First Nationwide Molecular Screening Program in Spain for Patients With Advanced Breast Cancer: Results From the AGATA SOLTI-1301 Study
2021
Anàlisi de seqüències d'ADN; Subtipus PAM50; Genètica molecular Análisis de secuencias de ADN; Subtipo PAM50; Genética molecular DNA sequence analyses; PAM50 subtype; Molecular genetic Background: The SOLTI-1301 AGATA study aimed to assess the feasibility of a multi-institutional molecular screening program to better characterize the genomic landscape of advanced breast cancer (ABC) and to facilitate patient access to matched-targeted therapies in Spain. Methods: DNA sequencing of 74 cancer-related genes was performed using FFPE tumor samples in three different laboratories with three different gene panels. A multidisciplinary advisory board prospectively recommended potential targeted trea…
Treatment for patients with relapsed/refractory mantle cell lymphoma: European-based recommendations
2017
International audience; Patients with mantle cell lymphoma (MCL) usually respond to initial combination chemotherapy, but the disease inevitably relapses and often follows an aggressive course. Here, clinical study results published since 2008 for patients with relapsed/refractory MCL were reviewed to compare available evidence for treatment guidance. Most trials identified were non-randomized, phase II studies performed at a limited number of sites, and many evaluated MCL as one of multiple non-Hodgkin lymphoma subtypes. Additional randomized, comparative trials are needed. Treatment selection generally depends on patient need, age and fitness, time of relapse, and line of therapy. Combina…
Distinct HR expression patterns significantly affect the clinical behavior of metastatic HER2+ breast cancer and degree of benefit from novel anti-HE…
2020
We analyzed data from 738 HER2‐positive metastatic breast cancer (mbc) patients treated with pertuzumab‐based regimens and/or T‐DM1 at 45 Italian centers. Outcomes were explored in relation to tumor subtype assessed by immunohistochemistry (IHC). The median progression‐free survival at first‐line (mPFS1) was 12 months. Pertuzumab as first‐line conferred longer mPFS1 compared to other first‐line treatments (16 vs. 9 months, p = 0.0001), regardless of IHC subtype. Median PFS in second‐line (mPFS2) was 7 months, with no difference by IHC subtype, but it was more favorable with T‐DM1 compared to other agents (7 vs. 6 months, p = 0.03). There was no PFS2 gain in patients with tumors expressing b…
A prospective randomised, open-labeled, trial comparing sirolimus-containing versus mTOR-inhibitor-free immunosuppression in patients undergoing live…
2010
Abstract Background The potential anti-cancer effects of mammalian target of rapamycin (mTOR) inhibitors are being intensively studied. To date, however, few randomised clinical trials (RCT) have been performed to demonstrate anti-neoplastic effects in the pure oncology setting, and at present, no oncology endpoint-directed RCT has been reported in the high-malignancy risk population of immunosuppressed transplant recipients. Interestingly, since mTOR inhibitors have both immunosuppressive and anti-cancer effects, they have the potential to simultaneously protect against immunologic graft loss and tumour development. Therefore, we designed a prospective RCT to determine if the mTOR inhibito…
Esophagogastric cancer: integration of targeted therapies into systemic chemotherapy.
2011
Although combination chemotherapy has been shown to be more effective than single agents in advanced esophagogastric cancer, the better response rates have not fulfilled their promise as overall survival times from best combination still range between 8 to 11 months. So far, the development of targeted therapies stays somewhat behind their integration into treatment concepts compared to other gastrointestinal diseases. Thus, the review summarizes the recent advances in the development of targeted therapies in advanced esophagogastric cancer. The majority of agents tested were angiogenesis inhibitors or agents targeting the epidermal growth factor receptors EGFR1 and HER2. For trastuzumab an…
Clinical results of EGFR-targeted therapies in advanced colorectal cancer
2008
Abstract This paper is an updated review of the pre-clinical rationale and clinical results of new EGFR-targeted agents – cetuximab and panitumumab – employed in the management of advanced/ metastatic colorectal cancer. The addition of either biologic agent or last generation standard chemotherapy regimens – FOLFIRI and FOLFOX – has yielded better results as compared to those reported for chemotherapy alone. These results have been obtained without a significant increase in severe toxicity with the exception of skin side-effects.
Targeting breast cancer initiating cells: advances in breast cancer research and therapy
2014
Over the past 10 years there have been significant advances in our understanding of breast cancer and the important roles that breast cancer initiating cells (CICs) play in the development and resistance of breast cancer. Breast CICs endowed with self-renewing and tumor-initiating capacities are believed to be responsible for the relapses which often occur after various breast cancer therapies. In this review, we will summarize some of the key developments in breast CICs which will include discussion of some of the key genes implicated: estrogen receptor (. ER), HER2, BRCA1, TP53, PIK3CA, RB, P16INK1 and various miRs as well some drugs which are showing promise in targeting CICs. In additio…
Encorafenib plus Binimetinib in patients with locally advanced, unresectable or metastatic BRAFV600-mutant melanoma: First data of the multicenter, m…
2021
9555 Background: For the treatment of advanced BRAFV600-mutated melanoma, targeted therapy (BRAF/MEK-inhibition) is a standard of care. Encorafenib + binimetinib (EB) were approved in the EU in Sep 2018 and in Switzerland in Nov 2019, based on positive results from COLUMBUS (NCT01909453), with a median progression-free survival (PFS) of 14.9 mo (4-year PFS: 26%) and overall survival (OS) of 33.6 mo (4-year OS: 39%). As data from controlled trials are based on selected populations, BERINGMELANOMA investigates the use of EB under real-world conditions in a broader population. Methods: BERINGMELANOMA is an ongoing, multi-national, multi-center, prospective, longitudinal, non-interventional st…
In the literature: October 2019
2019
Gastrointestinal cancers are a subset of molecularly heterogeneous diseases. In the era of personalised medicine, major efforts are being made towards stratifying patients according to molecular profiling. However, although most treatments are currently based on targeted therapy in relation to specific genomic alterations, acquired resistance emerges during anticancer therapies and subsequently treatment failure occurs. Intratumour heterogeneity plays a significant role in the acquisition of resistance by clonal evolution of tumour cell populations under therapeutic pressure. Despite a single tumour biopsy represents the standard for cancer research and drives our therapeutic decisions, lim…
A systematic review and meta-analysis of randomized trials on the role of targeted therapy in the management of advanced gastric cancer: Evidence doe…
2015
It is still uncertain if targeted therapy-based regimens in advanced gastric cancer actually produce survival benefit. To shed light on this important question, we performed a systematic review and meta-analyses on each relevant targeted-pathway. By searching literature databases and proceedings of major cancer meetings in the time-frame 2005–2014, 22 randomized clinical trials exploring targeted therapy for a total of 7022 advanced gastric cancer patients were selected and included in the final analysis. Benefit was demonstrated for antiangiogenic agents in terms of overall survival (HR 0.759; 95%CI 0.655–0.880; p < 0.001). Conversely no benefit was found for EGFR pathway (HR 1.077; 95%…
