Treatment of Esthesioneuroblastoma and Nonsmall Cell Lung Cancer with Phenylbutyrate

Journal of Cancer Therapy 2011年第4期2卷 518-522页

作者： Stanislaw R. Burzynski eva nagy-kubove 不详

Esthesioneuroblastoma is a malignant tumor, arising in the upper nasal cavity, that could spread to the frontal lobe of the brain as well as metastasize to the lymph nodes. Due to the low incidence of this tumor, FDA-approved treatment modalities do not exist and clinical trials have not been performed. We present an interesting case of a 66-year-old female, diagnosed with Kadish stage B esthesioneuroblastoma and stage IIA nonsmall cell carcinoma of the lung, who benefited from our treatment. Both malignancies were diagnosed in 2002 at which time the patient consented to undergo left upper lobectomy for her lung cancer, but she refused the craniofacial resection and radiation therapy recommended for treatment of her esthesioneuroblastoma. From 2003 to 2004 she received treatment at the Burzynski Clinic with oral sodium phenylbutyrate (0.2 g/kg/day). She tolerated the treatment very well without significant adverse events. Gradual reduction in her tumor size was confirmed by repeat MRIs. From treatment start in March 2003 to December 2003 her tumor decreased by 40%. Subsequent MRI from March 2004 revealed increased tumor size, which, however, was still a 13% reduction from the baseline MRI. What is important to mention is that in addition to shrinkage of the esthesioneuroblastoma, the patient obtained the clinical benefit of 3.5-years longer survival than was predicted for her lung cancer—whereas the median survival for a patient with stage IIA adenocarcinoma of the left upper lobe of the lung is approximately two years, our patient survived more than five and a half years. The effect of phenylbutyrate (PB) and its metabolite phenylacetate on neuroblastoma and lung cancer is documented by numerous preclinical studies and is also evident in this case. It is proposed that the activity of these two compounds is mediated through increased expression of the p21 tumor suppressor gene. p21 is a strong inhibitor of cyclin-D and cyclin-dependent kinase 4, which contribute to

Successful Treatment of Recurrent Triple-Negative Breast Cancer with Combination of Targeted Therapies

引用

Journal of Cancer Therapy 2011年第3期2卷 372-376页

We present an interesting case of a 56-year-old female diagnosed with invasive high-grade triple-negative breast cancer, who developed diffuse liver metastases following lumpectomy and combination chemotherapy with docetaxel, doxorubicin and cyclophosphamide, re-excision and radiation therapy. Restaging CT and PET scans revealed massive involvement of the liver. She was treated with a combination of gene targeted and cytotoxic chemotherapy including capecitabine, erlotinib, bevacizumab and phenylbutyrate. She tested weakly positive for HER-2 despite prior negative FISH, which prompted us to add trastuzumab to her regimen. Baseline CT revealed five liver tumors—the sum of the products of the two largest perpendicular diameters was 110 cm2. Follow-up CT after three months of treatment revealed 62% decrease in total tumor load. More than 50% decrease in tumor size persisted on two follow-up CT scans, confirming partial response. She developed progressive disease after 15 months of treatment. A group of 16 women, including this patient, diagnosed with triple negative breast cancer with distant metastases were treated by our team with a combination of gene targeted therapy and chemotherapy. Six percent of patients obtained partial response, 25% minor response, 31% stable disease, and 38% progressive disease. The median duration of treatment in patients who relapsed after the second-, third- and fourth- to seventh-lines of chemotherapy was 59 weeks, 22 weeks and 17 weeks, respectively. Comparison of results obtained with cytotoxic chemotherapy revealed that MDT in the second- and third-lines was only nine and four weeks, respectively. In conclusion, this case report indicates that it is possible to obtain durable objective response of recurrent TNBC with a combination of gene targeted agents.

Successful use of adalimumab for treating fistulizing Crohn's disease with pyoderma gangrenosum:Two birds with one stone

引用

World Journal of Gastroenterology 2009年第18期15卷 2293-2295页

作者： eva Zold Arpad nagy Katalin Devenyi Margit Zeher Zsolt Barta Division of Clinical Immunology 3rd Department of MedicineMedical and Health Science CenterUniversity of DebrecenDebrecen 4004Hungary Euromedic Diagnostics Szeged Kft Debrecen 4004Hungary

Crohn＇s disease （CD） is a chronic relapsing and remitting autoinflammatory disorder of the gastrointestinal tract that has many intestinal and extraintestinal complications. The purpose of treatment is long-term remission, reduction of complications, and improvement of patients＇ quality of life. In many cases, this can be quite challenging and it is necessary to have a well thought out management strategy. We present the case of a 38-year-old woman with fistulizing CD that manifested as diffuse abdominal pain and bloody diarrhea accompanied by arthralgia. In addition, there were ulcerative lesions surrounded by cutaneous inflammation and erythema on her extremities, indicative of pyoderma gangrenosum. The patient was treated with high doses of parenteral methylprednisolone without any improvement and was started on adalimumab. A positive response to adalimumab therapy was observed： after 2 mo of therapy, the ulcerative skin lesion healed completely and the enterogastric fistula was closed affcer 5 mo adalimumab treatment. Adalimumab might be a suitable initial as well as maintenance therapy in patients with complicated CD.

A case of interstitial pneumonitis in a patient with ulcerative colitis treated with azathioprine

World Journal of Gastroenterology 2007年第2期13卷 316-319页

作者： Ferenc nagy Tamas Molnar eva Makula Ildiko Kiss Peter Milassin eva Zollei Laszlo Tiszlavicz Janos Lonovics First Department of Medicine University of Szeged Faculty of Medicine Szeged Hungary Department of Radiology University of Szeged Faculty of Medicine Szeged Hungary Medical Intensive Care Unit University of Szeged Faculty of Medicine Szeged Hungary Institute of Pathology University of Szeged Faculty of Medicine Szeged Hungary

The early hypersensitivity reaction and late bone marrow depression are well-known side-effects of azathioprine, whereas interstitial pneumonia is a rare complication. A 40-year old male patient had been treated with azathioprine in consequence of extensive ulcerative colitis for 10 years. He then complained of 7 d of fever, cough and catarrhal signs, without symptoms of active colitis. Opportunistic infections were ruled out. The chest X-ray, CT and lung biopsy demonstrated the presence of interstitial inflammation. Azathioprine therapy was discontinued as a potential source of the pulmonary infiltrate. In response to steroid therapy, and intensive care, the pulmonary infiltrate gradually decreased within 4 wk. Three months later, his ulcerative colitis relapsed, and ileo-anal pouch surgery was performed. In cases of atypical pneumonia, without a proven infection, azathioprine-associated interstitial pneumonitis may be present, which heals after withdrawal of the drug.
