Abstract
Introduction
Rhabdomyosarcoma (RMS) is the most common soft tissue sarcoma in children. This paper aimed to assess the stage, site and treatment outcome among RMS patients.
Materials and Methods
A retrospective chart review was completed from January 2011 to December 2017 of patients that presented to the Department of Paediatric Oncology, Shaukat Khanum Memorial Cancer Hospital, Lahore, Pakistan, for the management of RMS. Data collection included clinical characteristics, staging, grouping, risk stratification, treatment plan, radiotherapy doses and treatment outcome.
Results
Among 24 subjects, there were a total of 13 (54.2%) males and 11 (45.8%) females. The median age at the time of diagnosis was 2.5 years (range: 0.75–17 years). The majority of the subjects (91.7%) were <10 years of age. The median follow-up time was 0.6 years. According to the Children’s Oncology Group Classification, 4 (16.7%) subjects were classified as low risk, 14 (58.3%) subjects were rated as intermediate risk and 6 (0.25%) subjects were stratified as high risk. The most common primary tumour site was genitourinary (62.5%) and abdomen/retroperitoneal (20.8%) regions. At the time of analysis, nine (37.5%) subjects had died because of the disease, 12 (50%) were alive with no evidence of disease and one subject had a recurrence of disease and was alive. One subject had abandoned the therapy and another was lost to follow-up.
Conclusion
Patients with RMS presented at the late stages of the disease and it most frequently affected genitourinary and abdomen or retroperitoneal areas. Overall, RMS was found to have a poor outcome to therapy.
