Desmoplastic small round cell tumors (DSRCT)

Overview

Desmoplastic small round cell tumors (DSRCT) are exceptionally rare cancers that typically originate in the abdomen. Although they primarily affect the peritoneum (the tissue lining the abdominal cavity), they can also occur in other areas of the body. Let’s delve into the specifics:

1. Definition:

   • DSRCT is a type of soft tissue sarcoma characterized by small, round cancer cells surrounded by scar-like tissue.
   • These tumors often present as multiple nodules within the peritoneum.

2. Incidence and Demographics:

   • DSRCT predominantly affects young males and boys.
   • The exact incidence is uncertain due to its rarity.

Types of Desmoplastic small round cell tumors (DSRCT)

DSRCT is primarily classified as a soft tissue sarcoma. While it typically arises in the abdomen, it can occasionally occur elsewhere. Let’s explore the different types:

1. Abdominal DSRCT:

   • The most common form, originating within the peritoneum.
   • Presents with abdominal pain, swelling, and discomfort.

2. Extra-Abdominal DSRCT:

   • Rare cases occur outside the abdomen (e.g., chest, pelvis, extremities).
   • Diagnosis requires careful evaluation and differentiation from other tumors.

Causes of Desmoplastic small round cell tumors (DSRCT)

The precise cause of DSRCT remains elusive, but several factors are associated with its development:

1. Genetic Abnormalities:

   • Chromosomal translocation involving chromosomes 11 and 22 leads to the fusion of the EWSR1 and WT1 genes.
   • This fusion results in uncontrolled cell proliferation and tumor formation.

2. Not Inherited:

   • DSRCT is not an inherited condition; it arises sporadically during an individual’s lifetime.

Risk Factors of Desmoplastic small round cell tumors (DSRCT)

DSRCT lacks specific risk factors. However, consider the following:

Age and Gender:

• • Primarily affects children, adolescents, and young adults.
  • More common in males.

Preventions of Desmoplastic small round cell tumors (DSRCT)

1. Awareness and Education:

   • Educate yourself and others about DSRCT, its risk factors, and symptoms.
   • Early awareness can lead to timely diagnosis and intervention.

2. No Specific Prevention Measures:

   • Unfortunately, there are no specific preventive measures for DSRCT due to its rarity and unclear etiology.
   • Focus on overall health and well-being to support your immune system.

Diagnosis of Desmoplastic small round cell tumors (DSRCT)

Prompt diagnosis ensures timely management:

1. Imaging:

   • Ultrasound, CT scan, MRI, and PET scans reveal tumor size and location.

2. Biopsy:

   • Essential for confirming DSRCT.
   • Microscopic examination identifies characteristic EWS-WT1 fusion protein.

Treatment for Desmoplastic small round cell tumors (DSRCT)

A multidisciplinary approach is essential:

1. Surgery:

   • Aim: Complete tumor removal (debulking).
   • Often challenging due to widespread disease.

2. Chemotherapy:

   • Used alongside surgery for larger tumors or metastatic disease.
   • Intensive regimens improve outcomes.

3. Hyperthermic Intraperitoneal Chemotherapy (HIPEC):

   • Warmed chemotherapy delivered directly into the abdominal cavity during surgery.

4. Radiation Therapy:

   • External or internal radiation targets cancer cells.

When to seek medical attention ?

1. Persistent Symptoms:

   • If you experience persistent abdominal pain, swelling, or discomfort, seek medical attention promptly.
   • Other symptoms, such as changes in bowel habits, nausea, or vomiting, should also prompt evaluation.

2. Unexplained Weight Loss:

   • Sudden, unexplained weight loss may indicate an underlying health issue, including DSRCT.
   • Consult a doctor if you notice significant weight changes without an apparent cause.

3. Family History:

   • If you have a family history of DSRCT or other soft tissue sarcomas, discuss it with your healthcare provider.
   • Regular check-ups and screenings may be recommended.

4. Abdominal Distension:

   • A swollen or distended abdomen that persists should be evaluated.
   • It could be a sign of DSRCT or other abdominal conditions.
