Survival of cancer survivors with a new pancreatic cancer diagnosis.

BACKGROUND: Persons newly diagnosed with pancreas cancer and who have survived a previous cancer are often excluded from clinical trials, despite limited evidence about their prognosis. We examined the association between previous cancer and overall survival. METHODS: This US population-based cohort study included older adults (aged ≥66 years) diagnosed with pancreas cancer between 2005 and 2015 in the linked Surveillance, Epidemiology, and End Results-Medicare data. We used Cox proportional hazards models to estimate stage-specific effects of previous cancer on overall survival, adjusting for sociodemographic, treatment, and tumor characteristics. RESULTS: Of 32,783 patients, 18.7% were previously diagnosed with another cancer. The most common previous cancers included prostate (29.0%), breast (18.9%), or colorectal (9.7%) cancer. More than half of previous cancers (53.9%) were diagnosed 5 or more years prior to pancreas cancer diagnosis or at an in situ or localized stage (47.8%). The proportions of patients surviving 1, 3, and 5 years after pancreas cancer were nearly identical for those with and without previous cancer. Median survival in months was as follows for those with and without previous cancer respectively: 7 versus 8 (Stage 0/I), 10 versus 10 (Stage II), 7 versus 7 (Stage III), and 3 versus 2 (Stage IV). Cox models indicated that patients with previous cancer had very similar or statistically equivalent survival to those with no previous cancer. CONCLUSIONS: Given nearly equivalent survival compared to those without previous cancer, cancer survivors newly diagnosed with pancreas cancer should be considered for inclusion in pancreas cancer clinical trials.

The impact of bridging therapy prior to CD19-directed chimeric antigen receptor T-cell therapy in patients with large B-cell lymphoma.

In the relapsed/refractory setting for treatment of large B-cell lymphoma (LBCL), chimeric antigen receptor T-cell (CAR-T) therapy has emerged as an effective treatment modality. Patients often have aggressive disease that requires prompt treatment in the form of bridging therapy (BT) for disease stabilisation while CAR-T cells are manufactured. Patients (n = 75) undergoing CAR-T therapy infusion for LBCL at our institution were identified. A total of 52 (69·3%) received BT and 23 (30·7%) received no BT (NBT). BT modalities included systemic BT (SBT) in 28 patients, radiation BT (RBT) in 14, and high-dose steroid BT (HDS) in 10. There was no difference in incidence of cytokine release syndrome or immune effector cell-associated neurotoxicity syndrome between BT and NBT (P = 0·18 and P = 0·53 respectively). Prolonged cytopenias at Day 180 were more common in BT than NBT (50% vs. 13·3%, P = 0·04). The SBT and RBT subgroups had more cytopenias at Day 180 compared to the HDS and NBT subgroups (58·3% and 57·1% vs. 20% and 13·3% respectively, P = 0·04). Disease response at last follow-up, progression-free survival and overall survival were similar between BT, NBT, and BT subgroups. In summary, BT can be safely considered in patients undergoing CAR-T therapy. However, those undergoing BT with SBT or RBT are at higher risk of prolonged cytopenias after CAR-T therapy.

Length of Stay and Hospital Costs for Patients Undergoing Allogeneic Stem-Cell Transplantation.

PURPOSE: Patients who undergo allogeneic hematopoietic stem-cell transplantation (allo-HSCT) usually require a prolonged hospital stay that varies greatly across patients. Limited information exists on the factors associated with hospital length of stay (LOS) after allo-HSCT and the impact on transplant-related costs. The objective of this study was to determine predictors for longer LOS for allo-HSCT and to assess their impact on the cost of transplant stay. METHODS: Using the National Inpatient Sample database, adult patients hospitalized for allo-HSCT were identified using International Classification of Diseases, Ninth Revision, primary and secondary procedure codes. RESULTS: Between 2002 and 2015, 68,296 hospitalizations for allo-HSCT were identified. Peripheral blood was the most common stem-cell source (80%) followed by bone marrow (15%) and cord blood (5%). Median LOS was 25.8 days (interquartile range [IQR], 21-34.0 days), and the overall inpatient mortality rate was 8%. Stem-cell source was a significant predictor for longer LOS, being significantly longer for cord blood (median, 36.9 days; IQR, 26.7-49.9 days) compared with bone marrow (median, 27.2 days; IQR, 21.5-35.2 days) and peripheral blood (median 25.4 days; IQR, 20.8-32.7 days). Other predictors for longer LOS were patient characteristics such as age and race, transplant/post-transplant characteristics, and complications such as total body irradiation use, acute graft-versus-host disease, and infections. Longer LOS was also found to be associated with higher hospital costs. CONCLUSION: In patients who undergo allo-HSCT, LOS can be predicted using patient- and transplant-related characteristics as well as post-transplant complications. LOS is also a driver for increased cost, and further efforts are needed to mitigate transplant complications and resource utilization.

Updates in Chimeric Antigen Receptor T-Cell (CAR-T) Therapy for Lymphoma and Leukemia from the Annual Meeting of American Society of Hematology 2019.

Chimeric Antigen Receptor T-cell (CAR-T) therapy has revolutionized the field of hematologic malignancies and are potentially curative in patients with previously limited options. This review highlights key abstracts focusing on clinical studies in CAR-T therapy in leukemia and lymphoma presented at the 61 st annual meeting of the American Society of Hematology (December 2019, Orlando, FL). Selected studies discuss data on novel CAR-T constructs aimed at enhancing efficacy and durability of responses, improving toxicity mitigation strategies, challenging clinical scenarios in routine clinical practice for standard of care CAR-T therapy (role of bridging therapy, CNS involvement, and quality of life studies), and new technologies aiming to decrease production time to minimize delay in definitive therapy, all within the rapidly-evolving cellular immunotherapy landscape.

Use of Chimeric Antigen Receptor T Cell Therapy in Clinical Practice for Relapsed/Refractory Aggressive B Cell Non-Hodgkin Lymphoma: An Expert Panel Opinion from the American Society for Transplantation and Cellular Therapy.

Axicabtagene ciloleucel (YESCARTA; Kite Pharma, a Gilead Company, Los Angeles CA) and tisagenlecleucel (KYMRIAH; Novartis Pharmaceuticals Corp., Basel, Switzerland) are two CD19-directed chimeric antigen receptor (CAR) T cell products currently approved by the US Food and Drug Administration; the European Medicines Agency; Health Canada; Ministry of Health, Labor and Welfare (Japan); and Therapeutic Goods Administration (Australia) for treatment of specific subtypes of relapsed/refractory aggressive B cell non-Hodgkin lymphoma (NHL). Although this approval has been transformative in the use of cellular immunotherapy in lymphoma, there are concerns regarding appropriate use of this novel therapy and of short- and long-term toxicities. To address these issues, representatives of the American Society of Transplantation and Cellular Therapy convened to recognize and address key issues surrounding the clinical application of CD19 CAR T cell therapy in B cell lymphomas, in collaboration with worldwide experts. The aim of this article is to provide consensus opinion from experts in the fields of hematopoietic cell transplantation, cellular immunotherapy, and lymphoma regarding key clinical questions pertinent to the use of CD19 CAR T cell products for the treatment of NHL. As the clinical practice using CAR T cells grows worldwide, we anticipate that this guidance will be relevant for hematology/oncology physicians who care for patients with lymphomas.

Clinical utilization of Chimeric Antigen Receptor T-cells (CAR-T) in B-cell acute lymphoblastic leukemia (ALL)-an expert opinion from the European Society for Blood and Marrow Transplantation (EBMT) and the American Society for Blood and Marrow Transplantation (ASBMT).

On August 30, 2017, the U.S. Food and Drug Administration (US-FDA) approved tisagenlecleucel (KYMRIAH, Novartis, Basel, Switzerland), a synthetic bioimmune product of anti-CD19 chimeric antigen receptor-T cells (CAR-T), for the treatment of children and young adults with relapsed/refractory B-cell acute lymphoblastic leukemia (B-ALL). With this new era of personalized cancer immunotherapy, multiple challenges are present ranging from implementation of a CAR-T program to safe delivery of the drug, long-term toxicity monitoring and disease assessments. To address these issues, experts representing the American Society for Blood and Marrow Transplant (ASBMT), the European Group for Blood and Marrow Transplantation (EBMT), the International Society of Cell and Gene Therapy (ISCT), and the Foundation for the Accreditation of Cellular Therapy (FACT), formed a global CAR-T task force to identify and address key questions pertinent for hematologists and transplant physicians regarding the clinical use of anti CD19 CAR-T therapy in patients with B-ALL. This article presents an initial roadmap for navigating common clinical practice scenarios that will become more prevalent now that the first commercially available CAR-T product for B-ALL has been approved.

Preoperative Anemia: Evaluation and Treatment.

Previously undiagnosed anemia is often identified during routine assessment of surgical patients. Although studies suggest that perioperative anemia is associated with worse outcomes and a strong predictor for postoperative red cell transfusions, anemia is frequently ignored. Preoperative optimization of patients undergoing elective surgical procedures associated with significant blood loss, along with strategies to minimize intraoperative blood loss, shows promise for reducing postoperative transfusions and improving outcomes. In most situations, anemia can be corrected prior to elective surgeries and interventions. Future research should assess the timing and methods of optimization of preoperative anemia in surgery and which patients are best candidates for therapy.

A Clinical Prediction Model to Assess Risk for Chemotherapy-Related Hospitalization in Patients Initiating Palliative Chemotherapy.

IMPORTANCE: Chemotherapy-related hospitalizations in patients with advanced cancer are common, distressing, and costly. Methods to identify patients at high risk of chemotherapy toxic effects will permit development of targeted strategies to prevent chemotherapy-related hospitalizations. OBJECTIVE: To demonstrate the feasibility of using readily available clinical data to assess patient-specific risk of chemotherapy-related hospitalization. DESIGN, SETTING, AND PARTICIPANTS: Nested case-control study conducted from January 2003 through December 2011 at the Mass General/North Shore Cancer Center, a community-based cancer center in northeastern Massachusetts. The parent cohort included 1579 consecutive patients with advanced solid-tumor cancer receiving palliative-intent chemotherapy. Case patients (n = 146) included all patients from the parent cohort who experienced a chemotherapy-related hospitalization. Controls (n = 292) were randomly selected from 1433 patients who did not experience a chemotherapy-related hospitalization. EXPOSURES: Putative risk factors for chemotherapy-related hospitalization-including patient characteristics, treatment characteristics, and pretreatment laboratory values-were abstracted from medical records. Multivariable logistic regression was used to model the patient-specific risk of chemotherapy-related hospitalization. MAIN OUTCOMES AND MEASURES: Chemotherapy-related hospitalization, as adjudicated by the oncology clinical care team within a systematic quality-assessment program. RESULTS: A total of 146 (9.2%) of 1579 patients from the parent cohort experienced a chemotherapy-related hospitalization. In multivariate regression, 7 variables were significantly associated with chemotherapy-related hospitalization: age, Charlson comorbidity score, creatinine clearance, calcium level, below-normal white blood cell and/or platelet count, polychemotherapy (vs monotherapy), and receipt of camptothecin chemotherapy. The median predicted risk of chemotherapy-related hospitalization was 6.0% (interquartile range [IQR], 3.6%-11.4%) in control patients and 14.7% (IQR, 6.8%-22.5%) in case patients. The bootstrap-adjusted C statistic was 0.71 (95% CI, 0.66-0.75). At a risk threshold of 15%, the model exhibited a sensitivity of 49% (95% CI, 41%-57%) and a specificity of 85% (95% CI, 81%-89%) for predicting chemotherapy-related hospitalization. CONCLUSIONS AND RELEVANCE: In patients initiating palliative chemotherapy for cancer, readily available clinical data were associated with the patient-specific risk of chemotherapy-related hospitalization. External validation and evaluation in the context of a clinical decision support tool are warranted.
