  • Many cancers arise from sites of chronic inflammation, which creates an inflammatory microenvironment surrounding the tumor. Inflammatory substances secreted by cells in the inflammatory environment can induce the proliferation and survival of cancer cells, thereby promoting cancer metastasis and angiogenesis. Therefore, it is important to identify the role of inflammatory factors in cancer progression. This review summarizes the signaling pathways and roles of C-reactive protein (CRP) in various cancer types, including breast, liver, renal, and pancreatic cancer, and the tumor microenvironment. Mounting evidence suggests the role of CRP in breast cancer, particularly in triple-negative breast cancer (TNBC), which is typically associated with a worse prognosis. Increased CRP in the inflammatory environment contributes to enhanced invasiveness and tumor formation in TNBC cells. CRP promotes endothelial cell formation and angiogenesis and contributes to the initiation and progression of atherosclerosis. In pancreatic and kidney cancers, CRP contributes to tumor progression. In liver cancer, CRP regulates inflammatory responses and lipid metabolism. CRP modulates the activity of various signaling molecules in macrophages and monocytes present in the tumor microenvironment, contributing to tumor development, the immune response, and inflammation. In the present review, we overviewed the role of CRP signaling pathways and the association between inflammation and cancer in various types of cancer. Identifying the interactions between CRP signaling pathways and other inflammatory mediators in cancer progression is crucial for understanding the complex relationship between inflammation and cancer.

  • Inflammatory myofibroblastic tumor, histologically characterized by the presence of bland-locking spindle cells and infiltration of chronic inflammatory cells, is extremely rare in the gastric wall. We report a case of gastric inflammatory myofibroblastic tumor In a 27-month-old boy. The fine needle aspiration biopsy from the mass showed loose clusters or scattered spindle cells and inflammatory cells, predominantly of lymphocytes and plasma cells. The spindle cells resembled fibroblasts or myofibroblasts. Differential diagnosis from benign and malignant diseases involving abdominal cavity was discussed.

  • The Inflammatory myofibroblastic tumor (inflammatory pseudotumor) is a rarely occurring soft tissue lesion of unknown etiology. It can be of any location, but commonly it is found in lungs. It has been considered as a nonneoplastic reactive inflammatory lesion, but nowadays, confusion and dispute about its character is increasing due to its high recurrence rate and metastasis. We present a patient who had been diagnosed with an inflammatory pseudotumor in the right maxilla area, 1 year before visiting our hospital. After that, her pain and swelling did not resolved and she visit our hospital. On radiographic examination, aggressively infiltrative growth of the lesion with destruction of adjacent bony structure was noted. We found unusual aggressiveness of the inflammatory myofibroblastic tumor of the head and neck region. Because the typical behavior of the inflammatory myofibroblastic tumor is not defined yet, we recommend the surgical excision of the lesion and close follow-up.

  • Inflammatory myofibrolastic tumor (IMT) is a rare borderline neoplasm. It frequently occurs in the lung but occasionally occurs in extrapulmonary sites such as the genitourinary tract, gastrointestinal tract, breast, salivary glands, sinonasal tract, orbit, and the central nervous system. Laryngeal involvement of IMT is very rare. A 61-year-old woman who complained of hoarseness persisting for 3 months visited our hospital. Laryngoscopy showed an elevated lesion in the right true vocal cord. Incisional biopsy was confirmed as larygeal inflammatory myofibrolastic tumor. We performed a transoral excision with CO2 LASER under suspension examination. Regional recurrence or distant metastasis was not observed after 9 months of follow-up. Herein we report a case of larygeal inflammatory myofibrolastic tumor that was treated with surgery alone, with a literature review.

  • Diversity and flexibility are two typical hallmarks of macrophages. Two types of macrophages, M1(classically activated macrophages) and M2(alternatively activated macrophages) exist at both ends of the commonly known macrophage polarization. M1 macrophages have inflammatory properties and are primarily responsible for defending against invading bacteria in our body. On the other hand, M2 macrophages are involved in anti-inflammatory responses and tissue remodeling. Polarized migration of macrophages is of increasing interest in regulating the initiation, generation, and resting phases of inflammatory diseases. In this review, it intend to discuss the properties and functions of tumor-associated macrophages based on polarized macrophages that affect inflammatory diseases. In addition, the purpose of this study is to investigate a molecular imaging approach that targets macrophages that affect tumor growth by controlling the polarization of macrophages that affect tumor diagnosis and treatment.

  • Aim: Pendulous monkshood root is traditionally used for the treatment of several inflammatory pathologies such as rheumatisms, wounds, pain and tumors in China. In this study, the anti-inflammatory and anticancer activities and the mechanism of crude ethanol extract of pendulous monkshood root (EPMR) were evaluated and investigated in vitro. Materials and Methods: The cytotoxic effects of EPMR on different tumor cell lines were determined by the MTT method. Cell apoptosis and cell nucleus morphology were assessed by Hoechst 33258 staining. Moreover, nitric oxide (NO) levels and intracellular oxidative stress in peritoneal macrophages were determined to further elucidate mechanisms of action. Results: The data showed that EPMR could produce significant dose-dependent toxicity on three kinds of tumor cells. Furthermore, EPMR displayed obvious anti-inflammatory effects on LPS-induced mouse peritoneal macrophages at the dosage of 4 - 200 ${\mu}g/mL$. The results demonstrated the therapeutic potential of Pendulous Monkshood Root on cancer and inflammatory diseases. Conclusion: Our results indicate that EPMR has anti-inflammatory and anticancer properties, suggesting that pendulous monkshood root may be a useful anti-tumor and anti-inflammatory reagent in the clinic.

  • Donggwaja (Benincasae Semen), the seed of Benincasa hispida (Thunb.) Cogn., has been used in Korean traditional medicine to control the body heat and water retention caused by various diseases. Both the symptoms targeted by the herbal medicine in clinic and studies with disease mouse models support the potential anti-inflammatory effect of Donggwaja. However, it is less understood how Donggwaja exerts its possible anti-inflammatory effect. Here, we present evidence that Donggwaja suppresses macrophage inflammatory reactions via expressing tumor necrosis factor a-induced protein 3 (TNFAIP3 or A20) and suppressing NF-kB activity. The ethanol extract of Donggwaja (EED) showed no toxicity when added to RAW 264.7 cells less than 100mg/ml. When treating the cells for 16 h, EED significantly suppressed the nuclear localization of NF-kB, suggesting that EED suppresses NF-kB activity. Concordantly, a semi-quantitative RT-PCR analysis showed that EED decreased the expression of prototypic pro-inflammatory cytokines, such as tumor necrosis factor (TNF)-a, IL(interleukin)-6, and IL-1b. EED induced in RAW 264.7 cells the expression of A20, a ubiquitin modulator that suppresses inflammatory signaling cascades initiated from TLR4 and TNF and IL-1 receptors, while not affecting the induction of Nrf2, an anti-inflammatory factor that could suppress the effect of NF-kB. These results suggest that EED exerts its suppressive effect on inflammation, at least in part, by expressing anti-inflammatory factor A20 and suppressing pro-inflammatory factor NF-kB activity.

  • Inflammatory myofibroblastic tumor was widely known as inflammatory pseudotumor, commonly developed as a solid mass in lung. The endobronchial inflammatory myofibroblastic tumor is a very rare case where only a few cases have been reported. We report a 13-year-old girl who had coughing for 5 months. The simple chest X-ray and computued tomography of the chest revealed a mass which obstructed the right lower lobe bronchus and pneumonic consolidation. The fiberoptic bronchoscopic finding was mostly gelatinous, gray-yellowish mass that obstructed the airway of right lower lobe bronchus nearly, and was considered as a chondroid hamartoma pathologically. Right lower lobectomy of lung was performed. The mass was confirmed as a endobronchial inflammatory myofibroblastic tumor The patient was discharged without complication and with outpatient followup.

  • Inflammatory myofibroblastic tumor (IMT), normally referred to as inflammatory pseudotumor, is a fairly rare condition. Fine needle aspiration cytology (FNAC) of IMT has only rarely been reported. Here, we describe one such case of pulmonary inflammatory myofibroblastic tumor. A 30-year-old man presented with a 2.8cm-sized mass in his lung. Chest CT revealed a well defined, poorly enhancing mass. FNAC showed some fascicular or swirled clusters of spindle cells, admixed with occasional inflammatory cells and foamy histiocytes. The majority of the tumor cells evidenced bland, elongated nuclei, but infrequent pleomorphic nuclei. Some of the tumor cells evidenced nuclear grooves and intranuclear inclusions. Although the cytological differentiation of IMT from malignant lesions is not immensely problematic, due to the general paucity of cytological and nuclear atypia, a definite cytological diagnosis of IMT cannot be rendered simply by FNAC. Therefore, a diagnosis of IMT may be suggested via exclusive diagnosis.
