ABSTRACT
BACKGROUND:
Hyperthermic isolated limb perfusion (HILP) is a locoregional treatment aimed at avoiding amputation in patients with advanced extremity soft tissue sarcomas (STS). Over the last 25 years, HILP procedure has been implemented to maximise its therapeutic ratio.METHODS:
A retrospective analysis including 117 patients who underwent HILP from 1989 to 2013 was performed. Three different drug schedules were applied 1) doxorubicin (n = 47), 2) high dose (3-4 mg) tumour necrosis factor-alpha (TNF-α) plus doxorubicin (n = 30), 3) low dose (1 mg) TNF-α plus melphalan (L-PAM) (n = 40). Tumour response was evaluated by MRI or CT and surgical specimens. Toxicity and local progression-free survival (LPFS) were also evaluated.RESULTS:
In total 92 (78.6%) patients had primary, 25 (21.4%) had recurrent and 17 (14.5%) had metastatic disease. The subjects in the three groups were homogeneous for clinical-pathological features. Pathological response was complete in 55 patients (47%), partial in 35 (29.9%), regardless of drug schedule (p = 0.501) and tumour presentation (p = 0.094). Wieberdink III-V toxicity was registered in 19.1%, 20% and 2.5% of patients, respectively (p < 0.051). Twenty-eight patients (23.9%) received adjuvant radiotherapy with no relevant toxicity. Five-year LPFS was 81.6% and 74.2% in patients with primary or recurrent disease, respectively (p = 0.652). After a median follow-up of 36.5 months, the limb sparing rate was 77.8%.CONCLUSIONS:
HILP performed with different drugs was equally active, either in primary, recurrent or metastatic STS, providing effective limb sparing and durable local control. Low dose TNF-α plus L-PAM had the most favourable toxicity profile. Adjuvant radiotherapy was not associated with relevant toxicity.Key words
