Detection of CTCs and CSCs in the staging and metastasis of non-small cell lung cancer based on microfluidic chip and the diagnostic significance.

This study explores the diagnostic significance of microfluidic chip technology in the detection of CTCs/CSCs in clinical staging and metastasis of patients with non-small cell lung cancer (NSCLC). That lays a solid foundation for the use of microfluidic chips to monitor CTCs/CSCs for the stage and metastasis of patients with non-small cell lung cancer. PATIENTS AND METHODS: This study collected 80 patients with lung cancer from October 2017 to October 2018. Meanwhile, 30 healthy people and 30 patients with benign lung diseases were selected during the same period as the control group 1 and the control group 2, respectively. CellSearch (Huntington Valley, PA, USA) and microfluidic chip were used to detect CTCs, the sensitivities were recorded. ELISA methods were used to detect the concentrations of tumor markers VEGF-C, CEA, and CA125 in serum, and their association with CTCs and CSCs was analyzed. In addition, after 3 months, we followed up 40 patients with lung cancer, recorded their prognosis, and extracted peripheral blood to detect changes in their CTCs and CSCs. The CellSearch (Huntington Valley, PA, USA) system and the microfluidic chip system were used to detect the CTCs in patients with lung cancer, and the sensitivity and specificity of the patients were analyzed. The changes in CTCs and CSCs in the peripheral blood of the patient were recorded. RESULTS: It can be seen that the positive rate of CTCs and CSCs is not significantly correlated with the patients'...

ConclusionsThis systematic review suggests that women with HPV- and p16-positive vaginal cancer have an improved prognosis compared with those with HPV- or p16-negative vaginal cancer. Results for p53 were varied, and no conclusion could be reached. Only 12 studies could be included in the review, of which most were based on small populations. Hence, further and larger studies on the prognostic impact of HPV, p16, and p53 in vaginal cancer are warranted.

This study aims to detail the characteristics of chemotherapy-related acute kidney injury (CR-AKI) and investigate its effect on patient outcomes.MethodsThis is a multicenter cross-sectional study of cancer patients with CR-AKI screened from hospital-acquired adult AKI patients based on a nationwide AKI survey in China.ResultsOf the 3468 patients with hospital-acquired AKI, 258 cases of CR-AKI were identified. Of the patients, 20.1% (52/258) were ≥ 70 years old. Among the 258 CR-AKI cases, 61 (23.6%) reached AKI stage 3, and 75 (29.1%) reached AKI stage 2. The remaining 122 (47.3%) remained at AKI stage 1. A total of 41...

AbstractMethylation of N6-adenosine (m6A) is the most prevalent internal RNA modification and is especially common among the messenger RNAs. These m6A modifications regulate splicing, translocation, stability and translation of RNA through dynamic and reversible interactions with m6A-binding proteins, namely the writers, erasers and readers. RNA methyltransferases catalyze the m6A modifications, while demethylases reverse this methylation. Deregulation of the m6A modification process has been implicated in human carcinogenesis, including melanoma —which carries one of the highest mutant rates. In this review, we prov...

ConclusionPelvic floor dysfunction commonly deteriorates and negatively impacts on quality of life after minimally invasive radical hysterectomy, especially bowel function after TMMR. Pelvic floor symptoms should routinely be addressed pre- and postoperatively.

ConclusionsA better control of bladder filling is recommended to minimize the number of fractions in which the bladder volume is lower than planned. Fiducial mark tracking with a displacement threshold of 5  mm in any direction is recommended to ensure that the prescribed dose criteria are met.

AbstractCancer genomics has evolved over the years from understanding the pathogenesis of cancer to screening the future possibilities of cancer occurrence. Understanding the genetic profile of tumors holds a prognostic as well as a predictive value in this era of therapeutic surveillance, molecular remission, and precision medicine. Identifying molecular markers in tumors is the current standard of approach, and requires an efficient combination of an accessible sample type and a profoundly sensitive technique. Liquid biopsy or cell-free DNA has evolved as a novel sample type with promising results in recent years. Althou...

Conclusions and Future Perspectives It is now evident that NK/ILC family plays a pivotal role in the immune defenses. Recent studies in murine and human settings demonstrated that the expression of several inhibitory checkpoints, that may be detrimental in the tumor context, is not restricted to T lymphocytes, revealing an important, yet poorly appreciated, contribution of their expression on innate immune cells. Thus, in the recent years different immunotherapy approaches, based on the blockade of inhibitory NK cell receptors, have been developed in order to unleash NK cell cytotoxicity. This is particularly important in...

Conclusions MDSC are major players in the immunosuppressive scenario in cancer, thanks to their phenotype heterogeneity and critical interaction with several innate immune cells, thus representing a crucial target in oncology. Here we reviewed the interactions of MDSCs with NK cells. The contribution of key cytokines, chemokines and mediators active in this process have been discussed. We also described the contribution of MDSC on angiogenesis directly or indirectly through interactions with NK and immunosuppressive activities. A parallel of the cancer associated to the decidual counterpart of these cells is discussed, a...
