ABSTRACT

BACKGROUND: This multicentric, retrospective study conducted within the Italian Rare Cancer Network describes clinical features and explores their possible prognostic relevance in patients with advanced epithelioid haemangioendothelioma (EHE) started on surveillance. PATIENTS AND METHODS: We collected data on adult patients with molecularly confirmed, advanced EHE consecutively referred at five sarcoma reference centres between January 2010 and June 2018, with no evidence of progressive disease (PD) and started on surveillance. Overall survival (OS) and progression-free survival (PFS) univariable and multivariable Cox analyses were performed. In the latter, due to the low number of cases and events, penalized likelihood was applied, and variable selection was performed using a random forest model. RESULTS: Sixty-seven patients were included. With a median follow-up of 50.2 months, 51 (76%) patients developed PD and 16 (24%) remained stable. PD at treatment start did not meet RECIST version 1.1 in 15/51 (29%) patients. The 3-year PFS and OS were 25.4% and 71.1%, respectively, in the whole population. Tumour-related pain (TRP) was the most common baseline symptom (32.8%), followed by temperature (20.9%), fatigue (17.9%), and weight loss (16.4%). Baseline TRP (P = 0.0002), development of TRP during follow-up (P = 0.005), baseline temperature (P = 0.002), and development of fatigue during follow-up (P = 0.007) were associated with a significantly worst PFS. An association between baseline TRP (P < 0.0001), development of TRP during follow-up (P = 0.0009), evidence of baseline serosal effusion (P = 0.121), and OS was recorded. CONCLUSION: Because of the poor outcome observed in EHE patients presenting with serosal effusion, TRP, temperature, or serosal effusion, upfront treatment in this subgroup could be considered.

ABSTRACT

BACKGROUND: To explore the activity of axitinib in advanced solitary fibrous tumour (SFT). PATIENTS AND METHODS: In this investigator-driven phase II study on axitinib in advanced and progressive SFT, patients received axitinib, 5 mg bis in day (BID), until progression or limiting toxicity. Pathologic diagnosis was centrally reviewed, distinguishing malignant SFT (M-SFT) and high-grade/dedifferentiated SFT (HG/D-SFT) subtypes. The primary end-point was the overall response rate (ORR) by Choi criteria (Choi). Secondary end-points were response by Response Evaluation Criteria in Solid Tumours (RECIST), progression-free survival (PFS) and overall survival (OS). RESULTS: From April 2015 and October 2017, 17 eligible patients entered the study (metastatic: 17; SFT subtype: 13 M-SFT, 4 HG/D-SFT; prior treatment: 9 antiangiogenics, 5 cytotoxics). All patients were evaluable for response. The best Choi response was seven partial response (PR) (ORR, 41.2%), six stable disease (SD) and four progressions. Choi-ORR was 54% (7/13) when only M-SFTs were considered. Four of seven responsive patients were pretreated with pazopanib. No responses were detected in HG/D-SFT. Best RECIST response was one PR (5.9%), 14 SD and two progressions. Toxicity was as expected. Median Choi-PFS was 5.1 (interquartile range [IQR]: 2.5-14.8) months. Median Choi-PFS was 14.8 (IQR: 5.1-18.0) and 2.8 (IQR: 2.0-5.9) months for patients responsive and non-responsive by Choi, respectively (p = 0.0416). At a 14.4-month median follow-up, median OS was 25.3 months. CONCLUSION: This study showed that axitinib is active in progressive advanced SFT. One-half of patients carrying the malignant variant of the disease responded, with a >12-month median progression arrest. Responses were better detected with Choi and seen even in patients resistant to other antiangiogenics. Tolerability was good.
