a malignant peripheral nerve sheath tumor (mpnst) is very rare, representing 3 - 10% of all soft tissue sarcomas. approximately half of all such tumors are diagnosed in patients with neurofibromatosis type 1 (nf1). the extremities are involved most commonly, and the patient’s age is usually 20 - 50 years. herein, we present a case of an mpnst that developed sporadically in an unusual location a...
aim : this study evaluated the results and efficacy of serum ca 19-9 in determining the nature of a pancreatic solid mass in patients referred for investigation of possible malignancy. background : a wide variety of tumor markers have been proposed for pancreatic cancer but currently the only one with any practical usefulness for diagnosis, prognosis, and monitoring of treatment is “ca 19-9 ”. ...
introductio: hematopoietic stem cell transplants (hsct) are considered as treatment options for patients with solid tumors. transplant numbers have changed significantly over the last decade. we have done autologous and allogeneic hsct for treatment of solid tumor patients in our center. methods: in order to show the transplant effect on solid tumor treatment, we collected data from 71 patients...
Background:Chemotherapy-induced neutropenia as a major toxicity of systemic chemotherapy is commonly associated with substantial mortality and morbidity, and thus identifying its determinants is necessary. This study was undertaken to identify main risk factors of severe neutropenia following adjuvant chemotherapy treatment in a community-based population of patients with cancer in Semnan, I...
Various methods for the direct reprogramming of human somatic cells have been developed. However, a therapeutic method to reprogram and eliminate human solid tumor cells has not been developed. Here we show a novel therapeutic method to reprogram and eliminate human solid tumor cells with chemicals. This therapeutic method may be applicable to various human solid tumor cells that express aldo-k...
Recent developments in the kinetics of solid and ascites tumors are discussed in terms of models of tumor growth and treatment with mitotically linked chemotherapeutic agents. Evidence for and the significance of the following phenomena are summarized: feedback control of cell proliferation in solid tumors, nonproliferating tumor cells, the reversion of tumor cells from nonproliferating to prol...
ABSTRACT: Solid tumors of adult kidney are the most malignant tumors of human body After bladder tumors, they are the commonest solid tumors of urinary tract. There is a tendency to study these lesions by modalities other than sonography and for this reason there are some doubts in studying these tumors by sonography. For resolving these doubts , the first step is to reveal the different son...
The stress harbored by the solid phase of tumors is known as solid stress. Solid stress can be either applied externally by the surrounding normal tissue or induced by the tumor itself due to its growth. Fluid pressure is the isotropic stress exerted by the fluid phase. We recently showed that growth-induced solid stress is on the order of 1.3 to 13.0 kPa (10–100 mmHg) – high enough to cause co...

Background: Neuroblastoma is the most common extra cranial malignant solid tumor of childhood. Various molecular and cytogenetic factors have been implicated in the pathogenesis of neuroblastoma, some of which have proven useful in predicting clinical behavior. Over expression of the oncogen N-myc, is an important indicator of prognosis. Materials and Methods: Our study was performed from 20...
