To analyze the prognosis of patients with breast cancer who developed trastuzumab-induced cardiotoxicity and to analyze factors associated with and resulting from cardiotoxicity.
This was a retrospective cohort study that included 255 HER2-positive breast cancer patients who received adjuvant trastuzumab therapy. The inclusion criteria were a diagnosis of HER2-positive breast cancer and adjuvant trastuzumab therapy; disease stage I-III; <70 years; and a baseline echocardiogram showing a left ventricular ejection fraction (LVEF) ≥ 55%. The Kaplan-Meier method, the log-rank test, and the Cox proportional hazards model were used.
In all, 15.3% (39/255) of patients presented with cardiotoxicity. Treatment was suspended in 92.3% (36/39) of patients who presented with cardiotoxicity during trastuzumab treatment. The treatment was suspended in 46 of 255 patients and it was permanently interrupted in 84.8% (33/46) of these patients, with 84.8% (28/33) due to cardiotoxicity. Cardiotoxicity was not associated with disease-free survival (DFS) (hazard ratio (HR) = 1.48; 95% confidence interval (CI = 0.79-2.78) or overall survival (OS) (HR = 1.68; 95%CI= 0.83-3.41). Patients with clinical stage III and whom trastuzumab therapy was suspended (all causes) had worse DFS; (HR = 3.19; 95% CI=1.77-5.74) and (HR = 1.83; 95% CI=1.01-3.32) respectively. Those with clinical stage III and whom trastuzumab therapy was permanently interrupted had worse OS; (HR = 3.80; 95% CI =1.82-7.94), and (HR = 2,26; 95% CI =1.09-4.68 respectively.
Cardiotoxicity was not associated with DFS or OS. Clinical stage III, Suspension and permanent interruption of treatment regardless of the cause were associated with worse DFS and OS in breast cancer patients.

To evaluate the role of being human immunodeficiency virus (HIV) positive for predicting the risk of recurrence in women with a cervical high grade squamous intraepithelial lesion (HSIL) diagnosis.
Retrospective observational case-control study, comprising HIV positive (case) and HIV negative (control) women in a 1:4 ratio. Women assisted by the Erasto Gaertner Hospital, between 2009-2018, with cervical HSIL diagnosis, submitted to treatment by Loop electrosurgical excision procedure (LEEP), and with a minimum follow-up of 18 months, were included. The immunological status, number and time to recurrence were analyzed, with p<0.05 considered significant. In a second analysis, only patients with free margins were evaluated.
The sample consisted of 320 women (64 cases and 256 controls). Presence of HIV, CD4 levels <200 and detectable viral load (CV) were associated with high risk of recurrence, with odds ratio (OR) of 5.4 (p<0.001/95CI:2.8-10); 3.6 (p<0.001 /IC95:0.6-21.1) and 1.8 (p=0.039 /IC95:0.3-9.3), respectively. In the sample with free margins (n=271), this risk was also higher among seropositive patients, with OR 4.18 (p=0.001/95CI:1.8-9.2).
HIV is an independent risk factor for cervical HSIL recurrence and reduced disease-free survival time. Glandular involvement, compromised margins, undetectable CV and CD4<200 also increase the risk of relapse.
