Gestational trophoblastic disease (GTD) is a rare group of neoplastic diseases that arise from the trophoblast cells that form the placenta during pregnancy. This pathological process can manifest itself in different forms, the most well-known of which is the hydatid form, or molar pregnancy. GTD can occur against the background of a normal pregnancy or as a consequence of pregnancy failure. The disease is characterized by abnormal proliferation of trophoblastic cells, which can lead to the formation of tumors, both benign and malignant, and is accompanied by various clinical manifestations, including bleeding, increased levels of human chorionic gonadotropin (hCG), and reproductive system disorders. It is important to note that GTD requires careful diagnosis and monitoring, since in some cases it can lead to serious complications, including tumor metastasis.
History of the disease and interesting historical facts
The history of studying gestational trophoblastic disease goes back more than a century. The first cases of molar pregnancy were described in the early 20th century, but it was not until the 1930s that significant progress was made in understanding its pathogenesis. Scientists such as Becker and Wagner made important contributions to the study of this disease by identifying specific morphological and clinical characteristics. During the 1960s, diagnostic and treatment methods for GTB began to be actively developed, which significantly improved the results. One of the key moments in history was the introduction of the ability to monitor hCG levels, which ensured more accurate monitoring of the disease and timely intervention. Interestingly, until the early 1970s, GTB was considered fatal in most cases, but modern treatment methods such as chemotherapy have dramatically changed the prognosis for patients.
Epidemiology
According to current epidemiological data, gestational trophoblastic disease occurs with a frequency of 1 in 1000–2000 pregnancies. Prevalence varies depending on geographic region, ethnicity, and socioeconomic conditions. For example, in countries with developed health care systems, the incidence is generally lower than in developing countries, where access to health care may be limited. In contrast, among women with high fertility, such as in some African and Asian populations, the incidence of GTB may reach 1 in 500 pregnancies. It is also noted that the risk of GTB is increased in patients who have previously had molar pregnancies, which emphasizes the importance of regular screening and monitoring after previous cases.
Genetic predisposition to this disease
Although the exact causes of gestational trophoblastic disease are not fully understood, a link between genetic factors and pathology has been identified. Pathological changes may be associated with chromosomal abnormalities, such as triploidy, which is common in the hydatid form. Some studies suggest that mutations in genes responsible for cell proliferation and apoptosis may increase the risk of developing GTB. In particular, newly identified genetic markers, such as P53, play an important role in regulating the cell life cycle and may be involved in the pathogenesis of this disease. However, a significant proportion of GTB cases are spontaneous, indicating that the exact mechanisms of disease development are insufficiently understood.
Risk factors for the development of this disease
There are several factors that increase the risk of developing gestational trophoblastic disease. The main ones include:
- Previous molar pregnancies - women who have previously had a molar pregnancy have a 10-fold increased risk of recurrence.
- Age - the risk is higher in women over 35 and under 20.
- Number of pregnancies - An increase in the number of pregnancies is also considered a risk factor.
- Health conditions - Having certain medical conditions, such as diabetes or hypertension, can negatively affect the outcome of pregnancy.
- Smoking and alcohol consumption are factors that can reduce overall reproductive capacity and contribute to the development of pathology.
Identification and investigation of risk factors is important for the development of preventive measures and disease management.
Diagnosis of this disease
Diagnosis of gestational trophoblastic disease includes a comprehensive examination based on clinical signs, laboratory tests and radiological diagnostics. The main symptoms of GTB include:
- Vaginal bleeding in early pregnancy.
- An increase in the size of the uterus, exceeding the norm for a given period.
- High hCG levels in blood tests.
Laboratory tests focus on assessing the level of human chorionic gonadotropin, which may remain elevated even after the pregnancy is over. Radiological examinations, such as pelvic ultrasound, help visualize changes in the structure of the uterus and identify abnormal formations. It is also important to conduct a differential diagnosis, excluding other pathologies, such as ectopic pregnancy or abortion, which ensures accuracy and early intervention in the treatment process.
Treatment
Treatment for gestational trophoblastic disease depends on the stage of the disease and its form. The main treatment methods include:
- General treatment - monitoring the patient's condition and examination for relapses play an important role.
- Pharmacological treatment - in case of malignant form of GTB, chemotherapy drugs such as methotrexate or dactinomycin are used.
- Surgical treatment - may include surgery to remove the uterus or control surgery to remove abnormal tissue.
- Additional methods - in some cases, the use of radiation therapy may be recommended.
Timely seeking of medical help and adequate therapy are the key to successful treatment and can significantly improve the prognosis for the patient.
List of medications used to treat this disease
- Methotrexate - used to treat molar pregnancy and highly differentiated forms of GTB.
- Dactinomycin is used for more aggressive forms of the disease.
- Platinum chemotherapy - provides effective treatment for patients with relapses.
- Anti-inflammatory medications - may be prescribed to relieve symptoms.
Disease monitoring
Monitoring of patients after treatment for gestational trophoblastic disease is an important part of follow-up care. Key monitoring steps include regular blood tests for hCG levels, ultrasound examinations, and examinations for metastases. The prognosis is favorable in many cases, especially with early diagnosis and adequate therapy. However, it is important to remember the possibility of recurrence of the disease, which may require further treatment. Complications such as metastasis can significantly worsen the prognosis, especially if vital organs are involved.
Age-related features of the disease
Gestational trophoblastic disease can manifest itself in different age groups, but there are some peculiarities. In adolescents and young women, the disease most often manifests itself in the form of molar pregnancy, while in older women, the risk of malignant progression increases. These age groups require special attention and approach not only in diagnosis, but also in terms of treatment and monitoring. Each group may experience different physical and psychological consequences, which should be taken into account when developing individual examination plans and therapeutic measures.

Advice from Dr. Oleg Korzhikov
Taking into account the main questions that patients often have, Dr. Oleg Korzhikov offers several pieces of advice. First of all, it is important to monitor your condition at all stages of pregnancy, especially if there are previous cases of GTB. Regular examinations will help to identify pathology at an early stage. Next, you should pay attention to any changes in your health, such as bleeding or unusual pain. You should not self-medicate or postpone a visit to the doctor if alarming symptoms appear. In conclusion, the doctor emphasizes the importance of supporting loved ones and consulting a psychologist during pregnancy with a high risk of GTB.
