Effect of immunoadjuvants on the disease course in patients with operable breast cancer

Background. A new strategy of breast cancer management is required for effective disease prevention and control. Immunotherapy is one of promising options.Objective: to evaluate the effect of immunoadjuvant polyoxidonium on pathmorphological changes in breast tumors.Materials and methods. The study was performed in 75 patients with breast cancer: 50 patients received polyoxidonium in a neoadjuvant regimen (main group), 25 patients did not receive polyoxidonium (control group). Polyoxidonium at a dose of 12 mg was administered intramuscularly 1 time per day on the days 1, 2, 3, 5 and 7 before surgery; on the day 8, radical mastectomy was performed in patients of both groups, followed by histological examination and determination of the grade of therapeutic pathomorphosis of the tumor.Results. The proportion of cases with grade I therapeutic pathomorphosis was 58 %, grade II therapeutic pathomorphosis – 6 %. Pathomorphosis in metastatic lymph nodes was observed in 22.7 % of cases.Conclusion. The anti-tumor effect of polyoxidonium was confirmed on the basis of the induction of pathomorphosis of the tumor tissue of breast cancer.

The Impact ◽

Experimental Group

Purpose A cancer network of general or private hospitals of a French region was started in 1995 for improving quality of care and rationalizing medical prescriptions. The impact of implementing a clinical practice guidelines (CPG) project assessed conformity with guidelines in medical practice; significant changes were observed within the network, whereas no changes were observed in a control region without cancer network. In the present study, we evaluated the persistence of conformity to guidelines through a new medical audit. Patients and Methods In 1999, the hospitals of the previously compared experimental and control groups accepted to reassess the impact of CPG. A controlled transversal study was performed in the experimental group (cancer network) and in the control group (no regional cancer network). In 1996 (first audit) and in 1999 (present audit), all new patients with colon cancer (177 and 200 in experimental group and 118 and 100 in control group, respectively) and early breast cancer (444 and 381 in experimental group and 172 and 204 in control group, respectively) were selected. Results In the experimental group, the compliance of medical decisions with CPG was significantly higher in 1999 than in 1996 for colon cancer (73%; 95% CI, 67% to 79% v 56%; 95% CI, 49% to 63%, respectively; P = .003) and similar for the two periods for breast cancer (36%; 95% CI, 31% to 41% v 40%; 95% CI, 35% to 44%, respectively; P = .24). In the control group, compliance was significantly higher in 1999 than in 1996 for colon cancer (67%; 95% CI, 58% to 76% v 38%; 95% CI, 29% to 47%, respectively; P < .001) and identical for the two periods for breast cancer (4%; 95% CI, 1% to 7% v 7%; 95% CI, 3% to 11%, respectively; P = .19). Conclusion The CPG program for cancer management produced persistent changes in medical practice in our cancer network in terms of conformity with CPG.

Breast cancer (BC) is the most common cancer among women and accounts for the highest mortality rates in the developing countries, including Vietnam. D-loop, is a non-coding region in mitochondrialcircular DNA molecules, related to control the replication and transcription of mitochondrial genes. D-loop mutations cause the dysfunction of the respiratory chain, which contributes to the process of BC. SNP rs3937033 (T/C) on D-loop was reported to have the association with BC in Europe America population (OR [95%CI]= 1.98 [1.25–3.12], P=0.036), and Caucasian (OR[95%CI]= 21 [2.15–204.6], P=0.003). In this study, the High Resolution Melting (HRM) method is optimized for genotyping 100/100 cases/controls samples, then to determine the association between the disease and this SNP. TT, TC and CC genotype frequencies in patient group (36 %, 3 % and 61 %) and control group (23 %, 1 % and 76 %) were calculated based on the results of genotyping by optimal HRM method with the annealing temperature is 66 0C. Association analysis result showed that T allele increases the risk of breast cancer patients up to 1.41 times (OR [95% CI] = 1.41 [1.3-1.92], Pallele = 0.03). Therefore, SNP rs3937033 could be a potential biomarker for early BC diagnosis in Vietnamese. However, this research needs to be conducted with a larger sample size to reach the greater confidence.

Background: We aimed to investigate the associations of breast cancer (BC) and cancer-related chemotherapies with cytokine levels, and cognitive function. Methods: We evaluated subjective and objective cognitive function in BC patients before chemotherapy and 3~9 months after the completion of chemotherapy. Healthy volunteers without cancer were also compared as control group. Interleukins (IL) 2, 4, 5, 6, 10, 12p70, 13, 17A, 1β, IFNγ, and TNFα were measured. Associations of cancer status, chemotherapy and cytokine levels with subjective and objective cognitive impairments were analyzed using a regression model, adjusting for covariates, including IQ and psychological distress. Results: After adjustment, poorer performance in semantic verbal fluency was found in the post-chemotherapy subgroup compared to controls (p = 0.011, η2 = 0.070); whereas pre-chemotherapy patients scored higher in subjective cognitive perception. Higher IL-13 was associated with lower semantic verbal fluency in the post-chemotherapy subgroup. Higher IL-10 was associated with better perceived cognitive abilities in the pre-chemotherapy and control groups; while IL-5 and IL-13 were associated with lower perceived cognitive abilities in pre-chemotherapy and control groups. Our findings from mediation analysis further suggest that verbal fluency might be affected by cancer status, although mediated by anxiety. Conclusions: Our findings suggest that verbal fluency might be affected by cancer status, although mediated by anxiety. Different cytokines and their interactions may have different roles of neuroinflammation or neuroprotection that need further research.
