Resumen
Various measures of immune response were assessed prior to induction chemotherapy (intravenous [IV] cisplatin, fluorouracil [5-FU], and bleomycin) in 43 previously untreated head and neck cancer patients to derive a clinical response prediction model. These were parameters of functional cellular immunity (natural killer [NK] cell activity, lymphocyte blastogenesis response to mitogens), total lymphocyte and lymphocyte subset numbers and percentages, and circulating humoral immunity (total immunoglobulin, immunoglobulin classes, and C1q binding activity [C1q BA]). The C1q BA may reflect levels

Objective.To study the state of cellular immunity and local immunity in patients with gastric adenocarcinoma.Materials and methods.From 2017 to 2018 45 primary patients with gastric adenocarcinoma (25 — with stages I–III, 20 — with stage IV) received surgical / combined treatment or chemotherapy at the Blokhin Scientific Research Center of Oncology, respectively. Peripheral blood and tumor tissue were collected before starting treatment. The percentage of the degree of infiltration of tumor tissue by lymphocytes (CD45 + CD14‑TILs) was assessed by flow cytometry: T‑cells (CD3 + CD19‑TILs), B‑ce

Resumen
Hepatocellular carcinoma (HCC) still represents a significant complication of chronic liver disease, particularly when cirrhosis ensues. Current treatment options include surgery, loco-regional procedures and chemotherapy, according to specific clinical practice guidelines. Immunotherapy with check-point inhibitors, aimed at rescuing T-cells from exhaustion, has been applied as second-line therapy with limited and variable success. Natural killer (NK) cells are an essential component of innate immunity against cancer and changes in phenotype and function have been described in patients with HC

Resumen
e16082 Background: Clonal hematopoiesis (CH) represents non-random clonal selection of bone marrow-derived cells marked by somatic mutations in certain genes. The presence of CH is associated with development of atherosclerosis and leukemia, and accelerated by toxic exposures (chemotherapy, radiation, smoking) and aging (Jaiswal et al. NEJM 2017; Abelson et al. Nature 2018). The impact of these genetic alterations on cellular function is unknown, especially in the broader context of immunity and in response to cancer therapy. To determine the contribution of CH to therapeutic response and hema

We hypothesized that non-small cell lung cancer (NSCLC) patients with higher numbers of circulating CD34+ endothelial progenitor cells (CD34+/CD146+/CD45-, CEC) would have worse post-treatment outcomes and patients with more hematopoietic progenitor cells (CD34+/CD45+/CD45dim/CD133+, HPC) would have better outcomes. Methods: Blood samples from patients with advanced NSCLC were analyzed at 3 time points: prior to chemotherapy, after cycle one, and at completion of treatm

Resumen
Cryosurgery used on patients with unresectable pancreatic cancer improved their quality of life, but mainly because of the pain relief. In postoperative patients, multifaceted changes in immunity were found, and the state of the immune system prior to surgery often was a decisive factor to indicate whether further disorders in the postoperative period would develop, or by contrast, it would boost its recovery. Some patients receiving cryosurgery showed immune system imbalance and activation, and of antitumor immunity in particular. It has been suggested that the advisability of immunotropic th

Resumen
Chemotherapy is one of most significant therapeutic approaches to cancer. Immune system functional state is considered a major prognostic and predictive impact on the success of chemotherapy and it has an important role on patients’ psychoemotional state and quality of life. In Chinese medicine, chemotherapy is understood as “toxic cold” that may induce a progressive hypofunctional state of immune system, thus compromising the fast recovery of immunity during chemotherapy. In this study, we performed a standardized acupuncture and moxibustion protocol to enhance immunity in cancer patients und

Resumen
Cellular Immunity in Human Herpes Viruses 6 and 7 Infected Gastrointestinal Cancer Patients CD4+ T lymphocytes appear to be the preferential target for replication of HHV-6 (human herpes virus) as well as HHV-7 viruses in vivo. In addition, CD8+ T cells, monocytes/macrophages, natural killer cells, epithelial, endothelial, neural cells and fibroblasts may be infected. By definition, however, even a tumour designated by pathologists to be early stage may be late stage when considered by the immune system. Certainly, even early stage tumours have evaded immune control, suggesting that they have
