BACKGROUND Identification of poor prognostic factors in papillary thyroid carcinoma (PTC) patients is important for the patients' care and follow-up. We can sometimes see small tumor clusters without desmoplasia and no evidence of lymphatic emboli around the main tumor mass of PTC. We termed this form of tumor clustering, 'tumor sprouting,' and determined whether these tumors correlate with lym...

 Abstract Liver neoplasm is not an uncommon disease in Asian countries. Liposarcoma is a rare mesenchymal malignant tumor which usually originates in the retroperitoneum and extremities. From 1973 till now about 10 cases of primary liver liposarcoma have been reported. We present the eleventh case in a young adult female with uncommon presentation. She suffered from a huge mass in the right por...

Cluster of differentiation (CD)24 was originally described as a B lymphocyte marker and has recently received considerable attention in cancer research as its overexpression has been observed in several types of carcinoma. The CD24 molecule is a glycosyl-phosphatidylinositol-linked cell surface protein that appears to be associated with aggressive cancers involving invasion and metastasis. Howe...

Background: Meningiomas are common benign tumors of the central nervous system. Patients with meningiomas achieve postoperative optimal functional recovery, but there is a probability of tumor recurrence months or years after surgical resection. This study aims to evaluate the prevalence of recurrent meningioma and the correlation between tumor recurrence and certain factors. Materials and Meth...

Giant cell tumor (GCT) is a primary and benign tumor of bone, albeit locally aggressive in some cases, such as in the epi-metaphyseal region of long bones, predominantly the distal end of femur and proximal end of tibia (1). There are a variety of treatments for a bone affected by GCT, ranging from chemotherapy, radiotherapy, embolization, and cryosurgery, to surgery with the use of chemical or...

This prospective study was designed to assess the prognostic value of tumor-associated antigens, designated 19A211, M344, T138, and T43, with respect to recurrence of primary superficial bladder cancer. Between September 1990 and April 1992, all patients with primary superficial bladder tumors treated by endoscopic resection in 15 participating hospitals were enrolled. Immunostaining for 19A211...

Because of the deficiency lymphatic reflux in tumor, retention tumor interstitial fluid causes aggravation pressure (TIP), which leads to unsatisfactory penetration nanomedicine. It is main inducement recurrence and metastasis. Herein, we design a pyroelectric catalysis-based Nano-lymphatic decrease TIP for enhanced treatments. realizes photothermal therapy decomposition under NIR-II laser irra...

Ovarian cancer (OC) is the most fatal gynecological malignancy, and identifying reliable prognostic indicators can help guide therapeutic treatment. Various tumor marker-guided treatment regimens considerably improve patient prognosis with a better understanding of molecular underpinnings ovarian recurrence metastasis. Fluorine-18-fluorodeoxyglucose Positron emission tomography/computed tomogra...

Inverted papilloma is a common, benign sinonasal tumor with known high rate of recurrence. To prevent recurrences, complete excision inverted essential. In excision, especially, identifying the attachment site and managing meticulously important. this study, we introduce two surgical methods for that can reduce recurrence rate: prelacrimal approach ‘origin cauterization drilling (painting washi...

PURPOSE To inspect the potential diagnostic role of in vivo 1H MRS lipid methylene CH2 to methyl CH3 signal ratio in differentiation of recurrent brain tumor from radiation injury. METHODS Two patients--one with documented recurrence and the other without recurrence--were monitored by means of 1H MRS before and during two years after radiation therapy. The comparative group consisted of 20 pa...
