Introduction: 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 uptil now about 10 cases of primary liver liposarcoma have been reported.In this article we present the eleventh case in a young adult female. Case report: The patient was a 21 year old fem...
The efficacy of neoadjuvant chemotherapy (NAC) is controversial, and no report supports NAC with a high evidence level. Recently, we showed that a deep surgical margin was resected very close to the tumor site in many NAC-treated oral squamous cell carcinoma patients, suggesting that NAC may lead to local recurrence and poor outcomes. The purpose of this study was to evaluate the effect of NAC ...
AIM To develop and validate a risk estimation of tumor recurrence following curative resection of operable hepatocellular carcinoma (HCC). METHODS Data for 128 patients with operable HCC (according to Barcelona Clinic Liver Cancer imaging criteria) who underwent preoperative computed tomography (CT) evaluation at our hospital from May 1, 2013 through May 30, 2014 were included in this study. ...
Aim: To assess the outcome of germ cell tumors in children after surgical management.
 Study Design: A longitudinal study.
 Place and duration: Pediatric surgery oncology department national institute child health Karachi from January 2017 to December 2018.
 Methodology: total 79 between ages 0 12 years were included study. Baseline, ultrasound, CT scan, tumor markers, biopsy for...
UNLABELLED Breast cancer mortality is principally due to tumor recurrence; however, the molecular mechanisms underlying this process are poorly understood. We now demonstrate that the suppressor of cytokine signaling protein SPSB1 is spontaneously upregulated during mammary tumor recurrence and is both necessary and sufficient to promote tumor recurrence in genetically engineered mouse models. ...
Background & Aims: In addition to the clinical and histological factors that are able to differentiate between low grade tumors and high grade tumors in bladder urothelial tumors, a number of biomarkers have also been proposed that may be useful in evaluating tumor grade, outcome, and prognosis. The purpose of the present study was to investigate the relationship between the amount of Her2/neu ...
Medulloblastoma is a common pediatric tumor typically diagnosed before the age of fifteen. Initial therapy includes surgical resection and radiation of the entire neuro-axis. Recurrence is common and typically occurs within 2 years of initial diagnosis. Those fitting Collin's Law is considered tumor-free. We report a case of single supratentorial recurrence 13 years after initial diagnosis. Her...
BACKGROUND AND PURPOSE Our aim was to compare the CT and PET/CT imaging features of osteoradionecrosis with those of recurrent disease after treatment of head and neck malignancy. MATERIALS AND METHODS We retrospectively reviewed maxillofacial and neck CT scans obtained for suspected osteoradionecrosis or tumor recurrence for the presence of the following: 1) discrete solid mass, 2) cystic ma...
Bladder cancer has an unexplained, high recurrence rate. Causes of recurrence might include the presence of sporadic tumor micro-foci in the residual urothelial tissue after surgery associated with an inverted ratio between intratumoral effector and regulatory T cell subsets. Hence, surgical specimens of both tumors and autologous, macroscopically/histologically free-of-tumor tissues were colle...
