Neck lymph node metastases from occult primary constitute about 5%-10% of all patients with carcinoma of unknown primary site. Metastases in the upper and middle neck (levels I-II-III-V) are generally attributed to head and neck cancers, whereas the lower neck (level IV) involvement is often associated with primaries below the clavicles. Diagnostic procedures include a careful clinical evaluati...

PURPOSE Desmoplastic small round cell tumor (DSRCT) is a rare aggressive malignancy that occurs in a young population with a male predominance. We studied the clinical and pathological characteristics of DSRCT and investigated the effects of multimodal therapy including aggressive surgical resection, induction chemotherapy, and external beam radiotherapy. METHODS We retrospectively reviewed a...

abdominal mass is one of the commonest clinical findings in children. the purpose of this study was to evaluate abdominal masses in different age groups in a referral children surgical center. we retrospectively reviewed records of 325 patients (57% boys, mean age 37.7 months) admitted to amir kabir hospital in period of 12 years for abdominal mass surgery. the 4 most common abdominal masses wa...

Exposure to ionizing radiation (IR) during procedures such as abdominal and pelvic radiotherapy results in severe intestinal injury. In the current study, we demonstrated that a lethal dose of IR triggered epithelial cell apoptosis pyroptosis via Caspase-3 cleavage. The ginseng active ingredients, ginsenosides (GS) phenolic acids (GPA), significantly inhibited IR-induced IEC-6 cells. GS GPA als...

background : we conducted a retrospective analysis to evaluate overall survival (oas) and disease free survival (dfs) rates in patients with squamous cell carcinoma of the urinary bladder according to different prognostic factors. methods : this retrospective study analyzed the medical records of patients with non-metastatic squamous cell carcinoma of the urinary bladder. all men underwent radi...

Intrafraction motion caused by breathing requires increased treatment margins for chest and abdominal radiotherapy and may lead to 'motion artefacts' in dose distributions during intensity modulated radiotherapy (IMRT). Technologies such as gated radiotherapy may significantly increase the treatment time, while breath-hold techniques may be poorly tolerated by pulmonarily compromised patients. ...

PURPOSE To evaluate the effectiveness and safety of postoperative radiotherapy for the treatment of keloid scars administered immediately after Cesarean section. MATERIALS AND METHODS A total of 26 postpartum patients with confirmed keloids resulting from previous Cesarean sections received either 12 or 15 Gy radiotherapy. The radiotherapy was divided into three 6 MeV electron beam fractions ...

BACKGROUND Desmoid tumors, which are associated with familial adenomatous polyposis (FAP), tend to occur frequently in the abdominal wall and mesentery. Currently, there are no recognized treatments other than surgery, and frequent surgeries result in gastrointestinal obstructions and functional gastrointestinal disorders. CASE PRESENTATION After surgery that was performed on a 39-year-old pa...

Primary hepatic lymphoma is a rare disorder representing less than 1% of all extranodal lymphomas. Histological examination of a primary hepatic lymphoma usually reveals a diffuse large B-cell lymphoma; there have been few reports of primary hepatic mucosa-associated lymphoid tissue (MALT) lymphomas. A 67-year-old man was being treated for a duodenal ulcer; while receiving therapy for the ulcer...

BACKGROUND Metastasis to the skin occurs rarely in gynecologic cancer, especially in cervical carcinoma. Although carcinoma of the cervix is the second to the fourth most common malignancy in women, cutaneous involvement originating from cervical cancer is particularly unusual, even in the terminal stage of the disease. CASE We present a case of cervical cancer recurrence with skin metastasis...
