RESUMEN
Background: During the Omicron variant outbreak of COVID-19 (2022-2023), Chinese healthcare institutions combined traditional Chinese medicine (TCM) with Western medical practices to treat COVID-19 patients, especially the elderly. The efficacy and safety of this approach, especially for individuals aged over 85, need further investigation. Methods: In this retrospective study, a cohort of 62 patients aged over 85 years, diagnosed with COVID-19 infection, was examined. Among them, 34 patients were administered Shashen-Maidong decoction in conjunction with Western medicine (SMD+WM group), while the remaining 28 patients received only Western medicine (WM group). Comparative analysis was conducted between the two groups, encompassing parameters such as the duration for the nucleic acid test to turn negative, length of intensive care unit (ICU) stay, mortality rate, utilization of high-flow nasal cannula oxygen (HFNC), occurrence of endo-tracheal intubation, frequency of recurrent respiratory infections within three months, and various laboratory indicators. Results: There were no significant differences observed between the two groups in terms of the duration for the nucleic acid test to turn negative, the length of ICU stay, mortality rate, utilization of HFNC, performance of endo-tracheal intubation, or the frequency of recurrent respiratory infections within three months (P > 0.05). However, in comparison to the WM group, the SMD+WM group exhibited notably lower growth rates in white blood cell (WBC) and neutrophil (NEUT) values. Additionally, the SMD+WM group demonstrated superior improvement in cardiac troponin I (cTnI) and B-type natriuretic peptide (BNP) values. Conclusion: In contrast to the administration of Western medicine alone, the combined use of Shashen-Maidong decoction with Western medicine significantly suppresses the increase in WBC count, particularly in NEUT levels, in elderly patients diagnosed with COVID-19. Moreover, this combined treatment exhibits a protective effect on cardiac function and demonstrates a relatively safe profile.
RESUMEN
Background: Cardiotoxicity associated with the sequential use of anthracyclines followed by trastuzumab is common in adjuvant therapy of patients with HER2-positive early breast cancer (eBC). However, the cardiac safety of trastuzumab concurrent with pegylated liposomal doxorubicin (PLD) is relatively less studied. Method: Clinical data of patients with HER2-positive eBC treated with PLD and cyclophosphamide (PLD-C) followed by taxanes plus trastuzumab ± pertuzumab (TH or TPH) who then completed standard anti-HER2 treatment for 12 months from June 2012 to August 2021 were retrospectively collected. The primary endpoints were clinical and subclinical cardiotoxicity. Result: In total, 70 eligible patients were enrolled. Among them, 55 patients (78.6%) received PLD-C â TH and 15 patients (21.4%) received PLD-C â TPH. The median follow-up time was 41.8 months. Until August 2021, only two patients had recurrent or metastatic diseases, with 2-year and 5-year disease-free survivals of 98.6% and 96.8%, respectively. Clinical cardiotoxicity occurred in six patients (8.6%), and all of them had an absolute decline of ≥16% from baseline left ventricular ejection fraction (LVEF) but not below the lower limit of normal (LLN = 50%). Subclinical cardiotoxicity events occurred in 17 patients (24.3%), and all of them had absolute declines of ≥10% and <16% from baseline LVEF but not below the LLN. No patients were interrupted from treatment, and all patients completed anti-HER2 treatment for 12 months. The sharpest decrease in LVEF was observed at 18 months after the start of PLD treatment. The cumulative incidences of clinical and subclinical cardiotoxicity were 9.8% and 28.3%, respectively. In the univariate analysis, body mass index, age, left chest wall radiotherapy, and ongoing cardiovascular risk factors were not significantly associated with clinical or subclinical cardiotoxicity (p > 0.05). No patients had congestive heart failure or death caused by PLD or anti-HER2 treatment. Conclusion: The sequential use of PLD and trastuzumab showed a lower incidence of clinical cardiotoxicity, presented as asymptomatic decreased LVEF, compared with the results obtained in previous clinical studies using conventional anthracycline, taxanes and trastuzumab. The study regimen demonstrated good cardiac tolerance and is an alternative strategy for cardioprotection in patients with HER2-positive eBC.
RESUMEN
Background: Salivary duct carcinoma (SDC), an aggressive and rare malignancy with poor prognosis, is mostly associated with the overexpression of the androgen receptor (AR) and human epidermal growth factor receptor 2 (HER2). However, limited data are available for the targeting of both HER2 and AR in advanced/metastatic SDC. Case Presentation: A 62-year-old man with advanced SDC accompanied by lung and lymph node metastasis showed disease progression after two lines of chemotherapy and endocrine therapy. Metastatic lesions from the lung biopsy were obtained, and immunohistochemistry (IHC) indicated the overexpression of AR and HER2 (3+). The patient was administered pyrotinib (a pan-ErbB receptor tyrosine kinase inhibitor) and bicalutamide (an androgen receptor antagonist) as a third-line treatment. During the ten months of follow-up, a durable partial response was achieved with this combination. Conclusions: This is the first clinical study to report the successful application of pyrotinib in a patient with advanced SDC. We recommend that pyrotinib and bicalutamide be used as salvage therapy for AR and HER2-positive advanced metastases in SDC, given the favorable response and clinical benefit.
