We present a case of a purely extracranial, infrasellar craniopharyngioma that initially presented as a mass in nose and nasopharynx. Craniopharyngiomas are usually located within the sella. Purely infrasellar craniopharyngiomas have only rarely been reported in the literature. A 55-year-old man presented with 8-month history of progressive headache and epistaxis. Rhinoscopy revealed polypoidal mass in both the nasal cavities and nasopharynx. Pre-operative biopsy suggested Craniopharyngioma. A battery of tests necessary for the diagnosis of Craniopharyngioma was done which excluded other possibilities. Surgical resection was done and histopathology thereafter was confirmatory of Craniopharyngioma. Adjuvant radiotherapy was given to the patient. The patient is doing well. The Rathke’s pouch arises from the roof of the primitive mouth and grows toward the brain at the fourth week of gestation. Normally, it loses its attachment with the stomadeum completely by the eighth week of gestation. The craniopharyngeal canal (CPC) extends from the floor of the sella to the vomer and may rarely give rise to ectopic craniopharyngiomas. This case shows that such ectopic tumors may arise anywhere along the CPC. We are documenting this case as an atypical rare case of craniopharyngioma probably originating from tooth primordia.  相似文献

Protein degradation by proteasome is essential to the regulation of important cellular functions including cell cycle progression, proliferation, differentiation and apoptosis. Abnormal proteasomal degradation of key regulatory proteins perturbs the normal dynamics of these cellular processes culminating in uncontrolled cell cycle progression and decreased apoptosis leading to the characteristic cancer cell phenotype. Proteasome inhibitors are a novel group of therapeutic agents designed to oppose the increased proteasomal degradation observed in various cancers while restoring key cellular functions such as apoptosis, cell cycle progression, and the inhibition of angiogenesis. Several proteasome inhibitors have been evaluated in pre- and clinical studies for their potential usage in clinical oncology. Bortezomib (Velcade, PS-341) is the first Food and Drug Administration-approved proteasome inhibitor for the treatment of multiple myeloma and mantle cell lymphoma. Bortezomib's ability to preferentially induce toxicity and cell death in tumor cells while rendering healthy cells unaffected makes it a powerful therapeutic agent and has extended its use in other types of malignancies. The ability of bortezomib and other proteasome inhibitors to synergize with conventional therapies in killing tumors in various in vitro and in vivo models makes this class of drugs a powerful tool in overcoming acquired and inherent resistance observed in many cancers. This is achieved through modulation of aberrant cellular survival signal transduction pathways and their downstream anti-apoptotic gene products. This review will discuss the anti-neoplastic effects of various proteasome inhibitors in a variety of cancers with a special emphasis on bortezomib, its mechanism of action and role in cancer therapy. We further discuss the potential use of bortezomib in the treatment of metastatic melanoma.  相似文献

The aims of the UKW2 study were: (1) to further refine treatment for stage I and II favourable histology (FH) patients; (2) to consolidate the UKW1 results for stage III FH patients; (3) to improve the outlook for patients with inoperable primary tumours and those patients with stage IV and unfavourable histology disease. Treatment consisted of primary nephrectomy, wherever possible, followed by chemotherapy and radiotherapy, as dictated by stage and histology. Treatment was refined successfully for stage I and II FH patients. The 4-year event-free survival for these two groups was 94% and 91%, respectively. Stage III FH patients had a 4-year event free survival of 84%. The outlook for patients with clear cell sarcoma of the kidney is as good as for patients with favourable histology, whilst that for patients with anaplastic or rhabdoid variants remains poor. The outlook for the majority of children with Wilms' tumour is now excellent.  相似文献

The microenvironment is increasingly recognized as a crucial aspect of cancer. In contrast and complement to the field''s focus on biochemical factors and extracellular matrix, we characterize a novel aspect of host:tumor interaction – endogenous bioelectric signals among non-excitable somatic cells. Extending prior work focused on the bioelectric state of cancer cells themselves, we show for the first time that the resting potentials of distant cells are critical for oncogene-dependent tumorigenesis. In the Xenopus laevis tadpole model, we used human oncogenes such as mutant KRAS to drive formation of tumor-like structures that exhibited overproliferation, increased nuclear size, hypoxia, acidity, and leukocyte attraction. Remarkably, misexpression of hyperpolarizing ion channels at distant sites within the tadpole significantly reduced the incidence of these tumors. The suppression of tumorigenesis could also be achieved by hyperpolarization using native CLIC1 chloride channels, suggesting a treatment modality not requiring gene therapy. Using a dominant negative approach, we implicate HDAC1 as the mechanism by which resting potential changes affect downstream cell behaviors. Based on published data on the voltage-mediated changes of butyrate flux through the SLC5A8 transporter, we present a model linking resting potentials of host cells to the ability of oncogenes to initiate tumorigenesis. Antibiotic data suggest that the relevant butyrate is generated by a native bacterial species, identifying a novel link between the microbiome and cancer that is mediated by alterations in bioelectric signaling.  相似文献

A case-control study of endogenous hormones and cervical cancer   总被引:2,自引:0,他引:2  
Both parity and oral contraceptive use are associated with elevated circulating levels of sex hormones, at least transiently, and with increased risk of cervical cancer in human papillomavirus (HPV)-infected women. We directly evaluated whether elevations in the physiologic levels of these hormones predispose to the development of cervical neoplasia. We identified 67 premenopausal and 43 postmenopausal women with cervical intraepithelial neoplasia 2, 3, or cervical cancer (>/=CIN2) diagnosed during enrollment of a population-based cohort of 10 077 women. Four controls, two chosen randomly and two chosen from women testing positive for cancer-associated HPV, were matched to each case on menopausal status, age, days since last menses (pre), or years since menopause (post). Sex hormone-binding globulin, oestradiol, oestrone, oestrone-sulphate, dehydroepiandrosterone sulphate, and progesterone were measured in enrollment plasma. There was no consistent association between the sex hormones and risk of >/=CIN2. Excluding cases with invasive disease had a minimal impact on results. Though this case-control study was based on a well-defined population, it was limited by reliance on a single measure of hormone levels taken at the time of diagnosis. Nonetheless, our results do not support the hypothesis that plasma levels of sex hormones have an important bearing on the risk of cervical neoplasia in HPV-infected women.  相似文献

Although the etiology of primary brain tumors is largely unknown, prior studies suggest that DNA repair polymorphisms may influence risk of glioma. Altered DNA repair is also likely to affect the risk of meningioma and acoustic neuroma, but these tumors have not been well studied. We estimated the risk of glioma (n = 362), meningioma (n = 134), and acoustic neuroma (n = 69) in non-Hispanic whites with respect to 36 single nucleotide polymorphisms from 26 genes involved in DNA repair in a hospital-based, case–control study conducted by the National Cancer Institute. We observed significantly increased risk of meningioma with the T variant of GLTSCR1 rs1035938 (ORCT/TT = 3.5; 95% confidence interval: 1.8–6.9; Ptrend .0006), which persisted after controlling for multiple comparisons (P = .019). Significantly increased meningioma risk was also observed for the minor allele variants of ERCC4 rs1800067 (Ptrend .01); MUTYH rs3219466 (Ptrend .02), and PCNA rs25406 (Ptrend .03). The NBN rs1805794 minor allele variant was associated with decreased meningioma risk (Ptrend .006). Risk of acoustic neuroma was increased for the ERCC2 rs1799793 (Ptrend .03) and ERCC5 rs17655 (Ptrend .05) variants and decreased for the PARP1 rs1136410 (Ptrend .03). Decreased glioma risk was observed with the XRCC1 rs1799782 variant (Ptrend .04). Our results suggest that common DNA repair variants may affect the risk of adult brain tumors, especially meningioma.  相似文献
