  1. Non-surgical management of stage I lung cancer

    Gore, Elizabeth M.

    2010-01-01

    Stage I lung cancer has a high cure rate with surgery, although many patients are not surgical candidates due to comorbid conditions. Historically, non-operative treatment has been disappointing. New and promising ablative therapies offer a curative option.

  2. Triaging early-stage lung cancer patients into non-surgical pathways: who, when, and what?

    Sroufe, Rameses; Kong, Feng-Ming

    2015-01-01

    More lung cancer patients are being diagnosed at an earlier stage due to improved diagnostic imaging techniques, a trend that is expected to accelerate with the dissemination of lung cancer screening. Surgical resection has always been considered the standard treatment for patients with early-stage non-small cell lung cancer (NSCLC).

    More lung cancer patients are being diagnosed at an earlier stage due to improved diagnostic imaging techniques, a trend that is expected to accelerate with the dissemination of lung cancer screening. Surgical resection has always been considered the standard treatment for patients with early-stage non-small cell lung cancer (NSCLC). However, non-surgical treatment options for patients with early-stage NSCLC have evolved significantly over the past decade with many new and exciting alternative treatments now available. These alternative treatments include radiofrequency ablation (RFA), microwave ablation (MWA), percutaneous cryoablation therapy (PCT), photodynamic therapy (PDT) and external beam radiation therapy (EBRT), including stereotactic body radiation therapy (SBRT) and accelerated hypofractionated radiation therapy. We describe the established alternatives to surgical resection, their advantages and disadvantages, potential complications and efficacy. We then describe the optimal treatment approach for patients with early-stage NSCLC based on tumor operability, size and location. Finally, we discuss future directions and whether any alternative therapies will challenge surgical resection as the treatment of choice for patients with operable early-stage lung cancer.

    Full Text Available BACKGROUND Fissure in ano is a common painful anorectal condition with high recurrence rates. It is commonly seen due to sedentary lifestyle, which involves prolonged sitting posture, mental stress, low fiber diet and lack of physical activity which causes chronic constipation. Irrespective to whichever modality of existing therapies that are used, the recurrences are common. The traditional surgical option like lateral internal sphincterotomy, which has been into practice since long time carries risk of incontinence. It is a need of an hour to rely on a treatment modality which should be simple, safe, effective and reversible with no permanent sequelae. In this study chemical sphincterotomy using injection, Botulinum toxin gives an alternative modality and proved to be the most safe and reliable non-operative option for treating both acute and chronic fissure in ano. AIM AND OBJECTIVE This present study clinically assesses the role of injection Botulinum Toxin A in the management of acute and chronic anal fissure. METHODS A total of 50 patients including both acute and chronic fissure-in-ano were treated with injection Botulinum toxin as first line of management. RESULT All patients were found to get symptomatic relief with high rates of fissure healing eventually. The lack of complications and simplicity in its administration makes it a reliable alternative to the currently practiced therapies. CONCLUSION Botulinum toxin offers a simple outpatient procedure for fissure-in-ano, which is safe without any significant complications. It carries the potential of being used as a first line of management in acute and chronic fissure-in-ano.

  5. Non-surgical contraindication for acute appendicitis with secondary thrombocytopenia: a case report.

    Zhang, Hai-Hong; Gu, Guo-Li; Zhang, Xiang-Yang; Fan, Qin; Wang, Xin-Yan; Wei, Xue-Ming

    2015-03-01

    A 26-year-old man presented with migrated right lower abdominal pain and without any history of hematological systemic diseases. Blood routine test showed a leukocyte count of 22.74 × 10(9)/L, with 91.4% neutrophils, and a platelet count of 4 × 10(9)/L before admission. The case question was whether the team should proceed with surgery. Obviously, a differential diagnosis is essential before making such a decision. Acute appendicitis was easily diagnosed based on clinical findings, including migrating abdominal pain, a leukocyte count of 22.74 × 10(9)/L and the result of abdominal computed tomography scan. However, it was not clear whether the severe thrombocytopenia was primary or secondary. So smear of peripheral blood and aspiration of bone marrow were ordered to exclude hematological diseases. Neither of the tests indicated obvious pathological hematological changes. There was no hepatosplenomegaly found by ultrasound examination of the liver and spleen. Therefore, operative intervention may be a unique clinical scenario in acute severe appendicitis patients with secondary thrombocytopenia. PMID:25759558

  8. Advances in imaging and in non-surgical salvage treatments after radiorecurrence in prostate cancer: what does the oncologist, radiotherapist and radiologist need to know?

    In this article the state of art the of prostate cancer (Pca) imaging and non-surgical salvage treatments (STs) is surveyed in order to explore the impact of imaging findings on the identification of radiorecurrent Pca after external beam radiotherapy (EBRT). A computerised search was performed to identify all relevant studies in Medline up to 2012. Additional articles were extracted based on recommendations from an expert panel of authors. Definitive EBRT for Pca is increasingly used as treatment. After radiorecurrent Pca, non-surgical STs are emerging and shifting from investigational status to more established therapeutic options. Therefore, several scientific societies have published guidelines including clinical and imaging recommendations, even if the timing, efficacy and long-term toxicity of these STs have to be established. In some measure, accurately delineating the location and the extent of cancer is critical in selecting target lesions and in identifying patients who are candidates for STs. However, there is increasing awareness that anatomical approaches based on measurements of tumour size have substantial limitations, especially for tumours of unknown activity that persist or recur following irradiation To date, the main focus for innovations in imaging is the combination of excellence in anatomical resolution with specific biological correlates that depict metabolic processes and hallmarks at the tumour level. The emergence of new molecular markers could favour the development of methods that directly determine their presence, thereby improving tumour detection. (orig.)

  9. Multi-transcript profiling in archival diagnostic prostate cancer needle biopsies to evaluate biomarkers in non-surgically treated men

    Kachroo, Naveen; Warren, Anne Y; Gnanapragasam, Vincent J.

    2014-01-01

    Background Most biomarkers in prostate cancer have only been evaluated in surgical cohorts. The value of these biomarkers in a different therapy context remains unclear. Our objective was to test a panel of surgical biomarkers for prognostic value in men treated by external beam radiotherapy (EBRT) and primary androgen deprivation therapy (PADT). Methods The Fluidigm® PCR array was used for multi-transcript profiling of laser microdissected tumours from archival formalin-fixed diagnostic biop...

    Background: No study to test the feasibility and prognostic value of the number of primary tumors, the number of positive lymph nodes, and the total number of tumors in the whole body as tumor burden measurements on FDG PET/CT imaging has been reported. Purpose: To determine whether the number of tumors seen in 18F-FDG PET scans can be a prognostic factor in non-surgical patients with non-small cell lung cancer (NSCLC). Material and Methods: One hundred and forty patients with histologically proven NSCLC and baseline 18F-FDG PET scan before therapy were identified in this retrospective analysis. The total number of tumors (TTn) in the whole body, the number of primary tumors (Tn), positive lymph nodes (Nn), and distant metastases (Mn), along with the maximum standardized uptake values (SUVmax) of the tumors were measured. Inter-observer variability of the total number of tumors, counted by two radiologists, was assessed. Survival analyses were performed to determine the prognostic value of the number of tumors. Results: Concordance correlation coefficients for the TTn, Tn, Nn, and Mn were all greater than 0.85. TTn and Nn were strong prognostic factors of NSCLC patients' overall survival (OS). In univariate Cox regression models, gender, stage, TTn, Nn, and Mn were statistically significant factors (P = 0.016, 0.032, <0.001, <0.001, and 0.006, respectively). In multivariate Cox regression models, TTn and Nn remained as statistically significant predictors for survival with hazard ratios (HR) of 1.06 (P = 0.001) and 1.11 (P = 0.002), respectively, after adjusting for clinical stage based 7th edition of TNM staging system, age, gender, and SUVmax. Patients with a TTn {<=}4 (cutpoint based on median value) had a median OS of 15.2 months compared with 9.0 months for those with TTn >4. Conclusion: Measuring the number of tumors on FDG PET imaging is easy to perform with minimal inter-observer variability. The total number of tumors and number of nodal metastases

    AimTo present our single-centre prospective experience on the use of cryoablation (CA) applied to treat primary breast cancer (BC) in a cohort of patients unsuitable for surgical treatment.Materials and MethodsTwenty-three consecutive post-menopausal female patients (median age 85 years; range 56–96) underwent percutaneous CA of unifocal, biopsy-proven BC, under ultrasound/computed tomography (US/CT) guidance. Clinical and dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) follow-ups were systematically scheduled at 3, 12, 18 and 24 months. Local tumour control was assessed by comparing baseline and follow-up DCE-MRI.ResultsTwenty-three BC (median size 14 mm) were treated under local anaesthesia (78.3 %) or local anaesthesia and conscious sedation (21.7 %). Median number of cryo-probes applied per session was 2.0. A “dual-freezing” protocol was applied for the first ten patients and a more aggressive “triple-freezing” protocol for the remaining 13. Median follow-up was 14.6 months. Five patients recurred during follow-up and two were successfully re-treated with CA. Five patients presented immediate CA-related complications: four hematomas evolved uneventfully at 3-month follow-up and one skin burn resulted in skin inflammation and skin retraction at 3 and 12 months, respectively.ConclusionsPercutaneous CA is safe and well tolerated for non-resected elderly BC patients. Procedures can be proposed under local anaesthesia only. Given the insulation properties of the breast gland, aggressive CA protocols are required. Prospective studies are needed to better understand the potential role of CA in the local treatment of early BC.

    急性踝关节扭伤是骨伤科常见的疾病,发病原因虽然单一,但在临床上却较为多见,加之其发病的年龄段跨度较大,扭伤后症状较重,越来越引起临床医生及其他学者的关注。该文就急性踝关节扭伤的非手术疗法治疗进展进行简要介绍。%As a common orthopedic diseases, acute ankle sprain is more common in clinical practice although it is caused by sin-gle etiologic factor. There are large age span and severe symptoms in the patients suffering from it, therefore it is paid attention to by more and more clinicians and scholars. The article briefly describes the progress of non-surgical therapy for this kind of dis-ease.

  14. Shoulder morbidity after non-surgical treatment of the neck

    Background and purpose: Reports on shoulder function after non-surgical treatment are not available. In the present study shoulder morbidity after surgical and non-surgical treatment of the neck is determined and compared. Materials and methods: In 100 head and neck cancer patients 174 neck sides were treated by surgery (n = 51) or (chemo)radiation (n = 123). Abduction, anteflexion, endorotation and exorotation were assessed. Subjective measurements were performed using the Visual Analogue Scale for pain, the Shoulder Disability Questionnaire (SDQ) and stiffness reporting. Results: Predictive factors for SDQ-score > 0 (n = 54) were VAS pain score, stiffness, abduction, anteflexion, physiotherapy, low shoulder position and surgical treatment. The SDQ, stiffness and pain scores were significantly higher in the surgically treated group than in the non-surgical group (p < 0.01). Anteflexion, abduction and exorotation were less impaired in the non-surgically treated group than in the surgically treated group (p < 0.01). No differences between neck dissection and neck dissection with post-operative radiotherapy, and radiotherapy and chemoradiation were found for these movements. Conclusions: Shoulder morbidity is often present after non-surgical treatment of the neck, but to a lesser extent compared to surgical treatment. Radiotherapy adds no morbidity to neck dissection and chemotherapy does not add extra morbidity to primary radiation

  15. Non-surgical breast-conservation treatment (KORTUC-BCT) using a new image-guided, enzyme-targeted, and breast cancer stem cell targeted radiosensitization treatment (KORTUC II) for patients with stage I or II breast cancer

    Tumor tissue can be re-oxygenated by inactivating peroxidase/catalase in the tumor tissue through application of hydrogen peroxide. The hydrogen peroxide in turn is then degraded to produce oxygen. In this way, low-LET (linear energy transfer) radioresistant tumors can be transformed into radiosensitive ones (Ogawa Y, et al: Int J Mol Med 12: 453-458, 845-850, 2003, Ogawa Y, et al: Int J Mol Med 14: 397-403, 2004, Kariya S, et al: Int J Radiat Oncol Biol Phys 75: 449-454, 2009). The purpose of the present study was to establish a non-surgical breast-conservation treatment (KORTUC-BCT) by utilizing a novel Kochi Oxydol-Radiation Therapy for Unresectable Carcinomas, Type II (KORTUC II) radiosensitization treatment. KORTUC I was shown to remarkably enhance radiotherapeutic effects in various types of superficially exposed and locally advanced neoplasms (Ogawa Y, et al: Oncol Rep 19: 1389-1394, 2008). Based on clinical experiences using KORTUC I, a new radiosensitizing agent containing hydrogen peroxide and sodium hyaluronate has been developed for intra-tumoral injection in various tumors which are not superficially exposed. The agent is composed of 0.5% hydrogen peroxide and 0.83% sodium hyaluronate (CD44 molecule). Sodium hyaluronate mixed with hydrogen peroxide attaches to CD44-positive tumor cells, which are generally reported to be breast cancer stem cells. This new method, named KORTUC II, was approved by our local ethics committee for treatment of advanced skin cancer (including malignant melanoma), bone/soft tissue malignant neoplasm, breast cancer and metastatic lymph node. A total of 39 early stage breast cancer patients (stage I: 12 patients and stage II: 27) were enrolled in the KORTUC II trial upon fully informed consent. Mean age of the patients was 61.1 years old. All 39 patients were unable or unwilling to undergo surgery and therefore undertook non-surgical breast-conservation treatment (KORTUC-BCT) by KORTUC II. A maximum of 6 ml of the agent was

  16. Non-surgical therapy of Peyronie's disease

    Frederick L. Taylor; Laurence A. Levine

    2008-01-01

    The present paper provides a review of the available non-surgical treatments for Peyronie's disease (PD). A review of published literature on oral, intralesional, external energy and iontophoresis therapies for PD was performed,and the published results of available treatment options reviewed. The authors' recommendations for appropriate non-surgical management of PD are provided. Although there are many published reports that show the efficacy of non-surgical therapies for PD, there is a lack of large scale, multicenter controlled clinical trials, which makes treatment recommendations difficult. Careful review of the literature does suggest that there are treatment options that make scientific sense and appear to stabilize the disease process, reduce deformity, and improve function. Offering no treatment at all will encourage our patients to pursue alternative treatments, which might do harm, and misses the opportunity to do some good. Clearly further work is necessary to develop safe and effective non-surgical treatments for PD.

  17. Percutaneous Lung Thermal Ablation of Non-surgical Clinical N0 Non-small Cell Lung Cancer: Results of Eight Years’ Experience in 87 Patients from Two Centers

    PurposeTo evaluate the survival outcomes of percutaneous thermal ablation (RFA + microwaves) for patients presenting N0 non-small-cell lung cancer (NSCLC) ineligible for surgery.Materials and MethodsEighty-seven patients from two comprehensive cancer centers were included. Eighty-two patients were treated with RFA electrodes and five with microwave antenna. Overall survival (OS) and disease-free survival (DFS) were estimated and predictive factors of local tumor progression, OS and DFS identified and compared by univariate and multivariate analysesResultsMedian follow-up was 30.5 months (interquartile range 16.7–51) and tumor size was 21 mm (range 10–54 mm). Treatment was incomplete for 14 patients with a local tumor progression of 11.5, 18.3, and 21.1 % at 1, 2, and 3 years, respectively. Two patients presented with neurological (grade III or IV) complications, and one died of respiratory and multivisceral failure as a result of the procedure at 29 days. In univariate analysis, increasing tumor size (P = 0.003) was the only predictive factor related to risk of local tumor progression. 5-year OS and DFS were 58.1 and 27.9 %, respectively. Sex (P = 0.044), pathology (P = 0.032), and tumor size >2 cm (P = 0.046) were prognostic factors for DFS. In multivariate analysis, pathology (P = 0.033) and tumor size >2 cm (P = 0.032) were independent prognostic factors for DFS.ConclusionsOversized and overlapping ablation of N0 NSCLC was well tolerated, effective, with few local tumor progressions, even over long-term follow-up. Increasing tumor size was the main prognostic factor linked to OS, DFS, and local tumor progression

  18. Measurement of tumor volume by PET to evaluate prognosis in patients with advanced non-small cell lung cancer treated by non-surgical therapy

    Background: Patients with advanced non-small cell lung cancer (NSCLC) seem to have disparity in prognosis. Accurate prediction of prognosis could be useful in the future to predict individual risk and to develop more aggressive or alternative treatment strategies. Purpose: To evaluate the prognostic value of metabolic tumor volume (MTV) measured by 18F-fluorodeoxyglucose positron emission tomography (18F-FDG PET) in patients with NSCLC. Material and Methods: We retrospectively reviewed 120 patients with pathologically proven NSCLC (61 squamous cell carcinomas and 59 adenocarcinomas) who underwent pretreatment 18F-FDG PET. MTV and maximum standardized uptake value (SUVmax) for the primary tumors were measured by 18F-FDG PET. Pretreatment variables (age, sex, American Joint Committee on Cancer [AJCC] stage, histological type, SUVmax, and MTV) were analyzed to identify their correlation with two-year survival. To further evaluate and compare the predictive value of PET parameters, MTV, and SUVmax, time-dependent receiver-operating characteristic curve (ROC) analysis was used. Results: In the univariate analysis, AJCC stage, histological type, MTV, and SUVmax of primary tumor were significant predictors of survival. On multivariate analysis, independent prognostic factors associated with decreased two-year survival were AJCC stage (hazard ratio [HR] 2.236, P 0.003), histological type (HR 2.038, P = 0. 004), and MTV (HR 1.016, P 0.001). SUVmax was not a significant factor (HR 0.96, P = 0.490). On time-dependent ROC analysis, MTV showed good predictive performance for two-year survival consistently better than SUVmax. Conclusion: MTV, a volumetric parameter of 18F-FDG PET, is an important independent prognostic factor for survival and a better predictor of survival than SUVmax for the primary tumor in patients with advanced NSCLC

    2006-01-01

    Esophageal achalasia is an infrequent motility disorder characterized by a progressive stasis and dilation of the oesophagus; with subsequent risk of aspiration,weight loss, and malnutrition. Although the treatment of achalasia has been traditionally based on a surgical approach, especially with the introduction of laparoscopic techniques, there is still some space for a medical approach. The present article reviews the non-surgical therapeutic options for achalasia.

  2. Non-surgical management of hepatocellular carcinoma

    Most of patients with hepatocellular carcinoma (HCC) cannot benefit from surgical therapies. Among non-surgical options, only radiofrequency can challenge surgery for small size tumours. Conformal radiotherapy is likely highly efficient on solitary tumours, but controlled studies are warranted to conclude. Other options are purely palliative. Trans-arterial hepatic chemo-embolization is the goal-standard for multifocal hepatocellular carcinoma and Sorafenib for hepatocellular carcinoma with portal vein invasion, leading to modest but significant benefit on survival rates. Yttrium-90 radio-embolization is under evaluation through controlled studies, and could be of major interest for multifocal hepatocellular carcinoma with or without portal venous invasion. (authors)

  3. Non-surgical interventions for convergence insufficiency

    Scheiman, Mitchell; Gwiazda, Jane; Li, Tianjing

    2014-01-01

    Background Convergence insufficiency is a common eye muscle co-ordination problem in which the eyes have a strong tendency to drift outward (exophoria) when reading or doing close work. Symptoms may include eye strain, headaches, double vision, print moving on the page, frequent loss of place when reading, inability to concentrate, and short attention span. Objectives To systematically assess and synthesize evidence from randomized controlled trials (RCTs) on the effectiveness of non-surgical interventions for convergence insufficiency. Search strategy We searched The Cochrane Library, MEDLINE, EMBASE, Science Citation Index, the metaRegister of Controlled Trials (mRCT) (www.controlled-trials.com) and ClinicalTrials.gov (www.clinicaltrials.gov) on 7 October 2010. We manually searched reference lists and optometric journals. Selection criteria We included RCTs examining any form of non-surgical intervention against placebo, no treatment, sham treatment, or each other. Data collection and analysis Two authors independently assessed eligibility, risk of bias, and extracted data. We performed meta-analyses when appropriate. Main results We included six trials (three in children, three in adults) with a total of 475 participants. We graded four trials at low risk of bias. Evidence from one trial (graded at low risk of bias) suggests that base-in prism reading glasses was no more effective than placebo reading glasses in improving clinical signs or symptoms in children. Evidence from one trial (graded at high risk of bias) suggests that base-in prism glasses using a progressive addition lens design was more effective than progressive addition lens alone in decreasing symptoms in adults. At three weeks of therapy, the mean difference in Convergence Insufficiency Symptoms Survey (CISS) score was −10.24 points (95% confidence interval (CI) −15.45 to −5.03). Evidence from two trials (graded at low risk of bias) suggests that outpatient (or office-based as used in the

    2007-10-01

    Venous thromboembolism (VTE) is known as a common complication in surgical and non-surgical patients. We hypothesized that according to the underlying risk factors and the acute illness, the prevalence ofVTE in non-surgical patients admitted to hospital is widely underestimated. For three months each patient admitted to the department of internal medicine with an acute illness, but without known deep venous thrombosis (DVT) was investigated by ultrasound compression sonography. Patients' history, risk factors and extent of immobilisation were documented. In patients with newly detected DVT D-dimer and fibrinogen were measured as well as computer tomography scans performed. Follow-up investigations of the DVT population were performed at four weeks and three months. Six hundred seventeen patients (49.3% men) were included. In 16 patients (men = 7) a previously unknown thrombosis (2.6%) was detected, mainly in patients with acute cardio-pulmonary disease (56%) and the elderly (mean age 75.6 years). Eight patients had femoro-popliteal (50.0%), four a femoral (25.0%), and four a popliteal vein thrombosis (25.0%). Five had pulmonary embolism (31.3%). In patients with DVT D-dimer was 875 +/- 1,228 mg/l, fibrinogen 568 +/- 215 mg/dl and C-reactive-protein 58.54 +/- 73.65 mg/dl. One patient died from sepsis during hospitalisation, one died from sudden cardiac death at home. None of the other 14 surviving patients relapsed. The study shows a 2.6% risk for DVT in outpatients with acute illness admitted to the department of internal medicine. These data demonstrate the high risk of DVT is in non-surgical patients. Early prophylaxis has to be considered in internal medicine patients especially in the elderly. PMID:17938799

  6. Non-surgical management of early breast cancer in the United Kingdom: the role and practice of radiotherapy. Clinical Audit Sub-committee of the Faculty of Clinical Oncology, Royal College of Radiologists, and the Joint Council for Clinical Oncology.

    Price, P; Yarnold, J R

    1995-01-01

    This paper reports on the delivery of radiotherapy to the primary site and lymphatic pathways in the management of early stage breast cancer. Radiotherapists were clear that their aim of locoregional radiotherapy was to reduce local recurrence. However, variation in policies for delivery were seen: 80% of radiotherapists did not always give radiotherapy routinely following wide local excision as part of breast conserving management; instead they withheld it selectively for a number of reasons. Only 66% routinely used breast boosts. There was a range of indications for giving radiotherapy to the lymphatic pathways; there was also variation in the management of incompletely or marginally excised primary tumours. Most sources of variation in the practice of radiotherapy in the management of women with early stage breast cancer appeared to arise from scientific uncertainty. However, organizational issues influenced many decisions. These scientific uncertainties and organizational issues are best addressed in the context of multidisciplinary breast clinics. PMID:8845315

  7. Non-surgical and non-chemical attempts to treat echinococcosis: do they work?

    Tamarozzi Francesca

    2014-01-01

    Full Text Available Cystic echinococcosis (CE and alveolar echinococcosis (AE are chronic, complex and neglected diseases. Their treatment depends on a number of factors related to the lesion, setting and patient. We performed a literature review of curative or palliative non-surgical, non-chemical interventions in CE and AE. In CE, some of these techniques, like radiofrequency thermal ablation (RFA, were shelved after initial attempts, while others, such as High-Intensity Focused Ultrasound, appear promising but are still in a pre-clinical phase. In AE, RFA has never been tested, however, radiotherapy or heavy-ion therapies have been attempted in experimental models. Still, application to humans is questionable. In CE, although prospective clinical studies are still lacking, therapeutic, non-surgical drainage techniques, such as PAIR (puncture, aspiration, injection, re-aspiration and its derivatives, are now considered a useful option in selected cases. Finally, palliative, non-surgical drainage techniques such as US- or CT-guided percutaneous biliary drainage, centro-parasitic abscesses drainage, or vascular stenting were performed successfully. Recently, endoscopic retrograde cholangiopancreatography (ERCP-associated techniques have become increasingly used to manage biliary fistulas in CE and biliary obstructions in AE. Development of pre-clinical animal models would allow testing for AE techniques developed for other indications, e.g. cancer. Prospective trials are required to determine the best use of PAIR, and associated procedures, and the indications and techniques of palliative drainage.

  8. Review of acute cancer beds.

    Evans, D S

    2012-01-01

    A review of admissions to cancer services at University Hospital Galway (UHG) was undertaken to assess the appropriateness of hospital usage. All cancer specialty patients admitted from 26-28 May 2009 were reviewed (n = 82). Chi square tests, Exact tests, and One-way ANOVA were utilised to analyse key issues emerging from the data. Fifty (61%) were classified as emergencies. Twenty three (67%) occupied a designated cancer bed with 24 (30%) in outlying non-oncology wards. The mean length of stay was 29.3 days. Possible alternatives to admission were identified for 15 (19%) patients. There was no evidence of discharge planning for 50 (60%) admissions. There is considerable potential to make more appropriate utilisation of UHG for cancer patients, particularly in terms of reducing bed days and length of stay and the proportion of emergency cancer admissions, and further developing integrated systems of discharge planning.

  9. Cancer, acute stress disorder, and repressive coping

    Pedersen, Anette Fischer; Zachariae, Robert

    2010-01-01

    The purpose of this study was to investigate the association between repressive coping style and Acute Stress Disorder (ASD) in a sample of cancer patients. A total of 112 cancer patients recently diagnosed with cancer participated in the study. ASD was assessed by the Stanford Acute Stress...... Reaction Questionnaire, and repressive coping was assessed by a combination of scores from the Marlowe-Crowne Social Desirability Scale, and the Bendig version of the Taylor Manifest Anxiety Scale. Significantly fewer patients classified as "repressors" were diagnosed with ASD compared to patients...... classified as "non-repressors". However, further investigations revealed that the lower incidence of ASD in repressors apparently was caused by a low score on anxiety and not by an interaction effect between anxiety and defensiveness. Future studies have to investigate whether different psychological...

  10. Non-surgical management of early breast cancer in the United Kingdom: follow-up. Clinical Audit Sub-committee of the Faculty of Clinical Oncology, Royal College of Radiologists, and the Joint Council for Clinical Oncology.

    Maher, E J

    1995-01-01

    Follow-up of operable breast cancer patients takes up a significant proportion of British oncologists' time, with 90% seeing 5-50 patients each week. Procedures vary greatly, but, in patients treated by surgery and radiotherapy, care is usually shared, with alternating visits to see each team. Currently, the general practitioner has sole responsibility for follow-up in less than 3% of patients. They tend to be followed up in general, rather than specialist, clinics. There is almost universal agreement that routine blood tests, radiographs and scans are not indicated as part of routine follow-up, but the role of mammography in evaluating an irradiated breast remains a source of debate. Just over a half of the oncologists surveyed order baseline mammography of both treated and contralateral breasts, usually between 6 and 12 months after local excision and radiotherapy, with further follow-up 1-3-yearly thereafter. Ten per cent of the participating oncologists never suggest follow-up mammography. Patients tend to be followed in oncology clinics at 3-4-monthly intervals for the first 2 years, 6-monthly in the third and fourth years and, thereafter, yearly. Fifteen per cent of oncologists discharge patients at 5 years, with the discharge rate rising to 43% at 10 years; around one-third modify follow-up according to the age of the patient. The aims of follow-up were seen to include detection of curable disease, but other goals were perceived as equally important (e.g. detection of iatrogenic problems, audit, counselling, education and the provision of early palliation of incurable and metastatic disease. Breast cancer is no longer seen as an absolute contraindication to either pregnancy or the use of hormone replacement therapy (HRT); however, oncologists are uncertain about the appropriate use of HRT, either alone or with tamoxifen. This audit highlights a number of research areas: the identification of the appropriate site and skill-mix for follow-up of patients

    Penile cancer is a rare malignancy in our country. Phimosis, poor hygiene and smoking are major risk factors for penile cancer. Penile cancer in men have a strong correlation with human papillomavirus (HPV) infection. Penile cancer is rare in circumcised men, particularly if they are circumcised as newborns. Penile cancer is usually asymptomatic and physical examination is essential for diagnosis. We report a case of penile cancer whose first symptom was acute urinary retention (AUR) and revi...

  13. Acute leukaemia: making sense of a complex blood cancer.

    Meenaghan, Teresa

    2012-01-01

    Acute leukaemia represents a diverse group of blood cancers that affect both children and adults. Treatment schedules for these haematology cancers are often prolonged, with many associated side effects and complications. Nurses caring for patients with acute leukaemia require an anticipatory approach, where care is aimed at minimizing the side effects of treatment and being constantly vigilant for any impending adverse effects. Moreover, patients require support for the psychosocial issues that can arise for patients during their illness. This article provides an overview of acute lymphoblastic leukaemia and acute myeloid leukaemia. Nursing considerations in the care of patients being treated for acute leukaemia are also explored.

  14. Orthotics Compared to Conventional Therapy and Other Non-Surgical Treatments for Plantar Fasciitis

    Lewis, Rebecca D.; Wright, Paul; McCarthy, Laine H.

    2016-01-01

    Clinical Question In adults with acute plantar fasciitis whose symptoms have not been relieved with the conventional regimen of NSAIDS, stretching and lifestyle modification, do the addition of orthotics (prefabricated or custom fitted) reduce pain and improve function compared with other non-surgical treatments (manipulative chiropractic, physical therapy and/or heel steroid injections)? Answer Yes. Studies have shown that orthotics, both prefabricated and custom fitted, reduce pain and improve function in adults with acute plantar fasciitis with few risks or side effects. Used alone or in addition to conventional therapy (NSAIDs, stretching, lifestyle modification), orthotics are effective and well tolerated by patients for short-term pain relief and improved function. Prefabricated orthotics are less costly and provide similar relief to more expensive custom orthotics. Level of Evidence of the Answer A Search Terms Plantar fasciitis, heel pain, treatment, orthotics, Limits Adult, human, English, Review, Randomized-Control Trials, Systematic Reviews, adults age 18 or more, publication dates 2004 to present. Date Search was Conducted January 16, 2014; updated January 20, 2015 Inclusion Criteria Recent published systematic reviews, randomized controlled, meta-analyses; adults with confirmed acute or recent diagnosis of plantar fasciitis. Exclusion Criteria Studies older than 10 years, children, adolescents less than 18 years of age, chronic or recalcitrant plantar fasciitis. PMID:26855444

  15. Cancer risk of patients discharged with acute myocardial infarct

    Dreyer, L; Olsen, J H

    1998-01-01

    We studied whether common shared environmental or behavioral risk factors, other than tobacco smoking, underlie both atherosclerotic diseases and cancer. We identified a group of 96,891 one-year survivors of acute myocardial infarct through the Danish Hospital Discharge Register between 1977 and...... acute myocardial infarct patients were similar to those of the general population, as were the rates for hormone-related cancers, including endometrial and postmenopausal breast cancers. We found a moderate increase in the risk for tobacco-related cancers, which was strongest for patients with early...... onset of acute myocardial infarct and for female patients. Overall, there do not seem to be major shared environmental or behavioral risk factors for acute myocardial infarct and cancers, except for smoking, and there seems to be no common inherited susceptibility to the development of these diseases....

  18. Acute limb ischemia in cancer patients: should we surgically intervene?

    Tsang, Julian S

    2012-02-01

    BACKGROUND: Cancer patients have an increased risk of venous thromboembolic events. Certain chemotherapeutic agents have also been associated with the development of thrombosis. Reported cases of acute arterial ischemic episodes in cancer patients are rare. METHODS: Patients who underwent surgery for acute limb ischemia associated with malignancy in a university teaching hospital over a 10-year period were identified. Patient demographics, cancer type, chemotherapy use, site of thromboembolism, treatment and outcome were recorded. RESULTS: Four hundred nineteen patients underwent surgical intervention for acute arterial ischemia, 16 of these patients (3.8%) had associated cancer. Commonest cancer sites were the urogenital tract (n = 5) and the lungs (n = 5). Eight patients (50%) had been recently diagnosed with cancer, and four (25%) of these cancers were incidental findings after presentation with acute limb ischemia. Four patients (25%) developed acute ischemia during chemotherapy. The superficial femoral artery was the most frequent site of occlusion (50%), followed by the brachial (18%) and popliteal (12%) arteries. All patients underwent thromboembolectomy, but two (12%) patients subsequently required a bypass procedure. Six patients (37%) had limb loss, and in-patient mortality was 12%. Histology revealed that all occlusions were due to thromboembolism, with no tumor cells identified. At follow-up, 44% of patients were found to be alive after 1 year. CONCLUSION: Cancer and chemotherapy can predispose patients to acute arterial ischemia. Unlike other reports that view this finding as a preterminal event most appropriately treated by palliative measures, in this series, early diagnosis and surgical intervention enabled limb salvage and patient survival.

    2016-01-01

    Background Patients with hallux valgus (HV) frequently present to podiatrists for non-surgical management, with a wide range of concerns including pain, footwear difficulty and quality of life impacts. There is little research evidence guiding podiatrists’ clinical decisions surrounding non-surgical management of HV. Thus practitioners rely largely upon clinical experience and expert opinion. This survey was conducted to determine whether a consensus exists among Australian podiatrists regard...

    2011-11-01

    Full Text Available Context Acute recurrent pancreatitis still poses diagnostic difficulties. The coexistence or moreover the causative relationship of carcinoma of the ampulla of Vater and acute recurrent pancreatitis is fairly rare. Case report We present a case of carcinoma of the ampulla of Vater that presented with acute recurrent necrotizing pancreatitis complicated with pseudocysts. A diagnosis of malignancy in the ampulla was only made after several ERCP attempts due to residual inflammation at the periampullary area. Conclusion Malignancy at the ampulla of Vater causing recurrent episodes of pancreatitis represents a realistic risk and attempts to diagnose the underlying cause should always take into account the possibility of cancer.

  4. Surgical and non-surgical therapy: Complement or paradox?

    The evolution of knowledge concerning tumor biology and the development of therapeutic tools against cancer have radically changed the approach to the oncologic patient. Up to yesterday it was pertinent to a single specialist; nowadays it has turned into a multidisciplinary one. As regards the role of surgery in this context, the Authors describe some situations in which a synergism between the latter, radiotherapy and chemotherapy is likely to be accomplished; the consequent advantages in terms of therapeutic efficacy are discussed

  5. Barriers and Facilitators Associated with Non-Surgical Treatment Use for Osteoarthritis Patients in Orthopaedic Practice.

    Stefanie N Hofstede

    Full Text Available International evidence-based guidelines for the management of patients with hip and knee osteoarthritis (OA recommend to start with (a combination of non-surgical treatments, and using surgical intervention only if a patient does not respond sufficiently to non-surgical treatment options. Despite these recommendations, there are strong indications that non-surgical treatments are not optimally used in orthopaedic practice. To improve the adoption of non-surgical treatments, more insight is needed into barriers and facilitators of these treatments. Therefore, this study assessed which barriers and facilitators are associated with the use and prescription of different non-surgical treatments before hip and knee OA in orthopaedic practice among patients and orthopaedic surgeons in the Netherlands.We performed two internet-based surveys among 172 orthopaedic surgeons and 174 OA patients. Univariate association and multivariable regression techniques are used to identify barriers and facilitators associated with the use of non-surgical treatments.Most barriers and facilitators among patients were associated with the use of physical therapy, lifestyle advice and dietary therapy. Among orthopaedic surgeons, most were associated with prescription of acetaminophen, dietary therapy and physical therapy. Examples of barriers and facilitators among patients included "People in my environment had positive experiences with a surgery" (facilitator for education about OA, and "Advice of people in my environment to keep on moving" (facilitator for lifestyle and dietary advice. For orthopaedic surgeons, examples were "Lack of knowledge about guideline" (barrier for lifestyle advice, "Agreements/ deliberations with primary care" and "Easy communication with a dietician" (facilitators for dietary therapy. Also the belief in the efficacy of these treatments was associated with increased prescription.Strategies to improve non-surgical treatment use in orthopaedic

  6. Effect of acute exercise on prostate cancer cell growth.

    Helene Rundqvist

    Full Text Available Physical activity is associated with reduced risk of several cancers, including aggressive prostate cancer. The mechanisms mediating the effects are not yet understood; among the candidates are modifications of endogenous hormone levels. Long-term exercise is known to reduce serum levels of growth stimulating hormones. In contrast, the endocrine effects of acute endurance exercise include increased levels of mitogenic factors such as GH and IGF-1. It can be speculated that the elevation of serum growth factors may be detrimental to prostate cancer progression into malignancy. The incentive of the current study is to evaluate the effect of acute exercise serum on prostate cancer cell growth. We designed an exercise intervention where 10 male individuals performed 60 minutes of bicycle exercise at increasing intensity. Serum samples were obtained before (rest serum and after completed exercise (exercise serum. The established prostate cancer cell line LNCaP was exposed to exercise or rest serum. Exercise serum from 9 out of 10 individuals had a growth inhibitory effect on LNCaP cells. Incubation with pooled exercise serum resulted in a 31% inhibition of LNCaP growth and pre-incubation before subcutaneous injection into SCID mice caused a delay in tumor formation. Serum analyses indicated two possible candidates for the effect; increased levels of IGFBP-1 and reduced levels of EGF. In conclusion, despite the fear of possible detrimental effects of acute exercise serum on tumor cell growth, we show that even the short-term effects seem to add to the overall beneficial influence of exercise on neoplasia.

  7. MR imaging of idiopathic trigeminal neuralgia. Correlation with non-surgical therapy

    Magnetic resonance (MR) findings in patients with idiopathic trigeminal neuralgia were evaluated and correlated with the effectiveness of non-surgical treatments. Thirty-four patients with idiopathic trigeminal neuralgia (ITN) were examined using T1-and T2-weighted spin-echo (SE) pulse sequence techniques to evaluate their trigeminal root-entry zones and the vessels contacted prior to non-surgical treatment (retrogasserian glycerol injection, peripheral nerve block, or only oral analgesics). Vascular contact at the proximal portion of the preganglionic segment (PGS) of the trigeminal nerve and deformity of the PGS on the affected side were observed in 97% and 47% of the patients, respectively. Non-surgical treatments were curative in 12 (67%) but failed in two (11%) of the 18 patients without deformed PGS. However, among 16 patients with deformed PGS, they were curative in only six (37.5%) and failed in four (25%). Results of this study suggest that MR imaging could be useful in the clinical assessment of trigeminal neuralgia prior to instituting non-surgical treatment. (author)

  10. Acute kidney injury in critically ill cancer patients: an update.

    Lameire, Norbert; Vanholder, Raymond; Van Biesen, Wim; Benoit, Dominique

    2016-01-01

    Patients with cancer represent a growing group among actual ICU admissions (up to 20 %). Due to their increased susceptibility to infectious and noninfectious complications related to the underlying cancer itself or its treatment, these patients frequently develop acute kidney injury (AKI). A wide variety of definitions for AKI are still used in the cancer literature, despite existing guidelines on definitions and staging of AKI. Alternative diagnostic investigations such as Cystatin C and urinary biomarkers are discussed briefly. This review summarizes the literature between 2010 and 2015 on epidemiology and prognosis of AKI in this population. Overall, the causes of AKI in the setting of malignancy are similar to those in other clinical settings, including preexisting chronic kidney disease. In addition, nephrotoxicity induced by the anticancer treatments including the more recently introduced targeted therapies is increasingly observed. However, data are sometimes difficult to interpret because they are often presented from the oncological rather than from the nephrological point of view. Because the development of the acute tumor lysis syndrome is one of the major causes of AKI in patients with a high tumor burden or a high cell turnover, the diagnosis, risk factors, and preventive measures of the syndrome will be discussed. Finally, we will briefly discuss renal replacement therapy modalities and the emergence of chronic kidney disease in the growing subgroup of critically ill post-AKI survivors. PMID:27480256

  11. Radiation therapy in prostate cancer: evaluation of acute toxicity

    Goals: The present work documents the increasing demand of curative intent radiation therapy (CIRT) for localized prostate cancer and assesses acute reactions caused by ionizing radiation to intrapelvic organs. Patients and methods: From January 1995 to December 2001, 166 patients with prostatic cancer received radiation therapy, 70% of them (n=116) with curative intent. Treatment was completed as planned in 108 patients: 55 with pelvic irradiation and prostatic boost (PRT), 42 with three-dimensional conformal radiotherapy (3DCRT), 10 with a permanent 125 I implant (IPI) and 1 with combined radiotherapy. Patients were classified as at high- or low-risk according to tumor volume, Gleason score, regional lymph node status and pretreatment specific prostatic antigen level. High-risk patients were assigned to PRT and low-risk patients to local treatment only (either 3DCRT or IPI). Mean doses were 46 Gy for pelvis and 73 Gy for prostate with PRT; 75 Gy with 3DCRT and 127 Gy with IPI and combined radiation therapy. Acute rectal toxicity (ART) and acute urinary toxicity (AUT) were assessed according to the RTOG scale. Statistical analysis was performed with Fischer's exact test. Results: The proportion of patients receiving CIRT increased from 46% (n=28) in 1995-1998 to 84% (n=88) in 1999-2001; p < 0.0001. No patient developed ART or AUT beyond degree 2. ART was lower with 3DCRT (71% degree 0 or 1) than with PRT (45% degree 0 or 1); p= 0.0134. No significant difference was found in AUT. Conclusions: In recent years the demand for CIRT has almost doubled, with a concomitant decrease in palliative radiotherapy. In high-risk patients, pelvic irradiation increased mild and moderate ART, without compromising their life quality. None of the techniques employed was associated with severe acute toxicity.

    Hüfner, Tobias; Wohifarth, Kai; Fink, Matthias; Thermann, H; Rollnik, Jens D

    2002-07-01

    After surgical therapy of Achilles tendon rupture, neuromuscular changes may persist, even one year after surgery. We were interested whether these changes are also evident following a non-surgical functional therapy (Variostabil therapy boot/Adidas). Twenty-one patients with complete Achilles tendon rupture were enrolled in the study (mean age 38.5 years, range 24 to 60; 18 men, three women) and followed-up clinically and with surface EMG of the gastrocnemius muscles after four, eight, 12 weeks, and one year after rupture. EMG differences between the affected and non-affected side could only be observed at baseline and after four weeks following Achilles tendon rupture. The results from our study show that EMG changes are not found following non-surgical functional therapy. PMID:12146771

  14. Non-surgical interventions for adolescents with idiopathic scoliosis: an overview of systematic reviews.

    Maciej Płaszewski

    Full Text Available BACKGROUND: Non-surgical interventions for adolescents with idiopathic scoliosis remain highly controversial. Despite the publication of numerous reviews no explicit methodological evaluation of papers labeled as, or having a layout of, a systematic review, addressing this subject matter, is available. OBJECTIVES: Analysis and comparison of the content, methodology, and evidence-base from systematic reviews regarding non-surgical interventions for adolescents with idiopathic scoliosis. DESIGN: Systematic overview of systematic reviews. METHODS: Articles meeting the minimal criteria for a systematic review, regarding any non-surgical intervention for adolescent idiopathic scoliosis, with any outcomes measured, were included. Multiple general and systematic review specific databases, guideline registries, reference lists and websites of institutions were searched. The AMSTAR tool was used to critically appraise the methodology, and the Oxford Centre for Evidence Based Medicine and the Joanna Briggs Institute's hierarchies were applied to analyze the levels of evidence from included reviews. RESULTS: From 469 citations, twenty one papers were included for analysis. Five reviews assessed the effectiveness of scoliosis-specific exercise treatments, four assessed manual therapies, five evaluated bracing, four assessed different combinations of interventions, and one evaluated usual physical activity. Two reviews addressed the adverse effects of bracing. Two papers were high quality Cochrane reviews, Three were of moderate, and the remaining sixteen were of low or very low methodological quality. The level of evidence of these reviews ranged from 1 or 1+ to 4, and in some reviews, due to their low methodological quality and/or poor reporting, this could not be established. CONCLUSIONS: Higher quality reviews indicate that generally there is insufficient evidence to make a judgment on whether non-surgical interventions in adolescent idiopathic scoliosis

    Full Text Available Pulmonary tumor thrombotic microangiopathy (PTTM is a rare condition causing pulmonary artery hypertension and acute right heart failure in patients with cancer. However, chest computer tomography shows negative finding of pulmonary thromboembolism. Serum D-dimer level may be elevated. Echocardiography reveals a dilated right ventricle and feature of pulmonary artery hypertension. Establishing this diagnosis can be very difficult, and most cases are diagnosed during autopsy, although a history of cancer may be a predictor. PTTM should be considered in all patients with apparent pulmonary artery hypertension and elevated D-dimer level, particularly when the patient is known to have an underlying malignancy, especially adenocarcinoma and most of all, the clinical manifestation is very rapidly progressive.

    Objective To observe the therapeutic effect of non-surgical treatment on diabetic Chinese with chronic periodontitis. Methods Moderate to advanced chronic periodontitis (CP) was studied in 36 diabetes mellitus (DM) patients classified as 20 with high and fiuctuating blood glucose level (DM-H) and 16 with relatively low and stable blood glucose level (DM-L). 28 non-DM CP patients acted as controls (Non-DM). Plaque index (PH), gingival index (Gl), bleeding on probing (BOP), probing depth (PD) and clinical attachment loss (AL)of all patients were recorded at 6 sites on each tooth at the baseline and 1,3 and 6 months after oral hygiene instruction ( OHI) , scaling and root planing. Results It was found that the short-term effect of non-surgical periodontal procedure had resulted in significant resolution of gingival inflammation and pronounced reduction in pocket depth and gain of attachment loss in both DM and Non-DM CP patients. Conclusion The pilot study suggested that non-surgical periodontal treatment allowed for favorable treatment responses in a group of Chinese diabetic subjects with chronic periodontitis and that their various profiles of blood glucose did not influence the short-term healing response to OHI, scaling and root planning.

    2010-12-01

    Full Text Available Chronic kidney disease (CKD is a debilitating systemic condition. Our working hypothesis is that CKD predialysis patients with periodontitis would respond poorly to periodontal treatment owing to immunologic compromise. Twenty-one predialysis patients (group 1 and 19 individuals without clinical evidence of kidney disease (group 2 with chronic periodontitis were subjected to non-surgical periodontal treatment with no antibiotics. Clinical periodontal and systemic parameters were evaluated at baseline and 3 months after treatment. Both groups showed significant and similar post-treatment improvements in all periodontal parameters examined. Most interestingly, periodontal treatment had a statistically significant positive effect on the glomerular filtration rate of each individual (group 1, p = 0.04; group 2, p = 0.002. Our results indicate that chronic periodontitis in predialysis kidney disease patients improved similarly in patients with chronic periodontitis and no history of CKD after receiving non-surgical periodontal therapy. This study demonstrates that CKD predialysis patients show a good response to non-surgical periodontal treatment.

    Most of patients with hepatocellular carcinoma (HCC) cannot benefit from surgical therapies. Among non-surgical options, only radiofrequency can challenge surgery for small size tumours. Conformal radiotherapy is likely highly efficient on solitary tumours, but controlled studies are warranted to conclude. Other options are purely palliative. Trans-arterial hepatic chemo-embolization is the goal-standard for multifocal hepatocellular carcinoma and Sorafenib for hepatocellular carcinoma with portal vein invasion, leading to modest but significant benefit on survival rates. Yttrium-90 radio-embolization is under evaluation through controlled studies, and could be of major interest for multifocal hepatocellular carcinoma with or without portal venous invasion. (authors)

    Full Text Available INTRODUCTION: Rupture of the pectoralis major muscle appears to be increasing in athletes. However, the optimal treatment strategy has not yet been established. OBJECTIVES: To compare the isokinetic shoulder performance after surgical treatment to that after non-surgical treatment for pectoralis major muscle rupture. METHODS: We assessed 33 pectoralis major muscle ruptures (18 treated non-surgically and 15 treated surgically. Horizontal abduction and adduction as well as external and internal rotation at 60 and 120 degrees/s were tested in both upper limbs. Peak torque, total work, contralateral deficiency, and the peak torque agonist-to-antagonist ratio were measured. RESULTS: Contralateral muscular deficiency did not differ between the surgical and non-surgical treatment modalities. However, the surgical group presented twice the number of athletes with clinically acceptable contralateral deficiency (<20% for internal rotators compared to the non-surgical group. The peak torque ratio between the external and internal rotator muscles revealed a similar deficit of the external rotation in both groups and on both sides (surgical, 61.60% and 57.80% and non-surgical, 62.06% and 54.06%, for the dominant and non-dominant sides, respectively. The peak torque ratio revealed that the horizontal adduction muscles on the injured side showed similar weakness in both groups (surgical, 86.27%; non-surgical, 98.61%. CONCLUSIONS: This study included the largest single series of athletes reported to date for this type of injury. A comparative analysis of muscular strength and balance showed no differences between the treatment modalities for pectoralis major muscle rupture. However, the number of significant clinical deficiencies was lower in the surgical group than in the non-surgical group, and both treatment modalities require greater attention to the rehabilitation process, especially for the recovery of muscle strength and balance.

  6. The methodological quality of systematic reviews comparing temporomandibular joint disorder surgical and non-surgical treatment

    Vasconcelos Belmiro CE

    2008-09-01

    Full Text Available Abstract Background Temporomandibular joint disorders (TMJD are multifactor, complex clinical problems affecting approximately 60–70% of the general population, with considerable controversy about the most effective treatment. For example, reports claim success rates of 70% and 83% for non-surgical and surgical treatment, whereas other reports claim success rates of 40% to 70% for self-improvement without treatment. Therefore, the purpose of this study was to (1 identify systematic reviews comparing temporomandibular joint disorder surgical and non-surgical treatment, (2 evaluate their methodological quality, and (3 evaluate the evidence grade within the systematic reviews. Methods A search strategy was developed and implemented for MEDLINE, Cochrane Library, LILACS, and Brazilian Dentistry Bibliography databases. Inclusion criteria were: systematic reviews (± meta-analysis comparing surgical and non-surgical TMJD treatment, published in English, Spanish, Portuguese, Italian, or German between the years 1966 and 2007(up to July. Exclusion criteria were: in vitro or animal studies; narrative reviews or editorials or editorial letters; and articles published in other languages. Two investigators independently selected and evaluated systematic reviews. Three different instruments (AMSTAR, OQAQ and CASP were used to evaluate methodological quality, and the results averaged. The GRADE instrument was used to evaluate the evidence grade within the reviews. Results The search strategy identified 211 reports; of which 2 were systematic reviews meeting inclusion criteria. The first review met 23.5 ± 6.0% and the second met 77.5 ± 12.8% of the methodological quality criteria (mean ± sd. In these systematic reviews between 9 and 15% of the trials were graded as high quality, and 2 and 8% of the total number of patients were involved in these studies. Conclusion The results indicate that in spite of the widespread impact of TMJD, and the multitude of

  9. Clinical effect of ibuprofen as an adjunct to non-surgical periodontal disease treatment

    Đurić Milanko Đ.

    2002-01-01

    Full Text Available Twenty five patients with progresive periodontal disease entered this study in order to examine clinical effects of a non-steroidal anti-inflammatory drug - ibuprofen, used as an adjunct to non-surgical periodontal treatment. After scaling and root planning, patients were randomly assigned to either receive orally 200 mg of ibuprofen per day for one month (group A, or not receive the drug (group B. The obtained results show that the mechanical periodontal treatment brought to resolution the gingival inflammation with both group of patients. Although the mean values of the used indices were lower in group A than in group B, those differences were neither statistically nor clinically significant. We may conclude that systemic ibuprofen had no significant effect on plaque, gingival or bleeding index scores.

  10. Rescue of a periodontally compromised tooth by non-surgical treatment: a case report

    2016-01-01

    Purpose This article describes a case of the successful non-surgical management of a periodontally compromised maxillary premolar. Methods A combination therapy, including root planing, occlusal adjustment, and tooth splinting, was applied. Clinical and radiographic examinations were performed during the 16-month follow-up period. Results All periodontal parameters were improved. There were dramatic decreases (3–6 mm) in the probing pocket depth, tooth mobility, and marginal bone loss. Interestingly, gradual resolution of the periapical radiolucency and alveolar bone regeneration were observed in the radiographs, and the periodontal condition was maintained during the follow-up period. Conclusions Within the limits of this study, these results demonstrate the importance of natural tooth preservation through proper periodontal treatment and occlusal adjustment of the periodontally compromised tooth, which is typically targeted for tooth extraction and dental implantation.

  13. Involvement of Toll-like receptors in acute radiation syndrome and radiation therapy for cancer

    Toll-like receptors (TLR) are one of pattern recognition receptors that are indispensable for antibacterial and antiviral immunity. After TLRs sense pathogen-derived components, they activate intracellular signaling pathways, which results in the induction of proinflammatory cytokines. Although it is well known that radiation therapy is one of effective cancer therapies, radiation affects immune system. Recent evidences show the involvement of TLR in acute radiation syndrome and radiation therapy for cancer. I summarize to date knowledge on the involvement of Toll-like receptors in acute radiation syndromes and radiation therapy for cancer, and discuss the effects of ionizing radiation on TLR of innate immune cells.

    Neville-Webbe, H L; Carser, J E; Wong, H; Andrews, J; Poulter, T; Smith, R; Marshall, E

    2013-12-01

    The 2008 National Confidential Enquiry into Patient Outcomes and Death highlighted an urgent need to improve the quality, safety and efficiency of care for cancer patients following emergency presentation to acute general hospitals. A network-wide acute oncology service (AOS) was therefore commissioned and implemented on the basis of recommendations from the National Chemotherapy Advisory Group (NCAG). Through a continuous programme of raising awareness regarding both the role of the AOS and the necessity of early patient referral to acute oncology teams, we have been able to establish an AOS across all acute trusts in our cancer network. The network-wide AOS has improved communication across clinical teams, enabled rapid review of over 3,000 patients by oncology staff, reduced hospital stay, increased understanding of oncology emergencies and their treatment, and enhanced pathways for rapid diagnosis and appropriate referrals for patients presenting with malignancy of undefined origin (MUO). These achievements have been made by developing a network protocol book for managing common oncology emergencies, by introducing local pathways for managing MUO and by collaborating with palliative care teams to introduce local acute oncology (AO) multi-disciplinary team (MDT) meetings.

  16. Image processing and quantitative assessment in computer tomography for non-surgical treatment of brain tumours

    Using the EMI computer tomographic (CT) system, EMI-1010, a series of new programmes were developed for the digital analysis of the CT images in order to make a more objective and quantitative assessment possible of two non-surgical methods of treatment of brain tumours such as irradiation and chemotherapy. Amongst the various therapeutic effects demonstrable from the CT data, a reduction of the mass effect was found to lower the average CT number, with a dilatation of the cisterns and ventricles. In contrast, an improvement in the amount of perifocal oedema increased the average CT number of the region, however the changes in CT number of the tumour itself may be variable. The separate evaluation of these factors, therefore, gives more information about the results of the treatment than a simple analysis of the histogram of the region. Circumscribed tumours are fairly well evaluated with our programme for the statistical analysis of the volume and the CT weight of tumours and the degree of contrast enhancement using histograms and subtraction scans. For the digital analysis of the ventricular system, the subarachnoid space, perifocal oedema, and irregularly shaped infiltrating tumours, our programmes for the character-image print-out and edge correction for the partial-volume effect of skull and air are much more useful than the CRT display for data extraction and geographic-pattern recognition.

  20. Acute Morbidity of Proton Therapy for Prostate Cancer: The Hyogo Ion Beam Medical Center Experience

    Purpose: To investigate the incidence and influencing factors of acute genitourinary (GU) and gastrointestinal morbidities in patients with prostate cancer treated with proton therapy. Methods and Materials: A total of 287 patients with histologically proven Stage cT1-T4N0M0 prostate cancer were treated with proton therapy between 2003 and 2004. Of these, 204 (71%) received neoadjuvant androgen suppression therapy. The patients were treated with 190-230-MeV protons using lateral-opposed techniques to a dose of 74 GyE. Dose-volume histogram analyses were performed. The incidence of acute morbidity was evaluated using the National Cancer Institute Common Toxicity Criteria, version 2.0. Clinical factors, including age, clinical target volume, initial prostate-specific antigen level, T stage, presence of diabetes mellitus, and the use of androgen suppression therapy, were investigated to determine whether those affected the incidence of acute GU morbidity. Results: None developed Grade 2 or higher acute gastrointestinal morbidity. In contrast, 111 (39%) and 4 (1%) patients experienced acute Grade 2 and Grade 3 GU morbidities, respectively. However, 87% of the patients were successfully relieved by the administration of a selective α-1 blocker. Multivariate analysis showed that a larger clinical target volume (p = 0.001) and the use of androgen suppression therapy (p = 0.017) were significant factors for the prediction of acute Grade 2-3 GU morbidity. Conclusion: In our experience with proton therapy, a low incidence of acute gastrointestinal morbidity was observed. In contrast, the incidence of acute GU morbidity was similar to that in other reports of photon radiotherapy. Additional follow-up is warranted to elucidate the long-term safety and efficacy of proton therapy for prostate cancer

    Objective Endoscopic gallbladder stenting (EGBS) is an alternative treatment option for high-risk surgical patients with acute cholecystitis. However, there are no reports focusing on EGBS in patients with concomitant unresectable cancer. The aim of this study was thus to evaluate EGBS in such patients. Methods Twenty-two consecutive patients with acute cholecystitis and unresectable cancer were enrolled between September 2010 and December 2014. Their median age was 74.5 years (range: 51-95). Thirteen patients were men and nine were women. The primary cancers of the patients were biliary tract cancer (9), pancreas cancer (9), lung cancer (2), gastric cancer (1), and colon cancer (1). The causes of cholecystitis were calculus cholecystitis (7), obstruction by malignant tumor (13), and obstruction by fully covered stent (2). Results EGBS was successfully performed in 17 patients (77.2%). The technical success rates for calculus cholecystitis, obstruction by malignant tumor, and obstruction by fully covered stent were 85.7% (6/7), 69.2% (9/13), and 100% (2/2), respectively. No complications were observed. Percutaneous transhepatic gallbladder drainage was conducted on two patients in whom EGBS had failed and then we performed EGBS by a rendezvous approach. Of the 19 patients in whom we finally deployed EGBS, the median follow-up period was 229 days (range: 14-880 days). A recurrence of acute cholecystitis occurred in three (15.7%) patients 14, 130, and 440 days after EGBS placement. The rates of recurrence of cholecystitis at one and two years were 10.5% and 18.7%, respectively. Conclusion Our study demonstrated that EGBS is a safe and effective method for acute cholecystitis in patients with concomitant unresectable cancer. PMID:27250045

  2. Hypoxyradiotherapy of uterine cervix cancer to decrease of acute side-effects and treatment complications

    The authors have reported on preliminary results of hypoxyradiotherapy in the course of external irradiation in patients with uterine cervix cancer from a view-point of the occurrence of acute reactions and treatment complications. A mixture of nitrogen and oxygen containing 8.0 to 8.5% of O2 was used to provoke acute hypoxia during irradiation. The applied dosis of external irradiation was simultaneously increased by 40%. On the basis of a randomized study with 120 patients, acute hypoxia was found to protect healthy tissues against post-radiation damage. When the dosis of 96 Gy in the paracervical space and that of 75 Gy in the pelvic wall were applied, acute side-effects decreases significantly if compared with a conventional radiotherapeutic procedure (p<0.01). Radiological preconditions for using acute hypoxia in radiotherapy are discussed. (orig.)

  3. Prognostic factors in non-surgically treated sciatica: A systematic review

    Ashworth Julie

    2011-09-01

    Full Text Available Abstract Background When present sciatica is considered an obstacle to recovery in low back pain patients, yet evidence is limited regarding prognostic factors for persistent disability in this patient group. The aim of this study is to describe and summarise the evidence regarding prognostic factors for sciatica in non-surgically treated cohorts. Understanding the prognostic factors in sciatica and their relative importance may allow the identification of patients with particular risk factors who might benefit from early or specific types of treatment in order to optimise outcome. Methods A systematic literature search was conducted using Medline, EMBASE and CINAHL electronic databases. Prospective cohort studies describing subjects with sciatica and measuring pain, disability or recovery outcomes were included. Studies of cohorts comprised entirely of surgically treated patients were excluded and mixed surgically and conservatively treated cohorts were included only if the results were analysed separately by treatment group or if the analysis was adjusted for treatment. Results Seven adequate or high quality eligible studies were identified. There were conflicting but mainly negative results regarding the influence of baseline pain severity, neurological deficit, nerve root tension signs, duration of symptoms and radiological findings on outcome. A number of factors including age, gender, smoking, previous history of sciatica and heaviness of work do not appear to influence outcome. In contrast to studies of low back pain and purely surgically treated sciatica cohorts, psychological factors were rarely investigated. Conclusions At present, the heterogeneity of the available studies makes it difficult to draw firm conclusions about sciatica prognosis, and highlights the need for further research for this group of patients.

    Wilson, M S

    1993-01-01

    A total of 46 bitches were inseminated directly into the uterus using non-surgical insemination procedures; the technique used in six bitches involved specially designed metal catheters and abdominal fixation of the cervix, whereas the remainder were inseminated by passing a flexible plastic catheter through the cervix using direct endoscopic visualization to facilitate the process. Twenty-seven bitches were inseminated with semen frozen at the clinic; the remainder were inseminated with imported semen. Insemination timing was based on endoscopic assessment of the vaginal mucosa, vaginal cytology and blood progesterone concentration determined using a rapid, qualitative enzyme-linked immunosorbent assay (ELISA) kit. Each bitch received between 50 x 10(6) and 200 x 10(6) total spermatozoa per insemination; post-thaw motility varied from 10 to 80%. Two inseminations were performed 48 h apart in the majority of bitches. An overall pregnancy rate of 80% (37/46) was obtained with a mean litter size of 5 +/- 3.14. Subsequent pregnancy rates were comparable for both techniques and both were considered to be effective methods of inseminating frozen semen. Considerably fewer spermatozoa were inseminated in many of these bitches than have previously been reported. In a series of seven bitches using the semen from one dog, each bitch received two inseminations of 30-35 x 10(6) live normal spermatozoa per insemination. A pregnancy rate of 85% (6/7) and a mean litter size of 7.8 was achieved. Rapid ELISA progesterone kits were used to identify the optimum time for insemination. PMID:8229942

    Balaguer-Martí, José-Carlos; Aloy-Prósper, Amparo; Peñarrocha-Oltra, David

    2016-01-01

    Background In the third molar surgery, it is important to focus not only on surgical skills, but also on patient satisfaction. Classically studies have been focused on surgery and surgeon’s empathy, but there are non-surgical factors that may influence patient satisfaction. Material and Methods A cross-sectional study was performed on 100 patients undergoing surgical extractions of impacted mandibular third molars treated from October 2013 to July 2014 in the Oral Surgery Unit of the University of Valencia. A questionnaire (20 questions) with a 10-point Likert scale was provided. The questionnaire assessed the ease to find the center, the ease to get oriented within the center, the burocratic procedures, the time from the first visit to the date of surgical intervention, waiting time in the waiting room, the comfort at the waiting room, the administrative staff (kindness and efficiency to solve formalities), medical staff (kindness, efficiency, reliability, dedication), personal data care, clarity in the information received (about the surgery, postoperative care and resolution of the doubts), available means and state of facilities. Outcome variables were overall satisfaction, and recommendation of the center. Statistical analysis was made using the multiple linear regression analysis. Results Significant correlations were found between all variables and overall satisfaction. The multiple regression model showed that the efficiency of the surgeon and the clarity of the information were statistically significant to overall satisfaction and recommendation of the center. The kindness of the administrative staff, available means, the state of facilities and the comfort at the waiting room were statistically significant to the recommendation of the center. Conclusions Patient satisfaction directly depends on the efficiency of the surgeon and clarity of the clinical information received about the procedure. Appreciation of these predictive factors may help clinicians

  9. INCIDENCE OF ACUTE MYELOID LEUKEMIA AFTER BREAST CANCER

    Caterina Giovanna Valentini

    2011-12-01

    Full Text Available Breast cancer is the most frequent cancer among women and the leading cause of death among middle-aged women. Early detection by mammography screening and improvement of therapeutic options have increased breast cancer survival rates, with the consequence that late side effects of cancer treatment become increasingly important. In particular, patients treated with adjuvant chemotherapy regimens, commonly including alkylating agents and anthracyclines, are at increased risk of developing leukemia, further enhanced by the use of radiotherapy. In the last few years also the use of growth factors seems to increase the risk of secondary leukemia. The purpose of this review is to update epidemiology of therapy-related myeloid neoplasms occurring in breast cancer patients

  10. Non-surgical treatment of peri-implantitis with the adjunctive use of an 810-nm diode laser

    Marisa Roncati

    2013-01-01

    Full Text Available An 810-nm diode laser was used to non-surgically treat a 7-mm pocket around an implant that had five threads of bone loss, BoP+, and exudate, and the patient was followed up for 5 years. Non-surgical treatment, home care reinforcement, clinical indices records, and radiographic examination were completed in two consecutive 1-h appointments within 24 h. The patient was monitored frequently for the first 3 months. Subsequently, maintenance debridement visits were scheduled at 3-month intervals. The patient had a decreased probing pocket depth and a negative BoP index compared to initial clinical data, and the results were stable after 1 year. After 5 years of follow-up visits, there appeared to be rebound of the bone level radiographically. Within the limits of this case report, conventional non-surgical periodontal therapy with the adjunctive use of an 810-nm diode laser may be a feasible alternative approach for the management of peri-implantitis. The 5-year clinical and radiographic outcomes indicated maintenance of the clinical improvement.

  11. Non-surgical spinal decompression therapy: does the scientific literature support efficacy claims made in the advertising media?

    Daniel Dwain M

    2007-05-01

    Full Text Available Abstract Background Traction therapy has been utilized in the treatment of low back pain for decades. The most recent incarnation of traction therapy is non-surgical spinal decompression therapy which can cost over $100,000. This form of therapy has been heavily marketed to manual therapy professions and subsequently to the consumer. The purpose of this paper is to initiate a debate pertaining to the relationship between marketing claims and the scientific literature on non-surgical spinal decompression. Discussion Only one small randomized controlled trial and several lower level efficacy studies have been performed on spinal decompression therapy. In general the quality of these studies is questionable. Many of the studies were performed using the VAX-D® unit which places the patient in a prone position. Often companies utilize this research for their marketing although their units place the patient in the supine position. Summary Only limited evidence is available to warrant the routine use of non-surgical spinal decompression, particularly when many other well investigated, less expensive alternatives are available.

    2014-01-01

    Key Clinical Message We report a rare case of metastasis-induced acute pancreatitis (MIAP) from small cell lung cancer (SCLC) diagnosed on autopsy, indicating a diagnosis of MIAP with SCLC. Our case suggests that MIAP can arise as a complication of SCLC and has an extremely poor prognosis.

  14. Ginseng Extract Enhances Anti-cancer Effect of Cytarabine on Human Acute Leukemia Cells

    Yiju Hou

    2015-02-01

    Full Text Available Ginseng as a traditional medicine is well known to exhibit various pharmacological effects. Ginsenoside Rg3 is the active ingredient extracted from ginseng. The pharmacological modulatory effects of Rg3 on multidrug resistant cancer cells are reported in the present study. Cytarabine is a chemotherapeutic agent for the treatment of acute leukemia. However, this compound has serious side effects at high doses, for example hematopoiesis depression. In this study, using hl60 human leukemia cells, we investigated the possible synergistic anti-cancer effects between ginseng extract Rg3 and cytarabine on acute myeloid leukemia cells. Results of this study demonstrate that Rg3 can enhance the anti-proliferation effect of cytarabine on hl60 cells and may decrease the dosage of cytarabine needed for acute myeloid leukemia treatment.

  15. Pathology of breast cancer in women irradiated for acute postpartum mastitis

    The gross and microscopic pathology of breast cancers in women irradiated for acute postpartum mastitis was compared to the breast cancers found in the sisters of the irradiated women. In considering the lesions in the two populations, the size, location, histologic type, histologic grade, inflammatory response, lymphatic and blood vascular invasion, nipple involvement, axillary lymph node metastases, and menopausal status at the time of diagnosis were statistically indistinguishable. The only parameter that was different in the two populations was the desmoplastic response to the malignant lesion. The control population had more marked fibrosis within the cancers compared with the irradiated women

    Full Text Available Los pacientes adultos internados por una enfermedad no quirúrgica tienen un riesgo alto de padecer una tromboembolia venosa y pueden desarrollar alguna forma de esta enfermedad cuando no reciben un tratamiento preventivo adecuado. Los objetivos de este estudio prospectivo, analítico, observacional y transversal, fueron: 1 determinar cuál es el porcentaje de pacientes adultos internados por una enfermedad aguda no quirúrgica en el Hospital de Clínicas José de San Martín, Universidad de Buenos Aires, que tienen indicación de tromboprofilaxis, 2 establecer cuántos de ellos reciben un tratamiento preventivo para la tromboembolia venosa, y 3 comprobar cuántos estaban medicados con alguna forma de tromboprofilaxis sin tener causas que justificaran este tratamiento. Se estudiaron 93 pacientes durante un lapso de 72 horas consecutivas. Se encontró que el 90.3% de ellos necesitaba un tratamiento preventivo para la tromboembolia venosa y el 76.2% de estos enfermos recibían tromboprofilaxis farmacológica. Un 33.3% de los pacientes internados tenía indicado un tratamiento farmacológico preventivo sin tener una causa que justificara esta prescripción. El porcentaje encontrado de pacientes tratados con tromboprofilaxis es más alto que el comunicado en otros estudios observacionales.Adult patients hospitalized for a non-surgical condition, usually have a high risk of venous thromboembolism and may develop some form of this disease when they do not receive appropriate preventive treatment. The objectives of this prospective, analytical, observational and cross-sectional study were: 1 to determine what percentage of adult patients hospitalized for a non-surgical acute condition at the Hospital de Clínicas José de San Martín, Universidad de Buenos Aires, had indication for preventive thromboprophylaxis, 2 to establish how many of them had been prescribed a preventive treatment of venous thromboembolism, 3 to establish how many of them had been

  17. A case of acute myelogenous leukemia following aplastic anemia after radiotherapy and chemotherapy for breast cancer

    A 53 years old mastectomized woman for breast cancer treated with radiotherapy (total doses 12,600 rad) and with long term oral administration of cyclophosphamide (CPM) and ftorafur (FT), developed aplastic anemia and thereafter acute myelogenous leukemia. About six months after discontinuation of the above therapies, she developed anemia and leukopenia and was referred to our clinic. Hematological improvement was obtained by the administration of anabolic hormone, however, two months later she became pancytopenic again. At that time, quite atypical myeloblasts contained peroxidase positive granules, were found 39% in the peripheral blood and 89.4% in the bone marrow, respectively. Leukemic hiatus was present. A bone marrow biopsy revealed coexistence of leukemic cells and breast cancer cells. A diagnosis of breast cancer complicated with acute myelogenous leukemia was made. A combined therapy of adriamycin, CPM and FT was ineffective. OAP regimen of vincristine, cytosine arabinoside and predonisolone revealed transient hematologic improvement. Finally, the patient died of septicemia due to klebsiella. Autopsy revealed wide spread coexistence of leukemia and cancer in the bone marrow, liver, and thyroid. The authors discuss some possible explanations for development of acute leukemia after radiotherapy and chemotherapy. (author)

  18. Management of cardiac device infections: A retrospective survey of a non-surgical approach combining antibiotic therapy with transvenous removal.

    Pacemakers (PMs) and implantable cardioverter defibrillators (ICDs) have become life-saving therapeutic tools for patients with cardiac arrhythmia. Complications include thrombosis, embolism and infections at a highly variable rate. Surgical removal of the infected device has been perceived as the only way to guarantee a successful outcome and to reduce the high risk of mortality. Recently, a transvenous extraction method has been developed to remove infected intracardiac leads without sternotomy. This survey was designed to evaluate the outcome of an approach combining antibiotic therapy with non-surgical transvenous complete removal for the management of cardiac device infections (CDIs). We reviewed case-histories of 121 patients (105 with PM and 16 with ICD infections). The aim of our retrospective survey was to ascertain that a non-invasive transvenous complete removal of the infected devices is safe and effective when associated with appropriate antibiotic therapy starting 10 days before the procedure and extending to at least three weeks after. The infected devices were successfully removed in all patients with a non-surgical transvenous technique. The infections were most frequently caused by coagulase-negative staphylococci (70%), Staphylococcus aureus (14%), and Gram-negative rods (12%). Polymicrobial infections were documented in 19 patients and represent 16% of all device-related infections. The removal of the devices was done during antibiotic therapy, administered for a median of 26 days (range 23 to 45 days). Neither fatalities nor relapse of infections were recorded in the patient population during the one-year follow-up visits. According to our experience, CDIs can be treated with antibiotic therapy and non-surgical removal of the entire infected device, thus allowing a successful reimplantation. This procedure prevents recurrent infections and operative mortality. PMID:16736884

  19. A method for analysis of cancer incidence in atomic bomb survivors, with application to acute leukemia

    Some statistical methodology developed for the analysis of the effect of radiation on cancer incidence is described. The methods presented make use of grouped data for estimation of and testing hypotheses about temporal aspects of the radiogenic effects on cancer incidence. The suggested approach is reviewed by its application to recent data on acute leukemia incidence in the RERF Life Span Study sample. The results of these analyses suggest that, although the temporal pattern of the radiogenic excess differs markedly by age at the time of the bomb (ATB), there is no statistically significant evidence of differences in total excess leukemia by age ATB throughout the study period.

    Andrea Bonetto; Tufan Aydogdu; Noelia Kunzevitzky; Guttridge, Denis C.; Sawsan Khuri; Koniaris, Leonidas G.; Teresa A Zimmers

    2011-01-01

    BACKGROUND: Cachexia, or weight loss despite adequate nutrition, significantly impairs quality of life and response to therapy in cancer patients. In cancer patients, skeletal muscle wasting, weight loss and mortality are all positively associated with increased serum cytokines, particularly Interleukin-6 (IL-6), and the presence of the acute phase response. Acute phase proteins, including fibrinogen and serum amyloid A (SAA) are synthesized by hepatocytes in response to IL-6 as part of the i...

  4. The Study on Acute and Subacute Toxicity and Sarcoma-180 Anti-cancer Effects of Vermilionum

    Ki-Rok Kwon

    2003-12-01

    Full Text Available Background & Methods : In order to measure the acute and subacute toxicity of Vermilionum and it's anti-cancer effects, Sarcoma-180 abdominal cancer cells were injected intravenously. The following results were obtained after measuring the survival rate, toxicity of the NK cells, and IL-2 productivity. Results : 1. It was impossible to measure LD50 value in the acute toxicity test and no toxic effects were witnessed in the clinical observation. 2. No significant differences were shown in the weight changes between the experiment groups and the control group in the acute toxicity test. 3. No peculiar toxic effects were shown in the subacute toxicity test and the weight changes were insignificant between the experiment groups and the control group. 4. In measuring the survival rate after inducing abdominal cancer by Sarcoma-180, the experiment groups showed increased of 9,52% compared to the control group. 5. In measuring the activity of NK cells, no significant changes were shown between the experiment groups and the control group. 6. In measuring the productivity of IL-2, significant reduction was shown in the experiment groups compared to the normal group, but no significance was witnessed compared to the control group.

  5. The acute oncologist’s role in managing patients with cancer and other comorbidities

    Kate Shankland

    2015-08-01

    Full Text Available Background: An Acute Oncology Service (AOS is paramount to providing timely and improved pathways of care for patients who are admitted to hospital with cancer-related problems or suspected cancer. Objective: To establish an AOS pilot study to decide how best to implement such a service locally. Methods: The AOS, which included collaboration between the oncology and palliative care teams at the Northern General Hospital in Sheffield, UK, ensured that the majority of oncology patients in the region received timely assessment by an oncologist if they became acutely unwell as a result of their cancer or its treatment. The AOS consisted of a thrice-weekly ward round, and daily telephone advice service. Results: We report on patient data during the first 12 months of the pilot study. Delivery of the AOS enhanced communication between the services and provided inter-professional education and support, resulting in earlier oncological team involvement in the management of patients with cancer admitted under other teams, as well as provision of advice to patients and their caregivers and families. Provision of the AOS shortened the mean length of hospital stay by 6 days. Two case studies are presented to illustrate the typical challenges faced when managing these patients. Conclusions: Establishment of the AOS enabled effective collaboration between the oncology and other clinical teams to provide a rapid and streamlined referral pathway of patients to the AOS. Locally, this process has been supported by the development of acute oncology protocols, which are now in use across the local cancer network.

  6. Systematic Review of the Relationship between Acute and Late Gastrointestinal Toxicity after Radiotherapy for Prostate Cancer

    Matthew Sean Peach

    2015-01-01

    Full Text Available A small but meaningful percentage of men who are treated with external beam radiation therapy for prostate cancer will develop late gastrointestinal toxicity. While numerous strategies to prevent gastrointestinal injury have been studied, clinical trials concentrating on late toxicity have been difficult to carry out. Identification of subjects at high risk for late gastrointestinal injury could allow toxicity prevention trials to be performed using reasonable sample sizes. Acute radiation therapy toxicity has been shown to predict late toxicity in several organ systems. Late toxicities may occur as a consequential effect of acute injury. In this systematic review of published reports, we found that late gastrointestinal toxicity following prostate radiotherapy seems to be statistically and potentially causally related to acute gastrointestinal morbidity as a consequential effect. We submit that acute gastrointestinal toxicity may be used to identify at-risk patients who may benefit from additional attention for medical interventions and close follow-up to prevent late toxicity. Acute gastrointestinal toxicity could also be explored as a surrogate endpoint for late effects in prospective trials.

  7. Acute toxicity after a diverting stoma and spacer prior to chemoradiation in locally advanced rectal cancer

    Background and purpose: Chemoradiotherapy (CRT) followed by surgery is the standard of care for locally advanced rectal cancer (LARC). For grade ⩾3 acute diarrhea there is a relationship between dose and irradiated small bowel volume. The aim of this study was to evaluate whether combined placement of a diverting stoma and sigmoid spacer (DSSS) led to reduced irradiated small bowel volume and less grade ⩾3 acute diarrhea in the treatment of LARC. Materials/methods: Between 2003 and 2010, 54 of 189 LARC patients treated with CRT in two institutions had a DSSS prior to CRT. Data on patient and treatment characteristics and outcomes were collected retrospectively. Delineation of small bowel was performed with planning CT-scans. CTCAE version 4.0 was used for acute toxicity. Results: Patients with a DSSS had significantly less small bowel volume irradiated up to doses of 20 Gy. This difference was not observed for the higher dose levels. CRT induced grade ⩾3 acute diarrhea was not different between the two groups (8.3% vs. 12.8%; p = 0.41). Conclusion: DSSS is not clearly beneficial to reduce grade ⩾3 acute diarrhea, and it must be considered whether placement of a DSSS is justified for this purpose

  8. Acute toxicity profile in prostate cancer with conventional and hypofractionated treatment

    To compare the acute toxicities in radical treatment of prostate cancer between conventional schedule (C-ARM) with 78 Gy/39 fractions and hypofractionation conformal treatment (H-ARM) with 69 Gy/23 fractions. This prospective double arm study consisted of 217 patients with prostate cancer, 112 in H-ARM and 105 in C-ARM arm. C-ARM received conventional six- field conformal radiotherapy with 78 Gy in 39 fractions while H-ARM received hypofractionation with 69 Gy in 23 fractions. Weekly assessment of acute reactions was done during treatment and with one, and 3 months using RTOG scale. Univariated analysis was performed to evaluate differences between the incidences of acute reaction in the treatment arms. Variables with p value less than 0.1 were included in the multivariated logistic regression. There was no difference between H-ARM versus C-ARM for severity and incidence in genitourinary (GU) and gastrointestinal (GI) acute toxicity. During the treatment comparing H-ARM with C-ARM no differences was observed for GI toxicity (grade 0–3; H-ARM = 45.5%, 34%, 18.7% and 1.8% versus C-ARM = 47.6%, 35.2%, 17.2% and 0). For acute GU toxicity no difference was detected between H-ARM (grade 0–3; 22.3%, 54.5%, 18.7% and 4.5%) and C-ARM (grade 0–3; 25.8%, 53.3%, 17.1% and 3.8%). At the 3- months follow-up, persistent Grade > =2 acute GU and GI toxicity were 2.5% and 1.8% in H-ARM versus 5.7% and 3% in C-ARM (p > 0.05). In univariated and multivariated analyses, there was not any dosimetric predictor for GI and GU toxicity. Our data demonstrate that hypofractionated radiotherapy achieving high biological effective dose using conformal radiotherapy is feasible for prostate cancer, being well tolerated with minimal severe acute toxicity

  9. Association of in vitro radiosensitivity and cancer in a family with acute myelogenous leukemia

    The γ-ray sensitivity of skin fibroblasts from six members of a cancer family was investigated using a colony-forming assay. Fibroblasts from the three members with cancer (two sisters with acute myelogenous leukemia and the mother with cervical carcinoma) showed a significant ( p > 0.05) increase in radiosensitivity, while three members without cancer (the father and two sons) showed a normal radioresponse. The possiblity that the increased γ-ray sensitivity was due to defective DNA repair was investigated using assays for DNA repair replication, single-strand break rejoining, and removal of enzyme-sensitive sites in γ-irradiated DNA. Results of these assays indicate that the kinetics of enzymatic repair of radiogenic DNA damage in general, and the rejoining of single-strand scissions and excision repair of base and sugar radioproducts in partigular, were the same in the cell lines from the sensitive and clinically normal family members

  10. Thrombotic thrombocytopenic purpura and myoglobinuric acute renal failure following radiation therapy in a patient with polymyositis and cervical cancer

    A 73-year-old woman was admitted to receive radiation treatment for uterine cervical cancer, however a complex series of events ensued, leading to death. She developed an acute exacerbation of polymyositis complicated by thrombocytopenic purpura, rhabdomyolysis and acute renal failure. Radiation therapy may have produced an immune disturbance leading to the acute exacerbation of polymyositis. Auto-immune-mediated endothelial damage might have triggered a series of events leading to thrombotic thrombocytopenic purpura. Rhabdomyolysis seemed to be the main cause of acute renal failure.

    Purpose: We have previously shown that intensity-modulated radiotherapy (IMRT) can reduce dose to small bowel, bladder, and bone marrow compared with three-field conventional radiotherapy (CRT) technique in the treatment of rectal cancer. The purpose of this study was to review our experience using IMRT to treat rectal cancer and report patient clinical outcomes. Methods and Materials: A retrospective review was conducted of patients with rectal cancer who were treated at Mayo Clinic Arizona with pelvic radiotherapy (RT). Data regarding patient and tumor characteristics, treatment, acute toxicity according to the Common Terminology Criteria for Adverse Events v 3.0, tumor response, and perioperative morbidity were collected. Results: From 2004 to August 2009, 92 consecutive patients were treated. Sixty-one (66%) patients were treated with CRT, and 31 (34%) patients were treated with IMRT. All but 2 patients received concurrent chemotherapy. There was no significant difference in median dose (50.4 Gy, CRT; 50 Gy, IMRT), preoperative vs. postoperative treatment, type of concurrent chemotherapy, or history of previous pelvic RT between the CRT and IMRT patient groups. Patients who received IMRT had significantly less gastrointestinal (GI) toxicity. Sixty-two percent of patients undergoing CRT experienced {>=}Grade 2 acute GI side effects, compared with 32% among IMRT patients (p = 0.006). The reduction in overall GI toxicity was attributable to fewer symptoms from the lower GI tract. Among CRT patients, {>=}Grade 2 diarrhea and enteritis was experienced among 48% and 30% of patients, respectively, compared with 23% (p = 0.02) and 10% (p = 0.015) among IMRT patients. There was no significant difference in hematologic or genitourinary acute toxicity between groups. In addition, pathologic complete response rates and postoperative morbidity between treatment groups did not differ significantly. Conclusions: In the management of rectal cancer, IMRT is associated with a

A baseline QoL questionnaire (oral health impact profile-14 [OHIP-14] was filled by each patient just before surgery, and only those who were considered to have their QoL "not affected" (total score 14 or less were included in the study. After the extraction, each subject was given a modified form of "health related QoL" [OHIP-14]-instrument to be completed by the 3 rd day-after surgery, and were given the opportunity to review the questionnaire on the 7 th day postoperative review. Results: Total OHIP-14 scores ranged between 14 and 48 (mean ± SD, 26.2 ± 8.3. Majority of the subjects (60% reported, "a little affected." Only few subjects (5.8% reported, "not at all affected," and about 32% reported, "quite a lot." Summation of OHIP-14 scores revealed that QoL was "affected" in 41 subjects (34.2% and "not affected" in 79 subjects (65.8%. More than 30% of subjects reported that their ability to chew, ability to open the mouth and enjoyment of food were affected following tooth extraction. Few subjects (14-34% reported deterioration in their speech and less than 20% of subjects reported that change in their appearance was "affected." Only few subjects (12.5-15.1% reported sleep and duty impairment. Thirty-percent of subjects reported their inability to keep social activities, and 41% were not able to continue with their favorite sports and hobbies. Multiple regression analysis revealed no significant association between age, sex, indications for extraction, duration of

    Full Text Available Abstract Background While it is widely held that non-surgical management should be the first line of approach in patients with lumbar spinal stenosis (LSS, little is known about the efficacy of non-surgical treatments for this condition. Data are needed to determine the most efficacious and safe non-surgical treatment options for patients with LSS. The purpose of this paper is to describe the clinical outcomes of a novel approach to patients with LSS that focuses on distraction manipulation (DM and neural mobilization (NM. Methods This is a prospective consecutive case series with long term follow up (FU of fifty-seven consecutive patients who were diagnosed with LSS. Two were excluded because of absence of baseline data or failure to remain in treatment to FU. Disability was measured using the Roland Morris Disability Questionnaire (RM and pain intensity was measured using the Three Level Numerical Rating Scale (NRS. Patients were also asked to rate their perceived percentage improvement. Results The mean patient-rated percentage improvement from baseline to the end to treatment was 65.1%. The mean improvement in disability from baseline to the end of treatment was 5.1 points. This was considered to be clinically meaningful. Clinically meaningful improvement in disability from baseline to the end of treatment was seen in 66.7% of patients. The mean improvement in "on average" pain intensity was 1.6 points. This did not reach the threshold for clinical meaningfulness. The mean improvement in "at worst" pain was 3.1 points. This was considered to be clinically meaningful. The mean duration of FU was 16.5 months. The mean patient-rated percentage improvement from baseline to long term FU was 75.6%. The mean improvement in disability was 5.2 points. This was considered to be clinically meaningful. Clinically meaningful improvement in disability was seen in 73.2% of patients. The mean improvement in "on average" pain intensity from baseline to long

  14. Inverse Relationship Between Biochemical Outcome and Acute Toxicity After Image-Guided Radiotherapy for Prostate Cancer

    Purpose: Prostate cancer patients exhibit variability in normal tissue reactions and biochemical failure. With the use of image-guided radiotherapy (IGRT), there is a greater likelihood that the differences in normal tissue and tumor response are due to biological rather than physical factors. We tested the hypothesis that prospectively scored acute toxicity is associated with biochemical failure-free rate (BFFR) in prostate cancer patients treated with IGRT. Methods and Materials: We retrospectively analyzed BFFR in 362 patients with localized prostate cancer treated with IGRT. We compared BFFR with prospectively collected Radiation Therapy Oncology Group (RTOG) maximum acute gastrointestinal (GI) and genitourinary (GU) toxicity scores. Median follow-up for all patients was 58.3 months after total radiotherapy doses of 75.6–79.8 Gy. Results: Patients reporting RTOG acute GU or GI toxicity scores of ≥2 were considered “sensitive” (n = 141, 39%) and patients reporting scores <2 were considered “nonsensitive” (n = 221, 61%). When calculating biochemical failure (BF) using the American Society for Therapeutic Radiology and Oncology definition at 5 years, 76% (CI 70–82%) of the “nonsensitive” patients were failure free, compared with only 53% (CI 43–62%) of the “sensitive” patients (log–rank test, p < 0.0001). This difference was also observed using the Phoenix definition; “nonsensitive” 5-year BFFR was 81% (CI 74–86%) vs. “sensitive” BFFR was 68% (CI 58–76%; log–rank test p = 0.0012). The difference in BF between cohorts remained significant when controlled for radiation dose (75.6 vs. 79.8 Gy), prognostic stratification (T category, prostate-specific antigen, and Gleason score), and prostate volume. Conclusions: This study unexpectedly shows that prostate cancer patients who develop ≥Grade 2 RTOG acute toxicity during radiotherapy are less likely to remain BFF at 5 years. These results deserve further study and, if validated

  16. Efficacy of injections of phosphatidylcholine into fat deposits-a non-surgical alternative to liposuction in body-contouring

    Karl-G Heinrich

    2005-01-01

    Full Text Available Injecting phosphatidylcholine has been used in South America as a non-surgical treatment in body contouring. The objective of this study was to demonstrate the efficacy of injecting phosphatidylcholine in the reduction of localised fat deposits. 86 patients were included in the study. Patients received 1-3 treatments in localised fat deposits in various areas of the body using phosphatidylcholine. After treatment with phosphatidylcholine (250 mg / 5 ml, fat deposits show an average circumferential reduction per application of 2.70 cm. No patient showed irregularities, dimples or any serious side effect after treatment. Results remained stable during the time of follow up. All patients showed remarkable reductions of the fat deposits treated with phosphatidylcholine. Using the correct technique, injecting phosphatidylcholine may be a safe and efficacious alternative to liposuction in patients objecting to surgery.

    1992-09-01

    Prior to non-surgical therapy of gallstones it is important to assess their number and size. In order to evaluate the accuracy of ultrasound (US) and oral cholecystography (OCG) in counting and measuring gallstones, a prospective blind study was conducted to compare the results of US (n = 99) and OCG (n = 36), either alone or in combination (n = 34), with the number and size of gallstones retrieved after cholecystectomy. The number of gallstones was accurately estimated by US and OCG in 74% and 69% of the cases, respectively. In assessing the presence of up to three, five or 10 gallstones both US and OCG proved reliable. In measuring the size of gallstones, there was 19% accuracy with US compared with only 3% with OCG. With an accepted measurement error of 3 mm these values increased to 80% for US and 44% for OCG. US proved more reliable than OCG in discriminating gallstones smaller or larger than 10 mm and smaller or larger than 20 mm, but with US, detection of gallstones larger than 30 mm was problematic. Both US and OCG underestimated gallstone size. The combination of both techniques did not significantly improve the assessment of either number or size of gallstones compared with the results obtained with US or OCG alone. It is concluded that (1) both US and OCG have some limitations in assessing the number and size of gallstones, (2) the combination of both examinations does not improve accuracy, and (3) patient selection for non-surgical treatment of gallstones can be started by US alone.

    Chemotherapy remains the first-choice option for adjuvant therapy in breast cancer. Here, we investigated the impact of the first chemotherapic cycle of doxorubicin on the plasmatic-proteomic profiling of women diagnosed with breast cancer (n = 87). Blood samples were obtained from the same patient before and after doxorubicin infusion (1 h, 60 mg/m(2)) and processed for label-free LC-MS proteomic screening. A total of 80 proteins were downregulated after chemotherapy. In silico analysis revealed that the main biological process enrolled was inflammation and canonical pathways involving acute phase proteins. TNF-α, IL-1β, IL-12, TGF-β1, clusterin, and gelsolin were chosen as relevant for further validation. All selected targets presented reduced plasmatic levels after treatment. Our results indicate that doxorubicin downregulated acute phase proteins immediately after its infusion. Since such proteins are cancer promoting, its downregulation could support the effectiveness of doxorubicin along treatment. PMID:26472721

  20. Intensity-Modulated Radiation Therapy Significantly Improves Acute Gastrointestinal Toxicity in Pancreatic and Ampullary Cancers

    Purpose: Among patients with upper abdominal malignancies, intensity-modulated radiation therapy (IMRT) can improve dose distributions to critical dose-limiting structures near the target. Whether these improved dose distributions are associated with decreased toxicity when compared with conventional three-dimensional treatment remains a subject of investigation. Methods and Materials: 46 patients with pancreatic/ampullary cancer were treated with concurrent chemoradiation (CRT) using inverse-planned IMRT. All patients received CRT based on 5-fluorouracil in a schema similar to Radiation Therapy Oncology Group (RTOG) 97-04. Rates of acute gastrointestinal (GI) toxicity for this series of IMRT-treated patients were compared with those from RTOG 97-04, where all patients were treated with three-dimensional conformal techniques. Chi-square analysis was used to determine if there was a statistically different incidence in acute GI toxicity between these two groups of patients. Results: The overall incidence of Grade 3-4 acute GI toxicity was low in patients receiving IMRT-based CRT. When compared with patients who had three-dimensional treatment planning (RTOG 97-04), IMRT significantly reduced the incidence of Grade 3-4 nausea and vomiting (0% vs. 11%, p = 0.024) and diarrhea (3% vs. 18%, p = 0.017). There was no significant difference in the incidence of Grade 3-4 weight loss between the two groups of patients. Conclusions: IMRT is associated with a statistically significant decrease in acute upper and lower GI toxicity among patients treated with CRT for pancreatic/ampullary cancers. Future clinical trials plan to incorporate the use of IMRT, given that it remains a subject of active investigation.

  1. Development of a Multicomponent Prediction Model for Acute Esophagitis in Lung Cancer Patients Receiving Chemoradiotherapy

    Purpose: To construct a model for the prediction of acute esophagitis in lung cancer patients receiving chemoradiotherapy by combining clinical data, treatment parameters, and genotyping profile. Patients and Methods: Data were available for 273 lung cancer patients treated with curative chemoradiotherapy. Clinical data included gender, age, World Health Organization performance score, nicotine use, diabetes, chronic disease, tumor type, tumor stage, lymph node stage, tumor location, and medical center. Treatment parameters included chemotherapy, surgery, radiotherapy technique, tumor dose, mean fractionation size, mean and maximal esophageal dose, and overall treatment time. A total of 332 genetic polymorphisms were considered in 112 candidate genes. The predicting model was achieved by lasso logistic regression for predictor selection, followed by classic logistic regression for unbiased estimation of the coefficients. Performance of the model was expressed as the area under the curve of the receiver operating characteristic and as the false-negative rate in the optimal point on the receiver operating characteristic curve. Results: A total of 110 patients (40%) developed acute esophagitis Grade ≥2 (Common Terminology Criteria for Adverse Events v3.0). The final model contained chemotherapy treatment, lymph node stage, mean esophageal dose, gender, overall treatment time, radiotherapy technique, rs2302535 (EGFR), rs16930129 (ENG), rs1131877 (TRAF3), and rs2230528 (ITGB2). The area under the curve was 0.87, and the false-negative rate was 16%. Conclusion: Prediction of acute esophagitis can be improved by combining clinical, treatment, and genetic factors. A multicomponent prediction model for acute esophagitis with a sensitivity of 84% was constructed with two clinical parameters, four treatment parameters, and four genetic polymorphisms.

  2. Rates of clinically apparent heparin-induced thrombocytopenia for unfractionated heparin vs. low molecular weight heparin in non-surgical patients are low and similar

    Gerber Jonathan

    2005-04-01

    Full Text Available Abstract With the growing use of low-molecular-weight heparins (LMWH for the treatment and prevention of venous thromboembolism (VTE, it is important to provide an evidence-based comparison with unfractionated heparin (UFH concerning rates of heparin-induced thrombocytopenia (HIT. Such comparisons are essential in clinical decision-making and cost-modeling. In this paper we review data regarding non-surgical (medical patients. We conclude that the lack of uniform evaluation and standardized testing for HIT in the current literature precludes making a reliable estimate of the relative risk of HIT in UFH vs. LMWH in either the treatment or prevention of VTE in non-surgical patients. However, current data suggest that the risk of thrombocytopenia and HIT is low and similar for non-surgical patients who receive either LMWH or UFH.

  4. Protocol for the ProFHER (PROximal Fracture of the Humerus: Evaluation by Randomisation trial: a pragmatic multi-centre randomised controlled trial of surgical versus non-surgical treatment for proximal fracture of the humerus in adults

    Maffulli Nicola

    2009-11-01

    Full Text Available Abstract Background Proximal humeral fractures, which occur mainly in older adults, account for approximately 4 to 5% of all fractures. Approximately 40% of these fractures are displaced fractures involving the surgical neck. Management of this group of fractures is often challenging and the outcome is frequently unsatisfactory. In particular it is not clear whether surgery gives better outcomes than non-surgical management. Currently there is much variation in the use of surgery and a lack of good quality evidence to inform this decision. Methods/Design We aim to undertake a pragmatic UK-based multi-centre randomised controlled trial evaluating the effectiveness and cost-effectiveness of surgical versus standard non-surgical treatment for adults with an acute closed displaced fracture of the proximal humerus with involvement of the surgical neck. The choice of surgical intervention is left to the surgeon, who must use techniques that they are fully experienced with. This will avoid 'learning curve' problems. We will promote good standards of non-surgical care, similarly insisting on care-provider competence, and emphasize the need for comparable provision of rehabilitation for both groups of patients. We aim to recruit 250 patients from a minimum of 18 NHS trauma centres throughout the UK. These patients will be followed-up for 2 years. The primary outcome is the Oxford Shoulder Score, which will be collected via questionnaires completed by the trial participants at 6, 12 and 24 months. This is a 12-item condition-specific questionnaire providing a total score based on the person's subjective assessment of pain and activities of daily living impairment. We will also collect data for other outcomes, including general health measures and complications, and for an economic evaluation. Additionally, we plan a systematic collection of reasons for non-inclusion of eligible patients who were not recruited into the trial, and their baseline

The levels of cystatin C, neutrophil gelatinase-associated lipocalin (NGAL, liver-type fatty acid-binding protein (L-FABP, and interleukin-18 were examined by enzyme immunoassay. It has been established that the risk of early postoperative AKI may be predicted from the baseline urinary levels of cystatin C and LFABP in patients with renal cancer resulting from 15-20-min warm ischemia time during the partial nephrectomy. An approach based on estimation of the baseline urinary levels of cystatin C and L-FABP to be incorporated into a preoperative examination scheme is proposed for surgical treatment policy choosing in patients with renal cancer. A scheme for examining patients with renal cancer is also suggested for the risk of complications and the degree of AKI assessing in the early post-operative period.

  6. Surgical versus non-surgical treatment for vertebral compression fracture with osteopenia: a systematic review and meta-analysis.

    Jia-Bao Guo

    Full Text Available Surgical and non-surgical interventions are the two categories for treatment of vertebral compression fractures (VCFs. However, there is clinical uncertainty over optimal management. This study aimed to examine the safety and effectiveness of surgical management for treatment of VCFs with osteopenia compared with non-surgical treatment.We conducted a systematic search through electronic databases from inception to June 2014, with no limits on study data or language. Randomized controlled trials (RCTs evaluating surgical versus non-surgical interventions for treatment of patients with VCFs due to osteopenia were considered. Primary outcomes were pain and adverse effects. A random-effects model was used to calculate the pooled mean difference (MD or risk ratios with 95% confidence interval (CI.Sixteen reports (11 studies met the inclusion criteria, and provided data for the meta-analysis with a total of 1,401 participants. Compared with conservative treatment, surgical treatment was more effective in reducing pain (short-term: MD -2.05, 95% CI -3.55 to -0.56, P=0.007; mid-term: MD -1.70, 95% CI -2.78 to -0.62, P=0.002; long-term: MD -1.24, 95% CI -2.20 to -0.29, P=0.01 and disability on the Roland-Morris Disability score (short-term: MD -4.97, 95% CI -8.71 to -1.23, P=0.009, as well as improving quality of life on the Short-Form 36 Physical Component Summary score (short-term: MD 5.53, 95% CI 1.45 to 9.61, P=0.008 and the Quality of Life Questionnaire of the European Foundation for Osteoporosis score (short-term: MD -5.01, 95% CI -8.11 to -1.91, P=0.002. Indirect comparisons between vertebroplasty and kyphoplasty found no evidence that the treatment effect differed across the two interventions for any outcomes assessed. Compared with the sham procedure, surgical treatment showed no evidence of improvement in pain relief and physical function. Based on these two comparisons, no significant difference between groups was noted in the pooled results

  7. Morbidity associated to the transfusion support in pediatric patients with acute leukemia in the National Cancer Institute

    Acute leukemia represents the most common cancer in pediatrics. The current treatments made necessary a hematological support which increases the risks of complications, like fever, immunologic reaction, infections and, graft versus host disease. The objective of the present study was to determine the morbidity associated with transfusion support in pediatric patients with acute leukemia. In the pediatric population with diagnosis of acute leukemia in the INC during one and half year, the morbidity associated with transfusions was low and couldn't be related to the treatment given to the transfused products

    Full Text Available Acute respiratory distress syndrome is a clinical, pathophysiological and radiographic pattern that has signs of pulmonary edema occur without elevated pulmonary venous pressures. Clinical presentation and progression of acute respiratory distress syndrome are followed by frequently ordered portable chest X-ray in critically ill patients. We evaluated chest radiographs of ten cancer and other six critical care pediatric patients. The parenchymal imaging of lung in patients with cancer was reported the same as that of other critically ill children despite underlying pathophysiological variations in our investigation.

  9. Topical betamethasone for the prevention of acute radiation dermatitis in breast cancer patients

    Background: Acute radiation dermatitis is a very common side effect of radiation therapy in large numbers of cancers including breast cancer. Despite high prevalence rate of acute radiation dermatitis and also wet desquamation, a few trials on prophylaxis of this complication using topical treatment have been conducted. Despite effectiveness of topical corticosteroids in treatment of acute radiation dermatitis which are focused in the literature, yet there are some controversy about their usage in this regard. For this reason we attempted to investigate this subject via conducting a clinical trial. Materials and Methods: This trial included 76 patients with pathologic diagnosis of breast cancer for whom radiotherapy has been planned. Patients were 27-70 years old. Patients with radical mastectomy received 5000 cGy within 5 weeks, and those with conservative surgery received 6000 cGy within 6 weeks devided in 200 centigray fractions. Patients were divided randomly into two groups, betamethasone and placebo, 38 patients in each group. In placebo group, 3 patients did not attend for weekly assessment. Additional one patient did not refer during follow-up period. Thus, they were excluded from the study. One group was given betamethasone o.1% and other group was administered base of ointment as placebo. All patient consumed drug or placebo from the 1st day of treatment until one week after treatment completion as twice daily within tangential field. Patients were monitored for assessing dermatitis severity and its symptoms and also possible drug adverse effects one week after the therapy commenced and afterwards by one-week intervals as well as in an appointed day. Three weeks after termination of therapy, patients were also visited, and each examination provided information about dermatologic complications which were registered in the questionnaire. Results: Mean times development of dermatitis in both betamethasone and placebo groups were 3.2500 and 2.2571 (weeks

    2006-12-15

    To evaluate acute toxicities in cervix cancer patients receiving intensity modulated whole pelvic radiation therapy (IM-WPRT). Between August 2004 and April 2006, 17 patients who underwent IM-WPRT were analysed. An intravenous contrast agent was used for radiotherapy planning computed tomography (CT). The central clinical target volume (CTV) included the primary tumor, uterus, vagina, and parametrium. The nodal CTV was defined as the lymph nodes larger than 1 cm seen on CT and the contrased-enhanced pelvic vessels. The planning target volume (PTV) was the 1-cm expanded volume around the central CTV, except for a 5-mm expansion from the posterior vagina, and the nodal PTV was defined as the nodal CTV plus a 1.5 cm margin. IM-WPRT was prescribed to deliver a dose of 50 Gy to more than 95% of the PTV. Acute toxicity was assessed with common toxicity criteria up to 60 days after radiotherapy. Grade 1 nausea developed in 10 (58.9%) patients, and grade 1 and 2 diarrhea developed in 11 (64.7%) and 1 (5.9%) patients, respectively. No grade 3 or higher gastrointestinal toxicity was seen. Leukopenia, anemia, and thrombocytopenia occurred in 15 (88.2%). 7 (41.2%), and 2 (11.8%) patients, respectively, as hematologic toxicities. Grade 3 leukopenia developed in 2 patients who were treated with concurrent chemoradiotherapy. IM-WPRT can be a useful treatment for cervix cancer patients with decreased severe acute toxicities and a resultant improved compliance to whole pelvic irradiation.

    2010-01-01

    Full Text Available Introduction: It is a well established fact that periodontitis is caused by a group of highly specific microorganisms, organized as a bio-film on the tooth surface. Hence, therapeutic modalities are directed against elimination or adequate suppression of these organisms. Thorough debridement of these sites is possible mainly by scaling and root planing (SRP and open- flap debridement in deeper sites. Open- flap debridement includes conventional surgical procedures such as the modified Widman flap procedure. Surgical procedures, however, have a number of disadvantages and hence efforts have been on at improving various non-surgical approaches, which are directed more specifically at the microbial nature of periodontal disease. Use of local drug-delivery devices is one such approach. The combined therapy of SRP and local drug delivery has been showing promising results in improving all the parameters in periodontal disease. Materials and Methods: This study compares the clinical, as well as, microbiological results of a split-mouth trial using modified Widman flap and non-surgical therapy of SRP and the use of a controlled release drug-delivery device (Chlorhexidine chip, in the management of moderate to deep pockets. Results and Conclusion: The results showed that the non-surgical most sites subjected to the non-surgical treatment were found to be maintainable without further deterioration, during the study period.

    Full Text Available Introduction: The present study aimed to evaluate the Effect of topical tetracycline gel application with non surgical periodontal therapy on HbA1c and lipid profile in type 2 diabetic patients. Methods: A total of 30 type 2 diabetic patients were randomly divided into two groups. The first group received scaling and root planning, whereas the second group received scaling and root planning with topically applied tetracycline gel. Clinical factors such as GI, PI, PPD and biochemical factors such as HbA1c and lipid profile were assessed in beginning of study and 3 months later. Results: Comparing the clinical factors between the two groups revealed that periodontal pocket depth significantly reduced in tetracycline-received group. Regarding the biochemical factors, triglyceride levels decreased significantly in tetracycline-received group. No significant difference was observed between the two groups in regard with other clinical and biochemical factors. Conclusion: The study findings demonstrated that clinical and biochemical parameters have been improved after non surgical periodontal treatment in both groups. Although it seems that application of topical tetracycline gel combined with non-surgical periodontal therapy is effective in improvement of some clinical and biochemical factors like PPD and TG, it doesn’t offer any superiority in regard with other factors compared to mere non surgical periodontal therapy.

  17. Acute mucosal reactions in patients with advanced head and neck cancer treated with concurrent chemoradiotherapy

    We conducted a clinical study to analyze the acute reactions in the oral cavity and the oropharyngeal (OCOPH) mucosa in patients with advanced head and neck cancer (HNC) undergoing a definitive treatment consisted of 3-D conformal radiotherapy combined with concomitant chemotherapy. Twenty nine patients with HNC who were treated between February 2008 and October 2009 were included in the study. The median age was 55 years (range 29-70). The site distribution was as follows: oropharynx, 20.7%; hypopharynx, 41.4%; larynx, 37.9%. The radiation technique used for 3-D conformal radiotherapy was named 'oblique photon fields' technique. The OCOPH mucosa as a critical normal tissue was delineated in every patient. Extraction of planning target volume (PTV50) from the volume of OCOPH mucosa led to formation of an OCOPH mucosa with extracted PTV50 (OCOPHEx mucosa). Acute mucosal reactions were recorded using Radiation Therapy Oncology Group (RTOG) grading system. The duration of a maximum grade of reaction was also recorded. A time intensity parameter, so-called Severity-Time Units (STU), quantifying the area under the acute reaction curve, was used to express the intensity of mucositis over time in every patient. Grade 3 acute mucosal reaction was manifested in 19 patients (65.5%). The median duration of confluent mucositis was 21 days (range 14-35). The STU less than 1000 mm2 and the STU more than 1500 mm2 was calculated in equal number of patients (9 patients, or 31.0%). Statistically significant difference in the distribution of the grade 3 reaction was found among patients with different site of the primary tumor (p = 0.003). Statistically significant difference was found between the grade of the acute mucositis and the volume of OCOPHEx mucosa, the dose in 50% of the volume of OCOPHEx (D50%, OCOPHEx) mucosa, and the mean dose to OCOPHEx mucosa (p = 0.02, p = 0.0002, p = 0.00001, respectively). The tested relation between STU and delineated volumes (PTV50 and OCOPHEx

    Full Text Available Background: Chemo-radiotherapy has become the standard of care for loco-regionally advanced head and neck cancers. Platinum based regimens are the most effective. Although benefits are proven with chemo-radiation, acute toxicities are markedly increased. The dose and delivery schedules of Cisplatin have ranged from intermittent higher dose [100 mg/m2] every 3 weeks to low dose [6 mg/m2] daily administration. At present there is no data indicating which regimen is superior. Purpose: To compare acute toxicities of two chemotherapy schedules for head and neck cancers. Materials and Methods: A total of 83 head and neck cancer patients treated with two schedules of concurrent chemo RT were analyzed, retrospectively, for treatment toxicity. In group A [51 patients], chemotherapy [CT] was administered on week 1, 4 and 7 [cisplatin 100 mg/m2] over a period of 2-3 days. In group B [32 patients], CT was delivered weekly [cisplatin 40 mg/m2]. Radiotherapy dose was 7000 cGy in 35 fractions for definitive concurrent chemo-radiation and 6600 cGy in 33 fractions for adjuvant treatment. Results: Group B patients had increased grade III skin and hematological toxicity, where as patients in group A had more pharyngeal toxicity. Treatment interruptions and percentage of weight loss were higher in group B. Weekly CT schedule had higher rate of severe mucositis, which was statistically significant on both univariate [ P =0.005] and multivariate [ P =0.007] analysis. Conclusions: Three weekly CT is less toxic than weekly. Weekly CT can be made more acceptable by reducing the dose and using feeding tubes for nutrition.

  19. Systemic antimicrobial therapy (minocycline as an adjunct to non-surgical approach to recurrent chronic generalized gingival hyperplasia

    2014-01-01

    Full Text Available Systemic antibiotic treatment has emerged as a powerful adjunct to conventional mechanical debridement for therapeutic management of the periodontal diseases. The conceptual basis for treating periodontal diseases as infections is particularly attractive in part because of substantial data indicating that these diseases may be associated with specific putative pathogens. Further, discrete groups of patients respond well to systemic antibiotics and exhibit improvement of clinical parameters, including attachment level and inflammation. This bacterial-host interaction, which is ever-so-present in periodontitis, directs us toward utilizing antimicrobial agents along with the routine mechanical debridement. This case report presents a case of a female patient with recurrence of the chronic generalized periodontitis with gingival enlargement, which is treated thrice by referral dentist. A through clinical examination was carried out pre-operatively and treatment was planned with systemic minocycline in conjunction with the conventional non-surgical approach. There was a significant reduction of pocket depth, gain in attachment with dramatic improvement clinically.

    Full Text Available Aim: The aim of the study was to evaluate the relationship between the diabetic status and severity of the periodontal involvement, and also of the non-surgical periodontal therapy on the periodontal status of patients with diabetes mellitus. Materials and method: The study was conducted on 21 patients with type 1 diabetes mellitus (study group and 10 systemically healthy subjects (control group. We examined: the degree of glycemic control (by measuring the glycated hemoglobin, the periodontal and oral hygiene parameters at the baseline and 4 weeks, 6 months and 12 months after the periodontal treatment (scaling and root planning. Results and discussion: Subjects with a poor glycemic control presented a higher percentage of sites with attachment loss, significantly higher amounts of bacterial plaque, sub-gingival calculus and gingival bleeding - when compared with the control group or with subjects with good or moderated glycemic control. In the same group, a rapid recurrence of the deep periodontal pockets was observed after 12 months. Conclusions: A prolonged poor control of glycemia and the time elapsed from the debut of diabetes were closely related with its complications. The comparison between the diabetes and the control groups demonstrated that diabetes mellitus is a risk factor for the periodontal disease.

    Full Text Available Visfatin is a pleiotropic mediator which acts as growth factor, cytokine, enzyme involved in energy including nicotinamide adenine dinucleotide metabolism and has been recently demonstrated to exert several pro-inflammatory functions. The purpose of this study is to evaluate the Visfatin concentration in gingival crevicular fluid (GCF and serum in patients with chronic periodontitis, and to evaluate the effect of non-surgical periodontal therapy on the GCF and serum visfatin concentration. 30 subjects (age range: 25 to 52 years were selected and divided into two groups based on the gingival index, probing depth, periodontal attachment level, and radiologic parameters (bone loss: group 1 (15 subjects with healthy periodontium, group 2 (15 subjects with chronic periodontitis, while, Group 2 patients after 8 weeks of the treatment (scaling and root planning, SRP constituted group 3. GCF samples (by microcapillary pipettes and serum samples (by venipuncture were collected to estimate the levels of Visfatin using enzyme linked immunosorbent assay kit. The mean Visfatin concentration in GCF and serum was observed to be the highest in group 2 and lowest in group 1. While concentration in group 3 was similar to group 1. The concentration of Visfatin in GCF and serum decreased after SRP. The Visfatin concentration in GCF and serum found to be highest in chronic periodontitis group and decreases after treatment. Hence Visfatin values can be considered as an “inflammatory marker” can be explored in future as a potential therapeutic target in the treatment of periodontal disease.

  2. Joint effects of febrile acute infection and an interferon-γ polymorphism on breast cancer risk.

    Yi Su

    Full Text Available BACKGROUND: There is an inverse relationship between febrile infection and the risk of malignancies. Interferon gamma (IFN-γ plays an important role in fever induction and its expression increases with incubation at fever-range temperatures. Therefore, the genetic polymorphism of IFN-γ may modify the association of febrile infection with breast cancer risk. METHODOLOGY AND PRINCIPAL FINDINGS: Information on potential breast cancer risk factors, history of fever during the last 10 years, and blood specimens were collected from 839 incident breast cancer cases and 863 age-matched controls between October 2008 and June 2010 in Guangzhou, China. IFN-γ (rs2069705 was genotyped using a matrix-assisted laser desorption/ionization time-of-flight mass spectrometry platform. Odds ratios (OR and 95% confidence intervals (CIs were calculated using multivariate logistic regression. We found that women who had experienced ≥1 fever per year had a decreased risk of breast cancer [ORs and 95% CI: 0.77 (0.61-0.99] compared to those with less than one fever a year. This association only occurred in women with CT/TT genotypes [0.54 (0.37-0.77] but not in those with the CC genotype [1.09 (0.77-1.55]. The association of IFN-γ rs2069705 with the risk of breast cancer was not significant among all participants, while the CT/TT genotypes were significantly related to an elevated risk of breast cancer [1.32 (1.03-1.70] among the women with <1 fever per year and to a reduced risk of breast cancer [0.63 (0.40-0.99] among women with ≥1 fever per year compared to the CC genotype. A marked interaction between fever frequencies and the IFN-γ genotypes was observed (P for multiplicative and additive interactions were 0.005 and 0.058, respectively. CONCLUSIONS: Our findings indicate a possible link between febrile acute infection and a decreased risk of breast cancer, and this association was modified by IFN-γ rs2069705.

  3. Acute inhibition of myostatin-family proteins preserves skeletal muscle in mouse models of cancer cachexia

    Cachexia, progressive loss of fat and muscle mass despite adequate nutrition, is a devastating complication of cancer associated with poor quality of life and increased mortality. Myostatin is a potent tonic muscle growth inhibitor. We tested how myostatin inhibition might influence cancer cachexia using genetic and pharmacological approaches. First, hypermuscular myostatin null mice were injected with Lewis lung carcinoma or B16F10 melanoma cells. Myostatin null mice were more sensitive to tumor-induced cachexia, losing more absolute mass and proportionately more muscle mass than wild-type mice. Because myostatin null mice lack expression from development, however, we also sought to manipulate myostatin acutely. The histone deacetylase inhibitor Trichostatin A has been shown to increase muscle mass in normal and dystrophic mice by inducing the myostatin inhibitor, follistatin. Although Trichostatin A administration induced muscle growth in normal mice, it failed to preserve muscle in colon-26 cancer cachexia. Finally we sought to inhibit myostatin and related ligands by administration of the Activin receptor extracellular domain/Fc fusion protein, ACVR2B-Fc. Systemic administration of ACVR2B-Fc potently inhibited muscle wasting and protected adipose stores in both colon-26 and Lewis lung carcinoma cachexia, without affecting tumor growth. Enhanced cachexia in myostatin knockouts indicates that host-derived myostatin is not the sole mediator of muscle wasting in cancer. More importantly, skeletal muscle preservation with ACVR2B-Fc establishes that targeting myostatin-family ligands using ACVR2B-Fc or related molecules is an important and potent therapeutic avenue in cancer cachexia.

    1989-07-01

    We reported a rare case of triple cancers with acute lymphoblastic leukemia (ALL) associated with disseminated intravascular coagulopathy (DIC) after the operations of colon cancer and primary lung cancer. A 78-year-old Japanese male, who had been operated upon for colon cancer (adenocarcinoma) on March 1981, metastatic brain tumor (adenocarcinoma) on December 1986, and primary lung cancer (squamous cell carcinoma) on February 1987, was admitted to our hospital because of severe general malaise on December 6 1987. On admission, he had mild hepatosplenomegaly and hemorrhage diathesis such as purpura. Serum LDH increased to 2,515 mU/ml. The white blood cell count was 6,210/microliters with 53% leukemia cells, and the platelet count was 12,000/microliters. A bone marrow was infiltrated with 96.0% leukemia cells. The leukemia cells stained positively for PAS and negatively for peroxidase. Immunological examination of leukemia cells showed that HLA-DR, TdT, B1 and J5 were positive and cytoplasmic Igmu and surface Ig were negative, indicating common ALL. The coagulation studies revealed that the activated partial thromboplastin time was prolonged to 42.0 seconds, FDP increased to 79.9 micrograms/ml, and antithrombin-III decreased to 62%. Chromosome analysis showed a 48, XY, +2, +21q-, t(9;22) karyotype. He was diagnosed as having Ph1 positive ALL associated with DIC. He was treated with vindesine, prednisolone, L-asparaginase, and adriamycin and complete remission (CR) was achieved after two months. But on August 1988, 8 months after CR, ALL and brain tumor relapsed and he died of pneumonia on September 19, 1988. PMID:2810793

    Psychological morbidity is increasingly reported in cancer survivors. The authors' objective was to determine the presence of acute posttraumatic stress disorder (PTSD) symptoms in prostate cancer (PC) patients following radical prostatectomy. Fifteen patients who underwent radical prostatectomy for localized prostate cancer were assessed for the presence of PTSD-related symptoms by completing the Davidson Trauma Scale (DTS), a month following the procedure. A group of 20 patients who underwent surgery for benign prostate hyperplasia (BPH) served as the control group. PTSD total scores were significantly higher in PC patients when compared with BPH patients, whose PTSD scores did not differ from those reported in the general population (32.6 ± 18.5 vs. 11.3 ± 9.7, p = .001). PTSD did not vary among PC patients when adjusted for educational status. PTSD symptoms are common among patients undergoing radical prostatectomy and independent of their educational level. Research investigating these aspects of posttreatment psychological adjustment is needed for developing well-targeted psychological interventions. PMID:20483867

  7. Acute myeloid leukaemia: a paradigm for the clonal evolution of cancer?

    Carolyn S. Grove

    2014-08-01

    Full Text Available Acute myeloid leukaemia (AML is an uncontrolled clonal proliferation of abnormal myeloid progenitor cells in the bone marrow and blood. Advances in cancer genomics have revealed the spectrum of somatic mutations that give rise to human AML and drawn our attention to its molecular evolution and clonal architecture. It is now evident that most AML genomes harbour small numbers of mutations, which are acquired in a stepwise manner. This characteristic, combined with our ability to identify mutations in individual leukaemic cells and our detailed understanding of normal human and murine haematopoiesis, makes AML an excellent model for understanding the principles of cancer evolution. Furthermore, a better understanding of how AML evolves can help us devise strategies to improve the therapy and prognosis of AML patients. Here, we draw from recent advances in genomics, clinical studies and experimental models to describe the current knowledge of the clonal evolution of AML and its implications for the biology and treatment of leukaemias and other cancers.

  8. Two cases of acute leukemia in heavily exposed a-bomb survivors following radiotherapy for breast cancer

    Two cases of acute leukemia in heavily exposed atomic bomb survivors following postoperative 60Co radiotherapy for breast cancer are presented. Case 1, a female who received an estimated dose of 364 rad from the A-bomb at the age of 22, was diagnosed as having left breast cancer 17 years later. At the age of 48, about 8 years after undergoing postoperative 60Co radiotherapy, she developed acute monocytic leukemia. Case 2, a female who received an estimated dose of 594 rad from the A-bomb at the age of 37, was diagnosed as having right breast cancer 22 years later. At the age of 63, 4 years after postoperative 60Co radiotherapy, she was found to have acute erythroleukemia. Both cases had been exposed to the A-bomb in Hiroshima and to therapeutic radiation after developing breast cancer presumably induced by A-bomb exposure. Thus it is proposed that acute leukemia was induced by exposure to large doses of radiation from two sources. (author)

    2003-01-01

    Randomised studies in locally advanced cervical cancer patients showed that cisplatin should be given concurrently with radiotherapy, because of a better long-term survival compared to radiotherapy alone. This increases the relevance of treatment related toxicity. This review summarises the acute an

  10. Rise and fall of subclones from diagnosis to relapse in pediatric B-acute lymphoblastic leukaemia | Office of Cancer Genomics

    There is incomplete understanding of genetic heterogeneity and clonal evolution during cancer progression. Here we use deep whole-exome sequencing to describe the clonal architecture and evolution of 20 pediatric B-acute lymphoblastic leukaemias from diagnosis to relapse. We show that clonal diversity is comparable at diagnosis and relapse and clonal survival from diagnosis to relapse is not associated with mutation burden.

  12. Acute toxicity in prostate cancer patients treated with and without image-guided radiotherapy

    Image-guided radiotherapy (IGRT) increases the accuracy of treatment delivery through daily target localisation. We report on toxicity symptoms experienced during radiotherapy treatment, with and without IGRT in prostate cancer patients treated radically. Between 2006 and 2009, acute toxicity data for ten symptoms were collected prospectively onto standardized assessment forms. Toxicity was scored during radiotherapy, according to the Common Terminology Criteria Adverse Events V3.0, for 275 prostate cancer patients before and after the implementation of a fiducial marker IGRT program and dose escalation from 74Gy in 37 fractions, to 78Gy in 39 fractions. Margins and planning constraints were maintained the same during the study period. The symptoms scored were urinary frequency, cystitis, bladder spasm, urinary incontinence, urinary retention, diarrhoea, haemorrhoids, proctitis, anal skin discomfort and fatigue. Analysis was conducted for the maximum grade of toxicity and the median number of days from the onset of that toxicity to the end of treatment. In the IGRT group, 14228 toxicity scores were analysed from 249 patients. In the non-IGRT group, 1893 toxicity scores were analysed from 26 patients. Urinary frequency ≥G3 affected 23% and 7% in the non-IGRT and IGRT group respectively (p = 0.0188). Diarrhoea ≥G2 affected 15% and 3% of patients in the non-IGRT and IGRT groups (p = 0.0174). Fatigue ≥G2 affected 23% and 8% of patients in the non-IGRT and IGRT groups (p = 0.0271). The median number of days with a toxicity was higher for ≥G2 (p = 0.0179) and ≥G3 frequency (p = 0.0027), ≥G2 diarrhoea (p = 0.0033) and ≥G2 fatigue (p = 0.0088) in the non-IGRT group compared to the IGRT group. Other toxicities were not of significant statistical difference. In this study, prostate cancer patients treated radically with IGRT had less severe urinary frequency, diarrhoea and fatigue during treatment compared to patients treated with non-IGRT.

  14. Hypofractionated radiotherapy after conservative surgery for breast cancer: analysis of acute and late toxicity

    A variety of hypofractionated radiotherapy schedules has been proposed after breast conserving surgery in the attempt to shorten the overall treatment time. The aim of the present study is to assess acute and late toxicity of using daily fractionation of 2.25 Gy to a total dose of 45 Gy to the whole breast in a mono-institutional series. Eighty-five women with early breast cancer were assigned to receive 45 Gy followed by a boost to the tumour bed. Early and late toxicity were scored according to the Radiation Therapy Oncology Group criteria. For comparison, a group of 70 patients with similar characteristics and treated with conventional fractionation of 2 Gy to a total dose of 50 Gy in 25 fractions followed by a boost, was retrospectively selected. Overall median treatment duration was 29 days for hypofractionated radiotherapy and 37 days for conventional radiotherapy. Early reactions were observed in 72/85 (85%) patients treated with hypofractionation and in 67/70 (96%) patients treated with conventional fractionation (p = 0.01). Late toxicity was observed in 8 patients (10%) in the hypofractionation group and in 10 patients (15%) in the conventional fractionation group, respectively (p = 0.4). The hypofractionated schedule delivering 45 Gy in 20 fractions shortened the overall treatment time by 1 week with a reduction of skin acute toxicity and no increase of late effects compared to the conventional fractionation. Our results support the implementation of hypofractionated schedules in clinical practice

  15. Recombinant activated factor VII in the treatment of intractable non-surgical bleeding following major vascular procedures

    Končar Igor B.

    2008-01-01

    Full Text Available INTRODUCTION A recombinant form of activated factor VII (rFVIIa is a haemostatic drug that is approved for use in haemophiliacs with antibodies to factor VIII or factor IX. Most recent studies and clinical experience have shown that rFVIIa (NovoSeven ®, Novo Nordisk A/S, Denmark gives extreme haemostatic effect in patients with severe "non-haemophilic" bleeding produced after trauma and major surgery. OBJECTIVE We present our preliminary experience of the use of rFVIIa in vascular surgery when conventional haemostatic measures are inadequate. METHOD There were 32 patients divided into five groups: Group I - 14 patients with ruptured abdominal aortic aneurysms; Group II - 10 patients with thoracoabdominal aortic aneurysms; Group III - 5 patients with retroperitoneal tumors involving great abdominal vessels; Group IV - 2 patients with portal hypertension and Group V - one patient with iatrogenic injury of brachial artery and vein during fibrinolytic treatment, because of myocardial infarction. RESULTS Clinical improvement was detected following treatment in 29 patients. Bleeding was successfully controlled as evidenced by improved haemodynamic parameters and decreased inotropic and transfusion requirements. CONCLUSION In vascular patients more liberal use of rFVIIa is limited, because no randomized controlled trial has proved its efficacy and safety in such patients; while also keeping in mind that the price of a 4.8 mg of rFVIIa is $4,080. We recommend the use of rFVIIa in vascular surgery only during and after operative treatment of thoracoabdominal aortic aneurysms, ruptured abdominal aortic aneurysms, retroperitoneal tumors involving the aorta and/or inferior vena cava, as well as portal hypertension, when non-surgical massive uncontrolled bleeding are present.

    Several studies have suggested an increase of cardiovascular disease (CVD) risk on periodontitis patients. An enhancement has been demonstrated on both platelet activation and oxidative stress on periodontitis patients, which may contribute for this association. Therefore, the aim of this study was to evaluate the effects of non-surgical periodontal treatment on the l-arginine-nitric oxide (NO)-cyclic guanosine monophosphate (cGMP) pathway and oxidative status in platelets. A total of eight periodontitis patients and eight controls were included in this study. Clinical, laboratory and experimental evaluations were performed on baseline and 90 days after periodontal treatment (except for western blot analysis). The clinical periodontal evaluation included measurements of probing pocket depth (PPD), clinical attachment loss (CAL), % of sites with plaque and % of sites with bleeding on probing. We evaluated: l-[(3)H]arginine influx; nitric oxide synthase (NOS) and arginase enzymes activity and expression; expression of guanylate cyclase and phosphodiesterase-5 enzymes; cGMP levels; platelet aggregation; oxidative status through superoxide dismutase (SOD) and catalase activities, and measurement of reactive oxygen species (ROS) levels and C-reactive protein (CRP) levels. The initial results showed an activation of both l-arginine influx and via system y (+ )L associated with reduced intraplatelet cGMP levels in periodontitis patients and increased systemic levels of CRP. After periodontal treatment, there was a significant reduction of the % of sites with PPD 4-5mm, % of sites with CAL 4-5 mm, and an enhancement in cGMP levels and SOD activity. Moreover, CRP levels were reduced after treatment. Therefore, alterations in the intraplatelet l-arginine-NO-cGMP pathway and oxidant-antioxidant balance associated with a systemic inflammatory response may lead to platelet dysfunction, which may contribute to a higher risk of CVD in periodontitis.

    2010-07-01

    Full Text Available Abstract Background Because previous studies have suggested that motorized non-surgical spinal decompression can reduce chronic low back pain (LBP due to disc degeneration (discogenic low back pain and disc herniation, it has accordingly been hypothesized that the reduction of pressure on affected discs will facilitate their regeneration. The goal of this study was to determine if changes in LBP, as measured on a verbal rating scale, before and after a 6-week treatment period with non-surgical spinal decompression, correlate with changes in lumbar disc height, as measured on computed tomography (CT scans. Methods A retrospective cohort study of adults with chronic LBP attributed to disc herniation and/or discogenic LBP who underwent a 6-week treatment protocol of motorized non-surgical spinal decompression via the DRX9000 with CT scans before and after treatment. The main outcomes were changes in pain as measured on a verbal rating scale from 0 to 10 during a flexion-extension range of motion evaluation and changes in disc height as measured on CT scans. Paired t-test or linear regression was used as appropriate with p Results We identified 30 patients with lumbar disc herniation with an average age of 65 years, body mass index of 29 kg/m2, 21 females and 9 males, and an average duration of LBP of 12.5 weeks. During treatment, low back pain decreased from 6.2 (SD 2.2 to 1.6 (2.3, p Conclusions Non-surgical spinal decompression was associated with a reduction in pain and an increase in disc height. The correlation of these variables suggests that pain reduction may be mediated, at least in part, through a restoration of disc height. A randomized controlled trial is needed to confirm these promising results. Clinical trial registration number NCT00828880

  19. STAT3 activation in skeletal muscle links muscle wasting and the acute phase response in cancer cachexia.

    Andrea Bonetto

    Full Text Available BACKGROUND: Cachexia, or weight loss despite adequate nutrition, significantly impairs quality of life and response to therapy in cancer patients. In cancer patients, skeletal muscle wasting, weight loss and mortality are all positively associated with increased serum cytokines, particularly Interleukin-6 (IL-6, and the presence of the acute phase response. Acute phase proteins, including fibrinogen and serum amyloid A (SAA are synthesized by hepatocytes in response to IL-6 as part of the innate immune response. To gain insight into the relationships among these observations, we studied mice with moderate and severe Colon-26 (C26-carcinoma cachexia. METHODOLOGY/PRINCIPAL FINDINGS: Moderate and severe C26 cachexia was associated with high serum IL-6 and IL-6 family cytokines and highly similar patterns of skeletal muscle gene expression. The top canonical pathways up-regulated in both were the complement/coagulation cascade, proteasome, MAPK signaling, and the IL-6 and STAT3 pathways. Cachexia was associated with increased muscle pY705-STAT3 and increased STAT3 localization in myonuclei. STAT3 target genes, including SOCS3 mRNA and acute phase response proteins, were highly induced in cachectic muscle. IL-6 treatment and STAT3 activation both also induced fibrinogen in cultured C2C12 myotubes. Quantitation of muscle versus liver fibrinogen and SAA protein levels indicates that muscle contributes a large fraction of serum acute phase proteins in cancer. CONCLUSIONS/SIGNIFICANCE: These results suggest that the STAT3 transcriptome is a major mechanism for wasting in cancer. Through IL-6/STAT3 activation, skeletal muscle is induced to synthesize acute phase proteins, thus establishing a molecular link between the observations of high IL-6, increased acute phase response proteins and muscle wasting in cancer. These results suggest a mechanism by which STAT3 might causally influence muscle wasting by altering the profile of genes expressed and

    Full Text Available Abstract Background Carpal tunnel syndrome is a common disorder in hand surgery practice. Both surgical and conservative interventions are utilized for the carpal tunnel syndrome. Although certain indications would specifically indicate the need for surgery, there is a spectrum of patients for whom either treatment option might be selected. The purpose of this systematic review was to compare the efficacy of surgical treatment of carpal tunnel syndrome with conservative treatment Methods We included all controlled trials written in English, attempting to compare any surgical interventions with any conservative therapies. We searched Cochrane Central Register of Controlled Trials (The Cochrane Library Issue 1, 2010, MEDLINE (1980 to June 2010, EMBASE (1980 to June 2010, PEDro (searched in June 2010, international guidelines, computer searches based on key words and reference lists of articles. Two reviewers performed study selection, assessment of methodological quality and data extraction independently of each other. Weighted mean differences and 95% confidence intervals for patient self-reported functional and symptom questionnaires were calculated. Relative risk (RR and 95% confidence intervals for electrophysiological studies and complication were also calculated. Results We assessed seven studies in this review including 5 RCTs and 2 controlled trials. The methodological quality of the trials ranged from moderate to high. The weighted mean difference demonstrated a larger treatment benefit for surgical intervention compared to non surgical intervention at six months for functional status 0.35( 95% CI 0.22, 0.47 and symptom severity 0.43 (95% CI 0.29, 0.57. There were no statistically significant difference between the intervention options at 3 months but there was a benefit in favor of surgery in terms of function and symptom relief at 12 months ( 0.35, 95% CI 0.15, 0.55 and 0.37, 95% CI 0.19 to 0.56.

    Full Text Available Abstract Background A variety of hypofractionated radiotherapy schedules has been proposed after breast conserving surgery in the attempt to shorten the overall treatment time. The aim of the present study is to assess acute and late toxicity of using daily fractionation of 2.25 Gy to a total dose of 45 Gy to the whole breast in a mono-institutional series. Methods Eighty-five women with early breast cancer were assigned to receive 45 Gy followed by a boost to the tumour bed. Early and late toxicity were scored according to the Radiation Therapy Oncology Group criteria. For comparison, a group of 70 patients with similar characteristics and treated with conventional fractionation of 2 Gy to a total dose of 50 Gy in 25 fractions followed by a boost, was retrospectively selected. Results Overall median treatment duration was 29 days for hypofractionated radiotherapy and 37 days for conventional radiotherapy. Early reactions were observed in 72/85 (85% patients treated with hypofractionation and in 67/70 (96% patients treated with conventional fractionation (p = 0.01. Late toxicity was observed in 8 patients (10% in the hypofractionation group and in 10 patients (15% in the conventional fractionation group, respectively (p = 0.4. Conclusions The hypofractionated schedule delivering 45 Gy in 20 fractions shortened the overall treatment time by 1 week with a reduction of skin acute toxicity and no increase of late effects compared to the conventional fractionation. Our results support the implementation of hypofractionated schedules in clinical practice.

  4. A case of acute exacerbation of idiopathic pulmonary fibrosis after proton beam therapy for non-small cell lung cancer

    There have been no reports describing acute exacerbations of idiopathic pulmonary fibrosis after particle radiotherapy for non-small cell lung cancer. The present study describes the case of a 76-year-old Japanese man with squamous cell carcinoma of the lung that relapsed in the left upper lobe 1 year after right upper lobectomy. He had been treated with oral prednisolone 20 mg/day every 2 days for idiopathic pulmonary fibrosis, and the relapsed lung cancer was treated by proton beam therapy, which was expected to cause the least adverse effects on the idiopathic pulmonary fibrosis. Fifteen days after the initiation of proton beam therapy, the idiopathic pulmonary fibrosis exacerbated, centered on the left upper lobe, for which intensive steroid therapy was given. About 3 months later, the acute exacerbation of idiopathic pulmonary fibrosis had improved, and the relapsed lung cancer became undetectable. Clinicians should be aware that an acute exacerbation of idiopathic pulmonary fibrosis may occur even in proton beam therapy, although proton beam therapy appears to be an effective treatment option for patients with idiopathic pulmonary fibrosis.

  5. Acute phase response before treatment predicts radiation esophagitis in non-small cell lung cancer

    Background and purpose: Radiation esophagitis (RE) represents an inflammatory reaction to radiation therapy (RT). We hypothesized that aspects of the physiologic acute phase response (APR) predicts RE. Material and methods: We retrospectively analyzed 285 patients with non-small cell lung cancer (NSCLC) treated with definitive radiation. The primary analysis was the association of pretreatment lab values reflective of the APR with symptomatic (grade ⩾2) RE. Univariate and multivariate odds ratios (ORs) were calculated to test associations of clinical and pretreatment lab values with RE. Optimal cutpoints and multivariable risk stratification groupings were determined via recursive partitioning analysis. Results: Pretreatment platelet counts were higher and hemoglobin levels lower in patients who developed RE (P < 0.05). Based on these two pre-treatment risk factors, an APR score was defined as 0 (no risk factors), 1 (either risk factor), or 2 (both risk factors). APR score was significantly associated with RE in both univariate (OR = 2.3 for each point, 95% confidence interval [CI] 1.5–3.4, P = 0.001) and multivariate (OR = 2.1, 95% CI 1.3–3.4, P = 0.002) analyses. Conclusions: The APR score may represent a novel metric to predict RE. However, pending validation in an independent dataset, caution is advised when interpreting these results given their retrospective and thus exploratory nature

  6. A case of lung cancer associated with acute respiratory distress syndrome after thoracic radiotherapy

    A 73-year-old man presented with dyspnea, cough, fever, appetite loss and stridor due to bronchial stenosis. Fiber-optic bronchoscopy revealed an endobronchial lesion in the right main bronchus and biopsy specimens showed poorly differentiated squamous cell carcinoma. The clinical stage of lung cancer was IIIB (T4N2M0). The patient received 60 Gy in 30 fractions over 43 days to a field including the right hilum and mediastinum. The tumor decreased in size and stenosis of the bronchus disappeared. A week after completion of radiation the patient began to have high grade fever and dyspnea, and progressive hypoxia developed. A chest radiograph showed diffuse bilateral interstitial infiltrates. Despite mechanical ventilation with PEEP and the administration of steroids, he died of respiratory failure three weeks after completion of radiation. Necropsy specimens obtained from the left lung revealed massive deposition of fibrin in the alveolar airspaces associated with hyaline membranes and hyperplasia of type II cells indicating diffuse alveolar damage. The patient had mild pulmonary fibrosis on a CT scan taken before the start of radiotherapy. We conclude that care should be taken if the case has pulmonary fibrosis because radiation therapy can precipitate severe radiation pneumonitis and acute respiratory distress syndrome in such cases.

  7. Acute and late toxicity in prostate cancer patients treated by dose escalated intensity modulated radiation therapy and organ tracking

    To report acute and late toxicity in prostate cancer patients treated by dose escalated intensity-modulated radiation therapy (IMRT) and organ tracking. From 06/2004 to 12/2005 39 men were treated by 80 Gy IMRT along with organ tracking. Median age was 69 years, risk of recurrence was low 18%, intermediate 21% and high in 61% patients. Hormone therapy (HT) was received by 74% of patients. Toxicity was scored according to the CTC scale version 3.0. Median follow-up (FU) was 29 months. Acute and maximal late grade 2 gastrointestinal (GI) toxicity was 3% and 8%, late grade 2 GI toxicity dropped to 0% at the end of FU. No acute or late grade 3 GI toxicity was observed. Grade 2 and 3 pre-treatment genitourinary (GU) morbidity (PGUM) was 20% and 5%. Acute and maximal late grade 2 GU toxicity was 56% and 28% and late grade 2 GU toxicity decreased to 15% of patients at the end of FU. Acute and maximal late grade 3 GU toxicity was 8% and 3%, respectively. Decreased late ≥ grade 2 GU toxicity free survival was associated with higher age (P = .025), absence of HT (P = .016) and higher PGUM (P < .001). GI toxicity rates after IMRT and organ tracking are excellent, GU toxicity rates are strongly related to PGUM

  8. Acute Cardiac Impairment Associated With Concurrent Chemoradiotherapy for Esophageal Cancer: Magnetic Resonance Evaluation

    Purpose: To evaluate acute cardiac effects of concurrent chemoradiotherapy (CCRT) for esophageal cancer. Methods and Materials: This prospective study was approved by the institutional review board, and written informed consent was obtained from all participants. The left ventricular function (LVF) of 31 patients with esophageal cancer who received cisplatin and 5-fluorouracil–based CCRT was evaluated using cardiac cine magnetic resonance imaging. The patients were classified into two groups according to mean LV dose. The parameters related to LVF were compared between before and during (40 Gy) or between before and after CCRT using a Wilcoxon matched-pairs single rank test, and parameter ratios (during/before CCRT, after/before CCRT) were also compared between the groups with a t test. Data were expressed as mean ± SE. Results: In the low LV-dose group (n = 10; mean LV dose 2), LV stroke volume index (38.6 ± 1.56 vs. 29.9 ± 1.60 mL/m2), and LV ejection fraction (56.9% ± 1.79% vs. 52.8% ± 1.15%) decreased significantly (p < 0.05) after CCRT. Heart rate increased significantly (before vs. during vs. after CCRT; 66.8 ± 3.05 vs. 72.4 ± 4.04 vs. 85.4 ± 3.75 beats per minute, p < 0.01). Left ventricle wall motion decreased significantly (p < 0.05) in segments 8 (before vs. during vs. after CCRT; 6.64 ± 0.54 vs. 4.78 ± 0.43 vs. 4.79 ± 0.50 mm), 9 (6.88 ± 0.45 vs. 5.04 ± 0.38 vs. 5.27 ± 0.47 mm), and 10 (9.22 ± 0.48 vs. 8.08 ± 0.34 vs. 8.19 ± 0.56 mm). The parameter ratios of LV end-diastolic volume index, stroke volume index, wall motion in segment 9, and heart rate showed significant difference (p < 0.05) after CCRT between the groups. Conclusions: Concurrent chemoradiotherapy for esophageal cancer impairs LVF from an early treatment stage. This impairment is prominent in patients with high LV dose.

    Radioactive iodine treatment has been widely used for nearly 50 years in the treatment of thyroid cancer to ablate residual thyroid tissue after thyroidectomy and to treat metastatic disease. Leukemia is a rare complication associated with the radioactive iodine therapy. The occurrence of leukemia is known to be related to the cumulative dosage of I-131 more than 37 GBq (1 Ci) and also associated with the intervals of less than 12 months between the repeated doses. We report a case of a 52 year-old female patient with papillary cancer of thyroid who developed acute myelogenous leukemia after the total 20.4 GBq (550 mCi) of I-131 therapy over 3.2 years and palliative radiation therapy ( 3000 cGy) due to multiple bone metastasis of papillary cancer.

  12. A new non-surgically implantable catheter port system for locoregional chemotherapy of the advanced carcinoma of the urinary bladder

    A new method to treat advanced urinary bladder cancer with locoregional chemotherapy has been developed which can be implanted by the radiologist. So far 3 patients with urinary bladder cancer invading the surrounding anatomical structures were treated. A 5F catheter is introduced into the internal iliac artery by the translumbar approach. Then, this catheter is exchanged with a coaxilly assembled catheter port system over a guide wire. A subcutaneous tunnel through the puncture site is formed to receive the port. 10 mg mitomycin were infused three times at intervals of one to three weeks. Computed tomograms and cytoscopy showed complete disappearance of the tumour. (orig.)

  13. Factors determining acute normal tissue reactions during postoperative radiotherapy in endometrial cancer: analysis of 317 consecutive cases

    Background and purpose: Acute radiotherapy reactions are commonly underestimated and under-reported in the literature. Our aim was to evaluate the incidence and risk factors for acute reactions during postoperative radiotherapy in endometrial cancer patients. Material and methods: Performed was detailed retrospective analysis of 317 endometrial cancer patients given postoperative radiotherapy. Two hundred forty seven patients (78%) received both intracavitary (BRT) and external beam irradiation (EBRT), 49 patients (15%) received only BRT and 21 patients (7%) - only EBRT. BRT included radium (Ra) or cesium (Cs). The mean total dose at 0.5 cm for Ra and Cs was 50.5±10.3 Gy and 48.4±15.0 Gy, respectively, and the mean dose rate - 0.47±0.06 Gy/h and 1.42±0.41 Gy/h, respectively. Mean EBRT dose in the ICRU reference point was 49.0±3.7 Gy given in fractions of 1.54-2.49 Gy (mean 2.0±0.17 Gy). Radiotherapy and Oncology Group classification system was employed to score acute reactions. The impact of patient- and treatment-related factors on the risk of acute bowel and urinary bladder reactions was assessed with uni- and multivariate tests. Results: Acute radiotherapy reactions of any grade occurred in 265 patients (84%) including bowel complications in 66% and urinary bladder complications in 36%. There were 21 severe (grade 3 or 4) reactions, all but one seen in the patients treated with combined EBRT and BRT. Higher total dose (P=0.024), higher EBRT dose (P=0.022) and higher age (P=0.026) were correlated with increased acute bowel toxicity in univariate analysis. Multivariate analysis showed that higher EBRT dose (P=0.015) and older age (P=0.016) were independently correlated with the risk of acute bowel events. Higher total dose (P=0.009), BRT dose (P=0.029), BRT dose rate (P=0.004), EBRT fraction size (P=0.007), the use of Cs BRT (P=0.001) and lower parity (P=0.041) were correlated with increased risk of acute bladder toxicity in univariate test.

  15. Predictors of Severe Acute and Late Toxicities in Patients With Localized Head-and-Neck Cancer Treated With Radiation Therapy

    Purpose: Radiation therapy (RT) causes acute and late toxicities that affect various organs and functions. In a large cohort of patients treated with RT for localized head and neck cancer (HNC), we prospectively assessed the occurrence of RT-induced acute and late toxicities and identified characteristics that predicted these toxicities. Methods and Materials: We conducted a randomized trial among 540 patients treated with RT for localized HNC to assess whether vitamin E supplementation could improve disease outcomes. Adverse effects of RT were assessed using the Radiation Therapy Oncology Group Acute Radiation Morbidity Criteria during RT and one month after RT, and the Radiation Therapy Oncology Group/European Organization for Research and Treatment of Cancer Late Radiation Morbidity Scoring Scheme at six and 12 months after RT. The most severe adverse effect among the organs/tissues was selected as an overall measure of either acute or late toxicity. Grade 3 and 4 toxicities were considered as severe. Stepwise multivariate logistic regression models were used to identify all independent predictors (p < 0.05) of acute or late toxicity and to estimate odds ratios (OR) for severe toxicity with their 95% confidence intervals (CI). Results: Grade 3 or 4 toxicity was observed in 23% and 4% of patients, respectively, for acute and late toxicity. Four independent predictors of severe acute toxicity were identified: sex (female vs. male: OR = 1.72, 95% confidence interval [CI]: 1.06–2.80), Karnofsky Performance Status (OR = 0.67 for a 10-point increment, 95% CI: 0.52–0.88), body mass index (above 25 vs. below: OR = 1.88, 95% CI: 1.22–2.90), TNM stage (Stage II vs. I: OR = 1.91, 95% CI: 1.25–2.92). Two independent predictors were found for severe late toxicity: female sex (OR = 3.96, 95% CI: 1.41–11.08) and weight loss during RT (OR = 1.26 for a 1 kg increment, 95% CI: 1.12–1.41). Conclusions: Knowledge of these predictors easily collected in a clinical

    Highlights: → We performed more detailed analysis of CD9 function for CSC properties in B-ALL. → Leukemogenic fusion/Src family proteins were markedly regulated in the CD9+ cells. → Proliferation of B-ALL cells was inhibited by anti-CD9 monoclonal antibody. → Knockdown of CD9 by RNAi remarkably reduced the leukemogenic potential. → CD9-knockdown affected the expression and phosphorylation of Src family and USP22. -- Abstract: Although the prognosis of acute lymphoblastic leukemia (ALL) has improved considerably in recent years, some of the cases still exhibit therapy-resistant. We have previously reported that CD9 was expressed heterogeneously in B-ALL cell lines and CD9+ cells exhibited an asymmetric cell division with greater tumorigenic potential than CD9- cells. CD9+ cells were also serially transplantable in immunodeficient mice, indicating that CD9+ cell possess self-renewal capacity. In the current study, we performed more detailed analysis of CD9 function for the cancer stem cell (CSC) properties. In patient sample, CD9 was expressed in the most cases of B-ALL cells with significant correlation of CD34-expression. Gene expression analysis revealed that leukemogenic fusion proteins and Src family proteins were significantly regulated in the CD9+ population. Moreover, CD9+ cells exhibited drug-resistance, but proliferation of bulk cells was inhibited by anti-CD9 monoclonal antibody. Knockdown of CD9 remarkably reduced the leukemogenic potential. Furthermore, gene ablation of CD9 affected the expression and tyrosine-phosphorylation of Src family proteins and reduced the expression of histone-deubiquitinase USP22. Taken together, our results suggest that CD9 links to several signaling pathways and epigenetic modification for regulating the CSC properties of B-ALL.

  18. Intermittent use of amifostine during postoperative radiochemotherapy and acute toxicity in rectal cancer patients

    From September 1997 through October 1998, 30 patients with stage II/III rectal cancer underwent postoperative radiochemotherapy at our department. All patients had undergone curative (R0) resection and received 50.4 Gy to the pelvis with a 3-field technique using a belly board followed by a boost of 5.4 Gy to the presacral space in conventional fractionation with 1.8 Gy per fraction. 5-FU chemotherapy was administered as 120-hours continuous infusion in the first and fifth radiation week via a central venous catheter in a daily dosage of 1000 mg/m2. All patients were offered to participate in a phase-II study using additional amifostine. Fifteen patients participated and received 500 mg amifostine daily on chemotherapy days (days 1 to 5 and 29 to 33) immediately prior to the daily radiation fraction. Fifteen patients did not participate and served as non-randomized control. The study was approved by the ethical committee of the Martin-Luter-University and informed consent was obtained from all patients. Results: The distribution of patients' characteristics and prognostic parameters was comparable in both groups. Side effects of amifostine were mild and included hypotension (53% grade I, 7% grade II) and nausea (47% grade I, 13% grade II). Antiemetics were not routinely used. All patients completed radiochemotherapy plus amifostine without unplanned breaks or dose reductions. One patients developed a cerebral infraction which was considered to be not related to the use of amifostine. As compared to the non-randomized control group, patients with additional amifostine had less acute skin and bowel toxicity (maximum erythema score 1.47±0.64 without vs 0.87±0.52 with amifostine, p=0.009 and maximum diarrhea score 1.07±1.03 vs 0.40±0.63, p=0.044). Oral 5-FU-related mucositis and hematological toxicity were not significantly different. (orig.)

    The purpose of this systematic review was to summarise the evidence from studies investigating the integration of tumour bed boosts into whole breast irradiation for patients with Stage 0-III breast cancer, with a focus on its impact on acute and late toxicities. A comprehensive systematic electronic search through the Ovid MEDLINE, EMBASE and PubMed databases from January 2000 to January 2015 was conducted. Studies were considered eligible if they investigated the efficacy of hypo- or normofractionated whole breast irradiation with the inclusion of a daily concurrent boost. The primary outcomes of interest were the degree of observed acute and late toxicity following radiotherapy treatment. Methodological quality assessment was performed on all included studies using either the Newcastle-Ottawa Scale or a previously published investigator-derived quality instrument. The search identified 35 articles, of which 17 satisfied our eligibility criteria. Thirteen and eleven studies reported on acute and late toxicities respectively. Grade 3 acute skin toxicity ranged from 1 to 7% whilst moderate to severe fibrosis and telangiectasia were both limited to 9%. Reported toxicity profiles were comparable to historical data at similar time-points. Studies investigating the delivery of concurrent boosts with whole breast radiotherapy courses report safe short to medium-term toxicity profiles and cosmesis rates. Whilst the quality of evidence and length of follow-up supporting these findings is low, sufficient evidence has been generated to consider concurrent boost techniques as an alternative to conventional sequential techniques.

    2015-01-01

    Full Text Available Although involvement of pancreas is a common finding in small cell lung cancer (SCLC, metastasis-induced acute pancreatitis (MIAP is very rare. A 50-year-old female with SCLC who had limited disease and achieved full response after treatment presented with acute pancreatitis during her follow-up. The radiologic studies revealed a small area causing obliteration of the pancreatic duct without mass in the pancreatic neck, and endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA confirmed the metastasis of SCLC. The patient was treated successfully with systemic chemotherapy and radiotherapy delivered to pancreatic field. In SCLC, cases of MIAP can be encountered with conventional computed tomography with no mass image, and positron emission tomography and EUS-FNA can be useful for diagnosis of such cases. Aggressive systemic and local treatment can prolong survival, especially in patients with good performance status.

  1. Efficacy of selective alpha-1 blocker therapy in the treatment of acute urinary symptoms during radiotherapy for localized prostate cancer

    Purpose: To determine the efficacy of an alpha-1 adrenoreceptor blocking agent for acute urinary symptoms in patients treated with radiotherapy for localized prostate cancer. Methods and Materials: Between 1987 and 1995, 743 patients with clinically localized prostate cancer were treated with 3D-CRT. A total of 275 (37%) patients developed Grade 2 acute urinary symptoms as defined by the RTOG morbidity scoring system. Terazosin hydrochloride (THC), a selective alpha-1 adrenoceptor blocking agent, was given to 119 (43%) patients for treatment of their urinary symptoms, whereas nonsteroidal anti-inflammatory medications (NSAID) were administered to 71 patients (26%). Thirty-one patients (11%) were treated with other medications, and 54 (20%) did not seek pharmacologic intervention for their urinary symptoms. Patients were monitored weekly to assess changes in urinary urgency, frequency, and nocturia. Results: Treatment with THC resulted in a significant resolution of urinary symptoms in 79 of 119 patients (66%), while 26 (22%) had moderate improvement, and 14 (12%) had minimal to no response to this drug. In contrast, only 11 of 71 (16%) of the patients treated with NSAIDs experienced significant symptom relief, 20 (28%) had moderate improvement, and 40 (56%) had minimal to no response. The difference in the significant symptomatic improvement between THC and NSAID therapy (66% vs. 16%) was highly significant (p < 0.001). For patients treated with THC, a higher likelihood of significant symptom relief was observed in patients who did not receive neoadjuvant androgen ablation (p = 0.04) and in those who were younger than 65 years of age (p = 0.02). Conclusion: Alpha-1 selective adrenoceptor blocking agents are effective in ameliorating the acute urinary symptoms in patients receiving radiotherapy for localized prostate cancer. Although this was not a randomized prospective study, the data suggest that NSAIDs were less effective in relieving radiation-induced urinary

    DNA repair plays a critical role in response to ionizing radiation (IR) and developing of radiotherapy induced normal tissue reactions. In our study, we investigated the association of radiotherapy related acute side effects, with X-ray repair cross complementing group 1 (XRCC1) and Poly (ADP-ribose) polymerase 1 (PARP1) DNA repair gene expression levels, their changes in protein expression and DNA damage levels in breast cancer patients. The study included 40 women with newly diagnosed breast cancer; an experimental case group (n=20) with acute side effects and the control group (n=20) without side effects. For gene and protein expression analysis, lymphocytes were cultured for 72 h and followed by in vitro 2 Gray (Gy) gamma-irradiation. For detection of DNA damage levels, lymphocytes were irradiated with in vitro 2 Gy gamma-rays and followed by incubation for 72 h. XRCC1 mRNA and protein expression levels were significantly higher in controls than in experimental cases (P=0.020). In terms of DNA damage levels, an increased frequency of micronucleus (MN) was observed in experimental cases versus controls, but this association was not significant (P=0.206). We also observed a significant negative correlation between MN frequency and XRCC1 protein levels in experimental (r=-0.469, P=0.037) vs control (r=-0.734, P<0.001). Our results suggested that decreased XRCC1 expression levels might be associated with the increased risk of therapeutic IR-related acute side effects in patients with breast cancer. PMID:26826460

    Purpose: A prospective cohort study was conducted to evaluate toxicity, quality of life (QOL), and clinical outcomes in patients treated with intensity modulated radiation therapy (IMRT) and concurrent chemotherapy for anal and perianal cancer. Methods and Materials: From June 2008 to November 2010, patients with anal or perianal cancer treated with IMRT were eligible. Radiation dose was 27 Gy in 15 fractions to 36 Gy in 20 fractions for elective targets and 45 Gy in 25 fractions to 63 Gy in 35 fractions for gross targets using standardized, institutional guidelines, with no planned treatment breaks. The chemotherapy regimen was 5-fluorouracil and mitomycin C. Toxicity was graded with the National Cancer Institute Common Terminology Criteria for Adverse Events, version 3. QOL was assessed with the European Organization for Research and Treatment of Cancer (EORTC) QLQ-C30 and CR29 questionnaires. Correlations between dosimetric parameters and both physician-graded toxicities and patient-reported outcomes were evaluated by polyserial correlation. Results: Fifty-eight patients were enrolled. The median follow-up time was 34 months; the median age was 56 years; 52% of patients were female; and 19% were human immunodeficiency virus—positive. Stage I, II, III, and IV disease was found in 9%, 57%, 26%, and 9% of patients, respectively. Twenty-six patients (45%) required a treatment break because of acute toxicity, mainly dermatitis (23/26). Acute grade 3 + toxicities included skin 46%, hematologic 38%, gastrointestinal 9%, and genitourinary 0. The 2-year overall survival (OS), disease-free survival (DFS), colostomy-free survival (CFS), and cumulative locoregional failure (LRF) rates were 90%, 77%, 84%, and 16%, respectively. The global QOL/health status, skin, defecation, and pain scores were significantly worse at the end of treatment than at baseline, but they returned to baseline 3 months after treatment. Social functioning and appetite scores were

    Full Text Available Pathological fractures in cancer patient cause severe pain that is difficult to control pharmacologically. Even with good pain relief at rest, breakthrough and incident pain can be unmanageable. Continuous regional nerve blocks have a definite role in controlling such intractable pain. We describe two such cases where severe pain was adequately relieved in the acute phase. Continuous femoral nerve block was used as an efficient, cheap and safe method of pain relief for two of our patients with pathological fracture femur. This method was proved to be quite efficient in decreasing the fracture-related pain and improving the level of well being.

    2015-01-01

    Purpose/Objective: New national guidelines (GL) for radiotherapy (RT) of head and neck cancer (HNC) were implemented at the beginning of 2013. One purpose of the new GL was to nationally standardise the expansion from GTV to high risk CTV (CTV1). This standardisation has resulted in change...... of volume of CTV1 for most institutions which previously used different margins. Change in CTV1 volume definition could influence the risk and time evolution of adverse effects e.g. mucositis. This study investigates change in acute response during RT in a centre where GTV to CTV1 margin was increased from...

  8. Tumour lysis syndrome: A rare acute presentation of locally advanced testicular cancer – Case report and review of literature

    Marcus Chow

    2016-01-01

    Full Text Available Tumour lysis syndrome (TLS is a potentially fatal complication of malignancy or its treatment. This uncommon syndrome comprises laboratory findings of hyperuricaemia, hypocalcaemia, hyperkalaemia and hyperphosphataemia. A literature search revealed a total of eight patients, with testicular cancer, who had TLS. All these patients had metastatic disease. We present a unique case of a 47-year-old gentleman we saw in clinic, who presented with a rapidly growing right groin mass and acute breathlessness, and discuss the diagnosis and management of TLS. TLS is extremely rare in testicular cancer but necessitates the awareness of urologists. TLS can occur spontaneously in testicular malignancy. Cell lysis in a rapidly proliferating germ cell tumour is a possible mechanism. The prompt identification and institution of management for TLS is crucial to improve clinical outcomes.

    2014-04-01

    Full Text Available Squamous cell carcinoma of the larynx continues to be the commonest head and neck cancer in many Western countries. The larynx plays a key role for many essential functions, including breathing, voice production, airway protection, and swallowing. The goals of laryngeal cancer treatment are thus to provide best possible oncologic control, while optimizing functional outcomes. In recent decades, the treatment paradigm for advanced laryngeal cancer has shifted from one of primary surgery (total laryngectomy as gold standard, toward non-surgical organ-preserving treatment using radiotherapy or chemoradiotherapy. However, concerns have emerged regarding functional outcomes after chemoradiotherapy, as well as possible decreased overall survival in patients with laryngeal cancer. The purpose of the present review is to review surgical and non-surgical options for treatment of advanced laryngeal cancer, as well as the evidence supporting each of these.

  13. Phase Angle and Handgrip Strength Are Sensitive Early Markers of Energy Intake in Hypophagic, Non-Surgical Patients at Nutritional Risk, with Contraindications to Enteral Nutrition

    Riccardo Caccialanza

    2015-03-01

    Full Text Available The assessment of nutritional intakes during hospitalization is crucial, as it is known that nutritional status tends to worsen during the hospital stay, and this can lead to the negative consequences of malnutrition. International guidelines recommend the use of parenteral nutrition (PN in hypophagic, non-surgical patients at nutritional risk, with contraindications to enteral nutrition. However, to date, there are no published data regarding either energy intake or objective measurements associated with it in this patient population. The aim of the present exploratory methodological study was to evaluate whether phase angle (PhA and handgrip strength normalized for skeletal muscle mass (HG/SMM are sensitive early markers of energy intake in hypophagic, non-surgical patients at nutritional risk, with contraindications to enteral nutrition. We evaluated 30 eligible patients, who were treated with personalized dietary modifications and supplemental PN for at least one week during hospitalization. In a liner regression model adjusted for age, gender, basal protein intake and the basal value of each variable, a trend toward improvement of PhA and preservation of HG/SMM was observed in patients satisfying the estimated calorie requirements (N = 20, while a significant deterioration of these parameters occurred in those who were not able to reach the target (N = 10. The mean adjusted difference and 95% CI were +1.4° (0.5–2.3 (p = 0.005 for PhA and +0.23 (0.20–0.43 (p = 0.033 for HG/SMM. A significant correlation between PhA and HG/SMM variations was also observed (r = 0.56 (95% CI, 0.23–0.77; p = 0.0023. PhA and HG/SMM were able to distinguish between hypophagic, non-surgical patients at nutritional risk who satisfied their estimated caloric requirements and those who did not after a one-week personalized nutritional support. Clinical studies are warranted, in order to verify these preliminary observations and to validate the role of Ph

    Full Text Available There is a lack of suitable in vitro models to evaluate various treatment modalities intending to remove subgingival bacterial biofilm. Consequently, the aims of this in vitro-study were: a to establish a pocket model enabling mechanical removal of biofilm and b to evaluate repeated non-surgical periodontal treatment with respect to biofilm removal and reformation, surface alterations, tooth hard-substance-loss, and attachment of periodontal ligament (PDL fibroblasts.Standardized human dentin specimens were colonized by multi-species biofilms for 3.5 days and subsequently placed into artificially created pockets. Non-surgical periodontal treatment was performed as follows: a hand-instrumentation with curettes (CUR, b ultrasonication (US, c subgingival air-polishing using erythritol (EAP and d subgingival air-polishing using erythritol combined with chlorhexidine digluconate (EAP-CHX. The reduction and recolonization of bacterial counts, surface roughness (Ra and Rz, the caused tooth substance-loss (thickness as well as the attachment of PDL fibroblasts were evaluated and statistically analyzed by means of ANOVA with Post-Hoc LSD.After 5 treatments, bacterial reduction in biofilms was highest when applying EAP-CHX (4 log10. The lowest reduction was found after CUR (2 log10. Additionally, substance-loss was the highest when using CUR (128±40 µm in comparison with US (14±12 µm, EAP (6±7 µm and EAP-CHX (11±10 µm. Surface was roughened when using CUR and US. Surfaces exposed to US and to EAP attracted the highest numbers of PDL fibroblasts.The established biofilm model simulating a periodontal pocket combined with interchangeable placements of test specimens with multi-species biofilms enables the evaluation of different non-surgical treatment modalities on biofilm removal and surface alterations. Compared to hand instrumentation the application of ultrasonication and of air-polishing with erythritol prevents from substance-loss and results

  15. Risk of Severe Acute Exacerbation of Chronic HBV Infection Cancer Patients Who Underwent Chemotherapy and Did Not Receive Anti-Viral Prophylaxis.

    Full Text Available Reactivation of HBV replication with an increase in serum HBV DNA and alanine aminotransferase (ALT activity has been reported in 20-50% of hepatitis B carriers undergoing cytotoxic chemotherapy for cancer treatment. Manifestation of HBV reactivation ranges from asymptomatic self-limiting hepatitis to severe progressive hepatic failure and fatal consequences.To investigate the risk of severe acute exacerbation of chronic HBV infection in HBsAg-positive cancer patients with solid tumors or hematological malignancies who underwent chemotherapy without antiviral prophylaxis.A retrospective review of charts was conducted for HBsAg-positive cancer patients in our institution who underwent chemotherapy and did not receive anti-viral prophylaxis between the periods of July 2007 to January 2013. We investigate the incidence of severe acute exacerbation of chronic HBV infection if these patients with a variety of solid tumors and hematological malignancies.A total of 156 patients (hematological malignancies: 16; solid tumors: 140 were included. The incidence of severe acute HBV exacerbation in the patients with hematological malignancy was higher than that in solid tumors (25.0% [4/16] vs 4.3% [6/140]; P = 0.005. Additionally, patients receiving rituximab-based chemotherapy had higher acute exacerbation rate than those with non-rituximab-based chemotherapy (40.0% vs 4.1%, P = 0.001. Among the patients with solid tumors, the incidences of severe acute exacerbation of chronic HBV in hepatocellular carcinoma, colorectal cancer, lung cancer, breast cancer, gynecological cancer, urological tract cancer, head/neck cancer and other solid malignancies were 2.3%, 4.0%, 7.1%, 9.0%, 16.7%, 6.7%, 0% and 0%, respectively.Severe acute exacerbation of chronic HBV infection may occur in HBsAg-positive patients with a variety of solid tumors who received chemotherapy without adequate anti-viral prophylaxis.

    1997-08-01

    Between 1987 and 1995, 120 patients with rectal cancer (73 patients with primary tumor, 47 with recurrent disease) received chemoradiation for rectal cancer. Fifty-six patients received preoperative chemoradiation, 64 patients were treated postoperatively. Radiation was given by 4-field box technique with 6 to 10 MV-photons. Daily fraction size was 1.8 Gy, total dose 50.4 Gy (range: 41,4 to 56 Gy) {+-} 5.4 Gy (range: 3.6 to 19.8 Gy) local boost in selected cases, specified to the ICRU reference point. During the first and fifth week of radiation 5-FU at a dose of 1000 m{sup 2}/d for 120 hours was administered by continuous infusion. Toxicity was recorded following (modified) WHO-criteria. Results: Acute grade 3 toxicity occurred mainly as diarrhea (33%), perineal skin reaction (37%), and leukopenia (10%). Extension of the treatment volume including paraaortic lymph nodes (L3) led to a significant increase of grade 3-diarrhea (68% vs. 25%, p = 0.0003) and grade 3-leukopenia (18% vs. 8%, p = 0.03). After abdominoperineal resection less patients suffered from grade 3-diarrhea (8% vs. 47% after sphincter preserving procedures, p = 0.0006), whereas severe perineal erythema occurred more frequently (56% vs. 29%, p = 0.02). Women had significantly more toxic side effects (grade 3-diarrhea: 39% vs. 16% in men, p = 0,04; grade 2 to 3-nausea/emesis: 21% vs 8% in men, p = 0.018; grade 2 to 3-leukopenia 53% vs. 31% in men, p = 0.02). After preoperative chemoradiation a significant reduction of grade 3-diarrhea (11% vs 29%, p = 0.03) and grade 3-erythema (16% vs. 41%, p = 0.04) was noted.

  17. Intensity-Modulated Radiotherapy as Primary Therapy for Prostate Cancer: Report on Acute Toxicity After Dose Escalation With Simultaneous Integrated Boost to Intraprostatic Lesion

    Purpose: To report on the acute toxicity of a third escalation level using intensity-modulated radiotherapy for prostate cancer (PCa) and the acute toxicity resulting from delivery of a simultaneous integrated boost (SIB) to an intraprostatic lesion (IPL) detected on magnetic resonance imaging (MRI), with or without spectroscopy. Methods and Materials: Between January 2002 and March 2007, we treated 230 patients with intensity-modulated radiotherapy to a third escalation level as primary therapy for prostate cancer. If an IPL (defined by MRI or MRI plus spectroscopy) was present, a SIB was delivered to the IPL. To report on acute toxicity, patients were seen weekly during treatment and 1 and 3 months after treatment. Toxicity was scored using the Radiation Therapy Oncology Group toxicity scale, supplemented by an in-house-developed scoring system. Results: The median dose to the planning target volume was 78 Gy. An IPL was found in 118 patients. The median dose to the MRI-detected IPL and MRI plus spectroscopy-detected IPL was 81 Gy and 82 Gy, respectively. No Grade 3 or 4 acute gastrointestinal toxicity developed. Grade 2 acute gastrointestinal toxicity was present in 26 patients (11%). Grade 3 genitourinary toxicity was present in 15 patients (7%), and 95 patients developed Grade 2 acute genitourinary toxicity (41%). No statistically significant increase was found in Grade 2-3 acute gastrointestinal or genitourinary toxicity after a SIB to an IPL. Conclusion: The results of our study have shown that treatment-induced acute toxicity remains low when intensity-modulated radiotherapy to 80 Gy as primary therapy for prostate cancer is used. In addition, a SIB to an IPL did not increase the severity or incidence of acute toxicity

  18. A biologically competitive 21 days hypofractionation scheme with weekly concomitant boost in breast cancer radiotherapy feasibility acute sub-acute and short term late effects

    Radiation therapy after lumpectomy is a standard part of breast conserving therapy for invasive breast carcinoma. The most frequently used schedule worldwide is 60 Gy in 30 fractions in 6 weeks, a time commitment that sporadically may dissuade some otherwise eligible women from undertaking treatment. The purpose and primary endpoint of this perspective study is to evaluate feasibility and short-term late toxicity in a hypofractionated whole breast irradiation schedule. Between February and October 2008 we treated 65 consecutive patients with operable invasive early-stage breast cancer with a hypofractionated schedule of external beam radiation therapy. All patients were assigned to 39 Gy in 13 fractions in 3 weeks to the whole breast plus a concomitant weekly boost dose to the lumpectomy cavity of 3 Gy in 3 fractions. All the patients had achieved a median follow up of 24 months (range 21-29 months). At the end of treatment 52% presented grade 0 acute toxicity 39% had grade 1 and 9% had grade 2. At 6 months with all the patients assessed there were 34% case of grade 1 subacute toxicity and 6% of grade 2. At 12 months 43% and 3% of patients presented with clinical grade 1 and grade 2 fibrosis respectively and 5% presented grade 1 hyperpigmentation. The remaining patients were free of side effects. At 24 months, with 56 assessed, just 2 patients (3%) showed grade 2 of late fibrosis. The clinical results observed showed a reasonably good feasibility of the accelerated hypofractionated schedule in terms of acute, subacute and short-term late toxicity. This useful 13 fractions with a concomitant boost schedule seems, in selected patients, a biologically acceptable alternative to the traditional 30 days regime

  19. Acute small bowel toxicity and preoperative chemoradiotherapy for rectal cancer: Investigating dose-volume relationships and role for inverse planning

    Purpose: The relationship between volume of irradiated small bowel (VSB) and acute toxicity in rectal cancer radiotherapy is poorly quantified, particularly in patients receiving concurrent preoperative chemoradiotherapy. Using treatment planning data, we studied a series of such patients. Methods and Materials: Details of 41 patients with locally advanced rectal cancer were reviewed. All received 45 Gy in 25 fractions over 5 weeks, 3-4 fields three-dimensional conformal radiotherapy with daily 5-fluorouracil and folinic acid during Weeks 1 and 5. Toxicity was assessed prospectively in a weekly clinic. Using computed tomography planning software, the VSB was determined at 5 Gy dose intervals (V5, V1, etc.). Eight patients with maximal VSB had dosimetry and radiobiological modeling outcomes compared between inverse and conformal three-dimensional planning. Results: VSB correlated strongly with diarrheal severity at every dose level (p 5 and V15. Conclusions: A strong dose-volume relationship exists between VSB and acute diarrhea at all dose levels during preoperative chemoradiotherapy. Our constructed model may be useful in predicting toxicity, and this has been derived without the confounding influence of surgical excision on bowel function. Inverse planning can reduce calculated dose to small bowel and late NTCP, and its clinical role warrants further investigation

  20. Low acute toxicity of radiotherapy and radiochemotherapy in patients with cancer of the anal canal and HIV-infection

    Although not an AIDS-defining malignancy, anal cancer is an evolving problem in HIV-infected patients. Treatment-tolerance to radiotherapy as well as to chemotherapy is supposed to be reduced in patients with HIV-infection. From January 1995 to January 1997, four patients with epidermoid cancer of the anal canal and a long history of HIV-infection but without symptoms of AIDS or repeated severe infections were treated with radiotherapy (n=1) or radiochemotherapy (n=3). External beam radiotherapy with 45 Gy to the tumor and pelvic as well as inguinal lymphatic drainage was administered. In tumors larger than T2 N0 lesions an additional boost of 9 Gy was given. Chemotherapy consisted of 5-fluorouracil 1000 mg/m2/24 h, d 1-4 two cycles and Mitomycin C either 1 x 15 mg/m2, d 1 in the first, or 2 x 10 mg/m2, d 1, in the first and fifth week of radiotherapy. Acute reactions were mild to moderate in all patients and all but one treatment could be given as scheduled (1 patient with a delay of 4 days). No excessive acute reactions were seen. Because of the short follow-up, late reactions and local control are not yet evaluable. (orig.)

  1. Development of a Set of Nomograms to Predict Acute Lower Gastrointestinal Toxicity for Prostate Cancer 3D-CRT

    Purpose: To predict acute Radiation Therapy Oncology Group (RTOG)/European Organization for Research and Treatment of Cancer (EORTC) and Subjective Objective Signs Management and Analysis/Late Effect of Normal Tissue (SOMA/LENT) toxicities of the lower gastrointestinal (LGI) syndrome in patients with prostate cancer undergoing three-dimensional conformal radiotherapy using a tool (nomogram) that takes into account clinical and dosimetric variables that proved to be significant in the Italian Association for Radiation Oncology (AIRO) Group on Prostate Cancer (AIROPROS) 0102 trial. Methods and Materials: Acute rectal toxicity was scored in 1,132 patients by using both the RTOG/EORTC scoring system and a 10-item self-assessed questionnaire. Correlation between clinical variables/dose-volume histogram constraints and rectal toxicity was investigated by means of multivariate logistic analyses. Multivariate logistic analyses results were used to create nomograms predicting the symptoms of acute LGI syndrome. Results: Mean rectal dose was a strong predictor of Grade 2-3 RTOG/EORTC acute LGI toxicity (p 0.0004; odds ratio (OR) = 1.035), together with hemorrhoids (p = 0.02; OR 1.51), use of anticoagulants/antiaggregants (p = 0.02; OR = 0.63), and androgen deprivation (AD) (p = 0.04; OR = 0.65). Diabetes (p = 0.34; OR 1.28) and pelvic node irradiation (p = 0.11; OR = 1.56) were significant variables to adjust toxicity prediction. Bleeding was related to hemorrhoids (p = 0.02; OR = 173), AD (p = 0.17; OR = 0.67), and mean rectal dose (p 0.009; OR = 1.024). Stool frequency was related to seminal vesicle irradiation (p = 0.07; OR = 6.46), AD administered for more than 3 months (p = 0.002; OR = 0.32), and the percent volume of rectum receiving more than 60 Gy (V60Gy) V60 (p = 0.02; OR = 1.02). Severe fecal incontinence depended on seminal vesicle irradiation (p = 0.14; OR = 4.5) and V70 (p = 0.033; OR 1.029). Conclusions: To the best of our knowledge, this work presents the

    There have been a growing numbers of patients diagnosed with malignancy and coronary artery disease simultaneously or serially. In the era of percutaneous coronary intervention (PCI), stent thrombosis has been a rare but challenging problem. Recently, we experienced two unique cases of acute stent thrombosis in patients with malignancy. The first case showed acute and subacute stent thrombosis after PCI. The second case revealed simultaneous thromboses in stent and non-treated native coronary...

  3. Non-surgical treatment for localized gastric mucosa-associated lymphoid tissue (MALT) lymphoma. Interium analysis of a multicenter prospective study in Japan

    Although eradication of Helicobacter pylori and radiation therapy (RT) have curative potential for gastric mucosa-associated lymphoid tissue (MALT) lymphoma, no prospective study has yet been reported. This prospective study evaluated the efficacy and safety of this non-surgical treatment for localized gastric MALT lymphoma. Among the 115 eligible patients, 89 (77.3%) achieved remission with eradication therapy. Twenty five (21.7%) patients received RT as additional treatment for residual tumor and 22 (88%) achieved complete remission. No serious adverse events, such as hemorrhage or perforation of the stomach, were observed. This organ-preserving treatment for localized gastric MALT lymphoma is safe and effective and has the potential to become the standard treatment for this disease, although long-term follow up is necessary.

  4. Predictive value of sequential 18F-FDG PET/CT scan in concurrent chemoradiotherapy of non-surgical esophageal carcinoma

    Objective: To investigate the metabolic changes during the concurrent chemoradiotherapy (CCRT) of non-surgical esophageal squamous cell cancer (ESCC) and to explore the predictive value of sequential 18F-FDG PET/CT scan in CCRT. Methods: From May 2009 to October 2011, 28 patients with pathologically confirmed ESCC were prospectively enrolled into this study. All patients received definitive treatment with CCRT. 18F-FDG PET/CT scans were performed at the following 4 time points: before therapy, at the time when radiation dose reached 50 Gy and 60 Gy, and one month after treatment completion. SUVmax of the 4 time points were recorded as SUVmax1-4. The volume of the area with SUV greater than 40% SUVmax in primary tumor and adjacent lymph node was summed and named as MTV. The starting point of all survival data was from primary disease documentation. All patients had regular follow-up (median time: 18.5 months) to record the disease status, including progress free survival (PFS), recurrence free survival (RFS) and overall survival (OS). Patients were divided into different groups according to the following status: progress free or progress, no recurrence or recurrence and death or living. The Mann-Whitney u test was used to compare SUVmax and the rate of △SUVmax in different groups. The AUC of ROC curve was calculated to find the optimal threshold of MTV. Kaplan-Meier and Cox regression were utilized to analyze the differentiation of survival. Results: Among the 28 patients, 19 showed disease progression, 17 showed recurrence and 15 died during follow-up.In the groups of recurrence or no recurrence, there were statistical differences for SUVmax2 and SUVmax3, (SUVmax2: 7.4±3.3 vs 4.8±2.5; SUVmax3: 5.5±2.1 vs 3.8±2.1; u=46 and 47, both P<0.05). As for SUVmax4, statistical differences could be found at every survival group (progress vs progress free: 5.3±3.9 vs 2.4± 1.7; recurrence vs no recurrence: 5.6±4.0 vs 2.4± 1.5; death vs living: 5.8±4.2 vs 2.6± 1.5; u

    Purpose: Research on patient-reported outcomes (PROs) in rectal cancer is limited. We examined whether dose-volume parameters of the small bowel and large bowel were associated with patient-reported gastrointestinal (GI) symptoms during 5-fluorouracil (5-FU)-based chemoradiation treatment for rectal cancer. Methods and Materials: 66 patients treated at the Brigham and Women's Hospital or Massachusetts General Hospital between 2006 and 2008 were included. Weekly during treatment, patients completed a questionnaire assessing severity of diarrhea, urgency, pain, cramping, mucus, and tenesmus. The association between dosimetric parameters and changes in overall GI symptoms from baseline through treatment was examined by using Spearman's correlation. Potential associations between these parameters and individual GI symptoms were also explored. Results: The amount of small bowel receiving at least 15 Gy (V15) was significantly associated with acute symptoms (p = 0.01), and other dosimetric parameters ranging from V5 to V45 also trended toward association. For the large bowel, correlations between dosimetric parameters and overall GI symptoms at the higher dose levels from V25 to V45 did not reach statistical significance (p = 0.1), and a significant association was seen with rectal pain from V15 to V45 (p < 0.01). Other individual symptoms did not correlate with small bowel or large bowel dosimetric parameters. Conclusions: The results of this study using PROs are consistent with prior studies with physician-assessed acute toxicity, and they identify small bowel V15 as an important predictor of acute GI symptoms during 5-FU-based chemoradiation treatment. A better understanding of the relationship between radiation dosimetric parameters and PROs may allow physicians to improve radiation planning to optimize patient outcomes.

    We wanted to investigate the relationship between the magnetic resonance (MR) findings and the clinical outcome after treatment with non-surgical transforaminal epidural steroid injections (ESI) for lumbar herniated intervertebral disc (HIVD) patients. Transforaminal ESI were performed in 91 patients (50 males and 41 females, age range: 13 78 yrs) because of lumbosacral HIVD from March 2001 to August 2002. Sixty eight patients whose MRIs and clinical follow-ups were available were included in this study. The medical charts were retrospectively reviewed and the patients were divided into two groups; the successful (responders, n = 41) and unsatisfactory (non-responders, n = 27) outcome groups. A successful outcome required a patient satisfaction score greater than two and a pain reduction score greater than 50%. The MR findings were retrospectively analyzed and compared between the two groups with regard to the type (protrusion, extrusion or sequestration), hydration (the T2 signal intensity), location (central, right/left central, subarticular, foraminal or extraforaminal), and size (volume) of the HIVD, the grade of nerve root compression (grade 1 abutment, 2 displacement and 3 entrapment), and an association with spinal stenosis. There was no significant difference between the responders and nonresponders in terms of the type, hydration and size of the HIVD, or an association with spinal stenosis (p > 0.05). However, the location of the HIVD and the grade of nerve root compression were different between the two groups (p < 0.05). MRI could play an important role in predicting the clinical outcome of non-surgical transforaminal ESI treatment for patients with lumbar HIVD.

    Full Text Available Background: Recent epidemiological studies have shown that periodontal infection is a risk factor for a number of systemic diseases and conditions. In addition to the conventional risk factors, chronic infection and the subsequent generation of a systemic inflammatory response may be associated with this increased risk. Aims: This study was conducted to determine whether the presence of chronic periodontitis and subsequent non-surgical periodontal therapy could influence the serum levels of interleukin-6 and C-reactive protein (CRP in patients with severe chronic generalized periodontitis. Settings and Design: Participants were selected from subjects who attended the Department of Periodontics and Oral Implantololgy, Government Dental College, Thiruvananthapuram. Materials and Methods: Sera were obtained from 25 patients with periodontitis for baseline examination and reassessment after completion of treatment. As a control, sera were also obtained from 20 subjects without periodontitis. Interleukin-6 was determined by sensitive enzyme-linked immunosorbent assay, and high-sensitivity CRP (hsCRP was measured using latex turbidometric immunoassay. Statistical Analysis: Data were analyzed using computer software, Statistical Package for Social Sciences (SPSS version 10. Results: The level of interleukin-6 and hsCRP in the sera of periodontitis patients was seen to be higher than those of healthy controls. Interleukin-6 level tended to decrease with improvement of the periodontal condition following treatment and approached that of control subjects, and this decline was statistically significant. The hsCRP levels also showed a decreasing trend following periodontal treatment. Conclusions: In this study, we were able to show that periodontal disease significantly affects the serum levels of systemic inflammatory markers and that non-surgical periodontal therapy could bring about a decrease in the levels of these inflammatory markers.

  9. Factors influencing incidence of acute grade 2 morbidity in conformal and standard radiation treatment of prostate cancer

    Purpose: The fundament hypothesis of conformal radiation therapy is that tumor control can be increased by using conformal treatment techniques that allow a higher tumor dose while maintaining an acceptable level of complications. To test this hypothesis, it is necessary first to estimate the incidence of morbidity for both standard and conformal fields. In this study, we examine factors that influence the incidence of acute grade 2 morbidity in patients treated with conformal and standard radiation treatment for prostate cancer. Methods and Materials: Two hundred and forty-seven consecutive patients treated with conformal technique are combined with and compared to 162 consecutive patients treated with standard techniques. The conformal technique includes special immobilization by a cast, careful identification of the target volume in three dimensions, localization of the inferior border of the prostate using the retrograde urethrogram, and individually shaped portals that conform to the Planning Target Volume (PTV). Univariate analysis compares differences in the incidence of RTOG-EORTC grade two acute morbidity by technique, T stage, age, irradiated volume, and dose. Multivariate logistic regression includes these same variables. Results: In nearly all categories, the conformal treatment group experienced significantly fewer acute grade 2 complications than the standard treatment group. Only volume (prostate ± whole pelvis) and technique (conformal vs. standard) were significantly related to incidence of morbidity on multivariate analysis. When dose is treated as a continuous variable (rather than being dichotomized into two levels), a trend is observed on multivariate analysis, but it does not reach significant levels. The incidence of acute grade 2 morbidity in patients 65 years or older is significantly reduced by use of the conformal technique. Conclusion: The conformal technique is associated with fewer grade 2 acute toxicities for all patients. This

  10. The Impact of Pretreatment Prostate Volume on Severe Acute Genitourinary Toxicity in Prostate Cancer Patients Treated With Intensity-Modulated Radiation Therapy

    Purpose: To assess the impact of pretreatment prostate volume on the development of severe acute genitourinary toxicity in patients undergoing intensity-modulated radiation therapy (IMRT) for prostate cancer. Methods and Materials: Between 2004 and 2007, a consecutive sample of 214 patients who underwent IMRT (75.6 Gy) for prostate cancer at two referral centers was analyzed. Prostate volumes were obtained from computed tomography scans taken during treatment simulation. Genitourinary toxicity was defined using the National Cancer Institute Common Terminology Criteria for Adverse Events Version 3.0 guidelines. Acute toxicity was defined as any toxicity originating within 90 days of the completion of radiation therapy. Patients were characterized as having a small or large prostate depending on whether their prostate volume was less than or greater than 50 cm3, respectively. Genitourinary toxicity was compared in these groups using the chi-square or Fisher's exact test, as appropriate. Bivariate and multivariate logistic regression analysis was performed to further assess the impact of prostate volume on severe (Grade 3) acute genitourinary toxicity. Results: Patients with large prostates (>50 cm3) had a higher rate of acute Grade 3 genitourinary toxicity (p = .02). Prostate volume was predictive of the likelihood of developing acute Grade 3 genitourinary toxicity on bivariate (p = .004) and multivariate (p = .006) logistic regression. Every 27.0 cm3 increase in prostate volume doubled the likelihood of acute Grade 3 genitourinary toxicity. Conclusions: Patients with larger prostates are at higher risk for the development of severe acute genitourinary toxicity when treated with IMRT for prostate cancer.

    2012-08-01

    Purpose: One of the worst radiation-induced acute effects in treating head-and-neck (HN) cancer is grade 3 or higher acute (oral and pharyngeal) mucosal toxicity (AMT), caused by the killing/depletion of mucosa cells. Here we aim to testing a predictive model of the AMT in HN cancer patients receiving different radiotherapy schedules. Methods and Materials: Various radiotherapeutic schedules have been reviewed and classified as tolerable or intolerable based on AMT severity. A modified normal tissue complication probability (NTCP) model has been investigated to describe AMT data in radiotherapy regimens, both conventional and altered in dose and overall treatment time (OTT). We tested the hypothesis that such a model could also be applied to identify intolerable treatment and to predict AMT. This AMT NTCP model has been compared with other published predictive models to identify schedules that are either tolerable or intolerable. The area under the curve (AUC) was calculated for all models, assuming treatment tolerance as the gold standard. The correlation between AMT and the predicted toxicity rate was assessed by a Pearson correlation test. Results: The AMT NTCP model was able to distinguish between acceptable and intolerable schedules among the data available for the study (AUC = 0.84, 95% confidence interval = 0.75-0.92). In the equivalent dose at 2 Gy/fraction (EQD2) vs OTT space, the proposed model shows a trend similar to that of models proposed by other authors, but was superior in detecting some intolerable schedules. Moreover, it was able to predict the incidence of {>=}G3 AMT. Conclusion: The proposed model is able to predict {>=}G3 AMT after HN cancer radiotherapy, and could be useful for designing altered/hypofractionated schedules to reduce the incidence of AMT.

    From September 1997 through October 1998, 30 patients with stage II/III rectal cancer underwent postoperative radiochemotherapy at our department. All patients had undergone curative (R0) resection and received 50.4 Gy to the pelvis with a 3-field technique using a belly board followed by a boost of 5.4 Gy to the presacral space in conventional fractionation with 1.8 Gy per fraction. 5-FU chemotherapy was administered as 120-hours continuous infusion in the first and fifth radiation week via a central venous catheter in a daily dosage of 1000 mg/m{sup 2}. All patients were offered to participate in a phase-II study using additional amifostine. Fifteen patients participated and received 500 mg amifostine daily on chemotherapy days (days 1 to 5 and 29 to 33) immediately prior to the daily radiation fraction. Fifteen patients did not participate and served as non-randomized control. The study was approved by the ethical committee of the Martin-Luter-University and informed consent was obtained from all patients. Results: The distribution of patients' characteristics and prognostic parameters was comparable in both groups. Side effects of amifostine were mild and included hypotension (53% grade I, 7% grade II) and nausea (47% grade I, 13% grade II). Antiemetics were not routinely used. All patients completed radiochemotherapy plus amifostine without unplanned breaks or dose reductions. One patients developed a cerebral infraction which was considered to be not related to the use of amifostine. As compared to the non-randomized control group, patients with additional amifostine had less acute skin and bowel toxicity (maximum erythema score 1.47{+-}0.64 without vs 0.87{+-}0.52 with amifostine, p=0.009 and maximum diarrhea score 1.07{+-}1.03 vs 0.40{+-}0.63, p=0.044). Oral 5-FU-related mucositis and hematological toxicity were not significantly different. (orig.) [German] Zwischen September 1997 und Oktober 1998 wurden 15 Patienten mit postoperativer

    Full Text Available Abstract Backgraund Acute-phase response proteins (APRP, cytokines and hormones have been claimed to be an independent prognostic factor of malignancies, however the basis for their association with prognosis remains unexplained. We suggest that in colon malignancies, as similar to pancreatic and lung cancers, changes in APRP are associated with angiogenesis. Methods C-reactive protein (CRP, albumin, IL-1α, IL-1β, IL-6, IL-8, IL-10, TNF-α, midkine, VEGF-A, VEGF-C, leptin, adiponectin, and ghrelin serum levels are studied in 126 colon cancer patients and 36 healthy subjects. Results We found statistically significant difference and correlations between two groups. We found significantly higher serum CRP, IL-1α, IL-1β, IL-6, IL-8, IL-10, TNF-α, VEGF-A, VEGF-C and leptin concentrations in patients relative to controls (p Conclusions Cachexia in patients with colon cancers is associated with changes in APRP, cytokines and hormone concentrations. These biomarkers and cachexia together have a direct relationship with accelerated angiogenesis. This may lead to a connection between the outcomes in malignancies and the biomarkers.

  14. Risk of acute exacerbation of interstitial pneumonia after pulmonary resection for lung cancer in patients with idiopathic pulmonary fibrosis based on preoperative high-resolution computed tomography

    In patients with lung cancer accompanied by idiopathic pulmonary fibrosis (IPF), acute exacerbation of the IPF often occurs after pulmonary resection; however, few studies have been done to identify its preexisting risk factors. We analyzed the high-resolution computed tomography (HRCT) findings of IPF to identify the radiological characteristics of IPF susceptible to acute exacerbation after lung cancer surgery. We reviewed retrospectively 28 lung cancer patients with IPF who underwent pulmonary resection. Clinical data, respiratory function, HRCT findings, and historical features were compared between the acute exacerbation (n=9) and nonexacerbation (n=19) groups. The classification of radiological findings of IPF on HRCT was done using a scoring system of seven factors related to the interstitial shadow, including fibrosis, ground-glass opacity, and low-attenuation area. There were no significant differences in clinical background, respiratory function, composite physiologic index, or pathological features between the groups; however, the degree of fibrosis on preoperative HRCT was significantly higher in the exacerbation group (P<0.003). The fibrosis score was higher on the opposite side to the lung cancer in the exacerbation group (P<0.05). Although it is difficult to predict postoperative acute IPF exacerbation, the degree and laterality of co-existing fibrosis seem to be predictors. (author)

    A clinical case with acute radiation reaction of the left breast after organ-preserving surgery with 10 Gy IORT (24.8 Gy) conventional radiation therapy has been presented. Comprehensive MRI examination showed signs of radiation- induced damage to skin, soft tissues and vessels of the residual breast.

  19. Acute Toxicity Profile and Compliance to Accelerated Radiotherapy Plus Carbogen and Nicotinamide for Clinical Stage T2–4 Laryngeal Cancer: Results of a Phase III Randomized Trial

    Purpose: To report the acute toxicity profile and compliance from a randomized Phase III trial comparing accelerated radiotherapy (AR) with accelerated radiotherapy plus carbogen and nicotinamide (ARCON) in laryngeal cancer. Methods and Materials: From April 2001 to February 2008, 345 patients with cT2–4 squamous cell laryngeal cancer were randomized to AR (n = 174) and ARCON (n = 171). Acute toxicity was scored weekly until Week 8 and every 2–4 weeks thereafter. Compliance to carbogen and nicotinamide was reported. Results: Between both treatment arms (AR vs. ARCON) no statistically significant difference was observed for incidence of acute skin reactions (moist desquamation: 56% vs. 58%, p = 0.80), acute mucosal reactions (confluent mucositis: 79% vs. 85%, p = 0.14), and symptoms related to acute mucositis (severe pain on swallowing: 53% vs. 58%, p = 0.37; nasogastric tube feeding: 28% vs. 28%, p = 0.98; narcotic medicines required: 58% vs. 58%, p = 0.97). There was a statistically significant difference in median duration of confluent mucositis in favor of AR (2.0 vs 3.0 weeks, p = 0.01). There was full compliance with carbogen breathing and nicotinamide in 86% and 80% of the patients, with discontinuation in 6% and 12%, respectively. Adjustment of antiemesis prophylaxis was needed in 42% of patients. Conclusion: With the exception of a slight increase in median duration of acute confluent mucositis, the present data reveal a similar acute toxicity profile between both regimens and a good compliance with ARCON for clinical stage T2–4 laryngeal cancers. Treatment outcome and late morbidity will determine the real therapeutic benefit.

    Acute respiratory failure (ARF) is the leading reason for intensive care unit (ICU) admission in patients with cancer. The aim of this study was to identify early predictors of death in patients with cancer admitted to the ICU for ARF who were not intubated at admission. We conducted analysis of a prospective randomized controlled trial including 219 patients with cancer with ARF in which day-28 mortality was a secondary endpoint. Mortality at day 28 was 31.1%. By multivariate analysis, independent predictors of day-28 mortality were: age (odds ratio [OR] 1.30/10 years, 95% confidence interval [CI] [1.01-1.68], p = 0.04), more than one line of chemotherapy (OR 2.14, 95% CI [1.08-4.21], p = 0.03), time between respiratory symptoms onset and ICU admission > 2 days (OR 2.50, 95% CI [1.25-5.02], p = 0.01), oxygen flow at admission (OR 1.07/L, 95% CI [1.00-1.14], p = 0.04) and extra-respiratory symptoms (OR 2.84, 95%CI [1.30-6.21], p = 0.01). After adjustment for the logistic organ dysfunction (LOD) score at admission, only time between respiratory symptoms onset and ICU admission > 2 days and LOD score were independently associated with day-28 mortality. Determinants of death include both factors non-amenable to change, and delay in ARF management. These results suggest that early intensive care management of patients with cancer with ARF may translate to better survival. PMID:23185988

    Renal infarction is a rare cause of acute kidney injury which could lead to permanent loss of renal function. A prompt diagnosis is necessary in order to achieve a successful revascularization of the occluded artery. Given the rarity of the disease and the paucity of the reported cases in the previous literature a high index of suspicion must be maintained not only in the classical cardiac sources of systemic emboli (atrial fibrillation, dilated cardiomyopathy, or endocarditis), but also in the situations when a hypercoagulable state is presumed. The unspecific presenting symptoms often mask the true etiology of the patient's complaints. We present here a rare case of renal infarction that occurred in the setting of a hypercoagulable state, in a female patient with a history of breast cancer and documented hepatic metastases.

  4. In vitro radiosensitivity of primary human fibroblasts. Lack of correlation with acute radiation toxicity in patients with head and neck cancer

    Background and purpose: There is a considerable hope among clinicians and radiobiologists to detect genetically radiosensitive patients prior to radiotherapy. A predictive assay would enable adjustment of the total irradiation dose to the individual at a constant risk of normal tissue complications. In this prospective study, the clonogenic survival assay for primary human fibroblasts to determine radiosensitivity in vitro was evaluated and then correlated with clinically observed acute radiation reactions. Materials and methods: One hundred twenty-five independent survival experiments with primary fibroblasts derived from 63 biopsies from 55 cancer and non-cancer patients were performed. Results: A wide variation of cell survival between biopsies was detected. Statistical analysis revealed a highly significantly larger interindividual than intraindividual variation of SF2 values. However, a considerable scatter of SF2 values in repeated experiments was observed in individual cases. Age, gender, disease status (cancer patient, non-cancer patient) and origin of fibroblasts (skin, periodontal tissue) were demonstrated not to be statistically significant confounding factors on the intrinsic radiosensitivity in vitro. In a prospective study, no correlation of the SF2 and acute reactions in 25 patients with head and neck cancer treated with a primary accelerated radiochemotherapy was detected. Conclusion: Our data show that the clonogenic assay is able to distinguish between intrinsic radiosensitivities of primary human fibroblasts if a statistical approach is used but does not predict acute radiation toxicity

  5. Use of Axillary Deodorant and Effect on Acute Skin Toxicity During Radiotherapy for Breast Cancer: A Prospective Randomized Noninferiority Trial

    Purpose: To prospectively determine the effect of deodorant use on acute skin toxicity and quality of life during breast radiotherapy (RT). Methods and Materials: Before breast RT, 84 patients were randomly assigned to the deodorant group (n = 40) or the no-deodorant group (n = 44). The patients were stratified by axillary RT and previous chemotherapy. Toxicity evaluations were always performed by the principal investigator, who was unaware of the group assignment, at the end of RT and 2 weeks after completion using the Radiation Therapy Oncology Group acute skin toxicity criteria. Symptoms of acute skin toxicity (i.e., discomfort, pain, pruritus, sweating) and quality of life were self-evaluated. For each criterion, the point estimate of rate difference with the 95% one-sided upper confidence limit was computed. To claim noninferiority owing to deodorant use, the 95% one-sided upper confidence limit had to be lower than the noninferiority margin, fixed to 12.8%. Results: In the deodorant vs. no-deodorant groups, Grade 2 axillary radiodermatitis occurred in 23% vs. 30%, respectively, satisfying the statistical criteria for noninferiority (p = .019). Grade 2 breast radiodermatitis occurred in 30% vs. 34% of the deodorant vs. no-deodorant groups, respectively, also satisfying the statistical criteria for noninferiority (p = .049). Similar results were observed for the self-reported evaluations. The deodorant group reported less sweating (18% vs. 39%, p = .032). No Grade 3 or 4 radiodermatitis was observed. Conclusion: According to our noninferiority margin definition, the occurrence of skin toxicity and its related symptoms were statistically equivalent in both groups. No evidence was found to prohibit deodorant use (notwithstanding the use of an antiperspirant with aluminum) during RT for breast cancer.

    Background Resistance exercise is emerging as a potential adjunct therapy to aid in the management of breast cancer-related lymphedema (BCRL). However, the mechanisms underlying the relationships between the acute and long-term benefits of resistance exercise on BCRL are not well understood. Purpose To examine the acute inflammatory response to upper-body resistance exercise in women with BCRL and to compare these effects between resistance exercises involving low, moderate, and high loads. The impact on lymphedema status and associated symptoms was also compared. Methods A total of 21 women, 62 ± 10 years old, with BCRL participated in the study. Participants completed low-load (15-20 repetition maximum [RM]), moderate-load (10-12 RM), and high-load (6-8 RM) exercise sessions consisting of 3 sets of 6 upper-body resistance exercises. Sessions were completed in a randomized order separated by a 7- to 10-day wash-out period. Venous blood samples were obtained to assess markers of exercise-induced muscle damage and inflammation. Lymphedema status was assessed using bioimpedance spectroscopy and arm circumferences, and associated symptoms were assessed using Visual Analogue Scales for pain, heaviness, and tightness. Measurements were conducted before and 24 hours after the exercise sessions. Results No significant changes in creatine kinase, C-reactive protein, interleukin-6, and tumor necrosis factor-α were observed following the 3 resistance exercise sessions. There were no significant changes in arm swelling or symptom severity scores across the 3 resistance exercise conditions. Conclusions The magnitude of acute exercise-induced inflammation following upper-body resistance exercise in women with BCRL does not vary between resistance exercise loads. PMID:26582633

    Full Text Available OBJECTIVE: Patients with malignancies may develop autoimmune and rheumatic manifestations as a result of generation of autoantibodies, paraneoplastic syndromes, direct invasion of joints and muscles by the tumour cells, or combination chemotherapy. We present a case with prostate cancer and acute kidney injury (AKI mimicking rapidly progressive glomerulonephritis with a positive test result for anti-double-stranded deoxyribonucleic acid antibodies (Anti-dsDNA ab. CASE PRESENTATION: The 78-year-old male patient applied to our center with the complaint of generalized bone pain since approximately two months, and rapid onset of weakness, oliguria and dysuria for three days. He had been diagnosed metastatic prostate cancer (PC for two years and at the time of application had received high dose of naproxen sodium because of severe bone pain for 5 days. Serum creatinine level was elevated on admission (2.4 mg/dl. Urinalysis revealed microscopic hematuria, granular casts and proteinuria of 1.2 gr/day. Immunologic tests including Anti-dsDNA antibody were done regarding acute nephritic syndrome. The subject was positive for Anti-dsDNA ab with a value of 96 IU/ml (normal, <10 IU/ml. Renal biopsy was planned but the patient refused the procedure. After 6 days of oliguric period, his clinical condition and renal functions returned almost to normal with supportive care within 12 days. CONCLUSION: Malignant diseases may be a trigger for either the generation of some autoantibodies. Attention must be paid when interpreting the Anti-dsDNA positivity in malignant patients with AKI mimicking RPGN.

  8. Oral hygiene care of patients with oral cancer during postoperative irradiation. An alleviating effect on acute radiation mucositis

    To evaluate the effect of oral hygiene care of patients with oral cancer on alleviating acute radiation mucositis. Eighteen patients receiving postoperative radiotherapy for tongue and oral floor cancer were evaluated. Radiotherapy was given in 2 Gy per fraction, 5 times a week for a total dose of 50 Gy in most patients. Radiation field included the tongue and oral floor. During radiotherapy, 8 patients were treated by dento-maxillofacial radiologists with special concern on oral hygiene (oral hygiene group) and the remaining 10 patients were treated with routine dental care (standard medication group). Mucositis were evaluated using JCOG grade and EORTC/RTOG score by radiotherapists or dento-maxillofacial radiologists at 10 Gy intervals. Oral hygiene plans comprised motivation to maintain oral hygiene and establishing the habits of oral self care 4 times per day. Once a week, oral hygiene and oral cleaning of patients were checked by dento-maxillofacial radiologists. Oral self care included mechanical tooth brushing and a chemical mouthwash. No patients with grade 3 and score 4 mucositis were noted in the oral hygiene group. Severe mucositis occurred less frequently in the oral hygiene group than in the standard medication group. Interruption of radiotherapy due to severe mucositis did not occur in the oral hygiene group. On the other hand, interruption of radiotherapy occurred in four patients in the standard medication group, and in three it was due to severe oral pain. Our results suggested that our method of oral hygiene was more effective for alleviating acute radiation mucositis than other methods so far reported. In addition, our method is considered to be useful in preventing rampant dental caries and severe periodontitis due to the xerostomia induced by radiotherapy. (author)

    Importance Chronic periodontitis, a destructive inflammatory disorder of the supporting structures of the teeth, is prevalent in patients with diabetes. Limited evidence suggests that periodontal therapy may improve glycemic control. Objective To determine if non-surgical periodontal treatment reduces hemoglobin A1c (HbA1c) in persons with type 2 diabetes (DM) and moderate to advanced chronic periodontitis. Design, Setting and Participants The Diabetes and Periodontal Therapy Trial (DPTT) is a 6-month, single-masked, randomized, multi-center clinical trial. Participants had DM, were taking stable doses of medications, had HbA1c ≥7% and <9%, and untreated periodontitis. Five hundred fourteen participants were enrolled between November 2009 and March 2012 from diabetes and dental clinics and communities affiliated with five academic medical centers. Intervention The treatment group (n=257) received scaling and root planing plus chlorhexidine oral rinse at baseline, and supportive periodontal therapy at three and six months. The control group (n=257) received no treatment for six months. Main Outcome Measure Difference in HbA1c change from baseline between groups at six months. Secondary outcomes included changes in probing pocket depths, clinical attachment loss, bleeding on probing, gingival index, fasting glucose, and the Homeostasis Model Assessment (HOMA2). Results Enrollment was stopped early due to futility. At 6 months, the periodontal therapy group increased HbA1c 0.17% (1.0) (mean (SD)) compared to 0.11% (1.0) in the control group, with no significant difference between groups based on a linear regression model adjusting for clinical site (mean difference = -0.05%; 95% Confidence Interval (CI): -0.23%, 0.12%; p=0.55). Probing depth, clinical attachment loss, bleeding on probing and gingival index measures improved in the treatment group compared to the control group at six months with adjusted between-group differences of 0.33mm (95% CI: 0.26, 0.39), 0

    Full Text Available Hayley Uden1, Saravana Kumar21Podiatry Department, University of South Australia, Adelaide, South Australia, Australia; 2Post Doctoral Senior Research Fellow, International Centre for Allied Health Evidence, University of South Australia, Adelaide, South Australia, AustraliaBackground: An intoed gait pattern is one of the most common referrals for children to an orthopedic consultation. Parental concern as to the aesthetics of the child’s gait pattern and/or its symptomatic nature will primarily drive these referrals during a child’s early developmental years. Whilst some of these referrals prove to be the result of a normal growth variant, some children will present with a symptomatic intoed gait pattern. Various treatments, both conservative and surgical, have been proposed including: braces, wedges, stretches and exercises, shoe modifications, and surgical procedures. However, which treatments are effective and justified in the management of this condition is not clear within the literature. The aim of this systematic review was to therefore identify and critique the best available evidence for the non-surgical management of an intoed gait pattern in a pediatric population.Method: A systematic review was conducted of which only experimental studies investigating a management option for an intoeing gait pattern were included. Studies needed to be written in English, pertaining to a human pediatric population, and published within a peer reviewed journal. Electronic databases were searched: Ovid (Medline, EMBASE, AMED, PubMed, SportDiscus, CINAHL, and Cochrane Library. The National Health and Medical Research Council’s designation of levels of hierarchy and the Critical Appraisal Skills Programme cohort studies critical appraisal tool were used.Results: Five level IV studies were found. The studies were of varied quality and with mixed results. Gait plates, physiologic/standardized shoes, and orthotic devices (with gate plate extension

  13. Acute coronary stent thrombosis in cancer patients: a case series report.

    Lee, Joo Myung; Yoon, Chang-Hwan

    2012-07-01

    There have been a growing numbers of patients diagnosed with malignancy and coronary artery disease simultaneously or serially. In the era of percutaneous coronary intervention (PCI), stent thrombosis has been a rare but challenging problem. Recently, we experienced two unique cases of acute stent thrombosis in patients with malignancy. The first case showed acute and subacute stent thrombosis after PCI. The second case revealed simultaneous thromboses in stent and non-treated native coronary artery. We believe that we need rigorous precautions in the treatment of patients with coronary artery disease and malignancy, especially with regards to deciding how and whether to revascularize, as well as which anti-platelet agents to select.

    Abstract: Genomic profiling has transformed our understanding of the genetic basis of acute lymphoblastic leukemia (ALL). Recent years have seen a shift from microarray analysis and candidate gene sequencing to next-generation sequencing. Together, these approaches have shown that many ALL subtypes are characterized by constellations of structural rearrangements, submicroscopic DNA copy number alterations, and sequence mutations, several of which have clear implications for risk stratification and targeted therapeutic intervention.

  15. Primary prevention and treatment of venous thromboembolic events in patients with gastrointestinal cancers - Review.

    Riess, Hanno; Habbel, Piet; Jühling, Anja; Sinn, Marianne; Pelzer, Uwe

    2016-03-15

    Venous thromboembolism event (VTE) is a common and morbid complication in cancer patients. Patients with gastrointestinal cancers often suffer from symptomatic or incidental splanchnic vein thrombosis, impaired liver function and/or thrombocytopenia. These characteristics require a thorough risk/benefit evaluation for individual patients. Considering the risk factors for the development of VTE and bleeding events in addition to recent study results may be helpful for correct initiation of primary pharmacological prevention and treatment of cancer-associated thrombosis (CAT), preferably with low molecular weight heparins (LMWH). Whereas thromboprophylaxis is most often recommended in hospitalized surgical and non-surgical patients with malignancy, there is less agreement as to its duration. With regard to ambulatory cancer patients, the lack of robust data results in low grade recommendations against routine use of anticoagulant drugs. Anticoagulation with LMWH for the first months is the evidence-based treatment for acute CAT, but duration of secondary prevention and the drug of choice are unclear. Based on published guidelines and literature, this review will focus on prevention and treatment strategies of VTE in patients with gastrointestinal cancers. PMID:26989461

The mean size of the GNPs (29 nm, as determined by dynamic light scattering, enlarged to 82 nm after herceptin immobilization. The in vitro cell culture experiment indicated that human skin cells (FB proliferated well in the presence of herceptin-conjugated GNP (GNP–Her, while most of the breast cancer cells (SK-BR3 had died. To elucidate the mechanism of cell death, the interaction of breast cancer cells with GNP–Her was tracked by confocal laser scanning microscopy. Consequently, GNP–Her was found to be bound precisely to the membrane of the breast cancer cell, which became almost saturated after 6 hours incubation. This shows that the progression signal of SK-BR3 cells is retarded completely by the precise binding of antibody to the human epidermal growth factor receptor 2 receptor of the breast cancer cell membrane, causing cell death.Keywords: herceptin, gold nanoparticles, SK-BR3 cells, intracellular uptake

This report discusses the consequences of applying the CC, LOCF and MI for the ITT analysis of published data (analysed using the MM method from the Fracture Reduction Evaluation (FREE trial. Methods The FREE trial was a randomised, non-blinded study comparing balloon kyphoplasty with non-surgical care for the treatment of patients with acute painful vertebral fractures. Patients were randomised to treatment (1:1 ratio, and stratified for gender, fracture aetiology, use of bisphosphonates and use of systemic steroids at the time of enrolment. Six outcome measures - Short-form 36 physical component summary (SF-36 PCS scale, EuroQol 5-Dimension Questionnaire (EQ-5D, Roland-Morris Disability (RMD score, back pain, number of days with restricted activity in last 2 weeks, and number of days in bed in last 2 weeks - were analysed using four methods for dealing with missing data: CC, LOCF, MM and MI analyses. Results There were no missing data in baseline covariates values, and only a few missing baseline values in outcome variables. The overall missing-response level increased during follow-up (1 month: 14.5%; 24 months: 28%, corresponding to a mean of 19% missing data during the entire period. Overall patterns of missing response across time were similar for each treatment group. Almost half of all randomised patients were not available for a CC analysis, a maximum of 4% were not included in the LOCF analysis, and all randomised patients were included in the MM and MI analyses. Improved estimates of treatment effect were observed with LOCF, MM and MI compared with CC; only MM provided improved

    Purpose: Transforming growth factor-beta1 is related to adverse events in radiochemotherapy. We investigated TGFB1 genetic variability in relation to quality of life-impairing acute organ toxicity (QAOT) of neoadjuvant radiochemotherapy under clinical trial conditions. Methods and Materials: Two independent patient cohorts (n = 88 and n = 75) diagnosed with International Union Against Cancer stage II/III rectal cancer received neoadjuvant radiation doses of 50.4 Gy combined with 5-fluorouracil-based chemotherapy. Toxicity was monitored according to Common Terminology Criteria for Adverse Events. QAOT was defined as a CTCAE grade {>=}2 for at least one case of enteritis, proctitis, cystitis, or dermatitis. Nine germline polymorphisms covering the common genetic diversity in the TGFB1 gene were genotyped. Results: In both cohorts, all patients carrying the TGFB1 Pro25 variant experienced QAOT (positive predictive value of 100%, adjusted p = 0.0006). In a multivariate logistic regression model, gender, age, body mass index, type of chemotherapy, or disease state had no significant impact on QAOT. Conclusion: The TGFB1 Pro25 variant could be a relevant marker for individual treatment stratification and carriers may benefit from adaptive clinical care or specific radiation techniques.

  20. Identification of biomarkers for radiation-induced acute intestinal symptoms (RIAISs) in cervical cancer patients by serum protein profiling

    Radiation-induced acute intestinal symptoms (RIAISs) are the most frequent complication of radiotherapy that causes great pain and limits the treatment efficacy. The aim of this study was to identify serum biomarkers of RIAISs in cervical cancer patients by surface-enhanced laser desorption/ionization time-of-flight mass spectrometry (SELDI-TOF MS). Serum samples were collected from 66 cervical cancer patients prior to pelvic radiotherapy. In our study, RIAISs occurred in 11 patients. An additional 11 patients without RIAISs were selected as controls, whose age, stage, histological type and treatment methods were matched to RIAISs patients. The 22 sera were subsequently analyzed by SELDI-TOF MS, and the resulting protein profiles were evaluated to identify biomarkers using appropriate bioinformatics tools. Comparing the protein profiles of serum samples from the RIAIS group and the control group, it was found that 22 protein peaks were significantly different (P < 0.05), and six of these peaks with mass-to-charge (m/z) ratios of 7514.9, 4603.94, 6887.41, 2769.21, 3839.72 and 4215.7 were successfully identified. A decision tree model of biomarkers was constructed based on three biomarkers (m/z 1270.88, 1503.23 and 7514.90), which separated RIAIS-affected patients from the control group with an accuracy of 81%. This study suggests that serum proteomic analysis by SELDI-TOF MS can identify cervical cancer patients that are susceptible to RIAISs prior to pelvic radiotherapy. (author)

  1. Can dosimetric parameters predict acute hematologic toxicity in rectal cancer patients treated with intensity-modulated pelvic radiotherapy?

    To identify dosimetric parameters associated with acute hematologic toxicity (HT) in rectal cancer patients undergoing concurrent chemotherapy and intensity-modulated pelvic radiotherapy. Ninety-three rectal cancer patients receiving concurrent capecitabine and pelvic intensity-modulated radiation therapy (IMRT) were analyzed. Pelvic bone marrow (PBM) was contoured for each patient and divided into three subsites: lumbosacral spine (LSS), ilium, and lower pelvis (LP). The volume of each site receiving 5–40 Gy (V 5, V10, V15, V20, V30, and V40, respectively) as well as patient baseline clinical characteristics was calculated. The endpoint for hematologic toxicity was grade ≥ 2 (HT2+) leukopenia, neutropenia, anemia or thrombocytopenia. Logistic regression was used to analyze correlation between dosimetric parameters and grade ≥ 2 hematologic toxicity. Twenty-four in ninety-three patients experienced grade ≥ 2 hematologic toxicity. Only the dosimetric parameter V40 of lumbosacral spine was correlated with grade ≥ 2 hematologic toxicity. Increased pelvic lumbosacral spine V40 (LSS-V40) was associated with an increased grade ≥ 2 hematologic toxicity (p = 0.041). Patients with LSS-V40 ≥ 60 % had higher rates of grade ≥ 2 hematologic toxicity than did patients with lumbosacral spine V40 < 60 % (38.3 %, 18/47 vs.13 %, 6/46, p =0.005). On univariate and multivariate logistic regression analysis, lumbosacral spine V40 and gender was also the variable associated with grade ≥ 2 hematologic toxicity. Female patients were observed more likely to have grade ≥ 2 hematologic toxicity than male ones (46.9 %, 15/32 vs 14.8 %, 9/61, p =0.001). Lumbosacral spine -V40 was associated with clinically significant grade ≥ 2 hematologic toxicity. Keeping the lumbosacral spine -V40 < 60 % was associated with a 13 % risk of grade ≥ 2 hematologic toxicity in rectal cancer patients undergoing concurrent chemoradiotherapy

  2. Gender affects acute organ toxicity during radiochemotherapy for rectal cancer: Long-term results of the German CAO/ARO/AIO-94 phase III trial

    Introduction: The CAO/ARO/AIO-94 phase-III-trial demonstrated a significant improvement of preoperative chemoradiotherapy (CRT) versus postoperative CRT on local control for UICC stage II/III rectal cancer patients, but no effect on long-term survival. In this add-on evaluation, we investigated the association of gender and age with acute toxicity and outcome. Patients and methods: According to actual treatment analyses, 654 of 799 patients had received pre- (n = 406) or postoperative CRT (n = 248); in 145 patients postoperative CRT was not applied. Gender, age and clinicopathological parameters were correlated with CRT-associated acute toxicity and survival. Results: The 10-year survival was higher in women than in men, with 72.4% versus 65.6% for time to recurrence (p = 0.088) and 62.7% versus 58.4% for overall-survival (OS) (p = 0.066), as expected. For patients receiving CRT, women showed higher hematologic (p < 0.001) and acute organ toxicity (p < 0.001) in the entire cohort as well as in subgroup analyses according to pre- (p = 0.016) and postoperative CRT (p < 0.001). Lowest OS was seen in patients without acute toxicity (p = 0.0271). Multivariate analyses for OS showed that acute organ toxicity (p = 0.034) was beneficial while age (p < 0.001) was associated with worse OS. Discussion: Female gender is significantly associated with CRT-induced acute toxicity in rectal cancer. Acute toxicity during CRT may be associated with improved long-term outcome

    Publication Abstract:  Philadelphia chromosome-like acute lymphoblastic leukemia (Ph-like ALL) is characterized by a gene-expression profile similar to that of BCR-ABL1-positive ALL, alterations of lymphoid transcription factor genes, and a poor outcome. The frequency and spectrum of genetic alterations in Ph-like ALL and its responsiveness to tyrosine kinase inhibition are undefined, especially in adolescents and adults. We performed genomic profiling of 1725 patients with precursor B-cell ALL and detailed genomic analysis of 154 patients with Ph-like ALL.

    The aim of the study was to estimate interfractional deviations in patient and prostate position, the impact of the frequency of online verification on the treatment margins, and to assess acute radiation reactions of high-dose external beam image-guided intensity-modulated radiotherapy (IG-IMRT) of localized prostate cancer. IG-IMRT was performed by daily online verification of implanted fiducial prostate markers using a megavoltage electronic portal imaging device (EPID). A total of 1011 image-guided treatment fractions from 23 consecutive unselected prostate cancer patients were analyzed. The median total dose was 79.2 Gy (range 77.4-81.0 Gy). Acute radiation reactions were assessed weekly during radiotherapy using the Common Terminology Criteria for Adverse Events (CTCAE) v.4.03. A relevant combined patient set-up and prostate motion population random error of 4-5 mm was observed. Compared to daily IGRT, image guidance every other day required an expansion of the CTV-PTV (clinical target volume-planning target volume) margin of 8.1, 6.6, and 4.1 mm in the longitudinal, vertical, and lateral directions, thereby, increasing the PTV by approximately 30-40 %. No grade 3 or 4 acute radiation reactions were observed with daily IG-IMRT. A high dose with surprisingly low acute toxicity can be applied with daily IG-IMRT using implanted fiducial prostate markers. Daily image guidance is clearly superior to image guidance every other fraction concerning adequate target coverage with minimal margins. (orig.)

  5. Primary and secondary prevention of acute complications of radiotherapy of head and neck cancers

    Purpose: the standard treatment of head and neck cancers associates a 70 Gy irradiation and weekly concomitant chemotherapy by 5-fluoro-uracils and cisplatin or targeted therapy by Erbitux. A retrospective study realised at the Francois Baclesse center in 2004-2005 for 84 patients suffering of ear-nose-throat cancers whom treatment was a concomitant chemoradiotherapy, showed the noxious effects of the treatment on the patients nutritional situation: weight loss for 90% of patients; temporary interruption or definitive stop of radiotherapy for 28% of patients. based on this observation, a preventive approach of the nutritional risk was implemented. The objective was to reduce the malnutrition risk linked to radiotherapy associated to chemotherapy or to the targeted therapy. (N.C.)

    There is paucity of data in pediatric Acute Myeloid Leukemia (AML) from developing countries. We analyzed the outcomes of 65 consecutive patients with pediatric AML treated at our centre from January-2008 to May-2013. The median event free survival (EFS) and overall survival (OS) were 12.6 and 14.6 months respectively. Patients with good-risk cytogenetics had a better EFS (p = 0.004) and OS (p = 0.01). Overall, these results are not comparable to that observed in other centres globally and leaves scope for further improvement. This includes implementing allogeneic bone marrow transplantation as a treatment for all children with high-risk AML. PMID:27429516

    Acute myelogenous leukemia (AML) is characterized by uncontrolled proliferation of the cells of myeloid origin. It can present at all ages, but is more common in adults. It is one of the most common leukemias in adults and continues to pose significant challenge in diagnosis and long-term management.AML is a disease at the forefront of genetic and genomic approaches to medicine. It is a disease that has witnessed rapid advances in terms of diagnosis, classification, prognosis and ultimately individualized therapy. Newly diagnosed AML patients are now routinely stratified according to cytogenetics and molecular markers which guides long-term prognosis and treatment. On the other hand, with few exceptions, the initial treatment (also known as induction treatment) of AML has been 'one-size-fits-all'. It remains a great challenge for patients and physicians to consolidate and translate these advances into eventual success in clinic [1, 2]. PMID:23288651

  10. Researchers Identify Genomic Alterations Associated with Drug-Targetable Kinase Activation in Ph-like Acute Lymphoblastic Leukemia | Office of Cancer Genomics

    Acute lymphoblastic leukemia (ALL) is the most prevalent cancer among children and young adults, and standard treatments within this population generally result in favorable outcomes. By contrast, one particular subtype of this disease, Philadelphia chromosome-like ALL (Ph-like ALL), is associated with inferior outcomes. Ph-like ALL exhibits a gene expression profile similar to chromosome 9:22 translocation positive ALL, yet it lacks the characteristic BCR-ABL fusion protein.
