The impact of cancer metastases on COVID-19 outcomes: A COVID-19 and Cancer Consortium registry-based retrospective cohort study.

BACKGROUND: COVID-19 can have a particularly detrimental effect on patients with cancer, but no studies to date have examined if the presence, or site, of metastatic cancer is related to COVID-19 outcomes. METHODS: Using the COVID-19 and Cancer Consortium (CCC19) registry, the authors identified 10,065 patients with COVID-19 and cancer (2325 with and 7740 without metastasis at the time of COVID-19 diagnosis). The primary ordinal outcome was COVID-19 severity: not hospitalized, hospitalized but did not receive supplemental O2, hospitalized and received supplemental O2, admitted to an intensive care unit, received mechanical ventilation, or died from any cause. The authors used ordinal logistic regression models to compare COVID-19 severity by presence and specific site of metastatic cancer. They used logistic regression models to assess 30-day all-cause mortality. RESULTS: Compared to patients without metastasis, patients with metastases have increased hospitalization rates (59% vs. 49%) and higher 30 day mortality (18% vs. 9%). Patients with metastasis to bone, lung, liver, lymph nodes, and brain have significantly higher COVID-19 severity (adjusted odds ratios [ORs], 1.38, 1.59, 1.38, 1.00, and 2.21) compared to patients without metastases at those sites. Patients with metastasis to the lung have significantly higher odds of 30-day mortality (adjusted OR, 1.53; 95% confidence interval, 1.17-2.00) when adjusting for COVID-19 severity. CONCLUSIONS: Patients with metastatic cancer, especially with metastasis to the brain, are more likely to have severe outcomes after COVID-19 whereas patients with metastasis to the lung, compared to patients with cancer metastasis to other sites, have the highest 30-day mortality after COVID-19.

Evaluation of irinotecan plus paclitaxel in patients with advanced non-small cell lung cancer.

PURPOSE: We conducted a phase II study to evaluate the efficacy and safety of the combination of irinotecan and paclitaxel in patients with advanced stage non-small cell lung cancer (NSCLC). PATIENTS AND METHODS: Patients were eligible if they had histologically confirmed chemotherapy naïve stage IV NSCLC or stage IIIB disease that was not suitable for combined modality therapy. Patients were treated with irinotecan 50 mg/m2 and paclitaxel 75 mg/m2 on days 1 and 8 of a 21-day cycle. If the patient did not experience >grade 1 toxicity during the first cycle, the dose of irinotecan could be escalated to 60 mg/m(2). Patients were evaluated for tumor response rate, time to progression (TTP), overall survival (OS) and toxicity. RESULTS: Twenty-three eligible patients were treated. Two (9%) patients achieved a partial response. Eight patients (35%) had stable disease. The median number of cycles given per patient was four (range 1-29). The major toxicities were grade >or=3 neutropenia (26%) and grade 3 diarrhea (5%). The median time to progression was 2.8 months (range 0.5-21.8 months) for all patients and 4.3 months for the patients who had either stable disease or a partial response. The median overall survival was 9.2 months (range 0.5-40 months). The one- and two-year survival rates were 39% and 13%, respectively. CONCLUSION: The combination of irinotecan and paclitaxel is safe in advanced NSCLC and affords a survival similar to other non-platinum as well as platinum-based doublets. However, this combination does not have sufficient activity to justify further study in an unselected population. If biomarkers are developed that can guide the selection of chemotherapy in an individual patient, there may be a rationale for further evaluation of this regimen.
