The RATIONALE-307 study (ClinicalTrials.gov: NCT03594747) demonstrates prolonged progression-free survival (PFS) with first-line tislelizumab plus chemotherapy versus chemotherapy in advanced lung squamous cell carcinoma (LUSC; N = 360). Here we describe an immune-related gene expression signature (GES), composed of genes involved in both innate and adaptive immunity, that appears to differentiate tislelizumab plus chemotherapy PFS benefit versus chemotherapy. In contrast, a tislelizumab plus chemotherapy PFS benefit is observed regardless of programmed death ligand 1 (PD-L1) expression or tumor mutational burden (TMB)...

Bladder cancer (BC) can be divided into two subgroups depending on invasion of the muscular layer: non-muscle-invasive bladder cancer (NMIBC) and muscle-invasive bladder cancer (MIBC). Its aggressiveness is associated, inter alia, with genetic aberrations like losses of 1p, 6q, 9p, 9q and 13q; gain of 5p; or alterations in the p53 and p16 pathways. Moreover, there are reported metabolic disturbances connected with poor diagnosis-for example, enhanced aerobic glycolysis, gluconeogenesis or haem catabolism.Currently, the primary way of treatment method is transurethral resection of the bladder tumour (TURBT) with adjuvant Bacillus Calmette-Guérin (BCG) therapy for NMIBC or radical cystectomy for MIBC combined with chemotherapy or immunotherapy...

Background A wart is a mucocutaneous illness caused by the growth of HPV-infected skin or mucosal cells. Intralesional immunotherapy makes use of the immune system's ability to identify injected antigens, which might cause a delayed-type hypersensitivity reaction not just to the antigen but also to the wart virus. This, in turn, improves the immune system's ability to identify and eliminate HPV not just at the treated wart but also at distant places, as well as prevent recurrences. Aims and objectives To study the efficacy of the intralesional measles, mumps, and rubella (MMR) vaccine in verruca vulgaris and its side effects...

BACKGROUND: PD-L1 and VISTA are thought to play a role in escape from the immune system, tumor progression, and treatment response in tumoral tissue. The current study aimed to evaluate the effects of radiotherapy (RT) and chemoradiotherapy (CRT) on PD-L1 and VISTA expression in head and neck cancers. METHODS: PD-L1 and VISTA expression were compared between the primary biopsy taken at the time of diagnosis and refractory tissue biopsies of patients who received definitive CRT or recurrent tissue biopsies of patients who had surgery followed by adjuvant RT or CRT...

POEMS syndrome is a rare multisystem paraneoplastic disorder due to an underlying low-level plasma cell dyscrasia. Due to its rarity, there are limited data to guide treatment and there are no consensus guidelines. Therapy choices are dictated by patient characteristics, disease factors and local funding arrangements. The goals of therapy are to eradicate the underlying clone in order to improve quality of life and overall survival. Most evidence has been garnered in the front-line setting. Localised disease responds well to radiotherapy, whilst for those with systemic disease, the best outcomes are demonstrated with induction chemotherapy followed up with high-dose melphalan and stem cell rescue if eligible...

INTRODUCTION: There is a need for a fast, efficient and safe way to induce tolerance in patients with severe allergic rhinitis. Intralymphatic immune therapy has been shown to be effective. METHODS: Patients with severe birch and timothy allergy were randomized and received three doses of 0.1 ml of birch and 5-grass allergen extracts (10,000 SQ units/ml, ALK-Abelló), or birch and placebo or 5-grass and placebo by ultrasound-guided injections into inguinal lymph nodes at monthly intervals...

Cutaneous is an extremely rare metastatic area of bladder urothelial carcinoma. Pure cutaneous metastasis without systemic metastasis is very rare and less than ten cases have been reported in the literature. Our patient had various lymphatic fistulas to her skin due to pelvic lymphadenectomy and radiotherapy in her previous cervical cancer. We believe that the most probable mechanism underlying our patient's cutaneous metastasis is a lymphatic spread via those lymphatic fistulas. Immunotherapy is a very important option for patients who cannot receive cisplatin...

Cancer vaccine is well recognized as a novel but effective way for cancer immunotherapy. Especially, the role of dendritic cells (DCs) in antigen presentation properties is critical for the final performance of cancer vaccine. Herein, a lipid (Li) coated calcium carbonate (CC) vehicle (Li/CC) was employed to load chlorin e6 (Ce6) to serve as a potential in situ vaccine (Li/CC-Ce6) for effective immunotherapy of colorectal cancer. It was suggested that the loaded Ce6 within Li/CCCe6 can be activated under laser irradiation...

The prevalence of allergic diseases is increasing worldwide. It is estimated that more than 30% of the world population is now affected by one or more allergic conditions and a high proportion of this increase is in young people. The diagnosis of allergy is dependent on a history of symptoms on exposure to an allergen together with the detection of allergen-specific IgE. Accurate diagnosis of allergies opens up therapeutic options. Allergen specific immunotherapy is the only successful disease-modifying therapy for IgE-mediated allergic diseases...

INTRODUCTION: Cancer stems from mutations in specific genes that induce uncontrolled cell proliferation. Dendritic cells (DCs) are important immunologic cells and play a crucial role in the induction of an antitumour response. PATIENTS AND METHODS: We examined the immune response mediated by T lymphocytes, helper T cells, cytotoxic T cells, and regulatory T cells, as well as the cytokines [interleukin (IL)-2, IL-12, interferon (IFN)-γ, tumour necrosis factor (TNF)-α and IL-10], produced by these cell populations, in cancer patients (N = 7) undergoing immunotheraphy with autologous DCs...

Allergic diseases represent a complex innate and adoptive immune response to natural environmental allergens with Th2-type T cells and allergen-specific IgE predominance. Allergen-specific immunotherapy is the most effective therapeutic approach for disregulated immune response towards allergens by enhancing immune tolerance mechanisms. The main aim of immunotherapy is the generation of allergen nonresponsive or tolerant T cells in sensitized patients and downregulation of predominant T cell- and IgE-mediated immune responses...

BACKGROUND: Interleukin-8 (IL-8) is a cytokine that plays an important role in tumor progression in a variety of cancer types; however, its regulation is not well understood in oral cancer cells. In the present study, we examined the expression and mechanism of IL-8 in which it is involved by treating immortalized (IHOK) and malignant human oral keratinocytes (HN12) cells with deferoxamine (DFO). METHODS: IL-8 production was measured by an enzyme-linked immunoabsorbent assay and reverse transcriptase-polymerase chain reaction (RT-PCR) analysis...

The morphogenetic events leading to the transendothelial passage of lymphoid and tumoral cells are analyzed in light of a very recent and global theory of intercellular communication designated as the Triune Information Network (TIN). The TIN system is based on the assumption that cell-cell interactions primarily occur through cell surface informations or topobiological procesess, whose mechanisms rely upon expression of adhesion molecules, and are regulated by an array of locally-borne (autocrine/paracrine signals and autonomic inputs) and distantly-borne (endocrine secretions) messages...

BACKGROUND: Ultra-rush induction of immunotherapy with Hymenoptera venom is a reliable and efficacious alternative to the rush induction protocol, though not widely used in European countries yet. Its safety, however, has been intensively discussed over the last few years. The aim of this retrospective case study was to examine the rate of allergic side-effects during our four-hour ultra-rush hymenoptera venom induction regimen. We evaluated risk factors for observed side-effects such as age, gender, severity of previous insect sting reactions according to the H...

In order evaluate the long-term benefit of Specific ImmunoTherapy (SIT), administered either subcutaneously or sublingually, in comparison with drug therapy, in terms of efficacy, tolerability and patients' adherence to the treatment, a three year perspective, observational study was carried out over tree years in a rather large number of allergic subjects. One hundred and ten patients of both sex (50F, 60M; age: 22.4 - 35.5 years) were admitted. Sixty of them were rhinitics, some with concomitant mild intermittent asthma or conjunctivitis; 43 had a persistent asthma, often with concomitant rhinitis...

We compared the adjuvanticity of the synthetic lipopeptide P3CSK4 of bacterial origin and the plant-derived adjuvant saponin using the wheat storage protein gliadin as antigen. Gluten sensitive BALB/c mice were orally immunized with gliadin in a mixture with either lipopeptide or saponin. The gliadin-specific serum IgG response was markedly enhanced by the saponin adjuvant. The lipopeptide adjuvant enhanced the IgG2a response, but reduced IgG1 production. In contrast, the saponin adjuvant enhanced both IgG2a and IgG1, and the sera showed elevated specific IgE concentrations...

The clinical and biological characteristics of neuroectodermal tumours (NETs) are such that their treatment is necessarily multidisciplinary. Surgery is the first therapeutic choice given that it is the only potentially curative treatment for this type of neoplasm. Medical treatment is mainly indicated in the treatment of metastatic disease and must be separated into three basic options: chemotherapy, immunotheraphy and hormone treatment. Owing to the low proliferative index generally found in NETs, chemotherapy is not very effective as a means of controlling tumour growth...

BACKGROUND: dermatophagoides pteronyssinus (Der PI) is the major allergen which causes allergic asthma and perennial rhinitis. The extracts of Der PI may be used in treatment of patients who are unresponsive to pharmacological treatment and avoidance of allergens. The success of immunotherapy (IT) depends on the selection of appropriate patients and allergens as well as a regular follow up. OBJECTIVE: three different groups of IT materials and a placebo were tested on 34 patients with Der PI sensitive asthma...

The inflammatory bowel diseases frequently require surgery because of intestinal complications. Animal models of inflammatory bowel disease, in particular those that histopathologically resemble Crohn's disease, are characterized by increased mucosal TNF production, and anti-TNF antibodies have shown efficacy in decreasing disease activity. These data have provided a rationale for immunotheraphy of Crohn's disease. Administration of anti-TNF antibodies to patients with Crohn's disease not responding to standard immunosuppressive treatment rapidly induced complete remissions, and healing of intestinal ulceration...
