Abstract
PURPOSE To investigate the prognostic utility of the cachexia index (CXI) in unresectable advanced gastric cancer (UAGC). METHODS The relationship between CXI and the outcomes was evaluated in 102 patients with UAGC who had received first-line palliative 5-fluorouracil-based chemotherapy between January 2012 and December 2021. RESULTS The median survival time (MST) from first-line chemotherapy initiation was 16.2 months, and the cohort included 60 and 42 patients with high and low CXIs, respectively, based on the optimal CXI cutoff. The rates of patients with a performance status score of 0, recurrence, third-line chemotherapy, and all grade 3-4 side effects, including febrile neutropenia (FN), were significantly higher in the CXIhigh group than in the CXIlow group. The prognosis based on MST was significantly better in the CXIhigh group than in the CXIlow group (22.5 vs. 11.6 months, p < 0.001). According to a multivariate analysis, a low CXI and performance status score of 1-2 were poor prognostic factors. CONCLUSIONS Patients with UAGC and a low CXI had poorer prognoses and more frequent grade 3-4 side effects, including FN, than those with a high CXI. Patients with UAGC and a low CXI should be carefully managed to control for side effects to receive subsequent treatment.

Abstract
OBJECTIVES Development and validation of a predictive model including serum vitamin concentration to estimate the risk of chemotherapy-induced grade 3/4 neutropenia in esophageal cancer, gastric cancer, or colorectal cancer patients who receive the first cycle of chemotherapy. METHODS Data from 535 patients treated at the Affiliated Fuyang People's Hospital of Anhui Medical University from January 1, 2020, to March 2, 2022, were used to derive the predictive model. Least absolute shrinkage and selection operator regression analysis was performed to screen potential risk characteristics, and multivariate logistic regression was utilized to investigate efficient factors associated with chemotherapy-induced neutropenia. A nomogram was constructed using this logistic model. This nomogram was then tested on a temporal validation cohort containing 212 consecutive patients. RESULTS In the cohort of all 747 eligible patients, grade 3/4 neutropenia incidence was 45.2%. Age, Eastern Cooperative Oncology Group-performance status, neutrophil count, serum albumin, and hemoglobin data were entered into the final model. The performance of the final predictive nomogram was assessed by the area under the receiver operating characteristic curve in both the development and validation datasets. The calibration curves indicated that the estimated risks were accurate. Decision curve analysis for the predictive model exhibited improved clinical practicality. CONCLUSION In the present study, we established an accessible risk predictive model and identified valuable serum vitamin concentration parameters associated with chemotherapy-induced neutropenia. The predictive model may improve the grade 3/4 neutropenia risk prediction in patients with gastrointestinal malignancies who receive oxaliplatin- and fluoropyrimidine-based chemotherapy and help physicians make appropriate decisions for disease management.

Abstract
AIMS Large blood volumes are irradiated when the heart is exposed to radiation. The mean heart dose (MHD) may be a good surrogate for circulating lymphocytes exposure. We investigated the association between MHD and radiation-induced lymphopenia and explored the impact of the end-of-radiation-therapy (EoRT) lymphocyte count on clinical outcomes. MATERIALS AND METHODS In total, 915 patients were analysed: 303 patients with breast cancer and 612 with intrathoracic tumours: oesophageal cancer (291), non-small cell lung cancer (265) and small cell lung cancer (56). Heart contours were generated using an interactive deep learning delineation process and an individual dose volume histogram for each heart was obtained. A dose volume histogram for the body was extracted from the clinical systems. We compared different models analysing the effect of heart dosimetry on the EoRT lymphocyte count using multivariable linear regression and assessed goodness of fit. We published interactive nomograms for the best models. The association of the degree of EoRT lymphopenia with clinical outcomes (overall survival, cancer treatment failure and infection) was investigated. RESULTS An increasing low dose bath to the body and MHD were associated with a low EoRT lymphocyte count. The best models for intrathoracic tumours included dosimetric parameters, age, gender, number of fractions, concomitant chemotherapy and pre-treatment lymphocyte count. Models for patients with breast cancer showed no improvement when adding dosimetric variables to the clinical predictors. EoRT lymphopenia grade ≥3 was associated with decreased survival and increased risk of infections among patients with intrathoracic tumours. CONCLUSION Among patients with intrathoracic tumours, radiation exposure to the heart contributes to lymphopenia and low levels of peripheral lymphocytes after radiotherapy are associated with worse clinical outcomes.

Abstract
BackgroundA tool for estimating risk of febrile neutropenia (FN) after chemotherapy, namely the FEbrile Neutropenia after ChEmotherapy (FENCE) score, has been developed but has not been widely validated. This study aimed to validate the FENCE score as a tool for predicting granulocyte colony-stimulating factor (G-CSF) breakthrough FN among patients with lymphoma who underwent chemotherapy.MethodsThis was a prospective observational study of treatment-naive adult patients with lymphoma who underwent their first cycle of chemotherapy between 2020 and 2021. The patients were followed up until the next cycle of chemotherapy to identify any infection events.ResultsAmong the 135 patients with lymphoma, 62 (50%) were men. In a comparison of the value of each FENCE parameter for predicting G-CSF breakthrough infection, the parameter of advanced-stage disease showed high sensitivity of 92.8%, and receipt of platinum chemotherapy showed high specificity of 95.33%. With a FENCE score of 12 as a cutoff for low risk, analysis across all patients with lymphoma resulted in a high AUROCC of 0.63 (95% CI = 0.5–0.74%; p = 0.059), and analysis across only patients with diffuse large B-cell lymphoma (DLBCL) resulted in an AUROCC of 0.65 (95% CI = 0.51–0.79%; p = 0.046). With a cutoff point of 12, FENCE score can predict breakthrough infection events at 30.0% (95% CI = 17.8–47.4%).ConclusionThis study divided patients with lymphoma into risk groups according to FENCE score, showing that this instrument has discriminatory ability in predicting FN events, these being more likely to occur in patients in the intermediate- and high-risk groups. Multicenter studies are needed to validate this clinical risk score.

Development of a Machine Learning-Based Prediction Model for Chemotherapy-Induced Myelosuppression in Children with Wilms' Tumor. Cancers (Basel) 2023; 15:cancers15041078. [PMID: 36831423 PMCID: PMC9954251 DOI: 10.3390/cancers15041078] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/13/2023] [Revised: 02/03/2023] [Accepted: 02/05/2023] [Indexed: 02/11/2023] Open
Abstract
Purpose: Develop and validate an accessible prediction model using machine learning (ML) to predict the risk of chemotherapy-induced myelosuppression (CIM) in children with Wilms' tumor (WT) before chemotherapy is administered, enabling early preventive management. Methods: A total of 1433 chemotherapy cycles in 437 children with WT who received chemotherapy in our hospital from January 2009 to March 2022 were retrospectively analyzed. Demographic data, clinicopathological characteristics, hematology and blood biochemistry baseline results, and medication information were collected. Six ML algorithms were used to construct prediction models, and the predictive efficacy of these models was evaluated to select the best model to predict the risk of grade ≥ 2 CIM in children with WT. A series of methods, such as the area under the receiver operating characteristic curve (AUROC), the calibration curve, and the decision curve analysis (DCA) were used to test the model's accuracy, discrimination, and clinical practicability. Results: Grade ≥ 2 CIM occurred in 58.5% (839/1433) of chemotherapy cycles. Based on the results of the training and validation cohorts, we finally identified that the extreme gradient boosting (XGB) model has the best predictive efficiency and stability, with an AUROC of up to 0.981 in the training set and up to 0.896 in the test set. In addition, the calibration curve and the DCA showed that the XGB model had the best discrimination and clinical practicability. The variables were ranked according to the feature importance, and the five variables contributing the most to the model were hemoglobin (Hgb), white blood cell count (WBC), alkaline phosphatase, coadministration of highly toxic chemotherapy drugs, and albumin. Conclusions: The incidence of grade ≥ 2 CIM was not low in children with WT, which needs attention. The XGB model was developed to predict the risk of grade ≥ 2 CIM in children with WT for the first time. The model has good predictive performance and stability and has the potential to be translated into clinical applications. Based on this modeling and application approach, the extension of CIM prediction models to other pediatric malignancies could be expected.

Abstract
BACKGROUND Cancer treatments suppress immune function and are associated with increased risk of infections, but the overall burden of serious infectious diseases in treated patients has not been clearly elucidated. METHODS All patients treated for solid malignant tumours with radiotherapy (RT) and/or standard first-line chemotherapy (C) at the Department of Oncology at Rigshospitalet between 01/1/2010 and 31/12/2016 were included. Patients were followed from treatment initiation until the first of new cancer treatment, 1 year after treatment initiation, end of follow-up or death. Incidence rates (IR) of positive blood culture (PBC) per 1000 person-years follow-up (PYFU) were calculated. FINDINGS 12,433 individuals were included, 3582 (29%), 6349 (51%), and 2502 (20%) treated with RT, C, or both RT & C, respectively, contributing 8182 PYFU. 429 (3%) individuals experienced 502 unique episodes of PBC, incidence rate (95% CI) 52.43 (47.7, 57.6) per 1000 PYFU. The 30-day mortality rate after PBC was 24% independent of treatment modality. Adjusted incidence rate ratios in the first 3 months (95% CI) after PBC significantly varied by treatment: 2.89 (1.83, 4.55) and 2.52 (1.53, 4.14) for C and RT & C compared to RT. Escherichia coli (n = 127, 25%) was the top microorganism identified. INTERPRETATION PBCs are not common, but when they occur, mortality is high.

Abstract
PURPOSE Docetaxel + cisplatin + 5-fluorouracil (DCF) therapy, a frequently prescribed regimen for esophageal cancer, is associated with a high risk of febrile neutropenia (FN). This study investigated whether a low skeletal muscle mass index (SMI) is an independent risk factor for FN. METHODS This retrospective, observational study investigated the SMI of patients with esophageal cancer who received DCF therapy between March 2018 and July 2020. Based on the Asian sarcopenia criteria, patients were divided into two groups: high and low SMI (SMI of < 7.0 and 5.7 kg/m2 for males and females, respectively). The incidence of FN was then compared between the two groups. RESULTS Thirty-nine patients (20 and 19 in the high- and low-SMI groups, respectively) were included in this study. The incidence of FN was significantly higher in the low-SMI group (63.2% vs. 20.0%, P = 0.006). Univariable and multivariable logistic regression analyses revealed that a low SMI was an independent risk factor for FN (odds ratio, 7.178; 95% confidence interval, 1.272-40.507; P = 0.026). In addition, the frequency of dose reduction in DCF therapy was significantly higher in the low-SMI group (68.4% vs. 35.0%, P = 0.037). CONCLUSION Low SMI is an independent risk factor for FN in patients with esophageal cancer receiving DCF therapy.

Abstract
PURPOSE Though febrile neutropenia (FN) risk prediction models are important in clinical practice, their external validation is limited. In this study, we validated the Cycle-Specific Risk of FEbrile Neutropenia after ChEmotherapy (CSRFENCE) score for predicting FN. METHODS We reviewed the medical records of patients with solid malignancies and diffuse large B-cell lymphoma during chemotherapy cycles 2-6 and recorded if patients developed FN, defined as absolute neutrophil counts less than 500 cells/microL with fever more than or equal to 38.2 ℃. The CSRFENCE score was determined by adding the risk factors' coefficients described by the original study; subsequently, the score was used to classify chemotherapy cycles into the following risk groups for developing FN: low, intermediate, high, and very high risk. The discriminatory ability of the score was assessed using area under the receiver operating characteristics curve (AUROCC) and incidence rate ratios (IRR) within each CSRFENCE risk group. RESULTS We analyzed 2870 chemotherapy cycles, of which 42 (1.5%) were associated with FN. Among those, 3 (7.1%), 14 (33.3%), 5 (12%), and 20 (47.6%) were classified as low, intermediate, high, and very high risk for developing FN, respectively. The AUROCC was 0.72 (95% CI 0.64-0.81). Compared with the low risk group (n = 666), the IRR of developing FN was 1.01 (95% CI 0.15-43.37), 0.69 (95% CI 0.08-32.46) and 1.17 (95% CI 0.17-49.49) in the intermediate (n = 1431), high (n = 498) and very high (n = 275) risk groups, respectively. CONCLUSION The CSRFENCE model can moderately stratify patients into four risk groups for predicting FN prior to chemotherapy cycles 2-6.

Abstract
Background Febrile neutropenia (FN), owing to its negative association with immune function and infectious complications, acts as a treatment-limiting factor in myelotoxic cancer chemotherapy. This study aimed to analyze the incidence of FN, utilization of granulocyte colony-stimulating factor (G-CSF) in patients who experienced FN, and its association with age and comorbidities. Methodology This retrospective study was conducted in a major tertiary hospital in Riyadh, Kingdom of Saudi Arabia. Inclusion criteria entailed all neutropenic adults aged >18 years with a proven cancer diagnosis, including solid and hematological malignancies. Patients who were treated with chemotherapy and G-CSF were included in the study. Data regarding FN, administration of G-CSF, and patient and physician-related factors were collected. Results We collected data on 53 cancer patients with a mean age of 41.9 ± 17.1 years (range = 16-75). FN was present in 16 (30.2%) patients and absent in 37 (69.8%) patients. The mean neutrophil count post-filgrastim did not significantly differ from pre-chemotherapy neutrophil count (Student’s t-test, p = 0.067), while there was a significant difference from post-chemotherapy neutrophil count (Student’s t-test, p = 0.044). In our cohort, 24 (45.3%) patients achieved remission, 12 (22.6%) died, and 17 (32.1%) were not cured. We did not find any significant association between gender, specialty, comorbidities, and age with FN. Conclusions G-CSF administration significantly decreases the incidence of FN post-chemotherapy in cancer patients.

Abstract
Testicular germ cell tumors (GCTs) are the most common solid malignancy in males aged 15–35 years. Febrile neutropenia (FN) is a serious complication of chemotherapy that frequently occurs in patients with GCTs. The present retrospective study aimed to evaluate the effect of primary granulocyte-colony stimulating factor (G-CSF) prophylaxis on the incidence of FN in patients with GCTs. The present study included a review of the medical records of patients diagnosed with GCTs treated with first-line/adjuvant chemotherapy between January 2000 and December 2017 at the National Cancer Institute (Bratislava, Slovakia). In January 2006, a decision was made to administer G-CSF prophylaxis (filgrastim or pegfilgrastim) to patients after every cycle of chemotherapy. The present study included 385 patients, and out of these, 264 patients received primary G-CSF prophylaxis, while 121 patients did not. A total of 71 patients (18.4%) suffered from FN events. In the subgroup that did not receive primary prophylaxis, 42 patients exhibited FN, while only 29 patients with primary prophylaxis suffered from FN (34.7 vs. 11.0%; P=0.00000003). According to the subgroup analysis, FN incidence was decreased in all groups that received primary prophylaxis, except for patients with stage I GCT receiving adjuvant chemotherapy, without affecting overall survival. Primary G-CSF prophylaxis was associated with markedly reduced FN incidence in patients treated with first-line chemotherapy for metastatic disease. Therefore, the results of the present study suggested that primary G-CSF prophylaxis should be considered in patients with GCT receiving first-line chemotherapy.

Development and Validation of a Risk Score for Post-Transplant Lymphoproliferative Disorders among Solid Organ Transplant Recipients. Cancers (Basel) 2022; 14:cancers14133279. [PMID: 35805050 PMCID: PMC9265532 DOI: 10.3390/cancers14133279] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/16/2022] [Revised: 06/30/2022] [Accepted: 07/01/2022] [Indexed: 02/01/2023] Open
Abstract
Post-transplant lymphoproliferative disease (PTLD) is a well-recognized complication after transplant. This study aimed to develop and validate a risk score to predict PTLD among solid organ transplant (SOT) recipients. Poisson regression identified predictors of PTLD with the best fitting model selected for the risk score. The derivation cohort consisted of 2546 SOT recipients transpanted at Rigshospitalet, Copenhagen between 2004 and 2019; 57 developed PTLD. Predictors of PTLD were high-risk pre-transplant Epstein–Barr Virus (EBV), IgG donor/recipient serostatus, and current positive plasma EBV DNA, abnormal hemoglobin and C-reactive protein levels. Individuals in the high-risk group had almost 7 times higher incidence of PTLD (incidence rate ratio (IRR) 6.75; 95% CI: 4.00–11.41) compared to the low-risk group. In the validation cohort of 1611 SOT recipients from the University Hospital of Zürich, 24 developed PTLD. A similar 7 times higher risk of PTLD was observed in the high-risk group compared to the low-risk group (IRR 7.17, 95% CI: 3.05–16.82). The discriminatory ability was also similar in derivation (Harrell’s C-statistic of 0.82 95% CI (0.76–0.88) and validation (0.82, 95% CI:0.72–0.92) cohorts. The risk score had a good discriminatory ability in both cohorts and helped to identify patients with higher risk of developing PTLD.

Abstract
Febrile neutropenia (FN) is a common side effect of cytotoxic chemotherapy that may result in poor treatment outcomes. The short acting granulocyte colony stimulating factors (G-CSF) act to stimulate granulocytes to increase production of white blood cells. The filgrastim biosimilar is useful, as it may provide a cheaper and equally effective treatment to FN. This study explored the usage of the filgrastim biosimilar (Grastofil®) and the reference biologic (Neupogen®) in breast cancer and lymphoma patients. A retrospective chart review of patients receiving Grastofil® from January 2017 to June 2019 or Neupogen® for primary prophylaxis of FN from January 2013 to December 2017 was conducted. The endpoints included the incidence of FN and the occurrence of dose reduction (DR) and dose delay (DD). One hundred and fifty-three Grastofil® patients were matched to 153 Neupogen® patients. This cohort was further split into breast cancer (n = 275) and non-Hodgkin’s lymphoma (n = 31) cohorts. After adjusting for chemotherapy cycles, the biosimilar filgrastim was non-inferior to the reference biologic based on FN incidence in addition to related outcomes including DR and DD.

Abstract
IMPORTANCE Prevention of chemotherapy-induced neutropenia (CIN) and its clinical consequences is an unmet need for which plinabulin, a selective immunomodulating microtubule-binding agent, is being tested. OBJECTIVE To demonstrate noninferiority between plinabulin and pegfilgrastim for days of severe neutropenia in cycle 1 in patients with solid tumors treated with docetaxel. DESIGN, SETTING, AND PARTICIPANTS The Plinabulin vs Pegfilgrastim for the Prevention of Docetaxel-Induced Neutropenia in Patients With Solid Tumors (PROTECTIVE-1) double-blind phase 3 randomized clinical trial was performed in multiple centers in China, Russia, Ukraine, and the US. Participants included patients with breast, prostate, or non-small cell lung cancer treated with single-agent docetaxel chemotherapy. Data were collected from June 1, 2018, to January 31, 2019. The database was locked on February 18, 2021. Data analysis was based on intention to treat and safety and performed from October 5, 2018, to February 23, 2021. INTERVENTIONS Plinabulin, 40 mg, plus placebo or pegfilgrastim, 6 mg, plus placebo. MAIN OUTCOMES AND MEASURES The primary end point was day of severe neutropenia in cycle 1. Additional end points included clinical consequences of CIN (febrile neutropenia, hospitalizations, infections, antibiotic use, and modifications of chemotherapy dose), patient-reported outcomes for bone pain score, markers for immune suppression (neutrophil-to-lymphocyte ratio [NLR] of >5), immature neutrophils (band, promyelocyte, and myelocyte counts >0), and safety. RESULTS Among the 105 patients included in the analysis (65 [6.19%] women; median age, 59 [range, 31-81] years), the primary end point was met within a noninferiority margin of 0.65 days, with a mean difference of 0.52 days (98.52% CI, 0.40-0.65 days). Grade 4 neutropenia frequency in cycle 1 was not significantly different. Plinabulin had earlier onset of action with less grade 4 neutropenia in week 1 of cycle 1. Plinabulin had fewer adverse clinical consequences with rates of febrile neutropenia (0 of 52 vs 1 of 53 [1.9%]), infections (4 of 52 [7.7%] vs 8 of 53 [15.1%]), chemotherapy dose delay of more than 7 days (2 of 52 [3.8%] vs 3 of 53 [5.7%]), and permanent chemotherapy discontinuation (7 of 52 [13.5%] vs 14 of 53 [26.4%]). Patients receiving plinabulin had significantly less bone pain (difference, -0.67 [95% CI, -1.17 to -0.16]; P = .01) and a better immunosuppressive profile (NLR >5 at day 8, 2 of 52 [3.8%] vs 24 of 51 [46.0%]; P < .001). Plinabulin was well tolerated, with comparable safety to pegfilgrastim. CONCLUSIONS AND RELEVANCE Plinabulin has comparable efficacy to pegfilgrastim for the prevention of CIN, with better safety and a better immunosuppressive profile. Plinabulin's same-day dosing compared with pegfilgrastim's next-day dosing offers distinct advantages, including reducing use of health care services.

Abstract
Infections represent a significant cause of morbidity and mortality in cancer patients. Multiple factors related to the patient, tumor, and cancer therapy can affect the risk of infection in patients with solid tumors. A thorough understanding of such factors can aid in the identification of patients with substantial risk of infection, allowing medical practitioners to tailor therapy and apply prophylactic measures to avoid serious complications. The use of novel treatment modalities, including targeted therapy and immunotherapy, brings diagnostic and therapeutic challenges into the management of infections in cancer patients. A growing body of evidence suggests that antibiotic therapy can modulate both toxicity and antitumor response induced by chemotherapy, radiotherapy, and especially immunotherapy. This article provides a comprehensive review of potential risk factors for infections and therapeutic approaches for the most prevalent infections in patients with solid tumors, and discusses the potential effect of antibiotic therapy on toxicity and efficacy of cancer therapy.

Abstract
BACKGROUND Fever in neutropenia (FN) remains a frequent complication in pediatric patients undergoing chemotherapy for cancer. Preventive strategies, like primary antibiotic prophylaxis, need to be evidence-based. PROCEDURE Data on pediatric patients with any malignancy from the prospective multicenter SPOG 2015 FN Definition Study (NCT02324231) were analyzed. A score predicting the risk to develop FN with safety-relevant events (SRE; bacteremia, severe sepsis, intensive care unit admission, death) was developed using multivariate mixed Poisson regression. Its predictive performance was assessed by internal cross-validation and compared with the performance of published rules. RESULTS In 238 patients, 318 FN episodes were recorded, including 53 (17%) with bacteremia and 68 (21%) with SRE. The risk-prediction score used three variables: chemotherapy intensity, defined according to the expected duration of severe neutropenia, time since diagnosis, and type of malignancy. Its cross-validated performance, assessed by the time needed to cover (TNC) one event, exceeded the performance of published rules. A clinically useful score threshold of ≥11 resulted in 2.3% time at risk and 4.1 months TNC. Using external information on efficacy and timing of intermittent antibiotic prophylaxis, 4.3 months of prophylaxis were needed to prevent one FN with bacteremia, and 5.2 months to prevent one FN with SRE, using a threshold of ≥11. CONCLUSIONS This score, based on three routinely accessible characteristics, accurately identifies pediatric patients at risk to develop FN with SRE during chemotherapy. The score can help to design clinical decision rules on targeted primary antibiotic prophylaxis and corresponding efficacy studies.

Abstract
INTRODUCTION This study was conducted to develop and validate a nomogram for predicting the risk of neutropenia or febrile neutropenia (FN) in tumor patients in the first cycle of etoposide-based chemotherapy. METHODS This retrospective cohort study used an information system to monitor patients with non-Hodgkin's lymphoma or solid tumors receiving an etoposide regimen in the first chemotherapy cycle in our hospital from 2009 to 2020. Binary logistic regression analysis was used to identify the influencing factors of patients with neutropenia or FN. Those factors were then used to develop a nomogram. RESULTS A total of 1,554 patients were divided into the development group (n = 1,072) and validation group (n = 482). Variables used to predict neutropenia or FN were Karnofsky performance status (odds ratio [OR] = 0.85, 95% confidence interval [CI] = 0.81-0.89, p < 0.01), metastatic sites ≥3 (OR = 6.33, 95% CI = 2.66-15.11, p < 0.01), comorbidity of heart disease (OR = 4.88, 95% CI = 1.74-13.67, p < 0.01), recent surgery (OR = 7.96, 95% CI = 1.96-32.36, p < 0.01), administration of alkylating agents (OR = 4.50, 95% CI = 1.10-18.48, p < 0.01), total bilirubin ≥25 μmol/L (OR = 11.42, 95% CI = 4.00-32.61, p < 0.01), and lymphocyte count <0.7 × 109/L (OR = 4.22, 95% CI = 2.00-9.75, p < 0.01). CONCLUSION This model can aid the early identification and screening of the potential risk of neutropenia or FN in the first cycle of treatment for patients using etoposide-based chemotherapy.

Abstract
BACKGROUND Radiation-based therapy is widely used for advanced cervical cancer. Prior radiation-based therapy is a potential risk factor for febrile neutropenia (FN). However, the effect of irradiation field size on the incidence of FN during recurrent cervical cancer treatment is unclear. This study aimed to investigate the relationship between prior irradiation field size and FN development during recurrent chemotherapy. METHODS This retrospective, observational study included cervical cancer patients who received recurrent chemotherapy between November 2006 and June 2020. The patients were classified into two groups based on the area of irradiation fields. The first group included patients with a history of whole pelvis (WP) irradiation (WP group). The second group had patients who underwent WP plus para-aortic lymph node (PAN) irradiation (WP + PAN group). The incidences of hematological toxicities and FN during the recurrent chemoradiotherapy were compared between the two groups. RESULTS The FN incidence was significantly higher in the WP + PAN group than in the WP group (32.1% vs. 0%, P < 0.001). The incidence of Grade 4 neutropenia was not significantly different between the WP + PAN and WP groups. The nadir absolute neutrophil counts were significantly lower and the dose reduction or discontinuation rate of chemotherapy was significantly higher in the WP + PAN group than in the WP group. CONCLUSION History of WP plus PAN radiation is a risk factor for developing FN during recurrent cervical cancer chemotherapy.

Abstract
Since the COVID-19 outbreak started, it has been affecting mainly older individuals. Among the most vulnerable older individuals are those with cancer. Many published guidelines and consensus papers deal with prioritizing cancer care. Given the lack of high-quality evidence for management of cancer in older patients also in normal times, it is even more stringent to provide some resources on how to avoid both undertreatment and overtreatment in this population, who as of now is twice challenged to death, due to both a greater risk of getting infected with COVID-19 as well as from cancer not adequately addressed and treated. We hereby discuss some general recommendations (implement triage procedures; perform geriatric assessment; carefully assess comorbidity; promote early integration of palliative care in oncology; acknowledge the role of caregivers; maintain active take in charge to avoid feeling of abandonment; mandate seasonal flu vaccination) and discuss practical suggestions for specific disease settings (early-stage and advanced-stage disease for solid tumors, and hematological malignancies). The manuscript provides resources on how to avoid both undertreatment and overtreatment in older patients with cancer, who as of now is twice challenged to death, due to both a greater risk of getting infected with COVID-19 as well as from cancer not adequately addressed and treated.

Abstract
Lung cancer, as the leading cause of death in oncology is one of the most challenging diseases nowadays. Even after the implementation of checkpoint inhibitors and targeted therapy as a standard of therapy for metastatic disease, the chemotherapy backbone remains essential in the treatment of these patients. This study aimed to evaluate how administration particularities in chemotherapy and toxicity management can influence the outcome. We conducted a retrospective single-institution study, at Elias University Emergency Hospital, Bucharest, Romania, between 2014 and 2018, in a heterogeneous patient population with metastatic non-small cell lung cancer that received combination chemotherapy. The inclusion criteria for this trial were—histological proof of non-small cell lung cancer (NSCLC), stage IV disease, ECOG (Eastern Cooperative Oncology Group) performance status of a maximum of two, treatment with cytotoxic chemotherapy for at least four courses (patients with fewer courses were excluded). All patients received combination chemotherapy. The main focus was on the effect of dose reduction and treatment delay on overall survival and progression-free survival. A total of 129 patients were enrolled. The response rate in the studied population was 69% and 62.8% had no toxicity greater than grade 2. Chemotherapy regimens used had the following distribution—paclitaxel + carboplatin 41.9%, paclitaxel + carboplatin + bevacizumab 12.4%, pemetrexed + carboplatin 12.4%, gemcitabine + carboplatin 26.4% and other regimens 7%. Mean PFS (Progression Free Survival) was 9.1 months and the mean OS (Overall Survival) was 14 months. OS was not significantly different in the treatment delay group versus the no delay one, p < 0.25 but dose- reduction significantly impacted OS, p < 0.03. Administration particularities, like febrile neutropenia prophylaxis, treatment of chemotherapy-related anemia, respecting the details of chemostability and preparation rules and emesis prophylaxis, were considered reasons for the good outcome. Details regarding cytotoxic chemotherapy administration remain of paramount importance for a good outcome and the benefit for survival they convey is crucial. Sometimes the benefit the patient derives from these details is comparable to the one newer therapies convey.

Front Oncol 2020; 10:692. [PMID: 32426291 PMCID: PMC7204396 DOI: 10.3389/fonc.2020.00692] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/12/2019] [Accepted: 04/14/2020] [Indexed: 11/17/2022] Open
Abstract
Purpose: The aim of this study is to evaluate the risk factors for ≥ grade 3 neutropenia in gastric cancer patients receiving postoperative adjuvant chemotherapy. Methods: This is a retrospective study from a single tertiary referral hospital. Patients diagnosed with gastric cancer who met the inclusion criteria were included in this study. Baseline and clinicopathological characteristics of the patients were collected. Patients were followed-up for 12 months and the incidence of neutropenia were recorded. Factors associated with neutropenia of chemotherapy in cycle 1 were investigated. Results: A total of 202 patients with gastric cancer were included. All patients received oxaliplatin plus oral capecitabine (CAPEOX) as the adjuvant chemotherapy. The incidence of ≥ grade 3 neutropenia is 11.9% (24/202) in cycle 1 among all patients. In multivariate analysis, independent risk factors for ≥ grade 3 neutropenia were serum prealbumin level (p = 0.041), prognostic nutritional index (PNI) (p = 0.049) and pre-cycle neutrophil count (p = 0.007). Conclusions: Our findings for the first time showed that nutritional parameter as prealbumin level and PNI are independent risk factors for neutropenia in gastric cancer patients receiving adjuvant chemotherapy. This may provide evidence for further investigation on prophylaxis use of granulocyte colony-stimulating factor in selected high-risk patients to prevent sever neutropenia in cycle 1 of adjuvant chemotherapy.

Mortality and admission to intensive care units after febrile neutropenia in patients with cancer. Cancer Med 2020; 9:3033-3042. [PMID: 32144897 PMCID: PMC7196064 DOI: 10.1002/cam4.2955] [Citation(s) in RCA: 20] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/23/2019] [Revised: 01/06/2020] [Accepted: 02/19/2020] [Indexed: 12/13/2022] Open
Abstract
Febrile neutropenia (FN) is a critical complication of chemotherapy associated with increased in‐hospital mortality. However, associations with increased mortality and intensive care unit (ICU) admissions during longer follow‐up are not established. Patients treated with standard first‐line chemotherapy for solid cancers at Rigshospitalet, Denmark in 2010‐2016 were included. Incidence rate ratios (IRR) of all‐cause, infectious and cardiovascular mortality, and ICU admissions after FN were analyzed by Poisson regression. Risk factors at the time of FN were analyzed in the subpopulation of patients with FN; all‐cause mortality was further stratified by the time periods 0‐30, 31‐365, and 366+ days after FN. We included 9018 patients with gastric (14.4%) and breast (13.1%) cancer being the most common, 51.2% had locally advanced or disseminated disease and the patients had a median Charlson Comorbidity Index score of 0 (interquartile range, 0‐0). During follow‐up, 845 (9.4%) experienced FN and 4483 (49.7%) died during 18 775 person‐years of follow‐up. After adjustment, FN was associated with increased risk of all‐cause mortality, infectious mortality, and ICU admissions with IRRs of 1.39 (95% CI, 1.24‐1.56), 1.94 (95% CI, 1.43‐2.62), and 2.28 (95% CI, 1.60‐3.24). Among those with FN, having a positive blood culture and low lymphocytes were associated with excess risk of death and ICU admissions (predominantly the first 30 days after FN), while elevated C‐reactive protein and low hemoglobin predicted mortality the first year after FN. The risk of death varied according to the time since FN; adjusted IRR per additional risk factor present for the time periods 0‐30, 31‐365, and 366+ days after FN were 2.00 (95% CI, 1.45‐2.75), 1.36 (95% CI, 1.17‐1.57), and 1.17 (95% CI, 0.98‐1.41). FN was associated with increased mortality and risk of ICU admissions. An objectively identifiable subgroup of patients among those with FN carried this excess risk.

Development and validation of a cycle-specific risk score for febrile neutropenia during chemotherapy cycles 2-6 in patients with solid cancers: The CSR FENCE score. Int J Cancer 2019; 146:321-328.

Abstract
The absolute risk reduction by prophylaxis in chemotherapy-induced febrile neutropenia (FN) is largest in patients at highest underlying risk. Therefore, reliable predictive models are needed. Here, we develop and validate such a model for risk of FN during chemotherapy cycles 2-6. A prediction score for risk of FN during the first cycle has recently been published. Patients with solid cancers initiating first-line chemotherapy in 2010-2016 were included. Cycle-specific risk factors were assessed by Poisson regression using generalized estimating equations and random split sampling. The derivation cohort included 4,590 patients treated with 15,419 cycles, wherein 326 (2.1%) FN events occurred. Predictors of FN in multivariable analyses were: higher predicted risk of FN in the first cycle, platinum- or taxane-containing therapies, concurrent radiotherapy, treatment in cycle 2 compared to later cycles, previous FN or neutropenia and not receiving granulocyte colony-stimulating factors. Each predictor added between -2 and 8 points to each patient's score (median score 4; interquartile range, 1-6). The incidence rate ratios for developing FN in the intermediate (score 1-4), high (score 5-6) and very high risk groups (score ≥7) were 7.8 (95% CI, 2.4-24.9), 18.6 (95% CI, 5.9-58.8) and 51.7 (95% CI, 16.5-162.3) compared to the low risk group (score ≤0), respectively. The score had good discriminatory ability with a Harrell's C-statistic of 0.78 (95% CI, 0.76-0.80) in the derivation and 0.75 (95% CI, 0.72-0.78) in the validation cohort (patient n = 2,295, cycle n = 7,670). The Cycle-Specific Risk of FEbrile Neutropenia after ChEmotherapy score is the first published method to estimate cycle-specific risk of FN.

Abstract
Background Febrile neutropenia (FN) is a common complication to chemotherapy, associated with increased short-term morbidity and mortality. However, the long-term outcomes after FN are poorly elucidated. We examined the long-term risk of infection and mortality rates in cancer patients with and without FN. Methods Patients aged >16 years treated with firstline chemotherapy were followed from 180 days after initiating chemotherapy until first infection, a new treatment with chemotherapy, death, or end of follow-up. Risk factors for infections were analyzed by competing risks regression, with death or another treatment with chemotherapy as competing events. Adjusted incidence rate ratios (aIRRs) of infection and death were analyzed using Poisson regression. In analyses of mortality, infection was included as a time-updated variable. Results We included 7190 patients with a median follow-up (interquartile range) of 0.58 (0.20–1.71) year. A total of 1370 patients had an infection during follow-up. The aIRRs of infection were 1.86 (95% confidence interval [CI], 1.56–2.22) and 2.19 (95% CI, 1.54–3.11) for patients with 1 or >1 episode of FN compared with those without FN. Mortality rate ratios were 7.52 (95% CI, 6.67–8.48) <1 month after, 4.24 (95% CI, 3.80–4.75) 1–3 months after, 2.33 (95% CI, 1.63–3.35) 3–6 months after, and 1.09 (95% CI, 0.93–1.29) >6 months after an infection, compared with the time before infection. Conclusions FN during chemotherapy is associated with a long-term increased risk of infection. Mortality rates are substantially increased for 6 months following an infection.
