Combined Chemotherapy (combined + chemotherapy)
Selected AbstractsEpstein-Barr virus (EBV) serology for predicting distant metastases in a white juvenile patient with nasopharyngeal carcinoma and no clinical response to EBV lytic induction therapyHEAD & NECK: JOURNAL FOR THE SCIENCES & SPECIALTIES OF THE HEAD AND NECK, Issue 11 2006Servi J. C. Stevens PhD Abstract Background. We describe a case of a 16-year-old white girl with Epstein-Barr virus (EBV)-positive nasopharyngeal carcinoma (NPC). Methods. At diagnosis, the patient had characteristic immunoglobulin (Ig)A and IgG responses to EBNA1, viral capsid antigen (VCA)-p18, and early antigens (EAs), with no detectable EBV DNA in her blood. Combined chemotherapy and radiotherapy resulted in complete remission. Eighteen months later, the patient's IgA responses to EBNA1 and p18 and both IgA and IgG anti-EA increased, without apparent recurrence. Five months later, lung metastases were found. She underwent surgical removal of the lung metastases and conventional chemotherapy, but had intraabdominal lymph node metastasis and mediastinal lesions develop. The patient was then treated with a novel treatment consisting of 5-fluorouracil plus valproic acid and subsequent valganciclovir to induce lytic EBV replication. This resulted in the first detectable EBV DNA levels in the blood but did not result in clinical response. Results. The patient's disease progressed, and the patient declined further cancer treatment and died. Conclusion. In contrast to EBV DNA load, EBV serology was useful in predicting distant NPC metastasis after initial complete remission in this patient. © 2006 Wiley Periodicals, Inc. Head Neck, 2006 [source] Characteristics and prognosis of primary thyroid non-Hodgkin's lymphoma in Chinese patientsJOURNAL OF SURGICAL ONCOLOGY, Issue 7 2010Tuan-Qi Sun MD Abstract Background and Objectives There exists no universally accepted treatment for primary thyroid non-Hodgkin's lymphoma (TNHL) due to the rarity of this entity. The aim of this study is to assess the role of surgery and to explore prognostic factors in Chinese TNHL patients. Methods Patient presentations, pathologies, surgical interventions, multidisciplinary treatment, prognostic factors and the value of fine needle aspiration were analyzed. Results Between 1991 and 2007, 40 patients of TNHL were diagnosed. Thirty-eight patients underwent an initial surgical procedure. Further treatments consisted of radiotherapy or chemotherapy alone, and the majority of patients were treated with combined chemo-radiation. After a median follow-up of 95 months, the 5-year overall survival (OS) and relapse-free survival (RFS) was 82% and 74%, respectively. Survival curves showed no significant difference between therapeutic operations when compared with diagnostic operations. A univariate analysis showed both International Prognostic Index (IPI) and staging significantly influenced OS and RFS. In multivariate analysis, IPI was found to be the only prognostic factor. Conclusions Combined chemotherapy and radiotherapy may offer better outcome without the need for extensive resection, and surgery should be reserved to providing tissue for diagnosis. The patients with low-intermediate risk (IPI,=,2) or stage IIE need be treated more aggressively. J. Surg. Oncol. 2010; 101:545,550. © 2010 Wiley-Liss, Inc. [source] Chemotherapy: the effect of oral cryotherapy on the development of mucositisJOURNAL OF CLINICAL NURSING, Issue 6 2005erife Karagözo, lu MSc Aims and objective., The aim of this study is to investigate the effect of oral cryotherapy on the development of chemotherapy-induced mucositis in patients administered combined chemotherapy. Background., Mucositis has been of interest to scientists for more than 20 years. Unfortunately, this has not resulted in the development of standard procedures for prevention and management. To cope with this side-effect and to prevent opportunistic infections that may emerge during treatment, attempts are taken to provide preventative and comfort measures. In this context, cryotherapy (oral cooling) has become popular as a cheap and readily applicable method in preventing the developing due the rapid infusion of chemotherapy agents, or decreasing its severity. Design and method., Study involved 60 patients, 30 of whom were in the study group and 30 in the control group. Ice cubes at a size that can be moved easily in the mouth and whose corners have been smoothed in order that they will not cause irritation in the mouth has been used in oral cryotherapy in the study group. Oral chemotherapy was initiated five minutes before chemotherapy and maintained during venous infusions of etoposide (Vepesid®), platinol (Cisplatin®), mitomycin (Mitomycin-C®) and vinblastin (Velbe®) depending on the chemotherapy course. Results., According to Patient-Judged Mucositis Grading, the rate of mucositis is 36.7% in study group and 90.0% in control group, the difference between two groups being statistically significant (P < 0.05). According to Physician-Judged Mucositis Grading, the rate of mucositis is 10.0% in the study group and 50.0% in the control group, the difference between two groups being statistically significant (P < 0.05). Oral pH values decreased in 90% of the subjects in study group, i.e. mucositis risk was reduced whereas oral pH values remained unchanged or decreased in 86.7% of the subjects in the control group, namely mucositis risk increased. The difference between study and control groups in terms of the change in pH values after chemotherapy was found to be statistically significant (P < 0.05). Conclusion., Our findings have demonstrated that oral cryotherapy makes an important contribution to the protection of oral health by reducing the mucositis score according to patient- and physician-judged mucositis score and by increasing oral pH values. Relevance to clinical practice., Aggressive cancer therapy places patients at greater risk for oral complications and treatment-related consequences. Unfortunately, prevention and/or treatment of such oral sequelae have often become overlooked as priorities of the treatment team. Effective approaches for the prevention or treatment of oral mucositis have not been standardized, and vary considerably among institutions. Prophylactic measures begin with an increased emphasis on improved oral status. Oral cryotherapy, the therapeutic administration of cold, is a prophylactic measure for oral inflammation. The relevance for clinical practice will be to understand the content of mucositis; comprehensive care should focus on the prevention of this complication in the clinical practice. [source] Richter syndrome in B-cell chronic lymphocytic leukemiaPATHOLOGY INTERNATIONAL, Issue 4 2003Naoya Nakamura Richter syndrome (RS) is well known as a secondary high-grade lymphoma, mostly diffuse large B-cell lymphoma (DLBCL) developed in patients with B-cell chronic lymphocytic leukemia (B-CLL). In this review, we describe clinicopathological, histological, immunophenotypical and genetic findings of RS. The patients with RS, regardless of transformation of pre-existing clone or de novo malignant clone, were resistant to conventional combined chemotherapy and died within months of diagnosis. Molecular techniques can provide convincing results for the clonal relationship of RS to pre-existing B-CLL. When RS carries a same rearrangement band or a same sequence as B-CLL by Southern blotting or nucleotide sequence analyses of immunoglobulin heavy and/or light chain genes, it is suggested to that RS transforms from original B-CLL. These analyses have showed that approximately two-thirds of RS cases evolved from a B-CLL clone. How and where does the B-CLL clone evolve to RS? The genetic alteration of transforming B-CLL clone into RS has been addressed. Abnormalities of chromosomes 11 and 14 were most frequently involved in RS, but non-specific. In addition, RS does not include chromosomal translocation between Ig locus and oncogenes or rearrangements of bcl-6 gene, both of which were found in some de novo DLBCL. Several candidates, such as mutation of p53 gene and abnormalities of cyclin dependent kinase inhibitor, have been proposed to play an important role in the transformation of a part of B-CLL. However, there is still uncertainly as to how B-CLL progresses or develops into RS. [source] | ||||||||||
