the primitive neuroectodermal tumor (pnet) belongs to a group of highly malignant tumors and is composed of small round cells of a neuroectodermal origin. categorized in the same tumor family as ewing sarcoma, the pnet is most likely to occur in bones and soft tissues. however, a small number of pnet cases arising in the pelvis have been reported as well. we present three cases of pelvic pnet: ...

Purpose To determine whether gross tumor volume of resectable gastric adenocarcinoma on multidetector computed tomography could predict presence of lymphovascular invasion and T-stages. Results Gross tumor volume increased with the lymphovascular invasion (r = 0.426, P < 0.0001) and T stage (r = 0.656, P < 0.0001). Univariate analysis showed gross tumor volume could predict lymphovascular inv...

OBJECTIVE To determine whether the gross tumor volume of resectable gastric adenocarcinoma on multidetector computed tomography could predict the presence of regional lymph node metastasis and could determine N categories. MATERIALS AND METHODS A total of 202 consecutive patients with gastric adenocarcinoma who had undergone gastrectomy 1 week after contrast-enhanced multidetector computed to...

PURPOSE This study evaluated the usefulness of tumor volume measurement with positron emission tomography (PET) in patients with advanced cervical cancer treated by radiation therapy. METHODS AND MATERIALS Fifty-one patients underwent PET before treatment. Primary tumor volume was determined, and volume, FIGO stage, and presence of lymph nodes on the PET study were compared to progression-fre...

AIM The study aimed to determine a prognostic value of primary tumor volume measured on the basis of integrated positron emission tomography-computerized tomography (PET-CT) in terms of mediastinal nodal metastases (N2) prediction in non-small-cell lung cancer (NSCLC) patients with PET-CT N2 negative lymph nodes. METHODS The records of 70 potentially operable NSCLC patients treated with surgi...

background: artemisia diffusa contains a new type of sesquiterpene lactone with an endoperoxide group (tehranolide). objective: due to the existing similarity between the structures of tehranolide and artemisinin, it was hypothesized that tehranolide would have similar effects as artemisinin. in this study, the immunotherapeutic effec-tiveness of tehranolide was investigated by direct intra-tum...

Background: Tumor volume doubling time (VDT) has been shown to predict prognosis in various non-small cell lung carcinoma with scant evidence for squamous (SCC). The purpose of this study was investigate the prognostic value tumor VDT resected SCCs.

OBJECTIVES To quantify the changes seen in the endorectal magnetic resonance imaging (erMRI)-defined prostate volume, predominant tumor volume, and secondary tumor volume during neoadjuvant total androgen suppression (TAS). METHODS Between July 1997 and April 2001, 152 consecutive patients with clinical Stage T1b-T3cNXM0 prostate cancer were treated with 6 months of TAS and external beam radi...
