Filter by:A propensity- matched study was conducted to investigate the feasibility and safety of adding temozolomide to hypofractionated stereotactic radiotherapy for large brain metastases.
The goal of this trial is to evaluate the effect of the prone crawl treatment position and/or accelerated schedule on acute and late toxicities, as well as quality of life and time management for breast cancer patients receiving whole breast and regional nodal irradiation after breast conserving surgery.
This trial is a multicenter, perspective, non-blinded, randomized controlled phase 3 trial. In order to establish whether the SIB technique can improve the results of twice-daily chemo-RT for patients with LS-SCLC, the investigators will primarily compare survival of patients treated with standard chemotherapy (cisplatin and etoposide) and either SIB twice-daily RT or standard dose twice-daily RT.
Currently, cancer is a disease of high incidence, already considered a public health problem. Among the most prevalent are head and neck neoplasms, and depending on the location and extent of the lesion, the treatments are surgery, chemotherapy and / or radiotherapy that have a great impact on the quality of life. Radiation therapy is a frequently chosen treatment, and depending on the dose of radiation, causes changes such as hyposalivation. There are techniques for salivary flow stimulation, however, most of the options involve the use of medications, which limits administration to part of the patients. Transcutaneous electric nerve stimulation (TENS) is an alternative that has been used to stimulate salivary flow, however there is a limited number of studies that have tested this technique after radiotherapy. The aim of this study was to verify the effect of TENS in increasing the salivary flow of individuals receiving radiotherapy to treat tumors of the head and neck. The sample will have 80 patients randomly divided into two groups: TENS group and Control group. In both groups, a quality of life questionnaire (UW-QOL) will be applied and a speech-language assessment will be performed. The hypothesis of this research is that TENS is effective in increasing the amount of saliva. Secondary outcomes involve the evaluation of the effect of this technique on the quality of life, mainly in the questions: speech, chewing, saliva and deglutition.
About 89%-100% patients with head and neck malignant tumors have radiation mucositis during their radiotherapy. Until now, there is no effective method to prevent mucositis. Steroid hormone, pain-relief, anti-inflammatory and other symptom-relief treatments usually are used after the emergence of mucositis. Coixenol triglyceride is an ester extract of Coix Seed. Its trade name is Kanglaite Injection, which has been approved in China and Russia. Kanglaite has anti-tumor effect and reduce treatment toxicity of tumor. Kanglaite could also improve the quality of life of patients and mitigate the condition of the cachexia. In china, two studies evaluating treatment of Kanglaite to nasopharyngeal cancer, found that Kanglaite can reduce radiotherapy mucositis. So far, Kanglaite on the prevention and treatment of radiation mucositis of the head and neck malignant tumor is still lack of strong clinical trial evidence. This is a phase II, single center, one arm study with subject to evaluate the acute radiation mucositis, nutritional status, and quality of life on the course of radiotherapy of head and neck cancer.
An open-label, non-randomized study to assess the titration, safety and efficacy of intranasal fentanyl pectin nasal spray for the treatment of secondary breakthrough pain secondary to radiation-induced mucositis in patients with confirmed tolerance of opioid therapy for chronic pain. Study objectives include assessment of breakthrough pain episodes related with food intake in patients with mucositis secondary to radiotherapy or radio-chemotherapy for head and neck tumors
This study will evaluate the role of cyclooxygenase pathways in radiation-induced and chemoradiation-induced mucositis.
The purpose of this study is to: - estimate the degree of memory loss, if any following radiotherapy to the base of skull or brain as measured by standard neurocognitive battery testing. - describe radiotherapy dose-related changes in vascular perfusion, in spectroscopic parameters of neuronal injury and changes in the degree and directionality of tissue water diffusivity (diffusion tensor imaging) as a measure of white axonal injury. - to relate these imaging characteristics to the degree of memory loss.
Rationale: Dose escalation in external-beam irradiation has proven to benefit outcome in local prostate cancer. Randomized trials were performed up to doses of 78 Gy in 2 Gy fractions. Nevertheless, the five-year biochemical relapse rate still was approximately 35% in the high-dose arm. Therefore further dose escalation seems to be required. A feasibility study up to appr. 85 Gy on the entire prostate has already been performed and showed acceptable toxicity when combined with adequate position verification. Higher doses to the entire prostate are expected to increase severe toxicity. As local recurrences only occur at the site of the primary macroscopic tumour area the next step in increasing the dose should be an ablative boost to the macroscopic tumour alone, while electively irradiating the rest of the prostate to the current gold standard dose. Feasibility of this approach has been shown for an ablative dose of 95 Gy to the macroscopic tumour within the prostate.
Many breast cancer patients will taking Chinese herbal medicine during receiving radiotherapy. The investigators conducted the pilot study showing Compound Herbal Formula (TPE-1) have the effect of improving the fatigue and leukopenia during radiotherapy. So the investigators designed this double blind and controlled trial to evaluate whether TPE-1 have the effects for leukopenia and cancer-related fatigue in breast cancer patients with radiotherapy. From our initial observation for 2 years, TPE-1 is safety. The study is also designed to evaluate the safety when patients taking this formula.
