MIAmS: microsatellite instability detection on NGS amplicons data.

Motivation: Microsatellite instability (MSI) is a molecular marker of DNA mismatch repair deficiency frequently at play in oncogenesis. MSI testing is used for diagnostic, prognostic and therapeutic purposes in several cancers. The current gold standard analysis for microsatellite status is based on length distribution analysis of multiplex-PCR generated DNA fragments from tumor samples which is a laborious and time consuming method.

Early F-FDG PET/CT Response Predicts Survival in Relapsed or Refractory Hodgkin Lymphoma Treated with Nivolumab.

Monoclonal antibodies (mAbs) against programmed cell death 1 (PD-1), such as nivolumab and pembrolizumab, are associated with high response rates in patients with relapsed or refractory classic Hodgkin lymphoma (HL). To date, no prognostic factor for overall survival (OS) has been established with these agents in HL. We examined whether the first early response assessment evaluated using F-FDG PET/CT may be associated with OS in this setting.

Active surveillance eligibility of MRI-positive patients with grade group 2 prostate cancer: a pathological study.

Purpose: To assess the final pathology risk in MRI-positive grade group (GG) 2 prostate cancer (PCa) patients undergoing targeted (TB) and systematic (SB) biopsies, and thereby, the possibility of active surveillance (AS) in this population.

Patients And Methods: We included 242 consecutive men diagnosed with GG2 PCa by a combination of SB and software-based fusion TB undergoing a radical prostatectomy (RP). The primary endpoints were the pathological findings in RP specimens, including favourable disease which was defined by a pT2 and GG1-2 disease.

Objective: The purpose of the guidelines national committee ccAFU was to propose updated French guidelines for prostate cancer.

Methods: A Medline search was achieved between 2016 and 2018, as regards diagnosis, options of treatment and follow-up of prostate cancer, and to evaluate the different references specifying their levels of evidence.

Results: Epidemiology, classification, staging systems, diagnostic evaluation of prostate cancer are reported.

Prophylactic, preemptive, and curative treatment for sinusoidal obstruction syndrome/veno-occlusive disease in adult patients: a position statement from an international expert group.

Sinusoidal obstruction syndrome, also known as veno-occlusive disease (SOS/VOD), is a potentially life-threatening complication that can develop after hematopoietic cell transplantation (HCT). While SOS/VOD may resolve within a few weeks in the majority of patients with mild-to-moderate disease, the most severe forms result in multiorgan dysfunction and are associated with a high mortality rate (>80%). Therefore, careful surveillance may allow early detection of SOS/VOD, particularly as the licensed available drug is proven to be effective and reduce mortality.

Low level CpG island promoter methylation predicts a poor outcome in adult T-cell acute lymphoblastic leukemia.

Cancer cells undergo massive alterations in their DNA methylation patterns which result in aberrant gene expression and malignant phenotypes. Abnormal DNA methylation is a prognostic marker in several malignancies, but its potential prognostic significance in adult T-cell acute lymphoblastic leukemia (T-ALL) is poorly defined. Here, we performed methylated DNA immunoprecipitation to obtain a comprehensive genome-wide analysis of promoter methylation in adult T-ALL (n=24) compared to normal thymi (n=3).

Effect of Extended Pelvic Lymph Node Dissection on Oncologic Outcomes in Patients with D'Amico Intermediate and High Risk Prostate Cancer Treated with Radical Prostatectomy: A Multi-Institutional Study.

Purpose: Pelvic lymph node dissection represents the gold standard of lymph node staging in patients with prostate cancer. We sought to assess the effect of extended pelvic lymph node dissection on oncologic outcomes in patients with characteristics of D'Amico intermediate or high risk prostate cancer treated with radical prostatectomy.

Materials And Methods: In a multi-institutional database of 4 centers we identified 9,742 patients who underwent radical prostatectomy from 2000 to 2017 with or without pelvic lymph node dissection.

A simplified frailty scale predicts outcomes in transplant-ineligible patients with newly diagnosed multiple myeloma treated in the FIRST (MM-020) trial.

Patients with multiple myeloma are generally older and vary in fitness levels, which may influence the clinical benefit of treatment. Patients from the large, phase 3 FIRST trial in newly diagnosed multiple myeloma (NDMM) were retrospectively investigated to determine outcomes based on frailty using scores for age, Charlson Comorbidity Index (CCI), and Eastern Cooperative Oncology Group performance status (ECOG PS), instead of the EQ-5D quality-of-life questionnaire, as previously reported. ECOG PS (n = 1618) was investigated in frailty groups: frail (49%) and nonfrail (51%).

Incidence and outcome of BCR-ABL mutated chronic myeloid leukemia patients who failed to tyrosine kinase inhibitors.

Purpose: To assess the incidence of BCR-ABL kinase domain (KD) mutation detection and its prognostic significance in chronic phase chronic myeloid leukemia (CP-CML) patients treated with tyrosine kinase inhibitors (TKIs).

Patients And Methods: We analyzed characteristics and outcome of 253 CP-CML patients who had at least one mutation analysis performed using direct sequencing. Of them, 187 patients were early CP (ECP) and 66 were late CP late chronic phase (LCP) and 88% were treated with Imatinib as first-line TKI.

[A new terminology for urinary cytopathology: The Paris System for Reporting Urinary Cytology (2015)].

As for the Bethesda system for cervical and thyroid cytopathology, a terminology for reporting urinary cytology has been published in 2015. The new "Paris System" provides a consensus terminology for urinary cytology which underlines the criteria for the recognition of high-grade urothelial carcinoma (HGUC) and of those excluding HGUC, or suspicious for HGUC. It also focuses on new rules to recognize and report the subgroup of "atypical urothelial cells".

Added Value of Concomitant Systematic and Fusion Targeted Biopsies for Grade Group Prediction Based on Radical Prostatectomy Final Pathology on Positive Magnetic Resonance Imaging.

Purpose: We assessed the added value of concomitant systematic biopsy for final grade group prediction in patients with positive magnetic resonance imaging who were undergoing targeted biopsy.

Materials And Methods: Included in study were 478 consecutive patients with prebiopsy positive multiparametric magnetic resonance imaging and a greater than 10-core systematic biopsy combined with fusion targeted biopsy who underwent radical prostatectomy. The primary end point was the grade group concordance between biopsy and radical prostatectomy pathology according to the biopsy technique.

Individualized prediction of leukemia-free survival after autologous stem cell transplantation in acute myeloid leukemia.

Background: Autologous stem cell transplantation (ASCT) is a potential consolidation therapy for acute myeloid leukemia (AML). This study was designed to develop a prediction model for leukemia-free survival (LFS) in a cohort of patients with de novo AML treated with ASCT during their first complete remission.

Methods: This was a registry study of 956 patients reported to the European Society for Blood and Marrow Transplantation.

Performance of systematic, MRI-targeted biopsies alone or in combination for the prediction of unfavourable disease in MRI-positive low-risk prostate cancer patients eligible for active surveillance.

Purpose: To assess the upstaging/upgrading rates of low-risk prostate cancer (PCa) according to the biopsy scheme used (systematic (SB), targeted biopsies (TB), or both) in the setting of positive pre-biopsy MRI.

Patients And Methods: We included 143 consecutive men fulfilling the Toronto University active surveillance (AS) criteria who underwent a pre-biopsy positive MRI, a combination of SB and software-based fusion TB, and a radical prostatectomy, in two expert centres. The primary endpoints were the pathological upgrading and upstaging rates.

Multifocal recurrence on the transaxillary robotic thyroidectomy incision.

Introduction: Robotic thyroidectomy (RT) has been reported to achieve satisfactory results. However, its long-term oncological results have not been validated. The use of RT to treat thyroid cancer comprises specific risks that are not encountered with open thyroidectomy (OT).

Tumor Cells Hijack Macrophage-Produced Complement C1q to Promote Tumor Growth.

Clear-cell renal cell carcinoma (ccRCC) possesses an unmet medical need, particularly at the metastatic stage, when surgery is ineffective. Complement is a key factor in tissue inflammation, favoring cancer progression through the production of complement component 5a (C5a). However, the activation pathways that generate C5a in tumors remain obscure.

[Securing patients pathways treated by oral antitumoral: Guidelines for better organization of departments and management of incoming calls].

The emergence of oral cancer treatment in oncology has shifted patient follow-up from the hospital to the home. This trend has resulted in an increase in phone and e-mail interactions initiated by patients, but also by pharmacists, by liberal nurses, by general practitioners, and an increase in calls to the emergency response services (SAMU) both for real or perceived emergencies. This increased volume of patient and pharmacist communication has caused significant disruption in the daily activity of affected oncology departments and in particular of the secretariats.

Prospective phase II study of prophylactic low-dose azacitidine and donor lymphocyte infusions following allogeneic hematopoietic stem cell transplantation for high-risk acute myeloid leukemia and myelodysplastic syndrome.

Thirty patients, with high-risk acute myeloid leukemia (AML, n = 20) or myelodysplastic syndrome (MDS, n = 10), were enrolled in a phase II trial entailing prophylactic post-transplant azacitidine (AZA) plus escalated doses of donor lymphocyte infusion (DLI). The median number of AZA cycles was 5 (1-12) with 10 patients (33%) completing the 12 projected cycles. DLI were performed in 17 patients: 5 received one DLI, 2 received 2 DLI and 8 received 3 infusions.

Long-term efficacy of anti-PD1 therapy in Hodgkin lymphoma with and without allogenic stem cell transplantation.

Introduction: Long-term efficacy of anti-PD1 therapy and the need for a consolidation with allogenic haematopoietic stem cell transplantation (allo-HSCT) remain unclear in patients with relapsed/refractory (R/R) Hodgkin lymphoma (HL).

Methods: We retrospectively analysed 78 patients with R/R HL treated with nivolumab in the French Early Access Program and compared their outcomes according to subsequent allo-HSCT.

Results: After a median follow-up of 34.

Receptor radionuclide targeting for neuroendocrine tumors (NET) diagnostic and therapy.

Neuroendocrine tumors (NET) represent a heterogeneous group of tumors originating from cells of neuroendocrine origin, which express somatostatin receptors (SSTR). This property allowed the successful development of radionuclides for diagnostic and peptide radionuclide radiation therapy (PRRT). This is the paradigm for the theragnostic concept in NET personalized medicine.

Ultra-sensitive Detection as an Independent Prognostic Marker for Lung Cancer Patients Harboring Mutations and Treated with First-generation TKIs.

Purpose: The detection of preexisting subclones and the assessment of their clinical significance in the pretreatment of patients with non-small cell lung cancer (NSCLC) remain unclear.

Experimental Design: A total of 179 tumor samples from patients treated or not with a first-generation tyrosine kinase inhibitor (TKI) was analyzed. The presence of ultra-low levels of preexisting EGFR mutation was evaluated using ultra-sensitive droplet digital PCR (ddPCR) and the clinical implication of these mutations on first-generation TKI efficiency assessed.
