Dsrct
Overview
DSRCTs (desmoplastic small round cell tumors) are a rare type of cancer. They usually start in the belly area but can sometimes develop in other parts of the body.
These cancers begin with a growth of abnormal cells. This growth often forms on the lining of the abdomen and pelvis, called the peritoneum. The cancer cells can spread quickly to nearby organs like the bladder, colon, and liver.
DSRCTs can affect anyone, but they are more frequently diagnosed in young men and boys.
Treating DSRCTs typically involves a combination of therapies, such as surgery, chemotherapy, and radiation therapy. This approach aims to control the cancer's growth and spread.
DSRCTs are classified as a type of soft tissue sarcoma. Soft tissue sarcomas are a group of cancers that start in the tissues that hold our bodies together, like tendons, ligaments, and fat. They support and surround other parts of the body.
Symptoms
Desmoplastic small round cell tumor (DSRCT) symptoms can differ based on where the cancer starts. Usually, it begins in the belly area. If DSRCT starts in the abdomen, you might notice:
- Belly swelling: This could be a gradual buildup of fluid or a noticeable increase in your belly's size.
- Belly pain: This pain can range from mild discomfort to sharp, intense pain. The location and type of pain might change over time.
- Constipation: Having trouble passing stool regularly is a common symptom.
- Problems urinating: Difficulty emptying your bladder or needing to urinate more often can be a sign.
If you experience any of these symptoms that last for a while and worry you, it's important to schedule an appointment with your doctor. Early diagnosis and treatment are key to managing this type of cancer.
When to see a doctor
If you're experiencing ongoing health problems that concern you, it's important to schedule a visit with your doctor or other healthcare professional. This includes any symptoms that don't go away or get worse over time. Don't ignore these feelings; talking to a healthcare provider is a good way to get answers and find the best course of action for your health.
Causes
Desmoplastic small round cell tumors (DSRCTs) are cancers, but scientists don't fully understand what causes them.
Cancer happens when a cell's DNA, which acts like a set of instructions for the cell, gets altered. These changes tell the cell to grow and divide much faster than normal. This rapid multiplication leads to a collection of abnormal cells forming a tumor. The tumor can grow and push into surrounding healthy tissue, damaging it. Sometimes, cancer cells can break off from the main tumor and travel to other parts of the body, where they can form new tumors, a process called metastasis. Exactly why these specific changes occur in the cells that lead to DSRCTs is still being researched.
Diagnosis
Diagnosing desmoplastic small round cell tumors (DSRCT) involves several steps to pinpoint the cancer's location, size, and characteristics.
Looking at the tumor: Doctors use imaging tests to see the tumor. These tests show the size and where the tumor is in your body. Some common imaging tests include:
- Ultrasound: Uses sound waves to create images.
- CT scan (Computed Tomography): Uses X-rays to create detailed cross-sectional images.
- MRI (Magnetic Resonance Imaging): Uses magnetic fields and radio waves to create detailed images, often offering more detailed information than CT scans.
- PET scan (Positron Emission Tomography): Uses radioactive substances to highlight areas of high activity in the body, which can sometimes show cancer.
Taking a tissue sample (biopsy): A crucial step is getting a small piece of the tumor tissue to examine under a microscope. This is called a biopsy. Your doctor might:
- Take a sample during surgery: If surgery is already planned, a piece of the tumor can be removed at the same time.
- Use a needle: A special needle can be inserted through the skin to collect a sample of the tumor cells. This procedure is sometimes done to avoid a larger surgery.
Lab tests: The tissue sample is sent to a lab. Scientists in the lab examine the cells under a microscope and run other tests. These tests can:
- Confirm the presence of cancer: The tests can determine if the abnormal cells are indeed cancer cells.
- Identify specific genetic changes: The lab tests can look for specific DNA changes within the cancer cells. These changes are unique to DSRCT and help differentiate it from other cancers.
- Guide treatment: The results of these tests help your doctor choose the best treatment plan for you. Understanding the exact type of cancer and any specific genetic changes is important for tailoring the most effective treatment.
By combining these imaging and tissue sample tests, doctors can accurately diagnose DSRCT and develop a personalized treatment plan.
Treatment
Desmoplastic Small Round Cell Tumor Treatment
Desmoplastic small round cell tumor (DSRCT) treatment varies based on your specific situation. Doctors consider where the cancer is located and if it has spread to other parts of the body. Most people with DSRCT need a combination of treatments.
Surgery: The goal of surgery is to remove all of the cancer. However, if the cancer has grown into nearby organs, complete removal might not be possible. In these cases, doctors might recommend chemotherapy first to shrink the tumor. If complete removal isn't possible, the surgeon will try to take out as much of the tumor as safely possible. After surgery, chemotherapy and radiation therapy may be used to kill any remaining cancer cells.
Chemotherapy: Chemotherapy uses powerful drugs to kill cancer cells. These drugs can be used before surgery to make the tumor smaller and easier to remove. Chemotherapy is also commonly used after surgery to kill any cancer cells that might have been left behind. If the cancer has spread, chemotherapy can help control symptoms like pain.
There are different ways chemotherapy can be delivered:
- Systemic Chemotherapy: This is the most common type. Drugs are injected into a vein, and they travel throughout the body, targeting fast-growing cells, including cancer cells. This approach works for DSRCT anywhere in the body.
- Regional Chemotherapy (HIPEC): For DSRCT in the abdomen, chemotherapy drugs can be given directly to the area around the abdominal organs (the peritoneal cavity). The drugs are heated and infused into the abdomen. This method, called hyperthermic intraperitoneal chemotherapy (HIPEC), is often used after surgery. It helps kill cancer cells in the abdomen.
Radiation Therapy: Radiation therapy uses high-energy beams (like X-rays or protons) to kill cancer cells. You lie still on a table while a machine moves around you, targeting the radiation to specific areas of the cancer. Radiation may be used after surgery to destroy any remaining DSRCT cells in the abdomen. If the cancer has spread, radiation therapy might be used to help manage pain or other symptoms.
Targeted Therapy: Targeted therapies are drugs that attack specific molecules within cancer cells. By blocking these molecules, the drugs can cause the cancer cells to die. Targeted therapy might be an option if the cancer comes back after other treatments or if it has spread. Your doctor may test your cancer cells to see if a specific targeted therapy is likely to work. Targeted therapy can be used alone or combined with chemotherapy.
Coping with a Cancer Diagnosis:
Being diagnosed with cancer can be very stressful. It's important to remember that you're not alone. Here are some ways to cope:
- Learn about your cancer: Ask your doctor lots of questions about your specific type of cancer, treatment options, and prognosis. The more you know, the more confident you'll feel about making decisions about your care.
- Lean on your support system: Stay connected with friends and family. They can provide practical help (like taking care of your home) and emotional support during difficult times.
- Talk to someone: Talking about your hopes and fears with a friend, family member, counselor, medical social worker, clergy member, or a cancer support group can be very helpful.
Finding support groups in your area or connecting with organizations like the National Cancer Institute or the American Cancer Society can also provide valuable resources and emotional support.
