Objective To investigate the diagnosis and treatment methods of primary cardiac malignant tumors，so as to improve its’ level of diagnosis and treatment. Methods From April 2004 to June 2008, 19 patients with primary cardiac malignant tumors were diagnosed and treated in the department of cardiac surgery in this hospital. Male 11, Female 8.Age of the patients was 40.7±12.1 years(17-64 years). Preoperative diagnosis were occupying lesion in cardiac, malignant tumors were possible. Complete resections of malignant tumors were achieved by cardiopulmonary bypass (CPB) in 3 cases, and partially resected in 1 case, heart transplantation was performed in 1 case, only biopsies were performed in 5 cases. 9 cases (47.4%) lost the chances of operative treatments. Results There were no operative and hospitalstay deaths. Hospital stay was 10±7 d（9-15 d）, all patients were safely discharged from hospital. Two cases suffered from postoperative pericardial effusions，and high temperature happened in 1 patient, these 3 cases recovered by puncture and symptomatic treatment. The pathological diagnosis: leiomyosarcoma in 1case, malignant mesothelioma in 1 case and hemangioendothelial sarcoma in 8 cases. 14 cases (73.7%) were followed up from 1 to 38 months, 14 cases died of tumor recurrence or metastasis, the mortality was 73.7%, 5 cases (26.3%) were failed to be followed up. Conclusion The prognosis of patient with primary cardiac malignant tumor is still poor. Earlier diagnosis and complete surgical removal of the tumor as soon as possible may improve the patients’qualities of lives.
ObjectiveTo observe the clinical and imaging features of infiltrative optic neuropathy (ION) secondary to extraocular malignant tumors. MethodsA retrospective case study. From January 2017 to October 2022, 26 eyes of 20 patients with ION secondary to extraocular malignancies and 32 eyes of 16 patients with early papilloedema (EP) secondary to intracranial metastatic carcinoma were included in the study. All eyes underwent best corrected visual acuity (BCVA), fundus color photography, orbital and/or craniocerebral magnetic resonance imaging (MRI). A total of 54 eyes were examined by visual field examination, among which ION and EP were 22 and 32 eyes, respectively. Clinical and imaging features of the affected eye were retrospectively analyzed. ResultsAmong 26 eyes of 20 ION patients, there were 13 males and 7 females, with the mean age of (52.8±16.9) years. There were 10 patients of hematologic malignancy, 7 patients of periorbital malignancy, 2 patients of lung cancer, 1 patient of gastric cancer, 1 patient of breast cancer and 1 patient of prostate cancer. Two patients of nasal lymphoma were recorded as hematologic malignancies and periorbital malignancies. Sixteen patients had a history of systemic or periorbital malignancy, among which 4 patients reported that they had been "clinically cured". Optic neuritis was diagnosed in 15 patients. Among the 16 patients with EP, 5 were males and 11 were females, with the mean age of (47.9±12.3) years. The primary malignant tumors were lung cancer, breast cancer, leukemia, gastric cancer, ovarian cancer, colon cancer and rectal cancer in 7, 2, 2, 2, 1, 1, 1, respectively. In 26 eyes of ION, 20 eyes complained of blurred vision or peripheral vision occlusion and progressive aggravation; no obvious visual symptoms in 6 eyes. BCVA was light sensing to 1.0 with a median of 0.3, including light sensing and light sensing in 4 eyes. Optic disc edema was observed in 19 eyes; no obvious abnormality in 7 eyes. Visual field examination showed that in 22 eyes, normal or mild enlargement of blind spot in 3 eyes, arcuate scotoma in 4 eyes, annular scotoma in 6 eyes, tubular visual field or concentric contraction of visual field in 6 eyes, and diffuse depression in 3 eyes. MRI showed optic nerve enlargement with sheath enhancement in all ION eyes. Among 32 eyes of EP, 28 eyes showed recurrent transient amaurosis, and the other 4 eyes showed horizontal diplopia. BCVA ranged from 0.8 to 1.5, with a median of 1.0. All EP patients showed different degrees of optic disc hyperemia and edema by fundus examination. The visual field examination showed normal or mild enlargement of the physiological blind spot. MRI showed thickening of the optic nerve and widening of the intrathecal space, but no obvious enhancement of the optic nerve and its intrathecal membrane, and obviously enhanced space-occupying lesions in the brain parenchyma, accompanied by compression and edema of the surrounding brain tissue and midline displacement. ConclusionsION secondary to extrocular malignant tumors mainly manifested as mild visual symptoms and obvious optic disc edema. MRI showed thickened optic nerve and strengthened sheath, and no obvious abnormality in optic nerve parenchyma.
ObjectiveTo systematically evaluate the efficacy and safety of autologous natural killer cells (NK) cells for the treatment of malignant tumors. MethodsThe PubMed, Web of Science, and Embase databases were electronically searched to collect clinical studies on autologous NK cells for the treatment of malignant tumors from inception to July 1, 2023. Two reviewers independently screened literature, extracted data and assessed the risk of bias of the included studies. Descriptive analysis of the results were conducted. ResultsA total of 15 studies were included. The most common tumor type was non-small cell lung cancer. The dose of NK cell injections usually ranged from 7.0×107 to 7.0×109 cell counts, with a treatment interval of 14-21 days and a frequency of 3-6 injections. The overall response rate for NK cell therapy was 0% to 77.78%. The main adverse effects were fever (3.98%), fatigue (1.99%), rash (0.4%), and dizziness (1.20%). ConclusionCurrent evidence shows that autologous NK cell therapy is safe for malignant tumors, and some studies have shown that NK cell therapy has a relieving effect. However, due to limitations in the number and quality of studies included, the above conclusions come from a qualitative synthesis of individual studies and need to be validated by more high-quality studies.
