Malignant fibrous histiocytoma (MFH) is a rare cancer that affects soft tissues. It mainly impacts muscles and tendons but can also show up in bones. This is not as common, though.
MFH/UPS is a fast-moving cancer that spreads to different body parts. It might come back after treatment, with a 13-42% chance. It mostly affects older and middle-aged adults. It’s quite rare in children. Symptoms can include pain and swelling in bones, joint pain, and finding a soft or warm lump.
The exact reasons behind MFH/UPS are still not clear. However, it’s thought that getting older or having radiation therapy before might raise your chances. Doctors check for this cancer through physical exams, X-rays, MRIs, and biopsies. They look at tissue samples to see if there are cancer cells.
Treatments for MFH can involve surgery, chemotherapy, radiation therapy, and targeted therapy. There’s also a new method using stem cells that scientists are looking into.
Key Takeaways
- Malignant fibrous histiocytoma (MFH) is a rare type of cancer that primarily affects soft tissues such as muscles and tendons.

- Common symptoms of MFH include bone pain and swelling, joint pain, and the presence of a soft or warm lump.
- The exact causes of MFH are unknown, but age and previous radiation therapy may increase the risk.
- Diagnosis involves physical exams, imaging tests, and a biopsy to analyze tissue samples for cancer cells.
- Treatment options for MFH include surgery, chemotherapy, radiation therapy, and targeted therapy.
- Stem cell therapy is being investigated as a potential novel treatment option for MFH.
Understanding Undifferentiated Pleomorphic Sarcoma (UPS)
Undifferentiated pleomorphic sarcoma (UPS) is a very aggressive cancer. Its old name was malignant fibrous histiocytoma (MFH). UPS can grow in different parts of the body. It spreads easily to other places.
We don’t know for sure what causes UPS. But, scientists think it starts from a type of cell called mesenchymal stem cells. Changes in genes, how cells signal, and radiation can lead to UPS.
It’s more common in older people and affects men more than women. White men get UPS more often than black men.
Epidemiology
UPS is not common, making up about 1-2% of soft-tissue cancers. It’s typically found in adults over 50.
Men tend to get it more than women. Whites are a bit more likely to have UPS than black people.
Histopathology and Evaluation
A close look under a microscope is key to diagnosing UPS. Doctors see unique cells that show it’s UPS and not another cancer.
Special tests check for certain proteins to confirm UPS. This helps doctors know the best way to treat it.
Tests like scans help find out how far the cancer has spread. This helps doctors plan the right treatment and surgery.
Treatment
Surgery is the main treatment. The goal is to cut out the cancer with enough healthy tissue around it. If surgery can’t completely remove the cancer, radiation might be done. This kills any leftover cancer cells.
Chemo might also be used. But it’s more for cases where the cancer has spread. The doctors choose treatments based on many factors. They work together to give the best care.
Dealing with UPS is hard. But early diagnosis and the right care can help. Research is ongoing to find better treatments for UPS.
Management and Treatment of Malignant Fibrous Histiocytoma
Managing and treating malignant fibrous histiocytoma (MFH) involves several key factors. These factors depend on the patient’s age, tumor’s severity and location, and whether it has spread. Doctors use this info to create a treatment plan that fits each person.
Surgery is often the main treatment for MFH. Its goal is to remove the cancer and stop it from spreading. Doctors may need to take out the tumor and some surrounding tissue. This helps ensure a good outcome.
Other treatments like chemotherapy, radiation, and targeted therapy might be used too. These are picked based on the tumor’s and patient’s characteristics. They play a big role in fighting MFH.
Chemotherapy uses strong medicines to kill cancer cells all over the body. These medicines can be taken by mouth or through a vein. They can slow down the tumor’s growth, reduce its size, and better the outlook for the patient.
Radiation therapy uses strong energy to kill cancer cells. It’s often used after surgery to get rid of any leftover cells. Sometimes, doctors use it before surgery to make the tumor smaller and easier to remove.
Targeted therapy focuses on specific genes or proteins in the cancer cells. It aims to stop the cancer cells from growing and surviving. This more personalized approach can improve treatment results.
How well a patient does in treatment depends on many things. The tumor’s size and location, its cell appearance, and the patient’s details like age, sex, and health, all matter. Any past treatments and genetic conditions are important too. Doctors keep an eye on these to adjust the treatment as needed.
The outlook for MFH can vary from person to person. Generally, about 60% of MFH patients live up to 5 years after treatment, and 48% can live up to 10 years. Yet, the cancer can return in 13-42% of cases, making regular check-ups vital. This way, any signs of the cancer returning can be caught early and treated effectively.
Conclusion
Malignant fibrous histiocytoma (MFH), known as undifferentiated pleomorphic sarcoma (UPS), is rare and aggressive. It affects soft tissues or bones. This cancer tends to come back after treatment and can spread to other parts of the body. So, treating it is tough.
The causes of MFH/UPS are not clear, but age and past radiation may play a part. Doctors need to do many tests like exams and biopsies to be sure of the diagnosis.
There are several ways to treat MFH/UPS, including surgery, chemotherapy, and radiotherapy. The best treatment depends on the tumor’s size and where it is. Scientists are also looking into stem cell therapy as a new treatment.
Each person’s outlook with MFH/UPS is different. It’s important to keep seeing the doctor to check for any return of the cancer. With more research, we hope to find better ways to treat and care for those with MFH/UPS.
