Filter by:It aims to evaluate the efficacy of the chamomile recutita gel and urea cream in the prevention of radiodermatitis in patients with breast cancer or head and neck cancer undergoing radiotherapy. Prophylactic Trial will consist of a control group and two experimental groups, namely control group (usual care), Experimental Group 01 (usual care + topical application of the gel C. recutita) and Experimental Group 02 (usual care + topical application of Urea based cream). The doses used in the different compounds are being in test since february 2014 by a dose-response curve study, using 6 groups with three doses of urea cream and three doses of C. recutita gel. The study will be conducted at the Center for High Complexity Oncology at University Hospital of Brasília (CACON/HUB), Brazil. The degree of radiodermatitis is evaluated weekly, according to established criteria to classify the effects of radiotherapy, which identifies grades 0, 1, 2 , 3 and 4, according to the score of the Radiation Therapy Oncology Group - RTOG. To evaluate the skin reaction will also be applied scale Common Terminology Criteria for Adverse Events (CTCAE) and Radiation-Induced Skin Reaction Assessment Scale (RISRAS).
The aim of the study is to compare the effect of Roux-en Y reconstruction (study group, DPCDA) versus classical Child reconstruction (DPCUN) in the incidence of VGL in patients for DPC. The hypotesis of the study is that Roux-en Y reconstruction decreases incidence of DGE after pancreaticoduodenectomy.
This pilot research trial studies circulating tumor deoxyribonucleic acid (DNA) in predicting outcomes in patients with stage IV head and neck cancer or stage III-IV non-small cell lung cancer. Studying circulating tumor DNA from patients with head and neck or lung cancer in the laboratory may help doctors predict how well patients will respond to treatment.
Given that the cost of proton therapy is considerably higher than that of conventional radiotherapy with photons, it is necessary to establish whether these higher costs are worthwhile in light of the expected advantages2,3,4. Thus, clear evidence of the situations in which proton therapy outperforms conventional photon treatment is needed. The investigators therefore aim to demonstrate through an in silico trial that proton therapy decrease the amount of irradiated normal tissue and, consequently, the risk of side effects in the surrounding normal tissue as well as the risk of secondary tumors. The same overall treatment time and an equal number of fractions will be used for both treatment modalities wherever possible. The most optimal technique for each individual patient, based on objective criteria related to limiting dose to normal tissue, will be prescribed by the institution concerned for each treatment option.
Head and neck cancer corresponds to tumors located in the upper aerodigestive tract, such as the oral cavity, pharynx and larynx. The most effective treatment consists of high dose of cisplatin chemotherapy and radiotherapy, however, their use is limited due to toxicities caused mainly by oxidative stress. The objective of this study will be evaluate the use of n-acetylcysteine attenuating cisplatin-induced toxicities by oxidative stress in head and neck cancer patients. This is a randomized double-blind placebo-controlled clinical trial with consecutive sampling that will be conducted at Oncology Department of Clinic Hospital / University of Campinas (UNICAMP). Head and neck cancer patients who will begin cisplatin antineoplastic treatment (80-100mg/m2 on days 1, 22 and 43) and concurrent radiotherapy will be included in this research. They will be studied in 2 groups (n-acetylcysteine and placebo). All patients will be evaluated in relation to cisplatin induced hematologic and gastrointestinal disorders, nephrotoxicity, ototoxicity, and hepatotoxicity; plasmatic and cellular oxidative stress; quality of life; and pharmacoeconomic evaluation. Results will be statistically analysed using Chi-square, Fisher, Mann-Whitney, and ANOVA for repeated measures tests (p<0.05.)
Vasopressors may be needed after head and neck microvascular reconstructions to maintain sufficient mean arterial pressure. This is crucial for the flap survival. The study hypothesis is that norepinephrine and dopamine used as vasopressors do not affect flap tissue oxygen level and microdialysate metabolites.
To study the effect of Ganoderma Spores Powder Capsules on the life quality and immunity status of the patients with head-and-neck cancer after complete treatment (including surgery and / or radiotherapy and/or chemotherapy)
Prevention of critical weight loss. In patients with Squamous Cell Carcinoma of the Head and Neck (SCCHN) weight loss is a relevant clinical problem during radiotherapy and might result in higher treatment related toxicity and discontinuation of a potential curative treatment. Thus the investigators want to evaluate the efficacy of overnight parenteral nutritional (PN) support in patients with SCCHN treated with curative radiotherapy (RTX) in combination with Cetuximab (E) or Cisplatin (P).
Accelerated, normofractionated radiotherapy is the treatment of choice in stage II-III laryngeal and oropharyngeal squamous cell carcinoma (SCC). However, twenty to thirty percent of patients with stage II-III laryngeal and HPV negative oropharyngeal SCC develop disease progression, mainly due to lack of locoregional control. Radiosensitizers such as cisplatin and cetuximab are added to radiotherapy in more advanced stage of head and neck (H&N) cancer. These radiosensitizers improve loco-regional control and overall survival. Unfortunately, as these radiosensitizers, notably cisplatin, also dose intensify the radiation dose in normal tissues, they also significantly increase toxicity. Adding a more tumor-specific radiosensitizing agent could improve loco-regional control and overall survival without significantly increasing toxicity. Radiotherapy kills tumor cells by inducing DNA damage. The efficacy of radiotherapy is limited by the ability of tumor cells to repair this DNA damage. Poly(ADP-ribose)polymerase (PARP) is an essential enzyme in base excision repair and single strand break DNA repair, DNA lesions arising from radiation treatment. PARP inhibition and consequently the inhibition of PARP-facilitated DNA repair enhances the anti-tumor activity of radiotherapy, as shown in preclinical studies including head and neck xenograft studies. This radiosensitization is thought to be proliferation dependent and is more pronounced in homologous recombination (HR) deficient cells, providing an opportunity for tumor specific targeting. Genetic analyses suggest that HR deficiency is commonly found in H&N SCC: ATM loss has been reported in 60% of human H&N SCC biopsies and FANC-F defects were reported in 15-21% of human H&N SCC biopsies and cell lines. The efficacy of radiotherapy is also limited by tumor hypoxia, as tumor hypoxia results in radioresistance. Some PARP inhibiting compounds increase tumor perfusion in xenograft models, thereby reducing hypoxia and specifically sensitizing tumor cells to radiotherapy. Hypoxia is commonly found in H&N SCC and a high pre-treatment hypoxic fraction in H&N SCC tumors is associated with worse outcome. The high prevalence of both hypoxia and HR deficiencies in H&N SCC support the concept of tumor-specific radiosensitization by PARP inhibition in head and neck cancer patients. Olaparib is a potent PARP inhibitor developed as an anti-cancer drug for HR defected tumors and as a dose intensifier for chemo- and radiotherapy. In humans, olaparib has a low toxicity profile as a single agent, with increasing bone marrow toxicity when combined with chemotherapy. The combination of olaparib and radiotherapy for H&N SCC is expected to improve locoregional control and thereby overall survival. However, this combination treatment has never been tested in humans before. The purpose of this study is to determine the safety and tolerability of radiotherapy for stage II-III laryngeal and stage II-III HPV-negative oropharyngeal SCC with concurrent olaparib.
This is a Phase I multicenter, open-label, dose-escalation study of DTP348. DTP 348 is an oral dual drug with two mechanisms of action: 1. carbonic anhydrase IX inhibitor which acidifies the intracellular pH through the sulfamide components 2. radio sensitizer of hypoxic cells through its 5-nitroimidazole moiety The study will be conducted in 2 parts. The phase I trials will be on the standard 3+3 design first as single agent then combined with radiotherapy: 1. A single agent dose-escalation phase in patients with solid tumours. 2. A dose-escalation phase in patients with HNSCC in combination with radiotherapy The main objective is to determine the recommended phase II dose of DTP348 in combination with radiotherapy
