A novel therapeutic strategy for non-muscle invasive bladder cancer: OncoTherad® immunotherapy associated with platelet-rich plasma. Int Immunopharmacol 2023; 123:110723. [PMID: 37531827 DOI: 10.1016/j.intimp.2023.110723] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/28/2023] [Revised: 07/25/2023] [Accepted: 07/26/2023] [Indexed: 08/04/2023]
Abstract
Patients with non-muscle invasive bladder cancer (NMIBC) that are unresponsive to Bacillus Calmette-Guérin (BCG) have historically had limited treatment options. A new perspective is represented by OncoTherad® (MRB-CFI-1) immunotherapy, a nanostructured inorganic phosphate complex associated with glycosidic protein, developed by the University of Campinas in Brazil. Previous studies have shown that Platelet-Rich Plasma (PRP) also acts on immune activation and exerts antitumor effects. This study characterized the effects of the OncoTherad® associated with PRP in the treatment of NMIBC chemically induced in mice. When treated intravesically with PRP only, mice showed 28.6% of tumor progression inhibition rate; with OncoTherad® 85.7%; and with OncoTherad®+PRP 71.4%. Intravesical treatments led to distinct activation of Toll-like Receptors (TLRs) 2 and 4-mediated innate immune system in the interleukins (canonical) and interferons (non-canonical) signaling pathways. OncoTherad® isolated or associated with PRP upregulated TLR4 and its downstream cascade mediators as well as increased interleukins 6 (IL-6) and 1β (IL-1β), and interferon-γ (IFN-γ). In this way, the NMIBC microenvironment was modulated to a cytotoxic profile correlated with the IL-1β increase by stimulating immune pathways for IFN-γ production and consequent cytotoxic T lymphocytes (as CD8+ T-cells) activation and regulatory T-cells (Tregs) reduction. In addition, PRP did not trigger carcinogenic effects through the biomarkers evaluated. Considering the possibility of personalizing the treatment with the PRP use as well as the antitumor properties of OncoTherad®, we highlight this association as a potential new therapeutic strategy for NMIBC, mainly in cases of relapse and/or resistance to BCG.

Abstract
RATIONALE Rectum ulcer is a disease of the digestive system, the main symptoms of which includes bloody diarrhea, abdominal pain, hematochezia, etc. At present, drug therapy and surgery are the most common treatments. Platelet-rich plasma (PRP) contains high concentrations of platelets and has been used to promote wound healing. However, the utilization of PRP in rectal ulcers has rarely been reported. PATIENT CONCERNS The patient had reported a complaint of blood dripping from the stool for more than 4 months. She had a history of surgery for rectal cancer with postoperative chemotherapy and radiotherapy 19 years prior. Mesalazine suppository was given to her for about 4 months, and glutamine capsules for 2 months, but the rectal ulcer remained unhealed. DIAGNOSIS A rectal ulcer was observed on colonoscopy, and the biopsy result was tubular adenoma. INTERVENTIONS Autologous PRP treatment was performed for the patient under an anorectal scope together with basic supportive care. OUTCOMES The ulcer nearly healed within 9 days after twice PRP treatments. LESSONS PRP treatment may bring about novel treatment options for rectal ulcers.

Poly (L-Lactic Acid) Cell-Laden Scaffolds Applied on Swine Model of Tracheal Fistula. J Surg Res 2022; 277:319-334. [PMID: 35552075 DOI: 10.1016/j.jss.2022.03.024] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/24/2021] [Revised: 02/20/2022] [Accepted: 03/21/2022] [Indexed: 11/22/2022]
Abstract
INTRODUCTION Tracheal fistula (TF) treatments may involve temporary orthosis and further ablative procedures, which can lead to infection. Thus, TF requires other therapy alternatives development. The hypothesis of this work was to demonstrate the feasibility of a tissue-engineered alternative for small TF in a preclinical model. Also, its association with suture filaments enriched with adipose tissue-derived mesenchymal stromal stem cells (AT-MSCs) was assessed to determine whether it could optimize the regenerative process. METHODS Poly (L-Lactic acid) (PLLA) membranes were manufactured by electrospinning and had morphology analyzed by scanning electron microscopy. AT-MSCs were cultured in these scaffolds and in vitro assays were performed (cytotoxicity, cellular adhesion, and viability). Subsequently, these cellular constructs were implanted in an animal small TF model. The association with suture filaments containing attached AT-MSCs was present in one animal group. After 30 d, animals were sacrificed and regenerative potential was evaluated, mainly related to the extracellular matrix remodeling, by performing histopathological (Hematoxylin-Eosin and trichrome Masson) and immunohistochemistry (Collagen I/II/III, matrix metalloproteinases-2, matrix metalloproteinases-9, vascular endothelial growth factor, and interleukin-10) analyses. RESULTS PLLA membranes presented porous fibers, randomly oriented. In vitro assays results showed that AT-MSCs attached were viable and maintained an active metabolism. Swine implanted with AT-MSCs attached to membranes and suture filaments showed aligned collagen fibers and a better regenerative progress in 30 d. CONCLUSIONS PLLA membranes with AT-MSCs attached were useful to the extracellular matrix restoration and have a high potential for small TF treatment. Also, their association with suture filaments enriched with AT-MSCs was advantageous.

Abstract
Purpose: To evaluate whether using platelet-rich plasma (PRP) in the graft recipient
bed after the resection of a neoplasia can influence its recurrence because
this product stimulates angiogenesis, mitogenesis and chemotaxis. Methods: A study with 30 rats Wistar (Rattus norvegicus albinus),
which were separated into group A (induction of carcinogenesis, PRP in the
postoperative period) and group B (induction of carcinogenesis, absence of
PRP in the postoperative period), with 15 animals in each. Carcinogenesis
was induced on the skin of the animals’ chest by the topical application of
0.5% dimethylbenzantracene (DMBA) diluted in acetone. After surgical
resection of the induced neoplasia, PRP was used to stimulate angiogenesis
before surgical wound synthesis. Data on the control and experimental groups
and macroscopic and microscopic variables were evaluated using analysis of
variance and the Tukey’s test (5%). Results: It was possible to determine that the use of PRP is good in reconstructive
surgeries, but it is contraindicated in patients during tumor resection, as
it can cause changes in the surgical bed, in addition to stimulating
recurrences and metastases. Conclusions: PRP may interact with tumour cells that were in the recipient site of the
surgical wound during the resection of a neoplasia, and a local recurrence
process can be triggered by applying this product.

Abstract
Non-muscular invasive bladder cancer (NMIBC) is one of the most common cancer and major cause of economical and health burden in developed countries. Progression of NMIBC has been characterized as low-grade (Ta) and high grade (carcinoma in situ and T1). The current surgical intervention for NMIBC includes transurethral resection of bladder tumor; however, its recurrence still remains a challenge. The BCG-based immunotherapy is much effective against low-grade NMIBC. BCG increases the influx of T cells at bladder cancer site and inhibits proliferation of bladder cancer cells. The chemotherapy is another traditional approach to address NMIBC by supplementing BCG. Notwithstanding, these current therapeutic measures possess limited efficacy in controlling NMIBC, and do not provide comprehensive long-term relief. Hence, biomaterials and scaffolds seem an effective medium to deliver therapeutic agents for restructuring bladder post-treatment. The regenerative therapies such as stem cells and PRP have also been explored for possible solution to NMIBC. Based on above-mentioned approaches, we have comprehensively analyzed therapeutic journey from traditional to regenerative interventions for the treatment of NMIBC.

Abstract
The theory of cancer stem cells (CSCs) proposes that the different cells within a tumor, as well as metastasis deriving from it, are originated from a single subpopulation of cells with self-renewal and differentiation capacities. These cancer stem cells are supposed to be critical for tumor expansion and metastasis, tumor relapse and resistance to conventional therapies, such as chemo- and radiotherapy. The acquisition of these abilities has been attributed to the activation of alternative pathways, for instance, WNT, NOTCH, SHH, PI3K, Hippo, or NF-κB pathways, that regulate detoxification mechanisms; increase the metabolic rate; induce resistance to apoptotic, autophagic, and senescence pathways; promote the overexpression of drug transporter proteins; and activate specific stem cell transcription factors. The elimination of CSCs is an important goal in cancer therapeutic approaches because it could decrease relapses and metastatic dissemination, which are main causes of mortality in oncology patients. In this work, we discuss the role of these signaling pathways in CSCs along with their therapeutic potential.

Abstract
Bladder cancer is the fifth most common disease in the United States, and the treatment and alternatives for patients have not changed in the last decades. Silver nanoparticles (AgNP) have been used in the treatment of various cancer, mainly because of the antineoplastic activity; however, their use and the molecular mechanisms towards bladder cancer still unexplored. Therefore, this work aims to evaluate the in vitro and in vivo antitumoral mechanisms of biogenic silver nanoparticles synthesized from Fusarium sp. First, AgNP showed cytotoxicity in a dose- and time-response relationship and detailed analysis demonstrated the induction of cell death via apoptosis, also inhibiting cell migration and proliferation in bladder carcinoma cell line 5637. Next, it was evaluated the antitumoral activity of AgNP against non-muscle invasive bladder cancer (NMIBC). Bladder cancer was chemically induced with N-methyl-N-nitrosourea (MNU) on C57BL/6JUnib female mice and treated by intravesical route with AgNP concentrations of 0.5, 0.2, and 0.05 mg/mL. Finally, treatment with AgNP (0.05 mg/mL) led to 57.13% of tumor regression, with 14.28% of the animals showing normal urothelium, and 42.85% showing flat hyperplasia, considered to be a benign lesion. Overall, these findings demonstrated that AgNP might be a cost-effective alternative and promising candidate for the treatment of bladder cancer.

Abstract
Platelet-rich-plasma (PRP) is an autologous human platelet concentrate extracted from plasma. PRP has been investigated in order to be used in many fields, with emphasis on the musculoskeletal field applied to sports injuries, as well as on other medical fields such as cardiac surgery, gynecology, pediatric surgery, urology, ophthalmology and plastic surgery. Cancer treatment is another important field where PRP should be investigated; thus, it is important validating PRP preparation protocols to be used in clinical research. Many protocols should be revised since, overall, most studies do not provide necessary information to allow them to be multiplied or replicated. The current review focuses on several topics about cancer, mainly on innovative studies about PRP use as a feasible therapeutic alternative to treat bladder cancer - a field where it could play a key role. Relevant aspects such as platelets' contribution to immune regulation and the supportive role they play in innate and adaptive immune functions are also addressed. Another important topic reviewed in the current study refers to inflammatory process regulation associated with cancer and thrombosis sites, which indicated that tumor-induced platelet activation could be used as an important therapeutic target in the future. New aspects concerning nitric oxide's ability to restrain platelet adhesion and aggregation in order to slow metastasis progress in cancer patients provide an important advantage in cancer treatment. Finally, the current review has pointed out perspectives and the main concerns about, and possibilities of, PRP use in cancer treatment.

Abstract
Bladder cancer is one of the most common urogenital tumors. Its prevalence is increasing worldwide, especially men. The cyclooxygenase-2 (COX-2) enzyme has been shown to increase in bladder cancer and has a direct relationship with tumor progression. Non-steroidal anti-inflammatory drugs (NSAIDs) reduce the growth of the tumor by inhibiting the COX-2 enzyme. NSAIDs have other effects unrelated to COX that provide anticancer properties. Also, similar to NSAIDs, anticancer effects of paracetamol have been shown in many studies. Therefore we hypothesize intravesical paracetamol application will have beneficial effects in the treatment of non-muscle invasive bladder cancer (NMBIC).

Abstract
BACKGROUND Cisplatin (Cis), is a potent chemotherapeutic drug. However, Cis nephrotoxicity is high, thus limiting its use. Platelet-rich plasma (PRP) is an autologous product, easy to get from blood centrifugation. The aim of this study is to investigate the effects of PRP in reversing Cis-induced nephrotoxicity. MATERIALS AND METHODS Thirty-two adult albino rats were distributed into Group I, the control group; Group II, in which the rats received Cis (5 mg·kg-1 ·day -1 , intraperitoneal); Group III and Group IV, in which the rats received Cis, followed by normal saline and PRP distribution, respectively (1 ml) over the renal surface 24 hr later. All rats were killed on the eighth day of the experiment. Histopathological changes were examined. RESULTS Glomerular atrophy, tubular degeneration, interrupted PAS reaction, highly expressed caspase-3, and ultra-structural changes were observed after Cis injection, which improved with PRP administration. CONCLUSION PRP reduced acute kidney injury through the epithelial GFs.
