    Full Text Available Background . Complementary and alternative medicine (CAM practices for cancer have become popular among oncology patients. An increasing interest in alternative medicine can be explained by the inefficiency of conventional treatment, dissatisfaction with treating patients like objects, and the will to use all available treatment methods. Objectives . The authors assessed how often patients use CAM methods, and which of them are most popular. Material and methods . The study was conducted in Military Hospital no. 109 and the Independent Public Clinical Hospital no. 1 in Szczecin among 100 chemotherapy patients. This survey-based study was performed using an original questionnaire. Results. Most respondents (68% did not use alternative methods to fight the disease. The most popular treatment methods were: herbal medicine (50%, alternative medicine preparations (38% and diet (25%, and the least common: hypnosis (3% and aromatherapy (3%. Analyzed sociodemographic factors had no effects on a choice of a CAM method. Patients obtained information about CAM methods mainly from the Internet (40%, medical staff (37% and literature (31%. Conclusions . 1. Using CAM by patients receiving chemotherapy for neoplasms is quite a common phenomenon. 2. CAM were more often chosen by women. Neither the duration of the disease nor sociodemographic data had effects on making the decision to use CAM methods. 3. The most popular CAM were: herbal medicine, alternative medicine preparations, and diet. 4. Cancer patients should receive special support from nurses and doctors as well as other members of the therapeutic team. Oncology patients should never be left on their own so that they were forced to seek help and support in therapies unconfirmed by scientific investigation.

    There is accumulating clinical evidence that chemotherapeutic agents induce neurological side effects, including memory deficits and mood disorders, in cancer patients who have undergone chemotherapeutic treatments. This review focuses on chemotherapy-induced neurodegeneration and hippocampal dysfunctions and related mechanisms as measured by in vivo and in vitro approaches. These investigations are helpful in determining how best to further explore the causal mechanisms of chemotherapy-induced neurological side effects and in providing direction for the future development of novel optimized chemotherapeutic agents.

    2016-01-01

    Prior to the recent therapeutic advances, chemotherapy was the mainstay of treatment options for advanced-stage melanoma. A number of studies have investigated various chemotherapy combinations in order to expand on the clinical responses achieved with single-agent dacarbazine, but these have not demonstrated an improvement in overall survival. Similar objective responses were observed with the combination of carboplatin and paclitaxel as were seen with single-agent dacarbazine. The combination of chemotherapy and immunotherapy, known as biochemo-therapy, has shown high clinical responses; however, biochemo-therapy has not been shown to improve overall survival and resulted in increased toxicities. In contrast, palliation and long-term responses have been observed with localized treatment with isolated limb perfusion or infusion in limb-isolated disease. Although new, improved therapeutic options exist for first-line management of advanced-stage melanoma, chemotherapy may still be important in the palliative treatment of refractory, progressive, and relapsed melanoma. We review the various chemotherapy options available for use in the treatment and palliation of advanced-stage melanoma, discuss the important clinical trials supporting the treatment recommendations, and focus on the clinical circumstances in which treatment with chemotherapy is useful.

    Metastatic gastric cancer remains a non-curative disease.Palliative chemotherapy has been demonstrated to prolong survival without quality of life compromise. Many single-agents and combinations have been confirmed to be active in the treatment of metastatic disease. Objective response rates ranged from 10-30% for single-agent therapy and 30-60% for polychemotherapy. Results of phase Ⅱ and Ⅲ studies are reviewed in this paper as well as the potential efficacy of new drugs. For patients with localized disease, the role of adjuvant and neoadjuvant chemotherapy and radiation therapy is discussed.Most studies on adjuvant chemotherapy failed to demonstrate a survival advantage, and therefore, it is not considered as standard treatment in most centres. Adjuvant immunochemotherapy has been developed fundamentally in Korea and Japan. A meta-analysis of phase Ⅲ trials with OK-432 suggested that immunochemotherapy may improve survival of patients with curatively resected gastric cancer. Based on the results of US Intergroup 0116study, postoperative chemoradiation has been Accepted as standard care in patients with resected gastric cancer in North America. However, the results are somewhat confounded by the fact that patients underwent less than a recommended D1 lymph node dissection and the pattern of recurrence suggested a positive effect derived from local radiotherapy without any effect on micrometastatic disease.Neoadjuvant chemotherapy or chemoradiation therapy remains experimental, but several phase Ⅱstudies are showing promising results. Phase Ⅲ trials are needed.

    There are many reasons that lead to failure of cancer chemotherapy. Cancer has the ability to become resistant to many different types of drugs. Increased efflux of drug, enhanced repair/increased tolerance to DNA damage, high antiapoptotic potential, decreased permeability and enzymatic deactivation allow cancer cell survive the chemotherapy. Treatment can lead to the death of most tumor cells (drug-sensitive), but some of them (drug-resistant) survive and grow again. These tumor cells may arise from stem cells. There are many studies describing human experiments with multidrug resistance, especially in breast cancer. Unfortunately, studies of canine or feline ABC super family members are not as extensive as in human or mice and they are limited to several papers describing PGP in mammary cancer, cutaneous mast cell tumors and lymphoma. Multidrug resistance is one of the most significant problems in oncology today. The involvement of many different, not fully recognized, mechanisms in multidrug resistance of cancer cells makes the development of effective methods of therapy very difficult. Understanding the mechanisms of drug resistance in cancer cells may improve the results of treatment. This review article provides a synopsis of all aspects that refer to cancer cell resistance to antitumor drugs.

    2008-11-01

    The use of chemotherapy to treat cancer began at the start of the 20th century with attempts to narrow the universe of chemicals that might affect the disease by developing methods to screen chemicals using transplantable tumors in rodents. It was, however, four World War II-related programs, and the effects of drugs that evolved from them, that provided the impetus to establish in 1955 the national drug development effort known as the Cancer Chemotherapy National Service Center. The ability of combination chemotherapy to cure acute childhood leukemia and advanced Hodgkin's disease in the 1960s and early 1970s overcame the prevailing pessimism about the ability of drugs to cure advanced cancers, facilitated the study of adjuvant chemotherapy, and helped foster the national cancer program. Today, chemotherapy has changed as important molecular abnormalities are being used to screen for potential new drugs as well as for targeted treatments.

  3. Interstitial pneumonitis following intrapleural chemotherapy

    2009-02-01

    Full Text Available Abstract Background Mucinous neoplasms within the abdomen may disseminate by direct extension through the diaphragm to involve the pleural space. Treatment of this condition is by parietal and visceral pleurectomy followed by hyperthermic intrapleural chemotherapy. Case presentation In this case report a patient developed persistent right upper lobe interstitial pneumonitis and progressive parenchymal fibrosis following intrapleural chemotherapy treatment with mitomycin C and doxrubicin. The condition persisted until death 28 months later. Death was from progressive intraabdominal disease with intestinal obstruction and sepsis associated with progressive pulmonary parenchymal disease. The right pleural space disease did not recur. Conclusion This manuscript is the first case report describing interstitial pneumonitis and lung fibrosis following intrapleural chemotherapy. Since pulmonary toxicity from chemotherapy is a dose-dependent phenomenon, dose reduction of intrapleural as compared to intraperitoneal hyperthermic chemotherapy may be necessary.

    Directory of Open Access Journals (Sweden)

    M. Yu. Fedyanin

    2016-01-01

    Full Text Available Metronomic chemotherapy implies the regular use of cytotoxic agents in doses much smaller than the maximum tolerable doses for a long time. Preclinical experiments show that this treatment option has a many-sided (antiangiogenic, immunostimulating, and direct cytotoxic effect on tumor. Moreover, this approach has gained the widest acceptance in treating patients with metastatic breast cancer in clinical practice. By taking into account the high activity of angiogenesis in colon cancer progression, it is interesting to study the impact of metronomic chemotherapy regimens for this nosological entity as well. This literature review considers not only the history of metronomic chemotherapy, the mechanisms of action, and a range of drugs having an antitumor effect in the metronomic regimens, but also analyzes clinical trials of metronomic chemotherapy regimens in patients with metastatic colon cancer.

    2012-02-01

    Lymphangioleiomyomatosis is a rare cause of pneumothorax in women. We present the case of a 48-year-old woman with lymphangioleiomyomatosis, who had never had a pneumothorax prior to commencing chemotherapy for breast cancer. During chemotherapy she developed 3 pneumothoraces and 2 episodes of pneumomediastinum. We suggest that the pneumothoraces were caused by the chemotherapy. To our knowledge, this is the first reported case of chemotherapy triggering pneumothoraces in a woman with lymphangioleiomyomatosis.

    Full Text Available We present the case of a congenital localised sacrococcygeal primitive neuroectodermal tumor treated aggressively with surgical resection and modified age-appropriate adjuvant chemotherapy. The conventional combination chemotherapy of vincristine, adriamycin, cyclophosphamide, ifosfamide and etoposide was modified to a regimen including vincristine, adriamicin, cyclophosphamide and actinomycin in order to minimise the predicted toxicity in this age group. Adjuvant "induction" chemotherapy commenced at 4 weeks of age and consisted of four cycles of vincristine, adriamycin and cyclophosphamide at 50%, 75%, 75% and 100% of recommended doses (vincristine 0.05 mg/kg, adriamycin 0.83 mg/kg daily × 2, cyclophosphamide 40 mg/kg at 3-weekly intervals. This was followed by four cycles of "maintenance" chemotherapy with vincristine (0.025 mg/kg, actinomycin (0.025 mg/kg and cyclophosphamide (36 mg/kg at full recommended doses. Cardioxane at a dose of 16.6 mg/kg was infused immediately prior to the adriamycin. Our patient is thriving at 19 months out from end of treatment.

    Full Text Available Khaled A Elsaid,1,2 Steven Garguilo,1 Christine M Collins2 1Department of Pharmaceutical Sciences, School of Pharmacy, MCPHS University, Boston, MA, 2Pharmacy Services, Rhode Island Hospital, Providence, RI, USA Abstract: Chemotherapy drugs are characterized by low therapeutic indices and significant toxicities at clinically prescribed doses, raising serious issues of drug safety. The safety of the chemotherapy medication use process is further challenged by regimen complexity and need to tailor treatment to patient status. Errors that occur during chemotherapy prescribing are associated with serious and life-threatening outcomes. Computerized provider order entry (CPOE systems were shown to reduce overall medication errors in ambulatory and inpatient settings. The adoption of chemotherapy CPOE is lagging due to financial cost and cultural and technological challenges. Institutions that adopted infusional or oral chemotherapy electronic prescribing modified existing CPOE systems to allow chemotherapy prescribing, implemented chemotherapy-specific CPOE systems, or developed home-grown chemotherapy electronic prescribing programs. Implementation of chemotherapy electronic prescribing was associated with a significant reduction in the risk of prescribing errors, most significantly dose calculation and adjustment errors. In certain cases, implementation of chemotherapy CPOE was shown to improve the chemotherapy use process. The implementation of chemotherapy CPOE may increase the risk of new types of errors, especially if processes are not redesigned and adapted to CPOE. Organizations aiming to implement chemotherapy CPOE should pursue a multidisciplinary approach engaging all stakeholders to guide system selection and implementation. Following implementation, organizations should develop and use a risk assessment process to identify and evaluate unanticipated consequences and CPOE-generated errors. The results of these analyses should serve to

    Nausea and vomiting are two of the most troubling side effects patients experience during chemotherapy. While newly available treatments have improved our ability to manage nausea and vomiting, anticipatory and delayed nausea and vomiting are still a major problem for patients receiving chemotherapy. Many cancer patients will delay or refuse future chemotherapy treatments and contemplate stopping chemotherapy altogether because of their fear of experiencing further nausea and vomiting. The purpose of this article is to provide an overview of the patho-psychophysiology of chemotherapy-induced nausea and vomiting and the recommended guidelines for treatment.

    Function and integrity disorders of the oral cavity fall into the most frequent complication of the chemotherapy of leucemias, malignant lymphomas and solid tumors. Complications associated with cancer chemotherapy can be direct ones, resulting from the toxic action of antineoplastic agents on the proliferative lining of the mouth, or indirect, as a result of myelosuppression and immunosuppression. The most frequent oral complications associated with cancer chemotherapy are mucositis, infection and bleeding. The principles of prevention and management of oral complications during cancer chemotherapy are considered in this paper.

    Accumulating evidence indicates that the innate and adaptive immune systems make a crucial contribution to the antitumour effects of conventional chemotherapy-based and radiotherapy-based cancer treatments. Moreover, the molecular and cellular bases of the immunogenicity of cell death that is induced by cytotoxic agents are being progressively unravelled, challenging the guidelines that currently govern the development of anticancer drugs. Here, we review the immunological aspects of conventional cancer treatments and propose that future successes in the fight against cancer will rely on the development and clinical application of combined chemo- and immunotherapies.

  5. Chemotherapy and Dietary Phytochemical Agents

    Directory of Open Access Journals (Sweden)

    Katrin Sak

    2012-01-01

    Full Text Available Chemotherapy has been used for cancer treatment already for almost 70 years by targeting the proliferation potential and metastasising ability of tumour cells. Despite the progress made in the development of potent chemotherapy drugs, their toxicity to normal tissues and adverse side effects in multiple organ systems as well as drug resistance have remained the major obstacles for the successful clinical use. Cytotoxic agents decrease considerably the quality of life of cancer patients manifesting as acute complaints and impacting the life of survivors also for years after the treatment. Toxicity often limits the usefulness of anticancer agents being also the reason why many patients discontinue the treatment. The nutritional approach may be the means of helping to raise cancer therapy to a new level of success as supplementing or supporting the body with natural phytochemicals cannot only reduce adverse side effects but improve also the effectiveness of chemotherapeutics. Various plant-derived compounds improve the efficiency of cytotoxic agents, decrease their resistance, lower and alleviate toxic side effects, reduce the risk of tumour lysis syndrome, and detoxify the body of chemotherapeutics. The personalised approach using various phytochemicals provides thus a new dimension to the standard cancer therapy for improving its outcome in a complex and complementary way.

    2015-01-01

    BACKGROUND: Neoadjuvant chemotherapy has proven valuable in several tumors, but it has not been elucidated in colon cancer. The present phase II trial addressed the issue in high-risk patients selected by computed tomography (CT) scan. MATERIAL AND METHODS: Patients with resectable colon cancer...... mutational status received three cycles of capecitabine 2000 mg/m(2) days 1-14 q3w and oxaliplatin 130 mg iv day 1 q3w.

    Chemotherapy-induced mucositis is a clinically important and sometimes dose-limiting toxicity of cancer treatment, including standard-dose chemotherapy, high-dose chemotherapy and chemoradiotherapy. Consequently, dose reductions or treatment delays resulting from mucositis may impair treatment effectiveness. Symptoms are oral mucositis, dysphagia, abdominal pain and diarrhea, depending on the affected site. Although the underlying pathobiology of oral mucositis has been considerably elucidated over the past decade, there are few interventions for the prevention or treatment validated by randomized trials. The most commonly accepted intervention is basic oral care. Diarrhea is most common in patients treated with irinotecan and in some cases, life-threatening. No definitive interventions for the prevention of diarrhea exist, but there is evidence that loperamide and octreotide are effective for chemotherapy-induced diarrhea. In future, there is a need for well designed trials, preferably including a placebo or no treatment control, validating more effective interventions for managing chemotherapy- induced mucositis.

    2016-01-01

    Chemotherapy of leprosy over the past 70 years has passed through several phases, from sulfones, to clofazimine, and to highly bactericidal drugs like rifampicin. The use particularly of the more potent drugs in effective combinations and the development of standard multidrug therapy regimens have made a huge difference in the successful treatment of leprosy as well as in reducing tremendously the prevalence of leprosy globally. A major contributing factor to development of better drugs and drug combinations has been the introduction of the mouse footpad model to evaluate the in vivo activity of drugs against Mycobacterium leprae. The World Health Organization has recommended multidrug therapy, which has been used to treat more than 15 million patients in the last 30 years and has set an excellent record with regard to its very high rate of cure, very low occurrence of relapse, and very rare occurrence of drug resistance.

    Full Text Available Colorectal cancer is one of the leading causes of cancer incidence and mortality. In 2008 inRussian Federation55 719 new cases of colorectal cancer were diagnosed and 37 911 patients died of this disease. A significant progress was achieved in metastatic colorectal cancer treatment during the last decades. A lot of treatment options became available: from 5-fluoruracil monotherapy to combined treatment treatment schemes including surgery. A group of patients with isolated liver metastases was distinguished, who can achieve 5-year survival rate of 40 % after systemic treatment and surgery. Today, based on clinical data and molecular analysis, we come close to individualized treatment of this patient group. In this literature review results of metastatic colorectal cancer chemotherapy are being analyzed and rational treatment tactic is proposed based on therapy goals.

    Despite treatment advances, nausea and vomiting, especially anticipatory nausea and vomiting, delayed nausea and vomiting and nausea alone, are still the most common, expected and feared side effects among patients receiving chemotherapy. Of the 70 to 80% of cancer patients who experience chemotherapy-induced nausea and vomiting many will delay or refuse future chemotherapy treatments and contemplate stopping all treatments because of fear of further nausea and vomiting. The purpose of this chapter is to provide an overview of the patho-psychophysiology of CINV, the recommended guidelines for standard treatment, and highlight newer targeted treatment approaches.

    The Oncology Nursing Society and the American Society of Clinical Oncology have established guidelines for the safe and effective use of chemotherapeutic medications in the acute and outpatient care settings. A review of literature was performed to determine the safe and effective administration of chemotherapy in the home environment. The administration of oral and intravenous chemotherapy in the home has become a common intervention for patients being treated for cancer based on patient preference, cost-effectiveness of healthcare delivery, and increasing demand for oncology services. Home healthcare nurses can greatly impact the management of adverse effects of chemotherapy in the home, increasing the quality of life and improving patient outcomes.

    The authors reviewed 24 cerebellar medulloblastoma patients treated at Keio University to determine usefulness of combined chemotherapy including platinum derivatives (cisplatin, carboplatin) as the induction and maintenance treatment. All patients underwent radical surgery and craniospinal irradiation. Ten received adjuvant chemotherapy other than platinum derivatives (mainly with nitrosourea compounds), five were treated by induction and maintenance chemotherapy including platinum derivatives, and nine patients did not undergo chemotherapy. The progression-free survival rate of patients treated with platinum derivatives was better than that of patients treated with other modes of chemotherapy and also that of patients who did not receive chemotherapy. The results were especially good in the case of four patients treated with maintenance chemotherapy consisting of carboplatin and etoposide, two of whom had been free from relapse beyond the risk period of Collins. The occurrences of toxicity in maintenance chemotherapy with carboplatin and etoposide were limited to transient leucopenia. The present study indicates combined chemotherapy including platinum derivatives benefits patients with medulloblastoma, and could be useful, especially as maintenance treatment. (author)

    Aim: To review the computed tomography (CT), magnetic resonance imaging (MRI) and cholangiographic findings of chemotherapy-induced sclerosing cholangitis (CISC). Methods: Between January 1995 and December 2004, 11 patients in the endoscopic retrograde cholangiography database were identified with CISC. Twelve CT, four MRI, 69 endoscopic and nine antegrade cholangiographic studies in these patients were reviewed. Serial change in appearance and response to endoscopic treatment were recorded. Results: CISC showed segmental irregular biliary dilatation with strictures of proximal extrahepatic bile ducts. The distal 5 cm of common bile duct was not affected in any patient. CT and MRI findings included altered vascular perfusion of one or more liver segments, liver metastases or peritoneal carcinomatosis. Biliary strictures needed repeated stenting in 10 patients (mean: every 4.7 months). Cirrhosis (n = 1) or confluent fibrosis (n = 0) were uncommon findings. Conclusion: CISC shares similar cholangiographic appearances to primary sclerosing cholangitis (PSC). Unlike PSC, biliary disease primarily involved ducts at the hepatic porta rather than intrahepatic ducts. Multiphasic contrast-enhanced CT or MRI may show evidence of perfusion abnormalities, cavitary liver lesions, or metastatic disease.

    Full Text Available While chemotherapeutic agents have yielded relative success in the treatment of cancer, patients are often plagued with unwanted and even debilitating side-effects from the treatment which can lead to dose reduction or even cessation of treatment. Common side effects (symptoms of chemotherapy include (i cognitive deficiencies such as problems with attention, memory and executive functioning; (ii fatigue and motivational deficit; and (iii neuropathy. These symptoms often develop during treatment but can remain even after cessation of chemotherapy, severely impacting long-term quality of life. Little is known about the underlying mechanisms responsible for the development of these behavioral toxicities, however, neuroinflammation is widely considered to be one of the major mechanisms responsible for chemotherapy-induced symptoms. Here, we critically assess what is known in regards to the role of neuroinflammation in chemotherapy-induced symptoms. We also argue that, based on the available evidence neuroinflammation is unlikely the only mechanism involved in the pathogenesis of chemotherapy-induced behavioral toxicities. We evaluate two other putative candidate mechanisms. To this end we discuss the mediating role of damage-associated molecular patterns (DAMPs activated in response to chemotherapy-induced cellular damage. We also review the literature with respect to possible alternative mechanisms such as a chemotherapy-induced change in the bioenergetic status of the tissue involving changes in mitochondrial function in relation to chemotherapy-induced behavioral toxicities. Understanding the mechanisms that underlie the emergence of fatigue, neuropathy, and cognitive difficulties is vital to better treatment and long-term survival of cancer patients.

    Full Text Available Chemotherapy is the first line treatment in management of many cancers, both for cure and palliation; hence it’s crucial to minimize the unpleasant side effects of chemotherapy to increase tolerability to chemotherapy. Most of the conventional anti cancer drugs are emetogenic. Patients receiving chemotherapy experience different degrees of nausea and vomiting depending on the emetogenic potential of the anti cancer drugs given and the patient characteristics. With a better understanding of the pathophysiology, distinct phases of chemotherapy-induced nausea and vomiting (CINV i.e., acute emesis, delayed emesis and anticipatory emesis have been identified. Identification of various mediators has led to the development of different drugs acting through different mechanisms which are useful in the prevention and treatment of CINV. Serotonin receptor three (5-HT3 antagonists, corticosteroids and neurokinin type one receptor (NK-1 antagonists are of proven usefulness and have wide therapeutic indexes in the prevention of CINV. Other drugs like dopamine receptor antagonists & benzodiazepines are not routinely used because of their narrow therapeutic index. Practice guidelines for prevention of CINV will not only improve patient’s tolerability to chemotherapy & wellbeing, but also decrease hospital stay and overall cost of treatment of the patient.

    Chronic calorie restriction has been known for decades to prevent or retard cancer growth, but its weight-loss effect and the potential problems associated with combining it with chemotherapy have prevented its clinical application. Based on the discovery in model organisms that short term starvation (STS or fasting) causes a rapid switch of cells to a protected mode, we described a fasting-based intervention that causes remarkable changes in the levels of glucose, IGF-I and many other proteins and molecules and is capable of protecting mammalian cells and mice from various toxins, including chemotherapy. Because oncogenes prevent the cellular switch to this stress resistance mode, starvation for 48 hours or longer protects normal yeast and mammalian cells and mice but not cancer cells from chemotherapy, an effect we termed Differential Stress Resistance (DSR). In a recent article, 10 patients who fasted in combination with chemotherapy, reported that fasting was not only feasible and safe but caused a reduction in a wide range of side effects accompanied by an apparently normal and possibly augmented chemotherapy efficacy. Together with the remarkable results observed in animals, these data provide preliminary evidence in support of the human application of this fundamental biogerontology finding, particularly for terminal patients receiving chemotherapy. Here we briefly discuss the basic, pre-clinical, and clinical studies on fasting and cancer therapy.

    Cancer therapies can be associated with significant central nervous system (CNS) toxicity. While radiation-induced brain damage has been long recognized both in pediatric and adult cancer patients, CNS toxicity from chemotherapy has only recently been acknowledged. Clinical studies suggest that the most frequent neurotoxic adverse effects associated with chemotherapy include memory and learning deficits, alterations of attention, concentration, processing speed and executive function. Preclinical studies have started to shed light on how chemotherapy targets the CNS both on cellular and molecular levels to disrupt neural function and brain plasticity. Potential mechanisms include direct cellular toxicity, alterations in cellular metabolism, oxidative stress, and induction of pro-inflammatory processes with subsequent disruption of normal cellular and neurological function. Damage to neural progenitor cell populations within germinal zones of the adult CNS has been identified as one of the key mechanisms by which chemotherapy might exert long-lasting and progressive neurotoxic effects. Based on the important role of the hippocampus for maintenance of brain plasticity throughout life, several experimental studies have focused on the study of chemotherapy effects on hippocampal neurogenesis and associated learning and memory. An increasing body of literature from both animal studies and neuroimaging studies in cancer patients suggests a possible relationship between chemotherapy induced hippocampal damage and the spectrum of neurocognitive deficits and mood alterations observed in cancer patients. This review aims to briefly summarize current preclinical and neuroimaging studies that are providing a potential link between the neurotoxic effects of chemotherapy and hippocampal dysfunction, highlighting challenges and future directions in this field of investigation.

    Chiasmal gliomas are rare tumors occurring predominantly in childhood. Their optimal treatment is still controversial. In the past only neurosurgeons (performing partial or subtotal removal of the tumor, biopsy or shunting procedure in hydrocephalus) and radiotherapeutists participated in their treatment. In the middle of the eighties there was only a single article dealing with chemotherapy of these tumors (Rosenstock, 1985). Since that time there was an increased number of articles about harmful effects of radiotherapy on the developing child's brain. Neurosurgeons are aware that they will not solve this problem alone. During the past 7 years we have observed gradual retreat from radiotherapy and an inclination to combined chemotherapy of the chiasmal gliomas in children. The author has been engaged in the research of this clinical entity for more than 10 years and he offers to readers a summary of the contemporary knowledge about chemotherapy of chiasmal gliomas in children. Despite the fact that there is lacking experience with long-term survivors after chemotherapy, which is extremely important especially in this disease, the preliminary short-term results of combined chemotherapy of chiasmal gliomas in children are promising. Rapid development of chemistry and pharmacology in the last few years is promising for the discovery of further, more effective anti-tumor drugs. Their new combinations could improve present non-satisfactory results of treatment of chiasmal gliomas in children. (Ref. 25.)

    Full Text Available SUMMARY Introduction The successful development of chemotherapy enabled a fertilitysparing treatment for patients with trophoblastic neoplasia. After disease remission, the outcome of a subsequent pregnancy becomes a great concern for these women. Objective To analyze existing studies in the literature that describe the reproductive outcomes of patients with trophoblastic neoplasia treated with chemotherapy. Method Systematic review was performed searching for articles on Medline/ Pubmed, Lilacs and Cochrane Library databases, using the terms “gestational trophoblastic disease” and “pregnancy outcome”. Results A total of 18 articles were included. No evidence of decreased fertility after chemotherapy for trophoblastic neoplasia was observed. The abortion rates in patients who conceived within 6 months after chemotherapy was higher compared to those who waited longer. Some studies showed increased rates of stillbirth and repeat hydatidiform moles. Only one work showed increased congenital abnormalities. Conclusion The pregnancies conceived after chemotherapy for trophoblastic neoplasia should be followed with clinical surveillance due to higher rates of some pregnancy complications. However, studies in the literature provide reassuring data about reproductive outcomes of these patients.

    The development of curative chemotherapy regimens for the treatment of Hodgkin's lymphoma (HL) is one of the true success stories in oncology. Most patients diagnosed with HL today can be cured. The major task remaining before us is curing as many patients as possible with their initial therapeutic approach while minimizing the acute toxicities and limiting the lifetime risks of important secondary events such as cardiovascular complications and secondary malignancies. In the 40 years since DeVita et al. developed the mechlorethamine, vincristine, procarbazine, and prednisone chemotherapy regimen, we have learned a great deal about risk stratification to minimize treatment-related toxicity. Positron emission tomography may further assist us in reducing radiation treatment without compromising cures. This review will discuss the development of the chemotherapy regimens used in the management of early and advanced stage HL and the advantages and disadvantages of their use in combination with radiation therapy.

    Psychological distress is a common problem among patients with cancer, yet it mostly goes unreported and untreated. This study examined the association of a psycho-educational intervention with the psychological distress levels of breast cancer and cervical cancer patients undergoing chemotherapy. The design of the study was quasi-experimental, pretest-posttest design with a comparison group. One hundred patients at a cancer hospital in Jakarta, Indonesia, completed Distress Thermometer screening before and after chemotherapy. Fifty patients in the intervention group were given a psycho-educational video with positive reappraisal, education and relaxation contents, while receiving chemotherapy. Patients who received the psycho-educational intervention had significantly lower distress levels compared with those in the control group. Routine distress screening, followed by distress management and outcome assessment, is needed to improve the wellbeing of cancer patients.

    2015-01-01

    Breast cancer is the leading cause of cancer among women worldwide and the most common cancer in China. Many factors influence the treatment strategy for metastatic breast cancer (MBC). Chemotherapy should be administered to patients with hormone receptor-negative tumors, symptomatic visceral metastasis, and a short disease-free interval. Sequential single-agent chemotherapy has similar efficacy as combination agents in terms of overall survival and quality of life. Anthracyclines are the cornerstone of first-line treatment for MBC, and taxanes represent the second treatment option after resistance. When progression or intolerable toxicity occurs after optimal treatment, the alternative treatments include capecitabine, vinorel-bine, and gemcitabine. Ixabepilone and eribulin are relatively new effective single agents. A combination of cytotoxic agents for patients with rapid clinical progression can further improve the overall response rate and time to progression compared to single-agent treatment. For patients with MBC who were pretreated with anthracyclines in the neoadjuvant/adjuvant setting, a taxane-containing regimen such as docetaxel plus capecitabine or gemcitabine plus paclitaxel should be administered. Platinum-based therapies such as cisplatin or carboplatin have a role in the treatment of triple-negative breast cancer. Meanwhile, the efficacy of the addition of targeted drugs such as iniparib, bevacizumab, and cetuximab to chemotherapy remains unproven. Maintenance chemotherapy is routinely recommended in clinical practice at present. Patients who were previously treated with paclitaxel and gemcitabine have better progression-free and overall survival with maintenance chemotherapy according to a Korean phase Ⅲ clinical trial. Sequential maintenance treatment with capecitabine monotherapy after capecitabine-based combination chemotherapy (X-based X) appears favorable based on a series of domestic studies.

  14. Oculomotor Deficits after Chemotherapy in Childhood.

    Directory of Open Access Journals (Sweden)

    Einar-Jón Einarsson

    Full Text Available Advances in the diagnosis and treatment of pediatric malignancies have substantially increased the number of childhood cancer survivors. However, reports suggest that some of the chemotherapy agents used for treatment can cross the blood brain barrier which may lead to a host of neurological symptoms including oculomotor dysfunction. Whether chemotherapy at young age causes oculomotor dysfunction later in life is unknown. Oculomotor performance was assessed with traditional and novel methods in 23 adults (mean age 25.3 years, treatment age 10.2 years treated with chemotherapy for a solid malignant tumor not affecting the central nervous system. Their results were compared to those from 25 healthy, age-matched controls (mean age 25.1 years. Correlation analysis was performed between the subjective symptoms reported by the chemotherapy treated subjects (CTS and oculomotor performance. In CTS, the temporal control of the smooth pursuit velocity (velocity accuracy was markedly poorer (p<0.001 and the saccades had disproportionally shorter amplitude than normal for the associated saccade peak velocity (main sequence (p = 0.004, whereas smooth pursuit and saccade onset times were shorter (p = 0.004 in CTS compared with controls. The CTS treated before 12 years of age manifested more severe oculomotor deficits. CTS frequently reported subjective symptoms of visual disturbances (70%, unsteadiness, light-headedness and that things around them were spinning or moving (87%. Several subjective symptoms were significantly related to deficits in oculomotor performance. To conclude, chemotherapy in childhood or adolescence can result in severe oculomotor dysfunctions in adulthood. The revealed oculomotor dysfunctions were significantly related to the subjects' self-perception of visual disturbances, dizziness, light-headedness and sensing unsteadiness. Assessments of oculomotor function may, thus, offer an objective method to track and rate the level of

    The two combination chemotherapy regimens FOLFIRINOX and gemcitabine plus nab-paclitaxel represent major breakthroughs in the management of metastatic pancreatic cancer. Both regimens showed unprecedented survival advantage in the setting of front-line therapy. However, their application for treatment of patients in the community is challenging because of significant toxicities, thus limiting potential benefits to a narrow population of patients. Modifications to the dose intensity or schedule of those regimens improve their tolerability, while likely retaining survival advantage over single-agent chemotherapy. Newer strategies to optimize these two active regimens in advanced pancreatic cancer are being explored that can help personalize treatment to individual patients.

    Full Text Available The management of retinoblastoma (RB has dramatically changed over the past two decades from previous radiotherapy methods to current chemotherapy strategies. RB is a remarkably chemotherapy-sensitive tumor. Chemotherapy is currently used as a first-line approach for children with this malignancy and can be delivered by intravenous, intra-arterial, periocular, and intravitreal routes. The choice of route for chemotherapy administration depends upon the tumor laterality and tumor staging. Intravenous chemotherapy (IVC is used most often in bilateral cases, orbital RB, and as an adjuvant treatment in high-risk RB. Intra-arterial chemotherapy (IAC is used in cases with group C or D RB and selected cases of group E tumor. Periocular chemotherapy is used as an adjunct treatment in eyes with group D and E RB and those with persistent/recurrent vitreous seeds. Intravitreal chemotherapy is reserved for eyes with persistent/recurrent vitreous seeds. In this review, we describe the various forms of chemotherapy used in the management of RB. A database search was performed on PubMed, using the terms "RB," and "treatment," "chemotherapy," "systemic chemotherapy," "IVC," "IAC," "periocular chemotherapy," or "intravitreal chemotherapy." Relevant English language articles were extracted, reviewed, and referenced appropriately.

    Objective:The expression of tumor biomarkers may change after chemotherapy. However, whether secreted protein acidic and rich in cysteine (SPARC) expression changes atfer chemotherapy in gastric cancer (GC) is unclear. hTis study investigated the inlfuence of chemotherapy on SPARC expression in GC. Methods:Immunohistochemistry was used to analyze SPARC expression in 132 GC cases (including 54 cases with preoperative chemotherapy and 78 cases without preoperative chemotherapy). SPARC expression of postoperative specimens with and without preoperative chemotherapy was assessed to analyze the inlfuence of chemotherapy on SPARC expression. Results:SPARC was highly expressed in GC compared with the desmoplastic stroma surrounding tumor cells and noncancerous tissues. High SPARC expression was correlated with invasion depth, lymph node, and TNM stage. After chemotherapy, a lower proportion of high SPARC expression was observed in patients with preoperative chemotherapy than in the controls. For 54 patients with preoperative chemotherapy, gross type, histology, depth of invasion, lymph node, TNM stage, and SPARC expression were related to overall survival. Further multivariate analysis showed that lymph node, histology, and SPARC expression atfer chemotherapy were independent prognostic factors. Conclusion:SPARC expression may change after chemotherapy in GC. SPARC expression should be reassessed for patients with GC atfer chemotherapy.

    OBJECTIVE To investigate the role of maintenance chemotherapy on stage Ⅲ ovarian carcinoma.METHODS A retrospective analysis was conducted of 47 stage Ⅲ ovarian carcinoma patients with clinical complete remission after first-line chemotherapy. Among these patients, 21 cases were treated with maintenance chemotherapy, while the other 26 cases were free of treatment until progression. The 2 groups were compared with respect to progression-free survival (PFS) and overall survival(OS).RESULTS The median PFS and OS were not significantly different between the 2 groups. For those patients, in a subgroup of suboptimal surgery (residual disease >2 cm), the median PFS was 110 weeks and 56 weeks and the median OS was 223 weeks and 157 weeks for the maintenance and non-treated respectively. Both PFS and OS values favoured the maintenance group, P=0.004 and P=0.015 respectively. In a subgroup of optimal surgery (residual disease ≤2 cm), the differences were not significant.CONCLUSION Patients with stage Ⅲ ovarian carcinoma with clinical complete remission may benefit from maintenance chemotherapy, if the residual disease is >2 cm. To those with a residual disease ≤2 cm, the maintenance chemotherapy maybe of no value. So "individualized maintenance chemotherapy" should be conducted in the clinical setting.

  15. Progress in Personalizing Chemotherapy for Bladder Cancer

    Directory of Open Access Journals (Sweden)

    James S. Chang

    2012-01-01

    Full Text Available Platinum-based chemotherapy is commonly used for the treatment of locally advanced and metastatic bladder cancer. However, there are currently no methods to predict chemotherapy response in this disease setting. A better understanding of the biology of bladder cancer has led to developments of molecular biomarkers that may help guide clinical decision making. These biomarkers, while promising, have not yet been validated in prospective trials and are not ready for clinical applications. As alkylating agents, platinum drugs kill cancer cells mainly through induction of DNA damage. A microdosing approach is currently being tested to determine if chemoresistance can be identified by measuring platinum-induced DNA damage using highly sensitive accelerator mass spectrometry technology. The hope is that these emerging strategies will help pave the road towards personalized therapy in advanced bladder cancer.

  16. Using Epigenetic Therapy to Overcome Chemotherapy Resistance.

    Science.gov (United States)

    Strauss, Julius; Figg, William D

    2016-01-01

    It has been known for decades that as cancer progresses, tumors develop genetic alterations, making them highly prone to developing resistance to therapies. Classically, it has been thought that these acquired genetic changes are fixed. This has led to the paradigm of moving from one cancer therapy to the next while avoiding past therapies. However, emerging data on epigenetic changes during tumor progression and use of epigenetic therapies have shown that epigenetic modifications leading to chemotherapy resistance have the potential to be reversible with epigenetic therapy. In fact, promising clinical data exist that treatment with epigenetic agents can diminish chemotherapy resistance in a number of tumor types including chronic myelogenous leukemia, colorectal, ovarian, lung and breast cancer. The potential for epigenetic-modifying drugs to allow for treatment of resistant disease is exciting and clinical trials have just begun to evaluate this area.

  17. Neoadjuvant chemotherapy for invasive bladder cancer.

    Sonpavde, Guru; Sternberg, Cora N

    2012-04-01

    Neoadjuvant cisplatin-based combination chemotherapy is an established standard for resectable muscle-invasive bladder cancer, a disease with a pattern of predominantly distant and early recurrences. Pathologic complete remission appears to be an intermediate surrogate for survival when employing combination chemotherapy. Moreover, baseline host and tumor tissue studies may enable the discovery of biomarkers predictive of activity. The neoadjuvant setting also provides a window of opportunity to evaluate novel biologic agents or rational combinations of biologic agents to obtain a signal of biologic activity. The residual tumor after neoadjuvant therapy may be exploited to study the mechanism of action and resistance. Cisplatin-ineligible patients warrant the evaluation of tolerable neoadjuvant regimens. Given that bladder cancer is characterized by initial localized presentation in the vast majority of cases, the paradigm of neoadjuvant therapy may expedite the development of novel systemic agents.

    With recent advances in medical and orthopedic oncology, radiation therapy and single- or multiple-agent perioperative chemotherapy are currently applied as an essential part of the multidisciplinary treatment to improve disease-free and overall survival of patients with primary and metastatic bone and soft tissue tumors. However, these treatments have led to unwanted complications. A better understanding of the effects of various antineoplastic agents on bone, soft tissue, and organs may provide the basis for the more efficacious use of antiproliferative drugs when fracture healing or allograft incorporation is required. This knowledge may also provide a rationale for concurrent treatment with drugs that protect against or compensate for adverse effects in osseous repair resulting from chemotherapy.

    Glanders is a zoonotic infection inducing acute forms of the disease (pneumonia, sepsis) in humans and animals under certain conditions, which even with the use of modern chemotherapy have unfavourable prognosis. Insufficient of efficacy of antibiotics with in vitro low MIC for planktonic bacterial suspension of Burkholderia mallei in chemotherapy of acute forms of glanders was due to the capacity of the pathogen for intracellular survival and formation of biofilms. Under such conditions the susceptibility of B. mallei to antibiotics lowered by several orders of magnitude. Chemotherapy of the glanders acute forms in animals usually provided only an increase of the lifespan, while among the survivors there was recorded a high relapse rate. More favourable outcomes were observed with the use of in vitro effective antibiotics in the form of clathrate compounds or especially liposomal forms. In the experiments with golden hamsters the survival rate reached 100% in 1000 Dlm infection even with the treatment onset by meropenem liposomal form 48 hours after the infection. Chemotherapeutics in the liposomal form significantly lowered resistance of B. mallei in both the experiments with a suspension of planktonic organisms and the use of bacteria interned in eukaryotic cells (Tetrahymena pyriformis).

    2001-07-01

    Recombinant human thrombopoietin (rhTPO) is a full-length glycosylated molecule that has been under evaluation in the setting of chemotherapy-induced myelosuppression. It has been shown to be a potent stimulator of platelet production in cancer patients when administered prior to chemotherapy. The peak platelet response to a single dose of rhTPO is observed around day 12, and is accompanied by a significant increase in the number of mature megakaryocytes in bone marrow. Consistent with this biologic effect, rhTPO administered postchemotherapy has been shown to be effective in attenuating severe thrombocytopenia induced by carboplatin, which produces a late platelet nadir. Early clinical experience with a regimen that produces an early nadir, however, such as AI (doxorubicin [Adriamycin] and ifosfamide [Ifex]), suggests that administration of rhTPO both prior to and following chemotherapy might be important to reduce thrombocytopenia severity. Treatment with rhTPO in these clinical trials has been well tolerated with a favorable safety profile. Randomized clinical trials have been initiated to determine further the importance of schedule in the prevention and treatment of severe thrombocytopenia in cancer patients.

    2016-01-01

    Chemotherapy using the taxanes, docetaxel and cabazitaxel, remains an important therapeutic option in metastatic castration-resistant prostate cancer (CRPC). However, despite the survival benefits afforded by these agents, the survival increments are modest and resistance occurs universally. Efforts to overcome resistance to docetaxel by combining with biologic agents have heretofore been unsuccessful. Indeed, resistance to these taxanes is also associated with cross-resistance to the antiandrogen drugs, abiraterone and enzalutamide. Here, we discuss the various mechanisms of resistance to chemotherapy in metastatic CRPC and the potential role of emerging regimens and agents in varying clinical phases of development.

    Hypersensitivity reactions are increasingly prevalent, although underrecognized and underreported. Platins induce immunoglobulin E-mediated sensitization; taxenes and some monoclonal antibodies can induce reactions at first exposure. Severe hypersensitivity can preclude first-line therapy. Tryptase level at the time of a reaction is a useful diagnostic tool. Skin testing provides a specific diagnosis. Newer tests are promising diagnostic tools to help identify patients at risk before first exposure. Safe management includes rapid drug desensitization. This review provides information regarding the scope of hypersensitivity and anaphylactic reactions induced by chemotherapy and biological drugs, as well as diagnosis, management, and treatment options.

    Objective:To explore the clinical efifcacy and safety of rituximab combined with chemotherapy and single chemotherapy for diffuse large B cell lymphoma (DLBCL). Methods:A total of 97 patients with DLBCL were selected. Patients treated by single chemotherapy were designed as control group, while those by rituximab combined with chemotherapy as observational group. All patients were treated for at least 4 cycles. The short-term and long-term efifcacy and related adverse reactions of 2 groups were observed. Results:The rate of complete remission (CR) in observational group was signiifcantly higher than in control group (χ2=4.6589,P=0.0309). However, there was no signiifcant difference in objective remission rate (ORR) between 2 groups (P=0.3651). The rates of 3-year overall survival (OS), progression-free survival (PFS) and disease-free survival (DFS) were 80.30% (53/66), 69.70% (46/66) and 59.09% (39/66) in observational group, and 61.29% (19/31), 58.06% (18/31) and 58.06% (18/31) in control group, respectively. The OS in observational group was signiifcantly longer than in control group (P=0.035). However, there was no signiifcant difference in PFS, DFS and rate adverse reactions between 2 groups (P=0.089;P=0.438;χ2=0.1562,P=0.6927). Conclusion: Rituximab combined with chemotherapy can improve the efficacy of DLBCL without increasing the adverse reactions, which can be used as the ifrst-line treatment for DLBCL, thus deserving to be widely applied in clinic.

    2015-01-01

    Full Text Available Targeted therapy in retinoblastoma (RB is widely accepted as the current management tool with an aim of increasing drug availability at the tumor location. Inevitably the effect is several times higher compared to systemic delivery of chemotherapeutic drugs and carries less systemic toxicity. Despite tremendous advancement in saving life, eye salvage in advanced RB especially with active vitreous seeds remains a challenge. The hypoxic environment of the vitreous and reduced vitreous concentration of the drugs delivered makes these tumor seeds resistant to chemotherapy. Direct delivery of chemotherapeutic drugs into the vitreous cavity aids to overcome these challenges and is progressively being accepted worldwide. However, intraocular procedure in RB was abandoned due to high risk of extraocular tumor dissemination. Recently, the forbidden therapeutic technique was re-explored and modified for safe use. Although eye salvage rate has tremendously improved after intravitreal chemotherapy (IVitC, retinal toxicity, and vision salvage are yet to be validated. In our preliminary report of intravitreal melphalan in 11 eyes, we reported 100% eye salvage and 0% recurrence with an extended 15 months mean follow-up. In this review, we analyzed published reports on IVitC in RB via PubMed, Medline, and conference proceedings citation index, electronic database search, without language restriction that included case series and reports of humans and experimental animal eyes with RB receiving IVitC.

These viruses are known to have a devastating effect on crop production and constraint to the international exchange and conservation of banana germplasm-a cornerstone for breeding new cultivars. The viruses are particularly problematic in vegetative propagated crops, like bananas, because of their transmission in the planting material. Different virus eradication techniques have been developed, such as thermotherapy, chemotherapy, and meristem culture for providing virus-free planting material. Meristem culture proved to be the most effective procedure to eradicate phloem-associated viruses. This method requires isolation of meristematic dome of plant under the aseptic conditions and culture in an appropriate nutrient medium to develop new virus-free plants. Thermotherapy is another widely used virus eradication technique, which is initially carried out on in vivo or in vitro plants and eventually combined with meristem culture technique. The plantlets are initially grown at 28°C day temperature and increase it by 2°C per day until reaches 40°C and the night temperature at 28°C; maintain plants at 40°C for 4 weeks; excise meristem and culture onto the regeneration medium. In chemotherapy technique, antiviral chemical compound Virazole(®) is applied on meristem culture. Combination of these techniques is also applied to improve the eradication rate.

  16. Drug cocktail optimization in chemotherapy of cancer.

    Saskia Preissner

    Full Text Available BACKGROUND: In general, drug metabolism has to be considered to avoid adverse effects and ineffective therapy. In particular, chemotherapeutic drug cocktails strain drug metabolizing enzymes especially the cytochrome P450 family (CYP. Furthermore, a number of important chemotherapeutic drugs such as cyclophosphamide, ifosfamide, tamoxifen or procarbazine are administered as prodrugs and have to be activated by CYP. Therefore, the genetic variability of these enzymes should be taken into account to design appropriate therapeutic regimens to avoid inadequate drug administration, toxicity and inefficiency. OBJECTIVE: The aim of this work was to find drug interactions and to avoid side effects or ineffective therapy in chemotherapy. DATA SOURCES AND METHODS: Information on drug administration in the therapy of leukemia and their drug metabolism was collected from scientific literature and various web resources. We carried out an automated textmining approach. Abstracts of PubMed were filtered for relevant articles using specific keywords. Abstracts were automatically screened for antineoplastic drugs and their synonyms in combination with a set of human CYPs in title or abstract. RESULTS: We present a comprehensive analysis of over 100 common cancer treatment regimens regarding drug-drug interactions and present alternatives avoiding CYP overload. Typical concomitant medication, e.g. antiemetics or antibiotics is a preferred subject to improvement. A webtool, which allows drug cocktail optimization was developed and is publicly available on http://bioinformatics.charite.de/chemotherapy.

    Objective To investigate the inhibitory effects of combination chemotherapy of Carboplatin(CBP) ,Teniposide (Vm-26) ,Methasquin(MTX),and Nimodipine(NIM) on glioma,and to explore the sensitivity of glioma cells to different treatment regimens so as to provide some clues for clinical usage of interstitial combination chemotherapy. Methods MTT assay and 3H-TdR incorporation assay were performed to evaluate the inhibitory effects upon the proliferation of glioma cells,and to compare the sensitivity of glioma cells to administration of CBP,Vm-26, MTX, and NIM with that of the administration of CBP + NIM, Vm-26 + NIM, MTX + NIM, CBP + Vm-26 + MTX, or CBP + Vm-26 + MTX + NIM respectively. Results The inhibition rate of CBP + Vm-26 + MTX + NIM combination administration against glioma cells was 96.64%,which was higher than that of CBP + NIM (69.03%), Vm-26 + NIM (71.53%), MTX + NIM (52. 75% ), CBP + Vm-26 + MTX(78.59%)(P<0.01),and the dosage of CBP,Vm-26,and MTX was declined to 1/10 ~ 1/100 that of respective use of CBP,Vm-26,and MTX. Conclusions The curative effects of combination administration of CBP,Vm-26, MTX, and NIM was much better than that of respective administration,suggesting a higher inhibition rate and a lower dosage use.

    Recent studies indicate that cancer stem cells (CSCs) exist in most hematological and solid tumors. CSCs are characterized by their ability to self-renew and their capacity to differentiate into the multitude of cells that comprise the tumor mass. Moreover, these cells have been shown to be intrinsically resistant to conventional anticancer therapies. Despite their fundamental role in cancer pathogenesis, the cellular origin of CSCs remains highly controversial. The aim of this study was to examine whether heterogeneous cancer cells can acquire stem cell-like properties in response to chemotherapy. We demonstrate that carboplatin can induce the self-renewal (spherogenesis) and pluripotency (Sox2 and Oct3/4 expression) of hepatocellular carcinoma (HCC) cells grown under stem cell culture conditions. Moreover, we show that non-CSC cells, obtained by side population flow cytometric sorting using Hoechst 33342, can acquire stem-like properties after exposure to carboplatin. Finally, we show that knockdown of Sox2 and Oct3/4 gene expression in HCC cells can reduce carboplatin-mediated increases in sphere formation and increase cellular sensitivity to chemotherapy. Taken together, our data indicate that bulk cancer cells may be an important source of CSCs during tumor development, and that targeting Sox2 and/or Oct3/4 may be a promising approach for targeting CSCs in clinical cancer treatment.

  19. Cancer chemotherapy and cardiac arrhythmias: a review.

    Tamargo, Juan; Caballero, Ricardo; Delpón, Eva

    2015-02-01

    Cardiovascular toxicity is a potential complication of cancer chemotherapy (CC) that increases the morbidity and mortality of cancer patients. Cardiac arrhythmias have been reported as an adverse effect of many chemotherapeutic drugs, including novel targeted therapies. The relationship between chemotherapy and arrhythmias has not been well-established and the proarrhythmogenic mechanisms remain uncertain as they can be the result of a direct electrophysiological effect or of changes in cardiac structure and function, including myocardial ischaemia and heart failure, which create an arrhythmogenic substrate. In this review we summarise available evidence of proarrhythmia induced by CC, discuss the possible mechanisms involved in this adverse effect and emphasise the importance of cardiac monitoring for the early diagnosis, intervention and surveillance of those patients more susceptible to develop proarrhythmia in an attempt to reduce the morbidity and mortality. Oncologists should be fully aware of proarrhythmia and the close collaboration between cardiologists and oncologists would result in a better cardiovascular assessment, risk stratification, cardiac monitoring and treatment during CC and during the follow-up. The final objective is to understand the mechanisms of proarrhythmia and evaluate its real incidence and clinical relevance so as to select the safest and most effective treatment for cancer patients.

    Objective To investigate apoptosis in vivo in patients with leukemia at different stages of the first cycle of chemotherapy.Methods We detected apoptosis of HL-60 cells and peripheral blood leukemia cells in 17 patients at different stages, using in situ terminal deoxynucleotidyl transferase (TdT) fluorescence measurement and DNA electrophoresis. Results When HL-60 cells were incubated with 0.02 mg/L harringtonine for 0 to 48 hours, agarose gel electrophoresis showed that DNA ladder patterns became evident only at 12 hour into the treatment. In situ TdT assay showed that apoptotic cells occurred after one hour of the treatment. Apoptotic cells were few (0-3.3%) before chemotherapy, but increased substantially (11.4%-87.5%) during chemotherapy in patients with complete remission (CR) or partial remission (PR). Apoptotic cells were few (0-6.1%) during chemotherapy in ten patients with no remission (NR). DNA ladder cannot be detected by agarose gel electrophoresis either before, during or after chemotherapy. Wilcoxon signed rank test shows: P=0.0012<0.01, apoptotic cells during chemotherapy were present in greater quantity than prior to chemotherapy. Wilcoxon rank sum test shows: P=0.0011<0.01, with the median of apoptotic cells during chemotherapy in patients with CR or PR more than with NR.Conclusions TdT assay can be used to detect apoptotic cells earlier and more sensitively than DNA agarose gel electrophoresis. In situ TdT assay is useful to detect apoptosis in vivo in the initial phase of chemotherapy for immediate modification of the chemotherapy regimen, whereas electrophoretic analysis is not sensitive enough to detect apoptotic cell in vivo. Where the median of apoptotic cells during chemotherapy in patients with CR or PR were greater than with NR, only effective drug therapy could induce apoptosis.

  1. WE-D-BRE-04: Modeling Optimal Concurrent Chemotherapy Schedules

    Energy Technology Data Exchange (ETDEWEB)

    Jeong, J; Deasy, J O [Memorial Sloan Kettering Cancer Center, New York, NY (United States)

    2014-06-15

    Purpose: Concurrent chemo-radiation therapy (CCRT) has become a more common cancer treatment option with a better tumor control rate for several tumor sites, including head and neck and lung cancer. In this work, possible optimal chemotherapy schedules were investigated by implementing chemotherapy cell-kill into a tumor response model of RT. Methods: The chemotherapy effect has been added into a published model (Jeong et al., PMB (2013) 58:4897), in which the tumor response to RT can be simulated with the effects of hypoxia and proliferation. Based on the two-compartment pharmacokinetic model, the temporal concentration of chemotherapy agent was estimated. Log cell-kill was assumed and the cell-kill constant was estimated from the observed increase in local control due to concurrent chemotherapy. For a simplified two cycle CCRT regime, several different starting times and intervals were simulated with conventional RT regime (2Gy/fx, 5fx/wk). The effectiveness of CCRT was evaluated in terms of reduction in radiation dose required for 50% of control to find the optimal chemotherapy schedule. Results: Assuming the typical slope of dose response curve (γ50=2), the observed 10% increase in local control rate was evaluated to be equivalent to an extra RT dose of about 4 Gy, from which the cell-kill rate of chemotherapy was derived to be about 0.35. Best response was obtained when chemotherapy was started at about 3 weeks after RT began. As the interval between two cycles decreases, the efficacy of chemotherapy increases with broader range of optimal starting times. Conclusion: The effect of chemotherapy has been implemented into the resource-conservation tumor response model to investigate CCRT. The results suggest that the concurrent chemotherapy might be more effective when delayed for about 3 weeks, due to lower tumor burden and a larger fraction of proliferating cells after reoxygenation.

    Gestational trophoblastic neoplasia (GTN) is a highly curable group of pregnancy-related tumours; however, approximately 25% of GTN tumours will be resistant to, or will relapse after, initial chemotherapy. These resistant and relapsed lesions will require salvage chemotherapy with or without surgery. Various salvage regimens are used worldwide. It is unclear which regimens are the most effective and the least toxic.

  5. Chemotherapy-induced alopecia: advice and support for hair loss.

    Science.gov (United States)

    Roe, Helen

    This article provides insight into the growth cycle of a hair follicle and the potential impact chemotherapy agents can have on this process, which often results in hair loss (alopecia). It explores the psychological consequences of chemotherapy-induced alopecia for an individual as a result of the perceptions of others as well as an individual's perception of his or her self-image. Despite the development of various forms of scalp cooling, chemotherapy-induced alopecia remains a major side effect for patients receiving chemotherapy; however, there have been improvements in wig provision and changing public opinion relating to baldness. Although chemotherapy-induced alopecia affects both males and females and all age groups, this article focuses on the potential impact for patients receiving chemotherapy as a form of treatment for breast cancer. As professionals we need to understand the social significance of hair in relation to a person's outward presentation and social interactions, along with the possible psychological implications of a person losing his or her bodily hair, and not just the head hair. We must aim to minimize the distress alopecia can cause by: ensuring we provide patients with up-to-date verbal and written information to enable them to prepare for losing their hair; helping them to preserve their self-image and minimize the psychological consequences of hair loss while receiving chemotherapy; and preparing them for their hair re-growth following completion of chemotherapy.

    Appetite loss during cancer chemotherapy may lead to malnutrition and a decreased quality of life. To overcome this problem, evidence-based guidelines have been established for chemotherapy-induced emesis and mucositis. However, unsolved issues such as taste alimentation remain. Since the clinical picture of appetite loss is complex, individual management strategies depending on the type of the disease and treatment are required.

    2013-01-01

    Full Text Available Cytotoxic chemotherapy prolongs survival of patients with advanced and metastatic tumors. This is, however, a double-edged sword with many adverse effects. Since the liver has a rich blood supply and plays an active role in the metabolism of medications, it is not surprising that there can be hepatic injury related to chemotherapy. In addition, radioembolization may affect the parenchyma of normal and cirrhotic livers. We review chemotherapy-associated liver injury in patients with colorectal liver metastases, including downsizing chemotherapy and neoadjuvant chemotherapy. We discuss the mechanism of the hepatic injury, secondary to reactive oxygen species, and the spectrum of hepatic injury including, steatosis, steatohepatitis, hepatic sinusoidal injury and highlight the pharmacogenomics of such liver insults. Methods for reducing and treating the hepatotoxicity are discussed for specific agents including tamxifen and the newly introduced targeted antibodies.

    Antineoplastic chemotherapy (CT) represents the systemic treatment of malignant tumors. It can be used alone or combined with surgery and / or radiotherapy. The cytotoxic agents used in chemotherapy work on both cancerous cells and noncancerous cells of the body, generally resulting in high toxicity. The biological aggressiveness of chemotherapy particularly affects rapidly replicating cells, such as those of the digestive tract, resulting in adverse effects that impair food intake, leading to compromised nutritional status and which may lead to cachexia. The main toxic effects of chemotherapy in the gastrointestinal tract include nausea, vomiting -these are the most frequent- constipation, diarrhea, xerostomia, mucositis, dysphagia and anorexia. Given the high frequency of such effects, nutritional intervention should be an integral part of cancer treatment, to maintain and/or improve the patient's nutritional status and reduce or minimize the side effects caused by treatment. Accordingly, the goal of this study is to review dietetic conduct in the process of caring for patients undergoing cancer chemotherapy.

    This narrative review focuses on the role of sarcopenia and chemotherapy-induced toxicity in cancer patients. Consistent evidence shows that sarcopenia in cancer patients leads to decreased overall survival by influencing treatment discontinuation and dose reduction. Therefore, sarcopenia should be considered a robust prognostic factor of negative outcome as well as a determinant of increased healthcare costs. RESUMO Esta revisão narrativa descreve o papel da sarcopenia e a toxicidade mediada pela quimioterapia em pacientes com câncer. Diversas evidências consistentes mostram que a sarcopenia em pacientes com câncer induz à menor sobrevida global, por influenciar na interrupção do tratamento e na redução da dose. Portanto, a sarcopenia pode ser considerada um importante fator de prognóstico de desfecho negativo, além de um determinante de maiores custos em saúde.

    Trump, Donald; Lau, Yiu-Keung

    2003-06-01

    The role of chemotherapy in prostate cancer continues to evolve. In men with symptomatic androgen-independent prostate cancer, significant reduction in pain and analgesic requirements are achievable with mitoxantrone and glucocorticoid combinations compared with glucocorticoids alone. However, survival rates are not improved. Taxane-based combinations with estramustine phosphate or other new agents show promise. Prostate-specific antigen response rates with these combinations appear to be 1.5 to 2 times more frequent than with mitoxantrone-based combinations. Randomized trials of taxane versus mitoxantrone-based therapies are underway. New agents and applications of current agents in adjuvant settings should be explored if survival in men with prostate cancer is to be improved.

    As a specific variation of chemotherapy-induced nausea and vomiting, anticipatory nausea and vomiting (ANV) appears particularly linked to psychological processes. The three predominant factors related to ANV are classical conditioning; demographic and treatment-related factors; and anxiety or negative expectancies. Laboratory models have provided some support for these underlying mechanisms for ANV. ANV may be treated with medical or pharmacological interventions, including benzodiazepines and other psychotropic medications. However, behavioral treatments, including systematic desensitization, remain first line options for addressing ANV. Some complementary treatment approaches have shown promise in reducing ANV symptoms. Additional research into these approaches is needed. This review will address the underlying models of ANV and provide a discussion of these various treatment options.

    2009-07-01

    A mathematical model is used to investigate the effectiveness of the chemotherapy drug Topotecan against neuroblastoma. Optimal control theory is applied to minimize the tumor volume and the amount of drug utilized. The model incorporates a state constraint that requires the level of circulating neutrophils (white blood cells that form an integral part of the immune system) to remain above an acceptable value. The treatment schedule is designed to simultaneously satisfy this constraint and achieve the best results in fighting the tumor. Existence and uniqueness of the solution of the optimality system, which is the state system coupled with the adjoint system, is established. Numerical simulations are given to demonstrate the behavior of the tumor and the immune system components represented in the model.

    2012-07-01

    Efflux pump mechanisms perform important physiological functions such as prevention of toxin absorption from the gastrointestinal tract, elimination of bile from the hepatocytes, effective functioning of the blood-brain barrier and placental barrier, and renal excretion of drugs. They exist in all living cells, but those in the bacterial and mammalian cells are more important to the clinician and pharmacologist, as they constitute an important cause of antimicrobial drug resistance, which contributes to treatment failure, high medical bills, and increased mortality / morbidity. This review was aimed at highlighting the role of efflux pump mechanisms in microbial resistance to chemotherapeutic agents. It was also aimed to elucidate their structure and mechanisms of action so as to integrate the efflux pump mechanisms in the design and development of novel antimicrobial agents. Findings from previous studies and research on this subject assessed through Google search, Pubmed, Hinari websites, as well as standard textbooks on chemotherapy, provided the needed information in the process of this review. Efflux pump inhibitors are promising strategies for preventing and reverting efflux-mediated resistance to chemotherapeutic agents. They are usually employed as adjuncts in antimicrobial and cancer chemotherapy. Toxicity, more common with the older-generation inhibitors such as verapamil and reserpine, constitutes the greatest impediment to their clinical applications. No efflux pump inhibitor has been approved for routine clinical use, as a result of doubtful clinical efficacy and unacceptably high incidence of adverse effects, particularly inhibition of the P-450 drug metabolizing enzyme. At present, their applications are mainly restricted to epidemiological studies. Nonetheless, the search for efficacious and tolerable efflux pump inhibitors continues because of the potential benefits. There is a need to consider efflux pump substrate selectivity in the design and

    Full Text Available Background: Today’s healthcare organizations are challenged by pressures to meet growing population demands and enhance community health through improving service quality. Quality function deployment is one of the widely-used customerdriven approaches for health services development. In the current study, quality function deployment is used to improve the quality of chemotherapy unit services. Methods: First, we identified chemotherapy outpatient unit patients as chemotherapy unit customers. Then, the Delphi technique and component factor analysis with orthogonal rotation was employed to determine their expectations. Thereafter, data envelopment analysis was performed to specify user priorities. We determined the relationships between patients’ expectations and service elements through expert group consensus using the Delphi method and the relationships between service elements by Pearson correlation. Finally, simple and compound priorities of the service elements were derived by matrix calculation. Results: Chemotherapy unit patients had four main expectations: access, suitable hotel services, satisfactory and effective relationships, and clinical services. The chemotherapy unit has six key service elements of equipment, materials, human resources, physical space, basic facilities, and communication and training. There were four-level relationships between the patients’ expectations and service elements, with mostly significant correlations between service elements. According to the findings, the functional group of basic facilities was the most critical factor, followed by materials. Conclusion: The findings of the current study can be a general guideline as well as a scientific, structured framework for chemotherapy unit decision makers in order to improve chemotherapy unit services.

    The objective of the study was to evaluate the effect of neoadjuvant chemotherapy on the survival of patients with oropharyngeal cancer. Patients with a squamous cell carcinoma of the oropharynx for whom curative radiotherapy or surgery was considered feasible were entered in a multicentric randomized trial comparing neoadjuvant chemotherapy followed by loco-regional treatment to the same loco-regional treatment without chemotherapy. The loco-regional treatment consisted either of surgery plus radiotherapy or of radiotherapy alone. Three cycles of chemotherapy consisting of Cisplatin (100 mg/m2) on day 1 followed by a 24-hour i.v. infusion of fluorouracil (1000 mg/m2/day) for 5 days were delivered every 21 days. 2–3 weeks after the end of chemotherapy, local treatment was performed. The trial was conducted by the Groupe d'Etude des Tumeurs de la Tête Et du Cou (GETTEC). A total of 318 patients were enrolled in the study between 1986 and 1992. Overall survival was significantly better (P = 0.03) in the neoadjuvant chemotherapy group than in the control group, with a median survival of 5.1 years versus 3.3 years in the no chemotherapy group. The effect of neoadjuvant chemotherapy on event-free survival was smaller and of borderline significance (P = 0.11). Stratification of the results on the type of local treatment, surgery plus radiotherapy or radiotherapy alone, did not reveal any heterogeneity in the effect of chemotherapy. © 2000 Cancer Research Campaign http://www.bjcancer.com PMID:11189100

    Full Text Available The tools for managing retinoblastoma have been increasing in the past decade. While globe-salvage still relies heavily on intravenous chemotherapy, tumors in advanced stage that failed chemotherapy are now referred for intra-arterial chemotherapy (IAC to avoid enucleation. However, IAC still has many obstacles to overcome. We present an update on the indications, complications, limitations, success, and technical aspects of IAC. Given its safety and high efficacy, it is expected that IAC will replace conventional strategies and will become a first-line option even for tumors that are amenable for other strategies.

    Full Text Available Abstract Background Patients with cancer must make frequent visits to the clinic not only for chemotherapy but also for the management of treatment-related adverse effects. Neutropenia, the most common dose-limiting toxicity of myelosuppressive chemotherapy, has substantial clinical and economic consequences. Colony-stimulating factors such as filgrastim and pegfilgrastim can reduce the incidence of neutropenia, but the clinic visits for these treatments can disrupt patients' routines and activities. Methods We surveyed patients to assess how clinic visits for treatment with chemotherapy and the management of neutropenia affect their time and activities. Results The mean amounts of time affected by these visits ranged from approximately 109 hours (hospitalization for neutropenia and 8 hours (physician and chemotherapy to less than 3 hours (laboratory and treatment with filgrastim or pegfilgrastim. The visits for filgrastim or pegfilgrastim were comparable in length, but treatment with filgrastim requires several visits per chemotherapy cycle and treatment with pegfilgrastim requires only 1 visit. Conclusions This study provides useful information for future modelling of additional factors such as disease status and chemotherapy schedule and provides information that should be considered in managing chemotherapy-induced neutropenia.

    2000-01-01

    Objective: To study the use of interventional chemotherapy in comprehensive treatment for advanced nasopharyngeal carcinoma. Methods: Interventional chemotherapy with multi-drugs including cisplatin (DDP) 100 mg, 5-fluorouracil (5-FU) 1000 mg and bleomycin (BLM) 16 mg was used to treat 30 cases with advanced nasopharyngeal carcinoma before radiotherapy. 50 cases that received radiotherapy alone were used as a control group. The methods, time and dose schedule of radiotherapy were similar in the two groups. Results: The primary lesions in 16 cases and the cervical lymph nodes in 12 cases were reduced in size after interventional chemotherapy. Radiation doses of those in complete response in their primary lesion and cervical lymph nodes were lower than that of the control group (P<0.05). The complete response rate of study group was 83.3% and that of control group was 72.0% (P<0.05). Conclusion: Interventional chemotherapy plus radiotherapy is a valuable treatment method in advanced nasopharyngeal carcinoma.

    Full Text Available In patients with pseudomyxoma peritonei or peritoneal mesothelioma, direct extension of disease through the hemidiaphragm may result in an isolated progression of tumor within the pleural space. We monitored the intrapleural and plasma levels of mitomycin C and doxorubicin by HPLC assay in order to determine the pharmacokinetic behavior of this intracavitary use of chemotherapy. Our results showed a persistent high concentration of intrapleural drug as compared to plasma concentrations. The increased exposure for mitomycin C was 96, and the increased exposure for doxorubicin was 241. When the clearance of chemotherapy from the thoracic cavity was compared to clearance from the abdomen and pelvis, there was a considerably more rapid clearance from the abdomen as compared to the thorax. The pharmacologic study of intrapleural chemotherapy in these patients provides a strong pharmacologic rationale for regional chemotherapy in this group of patients.

    Dose intensification of chemotherapy is thought to increase survival. With recent advances in hemopoietic cell modulators such as granulocyte colony stimulating factor, the limiting toxicity of intensifying chemotherapeutic regimens has become the severity of the associated enterocolitis. In animal models, glutamine protects the host from methotrexate-induced enterocolitis. This study evaluates the effects of a glutamine-supplemented diet on the tumoricidal effectiveness of methotrexate. Sarcoma-bearing Fisher 344 rats (n = 30) were pair-fed an isocaloric elemental diet containing 1% glutamine or an isonitrogenous amount of glycine beginning on day 25 of the study. Rats from each group received two intraperitoneal injections of methotrexate (5 mg/kg) or saline on days 26 and 33 of the study. On day 40, rats were killed, tumor volume and weight were recorded, and tumor glutaminase activity and tumor morphometrics were measured. Blood was taken for arterial glutamine content, complete blood count, and blood culture. The gut was processed for glutaminase activity and synthesis phase of the deoxyribonucleic acid. In rats receiving methotrexate, the tumor volume loss was nearly doubled when glutamine was added to the diet. Significant differences in tumor glutaminase activity and morphometrics were not detected. The toxicity to the host was ameliorated. Significantly increased synthesis phase of deoxyribonucleic acid of the whole jejunum, decreased bacteremia, "sepsis," and mortality were demonstrated. Glutamine supplementation enhances the tumoricidal effectiveness of methotrexate while reducing its morbidity and mortality in this sarcoma rat model.

    Chemotherapy is one of the prevailing methods used to treat malignant tumours, but the outcome and prognosis of tumour patients are not optimistic. Cancer cells gradually generate resistance to almost all chemotherapeutic drugs via a variety of distinct mechanisms and pathways. Chemotherapeutic resistance, either intrinsic or acquired, is caused and sustained by reduced drug accumulation and increased drug export, alterations in drug targets and signalling transduction molecules, increased repair of drug-induced DNA damage, and evasion of apoptosis. In order to better understand the mechanisms of chemoresistance, this review highlights our current knowledge of the role of altered drug metabolism and transport and deregulation of apoptosis and autophagy in the development of tumour chemoresistance. Reduced intracellular activation of prodrugs (e.g. thiotepa and tegafur) or enhanced drug inactivation by Phase I and II enzymes contributes to the development of chemoresistance. Both primary and acquired resistance can be caused by alterations in the transport of anticancer drugs which is mediated by a variety of drug transporters such as P-glycoprotein (P-gp), multidrug resistance associated proteins, and breast cancer resistance protein. Presently there is a line of evidence indicating that deregulation of programmed cell death including apoptosis and autophagy is also an important mechanism for tumour resistance to anticancer drugs. Reversal of chemoresistance is likely via pharmacological and biological approaches. Further studies are warranted to grasp the full picture of how each type of cancer cells develop resistance to anticancer drugs and to identify novel strategies to overcome it.

    Over 15 years ago, low-dose metronomic chemotherapy was shown to induce disease control in patients with advanced-stage breast cancer with a lower incidence of adverse events compared with conventional maximum tolerated dose chemotherapy. Good response rates have been seen in heavily pre-treated patients for whom limited treatment options are available. Most patients prefer oral therapy and metronomic chemotherapy is a convenient alternative in patients with advanced-stage disease in which minimal toxicity and good tumour control are the overall aims of treatment. The addition of metronomic protocols to standard neoadjuvant chemotherapy regimens has produced promising pathological complete response rates. Ongoing trials including the SYSUCC-001 trial in patients with triple-negative breast cancer and the IBCSG 22-00 trial that is assessing a cyclophosphamide-methotrexate maintenance regimen after standard adjuvant therapy in hormone receptor-negative disease, will clarify the value of adding this approach to conventional therapies. The low cost associated with metronomic chemotherapy represents an opportunity for the utilization of this treatment option, especially in developing countries, and poses a challenge for the launch of large trials sponsored by industry. Using breast cancer as the principal example, we discuss the key clinical advances in this area, including new trial design, appropriate patient and end point selection, as well as the evolving rationale for metronomic chemotherapy combinations.

    Although side effects of cancer chemotherapy are well known, "opposite effects" of chemotherapy which enhance the malignancy of the treated cancer are not well understood. We have observed a number of steps of malignancy that are enhanced by chemotherapy pre-treatment of mice before transplantation of human tumor cells. The induction of intravascular proliferation, extravasation, and colony formation by cancer cells, critical steps of metastasis was enhanced by pretreatment of host mice with the commonly-used chemotherapy drug cyclophosphamide. Cyclophosphamide appears to interfere with a host process that inhibits intravascular proliferation, extravasation, and extravascular colony formation by at least some tumor cells. Cyclophosphamide does not directly affect the cancer cells since cyclophosphamide has been cleared by the time the cancer cells were injected. Without cyclophosphamide pretreatment, human colon cancer cells died quickly after injection in the portal vein of nude mice. Extensive clasmocytosis (destruction of the cytoplasm) of the cancer cells occurred within 6 hours. The number of apoptotic cells rapidly increased within the portal vein within 12 hours of injection. However, when the host mice were pretreated with cyclophosphamide, the cancer cells survived and formed colonies in the liver after portal vein injection. These results suggest that a cyclophosphamide-sensitive host cellular system attacked the cancer cells. This review describes an important unexpected "opposite effects" of chemotherapy that enhances critical steps in malignancy rather than inhibiting them, suggesting that certain current approaches to cancer chemotherapy should be modified.

    Management of febrile neutropenia (FN) is important for the safety of patients undergoing outpatient chemotherapy. Oral antimicrobials are usually prescribed as the initial treatment for FN, and outpatients are instructed to begin medication prior to chemotherapy. However, the effectiveness and safety of the use of these oral antibiotics have not yet been established. In this study, we investigated the effectiveness and safety of levofloxacin hydrate (LVFX) for breast cancer patients with FN, and the factors associated with the onset of FN in 134 breast cancer patients who underwent chemotherapy including the anticancer drug anthracycline (total, 513 courses), in an outpatient chemotherapy department. The effectiveness and safety of LVFX were defined respectively as defervescence within 5 days, and the appearance of side effects such as diarrhea and rashes. Fever was observed in 89 (66%) of the 134 patients, and during 164 (32%) of 513 courses. Defervescence was observed with the LVFX medication in 149 (93%) of 160 courses. The primary side effect was the development of rashes, and only 2 (1%) of the 160 courses were discontinued. Onset of stomatitis during chemotherapy was observed as a factor of FN (odds ratio: 1.36, p<0.05). Our results suggest that the use of LVFX according to the patients' discretion might be an effective and safe option for the management of FN during outpatient chemotherapy.

    Background:As a surrogate marker of systemic inlfammation, the lymphocyte‑to‑monocyte ratio (LMR) is an independent prognostic factor for various malignancies. This study investigated the prognostic signiifcance of the pre‑chemotherapy LMR in patients with previously untreated metastatic colorectal cancer (mCRC) receiving chemotherapy. Methods:The present study included newly diagnosed mCRC patients treated between January 2005 and Decem‑ber 2013 with FOLFOX chemotherapy, speciifcally oxaliplatin 180mg/m2 on day 1, with leucovorin 400mg/m2 administered as a 2‑hour infusion before the administration of 5‑lfuorouracil 400mg/m2 as an intravenous bolus injection, and 5‑lfuorouracil 2400mg/m2 as a 46‑h infusion immediately after 5‑lfuorouracil bolus injection. The LMR was calculated as the absolute count of lymphocytes divided by the absolute count of monocytes. COX proportional hazards analysis was performed to evaluate the association of LMR with survival outcomes. Results:A total of 488 patients were included. Patients with high pre‑chemotherapy LMR experienced signiif‑cant improvements in progression‑free survival (PFS, 9.2 vs. 7.6months,P<0.001) and overall survival (OS, 19.4 vs. 16.6months,P<0.001) compared with patients with low pre‑chemotherapy LMR. Subsequent COX multivariate analysis showed that high pre‑chemotherapy LMR (≥3.11) was an independent favorable prognostic factor for PFS and OS. Additionally, patients whose LMR remained high (high–high subgroup), increased (low–high subgroup), or decreased (high–low subgroup) following chemotherapy showed better results in terms of PFS and OS than patients whose LMR remained low (low–low subgroup) after chemotherapy. Conclusions:For patients with previously untreated mCRC receiving FOLFOX chemotherapy, an elevated pre‑chem‑otherapy LMR is an independent favorable prognostic factor for PFS and OS, and changes in the LMR before and after chemotherapy seem to predict the

    Purpose Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) have been proposed for controlling peritoneal seeding metastasis in some kinds of cancers, including those of colorectal origin, but their safety and oncological benefits are subjects of debate. We present our early experience with those procedures. Methods Data were retrospectively collected from all patients with peritoneal carcinomatosis (PC) and pseudomyxoma peritonei (PMP) treated using CRS and HIPEC at Yonsei Cancer Center between July 2014 and July 2015. Short-term outcomes and risk factors for postoperative complications were analyzed. Results Twenty-three patients with PC (n = 18) and PMP (n = 5) underwent CRS and HIPEC. Median follow-up and age were 2 months and 54 years, respectively. The median peritoneal carcinomatosis index score was 15, and CC0-1 was achieved in 78.3% of all patients. The median operation time and bleeding loss were 590 minutes and 570 mL, respectively. Grade-IIIa/grade-IIIb complications occurred in 4.3% (n = 1)/26.1% (n = 6) of the patients within 30 days postoperatively, and no 30-day mortalities were reported. Factors related to postoperative complications with CRS and HIPEC were number of organ resection (P = 0.013), longer operation time (P patients treated with cetuximab for recurred colorectal cancer had grade-III postoperative complication. Conclusion Our initial experience with CRS and HIPEC presented about 30% grade-III postoperative complications. Therefore, expert surgeons need to perform those procedures with great caution in selected patients who might benefit from it.

    In the present investigation, curcumin loaded magnetically active frustules have been reported. The diatoms were cultured and frustules were obtained by chemical and thermal processes. The frustules were rendered magnetically active by incorporation of iron oxide nanoparticle using two different methods involving ferrofluid (CMDM-F) and in situ synthesis (CMDM-I) of iron oxide nanoparticle. These CMDM prepared by two techniques were characterized using FT-IR and vibrating sample magnetometer (VSM) analyses. Particle size and potential were measured using the Malvern Zetasizer. Scanning electron microscopy (SEM) was utilized for studying the surface morphology of CMDM, and in addition to this elemental analysis was also performed for confirming the presence of iron. The cell viability assay was carried out using the HeLa cell line. SEM images showed a change in surface morphology of diatoms before and after rendering magnetic activity. Cell viability assay revealed that CMDM-F had reasonably high cytotoxicity (60.2%) compared to Curcumin (42.1%), DM (1.9%), CDM (44.8%), and CMDM-I (59.9). Both, CMDM-F and CMDM-I showed improved cytotoxicity when compared with pure curcumin. The overall study suggests that the developed CMDM could be utilized as a potential carrier to deliver cargo for efficient chemotherapy. - Highlights: • In-lab culture and purification of Diatoms with pore size around 50 nm • A simple one step synthesis of magnetically active Diatoms using ferrofluid which has not been reported till date • Comparative study of magnetically active Diatoms synthesized using ferrofluid method and in situ method • Cell viability study of curcumin loaded magnetically active diatoms.

    Background Steroid-induced sleep disturbance is a common and highly distressing morbidity for children receiving steroid chemotherapy for the treatment of pediatric acute lymphoblastic leukemia (ALL). Sleep disturbance can negatively impact overall quality of life, neurodevelopment, memory consolidation, and wound healing. Hypothalamic orexin neurons are influential wake-promoting neurons, and disturbances in orexin signaling leads to abnormal sleep behavior. A new class of drug, the orexin receptor antagonists, could be an intriguing option for sleep disorders caused by increased orexinergic output. Our aim was to examine the impact of ALL treatment doses of corticosteroids on the orexin system in rodents and in children undergoing treatment for childhood ALL. Methods We administered repeated injections of dexamethasone to rodents and measured responsive orexin neural activity compared to controls. In children with newly diagnosed standard risk B-cell ALL receiving dexamethasone therapy per Children’s Oncology Group (COG) induction therapy from 2014–2016, we collected pre- and during-steroids matched CSF samples and measured the impact of steroids on CSF orexin concentration. Results In both rodents, all markers orexin signaling, including orexin neural output and orexin receptor expression, were preserved in the setting of dexamethasone. Additionally, we did not detect a difference in pre- and during-dexamethasone CSF orexin concentrations in children receiving dexamethasone. Conclusions Our results demonstrate that rodent and human orexin physiology is largely preserved in the setting of high dose dexamethasone. The data obtained in our experimental model fail to demonstrate a causative role for disruption of the orexin pathway in steroid-induced sleep disturbance. PMID:27997622

    Full Text Available Context Seventy patients with adenocarcinoma of the pancreas with liver metastases, received chemotherapy every four weeks and their outcomes are reported in this retrospective series. Objective Advanced adenocarcinoma of the pancreas has a poor prognosis with only 2% 5-year survival reported by SEER (Surveillance, Epidemiology and End Results of the NCI. Chemotherapy given as intra-arterial perfusions is more intense than intravenous chemotherapy. Responses in perfused tumor is expected to be better than that obtained with only intravenous chemotherapy. Design Hepatic artery therapy is given monthly as a 5 hour perfusion of the hepatic artery using DDP and MIC. Also given is monthy Intravenous (IV therapy with four hours of Leucovorin (LV, with an injection of FUDR during the last hour of LV, daily x 5 days. Setting all therapy was given at Midwestern Regional Medical Center. Patients Thirty seven patients had no prior chemotherapy, while 33 patients had progressed after prior IV chemotherapy. Intervention Hepatic artery therapy with IV LV-FUDR was given for up to six months depending upon marrow tolerance and response. At that point, if response was ongoing or improving, therapy was continued monthly with only IV LV-FUDR; all therapy was stopped whenever progressive disease was evident. Results of those without prior chemotherapy, the mean overall survival (OS was 17.3 ± 30.2 months (mean±SD, ranging up to 13 years. Six patients survived more than three years with four are living in continuing complete remission for more than five years. Conclusion This therapy offers the opportunity for long term survival in a subset of patients with metastatic adenocarcinoma of the pancreas who have liver metastases, and some patients can be cured.

    Background: Vomiting is one of the most prevalent side effects of chemotherapy in cancer patients. The aim of this study was to evaluate the effect of ginger plant on chemotherapy-induced vomiting, since the previous studies were somehow imperfect and have provided controversial results. Materials and Methods: This randomized double-blind placebo-controlled clinical trial was conducted on 80 women with breast cancer undergoing chemotherapy and suffering from vomiting in Imam Khomeini Hospital, Tehran, Iran, between July and December 2009. During a convenience sampling the participants were randomly allocated into treatment and placebo groups after taking a written informed consent. Two groups were matched based on the age and emetic risk of chemotherapy drugs. The treatment group received 250 mg ginger powder capsules (Zintoma) and placebo group 250 mg starch capsules 4 times a day (1 g/day) for 6 days since 3 days before chemotherapy session. A two-part self-made questionnaire was used to assess the effect of ginger. Patients completed the instrument every day. Then by STATA software version 8, the gathered data were analyzed using Fisher’s exact, Kruskal-Wallis, and Chi-square tests. Results: The 2 groups had no significant age differences and were matched (ginger: 41.8±8.4 vs placebo: 45.1±10, P = 0.1). Vomiting cases were significantly lower in ginger group at anticipatory (P = 0.04), acute (P = 0.04), and delayed (P = 0.003) phases. Also, heartburn was the only and venial reported side effect (P > 0.05). Conclusions: Taking ginger capsules (for 6 days since 3 days before chemotherapy) accompanied by the routine antiemetic treatment could relieve chemotherapy-induced vomiting in all phases.

  16. Metronomic Chemotherapy: Low Dose Less Toxicity Anticancer Strategy

    Directory of Open Access Journals (Sweden)

    Anjan Khadka

    2016-06-01

    Full Text Available Metronomic chemotherapy is the frequent administration of chemotherapy drugs at doses below the maximum tolerated dose and with no prolonged drug‑free break. It thus achieves a sustained low blood level of the drug without significant toxic side‑effects. Metronomic therapy leads to sustained plasma concentration of the drug without significant toxic side‑effects and hence there is reduced need for supportive therapy. However in case of conventional therapy toxicity is a concern. Metronomic chemotherapy exerts both direct and indirect effects on tumor cells and their microenvironment. It can inhibit tumor angiogenesis, stimulate anticancer immune response and also induces tumor dormancy. Optimizing a metronomic anticancer therapy is still a challenging task. New strategies are being developed to combine metronomic chemotherapy with conventional chemotherapy, radiotherapy and/or targeted therapy. An important disadvantage of this type of regimen is the empiricism in finding the optimal ‘low‑dose’ and in monitoring therapeutic efficacy during the course of treatment.

  17. Immune Modulation by Chemotherapy or Immunotherapy to Enhance Cancer Vaccines

    2011-08-01

    Full Text Available Chemotherapy has been a mainstay in cancer treatment for many years. Despite some success, the cure rate with chemotherapy remains unsatisfactory in some types of cancers, and severe side effects from these treatments are a concern. Recently, understanding of the dynamic interplay between the tumor and immune system has led to the development of novel immunotherapies, including cancer vaccines. Cancer vaccines have many advantageous features, but their use has been hampered by poor immunogenicity. Many developments have increased their potency in pre-clinical models, but cancer vaccines continue to have a poor clinical track record. In part, this could be due to an inability to effectively overcome tumor-induced immune suppression. It had been generally assumed that immune-stimulatory cancer vaccines could not be used in combination with immunosuppressive chemotherapies, but recent evidence has challenged this dogma. Chemotherapies could be used to condition the immune system and tumor to create an environment where cancer vaccines have a better chance of success. Other types of immunotherapies could also be used to modulate the immune system. This review will discuss how immune modulation by chemotherapy or immunotherapy could be used to bolster the effects of cancer vaccines and discuss the advantages and disadvantages of these treatments.

  18. Glutamine: A novel approach to chemotherapy-induced toxicity

    Directory of Open Access Journals (Sweden)

    2012-01-01

    Full Text Available Treatment of cancer is associated with short- and long-term side-effects. Cancer produces a state of glutamine deficiency, which is further aggravated by toxic effects of chemotherapeutic agents leading to increased tolerance of tumor to chemotherapy as well as reduced tolerance of normal tissues to the side-effects of chemotherapy. This article reviews the possible role of glutamine supplementation in reducing the serious adverse events in patients treated with anticancer drugs. The literature related to the possible role of glutamine in humans with cancer and the supportive evidence from animal studies was reviewed. Searches were made and the literature was retrieved using PUBMED, MEDLINE, COCHRANE LIBRARY, CENAHL and EMBASE, with a greater emphasis on the recent advances and clinical trials. Glutamine supplementation was found to protect against radiation-induced mucositis, anthracycline-induced cardiotoxicity and paclitaxel-related myalgias/arthralgias. Glutamine may prevent neurotoxicity of paclitaxel, cisplatin, oxaplatin bortezomib and lenolidamide, and is beneficial in the reduction of the dose-limiting gastrointestinal toxic effects of irinotecan and 5-FU-induced mucositis and stomatitis. Dietary glutamine reduces the severity of the immunosuppressive effect induced by methotrexate and improves the immune status of rats recovering from chemotherapy. In patients with acute myeloid leukemia requiring parenteral nutrition, glycyl-glutamine supplementation could hasten neutrophil recovery after intensive myelosuppressive chemotherapy. Current data supports the usefulness of glutamine supplementation in reducing complications of chemotherapy; however, paucity of clinical trials weakens the clear interpretation of these findings.

    2011-12-01

    Full Text Available Despite treatment with radical cystectomy and pelvic lymph node dissection, muscle invasive bladder cancer has a relapse rate of 50%. Patients can develop regionally advanced or metastatic disease that ultimately leads to death. The addition of neoadjuvant or adjuvant chemotherapy to reduce the risk of relapse and death has been extensively studied over the past two decades. Two contemporary trials coupled with a recent meta-analysis evaluating neoadjuvant chemotherapy demonstrated a modest but real improvement in overall survival. This has made neoadjuvant chemotherapy a standard of care. Clinical trials evaluating adjuvant chemotherapy in patients with high-risk disease have been plagued with statistical flaws and have, therefore, been unable to define the survival impact of this approach. It is hoped that ongoing adjuvant trials that are powered to detect small but meaningful clinical differences will clarify the benefit of chemotherapy after cystectomy. Since there are theoretical advantages and disadvantages to each of these approaches, both are widely used in North America. The evidence behind each approach and potential future developments in this field will be described.

    2015-01-01

    Breast cancer is the most common cause of cancer and cancer death worldwide. Although most patients present with localized breast cancer and may be rendered disease-free with local therapy, distant recurrence is common and is the primary cause of death from the disease. Adjuvant systemic therapies are effective in reducing the risk of distant and local recurrence, including endocrine therapy, anti-HER2 therapy, and chemotherapy, even in patients at low risk of recurrence. The widespread use of adjuvant systemic therapy has contributed to reduced breast cancer mortality rates. Adjuvant cytotoxic chemotherapy regimens have evolved from single alkylating agents to polychemotherapy regimens incorporating anthracyclines and/or taxanes. This review summarizes key milestones in the evolution of adjuvant systemic therapy in general, and adjuvant chemotherapy in particular. Although adjuvant treatments are routinely guided by predictive factors for endocrine therapy (hormone receptor expression) and anti-HER2 therapy (HER2 overexpression), predicting benefit from chemotherapy has been more challenging. Randomized studies are now in progress utilizing multiparameter gene expression assays that may more accurately select patients most likely to benefit from adjuvant chemotherapy.

  1. Pathobiology of cancer chemotherapy-induced peripheral neuropathy (CIPN

    2013-12-01

    Full Text Available Chemotherapy induced peripheral neuropathy (CIPN is a type of neuropathic pain that is a major dose-limiting side-effect of potentially curative cancer chemotherapy treatment regimens that develops in a ‘stocking and glove’ distribution. When pain is severe, a change to less effective chemotherapy agents may be required, or patients may choose to discontinue treatment. Medications used to alleviate CIPN often lack efficacy and/or have unacceptable side-effects. Hence the unmet medical need for novel analgesics for relief of this painful condition has driven establishment of rodent models of CIPN. New insights on the pathobiology of CIPN gained using these models are discussed in this review. These include mitochondrial dysfunction and oxidative stress that are implicated as key mechanisms in the development of CIPN. Associated structural changes in peripheral nerves include neuronopathy, axonopathy and/or myelinopathy, especially intra-epidermal nerve fiber (IENF degeneration. In patients with CIPN, loss of heat sensitivity is a hallmark symptom due to preferential damage to myelinated primary afferent sensory nerve fibers in the presence or absence of demyelination. The pathobiology of CIPN is complex as cancer chemotherapy treatment regimens frequently involve drug combinations. Adding to this complexity, there are also subtle differences in the pathobiological consequences of commonly used cancer chemotherapy drugs, viz platinum compounds, taxanes, vincristine, bortezomib, thalidomide and ixabepilone, on peripheral nerves.

    Intrathecal chemotherapy and systemic chemotherapy are used for both prophylaxis and treatment of central nervous system disease in hematologic malignancies. However, intrathecal treatment has some adverse effects, such as arachnoiditis, progressive myelopathy, and leukoencephalopathy. The authors describe six children in whom myelopathy and adhesive arachnoiditis developed after administration of intrathecal chemotherapy including methotrexate, cytosine arabinoside, and prednisolone. Urinary retention and incontinence, the main presenting complaints in all patients, developed within 12 hours after intrathecal therapy and spontaneously resolved within 7 days. Two patients were unable to walk. In these two, weakness in the lower extremities gradually recovered by 1 month but urinary incontinence did not improve. None of the children had sensory loss. On follow-up periodic recurrent urinary tract infection was noted in four patients. MRI findings corresponded to arachnoiditis. No response was recorded on tibial nerve somatosensory evoked potentials in all patients. Intrathecal chemotherapy, especially methotrexate, can cause spinal cord dysfunction in children with acute lymphoblastic leukemia and non-Hodgkin's lymphoma. Arachnoiditis should be kept in mind as a causative factor in recurrent urinary tract infection in patients receiving intrathecal chemotherapy.

    Medical institutions are increasingly concerned about ensuring the safety of patients under their care. Failure mode and effect analysis (FMEA) is a qualitative approach based on a proactive process. Strongly promoted by the Joint Commission Accredited of Health Organization (JCAHO) since 2002, FMEA has since been adopted and widely practiced in healthcare organizations to assess and analyze clinical error events. FMEA has proven to be an effective method of minimizing errors in both manufacturing and healthcare industries. It predicts failure points in systems and allows an organization to address proactively the causes of problems and prioritize improvement strategies. The application of FMEA in chemotherapy at our department identified three main failure points: (1) inappropriate chemotherapy standard operating procedures (SOPs), (2) communication barriers, and (3) insufficient training of nurses. The application of FMEA in chemotherapy is expected to enhance the sensitivity and proactive abilities of healthcare practitioners during potentially risky situations as well as to improve levels of patient care safety.

    The application of the Rappaport classification for non-Hodgkin lymphoma has allowed for the stratification of histologic subtypes with consistent clinical correlations. Nodularity imparts a favorable prognosis and response to chemotherapy; diffuse patterns are unfavorable. Fifty percent survivals of 5 to 9 years and 1 to 2 years are observed for nodular and diffuse types, respectively. Single agent chemotherapy is ineffective for the diffuse histologies. Combination chemotherapy results in 20 to 80 percent complete remission rates in patients with mixed cell and poorly differentiated diffuse types; median survivals of 1 to 2 years are achieved. The outlook for diffuse histiocytic lymphoma is optimistic: complete remission rates of 50 to 68 percent are achieved. Flattening of the remission duration curve suggests a significant number of these patients are cured of their disease.

    Full Text Available Myoepithelial carcinoma (malignant myoepithelioma of the breast is a rare tumor, for which only a limited number of reports have been published. Most of the reports emphasized diagnosis and pathology but not biological behavior and treatment. We report a 61-year-old patient with breast myoepithelial carcinoma who developed locoregional and distant metastases and received many chemotherapy regimens. She presented with an elastic hard mass of the left breast. Breast conserving surgery was performed as part of both diagnosis and treatment. From the results of histological and immunohistochemical examinations, this case was considered to be a myoepithelial carcinoma. Fifteen months after the completion of adjuvant radiotherapy, distant metastasis of the left parasternal lymph node metastasis developed. She was treated by further excision and received a total of four regimens of chemotherapy including a combination of doxorubicin and cyclophosphamide. She received chemotherapy for 20 months after the diagnosis of metastasis.

    Gliomas, the most common primary brain tumors, are diffusive and highly invasive. The standard treatment for brain tumors consists of a combination of surgery, radiation therapy and chemotherapy. Over the past few years, mathematical models have been applied to study untreated and treated brain tumors. In an effort to improve treatment strategies, we consider a simple spatio-temporal mathematical model, based on proliferation and diffusion, that incorporates the effects of radiotherapeutic and chemotherapeutic treatments. We study the effects of different schedules of radiation therapy, including fractionated and hyperfractionated external beam radiotherapy, using a generalized linear quadratic (LQ) model. The results are compared with published clinical data. We also discuss the results for combination therapy (radiotherapy plus temozolomide, a new chemotherapy agent), as proposed in recent clinical trials. We use the model to predict optimal sequencing of the postoperative (combination of radiotherapy and adjuvant, neo-adjuvant or concurrent chemotherapy) treatments for brain tumors.

    This analytical, cross-sectional study applied a quantitative approach to verify the presence of depression and the adherence to a chemotherapy treatment in patients with cancer at the central chemotherapy pharmacy of a university hospital. The sample consisted of 102 patients, and data were collected from October 2010 to May 2011. A structured interview was used to obtain sociodemographic, clinical and therapeutic data; the Morisky Test and Beck Depression Inventory were also applied. The results revealed that 10.8% and 1.9% of participants had moderate and severe depression, respectively. The presence of depression was significantly associated with variables such as income per capita, the number of surgeries, and disease duration. A lack of treatment adherence was identified in 48% of participants. These results indicate the need for health staff training to detect depressive disorders and chemotherapy treatment attrition among patients with cancer.

    Systemic chemotherapy treatments, commonly those that comprise oxaliplatin, have been linked to the appearance of distinctive liver lesions that evolves to portal hypertension, spleen enlargement, platelets sequestration, and thrombocytopenia. This outcome can interrupt treatment or force dosage reduction, decreasing efficiency of cancer therapy. We conducted a prospective phase II study for the evaluation of partial splenic embolization in patients with thrombocytopenia that impeded systemic chemotherapy continuation. From August 2014 through July 2015, 33 patients underwent partial splenic embolization to increase platelets count and allow their return to treatment. Primary endpoint was the accomplishment of a thrombocyte level superior to 130 × 10(9) /L and the secondary endpoints were the return to chemotherapy and toxicity. Partial splenic embolization was done 36 times in 33 patients. All patients presented gastrointestinal cancer and colorectal malignancy was the commonest primary site. An average of 6.4 cycles of chemotherapy was done before splenic embolization and the most common regimen was Folfox. Mean platelet count prior to embolization was 69 × 10(9) /L. A total of 94% of patients achieved primary endpoint. All patients in need reinitiated treatment and median time to chemotherapy return was 14 days. No grade 3 or above adverse events were identified. Aiming for a 50% to 70% infarction area may be sufficient to achieve success without the complications associated with more extensive infarction. Combined with the better safety profile, partial splenic embolization is an excellent option in the management of thrombocytopenia, enabling the resumption of systemic chemotherapy with minimal procedure-related morbidity.

    Full Text Available Objective: Evaluate the characteristics of arthritis, arthralgia and musculoskeletal pain after chemotherapy in patients with lung cancer. Materials and Methods: In this study, we evaluate the characteristics of 17 patients with joint symptoms following receiving chemotherapy for lung cancer. Demographic information of patients including sex, age, time of rheumatologic findings after starting of chemotherapy, time of improvement after starting of medication, and relevant laboratory findings for each patient. Results: A total of seventeen patients (six women with mean age 41.2 ± 5.2 years and 11 men with mean age 42.5 ± 8.2 that received standard chemotherapy for lung cancer according to stage of disease. Joint symptoms usually began about seven months after the first session of chemotherapy. Patients had an average of two tender joints and 1 hr of morning stiffness. Four patients were positive for anti-nuclear antibody, and none of patient was positive for rheumatoid factor. Non-steroidal anti-inflammatory drugs, disease modifying anti-rheumatic drugs (DMARD, corticosteroids, and venlafaxine were prescribed. Four patients did not show an improvement. Follow-up was available for all patients. 11 patients showed favorable responses, characterized by a significant decrease (more than 50% in morning stiffness, pain, and tender joint counts after a mean of three months′ treatment. Two patients had complete resolution of symptoms and did not required further medications for arthritis, arthralgia or musculoskeletal pain. Conclusion: Chemotherapy-related arthropathy in lung cancer is not uncommon. Early treatment with NSAID, DMARD, and corticosteroids is effective in the majority of patients.

    Cancer patients who start receiving chemotherapy have difficulty in understanding the state of their disease, the prognosis, and the purpose of treatment. We used a survey to evaluate the extent of perception of chemotherapy goal among cancer patients. Two hundred sixteen cancer patients who received chemotherapy for the first time participated in the study. The presence of depression and anxiety was assessed using the "Hospital Anxiety and Depression Scale" (HAD). The consistency between the patients' perception of the chemotherapy goal and the physician's perception was described as "right," and the inconsistency was described as "wrong." Among the patients who participated in the survey, 53.2 % (n = 115) were receiving adjuvant treatment and 46.8 % (n = 101) were receiving palliative treatment for metastatic disease. The rate of right and wrong perception of the chemotherapy goal was 51.9 % (n = 108) and 32.2 % (n = 67), respectively, and the rate of confused patients was 18.9 % (n = 41). The level of education was shown to be the only parameter involved in accurate perception of the treatment purpose (hazard ratio (HR) = 0.444, p = 0.025, 95 % confidence interval (CI) 0.219-0.903). In this study, there was a 51.9 % consistency between the physician's perception and that of the patient regarding the purpose of treatment. We demonstrated that the level of education was the unique factor in accurate perception of chemotherapy goal among cancer patients.

    Substantial progress has been made in the multidisciplinary management of primary breast cancer during the last 30 years. Adjuvant chemotherapy has been shown to significantly reduce the annual risk of cancer recurrence and mortality, and these effects persist even 15 years after diagnosis. Combination chemotherapy is superior to single-agent therapy and anthracycline-containing regimens. Those that combine an anthracycline with 5-fluorouracil and cyclophosphamide are more effective than regimens without an anthracycline. Six cycles of a single regimen appear to provide optimal benefit. Dose reductions below the standard range are associated with inferior results. Dose increases that require growth factor or hematopoietic stem cell support are under investigation; at this time, the existing results provide no compelling reason to use this strategy outside a clinical trial. Regimens using fixed crossover designs with two non-cross-resistant regimens are being evaluated. The addition of a taxane to anthracycline-containing regimens is currently under intense scrutiny, and preliminary analysis of the first three clinical trials has shown encouraging, albeit not compelling, results. For patients with estrogen receptor-positive breast cancer, the sequential administration of chemotherapy and 5 years of tamoxifen therapy provides additive benefits. No compelling evidence exists to combine ovarian ablation with chemotherapy. Most side effects and toxic effects are self-limited, although premature menopause requires monitoring and preventive interventions to preserve bone mineral density. The small risk of acute leukemia is of concern, and additional research to develop safer regimens is clearly indicated. The overall effect of optimal local/regional treatment combined with an anthracycline-containing adjuvant chemotherapy and a taxane (and, for patients with estrogen receptor-positive tumors, 5 years of tamoxifen therapy) is a greater than 50% reduction in annual risks of

    In the treatment of tumor patients, how to select the chemotherapy regimen with better efifcacy, less toxicity and expense is a difficult problem that perplexes clinical doctors for a long time. Pharmacogenetics is to study the influence of genetic factors on pharmacokinetics, whereas pharmacogenomics is to study the relationship between various gene mutations and drug efifcacy and safety. With molecular biology developing, pharmacogenetics and pharmacogenomics are considered to be essential in the reduction of adverse reactions, improvement of efficacy and realization of individualized treatment. In this article, the clinical application and evaluation of pharmacogenomics in tumor chemotherapy were primarily investigated.

    Full Text Available Background and objective To study the role of postoperative chemotherapy and its prognostic effect in Masaoka-Koga stage III and IV thymic tumors. Methods Between 1994 and 2012, 1,700 patients with thymic tumors who underwent surgery without neoajuvant therapy were enrolled for the study. Among them, 665 patients in Masaoka-Koga stage III and IV were further analyzed to evaluate the clinical value of postoperative chemotherapy. The Kaplan-Meier method was used to obtain the survival curve of the patients divided into different subgroups, and the Cox regression analysis was used to make multivariate analysis on the factors affecting prognosis. A Propensity-Matched Study was used to evaluate the clinical value of chemotherapy. Results Two-hundred-twenty-one patients were treated with postoperative chemotherapy, while the rest 444 cases were not. The two groups showed significant differences (P<0.05 regarding the incidence of myasthenia gravis, World Health Organization (WHO histological subtypes, pathological staging, resection status and the use of postoperative radiotherapy. WHO type C tumors, incomplete resection, and postoperative radiotherapy were significantly related to increased recurrence and worse survival (P<0.05. Five-year and 10-year disease free survivals (DFS and recurrence rates in patients who underwent surgery followed by postoperative chemotherapy were 51% and 30%, 46% and 68%, comparing with 73% and 58%, 26% and 40% in patients who had no adjuvant chemotherapy after surgery (P=0.001, P=0.001, respectively. In propensity-matched study, 158 pairs of patients with or without postoperative chemotherapy (316 patients in total were selected and compared accordingly. Similar 5-year survival rates were detected between the two groups (P=0.332. Conclusion Pathologically higher grade histology, incomplete resection, and postoperative radiotherapy were found to be associated with worse outcomes in advanced stage thymic tumors. At present

Although the transurethral resection of bladder tumor (TURBT followed by intravesical chemotherapy is a conservative strategy for treatment of T1G3 bladder cancer, a relatively high risk of tumor recurrence and progression remains regarding the therapy. This study aimed to compare the efficacy of intravenous chemotherapy combined with intravesical chemotherapy versus intravesical chemotherapy alone for T1G3 bladder cancer after TURBT surgery. Methods: We retrospectively reviewed the cases of 457 patients who were newly diagnosed with T1G3 bladder urothelial carcinoma between January 2009 and March 2014. After TURBT, 281 patients received intravesical chemotherapy alone, whereas 176 patients underwent intravesical chemotherapy in combination with intravenous chemotherapy. Tumor recurrence and progression were monitored periodically by urine cytology and cystoscopy in follow-up. Recurrence-free survival and progression-free survival of the two chemotherapy strategies following TURBT were analyzed. Univariable and multivariable Cox hazards analyses were performed to predict the prognostic factors for tumor recurrence and progression. Results: The tumor recurrence rate was 36.7% for patients who received intravesical chemotherapy alone after TURBT, compared with 19.9% for patients who received intravenous chemotherapy combined with intravesical chemotherapy after

    2013-03-14

    Cancer patients receiving chemotherapy have a high risk of malnutrition secondary to the disease and treatment, and 40-80 % of cancer patients suffer from different degrees of malnutrition, depending on tumour subtype, location, staging and treatment strategy. Malnutrition in cancer patients affects the patient's overall condition, and it increases the number of complications, the adverse effects of chemotherapy and reduces the quality of life. The aim of the present study was to evaluate weight-loss prevalence depending on the tumour site and the gastrointestinal (GI) symptoms of oncology patients receiving chemotherapy. We included 191 cancer patients receiving chemotherapy. Files of all patients were reviewed to identify symptoms that might potentially influence weight loss. The nutritional status of all patients was also determined. The cancer sites in the patients were as follows: breast (31·9 %); non-colorectal GI (18·3 %); colorectal (10·4 %); lung (5·8 %); haematological (13·1 %); others (20·5 %). Of these patients, 58 % experienced some degree of weight loss, and its prevalence was higher among the non-colorectal GI and lung cancer patients. Common symptoms included nausea (59·6 %), anorexia (46 %) and constipation (31·9 %). A higher proportion of patients with ≥ 5 % weight loss experienced anorexia, nausea and vomiting (OR 9·5, 2·15 and 6·1, respectively). In conclusion, these results indicate that GI symptoms can influence weight loss in cancer patients, and they should be included in early nutritional evaluations.

    Postoperative combined modality therapy with radiotherapy and 5-fluorouracil (5FU) chemotherapy is an effective adjuvant approach that reduces locoregional and distant metastatic disease in patients with high-risk rectal carcinoma. However, this approach results in a treatment regimen of at least 6 months` duration. The present prospective study investigates the integration of radiotherapy and 5FU chemotherapy in a protocol designed to minimize toxicity and reduce the overall treatment time. A total of 40 patients with TNM stage 11 or 111 disease receives postoperative radiotherapy at four fractions per week with weekly 5FU bolus injections delivered on the fifth non radiotherapy day. Patients also received systemic chemotherapy with leucovorin both before and after pelvic irradiation, with the total treatment duration extending for only 18 weeks. Patients were able to complete radiotherapy in 90% of cases, while the delivery of full-dose chemotherapy was achievable in the vast majority. The incidence of haematologic and gastrointestinal toxicities requiring the cessation of treatment was acceptable. With a median follow-up of 20.9 months among surviving patients, the estimated progression-free and overall survival at 2 years were 71% and 79%, respectively.

    AIM: To assess the efficacy and safety of intraperitoneal chemotherapy in patients undergoing curative resection for gastric cancer through literature review. METHODS: Medline (PubMed) (1980-2003/1), Embase (1980-2003/1), Cancerlit Database (1983-2003/1) and Chinese Biomedicine Database (1990-2003/1) were searched. Language was restricted to Chinese and English. The statistical analysis was performed by RevMan4.2 software provided by the Cochrane Collaboration. The results were expressed with odds ratio for the categorical variables. RESULTS: Eleven trials involving 1 161 cases were included. The pooled odds ratio was 0.51, with a 95% confidence interval (0.40-0.65). Intraperitoneal chemotherapy may benefit the patients after curative resection for locally advanced gastric cancer, and the combination of intraperitoneal chemotherapy with hyperthermia or activated carbon particles may provide more benefits to patients due to the enhanced antitumor activity of drugs. Sensitivity analysis and fail-safe number suggested that the result was comparatively reliable. However, of 11 trials, only 3 studies were of high quality. CONCLUSION: Intraperitoneal chemotherapy after curative resection for locally advanced gastric cancer may be beneficial to patients. Continuous multicenter, randomized, double blind, rigorously designed trials should be conducted to draw definitive conclusions.

    Peritoneal surface malignancies are generally associated with poor prognosis.In daily clinical routine,systemic chemotherapy is still considered the only reasonable therapy despite of encouraging results of cytoreductive surgery (CRS) along with intraperitoneal hyperthermic chemotherapy (HIPEC).The Achilles heel of CRS and HIPEC is appropriate patient selection and precise surgical technique preventing patients from excessive morbidity and mortality.Given these findings,new concepts of second look surgery for high risk patients allow detection of peritoneal spread ahead of clinical symptoms or presence of peritoneal masses reducing perioperative morbidity.In addition,personalized intraperitoneal chemotherapy might further improve outcome by appreciating individual tumor biology.These days,every physician should be aware of CRS and HIPEC for treatment of peritoneal surface malignancies.Since there is now sufficient data for the superiority of CRS and HIPEC to systemic chemotherapy in selected patients,our next goal should be providing this strategy with minimal morbidity and mortality even in the presence of higher tumor load.

    Chemotherapy-induced enteropathy (CIE) is one of the most serious complications of anticancer therapy, and tools for its early detection and monitoring are highly needed. We report on a novel fluorescence method for detection of CIE, based on molecular imaging of the related apoptotic process. The method comprises systemic intravenous administration of the ApoSense fluorescent biomarker (N,N'-didansyl-L-cystine DDC) in vivo and subsequent fluorescence imaging of the intestinal mucosa. In the reported proof-of-concept studies, mice were treated with either taxol+cyclophosphamide or doxil. DDC was administered in vivo at various time points after drug administration, and tracer uptake by ileum tissue was subsequently evaluated by ex vivo fluorescent microscopy. Chemotherapy caused marked and selective uptake of DDC in ileal epithelial cells, in correlation with other hallmarks of apoptosis (i.e., DNA fragmentation and Annexin-V binding). Induction of DDC uptake occurred early after chemotherapy, and its temporal profile was parallel to that of the apoptotic process, as assessed histologically. DDC may therefore serve as a useful tool for detection of CIE. Future potential integration of this method with fluorescent endoscopic techniques, or development of radio-labeled derivatives of DDC for emission tomography, may advance early diagnosis and monitoring of this severe adverse effect of chemotherapy.

    In August 1982, a 44-year-old man was diagnosed as having rectal cancer, histologically diagnosed as well differentiated adenocarcinoma, and abdominoperineal resection and colostomy were performed. Postoperatively, he received chemotherapy with mitomycin C up to a total dose of 100 mg. In September 1986, lung metastasis occurred and he was treated with a combination chemotherapy consisting of cisplatin, pirarubicin and 5-fluorouracil. In the following year, radiation treatment (total: 6900 rad) was given for a recurrent pelvic lesion. Peripheral blood on April 30, 1988, showed anemia, thrombocytopenia and appearance of myeloblasts, and a diagnosis of acute myelogenous leukemia (FAB: M1) was made. Combination chemotherapy (including aclarubicin, vincristine, behenoyl ara-C, daunorubicin, 6-mercaptopurine, cytarabine, etoposide and prednisolone) failed to induce remission and the patient died in June 1988. This case was thought to be one of secondary leukemia occurring after chemotherapy and radiation treatment for rectal cancer. This case clearly indicates the need for a careful follow-up of long-term survivors who have received cancer therapy. (author).

    2009-04-01

    Full Text Available Almost all clinically used antitumor drugs exhibit toxic side effects affecting heart function. Because of cardiotoxicity during anticancer chemotherapy, effective doses of cytostatics have to be limited, which may worsen antitumor efficacy. The cardiotoxicity induced by cytostatics of the anthracycline group in particular results, among others, from massive stimulation of ROS. It has therefore been suggested that some phytochemicals with high antioxidant potential, when administered together with antitumor agents, could decrease the toxic side effects of chemotherapy and reduce the risk of heart failure. This review summarizes findings of studies undertaken to identify edible plants or phytochemicals isolated from them displaying cardioprotective properties during chemotherapy. Such properties have been shown for such foods as grapes, garlic, tomato, spinach, and beetroot. A protective role on the heart is also displayed by melatonin (a hormone synthesized by the pineal gland, but also present in many edible plants, chalcones (precursors of all known flavonoids, some herbal dietary supplements, vitamins A, C, and E, selenium, and semisynthetic flavonoid 7-monohydroxyethylrutoside (monoHER. Although to date only a limited number of investigations have been carried out, their results suggest that dietary intervention with antioxidants found in edible plants may be a safe and effective way of alleviating the toxicity of anticancer chemotherapy and preventing heart failure.

    Some techniques of the most recent interventional radiology are very useful for the treatment of metastatic liver cancer and changing the style of hepatic infusion chemotherapy. This report shows our latest results and methods of hepatic infusion chemotherapy for metastatic liver cancer. 1. For the catheter placement, a new catheterization route via the left subclavian artery into the hepatic artery was developed and performed in 132 cases. Superselective catheterization succeeded in 123 cases (93.2%). This procedure is less invasive than laparotomy and less troublesome than other percutaneous routes. 2. For useful infusion system, an implantable injection port ''Reservoir'' was developed and it was used in 87 cases. This method makes arterial infusion chemotherapy easy, and imploves their quality of life. 3. To acquire adequate drug delivery, arterial redistribution by steel coils was done, and 109 arteries in 80 cases were occluded. This method is very useful to make multiple hepatic artery single and it is important to avoid gasroduodenal complications. 4. Now, using these techniques, the phase II study of 5FU, ADM, MMC combined hepatic infusion in patients with non-resectable metastatic liver cancer is done. Up to this time, such a phase study on arterial infusion chemotherapy was difficult because of technical problems, but these new techniques make it possible. In conclusion, these new methods change the style and conception of hepatic infusion, and these make much progress on the treatment of patients with metastatic liver cancer.

    Objective: To evaluate the risk of neoadjuvant chemotherapy for surgical morbidity after mastectomy with or without reconstruction using 1:1 matching. Background: Postoperative surgical complications remain a potentially preventable event for breast cancer patients undergoing mastectomy. Neoadjuvant chemotherapy is among variables identified as contributory to risk, but it has not been rigorously evaluated as a principal causal influence. Methods: Data from American College of Surgeons National Surgical Quality Improvement Program (2006–2012) were used to identify females with invasive breast cancer undergoing planned mastectomy. Surgical cases categorized as clean and undergoing no secondary procedures unrelated to mastectomy were included. A 1:1 matched propensity analysis was performed using neoadjuvant chemotherapy within 30 days of surgery as treatment. A total of 12 preoperative variables were used with additional procedure matching: bilateral mastectomy, nodal surgery, tissue, and/or implant. Outcomes examined were 4 wound occurrences, sepsis, and unplanned return to the operating room. Results: We identified 31,130 patient procedures with 2488 (7.5%) receiving chemotherapy. We matched 2411 cases, with probability of treatment being 0.005 to 0.470 in both cohorts. Superficial wound complication was the most common wound event, 2.24% in neoadjuvant-treated versus 2.45% in those that were not (P = 0.627). The rate of return to the operating room was 5.7% in the neoadjuvant group versus 5.2% in those that were not (P = 0.445). The rate of sepsis was 0.37% in the neoadjuvant group versus 0.46% in those that were not (P = 0.654). Conclusions: This large, matched cohort study, controlled for preoperative risk factors and most importantly for the surgical procedure performed, demonstrates that breast cancer patients receiving neoadjuvant chemotherapy have no increased risk for surgical morbidity.

    Nausea and vomiting are among the most serious side effects of chemotherapy, in some cases leading to treatment interruption or chemotherapy dose reduction. Ginger has long been known as an antiemetic drug, used for conditions such as motion sickness, nausea-vomiting in pregnancy, and post-operation side effects. One hundred and fifty female patients with breast cancer entered this prospective study and were randomized to receive ginger (500 mg ginger powder, twice a day for 3 days) or placebo. One hundred and nineteen patients completed the study: 57 of them received ginger and 62 received ginger for the frst 3 chemotherapy cycles. Mean age in all patients was 48.6 (25-79) years. After 1st chemotherapy, mean nausea in the ginger and control arms were 1.36 (±1.31) and 1.46 (±1.28) with no statistically significant difference. After the 2nd chemotherapy session, nausea score was slightly more in the ginger group (1.36 versus 1.32). After 3rd chemotherapy, mean nausea severity in control group was less than ginger group [1.37 (±1.14), versus 1.42 (±1.30)]. Considering all patients, nausea was slightly more severe in ginger arm. In ginger arm mean nausea score was 1.42 (±0.96) and in control arm it was 1.40 (±0.92). Mean vomiting scores after chemotherapy in ginger arm were 0.719 (±1.03), 0.68 (±1.00) and 0.77 (±1.18). In control arm, mean vomiting was 0.983 (±1.23), 1.03 (±1.22) and 1.15 (±1.27). In all sessions, ginger decreased vomiting severity from 1.4 (±1.04) to 0.71 (±0.86). None of the differences were significant. In those patients who received the AC regimen, vomiting was less severe (0.64±0.87) compared to those who received placebo (1.13±1.12), which was statistically significant (p-value <0.05). Further and larger studies are needed to draw conclusions.

  7. From total empiricism to a rational design of metronomic chemotherapy phase I dosing trials.

    'Metronomic chemotherapy' represents a novel anti-angiogenic strategy whereby low-dose chemotherapy is utilized in a continuous fashion in order to target tumor endothelium. There are many potential advantages of this strategy and clinical trials are already underway. However, although the scheduling of metronomic chemotherapy is relatively unequivocal, metronomic dosing principles are at present poorly defined. Arbitrarily, 10-33% of the maximum tolerated dose comprises 'the dose range'. We argue that this is too empirical and propose a set of phase I metronomic chemotherapy dosing strategies based on a principled approach which may help to reduce the problem of empiricism in dosing for metronomic chemotherapy trials.

    Full Text Available Background : Chemotherapy-induced nausea (CIN in the anticipatory and acute phase is the most common side effect in cancer therapy. The purpose of this study was to investigate the effect of ginger capsules on the alleviation of this problem. Methods : This randomized, double-blind, placebo-controlled clinical trial was performed on 80 women with breast cancer between August till December 2009 in Imam Khomeini Hospital, Tehran, Iran. These patients underwent one-day chemotherapy regime and suffering from chemotherapy-induced nausea. After obtaining written consent, samples were randomly assigned into intervention and control groups. Two groups were matched based on the age and emetic effects of chemotherapy drugs used. The intervention group received ginger capsules (250 mg, orally four times a day (1 gr/d and the same samples from the placebo group received starch capsules (250 mg, orally for three days before to three days after chemotherapy. To measure the effect of capsules a three-part questionnaire was used, so the samples filled every night out these tools. After collecting the information, the gathered data were analyzed by statistical tests like Fisher’s exact, Kruskal-Wallis and Chi-square using version 8 of STATA software. Results : The mean ± SD of age in the intervention and placebo groups were 41.8 ± 8.4 and 45.1 ± 10 years, respectively. Results indicated that the severity and number of nausea in the anticipatory phase were significantly lower in the ginger group compared with placebo group (P=0.0008, P=0.0007, respectively. Also, the intensity (P=0.0001 and number (P=0.0001 of nausea in the acute phase were significantly lower in the ginger group. On the other hand, taking ginger capsules compared with placebo did not result in any major complications. Conclusion: Consuming ginger root powder capsules (1 gr/d from three days before chemotherapy till three days after it in combination with the standard anti-emetic regimen can

    Objective: Through investigating the influence of neoadjuvant intraarterial infusion chemotherapy (NIAC) on the timing changes of apoptosis, PCNA and multiple drug resistance associated genes of endometrial cancer, to study the mechanism of chemotherapy and to define the best operation time. Methods: Twenty patients were subjected to neoadjuvant consecutive uterine arterial infusion with CDDP 100 mg and ADM 50 mg. The biopsy of endometrial tumor tissues was performed before, immediate after and 1, 2-2+3 w, 3+3-4 w after chemotherapy. Apoptosis index (AI) was estimated by a combination of histologic and TUNEL assays. Proliferative index (PI) was examined by SABC immunohistochemical staining. Expressions of multidrug resistance 1 (MDR1), multidrug resistance-associated protein (MRP) and lung resistance protein (LRP) were detected by reverse transcription polymerase chain reaction (RT-PCR). Results: The AI of endometrial cancer cells immediate after and 1, 2-2+3 w, after chemotherapy were 3.03%, 3.47% and 5.04%, respectively, much higher than that before chemotherapy which was 2.31%. After chemotherapy, AI/PI gradually increased. It was highest in 2-2+3 w, while 3+3-4 w after chemotherapy the AI and AI/PI were both significantly lower than that before chemotherapy. The expression of MDR1, MRP and LRP all decreased temporarily after chemotherapy, while 3+3-4 w after chemotherapy they all increased to levels higher than that before chemotherapy, but the difference were not significant (P>0.05). Conclusion: Neoadjuvant consecutive intra-arterial infusion chemotherapy via uterine artery can inhibit tumor cells proliferation and induce apoptosis effectively. To evaluate the response of intra-arterial chemotherapy the change of apoptosis index and cell proliferation should be analyzed. The most suitable time for the operation is 3 weeks after intra-arterial infusion chemotherapy.

    2014-03-15

    Purpose: To estimate the radiation equivalent of the chemotherapy contribution to observed complete response rates in published results of 1-phase radio-chemotherapy of muscle-invasive bladder cancer. Methods and Materials: A standard logistic dose–response curve was fitted to data from radiation therapy-alone trials and then used as the platform from which to quantify the chemotherapy contribution in 1-phase radio-chemotherapy trials. Two possible mechanisms of chemotherapy effect were assumed (1) a fixed radiation-independent contribution to local control; or (2) a fixed degree of chemotherapy-induced radiosensitization. A combination of both mechanisms was also considered. Results: The respective best-fit values of the independent chemotherapy-induced complete response (CCR) and radiosensitization (s) coefficients were 0.40 (95% confidence interval −0.07 to 0.87) and 1.30 (95% confidence interval 0.86-1.70). Independent chemotherapy effect was slightly favored by the analysis, and the derived CCR value was consistent with reports of pathologic complete response rates seen in neoadjuvant chemotherapy-alone treatments of muscle-invasive bladder cancer. The radiation equivalent of the CCR was 36.3 Gy. Conclusion: Although the data points in the analyzed radio-chemotherapy studies are widely dispersed (largely on account of the diverse range of chemotherapy schedules used), it is nonetheless possible to fit plausible-looking response curves. The methodology used here is based on a standard technique for analyzing dose-response in radiation therapy-alone studies and is capable of application to other mixed-modality treatment combinations involving radiation therapy.

    Full Text Available Intrathecal chemotherapy is routinely prescribed in medical oncology practice, either for prophylaxis or for treatment of leptomeningeal disease due to a primary haematological disease or a metastatic disease due to any other malignancy. As these groups of patients are coagulopathic either because of the disease per se or due to systemic chemotherapy, lumbar puncture in them is considered challenging and is expected to be performed by an anaesthesiologist because of their expertise in this procedure. However, the challenge is not only in performing the lumbar puncture safely but also in dealing with other issues like explaining and handling complications that can happen either due to the drug injected intrathecally or due to a neurodeficit occurring either due to the underlying coagulopathy or due to the progression of leptomeningeal disease.

    Combination chemotherapy is widely exploited for enhanced cancer treatment in the clinic. However, the traditional cocktail administration of combination regimens often suffers from varying pharmacokinetics among different drugs. The emergence of nanotechnology offers an unparalleled opportunity for developing advanced combination drug delivery strategies with the ability to encapsulate various drugs simultaneously and unify the pharmacokinetics of each drug. This review surveys the most recent advances in combination delivery of multiple small molecule chemotherapeutics using nanocarriers. The mechanisms underlying combination chemotherapy, including the synergistic, additive and potentiation effects, are also discussed with typical examples. We further highlight the sequential and site-specific co-delivery strategies, which provide new guidelines for development of programmable combination drug delivery systems. Clinical outlook and challenges are also discussed in the end.

  16. Nutritional problems among patients affected by cancer during chemotherapy

    Directory of Open Access Journals (Sweden)

    Marzena Kamińska

    2016-01-01

    Full Text Available Chemotherapy is one of the primary methods of treating cancer. Symptoms occurring during this form of therapy affect patients’ general health status, cause malnutrition, and deteriorate the quality of life of oncology patients, which results in cachexia. Malnutrition during treatment and the resulting bad general health status of patients may lead to disqualification from chemotherapy treatment. Cachexia is a complex and multi-factorial process, characterised by the nearly unknown mechanism of its development. What is extremely crucial is the evaluation of the state of malnutrition among patients qualified for cytostatic therapy and regular control of this state during therapy and immediately after its termination. Clinical practice indicates the importance of applying pharmacotherapy, nutritional treatment, and targeted education for the patient and their closest family regarding diet and correct behaviour, which significantly reduces anxiety and stress.

    Twenty four children aged 2 to 13 years who were to receive cancer chemotherapy were enrolled in a prospective study (before-after-trial) in order to evaluate the efficacy of systematic antiemetic prophylaxis. The regimen of three drugs (metilpednisolone 4 mg/Kg/dose/iv 2 doses; metodopamide 0.5 mg/Kg/dose/iv 4 doses; diphenydramine 1 mg/Kg/dose/iv 4 doses) was used. We found a significative reduction (P less than 0.001) in the incidence of vomiting and nauseousness duration when the antiemetic prophylaxis was used. There were very few and slight adverse effects secondary to antiemetic drugs: Sedation happened in 25% of chemotherapic cycles and hypotension without clinical repercussion in 15%. No patient had distonia. We conclude that systematical antiemetic protection should be used in children receiving chemotherapy. The association of metilpednisolone, metopramide and diphenhydramine is a safe and effective combination.

    The development of curative chemotherapy regimens for the treatment of Hodgkin’s lymphoma is one of the true success stories in oncology. Most patients diagnosed with Hodgkin’s lymphoma today can be cured. The major task remaining before us is curing as many patients as possible with their initial therapeutic approach while minimizing the acute toxicities and limiting the lifetime risks of important secondary events such as cardiovascular complications and secondary malignancies.

    Cytoreductive surgery and Hyperthermic Intraperitoneal Chemotherapy have achieved good long-term results in patients with complete surgical eradication of their peritoneal dissemination but at the expense of significant perioperative morbidity and mortality. The high complication rate has been attributed to the steep learning curve associated with this procedure. We report on the current literature regarding the learning curve for this procedure and the key components that determine the success in learning this new skill.

    Full Text Available Introduction: Intrathecal chemotherapy is frequently used in clinical practice for treatment and prevention of neoplastic meningitis. Despite its widespread use, there is little information about practical aspects such as the volume of drug to be administered or its preparation and administration. Objective: To conduct a literature review about practical aspects of the use of intrathecal chemotherapy. Materials: Search in PubMed/ Medline using the terms chemotherapy AND intrathecal”, analysis of secondary and tertiary information sources. Results: The most widely used drugs in intrathecal therapy are methotrexate and cytarabine, at variable doses. One of the aspects with higher variability among different studies is their potential combination with a glucocorticoid, the specific corticoid selected and its dose. The efficacy and toxicity of the different combinations have not been compared. Regarding preparation, it is worth highlighting the recommendation to adjust pH and osmolarity to the physiological range, with the aim of improving tolerability. The volume of administration can influence distribution, and recommendated range is between 5 and 12 mL. Overall, it is recommended to extract a similar volume of cerebrospinal fluid before administration. The position of the patient during and after administration can have an impact on distribution and toxicity; lateral decubitus or sitting position is recommended in the first case, and prone and/ or supine position in the second one. Most publications don’t explain how the treatment has been prepared or administered, and the lack of standardization could affect results. Conclusions: There is a great variability in practice when using intrathecal chemotherapy, despite being an effective therapy, accepted by all international groups. This uncertainty is not li mited to the drugs and doses administered, but it also includes the manner of preparation and the administration technique. The

    Objective: Chemotherapy is an effective means of treating breast cancer, and cancer-specific replicative adenovirus is also a promising antitumor agent in recent years. Our investigation aims to demonstrate that CNHK300 can mediate selective antitumor efficacy and produce synergistic cytotoxicity with chemotherapy on HER-2 over-expressing breast cancer. Methods: We engineered the telomerase-dependent replicative adenovirus CNHK300 by placing the E1A gene under the control of the human hTERT promoter. By analysis of E1A expression, we proved the fidelity of hTERT promoter in adenovirus genome and the selective expression of E1A in telomerase-positive breast cancer cells but not in normal fibroblast cells. By proliferation test, we further showed efficient replication of CNHK300 in breast cancer cells with apparently attenuated proliferation in normal fibroblast cells. Finally, we demonstrated by MTT methods that CNHK300 virus caused potent cytolysis and produced synergistic cytotoxicity with chemotherapy in breast cancer cells with attenuated cytotoxicity on normal cells. Results: In this virus, the E1A gene is successfully placed under the control of the human hTERT promoter. CNHK300 virus replicated as efficiently as the wild-type adenovirus and caused intensive cell killing in HER-2 over-expressing breast cancer cells in vitro. In contrast, telomerase-negative normal fibroblast cells, which expressed no hTERT activity, were not able to support CNHK300 replication. Combined treatment of CNHK300 with paclitaxel improved cytotoxicity on cancer cells. Conclusion: We conclude that CNHK300 can produce selective antitumor efficacy and enhance the in vitro response of chemotherapy on HER-2 overexpressing breast cancer.

    We studied efficacy of a combination of intraosseous and systemic administration of drugs in patients with invasive cancer of the urinary bladder (UB). A total of 20 patients aged 54-79 years with verified had recurrence, 2 had tumors with continuous growth. T2N0M0 UB carcinoma was diagnosed in 7 patients, T3N0M0--in 12, T6N0M0--in 1 patient. All the patients received systemic chemotherapy with gemzar in a single daily dose 800-1000 mg/m2 on day 1, 7 and 14. On day 2 a single intraosseous 100 mg eloxatin was given. A total of three courses of combined chemotherapy with 4-week interval was used. Intravenous gemzar administration was accompanied with mild leukopenia in 4 patients, moderate leukopenia--in 1, allergic reaction--in 2 patients. This required gemzar discontinuation. No side effects were seen in response to intraosseous administration of eloxatin. The combined chemotherapy produced complete regression of UB cancer in 3 of 18 patients, partial regression--in 12, stabilization--in 3 patients. Neither local nor long-term tumor progression was found. Short-term therapeutic efficacy of combined therapy was 70%. Fifteen patients with partial regression or stabilization have undergone transurethral resection. Duration of a recurrence-free period reached 5 to 72 months (mean 17 months). The neoadjuvant chemotherapy proposed by us allows achievement of a high percentage of regression in patients with invasive UB cancer located in UB cervix and provides concervative surgery including patients over 70 years of age.

    Full Text Available CONTEXT: Totally implantable devices are increasingly being utilized for chemotherapy treatment of oncological patients, although few studies have been done in our environment to analyze the results obtained from the implantation and utilization of such catheters. OBJECTIVE: To study the results obtained from the implantation of totally implantable catheters in patients submitted to chemotherapy. TYPE OF STUDY: Prospective. SETTING: Hospital do Câncer A.C. Camargo, São Paulo, Brazil. METHODS: 519 totally implantable catheters were placed in 500 patients submitted to chemotherapy, with preference for the use of the right external jugular vein. Evaluations were made of the early and late-stage complications and patient evolution until removal of the device, death or the end of the treatment. RESULTS: The prospective analysis showed an average duration of 353 days for the catheters. There were 427 (82.2% catheters with no complications. Among the early complications observed, there were 15 pathway hematomas, 8 cases of thrombophlebitis of the distal stump of the external jugular vein and one case of pocket infection. Among the late-stage complications observed, there were 43 infectious complications (0.23/1000 days of catheter use, 11 obstructions (0.06/1000 days of catheter use and 14 cases of deep vein thrombosis (0.07/1000 days of catheter use. Removal of 101 catheters was performed: 35 due to complications and 66 upon terminating the treatment. A total of 240 patients died while the catheter was functioning and 178 patients are still making use of the catheter. CONCLUSION: The low rate of complications obtained in this study confirms the safety and convenience of the use of totally implantable accesses in patients undergoing prolonged chemotherapy regimes.

    Full Text Available Chemoradiotherapy is increasingly used in advanced laryngeal cancers. Failures are generally managed by surgery. They include histologically confirmed recurrent or residual disease or a symptomatic life threatening treatment sequelae. Tumour recurrence or residivism can be managed by chemotherapy when radical surgery is either refused by the patient or if the general condition of the patient do not permit it. However surgery becomes inevitable when life threatening treatment sequelae like absolute pharyngo-oesophageal stricture and aspiration sets in.

    Bacteria induce urinary crystallization of struvite and carbonate-apatite as a by-product of ureolysis by urease. Eradication of infection and/or inhibition of urease with acetohydroxamic acid for 5 to 30 months retarded stone growth and brought about partial or comple dissolution of stones in 9 patients. Long-term chemotherapy with antimicrobial agents that achieve steril urine or acetohydroxamic acid in those patients with recalcitrant infection lessens the risk of recurrent calculogenesis.

    Chemotherapy with anthracyclines and trastuzumab can cause cardiotoxicity. Alteration of cardiac adrenergic function assessed by metaiodobenzylguanidine labeled with iodine-123 ({sup 123}I-mIBG) seems to precede the drop in left ventricular ejection fraction. To evaluate and to compare the presence of cardiovascular abnormalities among patients with breast cancer undergoing chemotherapy with anthracyclines and trastuzumab, and only with anthracycline. Patients with breast cancer were analyzed clinical, laboratory, electrocardiographic and echocardiographic and cardiac sympathetic activity. In scintigraphic images, the ratio of {sup 123}I-mIBG uptake between the heart and mediastinum, and the washout rate were calculated. The variables were compared between patients who received anthracyclines and trastuzumab (Group 1) and only anthracyclines (Group 2). Twenty patients, with mean age 57 ± 14 years, were studied. The mean left ventricular ejection fraction by echocardiography was 67.8 ± 4.0%. Mean washout rate was 28.39 ± 9.23% and the ratio of {sup 123}I-mIBG uptake between the heart and mediastinum was 2.07 ± 0.28. Of the patients, 82% showed an increased in washout rate, and the ratio of {sup 123}I-mIBG uptake between the heart and mediastinum decreased in 25%. Concerning the groups, the mean washout rate of Group 1 was 32.68 ± 9.30% and of Group 2 was 24.56 ± 7.72% (p = 0,06). The ratio of {sup 123}I-mIBG uptake between the heart and mediastinum was normal in all patients in Group 2, however, the Group 1, showed 50% the ratio of {sup 123}I-mIBG uptake between the heart and mediastinum ≤ 1.8 (p = 0.02). In women with breast cancer undergoing chemotherapy, assessment of cardiac sympathetic activity with {sup 123}I-mIBG appears to be an early marker of cardiotoxicity. The combination of chemotherapy showed higher risk of cardiac adrenergic hyperactivity.

    Although cytoreductive surgery (CRS) and hyperthermic perioperative chemotherapy (HIPEC) have not been shown to be effective by themselves, as a combined treatment they are now standard of care for peritoneal metastases from appendiceal cancer and from colorectal cancer as well as peritoneal mesothelioma. The timing of the HIPEC in relation to the CRS is crucial in that the HIPEC is to destroy minimal residual disease that remains following the CRS and prevent microscopic tumor emboli within the abdomen and pelvis from implanting within the resection site, within fibrinous clot, or within blood clot. Proper selection of chemotherapy agents is crucial to the long-term benefit of CRS and HIPEC. One must consider the response expected with the cancer chemotherapy agent, its area under the curve (AUC) ratio indicating the amount of dose intensity within the peritoneal space, and the drug retention within the peritoneal space for a prolonged exposure. Hyperthermia will augment the cytotoxicity of the cancer chemotherapy agents and improve drug penetration. Irrigation techniques should not be overlooked as an important means of reducing the cancer cell burden within the abdomen and pelvis. Multiple technologies for HIPEC exist and these have advantages and disadvantages. The techniques vary from a totally open technique with a vapor barrier over the open abdominal space to a totally closed technique whereby the HIPEC is administered at the completion of the surgical procedure. The open techniques depend on a table-mounted retractor for suspension of the skin edges allowing a reservoir to occur within the abdomen and pelvis. There are nearly a dozen commercially available hyperthermia pumps, all of which seem to perform adequately for HIPEC although there is a variable degree of convenience and documentation of the HIPEC procedure. As the management of peritoneal metastases has progressed over three decades, early cases are now seen in which a laparoscopic CRS and HIPEC

    To evaluate the complete pathologic response attained by patients diagnosed with locally advanced breast cancer submitted to neoadjuvant chemotherapy based on the doxorubicin/ cyclophosphamide regimen followed by paclitaxel. A retrospective cohort of patients with locally advanced breast cancer, admitted to the Hospital de Câncer de Barretos between 2006 and 2008 submitted to the doxorubicin/cyclophosphamide protocol followed by paclitaxel (4 cycles of doxorubicin 60mg/m{sup 2} and cyclophosphamide 600mg/m{sup 2} every 21 days; 4 cycles of paclitaxel 175mg/m{sup 2} every 21 days). The following variables were assessed: age, menopause, performance status, initial clinical staging, anthropometric data, chemotherapy (dose – duration), toxicity profile, post-treatment staging, surgery, pathologic complete response rate, disease-free survival, and pathological characteristics (type and histological degree, hormonal profile and lymph node involvement). Statistical analysis was performed using a 5% level of significance. Of the 434 patients evaluated, 136 were excluded due to error in staging or because they had received another type of chemotherapy. Median age was 50 years, all with performance status 0-1. Median initial clinical size of tumor was 65mm and the median final clinical size of the tumor was 22mm. Fifty-one (17.1%) patients experienced a pathologic complete response. Those with a negative hormonal profile or who were triple-negative (negative Her-2 and hormonal profile) experienced a favorable impact on the pathologic complete response. Neoadjuvant chemotherapy with doxorubicin/ cyclophosphamide followed by paclitaxel provided a pathologic complete response in the population studied in accordance with that observed in the literature. Triple-negative patients had a greater chance of attaining this response.

    Chemotherapy regimens for pancreatic ductal adenocarcinoma (PDAC) have changed since the introduction of FOLFIRINOX. Due to toxicity, dosage and number of applied cycles are limited. In analogy to chemotherapy strategies in colon cancer we used a scheme of induction, maintenance and re-induction therapy in PDAC to alleviate such toxicities and increase the number of applied cycles. Here we report first experiences with this approach. Data of all patients who received FOLFIRINOX for metastatic or locally advanced PDAC in our center using induction chemotherapy followed by maintenance therapy from 2011 until November 2016 was collected and analyzed retrospectively. Progression free survival was assessed starting induction therapy until progressive disease (PD) during maintenance or treatment pause (PFS1) and until progression during re-induction therapy (PFS2). 13 patients received induction therapy which was followed by maintenance therapy. Re-induction due to PD during therapy was applied in 11 patients. The median PFS1 was 10.6 months (95% CI; 6.7-14.4), PFS2 was 14.1 months (95% CI; 8.2-19.9) and overall survival was 18.3 months (95% CI; 14.8-21.8). The use of FOLFIRINOX as induction, followed by maintenance and re-induction therapy in case of PD is feasible in the treatment of PDAC and might lead to a prolonged PFS with less toxicity.

    2017-03-01

    One of the major complaints patients who survive cancer often make is chemotherapy induced cognitive impairment (CICI), which survivors often call "chemo brain." CICI is a side effect of chemotherapy due to the cytotoxicity and neurotoxicity of anti-cancer drugs causing structural and functional changes in brain, even when drugs that do not cross the blood brain barrier (BBB) are used. Diminished cognitive functions including diminution of learning and memory, concentration and attention, processing speed and executive functions that reduce quality of life and ability to work are common signs and symptoms of CICI. There still is not a clarified and complete mechanism for CICI, but researchers have pointed to several biochemical candidates. Chemotherapy-induced, cytokine-mediated involvement in CICI will be mainly discussed in this review paper with emphasis on different types of cytokines, correlated with BBB and epigenetic changes. Mechanisms of ROS-generating, anti-cancer drugs and their relation to cytokine-mediated CICI will be emphasized.

    Chemotherapy is a widely accepted method for tumour treatment. A medical doctor usually treats patients periodically with an amount of drug according to empirical medicine guides. From the point of view of cybernetics, this procedure is an impulse control system, where the amount and frequency of drug used can be determined analytically using the impulse control theory. In this paper, the stability of a chemotherapy treatment of a tumour is analysed applying the impulse control theory. The globally stable condition for prescription of a periodic oscillatory chemotherapeutic agent is derived. The permanence of the solution of the treatment process is verified using the Lyapunov function and the comparison theorem. Finally, we provide the values for the strength and the time interval that the chemotherapeutic agent needs to be applied such that the proposed impulse chemotherapy can eliminate the tumour cells and preserve the immune cells. The results given in the paper provide an analytical formula to guide medical doctors to choose the theoretical minimum amount of drug to treat the cancer and prevent harming the patients because of over-treating.This article is part of the themed issue 'Horizons of cybernetical physics'.

    Pulmonary veno-occlusive disease (PVOD) is an uncommon form of pulmonary hypertension (PH) characterized by progressive obstruction of small pulmonary veins and a dismal prognosis. Limited case series have reported a possible association between different chemotherapeutic agents and PVOD. We evaluated the relationship between chemotherapeutic agents and PVOD. Cases of chemotherapy-induced PVOD from the French PH network and literature were reviewed. Consequences of chemotherapy exposure on the pulmonary vasculature and hemodynamics were investigated in three different animal models (mouse, rat, and rabbit). Thirty-seven cases of chemotherapy-associated PVOD were identified in the French PH network and systematic literature analysis. Exposure to alkylating agents was observed in 83.8% of cases, mostly represented by cyclophosphamide (43.2%). In three different animal models, cyclophosphamide was able to induce PH on the basis of hemodynamic, morphological, and biological parameters. In these models, histopathological assessment confirmed significant pulmonary venous involvement highly suggestive of PVOD. Together, clinical data and animal models demonstrated a plausible cause-effect relationship between alkylating agents and PVOD. Clinicians should be aware of this uncommon, but severe, pulmonary vascular complication of alkylating agents.

  16. 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.

    Full Text Available In this paper, a design method for optimal cancer chemotherapy schedules via genetic algorithm (GA is presented. The design targets the key objective of chemotherapy to minimize the size of cancer tumor after a predefined time with keeping toxic side effects in limit. This is a difficult target to achieve using conventional clinical methods due to poor therapeutic indices of existing anti-cancer drugs. Moreover, there are clinical limitations in treatment administration to maintain continuous treatment. Besides, carefully decided rest periods are recommended to for patient’s comfort. Three intermittent drug scheduling schemes are presented in this paper where GA is used to optimize the dose quantities and timings by satisfying several treatment constraints. All three schemes are found to be effective in total elimination of cancer tumor after an agreed treatment length. The number of cancer cells is found zero at the end of the treatment for all three cases with tolerable toxicity. Finally, two of the schemes, “Fixed interval variable dose (FIVD and “Periodic dose” that are periodic in characteristic have been emphasized due to their additional simplicity in administration along with friendliness to patients. responses to the designed treatment schedules. Therefore the proposed design method is capable of planning effective, simple, patient friendly and acceptable chemotherapy schedules.

  18. Impact of Temozolomide on Immune Response during Malignant Glioma Chemotherapy

    2012-01-01

    Full Text Available Malignant glioma, or glioblastoma, is the most common and lethal form of brain tumor with a median survival time of 15 months. The established therapeutic regimen includes a tripartite therapy of surgical resection followed by radiation and temozolomide (TMZ chemotherapy, concurrently with radiation and then as an adjuvant. TMZ, a DNA alkylating agent, is the most successful antiglioma drug and has added several months to the life expectancy of malignant glioma patients. However, TMZ is also responsible for inducing lymphopenia and myelosuppression in malignant glioma patients undergoing chemotherapy. Although TMZ-induced lymphopenia has been attributed to facilitate antitumor vaccination studies by inducing passive immune response, in general lymphopenic conditions have been associated with poor immune surveillance leading to opportunistic infections in glioma patients, as well as disrupting active antiglioma immune response by depleting both T and NK cells. Deletion of O6-methylguanine-DNA-methyltransferase (MGMT activity, a DNA repair enzyme, by temozolomide has been determined to be the cause of lymphopenia. Drug-resistant mutation of the MGMT protein has been shown to render chemoprotection against TMZ. The immune modulating role of TMZ during glioma chemotherapy and possible mechanisms to establish a strong TMZ-resistant immune response have been discussed.

    Choosing the optimal chemotherapy regimen is still an unmet medical need for breast cancer patients. In this study, we reanalyzed data from seven independent data sets with totally 1079 breast cancer patients. The patients were treated with three different types of commonly used neoadjuvant chemotherapies: anthracycline alone, anthracycline plus paclitaxel, and anthracycline plus docetaxel. We developed random forest models with variable selection using both genetic and clinical variables to predict the response of a patient using pCR (pathological complete response) as the measure of response. The models were then used to reassign an optimal regimen to each patient to maximize the chance of pCR. An independent validation was performed where each independent study was left out during model building and later used for validation. The expected pCR rates of our method are significantly higher than the rates of the best treatments for all the seven independent studies. A validation study on 21 breast cancer cell lines showed that our prediction agrees with their drug-sensitivity profiles. In conclusion, the new strategy, called PRES (Personalized REgimen Selection), may significantly increase response rates for breast cancer patients, especially those with HER2 and ER negative tumors, who will receive one of the widely-accepted chemotherapy regimens.

  20. Simultaneous radiochemotherapy in cervical cancer: recommendations for chemotherapy

    Energy Technology Data Exchange (ETDEWEB)

    Dunst, J.; Haensgen, G. [Halle Univ., Wittenberg (Germany). Dept. of Radiotherapy

    2001-12-01

    Background: Simultaneous radiochemotherapy has recently been demonstrated to be superior to radiation alone in the treatment of cervical cancer. The objective of this article is to summarize the data of major randomized trials and to derive recommendations for daily clinical practice. Materials and Methods: We have analyzed the data from seven randomized trials in the recent literature in which radiotherapy alone as standard treatment has been compared to simultaneous radiochemotherapy. Four trials used cisplatin-based chemotherapy regimens, 5-FU, mitomycin C and epirubicin were used each in one trial. Results: All trials demonstrated some improvement in survival which was significant in the studies with cisplatin-based chemotherapy regimens. The survival benefit resulted mainly from an improvement in local control whereas chemotherapy had only a small and insignificant effect on distant metastases. Thus, the main action of chemotherapy is ''radiosensitization''. Cisplatin as single drug yielded comparable results as compared to combined regimens although the cisplatin dose was lower in the studies with combination chemotherapy. For the definitive treatment of locally advanced cancers, monotherapy with cisplatin can be recommended. Mitomycin C offers an attractive alternative to cisplatin in patients with contraindications for cisplatin. For postoperative radiochemotherapy, a combination of cisplatin/5-FU should be used because data with cisplatin alone are lacking so far. Simultaneous radiochemotherapy should also be considered for the curative treatment of local recurrences. Conclusions: The addition of simultaneous chemotherapy to radiotherapy is indicated in the vast majority of patients with cervical cancers who are treated with curative intent. (orig.)

    Full Text Available Seigo Minami, Yoshitaka Ogata, Shouichi Ihara, Suguru Yamamoto, Kiyoshi Komuta Department of Respiratory Medicine, Osaka Police Hospital, Osaka, Japan Background: Small-cell lung cancer (SCLC is responsive to initial chemotherapy but becomes resistant to cytotoxic drugs. The aim of this study was to evaluate what proportion of patients with SCLC had received the first- and further-line chemotherapy and which patients had benefited from chemotherapy. Methods: We retrospectively reviewed medical records of patients with SCLC who had been treated with the best supportive care alone and the first-, second-, or third-line chemotherapy at the Osaka Police Hospital from June 2007 until March 2015. Results: Among 145 patients diagnosed with SCLC and eligible for analysis, 118 patients received chemotherapy. We added five patients who initiated the second-line chemotherapy during the study period at our institution. Sixty-five and 31 patients received the second- and third-line chemotherapies, respectively. Multivariate logistic regression analysis detected age ≥75 years (odds ratio, 2.80; 95% confidence interval, 1.01–7.75; P=0.047 and European Clinical Oncology Group Performance Status (ECOG PS 3–4 (14.3; 4.86–41.9; P<0.01 as factors disturbing the introduction of chemotherapy. Multivariate Cox hazard analyses also detected ECOG PS 2–4 (3.34; 2.00–5.58; P<0.01 as a factor decreasing overall survival after the first-line chemotherapy, and C-reactive protein level ≥1.0 mg/dL (2.67; 1.30–5.47; P<0.01 and progression-free survival after the first-line chemotherapy ≥6 months (2.85; 1.50–5.43; P<0.01 as factors influencing overall survival after the second-line chemotherapy.

    Full Text Available Abstract Background The molecular changes in vivo in acute myeloid leukemia cells early after start of conventional genotoxic chemotherapy are incompletely understood, and it is not known if early molecular modulations reflect clinical response. Methods The gene expression was examined by whole genome 44 k oligo microarrays and 12 k cDNA microarrays in peripheral blood leukocytes collected from seven leukemia patients before treatment, 2–4 h and 18–24 h after start of chemotherapy and validated by real-time quantitative PCR. Statistically significantly upregulated genes were classified using gene ontology (GO terms. Parallel samples were examined by flow cytometry for apoptosis by annexin V-binding and the expression of selected proteins were confirmed by immunoblotting. Results Significant differential modulation of 151 genes were found at 4 h after start of induction therapy with cytarabine and anthracycline, including significant overexpression of 31 genes associated with p53 regulation. Within 4 h of chemotherapy the BCL2/BAX and BCL2/PUMA ratio were attenuated in proapoptotic direction. FLT3 mutations indicated that non-responders (5/7 patients, 8 versus 49 months survival are characterized by a unique gene response profile before and at 4 h. At 18–24 h after chemotherapy, the gene expression of p53 target genes was attenuated, while genes involved in chemoresistance, cytarabine detoxification, chemokine networks and T cell receptor were prominent. No signs of apoptosis were observed in the collected cells, suggesting the treated patients as a physiological source of pre-apoptotic cells. Conclusion Pre-apoptotic gene expression can be monitored within hours after start of chemotherapy in patients with acute myeloid leukemia, and may be useful in future determination of therapy responders. The low number of patients and the heterogeneity of acute myeloid leukemia limited the identification of gene expression predictive of therapy

    In over the 10 years from 2000-2010, 21 gastric cancer patients received loco-regional chemotherapy with home enteral nutrition (HEN) at an outpatient clinic because of insufficient oral intake. These loco-regional chemotherapy regimens consisted of 5 intra-aortic chemotherapies, 4 hepato-arterial infusions and 12 intra-peritoneal chemotherapies. Five out of 8 cases that had measurable lesions showed PR, and 3 cases revealed PD. The patients received HEN with peptide central formula, 400-1,200 kcal/day in night time. The average duration of HEN was 12.9 months. The post-operative nutritional management was needed for continuation and securing of outpatient chemotherapy. The author reported an experience of the outpatient loco-regional chemotherapy with HEN for the gastric cancer patients who could not eat a sufficient volume of food.

    2009-12-01

    Full Text Available Abstract Background Vascular complications occurring during cisplatin-based chemotherapy of germ cell tumours are inadequately recognized to date. Case Presentation A 49 year old man with advanced seminoma underwent two courses of chemotherapy according to the PEB regimen. Upon restaging, two thrombotic deposits were noted in the descending part of the thoracic aorta and in the infrarenal abdominal aorta, respectively. Although thrombotic plaques caused aortic occlusion of about 30%, no clinical signs of malperfusion of limbs were registered. The patient was placed on anticoagulant therapy. Six months after completion of chemotherapy, thrombotic deposits had completely resolved. In the absence of other predisposing factors, it must be assumed that cisplatin-based chemotherapy represented a strong stimulus for arterial thrombosis in the aorta. Conclusions This is the first case of endo-aortic thrombosis during chemotherapy for testicular germ cell cancer. Providers of chemotherapy must be aware of arterial thrombosis even in young patients with testicular cancer.

    Drug resistance is a major problem in anticancer therapy. ATP-binding cassette (ABC) transporters have a role in the multidrug resistance. A new regimen of chemotherapy has been proposed, called "metronomic chemotherapy". Metronomic chemotherapy is the frequent, regular administration of drug doses designed to maintain low, but active, concentrations of chemotherapeutic drugs over prolonged periods of time, without causing serious toxicities. Metronomic chemotherapy regimens were developed to optimize the antitumor efficacy of agents that target the tumor vasculature instead of tumor cells, and to reduce toxicity of antineoplastic drugs [1]. Nevertheless, recent studies revealed that ABC transporters are expressed at a higher level in the endothelium in the tumor. To avoid resistance to metronomic anti-angiogenic chemotherapy, ABC transporter inhibition of tumor endothelial cells may be a promising strategy. In this mini-review, we discuss the possible mechanism of resistance to metronomic chemotherapy from the viewpoint of tumor endothelial cell biology, focusing on ABC transporters.

    Objective: Through observing the clinical response to neoadjuvant intraarterial chemotherapy in locally advanced cervical cancer and investigating the changes of p53 protein expression, proliferation and apoptosis of tumor cells after chemotherapy, to study the relationship between biological markers and chemotherapeutic response. Methods: 20 women with locally advanced squamous cervical cancer received consecutive infusion chemotherapy of five days of cisplatin and adriamycin via the superselective uterine artery. The response to chemotherapy was evaluated by gynecologic examination and ultrasonography 3 weeks after chemotherapy. The changes of apoptotic index (AI), proliferation index (PI) and p53 expression of tumor cells were detected by immunohistochemical technique. Results: The clinical response rate of locally advanced squamous cervical cancer to uterine artery infusion chemotherapy was 70%. No change of PI was found 3 weeks after treatment, but AI significantly increased from 2.79±0.76 to 4.29±1.13 (P<0.01), and AI/PI from 5.68±1.21 to 9.00±1.95 (P<0.05). On the contrary, the expression of p53 was significantly decreased (P<0.05). Patients who responded to chemotherapy showed higher PI before chemotherapy and significantly increased AI and AI/PI after chemotherapy than non-responders (P<0.05). Conclusion: Higher PI was an indication for neoadjuvant intraarterial chemotherapy. One more cycle of chemotherapy should be given to those who have significantly increased AI or AI/PI after chemotherapy, while definite treatment such as surgery or/and radiotherapy should be immediately given to those patients without increased AI or AI/PI.

    A prospective observational study was conducted in a male orphanage to find out the prevalence of enterobiasis and its incidence after blanket chemotherapy using mebendazole. We found that the prevalence of enterobiasis was 28.9%. The incidence density of enterobiasis after blanket chemotherapy was 379.82 per 1,000 person-years which was quite high. We suggest that blanket chemotherapy should be repeated at every 6 months interval to control enterobiasis in orphanages.

    Delayed gastric emptying symptoms are often reported after chemotherapy. This study aims to characterise the effects of chemotherapy on gastric neuro-muscular function. Patients undergoing elective surgery for oesophago-gastric cancer were recruited. Acetylcholinesterase, nNOS, ghrelin receptor and motilin expressions were studied in gastric sections from patients receiving no chemotherapy (n = 3) or oesophageal (n = 2) or gastric (n = 2) chemotherapy. A scoring system quantified staining intensity (0-3; no staining to strong). Stomach sections were separately suspended in tissue baths for electrical field stimulation (EFS) and exposure to erythromycin or carbachol; three patients had no chemotherapy; four completed cisplatin-based chemotherapy within 6 weeks prior to surgery. AChE expression was markedly decreased after chemotherapy (scores 2.3 ± 0.7, 0.5 ± 0.2 and 0 ± 0 in non-chemotherapy, oesophageal- and gastric-chemotherapy groups (p gastric function.

    To examine the effect of suboptimal chemotherapy in patients undergoing preoperative chemoradiotherapy for the treatment of rectal cancer. The medical records of 43 patients who received preoperative concurrent chemoradiotherapy, followed by radical surgery for the treatment of pathologically proven adenocarcinoma of the rectum from April 2003 to April 2006 were retrospectively reviewed. The delivered radiation dose ranged from 41.4 to 50.4 Gy. The standard group consisted of patients receiving two cycles of a 5-FU bolus injection for three days on the first and fifth week of radiotherapy or twice daily with capecitabine. The standard group included six patients for each regimen. The non-standard group consisted of patients receiving one cycle of 5-FU bolus injection for three days on the first week of radiotherapy. The non-standard group included 31 patients. Radical surgery was performed at a median of 58 days after the end of radiotherapy. A low anterior resection was performed in 36 patients, whereas an abdominoperineal resection was performed in 7 patients. No significant difference was observed between the groups with respect to pathologic responses ranging from grades 3 to 5 (83.3% vs. 67.7%, p=0.456), downstaging (75.0% vs. 67.7%, p=0.727), and a radial resection margin greater than 2 mm (66.7% vs. 83.9%, p=0.237). The sphincter-saving surgery rate in low-lying rectal cancers was lower in the non-standard group (100% vs. 75%, p=0.068). There was no grade 3 or higher toxicity observed in all patients. Considering that the sphincter-saving surgery rate in low-lying rectal cancer was marginally lower for patients treated with non-standard, suboptimal chemotherapy, and that toxicity higher than grade 2 was not observed in the both groups, suboptimal chemotherapy should be avoided in this setting.

  19. Application of biodynamic imaging for personalized chemotherapy in canine lymphoma

    Science.gov (United States)

    Custead, Michelle R.

    Biodynamic imaging (BDI) is a novel phenotypic cancer profiling technology which characterizes changes in cellular and subcellular motion in living tumor tissue samples following in vitro or ex vivo treatment with chemotherapeutics. The ability of BDI to predict clinical response to single-agent doxorubicin chemotherapy was tested in ten dogs with naturally-occurring non-Hodgkin's lymphomas (NHL). Pre-treatment tumor biopsy samples were obtained from all dogs and treated with doxorubicin (10 muM) ex vivo. BDI captured cellular and subcellular motility measures on all biopsy samples at baseline and at regular intervals for 9 hours following drug application. All dogs subsequently received treatment with a standard single-agent doxorubicin protocol. Objective response (OR) to doxorubicin and progression-free survival time (PFST) following chemotherapy were recorded for all dogs. The dynamic biomarkers measured by BDI were entered into a multivariate logistic model to determine the extent to which BDI predicted OR and PFST following doxorubicin therapy. The model showed that the sensitivity, specificity, and accuracy of BDI for predicting treatment outcome were 95%, 91%, and 93%, respectively. To account for possible over-fitting of data to the predictive model, cross-validation with a one-left-out analysis was performed, and the adjusted sensitivity, specificity, and accuracy following this analysis were 93%, 87%, and 91%, respectively. These findings suggest that BDI can predict, with high accuracy, treatment outcome following single-agent doxorubicin chemotherapy in a relevant spontaneous canine cancer model, and is a promising novel technology for advancing personalized cancer medicine.

    Full Text Available Background and Aim: Nausea and vomiting are the most common side effects of chemotherapy. The aim of the current study was to assess the effect of ice massage applied to the pericardium 6 (P6 or Neigaun acupuncture point on nausea– vomiting due to chemotherapy in cancer patient. Materials and Methods: In a randomized clinical trial one- blind, 114 patients were randomly divided into three groups. Ice massage group were massaged gently on the skin around P6 point of the hand with ice cube into a wet gauze pad for 7 minutes twice a day with 12-hours interval for 24 hours by the patient. Placebo group were massaged with wooden cube and the control group received no interventions. Nausea and vomiting in three groups rated by Morrow Assessment of Nausea and Emesis (MANE Questionnaire in 4 periods of time in 24 hours was used for the assessment of nausea and vomiting. Results: There were significant decreases in the frequency of nausea (P<0.01 and vomiting (P<0.03 and a decrease in the intensity of nausea (P=0.63 and vomiting (P=0.34 in the case group. Frequency of nausea was significantly lower among placebo group than the control group (P<0.02. Conclusion: Ice massage on Neigaun point is effective on reducing the frequency of chemotherapy induced nausea and vomiting in cancer patients. Placebos, patient-practitioner relationship, suggestion, and the patient's view on nausea and vomiting and the role of interaction between the therapist and the patient is effective to some extent.

    The aim of this study was to investigate the utility of pulmonary rehabilitation for improving of exercises efficiency, dyspnea, and quality of life of patients with lung cancer during chemotherapy. After the enrollment selection, the study included 20 patients with newly diagnosed advanced lung cancer and performance status 0-2. There were 12 patients randomly allocated to the pulmonary rehabilitation group and another 8 constituted the control group that did not undergo physical rehabilitation. Both groups of patients had continual cycles of chemotherapy. Data were analyzed before and after 8 weeks of physical rehabilitation, and before and after 8 weeks of observation without rehabilitation in controls. The inpatient rehabilitation program was based on exercise training with ski poles and respiratory muscle training. We found a tendency for enhanced mobility (6 Minute Walk Test: 527.3 ± 107.4 vs. 563.9 ±64.6 m; p > 0.05) and a significant increase in forced expired volume in 1 s (66.9 ± 13.2 vs. 78.4 ± 17.7 %predicted; p = 0.016), less dyspnea (p = 0.05), and a tendency for improvement in the general quality of life questionnaire after completion of pulmonary rehabilitation as compared with the control group. This report suggests that pulmonary rehabilitation in advanced lung cancer patients during chemotherapy is a beneficial intervention to reduce dyspnea and enhance the quality of life and mobility.

    Complex, multidrug chemotherapy protocols commonly are administered to patients with cancer. At every step of the chemotherapy administration process, from the point that chemotherapy is ordered to the point that it is infused and beyond, potential for error exists. FMEA, a proactive process that promotes systematic thinking about the safety of patient care, is a risk analysis technique that can be used to evaluate the process of chemotherapy administration. Error prevention is an ongoing quality improvement process that requires institutional commitment and support, and nurses play a vital role in the process.

    Abstract This study aimed to determine the prognostic effects of preoperative chemotherapy for colorectal cancer liver metastasis (CLM). We retrospectively evaluated 2 groups of patients between January 2006 and August 2012. A total of 53 patients who had ≥3 hepatic metastases underwent resection after preoperative chemotherapy (preoperative chemotherapy group), whereas 96 patients who had ≥3 hepatic metastases underwent resection with a curative intent before chemotherapy for CLM (primary resection group). A propensity score (PS) model was used to compare the both groups. The 3-year disease-free survival (DFS) rates were 31.7% and 20.4% in the preoperative chemotherapy and primary resection groups, respectively (log-rank = 0.015). Analyzing 32 PS matched pairs, we found that the DFS rate was significantly higher in the preoperative chemotherapy group than in the primary resection group (3-year DFS rates were 34.2% and 16.8%, respectively [log-rank = 0.019]). Preoperative chemotherapy group patients had better DFSs than primary resection group patients in various multivariate analyses, including crude, multivariable, average treatment effect with inverse probability of treatment weighting model and PS matching. Responses to chemotherapy are as important as achieving complete resection in cases of multiple hepatic metastases. Preoperative chemotherapy may therefore be preferentially considered for patients who experience difficulty undergoing complete resection for multiple hepatic metastases. PMID:28207557

    Full Text Available Burkitt lymphoma of stomach is among the most rapidly growing gastric cancersassociated with several gasterointestinal symptoms including hematemesis, anorexia, vomiting and etc. Gastric perforation in patients with Burkitt lymphoma of stomach is a very rare condition especially after chemotherapy. We herein present a 21-year old man who was kwon case of gastric Burkitt lymphoma who had undergone chemotherapy and presented with acute onset gastric pain and tenderness. He was diagnosed to suffer from perforated gastric lymphoma for which laparotomy and total gastrectomy was performed. Treatment was continued by chemotherapy. Closed observation is thus recommended for those patients with gastric Burkitt lymphoma undergoing chemotherapy.

    Three pediatric patients with tumors (two rhabdomyosarcoma, one Wilms tumor) had significant focal defects on Tc-99m sulfur colloid scans while receiving chemotherapy (all three had received chemotherapy, including actinomycin D, within ten days prior to scanning). In all three, the defects resolved spontaneously; one biopsy showed fibrosis of a mild degree. The finding of defects on liver scans of pediatric patients receiving chemotherapy must not be automatically assumed to be metastatic disease; the changes may relate to hepatic response to recently administered chemotherapy.

    We performed this study to evaluate the impact of chemotherapy on the outcomes associated with immediate autologous tissue reconstruction (IATR) in the treatment of breast cancer. Patients were divided into two groups: Group 1 received chemotherapy before surgery and Group 2 did not receive chemotherapy. Records were reviewed to identify demographics, comorbidities, histology, and wound healing complications. Groups were compared using Kruskal-Wallis and Fisher exact tests as appropriate. A total of 128 patients were identified: 29 received chemotherapy before surgery (Group 1) and 99 did not receive chemotherapy (Group 2). Group 1 patients were more likely to have diabetes 27 per cent versus 6 per cent (P = 0.005) despite both groups having a mean body mass index of 30. Group 2 patients had less advanced stage disease as expected because they did not receive chemotherapy; 37 per cent of Group 2 patients had stage 0 breast cancer (P < 0.001). The incidence of wound complications was 17 per cent in Group 1 and 12 per cent in Group 2 (P = NS). Preoperative chemotherapy for breast cancer followed by IATR was associated with no increased risk of healing complications. IATR can be offered to patients who require preoperative chemotherapy, and their healing will not be impaired as a result of the chemotherapy.

    Chemotherapy-induced neutropenia is a common complication in cancer treatment. In this study, we investigated chemotherapy-induced neutropenia that was recently detected in all patients with gynecologic malignancy. Between January 2009 and December 2011, we examined cases of chemotherapy-induced neutropenia reported in our hospital. We analyzed the incidence and clinical features of chemotherapy-induced neutropenia and febrile neutropenia in patients with gynecologic malignancy. During the study period, we administered over 1614 infusions (29 regimens) to 291 patients. The median age of the patients was 60 years (range 24-84 years). Chemotherapy-induced neutropenia occurred in 147 (50.5%) patients over 378 (23.4%) chemotherapy cycles. Febrile neutropenia occurred in 20 (6.9%) patients over 25 (1.5%) cycles. The mean duration of neutropenia and fever was 3.6 days (range 1-12 days) and 3.4 days (range 1-9 days), respectively. The source of fever was unexplained by examination or cultures in 14 (56.0%) cycles. There were two cases of neutropenia-related death. Chemotherapy-induced neutropenia was associated with older age (over 70 years) (PFebrile neutropenia was associated with poor performance status (Pneutropenia nor febrile neutropenia was associated with bone marrow metastases or previous radiotherapy. By identifying risk factors for febrile neutropenia, such as performance status, no previous chemotherapy, disseminated disease, and distant metastatic disease, the safe management of chemotherapy-induced neutropenia may be possible in patients with gynecologic malignancy.

    Full Text Available Temozolomide is an imidazotetrazine derivative of the alkylating agent, which is used to treat central nervous system tumors, especially malignant brain gliomas. It is a milestone in brain giloma chemotherapy. Recently, some researchers used temozolomide for the treatment of other tumors, including melanoma, intracranial metastatic tumors, lymphomas, refractory leukaemia, pituitary tumors, lung cancer, and so on. Some results are encouraging in clinical trials. Here, this paper makes a review on the antineoplastic mechanisms of temozolomide, its indications in gliomas and some unusual indications.

    AIM:To investigate the efficacy of hepatic arterial infusion chemotherapy (HAIC) using floxuridine (FUDR)in patients with advanced hepatocellular carcinoma (HCC) confined to the liver.METHODS:Thirty-four patients who had advanced HCC with unresectability or unsuccessful previous therapy in the absence of extrahepatic metastasis were treated with intra-arterial FUDR chemotherapy at our hospital between March 2005 and May 2008.Among the 34 patients,9 patients were classified as Child class C,and 18 patients had portal vein tumor thrombus (PVTT).One course of chemotherapy consisted of continuous infusion of FUDR (0.3 mg/kg during day 1-14) and dexamethasone (10 mg on day 1,4,7 and 11),and this treatment was repeated every 28 d.RESULTS:Two patients (5.9%) displayed a complete response,and 12 patients (35.3%) had a partial response.The tumor control rate was 61.8%.The median overall survival times were 15.3 mo,12.4 mo and 4.3 mo for the patients who were classified as Child class A,Child class B and Child class C,respectively (P =0.0392).The progression-free survival was 12.9mo,7.7 mo and 2.6 mo for the patients who were classified as Child class A,Child class B and Child class C,respectively (P =0.0443).The cumulative survival differed significantly according to the Child-Pugh classification and the presence of PVTT.In addition to hepatic reserve capacity and PVTT,the extent of HCC was an independent factor in determining a poor prognosis.The most common adverse reactions to HAIC were mucositis,diarrhea and peptic ulcer disease,but most of these complications were improved by medical treatment and/or a delay of HAIC.CONCLUSION:The present study demonstrates that intra-arterial FUDR chemotherapy is a safe and effective treatment for advanced HCC that is recalcitrant to other therapeutic modalities,even in patients with advanced cirrhosis.

    Chemotherapy for early stage breast cancer has significantly improved survival outcomes but is associated with ovarian toxicity, resulting in early menopause for many premenopausal women. A qualitative study was conducted that generated a grounded theory explaining how women carried on with life in response to breast cancer and menopause. My purpose in this article is to describe three distinct types of responses from women in that study: making the best of it, struggling and barely noticing. The degree of menopausal symptom distress and perceived level of preparation for the menopause experience had the greatest influence on the type of response.

    Full Text Available Acute acalculous cholecystitis is a rare complication in the treatment of acute myeloblastic leukemia. Diagnosis of acute acalculous cholecystitis remains difficult during neutropenic period. We present two acute myeloblastic leukemia patients that developed acute acalculous cholecystitis during chemotherapy-induced neutropenia. They suffered from fever, vomiting and acute pain in the epigastrium. Ultrasound demonstrated an acalculous gallbladder. Surgical management was required in one patient and conservative treatment was attempted in the other patient. None treatment measures were effective and two patients died. Acute acalculous cholecystitis is a serious complication in neutropenic patients. Earlier diagnosis could have expedited the management of these patients.

    Primary systemic treatment of breast cancer with cytotoxics yields a high response rate and allows conservative surgical procedures in bulky tumours. In order to maximise local control of disease, two innovations were introduced in a pilot study. The first was to identify the good responders after three cycles of chemotherapy and to treat them with three additional cycles. The second was to also give this group of patients a full dose of radiotherapy before surgery with the aim of verifying the rate of pathological complete remissions in view of a possible treatment of breast primary with chemoradiotherapy only. Patients were treated with doxorubicin 60 mg/m{sup 2} and cyclophosphamide, 600 mg/m{sup 2} both intravenously on day 1, every 21 days for three courses. Partial or complete responders received three more courses followed by radiotherapy (50 Gy plus a 10 Gy boost). The others underwent immediate surgery. A total of 32 patients (median age, 50 years; range 28-69 years); performance status, 0-1; T{sub 2} 22, T{sub 3} 8, T{sub 4} 2) were enrolled and were evaluable for response and side-effects. 9 patients had only three cycles of chemotherapy due to absence of response and 23 patients had six cycles of chemotherapy. Overall, 7 patients had a complete remission, 16 a partial remission and 9 had stable disease, for an overall response rate of 72% (95% confidence interval 53-86%). In the group of patients that completed the programme, two complete pathological remissions were observed and 5 patients had only microfoci of tumour. No toxic death or grade III-IV toxicities were observed. Mild or moderate side-effects included mucositis, nausea/vomiting and leucopenia. In conclusion, our results indicate that the addition of radiotherapy to pre-operative chemotherapy did not significantly enhance the incidence of pathological complete remissions. New primary treatment approaches should be explored in this subset of patients in order to improve outcome. (Copyright (c

    Full Text Available Cyclophosphamide therapy may rarely cause pigmentation of the nails which is of different patterns. We report a patient who developed pigmentation of nails after six cycles of cyclophosphamide, methotrexate, and 5-flourouracil chemotherapy, each repeated after 28 days for breast cancer. The patient developed nail pigmentation that started proximally and spread distally and involved all the nails of both hands and feet except the second and third toenails of right foot. Using Naranjo ADR Probability Scale, the case revealed a "probable" association with cyclophosphamide.

  19. Merkel Cell Carcinoma: Chemotherapy and Emerging New Therapeutic Options

    2013-01-01

    Full Text Available Merkel cell carcinoma (MCC is a rare neuroendocrine skin tumor that typically occurs in elderly, immunosuppressed patients. Infection with Merkel cell virus (MCV and immunosuppression play an important role in the development of MCC. Different staging systems make it difficult to compare the existing clinical data. Furthermore, there predominantly exist single case reports and case series, but no randomized controlled trials. However, it is necessary to develop further therapy options because MCC tends to grow rapidly and metastasizes early. In the metastatic disease, therapeutic attempts were made with various chemotherapeutic combination regimens. Because of the high toxicity of these combinations, especially those established in SCLC, and regarding the unsatisfying results, the challenge is to balance the pros and cons of chemotherapy individually and carefully. Up to now, emerging new therapy options as molecular-targeted agents, for example, pazopanib, imatinib, or somatostatin analogues as well as immunologicals, for example, imiquimod and interferons, also showed less success concerning the disease-free response rates. According to the literature, neither chemotherapy nor molecular-targeted agents or immunotherapeutic strategies have shown promising effects in the therapy of the metastatic disease of MCC so far. There is a great demand for randomized controlled studies and a need for an MCC registry and multicenter clinical trials due to the tumors curiosity.

    Mediastinal germ cell tumours (MGCT) are rare and most published series reflect the experiences of individual institutions over many years. Since 1979, we have treated 16 men (12 non-seminomatous germ cell tumours and 4 seminomas) with newly diagnosed primary MGCT with POMB/ACE chemotherapy and elective surgical resection of residual masses. This approach yielded complete remissions in 15/16 (94%) patients. The median follow-up was 6.0 years and no relapses occurred more than 2 years after treatment. The 5 year overall survival in the non-seminomatous germ cell tumours (NSGCT) is 73% (95% confidence interval 43-90%). One patient with NSGCT developed drug-resistant disease and died without achieving remission and 2 patients died of relapsed disease. In addition, 4 patients with bulky and/or metastatic seminoma were treated with POMB/ACE. One died of treatment-related neutropenic sepsis in complete remission and one died of relapsed disease. Finally, 4 patients (2 NSGCT and 2 seminomas) referred at relapse were treated with POMB/ACE and one was successfully salvaged. The combination of POMB/ACE chemotherapy and surgery is effective management for MGCT producing high long-term survival rates.

  1. Role of ABC transporters in fluoropyrimidine-based chemotherapy response.

    Since over 50 years, 5-fluorouracil (5-FU) is in use as backbone of chemotherapy treatment regimens for a wide range of cancers including colon, breast, and head and neck carcinomas. However, drug resistance and severe toxicities such as mucositis, diarrhea, neutropenia, and vomiting in up to 40% of treated patients often lead to dose limitation or treatment discontinuation. Because the oral bioavailability of 5-FU is unpredictable and highly variable, 5-FU is commonly administered intravenously. To overcome medical complications and inconvenience associated with intravenous administration, the oral prodrugs capecitabine and tegafur have been developed. Both fluoropyrimidines are metabolically converted intracellularly to 5-FU, which then needs metabolic activation to exert its damaging activity on RNA and DNA. The low response rates of 10-15% of 5-FU monotherapy can be improved by combination regimens of infusional 5-FU and leucovorin together with oxaliplatin (FOLFOX) or irinotecan (FOLFIRI), thereby increasing response rates to 30-40%. The impact of metabolizing enzymes in the development of fluoropyrimidine toxicity and resistance has been studied in great detail. In addition, membrane drug transporters, which are critical determinants of intracellular drug concentrations, may play a role in occurrence of toxicity and development of resistance against fluoropyrimidine-based therapy as well. This review therefore summarizes current knowledge on the role of drug transporters with particular focus on ATP-binding cassette transporters in fluoropyrimidine-based chemotherapy response.

    Malignant ascites is a common symptom in patientswith peritoneal cancer. Current assumption is that anincreased vascular permeability and obstruction oflymphatic channels lead to the accumulation of fluidin the abdominal cavity. This case report describes aseverely symptomatic patient with malignant ascites.The previously healthy 73-year-old male was presentedwith abdominal distention causing respiratory distress.Computed tomography revealed large amounts ofascites, a recto-sigmoidal mass with locoregionallymphadenopathy and an omental cake. Biopsy takenduring colonoscopy revealed an adenocarcinoma ofthe colon with signet cell differentiation. A widespreadperitoneal carcinomatosis was found during a diagnosticlaparoscopy. The extent of peritoneal diseaserendered the patient not suitable for cytoreductivesurgery with curative intent. The ascites proved to berefractory to ultrasound-guided paracentesis; thus, adecision was made to perform palliative hyperthermicintraperitoneal chemotherapy without cytoreductivesurgery. Consequently, ascites production stopped,and the respiratory distress was relieved thereafter.The postoperative recovery was uneventful. Ascitesrecurred eight months later, and a second hyperthermicintraperitoneal chemotherapy procedure was performed.The patient was still alive at the time of writing, 16 moafter the initial diagnosis.

  3. Pulmonary Fibrosis Secondary to FOLFOX Chemotherapy: A Case Report

    2014-09-01

    Full Text Available A 54-year-old female presented with a 2-week history of increasing shortness of breath and fever. She had a history of a poorly differentiated sigmoid adenocarcinoma for which she underwent an anterior resection 6 months prior to admission, followed by 12 cycles of adjuvant FOLFOX chemotherapy. The patient was treated for a severe community-acquired pneumonia; however, she remained hypoxic. A chest CT revealed extensive right-sided fibrotic changes, tractional dilatation of the airways and ground glass density, which had developed since a staging CT scan performed 2 months previously. Although her symptoms improved with steroid therapy, repeat imaging revealed that right hydropneumothorax had developed, and this required the insertion of a chest drain. Following its successful removal, the patient continues to improve clinically and radiographically. The rapid onset and nature of these changes is consistent with a drug-induced fibrotic lung disease secondary to FOLFOX chemotherapy. The phenomenon is underreported and yet, it is relatively common: it occurs in approximately 10% of patients who are treated with antineoplastic agents, although information specifically relating to FOLFOX-induced pulmonary toxicity is limited. It is associated with significant morbidity and mortality, but is often hard to differentiate from other lung conditions, making the diagnosis a challenge. Pulmonary toxicity is an important complication associated with antineoplastic agents. It should be considered in any patient on a chemotherapeutic regimen who presents with dyspnoea and hypoxia in order to try to reduce the associated morbidity and mortality.

    Full Text Available Background: Chemotherapy induced nausea and vomiting is an added distress to patients burdened by the illness. In an effort to tackle the emetogenic potential of the agents, guidelines have been proposed to maintain uniformity in prescription and improvement in patient tolerance; but their utility and practice is not consistent. The aim of this clinical audit was to assess the antiemetic.practice and investigate the adherence to antiemetic clinical practice guidelineMethods: We performed an audit of the antiemetic practices in our tertiary referral centre. A.questionnaire based interview was completed at the outpatient visit to tabulate the dataResults: 99 (81.8% patients received chemotherapy of at least low emetogenic risk. 83 (84% patients received prophylaxis which was appropriate in 65% based on the our centre’s antiemetic regimen. This was however inappropriate in 76% of patients based on the international practice.parametersConclusions: Guidelines are not uniformly representative of all populations and modifications toguidelines based on local data are required to ensure success of such policies. There exist evidence-.practice gaps in antiemetic policies

    The therapy operating characteristic (TOC) curve, developed in the context of radiation therapy, is a plot of the probability of tumor control versus the probability of normal-tissue complications as the overall radiation dose level is varied, e.g., by varying the beam current in external-beam radiotherapy or the total injected activity in radionuclide therapy. This paper shows how TOC can be applied to chemotherapy with the administered drug dosage as the variable. The area under a TOC curve (AUTOC) can be used as a figure of merit for therapeutic efficacy, analogous to the area under an ROC curve (AUROC), which is a figure of merit for diagnostic efficacy. In radiation therapy, AUTOC can be computed for a single patient by using image data along with radiobiological models for tumor response and adverse side effects. The mathematical analogy between response of observers to images and the response of tumors to distributions of a chemotherapy drug is exploited to obtain linear discriminant functions from which AUTOC can be calculated. Methods for using mathematical models of drug delivery and tumor response with imaging data to estimate patient-specific parameters that are needed for calculation of AUTOC are outlined. The implications of this viewpoint for clinical trials are discussed.

    Shortages of essential drugs, including critical chemotherapy drugs, have become commonplace. Drug shortages cost significant time and financial resources, lead to adverse patient outcomes, delay clinical trials, and pose significant ethical challenges. Pediatric oncology is particularly susceptible to drug shortages, presenting an opportunity to examine these ethical issues and provide recommendations for preventing and alleviating shortages. We convened the Working Group on Chemotherapy Drug Shortages in Pediatric Oncology (WG) and developed consensus on the core ethical values and practical actions necessary for a coordinated response to the problem of shortages by institutions, agencies, and other stakeholders. The interdisciplinary and multiinstitutional WG included practicing pediatric hematologist-oncologists, nurses, hospital pharmacists, bioethicists, experts in emergency management and public policy, legal scholars, patient/family advocates, and leaders of relevant professional societies and organizations. The WG endorsed 2 core ethical values: maximizing the potential benefits of effective drugs and ensuring equitable access. From these, we developed 6 recommendations: (1) supporting national polices to prevent shortages, (2) optimizing use of drug supplies, (3) giving equal priority to evidence-based uses of drugs whether they occur within or outside clinical trials, (4) developing an improved clearinghouse for sharing drug shortage information, (5) exploring the sharing of drug supplies among institutions, and (6) developing proactive stakeholder engagement strategies to facilitate prevention and management of shortages. Each recommendation includes an ethical rationale, action items, and barriers that must be overcome. Implemented together, they provide a blueprint for effective and ethical management of drug shortages in pediatric oncology and beyond.

    A total of eighty patients with various malignancies seen between September 2008 and April 2009 at the University of Nigeria Teaching Hospital (UNTH) Ituku Ozalla, Enugu, Nigeria, had their absolute neutrophil counts, done at Days 0 and 12 of the first cycle of their various chemotherapeutic regimens. They were adult patients who had been diagnosed of various malignancies, consisting of Breast cancer 36 (45%), Non-Hodgkin's lymphoma 8 (10%), Hodgkin's lymphoma 13 (16.25%), Colorectal carcinoma 6 (7.5%), Multiple myeloma 7 (8.75%), Cervical carcinoma 1 (1.25%) and other malignancies 9 (11.25%), Manual counting of absolute neutrophil count was done using Turks solution and improved Neubauer counting chamber and Galen 2000 Olympus microscope. The socio demographic data of the patients were assessed from a questionnaire. There were 27 males (33.75%) and 53 females (66.25%). Their ages ranged from 18 - 80 years with a median of 45 years. The mean absolute neutrophil count of the respondents pre-and post chemotherapy was 3.7 +/- 2.1 x 10(9)/L and 2.5 +/- 1.6 x 10(9)/L respectively. There were significant differences in both the absolute neutrophil count (p=0.00) compared to the pre-chemotherapy values. Chemotherapeutic combinations containing cyclophosphamide and Adriamycin were observed to cause significant reduction in absolute neutrophil.

  8. The chemotherapy of tuberculosis: past, present and future.

    Mitchison, D; Davies, G

    2012-06-01

    The history of the development of modern chemotherapy for tuberculosis (TB), largely due to the British Medical Research Council, is first described. There is a current need to shorten the duration of treatment and to prevent and cure drug-resistant disease. These aims will only be achieved if the way in which multidrug treatment prevents resistance from emerging and the reasons for the very slow response to chemotherapy are understood. Consideration of mutation rates to resistance and the size of bacterial populations in lesions makes it very unlikely that resistance would emerge spontaneously, leaving irregularity in drug taking and inadequate dosage as the main reasons for its occurrence. Slow response to treatment seems due to the presence of persister populations whose natural history is only partly known. In the future, we need to explore the persister state in patients and in experimental murine TB, and to take it into account in the design of future mouse experiments. The activity of rifamycins and pyrazinamide is being increased by a rise in rifamycin dosage and the inhalation of pyrazinoic acid. New drugs are gradually being brought into use, initially TMC207 and the nitroimadazoles, PA824 and OPC67683. They will need to be tested in new combination regimens for drug-susceptible and multi- and extensively drug-resistant disease.

Despite the evidence supporting its use in clinical practice, only a minority of patients who undergo radical cystectomy receive preoperative chemotherapy. In addition, recommendations and methods to detect patients who would benefit the most from NAC are still unclear. The European Association of Urology (EAU guidelines panel on muscle-invasive and metastatic bladder cancer recommends the use of cisplatin-based NAC for T2-T4a, cN0 M0 bladder cancer if the patient has a performance status ≥2 and if the renal function is not impaired, but the American Urological Association, for example, does not have any guideline recommendations on this topic at all. In this review we describe the current literature supporting NAC in association with radical cystectomy in muscle-invasive urothelial carcinoma of the bladder. Evidence acquisition was made searching the Medline database for original articles published before 1st February 2014, with search terms: “neoadjuvant chemotherapy”, “radical cystectomy”, and “invasive bladder cancer”.

  10. Beyond Photodynamic Therapy: Light-Activated Cancer Chemotherapy.

    Light-activatable cytotoxic agents present a novel approach in targeted cancer therapy. The selectivity in addressing cancer cells is a crucial aspect in minimizing unwanted side effects that stem from unspecific cytotoxic activity of cancer chemotherapeutics. Photoactivated chemotherapy is based on the use of inactive prodrugs whose biological activity is significantly increased upon exposure to light. As light can be delivered with a very high spatiotemporal resolution, this technique is a promising approach to selectively activate cytotoxic drugs at their site of action and thus to improve the tolerability and safety of chemotherapy. This innovative strategy can be applied to both cytotoxic metal complexes and organic compounds. In the first case, the photoresponsive element can either be part of the ligand backbone or be the metal center itself. In the second case, the activity of a known organic, cytotoxic compound is caged with a photocleavable protecting group, providing the release of the active compound upon irradiation. Besides these approaches, also the use of photoswitchable (photopharmacological) chemotherapeutics, which allow an "on" and "off" switching of biological activity, is being developed. The aim of this review is to present the current state of photoactivated cancer therapy and to identify its challenges and opportunities.

  11. Role of chemotherapy of taeniasis in prevention of neurocysticercosis.

    2006-01-01

    Neurocysticercosis (NC) is a serious public health problem in Taenia solium endemic areas and in some immigrants and international travelers. A key intervention in preventing NC is elimination of taeniasis by chemotherapy. Currently, two safe and effective taenicides, namely niclosamide and praziquantel, are available. Both are on WHO Essential Drug list, but are often inaccessible in T. solium endemic areas. Natural remedies, still widely used in some endemic areas, are frequently carcinogenic or highly toxic and as such should be discontinued. Chemotherapeutic intervention to control T. solium taeniasis/cysticercosis, whilst theoretically feasible, has several practical obstacles. These include poor public awareness, problems with diagnosing Taenia carriers, poor availability of taenicides where needed and low priority afforded to the control of NC. These can be overcome, respectively, by effective health education, wider use of newly developed coproantigen tests, strengthening of health services infrastructure and essential drugs distribution, and increasing the priority given to prevention of NC, as a leading cause of epilepsy in T. solium endemic areas. Information is accumulating on rational approaches to population-based short-term chemotherapeutic control measures. These are: widely available modern diagnostic tools and taenicides, treatment of any case of taeniasis, confirmed or probable, focus-oriented chemotherapy, irrespective of Taenia species implicated, improved sanitation, cooperation of veterinary and medical services, linkage with programs against epilepsy and cooperation of better educated communities. Now, it remains to take an advantage of existing tools and experience.

    @@ Purpose: To observe the effects of electroacupuncture therapy on T cells and activity of NK cell in the patient of Chemotherapy. Method: Electro-acupuncture therapy was simultaneously applied during chemotherapy, T cells and activity of NK cell of patients were determined before electroacupuncture treatment (before chemotherapy) and after 4-course electro-acupuncture treatments. Results: Before chemotherapy, CD3 was low within the normal range, CD4 was much lower than the normal range, and CD8, CD4/CD8 and activity of NK cell were within the normal range. After one month of chemotherapy combined with electro-acupuncture, no decline of all the indices was found (P>0.05). Conclusion: Electro-acupuncture can really increase the immune function of patients of chemotherapy.The suppression of both immunity and hematopoiesis caused by chemotherapy is mainly characterized by declines of T cells subpopulations (CD3, CD4, CD8), activity of NK cell, WBC count and humoral immunity. Since 1996, the authors have applied electro-acupuncture therapy for 28 cases of malignant tumor in the process of chemotherapy with good results as reported in the following.

    Peripheral neuropathy caused by cytotoxic chemotherapy, especially platins and taxanes, is a widespread problem among cancer survivors that is likely to continue to expand in the future. However, little work to date has focused on understanding this challenge. The goal in this study was to determine the impact of colorectal cancer and cumulative chemotherapeutic dose on sensory function to gain mechanistic insight into the subtypes of primary afferent fibers damaged by chemotherapy. Patients with colorectal cancer underwent quantitative sensory testing before and then prior to each cycle of oxaliplatin. These data were compared with those from 47 age- and sex-matched healthy volunteers. Patients showed significant subclinical deficits in sensory function before any therapy compared with healthy volunteers, and they became more pronounced in patients who received chemotherapy. Sensory modalities that involved large Aβ myelinated fibers and unmyelinated C fibers were most affected by chemotherapy, whereas sensory modalities conveyed by thinly myelinated Aδ fibers were less sensitive to chemotherapy. Patients with baseline sensory deficits went on to develop more symptom complaints during chemotherapy than those who had no baseline deficit. Patients who were tested again 6 to 12 months after chemotherapy presented with the most numbness and pain and also the most pronounced sensory deficits. Our results illuminate a mechanistic connection between the pattern of effects on sensory function and the nerve fiber types that appear to be most vulnerable to chemotherapy-induced toxicity, with implications for how to focus future work to ameloirate risks of peripheral neuropathy.

    Full Text Available Skeletal muscle depletion (sarcopenia is closely associated with limited physical ability and high mortality. This study evaluated the prognostic significance of skeletal muscle status before and after chemotherapy in patients with unresectable colorectal cancer (CRC.We conducted a retrospective analysis of 215 consecutive patients with unresectable CRC who underwent systemic chemotherapy. Skeletal muscle cross-sectional area was measured by computed tomography. We evaluated the prognostic value of skeletal muscle mass before chemotherapy and the rate of skeletal muscle change in cross-sectional area after chemotherapy.One-hundred-eighty-two patients met our inclusion criteria. There were no significant differences in progression-free survival (PFS or overall survival (OS associated with skeletal muscle mass before chemotherapy. However, 22 patients with skeletal muscle loss (>5% after chemotherapy showed significantly shorter PFS and OS compared with those without skeletal muscle loss (PFS, log-rank p = 0.029; OS, log-rank p = 0.009. Multivariate Cox regression analysis revealed that skeletal muscle loss after chemotherapy (hazard ratio, 2.079; 95% confidence interval, 1.194-3.619; p = 0.010 was independently associated with OS.Skeletal muscle loss after chemotherapy was an independent, negative prognostic factor in unresectable CRC.

    2013-07-01

    There is a drive in the UK to revise chemotherapy provision for people living in rural communities. Using a different model of treatment delivery might impact positively upon the experience of receiving chemotherapy. In 2007 the first nurse-led mobile chemotherapy unit (MCU) in the UK was launched in the South West of England with the intention of providing treatment closer to home. The aim of the research was to explore experiences of people with cancer who received chemotherapy treatment in outpatient clinic and/or onboard the MCU using an interpretive phenomenological approach. Interviews were conducted with 20 people and data were interpreted using thematic analysis. The cancer and chemotherapy journey was described as being undertaken by the participant and their significant other. Available car parking and travelling impacted upon quality of life, as did the environment and accessibility of nurses to discuss issues with participants. The most important, distinguishing feature between receiving chemotherapy in outpatient clinic and the MCU was the amount of time spent waiting. Having treatment on the MCU was perceived to be less formal and therefore less stressful. Participants reported significant savings in time spent travelling, waiting and having treatment, expenditure on fuel and companion costs.

    Triple-negative breast cancer is the most aggressive breast cancer subtype with limited treatment options and a poor prognosis. Approximately 70% of triple-negative breast cancer patients fail to achieve a pathologic complete response (pCR) after chemotherapy due to the lack of targeted therapies for this subtype. We report here the development of a focal-plane-array Fourier transform infrared (FPA-FTIR) microspectroscopic technique combined with principal component analysis (PCA) for monitoring chemotherapy effects in triple-negative breast cancer patients. The PCA results obtained using the FPA-FTIR spectral data collected from the same patients before and after the chemotherapy revealed discriminatory features that were consistent with the pathologic and clinical responses to chemotherapy, indicating the potential of the technique as a monitoring tool for observing chemotherapy efficacy.

    Full Text Available This study aims to evaluate the efficacy and safety of goserelin combined with chemotherapy for premenopausal women with breast cancer. Literatures were extracted from databases including Excerpta Medica Database, Springer, Pubmed, China National Knowledge Infrastructure and Chinese Biological Medicine from their inception up to May 2014. The main efficacy measures were 5 years overall survival (OS, 10 years OS, 5 years disease free survival and 5 years progress free survival. Ten randomized comparison clinical trials were eligible in this study. The result showed that goserelin combined with chemotherapy group can improve the survival rate and decrease the incidence of arthralgia in postmenopausal breast cancer patients, respectively, compared to the control group. However, they can increase the occurrence of vomiting during the chemotherapy process. Compared with the simple chemotherapy, goserelin combined with chemotherapy can provide benefits for premenopausal women with breast cancer on improving the survival rate and reducing arthralgia.

  20. Neurokinin-1 receptor antagonists for chemotherapy-induced nausea and vomiting.

    2012-07-01

    Chemotherapy can be a life-prolonging treatment for many cancer patients, but it is often associated with profound nausea and vomiting that is so distressing that patients may delay or decline treatment to avoid these side effects. The discovery of several NK1 receptor antagonists is a big revolution to dealt this problem. NK1 receptor antagonists prevent both acute and delayed chemotherapy-induced nausea and vomiting (CINV). These agents act centrally at NK-1 receptors in vomiting centers within the central nervous system to block their activation by substance P released as an unwanted consequence of chemotherapy. By controlling nausea and vomiting, these agents help improve patients' daily living and their ability to complete multiple cycles of chemotherapy. They are effective for both moderately and highly emetogenic chemotherapy regimens. Their use might be associated with increased infection rates; however, additional appraisal of specific data from RCTs is needed.

However, oesophageal stricture resulting from chemotherapy alone is a rare complication, with few reports on it. We experienced a rare paediatric case of oesophageal stricture caused by chemotherapy for osteosarcoma of the left distal femur. After completion of the chemotherapy course, the patient showed dysphagia caused by the oesophageal stricture and underwent balloon dilatation for the oesophageal stricture. After balloon dilatation, he was able to ingest solid foods, and the oesophagus was normal without any strictures at the last follow-up (20 months after ballooning. Therefore, oesophageal stricture should be considered as a complication of treatment with chemotherapy alone in children with malignancies.

    Chemotherapy is one of main treatments for nasopharyngeal carcinoma (NPC) except radiation therapy. Improving and optimizing chemotherapeutic regimen are helpful to improve the therapeutic effects and reduce side effects. At present, concurrent chemoradiotherapy still is the standard treatment for advanced nasopharyngeal carcinoma. Induced chemotherapy has been shown superiority, but the effect of adjuvant chemotherapy needs further study. This paper analyzed the superior and inferior, effect and side effect of all kinds of chemotherapeutic methods or scheme including induced chemotherapy,concurrent chemotherapy, adjuvant chemotherapy and palliative chemotherapy and introduced simply the mechanism and clinical effect of new drugs of anticancer. It was hoped to offer some reference for the selection of chemotherapy for NPC.

    Full Text Available Introduction: Angiogenesis plays an important role in the biology of ovarian cancer. The clinical efficacy and side effects of bevacizumab, the vascular endothelial growth factor inhibitor, on survival and toxicity in women with this ovarian cancer, was not conclusive. We performed this systematic review and meta-analysis in order to clarify the efficacy of bevacizumab combined with chemotherapy in the treatment of ovarian cancer. Materials and Methods: We searched the electronic database of MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials and CNKI for clinical controlled trials of comparing bevacizumab combined with chemotherapy and chemotherapy alone in the treatment of ovarian cancer. The primary outcomes of eligible studies included median progression-free survival (PFS, overall survival (OS, and toxicities such as enterobrosis, hypertension, albuminuria, congestive heart failure (CHF, neutrophils, thrombosis, and bleeding. The Hazard ratio (HR and relative risk were used for the meta-analysis and were expressed with 95% confidence intervals (CIs. All the statistical analyses were carried out by  Stata 11.0 software (http://www.stata.com; Stata Corporation, College Station, TX, USA. Results: We included 5 studies with 1798 cases in the bevacizumab combined with the chemotherapy group and 1810 subjects in the chemotherapy alone group. The pooled results showed that bevacizumab + chemotherapy compared with chemotherapy alone can significant prolong the median PFS (HR, 0.64; 95% CI, 0.46-0.82; P 0.05; the toxicity analysis showed that the enterobrosis, hypertension, albuminuria, neutrophils, thrombosis, and bleeding were significantly increased in the bevacizumab + chemotherapy group compared with chemotherapy alone (Pall 0.05. Conclusion: Bevacizumab combined with chemotherapy prolonged the median PFS in patients with ovarian cancer but also increase the risk of developing enterobrosis, hypertension, albuminuria, neutrophils

    Background Correct drug selection, the key to successful chemotherapy, is one of the most difficult clinical decisions for the treatment of platinum-resistant recurrent ovarian cancer worldwide. The exact procedures for choosing drugs are undefined, currently relying on clinical trials and personal experience, which often results in disappointing outcomes. Here, we propose a new drug selection method, the "predictive molecule targeted routine chemotherapy", to choose relatively sensitive routine drugs and avoid relatively resistant routine drugs based on the specific predictive molecule expression of the individual tumor tissue.Methods From January 2004 to June 2008,26 cases of platinum-resistant recurrent ovarian cancer were prospectively recruited. Their routine chemotherapy drug choice was based on the expression of 6 predictive molecules (including p53) as determined by immunohistochemistry (the predictive molecule targeted routine chemotherapy group). A further 18 cases of platinum-resistant recurrent ovarian cancer were treated by experience and formed the control group. The response rate and the overall survival were compared between the two groups.Results The response rate to second-line chemotherapy was 28% in the control group and 77% in the predictive molecule targeted routine chemotherapy group (P=0.002). The response rate to third-line chemotherapy was 14% in the control group and 33% in the predictive molecule targeted routine chemotherapy group (P=0.268). The median overall survival of the predictive molecule targeted routine chemotherapy group (88 weeks) was significantly longer than the median overall survival of the control group (56 weeks) (P=0.0315).Conclusion The predictive molecule targeted routine chemotherapy is a new effective protocol for choosing drugs when treating platinum-resistant recurrent ovarian cancer.

    There is wide variation in the proportion of newly diagnosed cancer patients who receive chemotherapy, indicating the need for a benchmark rate of chemotherapy utilisation. This study describes an evidence-based model that estimates the proportion of new cancer patients in whom chemotherapy is indicated at least once (defined as the optimal chemotherapy utilisation rate). The optimal chemotherapy utilisation rate can act as a benchmark for measuring and improving the quality of care. Models of optimal chemotherapy utilisation were constructed for each cancer site based on indications for chemotherapy identified from evidence-based treatment guidelines. Data on the proportion of patient- and tumour-related attributes for which chemotherapy was indicated were obtained, using population-based data where possible. Treatment indications and epidemiological data were merged to calculate the optimal chemotherapy utilisation rate. Monte Carlo simulations and sensitivity analyses were used to assess the effect of controversial chemotherapy indications and variations in epidemiological data on our model. Chemotherapy is indicated at least once in 49.1% (95% confidence interval 48.8-49.6%) of all new cancer patients in Australia. The optimal chemotherapy utilisation rates for individual tumour sites ranged from a low of 13% in thyroid cancers to a high of 94% in myeloma. The optimal chemotherapy utilisation rate can serve as a benchmark for planning chemotherapy services on a population basis. The model can be used to evaluate service delivery by comparing the benchmark rate with patterns of care data. The overall estimate for other countries can be obtained by substituting the relevant distribution of cancer types. It can also be used to predict future chemotherapy workload and can be easily modified to take into account future changes in cancer incidence, presentation stage or chemotherapy indications.

    Eisen, Martin

    1979-01-01

    The purpose of this book is to show how mathematics can be applied to improve cancer chemotherapy. Unfortunately, most drugs used in treating cancer kill both normal and abnormal cells. However, more cancer cells than normal cells can be destroyed by the drug because tumor cells usually exhibit different growth kinetics than normal cells. To capitalize on this last fact, cell kinetics must be studied by formulating mathematical models of normal and abnormal cell growth. These models allow the therapeutic and harmful effects of cancer drugs to be simulated quantitatively. The combined cell and drug models can be used to study the effects of different methods of administering drugs. The least harmful method of drug administration, according to a given criterion, can be found by applying optimal control theory. The prerequisites for reading this book are an elementary knowledge of ordinary differential equations, probability, statistics, and linear algebra. In order to make this book self-contained, a chapter on...

    2016-10-01

    Mucositis is a common side effect of cancer therapies that causes painful, erythematous lesions to develop in the gastrointestinal tract. These lesions can lead to malnutrition, increased risk for serious infection, prolonged hospital stays, and reduced quality of life. Oral cryotherapy, or the use of ice chips to cool the mucous membranes during bolus chemotherapy infusions (e.g., 5-fluorouracil [Adrucil®] and melphalan [Alkeran®]), is the most readily accessible and cost-effective intervention available. Although many factors may contribute to the development of mucositis during cancer treatment, studies have found a reduction in the incidence and the severity of mucositis with the use of oral cryotherapy.


  13. A Novel Drug Delivery System for Osteosarcoma Chemotherapy

    Institute of Scientific and Technical Information of China (English)

    2005-01-01

    A thermo-responsive chitosan hydrogel system (TRCHS) was prepared by chitosan ( CS ) andβ- glycerophosphate ( β- GP ) to deliver Adriamycin (ADM) locally for curing osteosarcoma . Release property was investigated by release experiments in vitro and results show that it can be applied to local drug release because it is able to release drug at high concentration for 17 days. The treatment effect was studied by injecting intratumorally to osteosarcoma tumors ( CRL- 1427) implanted subcutaneously on Specific Pathogen-free (SPF) mice. The statistical analytical results show that TRCHS delivering ADM is more efficacious than saline intratumoral injection,which loads the same quantity of ADM , but is less poisonous. Based on the analysis above, this novel biodegradable polymer implant is an effective and safe vehicle for sustained local delivery of ADM, and is supposed to be applied in neoadjuvant chemotherapy for osteosarcoma.

  15. Combining chemotherapy and targeted therapies in metastatic colorectal cancer

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    Colorectal cancer remains one of the major causes of cancer death worldwide. During the past years, the development of new effective treatment options has led to a considerable improvement in the outcome of this disease. The advent of agents such as capecitabine, irinotecan, oxaliplatin, cetuximab and bevacizumab has translated into median survival times in the range of 2 years. Intense efforts have focused on identifying novel agents targeting specific growth factor receptors, critical signal transduction pathways or mediators of angiogenesis. In addition, several clinical trials have suggested that some of these molecularly targeted drugs can be safely and effectively used in combination with conventional chemotherapy. In this article we review various treatment options combining cytotoxic and targeted therapies currently available for patients with metastatic colorectal cancer.

    Marcial eRodríguez

    2013-08-01

    Full Text Available Anticipatory Nausea (AN is a severe side effect of chemotherapy that can lead cancer patients to discontinue their treatment. This kind of nausea is usually elicited by the re-exposure of the patients to the clinical context they need to attend to be treated. There has been considerable agreement that AN represents a paradigmatic example of Pavlovian conditioning, and within this framework, several behavioral interventions have been proposed in order to prevent this psychopathology. However, some studies have questioned the validity of the Pavlovian approach, suggesting that CS-US associations are neither necessary nor sufficient for AN to occur. The data and the alternative theories behind such criticisms are discussed. Additionally, it is suggested that animal models of AN could be enriched by taking into account rats’ individual differences.

    The authors report the results of a prospective, multi-centre trial involving 87 patients with previously untreated myeloma who were treated by combination chemotherapy consisting of melphalan, cyclophosphamide, CCNU, prednisone and vincristine. 83.1% of patients had a high tumour mass (stage III on Durie and Salmon's classification). The response to treatment could be evaluated in 76 patients and 70% were found to respond. The median actuarial survival of the whole population is 30 months. The survival is significantly longer (p less than 0.001) in responders (median 40 months) than in non-responders (median: 17 months); the survival is significantly shorter (p less than 0.01) in subjects with renal failure (median: 10 months) than in subjects without renal failure (median: 36 months). This treatment is sufficiently well tolerated to be administered on an outpatient basis. One case of acute monoblastic leukaemia was observed. These results are similar to those reported in the literature.

    Full Text Available Neoadjuvant chemotherapy (NAC is widely used in locally advanced breast cancer (BC treatment. The role of postmastectomy radiotherapy (PMRT after NAC is strongly debated. The aim of our analysis was to identify major prognostic factors in a single-center series, with emphasis on PMRT. From 1997 to 2011, 170 patients were treated with NAC and mastectomy at our center; 98 cases (57.6% underwent PMRT and 72 cases (42.4% did not receive radiation. At a median follow-up period of 7.7 years (range 2–16 for the whole cohort, median time to locoregional recurrence (LRR was 3.3 years (range 0.7–12.4. The 5-year and 10-year actuarial LRR rate were 14.5% and 15.9%, respectively. At the multivariate analysis the factors that significantly correlated with survival outcome were ≥4 positive nodes (HR 5.0, 1.51–16.52; P=0.035, extracapsular extension (HR 2.18, 1.37–3.46; P=0.009, and estrogen receptor positive disease (HR 0.57, 0.36–0.90; P=0.003. Concerning LRR according to use of radiation, PMRT reduced LRR for patient with clinical T3 staged disease (P=0.015. Our experience confirmed the impact of pathological nodal involvement on survival outcome. PMRT was found to improve local control in patients presenting with clinical T3 tumors, regardless of the response to chemotherapy.

    There are marked individual differences in conditioned nausea after cancer chemotherapy. To examine if part of this variation is associated with individual differences in autonomic nervous system conditionability, the present study addressed whether patients with conditioned nausea acquired conditioned heart rate and electrodermal responses at a different rate than patients without conditioned nausea. Of 28 relapse-free patients who had completed cisplatinum treatment for testicular cancer between 1981 and 1986, 10 reported persistent conditioned nausea, 8 extinguished conditioned nausea and 10 no conditioned nausea. These three groups were subjected to a differential conditioning paradigm with 8 sec pictorial stimuli (circles and triangles) serving as conditioned stimuli for an unconditioned electric shock while heart rate and electrodermal activity was monitored. There were 4 habituation, 8 acquisition and 8 extinction trials with each of the two cues. Analyses of variance using nausea status as the independent variable and physiological responses as the dependent lended some support to the notion that conditioned heart rate deceleration developed in response to the reinforced compared to the nonreinforced cue during acquisition in the two groups with persistent or extinguished conditioned nausea but not in the group with no conditioned nausea. In addition, patients that displayed good, as compared to poor heart rate conditionability during acquisition, were more likely to have persistent conditioned nausea, whereas those who showed poor heart rate conditioning mostly were those without conditioned nausea. Electrodermal variables revealed no systematic differences between groups. This tentatively supports that individual differences in parasympathetic but not sympathetic nervous system conditionability may be associated with individual differences in conditioned nausea resulting from cancer chemotherapy.

  20. Chemotherapy as language: sound symbolism in cancer medication names.

    The concept of sound symbolism proposes that even the tiniest sounds comprising a word may suggest the qualities of the object which that word represents. Cancer-related medication names, which are likely to be charged with emotional meaning for patients, might be expected to contain such sound-symbolic associations. We analyzed the sounds in the names of 60 frequently-used cancer-related medications, focusing on the medications' trade names as well as the names (trade or generic) commonly used in the clinic. We assessed the frequency of common voiced consonants (/b/, /d/, /g/, /v/, /z/; thought to be associated with slowness and heaviness) and voiceless consonants (/p/, /t/, /k/, /f/, /s/; thought to be associated with fastness and lightness), and compared them to what would be expected in standard American English using a reference dataset. A Fisher's exact test for independence showed the chemotherapy consonantal frequencies to be significantly different from standard English (p=0.009 for trade; p<0.001 for "common usage"). For the trade names, the majority of the voiceless consonants were significantly increased compared to standard English; this effect was more pronounced with the "common usage" names (for the group, O/E=1.62; 95% CI [1.37, 1.89]). Hormonal and targeted therapy trade names showed the greatest frequency of voiceless consonants (for the group, O/E=1.76; 95% CI [1.20, 2.49]). Our results suggest that taken together, the names of chemotherapy medications contain an increased frequency of certain sounds associated with lightness, smallness and fastness. This finding raises important questions about the possible role of the names of medications in the experiences of cancer patients and providers.

    Bacterial infection is a common clinical problem. The emergence of antibiotic resistant bacteria posts a severe challenge to medical practice worldwide. Photodynamic antimicrobial chemotherapy (PACT) uses laser light at specific wavelength to activate oxygen molecule in the human tissue into reactive oxygen species as antimicrobial agent. This activation of oxygen by laser light is mediated through a photosensitizer. Two key properties for potent photosensitizer are its absorbance of light in the infrared region (630–700 nm), which promotes tissue penetration depth, and the selective accumulation on bacteria instead of human tissue. We herein report a zinc phthalocyanine derivative, pentalysine β-carbonylphthalocyanine zinc (ZnPc-(Lys){sub 5}) and its antimicrobial effects in vitro and in an animal infection model. This photosensitizer has strong capability to kill bacteria at 670 nm. Chemically, it is a water-soluble and cationic photosensitizer carrying positive charge under physiological pH, and can specifically target to bacteria which usually bears negative charges on its surface. Compared with anionic ZnPc counterparts, ZnPc-(Lys){sub 5} shows a higher phototoxicity toward bacteria. PACT studies of ZnPc-(Lys){sub 5} in experimental infection animal model showed a significant bacteria inhibition compared to controls, and high selectivity of ZnPc-(Lys){sub 5} toward bacteria. These findings suggest ZnPc-(Lys){sub 5} is a promising antimicrobial photosensitizer for the treatment of infectious diseases. - Highlights: • Photodynamic antimicrobial chemotherapy (PACT) with water-soluble zinc phthalocyanine derivative offers a promising measure to deal with antibiotic resistance of bacteria. • The use of portable LED light sources that are battery-powered and with low cost may make possible the deployment of systems that can be used for wound decontamination. • ZnPc-(Lys){sub 5} is a potent photosensitizer for treatment of infectious diseases.

    Full Text Available BACKGROUND: Magnetic nanoparticles (NPs loaded with antitumor drugs in combination with an external magnetic field (EMF-guided delivery can improve the efficacy of treatment and may decrease serious side effects. The purpose of this study was 1 to investigate application of PEG modified GMNPs (PGMNPs as a drug carrier of the chemotherapy compound doxorubicin (DOX in vitro; 2 to evaluate the therapeutic efficiency of DOX-conjugated PGMNPs (DOX-PGMNPs using an EMF-guided delivery in vivo. METHODS: First, DOX-PGMNPs were synthesized and the cytotoxicity of DOX-PGMNPs was assessed in vitro. Second, upon intravenous administration of DOX-PMGPNs to H22 hepatoma cell tumor-bearing mice, the DOX biodistribution in different organs (tissues was measured. The antitumor activity was evaluated using different treatment strategies such as DOX-PMGPNs or DOX-PMGPNs with an EMF-guided delivery (DOX-PGMNPs-M. RESULTS: The relative tumor volumes in DOX-PGMNPs-M, DOX-PGMNPs, and DOX groups were 5.46±1.48, 9.22±1.51, and 14.8±1.64, respectively (each p<0.05, following treatment for 33 days. The life span of tumor-bearing mice treated with DOX-PGMNPs-M, DOX-PGMNPs, and DOX were 74.8±9.95, 66.1±13.5, and 31.3±3.31 days, respectively (each p<0.05. CONCLUSION: This simple and adaptive nanoparticle design may accommodate chemotherapy for drug delivery optimization and in vivo drug-target definition in system biology profiling, increasing the margin of safety in treatment of cancers in the near future.

    Abstract The present observational cohort study was designed to elucidate the efficacy and safety profile of bevacizumab or cetuximab with chemotherapy as the first-line treatment in Chinese patients with metastatic colorectal cancer (mCRC). Clinical data were collected from a single-center registry study where mCRC patients received first-line fluoropyrimidine-based chemotherapy combined with either bevacizumab (188 patients with KRAS wild-type or mutated tumors) or cetuximab (101 patients with KRAS wild-type tumors) between January 2009 and December 2013. The Kaplan–Meier method was used for survival analysis. Cox proportional hazards model was used for estimating the prognostic and predictive values of clinicopathological characteristics. No statistically significant difference was observed between the bevacizumab and cetuximab groups in terms of median progression-free survival (PFS) (10.6 vs 8.7 months, P = 0.317), median overall survival (OS) (27.7 vs 28.3 months, P = 0.525), or overall response rate (43.1% vs 53.5%, P = 0.108). For the subset of patients with peritoneal dissemination, bevacizumab-based triplet appears to be superior to cetuximab-based triplet as measured by PFS (9.6 vs 6.1 months) and OS (26.3 vs 12.7 months), but not for patients without peritoneal dissemination (PFS, 10.6 vs 9.1 months; OS, 27.9 vs 30.7 months) (all unadjusted and adjusted interaction P < 0.05). Our study suggests that bevacizumab- or cetuximab-based regimens have similar effectiveness as first-line treatment of mCRC in Chinese population. Patients with peritoneal dissemination were likely to gain more benefit from bevacizumab than cetuximab treatment. Future prospective studies are required to further confirm these results.

    2015-01-01

    In this case study, the process of nutritional diagnosis and intervention conducted at a hospital on a malnourished patient who underwent treatment for a chronic illness (chemotherapy for cancer treatment) was recorded. The patient received his first round of chemotherapy for colorectal cancer, and then a second round after the cancer metastasized to the liver. The patient was malnourished and had experienced weight loss (17% loss in the most recent 3 months) due to side effects of chemotherapy including stomatitis, nausea, and vomiting. Nutritional diagnosis and intervention via the nutrition care process were implemented through two screening rounds, and the quantity of oral intake increased from 28% to 62% of the recommended daily intake. The patient required continuous monitoring and outpatient care after hospital discharge. It is speculated that if a more active patient education and dietary regimen with respect to chemotherapy side effects had been offered after the patient's first chemotherapy cycle, it might have been possible to treat ingestion problems due to stomatitis during the second cycle of chemotherapy and prevent the weight loss. Henceforth, patients receiving chemotherapy should be educated about nutrition management methods and monitored continuously to prevent malnutrition.

    Objective: Applying mobile base systems in cancer care especially in chemotherapy management have remarkable growing in recent decades. Because chemotherapy side effects have significant influences on patient’s lives, therefore it is necessary to take ways to control them. This research has studied some experiences of using mobile phone based systems to home-based monitor of chemotherapy side effects in cancer. Methods: In this literature review study, search was conducted with keywords like cancer, chemotherapy, mobile phone, information technology, side effects and self managing, in Science Direct, Google Scholar and Pub Med databases since 2005. Results: Today, because of the growing trend of the cancer, we need methods and innovations such as information technology to manage and control it. Mobile phone based systems are the solutions that help to provide quick access to monitor chemotherapy side effects for cancer patients at home. Investigated studies demonstrate that using of mobile phones in chemotherapy management have positive results and led to patients and clinicians satisfactions. Conclusion: This study shows that the mobile phone system for home-based monitoring chemotherapy side effects works well. In result, knowledge of cancer self-management and the rate of patient’s effective participation in care process improved. PMID:27482134

    Full Text Available OBJECTIVE: We examined our database of patients undergoing radical cystectomy (RC with orthotopic neobladder (NB to determine whether adjuvant chemotherapy in this group is safe. MATERIALS AND METHODS: We performed a retrospective analysis of patients who underwent radical cystectomy and urinary diversion between 1992 and 2004. Relevant clinical and therapeutic data were entered into a database. High-risk bladder cancer patients who underwent NB were identified. They were stratified into 2 groups, those who received adjuvant chemotherapy and those who did not. The incidence of complications between the 2 groups was analyzed and compared. RESULTS: Over the 12-year period, 136 patients underwent RC and NB construction for bladder cancer. Of these, 83 patients were at high risk for recurrence. Nineteen patients received adjuvant chemotherapy and 64 did not. The complication rate in the adjuvant chemotherapy group was 53% and it was 23% in those who did not receive chemotherapy. There were no perioperative or treatment related death. There were 2 patients with grade 4 toxicity in the adjuvant chemotherapy group. There was a statistical difference between these two groups with regard to the incidence of complications. However, none of these complications was life-threatening, required only conservative treatment and caused no long-term disability. CONCLUSIONS: Adjuvant chemotherapy is a safe treatment for patients undergoing RC and NB substitution. Hence, the option of orthotopic NB should not be denied in selected bladder cancer patients with high risk for recurrent disease.

    Full Text Available BACKGROUND: Molecular predictors for the effectiveness of adjuvant chemotherapy in colorectal cancer are of considerable clinical interest. To this aim, we analyzed the serine threonine receptor-associated protein (STRAP, an inhibitor of TGF-βsignaling, with regard to prognosis and prediction of adjuvant 5-FU chemotherapy benefit. i The gene copy status of STRAP was determined using quantitative realtime polymerase chain reaction in 166 colorectal tumor biopsies, which had been collected from a randomized multicenter trial of 5-fluorouracil (5-FU/mitomycin C (MMC adjuvant chemotherapy of the Swiss Group for Clinical Cancer Research (SAKK. RESULTS: Amplification of STRAP was found in 22.8% of the tumors. When left without adjuvant chemotherapy, patients bearing tumors with a STRAP amplification had a significantly better prognosis (hazard ratio for death: 0.26; P = .004. Interestingly, these patients, when receiving adjuvant treatment, had a worse survival (hazard ratio for death: 3.48; P = .019 than without chemotherapy, whereas patients carrying tumors with diploidy or deletion of STRAP benefited from the treatment (hazard ratio for death: 0.44; P = .052. This suggests the amplification of STRAP as a strong predictor of an unfavorable effect of 5-FU-based adjuvant chemotherapy. CONCLUSION: If confirmed, the STRAP gene copy status might provide a parameter to decide about the use of 5-FU-based adjuvant chemotherapy.

    Intrahepatic cholangiocarcinoma (ICC) is a relatively rare and highly fatal neoplasm that arises from the biliary epithelium. Prognosis is generally poor and survival is limited to a few months. Here we present a case of advanced ICC successfully treated by chemosensitivity test-guided systemic chemotherapy combining S-1 and cisplatin (CDDP). A 65-year-old woman with a liver tumor was referred to our hospital on November 21, 2007. Abdominal ultrasonography and computed tomography (CT) showed low-density masses of 50 and 15 mm in diameter, respectively in segment Ⅷ of the liver and in the enlarged lymph node in the para-aorta. Ultrasonography-guided fine needle biopsy diagnosed the tumors as ICC. Since the patient was inoperable for lymph node metastasis, she underwent systemic chemotherapy with gemcitabine. Six months after initiation of chemotherapy, CT revealed ICC progression in the liver and pleural dissemination with pleural effusion. The patient was admitted to our hospital for anticancer drug sensitivity testing on June 9, 2008. Based on the sensitivity test results, we elected to administer systemic chemotherapy combining S-1 and CDDP. Two months into the second chemotherapy treatment, CT revealed a reduction of the tumors in the liver and lymph node and a decrease in pleural effusion.After eight cycles of the second chemotherapy, 17 mo after ICC diagnosis, she is alive and well with no sign of recurrence. We conclude that chemosensitivity testing may effectively determine the appropriate chemotherapy regimen for advanced ICC.

    Full Text Available Abstract Background Surgery is often advocated in patients with resectable pulmonary metastases from colorectal cancer (CRC. Our study aims to evaluate peri-operative chemotherapy in patients with metastastic CRC undergoing pulmonary metastasectomy. Methods Patients treated for CRC who underwent pulmonary metastasectomy by a single surgeon were identified. Outcome measures included survival, peri-operative complications, radiological and histological evidence of chemotherapy-induced lung toxicities. Results Between 1997 and 2009, 51 eligible patients were identified undergoing a total of 72 pulmonary resections. Thirty-eight patients received peri-operative chemotherapy, of whom 9 received an additional biological agent. Five-year overall survival rate was 72% in the whole cohort - 74% and 68% in those who received peri-operative chemotherapy (CS and those who underwent surgery alone (S respectively. Five-year relapse free survival rate was 31% in the whole cohort - 38% and ≤18% in CS and S groups respectively. Only 8% had disease progression during neoadjuvant chemotherapy. There were no post-operative deaths. Surgical complications occurred in only 4% of patients who received pre-operative chemotherapy. There was neither radiological nor histological evidence of lung toxicity in resected surgical specimens. Conclusions Peri-operative chemotherapy can be safely delivered to CRC patients undergoing pulmonary metastasectomy. Survival in this selected group of patients was favourable.

    Full Text Available Background and objective With development of modern medicine, eliminating patients’ pain and mental disorder and improving the quality of life has become an important problem in patients with cancer. The aim of this study is to observe the impact of chemotherapy on quality of life and influencing factor of quality of life among lung cancer patients. Methods Sixty-one lung cancer patients were assessed with clinical outcomes and the EORTC QLQ-C30 questionnaires before chemotherapy, one week after 2 cycles of chemotherapy, one week after 4 cycles of chemotherapy. Results After 2 cycles of chemotherapy, effective rate was 40.0%. Social function decreased. Nause and vomiting, insomnia and appetite loss deteriorated (P0.05. Grouped according to the plasma albumin level, the difference wasn’t statistically significant (P>0.05. In hypoproteinemia group, symptoms and economic difficulties score was higher; High protein group, function and general health scores was higher. Conclusion After the chemotherapy, patients’ the lesion of cancer became smaller and clinical symptoms relieved, but some patients, fatigue, appetite loss, nausea and vomiting symptom deteriorated, emotion became bad. Quality of life of lung cancer patients decrease. We should pay more attention to the adverse reactions of chemotherapy and cope with them, give positive psychological intervention and improve patients, nutrition to improve the quality of life.

    Purpose: To evaluate the tolerability and toxicity of administering vaginal brachytherapy (VB) concurrently during chemotherapy compared with the sequential approach for patients with endometrial cancer. Methods and Materials: A retrospective analysis of 372 surgically staged patients with endometrial cancer American Joint Committee on Cancer 2009 stages I to IV treated with adjuvant postoperative radiation therapy (RT) at our institution from 2001 to 2012 was conducted. All patients received VB + external beam RT (EBRT) + 6 cycles of adjuvant carboplatin- and paclitaxel-based chemotherapy. The VB mean dose was 15.08 Gy (range, 15-20 Gy), with 3 to 4 weekly applications, and the EBRT mean dose was 45 Gy delivered with 3-dimensional or intensity modulated RT techniques. Hematologic, gastrointestinal (GI), and genitourinary (GU) toxicities were assessed by Common Toxicity Criteria (CTC) and compared between sequential and concurrent chemotherapy and VB schedules. Results: Among patients who received RT and adjuvant chemotherapy, 180 of 372 patients (48%) received RT sandwiched between cycles 3 and 4 of chemotherapy. A separate group of 192 patients (52%) were treated with VB during the first 3 cycles of chemotherapy, with a weekly application on nonchemotherapy days, and received the EBRT portion in a sandwiched fashion. Patients treated with VB during chemotherapy had a decreased overall treatment time by 4 weeks (P<.001; 95% confidence interval: 3.99-4.02) and sustained no difference in CTC-graded acute hematologic, GI, or GU toxicities in comparison with the patients treated with VB and chemotherapy in a sequential manner (P>.05). CTC grade 3 or 4 hematologic, GI, and GU toxicities were zero. Conclusions: VB during chemotherapy is well tolerated, decreases overall treatment time, and does not render more toxicity than the sequential regimen.

    As it remains uncertain whether patients with advanced gastric cancer who progress after first-line chemotherapy should receive second-line chemotherapy, we attempted to identify the optimal indications for second-line chemotherapy. In this retrospective study, 101 patients were included in univariate and multivariate analyses to identify clinicopathological variables independently associated with longer survival postprogression (SPP), defined as the time from recognition of disease progression on first-line chemotherapy to death from any cause or last follow-up. The median SPP was 340 days. On multivariate analysis, performance status 2 [hazard ratio (HR), 14.234; 95% confidence interval (CI), 2.766-73.258], serum albumin level less than 3.5 g/dl (HR, 2.088; 95% CI, 1.047-4.060) at initiation of second-line chemotherapy, and time to progression less than 170 days on first-line chemotherapy (HR, 2.497; 95% CI, 1.227-5.083) were identified as independent prognostic factors associated with shorter SPP. The median SPP was 496, 375, and 232 days in patients with 0, 1, and 2 of these 3 negative prognostic factors, respectively (P=0.0002). The present study suggests that second-line chemotherapy would not be beneficial in patients with two or more of the following three negative prognostic factors: performance status 2, serum albumin less than 3.5 g/dl at initiation of second-line chemotherapy and time to progression less than 170 days on first-line chemotherapy.

    Chemotherapy for advanced colitis-associated colorectal cancer (CAC) has been insufficiently evaluated. The goal of this study was to clarify the efficacy and safety of chemotherapy for CAC in Japan. CAC patients who were treated with chemotherapy between 2005 and 2015 were retrospectively examined. Twenty-nine patients (median age, 48 years; 23 men) were assessed. Eighteen patients had ulcerative colitis, and 11 had Crohn's disease. Three ulcerative colitis and four Crohn's disease patients were in the active disease phase. Primary tumors were located in the rectum/anus (n=16), the left colon (n=9), or the right colon (n=4). Palliative or adjuvant chemotherapy was performed in 13 and 16 patients, respectively. First-line palliative chemotherapy regimens were as follows: fluorouracil, leucovorin, and oxaliplatin (FOLFOX; n=6), FOLFOX+bevacizumab (n=3), and others (n=4). Adjuvant chemotherapy regimens were S-1 (n=7), oxaliplatin-based (n=4) and others (n=5). In palliative chemotherapy, the objective response rate was 15%, and the median progression-free survival and overall survival were 182 and 315 days, respectively. In adjuvant chemotherapy, the 5-year relapse-free survival rate was 78%. Grade 3/4 adverse events (AEs) were observed in 16 patients (55%). Active and remission inflammatory bowel disease patients suffered grade 3/4 nonhematological AEs at an incidence of 71 and 23%, respectively (Pchemotherapy for CAC exhibited sufficient efficacy, whereas modest efficacy was shown for palliative chemotherapy for CAC. AEs, particularly nonhematological AEs, were closely associated with disease activity of colitis.

    The effect of chemotherapy on peritoneal carcinomatosis(PC) of gastric cancer remains unclear.Recently,the intraperitoneal(IP) administration of taxanes [e.g.,paclitaxel(PTX) and docetaxel(DOC)] during the perioperative period has shown promising results.Herein,we summarized the rationale and methodology for using IP chemotherapy with taxanes and reviewed the clinical results.IP administered taxanes remain in the IP space at an extremely high concentration for 48-72 h.The drug directly infiltrates peritoneal metastatic nodules from the surface and then produces antitumor effects,making it ideal for IP chemotherapy.There are two types of perioperative IP chemotherapy with taxanes: neoadjuvant intraperitoneal and systemic chemotherapy and sequential perioperative intraperitoneal chemotherapy(SPIC).In SPIC,patients receive neoadjuvant IP chemotherapy and the same regimen of IP chemotherapy after cytoreductive surgery(CRS) until disease progression.Usually,a taxane dissolved in 500-1000 m L of saline at ordinary temperature is administered through an IP access port on an outpatient basis.According to phase Ⅰ?studies,the recommended doses(RD) are as follows: IP DOC,45-60 mg/m2; IP PTX [without intravenous(IV) PTX],80 mg/m2; and IP PTX(with IV PTX),20 mg/m2.Phase Ⅱ studies have reported a median survival time of 14.4-24.6 mo with a 1-year overall survival of 67%-78%.A phase Ⅲ study comparing S-1 in combination with IP and IV PTX to S-1 with IV cisplatin started in 2011.The prognosis of patients who underwent CRS was better than that of those who did not; however,this was partly due to selection bias.Although several phase Ⅱ studies have shown promising results,a randomized controlled study is needed to validate the effectiveness of IP chemotherapy with taxanes for PC of gastric cancer.

    2007-01-01

    Objective To evaluate the anti-tumor effect and toxicity of gemcitabine combined with platinum chemotherapy on recurrent epithelial ovarian cancer.Methods Phase Ⅱ study of gemcitabine combined with platinum chemotherapy was carried out in 22 patients with recurrent epithelial ovarian cancer. Median age of patients was 50. 5 years old. Seven patients were platinum-sensitive and 15 patients were platinum-resistant or -refractor. All patients received gemcitabine combined with carboplatin or oxaliplatin chemotherapy. Patients' response rate (RR) and toxicity of gemcitabine combined with platinum chemotherapy were evaluated.Results A total of 98 gemcitabine-based chemotherapy cycles were performed. Total RR was 36.4%, RR of platinum-sensitive patients was 4/7 and platinum-resistant and -refractory patients was 4/15. The estimated median survival time was 10. 0 months (95% CI: 7.0-13.0) after initiation of gemcitabine combined with platinum chemotherapy.There was no significant difference in survival time between platinum-resistant/refractory group and platinum-sensitive group (P = 0. 061 ). Side effects of gemcitabine combined with platinum chemotherapy were observed in 81.8 % of patients. Grade Ⅱ/Ⅲ anemia (54.5%) and grade Ⅲ/Ⅳ neutropenia (54.5%) were most common toxicities. Ten (45.5%) patients had to delay their chemotherapy cycles or reduce the dose of chemotherapeutic drugs because of the severe side effects. Fourteen (63.6%) patients received granulocyte colony-stimulating factor to relieve neutropenia,and 8 (36. 4% ) patients received component blood transfusion to treat anemia or thrombocytopenia. There was no treatment-associated death.Conclusion Gemcitabine combined with platinum chemotherapy appears to be an effective and well-tolerant treatment for recurrent epithelial ovarian cancer, including platinum-resistant or -refractory diseases.

    The standard treatment in children with average-risk medulloblastoma (MB) is reduced-dose radiotherapy (RT) followed by chemotherapy. However, in adults, there is no agreement on the use of adjuvant chemotherapy. We performed a retrospective analysis of adult MB patients with average-risk disease, defined as no postsurgical residual (or ≤1.5 cm(2)) and no metastatic disease (M0). Main inclusion criteria were: age >16 years, post-surgical treatment with craniospinal irradiation with or without adjuvant chemotherapy (cisplatin and etoposide ± cyclophosphamide). From 1988 to 2012 were accrued 43 average-risk MB patients treated with surgery and adjuvant RT. Fifteen (34.9 %) patients received also chemotherapy: 7 before RT, 5 after RT, and 3 before and after RT. Reasons to administer chemotherapy were presence of residual disease (even if ≤1.5 cm) and delay in RT. After a median follow up time of 10 years (range: 8-13), median survival was 18 years (95 % CI 9-28) in patients who receive RT alone, and was not reached in patients treated with RT plus chemotherapy. The survival rates at 5, 10 and 15 years were 100 %, 78.6 % (95 % CI 60.0-97.2 %) and 60.2 % (95 % CI 36.9-83.5 %), in patients treated with RT alone, and 100, 100 and 100 %, in patients treated with RT plus chemotherapy (p = 0.079). Our findings suggest a role for adjuvant chemotherapy in the treatment of average-risk MB adult patients. Further improvements might drive to add chemotherapy in average-risk setting with less favourable biological signatures (i.e., non-WNT group).

    Full Text Available Basal cell carcinoma (BCC is the most common cancer among humans, and the standard treatment is surgery. Other modalities are reserved as a second line of treatment. Topical chemotherapy may be used in primary BCC. Systemic chemotherapy has no role in the primary treatment of BCC, although it may be efficacious in metastatic cases. We report the case of a patient with persistent recurrent BCC following multiple surgeries and radiotherapy, who achieved a dramatic response with a cisplatinand 5-flourouracil chemotherapy regimen.

    2011-07-01

    Chemotherapy-induced cardiotoxicity has become a significant public health issue. Left ventricular ejection fraction is routinely used to monitor cardiotoxicity but fails to detect subtle alterations in cardiac function. Improvements in the measurement of left ventricular ejection fraction, physical or pharmacologic stressors, and novel cardiac functional indices may be useful in the detection of cardiotoxicity. The improvements in the detection and therapy of cancer have led to the emergence of chemotherapy-induced cardiotoxicity. New echocardiographic techniques may be useful in the detection of patients undergoing chemotherapy treatments who could benefit from alternative cancer treatments, therefore decreasing the incidence of cardiotoxicity.

    2017-01-01

    Simple Summary Cancer is as common amongst pets as it in humans. Chemotherapy can be integrated into treatment regimes for terminally ill pets to attempt to shrink tumours to extend life expectancy, but it does not cure cancer and it can have negative side effects including vomiting, depression and behavioral changes. To date, little research has been undertaken to explore owners’ decisions whether or not to treat their animals with chemotherapy. Seventy-eight dog and cat owners completed an online questionnaire to determine if they would opt for chemotherapy if their pet was diagnosed with cancer, and asked how they thought their pet’s quality of life would be affected. Fifty-eight percent of respondents would not use chemotherapy largely due to their previous experience of it. Seventy-two percent over estimated pet survival time post chemotherapy, with most people believing it would lead to remission or a cure. Owners expected their pets to be less active, sleep more and play less, reducing their quality of life. Common side effects associated with chemotherapy were not rated as acceptable. The results suggest pet owners would benefit from an increased understanding of the positive and negative impacts of chemotherapy when initially discussing treatment options with the veterinary team. Abstract Chemotherapy is a commonly integrated treatment option within human and animal oncology regimes. Limited research has investigated pet owners’ treatment decision-making in animals diagnosed with malignant neoplasia. Dog and cat owners were asked to complete an online questionnaire to elucidate factors which are key to the decision making process. Seventy-eight respondents completed the questionnaire in full. Fifty-eight percent of pet owners would not elect to treat pets with chemotherapy due to the negative impact of the associated side effects. Seventy-two percent of respondents over estimated pet survival time post chemotherapy, indicating a general perception

  4. Chemotherapy-induced nausea and vomiting. Easing patients' fear and discomfort with effective antiemetic regimens.

    Bilgrami, S; Fallon, B G

    1993-10-01

    Patients receiving chemotherapy should be given optimal antiemetic therapy to maximize their comfort initially and to prevent development of delayed and anticipatory nausea and vomiting. Understanding the mechanisms of chemotherapy-induced nausea and vomiting allows the healthcare team to design drug regimens capable of avoiding these side effects. Prevention is important, because side effects can be debilitating and sometimes dose-limiting, and up to 10% of patients refuse chemotherapy altogether to avoid them. In general, combination antiemetic therapy is preferred over single-agent therapy for chemotherapeutic regimens that produce moderate to severe adverse effects.

    The treatment of malignancies in HIV patients is challenged by the issue of drug-drug interactions between antiretroviral therapy and antineoplastic agents. While protease inhibitors have been shown to increase the incidence and severity of cancer therapy-related side effects, the impact of other antiretroviral agents on the tolerability and response to chemotherapy is less well documented. We report the successful use of an etravirine-based regimen in a patient treated with BEACOPP chemotherapy for advanced Hodgkin's lymphoma. Etravirine constitutes a valuable option for concomitant use with chemotherapy due to its moderate inducing effect on drug metabolising enzymes.

    2017-01-01

    Hepatic sinusoidal obstruction syndrome (SOS), a serious complication that mainly occurs after hematopoietic-stem cell transplantation (HSCT), is caused by damage to the sinusoidal endothelial cells after the obstruction of the sinusoid. Recently, hepatic SOS was reported to occur after non-HSCT chemotherapies. This report describes a patient who experienced hepatic SOS after non-HSCT chemotherapy for non-Hodgkin lymphoma. A liver biopsy showed the slight dilatation of the hepatic sinusoid, which may be indicative of hepatic SOS. Hepatic SOS should be included in the differential diagnosis of patients with severe liver injury following the administration of chemotherapy regimens that are toxic to the vascular endothelial cells.

After extensive investigations, he was diagnosed with cancer-related microangiopathic haemolytic anaemia (CR-MAHA) secondary to gastric adenocarcinoma. Initial treatment with plasmapheresis was ineffective, but the patient’s haematological abnormalities improved markedly with chemotherapy directed against his gastric cancer. Our case amplifies previous experience of gastric cancer-associated MAHA which responded to treatment with chemotherapy. We review current understanding of the proposed pathophysiology of CR-MAHA and conclude that this condition is ideally treated with chemotherapy.

    Full Text Available For many years, surgery alone was the standard treatment for patients with stage I-IIIA non-small-cell lung cancer (NSCLC. However, recent studies have demonstrated that adjuvant chemotherapy provides a survival benefit. The first adjuvant chemotherapy for NSCLC was performed in the 1960s using a key drug known as cyclophosphamide. In the 1980s and early 1990s, a new anti-cancer drug, cisplatin, was developed. The first meta-analysis of this drug was conducted by the Non-small Cell Lung Cancer Collaborative Group in 1995. This analysis comparing surgery with surgery plus chemotherapy containing cisplatin produced a hazard ratio of 0.87 and suggested an absolute benefit of chemotherapy of 5% at 5 years;this difference was not statistically significant (p0.08. Several clinical trials of adjuvant chemotherapy were planned after the meta-analysis conducted in 1995, but the efficacy of adjuvant chemotherapy remained a matter of controversy. However, useful evidence was reported after 2003. The International Adjuvant Lung Cancer Collaborative Group Trial (IALT demonstrated a 4.1% improvement in survival for patients with stage I to III NSCLC. The JBR. 10 trial demonstrated a 15% improvement in 5-year survival for the adjuvant chemotherapy arm in stage IB or II (excluding T3N0 patients. The Adjuvant Navelbine International Trialist Association (ANITA trial reported that the overall survival at 5 years improved by 8.6% in the chemotherapy arm and that this survival rate was maintained at 7 years (8.4% in stage II and IIIA patients. A meta-analysis based on collected and pooled individual patient data from the 5 largest randomized trials was conducted by the Lung Adjuvant Cisplatin Evaluation (LACE. This analysis demonstrated that cisplatin-based adjuvant chemotherapy improved survival in patients with stage II or III cancer. Alterna-tively, uracil-tegafur has been developed and tested in Japan.

    We described 3 cases of stomatitis caused by chemotherapy with the fluoropyrimidine preparation S-1, alone or combined with other anticancer drugs. The stomatitis did not respond to conventional oral mucosal treatment such as triamcinolone acetonide(Kenalog)or allopurinol, but improved after treatment with the histamine H2-receptor antagonist lafutidine. The concurrent use of lafutidine allowed these 3 patients to continue chemotherapy with no recurrence of stomatitis. We concluded that lafutidine may be a viable treatment option for chemotherapy-induced stomatitis, allowing treatment to be continued.

    2015-01-01

    Objective:We aimed to evaluate the effectiveness and safety of intravenous (IV) plus intraperitoneal (IP) chemotherapy compared to IV chemotherapy alone for patients with gastric cancer.Methods: Electronic databases were searched up to June 2013. Two authors independently assessed the quality of included studies. hTe GARDE System was adopted to rate the level of evidence. Of 392 citations, ifve RCTs involving 1, 072 patients were included.Results:Overall, a signiifcant improvement in in 1- and 3- and 5-year survival rate was observed in the IV plus IP chemotherapy group (3 RCTs,n=360, RR=1.10, 95% CI, 1.04~1.17), (5 RCTs,n=953, RR=1.22, 95% CI, 1.11~1.35) and (3 RCTs, n=347, RR=1.42, 95% CI, 1.12~1.80), respectively. Results supported a signiifcant decrease in the rate of metastases (1 RCT,n=85, RR=0.41 95% CI, 0.19~0.89) and peritoneal recurrence (2 RCTs,n=297, RR=0.41, 95% CI, 0.26~0.62) in the IV plus IP chemotherapy group, however, the incidence of adverse events was increased.Conclusion:For patients with gastric cancer, IV plus IP chemotherapy can improve the overall survival rate and prevent the distant or peritoneal metastases. An increased risk of neutropenia, peripheral edema and neuropathy was observed.

    Full Text Available SummaryIntroduction:chemotherapy is essential to treat most types of cancer. Often, there is chemotherapy waste in the preparation of drugs prescribed to the patient. Leftover doses result in toxic waste production.Objective:the aim of the study was to analyze chemotherapy waste reduction at a centralized drug preparation unit.Methods:the study was cross-sectional, observational and descriptive, conducted between 2010 and 2012. The data were obtained from chemotherapy prescriptions made by oncologists linked to a health insurance plan in Curitiba, capital of the state of Paraná, in southern Brazil. Dose and the cost of chemotherapy waste were calculated in each application, considering the dose prescribed by the doctor and the drug dosages available for sale. The variables were then calculated considering a hypothetical centralized drug preparation unit.Results:there were 176 patients with a cancer diagnosis, 106 of which underwent treatment with intravenous chemotherapy. There were 1,284 applications for intravenous anticancer medications. There was a total of 63,824mg in chemotherapy waste, the cost of which was BRL 448,397.00. The average cost of chemotherapy waste per patient was BRL 4,607.00. In the centralized model, there was 971.80mg of chemotherapy waste, costing BRL 13,991.64. The average cost of chemotherapy waste per patient was BRL 132.00.Conclusion:the use of centralized drug preparation units may be a strategy to reduce chemotherapy waste.

  12. Clozapine reinitiation following a "red result" secondary to chemotherapy

    Full Text Available Tariq Munshi, Mir Mazhar, Tariq HassanDepartment of Psychiatry, Kingston General Hospital, Kingston, ON, CanadaAbstract: We describe a case of a patient whose clozapine was discontinued after a "red result" following R-CHOP (rituximab with cyclophosphamide, hydroxydaunorubicin, Oncovin, and prednisolone chemotherapy for large B-cell lymphoma. In some cases, manufacturers grant permission, on compassionate grounds, for clozapine to be continued or reinitiated following assessment by their consultant hematologist. Other than a recent case report, there is not much literature surrounding this medical issue. However, since the two leading causes of mortality in schizophrenia are cancer and cardiac disease, this is not an uncommon occurrence. Clinicians are reluctant to prescribe clozapine in view of its side-effect profile, despite its proven efficacy for managing treatment-resistant schizophrenia. The alternative is to prescribe two antipsychotics to manage symptoms. This approach may be associated with increased side effects, and evidence for actual benefits is scant. The consequences were disastrous in this case, as the individual not only relapsed following clozapine discontinuation, but the therapy for this treatable form of lymphoma had to be delayed. He was eventually admitted to an inpatient unit after having been stable for 15 years. We managed to stabilize him with olanzapine and aripiprazole which enabled the heme-oncology group to resume R-CHOP therapy with filgrastim (granulocyte colony-stimulating factor. Even so, he continued to exhibit severe psychotic symptoms, with religious delusions and auditory hallucinations. We therefore applied for permission to rechallenge him on clozapine. Permission was granted when protocol conditions were met, and reinitiation went without any adverse events. The patient's symptoms showed improvement within a few weeks, and the other antipsychotics were discontinued once clozapine was titrated up to 300

  13. Combined radiotherapy and chemotherapy for high-grade brain tumours

    Science.gov (United States)

    Barazzuol, Lara

    Glioblastoma (GBM) is the most common primary brain tumour in adults and among the most aggressive of all tumours. For several decades, the standard care of GBM was surgical resection followed by radiotherapy alone. In 2005, a landmark phase III clinical trial coordinated by the European Organization for Research and Treatment of Cancer (EORTC) and the National Cancer Institute of Canada (NCIC) demonstrated the benefit of radiotherapy with concomitant and adjuvant temozolomide (TMZ) chemotherapy. With TMZ, the median life expectancy in optimally managed patients is still only 12-14 months, with only 25% surviving 24 months. There is an urgent need for new therapies in particular in those patients whose tumour has an unmethylated methylguanine methyltransferase gene (MGMT) promoter, which is a predictive factor of benefit from TMZ. In this dissertation, the nature of the interaction between TMZ and radiation is investigated using both a mathematical model, based on in vivo population statistics of survival, and in vitro experimentation on a panel of human GBM cell lines. The results show that TMZ has an additive effect in vitro and that the population-based model may be insufficient in predicting TMZ response. The combination of TMZ with particle therapy is also investigated. Very little preclinical data exists on the effects of charged particles on GBM cell lines as well as on the concomitant application of chemotherapy. In this study, human GBM cells are exposed to 3 MeV protons and 6 MeV alpha particles in concomitance with TMZ. The results suggest that the radiation quality does not affect the nature of the interaction between TMZ and radiation, showing reproducible additive cytotoxicity. Since TMZ and radiation cause DNA damage in cancer cells, there has been increased attention to the use of poly(ADP-ribose) polymerase (PARP) inhibitors. PARP is a family of enzymes that play a key role in the repair of DNA breaks. In this study, a novel PARP inhibitor, ABT-888

    The most recent acquisitions on chemotherapy and chemoprophylaxis of malaria are reviewed. With regard to chemotherapy, candidate antimalarial compounds have been divided into four groups, according to their stages of development. Mefloquine and the combination of mefloquine with sulfadoxine/pyrimethamine belong to the first group: they have completed clinical trials and have been registered in several countries for routine clinical use. The second group is characterized by chemical compounds which are in an advanced stage of development, including clinical trials. The compounds considered in this group are: a) the 9-phenanthrenemethanols, among which halofantrine is the most promising one; b) the sesquiterpene lactones such as Qinghaosu, artemether, artesunate, artesunic acid and arteether which must be further tested in order to find more effective drug regimens capable of eliminating recrudescences and for the completion of toxicity studies; c) pyronaridine, which appears to be a promising antimalarial, effective also against chloroquine-resistant P. falciparum, but still requiring further investigations on resistance and cross-resistance, as well as its pharmacokinetics, tolerability and bioavailability; d) enpiroline, another promising compound, which needs to be further studied in Phase II and Phase III investigations with naturally acquired malaria. The third group is composed of seven chemical classes of compounds that are in an advanced pre-clinical development, namely: the 4-aminoquinolines, such as dabechin, piperaquine, hydroxypiperaquine, tripiperaquine, dichlor-quinazine and the Mannich base compounds, the 8-aminoquinolines, the 4-quinolinemethanols, the quinolones, the naphthoquinones, the quinazolines and the dihydrotriazines. Among the many antimalarial compounds of interest, which can be considered at the moment as leads for further studies, only the acridandione derivatives such as floxacrine, the antibiotics, antifungal agents or their

  15. The risk of amenorrhea is related to chemotherapy-induced leucopenia in breast cancer patients receiving epirubicin and taxane based chemotherapy.

    Wenbin Zhou

    Full Text Available BACKGROUND: Chemotherapy-induced amenorrhea (CIA is common in young breast cancer patients. The incidence of CIA associated with regimens involving epirubicin and taxane was not well known. Furthermore, previous studies suggested leucopenia and amenorrhea may reflect inter-individual variations in pharmacokinetics. The purpose of this study was to investigate the association between leucopenia after first cycle of chemotherapy and CIA in young breast cancer patients receiving epirubicin and taxane based chemotherapy. Furthermore, the incidence of CIA was also assessed. METHODOLOGY AND PRINCIPAL FINDINGS: Between October 2008 and March 2010, 186 consecutive premenopausal patients, treated with epirubicin and taxane based chemotherapy, were recruited. Information about CIA was collected by telephone and out-patient clinic. Of these 186 patients, data from 165 patients were included and analyzed. Of all 165 patients, CIA occurred in 72 patients (43.64%. In multivariate analysis, age older than 40 y (OR: 16.10, 95% CI: 6.34-40.88, P0.05. The rate of CIA in leucopenia group (52.56% was significantly higher than that in normal leukocyte group (34.62% (P = 0.024. In patients treated with a FEC regimen (cyclophosphamide, epirubicin and 5-fluorouracil, the rate of CIA in leucopenia group (59.57% was significantly higher than that in normal leukocyte group (36.84% (P = 0.037. CONCLUSIONS: Age at diagnosis and previous childbearing were both found to significantly increase the risk of CIA, whereas additional taxane was not associated with increased rate of CIA. Importantly, leucopenia after first cycle of chemotherapy was associated with increased risk of CIA, which suggested that leucopenia may be an early predictor of chemotherapy-induced infertility.

    2016-01-01

    ABSTRACT Objective: to identify factors related to the nursing diagnosis nausea among cancer patients undergoing chemotherapy. Method: integrative review conducted in four electronic databases (PUBMED, EMBASE, CINAHL and LILACS) using the key words: neoplasia, antineoplastic agents and nausea. Results: only 30 out of 1,258 papers identified met the inclusion criteria. The most frequent related factors were: being younger than 50 years old, motion sickness, being a woman, emetogenic potential of the chemotherapy, anxiety, conditioned stimulus, and expecting nausea after treatment. Conclusion: this review's findings, coupled with the incidence of nausea among cancer patients undergoing chemotherapy, reveal an important difference between evidence found and that used by NANDA International, Inc. Even though it provides an appropriate definition of related factors, it does not mention chemotherapy, despite the various studies addressing the topic using different designs and presenting various objectives and outcomes.

    Full Text Available Background. The standard initial management of patients with locally advanced pharyngolaryngeal presenting with stridor is tracheostomy. Tracheostomy has been shown to negatively impact cancer-related outcomes. Methods. Retrospective analysis of prospectively collected data of 9 patients, who underwent induction chemotherapy with the aim of prevention of tracheostomy. Presenting features, time to resolution of stridor, and further management are reported. Results. Eight out of 9 patient received chemotherapy within 12 hours of presentation with stridor. There were 4 patients each with primary hypopharynx and larynx. The stage was IVA in 6 patients and IVB in 2 patients. In all patients receiving immediate chemotherapy, clinical stridor resolved within 48 hours. The radiological response rate was 62.5%. The median reduction in size of tumor was 37%. Conclusion. Immediate neoadjuvant chemotherapy is a feasible and safe option for patients presenting with early stridor and helps in resolution of stridor and avoiding tracheostomy.

    in cancer. In this regard, several studies have demonstrated an antiapoptotic effect of TIMP-1 in a number of different cell types. Since chemotherapy works by inducing apoptosis in cancer cells, we raised the hypothesis that TIMP-1 promotes resistance against chemotherapeutic drugs. In order to investigate...... this hypothesis, we have established TIMP-1 gene-deficient and TIMP-1 wild-type fibrosarcoma cells from mouse lung tissue. We have characterised these cells with regard to TIMP-1 genotype, TIMP-1 expression, malignant transformation and sensitivity to chemotherapy-induced apoptosis. We show that TIMP-1 gene...... deficiency increases the response to chemotherapy considerably, confirming that TIMP-1 protects the cells from apoptosis. This is to our knowledge the first study investigating TIMP-1 and chemotherapy-induced apoptosis employing a powerful model system comprising TIMP-1 gene-deficient cells...

    In order to discuss the role of preoperative chemotherapy for colorectal liver metastases, which is used frequently before hepatic resection, even in patients with resectable disease at presentation, we herein report the development of two complications, partial portal vein thrombosis and hepatic steatosis with lobular inflammation, during the course of preoperative chemotherapy with FOLFIRI plus bevacizumab for colorectal liver metastases, which recognition led to timely discontinuation of chemotherapy as well as a change in the surgical strategy to resect the tumors and the damaged liver through advanced techniques.We conclude that duration of treatment and drug doses and combinations may impact the development of chemotherapy-induced liver injury. Surgeons and medical oncologists must work together to devise safe, rational,and oncologically appropriate treatments for patients with multiple colorectal liver metastases, and to improve the understanding of the pathogenesis of chemotherapyinduced liver injury.

    Cannabinoids (the active constituents of Cannabis sativa) and their derivatives have got intense attention during recent years because of their extensive pharmacological properties. Cannabinoids first developed as successful agents for alleviating chemotherapy associated nausea and vomiting. Recent investigations revealed that cannabinoids have a wide range of therapeutic effects such as appetite stimulation, inhibition of nausea and emesis, suppression of chemotherapy or radiotherapy-associated bone loss, chemotherapy-induced nephrotoxicity and cardiotoxicity, pain relief, mood amelioration, and last but not the least relief from insomnia. In this exploratory review, we scrutinize the potential of cannabinoids to counteract chemotherapy-induced side effects. Moreover, some novel and yet important pharmacological aspects of cannabinoids such as antitumoral effects will be discussed.

    Adjuvant chemotherapy for breast cancer after surgery has effectively lowered metastatic recurrence rates. However, a considerable proportion of women suffer recurrent cancer at distant metastatic sites despite adjuvant treatment. Identification of the genes crucial for tumor response to specific...... chemotherapy drugs is a challenge but is necessary to improve outcomes. By using integrated genomics, we identified a small number of overexpressed and amplified genes from chromosome 8q22 that were associated with early disease recurrence despite anthracycline-based adjuvant chemotherapy. We confirmed...... of LAPTM4B resulted in sequestration of the anthracycline doxorubicin, delaying its appearance in the nucleus. Overexpression of these two genes was associated with poor tumor response to anthracycline treatment in a neoadjuvant chemotherapy trial in women with primary breast cancer. Our results suggest...

    Full Text Available To evaluate the effectiveness of Uncaria tomentosa in minimizing the side effects of chemotherapy and improving the antioxidant status of colorectal cancer (CRC patients, a randomized clinical trial was conducted. Patients (43 undergoing adjuvant/palliative chemotherapy with 5-Fluorouracil/leucovorin + oxaliplatin (FOLFOX4 were split into two groups: the UT group received chemotherapy plus 300 mg of Uncaria tomentosa daily and the C group received only FOLFOX4 and served as a control. Blood samples were collected before each of the 6 cycles of chemotherapy, and hemograms, oxidative stress, enzymes antioxidants, immunologic parameters, and adverse events were analyzed. The use of 300 mg of Uncaria tomentosa daily during 6 cycles of FOLFOX4 did not change the analyzed parameters, and no toxic effects were observed.

  1. Chemotherapy-induced peripheral neuropathy: an update on the current understanding.

    Addington, James; Freimer, Miriam

    2016-01-01

    Chemotherapy-induced peripheral neuropathy is a common side effect of selected chemotherapeutic agents. Previous work has suggested that patients often under report the symptoms of chemotherapy-induced peripheral neuropathy and physicians fail to recognize the presence of such symptoms in a timely fashion. The precise pathophysiology that underlies chemotherapy-induced peripheral neuropathy, in both the acute and the chronic phase, remains complex and appears to be medication specific. Recent work has begun to demonstrate and further clarify potential pathophysiological processes that predispose and, ultimately, lead to the development of chemotherapy-induced peripheral neuropathy. There is increasing evidence that the pathway to neuropathy varies with each agent. With a clearer understanding of how these agents affect the peripheral nervous system, more targeted treatments can be developed in order to optimize treatment and prevent long-term side effects.

    Chemotherapy-induced nausea and vomiting is a significant clinical issue which affects patient's quality of life and treatment decisions. Significant improvements in the control of chemotherapy-induced nausea and vomiting have occurred in the past 15 years with the introduction of new antiemetic agents 5-HT3, receptor antagonists, neurokinin-1 (NK-1) receptor antagonists, and olanzapine. Aprepitant was the first NK-1 receptor antagonist introduced (2003) for the prevention of chemotherapy-induced nausea and vomiting in combination with a 5-HT3 receptor antagonist and dexamethasone. A second NK-1 receptor antagonist netupitant was approved for use in October 2014. Phase III clinical trials of an additional NK-1 receptor antagonist rolapitant have been completed, and the data have been submitted for regulatory approval. A description of rolapitant and its role in chemotherapy-induced nausea and vomiting will be presented, along with a comparison of the other neurolinin-1 receptor antagonists aprepitant and netupitant.

    A brief review is made of the research in the field of antiviral chemotherapy performed in the "Stefan S. Nicolau" Institute of Virology during the 35 years since its foundation. The investigations have mainly focused on influenza and herpes virus, but the chemotherapy of other viral infections (mumps, vaccinia, Coxsackie, etc.) has also been approached. Most of the chemotherapy agents assayed have been represented by natural preparations: immunoglobulins, interferon, hormones, vitamins, plant extracts (garlic, horse radish), bee products (propolis, royal jelly); attempts have also been made with numerous synthetic compounds. Stress is laid on the preparations already tested with a view to application in human clinic, and the prospects of chemotherapy research in the Institute of Virology are discussed.

    In this work we investigate a mathematical model describing tumour growth under a treatment by chemotherapy that incorporates time-delay related to the conversion from resting to hunting cells. We study the model using values for the parameters according to experimental results and vary some parameters relevant to the treatment of cancer. We find that our model exhibits a dynamical behaviour associated with the suppression of cancer cells, when either continuous or pulsed chemotherapy is applied according to clinical protocols, for a large range of relevant parameters. When the chemotherapy is successful, the predation coefficient of the chemotherapic agent acting on cancer cells varies with the infusion rate of chemotherapy according to an inverse relation. Finally, our model was able to reproduce the experimental results obtained by Michor and collaborators [Nature 435 (2005) 1267] about the exponential decline of cancer cells when patients are treated with the drug glivec.

    2011-10-01

    A 71-year-old man was admitted to our hospital in September 2009 because of severe headache due to meningeal carcinomatosis. In July 2007, subtotal gastrectomy was carried out for gastric cancer. Because intraabdominal cytodiagnosis was positive, he received systemic chemotherapy for 2 years. Recurrent signs were not found on chest or abdominal CT just before hospitalization. He was given NSAIDs and corticosteroid, but his symptom did not improve. Subsequent intrathecal chemotherapy with MTX and Ara-C improved clinical symptoms dramatically. He received care at home for 3 months before he passed away due to pleural and peritoneal recurrence. Recently, since the frequency of meningeal carcinomatosis is increasing, combination treatment of intrathecal chemotherapy and systemic chemotherapy should be considered not only for improvement of clinical manifestations, but also for prognostic improvement.

  10. Polyamine catabolism in carcinogenesis: potential targets for chemotherapy and chemoprevention.

    Science.gov (United States)

    Battaglia, Valentina; DeStefano Shields, Christina; Murray-Stewart, Tracy; Casero, Robert A

    2014-03-01

    Polyamines, including spermine, spermidine, and the precursor diamine, putrescine, are naturally occurring polycationic alkylamines that are required for eukaryotic cell growth, differentiation, and survival. This absolute requirement for polyamines and the need to maintain intracellular levels within specific ranges require a highly regulated metabolic pathway primed for rapid changes in response to cellular growth signals, environmental changes, and stress. Although the polyamine metabolic pathway is strictly regulated in normal cells, dysregulation of polyamine metabolism is a frequent event in cancer. Recent studies suggest that the polyamine catabolic pathway may be involved in the etiology of some epithelial cancers. The catabolism of spermine to spermidine utilizes either the one-step enzymatic reaction of spermine oxidase (SMO) or the two-step process of spermidine/spermine N (1)-acetyltransferase (SSAT) coupled with the peroxisomal enzyme N (1)-acetylpolyamine oxidase. Both catabolic pathways produce hydrogen peroxide and a reactive aldehyde that are capable of damaging DNA and other critical cellular components. The catabolic pathway also depletes the intracellular concentrations of spermidine and spermine, which are free radical scavengers. Consequently, the polyamine catabolic pathway in general and specifically SMO and SSAT provide exciting new targets for chemoprevention and/or chemotherapy.

    Full Text Available Grapevine fleck virus produces a ubiquitous disease, latent in European grapevine varieties (Vitis vinifera L. and in most American rootstocks, being found in all viticultural countries, in simple or complex infections with other more dangerous viruses. Different techniques for sanitation showed controversial results regarding fleck elimination in grapevine. In vitro culture of ‘Tămâioasă românească’ 3-2-2 with fleck virus and ‘Burgund’ 63 Mn with double infection (Grapevine fleck virus and Grapevine virus A, naturally infected have been submitted to hemotherapy using a combination of ribavirin and oseltamivir in three concentration variants (V1-40 mg/L ribavirin + 40 mg/L oseltamivir; V2-20 mg/L ribavirin + 40 mg/L oseltamivir; V3-20 mg/L ribavirin + 80 mg/L oseltamivir and three consecutive subcultures. The plants regenerated after each subculture were evaluated by ELISA from the viewpoint of virus elimination and the RT-PCR was used for confirmation of the diagnostic. Due the phytotoxic effect of viricides, the ltiplication rate decreased on experimental variants in the next subculture comparatively to the control, but no mortality of explants has been registered. Grapevine fleck virus has been 100% eliminated both from simple and mixed infections on all variants by in vitro chemotherapy, under the simultaneous action of two viricides. Unsatisfactory results have been achieved with Grapevine virus A elimination.

    1988-01-01

    During the last 30 years, many chemical compounds that are active against tumors have been discovered or developed. At the same time, new methods of testing drugs for cancer therapy have evolved. nefore 1964, drug testing on animal tumors was directed to observation of the incfease in life span of the host after a single dose. A new approach, in which the effects of multiple doses on the proliferation kinetics of the tumor in vivo as well as of cell lines in vitro are investigated, has been outlined by Skipper and his co-workers in a series of papers beginning in 1964 (Skipper, Schabel and Wilcox, 1964 and 1965). They also investigated the influence of the time schedule in the treatment of experimental tumors. Since the publication of those studies, cell population kinetics cannot be left out of any discussion of the rational basis of chemotherapy. When clinical oncologists began to apply cell kinetic concepts in practice about 15 years ago, the theoretical basis was still very poor, in spite of Skipper's pro...

    We summarize the cases of four women with acute myeloid leukemia (AML) and of one with acute lymphoid leukemia (ALL) presenting in the first, second and third trimester of pregnancy. Remission of AML was induced by doxorubicin, vincristine, and cytosine arabinoside. The ALL case was treated with vincristine and prednisone initially, and subsequently with vindesine for maintenance. Four patients entered a complete (3 AML and the ALL case), and one (AML) a partial remission. This patient was delivered of a normal, 3140 g, male infant by Caesarian section in the 38th gestational week and 1 month later she died of her disease. One patient (AML, promyelocytic type) who presented in the 10th week of pregnancy underwent elective abortion while in remission after induction treatment. The patient with ALL gave birth to a normal, full-term, male infant by Caesarian section. The two other patients (AML) had spontaneous deliveries of normal male infants in the 37th and 38th weeks of pregnancy. Growth and development of three of the children are normal at 12, 36, and 37 months of life while the fourth child was lost to follow-up evaluation. The disease relapsed in all mothers but they are still alive at 15 (ALL), 37, and 42 months after diagnosis. We feel that current chemotherapy could improve the high post-partum maternal mortality rate and the chance of producing live babies without excessive risk to the fetus or the mother, even if administered relatively early in the course of pregnancy.

    1993-04-01

    From July 1988 to February 1991, 130 children with the tentative diagnosis of nephroblastoma were treated preoperatively. The initial diagnostic images (excretory urography, ultrasound, CT, MRI) have been analysed both prospectively and retrospectively and the findings correlated with the intraoperative and histological results. Of the preoperatively treated patients 93.8% had a Wilms` tumour or one of its variants. Five patients had a different malignant tumour and 3 patients, i.e. 2.3% of those preoperatively treated or 1.6% of all registered patients, had benign tumours of the kidney. Wilms` tumour generally presented as a well-defined mass with an inhomogeneous morphology on CT. On ultrasound only 24% of the tumours were homogeneous. Intratumoral haemorrhage and cystic areas occurred frequently; calcifications were rare (8%). With regard to caval involvement only ultrasound and MRI enabled the correct diagnosis, while CT could not differentiate compressions from invasion. The pretherapeutic diagnostic imaging was of sufficient accuracy to start preoperative chemotherapy without diagnostic biopsy. (orig.)

    Full Text Available Fibromatosis, or extra-abdominal desmoid tumor, is a benign disease which often has an aggressive clinical course that can be difficult to treat. We performed a retrospective review of 16 patients (12 females and four males with a mean age of 34.2 years treated with methotrexate and vinblastine for newly diagnosed or recurrent extra-abdominal desmoid tumor. The mean age of our patient cohort was 34.2 years (range 11–70, and the mean tumor size was 11.5 cm (range 2.5–21.2 cm. The mean duration of therapy was 12 months with an average follow-up of 43 months (range 1–149 months. Fourteen of 16 patients demonstrated a clinical response to treatment. Eight of 14 patients demonstrated a radiologic decrease in tumor size. Only one patient progressed on therapy. Six patients developed recurrent symptoms after discontinuation of treatment. Chemotherapy-related symptoms including neutropenia, nausea, and vomiting were common and observed in most patients, however these side effects were mild and transient. Five patients developed peripheral neuropathy that prompted a change from vinblastine to vinorelbine during treatment. One potentially life-threatening complication (pneumocystis pneumonia occurred which was diagnosed early and successfully treated. The use of methotrexate and vinblastine/vinorelbine in the management of fibromatosis appears to be an effective treatment with minimal treatment-related side effects.

  17. Enhancing chemotherapy response with Bmi-1 silencing in ovarian cancer.

    Directory of Open Access Journals (Sweden)

    Enfeng Wang

    Full Text Available Undoubtedly ovarian cancer is a vexing, incurable disease for patients with recurrent cancer and therapeutic options are limited. Although the polycomb group gene, Bmi-1 that regulates the self-renewal of normal stem and progenitor cells has been implicated in the pathogenesis of many human malignancies, yet a role for Bmi-1 in influencing chemotherapy response has not been addressed before. Here we demonstrate that silencing Bmi-1 reduces intracellular GSH levels and thereby sensitizes chemoresistant ovarian cancer cells to chemotherapeutics such as cisplatin. By exacerbating ROS production in response to cisplatin, Bmi-1 silencing activates the DNA damage response pathway, caspases and cleaves PARP resulting in the induction apoptosis in ovarian cancer cells. In an in vivo orthotopic mouse model of chemoresistant ovarian cancer, knockdown of Bmi-1 by nanoliposomal delivery significantly inhibits tumor growth. While cisplatin monotherapy was inactive, combination of Bmi-1 silencing along with cisplatin almost completely abrogated ovarian tumor growth. Collectively these findings establish Bmi-1 as an important new target for therapy in chemoresistant ovarian cancer.

    2011-01-01

    Peritoneal carcinomatosis in gastric cancer is associated with a dismal prognosis. Systemic chemotherapy is not effective because of the existence of a blood-peritoneal barrier. Cytoreductive surgery and intraperitoneal chemotherapy can improve survival and quality of life in selected patients. Patient selection for this multimodal approach is one of the most critical issues, and calls for interdisciplinary evaluation by radiologists, medical and surgical oncologists, and anaesthetists. This article sets forth criteria for selection of gastric cancer patients suffering from peritoneal carcinomatosis.

    Passik, S D; Kirsh, K L; Rosenfeld, B; McDonald, M V; Theobald, D E

    2001-02-01

    The side effects of chemotherapy are feared by cancer patients as they begin their treatment. In this study, we investigated patients' anticipatory fears about chemotherapy. We then re-assessed these fears three to six months after the initial interview for patients who received chemotherapy during that time. We also examined symptom distress at these intervals. Hair loss, vomiting, infection, nausea, and weight loss were ranked as the most feared side effects of cancer treatment for the group as they began treatment. Patients beginning chemotherapy endorsed frequent or intense levels of fatigue, worrying about the future, pain, and sleep problems. No differences were found in the reporting of symptoms based on gender, age, or educational level. While changes in symptom distress over the study period were unremarkable, changes in fears about chemotherapy were of interest. The most feared symptoms were re-ordered following the treatment experience. The endorsement of nausea and vomiting, alopecia, and loss of appetite decreased significantly. Thirty-five percent fewer chemotherapy patients reported vomiting as one of their most feared side effects; 45% fewer patients who received anti-emetics reported vomiting as one of their most feared side effects. Effective treatments, such as those that have been developed to treat acute chemotherapy-related emesis, can relieve the fears of patients on treatment. We conclude that patients' fears about treatment are fluid and malleable. Patients' fears of suffering related to chemotherapy treatment change in response to the provision of adequate management. We discuss the implications of these findings for palliative care education.

    The fields of phototherapy and of inorganic chemotherapy both have long histories. Inorganic photoactivated chemotherapy (PACT) offers both temporal and spatial control over drug activation and has remarkable potential for the treatment of cancer. Following photoexcitation, a number of different decay pathways (both photophysical and photochemical) are available to a metal complex. These pathways can result in radiative energy release, loss of ligands or transfer of energy to another species,...

  4. A sleeping phantom leg awakened following hemicolectomy, thrombosis, and chemotherapy: a case report

    2011-05-01

    Full Text Available Abstract Introduction We describe the case of a patient who experienced phantom pain that began 42 years after right above-the-knee amputation. Immediately prior to phantom pain onset, this long-term amputee had experienced, in rapid succession, cancer, hemicolectomy, chemotherapy, and thrombotic occlusion. Very little has been published to date on the association between chemotherapy and exacerbation of neuropathic pain in amputees, let alone the phenomenon of bringing about pain in amputees who have been pain-free for many decades. While this patient presented with a unique profile following a rare sequence of medical events, his case should be recognized considering the frequent co-occurrence of osteomyelitis, chemotherapy, and amputation. Case presentation A 68-year-old Australian Caucasian man presented 42 years after right above-the-knee amputation with phantom pain immediately following hemicolectomy, thrombotic occlusion in the amputated leg, and chemotherapy treatment with leucovorin and 5-fluorouracil. He exhibited probable hyperalgesia with a reduced pinprick threshold and increased stump sensitivity, indicating likely peripheral and central sensitization. Conclusion Our patient, who had long-term nerve injury due to amputation, together with recent ischemic nerve and tissue injury due to thrombosis, exhibited likely chemotherapy-induced neuropathy. While he presented with unique treatment needs, cases such as this one may actually be quite common considering that osteosarcoma can frequently lead to amputation and be followed by chemotherapy. The increased susceptibility of amputees to developing potentially intractable chemotherapy-induced neuropathic pain should be taken into consideration throughout the course of chemotherapy treatment. Patients in whom chronic phantom pain then develops, perhaps together with mobility issues, inevitably place greater demands on healthcare service providers that require treatment by various

    This is an update of a Cochrane review that was first published in Issue 1, 2009. Gestational trophoblastic neoplasia (GTN) is a rare but curable disease arising in the fetal chorion during pregnancy. Most women with low-risk GTN will be cured by evacuation of the uterus with or without single-agent chemotherapy. However, chemotherapy regimens vary between treatment centres worldwide and the comparable benefits and risks of these different regimens are unclear.

  8. The activity of etoposide (VP16) in combination chemotherapy against human bladder cancer cells in vitro

    OpenAIRE

    Objectives First objective was better understanding of the indications of chemotherapy in elderly with advanced cancer, tolerability and toxicity of chemotherapy in this age group. The second objective was to define current practice in chemotherapy for elderly people with advanced cancer for a selected group of patients treated in Institute of Oncology Bucharest (IOB). Materials and Methods The study makes a clinical analysis of medical records of 27 patients from the archive of Institute of Oncology Bucharest treated by the same doctor. Patients were selected according to: age ≥ 65 years, ECOG performance status 0–1, normal blood counts and blood biochemistry, histological confirmation of the diagnosis of cancer, patients should received at least 3 cycles of chemotherapy. We extract characteristics of the patients to see if they were a homogeneous group of patients and to compare them with data from the literature. Overall survival was calculated by the Kaplan Meyer curve. Results 295 patients more then 65 years were treated in our site in 2 years 2011, 2012. 93 patients received chemotherapy and only 27 patients were enrolled in this study following inclusion criteria. Common sites of cancer were lung and breast. The most used cytostatics for lung cancer was gemcitabine and carboplatine and cyclophosphamide, metotrexat and 5 fluorouracil for breast cancer. Toxicity was mild with the prevalence of hematologic toxicity. Overall survival without taking into account the type of cancer was 27.7 month. Conclusions For selected patients, chemotherapy was well tolerated and appears to prolong survival regardless of the location of cancer. The relatively small number of elderly patients who received chemotherapy is probably due to lack of compliance to treatment, the increased number of co-morbidities and evaluation of performance status only by the ECOG index known not to be good enough to establish the indication of chemotherapy.

    Abstract Background: Ovarian cancer (OC) is the 5th leading cause of cancer-related deaths around the world, and several chemotherapy regimens have been applied in the treatment of OC. We aim to compare toxicities of different chemotherapy regimens in the treatment of advanced ovarian cancer (AOC) using network meta-analysis. Methods: Literature research in Cochrane Library, PubMed, and EMBASE was performed up to November 2015. Eligible randomized controlled trials (RCTs) of different chemotherapy regimens were included. Network meta-analysis combined direct and indirect evidence to assess pooled odds ratios (ORs) and draw the surface under the cumulative ranking (SUCRA) curves. Results: Thirteen eligible RCTs were included in this network meta-analysis, including 8 chemotherapy regimens (paclitaxel + carboplatin [PC], pegylated liposomal doxorubicin [PLD] + carboplatin, carboplatin, gemcitabine + carboplatin, paclitaxel, PC + epirubicin, PC + topotecan, docetaxel + carboplatin). Gemcitabine + carboplatin regimen exerted higher incidence of anemia when compared with carboplatin and paclitaxel regimens. The incidence of febrile neutropenia of gemcitabine + carboplatin regimen was higher than that of PC, PLD + carboplatin, carboplatin, and PC + topotecan regimens. Topotecan PC + epirubicin regimen had a higher toxicity, comparing with PC, PLD + carboplatin, and PC + topotecan regimens. As for thrombocytopenia, gemcitabine + carboplatin chemotherapy regimen produced an obviously higher toxicity than PC and carboplatin. As for nausea, PLD + carboplatin chemotherapy regimen had a significantly higher toxicity than that of carboplatin chemotherapy regimen. Moreover, when compared with PC and carboplatin chemotherapy regimens, the toxicity of PC + epirubicin was greatly higher to patients with AOC. Conclusion: The nonhematologic toxicity of PLD + carboplatin regimen was higher than other regimens, which

    2005-03-01

    Background: cognitive effects after cranial radiotherapy are widely discussed, but there is growing evidence that chemotherapy may also induce changes in neuropsychological functioning. This review summarizes the published literature regarding cognitive functioning after cancer therapy in adult patients. Material and methods: 63 reports from January 1980 to July 2003 assessing objective cognitive effects of irradiation and/or chemotherapy by neuropsychologic evaluation were analyzed. 57 studies with 3,424 patients were included for evaluation. Results: the results of this review confirm that both chemotherapy and irradiation can result in cognitive deficits. No clinically relevant differences are found for cognitive deficits, cognitive impairment rate, and single cognitive domains, when chemotherapy, cranial irradiation and combined radio- and chemotherapy were compared. Only 28 trials with 1,000 patients report quantitative data on patients with cognitive deficits after therapy. There are 44.1% (range 18-75%) of 451 patients in the chemotherapy group, 44.0% (range 29-83%) of 320 patients in the radiotherapy group, and 64.5% (range 30-100%) of 229 patients in the combined irradiation and chemotherapy group with cognitive deficits. Furthermore, cognitive functioning below average before chemo- or radiotherapy is found in subgroups of cancer patients. Conclusion: there is evidence of cognitive impairment in adult tumor patients after chemotherapy similar to effects after cranial irradiation. Cognitive functioning below average before therapy may be due to paraneoplastic effects. More prospective studies with a long-term follow-up using standardized neuropsychometric testing, assessment of premorbid intelligence, and suited control groups are needed. (orig.)

    Chemotherapy improves the outcome of cancer treatment, but patients are sometimes forced to discontinue chemotherapy or drop out of a clinical trial due to adverse effects, such as gastrointestinal disturbances and suppression of bone marrow function. The objective of this study was to evaluate the safety and effectiveness of a mushroom product, active hexose correlated compound (AHCC), on chemotherapy-induced adverse effects and quality of life (QOL) in patients with cancer. Twenty-four patients with cancer received their first cycle of chemotherapy without AHCC and then received their second cycle with AHCC. During chemotherapy, we weekly evaluated adverse effects and QOL via a blood test, EORTC QLQ-C30 questionnaire, and DNA levels of herpes virus type 6 (HHV-6) in saliva. The DNA levels of HHV-6 were significantly increased after chemotherapy. Interestingly, administration of AHCC significantly decreased the levels of HHV-6 in saliva during chemotherapy and improved not only QOL scores in the EORTC QLQ-C30 questionnaire but also hematotoxicity and hepatotoxicity. These findings suggest that salivary HHV-6 levels may be a good biomarker of QOL in patients during chemotherapy, and that AHCC may have a beneficial effect on chemotherapy-associated adverse effects and QOL in patients with cancer undergoing chemotherapy.

    Objective This study is to find valid medication to improve the condition of bone marrow suppress in a short period of time after chemotherapy of female genitalia cancer and to create a condition for second - time chemotherapy. Method Thirty- five cases using rhG- CSF were included in the experiment group while cases without rhG - CSF were set as control group. The wbc level in two groups are compared. Result The comparison shows that wbc resumes normal within 22 days in the experiment group while 35 days in the control group. The duration is 13 days less in the experiment group than the control group. From the 21st day after chemotherapy, patients in the experiment group need 2.5 days before another chemotherapy while 12 days for the control group. The average account of wbc in the experiment group is 9.5 × 109/L while 6.2 × 109/L in the control group. The variation in the comparison of 3 groups of data is statistically significant (P < 0.05). Conclusion The above results show that rhG - CSF has positive efficacy on the treatment of bone marrow suppress after chemotherapy of female genitalia cancer and helps the regular chemotherapy proceed smoothly.

  9. Chemotherapy options for the elderly patient with advanced non-small cell lung cancer.

    Hennessy, B T

    2012-02-03

    Combination chemotherapy has been shown to improve overall survival compared with best supportive care in patients with advanced non-small cell lung cancer (NSCLC). The survival advantage is modest and was initially demonstrated with cisplatin-containing regimens in a large meta-analysis of randomized trials reported in 1995. Newer chemotherapy combinations have been shown to be better tolerated than older cisplatin-based combinations, and some trials have also shown greater efficacy and survival benefits with these newer combinations. Combination chemotherapy is, therefore, the currently accepted standard of care for patients with good performance statuses aged less than 70 years with advanced NSCLC. However, there are limited data from clinical trials to support the use of combination chemotherapy in elderly patients over 70 years of age with advanced NSCLC. Subgroup analyses of large randomized phase III trials suggest that elderly patients with good performance statuses do as well as younger patients treated with combination chemotherapy. There are few randomized trials reported that evaluate chemotherapy in patients aged greater than 70 years only. Based on data from trials performed by an Italian group, single-agent vinorelbine has been shown to have significant activity in elderly patients with advanced NSCLC and to be well tolerated by those patients with Eastern Cooperative Oncology Group performance statuses of two or less, with associated improvements in measures of global health.

    OBJECTIVE To investigate the effect of neoadjuvant chemotherapy in treatment of Stage II breast cancer.METHODS The data from 113 patients with breast cancer of the same pathologic type in Stage II, during the period of 1995 to 2001, were analyzed retrospectively. Among the patients, 47 were treated with neoadjuvant chemotherapy, and 66 received no adjuvant therapy before surgery (control group). After the patients of the neoadjuvant chemotherapy group had received 2 courses of chemotherapy with the CMF regimen, the surgical procedure was conducted.RESULTS Complete remission (CR) was attained in 9 of the 47 cases receiving neoadjuvant chemotherapy and partial remission (PR) was reached for 22 cases. The rate of breast-conserving surgery was enhanced from 22.73% to 46.81% (P<0.05) in the neoadjuvant treatment group. There was no difference in the 5-year overall survival (OS) and disease-free survival (DFS) rate between the two groups (P>0.05), but the 5-year OS and DFS of the cases with clinical tumor remission was higher compared to the control group (P<0.05).CONCLUSION Neoadjuvant chemotherapy can enhance the rate of breast conservation for Stage II breast cancer and may improve the prognosis of the cases with clinical remission.

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

    2006-01-01

    The efficacy and safety of the recombinant mutant human tumor necrosis factor (rmhTNF) combined with chemotherapy vs chemotherapy alone in the treatment of patients with small cell lung cancer (SCLC) were evaluated in this study. The selected 37 patients with SCLC were divided into experimental group (n = 18) and control group (n = 19). Bothgroups were subjected to EP regimen. While in the experimental group, a regimen of 4 × 106 U/m2 rmhTNF intramuscular injection was given once a day from the 1st to 7th day and 11th to 17th day on the chemotherapy cycle.Twenty-one days were as a chemotherapy cycle and all patients received treatment with 2 cycles.The response rate was 83.3 % (15/18) in the experimental group and 63.2 % (12/19) in the control group respectively (P<0.05). The KPS score after treatment was 78.4±9.6 in the experimental group and 71.2±9.7 in the control group with the difference being significant (P<0.05).No severe adverse effects occurred in the two groups. It was concluded that the curative effectiveness of the rmhTNF combined with chemotherapy in the treatment of SCLC was more satisfactory than chemotherapy alone. The former could obviously improve the quality of life of the patients with SCLC.

    To retrospectively evaluate the prevalent location and size of pulmonary embolism (PE) in anti-neoplastic chemotherapy patients by multidetector row CT (MDCT). This study was conducted on 101 patients that were positively diagnosed with PE by CT. Among these patients, 23 had received or were undergoing chemotherapy. The location and the mean size of the largest PE were compared between anti-neoplastic chemotherapy patients and non-cancer patients using the Chisquare test and paired t-test, respectively. We also used a multiple linear regression to assess the risk posed by the other risk factors of PE. The most prevalent location of PE in patients on anti-neoplastic chemotherapy was in the lobar or segmental pulmonary arteries and was not significantly different from non-cancer patients. The size of the PE was smaller in patients on anti-neoplastic chemotherapy (1.14 mL [standard error = 0.29]) compared to non-cancer patients. (2.14 mL [standard error = 0.40]) (p < 0.05). The size of PE is smaller in anti-neoplastic chemotherapy patients than in non-cancer patients

    Chemotherapy followed by surgery for Stage IV gastric cancer with passage obstruction poses a problem in terms of poor postoperative nutritional status. By maintaining an adequate postoperative nutrition status with jejunostomy catheter feeding, chemotherapy may possibly be continued. We treated 40 cases of Stage IV gastric cancer with passage obstruction from January 2008 to December 2011. In every case, jejunostomy catheter feeding tubes were placed during gastric cancer surgery. We performed 13 total gastrectomies, 20 distal gastrectomies, and 7 gastrojejunal bypass surgeries. Tube obstruction in 4 cases( 10%) and tube deviation in 1 case( 2.5%) occurred during the tube feeding period. Chemotherapy could be resumed in 37 cases( 92.5%), and the duration of chemotherapy was 330 days( range, 41-721). In cases of Stage IV gastric cancer, patients are obliged to start postoperative chemotherapy at an unstable period. By starting jejunal catheter feeding at an early stage after surgery, improved results could be expected in terms of shortening of the hospital stay or continuation of chemotherapy.

    Purpose In women with early stage, estrogen-receptor (HR)-positive breast cancer, the 21-gene recurrence score (RS) assay quantifies recurrence risk and predicts chemotherapy responsiveness. Recent data suggest that not all women with early-stage, HR+ disease receive this testing. We examined socio-demographic, clinical, and attitudinal factors associated with RS testing receipt and the RS testing impact on chemotherapy use in Black and White patients. Patients and Methods Women with newly diagnosed invasive, non-metastatic breast cancer were recruited and interviewed to collect socio-cultural and healthcare process data; clinical data were collected from charts. Of the sample (n=359), 270 had HR-positive disease. Primary analysis focused on those with HR-positive node negative disease (n=143); secondary analyses included node positive women. Logistic regression models evaluated factors associated with receipt of RS testing and chemotherapy. Results Among women eligible for the 21-gene assay, 43% received RS testing. In multivariable analysis, higher age (OR=1.04 per one year increase; 95% CI: 1.01–1.08) was associated with RS testing adjusting for covariates. Chemotherapy use was 23%. In multivariable analysis, positive attitudes about chemotherapy and higher risk of recurrence were associated with chemotherapy use (p<.05). Conclusion Patterns of genomic testing may vary by age. Efforts to understand factors associated with low testing will be important. PMID:25555816

To prevent acute emesis, antiemetics should be administered just before chemotherapy and patients should be protected for up to 24 hours after chemotherapy initiation. The emetogenic potential of chemotherapeutic agents guides clinicians towards the most appropriate antiemetic prophylaxis. Current guidelines recommend the use of 5-HT3 receptor antagonist (RA either alone or in combination with dexamethasone and/or a neurokinin-1 RA both in the acute and delayed phases. The second-generation 5-HT3RA palonosetron exhibits a longer half-life and a higher binding affinity than older antagonists. Palonosetron has been approved by the FDA for the prevention of chemotherapy-induced nausea and vomiting (CINV in patients scheduled to receive either moderately (MEC or highly emetogenic chemotherapy (HEC and for the prevention of delayed CINV in patients receiving MEC. The present review will discuss the role of palonosetron in the prevention of acute CINV.Keywords: antiemetics, chemotherapy, nausea, vomiting, serotonin-receptor antagonists, palonosetron

    AIM: Preoperative intra-arterial infusion chemotherapy could increase the radical resection rate of advanced gastric cancer, but its effect on the long-term survival has not been assessed. This study was designed to evaluate the clinical significance of preoperative intra-arterial infusion chemotherapy for advanced gastric cancer.METHODS: Clinicopathological data of 91 patients who underwent curative resection for advanced gastric cancer were collected. Among them, 37 patients undertaken preoperative intra-arterial infusion chemotherapy were used as the interventional chemotherapy group, and the remaining 54 patients as the control group. Eleven factors including clinicopathological variables, treatment procedures and molecular biological makers that might contribute to the long-term survival rate were analyzed using Cox multivariate regression analysis.RESULTS: The 5-year survival rate was 52.5% and 39.8%,respectively, for the interventional group and the control group (P<0.05). Cox multivariate regression analysis revealed that the TNM stage (P<0.001), preoperative intraarterial infusion chemotherapy (P = 0.029) and growth pattern (P = 0.042) were the independent factors for the long-term survival of patients with advanced gastric cancer.CONCLUSION: Preoperative intra-arterial infusion chemotherapy plays an important role in improving the prognosis of advanced gastric cancer.

    The administration of chemotherapy to children with cancer is a high-risk process that must be performed in a safe and consistent manner with high reliability. Clinical trials play a major role in the treatment of children with cancer; conformance to chemotherapy protocol requirements and accurate documentation in the medical record are critical. Inconsistencies in the administration and documentation of chemotherapy were identified as opportunities for errors to occur. A major process improvement was initiated to establish best practices for nurses who administer chemotherapy to children. An interdisciplinary team was formed to evaluate the current process and to develop best practices based on current evidence, protocol requirements, available resources, and safety requirements. The process improvement focused on the establishment of standardized and safe administration techniques, exact administration times, and consistent electronic documentation that could easily be retrieved in medical record audits. Quality improvement tools including SBAR (Situation, Background, Assessment, Recommendation), process mapping, PDSA (Plan, Do. Study, Act) cycles, and quality metrics were used with this process improvement. The team established best practices in chemotherapy administration to children that have proven to be safe and reliable. Follow-up data have demonstrated that the project was highly successful and improved accuracy, patient and nurse safety, and effectiveness of chemotherapy administration.

    After an initial response to chemotherapy, many patients with triple-negative breast cancer (TNBC) have recurrence of drug-resistant metastatic disease. Studies with TNBC cells suggest that chemotherapy-resistant populations of cancer stem-like cells (CSCs) with self-renewing and tumor-initiating capacities are responsible for these relapses. TGF-β has been shown to increase stem-like properties in human breast cancer cells. We analyzed RNA expression in matched pairs of primary breast cancer biopsies before and after chemotherapy. Biopsies after chemotherapy displayed increased RNA transcripts of genes associated with CSCs and TGF-β signaling. In TNBC cell lines and mouse xenografts, the chemotherapeutic drug paclitaxel increased autocrine TGF-β signaling and IL-8 expression and enriched for CSCs, as indicated by mammosphere formation and CSC markers. The TGF-β type I receptor kinase inhibitor LY2157299, a neutralizing TGF-β type II receptor antibody, and SMAD4 siRNA all blocked paclitaxel-induced IL8 transcription and CSC expansion. Moreover, treatment of TNBC xenografts with LY2157299 prevented reestablishment of tumors after paclitaxel treatment. These data suggest that chemotherapy-induced TGF-β signaling enhances tumor recurrence through IL-8-dependent expansion of CSCs and that TGF-β pathway inhibitors prevent the development of drug-resistant CSCs. These findings support testing a combination of TGF-β inhibitors and anticancer chemotherapy in patients with TNBC.

    Objective Shared medical appointments offer a novel approach to improve efficiency and quality of care consistent with the goals of the Institute of Medicine. Our objective was to develop and implement a shared medical appointment for gynecologic cancer patients initiating chemotherapy. Methods We first assessed the level of interest in shared medical appointments among our patients and providers through qualitative interviews. Both patients and providers identified pre-chemotherapy as an optimal area to pilot shared medical appointments. We subsequently created a multidisciplinary team comprised of physicians, advanced practice providers, nurses, pharmacists, administrators, health education specialists and members of the Quality Improvement Department to establish a Shared Medical Appointment and Readiness Teaching (SMART) program for all gynecologic oncology patients initiating chemotherapy with platinum- and/or taxane-based regimens. We developed a standardized chemotherapy education presentation and provided patients with a tool kit that consisted of chemotherapy drug education, a guide to managing side effects, advance directives, and center contact information. Results From May 9, 2014 to June 26, 2015, 144 patients participated in 51 SMART visits. The majority of patients had ovarian cancer and were treated with carboplatin/paclitaxel. Surveyed patients reported being highly satisfied with the group visit and would recommend shared medical appointments to other patients. Conclusions This model of care provides patient education within a framework of social support that empowers patients. Shared medical appointments for oncology patients initiating chemotherapy are both feasible and well accepted. PMID:26549108
