About Desmoplastic Small Round Cell Tumors
Desmoplastic Small Round Cell Tumors (DSRCT) are caused by a specific genetic change involving a translocation between chromosomes 11 and 22. This genetic change occurs during a person's lifetime and is not inherited. The translocation causes the EWS gene to join with the WT1 region, leading to abnormal cell growth and division that damages tissue.
As for the risk factors of DSRCT, here are the non-modifiable and modifiable factors:
Non-modifiable risk factors:
Age: DSRCT primarily affects children and young adults.
Gender: It is more common in males.
Modifiable risk factors:
Exposure to certain chemicals or toxins: Although specific substances have not been identified as direct causes of DSRCT, exposure to certain chemicals or toxins may increase the risk of developing cancer in general. Avoiding exposure to harmful substances is always advised.
Lifestyle choices: While there are no specific lifestyle factors directly linked to DSRCT, maintaining a healthy lifestyle can help reduce the overall risk of developing cancer.
It's important to note that these risk factors are based on general observations, and individual cases may vary. If you have concerns about your risk for DSRCT, it's best to consult with your healthcare professional for personalized advice.
Desmoplastic Small Round Cell Tumors (DSRCT) may not cause symptoms in the early stages. However, as the tumors grow larger, the following symptoms may occur:
Early Symptoms:
- Pain
- Nausea and vomiting
- Diarrhea
- Constipation
- Swelling in the abdomen
Later stage, progression, or higher severity of DSRCT may lead to additional symptoms such as:
- Abdominal mass
- Gastrointestinal obstruction (such as constipation)
- Acute renal failure (due to tumor growth and compression)
It's important to note that these symptoms can vary among individuals, and not everyone may experience the same symptoms. If you are experiencing any concerning symptoms or have any concerns about DSRCT, it is recommended to consult with a healthcare professional for an accurate diagnosis and appropriate management.
To diagnose Desmoplastic Small Round Cell Tumors (DSRCT), the following examinations, tests, and procedures are commonly performed:
Physical Exam: The healthcare provider will look for physical signs such as pain, swelling, or the presence of masses in the body.
Lab Tests: Specific lab tests, such as blood draws, may be recommended to check for abnormalities.
Imaging Studies: Imaging scans like ultrasound, CT, MRI, and PET are used to locate and assess the size of tumors. They also help determine if the tumor has spread to other parts of the body.
Biopsy: A small sample of the tumor is taken using a needle during a biopsy. A pathologist then examines the cells under a microscope to identify the type of tumor.
To determine the stage or severity of DSRCT, additional examinations, tests, and procedures may include:
Further Imaging Studies: Additional imaging studies may be performed to assess the extent of tumor spread and involvement in nearby organs or lymph nodes.
Molecular Testing: Molecular tests can be done to identify specific genetic mutations or markers that may guide treatment decisions.
Staging Procedures: Depending on the individual case, staging procedures such as laparoscopy or exploratory surgery may be recommended to further evaluate the extent of tumor involvement.
It's important to consult with your healthcare provider who can provide personalized recommendations based on your specific situation.
The goals of treatment for Desmoplastic Small Round Cell Tumors (DSRCT) are to:
Remove as much of the tumor as possible through surgery to reduce the tumor burden and improve outcomes.
Kill cancer cells that have spread to other parts of the body using chemotherapy, which is a medication that targets and destroys cancer cells.
Target the tumor cells in the abdomen specifically using Hyperthermic Intraperitoneal Chemotherapy (HIPEC). This procedure washes the inside of the abdomen with warm chemotherapy drugs, killing tumor cells without exposing the rest of the body to the drugs.
Kill cancer cells using radiation therapy, which uses radiation to destroy cancer cells either from an external machine or by placing radiation sources inside or near the tumor.
To achieve these treatment goals, the following approaches are recommended:
- Surgery: Remove as much of the tumor as possible.
- Chemotherapy: Administer medication that targets and kills cancer cells throughout the body.
- HIPEC: Perform a procedure that washes the inside of the abdomen with warm chemotherapy drugs specifically targeting tumor cells in that area.
- Radiation Therapy: Use radiation to kill cancer cells either externally or internally.
It's important to note that each treatment option has its own mechanisms and potential side effects. Consult with your healthcare professional for personalized advice regarding medication types, therapies, therapeutic procedures, health behavior changes, or other treatments for DSRCT.
Medication dosing may be affected by many factors. Check with your health care professional about dosing for your individual situation.
Other side effects can occur. Check with your health care professional or read the information provided with your medication for additional side effect information.
