Radiation therapy in skeletal metastases

Area of Science:

• Oncology
• Radiotherapy
• Palliative Care

Background:

• Skeletal metastases are a common complication of advanced cancer, leading to significant morbidity, particularly pain.
• Palliative radiotherapy (RT) is a cornerstone in managing symptoms associated with bone metastases.
• Optimizing RT delivery is crucial, especially in settings with limited resources and patient access challenges.

Purpose of the Study:

• To evaluate the effectiveness of palliative radiotherapy in managing skeletal metastases.
• To assess patient demographics, common primary tumor types, and metastatic sites.
• To determine the optimal fractionation schedule for palliative RT in a resource-constrained environment.

Main Methods:

• Retrospective review of 132 patient case files who received palliative RT for skeletal metastases between June 1993 and September 1995.
• Analysis of patient age, primary tumor origin, metastatic sites, presenting symptoms, and RT doses/fractionation.
• Assessment of symptomatic response rates post-treatment.

Main Results:

• The majority of patients (75/132) were aged 41-60 years.
• Common sites of metastases included vertebrae (86) and pelvic bones (40), with primary cancers like multiple myeloma (30), breast (25), and prostate (20).
• Ninety-four patients (out of 120 with follow-up) achieved >50% symptomatic response, with single fraction RT showing comparable efficacy to multiple fractions.

Conclusions:

• Short-course palliative radiotherapy regimens are effective and suitable for managing skeletal metastases.
• This approach is particularly advantageous in resource-limited settings and for patients facing travel difficulties.
• Palliative RT provides significant symptomatic relief for patients with painful bone metastases.
