The role of radiotherapy in intracranial hemangiopericytoma/solitary fibrous tumors : A Turkish Society for Radiation Oncology Central Nervous System Tumors Group Study (TROD 07-008).

Objective: Intracranial hemangiopericytomas (HPC) are rare tumors. Radiotherapy (RT) is frequently performed after surgery, depending on tumor size, location, and the type of resection. Moreover, RT is preferred as an effective treatment for local recurrence and metastasis.

A novel prognostic biomarker in progression free survival for patients with cervical cancer, glucose to c-reactive protein ratio (GCR).

Background: Cervical cancer is a tumor with high morbidity and mortality. The importance of inflammatory and metabolic parameters affecting progression-free survival (PFS) and overall survival (OS) has been investigated more intensively recently. We aimed to investigate the effect of glucose/c-reactive protein (CRP) ratio [GCR], which shows these two parameters together, on PFS in cervical cancer.

The role of melatonin in preventing radiation-induced intestinal injury.

Purpose: Despite the therapeutic effects of radiotherapy on tumor cells, it has potential severe adverse effects on the surrounding normal tissues. Acute or chronic intestinal adverse effects that are likely to occur in patients undergoing radiotherapy for pelvic and abdominal cancers lead to increased morbidity, significant impairment of the quality of life, and economic losses. Various biological, chemical and pharmacological agents are being tested to protect from and to treat radiation enteritis.

Comparision of Radiochemotherapy Applications that Committing with Two Different Chemotherapies Route in Locally Advanced Lung Cancer.

Objective: This study investigated pre- and post-treatment tumor and lymph node dimension response rates and differences between side-effect profiles in patients with locally advanced inoperable nonsmall-cell lung cancer (NSCLC) receiving radiotherapy (RT) and concurrent chemotherapy (CT).

Materials And Methods: A total of 30 inoperable patients who had not previously received RT and having a mean age of 58.73±8.

Dose-dependent effect of radiation on resorbable blast material titanium implants: an experimental study in rabbits.

Background: Radiotherapy is a commonly used treatment modality in head and neck cancer; however, it also negatively affects healthy structures. Direct damage to oral soft and hard tissue frequently occurs with radiotherapy. In this study, we aimed to evaluate the effect of radiotherapy on bone surrounding titanium dental implants via biomechanical and molecular methods.

Carnitine and Adiponectin Levels in Breast Cancer after Radiotherapy.

Unlabelled: In this study, serum carnitine (CRNT) and adiponectin (APN) levels and the correlation of these parameters in patients with breast cancer before and after treatment with radiotherapy (RT) were determined.

Materials And Methods: Serum adiponectin and carnitine levels were assessed in 58 patients with breast carcinoma and 30 control subjects. Serum carnitine and APN levels were determined using a specific enzyme-linked immunosorbent assay.

The Use of Breast Magnetic Resonance Imaging Parameters to Identify Possible Signaling Pathways of a Serum Biomarker, HE4.

Objectives: This study aimed to investigate the relationship between breast magnetic resonance imaging (MRI) parameters; clinical features such as age, tumor diameter, N, T, and TNM stages; and serum human epididymis protein 4 (HE4) levels in patients with breast carcinoma and use this as a means of estimating possible signaling pathways of the biomarker, HE4.

Methods: Thirty-seven patients with breast cancer were evaluated by breast MRI and serum HE4 levels before therapy. Correlations between parameters including age, tumor diameter T and N, dynamic curve type, enhancement ratio (ER), slope washin (S-WI), time to peak (TTP), slope washout (S-WO), and the serum level of HE4 were investigated statistically.

Cystic isolated lymphoma of the base of the tongue: A case report.

Isolated lymphoma of the base of the tongue is a relatively rare condition. The clinical presentation may vary from a submucosal mass with a cystic appearance to an ulcerated lesion. In the present case, a cystic mass was identified in a patient admitted with a sore throat.

Are We Late in the Diagnosis of Malignities Occurring in Solid Organ Transplant Patients? 11 Years' Experience.

Objective: Our aim is to evaluate the frequency and characteristics of cancer in the population of patients with solid organ transplant who are under immunosuppressive medication. In this study we aimed to emphasize the importance of early diagnosis of cancer in solid organ transplant recipients. An aging population began to receive solid organ transplantation and survival times prolonged.

Estimation of the efficacy of chemo-radiotherapy on tumor regression in the patients with laryngeal cancer via computerized tomography using the Cavalieri method.

Conclusion: Calculating tumor volume using the Cavalieri method in laryngeal tumors before and after treatment may be useful to optimize the treatment and to minimize the side-effects of radiotherapy.

Purpose: This study aimed to estimate the pre-treatment and post-treatment tumor volumes of the patients to whom radiotherapy or radio-chemotherapy was applied as a treatment using Cavalieri's Principle as a stereological method and to assess tumor regression rates in the patients with Laryngeal Squamous Cell Carcinoma (LSCC) statistically.

Materials And Method: Sixteen patients (eight patients with stage T3 and eight patients with stage T4) diagnosed with LCCC bearing the appropriate characteristics to criteria in the otorhinolaryngology clinic were included.

Efficacy of manual lymphatic drainage and intermittent pneumatic compression pump use in the treatment of lymphedema after mastectomy: a randomized controlled trial.

Background: This study has two aims. The first was to investigate the efficacy and contribution of an intermittent pneumatic compression pump in the management of lymphedema, and the second was to evaluate the correlation of our measurement methods.

Methods: This study was designed as a controlled clinical trial at the Physical Medicine and Rehabilitation Department of Ataturk University Faculty of Medicine.

Effect of mirtazapine on MNNG-induced gastric adenocarcinoma in rats.

Objective: In this study, anticancer effects of mirtazapine on rats were investigated in an adenocarcinoma model induced by N-methyl-N-nitro-N-nitrosoguanidine (MNNG) and compared with those of cisplatin.

Materials And Methods: For this purpose, 10 mg/kg doses of mirtazapine were administered orally to one group of rats, while 1 mg/kg doses of cisplatin were administered intraperitoneally to another group. At 1 hour after administration, 200 mg/kg doses of MNNG were given orally to both groups.

Rhabdomyosarcoma of the oral cavity: a case report.

Rhabdomyosarcoma (RMS), a tumor of skeletal muscle origin, is the most common soft tissue sarcoma encountered in childhood and adolescence. The common sites of occurrence are the head and neck region, genitourinary tract, retroperitonium, and, to a lesser extent, the extremities. In the head and neck region, the most commonly affected sites are the orbit, paranasal sinuses, soft tissues of the cheek, and the neck.

The effects of zinc sulfate on the levels of some elements and oxidative stress occurring in lenses of rats exposed to total cranium radiotherapy.

Objective: There is currently substantial clinical interest in zinc (Zn) as an antioxidant and a protective agent against radiation-related normal tissue injury. To further assess the potential antioxidative effects, the effects of Zn were studied in rat lenses, a model of radiation-induced oxidative stress.

Materials And Methods: Sprague-Dawley rats were divided into three equal groups.
