    Results from clinical trials in the 1990s led to changes in the recommended treatment for the standard therapy for stage IIB-IVA cervical cancer from radiotherapy alone to chemo-radiotherapy. We conducted the first population-based study in Canada to investigate temporal treatment patterns for cervical cancer and long-term survival in relation to these changes in the treatment guidelines. Detailed information on stage and treatment for 1085 patients diagnosed with cervical cancer in 1984-2008 and identified from the population-based Manitoba Cancer Registry (MCR) in Canada was obtained from clinical chart review and the MCR. Factors associated with receiving guideline treatment were identified using logistic regression. All cause and cervical cancer specific survival were compared in patients who were and were not treated as recommended in the guidelines, using Cox proportional hazards models. The median follow-up time was 6.4 years (range: 0.05-26.5 years). The proportion of women who received guideline treatment was 79 % (95 % confidence interval [CI]: 76-81 %). However, the likelihood of being treated according to the guidelines over time was modified by age (p cervical cancer. This was driven by lower mortality rates in cases with stage IIB-IVA tumours (all causes of death: hazard ratio [HR] = 0.60, 95 % CI: 0.43-0.82, p = 0.002; cervical cancer related death: HR = 0.64, 95 % CI: 0.44-0.93, p = 0.02). The management of cervical cancer patients in Manitoba, Canada was in good agreement with treatment guidelines although reasons for departure from the guideline recommendations could not be examined further due to lack of data. Treatment of stage IIB-IVA cervical cancers with recommended concurrent chemo-radiotherapy, which is now standard practice, was associated with substantially increased survival, although the effect of changes in clinical practice including maintenance of haemoglobin levels on improved survival cannot be ruled out as a

    Manitoba has the highest prevalence of ESRD in Canada. Northern Manitoba is a very sparsely settled area with a high proportion of aboriginal ESRD patients. Relocating to urban areas for dialysis is psychosocially and culturally stressful to patients. Delivering dialysis care in a home setting has demonstrated advantages in both clinical, economic, and health related quality of life domains. Establishing home hemodialysis in very remote communities has significant challenges, including poor and inadequate housing, unreliable water supply, limited community medical backup, and poor road access to communities especially for delivery of supplies. These challenges necessitate the development of strong community partnerships, and well documented processes for contingencies. A dedicated interdisciplinary support and training team at the urban hub is essential.

    1995-12-31

    Various types of wind energy systems were described. The most popular wind energy system uses a high speed propeller, and has a typical efficiency of 40 per cent. A 3 kW two blade propeller wind energy system was set up as a demonstration project at Fort Whyte Centre in Winnipeg, Manitoba. It generates about four per cent of the electrical requirements of the centre. Other types of wind energy systems include the Darrieus wind energy system using a wind turbine, the Savonius and Multiblade systems, and Hybrid systems. A group of wind energy systems working together is known as a wind farm; such farms have been in operation for many years in high wind areas of the USA. In Manitoba, no wind energy system operates for the sole purpose of generating and selling electricity to a local utility, but some wind energy systems can feed surplus energy into the utility system. A review of environmental impacts, economic considerations and an assessment of wind resources within Manitoba, was also provided. 4 figs.

    2003-07-01

    This presentation described the drilling activity in Manitoba from 1998 to 2002 with particular emphasis on horizontal well drilling and production by geologic formation, including the Bakken, Lodgepole and the Lower Amaranth Formations. A total of 97 wells were drilled in Manitoba in 2002. The most active drillers were EOG Resources Canada with a total of 34 wells. Tundra Oil and Gas was close behind with 28 wells, followed by Chevron Canada Resources with 21 wells. Horizontal drilling had a major impact in Manitoba between 1998-2002, representing 30 per cent of drilling activity focused on the Waskada, Virden and Daly fields. Expansion activity throughout the province contributed to the overall increase in oil production for four consecutive years. Annual production reached 650.7 10{sup 3}m{sup 3} in 2001. Manitoba's top 5 producers are Chevron Canada Resources, Tundra Oil and Gas, EOG Resources Canada, Canadian Natural Resources and NCE Petrofund. Together, they account for 89 per cent of Manitoba's production. This paper also described some of the initiatives that Manitoba's Department of Industry, Trade and Mines has taken to improve oil and gas regulations through proposed amendments to the Oil and Gas Act, a review of the Manitoba Drilling Incentive Program, battery re-permitting, and a strategy for managing orphaned wells. 3 figs.

    1991-02-01

    Fourteen female patients with primary urethral carcinoma were treated at the Manitoba Cancer Foundation in the last twenty-nine years. The relationship of natural history to the stage, location, and therapeutic modality has been reviewed. A higher stage and length of urethral involvement affected prognosis negatively, whereas lower stage had a positive prognostic effect and location of tumor had no prognostic influence. Two patients with Stage C, who failed to received inguinal node radiotherapy, died of disease recurring in the inguinal area. Patients who received inguinal radiation (3 patients Stages B, C, and D1) had no regional recurrence. It is suggested that, for all female urethral carcinoma, bilateral ilioinguinal nodes be included in the radiation field. For radical treatment, iridium 192 insertion in combination with external beam treatment is recommended.

    Energy Technology Data Exchange (ETDEWEB)

    Fox, J.

    1997-04-01

    An update of horizontal well drilling in Manitoba was provided. Manitoba`s productive formations are: (1) the Bakken Formation, (2) the Lodgepole Formation, (3) the Mission Canyon Formation, (4) the Amaranth Formation, and (5) the Melita Formation. A total of 28 exploratory wells and 29 development wells, including 11 horizontal wells were drilled in 1996. The 11 horizontal wells accounted for 30 per cent of the drilling meterage. The leading drillers for horizontal wells in Manitoba are Tundra Oil and Gas, Chevron, Anderson and HCO. Production from horizontal wells in 1996 totaled 310 cubic meter per day. To date, no horizontal wells have been drilled in the Bakken Formation. The least successful horizontal well application has been in the Lodgepole Formation. A summary of horizontal well production was provided for each Formation. 4 tabs., 10 figs.

    2005-07-01

    This paper presented data on oil and gas activities in Manitoba during 2004, the busiest year in Manitoba's oil patch since the mid 1980s. Increases in the leasing of Crown and freehold acreage were also noted, with accompanying increases in drilling activity for the latter part of 2004. Details of Crown land sales were presented, with a total of 43,725 hectares of crown oil and gas rights under lease. During 2004, over 15,000 hectares of Crown oil and gas leases were sold, the highest figures since 1997. More wells were licensed and drilled in 2004 than in any year since 1986. Overall drilling success rate was 96.7 per cent. Details of top drillers in Manitoba were presented, with drilling activity focused in Waskada and Daly fields and the Sinclair area. Oil production increased by 0.7 per cent, with 1474 wells in production. Daily oil production statistics were presented, with the total value of Manitoba's oil production being $196 million. Details of the top 5 producers were provided, in addition to details of horizontal well production. Recent developments in Sinclair Field, Pierson L. Amaranth MC 3b A Pool, Waskada L. Amaranth I Pool and Virden Lodgepole D Pool were reviewed. The Manitoba Drilling Incentive Program was discussed with reference to the following enhancements: new well incentives, horizontal well incentives; holiday oil volume accounts; and marginal well major workover programs. Various Oil and Gas Act amendments were reviewed. In addition, the Williston Basin Architecture and Hydrocarbon Potential Project was discussed. 3 figs.

    The purpose of this paper is to analyze the current evolutions on nanotechnology and its applications on cancer theragnostics.Rapid advances and emerging technologies in nanotechnology are having a profound impact on cancer treatment. Applications of nanotechnology, which include liposomes, nanoparticles, polymeric micelles, dendrimers, nanocantilever, carbon nanotubes and quantum dots have significantly revolutionized cancer theragnostics. From a pharmaceutical viewpoint, it is critical that the biodistribution of active agents has to be controlled as much as possible. This aspect is vital in order to assure the proper efficiency and safety of the anticancer agents. These biocompatible nanocomposites provide specific biochemical interactions with receptors expressed on the surface of cancer cells. With passive or active targeting strategies, an increased intracellular concentration of drugs can be achieved in cancer cells , while normal cells are being protected from the drug simultaneously. Thus, nanotechnology restricts the extent of the adverse effects of the anticancer therapy. Treatment for metastatic breast cancer, sarcoma in AIDS patients, ovarian and lung cancer is already on market or under final phases of many clinical trials, showing remarkable results. As nanotechnology is perfected, side effects due to normal cell damage will decrease, leading to better results and lengthening patient's survival.

    Full Text Available The first confirmed case of hantavirus pulmonary syndrome in Manitoba was diagnosed in 1999. To define better the risk of exposure to hantaviruses in this area, the clinical features and epidemiological factors pertaining to this case were described, and a serological survey of rodents collected near the patient's residence was undertaken. Small mammals were collected using live traps, were anesthetized via inhalation of isoflurane and were bled. Human and mouse serologies were undertaken using an ELISA to detect hantavirus-specific immunoglobulin G and/or immunoglobulin M antibodies. In addition, a full medical and epidemiological assessment, as well as individual risk factor and exposure analysis, were conducted. A 27-year-old Manitoba woman presented with severe respiratory distress and diffuse bilateral air space disease radiologically. Despite extremely aggressive measures, including mechanical ventilation, antibiotics, fluid management and inotropic support, the patient's condition rapidly deteriorated, and she died 8 h after admission. Hantavirus pulmonary syndrome was confirmed by the detection of immunoglobulin M and immunoglobulin G antibodies to the Sin Nombre virus (SNV in her sera and by the demonstration of SNV genomic sequences in her lung tissue. Exposure to hantavirus likely occurred in and around the home or in the rural area in which she resided. A total of 252 small mammals, primarily deer mice (Peromyscus maniculatus, were collected from 17 different sites at or near where the patient lived. Antibodies to SNV were detected in 28 of 244 (11.5% deer mice, which were collected within 9 km of the residence of the fatal case, indicating that these rodents are a significant reservoir for SNV in this area.

    2013-01-01

    Comprehensively review the evidence regarding the use of ayahuasca, an Amerindian medicine traditionally used to treat many different illnesses and diseases, to treat some types of cancer. An in-depth review of the literature was conducted using PubMed, books, institutional magazines, conferences and online texts in nonprofessional sources regarding the biomedical knowledge about ayahuasca in general with a specific focus in its possible relations to the treatment of cancer. At least nine case reports regarding the use of ayahuasca in the treatment of prostate, brain, ovarian, uterine, stomach, breast, and colon cancers were found. Several of these were considered improvements, one case was considered worse, and one case was rated as difficult to evaluate. A theoretical model is presented which explains these effects at the cellular, molecular, and psychosocial levels. Particular attention is given to ayahuasca's pharmacological effects through the activity of N,N-dimethyltryptamine at intracellular sigma-1 receptors. The effects of other components of ayahuasca, such as harmine, tetrahydroharmine, and harmaline, are also considered. The proposed model, based on the molecular and cellular biology of ayahuasca's known active components and the available clinical reports, suggests that these accounts may have consistent biological underpinnings. Further study of ayahuasca's possible antitumor effects is important because cancer patients continue to seek out this traditional medicine. Consequently, based on the social and anthropological observations of the use of this brew, suggestions are provided for further research into the safety and efficacy of ayahuasca as a possible medicinal aid in the treatment of cancer.

  6. Laetrile treatment for cancer.

    Science.gov (United States)

    Milazzo, Stefania; Horneber, Markus

    2015-04-28

    Laetrile is the name for a semi-synthetic compound which is chemically related to amygdalin, a cyanogenic glycoside from the kernels of apricots and various other species of the genus Prunus. Laetrile and amygdalin are promoted under various names for the treatment of cancer although there is no evidence for its efficacy. Due to possible cyanide poisoning, laetrile can be dangerous. To assess the alleged anti-cancer effect and possible adverse effects of laetrile and amygdalin. We searched the following databases: CENTRAL (2014, Issue 9); MEDLINE (1951-2014); EMBASE (1980-2014); AMED; Scirus; CINAHL (all from 1982-2015); CAMbase (from 1998-2015); the MetaRegister; the National Research Register; and our own files. We examined reference lists of included studies and review articles and we contacted experts in the field for knowledge of additional studies. We did not impose any restrictions of timer or language. Randomized controlled trials (RCTs) and quasi-RCTs. We searched eight databases and two registers for studies testing laetrile or amygdalin for the treatment of cancer. Two review authors screened and assessed articles for inclusion criteria. We located over 200 references, 63 were evaluated in the original review, 6 in the 2011 and none in this update. However, we did not identify any studies that met our inclusion criteria. The claims that laetrile or amygdalin have beneficial effects for cancer patients are not currently supported by sound clinical data. There is a considerable risk of serious adverse effects from cyanide poisoning after laetrile or amygdalin, especially after oral ingestion. The risk-benefit balance of laetrile or amygdalin as a treatment for cancer is therefore unambiguously negative.

    Breast cancer is the most common cancer in women, and the second most common cause of cancer death after lung cancer. Improvements in the outcome of breast cancer mean that more patients are living longer and are, therefore, at risk of developing a second malignancy. The aim of this review is to present the current understanding of the risk of lung cancer arising in patients previously treated for early stage breast cancer. We review data on the effect of treatment factors (ie, surgery type, radiotherapy technique, and adjuvant chemotherapy) and patient factors (ie, age and smoking) on the risk of developing a subsequent lung cancer. The evidence suggests that older radiotherapy techniques were associated with a substantially increased risk of developing lung cancer in the ipsilateral lung, but there is no clear evidence of an increased risk with modern techniques. Smoking is an important risk factor, and increases the risk of lung cancer in those receiving radiotherapy. Adjuvant chemotherapy is not significantly associated with an increased risk. The risk of developing lung cancer increases with time elapsed since treatment, but any effect of age at treatment is unclear.

    To help understand physician movement out of Manitoba by determining the factors that influence Manitoba medical graduates' choices about practice locations. Cross-sectional, within-stage, mixed-model survey. Manitoba. All University of Manitoba medical graduates from classes 1998 to 2009 for whom we had valid contact information (N = 912 of 943 graduates) were invited in August 2009 to participate in a survey. Demographic information; ratings, on a 5-point scale, of the importance when choosing first practice locations of 12 practice characteristics, 3 recruitment strategies, and 4 location characteristics listed in the survey; free-text narratives on unlisted factors; and estimates of likely practice location upon completion of training for recent graduates still in residency training. Completed surveys were received from 331 (35.1%) graduates of the surveyed classes, 162 (53.3%) of whom chose Manitoba for their first practice location. Multiple regression analyses indicated that graduates choosing Manitoba for their first practice location were significantly more likely to have done their residency training in Manitoba (P choice of Manitoba as their first practice location, regardless of graduates' rating of the importance of being near family or friends. Graduates' narratives provided insights into the complexities of choosing practice locations and enhanced the interpretive and theoretical validity of the study findings. More extensive studies involving all Canadian residents could further define the role residency location plays in physician practice location.

    Germ-cell tumours (GCTs) are the most common type of cancer in young men. Since the late 1970s, disseminated GCT have been a paradigm for curable metastatic cancer and metastatic GCTs are highly curable with cisplatin-based chemotherapy followed by surgical resection of residual masses. Patients' prognosis is currently assessed using the International Germ-Cell Consensus Classification (IGCCC) and used to adapt the burden of chemotherapy. Approximately 20% of patients still do not achieve cure after first-line cisplatin-based chemotherapy, and need salvage chemotherapy (high dose or standard dose chemotherapy). Clinical stage I testicular cancer is the most common presentation and different strategies are proposed: adjuvant therapies, surgery or surveillance. During the last three decades, clinical trials and strong international collaborations lead to the development of a consensus in the management of GCTs.

  12. Towards a Manitoba Hydro boreal woodland caribou strategy: Outcomes from Manitoba Hydro boreal woodland caribou workshop

    2012-03-01

    Full Text Available Manitoba Hydro is responsible for the continued supply of energy to meet the needs of the province and is committed to protecting the environment when planning the construction and operation of its facilities. Corporate policy dictates ongoing improvement of Environmental Management Systems (EMS in order to meet or surpass regulatory requirements. Environmental objectives are reviewed annually and programs are modified when necessary to address improvements in environmental performance. Manitoba Hydro plans and constructs major transmission projects throughout northern Manitoba which includes areas occupied by boreal woodland caribou. In recognition of the potential issues associated with hydro transmission construction in boreal caribou range, Manitoba Hydro hosted an expert workshop on May 8, 2007 to provide objective advice in the development of a draft corporate strategy that effectively directs targeted monitoring and research for environmental assessment and mitigation. The workshop focused on assessing the potential threats to boreal woodland caribou from a transmission line construction and operation perspective, and identifying appropriate approaches in site selection and environmental assessment (SSEA and long-term monitoring and research. A total of nine threat categories were reviewed to determine the degree and magnitude of potential effects that may result from transmission construction and operation; and of the original nine, five final threat categories were delineated. The main elements of the workshop provided strategic approaches for proactive pre-construction monitoring, research on recruitment and mortality for local populations impacted by ROWs and control areas, and various habitat monitoring, management, and mitigation techniques. Research and monitoring priorities have been identified and continued collaboration with Manitoba Conservation and other land users were also identified.

    The success of cancer therapy can be difficult to predict, as its efficacy is often predicated upon characteristics of the cancer, treatment, and individual that are not fully understood or are difficult to ascertain. Monitoring the response of disease to treatment is therefore essential and has traditionally been characterized by changes in tumor volume. However, in many instances, this singular measure is insufficient for predicting treatment effects on patient survival. Molecular imaging allows repeated in vivo measurement of many critical molecular features of neoplasm, such as metabolism, proliferation, angiogenesis, hypoxia, and apoptosis, which can be employed for monitoring therapeutic response. In this review, we examine the current methods for evaluating response to treatment and provide an overview of emerging PET molecular imaging methods that will help guide future cancer therapies.

    2013-02-01

    Evidence shows that older patients are discriminated against when it comes to cancer treatment. A pilot project was commissioned by the Department of Health in partnership with Macmillan Cancer Support and Age UK. The project involved staff, including nurses, from five cancer networks in England examining ways to improve care for this patient group. Drawing on approaches used in geriatric medicine, patients' needs in accessing treatment were explored by conducting assessments and, for example, providing taxis for hospital appointments and practical support from voluntary organisations. Challenges for nurses included lack of training in patient screening and the extra workload caused by the assessments. The report on the pilot project concluded that involving elderly care specialists and using comprehensive geriatric assessments were useful approaches in the care of older cancer patients.

    Full Text Available Hyperthermia is potentially an effective method for the treatment of cancer, especially breast cancer tumors. One of the most attractive attributes of hyperthermia is the possibility of providing therapeutic benefit noninvasively, minimizing side effects. To be effective, a hyperthermia treatment must selectively heat the cancerous tissue, elevating the temperature in the tumor without exposing healthy tissue to excessive temperature elevations. In this paper, a suggested simple model of Annular Phased Array (APA using eight half wavelength linear dipoles is presented. New software (COMSOL MULTIPHYSICS is used to calculate the temperature distribution inside a model of a three layered breast (skin, breast tissue, and tumor. In addition, the effect of changing the amplitude and phases of the array elements on the temperature distributions and the conditions on the values of the phases are demonstrated in order to achieve the objective of hyperthermia for breast tumor treatment.

    As cancer patients are living longer and the number of cancer survivors increases, more secondary complications related to cancer and its treatments are being recognized. A large number of neuromuscular processes, stemming from cancer itself, from secondary metabolic effects, from paraneoplastic syndromes, from preexisting conditions, or from adverse effects related to cancer treatments, can affect the peripheral nervous system at any level. Electrodiagnostic tools such as nerve conduction studies and needle electromyography are uniquely suited to assess the function of the peripheral nervous system and are valuable tools in confirming and defining neuromuscular dysfunction and in helping guide oncologic and physiatric treatment and prognosis for the cancer rehabilitation patient.

    2006-12-01

    The knowledge acquired in the past few years on the regulatory mechanisms of cancer growth and spreading have started to be translated in the development of a new therapeutic modality directed against previously defined molecular targets, now defined as "target therapy", thus introducing a truly revolutionary concept in the anticancer therapeutic strategies. The novel molecular targeted drugs are usually integrated in therapeutic regimens that combine such novel agents with the conventional chemotherapy and radiotherapy, and several studies have now demonstrated their efficacy in the clinical practice. The future goal of cancer therapy will be the tailoring of treatments based on the specific molecular features of the tumor of each patient, with the aim to obtain the maximum therapeutic efficacy with the lowest toxicity.

    Since the development of hybridoma technology in 1975 monoclonal antibodies with pre-defined specificity can be produced. Only twenty years later did it become possible to make therapeutic use of monoclonal antibodies in oncology. To this end it was necessary to attach the antigen-binding site of a mouse antibody onto the scaffold of a human antibody molecule. Such chimeric or "humanized" antibodies may be used in passive immunotherapy without eliciting an immune response. Rituximab and trastuzumab are such humanized antibodies. They are used today routinely in the treatment of malignant lymphoma and breast cancer, respectively. These antibodies are usually used in combination with conventional cytostatic anticancer drugs.

    Full Text Available GI cancer is not one cancer but is a term for the group of cancers that affect the digestive system including gastric cancer (GC, colorectal cancer (CRC, hepatocellular carcinoma (HCC, esophageal cancer (EC, and pancreatic cancer (PC. Overall, the GI cancers are responsible for more cancers and more deaths from cancer than any other organ. 5 year survival of these cancers remains low compared to western world. Unlike the rest of the world where organ based specialities hepatobiliary, pancreatic, colorectal and esophagogastric exist , these cancers are managed in India by either a gastrointestinal surgeons, surgical oncologist, or a general surgeon with varying outcomes.The aim of this review was to collate data on GI cancers in indian continent. In colorectal cancers, data from tertiary care centres identifies the unique problem of mucinous and signet colorectal cancer. Results of rectal cancer resection in terms of technique (intersphincteric resection, extralevator aper, minimal invasive approach to be comparable with world literature. However long term outcome and data regarding colon cancers and nationally is needed. Gastric cancer at presentation are advanced and in surgically resected patients, there is need for a trial to compare chemoradiation vs chemotherapy alone to prevent loco regional recurrence. Data on minimal invasive gastric cancer surgery may be sparse for the same reason. Theree is a lot of data on surgical techniques and perioperatve outcomes in pancreatic cancer. There is a high volume of locally advanced gallbladder cancers with efforts on to decide whether neoadjuvant chemotherapy or neoadjuvant chemoradiotherapy is better for down staging. Considering GI cancers, a heterogeneous disease with site specific treatment options and variable outcomes, the overall data and outcomes are extremely variable. Young patients with pathology unique to the Indian subcontinent (for example, signet ring rectal cancer, GBCs need focussed

  5. Treatment protocols for cervical cancer

    2002-01-01

    Full Text Available Introduction Cervical cancer is the second most common cancer in women worldwide and the second cause of cancer death among women. About 95% (90% in developed countries of invasive carcinomas are of sqamous types, and 5% (10% in developed countries are adenocarcinomas. FIGO classification of cervical carcinomas, based on clinical staging and prognostic factor dictate therapeutic procedures and help in designing treatment protocols. Therapeutic modalities Surgical therapy includes conization, radical hysterectomy with pelvic lymphadenectomy and palliative operation urinary diversion and colostomy. Radiotherapy, brachytherapy and teletherapy are most recently combined with chemotherapy as concurrent chemoradiation. Discussion and conclusion No change in therapeutic modalities will ever decrease mortality rate of cervical carcinoma as much as education, prevention and early screening. The 5-year survival for locally advanced disease has not improved during the last 40 years as a result of failure to deliver therapy to the paraaortic region. Paraaortic lymph nodes should be evaluated before therapy planning by different imaging procedures, or more exactly by surgical staging: laparoscopy or laparotomy. Radical operations of cervical carcinoma should be performed by experienced surgeons, educated for this type of operation, with sufficient number of cases.

    Systematic overview of the application of ultrasound and MRI in the diagnosis and treatment of diseases of the lower urinary tract. Detailed information on image-guided therapies, including focused ultrasound, photodynamic therapy, and microwave and laser ablation. Numerous high-quality illustrations based on high-end equipment. Represents the state of the art in Non Invasive Imaging and Minimally Invasive Ablation Treatment (MIAT). Image-Guided Prostate Cancer Treatments is a comprehensive reference and practical guide on the technology and application of ultrasound and MRI in the male pelvis, with special attention to the prostate. The book is organized into three main sections, the first of which is devoted to general aspects of imaging and image-guided treatments. The second section provides a systematic overview of the application of ultrasound and MRI to the diagnosis and treatment of diseases of the lower urinary tract. Performance of the ultrasound and MRI studies is explained, and the normal and abnormal pathological anatomy is reviewed. Correlation with the ultrasound in the same plane is provided to assist in understanding the MRI sequences. Biopsy and interventional procedures, ultrasound-MRI fusion techniques, and image-guided therapies, including focused ultrasound, photodynamic therapy, microwave and laser ablation, are all fully covered. The third section focuses on securing treatment effectiveness and the use of follow-up imaging to ensure therapeutic success and detect tumor recurrence at an early stage, which is vital given that prompt focal treatment of recurrence is very successful. Here, particular attention is paid to the role of Doppler ultrasound and DCE-MRI technologies. This book, containing a wealth of high-quality illustrations based on high-end equipment, will acquaint beginners with the basics of prostate ultrasound and MRI, while more advanced practitioners will learn new skills, means of avoiding pitfalls, and ways of effectively

    Lung cancer is one of the most common and deadliest forms of cancer. It accounts for 13% of all new cancer cases and 19% of cancer-related deaths. In India, lung cancer constitutes 6.9% of all new cancer cases and 9.3% of all cancer cases. There has also been a dramatic rise worldwide in both the absolute and relative frequencies of lung cancer occurrence. In 1953 it became the most common cause of cancer mortality in men. By 1985, it became the leading cause of cancer deaths in women, causing almost twice as many deaths as breast cancer. The demographic proifle of lung cancer has changed greatly over the years; however, methods for diagnosing, screening, and managing lung cancer patients have improved. This is due to our growing understanding of the biology of lung cancer. It is now possible to further deifne lung cancer types beyond small cell lung carcinoma and non-small cell lung carcinoma. Moreover, new histology-based therapeutic modalities have been developed, and more new lung cancer biomarkers have been uncovered. Therefore, more detailed histological characterization of lung cancer samples is warranted in order to determine the best course of treatment for speciifc patients. This review article describes how these new molecular technologies are shaping the way lung cancer can be treated in future.

    Surface electrical and electromagnetic geophysical methods can map enhanced electrical conductivity caused by acid mine drainage in mine tailings piles. In this case study, we investigate quantitative relationships between geophysical responses and the electrical conductivity, acidity and salinity of tailing samples at the Central Manitoba Mine tailings in Manitoba, Canada. Previous electromagnetic surveys at the site identified zones of enhanced conductivity that were hypothesized to be caused by acid mine drainage. In the present study, high-resolution EM31 and DC-resistivity measurements were made on a profile through a zone of enhanced conductivity and laboratory measurements of salinity and pH were made on saturation paste extracts from an array of tailing samples collected from the upper 2 m of tailings along the profile. Observed spatial correlation of pH and pore-fluid salinity in the tailings samples confirms that the enhanced conductivity in the Central Manitoba Mine tailings is due to acid mine drainage. Contoured cross-sections of the data indicate that the acid mine drainage is concentrated near the base of the oxidized zone in the thicker parts of the tailings pile. The zone of increased acidity extends to the surface on sloping margins causing an increase in apparent conductivity in shallow penetrating geophysical responses. The quantitative relationship between measured pH and salinity shows that the conductivity increase associated with the acid mine drainage is due only in part to conduction by ions produced from dissociation of sulfuric acid. Comparison of the observations with fluid conductivity estimates based on statistical relationships of pH and ion concentrations in water samples from across the tailings pile shows that Ca2 + and Mg2 + ions also make significant contributions to the conductivity at all values of pH and Cu2 +, Al3 + and Fe3 + ions make additional contributions at low pH. Variability in the measured conductivity at constant

    It is estimated that half of all patients with cancereventually develop a syndrome of cachexia, with anorexiaand a progressive loss of adipose tissue and skeletalmuscle mass. Cancer cachexia is characterized by systemicinflammation, negative protein and energy balance, andan involuntary loss of lean body mass. It is an insidioussyndrome that not only has a dramatic impact on patientquality of life, but also is associated with poor responsesto chemotherapy and decreased survival. Cachexia isstill largely an underestimated and untreated condition,despite the fact that multiple mechanisms are reported tobe involved in its development, with a number of cytokinespostulated to play a role in the etiology of the persistentcatabolic state. Existing therapies for cachexia, includingorexigenic appetite stimulants, focus on palliation ofsymptoms and reduction of the distress of patients andfamilies rather than prolongation of life. Recent therapiesfor the cachectic syndrome involve a multidisciplinaryapproach. Combination therapy with diet modificationand/or exercise has been added to novel pharmaceuticalagents, such as Megestrol acetate, medroxyprogesterone,ghrelin, omega-3-fatty acid among others. These agentsare reported to have improved survival rates as well asquality of life. In this review, we will discuss the emergingunderstanding of the mechanisms of cancer cachexia,the current treatment options including multidisciplinarycombination therapies, as well an update on new andongoing clinical trials.

    2003-05-01

    The survival at 5 years, of patients with ovarian cancer, has steadily improved since 1960, when surgery and alkylating agents were the only initial modalities employed to cope with the usual late presentation of the disease. In the 1980s, cisplatin and then carboplatin became established as the most active drugs, alone or in combination with other drugs. In the last decade, the antimicrotubulin drug paclitaxel, and the topoisomerase I inhibitor topotecan were noted to be active after failure of platinum drugs. These drugs, as well as others with known activity in the second-line setting, such as the pegylated liposomal doxorubicin, gemcitabine and oral etoposide, all play a role in the treatment of these patients and likely prolong survival without eradicating the disease. The plight of these patients has stimulated new areas of drug development. Here, the evolution of the current therapeutic strategy, the scientific rationale for cytotoxic and non-cytotoxic agents and their status at present are reviewed. 'Targeted' drug trials, in contrast to trials studying cytotoxic drug analogues, currently represent only a minor portion of clinical trials in ovarian cancer.

    Full Text Available Little is known about cancer treatment patterns among the elderly as depression and cancer in this older population have not been well explored. This study seeks to fill a gap in the literature by using data from the Medicare Current Beneficiary Survey from years 2000–2005 to examine depression treatment patterns among elderly diagnosed with both cancer and depression. Depression treatments examined include antidepressants with and without psychotherapy. We found that of those with both cancer and depression, 57.7% reported antidepressant use only, 19.7% received psychotherapy with or without antidepressants, and 22.6% had no depression treatment. We found those with greater comorbidity, of a minority race, with lower levels of education, and living in rural areas were less likely to receive treatment for depression. These findings highlight the need to address disparities in the treatment of depression in the elderly population with cancer.

    The current Medical Humanities Program at the University of Manitoba has evolved from a series of voluntary sessions into an integral element of the curriculum since its inception as the Human Values Program in 1986. With strong academic and financial support, the Medical Humanities Program has greatly benefited from dedicated leadership and a commitment to ongoing curricular review and redevelopment. The current Medical Humanities Program comprises six distinct components: Clinical Ethics; History of Medicine; Law; Complementary and Alternative Medicine; Palliative Care; and Human Values. Each of these components is compulsory and the first five are tested through examinations and assignments. Human Values sessions are designed to be experiential and to explore the human side of medicine as well as the intersections between medicine and the arts, literature, social psychology, and spirituality. The authors outline the origins and evolution of this successful program and describe its current components, student and faculty opinions, funding, advantages, disadvantages, and anticipated growth.

    Rectal cancer is one of the primary malignant neoplasms occurring in Mexican patients of reproductive age. Unfortunately, randomized studies in rectal cancer do not exist as they do with well-recognized colon cancer. We must individualize the epidemiology, risk factors, diagnostic approach, staging and treatment because management is different in rectal cancers affecting the mid- and lower third of the rectum than in the upper third and in colon cancers. Histological staging is the primary prognostic factor. TNM staging (tumor, node, and metastasis) is used internationally by the American Joint Committee on Cancer (AJCC). Staging is done with the assistance of endorectal ultrasound, which is best used in early-stage cancer; however, there are certain disadvantages in detecting node involvement. Magnetic resonance, on the other hand, allows for the evaluation of stenotic tumors and node involvement. Once the correct diagnosis and staging have been made, the next step is correct treatment. Neoadjuvant treatment has demonstrated to be better than adjuvant treatment. Abdominoperineal resection is rarely practiced currently, with sphincter preservation being the preferred procedure. Laparoscopic approach has conferred the advantages of the approach itself when performed by experts in the procedure but there is insufficient evidence to make it the "gold standard." Rectal cancer is a complex pathology that must be considered totally different from colon cancer for diagnosis and treatment. The patient must be staged completely and appropriately for individualizing correct treatment. More long-term studies are needed for optimizing treatment modalities.

    Three high voltage direct current (HVDC) converter stations are operated by Manitoba Hydro in conjunction with the northern generating stations on the Nelson River near Gillam, Manitoba. The Dorsey Converter Station, located approximately 900 kilometres (km) south of Gillam and 13 km northwest of Winnipeg, is an integral and critical component of Manitoba's HVDC system. The Dorsey Converter Station represents the southern terminus, where the power originating from Gillam is converted back to alternating current (AC) from DC for further distribution in southern Manitoba and for export. The current space cooling requirements for the converter station buildings are based on chiller systems scheduled to be replaced. There have been some success stories near Winnipeg with groundwater cooling, and field testing confirmed that the high permeability of the aquifer would be an asset for groundwater based cooling. The system which has been selected for installation, includes 5 pumping wells and 10 recharge wells to handle the total cooling load. Thermal interference between wells is expected to be such that winter thermal balancing would be required for sustainability, as demonstrated in digital simulations of aquifer heat transport. The assessment program and the major design considerations for this system were presented in this paper. 10 refs., 1 tab., 10 figs.

    Genetic and environmental factors are important determinants of disease distribution. Several disorders associated with ataxia are known to occur more commonly in certain ethnic groups; for example, the disequilibrium syndrome in the Hutterites. The aim of this study was to determine the ethnic and geographic distribution of pediatric patients with chronic ataxia in Manitoba, Canada. We identified 184 patients less than 17 years-of-age with chronic ataxia during 1991-2008 from multiple sources. Their diagnosis, ethnicity and place of residence were determined following a chart review. Most patients resided in Manitoba (N=177) and the majority in Winnipeg, the provincial capital. Thirty five Aboriginal, 29 Mennonite and 11 Hutterite patients resided in Manitoba. The latter two groups were significantly overrepresented in our cohort. Ataxia telangiectasia, mitochondrial disorders, and non-progressive ataxia of unknown etiology associated with pyramidal tracts signs and developmental delay were significantly more common in Mennonite patients. Four of five patients with neuronal migration disorders associated with chronic ataxia were Aboriginal. Few isolated disorders with chronic ataxia occurred in the 11 Hutterite patients including a Joubert syndrome related disorder. Three disorders associated with chronic ataxia were more prevalent than expected in Mennonites in Manitoba. Few rare disorders were more prevalent in the Hutterite and Aboriginal population. Further research is needed to determine the risk factors underlying these variations in prevalence within different ethnic groups. The unique risk factor profiles of each ethnic group need to be considered in health promotion endeavors.

    In 2001, the Government of Manitoba initiated a strategy to pursue hydrogen as a longer-term option within its portfolio of renewable energy opportunities. A key potential hydrogen application includes all-electric vehicles; metal air cells; and biofuels. A detailed hydrogen economic development strategy was formulated for the province as a whole. In 2003, Manitoba's Hydrogen Steering Committee released the first strategy document on hydrogen prepared by any jurisdiction in Canada. The report outlined an assessment framework using broad-based working groups to cover 5 lead areas. The report listed 5 priority actions on hydrogen, to which a sixth priority action has now been added. These include hydrogen buses and refueling; a by-product hydrogen fuel cell demonstration project; the creation of the Hydrogen Centre of Expertise Inc.; an on-site hydrogen system at Manitoba Hydro's Dorsey Station; a memorandum of understanding on hydrogen development with Iceland; and, a permanent refueling station and associated support facilities. These priority actions were undertaken to help define future directions and to gain experience in opportunity areas. Since the report's release, substantial progress has been made on all 6 priority actions. Two major hydrogen bus and refueling demonstration projects have been completed, with the most recent involving the hybrid fuel cell bus. Manitoba currently has 2 major sodium chlorate plants producing significant quantities of hydrogen as a by-product. This paper provided an update on the strategic approach taken by Manitoba and discussed how hydrogen can be integrated with other renewable energy priorities. 10 refs., 1 tab., 10 figs.

    Different treatment modalities have been proposed in the treatment of early gastric cancer(EGC). Endoscopic resection(ER) is an established treatment that allows curative treatment, in selected cases. In addition, ER allows for an accurate histological staging, which is crucial when deciding on the best treatment option for EGC. Recently, endoscopic mucosal resection(EMR) and endoscopic submucosal dissection(ESD) have become alternatives to surgery in early gastric cancer, mainly in Asian countries. Patients with "standard" criteria can be successfully treated by EMR techniques. Those who meet "expanded" criteria may benefit from treatment by ESD, reducing the need for surgery. Standardized ESD training system is imperative to promulgate effective and safe ESD technique to practices with limited expertise. Although endoscopic resection is an option in patients with EGC, surgical treatment continues to be a widespread therapeutic option worldwide. In this review we tried to point out the treatment modalities for early gastric cancer.

    Despite male breast cancer is rare in occurrence, it is a serious problem. In 2012, 130 men in Ukraine got breast cancer that constituted 0.74% from all patients with mentioned pathology detected in the course of year. Every year in Ukraine approximately 100 men die from breast cancer. Still many aspects of male breast cancer remain unstudied. It occurs since information about mentioned disease is mainly based on retrospective analysis of small groups. Treatment of men, who got breast cancer, is based on knowledge, which has been obtained in treatment of women with this pathology. This article is based on the results of analysis of 168 cases of breast cancer in men, who have been examined and treated in the period from 1956 to 2012. In paper the peculiarities of clinical manifestations of male breast cancer have been determined, the optimal volume of diagnostic procedures in men with suspicion of breast cancer has been established, the mammographic signs have been detected and the possible histological variants of disease have been determined, clinical course peculiarities of male breast cancer have been defined, the most essential factors of prognosis of the disease have been fixed. Furthermore, in article optimal volume of surgical treatment of male breast cancer has been substantiated, the role and place of radiotherapy in treatment of this pathology has been determined. It has been proved that adjuvant polychemotherapy should be applied to the patients with male breast cancer independently from stage of process. Also optimal schemes of this kind of treatment have been determined. The efficacy of hormonal therapy with antiestrogen in patients with positive receptors of steroid hormones and at presence of unfavorable prognostic factors of disease has been demonstrated. The inefficiency of orchiectomy as one of the widespread kinds of hormonal therapy of male breast cancer has been defined.

    Because the conflicting data currently available from the performed randomized trials it is very difficult to provide strict guidelines for the treatment of patients with locoregional advanced esophageal cancers. Surgery however, remains the standard of care for potentially resectable disease. Preoperative chemotherapy is still controversial with two large randomized trials resulting in two different conclusions regarding the survival benefit. Preoperative chemoradiation is also controversial since only one randomized trial showed a clear survival benefit however, the patients treated with surgery alone in this trial had an unusually poor outcome. And the study by Urba et al was not powered enough to show a clear survival benefit for patients treated with neoadjuvant chemoradiation. The results of three metaanalysis of these randomized studies show lower rate of resection, higher rate of R0-resection, more often postoperative mortality and better prognosis for patients with neoadjuvant radiochemotherapy. As a consequence one may consider offering neoadjuvant chemotherapy or neoadjuvant radiochemotherapy to patients with locallyadvanced disease under the premise that patients have a good performance status and understand the controversies about this therapeutic option. Larger trials with sufficient power to clearly detect survival benefits for patients treated with neoadjuvant chemotherapy or radiochemotherapy are necessary before this therapeutic option will be the standard of care.

    Much progress has been made in the treatment of lung cancer in the last ten years (adjuvant chemotherapy, targeted therapy, individualized therapy). Nonetheless, lung cancer is still the leading cause of death due to cancer and thus remains a major medical, scientific, and social problem. This review is based on national and international recommendations and selected articles from the literature. Cigarette smoking is the major pathogenic factor for lung cancer. Lung cancer can be divided into two major types that differ in their biological behavior, small cell lung cancer and non-small cell lung cancer. Whenever possible, the diagnosis should be confirmed by biopsy, the extent of disease should be documented in detail (international TNM classification/staging), and the patient's functional level should be assessed with a view toward treatment planning. Surgery for non-small cell lung cancer with curative intent is possible up to stage IIIA, while stage IIIB is the domain of radiotherapy. Surgery for small cell lung cancer with curative intent is possible for rare cases in early stages (T1N0 and T2N0, i.e., stage IA and IB). As long as small cell lung cancer is restricted to one side of the chest, simultaneous radiation therapy and chemotherapy are indicated. If a malignant pleural effusion or distant metastases are present, both lung cancers are treated palliatively with platinum-based chemotherapy.

    Breast cancer is the most common female cancer and globally remains a major public health concern. The diagnosis and treatment of breast cancer continues to develop. Diagnosis is now more precise, surgery is less mutilating and women now have the option of breast conserving therapy with better cosmesis, and without sacrificing survival. Radiotherapy is more targeted and the selection of patients for adjuvant chemotherapy is based not only on prognostic and predictive factors, but also on newer molecular profiling that will ensure that chemotherapy is given to the patients who need and respond to it. These developments all provide a more tailored approach to the treatment of breast cancer. Management now involves a multidisciplinary team approach in order to provide the highest standard of care for patients throughout their cancer journey from diagnosis through treatment and into follow-up care.

    2011-01-01

    Selenium (Se) is an essential dietary component for all animals, including human beings, that is regarded as a protective agent against cancer. Although the mode of its anticancer action is not yet fully understood, several mechanisms, such as antioxidant protection through selenoenzymes, stimulation of DNA repair, and apoptosis in tumor prestages have all been proposed. Despite the unsupported results of the last "SELECT" trial, the cancer-preventing activity of Se has been demonstrated in a majority of epidemiological studies. Moreover, recent studies suggest that Se has a potential to be used not only in cancer prevention but also in cancer treatment, where in combination with other anticancer drugs or radiation it may increase the efficacy of cancer therapy. In combating cancer cells, Se acts as a prooxidant rather than an antioxidant, inducing apoptosis through the generation of oxidative stress. Thus, inorganic Se compounds, having high redox potency, represent a promising option in cancer therapy.

    The importance of evaluating physical cues in cancer research is gradually being realized. Assessment of cancer cell physical appearance, or phenotype, may provide information on changes in cellular behavior, including migratory or communicative changes. These characteristics are intrinsically different between malignant and non-malignant cells and change in response to therapy or in the progression of the disease. Here, we report that pancreatic cancer cell phenotype was altered in response to a physical method for cancer therapy, a non-invasive radiofrequency (RF) treatment, which is currently being developed for human trials. We provide a battery of tests to explore these phenotype characteristics. Our data show that cell topography, morphology, motility, adhesion and division change as a result of the treatment. These may have consequences for tissue architecture, for diffusion of anti-cancer therapeutics and cancer cell susceptibility within the tumor. Clear phenotypical differences were observed between cancerous and normal cells in both their untreated states and in their response to RF therapy. We also report, for the first time, a transfer of microsized particles through tunneling nanotubes, which were produced by cancer cells in response to RF therapy. Additionally, we provide evidence that various sub-populations of cancer cells heterogeneously respond to RF treatment.

    Lung cancer remains the leading cause of cancer mortality in men and women in the U.S. and worldwide. About 90% of lung cancer cases are caused by smoking and the use of tobacco products. However, other factors such as radon gas, asbestos, air pollution exposures, and chronic infections can contribute to lung carcinogenesis. In addition, multiple inherited and acquired mechanisms of susceptibility to lung cancer have been proposed. Lung cancer is divided into two broad histologic classes, which grow and spread differently: small-cell lung carcinomas (SCLCs) and non-small cell lung carcinomas (NSCLCs). Treatment options for lung cancer include surgery, radiation therapy, chemotherapy, and targeted therapy. Therapeutic-modalities recommendations depend on several factors, including the type and stage of cancer. Despite the improvements in diagnosis and therapy made during the past 25 years, the prognosis for patients with lung cancer is still unsatisfactory. The responses to current standard therapies are poor except for the most localized cancers. However, a better understanding of the biology pertinent to these challenging malignancies, might lead to the development of more efficacious and perhaps more specific drugs. The purpose of this review is to summarize the recent developments in lung cancer biology and its therapeutic strategies, and discuss the latest treatment advances including therapies currently under clinical investigation.

    The efficacy of directly killing tumors by conventional cancer therapies, such as chemotherapy and radiotherapy, has been for several decades well established. But, a suppressed immune response might become a lethal side effect after repeated cycles of intensive treatment. Recently, achievements in immune checkpoint inhibitors and adoptive T cell-mediated immunotherapies have resulted in changes in frontline management of advanced cancer diseases. However, accumulated evidence indicates that immunotherapeutic and conventional strategies alone are often ineffective to eradicate big tumors or metastasis. To improve the outcomes of treatment for advanced cancer diseases, the combination of conventional cancer treatment with various immunotherapeutic approaches has been attempted and has shown potential synergistic effects. Recent studies have unexpectedly demonstrated that some strategies of conventional cancer treatment can regulate the immune response positively, thus the understanding of how to adapt conventional treatment for immunotherapy is crucial to the design of effective combination therapy of conventional treatment with immunotherapy. Here, we review both experimental and clinical studies on the therapeutic effect and its mechanisms of combining conventional therapy with immunotherapy in treatment of cancer.

Although surgery and chemoradiotherapy can cure 80%–95% of women with early stage cancer, the recurrent and metastatic disease remains a major cause of cancer death. Many efforts have been made to design new drugs and develop gene therapies to treat cervical cancer. In recent decades, research on treatment strategies has proposed several options, including the role of HPV E6 and E7 oncogenes, which are retained and expressed in most cervical cancers and whose respective oncoproteins are critical to the induction and maintenance of the malignant phenotype. Other efforts have been focused on antitumor immunotherapy strategies. It is known that during the development of cervical cancer, a cascade of abnormal events is induced, including disruption of cellular cycle control, perturbation of antitumor immune response, alteration of gene expression, and deregulation of microRNA expression. Thus, in this review article we discuss potential targets for the treatment of cervical cancer associated with HPV infection, with special attention to immunotherapy approaches, clinical trials, siRNA molecules, and their implications as gene therapy strategies against cervical cancer development.Keywords: Cervical cancer, clinical trials, gene therapy, HPV E6 and E7 oncogenes, siRNAs

    Full Text Available Total mesorectal excision is the “golden standard” of surgical treatment for rectal cancer. Development of endoscopic technologies allowed to implement the benefits of minimally invasive surgery in early rectal cancer treatment, decrease morbidity and mortality, improve functional outcome and quality of life. Oncological safety of this method is still a subject for discussion due to lack of lymph node harvest. Endoscopic operations for early rectal cancer are being actively implemented in daily practice, but lack of experience does not allow to include this method in national clinical prac-tice guidelines.

    2008-02-01

    Discussions of pediatric nutrition and cancer usually focus on important issues of ensuring an adequate nutrient intake (enteral and parenteral) during and after the early treatment phase of care. However, information is available that suggests that vitamin status may have additional roles in the care of children with cancer. Over the last decade, investigators have reported findings that suggest that maternal preconception and perinatal vitamin intake and status influence the cancer risk of the infant and child. Others have shown a relationship between vitamin and antioxidant status and the prevalence and severity of adverse side effects for children undergoing chemotherapy. Vitamin D has potential anti-cancer activity and vitamin D status is suboptimal in many children in North America. Each of these issues is briefly presented from a perspective of prevention and treatment of childhood cancer.

    Full Text Available Christina M Dieli-Conwright, Breanna Z Orozco Division of Biokinesiology and Physical Therapy, Women's Health and Exercise Laboratory, University of Southern California, Los Angeles, CA, USA Abstract: Over the past 2 decades, great strides have been made in the field of exercise-oncology research, particularly with breast cancer. This area of research is particularly important since there are >2.8 million breast cancer survivors who are in need of an intervention that can offset treatment-related side effects. Noticeable reductions in physical fitness (ie, cardiopulmonary fitness and muscular strength, negative changes in body composition (ie, increase in body mass, decrease in lean body mass, and increase in fat mass, increased fatigue, depression, or anxiety are some of the common side effects of cancer treatments that negatively impact overall quality of life and increase the risk for the development of comorbidities. Exercise plays a vital role in improving cardiopulmonary function, psychological events, muscular strength, and endurance in breast cancer survivors, and thus should be considered as a key factor of lifestyle intervention to reverse negative treatment-related side effects. The purpose of this review is to address current perspectives on the benefits of aerobic and resistance exercise after breast cancer treatments. This review is focused on the well-established benefits of exercise on physical and emotional well-being, bone health, lymphedema management, and the postulated benefits of exercise on risk reduction for recurrence of breast cancer.

  19. Fenretinide: a novel treatment for endometrial cancer.

    Directory of Open Access Journals (Sweden)

    Navdha Mittal

    Full Text Available Resistance to progestin treatment is a major hurdle in the treatment of advanced and reoccurring endometrial cancer. Fenretinide is a synthetic retinoid that has been evaluated in clinical trials as a cancer therapeutic and chemo-preventive agent. Fenretinide has been established to be cytotoxic to many kinds of cancer cells. In the present study, we demonstrate that fenretinide decreased cell viability and induced apoptosis in Ishikawa cells, which are an endometrial cancer cell line, in dose dependent manner in-vitro. This effect was found to be independent of retinoic acid nuclear receptor signaling pathway. Further, we have shown that this induction of apoptosis by fenretinide may be caused by increased retinol uptake via STRA6. Silencing of STRA6 was shown to decrease apoptosis which was inhibited by knockdown of STRA6 expression in Ishikawa cells. Results of an in-vivo study demonstrated that intraperitoneal injections of fenretinide in endometrial cancer tumors (created using Ishikawa cells in mice inhibited tumor growth effectively. Immunohistochemistry of mice tumors showed a decrease in Ki67 expression and an increase in cleaved caspase-3 staining after fenretinide treatment when compared to vehicle treated mice. Collectively, our results are the first to establish the efficacy of fenretinide as an antitumor agent for endometrial cancer both in-vitro and in-vivo, providing a valuable rationale for initiating more preclinical studies and clinical trials using fenretinide for the treatment of endometrial cancer.

    Spices have been widely used as food flavorings and folk medicines for thousands of years. Numerous studies have documented the antioxidant, anti-inflammatory and immunomodulatory effects of spices, which might be related to prevention and treatment of several cancers, including lung, liver, breast, stomach, colorectum, cervix, and prostate cancers. Several spices are potential sources for prevention and treatment of cancers, such as Curcuma longa (tumeric), Nigella sativa (black cumin), Zingiber officinale (ginger), Allium sativum (garlic), Crocus sativus (saffron), Piper nigrum (black pepper) and Capsicum annum (chili pepper), which contained several important bioactive compounds, such as curcumin, thymoquinone, piperine and capsaicin. The main mechanisms of action include inducing apoptosis, inhibiting proliferation, migration and invasion of tumors, and sensitizing tumors to radiotherapy and chemotherapy. This review summarized recent studies on some spices for prevention and treatment of cancers, and special attention was paid to bioactive components and mechanisms of action.

  5. How useful are unconventional cancer treatments?

    1999-10-01

    Unconventional cancer treatments are used frequently. Therefore, oncologists need to know about them. This article gives an overview of current knowledge on the most prevalent complementary or alternative cancer therapies. A distinction is made between alleged cures, preventive and adjunctive measures. Shark cartilage, mistletoe, thymus therapy, essiac, hydrazine sulphate, 714-X, dietary regimens, green tea and Panax ginseng are all covered specifically. None of these treatments offer reasonable hope for a cure. Some strategies are promising in terms of cancer prevention. The true potential of unconventional therapies might lie in adjunctive and palliative care. It is concluded that good evidence in this area is scarce. Vis-à-vis the high prevalence of unconventional cancer treatments, rigorous investigations are mandatory, not least for increasing the safety of future patients.

    Analysis of regional variations in use of prenatal care to identify individual-level and neighbourhood-level determinants of inadequate prenatal care among women giving birth in the province of Manitoba. Data were obtained from Manitoba Health administrative databases and the 1996 Canadian Census. An index of prenatal care use was calculated for each singleton live birth from 1991 to 2000 (N = 149,291). Births were geocoded into 498 geographic districts, and a spatial analysis was conducted, consisting of data visualization, spatial clustering, and data modelling using Poisson regression. We found wide variation in rates of inadequate prenatal care across geographic areas, ranging from 1.1% to 21.5%. Higher rates of inadequate care were found in the inner-city of Winnipeg and in northern Manitoba. After adjusting for individual characteristics, the highest rates of inadequate prenatal care were among women living in neighbourhoods with the lowest average family income, the highest proportion of the population who were unemployed, the highest rates of recent immigrants, the highest percentage of the population reporting Aboriginal status, the highest percentage of single parent families, the highest percentage of the population with fewer than nine years of education, and the highest rates of women who smoked during pregnancy. Social inequalities exist in the use of prenatal care among Manitoba women, despite there being a universally funded health care system. Regional disparities in rates of inadequate prenatal care emphasize the need for further research to determine specific risk factors for inadequate prenatal care in socioeconomically disadvantaged neighbourhoods, followed by provision of effective targeted services.

    Since extrahepatic bile duct cancer is difficult to diagnose and to cure, a safe and radical surgical strategy is needed. In this review, the modes of infiltration and spread of extrahepatic bile duct cancer and surgical strategy are discussed. Extended hemihepatectomy, with or without pancreatoduodenectomy (PD), plus extrahepatic bile duct resection and regional lymphadenectomy has recently been recognized as the standard curative treatment for hilar bile duct cancer. On the other hand, PD is the choice of treatment for middle and distal bile duct cancer. Major hepatectomy concomitant with PD (hepatopancreatoduodenectomy) has been applied to selected patients with widespread tumors. Preoperative biliary drainage (BD) followed by portal vein embolization (PVE) enables major hepatectomy in patients with hilar bile duct cancer without mortality. BD should be performed considering the surgical procedure, especially, in patients with separated intrahepatic bile ducts caused by hilar bile duct cancer. Right or left trisectoriectomy are indicated according to the tumor spread and biliary anatomy. As a result, extended radical resection offers a chance for cure of hilar bile duct cancer with improved resectability, curability, and a 5-year survival rate of 40%. A 5-year survival rate has ranged from 24% to 39% after PD for middle and distal bile duct cancer.

    2016-01-01

    Lung cancer is the second most common cancer and the primary cause of cancer-related death in both men and women in the United States and rest of the world. Due to diagnosis at an advanced stage, it is associated with a high mortality in a majority of patients. In recent years, enormous advances have occurred in the development and application of nanotechnology in the detection, diagnosis, and therapy of cancer. This progress has led to the development of the emerging field of "cancer nanomedicine." Nanoparticle-based therapeutic systems have gained immense popularity due to their bioavailability, in vivo stability, intestinal absorption, solubility, sustained and targeted delivery, and therapeutic effectiveness of several anticancer agents. Currently, a plethora of nanocarrier formulations are utilized including lipid-based, polymeric and branched polymeric, metal-based, magnetic, and mesoporous silica. In lung cancer, nanoparticle-based therapeutics is paving the way in the diagnosis, imaging, screening, and treatment of primary and metastatic tumors. The application and expansion of novel nanocarriers for drug delivery is an exciting and challenging research filed, in particular for the delivery of emerging cancer therapies. Some of the current progress and challenges in nanoparticle-based drug delivery systems for lung cancer treatment are discussed.

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    Multidisciplinary approach for rectal cancer treatment is currently well defined. Nevertheless, new and promising advances are enriching the portrait. Since the US NIH Consensus in the early 90's some new characters have been added. A bird's-eye view along the last decade shows the main milestones in the development of rectal cancer treatment protocols. New drugs, in combination with radiotherapy are being tested to increase response and tumor control outcomes. However, therapeutic intensity is often associated with toxicity. Thus, innovative strategies are needed to create a better-balanced therapeutic ratio. Molecular targeted therapies and improved technology for delivering radiotherapy respond to the need for accuracy and precision in rectal cancer treatment.

  1. Oncolytic Adenoviruses in Cancer Treatment

    Directory of Open Access Journals (Sweden)

    Ramon Alemany

    2014-02-01

    Full Text Available The therapeutic use of viruses against cancer has been revived during the last two decades. Oncolytic viruses replicate and spread inside tumors, amplifying their cytotoxicity and simultaneously reversing the tumor immune suppression. Among different viruses, recombinant adenoviruses designed to replicate selectively in tumor cells have been clinically tested by intratumoral or systemic administration. Limited efficacy has been associated to poor tumor targeting, intratumoral spread, and virocentric immune responses. A deeper understanding of these three barriers will be required to design more effective oncolytic adenoviruses that, alone or combined with chemotherapy or immunotherapy, may become tools for oncologists.

    Colorectal cancer has a high incidence, and approxi-mately 60% of colorectal cancer patients are older than 70, with this incidence likely increasing in the near future. Elderly patients(> 70-75 years of age) are a very heterogeneous group, ranging from the very fit to the very frail. Traditionally, these patients have often been under-treated and recruited less frequently to clinical trials than younger patients, and thus are underrepresented in publications about cancer treatment. Recent studies suggest that fit elderly patients can be treated in the same way as their younger counterparts, but the treatment of frail patients with comorbidities is still a matter of controversy. Many factors should be taken into account, including fitness for treatment, the wishes of the patient and family, and quality of life. This review will focus on the existing evidence for surgical, oncologic, and palliative treatment in patients over 70 years old with colorectal cancer. Careful patient assessment is necessary in order to individualize treatment approach, and this should rely on a multidisciplinary process. More well-designed controlled trials are needed in this patient population.

    Full Text Available Introduction: Although indoor tanning causes cancer, it remains relatively common among adolescents. Little is known about indoor tanning prevalence and habits in Canada, and even less about associated behaviours. This study explores the prevalence of adolescent indoor tanning in Manitoba and its association with other demographic characteristics and health behaviours. Methods: We conducted secondary analyses of the 2012/13 Manitoba Youth Health Survey data collected from Grade 7 to 12 students (n = 64 174 and examined associations between indoor tanning (whether participants had ever used artificial tanning equipment and 25 variables. Variables with statistically significant associations to indoor tanning were tested for collinearity and grouped based on strong associations. For each group of highly associated variables, the variable with the greatest effect upon indoor tanning was placed into the final logistic regression model. Separate analyses were conducted for males and females to better understand sex-based differences, and analyses were adjusted for age. Results: Overall, 4% of male and 9% of female students reported indoor tanning, and prevalence increased with age. Relationships between indoor tanning and other variables were similar for male and female students. Binary logistic regression models indicated that several variables significantly predicted indoor tanning, including having part-time work, being physically active, engaging in various risk behaviours such as driving after drinking for males and unplanned sex after alcohol/drugs for females, experiencing someone say something bad about one's body shape/size/appearance, identifying as trans or with another gender, consuming creatine/other supplements and, for females only, never/rarely using sun protection. Conclusion: Indoor tanning among adolescents was associated with age, part-time work, physical activity and many consumption behaviours and lifestyle risk factors. Though

    Geology and reservoir characteristics of Manitoba`s producing horizons were described, and recent activity in exploration and development prospects for the immediate future were reviewed. These prospects have improved considerably, thanks to recent efforts of the Manitoba Department of Energy and Mines to ensure that barriers to petroleum investment are eliminated. As a result of these and related efforts by the Manitoba government the investment climate is stable and competitive. Advantages in Manitoba include availability of Crown land at comparatively low prices, drilling and exploration incentives, low drilling and completion costs, and easy access to markets. Development drilling opportunities exist for each of Manitoba`s five producing formations (the sandstones of the Jurassic Melita and Amaranth formations, and the Mississippian Bakken Formation, and the carbonates of the Mississipian Lodgepole and Mission Canyon formations). Sample economic scenarios run on three development scenarios and modelled after typical Manitoba oil play were very favorable, indicating a potential rate of return on investments of 25 to 37 per cent and pay-out in 2.6 to 3.2 years. 10 refs., 7 tabs., 5 figs.

    Full Text Available Non-small cell lung cancer (NSCLC is one of the deadliest cancers worldwide. In search for new NSCLC treatment options, we screened a cationic amphiphilic drug (CAD library for cytotoxicity against NSCLC cells and identified several CAD antihistamines as inducers of lysosomal cell death. We then performed a cohort study on the effect of CAD antihistamine use on mortality of patients diagnosed with non-localized cancer in Denmark between 1995 and 2011. The use of the most commonly prescribed CAD antihistamine, loratadine, was associated with significantly reduced all-cause mortality among patients with non-localized NSCLC or any non-localized cancer when compared with use of non-CAD antihistamines and adjusted for potential confounders. Of the less frequently described CAD antihistamines, astemizole showed a similar significant association with reduced mortality as loratadine among patients with any non-localized cancer, and ebastine use showed a similar tendency. The association between CAD antihistamine use and reduced mortality was stronger among patients with records of concurrent chemotherapy than among those without such records. In line with this, sub-micromolar concentrations of loratadine, astemizole and ebastine sensitized NSCLC cells to chemotherapy and reverted multidrug resistance in NSCLC, breast and prostate cancer cells. Thus, CAD antihistamines may improve the efficacy of cancer chemotherapy.

    The introduction of cisplatin in cancer treatment represents an important achievement in the oncologic field. Many types of cancers are now treated with this drug, and in testicular cancer patients major results are reached. Since 1965, other compounds were disovered and among them carboplatin and oxaliplatin are the main Cisplatin analogues showing similar clinical efficacy with a safer toxicity profile. Lipoplatin is a new liposomal cisplatin formulation which seems to have these characteristics. Lipoplatin was shown to be effective in NSCLC both in phase 2 and phase 3 trials, with the same response rate of Cisplatin, a comparable overall survival but less toxicity. A new protocol aiming to elucidate the double capacity of Lipoplatin to act as a chemotherapeutic and angiogenetic agent in triple-negative breast cancer patients is upcoming.

    In the late 1960s, the steroidal alkaloid cyclopamine was isolated from the plant Veratrum californicum and identified as the teratogen responsible for craniofacial birth defects including cyclops in the offspring of sheep grazing on mountain ranges in the western United States. Cyclopamine was found to inhibit the hedgehog (Hh) signaling pathway, which plays a critical role in embryonic development. More recently, aberrant Hh signaling has been implicated in several types of cancer. Thus, inhibitors of the Hh signaling pathway, including cyclopamine derivatives, have been targeted as potential treatments for certain cancers and other diseases associated with the Hh signaling pathway. A brief history of cyclopamine and cyclopamine derivatives investigated for the treatment of cancer is presented.

    Full Text Available Introduction. A locally advanced prostate cancer is defined as a malignant process spreading beyond the prostate capsule or in seminal vesicles but without distant metastasis or regional lymph nodes invasion. Clinical classification, prediction and treatment of prostate cancer. An exact staging of clinical T3 stadium is usually difficult because of the frequent over and under staging. The risk prognostic stratification is performed through nomograms and ANN (artificial neural networks. The options for treatment are: radical prostatectomy, external radiotherapy and interstitial implantation of radioisotopes, hormonal therapy by androgen blockade. Radical prostatectomy is considered in patients with T3 stage but extensive dissection of lymph nodes, dissection of neurovascular bundle (on tumor side, total removal of seminal vesicle and sometimes resection of bladder neck are obligatory. Postoperative radiotherapy is performed in patients with invasion of seminal vesicles and capsular penetration or with prostate specific antigen value over 0.1 ng/ml, one month after the surgical treatment. Definitive radiotherapy could be used as the best treatment option considering clinical stage, Gleason score, age, starting prostate specific antigen (PSA value, concomitant diseases, life expectancy, quality of life, through multidisciplinary approach (combined with androgen deprivation. Hormonal therapy in intended for patients who are not eligible for surgical treatment or radiotherapy. Conclusion. Management of locally advanced prostate cancer is still controversial and studies for better diagnosis and new treatment modalities are ongoing.

    Pancreatic adenocarcinoma is one of the most aggressive human malignancies,ranking 4th among causes for cancer-related death in the Western world including the United States.Surgical resection offers the only chance of cure,but only 15 to 20 percent of cases are potentially resectable at presentation.Different studies demonstrate and confirm that advanced pancreatic cancer is among the most complex cancers to treat and that these tumors are relatively resistant to chemotherapy and radiotherapy.Currently there is no consensus around the world on what constitutes "standard"adjuvant therapy for pancreatic cancer.This controversy derives from several studies,each fraught with its own limitations.Standards of care also vary somewhat with regard to geography and economy,for instance chemo-radiotherapy followed by chemotherapy or vice versa is considered the optimal therapy in North America while chemotherapy alone is the current standard in Europe.Regardless of the efforts in adjuvant and neoadjuvant improved therapy,the major goal to combat pancreatic cancer is to find diagnostic markers,identifying the disease in a pre-metastatic stage and making a curative treatment accessible to more patients.In this review,authors examined the different therapy options for advanced pancreatic patients in recent years and the future directions in adjuvant and neoadjuvant treatments for these patients.

    Although pancreatic cancer is but the eleventh most prevalent cancer in the US, it is predicted that of all the patients newly diagnosed with this disease in 2014, only 27% will still be alive at the end of the first year and only 6% will make it past 5 years. The choice of chemotherapy in the treatment of pancreatic cancer is dependent on disease stage and patient performance status but, in general, the most widely used approved regimens include 5-fluorouracil (5-FU) combinations and gemcitabine combinations. Recent therapeutic strategies have resulted in an improvement in survival of patients with pancreatic cancer but the magnitude of change is disappointing and vast improvements are still needed. The goal of immunotherapy is to enhance and guide the body's immune system to recognize tumor-specific antigens and mount an attack against the disease. Among newer immune therapies, GI-4000 consists of 4 different targeted molecular immunogens, each containing a different Ras protein (antigen) encoded by the most commonly found mutant RAS genes in solid tumors—RAS mutations exist in over 90% of pancreatic ductal adenocarcinomas. We will review pancreatic cancer epidemiology and its current treatment options, and consider the prospects of immunotherapy, focusing on GI-4000. We discuss the potential mechanism of action of GI-4000, and the performance of this vaccination series thus far in early phase clinical trials. PMID:25585100

  5. Retinoids in lung cancer chemoprevention and treatment.

    1999-01-01

    In this review, we aim to synthesize the emerging picture of retinoids in lung cancer through a summary of ongoing investigations in biology, chemoprevention and therapy settings, in an attempt to clarify the possible role of these agents in such a disease. Early work in head and neck cancer has evidenced the capability of retinoids to interrupt field carcinogenesis by reversing premalignant lesions and decreasing the incidence of second primary tumors (SPTs). At this time, the completed randomized trials in lung cancer have failed to demonstrate an evident chemopreventive effect of the tested agents on different study end points, although both a marginally significant benefit of retinol palmitate in time-to-development rates for smoke-related SPTs and a potential preventive effect of retinol supplementation against mesothelioma in selected populations of asbestos-exposed workers have been recently reported. Concerning the role of retinoids in lung cancer treatment, a moderate activity of 13-cis-retinoic acid (13cRA) or all-transretinoic acid (ATRA) as single agents has been reported in small series of advanced, mostly pretreated lung cancer patients. More encouraging findings derive from combination studies, in which retinoids, especially ATRA, are added to either alpha-interferon or chemotherapy and radiotherapy. Major recent advances have been made towards the understanding of retinoids mechanisms of action; at this regard, the role of RAR-beta basal or treatment-induced levels seems to be of particular interest as intermediate end point and/or independent prognostic factor, besides their known importance in lung carcinogenesis. Future research for chemopreventive and therapeutic programs with retinoids in lung cancer should be focused on the investigation of new generation compounds with a specificity for individual retinoid nuclear receptors. Such selective molecules may have a greater activity against lung cancer, with a more favourable toxicity profile, as

    The application of nanotechnology in medicine is offering many exciting possibilities in healthcare. Engineered nanoparticles have the potential to revolutionize the diagnosis and the therapy of several diseases, particularly by targeted delivery of anticancer drugs and imaging contrast agents. Prostate cancer, the second most common cancer in men, represents one of the major epidemiological problems, especially for patients in the advanced age. There is a substantial interest in developing therapeutic options for treatment of prostate cancer based on use of nanodevices, to overcome the lack of specificity of conventional chemotherapeutic agents as well as for the early detection of precancerous and malignant lesions. Herein, we highlight on the recent development of nanotechnology strategies adopted for the management of prostate cancer. In particular, the combination of targeted and controlled-release polymer nanotechnologies has recently resulted in the clinical development of BIND-014, a promising targeted Docetaxel-loaded nanoprototype, which can be validated for use in the prostate cancer therapy. However, several limitations facing nanoparticle delivery to solid tumours, such as heterogeneity of intratumoural barriers and vasculature, cytotoxicity and/or hypersensitivity reactions to currently available cancer nanomedicines, and the difficult in developing targeted nanoparticles with optimal biophysicochemical properties, should be still addressed for a successful tumour eradication.

  7. Mechanisms and treatment of cancer cachexia.

    Science.gov (United States)

    Argilés, J M; López-Soriano, F J; Busquets, S

    2013-12-01

    According to a recent consensus, cachexia is a complex metabolic syndrome associated with underlying illness and characterised by loss of muscle with or without loss of fat mass. The prominent clinical feature of cachexia is weight loss. Cachexia occurs in the majority of terminal cancer patients and it is responsible for the deaths of 22% of cancer patients. Although body weight is, indeed, an important factor to be taken into consideration in any cachexia treatment, body composition, physical performance and quality of life should be monitored. From the results presented here, one can speculate that a single therapy may not be completely successful in the treatment of cachexia. From this point of view, treatments involving different combinations are more likely to be successful. The objectives of any therapeutical combination are two: an anticatabolic aim directed towards both fat and muscle catabolism and an anabolic objective leading to the synthesis of macromolecules such as contractile proteins.

    The Dean and Betty Gallo Prostate Cancer Center (GPCC) was established with the goal of eradicating prostate cancer and improving the lives of men at risk for the disease through research, treatment, education and prevention. GPCC was founded in the memory of Dean Gallo, a beloved New Jersey Congressman who died tragically of prostate cancer diagnosed at an advanced stage. GPCC unites a team of outstanding researchers and clinicians who are committed to high-quality basic research, translation of innovative research to the clinic, exceptional patient care, and improving public education and awareness of prostate cancer. GPCC is a center of excellence of The Cancer Institute of New Jersey, which is the only NCI-designated comprehensive cancer center in the state. GPCC efforts are now integrated well as part of our Prostate Program at CINJ, in which Dr. Robert DiPaola and Dr. Cory Abate-Shen are co-leaders. The Prostate Program unites 19 investigators from 10 academic departments who have broad and complementary expertise in prostate cancer research. The overall goal and unifying theme is to elucidate basic mechanisms of prostate growth and oncogenesis, with the ultimate goal of promoting new and effective strategies for the eradication of prostate cancer. Members' wide range of research interests collectively optimize the chances of providing new insights into normal prostate biology and unraveling the molecular pathophysiology of prostate cancer. Cell culture and powerful animal models developed by program members recapitulate the various stages of prostate cancer progression, including prostatic intraepithelial neoplasia, adenocarcinoma, androgen-independence, invasion and metastases. These models promise to further strengthen an already robust program of investigator-initiated therapeutic clinical trials, including studies adopted by national cooperative groups.

    Brain metastases are not only the most common intracranial neoplasm in adults but also very prevalent in patients with lung cancer. Patients have been grouped into different classes based on the presence of prognostic factors such as control of the primary tumor, functional performance status, age, and number of brain metastases. Patients with good prognosis may benefit from more aggressive treatment because of the potential for prolonged survival for some of them. In this review, we will comprehensively discuss the therapeutic options for treating brain metastases, which arise mostly from a lung cancer primary. In particular, we will focus on the patient selection for combined modality treatment of brain metastases, such as surgical resection or stereotactic radiosurgery (SRS) combined with whole brain irradiation; the use of radiosensitizers; and the neurocognitive deficits after whole brain irradiation with or without SRS. The benefit of prophylactic cranial irradiation (PCI) and its potentially associated neuro-toxicity for both small cell lung cancer (SCLC) and non-small cell lung cancer (NSCLC) are also discussed, along with the combined treatment of intrathoracic primary disease and solitary brain metastasis. The roles of SRS to the surgical bed, fractionated stereotactic radiotherapy, WBRT with an integrated boost to the gross brain metastases, as well as combining WBRT with epidermal growth factor receptor (EGFR) inhibitors, are explored as well.

    Structural foundations in cold climates must extend below depths of expected frost penetration to protect against frost heaving. The Radisson-Churchill transmission line is the most northern line constructed by Manitoba Hydro. The transmission line crosses areas of both discontinuous and continuous permafrost. This study focused on potential permafrost degradation in the foundations of the power transmission towers. The thermal effectiveness of the foundation design was investigated through numerical modeling of the thermal effects of climate on the transmission tower foundations. The study showed that changing ground cover affects the thermal regime and may cause permafrost degradation. This may lead to reduced bearing capacity for structures, lateral spreading of embankments, and large settlements. Manitoba Hydro successfully used synthetic foundations insulated with polystyrene geofoam for the towers in order to reduce permafrost degradation in the foundations in the warmer southern portions of the transmission line. The geofoam was also used to help prevent frost heaving in the colder northern portions. As part of the thermal monitoring program, ground temperatures were monitored from 1987-1990. Recent studies have improved the understanding of the performance of geofoam insulated foundations. The results from this study will be expanded in future studies to include effects of groundwater and settlements in the development of an elastic thermo-plastic model. 10 refs., 1 tab., 7 figs.

    Breast cancer is the most frequent cancer affecting women worldwide. In every setting, the majority of women are treated with an evergrowing arsenal of therapeutic agents that have greatly improved their outcomes. However, these therapies can also be associated with significant adverse events. Areas covered: This review aims to thoroughly describe the current state of the evidence regarding the potential cardiotoxicity of agents commonly used in the treatment of breast cancer. These include chemotherapeutic agents, anti-HER2 therapies and CDK4/6 and mTOR inhibitors. Furthermore, issues related to the risk stratification and monitoring tools are explored. Expert opinion: Anthracycline- and trastuzumab-related cardiac toxicities have been extensively studied. Substantial evidence is now available concerning additional anti-HER2 agents such as pertuzumab, T-DM1 and tyrosine kinase inhibitors; overall, the cardiotoxicity profile is reassuring. Cardiac events due to endocrine therapy are mostly ischemic and, in the context of prolonged therapy, need specific attention. Novel agents implicated in the treatment of hormone receptor-positive disease are potentially arrhythmogenic and the exact risk will need to be further refined. As for today, assessment of baseline risk factors prior to treatment initiation and cardiac imaging before and during treatment remains the optimal way to prevent cardiac dysfunction. Cardioprotective therapy in primary prevention is still a matter of debate.

Chronic treatment requires continuous access to facilities that provide cancer care, with considerable effort, particularly economic, on the part of patients and caregivers. Oral chemotherapy could be limited as a consequence of poor compliance and adherence, especially by elderly patients.Methods: We selected 30 cancer patients referred to our department and treated with oral therapy (capecitabine, vinorelbine, imatinib, sunitinib, sorafenib, temozolomide, ibandronate. This pilot study of oral therapy in the patient’s home was undertaken by a doctor and two nurses with experience in clinical oncology. The instruments used were clinical diaries recording home visits, hospital visits, need for caregiver support, and a questionnaire specially developed by the European Organization for Research and Treatment of Cancer (EORTC, known as the QLQ-C30 version 2.0, concerning the acceptability of oral treatment from the patient’s perspective.Results: This program decreased the need to access cancer facilities by 98.1%, promoted better quality of life for patients, as reflected in increased EORTC QLQ-C30 scores over time, allowing for greater adherence to oral treatment as a result of control of drug administration outside the hospital. This model has allowed treatment of patients with difficult access to care (elderly, disabled or otherwise needed caregivers that in the project represent the majority (78% of these.Conclusions: This model of active home care improves quality of life and adherence with oral therapy, reduces the need to visit the hospital, and consequently decreases the number of lost hours of work on

  20. Theophylline in the Treatment of Cancer

    Full Text Available Theophylline is a drug used for the treatment of obstructive airway diseases. It inhibits the enzyme phosphodiesterase, thereby preventing the intracellular break-down of cyclic AMP. Potentially beneficial therapeutic effects of theophylline include bronchial smooth-muscle relaxation, enhanced mucociliary transport, decrease in pulmonary hypertension, improved diaphragmatic contractility, and central stimulation of ventilation. On the other hand, theophylline evokes a concentration- and time-dependent decrease in DNA synthesis in human breast cancer cells. Theophylline-treated melanoma cells exhibit low adhesion to laminin/collagen type IV. Consequently, theophylline possesses the capacity to inhibit not only cell proliferation, but also the metastatic behaviour of melanoma cells. This drug prevents neovascularization of the tumor by blocking endothelial cell proliferation. The combination of theophylline with cytotoxic drugs may permit a reduction in the effective dose needed in chemotherapy treatment of lung cancer patients. It has also a prophylactic effect on the nephrotoxicity due to cisplatin. However, this drug may inhibit small cell lung cancer cells but stimulate pulmonary adenocarcinoma cells. It is necessary to perform large, prospective studies for the exact role of theophylline on each type of lung cancer.

  1. Treatment of Pancreatic Cancer with Pharmacological Ascorbate.

    2015-01-01

    The prognosis for patients diagnosed with pancreatic cancer remains dismal, with less than 3% survival at 5 years. Recent studies have demonstrated that high-dose, intravenous pharmacological ascorbate (ascorbic acid, vitamin C) induces cytotoxicity and oxidative stress selectively in pancreatic cancer cells vs. normal cells, suggesting a promising new role of ascorbate as a therapeutic agent. At physiologic concentrations, ascorbate functions as a reducing agent and antioxidant. However, when pharmacological ascorbate is given intravenously, it is possible to achieve millimolar plasma concentration. At these pharmacological levels, and in the presence of catalytic metal ions, ascorbate can induce oxidative stress through the generation of hydrogen peroxide (H2O2). Recent in vitro and in vivo studies have demonstrated ascorbate oxidation occurs extracellularly, generating H2O2 flux into cells resulting in oxidative stress. Pharmacologic ascorbate also inhibits the growth of pancreatic tumor xenografts and displays synergistic cytotoxic effects when combined with gemcitabine in pancreatic cancer. Phase I trials of pharmacological ascorbate in pancreatic cancer patients have demonstrated safety and potential efficacy. In this chapter, we will review the mechanism of ascorbate-induced cytotoxicity, examine the use of pharmacological ascorbate in treatment and assess the current data supporting its potential as an adjuvant in pancreatic cancer.

    A total of 1165 patients with stomach cancer were entered into a prospective, observational national study. They represented 54 per cent of all stomach cancer patients reported to the Cancer Registry in Norway during the study period, and data are analysed for three hospital levels (local, county and university hospitals). The median age was 71 years (range 18-96 years). The median pretreatment delay was 113 days, and 46 per cent of patients had a performance status (Karnofsky index) of less than or equal to 80. The diagnosis was confirmed by pre-operative histology in 88 per cent of cases. In all, 88 per cent of patients underwent surgery, the resectability rate was 67 per cent and 50 per cent had a potential curative operation. Total gastrectomy was most commonly performed. Lymph node dissection was performed in 14 per cent of those undergoing a curative resection. The postoperative complication rate was 27 per cent but varied with the type of operation, being highest in proximal resection (55 per cent) and lowest after distal resection (19 per cent). A total of 7 per cent of the patients died postoperatively. Most patients had advanced disease at the time of treatment and only 6 per cent had stage I tumours. There were significant differences in patient and treatment characteristics between the three hospital levels. In conclusion, patient selection bias which will influence results does occur. A fairly aggressive attitude towards local disease was found, but the low proportion of patients undergoing lymph node dissection not only leads to questions regarding the efficacy of this treatment policy, but also casts doubt on the validity of staging of stomach cancer. Morbidity and mortality rates are still high. The consequences of the differences revealed between hospital groups are difficult to interpret. Proponents of both regionalization of treatment and small hospital care may find arguments for their case in the data.

  3. Exercise training as treatment in cancer cachexia.

    2014-06-01

    Cachexia is a wasting syndrome that may accompany a plethora of diseases, including cancer, chronic obstructive pulmonary disease, aids, and rheumatoid arthritis. It is associated with central and systemic increases of pro-inflammatory factors, and with decreased quality of life, response to pharmacological treatment, and survival. At the moment, there is no single therapy able to reverse cachexia many symptoms, which include disruption of intermediary metabolism, endocrine dysfunction, compromised hypothalamic appetite control, and impaired immune function, among other. Growing evidence, nevertheless, shows that chronic exercise, employed as a tool to counteract systemic inflammation, may represent a low-cost, safe alternative for the prevention/attenuation of cancer cachexia. Despite the well-documented capacity of chronic exercise to counteract sustained disease-related inflammation, few studies address the effect of exercise training in cancer cachexia. The aim of the present review was hence to discuss the results of cachexia treatment with endurance training. As opposed to resistance exercise, endurance exercise may be performed devoid of equipment, is well tolerated by patients, and an anti-inflammatory effect may be observed even at low-intensity. The decrease in inflammatory status induced by endurance protocols is paralleled by recovery of various metabolic pathways. The mechanisms underlying the response to the treatment are considered.

    Low-dose rate brachytherapy has become a mainstream treatment option for men diagnosed with prostate cancer because of excellent long-term treatment outcomes in low-, intermediate-, and high-risk patients. Largely due to patient lead advocacy for minimally invasive treatment options, high-quality prostate implants have become widely available in the US, Europe, and Japan. The reason that brachytherapy results are reproducible in several different practice settings is because numerous implant quality factors have been defined over the last 20 years, which can be applied objectively to judge the success of the intervention both during and after the procedure. In addition, recent long-term follow-up studies have clarified that the secondary cancer incidence of brachytherapy is not clinically meaningful. In terms of future directions, the study of radiation repair genetics may allow for the counseling physician to better estimate any given patients risk for side effects, thereby substantially reducing the therapeutic uncertainties faced by patients choosing a prostate cancer intervention.

  5. Apoptosis in cancer: from pathogenesis to treatment

    2011-09-01

    Full Text Available Abstract Apoptosis is an ordered and orchestrated cellular process that occurs in physiological and pathological conditions. It is also one of the most studied topics among cell biologists. An understanding of the underlying mechanism of apoptosis is important as it plays a pivotal role in the pathogenesis of many diseases. In some, the problem is due to too much apoptosis, such as in the case of degenerative diseases while in others, too little apoptosis is the culprit. Cancer is one of the scenarios where too little apoptosis occurs, resulting in malignant cells that will not die. The mechanism of apoptosis is complex and involves many pathways. Defects can occur at any point along these pathways, leading to malignant transformation of the affected cells, tumour metastasis and resistance to anticancer drugs. Despite being the cause of problem, apoptosis plays an important role in the treatment of cancer as it is a popular target of many treatment strategies. The abundance of literature suggests that targeting apoptosis in cancer is feasible. However, many troubling questions arise with the use of new drugs or treatment strategies that are designed to enhance apoptosis and critical tests must be passed before they can be used safely in human subjects.

The present report presents an updated and final survival......, neither on progression-free nor overall survival. However, the outcomes in a subset of patients, which, after the first eight treatment cycles, received cetuximab alone, suggested a beneficial effect of cetuximab monotherapy. CONCLUSIONS: Adding cetuximab to Nordic FLOX did not provide any clinical...

    2016-04-01

    Breast cancer (BC) is the most common cancer in women worldwide, and has an undeniable negative impact on public health. The advent of molecular biology and immunotherapy has made targeted therapeutic interventions possible, providing treatments tailored to the individual characteristics of the patient and the disease. The over-expression of human epidermal growth factor receptor (HER) 2 is implicated in the pathophysiology of BC and represents a clinically relevant biomarker for its treatment. Trastuzumab, a recombinant antibody targeting HER2, was the first biological drug approved for the treatment of HER2-positive BC. Although there are currently other anti-HER2 agents available (e.g. pertuzumab and lapatinib), trastuzumab remains the gold standard for treatment of this disease subtype. Nonetheless, concerns have been raised regarding potential cardiotoxicity and treatment resistance. Moreover, several other therapeutic issues remain unclear and have been addressed in an inconsistent way. The current literature lacks a comprehensive review of trastuzumab providing useful information for clinical practice, including pharmacokinetic and pharmacodynamic aspects, its clinical use, existing controversies and future advances. This detailed review of trastuzumab in the pharmacotherapy of BC attempts to fill this gap.

The patients who responded to the conservative preoperative treatment well are more likely to survive than the patients who did not respond favourably to the conservative preoperative treatment.

  9. Personal values and cancer treatment refusal.

    2000-10-01

    This pilot study explores the reasons patients have for refusing chemotherapy, and the ways oncologists respond to them. Our hypothesis, generated from interviews with patients and oncologists, is that an ethical approach that views a refusal as an autonomous choice, in which patients are informed about the pros and cons of treatment and have to decide by weighing them, is not sufficient. A different ethical approach is needed to deal with the various evaluations that play a role in treatment refusal. If patients forgo further treatment, while curative or palliative methods are available, there is no perspective from which to integrate the weighing of pros and cons of treatment and the preferences and values of individual cancer patients. A discrepancy thus results as regards what "good reasons" are, evoking misunderstandings or even breaking off communication. Suggestions are given for follow up research.

    2017-04-01

    Full Text Available Background: Patients with chronic kidney disease (CKD are at risk to progress to kidney failure. We previously developed the Kidney Failure Risk Equation (KFRE to predict progression to kidney failure in patients referred to nephrologists. Objective: The objective of this study was to determine the ability of the KFRE to discriminate which patients will progress to kidney failure in an unreferred population. Design: A retrospective cohort study was conducted using administrative databases. Setting: This study took place in Manitoba, Canada. Measurements: Age, sex, estimated glomerular filtration rate (eGFR, and urine albumin-to-creatinine ratio (ACR were measured. Methods: We included patients from the Diagnostic Services of Manitoba database with an eGFR <60 mL/min/1.73 m2 and ACR measured between October 2006 and March 2007. Five-year kidney failure risk was predicted using the 4-variable KFRE and compared with treated kidney failure events from the Manitoba Renal Program database. Sensitivity and specificity for KFRE risk thresholds (3% and 10% over 5 years were compared with eGFR thresholds (30 and 45 mL/min/1.73 m2. Results: Of 1512 included patients, 151 developed kidney failure over the 5-year follow-up period. The 4-variable KFRE showed a superior prognostic discrimination compared with eGFR alone (area under the receiver operating characteristic curve [AUROC] values, 0.90 [95% confidence interval {CI}: 0.88-0.92] for KFRE vs 0.78 [95% CI: 0.74-0.83] for eGFR. At a 3% threshold over 5 years, the KFRE had a sensitivity of 97% and a specificity of 62%. At 10% risk, sensitivity was 86%, and specificity was 80%. Limitations: Only 11.7% of stage 3-5 CKD patients had simultaneous ACR measurement. The KFRE does not account for other indications for referral such as suspected glomerulonephritis, polycystic kidney disease, and recurrent stone disease. Conclusions: The KFRE has been validated in a population with a demographic and referral profile

    Full Text Available Treatment abandonment (TxA is recognized as a leading cause of treatment failure for children with cancer in low-and-middle-income countries (LMC. However, its global frequency and burden have remained elusive due to lack of global data. This study aimed to obtain an estimate using survey and population data.Childhood cancer clinicians (medical oncologists, surgeons, and radiation therapists, nurses, social workers, and psychologists involved in care of children with cancer were approached through an online survey February-May 2012. Incidence and population data were obtained from public sources. Descriptive, univariable, and multivariable analyses were conducted.602 responses from 101 countries were obtained from physicians (84%, practicing pediatric hematology/oncology (83% in general or children's hospitals (79%. Results suggested, 23,854 (15% of 155,088 children 6% were outside the capital. Lower national income category, higher reliance on out-of-pocket payments, and high prevalence of economic hardship at the center were independent contextual predictors for TxA ≥ 6% (p<0.001. Global survival data available for more developed and less developed regions suggests TxA may account for at least a third of the survival gap between HIC and LMC.Results show TxA is prevalent (compromising cancer survival for 1 in 7 children globally, confirm the suspected high burden of TxA in LMC, and illustrate the negative impact of poverty on its occurrence. The present estimates may appear small compared to the global burden of child death from malnutrition and infection (measured in millions. However, absolute numbers suggest the burden of TxA in LMC is nearly equivalent to annually losing all kids diagnosed with cancer in HIC just to TxA, without even considering deaths from disease progression, relapse or toxicity-the main causes of childhood cancer mortality in HIC. Results document the importance of monitoring and addressing TxA as part of childhood

    The authors evaluated the risk of development of cholelithiasis in 6050 patients treated at a single hospital for various childhood cancers with different therapeutic modalities, including chemotherapy, surgery, radiation therapy, and bone marrow transplantation, from 1963 to 1989. Patients with underlying chronic hemolytic anemia or preexisting gallstones were excluded. Nine female and seven male patients with a median age of 12.4 years (range, 1.2 to 22.8 years) at diagnosis of primary cancer had gallstones develop 3 months to 17.3 years (median, 3.1 years) after therapy was initiated. Cumulative risks of 0.42% at 10 years and 1.03% at 18 years after diagnosis substantially exceed those reported for the general population of this age group. Treatment-related factors significantly associated with an increased risk of cholelithiasis were ileal conduit, parenteral nutrition, abdominal surgery, and abdominal radiation therapy (relative risks and 95% confidence intervals = 61.6 (27.9-135.9), 23.0 (9.8-54.1), 15.1 (7.1-32.2), and 7.4 (3.2-17.0), respectively). There was no correlation with the type of cancer, nor was the frequency of conventional predisposing features (e.g., family history, obesity, use of oral contraceptives, and pregnancy) any higher among the affected patients in this study than in the general population. Patients with cancer who have risk factors identified here should be monitored for the development of gallstones.

    First-generation molecular profiles for human breast cancers have enabled the identification of features that can predict therapeutic response; however, little is known about how the various data types can best be combined to yield optimal predictors. Collections of breast cancer cell lines mirror many aspects of breast cancer molecular pathobiology, and measurements of their omic and biological therapeutic responses are well-suited for development of strategies to identify the most predictive molecular feature sets. We used least squares-support vector machines and random forest algorithms to identify molecular features associated with responses of a collection of 70 breast cancer cell lines to 90 experimental or approved therapeutic agents. The datasets analyzed included measurements of copy number aberrations, mutations, gene and isoform expression, promoter methylation and protein expression. Transcriptional subtype contributed strongly to response predictors for 25% of compounds, and adding other molecular data types improved prediction for 65%. No single molecular dataset consistently out-performed the others, suggesting that therapeutic response is mediated at multiple levels in the genome. Response predictors were developed and applied to TCGA data, and were found to be present in subsets of those patient samples. These results suggest that matching patients to treatments based on transcriptional subtype will improve response rates, and inclusion of additional features from other profiling data types may provide additional benefit. Further, we suggest a systems biology strategy for guiding clinical trials so that patient cohorts most likely to respond to new therapies may be more efficiently identified.

  15. Irinotecan in the treatment of colorectal cancer.

    Fuchs, Charles; Mitchell, Edith P; Hoff, Paulo M

    2006-11-01

    Irinotecan, a water-soluble, semisynthetic derivative of camptothecin, is a key component of first- and second-line treatment regimens for metastatic colorectal cancer (CRC). In the first-line treatment of metastatic CRC, the results of two prospective, multicenter phase III trials have shown that the combination of irinotecan with bolus or infusional 5-fluorouracil (5FU)/leucovorin (LV) can significantly prolong survival compared with 5FU/LV alone, with a manageable side effects profile. In addition, irinotecan-based regimens, with or without oxaliplatin, may improve resectability of metastases and further increase patient survival. Studies of irinotecan in the first-line setting in combination with newer agents, such as bevacizumab, have shown impressive overall survival. In the second-line setting, irinotecan has demonstrated efficacy superior to that of best supportive care. Initial studies of irinotecan plus bolus 5FU/LV, and the preliminary results from trials of irinotecan plus infusional 5FU/LV in the adjuvant setting, have been disappointing; however, for the largest trial, the Pan-European Trial in Adjuvant Colon Cancer, results with sufficient follow-up are pending. Irinotecan has an acceptable tolerability profile and is not associated with cumulative toxicities in patients with metastatic CRC; regimens containing irinotecan extend treatment duration and improve survival. New regimens and adjunctive therapies are being explored to reduce the incidence of common complications of irinotecan treatment, such as diarrhea and neutropenia.

  16. Theranostic nanoparticles for the treatment of cancer

    Science.gov (United States)

    Moore, Thomas Lee

    The main focus of this research was to evaluate the ability of a novel multifunctional nanoparticle to mediate drug delivery and enable a non-invasive approach to measure drug release kinetics in situ for the treatment of cancer. These goals were approached by developing a nanoparticle consisting of an inorganic core (i.e. gadolinium sulfoxide doped with europium ions or carbon nanotubes). This was coated with an external amphiphilic polymer shell comprised of a biodegradable polyester (i.e. poly(lactide) or poly(glycolide)), and poly(ethylene glycol) block copolymer. In this system, the inorganic core mediates the imaging aspect, the relatively hydrophobic polyester encapsulates hydrophobic anti-cancer drugs, and poly(ethylene glycol) stabilizes the nanoparticle in an aqueous environment. The synthesis of this nanoparticle drug delivery system utilized a simple one-pot room temperature ring-opening polymerization that neglected the use of potentially toxic catalysts and reduced the number of washing steps. This functionalization approach could be applied across a number of inorganic nanoparticle platforms. Coating inorganic nanoparticles with biodegradable polymer was shown to decrease in vitro and in vivo toxicity. Nanoparticles could be further coated with multiple polymer layers to better control drug release characteristics. Finally, loading polymer coated radioluminescent nanoparticles with photoactive drugs enabled a mechanism for measuring drug concentration in situ. The work presented here represents a step forward to developing theranostic nanoparticles that can improve the treatment of cancer.

    HAMLET is a protein-lipid complex that kills different types of cancer cells. Recently we observed a rapid reduction in human bladder cancer size after intravesical HAMLET treatment. In this study we evaluated the therapeutic effect of HAMLET in the mouse MB49 bladder carcinoma model. Bladder tumors were established by intravesical injection of MB49 cells into poly L-lysine treated bladders of C57BL/6 mice. Treatment groups received repeat intravesical HAMLET instillations and controls received alpha-lactalbumin or phosphate buffer. Effects of HAMLET on tumor size and putative apoptotic effects were analyzed in bladder tissue sections. Whole body imaging was used to study HAMLET distribution in tumor bearing mice compared to healthy bladder tissue. HAMLET caused a dose dependent decrease in MB49 cell viability in vitro. Five intravesical HAMLET instillations significantly decreased tumor size and delayed development in vivo compared to controls. TUNEL staining revealed selective apoptotic effects in tumor areas but not in adjacent healthy bladder tissue. On in vivo imaging Alexa-HAMLET was retained for more than 24 hours in the bladder of tumor bearing mice but not in tumor-free bladders or in tumor bearing mice that received Alexa-alpha-lactalbumin. Results show that HAMLET is active as a tumoricidal agent and suggest that topical HAMLET administration may delay bladder cancer development.

    Full Text Available Background: Diabetes and diabetes complications are substantially higher among Canadian First Nations populations compared with the general Canadian population. However, incidence data using detailed individual assessments from a population-based cohort have not been undertaken. Objective: We sought to describe incident diabetes, hypertension and dyslipidemia in a population-based cohort from a Manitoba Ojibway First Nation community. Design: Study data were from 2 diabetes screening studies in Sandy Bay First Nation in Manitoba, Canada, collected in 2002/2003 and 2011/2012. The cohort comprised of respondents to both screening studies (n=171. Health and demographic data were collected using a questionnaire. Fasting blood samples, blood pressure and anthropometric data were also collected objectively. Incident diabetes, hypertension and dyslipidemia were determined. Generalized linear models with Poisson distribution were used to estimate risk of incident diabetes and cardiometabolic conditions according to age and sex. Results: There were 35 (95% CI: 26, 45 new cases of diabetes among 128 participants without diabetes at baseline (27 or 3.3% per year. While participants who were 50 years and older at baseline had a significantly higher risk of incident diabetes at follow-up compared with participants aged 18–29 at baseline (p=0.012, more than half of the incident cases of diabetes occurred among participants aged less than 40 at baseline. There were 28 (95% CI: 20, 37 new cases of dyslipidemia at follow-up among 112 without dyslipidemia at baseline (25%.

  1. Treatment of breast cancer brain metastases.

    Science.gov (United States)

    Hofer, Silvia; Pestalozzi, Bernhard C

    2013-10-05

    Breast cancer represents the second most frequent cause of brain metastases. Treatment planning should consider several tumor and patient factors to estimate prognosis based on the Karnofsky Performance Status (KPS), age, extent of extra-cerebral disease as well as genetic subtype. When systemic disease is under control patients with up to three metastases qualify for local therapy, such as surgical excision or stereotactic radiotherapy. After the local treatment the addition of whole brain radiation therapy may be postponed until disease progression in the brain is observed and overall survival will not be compromised. Asymptomatic brain metastases may be first approached with a systemic treatment to which the primary tumor is considered to be sensitive.

    2010-12-01

    Amphiphilic polymers represented by block copolymers self-assemble into well-defined nanostructures capable of incorporating therapeutics. Polymer nanoassemblies currently developed for cancer treatment and imaging are reviewed in this article. Particular attention is paid to three representative polymer nanoassemblies: polymer micelles, polymer micellar aggregates and polymer vesicles. Rationales, design and performance of these polymer nanoassemblies are addressed, focusing on increasing the solubility and chemical stability of drugs. Also discussed are polymer nanoassembly formation, the distribution of polymer materials in the human body and applications of polymer nanoassemblies for combined therapy and imaging of cancer. Updates on tumor-targeting approaches, based on preclinical and clinical results are provided, as well as solutions for current issues that drug-delivery systems have, such as in vivo stability, tissue penetration and therapeutic efficacy. These are discussed to provide insights on the future development of more effective polymer nanoassemblies for the delivery of therapeutics in the body.

    2010-07-01

    Several drowning fatalities and safety incidents have occurred around dams in Ontario, Manitoba and other jurisdictions in Canada. Following these incidents, Manitoba Hydro implemented several measures to improve public safety around its dams with the development of a warning signs manual. Manitoba Hydro found that a standard centralized approach to the process of improving public safety is better for ensuring compliance and consistency, even though they have safety measures in place. This paper described the process that Manitoba Hydro has followed in developing a formal set of public water safety around dams (PWSD) guidelines and a program for implementing these guidelines. This program was developed with the intent of providing a high standard of public protection and continuous improvement and monitoring on par with the effect spent on similar dam safety type programs. This paper focused on the development of the pilot PWSD management plan for Pine Falls generating station in order to test the effectiveness and usability of the guidelines.

  11. Treatment Considerations for Cancer Pain: A Global Perspective.

    Science.gov (United States)

    Pergolizzi, Joseph V; Gharibo, Christopher; Ho, Kok-Yuen

    2015-11-01

    Cancer pain is prevalent, undertreated, and feared by patients with cancer. In April 2013, a panel of pain experts convened in Singapore to address the treatment of cancer pain. They discussed the various types of cancer pain, including breakthrough pain, which is sometimes clinically confused with analgesic gaps. Reasons for undertreating cancer pain include attitudes of patients, clinicians, and factors associated with healthcare systems. The consequences of not treating cancer pain may include reduced quality of life for patients with cancer (who now live longer than ever), functional decline, and increased psychological stress. Early analgesic intervention for cancer pain may reduce the risk of central sensitization and chronification of pain. To manage pain in oncology patients, clinicians should assess pain during regular follow-up visits using validated pain measurement tools and follow prescribing guidelines, if necessary referring patients with cancer to pain specialists. Many patients with cancer require opioids for pain relief. Pain associated with cancer may also relate to cancer treatments, such as chemotherapy-induced peripheral neuropathy. Many patients with cancer are what might be considered "special populations," in that they may be elderly, frail, comorbid, or have end-stage organ failure. Specific pain therapy guidelines for those populations are reviewed. Patients with cancer with a history of or active substance abuse disorder deserve pain control but may require close medical supervision. While much "treatment inertia" exists in cancer pain control, cancer pain can be safely and effectively managed and should be carried out to alleviate suffering and improve outcomes.

    Cancer is a leading case of mortality worldwide. Governments spent multibillion expenses on treatment and palliative care of diseased people. Despite these generous funding and intensive research with aim to find a cure or efficient treatment for cancer, until now there is a lack in selective cancer management strategies. Conventional treatment strategies for cancer, such as surgery, cytotoxic chemotherapy, radiation therapy, hormone therapy don’t have selectivity toward cancer – the property of discrimination of healthy organs and tissues from the diseased site. Chemotherapy is very challenging as the difference between effective and lethal doses is very minuscule in most cases. Moreover, devastating side effects dramatically changes the quality of life for cancer patients. To address these issues two main strategies are intensively utilized in chemistry: (I) the design and synthesis of novel anticancer organic compounds with higher selectivity and low toxicity profiles and the second, design and preparation of biocompatible nanocarriers for imaging and anticancer compound selective delivery nanomedicine. The following dissertation combines the above two strategies as bellows: First project is related to the design and synthetic route development toward novel nature-inspired group of heterocyclic compounds – iso-Phidianidines. The second project focused on design, preparation and evaluation of hybrid theranostics (therapeutic and diagnostic in a single entity). Chapter 1 is a general background review of the major topics that will be discussed in this dissertation. The first efficient and high-yielding synthetic route toward iso-phidianidines, containing regioisomeric form of 1,2,4-oxadiazole linked to the indole via methylene bridge is reported in Chapter 2. In vitro test of the synthesized library of iso-phidianidines revealed micromolar range of cytotoxicity toward human cervical cancer cell line. Structure activity relationship revealed the importance of

    Full Text Available Gene silencing resulting from aberrant DNA methylation can lead to tumorigenesis. Therefore, drugs that inhibit or interfere with DNA methylation have been used to reactivate and induce silenced gene re-expression in malignancies. Two demethylating agents, azacitidine and decitabine, are approved for the treatment of myelodysplastic syndromes (MDS by the U.S. Food and Drug Administration (FDA, and are now considered the standard of care in MDS. In this review, we discuss clinical data, including clinical benefits and toxicities, which led to the approval of azacitidine and decitabine. We also summarize findings from clinical trials that used these two demethylating agents in the treatment of solid tumors. Lastly, we discuss some limitations in the use of azacitidine and decitabine in cancer therapy.

    Prostate cancer affects one in six American men. Erectile and sexual dysfunctions are long-term side effects of prostate cancer treatment. PubMed database was searched for papers on prostate cancer-related sexual recovery for men and couples. The search yielded articles on (1) the treatment of erectile dysfunction, (2) men's psychological and culturally diverse adaptation to the sexual side effects; (3) the impact of prostate cancer on couples' relationships; and (4) interventions to promote sexual function. Erectile dysfunction after prostate cancer treatment has been widely studied. Research on the sexual recovery of men and couples or understanding it in a cultural context is scarce. Greater focus on the impact of sexual sequelae of prostate cancer treatment on men as well as couples in diverse groups is needed. Clinical implications for treating sexual dysfunction and promoting sexual recovery for prostate cancer survivors and their partners are discussed. Recommendations for future research are provided.

    Answer questions and earn CME/CNE Oral complications resulting from cancer and cancer therapies cause acute and late toxicities that may be underreported, underrecognized, and undertreated. Recent advances in cancer treatment have led to changes in the incidence, nature, and severity of oral complications. As the number of survivors increases, it is becoming increasingly recognized that the aggressive management of oral toxicities is needed to ensure optimal long-term oral health and general well-being. Advances in care have had an impact on previously recognized oral complications and are leading to newly recognized adverse effects. Here, the authors briefly review advances in cancer therapy, including recent advances in surgery, oral care, radiation therapy, hematopoietic cell transplantation, and medical oncology; describe how these advances affect oral health; and discuss the frequent and/or severe oral health complications associated with cancer and cancer treatment and their effect upon long-term health. Although some of the acute oral toxicities of cancer therapies may be reduced, they remain essentially unavoidable. The significant impact of long-term complications requires increased awareness and recognition to promote prevention and appropriate intervention. It is therefore important for the primary oncologist to be aware of these complications so that appropriate measures can be implemented in a timely manner. Prevention and management is best provided via multidisciplinary health care teams, which must be integrated and communicate effectively in order to provide the best patient care in a coordinated manner at the appropriate time.

As with the other vinca alkaloids, the main antineoplastic effects of VFL arise from its interaction with tubulin, the major component of microtubules in mitotic spindles. In contrast to other vinca alkaloids, VFL shows some distinctive properties in terms of tubulin binding, possibly explaining its superior antitumor activity in vitro and in vivo compared with vinorelbine as well as its excellent safety profile. In transitional cell carcinoma (TCC, two single-agent phase II trials were performed testing VFL in platinum-pretreated patients, showing moderate response rates and promising disease control rates. Therefore, the first phase III trial in modern times for second-line TCC of the urothelium was designed in order to further investigate the activity of VFL. First results were presented at the 2008 ASCO conference. VFL appears to be a possible treatment option for patients with TCC progressing after first-line platinum-containing chemotherapy.Keywords: vinflunine, transitional cell carcinoma (TCC of the bladder, bladder cancer, chemotherapy, second-line chemotherapy

    Glucocorticoids have been used in the treatment of prostate cancer to slow disease progression, improve pain control and offset side effects of chemo-and hormonal therapy. However, they may also have the potential to drive prostate cancer growth via mutated androgen receptors or glucocorticoid receptors (GRs). In this review we examine historical and contemporary use of glucocorticoids in the treatment of prostate cancer, review potential mechanisms by which they may inhibit or drive prostate cancer growth, and describe potential means of deifning their contribution to the biology of prostate cancer.

    Cold atmospheric plasma (CAP) constitutes a "cocktail" of various reactive species. Accumulating evidence shows the effectiveness of CAP in killing cancer cells and decreasing the tumor size, which provides a solid basis for its potential use in cancer treatment. Currently, CAP is mainly used to directly treat cancer cells and trigger the death of cancer cells via apoptosis or necrosis. By altering the concentration of fetal bovine serum in Dulbecco's modified Eagle's medium and the temperature to store CAP stimulated media, we demonstrated controllable strategies to harness the stimulated media to kill glioblastoma cells in vitro. This study demonstrated the significant role of media in killing cancer cells via the CAP treatment.

    Passero, Frank C; Saif, Muhammad Wasif

    2017-08-18

    ABTRACT Introduction: Patients with advanced pancreatic cancer (APC) refractory to first-line therapy have a dismal prognosis and limited therapeutic options, with only one option consisting of nanoliposomal irinotecan in combination with fluorouracil and folinic acid which was approved by FDA based upon results of the phase III NAPOLI-1 study. Areas covered: We performed a literature search for relevant published clinical trials, abstracts of trials in progress and ongoing or planned trials for the second line treatment of APC using Pubmed.com, ClinicalTrials.gov and American Society of Clinical Oncology (ASCO) abstract search as sources. We present an in-depth analysis of the phase I-III clinical trials determining the role and efficacy of second-line treatment in patients with APC. We also describe ongoing studies and rationale for future investigation. Expert opinion: Despite advances in first-line therapy such as gemcitabine/nab-paclitaxel and FOLFIRINOX in APC, median overall survival remains less than 12 months, highlighting the need to develop second-line therapies. In order to establish much needed effective second-line treatment options, we need cooperative efforts among institutions and community practices in enrolling these refractory patients in clinical trials. It should be emphasized that in addition to chemotherapy options, all patients should have the opportunity to consult with nutritionist, social worker and palliative care health providers to assist with goals of care, symptom management and end of life discussions.

    Objective To examine self-reported symptoms by the patients receiving cancer therapy, and find out the symptoms that should be coped with and managed during the treatment. Methods A pilot study was conducted on self-reported symptoms on 185 patients receiving chemotherapy and/or radiotherapy for different cancers. The Therapy-Related Symptoms Checklist (TRSC) was used. Results Severe symptoms on the TRSC subscales: loss of appetite,feeling sluggish, weight loss, nausea and hair loss, were reported by the patients. The frequently reported symptoms by those on chemotherapy were nausea, feeling sluggish, weight loss, vomiting, and taste change. The frequently reported symptoms by those on radiotherapy were feeling sluggish, weight loss, loss of appetite, difficult sleeping, and changing taste. The symptoms of loss of appetite, feeling sluggish, weight loss, hair loss, and nausea were both frequently reported by those on radiotherapy and those on chemotherapy. Conclusion Symptom monitoring may be facilitated by TRSC, based on the severity and frequency of reported symptoms, more patients and caregivers could know which symptoms should be preferential interventions.

  4. Diurnal temperature asymmetries and fog at Churchill, Manitoba

    Science.gov (United States)

    Gough, William A.; He, Dianze

    2015-07-01

    A variety of methods are available to calculate daily mean temperature. We explore how the difference between two commonly used methods provides insight into the local climate of Churchill, Manitoba. In particular, we found that these differences related closely to seasonal fog. A strong statistically significant correlation was found between the fog frequency (hours per day) and the diurnal temperature asymmetries of the surface temperature using the difference between the min/max and 24-h methods of daily temperature calculation. The relationship was particularly strong for winter, spring and summer. Autumn appears to experience the joint effect of fog formation and the radiative effect of snow cover. The results of this study suggests that subtle variations of diurnality of temperature, as measured in the difference of the two mean temperature methods of calculation, may be used as a proxy for fog detection in the Hudson Bay region. These results also provide a cautionary note for the spatial analysis of mean temperatures using data derived from the two different methods particularly in areas that are fog prone.

  5. Impact of hydroelectric development upon a northern Manitoba native community

    Waldram, J.B.

    1983-01-01

    This dissertation describes the process of underdevelopment among the Cree Indian people of South Indian Lake, in Northern Manitoba, Canada, following the construction of the Churchill-Nelson River Hydro Project in 1975. The dissertation seeks to link the ecological, political, economic, socio-cultural and health aspects of the impact of the hydro project within the framework of the historical process of underdevelopment as it has occurred in Latin America, among Native people in the United States, and among Native people in Northern Canada. Utilizing both qualitative and quantitative data, a process of increased dependence is described as the product of two related processes. The first process is the impairment of the local commercial and domestic economy caused by the flooding of Southern Indian Lake, which has resulted in a decline in local productivity. The second process is the enhancement of consumerism through rising consumer expectations and a post-project increase in available goods and services which the people are increasingly unable to afford. The overall result has been a process of economic divergence at the local level. The dissertation concludes that the process of underdevelopment which has occurred in South Indian Lake has been the result primarily of changes in the local ecological system caused by the construction of the hydro project. These ecological changes have, in turn, resulted in secondary changes in the socio-economic system.

  6. Anurans in a Subarctic Tundra Landscape Near Cape Churchill, Manitoba

    2008-01-01

    Distribution, abundance, and habitat relationships of anurans inhabiting subarctic regions are poorly understood, and anuran monitoring protocols developed for temperate regions may not be applicable across large roadless areas of northern landscapes. In addition, arctic and subarctic regions of North America are predicted to experience changes in climate and, in some areas, are experiencing habitat alteration due to high rates of herbivory by breeding and migrating waterfowl. To better understand subarctic anuran abundance, distribution, and habitat associations, we conducted anuran calling surveys in the Cape Churchill region of Wapusk National Park, Manitoba, Canada, in 2004 and 2005. We conducted surveys along ~l-km transects distributed across three landscape types (coastal tundra, interior sedge meadow-tundra, and boreal forest-tundra interface) to estimate densities and probabilities of detection of Boreal Chorus Frogs (Pseudacris maculata) and Wood Frogs (Lithobates sylvaticus). We detected a Wood Frog or Boreal Chorus Frog on 22 (87%) of 26 transects surveyed, but probability of detection varied between years and species and among landscape types. Estimated densities of both species increased from the coastal zone inland toward the boreal forest edge. Our results suggest anurans occur across all three landscape types in our study area, but that species-specific spatial patterns exist in their abundances. Considerations for both spatial and temporal variation in abundance and detection probability need to be incorporated into surveys and monitoring programs for subarctic anurans.

    Morrison, Belinda F; Aiken, William D; Mayhew, Richard

    2014-01-01

    Prostate cancer is the commonest cancer in Jamaica as well as the leading cause of cancer-related deaths. One report suggested that Jamaica has the highest incidence rate of prostate cancer in the world, with an age-standardised rate of 304/100,000 per year. The Caribbean region is reported to have the highest mortality rate of prostate cancer worldwide. Prostate cancer accounts for a large portion of the clinical practice for health-care practitioners in Jamaica. The Jamaica Urological Society is a professional body comprising 19 urologists in Jamaica who provide most of the care for men with prostate cancer in collaboration with medical oncologists, radiation oncologists, and a palliative care physician. The health-care system is structured in two tiers in Jamaica: public and private. The urologist-to-patient ratio is high, and this limits adequate urological care. Screening for prostate cancer is not a national policy in Jamaica. However, the Jamaica Urological Society and the Jamaica Cancer Society work synergistically to promote screening as well as to provide patient education for prostate cancer. Adequate treatment for localised prostate cancer is available in Jamaica in the forms of active surveillance, nerve-sparing radical retropubic prostatectomy, external beam radiation, and brachytherapy. However, there is a geographic maldistribution of centres that provide prostate cancer treatment, which leads to treatment delays. Also, there is difficulty in affording some treatment options in the private health-care sectors. Androgen deprivation therapy is available for treatment of locally advanced and metastatic prostate cancer and is subsidised through a programme called the National Health Fund. Second-line hormonal agents and chemotherapeutic agents are available but are costly to most of the population. The infrastructure for treatment of prostate cancer in Jamaica is good, but it requires additional technological advances as well as additional specialist

    Full Text Available Over the past decade, significant data have shown that obese men experience a survival detriment after treatment for prostate cancer. While methods to combat obesity are of utmost importance for the prostate cancer patient, newer data reveal the overall metabolic improvements that accompany increased activity levels and intense exercise beyond weight loss. Along these lines, a plethora of data have shown improvement in prostate cancer-specific outcomes after treatment accompanied with these activity levels. This review discusses the metabolic mechanisms in which increased activity levels and exercise can help improve both outcomes for men treated for prostate cancer while lowering the side effects of treatment.

We can predict the types of cancer when a small abnormal change change occurs on skin by raman spectrum. When we applied the cancer causing chemicals, bezopyrene, to nude mouse, it did not develop to cancer. But we had radiated UV light after developed to skin cancer in a few days. We can deduce the development of human skin cancer from the result of nude mouse skin cancer, because the two skin are structurally very similar to each other. From the results of own research we could conform the UV light is essential for the development of skin cancer. The results of own research can be directly apply to early detection and proper treatment of skin cancer in hospital. 32 refs., 40 figs., 16 tabs. (Author)

Often diagnosed at an advanced stage, the treatment of gastric cancer with chemotherapy is directed towards palliating cancer related symptoms with only modest improvements in survival. In addition, no regimen has emerged as a globally accepted standard. New therapeutic options are desperately needed for the treatment of gastric cancer. Docetaxel given in combination has recently emerged as a new option for patients with advanced gastric cancer. This review focuses on the treatment of advanced gastric cancer utilizing docetaxelbased therapy and the novel additions of biotherapy to the existing cytotoxic platforms. In addition, the current investigations of docetaxel for the treatment of potentially curable gastric cancer will be discussed.Keywords: docetaxel, gastric cancer, chemotherapy, biotherapy

  2. Variation in the structure of bird nests between northern Manitoba and southeastern Ontario.

    Directory of Open Access Journals (Sweden)

    Carla A Crossman

    Full Text Available Traits that converge in appearance under similar environmental conditions among phylogenetically independent lineages are thought to represent adaptations to local environments. We tested for convergence in nest morphology and composition of birds breeding in two ecologically different locations in Canada: Churchill in northern Manitoba and Elgin in southeastern Ontario. We examined nests from four families of passerine birds (Turdidae: Turdus, Parulidae: Dendroica, Emberizidae: Passerculus and Fringillidae: Carduelis where closely related populations or species breed in both locations. Nests of American Robins, Yellow Warblers, and Carduelis finches had heavier nest masses, and tended to have thicker nest-walls, in northern Manitoba compared with conspecifics or congenerics breeding in southeastern Ontario. Together, all species showed evidence for wider internal and external nest-cup diameters in northern Manitoba, while individual species showed varying patterns for internal nest-cup and external nest depths. American Robins, Yellow Warblers, and Carduelis finches in northern Manitoba achieved heavier nest masses in different ways. American Robins increased all materials in similar proportions, and Yellow Warblers and Common Redpolls used greater amounts of select materials. While changes in nest composition vary uniquely for each species, the pattern of larger nests in northern Manitoba compared to southeastern Ontario in three of our four phylogenetically-independent comparisons suggests that birds are adapting to similar selective pressures between locations.

    Gastric cancer ranks the fourth most prevalent malignancy yet it is the second leading cause of cancer-related death. Every year, gastric cancer adds nearly 1 million new cancer cases, and 723,000 or 10%of cancer deaths to the global cancer burden. Approximately, 405,000 or 43%of the new cases and 325,000 or 45%of the deaths are in China, mak-ing gastric cancer a particularly challenging malignancy. This thematic series discusses the molecular classiifcations of gastric cancer by the Cancer Genome Atlas ( TCGA) and the Asian Cancer Research Group (ACRG) as well as the implications in personalized therapeutic choices;discusses the evolution of gastric surgery and presents perspectives on surgical techniques in treating gastric cancer;and reviews current and emerging targeted agents as well as immu-notherapies in treating gastric cancer. With these advancements in molecular characterization, surgical intervention, and targeted and immunotherapies, gastric cancer will enter a personalized medicine era in the next 5 years.

    As we gain a better understanding of the factors affecting cancer etiology, we can design improved treatment strategies. Over the past three to four decades, there have been numerous successful efforts in recognizing important cellular proteins essential in cancer growth and therefore these proteins have been targeted for cancer treatment. However, studies have shown that targeting one or two proteins in the complex cancer cascade may not be sufficient in controlling and/or inhibiting cancer growth. Therefore, there is a need to examine features which are potentially involved in multiple facets of cancer development. In this review we discuss the targeting of the elevated copper (both in serum and tumor) and oxidative stress levels in cancer with the aid of a copper chelator d-penicillamine (d-pen) for potential cancer treatment. Numerous studies in the literature have reported that both the serum and tumor copper levels are elevated in a variety of malignancies, including both solid tumor and blood cancer. Further, the elevated copper levels have been shown to be directly correlated to cancer progression. Enhanced levels of intrinsic oxidative stress has been shown in variety of tumors, possibly due to the combination of factors such as elevated active metabolism, mitochondrial mutation, cytokines, and inflammation. The cancer cells under sustained ROS stress tend to heavily utilize adaptation mechanisms and may exhaust cellular ROS-buffering capacity. Therefore, the elevated copper levels and increased oxidative stress in cancer cells provide for a prospect of selective cancer treatment.

    We explored, via an online questionnaire, knowledge of breast and reproductive system cancers in patients and non-patients who access the internet for information on these diseases. We compared that knowledge to the attention the diseases have received in medical research and on the Internet. Data were collected from 690 respondents (37 % male, 63 % female) about their knowledge of prevalence, lethality, treatments and side effects of testicular, prostate, breast, uterine, cervical and ovarian cancers. Most males, but only half of the female participants, were patients themselves. Although participants showed better knowledge of cancers specific to their own sex, both sexes felt familiar with breast cancer and less aware of other cancers. Women were as aware as men of side effects of treatments for male reproductive cancers. Sex differences in awareness appear to reflect different attitudes towards illness, bias toward females as caregivers, and the disproportionate media attention given to breast cancer.

  9. Current concepts in cancer: effects of cancer and cancer treatment on the nutrition of the host

    The growth of cancer in man leads to destruction of tissues and alterations of functions. The consequences of this process, culminating in overt cachexia and death, are so varied that cancer has replaced syphilis as the great imitator. Many of the manifestations of cachexia (weakness, anorexia, depletion and translocation of host component, and loss of immunocompetence) resemble malnutrition and are accountable for, in many patients, by poor nutritional intake, neoplastic invasion of the gastrointestinal tract or creation by the tumor of abnormal routes through which nutrients can be lost. The development of cachexia, nevertheless, bears no simple relation to caloric intake, tumor burden, tumor cell type or anatomic site of involvement. Indeed, it has long been apparent that, in many patients succumbing to cancer, if the same lesions were composed of scar tissue rather than neoplastic cells, the affected individuals might not only be alive but in reasonably good health. Distant metabolic effects of cancers have therefore come into focus, are well documented and are known collectively as paraneoplastic syndromes. They imply release by the tumor of chemically identifiable toxic mediators. Recently, a third mechanism has been recognized as an important determinant of cachexia and malnutrition: cancer treatment. As our tools have become more powerful and our philosophies more agressive,the effects of therapy on normal cell populations have become visible. The present paper discusses the most important manifestations of cachexia that resemble malnutrition. Technics of nutritional assessment and intervention that have proved successful in patients with cancer are also briefly discussed.

  10. Apoptotic pathways as a therapeutic target for colorectal cancer treatment

    Institute of Scientific and Technical Information of China (English)

    Aman M Abraha; Ezra B Ketema

    2016-01-01

    Colorectal cancer is the second leading cause of death from cancer among adults. The disease begins as a benign adenomatous polyp, which develops into an advanced adenoma with high-grade dysplasia and then progresses to an invasive cancer. Appropriate apoptotic signaling is fundamentally important to preserve a healthy balance between cell death and cell survival and in maintaining genome integrity. Evasion of apoptotic pathway has been established as a prominent hallmark of several cancers. During colorectal cancer development, the balance between the rates of cell growth and apoptosis that maintains intestinal epithelial cell homeostasis gets progressively disturbed. Evidences are increasingly available to support the hypothesis that failure of apoptosis may be an important factor in the evolution of colorectal cancer and its poor response to chemotherapy and radiation. The other reason for targeting apoptotic pathway in the treatment of cancer is based on the observation that this process is deregulated in cancer cells but not in normal cells. As a result, colorectal cancer therapies designed to stimulate apoptosis in target cells would play a critical role in controlling its development and progression. A better understanding of the apoptotic signaling pathways, and the mechanisms by which cancer cells evade apoptotic death might lead to effective therapeutic strategies to inhibit cancer cell proliferation with minimal toxicity and high responses to chemotherapy. In this review, we analyzed the current understanding and future promises of apoptotic pathways as a therapeutic target in colorectal cancer treatment.

Exosomes are nanoscale lipid membrane vesicles derived from multivesicles, which containing active biomolecules including proteins, lipids, nucleic acids and etc. Exosomes play important roles in lung cancer initiation and progression by promoting the formation of tumor microenvironment, enhancing tumor invasive and metastasis capability, leading to immunosuppression and resistance to chemoradiotherapy, and also have the application value in early diagnosis and treatment. This review summarizes the research progress of exosomes in tumor initiation and progression, and its roles in diagnosis and treatment of lung cancer.

  14. Ethanol: the promise and the peril : Should Manitoba expand ethanol subsidies?[A critical analysis of the case for subsidizing ethanol production in Manitoba

    Ethanol is produced through the fermentation of wheat. Blending ethanol with gasoline results in an ethanol-blended gasoline (EBG). Manitoba has already established an ethanol industry in the province and the government of the province is studying the feasibility of expansion. Every year in Manitoba, approximately 90 million litres of EBG are consumed, and the province's ethanol facility also produces a high protein cattle feed called distillers dry grain. Controversies surround the ethanol industry over both the economics and the environmental benefits and impacts. At issue is the economic efficiency of the production of ethanol, where opponents claim that the final product contains less energy than that required to produce it. A small gain is obtained, as revealed by a recent study. It is difficult to quantify the environmental effects of the ethanol industry, whether they be negative or positive. The author indicates that no matter what happens, the gasoline market in Manitoba is so small when compared to the rest of the world that the effect will not be significant. The three methods for the production of ethanol are: (1) the most risky and expensive method is the stand alone ethanol production facility, (2) integrated facilities where other products are produced, such as wet mash or nutraceuticals, and (3) integrated facilities where dry mash can be exported as a high protein feed. The production of a wide range of products is clearly the best option to be considered during the design of an ethanol facility. Price collapse and the capitalizing of subsidies into prices are the main risks facing the expansion of ethanol production in Manitoba. The author states that direct subsidies and price supports should be avoided, since subsidies would encourage the conversion of more feed grain into ethanol. The feed shortage would worsen especially as Manitoba does not currently produce enough feed to support its growing livestock industry. The author concludes that

    Second malignant neoplasms, cardiovascular disease, neurotoxicity and ototoxicity, pulmonary complications, hypogonadism, and nephrotoxicity are potentially life-threatening long-term complications of testicular cancer and its therapy. This article describes the pathogenesis, risks, and management of these late effects experienced by long-term testicular cancer survivors, who are defined as individuals who are disease free 5 years or more after primary treatment. Testicular cancer survivors should follow applicable national guidelines for cancer screening and management of cardiovascular disease risk factors. In addition, health care providers should capitalize on the time of cancer diagnosis as a teachable moment to introduce and promote lifestyle changes.

    Current estimates from the American Cancer Society and from the International Union Against Cancer indicate that 12 million cases of cancer were diagnosed last year, with 7 million deaths worldwide; these numbers are expected to double by 2030 (27 million cases with 17 million deaths). Despite tremendous technological developments in all areas, and President Richard Nixon's initiative in the 1974 "War against Cancer", the US cancer incidence is the highest in the world and the cancer death rate has not significantly changed in the last 50 years (193.9 per 100,000 in 1950 vs 193.4 per 100,000 in 2002). Extensive research during the same time, however, has revealed that cancer is a preventable disease that requires major changes in life style; with one third of all cancers assigned to Tobacco, one third to diet, and remaining one third to the environment. Approximately 20 billion dollars are spent annually to find a cure for cancer. We propose that our inability to find a cure to cancer lies in the models used. Whether cell culture or animal studies, no model has yet been found that can reproduce the pathogenesis of the disease in the laboratory. Mono-targeted therapies, till know in most cases, have done a little to make a difference in cancer treatment. Similarly, molecular signatures/predictors of the diagnosis of the disease and response are also lacking. This review discusses the pros and cons of current cancer models based on cancer genetics, cell culture, animal models, cancer biomarkers/signature, cancer stem cells, cancer cell signaling, targeted therapies, therapeutic targets, clinical trials, cancer prevention, personalized medicine, and off-label uses to find a cure for cancer and demonstrates an urgent need for "out of the box" approaches.

  2. Gender, politics, and regionalism: factors in the evolution of registered psychiatric nursing in Manitoba, 1920-1960.

    Science.gov (United States)

    2011-01-01

    In Canada, psychiatric nursing care is provided by two kinds of nurses. East of Manitoba, it is provided by registered nurses who may or may not have specialized psychiatric nursing education. In the four western provinces, a distinct professional group, registered psychiatric nurses, also provide care. Saskatchewan was the first province to achieve distinct legislation, in 1948, followed by British Columbia in 1951, Alberta in 1955, and Manitoba in 1960. Several factors coalesced to sway Manitoba to adopt the distinct profession model. First, there was little interest by the general nursing body in mental hospital nursing. Second, the other three western provinces had formed a Canadian Council of Psychiatric Nursing that encouraged mental hospital attendants and nurses in Manitoba. Third, a group of male attendants took on leadership roles supported by the mental hospital superintendents.

    Full Text Available Abstract Background The study describes population level variations in campylobacter incidence within the Canadian province of Manitoba, and the relationship to sociodemographic and landscape related characteristics. Using data derived from the Manitoba Health Public Health Branch communicable disease surveillance database, the study applied a number of spatial and ecological techniques to visualize, explore and model campylobacter incidence for the years 1996 to 2004. Analytical techniques used in the study included spatial smoothing, the spatial scan statistic, the Gini coefficient, and Poisson regression analysis. Results The study demonstrated marked and statistically significant geographic variability in the rates of campylobacter incidence in Manitoba.. The incidence of campylobacter was observed to be significantly higher in populations living in rural and agricultural areas of the province, with the highest rates occurring in populations living in proximity to high densities of farm animals (cows, pigs, chickens. The study also observed that the age specific pattern of campylobacter incidence in rural Manitoba was very different than the urban pattern, with the incidence rate in the 0–4 year age group seven times higher in rural Manitoba than in the City of Winnipeg. Conclusion The study demonstrates the value of a deploying a diverse set of spatial techniques to better understand the dynamics of an enteric disease such as campylobacter infection. The study concludes that there may be three distinct mechanisms for the transmission of campylobacter in Manitoba which are operating simultaneously. These include broad population exposure to a centralized food system endemically infected with the campylobacter organism, exposure to local level factors such as farm animals or contaminated water, and exposure to campylobacter infection through foreign travel.

    To investigate whether there is an increased risk of cancer associated with lithium treatment in patients with bipolar disorder compared to the general population. A nationwide Swedish register study of incidence rate ratios (IRRs) of total cancer and site-specific cancer in the 50-84-year age range was carried out in patients with bipolar disorder (n = 5,442) with and without lithium treatment from July 2005 to December 2009 compared to the general population using linked information from The Swedish Cancer Register, The National Patient Register, and The Drug Prescription Register. The overall cancer risk was not increased in patients with bipolar disorder. There was no difference in risk of unspecified cancer, neither in patients with lithium treatment compared to the general population [IRR = 1.04, 95% confidence interval (CI): 0.89-1.23] nor in patients with bipolar disorder without lithium treatment compared to the general population (IRR = 1.03, 95% CI: 0.89-1.19). The cancer risk was significantly increased in patients with bipolar disorder without lithium treatment in the digestive organs (IRR = 1.47, 95% CI: 1.12-1.93), in the respiratory system and intrathoracic organs (IRR = 1.72, 95% CI: 1.11-2.66), and in the endocrine glands and related structures (IRR = 2.60, 95% CI: 1.24-5.47), but in patients with bipolar disorder with lithium treatment, there was no significantly increased cancer risk compared to the general population. Bipolar disorder was not associated with increased cancer incidence and neither was lithium treatment in these patients. Specifically, there was an increased risk of respiratory, gastrointestinal, and endocrine cancer in patients with bipolar disorder without lithium treatment. © 2016 John Wiley & Sons A/S.

  5. Living proof and the pseudoscience of alternative cancer treatments.

    Vickers, Andrew J; Cassileth, Barrie R

    2008-01-01

    Michael Gearin-Tosh was an English professor at Oxford University who was diagnosed with multiple myeloma in 1994. He rejected conventional chemotherapeutic approaches and turned to a variety of alternative cancer treatments, particularly those involving nutritional supplements and dietary change. In 2002, Dr. Gearin-Tosh published a book, Living Proof: A Medical Mutiny, recounting his experiences. The book gained significant public and media attention. One chapter was written by Carmen Wheatley, an advocate of alternative cancer treatments. In distinction to Dr. Gearin-Tosh's personal story, Dr. Wheatley makes general claims about cancer treatment that are supposedly based on the research literature. This appears to provide scientific validation for a highly unconventional program of cancer care. However, the scientific case made for alternative cancer treatments in Living Proof does not bear serious examination. There are numerous inaccuracies, omissions, and misrepresentations. Many important claims are either entirely unsubstantiated or not supported by the literature cited. In conclusion, a highly publicized book gives the impression that alternative cancer treatments are supported by scientific research. It also suggests that little progress has been made in the conventional treatment of myeloma. This is highly misleading and may lead to cancer patients rejecting effective treatments.

    Women with breast cancer require information about their cancer and its treatment during the process of treatment decision-making, yet it is unclear if there are barriers to information support. This study explores the experience of making treatment decisions in breast cancer, paying particular attention to the barriers experienced to the provision of information. Using a grounded theory methodology, semi-structured interviews were conducted with 22 women with invasive breast cancer exploring the experience of treatment decision-making. Data was organized using ATLAS.ti software and analyzed using constant comparisons. Analysis of the data showed that barriers to cancer and treatment information include intrapersonal and interpersonal communication challenges (emotional distress, patient-provider communication, "making it personal," access to information) which reside at different levels of the breast cancer experience (individual, dyad, group, organization). A model is provided to depict this experience. Women want information about their cancer and its treatment and experience barriers to information provision at various levels. Satisfactory information provision cannot occur without addressing barriers at every level. Utilizing interprofessional models of care may minimize existing barriers to information provision and empower patients to make satisfying treatment decisions that are consistent with their individual wishes.

  7. The pathogenesis and treatment of cardiac atrophy in cancer cachexia.

    2016-02-15

    Cancer cachexia is a multifactorial syndrome characterized by a progressive loss of skeletal muscle mass associated with significant functional impairment. In addition to a loss of skeletal muscle mass and function, many patients with cancer cachexia also experience cardiac atrophy, remodeling, and dysfunction, which in the field of cancer cachexia is described as cardiac cachexia. The cardiac alterations may be due to underlying heart disease, the cancer itself, or problems initiated by the cancer treatment and, unfortunately, remains largely underappreciated by clinicians and basic scientists. Despite recent major advances in the treatment of cancer, little progress has been made in the treatment of cardiac cachexia in cancer, and much of this is due to lack of information regarding the mechanisms. This review focuses on the cardiac atrophy associated with cancer cachexia, describing some of the known mechanisms and discussing the current and future therapeutic strategies to treat this condition. Above all else, improved awareness of the condition and an increased focus on identification of mechanisms and therapeutic targets will facilitate the eventual development of an effective treatment for cardiac atrophy in cancer cachexia.

    Chemotherapy and radiotherapy in oncology have repercussions in hearing health, and can damage structures of the inner ear. These repercussions usually, result in a bilateral and irreversible hearing loss. To identify sensorineural hearing loss cases with complaints of tinnitus and difficulty in speech understanding and investigate their relationship with the types of chemotherapy and radiotherapy the patients received. Cross-sectional, clinical, observational, analytical, historical cohort study of 58 subjects treated in a public hospital in the state of Sergipe, diagnosed with neoplasia. The subjects were submitted to anamnesis, conventional pure tone audiometry, and speech recognition threshold. Of the 116 ears, 25.9% presented sensorioneural hearing loss characterized by changes in high frequencies. There was a positive correlation between hearing loss and the association of chemotherapy and radiotherapy (p=0.035; R=0.196). The auditory complaint analysis shows that most of the subjects had tinnitus and speech understanding difficulty, even with a normal auditory threshold. Cancer treatment causes hearing loss, associated with the administration of chemotherapy and radiotherapy. Cyclophosphamide increased the risk of causing hearing loss. Complaints of tinnitus and speech understanding difficulty were observed. Copyright © 2015 Associação Brasileira de Otorrinolaringologia e Cirurgia Cérvico-Facial. Published by Elsevier Editora Ltda.

    2008-01-01

    In recent years there has been an increase in the interest of cancer patients in receiving complementary medicine therapies as supportive measures to cure the disease. In response, medical units that combine conventional and complementary medicine (integrative medicine) have been established in leading cancer centers worldwide. In Israel, a special integrative medicine unit that combines mind-body, Chinese medicine, nutrition, herbs, supplements, and manual therapies (such as shiatsu) before, during and after conventional anti-cancer therapies has been established as an integral part of the Davidoff Comprehensive Cancer Center in 2006. Shiatsu represents a group of manual therapeutic techniques, including acupressure. Shiatsu offers cancer patients a non-pharmacologic method to relieve symptoms and improve quality of life throughout the course of illness. Research indicates that acupressure is relatively effective and safe for common cancer-related symptoms such as nausea, vomiting and insomnia. In our experience, shiatsu is also relatively effective and safe for other common symptoms such as fatigue, muscular pain and body image dissatisfaction. Yet, insufficient evidence exists to delineate the best means by which shiatsu and other manual therapies could or should be integrated into routine cancer care. The purpose of the present paper is to describe what is currently known about this topic in order to support decision-making that is based on facts, rather than on myths and misconceptions. We call for more research that examines the effectiveness and safety of shiatsu and other manual therapies in the care of cancer patients.

    This study aimed to describe the contemporary role of the oncology nurse throughout the entire cancer shared decision-making (SDM) process. Study participants consisted of 30 nurses and nurse practitioners who are actively involved in direct care of patients with cancer in the inpatient or outpatient setting. The major themes that emerged from the content analysis are: oncology nurses have various roles at different time points and settings of cancer SDM processes; patient education, advocacy, and treatment side effects management are among the top nursing roles; oncology nurses value their participation in the cancer SDM process; oncology nurses believe they have a voice, but with various degrees of influence in actual treatment decisions; nurses' level of disease knowledge influences the degree of participation in cancer SDM; and the nursing role during cancer SDM can be complicated and requires flexibility.

    Abstract Double primary liver cancer (DPLC) is a special type of clinical situation. As such, a detailed analysis of the surgical management and prognosis of patients with DPLC is lacking. The objective of the current study was to define the management and outcome of patients undergoing surgery for DPLC at a major hepatobiliary center. A total of 87 patients treated by surgical resection at the Eastern Hepatobiliary Surgery Hospital from January 1st, 2007 to October 31st, 2013 who had DPLC demonstrated by final pathological diagnosis were identified. Among these, 50 patients had complete clinical and prognostic data. Demographic and tumor characteristics as well as the prognosis were analyzed. The proportion of hepatitis B surface antigen (HBsAg) (+) and hepatitis B virus e antigen (HBeAg) (+), HBsAg (+), and HBeAg (−) hepatocirrhosis in all patients was 21.84%, 67.82%, and 63.22%, respectively. Incidental findings accounted for 58.62% of patients; among those who had symptoms, the main symptom was abdominal pain (31.03%). Nonanatomic wedge resection was the main operative approach (62.07%). Postoperatively, the main complications included seroperitoneum (11.49%), hypoproteinemia (10.34%), and pleural effusion (8.05%). Factors associated with disease-free survival (DFS) included intrahepatic cholangiocarcinoma (ICC) tumor size (P = 0.002) and use of postoperative prophylactic transcatheter arterial chemoembolization (TACE) treatment (P = 0.015). Meanwhile, hepatocellular carcinoma (HCC) size (P = 0.045), ICC size (P < 0.001), and liver function (including aspartate aminotransferase [P = 0.001] and r-glutamyl transferase [P < 0.001]) were associated with overall survival (OS). Hepatitis B virus (HBV)-related hepatitis or cirrhosis is also an important factor in the pathogenesis of DPLC and surgical treatment is safe for it with low complication rates. In addition, it is effective to prolong DFS that DPLC patients undergo postoperative

    Cancer of the exocrine pancreas is a malignancy with a high lethal rate. Surgical resection is the only possible curative mode of treatment. Metastatic pancreatic cancer is incurable with modest results from the current treatment options. New genomic information could prove treatment efficacy. An independent review of PubMed and ScienceDirect databases was performed up to March 2016, using combinations of terms such pancreatic exocrine cancer, chemotherapy, genomic profile, pancreatic cancer pharmacogenomics, genomics, molecular pancreatic pathogenesis, and targeted therapy. Recent genetic studies have identified new markers and therapeutic targets. Our current knowledge of pancreatic cancer genetics must be further advanced to elucidate the molecular basis and pathogenesis of the disease, improve the accuracy of diagnosis, and guide tailor-made therapies.

    Bladder cancer is the sixth most common cancer in the Western world. Patients with bladder cancer require close monitoring, which may include frequent cystoscopy and urine cytology. Such monitoring results in significant health care cost. The application of epigenetics may allow for a risk adapted approach and more cost-effective method of monitoring. A number of epigenetic changes have been described for many cancer sites, including the urinary bladder. In this review, we discuss the use of epigenetics in bladder cancer and the potential diagnostic and therapeutic applications. A comprehensive search of the English medical literature was conducted in PubMed using the terms microRNA regulation, DNA methylation, histone modification and bladder cancer. The most important epigenetic changes include DNA methylation, histone modification and microRNA regulation. Both DNA hypomethylation and hypermethylation have been associated with higher rate of cancer. The association of epigenetic changes with bladder cancer has led to the research of its diagnostic and prognostic implications as well as to the development of novel drugs to target these changes with the aim of achieving a survival benefit. Recently, epigenetics has been shown to play a much greater role than previously anticipated in the initiation and propagation of many tumors. The use of epigenetics for the diagnosis and treatment of bladder cancer is an evolving and promising field. The possibility of reversing epigenetic changes may facilitate additional cancer treatment options in the future.

    Inflammation is one of the most important causes of the majority of cancer symptoms, including pain, fatigue, cachexia, and anorexia. Cancer pain affects 17 million people worldwide and can be caused by different mediators which act in primary efferent neurons directly or indirectly. Cytokines can be aberrantly produced by cancer and immune system cells and are of particular relevance in pain. Currently, there are very few strategies to control the release of cytokines that seems to be related to cancer pain. Nevertheless, in some cases, targeted drugs are available and in use for other diseases. In this paper, we aim to review the importance of cytokines in cancer pain and targeted strategies that can have an impact on controlling this symptom.

  3. Canada's National Building Stone: Tyndall Stone from Manitoba

    Tyndall Stone is a distinctively mottled and highly fossiliferous dolomitic limestone that belongs to the Selkirk Member of the Red River Formation, of Late Ordovician (Katian) age. It has been quarried at Garson, Manitoba, 37 km northeast of Winnipeg, since 1895, although other quarries in the area go back to 1832. Tyndall Stone, so named because it was shipped by rail from nearby Tyndall, is currently produced by Gillis Quarries Limited. It has various uses as a dimension stone. Large slabs, most often cut parallel to bedding, face the exterior or interior of many important buildings such as the Parliament Buildings and the Canadian Museum of Civilization in the Ottawa area, the Empress Hotel in Victoria, and the provincial legislatures in Winnipeg and Regina, as well as many commercial buildings especially in the Canadian prairies. At the quarries, the stone is cut vertically, using eight foot (2.44 m) diameter saws mounted on one hundred foot (30.5 m) tracks, then split into 6-8 tonne blocks that are moved using front-end loaders. Gillis Quarries operates a large finishing plant with an area of about 4000 m2. Stone is processed along advanced cutting lines that feature eight primary saws and six gantry saw stations, allowing it to be made into a variety of sizes, shapes, and finishes. The Selkirk Member is 43 m thick and the stone is extracted from a 6-8 m thick interval within the lower part. The upper beds tend to be more buff-coloured than the grey lower beds due to weathering by groundwater. The stone is massive, but extracted blocks are less than ~1m thick due to splitting along stylolites. Consisting of bioturbated wackestone to packstone, the Tyndall Stone was deposited in a shallow-marine environment within the photic zone, in the central part of the vast equatorial epicontinental sea that covered much of Laurentia. Scattered thin, bioclastic grainstone lenses record brief, low-energy storm events. The distinctive mottles are formed by dolomitized

  4. Preliminary Rock Physics Analysis on Lodgepole Formation in Manitoba, Canada

    Kim, N.; Keehm, Y.

    2012-12-01

    We present rock physics analysis results of Lodgepole Formation, a carbonate reservoir in Daly Field, Manitoba, Canada. We confirmed that the Lodgepole Formation can be divided into six units in the study area: Basal Limestone, Cromer Shale, Cruickshank Crinoidal, Cruickshank Shale, Daly member and Flossie Lake member from the bottom, using eight well log data and previous works. We then performed rock physics analyses on four carbonate units (Basal Limestone, Cruickshank Crinoidal, Daly and Flossie Lake), such as Vp-porosity, AI-porosity, DEM (differential effective medium) modeling, and fluid substitution analysis. In Vp-porosity domain, the top unit, Flossie Lake member has lower porosity and higher velocity, while the other units show similar porosity and velocity. We think that this results from the diagenesis of Flossie Lake member since it bounds with unconformity. However, the four units show very similar trend in Vp-porosity domain, and we can report one Vp-porosity relation for all carbonate units of the Lodgepole formation. We also found that the acoustic impedance varies more than 10% from low porosity zone (3-6%) to high porosity zone (9-12%) from AI-porosity analysis. Thus one can delineate high porosity zone from seismic impedance data. DEM modeling showed that Flossie Lake would have relatively low aspect ratio of pores than the others, which implies that the top unit has been influenced by diagenesis. To determine fluid sensitivity of carbonate units, we conducted fluid substitution on four units from 100% water to 100% oil. The top unit, Flossie Lake, showed slight increase of Vp, which seems to be density effect. The others showed small decrease of Vp, but not significant. If we observe Vp/Vs rather than Vp, the sensitivity increases. However, fluid discrimination would be difficult because of high stiffness of rock frame. In summary, three lower carbonate units of Lodgepole Formation would be prospective and high porosity zone can be delineated

    The survival benefit of extended surgery for advanced pancreatic cancer has been denied by four randomized controlled trials. However, there still is confusion and conflict over the definition and effective treatment strategy for so-called locally advanced or borderline resectable pancreatic cancer. Although there are a number of reports that showed outcomes of preoperative chemotherapy or chemoradiotherapy for this disease, the definitions and treatment regimens described in these studies vary. Moreover, all of the studies were Phase I / II trials or retrospective analysis, and there is no Phase III trial currently focused on this issue. It is urgently necessary to establish an international consensus on the definition of borderline resectable pancreatic cancer. The usefulness of neoadjuvant treatment for this disease should also be elucidated in future clinical trials. In this review article, we discuss the current understanding and definition of borderline resectable pancreatic cancer, and the value of neoadjuvant treatment strategy for treating it.

To overcome these setbacks, new treatment methods have been proposed, few of them seem to be very promising. This scientific paper is an overview of the recent advances in cancer therapy.

  17. Gene expression profiling for targeted cancer treatment.

    Science.gov (United States)

    Yuryev, Anton

    2015-01-01

    There is certain degree of frustration and discontent in the area of microarray gene expression data analysis of cancer datasets. It arises from the mathematical problem called 'curse of dimensionality,' which is due to the small number of samples available in training sets, used for calculating transcriptional signatures from the large number of differentially expressed (DE) genes, measured by microarrays. The new generation of causal reasoning algorithms can provide solutions to the curse of dimensionality by transforming microarray data into activity of a small number of cancer hallmark pathways. This new approach can make feature space dimensionality optimal for mathematical signature calculations. The author reviews the reasons behind the current frustration with transcriptional signatures derived from DE genes in cancer. He also provides an overview of the novel methods for signature calculations based on differentially variable genes and expression regulators. Furthermore, the authors provide perspectives on causal reasoning algorithms that use prior knowledge about regulatory events described in scientific literature to identify expression regulators responsible for the differential expression observed in cancer samples. The author advocates causal reasoning methods to calculate cancer pathway activity signatures. The current challenge for these algorithms is in ensuring quality of the knowledgebase. Indeed, the development of cancer hallmark pathway collections, together with statistical algorithms to transform activity of expression regulators into pathway activity, are necessary for causal reasoning to be used in cancer research.

    An analysis of the results of treatment of 344 patients with cancer of the thoracic part of the esophagus was performed. Out of those, 104 received surgical and combined treatment and 240 (inoperable cancer) were given radiotherapy alone or in combination with local hyperthermia, general chemotherapy or intratumoral iontophoresis of chemotherapeutic agents. The operation after Dobromyslov-Torek proved to be insufficient in most of surgical cases because there were metastatic lesions below the diaphragm. Local hyperthermia potentiated the effect of radiation treatment. The early results of treatment improved after intratumoral sarcolysin ionophoresis was used in conjunction with radiation therapy.

    Gastric cancer is the second leading cause of death from malignant disease worldwide and most frequently discovered in advanced stages. Because curative surgery is regarded as the only option for cure, early detection of resectable gastric cancer is extremely important for good patient outcomes. Therefore, noninvasive diagnostic modalities such as evolutionary endoscopy and positron emission tomography are utilized as screening tools for gastric cancer. To date, early gastric cancer is being treated using minimally invasive methods such as endoscopic treatment and laparoscopic surgery, while in advanced cancer it is necessary to consider multimodality treatment including chemotherapy, radiotherapy, and surgery. Because of the results of large clinical trials, surgery with extended lymphadenectomy could not be recommended as a standard therapy for advanced gastric cancer. Recent clinical trials had shown survival benefits of adjuvant chemotherapy after curative resection compared with surgery alone. In addition, recent advances of molecular targeted agents would play an important role as one of the modalities for advanced gastric cancer. In this review, we summarize the current status of diagnostic technology and treatment for gastric cancer.

    2014-01-01

    Pancreatic cancer is resistant to conventional treatment. The aim of the study was to confirm the hypothesis that changes in cancer stem cells (CSCs) and developmental pathway after treatment was responsible for treatment failure in pancreatic cancer. After recovery from a gemcitabine treatment, the percentage of pancreatic cancer CSCs and Notch pathway in BxPC3 and HPAC pancreatic cancer cell lines were analyzed by FACS (CD24 and CD44) and western blot (Notch1, Hes1, β-catenin, and pAKT). The effect of DAPT, a gamma-secretase inhibitor, was similarly investigated. The association between immunohistochemical expression of Hes1 and survival was analyzed. The percentage of CD24(+)CD44(+) cells was higher in gemcitabine-treated BxPC3 and HPAC cells than at pre-treatment. CD24(+)CD44(+) cells sorted from the gemcitabine-treated cell lines showed higher migration and invasion ability than CD24(-)CD44(-) or CD24(-)CD44(+) cells from the same cell lines. Western blot analysis showed an increased expression of Notch1 and Hes1 in gemcitabine-treated cell lines. The overall survival of pancreatic cancer patients with strong expression of Hes1 was shorter than that in patients with no or weak expression (11.1 vs. 21.6 months, P = 0.036). Treatment with DAPT reversed the increase in Hes1, β-catenin, and pAKT expression and the proportion of CD24(+)CD44(+) cells in gemcitabine-treated cell lines. The treatment also decreased migration and invasion ability. Our data suggested that an increase in CSCs and activation of the Notch pathway might contribute to the failure of treatment in pancreatic cancer. Notch pathway can be a potential target to overcome treatment failure. Copyright © 2013 IAP and EPC. Published by Elsevier B.V. All rights reserved.

    Science.gov (United States)

    Sliva, Daniel

    2003-12-01

    The popular edible mushroom Ganoderma lucidum (Reishi) has been widely used for the general promotion of health and longevity in Asian countries. The dried powder of Ganoderma lucidum was popular as a cancer chemotherapy agent in ancient China. The authors recently demonstrated that Ganoderma lucidum inhibits constitutively active transcription factors nuclear factor kappa B (NF-kappaB) and AP-1, which resulted in the inhibition of expression of urokinase-type plasminogen activator (uPA) and its receptor uPAR. Ganoderma lucidum also suppressed cell adhesion and cell migration of highly invasive breast and prostate cancer cells, suggesting its potency to reduce tumor invasiveness. Thus, Ganoderma lucidum clearly demonstrates anticancer activity in experiments with cancer cells and has possible therapeutic potential as a dietary supplement for an alternative therapy for breast and prostate cancer. However, because of the availability of Ganoderma lucidum from different sources, it is advisable to test its biologic activity.

    Full Text Available Mark R Mawhinney, Robert E GlasgowDepartment of Surgery, Huntsman Cancer Institute at the University of Utah, Salt Lake City, UT, USAAbstract: In recent years, esophageal cancer characteristics and management options have evolved significantly. There has been a sharp increase in the frequency of esophageal adenocarcinoma and a decline in the frequency of squamous cell carcinoma. A more comprehensive understanding of prognostic factors influencing outcome has also been developed. This has led to more management options for esophageal cancer at all stages than ever before. A multidisciplinary, team approach to management in a high volume center is the preferred approach. Each patient should be individually assessed based on type of cancer, local or regional involvement, and his or her own functional status to determine an appropriate treatment regimen. This review will discuss management of esophageal cancer relative to disease progression and patient functional status.Keywords: esophageal adenocarcinoma, squamous cell carcinoma, treatment regimen, disease progression, patient functional status

    Breast cancer is the most common cancer among females worldwide. Several epidemiological studies suggested the inverse correlation between the intake of vegetables and fruits and the incidence of breast cancer. Substantial experimental studies indicated that many dietary natural products could affect the development and progression of breast cancer, such as soy, pomegranate, mangosteen, citrus fruits, apple, grape, mango, cruciferous vegetables, ginger, garlic, black cumin, edible macro-fungi, and cereals. Their anti-breast cancer effects involve various mechanisms of action, such as downregulating ER-α expression and activity, inhibiting proliferation, migration, metastasis and angiogenesis of breast tumor cells, inducing apoptosis and cell cycle arrest, and sensitizing breast tumor cells to radiotherapy and chemotherapy. This review summarizes the potential role of dietary natural products and their major bioactive components in prevention and treatment of breast cancer, and special attention was paid to the mechanisms of action.

    Peritoneal carcinomatosis (PC), the dissemination of cancer cells throughout the lining of the abdominal cavity, is the second most common presentation of colon cancer distant metastasis. Despite remarkable advances in cytotoxic chemotherapy and targeted therapy for colon cancer over the last 15 years, it has been repeatedly shown that these therapies remain ineffective for colon cancer PC. Recently, there has been a rapid accumulation of reports that cytoreductive surgery combined with hyperthermic intraperitoneal chemotherapy (CRS-HIPEC) prolongs the life of colon cancer PC patients. Here, we will review the clinical presentation, the mechanisms of disease progression, and current treatment options for colon cancer PC, with a focus on the benefits and limitations of CRS-HIPEC.

    2016-02-01

    Pancreatic cancer is estimated to be the 12th most common cancer in the United States in 2014 and yet this malignancy is the fourth leading cause of cancer-related death in the United States. Late detection and resistance to therapy are the major causes for its dismal prognosis. Apoptosis is an actively orchestrated cell death mechanism that serves to maintain tissue homoeostasis. Cancer develops from normal cells by accruing significant changes through one or more mechanisms, leading to DNA damage and mutations, which in a normal cell would induce this programmed cell death pathway. As a result, evasion of apoptosis is one of the hallmarks of cancer cells. PDAC is notoriously resistant to apoptosis, thereby explaining its aggressive nature and resistance to conventional treatment modalities. The current review is focus on understanding different intrinsic and extrinsic pathways in pancreatic cancer that may affect apoptosis in this disease.

    About 10% of breast cancers are associated with the inheritance of autosomal dominant breast cancer susceptibility alleles BRCA1 and BRCA2. Until recently, the medical management of BRCA mutation-associated breast cancer has not differed from that of the sporadic breast cancer counterpart. However, there is mounting evidence that this molecular alteration confers sensitivity or resistance to systemic therapies that can be exploited in terms of medical management. For example, studies support the use of platinum salts chemotherapy in BRCA mutated cancers. Moreover, a number of targeted therapies are showing activity in BRCA mutation carriers. Above all, BRCA defective tumor cells are particularly sensitive to Poly(ADP-ribose) polymerase (PARP) inhibitors. This review will summarize the state of the art of the medical treatment of breast cancer in BRCA mutation carriers, with a particular focus on chemotherapies and targeted therapies.

    Full Text Available Multiple primary lung cancer (MPLC is an uncommon entity of the primary lung cancer. With the widespread use of early detection tools such as multislice spiral computed tomography (CT, positron emission tomography (PET, and the better survival results after resection of primary lung cancer, more and more MPLC have been detected. However, the current diagnostic and therapeutic methods cannot meet the needs of MPLC individualized demand of diagnosis and treatment. At present, diagnostic criteria of MPLC are based on histological types, genetic characteristics, image features, tumor locations and clinical manifestation. On the treatment of MPLC, Surgery-based multi-discipline comprehensive treatment is regarded as the treatment of choice. In this paper, we make a review through summarizing the latest literature progress on the epidemiology, etiology, diagnostic criteria, treatment options and prognosis of MPLC.

    Monitoring the cancer response to treatment, non-invasively, by medical imaging is a key element in the management of cancer. For patients undergoing treatment, it is crucial to determine responders from non-responders in order to guide treatment decisions. Currently, PET is the most widely used......, and the patient is exposed to ionizing radiation. The introduction of hyperpolarized 13C MRS has opened completely new possibilities to study the biochemical changes in disease processes. Numerous 13C-labeled compounds were proposed to interrogate various aspects of cancer cell metabolism. The aim of this study...... is to investigate the relevance of [1-13C]pyruvate and [1,4-13C2]fumarate in monitoring the changes in cellular metabolism and necrosis that may occur as a result of cancer therapy.

    Colorectal adenocarcinoma is a major cause of cancer-related morbidity and mortality in Belgium and in other western countries. Prevention implies a modification of alimentation and maybe a chronic uptake of acetylsalicylic acid. Treatment of colorectal cancers is based on surgery and the prognosis is determined by the locoregional or metastatic tumor spread. Complete resection of any Astler Coller stage C colorectal malignant tumor has to be followed by a 5-fluorouracil-based adjuvant chemotherapy. In these protocols, 5-fluorouracil is administered together with folinic acid or levamisole. The administration of an adjuvant chemotherapy could also be considered for stage BII diseases. As rectal cancers are characterized by high local relapse rates, their treatment should associate radiotherapy, given either post-surgery or preferentially pre-surgery, with resection and chemotherapy. Appropriate treatment of colorectal cancers thus requires a concerted multidisciplinary approach.

    Gastrointestinal cancer treatment is based more on molecular biology that has provided increasing knowledge about cancer pathogenesis on which targeted therapy is being developed. Precisely, targeted therapy is defined as a "type of treatment that uses drugs, such as monoclonal antibodies or tyrosine kinase inhibitors, to identify and attack specific cancer cells". Nowadays, the United States Food and Drug Administration has approved many targeted therapies for gastrointestinal cancer treatment, as many are in various phases of development as well. In a previous review we discussed the main monoclonal antibodies used and studied in gastrointestinal cancer. In addition to monoclonal antibodies, tyrosine kinase inhibitors represent another class of targeted therapy and following the approval of imatinib for gastrointestinal stromal tumours, other tyrosine kinase inhibitors have been approved for gastrointestinal cancers treatment such as sunitinib, regoragenib, sorafenib and erlotinib. Moving forward, the purpose of this review is to focus on the efficacy data of main tyrosine kinase inhibitors commonly used in the personalized treatment of each gastrointestinal tumour and to provide a comprehensive overview about experimental targeted therapies ongoing in this setting.

    The terms "alternative" or "unconventional" have been used to describe any therapy used instead of conventional approaches. Conventional approaches, known as "standard" or "traditional" or "biomedical" approaches, have had broad application in Western medicine. Complementary and alternative medicine has been referred to as "integrative," "integrated," or "complementary" when therapies are combined with conventional approaches, such as those for cancer.

    Sperm banking is an important procedure to preserve fertility before cancer therapy. The aim of this study was to comprehensively analyse cryopreservation activity retrospectively for 1080 patients referred to the sperm bank for sperm cryopreservation before cancer treatment. This study included 1007 patients diagnosed with testicular cancer (TC) (41.7%), lymphoma (26%), other haematological cancers (9.4%) or other types of cancer (22.8%); of these, 29 patients did not produce any semen sample and cryopreservation was impossible for 67 patients. Semen characteristics before treatment were within normal ranges, except moderate asthenospermia. Sperm concentration was significantly lower in TC than in non-TC. Straws from 57 patients (6.3%) were used in assisted reproductive technologies, which led to a 46.8% cumulative birth rate. Straws were destroyed for 170 patients (18.7%) and 140 patients performed semen analyses after cancer therapy. After an average delay of 22.5 months after the end of therapy, 43 patients (30.7%) exhibited azoospermia. This study of a large population of cancer patients revealed a high level of successful sperm storage. Utilization of cryopreserved spermatozoa led to good chances of fatherhood. Nevertheless, sperm banks should be aware of the low rates of straw use and straw destruction by cancer patients.

    Sisler, Jeffrey; Chaput, Genevieve; Sussman, Jonathan; Ozokwelu, Emmanuel

    2016-01-01

    Objective To offer FPs a summary of evidence-based recommendations to guide their follow-up survivorship care of women treated for breast cancer. Quality of evidence A literature search was conducted in MEDLINE from 2000 to 2016 using the search words breast cancer, survivorship, follow-up care, aftercare, guidelines, and survivorship care plans, with a focus on review of recent guidelines published by national cancer organizations. Evidence ranges from level I to level III. Main message Survivorship care involves 4 main tasks: surveillance and screening, management of long-term effects, health promotion, and care coordination. Surveillance for recurrence involves only annual mammography, and screening for other cancers should be done according to population guidelines. Management of the long-term effects of cancer and its treatment addresses common issues of pain, fatigue, lymphedema, distress, and medication side effects, as well as longer-term concerns for cardiac and bone health. Health promotion emphasizes the benefits of active lifestyle change in cancer survivors, with an emphasis on physical activity. Survivorship care is enhanced by the involvement of various health professionals and services, and FPs play an important role in care coordination. Conclusion Family physicians are increasingly the main providers of follow-up care after breast cancer treatment. Breast cancer should be viewed as a chronic medical condition even in women who remain disease free, and patients benefit from the approach afforded other chronic conditions in primary care.

  2. Starvation Based Differential Chemotherapy: A Novel Approach for Cancer Treatment

    Directory of Open Access Journals (Sweden)

    2014-11-01

    Full Text Available Cancer patients undergoing chemotherapy treatment are advised to increase food intake to overcome the therapy-induced side effects, and weight loss. Dietary restriction is known to slow down the aging process and hence reduce age-related diseases such as cancer. Fasting or short-term starvation is more effective than dietary restriction to prevent cancer growth since starved cells switch off signals for growth and reproduction and enter a protective mode, while cancer cells, being mutated, are not sensitized by any external growth signals and are not protected against any stress. This phenomenon is known as differential stress resistance (DSR. Nutrient signaling pathways involving growth hormone/insulin-like growth factor-1 axis and its downstream effectors, play a key role in DSR in response to starvation controlling the other cell maintenance systems, such as autophagy and apoptosis, that are related to the tumorigenesis. Yeast cells lacking these effectors are better protected against oxidative stress compared to normal cells. In the same way, starvation protects many cell lines and mice against high-dose chemotherapeutic drugs. According to a series of studies, fasting results in overall reduction in chemotherapy side effects in cancer patients. Data shows that starvation-dependent differential chemotherapy is safe, feasible and effective in cancer treatment, but the possible side effects of starvation limit its efficacy. However, further studies and clinical trials may result in its implementation in cancer treatment.

    Objective To assess cancer patients’ utilization of complementary and alternative medical providers and the associated expenditures by specific treatment phases. Study Design Cross-sectional analysis of medical services utilization and expenditures during three therapeutic intervals: an initial treatment phase, continuing care, and end-of-life. Methods Analysis of an insurance claims database that had been matched to the Washington State SEER cancer registry. Results Of 2,900 registry-matched cancer patients 63.2% were female, the median age was 54 years, and 92.7% were white. Breast cancer was the most frequent diagnosis (52.7%), followed by prostate cancer (24.7%), lung cancer (10.1%), colon cancer (7.0%), and hematologic malignancies (5.6%). CAM provider using patients were 26.5% of the overall cohort (18.5% used chiropractors, 7.7% naturopathic physicians, 5.3% massage therapists, and 4.2% saw acupuncturists). The proportion of CAM using patients was similar during each treatment phase. All patients used some conventional care. Female gender, a breast cancer diagnosis, age, and white race were significant predictors of CAM use. Diagnosis of a musculoskeletal problem occurred at sometime during the study for 72.1% of cancer patients. CAM provider visits were 7.2% of total outpatient medical visits and 85.1% of CAM visits resulted in a musculoskeletal diagnosis. Expenditures for CAM providers were 0.3%, 1.0%, and 0.1% of all expenditures during the initial, continuing, and end-of-life phases respectively. Conclusion For cancer patients, musculoskeletal issues were the most commonly listed diagnosis made by a CAM provider. Although expenditures associated with CAM are a small proportion of the total, additional studies are necessary to determine the importance patients place on access to these services. PMID:18471036

    Given the growing attention to the importance of design in shaping healing hospital environments this study extends the understanding of healing environments, beyond causal links between environmental exposure and health outcome by elucidating how environments and practices interrelate. The study was conducted as an ethnographic fieldwork from March 2011 to September 2011 at the Department of Haematology at Odense University Hospital, Denmark, systematically using participant observation and interviews as research strategies. It included 20 patients, four of who were followed closely over an extended time period. Through thematic analysis five key concepts emerged about the social dynamics of hospital environments: practices of self; creating personal space; social recognition; negotiating space; and ambiguity of space and care. Through these concepts, the study demonstrates how the hospital environment is a flow of relations between space and practice that changes and challenges a structural idea of design and healing. Patients' sense of healing changes with the experience of progression in treatment and the capacity of the hospital space to incite an experience of homeliness and care. Furthermore, cancer patients continuously challenge the use and limits of space by individual objects and practices of privacy and home. Healing environments are complex relations between practices, space and care, where recognition of the individual patient's needs, values and experiences is key to developing the environment to support the patient quality of life. The present study holds implications for practice to inform design of future hospital environments for cancer treatment. The study points to the importance for being attentive to the need for flexible spaces in hospitals that recognize the dynamics of healing, by providing individualized care, relating to the particular and changing needs of patients supporting their potential and their challenged condition with the best

    Pancreatic cancer (PC) is a lethal disease representing the seventh most frequent cause of death from cancer worldwide. Resistance of pancreatic tumors to current treatments leads to disappointing survival rates, and more specific and effective therapies are urgently needed. In recent years, immunotherapy has been proposed as a promising approach to the treatment of PC, and encouraging results have been published by various preclinical and clinical studies. This review provides an overview of the latest developments in the immunotherapeutic treatment of PC and summarizes the most recent and important clinical trials.

  8. Improving cancer treatment by addressing legislative and regulatory issues.

    Olver, I

    2011-12-01

    To explore legislative and legal barriers to improving cancer treatment. The advocacy agenda of Cancer Council Australia was examined for key issues, and examples drawn from Australian law were presented at a conference entitled 'Legislate, regulate and litigate: legal perspectives on cancer prevention and treatment' at the University of Sydney. The introduction of electronic medical records and linkage of data sets from registries can produce very useful public health information, but could be a threat to individual privacy. The balance between these must underpin legislation and regulation. The new drug approval process must keep pace with developments such as targeted therapies, where tests to identify the presence of the target must also be approved simultaneously. The regulation of complementary and alternative medicines in cancer is challenging given their widespread use. In cancer research, it is vital that the important ethics and governance review process does not become a barrier to the ability to complete research in a reasonable time frame. A specific issue for future treatments and diagnostic tests that are to be targeted at genes and their products is to clarify gene patenting laws so that invention is rewarded, not mere discovery. The nature of the workforce will need to change to meet the treatment needs of an increasing incidence of cancer in an aging population, but regulation will need to ensure the maintenance of safety and quality standards. The flexibility of legislation and regulation to meet a rapidly changing environment is key to ensuring the timely adoption of new cancer treatments to improve cancer outcomes. Copyright © 2011.

    Purpose/Objectives To describe the impact of the cancer experience on the health behaviors of survivors’ family members and to determine factors associated with family members’ intentions for health behavior change. Design Descriptive, cross-sectional, correlational study. Setting A National Cancer Institute-designated comprehensive cancer center in the Midwestern United States. Sample 39 family members and 50 patients with diagnoses of breast, colon, head and neck, lung, or prostate cancer who were completing definitive cancer treatment. Methods Patients and family members were approached in the clinic at 3 weeks or less before the completion of their course of treatment. Family members completed surveys and a structured interview in-person or via telephone. Main Research Variables Intention, perceived benefit, and confidence for eating a healthy diet, physical activity, and smoking cessation; emotional distress; and family cohesiveness, conflict, and expressiveness. Findings Family members had, on average, high ratings for intention, perceived benefit, and confidence related to behaviors of eating a healthy diet and doing 30 minutes of daily moderate physical activity. They also had high ratings for the extent to which the cancer experience raised their awareness of their own cancer risk and made them think about having screening tests; ratings were lower for making changes in their health behaviors. Distress scores of family members were high at the completion of cancer treatment. Greater intention for physical activity and nutrition was associated with greater perceived benefit and confidence. Higher scores for family expressiveness was associated with intention for nutrition. Greater intention for smoking cessation was associated only with confidence. Conclusions Family members expressed strong intentions to engage in health-promoting behaviors related to physical activity and nutrition at the transition to post-treatment survivorship.

    2016-01-01

    Gastric (including gastroesophageal junction) cancer is the third leading cause of cancer-related death in the world. In China, an estimated 420,000 patients were diagnosed with gastric cancer in 2011, ranking this malignancy the second most prevalent cancer type and resulting in near 300,000 deaths. The treatment landscape of gastric cancer has evolved in recent years. Although systemic chemotherapy is still the mainstay treatment of metastatic disease, the introduction of agents targeting human epidermal growth factor receptor 2 and vascular endothelial growth factor/vascular endothelia growth factor receptor has brought this disease into the molecular and personalized medicine era. The preliminary yet encouraging clinical effcacy observed with immune checkpoint inhibitors, e.g., anti-pro-grammed cell death protein 1/programmed death-ligand 1, will further shape the treatment landscape for gastric cancer. Molecular characterization of patients will play a critical role in developing new agents, as well as in imple-menting new treatment options for this disease.

    2016-01-01

    Bladder cancer remains one of the most expensive cancers to treat in the United States due to the length of required treatment and degree of recurrence. In order to treat bladder cancer more effectively, targeted therapies are being investigated. In order to use targeted therapy in a patient, it is important to provide a genetic background of the patient. Recent advances in genome sequencing, as well as transcriptome analysis, have identified major pathway components altered in bladder cancer. The purpose of this review is to provide a broad background on bladder cancer, including its causes, diagnosis, stages, treatments, animal models, as well as signaling pathways in bladder cancer. The major focus is given to the PI3K/AKT pathway, p53/pRb signaling pathways, and the histone modification machinery. Because several promising immunological therapies are also emerging in the treatment of bladder cancer, focus is also given on general activation of the immune system for the treatment of bladder cancer.

    2015-09-01

    The widely used screening for prostate cancer with prostate specific antigen has resulted in identification of potentially lethal prostate cancers at a much more curable stage and has been associated with significant falls in prostate cancer mortality. In spite of the fact that prostate cancer is one of the deadliest malignancies in men, the advent of sensitive diagnostic testing has also resulted in detection of low risk cancers due to the high incidence of latent prostate cancer in aging men and prolonged natural history of the disease. This, in turn, has entailed the problem of cancer overdiagnosis and subsequent overtreatment. Approximately 6 times as many men will be diagnosed with the disease as will die from it. Active surveillance appeared as a response to the clearly documented risks of overdiagnosis and overtreatment of low risk prostate cancer for localized prostate cancer. It entails initial expectant management rather than immediate therapy, with 'curative-intent' treatment deferred until there is evidence that the patient is at an increased risk of disease progression. This approach attempts to balance the risks and side effects of overtreatment against the possibility of disease progression and lost opportunity for cure. A systematic literature review brings current knowledge on the subject.

    Cancer stem cells (CSCs) are a subpopulation of cancer cells with many clinical implications in most cancer types. One important clinical implication of CSCs is their role in cancer metastases, as reflected by their ability to initiate and drive micro and macro-metastases. The other important contributing factor for CSCs in cancer management is their function in causing treatment resistance and recurrence in cancer via their activation of different signalling pathways such as Notch, Wnt/β-catenin, TGF-β, Hedgehog, PI3K/Akt/mTOR and JAK/STAT pathways. Thus, many different therapeutic approaches are being tested for prevention and treatment of cancer recurrence. These may include treatment strategies targeting altered genetic signalling pathways by blocking specific cell surface molecules, altering the cancer microenvironments that nurture cancer stem cells, inducing differentiation of CSCs, immunotherapy based on CSCs associated antigens, exploiting metabolites to kill CSCs, and designing small interfering RNA/DNA molecules that especially target CSCs. Because of the huge potential of these approaches to improve cancer management, it is important to identify and isolate cancer stem cells for precise study and application of prior the research on their role in cancer. Commonly used methodologies for detection and isolation of CSCs include functional, image-based, molecular, cytological sorting and filtration approaches, the use of different surface markers and xenotransplantation. Overall, given their significance in cancer biology, refining the isolation and targeting of CSCs will play an important role in future management of cancer.

    2015-05-01

    Pancreatic cancer is a highly aggressive malignancy with limited treatment options. To improve survival for patients with pancreatic cancer, research has focused on other treatment modalities like adding biological modulators such as type-I interferons (IFNs). Type I IFNs (ie, IFN-α/IFN-β) have antiproliferative, antiviral, and immunoregulatory activities. Furthermore, they are able to induce apoptosis, exert cell cycle blocking, and sensitize tumor cells for chemo- and radiotherapy. A few years ago in vitro, in vivo, and several clinical trials have been described regarding adjuvant IFN-α therapy in the treatment of pancreatic cancer. Some studies reported a remarkable increase in the 2- and 5-year survival. Unfortunately, the only randomized clinical trial did not show a significant increase in overall survival, although the increased median survival implicated that some patients in the experimental group benefited from the adjuvant IFN-α therapy. Furthermore, encouraging in vitro and in vivo data points to a possible role for adjuvant IFN therapy. However, up till now, the use of IFNs in the treatment of pancreatic cancer remains controversial. This review, therefore, aims to describe, based on the available data, whether there is a distinct role for IFN therapy in the treatment of pancreatic cancer.

    2012-01-01

    Full Text Available Bladder carcinoma is the second most common malignancy of the urinary tract. Up to 85% of patients with bladder cancer are diagnosed with a tumor that is limited to the bladder mucosa (Ta, T1, and CIS. These stages are commonly termed as non-muscle-invasive bladder cancer (NMIBC. Although the treatment of NMIBC has greatly improved in recent years, there is a need for additional therapies when patients fail bacillus Calmette-Guérin (BCG and chemotherapeutic agents. We propose that bladder cancer may be an ideal target for oncolytic viruses engineered to selectively replicate in and lyse tumor cells leaving normal cells unharmed. In support of this hypothesis, here we review current treatment strategies for bladder cancer and their shortcomings, as well as recent advancements in oncolytic viral therapy demonstrating encouraging safety profiles and antitumor activity.

  9. Understanding the benefit of metformin use in cancer treatment

    Directory of Open Access Journals (Sweden)

    Goodwin Pamela J

    2011-04-01

    Full Text Available Abstract Biguanides have been developed for the treatment of hyperglycemia and type 2 diabetes. Recently, metformin, the most widely prescribed biguanide, has emerged as a potential anticancer agent. Epidemiological, preclinical and clinical evidence supports the use of metformin as a cancer therapeutic. The ability of metformin to lower circulating insulin may be particularly important for the treatment of cancers known to be associated with hyperinsulinemia, such as those of the breast and colon. Moreover, metformin may exhibit direct inhibitory effects on cancer cells by inhibiting mammalian target of rapamycin (mTOR signaling and protein synthesis. The evidence supporting a role for metformin in cancer therapy and its potential molecular mechanisms of action are discussed.

    2016-01-01

    Liver cancer is the most common malignancy of the digestive system with high death rate. Accumulating evidences suggests that many dietary natural products are potential sources for prevention and treatment of liver cancer, such as grapes, black currant, plum, pomegranate, cruciferous vegetables, French beans, tomatoes, asparagus, garlic, turmeric, ginger, soy, rice bran, and some edible macro-fungi. These dietary natural products and their active components could affect the development and progression of liver cancer in various ways, such as inhibiting tumor cell growth and metastasis, protecting against liver carcinogens, immunomodulating and enhancing effects of chemotherapeutic drugs. This review summarizes the potential prevention and treatment activities of dietary natural products and their major bioactive constituents on liver cancer, and discusses possible mechanisms of action.

    2011-01-01

    Renal transplantation is a standard procedure for end-stage renal disease today. Due to immunosuppressive drugs and increasing survival time after renal trans-plantation, patients with transplanted kidneys carry an increased risk of developing malignant tumors. In this case report, 3 patients with advanced rectal can-cer after renal transplantation for renal failure were treated with anterior resection or abdominoperineal resection plus total mesorectal excision, followed by adjuvant chemotherapy. One patient eventually died of metastasized cancer 31 mo after therapy, although his organ grafts functioned well until his death. The other 2 patients were well during the 8 and 21 mo follow-up periods after rectal resection. We therefore strongly argue that patients with advanced rectal cancer should receive standard oncology treatment, including opera-tion and adjuvant treatment after renal transplantation. Colorectal cancer screening in such patients appears justified.

  13. The Treatment of Breast Cancer Using Liposome Technology

    Directory of Open Access Journals (Sweden)

    Sarah Brown

    2012-01-01

    Full Text Available Liposome-based chemotherapeutics used in the treatment of breast cancer can in principle enhance the therapeutic index of otherwise unencapsulated anticancer drugs. This is partially attributed to the fact that encapsulation of cytotoxic agents within liposomes allows for increased concentrations of the drug to be delivered to the tumor site. In addition, the presence of the phospholipid bilayer prevents the encapsulated active form of the drug from being broken down in the body prior to reaching tumor tissue and also serves to minimize exposure of the drug to healthy sensitive tissue. While clinically approved liposome-based chemotherapeutics such as Doxil have proven to be quite effective in the treatment of breast cancer, significant challenges remain involving poor drug transfer between the liposome and cancerous cells. In this review, we discuss the recent advancements made in the development of liposome-based chemotherapeutics with respect to improved drug transfer for use in breast cancer therapy.

    The improved survival rates among patients with Hodgkin's lymphoma over the past few decades have come with increased incidence of second malignancies. One of the major concerns among female survivors is the significantly elevated risk of breast cancer that appears with extended follow-up. In this review, we include the published literature regarding the risk of breast cancer after irradiation for Hodgkin's lymphoma. We also present the possible long-term surveillance strategies and the optimal time to start screening these women. This could potentially help in early detection of secondary breast cancers and consequently improve outcomes. Furthermore, because of prior radiotherapy, the management of the breast cancer among this unique population has been controversial. We discuss the characteristics of breast cancer that occurs after Hodgkin's lymphoma and also treatment options that could be implemented.

    2015-01-01

    Full Text Available Objective: Cancer patients have reported that information plays a significant role in their capacity to cope with cancer and manage the consequences of treatment. This study was undertaken to identify the importance older adults receiving cancer treatment assign to selected types of cancer-related information, their satisfaction with the cancer-related information they received, and the barriers to effective information provision for this age group. Methods: This study was conducted in two phases with separate samples. Six hundred and eighty-four older cancer patients receiving treatment completed a standardized survey and 39 completed a semi-structured interview to gather perspectives about cancer-related information. Data were analyzed for 65-79 years and 80+ year groups. Results: Information topics about their medical condition, treatment options, and side effects of treatment were rated as most important by the older cancer patients. Women assigned a higher importance ratings than men to information overall (t = 4.8, P < 0.01. Although participants were generally satisfied with the information, they received many described challenges they experienced in communicating with health care professionals because of the medical language and fast pace of speaking used by the professionals. Conclusions: The older cancer patients in this study endorsed the same topics of cancer-related information as most important as has been reported in studies for other age groups. However, this older group recommended that, during their interactions with older individuals, health care professionals use fewer medical words, speak at a slower pace, and provide written information in addition to the actual conversation.

    Treatment of muscle-invasive bladder cancer in older patients is challenging. Definitive therapy of localized disease requires either surgery or radiation therapy, ideally combined with systemic chemotherapy. However, current population data suggest that less than half of patients older than age 70 are offered such treatments. We will review tools available to assess the fitness of older patients for surgery, alternatives, and tips for perioperative patient treatment.

    Full Text Available Abstract Background This exploratory prospective study evaluated women's responses to questions that asked them to describe how their body image and sexual functioning had changed since their breast cancer diagnosis to treatment. Methods A questionnaire concerning body image scale and various sexual problems experienced after diagnosis and treatment was anonymously completed by 120 women in the outpatient clinic of our hospital's Division of medical Oncology. To be eligible, subjects had to be sexually active and had histology proven breast cancer. They also had to have received treatment for breast cancer. Results 100% of participants have never spoken with their doctor about this subject. 84% of the participants continued sexual activity after treatment, but there was an increase in the incidence of sexual functioning problems which resulted in a slight reduction in the quality of their sex lives. 65% of the women experienced dyspareunia followed by lubrication difficulties (54% and the absence or reduction of sexual desire (48% and 64%, respectively while, 37% had lack of satisfaction (37%. Female orgasmic disorder and brief intercourse and arousal were reported respectively by 40% and 38% of the subjects. The sexual dysfunctions were absent before diagnosis and management of breast cancer in 91.5% subjects and of these 100% subjects complained of a deterioration of the symptomatology after the various treatments. 90% of the dysfunctions were observed after chemotherapy, 9% after surgery and 3% after radiotherapy; none of the subjects indicated the onset of dysfunctions to have been associated with hormonotherapy. 100% expressed not having received sufficient information about how the disease and treatment (including surgery might affect their sexual life. Conclusion Breast cancer and its treatment may result in significant difficulties with sexual functioning and sexual life. Addressing these problems is essential to improve the quality of

    Full Text Available Background: In recent years, cases of breast cancer have been on the rise in Vietnam. To date, there has been no study on the financial burden of the disease. This study estimates the direct medical cost of a 5-year treatment course for women with primary breast cancer in central Vietnam. Methods: Retrospective patient-level data from medical records at the Hue Central Hospital between 2001 and 2006 were analyzed. Cost analysis was conducted from the health care payers’ perspective. Various direct medical cost categories were computed for a 5-year treatment course for patients with breast cancer. Costs, in US dollars, discounted at a 3% rate, were converted to 2010 after adjusting for inflation. For each cost category, the mean, standard deviation, median, and cost range were estimated. Median regression was used to investigate the relationship between costs and the stage, age at diagnosis, and the health insurance coverage of the patients. Results: The total direct medical cost for a 5-year treatment course for breast cancer in central Vietnam was estimated at $975 per patient (range: $11.7–$3,955. The initial treatment cost, particularly the cost of chemotherapy, was found to account for the greatest proportion of total costs (64.9%. Among the patient characteristics studied, stage at diagnosis was significantly associated with total treatment costs. Patients at later stages of breast cancer did not differ significantly in their total costs from those at earlier stages however, but their survival time was much shorter. The absence of health insurance was the main factor limiting service uptake. Conclusion: From the health care payers’ perspective, the Government subsidization of public hospital charges lowered the direct medical costs of a 5-year treatment course for primary breast cancer in central Vietnam. However, the long treatment course was significantly influenced by out-of-pocket payments for patients without health insurance.

  4. Risk of acute myelogenous leukaemia and myelodysplasia following cancer treatment.

    van Leeuwen, F E

    1996-03-01

    Now that a substantial group of cancer patients has such a favourable prognosis, it has become increasingly important to evaluate the long-term complications of treatment. Of all late effects of treatment, secondary leukaemia is one of the most serious. Increased risk of AML has been observed both after RT and after CT; however, several types of CT have much stronger leukaemogenic properties than RT. Limited field radiation in the therapeutic dose range is associated with very little or no increased risk of leukaemia, which has been attributed to cell killing at the higher radiation doses. With respect to CT, two different syndromes of treatment-related AML have been recognized. Risk of alkylating agent-related AML is highest in the 5-10 year follow-up period and seems to decrease afterwards. This type of leukaemia is often preceded by MDS, and is characterized by deletions of chromosomes 5 and 7. Leukaemias related to treatment with the topoisomerase II inhibitors are characterized by a short induction period, presentation as myelomonocytic or monocytic leukaemia (rather than MDS) and balanced chromosomal translocations involving bands 11q23 and 21q22. This review addresses the risk of secondary AML and MDS following treatment of HD, NHL, testicular cancer, ovarian cancer, breast cancer and paediatric malignancies. In patients with HD, the risk of AML is higher with an increasing number of mechlorethamine-procarbazine-containing cycles, a greater number of CT episodes, and after splenectomy. The majority of data shows that RT does not add to the leukaemia risk from CT, but this issue is still surrounded by some controversy. ABV(D)-treated patients have a very low risk of AML. Generally, patients with NHL, testicular cancer and breast cancer experience much lower risk of AML than patients with HD. NHL and breast cancer treatment regimens with cumulative cyclophosphamide doses of 20 g or less do not confer an appreciable increase of AML. Recently, strongly increased

    1993-10-01

    Patients must be followed up closely after primary therapy for invasive breast cancer so that locoregional recurrences can be detected early. Once a recurrence has been detected, a thorough evaluation is indicated to exclude distant metastatic disease. If none is found, the patient may be a candidate for aggressive surgical intervention to render the patient disease-free. If distant disease is found, certain sites, such as the CNS or long bones, may warrant aggressive therapy because failure to treat these sites may lead to excessive morbidity. In most situations, patients with distant disease are treated with palliative measures. In selected instances, however, patients with metastatic breast cancer are candidates for aggressive intervention, including pulmonary or liver resection or high-dose chemotherapy in combination with autologous bone marrow transplantation, to rid the patient of the disease.

Each year, thousands die either because of disease progression or failure of treatment. Breast cancer is classified into different subtypes based on the molecular expression of estrogen receptor (ER, progesterone receptor, and/or human epidermal growth factor receptor 2 (HER2. These receptors represent important therapeutic targets either through monoclonal antibodies or through small-molecule inhibitors directed toward them. However, up to 40% of patients develop either a primary or a secondary resistance to the current treatments. Therefore, there is an urgent need for investigating new targets in order to overcome the resistance and/or enhance the current therapies. Cell cycle is altered in many human cancers, especially in breast cancer. Cyclin-dependent kinases (CDKs, especially CDK4 and CDK6, play a pivotal role in cell cycle progression that makes them potential targets for new promising therapies. CDK inhibition has shown strong antitumor activities, ranging from cytostatic antiproliferative effects to synergistic effects in combination with other antitumor drugs. In order to overcome the drawbacks of the first-generation CDK inhibitors, recently, new CDK inhibitors have emerged that are more selective to CDK4 and CDK6 such as palbociclib, which is the most advanced CDK4/6 inhibitor in trials. In preclinical studies, palbociclib has shown a very promising antitumor activity, especially against ERα+ breast cancer subtype. Palbociclib has gained world attention, and US the Food and Drug Administration has accelerated its approval for first-line treatment in combination with letrozole for the first-line systematic

  10. Maximizing outcomes in genitourinary cancers across the treatment continuum.

    2011-04-01

    Key controversies concerning the management of genitourinary cancers across the treatment continua were discussed at the second annual Interactive Genitourinary Cancer Conference (IGUCC) held in February 2010 in Athens, Greece. Prostate cancer is the most common form of cancer among western men and prevention strategies are needed. Trials evaluating 5α-reductase inhibitors have reported beneficial and clinically meaningful results, but uptake remains low for primary prostate cancer prevention. Prostate cancer detection programmes are also important as curative treatments for advanced disease are unavailable. Two large landmark randomized controlled trials reported conflicting results concerning screening efficacy and uncovered high levels of over-diagnosis and potential over-treatment. Tailored management strategies after diagnosis are important and predictive markers that distinguish between aggressive and indolent tumours are needed. The majority of newly diagnosed cases of prostate cancer are clinically localized. Active surveillance of favourable risk patients may be beneficial in the intermediate term, while an integrated approach of multi-modality therapy in patients with adverse features is recommended. The benefits of new technologies such as high-intensity focused ultrasound (HIFU) and robotic prostatectomy have not been established in prospective randomized trials vs current standards of care. A multidisciplinary approach is essential to evolving the management of advanced prostate cancer into a chronic disease paradigm. Docetaxel plus prednisone is the standard first-line chemotherapy for patients with metastatic castration-resistant prostate cancer (mCRPC), but the optimal timing of chemotherapy initiation has not been addressed in randomized clinical trials. Retrospective analyses suggest that asymptomatic patients with adverse prognostic factors for survival may also benefit from receiving chemotherapy. Bladder cancer is a common malignancy and the

    2004-01-01

    Metals and metal compounds have been used in medicine for several thousands of years. In this review we summarized the anti-cancer activities of the ten most active metals: arsenic, antimony, bismuth, gold, vanadium, iron, rhodium, titanium, gallium and platinum. The first reviewed metal, arsenic, presents the anomaly of displaying anti-cancer and oncogenic properties simultaneously. Some antimony derivatives, such as Sb2O3, salt (tartrate) and organic compounds, show interesting results. Bismuth directly affects Helicobacter pylori and gastric lymphoma; the effects of bismuth complexes of 6-mercaptopurine are promising. Gold(I) and (III) compounds show anti-tumour activities, although toxicity remains high. Research into the potential use of gold derivatives is still ongoing. Several derivatives of vanadium show anti-proliferative activity, but their toxicity must be overcome. Several pieces of evidence indicate that iron deprivation could be an excellent therapeutic approach; furthermore, it is synergistic with classic anti-cancer drugs. Rhodium belongs to the same group as platinum and it also presents interesting activity, but with the same nephrotoxicity. Several rhodium compounds have entered phase I clinical trials. In contrast to the platinum complexes, titanium derivatives showed no evidence of nephrotoxicity or myelotoxicity; titanocene dichloride is undergoing clinical trial. The anti-proliferative effect of gallium could be related to its competition with the iron atom; in addition a derivative appears to reverse the multidrug resistance. The last metal reviewed, platinum, has given some of the very best anti-cancer drugs. Four derivatives are used today in the clinic; their mechanism of action and of resistance are described.

    Full Text Available Chelates are used in cancer as cytotoxic agent, as radioactive agent in imaging studies and in radioimmunotherapy. Various chelates based on ruthenium, copper, zinc, organocobalt, gold, platinum, palladium, cobalt, nickel and iron are reported as cytotoxic agent. Monoclonal antibodies labeled with radioactive metals such as yttrium-90, indium-111 and iodine-131 are used in radioimmunotherapy. This review is an attempt to compile the use of chelates as cytotoxic drugs and in radioimmunotherapy.

    Lipoplatin is a new liposomal cisplatin formulation which seems to have these characteristics. Lipoplatin was shown to be effective in NSCLC both in phase 2 and phase 3 trials, with the same response rate of Cisplatin, a comparable overall survival but less toxicity. A new protocol aiming to elucidate the double capacity of Lipoplatin to act as a chemotherapeutic and angiogenetic agent in triple-negative breast cancer patients is upcoming.

    We present and analyze a mathematical model of the treatment of colorectal cancer using a system of nonlinear ordinary differential equations. The model describes the effectiveness of immunotherapy and chemotherapy for treatment of tumor cells and cancer stem cells (CSCs). The effects of CD8(+)T cells, natural killer cells, and interleukin proteins on tumor cells and CSCs under the influence of treatment are also illustrated. Using the method of localization of compact invariant sets, we present conditions on treatment parameters to guarantee a globally attracting tumor clearance state. Numerical simulations using estimated parameters from the literature are included to showcase various global dynamics of the model.

    Cervical cancer is one of the most common cancers in women worldwide. The outcome of patients with metastatic cervical cancer is poor. We reviewed the relevant literature concerning the treatment and diagnosis of metastatic cervical cancer. There are two types of metastasis related to different treatments and survival rates: hematogenous metastasis and lymphatic metastasis. Patients with hematogenous metastasis have a higher risk of death than those with lymphatic metastasis. In terms of diagnosis, fluoro-2-deoxy-D-glucose positron emission tomography (FDG-PET) and PET-computed tomography are effective tools for the evaluation of distant metastasis. Concurrent chemoradiotherapy and subsequent chemotherapy are well-tolerated and efficient for lymphatic metastasis. As for lung metastasis, chemotherapy and/or surgery are valuable treatments for resistant, recurrent metastatic cervical cancer and chemoradiotherapy may be the optimal choice for stage IVB cervical cancer. Chemotherapy and bone irradiation are promising for bone metastasis. A better survival is achieved with multimodal therapy. Craniotomy or stereotactic radiosurgery is an optimal choice combined with radiotherapy for solitary brain metastases. Chemotherapy and palliative brain radiation may be considered for multiple brain metastases and other organ metastases.

    The development of novel therapeutic approaches for cancer therapy is important, especially for tumors that have poor response or develop resistance to standard chemotherapy and radiation. We discovered that noninvasive radiofrequency (RF) fields can affect cancer cells but not normal cells, inhibit progression of tumors in mice, and enhance the anticancer effects of chemotherapy. However, it remains unclear what physiological and molecular mechanisms this treatment induces inside cells. Here, we studied the effect of RF treatment on mitochondria in human pancreatic cancer cells. The morphology of mitochondria in cells was studied via electron microscopy. The alteration of mitochondrial membrane potential (Δψ) was accessed using a Mitotracker probe. The respiratory activity of mitochondria was evaluated by analyzing changes in oxygen consumption rates determined with a Mito Stress Test Kit. The production of intracellular reactive oxygen species was performed using flow cytometry. The colocalization of mitochondria and autophagosome markers in cells was performed using fluorescence immunostaining and confocal microscopy analysis. RF fields treatment changed the morphology of mitochondria in cancer cells, altered polarization of the mitochondrial membrane, substantially impaired mitochondrial respiration, and increased reactive oxygen species production, indicating RF-induced stress on the mitochondria. We also observed frequent colocalization of the autophagosome marker LC3B with the mitochondrial marker Tom20 inside cancer cells after RF exposure, indicating the presence of mitochondria in the autophagosomes. This suggests that RF-induced stress can damage mitochondria and induce elimination of damaged organelles via autophagy. RF treatment impaired the function of mitochondria in cancer cells. Therefore, mitochondria can represent one of the targets of the RF treatment. © 2014 American Cancer Society.

    2009-01-01

    According to the 2008 guidelines on colorectal cancer, whether preoperative therapy is indicated for rectal cancer should be judged based on the T and N categories. A few centres limit the indication for preoperative radio(chemo)therapy to patients with tumours that, according to magnetic resonance tomography (MRT), extend to the fascia mesorectalis or are 1 mm or less away from it - so-called circumferential resection margin-positive or CRM-positive tumours. Omitting preoperative therapy for MRT CRM-negative tumours is, however, a matter that still requires further study in clinical trials. The high rate of distant metastases continues to be a problem. Assuming that pathohistological complete remission (pCR) is a predictive marker of long-term disease-free survival after neoadjuvant radiochemotherapy, attempts are now being undertaken to intensify the neoadjuvant therapy. Phase II trials show improved pCR rates by combining the preoperative radiation with the double combinations oxaliplatin or irinotecan plus infusional or oral 5-FU (capecitabine). In the case of limited T1 rectal cancer without further risk factors, transanal local excision can be used.

    In Brazil, cancer has become one of the major public health problems. An estimate by the Health Ministry showed that 466,430 people had the disease in the country in 2008. The prostate cancer is the second largest death cause among men. The National Institute of Cancer estimated the occurrence of 50,000 new cases for 2009. Some of these patients are treated with Brachytherapy, using Iodine-125 seeds. By this technique, small seeds with Iodine-125, a radioactive material, are implanted in the prostate. The advantages of radioactive seed implants are the preservation of healthy tissues and organs near the prostate, besides the low rate of impotence and urinary incontinence. The Energy and Nuclear Research Institute - IPEN, which belongs to the Nuclear Energy National Commission - CNEN, established a program for the development of the technique and production of Iodine-125 seeds in Brazil. The estimate for the 125-Iodine seeds demand is of 8,000 seeds/month and the laboratory to be implanted will need this production capacity. The purpose of this paper is to explain the project status and show some data about the seeds used in the country. The project will be divided in two phases: technological development of a prototype and a laboratory implementation for the seeds production. (author)

  19. Heat Shock Proteins, Autoimmunity, and Cancer Treatment

    Directory of Open Access Journals (Sweden)

    Stuart K. Calderwood

    2012-01-01

    Full Text Available Heat shock proteins (HSPs have been linked to the therapy of both cancer and inflammatory diseases, approaches that utilize contrasting immune properties of these proteins. It would appear that HSP family members Hsp60 and Hsp70, whether from external sources or induced locally during inflammation, can be processed by antigen-presenting cells and that HSP-derived epitopes then activate regulatory T cells and suppress inflammatory diseases. These effects also extend to the HSP-rich environments of cancer cells where elevated HSP concentrations may participate in the immunosuppressive tumor milieu. However, HSPs can also be important mediators of tumor immunity. Due to their molecular chaperone properties, some HSPs can bind tumor-specific peptides and deliver them deep into the antigen-processing pathways of antigen-presenting cells (APCs. In this context, HSP-based vaccines can activate tumor-specific immunity, trigger the proliferation and CTL capabilities of cancer-specific CD8+ T cells, and inhibit tumor growth. Further advances in HSP-based anticancer immunotherapy appear to involve improving the properties of the molecular chaperone vaccines by enhancing their antigen-binding properties and combating the immunosuppressive tumor milieu to permit programming of active CTL capable of penetrating the tumor milieu and specifically targeting tumor cells.

    An improvement in pancreatic cancer treatment represents an urgent medical goal. Late diagnosis and high intrinsic resistance to conventional chemotherapy has led to a dismal overall prognosis that has remained unchanged during the past decades. Increasing knowledge about the molecular pathogenesis of the disease has shown that genetic alterations, such as mutations of K-ras, and especially epigenetic dysregulation of tumor-associated genes, such as silencing of the tumor suppressor p16(ink4a), are hallmarks of pancreatic cancer. Here, we describe genes that are commonly affected by epigenetic dysregulation in pancreatic cancer via DNA methylation, histone acetylation or miRNA (microRNA) expression, and review the implications on pancreatic cancer biology such as epithelial-mesenchymal transition, morphological pattern formation, or cancer stem cell regulation during carcinogenesis from PanIN (pancreatic intraepithelial lesions) to invasive cancer and resistance development. Epigenetic drugs, such as DNA methyltransferases or histone deactylase inhibitors, have shown promising preclinical results in pancreatic cancer and are currently in early phases of clinical development. Combinations of epigenetic drugs with established cytotoxic drugs or targeted therapies are promising approaches to improve the poor response and survival rate of pancreatic cancer patients.

    Full Text Available OBJECTIVE: Oral health can affect a patient’s general health and quality of life. Given the increase in breast cancer survival rates, investigations of factors influencing the quality of life of survivors have gained importance. Therefore, the objective of our study was to characterize oral health in postmenopausal breast cancer survivors. METHODS: We conducted a matched case-control study. Forty-eight women who survived breast cancer (age 62.1±9.1 years and 48 healthy controls (age 61.8±8.6 years were included. For each case and control, a complete oral evaluation chart was completed. RESULTS: The prevalence of chronic periodontal disease was 98% in breast cancer survivors and 87% in controls. The breast cancer survivors had a median of 16 remaining teeth, whereas controls had a median of 22 remaining teeth (p = 0.03. The percentage of sites with gingival bleeding was 16.05% (0-100% in breast cancer survivors and 0% (0-72% in controls (p = 0.04. CONCLUSION: Chronic periodontal disease and tooth loss were highly prevalent in postmenopausal breast cancer survivors. To improve survivors’ quality of life, a preventive oral health evaluation should be available prior to cancer treatment.

  3. Dietary Bioactive Diallyl Trisulfide in Cancer Prevention and Treatment

    2017-07-01

    Full Text Available Bioactive dietary agents have been shown to regulate multiple cancer hallmark pathways. Epidemiologic studies have linked consumption of Allium vegetables, such as garlic and onions, to decreased incidence of cancer. Diallyl trisulfide (DATS, a bioactive compound derived from Allium vegetables, has been investigated as an anti-cancer and chemopreventive agent. Preclinical studies provide ample evidence that DATS regulates multiple cancer hallmark pathways including cell cycle, apoptosis, angiogenesis, invasion, and metastasis. DATS has been shown to arrest cancer cells at multiple stages of the cell cycle with the G2/M arrest being the most widely reported. Additionally, increased pro-apoptotic capacity as a result of regulating intrinsic and extrinsic apoptotic pathway components has been widely reported following DATS treatment. Invasion, migration, and angiogenesis represent emerging targets of DATS and support its anti-cancer properties. This review summarizes DATS mechanisms of action as an anti-cancer and chemopreventive agent. These studies provide rationale for future investigation into its use as a cancer chemopreventive agent.

  4. Systemic treatment for hereditary cancers: a 2012 update.

    2013-04-01

    The history of specific therapy for hereditary tumors dates back to mid 1980s and involves a number of reports demonstrating regression of familial colon polyps upon administration of sulindac. Virtually no clinical studies on other hereditary cancer types were available until the year 2009, when Byrski et al. presented the data on unprecedented sensitivity of BRCA1-associated breast malignancies to cisplatin. This breakthrough has revived interest to the treatment of cancer in germ-line mutation carriers. Recent trials and clinical observations have confirmed the efficacy of platinating agents and PARP inhibitors in BRCA1/2-driven breast, ovarian and pancreatic carcinomas. Pegylated liposomal doxorubicin may be considered as a promising treatment option for BRCA1/2-related ovarian cancer after the failure of platinum-containing therapy. Several novel drugs have been recently introduced in the management of rare familial tumor syndromes. Vandetanib, a low-molecular weight RET kinase inhibitor, demonstrated substantial efficacy in the treatment of hereditary and sporadic medullary thyroid cancer. Vismodegib, an inhibitor of SMO oncoprotein, caused regression of basal-cell carcinomas in patients with Gorlin syndrome. Down-regulation of mTOR kinase by everolimus has been successfully used for the therapy of subependymal giant-cell astrocytomas in patients with tuberous sclerosis. The achievements in the prevention, diagnostics and treatment of hereditary cancers may serve as an excellent example of triumph of translational medicine.

    Oropharyngeal cancer is a diagnosis which means a change in life and even after successful treatment a tremendous reduction in the quality of life. Aim of this study is to analyse the health-related quality of life in patients with oropharyngeal cancer dependent on different treatment options. Charts of 256 patients treated for oropharyngeal cancer between 1997 and 2007 were analysed in a retrospective study. Inclusion criteria for this study has been fulfilled by 98 patients, 82 of these completed the study. Therefore, standardised questionnaires (EORTC QLQ-C30 und EORTC QLQ-H&N35) have been used and 2 groups were compared: patients with primary radiochemotherapy (pRCT) vs. patients treated by an operation and adjuvant radiation. Most of the health-related quality of life domains in our patients were significantly reduced compared to the general population. There have been just very few significant differences in the quality of life domains in between the 2 groups. Health-related quality of life after treatment of oropharyngeal cancer is significantly compromised for these patients compared to the general population, but there have been no obvious differences depending on the compared treatment options. Only regarding the items "physical and cognitive functioning" patients after primary radiochemotherapy showed significantly better results and thus a better quality of life, despite the fact, that this group has a significantly advanced cancer stadium. © Georg Thieme Verlag KG Stuttgart · New York.

  6. Endoscopic mucosectomy: an alternative treatment for superficial esophageal cancer.

    Science.gov (United States)

    Lambert, R

    2000-01-01

    Recent trends in the management of superficial esophageal cancer consist of improved detection, pretherapeutic staging and reliable criteria for curative endoscopic therapy. The endoscopic treatment is legitimate when the cancer is at an early stage, intra-epithelial or microinvasive (m1 or m2) and N0. Submucosal cancer should not be treated with a curative intent by endotherapy. Concerning squamous cell cancer, the oriental and occidental pathologists include high-grade dysplasia in the same group as intramucosal cancer. The distinction is however maintained for adenocarcinoma in the Barrett's esophagus. Indications of endoscopic rather than surgical treatment rely on: (1) the small size of the tumor (not more than 2 cm in diameter); (2) the endoscopic morphology in the type 0 of the Japanese classification with the flat subtypes IIa and IIb rather than type IIc--there is high risk of submucosal invasion for the polypoid (type I) or ulcerated superficial cancer (type III); and (3) the endoscopic ultrasound staging, with confirmed integrity of the hyperechoic submucosal layer. The high-frequency (20 MHz) miniprobe is preferred to the standard (7.5 MHz) instrument. The elective procedure for tumor eradication is endoscopic mucosectomy. The technique is associated with a 6.8% risk of severe complications (hemorrhage or perforation) and a recurrence rate of 3%-7%. The 5-year survival rate is similar to that of surgery (over 80%). In the small group of patients with superficial esophageal cancer (less than 10% of the disease) endoscopic treatment may now be proposed in about 30% of cases, surgery is preferred for submucosal cancer and for neoplasia with a large surface. Areas of high-grade dysplasia in the Barrett's esophagus offer a new and increasing sector of indications. The concurrent endoscopic procedure of destruction--photodynamic therapy--is preferred for the destruction of lesions with poorly delineated limits.

  7. Treatment of Lung Cancer in Medically Compromised Patients.

    2016-01-01

    Outcomes for patients with lung cancer have been improved substantially through the integration of surgery, radiation, and systemic therapy for patients with early-stage disease. Meanwhile, advances in our understanding of molecular mechanisms have substantially advanced our treatment of patients with advanced lung cancer through the introduction of targeted therapies, immune approaches, improvements in chemotherapy, and better supportive care. However, the majority of these advances have occurred among patients with good functional status, normal organ function, and with the social and economic support systems to be able to benefit most from these treatments. The aim of this article is to bring greater attention to management of lung cancer in patients who are medically compromised, which remains a major barrier to care delivery. Impaired performance status is associated with poor outcomes and correlates with the high prevalence of cachexia among patients with advanced lung cancer. CT imaging is emerging as a research tool to quantify muscle loss in patients with cancer, and new therapeutics are on the horizon that may provide important adjunctive therapy in the future. The benefits of cancer therapy for patients with organ failure are poorly understood because of their exclusion from clinical trials. The availability of targeted therapy and immunotherapy may provide alternatives that may be easier to deliver in this population, but clinical trials of these new agents in this population are vital. Patients with lower socioeconomic status are disproportionately affected by lung cancer because of higher rates of tobacco addiction and the impact of socioeconomic status on delay in diagnosis, treatment, and outcomes. For all patients who are medically compromised with lung cancer, multidisciplinary approaches are particularly needed to evaluate these patients and to incorporate rapidly changing therapeutics to improve outcomes.

    2017-04-15

    Current treatment regimens for gastric cancer are not adequate. Cancer stem cells (CSCs) may be a key driving factor for growth and metastasis of this tumor type. In contrast to the conventional clonal evolution hypothesis, CSCs can initiate tumor formation, self-renew, and differentiate into tumor-propagating cells. Because gastric cancer can originate from CSCs, it is necessary to review current targets of signaling pathways for CSCs in gastric cancer that are being studied in clinical trials. These pathways are known to regulate the self-renewal and differentiation process in gastric CSCs. A better understanding of the clinical results of trials that target gastric CSCs will lead to better outcomes for patients with gastric cancer. Cancer 2017;123:1303-1312. © 2017 The Authors.

    This article seeks to understand the viewpoint of cancer patients about the disease process and the therapeutic procedures that they experience. Cancer treatments provoke a series of physical and emotional consequences in patients. Thus, patients undergo a restructuring of life and establish mechanisms to "take care of themselves." The methodology used was an ethnographic approach through interviews, field notes and participant observation. The ethnographic approach revealed how these women being given conventional treatment in a given hospital create shared care technologies based on sociability.

    Because cancer of the male breast is rare knowledge about its biology and behavior is essentially due to a compilation of pooled experiences. Hence, a continued report of cases appears to be important. Therefore a retrospective review of patients suffering from male breast cancer was carried out. Twenty-four evaluable cases were analyzed. Eight patients (1 patient with bilateral Stage I carcinoma was included) were in Stage I, 7 in Stage II, 2 in Stage IIIa, 4 in Stage IIIb, and 3 in Stage IV. Of 23 patients who were treated with mastectomy, 22 had modified radical mastectomy and postoperative irradiation to the chest wall as well as to the peripheral lymphatic areas in most cases. One patient underwent radical mastectomy. Another patient had an excision biopsy only, followed by irradiation. One of 24 patients received tamoxifen; another received cyclophosphamide, methotrexate, 5-fluorouracil, prednisone (CMF) regimen in an adjuvant setting. Local recurrence developed in one of 23 (4%) patients treated with mastectomy and radiation therapy to the chest wall and peripheral lymphatics. Four (17%) patients developed distant metastases. The 5-year overall survival (Kaplan-Maier) was 90% for the entire group, 100% for patients in Stage I-III disease, and 60% in Stage IV disease (P = < 0.005). As observed in former reports the stage of disease at initial presentation seems to be a parameter that significantly contributes to survival in male breast cancer patients. To what extent improved local control by adequate local therapy, such as surgery and postoperative radiotherapy, may improve overall survival remains to be discussed. (orig.)

  11. What does cancer treatment look like in consumer cancer magazines? An exploratory analysis of photographic content in consumer cancer magazines.

    Phillips, Selene G; Della, Lindsay J; Sohn, Steve H

    2011-04-01

    In an exploratory analysis of several highly circulated consumer cancer magazines, the authors evaluated congruency between visual images of cancer patients and target audience risk profile. The authors assessed 413 images of cancer patients/potential patients for demographic variables such as age, gender, and ethnicity/race. They compared this profile with actual risk statistics. The images in the magazines are considerably younger, more female, and more White than what is indicated by U.S. cancer risk statistics. The authors also assessed images for visual signs of cancer testing/diagnosis and treatment. Few individuals show obvious signs of cancer treatment (e.g., head scarves, skin/nail abnormalities, thin body types). Most images feature healthier looking people, some actively engaged in construction work, bicycling, and yoga. In contrast, a scan of the editorial content showed that nearly two thirds of the articles focus on treatment issues. To explicate the implications of this imagery-text discontinuity on readers' attention and cognitive processing, the authors used constructs from information processing and social identity theories. On the basis of these models/theories, the authors provide recommendations for consumer cancer magazines, suggesting that the imagery be adjusted to reflect cancer diagnosis realities for enhanced message attention and comprehension.

    This study presents a technoeconomic analysis of wheat straw densification in Canada's prairie province of Manitoba as an integral part of biomass-to-cellulosic-ethanol infrastructure. Costs of wheat straw bale and pellet transportation and densification are analysed, including densification plant profitability. Wheat straw collection radius increases nonlinearly with pellet plant capacity, from 9.2 to 37km for a 2-35tonnesh(-1) plant. Bales are cheaper under 250km, beyond which the cheapest feedstocks are pellets from the largest pellet plant that can be built to exploit economies of scale. Feedstocks account for the largest percentage of variable costs. Marginal and average cost curves suggest Manitoba could support a pellet plant up to 35tonnesh(-1). Operating below capacity (75-50%) significantly erodes a plant's net present value (NPV). Smaller plants require higher NPV break-even prices. Very large plants have considerable risk under low pellet prices and increased processing costs.

    2010-07-01

    Responsibility for the operation and maintenance of provincial dams has been transferred, at the province's initiative, to Manitoba Infrastructure and Transportation (MIT). MIT used the 2007 CDA guidelines as reference in the development of a dam safety program for provincial dams in response to the lack of provincial legislation for the regulation and management of dams in Manitoba. This paper presented the work of the MIT to develop and implement a management system, with emphasis on the planning and implementation elements. MIT focused on both the prioritization of work and the implementation of an inspection program. To develop a prioritization scheme, a risk assessment was performed with the estimation of risk based on the impact of an event occurring and integrating the quality of the controls in place. Multiple account analysis (MAA) was also used to develop a second prioritization plan.

    2013-03-01

    Full Text Available OBJECTIVES: Colon cancer is the third most common in the top cancer incidence list in Europe. In Europe 212,000 patients die every year due to colon cancer. In Turkey 120,000-130,000 new cancer patients are diagnosed every year, 7.1% of whom are diagnosed to have developed colon cancer. Metastases will occur in up to 50% of the patients who are newly diagnosed. Survival appears to be further prolonged to more than 20 months with new pharmaceuticals; however, these new pharmaceuticals increase the total cost of care. The aim of this study is to estimate the cost implications of new colon cancer treatment options for Turkey.METHODS: Gazi University Hospital treatment protocols for colon cancer treatment were used. Cost of FUFA (5 FU/LV, FOLFIRI, FOLFOX, bevacizumab/FUFA, bevacizumab/FOLFIRI, bevacizumab/FOLFOX, irinotecan and irinotecan/cetixumab protocols were calculated. The cost of combination of protocols were calculated depending on a Markov analysis. The exchange rate was US$ 1 for TL 1.5.RESULTS: Depending on the life expectancy the lowest total cost was established by FUVA (US$ 5,359. It was followed by FOLFIRI then FOLFOX and FOLFOX, US$ 14,144 and US$ 16,553, respectively. The lowest cost for each week of life expectancy was established by FUVA with US$ 98.CONCLUSIONS: Only FUFA, FOLFIRI followed by FOLFIX, FOLFIRI/bevacizumab then FOLFOX then cetuximab, FOLFOX/bevacizumab then irinotecan then cetuximab/irinotecan and FOLFIRI/bevacizumab then FOLFOX then cetuximab/irinotecan were under the cost effectiveness curve. In addition no treatments ICER was under the WHO`s threshold for Turkey, except FOLFIRI then FOLFOX compared with FUVA.

    To optimize breast cancer care, several organizations have crafted guidelines to define best practices for treating breast cancer. In addition to recommended therapies, 'timeliness of treatment' has been proposed as a quality metric. Our study evaluates time to surgical treatment and its effect on overall survival (OS). The National Cancer Data Base (NCDB) was used to identify women diagnosed with invasive breast cancer between 2004 and 2012. Time from diagnosis to surgical treatment was calculated and grouped according to predetermined time intervals. Univariate and multivariate Cox proportional hazard models were used to assess patient and treatment factors related to OS. Overall, 420,792 patients initially treated with surgery were identified. Increased time to surgical treatment >12 weeks was associated with decreased OS [hazard ratio (HR) 1.14, 95 % confidence interval (CI) 1.09-1.20]. When stratified by pathologic stage, stage I patients treated at 8 to HR 1.07, 95 % CI 1.02-1.13) and >12 weeks (HR 1.19, 95 % CI 1.11-1.28), as well as stage II patients treated at >12 weeks (HR 1.16, 95 % CI 1.08-1.25), had decreased OS compared with patients treated at <4 weeks. Other variables associated with decreased survival were treatment at a community cancer program, Medicaid or Medicare insurance, Black race, increasing age, mastectomy, moderately and poorly differentiated tumor grade, increasing T and N stage, and higher Charlson Index Group. The survival benefit of expedited time to initial surgical treatment varies by stage and appears to have the greatest impact in early-stage disease. Prior to establishing standard metrics, further quantification of the impact on patient outcomes is needed.

    Full Text Available Patrick J Richard, Ramesh Rengan Department of Radiation Oncology, University of Washington, Seattle, WA, USA Abstract: The oligometastatic disease theory was initially described in 1995 by Hellman and Weichselbaum. Since then, much work has been performed to investigate its existence in many solid tumors. This has led to subclassifications of stage IV cancer, which could redefine our treatment approaches and the therapeutic outcomes for this historically “incurable” entity. With a high incidence of stage IV disease, non-small-cell lung cancer (NSCLC remains a difficult cancer to treat and cure. Recent work has proven the existence of an oligometastatic state in NSCLC in terms of properly selecting patients who may benefit from aggressive therapy and experience long-term overall survival. This review discusses the current treatment approaches used in oligometastatic NSCLC and provides the evidence and rationale for each approach. The prognostic factors of many trials are discussed, which can be used to properly select patients for aggressive treatment regimens. Future advances in both molecular profiling of NSCLC to find targetable mutations and investigating patient selection may increase the number of patients diagnosed with oligometastatic NSCLC. As this disease entity increases, it is of utmost importance for oncologists treating NSCLC to be aware of the current treatment strategies that exist and the potential advantages/disadvantages of each.
