The Hedgehog (Hh) signalling pathway is involved in cell differentiation, growth and tissue polarity. This pathway is also involved in the progression and invasion of various human cancers. Osteosarcoma, a subtype of bone cancer, is commonly seen in children and adolescents. Typically, pulmonary osteosarcoma metastases are especially difficult to control. In the present paper, we summarise recent studies on the regulation of osteosarcoma progression and metastasis by downregulating Hh signalling. We also summarise the crosstalk between the Hh pathway and other cancer-related pathways in the tumourigenesis of various cancers...

Colorectal cancer (CRC) is a frequently occurring disease, yet diagnosed at a local stage in only 40% of cases. Lung metastases (LM) appear in 5-15% of patients and, left untreated, carry a very poor prognosis. Some CRC patients may benefit from a potentially curative LM resection, but success and benefit are difficult to predict. We discuss prognostic factors of survival after lung metastasectomy in CRC patients under several scenarios (with/ without prior liver metastases; repetitive pulmonary resections)...

PURPOSE: The molecular underpinnings that may prognosticate survival and increase our understanding of tumor development and progression are still poorly understood. This study aimed to define the molecular signatures for malignancy in small cell lung carcinoma (SCLC), which is known for its highly aggressive clinical features and poor prognosis. EXPERIMENTAL DESIGN: Using clinical specimens, we performed a comparative proteomic analysis of high-grade SCLCs and low-grade pulmonary carcinoid tumors (PCTs), both of which are types of neuroendocrine tumors...

Malignant melanoma has shown increased incidence and high mortality rate in the last three decades. In this study, we investigated whether combination therapy with ch282-5 (a novel BH3 mimetic) and microwave hyperthermia could display synergistic antitumor effects against melanoma. Our results indicated that combination therapy reduced the viability and proliferation of melanoma cells. Through inhibiting the expression of anti-apoptotic proteins of Bcl-2 and IAP family and activating MAPK proteins, combined hyperthermia enhanced ch282-5-induced apoptosis...

BACKGROUND: Increasing evidence indicates that microRNA dysfunction is involved in the pathogenesis and progression of cancer. MicroRNA-222 (miR-222) is upregulated in papillary thyroid carcinoma (PTC); however, the role of miR-222 in invasion and metastasis of PTC remains unknown. In this study, we investigated the function of miR-222 and its underlying mechanism in the progression of PTC. METHODS: The expression of miR-222 was detected by qRT-PCR and its correlation with various clinical characteristics was analyzed...

BACKGROUND: In human pulmonary malignancies, the SRY-box containing gene 30 (SOX30) is a known cancer-suppressing gene. Nevertheless, its molecular role and clinical effects remains unknown in bladder cancer. METHODS: SOX30 mRNA expression was quantified in bladder cancer tissue, paired adjacent normal tissue, and cell lines with qRT-PCR. SOX30 protein expression in BC tissue and cell lines was evaluated via western blotting and immunohistochemistry. In addition, the clinical and prognostic significance of SOX30 in BC were assessed using Kaplan-Meier analysis...

BACKGROUND: Advances in epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI) treatment led to research on the mechanism of the resistance have revealed that an occurrence of T790M gene mutation generated in exon 20 of the EGFR gene is associated with approximately 50% to 60% of observed resistance. Osimertinib, a 3rd-generation EGFR-TKI, has been shown to be effective against both EGFR tyrosine kinase inhibitor-sensitizing and T790M resistance mutations. In this study, we prospectively investigate the efficacy and safety of osimertinib in elderly patients aged ≥75 years, with ineffective prior EGFR-TKI treatment or with recurrence of EGFR-TKI mutation-positive or T790M mutation-positive nonsmall-cell lung cancer...

RATIONALE: Pleomorphic adenoma, the most common tumor of the salivary glands, is usually benign. It is well known, however, that pleomorphic adenomas occasionally undergo malignant transformation to carcinoma ex pleomorphic adenoma and can metastasize. More rarely pleomorphic adenomas can metastasize without histological malignant transformation. We herein report an unusual case of pleomorphic adenoma with multiple metastases comprehensively demonstrated on F-18 fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT)...

We present a case of 55-year-old man who complained of dyspnea and sputum for a month. He was an ex-smoker having a history of prostate cancer and pulmonary tuberculosis. Chest radiographs revealed small to moderate amount of bilateral pleural effusions. Pigtail catheters were inserted and drainage was performed. The pleural fluid contained malignant cells, arranged in large clusters and tightly cohesive groups. These cytologic findings could not with certainty be ascribed to prostate cancer. We performed immunocytochemical (ICH) panel studies to determine the origin of cancer metastasis...

PURPOSE: Curcumin is expected to have beneficial effects including an anti-cancer effect. However, its lower bioavailability is a critical concern and limits the utility of curcumin in clinical practice. In this study, we investigated whether transpulmonary delivery of curcumin is pharmacologically effective along with improving its bioavailability in mice with lung metastasis. METHODS: C57BL/6J mice were injected with B16F10 melanoma cells via their tail vein and given curcumin by pulmonary administration every other day...

Ameloblastic carcinoma (AC) is a very rare odontogenic malignancy. Primary AC is more common in maxilla, while secondary AC is more common in mandible. Histologically, it is an ameloblastoma with features of cancer. Presence of metastasis is not necessary to establish the diagnosis. This tumor usually metastasises in bone or lungs. We report a case of aggressive secondary AC of mandible with lung metastasis. There are few cases in medical literature discussing management of AC with lung metastasis. In this case, a 42-year woman, who was diagnosed with ameloblastoma of right mandible, was treated with right hemi-mandibulectomy...

The over-expression of aminopeptidase N on diverse malignant cells is associated with the tumor angiogenesis and metastasis. In this report, one new series of leucine ureido derivatives containing the triazole moiety was designed, synthesized and evaluated as APN inhibitors. Among them, compound 13v showed the best APN inhibition with an IC50 value of 0.089 ± 0.007 μM, which was two orders of magnitude lower than that of bestatin (IC50  = 9.4 ± 0.5 μM). Compound 13v also showed dose-dependent anti-angiogenesis activities...
