the postgastrectomy recurrence rate is as high as 30-65%, with 5-year overall survival rates of <20%. local recurrence is very common which occurs in 38-45% of cases. the most common sites of locoregional recurrence are the gastric remnant at the anastomosis, the gastric bed, and the regional nodes. the recurrence may occur as early and late events after gastrectomy. most recurrences are early,...

most patients with gastrointestinal cancers refer to the health centers at advanced stages of the disease and conventional treatments are not significantly effective for these patients. therefore, using modern therapeutic approaches with lower toxicity bring higher chance for successful treatment and reduced adverse effects in such patients. the aim of this study is to evaluate the effect of av...

objective(s): in positron emission tomography (pet) studies, thoracic movement under free-breathing conditions is a cause of image degradation. respiratory gating (rg) is commonly used to solve this problem. two different methods, i.e., phase-gating (pg) and amplitude-gating (ag) pet, are available for respiratory gating. it is important to know the strengths and weaknesses of both methods when...

preoperative gleason score (gs) obtained from trans rectal ultra sonography (trus) is the most common grading system to evaluate the appropriate treatment for patients with clinically localized prostate cancer. but this method showed upgraded and downgraded results in comparison to gleason score obtained from radical prostatectomy. the current study aimed to determine clinical or pathological v...

After curative treatment of Hodgkin&rsquo;s lymphoma, increased risk of certain solid tumors has been reported. To best of our knowledge this is the first report of metachronous pancreatic adenocarcinoma which developed outside the previous radiation field in a patient with relapse Hodgkin&rsquo;s lymphoma. Herein we present an 81-year-old female who developed pancreatic adenocarcinoma four yea...

     The chloroform soluble fractions of ethanolic extracts of five Inula belonging to the Compositae family were evaluated for cytotoxic activity against five different cell lines including CACO2 (human colon adenocarcinoma), MCF7 (human breast adenocarcinoma), HEPG2 (human hepatocellular carcinoma), VERO (green African monkey kidney) and WEHI164 (balb c mouse fibrosarcoma). Cytotoxic...

 Endometrial adenocarcinoma is uncommon in fewer than 40-year-old people. The first common sign and symptoms are abnormal vaginal bleeding and discharge. Metastasis is occurred in the late stage. Here we present a 31-year-old nullipar woman who was admitted to surgical ward with enlarged right inguinal lymphnode from one month ago.

Intraoperative radiation therapy (IORT) is a multidisciplinary approach in which residual tumors or tumor beds are directly irradiated during a surgical procedure. To evaluate its efficacy, from 1985, we conducted a prospective study including non-metastatic gastric adenocarcinoma treated by surgery, IORT (15 Grays) and postoperative external beam radiotherapy (44 Grays). Up to 1993, 51 ca...
