    Fifteen patients with metastatic breast cancer previously treated with chemotherapy were treated with a regimen consisting of vincristine, Adriamycin, and mitomycin. Eleven patients (73%) responded with three complete and eight partial responses. The median duration of response was eight months. While all four nonresponders died within five months, the median duration of survival of responders was 18 months. Toxicity was significant but tolerable. Thus, this preliminary report suggests that this regimen is active in advanced previously treated breast cancer, providing meaningful remissions with acceptable toxicity.

    Purpose The aim of this nationwide, register-based cohort study was to determine whether women treated for depression before primary early-stage breast cancer are at increased risk for receiving treatment that is not in accordance with national guidelines and for poorer survival. Material...... and Methods We identified 45,325 women with early breast cancer diagnosed in Denmark from 1998 to 2011. Of these, 744 women (2%) had had a previous hospital contact (as an inpatient or outpatient) for depression and another 6,068 (13%) had been treated with antidepressants. Associations between previous...... treatment of depression and risk of receiving nonguideline treatment of breast cancer were assessed in multivariable logistic regression analyses. We compared the overall survival, breast cancer-specific survival, and risk of death by suicide of women who were and were not treated for depression before...

    PURPOSE: To report the incidence of cancer in a cohort of adolescent idiopathic scoliosis (AIS) patients treated 25 years previously. METHODS: 215 consecutive AIS patients treated between 1983 and 1990 were identified and requested to return for clinical and radiographic examination. The incidence...... of cancer was determined through chart review and follow-up interviews. Using the original radiographic log file that included patient position, mAs, kV and the total number of X-rays taken, a radiation physicist calculated the total radiation dose during treatment and follow-up adjusted for BMI and sex...... radiation exposure was 0.8-1.4 mSV per examination and 2.4-5.6 mSv/year. An average of 16 radiographs were taken during the treatment period. Nine AIS patients developed cancer, mostly breast (3) and endometrial (4). The AIS patients had a relative risk of 4.8 (CI 2.3-5.8, p

    Full Text Available Abstract Background Secondary radiation-induced cancers are rare but well-documented as long-term side effects of radiation in large populations of breast cancer survivors. Multiple neoplasms are rare. We report a case of esophageal adenocarcinoma in a patient treated previously for breast cancer and clear cell carcinoma of the kidney. Case presentation A 56 year-old non smoking woman, with no alcohol intake and no familial history of cancer; followed in the National Institute of Oncology of Rabat Morocco since 1999 for breast carcinoma, presented on consultation on January 2011 with dysphagia. Breast cancer was treated with modified radical mastectomy, 6 courses of chemotherapy based on CMF regimen and radiotherapy to breast, inner mammary chain and to pelvis as castration. Less than a year later, a renal right mass was discovered incidentally. Enlarged nephrectomy realized and showed renal cell carcinoma. A local and metastatic breast cancer recurrence occurred in 2007. Patient had 2 lines of chemotherapy and 2 lines of hormonotherapy with Letrozole and Tamoxifen assuring a stable disease. On January 2011, the patient presented dysphagia. Oesogastric endoscopy showed middle esophagus stenosing mass. Biopsy revealed adenocarcinoma. No evidence of metastasis was noticed on computed tomography and breast disease was controlled. Palliative brachytherapy to esophagus was delivered. Patient presented dysphagia due to progressive disease 4 months later. Jejunostomy was proposed but the patient refused any treatment. She died on July 2011. Conclusion We present here a multiple neoplasm in a patient with no known family history of cancers. Esophageal carcinoma is most likely induced by radiation. However the presence of a third malignancy suggests the presence of genetic disorders.

    Background and objective Pemetrexed have been approved for the treatment of patients affected by advanced non-small cell lung cancner (NSCLC) in progression after first-line chemotherapy. We evaluated the activity and feasibility of pemetrexed in previously treated NSCLC.Methods Patients with histologically or cytologically confirmed NSCLC were evaluated from April 2007 to March 2009. The patients had relapsed or progressed after prior chemotherapy treatment. Pemetrexed (500 mg/m2) was administered intravenously once every 3 weeks after progression to prior chemotherapy. The tumor response was evaluated according to RECIST criteria by chest CT at every 2 cycles of chemotherapy.Results A total 61 patients were eligible for analysis. Performance status of them (100%) was over 2. The response rate and disease control rate were 14.7% and 37.7% respectively. Non-squamous cell carcinoma histology was significantly associated with a superior response rate (P=0.045) and disease control rate (P=0.008). The median survival time and the median progression free survival (PFS) time were 6.11 months and 2.17 months, respectively. Comparing the efficacy of pemetrexed in these two settings [second-line versus (12/61) more than third (49/61)], there was no significant difference in regard to median survival (11.18 months vs 11.46 months, P=0.922,S), but PFS was more longer in third- or further-line groups than second-line group (1.39 months vs 2.25 months, P=0.015,3).Conclusion Pemetrexed is a feasible regimen in previously treated NSCLC with poor performance status.

    Full Text Available BACKGROUND: Data on birth outcome and offspring health after the appearance of breast cancer are limited. The aim of this study was to assess the risk of adverse birth outcomes in women previously treated for invasive breast cancer compared with the general population of mothers. METHODS AND FINDINGS: Of all 2,870,932 singleton births registered in the Swedish Medical Birth Registry during 1973-2002, 331 first births following breast cancer surgery--with a mean time to pregnancy of 37 mo (range 7-163--were identified using linkage with the Swedish Cancer Registry. Logistic regression analysis was used. The estimates were adjusted for maternal age, parity, and year of delivery. Odds ratios (ORs and 95% confidence intervals (CIs were used to estimate infant health and mortality, delivery complications, the risk of preterm birth, and the rates of instrumental delivery and cesarean section. The large majority of births from women previously treated for breast cancer had no adverse events. However, births by women exposed to breast cancer were associated with an increased risk of delivery complications (OR 1.5, 95% CI 1.2-1.9, cesarean section (OR 1.3, 95% CI 1.0-1.7, very preterm birth (<32 wk (OR 3.2, 95% CI 1.7-6.0, and low birth weight (<1500 g (OR 2.9, 95% CI 1.4-5.8. A tendency towards an increased risk of malformations among the infants was seen especially in the later time period (1988-2002 (OR 2.1, 95% CI 1.2-3.7. CONCLUSIONS: It is reassuring that births overall were without adverse events, but our findings indicate that pregnancies in previously treated breast cancer patients should possibly be regarded as higher risk pregnancies, with consequences for their surveillance and management.

    The effects of docetaxel treatment on autonomic cardiac function was studied with 24-h ECG recordings in breast cancer patients pretreated with anthracyclines. Twenty-four women were evaluated before docetaxel treatment and after 3-4 courses of docetaxel 100 mg/m(2). The heart rate, cardiac extrasystoles and heart rate variability (HRV) in both the time and frequency domain were assessed from 24-h ECG recordings. The acute effects of docetaxel were calculated from 1-h recordings immediately prior to, during and after infusion. Long-term effects were evaluated from 24-h recordings performed before treatment and after 3-4 courses of docetaxel. There was no increase in the number of cardiac extrasystoles during docetaxel infusion. The number of ventricular extrasystoles decreased from 14 (23) to 7 (14) during and 5 (10) after the first infusion (p=0.02). The heart rate, HRV and extrasystoles were similar before and after 3-4 courses of docetaxel. The treatment did not abolish circadian variability of the heart rate. Docetaxel did not deteriorate autonomic cardiac function. In conclusion, our findings suggest that docetaxel does not have harmful cumulative effects on autonomic control of the heart and is therefore unlikely to be cardiotoxic.

    Full Text Available Background and objective Erlotinib is a small molecular inhibitor of tyrosine kinase. One study has confirmed that it can prolong the median progression-free survival time (PFS, and can improve the one-year survival rate of patients with advanced non-small cell lung cancer. The aim of this trial is to evaluate the response and adverse reaction of agent erlotinib in advanced and previously treated non-small-cell lung cancer. Methods The study was one part of the EAP (Expanded Access Programme study. Forty-five patients with advanced non-small cell lung cancer, which had been treated with 1-2 regimens containing platinum previously, were treated with erlotinib from Dec 2005. Erlotinib was prescribed at a dose of 150 mg daily. Results Forty-three patients were evaluated response and all patients were evaluated toxicity. Among these patients, CR 0 case, PR 19 cases (44.2%, RR (CR+PR 44.2% and SD 13 cases as their best response, disease control rate (DCR=CR+PR+SD 74.4%, PD 11cases (25.6%. The median progression-free survival time was 4.8 months; the median survival time was 15.0 months; the one-year survival rate was 68.8% (31/45. The median PFS of patients with adenocarcinoma and with non-adenocarcinoma was 7.6 months vs 2.6 months (P=0.018. The drug-related adverse reactions were skin rash (41 cases, 91.1%, billirubine increased (15 cases, 33.3%, ALT increased (9 cases, 20% and diarrhea (4 cases, 8.9%. For patients with and without skin rash, the median PFS was 7.5 months vs 1.1 months (P=0.001, and the median survival time was 15.6 months vs 5.2 months (P=0.002. Conclusion Erlotinib is effective in advanced and previously treated non-small cell lung cancer, and it is much more effective in adenocarcinoma and patients with skin rash. It is well tolerated, only with some minimal adverse reactions.

    This multicenter, open-label, phase II study was performed to assess the efficacy and toxicity of irinotecan 350 mg/m2 intravenously every 3 weeks in patients with advanced colorectal cancer (CRC) previously treated with 5-fluorouracil (5-FU). The study enrolled 115 patients and a total of 558 cycles (median, 6 per patient) were administered. The overall objective response rate on an intent-to-treat basis was 18% (with 1 complete response and 20 partial responses), whereas 42 patients (37%) showed stable disease. Median time to progression was 4.8 months and median survival was 13.6 months. Grade 3/4 toxicities included delayed diarrhea (19.1%), nausea/vomiting (10.4%), and neutropenia (8.7%). There were 2 toxic deaths, 1 from delayed diarrhea and 1 from hemorrhage and grade 4 mucositis. In conclusion, the present study confirms the antitumor efficacy of irinotecan monotherapy in patients with CRC pretreated with 5-FU.

    The activation of lymphocytes by gefitinib treatment has been described. In this phase II pilot trial, we explored the possible synergism between IL-2 and gefitinib for non-small cell lung cancer (NSCLC) treatment. From September, 2003, to November, 2006, 70 consecutive patients with advanced, progressive NSCLC, previously treated with chemotherapy, received oral gefitinib 250 mg daily. The first 39 patients received gefitinib alone (G group). The other 31 also received subcutaneous IL-2 (GIL-2 group): 1 MIU/m{sup 2} (Million International Unit/m{sup 2})twice a day on Days 1 and 2, once a day on Days 3, 4, 5 every week for four consecutive weeks with a four-week rest period. Median follow-up was 25.2 months. Grade 3–4 toxicity of gefitinib was represented by skin rash (7%), asthenia/anorexia (6%) and diarrhea (7%); patients treated with IL-2 showed grade 2–3 fever (46%), fatigue (21%) and arthralgia (13%). In the GIL-2 group and G-group, we respectively observed: an overall response rate of 16.1% (6.4% complete response) and 5.1% (only partial response); a disease control rate of 41.9% and 41%; a median time to progression of 3.5 (CI 95% = 3.2–3.8) and 4.1 (CI 95% = 2.6–5.7) months; a median overall survival of 20.1 (CI 95% = 5.1–35.1) and 6.9 (CI 95% = 4.9–8.9) months (p = 0.002); and an actuarial one-year survival rate of 54% and 30%. Skin toxicity (p < 0.001; HR = 0.29; CI 95% = 0.16–0.54) and use of IL-2 (p < 0.001; HR = 0.33; CI 95% = 0.18–0.60) were independently associated with improvement of survival. In this consecutive, non-randomized, series of advanced NSCLC patients, the use of IL-2 increased the efficacy of gefitinib.

    Src tyrosine kinases are overexpressed in pancreatic cancers, and the oral Src inhibitor saracatinib has shown antitumor activity in preclinical models of pancreas cancer. We performed a CTEP-sponsored Phase II clinical trial of saracatinib in previously treated pancreas cancer patients, with a primary endpoint of 6-month survival. A Simon MinMax two-stage phase II design was used. Saracatinib (175 mg/day) was administered orally continuously in 28-day cycles. In the unselected portion of the study, 18 patients were evaluable. Only two (11%) patients survived for at least 6 months, and three 6-month survivors were required to move to second stage of study as originally designed. The study was amended as a biomarker-driven trial (leucine rich repeat containing protein 19 [LRRC19] > insulin-like growth factor-binding protein 2 [IGFBP2] "top scoring pairs" polymerase chain reaction [PCR] assay, and PIK3CA mutant) based on preclinical data in a human pancreas tumor explant model. In the biomarker study, archival tumor tissue or fresh tumor biopsies were tested. Biomarker-positive patients were eligible for the study. Only one patient was PIK3CA mutant in a 3' untranslated region (UTR) portion of the gene. This patient was enrolled in the study and failed to meet the 6-month survival endpoint. As the frequency of biomarker-positive patients was very low (pancreatic cancer patients treated with a Src inhibitor based on a biomarker would improve 6-month survival, we demonstrate that testing pancreatic tumor samples for a biomarker-driven, multicenter study in metastatic pancreas cancer is feasible.

    Consumption of cruciferous vegetables has been associated with reduced breast cancer risk mechanistically and in population-based studies, although evidence has been inconsistent. This inconsistency may be related to limitations in quantifying and qualifying cruciferous vegetable exposure using standard instruments for dietary assessment (for example, food-frequency questionnaires, FFQs) or due to low levels of intake demonstrated among U.S. population samples. Cruciferous vegetable intake data are presented from a longitudinal study of a high-vegetable dietary intervention to reduce breast cancer recurrence among breast cancer survivors (n=1,156; 536 intervention and 620 comparison group subjects). Intake was assessed using repeat administration of an FFQ and cross-sectional administration of a cruciferous vegetable-specific FFQ (CVFFQ). Mean intake in the intervention group assessed using the standard FFQ was 37.7 g/day at baseline and increased to 57.1 g/day at 12 mo (P=0.0001) and was sustained through 48 mo. Broccoli and cabbage were the most commonly consumed cruciferous vegetables, regardless of the instrument used to assess intake. Differences in intake by group assignment were shown for raw cruciferous vegetables (30.2 g/day vs. 24.6 g/day, assessed using the CVFFQ), suggesting increased exposure to biologically active, cancer-preventive food constituents. These data suggest that this study population will be the first U.S. population sample to provide ample quantity and variety in cruciferous intake to examine whether these vegetables are protective against breast cancer recurrence.

    Full Text Available Abstract Background The main objective of this study was to evaluate the safety of second-line pemetrexed in Stage IIIB or IV NSCLC. Methods Overall, 95 patients received pemetrexed 500 mg/m2 i.v. over Day 1 of a 21-day cycle. Patients also received oral dexamethasone, oral folic acid and i.m. vitamin B12 supplementation to reduce toxicity. NCI CTC 2.0 was used to rate toxicity. All the adverse events were graded in terms of severity and relation to study treatment. Dose was reduced in case of toxicity and treatment was delayed for up to 42 days from Day 1 of any cycle to allow recovering from study drug-related toxicities. Tumor response was measured using the RECIST criteria. Results Patients received a median number of 4 cycles and 97.8% of the planned dose. Overall, 75 patients (78.9% of treated reported at least one adverse event: 34 (35.8% had grade 3 as worst grade and only 5 (5.2% had grade 4. Drug-related events occurred in 57.9% of patients. Neutropenia (8.4% and leukopenia (6.3 % were the most common grade 3/4 hematological toxicities. Grade 3 anemia and thrombocytopenia were reported in 3.2% and 2.1% of patients, respectively. Diarrhea (6.3%, fatigue (3.2% and dyspnea (3.2% were the most common grade 3/4 non-hematological toxicities. The most common drug-related toxicities (any grade were pyrexia (11.6%, vomiting, nausea, diarrhea and asthenia (9.5% and fatigue (8.4%. Tumor Response Rate (CR/PR in treated patients was 9.2%. The survival at 4.5 months (median follow-up was 79% and the median PFS was 3.1 months. Twenty patients (21.1% died mainly because of disease progression. Conclusion Patients with locally advanced or metastatic NSCLC could benefit from second-line pemetrexed, with a low incidence of hematological and non-hematological toxicities.

    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.

    Thirty-six evaluable patients with advanced breast cancer who had failed prior CMF therapy [15 (42%) as adjuvant treatment and 21 (58%) for advanced disease] were treated with a combination of vincristine, doxorubicin, and mitomycin (VAM). There was one CR and 10 PR, giving a response rate of 31% (P, 95% confidence interval, 15%-47%). Response was not significantly related to age, performance status, disease-free interval, dominant site of disease, number of sites of disease, or estrogen receptor status. The median duration of response was 5 months for patients attaining CR or PR and 4.6 months for patients with stable disease. The median survival for patients with CR or PR of 7.9 months was not better than for those with stable disease (8.0 months), but both groups had significantly longer survival than those with initial progression. Patients who received VAM after failing adjuvant CMF had a 53% response rate (8 of 15), as against a 14% response rate (3 of 21) in those failing CMF for advanced disease (P less than 0.05). In spite of this difference, the survival distributions for these two groups were not significantly different. Myelosuppression was moderate and no cardiac toxicity was seen. The addition of mitomycin to vincristine and doxorubicin in previously treated patients does not appear to improve the results obtained with vincristine and doxorubicin alone.

    Radiofrequency ablation (RFA) recently has been applied to benign thyroid nodules, mainly for the cosmetic reasons, and limited cases of local recurrences or focal distant metastases of well-differentiated thyroid cancer, in the high-risk reoperative condition or for the palliative purpose. But no report has been made on the RFA for primary thyroid cancer to date. We report on a patient with primary papillary carcinoma of thyroid gland who had undergone RFA before the cytological diagnosis of malignancy, later referred and treated with robotic surgery successfully. We can learn the following lessons from our case; (1) the RFA for operable primary thyroid malignancy should be avoided, because of the possibility of remnant viable cancer and undetectable nodal metastasis, and (2) robotic or endoscopic thyroid surgery may be a feasible operative method for benign or malignant thyroid nodules previously treated with RFA.

    Full Text Available Abstract Background To prospectively evaluate the efficacy and safety of selective internal radiation (SIR spheres in patients with inoperable liver metastases from colorectal cancer who have failed 5FU based chemotherapy. Methods Patients were prospectively enrolled at three Australian centres. All patients had previously received 5-FU based chemotherapy for metastatic colorectal cancer. Patients were ECOG 0–2 and had liver dominant or liver only disease. Concurrent 5-FU was given at investigator discretion. Results Thirty patients were treated between January 2002 and March 2004. As of July 2004 the median follow-up is 18.3 months. Median patient age was 61.7 years (range 36 – 77. Twenty-nine patients are evaluable for toxicity and response. There were 10 partial responses (33%, with the median duration of response being 8.3 months (range 2–18 and median time to progression of 5.3 mths. Response rates were lower (21% and progression free survival shorter (3.9 mths in patients that had received all standard chemotherapy options (n = 14. No responses were seen in patients with a poor performance status (n = 3 or extrahepatic disease (n = 6. Overall treatment related toxicity was acceptable, however significant late toxicity included 4 cases of gastric ulceration. Conclusion In patients with metastatic colorectal cancer that have previously received treatment with 5-FU based chemotherapy, treatment with SIR-spheres has demonstrated encouraging activity. Further studies are required to better define the subsets of patients most likely to respond.

    Background Icotinib is a small molecule targeting epidermal growth factor receptor tyrosine kinase, which shows non-inferior efficacy and better safety comparing to gefitinib in previous phase III trial. The present study was designed to further evaluate the efficacy and safety of icotinib in patients with advanced non-small-cell lung cancer (NSCLC) previously treated with platinum-based chemotherapy. Methods Patients with NSCLC progressing after one or two lines of chemotherapy were enrolled to receive oral icotinib (125mg tablet, three times per day). The primary endpoint was progression-free survival. The secondary endpoints included overall survival, objective response rate, time to progression, quality of life and safety. Results From March 16, 2010 to October 9, 2011, 128 patients from 15 centers nationwide were enrolled, in which 124 patients were available for efficacy evaluation and 127 patients were evaluable for safety. The median progression-free survival and time to progression were 5.0 months (95%CI 2.9–6.6 m) and 5.4 months (95%CI 3.1–7.9 m), respectively. The objective response rate and disease control rate were 25.8% and 67.7% respectively. Median overall survival exceeded 17.6 months (95%CI 14.2 m-NA) according to censored data. Further follow-up of overall survival is ongoing. The most frequent treatment-related adverse events were rash (26%, 33/127), diarrhea (12.6%, 16/127) and elevation of transaminase (15.7%, 20/127). Conclusions In general, this study showed similar efficacy and numerically better safety when compared with that in ICOGEN trial, further confirming the efficacy and safety of icotinib in treating patients with advanced NSCLC previously treated with chemotherapy.

    Full Text Available Endovascular treatment with coils of cerebral aneurysm is being increasingly used for definitive treatment. An increasing number of patients are coming for surgical intervention either for recurrences, incomplete coil embolization or its complications. Our objective was to assess the surgical management in such patients. This was a retrospective analysis of the patients who were initially treated with endovascular embolization and later managed surgically with clipping either for unsuccessful coiling, recurrence of aneurysm or post-procedural complication, between 2003 and 2007. Anatomical results were excellent in all five patients, and all the aneurysms were totally excluded from the circulation. All patients had good recovery. None of the patients suffered any major intraoperative or postoperative complication. Neurosurgical management of intracranial aneurysms previously treated with endovascular therapy is an emerging challenge, but with proper patient selection and careful planning, this subset of aneurysms can be managed with good results.

    The French Groupe des Investigateurs Nationaux pour l'Etude des Cancers Ovariens (GINECO) conducted a multicenter phase II study of carboplatin and paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ) to evaluate the efficacy and side effects of this combination in pretreated advanced ovarian cancer. Patients with progressive ovarian carcinoma during or after platinum-based chemotherapy received paclitaxel 175 mg/m2 intravenously over 3 hours followed by intravenous carboplatin over 30 minutes every 4 weeks. The dose of carboplatin was calculated using a projected area under the concentration-time curve of 5 mg/mL x min. Of the 50 patients entered, 50 were evaluable for toxicity and 42 for response. There were eight complete and 10 partial responses, for an overall response rate of 43% (95% confidence interval, 28% to 56%). Overall response rates in platinum refractory patients and in those with early (> or = 3 and or = 12 months) relapse was 28%, 33%, and 71%, respectively. Median response duration, progression-free survival, and overall survivals were 8, 6, and 14 months, respectively. The most frequent and severe toxicity was myelosuppression. Grades 3 and 4 neutropenia occurred in 30% and 23% of cycles, and granulocyte colony-stimulating factor was administered in 6%. Only one case of neutropenic fever was observed. Grades 3 and 4 thrombocytopenia occurred in 3% and 1% of cycles, respectively. Alopecia and moderate nausea or vomiting were frequent. Transitory peripheral neuropathy was present in 45% of patients but was severe in only one patient. One early death was observed due to progressive disease and possibly to therapy. The combination of paclitaxel 175 mg/m2 as a 3-hour infusion and carboplatin dosed to an area under the concentration-time curve of 5 is an effective therapy in patients previously treated with platinum-based chemotherapy and may be administered safely to outpatients who relapse after one or two lines of chemotherapy.

    Full Text Available Background and objective It has been proven that gefitinib produces only 10%-20% tumor regression in heavily pretreated, unselected non-small cell lung cancer (NSCLC patients as the second- and third-line setting. Asian, female, nonsmokers and adenocarcinoma are favorable factors; however, it is difficult to find a patient satisfying all the above clinical characteristics. The aim of this study is to identify novel predicting factors, and to explore the interactions between clinical variables and their impact on the survival of Chinese patients with advanced NSCLC who were heavily treated with gefitinib in the second- or third-line setting. Methods The clinical and follow-up data of 127 advanced NSCLC patients referred to the Cancer Hospital & Institute, Chinese Academy of Medical Sciences from March 2005 to March 2010 were analyzed. Multivariate analysis of progression-free survival (PFS was performed using recursive partitioning, which is referred to as the classification and regression tree (CART analysis. Results The median PFS of 127 eligible consecutive advanced NSCLC patients was 8.0 months (95%CI: 5.8-10.2. CART was performed with an initial split on first-line chemotherapy outcomes and a second split on patients’ age. Three terminal subgroups were formed. The median PFS of the three subsets ranged from 1.0 month (95%CI: 0.8-1.2 for those with progressive disease outcome after the first-line chemotherapy subgroup, 10 months (95%CI: 7.0-13.0 in patients with a partial response or stable disease in first-line chemotherapy and age <70, and 22.0 months for patients obtaining a partial response or stable disease in first-line chemotherapy at age 70-81 (95%CI: 3.8-40.1. Conclusion Partial response, stable disease in first-line chemotherapy and age ≥ 70 are closely correlated with long-term survival treated by gefitinib as a second- or third-line setting in advanced NSCLC. CART can be used to identify previously unappreciated patient

    Full Text Available Abstract Skeletal muscle wasting is a major component of cachectic states found in a variety of disease settings, including cancer. As increasing caloric intake often provides little benefit in combating muscle loss in cachectic patients, a major research focus has been to develop strategies stimulating muscle anabolic pathways - in an attempt to fight the catabolic pathways induced during cachexia. Two recent papers have reported the beneficial effects of blocking the myostatin/activin signalling pathway in mouse models of cancer cachexia. We discuss the implications of their findings both with respect to the role that this signalling pathway may play in the aetiology of cachexia and with respect to the prospects for targeting this pathway as a therapeutic strategy in patients with cachexia.

    Invasive carcinoma found after simple hysterectomy for several causes is an increasing clinical condition. That situation results in the necessity for further therapy: re-operation or radiotherapy. The purpose of this review is to analyze our results with postoperative radiotherapy for these patients. In 1998, 59 patients were submitted to postoperative radiotherapy at the Oncology Hospital, Medical Cancer Center for invasive cervical cancer found after simple hysterectomy for several causes. All patients had postoperative radiotherapy, the dose depended of the magnitude of residual disease after surgery (range 10-80 Gy). After surgery 27 patients had gross residual disease; and no residual disease or microscopic disease was present in 32 patients. Three years overall survival rate was 59% for the whole group. With the results of the univariate analysis, prognostic factors found that significantly affect disease free survival were interval between hysterectomy and radiotherapy of more than 6 months, radiotherapy dose less than 50 Grays and histology. With multivariate analysis only presence of gross residual disease affect significantly disease free survival p = 0.0000. Postoperative radiotherapy results in patients with invasor cervical cancer incidentally found in hysterectomy specimens with minimal residual disease are excellent. However with the presence of more extensive residual disease the results in disease free survival are worse than those obtained in patients with similar stages who had not been treated with hysterectomy. A well established diagnostic procedure must be done in all patients candidates to simple hysterectomy.

    Purpose: To investigate the safety and efficacy of single-dose 8-Gy palliative chest reirradiation (CRI) in metastatic non-small cell lung cancer (M-NSCLC) patients with painful thoracic failures (TF) within the previous radiation portal. Patients and Methods: We retrospectively analyzed the clinical data of 78 M-NSCLC patients who received single-dose 8-Gy CRI for painful TF after concurrent chemoradiation therapy to a total radiation dose of 52 to 66 Gy between 2007 and 2012. Primary endpoints included significant pain relief (SPR) defined as a ≥2 point decrement in the Visual Analogue Scale for Pain inventory (VAS-P), time to pain relief, and duration of pain control. Secondary objectives were survival and prognostic factors. Results: Treatment was well tolerated, with only 5.1% grade 3 pneumonitis and 1.3% grade 2 esophagitis. Pre-CRI median and post-CRI minimum VAS-P were 7 and 3 (P<.001), respectively. SPR was noted in 67 (85.9%) patients, and only 3 (3.9%) scored progressive pain. Median time to lowest VAS-P and duration of pain control were 27 days and 6.1 months, respectively. Median overall survival (OS) was 7.7 months, and the 1-year OS rate was 26.5%. On multivariate analyses, lower Eastern Cooperative Oncology group score (1-2; P<.001), absence of anemia (P=.001), and fewer metastatic sites (1-2; P<.001) were found to be associated with longer OS. Conclusions: Single-dose 8-Gy CRI provides safe, effective, and durable pain palliation for TF in radically irradiated M-NSCLC patients. Because of its convenience, lower cost, and higher comfort, the present protocol can be considered an appropriate option for patients with limited life spans.

  3. Nanotherapies for treating prostate cancer

    Science.gov (United States)

    Danquah, Michael

    Current prostate cancer treatment remains ineffective primarily due to ineffectual therapeutic strategies and numerous tumor-associated physiological barriers which hinder efficacy of anticancer agents. Therefore, the focus of this study was to investigate a new combination therapy approach for treating prostate cancer and develop polymeric nanocarriers to facilitate anticancer drug and nucleic acid delivery. It was hypothesized that simultaneously targeting androgen-androgen receptor (AR) and X-linked inhibitor of apoptosis protein (XIAP) signaling pathways would be effective in treating prostate cancer. The effect of bicalutamide (antiandrogen) and embelin (XIAP inhibitor) on the growth of prostate cancer cells in vitro and in vivo was first examined. Embelin induced caspase 3 and 9 activation in LNCaP and C4-2 cells by decreasing XIAP expression and was more potent than bicalutamide in killing prostate tumor cells irrespective of their androgen status. Using a combination of MTT assay and isobologram analyses, combination of bicalutamide and embelin was observed to be cell line and schedule dependent. Since bicalutamide and embelin are extremely hydrophobic, polymeric micelles were fabricated using polyethylene glycol-b-polylactic acid (PEG-b-PLA) copolymer to improve drug solubility. Micellar formulations were found to result in at least 60-fold increase in the aqueous solubility of bicalutamide and embelin. Tumor growth was also effectively regressed upon treatment with bicalutamide, but the extent of tumor regression was significantly higher when bicalutamide was formulated in micelles. To further improve bicalutamide aqueous solubility, a series of novel biodegradable copolymers for the systematic micellar delivery of bicalutamide was designed and synthesized. Flory-Huggins interaction parameter (χFH) was used to assess compatibility between bicalutamide and poly (L-lactide) or poly (carbonate-co-lactide) polymer pairs.

    Forty-five patients with relapsed or refractory multiple myeloma received continuous infusions of vincristine (0.4 mg total dose daily for 4 days) and adriamycin (9 mg m-2 daily for 4 days) with a high dose of methylprednisolone (1 g m-2 i.v. or p.o. daily by 1 h infusion), the VAMP regimen. Sixteen (36%) responded, with a median duration of remission of 11 months and median survival of 20 months. Major toxicities encountered were infective and cardiovascular. Two smaller groups of myeloma patients were treated with high dose methylprednisolone (HDMP) alone, or VAMP plus weekly low dose cyclophosphamide (Cyclo-VAMP). HDMP produced short responses in 25% of patients with less toxicity than VAMP. Cyclo-VAMP was used in a highly selected group of patients who had previously responded to high dose melphalan. It was well tolerated and produced responses in 61% of this group. PMID:3207601

    Of 1,203 patients who received radiation treatment for acne vulgaris between 1940 and 1968, 302 patients were recalled and examined, 121 at Geisinger Medical Center and the remainder by their local physicians. Radiation records were reviewed on all patients. Lead-rubber and cones had been used as shielding. Mean age at the time of exposure was 21 years and mean total exposure was 692 R. Palpable nodular thyroid disease was found in eight patients (2.6%). Of these, thyroid carcinoma was detected in two patients (0.66%). Although the number of patients examined was small, the incidence of carcinomas was unexpectedly high. We conclude that follow-up examination is worthwhile for patients previously treated by irradiation for acne vulgaris.

    Full Text Available We present the case of a 40-year-old man with previously treated thymic carcinoma, complaining of gradually worsening back pain. Computed tomography scans of the chest showed multiple pleural disseminated nodules with a pleural effusion in the right thorax. The patient was treated with carboplatin on day 1 plus nab-paclitaxel on day 1 and 8 in cycles repeated every 4 weeks. Objective tumor shrinkage was observed after 4 cycles of this regimen. In addition, the elevated serum cytokeratin 19 fragment level decreased, and the patient's back pain was relieved without any analgesics. Although he experienced grade 4 neutropenia and granulocyte colony-stimulating factor (G-CSF injection, the severity of thrombocytopenia and nonhematological toxicities such as reversible neuropathy did not exceed grade 1 during the treatment. To our knowledge, this is the first report to demonstrate the efficacy of combination chemotherapy consisting of carboplatin and nab-paclitaxel against thymic carcinoma. This case report suggests that nab-paclitaxel in combination with carboplatin can be a favorable chemotherapy regimen for advanced thymic carcinoma.

    2007-09-15

    Purpose: To evaluate the palliative effect of endobronchial brachytherapy (EBB) for patients with lung cancer that previously received external beam radiotherapy (EBRT). Materials and Methods: From July 1992 to May 2003, 29 patients with a recurrent or persistent lung cancer were treated with palliative EBB at our institute. EBB consisted of three fractions (once a week) of a dose of 5 Gy using the high dose-rate remote after loader. Symptomatic improvement was assessed subjectively, and patients were divided into two groups according to whether symptoms were improved or not. Factors such as age, performance status, duration from EBRT to EBB and the location of the tumor were compared between the improved and unimproved groups of patients. Results: Overall symptomatic improvement was found in 27 out of 52 symptoms (52%). Improvement as to the type of symptoms was seen in 41%, 50%, 82% and 33% of patients with cough, dyspnea, hemoptysis, and obstructive pneumonia respectively. The rate of improvement of hemoptysis was more than that of cough (p < 0.05). The median time to symptom relapse was 5 months. The improved patient group (n=17, 59%) had a better performance status and longer duration from EBRT to EBB than the unimproved patient group (p < 0.05). Lesions located in the distal trachea and/or main bronchus were found more frequently in the improved group of patients than in the unimproved group of patients, but the difference was not statistically significant (p =0.06). Fatal complications developed in two patients (7%), which were a hemoptysis and bronchopleural fistula respectively. Conclusion: Symptom improvement was found in 60% of patients after EBB and improvement was maintained for 5 months. Palliative EBB, even when EBRT was given previously, can be effective for a patient that has an endobronchial symptom, such as hemoptysis, and for a patient with good performance and a long duration from previous EBRT to EBB.

    Purpose: To determine the incidence of and risk factors for radiation pneumonitis (RP) after stereotactic ablative radiation therapy (SABR) to the lung in patients who had previously undergone conventional thoracic radiation therapy. Methods and Materials: Seventy-two patients who had previously received conventionally fractionated radiation therapy to the thorax were treated with SABR (50 Gy in 4 fractions) for recurrent disease or secondary parenchymal lung cancer (T <4 cm, N0, M0, or Mx). Severe (grade {>=}3) RP and potential predictive factors were analyzed by univariate and multivariate logistic regression analyses. A scoring system was established to predict the risk of RP. Results: At a median follow-up time of 16 months after SABR (range, 4-56 months), 15 patients had severe RP (14 [18.9%] grade 3 and 1 [1.4%] grade 5) and 1 patient (1.4%) had a local recurrence. In univariate analyses, Eastern Cooperative Oncology Group performance status (ECOG PS) before SABR, forced expiratory volume in 1 second (FEV1), and previous planning target volume (PTV) location were associated with the incidence of severe RP. The V{sub 10} and mean lung dose (MLD) of the previous plan and the V{sub 10}-V{sub 40} and MLD of the composite plan were also related to RP. Multivariate analysis revealed that ECOG PS scores of 2-3 before SABR (P=.009), FEV1 {<=}65% before SABR (P=.012), V{sub 20} {>=}30% of the composite plan (P=.021), and an initial PTV in the bilateral mediastinum (P=.025) were all associated with RP. Conclusions: We found that severe RP was relatively common, occurring in 20.8% of patients, and could be predicted by an ECOG PS score of 2-3, an FEV1 {<=}65%, a previous PTV spanning the bilateral mediastinum, and V{sub 20} {>=}30% on composite (previous RT+SABR) plans. Prospective studies are needed to validate these predictors and the scoring system on which they are based.

    Cetuximab is a monoclonal antibody against epidermal growth factor receptor useful in the treatment of patients with Head and Neck Squamous Cell Carcinoma combined with radiotherapy or chemotherapy. Its pharmacokinetics are not influenced by hepatic status and there are no specific warnings concerning its indication in patients with impaired hepatic function. Patients with a previous liver transplant are at risk for hepatic toxicity and use immunosupressants to avoid rejection that can interact with other drugs. We present two cases of patients with a previous liver transplant in which cetuximab was administered to treat head and neck cancer.

    Full Text Available Purpose: Women with human papilloma virus (HPV associated cervical neoplasia have a higher risk of developing breast cancer than the general female population. The purpose of this study was to (i identify high risk for cancer HPVs in cervical neoplasia and subsequent HPV positive breast cancers which developed in the same patients and (ii determine if these HPVs were biologically active.Methods: A range of polymerase chain reaction (PCR and immunohistochemical techniques were used to conduct a retrospective cohort study of cervical precancers and subsequent breast cancers in the same patients. Results: The same high risk HPV types were identified in both the cervical and breast specimens in 13 (46% of 28 patients. HPV type 18 was the most prevalent. HPVs appeared to be biologically active as demonstrated by the expression of HPV E7 proteins and the presence of HPV associated koilocytes. The average age of these patients diagnosed with breast cancer following prior cervical precancer was 51 years, as compared to 60 years for all women with breast cancer (p for difference = 0.001. Conclusions: These findings indicate that high risk HPVs can be associated with cervical neoplasia and subsequent young age breast cancer. However these associations are unusual and are a very small proportion of breast cancers. These outcomes confirm and extend the observations of 2 similar previous studies and offer one explanation for the increased prevalence of serious invasive breast cancer among young women.

    Full Text Available Abstract Background Insecticide-treated nets represent currently a key malaria control strategy, but low insecticide re-treatment rates remain problematic. Olyset™ nets are currently one of two long-lasting insecticidal nets recommended by WHO. An assessment was carried out of the effect of Olyset™ nets after seven years of use in rural Tanzania. Methods A survey of Olyset™ nets was conducted in two Tanzanian villages to examine their insecticide dosage, bioassay efficacy and desirability compared with ordinary polyester nets. Results Of 103 randomly selected nets distributed in 1994 to 1995, 100 could be traced. Most nets were in a condition likely to offer protection against mosquito biting. Villagers appreciated mainly the durability of Olyset™ nets and insecticide persistence. People disliked the small size of these nets and the light blue colour and preferred a smaller mesh size, features that can easily be modified. At equal price, 51% said they would prefer to buy an Olyset™ net and 49% opted for an ordinary polyester net. The average permethrin content was 33%-41% of the initial insecticide dose of 20,000 mg/Kg. Bioassay results indicated high knock-down rates at 60 minutes, but the mosquito mortality after 24 hours was rather low (mean: 34%. No significant correlation was found between bioassay results and insecticide concentration in and on the net. Conclusions Olyset™ nets are popular, durable and with a much longer insecticide persistence than ordinary polyester nets. Hence, Olyset™ nets are one of the best choices for ITN programmes in rural malaria-endemic areas.

    2004-12-01

    Thirty-five patients with metastatic breast cancer (MBC) entered a phase II study of pegylated liposomal doxorubicin 35 mg/m2 intravenously (i.v.) on day 1 plus vinorelbine 30 mg/m2 i.v. on day 1 every 4 weeks. Patients were required to have measurable disease, previous chemotherapy with an anthracycline-containing regimen, and a normal left ventricular ejection fraction (LVEF). Thirty-four patients were assessable for response and toxicity. The overall response rate (on an intent-to-treat basis) was 35% (12 of 34; 95% CI, 20%-54%). One complete response and 11 partial responses were noted. In addition, 14 patients (41%) had stable disease of > 4 months duration, and 7 patients (20.5%) had disease progression. The response rates to the combination when it was used as first- and second-line chemotherapy were 31% (4 of 13) and 38% (8 of 21), respectively. Median time to disease progression was 7 months (range, 1-35 months) and median overall survival was 13 months (range, 2 to > 62 months). Neutropenia was the most frequent toxicity (grade 4 in 44% of patients and 19% of cycles), but neutropenic fever was seen in only 3 cases. No septic deaths occurred. Nonhematologic grade 3 side effects included skin toxicity (palmar-plantar erythrodysesthesia syndrome, 6%) and mucositis (15%). Late alopecia was seen in 53% of patients (grade 1 in 41%, and grade 2 in 12%). The median LVEFs were 64% (range, 50%-81%) at baseline and 62% (range, 37%-70%) after treatment. Three patients presented an LVEF decrease to < 50%; however, no clinical heart failure was noted, and 2 of these patients recovered normal values after cessation of therapy. The combination of pegylated liposomal doxorubicin and vinorelbine can be safely administered to patients with anthracycline-pretreated MBC and is active in this population.

    Full Text Available TB is one of the main health priorities in Uzbekistan and relatively high rates of unfavorable treatment outcomes have recently been reported. This requires closer analysis to explain the reasons and recommend interventions to improve the situation. Thus, by using countrywide data this study sought to determine trends in unfavorable outcomes (lost-to-follow-ups, deaths and treatment failures and describe their associations with socio-demographic and clinical factors.A countrywide retrospective cohort study of all new and previously treated TB patients registered in the National Tuberculosis programme between January 2006 and December 2010.Among 107,380 registered patients, 67% were adults, with smaller proportions of children (10%, adolescents (4% and elderly patients (19%. Sixty per cent were male, 66% lived in rural areas, 1% were HIV-infected and 1% had a history of imprisonment. Pulmonary TB (PTB was present in 77%, of which 43% were smear-positive and 53% were smear-negative. Overall, 83% of patients were successfully treated, 6% died, 6% were lost-to-follow-up, 3% failed treatment and 2% transferred out. Factors associated with death included being above 55 years of age, HIV-positive, sputum smear positive, previously treated, jobless and living in certain provinces. Factors associated with lost-to-follow-up were being male, previously treated, jobless, living in an urban area, and living in certain provinces. Having smear-positive PTB, being an adolescent, being urban population, being HIV-negative, previously treated, jobless and residing in particular provinces were associated with treatment failure.Overall, 83% treatment success rate was achieved. However, our study findings highlight the need to improve TB services for certain vulnerable groups and in specific areas of the country. They also emphasize the need to develop unified monitoring and evaluation tools for drug-susceptible and drug-resistant TB, and call for better TB

    Compared to the general population, the risk of developing non-melanoma skin cancer is considerably higher among individuals with a previous history of this condition. Protection from ultraviolet (UV) radiation is the primary evidence-based approach for minimizing this risk. This review was aimed to assess the prevalence of sun-safe behaviors in non-melanoma skin cancer survivors. Searches were conducted in six electronic databases including PubMed, Psyclnfo, CINAHL, EMBASE, ERIC and Science Direct. A narrative approach was adopted to synthesize the data. The findings demonstrated that respondents do not protect themselves optimally from UV radiation exposure. Low levels of perceived skin cancer risk, a lack of knowledge about effective sun protection strategies and the inconvenience associated with sun-safe behaviors appear to explain this finding. A note of caution is required here, as there is a potential for publication bias. Moreover, the results of this study cannot be generalized to all non-melanoma skin cancer patients. Skin cancer survivors must be educated about their increased risk of future skin cancers. Behavioral interventions must be developed to increase the adoption of skin protective behaviors in this high-risk population group.

    microRNA expression signatures can differentiate normal and breast cancer tissues and can define specific clinico-pathological phenotypes in breast tumors. In order to further evaluate the microRNA expression profile in breast cancer, we analyzed the expression of 667 microRNAs in 29 tumors and 21 adjacent normal tissues using TaqMan Low-density arrays. 130 miRNAs showed significant differential expression (adjusted P value = 0.05, Fold Change = 2) in breast tumors compared to the normal adjacent tissue. Importantly, the role of 43 of these microRNAs has not been previously reported in breast cancer, including several evolutionary conserved microRNA*, showing similar expression rates to that of their corresponding leading strand. The expression of 14 microRNAs was replicated in an independent set of 55 tumors. Bioinformatic analysis of mRNA targets of the altered miRNAs, identified oncogenes like ERBB2, YY1, several MAP kinases, and known tumor-suppressors like FOXA1 and SMAD4. Pathway analysis identified that some biological process which are important in breast carcinogenesis are affected by the altered microRNA expression, including signaling through MAP kinases and TP53 pathways, as well as biological processes like cell death and communication, focal adhesion and ERBB2-ERBB3 signaling. Our data identified the altered expression of several microRNAs whose aberrant expression might have an important impact on cancer-related cellular pathways and whose role in breast cancer has not been previously described.

    Endotracheal/endobronchial metastasis, which is from either primary bronchogenic carcinoma or a tumor of non-pulmonary origin, is a rare but life-threatening condition. Among the different locations in the tracheobronchial tree, the trachea is an extremely rare location for metastasis from extrapulmonary tumor. To the best of our knowledge, endotracheal metastasis that was clearly visualized by F-18 FDG PET/CT has not been previously reported. We herein report on a patient with a FDG-avid endotracheal eccentric mass that was confirmed as metastasis from rectal cancer

    Periodic drug resistance surveillance provides useful information on trends of drug resistance and effectiveness of tuberculosis (TB) control measures. The present study determines the prevalence of drug resistance among new sputum smear positive (NSP) and previously treated (PT) pulmonary TB patients, diagnosed at public sector designated microscopy centers (DMCs) in the state of Tamil Nadu, India. In this single-stage cluster-sampling prevalence survey, 70 of 700 DMCs were randomly selected using a probability-proportional to size method. A cluster size of 24 for NSP and a varying size of 0 to 99 for PT cases were fixed for each selected DMC. Culture and drug susceptibility testing was done on Lowenstein-Jensen medium using the economic variant of proportion sensitivity test for isoniazid (INH), rifampicin (RMP), ofloxacin (OFX) and kanamycin (KAN). Human Immunodeficiency Virus (HIV) status was collected from patient records. From June 2011 to August 2012, 1524 NSP and 901 PT patients were enrolled. Any RMP resistance and any INH resistance were observed in 2.6% and 15.1%, and in 10.4% and 30% respectively in NSP and PT cases. Among PT patients, multi drug resistant TB (MDR-TB) was highest in the treatment failure (35%) group, followed by relapse (13%) and treatment after default (10%) groups. Extensively drug resistant TB (XDRTB) was seen in 4.3% of MDR-TB cases. Any OFX resistance was seen in 10.4% of NSP, 13.9% of PT and 29% of PT MDR-TB patients. The HIV status of the patient had no impact on drug resistance levels. RMP resistance was present in 2.6% of new and 15.1% of previously treated patients in Tamil Nadu. Rates of OFX resistance were high among NSP and PT patients, especially among those with MDR-TB, a matter of concern for development of new treatment regimens for TB.

    To present our experience in the therapeutic approach of the sentinel node biopsy (SNB) in patients with previous excision of the breast cancer, divided in non-palpable and palpable lesions, in comparison with time treatment and stagement of breast cancer. In the period 2001-2006, 138 patients with prior diagnostic excisional biopsy (96 non-palpable and 42 palpable breast cancer) and 328 without previous surgery (32 non-palpable; 296 palpable cancer) were treated. The combined technique ({sup 99m}Tc-colloidal rhenium and isosulfan blue dye) was the approach for sentinel lymph node (SLN) detection. Axillary lymph node dissection (ALND) was completed only when the SLN was positive for metastasis or not located. Detection rate, if there was prior surgery, was 95% for non-palpable and 98% for palpable cancer, and 99% for one-time treatment group. Metastasis rate in the SLN was 15% in non-palpable cancer (14/91), significantly smaller than in palpable breast cancer (39% if prior surgery and 37% in one-time surgery). According to tumoral size, ALND metastasis rate was similar for T1 and T2 tumors (43-44%). In the follow-up of the groups with prior diagnostic biopsy or surgery of the breast cancer we have not found any false negative in the axilla. The detection of the SLN is also feasible in patients with previous surgery of breast cancer. Because SLN metastasis rates are significantly smaller in non-palpable lesions, the effort in screening programs for early detection of breast cancer and also in improving histopathological confirmation of malignancy with ultrasound or stereotactic guided core biopsies must continue.

    Our study aimed to describe safety and neurological impact of alemtuzumab as last-line rescue therapy in aggressive multiple sclerosis (MS) patients, previously treated by Mitoxantrone (MITOX). Between June 2004 and October 2013, 13 patients received alemtuzumab at 20 mg/day and 3 at 12 mg/day for 5 days. EDSS, relapses, secondary progression were prospectively assessed 12 and 6 months before treatment, at baseline and every 3 months. Mean follow-up was 6.2 years [1-10]. Mean age at alemtuzumab start was 40 years [26-49] for 8 Secondary Progressive (SP) and 30 years [26-35] for 8 Relapsing-Remitting (RR) patients. MS duration was 13.7 (± 3) and 8.3 (± 4) years, respectively. During the 12 months before alemtuzumab, annual relapse rate was 0.75 and 3.14, respectively and the 16 patients accumulated 2-30 new gadolinium enhancing lesions. 4 patients (suboptimal responders) received alemtuzumab during MITOX and 12 patients 1-7.8 years after MITOX. Out of 8 SPMS, 2 were disease free up to last visit (4.7 and 8 years), 5 improved or stabilized but only transiently and 1 worsened. Out of 8 RRMS, 1 remained stable up to last visit (8.7 years) despite 1 relapse and active MRI at 18 months and 7 improved (1-4 point EDSS): 4 remained disease free up to last visit (12, 24, 38 months and 7 years), 2 were successfully retreated at 25 and 33 months and 1 worsened progressively 24 months after alemtuzumab. 2 patients developed Grave's disease and 1 hypothyroidism. Alemtuzumab controls aggressive RRMS despite previous use of MITOX.

    Full Text Available Abstract Background Colorectal cancer (CRC is the second leading cause of cancer death in developed countries. Familial aggregation in CRC is also important outside syndromic forms and, in this case, a polygenic model with several common low-penetrance alleles contributing to CRC genetic predisposition could be hypothesized. Mucins and GALNTs (N-acetylgalactosaminyltransferase are interesting candidates for CRC genetic susceptibility and have not been previously evaluated. We present results for ten genetic variants linked to CRC risk in previous studies (previously identified category and 18 selected variants from the mucin gene family in a case-control association study from the Spanish EPICOLON consortium. Methods CRC cases and matched controls were from EPICOLON, a prospective, multicenter, nationwide Spanish initiative, comprised of two independent stages. Stage 1 corresponded to 515 CRC cases and 515 controls, whereas stage 2 consisted of 901 CRC cases and 909 controls. Also, an independent cohort of 549 CRC cases and 599 controls outside EPICOLON was available for additional replication. Genotyping was performed for ten previously identified SNPs in ADH1C, APC, CCDN1, IL6, IL8, IRS1, MTHFR, PPARG, VDR and ARL11, and 18 selected variants in the mucin gene family. Results None of the 28 SNPs analyzed in our study was found to be associated with CRC risk. Although four SNPs were significant with a P-value ADH1C (OR = 1.63, 95% CI = 1.06-2.50, P-value = 0.02, recessive, rs1800795 in IL6 (OR = 1.62, 95% CI = 1.10-2.37, P-value = 0.01, recessive, rs3803185 in ARL11 (OR = 1.58, 95% CI = 1.17-2.15, P-value = 0.007, codominant, and rs2102302 in GALNTL2 (OR = 1.20, 95% CI = 1.00-1.44, P-value = 0.04, log-additive 0, 1, 2 alleles], only rs3803185 achieved statistical significance in EPICOLON stage 2 (OR = 1.34, 95% CI = 1.06-1.69, P-value = 0.01, recessive. In the joint analysis for both stages, results were only significant for rs3803185 (OR = 1

    Microsatellite instability (MSI) is a tumor phenotype linked to somatic or germline (Lynch syndrome) inactivating alterations of DNA mismatch repair genes. A broad spectrum of neoplasms exhibits MSI phenotype, mainly colorectal cancer, endometrial cancer, and gastric cancer. MSI tumors are characterized by dense immune infiltration and high load of tumor neo-antigens. Growing evidence is accumulating on the efficacy of immune checkpoint inhibition for patients treated for MSI solid tumors. We present a comprehensive overview of MSI phenotype, its biological landscape and current diagnostic methods. Then we focus on MSI as a predictive biomarker of response to immune checkpoint inhibition in the context of colorectal cancer and non-colorectal tumors.

    In their paper "Intratumoral injection of Clostridium novyi-NT spores induces antitumor responses", Roberts et al. describe the induction of antitumor responses following local spore administration of an attenuated C. novyi strain (C. novyi-NT). Stereotactic intratumoral spore injection led to significant survival advantages in a murine orthotopic brain model and local bacterial treatment produced robust responses in a set of spontaneous canine soft tissue carcinomas. Their preclinical findings in both models, provided the basis for a phase 1 investigational clinical study in patients with solid tumors that were either refractory to standard treatment or without an available standard treatment available (NCT01924689). The results of the first patient enrolled in this trial, a 53-year-old female with a retroperitoneal leiomyosarcoma, are described. Next to the non-armed C. novyi-NT described in this paper, very potent genetically modified Clostridium expressing anti-cancer therapeutic genes are also being developed. Are treatments with these non-pathogenic clostridia a viable alternative cancer treatment?

  9. Considering GH replacement for GH-deficient adults with a previous history of cancer: a conundrum for the clinician.

    Science.gov (United States)

    Yuen, Kevin C J; Heaney, Anthony P; Popovic, Vera

    2016-05-01

    Previous studies have shown that GH and IGF-I may enhance tumorigenesis, metastasis, and cell proliferation in humans and animals. Evidence supporting this notion is derived from animal model studies, epidemiological studies, experience from patients with acromegaly, molecular therapeutic manipulation of GH and IGF-I actions, and individuals with GH receptor and congenital IGF-I deficiencies. Prior exposure to radiation therapy, aging, family history of cancer, and individual susceptibility may also contribute to increase this risk. Therefore, the use of GH replacement in patients with a history of cancer raises hypothetical safety concerns for patients, caregivers, and providers. Studies of GH therapy in GH-deficient adults with hypopituitarism and childhood cancer survivors have not convincingly demonstrated an increased cancer risk. Conversely, the risk of occurrence of a second neoplasm (SN) in childhood cancer survivors may be increased, with meningiomas being the most common tumor; however, this risk appears to decline over time. In light of these findings, if GH replacement is to be considered in patients with a previous history of cancer, we propose this consideration to be based on each individual circumstance and that such therapy should only be initiated at least 2 years after cancer remission is achieved with the understanding that in some patients (particularly those with childhood cancers), GH may potentially increase the risk of SNs. In addition, close surveillance should be undertaken working closely with the patient's oncologist. More long-term data are thus needed to determine if GH replacement in GH-deficient adults with a history of cancer is associated with the development of de novo tumors and tumor recurrence.

    Full Text Available Abstract Background A better understanding of the relationship between treatment-seeking for alcohol problems and personality traits could give useful insight in factors promoting or hindering treatment for alcohol use disorders (AUD. The aim of this study was to analyze the associations between treatment-seeking for AUD, personality traits, and psychiatric co-morbidity in women. The study was based on pooled cross-sectional data from three population based samples and one clinical sample (n = 1,339. Comparisons were made between treated and untreated women with AUD, and between those with resolved and unresolved AUD. Results A stepwise logistic regression model showed that treatment-seeking for AUD was not associated with personality traits. Among women with lifetime AUD (n = 217, those who had been treated (n = 42 had significantly higher scores than untreated women (n = 175 on three personality traits of the Karolinska Scales of Personality (KSP; somatic anxiety, muscular tension, and guilt. Women with resolved AUD, who had received treatment (n = 23 had significantly higher scores on scales measuring somatic anxiety, psychic anxiety, muscular tension, irritability, and guilt than untreated women with resolved AUD. The latter group resembled women without AUD on most personality traits. There were no differences in occurrence of lifetime psychiatric disorders between the treated and the untreated women, whereas treated women with current AUD had increased risk of lifetime anxiety (OR: 3.1, 95% CI: 1.1–8.7. Conclusion Treatment-seeking was not associated with personality traits in this study. Still, it can be concluded that women with resolved AUD who had received treatment had high scores on the KSP-scales measuring psychic and somatic anxiety, tension, irritability, and feelings of guilt. This suggests that personality assessment might be a useful tool in tailoring individual treatment programs for women with AUD. Future studies need to

    Full Text Available Oral cancer is one of the usual causes of mortality all over the world, with a five-year survival rate of only 50%. Oral cancers are treated primarily by surgery with / without adjuvant radiotherapy and / or chemotherapy. However, there is significant post-treatment morbidity and mortality secondary to recurrences. Dietary supplements like fruits and vegetables are rich in phytochemicals and provide a variety of antioxidants like vitamin A, C, E. Spirulina, Selenium, Green tea (EGCG, Neem, Tomatoes (lycopene, Turmeric (curcumin, and some medicinal mushrooms are also used as chemopreventive and chemotherapeutic agents. This overview emphasizes on natural therapies to fight against oral cancer. Thus, there are several natural compounds that can enhance the prevention of oral cancer.

    Directory of Open Access Journals (Sweden)

    Prajapati P M.

    2012-06-01

    Full Text Available Gene therapy is the process of introducing genetic material RNA or DNA into a person's cells to fight disease. Gene therapy treats disease by either replacing damaged or missing genes with normal ones, or by providing new genes. The concept of gene therapy was born more than thirty years ago; however, new technology is opening the door to dramatically new possibilities in the treatment of cancers of all kinds. The long-term goal of cancer gene therapy is to develop treatments that attack only cancer cells, thereby eliminating adverse effects on the body and improving the possibility to cure disease. Gene therapy may someday soon make cancer a manageable disease with nominal side effects to the patients. Furthermore, since gene therapy has potential for other diseases such as cystic fibrosis, hemophilia, sickle-cell anemia, muscular dystrophy and Parkinson's, the value of research and discovery has broad applications.

    Anterior-predominant prostate cancer (APC) is an incompletely understood entity which can be difficult to sample via transrectal biopsy. Seemingly favorable biopsy results may belie the potential aggressiveness of these tumors. Here, we attempt to characterize APC by retrospectively examining the clinicopathologic features of APC at radical prostatectomy and comparing our findings with prior biopsy information. We found that 17.4 % of patients in our study had APC. APC demonstrated a significantly lower (P value biopsy than non-transperineal saturation (i.e., transrectal ultrasound guided) biopsy strategies. Four patients (7 %) without transperineal saturation biopsy exhibited a significantly worse GS at RP than biopsy, compared to five patients (36 %) with transperineal saturation biopsy. Our findings corroborate the difficulty in detecting APC and suggest that APC is not a uniform disease with a wholly indolent phenotype. Dedicated long-term outcome data are needed in these patients. Additionally, alternative pathologic staging parameters may be necessary.

    Full Text Available Abstract Background Attention-deficit/hyperactivity disorder (ADHD is a common neurobehavioral psychiatric disorder that afflicts children, with a reported prevalence of 2.4% to 19.8% worldwide. Stimulants (methylphenidate [MPH] and amphetamine are considered first-line ADHD pharmacotherapy. MPH is a catecholamine reuptake inhibitor, whereas amphetamines have additional presynaptic activity. Although MPH and amphetamine can effectively manage ADHD symptoms in most pediatric patients, many still fail to respond optimally to either. After administration, the prodrug stimulant lisdexamfetamine dimesylate (LDX is converted to l-lysine and therapeutically active d-amphetamine in the blood. The objective of this study was to evaluate the clinical efficacy of LDX in children with ADHD who remained symptomatic (ie, nonremitters; ADHD Rating Scale IV [ADHD-RS-IV] total score > 18 on MPH therapy prior to enrollment in a 4-week placebo-controlled LDX trial, compared with the overall population. Methods In this post hoc analysis of data from a multicenter, randomized, double-blind, forced-dose titration study, we evaluated the clinical efficacy of LDX in children aged 6-12 years with and without prior MPH treatment at screening. ADHD symptoms were assessed using the ADHD-RS-IV scale, Conners' Parent Rating Scale-Revised short form (CPRS-R, and Clinical Global Impressions-Improvement scale, at screening, baseline, and endpoint. ADHD-RS-IV total and CPRS-R ADHD Index scores were summarized as mean (SD. Clinical response for the subgroup analysis was defined as a ≥ 30% reduction from baseline in ADHD-RS-IV score and a CGI-I score of 1 or 2. Dunnett test was used to compare change from baseline in all groups. Number needed to treat to achieve one clinical responder or one symptomatic remitter was calculated as the reciprocal of the difference in their proportions on active treatment and placebo at endpoint.

    2011-09-01

    Full Text Available There are many genes which are responsible for developing breast cancer especially, BRCA2 (Breast Cancer 2 and HER2 are extensively involved in developing breast cancer and hence it is the centre of attractions for all the researchers. Nano-particles conjugated with the anti-HER2 monoclonal antibodies are called as “Trastazumab” which directly target the HER2 gene. The major advantage of this technology is that the cells can be prevented before they evolve in to mature stages i.e. metastases production. The BRCA2 gene belongs to the family of tumor suppressor genes and its protein product is responsible for the error free repair mechanisms of DNA. This BRCA2 gene interacts with RAD51 gene to fix the DNA breaks. Mutation in BRCA2 gene such as insertion and deletion leads to breast cancer. More than 800 mutations are found in this gene that lead to increased risk of the breast cancer. Furthermore, BRCA2 gene is also associated with various cancers like prostate, ovarian, fallopian, male breast cancer. Researchers believe that altered products produced due to defects in this gene are unable to interact with the gene RAD51 and cannot repair the DNA. Antisense RNA is the tool which can used to block any RNA or DNA to synthesize its product. In this review we focus in using Antisense RNA against the sense RNA of an altered BRCA2 gene to block the altered affectivity of that gene on the DNA repair mechanism. However, Antisense RNA technique may not help in treating breast cancer, it can better manage the breast cancer to occur.

    Full Text Available Introduction: Nucleoside reverse transcriptase inhibitor (NRTI is associated with endothelial dysfunction and proinflammatory effects. Maraviroc (MVC is an antagonist of CCR5 receptor. CCR5 is the receptor of RANTES (Regulated on Activation, Normal T Cell Expressed and Secreted, a mediator of chronic inflammation and endothelial function. Our aim was to evaluate the maintenance of viral suppression and improvement of endothelial function in virologically suppressed HIV-infected patients switched to an NRTI-sparing combined antiretroviral therapy (cART with MVC. Materials and Methods: This observational, non-interventional, multicenter study was performed at the Infectious Diseases Service of Santa Lucia, Morales Meseguer, Virgen de la Arrixaca and Reina Sofía University Hospital (Murcia, Spain.

    Full Text Available Abstract Background A population of breast cancer patients exists who, for various reasons, never received adjuvant post-operative tamoxifen (TAM. This study was aimed to evaluate the role of late TAM in these patients. Methods From 1997 to 2003, patients aged 35 to 75 years, operated more than 2 years previously for monolateral breast cancer without adjuvant TAM, with no signs of metastases and no contraindication to TAM were randomized to TAM 20 mg/day orally for 2 years or follow-up alone. Events were categorized as locoregional relapse, distant metastases, metachronous breast cancer, tumours other than breast cancer and death from any causes, whichever occurred first. The sample size (197 patients per arm, plus 10% allowance was based on the assumption of a 30% decrease in the number of events occurring at a rate of 5% annually in the 10 years following randomization. Four hundred and thirty-three patients were randomized in the study (TAM 217, follow-up 216. Patients characteristics (TAM/follow-up included: median age 55/55 years, median time from surgery 25/25 months (range, 25-288/25-294, in situ carcinoma 18/24, oestrogen receptor (ER positive in 75/68, negative in 70/57, unknown in 72/91 patients. Previous adjuvant treatment included chemotherapy in 131/120 and an LHRH analogue in 11/13 patients. Results Thirty-six patients prematurely discontinued TAM after a median of 1 month, mostly because of subjective intolerance. Eighty-three events (TAM 39, follow-up 44 occurred: locoregional relapse in 10/8, distant metastases in 14/16, metachronous breast cancer in 4/10, other tumours in 11/10 patients. Less ER-positive secondary breast cancers occurred in the TAM treated patients than in follow-up patients (1 vs 10, p = 0.005. Event-free survival was similar in both groups of patients. Conclusions This 5-year analysis revealed significantly less metachronous ER-positive breast cancers in the TAM treated patients. No other statistically

    Full Text Available Abstract Background Multidrug resistant tuberculosis (MDR-TB is a serious public health problem in Nepal. It is a major obstacle for the control of the tuberculosis. The main objectives of this study were to determine the prevalence of the multidrug resistant pulmonary tuberculosis and to evaluate the drug susceptibility patterns of Mycobacterium tuberculosis isolated from previously treated and newly diagnosed cases of pulmonary tuberculosis. Methods A cross-sectional study was conducted from March 2013 to August 2013 at German-Nepal tuberculosis project (GENETUP laboratory, Kathmandu, Nepal. For this the sputum samples from total of 153 (49 new and 104 previously treated suspected pulmonary tuberculosis patients were used. The diagnosis of the tuberculosis was performed by using fluorescent microscopy and culture, while the drug susceptibility testing of Mycobacterium tuberculosis was performed by proportion method. Lowenstein-Jensen (L-J medium was used for the culture of Mycobacterium tuberculosis and the colonies grown were identified on the basis of the colony morphology, pigment production and biochemical characteristics. Results The prevalence of MDR-TB among all the cases of culture positive pulmonary tuberculosis was 15.6 %. The rate of MDR-TB among previously treated culture positive tuberculosis patients was 19.4 % and that among newly diagnosed culture positive pulmonary tuberculosis cases was 7.1 %. The highest rate of resistance of Mycobacterium tuberculosis, was toward streptomycin (24.4 % followed by isoniazid (23 %, rifampicin (17.8 % and ethambutol (15.6 %. Among the total of MDR-TB cases among previously treated patients, highest percentage of the cases were relapse (61.1 % followed by chronic (16.7 %. Conclusions The high prevalence of DR/MDR-TB in our study reflects poor implementation of tuberculosis control program. On the basis of the drug susceptibility patterns of M. tuberculosis we found in our study, we

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

    Background: Platinum-based therapy (PBT) is the standard therapy for recurrent and/or metastatic head and neck cancer (HNC), but the incidence of recurrence remains high. This study evaluates the efficacy and tolerability of capecitabine as palliative monotherapy for recurrent HNC previously treated with PBT. Methods: Patients aged 18–75 years, with Eastern Cooperative Oncology Group performance status 0–2, squamous HNC with locoregional and/or metastatic recurrence previously treated with PBT and adequate organ functions, were included. Capecitabine (1.250 mg m−2 BID) was administered on days 1–14 every 21 days for at least two cycles. Results: A total of 40 male patients with a median age of 58 years were analysed. All patients received a median number of four cycles of capecitabine (range: 1–9) and the median relative dose intensity was 91%. Seven patients were not evaluable for response. Overall response rate was 24.2%. Median time to progression and overall survival were 4.8 and 7.3 months, respectively. Haematological adverse events (AEs) grade 3/4 were reported in six patients. Most common grade 3/4 non-haematological AEs were asthenia (12.5%), palmar-plantar eritrodisestesia (10%), mucositis (10%), dysphagia (10%) and diarrhoea (7.5%). Conclusions: Capecitabine seems to be an active, feasible and well-tolerated mode of palliative treatment for advanced HNC patients who have previously received PBT schedules. PMID:20485287

    Purpose To evaluate, using subgroup analysis, the effect of treatment status on the intraocular pressure (IOP)-lowering efficacy of a preservative-free formulation of fixed-combination bimatoprost 0.03%/timolol 0.5% (FCBT PF). Methods A primary, multicenter, randomized, double-masked, 12-week study compared the efficacy and safety of FCBT PF with preserved FCBT (Ganfort®) in 561 patients diagnosed with glaucoma or ocular hypertension. For this analysis, eligible patients were treatment-naïve or had inadequate IOP lowering and underwent a washout of previous treatment. IOP (8 am, 10 am, and 4 pm) was measured at baseline and weeks 2, 6, and 12. Subgroup analysis of the FCBT PF arm assessed changes in average eye IOP from baseline in treatment-naïve vs previously treated patients. To evaluate the effect of treatment status at baseline (treatment-naïve vs previously treated) on IOP reduction in the FCBT PF treatment group, an analysis of covariance model was used with treatment status and investigator as fixed effects, and baseline average eye IOP, age, glaucoma diagnosis, and baseline average eye corneal thickness as covariates. P-values and the 95% confidence intervals were determined using the model. Results In the FCBT PF arm, IOP mean changes from baseline ranged from −8.7 mmHg to −9.8 mmHg in treatment-naïve patients (N=50), compared with −7.3 mmHg to −8.5 mmHg in previously treated patients (N=228). Baseline IOP, age, glaucoma diagnosis, and corneal thickness significantly affected IOP reduction in the FCBT PF group. Adjusting for these covariates, FCBT PF had a greater IOP-lowering effect (0.8–1.7 mmHg) in treatment-naïve patients than previously treated patients, which was statistically significant (P≤0.05) at seven of nine time points. Conclusion In this subgroup analysis, FCBT PF reduced IOP more effectively in treatment-naïve than in previously treated patients possibly due, in part, to altered responsiveness or tachyphylaxis that has

    Full Text Available Celestia S Higano Department of Medicine, University of Washington, and Fred Hutchinson Cancer Research Center, Seattle, WA, USA Abstract: Over the last few years, five agents have demonstrated a survival benefit over a comparator treatment or placebo in the treatment of metastatic castration-resistant prostate cancer and have been approved by the US Food and Drug Administration: sipuleucel-T (a dendritic cell immunotherapy; cabazitaxel; abiraterone acetate and enzalutamide (both hormonal agents; and radium 223 (an alpha emitter. The development of these agents pivoted on whether patients had been treated with docetaxel, which remains the first-line chemotherapy of choice. To date, no combination of docetaxel and another active agent has demonstrated superiority to docetaxel alone despite numerous Phase III trials. Clusterin is a cytoprotective chaperone protein that is upregulated in response to various anticancer therapies. When overexpressed, clusterin interferes with apoptotic signaling, thereby promoting cell survival and conferring broad-spectrum resistance in cancer cell lines. Custirsen (OGX-011 is a second-generation 2´-methoxyethyl modified phosphorothioate antisense oligonucleotide that inhibits expression of clusterin. This review presents the preclinical and clinical data that provided the rationale for the combination of custirsen with chemotherapy in ongoing Phase III trials.

    Full Text Available The effective treatment of castrate-resistant prostate cancer (CRPC has proven to be very challenging. Until recently, docetaxel was the only therapeutic demonstrated to extend overall patient survival. Yet recently, a considerable number of new therapeutics have been approved to treat CRPC patients. These remarkable advances now give new tools for the therapeutic management of late-stage prostate cancer. In this review, we will examine mechanistic and clinical data of several newly approved therapeutics including the chemotherapeutic cabazitaxel, antiandrogen enzalutamide, endocrine disruptor abiraterone acetate, immunotherapy sipuleucel-T, and bone-targeting radiopharmaceutical alpharadin. In addition, we will examine other promising therapeutics that are currently in Phase III trials.

    Full Text Available Context Development of a second primary malignancy after an index esophageal cancer is a rare event, primarily due to short survival of patients with esophageal cancer. However, the number of long-term esophageal cancer survivors has been increasing due to advances in early detection and therapy. Case report We report herein a case of pancreatic adenocarcinoma that developed three years after a successfully treated early-stage adenocarcinoma of the esophagus. A 70-year-old Caucasian male presented with vague complaints of nausea, vomiting and abdominal distention, with subsequent development of jaundice. A computed tomography scan of abdomen revealed a 2.9 cm soft tissue mass in the head of the pancreas and the patient underwent a Whipple’s procedure, with pathology confirming the diagnosis of pancreatic adenocarcinoma. Three years previously, the patient was successfully treated for adenocarcinoma of the esophagus via minimally invasive esophagogastrectomy. Despite chemoradiotherapy for localized disease and subsequent systemic chemotherapy for metastatic pancreatic cancer, the patient eventually succumbed to his illness. Conclusion We discuss the association between esophageal cancer and subsequent second malignancies, along with implications for surveillance and therapy.

    Full Text Available Abstract Background- Data exist that demonstrate isoflavones' potent antiproliferative effects on prostate cancer cells. We evaluated the efficacy of isoflavone in patients with PSA recurrent prostate cancer after prior therapy. We postulated that isoflavone therapy would slow the rate of rise of serum PSA. Methods- Twenty patients with rising PSA after prior local therapy were enrolled in this open-labeled, Phase II, nonrandomized trial (Trial registration # NCT00596895. Patients were treated with soy milk containing 47 mg of isoflavonoid per 8 oz serving three times per day for 12 months. Serum PSA, testosterone, lipids, isoflavone levels (genistein, daidzein, and equol, and quality of life (QOL were measured at various time points from 0 to 12 months. PSA outcome was evaluated. Results- Within the mixed regression model, it was estimated that PSA had increased 56% per year before study entry and only increased 20% per year for the 12-month study period (p = 0.05. Specifically, the slope of PSA after study entry was significantly lower than that before study entry in 6 patients and the slope of PSA after study entry was significantly higher than before study entry in 2 patients. For the remaining 12 patients, the change in slope was statistically insignificant. Nearly two thirds of the patients were noted to have significant levels of free equol in their serum while on therapy. Conclusion- Dietary intervention with isoflavone supplementation may have biologic activity in men with biochemical recurrent prostate cancer as shown by a decline in the slope of PSA. This study may lend support to the literature that nutritional supplements have biologic activity in prostate cancer and therefore, further studies with these agents in randomized clinical trials should be encouraged.

    Ninety-seven patients with breast cancer recurring in a previously irradiated area (mean dose 44 Gy) were reirradiated in combination with hyperthermia and had evaluable tumor responses. In the reirradiation series, radiotherapy was given twice weekly in most patients, with a fraction size varying from 200 to 400 cGy, the total dose varying from 8 to 32 Gy. Hyperthermia was given following the radiotherapy fractions. The combined treatment resulted in 35% complete and 55% partial responses. Duration of response was median 4 months for partial response and 26 months for complete response, respectively. The median survival time for all patients was 12 months. Acute skin reaction was mild, with more than moderate erythema in only 14/97 patients. Thermal burns occurred in 44/97 patients, generally at sites where pain sensation was decreased, and therefore they did not cause much inconvenience. In the 19 patients who survived more than 2 years, no late radiation damage was observed. When patients who received a "high dose" (greater than 29 Gy and hyperthermia) were compared with those who received a "low dose" (less than 29 Gy and hyperthermia), a higher complete response rate was observed in the high dose group (58% vs. 24%), whereas no difference in acute toxicity was found. We conclude that reirradiation with 8 x 4 Gy in combination with hyperthermia twice weekly is a safe, effective and well tolerated method for palliative treatment of patients with breast cancer recurring in previously irradiated areas.

    Full Text Available Background. Phase I of this study was aimed at comparing the profiles of oxidative stress biomarkers in patients with history of nonmelanoma skin cancer (NMSC, previously treated with surgery, to the healthy subjects. Phase II aimed to evaluate the effects of supplementary antioxidant therapy on the levels of biomarkers in the case group. Materials and Methods. In Phase I, oxidative stress biomarkers were measured in blood samples obtained from 24 healthy subjects and 60 patients with history of NMSC previously treated with surgery. In Phase II, the 60 patients with history of NMSC were randomized into two subgroups, one receiving placebo (n=34 and the other (n=26 receiving vitamin C, vitamin E, and zinc supplementation for 8 weeks, followed by reevaluation of biomarkers. Results. In Phase I, patients with history of NMSC showed increased plasma concentrations of all biomarkers, but only 15-F2t-isoprostane was significantly higher than in the healthy subjects. Risk of NMSC increased by 4% for each additional 1 pg/mL increase in 15-F2t-isoprostane. In Phase II, supplementation did not significantly reduce levels of oxidative stress biomarkers. Conclusion. Patients with history of NMSC had significantly high 15-F2t-isoprostane plasma levels; supplementation did not result in significant reduction of oxidative stress biomarkers. This trial was registered with ClinicalTrials.gov (ID NCT02248584.

    Pancreatic cancer (PC) is one of the most deadly and quickly fatal human cancers with a 5-year mortality rate close to 100%. Its prognosis is very poor, mainly because of its hostile biological behavior and late onset of symptoms for clinical diagnosis; these bring limitations on therapeutic interventions. Factors contributing for the difficulties in treating PC include: high rate of drug resistance, fast metastasis to different organs, poor prognosis and relapse of the tumor after therapy. After being approved by US FDA 1997, Gemcitabine (Gem) is the first line and the gold standard drug for all stages of advanced PC till now. However, its efficacy is unsatisfactory, mainly due to; its chemical instability and poor cellular uptake, resulting in an extremely short half-life and low bioavailability. To solve this drawbacks and increase the therapeutic outcome important progress has been achieved in the field of nanotechnology and offers a promising and effective alternative. This review mainly focus on the most commonly investigated nanoparticle (NP) delivery systems of Gem for PC treatment and the latest progresses achieved. Novel nanocarriers with better tumor targeting efficiencies and maximum treatment outcome to treat this deadly due are given much attention.

    Full Text Available Gastric cancer and colorectal cancer are the leading cause of cancer mortality and have a dismal prognosis. The introduction of biological agents to treat these cancers has resulted in improved outcomes, and combination chemotherapy with targeted agents and conventional chemotherapeutic agents is regarded as standard therapy. Additional newly clarified mechanisms of oncogenesis and resistance to targeted agents require the development of new biologic agents. Aberrantly activation of the inositide signaling pathway by a loss of function PTEN mutation or gain of function mutation/amplification of PIK3CA is an oncogenic mechanism in gastric cancer and colorectal cancer. Clinical trials with biologic agents that target the inositide signaling pathway are being performed to further improve treatment outcomes of patients with advanced gastric cancer and metastatic colorectal cancer (CRC. In this review we summarize the inositide signaling pathway and introduce targeted agents that inhibit abnormal activation of this signaling pathway and clinical trials currently being performed in patients with advanced or metastatic gastric cancer and metastatic CRC using molecular target agents.

    Oligodeoxynucleotides containing CpG motifs (CpG ODN) can alter various immune cell subsets important in antibody therapy of malignancy. We undertook a phase I trial of CPG 7909 (also known as PF-3512676) in patients with previously treated lymphoma with the primary objective of evaluating safety across a range of doses, and secondary objectives of evaluating immunomodulatory effects and clinical effects. Twenty-three patients with previously treated non-Hodgkin lymphoma received up to 3 weekly 2-hour intravenous (IV) infusions of CPG ODN 7909 at dose levels 0.01 to 0.64 mg/kg. Evaluation of immunologic parameters and clinical endpoints occurred for 6 weeks. Infusion-related toxicity included grade 1 nausea, hypotension, and IV catheter discomfort. Serious adverse hematologic events observed more than once included anemia (2=Gr3, 2=Gr4), thrombocytopenia (4=Gr3), and neutropenia (2=Gr3), and were largely judged owing to progressive disease. Immunologic observations included: (1) The mean ratio of NK-cell concentrations compared with pretreatment at day 2 was 1.44 (95% CI=0.94-1.94) and at day 42 was 1.53 (95% CI=1.14-1.91); (2) NK activity generally increased in subjects; and (3) Antibody-dependent cellular cytotoxicity activity increased in select cohorts. No clinical responses were documented radiographically at day 42. Two subjects demonstrated late response. We conclude CpG 7909 can be safely given as a 2-hour IV infusion to patients with previously treated non-Hodgkin lymphoma at doses that have immunomodulatory effects.

    Full Text Available Background. Therapy for metastatic castration-resistant prostate cancer (CRPC is a serious problem that requires significant public health care expenditures.Objective: to evaluate the cost-effectiveness of abiraterone treatment in patients with metastatic CRPC who previously received docetaxel under the conditions of the budgetary public health system of the Russian Federation.Material and methods. Markovian simulation based on the COU-AA-301 randomized placebo-controlled Phase III study was used. Survival analysis was made in 70-year-old patients. The cost of abiraterone therapy corresponded to that of the 2013 auctions.Results. Abiraterone therapy in patients who have previously received docetaxel therapy causes an increase in average life expectancy by an average of 4.6 months and progression-free survival by 2.0 months. Moreover, the cost calculated with reference to one year of additional life will account for about 3.6 million rubles and that to one additional quality-adjusted life year will be about 5.45 million rubles.Conclusion. The cost-effectiveness of abiraterone therapy for metastatic CRPC in patients who have previously received docetaxel therapy is similar to that of other medicaments used in oncological practice under the conditions of the budgetary public health system of the Russian Federation. In this connection, abiraterone may be considered as an economically acceptable medical intervention in this clinical situation.

  20. Cancer Mortality in People Treated with Antidepressants before Cancer Diagnosis: A Population Based Cohort Study.

    Full Text Available Depression is common after a cancer diagnosis and is associated with an increased mortality, but it is unclear whether depression occurring before the cancer diagnosis affects cancer mortality. We aimed to study cancer mortality of people treated with antidepressants before cancer diagnosis.We conducted a population based cohort study of all adults diagnosed with cancer between January 2003 and December 2010 in Denmark (N = 201,662. We obtained information on cancer from the Danish Cancer Registry, on the day of death from the Danish Civil Registry, and on redeemed antidepressants from the Danish National Prescription Registry. Current users of antidepressants were defined as those who redeemed the latest prescription of antidepressant 0-4 months before cancer diagnosis (irrespective of earlier prescriptions, and former users as those who redeemed the latest prescription five or more months before cancer diagnosis. We estimated an all-cause one-year mortality rate ratio (MRR and a conditional five-year MRR for patients who survived the first year after cancer diagnosis and confidence interval (CI using a Cox proportional hazards regression model. Overall, 33,111 (16.4% patients redeemed at least one antidepressant prescription in the three years before cancer diagnosis of whom 21,851 (10.8% were current users at the time of cancer diagnosis. Current antidepressant users had a 32% higher one-year mortality (MRR = 1.32, 95% CI: 1.29-1.35 and a 22% higher conditional five-year mortality (MRR = 1.22, 95% CI: 1.17-1.26 if patients survived the first year after the cancer diagnosis than patients not redeeming antidepressants. The one-year mortality was particularly high for patients who initiated antidepressant treatment within four months before cancer diagnosis (MRR = 1.54, 95% CI: 1.47-1.61. Former users had no increased cancer mortality.Initiation of antidepressive treatment prior to cancer diagnosis is common and is associated with an increased

    BACKGROUND This study reports the pathogenesis of anal canal adenocarcinoma in a patient with longstanding Crohn's disease (CD). CASE REPORT A 50-year-old woman with a 33-year history of CD presented with perianal pain of several months' duration. She had been treated surgically for a rectovaginal fistula 26 years earlier and had been treated with infliximab (IFX) for the previous 4 years. A biopsy under anesthesia revealed an anal canal adenocarcinoma, which was removed by abdominoperineal resection. Pathological examination showed that a large part of the tumor consisted of mucinous adenocarcinoma at the same location as the rectovaginal fistula had been removed 26 years earlier. There was no evidence of recurrent rectovaginal fistula, but thick fibers surrounded the tumor, likely representing part of the previous rectovaginal fistula. Immunohistochemical analysis using antibodies against cytokeratins (CK20 and CK7) revealed that the adenocarcinoma arose from the rectal mucosa, not the anal glands. CONCLUSIONS Mucinous adenocarcinoma can arise in patients with CD, even in the absence of longstanding perianal disease, and may be associated with adenomatous transformation of the epithelial lining in a former fistula tract.

  3. Hair cortisol measurement in mitotane-treated adrenocortical cancer patients.

    The only approved drug for the treatment of adrenocortical cancer (ACC) is mitotane. Mitotane is adrenolytic and therefore, hydrocortisone replacement therapy is necessary. Since mitotane increases cortisol binding globulin (CBG) and induces CYP3A4 activity, high doses of hydrocortisone are thought to be required. Evaluation of hydrocortisone therapy in mitotane-treated patients has been difficult since there is no good marker to evaluate hydrocortisone therapy. Measurement of cortisol in scalp hair is a novel method that offers the opportunity to measure long-term cortisol levels. Our aim was to evaluate whether hair cortisol measurements could be useful in evaluating recent hydrocortisone treatment in mitotane-treated ACC patients. Hair cortisol levels were measured in 15 mitotane-treated ACC patients on hydrocortisone substitution and 96 healthy individuals. Cortisol levels were measured in 3 cm hair segments, corresponding to a period of 3 months. Hair cortisol levels were higher in ACC patients compared to healthy individuals (pcortisol levels above the reference range. None of the patients had hair cortisol levels below normal. In contrast to hydrocortisone doses (β=0.03, p=0.93), hair cortisol levels were associated with BMI (β=0.53, p=0.042). There was no correlation between hair cortisol levels and hydrocortisone doses (β=0.41, p=0.13). Almost half of the ACC patients had high hair cortisol levels, suggesting long-term over-substitution of hydrocortisone in some of the patients, whereas none of the patients was under-substituted. Hair cortisol measurements might be useful in long-term monitoring hydrocortisone treatment in mitotane-treated ACC patients.

    2011-01-01

    With an incidence of over 3.5 million nonmelanoma skin cancers (NMSCs) per year in the United States, there is an increasing need for effective, cost-effective treatments for NMSC. When surgical excision is impractical or not feasible, methyl aminolevulinate photodynamic therapy (MAL-PDT) has demonstrated consistently high long-term cure rates ranging from 70-90%, with superior cosmetic outcomes compared with other treatment modalities. With the exception of invasive squamous cell carcinoma, MAL-PDT has been successful in treating all types of NMSC, especially in patients with multiple comorbidities, field cancerization, and lesions in cosmetically sensitive locations. Herein, a step-by-step description of the procedure for MAL-PDT is provided, followed by a review of outcomes from large clinical trials performed over the past 15 years for each variant of NMSC. After reading this review, clinicians should have a thorough understanding of the benefits and limits of MAL-PDT, and should be able to add this valuable procedure to their armamentarium of therapies for NMSC.

    In the present work, the degradation of olive mill wastewaters previously treated by an ozonation stage has been studied by an aerobic biological oxidation. The substrate evolution (based on chemical oxygen demand), biomass (measured as volatile suspended solids) and total polyphenolic contents were followed during each experiment. A kinetic study is performed by using the Contois model, which applied to the experimental data, provides the specific kinetic parameters of this model. The deduced kinetic equation for the consume of substrate is q=17.0 S/(18.2 X + So X) g COD/ gVSS day. Moreover, others interesting biological parameters like the cellular yied coefficient and the kinetic rate constant for the endogenous metabolism were determined, obtaining a values of 0.214 g VSS/g COD and 0.167 day''-1, respectively.

    In this study, wastewater from the output of three different secondary treatment facilities (Activated Sludge, Moving Bed Bioreactor and Coagulation-Flocculation) present in the municipal wastewater treatment plant of Vidy, Lausanne (Switzerland), was further treated with various oxidation processes (UV, UV/H2O2, solar irradiation, Fenton, solar photo-Fenton), at laboratory scale. For this assessment, 6 organic micropollutants in agreement with the new environmental legislation requirements in Switzerland were selected (Carbamazepine, Clarithromycin, Diclofenac, Metoprolol, Benzotriazole, Mecoprop) and monitored throughout the treatment. Also, the overall removal of the organic load was assessed. After each secondary treatment, the efficiency of the AOPs increased in the following order: Coagulation-Flocculation < Activated Sludge < Moving Bed Bioreactor, in almost all cases. From the different combinations tested, municipal wastewater subjected to biological treatment followed by UV/H2O2 resulted in the highest elimination levels. Wastewater previously treated by physicochemical treatment demonstrated considerably inhibited micropollutant degradation rates. The degradation kinetics were determined, yielding: k (UV) < k (UV/H2O2) and k (Fenton) < k (solar irradiation) < k (photo-Fenton). Finally, the evolution of global pollution parameters (COD & TOC elimination) was followed and the degradation pathways for the effluent organic matter are discussed.

    Kyphoplasty has been shown to provide symptomatic relief of vertebral compression fractures refractory to medical therapy. However, few reports have focused on refracture of cemented vertebrae after kyphoplasty. The presence of cemented vertebrae refracture concurrent with cement fragmentation is an extremely rare condition. We reported an 86-year-old man with a T12 osteoporotic compression fracture undergoing the kyphoplasty treatment. The patient postoperatively continued to have back pain at the same level. The solid lumped polymethylmethacrylate (PMMA) mass and inadequate use and insufficient filling of PMMA cement were observed in postoperative radiographs and magnetic resonance image (MRI) examination. He refused to receive the surgical intervention, but had not strict compliance with oral anti-osteoporotic medications. Ten months postoperatively, refracture of osteoporotic vertebral body concurrent with cement fragmentation occurred at the previously kyphoplasty-treated vertebral level. Bone mineral analysis showed severe osteoporosis with a T-score of -4.0. The patient finally obtained therapeutic benefit of pain relief and bony union of T12 vertebral body by consistently adhering to anti-osteoporotic medication treatment. This case illustrated that patients who underwent kyphoplasty to treat osteoporotic vertebral compression fractures with intravertebral fracture should be strictly followed up and supervised in their anti-osteoporotic medication treatment. The interdigitation injection pattern of PMMA and sufficient PMMA filling with trabeculae in the kyphoplasty procedure also might prevent refracture of the cemented vertebrae concurrent with PMMA fragmentation.

    Cytotoxic T lymphocyte-associated antigen 4 (CTLA-4) functions as a negative regulator of endogenous and vaccine-induced antitumor immunity. The administration of fully human anti-CTLA-4 blocking monoclonal antibodies to advanced-cancer patients increases immune-mediated tumor destruction in some subjects. Nonetheless, patients that respond also frequently manifest serious inflammatory pathologies, raising the possibility that the therapeutic and toxic effects of CTLA-4 blockade might be linked. Here we show that periodic infusions of anti-CTLA-4 antibodies after vaccination with irradiated, autologous tumor cells engineered to secrete GM-CSF (GVAX) generate clinically meaningful antitumor immunity without grade 3 or 4 toxicity in a majority of metastatic melanoma patients. The application of this sequential immunotherapy to advanced ovarian carcinoma patients also revealed that tumor destruction and severe inflammatory pathology could be dissociated, although further refinements are required to increase clinical responses and to minimize toxicity in this population. The extent of therapy-induced tumor necrosis was linearly related to the natural logarithm of the ratio of intratumoral CD8(+) effector T cells to FoxP3(+) regulatory T cells (Tregs) in posttreatment biopsies. Together, these findings help clarify the immunologic and clinical effects of CTLA-4 antibody blockade in previously vaccinated patients and raise the possibility that selective targeting of antitumor Tregs may constitute a complementary strategy for combination therapy.

    In contrast to malaria, multiple sclerosis (MS) is infrequently found in Black Africans. We describe a 29 year old Nigerian female who developed an MS-like condition with symptoms similar to relapsing-remitting MS following malaria infection, leading to a diagnosis of MS. However, absence of hyperintense lesions in the brain and spinal cord presented a conundrum since not all the diagnostic criteria for MS were met. Pathology supported genetic testing (PSGT) was applied to combine family and personal medical history, lifestyle factors, and biochemical test results for interpretation of genetic findings. This approach provides a means of identifying risk factors for different subtypes of demyelinating disease. The patient was subsequently treated according to an individualised intervention program including nutritional supplementation as well as a change in diet and lifestyle. Deficiencies of vitamin B12, iron and vitamin D were addressed. Genetic analysis revealed absence of the HLA DRB1*1501 allele, considered to be the most prominent genetic risk factor for MS. Extended mutation analysis identified variations in three genes in the folate-vitamin B12 metabolic pathway, which could have increased the patient's sensitivity to the antifolate drugs used to treat the malaria. A glutathione-S-transferase GSTM1 null allele, previously associated with neurological complications of malaria, was also detected. Furthermore, a heterozygous variation in the iron-related transmembrane protease serine 6 (TMPRSS6) gene, rs855791 was found, which could have impacted the patient's iron status following two successive blood donations and exposure to malaria preceding the MS diagnosis. PSGT identifies relevant risk factors for demyelinating disorders resembling MS and uses the data for individualised treatment programs, and to systematically build a database that can provide evidence in large patient cohorts. Follow-up investigations may be suggested, such as whole exome sequencing

    The aim of this retrospective study was to determine whether patients with previous peptide receptor radionuclide therapy using high-activity {sup 111}In-pentetreotide can be safely treated with {sup 177}Lu-octreotate and whether addition of radiosensitising chemotherapy increases the toxicity of this agent. Records of 27 patients (aged 17-75) who received 69 (median 3 per patient) {sup 177}Lu-octreotate administrations, including 29 in conjunction with radiosensitising infusional 5-fluorouracil (5-FU) (n = 27), or capecitabine (n = 2), between October 2005 and July 2007 subsequent to 1-8 prior cycles of {sup 111}In-pentetreotide therapy were analysed. Toxicity was assessed during and at 8-12 weeks post-treatment, with further long-term assessments including survival status reviewed till death or study close-out date of 1 November 2009. Reduction in blood counts was most marked following the first dose of {sup 177}Lu-octreotate but at early follow-up the only major haematological toxicity was a single case of grade 4 lymphopaenia. Both the presence of bone metastases and the administration of chemotherapy tended to result in greater reduction in blood counts, but these differences did not reach statistical significance. On long-term follow-up, 16 patients (59%) are alive with median overall survival of 36 months (32-44 months from first {sup 177}Lu-octreotate therapy). None of the recorded deaths was directly related to treatment toxicity. One patient had late grade 4 anaemia and thrombocytopaenia secondary to bone marrow failure from progressive infiltration by tumour. No other significant long-term haematological toxicities were recorded and no leukaemia was observed. No renal toxicity was observed on serial serum creatinine or radionuclide glomerular filtration rate (GFR) determination on initial or long-term follow-up. {sup 177}Lu-octreotate is a safe and well-tolerated therapy for patients who have previously been treated with {sup 111}In-pentetreotide and can

    2016-01-01

    Background: Patient-level data from 2 phase III studies in patients with previously untreated, advanced-stage, nonsquamous non–small cell lung cancer (NSCLC) were pooled to examine outcomes with bevacizumab and chemotherapy based on age. Methods: Data from patients randomized to paclitaxel–carboplatin (PC)+bevacizumab in the Eastern Cooperative Oncology Group 4599 (E4599) and PointBreak studies were pooled and compared with E4599 patients randomized to PC alone. Patients were grouped by age: below 65, 65 to 74, 70 to 74, below 75, and 75 years or above. A multivariable model was used to calculate hazard ratios (HRs) and corresponding 95% confidence intervals (CIs) using time-to-event outcomes. Adverse events (AEs) were assessed by age group in each study. Results: The PC+bevacizumab and PC arms comprised 901 and 444 patients, respectively. PC+bevacizumab was associated with significant increases in overall survival relative to PC in patients below 65 years (hazards ratio [HR], 0.75; 95% confidence interval [CI], 0.62-0.89), 65 to 74 years (HR, 0.80; 95% CI, 0.64-1.00), 70 to 74 years (HR, 0.68; 95% CI, 0.48-0.96), and below 75 years (HR, 0.78; 95% CI, 0.68-0.89) but not in those aged 75 years or above (HR, 1.05; 95% CI, 0.70-1.57). Increased incidence of grade ≥3 AEs was reported with PC+bevacizumab versus PC in patients below 75 years (63% vs. 48%; P<0.05) and 75 years or above (81% vs. 56%; P <0.05) in E4599. Conclusions: This analysis suggests that the survival benefits associated with PC+bevacizumab extend to patient subgroups below 75 years with advanced-stage NSCLC; no benefit, however, was observed for bevacizumab-eligible patients who were 75 years or above.

    Full Text Available Typhoid fever is commonly characterized by fever and abdominal pain. Rare complications include intestinal hemorrhage, bowel perforation, delirium, obtundation, and septic shock. Herein we describe the case of a previously healthy 16-year-old male without history of travel, diagnosed with typhoid fever complicated by septic shock and acute respiratory distress syndrome treated with high-dose dexamethasone. This case details severe complications of typhoid fever that are uncommonly seen in developed countries, and the successful response to high-dose dexamethasone as adjunct therapy. High-dose dexamethasone treatment has reportedly decreased Salmonella Typhi mortality, but controlled studies specifically performed in children are lacking, and most reports of its use are over 30 years old and all have originated in developing countries. Providers should include Salmonella Typhi in the differential diagnosis of the pediatric patient with fever, severe abdominal pain, and enteritis, and be aware of its potentially severe complications and the limited data on safety and efficacy of adjunctive therapies that can be considered in addition to antibiotics.

    Objective: To explore the efficacy of Tongkuaixiao Babu plaster (痛块消巴剂, TKXBBP)in treating cancer pain. Methods: In the clinical observation, sixty-five patients with moderate or severe cancer pain were randomly divided into two groups: 32 in the treated group (TKXBBP group) and 33 in the control group (Bucinnazine group). The therapeutic effects in relieving pain, improving quality of life (QOL),and the rate of satisfaction the patients felt of the two groups were compared respectively. Results: TKXBBP was effective in treating cancer pain. There wasn't any statistically significant difference in total effective rate (P>0.05), but the statistical difference was significant in obvious remission rate (P<0.05) between the treated and control group, and the effect on serious pain shown in the treated group was better than that of the control group (P<0.05). The difference in the initiation time of relieving cancer pain was insignificant (P>0.05), while in the remission period, the treated group showed its treatment was obviously superior to that of the control group (P<0.05). TKXBBP showed better effect in the improvement of QOL (P<0.05)and satisfaction rate, with significant difference between the treated and the control groups (P<0.01). Conclusion: TKXBBP's effect in treating cancer pain was obvious, its application was safe and convenient. It was shown that the external treatment with this kind of Chinese medicine had great advantage in treating cancer pain.

    Three freezing-point regulators (glycine, sodium chloride and D-sorbitol) were employed to optimize thermophysical properties of Pacific white shrimp (Litopenaeus vannamei) using response surface methodology (RSM). The independent variables were glycine content (0.250-1.250 %), sodium chloride content (0.500-2.500 %) and D-sorbitol content (0.125-0.625 %) and analysis of variance showed that the effects of glycine, sodium chloride and D-sorbitol on the thermophysical properties were statistically significant (P < 0.05). The coefficient of determination, R (2) values for initial freezing point (T i ), unfreezable water mass fraction (W u ), apparent specific heat (C app ) and Enthalpy (H) were 0.896 ~ 0.999. The combined effects of these independent variables on T i , W u , C app and H were investigated. The results indicated that T i , C app and H varied curvilinearly with increasing of glycine, sodium chloride and D-sorbitol content whereas W u increased nearly linearly. Based on response plots and desirability functions, the optimum combination of process variables for Pacific white shrimp previously treated with freezing-point regulators were 0.876 % for glycine content, 2.298 % for sodium chloride content and 0.589 % for D-sorbitol content, correspondently the optimized thermophysical properties were T i , - 5.086 °C; W u , 17.222 %; C app , 41.038 J/g °C and H, 155.942 J/g, respectively. Briefly, the application of freezing-point regulators depressed T i and obtained the optimum W u , C app and H, which would be obviously beneficial for the exploitation of various thermal processing and food storage.

    AZD5363, an inhibitor of protein kinase B (AKT), is currently in clinical trials assessing the potential of the phosphoinositide 3-kinase (PI3K)/AKT/mammalian target of rapamycin (mTOR) pathway. The purpose of the present study was to identify conditions that increase the sensitivity of cancer cells to AZD5363. Microscopic examination revealed that treatment of cancer cells with a low concentration of salinomycin reduced cellular growth of AZD5363-treated breast cancer cells. Furthermore, fluorescence-activated cell sorting (FACS) analysis, Hoechst staining, and annexin V staining revealed that co-treatment with salinomycin sensitizes AZD5363-treated cancer cells via increased apoptosis with S-phase arrest. These results suggest that salinomycin can be applied to increase treatment efficacy for AZD5363-treated cancer cells. Our findings may contribute to improving the efficacy of the development of AZD5363-based sensitization therapies for patients with cancer.

    Cancer metastasis accounts for the high mortality of many types of cancer. Owing to the unique advantages of high specificity and minimal invasiveness, photothermal therapy (PTT) has been evidenced with great potential in treating cancer metastasis. In this review, we outline the current approaches of PTT with respect to its application in treating metastatic cancer. PTT can be used alone, guided with multimodal imaging, or combined with the current available therapies for effective treatment of cancer metastasis. Numerous types of photothermal nanotherapeutics (PTN) have been developed with encouraging therapeutic efficacy on metastatic cancer in many preclinical animal experiments. We summarize the design and performance of various PTN in PTT alone and their combinational therapy. We also point out the lacking area and the most promising approaches in this challenging field. In conclusion, PTT or their combinational therapy can provide an essential promising therapeutic modality against cancer metastasis.

    2015-11-10

    The American Society of Clinical Oncology (ASCO) convened a subcommittee to develop recommendations on improving the evidence base for treating older adults with cancer in response to a critical need identified by the Institute of Medicine. Older adults experience the majority of cancer diagnoses and deaths and make up the majority of cancer survivors. Older adults are also the fastest growing segment of the US population. However, the evidence base for treating this population is sparse, because older adults are underrepresented in clinical trials, and trials designed specifically for older adults are rare. The result is that clinicians have less evidence on how to treat older adults, who represent the majority of patients with cancer. Clinicians and patients are forced to extrapolate from trials conducted in younger, healthier populations when developing treatment plans. This has created a dearth of knowledge regarding the risk of toxicity in the average older patient and about key end points of importance to older adults. ASCO makes five recommendations to improve evidence generation in this population: (1) Use clinical trials to improve the evidence base for treating older adults with cancer, (2) leverage research designs and infrastructure for generating evidence on older adults with cancer, (3) increase US Food and Drug Administration authority to incentivize and require research involving older adults with cancer, (4) increase clinicians' recruitment of older adults with cancer to clinical trials, and (5) use journal policies to improve researchers' reporting on the age distribution and health risk profiles of research participants.

  19. Prediction of Candidate Drugs for Treating Pancreatic Cancer by Using a Combined Approach.

    Directory of Open Access Journals (Sweden)

    Yanfen Ma

    Full Text Available Pancreatic cancer is the leading cause of death from solid malignancies worldwide. Currently, gemcitabine is the only drug approved for treating pancreatic cancer. Developing new therapeutic drugs for this disease is, therefore, an urgent need. The C-Map project has provided a wealth of gene expression data that can be mined for repositioning drugs, a promising approach to new drug discovery. Typically, a drug is considered potentially useful for treating a disease if the drug-induced differential gene expression profile is negatively correlated with the differentially expressed genes in the target disease. However, many of the potentially useful drugs (PUDs identified by gene expression profile correlation are likely false positives because, in C-Map, the cultured cell lines to which the drug is applied are not derived from diseased tissues. To solve this problem, we developed a combined approach for predicting candidate drugs for treating pancreatic cancer. We first identified PUDs for pancreatic cancer by using C-Map-based gene expression correlation analyses. We then applied an algorithm (Met-express to predict key pancreatic cancer (KPC enzymes involved in pancreatic cancer metabolism. Finally, we selected candidates from the PUDs by requiring that their targets be KPC enzymes or the substrates/products of KPC enzymes. Using this combined approach, we predicted seven candidate drugs for treating pancreatic cancer, three of which are supported by literature evidence, and three were experimentally validated to be inhibitory to pancreatic cancer celllines.

    2012-07-01

    Prostate cancer is the most common cancer among North American and European men, but its treatment continues to be problematic owing to serious side-effects, including erectile dysfunction, urinary incontinence, and potential lower GI complications. Robotic radiosurgery offers a novel, rapid, non-invasive outpatient treatment option for prostate cancer that combines robotics, advanced image-guided motion detection, and automated real-time corrective spatial positioning with submillimeter precision. This book examines all aspects of the treatment of prostate cancer with robotic radiosurgery. After introductory sections on radiosurgery as a multidisciplinary practice and specific issues relating to prostate cancer, the important challenge posed by prostate motion when administering radiation therapy is examined in depth, with detailed discussion as to how image-guided robotic radiosurgery overcomes this problem by continously identifying the precise location of the prostate throughout the course of treatment. A further major section is devoted to a discussion of techniques and potential radiobiological and clinical advantages of hypofractionated radiation delivery by means of robotic radiosurgery systems. The book closes by discussing other emerging genitourinary applications of robotic radiosurgery. All of the authors are experts in their field who present a persuasive case for this fascinating technique. (orig.)

    Full Text Available To investigate the recent trends in definitive management of esophageal cancer, the records of 138 consecutive patients treated with radical intent in a single institution between 1995 and 2003 were reviewed and analyzed. The median follow-up period was 5.7 years (range 1.1 to 10.4 years. Seventy-seven patients were treated with radiation therapy (RT only and 61 with combined regimens (CRT, in which RT was combined with either radical surgery or chemotherapy, or both. The overall survival of the entire cohort was 32% over two years and 20% over five years. The survivorship in the RT group was 17% over two years and 5% over five years. In the CRT group, 51% and 35% survived over two and five years, respectively. From all the potential prognostic factors examined by univariate and multivariate analyses, only male sex and use of CRT were strongly associated with better survivorship. There was no significant difference in the outcomes among the different regimens of CRT. Survivorship was not affected by the location or histology of the tumour, clinical stage, dose of RT or use of endoluminal brachytherapy in addition to external beam RT. There was a greater tendency to use RT only more often in older patients, but patient age did not affect survivorship. The proportion of patients treated with CRT did not change significantly over the last versus the first four years of the observed period. Combined regimens are undoubtedly superior to RT as a single modality. The long-term survivorship of patients in a subgroup of our patients treated with combined modality protocols compared favourably with the previously reported results in the literature and specifically in prospective randomized trials. However, the optimal combined modality regimen is yet to be defined.

    Brian Spencer Hoyt

    2014-01-01

    Full Text Available Radiation therapy is associated with a variety of complications, including the development of primary skin cancers in the radiated region. However, it is rare for patients with visceral cancers who are treated with radiation therapy to subsequently develop cutaneous metastasis within the radiation port. We describe two patients with internal malignancies who developed cutaneous metastases within their radiation ports following radiotherapy. In addition, we used PubMed to perform an extensive literature review and identify additional reports of cutaneous metastasis within a radiation port. We excluded patients who developed melanoma or primary skin cancers in the radiation port. We also excluded patients with non-solid organ malignancies. Herein, we summarize the characteristics of 23 additional patients who experienced radiation port cutaneous metastases and explore possible mechanisms for the occurrence of radiation port cutaneous metastases.

    Dickkopf-1 (DKK1) is a secreted Wnt/β-catenin pathway antagonist involved in embryogenesis. It was first described 25 years ago for its function in head induction and limb morphogenesis. Since then, this protein has been widely studied in the context of active Wnt/β-catenin signalling during cellular differentiation and development. Dysregulation of DKK1 has been associated with bone pathologies and has now emerged as a potential biomarker of cancer progression and prognosis for several types of malignancies. Reducing the amount of circulating DKK1 may reveal a simple and efficient strategy to limit or reverse cancer growth. This review will provide an overview of the role of Dickkopf-1 in cancer and explore its potential use as a biomarker and therapeutic target.

    Purpose: To investigate the IFOX regimen (gefitinib, 5-fluorouracil [5-FU], leucovorin and oxaliplatin) as first-line therapy in patients with metastatic colorectal cancer. Experimental Design: Eligible patients had stage IV colorectal adenocarcinoma, and had not received prior chemotherapy for metastatic disease. Each cycle consisted of 14 days. Cycle 1 consisted of FOLFOX-4 (oxaliplatin, leucovorin, and 5-FU). All subsequent cycles consisted of FOLFOX-4 with gefitinib at 500 mg PO daily throughout the 14 days cycle. Results: Forty-five patients were enrolled and are assessable for toxicity. Forty-three patients are assessable for response. Thirty-one of the 43 patients (72%), had either a complete or partial response by RECIST criteria. Median overall survival was 20.5 months. Median time to progression was 9.3 months. Commonly encountered grade 3/4 toxicities included diarrhea in 67% of patients and neutropenia in 60%. Grade 2 acneiform skin rash typical of gefitinib occurred in 60% of patients. Conclusions: IFOX is an active first-line regimen in patients with metastatic colorectal adenocarcinoma, demonstrating higher response rates but also increased toxicities compared with FOLFOX-4 alone in a similar patient population.

    Full Text Available Abstract Introduction Lung and gastric cancers are the first and second leading causes of death from cancer worldwide, and are especially prevalent in Eastern Asia. Relatively few reports are available in relation to the treatment and outcome of synchronous lung and gastric cancers, although there are increasing numbers of patients with these cancers. Efforts to develop more effective drugs for the treatment of synchronous cancers, without serious adverse effects, have been intensifying. Pemetrexed, a multi-targeted antifolate enzyme inhibitor, was approved by the United States Food and Drug Administration as a first-line chemotherapy for advanced non-squamous non-small cell lung cancer in 2007. Although clinical activity against several tumor types of adenocarcinoma, including gastric cancer, has been demonstrated, the efficacy of pemetrexed for gastric cancer remains to be fully evaluated. Case presentation We report a case involving a 62-year-old Japanese woman with synchronous locally-advanced poorly-differentiated lung adenocarcinoma and poorly-differentiated gastric adenocarcinoma, containing signet-ring cells distinguished by immunohistochemical profiles. She had been treated with carboplatin and pemetrexed as a first-line chemotherapy for lung cancer, and had achieved partial responses for both lung and gastric cancers. These responses led to a favorable 12-month progression-free survival after the initiation of chemotherapy, and the patient is still alive more than 33 months after diagnosis. Conclusions This case suggests a new chemotherapeutic regimen for patients with synchronous multiple primary cancers that have an adenocarcinoma background.

    Chimeric antigen receptor (CAR) T cells have proven that engineered immune cells can serve as a powerful new class of cancer therapeutics. Clinical experience has helped to define the major challenges that must be met to make engineered T cells a reliable, safe, and effective platform that can be deployed against a broad range of tumors. The emergence of synthetic biology approaches for cellular engineering is providing us with a broadly expanded set of tools for programming immune cells. We discuss how these tools could be used to design the next generation of smart T cell precision therapeutics.

    Full Text Available Chemotherapy Induced Nausea and Vomiting (CINV is among the most intensive side effects and critical concerns for patients with cancer. Most of these patients experience nausea and vomiting after chemotherapy. Sometimes, this is so annoying that it may prevent them from continuing the therapy. With the recent advances, a variety of therapeutic methods are innovated and applied to control CINV. Among them, the main methods include medicinal therapy, relaxation, and herbal therapy. Yet, using dexamethasone together with massage therapy and ginger is identified as the most effective method.

Snyder, Department of Neuroscience, Johns Hopkins University, Baltimore, MD, USAAbstract: Recently, I put forth the hypothesis that the signaling molecule, norepinephrine (NE, is an etiological factor in a number of types of cancer. In this brief commentary, I summarize evidence that NE plays a role in cancer and describe details involved in testing the hypothesis in humans through epidemiological investigation of existing medical records of persons who have taken pharmaceutical drugs that affect NE. If NE plays an etiological role in cancers of a number of organs, then taking a single pharmaceutical drug (such as clonidine, prazosin, or propranolol that weakens NE signaling systemically, may simultaneously prevent or treat many different types of cancer, and this may represent a breakthrough in pharmaceutical prevention and possibly treatment of cancer.Keywords: norepinephrine, acetylcholine, cancer, clonidine, prazosin, propranolol

    Neurosurgical craniotomy, craniectomy, or other trans-galeal interventions are performed for a variety of indications, including the resection of benign or malignant tumors, hematoma evacuation, and for the management of intractable seizure disorders. Despite an overall low complication rate of intervention, wound healing complications such as dehiscence, surgical site infection, and cerebrospinal fluid leak are not uncommon. A retrospective review was performed of all patients who underwent scalp incision closure at a single institution by a single plastic surgeon between 2006 and 2013. Sixty patients (83 procedures) were included in the study. Fifty-seven patients (95.0 %) underwent previous craniotomy, craniectomy, or other trans-galeal procedure. Of the total 60 patients, 35 patients received preoperative radiation. Sixteen patients received bevacizumab prior to their index case, while 12 received bevacizumab postoperatively. Ten patients (16.7 %) required additional plastic surgical intervention for wound complications after their index plastic surgery procedure. Plastic surgery was consulted prophylactically in 34 patients (38 procedures). When plastic surgery was consulted prophylactically, 4 patients (11.8 %) required further wound revision. None of the 14 patients who underwent prophylactic plastic surgery closure for previous scalp incision, preoperative bevacizumab, and XRT administration required re-intervention. Plastic surgery closure of complex scalp incisions reduces the incidence of wound complications among patients who underwent previous neurosurgical intervention, XRT administration, and preoperative bevacizumab administration. This is particularly true when plastic surgery closure is performed "prophylactically." Further collaboration between the neurosurgical and plastic surgery teams is therefore warranted, particularly in the setting of these high-risk cases.

    Here, we propose a new strategy for the treatment of early cancerous lesions and advanced metastatic disease, via the selective targeting of cancer stem cells (CSCs), a.k.a., tumor-initiating cells (TICs). We searched for a global phenotypic characteristic that was highly conserved among cancer stem cells, across multiple tumor types, to provide a mutation-independent approach to cancer therapy. This would allow us to target cancer stem cells, effectively treating cancer as a single disease of "stemness", independently of the tumor tissue type. Using this approach, we identified a conserved phenotypic weak point - a strict dependence on mitochondrial biogenesis for the clonal expansion and survival of cancer stem cells. Interestingly, several classes of FDA-approved antibiotics inhibit mitochondrial biogenesis as a known "side-effect", which could be harnessed instead as a "therapeutic effect". Based on this analysis, we now show that 4-to-5 different classes of FDA-approved drugs can be used to eradicate cancer stem cells, in 12 different cancer cell lines, across 8 different tumor types (breast, DCIS, ovarian, prostate, lung, pancreatic, melanoma, and glioblastoma (brain)). These five classes of mitochondrially-targeted antibiotics include: the erythromycins, the tetracyclines, the glycylcyclines, an anti-parasitic drug, and chloramphenicol. Functional data are presented for one antibiotic in each drug class: azithromycin, doxycycline, tigecycline, pyrvinium pamoate, as well as chloramphenicol, as proof-of-concept. Importantly, many of these drugs are non-toxic for normal cells, likely reducing the side effects of anti-cancer therapy. Thus, we now propose to treat cancer like an infectious disease, by repurposing FDA-approved antibiotics for anti-cancer therapy, across multiple tumor types. These drug classes should also be considered for prevention studies, specifically focused on the prevention of tumor recurrence and distant metastasis. Finally, recent

    Irinotecan and cisplatin demonstrated promising outcomes in extensive-stage small-cell lung cancer. According to the dosage and schedule of irinotecan, efficacy and toxicity profiles showed subtle differences. This study was designed to evaluate efficacy and toxicity of 3-week schedule of irinotecan/cisplatin in patients with previously untreated extensive-stage small-cell lung cancer. The primary objective was to evaluate response rate and secondary objectives were overall survival and progression-free survival. Patients with previously untreated extensive-stage small-cell lung cancer were enrolled. Irinotecan 65 mg m−2 was administered on days 1 and 8 and cisplatin 60 mg m−2 on day 1. Treatment was repeated every 3 weeks. Seven out of 54 patients (13.0%) had complete response, and partial response was observed in 33 (61.1%). The overall response rate was 74.1% (95% CI; 62.0–82.2%). Stable disease was observed in eight (14.8%) and no progressive disease was observed. After a median follow-up duration of 28.7 months, the median overall survival and progressive-free survival were 13.6 and 6.5 months, respectively. Major grade 3/4 toxicities were neutropenia (50.0%), anorexia (42.6%), diarrhoea (29.6%), fatigue (29.6%) and vomiting (13.0%). There was one treatment-related death owing to pneumonia. Three-week schedule of irinotecan/cisplatin showed effective antitumour activity and moderate toxicities in patients with previously untreated extensive-stage small-cell lung cancer. PMID:17133266

    Breast cancer is the most common cancer among women worldwide and novel therapeutic agents are needed to treat this disease. The plant-based alkaloid berberine has potential therapeutic applications for breast cancer, although a better understanding of the genes and cellular pathways regulated by this compound is needed to define the mechanism of its action in cancer treatment. In this review, the molecular targets of berberine in various cancers, particularly breast cancer, are discussed. Berberine was shown to be effective in inhibiting cell proliferation and promoting apoptosis in various cancerous cells. Some signaling pathways affected by berberine, including the MAP (mitogen-activated protein) kinase and Wnt/β-catenin pathways, are critical for reducing cellular migration and sensitivity to various growth factors. This review will discuss recent studies and consider the application of new prospective approaches based on microRNAs and other crucial regulators for use in future studies to define the action of berberine in cancer. The effects of berberine on cancer cell survival and proliferation are also outlined.

    Anti-programmed cell death-1 and anti-programmed cell death ligand-1 (PD-L1) monotherapies have shown promising clinical activity in advanced, refractory non-small-cell lung cancer (NSCLC), but antitumor activity appears to be greater in patients with PD-L1(+) tumors compared with patients harboring PD-L1(-) tumors. Combining the anti-PD-L1 antibody durvalumab and the anti-cytotoxic T-lymphocyte antigen 4 antibody tremelimumab offers the potential for antitumor activity in patients with advanced NSCLC, regardless of PD-L1 tumor status. ARCTIC (NCT02352948) is a global, phase III, randomized, open-label multicenter study in patients with advanced NSCLC assessing the safety and clinical activity of durvalumab versus standard of care (SoC; erlotinib, gemcitabine, or vinorelbine) in patients with PD-L1(+) tumors (≥25% of tumor cells with membrane staining using VENTANA PD-L1 [SP263] CDx Assay) (Sub-study A) and the combination of durvalumab + tremelimumab or either agent as monotherapy versus SoC in patients with PD-L1(-) tumors (Sub-study B). Eligible patients are those with locally advanced or metastatic NSCLC (Stage IIIB/IV), without epidermal growth factor receptor tyrosine kinase activating mutations or anaplastic lymphoma kinase rearrangements, who have received at least 2 prior systemic regimens, including 1 platinum-based chemotherapy regimen. Co-primary endpoints are progression-free survival and overall survival. Secondary endpoints include the proportion of patients alive at 12 months, objective response rate, duration of response, progression-free survival at 6 and 12 months, safety and tolerability, pharmacokinetics, immunogenicity, and quality of life. The exploratory endpoints will assess potential biomarkers of treatment response. Recruitment started in January 2015 and is ongoing.

    Pancreatic cancer remains one of the deadliest of all cancers despite aggressive surgical treatment combined with adjuvant radiotherapy and chemotherapy. Chemoresistance and radioresistance are the principal causes of failure of pancreatic cancer patients to respond to therapy. Conditionally replication competent adenovirus (CRCA)-based cancer gene therapy is an innovative strategy for treating cancers displaying inherent resistance to treatment. Limitations of current adenovirus (Ad)-based gene therapies for malignant tumors include lack of cancer-specificity, and effective and targeted delivery. To remedy this situation, CRCAs have been designed that express E1A, necessary for Ad replication, under the control of a cancer-specific progression elevated gene-3 promoter (PEG-Prom) with concomitant expression of an immunomodulatory cytokine, such as mda-7/IL-24 or interferon-γ (IFN-γ), under the control of a ubiquitous and strong cytomegalovirus promoter (CMV-Prom) from the E3 region. These bipartite CRCAs, when armed with a transgene, are called cancer terminator viruses (CTVs), i.e., Ad.PEG-E1A-CMV-mda-7 (CTV-M7) and Ad.PEG-E1A-CMV-IFN-γ (CTV-γ), because of their universal effectiveness in cancer treatment irrespective of p53/pRb/p16 or other genetic alterations in tumor cells. In addition to their selective oncolytic effects in tumor cells, the potent 'bystander antitumor' properties of MDA-7/IL-24 and IFN-γ embody the CTVs with expanded treatment properties for both primary and distant cancers. Pancreatic cancer cells display a "translational block" of mda-7/IL-24 mRNA, limiting production of MDA-7/IL-24 protein and cancer-specific apoptosis. Specific chemopreventive agents abrogate this "translational block" resulting in pancreatic cancer-specific killing. This novel chemoprevention gene therapy (CGT) strategy holds promise for both prevention and treatment of pancreatic cancers where all other strategies have proven ineffective.

    Malignant primary and metastatic brain tumours continue to be associated with poor prognosis. Nevertheless, recent advances in molecular medicine, specifically in the strategies of gene therapy, targeting tumour cells, anti-angiogenesis and immunotherapy, have created novel tools that may be of therapeutic value. To date, gene therapy trials have not yet demonstrated clinical efficacy because of inherent defects in vector design. Despite this, advances in adenoviral technology, namely the helper-dependent adenoviral constructs (gutless) and the uncovering of brain parenchymal cells as effective and necessary targets for antitumour benefits of adenoviral-mediated gene transfer, suggest that developments in vector design may be approaching the point of clinical utility. Targeting tumour cells refers to strategies that destroy malignant but spare normal cells. A new assortment of oncolytic viruses have emerged, capable of specific lysis of cancer tissue while sparing normal cells and propagating until they reach the tumour borders. Furthermore, peptides have been transformed into bullets that specifically seek and destroy cancer cells. The concept of tumour angiogenesis has been challenged by new but still very controversial findings that tumour cells themselves may form blood channels. These results may lead to the redirecting of the molecular targets toward anti-angiogenesis in some tumours including glioblastoma multiform. Unfortunately, our knowledge regarding the immunological ignorance of the tumour is still limited. Even so, newly discovered molecules have shed light on novel pathways leading to the escape of the tumour from the immune system. Finally, significant limitations in our current experimental tumour models may soon be overcome by firstly, the development of models of reproducible organ-specific tumours in non-inbred animals and secondly applying genomics to individualize therapy for a particular tumour in a specific patient.

    2013-06-01

    Full Text Available The CDC25A-CDK2 pathway has been proposed as critical for the oncogenic action of human epidermal growth factor receptor 2 (HER2 in mammary epithelial cells. In particular, transgenic expression of CDC25A cooperates with HER2 in promoting mammary tumors, whereas CDC25A hemizygous loss attenuates the HER2-induced tumorigenesis penetrance. On the basis of this evidence of a synergism between HER2 and the cell cycle regulator CDC25A in a mouse model of mammary tumorigenesis, we investigated the role of CDC25A in human HER2-positive breast cancer and its possible implications in therapeutic response. HER2 status and CDC25A expression were assessed in 313 breast cancer patients and we found statistically significant correlation between HER2 and CDC25A (P = .007. Moreover, an HER2-positive breast cancer subgroup with high levels of CDC25A and very aggressive phenotype was identified (P = .005. Importantly, our in vitro studies on breast cancer cell lines showed that the HER2 inhibitor efficacy on cell growth and viability relied also on CDC25A expression and that such inhibition induces CDC25A down-regulation through phosphatidylinositol 3-kinase/protein kinase B pathway and DNA damage response activation. In line with this observation, we found a statistical significant association between CDC25A overexpression and trastuzumab-combined therapy response rate in two different HER2-positive cohorts of trastuzumab-treated patients in either metastatic or neoadjuvant setting (P = .018 for the metastatic cohort and P = .021 for the neoadjuvant cohort. Our findings highlight a link between HER2 and CDC25A that positively modulates HER2- targeted therapy response, suggesting that, in HER2-positive breast cancer patients, CDC25A overexpression affects trastuzumab sensitivity.

    Biliary tract cancer is a rare malignant tumor.There is limited knowledge about biology and natural history of this disease and considerable uncertainty remains regarding its optimal diagnostic and therapeutic management.The role of adjuvant therapy is object of debate and controversy.Although resection is identified as the most effective and the only potentially curative treatment,there is no consensus on the impact of adjuvant chemotherapy and/or radiotherapy on the high incidence of disease recurrence and on survival.This is mainly due to the rarity of this disease and the consequent difficulty in performing randomized trials.The only two prospectively controlled trials concluded that adjuvant chemotherapy did not improve survival.Most of the retrospective trials,which had limited sample size and included heterogeneous patients population and non-standardized therapies,suggested a marginal benefit of chemoradiotherapy in reducing locoregional recurrence and an uncertain impact on survival.Welldesigned multi-institutional randomized trials are necessary to clarify the role of adjuvant therapy.Two ongoing phase Ⅲ trials may provide relevant information.

    Full Text Available The potential clinical utility of genetic markers associated with response to fluoropyrimidine treatment in colorectal cancer patients remains controversial despite extensive study. Our aim was to test the clinical validity of both novel and previously identified markers of adverse events in a broad clinical setting. We have conducted an observational pharmacogenetic study of early adverse events in a cohort study of 254 colorectal cancer patients treated with 5-fluorouracil or capecitabine. Sixteen variants of nine key folate (pharmacodynamic and drug metabolising (pharmacokinetic enzymes have been analysed as individual markers and/or signatures of markers. We found a significant association between TYMP S471L (rs11479 and early dose modifications and/or severe adverse events (adjusted OR = 2.02 [1.03; 4.00], p = 0.042, adjusted OR = 2.70 [1.23; 5.92], p = 0.01 respectively. There was also a significant association between these phenotypes and a signature of DPYD mutations (Adjusted OR = 3.96 [1.17; 13.33], p = 0.03, adjusted OR = 6.76 [1.99; 22.96], p = 0.002 respectively. We did not identify any significant associations between the individual candidate pharmacodynamic markers and toxicity. If a predictive test for early adverse events analysed the TYMP and DPYD variants as a signature, the sensitivity would be 45.5 %, with a positive predictive value of just 33.9 % and thus poor clinical validity. Most studies to date have been under-powered to consider multiple pharmacokinetic and pharmacodynamic variants simultaneously but this and similar individualised data sets could be pooled in meta-analyses to resolve uncertainties about the potential clinical utility of these markers.

    Using a population-based cancer registry, Thuret et al. developed 3 nomograms for estimating cancer-specific mortality in men with penile squamous cell carcinoma. In the initial cohort, only 23.0% of the patients were treated with inguinal lymphadenectomy and had pN stage. To generalize the prediction models in clinical practice, we evaluated the performance of the 3 nomograms in a series of penile cancer patients who were treated with definitive surgery. Clinicopathologic information was obtained from 160 M0 penile cancer patients who underwent primary tumor excision and regional lymphadenectomy between 1990 and 2008. The predicted probabilities of cancer-specific mortality were calculated from 3 nomograms that were based on different disease stage definitions and tumor grade. Discrimination, calibration, and clinical usefulness were assessed to compare model performance. The discrimination ability was similar in nomograms using the TNM classification or American Joint Committee on Cancer staging (Harrell’s concordance index = 0.817 and 0.832, respectively), whereas it was inferior for the Surveillance, Epidemiology and End Results staging (Harrel ’s concordance index = 0.728). Better agreement with the observed cancer-specific mortality was shown for the model consisting of TNM classification and tumor grade, which also achieved favorable clinical net benefit, with a threshold probability in the range of 0 to 42%. The nomogram consisting of TNM classification and tumor grading was shown to have better performance for predicting cancer-specific mortality in penile cancer patients who underwent definitive surgery. Our data support the integration of this model in decision-making and trial design.

    We report a case of advanced gastric cancer, with cervical, axillary, and abdominal paraaortic lymph node metastases, that was successfully treated with chemotherapy and surgery. The disease was initially considered unresectable, and the patient was treated with orally administered S-1. Chemotherapy was effective, and all lymph node metastases disappeared after 6 courses. After 27 mo of chemotherapy, the patient underwent curative surgery, with subtotal gastrectomy and lymph node dissection. Histopathologic...

    Serum copper and ceruloplasmin levels (SCL, SCeL) in 57 patients with advanced cancer of the stomach (35 cases) or large intestine (22 cases) treated with polychemotherapy were studies. In gastroenteric cancer, SCL, which are already high in untreated patients, have a tendency to increase further in cases of progression of the disease, while they seem to significantly decrease in cases of remission. SCeL during the trial appeared to be correlated to the clinical evolution of the disease only in the case of stomach cancer. In large intestine cancer, SCeL did not show any significant variation in relation to the normal range. These observations, in particular on the behavior of SCL in the neoplasms of the digestive tract, are in accordance with the results of other studies. The authors are inclined to attach a diagnostic and prognostic value to the variation in SCL and SCeL in gastrointestinal cancer.

    Full Text Available Abstract Background Chinese medicine often targets more than one system and as such comprises several compounds, often in non-purified form, with treatments therefore consisting of whole extracts of herbs rather than isolated compounds. The additive and synergistic effects of the phytochemicals in OMN54, a novel mixture of extracts from three commonly used Chinese medicine components; Ganoderma lucidum, Salvia miltiorrhiza and Scutellaria barbata, were previously demonstrated to have potent anti-cancer activity. This study aims to test whether this heterogeneous, multifunctional and multitargeted agent has an acceptable toxicity profile. Methods We conducted preliminary and formal preclinical tolerability determination of OMN54 in Sprague-Dawley rats. In the preliminary study rats were given OMN54 by oral feeding daily for 14 days at doses of 1000 mg/kg, 1750 mg/kg, 2500 mg/kg or 3000 mg/kg per day. A subsequent daily dosing (x 28, 60, 120 or 180 formal toxicology study was conducted in male and female Sprague-Dawley rats at a dose of single dose of 2000 mg/kg/day. Results Significant body weight loss was noted in one of the rats treated at 3000 mg/kg/day, with decline beginning study day 11. This animal experienced mild GI toxicity in the form of diarrhoea. Gross observation indicated kidney damage (pale kidneys in both this group and in one rat treated at 2500 mg/kg/day. For the later studies, no body weight loss was noted over the course of the study. Blood counts and chemistry were not substantially altered following administration of OMN54, nor were there any findings on histological assessment of organs. Conclusion OMN54 was found to be well tolerated in rat models. OMN54 did not cause any microscopic, anatomic or pathologic changes in exposed animals at the concentrations and under the conditions employed in this study.

    Cancer remains to be one of the leading causes of death in the United States and around the world. The advent of modern drug-targeted therapies has undeniably improved cancer patients' cares. However, advanced metastasized cancer remains untreatable. Hence, continued searching for a safer and more effective chemoprevention and treatment is clearly needed for the improvement of the efficiency and to lower the treatment cost for cancer care. Cancer chemoprevention with natural phytochemical compounds is an emerging strategy to prevent, impede, delay, or cure cancer. This review summarizes the latest research in cancer chemoprevention and treatment using the bioactive components from natural plants. Relevant molecular mechanisms involved in the pharmacological effects of these phytochemicals are discussed. Pharmaceutical developmental challenges and opportunities in bringing the phytochemicals into the market are also explored. The authors wish to expand this research area not only for their scientific soundness, but also for their potential druggability.

  20. Treating cancer as an infectious disease--viral antigens as novel targets for treatment and potential prevention of tumors of viral etiology.

    Xing Guo Wang

    Full Text Available BACKGROUND: Nearly 20% of human cancers worldwide have an infectious etiology with the most prominent examples being hepatitis B and C virus-associated hepatocellular carcinoma and human papilloma virus-associated cervical cancer. There is an urgent need to find new approaches to treatment and prevention of virus-associated cancers. METHODOLOGY/PRINCIPAL FINDINGS: Viral antigens have not been previously considered as targets for treatment or prevention of virus-associated cancers. We hypothesized that it was possible to treat experimental HPV16-associated cervical cancer (CC and Hepatitis B-associated hepatocellular carcinoma (HCC by targeting viral antigens expressed on cancer cells with radiolabeled antibodies to viral antigens. Treatment of experimental CC and HCC tumors with (188Re-labeled mAbs to E6 and HBx viral proteins, respectively, resulted in significant and dose-dependent retardation of tumor growth in comparison with untreated mice or mice treated with unlabeled antibodies. CONCLUSIONS/SIGNIFICANCE: This strategy is fundamentally different from the prior uses of radioimmunotherapy in oncology, which targeted tumor-associated human antigens and promises increased specificity and minimal toxicity of treatment. It also raises an exciting possibility to prevent virus-associated cancers in chronically infected patients by eliminating cells infected with oncogenic viruses before they transform into cancer.

    Cognitive deficits are found in a number of breast-cancer patients who have undergone adjuvant (Cyclophosphamide, Methotrexate, and 5-Fluorouracil (CMF)) chemotherapy, but the underlying mechanisms are still unclear. The objective of this study is to investigate information processing in these patients with concurrent registration of brain activity. Twenty-six breast-cancer patients treated with adjuvant CMF chemotherapy and a control group of 23 stage I breast-cancer patients not treated with chemotherapy were examined. Mean time since treatment for the CMF patients was 5.1 years after the last CMF course, and for the control patients 3.6 years after termination of radiotherapy. An information processing task was administered with concurrent EEG registration. Reaction times and the amplitudes and latencies of an Event Related Potential component (P3) in different task conditions related to input, central, and output processing of information were studied. Significant differences in latency and amplitude of the P3 component were found between the treatment groups with an earlier and reduced P3 in the chemotherapy group. Patients treated with chemotherapy had longer reaction times (although not significantly different) than the control group on all task conditions. Our data provide further evidence for long-term neurocognitive problems in breast-cancer patients treated with adjuvant (CMF) chemotherapy and offer new information regarding abnormalities in brain functioning in these patients.

    @@ Traditional Chinese medicine (TCM) has been used to treat diseases including cancer in China for several thousand years. TCM holds that the pathogenesis of cancer lies mainly in deficiency of vital qi, accumulation of cold, stagnation of qi, obstruction of phlegm, blood stasis, retention of toxic heat, and that the therapeutic principles for cancer should be mainly to strengthen body resistance and restore normal function (mainly by strengthening the spleen and nourishing the kidney), to warm yang and disperse cold, to soothe the liver and regulate qi circulation, to resolve phlegm and dispel retained water, to promote blood circulation and remove blood stasis, to clear away heat and remove toxicity, to resolve hard mass and to treat malignant or poisoning diseases with poisonous drugs.

    Few studies have reported reproductive outcomes after breast cancer chemotherapy. The relationship between anti-Müllerian hormone (AMH) concentrations and the occurrence of subsequent pregnancies in women after chemotherapy for breast cancer was investigated. Women aged 18-43 years treated with chemotherapy for invasive breast cancer between May 2005 and January 2011 were retrospectively identified. Exclusion criteria were previous gonadotoxic treatment, oophorectomy or hysterectomy. Measurement of AMH took place before, during chemotherapy and at distant time points after the end of chemotherapy (4 months to 5.5 years). Seventeen out of 134 patients experienced 28 spontaneous pregnancies (median follow-up: 59 months). Neither baseline AMH (divided into quartiles) nor end-of-chemotherapy AMH (detectable versus undetectable) were significantly associated with the occurrence of pregnancy. Chemotherapy regimen with anthracyclines was associated with a greater probability of pregnancy compared with a taxane-containing regimen (hazard ratio 4.75; (95% CI 1.76 to 12.8); P = 0.002). Five-year disease-free survival and overall survival rates were 60% (95% CI: 51 to 70; relapse, n = 48) and 88% (95% CI 82 to 95; deaths, n = 21), respectively. AMH did not predict the occurrence of pregnancy. Additional studies assessing ovarian reserve and reproductive outcomes after breast cancer are required.

    Bone is a hormonally responsive organ. Sex hormones and calcium regulating hormones, including parathyroid hormone, 1-25 dihydroxy vitamin D, and calcitonin, have effects on bone resorption and bone deposition. These hormones affect both bone quality and bone quantity. The sex hormone estrogen inhibits bone resorption, and estrogen therapy has been developed to prevent and treat osteoporosis. Androgens are an important source of estrogen through the action of the enzyme aromatase and may themselves stimulate bone formation. Hence, the sex steroids play a role in bone metabolism. Breast cancer and prostate cancer are frequently hormonally responsive and may be treated with antiestrogens or antiandrogens respectfully. In addition, chemotherapy and supportive medications may alter the patient's endocrine system. In general, the suppression of sex hormones has a predictable affect on bone health, as seen by loss of bone mineral density and increased risk of fragility fractures. The bone toxicity of cancer-directed endocrine therapy can be mitigated through screening, counseling on optimization of calcium and vitamin D intake, exercise, and other lifestyle/behavioral actions, as well as the use of medications when the fracture risk is high. Maintaining bone health in patients who are treated with endocrine therapy for breast and prostate cancer is the focus of this review.

IOP (8 am, 10 am, and 4 pm was measured at baseline and weeks 2, 6, and 12. Subgroup analysis of the FCBT PF arm assessed changes in average eye IOP from baseline in treatment-naïve vs previously treated patients. To evaluate the effect of treatment status at baseline (treatment-naïve vs previously treated on IOP reduction in the FCBT PF treatment group, an analysis of covariance model was used with treatment status and investigator as fixed effects, and baseline average eye IOP, age, glaucoma diagnosis, and baseline average eye corneal thickness as covariates. P-values and the 95% confidence intervals were determined using the model.Results: In the FCBT PF arm, IOP mean changes from baseline ranged from -8.7 mmHg to -9.8 mmHg in treatment-naïve patients (N=50, compared with -7.3 mmHg to -8.5 mmHg in previously treated patients (N=228. Baseline IOP, age, glaucoma diagnosis, and corneal thickness significantly affected IOP reduction in the FCBT PF group. Adjusting for these covariates, FCBT PF had a greater IOP-lowering effect (0.8–1.7 mmHg in treatment-naïve patients than previously treated patients

    The purpose of this study was to observe the effects of autonomic nerve pharmacopuncture (ANP) treatment on cancer-related fatigue (CRF) in patients with advanced cancer. This observational case study was conducted at the East West Cancer Center of Daejeon University's Dunsan Korean Medical Hospital. Two patients were observed. One patient was diagnosed with left thymic cancer metastatic to the left pleura. The other patient had terminal-stage cervical cancer with iliac bone and lumbar 5 metastases. We injected mountain ginseng pharmacopuncture (MGP) into acupoints alongside the spine (Hua-Tuo-Jia-Ji-Xue, EX B2). We examined the patients for CRF using the Korean version of the Revised Piper Fatigue Scale (RPFS-K), which is a self-assessment tool. The scores on the RPFS-K for both patients tended to decrease during the treatment. Laboratory findings, including hematological changes, were also checked. Liver and renal function tests showed that the treatment was safe. Although further large-population studies are necessary, this case study suggests that ANP has a favorable effect on CRF in patients with advanced cancer.

    Some organochlorine pesticides (OCs) have been individually linked to breast cancer (BC) because they exert oestrogenic effects on mammary cells. However, humans are environmentally exposed to more or less complex mixtures of these organochlorines, and the biological effects of these mixtures must be elucidated. In this work we evaluated the in vitro effects exerted on human BC cells by the OC mixtures that were most frequently detected in two groups of women who participated in a BC case–control study developed in Spain: healthy women and women diagnosed with BC. The cytotoxicity, oestrogenicity, and androgenicity of the most prevalent OC mixtures found in healthy women (H-mixture) and in BC patients (BC-mixture) were tested at concentrations that resembled those found in the serum of the evaluated women. Our results showed that both OC mixtures presented a similar oestrogenic activity and effect on cell viability, but BC-mixture showed an additional anti-androgenic effect. These results indicate that although the proliferative effect exerted by these mixtures on human breast cells seems to depend mainly on their oestrogenic action, the BC-mixture might additionally induce cell proliferation due to its anti-androgenic activity, therefore increasing the carcinogenic potential of this mixture. The findings of this study demonstrate that subtle variations in the composition of a mixture may induce relevant changes in its biological action. - Highlights: • E-screen and A-screen of two mixtures of organochlorine pesticides (OCP) • Assay concentrations based on a previous breast cancer case–control study • Only non-cytotoxic concentrations assayed • Both OCP mixtures induce proliferation mediated by oestrogen receptor. • OCP mixture of breast cancer patients exhibits additional androgenic activity.

    The purpose of this study was to determine whether epirubicin, cisplatin and infused 5FU (ECF) improves overall survival (OS) compared to 5FU, etoposide and leucovorin (FELV) in patients with previously untreated advanced biliary cancer in a prospective randomised study. Patients were randomly assigned to receive epirubicin, cisplatin and infused 5FU ECF or bolus 5FU etoposide and leucovorin (FELV). The primary end point was OS with secondary end points of objective response rate (ORR), failure-free survival (FFS), quality of life (QOL) and toxicity. In all, 54 patients were recruited with 27 randomly assigned to each arm. The median OS for ECF was 9.02 months (95% confidence interval (CI): 6.46-11.51) and FELV 12.03 months (95% CI: 9.3-14.7), P=0.2059. Objective response rates were similar for both arms: ECF 19.2% (95% CI: 6.55-39.3); FELV 15% (95% CI: 3.2-37.9), P=0.72. There was significantly increased grade 3/4 neutropenia with FELV vs ECF (53.8 vs 29.5%, respectively, P=0.020). Symptom resolution was impressive for both regimens. This is the largest reported randomised study to date in this setting. ECF did not improve OS compared to FELV, but was associated with less acute toxicity. These data suggest that chemotherapy can prolong OS and achieve good symptomatic relief in advanced biliary cancer.

    Full Text Available Abstract Background This retrospective survey describes types of cancers diagnosed in HIV-infected subjects in Asia, and assesses risk factors for cancer in HIV-infected subjects using contemporaneous HIV-infected controls without cancer. Methods TREAT Asia HIV Observational Database (TAHOD sites retrospectively reviewed clinic medical records to determine cancer diagnoses since 2000. For each diagnosis, the following data were recorded: date, type, stage, method of diagnosis, demographic data, medical history, and HIV-related information. For risk factor analyses, two HIV-infected control subjects without cancer diagnoses were also selected. Cancers were grouped as AIDS-defining cancers (ADCs, and non-ADCs. Non-ADCs were further categorized as being infection related (NADC-IR and unrelated (NADC-IUR. Results A total of 617 patients were included in this study: 215 cancer cases and 402 controls from 13 sites. The majority of cancer cases were male (71%. The mean age (SD for cases was 39 (10.6, 46 (11.5 and 44 (13.7 for ADCs, NADC-IURs and NADCs-IR, respectively. The majority (66% of cancers were ADCs (16% Kaposi sarcoma, 40% non-Hodgkin's lymphoma, and 9% cervical cancer. The most common NADCs were lung (6%, breast (5% and hepatocellular carcinoma and Hodgkin's lymphoma (2% each. There were also three (1.4% cases of leiomyosarcoma reported in this study. In multivariate analyses, individuals with CD4 counts above 200 cells/mm3 were approximately 80% less likely to be diagnosed with an ADC (p Conclusions The spectrum of cancer diagnoses in the Asia region currently does not appear dissimilar to that observed in non-Asian HIV populations. One interesting finding was the cases of leiomyosarcoma, a smooth-muscle tumour, usually seen in children and young adults with AIDS, yet overall quite rare. Further detailed studies are required to better describe the range of cancers in this region, and to help guide the development of screening programmes.

    2012-03-01

    We present a salutary lesson learned from three cases with significant complications that followed anorectal intervention in the presence of radiation proctitis due to prior radiotherapy for adenocarcinoma of the prostate. After apparent routine rubber band ligation for painful haemorrhoids, one patient developed a colo-cutaneous fistula. Following laser coagulation for radiation proctitis, one patient required a pelvic exenteration for a fistula, while another developed a rectal stenosis. Those diagnosing and treating colonic conditions should be mindful of the increased prevalence of patients who have had radiotherapy for prostate cancer and the potential for complications in treating these patients.

    Of 1290 consecutive patients treated between 1992 and 2011 for primary squamous cell carcinoma of the oral cavity at a regional centre, 750 had died by August 2013. About half of them (n=373) died in hospital, 113 (15%) in a hospice, 180 (24%) at home, 57 (8%) in a care home, and 22 (3%) elsewhere. Cancer was the underlying cause of death in 64%, and of them, 56% were oral cancers. The place of death was strongly associated with the age at death and cancer being the underlying cause. The percentage of people who died from cancer at home or in a hospice rose over time across all age groups and, from 2010, accounted for two-thirds. In contrast, less than 1 in 5 who did not die from cancer, died at home or in a hospice, and in this there has been no discernible change over the last 20 years. The percentage of deaths from cancer in hospital and hospice ranged from 32%-38% and 20%-29%, respectively, across age groups. An increase in the number of deaths from cancer in care homes in those aged 75 years and over was mirrored by fewer at home. Most of those who did not die from cancer, died in hospital, two-thirds were under 65 years, 85% were aged 65-84, and 56% were older. This was mirrored by fewer deaths at home in those under 85 and more in care homes in those over 75. In conclusion, our findings suggest that patients' preferences not to die in hospital are being realised. However, at the end of their lives, patients and their carers need more support at home, and more research is required.

    Full Text Available This case report is aimed to investigate the effects of Korean medicine therapy (KMT including oral herbal medicine and herb nebulizer therapy in treating metastatic bladder cancer in the lungs. A 74-year-old man was diagnosed with metastatic bladder cancer in both lungs in August 2013. He refused any chemotherapy and was admitted to our hospital in a much progressed state on January 11, 2014. Since then, he was treated with KMT until May 17, 2014. The main oral herbal medicines were Hyunamdan made of heat-processed ginseng, Hangamdan S made of Cordyceps militaris, Panax ginseng radix, Commiphora myrrha, calculus bovis, margarita, Boswellia carteri, Panax notoginseng radix and Cremastra appendiculata tuber, and nebulizer therapy with Soram nebulizer solution made of wild ginseng and Cordyceps sinensis distillate. Their effect was evaluated considering the change of the main symptoms and using serial chest X-ray. The size and number of multiple metastatic nodules in both lungs were markedly decreased and the symptoms had disappeared. These results suggest that KMT can be an effective method to treat metastatic bladder cancer in the lungs.

    Purpose: To examine the accuracy of clinical staging and its effects on outcome in bladder cancer (BC) patients treated with radical cystectomy (RC), using a large national database. Methods and Materials: A total of 16,953 patients with BC without distant metastases treated with RC from 1998 to 2009 were analyzed. Factors associated with clinical–pathologic stage discrepancy were assessed by multivariate generalized estimating equation models. Survival analysis was conducted for patients treated between 1998 and 2004 (n=7270) using the Kaplan-Meier method and Cox proportional hazards models. Results: At RC 41.9% of patients were upstaged, whereas 5.9% were downstaged. Upstaging was more common in females, the elderly, and in patients who underwent a more extensive lymphadenectomy. Downstaging was less common in patients treated at community centers, in the elderly, and in Hispanics. Receipt of preoperative chemotherapy was highly associated with downstaging. Five-year overall survival rates for patients with clinical stages 0, I, II, III, and IV were 67.2%, 62.9%, 50.4%, 36.9%, and 27.2%, respectively, whereas those for the same pathologic stages were 70.8%, 75.8%, 63.7%, 41.5%, and 24.7%, respectively. On multivariate analysis, upstaging was associated with increased 5-year mortality (hazard ratio [HR] 1.80, P<.001), but downstaging was not associated with survival (HR 0.88, P=.160). In contrast, more extensive lymphadenectomy was associated with decreased 5-year mortality (HR 0.76 for ≥10 lymph nodes examined, P<.001), as was treatment at an National Cancer Institute–designated cancer center (HR 0.90, P=.042). Conclusions: Clinical–pathologic stage discrepancy in BC patients is remarkably common across the United States. These findings should be considered when selecting patients for preoperative or nonoperative management strategies and when comparing the outcomes of bladder sparing approaches to RC.

    The HAP nanoparticles were synthesized with a chemical co-precipitation method. It was monodispersed in needle shape. Its average diameter was 30 nm and length was 70 am. Human liver cancer cells and normal hepatic cells were treated by hydroxyapatite nanoparticles. SR-XRF analysis was used to detect the content variation of calcium and phosphor elements in cancer cells when the cells were treated by hydroxyapatite nanoparticles. It was introduced to reveal the anti-cancer mechanism of HAP nanoparticles. Experiments verified that the contents of calcium and phosphor elements in hepatocellular carcinoma had been obviously increased after the cells were treated by hydroxyapatite nanoparticles. And the contents increased with hydroxyapatite concentration and treatment time increasing. The Ca/P molar ratio in treated cell was different from both that in hydroxyapatite and that in untreated cancer cell. Apatite nanoparticles evidently altered the calcium and phosphor environments in treated hepatocellular carcinoma cells. That finally halted the proliferation of carcinoma cells.

    We investigated the outcome and the prognostic factors of patients with locally advanced esophageal cancer who were treated with concurrent chemo-radiotherapy. Two hundred forty six patients with esophageal cancer that were treated by radiotherapy between January 1994 and July 2007. Of these, 78 patients who received radiotherapy of {>=}45 Gy with concurrent chemotherapy were retrospectively enrolled in this study. We included patients stages IIA, IIB, III, IVA, and IVB with supraclavicular metastasis in the middle/lower esophageal cancer or celiac node metastasis in cervical or upper/middle thoracic esophageal cancer. The median radiation dose was 54 Gy and the combination chemotherapy with 5-FU and cisplatin (FP chemotherapy) was given concurrently with radiotherapy in most patients (88%). The follow-up period ranged from 2 to 117 months (median 14 months). The treatment response of the 54 patients could be evaluated by computerized tomography or endoscopy. A complete response (CR) was observed in 17 patients, whereas a partial response was observed in 18 patients. In patients with a CR, the median recurrence time was 20 months and the first relapse sites constituted a locoregional failure in 3 patients and a distant failure in 7 patients. The 1-, 2-, and 5-year overall survival (OS) rates were 58.9%, 21.7%, and 12.2%, respectively. The median survival period was 14 months. A univariate analysis indicated that the treatment response and cycles of FP chemotherapy were significant prognostic factors for OS. Daily or weekly administration of cisplatin as a radiosensitizer showed a better treatment response than FP chemotherapy. This study has shown that results of concurrent chemo-radiotherapy in patients with locally advanced esophageal cancer is comparable to those of other studies. Daily or weekly cisplatin administration may be considered as an alternative treatment in patients that are medically unfit for FP chemotherapy.

    There is increasing evidence that metformin, a commonly used treatment for diabetes, might have the potential to be repurposed as an economical and safe cancer therapeutic. The aim of this study was to determine whether stage III-IV or recurrent endometrial cancer patients who are using metformin during treatment with chemotherapy have improved survival. To test this we analyzed a retrospective cohort of subjects at two independent institutions who received chemotherapy for stage III-IV or recurrent endometrial cancer from 1992 to 2011. Diagnosis of diabetes, metformin use, demographics, endometrial cancer clinico-pathologic parameters, and survival duration were abstracted. The primary outcome was overall survival. The final cohort included 349 patients, 31 (8.9%) had diabetes and used metformin, 28 (8.0%) had diabetes but did not use metformin, and 291 (83.4%) did not have diabetes. The results demonstrate that the median overall survival was 45.6 months for patients with diabetes who used metformin compared to 12.5 months for patients with diabetes who did not use metformin and 28.5 months for patients without diabetes (log-rank test comparing the three groups P = 0.006). In a model adjusted for confounders, the difference in survival between the three groups remained statistically significant (P = 0.023). The improvement in survival among metformin users was not explained by better baseline health status or more aggressive use of chemotherapy. Overall, the findings in this retrospective cohort of endometrial cancer patients with stage III-IV or recurrent disease treated with chemotherapy indicate that patients with diabetes who were concurrently treated with metformin survived longer than patients with diabetes who did not use metformin.

    Full Text Available BACKGROUND: Tamoxifen significantly improves outcome for estrogen receptor-positive (ER+ breast cancer, but the 15-year recurrence rate remains 30%. The aim of this study was to identify gene profiles that accurately predicted the outcome of ER+ breast cancer patients who received adjuvant Tamoxifen mono-therapy. METHODOLOGY/PRINCIPAL FINDINGS: Post-menopausal breast cancer patients diagnosed no later than 2002, being ER+ as defined by >1% IHC staining and having a frozen tumor sample with >50% tumor content were included. Tumor samples from 108 patients treated with adjuvant Tamoxifen were analyzed for the expression of 59 genes using quantitative-PCR. End-point was clinically verified recurrence to distant organs or ipsilateral breast. Gene profiles were identified using a model building procedure based on conditional logistic regression and leave-one-out cross-validation, followed by a non-parametric bootstrap (1000x re-sampling. The optimal profiles were further examined in 5 previously-reported datasets containing similar patient populations that were either treated with Tamoxifen or left untreated (n = 623. Three gene signatures were identified, the strongest being a 2-gene combination of BCL2-CDKN1A, exhibiting an accuracy of 75% for prediction of outcome. Independent examination using 4 previously-reported microarray datasets of Tamoxifen-treated patient samples (n = 503 confirmed the potential of BCL2-CDKN1A. The predictive value was further determined by comparing the ability of the genes to predict recurrence in an additional, previously-published, cohort consisting of Tamoxifen-treated (n = 58, p = 0.015 and untreated patients (n = 62, p = 0.25. CONCLUSIONS/SIGNIFICANCE: A novel gene expression signature predictive of outcome of Tamoxifen-treated patients was identified. The validation suggests that BCL2-CDKN1A exhibit promising predictive potential.

    DDX3 belongs to DEAD box RNA helicase family and is involved in the progression of several types of cancer. In this work, we employed a High Throughput Virtual screening approach to identify bioactive compounds against DDX3 from ZINC natural database. Ketorolac salt was selected based on its binding free energy less than or equals to -5 Kcal/mol with reference to existing synthetic DDX3 inhibitors and strong hydrogen bond interactions as similar to crystallized DDX3 protein (2I4I). The anti-cancer activity of Ketorolac salt against DDX3 was tested using oral squamous cell carcinoma (OSCC) cell lines. This compound significantly down regulated the expression of DDX3 in human OSCC line (H357) and the half maximal growth inhibitory concentration (IC50) of Ketorolac salt in H357 cell line is 2.6 µM. Ketorolac salt also inhibited the ATP hydrolysis by directly interacting with DDX3. More importantly, we observed decreased number of neoplastic tongue lesions and reduced lesion severity in Ketorolac salt treated groups in a carcinogen induced tongue tumor mouse model. Taken together, our result demonstrates that Ketorolac salt is a newly discovered bioactive compound against DDX3 and this compound can be used as an ideal drug candidate to treat DDX3 associated oral cancer.

    Full Text Available Objective. To elucidate the optimum preoperative biliary drainage method for patients with pancreatic cancer treated with neoadjuvant chemotherapy (NAC. Material and Methods. From January 2010 through December 2014, 20 patients with borderline resectable pancreatic cancer underwent preoperative biliary drainage and NAC with a plastic or metallic stent and received NAC at Hiroshima University Hospital. We retrospectively analyzed delayed NAC and complication rates due to biliary drainage, effect of stent type on perioperative factors, and hospitalization costs from diagnosis to surgery. Results. There were 11 cases of preoperative biliary drainage with plastic stents and nine metallic stents. The median age was 64.5 years; delayed NAC occurred in 9 cases with plastic stent and 1 case with metallic stent (p=0.01. The complication rates due to biliary drainage were 0% (0/9 with metallic stents and 72.7% (8/11 with plastic stents (p=0.01. Cumulative rates of complications determined with the Kaplan-Meier method on day 90 were 60% with plastic stents and 0% with metallic stents (log-rank test, p=0.012. There were no significant differences between group in perioperative factors or hospitalization costs from diagnosis to surgery. Conclusions. Metallic stent implantation may be effective for preoperative biliary drainage for pancreatic cancer treated with NAC.

    Ovarian cancer is the most lethal disease among the malignant tumors of female reproductive organs. Few successful therapeutic options exist for patients with ovarian cancer. The common therapeutic methods are surgical operation, chemotherapy, radiotherapy, and combination of these treatments. In recent years, studies have indicated that Pinellia pedatisecta Schott (PPS), a traditional Chinese medicine, could inhibit tumor growth. In this study, we demonstrated that PPS extract could induce apoptosis in SKOV3 cells in a dose- and time-dependent manner. We further conducted transcriptome sequencing on PPS extract-treated SKOV3 cells along with controls, and identified 1,754 transcripts whose expression differs at least 3-fold over the controls. These differentially expressed transcripts include the apoptosis-related genes such as the caspase family members, and were significantly enriched in steroid biosynthesis in the KEGG pathway database compared with the transcriptome background. Most of the differentially expressed transcripts from this pathway were upregulated in PPS extract-treated cell line, indicating that PPS extract-induced apoptosis was accompanied by increased steroid biosynthesis (e.g. zymosterol). These results suggest that PPS extract could be a new cytostatic therapeutic agent for ovarian cancer.

    The first case of primary lung cancer in a transplanted lung was described in 2001. Since then, only 5 cases of lung cancer in donated lung have been reported. We present one more patient with non-small cell cancer in the transplanted lung treated with stereotactic body radiation therapy. In most cases of primary lung cancer in transplanted lung, rapid progression of the cancer was reported. Occurrence of the locoregional failure in our case could be explained by factors related to the treatment protocol and also to underlying immunosuppression.

    We evaluated the failure pattern of the celiac axis, gastric lymph node, and treatment outcome in the upper and mid-esophageal region of cancer patients treated by definitive radiotherapy, except when treating the celiac axis and gastric lymph node for treatment volume, retrospectively. Materials and Methods: The study constituted the evaluation 108 patients with locally advanced esophageal cancer receiving radiotherapy or a combination of radiotherapy and chemotherapy at Chonbuk National University Hospital from January 1986 to December 2006. In total, 82 patients treated by planned radiotherapy, except when treating the celiac axis and gastric lymph node for treatment volume, were analysed retrospectively. The study population consisted of 78 men and 2 women (mean age of 63.2 years). In addition, 51 patients received radiotherapy alone, whereas 31 patients received a combination of radiation therapy and chemotherapy. The primary cancer sites were located in the upper portion (17 patients), and mid portion (65 patients), respectively. Further, the patients were in various clinical stages including T1N0-1M0 (7 patients), T2N0-1M0 (18 patients), T3N0-1M0 (44 patients) and T4N0-1M0 (13 patients). The mean follow up period was 15 months. Results: The various treatment outcomes included complete response (48 patients), partial response (31 patients) and no response (3 patients). The failure patterns of the lymph node were comprised of the regional lymph node (23 patients) and the distance lymph node which included celiac axis and gastric lymph node (13 patients). However, metastasis was not observed in the regional and distant lymph node in 10 patients, whereas 36 patients were not evaluated. Furthermore, of the 13 patients who developed celiac axis and gastric lymph node metastases, 3 were in stage T1N0-1M0 and 10 were in stage T2-4N0-1M0. A complete response appeared in 12 patients, whereas a partial response appeared in 1 patient. The mean survival time of the

    Taliglucerase alfa is a β-glucosidase enzyme replacement therapy (ERT) approved in the US and other countries for the treatment of Gaucher disease (GD) in adults and is approved in pediatric and adult patients in Australia and Canada. It is the first approved plant cell-expressed recombinant human protein. A Phase 3, multicenter, open-label, 9-month study assessed safety and efficacy of switching to taliglucerase alfa in adult and pediatric patients with GD treated with imiglucerase for at least the previous 2years. Patients with stable disease were offered taliglucerase alfa treatment using the same dose (9-60U/kg body weight) and regimen of administration (every 2weeks) as imiglucerase. This report summarizes results from 26 adult and 5 pediatric patients who participated in the trial. Disease parameters (spleen and liver volumes, hemoglobin concentration, platelet count, and biomarker levels) remained stable through 9months of treatment in adults and children following the switch from imiglucerase. All treatment-related adverse events were mild or moderate in severity and transient in nature. Exploratory parameters of linear growth and development showed positive outcomes in pediatric patients. These findings provide evidence of the efficacy and safety profile of taliglucerase alfa as an ERT for GD in patients previously treated with imiglucerase. This trial was registered at www.clinicaltrials.gov as # NCT00712348.

    Full Text Available Abstract Background Many studies have reported an increased risk of developing a second primary malignancy (SPM of the breast in women treated for thyroid cancer. In this study, we investigated several potential risk factors for this association. The aim of this retrospective cohort study was to identify a subgroup of women surgically treated for papillary thyroid cancer that may benefit from more careful breast cancer screening. Methods A total of 101 women surgically treated for papillary thyroid cancer from 1996 to 2009 with subsequent follow-up were interviewed by phone regarding personal risk factors and lifestyle habits. Only 75 questionnaires could be evaluated due to a 25.7% rate of patients not retrieved or refusing the interview. Data analysis was performed using a multivariate logistic model. Results The standardised incidence ratio (SIR for breast cancer was 3.58 (95% IC 1.14 - 8.37. Our data suggest a protective effect of multiparity on the development of a SPM of the breast (O.R. 0.15; 95% IC 0.25 - 0.86. Significant associations were not found with other known risk factors including Body Mass Index (BMI, age at first tumour, concurrent metabolic diseases, smoking, physical activity and familiarity. Conclusions This study confirms that a higher incidence of SPM of the breast is observed in women treated for papillary thyroid cancer. Additionally, this risk is increased by nulliparity, thus a strict breast screening program for nulliparous women treated for thyroid cancer may be advisable.

    Directory of Open Access Journals (Sweden)

    2015-11-01

    Full Text Available Scott W. Lowe is currently principal investigator at the Memorial Sloan-Kettering Cancer Center. After beginning his studies in chemical engineering, he decided to take another path and became fascinated by biochemistry, genetics and molecular biology, which ultimately led to an interest in human disease, particularly cancer. During his PhD at the Massachusetts Institute of Technology (MIT, Scott had the opportunity to benefit from the exceptional mentorship of Earl Ruley, David Housman and Tyler Jacks, and contributed to elucidating how the p53 (TP53 tumor suppressor gene limits oncogenic transformation and modulates the cytotoxic response to conventional chemotherapy. This important work earned him a fellowship from the Cold Spring Harbor Laboratory, which helped to launch his independent career. Scott is now a leading scientist in the cancer field and his work has helped to shed light on mechanisms of cell apoptosis and senescence to better understand and treat cancer. In this interview, he talks about this incredible scientific journey.

    This descriptive and case-control study was carried out in a pediatric oncology outpatient clinic to determine the school-related physical, social, and psychological problems and problems experienced in academic achievement of children treated for cancer. The sample of the study consisted of 56 Turkish patients with cancer, aged 7-18 years, who were in remission and attending school as well as their parents, a control group of patients who did not have cancer, and their teachers. A Child Information Form, a Child Health Questionnaire Parent's Form of 50 questions, a Behavior Evaluation Scale for Children, and Young People and a Teacher's Report Form were used as data collection tools in the study. Of the children, 30.3% experienced various physical difficulties stemming from cancer therapy that affected their school life. The number of late enrollments, the number of children repeating a grade, and the rates of school absenteeism were also found to be higher in the survivors than in the controls.

    BAX326 is a recombinant factor IX (rFIX; nonacog gamma) manufactured without the addition of any materials of human or animal origin, and with two viral inactivation steps (solvent/detergent treatment and 15 nm nanofiltration). The aim of this prospective trial was to investigate the pharmacokinetics, haemostatic efficacy and safety of BAX326 in previously treated patients aged 12-65 years with severe or moderately severe haemophilia B. BAX326 was safe and well tolerated in all 73 treated subjects; adverse events considered related to treatment (2.7% incidence, all non-serious) were transient and mild, and no hypersensitivity reactions, inhibitor formation or thrombotic events were observed. Pharmacokinetic (PK) equivalence (n = 28) between BAX326 and a licensed rFIX was confirmed in terms of the ratio of geometric mean AUC(0-72) h per dose. Twice-weekly prophylaxis [mean duration 6.2 (±0.7) months; 1.8 (±0.1) infusions per week, 49.5 (±4.8) IU kg(-1) per infusion] was effective in preventing bleeding episodes, with a significantly lower (79%, P < 0.001) annualized bleed rate (4.2) compared to an on-demand treatment in a historical control group (20.0); 24 of 56 subjects on prophylaxis (43%) did not bleed throughout the study observation period. Of 249 total acute bleeds, 211 (84.7%) were controlled with one to two infusions of BAX326. Haemostatic efficacy at resolution of bleed was rated excellent or good in 96.0% of all treated bleeding episodes. The results of this study indicate that BAX326 is safe and efficacious in treating bleeds and routine prophylaxis in patients aged 12 years and older with haemophilia B.

    2008-01-01

    Cetuximab is a new medication that has recently been approved for the treatment of advanced colorectal cancer. To date we have had tittle experience in using this targeted agent. Eleven patients in our hospital with advanced colorectal cancer were treated with cetuximab and chemotherapy. Based on the curative effect of this combination therapy, we have concluded that the following nursing practices make an important contribution to the patients' prognosis and wellbeing: to establish a good nurse-patient relationship, to increase patient understanding of the side effects, to standardize the medications, to observe and to deal with the side effects of the medications(for example skin reaction, neutropenia, and diarrhea), and to provide continuous mental health care support and education.

    Childhood cancer survivors (CCS) treated with anthracyclines are at risk for cardiomyopathy. This case series evaluated the response of anthracycline exposed CCS with subclinical cardiomyopathy to aerobic and strength training. Body composition, strength and cardiopulmonary fitness were evaluated before and after the 12-week intervention. All equipment and materials were provided to five 10+ year CCS (3 males, mean age 38.0 ± 3.3 years) for a guideline-based home exercise program. All five completed the study with no adverse events. Compliance with exercise was 86%. These results suggest that exercise training may improve exercise capacity of CCS with subclinical cardiomyopathy.

    The goal of this study was to establish the feasibility of sentinel node biopsy in patients with recurrent prostate cancer after initial local treatment and to compare lymphatic drainage patterns of the treated versus untreated prostate. In ten patients with a proven local recurrence after initial local treatment (four external beam radiation, four brachytherapy and two high-intensity focused ultrasound), the radiotracer ({sup 99m}Tc-nanocolloid, GE Healthcare) was injected into the prostate. Planar images after 15 min and 2 h were followed by SPECT/CT (Symbia T, Siemens) to visualize lymphatic drainage. Laparoscopic sentinel lymphadenectomy was assisted by a gamma probe (Europrobe, EuroMedical Instruments) and a portable gamma camera (Sentinella, S102, Oncovision). Sentinel node identification and lymphatic drainage patterns were compared to a consecutive series of 70 untreated prostate carcinoma patients from our institute. Lymphatic drainage was visualized in all treated patients, with a median of 3.5 sentinel nodes per patient. Most sentinel nodes were localized in the pelvic area, although the percentage of patients with a sentinel node outside the pelvic para-iliac region (para-aortic, presacral, inguinal or near the ventral abdominal wall) was high compared to the untreated patients (80 versus 34%, p = 0.01). In patients with recurrent prostate cancer, 95% of the sentinel nodes could be harvested and half of the patients had at least one positive sentinel node on pathological examination. Lymphatic mapping of the treated prostate appears feasible, although sentinel nodes are more frequently found in an aberrant location. Larger trials are needed to assess the sensitivity and therapeutic value of lymphatic mapping in recurrent prostate cancer. (orig.)

    This study aimed to investigate whether glucose transporter-1 (GLUT-1) expression in a pretreatment esophageal cancer biopsy was predictive of clinical outcomes in patients with esophageal cancer undergoing concurrent chemoradiotherapy (CRT). A total of 25 patients with esophageal cancer treated with concurrent CRT were reviewed. Radiotherapy was administered up to total doses of 40-66.6 Gy (median 66.6 Gy) with a single fraction of 1.8-2 Gy. Regarding chemotherapy, cisplatin (80 mg/m(2) on day 1) and 5-fluorouracil (800 mg/m(2) on days 2-6) were used concurrently with radiotherapy, every 3-4 weeks for a total of 1-2 courses. Tissue samples from esophageal carcinoma were obtained from the 25 patients by biopsy prior to concurrent CRT, and a semiquantitative analysis of GLUT-1 expression was performed using immunohistochemical staining. High GLUT-1 expression was observed in 7 of 25 (28%) patients, and GLUT-1 expression was significantly correlated with clinical T stage (p=0.0454), clinical N stage (p=0.0324) and initial response to CRT (p=0.0185). Patients with a high GLUT-1 expression had significantly poorer local control (LC) (5-year LC 28.6%) than those with a low expression (5-year LC 73.4%, pGLUT-1 and the number of chemotherapy courses were independent prognostic factors for LC. Patients with a high GLUT-1 expression had significantly lower recurrence-free survival (RFS) compared to those with a low GLUT-1 expression (p=0.0405). Multivariate analysis revealed that GLUT-1, the number of chemotherapy courses and clinical M stage were independent prognostic factors for RFS. GLUT-1 expression was significantly correlated with clinical T stage, clinical N stage and initial response to concurrent CRT, and was predictive of LC and RFS for patients with esophageal cancer treated with concurrent CRT.

    2017-02-01

    Background: Possible targeted therapies for metastatic triple negative breast cancer (TNBC) include cytotoxic chemotherapy that causes interstrand breaks (platinum-based drugs). The excision repair cross-complementation 1 (ERCC1) enzyme plays an essential role in the nucleotide excision repair pathway, removing platinum-induced DNA adducts and contributing to cisplatin resistance. Detecting ERCC1 overexpression is important in considering treatment options for metastatic TNBC, including individualized approaches to therapy, and may facilitate improved responses or reduction of unnecessary toxicity. We hypothesized that assigning cisplatin based on pretreatment ERCC1 expression would improve response and survival. This study was conducted to assess the impact of ERCC1 expression on PFS, OS and response rates in metastatic triple negative breast cancer patients treated with platinum-based chemotherapy. Methods: From June 2012 to November 2013, 52 metastatic triple negative breast cancer patients were enrolled. ERCC1 protein expression was detected from pretreatment biopsies by Immunohistochemistry. All patients received cisplatin plus paclitaxel. The primary end point was the impact of ERCC1 expression on PFS and OS. Results: 34 patients (65.4%) showed positive ERCC1 expression while 18 (34.6%) proved negative. Positive ERCC1 expression was associated with short PFS (median, 5 months vs. 7 months; P = 0.043), short OS (median, 9 months vs. 11 months; P = 0.033) and poor response to cisplatin based chemotherapy (P = 0.046). Conclusions: This prospective study further validated ERCC1 as a reliable biomarker for customized chemotherapy in metastatic triple negative breast cancer patients. High expression of ERCC1 was thereby fond to be significantly associated with poor outcome in patients treated with platinum based chemotherapy.

    Objective To investigate the clinical effect and the overall survival (OS) rate of patients with advanced non-small cell lung cancer (NSCLC) who have undergone Wheel Balance Cancer Therapy (WBCT). Methods The cases of 33 patients with advanced NSCLC who were treated with WBCT at the East West Cancer Center (EWCC) between October 4, 2004, and October 3, 2013, without undergoing concurrent conventional treatment were analyzed. The Kaplan-Meier method was used to estimate the OS of the cases, and the median OS was calculated according to age, Eastern Cooperative Oncology Group Performance Status (ECOG PS), conventional-treatment history, WBCT treatment duration, and histological tumor type. Results The median OS of all patients was 31.1 (95% confidence interval [CI] = 3.5-58.7) months; the OS rates were 63.6% and 24.2% at years 1 and 2, respectively. The median OS rates of patients under and over 65 years were 45.2 (95% CI = 13.5-76.9) and 19.5 (95% CI = 7.1-31.8) months, respectively (P = .189). The median OS rates of patients who received WBCT for >14 days but treatment and those who had not were 45.2 (95% CI = 9.1-81.3) and 3.9 (95% CI = unable to calculate) months, respectively (P = .000). The median OS rates of patients with squamous cell carcinoma (SCC) and non-SCC lung cancer were 5.6 (95% CI = unable to calculate) and 45.2 (95% CI = 9.1-81.3) months, respectively (P = .262). The median OS rate of patients with ECOG PS ≥3 was 14.3 (95% CI = 8.8-19.8) months; that of patients ECOG PS treatment and have an ECOG PS <3.

    2011-09-01

    The curative approach to oesophageal cancer carries significant risks and a cure is achieved in approximately 20 per cent. There has been a recent trend internationally to observe improved operative and oncological outcomes. This report audits modern outcomes from a high volume centre with a prospective database for the period 2004-08. 603 patients were referred and 310 (52%) were treated with curative intent. Adenocarcinoma represented 68% of the cohort, squamous cell cancer 30%. Of the 310 cases, 227 (73%) underwent surgery, 105 (46%) underwent surgery alone, and 122 (54%) had chemotherapy or combination chemotherapy and radiation therapy. The postoperative mortality rate was 1.7%. The median and 5-year survival of the 310 patients based on intention to treat was 36 months and 36%, respectively, and of the 181 patients undergoing R0 resection, 52 months and 42%, respectively. An in-hospital postoperative mortality rate of less than 2 per cent, and 5-year survival of between 35 and 42% is consistent with benchmarks from international series.

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

    C-fibres probably represent the common final pathway in both ACE inhibitors and neoplastic cough. A recent report demonstrated that inhaled sodium cromoglycate is an effective treatment for ACE inhibitors' cough; this effect might be due to the suppression of afferent unmyelinated C-fibres. We tested the hypothesis that inhaled sodium cromoglycate might also be effective in lung cancer patients who presented with irritative neoplastic cough. Twenty non-small-cell lung cancer (NSCLC) patients complaining of cough resistant to conventional treatment were randomised to receive, in a double-blind trial, either inhaled sodium cromoglycate or placebo. Patients recorded cough severity daily, before and during treatment, on a 0 to 4 scale. The efficacy of treatment was tested with the Mann-Whitney U-test for non-parametric measures, comparing the intergroup differences in the measures of summary of symptom scores calculated in each patient before and after treatment. We report that inhaled sodium cromoglycate can reduce cough, also in NSCLC patients and that such reduction, observed in all patients treated, is statistically significant (P < 0.001). Inhaled sodium cromoglycate appears to be a cost-effective and safe treatment for lung cancer-related cough. PMID:8688342

    The purpose of the study is to determine the relationship between radiation-induced complications with dosimetric and radiobiological parameters for prostate cancer patients that underwent the conformal radiotherapy treatment. 17 prostate cancer patients that have been treated with conformal radiotherapy were retrospectively analysed. The dosimetric data was retrieved in the form of dose-volume histogram (DVH) from Radiotherapy Treatment Planning System. The DVH was utilised to derived Normal Tissue Complication Probability (NTCP) in radiobiological data. Follow-up data from medical records were used to grade the occurrence of acute gastrointestinal (GI) and genitourinary (GU) complications using Radiation Therapy Oncology Group (RTOG) scoring system. The chi-square test was used to determine the relationship between radiation-induced complication with dosimetric and radiobiological parameters. 8 (47%) and 7 (41%) patients were having acute GI and GU complications respectively. The acute GI complication can be associated with V60{sub rectum}, rectal mean dose and NTCP{sub rectum} with p-value of 0.016, 0.038 and 0.049 respectively. There are no significant relationships of acute GU complication with dosimetric and radiobiological variables. Further study can be done by increase the sample size and follow up duration for deeper understanding of the factors that effecting the GU and GI complication in prostate cancer radiotherapy.

    Four-hundred fifty-one patients with bladder cancer, 348 men and 103 women, were treated by radiation therapy and/or radical cystectomy during the last two decades at Memorial Sloan-Kettering Cancer Center. Radical cystectomy alone was the treatment in 98 men and 39 women. Radical radiation therapy to an average tumor dose of 6,000 rad in six weeks was given to 79 men and 30 women +/- one year before salvage cystectomy was done for recurrent or persistent tumors. Planned preoperative irradiation was delivered to the true pelvis either 4,000 rad in four weeks in 95 men and 24 women or 2,000 rad in one week in 76 men and 10 women +/- six weeks and two days, respectively, before radical cystectomy. Over-all survival and recurrence results in both sexes were similar, 40 per cent of men and 36 per cent of women were alive at five years without recurrence, 45 per cent of men and 48 per cent of women died in five or more years with local and/or distant recurrences, and 21 per cent of men and 15 per cent of women died before five years from causes other than cancer recurrence. Higher five-year survival for high clinical stage B2 to D1 tumors was noted similarly in the irradiated men (30 per cent) and women (37 per cent) than in the cystectomy alone patients (19 per cent in men and 4 per cent in women). Similar survival rates (52 to 57 per cent) were observed in men and women with low clinical stage O to B1 tumors treated with or without irradiation.

    Full Text Available Although suicide among childhood cancer survivors is rare, there is still a significantly higher risk in this population than in healthy adolescents. A 17-year-old girl cured of Burkitt lymphoma committed suicide after completing her treatment. She had never previously shown signs of psychological suffering and was in good general health. This case made the operators wonder how this tragic possibility might be prevented. It is essential for the ongoing monitoring of the psychological and social suffering of young people during follow-up programs to be assured by a multidisciplinary team involved in the patient′s global care.

    The principle of the hypofractionation in radiotherapy is to deliver a higher dose by session and to reduce the duration of treatment. In the particular case of the cancer of prostate, a hypofractionned protocol allows to deliver an equivalent radiobiological dose identical even higher than a standard plan of irradiation. The hypofractionation is presented as a solution to improve the access to the care (fewer processing times by patient, more patients treated by machine) while increasing the quality of the care: better carcinologic control, less radiotoxicity. The objective of this article is to make a clarification on the hypofractionned radiotherapy in first intention in the treatment of the localized prostate cancer. We count three studies on large cohorts, comparing standard plans to 1.8-2 Gy/session and hypofractionned plans (2.5-3 Gy/session). The inferior carcinologic results of the two first comparative studies with regard to the study of phase I/II of the Cleveland clinic were owed to a sub-dosage of hypofractionned plans. The administered equivalent biological doses were lower than the at present recommended total doses and lower than the theoretical doses, calculated on the bases of an erroneous evaluation of the radiosensibility of the prostate cancer. In the comparative study of Arcangeli, the rate of survival without biological recurrence in 4 years (82%) was significantly to the advantage of the hypofractionned group, while reducing the duration of treatment of 3 weeks. Four comparative studies reported aigues/late toxicity, gastrointestinal (GI)/genito-urinary acceptable (GU) even lower with a hypofractionned plan. The hypofractionation is potentially the future of the radiotherapy in the treatment of the localized prostate cancer thanks to the technological innovation, but for all that does not constitute at present a standard.

  11. DNA Damage and Repair Biomarkers in Cervical Cancer Patients Treated with Neoadjuvant Chemotherapy: An Exploratory Analysis.

    Full Text Available Cervical cancer cells commonly harbour a defective G1/S checkpoint owing to the interaction of viral oncoproteins with p53 and retinoblastoma protein. The activation of the G2/M checkpoint may thus become essential for protecting cancer cells from genotoxic insults, such as chemotherapy. In 52 cervical cancer patients treated with neoadjuvant chemotherapy, we investigated whether the levels of phosphorylated Wee1 (pWee1, a key G2/M checkpoint kinase, and γ-H2AX, a marker of DNA double-strand breaks, discriminated between patients with a pathological complete response (pCR and those with residual disease. We also tested the association between pWee1 and phosphorylated Chk1 (pChk1, a kinase acting upstream Wee1 in the G2/M checkpoint pathway. pWee1, γ-H2AX and pChk1 were retrospectively assessed in diagnostic biopsies by immunohistochemistry. The degrees of pWee1 and pChk1 expression were defined using three different classification methods, i.e., staining intensity, Allred score, and a multiplicative score. γ-H2AX was analyzed both as continuous and categorical variable. Irrespective of the classification used, elevated levels of pWee1 and γ-H2AX were significantly associated with a lower rate of pCR. In univariate and multivariate analyses, pWee1 and γ-H2AX were both associated with reduced pCR. Internal validation conducted through a re-sampling without replacement procedure confirmed the robustness of the multivariate model. Finally, we found a significant association between pWee1 and pChk1. The message conveyed by the present analysis is that biomarkers of DNA damage and repair may predict the efficacy of neoadjuvant chemotherapy in cervical cancer. Further studies are warranted to prospectively validate these encouraging findings.

    Radiotherapy (RT) is considered as the best treatment for early laryngeal cancer in terms of survival and preservation of voice. Quality of life (QOL) must also be assessed after new treatments, such as laser treatment or laryngomicrosurgery. The QOL after RT was assessed in 61 patients (57 men and 4 women) with histologically proven laryngeal or hypopharyngeal cancer (glottis T1-2, 48 : supraglottis 11 : hypopharynx, 2). Cobalt-60 gamma rays were emitted via lateral opposed portals that included the glottis/larynx area. The delivered dose was 53 to 70 Gy/23 to 35 Fr (median, 60 Gy/30 Fr). Assessment was done by interview of physicians at periodic follow-up examinations of patients. The census period was June to December 1990. Patients` ages ranged from 37 to 82 years (median, 62 years) at treatment and 38 to 88 years (median, 68 years) at QOL assessment. Most patients enjoyed the similar daily activities and job status as before. Thirty-seven of 61 patients felt occasional hoarseness after RT, and 21 refrained from loud speech. All patients could use the telephone easily, except for one patient who had severe hearing loss. Many patients stopped smoking cigarettes, but most drank as before RT. There were no significant differences in lifestyle quality between less than and more than 5 years after RT. This QOL assessment is applicable to patients with laryngeal cancer. One half of patients treated by RT have symptoms compatible with chronic laryngitis. This study confirms that RT yields good QOL and voice quality for patients with laryngeal cancer. (author).

    Full Text Available BACKGROUND: Recent clinical trial results have suggested that programmed cell death ligand 1 (PD-L1 expression measured by immunohistochemistry may predict response to anti–programmed cell death 1 (PD-1 therapy. Results on the association between PD-L1 expression and survival among patients with advanced non–small cell lung cancer (NSCLC treated with chemotherapy are inconsistent. MATERIAL AND METHODS: We evaluated the relationship between PD-L1 expression and overall survival (OS among 204 patients with advanced NSCLC treated at Aarhus University Hospital, Aarhus, Denmark, from 2007 to 2012. PD-L1 expression was measured using a prototype immunohistochemistry assay with the anti–PD-L1 22C3 antibody (Merck. PD-L1 strong positivity and weak positivity were defined to be traceable to the clinical trial version of the assay. RESULTS: Twenty-five percent of patients had PD-L1 strong-positive tumors, and 50% had PD-L1 weak-positive tumors. No statistically significant association was found between PD-L1 expression and survival; adjusted hazard ratio of 1.34 (95% confidence interval, 0.88-2.03; median OS, 9.0 months for the PD-L1 strong-positive group and 1.07 (0.74-1.55; median OS, 9.8 months for the PD-L1 weak-positive group compared with the PD-L1–negative group (median OS, 7.5 months. No association was seen between PD-L1 expression and OS when PD-L1 expression levels were stratified by median or tertiles. CONCLUSIONS: In concordance with previous studies, we found PD-L1 measured by immunohistochemistry to be frequently expressed in patients with advanced NSCLC. However, PD-L1 expression is not a strong prognostic marker in patients with advanced NSCLC treated with chemotherapy.

    Full Text Available The high incidence of tumor recurrence following transurethral resection (TUR represents a major problem encountered in the management of bladder cancer. This study examined the efficacy of intravesical chemotherapy in superficial bladder cancer. We retrospectively analyzed 90 Japanese cases with low-grade superficial transitional cell carcinoma (stage T1, grades 1 and 2 who were rendered tumor-free by TURBT (TUR of bladder tumor and who thereafter were treated with or without intravesical chemotherapy. Among them, instillation was terminated in 2 patients due to adverse effects (severe but reversible chemical cystitis. Remaining 88 patients were divided into 2 groups according to therapy: the TURBT-only group (n=46, defined as patients treated with TURBT alone, and the Instillation group (n=42, defined as patients treated with weekly intravesical instillation therapies using epirubicin plus Ara-C. Recurrence-free rate was significantly higher in the Instillation group than in the TURBT-only group (p=0.02, HR = 0.457. The 5-year recurrence-free rate was 58.5% for the Instillation group and 38.6% for the TURBT-only group. Our instillation schedule represents the most intensive regimen among previously reported therapies and resulted in a 54.3% decrease in incidence of tumor recurrence. We believe that the results of this study could provide useful information on management of bladder cancer.

    Objective: The aim of our study was to investigate if common toxicities are correlated to objective response rate (ORR) in metastatic colorectal cancer (mCRC) patients treated by irinotecan based regimens. Methods: Univariate and multivariate logistic regression analyses were performed to evaluate correlations between common toxicities and binary ORR in 106 mCRC patients from a prospective cohort treated with irinotecan based regimens. Results: The most frequent severe toxicities (Grade 3/4) were as follows: neutropenia (27.4%), diarrhea (16.9%), leucopenia (12.6%), vomiting (3.2%) and thrombocytopenia (2.1%). Thrombocytosis was observed in 25 (26.3%) patients. ORR was 25.3%. Thrombocytopenia (P = 0.014), line of chemotherapy (P = 0.028) and thrombocytosis (P = 0.033) were correlated with ORR in univariate analysis. In multivariate analysis, thrombocytopenia (odds ratio [OR] = 8.600, 95% confidence interval [CI] = 1.705–43.385, P = 0.009) and first line chemotherapy (OR = 5.155, 95% CI = 1.153–23.256, P = 0.032) positively related to ORR. Conclusion: Throm-bocytopenia may be an indicator of ORR in mCRC patients treated by irinotecan plus 5-fluorouracil/capecitabine. Evidence is not strong enough to prove that irinotecan based regimens-induced diarrhea, leucopenia, neutropenia or vomiting is associ-ated with ORR.

    Erlotinib is an epidermal growth factor receptor inhibitor prescribed to patients with locally advanced or metastasized non-small cell lung carcinoma after failure of at least one earlier chemotherapy treatment. Approximately 75% of the patients treated with erlotinib develop acneiform skin rashes. A patient treated with erlotinib 3 months after finishing concomitant treatment with chemotherapy and radiotherapy for non-small cell lung cancer is presented. Unexpectedly, the part of the skin that had been included in his previously radiotherapy field was completely spared from the erlotinib-induced acneiform skin rash. The exact mechanism of erlotinib-induced rash sparing in previously irradiated skin is unclear. The underlying mechanism of this phenomenon needs to be explored further, because the number of patients being treated with a combination of both therapeutic modalities is increasing. The therapeutic effect of erlotinib in the area of the previously irradiated lesion should be assessed. (orig.)

    Highlights: Black-Right-Pointing-Pointer Sal sensitizes antimitotic drugs-treated cancer cells. Black-Right-Pointing-Pointer Sal sensitizes them by prevention of G2 arrest and reduced cyclin D1 levels. Black-Right-Pointing-Pointer Sal also sensitizes them by increasing DNA damage and reducing p21 level. Black-Right-Pointing-Pointer A low concentration of Sal effectively sensitized the cancer cells to antimitotic drugs. -- Abstract: Here, we investigated whether Sal could sensitize cancer cells to antimitotic drugs. We demonstrated that Sal sensitized paclitaxcel (PAC)-, docetaxcel (DOC)-, vinblastin (VIN)-, or colchicine (COL)-treated cancer cell lines, suggesting that Sal has the ability to sensitize the cells to any form of microtubule-targeting drugs. Sensitization to the antimitotic drugs could be achieved with very low concentrations of Sal, suggesting that there is a possibility to minimize Sal toxicity associated with human cancer patient treatments. Sensitization by Sal increased apoptosis, which was observed by C-PARP production. Sal sensitized the cancer cells to antimitotic drugs by preventing G2 arrest, suggesting that Sal contributes to the induction of mitotic catastrophe. Sal generally reduced cyclin D1 levels in PAC-, DOC-, and VIN-treated cells. In addition, Sal treatment increased pH2AX levels and reduced p21 levels in antimitotic drugs-treated cells. These observations suggest that the mechanisms underlying Sal sensitization to DNA-damaging compounds, radiation, and microtubule-targeting drugs are similar. Our data demonstrated that Sal sensitizes cancer cells to antimitotic drugs by increasing apoptosis through the prevention of G2 arrest via conserved Sal-sensitization mechanisms. These results may contribute to the development of Sal-based chemotherapy for cancer patients treated with antimitotic drugs.

    Objective We studied the ef icacy of salvage hepatectomy for treating recurrent hepatic cancer after radiofrequency ablation (RFA). Methods A retrospective analysis of 67 patients who had recurrent liver cancer after RFA treatment and received salvage hepatectomy in the Department of Hepatobiliary Surgery, Southwest Hospital, Third Mili-tary Medical University (China), from January 2006 to January 2014, was performed. The analysis included patient gender, age, hepatitis type, alpha-fetoprotein (AFP), and TNM stage prior to RFA and salvage hepatectomy, overal survival rates, and tumor-free survival rates after salvage hepatectomy. Results Among the 67 patients, there were 57 cases of hepatitis B, two cases of hepatitis C, and eight cases did not have hepatitis. AFP levels in patients ranged from 3 to 4521 ng/mL (median 33 ng/mL). Before RFA, 54 cases were stage I tumors, and 13 were stage II tumors. Tumor sizes varied from 0.82 to 4.83 cm (median 3.0 cm). In 20 cases, one RFA was performed, and for 47 cases, RFA was repeated. RFA-ablated region diameters ranged from 3.8 to 5.2 cm (median 4.5 cm). The interval between the salvage surgical resection and RFA was 3–37 months. Before salvage hepatectomy, 23 stage I tumors, 12 stage II tumors, and 32 stage III tumors were present (size ranged 4.83–11.84 cm; median 6.3 cm). For salvage hepatectomy, laparotomy was performed for 56 cases, and laparoscopy was performed for 28 cases. Inflow clamping was performed for 39 cases (15–45 min). Surgery was 219–370 min and intraoperative blood loss was 100–2100 mL. For 13 cases, intraoperative blood transfusion was required. Tumor pathological data revealed 31, 35, and 1 poorly, moderately, and wel dif erentiated tumors, respectively. No patients died due to operative complications, and hospital stays were 8–10 days. Overal and tumor-free survival rates were 85% and 79% for 1 year, 50% and 20% for 3 years, and 39% and 19% for 5 years, respectively. Kaplan-Meier analysis

    Background The phase III RAINBOW trial demonstrated that the addition of ramucirumab to paclitaxel improved overall survival, progression-free survival, and tumor response rate in fluoropyrimidine–platinum previously treated patients with advanced gastric/gastroesophageal junction (GEJ) adenocarcinoma. Here, we present results from quality-of-life (QoL) and performance status (PS) analyses. Patients and methods Patients with Eastern Cooperative Oncology Group PS of 0/1 were randomized to receive ramucirumab (8 mg/kg i.v.) or placebo on days 1 and 15 of a 4-week cycle, with both arms receiving paclitaxel (80 mg/m2) on days 1, 8, and 15. Patient-reported outcomes were assessed with the QoL/health status questionnaires EORTC QLQ-C30 and EQ-5D at baseline and 6-week intervals. PS was assessed at baseline and day 1 of every cycle. Time to deterioration (TtD) in each QLQ-C30 scale was defined as randomization to first worsening of ≥10 points (on 100-point scale) and TtD in PS was defined as first worsening to ≥2. Hazard ratios (HRs) for treatment effect were estimated using stratified Cox proportional hazards models. Results Of the 665 patients randomized, 650 (98%) provided baseline QLQ-C30 and EQ-5D data, and 560 (84%) also provided data from ≥1 postbaseline time point. Baseline scores for both instruments were similar between arms. Of the 15 QLQ-C30 scales, 14 had HR < 1, indicating similar or longer TtD in QoL for ramucirumab + paclitaxel. Treatment with ramucirumab + paclitaxel was also associated with a delay in TtD in PS to ≥2 (HR = 0.798, P = 0.0941). Alternate definitions of PS deterioration yielded similar results: PS ≥ 3 (HR = 0.656, P = 0.0508), deterioration by ≥1 PS level (HR = 0.802, P = 0.0444), and deterioration by ≥2 PS levels (HR = 0.608, P = 0.0063). EQ-5D scores were comparable between treatment arms, stable during treatment, and worsened at discontinuation. Conclusion In patients with previously treated advanced gastric

    Abstract Biologics has been widely used in the treatment of rheumatoid arthritis. We aimed to determine whether etanercept, a TNF-α inhibitor (TNFi) that is used to treat patients with rheumatoid arthritis (RA), affects cancer risk. This retrospective matched cohort study used data in the Registry of Catastrophic Illness Database in Taiwan from January 1, 1996 to December 31, 2010. RA, all-cancer, and solid cancer were defined using International Classification of Disease codes (ICD-9-CM 714.X, 140–208, and 140–199, respectively). Cox proportional hazard modeling was used to estimate the hazard ratio (HR) of cancer in all TNFi-treated RA patients, with a focus on the risk in the etanercept-treated patients, after adjusting for comorbidities and concomitant medication. In this Taiwanese dataset, there were 1111 TNFi-treated RA patients and 16,812 RA patients who were naive to all biologics identified. Among the 1002 pairs of etanercept-treated and biologic-naive patients who were matched 1-to-1 for age, gender, RA duration, methotrexate-use, and index date of TNFi prescription, the mean age was 48.9 ± 15.0 years. The highest proportion of patients was in the age subgroup of 30 to 60 years (63.8%). Most patients (77.2%) were women. The mean RA duration before etanercept treatment was 2.0 ± 1.5 years. During a mean 2.1 years of observation, etanercept was associated with significant risk reduction for all-cancer (HR 0.59, 0.36–0.98) and solid cancer (HR 0.46, 0.27–0.79) relative to the matched biologic-naive patients. The current study explored the safety profile of TNFi and identified a potential benefit of etanercept on the incidence of all-cancer and solid cancer in RA patients. PMID:28207513

Although chemotherapy improves the prognosis of the patients with gastrointestinal cancers, some patients do not benefit from therapy and are exposed to the adverse effects. The polymorphisms in genes including GSTM1 and GSTT1 have been explored to predict therapeutic efficacy; however, the results were inconsistent and inconclusive. Materials and methods: A systematic review and meta-analysis was performed by searching relevant studies about the association between the GSTM1 and GSTT1 polymorphisms and chemotherapy efficacy in gastrointestinal cancers in databases such as PubMed, EMBASE, Web of Science, Chinese National Knowledge Infrastructure, and Wanfang database up to January 10, 2016. Subgroup analyses were also performed according to ethnicity, cancer type, evaluation criteria, study type, chemotherapy type, and age. Results: A total of 19 articles containing 3,217 cases were finally included. Overall analysis suggested that no significance was found between overall toxicity, neurotoxicity, neutropenia, gastrointestinal toxicity, tumor response, and progression-free survival, and the polymorphisms in GSTM1 and GSTT1, while GSTM1 polymorphism associated with overall survival (OS; hazard ratio =1.213, 95% confidence interval =1.060–1.388, P=0.005. Subgroup analyses suggested that neurotoxicity was associated with GSTM1 polymorphism in the Asian population, neutropenia was associated with GSTM1 polymorphism in palliative

    Currently, studies in Drosophila melanogaster has shown emerging evidence that microgravity stimuli can be detected at the genetic level. Analysis of the transcriptome in the pupal stage of the fruit flies under microgravity conditions versus ground controls has suggested the presence of a few candidate genes as "gravity sensors" which are experimentally validated. Additionally, several studies have shown that microgravity causes inhibitory effects in different types of cancer cells, although the genes involved and responsible for these effects are still unknown. Here, we demonstrate that the genes suggested as the sensors of gravitational waves in Drosophila melanogaster and their human counterpart (orthologous genes) are highly involved in carcinogenesis, proliferation, anti-apoptotic signals, invasiveness, and metastatic potential of breast cancer cell tumors. The transcriptome analyses suggested that the observed inhibitory effect in cancer cells could be due to changes in the genetic expression of these candidates. These results encourage the possibility of new therapeutic targets managed together and not in isolation.

    PURPOSE: For patients with germ cell cancer, various pulmonary toxicity risk factors have been hypothesized for treatment with bleomycin, etoposide, and cisplatin (BEP).

    Full Text Available Abstract Background There is scant information on whether Human Immunodeficiency Virus (HIV seropositivity has an influence on the outcome of treatment of precancerous cervical lesions using cryotherapy. We studied the prevalence of cervical abnormalities detectable by visual inspection and cervical lesions diagnosed by colposcopy according to HIV serostatus and described the outcomes of cryotherapy treatment. Methods Trained nurses examined women not previously screened for cervical cancer using visual inspection with acetic acid (VIA and Lugol's iodine (VILI in two family planning/post natal clinics in Kampala, Uganda, from February 2007 to August 2008. Women with abnormal visual inspection findings were referred for colposcopic evaluation and HIV testing. Women with precancerous cervical lesions detected at colposcopy were treated mainly by cryotherapy, and were evaluated for treatment outcome after 3 months by a second colposcopy. Results Of the 5 105 women screened, 834 presented a positive screening test and were referred for colposcopy. Of these 625 (75% returned for the colposcopic evaluation and were tested for HIV. For the 608 (97.5% women in the age range 20-60 years, colposcopy revealed 169 women with cervical lesions: 128 had inflammation, 19 had low grade squamous intraepithelial lesion (LGSIL, 13 had high grade squamous intraepithelial lesion (HGSIL, 9 had invasive cervical cancer and 2 had inconclusive findings. Detection rates per 1 000 women screened were higher among the older women (41-60 years compared to women aged 20-40 years. They were accordingly 55% and 20% for inflammation, 10% and 2% for LGSIL, 5% and 2% for HGSIL, 6% and 1% for invasive cervical cancer. Of the 608 women, 103 (16% were HIV positive. HIV positivity was associated with higher likelihood of inflammation (RR = 1.7; 95% CI: 1.2-2.4. Conclusions Detection rates were higher among older women 41-60 years.

    To determine whether neoadjuvant androgen deprivation therapy (NADT) improves clinical outcomes in patients with prostate cancer treated with definitive radiotherapy. We retrospectively reviewed medical records of 201 patients with prostate cancer treated with radiotherapy between January 1991 and December 2008. Of these, 156 patients with more than 3 years of follow-up were the subjects of this study. The median duration of follow-up was 91.2 months. NADT was given in 103 patients (66%) with median duration of 3.3 months (range, 1.0 to 7.7 months). Radiation dose was escalated gradually from 64 Gy to 81 Gy using intensity-modulated radiotherapy technique. Biochemical relapse-free survival (BCRFS) and overall survival (OS) of all patients were 72.6% and 90.7% at 5 years, respectively. BCRFS and OS of NADT group were 79.5% and 89.8% at 5 years and those of radiotherapy alone group were 58.8% and 92.3% at 5 years, respectively. Risk group (p = 0.010) and radiation dose > or =70 Gy (p = 0.017) affected BCRFS independently. NADT was a significant prognostic factor in univariate analysis, but not in multivariate analysis (p = 0.073). Radiation dose > or =70 Gy was only an independent factor for OS (p = 0.007; hazard ratio, 0.261; 95% confidence interval, 0.071-0.963). NADT prior to definitive radiotherapy did not result in significant benefit in terms of BCRFS and OS. NADT should not be performed routinely in the era of dose-escalated radiotherapy.

    The KRAS oncogene was among the first genetic alterations in colorectal cancer (CRC) to be discovered. Moreover, KRAS somatic mutations might be used for predicting the efficiency of anti-epidermal growth factor receptor therapeutic drugs. Because the KRAS mutations are similar in the primary CRC and/or the CRC metastasis, KRAS mutation testing can be performed on both specimen types. The purpose of this study was to investigate the clinical advantage of using a KRAS pathway-associated molecule analysis chip to analyze CRC patients treated with cetuximab. Our laboratory developed a KRAS pathway-associated molecule analysis chip and a weighted enzymatic chip array (WEnCA) technique, activating KRAS detection chip, which can detect KRAS mutation status by screening circulating cancer cells in the bloodstream. We prospectively enrolled 210 stage II-III CRC patients who received adjuvant oxaliplatin plus infusional 5-fluorouracil/leucovorin (FOLFOX)-4 chemotherapy with or without cetuximab. We compared the chip results of preoperative blood specimens with disease control status in these patients. Among the 168 CRC patients with negative chip results, 119 were treated with FOLFOX-4 plus cetuximab chemotherapy, and their relapse rate was 35.3 % (42/119). In contrast, the relapse rate was 71.4 % among the patients with negative chip results who received FOLFOX-4 treatment alone (35/49). Negative chip results were significantly correlated with better treatment outcomes in the FOLFOX-4 plus cetuximab group (P chip is a potential tool for predicting clinical outcomes in CRC patients following FOLFOX-4 treatment with or without cetuximab therapy.

    Purpose: The purpose of this study was to evaluate the prognostic significance of p16 immunohistochemistry (IHC) in patients with advanced cervical cancer treated with radiation therapy. Materials and Methods: This was a retrospective study of 126 patients with International Federation of Gynecology and Obstetrics Stages Ib1-IVb cervical cancer treated with radiation. Concurrent cisplatin chemotherapy was given to 108 patients. A tissue microarray (TMA) was constructed from the paraffin-embedded diagnostic biopsy specimens. Immunoperoxidase staining was performed on the TMA and a p16 monoclonal antibody was utilized. IHC p16 extent was evaluated and scored in quartiles: 0 = no staining, 1 = 1-25% of cells staining, 2 = 26 to 50%, 3 = 51 to 75%, and 4 = 76 to 100%. Results: The p16 IHC score was 4 in 115 cases, 3 in 1, 2 in 3 and 0 in 7. There was no relationship between p16 score and tumor histology. Patients with p16-negative tumors were older (mean age at diagnosis 65 vs. 52 years for p16-positive tumors; p = 0.01). The 5-year cause-specific survivals were 33% for p16-negative cases (score = 0) compared with 63% for p16-positive cases (scores 1, 2, 3 or 4; p = 0.07). The 5-year recurrence-free survivals were 34% for those who were p16-negative vs. 57% for those who were p16-positive (p = 0.09). In addition, patients with p16-positive tumors (score > 0) were more likely to be complete metabolic responders as assessed by the 3-month posttherapy 18 [F]-fluorodeoxyglucose positron emission tomography (FDG-PET)/computed tomograph compared with patients with p16-negative tumors (p = 0.03). Conclusion: p16 expression is predictive of improved survival outcome after chemoradiation therapy for advanced-stage invasive cervical carcinoma. Further testing will be needed to evaluate p16-negative cervical tumors.

    This work presents an estimation of the neutron dose distribution for common bladder cancer cases treated with high-energy photons of 15 MV therapy accelerators. Neutron doses were measured in an Alderson phantom, using TLD 700 and 600 thermoluminescence dosimeters, resembling bladder cancer cases treated with high-energy photons from 15 MV LINAC and having a treatment plan using the four-field pelvic box technique. Thermal neutron dose distribution in the target area and the surrounding tissue was estimated. The sensitivity of all detectors for both gamma and neutrons was estimated and used for correction of the TL reading. TLD detectors were irradiated with a Co60 gamma standard source and thermal neutrons at the irradiation facility of the National Institute for Standards (NIS). The TL to dose conversion factor was estimated in terms of both Co60 neutron equivalent dose and thermal neutron dose. The dose distribution of photo-neutrons throughout each target was estimated and presented in three-dimensional charts and isodose curves. The distribution was found to be non-isotropic through the target. It varied from a minimum of 0.23 mSv/h to a maximum of 2.07 mSv/h at 6 cm off-axis. The mean neutron dose equivalent was found to be 0.63 mSv/h, which agrees with other published literature. The estimated average neutron equivalent to the bladder per administered therapeutic dose was found to be 0.39 mSv Gy-1, which is also in good agreement with published literature. As a consequence of a complete therapeutic treatment of 50 Gy high-energy photons at 15 MV, the total thermal neutron equivalent dose to the abdomen was found to be about 0.012 Sv.

    Full Text Available Aim of the Study: Aim was to assess the clinical significance of the rate of tumor regression in carcinoma buccal mucosa undergoing radical radiotherapy. Materials and Methods: Sixty six patients were enrolled in the study with proven buccal cancers requiring radical radiotherapy, from 1990 to 1996. Radiotherapy was delivered using a combination of external beam and brachytherapy with preloaded cesium 137 needles. The response to the radiation was assessed at the completion of external beam radiation and 6 weeks after brachytherapy. An analysis correlating various parameters influencing the long term disease free survival and overall survival was done. Results: Response assessed at the end of external beam radiation correlated strongly with the overall survival and the disease free interval (P=0.000. No other factor influenced the survival. Conclusion: The rate of the tumor regression can predict the overall outcome in patients with buccal cancers treated with radiation. Completion of the planned course of radiation in patients who do not show a substantial reduction in size by 4.5 weeks of conventional radiation does not improve the results.

    Between 1949 and 1971, 451 patients with bladder cancer were treated by radiation therapy and/or radical cystectomy at the Memorial Sloan-Kettering Cancer Center. Radical cystectomy alone was the treatment for 137 patients in Group 1. In Group 2, 109 patients received radiation therapy to an average tumor dose of 6000 rad in 6 weeks +- 1 year before radical cystectomy for persistent, recurrent or new lesions. Planned preoperative irradiation consisted of either 4000 rad in 4 weeks for 119 patients in Group 3, or 2000 rad in 1 week for 86 patients in Group 4, +- 6 weeks and 2 days, respectively, before radical cystectomy. The determinate over-all distant and/or local recurrence rate was 49% for Group 1 and 37 to 45% for Groups 2 to 4. Local recurrence alone occurred in 28% of Group 1 patients and 14 to 16% of those in Groups 2 to 4. Distant metastases developed in 21% of Group 1 patients and 22 to 28% of Group 2 to 4 patients. A reduced incidence of pelvic recurrence was associated with radiation-induced stage reduction for Group 2 to 4 clinically high and low stage tumors, especially when the histologic grade was high. Similar frequencies of extrapelvic metastases in the four groups were maintained in clinically low and high stage tumors of low or high histological grade.

  15. Pharmacological reactivation of p53 as a strategy to treat cancer.

    Zawacka-Pankau, J; Selivanova, G

    2015-02-01

    It has been confirmed through studies using the technique of unbiased sequencing that the TP53 tumour suppressor is the most frequently inactivated gene in cancer. This finding, together with results from earlier studies, provides compelling evidence for the idea that p53 ablation is required for the development and maintenance of tumours. Genetic reconstitution of the function of p53 leads to the suppression of established tumours as shown in mouse models. This strongly supports the notion that p53 reactivation by small molecules could provide an efficient strategy to treat cancer. In this review, we summarize recent advances in the development of small molecules that restore the function of mutant p53 by different mechanisms, including stabilization of its folding by Apr-246, which is currently being tested in a Phase II clinical trial. We discuss several classes of compounds that reactivate wild-type p53, such as Mdm2 inhibitors, which are currently undergoing clinical testing, MdmX inhibitors and molecules targeting factors upstream of Mdm2/X or p53 itself. Finally, we consider the clinical applications of compounds targeting p53 and the p53 pathway.

    Introduction: One of the most feared complications of childhood cancer treatment is second malignant neoplasms (SMNs). This study evaluates the incidence, risk factors and outcomes of SMNs in a tertiary paediatric oncology centre in Singapore. Materials and Methods: A retrospective review was conducted on patients diagnosed with childhood cancer under age 21 and treated at the National University Hospital, Singapore, from January 1990 to 15 April 2012. Case records of patients with SMNs were reviewed. Results: We identified 1124 cases of childhood cancers with a median follow-up of 3.49 (0 to 24.06) years. The most common primary malignancies were leukaemia (47.1%), central nervous system tumours (11.7%) and lymphoma (9.8%). Fifteen cases developed SMNs, most commonly acute myeloid leukaemia/myelodysplastic syndrome (n = 7). Median interval between the first and second malignancy was 3.41 (0.24 to 18.30) years. Overall 20-year cumulative incidence of SMNs was 5.3% (95% CI, 0.2% to 10.4%). The 15-year cumulative incidence of SMNs following acute lymphoblastic leukaemia was 4.4% (95% CI, 0% to 8.9%), significantly lower than the risk after osteosarcoma of 14.2% (95% CI, 0.7% to 27.7%) within 5 years (P <0.0005). Overall 5-year survival for SMNs was lower than that of primary malignancies. Conclusion: This study identified factors explaining the epidemiology of SMNs described, and found topoisomerase II inhibitor use to be a likely risk factor in our cohort. Modifications have already been made to our existing therapeutic protocols in osteosarcoma treatment. We also recognised the importance of other risk management strategies, including regular long-term surveillance and early intervention for detected SMNs, to improve outcomes of high risk patients.

    Numerous antiangiogenic agents are approved for the treatment of oncological diseases. However, almost all patients develop evasive resistance mechanisms against antiangiogenic therapies. Currently no predictive biomarker for therapy resistance or response has been established. Therefore, the aim of our study was to identify biomarkers predicting the development of therapy resistance in patients with hepatocellular cancer (n = 11), renal cell cancer (n = 7) and non-small cell lung cancer (n = 2). Thereby we measured levels of angiogenic growth factors, tumor perfusion, circulating endothelial cells (CEC), circulating endothelial progenitor cells (CEP) and tumor endothelial markers (TEM) in patients during the course of therapy with antiangiogenic agents, and correlated them with the time to antiangiogenic progression (aTTP). Importantly, at disease progression, we observed an increase of proangiogenic factors, upregulation of CEC/CEP levels and downregulation of TEMs, such as Robo4 and endothelial cell-specific chemotaxis regulator (ECSCR), reflecting the formation of torturous tumor vessels. Increased TEM expression levels tended to correlate with prolonged aTTP (ECSCR high = 275 days vs. ECSCR low = 92.5 days; p = 0.07 and for Robo4 high = 387 days vs. Robo4 low = 90.0 days; p = 0.08). This indicates that loss of vascular stabilization factors aggravates the development of antiangiogenic resistance. Thus, our observations confirm that CEP/CEC populations, proangiogenic cytokines and TEMs contribute to evasive resistance in antiangiogenic treated patients. Higher TEM expression during disease progression may have clinical and pathophysiological implications, however, validation of our results is warranted for further biomarker development.

    Objective: To guide the optimal selection among first-generation epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) in clinical practice.This review attempted to provide a thorough comparison among three first-generation EGFR-TKIs, namely icotinib,erlotinib, and gefitinib, with regard to their molecular structure, pharmacokinetic parameters, clinical data, adverse reactions, and contraindications.Data Sources: An electronic literature search of the PubMed database and Google Scholar for all the available articles regarding gefitinib,icotinib, and erlotinib in the English language from January 2005 to December 2014 was used.Study Selection: The search terms or keywords included but not limited to "lung cancer", "nonsmall cell lung cancer (NSCLC)","epidemiology", "EGFR", "TKIs", and "optimal selection".Results: As suggested by this review, even though the three first-generation EGFR-TKIs share the quinazoline structure, erlotinib had the strongest apoptosis induction activity because of its use of a different side-chain.The pharmacokinetic parameters indicated that both erlotinib and icotinib are affected by food.The therapeutic window of erlotinib is narrow, and the recommended dosage is close to the maximum tolerable dosage.Icotinib enjoys a wider therapeutic window, and its concentration in the blood is within a safe dosage range even if it is administered with food.Based on multiple large-scale clinical trials, erlotinib is universally applied as the first-line treatment.In marked contrast, icotinib is available only in China as the second-or third-line therapeutic approach for treating advanced lung cancer.In addition, it exhibits a similar efficacy but better safety profile than gefitinib.Conclusions: Although there is a paucity of literature regarding whether icotinib is superior to erlotinib, its superior toxicity profile, noninferior efficacy, and lower cost indicate that it is a better alternative for Chinese patients living with

    The purpose of this study was to determine the incidence rate of prostate cancer among men with erectile dysfunction (ED) treated with phosphodiesterase type 5 inhibitors (PDE-5i) over a 7-year period vs.men with ED of the same age and with similar risk factors who were not treated with PDE-5i.In a retrospective review of electronic medical records and billing databases between the years 2000 and 2006,men with ED between the ages of 50 and 69 years and no history of prostate cancer prior to 2000 were identified.These individuals were divided into two groups:2362 men who had treatment with PDE-5i,and 2612 men who did not have treatment.Demographic data in each group were compared.During the study period,97 (4.1%) men with ED treated with PDE-5i were diagnosed with prostate cancer compared with 258 (9.9%) men with ED in the non-treated group (P<00001).A higher percentage of African Americans were treated with PDE-5i vs.those who were not (10.5% vs.7.1%; P<0.0001).The PDE-5i group had lower documented diagnosis of elevated prostate-specific antigen (10.0% vs.13.1%; P=0.0008) and higher percentage of benign prostatic hyperplasia (38.4% vs.35.1%; P=0.0149).Men with ED treated with PDE-5i tended to have less chance (adjusted odds ratio:0.4; 95% confidence intervals:0.3-0.5; P<0.0001) of having prostate cancer.Our data suggest that men with ED treated with PDE-5i tended to have less of a chance of being diagnosed with prostate cancer.Further research is warranted.

    In 1993 the FDA approved the commercial sale of milk from rbGH treated cows. Despite this approval, there are a number of public health concerns that have arisen about the safety of this milk. Specifically, there is concern that this milk may increase the risk and rate of cancer. Milk from rbGH treated cows has elevated levels of IGF-1. Furthermore, some amount of IGF-1 from the milk is orally active in humans. IGF-1 has a strong association with a number of cancers including breast, prostate...

    Full Text Available Abstract Background Female genital tuberculosis is an uncommon disease that is rarely diagnosed in developed countries. Case presentation A 61-year-old postmenopausal woman who had undergone surgery and treated with adjuvant chemotherapy for infiltrating ductal carcinoma of the breast five years ago, presented with bloody vaginal discharge, fatigue, weight loss, and low grade fevers at night for two months. Histological examination of the endometrium, done based on the suspicion of a second primary cancer due to the tamoxifen therapy, revealed a granulomatous reaction. Liquid and solid mycobacterial cultures of the tissues were performed. Although the acid fast staining was negative, the liquid culture was positive for Mycobacterium tuberculosis. Involvement of other systems was not detected. The patient was treated with a three-drug antituberculosis regimen for 9 months and recovered fully. Conclusion Female genital tuberculosis is a rare but curable disease that should be included in the differential diagnosis of women with menstrual problems. Early diagnosis is important and may prevent unnecessary invasive procedures for the patient.

    OBJECTIVES. As vascular endothelial growth factor (VEGF) is expressed in ovarian cancer, we assessed the efficacy and safety of bevacizumab (a monoclonal antibody targeting VEGF) plus microtubule targeting agents for heavily pre-treated ovarian carcinoma patients. METHODS. We retrospectively reviewed 43 patients with recurrent epithelial ovarian carcinoma. Combined treatment included bevacizumab with paclitaxel in 32 (74%), docetaxel in 10 (23%), and vinorelbine in one (2.3%) patients, respectively. RESULTS. The median number of combined treatment was six cycles (range 1-29). On RECIST criteria, the objective response rate (ORR) was 40% (16% CR and 24% PR). Clinical benefit (complete response [CR] plus partial response [PR] and stable disease [SD] lasting ≥ 3 months) was 74% (CI95%: 46.7-77%). Median duration of treatment and overall survival were 3.9 months (range 0.2-14.4 months) and 20.1 months (CI95%: 13.8-20.1) respectively. No toxic death was reported. Grade 3-4 toxicity occurred in 30% of patients. Gastrointestinal perforations and fistula occurred in 3 (7%) and 6 (14%) patients, respectively. CONCLUSION. Although being active in terms of ORR, bevacizumab plus microtubule targeting agents - mainly taxanes - leads to a high rate of gastro-intestinal perforations and fistula in heavily pre-treated ovarian carcinoma patients.

    Breast cancer in young women has been shown to have an aggressive behavior and worse prognosis. Studies evaluating young women enrolled in clinical trials of neoadjuvant chemotherapy have shown that age is a determinant factor in the achievement of a pathological complete response (pCR). In this study, we sought to analyze the outcomes of young patients treated with neoadjuvant chemotherapy at a single institution. 1639 patients treated with neoadjuvant chemotherapy were included. 316 patients ≤40 years were compared with 1323 patients aged >40 years regarding the achievement of a pCR (defined as no invasive residual tumor in the breast or lymph nodes). Disease-free survival (DFS) and overall survival were compared between groups according to pCR status and subtype, defined by hormone receptor (HR) and HER2 status. Young women were more likely to have a pCR than their older counterparts (37.4 vs. 26.3 %, P world clinical setting, the achievement of a pCR was an independently significant protective factor for recurrence across all subtypes and ages, except for HR+, HER2- disease in young women.

    The objective of this project was to systematically determine the prevalence and consequences of pulmonary fibrosis in youth with thyroid carcinoma and lung metastases from Belarus who were treated with radioiodine ({sup 131}I). A total of 69 patients treated for juvenile thyroid carcinoma and lung metastasis with {sup 131}I were assessed. A group of 29 patients without lung metastases and prior {sup 131}I treatment served as controls. The assessments included a CT scan of the lungs, extensive pulmonary function testing and an incremental cycle test to volitional fatigue with measurements of oxygen uptake (V. O{sub 2}), oxygen saturation and alveolar-arterial difference in oxygen partial pressure ({delta}aaO{sub 2}). Five patients with lung metastases showed advanced pulmonary fibrosis on CT scans and also had poorer lung functions compared with the 62 patients with none or minor signs of fibrosis and the 29 controls. Furthermore, these five patients showed lower peak V.O{sub 2}, lower oxygen saturation at peak exercise and higher exercise {delta}aaO{sub 2}. They were younger at the time of cancer diagnosis and had received chemotherapy more frequently than youth with pulmonary metastases who did not develop fibrosis. One of the five patients subsequently died from pulmonary fibrosis. Following the Chernobyl catastrophe, about 7% of children treated with radioiodine for thyroid carcinoma and lung metastases displayed pulmonary fibrosis which was associated with functional impairments. Based on the characteristics of affected individuals, the number of radioiodine courses may have to be limited, especially in young children, and chemotherapy should be avoided. (orig.)

    Haemostatic management of haemophilia B patients undergoing surgery is critical to patient safety. The aim of this ongoing prospective trial was to investigate the haemostatic efficacy and safety of a recombinant factor IX (rFIX) (Bax326) in previously treated subjects (12-65 years, without history of FIX inhibitors) with severe or moderately severe haemophilia B, undergoing surgical, dental or other invasive procedures. Haemostatic efficacy was assessed according to a predefined scale. Blood loss was compared to the average and maximum blood loss predicted preoperatively. Haemostatic FIX levels were achieved peri- and postoperatively in 100% of subjects (n = 14). Haemostasis was 'excellent' intraoperatively in all patients and postoperatively in those without a drain, and 'excellent' or 'good' at the time of drain removal and day of discharge in those with a drain employed. Following the initial dose, the mean FIX activity level rose from 6.55% to 107.58% for major surgeries and from 3.60% to 81.4% for minor surgeries. Actual vs. predicted blood loss matched predicted intraoperative blood loss but was equal to or higher than (but less than 150%) the maximum predicted postoperative blood loss reflecting the severity of procedure and FIX requirements. There were no related adverse events, severe allergic reactions or thrombotic events. There was no evidence that BAX326 increased the risk of inhibitor or binding antibody development to FIX. BAX326 was safe and effective for peri-operative management of 14 subjects with severe and moderately severe haemophilia B.

    The purpose of this randomized controlled trial was to determine the effects of resistance training (RT) on markers of inflammation and immune function in breast cancer survivors. Thirty-nine breast cancer survivors were randomly assigned to a RT (n = 20) or control (n = 19) group. RT performed supervized exercise three times per week. Natural killer cell (NK) and natural killer T-cell (NKT) function, and markers of inflammation (serum TNF-α, IL-6, IL-10, and CRP) were measured before and after training. Changes in NK and NKT cell function were analyzed using ANCOVA, with the change score the dependent variable, and the baseline value of the same variable the covariate. Effect sizes (ES) were calculated via partial eta-squared. We found a significant reduction, and large associated ESs, in the RT group compared to the control group for change in NK cell expression of TNF-α (p = 0.005, ES = 0.21) and NKT cell expression of TNF-α (p = 0.04, ES = 0.12). No differences were observed in any serum marker. Significant improvements in all measurements of strength were found in RT compared to control (p < 0.001; large ESs ranging from 0.32 to 0.51). These data demonstrate that RT has a beneficial effect on the NK and NKT cell expression of TNF-α indicating that RT may be beneficial in improving the inflammatory profile in breast cancer survivors.

    Recently, two new classification systems for grading of urothelial neoplasms have been published. The objective of both was to avoid the overdiagnosis of cancer and to create better criteria for the grades. The WHO/ISUP classification of 1998 distinguishes papilloma, papillary urothelial neoplasm of low malignant potential (PUNLMP), low and high grade carcinomas, whereas the WHO 1999 system subdivides the high grade into grades II and III, and is otherwise identical. This note summarizes studies supporting the rationale of the two new systems, describes pattern recognition criteria for the grades, and highlights the homology between them.

    Brain metastasis (BM) is increasingly diagnosed in Her2 positive breast cancer (BC) patients. Lack of effective treatment to breast cancer brain metastases (BCBMs) is probably due to inability of the current therapeutic agents to cross the blood-brain barrier. The central nervous system (CNS) response rate in BCBM patients was reported to improve from 2.6%-6% (lapatinib) to 20%-65% (lapatinib in combination with capecitabine). Lapatinib is a poor brain penetrant. In this study, we evaluated the CNS penetration of capecitabine and hoped to interpret the mechanism of the improved CNS response from the pharmacokinetic (PK) perspective. Capecitabine does not have antiproliferative activity and 5-fluorouracil (5-FU) is the active metabolite. Capecitabine was orally administered to mouse returning an unbound brain-to-blood ratio (Kp,uu,brain) at 0.13 and cerebrospinal fluid (CSF)-to-unbound blood ratio (Kp,uu,CSF) at 0.29 for 5-FU. Neither free brain nor CSF concentration of 5-FU can achieve antiproliferative concentration for 50% of maximal inhibition of cell proliferation of 4.57 µM. BCBM mice were treated with capecitabine monotherapy or in combination with lapatinib. The Kp,uu,brain value of 5-FU increased to 0.17 in the brain tumor in the presence of lapatinib, which is still far below unity. The calculated free concentration of 5-FU and lapatinib in the brain tumor did not reach the antiproliferative potency and neither treatment showed antitumor activity in the BCBM mice. The CNS penetration of 5-FU in human was predicted based on the penetration in preclinical brain tumor, CSF, and human PK and the predicted free CNS concentration was below the antiproliferative potency. These results suggest that CNS penetration of 5-FU and lapatinib are not desirable and development of a true CNS penetrable therapeutic agent will further improve the response rate for BCBM.

    Background The combination of cisplatin and vinorelbine is an evidence-supported regimen for adjuvant chemotherapy for treating non-small cell lung cancer (NSCLC).But this doublet has considerable toxicity and unfavorable tolerability,and results in poor compliance.The cisplatin and gemcitabine regimen is one of the most active and well-tolerated regimens against advanced NSCLC,but its toxicity and tolerability has not been adequately evaluated in the adjuvant setting.Methods From a lung cancer database we retrospectively reviewed NSCLC patients receiving adjuvant chemotherapy of cisplatin (75 mg/m2) and gemcitabine (1250 mg/m2) between January 2005 and December 2011.Postoperative demographics,compliance to adjuvant therapy and toxicity were retrieved from medical records.Results A total of 132 patients met the criteria and were included in the study,96 were male (72.7%) and 36 were female (27.3%).Median age was 60.5 years old,range 29-75 years,and 41.7% of patients were ≥65 years old.Overall,68.2%patients received all four planned cycles,and the cumulative dose delivered for gemcitabine was 8333 mg (83.3% of the planned dose) and cisplatin 248 mg (82.7% of the planned dose).There were no treatment-related deaths.Grade 3/4neutropenia developed in 47 patients (35.6%) and was the predominant hematologic toxicity.Common grade 3/4 nonhematologic toxicities were nausea/vomiting (22.0%),infection (12.3%),and febrile neutropenia (11.4%).Conclusion Cisplatin and gemcitabine are feasible for use in the adjuvant setting with a favorable toxicity profile and superior tolerability compared with published data on cisplatin and vinorelbine.

    Objective: To assess the effect of temporary occlusion of hepatic blood inflow on hepatic cancer treated with diode-laser induced thermocogation (LITT). Methods: The carcinoma Walker-256 was implanted in 40 SD rat livers. Twelve days later, the animals were randomly divided into 4 groups. Group A received LITT alone; group B received hepatic artery temporary occlusion during LITT; group C received portal vein temporary occlusion during LITT; group D received hepatic artery and portal vein temporary occlusion during LITT. Tumors were exposed to 810 nm diode-laser light at 0.95 watts for 10 min from a scanner tip applicator placed in the tumor. At the same time, the intrahepatic temperature distribution in rats with liver tumors was measured per 2 min during thermocoagulation. Tumor control was examined immediately 7 and 14 d after thermocoagulation. Results:There was significant difference of intrahepatic temperature distribution in rats with liver tumors among the 4 groups (P<0.05)except when group C samples were compared with group D samples at each time point, and group B samples were compared with group C samples at 120 s (P>0.05). Light microscopic examination of the histologic section samples revealed three separate zones:regular hyperthermic coagulation necrosis zone, transition zone and reference zone. Compared with the samples in group A and group B, group C and group D samples had more clear margin among the three zones. Conclusion: The hepatic blood inflow occlusion, especially portal vein hepatic blood inflow occlusion, or all hepatic blood inflow occlusion considerably increased the efficacy of LITT in the treatment of liver cancer.

    Aromatase inhibitors (AI), either alone or together with chemotherapy, have become the standard adjuvant treatment for postmenopausal, estrogen receptor-positive (ER+) breast cancer. Although AIs improve overall survival, resistance is still a major clinical problem, thus additional biomarkers...... predictive of outcome of ER+ breast cancer patients treated with AIs are needed. Global gene expression analysis was performed on ER+ primary breast cancers from patients treated with adjuvant AI monotherapy; half experienced recurrence (median follow-up 6.7 years). Gene expression alterations were validated...... by qRT-PCR, and functional studies evaluating the effect of siRNA-mediated gene knockdown on cell growth were performed. Twenty-six genes, including TFF3, DACH1, RGS5, and GHR, were shown to exhibit altered expression in tumors from patients with recurrence versus non-recurrent (fold change ≥1.5, p

    Purpose: To report dosimetry and early toxicity data in breast cancer patients treated with postoperative proton radiation therapy. Methods and Materials: From March 2013 to April 2014, 30 patients with nonmetastatic breast cancer and no history of prior radiation were treated with proton therapy at a single proton center. Patient characteristics and dosimetry were obtained through chart review. Patients were seen weekly while on treatment, at 1 month after radiation therapy completion, and at 3- to 6-month intervals thereafter. Toxicity was scored using Common Terminology Criteria for Adverse Events version 4.0. Frequencies of toxicities were tabulated. Results: Median dose delivered was 50.4 Gy (relative biological equivalent [RBE]) in 5 weeks. Target volumes included the breast/chest wall and regional lymph nodes including the internal mammary lymph nodes (in 93%). No patients required a treatment break. Among patients with >3 months of follow-up (n=28), grade 2 dermatitis occurred in 20 patients (71.4%), with 8 (28.6%) experiencing moist desquamation. Grade 2 esophagitis occurred in 8 patients (28.6%). Grade 3 reconstructive complications occurred in 1 patient. The median planning target volume V95 was 96.43% (range, 79.39%-99.60%). The median mean heart dose was 0.88 Gy (RBE) [range, 0.01-3.20 Gy (RBE)] for all patients, and 1.00 Gy (RBE) among patients with left-sided tumors. The median V20 of the ipsilateral lung was 16.50% (range, 6.1%-30.3%). The median contralateral lung V5 was 0.34% (range, 0%-5.30%). The median maximal point dose to the esophagus was 45.65 Gy (RBE) [range, 0-65.4 Gy (RBE)]. The median contralateral breast mean dose was 0.29 Gy (RBE) [range, 0.03-3.50 Gy (RBE)]. Conclusions: Postoperative proton therapy is well tolerated, with acceptable rates of skin toxicity. Proton therapy favorably spares normal tissue without compromising target coverage. Further follow-up is necessary to assess for clinical outcomes and cardiopulmonary

    Purpose: As the recommended radiation dose for non-small-cell lung cancer (NSCLC) increases, meeting dose constraints for critical structures like the brachial plexus becomes increasingly challenging, particularly for tumors in the superior sulcus. In this retrospective analysis, we compared dose-volume histogram information with the incidence of plexopathy to establish the maximum dose tolerated by the brachial plexus. Methods and Materials: We identified 90 patients with NSCLC treated with definitive chemoradiation from March 2007 through September 2010, who had received >55 Gy to the brachial plexus. We used a multiatlas segmentation method combined with deformable image registration to delineate the brachial plexus on the original planning CT scans and scored plexopathy according to Common Terminology Criteria for Adverse Events version 4.03. Results: Median radiation dose to the brachial plexus was 70 Gy (range, 56-87.5 Gy; 1.5-2.5 Gy/fraction). At a median follow-up time of 14.0 months, 14 patients (16%) had brachial plexopathy (8 patients [9%] had Grade 1, and 6 patients [7%] had Grade {>=}2); median time to symptom onset was 6.5 months (range, 1.4-37.4 months). On multivariate analysis, receipt of a median brachial plexus dose of >69 Gy (odds ratio [OR] 10.091; 95% confidence interval [CI], 1.512-67.331; p = 0.005), a maximum dose of >75 Gy to 2 cm{sup 3} of the brachial plexus (OR, 4.909; 95% CI, 0.966-24.952; p = 0.038), and the presence of plexopathy before irradiation (OR, 4.722; 95% CI, 1.267-17.606; p = 0.021) were independent predictors of brachial plexopathy. Conclusions: For lung cancers near the apical region, brachial plexopathy is a major concern for high-dose radiation therapy. We developed a computer-assisted image segmentation method that allows us to rapidly and consistently contour the brachial plexus and establish the dose limits to minimize the risk of brachial plexopathy. Our results could be used as a guideline in future prospective

    Purpose: Constitutively activated signal transducers and activators of transcription (STAT) factors, in particular STAT1, STAT3, and STAT5, have been detected in a wide variety of human primary tumors and have been demonstrated to directly contribute to oncogenesis. However, the expression pattern of these STATs in cervical carcinoma is still unknown, as is whether or not they have prognostic significance. This study investigated the expression patterns of STAT1, STAT3, and STAT5 in cervical cancer and their associations with clinical outcomes in patients treated with radical radiation therapy. Methods and Materials: A total of 165 consecutive patients with International Federation of Gynecology and Obstetrics (FIGO) Stages IB to IVA cervical cancer underwent radical radiation therapy, including external beam and/or high-dose-rate brachytherapy between 1989 and 2002. Immunohistochemical studies of their formalin-fixed, paraffin-embedded tissues were performed. Univariate and multivariate analyses were performed to identify and to evaluate the effects of these factors affecting patient survival. Results: Constitutive activations of STAT1, STAT3, and STAT5 were observed in 11%, 22%, and 61% of the participants, respectively. While STAT5 activation was associated with significantly better metastasis-free survival (p < 0.01) and overall survival (p = 0.04), STAT1 and STAT3 activation were not. Multivariate analyses showed that STAT5 activation, bulky tumor ({>=}4 cm), advanced stage (FIGO Stages III and IV), and brachytherapy (yes vs. no) were independent prognostic factors for cause-specific overall survival. None of the STATs was associated with local relapse. STAT5 activation (odds ratio = 0.29, 95% confidence interval = 0.13-0.63) and advanced stage (odds ratio = 2.54; 95% confidence interval = 1.03-6.26) were independent predictors of distant metastasis. Conclusions: This is the first report to provide the overall expression patterns and prognostic significance of

    Full Text Available This study assesses the morbidity and complications of treatment among long-term survivors of cervical cancer. Ninety-eight female patients who were diagnosed and treated from invasive carcinoma of the cervix uteri 5 years or more are included in this study. All the cases were free of disease and had survived up to December 2010. Forty-one cases were treated with radical hysterectomy with removal of the lymph nodes (Wertheim’s surgery (42%. Radical radiation therapy was given to 57 cases (58% according to our treatment protocol; weekly cisplatin was given concomitantly with radiation. Although urinary adverse effects were more prevalent among the radiation group, the difference was not statistically significant. Bowel dysfunction was more prevalent and statistically significant (p\\0.001 among the radiotherapy arm. Dysfunctions recorded included change in bowel habit, diarrhea, constipation, tenesmus, soiling of clothes and or flatulence. However, their severity was grade 1–2 only. The frequency of small intestinal obstruction was comparable in both arms. Pelvic vein thromboses had a tendency to occur among the surgical group especially in obese females (p value 0.005. The frequency of sexual dysfunction was comparable in both groups with no statistical difference. It was age related. The younger the patients’ ages, the more was the sexual complaint irrespective to the treatment modality. Sexual problems included dyspareunia from vaginal stenosis shortening or dryness, vulval soreness from itching and dryness. Bearing in mind that many patients had more than one health complaint. The remaining cases denied the presence of any complications and stated that they had a normal life style.

    Near infrared (NIR) photoimmunotherapy (PIT) is a new type of molecularly-targeted cancer photo-therapy based on conjugating a near infrared silica-phthalocyanine dye, IR700, to a monoclonal antibody (MAb) targeting cancer-specific cell-surface molecules. When exposed to NIR light, the conjugate induces a highly-selective necrotic/ immunogenic cell death (ICD) only in receptor-positive, MAb-IR700-bound cancer cells. This cell death occurs as early as 1 minute after exposure to NIR light. Meanwhile, immediately adjacent receptor-negative cells including immune cells are unharmed. Therefore, we hypothesized that NIR-PIT could efficiently elicit host immunity against treated cancer cells. Three-dimensional dynamic quantitative phase contrast microscopy and selective plane illumination microscopy of tumor cells undergoing PIT showed rapid swelling in treated cells immediately after light exposure suggesting rapid water influx into cells, followed by irreversible morphologic changes such as bleb formation, and rupture of vesicles. Furthermore, biological markers of ICD including relocation of HSP70/90 and calreticulin, and release of ATP and High Mobility Group Box 1 (HMGB1), were clearly detected immediately after NIR-PIT. When NIR-PIT was performed in a mixture of cancer cells and immature dendritic cells, maturation of immature dendritic cells was strongly induced rapidly after NIR-PIT. In summary, NIR-PIT can induce necrotic/ immunogenic cell death that promotes rapid maturation of immature dendritic cells adjacent to dying cancer cells. Therefore, NIR-PIT could efficiently initiate host immune response against NIR-PIT treated cancer cells growing in patients.

    Full Text Available Despite advances in treatment for metastatic prostate cancer, patients eventually progress to castrate-resistant disease and ultimately succumb to their cancer. Androgen deprivation therapy (ADT is the standard treatment for metastatic prostate cancer and has been shown to improve median time to progression and median survival time. Research suggests that castrate-resistant clones may be present early in the disease process prior to the initiation of ADT. These clones are not susceptible to ADT and may even flourish when androgen-responsive clones are depleted. Stereotactic body radiation therapy (SBRT is a safe and efficacious method of treating clinically localized prostate cancer and metastases. In patients with a limited number of metastatic sites, SBRT may have a role in eliminating castrate-resistant clones and possibly delaying progression to castrate-resistant disease.

    Umbelliprenin (Umb), a natural coumarin, has demonstrated anti-tumor activities, both in vitro and particularly in vivo, in several types of cancer, including lung cancer. The present study aimed to identify molecular targets of Umb using a high-throughput approach. Lung cancer cell lines, QU-DB (large-cell lung carcinoma) and A549 (adenocarcinoma), were treated with Umb. Differentially-expressed proteins were identified using two-dimensional electrophoresis coupled to mass spectrometry. In the QU-DB cells, differential expression of proteins, including downregulation of the tumorigenic protein heat shock protein 90 kDa and upregulation of the potential anti-tumor proteins Nipsnap1 and glycine-tRNA ligase (GRS), suggested that Umb is a strong anti-tumor compound. In the A549 cells, differential expression of proteins indicated possible contradictory effects of Umbregarding tumorigenesis, which included downregulation of the tumorigenic protein cyclophilin and the tumor suppressor MST, and upregulation of stathmin (tumorigenic) and calreticulin. Calreticulun, in addition to GRS in QU-DB cells, stimulates anti-tumor immune responses in vivo. To the best of our knowledge, the present study is the first to use a high-throughput approach to identify targets of Umb in cancer. These molecular targets suggested that Umb may exhibit stronger in vitro anti-tumor activity against the large-cell carcinoma model than the adenocarcinoma model. Furthermore, it has been reported that Umb exhibits higher cytotoxicity against QU-DB cells than A549 cells in vitro, and significant Umb anti-tumor activity against lung cancer in vivo, which is consistent with previously published literature. In each cell type, immune-associated molecules were upregulated, indicating that this naturally occurring compound exhibits marked anti-tumor activity in vivo. However, further studies that investigate the effect of Umb in different in vitro models of cancer are required. PMID:28105238

    To compare the alterations in proteomes between cisplatin-treated and -untreated human ovarian cancer SKOV3 cells, and to explore the feasibility of proteomics in research about antitumor mechanisms of agents, SKOV3 cells were exposed to cisplatin (6 μg/mL) for 6 h. Then, the cells were collected and solubilized and global proteins were extracted by lysis buffer; two-dimensional electrophoresis was conducted with the IPG readystrips as carriers; the gels were stained with Coomassie blue and alterations between gels were compared by PDQuest. Eventually, 11 spots with significant differences were selected and excised and the proteins were identified by PMF and MS/MS analysis. The results revealed that exposure to cisplatin could notably increase expressions of some proteins, such as tropomyosin family, actin family, triosephosphate isomerase family, and HSP60, etc.; while expressions of some other proteins decreased, such as enolase family, etc. Those proteins were involved in cellular energy metabolism, transformation, apoptosis and morphologic maintenance, which suggested that alterations of those physiological processes might be involved in anti-tumor mechanism of cisplatin.

    HPV-infection, p16 positivity, and EGFR expression have been correlated with favorable responses of head and neck cancer patients treated with radiotherapy (RT) with or without chemotherapy. However, a possible correlation of HPV/p16 and EGFR status on the effect of RT in combination with cetuximab has not been sufficiently investigated. We analyzed tumor samples for p16 and EGFR expression and correlated these variables with treatment outcome. Cox-proportional-hazard regression models were applied to compare the risk of death among patients stratified according to risk factors. Survival was estimated by the Kaplan-Meier method. Results were compared with an institutional historical control group treated without cetuximab and with published data. Expression of p16 was predominantly found in oropharyngeal squamous cell cancer patients (OPSCC; 36.6 % positivity; 92 % of all cases), while EGFR was expressed at high levels in all tumor subsites (82 %). p16 expression was associated with improved overall survival in irradiated OPSCC patients (2-year overall survival of 80 % in p16-positive vs. 33 % overall survival in p16-negative patients). In a multivariable analysis covering all tumor sites, nodal stage (> N2a vs. ≤ N2a) and tumor site (OPSSC vs. non-OPSCC) had an impact on overall survival. Our results show that p16 positivity is associated with a favorable outcome in OPSCC patients treated with RT and cetuximab. (orig.)

    Full Text Available Abstract Background A study was performed comparing volumetric modulated arcs (RA and intensity modulation (with photons, IMRT, or protons, IMPT radiation therapy (RT for patients with recurrent prostate cancer after RT. Methods Plans for RA, IMRT and IMPT were optimized for 7 patients. Prescribed dose was 56 Gy in 14 fractions. The recurrent gross tumor volume (GTV was defined on 18F-fluorocholine PET/CT scans. Plans aimed to cover at least 95% of the planning target volume with a dose > 50.4 Gy. A maximum dose (DMax of 61.6 Gy was allowed to 5% of the GTV. For the urethra, DMax was constrained to 37 Gy. Rectal DMedian was 90 parameters. Results Tumor coverage (GTV and PTV was improved with RA (V95% 92.6 ± 7.9 and 83.7 ± 3.3%, when compared to IMRT (V95% 88.6 ± 10.8 and 77.2 ± 2.2%. The corresponding values for IMPT were intermediate for the GTV (V95% 88.9 ± 10.5% and better for the PTV (V95%85.6 ± 5.0%. The percentages of rectal and urethral volumes receiving intermediate doses (35 Gy were significantly decreased with RA (5.1 ± 3.0 and 38.0 ± 25.3% and IMPT (3.9 ± 2.7 and 25.1 ± 21.1%, when compared to IMRT (9.8 ± 5.3 and 60.7 ± 41.7%. CI90 was 1.3 ± 0.1 for photons and 1.6 ± 0.2 for protons. Integral Dose was 1.1 ± 0.5 Gy*cm3 *105 for IMPT and about a factor three higher for all photon's techniques. Conclusion RA and IMPT showed improvements in conformal avoidance relative to fixed beam IMRT for 7 patients with recurrent prostate cancer. IMPT showed further sparing of organs at risk.

    Full Text Available Purpose: To develop a nomogram predictive of current bone scan positivity in patients receiving androgen-deprivation therapy (ADT for advanced prostate cancer; to augment clinical judgment and highlight patients in need of additional imaging investigations.Materials and Methods: A retrospective chart review of bone scan records (conventional 99mTc-scintigraphy of 1,293 patients who received ADT at the Memorial Sloan-Kettering Cancer Center from 2000 to 2011. Multivariable logistic regression analysis was used to identify variables suitable for inclusion in the nomogram. The probability of current bone scan positivity was determined using these variables and the predictive accuracy of the nomogram was quantified by concordance index.Results: In total, 2,681 bone scan records were analyzed and 636 patients had a positive result. Overall, the median pre-scan prostate-specific antigen (PSA level was 2.4 ng/ml; median PSA doubling time (PSADT was 5.8 months. At the time of a positive scan, median PSA level was 8.2 ng/ml; 53% of patients had PSA <10 ng/ml; median PSADT was 4.0 months. Five variables were included in the nomogram: number of previous negative bone scans after initiating ADT, PSA level, Gleason grade sum, and history of radical prostatectomy and radiotherapy. A concordance index value of 0.721 was calculated for the nomogram. This was a retrospective study based on limited data in patients treated in a large cancer centre who underwent conventional 99mTc bone scans, which themselves have inherent limitations. Conclusions: This is the first nomogram to predict current bone scan positivity in ADT-treated prostate cancer patients, providing high predictive accuracy.

    A man in his 60s was admitted for the treatment of advanced cervical esophageal cancer with metastasis to the lymph nodes and advanced tongue cancer with metastasis to the lymph nodes. Esophageal cancer was suspected to have invaded the trachea. The tongue cancer was located on the left side and had invaded beyond the median line of the tongue. Both cancers were pathologically diagnosed as squamous cell carcinomas. Therefore, it was determined that pharyngo-laryngo- esophagectomy and total glossectomy were required prior to the treatment. However, after 2 courses of docetaxel/cisplatin/ 5-FU combined induction chemotherapy, both cancers remarkably decreased; consequently, an esophagectomy to preserve laryngeal function and partial glossectomy could be performed simultaneously. The patient is well without recurrence 1 year post-surgery.

    Cancer is a worldwide public health problem, its prevention and control are included within 16 strategic objectives of the Brazilian Ministry of Health for the period 2011-2015. Cervical cancer is the fourth most common tumor in the female population, being new 15,590 cases estimated for 2014 according to the Brazilian National Cancer Institute (INCA). Pernambuco is the fifth state with the highest number of cases of cervical cancer and the seventh in cases of endometrial ones, both estimative for 2014. The understanding of the epidemiological profile of these pathologies corroborates strategies for prevention, control and treatment. As Pernambuco has implemented the radiotherapy for cancer treatment since 1998-1999, this work encompassed the comparison of the 1998-1999 epidemiological profile of patients treated by radiotherapy for cervical and endometrial cancer in the State of Pernambuco, Brazil, with 2008-2009 profile - ten years after. Medical record of 490 patients treated at the Center of Radiotherapy of Pernambuco (CERAPE) were compiled according to the patient origin, the affected uterus region, the staging of disease, the type and cell differentiation of the tumor, the age group, and, finally, the realization of hysterectomy as part of the treatment. More than 90% of the patients were affected by cervical cancer in the two investigated periods. For the interval of 1998-1999 the proportion of patients submitted to hysterectomy was quite higher compared to those after ten years. The results also showed a change in the origin of the patients, in which, in 1999, most of the patients were from the capital and the metropolitan area, while, after ten years, patients were mostly from the interior of the State. There was a predominance of squamous cell type tumors in both periods evaluated. For the 1998-1999 interval, tumors were stage 2, moderately differentiated type. Differently, the tumors were mostly stage 3, not differentiated type, for the 2008-2009 period

    Full Text Available Abstract Background Prognostic factors in locally advanced breast cancer treated with neoadjuvant chemotherapy differ from those of early breast cancer. The purpose of this study was to identify the clinical significance of potential predictive and prognostic factors in breast cancer patients treated by neoadjuvant chemotherapy. Methods A total of 145 stage II and III breast cancer patients received neoadjuvant docetaxel/doxorubicin chemotherapy were enrolled in this study. We examined the clinical and biological factors (ER, PR, p53, c-erbB2, bcl-2, and Ki-67 by immunohistochemistry. We analyzed clinical outcome and their correlation with clinicopathologic parameters. Results Among the clinicopathologic parameters investigated, none of the marker was correlated with response rate (RR except triple negative phenotype. Patients with triple negative phenotype showed higher RR (83.0% in triple negative vs. 62.2% in non-triple negative, p = 0.012 and pathologic complete RR (17.0% in triple negative vs. 3.1% in non-triple negative, p = 0.005. However, relapse free survival (RFS and overall survival (OS were significantly shorter in triple negative breast cancer patients (p p = 0.021, respectively. Low histologic grade, positive hormone receptors, positive bcl-2 and low level of Ki-67 were associated with prolonged RFS. In addition, positive ER and positive bcl-2 were associated with prolonged OS. In our homogeneous patient population, initial clinical stage reflects RFS and OS more precisely than pathologic stage. In multivariate analysis, initial clinical stage was the only significant independent prognostic factor to impact on OS (hazard ratio 3.597, p = 0.044. Conclusion Several molecular markers provided useful predictive and prognostic information in stage II and III breast cancer patients treated with neoadjuvant docetaxel/doxorubicin chemotherapy. Triple negative phenotype was associated with shorter survival, even though it was associated

    Purpose: We previously evaluated the risk of breast cancer-related lymphedema (LE) with the addition of regional lymph node irradiation (RLNR) and found an increased risk when RLNR is used. Here we analyze the association of technical radiation therapy (RT) factors in RLNR patients with the risk of LE development. Methods and Materials: From 2005 to 2012, we prospectively screened 1476 women for LE who underwent surgery for breast cancer. Among 1507 breasts treated, 172 received RLNR and had complete technical data for analysis. RLNR was delivered as supraclavicular (SC) irradiation (69% [118 of 172 patients]) or SC plus posterior axillary boost (PAB) (31% [54 of 172]). Bilateral arm volume measurements were performed pre- and postoperatively. Patients' RT plans were analyzed for SC field lateral border (relative to the humeral head), total dose to SC, RT fraction size, beam energy, and type of tangent (normal vs wide). Cox proportional hazards models were used to analyze associated risk factors for LE. Results: Median postoperative follow-up was 29.3 months (range: 4.9-74.1 months). The 2-year cumulative incidence of LE was 22% (95% confidence interval [CI]: 15%-32%) for SC and 20% (95% CI: 11%-37%) for SC plus PAB (SC+PAB). None of the analyzed variables was significantly associated with LE risk (extent of humeral head: P=.74 for <1/3 vs >2/3, P=.41 for 1/3 to 2/3 vs >2/3; P=.40 for fraction size of 1.8 Gy vs 2.0 Gy; P=.57 for beam energy 6 MV vs 10 MV; P=.74 for tangent type wide vs regular; P=.66 for SC vs SC+PAB). Only pretreatment body mass index (hazard ratio [HR]: 1.09; 95% CI: 1.04-1.15, P=.0007) and the use of axillary lymph node dissection (HR: 7.08, 95% CI: 0.98-51.40, P=.05) were associated with risk of subsequent LE development. Conclusions: Of the RT parameters tested, none was associated with an increased risk of LE development. This study underscores the need for future work investigating alternative RLNR risk factors for LE.

    Purpose: The benefit of adding androgen deprivation therapy (ADT) to dose-escalated radiation therapy (RT) for men with intermediate-risk prostate cancer is unclear; therefore, we assessed the impact of adding ADT to dose-escalated RT on freedom from failure (FFF). Methods: Three groups of men treated with intensity modulated RT or 3-dimensional conformal RT (75.6-78 Gy) from 1993-2008 for prostate cancer were categorized as (1) 326 intermediate-risk patients treated with RT alone, (2) 218 intermediate-risk patients treated with RT and ≤6 months of ADT, and (3) 274 low-risk patients treated with definitive RT. Median follow-up was 58 months. Recursive partitioning analysis based on FFF using Gleason score (GS), T stage, and pretreatment PSA concentration was applied to the intermediate-risk patients treated with RT alone. The Kaplan-Meier method was used to estimate 5-year FFF. Results: Based on recursive partitioning analysis, intermediate-risk patients treated with RT alone were divided into 3 prognostic groups: (1) 188 favorable patients: GS 6, ≤T2b or GS 3+4, ≤T1c; (2) 71 marginal patients: GS 3+4, T2a-b; and (3) 68 unfavorable patients: GS 4+3 or T2c disease. Hazard ratios (HR) for recurrence in each group were 1.0, 2.1, and 4.6, respectively. When intermediate-risk patients treated with RT alone were compared to intermediate-risk patients treated with RT and ADT, the greatest benefit from ADT was seen for the unfavorable intermediate-risk patients (FFF, 74% vs 94%, respectively; P=.005). Favorable intermediate-risk patients had no significant benefit from the addition of ADT to RT (FFF, 94% vs 95%, respectively; P=.85), and FFF for favorable intermediate-risk patients treated with RT alone approached that of low-risk patients treated with RT alone (98%). Conclusions: Patients with favorable intermediate-risk prostate cancer did not benefit from the addition of ADT to dose-escalated RT, and their FFF was nearly as good as patients with low-risk disease

    Infections related to anti-HER2 monoclonal antibodies (mAbs), trastuzumab and pertuzumab, have been reported in clinical trials. It is not yet clear whether these drugs increase an infection risk or not. We performed a systematic review and meta-analysis to assess the risk of infections associated with anti-HER2 mAbs. We searched PubMed and the ASCO online database of meeting abstracts up to January 2014 for relevant clinical trials. Eligible studies included randomized controlled trials of trastuzumab or pertuzumab for breast cancer patients that reported adequate safety data for grade 3-4 infection, febrile neutropenia, neutropenia, or leukopenia. The summary incidence, relative risk (RR), and 95 % confidence intervals (CIs) were calculated. A total of 10,094 patients from 13 trials were included. The use of trastuzumab was associated with an increased risk of high-grade infection (RR 1.21, 95 % CI 1.07-1.37, P = 0.002) and febrile neutropenia (RR 1.28, 95 % CI 1.08-1.52, P = 0.004). The incidence of high-grade infection and febrile neutropenia due to trastuzumab was 8.5 % (95 % CI 4.5-15.4 %) and 12.0 % (95 % CI 8.1-17.4 %), respectively. There was no significant increase in a risk of high-grade neutropenia or leukopenia in patients receiving trastuzumab. Treatment with trastuzumab is associated with a significantly higher risk of high-grade infection and febrile neutropenia. Our findings suggest an importance of close monitoring for any signs of infections in patients treated with trastuzumab.

    Background: Radiation-induced DNA damage in human lymphocytes has equal probability of producing both stable or unstable chromosome aberrations (C.A.). Reports of its in vivo persistence show considerable variations. The quantification of unstable C.A. (dicentrics) in peripheral blood lymphocytes (P.B.L.) is the most reliable biological method for estimating whole-body doses of recent overexposures to ionizing radiation. Given that during the division of T cell precursors, proliferative death of cells containing dicentrics reduces the number of such lymphocytes in peripheral blood, dicentric methodology should be modified to account for past exposures. Micronuclei (M.N.) in cytokinesis-blocked human P.B.L. are well established bio markers for assessing radiation damage in vivo. However, persistence of radiation induced M.N. is limited. Unlike dicentrics and M.N., stable C.A. (translocations) identified at present by the FISH technique, seem to be an adequate indicator for the dosimetric evaluation of past exposures, since translocations are not selected against during mitotic division in the haematopoietic stem cells compartment. Nevertheless, for partial -body exposures with high dose there is some evidence that the decline with time of dicentrics causes some reduction in the yield of translocations. Purpose: To assess the persistence along time of dicentrics, M.N. and translocations in lymphocytes of cancer patients after radiotherapy in order to model changes in C.A. frequencies with partial-body exposures. Materials and methods: 22 cancer patients with different tumor sites, treated with radiotherapy, were evaluated through dicentric chromosome, M.N. and FISH techniques with a follow-up time of up to 90 months after the end of radiotherapy. Regression analysis were performed: 1) for dicentric and for M.N. frequencies in relation to time after the end of radiotherapy and total tumor dose; 2) for the percentage of uns table cells in relation to time after the end

    For many years, crude coal tar has been used for the treatment of psoriasis. The possible carcinogenic effect of crude coal tar and ultraviolet (UV) radiation (Goeckerman regimen), considered individually or in combination, has been of some concern to physicians. A 25-year follow-up study was completed on 280 patients with psoriasis who were hospitalized and treated with crude coal tar and UV radiation at the Mayo Clinic, Rochester, Minn, during the years 1950 through 1954. The results of this study suggest that the incidence of skin cancer is not appreciably increased above the expected incidence for the general population when patients are treated with coal tar ointments. It seems that the Goeckerman regimen (topical crude coal tar combined with UV radiation) can be used with minimal risk for skin cancer in the treatment of psoriasis.

    Full Text Available Non-small cell lung cancer (NSCLC accounts for the majority of all lung cancers. A 69-year-old female with postoperatively recurrent NSCLC was treated weekly with nanoparticle-albumin-bound paclitaxel (nab-paclitaxel monotherapy every 4 weeks as a tenth line chemotherapy, and stable disease was achieved by seven cycles of this regimen. The patient developed grade 4 neutropenia and grade 3 leukopenia, but none of the other toxicities, including febrile neutropenia and peripheral neuropathy, were severe, and thus she was able to tolerate this salvage chemotherapy. To our knowledge this is the first report of the efficacy of nab-paclitaxel monotherapy in a heavily treated NSCLC patient.

  16. Transcriptome analysis of Wnt3a-treated triple-negative breast cancer cells.

    Directory of Open Access Journals (Sweden)

    Sylvie Maubant

    Full Text Available The canonical Wnt/β-catenin pathway is activated in triple-negative breast cancer (TNBC. The activation of this pathway leads to the expression of specific target genes depending on the cell/tissue context. Here, we analyzed the transcriptome of two different TNBC cell lines to define a comprehensive list of Wnt target genes. The treatment of cells with Wnt3a for 6h up-regulated the expression (fold change > 1.3 of 59 genes in MDA-MB-468 cells and 241 genes in HCC38 cells. Thirty genes were common to both cell lines. Beta-catenin may also be a transcriptional repressor and we found that 18 and 166 genes were down-regulated in response to Wnt3a treatment for 6h in MDA-MB-468 and HCC38 cells, respectively, of which six were common to both cell lines. Only half of the activated and the repressed transcripts have been previously described as Wnt target genes. Therefore, our study reveals 137 novel genes that may be positively regulated by Wnt3a and 104 novel genes that may be negatively regulated by Wnt3a. These genes are involved in the Wnt pathway itself, and also in TGFβ, p53 and Hedgehog pathways. Thorough characterization of these novel potential Wnt target genes may reveal new regulators of the canonical Wnt pathway. The comparison of our list of Wnt target genes with those published in other cellular contexts confirms the notion that Wnt target genes are tissue-, cell line- and treatment-specific. Genes up-regulated in Wnt3a-stimulated cell lines were more strongly expressed in TNBC than in luminal A breast cancer samples. These genes were also overexpressed, but to a much lesser extent, in HER2+ and luminal B tumors. We identified 72 Wnt target genes higher expressed in TNBCs (17 with a fold change >1.3 which may reflect the chronic activation of the canonical Wnt pathway that occurs in TNBC tumors.

    Sirtuins comprise a family of deacetylase enzymes that catalyze the removal of an acetyl moiety from the ɛ-amino group of lysine residues within protein targets. Sirtuin 1(SIRT1), a NAD(+) dependent class III histone deacetylase is involved in a variety of human disorders such as obesity, type II diabetes, cancer and aging. Inhibition of SIRT1 could be useful for cancer treatment while activators can be useful for longevity and treating metabolic disorders. Hence we undertook an effort to design both inhibitors and activators using structure-based drug design techniques and report here the biological proof of concept. In this paper, we report diverse small molecule inhibitors with a potential to attenuate cancer growth designed based on high-throughput virtual screening and docking using the crystal structure of SIRT1. And small molecule activators with potential to suppress adipogenesis differentiation indicating their usefulness in obesity control was designed based on a homology model of SIRT1 activator domain.

    Human vaccines against infectious agents are often effective in a prophylactic setting. However, they are usually not effective when used post-exposure. Rabies vaccine is one of the exceptions, which can be used post-exposure, but is effective only when used in combination with other treatments. Similar results have been obtained with cancer vaccines and immunotherapies. Cancer immunotherapies generally prolong patients' survival when they are used during advanced stage disease. The potential of immunotherapy to cure cancer could be revealed when it is applied in a prophylactic setting. This article provides a brief overview of cancer immunotherapeutics and suggests that immunotherapy can cure cancer if used at the right time against the right target; we suggest that targeting cancer during dormancy in order to prevent tumor recurrence as advanced stage disease is potentially curative.

Our study explored background rates of cardiovascular disease (CVD events among HEC- or MEC-treated cancer patients in a population-based setting to contextualize events seen in a new drug development program and to determine at a high level whether rates differed by aprepitant usage. Medical and pharmacy claims data from the 2005–2007 IMPACT National Benchmark Database were classified into emetogenic chemotherapy categories and CVD outcomes. Among 5827 HEC/MEC-treated patients, frequencies were highest for hypertension (16–21% and composites of venous (7–12% and arterial thromboembolic events (4–7%. Aprepitant users generally did not experience higher frequencies of events compared to nonusers. Our study serves as a useful benchmark of background CVD event rates in a population-based setting of cancer patients.

    Chlorophyllin (CHL) is a water-soluble derivative of chlorophyll that exhibits cancer chemopreventive properties, but which also has been studied for its possible cancer therapeutic effects. We report here that human colon cancer cells treated with CHL accumulate in S-phase of the cell cycle, and this is associated with reduced expression levels of p53, p21, and other G(1)/S checkpoint controls. At the same time, E2F1 and E2F4 transcription factors become elevated and exhibit increased DNA binding activity. In CHL-treated colon cancer cells, bromodeoxyuridine pulse-chase experiments provided evidence for the inhibition of DNA synthesis. Ribonucleotide reductase (RR), a pivotal enzyme for DNA synthesis and repair, was reduced at the mRNA and protein level after CHL treatment, and the enzymatic activity was inhibited in a concentration-dependent manner both in vitro and in vivo. Immunoblotting revealed that expression levels of RR subunits R1, R2, and p53R2 were reduced by CHL treatment in HCT116 (p53(+/+)) and HCT116 (p53(-/-)) cells, supporting a p53-independent mechanism. Prior studies have shown that reduced levels of RR small subunits can increase the sensitivity of colon cancer cells to clinically used DNA-damaging agents and RR inhibitors. We conclude that by inhibiting R1, R2, and p53R2, CHL has the potential to be effective in the clinical setting, when used alone or in combination with currently available cancer therapeutic agents.

    Purpose: To investigate the prognostic utility of the percentage of cancer volume (PCV) in needle biopsy specimens for prostate cancer patients treated with dose-escalated external beam radiotherapy. Methods and Materials: The outcomes were analyzed for 599 men treated for localized prostate cancer with external beam radiotherapy to a minimal planning target volume dose of 75 Gy (range, 75-79.2). We assessed the effect of PCV and the pretreatment and treatment-related factors on the freedom from biochemical failure, freedom from metastasis, cause-specific survival, and overall survival. Results: The median number of biopsy cores was 7 (interquartile range, 6-12), median PCV was 10% (interquartile range, 2.5-25%), and median follow-up was 62 months. The PCV correlated with the National Comprehensive Cancer Network risk group and individual risk features, including T stage, prostate-specific antigen level, Gleason score, and percentage of positive biopsy cores. On log-rank analysis, the PCV stratified by quartile was prognostic for all endpoints, including overall survival. In addition, the PCV was a stronger prognostic factor than the percentage of positive biopsy cores when the two metrics were analyzed together. On multivariate analysis, the PCV predicted a worse outcome for all endpoints, including freedom from biochemical failure, (hazard ratio, 1.9; p = .0035), freedom from metastasis (hazard ratio, 1.7, p = .09), cause-specific survival (hazard ratio, 3.9, p = .014), and overall survival (hazard ratio, 1.8, p = .02). Conclusions: For patients treated with dose-escalated external beam radiotherapy, the volume of cancer in the biopsy specimen adds prognostic value for clinically relevant endpoints, particularly in intermediate- and high-risk patients. Although the PCV determination is more arduous than the percentage of positive biopsy cores, it provides superior risk stratification.

Major questions regarding optimal management of mCRC await resolution.Methods: A thorough review was conducted of all mCRC abstracts, posters, and other presentations at the 2007 meeting of the American Society of Clinical Oncology (ASCO. Information was analyzed in relationship to previously published research to determine the potential impact of new data on current and future mCRC management strategies and patient outcomes. Updated data presented at ASCO 2008 relevant to these findings was also analyzed.Discussion: Ongoing challenges in mCRC treatment include defining the optimal role of targeted agents such as cetuximab and bevacizumab, elaborating the mechanisms underlying their toxicities, resolving the benefits of adjuvant and neoadjuvant chemotherapy in patients who are candidates for surgical resection, establishing whether there are substantive differences between sequential and combination chemotherapy regimens, and determining the safety and tolerability of chemotherapy in elderly subjects.Conclusion: Recent reports presented at ASCO 2007 and 2008 indicate incremental improvements in care of patients with mCRC. Nevertheless, irinotecan, oxaliplatin, 5-FU, and to an increasing extent the targeted biologic agents bevacizumab and cetuximab continue unchallenged as first-line and later selections.Keywords: chemotherapy, combination chemotherapy, irinotecan, bevacizumab, cetuximab

    Over the last 10 years there has been a dramatic increase in the number of patients identified and treated with testosterone replacement therapy (TRT) for late-onset hypogonadism (LOH). By virtue of age, race, and family history, many of these patients are concurrently at risk for harboring indolent prostate cancer. Other men are at increased risk for prostate cancer as a result of an elevated serum PSA level or having had a prior prostate biopsy showing prostatic intraepithelial neoplasia (PIN) or atypical small acinar proliferation (ASAP). The clinician is often challenged with the decision whether to initiate TRT in these patients. This review presents a contemporary overview of the rationale for TRT, as well as the relationship between testosterone (endogenous and exogenous) and premalignant and malignant lesions of the prostate. We will discuss preliminary data from several recent series demonstrating that TRT may be safely administered in select patients with certain premalignant and bona fide malignant tumors of the prostate. In the absence of a large randomized clinical trial with long-term outcome data evaluating TRT, we hope that this overview will provide clinicians with an evidence-based approach to managing these anxiety-provoking - and often frustrating - clinical scenarios.

    Purpose: To investigate the relative importance of patient-reported hip and sacral pain after pelvic radiotherapy (RT) for gynecological cancer and its relationship to the absorbed doses in these organs. Methods and Materials: We used data from a population-based study that included 650 long-term gynecological cancer survivors treated with pelvic RT in the Gothenburg and Stockholm areas in Sweden with a median follow-up of 6 years (range, 2-15) and 344 population controls. Symptoms were assessed through a study-specific postal questionnaire. We also analyzed the hip and sacral dose-volume histogram data for 358 of the survivors. Results: Of the survivors, one in three reported having or having had hip pain after completing RT. Daily pain when walking was four times as common among the survivors compared to controls. Symptoms increased in frequency with a mean absorbed dose >37.5 Gy. Also, two in five survivors reported pain in the sacrum. Sacral pain also affected their walking ability and tended to increase with a mean absorbed dose >42.5 Gy. Conclusions: Long-term survivors of gynecological cancer treated with pelvic RT experience hip and sacral pain when walking. The mean absorbed dose was significantly related to hip pain and was borderline significantly related to sacral pain. Keeping the total mean absorbed hip dose below 37.5 Gy during treatment might lower the occurrence of long-lasting pain. In relation to the controls, the survivors had a lower occurrence of pain and pain-related symptoms from the hips and sacrum compared with what has previously been reported for the pubic bone.

    Objective: In comparison with chemotherapy, to evaluate therapeutic effcts on advanced pancreatic cancer treated by integrative Chinese and western medicine (ICWM) therapies. Methods: Based on the retrospective study of 56 patients with advanced pancreatic cancer,life table was applied to the analysis of patients' survival rate and χ2 test to the comparison of therapeutic response between ICWM and chemotherapy groups. Results: The results showed that 1-year survival rate in the ICWM group was 55.37%±3.24%; 2-year survival rate 34.61%±16.31%; 3-year survival rate 25.96%±24.64%; 5-year survival rate 25.96%±24.64%; and median survival period 16.3 months. However 1-year survival rate in the chemotherapy group was 21.95%±27.54%; 2-year survival rate 7.31%±27.54%; 3-year survival rate 0%; and median survival period 7.5 months. The therapeutic effects between two groups were significantly different (P=0.004). Further analysis suggested that the reduction of cancer mass in the ICWM group was more than that in chemotherapy group (P=0.049) and the improvement of advanced pancreatic cancer related-symptoms better than that of chemotherapy group (P=0.002). Conclusion: The ICWM comprehensive therapy is of important value in the treatment of advanced pancreatic cancer.

    Ovarian cancer is amongst the most common types of cancer in women, with a relatively low overall cure rate of approximately 30%. This is therefore an important incentive to urge for further research in order to maximize the chances of survival for these patients. Intraperitoneal chemotherapy with Cisplatin is an effective treatement for ovarian cancer; however, many questions still remain concerning the ideal treatment protocol and tumor resistance towards the drug, which should be resolved for optimal application of this therapy. For the first time in-vivo grown tumors treated with both hyper- and normothermic intraperitoneal chemotherapy have been studied using nano-XRF spectroscopy to examine the platinum (Pt) distribution within the analyzed tissues. These measurements prove Pt resides predominantly outsides the cancer cells in the stroma of the tissue. These findings indicate the resistance mechanism of the cancer cells prevents Cisplatin from diffusing through their cell membranes. This is an important addition to the existing knowledge on the resistance mechanism providing insights which might help to overcome this effect. In our aim to find the optimal treatment protocol, no significant differences were found between the two examined procedures. A more extensive data set will be needed to draw definite conclusions.

    Breast cancer is one of the most common female malignant tumors. According to data statistics, the incidence of breast cancer was 7% to 10% for a variety of malignant tumors, being only lower than that of uterine cancer. The methods of treating breast cancer are given priority over operative treatment and combined with chemotherapy and radiotherapy. However, exosmosis of chemotherapeutic drugs is a common complication of chemotherapy. Exosmosis of drugs can stimulate local organs to induce acute inflammatory reaction and necrosis, which finally lead to wound infection and difficulty in healing. In December 2013, a patient with full-thickness wound (an area of 5 × 3 cm) dehiscence at the completion of the second phase of chemotherapy for left breast cancer after radical operation was admitted to our department. Her wound had healed after radical operation. The patient followed an integrative therapy treatment protocol that consisted of an external application of a phytomedicine called Sanguis Draconis and combined with a series of conventional treatments, including 3M Transparent Dressing moist therapy, increase in nutrition, and prevention therapies for infection. The patient's integrative treatment program resulted in complete wound healing, and the successful completion of the late 6 courses of chemotherapy. The article describes the nursing experiences associated with this case study.

Patients and methods: QoL was assessed in advanced cancer patients at baseline and after 7 days of symptomatic treatment using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 15-Palliative Care (EORTC QLQ-C15-PAL, the Edmonton Symptom Assessment System (ESAS, and the Karnofsky Performance Status (KPS scale. Results: A total of 129 patients completed the study, with 51 patients treated at home, 51 patients treated at the PCU, and 27 patients at DCC. In the EORTC QLQ-C15-PAL, improvement in functional and symptom scales was observed except in physical functioning and fatigue levels; patients at DCC had a better physical functioning, global QoL, appetite, and fatigue levels. In the ESAS, improvement in all items was found except for drowsiness levels, which was stable in patients treated at DCC and deteriorated in home and PCU patients. Higher activity, better appetite and well-being, and less drowsiness were observed in patients treated at DCC. KPS was better in DCC patients compared to those treated at home and at the PCU; the latter group deteriorated. Conclusions: QoL improved in all patient groups, with better results in DCC patients and similar scores in those staying at home and at the PCU. Along with clinical assessment, baseline age, KPS, physical and emotional functioning may be considered when assigning patients to care at a DCC, PCU, or at home. Keywords: oncology, patient care

    Objective To evaluate the clinical characteristics and outcomes of patients with Gleason score 10 prostate cancer treated by external radiotherapy and hormone therapy. Methods From January 2003 to March 2014, 1832 patients with prostate cancer were treated, among which 9 patients (represented 0.49%) were identified as Gleason score 10 disease on prostate core biopsy without distant metastases when first diagnosed. All 9 patients were treated by whole pelvic external radiotherapy (The whole pelvic dose was 50.0 Gy and the boost dose ranged from 76.2 to 78.0 Gy) and long-term hormone therapy. We assessed the clinical characteristics, treatment outcomes and treatment toxicities. Survival curves were calculated using the Kaplan-Meier method. Results The median follow-up was 4.8 years. Six patients’ pre-treatment prostate-specific antigen (PSA) levels were lower than 20.0μg/L and three patients’ pre-treatment PSA levels were higher than 70.0μg/L. The median percentage of positive biopsy cores was 91%. Three, four and two cases were classified as T2c, T3a and T3b stage, respectively. Three cases were assessed as N1 stage. The 5-year biochemical failure-free survival, distant metastasis-free survival, cancer specific survival and overall survival rates were 28.6%, 57.1%, 66.7%and 57.1%, respectively. Five patients experienced grade 1-2 acute gastrointestinal toxicities and six patients complained of grade 1-2 acute genitourinary toxicities. No bone fracture or cardiovascular disease was detected. Conclusions Gleason score 10 prostate cancer on core biopsy is usually combined with other high risk factors. The pre-treatment PSA levels lie in two extremes. Timely and active treatments are urgent needed because unfavourable oncological outcomes are often presented.

    Aromatase inhibitors (AI), either alone or together with chemotherapy, have become the standard adjuvant treatment for postmenopausal, estrogen receptor-positive (ER+) breast cancer. Although AIs improve overall survival, resistance is still a major clinical problem, thus additional biomarkers predictive of outcome of ER+ breast cancer patients treated with AIs are needed. Global gene expression analysis was performed on ER+ primary breast cancers from patients treated with adjuvant AI monotherapy; half experienced recurrence (median follow-up 6.7 years). Gene expression alterations were validated by qRT-PCR, and functional studies evaluating the effect of siRNA-mediated gene knockdown on cell growth were performed. Twenty-six genes, including TFF3, DACH1, RGS5, and GHR, were shown to exhibit altered expression in tumors from patients with recurrence versus non-recurrent (fold change ≥1.5, p proliferation, growth, and development. TFF3, which encodes for trefoil factor 3 and is an estrogen-responsive oncogene shown to play a functional role in tamoxifen resistance and metastasis of ER+ breast cancer, was also shown to be upregulated in an AI-resistant cell line model, and reduction of TFF3 levels using TFF3-specific siRNAs decreased the growth of both the AI-resistant and -sensitive parental cell lines. Moreover, overexpression of TFF3 in parental AI-sensitive MCF-7/S0.5 cells resulted in reduced sensitivity to the AI exemestane, whereas TFF3 overexpression had no effect on growth in the absence of exemestane, indicating that TFF3 mediates growth and survival signals that abrogate the growth inhibitory effect of exemestane. We identified a panel of 26 genes exhibiting altered expression associated with disease recurrence in patients treated with adjuvant AI monotherapy, including TFF3, which was shown to exhibit a growth- and survival-promoting effect in the context of AI treatment.

    Recent literature on chemoradiotherapy for esophageal cancer report the comparable survival results as surgery, and suggest the importance of management for the late adverse effect of chemoradiotherapy. The aim of this study is to investigate the incidence and risk factors of cardiomegaly after chemoradiotherapy using low dose continuous infusion of 5FU/CDDP+5FU for esophageal cancer. Fifty-one patients with stage I-IVA esophageal cancer who were treated by radiotherapy with more than 50 Gy with or without chemotherapy and followed up for more than 6 months were analyzed. Sixteen patients were treated by radiation alone and 35 patients were treated by chemoradiotherapy. A change of CTR (cardio-thoracic ratio) was defined as the difference between CTR in the pre-treatment X-ray film and CTR in the post-treatment X-ray film with maximum cardiac silhouette. A change of CTR by more than 10% was defined as ''significant cardiomegaly''. In this study cardiac area-dose'', which is the sum of the products of cardiac area within every radiation field and its target dose, was calculated in each patient as a radiation parameter. Significant cardiomegaly was noted in 1 patient (6%) in the radiation alone group, in 8 patients (23%) in the chemoradiotherapy group and in 9 patients (18%) in the total population. In cases with more than 0.4 m{sup 2}{center_dot}Gy in cardiac area-dose, CTR elevation was significantly higher than in cases with less than 0.4m{sup 2}{center_dot}Gy. More than moderate pleural effusion was noted in 5 patients (10%). Chronic pericardial effusion and subsequent cardiac tamponade was considered to be one of the contributing factors for pleural effusion, because increases of pleural effusion coincided with CTR elevations in 3 cases. In addition, the fact that no case had right-sided unilateral pleural effusion suggested the direct effect of radiation to the pleura. Significant cardiomegaly was seen in 18% of 51 patients with

    Purpose: To compare the second malignancy incidence in prostate cancer patients treated with brachytherapy (BT) relative to radical prostatectomy (RP) and to compare both groups with the cancer incidence in the general population. Methods and Materials: From 1998 to 2010, 2418 patients were treated with Iodine 125 prostate BT monotherapy at the British Columbia Cancer Agency, and 4015 referred patients were treated with RP. Cancer incidence was compared with the age-matched general population using standardized incidence ratios (SIRs). Pelvic malignancies included invasive and noninvasive bladder cancer and rectal cancer. Cox multivariable analysis was performed with adjustment for covariates to determine whether treatment (RP vs BT) was associated with second malignancy risk. Results: The median age at BT was 66 years and at RP 62 years. The SIR comparing BT patients with the general population was 1.06 (95% confidence interval [CI] 0.91-1.22) for second malignancy and was 1.53 (95% CI 1.12-2.04) for pelvic malignancy. The SIR comparing RP patients with the general population was 1.11 (95% CI 0.98-1.25) for second malignancy and was 1.11 (95% CI 0.82-1.48) for pelvic malignancy. On multivariable analysis, older age (hazard ratio [HR] 1.05) and smoking (HR 1.65) were associated with increased second malignancy risk (P<.0001). Radical prostatectomy was not associated with a decreased second malignancy risk relative to BT (HR 0.90, P=.43), even when excluding patients who received postprostatectomy external beam radiation therapy (HR 1.13, P=.25). Older age (HR 1.09, P<.0001) and smoking (HR 2.17, P=.0009) were associated with increased pelvic malignancy risk. Radical prostatectomy was not associated with a decreased pelvic malignancy risk compared with BT (HR 0.57, P=.082), even when excluding postprostatectomy external beam radiation therapy patients (HR 0.87, P=.56). Conclusions: After adjustment for covariates, BT patients did not have an increased second

    Purpose: The new 7th edition of the American Joint Committee on Cancer TNM staging system is based on pathologic data from esophageal cancers treated by surgery alone. There is no information available on evaluation of the new staging system with regard to prognosis of patients treated with chemoradiotherapy (CRT). The objective of this study was to evaluate the prognostic impact of the new staging system on esophageal cancer patients treated with CRT. Methods and Materials: A retrospective review was performed on 301 consecutive esophageal squamous cell carcinoma patients treated with CRT. Comparisons were made of the prognostic impacts of the 6th and 7th staging systems and the prognostic impacts of stage and prognostic groups, which were newly defined in the 7th edition. Results: There were significant differences between Stages I and III (p < 0.01) according to both editions. However, the 7th edition poorly distinguishes the prognoses of Stages III and IV (p = 0.36 by multivariate analysis) in comparison to the 6th edition (p = 0.08 by multivariate analysis), although these differences were not significant. For all patients, T, M, and gender were independent prognostic factors by multivariate analysis (p < 0.05). For the Stage I and II prognostic groups, survival curves showed a stepwise decrease with increase in stage, except for Stage IIA. However, there were no significant differences seen between each prognostic stage. Conclusions: Our study indicates there are several problems with the 7th TNM staging system regarding prognostic factors in patients undergoing CRT.

    5-Fluorouracil (5-FU) is the major chemotherapeutic agent for the treatment of colorectal carcinoma, which were found to have N-glycans containing polylactosamine on the cancer cell surface. Alterations in the expression and structure of polylactosamine glycans are associated with cellular differentiation and oncogenesis. However, little is known with regard to the correlation between the levels of polylactosamine expressed in colon cancer cells and the anticancer effect of 5-FU. In the present study, SW620 cells were treated with the half maximal inhibitory concentration (IC50; determined by MTT-assay) of 5-FU. Hoechst 33258 staining and flow cytometric analysis indicated that 5-FU administration resulted in apoptosis in SW620 cells. An increased percentage of cells in S phase was also observed among the SW620 cells treated with 5-FU. Under the same experimental conditions, a decrease in the 5-FU‑induced inhibition of polylactosamine glycans was recorded. However, an increase in the activity of alkaline phosphatase was also observed. Furthermore, pretreatment of the SW620 cells with 5-FU inhibited the expression of β1,3-N-acetylglucosaminyltransferase-8 (β3Gn-T8) and cluster of differentiation (CD)147 in a time-dependent manner. Overall, changes in glycosylation were associated with the anticancer effect of 5-FU in the colon cancer cells. In conclusion, polylactosamine may be a useful target for the identification of substances with anticancer activity.

    It is estimated that for a quarter of all patients with advanced metastatic cancer, depression will be significant symptom. However up to 80% of the psychological and psychiatric morbidity which develops in cancer patients goes unrecognised and untreated. One of the main difficulties in establishing a diagnosis of an illness where there are no biological markers, physical signs, or diagnostics tests is deciding what can be called "appropriate sadness" as patients approach the end of life and ...

    Full Text Available Introduction. Use of complementary and alternative medicine (CAM in cancer patients is increasingly acceptable worldwide, but most of the studies were surveyed from developed countries. In this study, we evaluated the first and large cohort of cancer patients with CAM use in Thailand. Materials and Methods. A self-administered questionnaire was completed by 248 cancer patients attending outpatient radiotherapy unit at Ramathibodi Hospital. Results. The prevalence of CAM use was 60.9%. The most frequently used CAM were dietary/vitamin supplements (56.9%. Independent predictors of CAM use were high income (<0.001 and cancer type (=0.019. About half of the patients (51% reported positive effects from CAM use. Nevertheless, 9.4% of the patient also reported side effects. The majority of patients (58.3% did not disclose their use of CAM to their doctors because they felt that it was not necessary for doctors to know (65.9%. The average spending for CAM use was 200 USD/month (range, 10–1,000. Conclusion. Although the cost for CAM is relatively expensive, the prevalence of CAM use in cancer patients in Thailand is high particularly, in patients with higher income. Therefore, all clinical oncologists should be concerned about the use of CAM during evaluation of the cancer patients.

    Full Text Available The purpose of this case report is to show the potential benefit of Korean medicine therapy for treating multiple metastatic breast cancer. A 45-year-old Korean woman was diagnosed with right breast invasive ductal carcinoma in August 2012 but did not receive any treatment until October 2015 when she was diagnosed with stage 4 right breast cancer with multiple liver, bone, mesentery, retroperitoneum, and axillary lymph node metastases. After chemo-port insertion, she was treated with palliative chemotherapy and the first line of trastuzumab and paclitaxel, and the port was removed due to port infection. To treat sepsis, vancomycin and tazoperan were administered, before the third line of trastuzumab and paclitaxel was carried out. However, the patient gave up chemotherapy due to vancomycin-resistant enterococci and general weakness. Later, she received Korean medicine therapy with wild ginseng pharmacopuncture, distilled Soramdan S, Hae, and Jeobgoldan for 8 months, which led to a significant decrease of the multiple metastases. The patient was able to start walking again with the help of a walking stick. However, a new metastatic lesion was found on the right adrenal gland. This case suggests that the combination of chemotherapy and Korean medicine therapy may be valuable. Further research is indicated.

    Among breast cancer patients, those diagnosed with the triple-negative breast cancer (TNBC) subtype have the worst prog-nosis. TNBC does not express estrogen receptor-alpha, progesterone receptor, or the HER2 oncogene; therefore, TNBC lacks targets for molecularly-guided therapies. The concept that EGFR oncogene inhibitor drugs could be used as targeted treatment against TNBC has been put forth based on estimates that 30–60% of TNBC express high levels of EGFR. However, results from clinical trials testing EGFR inhibitors, alone or in combination with cytotoxic chemotherapy, did not improve patient outcomes. Results herein offer an explanation as to why EGFR inhibitors failed TNBC patients and support how combining a select antioxidant and an EGFR-specific small molecule kinase inhibitor (SMKI) could be an effective, novel therapeutic strategy. Treatment with CAT-SKL—a re-engineered protein form of the antioxidant enzyme catalase—inhibited cancer stem-like cells (CSCs), and treatment with the EGFR-specific SMKI erlotinib inhibited non-CSCs. Thus, combining the antioxidant CAT-SKL with erlotinib targeted both CSCs and bulk cancer cells in cultures of EGFR-expressing TNBC-derived cells. We also report evidence that the mechanism for CAT-SKL inhibition of CSCs may depend on antioxidant-induced downregulation of a short alternative mRNA splicing variant of the methyl-CpG binding domain 2 gene, isoform MBD2c.

    2005-07-01

    Eicosapentaenoic acid is an omega-3 fatty acid, a group of fatty acids characterized by a double bond that sits three carbons down from the n terminal of the molecule. Derived from dark, rich fish, eicosapentaenoic acid has received increasing attention as a therapy for the cancer anorexia/weight loss syndrome. Multiple studies, including laboratory and preliminary clinical studies suggest this fish oil derivative may benefit cancer patients. Recently, however, three large comparative studies suggest that eicosapentaenoic acid is relatively ineffective for treating this syndrome. In view of these recent results, the goals of this review are as follows: (1) to provide background on the mandate for further study of the cancer-associated anorexia/weight loss syndrome; (2) to review the preliminary data that have suggested that eicosapentaenoic acid is a promising agent for treating this syndrome; (3) to review the methodology and findings of the more recent, definitive clinical trials; (4) to discuss and speculate on why the earlier positive findings drew conclusions that are discrepant from the results of more recent comparative clinical studies.

    The study sought to evaluate the quality of life of women treated surgically for breast cancer at the State Oncology Hospital of Reference in São Luís in the State of Maranhão. The quality of life was assessed by the Functional Assessment of Cancer Therapy-Breast (FACT-B). The variables were expressed as mean and standard deviation, and statistical analysis consisted of the ANOVA or Kruskal Wallis test and the Student t or Mann-Whitney test. The level of significance was α < 5%. For statistical tests Stata 9.0 and BioEstat 5.0 were used. 197 women with mean age of 53.0 ± 11.7 years participated. The mean values of the FACT-B revealed a good quality of life trend, though the emotional domain was most prejudiced and the cancer sub-scale the most favorable. The type of surgery influenced the social, emotional and cancer sub-scale domain. Non-conservative surgery revealed the worst quality of life levels. A statistically significant relationship between duration of surgery and the physical, emotional and functional domains and between duration of surgery and the scores of the FACT-B was detected. Adjuvant treatment influenced all domains of FACT-B. Quality of life was relatively good, but was negatively impacted by non-conservative surgery, the shortest time between surgery and the adjuvant therapies.

    Hypoxia is a major cause of treatment resistance in breast cancer. Single-walled carbon nanotubes (SWCNTs) exhibit unique properties that make them promising candidates for breast cancer treatment. In the present study, a new functionalized single-walled carbon nanotube carrying oxygen was synthesized; it was determined whether this material could increase chemosensitivity and radiosensitivity of human breast cancer cell lines, and the underlying mechanisms were investigated. MDA-MB-231 cells growing in folic acid (FA) free medium, MDA-MB-231 cells growing in medium containing FA and ZR-75-1 cells were treated with chemotherapy drugs or radiotherapy with or without tombarthite-modified-FA-chitosan (R-O2-FA-CHI)-SWCNTs under hypoxic conditions, and the cell viability was determined by water-soluble tetrazolium salts-1 assay. The cell surviving fractions were determined by colony forming assay. Cell apoptosis induction was monitored by flow cytometry. Expression of B-cell lymphoma 2 (Bcl-2), survivin, hypoxia-inducible factor 1-α (HIF-1α), multidrug resistance-associated protein 1 (MRP-1), P-glycoprotein (P-gp), RAD51 and Ku80 was monitored by western blotting. The novel synthesized R-O2-FA-CHI-SWCNTs were able to significantly enhance the chemosensitivity and radiosensitivity of human breast cancer cell lines and the material exhibited its expected function by downregulating the expression of Bcl-2, survivin, HIF-1α, P-gp, MRP-1, RAD51 and Ku80.

    Objective:hTe aim of this study was to determine whether the EGFR statuscould significantly predict some benefit in overall survival and response to cetuximab in advanced GC xenografts.Methods: Two hundred xenografts derived from 20 GC patients were established. Then they were divided into cetuximab treated group and control group randomly.Results:Among the cetuximab treated group, 4 GC cases were identified responded to cetuximab.hTose cetuximab treated PDX models had longer OS than non-treated. High EGFR mRNA expression and immunohistochemistry score are more prone to response to cetuximab. EGFR amplification, mRNA and protein overexpression were associated with the OS in cetuximab treated PDX models. Moreover, in the PDX models derived from EGFR ampliifcation, mRNA or protein overexpression cases, the OS is signiifcantly different between the cetuximab treated and control group, while the OS in not statistically different in other cases.Conclusion:EGFR status predicts sensitivity to therapy and survival in GC treated with cetuximab, especially the mRNA and protein expression level.

    ABSTRACT This study evaluated the prognostic significance of the maximum standardized uptake value of the primary site (pSUVmax) in 18F-fluorodeoxyglucose positron emission tomography (FDG-PET) scans of patients with oropharyngeal or hypopharyngeal cancer who were treated using definitive radiotherapy. The study included 86 patients who were primarily treated with radiotherapy for oropharyngeal or hypopharyngeal cancer. Sixty-nine patients underwent concurrent chemotherapy. The associations between pre-treatment pSUVmax and treatment outcomes were evaluated. The most appropriate pSUVmax cut-off value for predicting disease-free survival (DFS) and local control (LC) was selected using receiver operating characteristic (ROC) curves. The median follow-up time for surviving patients was 60 months, while the median survival time in the entire patient cohort was 55 months. A pSUVmax cut-off value of 9.0 showed the best discriminative performance. Five-year OS and DFS rates were 65.9% and 60.0%, respectively. In univariate analyses, pSUVmax (p = 0.009), T-stage (p = 0.001), N-stage (p = 0.039), and clinical stage (p = 0.017) were identified as significant prognostic predictors for DFS. The multivariate analysis did not identify any statistically significant factors, but the association between pSUVmax and DFS was borderline significant (p = 0.055). Interestingly, pSUVmax was predictive of local controllability in T1–T2 disease (p = 0.024), but there was no significant association for T3–T4 disease (p = 0.735). In this study, pSUVmax was predictive of DFS and LC in patients with oropharyngeal or hypopharyngeal cancer that was treated with definitive radiotherapy. pSUVmax was strongly associated with LC in T1–T2 disease.

    The purpose of this study was to identify tools for the assessment of nutritional status in head and neck cancer patients, to evaluate the impact of malnutrition on therapeutic management and quality of life and to propose a simple screening approach adapted to routine clinical practice. The authors conducted a review of the literature to identify tools for the assessment of nutritional status in head and neck cancer patients published in French and English. Articles were obtained from the PubMed database and from the references of these articles and selected journals, using the keywords: "nutritional assessment", and "head and neck" and "cancer". Anthropometric indices, laboratory parameters, dietary intake assessment, clinical scores and nutritional risk scores used in patients with head and neck cancers are presented. The relevance of these tools in clinical practice and in research is discussed, together with the links between nutritional status and quality of life. This article is designed to help teams involved in the management of patients with head and neck cancer to choose the most appropriate tools for assessment of nutritional status according to their resources and their objectives.

  13. Re-programming tumour cell metabolism to treat cancer: no lone target for lonidamine

    Tumour cell metabolism is very different from normal cell metabolism; cancer cells re-programme the metabolic pathways that occur in normal cells in such a manner that it optimizes their proliferation, growth and survival. Although this metabolic re-programming obviously operates to the advantage of the tumour, it also offers unique opportunities for effective cancer therapy. Molecules that target the tumour cell-specific metabolic pathways have potential as novel anti-cancer drugs. Lonidamine belongs to this group of molecules and is already in use in some countries for cancer treatment. It has been known for a long time that lonidamine interferes with energy production in tumour cells by inhibiting hexokinase II (HKII), a glycolytic enzyme. However, subsequent studies have uncovered additional pharmacological targets for the drug, which include the electron transport chain and the mitochondrial permeability transition pore, thus expanding the pharmacological effects of the drug on tumour cell metabolism. A study by Nancolas et al. in a recent issue of the Biochemical Journal identifies two additional new targets for lonidamine: the pyruvate transporter in the mitochondria and the H+-coupled monocarboxylate transporters in the plasma membrane (PM). It is thus becoming increasingly apparent that the anti-cancer effects of lonidamine do not occur through a single target; the drug works at multiple sites. Irrespective of the molecular targets, what lonidamine does in the end is to undo what the tumour cells have done in terms of re-programming cellular metabolism and mitochondrial function.

    2016-04-01

    Medical or surgical castration serves as the backbone of systemic therapy for advanced and metastatic prostate cancer, taking advantage of the importance of androgen signaling in this disease. Unfortunately, resistance to castration emerges almost universally. Despite the development and approval of new and more potent androgen synthesis inhibitors and androgen receptor (AR) antagonists, prostate cancers continue to develop resistance to these therapeutics, while often maintaining their dependence on the AR signaling axis. This highlights the need for innovative therapeutic approaches that aim to continue disrupting AR downstream signaling but are orthogonal to directly targeting the AR itself. In this review, we discuss the preclinical research that has been done, as well as clinical trials for prostate cancer, on inhibiting several important families of AR-interacting proteins, including chaperones (such as heat shock protein 90 (HSP90) and FKBP52), pioneer factors (including forkhead box protein A1 (FOXA1) and GATA-2), and AR transcriptional coregulators such as the p160 steroid receptor coactivators (SRCs) SRC-1, SRC-2, SRC-3, as well as lysine deacetylases (KDACs) and lysine acetyltransferases (KATs). Researching the effect of-and developing new therapeutic agents that target-the AR signaling axis is critical to advancing our understanding of prostate cancer biology, to continue to improve treatments for prostate cancer and for overcoming castration resistance.

    A significant percentage of breast cancer victims will suffer from metastases indicating that new approaches to preventing breast cancer metastasis are thus needed. Dietary stearate (ST) and chemotherapy have been shown to reduce breast cancer metastasis. We tested the complementary use of dietary ST with a taxol-based chemotherapy which work through separate mechanisms to reduce breast cancer metastasis. We therefore carried out a prevention study in which diets were initiated prior to human MDA-MB-435 cancer cells being injected into the host and a treatment study in which diets were combined with paclitaxel (PTX). Using an orthotopic athymic nude mouse model and three diets [corn oil (CO) control diet, low fat (LF) or ST] the prevention study demonstrated that the ST diet decreased the incidence of lung metastasis by 50 % compared to both the LF and CO diets. The ST diet also reduced the number and size of metastatic lung nodules compared to the LF diet. Results of the treatment study indicated that both the CO and ST diets decreased the number of mice with lung metastasis compared to the LF diet. Both CO and ST also decreased the number of lung metastases per mouse compared to the LF diet however only the ST diet cohort was significant. Histomorphometric analysis of the lung tumor tissue indicated that the ST diet plus PTX decreased angiogenesis compared to the LF diet plus PTX. In conclusion these results support combining diet with chemotherapy in both treatment and prevention settings.

    Full Text Available Hürthle cell thyroid cancer (HCTC is a less common form of differentiated thyroid cancer. It rarely metastasizes to the liver, and when it does, the metastasis is almost never isolated. Here we report a 62-year-old male with widely invasive Hürthle cell thyroid cancer, who underwent total thyroidectomy and received adjuvant treatment with I-131 with posttreatment scan showing no evidence of metastatic disease. His thyroglobulin however continued to rise after that and eventually an isolated liver metastasis was identified. He underwent laparoscopic microwave ablation of the liver metastasis, with dramatic decline in thyroglobulin and no structural disease identified to date. This case highlights the rare occurrence of isolated liver metastasis from HCTC and also illustrates the utility of thermoablation as an alternative to surgical resection in the treatment of small isolated liver metastases from HCTC.

    Lymphoma of the uterine cervix is very rare. We report a case of diffuse large B cell lymphoma (DLBCL) involving the uterine cervix treated at a newly commissioned semiurban cancer centre in north India in 2015. Data for this study was obtained from the hospital electronic medical records and the patient's case file. We also reviewed published case reports of uterine and cervical lymphoma involving forty-one patients. We treated a case of stage IV DLBCL cervix with six cycles of R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisolone) and intrathecal methotrexate followed by consolidation with radiotherapy. The patient showed complete response to chemotherapy. We conclude that, in advanced stage lymphoma involving uterus and cervix, combination of chemotherapy and radiotherapy is effective in short term. PMID:27597906

    Full Text Available This report presents a case that shows a significant anticancer effect of Korean medicine therapy (KMT. A 79-year-old man, who was diagnosed as stage Ⅳ non-small cell lung cancer (NSCLC in December 2012, was treated with KMT including intravenous pharmacopunctures and oral herbal medicine from February 22, 2013, until September 2013 without any surgical intervention, chemotherapy or radiotherapy. The intravenous pharmacopunctures were the wild ginseng pharmacopuncture, Cordyceps sinensis pharmacopuncture and Trichosanthes kirilowii pharmacopuncture. The oral herbal medicine used was soramdan, made of cultivated wild ginseng. The effectiveness of this therapy was evaluated with computed tomography and the Eastern Cooperative Oncology Group (ECOG performance scale. The size of the tumor mass was markedly decreased and the ECOG performance scale was also improved. These results suggest that KMT alone can be an effective method to treat NSCLC.

    Despite a multitude of p53 immunohistochemistry (IHC) studies, data on the combined effect of nuclear p53 protein accumulation and TP53 genomic inactivation are lacking for prostate cancer. A tissue microarray including 11,152 prostate cancer samples was analyzed by p53 IHC and fluorescence in situ hybridization. Nuclear p53 accumulation was found in 10.1% of patients including 1.4% with high-level and 8.7% with low-level immunostaining. TP53 sequencing revealed that 17 of 22 (77%) cases with high-level p53 immunostaining, but only 3% (1 of 31) low-level p53 cases carried putative dominant-negative mutations. TP53 deletions occurred in 14.8% of cancers. Both deletions and protein accumulation were linked to unfavorable tumor phenotype and prostate specific antigen (PSA) recurrence (pp53 positivity (8.7%) had identical risks of PSA recurrence, which were markedly higher than in cancers without p53 alterations (pp53 deletion and low-level p53 positivity (1.5%) had a worse prognosis than patients with only one of these alterations (pp53 immunostaining or homozygous inactivation through deletion of one allele and disrupting translocation involving the second allele had the worst outcome, independent from clinical and pathological parameters. These data demonstrate a differential clinical impact of various TP53 alterations in prostate cancer. Strong p53 immunostaining-most likely accompanying dominant negative or oncogenic p53 mutation-has independent prognostic relevance and may thus represent a clinical useful molecular feature of prostate cancer.

    Objectives: This article reviews pharmacology, pharmacokinetic properties, clinical efficacy, and safety in metastatic breast cancer patients, as well as the predictive biomarkers for outcome of treatment with pemetrexed-based regimens. Methods: PubMed, Embase, OVID, and the Cochrane Library databases were searched from the beginning of each database without any limitations to the date of publication. Search terms were‘‘pemetrexed’’ or‘‘LY231514’’ or“Alimta”,“metastatic breast cancer”, and“advanced breast cancer”. Results: There were 15 studies (n ¼ 1002) meeting our criteria for evaluation. Eight single-agent trials (n ¼ 551) and seven using combinations with other agents (n ¼ 451) were identified that evaluated pemetrexed for use in patients with metastatic breast cancer. Response rates to pemetrexed as a single agent varied from 8%to 31%, and with combination therapy have been reported to be between 15.8% and 55.7%. With routine supplementation of patients with folic acid, dexamethasone, and vitamin B12, the toxicity profile of these patients was mild, including dose-limiting neutropenia and thrombocytopenia, as well as lower grades of reversible hepatotoxicity and gastrointestinal toxicity. Expression of thymidylate synthase (TS) and other biomarkers are associated with the prognosis and sensitivity for pemetrexed in breast cancer. Conclusion: Pemetrexed has shown remarkable activity with acceptable toxicities for treatment of metastatic breast cancer patients. Translational research on pemetrexed in breast cancer identified biomarkers as well as additional genes important to its clinical activity and toxicity. Further research is needed to clarify the role of pemetrexed in breast cancer treatment in order to guide oncologists. Copyright © 2015, Chinese Medical Association Production.

    Purpose: Cervical cancer treatment is associated with a risk of urinary adverse events (UAEs) such as ureteral stricture and vesicovaginal fistula. We sought to measure the long-term UAE risk after surgery and radiation therapy (RT), with confounding controlled through propensity-weighted models. Methods and Materials: From the Surveillance, Epidemiology, and End Results (SEER)-Medicare database, we identified women ≥66 years old with nonmetastatic cervical cancer treated with simple surgery (SS), radical hysterectomy (RH), external beam RT plus brachytherapy (EBRT+BT), or RT+surgery. We matched them to noncancer controls 1:3. Differences in demographic and cancer characteristics were balanced by propensity weighting. Grade 3 to 4 UAEs were identified by diagnosis codes plus treatment codes. Cumulative incidence was measured using Kaplan-Meier methods. The hazard associated with different cancer treatments was compared using Cox models. Results: UAEs occurred in 272 of 1808 cases (17%) and 222 of 5424 (4%) controls; most (62%) were ureteral strictures. The raw cumulative incidence of UAEs was highest in advanced cancers. UAEs occurred in 31% of patients after EBRT+BT, 25% of patients after RT+surgery, and 15% of patients after RH; however, after propensity weighting, the incidence was similar. In adjusted Cox models (reference = controls), the UAE risk was highest after RT+surgery (hazard ratio [HR], 5.07; 95% confidence interval [CI], 2.32-11.07), followed by EBRT+BT (HR, 3.33; 95% CI, 1.45-7.65), RH (HR, 3.65; 95% CI, 1.41-9.46) and SS (HR, 0.99; 95% CI, 0.32-3.01). The higher risk after RT+surgery versus EBRT+BT was statistically significant, whereas, EBRT+BT and RH were not significantly different from each other. Conclusions: UAEs are common after cervical cancer treatment, particularly in patients with advanced cancers. UAEs are more common after RT, but these women tend to have the advanced cancers. After propensity weighting, the risk after RT was similar

    Liver cancer is one of the top six leading causes of cancer-related death. Radiofrequency ablation (RFA) is an important means of treating liver cancer. Residual cancer after RFA is the most frequent cause of recurrence in cases of liver cancer. The main difference between residual cancer cells and ordinary liver cancer cells is that residual cancer cells experience heat shock. The secretable form of trimeric human tumor necrosis factor-related apoptosis-inducing ligand (stTRAIL) induces apoptosis in a variety of human cancers but not in normal tissues. It has shown potent cancer-selective killing activity and has drawn considerable attention as a possible cancer therapy. In the present work, the therapeutic potential of this stTRAIL-based gene therapy was evaluated in hepatocellular carcinoma subjected to RFA. Rat bone marrow mesenchymal stem cells (BM-MSCs) were isolated and transduced with a lentiviral vector encoding stTRAIL (stTRAIL-MSCs, T-MSCs). Cells treated with heat treatment at 43 °C for 45 min served as simulated residual cancer cells. After treatment with T-MSCs, apoptosis in heat-shock-treated liver cancer cells increased significantly, and caspase-3 was upregulated. When T-MSCs were subcutaneously injected into nude mice, they localized to the tumors and inhibited tumor growth, significantly increasing survival. Collectively, the results of the present study indicate that BM-MSC can provide a steady source of stTRAIL and may be suitable for use in the prevention of the recurrence of hepatocellular carcinoma after RFA with secretable trimeric TRAIL.

    In 1% to 3% of patients with cervical intraepithelial neoplasia (CIN), vaginal intraepithelial neoplasia (VAIN) will either coexist or occur at a later date. The time interval from an earlier diagnosis of CIN 3 to a current diagnosis of VAIN 3 varies from two to 17 years. Invasive vaginal cancer occurred in a woman five years after total abdominal hysterectomy for cervical intraepithelial neoplasia. In women who have undergone total hysterectomy for cervical intraepithelial neoplasia or cervical cancer, postoperative cytologic and colposcopic follow-up of the vagina is necessary.

    Full Text Available Abstract Background Arsenic exposure increases the risk of non-cancerous and cancerous diseases. In the Antofagasta region in Chile, an established relationship exists between arsenic exposure and the risk of cancer of the bladder, lung and skin. Platinum-based drugs are first-line treatments, and many works recognise selenium as a cancer-fighting nutrient. We characterised the short-term urinary excretion amounts of arsenic, selenium and platinum in 24-h urine samples from patients with lung cancer and those with cancer other than lung treated with cisplatin or/and carboplatin. As - Se - Pt inter-element relationships were also investigated. Results The amounts of platinum excreted in urine were not significantly different between patients with lung cancer and those with other cancers treated with cisplatin, despite the significant variation in platinum amounts supplied from platinum-based drugs. In general, the analytical amounts of excreted selenium were greater than those for arsenic, which could imply that platinum favours the excretion of selenium. For other types of cancers treated with drugs without platinum, excretion of selenium was also greater than that of arsenic, suggesting an antagonist selenium-anti-cancer drug relationship. Conclusions Regards the baseline status of patients, the analytical amounts of excreted Se is greater than those for As, particularly, for cisplatin chemotherapy. This finding could imply that for over the As displacement Pt favours the excretion of Se. The analytical amounts of excreted Se were greater than those for As, either with and without Pt-containing drugs, suggesting an antagonist Se-anti-cancer drug relationship. However, it seemed that differences existed between As - Se - Pt inter-element associations in patients treated for lung cancer in comparison with those treated for cancer other than lung. Therefore, knowledge obtained in this work, can contribute to understanding the arsenic cancer

    Industrialisation, the proximity of factories to cities, and human work activities have led to a disproportionate use of substances containing heavy metals, such as cadmium (Cd), which may have deleterious effects on human health. Carcinogenic effects of Cd and its relationship with breast cancer, among other tumours, have been reported. 5-Fluorouracil (5-FU) is a fluoropyrimidine anticancer drug used to treat solid tumours of the colon, breast, stomach, liver, and pancreas. The purpose of this work was to study the effects of Cd on cell cycle, apoptosis, and gene and protein expression in MCF-7 breast cancer cells treated with 5-FU. Cd altered the cell cycle profile, and its effects were greater when used either alone or in combination with 5-FU compared with 5-FU alone. Cd significantly suppressed apoptosis of MCF-7 cells pre-treated with 5-FU. Regarding gene and protein expression, bcl2 expression was mainly upregulated by all treatments involving Cd. The expression of caspase 8 and caspase 9 was decreased by most of the treatments and at all times evaluated. C-myc expression was increased by all treatments involving Cd, especially 5-FU plus Cd at the half time of treatment. Cd plus 5-FU decreased cyclin D1 and increased cyclin A1 expression. In conclusion, our results indicate that exposure to Cd blocks the anticancer effects of 5-FU in MCF-7 cells. These results could have important clinical implications in patients treated with 5-FU-based therapies and who are exposed to high levels of Cd.

    Perfusion lymphoscintigraphy was performed by subcutaneous injection of 7.4 MBq (0.2 mCi) {sup 99m}Tc-human serum albumin ({sup 99m}Tc-HSA) in 25 patients with uterine cancer treated by operation and/or irradiation. Radioactivity at the injection site was counted for 3 min at 10 min (a) and at 3 hr (b) after injection, and the clearance of {sup 99m}Tc-HSA was defined as (1-(b)/(a))x100(%) ((a) and (b) were corrected for decay of the isotope). The clearance in legs with lymphedema was significantly more delayed than those in legs without lymphedema in patients treated with both operation and irradiation (16.6{+-}7.7% vs 34.9{+-}9.3%; p<0.01) and in patients treated with radiation therapy alone (33.1{+-}7.4 vs 48.0{+-}5.6; p<0.01). The clearances in edematous legs in a case which had developed venous occulusion after operation were 44.2% and 41.7%, which were almost the same as those in the non-edematous patients treated with operation alone. Clearance in patients treated with both operation and irradiation were significantly more delayed than those in patients treated with a single modality of operation or irradiation (30.1{+-}11.4% vs 41.9{+-}8.9%, 42.0{+-}9.7%, respectively; p<0.01). Radiation doses at points B were well correlated with clearance of {sup 99m}Tc-HSA (p<0.05). These data suggest that perfusion lymphoscintigraphy using {sup 99m}Tc-HSA is useful for evaluating the patients with lymphedema and for differentiating it from the edema caused by the other mechanisms. It is also suggested that radiation dose is one of factors in the occurrence of lymphedema. (author).

    The multikinase inhibitor sunitinib (S) seems to have promising potential in the treatment of thyroid cancer. We focused on the impact of S and/or irradiation (R) on mechanisms of apoptosis in follicular thyroid cancer cells. The effects of R, S and their combination were evaluated 2 and 4 days after treatment, using the human thyroid cancer cell line CGTH W-1. The transcription of genes involved in the regulation of apoptosis was investigated using quantitative real-time PCR. Western blot analyses of caspases and survivin were also performed. S elevated BAX (day 4), CASP9, CASP3, BIRC5 (day 4) and PRKACA (day 4) gene expression, whereas the mRNAs of BCL2, CASP8, PRKCA, ERK1, and ERK2 were not significantly changed. S, R and R+S clearly induced caspase-9 protein and elevated caspase-3 activity. Survivin was down-regulated at day 4 in control cells and the expression was blunted by S treatment. R+S induced survivin expression at day 2 followed by a reduction at day 4 of treatment. Sunitinib and the combined application with radiation induced apoptosis in follicular thyroid cancer cells via the intrinsic pathway of apoptosis. In addition, sunitinib might induce apoptosis via decreased expression of the anti-apoptotic protein survivin. These findings suggest the potential use of sunitinib for the treatment of poorly differentiated follicular thyroid carcinomas.

    Multi-modality diagnosis techniques are more and more replacing traditional medical imaging for breast cancer detection. Newly emerging advances in both intelligent cancer detection systems and lipidomics technologies offer an excellent opportunity to detect tumors and to understand regulation at the molecular level in many diseases such as cancer. In this paper, we present a detailed computer-aided diagnosis (CAD) systems combining motion artefact reduction and automated feature extraction and classification, and a novel data mining approach for visualization of gene therapy leading to apoptosis in U87 MG glioblastoma cells, a secondary tumor of breast cancer. The achieved results show that the CAD system represents a robust and integrative tool for reliable small contrast enhancing lesions. Graph-clustering methods are introduced as powerful correlation networks which enable a simultaneous exploration and visualization of co-regulation in glioblastoma data. These new paradigms are providing unique "fingerprints" by revealing how the intricate interactions at the lipidome level can be employed to induce apoptosis (cell death) and are thus opening a new window to biomedical frontiers.

    Activation of oncoproteins and inactivation of tumor suppressors induces tumorigenesis. When these events happen upstream of pRb and p53, cancer therapies may initially succeed and then fail when pRb and p53 are activated and then re-inactivated. Therapies might succeed if they remain effective when pRb and p53 are genetically inactivated.

    A 69-year-old man with perianal pain was diagnosed with an anal fistula and a rectal tumor by magnetic resonance imaging and pulmonary tuberculosis by computed tomography. A colonoscopy confirmed the presence of a circular mass in the rectum 6 cm from the anal verge. Histological examination revealed a moderately differentiated adenocarcinoma. Initially, seton drainage was used to improve the perianal pain. After 2 months of anti-tuberculosis therapy, the patient underwent low anterior resection for the rectal cancer. Six months after surgery, a perianal tumor was detected at the postoperative site of the anal fistula. Biopsy of the tumor revealed adenocarcinoma. Because the histological appearance of the second tumor was identical to the rectal cancer, it was diagnosed as a metastatic anal fistula cancer. The tumor shrunk after 3 courses of neoadjuvant chemotherapy with S-1 plus oxaliplatin (SOX) plus bevacizumab and there was no evidence of distant metastasis. Local resection of the anal fistula cancer was performed. Six months postoperatively, the patient is doing well and shows no sign of recurrence.

    Fatigue is an extremely common side effect experienced during cancer treatment and recovery. Limited research has investigated strategies stemming from complementary and alternative medicine to reduce cancer-related fatigue. This research examined the effects of Reiki, a type of energy touch therapy, on fatigue, pain, anxiety, and overall quality of life. This study was a counterbalanced crossover trial of 2 conditions: (1) in the Reiki condition, participants received Reiki for 5 consecutive daily sessions, followed by a 1-week washout monitoring period of no treatments, then 2 additional Reiki sessions, and finally 2 weeks of no treatments, and (2) in the rest condition, participants rested for approximately 1 hour each day for 5 consecutive days, followed by a 1-week washout monitoring period of no scheduled resting and an additional week of no treatments. In both conditions, participants completed questionnaires investigating cancer-related fatigue (Functional Assessment of Cancer Therapy Fatigue subscale [FACT-F]) and overall quality of life (Functional Assessment of Cancer Therapy, General Version [FACT-G]) before and after all Reiki or resting sessions. They also completed a visual analog scale (Edmonton Symptom Assessment System [ESAS]) assessing daily tiredness, pain, and anxiety before and after each session of Reiki or rest. Sixteen patients (13 women) participated in the trial: 8 were randomized to each order of conditions (Reiki then rest; rest then Reiki). They were screened for fatigue on the ESAS tiredness item, and those scoring greater than 3 on the 0 to 10 scale were eligible for the study. They were diagnosed with a variety of cancers, most commonly colorectal (62.5%) cancer, and had a median age of 59 years. Fatigue on the FACT-F decreased within the Reiki condition (P=.05) over the course of all 7 treatments. In addition, participants in the Reiki condition experienced significant improvements in quality of life (FACT-G) compared to those in

    The objective of the present study was to predict key genes in ovarian cancer before and after treatment with decitabine utilizing a network approach and to reveal the molecular mechanism. Pathogenic networks of ovarian cancer before and after treatment were identified based on known pathogenic genes (seed genes) and differentially expressed genes (DEGs) detected by Significance Analysis of Microarrays (SAM) method. A weight was assigned to each gene in the pathogenic network and then candidate genes were evaluated. Topological properties (degree, betweenness, closeness and stress) of candidate genes were analyzed to investigate more confident pathogenic genes. Pathway enrichment analysis for candidate and seed genes were conducted. Validation of candidate gene expression in ovarian cancer was performed by reverse transcriptase-polymerase chain reaction (RT-PCR) assays. There were 73 nodes and 147 interactions in the pathogenic network before treatment, while 47 nodes and 66 interactions after treatment. A total of 32 candidate genes were identified in the before treatment group of ovarian cancer, of which 16 were rightly candidate genes after treatment and the others were silenced. We obtained 5 key genes (PIK3R2, CCNB1, IL2, IL1B and CDC6) for decitabine treatment that were validated by RT-PCR. In conclusion, we successfully identified 5 key genes (PIK3R2, CCNB1, IL2, IL1B and CDC6) and validated them, which provides insight into the molecular mechanisms of decitabine treatment and may be potential pathogenic biomarkers for the therapy of ovarian cancer.

    Purpose: Cognitive impairment in cancer patients induced, at least in part, by treatment are frequently observed and likely have negative impacts on patient quality of life. Such cognitive dysfunctions can affect attention, executive functions, and memory and processing speed, can persist after treatment, and their exact causes remain unclear. The aim of this review was to create an inventory and analysis of clinical studies evaluating biological markers and risk factors for cognitive decline in cancer patients before, during, or after therapy. The ultimate objectives were to identify robust markers and to determine what further research is required to develop original biological markers to enable prevention or adapted treatment management of patients at risk. Method: This review was guided by the PRISMA statement and included a search strategy focused on three components: “cognition disorders,” “predictive factors”/“biological markers,” and “neoplasms,” searched in PubMed since 2005, with exclusion criteria concerning brain tumors, brain therapy, and imaging or animal studies. Results: Twenty-three studies meeting the criteria were analyzed. Potential associations/correlations were identified between cognitive impairments and specific circulating factors, cerebral spinal fluid constituents, and genetic polymorphisms at baseline, during, and at the end of treatment in cancer populations. The most significant results were associations between cognitive dysfunctions and genetic polymorphisms, including APOE-4 and COMT-Val; increased plasma levels of the pro-inflammatory cytokine, IL-6; anemia; and hemoglobin levels during chemotherapy. Plasma levels of specific hormones of the hypothalamo-pituitary-adrenal axis are also modified by treatment. Discussion: It is recognized in the field of cancer cognition that cancer and comorbidities, as well as chemotherapy and hormone therapy, can cause persistent cognitive dysfunction.

    A 53-year-old man with an asymptomatic anterior mediastinal tumor undergoing hemodialysis was referred to our institution. He was diagnosed with thymic basaloid carcinoma based on the findings of a chest tomography-guided biopsy and successfully treated with carboplatin (300 mg/m(2)/day) and paclitaxel (200 mg/m(2)/day) on day 1 for six three-week cycles. To our knowledge, this is the first report regarding the efficiency of a carboplatin dose-definition method based on the body surface area with paclitaxel in a hemodialysis patient. This report may therefore be useful for treating hemodialysis patients who are candidates for carboplatin and paclitaxel therapy.

    Full Text Available The search for anticancer MMP-9 inhibitors (MMPIs in food products has become a major goal for research. MMPIs in soy have been related only to saponins and isoflavones, but recently, low specific protein fractions in soybeans were shown to reduce MMP-9 activity as well. The present work aimed at comparing the MMPI potential of protein fractions (P and non-protein fractions (NP isolated from soybean seeds, before and after soaking and cooking, mimicking dietary exposures. Reverse and substrate zymography, as well as a fluoregenic DQ gelatin assay were used to evaluate MMP-9 activities. Colon cancer cell migration and proliferation was also tested in HT29 cells. Regarding MMP-9 inhibition, proteins in soy presented IC50 values 100 times lower than non-protein extracts, and remained active after cooking, suggesting that proteins may be more effective MMP-9 inhibitors than non-protein compounds. Using the determined IC50 concentrations, NP fractions were able to induce higher inhibitions of HT29 cell migration and proliferation, but not through MMP-9 inhibition, whilst protein fractions were shown to specifically inhibit MMP-9 activity. Overall, our results show that protein fractions in soybeans might have a higher role in soy-related cancer prevention as MMPIs than previously expected. Being nontoxic and active at lower concentrations, the discovery of these heat-resistant specific MMPI proteins in soy can be of significant importance for cancer preventive diets, particularly considering the increasing use of soy proteins in food products and the controversy around isoflavones amongst consumers.

    Orlistat is an orally administered anti-obesity drug that has shown significant antitumor activity in a variety of tumor cells. To identify the proteins involved in its antitumor activity, we employed a proteomic approach to reveal protein expression changes in the human ovarian cancer cell line SKOV3, following Orlistat treatment. Protein expression profiles were analyzed by 2-dimensional polyacrylamide gel electrophoresis (2-DE) and protein identification was performed on a MALDI-Q-TOF MS/MS instrument. More than 110 differentially expressed proteins were visualized by 2-DE and Coomassie brilliant blue staining. Furthermore, 71 proteins differentially expressed proteins were positively identified via mass spectrometry (MS)/MS analysis. In particular, PKM1/2, a key enzyme involved in tumorigenesis, was found to be significantly downregulated in SKOV3 cells following treatment with Orlistat. Moreover, PKM1/2 was proved to be downregulated in SKOV3 cells by western blot analysis after treatment with Orlistat. Taken together, using proteomic tools, we identified several differentially expressed proteins that underwent Orlistat-induced apoptosis, particularly PKM2. These changes confirmed our hypothesis that Orlistat is a potential inhibitor of ovarian cancer and can be used as a novel adjuvant antitumor agent.

    AIM: To evaluate the potential association of xeroderma pigmentosum group D (XPD) codon 751 variant with outcome after chemo-radiotherapy in patients with resected gastric cancer.METHODS: We used PCR-RFLP to evaluate the genetic XPD Lys751Gln polymorphisms in 44 patients with stage Ⅲ (48%) and Ⅳ (20%) gastric cancer treated with surgery following radiation therapy plus 5-fluorouracil/leucovorin based chemotherapy.RESULTS: Statistical analysis showed that 75% (12 of 16) of relapse patients showed Lys/Lys genotype more frequently (P = 0.042). The Lys polymorphism was an independent predictor of high-risk relapse-free survival from Cox analysis (HR: 3.07, 95% CI: 1.07-8.78, P =0.036) and Kaplan-Meir test (P = 0.027, log-rank test).CONCLUSION: XPD Lys751Gln polymorphism may be an important marker in the prediction of clinical outcome to chemo-radiotherapy in resected gastric cancer patients.

    To assess the effects of amifostine on salivary glands in radioactive iodine-treated differentiated thyroid cancer. We searched the MEDLINE, EMBASE and the Cochrane Library for randomized controlled clinical trials which compared the effects of amifostine with those of placebo or acid-stimulating agents. Two randomized controlled clinical trials with a total of 130 patients were included. Both studies had a low risk of bias. There were no statistically significant differences between the effects of amifostine and acid-stimulating agents on the incidence of xerostomia (RR 0.24, 95% CI 0.01 to 9.52), the decrease of scintigraphically measured uptake of {sup 99m}Tc by the parotid (RR 0.30, 95% CI -2.28 to 2.88) or submandibular glands (RR 1.90, 95% CI -1.46 to 5.26) at 12 months, or the reduction in blood pressure (RR 5.00, 95% CI 0.25 to 99.16). Neither of the included trials investigated death from any cause, morbidity, health-related quality of life or costs. The results of two randomized controlled clinical trials suggest that amifostine has no significant radioprotective effects on salivary glands in radioactive iodine treatment of differentiated thyroid cancer. The use of acid-stimulating agents to increase salivation should remain the first choice during radioactive iodine treatment of differentiated thyroid cancer. Patients should also be well informed of the importance of hydration and acid stimulation. (orig.)

    Cancer-related disseminated intravascular coagulation (DIC) is a life-threatening condition for which no effective treatment is currently available. Protein C (PC), a modulator of coagulation as well as the inflammatory system, has been successfully tested (in its activated recombinant form [a-rPC]) in sepsis-related coagulopathy, but with an increased risk for major bleeding. Plasma-derived PC (pd-PC) is more suitable than a-rPC in patients at high risk from bleeding due to its self-limiting process. We carried out a single-arm study evaluating the role of pd-PC in adult cancer patients with overt DIC. Over a period of 3 years, we treated 19 patients with overt DIC and a PC plasma concentration <50%; all received PC concentrate (Ceprotin(®), Baxter) for 72 hr in adjusted doses to restore normal PC values (70-120%). Blood coagulation, haematological tests, and the DIC score were recorded after 12, 24, 48 hr, 7 and 10 days, while clinical outcomes (bleeding, thrombosis and mortality) were recorded up to 28 days. Within 48 hr of starting pd-PC therapy, laboratory tests as well as the DIC score improved in all patients. At 28-days follow-up, no bleeding or thrombosis was observed. This is the first study to investigate the use of pd- PC for treatment of cancer-related overt DIC.

    If a mathematical model is to be used in the diagnosis,treatment,or prognosis of a disease,it must describe the inherent quantitative dynamics of the state.An ideal candidate disease is prostate cancer owing to the fact that it is characterized by an excellent biomarker,prostate-specific antigen (PSA),and also by a predictable response to treatment in the form of androgen suppression therapy.Despite a high initial response rate,the cancer will often relapse to a state of androgen independence which no longer responds to manipulations of the hormonal environment.In this paper,we present relevant background information and a quantitative mathematical model that potentially can be used in the optimal management of patients to cope with biochemical relapse as indicated by a rising PSA.

    Full Text Available Hyponatraemia has been reported with targeted therapies in cancer patients. Aim of the study was to perform an up-to-date meta-analysis in order to determine the incidence and relative risk (RR in cancer patients treated with these agents.The scientific literature regarding hyponatraemia was extensively reviewed using MEDLINE, PubMed, Embase and Cochrane databases. Eligible studies were selected according to PRISMA statement. Summary incidence, RR, and 95% Confidence Intervals were calculated using random-effects or fixed-effects models based on the heterogeneity of selected studies.4803 potentially relevant trials were identified: of them, 13 randomized phase III studies were included in this meta-analysis. 6670 patients treated with 8 targeted agents were included: 2574 patients had hepatocellular carcinoma, whilst 4096 had other malignancies. The highest incidences of all-grade hyponatraemia were observed with the combination of brivanib and cetuximab (63.4 and pazopanib (31.7, while the lowest incidence was reported by afatinib (1.7. The highest incidence of high-grade hyponatraemia was reported by cetuximab (34.8, while the lowest incidences were reported by gefitinib (1.0. Summary RR of developing all-grade and high-grade hyponatraemia with targeted agents was 1.36 and 1.52, respectively. The highest RRs of all-grade and high-grade hyponatraemia were associated with brivanib (6.5 and 5.2, respectively. Grouping by drug category, the RR of high-grade hyponatraemia with angiogenesis inhibitors was 2.69 compared to anti-Epidermal Growth Factor Receptors agents (1.12.Treatment with biological therapy in cancer patients is associated with a significant increased risk of hyponatraemia, therefore frequent clinical monitoring should be emphasized when managing targeted agents.

    Vascular endothelial growth factor-A (VEGF-A), a key regulator of tumor-induced angiogenesis, is critical for tumor growth and metastasization. The goal of the present study was to evaluate the prognostic value of VEGF single nucleotide polymorphisms (SNPs) and haplotypes for clinical recurrence after definitive radiotherapy for prostate cancer. The association of seven VEGF-A polymorphisms and their haplotypes with clinical recurrence (defined as the occurrence of local recurrence and/or distant metastases) in 496 prostate cancer patients treated with definitive radiotherapy were investigated. Genotypes were determined by 5'-nuclease (TaqMan) assays; haplotypes were analyzed using the Haploview program. Within a median follow-up time of 80 months, 44 patients (9%) developed clinical recurrences. Haplotype analysis showed two separate blocks of high-linkage disequilibrium, formed by five polymorphisms (-2578C > A, -2489C > T, -1498C > T, -634G > C, -7C > T) upstream of the coding sequence (CCCCC, ATTGC, CCCGC, ATTGT) and two polymorphisms (936C > T, 1612G > A) downstream of the coding sequence (CA, CG, TG). Carriers of at least 1 copy of the ATTGC haplotype were at higher risk of recurrence (hazard ratio [HR] 3.83; 95%CI 1.48-9.90, p=0.006); for carriers of 2 copies, the HR was 4.85 (95%CI 1.72-13.6; p=0.003). In multivariate analysis, patients harboring at least one copy of the ATTGC haplotype remained at increased risk of recurrence (HR 3.63, 95%CI 1.38-9.55, p=0.009); in patients carrying 2 copies, the HR was 4.72 (95%CI 1.64-13.6, p=0.004). Our findings indicate that the VEGF-A ATTGC haplotype may predict clinical recurrence in prostate cancer patients treated with radiotherapy. (orig.)

    Background: Breast cancer survivors make up a growing population facing treatment that poses long-standing adverse effects including chemotherapy-related body function changes and/or pain. There is limited knowledge of patients’ lived experiences of chemotherapy-induced pain (CHIP). Objective: The aim of this study was to explore CHIP and any long-standing pain experiences in the lifeworld of breast cancer survivors. Methods: Fifteen women participated in a follow-up interview a year after having experienced CHIP. They were interviewed from a lifeworld perspective; the interviews were analyzed through guided phenomenology reflection. Results: A past perspective: CHIP is often described in metaphors, leads to changes in a patient’s lifeworld, and impacts lived time. The women become entirely dependent on others but at the same time feel isolated and alone. Existential pain was experienced as increased vulnerability. Present perspective: Pain engages same parts of the body, but at a lower intensity than during CHIP. The pain creates time awareness. Expected normality in relationships/daily life has not yet been achieved, and a painful existence emerges in-between health and illness. Future perspective: There are expectations of pain continuing, and there is insecurity regarding whom to turn to in such cases. A painful awareness emerges about one’s own and others’ fragile existence. Conclusions: Experiencing CHIP can impact the lifeworld of women with a history of breast cancer. After CHIP, there are continued experiences of pain that trigger insecurity about whether one is healthy. Implications for Practice: Cancer survivors would likely benefit from communication and information about and evaluation of CHIP. PMID:26632880

  13. Targeting NK-1 Receptors to Prevent and Treat Pancreatic Cancer: A New Therapeutic Approach

    Pancreatic cancer (PC) is the fourth leading cause of cancer related-deaths in both men and women, and the 1- and 5-year relative survival rates are 25% and 6%, respectively. It is known that smoking, alcoholism and psychological stress are risk factors that can promote PC and increase PC progression. To date, the prevention of PC is crucial because there is no curative treatment. After binding to the neurokinin-1 (NK-1) receptor (a receptor coupled to the stimulatory G-protein Gαs that activates adenylate cyclase), the peptide substance P (SP)—at high concentrations—is involved in many pathophysiological functions, such as depression, smoking, alcoholism, chronic inflammation and cancer. It is known that PC cells and samples express NK-1 receptors; that the NK-1 receptor is overexpressed in PC cells in comparison with non-tumor cells, and that nanomolar concentrations of SP induce PC cell proliferation. By contrast, NK-1 receptor antagonists exert antidepressive, anxiolytic and anti-inflammatory effects and anti-alcohol addiction. These antagonists also exert an antitumor action since in vitro they inhibit PC cell proliferation (PC cells death by apoptosis), and in a xenograft PC mouse model they exert both antitumor and anti-angiogenic actions. NK-1 receptor antagonists could be used for the treatment of PC and hence the NK-1 receptor could be a new promising therapeutic target in PC.

    The aim of this study was to investigate how supplementation of diet of female Sprague-Dawley rats with different doses of conjugated linoleic acids and for a varied period of time influences breast cancer risk, fatty acids profile and lipids peroxidation in chemically induced mammary tumors. Animals were divided into nine groups with different modifications of diet (vegetable oil, 1.0 or 2.0% of CLA) and period of supplementation, which lasted after (A), before (B) and before and after (BA) carcinogenic agent--7,12-dimethylbenz[a]anthracene administration at 50th day of life. Mammary adenocarcinomas occurred in all groups, but CLA supplementation decreased the cancer morbidity. Two percent CLA seems to be excessive because of the coexisting cachexia. Two CLA isomers (9-cis, 11-trans and 10-trans, 12-cis) were detected in tumors but content of rumenic acid was higher. Dietary supplementation significantly influenced some unsaturated fatty acids content (C18:2 n-6 trans, C20:1, C20:5 n-3, C22:2), but the anti- or prooxidant properties of CLA were not confirmed. CLA can inhibit chemically induced mammary tumors development in female rats, but their cytotoxic action seems not to be connected with lipids peroxidation. CLA isomers differ with their incorporation into cancerous tissues and they influence the content of some other fatty acids.

    Suberonylanilide hydroxamic acid (SAHA) is an orally administered histone deacetylase inhibitor (HDACI) that has shown significant antitumour activity in a variety of tumour cells. To identify proteins involved in its antitumour activity, we utilized a proteomic approach to reveal protein expression changes in the human cervical cancer cell line HeLa following SAHA treatment. Protein expression profiles were analysed by 2-dimensional polyacrylamide gel electrophoresis (2-DE) and protein identification was performed on a MALDI-Q-TOF MS/MS instrument. As a result, a total of nine differentially expressed proteins were visualized by 2-DE and Coomassie brilliant blue (CBB) staining. Further, all the changed proteins were positively identified via mass spectrometry (MS)/MS analysis. Of these, PGAM1 was significantly downregulated in HeLa cells after treatment with SAHA. Moreover, PGAM1 has been proven to be downregulated in another cervical cancer cell line (CaSki) by western blot analysis. Together, using proteomic tools, we identified several differentially expressed proteins that underwent SAHA-induced apoptosis. These changed proteins may provide some clues to a better understanding of the molecular mechanisms underlying SAHA-induced apoptosis in cervical cancer.

    Perfusion lymphoscintigraphy was performed by subcutaneous injection of 7.4 MBq (0.2mCi) {sup 99m}Tc-human serum albumin ({sup 99m}Tc-HSA) on 18 patients with uterine cancer treated by operation and/or irradiation. Radioactivity at the injection site was counted for 3 min at 10 min (a) and at 3 hr (b) after injection, and the clearance of {sup 99m}Tc-HSA was defined as (1-(b)/(a)) x 100(%) ((a) and (b) were corrected for decay of the isotope). The clearance in 6 legs with lymphedema was significantly more delayed than that in 16 legs without lymphedema in the patients treated with both surgery and irradiation (16.6 +- 7.7% vs 34.9 +- 9.3%: P< 0.01). The clearances in edematous legs in a case which had developed a venous occulusion after operation were 44.2% and 41.7%, which were almost the same as those in the non-edematous patients treated with surgery alone. The clearance in patients treated with both operation and irradiation was significantly more delayed than that in patients treated with the signle modality of operation or irradiation (29.7 +- 11.9% vs 41.1 +- 7.2%, 44.5 +- 7.7%, respectively: P< 0.01). These data suggest that perfusion lymphoscintigraphy using {sup 99m}Tc-HSA is useful for evaluating patients with lymphedema and for differentiating it from edema caused by other mechanisms.

    Purpose: To assess the impact of coronary artery disease (CAD) risk factors and sequelae on the risk of all-cause mortality (ACM) in men treated for prostate cancer (PC). Methods and Materials: The study cohort comprised 5077 men with PC consecutively treated with curative intent between 1997 and 2006 at the Chicago Prostate Cancer Center. Cox and Fine and Gray's competing risks regression multivariable analyses were performed, assessing whether cardiovascular comorbidity impacted the risk of ACM and PC-specific mortality, respectively, adjusting for CAD risk factors (diabetes mellitus, hypercholesterolemia, or hypertension) and sequelae (congestive heart failure or myocardial infarction), age, year and type of treatment, and known PC prognostic factors. Results: When compared with men with no comorbidity there was a significantly increased risk of ACM in men with congestive heart failure or myocardial infarction (adjusted hazard ratio [AHR] 1.96, P<.001) and in men with diabetes mellitus (AHR 1.60, P=.03) and hypertension (AHR 1.25, P=.04). In contrast, men with hypercholesterolemia had a similar risk of ACM (AHR 0.68, P=.17) when compared with men with no comorbidity. Other factors associated with a significantly increased risk of ACM included age (AHR 1.09, P<.001), prostate-specific antigen level (AHR 1.25, P=.008), and Gleason score 8-10 disease (AHR 1.71, P=.003). Cardiovascular comorbidity did not impact the risk of PC-specific mortality. Conclusions: In addition to age and unfavorable PC prognostic factors, select CAD risk factors and sequelae are associated with an increased risk of ACM in men treated for PC. These comorbidity prognostic factors predict time courses of mortality from competing causes, which may be factored into the decision-making process when considering management options for PC in a given individual.

    Objective: To evaluate the safety, feasibility and short-term efficacy of early post-operational intraperitoneal chemotherapy (EPIC) combined with Salviae miltiorrhizae (SM) in treating patients with gastric cancer. Methods: The 136 patients enrolled were divided into 3 groups: the EPIC group, the EPVC group and the control group. The former two groups were treated with SM plus 5-FU started from the second or third day after operation for 5 continuous days by intraperitoneal infusion or intravenous dripping respectively, and the control group was untreated but conventional chemotherapy was given 3 weeks after surgical operation. Toxic and adverse effects of chemotherapy, post-operational complications, short-term survival rate and intra-abdominal tumor recurrence rate were observed and compared.Results: (1) Toxic adverse effects of chemotherapy that occurred in the EPIC group were less than those in the EPVC group significantly (P<0.05-0.01). (2) Occurrence of serious complications in the EPIC group was not higher than that in the other two groups. (3) The 1- and 2-year survival rate in the EPIC group was higher than those in the other two groups respectively (P<0.01), while the post-operational intra-abdominal recurrence rate in EPIC group was significantly lower than that in the other two groups (P<0.05). Conclusions: Combined therapy of SM and 5-FU in treating patients with gastric cancer by intraperitoneal infusion is not only safe and feasible with mild toxic and side effect, but also produces a more beneficial effects, including less intra-abdominal recurrence and satisfactory short-term survival rate .

All patients newly diagnosed with invasive breast cancer receiving tamoxifen treatment from January 1, 1998, to December 31, 2008, were selected from the National Health Insurance Research Database. The usage, frequency of service, and CHP-Ginseng prescribed across the 30,556 TMX-treated breast cancer (BC survivors were evaluated. Logistic regression was employed to estimate the odds ratios (ORs for the utilization of CHP-Ginseng. Cox’s proportional hazard regression was performed to calculate the hazard ratios (HRs for endometrial cancer associated with Ginseng use among the TMX-treated BC cohort. Results. The HR for the development of endometrial cancer among breast cancer survivors who had ever taken Ginseng after TXM treatment was significantly decreased compared to those who never used CHP. Conclusion. A significant inhibitory relationship between Ginseng consumption and subsequent endometrial cancer less than 2 years after TMX treatment was detected among BC survivors.

    Full Text Available Abstract Background This study was aimed 1 to investigate the predictive value of FDG PET/CT (fluorine-18 fluorodeoxyglucose positron emission tomography/computed tomography for histopathologic response and 2 to explore the results of FDG PET/CT by molecular phenotypes of breast cancer patients who received neoadjuvant chemotherapy. Methods Seventy-eight stage II or III breast cancer patients who received neoadjuvant docetaxel/doxorubicin chemotherapy were enrolled in this study. FDG PET/CTs were acquired before chemotherapy and after the first cycle of chemotherapy for evaluating early metabolic response. Results The mean pre- and post-chemotherapy standard uptake value (SUV were 7.5 and 3.9, respectively. The early metabolic response provided by FDG PET/CT after one cycle of neoadjuvant chemotherapy was correlated with the histopathologic response after completion of neoadjuvant chemotherapy (P = 0.002. Sensitivity and negative predictive value were 85.7% and 95.1%, respectively. The estrogen receptor negative phenotype had a higher pre-chemotherapy SUV (8.6 vs. 6.4, P = 0.047 and percent change in SUV (48% vs. 30%, P = 0.038. In triple negative breast cancer (TNBC, the pre-chemotherapy SUV was higher than in non-TNBC (9.8 vs. 6.4, P = 0.008. Conclusions The early metabolic response using FDG PET/CT could have a predictive value for the assessment of histopathologic non-response of stage II/III breast cancer treated with neoadjuvant chemotherapy. Our findings suggest that the initial SUV and the decline in SUV differed based on the molecular phenotype. Trial Registration ClinicalTrials.gov: NCT01396655

    To analyze prognostic factors for locoregional recurrence (LRR), distant metastasis (DM), and overall survival (OS) in cervical cancer patients who underwent radical hysterectomy followed by postoperative radiotherapy (PORT) in a single institute. Clinicopathologic data of 135 patients with clinical stage IA2 to IIA2 cervical cancer treated with PORT from 2001 to 2012 were reviewed, retrospectively. Postoperative parametrial resection margin (PRM) and vaginal resection margin (VRM) were investigated separately. The median treatment dosage of external beam radiotherapy (EBRT) to the whole pelvis was 50.4 Gy in 1.8 Gy/fraction. High-dose-rate vaginal brachytherapy after EBRT was given to patients with positive or close VRMs. Concurrent platinum-based chemoradiotherapy (CCRT) was administered to 73 patients with positive resection margin, lymph node (LN) metastasis, or direct extension of parametrium. Kaplan-Meier method and log-rank test were used for analyzing LRR, DM, and OS; Cox regression was applied to analyze prognostic factors. The 5-year disease-free survival was 79% and 5-year OS was 91%. In univariate analysis, positive or close PRM, LN metastasis, direct extension of parametrium, lymphovascular invasion, histology of adenocarcinoma, and chemotherapy were related with more DM and poor OS. In multivariate analysis, PRM and LN metastasis remained independent prognostic factors for OS. PORT after radical hysterectomy in uterine cervical cancer showed excellent OS in this study. Positive or close PRM after radical hysterectomy in uterine cervical cancer correlates with poor prognosis even with CCRT. Therefore, additional treatments to improve local control such as radiation boosting need to be considered.

    Background There is an association between postmenopausal tamoxifen therapy and endometrial pathologies. We investigated the usefulness of diagnostic hysteroscopy and transvaginal ultrasonography (TVS) and estimated whether diagnostic hysteroscopy improves detection of endometrial pathologies in postmenopausal breast cancer patients on tamoxifen. Methods Ninety-seven postmenopausal breast cancer patients who had been taking tamoxifen 20 mg/d for ≥6 months went through TVS, diagnostic hysteroscopy, and endometrial biopsy examinations. The presence of endometrial histopathologic features with abnormal TVS and diagnostic hysteroscopic findings were correlated. Results No endometrial cancer was found in any of the 97 patients. Fifty-three patients (54.6%) developed endometrial polyps as diagnosed histopathologically. Fifty-nine patients (60.8%) tested positive in TVS exams, of whom 43 had polyps, four had hyperplasia, and 12 atrophy. Thirty-eight patients (39.2%) tested negative in TVS exams, of whom 10had polyps, three hyperplasia, and 25 atrophy. TVS exams presented 63.6% specificity, 81.8% sensitivity, 72.9%positive-predictive value, and 73.7% negative-predictive value, whereas the corresponding values of diagnostic hysteroscopy were 100%, 98.1%, 100%, and 97.8% respectively. The correct ratio of hysteroscopy was significantly higher than that of TVS (P=0.000). Conclusions In postmenopausal breast cancer patients treated with tamoxifen, TVS alone is not sufficient for the detection of endometrial pathologies. Additional use of diagnostic hysteroscopy considerably improves the detection of polyps, thus significantly reducing the rate of false-negative findings of endometrial pathologies.

    Purpose: The current study examined the effect of recombinant human deoxyribonuclease (rhDNase) on quality of life (QOL) measures, clinical improvement, and DNA content of thick oropharyngeal secretions (OPS) in patients with head-and-neck (H and N) cancers. Methods and Materials: Thirty-six patients with local-regional advanced H and N cancer receiving chemoradiationtherapy (CRT) were randomized to receive either placebo or rhDNase. Endpoints included MD Anderson Symptom Inventory-Head and Neck (MDASI-HN) and Functional Assessment of Cancer Therapy–Head and Neck (FACT-NH) scores, along with clinical assessment and DNA concentration of OPS. Results: There were no statistically significant differences in patients' QOL outcomes over the study period. Both groups showed an increase in symptom and interference scores, although patients in the rhDNase group showed a greater decline in both scores during the 3 months posttreatment. Similarly, both groups showed a decline in physical and functional well being but recovered in the 3 months posttreatment follow-up, with the rhDNase group exhibiting speedier recovery. Patients in the rhDNase group exhibited significant clinical improvement in OPS, blindly assessed by a physician, compared with the placebo group (67% vs 27%, respectively; P=.046). The rhDNase group showed no change in OPS-DNA concentration, although the placebo group showed a significant increase in DNA concentration during the drug trial (P=.045). There was no differences in acute toxicities between the 2 groups. Conclusions: Our preliminary data suggest that rhDNase did not significantly improve study primary endpoints of QOL measures compared with the placebo group. However, there was a significant improvement in secondary endpoints of clinically assessed OPS and DNA concentration compared with placebo in H and N cancer patients treated with CRT. Further investigation in larger numbers of patients is warranted.

    Aim To assess the prevalence of metabolic syndrome (MetS) and osteoporosis in patients with prostate cancer (PCa) treated with radical radiotherapy (RT) with or without androgen deprivation therapy (ADT). Background Worldwide, the prevalence of MetS is estimated to range from 20% to 25% of the adult population. However, prevalence rates are much higher in PCa patients (pts) who undergo ADT. Materials and methods Multicentre cross-sectional study of 270 pts in Spain with PCa. Patients were divided into 3 groups based on the duration of ADT (6, 12–18, ≥24 months) and compared to a control group without ADT. MetS was defined according to NCEP ATP III criteria. Osteoporosis was assessed by DEXA. Results A total of 270 pts, treated from November 2011 to October 2012, were included. Of these, 122 pts (47%) fulfilled the criteria for MetS. The median age of this group was significantly higher (71.3 vs. 69.38 years, p = 0.028). MetS prevalence was 50% in the control group. In pts who received ADT, prevalence was 44.8% after 6 months of ADT, 45.3% after 12–18 months, and 50% after ≥24 months (pns). Most pts (168/270; 62%) underwent DEXA. Of those tested, 78 (46.4%) had osteopenia and only 11 (6.5%) had osteoporosis. Conclusions The prevalence of MetS in pts with PCa treated with radical RT was higher (47%) than in the general population. However, there were no significant differences in the duration of ADT administration. The prevalence of osteoporosis was low. These findings suggest that the prevalence of MetS in PCa patients may be higher than previously reported. PMID:26549995
