Purpose To evaluate the clinical characteristics and outcomes of critically ill patients with testicular cancer (TC) admitted to an oncological intensive care unit (ICU). Methods This was a prospective observational study. There were no interventions. Results During the study period, 1,402 patients with TC were admitted to the Department of Oncology, and 60 patients (4.3%) were admitted to the ICU. The most common histologic type was nonseminomatous germ cell tumors (55/91.7%). The ICU, hospital, and 6-month mortality rates were 38.3%, 45%, and 63.3%, respectively. The Cox multivariate analysis identified the white blood cells count (HR = 1.06, 95% CI = 1.01–1.11, and P = 0.005), ionized calcium (iCa) level (HR = 1.23, 95% CI = 1.01–1.50, and P = 0.037), and 2 or more organ failures during the first 24 hours after ICU admission (HR = 3.86, 95% CI = 1.96–7.59, and P < 0.001) as independent predictors of death for up to 6 months. Conclusion The ICU, hospital, and 6-month mortality rates were 38.3%, 45%, and 63.3%, respectively. The factors associated with an increased 6-month mortality rate were white blood cells count, iCa level, and 2 or more organ failures during the first 24 hours after ICU admission.

Keratinocyte cancer (KC) is the most common form of cancer in humans. To our knowledge, no previous publications assessing the methodological quality of clinical trials for the prevention of KC have been recently published. We aim to assess the methodological quality of clinical trials focused on the prevention of KC in high-risk groups not receiving immunosuppressive therapy (NRIT) and propose solutions to improve the design of future trials. We searched clinical trials in which the main outcome was the prevention of KC in high-risk NRIT groups using the strategy published in the International Prospective Register of Systematic Reviews (PROSPERO registry), CRD42016045981. Consolidated Standards of Reporting Trials (CONSORT) criteria and the Cochrane Collaboration risk of bias tool were used to assess methodological quality. We analyzed 23 clinical trials. We found a high risk of attrition and reporting bias in 86.9% and 60.9% of the trials, respectively. Regarding the CONSORT criteria, in at least 40% of the trials, the authors omitted the following information: a description of the trial design, the number of losses and exclusions after randomization, the results of subgroup and adjusted analysis, the estimated effect size and the precision of primary and secondary outcomes. Methodological quality was improved in the recently published clinical trials compared to those published before the CONSORT criteria development. All clinical trials should report in detail the information used to assess potential risks of bias.
