Thyroid cancer is one of the most common endocrine malignant tumors, and its molecular pathogenesis is also a process of multiple genes involved in many steps of carcinogenesis. With the development of molecular biology technology, a variety of related gene mutations and epigenetic phenomena have been found in thyroid cancer tissues. It is helpful to understand the latest progress in the research of the gene mutation and epigenetics of thyroid cancer for its early diagnosis, prevention and the development of targeted drugs...

BACKGROUND/AIMS: Lung cancer is one of the leading causes for cancer mortality. The poor therapeutic outcome of non-small cell lung carcinoma (NSCLC) is mainly due to late diagnosis and chemoresistance. In this study, we investigated the role of Musashi1 (MSI1) in NSCLC malignancy and chemoresistance. METHODS: Colony formation, MTT, glucose uptake and lactate production assays were employed to study lung cancer cell malignancy and chemoresistance. RT-PCR and Western blotting were performed to detect mRNA and protein expressions of genes...

Testicular germ cell tumors (TGCTs) are among the most responsive solid cancers to conventional chemotherapy. To elucidate the underlying mechanisms, we developed a mouse TGCT model featuring germ cell-specific Kras activation and Pten inactivation. The resulting mice developed malignant, metastatic TGCTs composed of teratoma and embryonal carcinoma, the latter of which exhibited stem cell characteristics, including expression of the pluripotency factor OCT4. Consistent with epidemiological data linking human testicular cancer risk to in utero exposures, embryonic germ cells were susceptible to malignant transformation, whereas adult germ cells underwent apoptosis in response to the same oncogenic events...

Liver cancer has become the second most deadly malignant disease, with no efficient targeted or immune therapeutic agents available yet. While dissecting the roles of cytoplasmic signaling molecules in hepatocarcinogenesis using an inducible mouse gene targeting system, Mx1-cre, we identified a potent liver tumor-inhibitory effect of synthetic double-stranded RNA (dsRNA), polyinosinic-polycytidylic acid (pIC), an inducer of the Mx1-cre system. Injection of pIC at the pre-cancer stage robustly suppressed liver tumorigenesis either induced by chemical carcinogens or by Pten loss and associated hepatosteatosis...

Rhabdoid tumors (RTs) are aggressive tumors of early childhood characterized by SMARCB1 inactivation. Their poor prognosis highlights an urgent need to develop new therapies. Here, we performed a high-throughput screening of approved drugs and identified broad inhibitors of tyrosine kinase receptors (RTKs), including pazopanib, and the potassium channel inhibitor clofilium tosylate (CfT), as SMARCB1-dependent candidates. Pazopanib targets were identified as PDGFRα/β and FGFR2, which were the most highly expressed RTKs in a set of primary tumors...

<p>Amelanotic melanoma (AM) is one of the great masqueraders in dermatology. It is a very difficult clinical diagnosis to make because these tumors are devoid of pigment and other clues of melanoma. They are commonly misdiagnosed clinically as other benign and malignant conditions. We present a new case of AM in an 84-year-old woman with a history of non-melanoma skin cancer. She had a thin pink plaque that was initially misdiagnosed as a basal cell carcinoma. We also discuss dermoscopy and its valuable role to improve diagnostic accuracy...

Atypical fibroxanthoma (AFX), is a rare type of skin cancer affecting older individuals with sun damaged skin. Since there is limited genomic information about AFX, our study seeks to improve the understanding of AFX through whole-exome and RNA sequencing of 8 matched tumor-normal samples. AFX is a highly mutated malignancy with recurrent mutations in a number of genes, including COL11A1, ERBB4, CSMD3, and FAT1. The majority of mutations identified were UV signature (C>T in dipyrimidines). We observed deletion of chromosomal segments on chr9p and chr13q, including tumor suppressor genes such as KANK1 and CDKN2A, but no gene fusions were found...

Extravascular migratory metastasis (EVMM), also known as pericytic mimicry or angiotropism, is a mechanism of angiocentric tumor spread that has been investigated mainly in cutaneous malignant melanoma where it has been associated with an increased risk of metastasis. In EVMM, the tumor cells spread along the external (ablumenal) aspect of vessels without breaching the endothelium, a process that is therefore distinct from the more widely recognized intraluminal invasion. Although EVMM has also been reported in a limited range of other tumor types, to our knowledge it has not been described in squamous cell carcinoma (SCC)...

Tumor-to-tumor metastasis is a rare phenomenon defined as a to metastasis in a histologically distinct tumor. We report an unusual case of a 51-yr-old woman who presented with a cervical, bleeding lesion diagnosed as a poorly differentiated adenocarcinoma, HPV18+. Imaging studies revealed an unresectable cervical carcinoma with an associated left ovarian multicystic teratoma. A suspicious solid nodule within the teratoma was also reported. Bilateral salpingo-oophorectomy was performed before the cervical tumor was treated...

The distinction between benign and malignant trophoblastic lesions often presents a diagnostic challenge, even in entities with defined morphologic and immunohistochemical criteria. Lesions arising from chorionic-type intermediate trophoblast, namely placental site nodule (PSN) and epithelioid trophoblastic tumor (ETT), can be distinguished by existing criteria. However, a putative intermediate lesion termed "atypical placental site nodule" (APSN) has been described in the literature but is not well-classified...

We report a unique case of a 67-year-old woman with neurofibromatosis type 1, who was also diagnosed with metaplastic spindle cell carcinoma of the left breast. She had many neurofibromatosis lesions on her body, as well as the mass in the left breast. After the breast mass was diagnosed as a malignant mesenchymal tumor by core needle biopsy, the patient underwent left modified radical mastectomy. Subsequently, the pathological analysis of the tumor showed it to be a metaplastic spindle cell carcinoma. The co-occurrence of neurofibromatosis type 1 and breast cancer, in particular metaplastic spindle cell carcinoma, is very rare...

Immune checkpoint inhibitors (ICIs) targeting Cytotoxic T-Lymphocyte-Associated protein 4 (CTLA-4) or Programmed cell Death protein 1 (PD-1) receptors have demonstrated remarkable efficacy in subsets of patients with malignant disease. This emerging treatment modality holds great promise for future cancer treatment and has engaged pharmaceutical research interests in tumour immunology. While ICIs can induce rapid and durable responses in some patients, identifying predictive factors for effective clinical responses has proven challenging...

Fibroids are benign, hormone-dependent tumours of uterine smooth muscle and connective tissue. They are commonly asymptomatic, but can cause symptoms such as heavy menstrual bleeding and pelvic pressure symptoms. Between 20 to 30% of women with heavy menstrual bleeding have fibroids. Fibroids are most prevalent in women aged 30-50 years and there may be a genetic predisposition. They are more common in black women than white women. Other risk factors include obesity and nulliparity. Asymptomatic women should only be referred if their uterus is palpable abdominally, if fibroids distort the uterine cavity or the uterus is larger than 12 cm in length...
