Circulating Tumor DNA Using Tagged Targeted Deep Sequencing to Assess Minimal Residual Disease in Breast Cancer Patients Undergoing Neoadjuvant Chemotherapy.

In breast cancer patients undergoing neoadjuvant chemotherapy before surgery, there is an unmet need for noninvasive predictive biomarkers of response. The analysis of circulating tumor DNA (ctDNA) in particular has been the object of several reports, but few of them have studied the applicability of tagged targeted deep sequencing (tTDS) to clinical practice and its performance compared with droplet digital PCR (ddPCR). Here, we present the first results from an ongoing study involving a prospectively accrued, monocentric cohort of patients affected by invasive breast cancer, undergoing neoadjuvant chemotherapy followed by surgery with curative intent as per clinical practice.

Development of a long non-coding RNA signature for prediction of response to neoadjuvant chemoradiotherapy in locally advanced rectal adenocarcinoma.

Standard treatment for locally advanced rectal adenocarcinoma (LARC) includes a combination of chemotherapy with pyrimidine analogues, such as capecitabine, and radiation therapy, followed by surgery. Currently no clinically useful genomic predictors of benefit from neoadjuvant chemoradiotherapy (nCRT) exist for LARC. In this study we assessed the expression of 8,127 long noncoding RNAs (lncRNAs), poorly studied in LARC, to infer their ability in classifying patients' pathological complete response (pCR).

Comparisons between glucose analogue 2-deoxy-2-((18)F)fluoro-D-glucose and (18)F-sodium fluoride positron emission tomography/computed tomography in breast cancer patients with bone lesions.

Aim: To compare 2-deoxy-2-((18)F)fluoro-D-glucose((18)F-FDG) and (18)F-sodium ((18)F-NaF) positron emission tomography/computed tomography (PET/CT) accuracy in breast cancer patients with clinically/radiologically suspected or known bone metastases.

Methods: A total of 45 consecutive patients with breast cancer and the presence or clinical/biochemical or radiological suspicion of bone metastatic disease underwent (18)F-FDG and (18)F-fluoride PET/CT. Imaging results were compared with histopathology when available, or clinical and radiological follow-up of at least 1 year.

Sequential dose-dense 5-fluorouracil, epirubicin and cyclophosphamide followed by docetaxel in patients with early breast cancer with four or more positive lymph nodes.

Aim: The aim of present study was to investigate the feasibility of a densified sequence of FEC75 (5-fluorouracil 600 mg/m2, epirubicin 75 mg/m2, cyclophosphamide 600 mg/m2) and docetaxel 100 mg/m2 (D100) in patients with primary operable high-risk breast cancer.

Methods: Fifty-one consecutive patients with resectable breast cancer and 4 or more positive axillary lymph nodes were enrolled. After a common regimen of 4 cycles of FEC75 given every 14 days, patients received 4 cycles of D100 every 14 days.

Autologous stem cell transplantation for aggressive lymphomas.

The role of high-dose therapy (HDT) followed by autologous stem cell transplantation (ASCT) in the treatment armamentarium of aggressive B- and T-cell non-Hodgkin lymphoma (NHL) is still a matter of debate. In the pre-Rituximab era, the PARMA study demonstrated the superiority of HDT/ASCT over conventional salvage chemotherapy in chemosensitive, relapsed patients. Subsequently, HDT/ASCT has become a standard approach for relapsed NHL.

Therapy of Hodgkin's lymphoma in clinical practice: A retrospective long-term follow-up analysis.

Treatment of Hodgkin's lymphoma (HL) is perceived to be relatively straightforward. Consequently, patients are not usually referred to hemato-oncologically specialized centres and are treated locally instead. Comprehensive findings beyond prospective controlled trials are therefore lacking.

sHLA-I contaminating molecules as novel mechanism of ex vivo/in vitro transcriptional and posttranscriptional modulation of transforming growth factor-beta in CD8+ T lymphocytes and neutrophils after intravenous immunoglobulin treatment.

Background: Numerous mechanisms have been proposed to explain the beneficial action of intravenous immune globulin (IVIG) in autoimmune and systemic inflammatory disorders. Among others' data, an in vitro increase of intracellular TGF-beta expression when culturing CD4+ T lymphocytes in the presence of IVIG has been reported. As IVIG infusion involves administration of soluble contaminants likewise all hemoderivative preparations, we hypothesized that, besides several other immunomodulatory proposed mechanisms, the clinical effects of IVIG therapy might be, at least partly, due to contaminating soluble HLA Class I (sHLA-I) molecules capable to exert pleiotropic immunomodulatory effects among which TGF-beta(1) modulation.

Pegfilgrastim compared with filgrastim after autologous peripheral blood stem cell transplantation in patients with solid tumours and lymphomas.

To evaluate the safety and efficacy of pegfilgrastim administered as haematological support after autologous peripheral blood stem cell transplantation, we compared 44 patients with solid tumours and lymphomas receiving a 6-mg single dose of pegfilgrastim on day +5 after transplantation to a historical control group of 25 patients receiving filgrastim 5 microg kg(-1) day(-1) starting on day +5. There were no significant differences in haematological recovery nor in the incidence and duration of neutropenic fever. Median duration of grade 4 neutropenia in the pegfilgrastim and filgrastim group was similar.

Reduced intensity conditioning for allograft after cytoreductive autograft in metastatic breast cancer.

The benefits of allografting noted in some malignant diseases might be safely extended to metastatic breast cancer by a combination of cytoreduction with high-dose chemotherapy (HDT) and autologous stem-cell transplant (ASCT) with graft-versus-tumour effect mediated by transplanted donor immune cells with nonmyeloablative allografting (reduced intensity conditioning transplantation, RICT). 17 patients with heavily pretreated disease were given tandem transplants. 13 patients sustained donor engraftment.

Dose-dense vinorelbine and paclitaxel with granulocyte colony-stimulating factor in metastatic breast cancer patients: anti-tumor activity and peripheral blood progenitor cell mobilization capability.

We studied the safety, activity and peripheral blood progenitor cell mobilizing capability of a dose-dense combination of vinorelbine (VNB) and paclitaxel (PTX) as first-line chemotherapy for patients with metastatic breast cancer (MBC). Forty-three MBC patients were submitted to four cycles of VNB 30 mg/m2 and PTX 175 mg/m2 intravenously, every 2 weeks, as the first induction step of a tandem high-dose chemotherapy program. Granulocyte colony-stimulating factor (G-CSF) 5 microg/kg was administered daily from day +5 to +10 in order to accelerate hematopoietic recovery, or 48h after the last VNB-PTX when a leukapheresis was planned (after the third or fourth cycle).

Three-step high-dose sequential chemotherapy in patients with newly diagnosed multiple myeloma.

Background And Objectives: High-dose chemotherapy (HDT) with autologous peripheral blood progenitor cell (PBPC) transplant has been increasingly used for newly diagnosed multiple myeloma (MM) in recent years. Presently available results suggest an improvement in the complete remission rate and survival as compared to conventional chemotherapy. However, there is no plateau in the survival curves, and experiments with new treatment schedules and conditioning regimens are warranted.
