Clinical Impact of the COVID-19 Pandemic in Mexican Patients with Thoracic Malignancies

Facing an un-met need in lung cancer screening: The never smokers

Lung cancer (LC) is the leading cause of cancer-related deaths worldwide and the second most common cancer in both men and women. In addition to smoking, other risk factors, such as environmental tobacco smoke, air pollution, biomass combustion, radon gas, occupational exposure, lung disease, family history of cancer, geographic variability, and genetic factors, play an essential role in developing LC. Current screening guidelines and eligibility criteria have limited efficacy in identifying LC cases (50 %), as most screening programs primarily target subjects with a smoking history as the leading risk factor. Implementing LC screening programs in people who have never smoked (PNS) can significantly impact cancer-specific survival and early disease detection. However, the available evidence regarding the feasibility and effectiveness of such programs is limited. Therefore, further research on LC screening in PNS is warranted to determine the necessary techniques for accurately identifying individuals who should be included in screening programs.

Analyzing the impact of the Coronavirus disease 2019 pandemic on initial oncologic presentation and treatment of non-small cell lung cancer in the United States

BACKGROUND

A significantly lower rate of non-small cell lung cancer (NSCLC) screening, greater health care avoidance, and changes to oncologic recommendations were some consequences of the Coronavirus disease 2019 (COVID-19) pandemic affecting the medical environment. We sought to determine how the health care environment during the COVID-19 pandemic affected the oncologic treatment of patients diagnosed with non-small cell lung cancer (NSCLC).

METHODS

This was a retrospective cohort study evaluating patients with NSCLC in the National Cancer Database (2019-2020). Patients were divided into prepandemic (2019) and pandemic (2020) cohorts, and patient, oncologic, and treatment variables were compared. Multivariable logistic regression was performed to control for the impact of demographic characteristics on oncologic variables and the impact of oncologic variables on treatment variables.

RESULTS

The study population comprised 250,791 patients, including 114,533 patients (45.7%) in the pandemic cohort. There were 15% fewer new NSCLC diagnoses during the pandemic compared with prepandemic. Patients diagnosed during the pandemic had more advanced clinical TNM stage on presentation (P < .0001) and were more likely to have tumors in overlapping lobes or in a main bronchus (P = .0002). They were less likely to receive cancer treatment (P < .0001) and to undergo primary resection (P < .0001) and more likely to receive adjuvant systemic therapy (P = .004) and a combination of palliative treatment regimens (P < .0001). After risk adjustment, all these differences remained statistically significant (P < .05).

CONCLUSIONS

The COVID-19 pandemic was associated with increased clinical stage at presentation for patients with NSCLC, which impacted subsequent treatment strategies. However, treatment differed minimally when controlling for cancer stage. Future studies will examine the impact of these differences on overall survival and cancer-free survival.

A Comparative Multicenter Cohort Study Evaluating the Long-Term Influence of the Strict Lockdown during the First COVID-19 Wave on Lung Cancer Patients (ARTEMISIA Trial)

The consequences of the strict health restrictions during the first wave of COVID-19 on lung cancer (LC) patients are not known. This cohort study evaluated the impact of the initial lockdown on management of and long-term outcome in LC patients. This exposed-unexposed-type study included two evaluation periods of 6 months each in non-selected patients; one began on the first day of lockdown in 2020, and the other in 2019 during the same calendar period. Various indicators were compared: clinical profiles, management delays and overall survival beyond 2 years. A total of 816 patients from 7 public or private centers were enrolled. The clinical characteristics of the patients in 2020 did not differ from those in 2019, except that the population was older (p = 0.002) with more non-smokers (p = 0.006). Delays for pre-therapeutic medical management were generally reduced after the first imaging in 2020 (1.28 [1.1-1.49]). In the multivariate analysis, being part of the 2020 cohort was correlated with better prognosis (HR = 0.71 [0.5-0.84], p < 0.001). The gain observed in 2020 mainly benefited non-smoking patients, along with ECOG PS 0-2 (p = 0.01), stage 4 (p = 0.003), squamous cell carcinoma (p = 0.03) and receiving systemic therapy (p = 0.03). In conclusion, the first lockdown did not exert any deleterious impact on LC patients.

Impact of coronavirus disease 2019 on lung cancer patients: A meta-analysis

Background

The coronavirus disease 2019 (COVID-19) pandemic poses a great challenge to the treatment of lung cancer patients.

Materials and methods

The PubMed, Embase, and Web of Science databases were searched for studies published before March 15, 2022, and Stata 14.0 software was used to perform a meta-analysis with a random-effects model. The odds ratio (OR) along with the corresponding 95% confidence interval (CI) was reported.

Results

Our meta-analysis included 80 articles with 318,352 patients involved. The proportion of lung cancer patients infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was 2.4% (95% CI: 0.02-0.03) prior to the Omicron variant outbreak. Among COVID-19 patients, those with lung cancer showed a higher mortality rate than those with other types of malignant solid tumors (OR = 1.82, 95% CI: 1.61-2.06) and non-cancer patients (OR = 4.67, 95% CI: 3.61-6.05); however, no significant difference was observed in the mortality rate between patients with lung cancer and those with hematologic malignancies (OR = 1.07, 95% CI: 0.85-1.33). SARS-CoV-2 infection significantly increased the mortality rate in lung cancer patients (OR = 8.94, 95% CI: 6.50-12.31). By contrast, the all-cause mortality rate in lung cancer patients (OR = 1.04, 95% CI: 0.69-1.57) and the proportion of patients diagnosed with advanced lung cancer (OR = 1.04, 95% CI: 0.85-1.27) did not significantly change before and after the pandemic.

Conclusions

More attention should be paid on improving the health of lung cancer patients during the COVID-19 pandemic.

Assessment of Cancer Patients' Mental Health during the Coronavirus Pandemic in Serbia

This study aimed to determine the impact of the COVID-19 pandemic on the mental health of cancer patients in Serbia. Data were collected between April-May 2021 using an online questionnaire, which estimated depression, anxiety, and stress in a sample of 221 cancer patients. The Depression, Anxiety, and Stress Assessment Scale (DASS-21) was used to assess the cancer patients' affective status. The T test of independent samples and the one-way analysis of variance (ANOVA), as well as multiple linear regression analysis, have been used as well. The results showed that moderate to extremely severe depression, anxiety, and stress symptoms were present in 33.9%, 21.2%, and 26.7% of patients, respectively. Older patients and those who assessed their socioeconomic and health status as better were less anxious, depressed, and stressed. The study shows that the patients who have stated that medical help has been available significantly differ from those patients who have not had available medical help, meaning that they have shown lower scores on the scales of depression and stress. When it comes to the availability of medical help during the pandemic, statistically significant differences among patients on the scale of anxiety have not been proven. It has been determined that statistically important differences exist between patients who have needed psychological help and those who have not needed it when it comes to the results on all of the three subscales. The patients who have expressed the need for psychological help have higher levels of depression, anxiety, and stress. The patients who have not had available psychological help have higher levels of depression, anxiety, and stress when compared to the patients who have had available psychological help.

The prevalence of psychological disorders among cancer patients during the COVID-19 pandemic A meta-analysis

Purpose

We aimed to assess the prevalence rate (PR) of depression, anxiety, posttraumatic stress disorder (PTSD), insomnia, distress, and fear of cancer progression/recurrence among patients with cancer during the COVID‐19 pandemic.

Methods

Studies that reported the PR of six psychological disorders among cancer patients during the COVID‐19 pandemic were searched in PubMed, Embase, PsycINFO, and Web of Science databases, from January 2020 up to 31 January 2022. Meta‐analysis results were merged using PR and 95% confidence intervals, and heterogeneity among studies was evaluated using I² and Cochran's Q test. Publication bias was examined using funnel plots and Egger's tests. All data analyses were performed using Stata14.0 software.

Results

Forty studies with 27,590 participants were included. Pooled results showed that the PR of clinically significant depression, anxiety, PTSD, distress, insomnia, and fear of cancer progression/recurrence among cancer patients were 32.5%, 31.3%, 28.2%, 53.9%, 23.2%, and 67.4%, respectively. Subgroup analysis revealed that patients with head and neck cancer had the highest PR of clinically significant depression (74.6%) and anxiety (92.3%) symptoms. Stratified analysis revealed that patients with higher education levels had higher levels of clinically significant depression (37.2%). A higher level of clinically significant PTSD was observed in employed patients (47.4%) or female with cancer (27.9%).

Conclusion

This meta‐analysis evaluated the psychological disorders of cancer patients during the COVID‐19 outbreak. Therefore, it is necessary to develop psychological interventions to improve the mental health of cancer patients during the pandemic.

The psychosocial and emotional experiences of cancer patients during the COVID-19 pandemic: A systematic review

BACKGROUND

COVID-19 was declared a pandemic by the World Health Organization on March 11th, 2020. Global social lockdowns were instigated to reduce spread and prevent health-services from becoming overwhelmed. People having treatment for cancer are known to have heightened psychological/emotional burden. The combined impact of managing pandemic regulations alongside this may present additional burden. The purpose of this systematic review is to examine current evidence of the psychological and emotional impact of COVID-19 on people with cancer, early in the pandemic.

METHODS

Five electronic databases were searched (Embase, Global Health, HMIC, PsychINFO, CINAHL) from September 2019 to October 2021. Qualitative, quantitative and mixed-method primary research studies exploring emotional and psychological impacts of COVID-19 on cancer patients, limited to English language, were included. Quality appraisal was conducted using the MMAT.

RESULTS

Fifty-one papers, with 27,356 people from 21 countries treated for cancer, were included. 43 studies were quantitative with a survey method approach, six studies qualitative and four used a mixed methods design. MMAT score was mostly two or three. Four themes were identified: Emotional aspects and Quality of Life; Psychosocial aspects; Impact of COVID-19 on self; Impact of COVID-19 on cancer, with themes overlapping.

CONCLUSION

Whilst emotional/psychological impacts such as anxiety, isolation, employment fears, and uncertainty about the future were potentially universal concerns early in the pandemic, they may have been particularly acute for people living with cancer and represent complex, overlapping factors. As COVID-19 continues to impact health-services and society, it is important to focus on any ongoing impact to the experience of cancer patients. Most of the studies reviewed used tools that do not provide deeper understanding of how and why emotional states of people with cancer were affected. Further qualitative work may reveal patterns of what was unique to cancer patients during the pandemic, compared to general populations.
