Accuracy of the Multinational Association of Supportive Care in Cancer (MASCC) and Clinical Index of Stable Febrile Neutropenia (CISNE) scores for predicting serious complications in adult patients with febrile neutropenia: A systematic review and meta-analysis

Nomogram for predicting neutropenia in patients with esophageal, gastric, or colorectal cancer treated by chemotherapy in the first cycle

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.

Evaluation of Febrile Neutropenia in Hospitalized Patients with Neoplasia Undergoing Chemotherapy

Febrile neutropenia (FN) is a common but serious complication encountered in patients with cancer and is associated with significant morbidity and mortality. In this prospective study, 63 patients with solid tumors under chemotherapy or immunotherapy were admitted to the hospital due to febrile neutropenia, confirmed through clinical or microbiological documentation. The aim of this study was to provide a comprehensive overview of the epidemiological and microbiological characteristics of hospitalized neutropenic patients with solid tumors undergoing treatment. Additionally, we aimed to assess the duration of neutropenia and identify factors influencing patient outcomes. The median age of patients was 71 ± 10.2 years, most of which were males (66.7%), and the primitive tumor location was the lung (38.1%), with most patients (82.5%) being at disease stage IV. The median duration of neutropenia was three days (range 1-10), and, notably, mucositis was significantly associated with neutropenia lasting ≥3 days (p = 0.012). Patients with lung cancer (38.1%) and patients with stage IV disease (82.5%) presented a higher risk of FN, although these differences did not reach statistical significance. The site of infection was identifiable in 55.6% of patients, with positive cultures detected in 34.9% and positive blood cultures (BC) drawn in 17.5% of cases. Gram-positive bacteria were the predominant causative agents in BC (63.6%), with Staphylococci being the most prevalent among them (66.7%). The median duration of hospitalization was nine days (range, 3-43 days), and most patients showed improvement or cure of infection (16.9% and 74.6%, respectively). Among recorded risk factors, the Eastern Cooperative Oncology Group (ECOG) performance status (PS) appears to be statistically significant. Patients with an impaired PS score (2-4) experienced worse outcomes and higher likelihood of mortality (p = 0.004). Regarding the outcome, a longer duration of neutropenia was also statistically significant (p = 0.050). Of the patients, 12.7% ultimately succumbed to their conditions, with 37.5% attributed to infections. FN is a common yet serious complication in solid tumor patients. Adequate knowledge of the predictors of mortality and the microbiological causes are of utmost importance to allow accurate diagnosis and prompt treatment as they significantly influence patient outcomes.

The reliability of FEbrile Neutropenia after ChEmotherapy (FENCE) scores in predicting granulocyte colony-stimulating factor breakthrough febrile neutropenia among patients with lymphoma undergoing first-cycle chemotherapy: A prospective observational study

Background

A 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.

Methods

This 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.

Results

Among 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%).

Conclusion

This 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.

Epidemiology and source of infection in cancer patients with febrile neutropenia: an experience from a developing country

BACKGROUND

Febrile neutropenia (FN) is a life-threatening complication that predisposes cancer patients to serious infections. This study aims to describe the epidemiology and source of infection in cancer patients with FN in a tertiary care hospital.

METHODS

A hospital-based retrospective study was conducted in a large tertiary care hospital from January 2020 to December 2021. Data on cancer patients with FN were collected from the hospital information system.

RESULTS

150 cancer patients with FN were identified during the study period. Most patients were males (98; 65.3%), and the mean age of participants was 42.2 ± 16.0 years. Most patients (127; 84.7%) had hematologic malignancies, and acute myeloid leukemia was the most common diagnosis (42; 28%), followed by acute lymphocytic leukemia (28; 18.7%) and Hodgkin's lymphoma (20; 13.3%). Fifty-four (36%) patients had a median Multinational Association for Supportive Care in Cancer (MASCC) scores greater than 21. Regarding the outcome, nine (6%) died, and 141(94%) were discharged. The focus of fever was unknown in most patients (108; 72%). Among the known origins of fever were colitis (12; 8%), pneumonia (8; 5.3%), cellulitis (6; 4%), bloodstream infections (7; 4.6%), perianal abscess (2; 1.3%) and others. The median duration of fever was two days, and the median duration of neutropenia was seven days. Sixty-three (42%) patients had infections: 56 (73.3%) were bacterial, four (2.6%) were viral, two (1%) were fungal and 1 (0.7%) was parasitic. Among the bacterial causes, 50 cases (89.2%) were culture-positive. Among the culture-positive cases, 34 (68%) were gram-positive and 22 (44%) were gram-negative. The most frequent gram-positive bacteria were E. faecalis (9; 18% of culture-positive cases), and the most frequent gram-negative organisms were Klebsiella pneumoniae (5; 10%). Levofloxacin was the most commonly used prophylactic antibiotic (23; 15.33%), followed by acyclovir (1610.7%) and fluconazole in 15 patients (10%). Amikacin was the most popular empiric therapy, followed by piperacillin/tazobactam (74; 49.3%), ceftazidime (70; 46.7%), and vancomycin (63; 42%). One-third of E. faecalis isolates were resistant to ampicillin. Approximately two-thirds of Klebsiella pneumoniae isolates were resistant to piperacillin/tazobactam and ceftazidime. Amikacin resistance was proven in 20% of isolates.

CONCLUSIONS

The majority of patients suffered from hematologic malignancies. Less than half of the patients had infections, and the majority were bacterial. Gram-positive bacteria comprised two-thirds of cases. Therefore, empiric therapy was appropriate and in accordance with the antibiogram of the isolated bacteria.

Clinical factors predicting return emergency department visits in chemotherapy-induced febrile neutropenia patients

BACKGROUND

Although chemotherapy-induced febrile neutropenia (FN) is the most common and life-threatening oncologic emergency, the characteristics and outcomes associated with return visits to the emergency department (ED) in these patients are uncertain. Hence, we aimed to investigate the predictive factors and clinical outcomes of chemotherapy-induced FN patients returning to the ED.

METHOD

This single-center, retrospective observational study spanning 14 years included chemotherapy-induced FN patients who visited the ED and were discharged. The primary outcome was a return visit to the ED within five days. We conducted logistic regression analyses to evaluate the factors influencing ED return visit.

RESULTS

This study included 1318 FN patients, 154 (12.1%) of whom revisited the ED within five days. Patients (53.3%) revisited the ED owing to persistent fever (56.5%), with no intensive care unit admission and only one mortality case who was discharged hopelessly. Multivariable analysis revealed that shock index >0.9 (odds ratio [OR]: 1.45, 95% confidence interval [CI], 1.01-2.10), thrombocytopenia (<100 × 10³/uL) (OR: 1.64, 95% CI, 1.11-2.42), and lactic acid level > 2 mmol/L (OR: 1.51, 95% CI, 0.99-2.25) were associated with an increased risk of a return visit to the ED, whereas being transferred into the ED from other hospitals (OR: 0.08; 95% CI, 0.005-0.38) was associated with a decreased risk of a return visit to the ED.

CONCLUSION

High shock index, lactic acid, thrombocytopenia, and ED arrival type can predict return visits to the ED in chemotherapy-induced FN patients.

Can Risk Stratification Tools Be Utilized to Safely Discharge Low-Risk Febrile Neutropenic Patients from the Emergency Department?

BACKGROUND

Chemotherapy-induced febrile neutropenia (FN) is one of the more common oncological emergencies. Despite evidence in the oncology literature suggesting that low-risk cases of FN can be managed safely at home, most patients with FN who present to the emergency department (ED) are admitted. FN risk stratification methods, such as Multinational Association for Supportive Care in Cancer (MASCC) and Clinical Index of Stable Febrile Neutropenia (CISNE) scores, may be useful when considering patient disposition. We sought to address whether the existing body of literature is adequate to support the use of these methods when treating patients with FN in the ED.

METHODS

A PubMed search from January 1, 2016 to March 19, 2021 was performed using the following search strategy: "febrile neutropenia" OR (fever AND neutropenia)) AND (emerg* OR outpatient) AND (admit OR admission OR hospitalization). General review articles and case reports were omitted. Each of the articles selected underwent a structured review.

RESULTS

The search yielded 371 articles, which were independently screened for relevance by two authors, and 23 articles were selected for inclusion. MASCC score was used in 10 of the identified studies and each of these studies concluded that the score was useful in the ED. Most of the identified studies found that CISNE score had a higher sensitivity than MASCC score (96.7% vs. 32.9%, respectively), but a lower specificity (22.2% vs. 89.5%).

CONCLUSIONS

FN risk stratifications tools, such as MASCC and CISNE scores, are supported by the existing literature and may be included as part of the decision-making process when considering patient disposition.

Procalcitonin as a Predictive Tool for Death and ICU Admission among Febrile Neutropenic Patients Visiting the Emergency Department

Background and Objectives: Risk stratification tools for febrile neutropenia exist but are infrequently utilized by emergency physicians. Procalcitonin may provide emergency physicians with a more objective tool to identify patients at risk of decompensation. Materials and Methods: We conducted a retrospective cohort study evaluating the use of procalcitonin in cases of febrile neutropenia among adult patients presenting to the Emergency Department compared to a non-neutropenic, febrile control group. Our primary outcome measure was in-hospital mortality with a secondary outcome of ICU admission. Results: Among febrile neutropenic patients, a positive initial procalcitonin value was associated with significantly increased odds of inpatient mortality after adjusting for age, sex, race, and ethnicity (AOR 9.912, p < 0.001), which was similar, though greater than, our non-neutropenic cohort (AOR 2.18, p < 0.001). All febrile neutropenic patients with a positive procalcitonin were admitted to the ICU. Procalcitonin had a higher sensitivity and negative predictive value (NPV) in regard to mortality and ICU admission for our neutropenic group versus our non-neutropenic control. Conclusions: Procalcitonin appears to be a valuable tool when attempting to risk stratify patients with febrile neutropenia presenting to the emergency department. Procalcitonin performed better in the prediction of death and ICU admission among patients with febrile neutropenia than a similar febrile, non-neutropenic control group.

Comprehensive evaluation of risk factors for the development and complications of chemotherapy-induced febrile neutropenia

Febrile neutropenia is a serious adverse effect of chemotherapy. It can lead to complications and death, as well as delays in treatment, chemotherapy dose reductions, compromised treatment efficacy, and reduced survival. The assessment of the patient-related risk factors plays a significant role in the prevention of febrile neutropenia and its complications. In the case of intermediate-risk chemotherapy, the patient-related factors contribute to the estimation of an overall febrile neutropenia risk as well as to timely planning of primary prophylaxis using growth factors. Patients presenting with febrile neutropenia undergo a detailed initial risk assessment for serious complications so that an appropriate treatment can be selected. Recommendations given by the guidelines outline the classification of and risk factors for febrile neutropenia complications. The use of patient-related factors and validated tools for the risk assessment of complications makes it possible to optimize the treatment for each patient and to reduce the risk of morbidity and mortality due to febrile neutropenia.

Evaluating the Prognostic Role of Monocytopenia in Chemotherapy-Induced Febrile Neutropenia Patients Treated with Granulocyte Colony-Stimulating Factor

Objective

Chemotherapy-induced febrile neutropenia is a common and serious oncological emergency which carries a substantial mortality and morbidity. The main objective of this study is to evaluate the usage of absolute monocyte count (AMC) at presentation as a prognostic factor for patients with chemotherapy-induced febrile neutropenia who were subsequently treated with granulocyte colony-stimulating factor (G-CSF).

Study Design

The electronic medical records of our center were used retrospectively to identify patients diagnosed with unprecedented chemotherapy-induced febrile neutropenia treated with G-CSF between January 2010 to December 2020 and diagnosed with solid and hematological malignancies. Patient’s demographics, disease characteristics and laboratory investigations were extracted. Disease progression measures were statistically compared between the study groups in the short-term period of follow-up (six days) including absolute neutrophil count (ANC), ANC difference compared to the baseline readings, hospitalization period, and mortality.

Results

A total of 80 patients were identified and categorized into two groups namely monocytopenia (n = 34) and non-monocytopenia (n = 46) with an AMC cutoff point of 0.1×10⁹ cells/L. The monocytopenia group exhibited a worse prognosis with lower ANC values and slower improvement illustrated by the low ANC difference values at all follow up points (P-value ≤ 0.05) apart from day 5. A statistically significant lower hospitalization period was also observed in the non-monocytopenia group (P-value = 0.006). Linear regression analysis evaluated the association between AMC values at admission and ANC values at admission along with subsequent days of follow up which were found to be statistically significant (P-value ≤ 0.05). Receiver operating characteristic curves suggest a satisfactory predictability of ANC changes by AMC values at admission, days1, 2, 3, 4 and 6.

Conclusion

Monocytopenia holds a worse prognosis in chemotherapy-induced febrile neutropenia patients treated with G-CSF. In addition, AMC values at presentation represents a potential risk factor that can predict short-term changes regarding ANC measures.

Evaluation of the clinical Index of Stable febrile neutropenia risk stratification system for management of febrile neutropenia in gynecologic oncology patients

OBJECTIVE

Scoring systems have been developed to identify low risk patients with febrile neutropenia (FN) who may be candidates for outpatient management. We sought to validate the predictive accuracy of the Clinical Index of Stable Febrile Neutropenia (CISNE) score alone and in conjunction with alternative scoring systems for risk of complications among gynecologic oncology patients.

METHODS

We conducted a single institution retrospective cohort study of patients admitted to an academic gynecologic oncology service for FN. We examined the performance characteristics (sensitivity, specificity, positive and negative predictive value) of three scoring systems (Multinational Association of Supportive Care in Cancer (MASCC), CISNE cut-off 1 (Low risk = 0), CISNE cut-off 2 (Low risk = <3)), and the combination of MASCC and CISNE to predict complications: inpatient death, ICU admission, hypotension, respiratory/renal failure, mental status change, cardiac failure, bleeding, and arrhythmia.

RESULTS

Fifty patients were identified for study inclusion. No low-risk CISNE patients died during hospitalization. Fewer CISNE low-risk patients experienced complications compared to high-risk patients, regardless of cut-off. Sensitivity, specificity, positive and negative predictive values of the scoring systems were: CISNE 1-37.1%, 86.7%, 86.7%, 37.1%; CISNE 2-85.7%, 46.7%, 78.9%, 58.3%; MASCC-82.9%, 66.7%, 85.3%, 62.5%; MASCC + CISNE 1-37.1%, 93.3%, 92.9%, 38.9%; MASCC + CISNE 2-80%, 73.3%, 87.5%, 61.1%.

CONCLUSIONS

The CISNE scoring system is an appropriate tool for the identification of patients with gynecologic cancers and FN who may benefit from close outpatient management. CISNE cut-off 2 performed comparably to the MASCC, but CISNE cut-off 1 had a higher specificity and positive predictive value.

The role of serum albumin/globulin ratio in combination with prognostic risk indexes of febrile neutropenia

OBJECTIVES

The aim of this study was to evaluate the effect of the serum albumin/globulin ratio (AGR) on the 30-day mortality of febrile neutropenia (FEN). The second aim of the study was to evaluate the effect of the combination of the AGR with the Multinational Association for Supportive Care in Cancer (MASCC) and Clinical Index of Stable Febrile Neutropenia (CISNE) risk indexes on 30-day mortality of FEN.

METHODS

A retrospective study evaluating the effect of serum AGR, MASCC and CISNE scores on 30-day FEN mortality.

RESULTS

A total of 137 FEN episodes in 120 patients were included in this study. Nineteen patients (14%) died within the first 30 days of FEN episodes. The 30-day mortality rate was calculated as 4% in patients with high AGR and 23% in patients with low AGR (P = .002). According to the MASCC and CISNE risk scores, the mortality rates in low-risk patients were 8% and 6%, respectively, and in the high-risk group 22% and 29%, respectively (P = .024 vs P < .001). In the group of patients with MASCC <21 and CISNE ≥3, the 30-day mortality rate was 7%, when the AGR was >1.13, and in those with AGR ≤1.13 mortality rate increased to 50% (P = .012).

CONCLUSION

A low AGR in a patient with FEN was found to be associated with an increased risk of 30-day mortality. Combining the AGR with MASCC and CISNE risk indexes might increase the predictive value of these scoring systems on 30-day mortality.

Effect of serum uric acid level and Multinational Association for Supportive Care in Cancer risk score on febrile neutropenia mortality

PURPOSE

The study was aimed to evaluate the effect of uric acid (UA) on the 30-day mortality of patients admitted to the tertiary referral hospital with a complaint of febrile neutropenia (FEN). The secondary aim was to evaluate the use of combining serum UA levels with the Multinational Association for Supportive Care in Cancer (MASCC) risk score.

METHODS

A retrospective study in which the MASCC score and serum UA levels were used to evaluate the mortality risk within 30 days among patients with FEN.

RESULTS

A total of 118 FEN episodes were included in the study and 17 (14%) of these patients died. While this rate is 23% in the high-risk group according to the MASCC score, it is 7% in the low-risk group (p = 0.011). In multivariate analysis of the parameters that significantly affect the 30-day FEN mortality, MASCC risk score (OR, 4.28; CI 95% 1.19-15.39, p = 0.013) and having a level of serum UA > 7 mg/dL (OR, 4.46; CI 95% 1.19-15.38, p = 0.032) was significantly increased the risk of in 30-day mortality of FEN. The rate of 30-day mortality of FEN was 0% in patients with a low MASCC risk score and UA level compared with 50% in the high MASCC risk score and high UA level group, and the difference was statistically significant (p < 0.001).

CONCLUSION

Increased level of UA at the time of FEN diagnosis was independently associated with an increased rate of 30-day mortality of FEN. The combination of the MASCC risk score and serum UA level might thoroughly predict the 30-day mortality of FEN.
