The mechanisms of IL-17A on promoting tumor metastasis.

In recent decades, extensive studies have indicated that IL-17A plays an important role in tumor progression and metastasis, but the underlying mechanisms are not immediately clear. In this review, we examined the literature from the recent years concerning the study of IL-17A in four kinds of tumor transfer paths, including hematogenous metastasis, lymphatic metastasis, local invasion and transcoelomic metastasis, to summarize the roles and underlying mechanisms of IL-17A on tumor metastasis.

Unusual axillary metastasis of recurrent nasopharyngeal cancer: A case report.

Nasopharyngeal carcinoma (NPC) has a high propensity of metastasis. The most commonly described sites of distant metastasis are the bones, lungs, and liver, whereas axillary metastasis is seldom reported.

Patterns and clinical significance of cervical lymph node metastasis in papillary thyroid cancer patients with Delphian lymph node metastasis.

Although the roles of Delphian lymph node (DLN) metastasis in papillary thyroid cancer (PTC) have been previously reported, there are still limited data on correlations of clinicopathologic factors with DLN metastasis and unique patterns of cervical node subsite metastasis in PTC patients with DLN metastasis. We retrospectively reviewed medical records of 320 patients with a diagnosis of PTC who underwent primary surgery. Clinicopathologic features and DLN metastasis patterns were analyzed for predicting ex...

Reversing the polarization of tumor-associated macrophages inhibits tumor metastasis.

The M2 phenotype is dominant in tumor associated macrophages (TAM), and plays a key role in promoting tumor growth, invasion and metastasis. Converting TAM polarization from M2 to M1 may contribute to eliciting anti-tumor-specific immune responses and inhibiting tumor metastasis. In this study, the effect of reversing the polarization of TAM on tumor metastasis was investigated.

Metastasis of Esophageal Small Cell Carcinoma to the Appendix: A Case Report and Literature Review.

Primary small cell carcinoma (SCC) of the esophagus is characterized by high malignancy with a tendency to metastasize early through lymph and blood circulation. Metastasis of esophageal SCC frequently occurs to distant organs such as liver and lung. However, few cases of appendiceal metastasis have been reported. This paper first presents a pathologically confirmed case with metastasis of esophageal SCC to the appendix. This particular case highlights the importance of pathological diagnosis and provides n...

Metapristone suppresses non-small cell lung cancer proliferation and metastasis via modulating RAS/RAF/MEK/MAPK signaling pathway.

Metastasis is the key phase of cancer progression that characterizes a more advanced stage and a poorer prognosis. The majority of cancer fatalities occur as a consequence of metastasis.

Timeline metastatic progression: in the wake of the « seed and soil » theory.

Little is known about the natural history of cancer and its evolution to metastasis. Paget was the first to postulate the important role played by microenvironment in metastasis progression. Since, the concept of his "seed and soil" theory has been supported and confirmed. Understanding the chronology and natural course that underlie metastasis is mandatory to deepen this concept and to progress in the development of novel therapeutic strategies. A total of 413 patients who underwent treatment for brain met...

MicroRNA-217 suppressed epithelial-to-mesenchymal transition in gastric cancer metastasis through targeting PTPN14.

Gastric cancer (GC) is the third leading cause of cancer-related deaths while the mechanisms underlying its metastasis are not fully understood. In this study, we aimed to explore the relationship between miR-217 and GC metastasis.

Leptomeningeal metastasis of poorly differentiated uterine cervical adenosquamous carcinoma following reirradiation to metastatic vertebrae: A case report.

Leptomeningeal metastasis from cervical adenosquamous carcinoma is extremely rare especially after radiotherapy for vertebral metastasis.

Analysis of gastrointestinal metastasis of primary lung cancer: Clinical characteristics and prognosis.

The prevalence of gastrointestinal metastasis of lung cancer is low. The aim of the present study was to analyze the frequency and clinical characteristics of metastases to the gastrointestinal tract by retrospectively assessing the clinical records of 2,066 patients with lung cancer. A total of 7 patients (0.33%) were diagnosed with gastrointestinal metastasis, including 4 patients with adenocarcinoma, 1 patient with large cell carcinoma and 2 patients with pleomorphic carcinoma. Furthermore, 3 of the pati...

Low incidence of metastasis and recurrence from cutaneous squamous cell carcinoma found in a UK population: Do we need to adjust our thinking on this rare but potentially fatal event?

Cutaneous squamous cell carcinoma (cSCC) is the commonest skin cancer with metastatic potential, however, reported rates of metastasis varies greatly. All cases of primary cSCC on the Isle of Wight between 2005 and 2014 were identified and retrospectively followed for recurrence and/or metastasis. Primary outcome was to identify the rate of metastasis/recurrence from cSCC. Secondary outcomes included associated risk factors for metastasis/recurrence, death from cSCC, and time from diagnosis of primary cSCC ...

Potential clinical value of PET/CT in predicting occult nodal metastasis in T1-T2N0M0 lung cancer patients staged by PET/CT.

We assessed the clinical value of 2-fluoro-2-deoxyglucose (18F-FDG) PET/CT imaging for predicting occult nodal metastasis in non-small cell lung cancer (NSCLC) patients. This retrospective study included 54 patients with T1-2N0M0 NSCLC who had undergone 18F-FDG PET/CT before surgery. Occult nodal metastasis was detected in 25.9% (14/54) of the patients. Immunohistochemical analysis revealed that increased glucose transporter 1 expression was associated with occult nodal metastasis, but hexokinase 2 expressi...

Crosstalk between TEMs and endothelial cells modulates angiogenesis and metastasis via IGF1-IGF1R signalling in epithelial ovarian cancer.

Epithelial ovarian cancer (EOC) is the leading cause of death from gynaecologic malignancies and has a poor prognosis due to metastasis. Drugs targeting the angiogenesis pathway significantly improve patient outcome. However, the key factors linking angiogenesis and metastasis have not been elucidated. In this study, we found Tie2 expressing monocytes (CD14(+)Tie2(+), TEMs) as key contributors to angiogenesis and metastasis of EOC.

Scalp metastasis as an initial presentation of lung adenocarcinoma : A case report and literature review.

Cutaneous metastasis from primary visceral malignancy is a relatively uncommon clinical entity, with a reported incidence of 0.22%-10% among various series. However, the presence of cutaneous metastasis as the first sign of a clinically silent visceral cancer is exceedingly rare.

Differential effects on lung and bone metastasis of breast cancer by Wnt signalling inhibitor DKK1.

Metastatic cancer is a systemic disease, and metastasis determinants might elicit completely different effects in various target organs. Here we show that tumour-secreted DKK1 is a serological marker of breast cancer metastasis organotropism and inhibits lung metastasis. DKK1 suppresses PTGS2-induced macrophage and neutrophil recruitment in lung metastases by antagonizing cancer cell non-canonical WNT/PCP-RAC1-JNK signalling. In the lungs, DKK1 also inhibits WNT/Ca(2+)-CaMKII-NF-κB signalling and suppresse...

Tumour mutation status and sites of metastasis in patients with cutaneous melanoma.

Cutaneous melanoma can metastasise haematogenously and/or lymphogenously to form satellite/in-transit, lymph node or distant metastasis. This study aimed to determine if BRAF and NRAS mutant and wild-type tumours differ in their site of first tumour metastasis and anatomical metastatic pathway.

Ovarian carcinoma presenting as cutaneous nasal metastasis.

Metastatic ovarian cancer uncommonly presents with skin metastasis. When present, skin metastases of ovarian cancer are usually localized in the vicinity of the primary tumor. We report a case of a 58-year-old woman with a rapid growing erythematous, well-defined nodule localized on the left nasal ala. A skin biopsy was performed and histopathological and immunohistochemical findings were compatible with a cutaneous metastasis of adenocarcinoma. A systematic investigation revealed a bilateral ovarian cystad...

Brain Metastasis Of Penile Angiosarcoma.

Angiosarcoma is a rare malignancy originating from vascular endothelial cells. Brain metastasis of aniosarcomas are uncommon up to the literature. Penile angiosarcomas are also seldom among all anjiosarcomas. A case with penile angiosarcoma with confirmed brain metastasis is aimed to be reported and contribute to the literature for similar cases.

Role of secreted protein acidic in hematogenous metastasis of gastric cancer.

To investigate tumor microenvironment of metastasis (TMEM) and the expression of SPARC (secreted protein acidic and rich in cysteine) in gastric cancer, and their relationships with hematogenous metastasis.

Expression of anaesthetic and analgesic drug target genes in excised breast tumour tissue: Association with clinical disease recurrence or metastasis.

Retrospective analyses suggest anaesthetic-analgesics technique during cancer surgery may affect recurrence/metastasis. This could involve direct effects of anaesthetic-analgesic drugs on cancer cells. While μ-opioid receptor over-expression in lung tumours is associated with greater metastasis, other anaesthetic-analgesic receptor targets in cancer recurrence/metastasis remain unexplored. Therefore, we evaluated the association between genetic expression of anaesthetic-analgesic receptor targets and recur...

ABCB5 promotes melanoma metastasis through enhancing NF-κB p65 protein stability.

Melanoma is the most aggressive type of skin cancer. Melanoma has an extremely poor prognosis because of its high potential for vascular invasion, metastasis and recurrence. The mechanism of melanoma metastasis is not well understood. ATP-binding cassette sub-family B member 5 (ABCB5) plays a key role in melanoma growth. However, it is uncertain what function ABCB5 may exert in melanoma metastasis. In this report, we for the first time demonstrate ABCB5 as a crucial factor that promotes melanoma metastasis....

SPOCK1 promotes the invasion and metastasis of gastric cancer through Slug-induced epithelial-mesenchymal transition.

Metastasis is a crucial impediment to the successful treatment for gastric cancer. SPOCK1 has been demonstrated to facilitate cancer metastasis in certain types of cancers; however, the role of SPOCK1 in the invasion and metastasis of gastric cancer remains elusive. SPOCK1 and epithelial-mesenchymal transition (EMT)-related biomarkers were detected by immunohistochemistry and Western blot in gastric cancer specimens. Other methods including stably transfected against SPOCK1 into gastric cancer cells, Wester...

Role of LOXL2 in the epithelial-mesenchymal transition and colorectal cancer metastasis.

Colorectal cancer (CRC) is one of the most dangerous types of malignant tumors, and cancer metastasis is a major factor in the failure of CRC therapy. Recently, LOXL2 (lysyl oxidase-like 2) has been shown to represent a regulator of epithelial-mesenchymal transition (EMT) in different cancer types. However, LOXL2 has not been reported to be involved in CRC metastasis. In this study, we demonstrated that LOXL2 expression is strongly correlated with the rate of CRC metastasis, it participates in the regulatio...

Hepatocellular carcinoma with disseminated skeletal muscle metastasis.

Hepatocellular carcinoma (HCC) is the commonest primary tumor of the liver and carries a poor prognosis when diagnosed late or left untreated. Treatment relies heavily on the stage of the tumor when diagnosed. Extrahepatic metastasis is known to occur; these are mainly reported via autopsy studies or isolated case reports. Knowledge of extrahepatic metastasis is crucial in order to avoid unnecessary surgery. We report a rare case of a patient at our center, diagnosed to have HCC, who underwent treatment suc...

A20 promotes metastasis of aggressive basal-like breast cancers through multi-monoubiquitylation of Snail1.

Although the ubiquitin-editing enzyme A20 is a key player in inflammation and autoimmunity, its role in cancer metastasis remains unknown. Here we show that A20 monoubiquitylates Snail1 at three lysine residues and thereby promotes metastasis of aggressive basal-like breast cancers. A20 is significantly upregulated in human basal-like breast cancers and its expression level is inversely correlated with metastasis-free patient survival. A20 facilitates TGF-β1-induced epithelial-mesenchymal transition (EMT) ...
