Summary
Ocular Rhabdomyosarcoma (ORMS) in Karachi shows a dismal survival rate, with no survivors after three years. Early diagnosis through public health education and improved ophthalmologic screening is crucial for better outcomes in this rare childhood cancer.
Area of Science:
- Ophthalmology
- Pediatric Oncology
- Epidemiology
Background:
- Ocular Rhabdomyosarcoma (ORMS) is a rare and aggressive malignancy affecting the eye socket.
- Epidemiological data on ORMS in developing regions like Karachi are scarce.
Purpose of the Study:
- To investigate the epidemiology and survival patterns of ocular Rhabdomyosarcoma in Karachi.
- To highlight the need for early diagnosis and improved healthcare strategies for ORMS.
Main Methods:
- Retrospective analysis of incident ORMS cases registered at the Karachi Cancer Registry (KCR) from 1998 to 2002.
- Data classification using ICD-O2, computerized with Canreg-3, and statistical analysis using SPSS 10.0.
Main Results:
- Ten cases of ORMS were identified, primarily originating in the orbit.
- The crude annual incidence rate was 0.13/100,000, with a standardized rate of 0.3/100,000.
- One-year survival was 70%, dropping to 20% at two years, with no three-year survivors, indicating a dismal prognosis.
Conclusions:
- ORMS in Karachi presents with poor survival, possibly due to late diagnosis or unique genetic factors.
- Enhanced public and healthcare provider education is vital for early ORMS detection.
- Strengthening ophthalmologic screening capacity and conducting cytogenetic studies are recommended for better management and understanding of ORMS.

Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.

01:20The Retinoblastoma Gene
Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...
