Combining germline, tissue and liquid biopsy analysis by comprehensive genomic profiling to improve the yield of actionable variants in a real-world cancer cohort.

Background: Comprehensive next-generation sequencing is widely used for precision oncology and precision prevention approaches. We aimed to determine the yield of actionable gene variants, the capacity to uncover hereditary predisposition and liquid biopsy appropriateness instead of, or in addition to, tumor tissue analysis, in a real-world cohort of cancer patients, who may benefit the most from comprehensive genomic profiling.

Methods: Seventy-eight matched germline/tumor tissue/liquid biopsy DNA and RNA samples were profiled using the Hereditary Cancer Panel (germline) and the TruSight Oncology 500 panel (tumor tissue/cfDNA) from 23 patients consecutively enrolled at our center according to at least one of the following criteria: no available therapeutic options; long responding patients potentially fit for other therapies; rare tumor; suspected hereditary cancer; primary cancer with high metastatic potential; tumor of unknown primary origin.

Clinical recommendations for treatment of localized angiosarcoma: A consensus paper by the Italian Sarcoma Group.

Angiosarcoma (AS) represents a rare and aggressive vascular sarcoma, posing distinct challenges in clinical management compared to other sarcomas. While the current European Society of Medical Oncology (ESMO) clinical practice guidelines for sarcoma treatment are applicable to AS, its unique aggressiveness and diverse tumor presentations necessitate dedicated and detailed clinical recommendations, which are currently lacking. Notably, considerations regarding surgical extent, radiation therapy (RT), and neoadjuvant/adjuvant chemotherapy vary significantly in localized disease, depending on each different site of onset.

Guideline-Based Follow-Up Outcomes in Patients With Gastrointestinal Stromal Tumor With Low Risk of Recurrence: A Report From the Italian Sarcoma Group.

Importance: Gastrointestinal stromal tumor (GIST) follow-up is recommended by international guidelines, but data on the role of follow-up in patients with low relapse risk are missing. For these patients, the potential benefit of anticipating recurrence detection should be weighed against psychological burden and radiologic examination loads in terms of costs and radiation exposure.

Objective: To evaluate the outcomes of guideline-based follow-up in low-risk GIST.

Molecular Tailored Therapeutic Options for Advanced Gastrointestinal Stromal Tumors (GISTs): Current Practice and Future Perspectives.

Gastrointestinal stromal tumors (GISTs) are one of the most common mesenchymal tumors characterized by different molecular alterations that lead to specific clinical presentations and behaviors. In the last twenty years, thanks to the discovery of these mutations, several new treatment options have emerged. This review provides an extensive overview of GISTs' molecular pathways and their respective tailored therapeutic strategies.

Reliability of patient-reported toxicities during adjuvant chemotherapy.

Background: Patient-reported outcomes (PROs) are validated tools to assess the impact of efficacy and toxicities of cancer treatments on patients' health status. Because of the demonstrated little reliability of humans in reporting memories of painful experiences, this work explores the reliability of cancer patients in reporting chemotherapy-related toxicities.

Aim: This study aims to evaluate the concordance between toxicities experienced by the patients during chemotherapy and toxicities reported to the doctor at the end of the cycles.

Counting mitoses in gastrointestinal stromal tumours (GISTs): variable practices in the real-world setting and their clinical implications.

Mitotic count (MC) is an important prognostic indicator in gastrointestinal stromal tumours (GISTs). Though MC evaluation was initially proposed in 50 HPFs, recent international guidelines recommend that MC be performed on 5 mm because HPFs may have different areas depending on the ocular field number (FN) of the utilized light microscope. Performing MC on different areas leads to a non-standardized evaluation and erroneous risk stratification.

Outstanding Response in a Patient With ROS1-Rearranged Inflammatory Myofibroblastic Tumor of Soft Tissues Treated With Crizotinib: Case Report.

Inflammatory myofibroblastic tumor (IMT) is a very rare subtype of sarcoma, which frequently harbor chromosomal rearrangements, including anaplastic lymphoma kinase (ALK) rearrangements (almost 50% of the IMTs) and other kinase fusions such as ROS1. ROS1 fusions are present in about 10% of IMT, almost half of the ALK-negative IMT patients. Apart from radical surgery for resectable tumors, there is no standard-of-care therapy for advanced IMTs.

Pharmacokinetics, safety, and activity of trabectedin as first-line treatment in elderly patients who are affected by advanced sarcoma and are unfit to receive standard chemotherapy: A phase 2 study (TR1US study) from the Italian Sarcoma Group.

Background: Although elderly patients (≥70 years) represent 30% of new diagnoses of soft tissue sarcoma (STS), they are underrepresented in clinical trials and are often unfit to receive standard anthracycline-based chemotherapy. Trabectedin is registered as a second-line treatment for advanced STS and is characterized by a favorable safety profile.

Methods: The aim of this single-arm, phase 2 study was to investigate trabectedin (scheduled dose, 1.

Gastrointestinal stromal tumors and second primary malignancies: a retrospective monocentric analysis.

In the post-Imatinib era, the median survival of patients diagnosed with GIST has reached almost 5 years. Prolonging GIST-specific survival, GIST patients have an increased incidence of secondary neoplasia. Data on the prognostic impact of second tumors in GIST patients are very poor with few and small retrospective analyses available in the literature.

Targeted Deep Sequencing Uncovers Cryptic KIT Mutations in KIT/PDGFRA/SDH/RAS-P Wild-Type GIST.

Gastrointestinal stromal tumors (GIST) are known to carry oncogenic KIT or PDGFRA mutations, or less commonly SDH or NF1 gene inactivation, with very rare cases harboring mutant BRAF or RAS alleles. Approximately 10% of GISTs are devoid of any of such mutations and are characterized by very limited therapeutic opportunities and poor response to standard treatments. Twenty-six sporadic KIT/PDGFRA/SDH/RAS-pathway wild type GIST were profiled for the molecular status of genes frequently altered in GIST by a targeted next generation sequencing (NGS) approach.

Multiple systemic treatment options in a patient with malignant tenosynovial giant cell tumour.

Tenosynovial giant cell tumour (TGCT) is a group of rare soft tissues neoplasia affecting synovial joints, bursae and tendon sheaths and is classified as localized type or diffuse type. The diffuse type (TGCT-D), also known as 'pigmented villonodular (teno)synovitis' is characterized by local aggressivity, with invasion and destruction of adjacent soft-tissue structures, and high local recurrence rate. Radical surgery remains the standard therapy while adjuvant radiotherapy may help to control local spread.

Synchronous GISTs associated with multiple sporadic tumors: a case report.

Gastrointestinal stromal tumors (GISTs) are rare neoplasms, but they also represent the most common mesenchymal tumors of the gastrointestinal tract originating from the cell of Cajal. GIST incidence ranges around 1% of all gastrointestinal malignancies. Approximately 5% of all GISTs have a hereditary etiology.

Molecular characterization of an Italian series of sporadic GISTs.

Purpose: Gastrointestinal stromal tumors (GISTs) are mesenchymal tumors of the gastrointestinal tract. Most (80 %) contain activating mutations in the KIT receptor tyrosine kinase, roughly 10 % in platelet-derived growth factor receptor-alpha (PDGFRA). In a small subset, BRAF mutations are an alternative molecular pathway.

Two doses of NGR-hTNF in combination with capecitabine plus oxaliplatin in colorectal cancer patients failing standard therapies.

Background: asparagine-glycine-arginine-human tumour necrosis factor (NGR-hTNF), an agent selectively damaging the tumour vasculature, showed a biphasic dose-response curve in preclinical models. Previous phase I trials of NGR-hTNF indicated 0.8 and 45 μg/m(2) as optimal biological and maximum-tolerated dose, respectively.

First-line single-agent cetuximab in patients with advanced colorectal cancer.

Background: The anti-epidermal growth factor receptor (EGFR) antibody cetuximab is active in heavily pretreated patients with metastatic colorectal cancer (mCRC) both in monotherapy and in combination with chemotherapy (CT). This study assesses the antitumor activity of single-agent cetuximab in CT-naive patients.

Patients And Methods: Phase II clinical trial was used.

Association of progression-free survival with patient-reported outcomes and survival: results from a randomised phase 3 trial of panitumumab.

In a randomised phase 3 trial, panitumumab significantly improved progression-free survival (PFS) in patients with refractory metastatic colorectal cancer (mCRC). This analysis characterises the association of PFS with CRC symptoms, health-related quality of life (HRQoL), and overall survival (OS). CRC symptoms (NCCN/FACT CRC symptom index, FCSI) and HRQoL (EQ-5D) were assessed for 207 panitumumab patients and 184 best supportive care (BSC) patients who had at least one post-baseline patient-reported outcome (PRO) assessment.

[Surgical resection of gastrointestinal stromal tumor after treatment with imatinib: clinical case].

The stromal tumor is the most common mesenchymal tumor of the gastrointestinal tract. Surgical resection is the first-line therapy for operable lesions, however for inoperable imatinib is an effective therapy. In this setting a patient has been operated after a remarkable response to imatinib, used as both neoadjuvant and adjuvant.

Pemetrexed in gastric cancer.

Gastric cancer is a major clinical challenge, with poor overall prognosis and limited life expectancy for patients with advanced disease. Even with surgery and other modalities, palliation is often difficult. Improvement of response rates has evolved with the development of standard regimens and those incorporating newer chemotherapy agents, such as oral fluoropyrimidines, the taxanes, camptothecins, novel platinums (eg, oxaliplatin [Eloxatin]), and antifolates (eg, pemetrexed [Alimta]).

Life expectancy, comorbidity and quality of life: the treatment equation in the older cancer patients.

With ageing, function preservation and maintenance of quality of life represent a major goal in an increasing proportion of patients. Life expectancy is a function of age, comorbidity, disability and cancer type and stage. Decision-making involves a delicate balance among all these factors, evaluation of treatment related complications of the overall effects of cancer and cancer treatment on the patients' quality of life.

Formestane is feasible and effective in elderly breast cancer patients with comorbidity and disability.

Age is a major risk factor for solid tumors, including breast cancer. The majority of elderly breast cancer patients have oestrogen-dependent tumors, thus, tamoxifen is widely administered. However, it has been noted that tamoxifen-related thrombotic events are not exceptional.

Cancer in the elderly: assessing patients for fitness.

As aging is highly heterogeneous, the clinical evaluation of the older person with cancer is influenced by several factors including comorbid conditions, disabilities, tumour type and stage. Assessment of comorbidity and disability represent on evolving area of research. Results from geriatrics are now translating in clinical oncology.

Is salvage chemotherapy for metastatic breast cancer always effective and well tolerated? A phase II randomized trial of vinorelbine versus 5-fluorouracil plus leucovorin versus combination of mitoxantrone, 5-fluorouracil plus leucovorin.

Metastatic breast cancer remains an incurable disease and the median overall survival has not significantly improved over the past two decades. Aims of the present randomized phase II trial were to analyse activity and toxicity of chemotherapies with single agent or with combination regimens in previously treated patients with advanced breast cancer. Ninety-nine eligible patients were randomized to receive the following chemotherapies: Arm A - vinorelbine 30 mg/m2 i.
