Abstract The objective of this document is to formalize a degraded mode management for patients with thoracic cancers in the context of the COVID-19 pandemic. The proposals are based on those of the French High Council for Public Health, on published data outside the context of COVID-19, and on a concerted analysis of the risk-benefit ratio for our patients by a panel of experts specialized on thoracic oncology under the aegis of the French-Language Society of Pulmonology (SPLF) / French-language oncology group. These proposals are evolving (10/04/2020) according to the situations encountered which will enrich it, and are to be adapted to our institutional organisations and to the evolution of resources during the COVID-19 epidemic. Patients with symptoms and/or COVID-19+ are not discussed in this document and are managed within the framework of specific channels.

This document aims to formalize a minimum level of management for patients with thoracic malignancies during the COVID-19 pandemic. The objectives are to reduce the risk of infection among particularly vulnerable patients and save human medical and paramedical resources as well as material resources like operating theaters, ventilators and hospital beds. The goal is to handle thoracic cancer patients in a concerted and, above all, in a standardized manner. These proposals may be updated (04/10/2020) as situations arise and are incorporated into them. They must be tailored to our institutions and fluctuating resources during the COVID-19 epidemic. The proposals are based on those of the French High Council for Public Health, on published data on thoracic oncology outside the context of COVID-19, and on a concerted analysis of the risk-benefit ratio for our patients. They were elaborated by email exchanges between all the authors and, for a few points a consensus was settled by phone calls with several of them. Symptomatic and/or COVID-19+ patients are not discussed in this document. They are managed by specific departments.

Patients are to come to appointments for treatment purposes only once they receive confirmation the day before through remote consultation. On arrival on the day of their appointment, they are checked for any fever and/or symptoms that might have appeared since the previous day and then enter the treatment and follow-up units unaccompanied. If they have symptoms, they will be referred to a specific COVID unit.

Patients in other situations will be seen through remote consultation. Whenever possible, home hospital care should be the preferred option. Patients with metastatic or locally advanced lung cancer are at risk of serious infection because they may be immunocompromised (corticosteroids, chemotherapy) or suffer from concomitant lung disease or ischemic heart disease. Healthcare personnel are exposed to greater social contact in the hospital. As with other immunocompromised patients, if visits by lung cancer patients to outpatient services cannot be avoided, the following measures must be taken:

double-barrier protection: when patients enter the unit, they must be given a surgical mask which they must wear throughout their stay.

healthcare personnel must wear a surgical mask throughout the day (1 mask/4 hours).

healthcare personnel must repeatedly disinfect their hands using an alcoholbased solution. The diaphragms of stethoscopes and sensors of pulse oxymeters must also be disinfected using an alcohol-based solution or alcohol wipes.

The patient's healthcare wishes must be discussed with the patient and recorded in the medical file.

These patients receive curative treatment. Their survival rate is more than 50% at 5 years [1] . proposed that surgical resection be postponed for stage I and even some stage II N0 tumors, either by putting surgery off (for up to 6 weeks) or by offering stereotactic radiotherapy as a treatment alternative with a reduced number of sessions (1 to 3) to limit the number of visits patients need to make. This will depend on the limited availability of this technique during the lockdown period. We suggest that bronchoscopy not be performed in patients whose surgery is postponed as outlined above. Finally, for patients about to undergo surgery, a systematic screening for COVID by viral PCR and a systematic chest CT scan are discussed in order to avoid operating on asymptomatic COVID patients.

Patients currently undergoing treatment will finish their course. Given the uncertainty surrounding the utility of radiotherapy in this setting, no new patient is to begin adjuvant radiation treatment for pN2 disease. 

These patients receive curative treatment. Their survival rate is more than 50% at 3 or even 5 years [2] . These patients are known to be more at risk of developing severe respiratory complications requiring critical care. Patients currently undergoing treatment will finish their course. For patients currently undergoing chemotherapy, carboplatin is preferable to cisplatin since it is faster to administer and has lower toxicity. Regarding patients currently on durvalumab, the proposal being considered is 1/ double the dose to 1500mg once every 4 weeks or 2/ space administration out to once every 4 weeks. Initiating treatment in new patients must be discussed in MDT meetings. Since consolidation with durvalumab offers significant survival benefit, treatment must be administered if reasonable safety conditions can be met.

These patients receive palliative care. Their survival rate is more than 50% at 3 or even 5 or 7 years [3] . The general plan is to continue any targeted therapy currently being Some of these treatments may have cytopenic effects. Care must be taken to monitor CBCs, particularly regarding neutropenia.

These patients are known to be more at risk of developing severe respiratory complications requiring critical care. These patients receive palliative care. Their survival rate is around 50% at 2 years [4] .

For patients who are currently receiving treatment:

-Induction immunotherapy +/-chemotherapy: patients currently receiving treatment finish their course up to 4 cycles.

-Maintenance chemotherapy: the risk-benefit ratio will be assessed case-bycase so that we can propose either spacing out or discontinuing maintenance therapy.

-Pembrolizumab immunotherapy: it is proposed 1/ that administration be halted in responders who have been on treatment for more than 1 year, and 2/ that the dose of Pembrolizumab be doubled to 400mg once every 6 weeks after the initial assessment in patients with controlled disease who are in their first year of treatment.

The administration interval of immunotherapy may be doubled and the dose administered at each treatment doubled or space administration out to once every 6

weeks. If an initial assessment after 2 months of treatment confirms a response or tumor control, assessments need only be performed once every 4 months. However, J o u r n a l P r e -p r o o f 9 a remote consultation and lab tests must be conducted every month. Any sign of toxicity, such as colitis or lung disease, requires the patient to be called in and hospitalized.

Initiating treatment in new patients must be discussed in MDT meetings.

These patients are known to be more at risk of developing severe respiratory complications requiring critical care. These patients receive palliative care. Their median survival is around 1 year [5] .

For patients who are currently receiving treatment:

-Chemotherapy: discuss the appropriateness of continuing treatment.

-Immunotherapy: it is proposed 1/ that administration be halted in responders who have been on treatment for more than 1 year, and 2/ that doses be doubled in patients with stable disease who are in their first year of treatment: Nivolumab to 480mg every 4 weeks, and Pembrolizumab to 400mg every 6 weeks after initial assessment. Atezolizumab could be administered at 1200mg every 4 (unstead of 3)

weeks [6] .Initiating further lines of treatment must be discussed in MDT meetings. 

These patients are known to be more at risk of developing severe respiratory complications requiring critical care. These patients receive palliative care. Their median survival is around 1 year [8] .

First-line and ongoing treatments must be continued. Initiating treatment in new patients must be discussed in MDT meetings. Second-line and ongoing treatments must be continued. Initiating further lines of treatment must be discussed in MDT meetings. Atezolizumab must be offered according to the recommendations in the current extended Temporary Authorization for Use, particularly regarding PS criteria.

However, Atezolizumab could be administered at 1200mg every 4 (unstead of 3)

weeks [6] . More recently, Durvalumab also obtained its Temporary Authorization for Use in this indication.

Carboplatin is preferable to cisplatin since it is faster to administer and has lower toxicity. G-CSF growth factors must be administered in all cases.

J o u r n a l P r e -p r o o f 11

These patients are known to be more at risk of developing severe respiratory complications requiring critical care. These patients receive palliative care. Their median survival is between 15 and 18 months [9] .

First-line and ongoing treatments must be continued. Initiating treatment in new patients must be discussed in MDT meetings. Ongoing second-line treatments must be continued. Initiating further lines of treatment must be discussed in MDT meetings.

Immunotherapy: it is proposed 1/ that administration be halted in responders who have been on treatment for more than 1 year, and 2/ that doses be doubled after the initial assessment in patients in their first year of treatment (Nivolumab to 480mg every 4 weeks). Bevacizumab maintenance therapy may be halted.

These patients are known to be more at risk of developing severe respiratory complications requiring critical care, particularly in cases of concomitant myasthenia gravis.

Complex situations should be discussed with the coordinating physician from the RYTHMIC thymic malignancy network. For example, one proposal is to discuss cases and their urgency in MDT meetings. The discussion should focus on the size of the tumor, histological type and general health of the patient. Another proposal is to postpone surgical resection of stage I and stage II tumors. Ongoing first-line treatments must be continued. Initiating treatment in new patients must be discussed in MDT meetings. Ongoing second-line treatments must be continued. Initiating further lines of treatment must be discussed in MDT meetings.

Situation should be examined case-by-case depending on the study and type of patients involved. A clear benefit and rare settings with no treatment alternatives must be prioritized. Special attention should be paid to trials in neoadjuvant settings or involving chemoradiotherapy in which access to surgery or radiotherapy on a particular date is not guaranteed.
