Results
Between 1st January 2017 and 30th June 2017,
70 patients underwent a total of 94 courses of palliative radiotherapy treatment.
The mean age was 69.3,
with a range from 46 to 97. The male to female ratio was 3:2,
with 42 males and 28 females undergoing treatment.
There were 14 different primary tumour types treated.
Lung (27.1%) and prostate (25.7%) cancer were the most common tumour types (Figure 1).
59.6% of patients were treated with a single 8Gy fraction,
31.9% with 20Gy in 5 fractions and the remaining were all delivered with multi-fraction treatment (Figure 2).
The majority of treatments (89.4%) were planned with simple 2D radiotherapy techniques however 6.4% were CT planned and treated with 3D-CRT or VMAT (Figure 3).
12 patients (17.1%) died within 30 days of completing their treatment.
The majority (9) died following a single 8Gy fraction; 2 died following 20Gy in 5 fractions; and the remaining patient died as a direct result of the radiotherapy.
This patient received 8Gy in 2 fractions,
planned in 2D with wedge, to the right ileum.
Unfortunately,
the radiotherapy perforated the small bowel - a known complication which was consented for - and the patient died 9 days later.
