Summary: Little is known about the impact of the COVID-19 pandemic on diagnostic imaging and physician visits at cancer diagnosis. This study from Ontario, Canada, found that the volume of scans decreased at the start of the pandemic but gradually increased afterwards, with ultrasound experiencing the highest decrease and fastest increase. In-person visits dropped significantly, but virtual visits rose dramatically. However, in-person visits increased over time while virtual visits remained stable.

Summary: The COVID-19 pandemic had a significant impact on cancer detection and incidence rates. At the beginning of the pandemic, there was an immediate decline in cancer incidence, although it increased slightly each week afterwards, it has not returned to pre-pandemic levels. Different types of cancers were affected to varying degrees, with the largest declines seen in melanoma, cervical, endocrinologic, and prostate cancers.

Summary: The incidence of head and neck cancer during the first COVID-19 wave in the Netherlands was significantly lower than expected, and the expected increase in incidence during the remainder of 2020 was not observed. Despite the overloaded healthcare system, standard treatment for head and neck cancer patients could be delivered within a shorter time interval.

Summary: The study found that patients undergoing colorectal cancer surgery in 2020 were more likely to have advanced disease at diagnosis compared to those in 2019, with more prominent symptoms, higher clinical stage, and more liver metastases.

Summary: This population-based cohort study in Ontario, Canada, observed significant reductions in cancer service volumes during the COVID-19 pandemic, particularly during the first wave. While most services recovered to prepandemic levels at the end of the first pandemic year, a substantial care deficit likely accrued.

Summary: This study analyzed the impact of the COVID-19 pandemic on patients with non-small-cell lung cancer (NSCLC). The results showed that cancer care services were maintained at the center, and potential adverse effects on prognosis and survival were avoided. The findings provide strategies for healthcare providers to mitigate the impact of future pandemics.

Summary: This study compared the use and short-term outcomes of neoadjuvant-intent vs adjuvant systemic treatment (ST) in breast cancer patients during the COVID-19 era and the pre-COVID-19 era. It found that patients were more likely to receive neoadjuvant ST in the COVID-19 era, but there was limited evidence of substantial impact on short-term outcomes.

Summary: This study aimed to quantify the shift in surgery rate following chemotherapy during the pandemic. A retrospective cohort study in Ontario, Canada found that the proportion of patients receiving surgery 9 months after chemotherapy initiation was higher during the pandemic compared to before, with breast cancer patients experiencing the most significant increase. Further evaluations are needed to understand the long-term consequences of these pandemic-related treatment shifts.

Summary: COVID-19 has significantly impacted the provision of cancer surgery, particularly during the first wave of the pandemic. Although surgical volume recovered to pre-pandemic levels within eight months, it dropped again after the onset of the second wave, resulting in a larger surgical backlog. These findings highlight the need to strengthen the surgical system in order to clear the backlog and meet the needs of newly diagnosed cancer patients requiring surgery.

Summary: This study estimated the long-term clinical impact of breast and colorectal cancer screening interruptions in Canada using a validated mathematical model. The simulations projected a surge of cancer cases and increased cancer deaths as a result of screening interruptions, highlighting the need for effective strategies to minimize potential harm to individuals who missed their screenings.

Summary: The study evaluated the impact of COVID-19 on radiotherapy activity in England, finding a significant decrease in radiotherapy courses and attendance during the pandemic. However, there was an increase in treatments for some cancers, particularly with the rapid increase in the use of hypofractionated regimens.

Summary: The impact of the COVID-19 pandemic on systemic anticancer therapy delivery (SACT) has led to a rapid initial reduction in patient attendance, with subsequent recovery in NHS Scotland. Regional variations in the magnitude of impact were observed, but all regions showed similar rates of recovery. The coordinated national approach and support structures have limited the disadvantage to cancer patients during this time.

Summary: During the COVID-19 pandemic, there was a significant increase in the proportion of patients with inoperable or metastatic disease, a decrease in the proportion of patients diagnosed via screening methods, and a higher 90-day mortality rate after cancer diagnosis. The expected decrease in 5-year survival rates for breast cancer, colorectal cancer, cervix cancer, and melanoma due to increased advanced-stage disease at first referral highlights the importance of collaborative efforts in preventing late cancer diagnoses and ensuring patient safety during the pandemic.

Summary: The study identified a high frequency of delays and disruptions in cancer care services globally due to the reduction in service availability caused by the COVID-19 pandemic. Various categories of delays and disruptions were found to impact cancer treatment, diagnosis, and general health services.
