RESUMO
BACKGROUND: Intracranial solitary fibrous tumour (iSFT) is an exceptional mesenchymal tumour with high recurrence rates. We aimed to analyse the clinical outcomes of newly diagnosed and recurrent iSFTs. METHODS: We carried out a French retrospective multicentre (n = 16) study of histologically proven iSFT cases. Univariate and multivariate Cox models were used to estimate the prognosis value of the age, location, size, WHO grade, and surgical extent on overall survival (OS), progression-free survival (PFS), and local recurrence-free survival (LRFS). RESULTS: Eighty-eight patients were included with a median age of 54.5 years. New iSFT cases were treated with gross tumour resection (GTR) (n = 75) or subtotal resection (STR) (n = 9) and postoperative radiotherapy (PORT) (n = 32, 57%). The median follow-up time was 7 years. The median OS, PFS, and LRFS were 13 years, 7 years, and 7 years, respectively. Forty-two patients experienced recurrence. Extracranial metastasis occurred in 16 patients. Median OS and PFS after the first recurrence were 6 years and 15.4 months, respectively. A higher histological grade was a prognosis factor for PFS (p = 0.04) and LRFS (p = 0.03). GTR influenced LRFS (p = 0.03). CONCLUSION: GTR provided benefits as a first treatment for iSFTs. However, approximately 40% of patients experienced relapse, which remains a challenging state.
RESUMO
INTRODUCTION: Admission of metastatic cancer patients to the intensive care unit (ICU) poses medical and ethical challenges in the absence of reliable prognostic tools to guide decision-making. MATERIAL AND METHODS: We retrospectively analyzed the medical charts of 129 consecutive patients with metastatic solid tumors admitted to the ICU between January and September 2014 and identified prognostic factors (PFs) using Cox models. RESULTS: The mean patient age at ICU admission was 58.9 years (range, 25-81 years; males, 51%). Performance status (PS) was 0-1 and 2-3 in 61% and 39% of the patients, respectively. The most prevalent cancers were lung cancer (20%), sarcoma (17%), and breast cancer (16%). ICU admission was attributable to the cancer itself (53%), cancer treatment toxicity (43%), and comorbidities (37%). The median overall survival (OS) after ICU admission was 2.6 months; 15% of the patients died during the ICU stay. Poor PFs for OS were PS >1 before ICU admission (p = 0.007) and ICU admission for the cancer itself (p < 10-3). After ICU discharge, 58% and 42% of the patients received systemic treatment within 12 months and showed good PS recovery, respectively. Multiple organ failure and a multidisciplinary decision to limit therapeutic efforts were poor PFs for reinitiation of systemic treatment (p = 0.2 and 0.006, respectively), and the latter was also a poor PF for PS recovery (p = 0.004). DISCUSSION: In the ICU, the OS of adult patients with solid tumors was similar to that of the noncancer population. For ICU admissions related to the cancer itself, the prognosis is poor.
