Palliative care and psychosocial care in metastatic non-small cell lung cancer: factors affecting utilisation of services and impact on patient survival

Survivorship concerns among individuals diagnosed with metastatic cancer: Findings from the Cancer Experience Registry

INTRODUCTION

Individuals with metastatic cancer experience many medical, physical, and emotional challenges due to changing medical regimens, oscillating disease states, and side effects. The purpose of this study was to describe the type and prevalence of survivorship concerns reported by individuals with metastatic cancer, and their associations with cancer diagnosis, treatment, and socio-demographic variables.

METHODS

This study utilized data from the Cancer Support Community's Cancer Experience Registry. Individuals were included if they self-reported a solid tumor metastatic cancer and completed CancerSupportSource, which evaluates five domains of concerns (emotional well-being, symptom burden, body image/healthy lifestyle, healthcare team communication, and relationships/intimacy). Multivariable linear regression examined associations between independent predictors of each survivorship concern domain.

RESULTS

Of the 403 included participants, individuals reported a metastatic diagnosis of breast (43%), colorectal (20%), prostate (7%), lung (7%), gynecologic cancer (6%) and other. Nearly all (96%) reported at least one survivorship concern, with the most prevalent concern about cancer progression or recurrence. Survivorship concerns were higher across multiple domains for individuals unemployed due to disability. Individuals who were less than five years since diagnosis reported higher concerns related to emotional well-being, symptom burden, and healthcare communication compared to those more than five years since diagnosis.

CONCLUSION

Individuals with metastatic cancer experience a variety of moderate-to-severe survivorship concerns that warrant additional investigation.

IMPLICATIONS FOR CANCER SURVIVORS

As the population of individuals with metastatic cancer lives longer, future research must investigate solutions to address modifiable factors associated with survivorship concerns, such as unemployment due to disability.

Mapping the clinical care pathways for advanced stage non-small cell lung cancer patients in Victoria: A retrospective cohort study of supportive and palliative care

The lung cancer Optimal Care Pathway recommends supportive care and palliative care integration throughout its various steps, with early referral to appropriate services improving the quality of life in advanced stage non-small cell lung cancer patients. Using Victorian Lung Cancer Registry data and linked administrative datasets, this retrospective cohort study mapped clinical care pathways of 525 Stage III-IV non-small cell lung cancer patients in Victoria to 11 recommendations in the Optimal Care Pathway, identifying unwarranted variations in clinical care. Supportive care and palliative care delivery were further examined to understand the involvement and timing of specialist care teams. Our findings showed that palliative care utilization is highest at the time of treatment, despite recommendations that it should be provided early after diagnosis to improve patient outcomes and satisfaction. Early supportive care screening was observed in half the cohort and almost three-quarters of the patients had been presented at a multidisciplinary meeting. Multidisciplinary meeting presentations and supportive care provide an opportunity to improve communication about palliative care needs and integration into routine clinical practice, such as at the time of treatment planning.

Lung cancer treatment patterns and factors relating to systemic therapy use in Australia

AIM

Systemic therapies for lung cancer are rapidly evolving. This study aimed to describe lung cancer treatment patterns in New South Wales, Australia, prior to the introduction of immunotherapy and latest-generation targeted therapies.

METHODS

Systemic therapy utilization and treatment-related factors were examined for participants in the New South Wales 45 and Up Study with incident lung cancer ascertained by record linkage to the New South Wales Cancer Registry (2006-2013). Systemic therapy receipt to June 2016 was determined using medical and pharmaceutical claims data from Services Australia, and in-patient hospital records. Factors related to treatment were identified using competing risks regressions.

RESULTS

A total of 1,116 lung cancer cases were identified with a mean age at diagnosis of 72 years and median survival of 10.6 months. Systemic therapy was received by 45% of cases. Among 400 cases with metastatic non-small cell lung cancer, 51% and 28% received first- and second-line systemic therapy, respectively. Among 112 diagnosed with small-cell lung cancer, 79% and 29% received first- and second-line systemic therapy. The incidence of systemic therapy was lower for participants with indicators of poor performance status, lower educational attainment, and those who lived in areas of socioeconomic disadvantage; and was higher for participants with small-cell lung cancer histology or higher body mass index.

CONCLUSION

This population-based Australian study identified patterns of systemic therapy use for lung cancer, particularly small-cell lung cancer. Despite a universal healthcare system, the analysis revealed socioeconomic disparities in health service utilization and relatively low utilization of systemic therapy overall.

A Retrospective Study on Using a Novel Single Needle Cone Puncture Approach for the Iodine-125 Seed Brachytherapy in Treating Patients With Thoracic Malignancy

Background

Patients with progressive thoracic malignancy characterized by large irregular tumors with necrosis and life-threatening symptoms lack effective treatments. We set out to develop a single needle cone puncture method for the Iodine-125 seed (SNCP-¹²⁵I) brachytherapy, and aim to report the initial results.

Methods

294 patients with advanced thoracic malignancy were treated with local SNCP-¹²⁵I brachytherapy between March 2009 and July 2020, followed by thorough evaluation of clinical outcome, overall survival (OS), progression-free survival (PFS) and procedure-related complications after treatment.

Results

The overall response rate (ORR) among the treated patients was 81.0% (238/294). Life-threatening symptoms due to tumor oppression, hemoptysis and large irregular tumor with necrosis were successfully alleviated after the SNCP-¹²⁵I treatment with a remission rate at 91% to 94%. The median OS and PFS were 13.6 months and 5.8 months, respectively. Procedure-related side effects including pneumothorax (32/294), blood-stained sputum (8/294), subcutaneous emphysema (10/294), puncture site bleeding (16/294) and chest pain (6/294) were observed. Patients who were able to follow with chemotherapy or immunotherapy experienced extended OS and PFS, as compared with patients who opted to receive hospice care (16.5 months Vs. 11.2 months). Further pathological and immunological analysis showed that SNCP-¹²⁵I induced tumor lymphocytes infiltration and long-term tumor necrosis.

Conclusion

SNCP-¹²⁵I brachytherapy effectively eliminates life-threatening symptoms due to local tumor oppression, hemoptysis and large irregular and necrotic tumors in patients with unresectable chest malignancy and significantly induces local tumor regression. SNCP-¹²⁵I brachytherapy combines with chemotherapy significantly prolong OS and PFS compare with SNCP-¹²⁵I brachytherapy alone.

Palliative Thoracic Radiotherapy for Non-Small Cell Lung Cancer in Outpatients: Reasons for Unplanned Hospitalization and Its Impact on Survival

Background

The aims of the study were to examine the rates of and reasons for unplanned hospitalization after start of palliative radiotherapy or chemoradiation (CRT), and to study whether unplanned hospitalization deteriorates patients’ prognosis. In addition, risk factors were identified.

Methods

A retrospective review of 136 patients treated with palliative radiotherapy or CRT was performed. Inclusion criteria were prescribed total dose at least 30 Gy and outpatient at the start of treatment. Uni- and multivariate analyses were employed.

Results

Fifty-eight patients (43%) were hospitalized within 3 months from start of radiotherapy or CRT. Their median overall survival was 6.7 months as compared to 11.1 months in non-hospitalized patients (P = 0.09). The median length of hospitalization was 8 days (range 1 - 61). In patients with possibly treatment-related hospitalization (n = 32), median survival was 5.0 months, significantly shorter than the 11.1 months observed in the remaining patients (P = 0.006). In multivariate analysis, only one variable was significantly associated with higher risk of unplanned hospitalization: previous hospitalization in the last 4 weeks before commencing radiotherapy or CRT.

Conclusions

Unplanned hospitalization occurred frequently in a standard care setting without early involvement of a dedicated palliative team. Patients with preceding hospitalization might represent a group that is particularly vulnerable, thus qualifying for a targeted intervention aiming at continued outpatient care.

Early High-Grade Thoracic Toxicity After Palliative Radiotherapy for Non-Small Cell Lung Cancer

INTRODUCTION

Palliative radiotherapy or chemoradiotherapy (CRT) for non-small cell lung cancer (NSCLC) may cause thoracic toxicities due to the radiation dose delivered to the lungs, heart, and esophagus. We studied severe thoracic toxicities resulting in hospitalization or death during the acute and sub-acute phase, i.e., three months from commencing radiotherapy. In addition, risk factors were identified.  Methods: A retrospective review of 165 patients treated with three-dimensional conformal palliative radiotherapy or CRT was performed. The prescribed total dose was equivalent to at least 30 Gy in 10 fractions. Uni- and multivariate analyses were employed.

RESULTS

Twelve patients (7%) were hospitalized within three months from the start of radiotherapy or CRT. Six patients were hospitalized for esophagitis, three for dyspnea most likely caused by pneumonitis, and three for cardiac arrhythmia. Fatal toxicity was not observed. However, 19% of the 165 patients died from tumor-related causes during the time period of interest. In multivariate analysis, the only esophageal dose was significantly associated with the risk of hospitalization.  Conclusion: The safety profile of palliative radiotherapy or CRT in the acute and subacute phases was satisfactory. The hospitalization rate can be reduced by lowering the esophageal dose, as long as safe lung and heart doses can be maintained.

Association of tumor mutation burden and epidermal growth factor receptor inhibitor history with survival in patients with metastatic stage III/IV non-small-cell lung cancer: A retrospective study

OBJECTIVES

Lung cancer is the leading cause of cancer-related deaths worldwide. However, factors associated with the survival of patients with advanced non-small-cell lung cancer (NSCLC) who received only hospice care are largely unclear. In this study, we aimed to determine the prognostic factors correlated with survival in patients with advanced NSCLC who had undergone hospice care only.

METHODS

A total of 102 patients with recurrent stage III/IV NSCLC after traditional treatment failure were investigated. Survival was measured from the date of enrollment to December 2019 or the time of death. Tumor tissues were collected, and DNA sequencing was performed to identify somatic mutations. Data on clinical factors of patients were collected and analyzed by univariate and multivariate analyses. Overall survival analysis was conducted using the Kaplan-Meier method.

RESULTS

The 6-month, 1-year, and 2-year overall survival rates of the 102 patients with metastatic NSCLC were 17.65%, 3.92%, and 0.98%, respectively. The median overall survival of the 102 patients was 3.15 months. Tumor location in the peripheral lung, epidermal growth factor receptor (EGFR) inhibitor history, low tumor mutation load, adenocarcinoma, and poor performance status score were associated with prolonged survival compared with tumor location in the central lung, no EGFR inhibitor history, high tumor mutation load, squamous cell carcinoma, and good performance status score (p=0.045, p=0.003, p=0.045, p=0.021, and p=0.0003, respectively).

CONCLUSIONS

EGFR inhibitor treatment history and tumor mutation load are risk factors for the overall survival of patients with stage III/IV NSCLC who have undergone only hospice care. These results provide a critical clinical basis for further study of nontraditional anti-tumor responses induced by EGFR inhibitors.

Referral Characteristics of Palliative Care Service in Patients With Advanced Non-Small Cell Lung Cancer in a Tertiary Cancer Center

BACKGROUND

The American Society of Clinical Oncology recently recommends patients with metastatic non-small cell lung cancer (NSCLC) should be offered palliative care services earlier. We sought to investigate the timing of palliative care referral of Chinese patients with NSCLC in our center.

METHOD

Retrospective medical data including demographic characteristics and referral information were collected for analysis. Overall survival (OS) was calculated as the time since cancer diagnosis till patient's death. The time interval from palliative care (PC) referral to a patient's death (PC-D) was calculated. The PC-D/OS ratio was calculated to illustrate the comparison of the duration of PC in the overall length of disease.

RESULTS

The mean age of 155 patients with advanced NSCLC was 62.83 years. Before referral to PC, 128 patients received anticancer treatment including surgeon (46.5%). Sixty-three (40.6%) patients died in palliative care unit. The median OS of 144 patients with end cutoff was 19 months (mean = 31.49, 95% confidence interval [CI] = 25.86-37.12). The median PC-D was 41 days (mean = 73.84, 95% CI = 60.37-87.40). The mean interval of PC-D/OS of 144 patients with definitely death time was 0.22 (SD: 0.27, 95% CI: 0.17-0.26). The median interval was 0.089. More than half of patients (n = 75, 51.8%) underwent PC less than 1% time (PC-D/OS < 0.1) of their whole disease course. Patients who were indigenous to Shanghai (P = .013) and who had brain metastasis (P = .072) had the potential longer PC-D/OS ratio. A high proportion of patients reported loss of appetite (92.8%) and fatigue (91.4%) at the initial of referral to PC.

CONCLUSION

This retrospective study, in a population of patients with advanced NSCLC, gave detailed information about PC services in a tertiary cancer center.

Patterns of Support Service, Emergency Department, and Hospital Utilization in Patients with Advanced Cancer: A Descriptive Study

Context:

Palliative care in oncology provides multiple benefits, however access to specialty palliative clinicians is limited in community cancer centers. Individual support services are more often available, but little is known on the utilization and impact of these services.

Objectives:

To describe the utilization of outpatient support services in the advanced cancer population and the association with ED and hospital use in a community setting.

Methods:

A retrospective chart review of 314 patients with advanced cancer of lung, gastrointestinal, genitourinary, and gynecologic origin was conducted. Data collected included demographics, descriptive data, type and number of support services (symptom management, nurse navigator, social worker, nutrition, financial counselor, chaplain, and oncology clinical counselor) within 90 days of diagnosis and descriptions of ED visits/hospitalizations within 12 months of diagnosis. Support services were available to patients by referral.

Results:

29.6% of patients were deceased within 6 months and were considered to have severe disease. Patients with severe disease had a significantly greater mean number of support services than patients with non-severe disease (8.9 vs 6.0, p=0.001) and had a greater mean number of visits per year to the ED (6.4 vs 1.8, p<0.001). A greater proportion of patients with severe disease had palliative consultations (48.9% vs 21.7%, p<0.001), but 65.5% of palliative consultations occurred after an ED or hospital visit.

Conclusion:

Our data demonstrated that advanced cancer patients with severe disease had increased healthcare utilization in all areas measured. Despite high utilization, outpatient support services used in a reactive manner were not effective in reducing ED or hospital visits.
