First line palliative chemotherapy in elderly patients with advanced soft tissue sarcoma.

BACKGROUND

The efficacy and toxicity of first line palliative chemotherapy for soft tissue sarcomas (STS) in the elderly is poorly described.

METHODS

Patients over the age of 65 years receiving first line chemotherapy for advanced non-GIST STS January 1998 - January 2012 at the Royal Marsden Hospital were identified. Data regarding survival and predictive factors were collected retrospectively.

RESULTS

120 patients (52 females) with a median age of 72 (range 65-83) were treated. The most common histological subtypes were undifferentiated sarcoma (30%), leiomyosarcoma (27%), angiosarcoma (14%). 42% of patients had high grade tumours. 70% of patients had metastatic disease at presentation; lung metastasis being the most common disease site (72%). 80% received single agent chemotherapy, mostly with doxorubicin (60%). The median number of cycles was 2 (IQR 3). A partial response was reported in 20% of patients with disease stabilisation in a further 20%. 38% of patients were hospitalised for chemotherapy related toxicity. The median overall survival (OS) was 6.5 months (95% CI 4.7-8.3). Anaemia, lymphopenia, hypoalbuminemia, sarcoma subtype and co-morbidities were predictive for overall survival.

CONCLUSION

The overall survival for elderly patients with STS is poor but several predictive factors have been identified. Hospital admissions for chemotherapy related toxicity are common.
