solitary plasmacytoma of bone is a rare malignant tumor mostly involving the axial skeleton. the tumor occurs in middle- aged or elderly people (mean age: 55 years) and has a high risk of progression to multiple myeloma. radiotherapy is the preferred treatment for this disease. we report a case of recurrent solitary plasmacytoma of the fourth lumbar vertebra in a 35-year-old male. the patient s...

background: inflammatory myofibroblastic tumor (imt) is a tumor composed of myofibroblasts and a mixed inflammatory infiltrate that rarely undergoes malignant transformation. the most common sites of involvement include the lung, liver and orbit, but it has been reported to occur in nearly every site of the body, including oral cavity and soft tissue. although common in other sites, such a tumo...

background: in megavoltage radiotherapy rooms, ordinary concrete is usually used due to its low construction costs, although higher density concrete are sometimes used, as well. the use of high-density concrete decreases the required thickness of the concrete barrier hence, its disadvantage is its high cost. in a nuclear reactor, neutron radiation is the most difficult to shield. a method for p...

despite all advances, treatment of esophageal carcinoma is still unsatisfactory. currently the standard non-surgical treatment of esophageal cancer is concurrent chemotherapy and radiotherapy (chemoradiation), with results comparable to best surgical series. a few years ago, we started a chemoradiation protocol for the cancer of esophagus as a curative treatment, of which we present the prelimi...

BACKGROUND There are no consistent agreements on whether radiotherapy after breast-conserving surgery (BCS) could provide local control and survival benefit for older patients with early breast cancer or breast ductal carcinoma in situ (DCIS). The present study aimed to evaluate the efficacy of radiotherapy after BCS in older patients with early breast cancer or DCIS. RESULTS Radiotherapy cou...

Abstract Background : To explore the correlations of cofilin1 (CFL1) and phosphorylation level locus serine residue at position 3 (Ser3) with sensitivity elderly patients non-small cell lung cancer (NSCLC) to radiotherapy. Methods A total 102 eligible treated from June 2013 April 2015 were selected. The cases complete remission partial included into radiotherapy-sensitive group (n=55), while th...

the effects of combined radiotherapy (rt) and chemotherapy in the severity of cytogenetic alterations expressed as micronucleus (mn) in peripheral blood lymphocytes of patients treated for esophageal cancer was evaluated. to do this, blood was obtained from 23 and 15 esophageal cancer patients scheduled for chemo-radiotherapy and rt alone, respectively, before, during, and after treatment. bloo...

the male breast cancer (mbc) is a very rare neoplasm which accounts for 0.5-1% of the total cases of breast cancer. bilateral involvement is reported to occur in fewer than 2% of all the diagnosed cases of mbc, and synchronous tumors are very rare. because of its rarity, little is known about mbc etiology, its clinical findings and treatment. most patients present with a painless breast mass. t...
