Flexible bronchoscopy for lung cancer diagnosis in patients aged ≥85 years

AIM

Flexible bronchoscopy (FB) is a common modality for the diagnosis of lung cancer. Recently, the number of older patients with lung cancer is increasing, and FB is being utilized more for these patients.

METHODS

FB carried out in patients aged ≥85 years at St. Marianna University Hospital, Kawasaki, Japan, were reviewed. The indication of FB was decided on a case-by-case basis, taking into consideration the condition of the patient, which included mental status and accessibility of the lesion. Outcomes included complications, diagnostic yields, treatment options and survival after FB evaluation.

RESULTS

From April 2015 to March 2019, 1604 diagnostic FBs were carried out. A total of 28 were carried out for the diagnosis of lung cancer (19 transbronchial lung biopsy, 9 transbronchial needle aspiration) in patients aged ≥85 years. Although there were three complications reported (pneumonia, fever, asthma exacerbation), they were successfully treated. A total of 19 cases were diagnosed with malignancy; five were treated with stereotactic body radiation therapy, five were prescribed targeted therapy, two underwent surgery and one was treated by cytotoxic monotherapy. Six patients were not included for active treatment. A total of 12 patients who received active treatment for lung cancer reported a 2-year survival rate of >60%.

CONCLUSIONS

FB for lung cancer diagnosis in patients aged ≥85 years were carried out with acceptable safety and diagnostic yield. Considering the development of less invasive therapeutic measures for lung cancer, FB is safe and valuable in individuals aged ≥85 years suspected of lung cancer with therapeutic indications.

The role for chemotherapy in 80 years and older patients with metastatic non-small cell lung cancer: A National cancer database analysis

BACKGROUND

There are limited data on the role for chemotherapy in patients > 80 years old with advanced stage non-small cell lung carcinoma (NSCLC). We used the National Cancer Database (NCDB) to evaluate treatment patterns and outcomes for patients ≥80 years old with advanced NSCLC.

METHODS

We identified patients diagnosed with metastatic NSCLC between 2004 and 2014. We divided them into two groups: < 80 years old (n = 218,365) and ≥ 80 years old (n = 33,352). Patient characteristics including median age at diagnosis, gender, ethnicity, histology, chemotherapy status, tumor grade, treatment center, insurance status, income, education, and Charlson-Deyo co-morbidity index were collected. Continuous variables were compared using t-test and categorical variables were compared using chi-square or Fisher's exact test. Multivariable (MV) and propensity matched analyses were performed to analyze the impact of chemotherapy on overall survival.

RESULTS

We identified 33,352 patients > 80 years old diagnosed with advanced NSCLC. Only 29 % received chemotherapy, those who received chemotherapy had improved median overall survival of 8 months compared to 2 months in patients not receiving chemotherapy; adjusted hazards ratio (HR) 0.46; confidence interval (CI) 0.45-0.47; p < .001. MV analysis showed benefit of chemotherapy in all age subgroups (80-84 years, 85-89 years and 90+ years; p < .0001) and it was confirmed by propensity matched analysis. Patients receiving multiagent chemotherapy had improved 1-year survival of 35.5 % compared to 32.8 % with single agent chemotherapy (adjusted HR 0.92; CI 0.88-0.96; p < .001). Despite benefit from chemotherapy, the proportion of patients age ≥ 80 years receiving chemotherapy did not change over time.

CONCLUSIONS

Chemotherapy improved overall survival in ≥80 years old patients with advanced stage NSCLC. Despite improved survival and an increase in the proportion of ≥80 years old patients diagnosed with advanced NSCLC, less than one-third receive chemotherapy.

Survival score to characterize prognosis in inoperable stage III NSCLC after chemoradiotherapy

Background

Stage III non-small cell lung cancer (NSCLC) represents a heterogeneous disease regarding principal patient- and tumor characteristics. A simple score may aid in personalizing multimodal therapy.

Methods

The data of 99 consecutive patients with performance status ECOG 0-1 treated until the end of 2016 with multimodal approach for inoperable NSCLC (UICC 7^th edition stage IIIA/B) were evaluated. Patient- and tumor-related factors were examined for their impact on overall survival. Factors showing a negative association with prognosis were then included in the score. Three subgroups with low, intermediate and high-risk score were defined. The results were then validated in the prospective cohort, which includes 45 patients.

Results

Most Patients were treated with concurrent (78%) or sequential (11%) chemoradiotherapy. 53% received induction chemotherapy. Median survival for the entire cohort was 20.8 (range: 15.3-26.3) months. Age (P=0.020), gender (P=0.007), pack years (P=0.015), tumor-associated atelectasis (P=0.004) and histology (P=0.004) had a significant impact on overall survival and were scored with one point each. Twelve, 59 and 28 patients were defined to have a low (0-1 points), intermediate (2-3 points) and high-risk (4-5 points) score. Median survival, 1-, 2- and 3-year survival rates were not reached, 100%, 83% and 67% in the low, 22.9 months, 80%, 47% and 24% intermediate and 13.7 months, 57%, 25% and 18% high-risk patients, respectively (P<0.001). Median survival was not reached in prospective cohort; analysis has revealed a trend for the 1-year survival rates with 100% for the low, 93% intermediate and 69% high-risk patients (P=0.100).

Conclusions

The score demonstrated remarkable survival differences in inoperable stage III NSCLC patients with good performance status receiving multimodal therapy.

Clinicopathological characteristics and prognosis of pulmonary large cell neuroendocrine carcinoma aged ≥65 years

Objective

The present study was designed to better characterize the clinicopathological features and prognosis in patients aged ≥65 years with pulmonary large cell neuroendocrine carcinoma (LCNEC).

Methods

Eligible patients with pulmonary LCNEC were retrieved from the Surveillance, Epidemiology, and End Results database between January 2004 and December 2013. The primary endpoints included cancer-specific survival (CSS) and overall survival (OS).

Results

Data of 1,619 eligible patients with pulmonary LCNEC were collected. These patients were subsequently categorized into two groups: 890 patients in the older group (age ≥65 years), and 729 in the younger group (age <65 years). More patients were of white ethnicity, stage I, married, and with tumor size <5 cm in the older group in comparison to the younger group. However, there were a significantly lower proportion of patients undergoing surgery, chemotherapy, and radiotherapy in the older group. The 5-year CSS rates of the younger group and older group were 23.94% and 17.94% (P = 0.00031), respectively, and the 5-year OS rates were 20.51% and 13.47% (P < 0.0001), respectively. Multivariate analyses indicated that older age (CSS: HR 1.20, 95% CI [1.07-1.36], P = 0.0024; OS: HR 1.26, 95% CI [1.12-1.41], P < 0.0001) was an independent risk factor for poor prognosis. The mortality risk of the elderly increased in almost every subgroup, especially in OS. Finally, significant predictors for better OS and CSS in patients over age 65 included tumor size <5 cm, lower stage, and receiving surgery, chemotherapy, or radiotherapy.

Conclusion

The prognosis of patients aged ≥65 years with pulmonary LCNEC was worse than that of younger patients. However, active and effective therapy could significantly improve the survival of older patients with pulmonary LCNEC.

Current treatment of older patients with recurrent gynecologic cancer

PURPOSE OF REVIEW

Gynecologic cancer patients of elderly has been increasing rapidly. Useful information on older patients, especially, with recurrent gynecological cancer is extremely limited.

RECENT FINDINGS

A unified concept for assessing treatment risk was proposed when providing cancer treatment to older patients. Fit: patients capable of withstanding the same standard treatment as healthy younger patients; Vulnerable: patients incapable of withstanding the same standard treatment as healthy younger patients, but capable of undergoing some sort of treatment; and Frail: patients incapable of withstanding the same standard treatment as healthy younger patients, and also unsuitable to undergo any kind of active treatment.It is important to identify vulnerability by using geriatric assessment as a patient background factor, to intervene if treatment is required, and to modify the intensity of treatment in an attempt to extend overall survival, decrease adverse events, improve health-related quality of life, and reduce medical costs.

SUMMARY

It is important to carry out a pretreatment functional assessment of older cancer patients using the geriatric assessment, and to choose the method of treatment for older patients in light of its results with recurrent gynecological cancer in addition to chronological age.
