Evaluation of the Therapeutic Effects of Harmine on Anaplastic Thyroid Cancer Cells.

Anaplastic thyroid carcinoma (ATC) is an extremely difficult disease to tackle, with an overall patient survival of only a few months. The currently used therapeutic drugs, such as kinase inhibitors or immune checkpoint inhibitors, can prolong patient survival but fail to eradicate the tumor. In addition, the onset of drug resistance and adverse side-effects over time drastically reduce the chances of treatment.

Mesenteric Cyst with GI Symptoms: A Fluid Approach to Treatment-Case Report and Literature Review.

Mesenteric cysts are defined as a heterogeneous group of intra-abdominal cystic lesions of the mesentery or omentum that may be found in any portion of the gastrointestinal tract from the duodenum to the rectum. The clinical condition is entirely asymptomatic in many patients, particularly with small cysts. The diagnosis is typically incidental and secondary to imaging performed for other purposes.

Papillary Thyroid Cancer Prognosis: An Evolving Field.

Over the last few years, a great advance has been made in the comprehension of the molecular pathogenesis underlying thyroid cancer progression, particularly for the papillary thyroid cancer (PTC), which represents the most common thyroid malignancy. Putative cancer driver mutations have been identified in more than 98% of PTC, and a new PTC classification into molecular subtypes has been proposed in order to resolve clinical uncertainties still present in the clinical management of patients. Additionally, the prognostic stratification systems have been profoundly modified over the last decade, with a view to refine patients' staging and being able to choose a clinical approach tailored on single patient's needs.

Expression and Clinical Utility of Transcription Factors Involved in Epithelial-Mesenchymal Transition during Thyroid Cancer Progression.

The transcription factors involved in epithelial-mesenchymal transition (EMT-TFs) silence the genes expressed in epithelial cells (e.g., E-cadherin) while inducing those typical of mesenchymal cells (e.

Evaluation of Clinicopathological and Molecular Parameters on Disease Recurrence of Papillary Thyroid Cancer Patient: A Retrospective Observational Study.

The American Joint Committee on Cancer has revised the Tumor-Node-Metastasis (TNM) staging system for papillary thyroid cancer (PTC) patients. We examined the impact of this new classification (TNM-8) on patient stratification and estimated the prognostic value of clinicopathological features for the disease-free interval (DFI) in a cohort of 1148 PTC patients. Kaplan-Meier analyses showed that all clinicopathological parameters analyzed, except age and multifocality, were associated significantly with DFI.

Chievitz' juxtaparotid organ, free from cancer.

Introduction: Up to the half of twentieth century, Chievitz organ was considered an embryonal organ, disappearing with growth. But Zenker, in 1953, demonstrated the existence of this organ in adult life, too4.

Review: In this article we review the embryology, the macroscopic and microscopic anatomy, the ultrastructure, the functional significance and the pathology of the Chievitz'Juxtaparotid Organ (CJO).

Perivascular epithelioid cell neoplasm (PEComa) of the uterus: A systematic review.

Background: Perivascular epithelioid cell neoplasm (PEComa) is a rare mesenchymal tumor. Gynecological PEComas account for just over one-fourth of the overall PEComa cases reported in the literature. Surgery is the most recommended primary treatment while adjuvant therapy is generally reserved for high-risk cases.

Bloodless surgery in geriatric surgery.

In bloodless surgery a series of measures has to be implemented to reduce the perioperative need for transfusion of whole blood or its components. Jehovah's Witness are the most representative group of patients opting for bloodless surgery as their faith follows strict believes that prohibits receiving blood. Geriatric patients requiring bloodless surgery are even more delicate and represent a challenge for surgeons.

Association between Pituitary Langerhans Cell Histiocytosis and Papillary Thyroid Carcinoma.

Here we report a case of panhypopituitarism caused by pituitary Langerhans cell hystocitosis (LCH) in a 22-year-old woman affected by papillary thyroid carcinoma (PTC). Although several cases of the coexistence of PTC and LCH within thyroid tissue have been described in relative literature, in this case, the patient presented a unique suprasellar retrochiasmatic histocytosis localization which, to the best of our knowledge, had never been described before in association with PTC. Even if this aspect is not addressed in the present case report, it is worth noting that about 50% of the patients affected either by LCH or PTC are characterized by activating mutations of the proto-oncogene BRAF.

Long-term survival and recurrences after total nerve-sparing surgery for rectal cancer.

Background/aims: In advanced extraperitoneal rectal cancer Japanese surgeons perform the lateral pelvic nodal dissection with only partial pelvic autonomic nerves preservation; instead most Western surgeons prefer the total mesorectal excision (TME) with complete pelvic nerve sparing except for evident neoplastic nervous involvement. Long-term oncological results of the total nerve-sparing TME are reported.

Methodology: From January 1992 to October 1998 71 [corrected] patients with extraperitoneal rectal carcinoma underwent TME with total nerve sparing except in two cases in which only a partial sparing was possible because of macroscopic neoplastic nervous infiltration: 54 anterior resections and 17 abdominoperineal resections were performed.

Laparoscopic retroperitoneal lymphadenectomy for stage I non-seminomatous testicular tumors.

Retroperitoneal lymph node dissection (RPLND) is the most accurate method to evaluate the presence and extent of retroperitoneal nodal metastases in clinical stage I non-seminomatous germ cell testicular carcinoma. In our Department the open "nerve sparing" RPLND is already the standard surgical treatment for these tumors and laparoscopic technique is employed in surgical treatment of digestive diseases as cholelithiasis, hiatal hernias and gastrointestinal tumors; we report our first experience with laparoscopic RPLND in patients with low stage non-seminomatous germ cell testicular tumors (NSGCTT). A laparoscopic modified template RPLND was performed in 5 high-risk patients with non-seminomatous germ cell clinical stage I tumors by a transperitoneal approach.

Stapled hemorrhoidectomy: surgical notes and results.

Recently the surgical treatment of hemorrhoids using a circular stapler device has gained increasing approval. The Longo's procedure reduces the rectal mucosal and hemorrhoid prolapse using a circular stapler to resect transversally a mucosal-submucosal rectal ring in order to restore the correct anatomical relationships of the anal canal structures. The recent availability of a dedicated instrument kit (PPH01 Ethicon Endo-Surgery) allowed an easy diffusion of this technique.

Histopathological features and clinical course of the gastrointestinal stromal tumors.

Background/aims: C-kit expression is a sensitive marker for a specific group of mesenchymal tumors of the gastrointestinal tract, gastrointestinal stromal tumors, the histogenesis and prognosis of which are uncertain.

Methodology: We have investigated the expression of c-kit by immunohistochemical analysis (APAAP method) in 12 out of 13 cases of mesenchymal gastrointestinal neoplasms operated from January 1991 to December 1998, in which the follow-up data were fully available. Furthermore, the c-kit expression was correlated both with the expression of vimentin, CD34 and the mitotic rate, and with the expression of muscle (muscle-specific actin-HHF35 and desmin) or neural (neuron-specific enolase) differentiation markers.
