What is the Odds Ratio for Testicular Cancer after Cryptorchidism?

Discussion Cryptorchidism is the failure of one or both testes to descend from the abdomen into the scrotum. Congenital undescended testis (UDT)is common in young infants (1-4% in term infants and 45% in preterm infants) in that the testes will be palpable but remain high, but most testes will descend by 3-6 months and by 9 months of age only 1% remain undescended. The scrotum often appears underdeveloped. Sometimes the testes cannot be identified and is intra-abdominal at birth. Intra-abdominal testes are less likely to migrate to the scrotum and therefore are more likely to remain undescended. Acquired undescended testis is thought to be caused by the spermatic cord not elongating at the same rate as the body (especially the pelvis). A common cause is a fibrous remnant of the processus vaginalis that does not elongate. The scrotum may be normal or underdeveloped. Retractile testes are testis that remain high in the scrotum and/or groin but can be brought down into the scrotum without difficulty. Orchiopexy, where the testes is surgically placed into position within the scrotum, is recommended to be accomplished by around 1 year of age because of the increased risks of cosmetic problems, infertility and testicular malignancy. Cosmetic problems are not uncommon. Boys and men who underwent orchiopexy as infants often will have a smaller testicle or for it to be aligned higher in the scrotum after puberty. Rates of testicular atrophy are about 3-4% and increase to ~14% with ...

Abstract The development of resistance toward current cancer therapy modalities is an ongoing challenge in gynecological cancers, especially ovarian and cervical malignancies that require further investigations in the context of drug- and irradiation-induced resistance. In this regard, curcumin has demonstrated beneficial and highly pleiotropic actions and increased the therapeutic efficiency of radiochemotherapy. The antiproliferative, anti-metastatic, anti-angiogenic, and anti-inflammatory effects of curcumin have been extensively reported in the literature, and it could also act as a chemopreventive agent which...

This study was aimed at investigating the prognostic significance of Baculoviral IAP repeat containing 5 (BIRC5) in lung adenocarcinoma (LAD) lacking EGFR, KRAS, and ALK mutations (triple-negative (TN) adenocarcinomas). Methods: The gene expression profiles were obtained from Gene Expression Omnibus (GEO). The identification of the differentially expressed genes (DEGs) was performed by GeneSpring GX. Gene set enrichment analysis (GSEA) was used to execute gene ontology function and pathway enrichment analysis. The protein interaction network was constructed by Cytoscape. The hub genes were extracted by MCODE and cytoHu...

Conclusion: KIF20A promotes the proliferation and metastasis of bladder cancer cells. Bladder cancer patients with a high KIF20A expression have a worse tumour differentiation and a poor prognosis. KIF20A may become an independent factor that affects the prognosis of bladder cancer patients and a therapeutic target for bladder cancer. PMID: 31093305 [PubMed - in process]

Authors: Mathieu D, Iorio-Morin C Abstract Pineal region tumors represent a heterogeneous group of different histologic entities, for which the management can be a significant challenge, due to their critical location and frequent aggressive behavior. Traditional management includes surgical resection, fractionated radiation therapy, and chemotherapy. Stereotactic radiosurgery (SRS) is being increasingly used in the treatment of these tumors. It is used as primary therapy for pineocytomas and papillary tumors of the pineal region, as an adjuvant radiation boost in combination with radiation or chemotherapy for pine...

Authors: Lunsford LD, Niranjan A, Fallon K, Kim JO Abstract For more than 65 years localization of brain targets suitable for stereotactic radiosurgery has been performed after application of an intracranial guiding device to the cranial vault. After imaging and dose planning the same frame is used to secure the target at the focus of the intersection of the ionizing radiation beams that create the radiobiological effect. Non-invasive immobilization systems first proposed for linear accelerator or proton radiation technologies have now been developed for the Leksell Gamma Knife ICON radiosurgical system. The ICON t...

Authors: Niranjan A, Lunsford LD, Ahluwalia MS Abstract The most common primary cancers that metastasize to the brain are lung cancer, breast cancer, and melanoma. The established management approaches for brain metastasis include stereotactic radiosurgery, fractionated radiation therapy, and surgical resection. In the past the role of medical therapies in brain metastases was limited. In the last decade, our understanding of molecular drivers of brain metastases and CNS penetration of drugs across the blood-brain barrier has improved. The molecular targeted tyrosine kinase inhibitors have shown effectiveness in br...
