Chemotherapy Near the End of Life in Onco-Hematological Adult Patients

Sex-Based Analysis of Quality Indicators of End-of-Life Care in Gastrointestinal Malignancies

Indices of aggressive or supportive end-of-life (EOL) care are used to evaluate health services quality. Disparities according to sex were previously described, with studies showing that male sex is associated with aggressive EOL care. This is a secondary analysis of 69,983 patients who died of a GI malignancy in Ontario between 2006 and 2018. Quality indices from the last 14-30 days of life and aggregate measures for aggressive and supportive EOL care were derived from administrative data. Hospitalizations, emergency department use, intensive care unit admissions, and receipt of chemotherapy were considered indices of aggressive care, while physician house call and palliative home care were considered indices of supportive care. Overall, a smaller proportion of females experienced aggressive care at EOL (14.3% vs. 19.0%, standardized difference = 0.13, where ≥0.1 is a meaningful difference). Over time, rates of aggressive care were stable, while rates of supportive care increased for both sexes. Logistic regression showed that younger females (ages 18-39) had increased odds of experiencing aggressive EOL care (OR 1.71, 95% CI 1.30-2.25), but there was no such association for males. Quality of EOL care varies according to sex, with a smaller proportion of females experiencing aggressive EOL care.

Evaluation of factors predicting the benefit from systemic oncological treatment for severely ill hospitalized patients: a retrospective study

BACKGROUND

Patients with cancer in the disease's end-stage with poor performance represent a challenging clinical scenario, as they have high chance of a fatal outcome due to clinical conditions, oncological emergencies, and/or metastatic disease. This study examines the factors predicting the potential benefit of "urgent" chemotherapy during hospitalization in this setting, thus addressing a research gap.

METHODS

This retrospective observational study was conducted in the largest cancer center in the outskirts of São Paulo. It identified factors predicting the benefit from antineoplastic treatment in severe in-hospital patients admitted during 2019-2020, considering post-chemotherapy survival time as the main dependent variable. Data were retrieved from medical records. All patients aged ≥ 18 years, with an ECOG-PS score ≥ 2, and undergoing non-elective systemic cancer treatment were included.

RESULTS

This study evaluated 204 records, of which 89 were included in the final analysis. A statistically significant association with the worse outcome (death within 30 days of chemotherapy) was found with higher ECOG performance status; chemotherapy dose reduction; lower values of serum albumin, hemoglobin, and creatinine clearance; and higher values of leukocytes, neutrophils, direct bilirubin, urea, and C-reactive protein. In the multivariate analysis, only albumin remained statistically associated with the outcome (hazard ratio = 0.35; confidence interval: 0.14, 0.90; p = 0.034).

CONCLUSIONS

Serum albumin and other clinical and laboratory variables might be associated with early post-treatment deaths in patients with cancer. The study data might help guide the decision to administer systemic treatment in this scenario and manage critically ill patients. This study adds to our knowledge of the factors predicting the objective benefits from "heroic" or "urgent" chemotherapy for hospitalized and severely ill patients with cancer.

The prevalence of end-of-life chemotherapy and targeted therapy in Japan, assessed using a health claims database

PURPOSE

This study aimed to investigate the current status of end-of-life chemotherapy and targeted therapy and explore the aggressiveness of end-of-life care in Japan using the DeSC database, a large administrative claims database.

METHODS

We identified fatal cases of at least one cancer-related diagnosis between April 2015 and November 2020. Patients prescribed at least one anticancer drug were analyzed, and chemotherapy regimens were categorized based on the combination of concomitant anticancer drugs prescribed.

RESULTS

Among 1,095,713 individuals enrolled in the National Health Insurance database, 7,300 deaths with cancer-related diagnosis were identified. Of these, 4,010 cases were identified in which at least one anticancer drug was prescribed, and 11.6% of 7,300 death had been prescribed anticancer drugs in their last 30 days of life. The most commonly used regimen was S-1 (tegafur, gimeracil, and oteracil potassium combination) monotherapy, followed by nivolumab monotherapy and nab-paclitaxel plus gemcitabine. Immune checkpoint inhibitor monotherapy was more likely prescribed to patients whose last chemotherapy dose was in the last 30 days of life (p = 0.0066, chi-squared test).

CONCLUSIONS

This study provides insights into the current status of end-of-life chemotherapy and targeted therapy in Japan, using a large administrative claims database. The results of this study will inform future research on end-of-life chemotherapy and targeted therapy, and help develop strategies to improve the quality of life of patients with advanced cancer.

Evaluating aggressiveness of end-of-life care in patients with advanced cancer: A retrospective single-center analysis

INTRODUCTION

Overuse of anti-cancer therapy near end of life is an important quality-of-care issue. An aggressive approach to treatment can have negative effects on the quality of life and cost of hospital-based resources. The objective of this study was to measure indicators of potential aggressiveness of end-of-life care in a cohort of adult patients with advanced solid tumor. The secondary objective was to analyze the association between clinicopathological variables and indicators of aggressiveness.

METHODS

Retrospective data analysis was performed on adult patients with solid tumors who received palliative chemotherapy for advanced cancer and died in our hospital between 2017 and 2019. Indicators of aggressiveness of end of life care included chemotherapy use in the last days of life, emergency room visits and hospitalizations (including intensive care unit admissions) in this period, and referral to a palliative care unit before death. Univariate and multivariate analyses were conducted to identify the variables that independently predicted the use of palliative chemotherapy near end of life.

RESULTS

Of the 571 patients included, 128 (22.4%) received chemotherapy within the last 2 weeks of life and 102 (17.8%) start a new chemotherapy regimen 30 days before death. During the last month of life, 168 patients (32.9%) visited emergency room more than once and 117 (20.5%) were hospitalized more than once. A total of 294 patients (51.5%) died in the acute care unit and 285 (49.9%) were referred to the palliative care unit. 24 of them (8.4%) died within 72h after referral.

CONCLUSIONS

The percentage of patients receiving chemotherapy near the end of life as well as the rate of emergency room visits and hospitalizations during this period are much higher than the value of the quality standard established in the literature. According to these indicators, cancer patient care at end of life can be considered overly aggressive. Optimization of palliative care at end of life is necessary.

Outcomes of Patients With Hematologic Malignancies Who Received Inpatient Palliative Care Consultation

PURPOSE

Palliative care (PC) plays an established role in improving outcomes in patients with solid tumors, yet these services are underutilized in hematologic malignancies (HMs). We reviewed records of hospitalized patients with active HM to determine associations between PC consultation and length of stay, intensive care unit stay, 30-day readmission, and 6-month mortality compared with those who were not seen by PC.

METHODS

We reviewed all oncology admissions at our institution between 2013 and 2019 and included patients with HM actively on treatment, stratified by those seen by PC to controls not seen by PC. Groups were compared using Wilcoxon rank-sum, chi-square, and Fisher's exact tests on the basis of the type and distribution of data. Multiple logistic regression models with stepwise variable selection methods were used to find predictors of outcomes.

RESULTS

Three thousand six hundred fifty-four admissions were reviewed, among which 370 unique patients with HM were included. Among these, 102 (28%) patients saw PC, whereas the remaining 268 were controls with similar comorbidities. When compared with controls, PC consultation was associated with a statistically significant reduction in 30-day readmissions (16% v 27%; P = .024), increased length of stay (11.5 v 6 days; P < .001), increased intensive care unit admission (28% v 9%; P < .001), and increased 6-month mortality (67% v 15%; P < .001). These data were confirmed in multivariable models.

CONCLUSION

In this retrospective study, more than two thirds of patients with HM did not receive PC consultation despite having similar comorbidities, suggesting that inpatient PC consultation is underutilized in patients with HM, despite the potential for decreased readmission rates.
