simplified
- Description
- Granulosa cell tumor is a rare type of ovarian cancer that arises from the granulosa cells, which are involved in the production of estrogen.
- Type
- Granulosa cell tumor is a type of ovarian tumor. It is typically not inherited and is considered sporadic rather than associated with a specific type of genetic transmission.
- Signs And Symptoms
-
Granulosa cell tumors are a type of ovarian tumor characterized by several signs and symptoms, which may include:
1. **Abdominal Distension and Pain**: Often due to the mass effect of the tumor.
2. **Irregular Menstrual Cycles**: Including heavy bleeding (menorrhagia) or missed periods (amenorrhea).
3. **Postmenopausal Bleeding**: Unnatural bleeding in postmenopausal women.
4. **Pelvic Pain or Pressure**: Discomfort in the lower abdomen.
5. **Hormonal Symptoms**: Because these tumors can secrete estrogen, symptoms might include breast tenderness, early puberty in children, or other signs of increased estrogen levels.
If you are experiencing any of these symptoms, it's important to seek medical evaluation for an accurate diagnosis and appropriate treatment. - Prognosis
- Granulosa cell tumors (GCTs) are a type of ovarian tumor. The prognosis for GCTs generally depends on factors such as the stage at diagnosis, patient age, and tumor histology. Early-stage GCTs, particularly those confined to the ovary (stage I), typically have a favorable prognosis with high survival rates. Advanced-stage disease or recurrent tumors may have a poorer prognosis. The overall survival rate remains relatively high compared to other ovarian cancers, and long-term follow-up is recommended due to the potential for late recurrences.
- Onset
- Granulosa cell tumors are typically found in adults, with the majority occurring in postmenopausal women, although they can also appear in younger women and adolescents. The onset of these tumors can be insidious, often presenting with symptoms related to hormone production such as abnormal uterine bleeding, abdominal pain or distension, and signs of estrogen excess.
- Prevalence
- The prevalence of granulosa cell tumor (GCT) of the ovary is relatively low, accounting for approximately 2-5% of all ovarian tumors.
- Epidemiology
- Granulosa cell tumors (GCTs) are a rare type of ovarian tumor, comprising approximately 2-5% of all ovarian malignancies. They are considered sex cord-stromal tumors and are most commonly diagnosed in postmenopausal women, although they can occur at any age. The incidence rate is relatively low, with about 0.6 to 1.6 cases per 1 million women annually.
- Intractability
- Granulosa cell tumors, a type of ovarian cancer, are not inherently intractable but can be challenging to treat, especially if diagnosed at later stages or if recurrent. Early-stage tumors often have a good prognosis with surgical intervention, sometimes followed by chemotherapy. Recurrent or advanced cases may require more aggressive and ongoing treatment, making management more complex. Regular monitoring and follow-up are essential for managing this condition.
- Disease Severity
-
Granulosa cell tumor is a rare type of ovarian tumor that arises from the granulosa cells, which are involved in hormone production within the ovaries. The severity of the disease can vary:
- **Early-stage**: When detected early, the tumor is often localized and can be effectively treated with surgery.
- **Advanced-stage**: If the tumor has spread, it may require additional treatments like chemotherapy. Advanced stages can be more challenging to treat and may have a worse prognosis.
Regular follow-up is necessary as these tumors have a tendency for late recurrence. - Healthcare Professionals

- Pathophysiology
-
Granulosa cell tumors (GCTs) are a type of ovarian neoplasm derived from the granulosa cells, which are involved in the production of sex hormones and are crucial in the development of ovarian follicles. The pathophysiology of GCTs primarily involves uncontrolled proliferation of these granulosa cells.
Key features of the pathophysiology:
1. **Hormone Secretion:** GCTs often secrete estrogens, leading to hyperestrogenism. This hormonal imbalance can result in symptoms such as abnormal uterine bleeding, endometrial hyperplasia, and increased risk of endometrial carcinoma.
2. **FOXL2 Mutation:** A specific point mutation (402C→G) in the FOXL2 gene is present in a high percentage of adult-type GCTs. FOXL2 is a transcription factor important for granulosa cell development and function.
3. **Tumor Growth and Invasion:** Like other malignancies, GCTs have the ability to grow locally within the ovary and can invade surrounding tissues. Metastasis, although rare, can occur, spreading to the abdominal cavity, lymph nodes, and distant organs.
4. **Stromal Involvement:** The tumor stroma is typically composed of theca cells, which can also contribute to the hormonal milieu by producing androgens, which are then converted to estrogens by the granulosa cells.
Nan (Not applicable/not noted): As "nan" typically stands for not a number or could mean not applicable, it does not apply to the pathophysiology description of granulosa cell tumors. If further context regarding "nan" in relation to GCT is provided, more specific information can be given. - Carrier Status
- Granulosa cell tumors are not typically associated with a carrier status, as they are not known to be inherited in a way that would involve carriers.
- Mechanism
-
Granulosa cell tumors (GCTs) are a type of ovarian sex cord-stromal tumor. They can be classified into adult and juvenile types. Their development involves several key molecular mechanisms:
1. **FOXL2 Mutation**: The FOXL2 gene mutation (402C→G, leading to the amino acid substitution C134W) is found in about 97% of adult-type GCTs. This mutation plays a crucial role in tumor pathogenesis, affecting cell proliferation and survival.
2. **Wnt/Beta-Catenin Signaling**: Dysregulation of the Wnt/beta-catenin pathway has been implicated in GCTs. Abnormal activation of this signaling pathway can promote tumorigenesis by influencing cell fate, proliferation, and migration.
3. **TGF-β Signaling**: Transforming growth factor-beta (TGF-β) signaling is involved in the regulation of granulosa cell function and differentiation. Alterations in this pathway may contribute to the development and progression of GCTs.
4. **Hormonal Influence**: GCTs may secrete estrogens, inhibins, and other hormones, which can influence tumor growth through autocrine and paracrine mechanisms.
5. **Molecular Pathways**: Other reported molecular alterations include those affecting the PI3K/AKT/mTOR pathway, which is involved in cell growth and survival, and the ERK/MAPK pathway, which influences cell differentiation and proliferation.
Understanding these mechanisms provides insights into potential therapeutic targets and diagnostic markers for granulosa cell tumors. - Treatment
-
Granulosa cell tumor treatment options typically include:
1. **Surgery**: This is the primary treatment and involves the removal of the tumor. The extent of surgery depends on whether the tumor has spread.
2. **Chemotherapy**: Often used if the tumor has spread or recurred after surgery. Common chemotherapeutic agents include platinum-based drugs.
3. **Radiotherapy**: May be considered in certain cases, but it is less common for granulosa cell tumors.
4. **Hormonal Therapy**: This includes the use of medications such as aromatase inhibitors, which may be effective due to the hormone-sensitive nature of some granulosa cell tumors.
No additional treatment-related information is available right now (nan). - Compassionate Use Treatment
-
Granulosa cell tumors (GCTs) are a rare type of ovarian tumor. Compassionate use treatments and off-label or experimental therapies for GCT may include the following:
1. **Hormonal therapies**: Medications such as aromatase inhibitors (e.g., letrozole or anastrozole) or GnRH agonists (e.g., leuprolide) might be considered, as GCTs can be hormone-sensitive.
2. **Targeted therapies**: There is ongoing research into the use of targeted therapies for GCT, such as anti-angiogenic agents (e.g., bevacizumab) or PARP inhibitors.
3. **Chemotherapy**: While not typically first-line for GCTs, off-label use of chemotherapeutic agents like platinum-based compounds (e.g., carboplatin) or taxanes (e.g., paclitaxel) may be considered, especially in cases of recurrent or advanced disease.
4. **Clinical Trials**: Patients might be eligible for clinical trials exploring new drugs or combinations of treatments specifically targeting GCTs.
It's important to work with a specialized oncology team to explore these options and determine the most appropriate course of action. - Lifestyle Recommendations
-
For individuals with granulosa cell tumor, lifestyle recommendations may include:
1. **Regular Medical Follow-up**: Regular visits to your oncologist are crucial for monitoring the tumor and assessing the effectiveness of treatment.
2. **Balanced Diet**: A diet rich in fruits, vegetables, whole grains, lean proteins, and low in processed foods can support overall health and potentially aid recovery.
3. **Exercise**: Regular physical activity, as recommended by your healthcare provider, can help improve energy levels, mood, and overall physical health.
4. **Stress Management**: Engage in stress-reducing activities such as yoga, meditation, or hobbies to maintain mental and emotional well-being.
5. **Avoid Smoking and Limit Alcohol**: Avoiding tobacco and limiting alcohol intake are general recommendations to reduce cancer risk and support health.
6. **Stay Informed**: Educate yourself about your condition and stay updated on new research or treatments.
7. **Support System**: Engage with support groups or counseling services to help navigate emotional and psychological challenges.
Consult with your healthcare provider for personalized advice tailored to your specific condition and treatment plan. - Medication
- Granulosa cell tumors are a type of ovarian tumor. The primary treatment is usually surgical removal of the tumor. Medication plays a less significant role compared to surgery, but postoperative treatment options might include hormone therapy or chemotherapy, depending on the stage and nature of the tumor. Medications such as bleomycin, etoposide, and cisplatin (BEP regimen) are sometimes used in chemotherapy for malignant cases. Hormonal therapies may include agents like GnRH analogs, aromatase inhibitors, or progestins. Always consult with a healthcare provider for personalized treatment options.
- Repurposable Drugs
-
Granulosa cell tumors (GCTs) are rare ovarian tumors that generally represent a subset of sex cord-stromal tumors. Research into repurposable drugs for treating granulosa cell tumors is ongoing, and some drugs have shown potential in various studies. These may include:
1. **Aromatase Inhibitors** (e.g., letrozole, anastrozole) - These drugs are typically used in breast cancer treatment and may help by reducing estrogen levels, which can feed tumor growth.
2. **GnRH Agonists** (e.g., leuprolide) - These agents can suppress ovarian steroidogenesis and have potential in managing hormonally responsive GCTs.
3. **SERMs (Selective Estrogen Receptor Modulators)** (e.g., tamoxifen) - Used in breast cancer, they may be effective in tumors that express estrogen receptors.
4. **MEK Inhibitors** (e.g., trametinib) - Targeting the MAPK pathway, which is often activated in GCTs, may offer therapeutic benefits.
These drugs are not currently specific for granulosa cell tumors but may offer potential benefits given their mechanisms of action. Clinical trials are crucial for establishing their efficacy and safety in this particular context. - Metabolites
-
Granulosa cell tumors (GCTs) are a rare type of ovarian tumor originating from granulosa cells. Specific metabolites associated with GCTs are not well-documented or universally agreed upon due to the rarity and variability of the condition. However, some potential metabolic markers and related substances may include:
1. **Inhibin:** A hormone produced by granulosa cells which is often elevated in patients with GCTs.
2. **Estrogen:** GCTs can secrete estrogen, leading to symptoms associated with hyperestrogenism.
3. **Anti-Müllerian Hormone (AMH):** Often elevated in GCTs and used as a tumor marker.
In terms of direct metabolic profiling, research is ongoing, and specific metabolites are still being investigated.
"NAN" seems to refer to a non-available or non-applicable category, indicating that specific detailed metabolic data might not be accessible or applicable for this condition. - Nutraceuticals
- There are no widely recognized nutraceuticals specifically proven to treat granulosa cell tumors effectively. Treatment typically involves surgery, and sometimes additional therapies like radiation or chemotherapy. Always consult with a healthcare provider for personalized recommendations.
- Peptides
- Granulosa cell tumors (GCTs) are a type of ovarian tumor that arise from the granulosa cells. These tumors can produce hormones, including peptides such as inhibin and anti-Müllerian hormone (AMH), which can serve as biomarkers for diagnosis and monitoring. The term "nan" (not a number) is often used in programming and data analysis to signify missing or undefined data; in a medical context, it does not typically apply directly to the disease itself.
