    To determine financial barriers that impede the utilization of screening and treatment services for breast cancer among Nigerian women from different socioeconomic groups. A descriptive study was carried out in 2013 among women attending the oncology clinic of a tertiary institution in Enugu, Southeast Nigeria. Data were collected from 270 women using an interviewer-administered questionnaire. The links between the influence of socioeconomic factors on barriers to the utilization of breast cancer screening and treatment services were examined. A total of 270 women were studied. The mean age was 34.69 (Standard deviation = 5.07) years. Half of the study participants were single 141 (51.3%), while 105 (38.2%) were married. Cost of medical treatment and not having insurance coverage was major financial barriers to utilization of screening and treatment services. The least poor and poor socioeconomic status (SES) groups utilized screening services and treatment more frequently than the very poor and poorest SES groups ( P = 0.034). There was no significant difference in the utilization of the different treatment options among the different socioeconomic groups with the exception of surgery (χ² = 11.397; P = 0.000). Financial barriers limit the ability of women, especially the poorest SES group, to utilize screening and treatment services for early diagnosis and treatment of breast cancer. Interventions that will improve financial risk protection for women with breast cancer or at risk of breast cancer are needed to ensure equitable access to screening and treatment services.

    Full Text Available Abstract Background Men with prostate cancer are often challenged to choose between conservative management and a range of available treatment options each carrying varying risks and benefits. The trade-offs are between an improved life-expectancy with treatment accompanied by important risks such as urinary incontinence and erectile dysfunction. Previous studies of preference elicitation for prostate cancer treatment have found considerable heterogeneity in individuals' preferences for health states given similar treatments and clinical risks. Methods Using latent class mixture model (LCA, we first sought to understand if there are unique patterns of heterogeneity or subgroups of individuals based on their prostate cancer treatment utilities (calculated time trade-off utilities for various health states and if such unique subgroups exist, what demographic and urological variables may predict membership in these subgroups. Results The sample (N = 244 included men with prostate cancer (n = 188 and men at-risk for disease (n = 56. The sample was predominantly white (77%, with mean age of 60 years (SD ± 9.5. Most (85.9% were married or living with a significant other. Using LCA, a three class solution yielded the best model evidenced by the smallest Bayesian Information Criterion (BIC, substantial reduction in BIC from a 2-class solution, and Lo-Mendell-Rubin significance of < .001. The three identified clusters were named high-traders (n = 31, low-traders (n = 116, and no-traders (n = 97. High-traders were more likely to trade survival time associated with treatment to avoid potential risks of treatment. Low-traders were less likely to trade survival time and accepted risks of treatment. The no-traders were likely to make no trade-offs in any direction favouring the status quo. There was significant difference among the clusters in the importance of sexual activity (Pearson's χ2 = 16.55, P = 0.002; Goodman and Kruskal tau = 0.039, P < 0.001. In

    Patients with differentiated thyroid cancer (DTC) often respond well to treatment but some become refractory to radioactive iodine (RAI) treatment, and treatment options are limited. Despite the humanistic and economic burden RAI refractory disease imposes on patients, published research concerning treatment patterns and health care resource utilization is sparse. Data were collected from an online retrospective chart review study in the US and five European Union (EU) countries (France, Germany, Italy, Spain, and UK) with physicians recruited from an online panel. Physicians (N=211) provided demographics, disease history, treatment information, and health care resource utilization for one to four of their patients with radioactive iodine refractory differentiated thyroid cancer (RR-DTC). The majority of the patients with RR-DTC (N=623) were female (56%), and their mean age was 58.2 years. In this sample, 63.2% had papillary thyroid cancer and 57.0% were in Stage IV when deemed RAI refractory. Patients with RR-DTC experienced regional recurrence in the thyroid bed/central neck area (25.3%) and had distant metastatic disease (53.6%). At the time data were collected, 50.7% were receiving systemic treatment. Of those, 78.5% were on first-line treatment and 62.7% were receiving multikinase inhibitors. Regional differences for prescribed treatments were observed; the US was more likely to have patients receiving multikinase inhibitors (79.2%) compared with UK (41.2%) and Italy (17.1%). Additional details regarding treatment patterns and resource utilization are discussed. The current study aimed to obtain a greater understanding of RR-DTC treatment globally. These results can assist in the development and implementation of treatment guidelines and ultimately enhance the care of patients with RR-DTC

    Purpose: This work investigates X-PACT (X-ray Psoralen Activated Cancer Therapy): a new approach for the treatment of cancer. X-PACT utilizes psoralen, a potent anti-cancer therapeutic with immunogenic anti-cancer potential. Psoralen therapies have been limited due to the requirement for psoralen activation by UVA light. X-PACT solves this challenge by activating psoralen with UV light emitted from novel non-tethered phosphors (co-incubated with psoralen) that absorb x-rays and reradiate (phosphoresce) at UV wavelengths. Methods: The efficacy of X-PACT was evaluated in both in-vitro and in-vivo settings. In-vitro studies utilized breast (4T1), glioma (CT2A) and sarcoma (KP-B) cell lines. Cells were exposed to X-PACT treatments where the concentrations of drug (psoralen and phosphor) and radiation parameters (energy, dose, and dose rate) were varied. Efficacy was evaluated primarily using flow cell cytometry to investigate treatment induced apoptosis. Methylene blue staining, and WST assays were also used. X-PACT was then evaluated in an in-vivo pilot study on BALBc mice with syngeneic 4T1 tumors, including control arms for X-PACT components. Analysis focused on tumor growth delay. Results: A multivariable regression analysis of 36 independent in-vitro irradiation experiments demonstrated that X-PACT induces significant tumor cell apoptosis and cytotoxicity on all three tumor cell lines in-vitro (p<0.0001). Neither psoralen nor phosphor alone had a strongly significant effect. The in-vivo studies show a pronounced tumor growth delay when compared to controls (42% reduction at 25 days, p=0.0002). Conclusions: These studies demonstrate for the first time a therapeutic effect for X-PACT, and provide a foundation and rationale for future studies. X-PACT represents a novel treatment approach in which well-tolerated low doses of x-ray radiation generate UVA light in-situ (including deep seated lesions) which in-turn photo-activates powerful anticancer therapeutics which

    WHAT'S KNOWN ON THE SUBJECT? AND WHAT DOES THE STUDY ADD?: Multiple treatment alternatives exist for localised prostate cancer, with few high-quality studies directly comparing their comparative effectiveness and costs. The present study is the most comprehensive cost-effectiveness analysis to date for localised prostate cancer, conducted with a lifetime horizon and accounting for survival, health-related quality-of-life, and cost impact of secondary treatments and other downstream events, as well as primary treatment choices. The analysis found minor differences, generally slightly favouring surgical methods, in quality-adjusted life years across treatment options. However, radiation therapy (RT) was consistently more expensive than surgery, and some alternatives, e.g. intensity-modulated RT for low-risk disease, were dominated - that is, both more expensive and less effective than competing alternatives. To characterise the costs and outcomes associated with radical prostatectomy (open, laparoscopic, or robot-assisted) and radiation therapy (RT: dose-escalated three-dimensional conformal RT, intensity-modulated RT, brachytherapy, or combination), using a comprehensive, lifetime decision analytical model. A Markov model was constructed to follow hypothetical men with low-, intermediate-, and high-risk prostate cancer over their lifetimes after primary treatment; probabilities of outcomes were based on an exhaustive literature search yielding 232 unique publications. In each Markov cycle, patients could have remission, recurrence, salvage treatment, metastasis, death from prostate cancer, and death from other causes. Utilities for each health state were determined, and disutilities were applied for complications and toxicities of treatment. Costs were determined from the USA payer perspective, with incorporation of patient costs in a sensitivity analysis. Differences across treatments in quality-adjusted life years across methods were modest, ranging from 10.3 to

  7. [Multilateral Strategies Utilizing Exosomes for Cancer Therapy].

    Exosomes are nano-sized extracellular vesicles which transfer their components such as RNA, DNA, and proteins from one cell to another cell. The components are released to the cytoplasm of the recipient cells, having an effect on the cells. Cancerderived exosomes promote cancer progression, invasion, gain of drug resistance, and metastasis. Recently, according to their characteristics, it is expected to apply exosomes to cancer therapies, such as utilizing exosomes as drug delivery systems(DDS) for anticancer drugs and as cancer vaccines to enhance immunity to cancer cells. More, as the cancer-derived exosomes have cancer-promoting effects on multiple stages, inhibiting the function of the cancer-derived exosomes would be helpful to cancer therapies by suppressing cancer progression. DDS and cancer vaccines utilizing exosomes are now undergoing clinical studies, although DDS is suffering from loading efficiency. Treatments by inhibiting the functions of cancer-derived exosomes have still only few reports at experimental levels. Recently, we showed in a mouse model that disruption of cancer-derived exosomes by antibodies could suppress lung metastasis of the human breast cancer cells. Exosomes will provide us the multiple strategies to fight with cancer, which can be applied to cancers from many organs. It is important to confirm safety and overcome technical problems to bring exosomes in practical use.

Different endocrine strategies are available for the treatment of hormone-sensitive breast cancer, including antiestrogen tamoxifen and fulvestrant, as well as third-generation aromatase inhibitors (AIs, such as letrozole, anastrozole, and exemestane. In this review, we will focus on exemestane, its clinical use, and its side effects. Exemestane is a steroidal third-generation AI now used in all treatment settings for breast cancer. In the metastatic disease, it has been extensively investigated as the first-, second-, and further-line treatment and it is now registered for the treatment of postmenopausal women with advanced estrogen-receptor-positive breast cancer whose disease has progressed following antiestrogen therapy. A potential lack of cross-resistance with nonsteroidal AIs has been described, giving additional therapeutic opportunities in sequences of endocrine agents. Exemestane is also approved for the adjuvant treatment of postmenopausal early breast cancer, either as upfront monotherapy for 5 years, as a switch following 2–3 years of tamoxifen, or as extended therapy beyond 5 years of adjuvant treatment. New promising data also showed a beneficial effect in young premenopausal early breast cancer patients, when administered together with ovarian suppression. Interesting results have also emerged when exemestane has been investigated as neodjuvant treatment as well as preventive agent in healthy women at high risk for breast cancer. Exemestane is generally well tolerated, with a side effect profile similar to that of other AIs, including menopausal

    Retroperitoneal lymph node dissection (RPLND) for the treatment of testicular cancer is a relatively rare and complex operation that may contribute to differences in utilization. We sought to characterize the use of RPLND between different categories of cancer center facilities in the United States. The National Cancer Database was queried for patients with germ cell tumors treated at different types of cancer centers between 1998 and 2011. The proportion of patients who underwent RPLND was stratified by stage and histology and then compared between treatment facilities. RPLND utilization was then compared between facility types as a function of time. A total of 59,652 patients met inclusion criteria and 5,475 (9.2%) underwent RPLND. The proportion of patients treated with RPLND for non-seminomatous germ cell tumor (NSGCT) was significantly different between cancer center types for all stages (Pcancer centers. There was no difference in the proportion of RPLND utilization for stage II and III seminoma stratified by treatment facility. There was a significantly decreased trend in the utilization of RPLND for stage I (P = 0.032) NSGCT whereas utilization was increased for stage III NSGCT (P≤0.001) over the study period. The proportion of patients undergoing RPLND for NSGCT varies significantly by the type of cancer center and is used most often in academic cancer centers. Utilization of RPLND decreased for stage I NSGCT and increased for stage III NSGCTs during the study period. Copyright © 2016 Elsevier Inc. All rights reserved.

    For more than 50 years, hyperthermia-based cancer researchers have utilized mathematical models, cell culture studies and animal models to better understand, develop and validate potential new treatments. It has been, and remains, unclear how and to what degree these research techniques depend on, complement and, ultimately, translate accurately to a successful clinical treatment. In the past, when mathematical models have not proven accurate in a clinical treatment situation, the initiating quantitative scientists (engineers, mathematicians and physicists) have tended to believe the biomedical parameters provided to them were inaccurately determined or reported. In a similar manner, experienced biomedical scientists often tend to question the value of mathematical models and cell culture results since those data typically lack the level of biologic and medical variability and complexity that are essential to accurately study and predict complex diseases and subsequent treatments. Such quantitative and biomedical interdependence, variability, diversity and promise have never been greater than they are within magnetic nanoparticle hyperthermia cancer treatment. The use of hyperthermia to treat cancer is well studied and has utilized numerous delivery techniques, including microwaves, radio frequency, focused ultrasound, induction heating, infrared radiation, warmed perfusion liquids (combined with chemotherapy), and, recently, metallic nanoparticles (NP) activated by near infrared radiation (NIR) and alternating magnetic field (AMF) based platforms. The goal of this paper is to use proven concepts and current research to address the potential pathobiology, modeling and quantification of the effects of treatment as pertaining to the similarities and differences in energy delivered by known external delivery techniques and iron oxide nanoparticles.

Twenty-one women with arm lymphedema resulting from the surgical and radiotherapeutic treatment of breast cancer were randomly selected. Evaluation was made by water-displacement volumetry before and after each session. The patients were submitted to a series of active exercises using a facilitating device for four 12-minute sessions with intervals of 3 minutes between sessions in the sitting position with alignment of the spinal column. The lymphedematous arm was maintained under compression using a cotton-polyester sleeve. The active exercising device used was a mobile flexion bar fixed on a metal base at a height of 30 cm from the tabletop and at a distance of 10 cm from the patient’s body. The paired t-test was utilized for statistical analysis with an alpha error of 5% (p-value ≤0.05 being considered significant. The initial mean volume of the arms was 2,089.9 and the final volume was 2,023.0 mL with a mean loss of 66.9 mL (p-value <0.001. In conclusion, active exercises utilizing facilitating devices can contribute to a reduction in size of lymphedematous limbs.

    Introduction of prostate cancer screening using PSA leads to a disproportional increase of cancer incidence. Most of those tumors are small and indolent in behavior. When diagnosed, they are usually managed by radical treatment modalities despite the growth of serious adverse events of such therapy. Active surveillance appears to be an alternative treatment approach for the majority of those patients. Author stresses on the particularities of the prostate cancer diagnosed in the PSA era. Show the importance of patient stratification and the utility of the use of nomograms in clinical praxis. The clinical importance of treatment choices based on life expectancy of patient, concomitant diseases on one side and cancer biological behavior in the other side is discussed. Critically discuss the new approach of radiation with proton beams advertising that it remains an experimental therapeutic choice. (author)

    There are two purposes of using combined chemotherapy and radiotherapy in the treatment of cancers. One is to suppress distant metastasis, especially micrometastasis; the other is to improve localized control. As a trial of the utility of the former, systemic chemotherapy with CDDP and 5 FU was given successively with radiotherapy to treat nasopharyngeal cancer. The survival rate was significantly improved compared with historical control cases. The main reason for this effectiveness was the improvement of localized control. The suppression of distant metastasis is the subject of future research. As a trial of the utility of the latter, a super-selective intraarterial chemotherapy with CBDCA combined with radiotherapy was used to head and neck localized progressive cancers. The control of localized cancer was remarkably effective. This treatment is considered to be especially suitable for locally advanced tongue cancer and cancer of the root of the tongue. (author)

    Older women experience a large share of breast cancer incidence and death. With the projected rise in the number of older cancer patients, adjuvant chemo-, radiation and endocrine therapy management will become a key component of breast cancer treatment in older women. Many factors influence adjuvant treatment decisions including patient preferences, life expectancy and tumor biology. Geriatric assessment predicts important outcomes, identifies key deficits, and can aid in the decision making process. This review utilizes clinical vignettes to illustrate core principles in adjuvant management of breast cancer in older women and suggests an approach incorporating life expectancy and geriatric assessment.

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

    Purpose: To determine quality of life (QOL) and health utility in irradiated laryngeal cancer survivors. Materials and Methods: Over 6 months, consecutive follow-up patients at a comprehensive cancer centre completed the QOL questionnaire FACT-H and N and the time trade-off (TTO) utility instrument. Results: Inclusion criteria were met by 339 patients, of whom 269 were eligible, 245 were approached, and 120 agreed to participate. Most participants were men (83%) who had received radiotherapy (97%) for Stage I disease (53%) of the glottis (75%); 7% had undergone total laryngectomy. Participants differed from nonparticipants only in being younger (mean age, 65 vs. 68 years, p = 0.0049) and having higher performance status (Karnofsky 88 vs. 84, p = 0.0012). The average scores for FACT-H and N and the TTO were 124/144 (SD, 14) and 0.90/1.0 (SD, 0.16) respectively. FACT-H and N score was more highly correlated with Karnofsky score (r = 0.43, p = 0.001) than with the TTO (r = 0.29, p = 0.002). Gender predicted QOL (means: M = 125, F 118), while natural speech, no relapses, and more time since initial treatment predicted higher utility. Conclusion: The QOL of irradiated laryngeal cancer survivors was reasonably high and independent of initial disease variables. The QOL questionnaire correlated more strongly with performance status than with utility, suggesting that QOL and utility measures may be perceived differently by patients

    There are limited comparative survival data for prostate cancer (PCa) patients managed with a low-dose rate brachytherapy (LDR-B) boost and dose-escalated external-beam radiotherapy (DE-EBRT) alone. To compare overall survival (OS) for men with unfavorable PCa between LDR-B and DE-EBRT groups. Using the National Cancer Data Base, we identified men with unfavorable PCa treated between 2004 and 2012 with androgen suppression (AS) and either EBRT followed by LDR-B or DE-EBRT (75.6-86.4Gy). Treatment selection was evaluated using logistic regression and annual percentage proportions. OS was analyzed using the Kaplan-Meier method, log-rank test, Cox proportional hazards, and propensity score matching. We identified 25038 men between 2004 and 2012, during which LDR-B boost utilization decreased from 29% to 14%. LDR-B was associated with better OS on univariate (7-yr OS: 82% vs 73%; pLDR-B boost (HR 0.74, 95% CI 0.66-0.89). The OS benefit of LDR-B boost persisted when limited to men aged LDR-B boost utilization declined and was associated with better OS compared to DE-EBRT alone. LDR-B boost is probably the ideal treatment option for men with unfavorable PCa, pending long-term results of randomized trials. We compared radiotherapy utilization and survival for prostate cancer (PCa) patients using a national database. We found that low-dose rate brachytherapy (LDR-B) boost, a method being used less frequently, was associated with better overall survival when compared to dose-escalated external-beam radiotherapy alone for men with unfavorable PCa. Randomized trials are needed to confirm that LDR-B boost is the ideal treatment. Copyright © 2017 European Association of Urology. Published by Elsevier B.V. All rights reserved.

    Full Text Available Madappa N Kundranda, Tomislav Dragovich Division of Hematology and Oncology, Banner MD Anderson Cancer Center, Gilbert, AZ, USA Abstract: Pancreatic ductal adenocarcinoma remains one of the deadliest epithelial cancers, primarily due to late diagnosis, early metastasis and the lack of effective treatments. With recent advances in systemic therapies, the median survival for metastatic disease has essentially doubled to approximately 1 year, and a significant number of patients are receiving multiple lines of therapy. One such first-line therapy is the combination of gemcitabine with nab-paclitaxel, which was approved by the US Food and Drug Administration in 2013. This standard option is now serving as a backbone to other novel combinations. In this review, we focus on the development of this combination, its clinical utility, and real-life experiences of managing patients with metastatic pancreatic ductal adenocarcinoma receiving gemcitabine and nab-paclitaxel.

    More than 50% of breast cancer patients are diagnosed before the age of 65. Returning to work after treatment is, therefore, of interest for both the individual and society. The aim was to study the effect of support group intervention on sick leave and health care utilization in economic terms. Of 382 patients with newly diagnosed breast cancer, 191 + 191 patients were randomized to an intervention group or to a routine control group, respectively. The intervention group received support intervention on a residential basis for one week, followed by four days of follow-up two months later. The support intervention included informative-educational sections, relaxation training, mental visualization and non-verbal communication. Patients answered a questionnaire at baseline, two, six and 12 months about sick leave and health care utilization. There was a trend towards longer sick leave and more health care utilization in the intervention group. The difference in total costs was statistically significantly higher in the intervention group after 12 months (p = 0.0036). Costs to society were not reduced with intervention in its present form.

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

    Full Text Available Abstract Introduction Indigenous Australians experience more aggressive cancers and higher cancer mortality rates than other Australians. Cancer patients undergoing treatment are likely to access health services (e.g. social worker, cancer helpline, pain management services. To date Indigenous cancer patients’ use of these services is limited. This paper describes the use of health services by Indigenous cancer patients. Methods Indigenous cancer patients receiving treatment were recruited at four major Queensland public hospitals (Royal Brisbane Women’s Hospital, Princess Alexandra, Cairns Base Hospital and Townsville Hospital. Participants were invited to complete a structured questionnaire during a face-to-face interview which sought information about their use of community and allied health services. Results Of the 157 patients interviewed most were women (54.1%, of Aboriginal descent (73.9%, lived outer regional areas (40.1% and had a mean age of 52.2 years. The most frequent cancer types were breast cancer (22.3%, blood related (14.0%, lung (12.1% and gastroenterological (10.8%. More than half of the participants reported using at least one of the ‘Indigenous Health Worker/Services’ (76.4%, ‘Allied Health Workers/Services’ (72.6% and ‘Information Sources’ (70.7%. Younger participants 19–39 years were more likely to use information sources (81.0% than older participants who more commonly used community services (48.8%. The cancer patients used a median of three health services groups while receiving cancer treatment. Conclusions Indigenous cancer patients used a range of health services whilst receiving treatment. Indigenous Health Workers/Services and Allied Health Workers/Services were the most commonly used services. However, there is a need for further systematic investigation into the health service utilization by Indigenous cancer patients.

    To assess the frequency of biopsies and molecular diagnostic testing (human DNA/RNA analysis), anti-cancer drug use (genomically-matched targeted therapy [GMTT], unmatched targeted therapy [UTT], endocrine therapy [ET], and chemotherapy [CT]), and medical service costs among adults with metastatic cancer. Adults diagnosed with metastatic breast, non-small cell lung (NSCLC), colorectal, head and neck, ovarian, and uterine cancer (2010Q1-2015Q1) were identified in the OptumHealth Care Solutions claims database and followed from first metastatic diagnosis for ≥1 month and until the end of data availability. Utilization was assessed for each cancer cohort (all and patients aged ≥65 years); per-patient-per-month (PPPM) medical service costs were assessed for all patients. Testing frequency estimates were applied to Surveillance, Epidemiology, and End Results Program data to estimate the number of untested patients (2010-2014). Patients with metastatic cancer (n = 8,193; breast [n = 3,414], NSCLC [n = 2,231], colorectal [n = 1,611], head and neck [n = 511], ovarian [n = 275], and uterine [n = 151]) were 63 years old (mean), with 11.1-22.2 months of observation. Biopsy and molecular diagnostic testing frequencies ranged from 7% (uterine) to 73% (ovarian), and from 34% (head and neck) to 52% (breast), respectively. Few were treated with GMTT (breast, 11%; NSCLC, 9%; colorectal, 6%). Treatment with UTT ranged from 0.7% (uterine) to 21% (colorectal). Biopsy, diagnostic testing, and anti-cancer drug therapy were less frequent for those ≥65 years. Medical service costs (PPPM, mean) ranged from $6,618 (head and neck) to $9,940 (ovarian). The estimated number of untested new patients with metastatic cancer was 636,369 (all) and 341,397 (≥65). In addition to the limitations of claims analyses, diagnostic testing frequency may be under-estimated if patients underwent testing prior to study inclusion. The low frequency of molecular diagnostic

    Full Text Available Purpose : Several prior studies have suggested that brachytherapy utilization has markedly decreased, coinciding with the recent increased utilization of intensity modulated radiation therapy, as well as an increase in urologist-owned centers. We sought to investigate the brachytherapy utilization in a large, hospital-based registry. Material and methods: Men with prostate cancer diagnosed between 2004-2012 and treated with either external beam radiation and/or prostate brachytherapy were abstracted from the National Cancer Database. In order to be included, men had to be clinically staged as T1c-T2aNx-0Mx-0, Gleason 6, PSA ≤ 10.0 ng/ml. Descriptive statistics were used to analyze brachytherapy utilization over time and were compared via χ2. Multivariate logistic regression was used to assess for covariables associated with increased brachytherapy usage. Results : There were 89,413 men included in this study, of which 37,054 (41.6% received only external beam radiation, and 52,089 (58.4% received prostate brachytherapy. The use of brachytherapy declined over time from 62.9% in 2004 to 51.3% in 2012 (p < 0.001. This decline was noted in both academic facilities (60.8% in 2004 to 47.0% in 2012, p < 0.001 as well as in non-academic facilities (63.7% in 2004 to 53.0% in 2012, p < 0.001. The decline was more pronounced in patients who lived closer to treatment facilities than those who lived further. The use of intensity modulated radiation therapy increased during this same time period from 18.4% in 2004 to 38.2% in 2012 (p < 0.001. On multivariate analysis, treatment at an academic center, increasing age, decreasing distance from the treatment center, and years of diagnosis from 2006-2012 were significantly associated with reduced brachytherapy usage. Conclusions : In this hospital-based registry, prostate brachytherapy usage has declined for low risk prostate cancer as intensity modulated radiation therapy usage has increased. However, it still

    Past examinations of breast cancer treatment barriers have typically included registry, claims-based, and smaller survey studies. We examined treatment barriers using a novel, comprehensive, social media analysis of online, candid discussions about breast cancer. Using an innovative toolset to search postings on social networks, message boards, patient communities, and topical sites, we performed a large-scale qualitative analysis. We examined the sentiments and barriers expressed about breast cancer treatments by Internet users during 1 year (2/1/14-1/31/15). We categorized posts based on thematic patterns and examined trends in discussions by race/ethnicity (white/black/Hispanic) when this information was available. We identified 1,024,041 unique posts related to breast cancer treatment. Overall, 57 % of posts expressed negative sentiments. Using machine learning software, we assigned treatment barriers for 387,238 posts (38 %). Barriers included emotional (23 % of posts), preferences and spiritual/religious beliefs (21 %), physical (18 %), resource (15 %), healthcare perceptions (9 %), treatment processes/duration (7 %), and relationships (7 %). Black and Hispanic (vs. white) users more frequently reported barriers related to healthcare perceptions, beliefs, and pre-diagnosis/diagnosis organizational challenges and fewer emotional barriers. Using a novel analysis of diverse social media users, we observed numerous breast cancer treatment barriers that differed by race/ethnicity. Social media is a powerful tool, allowing use of real-world data for qualitative research, capitalizing on the rich discussions occurring spontaneously online. Future research should focus on how to further employ and learn from this type of social intelligence research across all medical disciplines.

    The Göteborg randomised population-based prostate cancer screening trial demonstrated that prostate-specific antigen (PSA)-based screening reduces prostate cancer deaths compared with an age-matched control group. Utilising the prostate cancer detection rates from this study, we investigated the clinical and cost effectiveness of a similar PSA-based screening strategy for an Australian population of men aged 50-69 years. A decision model that incorporated Markov processes was developed from a health system perspective. The base-case scenario compared a population-based screening programme with current opportunistic screening practices. Costs, utility values, treatment patterns and background mortality rates were derived from Australian data. All costs were adjusted to reflect July 2015 Australian dollars (A$). An alternative scenario compared systematic with opportunistic screening but with optimisation of active surveillance (AS) uptake in both groups. A discount rate of 5 % for costs and benefits was utilised. Univariate and probabilistic sensitivity analyses were performed to assess the effect of variable uncertainty on model outcomes. Our model very closely replicated the number of deaths from both prostate cancer and background mortality in the Göteborg study. The incremental cost per quality-adjusted life-year (QALY) for PSA screening was A$147,528. However, for years of life gained (LYGs), PSA-based screening (A$45,890/LYG) appeared more favourable. Our alternative scenario with optimised AS improved cost utility to A$45,881/QALY, with screening becoming cost effective at a 92 % AS uptake rate. Both modelled scenarios were most sensitive to the utility of patients before and after intervention, and the discount rate used. PSA-based screening is not cost effective compared with Australia's assumed willingness-to-pay threshold of A$50,000/QALY. It appears more cost effective if LYGs are used as the relevant outcome, and is more cost effective than the

    The use of accepted prostate cancer risk stratification groups based on prostate-specific antigen, T stage and Gleason score assists in therapeutic treatment decision-making, clinical trial design and outcome reporting. The utility of integrating novel prognostic factors into an updated risk stratification schema is an area of current debate. The purpose of this work is to critically review the available literature on novel pre-treatment prognostic factors and alternative prostate cancer risk stratification schema to assess the feasibility and need for changes to existing risk stratification systems. A systematic literature search was conducted to identify original research publications and review articles on prognostic factors and risk stratification in prostate cancer. Search terms included risk stratification, risk assessment, prostate cancer or neoplasms, and prognostic factors. Abstracted information was assessed to draw conclusions regarding the potential utility of changes to existing risk stratification schema. The critical review identified three specific clinically relevant potential changes to the most commonly used three-group risk stratification system: (1) the creation of a very-low risk category; (2) the splitting of intermediate-risk into a low- and high-intermediate risk groups; and (3) the clarification of the interface between intermediate- and high-risk disease. Novel pathological factors regarding high-grade cancer, subtypes of Gleason score 7 and percentage biopsy cores positive were also identified as potentially important risk-stratification factors. Multiple studies of prognostic factors have been performed to create currently utilized prostate cancer risk stratification systems. We propose potential changes to existing systems.

    The United States Preventive Services Task Force (USPSTF) has recommended against testicular self-examinations (TSE) or clinical examination for testicular cancer screening. However, in this recommendation there was no consideration of the significant fiscal cost of treating advanced disease versus evaluation of benign disease. In this study, a cost-utility validation for TSE was performed. The cost of treatment for an advanced-stage testicular tumor (both seminomatous and nonseminomatous) was compared to the cost of six other scenarios involving the clinical assessment of a testicular mass felt during self-examination (four benign and two early-stage malignant). Medicare reimbursements were used as an estimate for a national cost standard. The total treatment cost for an advanced-stage seminoma ($48,877) or nonseminoma ($51,592) equaled the cost of 313-330 benign office visits ($156); 180-190 office visits with scrotal ultrasound ($272); 79-83 office visits with serial scrotal ultrasounds and labs ($621); 6-7 office visits resulting in radical inguinal orchiectomy for benign pathology ($7,686) or 2-3 office visits resulting in treatment and surveillance of an early-stage testicular cancer ($17,283: seminoma, $26,190: nonseminoma). A large number of clinical evaluations based on the TSE for benign disease can be made compared to the cost of one missed advanced-stage tumor. An average of 2.4 to 1 cost benefit ratio was demonstrated for early detected testicular cancer versus advanced-stage disease. © 2014 The Authors. Cancer Medicine published by John Wiley & Sons Ltd.

    Recently published articles have established that a substantial number of cancer patients utilize the Internet to gather information about their respective diagnoses. The challenges for medical providers include understanding the prevalence and characteristics of patients using the Internet, reasons for Internet use, and the effectiveness of currently available websites in providing useful health-related information to patients. Adults with cancer were asked to complete a self-administered, anonymous, 21-item questionnaire upon registration at the Alvin J. Siteman Cancer Center at the Washington University School of Medicine. There were 500 respondents (mean age 58 years (range 18-90), 83% Caucasian and 15% African-American). Three hundred ninety-eight participants (80%) reported access to the Internet, and 315 (63%) reported searching for information about cancer on the Internet. Patients accessing the Internet for cancer information were younger than those who did not (median age 56 vs. 63 years; p Internet usage for cancer information also differed by race (p Internet for cancer information, 13.3% of patients had their decisions towards treatments affected or changed, and 11.4% of patients had their choice in physicians affected or changed because of Internet use; 23.5% of patients sought information on clinical trials, and 9.5% of patients were influenced or changed their decision regarding clinical trial enrollment due to Internet information. Approximately two thirds of patients with cancer used the Internet to obtain information about their disease. Factors affecting Internet use for cancer information included age, race, and education.

    Patients with cancer frequently experience unintended weight loss due to gastrointestinal (GI) dysfunction caused by the malignancy or treatment of the malignancy. However, others may present with weight loss related to other symptoms not clearly associated with identifiable GI dysfunction such as anorexia and early satiety. Cancer cachexia (CC) is a multifactorial syndrome that is generally characterized by ongoing loss of skeletal muscle mass with or without fat loss, often accompanied by anorexia, weakness, and fatigue. CC is associated with poor tolerance of antitumor treatments, reduced quality of life (QOL), and negative impact on survival. Symptoms associated with CC are thought to be caused in part by tumor-induced changes in host metabolism that result in systemic inflammation and abnormal neurohormonal responses. Unfortunately, there is no single standard treatment for CC. Nutrition consequences of oncologic treatments should be identified early with nutrition screening and assessment. Pharmacologic agents directed at improving appetite and countering metabolic abnormalities that cause inefficient nutrient utilization are currently the foundation for treating CC. Multiple agents have been investigated for their effects on weight, muscle wasting, and QOL. However, few are commercially available for use. Considerations for choosing the most appropriate treatment include effect on appetite, weight, QOL, risk of adverse effects, and cost and availability of the agent.

    Full Text Available There are no universally approved re-vaccination guidelines for non-transplant pediatric cancer survivors. We hypothesized that by utilizing a response-based re-vaccination schedule, we could tailor vaccine schedules in off-treatment cancer survivors. Pre-vaccination antibody levels were obtained in 7 patients at an average of 20 days after the end of treatment date. In those without protective antibody levels, we administered vaccines 3 months after completion of treatment. Revaccinating patients 3 months after the end of treatment date resulted in protective antibody levels for most vaccines. We showed, on a preliminary basis, that vaccinating non-transplanted pediatric cancer survivors can be dynamically implemented in children with recovering immune function.

    Advances in medical technology are changing surgical standards for colon cancer treatment. The laparoscopic colectomy is equivalent to the standard open colectomy while providing additional benefits. It is currently unknown what factors influence utilization of laparoscopic surgery in rural areas and if treatment disparities exist. The objectives of this study were to examine demographic and clinical characteristics associated with receiving laparoscopic colectomy and to examine the differences between rural and urban patients who received either procedure. This study utilized a linked data set of Nebraska Cancer Registry and hospital discharge data on colon cancer patients diagnosed and treated in the entire state of Nebraska from 2008 to 2011 (N = 1,062). Multiple logistic regression analysis was performed to identify predictors of receiving the laparoscopic treatment. Rural colon cancer patients were 40% less likely to receive laparoscopic colectomy compared to urban patients. Independent predictors of receiving laparoscopic colectomy were younger age (colon cancer and important disparities exist for rural cancer patients in accessing the specialized treatment. As cancer treatment becomes more specialized, the importance of training and placement of general surgeons in rural communities must be a priority for health care planning and professional training institutions. © 2015 National Rural Health Association.

    Two therapies are appropriate as 2nd-line treatment of non-small cell lung cancer (NSCLC) patients: chemotherapy and epidermal growth factor receptor (EGFR) inhibitor therapy. VeriStrat, a serum proteomic test, can be used to guide treatment decisions for NSCLC patients. The test classifies patients as likely to benefit from either of these two treatment options. The objective of this research was to model the anticipated survival and cost-effectiveness of four different treatment strategies: chemotherapy for all patients (C-all), EGFR inhibitor for all (E-all), a performance status guided selection strategy (PS-guided), and a strategy guided by VeriStrat test results (V-guided). We developed a Markov model with the perspective of the U.S. health care system. Model inputs were taken from published literature for the base-case analysis. One-way and probabilistic sensitivity analyses were performed. The C-all treatment strategy showed the best overall survival outcome (10.1 months), followed by V-guided (9.6 months), PS-guided (9.2 months), and E-all (8.2 months) strategies. The incremental cost-effectiveness ratio (ICER) of a V-guided treatment strategy was $91,111 (vs. E-all) and $8462 (vs. PS-guided) per quality-adjusted life year (QALY). The ICER for C-all compared to V-guided was $105,616. This cost-utility analysis indicates that a treatment strategy guided by the VeriStrat test in patients receiving second-line therapy for NSCLC may experience an overall survival benefit at an incremental cost-effectiveness ratio that is reasonable when compared with other practices, including cancer treatments, generally covered in the U.S. health care system. However, treating all patients with chemotherapy yielded the greatest expected survival. Copyright © 2013. Published by Elsevier Ireland Ltd.

    Full Text Available Several drugs have been approved for treatment of multiple sclerosis. Dimethyl fumarate (DMF is utilized as an oral drug to treat this disease and is proven to be potent with less side effects than several other drugs. On the other hand, monomethyl fumarate (MMF, a related compound has not been examined in greater details although it has the potential as a therapeutic drug for multiple sclerosis and other diseases. The mechanism of action of DMF or MMF is related to their ability to enhance the antioxidant pathways and to inhibit reactive oxygen species. However, other mechanisms have also been described which include effects on monocytes, dendritic cells, T cells, and natural killer cells. It is also reported that DMF might be useful for treating psoriasis, asthma, aggressive breast cancers, hematopoeitic tumors, inflammatory bowel disease, intracerebral hemorrhage, osteoarthritis, chronic pancreatitis, and retinal ischemia. In this article we will touch on some of these diseases with an emphasis on the effects of DMF and MMF on various immune cells.

    This study aimed to estimate utility values in laypeople and productivity loss for women with breast cancer in Sweden and the Netherlands. To capture utilities, validated health state vignettes were used, which were translated into Dutch and Swedish. They described progressive disease, stable disease, and 7 grade 3/4 adverse events. One hundred members of the general public in each country rated the states using the visual analog scale and time trade-off method. To assess productivity, women who had recently completed or were currently receiving treatment for early or advanced breast cancer (the Netherlands, n = 161; Sweden, n = 52) completed the Work Productivity and Activity Impairment-General Health (WPAI-GH) questionnaire. Data were analyzed using means (SD). The utility study showed that the Swedish sample rated progressive and stable disease (mean, 0.61 [0.07] and 0.81 [0.05], respectively) higher than did the Dutch sample (0.49 [0.06] and 0.69 [0.05]). The health states incorporating the toxicities in both countries produced similar mean scores. Results of the WPAI-GH showed that those currently receiving treatment reported productivity reductions of 69% (the Netherlands) and 72% (Sweden); those who had recently completed therapy reported reductions of 41% (the Netherlands) and 40% (Sweden). The differences in the utility scores between the 2 countries underline the importance of capturing country-specific values. The significant impact of adverse events on health-related quality of life was also highlighted. The WPAI-GH results demonstrated how the negative impact of breast cancer on productivity persists after women have completed their treatment. Copyright © 2013 Elsevier HS Journals, Inc.

    The Ministry of Public Health (MOPH) in Lebanon provides cancer drugs free of charge for uninsured patients who account for more than half the total caseload. Other categories of cancer care are subsidized under more stringent eligibility criteria. MOPH's large database offers an excellent opportunity to analyze the cost of cancer treatment in Lebanon. Using utilization and spending data accumulated at MOPH during 20082013, the cost to the public budget of cancer drugs was assessed per case and per drug type. The average annual cost of cancer drugs was 6,475$ per patient. Total cancer drug costs were highest for breast cancer, followed by chronic myeloid leukemia (CML), colorectal cancer, lung cancer, and NonHodgkin's lymphoma (NHL), which together represented 74% of total MOPH cancer drug expenditure. The annual average cancer drug cost per case was highest for CML ($31,037), followed by NHL ($11,566). Trastuzumab represented 26% and Imatinib 15% of total MOPH cancer drug expenditure over six years. Sustained increase in cancer drug cost threatens the sustainability of MOPH coverage, so crucial for socially vulnerable citizens. To enhance the bargaining position with pharmaceutical firms for drug cost containment in a small market like Lebanon, drug price comparisons with neighboring countries which have already obtained lower prices may succeed in lowering drug costs.

Chi-square tests and one-way analyses of variance were utilized to assess differences between cancer survivors and non-cancer controls in behavioral characteristics, symptoms and functions, preventative screenings, and health care costs.Results: Hematologic malignancies, melanoma, and breast, prostate, lung, colon/rectal, bladder, kidney/renal, uterine, thyroid, and pancreatic cancers had the highest incidence rates. Breast cancer had the highest incidence among women (156.4 per 100,000 and prostate cancer among men (167.2 per 100,000. The presence of pain (P=0.0003, fatigue (P=0.0005, and sadness (P=0.0012 was consistently higher in cancer survivors 40–64 years old vs. non-cancer controls. Cancer survivors ≥65 years old had higher rates of any functional limitations (P=0.0039 and reported a lack of exercise (P<0.0001 compared with the non-cancer controls. However, obesity rates were similar between cancer survivors and non-cancer controls. Among cancer survivors, an estimated 13.5 million spent $169.4 billion a year on treatment, with the highest direct expenditures for breast cancer ($39 billion, prostate cancer ($37 billion, and hematologic malignancies ($25 billion. Prescription medications and office-based visits contributed equally as the cost drivers of direct medical spending for breast cancer, while inpatient hospitalization was the driver for prostate (52.8% and lung (38.6% cancers

    Purpose: To determine the trends in brachytherapy use in cervical cancer in the United States and to identify factors and survival benefits associated with brachytherapy treatment. Methods and Materials: Using the Surveillance, Epidemiology, and End Results (SEER) database, we identified 7359 patients with stages IB2-IVA cervical cancer treated with external beam radiation therapy (EBRT) between 1988 and 2009. Propensity score matching was used to adjust for differences between patients who received brachytherapy and those who did not from 2000 onward (after the National Cancer Institute alert recommending concurrent chemotherapy). Results: Sixty-three percent of the 7359 women received brachytherapy in combination with EBRT, and 37% received EBRT alone. The brachytherapy utilization rate has decreased from 83% in 1988 to 58% in 2009 (P<.001), with a sharp decline of 23% in 2003 to 43%. Factors associated with higher odds of brachytherapy use include younger age, married (vs single) patients, earlier years of diagnosis, earlier stage and certain SEER regions. In the propensity score-matched cohort, brachytherapy treatment was associated with higher 4-year cause-specific survival (CSS; 64.3% vs 51.5%, P<.001) and overall survival (OS; 58.2% vs 46.2%, P<.001). Brachytherapy treatment was independently associated with better CSS (hazard ratio [HR], 0.64; 95% confidence interval [CI], 0.57-0.71), and OS (HR 0.66; 95% CI, 0.60 to 0.74). Conclusions: This population-based analysis reveals a concerning decline in brachytherapy utilization and significant geographic disparities in the delivery of brachytherapy in the United States. Brachytherapy use is independently associated with significantly higher CSS and OS and should be implemented in all feasible cases.

    2017-03-01

    Interest in precision diagnostics has been fuelled by the concept that early detection of cancer would benefit patients; that is, if detected early, more tumours should be resectable and treatment more efficacious. Serum contains massive amounts of potentially diagnostic information, and affinity proteomics has risen as an accurate approach to decipher this, to generate actionable information that should result in more precise and evidence-based options to manage cancer. To achieve this, we need to move from single to multiplex biomarkers, a so-called signature, that can provide significantly increased diagnostic accuracy. This Opinion article focuses on the progress being made in identifying protein biomarker signatures of clinical utility, using blood-based proteomics.

    Full Text Available Abstract Background Increased health care costs have made it incumbent on health-care facilities and physicians to demonstrate both clinical and cost efficacy when recommending treatments. Though studies have examined the cost-effectiveness of adjuvant goserelin with radiotherapy for locally advanced prostate cancer, few have compared the cost-effectiveness of adjuvant goserelin to adjuvant chemotherapy alone in premenopausal breast cancer. Methods In this retrospective study at one hospital, the records of 152 patients with stage Ia to IIIa ER + breast cancer who received goserelin or chemotherapy were reviewed. Survival analysis was assessed by the Kaplan-Meier method. Patients were interviewed to evaluate their quality of life using the European Organization for Research and Treatment Quality of Life questionnaire (EORTC-QLQ-C30, version 4.0, and to obtain the utility value by the standard gamble (SG and visual scale (VS methods. Total medical cost was assessed from the (National Health Insurance NHI payer's perspective. Results Survival at 11 years was significantly better in the groserelin group (P Conclusions Goserelin therapy results in better survival and higher utility-weighted life-years, and is more cost-effective than TC or TEC chemotherapy.

    With the expected rise in newly diagnosed cancer cases among the elderly in Singapore, the affordability of cancer treatments, particularly of targeted therapies, will be a growing concern for patients. This study examines the perspectives of aging cancer patients on the financial burden of their cancer treatments. A single-center, prospective study was conducted in the largest ambulatory cancer center in Singapore. Older (50 years old and above) cancer patients receiving treatment were recruited. Patients completed three sets of self-reporting tools assessing their (a) demographics and lifestyles, (b) health-related quality of life, and (c) perceptions of cancer treatment costs. The association between targeted therapy utilities and their perceived financial burden was evaluated using a multivariable logistic regression. Five hundred and sixteen patients were included in the study. The majority of the respondents (69.6 %) were between 50 and 64 years old. The majority were Singaporeans (97.7 %), belonged to the ethnic Chinese group (88.4 %), and most were female (59.1 %). The users of targeted therapies were 2.92 times more likely to perceive that the amount of cash that they spent on cancer treatment was more than expected and 2.52 times more likely to have difficulty paying for cancer treatments. Fortunately, the majority of the respondents (70.6 %) found their existing financial schemes helpful in reducing the necessary out-of-pocket expenses. Although aging cancer patients feel that the financial schemes in Singapore have helped them tremendously, the general perception is that they require further help to offset their out-of-pocket expenses. This is especially true for users of targeted therapies and those who have a poorer health status.

    The utility of adjuvant chemotherapy is clearly demonstrated because she significantly improved relapse and mortality. Globally, we report a one-third breast cancer mortality reduction. Nevertheless, the absolute or individual benefit is uncertain and the final decision depends on benefit-risk balance, integrating tumor biologic characteristics and comorbidities. The most effective regimen must contain an anthracycline and a taxane. This regimen must be proposed if chemotherapy indication is considered: this concerns the majority of triple-negative and HER2-positive cancer For hormone-receptor-positive and HER2-negative breast cancer, the decision of adjuvant or not (in addition to hormonal therapy) is most difficult, particularly for grade 2 tumors. The trastuzumab is an essential treatment for HER2-positive breast cancer, because this tailored therapy has considerably improved the prognosis.

    2014-11-01

    Full Text Available A new problem has emerged with the ever-increasing number of breast cancer survivors. While early screening and advances in treatment have allowed these patients to overcome their cancer, these treatments often have adverse cardiovascular side effects that can produce abnormal cardiovascular function. Chemotherapeutic and radiation therapy have both been linked to cardiotoxicity; these therapeutics can cause a loss of cardiac muscle and deterioration of vascular structure that can eventually lead to heart failure (HF. This cardiomyocyte toxicity can leave the breast cancer survivor with a probable diagnosis of dilated or restrictive cardiomyopathy (DCM or RCM. While current HF standard of care can alleviate symptoms, other than heart transplantation, there is no therapy that replaces cardiac myocytes that are killed during cancer therapies. There is a need to develop novel therapeutics that can either prevent or reverse the cardiac injury caused by cancer therapeutics. These new therapeutics should promote the regeneration of lost or deteriorating myocardium. Over the last several decades the therapeutic potential of cell-based therapy has been investigated for HF patients. In this review we discuss the progress of preclinical and clinical stem cell research for the diseased heart and discuss the possibility of utilizing these novel therapies to combat cardiotoxicity observed in breast cancer survivors.

    Breast cancer is one kind of multi-gene related malignancy.Overexpression of some oncogenes such as HER-2(c-erbB-2,Neu),bcl-2/bcl-xL,protein kinase A(PKA),and transferrin receptor gene(TfR gene),etc significantly affect the prognosis of breast cancer.It was shown that specific suppression of the overexpressed genes above resulted in the improvement of the therapy of breast cancer.Antisense interference.one of useful tools for inhibiting the overexpression of specific oncogenes,was involved in the therapy of breast cancer in recent years. Data indicated that antisense oligonucleotides(ON)could inhibit specially the expression of the target genes on mRNA or protein levels in most of cases;some ON candidates showed encouraging therapeutic effects in vitro and in vivo on breast cancer cell lines or xenografts.Furthermore,the combination use of the antisense ON and normal chemotherapeutic agents indicated synergistic antitumor effects,which was probably the best utilization of antisense ON in the treatment of breast cancer.

    In this short communication we present a re-analysis of homeopathic patient data in comparison to control patient data from the same Outpatient´s Unit "Homeopathy in malignant diseases" of the Medical University of Vienna. In this analysis we took account of a probable immortal time bias. For patients suffering from advanced stages of cancer and surviving the first 6 or 12 months after diagnosis, respectively, the results show that utilizing homeopathy gives a statistically significant (p<0.001) advantage over control patients regarding survival time. In conclusion, bearing in mind all limitations, the results of this retrospective study suggest that patients with advanced stages of cancer might benefit from additional homeopathic treatment until a survival time of up to 12 months after diagnosis.

    Our objective was to evaluate the impact of preoperative axillary ultrasound and core needle biopsy (CNB) on breast cancer treatment decision making. A secondary aim was to evaluate the impact on the utility of intraoperative sentinel lymph node (SLN) frozen section. A review of 84 patients with clinically negative axilla who underwent axillary ultrasound was performed. Sensitivity, specificity, and positive/negative predictive value for axillary ultrasound with CNB was calculated. Thirty-one (37%) had suspicious nodes. Of 27 amenable to CNB, 12 (14%) were malignant, changing treatment plans. The sensitivity of ultrasound and CNB was 54% and specificity 100%; the positive and negative predictive values were 100% and 80%, respectively. In 41 patients with normal ultrasounds who underwent SLN frozen section, 10 (24%) were positive. Preoperative axillary ultrasound impacts treatment decision making in 14%. With a sensitivity of 54%, it is a useful adjunct to, but not replacement for, SLN biopsy. Frozen section remains of utility even after a negative axillary ultrasound. Copyright © 2012 Elsevier Inc.

    Chemotherapy is the preferred treatment regimen for advanced lung cancer patients. This study investigated the health resources utilized by and medical expenses of patients with non-small cell lung cancer (NSCLC) as well as the influence of various chemotherapy regimens on the final medical costs in China. The aim of this study was to provide physicians with a reference to use as the basis for their choice of treatment. Data were collected from the Shanghai Chest Hospital's medical charts and billing database. The collected patient information included the baseline characteristics, medical history, chemotherapy regimens, and medical costs, which were used to estimate the health resources utilized by patients and the cost of treatment. This study included 328 patients, and the average total medical cost was $US14,165. This cost included drugs, which accounted for as much as 78.91% of the total cost, and chemotherapy drugs, which accounted for 51.58% of total drug expenses. The most frequently utilized chemotherapy drug was carboplatin, and the most expensive chemotherapy drug was erlotinib. In drug combinations, gemcitabine was utilized most frequently, the combination of gemcitabine and paclitaxel was the most expensive, and cisplatin was the least expensive drug. Epidermal growth factor receptor-positive patients were treated with targeted drug therapy (icotinib, erlotinib, and gefitinib). The use of recombinant human endostatin was often combined with a vinorelbine plus cisplatin regimen. Traditional Chinese medicines were the most frequently utilized non-chemotherapy drugs, and these drugs were also the most expensive. The final cost significantly depended on the specific chemotherapy regimen; thus, the rationale and cost of the chemotherapy regimen and adjuvant chemotherapy should be considered in patients with advanced NSCLC.

    2012-01-01

    Purpose: This study examines the management and outcomes of muscle-invasive bladder cancer in the United States. Methods and Materials: Patients with muscle-invasive bladder cancer diagnosed between 1988 and 2006 were identified in the Surveillance, Epidemiology, and End Results (SEER) database. Patients were classified according to three mutually exclusive treatment categories based on the primary initial treatment: no local management, radiotherapy, or surgery. Overall survival was assessed with Kaplan-Meier analysis and Cox models based on multiple factors including treatment utilization patterns. Results: The study population consisted of 26,851 patients. Age, sex, race, tumor grade, histology, and geographic location were associated with differences in treatment (all p < 0.01). Patients receiving definitive radiotherapy tended to be older and have less differentiated tumors than patients undergoing surgery (RT, median age 78 years old and 90.6% grade 3/4 tumors; surgery, median age 71 years old and 77.1% grade 3/4 tumors). No large shifts in treatment were seen over time, with most patients managed with surgical resection (86.3% for overall study population). Significant survival differences were observed according to initial treatment: median survival, 14 months with no definitive local treatment; 17 months with radiotherapy; and 43 months for surgery. On multivariate analysis, differences in local utilization rates of definitive radiotherapy did not demonstrate a significant effect on overall survival (hazard ratio, 1.002; 95% confidence interval, 0.999–1.005). Conclusions: Multiple factors influence the initial treatment strategy for muscle-invasive bladder cancer, but definitive radiotherapy continues to be used infrequently. Although patients who undergo surgery fare better, a multivariable model that accounted for patient and tumor characteristics found no survival detriment to the utilization of definitive radiotherapy. These results support continued

There is currently a lack of research for some disease phases including recurrent and metastatic cancer, and treatment-related complications. In selecting HSUVs for cost-effectiveness modeling purposes, preference should be given to EQ-5D utility values; however, mapping to EQ-5D is a potentially valuable technique that should be further developed in this cancer population.

    There is momentum internationally to improve coordination of complex care pathways. Robust evaluations of such interventions are scarce. This paper evaluates the cost-utility of cancer care coordinators for stage III colon cancer patients, who generally require surgery followed by chemotherapy. We compared a hospital-based nurse cancer care coordinator (CCC) with 'business-as-usual' (no dedicated coordination service) in stage III colon cancer patients in New Zealand. A discrete event microsimulation model was constructed to estimate quality-adjusted life-years (QALYs) and costs from a health system perspective. We used New Zealand data on colon cancer incidence, survival, and mortality as baseline input parameters for the model. We specified intervention input parameters using available literature and expert estimates. For example, that a CCC would improve the coverage of chemotherapy by 33% (ranging from 9 to 65%), reduce the time to surgery by 20% (3 to 48%), reduce the time to chemotherapy by 20% (3 to 48%), and reduce patient anxiety (reduction in disability weight of 33%, ranging from 0 to 55%). Much of the direct cost of a nurse CCC was balanced by savings in business-as-usual care coordination. Much of the health gain was through increased coverage of chemotherapy with a CCC (especially older patients), and reduced time to chemotherapy. Compared to 'business-as-usual', the cost per QALY of the CCC programme was $NZ 18,900 (≈ $US 15,600; 95% UI: $NZ 13,400 to 24,600). By age, the CCC intervention was more cost-effective for colon cancer patients costs, meaning the cost-effectiveness was roughly comparable between ethnic groups. Such a nurse-led CCC intervention in New Zealand has acceptable cost-effectiveness for stage III colon cancer, meaning it probably merits funding. Each CCC programme will differ in its likely health gains and costs, making generalisation from this evaluation to other CCC interventions difficult. However, this evaluation suggests

    In many countries of the developed world, there is an increasing trend toward delay in childbearing from 30 to 40 years of age for various reasons. This is unfortunately concordant with an increasing incidence of breast cancer in women who have not yet completed their family. The current choice for premenopausal women with breast cancer is adjuvant therapy which includes cytotoxic chemotherapy, ovarian ablation (by surgery, irradiation, or chemical ovarian suppression), anti-estrogen therapy, or any combination of these. Although the use of adjuvant therapies with cytotoxic drugs can significantly reduce mortality, it raises issues of the long-term toxicity, such as induction of an early menopause and fertility impairment. The risk of infertility is a potential hardship to be faced by the patients following treatment of breast cancer. The offspring of patients who became pregnant after completion of chemotherapy have shown no adverse effects and congenital anomalies from the treatment, but sometimes high rates of abortion (29%) and premature deliveries with low birth weight (40%) have been demonstrated. Therefore, the issue of recent cytotoxic treatment remains controversial and further research is required to define a "safety period" between cessation of treatment and pregnancy. Preservation of fertility in breast cancer survivors of reproductive age has become an important issue regarding the quality of life. Currently, there are several potential options, including all available assisted technologies, such as in vitro fertilization and embryo transfer, in vitro maturation, oocyte and embryo cryopreservation, and cryopreservation of ovarian tissue. Because increased estrogen levels are thought to be potentially risky in breast cancer patients, recently developed ovarian stimulation protocols with the aromatase inhibitor letrozole and tamoxifen appear to provide safe stimulation with endogenous estrogen. Embryo cryopreservation seems to be the most established

    It is estimated that millions of North Americans would qualify for lung cancer screening and that billions of dollars of national health expenditures would be required to support population-based computed tomography lung cancer screening programs. The decision to implement such programs should be informed by data on resource utilization and costs. Resource utilization data were collected prospectively from 2059 participants in the Pan-Canadian Early Detection of Lung Cancer Study using low-dose computed tomography (LDCT). Participants who had 2% or greater lung cancer risk over 3 years using a risk prediction tool were recruited from seven major cities across Canada. A cost analysis was conducted from the Canadian public payer's perspective for resources that were used for the screening and treatment of lung cancer in the initial years of the study. The average per-person cost for screening individuals with LDCT was $453 (95% confidence interval [CI], $400-$505) for the initial 18-months of screening following a baseline scan. The screening costs were highly dependent on the detected lung nodule size, presence of cancer, screening intervention, and the screening center. The mean per-person cost of treating lung cancer with curative surgery was $33,344 (95% CI, $31,553-$34,935) over 2 years. This was lower than the cost of treating advanced-stage lung cancer with chemotherapy, radiotherapy, or supportive care alone, ($47,792; 95% CI, $43,254-$52,200; p = 0.061). In the Pan-Canadian study, the average cost to screen individuals with a high risk for developing lung cancer using LDCT and the average initial cost of curative intent treatment were lower than the average per-person cost of treating advanced stage lung cancer which infrequently results in a cure.

    Cost-effectiveness analyses often inform healthcare reimbursement decisions. The preferred measure of effectiveness is the quality adjusted life year (QALY) gained, where the quality of life adjustment is measured in terms of utility. Areas covered: We assessed the availability and variation of utility values for health states associated with advanced or metastatic non-small cell lung cancer (NSCLC) to identify values appropriate for cost-effectiveness models assessing alternative treatments. Our systematic search of six electronic databases (January 2000 to August 2015) found the current literature to be sparse in terms of utility values associated with NSCLC, identifying 27 studies. Utility values were most frequently reported over time and by treatment type, and less frequently by disease response, stage of disease, adverse events or disease comorbidities. Expert commentary: In response to rising healthcare costs, payers increasingly consider the cost-effectiveness of novel treatments in reimbursement decisions, especially in oncology. As the number of therapies available to treat NSCLC increases, cost-effectiveness analyses will play a key role in reimbursement decisions in this area. Quantifying the relationship between health and quality of life for NSCLC patients via utility values is an important component of assessing the cost effectiveness of novel treatments.

    Purpose: Studies of patients' preferences for localized prostate cancer treatments have assessed radical prostatectomy and external radiation therapy, but none of them has evaluated brachytherapy. The aim of our study was to assess the preferences and willingness to pay of patients with localized prostate cancer who had been treated with radical prostatectomy, external radiation therapy, or brachytherapy, and their related urinary, sexual, and bowel side effects. Methods and Materials: This was an observational, prospective cohort study with follow-up until 5 years after treatment. A total of 704 patients with low or intermediate risk localized prostate cancer were consecutively recruited from 2003 to 2005. The estimation of preferences was conducted using time trade-off, standard gamble, and willingness-to-pay methods. Side effects were measured with the Expanded Prostate Index Composite (EPIC), a prostate cancer-specific questionnaire. Tobit models were constructed to assess the impact of treatment and side effects on patients' preferences. Propensity score was applied to adjust for treatment selection bias. Results: Of the 580 patients reporting preferences, 165 were treated with radical prostatectomy, 152 with external radiation therapy, and 263 with brachytherapy. Both time trade-off and standard gamble results indicated that the preferences of patients treated with brachytherapy were 0.06 utilities higher than those treated with radical prostatectomy (P=.01). Similarly, willingness-to-pay responses showed a difference of €57/month (P=.004) between these 2 treatments. Severe urinary incontinence presented an independent impact on the preferences elicited (P<.05), whereas no significant differences were found by bowel and sexual side effects. Conclusions: Our findings indicate that urinary incontinence is the side effect with the highest impact on preferences and that brachytherapy and external radiation therapy are more valued than radical

    Surgery, chemotherapy, and radiation therapy are standard modalities for cancer treatment. Biological therapy (immunotherapy, biotherapy, or biological response modifier therapy) is a comparatively novel addition to this armamentarium. Biological therapies use the body's immune system, either directly or indirectly, to fight cancer or to lessen the side effects that may be caused by some cancer treatments. Biological therapeutic agents include interferons, interleukins, colony-simulating factors, monoclonal antibodies, vaccines, gene therapy, and nonspecific immunomodulating agents. A promising form of cancer treatment is immunotherapy. Immunotherapy for cancer is essentially the stimulation of the immune system through a variety of reagents such as vaccines, infusion of T-cells, or cytokines. These reagents act through one of several mechanisms including stimulating the anti-tumour response, decreasing suppressor mechanisms, altering tumour cells to increase their immunogenicity and making them more susceptible to immunologic defenses, and improving tolerance to cytotoxic agents or radiotherapy. This review describes some novel approaches in the immunotherapy in cancer. (author)

    This study monitored women (N = 76) with breast cancer from diagnosis through 1 year, and tested constructs from subjective expected utility theory with regard to their ability to predict patients' choice of surgical treatment as well as psychological distress and well-being over time. Women's positive expectancies for the consequences of treatment generally were maintained in favorable perceptions of outcome in several realms (i.e., physician agreement, likelihood of cancer cure or recurrence, self-evaluation, likelihood of additional treatment, partner support for option, attractiveness to partner). Assessed before the surgical decision-making appointment, women's expectancies for consequences of the treatment options, along with age, correctly classified 94% of the sample with regard to election of mastectomy versus breast-conserving procedures. Calculated from the point of decision making to 3 months later, expectancy disconfirmations and value discrepancies concerning particular treatment consequences predicted psychological adjustment 3 months and 1 year after diagnosis.

    Several prior studies have suggested that brachytherapy utilization has markedly decreased, coinciding with the recent increased utilization of intensity modulated radiation therapy, as well as an increase in urologist-owned centers. We sought to investigate the brachytherapy utilization in a large, hospital-based registry. Men with prostate cancer diagnosed between 2004-2012 and treated with either external beam radiation and/or prostate brachytherapy were abstracted from the National Cancer Database. In order to be included, men had to be clinically staged as T1c-T2aNx-0Mx-0, Gleason 6, PSA ≤ 10.0 ng/ml. Descriptive statistics were used to analyze brachytherapy utilization over time and were compared via χ(2). Multivariate logistic regression was used to assess for covariables associated with increased brachytherapy usage. There were 89,413 men included in this study, of which 37,054 (41.6%) received only external beam radiation, and 52,089 (58.4%) received prostate brachytherapy. The use of brachytherapy declined over time from 62.9% in 2004 to 51.3% in 2012 (p facilities (60.8% in 2004 to 47.0% in 2012, p facilities (63.7% in 2004 to 53.0% in 2012, p facilities than those who lived further. The use of intensity modulated radiation therapy increased during this same time period from 18.4% in 2004 to 38.2% in 2012 (p usage. In this hospital-based registry, prostate brachytherapy usage has declined for low risk prostate cancer as intensity modulated radiation therapy usage has increased. However, it still remains the treatment of choice for 51.3% of patients as of 2012.

    Sperm banking is an important procedure to preserve fertility before cancer therapy. The aim of this study was to comprehensively analyse cryopreservation activity retrospectively for 1080 patients referred to the sperm bank for sperm cryopreservation before cancer treatment. This study included 1007 patients diagnosed with testicular cancer (TC) (41.7%), lymphoma (26%), other haematological cancers (9.4%) or other types of cancer (22.8%); of these, 29 patients did not produce any semen sample and cryopreservation was impossible for 67 patients. Semen characteristics before treatment were within normal ranges, except moderate asthenospermia. Sperm concentration was significantly lower in TC than in non-TC. Straws from 57 patients (6.3%) were used in assisted reproductive technologies, which led to a 46.8% cumulative birth rate. Straws were destroyed for 170 patients (18.7%) and 140 patients performed semen analyses after cancer therapy. After an average delay of 22.5 months after the end of therapy, 43 patients (30.7%) exhibited azoospermia. This study of a large population of cancer patients revealed a high level of successful sperm storage. Utilization of cryopreserved spermatozoa led to good chances of fatherhood. Nevertheless, sperm banks should be aware of the low rates of straw use and straw destruction by cancer patients. Copyright © 2011 Reproductive Healthcare Ltd. Published by Elsevier Ltd.

    Purpose: To study the first trial patient in which an electronic brachytherapy (EBT) x-ray source is utilized for treatment of cervical cancer. Methods: During patient treatment, a miniaturized x-ray source was used in combination with a customized titanium tandem and ovoid applicator set. The semi-specialized source was modeled with formalisms outlined by AAMP Task Group 43. Multiple models were used to compensate for variable attenuation conditions as a function of source positions. Varian Brachyvision treatment planning software was utilized on CT data sets for dose calculations prior to treatment delivery. The dose was prescribed to “point A” as defined by American Brachytherapy society. Additional treatments plans were created from those clinically utilized in patient care and were recalculated for an existing Ir-192 source model. Dose volume histograms (DVH) and point dose calculations were compared between the modalities for the clinical condition present in patients treated with EBT. Results: Clinical treatment times, though longer than those typically experienced by Ir-192 users, were manageable. Instantaneous dose rates at personal positions within the treatment vault were lower than those measured during intra operative radiation therapy and breast EBT treatments. Due to lower average photon energy in EBT, dose gradients within the treatment plans were as expected steeper than those observed in Ir-192 based brachytherapy. DVH comparisons between Ir-192 and EBT treatments showed an expected decrease in the integral dose to normal tissues of interest for EBT. In comparing plans created for EBT delivery with those calculated for Ir-192, average dose values for EBT were more than 4%, 11%, and 9% lower at predefined bladder, rectum and “point B” positions, respectively. Conclusion: For the first time, we have demonstrated that the utilizing electronic brachytherapy system for tandem and ovoid based treatment of cancer of the cervix is feasible, and

    There are many methods of treating laryngeal cancers: definitive irradiation with or without concurrent chemotherapy, endoscopic laser surgery, partial surgery techniques, and total laryngectomy. Few studies have been reported on vocal function and quality of life of patients after the definitive treatment for laryngeal cancer, using single voice related QOL measures. The aim of this study was to examine voice related QOL in patients treated with various modalities using a Voice-Related Quality of Life (V-RQOL) questionnaire as well as Voice Handicap Index-10 (VHI-10) questionnaire. Between August 2006 and May 2007, survey data on voice utilizing the V-RQOL and VHI-10 were obtained from a total of 130 patients who had received definitive treatment for laryngeal cancers with follow-up at the Hokkaido University Hospital, and who were alive with no evidence of malignancy at the time of survey. Mean V-RQOL scores of the patients who received radiation therapy (n=63), chemoradiotherapy (n=29), laser resection (n=14) and total laryngectomy (n=27) as the final treatment for laryngeal cancer were 92.6, 92.9, 85.5, and 68.4, respectively. Mean VHI-10 values were 2.87, 2.34, 5.43, and 11.26. Such measures of quality of life are important endpoints to help judge the overall effectiveness of treatment options for laryngeal cancers.

    Full Text Available Genomics is the science of how genes influence human health and disease states. It differs from traditional genetic screening in that the transcriptional activity (or other markers in full panels of related genes are studied. Compared to simple genetic testing, assessment of expression levels in a panel of genes provides a more nuanced and holistic understanding of genetic modulation of human disease. Genomic testing may be used to great effect in resolving controversial questions on detection and treatment of prostate cancer. Genomic tests are currently in use for numerous facets of prostate cancer care, including screening, biopsy, and treatment planning. The clinical validity (predictive capacity of these assays has been well established; studies on clinical utility (i.e. usefulness of these tests in guiding patient/provider decisions have shown promising results. Men’s health specialists should be familiar with the role genomic testing will play in contemporary management of prostate cancer.

    In the U.S., black men are at higher risk than white men for lung cancer mortality whereas rates are comparable between black and white women. This paper draws from empirical work in lung cancer, mental health and health disparities to highlight that race and depression may overlap in predicting lower treatment access and utilization and poorer quality of life among patients. Racial barriers to depression identification and treatment in the general population may compound these risks. Prospective data are needed to examine whether depression plays a role in racial disparities in lung cancer outcomes. PMID:23514250

    Cancer patients face difficulties in accessing legally mandated benefits and accommodations when they return to the workplace. Poor employer-employee communication inflates these difficulties. Although proven methods to facilitate physician-patient communication exist, these have not been applied to the workplace. Thus, we aimed to assess the feasibility and utility of applying these methods to educate patients about their workplace rights and provide them with communication skills training to aid their conversations with their employers. A DVD was produced to educate patients and facilitate workplace communication. Participants consisted of 28 solid tumor cancer patients (14 women and 14 men) who completed primary cancer treatment in the past 12 months and were employed at the time of diagnosis. Participants watched a communication skills training DVD and completed a telephone interview. The interview elicited information about workplace experiences and evaluation of the DVD training program. The physician-patient communication skills training model utilized was successfully translated to the employer-employee setting. All but one participant found the DVD useful and easy to understand and indicated a high degree of confidence in using the communication skills to help them ask for workplace accommodations. All participants agreed that it would help newly diagnosed patients in discussions with their employers. Our data provides promising preliminary evidence that patient communication skills training can be applied to the workplace setting and is a welcomed aid to newly diagnosed cancer patients in their discussions with employers regarding the impact of treatment on their work performance and needs for accommodations.

    Targeted therapies have become important treatment options for cancer care in many countries. This study aimed to examine recent trends in utilization of antineoplastic drugs, particularly the use of targeted therapies for treatment of cancer, by geographic region in Taiwan (northern, midwestern, southern, and eastern regions and the outer islands). This was a retrospective observational study of antineoplastic agents using 2009-2012 quarterly claims data from Taiwan's National Health Insurance Research Database. Yearly market shares by prescription volume and costs for targeted therapies among total antineoplastic agents by region were estimated. We used multivariate regression model and ANOVA to examine variations in utilization of targeted therapies between geographic regions and used ARIMA models to estimate longitudinal trends. Population-adjusted use and costs of antineoplastic drugs (including targeted therapies) were highest in the southern region of Taiwan and lowest in the outer islands. We found a 4-fold difference in use of antineoplastic drugs and a 49-fold difference in use of targeted therapies between regions if the outer islands were included. There were minimal differences in use of antineoplastic drugs between other regions with about a 2-fold difference in use of targeted therapies. Without considering the outer islands, the market share by prescription volume and costs of targeted therapies increased almost 2-fold (1.84-1.90) and 1.5-fold (1.26-1.61) respectively between 2009 and 2012. Furthermore, region was not significantly associated with use of antineoplastic agents or use of targeted therapies after adjusting for confounders. Region was associated with costs of antineoplastic agents but it was not associated with costs of targeted therapies after confounding adjustments. Use of antineoplastic drugs overall and use of targeted therapies for treatment of cancer varied somewhat between regions in Taiwan; use was notably low in the outer

    To present information on predictors of treatment utilization and barriers to treatment utilization among individuals with lifetime DSM-5 cannabis use disorder (CUD). Face-to-face survey of a representative sample of the adult US general population (n=36,309). Treatment rates for CUD were low in this general population survey (13.7%). Severity of CUD and comorbidity of other lifetime drug use disorders were significant predictors of lifetime treatment utilization for CUD. Preference for self-reliance, minimizing problems, fear of stigma, and financial and structural issues were among the most frequently endorsed reasons for respondents not seeking treatment when they perceived the need for treatment among individuals with lifetime CUD, regardless of whether they eventually utilized treatment at some time in their lives. Given the rising prevalence of CUD in the US over the past decade and currently low treatment rates for CUD, increased provision for services for CUD appears critically needed, especially those that screen for and treat, when present, other drug use disorders. Programs to reduce stigma and financial barriers are needed, as well as programs to increase awareness among the general public, health care professionals about the nature and seriousness of CUD, and the availability and effectiveness of treatment for this disorder.

    Peculiarities of thyroid cancer, producing direct influence on selection of treatment procedure are enumerated. It is shown that surgical treatment is the determining way of treatment, which is supplemented with hormonotherapy in case of differentiated forms of the tumor. In case of anaplasia cancer, sarcomas, propagation of tumor beyond the limits of the organ, inoperable processes, treatment of recurrences and functional inactivity of bone metastases the remote control gamma-therapy should be performed. Therapy by radioactive iodine is shown for the treatment of remote iodine-concentrating metastases for devitalization of residual thyroid tissue after thyroidectomy

  18. Fertility effects of cancer treatment.

    2003-01-01

    Cancer sufferers are a subfertile group, and most treatments have the potential to adversely affect gonadal function. As cancer treatment becomes more effective and survival rates improve there are more cancer survivors in the reproductive age group for whom parenting is an important consideration. This article outlines the effects on fertility of cancer treatments and techniques to minimise the risk of infertility. The overall prospects for younger cancer sufferers to either retain their fertility or have genetic offspring is now better than ever before, due to advances in assisted reproductive technology, the appropriate use of fertility sparing surgery and other techniques to reduce the toxicity of therapy on the reproductive organs. These advances raise new moral and ethical concerns that must be considered before advising cancer sufferers of the options for preserving reproductive capacity.

    The current study was performed to characterize the employment status of survivors of hematological cancer who have an informal caregiver from the time of diagnosis through the first 6 months of treatment. Using a mixed methods approach, semistructured interviews with survivors of hematological cancer were conducted within 6 months of the initiation of cancer treatment. Interviews assessed cancer treatment status, barriers and facilitators to employment, financial and insurance status, and relationship with the primary caregiver. These results are part of a longitudinal study of cancer survivors and informal caregivers. A total of 171 patients were enrolled. Within 6 months of beginning cancer treatments, approximately 35% were no longer employed. Reasons to remain employed included financial need, employee benefits, and a sense of purpose and normalcy. Employer accommodations and supportive colleagues facilitated continued employment. Logistic regression analysis demonstrated that having a higher household income, a desire to work, nonphysical job tasks, and congruent survivor-caregiver communication were associated with greater odds of remaining employed. Within 6 months of initiating cancer treatment, the majority of survivors of hematological cancer had maintained employment. Because of the limitations imposed by the physical stress of cancer treatments, as well as the need to maintain employment to continue receiving employee benefits to cover such treatments, survivors of hematological cancer likely would benefit from employment accommodations that are sensitive to their unique needs.

    To develop a successful formulation for the gene therapy of breast cancer, an effective therapeutic nucleic acid and a proper delivery system are essential. Increased understanding of breast cancer, and developments in biotechnology, material science and nanotechnology have provided a major impetus in the development of effective formulations for the gene therapy of breast cancer. Areas covered: We discuss DNA/RNA-based formulations that can inhibit the growth of breast cancer cells and control the progress of breast cancer. Targets for the gene therapy of breast cancer, DNA/RNA-based therapeutics and delivery systems are summarized. And examples of successful DNA/RNA-based formulations for breast cancer gene therapy are reviewed. Expert opinion: Several challenges remain in developing effective DNA/RNA-based formulations for treatment of breast cancer. Firstly, most of the currently utilized targets are not effective enough as monotherapy for breast cancer. Secondly, the requirements for co-delivery system make the preparation of formulation more complicated. Thirdly, nanoparticles with the modification of tumor-targeting ligands could be more unstable in circulation and normal tissues. Lastly, immune responses against the viral vectors are unfavorable for the gene therapy of breast cancer because of the damage to the host and the impaired therapeutic ability.

    The paper establishes the utility of the fiber- optic bronchoscopy (FOB) studies performed in patients with esophageal cancer (EC) and confirm the possibility of tracheo-bronchial compromise. We carry out a descriptive study in 226 patients with esophageal cancer during 1991 to 1996 in the Instituto Nacional de Cancerologia of Colombia (INC). We excluded the patients with previous treatments: radiotherapy or surgery, and others primary cancers with metastases on the esophagus. We analyzed gastric, intestinal and general symptoms, smoking habits, primary cancer location, histological types, radiologic findings, fob findings, micro and macroscopes, and results of the samples: transbronchial, endobronchial biopsies, bronchi alveolar lavage and brush. We included 158 patients, 110 male and 48 female, with age between 32 and 83 years, symptoms duration average of 5,2 months. The most significant were cough, dysphonia and sputum. The location of EC was statistics significance only in the upper third escamocelular type. The significant radiological findings were: parenchymal nodules and interstitial infiltrates, the significant fob findings were: fistula endobronchial infiltration endobronchial mass and vocal cords palsy. The zones with more compromise were trachea, principal bronchi and vocal cords. Only 17 patients were positives in the samples; comparing the histopathologic findings (biopsies) as the gold standard with fob findings the sensitivity was 100%, specificity 35%, positive predictive value 15.6% and negative predictive value 100%

    2018-06-05

    The prognosis of colorectal cancer in UICC stage IV has been improved in the last decades by improvements in interdisciplinary treatment. Treatment strategies for oligometastasized colorectal cancer are developing more and more into an individualized treatment. An overview of the current literature of modern treatment concepts in oligometastasized colorectal cancer UICC stage IV is given. Surgery still has the supreme mandate in resectable colorectal liver metastases, as neoadjuvant and adjuvant treatment strategies to not provide any benefits for these patients. In marginal or non-resectable stages systemic treatment is superior in these patients depending on the prognostic parameters. Also in curative settings local treatment options should be considered as a reasonable additive tool. An interesting treatment approach for isolated liver metastases and non-resectable colorectal cancer is liver transplantation. Irrespective of new developments in treatment strategies for metastasized colorectal cancer, resection of colorectal liver metastases remains the gold standard whenever possible.

  4. Utilizing temporal variations in chemotherapeutic response to improve breast cancer treatment efficacy

    2015-09-01

    Full Text Available Though survival rates for women with stage I breast cancer have radically improved, treatment options remain poor for the 40% of women diagnosed with later-stage disease. For these patients, improved chemotherapeutic treatment strategies are critical to eradicate any disseminated tumor cells. Despite many promising new drugs in vitro, most ultimately fail in the clinic. One aspect often lost during testing is in vivo circulation half-lives rarely exceed 24 hours, whereas in vitro studies involve drug exposure for 2-3 days. Here, we show how mimicking these exposure times alters efficacy. Next, using this model we show how drug response is highly time-dependent by extending analysis of cell viability out to two weeks. Variations in response both with feeding and time were dependent on drug mechanism of action. Finally, we show that by implementing this temporal knowledge of drug effects to optimize scheduling of drug administration we are able to regain chemosensitivity in a Carboplatin-resistant cell line.

    This population-based analysis examined the prevalence of periodontal diseases along with the self-perceived oral health and patterns of dental care utilization of breast cancer survivors in the United States. Data from the 1999-2004 National Health and Nutrition Surveys were utilized, examining information from 3,354 women between 50 and 85 years of age. Primary outcomes were gingivitis and periodontitis, self-perceived oral health, and dental care utilization. Logistic regression analyses were used to estimate relationships of breast cancer diagnosis and primary outcomes while controlling for confounding factors. Breast cancer survivors were more likely to be older than 55 years, white, nonsmokers, have higher levels of education and income, and a higher prevalence of osteoporosis. Breast cancer survivors were significantly less likely to have dental insurance (P = 0.04). Utilization of dental services and reason for last dental visit did not significantly differ between groups. A history of a breast cancer diagnosis did not increase the odds of gingivitis [odds ratio (OR):  1.32; 95 percent confidence interval (CI): 0.53-3.63], periodontitis (OR: 1.82; 95 percent CI:  0.89-4.01), or poor self-perceived oral health (OR: 0.89; 95 percent CI: 0.61-1.33) after adjusting for age, race, education, dental care utilization, and smoking status. In this sample, a history of breast cancer does not significantly impact periodontal health, self-perceived oral health, and dental care utilization. However, efforts should be made to assure that breast cancer survivors have dental insurance. © 2015 American Association of Public Health Dentistry.

    Directory of Open Access Journals (Sweden)

    2017-10-01

    Full Text Available Current standard therapies for cancer, including surgery, anti-cancer drugs, and radiotherapy, are thought to contribute to the improvement in the survival rates of cancer patients. However, such standard therapies have 3 major problems: in advanced cancers, it is unlikely that standard cancer treatments will cure the disease; adverse side effects that accompany standard cancer treatments put many patients in distress; and a large amount of medical expenditure is required for new and expensive anti-cancer drugs. These problems may be viewed as a result of establishing treatments without any consideration regarding the root cause of the cancer. Otto Warburg suggested that particular changes in the energy metabolism of cells, which are associated with a shortage of oxygen, are the root cause of cancer. Cancer cells have unique metabolic characteristics, and thus we believe that it is important to treat cancer as a metabolic disease. More specifically, not only is it important to suppress cancer cell metabolism, but it is also important to improve the chronic inflammation that is associated with the development and progression of cancer, and to support the functions of immune cells. This type of view of cancer treatment coincides with the principles of Chinese medicine, which has a history of 4000 years, such as “fuzheng quxie” and “zhibing qiuben”, which can assist in the establishment of cancer treatments for patients. In this article, we discuss cancer treatments from the view of cancer as a metabolic disease and their association with Chinese medicine, and introduce some clinical cases along with a review of the literature.

    Full Text Available The majority of pancreatic cancer diagnoses are made at the advanced stage and when metastasis has already occurred, and the 1- and 5-year survival rates are extremely low. Cemcitabine remains the most frequently applied treatment option, yet the most effective chemotherapeutic agents and combinations with multiple agents and/or radiotherapy only marginally improve patient survival and may even establish an environment conducive to cancer cells with stem cell-like characteristics. An alternative treatment modality, cryoablation, is available and has been applied at our institute to patients with unresectable pancreatic cancer since 2001. In this article, we present our collective experience with patient outcome using cryoablation, alone or combined with other treatment modalities such as brachytherapy (125iodine seed implantation. The overall outcomes have been encouraging, suggesting that comprehensive therapy including cryoablation may prolong the survival of patients with advanced or metastatic pancreatic cancer, and we are achieving particular success with a novel combination of percutaneous cryoablation, cancer microvascular intervention with 125iodine seed implantation, and combined immunotherapy (3C applied using an individualized patient strategy (P. The 1- through 10-year survival rates of 145 patients treated with the so-called “3C+P model” are presented in support of this new strategy as a promising new treatment for advanced and metastatic cancer

  12. The role of PET/CT in radiation treatment planning for cancer patient treatment

    International Nuclear Information System (INIS)

    2008-10-01

    Positron emission tomography (PET) and, more recently, integrated positron emission tomography/X ray computed tomography (PET/CT) have appeared as significant diagnostic imaging systems in clinical medicine. Accurate recognition of cancers in patients by means of PET scanning with Fluorine-18-fluorodeoxyglucose ( 18 F-FDG) has illustrated a need to determine a mode of therapy to achieve better prognoses. The clinical management of cancer patients has improved dramatically with the introduction of clinical PET. For treatment of cancer patients, on the other hand, radiation therapy (RT) plays an important role as a non-invasive therapy. It is crucial that cancers are encompassed by high dose irradiation, particularly in cases of curative RT. Irradiation should precisely target the entire tumour and aim to minimise the size of microscopic extensions of the cancer, as well as minimize radiation damage to normal tissues. A new imaging technique has therefore been sought to allow precise delineation of the cancer target to be irradiated. Clinical PET, combined with utilization of 18 F-FDG, may have an important role in radiation treatment planning (RTP) in lung cancer. In addition to determining if RT is appropriate and whether therapy will be given with curative or palliative intent, 18 F-FDG-PET is useful for determining therapy ports. It can be used both to limit ports to spare normal tissue and to include additional involved regions. Several studies have shown that PET has an impact on RTP in an important proportion of patients. It is to be hoped that treatment plans that include all the 18 F-FDG-avid lesions or the 18 F-FDG-avid portions of a complex mass will result in more effective local control with less unnecessary tissue being treated. The IAEA has placed emphasis on the issue of application of clinical PET for radiation treatment planning in various cancer patients. Two consultants meetings were held in 2006 and their results are summarized into this IAEA

    2018-01-01

    Testicular function and future fertility may be affected by cancer treatment during childhood. Whilst survival of the germ (stem) cells is critical for ensuring the potential for fertility in these patients, the somatic cell populations also play a crucial role in providing a suitable environment to support germ cell maintenance and subsequent development. Regulation of the spermatogonial germ-stem cell niche involves many signalling pathways with hormonal influence from the hypothalamo-pituitary-gonadal axis. In this review, we describe the somatic cell populations that comprise the testicular germ-stem cell niche in humans and how they may be affected by cancer treatment during childhood. We also discuss the experimental models that may be utilized to manipulate the somatic environment and report the results of studies that investigate the potential role of somatic cells in the protection of the germ cells in the testis from cancer treatment.

    -saving therapies. Patient preferences and quality of life are important issues due to the short survival of patients with advanced ovarian cancer. Two cost-utility studies reported similar incremental cost-utility ratios (ICURs). In the study based on US costs, the ICUR of paclitaxel/cisplatin treatment was US $18,200 per additional quality-adjusted life-year (QALY) [1995 drug costs]. In a Canadian study the ICUR ranged from 11,600 Canadian dollars ($Can) to $Can 24,200 (1996 costs) per additional progression-free QALY depending on the choice of second-line treatment. Paclitaxel used in combination with cisplatin offers survival and utility gains versus cyclophosphamide plus cisplatin, when used as first-line treatment in patients with stage III or IV ovarian cancer. The incremental cost for these gains is within the accepted range for healthcare interventions. However, pharmacoeconomic analyses of paclitaxel plus carboplatin--a combination widely accepted for use in women with advanced ovarian cancer and with clinical advantages over paclitaxel plus cisplatin in terms of ease of administration and tolerability profile--are currently lacking. Nevertheless, results of available pharmacoeconomic data support the clinical use of paclitaxel/platinum combinations, particularly paclitaxel plus cisplatin, as a first-line chemotherapy treatment option in patients with advanced ovarian cancer.

    Among frequently-used tumor markers in lung cancer, carcinoembryonic antigen (CEA) and carbohydrate antigen 125 (CA125), cytokeratin 19 (CYFRA21-1) and squamous carcinoma antigen (SCC), neuron specific enolase (NSE) and pro-gastrin-releasing peptide (ProGRP) are respectively expressed highly in lung adenocarcinoma, lung squamous carcinoma and small cell lung cancer. By comparing patients with multiple increased tumor markers (group A) and patients with increase of CEA and/or CA125 (group B), this study aims to investigate the utility of multiple increased tumor markers in therapeutic evaluation and prediction of disease relapsing in patients with advanced lung adenocarcinoma. Patients with stage IV lung adenocarcinoma who receiving the first line chemotherapy in Cancer Hospital, Chinese Academy of Medical Sciences were enrolled and retrospectively analyzed. Clinical characteristic, serum tumor markers before chemotherapy, efficacy evaluation, progression-free survival (PFS) were analyzed. Except CEA and CA125, the highest ratio of increased tumor markersin group A was CYFRA21-1 (93%), then was NSE (36%), SCC (13%) and ProGRP (12%). Patients with multiple increased tumor markers tend to have more distant metastasis (Ptumor markers have high risk of relapse, and maintenance therapy can reduce relapse risk.

    To use health economics methodology to assess the screening program on gastric cancer in Zhuanghe, China, so as to provide the basis for health decision on expanding the program of early detection and treatment. The expense of an early detection and treatment program for gastric cancer in patients found by screening, and also costs of traditional treatment in a hospital of Zhuanghe were assessed. Three major techniques of medical economics, namely cost-effective analysis (CEA), cost-benefit analysis (CBA) and cost-utility analysis (CUA), were used to assess the screening program. RESULTS from CEA showed that investing every 25, 235 Yuan on screening program in Zhuanghe area, one gastric cancer patient could be saved. Data from CUA showed that it was cost 1, 370 Yuan per QALY saved. RESULTS from CBA showed that: the total cost was 1,945,206 Yuan with a benefit as 8,669,709 Yuan and an CBR of 4.46. The early detection and treatment program of gastric cancer appears economic and society-beneficial. We suggest that it should be carry out in more high risk areas for gastric cancer.

    efficiency of cancer therapy and reducing harm to normal cells. Finally, we propose a novel idea to combine static magnetic field (SMF) with CAP as a tool for cancer therapy. The breast cancer cells MDA-MB-231 showed a significant decrease in viability after direct plasma treatment with SMF (compared to only plasma treatment). In addition, cancer cells treated by the CAP-SMF-activated media (indirect treatment) also showed viability decrease but slightly weaker than the direct plasma-MF treatment. When treated by plasma with MF, mouse wild type dermal fibroblasts (WTDF) show no difference from the plasma treatment, both directly and indirectly. By integrating the use of MF and CAP, we are able to discover their advantages that are yet to be utilized. Although plasma can selectively kill cancer cells, long time exposure can still damage the normal cells around the tumor. This prompts researchers to seek for novel ideas in the designing of plasma treatment. This study provides the idea of combining the proper dosage of cold atmospheric plasma, AuNPs and MF in order to achieve the enhanced killing effect on cancer cells.

    In Thailand, there has been no economic evaluation study of adjuvant chemotherapy for stage III colon cancer patients after resection. This study aims to evaluate the cost-utility of all chemotherapy regimens currently used in Thailand compared with the adjuvant 5-fluorouracil/leucovorin (5-FU/LV) plus capecitabine as the first-line therapy for metastatic disease in patients with stage III colon cancer after resection. A cost-utility analysis was performed to estimate the relevant lifetime costs and health outcomes of chemotherapy regimens based on a societal perspective using a Markov model. The results suggested that the adjuvant 5-FU/LV plus capecitabine as the first-line therapy for metastatic disease would be the most cost-effective chemotherapy. The adjuvant FOLFOX and FOLFIRI as the first-line treatment for metastatic disease would be cost-effective with an incremental cost-effectiveness ratio of 299,365 Thai baht per QALY gained based on a societal perspective if both prices of FOLFOX and FOLFIRI were decreased by 40%.

  4. The cost-effectiveness and cost-utility of high-dose palliative radiotherapy for advanced non-small-cell lung cancer

    International Nuclear Information System (INIS)

    Coy, Peter; Schaafsma, Joseph; Schofield, John A.

    2000-01-01

    Purpose: To compute cost-effectiveness/cost-utility (CE/CU) ratios, from the treatment clinic and societal perspectives, for high-dose palliative radiotherapy treatment (RT) for advanced non-small-cell lung cancer (NSCLC) against best supportive care (BSC) as comparator, and thereby demonstrate a method for computing CE/CU ratios when randomized clinical trial (RCT) data cannot be generated. Methods and Materials: Unit cost estimates based on an earlier reported 1989-90 analysis of treatment costs at the Vancouver Island Cancer Centre, Victoria, British Columbia, Canada, are updated to 1997-1998 and then used to compute the incremental cost of an average dose of high-dose palliative RT. The incremental number of life days and quality-adjusted life days (QALDs) attributable to treatment are from earlier reported regression analyses of the survival and quality-of-life data from patients who enrolled prospectively in a lung cancer management cost-effectiveness study at the clinic over a 2-year period from 1990 to 1992. Results: The baseline CE and CU ratios are $9245 Cdn per life year (LY) and $12,836 per quality-adjusted life year (QALY), respectively, from the clinic perspective; and $12,253/LY and $17,012/QALY, respectively, from the societal perspective. Multivariate sensitivity analysis for the CE ratio produces a range of $5513-28,270/LY from the clinic perspective, and $7307-37,465/LY from the societal perspective. Similar calculations for the CU ratio produce a range of $7205-37,134/QALY from the clinic perspective, and $9550-49,213/QALY from the societal perspective. Conclusion: The cost effectiveness and cost utility of high-dose palliative RT for advanced NSCLC compares favorably with the cost effectiveness of other forms of treatment for NSCLC, of treatments of other forms of cancer, and of many other commonly used medical interventions; and lies within the US $50,000/QALY benchmark often cited for cost-effective care

    Full Text Available Currently there are more than 13.7 million cancer survivors living in the U.S., and that figure is projected to increase by 31% in the next decade, adding another 4 million cancer survivors into the healthcare system. Cancer is largely a disease of aging, and the aging of the population will sharply raise the proportion of older cancer survivors, many of whom will be long-term survivors (5+ years post diagnosis. This review will address the potential utility of exercise to address three health problems that are of particular concern for the aging cancer survivor and the healthcare system, i.e., disability, falls, and cardiovascular disease, because the development of these age-related problems may be accelerated by cancer treatment. While there are many different modes of exercise that each produce specific adaptations, Tai Ji Quan may be a particularly suitable strategy to mitigate the development of age- and cancer-treatment-related problems. Based on studies in older adults without cancer, Tai Ji Quan produces musculoskeletal and cardiometabolic adaptations and is more easily performed by older adults due to its low energy cost and slower movement patterns. Since cancer survivors are mostly older, inactive, and often physically limited by the lingering side effects of treatment, they need to engage in safe, practical, and effective modes of exercise. The dearth of published controlled trials examining the efficacy of Tai Ji Quan to mitigate cancer-treatment-related musculoskeletal and cardiovascular side effects points to ample research opportunities to explore the application of this non-Western exercise modality to improve long-term outcomes for aging cancer survivors.

    This study aimed to compare radiation only or chemo radiation treatment of local advanced cervical cancers by examining the initial response of tumors and acute side effects. An initial assessment employed value based medicine (VBM) by obtaining utility values for both types of therapy. The incidences of acute lower gastrointestinal, genitourinary, and hematology side effects in patients undergoing chemoradiation did not differ significantly from those undergoing radiation alone. Utility values for patients who underwent radiation alone were higher compared to those who underwent chemoradiation. It was concluded that the complete response of patients who underwent chemoradiation did not differ significantly from those who underwent radiation alone.

    from the European Organisation for the Research and Treatment of Cancer's core HRQOL questionnaire, Quality of Life Questionnaire (QLQ-C30, given its well-established domain structure.Methods: QLQ-C30 (Version 3 data were collected from 356 patients receiving palliative radiotherapy for recurrent/metastatic cancer (various primary sites. The dimensional structure of the QLQ-C30 was tested with EFA and CFA, the latter informed by the established QLQ-C30 structure and views of both patients and clinicians on which are the most relevant items. Dimensions determined by EFA or CFA were then subjected to Rasch analysis.Results: CFA results generally supported the proposed QLQ-C30 structure (comparative fit index =0.99, Tucker–Lewis index =0.99, root mean square error of approximation =0.04. EFA revealed fewer factors and some items cross-loaded on multiple factors. Further assessment of dimensionality with Rasch analysis allowed better alignment of the EFA dimensions with those detected by CFA.Conclusion: CFA was more appropriate and efficient than EFA in producing clinically interpretable results for the HSCS for a proposed new cancer-specific MAUI. Our findings suggest that CFA should be recommended generally when deriving a preference-based measure from a HRQOL measure that has an established domain structure.Keywords: multi attribute utility instrument, health state classification system, confirmatory factor analysis, exploratory factor analysis, European Organisation for the Research and Treatment of Cancer QLQ-C30

    In this review, we highlight the current concepts and discuss some of the current challenges and future prospects in cancer therapy. We frequently use the example of lung cancer. We conducted a nonsystematic PubMed search, selecting the most comprehensive and relevant research articles, clinical trials, translational papers, and review articles on precision oncology and immuno-oncology. Papers were prioritized and selected based on their originality and potential clinical applicability. Two major revolutions have changed cancer treatment paradigms in the past few years: targeting actionable alterations in oncogene-driven cancers and immuno-oncology. Important challenges are still ongoing in both fields of cancer therapy. On the one hand, druggable genomic alterations are diverse and represent only small subsets of patients in certain tumor types, which limits testing their clinical impact in biomarker-driven clinical trials. Next-generation sequencing technologies are increasingly being implemented for molecular prescreening in clinical research, but issues regarding clinical interpretation of large genomic data make their wide clinical use difficult. Further, dealing with tumor heterogeneity and acquired resistance is probably the main limitation for the success of precision oncology. On the other hand, long-term survival benefits with immune checkpoint inhibitors (anti-programmed death cell protein-1/programmed death cell ligand-1[PD-1/L1] and anti-cytotoxic T lymphocyte antigen-4 monoclonal antibodies) are restricted to a minority of patients, and no predictive markers are yet robustly validated that could help us recognize these subsets and optimize treatment delivery and selection. To achieve long-term survival benefits, drug combinations targeting several molecular alterations or cancer hallmarks might be needed. This will probably be one of the most challenging but promising precision cancer treatment strategies in the future. Targeting single molecular

    To evaluate the inherent value of breast cancer therapy a willingness-to-pay (WTP) study was conducted in Korean patients with metastatic breast cancer. Patients were prospectively enrolled from four study centers and completed quality of life questionnaires to reflect their status pre-cancer and their current health status. Clinical and socioeconomic data were collected to characterize the population and utilize during modeling. Patients' WTP for breast cancer treatment was assessed using an open-ended question following three rounds of bidding to better hone in on their maximal WTP, starting with one of three randomly assigned start bids. Predictors of patient WTP was evaluated using linear regression models. Associations between WTP and other parameters were evaluated with correlations. Korean metastatic breast cancer patients were WTP an average of KRW 8 696 329 (US$7555) per month to return to their pre-cancer health state, with those who were recently diagnosed as WTP the most (KRW 12 955 000 [$11 254]). WTP was closely associated with the patient's education level, income, personal financial difficulties, Eastern Cooperative Oncology Group performance status, and their experience of arm symptoms. The results suggest that patients are WTP significant amounts per month for treatment. Breast cancer patients are heavily burdened physically, mentally and financially, and the present study indicated this significant financial burden by disclosing its relationship with WTP. Providing a better understanding of the inherent value of treatment will allow Koreans to better evaluate treatment in the coming era of personalized medicine. © 2012 Wiley Publishing Asia Pty Ltd.

  15. Utility of PET in gynecological cancer

    International Nuclear Information System (INIS)

    Choi, Chang Woon

    2002-01-01

    Clinical application of positron emission tomography (PET) is rapidly increasing for the detection and staging of cancer at whole-body studies performed with 2-[fluorine-18] fluoro-2-deoxy-D-glucose (FDG). Although many cancers can be detected by FDG-PET, there has been limited clinical experience with FDG-PET for the detection of gynecological cancers including malignancies in uterus and ovary. FDG-PET can show foci of metastatic disease that may not be apparent at conventional anatomic imaging and can aid in the characterization of indeterminate soft-tissue masses. Most gynecological cancers need to surgical management. FDG-PET can improve the selection of patients for surgical treatment and thereby reduce the morbidity and mortality associated with inappropriate surgery. FDG-PET is also useful for the early detection of recurrence and the monitoring of therapeutic effect. In this review, I discuss the clinical feasibility and imitations of this imaging modality in patients with gynecological cancers

  16. Low Temperature Plasma for the Treatment of Epithelial Cancer Cells

    Science.gov (United States)

    Mohades, Soheila

    Biomedical applications of low temperature plasmas (LTP) may lead to a paradigm shift in treating various diseases by conducting fundamental research on the effects of LTP on cells, tissues, organisms (plants, insects, and microorganisms). This is a rapidly growing interdisciplinary research field that involves engineering, physics, life sciences, and chemistry to find novel solutions for urgent medical needs. Effects of different LTP sources have shown the anti-tumor properties of plasma exposure; however, there are still many unknowns about the interaction of plasma with eukaryotic cells which must be elucidated in order to evaluate the practical potential of plasma in cancer treatment. Plasma, the fourth state of matter, is composed of electrons, ions, reactive molecules (radicals and non-radicals), excited species, radiation, and heat. A sufficient dose (time) of plasma exposure can induce death in cancer cells. The plasma pencil is employed to study the anti-tumor properties of this treatment on epithelial cells. The plasma pencil has been previously used for the inactivation of bacteria, destroying amyloid fibrils, and the killing of various cancer cells. Bladder cancer is the 9th leading cause of cancer. In this dissertation, human urinary bladder tissue with the squamous cell carcinoma disease (SCaBER cells) is treated with LTP utilizing two different approaches: direct plasma exposure and Plasma Activated Media (PAM) as an advancement to the treatment. PAM is produced by exposing a liquid cell culture medium to the plasma pencil. Direct LTP treatment of cancer cells indicates a dose-dependent killing effect at post-treatment times. Similarly, PAM treatment shows an anti-cancer effect by inducing substantial cell death. Reactive oxygen species (ROS) and reactive nitrogen species (RNS) have an important role in the biomedical effects of LTP treatment. This study demonstrates the capability of the plasma pencil to transport ROS/RNS into cell culture media

  17. Theranostic nanoparticles for the treatment of cancer

    Science.gov (United States)

    Moore, Thomas Lee

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

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

    Smell and taste disorders, sicca symptoms, can be detected in patients with head and neck cancer. The purpose of this study was to assess the utility of local liposomal application in the treatment of patients with head and neck cancers. Ninety-eight patients with head and neck cancer were included in this study. The groups were defined as: group 1 = only surgery; group 2 = surgery + adjuvant radiochemotherapy; and group 3 = primarily radiochemotherapy. All patients had finished cancer treatment and received liposomal sprays for the nose and mouth for 2 months (LipoNasal, LipoSaliva; Optima Pharmaceutical GmbH, Germany) and suffered from taste and smell disorders. We performed tests with "Sniffin' Sticks," "Taste Strips," and a xerostomia questionnaire before and after treatment. After application of liposomes, patients demonstrated a statistically significant increase in smell and taste, and reduced xerostomia. Our results demonstrate that using nonpharmaceutical liposomal sprays improve smell, taste, and symptoms of xerostomia in patients with head and neck cancer. © 2015 Wiley Periodicals, Inc.

    2017-10-01

    Pancreatic cancer, adenocarcinoma, generally rapidly progresses, and if a metastatic lesion is detected, chemotherapy is applied even in solitary metastasis. However, surgical resection for solitary metastasis have been reported to achieve long survival in some pancreatic cancer patients. In a prospective study of surgery for hepatic and lymph node oligometastasis of pancreatic cancer, long survival of 5 years or more was reported around 10%. Furthermore, longer survival and fewer rerecurrence were achieved with surgery in lung metastasis than in liver metastasis and loco-regional recurrence. Although there has been no establishment of concept or no consensus of treatment strategy for oligometastasis in pancreatic cancer, some patients with pancreatic cancer have long disease-free survival by surgery for oligometastasis. A population of pancreatic cancer patients who have benefits of surgery for oligometastasis should be identified, and it is necessary to establish treatments for oligometastasis as standard treatments in pancreatic cancer.

  2. Clinical utility of pretreatment prediction of chemoradiotherapy response in rectal cancer: a review.

    2017-03-01

    Approximately 20% of all patients with locally advanced rectal cancer experience pathologically complete responses following neoadjuvant chemoradiotherapy (CRT) and standard surgery. The utility of radical surgery for patients exhibiting good CRT responses has been challenged. Organ-sparing strategies for selected patients exhibiting complete clinical responses include local excision or no immediate surgery. The subjects of this tailored management are patients whose presenting disease corresponds to current indications of neoadjuvant CRT, and their post-CRT tumor response is assessed by clinical and radiological examinations. However, a model predictive of the CRT response, applied before any treatment commenced, would be valuable to facilitate such a personalized approach. This would increase organ preservation, particularly in patients for whom upfront CRT is not generally prescribed. Molecular biomarkers hold the greatest promise for development of a pretreatment predictive model of CRT response. A combination of clinicopathological, radiological, and molecular markers will be necessary to render the model robust. Molecular research will also contribute to the development of drugs that can overcome the radioresistance of rectal tumors. Current treatments for rectal cancer are based on the expected prognosis given the presenting disease extent. In the future, treatment schemes may be modified by including the predicted CRT response evaluated at presentation.

    The human skeleton is the most common organ to be affected by metastatic cancer and bone metastases are a major cause of cancer morbidity. The five most frequent cancers in Malaysia among males includes prostate whereas breast cancer is among those in females, both being associated with skeletal lesions. Bone metastases weaken bone structure, causing a range of symptoms and complications thus developing skeletal-related events (SRE). Patients with SRE may require palliative radiotherapy or surgery to bone for pain, having hypercalcaemia, pathologic fractures, and spinal cord compression. These complications contribute to a decline in patient health- related quality of life. The multidimensional assessment of health-related quality of life for those patients is important other than considering a beneficial treatment impact on patient survival, since the side effects of treatment and disease symptoms can significantly impact health-related quality of life. Cancer treatment could contribute to significant financial implications for the healthcare system. Therefore, it is essential to assess the health-related quality of life and treatment cost, among prostate and breast cancer patients in countries like Malaysia to rationalized cost-effective way for budget allocation or utilization of health care resources, hence helping in providing more personalized treatment for cancer patients.

  4. Utility evaluations for Markov states of lung cancer for PET-based disease management

    2000-01-01

    Utilities for the health outcomes states (Markov states) of non-small cell lung carcinoma (NSCLCL) should be measured to evaluate management options for patients because patients are key participants in the process of care, and their assessment of diagnostic and therapeutic value in the options presented to them ultimately impacts their net health outcomes. This investigation sought to measure utilities for stage-dependent outcomes states of NSCLC. Persons (n=23) with suspected NSCLC based on physical findings and computed tomography completed a short utilities survey. Utility valuations were obtained according to severity of morbidity and varied considerably. Respondents rated these health states according to accuracy measures for 18 flurodeoxyglucose ( 18 FDG) positron emission tomography (PET) imaging and mediastinoscopy. The results demonstrate that stage-dependent morbidity is an important consideration for patients with NSCLC and should be included in any decision analysis regarding the evaluation or treatment of NSCLC. Respondents valued the quality of information obtained from non-invasive mediastinoscopy comparably. The utilities obtained from this investigation are useful in clinical decision-making based on Markov processes because they provide an initial estimation of utility assessment for 18 FDG-based diagnostic evaluation of lung cancer. Consequently, these utilities will be useful in future decision analyses that require patient preference in the assignment of the evaluation of decision options (branches)

    Circulating tumor cells (CTCs) are rare tumor cells and have been investigated as diagnostic, prognostic and predictive biomarkers in many types of cancer. Although CTCs are not currently used in clinical practice, CTC studies have accumulated a high level of clinical validity, especially in breast, lung, prostate and colorectal cancers. In this review, we present an overview of the current clinical validity of CTCs in metastatic and non-metastatic disease, and the main concepts and studies investigating the clinical utility of CTCs. In particular, this review will focus on breast, lung, colorectal and prostate cancer. Three major topics concerning the clinical utility of CTC are discussed-(1) treatment based on CTCs used as liquid biopsy, (2) treatment based on CTC count or CTC variations, and (3) treatment based on CTC biomarker expression. A summary of published or ongoing phase II and III trials is also presented.

    To assess breast cancer screening utilization in Medicare beneficiaries with colorectal and lung cancer versus cancer-free controls. Female fee-for-service Medicare beneficiaries who were ≥67 years old and diagnosed with lung or colorectal cancer between 2000 and 2011 and who reported to a Surveillance, Epidemiology, and End Results (SEER) registry (case group) were followed for 2 years after their diagnoses, unless death, a diagnosis of breast cancer, or the end of 2013 came first. A similar number of cancer-free controls were individually matched to cases by age, race, registry region, and follow-up time. Screening utilization was defined as the percentage of women with ≥1 screening mammogram during follow-up. Overall, 104,164 cases (48% colorectal, 52% lung; 30% advanced cancer) and 104,164 controls were included. Among women with lung or colorectal cancer, 22% underwent ≥1 screening mammogram versus 26% of controls (odds ratio [OR] 0.80; 95% confidence interval [CI] 0.78-0.82). Stratified by cancer type, 28% of colorectal cancer cases versus 29% of controls (OR 0.98; 95% CI 0.95-1.01) and 17% of lung cancer cases versus 23% of controls (OR 0.63; 95% CI 0.60-0.65) received ≥1 mammogram. When stratified by stage, 8% with advanced cancer versus 18% of controls (OR 0.33; 95% CI 0.31-0.35) and 30% with early-stage cancer versus 30% of controls (OR 1; 95% CI 0.97-1.02) underwent ≥1 mammogram. Screening mammography utilization rates are similar between Medicare beneficiaries with early-stage cancer versus controls. Although the majority of patients with advanced-stage cancer appropriately do not pursue screening mammography, a small number (8%) continue with screening.

    1981-07-01

    Intraoperative irradiation, thermotherapy, hypoxic cell sensitizer, and neutron brachytherapy were used for locally advanced cancer and value and limitations of these therapies were discussed. Intraoperative irradiation was mainly used for cancers of the gastro-intestinal tract. In stage I gastric cancers, no difference in the five-year survival rates was found between the groups with and without intraoperative irradiation. In gastric cancers of stage II or more, intraoperative irradiation had a favourable effect. Thermotherapy was applied to superficial radio-resistant cancer by the use of a thermal system of microwave- and radio-frequency heating. This treatment induced disappearance of approximately 50% of tumor. For the treatment with hypoxic cell sensitizer, studies of phase I and II with Misonidazole were conducted; from these results, the protocol was made for phase III study of esophagus cancer, lung cancer, head and neck cancer, uterus cancer, and brain cancer. Brachytherapy using /sup 252/Cf was also developed for locally advanced cancer.

    Purpose To investigate factors associated with female young adult cancer survivors’ (YCS) use of fertility care (FC), including consultation or fertility treatment, after completing their cancer treatment. Methods In this cross-sectional study, females between that ages of 18 and 35 years who had been diagnosed with childhood, adolescent, or young adult cancers completed a 20-min web-based survey that included demographics, reproductive history, use of FC, fertility-related informational needs, and reproductive concerns. Results A total of 204 participants completed the survey. Participants’ mean age was 28.3±4.5 years. Thirty (15%) participants reported using FC after cancer treatment. The majority of participants recalled not receiving enough information about FP options at the time of cancer diagnosis (73%). In multivariable analysis, those with higher concerns about having children because of perceived risk to their personal health (P=0.003) were less likely to report use of FC after cancer treatment. Those who had used FC before cancer treatment (P=0.003) and who felt less fertile than age-matched women (P=0.02) were more likely to use FC after their cancer treatment. Conclusions While most YCS in this cohort believed that they did not receive enough information about fertility and most wanted to have children, the vast majority did not seek FC. The findings of this study offer further evidence of the need for improved education and emotional support regarding reproductive options after cancer treatment is completed. Targeted discussions with YCS about appropriate post-treatment FC options may improve providers’ capacity to help YCS meet their parenthood goals. PMID:26939923

    The suggested classifications of locally recurrent rectal cancer are based on the presence of symptoms and the degree of tumour fixation to the pelvic wall, or, otherwise, account for factor T in the TMN system. Although the results of rectal cancer treatment have improved, which may be attributed to total meso rectal excision and application of perioperative radiotherapy and radiochemotherapy, the ratio of cases of locally recurrent rectal cancer still amount from several to over a dozen percent. Among the available diagnostic methods for detecting locally recurrent rectal cancer after anterior rectal resection, endorectal sonography is of special importance. In the estimation of prognostic factors the lack of vascular invasion in recurrent cancer and the long period between the treatment of primary rectal cancer and the development of recurrence are a sign of good prognosis, while pain prior to recurrence treatment and male sex diminish the chances for cure. Locally recurrent rectal cancer impairs the patient's quality of life in all measurable aspects, but even after complete recovery we observe severe disturbances of sexual activity in most patients, and a number of patients require hygiene pads or suffer from chronic pain. Local recurrence of rectal cancer is more commonly qualified for excision after surgical treatment only, than after preoperative radiotherapy. The probability of total recurrent rectal cancer excision increases when the patient is younger, the primary tumours was less advanced and the first operation was sphincter-sparing surgery. Progress in the surgical treatment of recurrent rectal cancer was brought on by the introduction of the composite musculocutaneous flap to compensate the loss of perineal tissue. The application of intraoperative radiotherapy improves treatment results of recurrent rectal cancer, however at the cost of more frequent, serious postoperative complications and intense pain.

    A multimodal treatment was consisted of intraoperative radiation, external radiation, by-pass operation, chemotherapy and total parenteral nutrition if necessary to cover decreased oral-intake. Thirty-three cases were subjected to this therapy for 6 years. The stage of the tumors varied from a localized tumor in the pancreas to a huge tumor with multiple metastases, though the latter abandoned recently to be contraindication to this therapy. At laparotomy, a high energy electron beam was irradiated to the tumor with a dosage of 3,000 rad using a 20 MeV Betatron. The tumor was carefully prepared in order to avoid irradiating the duodenum and stomach. Choledochojejunostomy and gastrojejunostomy were performed in almost all of patients with cancer of head of pancreas. In some patients, external radiation was added with a dosage of 3,000 rad by linear X-ray. After radiotherapy, chemotherapy employing 5-FU or FT-207 was continued including. The survival time after this therapy was varied mainly according to the stages of the tumor. In patients with multiple metastasis to the liver or peritoneal dissemination, no remarkable effects were obtained by this therapy. On the otherhand, among 14 patients with localized tumor in the pancreas, 7 survived more than one year and the mean survival time of treated patients was nevershorter than that of patients who received resection of the tumor. Most of the treated patients could spend at home until their condition became critical, because by-pass operation could overcome jaundice or the duodenal stenosis and intraoperative radiation could palliate the pain of cancer of pancreas. Tumor effect of intraoperative radiation was confirmed by both of the second laporatomy for twice intraoperative radiation and laparatomy. (author)

    The mainstay of treatment for metastatic colorectal cancer is surgery. Therefore, colorectal cancer metastasis is distinctive, compared to other cancer types in which chemotherapy is the main treatment. Initially, Japan experienced medical druglag compared with western countries. However, the use of oxaliplatin for unresectable recurrent metastatic colorectal cancer became available in Japan, as well as in western countries, in 2005. We have since shifted chemotherapeutic regimens from monotherapy to combination therapy with molecular targeted agents. The combination therapy has rapidly become a standard therapy for unresectable metastatic colorectal cancer, and prognosis has dramatically increased for patients with this condition. Herein, we describe the treatment of liver metastasis of colorectal cancer, and surgery and adjuvant or neoadjuvant therapy options for resectable cancer. Furthermore, we focus on conversion therapy for unresectable cancer.

    Pain is one of the most burdensome symptoms associated with cancer and its treatment, and opioids are the cornerstone of pain management. Opioid therapy is empirically selected, and patients often require adjustments in therapy to effectively alleviate pain or ameliorate adverse drug effects that interfere with quality of life. There are data suggesting CYP2D6 genotype may contribute to inter-patient variability in response to opioids through its effects on opioid metabolism. Therefore, we aim to determine if CYP2D6 genotype-guided opioid prescribing results in greater reductions in pain and symptom severity and interference with daily living compared to a conventional prescribing approach in patients with cancer. Patients with solid tumors with metastasis and a self-reported pain score ≥ 4/10 are eligible for enrollment and randomized to a genotype-guided or conventional pain management strategy. For patients in the genotype-guided arm, CYP2D6 genotype information is integrated into opioid prescribing decisions. Patients are asked to complete questionnaires regarding their pain, symptoms, and quality of life at baseline and 2, 4, 6, and 8 weeks after enrollment. The primary endpoint is differential change in pain severity by treatment strategy (genotype-guided versus conventional pain management). Secondary endpoints include change in pain and symptom interference with daily living. Pharmacogenetic-guided opioid selection for cancer pain management has potential clinical utility, but current evidence is limited to retrospective and observational studies. Precision Medicine Guided Treatment for Cancer Pain is a pragmatic clinical trial that seeks to determine the utility of CYP2D6 genotype-guided opioid prescribing in patients with cancer.

    Purpose: To quantify, using the number needed to treat (NNT) methodology, the benefit of short-term (≤6 months) hormone therapy adjuvant to radiotherapy in the group of patients with early (clinical stage T1-T2c) prostate cancer. Methods and materials: The absolute biochemical control benefit for the use of hormones adjuvant to radiotherapy in early-stage disease was determined by literature review. A model was developed to estimate the utility-adjusted survival detriment due to the side effects of hormone therapy. The NNTs before and after the incorporation of hormone sequelae were computed; the sign and magnitude of the NNTs were used to gauge the effect of the hormones. Results: The absolute NNT analysis, based on summarizing the results of 8 reports including a total of 3652 patients, demonstrated an advantage to the addition of hormones for the general early-stage prostate cancer population as well as for all prognostic groups. After adjustment for hormone-induced functional loss, the advantage of hormones remained considerable in the high- and intermediate-risk groups, with the utility-adjusted NNT becoming weakened in the low-risk group when the utility compromise from complications of hormones was assumed to be considerable. Conclusions: Short-term hormone therapy seems to be beneficial for selected early-stage prostate cancer patients. The advantage seems to be greatest in the intermediate- and high-risk groups; with current follow-up, the side effects of hormones may outweigh their benefit in certain clinical situations in the favorable group. The present investigation demonstrates the significant role of the NNT technique for oncologic and radiotherapeutic management decisions when treatment complications need to be considered and balanced with the beneficial effects of the treatment

    Full Text Available Cancer treatment deserves more research efforts despite intensive conventional treatment modalities for many types of malignancies. Metastasis and resistance to chemotherapy and radiotherapy receive a lot of global research efforts. The current advances in cancer biology may improve targeting the critical metabolic differences that distinguish cancer cells from normal cells. Cancer cells are highly glycolytic for energy production, exhibit the Warburg effect, establish aggressive acidic microenvironment, maintain cancer stem cells, exhibit resistance to chemotherapy, have low antioxidant systems but different ΔΨm (delta psi, mitochondrial transmembrane potential, express P-glycoprotein for multidrug resistance, upregulate glucose transporters and monocarboxylate transporters and are under high steady-state reactive oxygen species conditions. Normal cells differ in all these aspects. Lactate produced through the Warburg effect helps cancer metastasis. Targeting glycolysis reactions for energy production in cancer cells seems promising in decreasing the proliferation and metastasis of cancer cells. 3-bromopyruvate makes use of cancer biology in treating cancer cells, cancer stem cells and preventing metastasis in human cancer as discussed in this review. Updated advances are analyzed here, which include research analysis of background, experience, readings in the field of cancer biology, oncology and biochemistry.

    2016-12-01

    Precision medicine in oncology is the result of an increasing awareness of patient-specific clinical features coupled with the development of genomic-based diagnostics and targeted therapeutics. Companion diagnostics designed for specific drug-target pairs were the first to widely utilize clinically applicable tumor biomarkers (eg, HER2, EGFR), directing treatment for patients whose tumors exhibit a mutation susceptible to an FDA-approved targeted therapy (eg, trastuzumab, erlotinib). Clinically relevant germline mutations in drug-metabolizing enzymes and transporters (eg, TPMT, DPYD) have been shown to impact drug response, providing a rationale for individualized dosing to optimize treatment. The use of multigene expression-based assays to analyze an array of prognostic biomarkers has been shown to help direct treatment decisions, especially in breast cancer (eg, Oncotype DX). More recently, the use of next-generation sequencing to detect many potential "actionable" cancer molecular alterations is further shifting the 1 gene-1 drug paradigm toward a more comprehensive, multigene approach. Currently, many clinical trials (eg, NCI-MATCH, NCI-MPACT) are assessing novel diagnostic tools with a combination of different targeted therapeutics while also examining tumor biomarkers that were previously unexplored in a variety of cancer histologies. Results from ongoing trials such as the NCI-MATCH will help determine the clinical utility and future development of the precision-medicine approach. © 2016, The American College of Clinical Pharmacology.

  20. Does Methodological Guidance Produce Consistency? A Review of Methodological Consistency in Breast Cancer Utility Value Measurement in NICE Single Technology Appraisals.

    Science.gov (United States)

    Rose, Micah; Rice, Stephen; Craig, Dawn

    2017-07-05

    Since 2004, National Institute for Health and Care Excellence (NICE) methodological guidance for technology appraisals has emphasised a strong preference for using the validated EuroQol 5-Dimensions (EQ-5D) quality-of-life instrument, measuring patient health status from patients or carers, and using the general public's preference-based valuation of different health states when assessing health benefits in economic evaluations. The aim of this study was to review all NICE single technology appraisals (STAs) for breast cancer treatments to explore consistency in the use of utility scores in light of NICE methodological guidance. A review of all published breast cancer STAs was undertaken using all publicly available STA documents for each included assessment. Utility scores were assessed for consistency with NICE-preferred methods and original data sources. Furthermore, academic assessment group work undertaken during the STA process was examined to evaluate the emphasis of NICE-preferred quality-of-life measurement methods. Twelve breast cancer STAs were identified, and many STAs used evidence that did not follow NICE's preferred utility score measurement methods. Recent STA submissions show companies using EQ-5D and mapping. Academic assessment groups rarely emphasized NICE-preferred methods, and queries about preferred methods were rare. While there appears to be a trend in recent STA submissions towards following NICE methodological guidance, historically STA guidance in breast cancer has generally not used NICE's preferred methods. Future STAs in breast cancer and reviews of older guidance should ensure that utility measurement methods are consistent with the NICE reference case to help produce consistent, equitable decision making.

    Objective To study the comorbidity of common mental disorders (CMDs) and cancer, and the mental health treatment gap among community residents with active cancer, cancer survivors and cancer-free respondents in 13 high- and 11 low-middle income countries. Methods Data were derived from the World Mental Health Surveys (N=66,387; n=357 active cancer, n=1,373 cancer survivors, n=64,657 cancer free respondents). The WHO/Composite International Diagnostic Interview was used in all surveys to estimate CMDs prevalence rates. Respondents were also asked about mental health service utilization in the preceding 12 months. Cancer status was ascertained by self-report of physician’s diagnosis. Results Twelve month prevalence rates of CMDs were higher among active cancer (18.4% SE=2.1) than cancer free respondents (13.3%, SE=0.2) adjusted for socio-demographic confounders and other lifetime chronic conditions (Adjusted Odds Ratio (AOR)=1.44 95% CI 1.05–1.97). CMD rates among cancer survivors (14.6% SE=0.9) compared with cancer-free respondents did not differ significantly (AOR=0.95 95% CI 0.82–1.11). Similar patterns characterized high and low-middle income countries. Of respondents with active cancer who had CMD in the preceding 12 months 59% sought services for mental health problems (SE=5.3). The pattern of service utilization among people with CMDs by cancer status (highest among persons with active cancer, lower among survivors and lowest among cancer-free respondents) was similar in high- (64.0% SE=6.0, 41.2% SE=3.0, 35.6% SE=0.6) and low-middle income countries (46.4% SE=11.0, 22.5% SE=9.1, 17.4% SE=0.7). Conclusions Community respondents with active cancer have relatively higher CMD rates and relatively high treatment gap. Comprehensive cancer care should consider both factors. PMID:23983079

    Full Text Available Hari Deshpande1,3, Vicky Marler3, Julie Ann Sosa2,31Department of Medicine, 2Department of Surgery, Yale University School of Medicine, 3Yale Cancer Center, New Haven, CT, USAAbstract: Vandetanib (ZD6474 became the first systemic agent to be approved for the treatment of metastatic or locally advanced medullary thyroid cancer. It was a proof of principle, because it is an orally bioavailable medication that targets the growth factors felt to be important in the pathogenesis of this disease, ie, the rearranged during transfection proto-oncogene and vascular endothelial growth factor receptor. It was tested initially in two Phase II studies at doses of 100 mg and 300 mg daily. Although activity was seen at both doses, the higher dose was chosen for a randomized, placebo-controlled Phase II study. This trial, which accrued more than 300 patients, showed a statistically significant benefit for the group taking vandetanib compared with those taking placebo medication. Progression-free survival for the vandetanib arm has not been reached, compared with 19 months for the placebo arm. The main toxicity appears to be diarrhea, although some patients experienced significant side effects, including torsades de pointes and sudden cardiac death. Therefore, it is now necessary for practitioners to enroll in a Risk Evaluation Mitigation Strategy before being allowed to prescribe this medication, to reduce the risk of serious side effects occurring.Keywords: ZD6474, medullary thyroid cancer, vandetanib

  3. Carbon Nanomaterials for Breast Cancer Treatment

    Full Text Available Currently, breast cancer is considered as a health problem worldwide. Furthermore, current treatments neither are capable of stopping its propagation and/or recurrence nor are specific for cancer cells. Therefore, side effects on healthy tissues and cells are common. An increase in the efficiency of treatments, along with a reduction in their toxicity, is desirable to improve the life quality of patients affected by breast cancer. Nanotechnology offers new alternatives for the design and synthesis of nanomaterials that can be used in the identification, diagnosis, and treatment of cancer and has now become a very promising tool for its use against this disease. Among the wide variety of nanomaterials, the scientific community is particularly interested in carbon nanomaterials (fullerenes, nanotubes, and graphene due to their physical properties, versatile chemical functionalization, and biocompatibility. Recent scientific evidence shows the potential uses of carbon nanomaterials as therapeutic agents, systems for selective and controlled drug release, and contrast agents for diagnosing and locating tumors. This generates new possibilities for the development of innovative systems to treat breast cancer and can be used to detect this disease at much earlier stages. Thus, applications of carbon nanomaterials in breast cancer treatment are discussed in this article.

    The nature-based and nontoxic image makes application of unproven methods in oncology attractive in contrast to application of a mechanized scientific medicine. The application frequency of these treatments ranges from 10% to greater than 60%. Increasingly, the promoters try to create a scientific impression through a pseudologic cancer theory, a harmless diagnostic test, and a holistic treatment of every cancer. Of the big variety of unproven methods, which are summarized in 11 groups in this review, the following are discussed: anthroposophic and other mistletoe preparations; homeopathy; Maharishi Ayur-Veda; unproven anticancer diets; orthomolecular medicine, including ascorbic acid; and methods supposedly stimulating unspecific and specific defense mechanisms. In conclusion, physicians should beware of and have knowledge of currently used unproven cancer treatments for epidemiologic, social, economic, and scientific reasons.

    Over 91,000 new cases of gynecological cancers are expected to be diagnosed in 2013 in the US alone. As cancer detection technology and treatment options improve, the number of working-age cancer survivors continues to grow. To describe US gynecological cancer survivors' perceptions of the effects of cancer and treatment on their job tasks. 104 adult gynecological cancer survivors who were working at the time of their cancer diagnosis, treated at a University-based women's health clinic, diagnosed in the previous 24 months, and spoke English. Women completed written surveys to describe their work experiences following diagnosis. Clinical characteristics were obtained through medical record review. Descriptive statistics and cross tabulations were performed to describe characteristics and associations. Fifteen percent of women had chemotherapy and radiation treatment; 48% had only chemotherapy, 9% only radiation therapy, and 28% had neither. Survivors described the frequency of performing seven job tasks, such as 'intense concentration', 'analyzing data', and 'lifting heavy loads.' Women who had undergone radiation treatment were more likely to indicate limitations for physical tasks; women undergoing chemotherapy were more likely to report limitations in more analytic tasks. Only 29% of women noted an employer-based policy facilitated their return-to-work process. Cancer and treatment have important effects on job performance and may vary by type of treatment. Employer-based policies focusing on improved communication and work accommodations may improve the return to work process.

    2014-01-01

    The majority of children, adolescents, and young adults diagnosed with cancer today will become long-term survivors. The threat to fertility that cancer treatments pose to young patients cannot be prevented in many cases, and thus research into methods for fertility preservation is developing, aiming at offering cancer patients the ability to have biologically related children in the future. This paper discusses the current status of fertility preservation methods when infertility risks are related to surgical oncologic treatments, radiation therapy, or chemotherapy. Several scientific groups and societies have developed consensus documents and guidelines for fertility preservation. Decisions about fertility and imminent potentially gonadotoxic therapies must be made rapidly. Timely and complete information on the impact of cancer treatment on fertility and fertility preservation options should be presented to all patients when a cancer treatment is planned.

    Purpose: To estimate actual utilization rates of radiation therapy (RT) in Norway, describe time trends (1997-2010), and compare these estimates with corresponding optimal RT rates. Methods and Materials: Data from the population-based Cancer Registry of Norway was used to identify all patients diagnosed with cancer and/or treated by RT for cancer in 1997-2010. Radiation therapy utilization rates (RURs) were calculated as (1) the proportion of incident cancer cases who received RT at least once within 1 year of diagnosis (RUR 1Y ); and (2) the proportion who received RT within 5 years of diagnosis (RUR 5Y ). The number of RT treatment courses per incident cancer case (TCI) was also calculated for all cancer sites combined. The actual RURs were compared with corresponding Australian and Canadian epidemiologic- and evidence-based model estimates and criterion-based benchmark estimates of optimal RURs. The TCIs were compared with TCI estimates from the 1997 Norwegian/National Cancer Plan (NCP). Joinpoint regression was used to identify changes in trends and to estimate annual percentage change (APC) in actual RUR 1Y and actual TCI. Results: The actual RUR 5Y (all sites) increased significantly to 29% in 2005 but still differed markedly from the Australian epidemiologic- and evidence-based model estimate of 48%. With the exception of RUR 5Y for breast cancer and RUR 1Y for lung cancers, all actual RURs were markedly lower than optimal RUR estimates. The actual TCI increased significantly during the study period, reaching 42.5% in 2010, but was still lower than the 54% recommended in the NCP. The trend for RUR 1Y (all sites) and TCI changed significantly, with the annual percentage change being largest during the first part of the study period. Conclusions: Utilization rates of RT in Norway increased after the NCP was implemented and RT capacity was increased, but they still seem to be lower than optimal levels

    Cancer screening reduces mortality rates for breast, cervical, and colon cancer. Yet cancer screening rates for Latina women are lower than for non-Latino Whites, and below Healthy People 2020 goals. Additionally, Latinos face many health care access barriers. This study examined health care access and utilization in relation to cancer screening among low-income Latina women recruited from a high-risk area and enrolled in a navigation-plus-education intervention. Latina women considered rarely or never screened for breast, cervical, or colorectal cancer were recruited from community-based organizations and events (N = 691). We gathered self-reported survey data on insurance status, usual source of care, health care utilization, and cancer screening behavior. We conducted multivariable logistic regression models to estimate odds ratios of receipt of at least one cancer screening test. Overall, 28% of women received at least one cancer screening test. Results indicated that women without insurance (odds ratio [OR] = 2.08; confidence interval [CI] = 1.09, 3.98) and without a doctor's visit in the past year (OR = 2.02; CI = 1.28, 3.18), compared with their counterparts, had greater odds of receiving at least one screening test. Findings highlight the continued need to explore ways to support uninsured individuals' screening efforts and further investigate barriers among insured women who are not up-to-date with screenings.

    2016-01-01

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

    3DCRT treatments are the most commonly used techniques in the treatment of lung and breast cancers. The purpose of this study was to perform the BMOA of the 3DCRT plans designed for the treatment of breast and lung cancers utilizing HART program (Med. Phys. 36, p.2547(2009)). The BMOA parameters include normal tissue complication probability (NTCP), tumor control probability (TCP), and the complication-free tumor control probability (P+). The 3DCRT plans were designed for (i) the palliative treatment of 8 left lung cancer patients (CPs) at early stage (m=8), (ii) the curative treatment of 8 left lung CPs at stages II and III (k=8), and (iii) the curative treatment of 8 left breast CPs (n=8). The NTCPs were noticeably small (esophagus in lung CPs (k=8). Assessments of the TCPs and P+s also indicated good improvements in local tumor control in all plans. Homogeneous target coverage and improved dose conformality were the major advantages of such techniques in the treatment of breast cancer. These achievements support the efficacy of the 3DCRT techniques for the efficient treatment of various types of cancer.

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

Schmidt College of Medicine, Florida Atlantic University, FL, 3North Main Radiation Oncology, Warren Alpert School of Medicine, Brown University, RI, USA Abstract: Nonmelanoma skin cancer (NMSC is an increasing health care issue in the United States, significantly affecting quality of life and impacting health care costs. Radiotherapy has a long history in the treatment of NMSC. Shortly after the discovery of X-rays and 226Radium, physicians cured patients with NMSC using these new treatments. Both X-ray therapy and brachytherapy have evolved over the years, ultimately delivering higher cure rates and lower toxicity. Electronic brachytherapy for NMSC is based on the technical and clinical data obtained from radionuclide skin surface brachytherapy and the small skin surface applicators developed over the past 25 years. The purpose of this review is to introduce electronic brachytherapy in the context of the history, data, and utilization of traditional radiotherapy and brachytherapy.

    To explore the relationship between insurance status and differences in treatment and survival of testicular cancer patients. The Surveillance, Epidemiology, and End Results (SEER) database was utilized for this study. Between 2007 and 2011, 5986 testicular cancer patients were included in the SEER database. Patients were classified into nonseminoma and seminoma groups. We compared mortality rates, metastasis (M+) at diagnosis, and rates of adjuvant treatments between the uninsured (UI) and insured (I) populations. Overall, 2.64% of UI vs 1.36% of I died from testicular cancer (P = .025) and 16.73% of UI vs 10.52% of I had M+ at diagnosis (P testicular cancer (P = .326) and 25.92% of UI vs 18.46% of I had M+ at diagnosis (P = .0007). Also 17.28% of UI vs 20.88% of I had retroperitoneal lymph node dissection (RPLND; P = .1). In the seminoma group, 1.06% of UI vs 0.33% of I died from testicular cancer (P = .030) and 7.43% of UI vs 4.81% of I had M+ at diagnosis (P = .029). Also 34.75% of UI vs 48.4% of I received adjuvant radiation (P = .0083). The lack of health insurance predicted poor survival after adjusting for tumor stage, receiving adjuvant radiation or RPLND. UI testicular cancer patients present with more advanced cancer stages and have higher mortality rates than I patients. UI seminoma patients received less adjuvant radiation. This may be related to lack of access to care or more advanced cancer stage at diagnosis. Copyright © 2016. Published by Elsevier Inc.

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

Our objective was to examine the care-delivering processes in health care during the last months of life with real-life data of Swiss cancer patients. Patients and methods: The study population consisted of adult decedents in 2014 who were insured at Helsana Group. Data on the final cause of death were provided additionally by the Swiss Federal Statistical Office. Of the 10,275 decedents, 2,710 (26.4% died of cancer. Intensity of treatment and health care utilization (including transitions at their end-of-life were examined. Intensity measures included the following: last dose of chemotherapy within 14 days of death, a new chemotherapy regimen starting <30 days before death, more than one hospital admission or spending >14 days in hospital in the last month, death in an acute care hospital, more than one emergency visit and ≥1 intensive care unit admission in the last month of life. Results: In the last 6 months of life, 89.5% of cancer patients had ≥1 transition, with 87.2% being hospitalized. Within 30 days before death, 64.2% of the decedents had ≥1 intensive treatment, whereby 8.9% started a new chemotherapy. In the multinomial logistic regression model, older age, higher density of nursing home beds and home care nurses were associated with a decrease, while living in the Italian- or French-speaking part of Switzerland was associated with an increase in intensive care. Conclusion: Swiss cancer patients insured by Helsana Group experience a considerable number of transitions and intensive treatments at the end-of-life, whereby treatment intensity

    Full Text Available BACKGROUND: Despite the high cost of initial cancer care, that is, care in the first year after diagnosis, limited information is available for specific categories of cancer-related costs, especially costs for specific services. This study purposed to identify causes of change in cancer treatment costs over time and to perform trend analyses of the percentage of cancer patients who had received a specific treatment type and the mean cost of care for patients who had received that treatment. METHODOLOGY/PRINCIPAL FINDINGS: The analysis of trends in initial treatment costs focused on cancer-related surgery, chemotherapy, radiation therapy, and treatments other than active treatments. For each cancer-specific trend, slopes were calculated for regression models with 95% confidence intervals. Analyses of patients diagnosed in 2007 showed that the National Health Insurance (NHI system paid, on average, $10,780 for initial care of a gastric cancer patient and $10,681 for initial care of a lung cancer patient, which were inflation-adjusted increases of $6,234 and $5,522, respectively, over the 1996 care costs. During the same interval, the mean NHI payment for initial care for the five specific cancers increased significantly (p<0.05. Hospitalization costs comprised the largest portion of payments for all cancers. During 1996-2007, the use of chemotherapy and radiation therapy significantly increased in all cancer types (p<0.05. In 2007, NHI payments for initial care for these five cancers exceeded $12 billion, and gastric and lung cancers accounted for the largest share. CONCLUSIONS/SIGNIFICANCE: In addition to the growing number of NHI beneficiaries with cancer, treatment costs and the percentage of patients who undergo treatment are growing. Therefore, the NHI must accurately predict the economic burden of new chemotherapy agents and radiation therapies and may need to develop programs for stratifying patients according to their potential benefit

    Incidence of breast cancer in pregnancy is increasing due to trend of postponing child-bearing to later age. Breast cancer diagnosed during lactation has different biologic behaviour and worse prognosis than when diagnosed during pregnancy. Pregnancy does not constitute a negative prognostic factor per se for outcomes of breast cancer in pregnancy, therefore breast cancer should be treated while containing pregnancy. Pregnancy should not delay treatment. Therapy should follow standard procedures as closely as possible, though with different timing of treatment modalities. Experienced multidisciplinary team is crucial for achieving good treatment results and involvement of an informed patient in decision-making is a must. Properly managed treatment during pregnancy does not carry detrimental effect on development and well-being of children. (author)

    Cancer pain is difficult to treat, often requiring a multimodal approach. While medication management remains the mainstay for the treatment of cancer pain, medications are often associated with undesired side effects. Transcutaneous electrical nerve stimulation (TENS) provides a potential adjunctive method for treating cancer pain with minimal side effects. Few studies have been performed evaluating the efficacy of TENS on cancer pain. We sought to examine the usefulness of TENS on all cancer patients and to specifically look at the use of TENS as a goal-directed therapy to improve functionality. Retrospective cohort study. Since 2008, patients with chronic cancer pain and on multimodal pain regimens were trialed with TENS. Those patients who showed an improvement in pain symptoms or severity were educated about and provided with a TENS unit for use at home. Pain symptoms and scores were monitored with the visual analog scale (VAS), the numerical rating pain (NRP) scale, and Short-Form McGill Questionnaire at the start of TENS treatment and at 2 months follow-up. TENS proved beneficial in 69.7% of patients over the course of 2 months. In TENS responsive patients, VAS scores decreased by 9.8 on a 0-100 mm scale (P TENS provides a beneficial adjunct for the treatment of cancer pain, especially when utilized as a goal-directed therapy.

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

    Hyperthermia is an established anti-cancer treatment but is limited by tolerance of adjacent normal tissues. Parenteral administration of gold nanorods (NRs) as a photosensitizer amplifies the effects of hyperthermia treatment while sparing normal tissues. This therapy is well tolerated and has demonstrated anti-tumor effects in mouse models. The purpose of this phase 1 study was to establish the safety and observe the anti-tumor impact of gold NR enhanced (plasmonic) photothermal therapy (PPTT) in client owned canine patients diagnosed with spontaneous neoplasia. Seven dogs underwent gold NR administration and subsequent NIR PPTT. Side effects were mild and limited to local reactions to NIR laser. All of the dogs enrolled in the study experienced stable disease, partial remission or complete remission. The overall response rate (ORR) was 28.6% with partial or complete remission of tumors at study end. PPTT utilizing gold nanorod therapy can be safely administered to canine patients. Further studies are needed to determine the true efficacy in a larger population of canine cancer patients and to and identify those patients most likely to benefit from this therapy.

    The aim of our study was to evaluate the relationship between routine treatment of periodontal disease (PD) and the subsequent risks for cancers in Taiwan. Study participants were selected from the Taiwan National Health Insurance (NHI) system database. The PD with a routine treatment cohort contained 38 902 patients. For each treatment cohort participant, two age- and sex-matched comparison (control) cohort participants were randomly selected. Cox's proportional hazards regression analysis was used to estimate the effects of PD with treatment on the subsequent risk of cancer. The overall risk of developing cancer was significantly lower in the treatment cohort than in the patients without treatment (adjusted Hazard ratio = 0.72, 95% confidence interval = 0.68-0.76). The risks of developing most gastrointestinal tract, lung, gynecological and brain malignancies were significantly lower in the treatment cohort than in the comparison cohort. In contrast, the risks of prostate and thyroid cancers were significantly higher in the treatment cohort than in the comparison cohort. Our findings suggest that PD with treatment is associated with a significantly reduced overall risk of cancer and reduced risks of certain types of cancers. © The Author 2014.

    The incidence of lung cancer is increasing with longer life expectancy. Refusal of active treatment for cancer is prone to cause patients to experience more severe symptoms and shorten survival. The purpose of this study was to define the factors related to refusal or abandonment of active therapy in lung cancer. We retrospectively reviewed the data of 617 patients from medical records from 2010 to 2014. Two groups were formed: 149 patients who refused anti-cancer treatment and allowed only palliative care were classified into the non-treatment group, while the remaining 468 who received anti-cancer treatment were classified into the treatment group. The groups differed significantly in age, employment, relationship status, number of offspring, educational status, body mass index, presence of chest and systemic symptoms, Charlson Comorbidity Index, Eastern Cooperative Oncology Group score, and tumor node metastasis stage ( P refusal of cancer treatment. Individual factors, such as old age, low educational status, low weight, and poor performance status can influence refusal of cancer treatment in patients with lung cancer, and should be considered prior to consultation with patients. © 2017 The Authors.

    Around 27,000 new cases of prostate cancer are diagnosed every year in Spain and 5400 die from this disease. Radiotherapy (RT), alone or combined, has proven to be effective as initial treatment in patients with localized disease. Our objective was to evaluate the use of external beam RT (EBRT) in our region, comparing the indication rate and irradiation rate and examining variability in its application among hospitals. We conducted a review of RT guidelines and indication studies for prostate cancer (% expected irradiation). Data were gathered from all twelve public healthcare centers in Andalusia (Spain) on RT-treated prostate cancer patients during 2013 (% actual irradiation) and from nine of the centers on RT discharge reports. Information was classified according to type of hospital, tumor risk category and RT treatment (technique, dosage, volume, toxicity). The estimated RT rate was 67 % (1289/1917), 43 % were aged > 70 years, 44.7 % had ECOG performance status of 0); 44.7 % had high-risk tumors; 57 % underwent RT associated with hormone therapy; 70 % of patients receiving RT were treated with 3D planning (30 % IGRT); and doses were 70-76 Gy in 70 % of cases and >76 Gy in 10.7 %. Acute gastrointestinal and genitourinary toxicities were < grade 2 in 79 and 89 % of patients, respectively. An irradiation rate significantly below the mean for the study was found in four provinces. There was a significant difference among provinces in the distribution of risk groups. Underutilization of EBRT was estimated to be around 30 % in prostate cancer patients, with an elevated variability in irradiation rates among hospitals related to differences in available technology and in the distribution of patients with different risk levels. These data should be a matter of concern to regional health managers, given the negative and measurable impact on the survival of patients.

    The benefits associated with some cancer treatments do not come without risk. A serious side effect of some common cancer treatments is cardiotoxicity. Increased recognition of the public health implications of cancer treatment-induced cardiotoxicity has resulted in a proliferation of systematic reviews in this field to guide practice. Quality appraisal of these reviews is likely to limit the influence of biased conclusions from systematic reviews that have used poor methodology related to clinical decision-making. The aim of this meta-review is to appraise and synthesise evidence from only high quality systematic reviews focused on the prevention, detection or management of cancer treatment-induced cardiotoxicity. Using Cochrane methodology, we searched databases, citations and hand-searched bibliographies. Two reviewers independently appraised reviews and extracted findings. A total of 18 high quality systematic reviews were subsequently analysed, 67 % (n = 12) of these comprised meta-analyses. One systematic review concluded that there is insufficient evidence regarding the utility of cardiac biomarkers for the detection of cardiotoxicity. The following strategies might reduce the risk of cardiotoxicity: 1) The concomitant administration of dexrazoxane with anthracylines; 2) The avoidance of anthracyclines where possible; 3) The continuous administration of anthracyclines (>6 h) rather than bolus dosing; and 4) The administration of anthracycline derivatives such as epirubicin or liposomal-encapsulated doxorubicin instead of doxorubicin. In terms of management, one review focused on medical interventions for treating anthracycline-induced cardiotoxicity during or after treatment of childhood cancer. Neither intervention (enalapril and phosphocreatine) was associated with statistically significant improvement in ejection fraction or mortality. This review highlights the lack of high level evidence to guide clinical decision-making with respect to the detection

    The paper establishes the utility of the fiber- optic bronchoscopy (FOB) studies performed in patients with esophageal cancer (EC) and confirm the possibility of tracheo-bronchial compromise. We carry out a descriptive study in 226 patients with esophageal cancer during 1991 to 1996 in the Instituto Nacional de Cancerologia of Colombia (INC). We excluded the patients with previous treatments: radiotherapy or surgery, and others primary cancers with metastases on the esophagus. We analyzed gastric, intestinal and general symptoms, smoking habits, primary cancer location, histological types, radiologic findings, fob findings, micro and macroscopes, and results of the samples: transbronchial, endobronchial biopsies, bronchi alveolar lavage and brush. We included 158 patients, 110 male and 48 female, with age between 32 and 83 years, symptoms duration average of 5,2 months. The most significant were cough, dysphonia and sputum. The location of EC was statistics significance only in the upper third escamocelular type. The significant radiological findings were: parenchymal nodules and interstitial infiltrates, the significant fob findings were: fistula endobronchial infiltration endobronchial mass and vocal cords palsy. The zones with more compromise were trachea, principal bronchi and vocal cords. Only 17 patients were positives in the samples; comparing the histopathologic findings (biopsies) as the gold standard with fob findings the sensitivity was 100%, specificity 35%, positive predictive value 15.6% and negative predictive value 100%.

Later linear accelerators with more accessories were developed and are now used for the advanced treatments like IMRT, IGRT etc. Gammaknife, Gyroknife and supergamma machines using 60 Co have also taken roots for the treatment of cancer. The use of 60 Co in the treatment of cancer is expected to continue for some more time to come. (author)

  11. Targeting Stromal-Cancer Cell Crosstalk Networks in Ovarian Cancer Treatment

    Directory of Open Access Journals (Sweden)

    2016-01-01

    Full Text Available Ovarian cancer is a histologically, clinically, and molecularly diverse disease with a five-year survival rate of less than 30%. It has been estimated that approximately 21,980 new cases of epithelial ovarian cancer will be diagnosed and 14,270 deaths will occur in the United States in 2015, making it the most lethal gynecologic malignancy. Ovarian tumor tissue is composed of cancer cells and a collection of different stromal cells. There is increasing evidence that demonstrates that stromal involvement is important in ovarian cancer pathogenesis. Therefore, stroma-specific signaling pathways, stroma-derived factors, and genetic changes in the tumor stroma present unique opportunities for improving the diagnosis and treatment of ovarian cancer. Cancer-associated fibroblasts (CAFs are one of the major components of the tumor stroma that have demonstrated supportive roles in tumor progression. In this review, we highlight various types of signaling crosstalk between ovarian cancer cells and stromal cells, particularly with CAFs. In addition to evaluating the importance of signaling crosstalk in ovarian cancer progression, we discuss approaches that can be used to target tumor-promoting signaling crosstalk and how these approaches can be translated into potential ovarian cancer treatment.

    AIMS: We will examine the latest advances in genomic and proteomic laboratory technology. Through an extensive literature review we aim to critically appraise those studies which have utilized these latest technologies and ascertain their potential to identify clinically useful biomarkers. METHODS: An extensive review of the literature was carried out in both online medical journals and through the Royal College of Surgeons in Ireland library. RESULTS: Laboratory technology has advanced in the fields of genomics and oncoproteomics. Gene expression profiling with DNA microarray technology has allowed us to begin genetic profiling of colorectal cancer tissue. The response to chemotherapy can differ amongst individual tumors. For the first time researchers have begun to isolate and identify the genes responsible. New laboratory techniques allow us to isolate proteins preferentially expressed in colorectal cancer tissue. This could potentially lead to identification of a clinically useful protein biomarker in colorectal cancer screening and treatment. CONCLUSION: If a set of discriminating genes could be used for characterization and prediction of chemotherapeutic response, an individualized tailored therapeutic regime could become the standard of care for those undergoing systemic treatment for colorectal cancer. New laboratory techniques of protein identification may eventually allow identification of a clinically useful biomarker that could be used for screening and treatment. At present however, both expression of different gene signatures and isolation of various protein peaks has been limited by study size. Independent multi-centre correlation of results with larger sample sizes is needed to allow translation into clinical practice.

    Organ transplant recipients have an up to 250-times higher risk to develop skin cancer. This article evaluated the utilisation of skin cancer screening and the treatment costs for skin cancer in organ transplant recipients. Patients of the health insurance AOK Bremen/Bremerhaven had been identified and the need for skin cancer prevention trainings was derived. The number of organ transplant recipients (ICD code Z94.0-4) with and without any history of skin cancer (ICD code C43/C44), the utilisation of dermatologic health care services, and the costs for treatments with the diagnosis Z94.0-4 with and without C43/C44 were evaluated. The analyses were carried out for the period from 2009-2014 by using the accounting systems of the AOK. Between 2009 and 2014, 231 organ transplant recipients had been recorded. By mid-2014, 20% of these insured persons developed skin cancer and the mean incidence was 2.76% per year. On average, 43% of these patients were seen by a dermatologist at least once a year, whereby only 15% of the organ transplant recipients participated in the annual skin cancer screening. In 29% of the patients without any history of skin cancer, a skin examination was never performed by a dermatologist or a general practitioner. In all, 17 inpatient cases of organ transplant recipients with the primary diagnosis C43/C44 were analyzed. This resulted in total costs of 54,707 € (on average about 3200 € per case). The increased incidence of skin cancer and the associated treatment costs indicate the need for skin cancer prevention training.

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

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

    Background Following completion of substance use treatment, it is crucial for patients to continue to utilize skills learned in treatment for optimal treatment outcomes. Mobile applications (apps) on smartphones offer a unique platform to promote utilization of evidence-based skills following completion of substance use treatment. Despite the promise of mobile apps and smartphones for treatment delivery, it remains unknown whether patients in substance use treatment in the United States have access to smartphones and utilize mobile apps on smartphones. The present study sought to determine smartphone utilization among individuals enrolled in one residential substance use treatment center in the U.S catering specifically to low-income adults. Methods Participants included 251 individuals at a residential substance use treatment center in Washington DC admitted to the center between March, 2014 and January, 2015. During the intake process, participants completed interviewer-administered demographics and psychiatric questionnaires as well as a self-report of technology utilization. Results Results indicated that the majority of patients in this residential substance use treatment center owned mobile phones prior to treatment entry (86.9%) and expected to own mobile phones after leaving treatment (92.6%). Moreover, the majority of these phones were (68.5%) or will be smartphones (72.4%) on which patients reported utilizing mobile applications (Prior to treatment: 61.3%; Post treatment: 64.3%) and accessing the internet (Prior to treatment: 61.3%; Post treatment: 65.9%). Conclusions Mobile phone and smartphone ownership among this sample were comparable to ownership among U.S. adults broadly. Findings suggest that smartphones and mobile apps may hold clinical utility for fostering continued use of treatment skills following substance use treatment completion. PMID:26231698

    2014-01-01

    The aim of this study was to evaluate the utility of an Australasian registry ('the Registry') for children undergoing radiation treatment (RT). Children under the age of 16years who received a course of radiation between January 1997 and December 2010 and were enrolled on the Registry form the subjects of this study. A total of 2232 courses of RT were delivered, predominantly with radical intent (87%). Registrations fluctuated over time, but around one-half of children diagnosed with cancer undergo a course of RT. The most prevalent age range at time of RT was 10–15years, and the most common diagnoses were central nervous system tumours (34%) and acute lymphoblastic leukaemia (20%). The Registry provides a reflection of the patterns of care of children undergoing RT in Australia and a mechanism for determining the resources necessary to manage children by RT (human, facilities and emerging technologies, such as proton therapy). It lacks the detail to provide information on radiotherapy quality and disease outcomes which should be the subject of separate audit studies. The utility of the Registry has been hampered by its voluntary nature and varying needs for consent. Completion of registry forms is a logical requirement for inclusion in the definition of a subspecialist in paediatric radiation oncology.

    Esophageal cancer is the eighth most common form of cancer worldwide. The treatments for esophageal cancer depend on its etiology. For mucosal cancer, endoscopic mucosal resection and endoscopic submucosal dissection are standard, while for locally advanced cancer, esophagectomy remains the mainstay. The three most common techniques for thoracic esophagectomy are the transhiatal approach, the Ivor Lewis esophagectomy (right thoracotomy and laparotomy), and the McKeown technique (right thoracotomy followed by laparotomy and neck incision with cervical anastomosis). Surgery for carcinoma of the cervical esophagus requires an extensive procedure with laryngectomy in many cases. When the tumor is more advanced, neoadjuvant chemotherapy or neoadjuvant chemoradiotherapy is added. The theoretical advantages of adding chemotherapy to the treatment of esophageal cancer are potential tumor down-staging prior to surgery, as well as targeting micrometastases and, thus, decreasing the risk of distant metastasis. Cisplatin- and 5-fluorouracil-based regimes are used worldwide. Chemoradiotherapy is the standard for unresectable esophageal cancer and could also be considered as an option for resectable tumors. For patients who are medically or technically inoperable, concurrent chemoradiotherapy should be the standard of care. Although neoadjuvant chemoradiotherapy followed by surgery or salvage surgery after definitive chemoradiotherapy is a practical treatment; judicious patient selection is crucial. It is important to have a thorough understanding of these therapeutic modalities to assist in this endeavor. (author)

    The purpose of this study was to demonstrate the potential utility of megavoltage fan-beam computed tomography (MV-FBCT) for treatment planning in a patient undergoing helical tomotherapy for nasopharyngeal carcinoma in the presence of extensive dental artifact. A 28-year-old female with locally advanced nasopharyngeal carcinoma presented for radiation therapy. Due to the extensiveness of the dental artifact present in the oral cavity kV-CT scan acquired at simulation, which made treatment planning impossible on tomotherapy planning system, MV-FBCT imaging was obtained using the HI-ART tomotherapy treatment machine, with the patient in the treatment position, and this information was registered with her original kV-CT scan for the purposes of structure delineation, dose calculation, and treatment planning. To validate the feasibility of the MV-FBCT-generated treatment plan, an electron density CT phantom (model 465, Gammex Inc., Middleton, WI) was scanned using MV-FBCT to obtain CT number to density table. Additionally, both a 'cheese' phantom (which came with the tomotherapy treatment machine) with 2 inserted ion chambers and a generic phantom called Quasar phantom (Modus Medical Devices Inc., London, ON, Canada) with one inserted chamber were used to confirm dosimetric accuracy. The MV-FBCT could be used to clearly visualize anatomy in the region of the dental artifact and provide sufficient soft-tissue contrast to assist in the delineation of normal tissue structures and fat planes. With the elimination of the dental artifact, the MV-FBCT images allowed more accurate dose calculation by the tomotherapy system. It was confirmed that the phantom material density was determined correctly by the tomotherapy MV-FBCT number to density table. The ion chamber measurements agreed with the calculations from the MV-FBCT generated phantom plan within 2%. MV-FBCT may be useful in radiation treatment planning for nasopharyngeal cancer patients in the setting of extensive

    Venous thromboembolism (VTE) is a common complication of cancer. Clinical practice guidelines recommend low-molecular-weight heparin (LMWH) for treatment of cancer-associated VTE, but it is unclear how frequently these are followed. This study assessed anticoagulation treatment patterns for VTE in newly diagnosed cancer patients in the United States. MarketScan® claims records of more than 80 million insured members between January 1, 2009 and July 31, 2014 were retrospectively analyzed. Subjects were included if they were 18years of age or older, and had a diagnosis of cancer (9 solid tumor types) and VTE. Data were included for LMWH, warfarin, and other anticoagulants (fondaparinux and direct oral anticoagulants [DOACs]). Patients with anticoagulant treatment prior to cancer diagnosis were excluded. VTE developed in 6.2% of cancer patients (median, 181days after cancer diagnosis). VTE rates were highest for pancreatic (17.5%) and lung (12.6%) cancer and lowest for breast (4.2%) and prostate (4.1%) cancer. For patients for whom outpatient prescription data were available, warfarin was most commonly used (50.0%), followed by LMWH (40.0%) and other anticoagulants (10.0%). Over 6months, 13% of patients who initiated injectable anticoagulants remained on them compared with 30% of those who initiated oral anticoagulants. More patients switched from LMWH to warfarin and other anticoagulants (44%) versus those who switched from warfarin (28%). Warfarin was the most utilized anticoagulant for cancer-associated VTE despite guideline recommendations for LMWH. More patients remained on oral versus injectable agents, which may be related to self-injection burden and costs. Copyright © 2016 Elsevier Ltd. All rights reserved.

  6. Early breast cancer: diagnosis, treatment and survivorship.

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

    The subjects were 30 multiple primary cancers (out of 2,169 oral squamous cell carcinoma including lip cancers), which were treated at the Division of Head and Neck, Cancer Institute Hospital. Seven synchronous carcinomas and 23 metachronous cases were seen. The most common site of the primary cancer was the tongue. Surgical treatment was performed for the first treatment in 5 cases of the 7 synchronous cancers. On the other hand, radical treatment was performed in 11 cases of the 23 metachronous cancers. Fourteen of the 18 cases were treated by surgical treatment and controlled. It is suggested that surgical treatment is the most effective for oral multiple primary cancers. (author)

    Antiestrogen resistance is a major clinical problem in current breast cancer treatment. Therefore, biomarkers and new treatment options for antiestrogen-resistant breast cancer are needed. In this study, we investigated whether antiestrogen‑resistant breast cancer cell lines have increased...... sensitivity to carboplatin, as it was previously shown with cisplatin, and whether low Bcl-2 expression levels have a potential value as marker for increased carboplatin sensitivity. Breast cancer cells resistant to the pure antiestrogen fulvestrant, and two out of four cell lines resistant...... to the antiestrogen tamoxifen, were more sensitive to carboplatin treatment compared to the parental MCF-7 cell line. This indicates that carboplatin may be an advantageous treatment in antiestrogen‑resistant breast cancer; however, a marker for increased sensitivity would be needed. Low Bcl-2 expression...

    Cyclo-oxygenase-2 (COX-2), an inducible enzyme expressed in areas of inflammation, is a target of interest for colorectal cancer therapy. Currently, the predictive significance of COX-2 in colorectal cancer remains unclear. Tissue microarrays were constructed using 118 colon cancer and 85 rectal cancer specimens; 44 synchronous metastatic colon cancer and 22 rectal cancer lymph nodes were also evaluated. COX-2 expression was assessed by immunohistochemistry. Univariate analysis was used to determine the predictive significance of clinicopathologic variables. Overall survival, disease-specific survival, and disease-free survival were the main outcomes examined. COX-2 was found to be expressed in 93% of colon cancers and 87% of rectal cancers. Decreased COX-2 expression was related to decreased disease-specific survival (P = .016) and decreased disease-free survival (P = .019) in the rectal cancer cohort but not in the colon cancer cohort. COX-2 expression has predictive utility for management of rectal but not colon cancer. Copyright © 2014 Elsevier Inc. All rights reserved.

    The use of hyperthermia to treat cancer is well studied and has utilized numerous delivery techniques, including microwaves, radio frequency, focused ultrasound, induction heating, infrared radiation, warmed perfusion liquids (combined with chemotherapy), and recently, metallic nanoparticles (NP) activated by near infrared radiation (NIR) and alternating magnetic field (AMF) based platforms. It has been demonstrated by many research groups that ablative temperatures and cytotoxicity can be produced with locally NP-based hyperthermia. Such ablative NP techniques have demonstrated the potential for success. Much attention has also been given to the fact that NP may be administered systemically, resulting in a broader cancer therapy approach, a lower level of tumor NP content and a different type of NP cancer therapy (most likely in the adjuvant setting). To use NP based hyperthermia successfully as a cancer treatment, the technique and its goal must be understood and utilized in the appropriate clinical context. The parameters include, but are not limited to, NP access to the tumor (large vs. small quantity), cancer cell-specific targeting, drug carrying capacity, potential as an ionizing radiation sensitizer, and the material properties (magnetic characteristics, size and charge). In addition to their potential for cytotoxicity, the material properties of the NP must also be optimized for imaging, detection and direction. In this paper we will discuss the differences between, and potential applications for, ablative and non-ablative magnetic nanoparticle hyperthermia.

    2014-10-01

    Fatigue is one of the most common adverse effects of cancer that might persist for years after treatment completion in otherwise healthy survivors. Cancer-related fatigue causes disruption in all aspects of quality of life and might be a risk factor of reduced survival. The prevalence and course of fatigue in patients with cancer have been well characterized and there is growing understanding of the underlying biological mechanisms. Inflammation seems to have a key role in fatigue before, during, and after cancer-treatment. However, there is a considerable variability in the presentation of cancer-related fatigue, much of which is not explained by disease-related or treatment-related characteristics, suggesting that host factors might be important in the development and persistence of this symptom. Indeed, longitudinal studies have identified genetic, biological, psychosocial, and behavioural risk factors associated with cancer-related fatigue. Although no current gold-standard treatment for fatigue is available, a variety of intervention approaches have shown beneficial effects in randomized controlled trials, including physical activity, psychosocial, mind-body, and pharmacological treatments. This Review describes the mechanisms, risk factors, and possible interventions for cancer-related fatigue, focusing on recent longitudinal studies and randomized trials that have targeted fatigued patients.

    2004-01-01

    Cervical cancer is one of the most common cancers in women. The purpose of this article is to analyze the main diagnostic and treatment strategies for all stages and recurrences of cervical cancer. The article reviews the epidemiological situation, clinical features, diagnostic procedures for detection of this tumor and for evaluation of the dissemination of the disease, staging criteria, TNM (Tumor, Nodes, Metastases) and FIGO (Federation Internationale de Gynecologie et d'Obstetrique) classification, as well as treatment and prognosis. Surgical treatment (radical type II or III hysterectomy and Iymphadenectomy) for early stage I and IIA cervical cancer is the main treatment method. Delivery of adjuvant postoperative radiation therapy or concomitant chemoradiation depends on the prognostic factors (tumor penetration to cervical tissues, Iymphovascular invasion, tumor invasion to paracervical tissues, and surgical margins). For treatment of more advanced stages of cervical cancer (IIB, IIIA, IIIB, IVA) concomitant chemoradiation: external beam radiotherapy with chemotherapy and brachytherapy is used. Description of the treatment guidelines for each stage of cervical cancer is given in this article. These guidelines are useful for good treatment practice. (author)

    Almost all breast cancer patients receive one or more adjuvant treatments consisting of tamoxifen, aromatase inhibitors, LHRH-antogonists, chemotherapy, trastuzumab, and radiotherapy. These treatments have been shown to considerably improve overall survival. As a result, long term survival for 15 and more years is achieved in more than two thirds of newly diagnosed breast cancer patients. Therefore, more interest in short and long term risks of adjuvant treatments has been arisen. The focus of this article is the long term cardiac risks of adjuvant radiotherapy in breast cancer patients and possible interactions with chemotherapy and trastuzumab. (orig.)

    2013-01-01

    Purpose: Although complementary and alternative medicine (CAM) utilization in breast cancer patients is reported to be high, there are few data on CAM practices in breast patients specifically during radiation. This prospective, multi-institutional study was conducted to define CAM utilization in breast cancer during definitive radiation. Materials/Methods: A validated CAM instrument with a self-skin assessment was administered to 360 Stage 0-III breast cancer patients from 5 centers during the last week of radiation. All data were analyzed to detect significant differences between users/nonusers. Results: CAM usage was reported in 54% of the study cohort (n=194/360). Of CAM users, 71% reported activity-based CAM (eg, Reiki, meditation), 26% topical CAM, and 45% oral CAM. Only 16% received advice/counseling from naturopathic/homeopathic/medical professionals before initiating CAM. CAM use significantly correlated with higher education level (P<.001), inversely correlated with concomitant hormone/radiation therapy use (P=.010), with a trend toward greater use in younger patients (P=.066). On multivariate analysis, level of education (OR: 6.821, 95% CI: 2.307-20.168, P<.001) and hormones/radiation therapy (OR: 0.573, 95% CI: 0.347-0.949, P=.031) independently predicted for CAM use. Significantly lower skin toxicity scores were reported in CAM users vs nonusers, respectively (mild: 34% vs 25%, severe: 17% vs 29%, P=.017). Conclusion: This is the first prospective study to assess CAM practices in breast patients during radiation, with definition of these practices as the first step for future investigation of CAM/radiation interactions. These results should alert radiation oncologists that a large percentage of breast cancer patients use CAM during radiation without disclosure or consideration for potential interactions, and should encourage increased awareness, communication, and documentation of CAM practices in patients undergoing radiation treatment for breast

    2017-06-01

    Full Text Available Thymoquinone (TQ, the main bioactive component of Nigella sativa, has been found to exhibit anticancer effects in numerous preclinical studies. Due to its multitargeting nature, TQ interferes in a wide range of tumorigenic processes and counteracts carcinogenesis, malignant growth, invasion, migration, and angiogenesis. Moreover, TQ can specifically sensitize tumor cells toward conventional cancer treatments (e.g., radiotherapy, chemotherapy, and immunotherapy and simultaneously minimize therapy-associated toxic effects in normal cells. In this review, we summarized the adjuvant potential of TQ as observed in various in vitro and in vivo animal models and discussed the pharmacological properties of TQ to rationalize its supplementary role in potentiating the efficacy of standard therapeutic modalities namely surgery, radiotherapy, chemotherapy, and immunotherapy. Altogether, we suggest further comprehensive evaluation of TQ in preclinical and clinical levels to delineate its implied utility as a novel complementary adjuvant therapy for cancer treatment.

    Treatment planning in gynecologic cancer is a complicated and difficult procedure. It requires an adequate preoperative assessment of the true extent of the patient's disease process and oftentimes this can be achieved not only by conventional studies but must employ surgical exploratory techniques in order to truly define the extent of the disease. However, with contemporary sophisticated treatment planning techniques that are now available in most contemporary departments of radiation oncology, radiation therapy is reemerging as an important and major treatment technique in the management of patients with gynecologic cancer

    Patients with advanced cancer often experience frequent and prolonged hospitalizations; however, the factors associated with greater health care utilization have not been described. We sought to investigate the relation between patients' physical and psychological symptom burden and health care utilization. We enrolled patients with advanced cancer and unplanned hospitalizations from September 2014-May 2016. Upon admission, we assessed physical (Edmonton Symptom Assessment System [ESAS]) and psychological symptoms (Patient Health Questionnaire 4 [PHQ-4]). We examined the relationship between symptom burden and healthcare utilization using linear regression for hospital length of stay (LOS) and Cox regression for time to first unplanned readmission within 90 days. We adjusted all models for age, sex, marital status, comorbidity, education, time since advanced cancer diagnosis, and cancer type. We enrolled 1,036 of 1,152 (89.9%) consecutive patients approached. Over one-half reported moderate/severe fatigue, poor well being, drowsiness, pain, and lack of appetite. PHQ-4 scores indicated that 28.8% and 28.0% of patients had depression and anxiety symptoms, respectively. The mean hospital LOS was 6.3 days, and the 90-day readmission rate was 43.1%. Physical symptoms (ESAS: unstandardized coefficient [B], 0.06; P cancer experience a high symptom burden, which is significantly associated with prolonged hospitalizations and readmissions. Interventions are needed to address the symptom burden of this population to improve health care delivery and utilization.

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

    Fatigue is one of the most common and distressing side effects of cancer and its treatment, and may persist for years after treatment completion in otherwise healthy survivors. Cancer-related fatigue causes disruption in all aspects of quality of life and may be a risk factor for reduced survival. The prevalence and course of fatigue in cancer patients has been well characterized, and there is growing understanding of underlying biological mechanisms. Inflammation has emerged as a key biological pathway for cancer-related fatigue, with studies documenting links between markers of inflammation and fatigue before, during, and particularly after treatment. There is considerable variability in the experience of cancer-related fatigue that is not explained by disease- or treatment-related characteristics, suggesting that host factors may play an important role in the development and persistence of this symptom. Indeed, longitudinal studies have begun to identify genetic, biological, psychosocial, and behavioral risk factors for cancer-related fatigue. Given the multi-factorial nature of cancer-related fatigue, a variety of intervention approaches have been examined in randomized controlled trials, including physical activity, psychosocial, mind-body, and pharmacological treatments. Although there is currently no gold standard for treating fatigue, several of these approaches have shown beneficial effects and can be recommended to patients. This report provides a state of the science review of mechanisms, risk factors, and interventions for cancer-related fatigue, with a focus on recent longitudinal studies and randomized trials that have targeted fatigued patients.

    Cervical disease burden continues to be especially high in HIV-infected women, even in the era of effective antiretroviral medications. This review discusses the multiple issues surrounding HIV-associated cervical cancer. Also, the unique treatment-related issues in HIV-associated cervical cancer are addressed. The incidence of invasive cervical cancer has remained stable in industrialized nations; however, it is only estimated in developing countries secondary to a relative lack of data collection and registries. Trends in HIV-associated cervical cancer have changed in the highly active antiretroviral therapy (HAART) era. Recent molecular pathways suggest that the natural progression of human papillomavirus infection, the causal agent in all cervical cancers, may be related to immune system dysfunction as well as HIV/human papillomavirus synergistic mechanisms. When highly active retroviral therapies are used, invasive cervical cancer treatments are impacted by concomitant drug toxicities that could potentially limit therapeutic benefit of either HAART or the standard of care treatment for locally advanced cervical cancer, concomitant chemoradiotherapy. The significance and care of the patient with invasive cervical cancer is becoming a geographically relevant phenomenon such that it may be time to re-address the global definition. Further studies in treatment issues and drug-drug interactions with cervical cancer treatments in the setting of HIV are paramount.

    Utilization of breast reconstruction services remains low among women who underwent mastectomy despite the improvement in quality of life associated with this treatment. The objective of this study is to identify the effect of the Women's Health and Cancer Rights Act (WHCRA)-an understudied ongoing federal law that mandated insurance coverage of breast reconstruction following mastectomy beginning in 1999-on use of reconstructive surgery after mastectomy. We use a difference-in-differences (DD) approach to identify the change in breast reconstruction utilization induced by WHCRA by comparing the pre- and post-policy changes in utilization between states that did not have existing laws mandating coverage before the WHCRA (treatment group) and those that had such state laws (control group). The data are from the Surveillance, Epidemiology, and End Results program. The main sample includes 15,737 female patients who were under the age of 64 and underwent mastectomy within 4 months of diagnosis of early stage breast cancer during 1998 and 2000. Based on the DD model, the odds of using reconstruction services in the states without preexisting laws increased after the WHCRA by 31% in 1999 and 36% in 2000 (compared with 1998 before the WHCRA). These effects are masked in a simple pre/post model for change in reconstruction across all states. Additional analyses through 2007 indicate that the WHCRA had long-term effects on utilization. Furthermore, analyses by state indicate that most states in the treatment group experienced a significance increase in utilization. The use of breast reconstruction after mastectomy significantly increased after the WHCRA. At a minimum, our estimates may be considered the lower bound of the real policy effect.

    Purpose: To investigate the feasibility of utilizing Dynamic Arc (DA) and IMRT with 5mm MLC leaf of VERO treatment unit for SRS/FSRT brain cancer patients with non-invasive stereotactic treatments. The DA and IMRT plans using the VERO unit (BrainLab Inc, USA) are compared with cone-based planning and proton plans to evaluate their dosimetric advantages. Methods: The Vero treatment has unique features like no rotational or translational movements of the table during treatments, Dynamic Arc/IMRT, tracking of IR markers, limitation of Ring rotation. Accuracies of the image fusions using CBCT, orthogonal x-rays, and CT are evaluated less than ∼ 0.7mm with a custom-made target phantom with 18 hidden targets. 1mm margin is given to GTV to determine PTV for planning constraints considering all the uncertainties of planning computer and mechanical uncertainties of the treatment unit. Also, double-scattering proton plans with 6F to 9F beams and typical clinical parameters, multiple isocenter plans with 6 to 21 isocenters, and DA/IMRT plans are evaluated to investigate the dosimetric advantages of the DA/IMRT for complex shape of targets. Results: 3 Groups of the patients are divided: (1) Group A (complex target shape), CI's are same for IMRT, and DGI of the proton plan are better by 9.5% than that of the IMRT, (2) Group B, CI of the DA plans (1.91+/−0.4) are better than cone-based plan, while DGI of the DA plan is 4.60+/−1.1 is better than cone-based plan (5.32+/−1.4), (3) Group C (small spherical targets), CI of the DA and cone-based plans are almost the same. Conclusion: For small spherical targets, cone-based plans are superior to other 2 plans: DS proton and DA plans. For complex or irregular plans, dynamic and IMRT plans are comparable to cone-based and proton plans for complex targets

    The evolution and development of opinions on the diagnosis and treatment of breast cancer since Galen to present time is presented. The concept of breast cancer as a local disease has been replaced by the understanding of its systemic character. On this background described are the methods of surgical treatment beginning from early - supraradical, to present -conservative approaches. The ''milestones'' in diagnosis and treatment of breast cancer of the last 40 years are presented. Current methods of breast cancer management include correct diagnosis (clinical examination, mammography, ultrasound, fine needle aspiration biopsy), TNM staging, adequate loco-regional therapy, systemic therapy, rehabilitation, reconstruction and careful follow-up.

    Testicular cancer is the most common carcinoma in 20- to 40-year-old men. Eighty percent of patients with metastases achieve disease-free status with chemotherapy with or without surgical resection. Standard first-line chemotherapy is bleomycin, etoposide, and cisplatin (BEP) for three to four courses or etoposide and cisplatin (EP) for four courses. Forty percent of patients receiving chemotherapy will have permanently reduced sperm counts impairing future fertility. Sperm banking is an effective method of maintaining fertility. This retrospective study was performed to assess utilization and results from sperm banking, as well as the barriers to its use. Patients 18 and older who had received chemotherapy were given a five-item questionnaire on follow-up visit. This questionnaire included a mix of quantitative and qualitative questions. Two hundred patients enrolled in the study, and all 200 completed the questionnaire. Of the two hundred, 139 (70 %) patients chose not to bank sperm; 71 (51 %) of those were not interested, 25 (18 %) declined due to desire to start chemotherapy, 24 (17 %) were not offered, 12 (9 %) declined due to cost, and 7 (5 %) answered "other." The average age at cancer diagnosis of patients who banked sperm was 28.4 as opposed to 32.6 for patients who did not (p = 0.003). The percentage of patients that had children before their diagnosis was 21 % in the sperm banking group, and 50 % in the group that did not (p = 0.0002). Sixty-one (30 %) chose to bank sperm; 11 of 61 patients (18 %) utilized the banked sperm; 9 of 11 (82 %) patients that utilized were successful; and 3 of 9 (33 %) successes resulted in multiple gestations. Sperm banking provides the opportunity for paternity in testicular cancer patients with reduced sperm counts following treatment. However, the majority of these patients chose not to bank sperm or were not offered the opportunity. A range of factors such as time, emotional state, patient age, disease stage, prior

    Due to its increasing incidence and its major contribution to healthcare costs, cancer is a major public health problem in the United States. The impact across different services is not well documented and utilization of emergency departments (ED) by cancer patients is not well characterized. The aim of our study was to identify factors that can be addressed to improve the appropriate delivery of quality cancer care thereby reducing ED utilization, decreasing hospitalizations and reducing the related healthcare costs. The New Jersey State Inpatient and Emergency Department Databases were used to identify the primary outcome variables; patient disposition and readmission rates. The independent variables were demographics, payer and clinical characteristics. Multivariable unconditional logistic regression models using clinical and demographic data were used to predict hospital admission or emergency department return. A total of 37,080 emergency department visits were cancer related with the most common diagnosis attributed to lung cancer (30.0%) and the most common presentation was pain. The disposition of patients who visit the ED due to cancer related issues is significantly affected by the factors of race (African American OR=0.6, p value=0.02 and Hispanic OR=0.5, p value=0.02, respectively), age aged 65 to 75years (SNF/ICF OR 2.35, p value=0.00 and Home Healthcare Service OR 5.15, p value=0.01, respectively), number of diagnoses (OR 1.26, p value=0.00), insurance payer (SNF/ICF OR 2.2, p value=0.02 and Home Healthcare Services OR 2.85, p value=0.07, respectively) and type of cancer (breast OR 0.54, p value=0.01, prostate OR 0.56, p value=0.01, uterine OR 0.37, p value=0.02, and other OR 0.62, p value=0.05, respectively). In addition, comorbidities increased the likelihood of death, being transferred to SNF/ICF, or utilization of home healthcare services (OR 1.6, p value=0.00, OR 1.18, p value=0.00, and OR 1.16, p value=0.04, respectively).

    Purpose: This study aimed to quantify the risk of gastrointestinal cancer following Hodgkin's disease treatment according to age at treatment, type of treatment, and anatomic sites. Methods and Materials: Cases were identified from the records of 2,441 patients treated for Hodgkin's disease between 1961 and 1994. Follow-up averaged 10.9 years, representing 26,590 person-years of observation. Relative risks (RR) for gastrointestinal cancer incidence and mortality were computed by comparison with expected annualized rates for a general population matched for age, sex, and race. Results: Gastrointestinal cancers developed in 25 patients. The incidence RR was 2.5 [95% confidence interval (CI), 1.5-3.5] and mortality RR was 3.8 (CI, 2.4-4.7). Sites associated with significantly increased risks included the stomach [RR 7.3 (CI, 3.4-13.8)], small intestine [RR 11.6 (CI, 1.9-38.3)], and pancreas [RR 3.5 (CI, 1.1-8.5)]. Risk was significantly elevated after combined modality therapy, RR 3.9 (CI, 2.2-5.6). The risk after radiotherapy alone was 2.0 (CI, 1.0-3.4), not a statistically significant elevation. The RR for gastrointestinal cancer was greatest after treatment at young age and decreased with advancing age. It was significantly elevated within 10 years after treatment [RR 2.0 (CI, 1.1-3.5)] and increased further after 20 years [RR 6.1 (CI, 2.5-12.7)]. Risk assessed by attained age paralleled risk according to age at treatment. Fifteen cases of gastrointestinal cancers arose within the irradiation fields. Conclusion: Patients treated for Hodgkin's disease are at modestly increased risk for secondary gastrointestinal cancer, especially after combined modality therapy and treatment at a young age. Risk was highest more than 20 years after treatment, but was significantly elevated within 10 years. Gastrointestinal sites with increased risk included the stomach, pancreas, and small intestine

    Low-dose rate brachytherapy (LDR-BT) is a radiation method known for several years in the treatment of localized prostate cancer. The main idea of this method is to implant small radioactive seeds directly into the prostate gland. LDR brachytherapy is applied as a monotherapy and also used along with external beam radiation therapy (EBRT) as a boost. In most cases it is used as a sole radical treatment modality, but not as a palliative treatment. The application of permanent seed implants is a curative treatment alternative in patients with organ- confined cancer, without extracapsular extension of the tumour. This technique is particularly popular in the United States. In Europe, however, high-dose rate brachytherapy (HDR-BT) is more popular in early-stage prostate cancer treatment (as a boost). The aim of this publication is to describe methods, indications, complications and selected results of prostate cancer LDR brachytherapy. (authors)

    Full Text Available ABSTRACTBackground: Prostate cancer is the second most common cancer in American men. The development of alternative preventative and/or treatment options utilizing a combination of phytochemicals and chemotherapeutic drugs could be an attractive alternative compared to conventional carcinoma treatments. Genistein isoflavone is the primary dietary phytochemical found in soy and has demonstrated anti-tumor activities in LNCaP prostate cancer cells. Topotecan Hydrochloride (Hycamtin is an FDA-approved chemotherapy for secondary treatment of lung, ovarian and cervical cancers. The purpose of this study was to detail the potential activation of the intrinsic apoptotic pathway in LNCaP prostate cancer cells through genistein-topotecan combination treatments.Methods: LNCaP cells were cultured in complete RPMI medium in a monolayer (70-80% confluency at 37ºC and 5% CO2. Treatment consisted of single and combination groups of genistein and topotecan for 24 hours. The treated cells were assayed for i growth inhibition through trypan blue exclusion assay and microphotography , ii classification of cellular death through acridine/ ethidium bromide fluorescent staining, and iii activation of the intrinsic apoptotic pathway through Jc-1: mitochondrial membrane potential assay, cytochrome c release and Bcl-2 protein expression.Results: The overall data indicated that genistein-topotecan combination was significantly more efficacious in reducing the prostate carcinoma’s viability compared to the single treatment options. In all treatment groups, cell death occurred primarily through the activation of the intrinsic apoptotic pathway.Conclusion: The combination of topotecan and genistein has the potential to lead to treatment options with equal therapeutic efficiency as traditional chemo- and radiation therapies, but lower cell cytotoxicity and fewer side effects in patients.

    Cancer prehabilitation, a process on the continuum of care that occurs between the time of cancer diagnosis and the beginning of acute treatment, includes physical and psychological assessments that establish a baseline functional level, identifies impairments, and provides targeted interventions that improve a patient's health to reduce the incidence and the severity of current and future impairments. There is a growing body of scientific evidence that supports preparing newly diagnosed cancer patients for and optimizing their health before starting acute treatments. This is the first review of cancer prehabilitation, and the purpose was to describe early studies in the noncancer population and then the historical focus in cancer patients on aerobic conditioning and building strength and stamina through an appropriate exercise regimen. More recent research shows that opportunities exist to use other unimodal or multimodal prehabilitation interventions to decrease morbidity, improve physical and psychological health outcomes, increase the number of potential treatment options, decrease hospital readmissions, and reduce both direct and indirect healthcare costs attributed to cancer. Future research may demonstrate increased compliance with acute cancer treatment protocols and, therefore, improved survival outcomes. New studies suggest that a multimodal approach that incorporates both physical and psychological prehabilitation interventions may be more effective than a unimodal approach that addresses just one or the other. In an impairment-driven cancer rehabilitation model, identifying current and anticipating future impairments are the critical first steps in improving healthcare outcomes and decreasing costs. More research is urgently needed to evaluate the most effective prehabilitation interventions, and combinations thereof, for survivors of all types of cancer.

    Eighty-six children were diagnosed with cancer in infancy, followed for at lest 5 years, and assessed for late effects of disease and therapy. One child subsequently died from respiratory failure and 3 died from second primary cancers. Another patient survived second primary cancers of the skin. The high frequency of new cancers (4 observed, 0.09 expected) was attributable to host susceptibility factors and treatment effects. Kyphoscoliosis was diagnosed in 44 patients, 40 of whom had received radiotherapy to the spine. Other patients had neurologic deficits, pulmonary fibrosis, hypoplastic breasts, bowel adhesions, thyroid nodules, musculoskeletal defects, and liver fibrosis associated with tumor therapy. Sequelae of cancer were more common after treatment in infancy than in later childhood. Improved treatments and knowledge of natural history can reduce adverse effects of therapy

    Purpose: Studies describing the use of the Internet by radiation oncology patients are lacking. This multi-institutional study of cancer patients presenting to academic (AC), community (CO) and veterans (VA) radiation oncology centers was designed to analyze the use of the Internet, predictive factors for utilization, and barriers to access to the Internet. Materials and Methods: A questionnaire evaluating the use of the Internet was administered to 921 consecutive patients presenting to radiation oncology departments at AC, CO and VA Medical Centers. The study included 436 AC patients (47%), 284 CO patients (31%), and 201 VA patients (22%). A computer was available at home to 427 patients (46%) and 337 patients (37%) had Email access. The mean age of the patient population was 64 years (range=14-93). Males represented 70% of the patient population. The most common diagnoses included prostate cancer (33%), breast cancer (13%), and lung cancer (11%). Results: Overall, 265/921 patients (29%) were using the Internet to find cancer related information. The Internet was used by 42% of AC patients, 25% of CO patients and only 5% of VA patients (p<.0001). A computer was available at home in 62% AC vs. 45% CO vs. 12% VA patients (p<.0001). Patients < 60 years were much more likely to use the Internet than older patients (p<.0001). Most of the Internet users considered the information either very reliable (22%) or somewhat reliable (70%). Most patients were looking for information regarding treatment of their cancer (90%), management of side effects of treatment (74%), alternative/complementary treatments (65%) and clinical trials (51%). Unconventional medical therapies were purchased over the Internet by 12% of computer users. Products or services for the treatment or management of cancer were purchased online by 12% of Internet users. Conclusion: A significant number of cancer patients seen in radiation oncology departments at academic and community medical centers

    Relief of pain caused by cancerous invasion is one of the most important role of radiotherapy. Telecobalt has improved the palliative effects for cancer pain, because of its sufficient depth dose. Supervoltage x-ray generated from Linac has expanded indications of treatment for cancer pain by the shortening of treatment time due to high dose rate. Intraoperative electron beam therapy is useful in the case of carcinoma of the pancreas suffering severe pain. Fast neutron therapy is clearly more effective than supervoltage x-ray for pain caused by the invasion of radioresistant cancer. Pelvic angiography is useful for diagnosis of pain focus caused by illiac lymph node metastasis. (author)

    The growing epidemic of human papillomavirus-positive (HPV+) oropharyngeal cancer and the favorable prognosis of this disease etiology have led to a call for deintensified treatment for some patients with HPV+ cancers. One of the proposed methods of treatment deintensification is the avoidance of chemotherapy concurrent with definitive/adjuvant radiotherapy. To the authors' knowledge, the safety of this form of treatment de-escalation is unknown and the current literature in this area is sparse. The authors investigated outcomes after various treatment combinations stratified by American Joint Committee on Cancer (AJCC) eighth edition disease stage using patients from the National Cancer Data Base. A retrospective study of 4443 patients with HPV+ oropharyngeal cancer in the National Cancer Data Base was conducted. Patients were stratified into AJCC eighth edition disease stage groups. Multivariate Cox regressions as well as univariate Kaplan-Meier analyses were conducted. For patients with stage I disease, treatment with definitive radiotherapy was associated with diminished survival compared with chemoradiotherapy (hazard ratio [HR], 1.798; P = .029), surgery with adjuvant radiotherapy (HR, 2.563; P = .002), or surgery with adjuvant chemoradiotherapy (HR, 2.427; P = .001). For patients with stage II disease, compared with treatment with chemoradiotherapy, patients treated with a single-modality (either surgery [HR, 2.539; P = .009] or radiotherapy [HR, 2.200; P = .030]) were found to have poorer survival. Among patients with stage III disease, triple-modality therapy was associated with improved survival (HR, 0.518; P = .024) compared with treatment with chemoradiotherapy. Deintensification of treatment from chemoradiotherapy to radiotherapy or surgery alone in cases of HPV+ AJCC eighth edition stage I or stage II disease may compromise patient safety. Treatment intensification to triple-modality therapy for patients with stage III disease may improve survival in

    Incidence and mortality rates for cancer have increased dramatically in the recent 30 years in Taiwan. However, not all patients receive treatment. Treatment refusal might impair patient survival and life quality. In order to improve this situation, we proposed this study to evaluate factors that are related to refusal of treatment in cancer patients via a cancer case manager system. This study analysed data from a case management system during the period from 2010 to 2012 at a medical center in Northern Taiwan. We enrolled a total of 14,974 patients who were diagnosed with cancer. Using the PRECEDE Model as a framework, we conducted logistic regression analysis to identify independent variables that are significantly associated with refusal of therapy in cancer patients. A multivariate logistic regression model was also applied to estimate adjusted the odds ratios (ORs) with 95% confidence intervals (95%CI). A total of 253 patients (1.69%) refused treatment. The multivariate logistic regression result showed that the high risk factors for refusal of treatment in cancer patient included: concerns about adverse effects (prefuse treatment have poor survival. The present study provides evidence of factors that are related to refusal of therapy and might be helpful for further application and improvement of cancer care.

    Hormone dependence of prostate cancer is well known. In 80% of cases with metastases, hormone suppression leads to the reduction of tumour volume and related disorders. However the treatment is generally palliative because malignant process recurs after about around 16 months. Mean survival is less than 3 years in these forms. Lack of response come always together with a poor prognosis, and there is 90% mortality at 2 years. Advanced prostatic cancer should not be treated with hormones if the patient has few symptoms and his quality of life is satisfactory. Symptomatic forms require hormone manipulation. Orchidectomy or LH-RH are recommended. Total androgen ablation (combined treatment) leads rapidly to more relief of symptoms, but its drawbacks and especially high cost indicate that its use should be weighed individually. Estramustine is not a first-lune treatment. Presently, there is no criteria to predict response to treatment.

    HIV-infected individuals with non-AIDS-defining cancers are less likely to receive cancer treatment compared with uninfected individuals. We sought to identify provider-level factors influencing the delivery of oncology care to HIV-infected patients. A survey was mailed to 500 randomly selected US medical and radiation oncologists. The primary outcome was delivery of standard treatment, assessed by responses to three specialty-specific management questions. We used the χ(2) test to evaluate associations between delivery of standard treatment, provider demographics, and perceptions of HIV-infected individuals. Multivariable logistic regression identified associations using factor analysis to combine several correlated survey questions. Our response rate was 60%; 69% of respondents felt that available cancer management guidelines were insufficient for the care of HIV-infected patients with cancer; 45% never or rarely discussed their cancer management plan with an HIV specialist; 20% and 15% of providers were not comfortable discussing cancer treatment adverse effects and prognosis with their HIV-infected patients with cancer, respectively; 79% indicated that they would provide standard cancer treatment to HIV-infected patients. In multivariable analysis, physicians comfortable discussing adverse effects and prognosis were more likely to provide standard cancer treatment (adjusted odds ratio, 1.52; 95% CI, 1.12 to 2.07). Physicians with concerns about toxicity and efficacy of treatment were significantly less likely to provide standard cancer treatment (adjusted odds ratio, 0.67; 95% CI, 0.53 to 0.85). Provider-level factors are associated with delivery of nonstandard cancer treatment to HIV-infected patients. Policy change, provider education, and multidisciplinary collaboration are needed to improve access to cancer treatment. Copyright © 2015 by American Society of Clinical Oncology.

    Stratification of women with screen-detected ductal carcinoma in situ (DCIS) by risk of subsequent invasive breast cancer (IBC) could assist treatment planning and selection of surveillance protocols that accord with risk. We assessed the utility of routinely collected administrative data for stratifying by IBC risk following DCIS detection in a population-based screening programme to inform ongoing surveillance protocols. A retrospective cohort design was used, employing linked data from the South Australian breast screening programme and cancer registry. Women entered the study at screening commencement and were followed until IBC diagnosis, death or end of the study period (1 December 2010), whichever came first. Routinely collected administrative data were analyzed to identify predictors of invasive breast cancer. Proportional hazards regression confirmed that the DCIS cohort had an elevated risk of IBC after adjustment for relevant confounders (HR = 4.0 (95% CL 3.4, 4.8)), which accorded with previous study results. Within the DCIS cohort, conservative breast surgery and earlier year of screening commencement were both predictive of an elevated invasive breast cancer risk. These linked cancer registry and administrative data gave plausible estimates of IBC risk following DCIS diagnosis, but were limited in coverage of key items for further risk stratification. It is important that the research utility of administrative datasets is maximized in their design phase in collaboration with researchers. © 2016 John Wiley & Sons, Ltd.

    Purpose: We aimed to estimate the optimal proportion of all gynecological cancers that should be treated with brachytherapy (BT)—the optimal brachytherapy utilization rate (BTU)—to compare this with actual gynecological BTU and to assess the effects of nonmedical factors on access to BT. Methods and Materials: The previously constructed inter/multinational guideline-based peer-reviewed models of optimal BTU for cancers of the uterine cervix, uterine corpus, and vagina were combined to estimate optimal BTU for all gynecological cancers. The robustness of the model was tested by univariate and multivariate sensitivity analyses. The resulting model was applied to New South Wales (NSW), the United States, and Western Europe. Actual BTU was determined for NSW by a retrospective patterns-of-care study of BT; for Western Europe from published reports; and for the United States from Surveillance, Epidemiology, and End Results data. Differences between optimal and actual BTU were assessed. The effect of nonmedical factors on access to BT in NSW were analyzed. Results: Gynecological BTU was as follows: NSW 28% optimal (95% confidence interval [CI] 26%-33%) compared with 14% actual; United States 30% optimal (95% CI 26%-34%) and 10% actual; and Western Europe 27% optimal (95% CI 25%-32%) and 16% actual. On multivariate analysis, NSW patients were more likely to undergo gynecological BT if residing in Area Health Service equipped with BT (odds ratio 1.76, P=.008) and if residing in socioeconomically disadvantaged postcodes (odds ratio 1.12, P=.05), but remoteness of residence was not significant. Conclusions: Gynecological BT is underutilized in NSW, Western Europe, and the United States given evidence-based guidelines. Access to BT equipment in NSW was significantly associated with higher utilization rates. Causes of underutilization elsewhere were undetermined. Our model of optimal BTU can be used as a quality assurance tool, providing an evidence-based benchmark against

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

In a placebo-controlled Phase II study of olaparib maintenance therapy (NCT00753545, health-related quality of life was measured using the Functional Assessment of Cancer Therapy – Ovarian (FACT-O questionnaire. Our objective was to generate HSUVs from the FACT-O data using published mapping algorithms. Materials and methods: Algorithms were identified from a review of the literature. Goodness-of-fit and patient characteristics were compared to select the best-performing algorithm, and this was used to generate base-case HSUVs for the intention-to-treat population of the olaparib study and for patients with breast cancer antigen mutations. Results: Four FACT – General (the core component of FACT-O mapping algorithms were identified and compared. Under the preferred algorithm, treatment-related adverse events had no statistically significant effect on HSU (P>0.05. Discontinuation of the study treatment and breast cancer antigen mutation status were both associated with a reduction in HSUVs (–0.06, P=0.0009; and –0.03, P=0.0511, respectively. The mean HSUV recorded at assessment visits was 0.786. Conclusion: FACT – General mapping generated credible HSUVs for an economic evaluation of olaparib. As reported in other studies, different algorithms may produce significantly different estimates of HSUV. For this reason, it is important to test whether the choice of a specific algorithm changes the conclusions of an economic evaluation.

    2007-07-01

    Full Text Available Abstract Background The relationship between radiation exposure for treatment of cancer and occurrence of a second primary cancer at the irradiated site is well known. This phenomenon is however rare in prostate. Case presentation A 75-year-old farmer was treated for rectal cancer with preoperative 45 Gy of radiotherapy and abdominoperineal resection. Four years later he developed symptoms of bladder outlet obstruction and acute urinary retention. He underwent a transurethral resection of the prostate. Histological examination of the removed prostate tissue and immunohistochemistry revealed it to be a poorly differentiated sarcoma. Conclusion We believe this to be the first reported case of radiation-induced sarcoma following radiotherapy treatment for rectal cancer. Since radiotherapy plays a pivotal role in the contemporary treatment of rectal adenocarcinoma, it is relevant to be aware of the potential long-term carcinogenic complications of radiotherapy of the pelvis.

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

    Hypothyroidism following total laryngectomy or radiotherapy treatment for laryngeal cancer is not a rare event, especially in advanced stages. There are no reports on the incidence of hypothyroidism in patients who received chemotherapy and radiotherapy. The objective of this study is to determine the incidence of thyroid dysfunction in a group of patients with laryngeal cancer who underwent surgery as sole treatment, total laryngectomy or radiotherapy alone, and patients with combined treatment: surgery plus radiotherapy, concomitant chemoradiation therapy and chemoradiation therapy plus salvage surgery. A prospective study of patients diagnosed with laryngeal cancer whose serum TSH and T4 levels were evaluated in a serial fashion. 70 patients with laryngeal cancer were studied; the average age at diagnosis was 70.2 years. Male patients were more affected, with a men-women ratio of 3.6:1. Glottic localization was the most frequent (44%). 64% of tumors were locally advanced carcinomas and 51% received multimodal treatment. 45 patients (63%) were diagnosed with hypothyroidism; 49% of the patients with subclinical hypothyroidism, and 51% with clinical hypothyroidism. Hypothyroidism is a complication following treatment for laryngeal cancer. It is recommended to evaluate the thyroid function periodically for timely detection.

    Prostate cancer is one of the most common cancers in men in US and European countries. Despite having a favorable prognosis, the incidence of incurable metastatic disease and mortality in the US is about 28,000 per year. Although hormone-based androgen deprivation therapies typically result in rapid responses, nearly all patients eventually develop progressive castration-resistant disease state. With readily available prostate-specific antigen (PSA) testing, most of these patients are asymptomatic and manifest progression simply as a rising PSA. In patients with castration-resistant prostate cancer (CRPC), the median survival is about 1-2 years, with improvements in survival seen mostly with docetaxel-based regimens. The purpose of this article is to review the recent developments in the treatment of advanced CRPC. Since the two landmark trials (TAX-327 and Southwest Oncology Group 99-16) in CRPC, several newer cytotoxic drugs (epothilones, satraplatin), targeted agents (abiraterone, MDV3100) and vaccines have been tested in phase II and III setting with promising results. The role of newer agents in the treatment of CRPC still needs to be validated by phase III trials, which are currently ongoing. Whilst the novel biomarkers, 'circulating tumor cells', have been shown to provide important prognostic information and are anticipated to be incorporated in future clinical decision-making, their exact utility and relevance calls for a larger prospective validation.

  4. Recent Advances in the Surgical Treatment of Differentiated Thyroid Cancer: A Comprehensive Review

    Directory of Open Access Journals (Sweden)

    2013-01-01

    Full Text Available Differentiated thyroid cancers have become one of the fastest growing malignancies in the world. While surgery has remained the cornerstone of management of these tumors, the surgical approach has seen numerous innovations over the past few decades. The use of video-assistance and robotics has revolutionized thyroid surgery. This paper provides a comprehensive evaluation of the different approaches to thyroid surgery, the utility of prophylactic and therapeutic lymph node dissection, and evidence-based guidelines in the treatment of differentiated thyroid cancers. Minimally invasive video-ssisted thyroidectomy is both safe and effective in the hands of the trained surgeon and, in selected patient populations, has comparative perioperative morbidity and better cosmesis as compared to conventional open thyroidectomy. It is universally accepted that therapeutic central lymph node dissection should be performed when metastatic lymph nodes are identified on physical exam, ultrasound, or intraoperatively. In the absence of overt nodal metastasis, the role of elective prophylactic central lymph node dissection remains a matter of debate and prospective, randomized studies are warranted to evaluate the utility of this procedure.

    Purpose/Objective: To determine if intensity conformal modulated radiotherapy could diminish the radiation dose to the parotid gland in the treatment of primary head and neck cancer. Materials and Methods: The NOMOS Peacock treatment system was utilized in the planning and delivery of conformal radiotherapy for the following diseases: 1) an oropharyngeal cancer that extends from the soft palate to the tonsillar fossa without nodal disease, 2) laryngeal hypopharyngeal cancer without nodal disease, 3) and adenocystic carcinoma, that originated in the hard palate. Patients were treated to areas suspicious for microscopic disease (nodal disease in 1 and 2, perineural spread in 3) at 2 Gy per fraction for a tc of 50 Gy in five weeks. The primary disease was treated at 2.4 Gy per fraction for a total of 60 Gy over five weeks. The percent of the volume of each parotid gland receiving < 20 Gy, <25 Gy and <30 Gy retrospectively was determined for each of the above mentioned optimized plans. The patients were observed for the clinical development of xerostomia. Results: No patient developed clinically apparent xerostomia within one month of completion of radiotherapy. Conclusion: IMBXRT could reduce the volume to parotid glands receiving high radiation doses. Sparing of the parotid glands appear to be most easily accomplished when irradiating head and neck tumors that do not require regional nodal treatment. For head and neck cancer that requires nodal treatment it is possible to spare a significant portion of the parotid glands if the disease originates below the hyoid bone where the primary site is not in close proximity to the parotid glands. Objective salivary flow data are being obtained pre ar post treatment, to confirm the subjective impression of lack of clinical xerostomia. IMBXRT is potentially beneficial in decreasing the morbidity of xerostomia related to head and neck irradiation

  6. A cost-utility analysis of lung cancer screening and the additional benefits of incorporating smoking cessation interventions.

    Directory of Open Access Journals (Sweden)

    Andrea C Villanti

    Full Text Available A 2011 report from the National Lung Screening Trial indicates that three annual low-dose computed tomography (LDCT screenings for lung cancer reduced lung cancer mortality by 20% compared to chest X-ray among older individuals at high risk for lung cancer. Discussion has shifted from clinical proof to financial feasibility. The goal of this study was to determine whether LDCT screening for lung cancer in a commercially-insured population (aged 50-64 at high risk for lung cancer is cost-effective and to quantify the additional benefits of incorporating smoking cessation interventions in a lung cancer screening program.The current study builds upon a previous simulation model to estimate the cost-utility of annual, repeated LDCT screenings over 15 years in a high risk hypothetical cohort of 18 million adults between age 50 and 64 with 30+ pack-years of smoking history. In the base case, the lung cancer screening intervention cost $27.8 billion over 15 years and yielded 985,284 quality-adjusted life years (QALYs gained for a cost-utility ratio of $28,240 per QALY gained. Adding smoking cessation to these annual screenings resulted in increases in both the costs and QALYs saved, reflected in cost-utility ratios ranging from $16,198 per QALY gained to $23,185 per QALY gained. Annual LDCT lung cancer screening in this high risk population remained cost-effective across all sensitivity analyses.The findings of this study indicate that repeat annual lung cancer screening in a high risk cohort of adults aged 50-64 is highly cost-effective. Offering smoking cessation interventions with the annual screening program improved the cost-effectiveness of lung cancer screening between 20% and 45%. The cost-utility ratios estimated in this study were in line with other accepted cancer screening interventions and support inclusion of annual LDCT screening for lung cancer in a high risk population in clinical recommendations.

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

    Full Text Available BACKGROUND: Breast cancer is the most common type of cancer in women in the developed world. As a result of breast cancer treatment, many patients suffer from serious complaints in their arm and shoulder, leading to limitations in activities of daily living and participation. In this systematic literature review we present an overview of the adverse effects of the integrated breast cancer treatment related to impairment in functions and structures in the upper extremity and upper body and limitations in daily activities. Patients at highest risk were defined. METHODS AND FINDINGS: We conducted a systematic literature search using the databases of PubMed, Embase, CINAHL and Cochrane from 2000 to October 2012, according to the PRISMA guidelines. Included were studies with patients with stage I-III breast cancer, treated with surgery and additional treatments (radiotherapy, chemotherapy and hormonal therapy. The following health outcomes were extracted: reduced joint mobility, reduced muscle strength, pain, lymphedema and limitations in daily activities. Outcomes were divided in within the first 12 months and >12 months post-operatively. Patients treated with ALND are at the highest risk of developing impairments of the arm and shoulder. Reduced ROM and muscle strength, pain, lymphedema and decreased degree of activities in daily living were reported most frequently in relation to ALND. Lumpectomy was related to a decline in the level of activities of daily living. Radiotherapy and hormonal therapy were the main risk factors for pain. CONCLUSIONS: Patients treated with ALND require special attention to detect and consequently address impairments in the arm and shoulder. Patients with pain should be monitored carefully, because pain limits the degree of daily activities. Future research has to describe a complete overview of the medical treatment and analyze outcome in relation to the treatment. Utilization of uniform validated measurement

Future research has to describe a complete overview of the medical treatment and analyze outcome in relation to the treatment. Utilization of uniform validated measurement instruments has to be encouraged.

    Cancer patients and survivors are assuming active roles in decision-making and digital patient support tools are widely used to facilitate patient engagement. As part of Cancer Information Service Research Consortium's randomized controlled trials focused on the efficacy of eHealth interventions to promote informed treatment decision-making for newly diagnosed prostate and breast cancer patients, and post-treatment breast cancer, we conducted a rigorous process evaluation to examine the actual use of and perceived benefits of two complementary communication channels -- print and eHealth interventions. The three Virtual Cancer Information Service (V-CIS) interventions were developed through a rigorous developmental process, guided by self-regulatory theory, informed decision-making frameworks, and health communications best practices. Control arm participants received NCI print materials; experimental arm participants received the additional V-CIS patient support tool. Actual usage data from the web-based V-CIS was also obtained and reported. Print materials were highly used by all groups. About 60% of the experimental group reported using the V-CIS. Those who did use the V-CIS rated it highly on improvements in knowledge, patient-provider communication and decision-making. The findings show that how patients actually use eHealth interventions either singularly or within the context of other communication channels is complex. Integrating rigorous best practices and theoretical foundations is essential and multiple communication approaches should be considered to support patient preferences.

    Full Text Available Purpose. To analyze the patterns and associations of adjunctive service visits by head and neck cancer patients receiving primary, concurrent chemoradiation therapy. Methods. Retrospective chart review of patients receiving adjunctive support during a uniform chemoradiation regimen for stages III-IV head and neck squamous cell carcinoma. Univariate and multivariate models for each outcome were obtained from simple and multivariate linear regression analyses. Results. Fifty-two consecutive patients were assessed. Female gender, single marital status, and nonprivate insurance were factors associated with an increased number of social work visits. In a multivariate analysis, female gender and marital status were related to increased social work services. Female gender and stage IV disease were significant for increased nursing visits. In a multivariate analysis for nursing visits, living greater than 20 miles between home and hospital was a negative predictive factor. Conclusion. Treatment of advanced stage head and neck cancer with concurrent chemoradiation warrants a multidisciplinary approach. Female gender, single marital status, and stage IV disease were correlated with increased utilization of social work and nursing services. Distance over 20 miles from the center was a negative factor. This information may help guide the treatment team to allocate resources for the comprehensive care of patients.

  16. Some Aspects Of Adjuvant Treatment Of Colorectal Cancer

    Colorectal cancer is one of the most common cancers in Europe and in North America. Cornerstone of the treatment of localized colorectal cancer is surgical resection followed by chemotherapy or radio-chemotherapy in indicated cases. For patients with Stage III colon cancer recent data have shown efficacy through the combining fluorouracil-based chemotherapy with oxaliplatin into adjuvant treatment program. For patients with Stage II colon cancer, the use of adjuvant chemotherapy remains controversial, but may be appropriate in a subset of individuals at high risk for disease recurrence. Current randomized clinical trials in the adjuvant therapy of colorectal cancer are examining the value of adding agents known to be active in metastatic disease, including those that modify specific molecular targets.

    Full Text Available The purpose of this paper is to present a review of highly developed medicinal usages of plants in the treatment of cancer. In the last decades, the cancer treatment has been included in this range of plant use, due to plant active substances. Active substances or secondary metabolites are generally known for their widespread application. When it comes to the cancer treatment, these substances affect the uncontrolled cell division. Therefore, the plants which are the source of these substances are proved to be irreplaceable in this field of medicine. This paper deals with some of the most significant plants well known for their multiple aspects of beneficial medicinal influence. The group of the plants described is comprised of the following species: Taxus brevifolia (Taxaceae, Catharanthus roseus (Apocynaceae, Podophyllum peltatum (Berberidaceae, Camptotheca accuminata (Cornaceae, and Cephalotaxus harringtonia (Cephalotaxaceae. The comprehensive description of the plants in this paper includes the morphological characteristics, the features and the representation of the molecular structures of active substances, the particular influence that these active substances have and the general importance of the substances as seen from the aspect of cancer treatment mostly with reference to the impacts on cell cycle.

    Healthcare resource utilization in breast cancer varies by disease characteristics and treatment choices. However, lack of clarity in guidelines can result in varied interpretation and heterogeneous treatment management and costs. In Europe, the extent of this variability is unclear. Therefore, evaluation of chemotherapy use and costs versus hormone therapy across Europe is needed. This retrospective chart review (N = 355) examined primarily direct costs for chemotherapy versus hormone therapy in postmenopausal women with hormone-receptor–positive (HR+), human epidermal growth factor receptor-2–negative (HER2–) advanced breast cancer across 5 European countries (France, Germany, The Netherlands, Belgium, and Sweden). Total direct costs across the first 3 treatment lines were approximately €10 000 to €14 000 lower for an additional line of hormone therapy-based treatment versus switching to chemotherapy-based treatment. Direct cost difference between chemotherapy-based and hormone therapy-based regimens was approximately €1900 to €2500 per month. Chemotherapy-based regimens were associated with increased resource utilization (managing side effects; concomitant targeted therapy use; and increased frequencies of hospitalizations, provider visits, and monitoring tests). The proportion of patients taking sick leave doubled after switching from hormone therapy to chemotherapy. These results suggest chemotherapy is associated with increased direct costs and potentially with increased indirect costs (lower productivity of working patients) versus hormone therapy in HR+, HER2– advanced breast cancer.

    2012-04-16

    PURPOSEProlonged and disabling fatigue is prevalent after cancer treatment, but the early natural history of cancer-related fatigue (CRF) has not been systematically examined to document consistent presence of symptoms. Hence, relationships to cancer, surgery, and adjuvant therapy are unclear. PATIENTS AND METHODSA prospective cohort study of women receiving adjuvant treatment for early-stage breast cancer was conducted. Women (n = 218) were enrolled after surgery and observed at end treatment and at 1, 3, 6, 9, and 12 months as well as 5 years. Structured interviews and self-report questionnaires were used to record physical and psychologic health as well as disability and health care utilization. Patients with CRF persisting for 6 months were assessed to exclude alternative medical and psychiatric causes of fatigue. Predictors of persistent fatigue, mood disturbance, and health care utilization were sought by logistic regression.ResultsThe case rate for CRF was 24% (n = 51) postsurgery and 31% (n = 69) at end of treatment; it became persistent in 11% (n = 24) at 6 months and 6% (n = 12) at 12 months. At each time point, approximately one third of the patients had comorbid mood disturbance. Persistent CRF was predicted by tumor size but not demographic, psychologic, surgical, or hematologic parameters. CRF was associated with significant disability and health care utilization. CONCLUSIONCRF is common but generally runs a self-limiting course. Much of the previously reported high rates of persistent CRF may be attributable to factors unrelated to the cancer or its treatment.

    Bone scintigraphy (BS) lacks sensitivity for detecting very early skeletal metastases (SM) in prostate cancer (PC) and is often limited by poor specificity. Also scintigraphic flare of SM can occur following effective treatment and mislead an early response assessment. We hypothesised that a flare reaction might amplify the signal from subclinical SM, increasing the sensitivity of BS and that the phenomenon may be specific for metastases. We conducted a prospective study to determine the frequency of the flare phenomenon in patients with metastatic PC starting hormone therapy and to explore its utility in patients with negative staging scans but considered at high risk of SM and in those with equivocal baseline BS abnormalities. Ninety-nine patients commencing first-line hormone therapy had repeat BS at 6 weeks to score a flare reaction. Of 22 patients with unequivocal SM on the baseline scan, a flare occurred in 9 (41%). Of 36 high-risk localised prostate cancer patients with normal BS pre-treatment, the scan became positive for metastases at 6 weeks in 4 (11%). Of 41 patients with pre-treatment scintigraphic abnormalities of uncertain aetiology, a flare occurred in 8 cases (20%). All eight were confirmed to have SM by follow-up and imaging. Of the 33 remaining patients without a flare, 2 developed SM at 14 months and the remainder did not develop SM in a median follow-up period of 36 months. The flare phenomenon following initial hormone therapy can be used to improve both sensitivity and specificity of BS in PC. (orig.)

    The benefits of exercise training for cancer patients are becoming increasingly evident. Physical exercise has been shown to reduce cancer incidence and inhibit tumor growth. Here we provide the status of the current molecular understanding of the effect of exercise on cancer. We propose...... that exercise has a role in controlling cancer progression through a direct effect on tumor-intrinsic factors, interplay with whole-body exercise effects, alleviation of cancer-related adverse events, and improvement of anti-cancer treatment efficacy. These findings have wide-ranging societal implications......, as this understanding may lead to changes in cancer treatment strategies.

    Full text: The aim of this study was to evaluate the impact of positron emission tomography/computerised tomography (PET/CT) as an adjunct to conventional imaging (CI) in the management of nasopharyngeal cancer (NPC) both for initial staging and assessment of post-treatment response. Methods: All NPC cases referred to the Peter MacCallum Centre for Metabolic Imaging between January 2002 and December 2007 were identified, In patients undergoing initial staging, any differences between the pre PET/CT management plan based on CI and that following performance of the PET/CT scan were noted. Clinical impact was scored using the Centre's published criteria: 'high' if PET /CT changed the primary treatment modality or intent, 'medium' if treatment modality was unchanged but the radiotherapy technique or dose was altered, and 'low' if there was no change in treatment modality or intent. Patients undergoing PET/CT following definitive treatment were scored according to whether or not they achieved a complete metabolic response. Results: Forty-eight patients underwent a staging PET/CT. The clinical impact was high in 8%, medium in 25% and low in 66% of patients. Twenty-one patients were scanned for post-treatment response. PET/CT was less frequently equivocal than MRI (3 vs 8/21). A complete metabolic response on PET /CT was associated with a 93% negative predictive value for subsequent recurrence. Conclusion: PET /CT is a valuable staging tool for the detection of occult metastatic disease and defining the extent of neck nodal disease, Pos treatment, a complete metabolic response on PET /CT has a very high negative predictive value with fewer equivocal results than MRI.

    Endoscopic resection is established in the treatment of early gastric cancer. More advanced gastric cancer requires gastrectomy and D2 lymphadenectomy. Perioperative chemotherapy improves overall survival in locally advanced gastric cancer representing a standard of care. Locally advanced adenocarcinomas of the esophago-gastric junction can alternatively be treated with concurrent radiochemotherapy. In metastatic disease, systemic chemotherapy improves survival, quality of life and symptom control. Trastuzumab plus chemotherapy should be used together with first-line chemotherapy in HER2 positive gastric cancer patients. Second- and third-line therapy is now well established. The anti-VEGFR2 antibody Ramucirumab improves survival in second line treatment both as a monotherapy and in combination with paclitaxel and represents a novel treatment option. © Georg Thieme Verlag KG Stuttgart · New York.

    HIV-infected individuals with cancer have worse survival rates compared with their HIV-uninfected counterparts. One explanation may be differing cancer treatment; however, few studies have examined this. We used HIV and cancer registry data from Connecticut, Michigan, and Texas to study adults diagnosed with non-Hodgkin's lymphoma, Hodgkin's lymphoma, or cervical, lung, anal, prostate, colorectal, or breast cancers from 1996 to 2010. We used logistic regression to examine associations between HIV status and cancer treatment, adjusted for cancer stage and demographic covariates. For a subset of local-stage cancers, we used logistic regression to assess the relationship between HIV status and standard treatment modality. We identified predictors of cancer treatment among individuals with both HIV and cancer. We evaluated 3,045 HIV-infected patients with cancer and 1,087,648 patients with cancer without HIV infection. A significantly higher proportion of HIV-infected individuals did not receive cancer treatment for diffuse large B-cell lymphoma (DLBCL; adjusted odds ratio [aOR], 1.67; 95% CI, 1.41 to 1.99), lung cancer (aOR, 2.18; 95% CI, 1.80 to 2.64), Hodgkin's lymphoma (aOR, 1.77; 95% CI, 1.33 to 2.37), prostate cancer (aOR, 1.79; 95% CI, 1.31 to 2.46), and colorectal cancer (aOR, 2.27; 95% CI, 1.38 to 3.72). HIV infection was associated with a lack of standard treatment modality for local-stage DLBCL (aOR, 2.02; 95% CI, 1.50 to 2.72), non-small-cell lung cancer (aOR, 2.43; 95% CI, 1.46 to 4.03), and colon cancer (aOR, 4.77; 95% CI, 1.76 to 12.96). Among HIV-infected individuals, factors independently associated with lack of cancer treatment included low CD4 count, male sex with injection drug use as mode of HIV exposure, age 45 to 64 years, black race, and distant or unknown cancer stage. HIV-infected individuals are less likely to receive treatment for some cancers than uninfected people, which may affect survival rates. © 2014 by American Society of Clinical

    Geographic barriers and limited availability of cancer specialists may influence early prostate cancer treatment options for rural men. This study compares receipt of different early prostate cancer treatments between rural and urban patients. Using 2004-2006 SEER Limited-Use Data, 51,982 early prostate cancer patients were identified (T1c, T2a, T2b, T2c, T2NOS; no metastases) who were most likely to benefit from definitive treatment (rural-urban residence overall, and for different sociodemographic and cancer characteristics, and different states based on logistic regression analyses, using general estimating equation methods to account for clustering by county. Adjusted definitive treatment rates were lower for rural (83.7%) than urban (87.1%) patients with early-stage prostate cancer (P ≤ .01). Rural men were more likely than urban men to receive non-definitive surgical treatment and no initial treatment. The lowest definitive treatment rates were among rural subgroups: 70 to 74 years (73.9%), African Americans (75.6%), American Indians/Alaska Natives (77.8%), single/separated/divorced (76.8%), living in New Mexico (69.3%), and living in counties with persistent poverty (79.6%). Between 2004 and 2006, this adjusted analysis found that men who were living in rural areas were less likely to receive definitive treatment for their early-stage prostate cancer than those living in urban areas. Certain rural patient groups with prostate cancer need particular attention to ensure their access to appropriate treatment. Rural providers, rural health care systems, and cancer advocacy and support organizations should ensure resources are in place so that the most vulnerable rural groups (men between 60 and 74 years of age; African American men; men who are single, separated, or divorced; and men living in rural New Mexico) can make informed prostate cancer treatment choices based on their preferences.

    The purpose of this study was to describe the process of coping with the experience of receiving intracavity radiation treatment (ICR) for gynecologic cancer. Data were collected on the outcomes of coping, emotion (Profile of Mood States) and level of function (Sickness Impact Profile), and symptom severity and upset the evening before, during, the day after, and 1 to 2 weeks after treatment. The subjects (N = 28) had a mean age of 52 years, 39% were employed full-time, 56% had occupations as manual workers, 57% had completed 12 or more years of education, and 68% were married or widowed. The treatment required the subjects to be hospitalized on complete bedrest with radiation precautions for an average of 48 hours. Intrauterine devices were used to treat 18 subjects and vaginal applications were used to treat 10 subjects. Negative mood and level of disruption in function were generally low. Repeated measures ANOVA showed no change in negative mood over time while the change in function was attributable to the increase in disruption during treatment. Utilization of affective coping strategies and problem-oriented coping strategies was positively correlated with negative mood and disruption in function over the points of measurement. The results indicate that subjects tolerated ICR well and rapidly resumed usual function following discharge from the hospital, despite the persistence of some symptoms 1 to 2 weeks after treatment. The positive association between the utilization of coping strategies and negative outcomes of coping suggests a need to examine the measurement of coping strategies and consider the possibility that these actions represent a response to a stressful situation rather than a method of dealing with the situation

    As soon as 1936 an American physicist proposed to treat certain forms of cancer by using the nuclear reaction: n + 10 B → 7 Li + 4 He where the alpha particles produced could destroy the DNA of surrounding cells. From 1951 to 1961 62 patients underwent this treatment for brain cancer. The results were unsatisfactory: the neutrons were not energetic enough to enter brain tissues deeply and were accompanied by strongly damaging gamma radiation. In Netherlands an installation using the high flux reactor of Petten has been set up. A highly focused neutron beam of about 10 keV with reduced gamma radiation is produced. The first step is to determine the limit exposure and the maximal permissible concentration of boron. (A.C.)

    2017-03-01

    Many patients with life-limiting illnesses continue to work because of financial reasons and because work provides good psychosocial support. A lack of appropriate advice/support through patient education could, however, make having a job detrimental to well-being (eg, symptom worsening). This study investigated the frequency with which patients received information that empowers their understanding of their condition, treatment, side effects of treatment and the likely impact on occupational functioning. A cross-sectional study. An analysis of survey data from 3457 patients with cancer in employment. Logistic regression showed that patients who received information about the impact of cancer on work life or education are 1.72 times more likely to have a positive treatment outcome. Patients who receive written information about the type of cancer are 1.99 times more likely to have a positive treatment outcome. Also, patients who receive written information before a cancer-related operation are 1.90 times more likely to have a positive treatment outcome. Information about the side effects of cancer treatment produces worse odds of a positive treatment outcome (0.65-1). A stepwise logistic regression analysing the effects irrespective of current employment status in 6710 patients showed that preparing them produces nearly twice better odds of cancer treatment responsiveness. Palliative care teams should consider ways of actively advising patients who work. Whereas the results showed evidence of good practice in cancer care, there is a need to ensure that all working patients with potentially life-limiting illnesses receive similar support.

    2014-03-15

    This article defines and describes best practices for the academic and business community to generate evidence of clinical utility for cancer molecular diagnostic assays. Beyond analytical and clinical validation, successful demonstration of clinical utility involves developing sufficient evidence to demonstrate that a diagnostic test results in an improvement in patient outcomes. This discussion is complementary to theoretical frameworks described in previously published guidance and literature reports by the U.S. Food and Drug Administration, Centers for Disease Control and Prevention, Institute of Medicine, and Center for Medical Technology Policy, among others. These reports are comprehensive and specifically clarify appropriate clinical use, adoption, and payer reimbursement for assay manufacturers, as well as Clinical Laboratory Improvement Amendments-certified laboratories, including those that develop assays (laboratory developed tests). Practical criteria and steps for establishing clinical utility are crucial to subsequent decisions for reimbursement without which high-performing molecular diagnostics will have limited availability to patients with cancer and fail to translate scientific advances into high-quality and cost-effective cancer care.

    Purpose Individuals diagnosed with cancer close to death have low access to enrollment in palliative care programs. The purpose of this literature review was to assess the usefulness of pre-diagnostic comorbidity and healthcare utilization as indicators of late-stage colorectal cancer (CRC) diagnosis, to help with early identification of individuals who may benefit from palliative care. Methods A literature search was conducted in relevant databases using title/abstract terms which included “cancer,” “stage,” “diagnosis,” “determinants,” “predictors,” and “associated.” Included studies examined whether comorbidity and/or healthcare utilization had an impact on the stage at which CRC was diagnosed. A standardized data abstraction form was used to assess the eligibility of each study. Thirteen articles were included in the literature review. These studies were assessed and synthesized using qualitative methodology. Results We found much heterogeneity among study variables. The findings of this literature review point to the presence of comorbidity and non-emergent healthcare utilization as having no association with late-stage diagnosis. Conversely, emergency room presentation (ERP) was associated with late-stage diagnosis. Conclusions The results of this literature review did not find strong evidence to suggest that comorbidity and healthcare utilization are potential indicators of late-stage diagnosis. However, ERP may be useful as a flag for consideration of prompt referral to palliative care. Additional research is required to identify potential indicators of late-stage diagnosis that may be available in administrative databases, particularly in the area of healthcare utilization.

    Worldwide cervical cancer is one of the more common forms of carcinoma among women, causing high morbidity and high mortality. Despite being a major health problem in Tanzania, screening services for cervical cancer are very limited, and uptake of those services is low. We therefore conducted a study to investigate utilization of cancer screening services, and its associated factors among female primary school teachers in Ilala Municipality, Dar es Salaam. We conducted a cross-sectional study between May - August 2011 which involved 110 primary schools in Ilala Municipality in Dar es Salaam. Five hundred and twelve female primary school teachers were sampled using a two-stage cluster sampling procedure. Data on utilization of cervical cancer and risk factors were collected using a self-administered questionnaire. Proportional utilization of cervical cancer screening services was identified through a self report. Risk factors for services utilization were assessed using logistic regression analyses. Out of 512 female primary school teachers, only 108 (21 %) reported to ever been screened for cervical cancer. Utilization of cervical cancer screening services was 28 % among those aged 20-29, 22 % among married and 24 % among those with higher level of education. Women were more likely to utilize the cancer-screening service if they were multiparous (age-adjusted OR = 3.05, 95 % CI 1.15-8.06, P value 0.025), or reported more than one lifetime sexual partner (age-adjusted OR 2.17, 95 % CI 1.04-4.54, P value 0.038), or did not involve their spouse in making health decisions (adjusted OR 3.56, 95 % CI 2.05-6.18, P value service among female primary school teachers in Ilala munipality. Female primary school teachers with more than one previous pregnancy and those with more than one life-time sex partners were more likely to report utilization of the service. Spouse or partners support was an important factor in the utilization of cervical cancer screening

    The number of people who are dying from cancer has been increasing in association with population aging. Radiation therapy is now one of the three major cancer treatment methods, along with surgery and chemotherapy. People used to consider radiation therapy only as a ''noninvasive cancer treatment''; however, with the ceaseless effort by medical experts and corporations, different radiation therapy types and techniques including the latest technical advances have come out one after another, and the improvements in radiation therapies have provided treatments that are not only less traumatizing to patients but also as effective and therapeutic as surgery in certain body regions. The importance of radiation therapy has become and will become even greater in the society with more elderly cancer patients who do not have the physical strength to undergo surgery. In this article, the history of radiation therapy, rapidly developed high-precision radiation therapy techniques, and unsolved issues are discussed, and then, ''MHI vero4DRT'', which is the high-precision image-guided radiation therapy equipment developed for solving such issues, is introduced.

    The emerging field of nanotechnology meets the demands for innovative approaches in the diagnosis and treatment of cancer. The nanoparticles are biocompatible and biodegradable and are made of a core, a particle that acts as a carrier, and one or more functional groups on the core which target specific sites. Nanotech in drug delivery includes nanodisks, High Density Lipoprotein nanostructures, liposomes, and gold nanoparticles. The fundamental advantages of nanoparticles are: improved delivery of water-insoluble drugs, targeted delivery, co-delivery of two or more drugs for combination therapy, and visualization of the drug delivery site by combining imaging system and a therapeutic drug. One of the potential applications of nanotechnology is in the treatment of cancer. Conventional methods for cancer treatments have included chemotherapy, surgery, or radiation. Early recognition and treatment of cancer with these approaches is still challenging. Innovative technologies are needed to overcome multidrug resistance, and increase drug localization and efficacy. Application of nanotechnology to cancer biology has brought in a new hope for developing treatment strategies on cancer. In this study, we present a review on the recent advances in nanotechnology-based approaches in cancer treatment. Copyright© 2017, International Institute of Anticancer Research (Dr. George J.

    2016-02-15

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

    Fatigue is a common symptom in cancer patients that can persist beyond the curative treatment phase. Some evidence has been reported for interventions for fatigue during active treatment. However, to date, there is no systematic review on psychological interventions for fatigue after the completion of curative treatment for cancer. This is a protocol for a systematic review that aims to evaluate the effectiveness of psychological interventions for cancer-related fatigue in post-treatment cancer survivors. This systematic review protocol was registered with the International Prospective Register of Systematic Reviews (PROSPERO) database. We will search the Cochrane Central Register of Controlled Trials (CENTRAL; The Cochrane Library), PubMed, MEDLINE, EMBASE, CINAHL, PsycINFO, and relevant sources of grey literature. Randomised controlled trials (RCTs) which have evaluated psychological interventions in adult cancer patients after the completion of treatment, with fatigue as an outcome measure, will be included. Two review authors will independently extract data from the selected studies and assess the methodological quality using the Cochrane Collaboration Risk of Bias Tool. Most existing evidence on cancer-related fatigue is from those in active cancer treatment. This systematic review and meta-analysis will build upon previous evaluations of psychological interventions in people during and after cancer treatment. With the growing need for stage-specific research in cancer, this review seeks to highlight a gap in current practice and to strengthen the evidence base of randomised controlled trials in the area.

    Cancer is a generic term for a large group of diseases characterized by rapid creation of abnormal cells that grow beyond their usual boundaries, and which can then invade adjoining parts of the body and spread to other organs. Cancer mortality is the second and most common cause of death in the USA and in most European countries. In India, it is the fourth leading disease and the major cause of death. Cancer remains one of the most dreadful disease and approximately ten million cases of cancer occur in the world every year. The course of cancer treatment depends on the type of cancer, its location, and its state of advancement. Cancer is treated with surgery, chemotherapy, radiation therapy, hormone therapy, biological therapy and targeted therapy. Radiation therapy is an important an affordable modality for cancer treatment with minimal side effects. Radiation kills cancer cells with high-energy rays targeted directly to the tumor. Radiation therapy works by damaging the DNA and preventing its replication: therefore, it preferentially kills cancer cells, which rapidly divides. Radiation therapy is used for cure, control, and palliation of cancers in more than 60% of cancer patients. The goal of radiotherapy is to treat the cancer and spare the normal tissue as much as possible. Advances have been made in radiotherapy that allow delivery of higher doses of radiation to the tumor while sparing a greater amount of surrounding tissue, thus achieving more cures and fewer acute and long-term side effects. Technological advances and research are being continued to result in improvements in the field. Several new devices and techniques are used these days in radiotherapy for accurate treatment of cancer. Teletherapy (external radiation therapy) used focused radiation beams targeting well defined tumor through extremely detailed imaging scans. Conventional external beam radiation therapy (2DXRT) is delivered via two-dimensional beams using linear accelerator machines (X

    Estimates of second primary cancers risk after radiotherapy has become increasingly important for comparative treatment planning. A new method based on the treatment planning system to estimate the risk of second primary cancers was introduced in this paper. Using the Advanced/Accurate Radiotherapy Treatment System(ARTS), a treatment planning system developed by the FDS team,the risk of second primary cancer was estimated over two treatment plans for a patient with pancreatic cancer. Based on the second primary cancer risk, the two plans were compared. It was found that,kidney and gall-bladder had higher risk to develop second primary cancer. A better plan was chosen by the analysis of second primary cancer risk. The results showed that this risk estimation method we developed could be used to evaluate treatment plans. (authors)

    Over 7 years, 57 women with breast cancer underwent lumpectomy and bilateral mammoreduction. Physical complaints about large or lax breast shape were the predominate rationale. Two patients were immediately lost to follow-up, 55 patients remained and were followed every 3 months for an average of 1.6 years. This is the largest series traceable by computer and literature search. Chart review and patient examination in this retrospective review were utilized as the basis for data within the article. Collated notes from patients' doctors were assessed, as well as documented patient responses to the procedure. Pictures without head/face for identifiers were taken of the patients. Chart data were collected by clinicians, but were reviewed blindly by a statistician. The overall control and cosmesis rates as well as alleviation of heavy breast problems were noted. Only 6% of women had fair to poor cosmetic results; the majority (82%) had excellent to good results. Women with very large breasts or markedly relaxed breast tissue of concern to the patients proved optimal candidates for lumpectomy of cancer and bilateral mammoreduction in the conservative treatment of these cancers. There was a significant reduction in the physical complaints of the patients as well. For women with very pendulous or extremely large breasts, lumpectomy and bilateral mammoreduction may prove to be the optimal course of action.

    Full Text Available IntroductionUtilization of patient-reported outcomes (PROs to guide symptom management during radiation therapy is increasing. This study focuses on the use of the Expanded Prostate Cancer Index Composite for Clinical Practice (EPIC-CP as a tool to assess urinary and bowel bother during stereotactic body radiation therapy (SBRT and its utility in guiding medical management.MethodsBetween September 2015 and January 2017, 107 patients with clinically localized prostate cancer were treated with 35–36.25 Gy via SBRT in five fractions. PROs were assessed using EPIC-CP 1 h prior to the first fraction and after each subsequent fraction. Symptom management medications were prescribed based on the physician clinical judgment or if patients reported a moderate to big problem. Clinical significance was assessed using a minimally important difference of 1/2 SD from baseline score.ResultsA median baseline EPIC-CP urinary symptom score of 1.5 significantly increased to 3.7 on the day of the final treatment (p < 0.0001. Prior to treatment, 9.3% of men felt that their overall urinary function was a moderate to big problem that increased to 28% by the end of the fifth treatment. A median baseline EPIC-CP bowel symptom score of 0.3 significantly increased to 1.4 on the day of the final treatment (p < 0.0001. Prior to treatment, 1.9% of men felt that their overall bowel function was a moderate to big problem that increased to 3.7% by the end of the fifth treatment. The percentage of patients requiring an increased dose of alpha-antagonist increased to 47% by the end of treatment, and an additional 28% of patients required a short steroid taper to manage moderate to big urinary problems. Similarly, the percentage of patients requiring antidiarrheals reached 12% by the fifth treatment.ConclusionDuring the course of SBRT, an increasing percentage of patients experienced clinically significant symptoms many of which required medical management

    Effectiveness and low-toxicity to normal tissues are ideal properties for a cancer treatment, and one that numerous research programs are aiming for. Vitamin C has long been used in the field of Complementary and Alternative Medicine as a cancer treatment, with profound safety and anecdotal efficacy. Recent studies revealed the scientific basis for this use, and indicated that vitamin C, at supra-nutritional doses, holds considerable promise as an effective and low-toxic therapeutic strategy to treat cancer. Reviewed here are the early controversies surrounding vitamin C and cancer treatment, the breakthrough discoveries that led to the current advancement, and recent clinical studies, as well as research into its mechanisms of action.

    Surgical resection has been traditionally the mainstay of treatment for localized esophageal cancers. However, survival after surgery alone for advanced esophageal cancer is not satisfactory. In Japan, the development of multimodal therapy for esophageal cancers has centered mainly on systemic chemotherapy plus surgery to control distant metastasis. Based on the results of the recent Japan Clinical Oncology Group (JCOG) 9907 study, preoperative chemotherapy (consisting of 5-fluorouracil (FU) and cisplatin) followed by surgery has emerged as the standard treatment. In Western countries, where chemoradiotherapy followed by surgery has been mainly explored for patients with resectable esophageal cancers, two large controlled trials that evaluated the effectiveness of preoperative chemotherapy reported conflicting results. However, a recent meta-analysis reported significant survival benefits for preoperative chemotherapy in patients with adenocarcinoma of the esophagus. We need to find new effective preoperative chemotherapeutic regimens, including molecular target agents, with response rates higher than that of the conventional chemotherapy of 5-FU and cisplatin. However, we also must compare the survival benefits of preoperative chemotherapy with preoperative chemoradiotherapy. (author)

    Full Text Available Abstract Background Progress in lung cancer is hampered by the lack of clinically useful diagnostic markers. The goal of this study was to provide a detailed evaluation of lung cancer tumor markers indicative of molecular abnormalities and to assess their diagnostic utility in non-small cell lung cancer (NSCLC patients. Methods Quantitative real-time RT-PCR was used to determine LunX, CK19, CEA, VEGF-C and hnRNP A2/B1 mRNA levels in peripheral blood and pleural fluid from NSCLC patients, compared with those from patients with other epithelial cancer (esophagus cancer and breast cancer, benign lung disease (pneumonia and tuberculo pleurisy and from healthy volunteers. Results In peripheral blood LunX mRNA was detectable in 75.0% (33/44 of patients with NSCLC, but not in patients with other epithelial cancer (0/28, benign lung disease (0/10 or in healthy volunteers (0/15. In contrast, all other genetic markers were detected in patients with either NSCLC, other epithelia cancer or benign lung disease, and in healthy volunteers. The expression level and positive rate of LunX mRNA in peripheral blood correlated with the pathologic stage of NSCLC (P LunX mRNA was detected in 92.9% (13/14 of malignant pleural fluid samples and was the only marker whose expression level was significantly different between malignant and benign pleural fluid (P LunX mRNA in the peripheral blood of NSCLC patients decreased shortly after clinical treatment (P = 0.005. Conclusion Of several commonly used genetic markers, LunX mRNA is the most specific gene marker for lung cancer and has potential diagnostic utility when measured in the peripheral blood and pleural fluid of NSCLC patients.

    Approximately 170,000 people are diagnosed with lung cancer in the United States each year. Many of these patients receive external beam radiation for treatment. Fluorine-18 2-fluoro-2-deoxy-d-glucose positron emission tomography (FDG PET) is increasingly being used in evaluating non-small cell lung cancer and may be of clinical utility in assessing response to treatment. In this report, we present FDG PET images and data from two patients who were followed with a total of eight and seven serial FDG PET scans, respectively, through the entire course of their radiation therapy. Changes in several potential response parameters are shown versus time, including lesion volume (V FDG ) by PET, SUV av , SUV max , and total lesion glycolysis (TLG) during the course of radiotherapy. The response parameters for patient 1 demonstrated a progressive decrease; however, the response parameters for patient 2 showed an initial decrease followed by an increase. The data presented here may suggest that the outcome of radiation therapy can be predicted by PET imaging, but this observation requires a study of additional patients. (orig.)

    2017-12-01

    Prostate cancer (PC) is the most common cancer in Western countries. More than one third of PC patients develop metastatic disease, and the 5-year expected survival in distant disease is about 35%. During the last few years, new treatments have been launched for metastatic castrate-resistant prostate cancer (mCRPC). We aimed to review the current literature on health economic analysis on the treatment of metastatic prostate cancer (mPC), compare the studies, summarize the findings and make the results available to administrators and decision makers. A systematic literature search was done for economic evaluations (cost-minimization, cost-effectiveness, cost-utility, cost-of-illness, cost-of-drug, and cost-benefit analyses). We employed the PubMed ® search engine and searched for publications published between 2012 and 2016. The terms used were "prostate cancer", "metastatic" and "cost". An initial screening of all headlines was performed, selected abstracts were analysed, and finally the full papers investigated. Study characteristics, treatment and comparator, country, type of evaluation, perspective, year of value, time horizon, efficacy data, discount rate, total costs and sensitivity analysis were analysed. The quality was assessed using the Quality of Health Economic Studies (QHES) instrument. A total of 227 publications were detected and screened, 58 selected for full-text assessment and 31 included in the final analyses. Despite the significant international literature on the treatment of mCRPC, there were only 15 studies focusing on cost-effectiveness analysis (CEA). Medical treatment constituted two thirds of the selected studies. Significant costs in the treatment of mCRPC were disclosed. In the pre-docetaxel setting, both abiraterone acetate (AA) and enzalutamide were concluded beyond accepted cost/quality-adjusted life year limits. In the docetaxel refractory setting, most studies concluded that enzalutamide was cost-effective and superior to AA. In

  18. Current status of brachytherapy in cancer treatment – short overview

    Full Text Available Cancer incidence and mortality depend on a number of factors, including age, socio-economic status and geographical location, and its prevalence is growing around the world. Most of cancer treatments include external beam radiotherapy or brachytherapy. Brachytherapy, a type of radiotherapy with energy from radionuclides inserted directly into the tumor, is increasingly used in cancer treatment. For cervical and skin cancers, it has become a standard therapy for more than 100 years as well as an important part of the treatment guidelines for other malignancies, including head and neck, skin, breast, and prostate cancers. Compared to external beam radiotherapy, brachytherapy has the potential to deliver an ablative radiation dose over a short period of time directly to the altered tissue area with the advantage of a rapid fall-off in dose, and consequently, sparing of adjacent organs. As a result, the patient is able to complete the treatment earlier, and the risks of occurrence of another cancer are lower than in conventional radiotherapy treatment. Brachytherapy has increased its use as a radical or palliative treatment, and become more advanced with the spread of pulsed-dose-rate and high-dose-rate afterloading machines; the use of new 3D/4D planning systems has additionally improved the quality of the treatment. The aim of the present study was to present short summaries of current studies on brachytherapy for the most frequently diagnosed tumors. Data presented in this manuscript should help especially young physicians or physicists to explore and introduce brachytherapy in cancer treatments.

    To establish the need for a sequential radiological study to contribute, together with other specialists in the management of these patients, to achieve the best possible results with this type of treatment: rates of survival comparable to those obtained with mastectomy and the highest possible percentages of breast preservation with satisfactory cosmetic results. Studies of 200 patients who underwent conservative treatment for breast cancer at Clinica Puerta de Hierro in Madrid over the past five years.We assess the utility of the different imaging methods and their application in each specific case. An update of the literature is also carried out. Radiology plays a major role in the management of patients who undergo conservative treatment for breast cancer. We demonstrate the need to carry out, in the first place, preoperative radiological studies to aid in the proper selection of patients and, secondly, examination of the resected tissue and postoperative mammography to ensure that the surgical resection was performed correctly. Finally, follow-up studies be carried out to detect tumor recurrence as early as possible. (Author) 82 refs

    Previous studies indicated that breast cancer is wildly spread especially in women as compared to men. It is increased after an age of thirty five years in women so it is important to study the effect of exposure to the radiation on the intact breast during the treatment of the breast suffering from cancer. In this work the scattered doses for the intact breast during the treatment of the breast suffering from cancer were measured and also the probability of inducing cancer in it is also discussed. The study was performed for a group of patients composed of twenty five females. Also the backscattered doses to the intact breast were measured for thirteen female patients. During the treatment using gamma rays from Co-60 source the two tangential fields (lateral and medial) were selected for the measurements. The results of exposure to gamma radiation for the lateral and medial fields showed that the mean scattered and backscattered doses to the intact breast were (241.26 cGY,47.49 cGY) and (371.6 cGY,385.4 cGY), respectively. Beside that the somatic risk of induced cancer to the intact breast was found to be (6 .1X10 -3 ,1.2X10 -3 ) and (9.29X10 -3 , 9.63X10 -3 ), respectively. From the results obtained it was concluded that the intact breast received small amounts of radiation doses which may lead to breast cancer for the healthy breast. The recommendations from the present study are to take care of radiation protection to the patient, and also to take care of the patient treatment conditions like temperature, pressure and humidity during the radiation exposure.(Author)

    Full Text Available Abstract Background Colorectal cancer screening is widely recommended, but often under-utilized. In addition, significant demographic differences in screening utilization exist. Insurance coverage may be one factor influencing utilization of colorectal cancer screening tests. Methods We conducted a retrospective analysis of claims for outpatient services for Washington state Medicare beneficiaries in calendar year 2000. We determined the proportion of beneficiaries utilizing screening fecal occult blood tests, flexible sigmoidoscopy, colonoscopy, or double contrast barium enema in the overall population and various demographic subgroups. Multiple logistic regression analysis was used to determine the relative odds of screening in different demographic groups. Results Approximately 9.2% of beneficiaries had fecal occult blood tests, 7.2% had any colonoscopy, flexible sigmoidoscopy, or barium enema (invasive colon tests, and 3.5% had invasive tests for screening indications. Colonoscopy accounted for 41% of all invasive tests for screening indications. Women were more likely to receive fecal occult blood test screening (OR 1.18; 95%CI 1.15, 1.21 and less likely to receive invasive tests for screening indications than men (OR 0.80, 95%CI 0.77, 0.83. Whites were more likely than other racial groups to receive any type of screening. Rural residents were more likely than urban residents to have fecal occult blood tests (OR 1.20, 95%CI 1.17, 1.23 but less likely to receive invasive tests for screening indications (OR 0.89; 95%CI 0.85, 0.93. Conclusion Reported use of fecal occult blood testing remains modest. Overall use of the more invasive tests for screening indications remains essentially unchanged, but there has been a shift toward increased use of screening colonoscopy. Significant demographic differences in screening utilization persist despite consistent insurance coverage.

A trend of steady decline in gastric cancer incidence rates is the effect of the increased standards of hygiene, conscious nutrition, and Helicobacter pylori eradication, which together constitute primary prevention. Avoidance of gastric cancer remains a priority. However, patients with higher risk should be screened for early detection and chemoprevention. Surgical resection enhanced by standardized lymphadenectomy remains the gold standard in gastric cancer therapy. This review briefly summarizes the most important aspects of gastric cancers, which include epidemiology, risk factors, classification, diagnosis, prevention, and treatment. The paper is mostly addressed to physicians who are interested in updating the state of art concerning gastric carcinoma from easily accessible and credible source.

    Full Text Available HER-2 is an important oncoprotein overexpressed in about 15–25% of breast cancers. We hypothesized that the ability of curcumin to downregulate HER-2 oncoprotein and inhibit the signal transduction pathway of PI3K/Akt, MAPK, and NF-κB activation may be important in the treatment of HER-2-overexpressed breast cancer. To examine the effect of curcumin on breast cancer cells, MCF-7, MDA-MB-231, MCF-10A, BT-474, and SK-BR-3-hr (a herceptin resistant strain from SK-BR-3 cells were used for in vitro analysis. The in vivo effect of curcumin on HER-2-overexpressed breast cancer was investigated with the HER-2-overexpressed BT-474 xenograft model. Cell growth, cell cycle change, the antimobility effect, signal transduction, and xenograft volume analysis between groups treated with herceptin and/or curcumin were tested. Curcumin decreased the cell growth of various breast cancer cell lines (MCF-7, MDA-MB-231, MCF-10A, BT-474, and SK-BR-3-hr. In Western blot analysis, the phosphorylation of Akt, MAPK, and expression of NF-κB were reduced in BT-474 cells, but not in SK-BR-3-hr cells, after treatment with herceptin. When treated with curcumin, the HER-2 oncoprotein, phosphorylation of Akt, MAPK and expression of NF-κB were decreased in both BT-474 and SK-BR-3-hr cells. In the BT-474 xenograft model, though not as much as herceptin, curcumin did effectively decrease the tumor size. The combination of curcumin with herceptin was not better than herceptin alone; however, the combination of taxol and curcumin had an antitumor effect comparable with taxol and herceptin. The results suggested that curcumin has potential as a treatment for HER-2-overexpressed breast cancer.

    Normally, thyroid cancer is a disease with a good prognosis, but about 30% the of tumors dedifferentiate and may finally develop into highly malignant thyroid carcinoma with a mean survival time of less than 8 months. Due to the loss of thyroid-specific functions associated with dedifferentiation. These tumors are inaccessible to standard therapeutic procedures such as radioiodine therapy and thyroxine-mediated thyrotropin suppression. Medullary thyroid carcinomas are also highly aggressive. Here, therapy is limited to surgery, and no alternative is left if patients do not respond to this standard procedures. Several novel approaches are currently being tested for the treatment of thyroid cancer. Many of them utilize methods of gene therapy: 1) reintroduction of the tumor suppressor p53; 2) suicide gene therapy; 3) antitumor immune response by expression of an adenovirus-delivered interleukin-2 (IL-2) gene; 4) immune response by DNA vaccination against the tumor marker calcitonin; 5) transduction of the thyroid sodium/iodine transporter gene to make tissues that do not accumulate iodide treatable by radioiodide therapy; 6) blocking of the expression of the oncogene c-myc by antisense oligonuleotides; 7) radioimmunotherapy by a radiolabelled antibody; 8) retinoic acid is used for a redifferentiation therapy, and 9) somatostatin.

    Every cancer survivor and his/her primary care provider should receive an individualized survivorship care plan (SCP) following curative treatment. Little is known regarding point-of-care utilization at primary care visits. We assessed SCP utilization in the clinical context of primary care visits. Primary care physicians and advanced practice providers (APPs) who had seen survivors following provision of an SCP were identified. Eligible primary care physicians and APPs were sent an online survey, evaluating SCP utilization and influence on decision-making at the point-of-care, accompanied by copies of the survivor's SCP and the clinic note. Eighty-eight primary care physicians and APPs were surveyed November 2016, with 40 (45%) responding. Most respondents (60%) reported discussing cancer or related issues during the visit. Information needed included treatment (66%) and follow-up visits, and the cancer team was responsible for (58%) vs primary care (58%). Respondents acquired this information by asking the patient (79%), checking oncology notes (75%), the SCP (17%), or online resources (8%). Barriers to SCP use included being unaware of the SCP (73%), difficulty locating it (30%), and finding needed information faster via another mechanism (15%). Despite largely not using the SCP for the visit (90%), most respondents (61%) believed one would be quite or very helpful for future visits. Most primary care visits included discussion of cancer or cancer-related issues. SCPs may provide the information necessary to deliver optimal survivor care but efforts are needed to reduce barriers and design SCPs for primary care use.

    The aim of the study was to identify risk factors associated with postoperative urinary tract infections (UTIs) following hysterectomy-based surgical staging in women with endometrial cancer. This is a retrospective study utilizing an institutional database (2008-2016) of stage I-IV endometrial cancer cases that underwent hysterectomy-based surgery. UTIs occurring within a 30-day time period after surgery were examined and correlated to patient clinico-pathological demographics. UTIs were observed in 44 (6.4%, 95% confidence interval 4.6-8.2) out of 687 cases subsequent to the diagnosis of endometrial cancer. UTI cases were significantly associated with obesity, advanced stage, prolonged operative time, hysterectomy type, pelvic lymphadenectomy, non-β-lactam antibiotics, and intraoperative urinary tract injury (all, p Urinary tract infections are common in women following surgical treatment for women with endometrial cancer with risk factors being a prolonged surgical time, radical hysterectomy, and non-guideline perioperative anti-microbial agent use. Consideration of prophylactic anti-microbial agent use in a high-risk group of postoperative urinary tract infection merits further investigation.

    The utilization of radiation to sludge treatment has been studied as a case study of the utilization of radiation to environmental protection by the society for the utilization of radiation in Japan Atomic Industrial Forum Inc., and the result is presented in this paper. The examined radiation sources to sterilize sludge were γ-ray and electron beam, and sludge was irradiated in the forms of slurry or cake. Four treatment conditions by the combination of the radiation sources and the sludge conditions were examined. From the examined results, it was estimated that in the case one (γ-ray and slurry), the output of 25 kW or 1.6 million curie was required for the sludge treatment capacity of 250 tons/day, in the case two (electron beam and slurry), an accelerator of 20 mA or 60 mA was required for the capacity of 250 or 750 tons/day, respectively, in the case three (γ-ray and cake), a radiation source of 0.6 million curie was required for the capacity of 50 tons/day, and in the case four (electron beam and cake), an accelerator of 4 mA or 12 mA was required for the capacity of 50 tons/day or 150 tons/day.

    Despite the substantial prevalence of alcohol use disorders (AUDs), prior research indicates that most people with AUDs never utilize either formal or informal treatment services. Several prior studies have examined the characteristics of individuals with AUDs who receive treatment; however, limited longitudinal data are available on the predictors of receiving AUD services in treatment-naive individuals with AUDs. This study utilized data from the National Epidemiological Survey on Alcohol and Related Conditions (NESARC) to identify adults in Wave 1 who met criteria for an AUD within the last 12 months and reported no prior lifetime alcohol treatment (N = 2760). These individuals were surveyed again at Wave 2, approximately 3-4 years later (N = 2170). This study examined the Wave 1 demographic and psychiatric conditions that were associated with receipt of AUD treatment services between Waves 1 and 2. In multivariable analyses, use of AUD treatment services between Waves 1 and 2 was significantly more likely among those who were male, non-Caucasian, younger, had lower income, and who had health insurance. Additionally, those who met criteria for a baseline drug use disorder, anxiety disorder or a personality disorder were more likely to receive AUD treatment. Treatment was more often utilized in those who had more severe baseline psychopathology and in those with fewer economic resources. These findings highlight the need to broaden the types of care available to individuals with AUDs to increase the appeal of AUD services. Published by Elsevier Ireland Ltd.

  20. Axillary lymph node dissection for breast cancer utilizing Harmonic Focus®

    2011-08-01

    Full Text Available Abstract Background For patients with axillary lymph node metastases from breast cancer, performance of a complete axillary lymph node dissection (ALND is the standard approach. Due to the rich lymphatic network in the axilla, it is necessary to carefully dissect and identify all lymphatic channels. Traditionally, these lymphatics are sealed with titanium clips or individually sutured. Recently, the Harmonic Focus®, a hand-held ultrasonic dissector, allows lymphatics to be sealed without the utilization of clips or ties. We hypothesize that ALND performed with the Harmonic Focus® will decrease operative time and reduce post-operative complications. Methods Retrospective review identified all patients who underwent ALND at a teaching hospital between January of 2005 and December of 2009. Patient demographics, presenting pathology, treatment course, operative time, days to drain removal, and surgical complications were recorded. Comparisons were made to a selected control group of patients who underwent similar surgical procedures along with an ALND performed utilizing hemostatic clips and electrocautery. A total of 41 patients were included in this study. Results Operative time was not improved with the use of ultrasonic dissection, however, there was a decrease in the total number of days that closed suction drainage was required, although this was not statistically significant. Complication rates were similar between the two groups. Conclusion In this case-matched retrospective review, there were fewer required days of closed suction drainage when ALND was performed with ultrasonic dissection versus clips and electrocautery.

    The purpose of this study is to identify enabling factors for treatment utilization for alcohol-related problems, and to evaluate how enabling factors vary by need for treatment, among two samples of Mexican American adults. These two distinct samples included 2,595 current and former drinkers (one sample included 787 U.S./Mexico border residents; the other sample included 740 Mexican Americans living in U.S. cities not proximal to the border). Need for treatment (alcohol disorder severity) and (male) gender were the primary correlates of treatment utilization; and there was no moderation in the enabling factors by need for treatment as "enablers" of utilization. Further theoretical and empirical research is necessary to determine which mechanisms are driving disparities in treatment utilization across racial/ethnic groups generally, and Hispanic national groups specifically.

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

    Purpose: To assess the preliminary feasibility of automated treatment planning verification system in cervical cancer IMRT pre-treatment dose verification. Methods: The study selected randomly clinical IMRT treatment planning data for twenty patients with cervical cancer, all IMRT plans were divided into 7 fields to meet the dosimetric goals using a commercial treatment planning system(PianncleVersion 9.2and the EclipseVersion 13.5). The plans were exported to the Mobius 3D (M3D)server percentage differences of volume of a region of interest (ROI) and dose calculation of target region and organ at risk were evaluated, in order to validate the accuracy automated treatment planning verification system. Results: The difference of volume for Pinnacle to M3D was less than results for Eclipse to M3D in ROI, the biggest difference was 0.22± 0.69%, 3.5±1.89% for Pinnacle and Eclipse respectively. M3D showed slightly better agreement in dose of target and organ at risk compared with TPS. But after recalculating plans by M3D, dose difference for Pinnacle was less than Eclipse on average, results were within 3%. Conclusion: The method of utilizing the automated treatment planning system to validate the accuracy of plans is convenientbut the scope of differences still need more clinical patient cases to determine. At present, it should be used as a secondary check tool to improve safety in the clinical treatment planning.

  4. Metabolic syndrome induced by anticancer treatment in childhood cancer survivors.

    Science.gov (United States)

    Chueh, Hee Won; Yoo, Jae Ho

    2017-06-01

    The number of childhood cancer survivors is increasing as survival rates improve. However, complications after treatment have not received much attention, particularly metabolic syndrome. Metabolic syndrome comprises central obesity, dyslipidemia, hypertension, and insulin resistance, and cancer survivors have higher risks of cardiovascular events compared with the general population. The mechanism by which cancer treatment induces metabolic syndrome is unclear. However, its pathophysiology can be categorized based on the cancer treatment type administered. Brain surgery or radiotherapy may induce metabolic syndrome by damaging the hypothalamic-pituitary axis, which may induce pituitary hormone deficiencies. Local therapy administered to particular endocrine organs directly damages the organs and causes hormone deficiencies, which induce obesity and dyslipidemia leading to metabolic syndrome. Chemotherapeutic agents interfere with cell generation and growth, damage the vascular endothelial cells, and increase the cardiovascular risk. Moreover, chemotherapeutic agents induce oxidative stress, which also induces metabolic syndrome. Physical inactivity caused by cancer treatment or the cancer itself, dietary restrictions, and the frequent use of antibiotics may also be risk factors for metabolic syndrome. Since childhood cancer survivors with metabolic syndrome have higher risks of cardiovascular events at an earlier age, early interventions should be considered. The optimal timing of interventions and drug use has not been established, but lifestyle modifications and exercise interventions that begin during cancer treatment might be beneficial and tailored education and interventions that account for individual patients' circumstances are needed. This review evaluates the recent literature that describes metabolic syndrome in cancer survivors, with a focus on its pathophysiology.

    Large-scale epidemiological studies have shown that the incidence of second primary thyroid cancer in subjects diagnosed and treated for testicular cancer is raised. This finding is strongly associated to treatment with radiotherapy and/or chemotherapy and it is explained by their mutagenic effect. On the other hand, inherited cancer susceptibility syndromes inducing both testicular and thyroid cancers denote that these tumours might share common genomic aberrations. We herein present our experience with three cases of metachronous development of thyroid cancer after diagnosis and treatment of testicular cancer in our tertiary cancer centre. Our case report contributes to the limited available literature on such findings and aims to raise awareness of the cancer physicians treating these particular tumour types. © The Author(s) 2016.

    Analyses of skin cancer procedures adjusted for population changes are needed. To describe trends in skin cancer-related biopsies and procedures in Medicare beneficiaries. An ecological study of Medicare claims for skin biopsies and skin cancer procedures in 2000 to 2015. Biopsies increased 142%, and skin cancer procedures increased 56%. Mohs micrographic surgery (MMS) utilization increased on the head/neck, hands/feet, and genitalia (increasing from 11% to 27% of all treatment procedures) but was low on the trunk/extremities (increasing from 1% to 4%). Adjusted for increased Medicare enrollment (+36%) between 2000 and 2015, the number of biopsies and MMS procedures performed per 1000 beneficiaries increased (from 56 to 99 and from 5 to 15, respectively), whereas the number of excisions and destructions changed minimally (from 18 to 16 and from 19 to 18, respectively). Growth in biopsies and MMS procedures slowed between each time period studied: 4.3 additional biopsies per year and 0.9 additional MMS procedures per year per 1000 beneficiaries between 2000 and 2007, 2.2 and 0.5 more between 2008 and 2011, and 0.5 and 0.3 more between 2012 and 2015, respectively. Medicare claims-level data do not provide patient-level or nonsurgical treatment information. The increased number of skin cancer procedures performed was largely the result of Medicare population growth over time. MMS utilization increased primarily on high- and medium-risk and functionally and cosmetically significant locations where tissue sparing and maximizing cure are critical.

    Cognitive decline is common among older adults with cancer. The present study aimed to investigate the impact of cognitive decline on health utility value in older adults suffering from cancer. Consecutive patients aged 65 years or older with a primary diagnosis of malignant lymphoma or multiple myeloma were recruited. Patients were asked to complete the EuroQoL-5 (EQ-5D) scale to measure health utility and the Mini-Mental State Examination to assess cognitive decline. The potential impact of cognitive decline was investigated with univariate analysis. A multivariate regression analysis was conducted to control for potential confounding factors. Complete data were obtained from 87 patients, 29% of whom had cognitive decline. The mean ± SE EQ-5D score for patients with cognitive decline was significantly lower than that for those without cognitive decline (0.67 ± 0.04 vs 0.79 ± 0.03, t = 2.38, P = 0.02). However, multiple regression analysis showed that cognitive decline was not significantly associated with EQ-5D scores. Female sex and lower performance scores (worse physical condition) were significantly associated with EQ-5D scores. Cognitive decline may be involved in decreased health utility value in older adult patients with cancer. However, this effect does not seem to be independent, and the patient's physical condition may be a relevant confounding factor. © 2016 The Authors.

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

    Increasing numbers of long-term cancer survivors face important treatment related adverse effects. Cancer treatment induced metabolic syndrome (CTIMetS) is an especially prevalent and harmful condition. The aetiology of CTIMetS likely differs from metabolic syndrome in the general population, but effective treatment and prevention methods are probably similar. In this review, we summarize the potential mechanisms leading to the development of CTIMetS after various types of cancer treatment. Furthermore, we propose a safe and accessible method to treat or prevent CTIMetS through lifestyle change. In particular, we suggest that a lifestyle intervention and optimization of energy balance can prevent or mitigate the development of CTIMetS, which may contribute to optimal survivorship care.

    2017-01-01

    To analyze the utilization and fractionation of extreme hypofractionation via stereotactic body radiotherapy (SBRT) in the treatment of prostate cancer. Data was analyzed on men diagnosed with localized prostate cancer between 2004–2012 and treated with definitive-intent radiation therapy, as captured in the National Cancer Database. This database is a hospital-based registry that collects an estimated 70% of all diagnosed malignancies in the United States. There were 299,186 patients identified, of which 4,962 (1.7%) were identified as receiving SBRT as primary treatment. Of those men, 2,082 had low risk disease (42.0%), 2,201 had intermediate risk disease (44.4%), and 679 had high risk disease (13.7%). The relative utilization of SBRT increased from 0.1% in 2004 to 4.0% in 2012. Initially SBRT was more commonly used in academic programs, though as time progressed there was a shift to favor an increased absolute number of men treated in the community setting. Delivery of five separate treatments was the most commonly utilized fractionation pattern, with 4,635 patients (91.3%) receiving this number of treatments. The most common dosing pattern was 725 cGy × 5 fractions (49.6%) followed by 700 cGy × 5 fractions (21.3%). Extreme hypofractionation via SBRT is slowly increasing acceptance.

As further long-term data regarding the safety and efficacy emerges, the relative utilization of this modality is expected to continue to increase

    To analyze the utilization and fractionation of extreme hypofractionation via stereotactic body radiotherapy (SBRT) in the treatment of prostate cancer. Data was analyzed on men diagnosed with localized prostate cancer between 2004–2012 and treated with definitive-intent radiation therapy, as captured in the National Cancer Database. This database is a hospital-based registry that collects an estimated 70% of all diagnosed malignancies in the United States. There were 299,186 patients identified, of which 4,962 (1.7%) were identified as receiving SBRT as primary treatment. Of those men, 2,082 had low risk disease (42.0%), 2,201 had intermediate risk disease (44.4%), and 679 had high risk disease (13.7%). The relative utilization of SBRT increased from 0.1% in 2004 to 4.0% in 2012. Initially SBRT was more commonly used in academic programs, though as time progressed there was a shift to favor an increased absolute number of men treated in the community setting. Delivery of five separate treatments was the most commonly utilized fractionation pattern, with 4,635 patients (91.3%) receiving this number of treatments. The most common dosing pattern was 725 cGy × 5 fractions (49.6%) followed by 700 cGy × 5 fractions (21.3%). Extreme hypofractionation via SBRT is slowly increasing acceptance. Currently 700-725 cGy × 5 fractions appears to be the most commonly employed scheme. As further long-term data regarding the safety and efficacy emerges, the relative utilization of this modality is expected to continue to increase.

    Full Text Available Abstract Background This is a long-term follow-up clinical study of adolescents and adults, survivors of childhood cancer. We evaluate and analyze the late somatic sequelae of childhood cancer treatment. Many such studies are susceptible to a strong selection bias, i.e., they employ a limited non-systematic sample of patients, based on a clinical hospital that provided the cancer treatment or performed the follow-up. To address the issue of selection bias, we perform here an analysis of late sequelae on a systematic database of the entire population of the children treated for cancer in Slovenia. Due to the specifics of cancer treatment procedures in Slovenia, they have all been treated and followed-up in the same clinic. Methods The data are based on the centralized registry of cancer patients in Slovenia and present a controlled and homogeneous collection. Late sequelae are evaluated following a modified CTCAE, i.e., the National Cancer Institute’s Common Terminology Criteria for Adverse Events version 3.0. We use survival analysis method to estimate the incidence of and risk for late sequelae, where the time variable is measured in years from the diagnosis date, while we follow the event of incidence of late sequelae scored other than none. Survival analysis is performed using KaplanMeier estimator and Cox regression model. Results The incidence of mild, moderate, or severe late sequelae of childhood cancer treatment significantly decreased from 75% in the group of patients diagnosed before 1975 to 55% for those diagnosed after 1995. The Cox regression analysis of the risk factors for the incidence of late sequelae identifies three significant factors: treatment modalities, age at diagnosis, and primary diagnosis. Conclusions The change of treatment modalities in terms of replacement of surgery and radiotherapy with chemotherapy is the main reason for the decrease of the incidence and the risk for late sequelae of childhood cancer treatment

    Full Text Available Abstract Background Self-reported information is an important tool for collecting clinical information for epidemiologic studies and in clinical settings where electronic medical records are not employed and shared. Methods Using data collected from the Shanghai Breast Cancer Survival Study (SBCSS, a population-based, prospective cohort study of 5,042 women diagnosed with breast cancer in Shanghai, China, we compared the concordance of patient questionnaire responses to a survey administered approximately 6 months after cancer diagnosis with medical chart information obtained from the diagnostic hospitals for several disease and treatment-related variables. Results Of 5,042 SBCSS participants, medical chart information was available for 4,948 women (98.1%. Concordance between patient self-reported and medical chart information was high for the majority of disease-related variables, including: diagnosing hospital (agreement: 98.7%, kappa: 0.99, type of surgery conducted (94.0%, 0.53, ER/PR status (94.5%, 0.91, and tumor position (98.2%, 0.97, as well as for important calendar dates, such as date of diagnosis, surgery, and first chemotherapy treatment. The 10 most commonly used chemotherapeutic drugs were all reported with agreement rates of at least 82%, with associated kappa values that ranged from 0.41 for calcium folinate to 0.76 for vinorelbine. Conclusions Our study found high validity for patient self-reported information for a variety of disease and treatment-related variables, suggesting the utility of self-reports as an important source of clinical information for both epidemiological research and patient care.

    Second malignant neoplasms, cardiovascular disease, neurotoxicity and ototoxicity, pulmonary complications, hypogonadism, and nephrotoxicity are potentially life-threatening long-term complications of testicular cancer and its therapy. This article describes the pathogenesis, risks, and management of these late effects experienced by long-term testicular cancer survivors, who are defined as individuals who are disease free 5 years or more after primary treatment. Testicular cancer survivors should follow applicable national guidelines for cancer screening and management of cardiovascular disease risk factors. In addition, health care providers should capitalize on the time of cancer diagnosis as a teachable moment to introduce and promote lifestyle changes. Copyright © 2015 Elsevier Inc.

    Objective Considering the increasing number of treatment options for metastatic breast cancer (MBC), it is important to develop high-quality methods to assess the cost-effectiveness of new anti-cancer drugs. This study aims to develop a global economic model that could be used as a benchmark for the economic evaluation of new therapies for MBC. Methods The Global Pharmacoeconomics of Metastatic Breast Cancer (GPMBC) model is a Markov model that was constructed to estimate the incremental cost per quality-adjusted life years (QALY) of new treatments for MBC from a Canadian healthcare system perspective over a lifetime horizon. Specific parameters included in the model are cost of drug treatment, survival outcomes, and incidence of treatment-related adverse events (AEs). Global parameters are patient characteristics, health states utilities, disutilities, and costs associated with treatment-related AEs, as well as costs associated with drug administration, medical follow-up, and end-of-life care. The GPMBC model was tested and validated in a specific context, by assessing the cost-effectiveness of lapatinib plus letrozole compared with other widely used first-line therapies for post-menopausal women with hormone receptor-positive (HR+) and epidermal growth factor receptor 2-positive (HER2+) MBC. Results When tested, the GPMBC model led to incremental cost-utility ratios of CA$131 811 per QALY, CA$56 211 per QALY, and CA$102 477 per QALY for the comparison of lapatinib plus letrozole vs letrozole alone, trastuzumab plus anastrozole, and anastrozole alone, respectively. Results of the model testing were quite similar to those obtained by Delea et al., who also assessed the cost-effectiveness of lapatinib in combination with letrozole in HR+/HER2 + MBC in Canada, thus suggesting that the GPMBC model can replicate results of well-conducted economic evaluations. Conclusions The GPMBC model can be very valuable as it allows a quick and valid assessment of the cost

    To use the critical social theory as a framework to analyze the oppression of Jordanian women with early stage breast cancer in the decision-making process for surgical treatment and suggest strategies to emancipate these women to make free choices. This is a discussion paper utilizing the critical social theory as a framework for analysis. The sexist and paternalistic ideology that characterizes Jordanian society in general and the medical establishment in particular as well as the biomedical ideology are some of the responsible ideologies for the fact that many Jordanian women with early stage breast cancer are denied the right to choose a surgical treatment according to their own preferences and values. The financial and political power of Jordanian medical organizations (e.g., Jordan Medical Council), the weakness of nursing administration in the healthcare system, and the hierarchical organization of Jordanian society, where men are first and women are second, support these oppressing ideologies. Knowledge is a strong tool of power. Jordanian nurses could empower women with early stage breast cancer by enhancing their knowledge regarding their health and the options available for surgical treatment. To successfully emancipate patients, education alone may not be enough; there is also a need for health care providers’ support and unconditional acceptance of choice. To achieve the aim of emancipating women with breast cancer from the oppression inherent in the persistence of mastectomy, Jordanian nurses need to recognize that they should first gain greater power and authority in the healthcare system.

    Treatment of esophagus cancer taking into account frequency of metastatic spread in lymph nodes of different esophagus sections is presented. In the case of metastases in retroperitoneal lymph nodes esophagus resection is useless and radiation therapy is of palliation character. After removal of metastases in paracardial lymph nodes and nodes of the lesser omentum the patients should be considered as a group for provesory radical surgery, radiation and combined treatment for subsequent evaluation of the treatment expediency as more data are accumulated. In cases of middle mediastinum cancer of the lower third of esophagus all lymph nodes along esophagus below bifurcation of the trachea should be subjected to surgical (radiation) treatment. In the case of median third of esophagus cancer - the nodes along the entire thoracic part of the esophagus. For radiation therapy of the upper third of the esophagus irradiation fields should comprise lymph nodes along the esophagus above bifurcation of the trachea and cervicosubclavicular lymph nodes

    Juvenal, Guillermo J.

    2006-01-01

    Undifferentiated thyroid cancer, which accounts for about 5-10% of thyroid cancer cases, is a very aggressive tumor with no effective treatment, since it lacks iodine uptake and does not respond to radio or chemotherapy. The prognosis of these patients is bad, due to the rapid growth of the tumor and the early development of metastasis. Oncogenes and tumor suppressor genes are involved in the genetic changes that underlie thyroid cancer, as all kinds of tumors. The characterization of these proteins is being exploited to delineate new therapeutic strategies for the treatment of this cancer. This work is focused on those compounds or therapeutic approaches that are being used in clinical essays or in animal models. (author) [es

    2018-04-01

    Colorectal cancer is one of the most common malignant tumors in China. In 2012 one million thirty six thousand cases of colorectal cancer were diagnosed all over the world, two hundred fifty three thousand cases were diagnosed in China (accounted for 18.6%). China has the largest number of new cases of colorectal cancer in the world. Colorectal cancer has becoming a serious threat of Chinese residents' health. In 2010, the National Ministry of Health organized colorectal cancer expertise of the Chinese Medical Association to write the "Chinese Protocol of Diagnosis and Treatment of Colorectal Cancer" (2010edition), and publish it publicly. In recent years, the National Health and Family Planning Commission has organized experts to revised the protocol 2 times: the first time in 2015, the second time in 2017. The revised part of "Chinese Protocol of Diagnosis and Treatment of Colorectal Cancer" (2017 edition) involves new progress in the field of imaging examination, pathological evaluation, surgery, chemotherpy and radiotherapy. The 2017 edition of the protocol not only referred to the contents of the international guidelines, but also combined with the specific national conditions and clinical practice in China, and also included many evidence-based clinical data in China recently. The 2017 edition of the protocol would further promote the standardization of diagnosis and treatment of colorectal cancer in China, improve the survival and prognosis of patients, and benefit millions of patients with colorectal cancer and their families.

    Purpose: To compile and review data on radiation proctopathy in the treatment of prostate cancer with respect to epidemiology, clinical manifestations, pathogenesis, risk factors, and treatment. Methods: Medical literature databases including PubMed and Medline were screened for pertinent reports, and critically analyzed for relevance in the scope of our purpose. Results: Rectal toxicity as a complication of radiotherapy has received attention over the past decade, especially with the advent of dose-escalation in prostate cancer treatment. A number of clinical criteria help to define acute and chronic radiation proctopathy, but lack of a unified grading scale makes comparing studies difficult. A variety of risk factors, related to either radiation delivery or patient, are the subject of intense study. Also, a variety of treatment options, including medical therapy, endoscopic treatments, and surgery have shown varied results, but a lack of large randomized trials evaluating their efficacy prevents forming concrete recommendations. Conclusion: Radiation proctopathy should be an important consideration for the clinician in the treatment of prostate cancer especially with dose escalation. With further study of possible risk factors, the advent of a standardized grading scale, and more randomized trials to evaluate treatments, patients and physicians will be better armed to make appropriate management decisions

    2016-01-01

    Pancreatic cancer is one of the most lethal cancers among all malignances, with a median overall survival of cancers harbor a variety of genetic alternations that render it difficult to treat even with targeted therapy. Recent studies revealed that pancreatic cancers are highly enriched with a cancer stem cell (CSC) population, which is resistant to chemotherapeutic drugs, and therefore escapes chemotherapy and promotes tumor recurrence. Cancer cell epithelial to mesenchymal transition (EMT) is highly associated with metastasis, generation of CSCs, and treatment resistance in pancreatic cancer. Reviewed here are the molecular biology of pancreatic cancer, the major signaling pathways regulating pancreatic cancer EMT and CSCs, and the advancement in current clinical and experimental treatments for pancreatic cancer.

    To explore gender differences in bladder cancer treatment decision making.
. Secondary qualitative analysis of interview transcripts.
. One multidisciplinary genitourinary oncology clinic (Dana-Farber Cancer Institute) and two urology clinics (Brigham and Women's Hospital and Beth Israel Deaconess Medical Center) in Boston, MA.
. As part of the original study, 45 men and 15 women with bladder cancer participated in individual interviews. Participants were primarily Caucasian, and most had at least some college education.
. Word frequency reports were used to identify thematic differences between the men's and women's statements. Line-by-line coding of constructs prevalent among women was then performed on all participants in NVivo 9. Coding results were compared between genders using matrix coding queries.
. The role of family in the decision-making process was found to be a dominant theme for women but not for men. Women primarily described family members as facilitators of bladder cancer treatment-related decisions, but men were more likely to describe family in a nonsupportive role.
. The results suggest that influences on the decision-making process are different for men and women with bladder cancer. Family may play a particularly important role for women faced with bladder cancer treatment-related decisions.
. Clinical nurses who care for individuals with bladder cancer should routinely assess patients' support systems and desired level of family participation in decision making. For some people with bladder cancer, family may serve as a stressor. Nurses should support the decision-making processes of all patients and be familiar with resources that can provide support to patients who do not receive it from family.

  13. Pulsed Dose Rate (PDR - BT) brachytherapy in treatment of breast cancer

    Skowronek, J.

    2007-01-01

    Breast conserving surgery (BCS) and radiotherapy (EBRT) of the conserved breast became widely accepted in the last decades for the treatment of early invasive breast cancer. The standard technique of RT after breast conservation is to treat the whole breast up to a total dose of 45 to 50 Gy. Initially brachytherapy for breast cancer was used in addition of external radiation to boost a portion of the breast to higher doses. However, over the past 10 years, the application of brachytherapy in breast cancer has changed. In early stage breast cancer, research has shown that the area that requires radiation treatment to prevent the cancer from returning is the breast tissue that surrounds the area where the initial cancer was removed. Because this typically includes only a part of the breast, brachytherapy is now being used to treat the targeted portion of the breast and as a result allows accelerated delivery of the radiation dose so that treatment is completed in four to five days. Another indications for PDR - BT as a part of treatment in locally advanced breast cancer or as a palliative treatment are discussed in the paper, too. Preliminary results with PDR - BT boost technique are promising. However, more experience and longer follow-up are required to define whether these methods might improve local tumor control for breast cancer patients. In this article the current status, indications, technical aspects and published results of PDR brachytherapy (PDR - BT) in breast cancer treatment are reviewed. (author)

    African American breast cancer survivors (AABCS) have a lower survival rate across all disease stages (79 %) compared with White survivors (92 %) and often have more aggressive forms of breast cancer requiring multimodality treatment, so they could experience a larger burden of post-treatment quality of life (QOL) problems. This paper reports a comprehensive assessment of the number, severity, and domains of problems faced by AABCS within 5 years after treatment completion and identifies subgroups at risk for these problems. A population-based random sample was obtained from the Pennsylvania Cancer Registry of African American females over 18 years of age who completed primary treatment for breast cancer in the past 5 years. A mailed survey was used to document survivorship problems. Two hundred ninety-seven AABCS completed the survey. The median number of survivor problems reported was 15. Exploratory factor analysis of the problem scale revealed four domains: emotional problems, physical problems, lack of resources, and sexuality problems. Across problem domains, younger age, more comorbid conditions, and greater medical mistrust were risk factors for more severe problems. The results demonstrated that AABCS experienced significant problem burden in the early years after diagnosis and treatment. In addition to emotional and physical problem domains that were documented in previous research, two problem domains unique to AABCS included lack of resources and sexuality concerns. At risk groups should be targeted for intervention. The study results reported in this manuscript will inform future research to address problems of AABCS as they make the transition from cancer patient to cancer survivor.

    Malnutrition as assessed with the use of body-composition measurements is a poorly understood short- and long-term complication of childhood cancer. We aimed to evaluate the body composition of 2 childhood cancer cohorts as follows: 1) children currently undergoing cancer treatment and 2) childhood cancer survivors. We also aimed to compare the prevalence of obesity and undernutrition between the cancer groups and investigate the impact of cancer type on body composition. Eighty-two children during the treatment of cancer and 53 childhood cancer survivors were involved in the study. Height, weight, body cell mass, percentage of fat, fat mass index, and fat-free mass index were assessed. Subjects were compared with age- and sex-matched healthy controls. The on-treatment group had a higher percentage of fat (P = 0.0001) and fat mass index (P = 0.0001) and a significantly lower body cell mass index (P = 0.0001) and fat-free mass index (P = 0.003) than did matched controls. The survivor group had a significantly higher percentage of fat (P = 0.03) and fat mass index (P = 0.04) and significantly lower body cell mass index (P = 0.0001) than did matched controls. The prevalence of undernutrition was high in both groups with 48% (95% CI: 36%, 60%) of the on-treatment group and 53% (95% CI: 40%, 66%) of the survivors considered undernourished. According to the percentage of fat cutoffs, significantly more on-treatment patients were obese (55%; 95% CI: 40%, 60%) than were survivors (26%; 95% CI: 14%, 38%) (P = 0.005). There were no statistically significant differences in body composition between cancer types in either the on-treatment or the survivor group. Overnutrition and undernutrition are major concerns in the short and long term for children with cancer. Children treated for cancer have increased fat mass and decreased body cell mass, which are evident during treatment and in survivorship.

    High frequency of cancer in older people and the improvements in life expectancy do not allow older age to be a barrier to treatment. The age is one of the risk factors for breast cancer development, one third of all cases occur in women older than 70 years. To provide an overview of the available information on the main issues in the field of surgery, radiotherapy and medical approaches to the treatment of breast cancer in the elderly. The author discusses the treatment of breast cancer in the elderly, based on the data of literature. The assessment of any patient is the first step in the treatment process, performance status is more important than age. In older women a correct evaluation includes not only the basic medical history and the cancer staging, but also a detailed assessment of health and environment that may interfere with the therapeutic approach of the patient. Age is not a limitation for surgery, without any comorbidity it is safe, and operative mortality is low. The body self-image is important for most old women, they also wish to keep their breasts, so a conservative surgery and adjuvant radiotherapy should be offered to all, as long as the stage permits it. The selection of patients who are candidates for axillary dissection is based on selective lymph sentinel node technique which provides an optimal nodal staging with a minimal morbidity. The results of radiotherapy are as good as in younger patients, elderly women tolerate radiotherapy well. The inability to travel to the radiation facility is often the reason for omitting the radiation treatment and to choose a modified mastectomy. A promising alternative to the standard radiation treatment is the concept of intraoperative radiotherapy. Breast cancer in the elderly women is more likely to be well differentiated tumour, containing oestrogen and progesterone receptors. Based on these favourable prognostic factors, endocrine therapy is the standard treatment in adjuvant and metastatic setting

    An ongoing debate over the last two decades has focused on whether fertility treatment in women may lead to an increased risk of developing uterine cancer over a period of time. Uterine cancer (including mainly endometrial carcinoma and the less common uterine sarcoma) is the commonest reproductive tract cancer and the fourth commonest cancer in women in the UK. Our objective was to assess the association between fertility drugs used in the treatment of female infertility (both as an independent therapy and during in vitro fertilization cycles) and the development of uterine cancer. A literature search was performed using Medline, Embase, Cochrane Library and Google Scholar databases for comparative studies until December 2014 to investigate a clinical significance of fertility treatment on the incidence of developing uterine cancer. General and MESH search headings, as well as the 'related articles' function were applied. All comparative studies of 'fertility treatment' versus 'non-fertility treatment' reporting the incidence of uterine cancer as an outcome were included. Uterine cancer incorporated the following terms: uterine cancer, uterine body tumours, uterine sarcomas and endometrial cancers. The primary outcome of interest was the uterine cancer incidence in all 'fertility treatment' versus 'non-fertility treatment' patient groups. Secondary outcomes of interest were: (a) uterine cancer incidence in 'IVF' versus 'non-IVF' patient groups; and (b) uterine cancer incidence according to type of fertility drug used. Odds ratio was the summary statistic. Random-effects modelling, graphical exploration and sensitivity analysis were used to evaluate the consistency of the calculated treatment effect. We included six studies in our final analysis, which comprised 776,224 patients in total. Of these, 103,758 had undergone fertility treatment and 672,466 had not. There was 100% agreement between the two reviewers regarding the data extraction. All the studies

Existing bleeds can also be exacerbated by medications such as bevacizumab, nonsteroidal anti-inflammatory drugs (NSAIDs), and anticoagulants. Patients may develop acute catastrophic bleeding, episodic major bleeding, or low-volume oozing. Bleeding may present as bruising, petechiae, epistaxis, hemoptysis, hematemesis, hematochezia, melena, hematuria, or vaginal bleeding. Therapeutic intervention for bleeding should start by establishing goals of care, and treatment choice should be guided by life expectancy and quality of life. Careful thought should be given to discontinuation of medications and reversal of anticoagulation. Interventions to stop or slow bleeding may include systemic agents or transfusion of blood products. Noninvasive local treatment options include applied pressure, dressings, packing, and radiation therapy. Invasive local treatments include percutaneous embolization, endoscopic procedures, and surgical treatment.

    Breast cancer is one of the most common cancers among women around the world. It accounts for 22.9% of all the cancers and 18% of all female cancers in the world. One million new cases of breast cancer are diagnosed every year. Pakistan has more alarming situation with 90,000 new cases and ending up into 40,000 deaths annually. The risk factor for a female to develop breast cancer as compared with male is 100 : 1. The traditional way of treatment is by surgery, chemotherapy or radiotherapy. Advanced breast cancer is very difficult to treat with any of the traditional treatment options. A new treatment option in the form of gene therapy can be a promising treatment for breast cancer. Gene therapy provides treatment option in the form of targeting mutated gene, expression of cancer markers on the surface of cells, blocking the metastasis and induction of apoptosis, etc. Gene therapy showed very promising results for treatment of various cancers. All this is being trialed, experimented and practiced outside of Pakistan. Therefore, there is an immense need that this kind of work should be started in Pakistan. There are many good research institutes as well as well-reputed hospitals in Pakistan. Presently, there is a need to develop collaboration between research institutes and hospitals, so that the basic work and clinical trials can be done to treat breast cancer patients in the country. This collaboration will prove to be very healthy and will not only strength research institute but also will be very beneficial for cancer patients. (author)

    Plasma oncology is a relatively new field of research. Recent developments have indicated that cold atmospheric plasma (CAP) technology is an interesting new therapeutic approach to cancer treatment. In this study, p53 wildtype (LoVo) and human p53 mutated (HT29 and SW480) colorectal cancer cells were treated with the miniFlatPlaSter - a device particularly developed for the treatment of tumor cells - that uses the Surface Micro Discharge (SMD) technology for plasma production in air. The present study analyzed the effects of plasma on colorectal cancer cells in vitro and on normal colon tissue ex vivo. Plasma treatment had strong effects on colon cancer cells, such as inhibition of cell proliferation, induction of cell death, and modulation of p21 expression. In contrast, CAP treatment of murine colon tissue ex vivo for up to 2 min did not show any toxic effect on normal colon cells compared to H2O2 positive control. In summary, these results suggest that the miniFlatPlaSter plasma device is able to kill colorectal cancer cells independent of their p53 mutation status. Thus, this device presents a promising new approach in colon cancer therapy.

    2013-09-01

    Full Text Available In breast cancer patients, bone is the most common site of metastases. Medical therapies are the basic therapy to prevent distant metastases and recurrence and to cure them. Radiotherapy has a primary role in pain relief, recalcification and stabilization of the bone, as well as the reduction of the risk of complications (e.g., bone fractures, spinal cord compression. Bisphosphonates, as potent inhibitors of osteoclastic-mediated bone resorption are a well-established, standard-of-care treatment option to reduce the frequency, severity and time of onset of the skeletal related events in breast cancer patients with bone metastases. Moreover bisphosphonates prevent cancer treatment-induced bone loss. Recent data shows the anti-tumor activity of bisphosphonates, in particular, in postmenopausal women and in older premenopausal women with hormone-sensitive disease treated with ovarian suppression. Pain is the most frequent symptom reported in patients with bone metastases, and its prevention and treatment must be considered at any stage of the disease. The prevention and treatment of bone metastases in breast cancer must consider an integrated multidisciplinary approach.

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

    2011-04-01

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

    2015-09-01

    Presentation is reviewing the newest results obtained by researchers of A.J. Drexel Plasma Institute on direct application of non-thermal plasma for direct treatment of different types of cancer by means of specific stimulation of immune system in the frameworks of the so-called onco-immunotherapy. Especial attention is paid to analysis of depth of penetration of different plasma-medical effects, from ROS, RNS, and ions to special biological signaling and immune system related processes. General aspects of the plasma-stimulation of immune system are discussed, pointing out specific medical applications. Most of experiments have been carried out using nanosecond pulsed DBD at low power and relatively low level of treatment doses, guaranteeing non-damage no-toxicity treatment regime. The nanosecond pulsed DBD physics is discussed mostly regarding its space uniformity and control of plasma parameters relevant to plasma medical treatment, and especially relevant to depth of penetration of different plasma medical effects. Detailed mechanism of the plasma-induced onco-immunotherapy has been suggested based upon preliminary in-vitro experiments with DBD treatment of different cancer cells. Sub-elements of this mechanism related to activation of macrophages and dendritic cells, specific stressing of cancer cells and the immunogenic cell death (ICD) are to be discussed based on results of corresponding in-vitro experiments. In-vivo experiments focused on the plasma-induced onco-immunotherapy were carried out in collaboration with medical doctors from Jefferson University hospital of Philadelphia. Todays achievements and nearest future prospective of clinical test focused on plasma-controlled cancer treatment are discussed in conclusion.

    2014-06-01

    Purpose: Photo-dynamic therapy (PDT) is an effective treatment modality because of the preferential absorption of photosensitizing agent in tumor cells than in surrounding normal tissues. A limitation of PDT for cancer therapy is the finite penetration of laser light to activate the targeting agent in deep-seated tumors. Radio-dynamic therapy (RDT) is designed to overcome this problem by the combination of high-energy (up to 45MV) photon beams and photo/radio-sensitizers. This work investigates the feasibility of PDT for late-stage cancer patients who are no longer respond to conventional therapies available. Methods: The high-energy photon beams are generated using a LA45 RaceTrack Microtron (Top Grade Medical, Beijing, China). The targeting agent investigated is 5- aminolevulinic acid (5-ALA). Both in vitro cell lines and in vivo animal models have been used to investigate the mechanisms of RDT and its therapeutic effects and normal tissue toxicities. Oral 5-ALA (30-60 mg/kg) was administered 4-6 hours before the radiation treatment and the total radiation dose varied between 0.1-4.0Gy in 1-4 fractions. Clinical trials are initiated in China for late-stage cancer patients targeting both primary tumors utilizing localized therapies such as 3DCRT/IMRT and metastases using TBI. Results: There is clear correlation between the cell death and the 5-ALA concentration/radiation dose. The therapeutic effect of RDT is demonstrated using an animal model where the volume of parotid tumors for the RT only group continued to grow after 3Gy irradiation while the RDT group showed a complete response with the same radiation dose. The preliminary clinical results showed encouraging clinical outcome. Conclusion: RDT is a novel treatment technique that may be developed into an effective cancer treatment modality. Further studies on the mechanisms of RDT and its potential clinical applications are warranted.

    Following the increasing desire of many patients to keep the form and function of speech and swallowing, interstitial brachytherapy has become the main treatment for head and neck cancer. In addition, aged and physically handicapped patients who are refused general anesthesia have come to be referred to our clinic to receive less invasive and curative treatment. In the field of brachytherapy for head and neck cancers, less complicated and more superior treatment results have been achieved following the introduction of spacers, computer dosimetry and so on. As a result of these efforts, treatment results have come to fulfill the desire of patients and their families. During the past 43 years from 1962 to 2005, we have treated over 2, 100 patients of head and neck cancer including 850 with stage I·II oral tongue carcinoma by brachytherapy and acquired a lot of important and precious data including the treatment results, multiple primary cancers as well as radiation-induced cancers.

    2011-02-01

    Patients with gastrointestinal cancers are susceptible to nutritional deterioration which may be compounded by radiotherapy treatment toxicities. This study aimed to determine whether nutritional status at radiotherapy commencement or changes in nutritional status throughout radiotherapy were associated with treatment toxicity and outcomes in gastrointestinal cancer patients. Seventy-three gastrointestinal cancer patients receiving curative radiotherapy underwent medical record audits assessing body weight, radiotherapy toxicity, unplanned treatment breaks or hospital admissions and completion of prescribed treatment/s. Nutritional status was assessed in a subset of patients (n = 11) using the Patient-Generated Subjective Global Assessment tool. Seventy-five percent of patients lost weight throughout radiotherapy. Weight loss was significantly greater in patients experiencing unplanned radiotherapy breaks (-3.1% vs -1.6%, p nutritional status during radiotherapy (as measured by weight loss) may be associated with poorer short-term treatment outcomes in gastrointestinal cancer patients. Patient numbers were too small to definitively determine the effect of nutritional status at radiotherapy commencement or changes in nutritional status throughout radiotherapy (defined by PG-SGA) on treatment outcomes. Further research is required to investigate this in larger, longer-term studies. Copyright © 2010. Published by Elsevier Ltd.

    2017-05-01

    Early detection of skin cancer is essential to reducing morbidity and mortality from both melanoma and nonmelanoma skin cancers. Total-body skin examinations (TBSEs) may improve early detection of malignant melanomas (MMs) but are controversial due to the poor quality of data available to establish a mortality benefit from skin cancer screening. Total-body photography (TBP) promises to provide a way forward by lowering the costs of dermatologic screening while simultaneously leveraging technology to increase patient access to dermatologic care. Standardized TBP also offers the ability for dermatologists to work synergistically with modern computer technology involving algorithms capable of analyzing high-quality images to flag concerning lesions that may require closer evaluation. On a population level, inexpensive TBP has the potential to increase access to skin cancer screening and it has several specific applications in a military population. The utility of standardized TBP is reviewed in the context of skin cancer screening and teledermatology.

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

    The influence of parental socio-economic status on childhood cancer treatment outcome in low-income countries has not been sufficiently investigated. Our study examined this influence and explored parental experiences during cancer treatment of their children in an Indonesian academic hospital. Medical charts of 145 children diagnosed with cancer between 1999 and 2009 were reviewed retrospectively. From October 2011 until January 2012, 40 caretakers were interviewed using semi-structured questionnaires. Of all patients, 48% abandoned treatment, 34% experienced death, 9% had progressive/ relapsed disease, and 9% overall event-free survival. Prosperous patients had better treatment outcome than poor patients (Pfate or God (55%). Causes of cancer were thought to be destiny (35%) or God's punishment (23%). Alternative treatment could (18%) or might (50%) cure cancer. Most parents (95%) would like more information about cancer and treatment. More contact with doctors was desired (98%). Income decreased during treatment (55%). Parents lost employment (48% fathers, 10% mothers), most of whom stated this loss was caused by their child's cancer (84% fathers, 100% mothers). Loss of income led to financial difficulties (63%) and debts (55%). Treatment abandonment was most important reason for treatment failure. Treatment outcome was determined by parental socio-economic status. Childhood cancer survival could improve if financial constraints and provision of information and guidance are better addressed.

    To identify problems at different treatment points (early treatment, mid-treatment, early posttreatment, and late posttreatment) among women with ovarian cancer. Longitudinal and cross-sectional study design. An academic and community clinical cancer center in the Southeastern United States. Sixty-eight women with Stage I to IV ovarian cancer. Variables assessed included reported problems (physical, psychosocial, pain, marital, medical interaction), social support, optimism, and responses to open-ended questions. Analysis involved mixed models for longitudinal repeated measures and unpaired t tests and content analysis to describe responses to open-ended questions. Physical and psychosocial problems were greatest during early treatment and decreased throughout the treatment trajectory. Women with greater levels of social support and optimism at baseline had fewer problems over time. Women who did not have trouble paying for basics had fewer problems related to pain and psychological problems. Problems across all domains must be addressed throughout the treatment trajectory, even after chemotherapy has ended. Nurses are well positioned to refer women appropriately to social workers and clinical navigators across all domains of care and should consider systematic assessment of patient-reported problems as a routine form of practice.

    2010-03-01

    Cancer pain remains inadequately treated, despite internationally accepted management guidelines and a myriad of treatment options. Risk factors for undertreatment are reviewed, along with possible explanations. Recent studies documenting the scope of the problem as well as investigating solutions are discussed with clinical-practice recommendations outlined. Women over 65 years of age representative of a cultural minority, with earlier stage disease, cared for at home, and with high-school education or less are at highest risk of having uncontrolled cancer pain. Optimal treatment is impeded by patients' maladaptive beliefs, nonadherence, underreporting or miscommunication with caregivers; from a healthcare provider perspective, it may be due to inadequate assessment, documentation, knowledge, and communication. Emerging data support the vital influence of lay caregivers on appropriate pain management. Although home-education programs may decrease pain and improve quality of life, there are also less intensive approaches deliverable by individuals to holistically address pain. Prospective study of barriers to both delivery and receipt of adequate pain management is needed, as the majority of published literature is based on survey studies. Treatment must be individualized based on clinical circumstances and patient wishes, with the goal of maximizing function and quality of life.

    2017-07-01

    Cancer affects a growing proportion of the population as survival improves. The illness and its treatment brings a substantial burden of symptoms, including pain, anxiety, insomnia, and grief. Here, the uses of hypnosis in the treatment of these cancer-related problems will be reviewed. The utility of measuring hypnotizability in the clinical setting will be discussed. The current neurobiology of hypnotizability and hypnosis will be reviewed. Methods and results of using hypnosis for pain control in acute and chronic settings will be presented. Effects of hypnotic analgesia in specific brain regions associated with pain reduction, notably the dorsal anterior cingulate cortex and the somatosensory cortex, underlies its utility as a potent and side-effect free analgesic. Methods for helping those with cancer to better manage their anxiety, insomnia, and grief will be described. These involve facing disease-related stressors while dissociating the experience from somatic arousal. Given the serious complications of medications widely used to treat pain, anxiety, and insomnia, this article provides methods and an evidence base for wider use of techniques involving hypnosis in cancer care. Altering patients' perception of pain, disease-related stress, and anxiety can help change the reality of their life with cancer.

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

    Full Text Available Cancer treatment is often hindered by inadequate methods for diagnosing the disease or insufficient predictive capacity regarding therapeutic efficacy. Targeted cancer treatments, including Bcr-Abl and EGFR kinase inhibitors, have increased survival for some cancer patients but are ineffective in other patients. In addition, many patients who initially respond to targeted inhibitor therapy develop resistance during the course of treatment. Molecular analysis of cancer cells has emerged as a means to tailor treatment to particular patients. While DNA analysis can provide important diagnostic information, protein analysis is particularly valuable because proteins are more direct mediators of normal and diseased cellular processes. In this review article, we discuss current and emerging protein assays for improving cancer treatment, including trends toward assay miniaturization and measurement of protein activity.

  18. Enhancing the efficacy of cisplatin in ovarian cancer treatment – could arsenic have a role

    Full Text Available Abstract Ovarian cancer affects more than 200,000 women each year around the world. Most women are not diagnosed until the disease has already metastasized from the ovaries with a resultant poor prognosis. Ovarian cancer is associated with an overall 5 year survival of little more than 50%. The mainstay of front-line therapy is cytoreductive surgery followed by chemotherapy. Traditionally, this has been by the intravenous route only but there is more interest in the delivery of intraperitoneal chemotherapy utilizing the pharmaco-therapeutic advantage of the peritoneal barrier. Despite three large, randomized clinical trials comparing intravenous with intraperitoneal chemotherapy showing improved outcomes for those receiving at least part of their chemotherapy by the intraperitoneal route. Cisplatin has been the most active drug for the treatment of ovarian cancer for the last 4 decades and the prognosis for women with ovarian cancer can be defined by the tumor response to cisplatin. Those whose tumors are innately platinum-resistant at the time of initial treatment have a very poor prognosis. Although the majority of patients with ovarian cancer respond to front-line platinum combination chemotherapy the majority will develop disease that becomes resistant to cisplatin and will ultimately succumb to the disease. Improving the efficacy of cisplatin could have a major impact in the fight against this disease. Arsenite is an exciting agent that not only has inherent single-agent tumoricidal activity against ovarian cancer cell lines but also multiple biochemical interactions that may enhance the cytotoxicity of cisplatin including inhibition of deoxyribose nucleic acid (DNA repair. In vitro studies suggest that arsenite may enhance the activity of cisplatin in other cell types. Arsenic trioxide is already used clinically to treat acute promyelocytic leukemia demonstrating its safety profile. Further research in ovarian cancer is warranted to define

    This paper explains the outline of the present diagnosis and treatment of breast cancer essentially based on its therapeutic guideline by the Japan Breast Cancer Society (2005) and on authors' experiences. The diagnosis item contains the medical interview of patients, observatory and palpating examinations, mammography (for this, Japan-Breast Imaging Recording and Data System), ultrasonography (guideline for sonographic diagnosis of mammary gland, 2004), fine needle aspiration (FNA) or aspiration biopsy cytology, bases of triple test (palpation, mammography and FNA) for the cancer diagnosis, core needle biopsy, and mammotome biopsy of non-palpable calcified lesion. The treatment item contains the surgery involving conservation, sentinel lymph node biopsy (for this, lymphoscintigraphy with Tc-phytate is illustrated), radiofrequency ablation, adjuvant chemotherapy essentially using anthracycline and taxane, endocrinological therapy using tamoxifen, LH-RH analogues and aromatase inhibitors, and molecular target therapy with HER2 monoclonal antibody like trastuzumab. Recent progress of systemic therapy with medicals is remarkable, and the educational promotion of experts and medicare circumstances are concluded to be important. (R.T.)

    Women who have been treated for breast cancer are at risk for second breast cancers, such as ipsilateral recurrence or contralateral metachronous breast cancer. As the number of breast cancer survivors increases, interest in patient management and surveillance after treatment has also increased. However, post-treatment surveillance programs for patients with breast cancer have not been firmly established. In this review, we focus on the imaging modalities that have been used in post-treatment surveillance for patients with breast cancer, such as mammography, ultrasonography, magnetic resonance imaging, and positron emission tomography, the effectiveness of each modality for detecting recurrence, and how they can be applied to manage patients.

    Current cancer precision medicine strategies match therapies to static consensus molecular properties of an individual's cancer, thus determining the next therapeutic maneuver. These strategies typically maintain a constant treatment while the cancer is not worsening. However, cancers feature complicated sub-clonal structure and dynamic evolution. We have recently shown, in a comprehensive simulation of two non-cross resistant therapies across a broad parameter space representing realistic tumors, that substantial improvement in cure rates and median survival can be obtained utilizing dynamic precision medicine strategies. These dynamic strategies explicitly consider intratumoral heterogeneity and evolutionary dynamics, including predicted future drug resistance states, and reevaluate optimal therapy every 45 days. However, the optimization is performed in single 45 day steps ("single-step optimization"). Herein we evaluate analogous strategies that think multiple therapeutic maneuvers ahead, considering potential outcomes at 5 steps ahead ("multi-step optimization") or 40 steps ahead ("adaptive long term optimization (ALTO)") when recommending the optimal therapy in each 45 day block, in simulations involving both 2 and 3 non-cross resistant therapies. We also evaluate an ALTO approach for situations where simultaneous combination therapy is not feasible ("Adaptive long term optimization: serial monotherapy only (ALTO-SMO)"). Simulations utilize populations of 764,000 and 1,700,000 virtual patients for 2 and 3 drug cases, respectively. Each virtual patient represents a unique clinical presentation including sizes of major and minor tumor subclones, growth rates, evolution rates, and drug sensitivities. While multi-step optimization and ALTO provide no significant average survival benefit, cure rates are significantly increased by ALTO. Furthermore, in the subset of individual virtual patients demonstrating clinically significant difference in outcome between

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

    Cigarette smoking has long been implicated in cancer development and survival. However, few studies have investigated the impact of smoking on symptom burden in cancer survivors during treatment and at survivorship stage. This study examines the influence of cigarette smoking on side effects among 947 cancer patients during and 6 months following treatment. Patients diagnosed with cancer and scheduled to receive chemotherapy and/or radiation therapy reported on current smoking status (yes, no) and total symptom burden [the sum of 12 common symptoms (fatigue, hair loss, memory, nausea, depression, sleep, pain, concentration, hot flashes, weight loss, skin problems, and dyspnea) scored on an 11-point scale ranging from 0 = "not present" to 10 = "as bad as you can imagine"] during treatment and at 6-month follow-up. The adjusted mean total symptom burden by smoking status was determined by analysis of covariance controlling for age, gender, race, education, occupation, treatment, cancer site, and Karnofsky performance score. During treatment, smokers (S) had a significantly higher total symptom burden than nonsmokers (NS) (S = 46.3 vs. NS = 41.2; p < 0.05). At 6-month follow-up, smokers continued to report a higher total symptom burden than nonsmokers (S = 27.7 vs. NS = 21.9; p < 0.05). Participants who quit smoking before treatment levels had a total symptom burden similar to nonsmokers. Smoking was associated with an increased symptom burden during and following treatments for cancer. Targeted cessation efforts for smokers to decrease symptom burden may limit the likelihood of treatment interruptions and increase quality of life following treatment.

    Cancer treatment and treatment options are quite limited in circumstances such as when the tumor is inoperable, in brain cancers when the drugs cannot penetrate the blood-brain-barrier, or when there is no tumor-specific target for generation of effective therapeutic antibodies. Despite the fact that electromagnetic fields (EMF) in medicine have been used for therapeutic or diagnostic purposes, the use of non-ionizing EMF for cancer treatment is a new emerging concept. Here we summarize the history of EMF from the 1890's to the novel and new innovative methods that target and treat cancer by non-ionizing radiation.

    2017-02-01

    Lung cancer is one of the leading causes of cancer-related mortality worldwide. MicroRNAs (miRNAs) are endogenous non-coding small RNAs that repress the expression of a broad array of target genes. Many efforts have been made to therapeutically target miRNAs in cancer treatments using miRNA mimics and miRNA antagonists. Areas covered: This article summarizes the recent findings with the role of miRNAs in lung cancer, and discusses the potential and challenges of developing miRNA-targeted therapeutics in this dreadful disease. Expert opinion: The development of miRNA-targeted therapeutics has become an important anti-cancer strategy. Results from both preclinical and clinical trials of microRNA replacement therapy have shown some promise in cancer treatment. However, some obstacles, including drug delivery, specificity, off-target effect, toxicity mediation, immunological activation and dosage determination should be addressed. Several delivery strategies have been employed, including naked oligonucleotides, liposomes, aptamer-conjugates, nanoparticles and viral vectors. However, delivery remains a main challenge in miRNA-targeting therapeutics. Furthermore, immune-related serious adverse events are also a concern, which indicates the complexity of miRNA-based therapy in clinical settings.

    The aim of the study was to assess patients' awareness of the prevention and treatment of colorectal cancer. Patients diagnosed with colorectal cancer, hospitalised at the Department of General and Colorectal Surgery of the Medical University in Łódź during the period from January 2015 to April 2015, were asked to complete a questionnaire concerning their families' medical case record, factors predisposing them to the development of colorectal cancer, the tests applied in diagnostics, and the treatment process. The questionnaire comprised 42 closed-ended questions with one correct answer. A statistical analysis of all answers was carried out. The study group consisted of 30 men and 20 women aged 27-94 years old. A strong, statistically significant negative correlation between a patient's age and his/her awareness of the prevention and treatment of colorectal cancer was noted (pcancer (p=0.008), and the awareness of the prevention programme. The women's group was characterised by statistically significantly greater awareness of colonoscopy as a screening examination (p=0.004). Patients need more information on colorectal cancer, its risk factors, prevention, the treatment process, and postoperative care. Lack of awareness of the colorectal cancer issue can be one of the major factors contributing to the high incidence of this disease.

    Cancer creates a tremendous financial burden. Cancer-related costs are categorized into direct, indirect, and psychosocial costs. Although there have been many reports on medical care costs, which are direct, those on other costs are extremely scarce. We estimated travel time and costs required for cancer patients to receive outpatient treatment. We studied 521 cancer patients receiving anti-cancer treatment between February 2009 and December 2012 at the Outpatient Chemotherapy Center of Teikyo University Chiba Medical Center. Address data were extracted from Data Warehouse electronic medical records, and travel distance and time required for outpatient treatment were calculated via MapInfo and ACT Distance Calculator Package. Transportation costs were estimated on the basis of ¥274 (=$3.00) per kilometer. The study design was approved by an ethics review board of Teikyo University (12-851). Average round-trip travel distance, time, and cost for all patients were 26.7 km, 72.5 min, and ¥7,303 ($79.99), respectively. Cancer patients incurred a travel cost of ¥4000–¥9000 ($40.00 to $100.00) for each outpatient treatment. With population aging, seniors living alone and senior households are increasing, and outpatient visits are becoming a common burden

    Full Text Available For early-stage breast cancers mastectomy is an aggressive form of treatment. Therefore, there is a need for new treatment strategies that can enhance the use of lumpectomy by eliminating residual cancer cells with limited side effects to reduce local recurrence. Although, various radiotherapy-based methods have been developed, residual cells are found in 20-55% of the time at the first operation. Furthermore, some current treatment methods result in poor cosmesis. For the last decade, the authors have been exploring the use of polymeric composite materials in single and multi-modal implantable biomedical devices for post-operative treatment of breast cancer. In this paper, the concept and working principles of the devices, as well as selected results from experimental and numerical investigations, are presented. The results show the potential of the biomedical implants for cancer treatment.

    2018-01-01

    Full Text Available Background: The current legislation on the provision of medical assistance fixes the patient’s right to health care and medical assistance (Article 41 of the Constitution of the Russian Federation. Hence it follows that the patient has the opportunity to receive advice on the use of different treatment methods not only from his/her attending physician, but also from other doctors, to use available reference information, and to consider options for using methods of alternative medicine. Patients have the right to refuse treatment if they consider that the treatment options offered by the attending physician are inappropriate for them. Physicians have no right to treat patients without a patient’s informed consent. It is necessary to determine the actual legal model of the relationship between the attending physician and the patient, who may have different options for further treatment. The purpose of the study was to analyze the legislation on the protection of public health, which allows the attending physician to refuse further treatment of a patient, informing the chief physician about the reasons for the refusal.Results. In cases when cancer hospitals and centers refuse to treat patients who decline conventional cancer treatment and require alternative medicine instead, a signed mutual refusal of medical care is documented: the patient’s refusal of the treatment and the cancer institution’s refusal of the treatment options offered by the patient.

    Plants have been the primary source of medicines since life on earth; more than 50 % of existing cancer treatments are derived from plants. An ethnopharmacological survey of herbal remedies used in cancer treatment was carried out in the West Bank/ Palestine. A questionnaire was distributed to one hundred and fifty herbalists, traditional healers and rural dwellers. Collected information included the names of plants, the used parts, types of cancers for which these plants were used and also their methods of preparation. To identify the most important species used, Factor of informant's consensus (F(ic)), Fidelity level (Fl) and the Use-value (UV) were calculated. Collected data has shown that 72 plants are utilized for treatment of cancer, belonging to 44 families; from them Compositae and Lamiaceae were the most common. Leaves and fruits were the most commonly used parts, while decoctions, infusions and syrups were the main methods of preparation. Lung cancer was the most common type of cancer treated with these plants and Ephedra alata was the most commonly used plant for treatment of cancer in Palestine. The Fic was high for all the plants; Fl was 100% for many plants, the highest UV (0.72) was for Ephedra alata. This study showed that many herbal remedies are still used by herbalists in Palestine for treatment of cancer; some of them have been approved scientifically while others are not. A combined effort between informants and scientific institutions working in this field can help in the discovery of new anticancer agents. Moreover, scientists must explore the most suitable method of extraction, formulation and dose determination in order to achieve the best benefits from these herbals.

    2011-04-01

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

    A cost-utility study of a human papilloma virus (HPV) vaccine requires that the utility weights for HPV-related health states (i.e., cervical intraepithelial neoplasia (CIN), cervical cancer, and condyloma) be evaluated. The aim of the present study was to determine the utility weights for HPV-related health states. Hypothetical standardised health states related to HPV were developed based on patient education material and previous publications. To fully reflect disease progression from diagnosis to prognosis, each health state comprised four parts (diagnosis, symptoms, treatment, and progression and prognosis). Nine-hundred members from the Korean general population evaluated the HPV-related health states using a visual analogue scale (VAS) and a standard gamble (SG) approach, which were administered face-to-face via computer-assisted interview. The mean utility values were calculated for each HPV-related health state. According to the VAS, the highest utility (0.73) was HPV-positive status, followed by condyloma (0.66), and CIN grade I (0.61). The lowest utility (0.18) was cervical cancer requiring chemotherapy without surgery, followed by cervical cancer requiring chemoradiation therapy (0.42). SG revealed that the highest utility (0.83) was HPV-positive status, followed by condyloma (0.78), and CIN grade I (0.77). The lowest utility (0.43) was cervical cancer requiring chemotherapy without surgery, followed by cervical cancer requiring chemoradiation therapy (0.60). This study was based on a large sample derived from the general Korean population; therefore, the calculated utility weights might be useful for evaluating the economic benefit of cancer screening and HPV vaccination programs.

    The present study estimated the cost of advanced non-small cell lung cancer care for a cohort of 251 patients enrolled in a Brazilian public hospital and identified factors associated with the cost of treating the disease, considering sociodemographic, clinical and behavioral characteristics of patients, service utilization patterns and survival time. Estimates were obtained from the survey of direct medical cost per patient from the hospital's perspective. Data was collected from medical records and available hospital information systems. The ordinary least squares (OLS) method with logarithmic transformation of the dependent variable for the analysis of cost predictors was used to take into account the positive skewness of the costs distribution. The average cost of NSCLC was US$ 5647 for patients, with 71% of costs being associated to outpatient care. The main components of cost were daily hospital bed stay (22.6%), radiotherapy (15.5%) and chemotherapy (38.5%). The OLS model reported that, with 5% significance level, patients with higher levels of education, with better physical performance and less advanced disease have higher treatment costs. After controlling for the patient's survival time, only education and service utilization patterns were statistically significant. Individuals who were hospitalized or made use of radiotherapy or chemotherapy had higher costs. The use of these outpatient and hospital services explained most of the treatment cost variation, with a significant increase of the adjusted R 2 of 0.111 to 0.449 after incorporation of these variables in the model. The explanatory power of the complete model reached 62%. Inequities in disease treatment costs were observed, pointing to the need for strategies that reduce lower socioeconomic status and population's hurdles to accessing cancer care services.

    A prospective study was performed of patients diagnosed with colorectal cancer (CRC), distinguishing between colonic and rectal location, to determine the factors that may provoke a delay in the first treatment (DFT) provided. 2749 patients diagnosed with CRC were studied. The study population was recruited between June 2010 and December 2012. DFT is defined as time elapsed between diagnosis and first treatment exceeding 30 days. Excessive treatment delay was recorded in 65.5% of the cases, and was more prevalent among rectal cancer patients. Independent predictor variables of DFT in colon cancer patients were a low level of education, small tumour, ex-smoker, asymptomatic at diagnosis and following the application of screening. Among rectal cancer patients, the corresponding factors were primary school education and being asymptomatic. We conclude that treatment delay in CRC patients is affected not only by clinicopathological factors, but also by sociocultural ones. Greater attention should be paid by the healthcare provider to social groups with less formal education, in order to optimise treatment attention. PMID:27888636

    Although utility of three-dimensional (3D) helical CT for preoperative examination of breast cancer has been discussed, the accuracy of the helical CT in diagnosing breast cancer has not been fully evaluated. In this study 56 malignant and 28 benign breast tumors were evaluated preoperatively with 3D-helical CT, and their imaging results were compared with pathological findings of surgical specimens. Helical CT identified the presence of malignancy in 54 out of the 56 cancer cases tested and the sensitivity and specificity in distinguishing between malignant and benign tumors were 82% and 57%, respectively. The sensitivity and specificity in diagnosing the presence of metastatic axillary lymph nodes using helical CT were 70% and 80%, respectively. The sensitivity and specificity in diagnosing the presence of extensive intraductal component (EIC) using helical CT were 71% and 86%, respectively. Helical CT visualized all of the tumors in multifocal breast cancer cases. In conclusion, 3D-helical CT is a useful modality for preoperative examination of breast cancer, especially for assessing axillary lymph node status, and EIC, and will be helpful for conducting sentinel lymph node biopsy (SNLB) and breast-conserving surgery.

    Photodynamic therapy (PDT) is a new treatment utilizing the combined action of photosensitizers and light for the treatment of various cancers. The mechanisms for tumor destruction after PDT include direct tumor cell kill by singlet oxygen species (OS), indirect cell kill via vascular damage, and an elicited immune response. However, it has been reported that many cellular activators, including vascular endothelial growth factor (VEGF), are produced by tumor cells after PDT. In this study, we demonstrate that meta-tetra(hydroxyphenyl) chlorin (mTHPC)-based photodynamic therapy combined with bevacizumab (Avastin™), an anti-VEGF neutralizing monoclonal antibody that blocks the binding of VEGF to its receptor, can enhance the effectiveness of each treatment modality. We evaluated the efficacy of bevacizumab-based anti-angiogenesis in combination with PDT as well as the resulting VEGF levels in a mouse model of human colon cancer. Enzyme-linked immunosorbent assay (ELISA) and immunohistochemistry (IHC) were performed to assess VEGF concentrations in the various treatment groups, and confocal imaging and high performance liquid chromatography (HPLC) analyses were used to measure the distribution and concentration of mTHPC in tumors. Our results demonstrate that combination of PDT followed by bevacizumab significantly elicits a greater tumor response whereas bevacizumab treatment prior to PDT led to a reduced tumor response. Immunostaining and ELISA analyses revealed a lower expression of VEGF in tumors treated with combination therapy of PDT followed by bevacizumab. However, bevacizumab treatment decreased the accumulation of mTHPC in tumors 24 h after administration, which complemented the results of decreased anti-tumor efficacy of bevacizumab followed by PDT.

    Cachexia affects the majority of patients with advanced cancer and is associated with reduced treatment tolerance, response to therapy, quality of life, and life expectancy. Cachectic patients with advanced cancer often receive anti-cancer therapies against their specific cancer type as a standard of care, and whether specific ActRII inhibition is efficacious when combined with anti-cancer agents has not been elucidated yet. In this study, we evaluated interactions between ActRII blockade and anti-cancer agents in CT-26 mouse colon cancer-induced cachexia model. CDD866 (murinized version of bimagrumab) is a neutralizing antibody against the activin receptor type II (ActRII) preventing binding of ligands such as myostatin and activin A, which are involved in cancer cachexia. CDD866 was evaluated in association with cisplatin as a standard cytotoxic agent or with everolimus, a molecular-targeted agent against mammalian target of rapamycin (mTOR). In the early studies, the treatment effect on cachexia was investigated, and in the additional studies, the treatment effect on progression of cancer and the associated cachexia was evaluated using body weight loss or tumor volume as interruption criteria. Cisplatin accelerated body weight loss and tended to exacerbate skeletal muscle loss in cachectic animals, likely due to some toxicity of this anti-cancer agent. Administration of CDD866 alone or in combination with cisplatin protected from skeletal muscle weight loss compared to animals receiving only cisplatin, corroborating that ActRII inhibition remains fully efficacious under cisplatin treatment. In contrast, everolimus treatment alone significantly protected the tumor-bearing mice against skeletal muscle weight loss caused by CT-26 tumor. CDD866 not only remains efficacious in the presence of everolimus but also showed a non-significant trend for an additive effect on reversing skeletal muscle weight loss. Importantly, both combination therapies slowed down time

    Prostate cancer subjects with prostate-specific antigen (PSA) relapse who are treated with androgen deprivation therapy (ADT) are recommended to have baseline and serial bone densitometry and receive bisphosphonates. The purpose of this community population study was to assess the utilization of bone densitometry and bisphosphonate therapy in men receiving ADT for non-metastatic prostate cancer. A cohort study of men aged 65 years or older with non-metastatic incident diagnoses of prostate cancer was obtained from the Surveillance Epidemiology End Results (SEER)-linked Medicare claims between 2004 and 2008. Claims were used to assess prescribed treatment of ADT, bone densitometry, and bisphosphonates. A total of 30,846 incident prostate cancer cases receiving ADT and aged 65 years or older had no bone metastases; 87.3% (n=26,935) on ADT did not receive either bone densitometry or bisphosphonate therapy. Three percent (n=931) of the cases on ADT received bisphosphonate therapy without ever receiving bone densitometry, 8.8% (n=2,702) of the cases on ADT received bone densitometry without receiving intravenous bisphosphonates, while nearly 1% (0.90%, n=278) of the cases on ADT received both bone densitometry and bisphosphonates. Analysis showed treatment differed by patient characteristics. Contrary to the recommendations, bone densitometry and bisphosphonate therapy are underutilized in men receiving ADT for non-metastatic prostate cancer

    Incidence and mortality rates of cancer are currently on the top of disease pattern and the number is increasing and increasing worldwide. The impact of screening program for early diagnosis has been proved their important roles in the war against cancer because it helps increase the cure rates, decrease the mortality and morbidity rates, and therefore reduces the economic-social burden. Advances in diagnostic imaging techniques, especially the hybrid imaging (X-ray and Nuclear Medicine) such as PET/CT, SPECT/CT, PET/MRI, is important in accurate staging and these help choose the optimized treatment options to prolong survival while improve the quality of life. The treatment outcomes of cancer has certain remarkable advances based on variety of research to modify, promote and strengthen the traditional treatments (surgery-chemotherapy-radiation) such as laparoscopic surgery, combined chemo-regimens, intensity modulated radiation therapy, volumetric modulated arc therapy, stereotactic radiation therapy, radio surgery, PET/CT simulation, radioactive seeds implant, selective internal radiation therapy, intra-operative radiation therapy, etc. as well as the emerge of new methods such as targeted therapy, immune therapy, radio immunotherapy, proton therapy and heavy ion. Treatment of cancer is now the “individualized treatment” with the advances of biochemistry and histopathology. To achieve the most optimal outcomes, cancer should be approached by a multi professional team including biochemistry, immunology, histopathology, surgical oncology, medical oncology and radiation oncology.

    Full Text Available Steven P Weitzman, Maria E Cabanillas Department of Endocrine Neoplasia and Hormonal Disorders, The University of Texas MD Anderson Cancer Center, Houston, TX, USA Abstract: Although patients with thyroid cancer generally fare well, there is a subset for which this is not necessarily true. Progress in understanding the molecular aberrations in thyroid cancer has led to a change in the management of these cases. Since 2011, four multikinase inhibitors (MKIs have been approved by the US Food and Drug Administration for thyroid cancer – cabozantinib and vandetanib for medullary thyroid cancer and sorafenib and lenvatinib for differentiated thyroid cancer. This change in the treatment landscape has raised challenges for practitioners who may not be familiar with the use of MKIs or with the treatment and natural history of advanced thyroid cancer in general. This article reviews the epidemiology, molecular drivers, and initial treatment of patients with thyroid cancer and offers practical guidance to assist with the determination of when to appropriately start an MKI. As an example, cabozantinib and its efficacy are discussed in detail. Close monitoring is required for all patients on targeted agents to assess for adverse effects and response to therapy. An approach to managing drug-related adverse events is detailed. Since these drugs are not curative and have not yet proven to prolong overall survival, it is critical to weigh the risks and benefits of treatment at every visit. The potential value of changing to a different agent following failure of an MKI is also addressed. Keywords: chemotherapy, adverse event, targeted therapy, kinase inhibitor, VEGF, RET

    Second cancer risk in patients, in particular in children, who were treated with radiotherapy is an important side effect. It should be minimized by selecting an appropriate treatment plan for the patient. The objectives of this study were to integrate a risk model for radiation induced cancer into a treatment planning system which allows to judge different treatment plans with regard to second cancer induction and to quantify the potential reduction in predicted risk. A model for radiation induced cancer including fractionation effects which is valid for doses in the radiotherapy range was integrated into a treatment planning system. From the three-dimensional (3D) dose distribution the 3D-risk equivalent dose (RED) was calculated on an organ specific basis. In addition to RED further risk coefficients like OED (organ equivalent dose), EAR (excess absolute risk) and LAR (lifetime attributable risk) are computed. A risk model for radiation induced cancer was successfully integrated in a treatment planning system. Several risk coefficients can be viewed and used to obtain critical situations were a plan can be optimised. Risk-volume-histograms and organ specific risks were calculated for different treatment plans and were used in combination with NTCP estimates for plan evaluation. It is concluded that the integration of second cancer risk estimates in a commercial treatment planning system is feasible. It can be used in addition to NTCP modelling for optimising treatment plans which result in the lowest possible second cancer risk for a patient.

  6. Combined chemotherapy and radiotherapy in the treatment of lung cancer

    Wolf, M.

    1992-01-01

    In the past decade the prognosis of patients with locally advanced lung cancer has not been altered significantly. In both small and non-small cell lung cancer cure rates are poor and 5-year survival rate still has not exceeded the 5% borderline. Despite of initially high response rates, a vast majority of patients suffered from tumor progression within 2 years after the start of treatment. Sites of tumor progression are either the primary tumor or the occurrence of distant metastases. Therefore, improvements of both local and systemic tumor control are necessary to increase long-term survival rate in lung cancer. Combined chemo- and radiotherapy may be an appropriate treatment approach to reach these aims. In patients with locally advanced lung cancer combined chemo-radiotherapy aims at overcoming radio- and chemo-therapy resistance as a cause of local treatment failure and at early eradication of distant micrometastases as a cause of systemic treatment failure.

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

    During the last 10 years cancer in the Mexican pediatric population is growing. It is the second leading cause of death (children 1 to 14 years of age). The first step in controlling these diseases by registering the cases. Cancer Registry (CR) is fundamental for gaining knowledge that can be used for planning medical treatment and future research into causal factors and for the prevention. A CR is an information system designed to collect and encode data concerning individuals with cancer, and then to disseminate the compiled epidemiological results to various groups of stakeholders. Data are obtained from a hospital or group of hospitals, with special emphasis being placed on the quality of the data (completeness, validity and timeliness data). It is necessary a group of highly trained individuals called registrars, who are experts in the collection, encoding, and dissemination of internal reports to researchers and medical personnel. There are two main types of registries: those that are hospital based and those that are population based. The categories of data that should be collected are demographic data of the patient; descriptors of the cancer; details of the treatment administered; and details of the outcome of the treatment. It must be emphasized that all data conceming patients with cancer should be held in the strictest confidence.

    To investigate unmet information needs in newly diagnosed breast cancer patients over the course of cancer treatment and its association with health literacy. We present results from a prospective, multicenter cohort study (PIAT). Newly diagnosed breast cancer patients (N=1060) were surveyed directly after breast cancer surgery, 10 and 40 weeks later. Pooled linear regression modeling was employed analyzing changes in unmet information needs over time and its association with health literacy. Unmet information needs on side effects and medication and medical examination results and treatment options were high and increased during the first 10 weeks after breast cancer surgery. Considering health promotion and social issues, unmet information needs started high and decreased during post-treatment. Patients with limited health literacy had higher unmet information needs. Our results indicate a mismatch in information provision and breast cancer patients' information needs. Patients with limited health literacy may be at a distinct disadvantage in having their information needs met over the course of breast cancer treatment. Strategies are needed to reduce unmet information needs in breast cancer patients considering treatment-phase and health literacy and thereby enable them to better cope with their diseases.

    In this article the chance for a new tumour after a succesful treatment of breast cancer is worked out. The chance of a second tumour for treated women turns out to be three times as large as the change which an arbitrary group of contemporaries has of cancer. These (second) tumours mostly occur in the other breast. It is not quite clear in how far treatment with ionizing radiation can influence the origin of new tumours. The chance for re-occurring of breast cancer appears to be somewhat higher for women who underwent radiotherapy than for woman who were treated otherwise. Also leukemia occurred more often in women treated with than without ionnizing radiation; however, absolutely seen it does concern very small numbers. The importance of a good registration of cancer and the way of treatment of cancer are illustrated. Epidemiologic research as described may contribute in finding the most effective treatment with the least side effects. (H.W.). 15 refs.; 3 figs.; 3 tabs

    We aimed to (1) describe the utilization of mental health-care in survivors and siblings, the association with severity of distress, and visits to other professionals in distressed survivors not utilizing mental health-care; and (2) identify factors associated with utilization of mental health-care in distressed survivors. Within the Swiss Childhood Cancer Survivor Study, we sent postal questionnaires to all participants aged siblings could indicate if they utilized mental health-care in the past year. Psychological distress was assessed with the Brief Symptom Inventory-18 (BSI-18). Participants with scores T ≥ 57 on two of three scales or the Global Severity Index were considered distressed. We included 1,602 survivors and 703 siblings. Overall, 160 (10 %) and 53 (8 %), utilized mental health-care and 203 (14 %) and 127 (14 %) were considered distressed. Among these, 69 (34 %) survivors and 20 (24 %) siblings had utilized mental health-care. Participants with higher distress were more likely to utilize mental health-care. Distressed survivors not utilizing mental health-care were more likely to see a medical specialist than nondistressed. In the multivariable regression, factors associated with utilizing mental health-care were higher psychological distress and reporting late effects. Our results underline the importance of developing interventional programs and implementing psychological screening in follow-up of survivors. It is also important to systematically address siblings' needs. In follow-up, patients at risk should be informed about existing possibilities or advised to visit mental health professionals.

    Purpose: To utilize the National Cancer Data Base to evaluate trends in brachytherapy and alternative radiation therapy utilization in the treatment of cervical cancer, to identify associations with outcomes between the various radiation therapy modalities. Methods and Materials: Patients with International Federation of Gynecology and Obstetrics stage IIB-IVA cervical cancer in the National Cancer Data Base who received treatment from January 2004 to December 2011 were analyzed. Overall survival was estimated by the Kaplan-Meier method. Univariate and multivariable analyses were performed to identify factors associated with type of boost radiation modality used and its impact on survival. Results: A total of 7654 patients had information regarding boost modality. A predominant proportion of patients were Caucasian (76.2%), had stage IIIB (48.9%) disease with squamous (82.0%) histology, were treated at academic/research centers (47.7%) in the South (34.8%), and lived 0 to 5 miles (27.9%) from the treating facility. A majority received brachytherapy (90.3%). From 2004 to 2011, brachytherapy use decreased from 96.7% to 86.1%, whereas intensity modulated radiation therapy (IMRT) and stereotactic body radiation therapy (SBRT) use increased from 3.3% to 13.9% in the same period (P<.01). Factors associated with decreased brachytherapy utilization included older age, stage IVA disease, smaller tumor size, later year of diagnosis, lower-volume treatment centers, and facility type. After controlling for significant factors from survival analyses, IMRT or SBRT boost resulted in inferior overall survival (hazard ratio, 1.86; 95% confidence interval, 1.35-2.55; P<.01) as compared with brachytherapy. In fact, the survival detriment associated with IMRT or SBRT boost was stronger than that associated with excluding chemotherapy (hazard ratio, 1.61′ 95% confidence interval, 1.27-2.04′ P<.01). Conclusions: Consolidation brachytherapy is a critical treatment component for

    Men diagnosed with localized prostate cancer face a potentially life-altering treatment decision that can be overwhelming. Enhancing patient knowledge through education can significantly reduce feelings of uncertainty while simultaneously increasing confidence in decision making. Serious games have been shown in other populations to increase health knowledge and assist with the health decision-making process. We developed an interactive serious game, Time After Time, which translates evidence-based treatment outcome data into an accessible and understandable format that men can utilize in their prostate cancer treatment decision-making process. The game specifically aims to raise men's awareness and understanding of the impact of health-related quality of life issues associated with the major treatment options and to enrich their conversations with their health care providers. This study determined the acceptability and usability of the alpha version of Time After Time, an interactive decision aid for men diagnosed with localized prostate cancer, in order to inform future iterations of the serious game. The study employed a mixed methods approach to assess the acceptability and usability of the Time After Time serious game using qualitative focus groups and a quantitative Likert scale survey. A total of 13 men who had already completed treatment for localized prostate cancer completed the survey and participated in focus group meetings. The majority of the study participants rated Time After Time as an appropriate decision tool for localized prostate cancer and verified that it meets its goals of increasing focus on side effects and generating questions for the patient's health care team. However, participants also expressed concerns about game usability and the diversity of information covered regarding treatment options and potential treatment outcomes. Serious games are a promising approach to health education and decision support for older men. Participants

  20. Analytical signals from cancer patients following radiation treatment

    Cancer patients are treated with high energy (8 to 30 MeV) gamma radiation. This treatment modality provides better depth dose distribution than more conventional low-energy gamma treatments, in particular for deeply located tumors. A by-product of the high-energy treatment is gamma-induced activity in the treatment volume following photonuclear reactions. These reactions are endogenic and require that the gamma radiation energy be above threshold value in order for the reaction to take place. For most elements, the threshold value is above 8 MeV; however, for low Z elements, this threshold may reach 18 MeV as is the case for oxygen. The cross sections for the (γ, n) reactions are few millibarns for low Z elements and increases up to few hundreds of millibarns for the heavy elements. The radionuclides resulting from photonuclear reaction are typically positron emitter or decay by electron capture. Thus, it is possible to monitor either the annihilation radiation (511 KeV) or the characteristic gamma radiation. The present work demonstrates that the activity induced in cancer patients following a single treatment (300 rad) enables the monitoring of nitrogen and phosphorus in the irradiated volume. The results from measurements in phantom, cadavers, and cancer patients from different regions in the body are presented. The hypothesis to be tested is whether there are local changes in these two elements during the course of radiation treatment which might correlate with the efficacy of the treatment

    Our objective is to compare the cost-utility of icotinib and gefitinib for the second-line treatment of advanced non-small cell lung cancer (NSCLC) from the perspective of the Chinese healthcare system. Model technology was applied to assess the data of randomized clinical trials and the direct medical costs from the perspective of the Chinese healthcare system. Five-year quality-adjusted life years (QALYs) and incremental cost-utility ratios (ICURs) were calculated. One-way and probabilistic sensitivity analyses (PSA) were performed. Our model suggested that the median progression-free survival (PFS) was 4.2 months in the icotinib group and 3.5 months in the gefitinib group while they were 4.6 months and 3.4 months, respectively, in the trials. The 5-year QALYs was 0.279 in the icotinib group and 0.269 in the gefitinib group, and the according medical costs were $10662.82 and $13127.57. The ICUR/QALY of icotinib versus gefitinib presented negative in this study. The most sensitive parameter to the ICUR was utility of PFS, ranging from $-1,259,991.25 to $-182,296.61; accordingly the icotinib treatment consistently represented a dominant cost-utility strategy. The icotinib strategy, as a second-line therapy for advanced NSCLC patients in China, is the preferred strategy relative to gefitinib because of the dominant cost-utility. In addition, icotinib shows a good curative effect and safety, resulting in a strong demand for the Chinese market.

    Cancer is a leading cause of mortality worldwide. Early diagnosis and treatment of cancer may curb the growing burden of the disease. Understanding cancer patients' navigation pathways for seeking treatment is important in order to facilitate early diagnosis and treatment. With this background we conducted a hospital-based cross-sectional study comprising 68 randomly selected cancer inpatients in a tertiary cancer specialty hospital in Odisha, India, to explore the treatment-seeking pathways of the cancer patients and the barriers and enablers in seeking treatment. Financial constraint is one of the major reasons for the delay in accessing treatment, even when patients are suspected of or diagnosed with cancer. Low awareness of the presenting signs and symptoms of cancer and limited knowledge of the availability of cancer diagnosis and treatment facilities are major factors contributing to delay. Family and friends' support is found to be the major enabling factor toward seeking treatment. Generation of awareness of cancer among the general population and primary-care practitioners - including those in alternative systems of medicine - is important. Information on diagnostic and treatment services appears to be a felt need. Copyright © 2013 Elsevier Ltd. All rights reserved.

    2013-01-01

    Objectives Oropharyngeal cancer (OPC) is the 6th most common cancer worldwide. Focus on risk factors, improved diagnostic methods and effective management strategies have made it possible to successfully treat OPC. However, the 5-year survival rate has not improved for several years due to multiple treatment complications, tissue morbidity, loss of function and diminished quality of life. Survivors are faced with complications like oral mucositis, hyposalivation, osteoradionecrosis; tissue fibrosis, morbidity from jaw resection; disfigurement and loss of function that further diminish quality of life. The aim of this review is to highlight major complications associated with treatment of OPC via a literature search and review of available options for identification and management of these complications. Data Sources Relevant publications on oral complications of OPC therapy were thoroughly reviewed from the literature published between the years 1988 and 2012. Material and Method We evaluated reported incidence, prevalence and risk factors for oral complications of chemotherapy and radiotherapy for OPC. The authors conducted electronic search using English language databases namely PubMed Plus, Medline (Pre-Medline and Medline), Cochrane Database of systematic reviews (evidence-based medicine), Dentistry & Oral sciences source, AccessScience, Embase, Evidence-Based Medicine Reviews Multifile, Google Scholar, ISI Journal Citation Reports, Ovid Multi-Database. Conclusion We identified the most common complications associated with the treatment of oral cancers. Based on the information gathered, there is evidence that survival of OPC extends beyond eradication of the diseased tissue. Understanding the potential treatment complications and utilizing available resources to prevent and minimize them are important. Caring for OPC survivors should be a multidisciplinary team approach involving the dentist, oncologist, internist and social worker to improve the currently

    2012-01-01

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

    Somatization and hypochondriacal health anxiety are common sources of distress, impairment, and costly medical utilization in primary care practice. A range of interventions is needed to improve the care of these patients. To determine the effectiveness of two cognitive behavioral interventions for high-utilizing, somatizing patients, using the resources found in a routine care setting. Patients were randomly assigned to a two-step cognitive behavioral treatment program accompanied by a training seminar for their primary care physicians, or to relaxation training. Providers routinely working in these patients' primary care practices delivered the cognitive behavior therapy and relaxation training. A follow-up assessment was completed immediately prior to treatment and 6 and 12 months later. Eighty-nine medical outpatients with elevated levels of somatization, hypochondriacal health anxiety, and medical care utilization. Somatization and hypochondriasis, overall psychiatric distress, and role impairment were assessed with well-validated, self-report questionnaires. Outpatient visits and medical care costs before and after the intervention were obtained from the encounter claims database. At 6 month and 12 month follow-up, both intervention groups showed significant improvements in somatization (p somatization, hypochondriacal symptoms, overall psychiatric distress, and role function. They also reduced the ambulatory visits and costs of these high utilizing outpatients.

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

    Purpose: To determine the effect of prostate cancer therapy (surgery or external beam irradiation, or both or none) on the actuarial incidence of subsequent bladder cancer. Methods and Materials: The Surveillance, Epidemiology, and End Results registry from 1973 to 2005 was analyzed. Treatment was stratified as radiotherapy, surgery, both surgery and adjuvant radiation, and neither modality. Brachytherapy was excluded. Results: In all, 555,337 prostate carcinoma patients were identified; 124,141 patients were irradiated; 235,341 patients were treated surgically; 32,744 patients had both surgery and radiation; and 163,111 patients received neither modality. Bladder cancers were diagnosed in: 1,836 (1.48%) men who were irradiated (mean age, 69.4 years), 2,753 (1.09%) men who were treated surgically (mean age, 66.9 years); 683 (2.09%) men who received both modalities (mean age, 67.4 years), and 1,603 (0.98%) men who were treated with neither modality (mean age, 71.8 years). In each treatment cohort, Kaplan-Meier analyses showed that increasing age (by decade) was a significant predictor of developing bladder cancer (p < 0.0001). Incidence of bladder cancer was significantly different for either radiation or surgery alone versus no treatment, radiation versus surgery alone, and both surgery and radiation versus either modality alone (p < 0.0001). On multivariate analysis, age and irradiation were highly significant predictors of being diagnosed with bladder cancer. Conclusions: Following prostate cancer, increasing age and irradiation were highly significant predictors of being diagnosed with bladder cancer. While use of radiation increased the risk of bladder cancer compared to surgery alone or no treatment, the overall incidence of subsequent bladder cancer remained low. Routine bladder cancer surveillance is not warranted.

    Full Text Available Circulating cell-free DNA (cfDNA isolated from the plasma of cancer patients (pts has been shown to reflect the genomic mutation profile of the tumor. However, physician and patient assessment of clinical utility of these assays in patients with metastatic colorectal cancer (mCRC has not been previously described.Patients were prospectively consented to a prospective genomic matching protocol (Assessment of Targeted Therapies Against Colorectal Cancer [ATTACC], with collection of blood for cfDNA extraction and sequencing of a 54-gene panel in a CLIA-certified lab. Formalin-fixed, paraffin-embedded (FFPE tissue from prior resections or biopsies underwent 50-gene sequencing. Results from both assays were returned to the treating physicians for patient care and clinical trial selection. Follow-up surveys of treating physicians and chart reviews assessed clinical utility.128 mCRC pts were enrolled between 6/2014 and 1/2015. Results were returned in median of 13 and 26 days for cfDNA and FFPE sequencing, respectively. With cfDNA sequencing, 78% (100/128 of samples had a detectable somatic genomic alteration. 50% of cfDNA cases had potentially actionable alterations, and 60% of these could be genomically matched to at least one clinical trial in our institution. 50% (15/30 of these pts enrolled onto an identified matched trial. Physicians reported that the cfDNA testing improved the quality of care they could provide in 73% of the cases, and that 89% of pts reported greater satisfaction with the efforts to personalize experimental therapeutic agents.cfDNA sequencing can provide timely information on potentially actionable mutations and amplifications, thereby facilitating clinical trial enrollment and improving the perceived quality of care.

    2009-01-01

    Background. There is wide variation in prostate cancer incidence and survival across Europe. In many countries incidence is rising sharply in relation to the introduction of prostate-specific antigen assay, and there is concern that patients may not be treated appropriately. We therefore aimed to characterize treatment for prostate cancer across Europe. Methods. We performed a high resolution population-based study, collecting information on the treatment of 3 486 prostate cancer cases diagnosed in 1995-1999 in 11 cancer registries from six European countries. Results. Overall, about one in three patients received radical treatment (prostatectomy 23% or radiotherapy 14%); about 60% of younger patients ( 70% in Civilised, Haut-Rh in, Tarn and Eindhoven and <50% in Slovakia and Cracow. Overall 34% of patients with apparently low-risk disease received radical treatment, varying from 17% and 22% in Bas-Rhin and Granada, to 52% and 56% in Calvados and Eindhoven. Conclusions. Our data indicate wide variation in the treatment for prostate cancer even among patients with apparently similar disease, and further suggest a non-negligible proportion may be receiving inappropriate radical treatment for apparently low-risk disease. Current guidelines indicate active surveillance should become the main means of managing low-risk disease

    Women who are diagnosed with breast cancer have many decisions to make during the course of their treatment. The aims of this paper are to describe the women's experience of making radiation therapy treatment decisions for early breast cancer and to explore how women feel about receiving radiation therapy. An in-depth understanding of the women's experience was developed using a qualitative research approach underpinned by hermeneutic phenomenology. In-depth interviews were conducted with 18 women who had completed treatment for early breast cancer. The themes that emerged from the data were: being challenged, getting ready, beyond control, regaining a sense of control and getting through it. This study provides health professionals with an initial understanding of the women's perspective of the experience of making radiation therapy treatment decisions for early breast cancer. This study concludes by suggesting that further research needs to be conducted to gain an understanding of how other patients feel about treatment decision making and radiation therapy.

    Approximately 50% of high-grade serous ovarian cancers present a deficiency in the pathways involved in homologous recombination (HR). PARP inhibitors prevent single-strand DNA damage repair and determine a progression of the defect towards double-strand breaks, which results in a process known as 'synthetic lethality'. Areas covered: In this review, the authors discuss the efficacy and toxicity of rucaparib either as a single agent or as a maintenance treatment for ovarian cancer. This includes the NGS Foundation Medicine evaluation of the role of this drug in the treatment algorithm of ovarian cancer. Moreover, perspectives on the future development of this drug are presented. Expert opinion: The FDA has approved this drug for the treatment of recurrent BRCA-mutated ovarian cancers, which were previously treated with at least two chemotherapies and has accepted the supplemental new drug application for maintenance use in patients who respond to platinum-based chemotherapy via the Prescription Drug User Fee Act (PDUFA) on 6 April 2018. European Medicines Agency (EMA) approval in the same setting is awaited. The possibility of using PARP inhibitors as a maintenance therapy, as a front-line therapy to combat recurrence, and in combination with anti-angiogenic agents and immune-therapies appears to be of particular interest.

    Gynecomastia, defined as benign proliferation of glandular breast tissue has a prevalence of 32% to 72% in the male. In the urology setting, it is associated to patients with prostate cancer and hormone treatment with a prevalence of 15% in the case of complete hormone blockage and 75% in monotherapy. The different options of treatment in prostate cancer have changed in recent decades. Thus, we have focused on this subject to evaluate the different therapy options of hormone manipulation induced gynecomastia in prostate cancer patients. To synthesize the available evidence on the different therapeutic options in prostate cancer patients who develop gynecomastia due to the use of nonsteroidal antiandrogens and to generate a diagnostic algorithm and treatment. Using the PICO type structured search strategy (Patient or problem, Intervention, Comparison, Outcome or result) in the data bases of PubMed-Medline and Cochrane, identification was made of the relevant studies related to the treatment of gynecomastia in Prostate Cancer patients treated with nonsteroidal antiandrogens. We have found 3 possible therapeutic options for the treatment of gynecomastia and mastodynia in patients with hormone deprivation therapy for prostate cancer. The 10Gy radiotherapy would be an option for the treatment of gynecomastia, although not all the patients need prophylactic treatment since only 50% report moderate-severe discomfort. Another option is the use of drugs such as tamoxifen 20mg/day that lead to a significant decrease in the mammary effects. Gynecomastia and mastodynia, given their high incidence, make the physical examination a fundamental tool for all patients before initiating treatment with antiandrogens. The use of tamoxifen 20mg/day is the best treatment and prevention option against gynecomastia and mastodynia, while in the case of long-course established gynecomastia, surgery is the gold standard.

    Combined modality chemoirradiation is commonly used as a component of treatment in combination with maximum resection for both high-risk resectable and locally advanced primary or recurrent rectal cancers. With surgically resected but high-risk rectal cancers, postoperative chemoirradiation has been shown to improve both disease control (local and distant) and survival (disease-free and overall) and was recommended as standard adjuvant treatment at the 1990 National Institute of Health (NIH) Consensus Conference on Adjuvant treatment for patients with rectal and colon cancers. Subsequent intergroup trials are being conducted to help define optimal combinations of postoperative chemoirradiation for resected high-risk rectal cancers and to test sequencing issues of preoperative versus postoperative chemoirradiation. With locally unresectable primary or recurrent colorectal cancers, standard therapy with surgery, external beam irradiation (EBRT) and chemotherapy is often unsuccessful. When intraoperative electron irradiation (IOERT) is combined with standard treatment, local control and survival appear to be improved in separate analyses from the Mayo Clinic and the Massachusetts General Hospital (MGH). However, routine use of systemic therapy is also needed as a component of treatment, in view of high rates of systemic failure. (orig.)

With surgically resected but high-risk rectal cancers, postoperative chemoirradiation has been shown to improve both disease control (local and distant) and survival (disease-free and overall) and was recommended as standard adjuvant treatment at the 1990 National Institute of Health (NIH) Consensus Conference on Adjuvant treatment for patients with rectal and colon cancers. Subsequent intergroup trials are being conducted to help define optimal combinations of postoperative chemoirradiation for resected high-risk rectal cancers and to test sequencing issues of preoperative versus postoperative chemoirradiation. With locally unresectable primary or recurrent colorectal cancers, standard therapy with surgery, external beam irradiation (EBRT) and chemotherapy is often unsuccessful. When intraoperative electron irradiation (IOERT) is combined with standard treatment, local control and survival appear to be improved in separate analyses from the Mayo Clinic and the Massachusetts General Hospital (MGH). However, routine use of systemic therapy is also needed as a component of treatment, in view of high rates of systemic failure. (orig.)

    Full Text Available As the leading cause of morbidity and cancer related-death worldwide, lung cancer has a serious threat to human health. Exosomes are nanoscale lipid membrane vesicles derived from multivesicles, which containing active biomolecules including proteins, lipids, nucleic acids and etc. Exosomes play important roles in lung cancer initiation and progression by promoting the formation of tumor microenvironment, enhancing tumor invasive and metastasis capability, leading to immunosuppression and resistance to chemoradiotherapy, and also have the application value in early diagnosis and treatment. This review summarizes the research progress of exosomes in tumor initiation and progression, and its roles in diagnosis and treatment of lung cancer.

    Advances in surgical techniques, in chemotherapy, and in radiation therapy have led to improved survival in children treated for cancer. Children cured of cancer will soon form a significant fraction of our adult population. As we follow such survivors, we have become more aware of long-term side effects of treatment. This is not a reason to withhold therapy. Instead, careful followup of oncology patients is needed to document the late effects, to identify the etiologic agents, and to alter treatment to give the least toxic therapy without sacrificing quality or duration of survival

    , 10 236 women with primary breast cancer aged 45 years or less at the time of diagnosis were followed for 95 616 person years. Among these, 371 women experienced pregnancy after treatment of breast cancer. In a multivariate analysis that included age at diagnosis, stage of disease, and pregnancy...... history prior to diagnosis, women who had a full-term pregnancy subsequent to breast cancer treatment were found to have a reduced risk of dying (relative risk: 0.73; 95% confidence interval: 0.54-0.99) compared with other women with breast cancer. The effect was not significantly modified by age...... at diagnosis, tumour size, nodal status, or pregnancy history before diagnosis of breast cancer. Neither spontaneous abortions nor induced abortions subsequent to breast cancer treatment had a negative impact on prognosis. CONCLUSION: In line with our previous study, but based on more than twice the patient...

    The objective of this paper was to assess the cost-utility of fidaxomicin versus vancomycin in the treatment of Clostridium difficile infection (CDI) in three specific CDI patient subgroups: those with cancer, treated with concomitant antibiotic therapy or with renal impairment. A Markov model with six health states was developed to assess the cost-utility of fidaxomicin versus vancomycin in the patient subgroups over a period of 1 year from initial infection. Cost and outcome data used to parameterise the model were taken from Spanish sources and published literature. The costs were from the Spanish hospital perspective, in Euros (€) and for 2013. For CDI patients with cancer, fidaxomicin was dominant versus vancomycin [gain of 0.016 quality-adjusted life-years (QALYs) and savings of €2,397 per patient]. At a cost-effectiveness threshold of €30,000 per QALY gained, the probability that fidaxomicin was cost-effective was 96 %. For CDI patients treated with concomitant antibiotic therapy, fidaxomicin was the dominant treatment versus vancomycin (gain of 0.014 QALYs and savings of €1,452 per patient), with a probability that fidaxomicin was cost-effective of 94 %. For CDI patients with renal impairment, fidaxomicin was also dominant versus vancomycin (gain of 0.013 QALYs and savings of €1,432 per patient), with a probability that fidaxomicin was cost-effective of 96 %. Over a 1-year time horizon, when fidaxomicin is compared to vancomycin in CDI patients with cancer, treated with concomitant antibiotic therapy or with renal impairment, the use of fidaxomicin would be expected to result in increased QALYs for patients and reduced overall costs.

    To prevent postoperative local recurrence of rectal cancer, we treated patients using preoperative hyperthermia (5-6 times), irradiation (total 30 Gy) and 5-fluorouracil suppository (2,000-2,500 mg). The subjects were 31 patients given combined treatments and 28 patients given surgery alone. The results were as follows: Histologically, therapeutic effects were recognized in 80.6% of patients receiving combined treatments. The mean distance from the adventitia to the site of cancer infiltration was 6.54 mm in the combined treatments group and 3.35 mm in the surgery alone group. The difference between the two was significant (p<0.05). The rate of local recurrence in the combined treatments group was less than that in the surgery alone group. No systemic side effects nor severe complications were observed during hospitalization in the combined treatments group. The survival rate of the combined treatments group was higher than that of the surgery alone group. It was considered that combined preoperative treatments for rectal cancer were beneficial to survival and local control. (author)

    Full Text Available Providing access to and utilization of medication assisted treatment (MAT for the treatment of opioid abuse and dependence provides an important opportunity to improve public health. Access to health services comprising MAT in the community is fundamental to achieve broad service coverage. The type and placement of the health services comprising MAT and integration with primary medical care including human immunodeficiency virus (HIV prevention, care and treatment services are optimal for addressing both substance abuse and co-occurring infectious diseases. As an HIV prevention intervention, integrated (same medical record for HIV services and MAT services MAT with HIV prevention, care and treatment programs provides the best “one stop shopping” approach for health service utilization. Alternatively, MAT, medical and HIV services can be separately managed but co-located to allow convenient utilization of primary care, MAT and HIV services. A third approach is coordinated care and treatment, where primary care, MAT and HIV services are provided at distinct locations and case managers, peer facilitators, or others promote direct service utilization at the various locations. Developing a continuum of care for patients with opioid dependence throughout the stages MAT enhances the public health and Recovery from opioid dependence. As a stigmatized and medical disenfranchised population with multiple medical, psychological and social needs, people who inject drugs and are opioid dependent have difficulty accessing services and navigating medical systems of coordinated care. MAT programs that offer comprehensive services and medical care options can best contribute to improving the health of these individuals thereby enhancing the health of the community.

    Different approaches for treating lung cancer have been developed over time, including chemotherapy, radiotherapy and targeted therapies against activating mutations. Lately, better understanding of the role of the immunological system in tumor control has opened multiple doors to implement different strategies to enhance immune response against cancer cells. It is known that tumor cells elude immune response by several mechanisms. The development of monoclonal antibodies against the checkpoint inhibitor programmed cell death protein 1 (PD-1) and its ligand (PD-L1), on T cells, has led to high activity in cancer patients with long lasting responses. Nivolumab, an anti PD-1 inhibitor, has been recently approved for the treatment of squamous cell lung cancer patients, given the survival advantage demonstrated in a phase III trial. Pembrolizumab, another anti PD-1 antibody, has received FDA breakthrough therapy designation for treatment of non-small cell lung cancer (NSCLC), supported by data from a phase I trial. Clinical trials with anti PD-1/PD-L1 antibodies in NSCLC have demonstrated very good tolerability and activity, with response rates around 20% and a median duration of response of 18 months

    This paper summarizes the treatment of locally advanced breast cancer, inflammatory breast cancer, and locally recurrent breast cancer. A multidisciplinary approach considering subclinical distant metastases is needed to treat these types of breast cancer. Subclinical distant metastasis is observed in about 80% of case of locally advanced cancer, and treatment of subclinical distant metastases, e.g., by endocrinotherapy and chemotherapy, is therefore essential to improving the prognosis. The standard therapy for unresectable locally advanced breast cancer consists of induction chemotherapy with anthracyclines and local treatment with mastectomy or irradiation. Previous reports have stated that induction chemotherapy was effective in 60-80% of the primary lesions or lymph node metastasis, and the CR rates were in the 10-20% range. Combination therapy with induction chemotherapy clearly improved the outcome over local treatment alone. The usual irradiation dose is 50 to 60 Gy/5 to 7 weeks to the whole breast or the thoracic wall. Boost irradiation at a dose of 10 to 25 Gy is performed in unresectable cases. The boost irradiation dose to the lymph node area is usually 45 to 50 Gy/5 to 6 weeks in cases without gross lesions and 10 to 15 Gy in cases with gross lesions. Combination therapy consisting of conservative pectoral mastectomy and postoperative adjuvant chemo- endocrino-therapy (i.e., adjuvant therapy) has become the standard regimen for treating resectable locally advanced breast cancer, because it significantly improves the recurrence rate and survival rate compared to local treatment alone. Some clinical have studies indicated that neoadjuvant therapy (i.e., induction chemotherapy + surgery/radiation therapy) is comparable or superior to adjuvant therapy in terms of improving the prognosis. However, the efficacy and most appropriate method of breast-conserving therapy after induction chemotherapy are still unclear. More clinical trials are needed. It has been

    There is often a considerable lapse of time between the definition of what causes a disease in the laboratory and the development of successful therapy. However, the history of medicine teaches us that the need to understand the scientific basis of disease before the discovery of new treatments is both essential and inevitable. During the middle of the 19th century, the work of the great German pathologist, Rudolf Virchow, defined disease as having an anatomic or histologic basis. In the clinic, this scientific perspective would lead to increasingly effective and, often, increasingly aggressive surgical approaches to disease. Later in the 19th century, Koch's discovery of the tubercle bacillus (a discovery Virchow disbelieved and publication of which he thwarted, since he hypothesized that cancer, not microbes, caused consumption!), would define a microbiological basis for disease. With bacteria defined as a major cause of human suffering, the stage was set for the development of the discovery of effective antibiotics. In the early 20th century, the pioneering work of Banting, Best and others would show that disease can also have an endocrine or metabolic basis. This new body of scientific knowledge would lead not only to the specific discovery of insulin as an effective treatment for diabetes but also to a more general understanding of the role of hormones, vitamins and co-factors in human health and disease. Basic medical research and its successful translation into effective treatments has fundamentally altered the cause of human death. In the developed world, where access to the benefit of this work is available, infectious disease is not the problem it was in the days of Pasteur, Metchnikoff and Ehrlich. As we approach the millennium, science is now teaching us that diseases, particularly cancer, can have a molecular or genetic basis. Can successful application of this new knowledge be far behind? We are already seeing the application of this new knowledge in

    Full Text Available Abstract Background Chronic medical diseases require regular and longitudinal care and self-management for effective treatment. When chronic diseases include substance use disorders, care and treatment of both the medical and addiction disorders may affect access to care and the ability to focus on both conditions. The objective of this paper is to evaluate the association between the presence of chronic medical disease and recent addiction treatment utilization among adults with substance dependence. Methods Cross-sectional secondary data analysis of self-reported baseline data from alcohol and/or drug-dependent adults enrolled in a randomized clinical trial of a disease management program for substance dependence in primary care. The main independent variable was chronic medical disease status, categorized using the Katz Comorbidity Score as none, single condition of lower severity, or higher severity (multiple conditions or single higher severity condition, based on comorbidity scores determined from self-report. Asthma was also examined in secondary analyses. The primary outcome was any self-reported addiction treatment utilization (excluding detoxification in the 3 months prior to study entry, including receipt of any addiction-focused counseling or addiction medication from any healthcare provider. Logistic regression models were adjusted for sociodemographics, type of substance dependence, recruitment site, current smoking, and recent anxiety severity. Results Of 563 subjects, 184 (33% reported any chronic disease (20% low severity; 13% higher severity and 111 (20% reported asthma; 157 (28% reported any addiction treatment utilization in the past 3 months. In multivariate regression analyses, no significant effect was detected for chronic disease on addiction treatment utilization (adjusted odds ratio [AOR] 0.88 lower severity vs. none, 95% confidence interval (CI: 0.60, 1.28; AOR 1.29 higher severity vs. none, 95% CI: 0.89, 1.88 nor for

    A new problem has emerged with the ever-increasing number of breast cancer survivors. While early screening and advances in treatment have allowed these patients to overcome their cancer, these treatments often have adverse cardiovascular side effects that can produce abnormal cardiovascular function. Chemotherapeutic and radiation therapy have both been linked to cardiotoxicity; these therapeutics can cause a loss of cardiac muscle and deterioration of vascular structure that can eventually ...

    External beam radiation therapy with concurrent chemotherapy (CRT) is widely used for the treatment of unresectable pancreatic cancer. Noncoplanar (NCP) 3D conformal radiotherapy (3DCRT) and coplanar (CP) IMRT have been reported to lower the radiation dose to organs at risk (OARs). The purpose of this article is to examine the utility of noncoplanar beam angles in IMRT for the management of pancreatic cancer. Sixteen patients who were treated with CRT for unresectable adenocarcinoma of the pancreatic head or neck were re-planned using CP and NCP beams in 3DCRT and IMRT with the Varian Eclipse treatment planning system. Compared to CP IMRT, NCP IMRT had similar target coverage with slightly increased maximum point dose, 5,799 versus 5,775 cGy (p = 0.008). NCP IMRT resulted in lower mean kidney dose, 787 versus 1,210 cGy (p kidney dose, but did not improve other dose-volume criteria. The use of NCP beam angles is preferred only in patients with risk factors for treatment-related kidney dysfunction.

    The Canadian province of Manitoba covers a large geographical area but only has one major urban center, Winnipeg. We sought to determine if regional differences existed in the quality of colorectal cancer care in a publicly funded health care system. This was a population-based historical cohort analysis of the treatment and outcomes of Manitobans diagnosed with colorectal cancer between 2004 and 2006. Administrative databases were utilized to assess quality of care using published quality indicators. A total of 2,086 patients were diagnosed with stage I to IV colorectal cancer and 42.2% lived outside of Winnipeg. Patients from North Manitoba had a lower odds of undergoing major surgery after controlling for other confounders (odds ratio (OR): 0.48, 95% confidence interval (CI): 0.26 to 0.90). No geographic differences existed in the quality measures of 30-day operative mortality, consultations with oncologists, surveillance colonoscopy, and 5-year survival. However, there was a trend towards lower survival in North Manitoba. We found minimal differences by geography. However, overall compliance with quality measures is low and there are concerning trends in North Manitoba. This study is one of the few to evaluate population-based benchmarks for colorectal cancer therapy in Canada.
