PML as a potential predictive factor of oxaliplatin/fluoropyrimidine-based first line chemotherapy efficacy in colorectal cancer patients
2012
PML regulates a wide range of pathways involved in tumorigenesis, such as apoptosis, which is also one of the main mechanisms through which oxaliplatin and fluoropyrimidine exert their antineoplastic activity. The present study aims to investigate PML expression as a predictive factor of oxaliplatin/fluoropyrimidine therapy efficacy. Seventy-four metastatic colorectal cancer patients who received oxaliplatin/floropyrimidine-based first line therapy have been included in this retrospective study. PML expression was assessed by immunohistochemistry. PML down-regulation was detected in 39 (52.7%) patients (14 complete and 25 partial PML loss). RR was significantly lower (25.6%) in patients wit…
PML expression in soft tissue sarcoma: Prognostic and predictive value in alkylating agents/antracycline-based first line therapy
2012
Soft tissue sarcomas are aggressive tumors representing <1% of all adult neoplasms. Aim of our study was to evaluate promyelocytic leukemia gene expression value as prognostic factor and as a factor predicting response to alkylating agents/antracycline-based first line therapy. One hundred eleven patients affected by locally advanced and metastatic soft tissue sarcoma were selected. PML expression was evaluated by immunohistochemical analysis in pathological samples and in the corresponding normal tissue from each case. PML immunohistochemical results were correlated with prognosis and with radiological response to alkylating agents/antracycline-based first line therapy. PML expression was …
Advanced epithelioid haemangioendotelioma: Fever, pain, and pleural effusion predict a worse outcome.
2019
e22540 Background: Epithelioid hemangioendothelioma (EHE) is an exceedingly rare soft tissue sarcoma subtype. EHE often presents as a multifocal/ multivisceral disease and its clinical behavior is highly unpredictable from indolent to very aggressive forms. A common choice in advanced patients is a close, active surveillance (AS), considering a treatment only in case of disease progression. Our retrospective study aimed to identify clinical features associated with a more aggressive behavior. Methods: Patients affected by advanced EHE treated in 6 centers of the Italian Rare Cancer Network were retrospectively reviewed. Diagnosis was confirmed by a sarcoma expert pathologist and molecular …
Cetuximab rechallenge in metastatic colorectal cancer patients: how to come away from acquired resistance?
2012
Background: Scientific data provide the evidence that secondary K-RAS mutations do not occur during anti-epidermal growth factor receptor therapy in colorectal cancer patients. This multicenter phase II prospective study aims to investigate the activity of a retreatment with a cetuximab-based therapy. Patients and methods: We enrolled 39 irinotecan-refractory patients who had a clinical benefit after a line of cetuximab- plus irinotecan-based therapy and then a progression of disease for which underwent a new line chemotherapy and finally, after a clear new progression of disease, were retreated with the same cetuximab- plus irinotecan-based therapy. Results: Median number of therapeutic li…
Bone metastases in soft tissue sarcoma: a survey of natural history, prognostic value and treatment options
2013
Abstract Background We surveyed the natural history of bone metastases in patients affected by soft tissue sarcoma (STS). Methods This multicenter retrospective observational study included 135 patients. Histological subtype, characteristics of bone metastases, treatment, skeletal related events (SREs) and disease outcome were recorded. Results The most represented histological subtypes were leiomyosarcoma (27%) angiosarcoma (13%) and undifferentiated sarcoma (8%). Axial skeleton was the most common site for bone involvement (70%). In 27% of cases, bone metastases were present at the time of diagnosis. Fifty-four (40%) patients developed SREs and the median time to first SRE was 4 months (r…
Early Skin Toxicity as a Predictive Factor for Tumor Control in Hepatocellular Carcinoma Patients Treated with Sorafenib.
2010
Abstract Introduction. Sorafenib is an oral multikinase inhibitor that targets Raf kinase and receptor tyrosine kinases and has led to a longer median overall survival (OS) time and time to progression (TTP) in patients with advanced hepatocellular carcinoma (HCC). This study was conducted to assess the link between the antitumor efficacy of sorafenib and its early cutaneous side effects in advanced HCC patients. Materials and Methods. All patients received 800 mg daily of sorafenib until progression or unacceptable toxicities. We retrospectively analyzed the incidence of rash and hand–foot skin reactions (HFSR) during the first month of treatment, comparing tumor control (partial response …
Bone metastases in soft tissue sarcoma patients: A survey of natural, prognostic value, and treatment.
2012
10063 Background: Given the limited data currently available, we surveyed the natural history of bone metastases in patients affected by soft tissue sarcoma (STS). Methods: This retrospective, multicenter, observational study evaluated data from 135 patients with STS metastatic to the bone who presented between 2001 and 2011. For all patients, we recorded the primary tumor histological subtype, bone metastases characteristics (onset, site), type of treatment received (surgery, radiotherapy, zoledronic acid), type and frequency of skeletal related events (SRE) and disease outcome. Results: The most represented histological subtypes among the enrolled patients were leiomyosarcoma (27%), angi…
Deregulation of dicer and mir-155 expression in liposarcoma
2015
Liposarcoma (LPS) is the most common soft tissue sarcoma. It has been demonstrated that mir-155 was the most overexpressed miRNA in well-differentiated LPS(WDLPS)/dedifferentiated LPS (DDLPS). The aim of this study is to evaluate the involvement of Dicer, Drosha and mir-155 in development of LPS and their possible role in stratification of different histological subtypes. Dicer, Drosha and mir-155 mRNA levels were analyzed in formalin-fixed paraffin-embedded specimens from patients diagnosed with 62 LPS and compared with samples of adipose tissues of healthy donors. The experimental data were obtained using qRT-PCR comparing Dicer, Drosha and mir-155 expression levels in tumor samples versu…
Trabectedin-Related Liver Toxicity in Soft Tissue Sarcoma Patients: Always a Good Reason to Discontinue the Treatment?
2014
ABSTRACT Aim: A transient increase in liver enzymes is a well described side effect developed by almost 40% of soft tissue sarcoma (STS) patients treated with trabectedin, often leading to treatment delays or discontinuation. We retrospectively analysed the correlation between trabectedin-related liver toxicity and treatment outcome. Methods: Data from a total of 113 patients receiving trabectedin administered at the dose of 1.5 mg/m2 iv 24 hours in 3 reference centers were evaluated. This exploratory analysis was performed to assess the impact of liver toxicity (grade 3-4 AST and ALT increases) on the trabectedin efficacy and outcome in STS patients. All the patients included had metastati…

Lack of Correlation between Liver Tests Abnormalities and Trabectedin Efficacy in the Treatment of Soft Tissue Sarcoma: A Retrospective Study
2015
AbstractElevation in liver transaminases is common in patients treated with the marine antitumor agent trabectedin. However, the impact of trabectedin-related transaminase elevations on treatment outcomes is unclear. This retrospective study investigated the correlation between liver tests abnormalities and treatment outcomes in patients with unresectable advanced or metastatic soft tissue sarcomas (STS) treated with trabectedin 1.5 mg/m2 once every 3 weeks at three reference centers in Italy. The effect of grade 3/4 elevations in alanine aminotransferase (ALT) or aspartate aminotransferase (AST) during the first two cycles and at any time during trabectedin treatment on progression-free su…
Weekly cisplatin with or without imatinib in advanced chordoma: A retrospective case-series analysis from the Italian Rare Cancers Network
2021
Background: To report on a retrospective case-series analysis of weekly cisplatin (wCDDP) as a single agent or combined with imatinib (wCDDP/I) in patients with advanced chordoma treated within the Italian Rare Cancer Network. Methods: Adult patients with a diagnosis of advanced, brachyury-positive chordoma, treated from April 2007 to October 2020 with wCDDP or wCDDP/I were retrospectively identified. Imatinib was withheld at the same time as wCDDP. Response according to Response Evaluation Criteria in Solid Tumors, overall survival (OS), and progression-free survival (PFS) were analyzed. Results: Thirty-three consecutive patients were identified (wCDDP as front-line n = 8 [24.2%]; wCDDP as…
Imatinib dose escalation versus sunitinib as a second line treatment in KIT exon 11 mutated GIST: a retrospective analysis
2015
We retrospectively reviewed data from 123 patients (KIT exon 11 mutated) who received sunitinib or dose-escalated imatinib as second line. All patients progressed on imatinib (400 mg/die) and received a second line treatment with imatinib (800 mg/die) or sunitinib (50 mg/die 4 weeks on/2 off or 37.5 mg/day). Deletion versus other KIT 11 mutation was recorded, correlated with clinical benefits. 64% received imatinib, 36% sunitinib. KIT exon 11 mutation was available in 94 patients. With a median follow-up of 61 months, median time to progression (TTP) in patients receiving sunitinib and imatinib was 10 (95% CI 9.7–10.9) and 5 months (95% CI 3.6–6.7) respectively (P = 0.012). No difference wa…
