Stage I non-Hodgkin lymphoma: no plateau in disease-specific survival ?

AbstractStage I non-Hodgkin lymphoma (NHL) is rare; prognostic impact of different histologic subtypes and treatment modality is still unclear. We used the Surveillance, Epidemiology and End Results (SEER) database to evaluate survival outcomes among adult patients (age  ≥ 18 years,N = 58,230) diagnosed with stage I NHL of various histologic subtypes between 1998 and 2014. Five-year disease-specific survival of patients with stage I diffuse large B cell lymphoma (DLBCL), follicular lymphoma (FL), marginal zone lymphoma (MZL), small lymphocytic lymphoma (SLL), Burkitt lympho ma (BL), mantle cell lymphoma (MCL), and peripheral T cell lymphoma (PTCL) was 82%, 92%, 95%, 89%, 78%, 77%, and 77%, respectively. The median disease-specific survival was not reached in all histologic subtypes analyzed; however, there does not appear to be a plateau in disease-specific survival of patients with stage I NHL irrespective of subtypes. Although lymphoma was the most common cause of death (40.7%), death from other cancer (17.4%) and cardiovascular disease (13.6%) were also frequent. Chemotherapy appeared favorably associated with OS in patients with DLBCL, BL, and MCL while patie nts with FL, MZL, SLL, and PTCL who require chemotherapy for initial treatment showed shorter OS. Patients with stage I NHL have favorable disease-specific survival; however, no plateau was seen regardless of histologic subtypes thus suggesting that patients may need attention and ...

Authors: Musio F Abstract INTRODUCTION: Anemia has and will continue to be a central theme in medicine particularly as clinicians are treating a burgeoning population of complex multi-organ system processes. As a result of multiple randomized controlled trials (RCTs), meta-analyses, and societal recommendations overly restrictive paradigms and under-administration of erythropoiesis stimulating agents (ESAs) have likely been followed by clinicians among all specialties. AREAS COVERED: A review of anemia in the context of chronic kidney disease, hematologic malignancies and cancer is presented with focus on the e...

Authors: Matti B, Zargar-Shoshtari K Abstract Prostate cancer represents a significant health burden worldwide. The cancer incidence had substantially increased since the introduction of prostate specific antigen (PSA) in cancer screening. This had led to considerable debates among health professionals and epidemiologists, since PSA as a screening tool seemed to be far from perfect. In New Zealand, the controversy was quite prominent in the last three decades, with some advocating the benefits of screening, while others concerned regarding the risk of harms. With the absence of an organised screening programme and ...

CONCLUSION: This study found that childhood cancer survivors in New Zealand had a high prevalence of developmental dental abnormalities and it identified potential risk factors related to their cancer treatment. Inequitable access to oral rehabilitation for this patient group argues for a mechanism for consistent improved access to publicly funded dental care across district health boards in New Zealand.

Authors: Peng C, Cohen DJ Abstract INTRODUCTION: Esophageal squamous cancer remains an important cause of mortality worldwide with two new immunotherapy drugs recently approved for metastatic disease. AREAS COVERED: The authors review the epidemiology and genomics of esophageal squamous cell carcinoma. They also examine prior trials involving targeted agents under investigation as well immunotherapies that have been approved and novel combinations. EXPERT OPINION: Great advances have been made in characterizing the molecular changes in esophageal carcinoma. However, relatively few drugs have shown benefit i...

This article summarizes the rationale for, and development of CDK inhibitors in melanoma, with their evolution from pan-CDK inhibitors to highly specific agents, throughout clinical trials and finally their potential future use. EXPERT OPINION: Whilst CDK inhibitors have been practice changing in breast cancer management, their efficacy is yet to be proven in melanoma. Combination with BRAF/MEK inhibitors has been hindered by dose-limiting toxicities, but their role may yet to be found within the spectrum of biomarker-derived personalized melanoma management. The effect that CDK inhibitors can have as an adjunct to imm...

Discussion In this section, we discuss the mechanisms responsible for lymphomagenesis in the various inborn errors of immunity and provide an overview of the treatment. Defects in Immune Responses That Predispose to Lymphomagenesis in PIDDs The complex immune mechanisms and their interplay that predisposes to neoplastic transformation of B or T cells and development of lymphomas in PIDD patients has not been fully elucidated. However, it is expected that the etiology in most cases is multifactorial and related to a dynamic regulation of immune response and environmental triggers (Figure 3). An underlying intrinsic susce...
