Coexistence of p16/CDKN2A homozygous deletions and activating EGFR mutations in lung adenocarcinoma patients signifies a poor response to EGFR-TKIs

Lung adenocarcinoma patients with epidermal growth factor receptor (EGFR)-activating mutation and genotype p16/CDKN2A homozygous deletion (n = 31) were compared with those without the deletion (n = 96) relative to their response to EGFR-TKI therapy. The deletion was associated with overall poorer response (P = .0027) and lower median PFS (5.3 months vs 10.5 months). […]

Decision Analysis of Post-Remission Therapy in Cytogenetically Intermediate-Risk AML

Whether FLT3-ITD, NPM1, and CEBPA mutation statuses were associated with treatment outcomes in patients who had undergone allogeneic hematopoietic cell transplantation (allo-HCT) and chemotherapy for AML was investigated in this retrospective study. Of 332 patients with AML in first complete remission (CR1), 85 had undergone allo-HCT. FLT3-ITD was present in 60 patients, NPM1 in 83,

HER2 gene amplification testing by Fluorescent in situ hybridization (FISH)

A recent study evaluated the impact of guidelines surrounding the use of fluorescent in situ hybridization (FISH) to determine degree of HER2 gene amplification. Patients remain very confused about how HER2 receptor tests are performed, why there are different ways of doing the tests, and, more concerning, how the tests are interpreted. It is such a

Ibrutinib Effective for Patients with Relapsed or Refractory Chronic Lymphocytic Leukaemia With 17p Deletion

The authors in this multicenter, single-arm, open-label study evaluated the safety and efficacy of ibrutinib in 145 patients with relapsed or refractory del17p chronic lymphocytic leukemia (CLL). Overall response rate at 27.6 months was 83%. Additionally, 2-year progression-free and overall survivals were 63% and 75%, respectively. Grade 3 or worse infection rate was 30%. The

Sole rearrangement but not amplification of MYC is associated with a poor prognosis in patients with diffuse large B cell lymphoma and B cell lymphoma unclassifiable.

Rearrangement of MYC is associated with a poor prognosis in patients with diffuse large B cell lymphoma (DLBCL) and B cell lymphoma unclassifiable (BCLU), particularly in the setting of double hit lymphoma (DHL). However, little is known about outcomes of patients who demonstrate MYC rearrangement without evidence of BCL2 or BCL6 rearrangement (single hit) or

7q32

The diagnosis of splenic marginal zone lymphoma (SMZL) is frequently a challenge, due to its lack of specific histological features and immunophenotypic markers, and the existence of other poorly characterized splenic lymphomas defying classification. The 7q32 deletion is a characteristic feature of SMZL, and its detection may help the differential diagnosis of splenic B-cell lymphomas.

Cobimetinib combined with vemurafenib in advanced BRAFV600-mutant melanoma (coBRIM): updated efficacy results from a randomised, double-blind, phase 3 trial.

The combination of cobimetinib with vemurafenib improves progression-free survival compared with placebo and vemurafenib in previously untreated patients with BRAFV600-mutant advanced melanoma, as previously reported in the coBRIM study. In this Article, we report updated efficacy results, including overall survival and safety after longer follow-up, and selected biomarker correlative studies. In this double-blind, randomised, placebo-controlled,

Neuroblastomas: biologic and molecular features

On the basis of biologic factors and an improved understanding of the molecular development of the neural crest cells that give rise to neuroblastoma, neuroblastic tumors have been categorized into the following three biological types: Type 1:Characterized by gains and losses of whole chromosomes. It expresses the TrkA neurotrophin receptor, is hyperdiploid, and tends to

Small Panel of FISH Cytogenetic Markers Distinguishes Risk in Medulloblastoma Subgroups

In a recent study, molecular biomarkers were identified from an international discovery set of 673 medulloblastoma cases from the Medulloblastoma Advanced Genomics International Consortium. Risk stratification models were designed based on combined clinical and cytogenetic biomarkers identified in multivariable Cox proportional hazards analyses. Candidate biomarkers were tested using fluorescence in situ hybridization (FISH) on a
