Prepare to be enlightened, as we delve into the intriguing world of granulosa-stromal cell tumors and discover the secrets they hold.
granulosa-stromal cell tumor
Granulosa-stromal cell tumors, also known as granulosa-theca cell tumors (GCTs), are a type of ovarian tumor.
These tumors are generally of low malignant potential, with approximately 90% being diagnosed at stage I.
The 10-year survival rate for stage I GCTs in adults is between 90-96%.
However, more advanced stages of GCTs are associated with lower survival rates, with 5- and 10-year survival rates ranging from 33-44%.
Overall, the 5-year survival rates for adult-type granulosa cell tumors (AGCTs) and juvenile-type granulosa cell tumors (JGCTs) are 90% and 95-97%, respectively.
The recurrence rate for AGCTs is 43%, occurring an average of 5 years after treatment, while JGCTs tend to recur within the first 2 years.
Factors such as tumor stage, mitotic rates, atypia, rupture of the capsule, and tumor size are associated with poorer prognosis.
Treatment of GCTs often leads to regression of physical changes caused by high estrogen levels, and the morbidity of the disease is primarily due to endocrine manifestations.
However, some patients may experience symptoms of androgen excess, and there is an increased risk of endometrial hyperplasia and adenocarcinoma.
Chemotherapy is generally well-tolerated, and the overall survival rate after recurrence is approximately 5 years.
Despite treatment, approximately 20% of patients diagnosed with GCTs still die from the disease.
Key Points:
- Granulosa-stromal cell tumors are a type of ovarian tumor with generally low malignant potential.
- 90% of these tumors are diagnosed at stage I, with a 10-year survival rate of 90-96%.
- More advanced stages of GCTs have lower survival rates ranging from 33-44%.
- Adult-type granulosa cell tumors (AGCTs) have a 5-year survival rate of 90%, while juvenile-type granulosa cell tumors (JGCTs) have a 5-year survival rate of 95-97%.
- AGCTs have a recurrence rate of 43% after an average of 5 years, while JGCTs tend to recur within the first 2 years.
- Factors such as tumor stage, mitotic rates, atypia, rupture of the capsule, and tumor size are associated with poorer prognosis.

Pro Tips:
1. Granulosa-stromal cell tumors most commonly affect women of reproductive age, typically between 40 and 60 years old.
2. These tumors have a unique characteristic called “Call-Exner bodies,” which are small follicles filled with eosinophilic fluid that form within the tumor.
3. Compared to other types of ovarian tumors, granulosa-stromal cell tumors are often associated with hormonal imbalances, such as excessive estrogen production, leading to symptoms like abnormal uterine bleeding and menstrual irregularities.
4. Granulosa-stromal cell tumors have low malignant potential and are usually considered borderline or low-grade malignant tumors. However, they can rarely metastasize to other parts of the body.
5. Genetic mutations and syndromes, such as the DICER1 gene mutation and Peutz-Jeghers syndrome, have been linked to an increased risk of developing granulosa-stromal cell tumors in some cases.
1. Introduction: Granulosa-Theca Cell Tumors And Their Malignant Potential
Granulosa-theca cell tumors (GCTs) are the most common type of sex cord-stromal tumor found in individuals assigned female at birth and are primarily located in the ovaries. Although these tumors can be malignant, they typically exhibit slow growth and are frequently diagnosed in the early stages. This early detection contributes to favorable treatment outcomes.
GCTs consist of two types of cells, namely granulosa and theca cells, both of which play crucial roles in the production of estrogen and regulation of the menstrual cycle. Compared to other ovarian tumors, GCTs have a relatively low malignant potential, with approximately 90% of cases being diagnosed at stage I.
Some key points to highlight about Granulosa-theca cell tumors (GCTs) include:
- GCTs are the most common type of sex cord-stromal tumor found in individuals assigned female at birth and are primarily located in the ovaries.
- While GCTs can be malignant, they typically grow slowly and have a high chance of being diagnosed at an early stage.
- Their slow growth and early detection contribute to favorable treatment outcomes.
- GCTs are composed of granulosa and theca cells, which are responsible for estrogen production and regulation of the menstrual cycle.
- Compared to other ovarian tumors, GCTs have a relatively low malignant potential, with approximately 90% of cases being diagnosed at stage I.
“GCTs have a relatively low malignant potential compared to other ovarian tumors, with approximately 90% of cases diagnosed at stage I.”
- Granulosa and theca cells produce estrogen and regulate the menstrual cycle.
- Early diagnosis is key to successful treatment outcomes.
2. Stage I GCTs At The Time Of Diagnosis
Stage I GCTs account for approximately 90% of cases at the time of diagnosis. This early stage is characterized by the tumor being confined to the ovary without evidence of spread to other pelvic or abdominal structures. The favorable prognosis of stage I GCTs is primarily attributed to the localized nature of the tumor and the absence of metastasis.
3. 10-Year Survival Rates For Stage I GCTs In Adults
For adults diagnosed with stage I GCTs, the 10-year survival rate ranges from 90% to 96%. This high survival rate reflects the overall favorable prognosis for these patients. It is important to note that these survival rates represent an average and individual outcomes may vary depending on various factors such as tumor characteristics and patient-specific factors.
- The 10-year survival rate for adults with stage I GCTs is between 90% and 96%.
- This high survival rate demonstrates a favorable prognosis for these patients.
- Individual outcomes may vary due to factors like tumor characteristics and patient-specific factors.
“These survival rates represent an average and individual outcomes may vary depending on various factors.”
4. Survival Rates For GCTs Of Advanced Stages
Advanced-stage GCTs have lower survival rates (33% to 44%) compared to stage I tumors. This emphasizes the significance of early detection and treatment interventions in improving outcomes for individuals with GCTs.
5. Overall 5-Year Survival Rates For Different Types Of GCTs
The 5-year survival rates for patients with adult-type granulosa cell tumors (AGCTs) or juvenile-type granulosa cell tumors (JGCTs) are generally favorable. AGCTs have a survival rate of 90%, while JGCTs have a slightly higher range of 95% to 97%. These high survival rates indicate that both types of GCTs have a good prognosis and respond well to available treatment options.
6. Survival Rates And Recurrence Rate For Adult-Type Granulosa Cell Tumors (AGCTs)
AGCTs, a subtype of GCTs, have a 10-year survival rate of approximately 76%. While this survival rate is lower compared to the overall 5-year survival rate, it still demonstrates a favorable prognosis for AGCT patients.
However, an important aspect to consider is the recurrence rate, which is 43% in stage I-III AGCT patients observed over 10 years. This highlights the importance of long-term follow-up care to monitor for recurrent disease.
- AGCTs have a 10-year survival rate of approximately 76%
- Recurrence rate in stage I-III AGCT patients is 43% over 10 years.
“Long-term follow-up care is essential to monitor for recurrent disease.”
7. Recurrence Patterns And Survival After AGCT Recurrence
AGCTs, or adult granulosa cell tumors, usually recur about 5 years after the initial treatment. Interestingly, over 50% of the recurrences happen after the 5-year mark. After a recurrence, the average survival time is 5 years, and the overall survival rate over a 10-year period ranges from 50% to 60%. These findings underscore the importance of ongoing monitoring and surveillance, even after successful treatment of AGCTs.
8. Prognostic Variables And Factors Associated With Poorer Prognosis
The tumor stage at the time of initial surgery is considered the most important prognostic variable for GCTs. Other factors associated with a poorer prognosis include:
- High mitotic rates
- Moderate-to-severe atypia
- Preoperative spontaneous rupture of the capsule
- Tumors larger than 15 cm
These factors indicate more aggressive tumor behavior and the potential for worse outcomes.
9. Survival Rates And Characteristics Of True Thecomas
True thecomas, which are a subtype of GCTs, have a 5-year survival rate of nearly 100%. This indicates an excellent prognosis for individuals with this specific type of GCT. True thecomas are rare and typically have benign behavior, contributing to their favorable survival rates.
10. Morbidity, Endocrine Manifestations, And Treatment Outcomes In GCTs
Morbidity in granulosa cell tumors (GCTs) primarily arises from the endocrine manifestations of the disease. High estrogen levels caused by unopposed estrogen production may lead to various physical changes, such as abnormal bleeding and endometrial hyperplasia. Approximately 30% to 50% of patients develop endometrial hyperplasia, and 8% to 33% may develop endometrial adenocarcinoma.
Patients with GCTs may also be at an increased risk for breast cancer, although establishing a direct correlation is challenging.
Treatment outcomes for GCTs are generally favorable, and removal of the tumor through surgery regresses the physical changes caused by high estrogen levels. Chemotherapy, when required, is usually well-tolerated, and adverse effects are expected. The overall high survival rates for most types of GCTs, especially when diagnosed at early stages, emphasize the importance of prompt diagnosis and appropriate management strategies.
- High estrogen levels caused by unopposed estrogen production
- Abnormal bleeding and endometrial hyperplasia
- Increased risk for breast cancer
- Treatment outcomes are generally favorable
- Surgery regresses physical changes caused by high estrogen levels
- Chemotherapy is usually well-tolerated
- High survival rates for most types of GCTs, especially when diagnosed early

You may need to know these questions about granulosa-stromal cell tumor
What is the survival rate of granulosa cell tumor?
Granulosa cell tumors (GCTs) have a generally favorable prognosis, with a high survival rate depending on the stage of the tumor. When diagnosed at stage I, which is the case for about 90% of GCTs, the 10-year survival rate in adults ranges from 90-96%. This suggests that patients with stage I GCTs have a strong likelihood of long-term survival. However, for GCTs diagnosed at more advanced stages, the 5- and 10-year survival rates drop significantly to 33-44%. This highlights the importance of early detection and treatment in order to improve the chances of survival for patients with GCTs at advanced stages.
Is granulosa cell tumor aggressive?
Granulosa cell tumor (GCT) is typically considered to have an indolent clinical course, with delayed recurrence and good overall survival for early-stage cases. However, it is important to note that a few cases of aggressive adult GCT have been reported. While most AGCTs display a relatively benign behavior, these rare aggressive variants may exhibit more rapid progression and poorer outcomes. Consequently, careful monitoring and individualized treatment strategies should be employed to effectively manage these atypical cases.
Is granulosa cell tumor curable?
Granulosa cell tumors, fortunately, have a good prognosis in terms of curability. Surgery has been found to effectively treat these tumors, particularly when they are detected and removed at an early stage. By promptly removing the tumors through surgery, patients have a high chance of being cured and regaining their health.
What type of ovarian cancer is granulosa cell tumor?
Granulosa cell tumors of the ovary are a type of sex cord stromal tumor, representing a small percentage of overall ovarian neoplasms. Despite their rarity, they are the most common form of sex cord stromal tumor. Typically, they are diagnosed in the early stages, leading to a more positive prognosis for the majority of patients.
