Article Synopsis
  • Glioblastoma (GBM) is a highly aggressive brain tumor with a poor prognosis, typically treated with surgery followed by radiotherapy and temozolomide; a trial is assessing the addition of Dendritic Cell vaccination (DCvax) to standard therapy.* ! -
  • The study is a phase II trial involving 9 patients, focusing on progression-free survival (PFS) and safety, with DCvax administered after standard treatment and showing promising early immune response results.* ! -
  • Initial findings indicate that the combination therapy is well-tolerated and achieves the initial study endpoints, allowing enrollment of additional patients to continue the research.* !

The identification of predictive factors for treatment of pancreatic cancer (PC) is an unmet clinical need. In the present work, we analyzed blood-derived extracellular vesicles (EVs) from patients with advanced PC in order to find a molecular signature predictive of response to therapy. We analyzed samples from 21 patients with advanced PC, all receiving first-line treatment with gemcitabine + nab-paclitaxel.

Background And Purpose: In this study we want to evaluate the efficacy of yoga practice on dysfunctional stress, inflammation and QOL in breast cancer patients undergoing adjuvant radiotherapy.

Patients And Methods: Patients with stage 0 to III breast cancer were recruited before starting radiotherapy (XRT) and were randomly assigned to yoga group (YG) two times a week during XRT or control group (CG). Self-report measures of QOL, fatigue and sleep quality, and blood samples were collected at day 1 of treatment, day 15, end of treatment and 1, 3 and 6 months later.

The immune system is a dynamic feature of each individual and a footprint of our unique internal and external exposures. Indeed, the type and level of exposure to physical and biological agents shape the development and behavior of this complex and diffuse system. Many pathological conditions depend on how our immune system responds or does not respond to a pathogen or a disease or on how the regulation of immunity is altered by the disease itself.

High-dose interleukin-2 (HD IL-2) has curative potential in metastatic melanoma (MM) and renal cell carcinoma (RCC). Radiotherapy (RT) kills cancer cells and induces immunomodulatory effects. Prospective trials exploring clinical and immunological properties of combined RT/HD IL-2 are still needed.

Dendritic cell (DC)-based vaccination effectively induces anti-tumor immunity, although in the majority of cases this does not translate into a durable clinical response. However, DC vaccination is characterized by a robust safety profile, making this treatment a potential candidate for effective combination cancer immunotherapy. To explore this possibility, understanding changes occurring in the tumor microenvironment (TME) upon DC vaccination is required.

Article Synopsis
  • Surgery is a common treatment for melanoma patients with a single metastasis, but it often isn't curative; combining surgery with dendritic cell (DC) immunotherapy may improve survival rates.
  • Patients showing delayed type hypersensitivity (DTH) after DC vaccination had significantly longer overall survival compared to those without DTH; a phase II trial indicated that DC vaccines performed better than tumor cell-based ones.
  • A new phase II randomized trial aims to compare the effectiveness of DC vaccines versus standard follow-up care in patients with resected stage III/IV melanoma, with plans for monitoring various health metrics and ethical approval already obtained.

Although immunomodulating antibodies are highly effective in metastatic melanoma, their toxicity, related to the activation of T lymphocytes, can be severe. Anticancer vaccines promote a fairly specific response and are very well tolerated, but their effectiveness has yet to be demonstrated. We have been treating patients with advanced melanoma with an autologous dendritic cell vaccine since 2001; to better characterize the safety and efficacy of our product, we designed a retrospective study on all of our patients treated with the vaccine to date.

Istituto Scientifico Romagnolo per lo Studio e la Cura dei Tumori (IRST) IRCCS is a public-private partnership among 3 public sector bodies and 6 private nonprofit organizations and represents the hub of the Oncology Network of Romagna, which provides a wide range of services for the population ranging from primary prevention to palliative care. In 2012, IRST took part in the ministerial research project of the Organisation of European Cancer Institutes (OECI) accreditation program for Comprehensive Cancer Centers. The self-assessment period lasted 6 months and was coordinated by a multidisciplinary project team headed by a project leader.

Background: Vaccination with dendritic cells (DC) loaded with tumor antigens elicits tumor-specific immune responses capable of killing cancer cells without inducing meaningful side-effects. Patients with advanced melanoma enrolled onto our phase II clinical studies have been treated with autologous DC loaded with autologous tumor lysate/homogenate matured with a cytokine cocktail, showing a clinical benefit (PR + SD) in 55.5% of evaluable cases to date.

A panel of experts from Italian Comprehensive Cancer Centers defines the recommendations for external quality control programs aimed to accreditation to excellence of these institutes. After definition of the process as a systematic, periodic evaluation performed by an external agency to verify whether a health organization possesses certain prerequisites regarding structural, organizational and operational conditions that are thought to affect health care quality, the panel reviews models internationally available and makes final recommendations on aspects considered of main interest. This position paper has been produced within a special project of the Ministry of Health of the Italian Government aimed to accredit, according to OECI model, 11 Italian cancer centers in the period 2012-2014.

Article Synopsis
  • Dendritic cells (DCs) help the body's immune system fight cancer, but there are challenges because certain cells (Foxp3+Tregs) can turn off the immune response.
  • The study involved 21 patients with advanced melanoma receiving a special vaccine made from their own tumor cells and a chemotherapy drug called temozolomide to help boost the vaccine's effect.
  • Although the study showed some positive effects, like reducing the number of Foxp3+Treg cells, it didn't produce a big improvement in overall patient outcomes, meaning it didn't help everyone get better.

Dendritic cells (DCs) are unique specialized antigen-presenting cells capable of priming naive T cells and inducing antigen-specific cytotoxic T lymphocytes. This study presents an update of clinical results from a DC-based phase I-II clinical vaccine trial in stage IV melanoma. From 2003 to 2010, 27 patients with metastatic melanoma were treated with mature DCs pulsed with autologous tumor lysate and keyhole limpet hemocyanin and with subcutaneous low-dose interleukin-2.

We reviewed the clinical results of a dendritic cell-based phase II clinical vaccine trial in stage IV melanoma and analyzed a patient subgroup treated with standard therapies after stopping vaccination. From 2003 to 2009, 24 metastatic melanoma patients were treated with mature dendritic cells pulsed with autologous tumor lysate and keyhole limpet hemocyanin and low-dose interleukin-2. Overall response (OR) to vaccination was 37.

Background: Antigen processing by dendritic cells (DC) exposed to specific stimuli has been well characterized in biological studies. Nonetheless, the question of whether autologous whole tumor lysates (as used in clinical trials) are similarly processed by these cells has not yet been resolved.

Methods: In this study, we examined the transfer of peptides from whole tumor lysates to major histocompatibility complex class II molecules (MHC II) in mature dendritic cells (mDC) from a patient with advanced melanoma.

The synthesis and physical-chemical characterization of the metal-ligand complex [Os(bpy)2(CO)(enIA)][OTf]2 (where enIA = ethylenediamine iodoacetamide) with a sulfhydryl-specific functional group is described. The UV and visible absorption and luminescence emission, including lifetime and steady-state anisotropy, are reported for the free probe and the probe covalently linked to two test proteins. The spectroscopic properties of the probe are unaffected by chemical modification and subsequent covalent linkage to the proteins.
