Background Cancer patients are thought to have an increased risk of developing severe Coronavirus Disease 2019 (COVID-19) infection and of dying from the disease. In this work, predictive factors for COVID-19 severity and mortality in cancer patients were investigated. Patients and Methods In this large nationwide retro-prospective cohort study, we collected data on patients with solid tumours and COVID-19 diagnosed between March 1 and June 11, 2020. The primary endpoint was all-cause mortality and COVID-19 severity, defined as admission to an intensive care unit (ICU) and/or mechanical ventilation and/or death, was one of the secondary endpoints. Results From April 4 to June 11, 2020, 1289 patients were analysed. The most frequent cancers were digestive and thoracic. Altogether, 424 (33%) patients had a severe form of COVID-19 and 370 (29%) patients died. In multivariate analysis, independent factors associated with death were male sex (odds ratio 1.73, 95%CI: 1.18-2.52), ECOG PS ≥ 2 (OR 3.23, 95%CI: 2.27-4.61), updated Charlson comorbidity index (OR 1.08, 95%CI: 1.01-1.16) and admission to ICU (OR 3.62, 95%CI 2.14-6.11). The same factors, age along with corticosteroids before COVID-19 diagnosis, and thoracic primary tumour site were independently associated with COVID-19 severity. None of the anticancer treatments administered within the previous 3 months had any effect on mortality or COVID-19 severity, except cytotoxic chemotherapy in the subgroup of patients with detectable SARS-CoV-2 by RT-PCR, which was associated with a slight increase of the risk of death (OR 1.53; 95%CI: 1.00-2.34; p = 0.05). A total of 431 (39%) patients had their systemic anticancer treatment interrupted or stopped following diagnosis of COVID-19. Conclusions Mortality and COVID-19 severity in cancer patients are high and are associated with general characteristics of patients. We found no deleterious effects of recent anticancer treatments, except for cytotoxic chemotherapy in the RT-PCR-confirmed subgroup of patients. In almost 40% of patients, the systemic anticancer therapy was interrupted or stopped after COVID-19 diagnosis.

After a mean follow-up period of 6.5 years, 15 patients were still using their device. Each patient had an average improvement of 33 ± 7 dB. Closure of the ABG within 15 dB of the preoperative bone-conduction thresholds occurred in 10 patients. Adverse skin reactions appeared in 50% of patients over 6.5 years of follow-up. Eleven of the 12 patients used their BAHA for more than 8 h per day.

The addition of cetuximab (CTX) to the combination of cisplatin and 5-fluorouracil increases the overall survival (OS) in recurrent/metastatic head and neck squamous cell carcinoma. Only a few patients are eligible for this treatment because of its toxicity. The combination of CTX and paclitaxel (TXL) could be included in sequential treatment strategies. Patients were treated with CTX (400/250 mg/m) and TXL (60-80 mg/m) weekly until disease progression or unacceptable toxicity. Efficacy and safety outcomes were determined retrospectively. A total of 42 patients were included in this analysis. The overall response rate was 38% [95% confidence interval (CI); 23-53%]. The disease control rate with TXL and CTX combination was 74%. Seven (17%) patients progressed before the first evaluation. The median progression-free survival was 3.9 months [95% CI; 3.1-4.7 months] and the median OS was 7.6 months [95% CI; 5.3-9.9 months]. Neurotoxicity and skin rash were the most frequent grade≥2 toxicities, reported in 17 and 12% of patients, respectively. Previous chemotherapy seems to be associated with a lower response rate and progression-free survival but not with the OS. The combination of CTX and TXL was an active and well-tolerated treatment in this series of patients with a poor prognosis and who were mostly symptomatic.

According to the high morbimortality, it is important to carefully select the right patients for surgery.

Five patients (45%) had a local recurrence and died from their recurrence. Three had a premature recurrence, just before or during radiotherapy. We could not determine the prognostic factors for overall survival and progression-free survival.
