Evaluation of COVID-19 impact on DELAYing diagnostic-therapeutic pathways of lung cancer patients in Italy (COVID-DELAY study): fewer cases and higher stages from a real-world scenario.

INTRODUCTION: COVID-19 has disrupted the global health care system since March 2020. Lung cancer (LC) patients (pts) represent a vulnerable population highly affected by the pandemic. This multicenter Italian study aimed to evaluate whether the COVID-19 outbreak had an impact on access to cancer diagnosis and treatment of LC pts compared with pre-pandemic time. METHODS: Consecutive newly diagnosed LC pts referred to 25 Italian Oncology Departments between March and December 2020 were included. Access rate and temporal intervals between date of symptoms onset and diagnostic and therapeutic services were compared with the same period in 2019. Differences between the 2 years were analyzed using the chi-square test for categorical variables and the Mann-Whitney U test for continuous variables. RESULTS: A slight reduction (-6.9%) in newly diagnosed LC cases was observed in 2020 compared with 2019 (1523 versus 1637, P = 0.09). Newly diagnosed LC pts in 2020 were more likely to be diagnosed with stage IV disease (P < 0.01) and to be current smokers (someone who has smoked more than 100 cigarettes, including hand-rolled cigarettes, cigars, cigarillos, in their lifetime and has smoked in the last 28 days) (P < 0.01). The drop in terms of new diagnoses was greater in the lockdown period (percentage drop -12% versus -3.2%) compared with the other months included. More LC pts were referred to a low/medium volume hospital in 2020 compared with 2019 (P = 0.01). No differences emerged in terms of interval between symptoms onset and radiological diagnosis (P = 0.94), symptoms onset and cytohistological diagnosis (P = 0.92), symptoms onset and treatment start (P = 0.40), and treatment start and first radiological revaluation (P = 0.36). CONCLUSIONS: Our study pointed out a reduction of new diagnoses with a shift towards higher stage at diagnosis for LC pts in 2020. Despite this, the measures adopted by Italian Oncology Departments ensured the maintenance of the diagnostic-therapeutic pathways of LC pts.

How covid-19 pandemic impacted integrated care pathways for lung cancer: the experience of two Italian centers in veneto region

Background: COVID-19 pandemic has represented a historic challenge to healthcare systems. The management of cancer care has become a crucial issue for clinical services to cancer patients. During the COVID-19 pandemic, raising evidence has been published on lung cancer care but no data have been presented on the integrated care pathways (ICP) impact. Materials and methods: We retrospectively reviewed the ICPs of consecutive lung cancer patients who accessed two Centres before and after COVID-19 pandemic: the Veneto Institute of Oncology (IOV)/University Hospital of Padua and University Hospital of Verona. Sixteen indicators about oncology, radiaton therapy, thoracic surgery, pathology and pneumology were developed using groupfacilitation techniques taking into account their reproducibility, significance, measurability. We report data extracted from electronic medical records and linked softwares, about MDT performance at the two participating Centres, and preliminary data about pathological and oncological indicators in Padua. Additional data about both complete ICPs will be presented at the Conference. Results: We compared data about ICP performance in two window periods: 1/3/2019-30/4/2019 and 1/3/2020- 30/4/2020. MDT meetings were reshaped in order to discuss those cases where more than two specialists were required and whenever possible on a web-basis;therefore, it determined an average reduction of patients discussed of 57.5%. Preliminary data from Padua showed that median time between diagnostic procedure and diagnosis was reduced from 11 days in 2019 to 7.5 days in 2020, mostly due to a prioritization of oncological procedures over any other. Moreover, a 39% reduction of first oncological visits was observed between the two time frames;this was linked to a reduction of out of region second opinion and to optimization of outpatient access. Among patients under oncological treatment, 12(4%) and 8(2%) patients received treatment within 30 days from death in 2019 and 2020, respectively. Conclusions: Based on the experience the two Centres went through, we identified the key steps in ICP impacted by a pandemic such COVID-19 so to proactively put in place robust service provision in thoracic oncology.
