Epidemiology and survival of lung cancer patients, the impact of COVID-19. (clinical and population-based study).

Aim. The study is aimed at investigating the incidence of lung cancer (LC) at the population level with the analysis of key analytical indicators in the context of coronavirus. Materials and methods. We have used data from the IARC, statistical reference books of P.A. Herzen Moscow Research Oncological Institute, data from N.N. Petrov NMRC of Oncology, and the database of the Population Cancer Registry of St. Petersburg (DB PCR St. Petersburg) for the current study. Results. The study has established a steady decline in the incidence of LC among the male population in the worldwide, in Russia and in St. Petersburg. Among the female population, a significant increase in the incidence has been revealed. On the basis of the database PCR St. Petersburg, the patterns of age-sex indicators of the incidence of LC have been analyzed. It has been established that the largest number of cases is registered in the age group of patients over 70 years old, here the largest losses due to coronavirus have also been identified. An increase in the proportion of early stages of the disease has been noted. The accounting reliability index decreased from 2000 to 2019, with the exception of 2017. Comparison of yearly lethality in the DB PCR St. Petersburg showed a significant difference in the data. The detailed localization structure of LC has been studied, where it has been found out that the first place is occupied by cancer of the upper lobe, bronchi or lung, although over 19 years of observation, a decrease in the proportion of this localization in the total volume of C34 has been noted. The proportion of patients with LC without histological verification has decreased. The influence of the smoking factor on the increased risk of LC has been studied.Copyright © 2022 Izdatel'stvo Meditsina. All rights reserved.

A Retrospective Analysis of the Challenges of Urothelial Cancer Management during the COVID-19 Pandemic at a Single Academic Center in Romania.

The COVID-19 pandemic caused major changes in the healthcare sector due to adaptations required to hospitalize and treat an impressive number of patients. This retrospective study intended to collect reliable information on urothelial cancer patients in Romania. The primary objective was to compare the pre-pandemic and pandemic periods to observe the differences that occurred in the management of patients with urothelial carcinoma. The secondary objective was to determine the risk factors for urothelial cancer progression in the study cohort correlated with the COVID-19 pandemic. All patients that were diagnosed and treated at our clinic with a diagnosis of urothelial carcinoma (transitional cell carcinoma) during 2019-2021 were included in the current study. A total of 1122 eligible unique cases were identified during the study period. The number of patients who underwent intervention in the pre-pandemic year was 421, followed by a 22.6% decrease in 2020 to 326 cases and a 13.1% increase in 2021 to 375 cases. The proportion of muscle-invasive bladder cancer (MIBC) cases was significantly higher during the pandemic years, from 30.5% MIBC cases in 2019 to 37.4% in 2020 and 39.4% in 2021, suggesting a delay in presentations during the pandemic. Stage III and IV (TNM) cases were significantly more frequent, even though approximately 40% of all patients were operated on in stage I. The number of cystectomies increased significantly, from 5.2% in 2019 and 4.3% in 2020 to 10.1% in 2021, while the number of elective surgeries decreased, although no significant difference was observed regarding the in-hospital mortality and disease progression at six months. Patients with stage III and IV at presentation had the highest likelihood of disease progression at six months (HR = 5.61). Distant invasion was the second highest risk factor (HR = 5.13), followed by MIBC type (HR = 2.49). Nevertheless, the duration of hospitalization and year of diagnosis during the COVID-19 pandemic were not significant risk factors for cancer progression at six months. It can be concluded that there was a significant delay in patient presentations in 2020, and we advocate for increased public health awareness for urothelial cancer and increased attention toward the screening and management of these patients in the following years.

The Challenges of Colorectal Cancer Surgery during the COVID-19 Pandemic in Romania: A Three-Year Retrospective Study.

The predictions on the influence of the SARS-CoV-2 pandemic on access to medical services in Romania predicted a 35% drop in oncological hospitalizations in 2020 compared to the previous decade, raising the hypothesis that patients with colorectal cancer can become indirect victims of the ongoing pandemic. Therefore, the aim of the current research was to observe how the COVID-19 pandemic influenced colorectal cancer surgery in Romania, to determine the level of addressability towards specialized care, to compare the cancer staging between the pandemic and pre-pandemic periods, and to observe the risk factors for disease progression. This retrospective study was spread over three years, respectively, from March 2019 to March 2022, and included a total of 198 patients with a history of colorectal cancer surgery. It was decided to perform a parallel comparison of 2019, 2020, and 2021 to observe any significant changes during the pandemic. Our clinic encountered a significant decrease in all interventions during the pandemic; although the number of CRC surgeries remained constant, the cases were more difficult, with significantly more patients presenting in emergency situations, from 31.3% in 2019 to 50.0% in 2020 and 57.1% in 2021. Thus, the number of elective surgeries decreased significantly. The proportion of TNM (tumor-node-metastasis) staging was, however, statistically significant between the pre-pandemic and pandemic period. In 2019, 13.3% of patients had stage IIa, compared with 28.8% in 2020 and 13.1% in 2021. Similarly, the proportion of very advanced colorectal cancer was higher during the pandemic period of 2020 and 2021 (12.0% in 2019 vs. 12.5% in 2020 and 25.0% in 2021), which was represented by a significantly higher proportion of patients with bowel perforation. Patients with an advanced TNM stage had a 6.28-fold increased risk of disease progression, followed by lymphovascular invasion (HR = 5.19). However, the COVID-19 pandemic, represented by admission years 2020 and 2021, did not pose a significant risk for disease progression and mortality. In-hospital mortality during the pandemic also did not change significantly. After the pandemic restrictions have been lifted, it would be advisable to conduct a widespread colorectal cancer screening campaign in order to identify any instances of the disease that went undetected during the SARS-CoV-2 pandemic.

What challenges does the humanitarian crisis and large number of refugees from Ukraine pose for Polish oncology?

The war in Ukraine has led to a massive influx of refugees into Poland, posing a major challenge for the health care system. The large number of refugees will undoubtedly lead to a substantial increase in the number of patients requiring treatment for a wide range of conditions, including cancer. In the present article, we describe and discuss the many difficulties faced by cancer treatment centres in Poland due to these circumstances. Key issues include the lack of proper diagnostic testing in this population and differences in oncological practices between Poland and Ukraine. Other problems include difficulties in obtaining patients' medical records and communication issues caused by the language barrier. In addition, in the context of the ongoing COVID-19 pandemic, the low vaccination rate among Ukrainian refugees is also a significant risk factor. Addressing these challenges will require a comprehensive approach involving the national health care agency and individual cancer centres. This is especially important in oncology due to the interdisciplinary nature of the field, which requires the contribution of specialists from many different fields as well as appropriate funding.

Factors associated with changes in exercise behaviors during the COVID-19 pandemic.

PURPOSE: There is limited information on how the COVID-19 pandemic has changed health behaviors among cancer patients. We examined changes in exercise behaviors since the pandemic and identified characteristics associated with these changes among cancer patients. METHODS: Cancer patients (n = 1,210) completed a survey from August to September 2020 to assess COVID-19 pandemic-related changes in health behaviors and psychosocial factors. Patients were categorized into three groups: exercising less, exercising did not change, and exercising more. Patient characteristics were compared by exercise groups. RESULTS: One-third of the patients reported a decreased amount of regular exercise, while 10% reported exercising more during the pandemic. Patients who exercised less were more likely to be unemployed/retired and have poor health status and psychosocial stressors such as disruptions in daily life while less likely to be former smokers (all p < 0.05). In contrast, patients who exercised more were younger, had stage IV diagnosis, and also reported disruptions in daily life (all p < 0.05). Patients who were living in rural areas were also more likely not to experience changes in exercise habits (all p < 0.05), although rural-urban status was not identified as a strong predictor. CONCLUSION: A significant proportion of cancer patients experienced changes in exercise habits, especially exercising less, during the first 6 months of the COVID-19 pandemic. Age, employment status, tumor stage, health status, smoking status, and psychosocial factors were associated with changes in exercise behaviors. Our results highlight the importance of promoting physical activity guidelines for cancer survivorship during the COVID-19 pandemic and may help improve the identification of cancer patients susceptible to exercising less.
