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...

Our work on stereotactic body radiation therapy (SBRT) for primary and metastatic lung tumors will be described. The eligibility criteria for SBRT, our previous SBRT method, the definition of target volume, heterogeneity correction, the position adjustment using four-dimensional cone-beam computed tomography (4D CBCT) immediately before SBRT, volumetric modulated arc therapy (VMAT) method for S...

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.

A cardiac myxoma, a rare but relatively common tumor, was surgically excised. Histopathological examination of the lesion revealed an extensive internal ossification. Ossification interior myxomas is rarely reported, and most are large tumors; however, this case small tumor. The cause ossification has not yet been clearly reported.

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...

INTRODUCTION Serum prostate specific antigen (PSA) concentration in localized prostate cancer (PCa) patients depends of numerous factors related to tumor, prostate and the patient. Tumor factors include tumor volume, localization, growth rate and aggressiveness. Prostate factors include prostate volume, the activity of dihydrotestosterone (DHT) and PSA synthesis. Host factors include androgenic...
