    Conventional neoadjuvant chemoradiotherapy (CRT) is suboptimal for systemic control in locally advanced rectal cancer (LARC). To improve systemic control, we developed an alternative approach in which an intensified oxaliplatin and capecitabine (XELOX) chemotherapy regimen was administered concomitantly with radiation and extended to the resting period (consolidation chemotherapy) for high-risk LARC. The aim of the current study was to evaluate the short-term efficacy and toxicity of this strategy. Patients with high-risk LARC were treated with CRT. Two cycles of XELOX were administered concomitantly with radiation. Thereafter, an additional cycle of the same regimen was administered during the resting period after completion of CRT. Tumor response, toxicities and surgical complications were recorded. This study includes 36 patients treated with the above strategy. All patients completed the planned concurrent CRT. Because of grade 3 toxicities, 2 patients were unable to complete the additional chemotherapy. Grade 3 toxicities were leucopenia (2.8 %), diarrhea (2.8 %) and radiodermatitis (2.8 %). All patients underwent optimal surgery with total mesorectal excision (TME) and a sphincter-saving procedure was performed in 27 patients (75 %). There was no perioperative mortality. Postoperative complications developed in 7 patients (19.4 %). Pathologic complete regression (pCR),''nearly pCR'' (major regression), and moderate or minimal regression were achieved in 13 (36.1 %), 16 (44.4 %), and 7 patients (19.5 %), respectively. The preliminary results suggest that a XELOX regimen initially administered concomitantly with radiotherapy and then extended to the resting period in high-risk LARC patients is well tolerated. The strategy is highly effective in terms of pCR and nearly pCR rates, and thus warrants further investigation. (orig.)

    Background: To review treatment toxicity for patients with pancreatic and ampullary cancer treated with proton therapy at our institution. Material and methods: From March 2009 through April 2012, 22 patients were treated with proton therapy and concomitant capecitabine (1000 mg PO twice daily) for resected (n = 5); marginally resectable (n = 5); and unresectable/inoperable (n = 12) biopsy-proven pancreatic and ampullary adenocarcinoma. Two patients with unresectable disease were excluded from the analysis for reasons unrelated to treatment. Proton doses ranged from 50.40 cobalt gray equivalent (CGE) to 59.40 CGE. Results: Median follow-up for all patients was 11 (range 5-36) months. No patient demonstrated any grade 3 toxicity during treatment or during the follow-up period. Grade 2 gastrointestinal toxicities occurred in three patients, consisting of vomiting (n = 3); and diarrhea (n = 2). Median weight loss during treatment was 1.3 kg (1.75% of body weight). Chemotherapy was well-tolerated with a median 99% of the prescribed doses delivered. Percentage weight loss was reduced (p = 0.0390) and grade 2 gastrointestinal toxicity was eliminated (p = 0.0009) in patients treated with plans that avoided anterior and left lateral fields which were associated with reduced small bowel and gastric exposure. Discussion: Proton therapy may allow for significant sparing of the small bowel and stomach and is associated with a low rate of gastrointestinal toxicity. Although long-term follow-up will be needed to assess efficacy, we believe that the favorable toxicity profile associated with proton therapy may allow for radiotherapy dose escalation, chemotherapy intensification, and possibly increased acceptance of preoperative radiotherapy for patients with resectable or marginally resectable disease.

    Purpose: Newer radiation techniques, and the application of continuous 5-FU exposure during radiation therapy using oral capecitabine may improve the treatment of anal cancer. This phase 1, dose-finding study assessed the feasibility and efficacy of simultaneous integrated boost–intensity modulated radiation therapy (SIB-IMRT) with concomitant capecitabine and mitomycin C in locally advanced anal cancer, including pharmacokinetic and pharmacogenetic analyses. Methods and Materials: Patients with locally advanced anal carcinoma were treated with SIB-IMRT in 33 daily fractions of 1.8 Gy to the primary tumor and macroscopically involved lymph nodes and 33 fractions of 1.5 Gy electively to the bilateral iliac and inguinal lymph node areas. Patients received a sequential radiation boost dose of 3 × 1.8 Gy on macroscopic residual tumor if this was still present in week 5 of treatment. Mitomycin C 10 mg/m{sup 2} (maximum 15 mg) was administered intravenously on day 1, and capecitabine was given orally in a dose-escalated fashion (500-825 mg/m{sup 2} b.i.d.) on irradiation days, until dose-limiting toxicity emerged in ≥2 of maximally 6 patients. An additional 8 patients were treated at the maximum tolerated dose (MTD). Results: A total of 18 patients were included. The MTD of capecitabine was determined to be 825 mg/m{sup 2} b.i.d. The predominant acute grade ≥3 toxicities included radiation dermatitis (50%), fatigue (22%), and pain (6%). Fifteen patients (83% [95%-CI: 66%-101%]) achieved a complete response, and 3 (17%) patients a partial response. With a median follow-up of 28 months, none of the complete responders, and 2 partial responders had relapsed. Conclusions: SIB-IMRT with concomitant single dose mitomycin C and capecitabine 825 mg/m{sup 2} b.i.d. on irradiation days resulted in an acceptable safety profile, and proved to be a tolerable and effective treatment regimen for locally advanced anal cancer.

    Purpose: To determine the maximum tolerated radiation dose (MTD) of an integrated boost to the tumor subvolume infiltrating vessels, delivered simultaneously with radical dose to the whole tumor and concomitant capecitabine in patients with pretreated advanced pancreatic adenocarcinoma. Methods and Materials: Patients with stage III or IV pancreatic adenocarcinoma without progressive disease after induction chemotherapy were eligible. Patients underwent simulated contrast-enhanced four-dimensional computed tomography and fluorodeoxyglucose-labeled positron emission tomography. Gross tumor volume 1 (GTV1), the tumor, and GTV2, the tumor subvolume 1 cm around the infiltrated vessels, were contoured. GTVs were fused to generate Internal Target Volume (ITV)1 and ITV2. Biological tumor volume (BTV) was fused with ITV1 to create the BTV+Internal Target Volume (ITV) 1. A margin of 5/5/7 mm (7 mm in cranium-caudal) was added to BTV+ITV1 and to ITV2 to create Planning Target Volume (PTV) 1 and PTV2, respectively. Radiation therapy was delivered with tomotherapy. PTV1 received a fixed dose of 44.25 Gy in 15 fractions, and PTV2 received a dose escalation from 48 to 58 Gy as simultaneous integrated boost (SIB) in consecutive groups of at least 3 patients. Concomitant chemotherapy was capecitabine, 1250 mg/m{sup 2} daily. Dose-limiting toxicity (DLT) was defined as any treatment-related G3 nonhematological or G4 hematological toxicity occurring during the treatment or within 90 days from its completion. Results: From June 2005 to February 2010, 25 patients were enrolled. The dose escalation on the SIB was stopped at 58 Gy without reaching the MTD. One patient in the 2{sup nd} dose level (50 Gy) had a DLT: G3 acute gastric ulcer. Three patients had G3 late adverse effects associated with gastric and/or duodenal mucosal damage. All patients received the planned dose of radiation. Conclusions: A dose of 44.25 Gy in 15 fractions to the whole tumor with an SIB of 58 Gy to small

  8. Comparison of two preoperative chemoradiotherapy regimens for locally advanced rectal cancer: capecitabine alone versus capecitabine plus irinotecan

    International Nuclear Information System (INIS)

    To compare the short-term tumor response and long-term clinical outcome of two preoperative chemoradiotherapy (CRT) regimens for locally advanced rectal cancer. This study included 231 patients scheduled for preoperative CRT using two chemotherapeutic protocols from April 2003–August 2006. Pelvic radiotherapy (50.4 Gy) was delivered concurrently with capecitabine (n = 148) or capecitabine/irinotecan (n = 83). Surgery was performed 4–8 weeks after CRT completion. Tumor responses to CRT were assessed using both radiologic and pathologic measurements. Radiologic responses were evaluated by magnetic resonance volumetry, which was performed at the initial work-up and after completion of preoperative CRT just before surgery. Pathologic responses were assessed with downstaging (ypStage 0-1) and grading tumor regression. Clinical outcomes were evaluated in terms of local control, relapse-free survival, and overall survival rates. Radiologic examination demonstrated that tumor volume decreased by 65.6% in the capecitabine group and 66.8% capecitabine/irinotecan group (p = 0.731). Postoperative pathologic stage determination showed that tumor downstaging occurred in 44.1% of the capecitabine group and 48.6% of the capecitabine/irinotecan group (p = 0.538). The sum of tumor regression grade 3 (near complete response) and 4 (complete response) after CRT were 28.6% in the capecitabine group and 37.5% in the capecitabine/irinotecan group (p = 0.247). There were no significant differences between the two groups in 5-year local control (91.7% vs. 92.5%; p = 0.875), relapse-free survival (80.8% vs. 77.2%; p = 0.685), and overall survival (88.4% vs. 90.4%; p = 0.723). This study revealed no differences in the short-term tumor response and long-term clinical outcome between preoperative capecitabine and capecitabine/irinotecan CRT regimens for locally advanced rectal cancer

    Full Text Available Abstract. Background. Facial expressions of emotions represent classic stimuli for the study of social cognition. Developing virtual dynamic facial expressions of emotions, however, would open-up possibilities, both for fundamental and clinical research. For instance, virtual faces allow real-time Human-Computer retroactions between physiological measures and the virtual agent. Objectives. The goal of this study was to initially assess concomitant and construct validity of a newly developed set of virtual faces expressing 6 fundamental emotions (happiness, surprise, anger, sadness, fear, or disgust. Recognition rates, facial electromyography (zygomatic major and corrugator supercilii muscles, and regional gaze fixation latencies (eyes and mouth regions were compared in 41 adult volunteers (20 ♂, 21 ♀ during the presentation of video clips depicting real vs. virtual adults expressing emotions. Results. Emotions expressed by each sets of stimuli were similarly recognized, both by men and women. Accordingly, both sets of stimuli elicited similar activation of facial muscles and similar ocular fixation times in eye regions from man and woman participants. Conclusion. Further validation studies can be performed with these virtual faces among clinical populations known to present social cognition difficulties. Brain-Computer Interface studies with feedback-feed forward interactions based on facial emotion expressions can also be conducted with these stimuli.

    Full Text Available Capecitabine, an oral prodrug of 5-fluorouracil (5-FU, is approved for early-stage and advanced colorectal cancer and metastatic breast cancer. Cardiotoxicity of 5-FU is well described in the literature. However, cardiac adverse effects of capecitabine are poorly described. We report a case of coronary vasospasm induced by capecitabine. A 41-year-old female with metastatic breast cancer presented with chest pain 3 days after starting capecitabine. The chest pain was relieved by rest and exacerbated by exertion. Her physical examination was unremarkable except for a rapid heart rate of 100 bpm. Electrocardiogram test showed no acute ischemic changes. Troponin tests were negative. CT angiography of the chest was negative for acute pulmonary embolism. An echocardiogram showed a left ventricular ejection fraction of 60% without any wall motion abnormalities. The chest pain resolved with aspirin and analgesic use. She was discharged following an inconclusive cardiac workup. Further use of capecitabine was discontinued.

    Full Text Available Abstract Introduction Celiac disease and cystic fibrosis have many common manifestations, such as malabsorption, steatorrhea and growth failure, and were for many years recognized as one clinical entity. Since their recognition as two separate diseases, their co-existence in a patient has been described sporadically; around 20 cases have been described in the literature. Taking into consideration the incidences of the two diseases, the chance of them occurring together is one in 2,000,000 in the general population. Case presentation We describe the case of a five-year-old boy of Turkish ethnicity with both celiac disease and cystic fibrosis, who presented initially with a skin hemorrhage. The diagnosis of celiac disease was made with a positive serum anti-tissue transglutaminase antibody test and the presence of HLA-DQ2 heterodimer, and confirmed on histology with small intestinal villous atrophy. A positive sweat test confirmed the diagnosis of associated cystic fibrosis. To the best of our knowledge there has been no previous report of this rare presentation of associated celiac disease and cystic fibrosis. Conclusion The clinical significance of this case is the consideration of malabsorption with both celiac disease and cystic fibrosis in patients who present with unexplained coagulopathy.

    Purpose: Radiosensitizing chemotherapy improves the outcomes in comparison with radiation alone for gastrointestinal cancers. The delivery of radiation therapy with yttrium90 ({sup 90}Y) radioembolization, in combination with the radiosensitizing chemotherapeutic agent capecitabine, provides the opportunity to enhance the effects of radiation on hepatic malignancies. This phase 1 study sought to determine the maximum tolerated dose (MTD) of {sup 90}Y plus capecitabine in patients with cholangiocarcinoma or liver metastases confined to the liver. Methods and Materials: Patients were given initial treatment at full-dose capecitabine during days 1 to 14 of a 21-day cycle. At days 1 to 7 of the second cycle, whole-liver {sup 90}Y was given at the test dose, after which time capecitabine was continued. Dose-limiting toxicity (DLT) was determined 6 weeks after {sup 90}Y infusion. If a DLT was not observed, the {sup 90}Y dose was escalated. The planned dose cohorts were 110, 130, 150, and 170 Gy. The primary endpoint was to determine the MTD of {sup 90}Y with full-dose capecitabine. Results: Sixteen patients were treated according to the study protocol. Two patients experienced DLTs. Nine patients required capecitabine dose reduction as a result of toxicities attributable to capecitabine alone. The criteria for establishing {sup 90}Y MTD were not met, indicating an MTD of >170 Gy. Conclusion: The MTD of {sup 90}Y delivered in conjunction with capecitabine in the setting of intrahepatic cholangiocarcinoma or metastatic disease confined to the liver exceeds 170 Gy. This is the highest {sup 90}Y dose reported to date and has important implications on combined therapy with the radiosensitizing oral chemotherapeutic capecitabine. Further studies are under way.

  18. Preoperative chemoradiation using oral capecitabine in locally advanced rectal cancer

    International Nuclear Information System (INIS)

    Purpose: Capecitabine (Xeloda) is a new orally administered fluoropyrimidine carbamate that was rationally designed to exert its effect by tumor-selective activation. We attempted to evaluate the efficacy and toxicity of preoperative chemoradiation using capecitabine in locally advanced rectal cancer. Methods and Materials: Between July 1999 and March 2001, 45 patients with locally advanced rectal cancer (cT3/T4 or N+) were treated with preoperative chemoradiation. Radiation of 45 Gy/25 fractions was delivered to the pelvis, followed by a 5.4 Gy/3 fractions boost to the primary tumor. Chemotherapy was administered concurrent with radiotherapy and consisted of 2 cycles of 14-day oral capecitabine (1650 mg/m2/day) and leucovorin (20 mg/m2/day), each of which was followed by a 7-day rest period. Surgery was performed 6 weeks after the completion of chemoradiation. Results: Thirty-eight patients received definitive surgery. Primary tumor and node downstaging occurred in 63% and 90% of patients, respectively. The overall downstaging rate, including both primary tumor and nodes, was 84%. A pathologic complete response was achieved in 31% of patients. Twenty-one patients had tumors located initially 5 cm or less from the anal verge; among the 18 treated with surgery, 72% received sphincter-preserving surgery. No Grade 3 or 4 hematologic toxicities developed. Other Grade 3 toxicities were as follows: hand-foot syndrome (7%), fatigue (4%), diarrhea (4%), and radiation dermatitis (2%). Conclusion: These preliminary results suggest that preoperative chemoradiation with capecitabine is a safe, well-tolerated, and effective neoadjuvant treatment modality for locally advanced rectal cancer. In addition, this preoperative treatment has a considerable downstaging effect on the tumor and can increase the possibility of sphincter preservation in distal rectal cancer

  20. Capecitabine maintenance therapy in patients with recurrent or metastatic breast cancer

    International Nuclear Information System (INIS)

    Our objective was to investigate the efficacy and safety of capecitabine maintenance therapy (CMT) after capecitabine-based combination chemotherapy in patients with metastatic breast cancer. The clinical data of 139 metastatic breast cancer patients treated from March 2008 to May 2012 with capecitabine-based combination chemotherapy were retrospectively analyzed. When initial disease control was achieved by the combination chemotherapy, we used CMT for 50 patients, while 37 patients were treated with a different (non-CMT) maintenance therapy. We compared time to progression (TTP), objective response rate, disease control rate, clinical benefit rate, and safety of the two groups, and a sub-group analysis was performed according to pathological characteristics. Sixty-four percent of the patients received a median of six cycles of a docetaxel+capecitabine combination chemotherapy regimen (range 1-45); the median TTP (MTTP) for the complete treatment was 9.43 months (95%CI=8.38-10.48 months) for the CMT group and 4.5 months (95%CI=4.22-4.78 months; P=0.004) for the non-CMT group. The MTTPs for the maintenance therapies administered after the initial capecitabine combined chemotherapy were 4.11 months (95%CI=3.34-4.87 months) for the CMT group and 2.0 months (95%CI=1.63-2.38 months) for the non-CMT group. Gastrointestinal side effects, decreased white blood cells and palmar-plantar erythrodysesthesia were the main adverse reactions experienced with the combination chemotherapies, CMT and non-CMT treatments.

    Our objective was to investigate the efficacy and safety of capecitabine maintenance therapy (CMT) after capecitabine-based combination chemotherapy in patients with metastatic breast cancer. The clinical data of 139 metastatic breast cancer patients treated from March 2008 to May 2012 with capecitabine-based combination chemotherapy were retrospectively analyzed. When initial disease control was achieved by the combination chemotherapy, we used CMT for 50 patients, while 37 patients were treated with a different (non-CMT) maintenance therapy. We compared time to progression (TTP), objective response rate, disease control rate, clinical benefit rate, and safety of the two groups, and a sub-group analysis was performed according to pathological characteristics. Sixty-four percent of the patients received a median of six cycles of a docetaxel+capecitabine combination chemotherapy regimen (range 1-45); the median TTP (MTTP) for the complete treatment was 9.43 months (95%CI=8.38-10.48 months) for the CMT group and 4.5 months (95%CI=4.22-4.78 months; P=0.004) for the non-CMT group.

    Full Text Available Capecitabine is an orally active prodrug of fluorouracil and is extensively used as an antineoplastic agent. It is converted to 5-Fluorouracil in the liver and tumor tissues. Warfarin is an anticoagulant agent for preventing and treating venous and arterial thrombosis and embolism and is metabolized by cytochrome P450 isoenzymes in the liver. Preclinical in vitro studies using human liver microsomes report no inhibitory effects between capecitabine and substrates of cytochrome P. However, the concomitant administration of capecitabine and warfarin resulted in INR elevation in the cases previously reported in the literature. The exact mechanism of this interaction is unknown but may be related to downregulation of cytochrome P450 2C9 by capecitabine or its metabolites. We report on the possible adverse interaction between capecitabine and warfarin in a patient with metastatic breast cancer and critically review the existing literature on this topic. Physicians should be aware of adverse reactions arising from the combined use of capecitabine and warfarin. In the light of the current data, INR levels should be closely monitored in patients using these drugs together.

    Full Text Available Bradford R Hirsch, S Yousuf ZafarDivision of Medical Oncology, Duke University Medical Center, Durham, NC, USAAbstract: 5-Fluorouracil has been a mainstay in the treatment of colorectal cancer for nearly five decades; however, the use of oral formulations of the medication has been gaining increasing traction since capecitabine was approved for use in adjuvant settings by the US Food and Drug Administration in 2005. The use of capecitabine has since spread to a number of off-label indications, including the treatment of advanced or metastatic colorectal cancer and the neoadjuvant treatment of rectal cancer. In light of increasing utilization, it is critical that clinicians have a firm understanding of the literature supporting capecitabine across various settings as well as the attributes of the drug, such as its dosing recommendations, side-effect profile, and use in the elderly. The purpose of this review is to synthesize the literature in a fashion that can be used to help guide decisions. In a setting of increasing focus on cost, the pharmacoeconomic literature is also briefly reviewed.Keywords: colon cancer, colorectal cancer, rectal cancer, capecitabine, Xeloda

    Capecitabine (Xeloda), Roche Laboratories Inc., Nutley, NJ) is an orally administered fluoropyrimidine carbamate that serves as a prodrug of 5-fluorouracil (5-FU), an integral component of chemotherapy (CT) regimens for metastatic colorectal cancer (mCRC). As the drug is orally administered, capecitabine permits greater convenience and flexibility in dosing by eliminating the need for continuous infusion and its potential complications. In phase 3 trials, capecitabine has been used as an alternative to 5-FU, both as a monotherapy and in combination with agents such as oxaliplatin (as XELOX), with good efficacy and tolerability. Combination therapy with capecitabine and irinotecan (XELIRI), however, has produced more variable results, with some dose combinations and schedules resulting in excessive and/or unexplained treatment-related toxicity. Recent initiatives using lower doses of capecitabine and irinotecan, as well as alternative dosing schedules, have resulted in more favorable outcomes (efficacy and tolerability), even in combination with targeted-agents such as bevacizumab. Dose reduction in elderly populations and in those with moderate renal impairment also appears to be important for minimizing toxicity with XELIRI regimens. Although additional phase 3 studies are needed, XELIRI may be an effective base CT regimen, allowing a greater number of treatment options for tumor control in patients with mCRC.

    2016-01-01

    Background There are no randomized phase III trials comparing 5-fluorouracil/mitomycin (FM) versus capecitabine/mitomycin (CM) in combination with radiotherapy (RT) for locally advanced anal cancer. We aim to evaluate the outcomes of patients treated with FM and CM at our institution. Methods Patients with stage I–III anal cancer who initiated curative-intent RT (50–54 Gy) with either CM or FM between 1998 and 2013 at the BC Cancer Agency were reviewed. Cox proportional models were used to analyze the impact of regimen on disease-free survival (DFS) and anal cancer-specific survival (ACSS). Results A total of 300 patients were included. Baseline characteristics were well-distributed between the groups. A total of 194 patients (64.6%) received FM and 106 (35.3%) CM. The 2-year DFS was 79.7% for CM [95% confidence intervals (95% CI), 71.1–88.3%] and 78.8% for FM (95% CI, 73–84.6%); 2-year ACSS was 88.7% for CM (95% CI, 81.8–95.5%) and 87.5% for FM (95% CI, 82.8–92.2%). On multivariate analysis, only HIV status, clinical T size (≤5 vs. >5 cm), and N status (negative vs. positive) remained as significant prognostic factors for both DFS and ACSS. Chemotherapy regimen (CM vs. FM) had no impact on either DFS [P=0.995; hazard ratios (HR) =0.99; 95% CI, 0.57–1.74] or ACSS (P=0.847; HR =0.93; 95% CI, 0.46–1.86). Conclusions In our population-based study, CM and FM concomitant with RT achieved similar DFS and ACSS. Substitution of capecitabine for infusional 5-FU may therefore be a reasonable option for patients and physicians who prefer to avoid the inconvenience and potential complications of a central infusional device.

    Background: Potentiation of anticancer activity of capecitabine is required to improve its therapeutic index. In colorectal cancer (CRC) cells, we evaluated whether the histone deacetylase-inhibitor vorinostat may induce synergistic antitumour effects in combination with capecitabine by modulating the expression of thymidine phosphorylase (TP), a key enzyme in the conversion of capecitabine to 5-florouracil (5-FU), and thymidylate synthase (TS), the target of 5-FU. Methods: Expression of TP and TS was measured by real-time PCR, western blotting and immunohistochemistry. Knockdown of TP was performed by specific small interfering RNA. Antitumour activity of vorinostat was assessed in vitro in combination with the capecitabine active metabolite deoxy-5-fluorouridine (5′-DFUR) according to the Chou and Talay method and by evaluating apoptosis as well as in xenografts-bearing nude mice in combination with capecitabine. Results: Vorinostat induced both in vitro and in vivo upregulation of TP as well as downregulation of TS in cancer cells, but not in ex vivo treated peripheral blood lymphocytes. Combined treatment with vorinostat and 5′-DFUR resulted in a synergistic antiproliferative effect and increased apoptotic cell death in vitro. This latter effect was impaired in cells where TP was knocked. In vivo, vorinostat plus capecitabine potently inhibited tumour growth, increased apoptosis and prolonged survival compared with control or single-agent treatments. Conclusions: Overall, this study suggests that the combination of vorinostat and capecitabine is an innovative antitumour strategy and warrants further clinical evaluation for the treatment of CRC.

    At present there is no established standard of care for metastatic breast cancer and prognosis remains poor, although the use of newer chemotherapeutic regimens has led to modest improvements in survival. Capecitabine, an oral prodrug of 5-fluorouracil, is a promising addition to these approaches, having already shown single-agent activity against metastatic breast cancer. Following a pivotal trial demonstrating that capecitabine confers increased survival when used in combination with docetaxel, it is being investigated intensively in combined regimens using other standard chemotherapeutic agents, as well as with novel molecularly targeted therapies. Among the novel agents, the most intensively studied in combination with capecitabine is trastuzumab. Despite preclinical data suggesting that these two agents might not show additive effects, clinical trials have been very encouraging for both heavily pretreated patients and for patients receiving first-line therapy in the metastatic setting. This work is being further extended in an ongoing trial in the neoadjuvant setting. An initial trial in combination with bevacizumab, enrolling heavily pretreated patients, was less successful, but following the example of the E2100 trial, this combination is being re-examined in less heavily treated patients. In addition, this review discusses ongoing trials with an array of newer molecularly targeted agents. Significant improvement in time to progression has already been demonstrated in the combination of lapatinib and capecitabine compared with capecitabine monotherapy; for the most part, however, these trials are still in early stages.

On the basis of the X-ACT trial, capecitabine was approved by the United States Food and Drug Administration, the National Institute for Clinical Excellence, and the Scottish Medicines Consortium as monotherapy for the adjuvant treatment of stage III colon cancer. The next step was to incorporate capecitabine into combination therapy. The XELOXA trial studied the combination of capecitabine and oxaliplatin (XELOX vs 5-FU/LV and demonstrated 5-year disease-free survival of 66% for XELOX, compared with 60% for 5-FU/LV. The toxicity profile was also quite comparable in the two arms. So both the single agent use of capecitabine as well as in combination with oxaliplatin can be considered as part of the standard of care in management of early colon cancer in appropriately selected patient groups.Keywords: 5-fluorouracil, 5-FU, leucovorin, folinic acid, LV, XELOX, oxaliplatin, FOLFOX

    Full Text Available Muhammad Wasif SaifYale Cancer Center, Yale University School of Medicine, New Haven, CT, USAAbstract: Capecitabine is currently the only novel, orally home-administered fluorouracil prodrug. It offers patients more freedom from hospital visits and less inconvenience and complications associated with infusion devices. The drug has been extensively studied in large clinical trials in many solid tumors, including breast cancer, colorectal cancer, gastric cancer, and many others. Furthermore, the drug compares favorably with fluorouracil in patients with such cancers, with a safe toxicity profile, consisting mainly of gastrointestinal and dermatologic adverse effects. Whereas gastrointestinal events and hand-foot syndrome occur often with capecitabine, the tolerability profile is comparatively favorable. Prompt recognition of severe adverse effects is the key to successful management of capecitabine. Ongoing and future clinical trials will continue to examine, and likely expand, the role of capecitabine as a single agent and/or in combination with other anticancer agents for the treatment of gastrointestinal as well as other solid tumors, both in the advanced palliative and adjuvant settings. The author summarizes the current data on the role of capecitabine in the management of gastrointestinal cancers.

    2010-07-01

    Full Text Available Abstract Introduction There are no known case reports of hepatic steatosis caused by oral fluoropyrimidines such as capecitabine. With increasing use of capecitabine since its approval for the treatment of metastatic colon cancer in 2001, and more recently for adjuvant treatment of colon cancer and treatment of metastatic breast cancer, we can anticipate increased recognition of potential toxicities associated with this 5-fluorouracil derivative. Case presentation We report the case of a 74-year-old Armenian woman who received capecitabine as adjuvant treatment for colon cancer and subsequently developed abnormal liver biochemical tests and radiographic findings in keeping with hepatic steatosis. There was complete reversal of liver enzyme abnormalities with discontinuation of the drug and this patient represents a case of reversible liver injury due to capecitabine. Conclusion In this original case report, capecitabine use was associated with hepatic steatosis. It is important for clinicians to recognize and monitor for this potential toxicity, which may be a cause of abnormal liver enzymes in this patient population.

    A 69-year-old woman was diagnosed with descending colon cancer with multiple liver metastases, and a left hemicolectomy was performed. The patient was treated with capecitabine/oxaliplatin (CapeOX) plus bevacizumab (Bmab). After 5 courses of chemotherapy, the number and size of liver metastases remarkably reduced, and after the 12th course, because of peripheral neuropathy, a "stop-and-go"fashion of administering oxaliplatin (L-OHP) was initiated. After 14 courses, the liver metastases had disappeared. After the 33rd course of L-OHP treatment, the patient started receiving capecitabine therapy. The patient is recurrence-free 3 years after surgery, 14 months after achieving a complete response (CR). We report a case of long-term CR after surgery for descending colon cancer with multiple liver metastases, followed by a "stop-and-go" method of administering L-OHP or CapeOX plus Bmab therapy.

    2008-01-01

    Full Text Available Combinations of capecitabine and a taxane are highly active in metastatic breast cancer, and synergy between capecitabine and docetaxel has also been demonstrated. Such combinations potentially would provide a promising non–anthracycline-based alternative for patients with early breast cancer. Non-anthracycline preoperative regimens are a particularly interesting proposition in human epidermal growth factor receptor 2 (HER2-positive breast cancer, as they offer less cardiotoxicity and thus can be used concomitantly with preoperative trastuzumab therapy. Capecitabine plus docetaxel (XT and trastuzumab with XT (HXT are promising non-anthracycline regimens for the preoperative treatment of women with HER2-negative and HER2-positive breast cancer, respectively. The Xeloda in Neoadjuvant (XeNA trial, an open-label, multicenter, phase II study, independently assesses the efficacy of preoperative XT in HER2-negative and HXT in HER2-positive breast cancer. A particularly important feature of the XeNA study is the use of pathologic complete response (pCR plus near pCR (npCR as the primary endpoint. pCR is associated with long-term survival, and although it is valuable as a surrogate marker, pCR has some limitations. Measurement of residual breast cancer burden (RCB has been proposed as a more practical alternative to predict survival after preoperative chemotherapy. The combination of RCB-0 and RCB-I (npCR expands the subset of patients shown to benefit from preoperative chemotherapy, and achievement of pCR or npCR is associated with long disease-free survival. In XeNA, the sum of pCR and npCR will facilitate correlative studies designed to identify patients most likely to benefit from XT and HXT and may expedite the clinical evaluation of these novel preoperative regimens.

    Full Text Available Gemcitabine is the only chemotherapeutic agent approved by the U.S. Food and Drug Administration (FDA for the treatment of patients with pancreatic cancer [1]. It is also indicated for use in non-small-cell lung cancer, bladder cancer, and is commonly used in other gastrointestinal malignancies. Patients with cancer, specifically pancreatic carcinoma, are at increased risk for thrombosis requiring anticoagulation. In addition, due to aging and common risk factors, cardiac ailments such as atrial fibrillation are also common in this group. In such cases, warfarin is generally the agent of choice In 1999, a potential interaction between gemcitabine and warfarin was reported [2]. In 2002, the manufacturer of gemcitabine, Eli Lilly, reported four similar cases, indicating an incidence of 0.04% suspected drug interaction between gemcitabine and an anticoagulant [3]. They also reported that overall 5.4% of patients undergoing gemcitabine therapy received concomitant anticoagulants [3] Moreover, the U.S. Food and Drug Administration and Roche have added a "Black Box" warning and strengthened the "Precautions" section on the label of capecitabine, which is indicated for the treatment of colorectal and breast cancer [4, 5]. We present the seventh case of a patient with pancreatic cancer complicated by an elevated INR following treatment with concomitant gemcitabine-capecitabinewarfarin first and then gemcitabine-warfarin later.

    5-Fluorouracil (5-FU) and its oral pro-drug capecitabine are widely used in oncology for the treatment of various solid tumours, including colorectal cancers. Cardiotoxicity to these drugs is not an uncommon adverse effect and has been reported in 1%–18% of patients. Capecitabine has been reported to trigger mid-apical Takotsubo syndrome (TS). We describe here the case of a 55-year-old man who presented with cardiogenic shock and ECG signs of ST-elevation myocardial infarction. The symptoms began 28 h after the commencement of capecitabine adjuvant therapy, following a radical right-sided hemicolectomy for low-differentiated adenocarcinoma of the caecum. Echocardiography showed severe global left ventricular dysfunction. Cardiac magnetic resonance imaging showed no signs of late gadolinium enhancement. These clinical, cardiac image study findings and the course of the disease with full recovery within one week were consistent with global TS triggered by the adjuvant therapy capecitabine and presenting with a life-threatening cardiogenic shock. Moreover, we have demonstrated the speedy dynamic of the left ventricular wall motion abnormality with global TS at presentation and basal (inverted) TS findings 4 days later on.

    Full Text Available Gastrointestinal disturbances, such as nausea and vomiting, are considered amongst the main adverse effects associated with oral anticancer drugs due to their fast release in the gastrointestinal tract (GIT. Sustained release formulations with proper release profiles can overcome some side effects of conventional formulations. The current study was designed to prepare sustained release tablets of Capecitabine, which is approved by the Food and Drug Administration (FDA for the treatment of advanced breast cancer, using hydroxypropyl methylcellulose (HPMC, carbomer934P, sodium alginate, and sodium bicarbonate. Tablets were prepared using the wet granulation method and characterized such that floating lag time, total floating time, hardness, friability, drug content, weight uniformity, and in vitro drug release were investigated. The sustained release tablets showed good hardness and passed the friability test. The tablets’ floating lag time was determined to be 30–200 seconds, and it floated more than 24 hours and released the drug for 24 hours. Then, the stability test was done and compared with the initial samples. In conclusion, by adjusting the right ratios of the excipients including release-retarding gel-forming polymers like HPMC K4M, Na alginate, carbomer934P, and sodium bicarbonate, sustained release Capecitabine floating tablet was formulated.

    Drug-induced scleroderma is a rare adverse effect of some chemotherapeutic drugs, such as taxanes and bleomycin. Capecitabine, an oral fluoropyrimidine approved for the treatment of metastatic breast and colon cancer, commonly causes cutaneous side effects including the hand-and-foot syndrome (HFS). Scleroderma-like skin changes associated with HFS associated with capecitabine is rare. However, diffuse scleroderma has never before been reported. We report a case of capecitabine-induced diffuse/systemic scleroderma in an 86-year-old female treated with capecitabine for metastatic colorectal cancer. She developed progressive skin and visceral sclerosis involving the lungs. We discuss the association between chemotherapy and scleroderma. We believe this is the first case of diffuse/systemic capecitabine-induced scleroderma without the presence of HFS. Early diagnosis is essential as fibrosis might be prevented in early stages. The capecitabine should be discontinued as early as possible. PMID:27493845

    A 61-year-old male with a history of metastatic colorectal cancer was referred to our hospital for primary coronary intervention because of acute ST-elevation myocardial infarction. Coronary angiography, however, revealed no significant stenoses. When asked, the patient revealed that capecitabine (Xeloda(R)) was started by his oncologist one day before admission. It is known that this oral 5-FU analogue drug, used in metastatic colorectal cancer, can cause coronary artery spasms. The main treatment of capecitabine-induced vasospasm is discontinuation of the drug. Indeed, after cessation of the drug the patient remained free of symptoms and the ECG abnormalities normalised.

    Palmoplantar erythrodysesthesia (PPE), or hand-foot syndrome, is a cutaneous toxicity under various chemotherapeutics contributing to the most frequent side effects in patients treated with capecitabine (Xeloda®). The pathomechanism of PPE has been unclear. Here, the topical detection of capecitabine in the skin after oral application was shown in 10 patients receiving 2500 mg/m2/day capecitabine. Sweat samples were taken prior to and one week after oral administration of capecitabine. Using high-resolution continuum source absorption spectrometry, the changes in concentrations of fluorine, which is an ingredient of capecitabine, were quantified and statistically analyzed. Here, we show an increase in fluorine concentrations from 40±10 ppb (2±0.5 pM) before capecitabine administration to 27.7±11.8 ppm (14.6±6.5 nM) after application, p<0.001. The results show the secretion of capecitabine on the skin surface after oral administration, indicating a local toxic effect as a possible pathomechanism of PPE.

    Full Text Available Abstract Background Pancreatic cancer is the fourth most common cause of cancer related death in Western countries. Advantages in surgical techniques, radiation and chemotherapy had almost no impact on the long term survival of affected patients. Therefore, the need for better treatment strategies is urgent. HER2, a receptor tyrosine kinase of the EGFR family, involved in signal transduction pathways leading to cell growth and differentiation is overexpressed in a number of cancers, including breast and pancreatic cancer. While in breast cancer HER2 has already been successfully used as a treatment target, there are only limited data evaluating the effects of inhibiting HER2 tyrosine kinases in patients with pancreatic cancer. Methods Here we report the design of a prospective, non-randomized multi-centered Phase II clinical study evaluating the effects of the Fluoropyrimidine-carbamate Capecitabine (Xeloda ® and the monoclonal anti-HER2 antibody Trastuzumab (Herceptin® in patients with non-resectable, HER2 overexpressing pancreatic cancer. Patients eligible for the study will receive Trastuzumab infusions on day 1, 8 and 15 concomitant to the oral intake of Capecitabine from day 1 to day 14 of each three week cylce. Cycles will be repeated until tumor progression. A total of 37 patients will be enrolled with an interim analysis after 23 patients. Discussion Primary end point of the study is to determine the progression free survival after 12 weeks of bimodal treatment with the chemotherapeutic agent Capecitabine and the anti-HER2 antibody Trastuzumab. Secondary end points include patient's survival, toxicity analysis, quality of life, the correlation of HER2 overexpression and clinical response to Trastuzumab treatment and, finally, the correlation of CA19-9 plasma levels and progression free intervals.

  10. Predictive Factors of Lapatinib and Capecitabine Activity in Patients with HER2-Positive, Trastuzumab-Resistant Metastatic Breast Cancer: Results from the Italian Retrospective Multicenter HERLAPAC Study.

    Full Text Available There are no validated predictive markers for lapatinib and capecitabine in patients with trastuzumab-resistant HER2 positive metastatic breast cancer.Data of 148 consecutive patients treated with lapatinib and capecitabine from March 2007 to December 2013 were collected from 13 Italian institutions. Estimates of progression-free survival (PFS and overall survival (OS were obtained with the Kaplan-Meier method and compared with logrank test. The association of clinicopathological variables and the outcome was studied by binary logistic regression analysis and Cox proportional hazard analysis.At a median follow-up of 41 months, median PFS and OS were 7 and 21 months, respectively. Patents with a PFS longer than 7 months had a significantly longer OS, compared with patients with a PFS equal to or shorter than 7 months (36 vs 15 months; p<0.001. Multivariate analysis revealed the benefit of lapatinib-based therapy in terms of PFS and OS was significantly associated with time-to-progression (TTP on prior first-line trastuzumab-based therapy. In particular, each additional month on first-line trastuzumab based therapy was associated with a reduction in hazard of progression and death after the initiation of lapatinib-based therapy of 2% and 4%, respectively.A longer TTP to first line trastuzumab seems to predict a prolonged PFS and OS with subsequent lapatinib and capecitabine.

  11. Phase I Trial of Preoperative Hypofractionated Intensity-Modulated Radiotherapy with Incorporated Boost and Oral Capecitabine in Locally Advanced Rectal Cancer

    International Nuclear Information System (INIS)

    Purpose: To determine the safety and efficacy of preoperative hypofractionated radiotherapy using intensity-modulated radiotherapy (IMRT) and an incorporated boost with concurrent capecitabine in patients with locally advanced rectal cancer. Methods and Materials: The eligibility criteria included adenocarcinoma of the rectum, T3-T4 and/or N1-N2 disease, performance status 0 or 1, and age ≥18 years. Photon IMRT and an incorporated boost were used to treat the whole pelvis to 45 Gy and the gross tumor volume plus 2 cm to 55 Gy in 25 treatments within 5 weeks. The study was designed to escalate the dose to the gross tumor volume in 5-Gy increments in 3-patient cohorts. Capecitabine was given orally 825 mg/m2 twice daily for 7 days each week during RT. The primary endpoint was the maximal tolerated radiation dose, and the secondary endpoints were the pathologic response and quality of life. Results: Eight patients completed RT at the initial dose level of 55 Gy. The study was discontinued because of toxicity-six Grade 3 toxicities occurred in 3 (38%) of 8 patients. All patients went on to definitive surgical resection, and no patient had a pathologically complete response. Conclusion: This regimen, using hypofractionated RT with an incorporated boost, had unacceptable toxicity despite using standard doses of capecitabine and IMRT. Additional research is needed to determine whether IMRT is able to reduce the side effects during and after pelvic RT with conventional dose fractionation

    Purpose We sought to determine whether the combination of ixabepilone plus capecitabine improved overall survival (OS) compared with capecitabine alone in patients with metastatic breast cancer (MBC) previously treated with anthracyclines and taxanes. Patients and Methods A total of 1,221 patients with MBC previously treated with anthracycline and taxanes were randomly assigned to ixabepilone (40 mg/m2 intravenously on day 1) plus capecitabine (2,000 mg/m2 orally on days 1 through 14) or capecitabine alone (2,500 mg/m2 on the same schedule) given every 21 days. The trial was powered to detect a 20% reduction in the hazard ratio (HR) for death. Results There was no significant difference in OS between the combination and capecitabine monotherapy arm, the primary end point (median, 16.4 v 15.6 months; HR = 0.9; 95% CI, 078 to 1.03; P = .1162). The arms were well balanced with the exception of a higher prevalence of impaired performance status (Karnofsky performance status 70% to 80%) in the combination arm (32% v 25%). In a secondary Cox regression analysis adjusted for performance status and other prognostic factors, OS was improved for the combination (HR = 0.85; 95% CI, 0.75 to 0.98; P = .0231). In 79% of patients with measurable disease, the combination significantly improved progression-free survival (PFS; median, 6.2 v 4.2 months; HR = 0.79; P = .0005) and response rate (43% v 29%; P < .0001). Grade 3 to 4 neuropathy occurred in 24% treated with the combination, but was reversible. Conclusion This study confirmed a previous trial demonstrating improved PFS and response for the ixabepilone-capecitabine combination compared with capecitabine alone, although this did not result in improved survival.

Identification of all eligible English trails was made by searching the PubMed and Cochrane databases from 1980 to 2007. Search terms included capecitabine, Xeloda and cancer treatment. Nowadays, FDA has approved the use of capecitabine as a first line therapy in patients with metastatic colorectal cancer when single-agent fluoropyrimidine is preferred. The drug is also approved for use as a single agent in metastatic breast cancer patients who are resistant to both anthracycline and paclitaxel-based regimens or when further anthracycline treatment is contraindicated. It is also approved in combination with docetaxel after failure of prior anthracycline-based chemotherapy. In patients with prostate, pancreatic, renal cell and ovarian carcinomas, capecitabine as a single-agent or in combination with other drugs has also shown benefits. Improved tolerability and comparable efficacy, compared with the intravenous FU/LV combination, in addition to its oral administration, make capecitabine an attractive option for the treatment of several types of carcinomas.

    Purpose: Systemic failure remains the major challenge in management of locally advanced rectal cancer (LARC). To optimize the timing of neoadjuvant treatment and enhance systemic control, we initiated a phase 2 trial to evaluate a new strategy of neoadjuvant sandwich treatment, integrating induction chemotherapy, concurrent chemoradiation therapy, and consolidation chemotherapy. Here, we present preliminary results of this trial, reporting the tumor response, toxicities, and surgical complications. Methods and Materials: Fifty-one patients with LARC were enrolled, among which were two patients who were ineligible because of distant metastases before treatment. Patients were treated first with one cycle of induction chemotherapy consisting of oxaliplatin, 130 mg/m² on day 1, with capecitabine, 1000 mg/m² twice daily for 14 days every 3 weeks (the XELOX regimen), followed by chemoradiation therapy, 50 Gy over 5 weeks, with the modified XELOX regimen (oxaliplatin 100 mg/m²), and then with another cycle of consolidation chemotherapy with the XELOX regimen. Surgery was performed 6 to 8 weeks after completion of radiation therapy. Tumor responses, toxicities, and surgical complications were recorded. Results: All but one patent completed the planned schedule of neoadjuvant sandwich treatment. Neither life-threatening blood count decrease nor febrile neutropenia were observed. Forty-five patents underwent optimal surgery with total mesorectal excision (TME). Four patients refused surgery because of clinically complete response. There was no perioperative mortality in this cohort. Five patients (11.1%) developed postoperative complications. Among the 45 patients who underwent TME, pathologic complete response (pCR), pCR or major regression, and at least moderate regression were achieved in 19 (42.2%), 37 (82.2%), and 44 patients (97.8%), respectively. Conclusions: Preliminary results suggest that the strategy of neoadjuvant sandwich treatment using XELOX regimen

No complete response (CR) cases were observed, but partial response (PR) was achieved in 6 patients (30%) and SD in 9 (45%), of whom 5 (20%) sustained SD status for >12 months. The median TTP was 6 months (range:3-27 mo.). Three patients developed Grade 3 adverse events (diarrhea, nausea and stomatitis), but no other patients developed adverse reactions causing interruption of the therapy. XC was safe even in previously treated and elderly MBC patients;moreover, it yielded remarkable clinical responses.

    Full Text Available The paper considers the experience with capecitabine in 67 patients with brain metastatic lesion from breast cancer. The immediate efficacy of capecitabine and the results of therapy with the agent were analyzed in the groups of its use alone and in combination with radiotherapy both for therapeutic purposes and as an adjuvant regimen. In the chemoradiation therapy group, the objective effects in the brain were 73 %. The median time to progression was 12.27 months. In the monochemotherapy group, the objective effects were 30 %. The median time to progression was 4 months. The results of the investigation show that capecitabine has pronounced antitumor activity and moderate toxicity. Combination treatment is the method of choice.

    Bevacizumab is a humanized monoclonal antibody that inhibits vascular endothelial growth factor, and it has been found to increase both progression-free survival and overall survival when it is combined with chemotherapeutic agents in the first-line and subsequent treatment of metastatic colorectal carcinoma. The objective of this study was to show the efficacy of maintenance treatment with capecitabine plus bevacizumab in patients with metastatic colorectal cancer who responded to treatment with FOLFIRI plus bevacizumab. The study included patients with metastatic colorectal cancer who received FOLFIRI plus bevacizumab as a first-line treatment. Patients who had objective response with FOLFIRI plus bevacizumab treatment after an average period of 6 months received a maintenance treatment with capecitabine plus bevacizumab (capecitabine 2 x 1000 mg/m2, 1 - 14 days, every 21 days, bevacizumab 7.5 mg/m2, every 21 days) until disease progression or toxicity. The time to progression on bevacizumab treatment was evaluated. A total of 29 patients (15 male, 14 female) were included. The mean age was 62 years. The mean number of cycles for maintenance treatment with capecitabine plus bevacizumab was 12. The median PFS was 16 ± 3 months, and OS was 42 ± 11 months. PFS and OS were remarkably higher in patients with a complete or near complete response to induction treatment. Fourteen patients (48%) experienced hand-foot syndrome associated with capecitabine plus bevacizumab treatment, without any severe toxicity. Inselected patients with metastatic colorectal carcinoma who had a remarkable objective response to FOLFIRI plus bevacizumab treatment, a maintenance treatment with capecitabine plus bevacizumab following FOLFIRI plus bevacizumab until disease progression may be a suitable, effective and tolerable regimen, which requires further studies.

  9. Comparison of capecitabine and 5-fluorouracil in chemoradiotherapy for locally advanced pancreatic cancer

    International Nuclear Information System (INIS)

    Although capecitabine has theoretical advantages in the pharmacokinetics, such as higher intratumoral and lower systemic concentration, relative to bolus 5-fluorouracil (5-FU), outcomes of chemoradiotherapy (CRT) with capecitabine or bolus 5-FU have not been directly compared in patients with locally advanced pancreatic cancer. Therefore, we retrospectively compared the outcomes, including toxicity, tumor response, and overall survival, of oral capecitabine plus radiotherapy (RT) with bolus 5-FU plus RT, in patients with locally advanced pancreatic cancer. Between August 2006 and January 2012, 98 patients with locally advanced pancreatic cancer received CRT, with 52 receiving concurrent oral capecitabine and 46 receiving bolus injection of 5-FU. Primary tumor and overall response after CRT were evaluated radiologically, and toxicity, tumor response, and overall survival (OS) were compared in the two groups. Baseline clinical parameters of the two groups were similar. The rates of ≥ Grade 3 hematologic (0% vs. 8.7%, p = 0.045) and non-hematologic (0% vs. 8.7%, p = 0.045) toxicities were significantly lower in the capecitabine group than in the 5-FU group. Primary tumor (30.7% vs. 28.2%, p = 0.658) and overall (13.7% vs. 15.2%, p = 0.273) response rates and median OS time (12.5 months vs. 11.6 months, p = 0.655) were similar in the two groups. Capecitabine plus RT may be a safe and feasible regimen for patients with locally advanced pancreatic cancer, with similar efficacy and low rates of toxicities compared with bolus 5-FU plus RT

Especially when using long-term medication, cancer patients have adherence rates similar to those of patients with other diseases. The consequences of poor adherence are poor health outcomes and increased health care costs. Only few studies have focused on the use of oral anticancer agents in daily practice. Information about the reasons for nonadherence is essential for the development of interventions that may improve adherence. This report presents the CAPER-capecitabine protocol, which is designed to study the adherence to capecitabine and the influence of patient attitudes towards medication and self-reported side effects. Furthermore, the relationships between patient characteristics, disease characteristics, side effects, quality of life, patient beliefs and attitudes towards disease and medication, dose adjustments, reasons for discontinuation, and plasma concentration of three of the main metabolites, including the active compound 5-fluorouracil, will be explored.Methods: In this multicenter, prospective, observational cohort study, 90 patients aged 18 years or older starting treatment with capecitabine will be included and followed for a period up to five cycles. The main study parameters are adherence, patient attitudes towards medication, and the number and grade of patient-reported side effects. At baseline and during week 2 of cycles 1, 3 and 5, patients will be asked to donate blood and fill out a questionnaire. Blood samples will be analyzed for plasma

    Adverse reactions to capecitabine-based chemotherapy limit full administration of cytotoxic agents. Likewise, genetic variations associated with capecitabine-related adverse reactions are associated with controversial results and a low predictive value. Thus, more evidence on the role of these variations is needed. We evaluated the association between nine polymorphisms in MTHFR, CDA, TYMS, ABCB1, and ENOSF1 and adverse reactions, dose reductions, treatment delays, and overall toxicity in 239 colorectal cancer patients treated with capecitabine-based regimens. The ABCB1*1 haplotype was associated with a high risk of delay in administration or reduction in the dose of capecitabine, diarrhea, and overall toxicity. CDA rs2072671 A was associated with a high risk of overall toxicity. TYMS rs45445694 was associated with a high risk of delay in administration or reduction in the dose of capecitabine, HFS >1 and HFS >2. Finally, ENOSF1 rs2612091 was associated with HFS >1, but was a poorer predictor than TYMS rs45445694. A score based on ABCB1-CDA polymorphisms efficiently predicts patients at high risk of severe overall toxicity (PPV, 54%; sensitivity, 43%) in colorectal cancer patients treated with regimens containing capecitabine. Polymorphisms in ABCB1, CDA, ENOSF1,and TYMS could help to predict specific and overall severe adverse reactions to capecitabine. PMID:25691056

    Purpose To determine the maximum tolerated dose (MTD), characterize the principal toxicities, and assess the pharmacokinetics of EKB-569, an oral selective irreversible inhibitor of the epidermal growth factor receptor tyrosine kinase, in combination with capecitabine in patients with advanced colorectal cancer. Experimental Design Patients were treated with EKB-569 daily for 21days and capecitabine twice daily for14 days of a 21-day cycle. The dose levels of EKB-569 (mg/day) and capecitabine (mg/m2 twice daily) assessed were 25/750, 50/750, 50/1,000 and 75/1,000. An expanded cohort was enrolled at the MTD to better study toxicity and efficacy. Samples of plasma were collected to characterize the pharmacokinetics of the agents. Treatment efficacy was assessed every other cycle. Results A total of 37 patients, the majority of whom had prior chemotherapy, received a total of 163 cycles of treatment. Twenty patients were treated at the MTD, 50 mg EKB-569, daily and 1,000 mg/m2 capecitabine twice daily. Dose-limiting toxicities were diarrhea and rash. No patients had complete or partial responses but 48% had stable disease. The conversion of capecitabine to 5-fluorouracil was higher for the combination of EKB-569 and capecitabine (321 ± 151 ng*h/mL) than for capecitabine alone (176 ± 62 ng*hours/mL; P = 0.0037). Conclusion In advanced colorectal cancer, 50 mg EKB-569 daily can be safely combined with 1,000 mg/m2 capecitabine twice a day. A statistically significant increase in plasma levels of 5-fluorouracil for the combination of EKB-569 and capecitabine may be due to the single-dose versus multiple-dose exposure difference, variability in exposure or a potential drug interaction.

    Full Text Available Context Capecitabine has shown efficacy in treatment of metastatic pancreatic cancer. Several researchers have identified thymidine phosphorylase, dihydropyrimidine dehydrogenase, or their ratio as indicators of response to capecitabine in various cancers. Case report We report two patients with metastatic pancreatic carcinoma who had long-term survivals on capecitabine after gemcitabine failure. These two cases prompted us to measure thymidine phosphorylase and dihydropyrimidine dehydrogenase levels to facilitate discourses regarding their relationship with efficacy of capecitabine. We also describe a novel method of measuring thymidine phosphorylase level from serum without an invasive tissue biopsy. One patient is alive as of today, with improved performance status, 50 months after capecitabine was started. CA 19-9 and CT scans remained stable during 57 cycles. Her thymidine phosphorylase level was 1.77 compared to a control level of 1.00. Dihydropyrimidine dehydrogenase level was 4.14 compared to a control level of 1.00. Their ratio was 0.43. The other patient was alive on capecitabine for 24 months. His performance status, bilirubin, AST, and ALT improved on capecitabine. CT scans and CA 19-9 remained stable during this period. He had thymidine phosphorylase level of 5.56, dihydropyrimidine dehydrogenase level of 2.74, and their ratio of 2.03. Conclusion Capecitabine resulted in long term survivals in two patients with metastatic pancreatic cancer after gemcitabine failure. The use of capecitabine as second-line treatment in metastatic pancreatic cancer should be further explored along with the role of thymidine phosphorylase and dihydropyrimidine dehydrogenase levels in its activity. A non-invasive method of thymidine phosphorylase measurement we described should be validated in larger trials.

  15. Preclinical studies of concomitant chemoradiation

    International Nuclear Information System (INIS)

    Animal models are widely used in preclinical studies in order to explain the mechanisms of action of chemotherapy, radiotherapy and concomitant chemoradiation, to analyze pathophysiology of tumors and to evaluate the treatment of choice for malignant tumors. The choice of murine tumor or human tumor xenograft system is still debated. Xenografted human tumors have two main advantages: their human origin and wanted pathological type, which is necessary for future clinical studies. There are a lot of disadvantages of xenografted tumors: the stroma and vascular network of transplanted tumors have murine origin, the graft is mostly ectopic, the volume of transplanted tumors at the time of chemoradiotherapy is much smaller than that of the tumor in man; due to residual immunity it is difficult to determine response to cytotoxic treatment. It is still impossible to extrapolate the results obtained in a tumor model in animal to man. These investigations are useful for interpretation of clinical results and for proposing the less empirical method of chemoradiation for phase II clinical trials. (author)

    Objective The aim of the study was to evaluate the safety and ef icacy of capecitabine mono-chemo-therapy in elderly patients with advanced breast cancer. Methods The data from 36 cases of capecitabine monotherapy in elderly patients with advanced breast cancer were retrospectively analyzed. Oral administration of capecitabine 2000 mg/m2 twice daily (D1–14) for 21 days constituted a cycle. The ef ect of the disease and main adverse reactions were evaluated every 2 cycles. Results The data from 36 elderly patients were studied. The median number of chemotherapy cycles was 4. The total ef ective rate was 30.6% (11/36) and the disease control rate was 72.2% (26/36). The number of patients with clinical complete remission was 2, clinical partial response was 9, stable disease was 15, and progressive disease was 10. Where treatment was ef ective, the median time to progression was 6 months and the median overal survival was 9.5 months. The main adverse events were gastroin-testinal reactions, bone marrow suppression, and oral mucositis; most of the reactions were grade 1 to 2. Grade 3 to 4 adverse reactions included granulocytopenia in 2 patients (12.5%) and hand-foot syndrome in 1 patient (6.7%). Conclusion Capecitabine monotherapy was ef ective in control ing disease progression, and adverse reactions were tolerated by elderly patients with advanced breast cancer.

    Full Text Available Context Capecitabine, an oral drug, is as effective as traditional chemotherapy drugs. Objectives To investigate the adhesion to treatment with oral capecitabine in breast and colorectal cancer, and to determine any correlation with changes in patient’s quality of life. Methods Patients with colorectal cancer or breast cancer using capecitabine were included. The patients were asked to bring any medication left at the time of scheduled visits. The QLQ-C30 questionnaire was applied at the first visit and 8-12 weeks after treatment. Results Thirty patients were evaluated. Adherence was 88.3% for metastatic colon cancer, 90.4% for non-metastatic colon cancer, 94.3% for rectal cancer and 96.2% for metastatic breast cancer. No strong correlation between adherence and European Organisation for Research and Treatment of Cancer QLQ-C30 functional or symptom scale rates had been found. There was no statistically significant correlation between compliance and the functional and symptom scales of the questionnaire before and after chemotherapy, with the exception of dyspnea. Conclusions Although no absolute adherence to oral capecitabine treatment had been observed, the level of adherence was good. Health professionals therefore need a greater focus in the monitoring the involvement of patients with oral treatment regimens. Patients with lesser degrees of dyspnea had greater compliance.

    Purpose To define maximum tolerated dose (MTD), toxicities, and pharmacodynamics of capecitabine, oxaliplatin, bevacizumab, and everolimus in advanced solid tumor patients. Design This was a standard “3+3” dose-escalation trial. All subjects received bevacizumab 7.5mg/kg on day one of each cycle. Doses for capecitabine, oxaliplatin and everolimus were modified per dose limiting toxicity (DLT). Baseline and on-treatment plasma biomarkers were analyzed. Archived tumor mRNA levels were evaluated for NRP1, NRP2 and VEGF-A isoforms. Results Twenty-nine patients were evaluable for toxicity and 30 for efficacy. Two DLTs were observed in cohort 1 and one DLT each was observed in cohort -1 and -1b. Grade ≥3 toxicities included neutropenia, hypertension, perforation/fistula/hemorrhage, hypertriglyceridemia, diarrhea, and thromboembolism. Twelve subjects experienced partial response (PR); 12 had stable disease as best response. Three of seven chemorefractory metastatic colorectal cancer (mCRC) subjects experienced PR; eight of 15 chemonaive mCRC subjects experienced PR. Plasma TβRIII and IL-6 increased on treatment but without correlation to outcome. Increased VEGF165 levels significantly correlated with longer progression free survival. Conclusions Everolimus with full dose capecitabine, oxaliplatin, and bevacizumab had unacceptable toxicity. MTD was: everolimus 5mg daily; capecitabine 680mg/m2 BID days 1-14; oxaliplatin 100mg/m2 and bevacizumab 7.5mg/kg, day one. Activity was noted in mCRC. PMID:24711126

    Full Text Available Abstract Introduction We report a case of stage IV breast cancer terminating in an unusual picture of radiologically occult micronodular pseudo-cirrhosis. Contrast-enhanced computed tomography showed no evidence of metastatic breast cancer within the liver. Unlike the few previously reported cases of intrasinusoidal spread of breast cancer, our patient was palliated with a transjugular intrahepatic portosystemic shunt along with salvage chemohormonal therapy. In addition, our patient demonstrated proof of the principle of the dependence of capecitabine (Xeloda efficacy on dose scheduling as predicted by laboratory studies based on Gompertzian tumor growth and the Norton-Simon hypothesis. Case presentation We report the case of a 52-year-old Caucasian woman who developed radiological signs of portal hypertension without radiological evidence of hepatic metastasis five years after being diagnosed with metastatic breast cancer. She was receiving chemotherapy for stage IV breast cancer initially thought to be metastatic only to the bones. During salvage therapy with high-dose estradiol (Estradiol valerate, vinorelbine (Navelbine and bevacizumab (Avastin, she suddenly developed signs of portal hypertension confirmed on computed tomography and by portal and systemic venous pressure measurements. Drug toxicity due to bevacizumab (Avastin was initially and incorrectly entertained as a cause. The patient underwent palliative transjugular intrahepatic portosystemic shunt and transhepatic venous liver biopsy, which revealed the presence of rapidly progressive and uncontrolled metastatic breast cancer. The new discovery of radiologically occult intrasinusodal hepatic metastases with secondary micronodular cirrhosis was found to be the cause of her sudden onset portal hypertension. The patient's resistance to capecitabine (Xeloda was reversed by changing the schedule of medication to biweekly 7/7 (7 days ingesting drug alternating with 7 days off drug from

    Neuroendocrine tumors are a rare and heterogeneous group of tumors with a variety of primary origins and variable aggressiveness. Platinum-based chemotherapy has been the cornerstone of treatment for the poorly differentiated tumors. However, well-differentiated neuroendocrine tumors are quite chemoresistant and therapy options are limited. Octreotide analogs and tyrosine kinase inhibitors are widely acceptable treatments due to substantial efficacy and tolerable toxicity. On the contrary, monotherapy or combinations of the only approved cytotoxic agent streptozocin with other drugs have been almost abandoned because of excessive toxic events. In recent years, the combination of capecitabine and temozolomide has emerged as the most promising and efficacious treatment. The oral route of administration and the substantial improvement in the outcomes with manageable toxicity are the major advantages. We reviewed the current literature and presented the profile of the capecitabine/temozolomide combination in the management of well-differentiated neuroendocrine tumors. PMID:26929640

In recent years, the incidence of this side effect has increased and it is expected to further rise due to the population aging and the disproportionate incidence of breast and gastrointestinal cancers in older individuals. The spectrum of cardiac manifestations includes different signs and symptoms and the diagnosis may be difficult. Here, we report the case of a 43-year-old woman with advanced breast cancer who was rechallenged with a capecitabine-based regimen after experiencing a cardiac adverse event during the first fluoropyrimidine exposure. This real-practice case serves as a springboard for discussion about the current evidence on differential diagnosis of capecitabine-related cardiac toxicity, its risk factors, and the underpinning mechanisms of early onset. Moreover, we discussed whether a rechallenge with fluoropyrimidines could be safe in patients who had experienced a previous cardiac adverse event.

    Background There are no data on more tolerable capecitabine doses in elderly patients in Chinese population. The aim of this study was to evaluate the activity and safety of capecitabine combined with weekly docetaxel for the treatment of anthracycline-resistant metastatic breast cancer (MBC) in older Chinese patients.Methods MBC patients aged >65 years pretreated with 1-5 prior chemotherapy regimens, including an anthracycline,received oral capecitabine 825 mg/m2 twice daily, days 1-14, plus docetaxel30 mg/m2 on days 1 and 8 every 21 days. All 41 enrolled patients received at least 1 dose of treatment and were evaluable for safety; 38 received at least 2 cycles (median 4, range 2-8) and were evaluable for efficacy.Results The overall objective response rate was 47%, including complete responses in 8% of patients. Median time to progression was 8.9 months. Median overall survival was 17.6 months. The most common side effects were haematological and gastrointestinal toxicities and hand-foot syndrome. The only grade 3/4 adverse events were neutropenia (12%), alopecia (7%), grade 3 nausea and vomiting (2%) and grade 3 nail toxicity (2%).Conclusions Capecitabine 825 mg/m2 twice daily plus weekly docetaxel is active with an acceptable safety profile in Chinese women >65 years with anthracycline-resistant MBC. Efficacy and tolerability compare favourably with previously reported trials evaluating higher capecitabine doses in combination with 3-weekly or weekly docetaxel.

Methods and Materials: A randomized, phase 2 trial evaluated preoperative RT (50.4 Gy in 1.8-Gy fractions) with 2 concurrent chemotherapy regimens: (1) capecitabine (1200 mg/m2/d Monday-Friday) plus irinotecan (50 mg/m2/wk × 4); and (2) capecitabine (1650 mg/m2/d Monday-Friday) plus oxaliplatin (50 mg/m2/wk × 5) for clinical T3 or T4 rectal cancer. Surgery was performed 4 to 8 weeks after chemoradiation, then 4 to 6 weeks later, adjuvant chemotherapy (oxaliplatin 85 mg/m2; leucovorin 400 mg/m2; 5-fluorouracil 400 mg/m2; 5-fluorouracil 2400 mg/m2) every 2 weeks × 9. Disease-free survival (DFS) and overall survival (OS) were estimated univariately by the Kaplan-Meier method. Local–regional failure (LRF), distant failure (DF), and second primary failure (SP) were estimated by the cumulative incidence method. No statistical comparisons were made between arms because each was evaluated individually. Results: A total of 104 patients (median age, 57 years) were treated; characteristics were similar for both arms. Median follow-up for RT with capecitabine/irinotecan arm was 3.77 years and for RT with capecitabine/oxaliplatin arm was 3.97 years. Four-year DFS, OS, LRF, DF, and SP estimates for capecitabine/irinotecan arm were 68%, 85%, 16%, 24%, and 2%, respectively. The 4-year DFS, OS, LRF, DF, and SP failure estimates for capecitabine/oxaliplatin arm were 62%, 75%, 18%, 30%, and 6%, respectively. Conclusions: Efficacy results for both arms are similar to other reported studies but suggest that pathologic complete remission is an unsuitable surrogate for traditional survival

  4. Phase I study of intermittent and chronomodulated oral therapy with capecitabine in patients with advanced and/or metastatic cancer

    International Nuclear Information System (INIS)

    The combination of capecitabine and gemcitabine at Fixed Dose Rate (FDR) has been demonstrated to be well tolerated, with apparent efficacy in patients with advanced cancers. FDR gemcitabine infusion leads to enhanced intracellular accumulation of drug and possible augmented clinical effect. The goals of this phase I study were to determine the maximum-tolerated dose (MTD) of chronomodulated capecitabine in patients with advanced cancer and to describe the dose-limiting toxicities (DLT), the safety profile of this way of administration. Patients with advanced solid tumours who had failed to response to standard therapy or for whom no standard therapy was available were elegible for this study. Capecitabine was administered orally according to following schedule: 1/4 of dose at 8:00 a.m.; 1/4 of dose at 6:00 p.m. and 1/2 of dose at 11:00 p.m. each day for 14 consecutive days, followed by a 7-day rest period. All 27 patients enrolled onto the study were assessable for toxicity. The most common toxicities during the first two cycles of chemotherapy were fatigue, diarrhoea and hand foot syndrome (HFS). Only one out of the nine patients treated at capecitabine dose of 2,750 mg/m2 met protocol-specified DLT criteria (fatigue grade 4). However, at these doses the majority of cycles of therapy were delivered without dose reduction or delay. No other episodes of DLT were observed at the same dose steps and at the lower dose steps of capecitabine (1,500/1,750/2,000/2,250/2,500 mg/m2). The dose of 2,750 mg/m2 is recommended for further study. Tumor responses were observed in patients with metastatic breast and colorectal cancer. High doses of chronomodulated capecitabine can be administered with acceptable toxicity. The evidence of antitumor activity deserves further investigation in phase II combination chemotherapy studies

    Treatment of patients with carcinoma of unknown primary site (CUP) remains a challenge, and no effective second-line treatment has been identified. In CUP patients who are non-responsive or relapse early after first-line platinum/taxane-based regimens, it is likely that gastrointestinal (GI) tract...... tumours may be overrepresented. These patients could be candidates for GI tract-directed therapy. We here report the results obtained with oxaliplatin and capecitabine as second-line therapy in 25 recurrent/refractory CUP patients following first-line treatment with paclitaxel, cisplatin and gemcitabine....

  8. Clinical efficacy of including capecitabine in neoadjuvant chemotherapy for breast cancer: a systematic review and meta-analysis of randomized controlled trials.

    Qiuyun Li

    Full Text Available BACKGROUND: Capecitabine has proven effective as a chemotherapy for metastatic breast cancer. Though several Phase II/III studies of capecitabine as neoadjuvant chemotherapy have been conducted, the results still remain inconsistent. Therefore, we performed a meta-analysis to obtain more precise understanding of the role of capecitabine in neoadjuvant chemotherapy for breast cancer patients. METHODS: The electronic database PubMed and online abstracts from ASCO and SABCS were searched to identify randomized clinical trials comparing neoadjuvant chemotherapy with or without capecitabine in early/operable breast cancer patients without distant metastasis. Risk ratios were used to estimate the association between capecitabine in neoadjuvant chemotherapy and various efficacy outcomes. Fixed- or random-effect models were adopted to pool data in RevMan 5.1. RESULTS: Five studies were included in the meta-analysis. Neoadjuvant use of capecitabine with anthracycline and/or taxane based therapy was not associated with significant improvement in clinical outcomes including: pathologic complete response in breast (pCR; RR = 1.10, 95% CI 0.87-1.40, p = 0.43, pCR in breast tumor and nodes (tnpCR RR = 0.99, 95% CI 0.83-1.18, p = 0.90, overall response rate (ORR; RR = 1.00, 95% CI 0.94-1.07, p = 0.93, or breast-conserving surgery (BCS; RR = 0.98, 95% CI 0.93-1.04, p = 0.49. CONCLUSIONS: Neoadjuvant treatment of breast cancer involving capecitabine did not significantly improve pCR, tnpCR, BCS or ORR. Thus adding capecitabine to neoadjuvant chemotherapy regimes is unlikely to improve outcomes in breast cancer patients without distant metastasis. Further research is required to establish the condition that capecitabine may be useful in breast cancer neoadjuvant chemotherapy.

    Full Text Available David B. Smith1, John P. Neoptolemos21Clatterbridge Centre for Oncology, Bebington, Wirral, UK; 2School of Cancer Studies, University of Liverpool, Liverpool, UKIntroduction: More than 90% of patients with pancreatic cancer present either with incurable locally advanced or metastatic disease or relapse following surgery. For these patients systemic therapy offers the only prospect of salvage, but pancreatic cancer is one of the most chemoresistant of tumors; current chemotherapy can only delay progression in a limited proportion of patients and survival rates are poor. There is therefore a pressing need for more effective therapy. Capecitabine is a new oral prodrug of fluorouracil, which has shown activity in pancreatic cancer particularly when used in combination with gemcitabine.Aims: To review the emerging evidence for the clinical effectiveness of capecitabine in the management of carcinoma of the pancreas.Evidence review: There is evidence from phase II testing that capecitabine is active in pancreatic cancer. The Swiss Group for Clinical Cancer Research/Central European Cooperative Oncology Group (SAKK/CECOG phase III trial found that the combination of gemcitabine and capecitabine did not improve overall median survival as compared with gemcitabine alone (8.4 vs 7.3 months, respectively; P=0.314 but subgroup analysis in patients with good performance score [Karnofsky Performance Scores (KPS ³90] revealed a significant survival improvement with the combination arm (10.1 months compared with single-agent gemcitabine (7.5 months; P=0.033.

He underwent potential curative surgery for medullary thyroid carcinoma, 3 years ago and then 7 months later he had metastasectomy and cervical lymph node dissection for recurrent disease. On admission he had multiple metastatic skin nodules on the chest wall and positron emission tomography–computed tomography revealed multiple visceral metastases as well. The patient had not received any systemic treatment up to that time; therefore, we considered systemic treatment with the new tyrosine kinase inhibitors (vandetanib, cabozantinib, etc. However, since these drugs are only available after cytotoxic chemotherapy, we started temozolomide and capecitabine chemotherapy. After two courses of the treatment all skin nodules disappeared and CEA and calcitonin levels normalized, radiological imaging showed a good partial response.

    The use of anticancer drugs in palliative settings is often limited by their severe toxic effects. In gastrointestinal carcinomas the 5-fluorouracil-based palliative regimen FOLFOX-4 is often preferred to the equally effective, but more convenient oral capecitabine-based regimen XELOX. This preference is mainly based on the fact that the highly effective oral agent capecitabine induces hand-foot syndrome (HFS). In this study, we investigated whether the continuous administration of skin proph...

    Oral capecitabine (Xeloda®) is an effective drug with favourable safety in adjuvant and metastatic colorectal cancer. Oxaliplatin-based therapy is becoming standard for Dukes' C colon cancer in patients suitable for combination therapy, but is not yet approved by the UK National Institute for Health and Clinical Excellence (NICE) in the adjuvant setting. Adjuvant capecitabine is at least as effective as 5-fluorouracil/leucovorin (5-FU/LV), with significant superiority in relapse-free sur...

  18. Genomic alterations in DNA repair and chromatin remodeling genes in estrogen receptor-positive metastatic breast cancer patients with exceptional responses to capecitabine

    International Nuclear Information System (INIS)

    We analyzed the genomic and phosphoproteomic profiles of breast cancer tissue obtained from six patients with estrogen receptor (ER)-positive, HER2-negative metastatic breast cancer who had highly durable (≥5 years) and, in some cases, ongoing clinical responses with capecitabine. Formalin-fixed, paraffin-embedded tissue samples from patients’ primary (n = 4) or metastatic (n = 2) breast cancers were utilized for targeted next-generation sequencing and reversed phase protein microarray. Two patients received capecitabine monotherapy. Four patients received capecitabine in combination with paclitaxel; three of these continued single-agent capecitabine after stopping paclitaxel. Capecitabine was discontinued for progressive disease after a mean of 66 months in four patients (range 54–86 months), and two patients remain on therapy, having received capecitabine for >91 months and >122 months, respectively. Three patients’ cancers (50%) had likely functional alterations in DNA repair and chromatin remodeling genes, while three other patients’ cancers had variants of unknown significance in these pathways. Mutations in PIK3CA, amplifications of FGFR1 or ZNF703, or phosphorylation of HER family receptors and their downstream proteins did not preclude exceptional responses to capecitabine. None of the patients’ tumors harbored TP53 or PTEN mutations. Four of the patients had breast cancer tissue available for PTEN immunohistochemistry, and all four patients’ cancers were positive for PTEN. These surprising findings in a group of phenotypically similar patients with ER-positive, endocrine therapy-pretreated, HER2-negative metastases, are supported by preclinical data showing that sensitivity to 5-fluorouracil is enhanced by deficiencies in chromatin remodeling and homologous recombination genes. Our findings suggest that mutations that inactivate homologous recombination and/or chromatin remodeling genes within ER-positive, HER2-negative breast cancers may

  19. Concomitant pituitary adenoma and Rathke's cleft cyst

    International Nuclear Information System (INIS)

    We reviewed the clinical, radiological and surgical findings in patients with both pituitary adenoma and Rathke's cleft cyst. We retrospectively selected patients with both lesions from the 374 patients in whom a sellar/juxtasellar lesion was detected on MRI at 1.5 tesla. All patients received intravenous contrast medium. Concomitant pituitary adenoma and Rathke's cleft cyst were found in eight patients (2.1 %). The frequency of the combination was 3.5 % of pituitary adenomas and 11 % of Rathke's cleft cysts. Symptoms were always due to the adenoma, secreting adrenocorticotrophin in two patients and growth hormone in six. The adenoma was larger in five patients, and the cyst in three. The cysts gave variable signal. The adenoma was adjacent to the cyst in seven patients, and enclosed it in the other patient. As a result of experience with MRI, concomitant pituitary adenoma and Rathke's cleft cyst are now known not to be as rare as thought previously. When a nonenhancing cyst-like structure is demonstrated in a patient with pituitary adenoma, the possibility of a coexisting Rathke's cleft cyst should be considered. (orig.)

  20. Superselective arterial infusion and concomitant radiotherapy

    International Nuclear Information System (INIS)

    Superselective arterial infusion for patients with advanced head and neck cancer has been increasingly applied in Japan. We analyzed our experiences and evaluated the efficacy and safety of this treatment. Through October 1999 to March 2002, 29 patients, ranging in age between 33 and 71 years (median 52 years), received superselective intra-arterial infusion therapy of cisplatin (100-120 mg/m2/week) with simultaneous intravenous infusion of thiosulfate for neutralizing cisplatin toxicity, and conventional concomitant extrabeam radiotherapy (65 Gy/26 f/6.5 weeks). Four patients were diagnosed with stage III and 25 with stage IV. Thirteen patients were considered contraindicated for surgery, and the other 16 patients rejected radical surgery. Primary tumor sites included paranasal sinus (11 patients), hypopharynx (7), oropharynx (6), oral cavity (4), and parotid gland (1). During the median follow-up period of 20 months, there was no apparent recurrence in 14 (48.3%) of 29 patients. Eleven (37.9%) patients died of disease, and three (10.3%) were alive with disease. In twenty-one patients (72.4%) the primary lesions were well-controlled. Acute toxic effects were moderate, and severe toxic events occurred in four cases, namely, methicillin-resistant staphylococcus aureus (MRSA) pneumonia, sepsis, tetraplasia, and osteoradionecrosis. We confirmed the effectiveness and safety of superselective arterial infusion and concomitant radiotherapy. Furthermore, we must establish the optimal procedures and schedule, as well as the indications for this treatment. This treatment protocol may improve the prognosis of patients with unresectable disease and patients rejecting surgical treatment. Further study in this particular area is needed. (author)

    Full Text Available Pancreatic neuroendocrine tumors (PNETs are relatively rare tumors that arise in the endocrine cells of the pancreas. Historically, somatostatin analogues have been used in this disease primarily for symptom control and, to a limited extent, disease stability. More recently, sunitinib and everolimus have been approved for advanced stage PNETs based on a survival benefit. However, both agents have a <10% actual response rate and cause nontrivial side effect profiles that limit duration of therapy. In locally advanced disease, there is a paucity of data to support an optimal neoadjuvant approach with the expectation of down-staging to allow for curative resection. We describe in this case a young woman who was successfully down-staged using a chemotherapy regimen of capecitabine and temozolomide with minimal toxicity.

    Full Text Available BACKGROUND: Capecitabine is effective and indicated for the salvage treatment of metastatic breast cancer. Therefore, it is essential to evaluate the efficacy of capecitabine in the adjuvant setting. There have been two large randomized studies to determine whether patients with high-risk early breast cancer benefit from the addition of capecitabine to standard chemotherapy, but they have yielded inconsistent results. We first undertook a meta-analysis to evaluate the efficacy of the addition of capecitabine over standard treatment. METHODS: PubMed, EBSCO, Web of Science, conference proceedings and key trials were searched from 1998 to 2011. The hazard ratio (HR was used to evaluate the efficacy of a taxane-anthracycline regimen and a taxane-anthracycline-capecitabine regimen in early breast cancer. All of the data from each study use either fixed-effects or random-effects by Stata. FINDINGS: We found significant improvement in the additional capecitabine arm versus control in disease-free survival (DFS (HR = 0.83, 95% CI: 0.71-0.98, P = 0.027, overall survival (OS (HR = 0.71, 95% CI: 0.57-0.88, P = 0.002, distant recurrence (HR = 0.79, 95% CI: 0.66-0.94, P = 0.008 and the death from breast cancer only (HR = 0.65, 95% CI: 0.51-0.83, P = 0.001. Meanwhile, the subgroup analysis revealed that capecitabine improved the DFS in triple negative (HR = 0.71, 95% CI: 0.53-0.96, P = 0.028, hormone receptor negative (HR = 0.73, CI: 0.56-0.94, P = 0.017 and HER2 negative (HR = 0.81, CI: 0.67-0.98, P = 0.034 patients. CONCLUSION: Due to the synergistic effect of taxane and capecitabine, taxane-anthracycline-capecitabine regimen may effectively improve the efficacy in the adjuvant setting and may be a novel generation of adjuvant chemotherapy regimen. The results of the current meta-analysis support this hypothesis and indicate that taxane-based regimen with capecitabine may be an effective, convenient

    AIM: To investigate the efficacy and safety of capecitabine plus irinotecan ± bevacizumab in advanced or metastatic colorectal cancer patients.METHODS: Forty six patients with previously untreated,locally-advanced or metastatic colorectal cancer (mCRC) were recruited between 2001-2006 in a prospective open-label phase Ⅱ trial, in German community-based outpatient clinics. Patients received a standard capecitabine plus irinotecan (CAPIRI) or CAPIRI plus bevacizumab (CAPIRI-BEV) regimen every 3 wk.Dose reductions were mandatory from the first cycle in cases of > grade 2 toxicity. The treatment choice of bevacizumab was at the discretion of the physician. The primary endpoints were response and toxicity and secondary endpoints included progression-free survival and overall survival.RESULTS: In the CAPIRI group vs the CAPRI-Bev group there were more female than male patients (47%vs 24%), and more patients had colon as the primary tumor site (58.8% vs 48.2%) with fewer patients having sigmoid colon as primary tumor site (5.9% vs20.7%). Grade 3/4 toxicity was higher with CAPIRI than CAPIRI-Bev: 82% vs 58.6%. Partial response rates were 29.4% and 34.5%, and tumor control rates were 70.6% and 75.9%, respectively. No complete responses were observed. The median progression-free survival was 11.4 mo and 12.8 mo for CAPIRI and CAPIRI-Bev, respectively. The median overall survival for CAPIRI was 15 mo (458 d) and for CAPIRI-Bev 24 mo (733 d). These differences were not statistically different.In the CAPIRI-Bev, group, two patients underwenta full secondary tumor resection after treatment,whereas in the CAPIRI group no cases underwent this procedure.CONCLUSION: Both regimens were well tolerated and offered effective tumor growth control in this outpatient setting. Severe gastrointestinal toxicities and thromboembolic events were rare and if observed were never fatal.

    {sup 188}Re-HEDP is indicated for the treatment of pain in patients with painful osteoblastic bone metastases, including hormone-refractory prostate cancer patients. Efficacy may be improved by adding chemotherapy to the treatment regimen as a radiation sensitizer. The combination of {sup 188}Re-HEDP and capecitabine (Xeloda registered) was tested in a clinical phase I study. Patients with hormone-refractory prostate cancer were treated with capecitabine for 14 days (oral twice daily in a dose escalation regimen with steps of 1/3 of 2,500 mg/m{sup 2} per day in cohorts of three to six patients, depending on toxicity). Two days later patients were treated with 37 MBq/kg {sup 188}Re-HEDP as an intravenous injection. Six hours after treatment post-therapy scintigraphy was performed. Urine was collected for 8 h post-injection. Follow-up was at least 8 weeks. The primary end-point was to establish the maximum tolerable dose (MTD) of capecitabine when combined with {sup 188}Re-HEDP. Secondary end-points included the effect of capecitabine on the biodistribution and pharmacokinetics of {sup 188}Re-HEDP. Three patients were treated in the first and second cohorts, each without unacceptable toxicity. One of six patients in the highest cohort experienced unacceptable toxicity (grade 4 thrombopaenia). The MTD proved to be the maximum dose of 2,500 mg/m{sup 2} per day capecitabine. No unexpected toxicity occurred. Capecitabine had no effect on uptake or excretion of {sup 188}Re-HEDP. Capecitabine may be safely used in combination with {sup 188}Re-HEDP in a dose of 2,500 mg/m{sup 2} per day and 37 MBq/kg, respectively. Efficacy will be further studied in a phase II study using these dosages. (orig.)

    The FDA-approved starting dosage of capecitabine is 1,250 mg/m(2), and market research indicates that U.S. physicians routinely prescribe 1,000 mg/m(2). Retrospective analyses however report reduced toxicity and efficacy in a subset of patients with the 3R/3R genotype of the thymidylate synthase gene enhancer region (TSER). This study sought to develop TSER genotype-specific guidelines for capecitabine dosing. Capecitabine was dose-escalated in advanced and/or metastatic cancer patients with TSER 3R/3R (Group A; N = 18) or 2R/2R + 2R/3R (Group B; N = 5) from 1,250 to 1,625 mg/m(2) b.i.d., every 2 weeks on/1 week off for up to 8 cycles. Parent and metabolites pharmacokinetics, adverse events, and tumour response were assessed. The maximum tolerated and recommended doses in 3R/3R patients are 1,625 mg/m(2) and 1,500 mg/m(2). At 1,500 mg/m(2), one in nine 3R/3R patients experienced a dose-limiting toxicity. Dosing guidelines for 2R/2R + 2R/3R remain undetermined due to poor accrual. The results indicate that 3R/3R patients may be amenable to 1,500 mg/m(2) b.i.d. on an intermittent schedule, and is the first to prospectively validate the utility of TSER pharmacogenetic-testing before capecitabine treatment.

    Full Text Available ABSTRACT: The goal of the present study was to investigate the feasibility of using non-ionic surfactant vesicles as carriers for the sustained delivery of water soluble anti-cancer drug Capecitabine, used in the treatment of colorectal cancer. The niosomal formulations were prepared using various non-ionic surfactants (span 40, span 60, tween 40 and tween 60 in the presence of cholesterol, by thin film hydration technique. The effect of process related variables like hydration time, sonication time, rotation speed of evaporation flask on the entrapment efficiency and in vitro drug release were evaluated. Formulation of Capecitabine niosomes was optimized by altering the proportions of Tween, Span and cholesterol. The formation, morphology and size of the drug loaded niosomes were determined by optical microscopy, transmission electron microscopy and particle size analyzer respectively. Results showed a substantial change in the release rate and in the % Entrapment of Capecitabine from niosomal formulations upon varying the type of surfactant and cholesterol content. In-vitro drug release results confirmed that the niosomal formulations have exhibited a higher retention of Capecitabine inside the vesicles such that the in-vitro release was slower compared to the drug solution. Highest drug entrapment (59.1±0.72% and sustained release (67.95±0.65% was obtained with vesicles formed using tween 60 and cholesterol in 4:1 ratio. The optimized niosomal formulation was subjected to stability studies at 4±2°C and 27±2°C for a period of three months.

    PURPOSE AND METHODS Our secondary analyses compared survival with eribulin versus capecitabine in various patient subgroups from a phase 3, open-label, randomized study. Eligible women aged ≥18 years with advanced/metastatic breast cancer and ≤3 prior chemotherapies (≤2 for advanced/metastatic disease), including an anthracycline and taxane, were randomized 1:1 to intravenous eribulin mesylate 1.4 mg/m2 on days 1 and 8 or twice-daily oral capecitabine 1250 mg/m2 on days 1–14 (21-day cycles). RESULTS In the intent-to-treat population (eribulin 554 and capecitabine 548), overall survival appeared longer with eribulin than capecitabine in various subgroups, including patients with human epidermal growth factor receptor 2-negative (15.9 versus 13.5 months, respectively), estrogen receptor-negative (14.4 versus 10.5 months, respectively), and triple-negative (14.4 versus 9.4 months, respectively) disease. Progression-free survival was similar between the treatment arms. CONCLUSIONS Patients with advanced/metastatic breast cancer and human epidermal growth factor receptor 2-, estrogen receptor-, or triple-negative disease may gain particular benefit from eribulin as first-, second-, and third-line chemotherapies. TRIAL REGISTRATION (PRIMARY STUDY) This study reports the subgroup analyses of eribulin versus capecitabine from a phase 3, open-label, randomized study (www.clinicaltrials.gov; ClinicalTrials.gov identifier: NCT00337103).

    Full Text Available Shailendra KapoorRichmond, VA, USAI read with great interest the recent article by Hameed et al in a recent issue of your journal.1 The article is very interesting. Interestingly, the past few years have seen the emergence of capecitabine as a highly potent first-line chemotherapeutic agent against advanced systemic carcinomas other than colorectal carcinoma. For instance, capecitabine has recently been used successfully as a first-line monotherapeutic agent for HER-2-negative metastatic breast cancer.2 Cotherapy with agents such as sorafenib and paclitaxel for HER-2-negative metastatic breast cancer has also been recently used first-line, and significantly improves progressionfree survival, in addition to being very safe.3,4 Similarly, in patients with advanced gastric carcinoma, capecitabine has been used successfully as first-line therapy in combination with agents such as cisplatin.5 The XELOX regimen comprising capecitabine in conjunction with oxaliplatin is another recent highly effective alternative for gastric carcinoma.6 The modified XELIRI regimen compromising capecitabine and irinotecan is a further option for advanced and unresectable gastric carcinoma.7View original paper by Hameed and colleagues.

Here, we report on a case of isolated para-aortic lymph node metastasis from rectosigmoid cancer that showed complete response to chemoradiation therapy with capecitabine/oxaliplatin plus bevacizumab. A 58-year-old woman underwent high anterior resection for rectosigmoid cancer in 2009. Para-aortic lymph node recurrence occurred in 2011. She underwent radiation therapy (50 Gy) and 8 courses of capecitabine/oxaliplatin plus bevacizumab. Abdominal computed tomography and positron emission tomography with 18-fluorodeoxyglucose did not reveal any para-aortic lymph node recurrence after chemoradiation therapy. Hence, this case was interpreted as a complete response. No recurrence was noted 6 months after the complete response. Chemoradiation therapy with capecitabine/oxaliplatin plus bevacizumab is likely to be effective in treating patients with para-aortic lymph node recurrence.

    Full Text Available OBJECTIVE: The aim of this paper was to compare the efficacy and safety of S-1-based and capecitabine-based preoperative chemoradiotherapy regimens in patients with locally advanced rectal cancer through a retrospective matched-pair analysis. MATERIALS AND METHODS: Between Jan 2010 and Mar 2014, 24 patients with locally advanced rectal cancer who received preoperative radiotherapy concurrently with S-1 were individually matched with 24 contemporary patients with locally advanced rectal cancer who received preoperative radiotherapy concurrently with capecitabine according to clinical stage (as determined by pelvic magnetic resonance imaging and computed tomography and age (within five years. All these patients performed mesorectal excision 4-8 weeks after the completion of chemoradiotherapy. RESULTS: The tumor volume reduction rates were 55.9±15.1% in the S-1 group and 53.8±16.0% in the capecitabine group (p = 0.619. The overall downstaging, including both T downstaging and N downstaging, occurred in 83.3% of the S-1 group and 70.8% of the capecitabine group (p = 0.508. The significant tumor regression, including regression grade I and II, occurred in 33.3% of S-1 patients and 25.0% of capecitabine patients (p = 0.754. In the two groups, Grade 4 adverse events were not observed and Grade 3 consisted of only two cases of diarrhea, and no patient suffered hematologic adverse event of Grade 2 or higher. However, the incidence of diarrhea (62.5% vs 33.3%, p = 0.014 and hand-foot syndrome (29.2% vs 0%, p = 0.016 were higher in capecitabine group. Other adverse events did not differ significantly between two groups. CONCLUSIONS: The two preoperative chemoradiotherapy regimens were effective and safe for patients of locally advanced rectal cancer, but regimen with S-1 exhibited a lower incidence of adverse events.

    Full Text Available PURPOSE: Oral fluoropyrimidine (S-1, capecitabine has been considered as an important part of various regimens. We aimed to evaluate the efficacy and safety of S-1-based therapy versus capecitabine -based therapy in gastrointestinal cancers. METHODS: Eligible studies were identified from Pubmed, EMBASE. Additionally, abstracts presented at American Society of Clinical Oncology (ASCO conferences held between 2000 and 2013 were searched to identify relevant clinical trials. The outcome included overall survival (OS, progression-free survival (PFS, overall response rate (ORR, disease control rate (DCR and advent events. RESULTS: A total of 6 studies (4 RCTs and 2 retrospective analysis studies containing 790 participants were included in this meta-analysis, including 401 patients in the S-1-based group and 389 patients in the capecitabine-based group. Results of our meta-analysis indicated that S-1-based and capecitabine-based regimens showed very similar efficacy in terms of PFS (HR 0.92, 95% CI 0.78-1.09, P = 0.360, OS (HR 1.01, 95% CI 0.84-1.21, P = 0.949, ORR (HR 1.04, 95% CI 0.87-1.25, P = 0.683 and DCR (HR 1.02, 95% CI 0.94-1.10, P = 0.639. There was also no significant difference in toxicity between regimens other than mild more hand-foot syndrome in capecitabine-based regimens. CONCLUSION: Both the S-1-based and capecitabine-based regimens are equally active and well tolerated, and have the potential of backbone chemotherapy regimen in further studies of gastrointestinal cancers.

    Brain metastases (BM) are diagnosed in up to 40% of HER2-positive breast cancer patients. Standard treatment includes local approaches such as whole-brain radiotherapy (WBRT), radiosurgery, and neurosurgery. The landscape trial established primary systemic therapy as an effective and safe alternative to WBRT in selected patients with Her2-positive BM. We aim to further focus on the role of systemic therapy in oligosymptomatic patients by presenting this case report. We report on a 50-year-old patient diagnosed with multiple BM 5 years after early breast cancer diagnosis. As the patient was asymptomatic and had a favorable diagnosis-specific GPA score, she received primary systemic treatment with T-DM1. She achieved partial remission within the brain for eight treatment cycles and then progressed despite stable extracranial disease. As the patient remained asymptomatic and refused WBRT, we decided upon trastuzumab, lapatinib plus capecitabine as second-line therapy. Another partial remission of BM was observed; to date, she has received 11 treatment cycles without any sign of disease progression. In this case, WBRT was delayed by at least 14 months, again indicating the activity of systemic treatment in BM. Apparently, in selected patients, BM can be controlled with multiple lines of systemic therapy similar to extracranial disease. Further investigation of systemic treatment approaches is therefore warranted.

    The capecitabine and temozolomide (CAPTEM) regimen is active in the treatment of metastatic pancreatic neuroendocrine tumors (pNETs), with response rates ranging from 30 to 70%. Small retrospective studies suggest that O(6)-methylguanine DNA methyltransferase (MGMT) deficiency predicts response to temozolomide. High tumor proliferative activity is also commonly perceived as a significant predictor of response to cytotoxic chemotherapy. It is unclear whether chromosomal instability (CIN), which correlates with alternative lengthening of telomeres (ALT), is a predictive factor. In this study, we evaluated 143 patients with advanced pNET who underwent treatment with CAPTEM for radiographic and biochemical response. MGMT expression (n=52), grade (n=128) and ALT activation (n=46) were investigated as potential predictive biomarkers. Treatment with CAPTEM was associated with an overall response rate (ORR) of 54% by RECIST 1.1. Response to CAPTEM was not influenced by MGMT expression, proliferative activity or ALT pathway activation. Based on these results, no biomarker-driven selection criteria for use of the CAPTEM regimen can be recommended at this time. PMID:27552969

    Monitoring the interaction between drugs and proteins is critical to understanding drug transport and metabolism underlying pharmacodynamics. The binding capacities to human serum albumin of two anticancer drugs, capecitabine and gefitinib, were compared via an approach combining (19)F NMR, (1)H saturation transfer difference (STD) NMR, circular dichroism and docking simulations. Results showed that the two drugs interaction with human serum albumin caused (19)F NMR signal shifted to different directions. Capecitabine had accurate binding site and higher binding affinity than gefitinib. This study provided fresh insights into ligand-protein interaction and the strength of (19)F NMR approach in biomedical research was well illustrated in this case. PMID:27392172

    Full Text Available Pain from bone metastases of breast cancer origin is treated with localized radiation. Modulating doses and schedules has shown little efficacy in improving results. Given the synergistic therapeutic effect reported for combined systemic chemotherapy with local radiation in anal, rectal, and head and neck malignancies, we sought to evaluate the tolerability and efficacy of combined capecitabine and radiation for palliation of pain due to bone metastases from breast cancer.Twenty-nine women with painful bone metastases from breast cancer were treated with external beam radiation in 10 fractions of 3 Gy, 5 fractions a week for 2 consecutive weeks. Oral capecitabine 700 mg/m(2 twice daily was administered throughout radiation therapy. Rates of complete response, defined as a score of 0 on a 10-point pain scale and no increase in analgesic consumption, were 14% at 1 week, 38% at 2 weeks, 52% at 4 weeks, 52% at 8 weeks, and 48% at 12 weeks. Corresponding rates of partial response, defined as a reduction of at least 2 points in pain score without an increase in analgesics consumption, were 31%, 38%, 28%, 34% and 38%. The overall response rate (complete and partial at 12 weeks was 86%. Side effects were of mild intensity (grade I or II and included nausea (38% of patients, weakness (24%, diarrhea (24%, mucositis (10%, and hand and foot syndrome (7%.External beam radiation with concurrent capecitabine is safe and tolerable for the treatment of pain from bone metastases of breast cancer origin. The overall and complete response rates in our study are unusually high compared to those reported for radiation alone. Further evaluation of this approach, in a randomized study, is warranted.ClinicalTrials.gov NCT01784393NCT01784393.

    In this phase II study we investigated the safety and efficacy of combination capecitabine and {sup 177}Lu-octreotate for the treatment of disseminated, progressive, unresectable neuroendocrine tumours (NETs). Enrolled in the study were 33 patients with biopsy-proven NETs, positive {sup 111}In-octreotide scintigraphy and progressive disease measurable by CT/MRI who were to receive four cycles of 7.8 GBq {sup 177}Lu-octreotate 8-weekly, with 14 days of 1,650 mg/m{sup 2} capecitabine per day. Of the 33 patients, 25 completed four cycles. Minimal transient myelosuppression at 3-4 weeks caused grade 3 thrombocytopenia in one patient but no neutropenia. Nephrotoxicity was absent. Critical organ radiation dosimetry provided median estimates of the dose per cycle to the kidneys of 2.4 Gy and to the liver of 4.8 Gy, and showed cumulative doses all below toxic thresholds. Objective response rates (ORR) were 24% partial response (PR), 70% stable disease (SD) and 6% progressive disease. Median progression-free survival and median overall survival had not been reached at a median follow-up of 16 months (range 5-33 months). Survival at 1 and 2 years was 91% (95% CI 75-98%) and 88% (95% CI 71-96%), respectively. The addition of capecitabine radiosensitizing chemotherapy does not increase the minimal toxicity of {sup 177}Lu-octreotate radiopeptide therapy and led to an ORR of 24% PR and 70% minor response or SD in patients with progressive metastatic NETs. Tumour control and stabilization of disease was obtained in 94% of these patients. (orig.)

    AIM: To evaluate the efficacy and toxicity of postoperative chemoradiation using FP chemotherapy and oral capecitabine during radiation for advanced gastric cancer following curative resection.METHODS: Thirty-one patients who had underwent a potentially curative resection for Stage Ⅲ and Ⅳ (MO) gastric cancer were enrolled. Therapy consists of one cycle of FP (continuous infusion of 5-FU 1000 mg/m2 on d 1 to 5 and cisplatin 60 mg/m2 on d 1) followed by 4500 cGy (180 cGy/d) with capecitabine (1650 mg/m2 daily throughout radiotherapy). Four wk after completion of the radiotherapy, patients received three additional cycles of FP every three wk. The median follow-up duration was 22.2 mo.RESULTS: The 3-year disease free and overall survival in this study were 82.7% and 83.4%, respectively. Four patients (12.9%) showed relapse during follow-up. Eight patients did not complete all planned adjuvant therapy.Grade 3/4 toxicities included neutropenia in 50.2%, anemia in 12.9%, thrombocytopenia in 3.2% and nausea/vomiting in 3.2%. Neither grade 3/4 hand foot syndrome nor treatment related febrile neutropenia or death were observed.CONCLUSION: These preliminary results suggest that this postoperative adjuvant chemoradiation regimen of FP before and after capecitabine and concurrent radiotherapy appears well tolerated and offers a comparable toxicity profile to the chemoradiation regimen utilized in INT-0116. This treatment modality allowed successful loco-regional control rate and 3-year overall survival.

    Full Text Available We report a case of coexisting urothelial cancer and renal tuberculosis in the same kidney. The patient is a 72-year-old female with a remote history of treated pulmonary tuberculosis who presented with haematuria, initial investigation of which elucidated no definitive cause. Almost 1 year later, a diagnosis of metastatic urinary tract cancer was made. The patient received chemotherapy for advanced collecting duct type renal cell carcinoma, based on histological features of renal biopsy. Subsequent confirmatory immunostains however led to a revised diagnosis of urothelial cancer, necessitating a change in chemotherapy regimen. A diagnosis of ipsilateral renal tuberculosis was made based on TB-PCR testing of renal biopsy tissue and anti-TB therapy was coadministered with chemotherapy. The patient died 9 months after diagnosis of metastatic urothelial cancer.

  9. Concurrent chemoradiation of metastases with capecitabine and oxaliplatin and 3D-CRT in patients with oligometastatic colorectal cancer: results of a phase I study

    International Nuclear Information System (INIS)

    Local control appears to be an important treatment aim in patients with limited metastases (oligometastases) of colorectal cancer (CRC). Those patients show a favourable prognosis, if - in addition to the local effective treatment - an occurrence of new metastases may also be postponed by effective systemic therapy. The purpose of this dose escalation phase I study was to establish the efficacy of local radiotherapy (RT) of oligometastatic CRC with a concurrent standard chemotherapy regimen. Patients with first-, second- or third-line therapy of oligometastatic CRC (1–3 metastases or local recurrence plus max. 2 metastases) received capecitabine (825 mg/m2/d BID d 1–14; 22–35) and oxaliplatin (50 mg/m2 d 1, 8, 22, 29). 3D-conformal RT of all metastatic lesions was delivered in 2.0 Gy up to 36 Gy to 50 Gy (3 dose levels). Primary endpoint was the maximal tolerable dose (MTD) of RT defined as the level at which two or more of six patients experienced dose-limiting toxicity (DLT). Between 09/2004 and 08/2007, 9 patients (7 male, 2 female, 50–74 years) were enrolled, 6 patients treated at dose level 1 (36 Gy), 3 patients at dose level 2 (44 Gy). 1 patient from the first cohort experienced DLT (oxaliplatin-related hypersensitivity reaction). No radiation-induced DLT occurred. 6/9 patients achieved objective response (partial remission). One year after initiation, all patients were alive, 6 patients survived (16 to 54 months) patients died of tumor progression (14 to 23 months). The phase II part of the trial had to be closed due to recruitment failure. Local 3D-CRT to metastatic lesions in addition to standard chemotherapy was feasible, DLT was not documented. 3/9 patients survived for a period of 3.5 to 4.4 years (time at the last evaluation). Radiotherapy of metastatic lesions should be incorporated into subsequent trials

    Background. The approved capecitabine regimen as monotherapy in metastatic breast cancer (MBC) is 1,250 mg/m2 twice daily for 2 weeks on and 1 week off (Cint). Dose modifications are often required because of severe hand-foot syndrome (HFS). We tested a continuous regimen with a lower daily dose but a similar cumulative dose in an attempt to reduce the severity of adverse events (AEs) while maintaining efficacy. Methods. We randomized 195 patients with HER-2/neu-negative MBC to capecitabine 800 mg/m2 twice daily throughout the 21-day cycle (Ccont) or to Cint to assess noninferiority in the percentage of patients free of progression at 1 year. Secondary endpoints included efficacy and safety. Associations between polymorphisms in capecitabine metabolism-related genes and drug response were assessed. Results. The percentage of patients free of progression at 1 year was 27.3% with Cint versus 25.3% with Ccont (difference of −2.0%; 95% confidence interval: −15.5% to 11.5%, exceeding the 15% deemed noninferior). Differences regarding other efficacy variables were also not found. Grade 3–4 HFS was the most frequent AE (41.1% in Cint vs. 42.3% in Ccont). Grade 3–4 neutropenia, thrombocytopenia, diarrhea, and stomatitis were more frequent with Cint. A 5′ untranslated region polymorphism in the carboxylesterase 2 gene was associated with HFS. One polymorphism in cytidine deaminase and two in thymidine phosphorylase were associated with survival. Conclusion. Our study was unable to show noninferiority with the continuous capecitabine regimen (Ccont) compared with the approved intermittent regimen (Cint). Further investigation is required to improve HFS. Polymorphisms in several genes might contribute to interindividual differences in response to capecitabine. PMID:25601966

    Full Text Available Abstract Background The integration of the non-cross-resistant chemotherapeutic agents capecitabine and vinorelbine into an intensified dose-dense sequential anthracycline- and taxane-containing regimen in high-risk early breast cancer (EBC could improve efficacy, but this combination was not examined in this context so far. Methods Patients with stage II/IIIA EBC (four or more positive lymph nodes received post-operative intensified dose-dense sequential epirubicin (150 mg/m² every 2 weeks and paclitaxel (225 mg/m² every 2 weeks with filgrastim and darbepoetin alfa, followed by capecitabine alone (dose levels 1 and 3 or with vinorelbine (dose levels 2 and 4. Capecitabine was given on days 1-14 every 21 days at 1000 or 1250 mg/m2 twice daily (dose levels 1/2 and 3/4, respectively. Vinorelbine 25 mg/m2 was given on days 1 and 8 of each 21-day course (dose levels 2 and 4. Results Fifty-one patients were treated. There was one dose-limiting toxicity (DLT at dose level 1. At dose level 2 (capecitabine and vinorelbine, five of 10 patients experienced DLTs. Therefore evaluation of vinorelbine was abandoned and dose level 3 (capecitabine monotherapy was expanded. Hand-foot syndrome and diarrhoea were dose limiting with capecitabine 1250 mg/m2 twice daily. At 35.2 months' median follow-up, the estimated 3-year relapse-free and overall survival rates were 82% and 91%, respectively. Conclusions Administration of capecitabine monotherapy after sequential dose-dense epirubicin and paclitaxel is feasible in node-positive EBC, while the combination of capecitabine and vinorelbine as used here caused more DLTs.

    Overexpression of human epidermal growth factor receptor-2 (HER2) in metastatic breast cancer (MBC) is associated with poor prognosis. This single-arm open-label trial (EGF109491; NCT00508274) was designed to confirm the efficacy and safety of lapatinib in combination with capecitabine in 52 heavily pretreated Chinese patients with HER2-positive MBC. The primary endpoint was clinical benefit rate (CBR). Secondary endpoints included progression-free survival (PFS), time to response (TTR), duration of response (DoR), central nervous system (CNS) as first site of relapse, and safety. The results showed that there were 23 patients with partial responses and 7 patients with stable disease, resulting in a CBR of 57.7%. The median PFS was 6.34 months (95% confidence interval, 4.93-9.82 months). The median TTR and DoR were 4.07 months (range, 0.03-14.78 months) and 6.93 months (range, 1.45-9.72 months), respectively. Thirteen (25.0%) patients had new lesions as disease progression. Among them, 2 (3.8%) patients had CNS disease reported as the first relapse. The most common toxicities were palmar-plantar erythrodysesthesia (59.6%), diarrhea (48.1%), rash (48.1%), hyperbilirubinemia (34.6%), and fatigue (30.8%). Exploratory analyses of oncogenic mutations of PIK3CA suggested that of 38 patients providing a tumor sample, baseline PIK3CA mutation status was not associated with CBR (P = 0.639) or PFS (P = 0.989). These data confirm that the lapatinib plus capecitabine combination is an effective and well-tolerated treatment option for Chinese women with heavily pretreated MBC, irrespective of PIK3CA status.

    Epirubicin, cisplatin and continuous infusion of 5-FU is a widely used palliative regimen in patients with gastric cancer. If cisplatin is substituted by oxaliplatin and 5-FU by capecitabine this regimen can be administered in the outpatient setting. Dose-limiting toxicity of oxaliplatin...... is peripheral sensory neuropathy and it is recommended to give oxaliplatin as a 120 min infusion. However, in patients with colorectal cancer a 30 min infusion of oxaliplatin can safely be administered without increasing neurotoxicity, standard infusion time is 30 min at our departments. In our phase I study...... the recommended doses of EXE was established (Dupont et al, 2006). Patients with non-resectable gastric adenocarcinoma were eligible. Patients received EXE (epirubicin 50 mg m(-2) day 1; capecitabine 1000 mg m(-2) day(-1) continuously and oxaliplatin 130 mg m(-2) day 1) as outpatient therapy every third week...

    Full Text Available Spontaneous intracranial hypotension (SICH is an entity, which is secondary to iatrogenic manipulation and breaching of dura. Postural headache in patients should be suspected, cranial magnetic resonance imaging (MRI is essential for precise diagnosis. Hallmark of MRI is regular shape of pachymeningeal gadolinium enhancement and subdural effusion. It may mimic central nervous system (CNS metastasis. Prevention of such cases from receiving cranial radiotherapy by misinterpretation of the gadolinium enhancement as CNS metastasis is an important issue. Capecitabine is an antineoplastic agent, of which metabolites can cross blood-brain barrier in CNS via epithelial tissue. It may cause decrease in CSF production. SICH might be the clinical reflection of this decrease in CSF production. Review of the English literature revealed limited data because of the very little experience with oncologic patients suffering from intracranial hypotension. We report a case of spontaneous intracranial hypotension during capecitabine treatment. Patient was completely well following drug discontinuation and supportive treatment.

    The use of anticancer drugs in palliative settings is often limited by their severe toxic effects. In gastrointestinal carcinomas the 5-fluorouracil-based palliative regimen FOLFOX-4 is often preferred to the equally effective, but more convenient oral capecitabine-based regimen XELOX. This preference is mainly based on the fact that the highly effective oral agent capecitabine induces hand-foot syndrome (HFS). In this study, we investigated whether the continuous administration of skin prophylaxis (10% urea, panthenol, bisabolol, vitamin A, C and E) is capable of protecting against capecitabine-induced HFS and allowing a more convenient oral therapeutic option. In this retrospective analysis, the toxicity profiles, according to NCI CTCAE 3.0 criteria, of 54 patients with gastrointestinal cancer who received either XELOX (34 patients) or FOLFOX-4 (20 patients) were compared using Fisher tests. The treatment protocols that were compared, herein, did not differ significantly in the majority of the analyzed items, with the exception of increased nausea (XELOX-70), fatigue (XELOX-130) and tumor pain (XELOX-70 and XELOX-130). No significant differences were observed among the various groups with regard to emesis, diarrhea, mucositis, exanthema, alopecia, loss of weight and the incidence of infections. In particular, no significant differences in toxicity levels occurred in terms of dose, and HFS was limited if skin prophylaxis was performed continuously. XELOX-based palliative regimens provide an equally effective and comparably toxic therapeutic alternative to FOLFOX-4 if HFS prophylaxis is performed continuously. Since the oral administration of capecitabine is a more convenient method of application, it provides patients with a quality of life-preserving therapeutic alternative. PMID:22783416

    Full Text Available BACKGROUND: Lapatinib plus capecitabine is an effective treatment option for trastuzumab-refractory HER2-positive metastatic breast cancer. We have investigated the correlation between quantitative measures of HER2, p95HER2, and HER3 and treatment outcomes using lapatinib and capecitabine. METHODS: Total HER2 (H2T, p95HER2 (p95, and total HER3 (H3T expression were quantified in formalin-fixed paraffin-embedded samples using the VeraTag assays. Patients received lapatinib and capecitabine treatment following trastuzumab failure according to the Lapatinib Expanded Access Program. The association between the protein expression levels and clinical outcomes was analyzed. RESULTS: A total of 52 patients were evaluable. H2T level was significantly higher in responders (median 93.49 in partial response, 47.66 in stable disease, and 17.27 in progressive disease; p = 0.020. Longer time-to-progression (TTP was observed in patients with high H2T [p = 0.018, median 5.2 months in high (>14.95 vs. 1.8 in low (0.605 vs. 2.2 in low (<0.605]. Patients having both high H2T and high H3T had significantly longer TTP [adjusted hazard ratio (HR 0.38 (95% CI 0.20-0.73, p = 0.004] and overall survival [adjusted HR 0.46 (95% CI 0.24-0.89, p = 0.020]. No significant association between p95 and response or survival was observed. CONCLUSIONS: These data suggest a correlation between high HER2 and high HER3 expression and treatment outcome, while no significant difference was observed between clinical outcome and p95 expression level in this cohort of HER2-positive, trastuzumab-refractory metastatic breast cancer patients treated with lapatinib and capecitabine.

    An exploratory phase II biomarker-embedded trial (LPT109747; NCT00526669) designed to determine the association of lapatinib-induced fluoropyrimidine gene changes with efficacy of lapatinib plus capecitabine as first-line treatment for advanced gastric cancer or gastroesophageal junction adenocarcinoma independent of tumor HER2 status. Tumor biopsies obtained before and after 7-day lapatinib (1,250 mg) to analyze changes in gene expression, followed by a 14-day course of capecitabine (1,000 mg/m(2) twice daily, 14/21 days) plus lapatinib 1,250 mg daily. Blood samples were acquired for pharmacokinetic analysis. Primary clinical objectives were response rate (RR) and 5-month progression-free survival (PFS). Secondary objectives were overall survival (OS), PFS, time to response, duration of response, toxicity, and identification of associations between lapatinib pharmacokinetics and biomarker endpoints. Primary biomarker objectives were modulation of 5-FU-pathway genes by lapatinib, effects of germline SNPs on treatment outcome, and trough steady-state plasma lapatinib concentrations. Sixty-eight patients were enrolled; (75% gastric cancer, 25% gastroesophageal junction). Twelve patients (17.9%) had confirmed partial response, 31 (46.3%) had stable disease, and 16 (23.9%) had progressive disease. Median PFS and OS were 3.3 and 6.3 months, respectively. Frequent adverse events included diarrhea (45%), decreased appetite (39%), nausea (36%), and fatigue (36%). Lapatinib induced no changes in gene expression from baseline and no significant associations were found for SNPs analyzed. Elevated baseline HER3 mRNA expression was associated with a higher RR (33% vs. 0%; P = 0.008). Lapatinib plus capecitabine was well tolerated, demonstrating modest antitumor activity in patients with advanced gastric cancer. The association of elevated HER3 and RR warrants further investigation as an important player for HER-targeted regimens in combination with capecitabine. Mol Cancer Ther

    Treatment with the radiolabelled somatostatin analogue {sup 177}Lu-octreotate results in tumour remission in 47% of patients with gastroenteropancreatic neuroendocrine tumours. Adding capecitabine to {sup 177}Lu-octreotate, as a radio-sensitiser, may enhance these anti-tumour effects. We now present the short-term toxicity profile of this novel combination. Seven patients were treated with 7.4 GBq {sup 177}Lu-octreotate and capecitabine (1650 mg/m{sup 2} per day) for 2 weeks with an intended number of four cycles. Toxicity, and especially haematological and renal parameters, were monitored on a weekly basis for the first two cycles and 4 and 6 weeks after subsequent cycles. None of the patients had hand-foot syndrome. One patient had grade 1 stomatitis occurring after one of four cycles. Grade 3 or 4 leukopenia or neutropenia did not occur. One patient had grade 3 anaemia, but none had grade 4 anaemia. One patient had grade 2 thrombocytopenia after the fourth cycle, and one had grade 3 thrombocytopenia. Grade 4 thrombocytopenia did not occur. No significant changes in serum creatinine levels were observed. None of the patients had symptoms of cardiac ischaemia. Treatment with the combination of {sup 177}Lu-octreotate and capecitabine was feasible and safe considering acute and subacute side effects. We therefore started a randomised, controlled clinical trial to compare this combination with {sup 177}Lu-octreotate as single agent with regard to anti-tumour effects and side effects. (orig.)

    We performed a prospective phase II trial to investigate the safety and efficacy of radiotherapy combined with capecitabine in patients suffering from a recurrence of a squamous cell carcinoma of the head and neck (SCCHN) within a previously irradiated field. A total of 31 evaluable patients with recurrent SCCHN received re-irradiation with a total dose of 50 Gy (25 fractions over 5 weeks) up to a maximum of 60 Gy combined with 900 mg/m{sup 2}/day capecitabine given on the days of radiotherapy. The median time to relapse after the first course of radiotherapy was 15 months. The overall response rate in our study was 68% including 6 patients with a complete response. The median overall survival was 8.4 months. Grade 3 or 4 mucositis occurred in 4 patients and 1 patient, respectively. No grade 4 hematological toxicities were observed; 1 patient had grade 3 anemia. The cumulative median lifetime dose was 116 Gy. Capecitabine combined with re-irradiation is a well-tolerated treatment in patients with recurrent SCCHN. In light of its good tolerability, it appears to be a potential option for patients with a reduced performance status and may also serve as a basis for novel treatment concepts, such as in combination with targeted therapies.

    The prognosis of patients with metastatic breast cancer remains poor, and thus novel therapeutic approaches are needed. Capecitabine, which is commonly used for metastatic breast cancer in different settings, is an inactive prodrug that takes advantage of elevated levels of thymidine phosphorylase (TP), a key enzyme that is required for its conversion to 5-fluororacil, in tumors. We demonstrated that histone deacetylase inhibitors (HDACi), including low anticonvulsant dosage of VPA, induced the dose- and time-dependent up-regulation of TP transcript and protein expression in breast cancer cells, but not in the non-tumorigenic breast MCF-10A cell line. Through the use of siRNA or isoform-specific HDACi, we demonstrated that HDAC3 is the main isoform whose inhibition is involved in the modulation of TP. The combined treatment with capecitabine and HDACi, including valproic acid (VPA), resulted in synergistic/additive antiproliferative and pro-apoptotic effects in breast cancer cells but not in TP-knockout cells, both in vitro and in vivo, highlighting the crucial role of TP in the synergism observed. Overall, this study suggests that the combination of HDACi (e.g., VPA) and capecitabine is an innovative antitumor strategy that warrants further clinical evaluation for the treatment of metastatic breast cancer.

    A 10-year-old girl with a family history of Hodgkin's lymphoma presented with a 2 month history of cervical lymphadenopathy and weight loss. Biopsy indicated concomitant nodal involvement by Langerhans cell histiocytosis and Hodgkin's lymphoma. Such an association is rare, especially so in children, but is not an isolated phenomenon, thereby prompting the question of whether Langerhans cell histiocytosis is a reactive or a neoplastic process.

    Full Text Available Abstract Background Local control appears to be an important treatment aim in patients with limited metastases (oligometastases of colorectal cancer (CRC. Those patients show a favourable prognosis, if - in addition to the local effective treatment - an occurrence of new metastases may also be postponed by effective systemic therapy. The purpose of this dose escalation phase I study was to establish the efficacy of local radiotherapy (RT of oligometastatic CRC with a concurrent standard chemotherapy regimen. Methods Patients with first-, second- or third-line therapy of oligometastatic CRC (1–3 metastases or local recurrence plus max. 2 metastases received capecitabine (825 mg/m2/d BID d 1–14; 22–35 and oxaliplatin (50 mg/m2 d 1, 8, 22, 29. 3D-conformal RT of all metastatic lesions was delivered in 2.0 Gy up to 36 Gy to 50 Gy (3 dose levels. Primary endpoint was the maximal tolerable dose (MTD of RT defined as the level at which two or more of six patients experienced dose-limiting toxicity (DLT. Results Between 09/2004 and 08/2007, 9 patients (7 male, 2 female, 50–74 years were enrolled, 6 patients treated at dose level 1 (36 Gy, 3 patients at dose level 2 (44 Gy. 1 patient from the first cohort experienced DLT (oxaliplatin-related hypersensitivity reaction. No radiation-induced DLT occurred. 6/9 patients achieved objective response (partial remission. One year after initiation, all patients were alive, 6 patients survived (16 to 54 months patients died of tumor progression (14 to 23 months. The phase II part of the trial had to be closed due to recruitment failure. Conclusions Local 3D-CRT to metastatic lesions in addition to standard chemotherapy was feasible, DLT was not documented. 3/9 patients survived for a period of 3.5 to 4.4 years (time at the last evaluation. Radiotherapy of metastatic lesions should be incorporated into subsequent trials.

    Abstract Introduction Celiac disease and cystic fibrosis have many common manifestations, such as malabsorption, steatorrhea and growth failure, and were for many years recognized as one clinical entity. Since their recognition as two separate diseases, their co-existence in a patient has been described sporadically; around 20 cases have been described in the literature. Taking into consideration the incidences of the two diseases, the chance of them occurring together is one in 2,000,000 in ...

  18. Results of a phase I study to determine the maximum tolerated dose of capecitabine when given concurrently with radical radiotherapy in the treatment of squamous cell carcinoma of the head and neck

    International Nuclear Information System (INIS)

    Capecitabine is preferentially converted to 5-fluorouracil within tumours, exploiting the higher levels of thymidine phosphorylase (TP) found in areas of poor perfusion and hypoxia. In addition radiation leads to up regulation of TP expression. To exploit these advantages of capecitabine as a synchronous chemoradiotherapy agent patients with advanced squamous cell carcinoma of the head and neck were recruited into a phase I non-randomised dose finding study. Capecitabine was given twice daily, 7 days a week at a dose starting at 350 mg/m2 bid. Radiotherapy using a beam directed technique was prescribed to 55 Gy in 20 fractions over 4 weeks. A total of 24 patients were treated. Dose-limiting toxicity (grade IV mucositis) was reached at a capecitabine dose of 550 mg/m2 bid. Radiotherapy was completed without delay in all cases. There was no systemic drug related toxicity. Capecitabine offers the prospect of an orally administered drug for use synchronously with radiotherapy, which in doses up to 500 mg/m2 bid is well tolerated

In this randomized, Phase III trial, 137 patients with operable primary breast cancer (T2-0, N0-1 who were tested axillary LN positive through aspiration biopsy of axillary LNs were randomized (1:1 to four 3-weekly cycles of XEC or FEC. Patients underwent surgery within 4–6 weeks after the fourth cycle, followed by four adjuvant cycles of 3-weekly XT or T. The primary end point was tumor pathological complete response. Toxicity profiles were secondary objectives. In total, 131 patients had clinical and radiological evaluation of response and underwent surgery. Treatment with XEC led to an increased rate of pathological complete response in primary tumor (18% vs 6%, respectively, P=0.027 and objective remission rate (87% vs 73%, P=0.048 compared to FEC. Clinical complete response occurred in 20% and 7% for XEC and FEC, respectively.

    2015-01-01

    Full Text Available Concomitant pituitary adenoma (PA and Rathke’s cleft cyst (RCC are rare. In some cases, such PA is known to produce pituitary hormones. A 53-year-old man was admitted to our hospital with a diagnosis of lacunar infarction in the left basal ganglia. Magnetic resonance imaging (MRI incidentally showed a suprasellar mass with radiographic features of RCC. When he consulted with a neurosurgical outpatient clinic, acromegaly was suspected based on his appearance. A diagnosis of growth hormone- (GH- producing PA was confirmed from hormonal examinations and additional MRI. Retrospectively, initial MR images also showed intrasellar mass that is compatible with the diagnosis of PA other than suprasellar RCC. The patient underwent endonasal-endoscopic removal of the PA. Since we judged that the RCC of the patient was asymptomatic, only the PA was completely removed. The postoperative course of the patient was uneventful and GH levels gradually normalized. Only 40 cases of PA with concomitant RCC have been reported to date, including 13 cases of GH-producing PA. In those 13 cases, RCC tended to be located in the sella turcica, and suprasellar RCC like this case appears rare. In a few cases, concomitant RCCs were fenestrated, but GH levels normalized postoperatively as in the cases without RCC fenestration. If radiographic imaging shows typical RCC, and PA is not obvious at first glance, the possibility of concomitant PA still needs to be considered. In terms of treatment, removal of the RCC is not needed to achieve hormone normalization.

  1. Postoperative Chemotherapy Followed by Conformal Concomitant Chemoradiotherapy in High-Risk Gastric Cancer

    International Nuclear Information System (INIS)

    Purpose: To analyze the efficacy, toxicity, and pattern of relapse after adjuvant cisplatin-based chemotherapy followed by three-dimensional irradiation and concomitant LV5FU2 chemotherapy (high-dose leucovorin and 5-fluorouracil bolus plus continuous infusion) in the treatment of completely resected high-risk gastric cancer. Methods and Materials: This was a retrospective analysis of 52 patients with high-risk gastric cancer initially treated by total/partial gastrectomy and lymphadenectomy between January 2002 and June 2007. Median age was 54 years (range, 36–75 years). Postoperative treatment consisted of 5-fluorouracil and cisplatin chemotherapy. Adjuvant chemotherapy was followed by three-dimensional conformal radiotherapy in the tumor bed and regional lymph nodes at 4500 cGy/25 fractions in association with concomitant chemotherapy. Concomitant chemotherapy consisted of a 2-h infusion of leucovorin (200 mg/m²) followed by a bolus of 5-fluorouracil (400 mg/m²) and then a 44-h continuous infusion of 5-fluorouracil (2400–3600 mg/m²) given every 14 days, for three cycles (LV5FU2 protocol). Results: Five-year overall and disease-free survival were 50% and 48%, respectively. Distant metastases and peritoneal spread were the most frequent sites of relapse (37% each). After multivariate analysis, only pathologic nodal status was significantly associated with disease-free and overall survival. Acute toxicities were essentially gastrointestinal and hematologic. One myocardial infarction and one pulmonary embolism were also reported. Eighteen patients had a radiotherapy program interruption because of acute toxicity. All patients but 2 have completed radiotherapy. Conclusion: Postoperative cisplatin-based chemotherapy followed by conformal radiotherapy in association with concurrent 5-fluorouracil seemed to be feasible and resulted in successful locoregional control.

  3. Concomitant pilocarpine during head and neck irradiation is associated with decreased posttreatment xerostomia

    International Nuclear Information System (INIS)

    Purpose: To retrospectively compare subjective postirradiation xerostomia scores of patients who received concomitant oral pilocarpine during radiotherapy for head and neck cancer and 3 months thereafter with those of similar cohorts who did not receive pilocarpine. Methods and Materials: Subjective xerostomia was assessed using a visual analog scale xerostomia questionnaire that measured oral dryness, oral comfort, difficulty with sleep, speech, and eating. The concomitant pilocarpine group had both parotid glands in the initial field treated to at least 45 Gy and received 5 mg pilocarpine hydrochloride four times per day (q.i.d.) beginning on the first day of radiotherapy and continuing for 3 months after completion of radiation. The control cohort had also received at least 45 Gy to both parotid glands and had not received pilocarpine at the time of evaluation. Scores on the visual analog scale were averaged and compared using the Student's t-test. Results: Seventeen patients who received concomitant pilocarpine during head and neck irradiation and 18 patients who had not been treated with pilocarpine were available for follow-up. The mean intervals between completion of radiation and evaluation of xerostomia were 17 months and 16 months, respectively. Only one of the pilocarpine-treated patients was still taking pilocarpine at the time of evaluation. For each of the individual components of xerostomia scored on the visual analog scale, as well as the composite of all components, the group that had received oral pilocarpine during radiation had significantly less xerostomia (p < 0.01 for each). Conclusions: The use of 5 mg oral pilocarpine q.i.d. during radiotherapy for head and neck cancer and 3 months thereafter was associated with significantly less subjective xerostomia than that reported by a similar cohort of patients who had not received pilocarpine. The continued use of pilocarpine does not appear to be necessary to maintain this benefit in most patients

    Purpose: This prospective, phase 2 study aimed at assessing the efficacy of accelerated fractionation radiation therapy by concomitant boosts (CBs) associated with chemoradiation therapy (CRT) of the whole pelvis, in improving the rate of pathological complete response (pCR) to treatment in patients with International Federation of Gynaecology and Obstetrics (FIGO) stage IB2-IVA locally advanced cervical cancer. Methods and Materials: Neoadjuvant CRT included conformal irradiation of the whole pelvis with a total dose of 39.6 Gy (1.8 cGy/fraction, 22 fractions), plus additional irradiation of primary tumor and parametria with 10.8 Gy administered with CBs (0.9 cGy/fraction, 12 fractions, every other day). Concomitant chemotherapy included cisplatin (20 mg/m{sup 2}, days 1-4 and 26-30 of treatment), and capecitabine (1300 mg/m{sup 2}/daily, orally) during the first 2 and the last 2 weeks of treatment. Radical hysterectomy plus pelvic with or without aortic lymphadenectomy was performed within 6 to 8 weeks from CRT. Toxicity was recorded according to Radiation Therapy Oncology Group toxicity criteria and Chassagne grading system. Based on the Simon design, 103 cases were required, and the regimen would be considered active if >45 pCR were registered (α error = 0.05; β error = 0.1). Results: pCR was documented in 51 cases (50.5%), and the regimen was considered active, according to the planned statistical assumptions. At median follow-up of 36 months (range: 7-85 months), the 3-year local failure rate was 7%, whereas the 3-year disease-free and overall survival rates were 73.0% and 86.1%, respectively. Grade 3 leukopenia and neutropenia were reported in only 1 and 2 cases, respectively. Gastrointestinal toxicity was always grade 1 or 2. Conclusions: Addition of CBs in the accelerated fractionation modality to the whole pelvis chemoradiation followed by radical surgery results in a high rate of pathologically assessed complete response to CRT and a very

    @@ Aortic dissection occurs when layers of the aortic walls are separated by the blood flow through an intimal tear. Dissection of the aorta most frequently originates in the ascending aorta (70%), followed by the descending aorta (22%), the aortic arch (7%) and the abdominal aorta (1/%).1 The dissection limited to the abdominal aorta is rare.2 An isolated abdominal aortic dissection (IAAD) concomitant with an abdominal aortic aneurysm (AAA) is uncommon. We present here one patient with IAAD and AAA treated by endovascular therapy.

  6. Concomitant Graves' disease and Hashimoto's thyroiditis, presenting as primary hypothyroidism.

    Hypothyroidism in patients with Graves\\' disease is usually the result of ablative treatment. We describe a 58 year old man with Graves\\' ophthalmopathy and pre-tibial myxoedema, who presented with spontaneous primary hypothyroidism. Circulating TSH receptor antibody activity was increased, while thyroid microsomal antibody was detectable in titres greater than one in one hundred thousand. It is likely that the TSH receptor antibody of Graves\\' disease was ineffective in stimulating hyperthyroidism because of concomitant thyroid destruction due to Hashimoto\\'s disease. Alternatively, primary hypothyroidism could have resulted from the effects of a circulating TSH receptor blocking antibody.

    Ptyalism gravidarum, or sialorrhea, is the excessive secretion of saliva during pregnancy. Treatment of ptyalism gravidarum is often challenging due to its unknown etiologies. This article discusses a case of ptyalism gravidarum with concomitant hyperemesis in which the condition was successfully treated with hypnosis. A 28-year-old woman presented with ptyalism 2 months into her pregnancy and hyperemesis 3 months into pregnancy with associated vomiting that occurred following every meal. Hypnosis was administered at week 16 of pregnancy to eliminate ptyalism and hyperemesis, to prepare for childbirth, and to increase overall psychological well-being. Ptyalism resolved by week 36, concurrent with the final hypnosis session.

    We report a case of a 75-year-old man with cystic micropapillary neoplasm of peribiliary glands detected preoperatively by radiologic examination. Enhanced computed tomography showed a low-density mass 2.2 cm in diameter in the right hepatic hilum and a cystic lesion around the common hepatic duct. Under a diagnosis of perihilar cholangiocarcinoma, right hepatectomy with caudate lobectomy and bile duct resection were performed. Pathological examination revealed perihilar cholangiocarcinoma mainly involving the right hepatic duct. The cystic lesion was multilocular and covered by columnar lining epithelia exhibiting increased proliferative activity and p53 nuclear expression; it also contained foci of micropapillary and glandular proliferation. Therefore, the lesion was diagnosed as a cystic micropapillary neoplasm of peribiliary glands and resembled flat branch-type intraductal papillary mucinous neoplasm of the pancreas. Histological examination showed the lesion was discontinuous with the perihilar cholangiocarcinoma. Immunohistochemistry showed the cystic neoplasm was strongly positive for MUC6 and that the cholangiocarcinoma was strongly positive for MUC5AC and S100P. These results suggest these two lesions have different origins. This case warrants further study on whether this type of neoplasm is associated with concomitant cholangiocarcinoma as observed in pancreatic intraductal papillary mucinous neoplasm with concomitant pancreatic duct adenocarcinoma.

    International Nuclear Information System (INIS)

    Purpose: A prospective phase II trial was conducted to determine the efficacy and rate of organ preservation of alternate week concomitant chemoradiotherapy in stage II and III head and neck cancer. Methods: Forty-nine patients (10 stage II and 39 stage III) with squamous cell carcinoma of the head and neck region have been entered into a prospective phase II trial. Pretreatment evaluation included history and physical examination, computed tomography of the neck, bone scan, chest x-ray, panendoscopy and biopsy confirmation of malignancy. Therapy is given in 2 week cycles consisting of 5 days of concomitant chemoradiotherapy followed by a nine day break during which no treatment is given. Each cycle of treatment consists of 1.0 gm hydroxyurea P.O. every 12 hours for 6 days (11 doses per cycle) and 800mg/m2/d continuous infusion 5-fluorouracil along with concomitant radiation therapy (RT) administered in 1.8-2.0 Gy daily fractions for five days. This alternate week (week on/week off) schedule is continued for a total of 7 cycles resulting in an overall treatment time of 13 weeks and a total RT dose of 70 Gy. Extent of initial surgery included biopsy only (59.2%), minimal laser debulking (12.2%), and resection with or without neck dissection (28.6%). Results: The majority of patients are male (71.4%), with a median age of 61.3 years. Primary sites included oral cavity (16.3%), oropharynx (12.2%), larynx (57.1%), hypopharynx (8.1%), and nasopharynx (4.1%). T stage included T3 (32 patients, 65.3%), T2 (16 patients, 32.7%), and T1 (1 patient). N stage included N1 (17 patients, 34.7%), and N0 (32 patients, 65.3%). With a median follow-up of 27 months, the overall response rate is 100% (91.7 complete response, and 8.3% partial response). The 5 year actuarial local control, disease free survival, and overall survival is 90.1%, 88.3%, and 65.0%, respectively. One patient has failed with distant disease alone. Four patients had isolated local failures and (3(4)) were

    Abstract Extraintestinal manifestations (EIMs) cause increased morbidity and decreased quality of life in Crohn disease (CD). Ankylosing spondylitis (AS) belongs to EIMs. Very little is known on the clinical features of CD concomitant with AS. This study is to investigate the clinical features of CD patients with AS. We retrospectively collected all CD patients with AS in our hospital, and established a comparison group (CD without AS) with age, sex, and duration of Crohn disease matched. Clinical information was retrieved for comparison. Eight CD + AS patients were identified from 195 CD patients. Sixteen CD patients were randomly selected into comparison group. All CD + AS patients were male, HLA-B27 (+), and rheumatoid factor (−) with an average age of 40.8 ± 4.52 years. Significant correlation between disease activity of CD and AS was revealed (r = 0.857, P = 0.011). Significant correlation between disease activity of CD and functional limitation associated with AS was identified (r = 0.881, P < 0.01). C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), and globulin were positively correlated to Crohn disease activity index (CDAI), Bath AS disease activity index, and Bath AS functional index(BASFI) scores (r = 0.73–0.93, P < 0.05). Albumin was negatively associated with CDAI and BASFI (r = −0.73 to −0.91, P < 0.05). The ratio of albumin to globulin (Alb/Glo) was significantly related to all 3 scores (r = −0.81 to −0.91, P < 0.05). Male predominance with a 4.12% concomitant incidence of AS is observed in CD patients. Disease activity of CD correlates with disease activity of AS and functional limitation caused by AS. CRP, ESR, and Alb/Glo may serve as biomarkers for disease activity and functional limitation in CD patients concomitant with AS, although future studies are expected. PMID:27428240

    We report the case of a 22-year-old African American female who presented to another facility for routine follow-up in the 34th week of pregnancy with lower extremity swelling and nephrotic-range proteinuria. Although she was normotensive, it was initially thought that she had preeclampsia. She was monitored carefully and delivery was induced at 37 weeks of gestation. She was transferred to our hospital, where she was diagnosed with systemic lupus erythematosus (SLE) based on clinical and laboratory criteria. Renal biopsy revealed a surprising finding of minimal change disease (MCD) concomitant with class II lupus nephritis (LN). She was managed with pulses and then tapering doses of steroid therapy with dramatic resolution of the nephrotic syndrome. This case demonstrates not only the rare de novo occurrence of SLE in pregnancy, but the unique finding of MCD coexisting with class II LN. We propose that altered T cell activity may be the link between these seemingly distinct entities.

    The paper describes the unique geometric properties of ideal magnetohydrodynamics (MHD), and demonstrates how such features are inherited by extended MHD, viz. models that incorporate two-fluid effects (the Hall term and electron inertia). The generalized helicities, and other geometric expressions for these models are presented in a topological context, emphasizing their universal facets. Some of the results presented include: the generalized Kelvin circulation theorems; the existence of two Lie-dragged 2-forms; and two concomitant helicities that can be studied via the Jones polynomial, which is widely utilized in Chern-Simons theory. The ensuing commonality is traced to the existence of an underlying Hamiltonian structure for all the extended MHD models, exemplified by the presence of a unique noncanonical Poisson bracket, and its associated energy.

    Full Text Available Context Pancreatic neuroendocrine tumors (pNETs are notoriously resistant to currently available chemotherapy agents.Preclinical data has suggested synergy between temozolomide and capecitabine. Objective To report a retrospective data on the efficacy and safety of capecitabine and temozolomide (CAPTEM regimen in patients with metastatic pancreaticneuroendocrine tumors (pNETs who have failed prior therapies. Methods We reviewed the medical records of 7 patientswith metastatic pNETs who had had progressive cancer prior to treatment despite therapy, including long-acting releaseoctreotide (60 mg/month, chemotherapy and hepatic chemoembolization. Capecitabine was administered at a flat dose of1,000 mg orally twice daily on days 1-14 and temozolomide 200 mg/m2 was given in two divided doses daily on days 10-14of a 28-day cycle. Tumor assessments were repeated every two cycles and serum tumor markers were measured every cycle. Response to treatment was assessed using Response Evaluation Criteria in Solid Tumors (RECIST parameters, and toxicity was graded using the National Cancer Institute Common Terminology Criteria for Adverse Events (CTCAE, version 3.0. Results Among 7 patients treated, three patients achieved a partial response, and two patients had stable disease. Totalresponse rate was 43%, and clinical benefit (responders and stable disease was 71%. Median duration of response was 8months (range: 4-12 months. Grade 3 and 4 toxicities included grade 3 thrombocytopenia in one patient and grade 3 fatigue in one patient. The most common toxicities were grade 1 and 2 neutropenia, grade 1 fatigue, grade 1 and 2 hand-foot syndrome. Conclusions Our retrospective study showed that modified CAPTEM regimen was well-tolerated and produced comparable response to historical data in neuroendocrine tumors, including pNETs. Our study is unique as it only included patients with pNETs. Further prospective studies are warranted to evaluate the combination of

    Full Text Available Metastatic breast cancer (MBC remains an incurable disease despite major therapeutic advances. Pseudomonas aeruginosa-mannose-sensitive hemagglutinin (PA-MSHA has been established to have anti-proliferative effects against breast cancer cells in preclinical experiments, and is indicated for treatment of cancer in China. We performed a phase II trial combining PA-MSHA with capecitabine in patients with heavily pretreated MBC.Eligibility criteria included human epidermal growth factor receptor 2-negative MBC, prior therapy with anthracyclines and taxanes, at least one prior chemotherapy regimen for metastatic disease or early relapse after a taxane plus anthracycline adjuvant regimen, and adequate organ function and performance status. PA-MSHA 1 mg was administered subcutaneously every other day and capecitabine 1000 mg/m2 orally twice a day for 2 weeks on, 1 week off. The primary end point was progression-free survival.A total of 97 patients were enrolled. Median progression-free survival (PFS was 4.0 months [95 % confidence interval (CI 3.0-4.9], which was not significantly different from that in historical controls. However, median PFS was significantly longer (8.2 months; 95 % CI 6.7-9.7 in 24 patients with moderate immune-related adverse events (irAEs such as fever or skin induration at the injection site than in those with no or mild irAEs (3.1 months, 95 % CI 2.5-3.6; p = 0.003. Overall survival was also improved in these patients (25.4 vs. 16.4 months; p = 0.044. PA-MSHA has a good safety profile, with only 6 patients (6.2 % discontinuing treatment. PA-MSHA did not increase capecitabine-related toxicities such as hand-foot syndrome, nausea, and vomiting.Adding PA-MSHA to capecitabine has a good safety profile in patients with heavily pre-treated MBC, although benefit from this regimen might occur only in patients with moderate PA-MSHA-related adverse events.ClinicalTrials.gov NCT01380808.

    The aim of this study was to compare the effectiveness and toxicity of neoadjuvant chemotherapy regimens, xeloda/epirubicin/cyclophosphamide (XEC) vs 5-fluorouracil/epirubicin/cyclophosphamide (FEC), followed by adjuvant chemotherapy regimens, capecitabine/taxotere (XT) vs taxotere (T), in axillary lymph node (LN)-positive early-stage breast cancer. In this randomized, Phase III trial, 137 patients with operable primary breast cancer (T2-0, N0-1) who were tested axillary LN positive through aspiration biopsy of axillary LNs were randomized (1:1) to four 3-weekly cycles of XEC or FEC. Patients underwent surgery within 4–6 weeks after the fourth cycle, followed by four adjuvant cycles of 3-weekly XT or T. The primary end point was tumor pathological complete response. Toxicity profiles were secondary objectives. In total, 131 patients had clinical and radiological evaluation of response and underwent surgery. Treatment with XEC led to an increased rate of pathological complete response in primary tumor (18% vs 6%, respectively, P=0.027) and objective remission rate (87% vs 73%, P=0.048) compared to FEC. Clinical complete response occurred in 20% and 7% for XEC and FEC, respectively. Compared to FEC, XEC was associated with more hand-foot syndrome (57% vs 11%, P<0.001) and 3/4 grade nausea/vomiting/diarrhea (30% vs 14%, P=0.034) but less phlebitis (3% vs 14%, P=0.035). XT and T adjuvant chemotherapy regimens were well tolerated: treatment-related 3/4 grade adverse events occurred in 28% and 17% of patients receiving XT and T, respectively. PMID:27354816

    Full Text Available Ileocecal resection (ICR is a commonly required surgical intervention in unmanageable Crohn's disease and necrotizing enterocolitis. However, the impact of ICR, and the concomitant doses of antibiotic routinely given with ICR, on the intestinal commensal microbiota has not been determined. In this study, wild-type C57BL6 mice were subjected to ICR and concomitant single intraperitoneal antibiotic injection. Intestinal lumen contents were collected from jejunum and colon at 7, 14, and 28 days after resection and compared to non-ICR controls. Samples were analyzed by 16S rRNA gene pyrosequencing and quantitative PCR. The intestinal microbiota was altered by 7 days after ICR and accompanying antibiotic treatment, with decreased diversity in the colon. Phylogenetic diversity (PD decreased from 11.8 ± 1.8 in non-ICR controls to 5.9 ± 0.5 in 7-day post-ICR samples. There were also minor effects in the jejunum where PD values decreased from 8.3 ± 0.4 to 7.5 ± 1.4. PCoA analysis indicated that bacterial populations 28 days post-ICR differed significantly from non-ICR controls. Moreover, colon and jejunum bacterial populations were remarkably similar 28 days after resection, whereas the initial communities differed markedly. Firmicutes and Bacteroidetes were the predominant phyla in jejunum and colon before ICR; however, Firmicutes became the vastly predominant phylum in jejunum and colon 28 days after ICR. Although the microbiota returned towards a homeostatic state, with re-establishment of Firmicutes as the predominant phylum, we did not detect Bacteroidetes in the colon 28 days after ICR. In the jejunum Bacteroidetes was detected at a 0.01% abundance after this time period.

    Postoperative external beam radiotherapy was considered the standard adjuvant treatment for patients with glioblastoma multiforme until the advent of using the drug temozolomide (TMZ) in addition to radiotherapy. High-dose volume should be focal, minimizing whole brain irradiation. Modern imaging, using several magnetic resonance sequences, has improved the planning target volume definition. The total dose delivered should be in the range of 60 Gy in fraction sizes of 1.8-2.0 Gy. Currently, TMZ concomitant and adjuvant to radiotherapy has become the standard of care for glioblastoma multiforme patients. Radiotherapy dose-intensification and radiosensitizer approaches have not improved the outcome. In spite of the lack of high quality evidence, stereotactic radiotherapy can be considered for a selected group of patients. For elderly patients, data suggest that the same survival benefit can be achieved with similar morbidity using a shorter course of radiotherapy (hypofractionation). Elderly patients with tumors that exhibit methylation of the O-6-methylguanine-DNA methyltransferase promoter can benefit from TMZ alone.

    Concomitant physeal fractures of the distal femur and proximal tibia are very rare in children and adolescents. They are included in the classification of the ''floating knee'' injuries. Two cases with this combined injury are reported. They were closed injuries and in both patients the fracture of the proximal tibial epiphyseal plate was nondisplaced. In the first, a six-year-old girl, an early diagnosis was made radiographically. The intra-articular femoral fracture was operatively reduced and fixed. No growth abnormality was encountered 12 years later. The second patient, a 16-year-old boy, was conservatively treated for a displaced fracture-separation of the distal femoral epiphysis. Four weeks later there was physeal widening on both sides of the knee which indicated an associated fracture of the proximal tibial epiphyseal plate. One year after injury there was a varus deformity of the knee that was treated with a corrective osteotomy. Ten years later there is normal alignment of the leg. (orig.)

    Full Text Available Concomitant use of lithium and E.C.T has always been accused to cause delirium in patients receiving such a combination. In this study incidence of delirium in patients who receive lithium+E.C.T. concurrently has been compared with those who have been treated with E.C.T. only. Of 49 patients who had Bipolar Mood Disorder (B.M.D. 1 disorder (manic episode 24 were given E.C.T.+lithium and 25 were treated with E.C.T. Only, 3 patients of the first group and 2 patients of the second group developed delirium. The difference between two groups was not statistically significant. Another finding was that all cases of delirium developed in patients who were above 35 years old (P value=0.001. These findings show that combination of E.C.T. and Lithium may not be so harmful as it was once considered. On the other hand it could be concluded that increased age may be a risk factor for delirium in such a combination.

    Only rarely do corticotroph pituitary tumors become invasive leading to symptoms caused by compression of cranial nerves and other local structures. When aggressive pituitary neuroendocrine tumors do develop, conventional treatment options are of limited success. A 50-year-old man developed a giant invasive corticotroph pituitary tumor 2 years after initial presentation.

  7. Radiation myelitis after hypofractionated radiotherapy with concomitant gefitinib

    International Nuclear Information System (INIS)

    We describe the case of a 71-year-old Caucasian female with primary disseminated non-small cell cancer of the lung, presented for palliative radiotherapy of metastatic spread to the 9th and 11th thoracic vertebrae without intramedullary growth. Palliative radiotherapy with daily fractions of 3 Gy and a cumulative dose of 36 Gy to thoracic vertebrae 8-12 was performed. The patient received concomitantly 250 mg gefitinib daily. After a latent period of 16 months, the patient developed symptoms of myelitis. Magnetic resonance imaging (MRI) did not reveal any bony or intraspinal tumor progression, but spinal cord signal alteration. No response to steroids was achieved. The neurological symptoms were progressive in August 2013 with the right leg being completely plegic. The left leg was incompletely paralyzed. Deep and superficial sensitivity was also diminished bilaterally. The patient was completely urinary and anally incontinent. Contrary to the clinical findings, a follow-up MRI (July 2013) showed amelioration of the former signal alterations in the spinal cord. The diagnosis of paraneoplastic myelopathy was refuted by a negative test for autologous antibodies. At the last clinical visit in May 2014, the neurological symptoms were stable. The last tumor-specific treatment the patient is receiving is erlotinib 125 mg/d. We reviewed the literature and found no reported cases of radiation myelopathy after the treatment in such a setting. The calculated probability of such complication after radiotherapy alone is statistically measurable at the level of 0.02%. We suppose that gefitinib could also play a role in the development of this rare complication

    Dabigatran and rivaroxaban are novel, vitamin K-independent oral anticoagulants (NOACs) and act via antagonism of the coagulation factor (F) IIa (dabigatran) or FXa (rivaroxaban), respectively. Compared to vitamin-K-antagonists, NOACs have shown non-inferiority of risk and benefit in patients with non valvular atrial fibrillation (AF). In clinical practice there is increasing use of NOACs combined with platelet inhibitors in patients with AF and coronary artery disease. However, whether NOACs affect the function of platelet inhibitors remains incompletely known. This observational study aimed to assess the platelet function in patients receiving dabigatran or rivaroxaban and concomitant platelet inhibitors. A single centre observational study was performed analysing the platelet aggregation of patients treated with dabigatran or rivaroxaban with or without concomitant platelet inhibitors. Measurements before the initiation of NOAC therapy served as the respective control group. Platelet aggregation was measured by multiple electrode aggregometry and was induced with adenosine diphosphate (ADP, 6.5 µM) and arachidonic acid (AA, 0.5 mM), respectively. In order to evaluate whether NOACs interact with platelet inhibition by ASA or the P2Y12-antagonist clopidogrel, 87 patients were grouped according to their concomitant antiplatelet medication. Comparing the ADP- and AA-induced platelet aggregation in patients without concomitant platelet inhibitors (n = 45) no significant differences under therapy with dabigatran (d) or rivaroxaban (r) compared to the control group (c) were observed. In patients taking clopidogrel as a concomitant platelet inhibitor (n = 21), neither dabigatran nor rivaroxaban affected the ADP-induced platelet aggregation (c 20 ± 11, d 21 ± 14, r 18 ± 8 AU*min, p = 0.200). Patients receiving dabigatran or rivaroxaban in combination with ASA (n = 42; 21 ASA only, 21 ASA + clopidogrel) showed no significant differences of the AA

  13. CAPIRI-IMRT: a phase II study of concurrent capecitabine and irinotecan with intensity-modulated radiation therapy for the treatment of recurrent rectal cancer

    International Nuclear Information System (INIS)

    This study investigated the local effect and acute toxicity of irinotecan and capecitabine with concurrent intensity-modulated radiation therapy (IMRT) for the treatment of recurrent rectal cancer without prior pelvic irradiation. Seventy-one patients diagnosed with recurrent rectal cancer who did not previously receive pelvic irradiation were treated in our hospital from October 2009 to July 2012. Radiotherapy was delivered to the pelvis, and IMRT of 45 Gy (1.8 Gy per fraction), followed by a boost of 10 Gy to 16 Gy (2 Gy per fraction), was delivered to the recurrent sites. The concurrent chemotherapy regimen was 50 mg/m2 irinotecan weekly and 625 mg/m2 capecitabine twice daily (Mon-Fri). Radical surgery was recommended for medically fit patients without extra-pelvic metastases. The patients were followed up every 3 months. Tumor response was evaluated using CT/MRIs according to the RECIST criteria or postoperative pathological findings. NCI-CTC 3.0 was used to score the toxicities. Forty-eight patients (67.6%) had confirmed recurrent rectal cancer without extra pelvic metastases, and 23 patients (32.4%) had extra pelvic metastases. Fourteen patients (19.7%) underwent radical resections (R0) post-chemoradiation. A pathologic complete response was observed in 7 of 14 patients. A clinical complete response was observed in 4 patients (5.6%), and a partial response was observed in 22 patients (31.0%). Only 5 patients (7.0%) showed progressive disease during or shortly after treatment. Of 53 symptomatic patients, clinical complete and partial symptom relief with chemoradiation was achieved in 56.6% and 32.1% of patients, respectively. Only 2 patients (2.8%) experienced grade 4 leukopenia. The most common grade 3 toxicity was diarrhea (16 [22.5%] patients). The median follow-up was 31 months. The cumulative local progression-free survival rate was 74.2% and 33.9% at 1 and 3 years after chemoradiation, respectively. The cumulative total survival rate was 80.1% and 36

    This study evaluated safety & immunogenicity of ZOSTAVAX® (zoster vaccine: ZV) administered concomitantly versus nonconcomitantly with PNEUMOVAX® 23 (pneumococcal vaccine: PPV23). This randomized, double-blind, placebo-controlled study enrolled 473 subjects ≥60 years old in 1:1 ratio to receive ZV & PPV23 concomitantly (Day 1) or nonconcomitantly (PPV23 Day 1, ZV Week 4). Blood samples obtained for pneumococcal polysaccharide (PnPs) antibody (Ab) testing by enzyme-linked immunosorbent assay (ELISA) and varicella-zoster virus (VZV) Ab testing by glycoprotein ELISA. Subjects followed for adverse experiences (AEs) for 28 days postvaccination. Mean baseline VZV geometric mean titers (GMT) in nonconcomitant group were lower than concomitant group. Four weeks postvaccination with ZV, VZV Ab response in concomitant group was not similar to nonconcomitant group; estimated VZV GMT ratio [concomitant/nonconcomitant] was 0.70 (95% CI, 0.61-0.80). VZV Ab response was acceptable in concomitant group; estimated geometric mean foldrise (GMFR) from baseline was 1.9 (95% CI, 1.7-2.1). PnPs serotype-specific Ab responses were similar in both groups. All 6 reported serious AEs were deemed not related to study vaccine. Postvaccination of ZV, incidence of injection-site AEs was similar in both groups; clinical AEs were numerically but not significantly higher in nonconcomitant group. In summary, VZV GMT Ab response induced by ZV administered concomitantly with PPV23 was inferior to that induced nonconcomitantly. These results indicate that, to avoid a potential decrease in ZV immunogenicity, ZV & PPV23 should not be given concomitantly. Concomitant administration did not affect response to PPV23 serotypes tested. When administered concomitantly, ZV & PPV23 vaccines were generally well tolerated.

    Background: The objective of this study was to report a case series on the efficacy and safety of capecitabine 7/7 schedule combined with erlotinib (CAP-ERL) in patients with advanced pancreatic cancer (APC) who have failed prior therapies. Methods: We retrospectively evaluated 13 patients with locally advanced or metastatic pancreatic cancer previously treated with gemcitabine or oxaliplatin–irinotecan-based first-line regimens. Treatment consisted of capecitabine (Xeloda) at a flat dose of 1000 mg orally twice daily on days 1–7 out of 14 days (7/7 schedule) and erlotinib (Tarceva) 100 mg orally once daily until unacceptable toxicity or disease progression. Tumor assessments were repeated every two cycles (8 weeks) and serum tumor markers were measured every 4 weeks. Results: All patients (median age: 63 years; 7 female/3 male) had various previous lines of treatments of chemotherapies. Median number of cycles with CAP-ERL was 4 (range 2–12). The overall response rate was 20%. CA19-9 was reduced more than 25% in 40% patients. The median overall survival and progression-free survival from the start of CAP-ERL were 4.5 months (range 3–7.5) and 2 months (range 1.5–4), respectively. The most common grade 3 toxicities included hand–foot syndrome, nausea, vomiting, diarrhea, rash, and fatigue. Conclusions: Our result suggests that the combination of a fixed low dose of CAP-ERL 7/7 schedule was tolerated with manageable toxicity and showed encouraging activity as salvage treatment in patients with refractory APC with ECOG performance status 0–2. Further prospective studies are warranted to evaluate this combination. PMID:26929778

    Purpose: To evaluate, in a phase 2 study, the safety and efficacy of induction gemcitabine, oxaliplatin, and cetuximab followed by selective capecitabine-based chemoradiation in patients with borderline resectable or unresectable locally advanced pancreatic cancer (BRPC or LAPC, respectively). Methods and Materials: Patients received gemcitabine and oxaliplatin chemotherapy repeated every 14 days for 6 cycles, combined with weekly cetuximab. Patients were then restaged; “downstaged” patients with resectable disease underwent attempted resection. Remaining patients were treated with chemoradiation consisting of intensity modulated radiation therapy (54 Gy) and concurrent capecitabine; patients with borderline resectable disease or better at restaging underwent attempted resection. Results: A total of 39 patients were enrolled, of whom 37 were evaluable. Protocol treatment was generally well tolerated. Median follow-up for all patients was 11.9 months. Overall, 29.7% of patients underwent R0 surgical resection (69.2% of patients with BRPC; 8.3% of patients with LAPC). Overall 6-month progression-free survival (PFS) was 62%, and median PFS was 10.4 months. Median overall survival (OS) was 11.8 months. In patients with LAPC, median OS was 9.3 months; in patients with BRPC, median OS was 24.1 months. In the group of patients who underwent R0 resection (all of which were R0 resections), median survival had not yet been reached at the time of analysis. Conclusions: This regimen was well tolerated in patients with BRPC or LAPC, and almost one-third of patients underwent R0 resection. Although OS for the entire cohort was comparable to that in historical controls, PFS and OS in patients with BRPC and/or who underwent R0 resection was markedly improved.

    Purpose: To validate tolerance and pathological complete response rate (pCR) of a 4-week preoperative course of intensity-modulated radiation therapy (IMRT) with concurrent capecitabine and oxaliplatin (CAPOX) in patients with locally advanced rectal cancer. Methods and Materials: Patients with T3 to T4 and/or N+ rectal cancer received preoperative IMRT (47.5 Gy in 19 fractions) with concurrent capecitabine (825 mg/m{sup 2} b.i.d., Monday to Friday) and oxaliplatin (60 mg/m{sup 2} on Days 1, 8, and 15). Surgery was scheduled 4 to 6 weeks after the completion of chemoradiation. Primary end points were toxicity and pathological response rate. Local control (LC), disease-free survival (DFS), and overall survival (OS) were also analyzed. Results: A total of 100 patients were evaluated. Grade 1 to 2 proctitis was observed in 73 patients (73%). Grade 3 diarrhea occurred in 9% of the patients. Grade 3 proctitis in 18% of the first 50 patients led to reduction of the dose per fraction to 47.5 Gy in 20 treatments. The rate of Grade 3 proctitis decreased to 4% thereafter (odds ratio, 0.27). A total of 99 patients underwent surgery. A pCR was observed in 13% of the patients, major response (96-100% of histological response) in 48%, and pN downstaging in 78%. An R0 resection was performed in 97% of the patients. After a median follow-up of 55 months, the LC, DFS, and OS rates were 100%, 84%, and 87%, respectively. Conclusions: Preoperative CAPOX-IMRT therapy (47.5 Gy in 20 fractions) is feasible and safe, and produces major pathological responses in approximately 50% of patients.

    Full Text Available Objective. To evaluate whether HIV infected pregnant women with concomitant sexually transmitted infection (STIs are at increased risk of adverse perinatal and neonatal outcomes. Methods. We conducted a cohort study of HIV positive women who delivered at an inner-city hospital in Atlanta, Georgia, from 2003 to 2013. Demographics, presence of concomitant STIs, prenatal care information, and maternal and neonatal outcomes were collected. The outcomes examined were the association of the presence of concomitant STIs on the risk of preterm birth (PTB, postpartum hemorrhage, chorioamnionitis, preeclampsia, intrauterine growth restriction, small for gestational age, low Apgar scores, and neonatal intensive care admission. Multiple logistic regression was performed to adjust for potential confounders. Results. HIV positive pregnant women with concomitant STIs had an increased risk of spontaneous PTB (odds ratio (OR 2.11, 95% confidence interval [CI] 1.12–3.97. After adjusting for a history of preterm birth, maternal age, and low CD4+ count at prenatal care entry the association between concomitant STIs and spontaneous PTB persisted (adjusted OR 1.96, 95% CI 1.01–3.78. Conclusions. HIV infected pregnant women with concomitant STIs relative to HIV positive pregnant women without a concomitant STI are at increased risk of spontaneous PTB.

    Full Text Available We report a rare patient of a simultaneous extradural and intradural compression of the cervical spinal cord due to co-existent intervertebral disc herniation and an intradural schwannoma at the same level. The intradural lesion was missed resulting in recurrence of myelopathy after a surprisingly complete functional recovery following anterior cervical discectomy. Retrospectively, it was noted that the initial cord swelling noticed was tumor being masked by the compression produced by the herniated disc. A contrast magnetic resonance imaging scan is important in differentiating intradural tumors of the spinal cord. A high index of suspicion is often successful in unmasking both the pathologies.

Methods: All the patients with advanced gastric cancer who were not received any prior chemotherapy or radiotherapy were treated with combination of capecitabine (1250 mg/m2 twice daily, days 1-14) plus oxaliplatin (130 mg/m2 as a 2-h intravenous infusion on day 1) every 3 weeks. Results: Two cases of complete response (CR) and 34 cases of partial response (PR) were confirmed, giving an overall response rate of 52.9%, of the 68 patients with advanced gastric cancer. The median TTP and overall survival for all patients were 7.3 and 11.9 months, respectively. Grade 3 leukopenia, thrembocytopenia, nausealvomiting, and diarrhea were observed in 3, 5, 1, and 4 patients, respectively. Yet, no grade 4 toxicity was observed. Conclusion: Capecitabine/ oxaliplatin combination chemotherapy is active in patients with advanced gastric cancer.

  4. Concomitant septic arthritis and osteomyelitis of the hip in young children; a new pathophysiological hypothesis suggested by MRI enhancement pattern

    International Nuclear Information System (INIS)

    In children, septic arthritis (SA) of the hip is either primary or concomitant with acute haematogenous osteomyelitis (AHO). However, seldom, patients with isolated SA at presentation, may later show osteomyelitis in the metaphysis. The aim of this study was to elaborate a physiopathological hypothesis based on the peculiar MRI findings to explain the onset of AHO after SA. Cases of acute infection of the hip admitted between January 2010 and December 2013 were retrospectively reviewed to assess radiographic and MRI features, as well as bacteriological findings. Only children with isolated SA were included in this study, whereas cases of concomitant SA and AHO at presentation were excluded. Ten patients met the inclusion criteria. Six (1–11 months) demonstrated, on the initial MRI, decreased perfusion on gadolinium enhanced fat-suppressed T1-weighted sequence of the femoral epiphysis and developed one month later metaphyseal AHO. Four (5–14 years) did not show decreased perfusion and did not develop AHO on follow-up. The type of germ involved influenced neither the type of enhancement pattern nor the outcome. Age under one year and decreased perfusion of the affected femoral epiphysis increases the risk of secondary AHO. Our study is the first report in human medicine supporting the physiopathological hypothesis described by Alderson et al. in an animal model: primary infection can originally affect the joint, then penetrate the epiphyseal cartilage, and finally spread into the metaphyseal region through transphyseal vessels present only in the first 12/18 months of life

    This work aimed at investigating concomitant production of biohydrogen and poly-β-hydroxybutyrate (PHB) by photofermentation (PF) using dark fermentation effluents (DFE). An adapted culture of Rhodobacter sphaeroides AV1b (pH 6.5, 24±2°C) achieved H2 and PHB yields of 256 (±2) NmLH2/g Chemical Oxygen Demand (COD) and 273.8mgPHB/gCOD (32.5±3% of the dry cells weight (DCW)), respectively. When a diluted (1:2) DFE medium was applied to the adapted pure and mixed photofermentative culture, the respective H2 yields were 164.0 (±12) and 71.3 (±6) NmLH2/gCOD and the PHB yields were 212.1 (±105.2) and 50.7 (±2.7) mgPHB/gCOD added, corresponding to 24 (±0.7) and 6.3 (±0) % DCW, respectively. The concomitant H2 and PHB production from the PF process gave a good DFE post treatment achieving up to 80% COD removal from the initial DFE. PMID:27005789

    Full Text Available Double pylorus (DP is a rare condition that is usually discovered incidentally through an upper endoscopy (UE examination. While acquired DP, which is the most common type, often develops as a complication of peptic ulcer disease (PUD, congenital DP can be isolated associated with other congenital abnormalities such as heterotopic pancreatic tissue or gastric duplication [1, 2]. This article presents the first case of DP associated with pancreas divisum (PD. A twenty two-year-old woman was admitted to our hospital because of mild epigastric pain. Her medical history was unremarkable. The laboratory tests that were requested on admission were normal except for amylase 920 U/L (reference range: 60-180 U/L.The patient denied having had any history of PUD or of having used nonsteroidal anti-inflammatory drugs (NSAIDs. A UE examination revealed two pyloric openings into the duodenal bulb. However, there was no evidence of PUD on the UE. The presence of Helicobacter pylori was not observed in the histologic examination of the gastric antrum tissue. Magnetic resonance cholangiopancreatogram (MRCP imaging showed PD (Figure 1 A-B. The patient was treated symptomatically, and she recovered. When the UE and MRCP were repeated for control on the sixth month of the treatment, they demonstrated the same findings as the initial UE and MRCP.

    Full Text Available Background. The coexistence of neoplasm and abdominal aortic aneurysm (AAA presents a real management challenge. This paper reviews the literature on the prevalence, diagnosis, and management dilemmas of concurrent visceral malignancy and abdominal aortic aneurysm. Method. The MEDLINE and HIGHWIRE databases (1966-present were searched. Papers detailing relevant data were assessed for quality and validity. All case series, review articles, and references of such articles were searched for additional relevant papers. Results. Current challenges in decision making, the effect of major body-cavity surgery on an untreated aneurysm, the effects of major vascular surgery on the treatment of malignancy, the use of EVAR (endovascular aortic aneurysm repair as a fairly low-risk procedure and its role in the management of malignancy, and the effect of other challenging issues such as the use of adjuvant therapy, and patients informed decision-making were reviewed and discussed. Conclusion. In synchronous malignancy and abdominal aortic aneurysm, the most life-threatening lesion should be addressed first. Endovascular aneurysm repair where possible, followed by malignancy resection, is becoming the preferred initial treatment choice in most centres.

Methods: We present a case of herpes simplex virus colitis and hepatitis, review all the previously published cases of herpes simplex virus colitis, and discuss common clinical features and outcomes. We also discuss the epidemiology, clinical manifestations, diagnosis, and management of herpes simplex virus infections, focusing specifically on patients with inflammatory bowel disease. Results: A 43-year-old man with ulcerative colitis, previously controlled with an oral 5-aminosalicylic agent, developed symptoms of a colitis flare that did not respond to treatment with systemic corticosteroid therapy. One week later he developed orolabial ulcers and progressive hepatic dysfunction, with markedly elevated transaminases and coagulopathy. He underwent emergent total colectomy when imaging suggested bowel micro-perforation. Pathology from both the colon and liver was consistent with herpes simplex virus infection, and a viral culture of his orolabial lesions and a serum polymerase chain reaction assay also identified herpes simplex virus. He was treated with systemic antiviral therapy and made a complete recovery. Conclusions: Disseminated herpes simplex virus infection with concomitant involvement of the colon and liver has been reported only 3 times in the published literature, and to our knowledge this is the first such case in a patient with inflammatory bowel disease. The risk of invasive herpes simplex virus infections increases with some, but not all immunomodulatory therapies. Optimal management of herpes simplex virus in patients with inflammatory bowel disease includes targeted prophylactic therapy for patients with evidence of latent infection, and timely initiation of antiviral therapy for those patients suspected to have invasive disease.

  11. Maximum Inhibition of Breast Cancer/Stem Cell Growth by Concomitant Blockage of Key Receptors

    Full Text Available The blockage of cancer cell growth and division is the prime objective in clinical cancer therapy both at early stages and for inhibition of minimal residual disease and relapse. The failure of conventional therapies in treating breast cancer (BC has prompted dissection of signalling pathways involved in BC cell growth and characterisation of cellular receptors. Specific sets of membrane-bound receptors promote disarrayed self-renewal of BC stem cells and deregulated BC cell proliferation. Individual blockage of each receptor promotes only incomplete inhibition of BC cell growth and partial regression of metastasis. Such monotherapies are based on either chemotherapy or monoclonal antibodies. However, they do not provide long-lasting benefits and are further compromised by increasing resistance the cancer cells acquire against therapeutic agents, by their evasion of receptor blockage and by adoption of alternative growth routes that are induced by cross-talks between key receptors. On the other hand, dual targeting approaches, including receptor blockage combined with chemotherapy, produce prolonged overall survival but, nevertheless, complicate treatment by inducing side effects. Based on the complex nature of BC, combined targeted strategies that potentially confer maximum coverage for treatment cannot be effective without overcoming drug resistance initiated and further induced by inter-receptor communications. This implies that a comprehensive strategy based on concomitant inhibition of key receptors could provide an ultimate solution for effective treatment of aggressive types of BC. Such a strategy would likely be capable of targeting breast tumour cells and BC stem cells alike eventually forcing the cancer to regress.

    Purpose: To evaluate the safety, efficacy and biomarkers of short-course proton beam radiation and capecitabine, followed by pancreaticoduodenectomy in a phase 1/2 study in pancreatic ductal adenocarcinoma (PDAC) patients. Methods and Materials: Patients with radiographically resectable, biopsy-proven PDAC were treated with neoadjuvant short-course (2-week) proton-based radiation with capecitabine, followed by surgery and adjuvant gemcitabine. The primary objective was to demonstrate a rate of toxicity grade ≥3 of <20%. Exploratory biomarker studies were performed using surgical specimen tissues and peripheral blood. Results: The phase 2 dose was established at 5 daily doses of 5 GyE. Fifty patients were enrolled, of whom 35 patients were treated in the phase 2 portion. There were no grade 4 or 5 toxicities, and only 2 of 35 patients (4.1%) experienced a grade 3 toxicity event (chest wall pain grade 1, colitis grade 1). Of 48 patients eligible for analysis, 37 underwent pancreaticoduodenectomy. Thirty of 37 (81%) had positive nodes. Locoregional failure occurred in 6 of 37 resected patients (16.2%), and distant recurrence occurred in 35 of 48 patients (72.9%). With median follow-up of 38 months, the median progression-free survival for the entire group was 10 months, and overall survival was 17 months. Biomarker studies showed significant associations between worse survival outcomes and the KRAS point mutation change from glycine to aspartic acid at position 12, stromal CXCR7 expression, and circulating biomarkers CEA, CA19-9, and HGF (all, P<.05). Conclusions: This study met the primary endpoint by showing a rate of 4.1% grade 3 toxicity for neoadjuvant short-course proton-based chemoradiation. Treatment was associated with favorable local control. In exploratory analyses, KRAS{sup G12D} status and high CXCR7 expression and circulating CEA, CA19-9, and HGF levels were associated with poor survival.

  13. Role of concomitant therapy for Helicobacter pylori eradication: A technical note

    We read with interest the recent meta-analysis by Lin et al who evaluated the effectiveness of concomitant regimen for Helicobacter pylori (H. pylori) in Chinese regions. They found that 7-d concomitant regimen is undoubtedly superior to 7-d triple therapy (91.2% vs 77.9%, P < 0.0001). However, it is a common belief that a triple therapy lasting 7 d should be definitively removed from the clinical practice for its ineffectiveness. Only its prolongation to 14 d may give satisfactory success rate. Thus, the assessment of an old and outdated treatment versus a more recent and successful one does not seem to bring novel and useful information. Moreover, a 7-d duration has not been ascertained for concomitant regimen, as main guidelines recommend a 10-d schedule for this scheme. Therefore, only studies comparing 10-d concomitant versus 14-d triple seem to be appropriate according to current Guidelines and would clarify which regimen is the most suitable worldwide. Additionally, in this meta-analysis concomitant and sequential therapy showed similar performances, despite it is common opinion that sequential is more prone than concomitant therapy to fail when metronidazole resistance occurs, and China is characterized by high rate of resistance to this antibiotic. None of the included studies evaluated a priori antibiotic resistances, and the lack of this detail hampers the unveiling of this apparent contradiction. In conclusion, the lack of the evaluation of the quality of included trials as well as their high heterogeneity constitute a burdensome limit to draw solid conclusions in this meta-analysis. On the bases of these considerations and the low number of examined trials, we believe that further studies and the knowledge of antibiotic resistances will support with high quality evidence which is the best regimen and its optimal duration.

    The study found that the 7 d of concomitant therapy (lansoprazole, amoxicillin, clarithromycin and metronidazole) achieved significantly higher eradication rates compared to 7 d of triple therapy (lansoprazole, amoxicillin, clarithromycin), the intention to treat (ITT) cure rates being 94.9% and 68.3%, respectively. According to our opinion, this study is clinically relevant for Japanese physicians for at least 2 reasons: (1) the standard triple therapy (clarithromycin plus amoxicillin) achieved disappointing cure rates in Japan-in agreement with what was observed in several countries; and (2) the concomitant quadruple therapy is an effective therapeutic alternative.

    Objective:The aim of our study was to compare the ef icacy and toxicities of vinorelbine plus cisplatin (NP) regimen with that of vinorelbine plus capecitabine (NX) regimen in the treatment of anthracycline- and taxane-refractory advanced breast cancer. Methods:Forty-six patients with anthracycline-and taxane-refractory advanced breast cancer were equal y randomized into a NP group (n=23) and a NX group (n=23). Response rates and toxicities were evaluated after 2 cycles of chemotherapy. Results:The overal response rate were 48.0%in both groups. There were no significant dif erences in disease control rates (78.0%vs. 83%) or 1-year survival rates (54.6%vs. 55.9%). The main adverse events were bone marrow depression and gastrointestinal reaction, and no significant dif erence was found in toxicities between the groups. Conclusion:For anthracycline-and taxane-refractory advanced breast cancer, NP and NX regimens exerted similar curative ef ects with acceptable toxicity.

  18. Daily low-dose/continuous capecitabine combined with neo-adjuvant irradiation reduces VEGF and PDGF-BB levels in rectal carcinoma patients

    International Nuclear Information System (INIS)

    Metronomic low-dose chemotherapy regimen was found to have an antiangiogenic effect in tumors. However, its effect on levels of circulating pro-angiogenic and anti-angiogenic factors is not fully explored. Materials and methods. The levels of both VEGF and PDGF-BB were measured in three time points, in the serum of 32 rectal carcinoma patients receiving daily reduced-dose/continuous capecitabine in combination with preoperative pelvic irradiation. Results. We found a significant decrease in VEGF and PDGF-BB serum levels during the combination treatment (p<0.0001), followed by an increase in the successive rest-period (p<0.0001). In addition, substantial changes in platelets counts were observed during treatment in correlation with the changes of VEGF and PDGF-BB serum levels. Discussion. These results suggest that combined chemo-irradiation affect levels of pro-angiogenic factors during treatment, and may reflect an anti-angiogenic window induced during this treatment. The potential implications of this inducible phenomenon, including a possible clinical benefit from the administration of long lasting metronomic chemotherapy immediately following combined chemo-irradiation, would warrant further investigation

  20. Timing of pilocarpine treatment during head and neck radiotherapy: concomitant administration reduces xerostomia better than post-radiation pilocarpine

    International Nuclear Information System (INIS)

    Purpose: To study whether oral pilocarpine administration during and three months after head and neck radiotherapy can prevent or reduce the expected post-radiation xerostomia. This regimen was compared to no treatment and to post-radiotherapy pilocarpine administration, which has previously been shown to reduce symptoms of xerostomia in several randomized trials. Methods: Xerostomia assessments were performed using a visual analog scale xerostomia questionnaire that measures oral dryness, oral comfort, difficulty with sleep, speech and eating. Higher scores indicate less xerostomia. All the patients had all major salivary glands in the initial field treated to ≥ 4,500 cGy. The concomitant pilocarpine group received 5 mg pilocarpine q.i.d. beginning on day one of radiotherapy and continuing for 3 months after completion of radiation. The control group had their baseline xerostomia measured prior to receiving pilocarpine. They subsequently took 5 mg pilocarpine t.i.d. for one month at which time they underwent a second xerostomia assessment. Xerostomia scores for each group were averaged and compared using the Student's t-test. Results: Seventeen patients who received pilocarpine during head and neck irradiation were compared to 12 post-radiotherapy patients who had not yet taken pilocarpine and the same patients after taking pilocarpine for one month. The mean intervals between completion of radiation and evaluation of xerostomia were 16 months for the control group and 17 months for the pilocarpine treated groups. The primary tumor sites treated as well as the total tumor doses were equivalent between the groups. Only one of the pilocarpine treated patients was still taking pilocarpine at the time of evaluation. Results are shown. For each component of xerostomia measured as well as the composite of all components, the group that had received pilocarpine during radiation had significantly less xerostomia than the no pilocarpine group (p<0.01 for each).

    Backgrounds/Aims Aggressive surgical resection for hepatic metastasis is validated, however, concomitant liver and lung metastasis in colorectal cancer patients is equivocal. Methods Clinicopathologic data from January 2008 through December 2012 were retrospectively reviewed in 234 patients with colorectal cancer with concomitant liver and lung metastasis. Clinicopathologic factors and survival data were analyzed. Results Of the 234 patients, 129 (55.1%) had synchronous concomitant liver and lung metastasis from colorectal cancer and 36 (15.4%) had metachronous metastasis. Surgical resection was performed in 33 patients (25.6%) with synchronous and 6 (16.7%) with metachronous metastasis. Surgical resection showed better overall survival in both groups (synchronous, p=0.001; metachronous, p=0.028). In the synchronous metastatic group, complete resection of both liver and lung metastatic lesions had better survival outcomes than incomplete resection of two metastatic lesions (p=0.037). The primary site of colorectal cancer and complete resection were significant prognostic factors (p=0.06 and p=0.003, respectively). Conclusions Surgical resection for hepatic and pulmonary metastasis in colorectal cancer can improve complete remission and survival rate in resectable cases. Colorectal cancer with concomitant liver and lung metastasis is not a poor prognostic factor or a contraindication for surgical treatments, hence, an aggressive surgical approach may be recommended in well-selected resectable cases.

  6. Radiotherapy with concomitant carboplatin (CBDCA) vs cisplatin (CDDP) and superselective arterial infusion of decadose CDDP

    International Nuclear Information System (INIS)

    We compared the effectiveness between carboplatin (CBDCA) and cisplatin (CDDP) as a single-agent chemotherapy and concomitant radiotherapy in operable head and neck cancer by a prospective randomized trial. The CBDCA-treated group (n=60) showed significantly better 5-year local control rate (56.2%) than the CDDP-treated group (n=59, 35.5%, p=0.03). There was no difference in toxicities, which were considered acceptable. We suggest choosing weekly CBDCA rather than daily low-dose CDDP as a chemotherapeutic agent for concomitant chemoradiotherapy in patients with operable cancer, although a dose of CDDP may be too small. Superselective arterial infusion for patients with advanced head and neck cancer has increasingly applied in Japan. We analyzed our experiences and evaluated the efficacy and safety of this treatment. Twenty nine patients received superselective intra-arterial infusion therapy of cisplatin (100-120 mg/m2/week) and conventional concomitant extrabeam radiotherapy. Two year overall survival rate was 42.9%. The primary lesions were well controlled in 21 patients (72.4%). High-frequent acute toxic effects were leukopenia and mucositis. Severe toxic events occurred in three cases, namely, methicillin-resistant Staphylococcus aureus (MRSA) pneumonia, sepsis, and tetraplasia. We confirmed the effectiveness and safety of superselective arterial infusion and concomitant radiotherapy. Furthermore, we must establish the optimal procedures and schedule, as well as the indications for this treatment. This treatment protocol expected the cure of patients with unresectable disease and patients rejecting surgical treatment. (author)

    Purpose: To investigate the value of endovenous laser ablation (ELA) and concomitant ultrasound-guided foam sclerotherapy (USGFS) in patients with chronic venous insufficiency. Methods: During a 6-year period, concomitant USGFS of the varicose veins were performed in 504 out of 610 patients who underwent ELA for truncal or perforating vein insufficiency. In these 504 patients (944 legs; bilateral in 440 patients), the incompetent veins were greater saphenous vein in 615 legs, small saphenous vein in 118 veins, perforating veins in 42 legs, and a combination of these in 169 legs. In all patients, after ELA of the incompetent veins, USGFS was performed for the remaining varicosities with 1-3% polidocanol foam. Patients were followed up clinically and with color Doppler ultrasound at 1, 6, and 12 months. Results: ELA was technically successful in all cases, although another venous puncture was necessary in 29 legs. Concomitant USGFS was also technically successful in all cases, but one to three additional sclerotherapy sessions were performed in 203 legs with persistent varicosities. During the follow-up, recanalization of the laser-ablated refluxing veins occurred in 16 legs (1.7%) and was treated with repeat ELA or USGFS. Major complications occurred in 1.4% of the treated legs and included skin necrosis and calf vein thrombosis. Conclusion: ELA and concomitant foam sclerotherapy is feasible and effective. The procedures are associated with a low complication rate and can be performed in both legs in the same session. Concomitant use of laser and foam may potentially decrease the recanalization rate of laser-ablated vessels.

    Full Text Available Abstract Background MicroRNA-126 is the only microRNA (miRNA known to be endothelial cell-specific influencing angiogenesis in several ways. The aim of the present study was to analyse the possible predictive value of miRNA-126 in relation to first line capecitabine and oxaliplatin (XELOX in patients with metastatic colorectal cancer (mCRC. Methods The study included 89 patients with mCRC. In situ hybridization (ISH was performed to detect miRNA-126 in formalin-fixed paraffin embedded tissue from primary tumours. The expression of miRNA-126, area per image (μm2, was measured using image analysis. Clinical response was evaluated according to RECIST. Progression free survival (PFS was compared using the Kaplan-Meier method and the log rank test. Tumours were classified as low or high miRNA-126 expressing tumours using the median value from the patients with response as cut-off. Results The median miRNA-126 expression level was significantly higher in patients responding to XELOX, 3629 μm2 (95% CI, 2566-4846, compared to the patients not responding, 1670 μm2 (95% CI, 1436-2041, p p Conclusions Angiogenesis quantified by ISH of miRNA-126 was related to response to first line XELOX in patients with mCRC, translating to a significant difference in PFS. The predictive value of miRNA-126 remains to be further elucidated in prospective studies.

    Capecitabine (Cap) is an often prescribed chemotherapeutic agent, successfully used to cure some patients from cancer or reduce tumor burden for palliative care. However, the efficacy of the drug is limited, it is not known in advance who will respond to the drug and it can come with severe toxicity. (19)F Magnetic Resonance Spectroscopy (MRS) and Magnetic Resonance Spectroscopic Imaging (MRSI) have been used to non-invasively study Cap metabolism in vivo to find a marker for personalized treatment. In vivo detection, however, is hampered by low concentrations and the use of radiofrequency (RF) surface coils limiting spatial coverage. In this work, the use of a 7T MR system with radiative multi-channel transmit-receive antennas was investigated with the aim of maximizing the sensitivity and spatial coverage of (19)F detection protocols. The antennas were broadband optimized to facilitate both the (1)H (298 MHz) and (19)F (280 MHz) frequencies for accurate shimming, imaging and signal combination. B1(+) simulations, phantom and noise measurements showed that more than 90% of the theoretical maximum sensitivity could be obtained when using B1(+) and B1(-) information provided at the (1)H frequency for the optimization of B1(+) and B1(-) at the (19)F frequency. Furthermore, to overcome the limits in maximum available RF power, whilst ensuring simultaneous excitation of all detectable conversion products of Cap, a dual-band RF pulse was designed and evaluated. Finally, (19)F MRS(I) measurements were performed to detect (19)F metabolites in vitro and in vivo. In two patients, at 10 h (patient 1) and 1 h (patient 2) after Cap intake, (19)F metabolites were detected in the liver and the surrounding organs, illustrating the potential of the set-up for in vivo detection of metabolic rates and drug distribution in the body.

    Full Text Available Objective: To report two cases of concomitant choroidal melanoma and intraocular non-Hodgkin lymphoma in two patients. Design: Case report. Participants: Two patients with yellow creamy infiltrates in fundo. Intervention: Both patients had a complete ophthalmologic evaluation and histology was obtained after enucleation of the affected eye. Main Outcome Measures: Histology findings of the enucleated eyes. Results: One patient showed a choroidal melanoma with a primary non-Hodgkin lymphoma located solely in the affected eye. The other patient showed a systemic non-Hodgkin lymphoma with ocular manifestations concomitant with a choroidal melanoma. Conclusions: In the presence of yellow creamy infiltrates one should include a choroidal lymphoma in the differential diagnosis even if there is another clear pathologic condition. Furthermore in those cases systemic disease should be excluded.

    We predict, for the first time, that by using United States Food and Drug Administration approved concentrations of cisplatin, major radiosensitization may be achieved via photoelectric mechanism during concomitant chemoradiotherapy (CCRT). Our analytical calculations estimate that radiotherapy (RT) dose to cancer cells may be enhanced via this mechanism by over 100% during CCRT. The results proffer new potential for significantly enhancing CCRT via an emerging clinical scenario, where the cisplatin is released in-situ from RT biomaterials loaded with cisplatin nanoparticles.

  2. The effect of concomitant chemotherapy on parotid gland function following head and neck IMRT

    International Nuclear Information System (INIS)

    Purpose: To determine whether concomitant chemotherapy increases the incidence of high grade xerostomia following parotid-sparing intensity-modulated radiotherapy (IMRT) in patients with locally advanced head and neck squamous cell cancer. Materials and methods: The incidence of high grade (⩾G2) acute (CTCAEv3.0) and late (LENTSOMA and RTOG) xerostomia was compared between patients treated with either IMRT or concomitant chemo-IMRT (c-IMRT) in 2 prospective studies. Parotid gland mean tolerance doses (D50) were reported using non-linear logistic regression analysis. Results: Thirty-six patients received IMRT alone and 60 patients received c-IMRT. Patients received 65 Gy in 30 daily fractions to the primary site and involved nodal groups and 54 Gy in 30 fractions to elective nodal groups, mean doses to the parotid glands were comparable. Concomitant cisplatin 100 mg/m2 was administered on days 1 and 29 of IMRT. The incidence of ⩾G2 subjective xerostomia was similar in both groups; acute-64.7% (IMRT) versus 60.3% (c-IMRT), p = 0.83; late-43% (IMRT) versus 34% (c-IMRT), p = 0.51. Recovery of parotid salivary flow at 1 year was higher with IMRT (64% vs 50%), but not statistically significant (p = 0.15). D50 for absence of parotid saliva flow at 1 year was 23.2 Gy (95% CI: 17.7–28.7) for IMRT and 21.1 Gy (11.8–30.3) for c-IMRT. Conclusion: Concomitant c-IMRT does not increase the incidence of acute or late xerostomia relative to IMRT alone

  5. Concomitant chemotherapy and radiotherapy in the adjuvant treatment of breast cancer

    International Nuclear Information System (INIS)

    The conventional treatment of localized breast cancer involves the use of both systemic therapy and loco-regional radiation after surgery. The ideal sequence of these two treatments is still undefined. This paper focus on our experience of concomitant chemotherapy (CT) and radiotherapy (RT), and discusses information from the literature about this issue. Between Jan,1989 and Jan, 1999 a retrospective analysis of 103 patients with ductal carcinoma of the breast who received concomitant CT with cyclophosphamide, methotrexate and 5 flurouracil (CMF) and RT was made. Radiation did not included mammary chain or axilla and total dose was of 50 Gy. End points were tolerance and oxicity leading changes to doses. Mean age was 44y; median follow up time of 33 mo; 62 patients had breast conserving surgery and 41 had mastectomy. All patients received both treatments without a break or dose modification. There was no change or interruption of RT. Ten out of 103 patients had the prescribed dose of CT decreased of 10%-20%. There was no evident changes in cosmetic results. Most of the knowledge regarding the delay of CT or RT comes from retrospective studies, and results are conflicting. It is well accepted that high risk patients need both CT and RT. However, there are data suggesting that giving RT first and CT after may increase the rate of distant metastases. There are also studies showing worse impact in the local control with the delay of radiotherapy. The use of concomitant chemotherapy and radiotherapy has apparent advantages, but no randomized trial has addressed this issue yet. Our experience has shown that is possible to give concomitant CT with CMF and RT without irradiation of IMC and axilla without major changes in scheduling or dose of both therapies. (author)

    Management in patients with coexisting coronary artery disease and lung carcinoma is usually a two-stage operation, with the cardiac surgery procedure followed by pulmonary resection at a later time. Delayed tumor resection on the other hand may be detrimental. Off-pump coronary artery bypass grafting could facilitate concomitant lung resection at one stage via median sternotomy. T-bar retractor may be a useful tool in the surgical approach of this combined operation.

    Background and purpose: Capecitabine, which is widely used in the first-line treatment of advanced breast cancer, was known little in the maintenance treatment of advanced breast cancer. The present study aimed to explore the efficacy and safety of capecitabine in the maintenance treatment of advanced breast cancer. Methods: A total of 62 advanced breast cancer patients confirmed by histopathology and/or cytology, who had been evaluated as CR/PR/SD after first-line treatment, were divided into two groups. Thirty-one of them received capecitabine orally as maintenance treatment, while the others were followed up without any treatment. The clinical response was evaluated every two cycles. Results:The median time to progression (TTP) of the capecitabine group was 12 (2-24) months, which was signiifcantly higher than the control group. In the subgroup analysis, similar results were detected in the premenopausal group, hormone receptor positive group, HER-2 positive group, metastasis group, no capecitabine used history group. Among the capecitabine group,the overall response rate (CR+PR) was 19.4%, and the disease control rate (CR+PR+SD) was 74.2%. The most common adverse effects were hand-foot syndrome, hematologic toxicity and gastrointestinal reaction, all of which could be tolerated. The overall score of the capecitabine group evaluated by the Chinese vesion of the FACT-B was signiifcantly higher than the control group. Conclusion:Capecitabine can effectively and tolerably prolong survival time and improve the quality of life of patients in the maintenance treatment of advanced breast cancer.%背景与目的:卡培他滨是晚期乳腺癌一线治疗方案用药,但在晚期乳腺癌的维持治疗中的研究较少。本文旨在探讨卡培他滨维持治疗晚期乳腺癌的疗效及不良反应。方法:将一线化疗后处于完全缓解(complete response,CR)、部分缓解(partial response,PR)或疾病稳定(stable disease,SD)的62例患者分为2

    The term gastrointestinal stromal tumors (GISTs)is defined diagnostically as the main group of mesenchymal tumors with spindle or epithelioid cells arising from the wall of the gastrointestinal tract with immunohistochemical reactivity for CD117 antibody.Previous studies revealed that cells in GISTs express a growth factor receptor with tyrosine kinase activity (termed c-kit), which is the product of the c-kit protooncogene. The most specific and practical diagnostic criteria for GISTs are: immunohistochemically determined c-kit (CD117) expression; mitotic score; and tumor size.A small GIST concomitant with early gastric cancer is rarely encountered clinically. Herein we have reported a case of a 1.1-cm GIST detected by esophagogastroduo denoscopy concomitant with a Ⅱc type of early gastric cancer (signet ring cell type). It was detected during a routine physical health examination. To our knowledge,this is the first report of a small GIST concomitant with a signet ring cell type of early gastric cancer.

    Full Text Available Objective: To evaluate the concomitant systemic diseases with postmenopausal osteoporosis and to investigate the points to be considered in treatment approach of patients with osteoporosis. Materials and Methods: The study included 110 female patients admitted to our clinic and followed up after postmenopausal osteoporosis diagnosis. Besides the demographic data; the concomitant diseases of the patients such as hypertension, hypo-hyperthyroidism, diabetes mellitus, Alzheimer’s disease, malignancy, osteoarthritis, gastrointestinal system diseases, chronic obstructive pulmonary disease (COPD- asthma and depression were also recorded. Results: The mean age of the patients included in our study was 65.9±9.8 years. When the concomitant systemic diseases were examined; 40 patients had hypertension, 32 patients had osteoarthritis, 24 patients had gastrointestinal tract problems, 22 patients had thyroid disease, 21 patients had depression, 15 patients had hyperlipidemia, 12 patients had diabetes mellitus, 10 patients had COPD - asthma, 7 patients had cardiac diseases, 5 patients had malignancy and 2 patients had Alzheimer disease. Conclusion: Osteoporosis is a common disease in the geriatric population. As a chronic disease with an increasing incidence with aging; it can cause many health problems, prevalently pathological bone fractures, in our country and all over the world. Constitutively, prophylaxis of osteoporosis should be the first step. Because systemic diseases with increasing incidence with aging may affect the severity of osteoporosis and impair the treatment; it is important for both clinicians and the society to have sufficient information about osteoporosis.

    Full Text Available Introduction: There are many adverse effects that have been described for isotretinoin. To the best of our knowledge, this is the first report of a possible association of oral isotretinoin intake with autoimmune thyroiditis and ocular myasthenia gravis (OMG. Case Presentation: A 19-year-old Caucasian male, who had used oral isotretinoin for severe acne disease for the previous six months, was referred to our clinic. He had a three-week history of diplopia and variable bilateral ptosis. Physical examination showed moderate periorbital edema and limitations of up- and down-gaze in the left eye. Laboratory findings and thyroid ultrasound were consistent with autoimmune thyroiditis. Antithyroid therapy did not relieve the clinical symptoms. Concomitant OMG was suspected. Variable ptosis and a positive response to oral prednisolone of 40 mg/day and pyridostigmine of 360 mg/day supported the diagnosis of concomitant autoimmune thyroiditis and OMG. Conclusion: Autoimmune disorders may be triggered by oral isotretinoin treatment. Clinicians prescribing isotretinoin should be aware of the possible association between isotretinoin intake and concomitant autoimmune thyroiditis and OMG.

    Full Text Available Toxic epidermal necrolysis (TEN is a rare but life-threatening acute mucacutaneous hypersensitivity reaction, usually related to medications. Concomitant use of lamotrigine and valproic asid can cause this serious reaction. A 36 year-old-man admitted to emergency department with high fever, burning sensation at eyes, oral and genital mucous erosions, generalized rush and weakness. He had been taking valproic asid, olanzapine, and sertraline for bipolar affective disorder. Lamotrigine 25 mg/day treatment was added his treatment protocol 15 days ago before the rush and lamotgine dose was increased 50 mg/day 10 days later. The patient was diagnosed as TEN caused by concomitant use of valproic asid and lamotrigine. The patient followed up and treated at burn unit with intravenous immunoglobulin, corticosteroid and antibiotics. Concomitant use of valproic asid and lamotrigine increases the frequency of adverse reaction. TEN may cause serious complications and mortality. The patients with TEN should be followed by a multi-disciplinary team. Early determination of complications and suitable management can increase survival.

    Congestion is a major problem in most cities and the problem is growing (Quiroga, 2000) (Faghri & Hamad, 2002). When the congestion level is increased the drivers notice this as delays in the traffic (Taylor, Woolley, & Zito, 2000), i.e., the travel time for the individual driver is simply...... increased. In the initial study presented here, the time it takes to pass an intersection is studied in details. Two major signal-controlled four-way intersections in the center of the city Aalborg are studied in details to estimate the congestion levels in these intersections, based on the time it takes...

    2013-01-01

    Full Text Available Duplication of the lower urinary tract is a very rare congenital anomaly which is diagnosed either at birth or during early childhood. These rare malformations are most of the times accompanied by other concomitant anomalies and are therefore diagnosed immediately after birth. In some even rarer cases there are no concomitant anomalies and symptoms thus leading to a diagnosis later in childhood. This is the first case in the literature of complete bladder duplication in the coronal plane with concomitant duplication of the urethra and no other associated anomalies in a 52-year-old male who remained asymptomatic and therefore undiagnosed for more than 5 decades.

    OBJECTIVE: To observe efficacy and toxic side effect of capecitabine combined with cisplatin in the treatment of triple negative advanced breast cancer of negative ER, PR, HER-2. METHODS: 48 cases were diagnosed as advanced metastatic breast cancer of negative ER, PR, HER-2 by immunohistochemistry, among which 24 cases received oral dose of capecitabine 2 500 mg·m-2 alone morning and night for consecutive 14 days, 21 days for the 1 cycle; other 24 cases received capecitabine combined with cisplatin DDP: intravenous infusion of 30 cisplatin mg·m-2, d1~d3, oral dose of capecitabine in 1 250 mg·m-2 morning and night for consecutive 14 days, 21 days for the 1 cycle. The number of completed treatment course in monotherapy group and chemotherapy group were (4.2 + 0.9) and (4.0 + 0.7). RESULTS:The effective rates of capecitabine monotherapy group and chemotherapy group were 29.2% and 33.4%. The median TTP of 24 patients in monotherapy group was 5 months with 1 year survival rate of 65.7%. The median TTP of 24 patients in chemotherapy group was 6 months with 1 year survival rate of 67.7%. The Ⅲ -degree hand-foot syndrome of capecitabine monotherapy group was slightly more than combination group. Toxic side effect of chemotherapy group were mainly gastrointestinal tract reaction, leucopenia, fatigue, etc., and all recovered after proper treatment. CONCLUSION: Capecitabine combined with cisplatin have good efficacy in the treatment of advanced metastatic triple negative breast cancer patients, and toxic side effects can be tolerated.%目的:观察卡培他滨联合顺铂治疗雌激素受体(ER)、孕激素受体(PR)、人表皮生长因子受体2(HER-2)均阴性(三阴性)晚期乳腺癌的疗效与毒副反应.方法:48例经免疫组化证实ER、PR、HER-2阴性的晚期转移性乳腺癌患者,其中24例患者单用卡培他滨2500mg·m-2,分早晚两次口服,连服14d,21d为1个周期;24例患者接受卡培他滨+顺铂方案:顺铂30mg·m-2静脉滴注,d1

  4. Effects of Treatment Duration During Concomitant Chemoradiation Therapy for Cervical Cancer

    International Nuclear Information System (INIS)

    Purpose: To determine whether extended treatment duration (TD) impacts in-field relapse and survival in the setting of concomitant chemoradiation therapy (CRT) for cervical cancer. Methods and Materials: A total of 480 consecutive cervical cancer patients treated with radiation therapy (RT) alone or concomitant CRT for curative intent were retrospectively analyzed. Relapse was defined as in-field with respect to external beam radiation therapy fields. The effects of TD on in-field relapse, disease-free survival (DFS), and overall survival (OS) rates were assessed continuously and categorically within the separate RT and CRT cohorts. Covariates included age, histology, stage, and cumulative dose to point A. In-field relapse, DFS, and OS rates were estimated with Kaplan-Meier analysis; comparisons used log–rank statistic. Multivariate analysis used the Cox proportional hazards model. Results: A total of 372 patients (RT n=206, CRT n=166) were evaluable, with a median follow-up for relapse-free patients of 4.2 years (RT 4.4 years, CRT 4.2 years; P=.807). Treatment duration was longer in the RT cohort (median 55 days; range 35-99 days) versus the CRT cohort (median 51 days; range 35-92 days) (P=.001). In the RT cohort, TD ≥62 days trended to significance for predicting inferior DFS (hazard ratio 1.42, 95% confidence interval 0.86-1.98, P=.086). However, in the CRT cohort, TD assessed continuously or categorically across multiple cutoff thresholds did not predict for in-field relapse, DFS, or OS. Conclusion: With RT alone, extended TD ≥62 days may adversely impact treatment efficacy. With the addition of concomitant chemotherapy to RT, however, extended TD has no effect on treatment efficacy

  5. Adjuvant radiotherapy and concomitant 5-fluorouracil by protracted venous infusion for resected pancreatic cancer

    International Nuclear Information System (INIS)

    Purpose: To assess the toxicity and clinical benefit from adjuvant chemoradiotherapy consisting of protracted venous infusion 5-fluorouracil (5-FU) and concomitant radiotherapy in patients with resected pancreatic cancer. Methods and Materials: Between 1994 and 1999, 52 patients who underwent pancreaticoduodenectomy received adjuvant chemoradiotherapy. The tumor bed and regional nodes received a dose of 45 Gy in fractions of 1.8 Gy followed by boost to the tumor bed if the surgical margins were involved (total dose, 54 Gy). The patients also received concomitant 5-FU by protracted venous infusion (200-250 mg/m2/day, 7 days/week) during the entire radiotherapy course. Results: Fifty-two patients (30 men, 22 women) were enrolled and treated on this protocol. The median age was 63 years (range, 38-78 years), and the median Karnofsky Performance Status was 80 (range, 70-100). Thirty-five percent had involved surgical margins and 59% had involved lymph nodes. All patients completed therapy, and there were no Grade IV/V toxicities observed. With median follow-up of 24 months (range, 3-52 months) for surviving patients, the median survival is 32 months, and 2-year and 3-year survivals are 62%, and 39%, respectively. Conclusion: Radiotherapy with concomitant 5-FU by protracted venous infusion as adjuvant treatment for resected pancreatic cancer is well tolerated. This approach allows for greater dose intensity with reduced toxicity. The median survival of this cohort of patients compares favorably with our earlier experience and other published series.

    Background Mitral valve disease is often accompanied by concomitant tricuspid valve disease. The purpose of this study was to determine the influence of performing tricuspid procedures in the setting of mitral valve surgery within a multi-institutional patient population. Methods From 2001–2008, 5,495 mitral valve operations were performed at 17 different statewide centers. Patients underwent either mitral valve alone (MV alone, n=5,062, age=63.4±13.0 years) or mitral + tricuspid valve operations (MV+TV, n=433, age=64.0±14.2 years). Univariate and multivariate analyses were used to assess the influence of concomitant tricuspid procedures on operative mortality and the composite incidence of major complications. Results Patients undergoing MV+TV were more commonly female (62.7% vs. 45.5%, p<0.001), had higher rates of heart failure (73.7% vs. 50.9%, p<0.001), and more frequently underwent reoperations (17.1% vs. 7.4%, p<0.001) compared to MV alone patients. Other patient characteristics, including preoperative endocarditis (8.5% vs. 8.2%, p=0.78), were similar between groups. Mitral replacement (63.5%) was more common than repair (36.5%, p<0.001) in MV+TV operations, and MV+TV operations incurred longer median cardiopulmonary bypass (181 min. vs. 149 min, p<0.001) times. Unadjusted operative mortality (6.0% vs. 10.4%, p=0.001) and postoperative complications were higher following MV+TV compared to MV alone. Importantly, after risk adjustment, performance of concomitant tricuspid valve procedures proved an independent predictor of operative mortality (OR=1.50, p=0.03) and major complications (OR=1.39, p=0.004). Conclusions Concomitant tricuspid surgery is a proxy for more advanced valve disease. Compared to mitral operations alone, simultaneous mitral-tricuspid valve operations are associated with elevated morbidity and mortality even after risk adjustment. This elevated risk should be considered during preoperative patient risk stratification. PMID:22607786

    In the present work, the growth of concomitant nitride layers during a post-discharge process is studied. The analysis takes into account the similarities and differences between nitriding post-discharge processes and other nitriding processes, employing a mathematical simulation of nitrogen diffusion. The considered differences are related to the thermodynamic standard states, the nitrogen concentration on the surface and the sputtering of the surface (this one for plasma processes). Nitrogen diffusion and layer formation are described from the beginning of the process by means of a mathematical model.

    Intrauterine devices (IUDs) are rarely associated with serious infections. We report an unusual concomitant infection of group A Streptococcus (GAS) causing toxic shock syndrome and pelvic abscess with Actinomyces odontolyticus associated with an IUD in a healthy 50-year-old patient. The IUD was subsequently removed and the patient recovered on the appropriate antibiotics. This case highlights the importance of clinicians' high index of suspicion of an IUD infection and prompt removal of the infected foreign body to obtain source control. PMID:26965406

    Hydrogen bonding between urea functionalities is a common structural motif employed in crystal-engineering studies. Crystallization of 1,3-bis(3-fluorophenyl)urea, C13H10F2N2O, from many solvents yielded concomitant mixtures of at least two polymorphs. In the monoclinic form, one-dimensional chains of hydrogen-bonded urea molecules align in an antiparallel orientation, as is typical of many diphenylureas. In the orthorhombic form, one-dimensional chains of hydrogen-bonded urea molecules have a parallel orientation rarely observed in symmetrically substituted diphenylureas.

    The association of congenital tracheal stenosis and tracheoesophageal (TE) fistula is rare. Here, we report 2 patients with tracheobronchial stenosis (complete cartilage ring) involving the lower trachea and right bronchus. Both patients had associated VACTERL (vertebral anomalies, anal atresia, cardiovascular anomalies, TE, renal, and limb defects) congenital cardiac defects and tracheal diverticula after repair of the TE fistula in type C esophageal atresia. The stenotic segment began at the orifice of the TE fistula, which became diverticula after the TE fistula was repaired. Concomitant repair of congenital cardiac defects and a slide tracheoplasty with elimination of the diverticula were performed successfully. PMID:24088476

    Although antinuclear campaigns seem to be effective, public communication and education efforts on low-level radioactive waste have mixed results. Attempts at public information programs on low-level radioactive waste still focus on influencing public opinion. A question then is: {open_quotes}Is it preferable to have a program focus on public education that will empower individuals to make informed decisions rather than trying to influence them in their decisions?{close_quotes} To address this question, a case study with both quantitative and qualitative data will be used. The Ohio Low-Level Radioactive Waste Education Program has a goal to provide people with information they want/need to make their own decisions. The program initiated its efforts by conducting a statewide survey to determine information needed by people and where they turned for that information. This presentation reports data from the survey and then explores the program development process in which programs were designed and presented using the information. Pre and post data from the programs reveal attitude and knowledge shifts.

    Aim To measure the penetration of capecitabine from the plasma into tissue and to investigate the pharmacokinetics of its metabolizing into fluorouracil (5-FU) in patients with advanced breast cancer. Methods Twenty-seven patients with breast cancer received repeated doses of 1 255 mg·m-2 of capecitabine twice daily for 7 d. Blood, tumor, and adjacent healthy tissue samples were collected. The concentrations of capecitabine and its metabolite 5-FU were determined by HPLC. The concentration-time profiles of capecitabine and 5-FU were fitted by pharmacokinetic model. The tissue distribution factors for capecitabine and 5-FU, and the AUC ratios of 5-FU to capecitabine in plasma, tumor or adjacent healthy tissue, were calculated with pharmacokinetic parameters, respectively. Results The Ka of capecitabine was 1.17 h-1 in plasma, 0.46 h-1 in tumor tissue, and 0.61 h-1 in healthy tissue. The AUCs of capecitabine were 2.557 1 μg·mL-1·h, 1.629 2 μg·g-1·h and 2.085 0 μg·g-1·h, and T1/2 was 0.782 3 h, 1.528 1 h and 1.289 6 h in plasma, tumor, and healthy tissue, respectively. The AUCs of 5-FU were 0.418 7 μg·mL-1 h, 1.671 7 μg·g-1·h and 1.020 8 μg·g-1·h; the T1/2 was 0.631 3 h ,1.204 1 h and 1.031 2 h in plasma, tumor, and healthy tissue, respectively. The tissue distribution factors of capecitabine were 0.637 1 in tumor (AUCcap-Tumor/AUCcap-plasma) and 0.851 4 in healthy tissue (AUCcap-HT/AUCcap-plasma). The tissue distribution factors of 5-FU were 3.992 6 in tumor (AUC5-FU-tumor/AUC5-FU-plasma) and 2.438 0 in healthy tissue (AUC5-FU-HT/AUC5-FU-plasma). The AUC ratios of 5-FU to capecitabine were 0.1637, 1.0261, and 0.489 5 in plasma, tumor, and healthy tissue, respectively. Conclusion The simulation curves for the disposition of capecitabine and its metabolite 5-FU in plasma and tissue basically describe the activation process of capecitabine metabolizing to 5-FU and 5-FU elimination. There are similar distributions for capecitabine in plasma, tumor, and

    Combined orthognathic and total joint reconstruction cases can be predictably performed in 1 stage. Use of virtual surgical planning can eliminate a significant time requirement in preparation of concomitant orthognathic and temporomandibular joint (TMJ) prostheses cases. The concomitant TMJ and orthognathic surgery-computer-assisted surgical simulation technique increases the accuracy of combined cases. In order to have flexibility in positioning of the total joint prosthesis, recontouring of the lateral aspect of the rami is advantageous.

    The authors report a retrospective study which aimed at assessing the use of a concomitant chemo-radiotherapy, its tolerance and its feasibility in the case of a locally advanced rectum cancer. Based on data obtained among 62 patients presenting a rectum cancer, they analyse the results in terms of tolerance (cases of leukopenia, anemia, diarrhea, radiodermatitis), of relapses, and survival. Toxicity is acceptable and the concomitant treatment renders the tumour operable in many cases. Short communication

  1. Comparison of three concomitant boost techniques for early-stage breast cancer

    International Nuclear Information System (INIS)

    Purpose: Whole breast radiotherapy (RT) followed by a tumor bed boost typically spans 5-6 weeks of treatment. Interest is growing in RT regimens, such as concomitant boost, that decrease overall treatment time, lessening the time/cost burden to patients and facilities. Methods and Materials: Computed tomography (CT) scans from 20 cases were selected for this retrospective, dosimetric study to compare three different techniques of concomitant boost delivery: (1) standard tangents plus an electron boost (2) intensity-modulated RT (IMRT) tangents using custom compensators plus an electron boost, and (3) IMRT tangents plus a conformal photon boost. The equivalent uniform dose model was used to compare the plans. Results: The average breast equivalent uniform dose value for the three techniques (standard, IMRT plus electrons, and IMRT plus photons) was 48.6, 47.9, and 48.3, respectively. The plans using IMRT more closely approximated the prescribed dose of 46 Gy to the whole breast. The breast volume receiving >110% of the dose was less with the IMRT tangents than with standard RT (p 0.037), but no significant difference in the maximal dose or other evaluated parameters was noted. Conclusion: Although the IMRT techniques delivered the prescribed dose with better dose uniformity, the small improvement seen did not support a goal of improved resource use

  2. Whole-body MR vascular screening detects unsuspected concomitant vascular disease in coronary heart disease patients

    International Nuclear Information System (INIS)

    Coronary heart disease (CHD) patients often show atherosclerotic vascular disease in other vascular territories. We evaluated how often whole-body MR imaging detects concomitant arterial pathologies in CHD patients, and how often these pathologies were not known to the patients previously. Of 4,814 participants in the population-based Heinz Nixdorf Recall Study, 327 reported CHD (i.e., previous coronary bypass surgery, angioplasty); of those, 160 patients (mean age 66.4 years) were examined using MR of the brain, the heart (excluding the coronary arteries), and whole-body MR angiography. The prevalence of each vascular pathology was assessed, correlated to the others and compared to patients' histories. Of the 160 CHD patients, 16 (10%) showed MR signs of stroke, and 77 (48.1%) had a stenosis >50% in at least one extracerebral peripheral artery (other than the coronaries), including 28 (17.5%) with relevant renal artery stenoses, and 20 (12.5%) with relevant extracerebral internal carotid artery stenoses. False negative histories were reported in 12 of 81 cases with myocardial infarctions, and in 11 of 16 cases with cerebrovascular infarctions. This whole-body atherosclerosis MR screening program allows previously unknown concomitant vascular disease to be detected in coronary heart disease patients. Its prospective value should be assessed in further studies. (orig.)

  4. Superselective arterial infusion and concomitant radiotherapy for advanced head and neck cancer

    International Nuclear Information System (INIS)

    Superselective arterial infusion for patients with advanced head and neck cancer has increasingly been applied in Japan. We analyzed our experiences and evaluated the efficacy and safety of this treatment. Forty-four patients, who were considered contraindicated for surgery or rejected radical surgery, received superselective intra-arterial infusion therapy of cisplatin (100-120 mg/m2/week) with simultaneous intravenous infusion of thiosulfate to neutralize cisplatin toxicity, and conventional concomitant extrabeam radiotherapy (65 Gy/26 f/6.5 weeks). During the median follow-up period of 17 months, 2-year progression-free survival rate of primary lesion was 66.9%, and that of patients with T4b diseases 57%. The 2-year overall survival rate was 52.4%. Although acute toxic effects were considered acceptable, severe toxic events occurred in some cases, namely, cranial nerve palsy, Methicillin-resistant Staphylococcus aureus (MRSA) pneumonia, sepsis, and osteoradionecrosis. We confirmed the high effectiveness of superselective arterial infusion and concomitant radiotherapy, which can concentrate the attack of decadose cisplatin on locoregional disease. Moreover, even patients with unresectable disease can be cured. We must clarify the treatment results and late side effects, and establish the indications for this treatment. (author)

    Full Text Available Aim: The aim of this study was to determine the pattern of midface trauma with associated concomitant injuries seen in our environment. Methodology: This was a prospective analysis of trauma patients with midfacial injuries presenting at a referral center in South West Nigeria. In addition to socio-demographic data, the following information was also obtained: Mechanism of injuries, type of midfacial injuries, concomitant/associated injuries and treatment. Results: A total of 101 patients with midfacial injuries were involved. They were made up of 85 males and 16 females. The 20-29 year age group was mostly affected (44.6% and the most common cause of midface injuries was road traffic accident (91.1%. The zygoma was fractured more than any other midfacial bone (46.0%. A total of 144 associated injuries were recorded among these patients, head and ocular injuries accounted for 49 (34% and 35 (24.3% respectively. The patients were mostly treated conservatively or by closed reduction. Conclusion: The rate of head and ocular injuries among patients with midfacial injury was high. Knowledge of these associated injuries provides useful strategies for patient care and prevention of further complications. A multidisciplinary approach is important for optimum management of these patients.

To report on the use and feasibility of a multimodality approach using concomitant radiotherapy and chemotherapy in patients with high-risk nonmelanoma skin carcinoma (NMSC of the head and neck. Methods. Records of patients with NMSC of the head and neck who received concomitant CRT at the University of North Carolina between 2001 and 2007 were reviewed. Results. Fifteen identified patients had at least one of the following high-risk factors: T4 disease (93%, unresectability (60%, regional nodal involvement (40%, and/or recurrence (47%. Ten patients were treated in the definitive setting and five in the postoperative setting. Platinum based chemotherapy was given in 14 (93% patients. Ten of fifteen (67% patients completed all planned chemotherapy treatments, and thirteen patients (87% completed at least 80% of planned chemotherapy. Mild radiation dermatitis occurred in all patients and reached grade 3 in 13% of patients. No patients experienced grade 4 or 5 toxicity. With a median followup of 31 months in surviving patients, the 2-year actuarial locoregional control and relapse-free survival were 79% and 49%, respectively. Conclusions. Definitive or postoperative chemoradiotherapy for patients with locally advanced or regionally metastasized NMSC of the head and neck appears feasible with acceptable toxicities and favorable locoregional control.

    The efficiency of two white-rot fungi (WRF), Trametes versicolor and Ganoderma lucidum, to eliminate thirteen pharmaceutical pollutants with concomitant biodiesel production from the accumulating lipid content after treatment, was examined. The removal efficiency was studied using both individual and combined strains. The results of individual and combined strains showed a total removal (100%) of diclofenac (DCF), gemfibrozil (GFZ), ibuprofen (IBP), progesterone (PGT) and ranitidine (RNT). Lower removals were achieved for 4-acetamidoantipyrin (AAA), clofibric acid (ACF), atenolol (ATN), caffeine (CFN), carbamazepine (CZP), hydrochlorothiazide (HCT), sulfamethoxazole (SMX) and sulpiride (SPD), although the combination of both strains enhanced the system's efficiency, with removals ranging from 15 to 41%. This increase of the removal efficiency when combining both strains was attributed to the interactions developed between them (i.e., competition). Results from enzymatic and cytochrome P450 examination suggested that both extracellular (laccase, MnP, LiP) and intracellular oxidation mechanisms participate in the biological removal of pharmaceuticals. On the other hand, the "green" potential of the fungal sludge generated during the biological removal process was assessed for biodiesel production by means of one-step direct (in-situ) transformation. This process consists of the simultaneous extraction and conversion of lipids contained in the sludge by catalytic esterification/transesterification using a robust acid heterogeneous Zr-SBA-15 catalyst. This catalytic system provided conversions close to 80% of the saponifiable fraction (including free fatty acids and glycerides) in the presence of high amount of impurities. The overall weight FAME yield, based on the initial dried mass, was close to 30% for both strains. PMID:27233048

    Background: Rodent models for urban air pollution show consistent induction of inflammatory responses in major brain regions. However, the initial impact of air pollution particulate material on olfactory gateways has not been reported. Objective: We evaluated the olfactory neuroepithelium (OE) and brain regional responses to a nanosized subfraction of urban traffic ultrafine particulate matter (nPM, < 200 nm) in vivo, ex vivo, and in vitro. Methods: Adult mice were exposed to reaerosolized nPM for 5, 20, and 45 cumulative hours over 3 weeks. The OE, the olfactory bulb (OB), the cerebral cortex, and the cerebellum were analyzed for oxidative stress and inflammatory responses. Acute responses of the OE to liquid nPM suspensions were studied with ex vivo and primary OE cultures. Results: After exposure to nPM, the OE and OB had rapid increases of 4-hydroxy-2-nonenal (4-HNE) and 3-nitrotyrosine (3-NT) protein adducts, whereas the cerebral cortex and cerebellum did not respond at any time. All brain regions showed increased levels of tumor necrosis factor-α (TNFα) protein by 45 hr, with earlier induction of TNFα mRNA in OE and OB. These responses corresponded to in vitro OE and mixed glial responses, with rapid induction of nitrite and inducible nitric oxide synthase (iNOS), followed by induction of TNFα. Conclusions: These findings show the differential time course of oxidative stress and inflammatory responses to nPM between the OE and the brain. Slow cumulative transport of inhaled nPM into the brain may contribute to delayed responses of proximal and distal brain regions, with potential input from systemic factors.

    2016-01-01

    Full Text Available Background: The current standard recommendation is to avoid surgical interventions in patients taking oral isotretinoin. However, this recommendation has been questioned in several recent publications. Aim: To document the safety of cosmetic and surgical interventions, among patients receiving or recently received oral isotretinoin. Materials and Methods: Association of Cutaneous Surgeons, India, in May 2012, initiated this study, at 11 centers in different parts of India. The data of 183 cases were collected monthly, from June 2012 to May 2013. Of these 61 patients had stopped oral isotretinoin before surgery and 122 were concomitantly taking oral isotretinoin during the study period. In these 183 patients, a total of 504 interventions were performed. These included[1] 246 sessions of chemical peels such as glycolic acid, salicylic acid, trichloroacetic acid, and combination peels;[2] 158 sessions of lasers such as ablative fractional laser resurfacing with erbium-doped yttrium aluminum garnet and CO2, conventional full face CO2laser resurfacing, laser-assisted hair reduction with long-pulsed neodymium-doped yttrium aluminum garnet, diode laser, and LASIK surgery;[3] 27 sessions of cold steel surgeries such as microneedling, skin biopsy, subcision, punch elevation of scars, excision of skin lesion, and wisdom tooth extraction;[4] 1 session of electrosurgery. Results: No significant side effects were noted in most patients. 2 cases of keloid were documented which amounted to 0.4% of side effects in 504 interventions, with a significant P value of 0.000. Reversible transient side effects were erythema in 10 interventions and hyperpigmentation in 15. Conclusion: The study showed that performing dermatosurgical and laser procedures in patients receiving or recently received isotretinoin is safe, and the current guidelines of avoiding dermatosurgical and laser interventions in such patients taking isotretinoin need to be revised.

    Objective:To compare the differences of cellular immunological functional changes and survival time of chemotherapy concomitant with multiple autologous immunocytes with single chemotherapy on patients with colorectal carcinoma (CRC). Methods: Of the 83 CRC patients, 43 were treated with single chemotherapy (single chemotherapy group) while the other 40 were given chemotherapy concomitant with multiple autologous immunocytes (combined chemotherapy group). Blood cell separator was applied to collect autologous peripheral blood mononuclear (PBMC) which was used to induce the cultures of peripheral blood CD3AK cell, CIK cell, dendritic cell (DC), γδT cell and NK cell based on routine approaches. Peripheral blood CD3+, CD4+, CD8+, CD19+, CD16+, CD56+, CD4/CD8 andγδT cell ratio as well as the positive expression rates of perforin, granular enzyme B and CD107a in PBMC were determined by lfow cytometer. Same chemotherapy (oxaliplatin + CF + 5-FU) was intravenously given to both groups, while in combination group, 4, 6, 9, 11 and 10 patients received 3, 6, 7, 10 and>16 courses of treatment, respectively. Results:Subgroup of immunocytes and absolute value in combined chemotherapy group were evidently higher than in single chemotherapy group, but there was no significant difference in Karnofsky score. In addition, combined chemotherapy group was apparently higher after treatment than treatment before and single chemotherapy group in the results of perforin, granular enzyme B (GranB) and CD107a in PBMC. Additionally, 1-, 2- and 5-year survival rates in combined chemotherapy group (in phases Ⅱ, Ⅲand Ⅳ) were 70.0%(28/40), 20.0%(8/40) and 10.0%(4/40), higher than those in single chemotherapy group [23.2% (10/43), 7.0% (3/43) and 4.6%(2/43)], respectively, in which the differences in phases Ⅱand Ⅲwere more signiifcant (P Conclusion:Chemotherapy concomitant with multiple autologous immunocytes can improve the immunological function and prolong survival time for

    Extraintestinal manifestations (EIMs) cause increased morbidity and decreased quality of life in Crohn disease (CD). Ankylosing spondylitis (AS) belongs to EIMs. Very little is known on the clinical features of CD concomitant with AS. This study is to investigate the clinical features of CD patients with AS.We retrospectively collected all CD patients with AS in our hospital, and established a comparison group (CD without AS) with age, sex, and duration of Crohn disease matched. Clinical information was retrieved for comparison.Eight CD + AS patients were identified from 195 CD patients. Sixteen CD patients were randomly selected into comparison group. All CD + AS patients were male, HLA-B27 (+), and rheumatoid factor (-) with an average age of 40.8 ± 4.52 years. Significant correlation between disease activity of CD and AS was revealed (r = 0.857, P = 0.011). Significant correlation between disease activity of CD and functional limitation associated with AS was identified (r = 0.881, P < 0.01). C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), and globulin were positively correlated to Crohn disease activity index (CDAI), Bath AS disease activity index, and Bath AS functional index(BASFI) scores (r = 0.73-0.93, P < 0.05). Albumin was negatively associated with CDAI and BASFI (r = -0.73 to -0.91, P < 0.05). The ratio of albumin to globulin (Alb/Glo) was significantly related to all 3 scores (r = -0.81 to -0.91, P < 0.05).Male predominance with a 4.12% concomitant incidence of AS is observed in CD patients. Disease activity of CD correlates with disease activity of AS and functional limitation caused by AS. CRP, ESR, and Alb/Glo may serve as biomarkers for disease activity and functional limitation in CD patients concomitant with AS, although future studies are expected. PMID:27428240

    Full Text Available BACKGROUND: Herb-drug interactions are an important issue in drug safety and clinical practice. The aim of this epidemiological study was to characterize associations of clinical outcomes with concomitant herbal and antipsychotic use in patients with schizophrenia. METHODS AND FINDINGS: In this retrospective, cross-sectional study, 1795 patients with schizophrenia who were randomly selected from 17 psychiatric hospitals in China were interviewed face-to-face using a structured questionnaire. Association analyses were conducted to examine correlates between Chinese medicine (CM use and demographic, clinical variables, antipsychotic medication mode, and clinical outcomes. The prevalence of concomitant CM and antipsychotic treatment was 36.4% [95% confidence interval (95% CI 34.2%-38.6%]. Patients using concomitant CM had a significantly greater chance of improved outcomes than non-CM use (61.1% vs. 34.3%, OR = 3.44, 95% CI 2.80-4.24. However, a small but significant number of patients treated concomitantly with CM had a greater risk of developing worse outcomes (7.2% vs. 4.4%, OR = 2.06, 95% CI 2.06-4.83. Significant predictors for concomitant CM treatment-associated outcomes were residence in urban areas, paranoid psychosis, and exceeding 3 months of CM use. Herbal medicine regimens containing Radix Bupleuri, Fructus Gardenia, Fructus Schisandrae, Radix Rehmanniae, Akebia Caulis, and Semen Plantaginis in concomitant use with quetiapine, clozapine, and olanzepine were associated with nearly 60% of the risk of adverse outcomes. CONCLUSIONS: Concomitant herbal and antipsychotic treatment could produce either beneficial or adverse clinical effects in schizophrenic population. Potential herb-drug pharmacokinetic interactions need to be further evaluated.

  19. Surface contamination initiated laser damage

    International Nuclear Information System (INIS)

    We are engaged in a comprehensive effort to understand and model the initiation and growth of laser damage initiated by surface contaminants. This includes, for example, the initial absorption by the contaminant, heating and plasma generation, pressure and thermal loading of the transparent substrate, and subsequent shockwave propagation, ''splashing'' of molten material and possible spallation, optical propagation and scattering, and treatment of material fracture. The integration use of large radiation hydrodynamics codes, optical propagation codes and material strength codes enables a comprehensive view of the damage process The following picture of surface contaminant initiated laser damage is emerging from our simulations. On the entrance optical surface, small particles can ablate nearly completely. In this case, only relatively weak shockwaves are launched into the substrate, but some particulate material may be left on the surface to act as a diffraction mask and cause further absorption. Diffraction by wavelength scale scattering centers can lead to significant intensity modulation. Larger particles will not be completely vaporized. The shockwave generated in this case 1642is larger and can lead to spallation of contaminant material which then may be deposited in the substrate. A gaseous atmosphere can lead to radiation trapping with concomitant increases in temperature and pressure near the surface. In addition, supersonic ionization waves in air may be generated which greatly extend the plasma plume spatially and temporally. Contaminants on the exit optical surface behave differently. They tend to heat and pop off completely in which case significant damage may not occur. Since plasma formed at the interface of the optic and absorbing particle is confined, much stronger pressures are generated in this case. Imaging of contaminants resulting in ''writing'' a diffraction pattern on the exit surface due to contamination on the entrance surface has been

    Turner syndrome (TS) is a genetic disorder that affects development in females and is characterized by the complete or partial absence of the second sex chromosome, or monosomy X. TS is associated with abnormalities in lymphatic and skeletal development, in growth, and in gonadal function. Cardiac and renal malformations and a number of specific cognitive findings may also be encountered in these patients. An increased risk for hypothyroidism, sensorineural hearing loss, hypertension, and other problems has also been reported. We present the case of a patient with TS accompanied by transient hypogammaglobulinaemia of infancy (THI) and central diabetes insipidus, which we believe is the first reported TS patient with these concomitant disorders. Conflict of interest:None declared. PMID:23419422

    2014-01-01

    Full Text Available A 13-year-old patient with a complaint of worsening lower abdominal pain during the past 4 months was admitted to the emergency department. An abdominopelvic ultrasound scan revealed a distended uterocervical cavity suggestive of hematometrocolpos. Imperforate hymen was observed on examination of the external genitalia. MRI scan revealed an air-fluid level representing pyometrocolpos within a distended vagina. Posterior vaginal extraperitoneal leakage as the sign of a fistula between the vagina and the rectovaginal space was detected. Although laparoscopic approach was planned, malodorous pus expelled after the insertion of the Veress needle, it was decided to proceed to laparotomy. Pus with peritoneal microabscess formations was observed at laparotomy. The imperforate hymen and TVS were excised vaginally. A more complex anomaly should be suspected in cases with hematometra and concomitant imperforated hymen without any bulging and thorough evaluation using radiological imaging techniques should be performed before surgical approach.

    Full Text Available Cyclophosphamide is an immunosuppressive agent and an anticancer prodrug which requires bioactivation catalyzed primarily by cytochrome P450 enzymes in order to be transformed into its active alkylating compounds. Concomitant administration of drugs known to inhibit or induce this enzyme system is a clinical concern. Herein, we present the case of a chronically ill 21-year-old patient who received high-dose cyclophosphamide, equine antithymocyte globulin (eATG, and total body irradiation (TBI followed by an allogeneic hematopoietic stem cell transplant (HSCT for severe aplastic anemia. Throughout her hospitalization, she continued to receive quadruple anticonvulsant therapy including phenobarbital for her long-standing seizure history. The preparative regimen was tolerated well aside from a hypersensitivity reaction to eATG, and minimal cyclophosphamide-related toxicities. Safe and effective administration of high-dose cyclophosphamide was possible with multidisciplinary care consisting of physician, nursing, pharmacy, neurology consultation, as well as social work and case management.

    So far, standard therapy of complex thoracoabdominal aortic disease is open surgical repair requiring aortic clamping and replacement of the involved segment.Despite significant improvements, morbidity and mortality of open surgery remain high.I As a result, open surgery is often withheld owing to severe comorbidities of the patients. Endovascular technique has emerged as an alternative for treatment of these diseases in high risk patients,2 and has enlarged the options of treatment of complex aortic diseases. However, an endovascular approach alone is often deemed unsuitable for some complex aortic disorders because of the close proximity of the supraaortic or visceral branches. A hybrid open-endovascular approach has therefore been proposed as a viable alternative. We present here a unique patient with recurring thoracoabdominal aortic aneurysm (TAAA) concomitant with an aortic dissection (AD) treated by a hybrid open-endovascular approach.

    Twenty-nine bacterial isolates representing eight genera from the gastrointestinal tracts of feral brook trout Salvelinus fontinalis (Mitchell) demonstrated multiple maximal antibiotic resistances and concomitant broad-spectrum mercury (Hg) resistance. Equivalent viable plate counts on tryptic soy agar supplemented with either 0 or 25 μM HgCl2 verified the ubiquity of mercury resistance in this microbial environment. Mercury levels in lake water samples measured 1.5 ng L−1; mercury concentrations in fish filets ranged from 81.8 to 1,080 ng g−1 and correlated with fish length. The presence of similar antibiotic and Hg resistance patterns in multiple genera of gastrointestinal microflora supports a growing body of research that multiple selective genes can be transferred horizontally in the presence of an unrelated individual selective pressure. We present data that bioaccumulation of non-point source Hg pollution could be a selective pressure to accumulate both antibiotic and Hg resistant bacteria. PMID:22850694

    A 9-year-old boy with congenital atresia of the left main coronary artery underwent myocardial revascularization. Coarctation of the aorta and ventricular septal defect were diagnosed at the age of 1 year. At age 7 years, the child presented with syncope while exercising. Preoperative evaluation included cardiac catheterization which revealed the unexpected finding of congenital atresia of the left main coronary artery with origin of the circumflex artery from the right coronary artery. Surgical correction included myocardial revascularization by means of left internal mammary artery graft to the anterior descending coronary artery, coarctation resection, and ventricular septal defect repair. The patient recovered uneventfully. We report the details of this extremely rare case with successful concomitant surgical management of the congenital coronary artery anomaly and the associated structural heart disease. PMID:23804483

    The complexity of caring for the ageing heart failure (HF) population is further complicated by concomitant chronic conditions (i.e., polypharmacy, depression), age related impairments (i.e., hearing, visual and cognitive impairments, impairments in activities of daily living (ADL/IADL), and other issues (e.g., health illiteracy, lack of social support). This paper provides an overview of these risk factors, outlines how they individually and in interplay endanger favourable outcome by putting patients at risk for poor self-management. Moreover, suggestions are made on how these issues could be addressed and integrated in heart failure management by applying gerontological care principles in caring for the ageing heart failure population.

    Full Text Available Dens evaginatus also referred to as a talon's cusp, is a developmental anomalycharacterized by formation of a well - delineated additional cusp that extends from thecementoenamel junction to the incisal edge. Dens invaginatus is a developmentalanomaly caused by invagination of the surface of the tooth crown before calcificationhas occurred. Dens evaginatus and dens invaginatus are usually present in isolationand many cases have been reported. But, their concomitance is highly rare and unusualand requires documentation. A case report of a 9 year old child with a combination ofthe talon cusp and dens invagination in the right maxillary lateral incisor is presentedhere. Such a tooth due to its unusual morphology is susceptible to food lodgmentleading to carious invasion. Hence early diagnosis and prophylactic therapy isimportant.

    Full Text Available The association of elbow dislocation with fracture of the lateral condyle in paediatrics is considered very rare and only a few isolated cases have been reported in the literature. Due to its rarity, some of the authors have classified this injury as a complex elbow injury and have deemed them technically demanding to repair. A ten-year-old boy presented to us with a lateral condyle humerus fracture [Milch type 2] with concomitant postero-medial elbow dislocation following a fall on his outstretched hand. At 34 months of follow-up, the child regained a full range of motions around the elbow joint without any deformities.This combination injury, although rare, is not technically different or difficult to treat.

    @@ Introduction Neuroendocrine tumor covers a wide range of neoplasms that originate in the neuroendocrine cells which spread throughout the body.Carcinoid tumor, and neuroendocrine tumor are low-grade malignant tumors, their growth is slow, and mainly in the gastrointestinal epithelium. Esophageal adenocarcinoma tumor is a big problem in esophageal cancer. Combined esophageal adenocarcinoma and carcinoid tumor both as primary tumors is very rare[1]. Neuroendocrine tumors of the esophagus are derived from the diffuse neuroendocrine system in the gastrointestinal tract. Neuroendocrine tumors in the esophagus can be distinguished from other mesenchymal tumors by immunostaining for synaptophysin and chromogranin-A. Both carcinoid of the esophagus and adenocarcinoma of the esophagus are malignant tumors and considered to have a specifi c molecular pathogenesis. This paper presents a rare case diagnosed as carcinoid of the esophagus concomitant with an adenocarcinoma of the esophagus, a review of the literature is also presented here.

    Full Text Available OBJECTIVES: Information on the prevalence and concomitants of arthritis in developing countries is sparse. It is unclear whether they are comparable to findings in developed countries. To ascertain the prevalence, demographic characteristics, and health-related concomitants of arthritis in older persons in the southern state of Rio Grande do Sul, Brazil, a middle income country. METHODS: The state of Rio Grande do Sul, Brazil, was subdivided into nine regions. Stratified random sampling was used to identify 880 community residents age ≥60 years in each region. One region with suspect data was excluded. Of 7040 community residents contacted in eight regions, 6963 participated (1.1% refusal rate. In 1995, trained, monitored interviewers, using structured questionnaires, conducted in-home interviews gathering information on demographic characteristics (age, sex, race/ethnicity, education, income, living arrangements, employment status, health behaviors (physical activity, tobacco use, social activity, functional limitations, depression, and 15 self-reported health conditions, including arthritis. Data were analyzed using descriptive statistics and logistic regression. RESULTS: Arthritis, reported by 43% of the sample, was more prevalent in women, among the less educated, those with lower income, and higher age. Severity, but not prevalence, differed by race/ethnicity. Controlled analyses indicated significant association with female gender, lower education, and less social activity. Arthritis was associated with reduced odds of stroke, but increased odds of hypertension, varicosities, bronchitis, renal problems, headache, gastrointestinal disorders, and depression. Arthritis was not significantly associated with age or functional limitations, and associations did not differ by gender. CONCLUSIONS: The prevalence, demographic and health characteristics associated with self-reported arthritis in this southern state in Brazil are similar to findings

    Full Text Available Aim: Head and neck cancer is one of the most commonly occurring malignancies in the world. In India, the most commonly occurring head and neck cancers are those of the oral cavity and the pharynx. The majority of these cancers present with stage III/IV disease. Surgery and radiation therapy are the main treatment modalities. Concomitant chemoradiation is being investigated with the goal of improved local control that translates into improved survival. In this background, we have started this prospective randomized trial to ascertain the dose, schedule and sequence of therapy and to note whether Vinorelbine as radiosensitizer is equally effective as Cisplatin, comparing compliance, local control and toxicity. Patients and Methods: Forty patients of advanced head and neck cancer were randomized into two arms. Arm A received weekly injection Cisplatin 40mg/m 2 along with radiation. Arm B received weekly injection of Vinorelbine 6mg/m 2 along with radiation. Radiotherapy was delivered at a dose of 6,600-7,000 Gy in conventional fractionation in a telecobalt machine. Results: The complete response (CR rate was higher in arm B (90% than in arm A (70%. Major toxicities included neutropenia, anemia, mucositis and nausea. Conclusion: Concomitant chemoradiation with Vinorelbine produced more CR than chemoradiation with Cisplatin in advanced head and neck cancer. Toxicities were more in the Cisplatin arm, but they were manageable. Although a majority of the study was performed using Cisplatin as the radiosensitizer, Vinorelbine can be recommended as radiosensitizer in advanced head and neck malignancy.

    Full Text Available Abstract Background Cataract and glaucoma are both common comorbidities among older patients. Combining glaucoma surgery with minimal invasive phacoemulsification (phaco is a considerable option to treat both conditions at the same time, although the combination with filtration surgery can produce a strong inflammatory response. Combined non-penetrating procedures like canaloplasty have shown to reduce intraocular pressure (IOP comparable to trabeculectomy without the risk of serious bleb-related complications. The purpose of this retrospective study was to compare the outcomes of phacotrabeculectomy and phacocanaloplasty. Methods Thirty-nine eyes with concomitant cataract and glaucoma who underwent phacotrabeculectomy (n = 20; 51.3% or phacocanaloplasty (n = 19; 48.7% were included into this trial on reduction of IOP, use of medication, success rate, incidence of complications and postsurgical interventions. Complete success was defined as IOP reduction by 30% or more and to 21 mmHg or less (definition 1a or IOP to less than 18 mmHg (definition 2a without glaucoma medication. Results Over a 12-month follow-up, baseline IOP significantly decreased from 30.0 ± 5.3 mmHg with a mean of 2.5 ± 1.2 glaucoma medications to 11.7 ± 3.5 mmHg with a mean of 0.2 ± 0.4 medications in eyes with phacotrabeculectomy (P  Conclusions Phacocanaloplasty offers a new alternative to phacotrabeculectomy for treatment of concomitant glaucoma and cataract, although phacotrabeculectomy yielded in better results in terms of IOP maintained without glaucoma medications.

  16. Bilateral posterior RION after concomitant radiochemotherapy with temozolomide in a patient with glioblastoma multiforme: a case report

    International Nuclear Information System (INIS)

    Radiation induced optic neuropathy (RION) is a rare but severe consequence of radiation therapy that is associated with adjuvant chemotherapy, specifically therapy with vincristine or nitrosoureas. However, there is very little evidence regarding the occurrence of RION after concomitant radiochemotherapy with temozolomide. The case of a 63 year old woman with glioblastoma multiforme and concomitant radiochemotherapy with temozolomide is described. Due to a slight depressive episode the patient also took hypericum perforatum. Five months after cessation of fractionated radiation and adjuvant chemotherapy with temozolomide (cumulative dose of 11040 mg) the patient developed bilateral amaurosis due to RION. Tumor regrowth was excluded by magnetic resonance imaging. After the application of gadolinium a pathognomonic contrast enhancement of both prechiasmatic optic nerves could be observed. In this patient, the occurrence of RION may have been the result of radiosensitization by temozolomide, which could have been strengthened by hypericin. Consequently, physicians should avoid a concomitant application of hypericum perforatum and radiochemotherapy

    The association of primary sclerosing cholangitis (PSC) and autoimmune hepatitis (AIH) is known as an overlap syndrome (OS). OS can also be described in the setting of concomitant presence of AIH and PSC. These diseases can in some cases be associated with ulcerative colitis. In this case report we describe, to our knowledge, the first case in the literature of a young Caucasian male suffering from ulcerative colitis and an overlap syndrome consisting of an association between PSC-AIH, with the concomitant presence of a membranous glomerulonephritis.

We report a non-small cell lung cancer (NSCLC) patient with concomitant ALK rearrangement and exon 19 (E746-A750del) EGFR mutation. The ALK rearrangement was confirmed not only in the primary tumor biopsy specimen, but also in the pleural effusion cell block by reverse transcriptase-polymerase chain reaction (RT-PCR), Ventana ALK immunohistochemistry assay, and fluorescence in situ hybridization. No clinical benefit using chemotherapy or EGFR tyrosine kinase inhibitor gefitinib was obtained in this case.

  19. Hypofractionated Concomitant Intensity-Modulated Radiotherapy Boost for High-Risk Prostate Cancer: Late Toxicity

    International Nuclear Information System (INIS)

    Purpose: To report the acute and late toxicities of patients with high-risk localized prostate cancer treated using a concomitant hypofractionated, intensity-modulated radiotherapy boost combined with long-term androgen deprivation therapy. Methods and Materials: A prospective Phase I-II study of patients with any of the following: clinical Stage T3 disease, prostate-specific antigen level ≥20 ng/mL, or Gleason score 8–10. A dose of 45 Gy (1.8 Gy/fraction) was delivered to the pelvic lymph nodes with a concomitant 22.5 Gy prostate intensity-modulated radiotherapy boost, to a total of 67.5 Gy (2.7 Gy/fraction) in 25 fractions within 5 weeks. Image guidance was performed using three gold seed fiducials. The National Cancer Institute Common Terminology Criteria for Adverse Events, version 3.0, and Radiation Therapy Oncology Group late morbidity scores were used to assess the acute and late toxicities, respectively. Biochemical failure was determined using the Phoenix definition. Results: A total of 97 patients were treated and followed up for a median of 39 months, with 88% having a minimum of 24 months of follow-up. The maximal toxicity scores were recorded. The grade of acute gastrointestinal toxicity was Grade 0 in 4%, 1 in 59%, and 2 in 37%. The grade of acute urinary toxicity was Grade 0 in 8%, 1 in 50%, 2 in 39%, and 3 in 4%. The grade of late gastrointestinal toxicity was Grade 0 in 54%, 1 in 40%, and 2 in 7%. No Grade 3 or greater late gastrointestinal toxicities developed. The grade of late urinary toxicity was Grade 0 in 82%, 1 in 9%, 2 in 5%, 3 in 3%, and 4 in 1% (1 patient). All severe toxicities (Grade 3 or greater) had resolved at the last follow-up visit. The 4-year biochemical disease-free survival rate was 90.5%. Conclusions: A hypofractionated intensity-modulated radiotherapy boost delivering 67.5 Gy in 25 fractions within 5 weeks combined with pelvic nodal radiotherapy and long-term androgen deprivation therapy was well tolerated, with low rates

    Between February 1988 and December 1989, 65 patients with supraglottic cancer completed a course of concomitant boost radiotherapy. Cases with N3 disease, a Karnovsky performance score less than 70, age above 70 years, or a second primary cancer were not eligible for the study. Distribution of the patients was: Stage T1-T2 30%, T3-T4 70%, N0 68%, N+32%. The total dose ranged from 60 Gy to 76 Gy (median 66 Gy); overall treatment time ranged from 36 to 56 days with a median of 42 days. The daily dose during the first 4 weeks was 1.8 Gy, and during the last 2 weeks it was 1.6 Gy b.i.d. with a 4- or (after September 1988) 6-h interval. The clinical impression was that the early mucosal reactions were acceptable but more severe than after conventional treatment, with confluent membranous mucosal reaction being observed in 54% of the patients. Also, this reaction was significantly more frequent in patients treated with a 4-h interval (68%) than with a 6-h interval (41%) between the daily fractions. To relieve severe dysphagia, narcotics were required in 22% of the patients. The follow-up time ranged from 22 to 50 months, median 34 months. Treatment-requiring late complications were observed in 8 patients, and the 3-year actuarial risk was 17% with 95% confidence limits (6%, 27%). Two of these patients had severe complications: One of them required a temporary tracheostomy due to arytenoid edema and the other developed a laryngo-cutaneous fistula which healed after pharmacological treatment. Actuarial 3-year local-regional control was 59% (46%, 71%) and 3-year actuarial crude survival 55% (42%, 67%). There was no significant difference in the incidence of late complications or tumor control between the two groups of patients treated with a 4- or 6-h interval between the daily fractions. This study shows that the concomitant boost regimen tired here is feasible, but also stresses that the interval between dose fractions should be 6 h or more. (orig.).

Medications known to interact with diclofenac were disallowed in a clinical trial of DSG for knee OA; however, patients were not to be discontinued for intake of disallowed treatment, unless there was a safety issue. This post hoc analysis examined the frequency and type of AEs in patients who received DSG concomitantly with drugs known to have potential interactions with diclofenac. Materials and methods: This was a post hoc analysis of a randomized controlled trial of DSG for knee OA pain. Patients (n = 254 aged ≥ 35 years with OA in one or both knees, but with clinical OA symptoms in only one knee, administered DSG topically to the target knee four times daily (total dose, 16 g/d for 12 weeks. Drugs with the potential for major or moderate drug–drug interactions (DDIs were identified via Drugs.com. AE rates were compared in patients with versus those without ≥1 potential DDI. Results: At least one AE was experienced by 62.6% (107/171 of patients with ≥1 DDI and by 55.4% (46/83 of patients with no DDIs. Gastrointestinal AEs (upper and lower were reported in 5.3% (9/171 and 7.2% (6/83, cardiovascular AEs in 4.7% (8/171 and 1.2% (1/83, renal AEs in 1.2% (2/171 and 0%, and hepatic AEs in 0% and 1.2% (1/83 of patients with ≥1 DDI compared with patients with no DDIs, respectively. Conclusion: Concurrent use of DSG with medications that had potential for major to moderate DDIs had little impact on

    Purpose: Thalidomide has been demonstrated to possess antitumor activity in patients with advanced hepatocellular carcinoma (HCC). The objective of the present study was to determine whether the combined treatment of thalidomide with radiotherapy (RT) is associated with acceptable toxicity and an improved clinical outcome in HCC patients. Methods and Materials: A total of 24 patients were enrolled to receive RT combined with thalidomide. A total dose of 50 Gy was delivered in 2-Gy fractions within 5 weeks. Thalidomide was administered 100 mg twice daily starting 3 days before RT until the development of unacceptable toxicity or disease progression. Blood samples were collected before, during, and after treatment to measure the levels of angiogenic factors and cytokines. The results of patients receiving the combined therapy were compared with those from 18 HCC patients receiving RT only. Results: No significant difference in the clinical parameters was noted between the two groups, except for the baseline interleukin-6 level, which was greater in the concomitant group (p = .05). The most common toxicities related to thalidomide use were skin rash (54.2%), somnolence (37.5%), and constipation (33.3%). No significant differences were seen in the response rate (55.6% vs. 58.3%, p = .48), median progression-free survival (182 {+-} 48.9 vs. 148 {+-} 6.2 days, p = .15), or median overall survival (258 {+-} 45.6 vs. 241 {+-} 38.6, p = .16) between those who received concomitant therapy and those who received RT alone. Thalidomide suppressed the serum basic fibroblast growth factor level significantly during RT (p = .03) and, to a lesser extent, the interleukin-6 and tumor necrosis factor-{alpha} levels. After adjusting for other potential prognostic factors in the multivariate analysis, only the baseline interleukin-6 level and stem cell-derived factor-1 during RT independently predicted the progression-free survival.

    Cyclosporine (CS) is widely used in patients with refractory atopic dermatitis (AD). During CS treatment, many patients have a tendency to decrease their adherence to topical agents as their disease improves. Our aim was to compare the efficacy and relapse rate of CS treatment combined with topical therapy and CS monotherapy. This prospective, randomized, 6 month study involved 60 patients with moderate-to-severe AD who were randomly assigned to two groups, one receiving CS and topical agents and the other, CS only. Clinical outcomes were based on investigators' global assessment (IGA) scores, eczema areas and severity index scores, and trans-epidermal water loss. If a patient achieved treatment success (IGA score ≤2) during the study period, CS was stopped. Relapse rate and time to relapse were evaluated during the 3 months after discontinuation of CS. The treatment success rate was significantly higher in the combination group (p = 0.028). The combination group had a shorter median time to response (p = 0.040), a lower cumulative dose (p = 0.041), and a longer time to relapse (p topical agents should be used concomitantly.

    This study aimed to analyze the treatment and outcomes of older glioblastoma patients. Forty-four patients older than 70 years of age were referred to the Paul Strauss Center for chemotherapy and radiotherapy. The median age was 75.5 years old (range: 70–84), and the patients included 18 females and 26 males. The median Karnofsky index (KI) was 70%. The Charlson indices varied from 4 to 6. All of the patients underwent surgery. O{sub 6}-methylguanine–DNA methyltransferase (MGMT) methylation status was determined in 25 patients. All of the patients received radiation therapy. Thirty-eight patients adhered to a hypofractionated radiation therapy schedule and six patients to a normofractionated schedule. Neoadjuvant, concomitant and adjuvant chemotherapy regimens were administered to 12, 35 and 20 patients, respectively. At the time of this analysis, 41 patients had died. The median time to relapse was 6.7 months. Twenty-nine patients relapsed, and 10 patients received chemotherapy upon relapse. The median overall survival (OS) was 7.2 months and the one- and two-year OS rates were 32% and 12%, respectively. In a multivariate analysis, only the Karnofsky index was a prognostic factor. Hypofractionated radiotherapy and chemotherapy with temozolomide are feasible and acceptably tolerated in older patients. However, relevant prognostic factors are needed to optimize treatment proposals.

  6. RDW as differential parameter between microcytic anemias in "pure" and concomitant forms

    Full Text Available Introduction: Iron deficiency anemia and thalassemia minor are microcytic and hypochromic types of anemia commonly found in our environment. The correct differentiation between them is of great clinical importance, although it is often hampered by the coexistence of diseases that may alter the results of standard tests for their discrimination, in addition to the significant costs of such tests. Objective: The objective of this study was to investigate the discriminatory power of red cell distribution width (RDW between iron deficiency anemia and thalassemia minor. Method: Blood parameters were compared in 227 patients with iron deficiency anemia and/or thalassemia minor after diagnosis confirmed by molecular biology and HbA2 measurement for alpha thalassemia and beta thalassemia trait respectively. The frequency of alpha thalassemia trait in a population from two public hospitals of Minas Gerais was also determined. Result and conclusion: RDW was able to differentiate iron deficiency anemia from thalassemia trait, what indicates that this blood count parameter is a useful tool since concomitant disorders are excluded. In addition, a high frequency of the -α3.7 mutation was observed in the study population (20.3%, justifying its investigation when another cause for microcytic anemia is absent.

    Given the importance of RNA secondary structures in defining their biological role, it would be convenient for researchers seeking RNA data if both sequence and structural information pertaining to RNA molecules are made available together. Current nucleotide data repositories archive only RNA sequence data. Furthermore, storage formats which can frugally represent RNA sequence as well as structure data in a single file, are currently unavailable. This article proposes a novel storage format, `FASTR’, for concomitant representation of RNA sequence and structure. The storage efficiency of the proposed FASTR format has been evaluated using RNA data from various microorganisms. Results indicate that the size of FASTR formatted files (containing both RNA sequence as well as structure information) are equivalent to that of FASTA-format files, which contain only RNA sequence information. RNA secondary structure is typically represented using a combination of a string of nucleotide characters along with the corresponding dot-bracket notation indicating structural attributes. `FASTR’ – the novel storage format proposed in the present study enables a frugal representation of both RNA sequence and structural information in the form of a single string. In spite of having a relatively smaller storage footprint, the resultant `fastr’ string(s) retain all sequence as well as secondary structural information that could be stored using a dot-bracket notation. An implementation of the `FASTR’ methodology is available for download at http://metagenomics.atc.tcs.com/compression/fastr.

    A 72-year-old woman referred to our hospital because of slowly progressive (over 2 years) muscle weakness and paresthesias of the lower limbs. On neurological examination, weakness and muscle atrophies were noted in the distal upper limbs as well as the proximal lower limbs. She had also paresthesias of the legs. The level of creatinine phosphokinase (CK) was 126 IU/l. The magnetic resonance imaging demonstrated gadolinium enhancement of the nerve roots at the L4-S2 vertebrate levels. Nerve conduction study showed decreased compound muscle action potential and motor conduction velocity of tibial and peroneal nerves. Biopsy of the left biceps brachii muscle showed variations in fiber size, endomysial mononuclear cell infiltration and the findings like a rimmed vacuole. Although almost of her findings were in accord with clinical features of inclusion body myositis, strong inflammatory cellular influences allowed us to administer corticosteroid therapy. Because her weakness was well responded to steroid therapy, polymyositis was considered as differential diagnosis. Then, further examinations were investigated to search any occult neoplasm, and detected the early gastric cancer. Total gastrectomy was performed later, and the pathological diagnosis was made as a signet-ring cell carcinoma. To our knowledge, this is the first report of systemic myositis and subacute sensory neuropathy concomitant with signet-ring cell carcinoma. These symptoms might be occurred as a result of paraneoplastic syndrome associated with satellite effects of the signet-ring cell carcinoma. PMID:20411807

    For a long time, combined external irradiation and brachytherapy has been considered as the standard treatment in patients with advanced cervical cancers. Recently, five clinical randomized trials assessing the role of cis-platin-based chemotherapy delivered concomitantly to radiotherapy have been conducted in the United States. Another clinical randomized trial assessing the role of epirubicin was conducted by the Queen Mary Hospital in Hong Kong. With more than 2,000 enrolled patients, these studies showed converging results with an overall and disease-free survival improvement in the arms combining cis-platin and epirubicin-based chemotherapy and irradiation. These combinations led to a significant decrease in loco-regional evolution or recurrence rates, or even in pulmonary metastases rates. The relative risk of recurrences was decreased by 50%. The relative risk of death was decreased by 40%. The differences, however, were less significant in patients with advanced stages III or IVA. Hematological and digestive acute toxicity was significantly higher in the radiochemotherapy groups, but long-term complications were comparable. The results of these randomized trials have led to a modification in the standard of treatment in these poor prognosis cervix cancers. Five of the randomized trials evidenced the superiority of cis-platin-based chemotherapy, but the optimal chemotherapeutic regimens remain to be defined.

    To examine the role of gap junctions in cell senescence,the changes of gap junctions in cisplatin-induced premature senescence of primary cultured fibroblasts were studied and compared with the replicative senescent human fibroblasts.Dye transfer assay for gap junction function and immunofluorescent staining for connexin 43 protein distribution were done respectively. Furthermore,cytofluorimetry and DAPI fluorescence staining were performed for cell cycle and apoptosis analysis. p53 gene expression level was detected with indirect immunofluorescence. We found that cisplatin (10 mM) treatment could block cell growth cycle at G1 and induced premature senescence. The premature senescence changes included high frequency of apoptosis,elevation of p53 expression,loss of membranous gap junctions and reduction of dye-transfer capacity. These changes were comparable to the changes of replicative senescence of human fibroblasts. It was also concluded that cisplatin could induce premature senescence concomitant with inhibition of gap junctions in the fibroblasts. Loss of functional gap junctions from the cell membrane may account for the reduced intercellular communication in the premature senescent fibroblasts. The cell system we used may provide a model useful for the study of the gap junction thus promoting agents against premature senescence.

    Full Text Available Chronic Q fever is a potentially life-threatening infection from the intracellular, Gram-negative Coxiella burnetii. It presents most commonly as endocarditis or vascular infection in people with underlying cardiac or vascular disease. We discuss a case of a 67-year-old male with Coxiella burnetii vascular infection of a perirenal abdominal aortic graft. The patient had a history of an abdominal aortic aneurysm (AAA repair 5 years earlier. He presented with a 12 × 6 × 8 cm perirenal pseudoaneurysm and concomitant L1, L2, and L3 vertebral body discitis. He underwent an open repair which revealed a grossly infected graft perioperatively. Q fever serology revealed phase I serological IgG titer of 1 : 2048 and phase II 1 : 1024 consistent with chronic Q fever. Polymerase chain reaction (PCR on infected vascular tissue was positive for C. burnetii. The patient was started on doxycycline and hydroxychloroquine with good clinical response and decreasing serological titers. Recognizing chronic Q fever is a difficult task as symptoms are nonspecific, exposure risk is difficult to ascertain, and diagnosis is hidden from conventional microbiological investigations. Its recognition, however, is critical as C. burnetii is inherently resistant to standard empiric therapies used in cardiovascular infections.

    51 patients with gastric cancer and severe concomitant ischemic heart disease (90.2%), valvular heart disease (5.9%), critical stenosis of the internal carotid artery (2%) or abdominal aortic aneurism (2%) were operated on during 1995-2011yy. Of them men were 41, women - 10; mean age was 65.1 years (51-82). The first stage of gastric cancer was diagnosed in 18 (35.3%) of patients, second, third and fourth in 12 (23.5%), 17 (33.3%) and 4 (7.8%), respectively. Radical tumor resection was achieved in 37 (72.5%), palliative operations were performed in 13 (25.5%) patients. 17.6% of patients were operated on stomach and vessels simultaneously. 82.4% received the stepwise treatment. Intra- and postoperative complications were registered in 47.1% (24 of 51 patients); of whom 5.9% (3 patients) ended lethally. Simultaneous operations showed the 55.6% complications and zero lethality rate, whereas stepwise treatment resulted in 45.2% complications and 7.1% lethality. PMID:24077499

    Polarized epithelia form by oriented cell divisions in which the mitotic spindle aligns parallel to the epithelial plane. To orient the mitotic spindle, cortical cues trigger the recruitment of NuMA-dynein-based motors, which pull on astral microtubules via the protein LGN. We demonstrate that the junctional protein Afadin is required for spindle orientation and correct epithelial morphogenesis of Caco-2 cysts. Molecularly, Afadin binds directly and concomitantly to F-actin and to LGN. We determined the crystallographic structure of human Afadin in complex with LGN and show that it resembles the LGN-NuMA complex. In mitosis, Afadin is necessary for cortical accumulation of LGN and NuMA above the spindle poles, in an F-actin-dependent manner. Collectively, our results depict Afadin as a molecular hub governing the enrichment of LGN and NuMA at the cortex. To our knowledge, Afadin is the first-described mechanical anchor between dynein and cortical F-actin. PMID:26751642

    We report a case of chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) concomitant with acquired von Willebrand syndrome. A 33-year-old man developed motor and sensory polyneuropathy with electrophysiological conduction slowing. At this time, M-protein was absent He was diagnosed with CIDP and received intravenous immunoglobulin and subsequent oral corticosteroids, which resulted in almost complete remission for over 10 years. At the age of 44, he presented with chronic anemia. Laboratory tests and colonoscopy revealed that he had acquired von Willebrand syndrome with monoclonal gammopathy of undetermined significance (IgG lambda type) and colon cancer. Bleeding symptoms were.resolved with intravenous immunoglobulin, but not with supplementation of factor VIII. Shortly after successful excision of the cancer, CIDP and acquired von Willebrand syndrome simultaneously recurred. Intravenous immunoglobulin produced rapid improvement of both neurological and hematological abnormalities. Concurring CIDP and acquired von Willebrand syndrome in the present case may indicate that the conditions have a partly common immunological background including monoclonal gammopathy and a potential common autoantibody-mediated mechanism. Alternatively, dysfunction of von Willebrand factor may increase blood-nerve barrier permeability, inducing the recurrence of CIDP.

The patient had a history of an abdominal aortic aneurysm (AAA) repair 5 years earlier. He presented with a 12 × 6 × 8 cm perirenal pseudoaneurysm and concomitant L1, L2, and L3 vertebral body discitis. He underwent an open repair which revealed a grossly infected graft perioperatively. Q fever serology revealed phase I serological IgG titer of 1 : 2048 and phase II 1 : 1024 consistent with chronic Q fever. Polymerase chain reaction (PCR) on infected vascular tissue was positive for C. burnetii. The patient was started on doxycycline and hydroxychloroquine with good clinical response and decreasing serological titers. Recognizing chronic Q fever is a difficult task as symptoms are nonspecific, exposure risk is difficult to ascertain, and diagnosis is hidden from conventional microbiological investigations. Its recognition, however, is critical as C. burnetii is inherently resistant to standard empiric therapies used in cardiovascular infections. PMID:27366178

    To assess the outcomes of endovascular aortic aneurysm repair (EVAR) for the treatment of an abdominal aortic aneurysm in patients undergoing curative surgical treatment for concomitant abdominal malignancy. The study included 12 patients with abdominal neoplasia and an abdominal aortic aneurysm (AAA), which was treated by surgery and stent EVAR. The neoplasm consisted of the gastric, colorectal, pancreas, prostate, and gall bladder. The follow up period was 3-21 months (mean 11.8 months). All medical records and imaging analyses were reviewed by CTA and/or color Doppler US, retrospectively. Successful endoluminal repair was accomplished in all twelve patients. The mean interval time between EVAR and surgery was 58.6 days. Small amounts of type 2 endoleaks were detected in two patients (17%). One patient developed adult respiratory distress syndrome after Whipple's operation 20 days after surgery, which led to hopeless discharge. No procedure-related mortality, morbidity, or graft-related infection was noted. Exclusion of AAA in patients with accompanying malignancy show with a relatively low procedure morbidity and mortality. Hence, endoluminal AAA repair in patients with synchronous neoplasia may allow greater flexibility in the management of an offending malignancy

    Full Text Available Frequently reported H. pylori antimicrobial therapy failures suggest that there might be a different niche where the bacteria can stay safe. Current study aims to examine potential role of oral colonization of H. pylori to feed reinfection after primary therapy. However, patients who were admitted to the gastroscopy section were chosen and gastric biopsy and dental plaque specimens were collected. Molecular and biochemical tests were applied to confirm H. pylori identity in different colonization niches. Results showed that 88.8% of dyspeptic patients had epigastric pains with nocturnal awakening when they were hungry (P=0.023. All patients who received therapy already were again H. pylori positive while they are still carrying H. pylori in dental plaque (P=0.001. Moreover, H. pylori infection was sought in 100% of gastric biopsy’s dyspeptic patients who had ulcerated esophagitis and erosive duodenitis and who were H. pylori positive, and 75% of dyspeptic patients with duodenum deformity had this bacterium in gastric biopsies (P=0.004. Present study showed that only successful eradication of gastric H. pylori cannot guarantee prevention of reinfection. Conclusively, a new strategy which indicates concomitant eradication in oral and gastric colonization can result in clearance of H. pylori infection.

    Full Text Available The present study was aimed to evaluate the combined effects of simvastatin (SIM and ethanol extract of Zingiber officinale (ZO in doxorubicin (DOX induced cardiotoxicity in Wistar rats. DOX 10 mg/kg i.p single dose to causes cardiac damage and increases the levels of cardiac biomarker enzymes viz. ALT, AST, LDH and CKMB. In addition, a significant rise in HR, ST- segment and alterations in ECG patterns were observed in DOX treated group. SIM (1.8 mg/kg & 3.6 mg/kg and ZO (200 mg/kg & 400 mg/kg alone and in combination were given to rats as pretreatment for 30 days orally. Pretreatment with SIM and ZO alone significantly (P<0.001 reduced the elevated serum biomarker enzyme levels and ECG alterations in DOX induced cardiotoxic rats. But, combined pretreatment with SIM and ZO normalized the biochemical parameters and ECG changes in DOX induced cardiotoxic rats. The result obtained from the present study indicates concomitant pretreatment of SIM and ZO showed significant improvement than single treatment.

  19. Outcomes in Newly Diagnosed Elderly Glioblastoma Patients after Concomitant Temozolomide Administration and Hypofractionated Radiotherapy

    International Nuclear Information System (INIS)

    This study aimed to analyze the treatment and outcomes of older glioblastoma patients. Forty-four patients older than 70 years of age were referred to the Paul Strauss Center for chemotherapy and radiotherapy. The median age was 75.5 years old (range: 70–84), and the patients included 18 females and 26 males. The median Karnofsky index (KI) was 70%. The Charlson indices varied from 4 to 6. All of the patients underwent surgery. O6-methylguanine–DNA methyltransferase (MGMT) methylation status was determined in 25 patients. All of the patients received radiation therapy. Thirty-eight patients adhered to a hypofractionated radiation therapy schedule and six patients to a normofractionated schedule. Neoadjuvant, concomitant and adjuvant chemotherapy regimens were administered to 12, 35 and 20 patients, respectively. At the time of this analysis, 41 patients had died. The median time to relapse was 6.7 months. Twenty-nine patients relapsed, and 10 patients received chemotherapy upon relapse. The median overall survival (OS) was 7.2 months and the one- and two-year OS rates were 32% and 12%, respectively. In a multivariate analysis, only the Karnofsky index was a prognostic factor. Hypofractionated radiotherapy and chemotherapy with temozolomide are feasible and acceptably tolerated in older patients. However, relevant prognostic factors are needed to optimize treatment proposals

  10. Risk factors of radiation-induced acute esophagitis in non-small cell lung cancer patients treated with concomitant chemoradiotherapy

    International Nuclear Information System (INIS)

    To analyze the clinical and dosimetric risk factors of acute esophagitis (AE) in non-small-cell lung cancer (NSCLC) patients treated with concomitant chemoradiotherapy. Seventy-six NSCLC patients treated with concomitant chemoradiotherapy were retrospectively analyzed. Forty-one patients received concomitant chemoradiotherapy with vinorelbine/cisplatin (VC), 35 with docetaxel/cisplatin (DC). AE was graded according to criteria of the Radiation Therapy Oncology Group (RTOG). The following clinical and dosimetric parameters were analyzed: gender, age, clinical stage, Karnofsky performance status (KPS), pretreatment weight loss, concomitant chemotherapy agents (CCA) (VC vs. DC), percentage of esophagus volume treated to ≥20 (V20), ≥30 (V30), ≥40 (V40), ≥50 (V50) and ≥60 Gy (V60), and the maximum (Dmax) and mean doses (Dmean) delivered to esophagus. Univariate and multivariate logistic regression analysis were used to test the association between the different factors and AE. Seventy patients developed AE (Grade 1, 19 patients; Grade 2, 36 patients; and Grade 3, 15 patients). By multivariate logistic regression analysis, V40 was the only statistically significant factor associated with Grade ≥2 AE (p<0.001, OR = 1.159). A V40 of <23% had a 33.3% (10/30) risk of Grade ≥2 AE, which increased to 89.1% (41/46) with a V40 of ≥23% (p<0.001). CCA (p =0.01; OR = 9.686) and V50 (p<0.001; OR = 1.122) were most significantly correlated with grade 3 AE. A V50 of <26.5% had a 6.7% (3/45) risk of Grade 3 AE, which increased to 38.7% (12/31) with a V50 of ≥26.5% (p = 0.001). On the linear regression analysis, V50 and CCA were significant independent factors affecting AE duration. Patients who received concomitant chemotherapy with VC had a decreased risk of grade 3 AE and shorter duration compared with DC. Concomitant chemotherapy agents have potential influence on AE. Concomitant chemotherapy with VC led to lower risk of AE compared with that using DC. V40 and V50

    Background: Common bile duct stone (CBDS) as a result of gallstone is one of the gastrointestinal disorders. In this study, the incidence of CBDS and symptomatic gallstone in Shiraz were investigated, and their management suggested. Materials and Methods: This is a retrospective study that enrolled among 560 patients. The incidence of gallstone together with CBDS was evaluated using an ultrasonography studyand clinical data in the period between March 2014 and 2014 in Shiraz. Comparison between data was done using Student’s t-test or Chi-square test. Results: Of these patients, 18.6% were male, and 81.4% were female with a mean age of 47.67 ± 0.74 years. The concomitant rate of gallstone and CBDS was 8.6%. 6.8% of patients with concomitant of gallstone and CBDS showed symptoms while 1.8% had not been diagnosed before the operation. The mean of serum alkaline phosphatase level in patients with the only gallstone was 255.80 IU/L and patients with concomitant gallstone, and CBDS was 580.88 IU/L with a significant difference between two groups (P < 0.001). Furthermore, liver function tests (aspartate aminotransferase, alanine transaminase) showed a significant difference between two groups of patients (P < 0.01, P < 0.001). Conclusions: Clinical variables such as tenderness, fever, and Morphy sign were more severein patients with concomitant gallstone and CBDS. The concomitant rate of gallstone and CBDS in our society is less that Western countries and asymptomatic patients showed fewer ratios than other countries. We think the approach for asymptomatic CBDS patients with gallstone can be affected by our results. PMID:27656616

    Background:Both hormonal therapy (HT) and maintenance capecitabine monotherapy (MCT) have been shown to extend time to progression (TTP) in patients with metastatic breast cancer (MBC) after failure of taxanes and anthracycline‑containing regimens. However, no clinical trials have directly compared the effcacy of MCT and HT after response to ifrst‑line capecitabine‑based combination chemotherapy (FCCT) in patients with hormone receptor (HR)‑positive and human epidermal growth factor receptor 2 (HER2)‑negative breast cancer. Methods:We retrospectively analyzed the charts of 138 HR‑positive and HER2‑negative MBC patients who were in non‑progression status after FCCT and who were treated between 2003 and 2012 at the Cancer Institute and Hospital, Chinese Academy of Medical Sciences, in Beijing, China. The median number of ifrst‑line chemotherapy cycles was 6 (range, 4–8); combined agents included taxanes, vinorelbine, or gemcitabine. Of these 138 patients, 79 received MCT, and 59 received HT. Single‑agent capecitabine was administered at a dose of 1250mg/m2 twice daily for 14days, followed by a 7‑day rest period, repeated every 3weeks. Of the 59 patients who received HT, 37 received aromatase inhibitors (AIs), 8 received selective estrogen receptor modulators (SERMs), and 14 received goserelin plus either AIs or SERMs. We then compared the MCT group and HT group in terms of treatment effcacy. Results:With a median follow‑up of 43months, patients in the HT group had a much longer TTP than patients in the MCT group (13 vs. 8months,P=0.011). When TTP was adjusted for age, menopausal status, Karnofsky performance status score, disease‑free survival, site of metastasis, number of metastatic sites, and response status after FCCT, extended TTP was still observed for patients in the HT group (hazard ratio: 0.63; 95% conifdence interval: 0.44–0.93;P=0.020). We also observed a trend of overall survival advantage for patients in the HT group vs

    Purpose: To evaluate the rate of gastrointestinal (GI) toxicity of neoadjuvant chemoradiation with capecitabine, oxaliplatin, and intensity modulated radiation therapy (IMRT) in cT3-4 rectal cancer. Methods and Materials: Patients with localized, nonmetastatic T3 or T4 rectal cancer <12 cm from the anal verge were enrolled in a prospective, multi-institutional, single-arm study of preoperative chemoradiation. Patients received 45 Gy with IMRT in 25 fractions, followed by a 3-dimensional conformal boost of 5.4 Gy in 3 fractions with concurrent capecitabine/oxaliplatin (CAPOX). Surgery was performed 4 to 8 weeks after the completion of therapy. Patients were recommended to receive FOLFOX chemotherapy after surgery. The primary endpoint of the study was acute grade 2 to 5 GI toxicity. Seventy-one patients provided 80% probability to detect at least a 12% reduction in the specified GI toxicity with the treatment of CAPOX and IMRT, at a significance level of .10 (1-sided). Results: Seventy-nine patients were accrued, of whom 68 were evaluable. Sixty-one patients (89.7%) had cT3 disease, and 37 (54.4%) had cN (+) disease. Postoperative chemotherapy was given to 42 of 68 patients. Fifty-eight patients had target contours drawn per protocol, 5 patients with acceptable variation, and 5 patients with unacceptable variations. Thirty-five patients (51.5%) experienced grade ≥2 GI toxicity, 12 patients (17.6%) experienced grade 3 or 4 diarrhea, and pCR was achieved in 10 patients (14.7%). With a median follow-up time of 3.98 years, the 4-year rate of locoregional failure was 7.4% (95% confidence interval [CI]: 1.0%-13.7%). The 4-year rates of OS and DFS were 82.9% (95% CI: 70.1%-90.6%) and 60.6% (95% CI: 47.5%-71.4%), respectively. Conclusion: The use of IMRT in neoadjuvant chemoradiation for rectal cancer did not reduce the rate of GI toxicity.

    We have recently demonstrated that AR-12 (OSU-03012) reduces the function and ATPase activities of multiple HSP90 and HSP70 family chaperones. Combined knock down of chaperones or AR-12 treatment acted to reduce the expression of virus receptors and essential glucosidase proteins. Combined knock down of chaperones or AR-12 treatment inactivated mTOR and elevated ATG13 S318 phosphorylation concomitant with inducing an endoplasmic reticulum stress response that in an eIF2α-dependent fashion increased Beclin1 and LC3 expression and autophagosome formation. Over-expression of chaperones prevented the reduction in receptor/glucosidase expression, mTOR inactivation, the ER stress response, and autophagosome formation. AR-12 reduced the reproduction of viruses including Mumps, Influenza, Measles, Junín, Rubella, HIV (wild type and protease resistant), and Ebola, an effect replicated by knock down of multiple chaperone proteins. AR-12-stimulated the co-localization of Influenza, EBV and HIV virus proteins with LC3 in autophagosomes and reduced viral protein association with the chaperones HSP90, HSP70, and GRP78. Knock down of Beclin1 suppressed drug-induced autophagosome formation and reduced the anti-viral protection afforded by AR-12. In an animal model of hemorrhagic fever virus, a transient exposure of animals to low doses of AR-12 doubled animal survival from ∼30% to ∼60% and suppressed liver damage as measured by ATL, GGT and LDH release. Thus through inhibition of chaperone protein functions; reducing the production, stability and processing of viral proteins; and stimulating autophagosome formation/viral protein degradation, AR-12 acts as a broad-specificity anti-viral drug in vitro and in vivo. We argue future patient studies with AR-12 are warranted. J. Cell. Physiol. 231: 2286-2302, 2016. © 2016 Wiley Periodicals, Inc. PMID:27187154

    Full Text Available This study was conducted to investigate the feasibility and survival benefits of combined treatment with radiotherapy and temozolomide (TMZ, which has been covered by the national health insurance in Japanese patients with glioblastoma since September 2006. Between September 2006 and December 2011, 47 patients with newly diagnosed and histologically confirmed glioblastoma received radiotherapy for 60 Gy in 30 fractions. Among them, 45 patients (TMZ group received concomitant TMZ (75 mg/m(2/day, every day and adjuvant TMZ (200 mg/m(2/day, 5 days during each 28-days. All 36 of the glioblastoma patients receiving radiotherapy between January 1988 and August 2006 were analyzed as historical controls (control group. All patients were followed for at least 1 year or until they died. The median survival was 15.8 months in the TMZ group and 12.0 months in the control group after a median follow-up of 14.0 months. The hazard ratio for death in the TMZ group relative to the control group was 0.52 (P<0.01; the 2-year survival rate was 27.7% in the TMZ group and 14.6% in the control group. Hematologic toxicity of grade 3 and higher was observed in 20.4% in the TMZ group. Multivariate analysis showed that extent of surgery had the strongest impact on survival (P<0.01, while the use of TMZ had the second largest impact on survival (P = 0.035. The results indicate that combined treatment with radiotherapy and TMZ has a significant survival benefit for Japanese patients with newly diagnosed glioblastoma with slightly higher toxicities than previously reported.

  18. A single centre experience with sequential and concomitant chemoradiotherapy in locally advanced stage IV tonsillar cancer

    International Nuclear Information System (INIS)

    Chemo-radiotherapy offers an alternative to primary surgery and adjuvant therapy for the management of locally advanced stage IV squamous cell carcinomas of the tonsil. A retrospective analysis was performed of the outcomes of 41 patients with locoregionally advanced squamous cell carcinoma of the tonsil treated non-surgically at the Yorkshire Cancer Centre between January 2004 and December 2005. Due to long radiotherapy waiting times, patients received induction chemotherapy with cisplatin and 5-fluorouracil followed by either cisplatin concurrent chemoradiotherapy or radiotherapy alone. Median age was 55 years (range 34-76 years) and 28 (68%) patients were male. 35/41 patients (85%) received 2 or more cycles of induction chemotherapy. Following induction chemotherapy, 32/41 patients (78%) had a clinical response. Concomitant chemotherapy was given to 30/41 (73%). All patients received the planned radiotherapy dose with no delays. There were no treatment related deaths. Six (15%) patients had gastrostomy tubes placed before treatment, and 22 (54%) required nasogastric tube placement during or after treatment for nutritional support. 17 patients required unplanned admissions during treatment for supportive care. At 4 months post treatment assessment 35 out of 41 (85%) patients achieved complete clinical and radiographic response. Median follow-up is 38 months (8-61 months). Local and regional control rate in complete responders at 3 years was 91%. Distant metastases have been found in 4 (9.8%) patients. Three year progression-free survival rate in all patients is 75%. The 3-year cause specific survival and overall survival are 75% and 66% respectively. Cisplatin-based induction and concurrent chemoradiotherapy provides excellent tumour control with acceptable toxicity for patients with locally advanced tonsillar cancer

    Full Text Available Abstract Background Diabetes mellitus and renal dysfunction are prognostic factors after acute myocardial infarction (AMI. However, few studies have assessed the effects of renal insufficiency in association with diabetes in the context of AMI. Here, we investigated the clinical outcomes according to the concomitance of renal dysfunction and diabetes mellitus in patients with AMI. Methods From November 2005 to August 2008, 9905 patients (63 ± 13 years; 70% men with AMI were enrolled in a nationwide prospective Korea Acute Myocardial Infarction Registry (KAMIR and were categorized into 4 groups: Group I (n = 5700 had neither diabetes nor renal insufficiency (glomerular filtration rate [GFR] ≥ 60 ml/min/1.73 m2, Group II (n = 1730 had diabetes but no renal insufficiency, Group III (n = 1431 had no diabetes but renal insufficiency, and Group IV (n = 1044 had both diabetes and renal insufficiency. The primary endpoints were major adverse cardiac events (MACE, including a composite of all cause-of-death, myocardial infarction, target lesion revascularization, and coronary artery bypass graft after 1-year clinical follow-up. Results Primary endpoints occurred in 1804 (18.2% patients. There were significant differences in composite MACE among the 4 groups (Group I, 12.5%; Group II, 15.7%; Group III, 30.5%; Group IV, 36.5%; p p = 0.001; and HR, 2.42; 95% CI, 1.62-3.62; p Conclusions Renal insufficiency, especially in association with diabetes, is associated with the occurrence of composite MACE and indicates poor prognosis in patients with AMI. Categorization of patients with diabetes and/or renal insufficiency provides valuable information for early-risk stratification of AMI patients.

  20. Concomitant duplications of opioid peptide and receptor genes before the origin of jawed vertebrates.

    Directory of Open Access Journals (Sweden)

    Görel Sundström

    Full Text Available BACKGROUND: The opioid system is involved in reward and pain mechanisms and consists in mammals of four receptors and several peptides. The peptides are derived from four prepropeptide genes, PENK, PDYN, PNOC and POMC, encoding enkephalins, dynorphins, orphanin/nociceptin and beta-endorphin, respectively. Previously we have described how two rounds of genome doubling (2R before the origin of jawed vertebrates formed the receptor family. METHODOLOGY/PRINCIPAL FINDINGS: Opioid peptide gene family members were investigated using a combination of sequence-based phylogeny and chromosomal locations of the peptide genes in various vertebrates. Several adjacent gene families were investigated similarly. The results show that the ancestral peptide gene gave rise to two additional copies in the genome doublings. The fourth member was generated by a local gene duplication, as the genes encoding POMC and PNOC are located on the same chromosome in the chicken genome and all three teleost genomes that we have studied. A translocation has disrupted this synteny in mammals. The PDYN gene seems to have been lost in chicken, but not in zebra finch. Duplicates of some peptide genes have arisen in the teleost fishes. Within the prepropeptide precursors, peptides have been lost or gained in different lineages. CONCLUSIONS/SIGNIFICANCE: The ancestral peptide and receptor genes were located on the same chromosome and were thus duplicated concomitantly. However, subsequently genetic linkage has been lost. In conclusion, the system of opioid peptides and receptors was largely formed by the genome doublings that took place early in vertebrate evolution.

    Full Text Available OBJECTIVE: Cardiovascular risk increases with the presence of both metabolic syndrome (MetS and hypertension (HTN. Although the adiponectin (ADIPOQ gene has been reported to be involved in MetS, its association with HTN remained undetermined. This study aimed to investigate the association of ADIPOQ gene with the phenotypes of HTN and MetS. METHODS: A total of 962 participants from 302 families from the Taiwan young-onset hypertension genetic study were enrolled. Plasma adiponectin were measured, and association analysis was conducted by using GEE regression-based method. Another study, of 1448 unrelated participants, was conducted to replicate the association between ADIPOQ gene and variable phenotypes of MetS with or without HTN. RESULTS: Among 962 subjects from family samples, the lowest plasma adiponectin value was observed in MetS with HTN component (9.3±0.47 µg/ml compared with hypertensives (13.4±0.74 µg /ml or MetS without HTN (11.9±0.60 µg/ml, P<0.05. The SNP rs1501299 (G276T in ADIPOQ gene was found associated with the presence of HTN in MetS (odds ratio for GG+GT vs. TT = 2.46; 95% CI: 1.14-5.3, p = 0.02, but not rs2241766 (T45G. No association of ADIPOQ gene with HTN alone or MetS without HTN was observed. The significant association of the SNP rs1501299 (G276T with the phenotype of presence of HTN in MetS was confirmed (odds ratio for GG+GT vs. TT = 2.15; 95% CI: 1.1-4.3 in the replication study. CONCLUSIONS: ADIPOQ genetic variants were selectively and specifically associated with the concomitant presence of MetS and HTN, suggesting potential genetic linkage between MetS and HTN.

    The coexistence of thyroid diseases with primary hyperparathyroidism (PHPT) can present a challenge in the clinical diagnosis and management for these patients. This study aims to determine the frequency of coexisting thyroid gland lesions in a consecutive series patients with PHPT, and to analyze the clinical features, diagnosis and treatment of these patients. Twenty-two cases of a total of 52 PHPT patients who had synchronous thyroid and parathyroid pathology were surgically managed in this study.Thirteen patients had ipsilateral thyroid nodules, and 9 patients had thyroid nodules in contralateral or bilateral side. Seven patients underwent direct parathyroidectomy and hemithyroidectomy via a mini-incision (about 3 cm), while other 15 procedures were converted to Kocher incision. Seventeen nodular goiter (32.7%), 2 thyroiditis (3.8%), 2 thyroid adenoma (3.8%) and 1 thyroid carcinoma (1.9%) coexisting with parathyroid adenoma were pathologically diagnosed. The sensitivity of preoperative ultrasonography (US) and methoxy-isobutyl-isonitrile (MIBI) scintigraphy for parathyroid lesions was 63.6% and 85.7%; and the overall positive predictive values for MIBI and US were 100% and 95.5% respectively. A high incidence of thyroid diseases that coexisted with PHPT in literatures was briefly reviewed. Our study illustrated the need for clinical awareness of concomitant PHPT and thyroid disease. A combination of US, computed tomography (CT) and MIBI scintigraphy would be recommended for preoperative localization of enlarged parathyroid adenoma and for evaluation of thyroid lesions. Synchronous treatment of associated thyroid abnormalities is desirable, and open minimally invasive surgical approach with additional resection of isolated ipsilateral thyroid nodules is possible in some of these patients.

  4. Phase 1 Clinical Trial of Stereotactic Body Radiation Therapy Concomitant With Neoadjuvant Chemotherapy for Breast Cancer

    International Nuclear Information System (INIS)

    Purpose: Stereotactic body radiation therapy (SBRT) allows stereotactic irradiation of thoracic tumors. It may have a real impact on patients who may not otherwise qualify for breast-conserving surgery. We conducted a phase 1 trial that tested 5 dose levels of SBRT concomitant with neoadjuvant chemotherapy (NACT) before to surgery. The purpose of the current dose escalation study was to determine the maximum tolerable dose of SBRT in the treatment of breast cancer. Methods and Materials: To define toxicity, we performed dermatologic examinations that included clinical examinations by 2 separate physicians and technical evaluations using colorimetry, dermoscopy, and skin ultrasonography. Dermatologic examinations were performed before NACT, 36 and 56 days after the beginning of NACT, and before surgery. Surgery was performed 4 to 8 weeks after the last chemotherapy session. Efficacy, the primary endpoint, was determined by the pathologic complete response (pCR) rate. Results: Maximum tolerable dose was not reached. Only 1 case of dose-limiting toxicity was reported (grade 3 dermatologic toxicity), and SBRT was overall well tolerated. The pCR rate was 36%, with none being observed at the first 2 dose levels, and the highest rate being obtained at dose level 3 (25.5 Gy delivered in 3 fractions). Furthermore, the breast-conserving surgery rate was up to 92% compared with an 8% total mastectomy rate. No surgical complications were reported. Conclusions: This study demonstrates that SBRT can be safely combined with NACT. Regarding the efficacy endpoints, this trial showed promising results in terms of pCR rate (36%) and breast-conserving rate (92%). The findings provide a strong rationale for extending the study into a phase 2 trial. In view of the absence of correlation between dose and pCR, and given that the data from dose level 3 met the statistical requirements, a dose of 25.5 Gy in 3 fractions should be used for the phase 2 trial

    In recent years, special attention is paid to comorbid conditions in the clinic of internal diseases. There actively explored the role of endothelial dysfunction as a single unit in the pathological formation of chronic obstructive pulmonary disease (COPD) associated with hypertension. The study involved 145 patients who were carried out the final level of metabolites of nitric oxide (NO2, NO3), S-nitrosothiols, endothelial and inducible NO-synthase. All patients were divided into 3 groups: the first group included 55 patients (35 men and 20 women) who had been diagnosed with COPD with concomitant hypertension - the core group. The average age for this group was 57,6 years (46±68). The comparison group consisted of 45 patients (34 men and 11 women) with isolated course of COPD. The average age for second group was 53,3 years (40±67). The control group consisted of 45 healthy volunteers - 25 men and 20 women. Results of the study of the endothelial dysfunction revealed dynamic change in serum nitrate, nitrite, S-nitrosothiols and activity of eNOS and iNOS as the group of patients with COPD with associated hyperttension and the group of patients with isolated COPD. Informative and prognostic indicators relatively severity of diseases in patients with significant comorbidity may be considered high levels of iNOS and S-nitrosothiols, which indicates the voltage of the functional activity of endogenous antioxidant defense mechanisms in this cohort of persons. The findings suggest that the progression of endothelial dysfunction in comorbidity, which may lead to the current aggravation of diseases and vascular disorders in these patients. PMID:27661272

    Full Text Available Anatomically, brainstem is constituted of medulla oblongata, pons and mesencephalon. Traumatic lesions of brainstem most commonly occur on pontomedullary junction. There are several possible mechanisms of pontomedullary lacerations. The first mechanism includes impact to the chin, with or without a skull base fracture, and most often leads to this fatal injury, due to impact force transmission through the jawbone and temporomandibular joint. The second mechanism includes lateral and posterior head impacts with subsequent hinge fractures, where occurrence of pontomedullary lacerations in these cases may depend on the energy of impact, as well as on the exact position of the fracture line, but less so on the head’s movement. The third mechanism includes frontoposterior hyperextension of the head, due to frontal impact, concomitant with fractures or dislocations of upper spine. In the fourth mechanism, there is an absence of direct impact to the head, due to the indirect force of action after feet or buttocks­first impact. Most of these cases are accompanied by ring fractures as well. In situations such as these, the impact force is transmitted up the spinal column and upper vertebrae, and telescopically intruded into the skull, causing brainstem laceration. The jawbone and other facial bones can act as shock absorbers, and their fracture could diminish the energy transfer towards the skull and protect the brain and brainstem from injury. In all the cases with pontomedullary laceration posterior neck dissection should be performed during the autopsy, since upper spine injuries are often associated with this type of injury.

  8. Concomitant release of ventral tegmental acetylcholine and accumbal dopamine by ghrelin in rats.

    Directory of Open Access Journals (Sweden)

    Elisabet Jerlhag

    Full Text Available Ghrelin, an orexigenic peptide, regulates energy balance specifically via hypothalamic circuits. Growing evidence suggest that ghrelin increases the incentive value of motivated behaviours via activation of the cholinergic-dopaminergic reward link. It encompasses the cholinergic afferent projection from the laterodorsal tegmental area (LDTg to the dopaminergic cells of the ventral tegmental area (VTA and the mesolimbic dopamine system projecting from the VTA to nucleus accumbens (N.Acc.. Ghrelin receptors (GHS-R1A are expressed in these reward nodes and ghrelin administration into the LDTg increases accumbal dopamine, an effect involving nicotinic acetylcholine receptors in the VTA. The present series of experiments were undertaken directly to test this hypothesis. Here we show that ghrelin, administered peripherally or locally into the LDTg concomitantly increases ventral tegmental acetylcholine as well as accumbal dopamine release. A GHS-R1A antagonist blocks this synchronous neurotransmitter release induced by peripheral ghrelin. In addition, local perfusion of the unselective nicotinic antagonist mecamylamine into the VTA blocks the ability of ghrelin (administered into the LDTg to increase N.Acc.-dopamine, but not VTA-acetylcholine. Collectively our data indicate that ghrelin activates the LDTg causing a release of acetylcholine in the VTA, which in turn activates local nicotinic acetylcholine receptors causing a release of accumbal dopamine. Given that a dysfunction in the cholinergic-dopaminergic reward system is involved in addictive behaviours, including compulsive overeating and alcohol use disorder, and that hyperghrelinemia is associated with such addictive behaviours, ghrelin-responsive circuits may serve as a novel pharmacological target for treatment of alcohol use disorder as well as binge eating.

Usually, six to seven ports are employed for CAS, and spleen is removed by classical lateral approach or anterior approach. We report here our modified five-port and pedicle first approach for CAS in children to minimize the intraoperative bleeding and maximize the access. Materials and Methods : Twenty-one children underwent laparoscopic CAS with this new approach and their data were recorded prospectively. Following cholecystectomy (with ports 1-4, left side was elevated by 30°. The spleen was lifted by a grasper/fan retractor through port no. 5. The pedicle was dissected and splenic vessels were divided by ligasure (vessels < 8 mm, and for bulkier pedicle, vascular endo-GIA stapler was used. Short gastric and gastrosplenic ligament, lower pole and phrenico-colic attachments and upper pole attachments were dissected by ligasure in that sequence. Spleen was placed in endosac and delivered by digital fracture technique. Occasionally, lower transverse incision was made to deliver a massive spleen. Results : There were 12 males and 9 females with an average age of 8 years. Fourteen had sickle cell disease (SCD and 7 had SCD and beta thalassemia. All CAS were completed successfully without any complication. Total duration was 160 minutes. Cholecystectomy took an average of 35 minutes. Average blood loss was 140 ml. The mean splenic weight was 900 g and mean length was 20 cm. Duration of hospitalization was 3-4 days. Conclusion : CAS can be successfully performed by five ports. The pedicle first approach is extremely helpful in moderate to massive spleens as it reduces splenic size, vascularity and bleeding from capsular adhesions or inadvertant lacerations.

    Full Text Available Background. Vinorelbine (VRB and capecitabine (CAPE are demonstrated to be active in pretreated metastatic breast cancer patients. Different studies have demonstrated that the metronomic treatment is active with an acceptable toxicity profile. We designed a Phases I-II study to define the MTD of oral metronomic, VRB, and CAPE. Patients and Methods. Phase I: fixed dose of CAPE was 500 mg thrice a day, continuously. Level I of VRB was 20 mg/tot thrice a week for 3 weeks (1 cycle. Subsequent levels were 30 mg/tot and 40 mg/tot (Level III, respectively, if no Grades 3-4 toxicity were observed in the previous level. Phase II: further 32 patients received the MTD of VRB plus CAPE for a total of 187 cycles to confirm toxicity profile. Results. 12 patients were enrolled in Phase I and 22 in Phase II. Phase I: the MTD of VRB was 40 mg. Phase II: 187 cycles were delivered, observing 5.9% of Grades 3-4 toxicity. 31 patients are evaluable for efficacy, obtaining a clinical benefit rate of 58.1%. Conclusion. MTD of VRB with fixed dose of CAPE was 40 mg thrice a week and was the recommended dose for the ongoing Phase II multicenter study.

  14. HDR brachytherapy combined with interstitial hyperthermia in locally advanced cervical cancer patients initially treated with concomitant radiochemotherapy – a phase III study

    International Nuclear Information System (INIS)

    Background and purpose: The aim of this randomised trial was to investigate whether hyperthermia (HT) combined with interstitial brachytherapy (ISBT) has any influence on local control (LC), disease-free survival (DFS), or acute and late side effects in patients with advanced cervical cancer. Materials and methods: After radiochemotherapy, consecutive patients with cervical cancer (FIGO stage II–III) were randomly assigned to two treatment groups, either ISBT alone or ISBT combined with interstitial hyperthermia (ISHT). A total of 205 patients were included in the statistical analysis. Once a week, HT, at a temperature above 42.5 °C, was administered for 45 min before and during the HDR BT. Results: The median follow-up time was 45 months (range 3–72 months). An effect of hyperthermia was not detected for disease-free survival (DFS) (log-rank test: p = 0.178) or for local control (LC) (p = 0.991). According to Cox’s analysis, HT did not significantly influence failure or interactions with potential prognostic factors for LC or DFS. Statistical differences were not observed for the distribution of early and late complications between the HT and non HT groups. Conclusions: ISHT is well-tolerated and does not affect treatment-related early or late complications. Improvements in DFS and LC were not observed following the addition of ISHT to ISBT

    Background Select patients with peri-ampullary cancers require concomitant colon resection (CR) during a pancreaticoduodenectomy (PD) for margin-negative resections. This study analysed the impact of concomitant CR on major morbidity (MM) and mortality. Methods National Surgical Quality Improvement Program (NSQIP) patients undergoing PD for peri-ampullary cancers were identified from 2005 to 2012. A 4: 1 propensity-score matched analysis isolated the impact of CR upon PD. Risk factors for 30-day MM and mortality were analysed to determine post-operative sequelae of PD+CR. Results From 10 965 PD and 159 PD+CR patients, 624 and 156, respectively, were selected for 4: 1 matched analysis. PD+CR resulted in a higher MM and mortality (50.0% and 9.0%) versus PD alone (28.8% and 2.9%, respectively, P < 0.001). Multivariate analysis identified risk factors for MM after PD: concomitant CR [odds ratio (OR)–3.19, P < 0.001], smoking (OR–1.92, P = 0.005), a lack of functional independence (OR–3.29, P = 0.018), cardiac disease (OR–2.39, P = 0.011), decreased albumin (per g/dl, OR–1.38, P = 0.033) and a longer operative time (versus median time, OR–1.56, P = 0.029). Independent predictors of mortality included concomitant CR (OR–3.16, P = 0.010), ventilator dependence (OR–13.87, P < 0.001) and septic shock (OR–6.02, P < 0.001). Conclusions CR was an independent predictor of MM and mortality after a PD. Patients requiring PD+CR should be identified pre-operatively, maximally optimized and referred to experienced surgeons at expert centres. PMID:26223475

  19. Synchronous isolated splenic metastasis from colon carcinoma and concomitant splenic abscess: A case report and review of the literature

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    This study aimed to describe a case in which an isolated splenic metastasis was synchronous with the colonic primary and a concomitant splenic abscess was associated. A wide review of the literature was also performed. A.54-year-old woman with abdominal pain and fever was admitted to our department. Abdominal CT revealed two low-density areas in the spleen and wall-thickening of the left colonic flexure, which was indistinguishable from the spleen parenchyma. The patient underwent emergency celiotomy, with the presumptive diagnosis of obstructing colon carcinoma of the splenic flexure, and concomitant splenic abscess. Subtotal colectomy and splenectomy were performed. Pathological findings were consistent with mucinous colonic carcinoma, synchronous isolated splenic metastasis and concomitant splenic abscess.This paper is also a review of the existing literature on the association between colorectal cancer and splenic metastasis. Only 41 cases of isolated splenic metastasis from colon carcinoma have been reported in the literature. This report is the third described case of synchronous isolated splenic metastasis from colon carcinoma. Only one case with concomitant splenic abscess has been previously reported. When obstructing left-sided colorectal cancer is suspected, careful CT examination can allow early diagnosis of splenic involvement by the tumor. The literature review suggests that there might be a significant improvement in survival following splenectomy for a metachronous isolated splenic metastasis from colon carcinoma. Prognosis for synchronous splenic metastasis seems to be related to the advanced stage of the disease. Nevertheless, no definitive conclusions can be drawn because of the small number of cases.

  1. Concomitant predation on parasites is highly variable but constrains the ways in which parasites contribute to food web structure.

    Cirtwill, Alyssa R; Stouffer, Daniel B

    2015-05-01

    Previous analyses of empirical food webs (the networks of who eats whom in a community) have revealed that parasites exert a strong influence over observed food web structure and alter many network properties such as connectance and degree distributions. It remains unclear, however, whether these community-level effects are fully explained by differences in the ways that parasites and free-living species interact within a food web. To rigorously quantify the interrelationship between food web structure, the types of species in a web and the distinct types of feeding links between them, we introduce a shared methodology to quantify the structural roles of both species and feeding links. Roles are quantified based on the frequencies with which a species (or link) appears in different food web motifs - the building blocks of networks. We hypothesized that different types of species (e.g. top predators, basal resources, parasites) and different types of links between species (e.g. classic predation, parasitism, concomitant predation on parasites along with their hosts) will show characteristic differences in their food web roles. We found that parasites do indeed have unique structural roles in food webs. Moreover, we demonstrate that different types of feeding links (e.g. parasitism, predation or concomitant predation) are distributed differently in a food web context. More than any other interaction type, concomitant predation appears to constrain the roles of parasites. In contrast, concomitant predation links themselves have more variable roles than any other type of interaction. Together, our results provide a novel perspective on how both species and feeding link composition shape the structure of an ecological community and vice versa.

    Full Text Available Abstract Background Radiation induced optic neuropathy (RION is a rare but severe consequence of radiation therapy that is associated with adjuvant chemotherapy, specifically therapy with vincristine or nitrosoureas. However, there is very little evidence regarding the occurrence of RION after concomitant radiochemotherapy with temozolomide. Case Presentation The case of a 63 year old woman with glioblastoma multiforme and concomitant radiochemotherapy with temozolomide is described. Due to a slight depressive episode the patient also took hypericum perforatum. Five months after cessation of fractionated radiation and adjuvant chemotherapy with temozolomide (cumulative dose of 11040 mg the patient developed bilateral amaurosis due to RION. Tumor regrowth was excluded by magnetic resonance imaging. After the application of gadolinium a pathognomonic contrast enhancement of both prechiasmatic optic nerves could be observed. Conclusions In this patient, the occurrence of RION may have been the result of radiosensitization by temozolomide, which could have been strengthened by hypericin. Consequently, physicians should avoid a concomitant application of hypericum perforatum and radiochemotherapy.

    Full Text Available Abstract Background Coarctation of the aorta in the adulthood is sometimes associated with additional cardiovascular pathologies that require intervention. Ideal approach in such patients is uncertain. Anatomic left-sided short aortic bypass from the arcus aorta to descending aorta via median sternotomy allows simultaneuos repair of both complex aortic coarctation and concomitant cardiac operation. Materials Four adult patients were underwent Anatomic left-sided short aortic bypass operation for complex aortic coarctation through median sternotomy using deep hypothermic circulatory arrest. Concomitant cardiac operations were Bentall procedure for annuloaortic ectasia in one patient, coronary artery bypass grafting for three vessel disease in two patient, and patch closure of ventricular septal defect in one patient. Results All patients survived the operation and were alive with patent bypass at a mean follow-up of 36 months. No graft-related complications occurred, and there were no instances of stroke or paraplegia. Conclusion We conclude that single-stage repair of adult aortic coarctation with concomitant cardiovascular lesions can be performed safely using this newest technique.

    The diagnostic criteria of the third International Classification of Headache Disorders state that there should be no neurological deficits in patients with classical trigeminal neuralgia (TN) at clinical examination. However, studies demonstrating sensory abnormalities at bedside examination in TN patients have questioned this. Our aim was to examine whether TN patients without sensory abnormalities at neurological examination have sensory abnormalities at quantitative sensory testing (QST) and whether there were any QST differences between TN with and without concomitant persistent pain. Thirty-six TN patients were investigated with the standardized QST protocol by the German Research Network on Neuropathic Pain. The investigators were blinded to presence of concomitant persistent pain and symptomatic side. Based on comparison to the German Research Network on Neuropathic Pain controls, z scores were calculated to process frequency analyses and Z-profiles. We found increased mechanical detection threshold on the symptomatic side (47.2% vs 0%, P = 0.008), asymptomatic side (33.3% vs 0%, P = 0.011), and hand (36% vs 0%, P Trigeminal neuralgia patients with concomitant persistent pain tended to have higher mean z score values compared to TN with purely paroxysmal pain indicative of decreased detection thresholds. Trigeminal neuralgia patients with no sensory abnormalities at neurological examination had generalized subclinical hypoesthesia, which was more pronounced on the symptomatic side, and thermal and mechanical hyperalgesia. This could indicate pain-induced hypoesthesia and sensitization induced by central mechanisms. PMID:26894914

    During the past decade, the southern regions of the U.S. have experienced rapid change which is expected to continue into the foreseeable future. Growth in population, industry, and resource development has been attributed to a variety of advantages such as an abundant and inexpensive labor force, a mild climate, and the availability of energy, water, land, and other natural resources. While this growth has many benefits for the region, it also creates the potential for increased air, water, and solid waste pollution, and modification of natural habitats. A workshop was convened to consider the Mobile Bay area as a site-specific case of growth and its environmental consequences in the southern region. The objectives of the modeling workshop were to: (1) identify major factors of economic development as they relate to growth in the area over the immediate and longer term; (2) identify major environmental and resource management issues associated with this expected growth; and (3) identify and characterize the complex interrelationships among economic and environmental factors. This report summarizes the activities and results of a modeling workshop concerning economic growth and concomitant resource management issues in the Mobile Bay area. The workshop was organized around construction of a simulation model representing the relationships between a series of actions and indicators identified by participants. The workshop model had five major components. An Industry Submodel generated scenarios of growth in several industrial and transportation sectors. A Human Population/Economy Submodel calculated human population and economic variables in response to employment opportunities. A Land Use/Air Quality Submodel tabulated changes in land use, shoreline use, and air quality. A Water Submodel calculated indicators of water quality and quantity for fresh surface water, ground water, and Mobile Bay based on discharge information provided by the Industry and Human

    .02%, femoral (0.18% vs. 0.09%, renal (0.62% vs. 0.25%, and tibialis (0.16% vs. 0.06% arteries had a higher incidence of stenosis than those in the non-diabetics. Conclusion: We conclude that in diabetic patients with concomitant CAD, special attention must be directed towards the diagnosis of PVD using physical examination, Doppler sonography; and where needed, CT-angiography or invasive angiography. Also, in risk assessment, the presence of PVD should be strongly considered for CAD patients.

    Background: In patients with loco-regionally advanced head and neck cancer conventionally fractionated radiotherapy alone results in poor loco-regional control and survival rates. Treatment intensification by simultaneous administration of cytotoxic drugs produces higher acute morbidity. Therefore chemical radioprotection of normal tissues may be of clinical benefit. Patients and Methods: In a pilot study patients with advanced nonresectable head neck cancer treated with conventionally fractionated radical radiotherapy (60 to 66 Gy total doses) and concomitantly given 5-fluorouracil as protracted venous infusion, 250 mg/sqm/24 h over the entire treatment period were given amifostine 300 mg absolutely before each fraction. Acute treatment related mobidity was scored according to CTC classification and loco-regional control and survival rates were estimated. Comparison was made with a historical control group of identical chemoradiation but without amifostine application. Results: Chemoradiation induced oral mucositis was delayed and showed significant lower degrees at all 10 Gy increments (p<0.05) except 60 Gy and over (p>0.05). No significant toxicity was recorded with respect to blood pressure, serum calcium, potassium, hematologic parameters, emesis, nausea or body weight loss. Progression free survival and overall survival probability at 2 years were not statistically different in both cohorts. Conclusion: Amifostine given before each fraction of radiotherapy over 6 weeks has no cumulative toxicity, was well tolerated and may reduce treatment induced oral mucositis. No tumor protective effect was observed. (orig.)

    Evaluating prospective protein pharmaceutical stability from accelerated screening is a critical challenge in biotherapeutic discovery and development. Measurements of protein unfolding transitions are widely employed for comparing candidate molecules and formulations; however, the interrelationships between intrinsic protein conformational stability and pharmaceutical robustness are complex and thermal unfolding measurements can be misleading. Beyond the discovery phase of drug development, astute formulation design is one of the most crucial factors enabling the protein to resist damage to its higher order structure-initially from bioprocessing stresses, then from stresses encountered during its journey from the product manufacturing site to the bloodstream of the patient. Therapeutic monoclonal antibodies are multidomain proteins that represent a large and growing segment of the biotechnology pipeline. In this chapter, we describe how differential scanning calorimetry may be leveraged synergistically with isothermal chemical denaturation and intrinsic fluorescence with concomitant static light scattering to elucidate characteristics of mAb unfolding and aggregation that are helpful toward understanding and designing optimal pharmaceutical compositions for these molecules.

  11. Mouse hepatitis coronavirus replication induces host translational shutoff and mRNA decay, with concomitant formation of stress granules and processing bodies.

    Many viruses, including coronaviruses, induce host translational shutoff, while maintaining synthesis of their own gene products. In this study we performed genome-wide microarray analyses of the expression patterns of mouse hepatitis coronavirus (MHV)-infected cells. At the time of MHV-induced host translational shutoff, downregulation of numerous mRNAs, many of which encode protein translation-related factors, was observed. This downregulation, which is reminiscent of a cellular stress response, was dependent on viral replication and caused by mRNA decay. Concomitantly, phosphorylation of the eukaryotic translation initiation factor 2alpha was increased in MHV-infected cells. In addition, stress granules and processing bodies appeared, which are sites for mRNA stalling and degradation respectively. We propose that MHV replication induces host translational shutoff by triggering an integrated stress response. However, MHV replication per se does not appear to benefit from the inhibition of host protein synthesis, at least in vitro, since viral replication was not negatively affected but rather enhanced in cells with impaired translational shutoff.

    A 38-year-old woman was admitted to our hospital because of amenorrhea, multiple bone fractures, and a Cushingoid appearance. Endocrinological investigations revealed that she had co-existing Cushing's disease and prolactinoma, with a serum level of prolactin (PRL) at 1,480 ng/mL, corticotropin (ACTH) at 81.3 pg/mL, and cortisol at 16.6 μg/dL. Due to the lack of indication for transsphenoidal surgery, cabergoline monotherapy was initiated. A 6-month course of treatment resulted in only subtle amelioration of hypercortisolism, while hyperprolactinemia was dramatically improved. In 5 cases of bihormonal (ACTH/PRL) pituitary macroadenoma reported in the English literature, 2 were initially treated with dopaminergic agonists with substantial effectiveness for both PRL and ACTH. We herein report an extremely rare case of bihormonal macroadenoma in which only PRL was responsive to treatment. PMID:27086808

    Ethanol abuse is linked to several acute and chronic injuries that can lead to health problems. Ethanol addiction is one of the most severe diseases linked to the abuse of this drug. Symptoms of ethanol addiction include compulsive substance intake and withdrawal syndrome. Stress exposure has an important role in addictive behavior for many drugs of abuse (including ethanol), but the consequences of stress and ethanol in the organism when these factors are concomitant results in a complex interaction. We investigated the effects of concomitant, chronic administration of ethanol and stress exposure on the withdrawal and consumption of, as well as the preference for, ethanol in mice. Male Swiss mice (30-35 g, 8-10 per group) were exposed to an ethanol liquid diet as the only source of food for 15 days. In the final 5 days, they were exposed to forced swimming stress. Twelve hours after removal of the ethanol liquid diet, animals were evaluated for ethanol withdrawal by measuring anxiety-related behaviors and locomotor activity. Twenty-four hours after evaluation of ethanol withdrawal, they were evaluated for voluntary consumption of ethanol in a "three-bottle choice" paradigm. Mice exposed to chronic consumption of ethanol had decreased locomotor activity during withdrawal. Contrary to our expectations, a concomitant forced swimming stress did not aggravate ethanol withdrawal. Nevertheless, simultaneous ethanol administration and stress exposure increased voluntary consumption of ethanol, mainly solutions containing high concentrations of ethanol. These results showed that stressful situations during ethanol intake may aggravate specific addiction-related behaviors.

    Full Text Available OBJECTIVE: To present our experience of combining transperitoneal mini-laparoscopic pyeloplasty (mini-LP and concomitant ureteroscopy-assisted pyelolithotomy (U-P for ureteropelvic junction obstruction (UPJO complicated by renal caliceal stones in the same session. METHODS: Between May 2007 and December 2011, mini-LP and concomitant U-P was performed in nine patients with UPJO and ipsilateral renal caliceal stones. Stone location and burden were preoperatively assessed. After pyelotomy with appropriate length (about 4 mm, a 16-Fr catheter sheath replaced the uppermost or lowermost laparoscopic trocar and was introduced directly into the renal pelvis under the guidance of a guide wire and laparoscopic vision. A 7.5F rigid ureteroscopy passed through the catheter sheath into the plevis. Intracorporeal lithotripsy and/or pressure irrigation via a pump was used for caliceal stone removal. Subsequently, laparoscopic pyeloplasty was performed in a standard fashion. Postoperative imaging was assessed. RESULTS: The calculi sizes ranged from 2 to 11 mm (mean, 7.1 mm and an average of 3 stones per patient was removed (range, 1 to 6 stones. Complete stone clearance confirmed by postoperative imaging was achieved in all patients. Mean operative time was 210 minutes, and estimated blood loss was 20 mL. Mean hospital stay was 5 days (4-7. Stent was removed after 4-8 weeks. No intraoperative or postoperative complications were noted during a mean follow-up of 18.5 months (range, 6 to 24 months. CONCLUSIONS: Mini-LP and concomitant U-P are simple and effective alternatives for the simultaneous management of UPJO complicated by coexisting ipsilateral renal caliceal stones.

    Given the high costs of conducting a drug-response trial, researchers are now aiming to use retrospective analyses to conduct genome-wide association studies (GWAS) to identify underlying genetic contributions to drug-response variation. To prevent confounding results from a GWAS to investigate drug response, it is necessary to account for concomitant medications, defined as any medication taken concurrently with the primary medication being investigated. We use data from the Action to Control Cardiovascular Disease (ACCORD) trial in order to implement a novel scoring procedure for incorporating concomitant medication information into a linear regression model in preparation for GWAS. In order to accomplish this, two primary medications were selected: thiazolidinediones and metformin because of the wide-spread use of these medications and large sample sizes available within the ACCORD trial. A third medication, fenofibrate, along with a known confounding medication, statin, were chosen as a proof-of-principle for the scoring procedure. Previous studies have identified SNP rs7412 as being associated with statin response. Here we hypothesize that including the score for statin as a covariate in the GWAS model will correct for confounding of statin and yield a change in association at rs7412. The response of the confounded signal was successfully diminished from p = 3.19 × 10−7 to p = 1.76 × 10−5, by accounting for statin using the scoring procedure presented here. This approach provides the ability for researchers to account for concomitant medications in complex trial designs where monotherapy treatment regimens are not available.

    The objective of this study was to compare results of dynamic magnetotherapy (DMT), transdermal electroneurostimulation (TDENS), and traditional ultrahigh frequency (UHF) therapy in 473 patients with mandibular fractures and concomitant inflammatory diseases of paradontium. The parameters measured in the study included hygienic and paradontal indices, microcirculation patterns (using laser Doppler flowmetry), and the degree of mandibular fragment consolidation. It was shown that combined treatment with DMT and TDENS using an AMO-ATOS-E apparatus permits to eliminate clinical symptoms of paradontal inflammatory diseases twice as fast as traditional ultrahigh frequency therapy and ensures a two-fold reduction in the frequency of complications.

    Full Text Available Behcet’s disease is a rare immune mediated systemic vasculitis which besides it’s more frequent involvement of eyes and skin,   sometimes present with aortic pseudo aneurysm and more rarely cardiac inflammatory masses.A 51-year-old patient with Behçet’s Disease presented with two symptomatic aortic pseudoaneurysms concomitant with a right atrial mass. Computed tomography (CT revealed one supra-celiac and another infrarenal aortic pseudoaneurysms. Echocardiography showed a large mobile mass in the right atrium. Both pseudoaneurysms were successfully excluded simultaneously via endovascular approach with Zenith stent-grafts, and the atrial mass was surgically removed 10 days later. Post-implant CT showed successful exclusion of both pseudo-aneurysms, patency of all relevant arteries, and patient is now asymptomatic and has returned to normal lifestyle. Multiple pseudoaneurysms concomitant with a right atrial mass can be an initial manifestation of Behçet’s disease. Endovascular repair can be a good treatment option for the pseudoaneurysms.

  5. Forecast evaluation of the impact of the concomitant chemoradiotherapy after conservative breast treatment on the esthetic satisfaction: difference between physician and patient assessment

    International Nuclear Information System (INIS)

    After conservative surgery of mammary glands, the concomitant chemoradiotherapy leads a significant increase of delayed effects ( stage over or equal to 2). The esthetic result is also subjective. The patients satisfaction is superior to the physician's ones after conservative treatment of mammary glands and is not only determined by delayed toxicity. Several methods of evaluation allow to find an esthetic result more harmful after concomitant chemoradiotherapy. (N.C.)

    Objective To systematically evaluate the clinical effect and safety of capecitabine plus docetaxel in the treatment of the pa-tients with anthracycline-failed metastatic breast cancer. Methods The English databases of Medline, Embase, Pubmed, Cochrane library and the Chinese databases of CNKI, VIP, Wanfang were retrieved by computer. The randomized controlled trials ( RCTs ) on the combina-tion therapy of capecitabine plus docetaxel in the anthracycline-failed patients with metastatic breast cancer were included. The retrieval cut-off date was up to December 2013. The retrieval was limited to English and Chinese languages. The methodological quality of the included RCTs was evaluated by the Cochrane system evaluation method. After extracting the effective data, the RevMan 5. 0 software was applied for conducting the meta-analysis on the objective response rate ( ORR ) , stable disease ( SD ) , time to progression ( TTP ) and adverse events. Results 4 RCTs involving 419 patients were included. The meta-analysis results showed that capecitabine plus docetaxel and epirubicin plus docetaxel for treating anthracycline-failed metastatic breast cancer had no obvious differences in ORR [ RR=1. 17, 95% CI(0. 98, 1. 39),P=0. 08], SD[ RR=0. 79,95% CI(0. 58,1. 08),P=0. 14] and TTP[ RR=1. 11,95% CI(0. 92, 1. 33),P<0. 28], indicating that the efficacy of the two regimens was similar. The meta-analysis showed that the adverse reactions of capecitabine were hand-foot syndrome, anemia, nausea, vomiting as well as myalgia with statistical significance ( P<0. 01 );in which the RR value revealed that the occurrence rate of the hand-foot syndrome in the capecitabine group was greater than that in the non-capecitabine group, but the RR< 1 in anemia, vomiting, nausea and myalgia, which revealing that their occurrence rates in the epirubicin group were greater;other adverse reactions had no statistical significance. Conclusion Capecitabine plus docetaxel and epirubicin plus docetaxel have

    Administration of fluvoxamine with concomitant benzodiazepines is common in clinical situations. This study investigated the effects of the coadministration of fluvoxamine on plasma concentrations of etizolam and evaluated the effects of various fluvoxamine doses on drug interactions with etizolam. Subjects were 18 Japanese outpatients concomitantly treated with fluvoxamine before or after monotherapy with etizolam. Plasma concentrations of etizolam were measured using a column-switching high-performance liquid chromatographic method with ultraviolet detection. In 17 subjects treated concomitantly with fluvoxamine at 25 mg or 50 mg, the ranges of plasma concentrations of etizolam corrected for the dose increased from 2.0-13.3 (mean 6.3 +/- 3.6, n = 17) in monotherapy to 2.7-18.2 (mean 9.6 +/- 5.1, n = 17) ng/mL/mg in concomitant doses. Wide variations were observed in the drug interactions; however, coadministration with fluvoxamine produced significant changes in the plasma concentrations of etizolam (P etizolam-monotherapy and the fluvoxamine-concomitant states. Of the 12 subjects treated concomitantly with fluvoxamine at 25 mg, 2 subjects received fluvoxamine at a dose increased up to 150 mg, and another received fluvoxamine at a dose increased up to 200 mg. They showed an increase in the plasma concentrations of etizolam in a fluvoxamine dose-dependent manner; more particularly, the increased dose of fluvoxamine (150 mg and 200 mg) resulted in about a twofold variation in plasma concentrations of etizolam.

    Full Text Available Abstract Background Brain metastases (BM represent one of the most frequent complications related to cancer, and their treatment continues to evolve. We have evaluated the activity, toxicity and the impact on Quality of Life (QoL of a concomitant treatment with whole brain radiotherapy (WBRT and Temozolomide (TMZ in patients with brain metastases from solid tumors in a prospective Simon two stage study. Methods Fifty-nine patients were enrolled and received 30 Gy WBRT with concomitant TMZ (75 mg/m2/day for ten days, and subsequently TMZ (150 mg/m2/day for up to six cycles. The primary end points were clinical symptoms and radiologic response. Results Five patients had a complete response, 21 patients had a partial response, while 18 patients had stable disease. The overall response rate (45% exceeded the target activity per study design. The median time to progression was 9 months. Median overall survival was 13 months. The most frequent toxicities included grade 3 neutropenia (15% and anemia (13%, and only one patient developed a grade 4 thrombocytopenia. Age, Karnofsky performance status, presence of extracranial metastases and the recursive partitioning analysis (RPA were found to be predictive factors for response in patients. Overall survival (OS and progression-free survival (PFS were dependent on age and on the RPA class. Conclusion We conclude that this treatment is well tolerated, with an encouraging objective response rate, and a significant improvement in quality of life (p

    Background The aims of this study were to investigate the clinical characteristics of patients with combined anterior instability and superior labrum from anterior to posterior (SLAP) lesions, and to analyze the effect of concomitant SLAP repair on surgical outcomes. Methods We retrospectively reviewed patients who underwent arthroscopic stabilization for anterior shoulder instability between January 2004 and March 2013. A total of 120 patients were available for at least 1-year follow-up. Forty-four patients with reparable concomitant detached SLAP lesions (group I) underwent combined SLAP and anterior stabilization, and 76 patients without SLAP lesions (group II) underwent anterior stabilization alone. Patient characteristics, preoperative and postoperative pain scores, Rowe scores, and shoulder ranges of motion were compared between the 2 groups. Results Patients in group I had higher incidences of high-energy trauma (p = 0.03), worse preoperative pain visual analogue scale (VAS) (p = 0.02), and Rowe scores (p = 0.04). The postoperative pain VAS and Rowe scores improved equally in both groups without significant differences. Limitation in postoperative range of motion was similar between the groups (all p-value > 0.05). Conclusions Anterior instability with SLAP lesion may not be related to frequent episodes of dislocation but rather to a high-energy trauma. SLAP fixation with anterior stabilization procedures did not lead to poor functional outcomes if appropriate surgical techniques were followed. PMID:27247742

    Endogenous secretory receptor (esRAGE) for advanced glycation end-product (AGE) acts as decoy for AGEs. The AGE-to-esRAGE ratio was hypothesized to be implicated in diabetic vasculopathy. We investigated an association of esRAGE and methylglyoxal-adducts serum level, as well as AGE-to-esRAGE ratio in subpopulation of diabetic patients with or without concomitant hyperlipidemia and macrovascular disease in history. In diabetes with concomitant hyperlipidemia esRAGE was significantly decreased compared to hyperlipidemia with normal glucose metabolism (0.306+/-0.2 vs. 0.367+/-0.1; p=0.019) or diabetes alone (0.306+/-0.2 vs. 0.404+/-0.1; p=0.004). High AGE/esRAGE ratio, found in diabetic patients with hyperlipidemia, pointed to increased production of AGEs and low expression of esRAGE. In multivariable analysis adjusted for several confounding factors, increased AGE/esRAGE ratio was recognized as a high risk for vascular disease outcomes.

    End-stage degenerative joint disease of the ankle and concomitant ipsilateral Stage II posterior tibial tendon insufficient flat foot is a well known entity. Despite this, treatment options have not been discussed in the orthopaedic literature. A case series consisting of five patients was conducted to determine the efficacy of our treatment proposal. Our surgical treatment included an ankle fusion and concomitant flat foot reconstruction with a medializing calcaneal osteotomy, lengthening calcaneal osteotomy, and flexor digitorum longus transfer. At the final followup visit all patients were content with the results of the procedure, and would have it performed again. Each patient had significant relief of ankle and foot pain, and believed they had improved quality of life and function. Complications included two ankle nonunions treated with revision bone grafting and internal fixation, painful hardware and iliac crest hematoma. We conclude that our method of treatment is a viable option for this complex problem. A long recovery period should be anticipated and patients should be counseled accordingly. PMID:22381416

    Concomitant traumatic brain injury (TBI) and long bone fracture are commonly observed in multitrauma and polytrauma. Despite clinical observations of enhanced bone healing in patients with TBI, the relationship between TBI and fracture healing remains poorly understood, with clinical data limited by the presence of several confounding variables. Here we developed a novel trauma model featuring closed-skull weight-drop TBI and concomitant tibial fracture in order to investigate the effect of TBI on fracture healing. Male mice were assigned into Fracture + Sham TBI (FX) or Fracture + TBI (MULTI) groups and sacrificed at 21 and 35 days post-injury for analysis of healing fractures by micro computed tomography (μCT) and histomorphometry. μCT analysis revealed calluses from MULTI mice had a greater bone and total tissue volume, and displayed higher mean polar moment of inertia when compared to calluses from FX mice at 21 days post-injury. Histomorphometric results demonstrated an increased amount of trabecular bone in MULTI calluses at 21 days post-injury. These findings indicate that closed head TBI results in calluses that are larger in size and have an increased bone volume, which is consistent with the notion that TBI induces the formation of a more robust callus.

    Objective To analyze the clinical efficacy and safety of capecitabine combined with autologous cytokine-induced killer cells ( CIK) maintenance therapy in treatment of metastatic triple negative breast cancer ( MTNBC) . Methods The MTNBC patients undergoing capecitabine-based chemotherapy as first line treatment, whose therapeutic effect was SD or above were selected and divided into treatment group and control group randomly. The treatment group received capecitabine maintenance therapy with autologous CIK after the first line treatment. The control group underwent only capecitabine mainte-nance therapy. Baseline assessment was taken 15 d after the end of the last cycle of chemotherapy. The patients were followed up once every two cycles. The median follow-up time was 11. 2 months. T lymphocyte subpopulation in peripheral blood was measured, the side effects, PFS and OS of both groups were observed. Results CD3+CD8+CTL and CD4+CD25+Treg of treatment group were compared at the time of baseline assessment and 1 month after three cycles of chemotherapy. There was no statistically significant difference (P>0. 05). CD3+T, CD3+CD4+Th, CD3+CD56+CIK showed significant im-provement, compared with that before treatment (P0. 05). Conclusion Maintenance therapy of Capecitabine combined with autologous CIK cells in treatment of MTNBC after first-line treatment improves the immune function to enhance the ability of antitumor by natural immunity, which can prolong PFS, and is safe as well. In short, it can improve the therapeutic effect of maintenance therapy in patients with MTNBC.%目的 探讨自体细胞因子诱导杀伤细胞( CIK)免疫治疗联合卡培他滨治疗复发转移性三阴性乳腺癌( metastatic triple negative breast cancer, MTNBC)的临床效果和安全性. 方法 选取一线应用卡培他滨化疗后效果评价病情稳定( SD)或以上的MTNBC患者,随机分为治疗组和对照组. 两组均应用卡培他滨维持化疗,治疗组在此

    Full Text Available Background: Thrombolysis is the only approved therapy for acute stroke. However, life-threatening complications such as intracerebral hemorrhage (ICH can develop after intravenous administration of tissue plasminogen activator (tPA. Both infection and thrombolysis during cerebral ischemia disrupt the blood-brain barrier (BBB. tPA can induce matrix metalloproteinase-9 (MMP-9, which is known to be involved in BBB disruption. However, it has still not been investigated whether preexisting influenza virus infection during thrombolysis after acute stroke affects systemic levels of MMP-9 and its inhibitor TIMP-1 and whether increased systemic MMP-9 levels affect ICH. This study aimed to investigate the influence of influenza virus infection on plasma levels of MMP-9 and TIMP-1 after thrombolysis in acute stroke, and to determine whether the infection correlates with intracerebral bleeding. Methods: C57BL/6 mice were infected by administering 1 × 105 plaque-forming units of human influenza (H1N1 virus intranasally. After 3 days of infection the middle cerebral artery was occluded for 45 min and then reperfused. Intravenous tPA (10 mg/kg treatment was started 10 min after stroke onset. Twenty-four hours after stroke onset, mice were deeply anesthetized with ketamine, venous blood was drawn from the caval vein and centrifuged at 2,000 rpm, and the supernatant was collected and frozen at -80°C. Plasma levels of MMP-9 and TIMP-1 were quantified by using ELISA. Results: After stroke, plasma MMP-9 was significantly increased in mice with a concomitant influenza infection that were treated with tPA (9.99 ± 0.62 ng/ml, n = 7 as compared to noninfected control mice that were treated with tPA (4.74 ± 0.48 ng/ml, n = 8. Moreover, plasma levels of TIMP-1, an inhibitor of MMP-9, were also significantly increased in mice treated with tPA after concomitant infection and stroke (42.17 ± 7.02 ng/ml, n = 7 as compared to noninfected control mice that were treated

    Full Text Available The Eosinophilic Granulomatosis with Polyangiitis (formerly Churg- Strauss Syndrome (EGPA is a systemic inflammatory disease characterized by the presence of rhinitis, asthma, peripheral eosinophilia, and vasculitis—the latter being characteristic of the late stage of the disease. After several years from the onset of the disease, small- and medium-sized vessel vasculitis ensues, undertaking various organs and systems. Upper and lower airways, skin, nervous system, gastrointestinal tract, heart, and kidneys are the most commonly involved organs. It is believed that tissue injury is the result of processes mediated by antineutrophil cytoplasmic antibody (ANCA, or toxic mediators released by eosinophils. Although it is classified as ANCA-associated vasculitis, these autoantibodies are present in only 40% of cases. The authors report the case of a patient with EGPA, who had a history of asthma, peripheral and central neuropathy, palpable purpura, gastrointestinal micro perforation, peripheral eosinophilia, and the presence of myeloperoxidase-antineutrophil cytoplasmic antibody. Inflammatory parameters improved after the initiation of treatment, but 1 month after hospital discharge the patient developed symptoms compatible with pulmonary embolism and died. Thrombophilia that occurs in EGPA is due to the interaction between the inflammatory response and eosinophilia with the clotting system resulting in a pro-thrombotic state. Although not yet well-determined, the authors call attention to the possibility of the impact of thromboembolic events on the prognosis of patients with EGPA. In addition to the adequate immunosuppressive treatment, prophylaxis and treatment for thrombosis should never be overlooked.

    Full Text Available We report a case of a 13-year-old girl with chronic recurrent multifocal osteomyelitis (CRMO who developed severe arthritis in four different joints within the first year from the onset of the disease. Her multiple vertebrae lesions showed significant amelioration after a 2-month treatment with prednisolone. In parallel, the initial severe symmetrical arthritis of both knees showing overt synovitis and joint effusion, in the absence of lesions in the metaphyses of the femur or the tibia, responded remarkably well in intra-articular triamcinolone hexacetonide injections. However, upon discontinuation of prednisolone, the patient developed severe arthritis of her right ankle and the proximal interphalangeal joint of her right middle finger. Thus, prednisolone was reinitiated combined with methotrexate, and the patient went into remission, which persists one year after prednisolone tapering. The appearance of arthritis in both knees in the absence of bone lesions and the emergence of severe arthritis of the ankle after remission of spinal bone lesions suggest that CRMO and juvenile idiopathic arthritis may coexist and be causally related.

  20. Concomitant multiple myeloma spectrum diagnosis in a central retinal vein occlusion: a case report and review.

    2016-07-01

    Multiple myeloma is a neoplastic plasma-cell disorder resulting from malignant plasma cells in the bone marrow. It can cause a hyperviscosity syndrome secondary to the paraproteinaemia associated with the disease. The increased hyperviscosity can lead to retinal vein occlusions and other ocular problems that may challenge clinicians. In patients with multiple myeloma and hypertension and/or diabetes mellitus, retinal changes appear similar and changes due to one disease or the other may be difficult to determine. A 48-year-old white female presented to the clinic with a complaint of blurry vision in her left eye. A full comprehensive ocular examination revealed a central retinal vein occlusion presumably from the patient's history of hypertension, diabetes mellitus and hypercholesterolaemia. Further bloodwork revealed monoclonal protein in the patient's serum and an increased percentage of plasma cells in the bone marrow. She was diagnosed with monoclonal gammopathy of undetermined significance, part of the multiple myeloma disease spectrum. She was referred to a retinal specialist for initiation of intravitreal injections of anti-vascular endothelial growth factor. Multiple myeloma has been implicated in younger patients as an underlying cause of retinal vein occlusions. Multiple myeloma should be considered as a differential diagnosis in young patients with retinal vein occlusions, even if other risk factors for venous occlusion like hypertension, diabetes mellitus and hypercholesterolaemia are present. Timely referral to the patient's primary care physician and haematologist is important for appropriate treatment and control of underlying systemic conditions. PMID:27079282

  1. Salinomycin induces autophagy in colon and breast cancer cells with concomitant generation of reactive oxygen species.

    Berlinda Verdoodt

    Full Text Available BACKGROUND: Salinomycin is a polyether ionophore antibiotic that has recently been shown to induce cell death in human cancer cells displaying multiple mechanisms of drug resistance. The underlying mechanisms leading to cell death after salinomycin treatment have not been well characterized. We therefore investigated the role of salinomycin in caspase dependent and independent cell death in colon cancer (SW480, SW620, RKO and breast cancer cell lines (MCF-7, T47D, MDA-MB-453. METHODOLOGY/PRINCIPAL FINDINGS: We detected features of apoptosis in all cell lines tested, but the executor caspases 3 and 7 were only strongly activated in RKO and MDA-MB-453 cells. MCF-7 and SW620 cells instead presented features of autophagy such as cytoplasmic vacuolization and LC3 processing. Caspase proficient cell lines activated autophagy at lower salinomycin concentrations and before the onset of caspase activation. Salinomycin also led to the formation of reactive oxygen species (ROS eliciting JNK activation and induction of the transcription factor JUN. Salinomycin mediated cell death could be partially inhibited by the free radical scavenger N-acetyl-cysteine, implicating ROS formation in the mechanism of salinomycin toxicity. CONCLUSIONS: Our data indicate that, in addition to its previously reported induction of caspase dependent apoptosis, the initiation of autophagy is an important and early effect of salinomycin in tumor cells.

  2. Neochloris oleoabundans grown on anaerobically digested dairy manure for concomitant nutrient removal and biodiesel feedstock production

    International Nuclear Information System (INIS)

    Microalgae have been investigated as a promising biodiesel feedstock; however, large-scale production is not currently cost-competitive with petroleum diesel, and its environmental impacts have received little attention. Using wastewater to supply nutrients for algal growth obviates synthetic fertilizer use, provides on-site nutrient removal, and reduces greenhouse gas emissions. In this work, anaerobically digested dairy manure was used to grow the oleaginous green alga Neochloris oleoabundans. In batch culture experiments with both synthetic media and anaerobic digester effluent, N. oleoabundans assimilated 90-95% of the initial nitrate and ammonium after 6 d and yielded 10-30% fatty acid methyl esters on a dry weight basis. Cellular lipid content and the N concentration in the growth media were inversely correlated. In addition, the proportion of polyunsaturated fatty acids (i.e. C16:3, C18:2, and C18:3) decreased with N concentration over time while the proportion of C18:1 fatty acid increased. Although N deficiency is likely the primary driver behind lipid accumulation, the influence of culture pH confounded results and requires further study. Other living microorganisms in the digester effluent were not observed to affect algal growth and lipid productivity, though the breakdown of organic nitrogen may have hindered lipid accumulation traditionally achieved through the manipulation of synthetic media. This work highlights the potential for waste-grown mono-algal cultures to produce high quality biodiesel while accomplishing simultaneous wastewater treatment.

    Mexico serves as a global model for advances in rabies prevention and control in dogs. The Mexican Ministry of Health (MMH) annual application of approximately 16 million doses of parenteral rabies vaccine has resulted in significant reductions in canine rabies during the past 20 years. One collateral parameter of rabies programs is dog population management. Enhanced public awareness is critical to reinforce responsible pet ownership. Surgical spaying and neutering remain important to prevent reproduction, but are impractical for achieving dog population management goals. GonaCon™, an anti-gonadotropin releasing hormone (GnRH) vaccine, was initially tested in captive female dogs on the Navajo Nation, 2008. The MMH led this international collaborative study on an improved formulation of GonaCon™ in captive dogs with local representatives in Hidalgo, Mexico in 2011. This study contained 20 bitches assigned to Group A (6 control), Group B (7 GonaCon™), and Group C (7 GonaCon™ and rabies vaccine). Vaccines were delivered IM. Animals were placed under observation and evaluated during the 61-day trial. Clinically, all dogs behaved normally. No limping or prostration was observed, in spite of minor muscle atrophy post-mortem in the left hind leg of dogs that received GonaCon™. Two dogs that began the study pregnant give birth to healthy pups. Dogs that received a GonaCon™ injection had macro and microscopic lesions consistent with prior findings, but the adverse injection effects were less frequent and lower in intensity. Both vaccines were immunogenic based on significant increases in rabies virus neutralizing antibodies and anti-GnRH antibodies in treatment Groups B and C. Simultaneous administration of GonaCon™ and rabies vaccine in Group C did not affect immunogenicity. Progesterone was suppressed significantly in comparison to controls. Future studies that monitor fertility through multiple breeding cycles represent a research need to determine the

    Full Text Available Abstract Background Patients with HER2-overexpressing metastatic breast cancer, despite initially benefiting from the monoclonal antibody trastuzumab and the EGFR/HER2 tyrosine kinase inhibitor lapatinib, will eventually have progressive disease. HER2-based vaccines induce polyclonal antibody responses against HER2 that demonstrate enhanced anti-tumor activity when combined with lapatinib in murine models. We wished to test the clinical safety, immunogenicity, and activity of a HER2-based cancer vaccine, when combined with lapatinib. Methods We immunized women (n = 12 with metastatic, trastuzumab-refractory, HER2-overexpressing breast cancer with dHER2, a recombinant protein consisting of extracellular domain (ECD and a portion of the intracellular domain (ICD of HER2 combined with the adjuvant AS15, containing MPL, QS21, CpG and liposome. Lapatinib (1250 mg/day was administered concurrently. Peripheral blood antibody and T cell responses were measured. Results This regimen was well tolerated, with no cardiotoxicity. Anti-HER2-specific antibody was induced in all patients whereas HER2-specific T cells were detected in one patient. Preliminary analyses of patient serum demonstrated downstream signaling inhibition in HER2 expressing tumor cells. The median time to progression was 55 days, with the majority of patients progressing prior to induction of peak anti-HER2 immune responses; however, 300-day overall survival was 92% (95% CI: 77-100%. Conclusions dHER2 combined with lapatinib was safe and immunogenic with promising long term survival in those with HER2-overexpressing breast cancers refractory to trastuzumab. Further studies to define the anticancer activity of the antibodies induced by HER2 vaccines along with lapatinib are underway. Trial registry ClinicalTrials.gov NCT00952692

    The incidence of Sjögren syndrome (SS) in primary biliary cirrhosis (PBC) patients is high. The influence of SS on the clinical outcomes of PBC patients, however, remains unclear. Our study retrospectively collected data on PBC-only patients and PBC patients with concomitant SS (PBC-SS) to compare the clinical differences of long-term outcomes between them.A total of 183 patients were diagnosed with PBC from January 1999 to December 2014 at our hospital. Of these, the authors excluded patients with diabetes, hypertension, advanced liver cirrhosis at initial diagnosis of PBC (Child-Turcotte-Pugh classification score of ≥7) and other liver diseases (ie, alcoholic liver disease, alpha-antitrypsin deficiency, viral hepatitis, and primary sclerosing cholangitis), and autoimmune diseases such as systemic lupus erythematosus and rheumatoid arthritis. Of the remaining 125 patients, 77 (61.6%) were PBC-only and 48 (38.4%) were PBC-SS patients.The mean follow-up duration was 8.76 years. During the observation period, the incidence of interstitial lung disease was higher in the PBC-SS group than in the PBC-only group (P = 0.005). The occurrence of spontaneous bacterial peritonitis was significantly different in PBC-SS patients than in PBC-only patients (P = 0.002). The overall survival was lower in PBC-SS patients than in PBC-only patients (P = 0.033). Although the incidence of hepatocellular carcinoma, end-stage renal disease, variceal bleeding, and hypothyroidism were all higher in the PBC-SS group than in the PBC-only group, the differences were not significant.Our study suggests that PBC-SS patients have a higher risk of developing interstitial lung disease and spontaneous bacterial peritonitis and have a poor prognosis. Aggressive surveillance of thyroid and pulmonary functions should therefore be performed in these patients.

    Although significant progress has been made in the area of injectable hydrogels for biomedical applications and model cell niches, further improvements are still needed, especially in terms of mechanical performance, stability, and biomimicry of the native fibrillar architecture found in the extracellular matrix (ECM). This work focuses on the design and production of a silk-elastin-based injectable multiblock corecombinamer that spontaneously forms a stable physical nanofibrillar hydrogel under physiological conditions. That differs from previously reported silk-elastin-like polymers on a major content and predominance of the elastin-like part, as well as a more complex structure and behavior of such a part of the molecule, which is aimed to obtain well-defined hydrogels. Rheological and DSC experiments showed that this system displays a coordinated and concomitant dual gelation mechanism. In a first stage, a rapid, thermally driven gelation of the corecombinamer solution takes place once the system reaches body temperature due to the thermal responsiveness of the elastin-like (EL) parts and the amphiphilic multiblock design of the corecombinamer. A bridged micellar structure is the dominant microscopic feature of this stage, as demonstrated by AFM and TEM. Completion of the initial stage triggers the second, which is comprised of a stabilization, reinforcement, and microstructuring of the gel. FTIR analysis shows that these events involve the formation of β-sheets around the silk motifs. The emergence of such β-sheet structures leads to the spontaneous self-organization of the gel into the final fibrous structure. Despite the absence of biological cues, here we set the basis of the minimal structure that is able to display such a set of physical properties and undergo microscopic transformation from a solution to a fibrous hydrogel. The results point to the potential of this system as a basis for the development of injectable fibrillar biomaterial platforms

In the presence of decreased cognitive capacity as with dementia, the relationship between cognition and increasing pain is unknown in the elderly.Patients and methods: Longitudinal cohort design. Data collected from the Minimum Data Set-Resident Assessment Instrument (MDS-RAI from the 2001–2003 annual assessments of nursing home residents. A covariance model was used to evaluate the relationship between cognition and pain at three intervals.Results: The sample included 56,494 subjects from nursing homes across the United States, with an average age of 83 ± 8.2 years. Analysis of variance scores (ANOVAs indicated a significant effect (P < 0.01 for pain and cognition, with protected t test revealing scores decreasing significantly with these two measures. Relative stability was found for pain and cognition over time. Greater stability was found in the cognitive measure than the pain measure. Cross-legged effects observed between cognition and pain measures were inconsistent. A concomitant relationship was not found between cognition and pain. Even though the relationship was significant at the 0.01 level, the correlations were low (r ≤ 0.08, indicating a weak association between cognition and pain

    Full Text Available Introduction: Visceral artery aneurysms are rare vas-cular diseases whose pathogenesis and natural history remain incompletely understood. Herein we describe an 80 year-old man with concomitant superior mes-enteric, celiac, renal, and aorto-iliac aneurysms. To the best of our knowledge this constellation of arte-rial aneurysms has not been described yet."nCase Presentation: An 80-year-old man was referred to our institution due to presence of tarry stool and one episode of vomiting of coffee ground material. The patient underwent an upper GI endoscopy which revealed esophageal varicosities. Due to presence of esophageal varicosities and clinical suspicion of portal vein thrombosis an ultrasonographic Doppler study of portal venous system was performed in this patient which revealed normal diameter and flow in portal and splenic veins with no evidence of thrombosis; however incidentally aneurismal dilatation of celiac and superior mesenteric arteries and lower part of abdominal aorta and both iliac arteries were found during the ultrasonographic examination. Abdominal CT scan was performed in this patient, which re-vealed aneurismal dilatation of main celiac artery and its main branches. There was also aneurismal dilata-tion of superior mesenteric artery. Aneurismal dilata-tion of distal abdominal aorta with extension to both side common, external, and internal iliac arteries was also seen. MRA of abdomen was also performed which revealed the previous findings plus apparent dilatation of proximal part of right main renal artery which was not considered in previous abdominal CT scan. Since then; he has remained asymptomatic and stable, with no evidence of further expansion of his aneurysms in routine sonographic examinations."nDiscussion: Our patient was a hypertensive hyperlip-idemic old man with history of previous TIA and atherosclerotic carotid plaques, so the most important predisposing factor seemed to be atherosclerosis.

    BACKGROUND: Follow-up studies have shown that patients with ulcer disease are at risk of developing reflux esophagitis (RE) after successful eradication of Heliobacter pylori. It is still not clear whether this is induced by eradication of H. pylori or whether RE is already present at the time the ulcer is diagnosed. A cross-sectional study was done in consecutive patients suffering from active ulcer disease in order to assess coincidental RE. METHODS: Patients with an active duodenal or gastric ulcer were included in the study. Concomitant RE and the presence of hiatal hernia (HH) were scored. Biopsy specimens were taken for detection of H. pylori. RESULTS: In 375 patients (77%), an active duodenal ulcer was the only abnormality. In 43 patients (8.8%), duodenal ulcer and concomitant RE were present and 69 patients (14.2%) had a duodenal ulcer with concomitant HH. Patients with a duodenal ulcer were significantly younger than patients with concomitant RE or HH. From 374 patients (76.8%) with a duodenal ulcer, biopsy specimens were available for the detection of H. pylori. The majority of duodenal ulcer patients were H. pylori-positive. H. pylori was significantly more often present in patients with an active duodenal ulcer than it was in duodenal ulcer patients suffering from concomitant RE (P=0.04). In 218 patients (76%), a gastric ulcer was the only abnormality. Fifteen patients (5.2%) also had RE and 54 patients (18.8%) had a concomitant HH. There was no difference in H. pylori status in these three groups of patients. CONCLUSIONS: Given the low prevalence of concomitant RE, it is concluded that this condition is likely to occur in a large percentage of patients suffering from H. pylori-positive ulcer disease after successful eradication therapy.

    Full Text Available Sustainable marketing is a holistic approach that puts equal emphasis on environmental, social equity, and economic concerns in the development of marketing strategies. The purpose of the study is to examine and discuss the sustainable agricultural marketing initiatives practiced throughout the World and Turkey, and to put forth suggestions to further improve the performance of agricultural marketing initiatives in Turkey. Some of the sustainable agricultural marketing initiatives practiced around the world are carried out through civil organizations. Furthermore; some of these initiatives have also launched by farmers, consumers, food processors and retailers. The long-term strategies to increase these initiatives should be determined due to the fact that examples of successful sustainable agricultural marketing initiatives are inadequate and cannot be spread in Turkey. In this context, first of all, the supports provided by the government to improve agricultural marketing systems, such as EU funds for rural development should be compatible with the goals of sustainable marketing. For this purpose, it should be examined whether all proposed projects related to agricultural marketing meet the social, economic, and environmental principles of sustainable marketing. It is important that supporting organizations, especially civil society organisations, should take an active role for faster dissemination and adoption of sustainable agricultural marketing practices in Turkey. These organizations may provide technical assistance in preparing successful project proposals and training to farm groups. In addition, the other organizations, such as local administrations, producers' associations, cooperatives, can contribute to the success of sustainable agricultural marketing initiatives. The use of direct marketing strategies and vertical integration attempts in sustainable agricultural marketing initiatives that will likely be implemented in Turkey is

  13. Injuries as a result of sports and vacation activities: Fractures with concomitant vascular injuries. Diagnosis and treatment concept

    International Nuclear Information System (INIS)

    Extremity fractures with concomitant vascular injuries are surgical emergencies. Especially injuries of the upper extremities require a preoperative angiographic examination for the localization of the vascular lesion. In vascular lesions of the lower extremities a primary angiography is not necessary, if there is an opportunity for an intraoperative radiologic evaluation. In our traumatological department 104 patients were treated over the last 15 years with that combined injury. The concept of immediate stabilization of the fracture with simultaneous or postponed arterial repair has been proved to be appropriate. The fasziotomy as prophylactic procedure of a postischemic compartment syndrome is also a part of our concept during the last years. The late results in our mostly young patients depended on the degree of soft tissue damage and the time of ischemia. The often untreatable nerve lesions contributed to a loss of use of about 30% in the late courses. (orig.)

    Previous studies have demonstrated that B cells play critical roles in autoimmune disorders including systemic sclerosis (SSc) and systemic lupus erythematosus (SLE). However, the effectiveness of rituximab (RTX), a chimeric anti-CD20 antibody, for SSc-associated interstitial lung disease (ILD) or SLE disease activity remains controversial. We herein report an SSc patient with severely progressed ILD and concomitant SLE treated by two cycles of RTX at baseline and half a year later. This treatment improved ILD and SLE activities, along with reduction of dermal sclerosis and serum anti-topoisomerase I antibody levels. In addition, our detailed time-course data indicate that half a year may be appropriate as an interval between each cycle of RTX therapy aimed at SSc-associated ILD or SLE. Overall, the current report could pave the way to establish RTX as a disease-modifying drug for patients with SSc and/or SLE showing resistance to other already approved medications.

  15. THE PROBLEM OF STATIN USE IN PATIENTS WITH CARDIOVASCULAR DISEASES AND CONCOMITANT LIVER DISEASES. WHAT PREVENTS OVERCOMING STATINOPHOBIA?

    2016-01-01

    Full Text Available According to a recent study, Russian physicians often and sometimes unreasonably find it impossible to use statins in patients with cardiovascular diseases and concomitant chronic liver diseases. Analysis of domestic publications of recent years reveals the following factors which can impede overcoming statinophobia: 1 fragmentary and contradictory statement of the problem "Statins and liver" in Russian clinical guidelines for management of patients with high cardiovascular risk; 2 common perception that isolated transaminase increase in response to statin therapy is an indicator of "cytolysis" or "cytolytic syndrome"; 3 unreasonably overestimated lipid-lowering activity of combination therapy with low doses of statins and ursodeoxycholic acid; 4 view of the inadmissibility of statin use in patients with transaminase levels more than three upper limit of normal. To overcome these shortcomings and mistakes it seems appropriate to issue national clinical guidelines on statin use in high cardiovascular risk patients with underlying liver disease and/or with elevated transaminases.

    Full Text Available Background: Peripheral arterial disease is associated with adverse cardiovascular outcomes. As such, it is found that screening for peripheral arterial disease (PAD improves risk assessment. Thus, intensive risk factor modification and medical treatment in these patients are necessary. Objectives: The purpose of this study was to determine the prevalence of asymptomatic peripheral arterial disease in patients with concomitant coronary arterial disease. Methods: Asymptomatic peripheral arterial disease was investigated in 400 patients (60% males, 40% females, aged 59.7± 11.3 with a documented coronary arterial disease. Results: Among patients with documented CAD, 12% had asymptomatic PAD with the ABI ratio of less than 0.9. Conclusions: It is advisable to screen for PAD not only as a disease but also as a risk assessment method for atherosclerosis.

    Use of antimicrobial agents has been proposed as 1 of the factors that contribute to the loss of Helicobacter pylori (H. pylori) infection. The aim of the study was to investigate the influence of a previous treatment with antibiotics on the prevalence of H. pylori infection in preschool children. Parents of 146 asymptomatic children (aged 0.5-5 y; no antibiotic treatment during the previous 4 weeks) completed a questionnaire about previous treatment with antibiotics and socioeconomic status. Infection with H. pylori was assessed by the monoclonal stool antigen test. H. pylori positivity was 18% (27/146). It was significantly lower in children who had been treated with antibiotics previously compared to those who had been never treated (12.5% (12/96) vs 30% (15/50), p=0.01). It is concluded that previous antibiotic treatment for concomitant infections is associated with a lower prevalence of H. pylori infection in preschool children.

  19. Protocol for concomitant temporomandibular joint custom-fitted total joint reconstruction and orthognathic surgery utilizing computer-assisted surgical simulation.

    2013-12-01

    Clinicians who address temporomandibular joint (TMJ) pathology and dentofacial deformities surgically can perform the surgery in 1 stage or 2 separate stages. The 2-stage approach requires the patient to undergo 2 separate operations and anesthesia, significantly prolonging the overall treatment. However, performing concomitant TMJ and orthognathic surgery (CTOS) in these cases requires careful treatment planning and surgical proficiency in the 2 surgical areas. This article presents a new treatment protocol for the application of computer-assisted surgical simulation in CTOS cases requiring reconstruction with patient-fitted total joint prostheses. The traditional and new CTOS protocols are described and compared. The new CTOS protocol helps decrease the preoperative workup time and increase the accuracy of model surgery.

    Full Text Available Context With patients surviving longer after pancreatic resection, the challenges now is the management of the unresolved longerterm issues. Case report A 53-year-old woman with painless obstructive jaundice, underwent a pylorous preserving pancreaticoduodenectomy for a pT3N0M0 ampullary adenocarcinoma in 2001 (patchy chronic pancreatitis with mucinous metaplasia of background pancreatic duct epithelium and acinar atrophy were noted. Despite adjuvant chemotherapy, at month 54 she required a pulmonary wedge resection for metastatic adenocarcinoma, followed by a pulmonary relapse at 76 months when she underwent 6 neoadjuvant cycles of gemcitabine/capecitabine and a left pneumonectomy. Finally 7 years after the initial Whipple’s, a single 18F fluorodeoxyglucose (FDG avid pancreatic tail lesion led to completion pancreatectomy for a well-differentiated ductal adenocarcinoma with clear resection margins albeit peripancreatic adipose tissue infiltration. On review all resected tumour cells had identical immunophenotype (CK7+/CK20-/MUC1+/MUC2- as that of the primary. She is currently asymptomatic on follow-up. Conclusions These findings suggest that in selected cases even in the presence of pulmonary metastasis, repeat resections could result in long-term survival of patients with metachronous ampullary cancer. Second, even ampullary tumours maybe should be regarded as index tumors in the presence of ductal precursor lesions in the resection specimen. Three distant metastases, particularly if long after the initial tumour, should instigate a search for metachronous tumour, especially in the presence of field change in the initial specimen. Risk-adapted follow-up protocols with recognition of such factors could result in cost-effective surveillance and potentially improved outcomes.

    Purpose: Radiotherapy (RT) and chemotherapy may prolong survival in older patients (age {>=}70 years) with glioblastoma multiforme (GBM), although the survival benefits remain poor. This Phase II multicenter study was designed to evaluate the efficacy and safety of an abbreviated course of RT plus concomitant and adjuvant temozolomide (TMZ) in older patients with GBM. Patients and Methods: Seventy-one eligible patients 70 years of age or older with newly diagnosed GBM and a Karnofsky performance status {>=}60 were treated with a short course of RT (40 Gy in 15 fractions over 3 weeks) plus TMZ at the dosage of 75 mg/m{sup 2} per day followed by 12 cycles of adjuvant TMZ (150-200 mg/m{sup 2} for 5 days during each 28-day cycle). The primary endpoint was overall survival (OS). Secondary endpoints included progression-free survival and toxicity. Results: The Median OS was 12.4 months, and the 1-year and 2-year OS rates were 58% and 20%, respectively. The median and 1-year rates of progression-free survival were 6 months and 20%, respectively. All patients completed the planned programme of RT. Grade 3 or 4 adverse events occurred in 16 patients (22%). Grade 3 and 4 neutropenia and/or thrombocytopenia occurred in 10 patients (15%), leading to the interruption of treatment in 6 patients (8%). Nonhematologic Grade 3 toxicity was rare, and included fatigue in 4 patients and cognitive disability in 1 patient. Conclusions: A combination of an abbreviated course of RT plus concomitant and adjuvant TMZ is well tolerated and may prolong survival in elderly patients with GBM. Future randomized studies need to evaluate the efficacy and toxicity of different schedules of RT in association with chemotherapy.

  2. Concomitant targeting of EGF receptor, TGF-beta and SRC points to a novel therapeutic approach in pancreatic cancer.

    Sophie Deharvengt

    Full Text Available To test the hypothesis that concomitant targeting of the epidermal growth factor receptor (EGFR and transforming growth factor-beta (TGF-β may offer a novel therapeutic approach in pancreatic cancer, EGFR silencing by RNA interference (shEGFR was combined with TGF-β sequestration by soluble TGF-β receptor II (sTβRII. Effects on colony formation in 3-dimensional culture, tumor formation in nude mice, and downstream signaling were monitored. In both ASPC-1 and T3M4 cells, either shEGFR or sTβRII significantly inhibited colony formation. However, in ASPC-1 cells, combining shEGFR with sTβRII reduced colony formation more efficiently than either approach alone, whereas in T3M4 cells, shEGFR-mediated inhibition of colony formation was reversed by sTβRII. Similarly, in vivo growth of ASPC-1-derived tumors was attenuated by either shEGFR or sTβRII, and was markedly suppressed by both vectors. By contrast, T3M4-derived tumors either failed to form or were very small when EGFR alone was silenced, and these effects were reversed by sTβRII due to increased cancer cell proliferation. The combination of shEGFR and sTβRII decreased phospho-HER2, phospho-HER3, phoshpo-ERK and phospho-src (Tyr416 levels in ASPC-1 cells but increased their levels in T3M4 cells. Moreover, inhibition of both EGFR and HER2 by lapatinib or of src by SSKI-606, PP2, or dasatinib, blocked the sTβRII-mediated antagonism of colony formation in T3M4 cells. Together, these observations suggest that concomitantly targeting EGFR, TGF-β, and src may constitute a novel therapeutic approach in PDAC that prevents deleterious cross-talk between EGFR family members and TGF-β-dependent pathways.

  9. Thymidylate synthase, dihydropyrimidine dehydrogenase, ERCC1, and thymidine phosphorylase gene expression in primary and metastatic gastrointestinal adenocarcinoma tissue in patients treated on a phase I trial of oxaliplatin and capecitabine

    International Nuclear Information System (INIS)

    Over-expression of thymidylate synthase (TS) and dihydropyrimidine dehydrogenase (DPD) in tumor tissue is associated with insensitivity to 5-fluorouracil (5-FU). Over-expression of ERCC1 correlates with insensitivity to oxaliplatin (OX) therapy, while high thymidine phosphorylase (TP) levels predict for increased sensitivity to capecitabine (Xel). Biopsies of metastatic tumor were taken before OX (130 mg/m2 day 1) given with Xel (1200–3000 mg/m2 in two divided doses days 1–5 and 8–12) every 3-weeks. Micro-dissected metastatic and primary tumors were analyzed for relative gene expression by real-time quantitative polymerase chain reaction. The clinical protocol prospectively identified the molecular targets of interest that would be tested. Endpoints for the molecular analyses were correlation of median, first and third quartiles for relative gene expression of each target with response, time to treatment failure (TTF), and survival. Among 91 patients participating in this trial; 97% had colorectal cancer. The median number of prior chemotherapy regimens was 2, and most had prior 5-FU and irinotecan. In paired samples, median mRNA levels were significantly higher in metastatic versus primary tumor (-fold): TS (1.9), DPD (3.8), ERCC1 (2.1) and TP (1.6). A strong positive correlation was noted between DPD and TP mRNA levels in both primary (r = 0.693, p < 0.0005) and metastatic tissue (r = 0.697, p < 0.00001). There was an association between TS gene expression and responsive and stable disease: patients whose intratumoral TS mRNA levels were above the median value had significantly greater risk of early disease progression (43% vs 17%), but this did not translate into a significant difference in TTF. ERCC1 gene expression above the third quartile was associated with a shorter TTF (median 85 vs 162 days, p = 0.046). Patients whose TS mRNA levels in metastatic tumor tissue were below the median had a longer overall survival (median 417 vs 294 days, p = 0

    Full Text Available Current international and national treatment guidelines such as EACS, BHIVA, DHHS or IAS update regularly recommendations on the choice of initial combination antiretroviral treatment (cART regimens. Preferred cART regimens include a backbone with two nucleoside (nucleotide reverse transcriptase inhibitors combined either with one non-nucleoside reverse transcriptase inhibitor or one ritonavir boosted protease inhibitor or more recently one integrase inhibitor. Response rates according to viral load measurements increased in recent years, in particular due to better tolerability. The choice of initial therapy is flexible and influenced by several factors such as height of viral load, genotypic resistance testing, CD4 cell count, co-morbidities, interactions, potential adverse events, (potential for pregnancy, convenience, adherence, costs as well as physician's and patient's preferences. Diverse highly potent initial cART regimens exist. Following the many possibilities, the choice of a regimen is based on a mixture of evidence-informed data and individualized concepts, some of the latter only partly supported by strong evidence. For example, different perceptions and personal experiences exist about boosted protease inhibitors compared to non-nucleoside reverse transcriptase inhibitors or integrase inhibitors and vice versa which may influence the initial choice. This lecture will discuss choices of initial cART in view of international guidelines and the evidence for individualization of initial HIV therapy.

    V N, Panicker; J K, Turner; M J, Chehade

    2014-01-01

    Tophaceous gout complicated by septic arthritis presents a management dilemma which can often require multiple surgical debridements. There is little published in the literature regarding treatment of these concomitant conditions. We postulate that biofilm may play a role increasing the difficulty of sterilising a tophaceous joint. The use of topical negative pressure therapy that targets biofilm has been well established for a range of wounds. A new device that incorporates both intermittent negative pressure therapy and wound irrigation was introduced in 2012. This case report describes the use of this topical negative device with the instillation option in the management of severe septic arthritis with concomitant gout and suggests directions for further research.

    Purpose: The aim of this study was to evaluate the long-term clinical efficacy and toxicity of concomitant boost and accelerated hyperfractionated radiation therapy (CBAHRT) in patients with invasive bladder cancer. Methods and Materials: Between October 1997 and September 2012, 334 patients with diagnoses of invasive bladder cancer were selected. These patients received CBAHRT as a bladder-conserving approach. The treatment consisted of a dose of 45 Gy/1.8 Gy to the whole pelvis with a daily concomitant boost of 1.5 Gy to the tumor. Total dose was 67.5 Gy in 5 weeks. A total of 32 patients (10.3%) had a diagnosis of stage T1, 202 (64.3%) were at stage T2, 46 (14.6%) were at stage T3a, 22 (7%) were at stage T3b, and 12 (3.8%) were at stage T4a. Results: The follow-up period was 33.1 months (range, 4.3-223.3 months). Grade 3 late intestinal toxicity was observed in 9 patients (2.9%), whereas grade 3 late urinary toxicity was observed in 8 patients (2.5%). The median overall survival (OS) was 26.3 months (95% confidence interval [CI]: 21.4-31.2). The 5-, 10, and 15-year OS rates were 32.1% (standard error [SE], ± 0.027), 17.9% (SE, ± 0.025) and 12.5% (SE, ± 0.028), respectively. The median cause-specific survival (CSS) was 42.1 months (95% CI: 28.7-55.5). The 5-, 10-, and 15-year CSS rates were 43.2% (SE, ± 0.03), 30.3% (SE, ± 0.03), and 28% (SE, ± 0.04), respectively. The median relapse-free survival (RFS) was 111.8 months (95% CI: 99.6-124). The 5-, 10-, and 15-year RFS rates were 61.9% (SE, ± 0.03), 57.6% (SE, ± 0.04), and 48.2% (SE, ± 0.07)
