We conducted a prospective study to assess the non-inferiority of adjuvant chemotherapy alone versus adjuvant concurrent chemoradiotherapy (CCRT) as an alternative strategy for patients with early-stage (FIGO 2009 stage IB-IIA) cervical cancer having risk factors after surgery. The condition was assessed in terms of prognosis, adverse effects, and quality of life. This randomized trial involved nine centers across China. Eligible patients were randomized to receive adjuvant chemotherapy or CCRT after surgery. The primary end-point was progression-free survival (PFS). From December 2012 to December 2014, 337 patients were subjected to randomization. Final analysis included 329 patients, including 165 in the adjuvant chemotherapy group and 164 in the adjuvant CCRT group. The median follow-up was 72.1 months. The three-year PFS rates were both 91.9%, and the five-year OS was 90.6% versus 90.0% in adjuvant chemotherapy and CCRT groups, respectively. No significant differences were observed in the PFS or OS between groups. The adjusted HR for PFS was 0.854 (95% confidence interval 0.415-1.757; P = 0.667) favoring adjuvant chemotherapy, excluding the predefined non-inferiority boundary of 1.9. The chemotherapy group showed a tendency toward good quality of life. In comparison with post-operative adjuvant CCRT, adjuvant chemotherapy treatment showed non-inferior efficacy in patients with early-stage cervical cancer having pathological risk factors. Adjuvant chemotherapy alone is a favorable alternative post-operative treatment.

INTRODUCTION: Usage of metformin is associated with improved survival in lung, breast and prostate cancer, and metformin has been shown to inhibit cancer cell growth and proliferation in in vitro studies. Given the lack of clinical data on metformin use in patients with bladder cancer, we aimed to evaluate the role of metformin in their oncological outcomes. METHODS: Medication use data from a prospectively maintained database of 122 patients with non-muscle-invasive bladder cancer treated with intravesical Bacille Calmette-Guerin (BCG), who were recruited under a randomised, double-blinded, controlled clinical trial, was collected and analysed. Kaplan-Meier curves were used to assess overall survival (OS) and disease-specific survival (DSS). RESULTS: At a median follow-up duration of 102 (range 3-357) months, 53 (43.4%) patients experienced disease recurrence and 21 (17.2%) experienced disease progression. There was no significant difference in mortality between patients with and without diabetes mellitus. There was significant difference in OS between patients without diabetes mellitus, patients with diabetes mellitus on metformin and patients with diabetes mellitus but not on metformin (p = 0.033); patients with diabetes mellitus on metformin had the best prognosis. Metformin use was associated with significantly lower DSS (p = 0.042). Other oral hypoglycaemic agents, insulin or statins were not associated with disease recurrence or progression. CONCLUSION Metformin use was associated with improved oncological outcomes in patients with non-muscle-invasive bladder cancer treated with intravesical BCG. Prospective studies with larger patient populations are needed to validate the role of metformin as potential therapy for bladder cancer.

Bladder cancer is one of the common malignant tumors in China, with 75% of bladder cancer being non-muscle invasion with a high recurrence rate after surgery. Intravesical therapy is an useful methods to either directly kill tumor cells by infusing cytotoxic drugs into the bladder or directly or indirectly induce local immune responses of the body through infusing immune agents, such as bacillus calmette guerin, and thus reduce the risk of tumor recurrence and progression. In 2019, the Urological Chinese Oncology Group issued the "Expert consensus on intravesical therapy on non-muscle invasive bladder cancer" . Recently, great progress in the clinical diagnosis and treatment of non-muscle invasive bladder cancer has been achieved domestically and abroad, including the risk assessment of non-muscle invasive bladder cancer, the therapeutic choice of intravesical drugs, the adverse reactions and treatment experience of intravesical therapy, and clinical research on new types of intravesical drugs. This consensus is made according to domestic and overseas evidence-based medicine in combination with current clinical practice and experience of intravesical therapy for non-muscle invasive bladder cancer in China. It is an update of the 2019 expert consensus, with the wish to provide a guidance for domestic clinical standardized intravesical therapy for non-muscle invasive bladder cancer.

The role of carcinoembryonic antigen (CEA) in pancreatic cancer remains poorly understood. Therefore, this study aimed to determine whether CEA is complementary to carbohydrate antigen 19-9 (CA19-9) in prognosis prediction after pancreatic cancer curative resection. We retrospectively reviewed records of 144 stage II curatively resected pancreatic cancer patients with preoperative and postoperative CEA and CA19-9 levels. Patients with normal preoperative CA19-9 were excluded. R0 resection margin, adjuvant treatment, and absence of angiolymphatic invasion were associated with better overall survival. There was no significant difference in median survival according to preoperative CEA levels. However, patients with normal postoperative CA19-9 (59.8 vs.16.2 months, P < 0.001) and CEA (29.4 vs. 9.3 months, P = 0.001) levels had longer overall survival than those with elevated levels. Among 76 patients with high postoperative CA19-9 levels, a better prognosis was observed in those with normal postoperative CEA levels than in those with elevated levels (19.1 vs. 9.3 months, P = 0.004). Postoperative CEA and CA19-9 levels are valuable prognostic markers in resected pancreatic cancer. Normal postoperative CEA levels indicate longer survival, even in patients with elevated postoperative CA19-9.

The objective of this study was to evaluate the risk of recurrence in patients with intermediate-risk non-muscle-invasive bladder cancer (NMIBC) after intravesical instillation with chemotherapeutic agents or Bacillus Calmette-Guerin (BCG) therapy. A cohort of 746 patients with intermediate-risk NMIBC comprised the study group. The primary outcome was time to first recurrence. The recurrence rates of the transurethral resection (TUR) alone, chemotherapy, and BCG groups were determined using Kaplan-Meier analysis. Risk factors for recurrence were identified using Cox regression analysis. In total, 507 patients (68.1%), 78 patients (10.5%), and 160 (21.4%) underwent TUR, TUR+BCG, or TUR+chemotherapy, respectively. After a median follow-up period of 51.7 months (interquartile range=33.1-77.8 months), 286 patients (38.5%) developed tumor recurrence. The 5-yr recurrence rates for the TUR, chemotherapy, and BCG groups were 53.6%+/-2.7%, 30.8%+/-5.7%, and 33.6%+/-4.7%, respectively (P<0.001). Chemotherapy and BCG treatment were found to be predictors of reduced recurrence. Cox-regression analysis showed that TUR+BCG did not differ from TUR+chemotherapy in terms of recurrence risk. Adjuvant intravesical instillation is an effective prophylactic that prevents tumor recurrence in intermediate-risk NMIBC patients following TUR. In addition, both chemotherapeutic agents and BCG demonstrate comparable efficacies for preventing recurrence.

OBJECTIVETo evaluate the efficacy of Chinese medicine (CM) combined adjuvant chemotherapy in postponing relapse and metastasis of radical resected Ib-IIIa stage non-small cell lung cancer (NSCLC) patients, and to explore its effect in improving their quality of life (QOL) and clinical symptoms.

METHODSWe designed a cohort study of 336 radical resected Ib-IIIa NSCLC patients by analyzing disease free survival (DFS) using Log-rank test. They were randomly assigned to the control group (155 cases, treated by adjuvant chemotherapy group) and the test group (181 cases, treated by adjuvant chemotherapy combined CM). By using controlled method, 60 radical resected NSCLC patients undergoing NP/NC program in 2012 (vinorelbine 25 mg/m2, combined with cisplatin 75 mg/m2 on day 1 and day 8/on day 1 or on day 1, 2, and 3; or carboplatin AUC = 5 on day 1) were assigned to the control group (29 cases) and the test group (31 cases). QOL scores (using EORTC QLQ-LC43 questionnaire) and TCM symptoms scores were compared between the two groups before chemotherapy, peri-chemotherapy (one day before the 2nd course of chemotherapy) , and after chemotherapy (20 days after ending the 4th course of chemotherapy).

RESULTS(1) The median DFS was longer in the test group than in the control group, but with no statistical difference between the two groups (42.73 months vs 35.57 months , P = 0.179). In the subgroup analysis, there was statistical difference in IIIa stage DFS. The median IIIa stage DFS of was longer in the test group than in the control group with statistical difference (27.87 months vs 19. 93 months, P = 0.047). (2) In the control study, repeated measured data indicated there was significant difference in physical functions between the two groups (P < 0.05). Total scores for health states decreased more in the test group than in the control group, but with no statistical difference (P > 0.05). Scores for constipation and CM syndrome scores were higher in the test group than in the control group (P < 0.05).

CONCLUSIONSCM had advantages in postponing DFS of radical resected NSCLC patients, especially in IIIa stage. CM could improve their QOL and clinical symptoms during adjuvant chemotherapy.

Bacillus Calmette-Guérin (BCG) is a live vaccine and has the potential to cause local disease and systemic dissemination in immunocompromised hosts, including infants who are infected with human immunodeficiency virus (HIV) through vertical transmission, and patients with primary immunodeficiencies (PID) such as severe combined immunodeficiency (SCID), chronic granulomatous disease (CGD), hyper-IgM syndrome, and defects of the IL12- IFNγ axis (Mendelian susceptibility to mycobacterial diseases, MSMD). Disseminated BCG is extremely difficult to treat. The chance of complete eradication is low unless functional immune response is restored by haematopoietic stem cell transplant. Prolonged use of anti-mycobacterial drugs often causes organ toxicities and drug resistance. Inflammatory complications which develop upon immunoreconstitution post-transplant may necessitate immunosuppressive treatment, which adversely affect immune recovery and increases risks of opportunistic infections. Multiple BCG reactivations can occur in patients with CGD and MSMD, and BCG can remain latent until reactivations take place in adulthood and manifest as disease. It is important for neonatologists, general practitioners, primary care clinicians and nurses working in maternal and child care centres to be aware of BCG-related complications, which may be the first sign of an underlying immunodeficiency. As neonatal BCG is included in standard vaccination schedule in many countries, it is a challenge to identify and avoid administration of BCG to infants who potentially have PIDs. Deferring BCG vaccination is recently advocated to protect highly vulnerable populations, but the appropriate strategy is yet to be determined. Newborn screening for SCID offers a potential to avoid this complication, if an integrated system of screening and vaccination can be organised.

To achieve immune homeostasis in such a harsh environment as the intestinal mucosa, both active and quiescent immunity operate simultaneously. Disruption of gut immune homeostasis leads to the development of intestinal immune diseases such as colitis and food allergies. Among various intestinal innate immune cells, mast cells (MCs) play critical roles in protective immunity against pathogenic microorganisms, especially at mucosal sites. This suggests the potential for a novel MC-targeting type of vaccine adjuvant. Dysregulated activation of MCs also results in inflammatory responses in mucosal compartments. The regulation of this yin and yang function of MCs remains to be elucidated. In this review, we focus on the roles of mucosal MCs in the regulation of intestinal allergic reaction, inflammation and their potential as a new target for the development of mucosal adjuvants.

We evaluated the potential ability of germanium biotite (GB) to stimulate the production of antibodies specific for foot-and-mouth disease virus (FMDV). To this aim, we measured the total FMDV-specific antibody responses and IgM production after vaccination against FMD both experimentally and in the field. GB supplementation with FMDV vaccination stimulated the production of anti-FMDV antibodies, and effectively increased IFN-gamma and TNF-alpha levels. These results suggest that GB may be a novel alternative feed supplement that can serve as a boosting agent and an immunostimulator for increasing the efficacy of FMDV vaccination in pigs.

OBJECTIVETo observe the clinical therapeutic effect of OM-85 BV(OM-85 Broncho-Vaxom) in children with asthma and recurrent respiratory tract infection, and the effect of OM-85 BV on human β-defensins 1 (hBD-1) and immunoglobulin levels.

METHODSSixty-two children with asthma and recurrent respiratory infection treated between 2011 January and December were divided into two groups by the randomized, double blind method: a treatment group and a control group. With inhaling corticosteroids, the treatment group was given OM-85 BV, and the control group was given a placebo. Clinical curative effects and adverse reactions were observed. Serum levels of hBD-1, IgA, IgG, IgM and urea and alanine aminotransferase (ALT) were measured before treatment and 6 months and 12 months after treatment.

RESULTSCompared with the control group and before treatment, the frequency of respiratory tract infection was reduced in the treatment group 6 months and 12 months after treatment (P<0.05), and serum levels of hBD-1, IgA and IgG in the treatment group increased significantly (P<0.05). There was no significant difference in serum levels of urea, ALT and IgM between the control and treatment groups (P>0.05). Mild adverse reactions occurred in 3 cases in the two groups, 2 cases of abdominal pain and 1 cases of constipation.

CONCLUSIONSOM-85 BV can improve serum levels of hBD-1, IgA and IgG, reduce the occurrence of acute respiratory tract infection and cause mild adverse reactions, suggesting its satisfactory therapeutic effect and safety in the treatment of asthma combined with recurrent respiratory tract infection in children.
