Thyroid diseases in women with breast cancer
Several studies have been undertaken to investigate a possible link between breast cancer and thyroid diseases, notably thyroid carcinoma and autoimmune thyroid diseases, but the issue remains unresolved. The aim of this study is to evaluate, in thyropathic women with and without breast cancer, the following effects: the distribution of different thyroid diseases, the breast-cancer-related prevalence of anti-thyroperoxidase and anti-thyroglobulin antibodies and the role in thyroid pathology of breast-cancer post-surgery therapy with tamoxifene. One-hundred-ninety thyropathic women with breast cancer (BC group) were recruited, and compared with a control group (C group) of one-hundred-ninety thyropathic women without breast cancer. Nodular disease is the most frequent pathology in both groups. The difference in the incidence of thyroid carcinoma is also not statistically significant. The biochemical increase in the positivity of autoantibodies in BC-group patients is confirmed, but there is no statistically significant difference in the rate of clinical autoimmune diseases between the two groups. No difference in the frequency of any particular thyroid disease is found between those patients who underwent post-operative tamoxifene therapy and those who did not. It can be concluded, on the basis of these results, that it is advisable to reduce the clinical weight of the issue. A routine thyroid screening is recommended in women with BC for the management of chronic comorbidities, as would be for women in the general population having the same age and coming from the same iodine-intake area
Symptomatic COVID-19 in advanced-cancer patients treated with immune-checkpoint inhibitors: prospective analysis from a multicentre observational trial by FICOG
Background:This prospective, multicentre, observational INVIDIa-2 study is investigating the clinical efficacy of influenza vaccination in advanced-cancer patients receiving immune-checkpoint inhibitors (ICIs), enrolled in 82 Italian centres, from October 2019 to January 2020. The primary endpoint was the incidence of influenza-like illness (ILI) until 30 April 2020. All the ILI episodes, laboratory tests, complications, hospitalizations and pneumonitis were recorded. Therefore, the study prospectively recorded all the COVID-19 ILI events.Patients and methods:Patients were included in this non-prespecified COVID-19 analysis, if alive on 31 January 2020, when the Italian government declared the national emergency. The prevalence of confirmed COVID-19 cases was detected as ILI episode with laboratory confirmation of SARS-CoV-2. Cases with clinical-radiological diagnosis of COVID-19 (COVID-like ILIs), were also reported.Results:Out of 1257 enrolled patients, 955 matched the inclusion criteria for this unplanned analysis. From 31 January to 30 April 2020, 66 patients had ILI: 9 of 955 cases were confirmed COVID-19 ILIs, with prevalence of 0.9% [95% confidence interval (CI): 0.3-2.4], a hospitalization rate of 100% and a mortality rate of 77.8%. Including 5 COVID-like ILIs, the overall COVID-19 prevalence was 1.5% (95% CI: 0.5-3.1), with 100% hospitalization and 64% mortality. The presence of elderly, males and comorbidities was significantly higher among patients vaccinated against influenza versus unvaccinated (p = 0.009, p < 0.0001, p < 0.0001). Overall COVID-19 prevalence was 1.2% for vaccinated (six of 482 cases, all confirmed) and 1.7% for unvaccinated (8 of 473, 3 confirmed COVID-19 and 5 COVID-like), p = 0.52. The difference remained non-significant, considering confirmed COVID-19 only (p = 0.33).Conclusion:COVID-19 has a meaningful clinical impact on the cancer-patient population receiving ICIs, with high prevalence, hospitalization and an alarming mortality rate among symptomatic cases. Influenza vaccination does not protect from SARS-CoV-2 infection
