The Impact of the COVID-19 Pandemic on Breast Cancer Patients

Using Telemedicine to Care for Patients with Breast Cancer: A Natural Quasi-Experimental Study

Introduction

This investigation assessed the clinical characteristics of patients who received care through telemedicine and the clinical impact telemedicine service had on breast cancer patients in a low-income country.

Materials and Methods

This natural experimental study assessed the impact of telemedicine service on cancer outcomes among breast cancer patients at Shaukat Khanum Memorial Trust (SKMT), Pakistan, between January 1st, 2018, to December 31st, 2022. The study group (hybrid group) consisted of patients that had both face-to-face and telemedicine appointments, and the control group (physical group) included patients with only face-to-face encounters.

Results

A total of 3,205 patients were included in the analysis. Among those included in the analysis, 3,188 (99.5 %) were females, and the mean age of the cohort was 48.10 ± 11.94 years. Statistically significant differences were observed between the two groups in age, demographic distribution, disease stage, average number of emergency room visits, mean length of stay in the Intensive care unit, and the final patient status (alive at the end of observation period). However, the binary logistic regression model (forward-LR) suggested that the final patient outcome was related to disease relapse, COVID-19 infection, and age.

Conclusion

Telemedicine clinics, when conducted in parallel with physical clinics (hybrid setup), are safe and have a clinical impact similar to having just physical encounters among breast cancer patients in a low-income country.

Breast cancer incidence, stage distribution, and treatment shifts during the 2020 COVID-19 pandemic: a nationwide population-level study

BACKGROUND

The first COVID-19 wave in 2020 necessitated temporary suspension of non-essential medical services including organized cancer screening programs in Belgium. This study assessed the impact of the pandemic on breast cancer (BC) incidence, stage at diagnosis, and management in Belgium in 2020.

METHODS

All Belgian residents diagnosed with in situ or invasive BC in 2015-2020 in the nationwide, population-based cancer registry database were included. Incidence trends for 2015-2019 were extrapolated to predict incidence and stage distribution for 2020 and compared with the observed values. National healthcare reimbursement data were used to examine treatment strategies. Exact tumor diameter and nodal involvement, extracted from pathology reports, were analyzed for 2019 and 2020.

RESULTS

74,975 tumors were selected for analysis of incidence and clinical stage. Invasive BC incidence declined by -5.0% in 2020, with a drop during the first COVID-19 wave (Mar-Jun; -23%) followed by a rebound (Jul-Dec; +7%). Predicted and observed incidence (in situ + invasive) was not different in patients < 50 years. In the 50-69 and 70 + age groups, significant declines of -4.1% and - 8.4% respectively were found. Excess declines were seen in clinical stage 0 and I in Mar-Jun, without excess increases in clinical stage II-IV tumors in Jul-Dec. There was no increase in average tumor diameter or nodal involvement in 2020. Patients diagnosed in Mar-Jun received significantly more neoadjuvant therapy, particularly neoadjuvant hormonal therapy for patients with clinical stage I-II BC.

CONCLUSIONS

BC incidence decline in 2020 in Belgium was largely restricted to very early-stage BC and patients aged 50 and over. Delayed diagnosis did not result in an overall progression to higher stage at diagnosis in 2020. Observed treatment adaptations in Belgium were successful in prioritizing patients for surgery while preventing tumor progression in those with surgical delay. Continuation of monitoring BC incidence and stage in the future is crucial.

The impact of the COVID-19 pandemic on clinical staging, pathological staging and surgical management of breast cancer patients

Background

This study analyzes the impact of the first six lockdown months during the COVID-19 pandemic on breast cancer (BC) patients at a regional cancer center in western Poland (Greater Poland region).

Materials and methods

Patient age, clinical stage, pathological stage, surgical management, and use of neoadjuvant therapy (NT) for patients diagnosed with BC during the pandemic (March-August 2020, n = 290) were compared with pre-COVID-19 data (March-August 2019, n = 405).

Results

There were statistically significant differences in the average age (58.2 pre-COVID-19 vs. 55.9 during COVID-19, p = 0.014), clinical stage (p = 0.017) with a stage shift (stage I being dominant pre-pandemic, stage II during the pandemic). Additionally, when comparing the 2019 and 2020 groups, there were statistically significant differences in clinically node-positive cases (27% vs. 37%, p = 0.007), pathologically node-positive cases (26% vs. 34%, p = 0.014), and NT use (27% vs. 43%, p = 0.001). Moreover, there was a notable increase in the prevalence of mastectomies from 44% to 53% (p = 0.017) and axillary lymph node dissections from 27% to 33% (p = 0.029).

Conclusions

The first six months of the COVID-19 pandemic had a discernible impact on BC patients in the Greater Poland region. Changes in patient age, clinical stage, pathological stage, and treatment approach were observed during this period. These findings underscore the importance of further research and adaptations in healthcare delivery to address the evolving needs of BC patients during times of crisis.

Delayed diagnosis and increased mortality risk: Assessing the effects of the COVID-19 pandemic on breast cancer recurrence

OBJECTIVES

The COVID-19 pandemic has had a significant global impact since its declaration in March 2020. The COVID-19 pandemic has disproportionately impacted cancer patients, particularly those with breast cancer. This study aims to analyze the effects of the pandemic on women diagnosed with breast cancer recurrence.

METHODS

A cohort study was conducted at a tertiary public hospital in São Paulo State, Brazil. Data were collected from electronic records. Patients diagnosed with breast cancer and experiencing recurrence between January 2011 and March 2022 were included. Survival analysis was performed using the Kaplan-Meier estimator and Cox regression.

RESULTS

The study included 187 patients, 45 in the pandemic group (recurrence after March 23, 2020) and 142 in the pre-pandemic group. Distant recurrences were more frequent in both groups (pre-pandemic: 62.7 %, pandemic: 75.5 %). Compared to the pre-pandemic group (1.8 years), the pandemic group experienced a longer mean time to recurrence detection (2.9 years) and significantly decreased median survival (9 months vs. 22 months). The Cox regression analysis confirmed an increased risk of death for women diagnosed with breast cancer recurrence during the pandemic period (HR = 1.92, 95 % CI 1.19‒3.12).

CONCLUSION

The present study is among the first to investigate the pandemic's specific effects on breast cancer recurrence, revealing concerning delays in detection and a decrease in survival rates. Prompt diagnosis, timely treatment initiation, and comprehensive support are crucial during public health crises. These findings urge healthcare systems to prioritize tailored care for breast cancer patients during pandemics.

The impact of COVID-19 on patients diagnosed with melanoma, breast, and colorectal cancer

BACKGROUND

The COVID-19 pandemic impacted healthcare resource allocation and utilization of preventative medical services. It is unknown if there is resultant stage migration of melanoma, breast, and colorectal cancer when comparing extended time periods before and after the pandemic onset.

METHODS

A retrospective cohort study of melanoma, breast, and colorectal cancer patients was completed. Clinical and pathological staging was compared utilizing 12 and 22-month timeframes before and after the pandemic outbreak.

RESULTS

Between the 22-month pre- and post-COVID-19 groups, breast cancer clinical stage T2 significantly increased, and pathological stage 2 decreased. Colorectal cancer clinical stage T1 decreased, stage T4 increased, and stage 0 decreased in the 22-month groups. In the 12-month groups, melanoma clinical stage T1 increased, and colorectal cancer clinical stage N2 increased.

CONCLUSIONS

Evaluating extended timeframes beyond the immediate pre- and post-COVID-19 period revealed significant increases in clinical staging of breast and colorectal cancer, suggesting advanced disease is becoming more evident as time progresses.

A pragmatic qualitative study to explore women's and clinicians' experience of access to systemic anti-cancer therapies for the treatment of secondary breast cancer

PURPOSE

An estimated 57,000 women are currently living with secondary (metastatic) breast cancer across the UK. Equitable access to treatment has been associated with improved clinical outcomes, however geographical disparities have been reported which remain poorly understood. The purpose of our study was to explore women and clinicians' experience of geographic access to systemic anti-cancer therapies for the treatment of secondary breast cancer.

METHOD

The study setting was the integrated cancer system across the northwest region of Greater Manchester UK. A pragmatic qualitative study design was used. Women aged >18 years with a confirmed SBC diagnosis and clinicians responsible for the care and treatment of women with a secondary breast cancer diagnosis were interviewed using semi structured interviews to elicit their experience and perspectives on geographic access to treatment. Data were analysed using thematic analysis to identify emergent themes.

RESULTS

Eighteen interviews with women and 12 interviews with clinicians were completed. Four meta-themes were identified for geographic access, the influence of the health care system, person centred factors and the impact of Covid-19 on treatment access and receipt.

CONCLUSION

Our study was the first of its kind to explore women and clinicians experience of geographic access to systemic anti-cancer therapies for the treatment of secondary breast cancer. Findings provided a greater understanding of distance decay and the influence of the health care system on treatment access. This included the importance and availability of clinical trials as a potential treatment option. This provided important insights and contributed to ongoing debate.

Impact of the Sars-Cov-2 outbreak on the initial clinical presentation of new solid cancer diagnoses: a systematic review and meta-analysis

BACKGROUND

The COVID-19 pandemic might have delayed cancer diagnosis and management. The aim of this systematic review was to compare the initial tumor stage of new cancer diagnoses before and after the pandemic.

METHODS

We systematically reviewed articles that compared the tumor stage of new solid cancer diagnoses before and after the initial pandemic waves. We conducted a random-effects meta-analysis to compare the rate of metastatic tumors and the distribution of stages at diagnosis. Subgroup analyses were performed by primary tumor site and by country.

RESULTS

From 2,013 studies published between January 2020 and April 2022, we included 58 studies with 109,996 patients. The rate of metastatic tumors was higher after the COVID-19 outbreak than before (pooled OR: 1.29 (95% CI, 1.06-1.57), I2: 89% (95% CI, 86-91)). For specific cancers, common ORs reached statistical significance for breast (OR: 1.51 (95% CI 1.07-2.12)) and gynecologic (OR: 1.51 (95% CI 1.04-2.18)) cancers, but not for other cancer types. According to countries, common OR (95% CI) reached statistical significance only for Italy: 1.55 (1.01-2.39) and Spain:1.14 (1.02-1.29). Rates were comparable for stage I-II versus III-IV in studies for which that information was available, and for stages I-II versus stage III in studies that did not include metastatic patients.

CONCLUSIONS

Despite inter-study heterogeneity, our meta-analysis showed a higher rate of metastatic tumors at diagnosis after the pandemic. The burden of social distancing policies might explain those results, as patients may have delayed seeking care.

The impact of the pandemic on the presentation and treatment of head and neck squamous cell carcinoma at a county hospital

INTRODUCTION

In March 2020, the World Health Organization declared COVID-19 a pandemic, initiating stay-at-home orders which delayed cancer care and screening. The impact on head and neck cancer care in populations at risk has yet to be elucidated. The objective of this investigation is to evaluate how the presentation, diagnosis, and treatment of head and neck squamous cell carcinoma cancer patients at a county hospital were affected by the pandemic.

METHODS

A retrospective review of patients with head and neck squamous cell carcinoma that were diagnosed at a county hospital 365 days before and after stay-at-home orders were initiated. The primary outcomes were duration between diagnosis from imaging and initiation of treatment. Secondary outcomes included mortality, stage, nodal status, and distant metastasis at presentation.

RESULTS

There was a total of 105 diagnoses. Sixty-five (62 %) head and neck squamous cell carcinoma diagnoses were diagnosed before the stay-at-home orders were initiated, and 40 (38 %) after. Eighty percent (32/40) of diagnoses presenting after had stage IV disease compared to 58 % (38/65) in those before (p < 0.05). A higher percentage of patients who presented later had a >30-day delay to biopsy (43 % v. 20 %, OR: 3.0, p < 0.05). This difference was exacerbated by those with laryngeal, oral cavity, or oropharyngeal cancer (45 % v. 15 %, OR: 4.5, p < 0.05). There was a larger delay from diagnosis to treatment after the orders were initiated (68 v. 53, p < 0.05) however there was no difference in one-year mortality (25 % v. 23 %, p > 0.05). This investigation found a 14 % loss to follow-up.

CONCLUSIONS AND RELEVANCE

In this cohort of head and neck squamous cell carcinoma diagnoses at a county hospital, those diagnosed after the stay-at-home orders were initiated presented with more advanced disease. They also had more delays in diagnosis and initiation of treatment. There was no difference in one-year mortality rates between the two groups however there was a significant loss to follow-up, limiting prognostication. These findings serve to better prepare healthcare providers to implement optimized care during future shutdowns related to public health crises.

Impact of the COVID-19 pandemic on clinical presentation, treatments, and outcomes of new breast cancer patients: A retrospective multicenter cohort study

BACKGROUND

The SARS CoV-2 pandemic disrupted healthcare systems. We compared the cancer stage for new breast cancers (BCs) before and during the pandemic.

METHODS

We performed a retrospective multicenter cohort study on the data warehouse of Greater Paris University Hospitals (AP-HP). We identified all female patients newly referred with a BC in 2019 and 2020. We assessed the timeline of their care trajectories, initial tumor stage, and treatment received: BC resection, exclusive systemic therapy, exclusive radiation therapy, or exclusive best supportive care (BSC). We calculated patients' 1-year overall survival (OS) and compared indicators in 2019 and 2020.

RESULTS

In 2019 and 2020, 2055 and 1988, new BC patients underwent cancer treatment, and during the two lockdowns, the BC diagnoses varied by -18% and by +23% compared to 2019. De novo metastatic tumors (15% and 15%, p = 0.95), pTNM and ypTNM distributions of 1332 cases with upfront resection and of 296 cases with neoadjuvant therapy did not differ (p = 0.37, p = 0.3). The median times from first multidisciplinary meeting and from diagnosis to treatment of 19 days (interquartile 11-39 days) and 35 days (interquartile 22-65 days) did not differ. Access to plastic surgery (15% and 17%, p = 0.08) and to treatment categories did not vary: tumor resection (73% and 72%), exclusive systemic therapy (13% and 14%), exclusive radiation therapy (9% and 9%), exclusive BSC (5% and 5%) (p = 0.8). Among resected patients, the neoadjuvant therapy rate was lower in 2019 (16%) versus 2020 (20%) (p = 0.02). One-year OS rates were 99.3% versus 98.9% (HR = 0.96; 95% CI, 0.77-1.2), 72.6% versus 76.6% (HR = 1.28; 95% CI, 0.95-1.72), 96.6% versus 97.8% (HR = 1.09; 95% CI, 0.61-1.94), and 15.5% versus 15.1% (HR = 0.99; 95% CI, 0.72-1.37), in the treatment groups.

CONCLUSIONS

Despite a decrease in the number of new BCs, there was no tumor stage shift, and OS did not vary.

Impact of COVID-19 Pandemic on Advanced Non-small Cell Lung Cancer Treatment at a Japanese Hospital

Background/Aim

The COVID-19 pandemic has forced medical institutions to scale back their practice. Changes in patient behavior seemed to be having an impact. We conducted a survey with the aim of reviewing lung cancer treatment during the pandemic period and identifying problems.

Patients and Methods

We examined the medical records of all patients pathologically diagnosed with non-small cell lung cancer (NSCLC) in our hospital from 2017 to 2022. NSCLC patients were divided into two groups: those diagnosed between 2017 and 2019 (first period) and those diagnosed between 2020 and 2022 (second period).

Results

Within the study period, 267 NSCLC patients (first period: 147 patients, second period: 121 patients) were diagnosed in our hospital. The patients in the two study periods did not differ significantly in age (p=0.613), ECOG performance status (p=0.125), and clinical stage (p=0.354). Tumor size was significantly larger in the second period with a mean of 5.88 cm ± 3.02, compared to 4.24 cm ± 1.76 in the first period (p<0.001). In the standard treatment group, the median survival time was 457 days in the first period and 313 days in the second period (p=0.063). In the best supportive care group, median survival time was 122 days in the first period and 57 days in the second period (p=0.004).

Conclusion

Patients themselves refrained from seeking consultation for lung cancer treatment during the pandemic period. It is inconclusive how to reduce the delay due to the suppression of consultations, but this is an important issue for the future.

Health-Seeking Behavior Returning to Normalcy Overcoming COVID-19 Threat in Breast Cancer

PURPOSE

The coronavirus disease 2019 (COVID-19) outbreak has significantly impacted the diagnosis and treatment of breast cancer. Our study investigated the change in diagnosis and treatment of breast cancer with the progress of COVID-19 pandemic.

MATERIALS AND METHODS

The study group comprised 6,514 recently diagnosed breast cancer patients between January 1, 2019, and February 28, 2021. The patients were divided into two groups: pre-COVID-19 period (3,182; January 2019 to December 2019) and COVID-19 pandemic period (3,332; January 2020 to February 2021). Clinicopathological information related to the first treatment after breast cancer diagnosis was retrospectively collected and analyzed in the two groups.

RESULTS

Among the 6,514 breast cancer patients, 3,182 were in the pre-COVID-19 period and 3,332 were in the COVID-19 pandemic period. According to our evaluation, the least breast cancer diagnosis (21.8%) was seen in the first quarter of 2020. The diagnosis increased gradually except for the fourth quarter in 2020. While early-stage breast cancer was diagnosed 1,601 (48.1%) during the COVID-19 pandemic (p=0.001), the number of surgical treatments increased 4.6% (p < 0.001), and the treatment time was slightly shorter 2 days (p=0.001). The breast cancer subtype distribution was not statistically different between the pre-COVID-19 and COVID-19 period groups.

CONCLUSION

In the early stages of the pandemic, the number of breast cancer cases temporarily decreased; however, they stabilized soon, and no significant differences could be identified in the diagnosis and treatment when compared to the period before the pandemic.

Impact of chemotherapy and/or immunotherapy on neutralizing antibody response to SARS-CoV-2 mRNA-1237 vaccine in patients with solid tumors

Patients with solid tumors have been a risk group since the beginning of the SARS-CoV-2 pandemic due to more significant complications, hospitalizations or deaths. The immunosuppressive state of cancer treatments or the tumor itself could influence the development of post-vaccination antibodies. This study prospectively analyzed 89 patients under chemotherapy and/or immunotherapy, who received two doses of the mRNA-1237 vaccine, and were compared with a group of 26 non-cancer individuals. Information on adverse events and neutralizing antibodies against the ancestral strain of SARS-CoV-2 (WH1) have been analyzed. Local reactions accounted for 65%, while systemic reactions accounted for 46% of oncologic individuals/cancer patients. Regarding the response to vaccination, 6.7% of cancer patients developed low neutralizing antibody levels. Lower levels of neutralizing antibodies between cancer and non-cancer groups were significant in individuals without previous SARS-CoV-2 infection, but not in previously infected individuals. We also observed that patients receiving chemotherapy or chemoimmunotherapy have significantly lower levels of neutralizing antibodies than non-cancer individuals. In conclusion, our study confirms the importance of prioritizing cancer patients receiving anticancer treatment in SARS-CoV-2 vaccination programs.

Outcomes of the same-day discharge following mastectomy before, during and after COVID-19 pandemic

BACKGROUND AND OBJECTIVES

The majority of patients undergoing mastectomy before the COVID-19 pandemic were admitted for 23-h observation to the hospital. Indications for observation included drain care education, pain control and observation for possible early surgical complications. This study compared the rates of outpatient mastectomy before, during, and after the COVID-19 pandemic and indirectly evaluated the safety of same-day discharge.

METHODS

We retrospectively analyzed patients undergoing mastectomy using Current Procedural Terminology code 19303.

RESULTS

A total of 357 patients were included: 113 were treated pre-COVID-19, 82 patients during COVID-19 and 162 post-COVID-19. The rate of outpatient mastectomies tripled during the pandemic from 17% to 51% (p < 0.001); after the pandemic remain high at 48%. The rate of bilateral mastectomies decreased during the pandemic to 30% from 48% prepandemic (p = 0.015). Pectoralis muscle block utilization increased during the COVID-19 period from 36% to 59% (p = 0.002). No difference in complication rates, including surgical site infections, hematomas, and readmissions, pre and during COVID.

CONCLUSIONS

The rate of outpatient mastectomy increased during the COVID-19 pandemic. During this timeframe, perioperative complications did not increase, suggesting the safety of this practice. After the pandemic, the rate of outpatient mastectomy continued to be significantly higher than pre-COVID.

Experiences of Patients in Turkey with Breast Cancer throughout the COVID-19 Pandemic and their Coping Mechanisms: A Qualitative Study

This research was conducted in Turkey to determine the experiences and coping mechanisms of breast cancer patients during the COVID-19 pandemic. The research was conducted using qualitative descriptive phenomenology. Data were collected from ten patients via in-depth interviews through semi-structured questionnaires. Content analysis, incorporating a combination of deductive and inductive approaches, was conducted to determine the themes and subthemes. Interviews were transcribed verbatim, simultaneously with the analysis and collected data. The study data were categorized into 3 contexts, 7 themes and 39 subthemes. The first context titled "Problems accompanying the disease" includes the effects of the pandemic, the fear of being infected with COVID-19 and hospital-related themes. The second context titled "Coping strategies" comprises the themes of coping behaviors and healthy lifestyle behaviors. The last context is titled "Anxiety about being infected, and suggestions for the future". In the study, problems experienced by patients with breast cancer throughout the COVID-19 pandemic were investigated from a broad perspective. Patients treated in chemotherapy units constitute the vulnerable group affected by the pandemic most. Therefore, it is important to investigate the experiences of oncology patients, particularly of patients with breast cancer and their coping strategies, and to take necessary precautions accordingly.

Breast Cancer Management in the Era of Covid-19; Key Issues, Contemporary Strategies, and Future Implications

During the COVID-19 pandemic, several priority diseases were not getting sufficient attention. Whilst breast cancer is a fatal disease affecting millions worldwide, identification and management of these patients did not initially attract critical attention to minimize the impact of lockdown, post-lockdown, and other measures. Breast cancer patients' conditions may not remain stable without proper care, worsening their prognosis. Proper care includes the timely instigation of surgery, systemic therapy, and psychological support. This includes low-and middle-income countries where there are already concerns with available personnel and medicines to adequately identify and treat these patients. Consequently, there was a need to summarize the current scenario regarding managing breast cancer care during COVID-19 across all countries, including any guidelines developed. We systematically searched three scientific databases and found 76 eligible articles covering the medical strategies of high-income countries versus LMICs. Typically, diagnostic facilities in hospitals were affected at the beginning of the pandemic following the lockdown and other measures. This resulted in more advanced-stage cancers being detected at initial presentation across countries, negatively impacting patient outcomes. Other than increased telemedicine, instigating neo-adjuvant endocrine therapy more often, reducing non-essential visits, and increasing the application of neo-adjuvant chemotherapy to meet the challenges, encouragingly, there was no other significant difference among patients in high-income versus LMICs. Numerous guidelines regarding patient management evolved during the pandemic to address the challenges posed by lockdowns and other measures, which were subsequently adopted by various high-income countries and LMICs to improve patient care. The psychological impact of COVID-19 and associated lockdown measures, especially during the peak of COVID-19 waves, and the subsequent effect on the patient's mental health must also be considered in this high-priority group. We will continue to monitor the situation to provide direction in future pandemics.

Changes in breast cancer staging trends among Egyptian women after COVID-19: A retrospective single-center study

OBJECTIVES

Since being declared a global pandemic, the SARS-CoV-2 virus had a significant impact on the entire globe. The pandemic has placed a heavy burden on healthcare systems worldwide, and cancer patients are particularly prone. Despite the fact that initial international reports suggest delays in breast cancer (BC) diagnosis and screening programs, the Egyptian context requires additional research on this topic. To examine whether COVID-19 has changed the pattern of disease presentation before and after the pandemic, focusing on the tumor, node, and metastasis (TNM) staging of the disease at the initial presentation.

METHODS

This single-center, retrospective study of female BC patients initially diagnosed at Baheya Foundation was conducted during the following time frames: from Jan 2019 to Jan 2020 (Pre COVID-19 cohort) and from Mar 2020 to Mar 2021 (post-COVID-19 cohort). We compared the two cohorts in terms of clinical characteristics, tumor characteristics, and the number of days from presentation to treatment. Our primary endpoint was the difference in the TNM stage of BC at the initial presentation.

RESULTS

This analysis included 710 BC patients, 350 from the pre-COVID cohort and 360 from the post-COVID group. We detected a 27.9% increase in late-stage BC (stages III-IV) in the post-pandemic cohort compared to the pre-pandemic (60.1% vs. 47%, p < 0.001). The time from diagnosis to commencement of treatment was significantly longer (28.34 ± 18.845 vs 36.04 ± 23.641 days, p < 0.001) in the post-COVID cohort (mean difference = 7.702, 95% CI 4.54-10.85, p < 0.001). A higher percentage of patients in the post-pandemic cohort received systemic neoadjuvant therapy (p-value for Exact's test for all treatment options = 0.001).

CONCLUSIONS

The number of patients requiring systemic neoadjuvant chemotherapy increased dramatically in the post-pandemic group with advanced stages of BC at presentation. This study highlights the need for proper management of cancer patients during any future pandemic.

Impact of the COVID-19 Pandemic on Breast Cancer Stage at Diagnosis in a Regional Cancer Center in Poland between 2019 and 2021

The COVID-19 pandemic had a negative effect on oncology healthcare services in Poland, with a reduction in the national breast cancer (BC) screening program coverage rates. This article analyzes the impact of the pandemic on BC stage at diagnosis in a regional cancer center in Poland. Records from BC multidisciplinary team (MDT) meetings that took place in the years 2019–2021 were gathered. BC clinical staging was compared. Age-related subgroups were additionally analyzed to reflect possible screening program disruptions. The total number of BC cases fell by 8% in 2020 compared with 2019, with a 14% fall in the screening age group. In 2021, a stage shift was observed, with stage II BC becoming most frequently diagnosed (as opposed to stage I BC in 2019 and 2020). A statistically significant increase in the number of stage III BC cases was observed in 2021.
