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

Part 1 of this two-part article provides an overview of bladder cancer and discusses its management. Since publication of a previous article entitled 'Understanding the role of smoking in the aetiology of bladder cancer' ( Anderson, 2009 ), the author has received many requests for an update. This article provides an overview of bladder cancer and its current management practices, underlining the continued role of smoking as the predominant risk factor in the disease's development. The management of bladder cancer is governed by specific guidelines. Management of non-muscle-invasive cancers, including surgical intervention with transurethral resection, and intravesical therapy using chemotherapy and immunotherapy agents, is discussed. Cystectomy (removal of the bladder), is sometimes necessary. Treatments are effective in reducing tumour recurrence, but the effects of the risks and side-effects on the individual's quality of life can be significant. The prevalence of bladder cancer, and the nature of its management make this cancer one of the most expensive for the NHS to treat. The effectiveness of health promotional strategies in increasing peoples' awareness of their risk of developing the disease, and in enabling them to change long-term health behaviours is discussed. The role of the multidisciplinary team is explored, along with that of the uro-oncology cancer nurse specialist. Part 2 will consider the management of muscle-invasive and metastatic bladder cancer.

Colon cancer and diverticular disease are most common in the Western world and their incidences tend to increase with advancing age. The association between the diseases remains unclear. To analyse the risk of colon cancer after hospitalisation for diverticular disease. Nationwide case-control study. A total of 41,037 patients with colon cancer during 1992-2006, identified from the Swedish Cancer Register were included. Each case was matched with two control subjects. From the Swedish Inpatient Register, cases and control subjects hospitalised for diverticular disease were identified. Odds ratios (OR) and confidence intervals for receiving a diagnosis of colon cancer after hospital discharge for diverticular disease were calculated. Colon cancer mortality was compared between patients with or without diverticular disease. Within 6months after an admission due to diverticular disease, OR of having a colon cancer diagnosis were up to 31.49 (19.00-52.21). After 12 months, there was no increased risk. The number of discharges for diverticular disease did not affect the risk. Colon cancer mortality did not differ between patients with and without diverticular disease. Diverticular disease does not increase the risk of colon cancer in the long term, and a history of diverticular disease does not affect colon cancer mortality. The increased risk of colon cancer within the first 12months after diagnosing diverticular disease is most likely due to surveillance and misclassification. Examination of the colon should be recommended after a primary episode of symptomatic diverticular disease. © 2011 Blackwell Publishing Ltd.

Graves' disease is a common cause of thyrotoxicosis. Treatment options include anti-thyroid medications or definitive therapy: thyroidectomy or radioactive iodine (I(131) ). Traditionally, I(131) has been the preferred definitive treatment for Graves' disease in New Zealand. Reports of concomitant thyroid cancer occurring in up to 17% of Graves' patients suggest surgery, if performed with low morbidity, may be the preferred option. The aim of this study was to determine the rate of thyroid cancer and surgical outcomes in a New Zealand cohort of patients undergoing thyroidectomy for Graves' disease. This study is a retrospective review of Waikato region patients undergoing thyroid surgery for Graves' disease during the 10-year period prior to 1 December 2011. A total of 833 patients underwent thyroid surgery. Of these, 117 were for Graves' disease. Total thyroidectomy was performed in 82, near-total in 33 and subtotal in 2 patients. Recurrent thyrotoxicosis developed in one subtotal patient requiring I(131) therapy. There were two cases of permanent hypoparathyroidism and one of permanent recurrent laryngeal nerve palsy. Eight patients (6.8%) had thyroid cancer detected, none of whom had overt nodal disease. Five were papillary microcarcinomas (one of which was multifocal), two were papillary carcinomas (11 mm and 15 mm) and one was a minimally invasive follicular carcinoma. Thyroid cancer was identified in approximately 7% of patients undergoing surgery for Graves' disease. A low complication rate (<2%) of permanent hypoparathyroidism and nerve injury (<1%) supports surgery being a safe alternative to I(131) especially for patients with young children, ophthalmopathy or compressive symptoms. © 2012 The Authors.

Besides individual care, regular follow-up studies in breast cancer patients have different aims, relative to different tumor stages at presentation. In early stages emphasis has to be laid on detection of loco-regional recurrences, which will not reduce overall survival if diagnosed and treated early. In addition, treatment effects and changes in the activity of disease are evaluated. Radiographic studies for detection of distant metastases are justified if followed by proper treatment. Early diagnosis of cancer of the opposite breast and of such cancers that are associated with breast cancer (colon, ovaries, endometrium) is imperative. The aim of a regular follow-up in more advanced tumor stages is to monitor the extent of disease and to prevent complications (e.g. fractures, spinal cord compression). In familial breast cancer first degree relatives should be included in the follow-up plan. The patient's psychosocial needs, even if not verbalized, should not be neglected. (Author)

Mortality from diseases other than cancer following low doses of ionizing radiation

Vrijheid, M; Cardis, E; Ashmore, P

2007-01-01

BACKGROUND: Ionizing radiation at very high (radio-therapeutic) dose levels can cause diseases other than cancer, particularly heart diseases. There is increasing evidence that doses of the order of a few sievert (Sv) may also increase the risk of non-cancer diseases. It is not known, however......, whether such effects also occur following the lower doses and dose rates of public health concern. METHODS: We used data from an international (15-country) nuclear workers cohort study to evaluate whether mortality from diseases other than cancer is related to low doses of external ionizing radiation....... Analyses included 275 312 workers with adequate information on socioeconomic status, over 4 million person-years of follow-up and an average cumulative radiation dose of 20.7 mSv; 11 255 workers had died of non-cancer diseases. RESULTS: The excess relative risk (ERR) per Sv was 0.24 [95% CI (confidence...

How Can We Treat Cancer Disease Not Cancer Cells?

Since molecular biology studies began, researches in biological science have centered on proteins and genes at molecular level of a single cell. Cancer research has also focused on various functions of proteins and genes that distinguish cancer cells from normal cells. Accordingly, most contemporary anticancer drugs have been developed to target abnormal characteristics of cancer cells. Despite the great advances in the development of anticancer drugs, vast majority of patients with advanced cancer have shown grim prognosis and high rate of relapse. To resolve this problem, we must reevaluate our focuses in current cancer research. Cancer should be considered as a systemic disease because cancer cells undergo a complex interaction with various surrounding cells in cancer tissue and spread to whole body through metastasis under the control of the systemic modulation. Human body relies on the cooperative interaction between various tissues and organs, and each organ performs its specialized function through tissue-specific cell networks. Therefore, investigation of the tumor-specific cell networks can provide novel strategy to overcome the limitation of current cancer research. This review presents the limitations of the current cancer research, emphasizing the necessity of studying tissue-specific cell network which could be a new perspective on treating cancer disease, not cancer cells.

Life-threatening diseases, such as head and neck cancer (HNCa), can stimulate the emergence of a new disease-specific self-concept. We hypothesized that (i) negative cancer-stereotypes invoke distancing, which inhibits the adoption of a disease-specific self-concept and (ii) patient characteristics, disease and treatment factors, and cancer-related stressors moderate the phenomenon. Head and neck cancer outpatients (N = 522) completed a semantic-differential measure of disease-specific self-concept (perceived similarity to the 'cancer patient') and other self-report measures in structured interviews. Negative cancer-stereotypes were represented by the number of semantic-differential dimensions (0-3) along which respondents evaluated the stereotypic 'cancer patient' negatively (i.e., negative valence). We tested the two-way interactions between negative valence and hypothesized moderator variables. We observed significant negative valence × moderator interactions for the following: (i) patient characteristics (education, employment, social networks); (ii) disease and treatment factors (cancer-symptom burden); and (iii) cancer-related stressors (uncertainty, lack of information, and existential threats). Negative cancer stereotypes were consistently associated with distancing of self from the stereotypic 'cancer patient,' but the effect varied across moderator variables. All significant moderators (except employment and social networks) were associated with increasing perceived similarity to the 'cancer patient' when respondents maintained negative stereotypes; perceived similarity decreased when people were employed or had extensive social networks. Moderator effects were less pronounced when respondents did not endorse negative cancer stereotypes. When they hold negative stereotypes, people with HNCa distance themselves from a 'cancer patient' identity to preserve self-esteem or social status, but exposure to cancer-related stressors and adaptive demands may

Infections caused by high-risk human papillomavirus (HPV) are responsible for 7.7% of cancers in developing countries, mainly cervical cancer. This disease is steadily increasing in sub-Saharan Africa, with more than 75,000 new cases and 50,000 deaths yearly, further increased by HIV infection. Areas covered: The current status of cervical cancer associated with HPV in sub-Saharan Africa has been systematically revised. The main issues discussed here are related to the public health burden of cervical cancer in sub-Saharan Africa and predictions for the coming decades, including molecular epidemiology and determinants of HPV infection in Africa, and promising prevention measures currently being evaluated in Africa. Expert commentary: By the year 2030, cervical cancer will kill more than 443,000 women yearly worldwide, most of them in sub-Saharan Africa. The increase in the incidence of cervical cancer in Africa could counteract the progress made by African women in reducing maternal mortality and longevity. Nevertheless, cervical cancer is a potentially preventable noncommunicable disease, and intervention strategies to eliminate cervical cancer as a public health concern should be urgently implemented.

Fibrocystic breast disease has developed a major issue: the breast cancer sequence. Its involvement regarding the increse of breast cancer risk has 2 aspects: it may be either the marker of a prone tissue or a premalignant hystological deffect. Difficult differential diagnosis of benign proliferative breast lession and carcinoma led to the idea of sequency between the two: cancer does not initiate on normal mammary epithelia; it takes several proliferative stages for it to occur. In our series we analized a number of 677 breast surgical procedures where the pathologic examination reveals 115 cases (17%) of coexistence between cancer and fibrocystic breast disease. This aspect has proved to be related to earlier debut of breast cancer, suggesting that epithelial hyperplasia is a risk factor for breast cancer.

[Skin cancer as occupational disease].

Bauer, A

The incidence of epithelial skin neoplasms, such as squamous cell carcinoma and basal cell carcinoma is significantly increasing worldwide. Leisure time solar UV exposure is causative in the overwhelming majority of cases in the general population; however, occupational exposure is responsible for a certain percentage of cases. Employees with a relevant exposure to polycyclic aromatic hydrocarbons in soot, raw paraffin, coal tar, anthracene, pitch or similar substances, to sunlight in outdoor occupations as well as to arsenic and ionizing radiation have a significantly increased risk to develop occupational skin cancer compared to the general population. In the official occupational disease list in the appendix of the German by-law on occupational diseases, the following occupational diseases concerning skin cancer are listed: BK 5102 "skin cancer and carcinoma in situ caused by soot, raw paraffin, coal tar, anthracene, pitch or similar substances" (e.g. various solid paraffins, asphalt and mazut as well as mineral oils, grease, cylinder and drilling oils), BK 5103 "squamous cell carcinoma or multiple actinic keratosis caused by natural UV radiation", BK 1108 "diseases caused by arsenic and its compounds" and BK 2402 "diseases caused by ionizing radiation". For further occupational exposure to carcinogenic substances and potential occupationally acquired skin tumors, no official lists are currently available. These cancers might be considered under a special opt out paragraph in the German Social Law (§ 9 para 2 SGB VII). Tumors in scars after occupational skin trauma or occupational burns are compensated as consequences of work accidents. The current official list of occupational skin cancers and new developments for expert opinions are described in this article.

The vaccinations against human papilloma virus (HPV) are highly effective in preventing persistent infection. The level of knowledge about HPV and the consequences of an infection with this virus are low in the general population and in patients who suffer from HPV-associated diseases. We aimed to compare the level of knowledge about HPV and about the women's individual malignant disease between women with and without HPV-associated gynecologic cancer as well as the knowledge about individual malignant diseases. In a pilot study, 51 women with HPV-related cancer (cervical cancer: n=30; vulvar or vaginal cancer: n=21) and 60 women with non-HPV associated gynecologic malignancies (ovarian cancer: n=30; endometrial cancer, n=30) were included. They answered a questionnaire including questions about personal medical history, risk factors for cancer development, and HPV. The general level of knowledge of the term "HPV" was low (29.7%, 33/111) and it was similar in patients with HPV-related and non-HPV-associated cancer (18/60, 30.0% vs. 15/51, 29.4%, respectively; p=1.000). When asked about their disease, 80% (24/30) of women with ovarian cancer correctly named their diagnosis, followed by women with cervical cancer (73.3%, 22/30), endometrial cancer (70%, 21/30) and vaginal or vulvar cancer (42.9%, 9/21; p=0.008). The level of knowledge about HPV and the malignant diseases the patient suffered from was low. This applied even to patients with HPV associated malignancies.

Risk Factors for Breast Cancer, Including Occupational Exposures

Full Text Available The knowledge on the etiology of breast cancer has advanced substantially in recent years, and several etiological factors are now firmly established. However, very few new discoveries have been made in relation to occupational risk factors. The International Agency for Research on Cancer has evaluated over 900 different exposures or agents to-date to determine whether they are carcinogenic to humans. These evaluations are published as a series of Monographs (www.iarc.fr. For breast cancer the following substances have been classified as “carcinogenic to humans” (Group 1: alcoholic beverages, exposure to diethylstilbestrol, estrogen-progestogen contraceptives, estrogen-progestogen hormone replacement therapy and exposure to X-radiation and gamma-radiation (in special populations such as atomic bomb survivors, medical patients, and in-utero exposure. Ethylene oxide is also classified as a Group 1 carcinogen, although the evidence for carcinogenicity in epidemiologic studies, and specifically for the human breast, is limited. The classification “probably carcinogenic to humans” (Group 2A includes estrogen hormone replacement therapy, tobacco smoking, and shift work involving circadian disruption, including work as a flight attendant. If the association between shift work and breast cancer, the most common female cancer, is confirmed, shift work could become the leading cause of occupational cancer in women.

Paradigm shift in cancer treatment: Cancer treatment as a metabolic disease – fusion of Eastern and Western medicine

Directory of Open Access Journals (Sweden)

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.

Co-existence of thyroid nodules with Graves' disease has been reported in various studies. 10-15% of such nodules harbor thyroid cancer with papillary thyroid cancer being the commonest. Medullary thyroid cancer (MTC) in nodules associated with Graves' disease is rare. On literature survey, we came across 11 such cases reported so far. We report a 62-year-old female with Graves' disease who also had a thyroid nodule that on fine-needle aspiration cytology and the subsequent postthyroidectomy histopathological examination was reported to be MTC.

To analyze the disease burden of liver cancer in the Chinese population in 1990 and 2013. Data from Global Burden of Diseases 2013 (GBD2013) was used to analyze the disease burden of liver cancer in China. The main outcome measurements would include mortality and disability-adjusted life years (DALY). Again, GBD global standard population in 2013 was used as the reference population to calculate the age-standardized rate. Related changes on percentage from 1990 to 2013 were calculated to analyze the changing patterns of disease burden for liver cancer in China. In 2013, a total of 358 100 people died of liver cancer, with the crude death rate as 25.85/100 000, in China. Number of deaths due to liver cancer secondary to hepatitis B was 163 600 (accounting for 45.69%). Number of deaths due to liver cancer secondary to hepatitis C was 134 200 (accounting for 37.48%) with DALY due to liver cancer appeared as 40.80 million person years. In 2013, the leading causes of DALY related to liver cancer was liver cancer secondary to hepatitis B, followed by liver cancer secondary to hepatitis C, liver cancer secondary to alcohol use, other liver cancers, with related DALYs as 4 652.0, 3 394.3, 964.3 and 592.1 thousands person years, respectively. The disease burdens of liver cancer secondary to various kinds of liver cancer were significantly higher in males than in females. Compared with 1990, the standardized mortality of liver cancer reduced by 25.00%, the DALY attributable to liver cancer increased by 16.95% and the standardized DALY rate attributable to liver cancer reduced by 33.47%. The burden of liver cancer secondary to hepatitis C became more serious and the standardized death rate increased by 106.18%, together with the standardized DALY rate increased by 91.68% in the past 23 years. Disease burden of liver cancer among young adults and the elderly were most serious. When comparing with the data in 1990, the standardized DALY rate showed declining trend in all the

Previous studies have emphasized that genetic susceptibility to breast cancer is rare and is expressed primarily as premenopausal breast cancer, bilateral breast cancer, or both. Proliferative breast disease (PBD) is a significant risk factor for the development of breast cancer and appears to be a precursor lesion. PBD and breast cancer were studied in 103 women from 20 kindreds that were selected for the presence of two first degree relatives with breast cancer and in 31 control women. Physical examination, screening mammography, and four-quadrant fine-needle breast aspirates were performed. Cytologic analysis of breast aspirates revealed PBD in 35% of clinically normal female first degree relatives of breast cancer cases and in 13% of controls. Genetic analysis suggests that genetic susceptibility causes both PBD and breast cancer in these kindreds. This study supports the hypothesis that this susceptibility is responsible for a considerable portion of breast cancer, including unilateral and postmenopausal breast cancer

Giagkou, E; Christodoulou, D K; Katsanos, K H

2016-05-01

Mouth cancer is a major health problem. Multiple risk factors for developing mouth cancer have been studied and include history of tobacco and alcohol abuse, age over 40, exposure to ultraviolet radiation, human papilloma virus infection (HPV), nutritional deficiencies, chronic irritation, and existence or oral potentially malignant lesions such as leukoplakia and lichen planus. An important risk factor for mouth cancer is chronic immunosuppression and has been extensively reported after solid organ transplantation as well as HIV-infected patients. Diagnosis of inflammatory bowel disease (IBD) is not yet considered as a risk factor for oral cancer development. However, a significant number of patients with IBD are receiving immunosuppressants and biological therapies which could represent potential oral oncogenic factors either by direct oncogenic effect or by continuous immunosuppression favoring carcinogenesis, especially in patients with HPV(+) IBD. Education on modifiable risk behaviors in patients with IBD is the cornerstone of prevention of mouth cancer. Oral screening should be performed for all patients with IBD, especially those who are about to start an immunosuppressant or a biologic. © 2015 John Wiley & Sons A/S.

1997-01-01

Purpose: To evaluate the incidence, histology, risk factors, treatment, and prognosis of breast cancer occurring after Hodgkin's disease. Materials and Methods: Sixty-five cases of breast cancer in 61 survivors of Hodgkin's lymphoma were analyzed. The median age at treatment for Hodgkin's disease was 24.1 [range (R): 13.3 - 71.8] years. Fifty-one percent had received radiotherapy alone, 47% radiation and chemotherapy, and 2% chemotherapy only. Relative and absolute risks were calculated based on 47 invasive breast cancers in 1049 women treated for Hodgkin's disease at Stanford. Results: The median age at diagnosis of breast cancer was 41.9 (R: 23.0 - 79.1) years; 76% of women were premenopausal. The median interval between Hodgkin's disease and breast cancer was 17.6 (R: 1.5 - 32.7) years with an increasing incidence beginning eight years after radiotherapy. The current relative risk of invasive breast cancer following Hodgkin's disease is 4.7 [95% confidence interval (CI): 3.4 - 6.1] with an absolute risk of 29.5 (CI: 18.8 - 40.2) excess cases per 10,000 person-years. Eighty-seven percent of breast cancers occurred in or at the margin of a prior radiotherapy field where a mean dose of 43.5 (R: 24.0 - 51.0) Gy was delivered. There was a family history of breast cancer in 31% of women. Cancers were detected by self examination (66%), screening mammography (27%), and physician examination (7%). Many tumors (60%) were located in the upper outer quadrants, corresponding to the axillary portion of a mantle field. There were seven cases of carcinoma in situ: six DCIS and one LCIS. The histologic distribution of invasive tumors paralleled that reported in the general population: 4% pure lobular, 35% high grade ductal, 45% intermediate grade ductal, 7% low-grade ductal, 4% tubular, 2% medullary, and 2% mucinous. Estrogen receptors were positive in 59% of evaluable cases. While 90% of invasive tumors were smaller than four centimeters, 96% were managed with mastectomy

Genetic basis of kidney cancer: Role of genomics for the development of disease-based therapeutics

Kidney cancer is not a single disease; it is made up of a number of different types of cancer, including clear cell, type 1 papillary, type 2 papillary, chromophobe, TFE3, TFEB, and oncocytoma. Sporadic, nonfamilial kidney cancer includes clear cell kidney cancer (75%), type 1 papillary kidney cancer (10%), papillary type 2 kidney cancer (including collecting duct and medullary RCC) (5%), the microphalmia-associated transcription (MiT) family translocation kidney cancers (TFE3, TFEB, and MITF), chromophobe kidney cancer (5%), and oncocytoma (5%). Each has a distinct histology, a different clinical course, responds differently to therapy, and is caused by mutation in a different gene. Genomic studies identifying the genes for kidney cancer, including the VHL, MET, FLCN, fumarate hydratase, succinate dehydrogenase, TSC1, TSC2, and TFE3 genes, have significantly altered the ways in which patients with kidney cancer are managed. While seven FDA-approved agents that target the VHL pathway have been approved for the treatment of patients with advanced kidney cancer, further genomic studies, such as whole genome sequencing, gene expression patterns, and gene copy number, will be required to gain a complete understanding of the genetic basis of kidney cancer and of the kidney cancer gene pathways and, most importantly, to provide the foundation for the development of effective forms of therapy for patients with this disease.

2011-01-01

Periodontal disease is a chronic destructive disease which occurs in adults, young people, and children. Periodontal disease and periodontal pathogens have been associated with several systemic diseases and more recently, several studies have suggested the relationship between periodontal disease and cancer. Studies with adjustment for the effect of smoking exposure, have found significant positive associations with different cancer sites. This review has outlined recent epidemiologic researches pointing to a possible role for tooth loss and periodontal disease in carcinogenesis. In this review, articles were selected from PubMed between1995 and June 2010 including human. Amongst 5,984 articles identified from the electronic search, 17 articles were selected for a full-text reading based on the inclusion and the exclusion criteria. Nine out of 10 case-control studies reported a significant increase in the risk of oral cancer in patients with periodontitis and one with no significant association. Among 6 studies examining esophageal cancer and periodontal disease, 5 studies found a significant association between them and one study failed to find a significant increased risk of cancer. Also amongst 5 studies which focused on upper gastrointestinal, gastric cancer, and periodontal disease, 4 studies found an increased risk of cancer while one study did not report any relationship. In lung cancer evaluations, 3 out of 4 studies showed some levels of association between lung cancer and periodontal disease but after adjustment for smoking, no relationship were found. Three cohort studies have evaluated overall cancer rates in periodontal patients; two of them found small but significant association between cancers and periodontal disease. The results indicate that there is a possible link between cancer and severe periodontal disease after adjustment for smoking and drinking habits.

Alcohol and tobacco consumption are closely correlated and published results on their association with breast cancer have not always allowed adequately for confounding between these exposures. Over 80% of the relevant information worldwide on alcohol and tobacco consumption and breast cancer were collated, checked and analysed centrally. Analyses included 58,515 women with invasive breast cancer and 95,067 controls from 53 studies. Relative risks of breast cancer were estimated, after stratifying by study, age, parity and, where appropriate, women's age when their first child was born and consumption of alcohol and tobacco. The average consumption of alcohol reported by controls from developed countries was 6.0 g per day, i.e. about half a unit/drink of alcohol per day, and was greater in ever-smokers than never-smokers, (8.4 g per day and 5.0 g per day, respectively). Compared with women who reported drinking no alcohol, the relative risk of breast cancer was 1.32 (1.19-1.45, P/=45 g per day alcohol. The relative risk of breast cancer increased by 7.1% (95% CI 5.5-8.7%; P<0.00001) for each additional 10 g per day intake of alcohol, i.e. for each extra unit or drink of alcohol consumed on a daily basis. This increase was the same in ever-smokers and never-smokers (7.1% per 10 g per day, P<0.00001, in each group). By contrast, the relationship between smoking and breast cancer was substantially confounded by the effect of alcohol. When analyses were restricted to 22 255 women with breast cancer and 40 832 controls who reported drinking no alcohol, smoking was not associated with breast cancer (compared to never-smokers, relative risk for ever-smokers=1.03, 95% CI 0.98-1.07, and for current smokers=0.99, 0.92-1.05). The results for alcohol and for tobacco did not vary substantially across studies, study designs, or according to 15 personal characteristics of the women; nor were the findings materially confounded by any of these factors.

Cutaneous malignancies have been significantly associated with autoimmune connective tissue diseases (ACTDs). This review focuses on the current state of knowledge on skin cancer risk in the most prevalent ACTDs in dermatology including lupus erythematosus, scleroderma, dermatomyositis and Sjögren syndrome. Potential pathogenetic mechanisms for the association between ACTDs and malignancy involve disease-related impairment of immune system, sustained cutaneous inflammation, drug-associated immune suppression and increased susceptibility to acquired viral infections. An additional causal role might be played by environmental factors such as UV exposure and smoking. The occurrence of skin cancer can have a profound impact on the already compromised quality of life of ACTD patients. Therefore, effective screening and monitoring strategies are essential for ACTD patients as early detection and prompt therapeutic intervention can reduce morbidity and mortality in these patients.

Risk of Hodgkin's disease and other cancers after infectious mononucleosis

2000-01-01

BACKGROUND: Infectious mononucleosis, which is caused by the Epstein-Barr virus, has been associated with an increased risk for Hodgkin's disease. Little is known, however, about how infectious mononucleosis affects long-term risk of Hodgkin's disease, how this risk varies with age at infectious...... mononucleosis diagnosis, or how the risk for Hodgkin's disease varies in different age groups. In addition, the general cancer profile among patients who have had infectious mononucleosis has been sparsely studied. METHODS: Population-based cohorts of infectious mononucleosis patients in Denmark and Sweden were...... statistical tests including the trend tests were two-sided. RESULTS: A total of 1381 cancers were observed during 689 619 person-years of follow-up among 38 562 infectious mononucleosis patients (SIR = 1. 03; 95% confidence interval [CI] = 0.98-1.09). Apart from Hodgkin's disease (SIR = 2.55; 95% CI = 1...

End Stage and Chronic Kidney Disease: Associations with Renal Cancer

International Nuclear Information System (INIS)

Russo, Paul

2012-01-01

There is a well known association between end stage renal disease and the development of kidney cancer in the native kidney of patients requiring renal replacement therapy. There is now emerging evidence that lesser degrees of renal insufficiency (chronic kidney disease, CKD) are also associated with an increased likelihood of cancer in general and kidney cancer in particular. Nephropathological changes are commonly observed in the non-tumor bearing portions of kidney resected at the time of partial and radical nephrectomy (RN). In addition, patients with renal cancer are more likely to have CKD at the time of diagnosis and treatment than the general population. The exact mechanism by which renal insufficiency transforms normal kidney cells into tumor cells is not known. Possible mechanisms include uremic immune inhibition or increased exposure to circulating toxins not adequately cleared by the kidneys. Surgeons managing kidney tumors must have an increased awareness of their patient’s renal functional status as they plan their resection. Kidney sparing approaches, including partial nephrectomy (PN) or active surveillance in older and morbidly ill patients, can prevent CKD or delay the further decline in renal function which is well documented with RN. Despite emerging evidence that PN provides equivalent local tumor control to RN while at the same time preventing CKD, this operation remains under utilized in the United States and abroad. Increased awareness of the bi directional relationship between kidney function and kidney cancer is essential in the contemporary management of kidney cancer.

Autosomal dominant polycystic kidney disease (ADPKD), the most common form of polycystic kidney disease (PKD), is a disorder with characteristics of neoplasia. However, it is not known whether renal transplant recipients with PKD have an increased risk of cancer. Data from the Scientific Registry of Transplant Recipients, which contains information on all solid organ transplant recipients in the United States, were linked to 15 population-based cancer registries in the United States. For PKD recipients, we compared overall cancer risk with that in the general population. We also compared cancer incidence in PKD versus non-PKD renal transplant recipients using Poisson regression, and we determined incidence rate ratios (IRRs) adjusted for age, sex, race/ethnicity, dialysis duration, and time since transplantation. The study included 10,166 kidney recipients with PKD and 107,339 without PKD. Cancer incidence in PKD recipients was 1233.6 per 100,000 person-years, 48% higher than expected in the general population (standardized incidence ratio, 1.48; 95% confidence interval [95% CI], 1.37 to 1.60), whereas cancer incidence in non-PKD recipients was 1119.1 per 100,000 person-years. The unadjusted incidence was higher in PKD than in non-PKD recipients (IRR, 1.10; 95% CI, 1.01 to 1.20). However, PKD recipients were older (median age at transplantation, 51 years versus 45 years for non-PKD recipients), and after multivariable adjustment, cancer incidence was lower in PKD recipients than in others (IRR, 0.84; 95% CI, 0.77 to 0.91). The reason for the lower cancer risk in PKD recipients is not known but may relate to biologic characteristics of ADPKD or to cancer risk behaviors associated with ADPKD.

The association of pioglitazone and urinary tract disease in type 2 diabetic Taiwanese: bladder cancer and chronic kidney disease.

Directory of Open Access Journals (Sweden)

Mei-Yueh Lee

Full Text Available OBJECTIVE: Although studies have shown an association between pioglitazone and bladder cancer, the associated factors have not been identified. The aim of this study was to investigate the factors that may link pioglitazone to bladder cancer. MATERIALS AND METHODS: In total, 34,970 study subjects were identified from the National Health Insurance Research Database in 2003 with follow-up from 2005 to 2009. The demographic characteristics of patients who had used and had never used pioglitazone, including age, sex, diabetes duration, urinary tract disease, nephropathy, bladder cancer, and cumulative dose and duration of pioglitazone therapy, were analyzed using the χ2 test. Cox proportional hazard regression models were used to determine the independent effects of pioglitazone on bladder cancer and newly developed chronic kidney disease. RESULTS: Among 3,497 ever users and 31,473 never users of pioglitazone, the respective incident cases of bladder cancer were 12 (0.4% and 72 (0.2%, and for newly developed chronic kidney disease 245 (8.1% and 663 (2.3%, respectively. Ever use of pioglitazone [1.59(1.32-1.91], cumulative dose of pioglitazone 10,500 mg [1.34 (1.04-1.73], and duration of therapy 12 months [1.39 (1.09-1.76] were associated with the development of chronic kidney disease. CONCLUSIONS: There was no association of pioglitazone use with bladder cancer development, however, there was an association with an increased risk of newly developed chronic kidney disease.

Chemokine Function in Periodontal Disease and Oral Cavity Cancer

Sahingur, Sinem Esra; Yeudall, W. Andrew

2015-01-01

The chemotactic cytokines, or chemokines, comprise a superfamily of polypeptides with a wide range of activities that include recruitment of immune cells to sites of infection and inflammation, as well as stimulation of cell proliferation. As such, they function as antimicrobial molecules and play a central role in host defenses against pathogen challenge. However, their ability to recruit leukocytes and potentiate or prolong the inflammatory response may have profound implications for the progression of oral diseases such as chronic periodontitis, where tissue destruction may be widespread. Moreover, it is increasingly recognized that chronic inflammation is a key component of tumor progression. Interaction between cancer cells and their microenvironment is mediated in large part by secreted factors such as chemokines, and serves to enhance the malignant phenotype in oral and other cancers. In this article, we will outline the biological and biochemical mechanisms of chemokine action in host–microbiome interactions in periodontal disease and in oral cancer, and how these may overlap and contribute to pathogenesis.

In the present study we review and discuss the current evidence and suggest how to proceed in the management of oligometastatic disease in upper gastrointestinal cancer. An electronic search of the PubMed database for relevant articles was performed. Both the search for 'oligometastasis', 'oligometastases', 'oligometastatic', 'oligometastatic disease' as well as 'esophageal' and 'esophageal cancer' and the search for 'oligometastasis', 'oligometastases', 'oligometastatic', 'oligometastatic disease' as well as 'gastric', 'gastric cancer', 'stomach', and 'stomach cancer' yielded very few studies. Most data need to be extrapolated in general studies on oligometastatic diseases of different origins. No randomized controlled trial could be found. In the absence of data to formulate recommendations on how to proceed in the treatment of oligometastatic disease in upper gastrointestinal cancer, a more aggressive treatment of oligometastatic disease can be considered in patients whose tumors show a more favorable neoplastic behavior after the 'test of time'. The RENAISSANCE study will certainly deliver important data regarding this aspect.

Inflammatory bowel disease and colorectal cancer

Andreja Ocepek

2006-12-01

Full Text Available Background: Colorectal cancer is one of the most frequent cancers in developed countries and Slovenia, and the incidence is still rising. Groups of people with higher risk for colorectal cancer are well defined. Among them are patients with inflammatory bowel disease. The risk is highest in patients in whom whole large bowel is affected by inflammation, it rises after 8 to 10 years and increases with the duration of the disease. Precancerous lesion is a displastic, chronically inflammed mucosa and not an adenoma as in cases of sporadic colorectal carcinoma.Conclusions: Many studies suggest that the influence of genetic factors differs between sporadic and inflammatory bowel disease related colorectal cancer. Symptomatic patients at the time of diagnosis have a much worse prognosis. The goal of prevention programes is therefore discovering early precancerous lesions. Established screening protocols are based on relatively frequent colonoscopies which are inconvinient for the patient as well as the endoscopist. Use of specific genetic markers, mutations of candidate genes, as a screening method and a prognostic predictor could greatly lighten therapeutic decisions.

Electromagnetic fields and health effects-epidemiologic studies of cancer, diseases of the central nervous system and arrhythmia-related heart disease

Johansen, C.

2004-07-01

This epidemiologic investigation comprised separate studies of the risk of cancer, cause-specific mortality rates, risks for neurodegenerative diseases, and the risk of arrhythmia-related heart disease among employees exposed to extremely low- frequency (50-Hz) electromagnetic fields (EMF) in the Danish utility industry. All the employees in this industry were followed-up in several registers. The risk of disease was analyzed in relation to occupational exposure to EMF, latency, and duration of employment. A specific job-exposure matrix was developed and validated by comparison with direct measurements of EMF during a workday. Linkage with the Danish Cancer Register did not identify increased risks for the cancers suggested a priori to be associated with exposure to EMF, including leukemia, brain tumors, and breast cancer. Significantly increased risks for lung cancer and mesothelioma were identified for workers highly exposed to asbestos. Linkage with the National Mortality Register revealed a significantly increased overall mortality rate from amyotrophic lateral sclerosis (ALS), with an increasing trend with duration of employment and EMF exposure. In addition, a significantly increased mortality rate from electric accidents was observed. It was hypothesized that the observation of increased mortality from ALS was associated with exposure to EMF or electric shocks. No increased mortality rate from cardiovascular or cerebrovascular disease was observed. Linkage with the National Hospital Register also revealed an increased risk of ALS and, thereby confirmed the finding of an increased mortality rate for this disease in the previous study. Linkage of the cohort with the Multiple Sclerosis Register revealed an increased risk of multiple sclerosis, which was not, however, significant Linkage with the Pacemaker Register showed no increased risk of severe arrhythmia-related heart disease. The second part of the study included the establishment of a large, nationwide

It has been suggested that breast and thyroid diseases may be linked. The aim of this study was to investigate the association between benign breast disease and subsequent risk of thyroid cancer. Postmenopausal women (n = 133,875) aged 50-79 years were followed up for a mean of 14 years. Benign breast disease was defined by history of biopsy. Incident thyroid cancer cases were confirmed by medical record review. Multivariable Cox proportional hazard modeling was used to estimate hazard ratios. There were 370 incident thyroid cancer cases during the follow-up period. Compared to women without BBD, women with BBD had a significant increased risk of thyroid cancer after adjusting for potential confounders (HR 1.38 95% CI 1.10-1.73), especially for women with more than two biopsies (HR 1.59 95% CI 1.10-2.26). There were no significant differences in thyroid tumor size, stage or histologic types between women with and without BBD. Our large prospective study observed that postmenopausal women with BBD had an increased risk for thyroid cancer compared with women without BBD. A more detailed investigation of thyroid cancer risk according to different subtypes of benign breast disease is needed to better understand the association observed between thyroid and benign breast diseases.

Bilateral breast cancer after cured Hodgkin's disease

International Nuclear Information System (INIS)

Anderson, N.; Lokich, J.

1990-01-01

Three patients developed bilateral breast cancer at 10 to 24 years after mantle irradiation for locally or systemically advanced Hodgkin's disease (HD). Four of the six cancers in the three patients were detected only by mammography. Pathologically, five of the cancers were intraductal carcinomas (four with an invasive component) with one being a lobular carcinoma. Five of the six lesions were Stage I pathologically without evidence of axillary nodal involvement. It is recommended that female patients with Hodgkin's disease who have received mantle irradiation as part of the therapy for their Hodgkin's disease and who are observed for 10 or more years after completion of mantle irradiation be considered at risk for the development of breast cancer. Such patients should be monitored appropriately by routine bilateral mammograms to increase the early detection of early stage lesions

Extramammary Paget disease (EMPD) is a rare skin disease commonly found in the anogenital region. In this study, we aimed to identify EMPD patients seen in the non-melanoma skin cancer clinic at Odette Cancer Centre and to describe the treatments delivered and outcomes achieved. From 2000 to 2009, 14 patients were seen. Initial treatment recommendations included imiquimod and surgical excision, although half the patients required more than one treatment modality, highlighting the difficulty of achieving complete eradication of this disease.

To examine and compare awareness of lifestyle risk factors for cancer and heart disease in a single UK representative sample. Two open-ended questions about cancer and heart disease risk factors were included in a population-based survey of 1747 adults. Responses were coded for four lifestyles with established links to both diseases: smoking, eating an unhealthy diet, drinking excessive alcohol and physical inactivity. Awareness of lifestyle risk factors was low for both diseases, although higher for heart disease than cancer. The average number identified by respondents was 2.1 (heart disease) and 1.4 (cancer). The strongest predictor was education (both pUnhealthy lifestyles make a significant contribution to ill health and mortality. Increased public awareness of the links between lifestyles and commonly feared diseases might help people understand the potential health consequences of their actions and encourage them to make much-needed lifestyle changes. Efforts are needed to improve public health messages about how lifestyle risk factors impact on the chances of developing these important diseases.

Cancer is caused by genetic alterations, but only 10% of the cancer diseases are inherited. The probability for an individual or a family of having inherited cancer, individual consequences of the respective results of genetic testing, as well as its costs and reimbursement by the health insurance must be addressed by expert genetic counseling which at-risk requires special expertise. Identification of a germline mutation which may predispose to a variety of different cancer types allows determination of an individual's specific life time risk in symptomatic as well as in a-symptomatic family members. Identification of the underlying defective gene in heritable cancer disorders also enables optimized preventive and novel therapeutic approaches specifically targeting the underlying molecular pathomechanisms.

Rhabdoviruses as vaccine platforms for infectious disease and cancer.

Zemp, Franz; Rajwani, Jahanara; Mahoney, Douglas J

2018-05-21

The family Rhabdoviridae (RV) comprises a large, genetically diverse collection of single-stranded, negative sense RNA viruses from the order Mononegavirales. Several RV members are being developed as live-attenuated vaccine vectors for the prevention or treatment of infectious disease and cancer. These include the prototype recombinant Vesicular Stomatitis Virus (rVSV) and the more recently developed recombinant Maraba Virus, both species within the genus Vesiculoviridae. A relatively strong safety profile in humans, robust immunogenicity and genetic malleability are key features that make the RV family attractive vaccine platforms. Currently, the rVSV vector is in preclinical development for vaccination against numerous high-priority infectious diseases, with clinical evaluation underway for HIV/AIDS and Ebola virus disease. Indeed, the success of the rVSV-ZEBOV vaccine during the 2014-15 Ebola virus outbreak in West Africa highlights the therapeutic potential of rVSV as a vaccine vector for acute, life-threatening viral illnesses. The rVSV and rMaraba platforms are also being tested as 'oncolytic' cancer vaccines in a series of phase 1-2 clinical trials, after being proven effective at eliciting immune-mediated tumour regression in preclinical mouse models. In this review, we discuss the biological and genetic features that make RVs attractive vaccine platforms and the development and ongoing testing of rVSV and rMaraba strains as vaccine vectors for infectious disease and cancer.

Gab Docking Proteins in Cardiovascular Disease, Cancer, and Inflammation

Directory of Open Access Journals (Sweden)

Yoshikazu Nakaoka

2013-01-01

Full Text Available The docking proteins of the Grb2-associated binder (Gab family have emerged as crucial signaling compartments in metazoans. In mammals, the Gab proteins, consisting of Gab1, Gab2, and Gab3, are involved in the amplification and integration of signal transduction evoked by a variety of extracellular stimuli, including growth factors, cytokines, antigens, and other molecules. Gab proteins lack the enzymatic activity themselves; however, when phosphorylated on tyrosine residues, they provide binding sites for multiple Src homology-2 (SH2 domain-containing proteins, such as SH2-containing protein tyrosine phosphatase 2 (SHP2, phosphatidylinositol 3-kinase regulatory subunit p85, phospholipase Cγ, Crk, and GC-GAP. Through these interactions, the Gab proteins transduce signals from activated receptors into pathways with distinct biological functions, thereby contributing to signal diversification. They are known to play crucial roles in numerous physiological processes through their associations with SHP2 and p85. In addition, abnormal Gab protein signaling has been linked to human diseases including cancer, cardiovascular disease, and inflammatory disorders. In this paper, we provide an overview of the structure, effector functions, and regulation of the Gab docking proteins, with a special focus on their associations with cardiovascular disease, cancer, and inflammation.

This paper investigates the association between individually measured socioeconomic status (SES) and all-cause survival in colorectal cancer patients, and explores whether factors related to the patient, the disease, or the surgical treatment mediate the observed social gradient. The data were...... on comorbidity from previous hospitalizations and use of medication. Only patients with colorectal cancer as their first primary tumour and those born after 1920 were included. A total of 8763 patients were included in the study. Cox proportional hazard regression models revealed a positive social gradient......, while no evidence of a mediating effect was found for disease or surgical treatment factors. This indicates that the difference in survival among colorectal cancer patients from different social groups was probably not caused by unintentional differences in treatment factors related to surgery...

Over 3 years, concurrent chemoradiotherapy was performed in 16 patients with advanced esophageal cancer (clinical Stage IV) and suspected noncurative resection. The subjects were {>=}A3 or N3, or were stage IV with distant metastasis on preoperative diagnosis. Two courses of 5FU and CDDP were given with concurrent radiotherapy. The predominant side effects were nausea, vomiting and anorexia. Mild or moderate leukopenia also occurred. The response was complete remission (CR) in two patients, partial remission (PR) in eight, minor response (MR) in two, no change (NC) in two and progressive disease (PD) in two. The overall response rate was 62.5%. Esophagectomy was performed in four patients (histological stage II in one, stage III in one, and stage IV in two). Two of 4 resected patients are alive (33.8 months), while the other died of unrelated causes. One of the 6 non-resected PR patients has survived for 18 months, but all other patients died of cancer within nine months of starting treatment. The survival rate of 16 patients undergoing chemoradiotherapy was 16.7% at one and two years. Thus, chemoradiotherapy may improve the prognosis of advanced esophageal cancer with suspected noncurative resection by increasing the response rate and the curative resection rate. (author)

Full Text Available Cervical cancer is one of the leading gynaecological malignancies worldwide. It is an infectious disease of the cervix, associated with human papillomavirus infection (HPV, infection with bacterial agents such as Chlamydia trachomatis and Neisseria gonorrhoea as well as human immunodeficiency virus (HIV. Furthermore, it is an AIDS-defining disease with an accelerated mortality in HIV-infected women with cervical cancer. With the introduction of robust vaccination strategies against HPV in the developed world, it is anticipated that the incidence of cervical cancer will decrease in the coming years. However, vaccination has limited benefit for women already infected with high-risk HPV, and alternative therapeutic intervention strategies are needed for these women. Many pathological disorders, including cervical cancer, are characterised by the exacerbated activation and maintenance of inflammatory pathways which are considered to be regulated by infectious agents. In cervical cancer, hyperactivation of these inflammatory pathways and regulation of immune infiltrate into tissues can potentially play a role not only in tumorigenesis but also in HIV infection. In this paper we will discuss the contribution of inflammatory pathways to cervical cancer progression and HIV infection and the role of HIV in cervical cancer progression.

Cancer is the primary disease responsible for death and disability worldwide. Currently, prevention and early detection represents the best hope for cure. Knowing the expected diseases that occur with a particular cancer in advance could lead to physicians being able to better tailor their treatment for cancer. The aim of this study was to build an animated visualization tool called as Cancer Associations Map Animation (CAMA), to chart the association of cancers with other disease over time. The study population was collected from the Taiwan National Health Insurance Database during the period January 2000 to December 2002, 782 million outpatient visits were used to compute the associations of nine major cancers with other diseases. A motion chart was used to quantify and visualize the associations between diseases and cancers. The CAMA motion chart that was built successfully facilitated the observation of cancer-disease associations across ages and genders. The CAMA system can be accessed online at http://203.71.86.98/web/runq16.html. The CAMA animation system is an animated medical data visualization tool which provides a dynamic, time-lapse, animated view of cancer-disease associations across different age groups and gender. Derived from a large, nationwide healthcare dataset, this exploratory data analysis tool can detect cancer comorbidities earlier than is possible by manual inspection. Taking into account the trajectory of cancer-specific comorbidity development may facilitate clinicians and healthcare researchers to more efficiently explore early stage hypotheses, develop new cancer treatment approaches, and identify potential effect modifiers or new risk factors associated with specific cancers.

Benign breast disease and high breast density are prevalent, strong risk factors for breast cancer. Women with both risk factors may be at very high risk. We included 42818 women participating in the Breast Cancer Surveillance Consortium who had no prior diagnosis of breast cancer and had undergone at least one benign breast biopsy and mammogram; 1359 women developed incident breast cancer in 6.1 years of follow-up (78.1% invasive, 21.9% ductal carcinoma in situ). We calculated hazard ratios (HRs) using Cox regression analysis. The referent group was women with nonproliferative changes and average density. All P values are two-sided. Benign breast disease and breast density were independently associated with breast cancer. The combination of atypical hyperplasia and very high density was uncommon (0.6% of biopsies) but was associated with the highest risk for breast cancer (HR = 5.34; 95% confidence interval [CI] = 3.52 to 8.09, P < .001). Proliferative disease without atypia (25.6% of biopsies) was associated with elevated risk that varied little across levels of density: average (HR = 1.37; 95% CI = 1.11 to 1.69, P = .003), high (HR = 2.02; 95% CI = 1.68 to 2.44, P < .001), or very high (HR = 2.05; 95% CI = 1.54 to 2.72, P < .001). Low breast density (4.5% of biopsies) was associated with low risk (HRs <1) for all benign pathology diagnoses. Women with high breast density and proliferative benign breast disease are at very high risk for future breast cancer. Women with low breast density are at low risk, regardless of their benign pathologic diagnosis.

Purpose: Second malignancies have been reported among patients who were treated by radiation therapy or chemotherapy alone or in combination. Studies have implied an increased risk of breast cancer in women who received radiotherapy as part of their treatment for Hodgkin's disease. This review was performed to determine if there is an association between splenectomy and subsequent breast cancer. Methods and Materials: One hundred and thirty-six female patients with histologically proven Hodgkin's disease were seen in the Division of Radiation Oncology between 1962 and 1985. All patients received mantle or mediastinal irradiation as part of their therapy. The risk of breast cancer was assessed and multiple linear regression analysis was performed on the following variables: patient age, stage, dose and extent of radiation field, time after completing radiation therapy, splenectomy, and chemotheraphy. Results: Breast cancer was observed in 11 of 74 splenectomized patients and in none of 62 patients not splenectomized. The mean follow-up was 13 years in splenectomized patients and 16 years, 7 months in nonsplenectomized patients. Nine patients developed invasive breast cancer and two developed ductal carcinoma in situ. Splenectomy was the only variable independently associated with an increased risk of breast cancer (p < 0.005) in multiple linear regression analysis; age, latency, and splenectomy considered together were also associated with an increased risk of breast cancer (p < 0.01). Conclusion: Our data show an increased risk of breast cancer in splenectomized patients who had treatment for Hodgkin's disease. A multiinstitutional survey may better define the influence of splenectomy relative to developing breast cancer in patients treated for Hodgkin's disease. The risk of breast cancer should be considered when recommending staging laparotomy, and we recommend close follow-up examination including routine mammograms for female patients successfully treated for

The prevalence of chronic obstructive pulmonary disease (COPD) in smokers enrolled as "healthy" controls in studies is 10-50%. The COPD status of ideal smoker populations for lung cancer case-control studies should be checked via spirometry; however, this is often not feasible, because no medical indications exist for asymptomatic smokers to undergo spirometry prior to study enrollment. Therefore, there is an unmet need for robust, cost effective assays for identifying undiagnosed lung disease among asymptomatic smokers. Such assays would help excluding unhealthy smokers from lung cancer case-control studies. We used the cytokinesis-blocked micronucleus (CBMN) assay (a measure of genetic instability) to identify undiagnosed lung disease among asymptomatic smokers. We used a convenience population from an on-going lung cancer case-control study including smokers with lung cancer (n = 454), smoker controls (n = 797), and a self-reported COPD (n = 200) contingent within the smoker controls. Significant differences for all CBMN endpoints were observed when comparing lung cancer to All controls (which included COPD) and Healthy controls (with no COPD). The risk ratio (RR) was increased in the COPD group vs. Healthy controls for nuclear buds (RR 1.28, 95% confidence interval 1.01-1.62), and marginally increased for micronuclei (RR 1.06, 0.98-1.89) and nucleoplasmic bridges (RR 1.07, 0.97-1.15). These findings highlight the importance of using truly healthy controls in studies geared toward assessment of lung cancer risk. Using genetic instability biomarkers would facilitate the identification of smokers susceptible to tobacco smoke carcinogens and therefore predisposed to either disease.

Awareness of the status of disease among terminally ill cancer patients is an important part of the end-of-life care. We have evaluated how palliative care consultative service (PCCS) affects patient disease awareness and determined who may benefit from such services in Taiwan. In total, 2,887 terminally ill cancer patients consecutively received PCCS between January 2006 and December 2010 at a single medical center in Taiwan, after which they were evaluated for disease awareness. At the beginning of PCCS, 31 % of patients (n = 895) were unaware of their disease status. The characteristics of these 895 patients were analyzed retrospectively to determine variables pertinent to patient disease awareness after PCCS. In total, 485 (50 %) of the 895 patients became aware of their disease at the end of PCCS. Factors significantly associated with higher disease awareness included a longer interval between the date of hospital admission and that of PCCS referral (>4 weeks versus ≤2 weeks), a longer duration of PCCS (>14 days versus ≤7 days), the male gender, divorced marital status (versus married), and family awareness (versus lack of family awareness). Lower disease awareness was associated with older age (age > 75 years versus age = 18-65 years), referral from non-oncology departments, and primary cancer localization (lung, colon-rectum, or urological versus liver). Disease awareness is affected by multiple factors related to the patients, their families, and the clinicians. The promotion of PCCS increased disease awareness among terminally ill cancer patients in Taiwan.

Epigenetic Transgenerational Actions of Vinclozolin on the Development of Disease and Cancer

Science.gov (United States)

Skinner, Michael K.; Anway, Matthew D.

2018-01-01

Exposure to an environmental endocrine disruptor (e.g., vinclozolin) during embryonic gonadal sex determination appears to alter the male germ line epigenome and subsequently promotes transgenerational adult onset disease. The epigenetic mechanism involves the induction of new imprinted-like genes/DNA sequences in the germ line that appear to transmit disease phenotypes. The disease phenotypes include testis abnormalities, prostate disease, kidney disease, immune abnormalities, and tumor development. This epigenetic transgenerational disease mechanism provides a unique perspective from which to view inheritable adult onset disease states, such as cancer, and ultimately offers new insights into novel diagnostic and therapeutic strategies.

Cancer: a single disease with a multitude of manifestions?

Directory of Open Access Journals (Sweden)

Grandics Peter

2003-01-01

Full Text Available Abstract The relationships of critical nutrients such as plant phenolics, vitamins, minerals and lipids are considered with respect to the incidence of a variety of cancers, and analyzed in terms of how these nutrient deficiencies alter immune function, DNA integrity and cell proliferation. With a significant correlation found between cancer and these nutrient deficiencies, the hypothesis is presented here that nutrition could provide a unifying perception of cancer and recast it as a single disease. This further suggests that a coordinated administration of specific, critical nutrients to cancer patients could lead to the reversal of the disease. It is also proposed that the concurrent presence of a variety of nutritional deficiencies in cancer patients requires a multilevel, systemic approach to this disease as opposed to the single active therapeutic agent approach that is the cornerstone of contemporary research and pharmacology.

Rationale: Previous respiratory diseases have been associated with increased risk of lung cancer. Respiratory conditions often co-occur and few studies have investigated multiple conditions simultaneously. Objectives: Investigate lung cancer risk associated with chronic bronchitis, emphysema, tuberculosis, pneumonia, and asthma. Methods: The SYNERGY project pooled information on previous respiratory diseases from 12,739 case subjects and 14,945 control subjects from 7 case–control studies conducted in Europe and Canada. Multivariate logistic regression models were used to investigate the relationship between individual diseases adjusting for co-occurring conditions, and patterns of respiratory disease diagnoses and lung cancer. Analyses were stratified by sex, and adjusted for age, center, ever-employed in a high-risk occupation, education, smoking status, cigarette pack-years, and time since quitting smoking. Measurements and Main Results: Chronic bronchitis and emphysema were positively associated with lung cancer, after accounting for other respiratory diseases and smoking (e.g., in men: odds ratio [OR], 1.33; 95% confidence interval [CI], 1.20–1.48 and OR, 1.50; 95% CI, 1.21–1.87, respectively). A positive relationship was observed between lung cancer and pneumonia diagnosed 2 years or less before lung cancer (OR, 3.31; 95% CI, 2.33–4.70 for men), but not longer. Co-occurrence of chronic bronchitis and emphysema and/or pneumonia had a stronger positive association with lung cancer than chronic bronchitis “only.” Asthma had an inverse association with lung cancer, the association being stronger with an asthma diagnosis 5 years or more before lung cancer compared with shorter. Conclusions: Findings from this large international case–control consortium indicate that after accounting for co-occurring respiratory diseases, chronic bronchitis and emphysema continue to have a positive association with lung cancer.

Before 2008, Cancer Care Ontario (CCO) undertook provincial cancer control quality-improvement initiatives on a programmatic basis. CCO has now added Disease Pathway Management (DPM) to its quality improvement strategy, with the intent of achieving high-quality care, processes, and patient experience across the patient pathway for specific cancers. The three goals of DPM are: to describe and share evidence-based best practice along the cancer continuum for specific cancers; identify quality-improvement priorities for specific cancers and catalyze action; monitor performance against best practice for specific cancers. The objective of this article is to describe the process by which the CCO lung cancer (LC) DPM was initiated and some of its early successes. In 2009, LC DPM began with a draft LC disease pathway map and the establishment of five multidisciplinary working groups, each focused on a phase of the LC patient journey: prevention, screening, and early detection; diagnosis; treatment; palliative care, end-of-life care, and survivorship; and patient experience. The working groups held 25 meetings of 2-hour duration and developed concepts for 17 quality-improvement projects across the patient journey. Eight were selected for detailed discussion at a provincial consensus conference, which provided input on priorities for action. A report on the priorities for action was prepared and widely circulated, and regional roadshows were held in all 14 regions of the province of Ontario. Region-specific data on incidence, stage, treatment compliance, and wait times among other issues relevant to LC, were shared with the regional care providers at these roadshows. Funding was provided by CCO to address opportunities for regional improvement based on the data and the priorities identified. The LC disease pathways were refined through substantial multidisciplinary discussion, and the diagnostic pathway was posted on CCO's Web site in February 2012. The treatment pathways

The risk of colorectal cancer (CRC) and dysplasia in patients with inflammatory bowel disease (IBD) has been highly debated as risk estimates from different studies vary greatly. The present national Danish guideline on colonoscopy surveillance for dysplasia and colorectal cancer in patients......, in some subgroups of patients the risk is increased. These subgroups of patients, who should be offered colonoscopy surveillance, include patients with ulcerative colitis having extensive disease and a long disease duration (10-13 years); early age at onset (less than 19 years of age) of ulcerative...... colitis; and patients with ulcerative colitis as well as Crohn´s disease with a concomitant diagnosis of primary sclerosing cholangitis. A colonoscopy surveillance program is recommended in these subgroups with intervals ranging from every 3-6 months to every 5 years, using chromoendoscopy with targeted...

The number of cancer survivors is steadily increasing and these patients often experience long-lasting health problems. To make care for cancer survivors sustainable for the future, it would be relevant to put the effects of cancer in this phase into perspective. Therefore, the authors compared health-related quality of life (HRQOL) and health care use among cancer survivors with that of patients with chronic diseases. Patients diagnosed at age >18 years with a cancer with a 5-year survival rate > 20% and no distant metastases at the time of diagnosis and patients aged >18 years with physician-diagnosed somatic chronic diseases without cancer were sent a questionnaire. HRQOL was measured with the RAND-36, a measure of HRQOL. Self-reported health care use was measured for general practitioner care, specialist care, rehabilitative care, physical therapy, ambulatory mental health care, and occupational health care. A total of 601 cancer survivors and 1052 patients with chronic diseases without cancer were included in the current study. Multimorbidity was observed in 63% of the cancer survivors and 61% of the patients with chronic diseases. The HRQOL of the cancer survivors was significantly better than that of patients with chronic diseases after adjustment for age and sex. For the mental functioning subscale, no significant differences were found between the 2 groups. Cancer survivors were found to be less likely to have visited a general practitioner or cardiologist compared with patients with chronic diseases. When considering physical HRQOL and health care use, cancer survivors appear to fare better than the average patient with chronic diseases. No difference in mental functioning was observed in the current study. © 2016 American Cancer Society.

Immunoglobulin (Ig) G4-related sclerosing disease is a recently described systemic fibro-inflammatory disease associated with an elevated circulating level of IgG4 and extensive IgG4-positive lymphoplasmacytic infiltration, resulting in sclerosing inflammation involving various body organs. We experienced one case where surgery confirmed IgG4-related sclerosing disease as a solitary lung mass mimicking lung cancer. We report radiologic findings including chest computed tomography and positron emission tomography computed tomography, with clinical manifestations of IgG4-related sclerosing disease.

The association between cancer and immune-mediated rheumatic conditions is controversial, especially as far as polymyalgia rheumatica (PMR) is concerned. Furthermore, no clinical feature has been shown to be suggestive of a paraneoplastic rheumatic syndrome. With the present study, we aim to address both these issues. The study population comprised N = 1750 patients, including N = 100 with PMR, who attended our tertiary immuno-rheumatology clinic between January 1, 2005 and November 30, 2012. A rheumatic disease was deemed paraneoplastic if cancer had been diagnosed in the 2 years preceding or following its onset. The probability of a significant association between a specific rheumatic disease and cancer was evaluated by computing the odds ratio (OR): N = 702 patients with osteoarthritis serving as controls. Furthermore, clinical features distinguishing paraneoplastic rheumatic diseases were searched for by univariate and multivariate analysis. Sjogren's syndrome (SS) [OR 3.6 (CI 95% 1.7-7.5)], PMR (OR 5.1 CI 95% 2.9-8.9), dermatomyositis/polymyositis [OR 12.09 (CI 95% 2.6-55.8)] and vasculitis [OR 3.70 (CI 95% 1.81-7.52)] are associated with cancer. At multivariate analysis, older age is associated with cancer among SS patients (p = 0.03), while in the PMR group, older age, male gender, and ≥6 tender joints are independent predictors of paraneoplastic PMR (p rheumatic manifestations, including PMR. Older age, male gender and a more extensive joint involvement should be considered red flags for paraneoplastic PMR.

Purpose To examine the breast cancer risk overall among women with simple fibroadenoma or complex fibroadenoma and to examine the association of complex fibroadenoma with breast cancer through stratification of other breast cancer risks. Methods The study included women aged 18 to 85 years from the Mayo Clinic Benign Breast Disease Cohort who underwent excisional breast biopsy from 1967 through 1991. Within this cohort, women who had fibroadenoma were compared to women who did not have fibroadenoma. Breast cancer risk (observed vs expected) across fibroadenoma levels was assessed through standardized incidence ratios (SIRs) by using age- and calendar-stratified incidence rates from the Iowa Surveillance, Epidemiology, and End Results registry. Analyses were performed overall, within subgroups of involution status, with other demographic characteristics (age, year of biopsy, indication for biopsy, and family history), and with histologic characteristics, including overall impression (nonproliferative disease, proliferative disease without atypia [PDWA], or atypical hyperplasia). Results Fibroadenoma was identified in 2,136 women (noncomplex, 1,835 [85.9%]; complex, 301 [14.1%]). SIR for noncomplex fibroadenoma was 1.49 (95% CI, 1.26–1.74); for complex fibroadenoma, it was 2.27 (95% CI, 1.63–3.10) (test for heterogeneity in SIR, P=.02). However, women with complex fibroadenoma were more likely to have other, concomitant high-risk histologic characteristics (eg, incomplete involution and PDWA). In analyses stratified by involution status and PDWA, complex fibroadenoma was not an independent risk marker for breast cancer. Conclusions Complex fibroadenoma does not confer increased breast cancer risk beyond other established histologic characteristics. PMID:26264469

Pallis, Athanasios G; Syrigos, Konstantinos N

2013-12-01

It is estimated that approximately 25% of all lung cancer cases are observed in never-smokers and its incidence is expected to increase due to smoking prevention programs. Risk factors for the development of lung cancer described include second-hand smoking, radon exposure, occupational exposure to carcinogens and to cooking oil fumes and indoor coal burning. Other factors reported are infections (HPV and Mycobacterium tuberculosis), hormonal and diatery factors and diabetes mellitus. Having an affected relative also increases the risk for lung cancer while recent studies have identified several single nucleotide polymorphisms associated with increased risk for lung cancer development in never smokers. Distinct clinical, pathology and molecular characteristics are observed in lung cancer in never smokers; more frequently is observed in females and adenocarcinoma is the predominant histology while it has a different pattern of molecular alterations. The purpose of this review is to summarize our current knowledge of this disease. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

2015-12-01

A bidirectional relationship has been observed for kidney disease and cancer. On the one hand, cancer is an important complication noted in kidney disease as well as a major cause of morbidity and mortality in this group. On the other hand, improved cancer treatment has prolonged survival, but also increased the development of acute and chronic kidney disease. The combination of cancer and kidney disease makes it challenging for clinicians to provide comprehensive and safe therapies for this group of patients. As such, clinicians caring for this group must develop expertise and become competent in the practice of a newly evolving subspecialty of nephrology known as 'onco-nephrology'. This brief narrative review will focus on the cancer risk in patients with underlying kidney disease, the therapies such as erythropoiesis-stimulating agents on cancer progression and other outcomes, and the appropriate dosing of anti-cancer agents in patients with underlying kidney disease. © The Author 2015.

2017-06-30

The use of stem cell biology approaches to study adult lung progenitor cells and lung cancer has brought a variety of new techniques to the field of lung biology and has elucidated new pathways that may be therapeutic targets in lung cancer. Recent results have begun to identify the ways in which different cell populations interact to regulate progenitor activity, and this has implications for the interventions that are possible in cancer and in a variety of lung diseases. Today's better understanding of the mechanisms that regulate lung progenitor cell self-renewal and differentiation, including understanding how multiple epigenetic factors affect lung injury repair, holds the promise for future better treatments for lung cancer and for optimising the response to therapy in lung cancer. Working between platforms in sophisticated organoid culture techniques, genetically engineered mouse models of injury and cancer, and human cell lines and specimens, lung progenitor cell studies can begin with basic biology, progress to translational research and finally lead to the beginnings of clinical trials.

To determine the specific components of family history and personal characteristics related to disease perceptions about breast, colon, and ovarian cancers. Baseline, cross-sectional data on 2,505 healthy women aged 35-65 years enrolled from 41 primary care practices in the cluster-randomized Family Healthware™ Impact Trial, assessed for detailed family history and perceived risk, perceived severity, worry, and perceived control over getting six common diseases including breast, colon, and ovarian cancers. Participants provided family history information on 41,841 total relatives. We found evidence of underreporting of paternal family history and lower perceived breast cancer risk with cancer in the paternal versus maternal lineage. We observed cancer-specific perceived risks and worry for individual family history elements and also found novel "spillover" effects where a family history of one cancer was associated with altered disease perceptions of another. Having a mother with early-onset breast or ovarian cancer was strongly associated with perceived risk of breast cancer. Age, parenthood, and affected lineage were associated with disease perceptions and ran counter to empiric risks. Understanding patients' formulation of risk for multiple diseases is important for public health initiatives that seek to inform risk appraisal, influence disease perceptions, or match preventive interventions to existing risk perceptions.

Full Text Available Objectives: To develop a clinical prediction model of contribution of chronic obstructive pulmonary disease (COPD to the pathogenesis of lung cancer, by reporting the estimated prevalence and severity by GOLD criteria in a single-institution cohort of patients with newly diagnosed lung cancer. Primary objective was investigating the effects of impaired lung function with various histological cell types on crude survival, while considering the initial staging of disease extent. Materials & methods: A total of 441 patients, in this historical cohort from electronic medical records, completed spirometry prior to invasive diagnostic procedures and initial treatment of their lung cancer. All statistical analyses, including ANOVA and survival analysis, were performed using SAS version 9.1 software. Results: Estimated prevalence of COPD was 79.1% (95% confidence interval: 71.3%-82.9%. Lung function as measured by spirometry was a significant predictor of survival time in months (p<0.0001 both with and without adjusting for tumor-cell-type, age, and stage of disease. Median survival was similar (p=0.32 and longer among those patients with normal pulmonary function, those with restrictive disease patterns, and those with COPD–GOLD-1 defects. Median survival was shortest among patients with COPD–GOLD-4 impairment (p=0.001. Those patients with COPD–GOLD-2 and COPD-GOLD-3 impairment levels had intermediate survival times (p=0.003. Conclusions: This investigation suggests that strategies for early detection and slowing the progression of COPD before the development of lung cancer might increase patient survival. As demonstrated in this study, the presence and severity of COPD in lung cancer patients is an independent predictor of survival time, different from the established staging of initial extent of disease.

Early and accurate diagnosis is vital for effective treatment of both heart disease and cancer. Nuclear medicine techniques are helping to provide the vital information that doctors need to make decisions about treatment and disease management for patients

Bilateral breast cancer after cured Hodgkin's disease

Energy Technology Data Exchange (ETDEWEB)

Anderson, N.; Lokich, J. (New England Baptist Hospital, Boston, MA (USA))

1990-01-15

Three patients developed bilateral breast cancer at 10 to 24 years after mantle irradiation for locally or systemically advanced Hodgkin's disease (HD). Four of the six cancers in the three patients were detected only by mammography. Pathologically, five of the cancers were intraductal carcinomas (four with an invasive component) with one being a lobular carcinoma. Five of the six lesions were Stage I pathologically without evidence of axillary nodal involvement. It is recommended that female patients with Hodgkin's disease who have received mantle irradiation as part of the therapy for their Hodgkin's disease and who are observed for 10 or more years after completion of mantle irradiation be considered at risk for the development of breast cancer. Such patients should be monitored appropriately by routine bilateral mammograms to increase the early detection of early stage lesions.

Full Text Available Survivors of childhood cancer are at increased risk for a wide range of late effects. However, no large population-based studies have included the whole range of somatic diagnoses including subgroup diagnoses and all main types of childhood cancers. Therefore, we aimed to provide the most detailed overview of the long-term risk of hospitalisation in survivors of childhood cancer.From the national cancer registers of Denmark, Finland, Iceland, and Sweden, we identified 21,297 5-year survivors of childhood cancer diagnosed with cancer before the age of 20 years in the periods 1943-2008 in Denmark, 1971-2008 in Finland, 1955-2008 in Iceland, and 1958-2008 in Sweden. We randomly selected 152,231 population comparison individuals matched by age, sex, year, and country (or municipality in Sweden from the national population registers. Using a cohort design, study participants were followed in the national hospital registers in Denmark, 1977-2010; Finland, 1975-2012; Iceland, 1999-2008; and Sweden, 1968-2009. Disease-specific hospitalisation rates in survivors and comparison individuals were used to calculate survivors' standardised hospitalisation rate ratios (RRs, absolute excess risks (AERs, and standardised bed day ratios (SBDRs based on length of stay in hospital. We adjusted for sex, age, and year by indirect standardisation. During 336,554 person-years of follow-up (mean: 16 years; range: 0-42 years, childhood cancer survivors experienced 21,325 first hospitalisations for diseases in one or more of 120 disease categories (cancer recurrence not included, when 10,999 were expected, yielding an overall RR of 1.94 (95% confidence interval [95% CI] 1.91-1.97. The AER was 3,068 (2,980-3,156 per 100,000 person-years, meaning that for each additional year of follow-up, an average of 3 of 100 survivors were hospitalised for a new excess disease beyond the background rates. Approximately 50% of the excess hospitalisations were for diseases of the nervous

Physical Activity, Biomarkers, and Disease Outcomes in Cancer Survivors: A Systematic Review

Friedenreich, Christine M.; Courneya, Kerry S.; Siddiqi, Sameer M.; McTiernan, Anne; Alfano, Catherine M.

2012-01-01

Background Cancer survivors often seek information about how lifestyle factors, such as physical activity, may influence their prognosis. We systematically reviewed studies that examined relationships between physical activity and mortality (cancer-specific and all-cause) and/or cancer biomarkers. Methods We identified 45 articles published from January 1950 to August 2011 through MEDLINE database searches that were related to physical activity, cancer survival, and biomarkers potentially relevant to cancer survival. We used the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Statement to guide this review. Study characteristics, mortality outcomes, and biomarker-relevant and subgroup results were abstracted for each article that met the inclusion criteria (ie, research articles that included participants with a cancer diagnosis, mortality outcomes, and an assessment of physical activity). Results There was consistent evidence from 27 observational studies that physical activity is associated with reduced all-cause, breast cancer–specific, and colon cancer–specific mortality. There is currently insufficient evidence regarding the association between physical activity and mortality for survivors of other cancers. Randomized controlled trials of exercise that included biomarker endpoints suggest that exercise may result in beneficial changes in the circulating level of insulin, insulin-related pathways, inflammation, and, possibly, immunity; however, the evidence is still preliminary. Conclusions Future research directions identified include the need for more observational studies on additional types of cancer with larger sample sizes; the need to examine whether the association between physical activity and mortality varies by tumor, clinical, or risk factor characteristics; and the need for research on the biological mechanisms involved in the association between physical activity and survival after a cancer diagnosis.

This may lead to novel insights into cancer disease and inflammatory diseases and will overcome classical views on cancer and inflammation. In addition, this review will discuss how the physics of cancer and inflammation can help to reveal whether cancer cells will invade connective tissue and metastasize or how leukocytes extravasate and migrate through the tissue. In this review, the physical concepts of cancer progression, including the tissue basement membrane a cancer cell is crossing, its invasion and transendothelial migration as well as the basic physical concepts of inflammatory processes and the cellular responses to the mechanical stress of the microenvironment such as external forces and matrix stiffness, are presented and discussed. In conclusion, this review will finally show how physical measurements can improve classical approaches that investigate cancer and inflammatory diseases, and how these physical insights can be integrated into classical tumor biological approaches.

Functional microRNAs in Alzheimer’s disease and cancer: differential regulation of common mechanisms and pathways

Kelly N Holohan

2013-01-01

Full Text Available Two of the main research priorities in the United States are cancer and neurodegenerative diseases, which are attributed to abnormal patterns of cellular behavior. MicroRNAs (miRNA have been implicated as regulators of cellular metabolism, and thus are an active topic of investigation in both disease areas. There is presently a more extensive body of work on the role of miRNAs in cancer compared to neurodegenerative diseases, and therefore it may be useful to examine whether there is any concordance between the functional roles of miRNAs in these diseases. As a case study, the roles of miRNAs in Alzheimer’s disease (AD and their functions in various cancers will be compared. A number of miRNA expression patterns are altered in individuals with AD compared with healthy older adults. Among these, some have also been shown to correlate with neuropathological changes including plaque and tangle accumulation, as well as expression levels of other molecules known to be involved in disease pathology. Importantly, these miRNAs have also been shown to have differential expression and or functional roles in various types of cancer. To examine possible intersections between miRNA functions in cancer and AD, we review the current literature on eight of these miRNAs in cancer and AD, focusing on their roles in known biological pathways. We propose a pathway-driven model in which some molecular processes show an inverse relationship between cancer and neurodegenerative disease (e.g., proliferation and apoptosis whereas others are more parallel in their activity (e.g., immune activation and inflammation. A critical review of these and other molecular mechanisms in cancer may shed light on the pathophysiology of AD, and highlight key areas for future research. Conclusions from this work may be extended to other neurodegenerative diseases for which some molecular pathways have been identified but which have not yet been extensively researched for mi

Chronic Inflammation Links Cancer and Parkinson’s disease

Full Text Available An increasing number of genetic studies suggest that the pathogenesis of Parkinson’s disease (PD and cancer share common genes, pathways, and mechanisms. Despite a disruption in a wide range of similar biological processes, the end result is very different: uncontrolled proliferation and early neurodegeneration. Thus, the links between the molecular mechanisms that cause PD and cancer remain to be elucidated. We propose that chronic inflammation in neurons and tumors contributes to a microenvironment that favors the accumulation of DNA mutations and facilitates disease formation. This article appraises the key role of microglia, establishes the genetic role of COX2 and CARD15 in PD and cancer, and discusses prevention and treatment with this new perspective in mind. We examine the evidence that chronic inflammation is an important link between cancer and PD.

With the revision of the German Ordinance on Occupational Diseases, skin cancer due to UV irradiation was amended as a new occupational disease to the list of occupational diseases in Germany. The new occupational disease BK 5103 has the following wording: "Squamous cell carcinoma or multiple actinic keratosis of the skin caused by natural UV irradiation". Actinic keratoses are to be considered as multiple according to this new occupational diseases if they occur as single lesions of more than five annually, or are confluent in an area > 4 cm(2) (field cancerization). It is estimated that more than 2.5 million employees are exposed to natural UV irradiation due to their work (outdoor workers) in Germany and therefore have an increased risk of skin cancer. In this article the medical and technical prerequisites which have to be fulfilled for this new occupational disease in Germany are introduced.

Purpose: To define demographic and therapeutic associations with the risk of breast cancer in children treated for Hodgkin's disease (HD), particularly the frequency and interval to the development of contralateral breast cancer. Methods and Materials: All 398 female patients ( 12 years) were significant predictors of secondary breast cancer. Conclusions: Women surviving pediatric HD were found to have a 37-fold increase in the risk of breast cancer and a high likelihood of rapidly developing bilateral disease. Early-stage HD and age greater than 12 years at diagnosis of HD were independent risk factors. Higher radiation doses may augment risk, and pelvic radiation may be protective. Breast cancer screening methodology and frequency, plus the role of prophylaxis in patients with unilateral disease, require definition

Coffee intake is associated with reduced risk of liver cancer and chronic liver disease as reported in previous studies, including prospective ones conducted in Asian populations where hepatitis B viruses (HBVs) and hepatitis C viruses (HCVs) are the dominant risk factors. Yet, prospective studies in Western populations with lower HBV and HCV prevalence are sparse. Also, although preparation methods affect coffee constituents, it is unknown whether different methods affect disease associations. We evaluated the association of coffee intake with incident liver cancer and chronic liver disease mortality in 27,037 Finnish male smokers, aged 50-69, in the Alpha-Tocopherol, Beta-Carotene Cancer Prevention Study, who recorded their coffee consumption and were followed up to 24 years for incident liver cancer or chronic liver disease mortality. Multivariate relative risks (RRs) and 95% confidence intervals (CIs) were estimated by Cox proportional hazard models. Coffee intake was inversely associated with incident liver cancer (RR per cup per day=0.82, 95% CI: 0.73-0.93; P-trend across categories=0.0007) and mortality from chronic liver disease (RR=0.55, 95% CI: 0.48-0.63; P-trendcoffee. These findings suggest that drinking coffee may have benefits for the liver, irrespective of whether coffee was boiled or filtered.

The correct management of genitals and breast cancers and the improving of the preventional and therapeutical successes ratio involve the knowledge of the histopathological features of these nosological entities which have different origins, different risk factors, different simptomatology and also different prognosis. The descriptive evaluation of the histopathological features of the genitals and breast cancers to women from North-Eastern region of Romania. We have been included in the study 96 women (age range 23-77 years, mean 54,49) diagnosed with breast cancer, ovarian cancer, endometrial cancer and cervical cancer at the hospital admission, residency in the Obstetrics and Gynecology Clinics within 23 months. The following main parameters were assessed: histological types, stage at diagnosis, Pap test. After data collection, these have been codified and included in a MS Excel Database, in order to be processed with SPSS 16 and EpiInfo 3.5.1. (2008) Softwares. The following cases' repartition on diagnostic types was observed: breast cancer (44 cases), cervical cancer (24 cases), endometrial cancer (16 cases) and ovarian cancer (12 cases). In our study, the most affected range of age was 40-69 years for breast cancer, 30-59 years for cervical cancer, over 6 years for endometrial cancer and 50-59 years for ovarian cancer. For the cervical neoplasia, 40% of analyzed cases were in incipient stages (in situ to IB stage lessions). More than 50% of breast cancer cases have been diagnosed in advances stages (IIB to IIIC stages). For the endometrium carcinoma, 45% of cases have been identified in incipient stages (in situ to IC). The ovarian neoplasia cases have been detected, most frequently, in advanced stages (III and IV). 25% of women which participated in our study had showed cervical changes. From a histopathological point of view, for cervical neoplasia, squamous carcinoma was the most frequent type (87%), for breast neoplasia--invasive ductal carcinoma (80

Estimation of cancer risks from radiotherapy of benign diseases

Trott, K.R.; Kamprad, F.

2006-01-01

Background: The effective-dose method which was proposed by the ICRP (International Commission of Radiation Protection) for the estimation of risk to the general population from occupational or environmental, low-dose radiation exposure is not adequate for estimating the risk of cancer induction by radiotherapy of malignant or nonmalignant diseases. Methods:The risk of cancer induction by radiotherapy of benign diseases should be based on epidemiologic data directly derived from follow-up studies of patients who had been given radiotherapy for nonmalignant diseases in the past. Results: Risk factors were derived from epidemiologic studies of patients treated with irradiation for nonmalignant diseases to be used for selecting treatment options and optimizing treatment procedures. Conclusion: In most cases, cancer risks estimated by the effective-dose method may overestimate the true risks by one order of magnitude, yet in other cases even may underestimate it. The proposed method using organ-specific risk factors may be more suitable for treatment planning. (orig.)

Graves' Disease that Developed Shortly after Surgery for Thyroid Cancer.

2013-09-01

Graves' disease is an autoimmune disorder that may present with various clinical manifestations of hyperthyroidism. Patients with Graves' disease have a greater number of thyroid nodules and a higher incidence of thyroid cancer compared with patients with normal thyroid activity. However, cases in which patients are diagnosed with recurrence of Graves' disease shortly after partial thyroidectomy for thyroid cancer are very rare. Here we report a case of hyperthyroid Graves' disease that occurred after partial thyroidectomy for papillary thyroid cancer. In this case, the patient developed hyperthyroidism 9 months after right hemithyroidectomy, and antithyroglobulin autoantibody and thyroid stimulating hormone receptor stimulating autoantibody were positive. Therefore, we diagnosed Graves' disease on the basis of the laboratory test results and thyroid ultrasonography findings. The patient was treated with and maintained on antithyroid drugs. The mechanism of the recurrence of Graves' disease in this patient is still unclear. The mechanism may have been the improper response of the immune system after partial thyroidectomy. To precisely determine the mechanisms in Graves' disease after partial thyroidectomy, further studies based on a greater number of cases are needed.

2004-01-01

Previously we have reported our results on minimal residual disease in breast cancer. Briefly, B M-aspirates were collected from 817 patients at primary surgery. Tumor cells in B M were detected by immunocytochemistry using anticytokeratin-antibodies (A E1/ A E3). Analyses of the primary tumor included histological grading, vascular invasion and immunohistochemical detection of cerbB2, cathepsin D, p53 and ER/PgRexpression. These analyses were compared to clinical outcome. Median follow-up was 49 months. ITC were detected in 13.2% of the patients. The detection rate rose with increasing tumor size (p=0.011) and lymph node involvement (p<0.001). Systemic relapse and death from breast cancer occurred in 31.7% and 26.9% of the B M-positive versus 13.7% and 10.9% of B M-negative patients, respectively (p<0.001). Analyzing node-positive and node-negative patients separately, ITC-positivity was associated with poor prognosis in the node-positive group and in node-negative patients not receiving adjuvant therapy (T1N0). In multivariate analysis, ITC in B M was an independent prognostic factor together with N-, T-, ER/Pg R-status, histological grade and vascular invasion. Combination of several independent prognostic factors can classify subgroups of patients into excellent and high-risk prognosis groups. Like other groups we have investigated the clinical role of monitoring minimal residual disease before and after adjuvant therapy in breast cancer. One hundred and eighteen high risk stage II breast cancer patients entering the Scandinavian Study Group multicenter trial were randomized to 9 cycles of dose escalated and tailored FEC (5-flurouracil, epirubicin, cyclophosphamide) or standard FEC followed by high dose chemotherapy. B M samples at diagnosis and 6 months after completion of chemotherapy were assessed for the presence of I CT. Median observation time for patients was 68 months. ITC positivity in bone marrow was evaluated as a prognostic and predictive marker and

Patients managed in European or North American cancer centres have a variety of ethnic backgrounds and primary languages. To gain insight into the impact of ethnic origin, we have investigated understanding of disease status and quality of life (QoL) for 202 patients. Patients completed questionnaires in their first language (52 English, 50 Chinese, 50 Italian, 50 Spanish or Portuguese), including the Functional Assessment of Cancer Therapy - General (FACT-G) QoL instrument, questions about disease status, expectations of cure and the language and/or type of interpretation used at initial consultation. Physicians also evaluated their status of disease and expectation of cure, and performance status was estimated by a trained health professional. The initial consultation was usually provided in English (except for 32% of Chinese-speaking patients); interpretation was provided by a family member for 34% of patients with limited English proficiency (LEP) and by a bilingual member of staff for 21%. Patients underestimated their extent of disease and overestimated their probability of cure (P=0.001 and cultural differences is important for optimal management of patients with cancer.

The incidence of colon cancer varies by sex. Whether women and men show differences in extent of disease, treatment, and outcomes is not well described. We used a large population-based cohort to evaluate sex differences in colon cancer. Using the Ontario Cancer Registry, all cases of colon cancer treated with surgery in Ontario during 2002-2008 were identified. Electronic records of treatment identified use of surgery and adjuvant chemotherapy. Pathology reports for a random 25% sample of all cases were obtained, and disease characteristics, treatment, and outcomes in women and men were compared. A Cox proportional hazards model was used to identify factors associated with overall (os) and cancer-specific survival (css). The study population included 7249 patients who underwent resection of colon cancer; 49% ( n = 3556) were women. Stage of disease and histologic grade did not vary by sex. Compared with men, women were more likely to have right-sided disease (55% vs. 44%, p ≤ 0.001). Surgical procedure and lymph node yield did not differ by sex. Adjuvant chemotherapy was delivered to 18% of patients with stage ii and 64% of patients with stage iii disease; when adjusted for patient- and disease-related factors, use of adjuvant chemotherapy was similar for women and men [relative risk: 0.99; 95% confidence interval (ci): 0.94 to 1.03]. Adjusted analyses demonstrated that os [hazard ratio (hr): 0.80; 95% ci: 0.75 to 0.86] and css (hr: 0.82; 95% ci: 0.76 to 0.90) were superior for women compared with men. Long-term survival after colon cancer is significantly better for women than for men, which is not explained by any substantial differences in extent of disease or treatment delivered.

2017-01-01

The growing burden of cancer among several major noncommunicable diseases (NCDs) requires national implementation of tailored public health surveillance. For many emerging economies where emphasis has traditionally been placed on the surveillance of communicable diseases, it is critical to understand the specificities of NCD surveillance and, within it, of cancer surveillance. We propose a general framework for cancer surveillance that permits monitoring the core components of cancer control. We examine communalities in approaches to the surveillance of other major NCDs as well as communicable diseases, illustrating key differences in the function, coverage, and reporting in each system. Although risk factor surveys and vital statistics registration are the foundation of surveillance of NCDs, population-based cancer registries play a unique fundamental role specific to cancer surveillance, providing indicators of population-based incidence and survival. With an onus now placed on governments to collect these data as part of the monitoring of NCD targets, the integration of cancer registries into existing and future NCD surveillance strategies is a vital requirement in all countries worldwide. The Global Initiative for Cancer Registry Development, endorsed by the World Health Organization, provides a means to enhance cancer surveillance capacity in low- and middle-income countries. © The Author 2017.

2013-09-01

Full Text Available Graves' disease is an autoimmune disorder that may present with various clinical manifestations of hyperthyroidism. Patients with Graves' disease have a greater number of thyroid nodules and a higher incidence of thyroid cancer compared with patients with normal thyroid activity. However, cases in which patients are diagnosed with recurrence of Graves' disease shortly after partial thyroidectomy for thyroid cancer are very rare. Here we report a case of hyperthyroid Graves' disease that occurred after partial thyroidectomy for papillary thyroid cancer. In this case, the patient developed hyperthyroidism 9 months after right hemithyroidectomy, and antithyroglobulin autoantibody and thyroid stimulating hormone receptor stimulating autoantibody were positive. Therefore, we diagnosed Graves' disease on the basis of the laboratory test results and thyroid ultrasonography findings. The patient was treated with and maintained on antithyroid drugs. The mechanism of the recurrence of Graves' disease in this patient is still unclear. The mechanism may have been the improper response of the immune system after partial thyroidectomy. To precisely determine the mechanisms in Graves' disease after partial thyroidectomy, further studies based on a greater number of cases are needed.

Chronic obstructive pulmonary disease (COPD) and lung cancer result in significant morbidity and mortality worldwide. In addition to the role of environmental smoke exposure in the development of both diseases, recent epidemiological studies suggests a connection between the development of COPD and lung cancer. Furthermore, individuals with concomitant COPD and cancer have a poor prognosis when compared with individuals with lung cancer alone. The modulation of molecular pathways activated during emphysema likely lead to an increased susceptibility to lung tumor growth and metastasis. This review summarizes what is known in the literature examining the molecular pathways affecting matrix metalloproteinases (MMPs) in this process as well as external factors such as smoke exposure that have an impact on tumor growth and metastasis. Increased expression of MMPs provides a unifying link between lung cancer and COPD.

Full Text Available Abstract Background Ovarian cancer is a heterogeneous disease and prognosis for apparently similar cases of ovarian cancer varies. Recurrence of the disease in early stage (FIGO-stages I-II serous ovarian cancer results in survival that is comparable to those with recurrent advanced-stage disease. The aim of this study was to investigate if there are specific genomic aberrations that may explain recurrence and clinical outcome. Methods Fifty-one women with early stage serous ovarian cancer were included in the study. DNA was extracted from formalin fixed samples containing tumor cells from ovarian tumors. Tumor samples from thirty-seven patients were analysed for allele-specific copy numbers using OncoScan single nucleotide polymorphism arrays from Affymetrix and the bioinformatic tool Tumor Aberration Prediction Suite. Genomic gains, losses, and loss-of-heterozygosity that associated with recurrent disease were identified. Results The most significant differences (p  Conclusions The results of our study indicate that presence of two aberrations in TP53 on 17p and LOH on 19q in early stage serous ovarian cancer is associated with recurrent disease. Further studies related to the findings of chromosomes 17 and 19 are needed to elucidate the molecular mechanism behind the recurring genomic aberrations and the poor clinical outcome.

Cancer and its treatments can deleteriously affect memory. Cardiac function and insomnia can exacerbate memory problems. To examine the relationships among cardiovascular disease, insomnia, and self-reported memory problems (SRMP) in adult-onset cancer survivors. We included data from participants (41-64 year-old) of the 2007-2008 National Health and Nutrition Examination Survey, a nationally representative probability sample of the civilian, non-institutionalized population of the US. We excluded participants with brain cancer/stroke history since these conditions are expected to cause cognitive problems. Using binary logistic regression, we determined the prevalence of SRMP relative to cardiac problems and insomnia by weighting our results proportionally. We adjusted for predictors of memory problems: age, sex, race, education and general health. The sample included 2289 adults (49% females), 9% with a cancer history. The results pertain only to cancer survivors. Those with insomnia were 16 times as likely to have SRMP. Only insomnia symptoms (OR, 15.74; 95% CI, 1.73-143.30; p Insomnia accounted for 18.8% of the association between cardiac issues and SRMP, demonstrating mediation (Sobel p insomnia were not associated with SRMP (p > 0.05). We could not determine severity and time-related changes in SRMP. Likelihood of SRMP was higher in cancer survivors with a history of cardiovascular disease and insomnia symptoms.

Shah, Manish A; Kelsen, David P

2010-04-01

Gastric cancer is a cause of significant morbidity and cancer-related mortality worldwide. Despite recent advances in targeted therapy and understanding of the biology and development of the malignancy, progress in the treatment of gastric cancer has been limited. Most newly diagnosed patients will present with incurable disease, and have a median survival of less than 1 year. Although the disease has widespread ethnic and epidemiologic differences, medical management of gastric cancer does not distinguish among the various disease subtypes. The recent report of the ToGA phase III study has validated Her2 as a molecular target in this disease, supporting the concept that a greater understanding of the biology of gastric cancer subsets may improve treatment selection and overall outcome of individual patients. This article summarizes the epidemiology and ethnic variation of this disease to crystalize subtypes of gastric cancer in the context of current and future medical management of advanced disease.

2017-01-16

Asthma is one of the most frequently diagnosed respiratory diseases in the UK, and commonly co-occurs with other respiratory and allergic diseases, such as chronic obstructive pulmonary disease (COPD) and atopic dermatitis. Previous studies have shown an increased risk of lung cancer related to asthma, but the evidence is mixed when accounting for co-occurring respiratory diseases and allergic conditions. A systematic review of published data that investigate the relationship between asthma and lung cancer, accounting for co-occurring respiratory and allergic diseases, will be conducted to investigate the independent association of asthma with lung cancer. A systematic review will be conducted, and include original reports of cohort, cross-sectional and case-control studies of the association of asthma with lung cancer after accounting for co-occurring respiratory diseases. Articles published up to June 2016 will be included, and their selection will follow the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A standardised data extraction form will be developed and pretested, and descriptive analyses will be used to summarise the available literature. If appropriate, pooled effect estimates of the association between asthma and lung cancer, given adjustment for a specific co-occurring condition will be estimated using random effects models. Potential sources of heterogeneity and between study heterogeneity will also be investigated. The study will be a review of published data and does not require ethical approval. Results will be disseminated through a peer-reviewed publication. International Prospective Register for Systematic Reviews (PROSPERO) number CRD42016043341.

SAR125844 is a potent and selective inhibitor of the c-Met kinase receptor. This was an open-label, phase I, multicenter, dose-escalation, and dose-expansion trial of SAR125844 in Asian patients with solid tumors, a subgroup of whom had gastric cancer and MET amplification (NCT01657214). SAR125844 was administered by intravenous infusion (260-570 mg/m 2 ) on days 1, 8, 15, and 22 of each 28-day cycle. Objectives were to determine the maximum tolerated dose (MTD) and to evaluate SAR125844 safety and pharmacokinetic profile. Antitumor activity was also assessed. Of 38 patients enrolled (median age 64.0 years), 22 had gastric cancer, including 14 with MET amplification. In the dose-escalation cohort ( N = 19; unselected population, including three patients with MET -amplification [two with gastric cancer and one with lung cancer]), the MTD was not reached, and the recommended dose was established at 570 mg/m 2 . Most frequent treatment-emergent adverse events (AEs) were nausea (36.8%), vomiting (34.2%), decreased appetite (28.9%), and fatigue or asthenia, constipation, and abdominal pains (each 21.1%); none appeared to be dose-dependent. Grade ≥ 3 AEs were observed in 39.5% of patients and considered drug-related in 7.9%. SAR125844 exposure increased slightly more than expected by dose proportionality; dose had no significant effect on clearance. No objective responses were observed in the dose-escalation cohort, with seven patients (three gastric cancer, two colorectal cancer, one breast cancer, and one with cancer of unknown primary origin) having stable disease. Modest antitumor activity was observed at 570 mg/m 2 in the dose-expansion cohort, comprising patients with MET -amplified tumors ( N = 19). Two gastric cancer patients had partial responses, seven patients had stable disease (six gastric cancer and one kidney cancer), and 10 patients had progressive disease. Single-agent SAR125844 administered up to 570 mg/m 2 has acceptable tolerability and modest

To review the current state of breast cancer prevention from primary prevention through survivorship, highlight cross-cutting issues, and discuss strategies for clinical integration and future research. Published articles between 1985 and 2015 and original research. Cancer risk persists across the lifespan. Interprofessional strategies to reduce morbidity and mortality from cancer include primary, secondary, and tertiary prevention (survivorship). Prevention strategies across the cancer care continuum are cross-cutting and focus on measures to: prevent the onset of disease, identify and treat asymptomatic persons who have already developed risk factors or preclinical disease, and restore function, minimize the negative effects of disease, and prevent disease-related complications. Oncology nurses and advanced practice nurses are vital in the delivery of breast cancer prevention strategies. Published by Elsevier Inc.

Truth or Spin? Disease Definition in Cancer Screening.

Science.gov (United States)

Reid, Lynette

2017-08-01

Are the small and indolent cancers found in abundance in cancer screening normal variations, risk factors, or disease? Naturalists in philosophy of medicine turn to pathophysiological findings to decide such questions objectively. To understand the role of pathophysiological findings in disease definition, we must understand how they mislead in diagnostic reasoning. Participants on all sides of the definition of disease debate attempt to secure objectivity via reductionism. These reductivist routes to objectivity are inconsistent with the Bayesian nature of clinical reasoning; when they appeal to the sciences, they are inconsistent with what philosophy of biology tells us about its natural kinds. Proposals that we narrow the scope of our claims in the disease definition debates (proposing adoption of a specific disease paradigm for a specific context) are useful, but paradigms can still distort our reasoning in particular cases, even when we are self-conscious about their status. © The Author 2017.

Moroff, S.V.; Fuks, J.Z.

1986-01-01

Improved survival resulting from advances in therapy in patients with Hodgkin's disease is associated with long-term morbidity, including the potential for the development of a second solid malignancy. We report a 44-year-old man with an unusually aggressive course of thyroid carcinoma 15 years after treatment for Hodgkin's disease. In a review of the English-language literature, we found 21 cases of thyroid cancer following radiotherapy for Hodgkin's disease, with latency periods ranging from 6 to 48 years. The development of secondary thyroid cancer after high-dose neck irradiation may be related to hypothyroidism, itself a complication of radiotherapy. Thyroid function should be measured at least once a year in all patients given neck irradiation, with initiation of thyroid hormone replacement if there is evidence of sustained hypothyroidism

Adjusting a cancer mortality-prediction model for disease status-related eligibility criteria

Directory of Open Access Journals (Sweden)

Kimmel Marek

2011-05-01

Full Text Available Abstract Background Volunteering participants in disease studies tend to be healthier than the general population partially due to specific enrollment criteria. Using modeling to accurately predict outcomes of cohort studies enrolling volunteers requires adjusting for the bias introduced in this way. Here we propose a new method to account for the effect of a specific form of healthy volunteer bias resulting from imposing disease status-related eligibility criteria, on disease-specific mortality, by explicitly modeling the length of the time interval between the moment when the subject becomes ineligible for the study, and the outcome. Methods Using survival time data from 1190 newly diagnosed lung cancer patients at MD Anderson Cancer Center, we model the time from clinical lung cancer diagnosis to death using an exponential distribution to approximate the length of this interval for a study where lung cancer death serves as the outcome. Incorporating this interval into our previously developed lung cancer risk model, we adjust for the effect of disease status-related eligibility criteria in predicting the number of lung cancer deaths in the control arm of CARET. The effect of the adjustment using the MD Anderson-derived approximation is compared to that based on SEER data. Results Using the adjustment developed in conjunction with our existing lung cancer model, we are able to accurately predict the number of lung cancer deaths observed in the control arm of CARET. Conclusions The resulting adjustment was accurate in predicting the lower rates of disease observed in the early years while still maintaining reasonable prediction ability in the later years of the trial. This method could be used to adjust for, or predict the duration and relative effect of any possible biases related to disease-specific eligibility criteria in modeling studies of volunteer-based cohorts.

Differential equations with applications in cancer diseases.

Mathematical modeling is a process by which a real world problem is described by a mathematical formulation. The cancer modeling is a highly challenging problem at the frontier of applied mathematics. A variety of modeling strategies have been developed, each focusing on one or more aspects of cancer. The vast majority of mathematical models in cancer diseases biology are formulated in terms of differential equations. We propose an original mathematical model with small parameter for the interactions between these two cancer cell sub-populations and the mathematical model of a vascular tumor. We work on the assumption that, the quiescent cells' nutrient consumption is long. One the equations system includes small parameter epsilon. The smallness of epsilon is relative to the size of the solution domain. MATLAB simulations obtained for transition rate from the quiescent cells' nutrient consumption is long, we show a similar asymptotic behavior for two solutions of the perturbed problem. In this system, the small parameter is an asymptotic variable, different from the independent variable. The graphical output for a mathematical model of a vascular tumor shows the differences in the evolution of the tumor populations of proliferating, quiescent and necrotic cells. The nutrient concentration decreases sharply through the viable rim and tends to a constant level in the core due to the nearly complete necrosis in this region. Many mathematical models can be quantitatively characterized by ordinary differential equations or partial differential equations. The use of MATLAB in this article illustrates the important role of informatics in research in mathematical modeling. The study of avascular tumor growth cells is an exciting and important topic in cancer research and will profit considerably from theoretical input. Interpret these results to be a permanent collaboration between math's and medical oncologists.

Radiation effect on non-cancer diseases among a-bomb survivors

It has been well documented in the literature that radiation induces DNA damages and increases cancer risk. Besides cancer risk, the Life Span Study (LSS) on A-bomb survivors in Hiroshima and Nagasaki that has been conducted since 1950 by RERF demonstrated an increase in non-cancer death by cardiovascular diseases and chronic liver diseases (1). Since LSS analysis depends on death certificate, a physiological mechanism has not been elucidated how radiation increases the incidence of non-cancer diseases. In order to elucidate radiation effect on non-fatal disorders, RERF has conducted the Adult Health Study (AHS) since 1958 where 23,000 A-bomb survivors have been examined every other year. This study suggested that radiation exposure about 55 years before reduced the immune response to pathogens such as HB virus and Chlamydia pneumoniae, increased the levels of serum inflammatory markers, the prevalence of chronic hepatitis/liver cirrhosis and senile cataract, and the incidence of cardiovascular diseases. Our colleagues reported a dose-dependent decrease in the CD4 T cell number among A-bomb survivors (2,3). Since chronic inflammation and oxidative stress are causative of atherogenic cardiovascular diseases or cataract, we speculate a decrease in the immune response to pathogens, at least in part, is one of the mechanisms that A-bomb exposure increased non-cancer diseases. When the levels of inflammatory marker, C-reactive protein (CRP), were analyzed among subjects with evidence of Chlamydia pneumoniae infection, significantly higher levels of CRP were associated with antibodies to Chlamydia pneumoniae in those subjects receiving >1Gy than those receiving <5mGy. It is well known that high CRP is one of the risk factors of arteriosclerosis (4,5). Thus, A-bomb exposure seems to augment inflammatory response to pathogens, though of which mechanisms are not clear now.

Limited data exist concerning the unique pain characteristics of patients with non-cancer terminal diseases referred for inpatient hospice care. To define the unique pain characteristics of patients admitted to an acute inpatient hospice setting with end-stage dementia or chronic obstructive lung disease (or chronic obstructive pulmonary disease) and to compare them to patients with end-stage cancer. Retrospective patient chart review. Demographic, physiological, pain parameters, and medication utilization data were extracted. Associations between pain characteristics, medication utilization, and admission diagnoses were assessed. Analyses included descriptive statistics. In total, 146 patients admitted to an acute inpatient hospice between 1 April 2011 and 31 March 2012 with an underlying primary diagnosis of chronic obstructive pulmonary disease (n = 51), dementia (n = 48), or cancer (n = 47). Pain was highly prevalent in all diagnostic groups, with cancer patients experiencing more severe pain on admission. Cancer patients received a significantly higher cumulative opioid dose compared with dementia and chronic obstructive pulmonary disease patients. Pain control within 24 h of pain onset was achieved in less than half of all patient groups with chronic obstructive pulmonary disease patients the least likely to achieve pain control. Despite the fact that pain is the most common complaint at the end of life, pain management may be suboptimal for some primary diagnoses. Admission diagnosis is the strongest predictor of pain control. Patient with cancer achieve the best pain control, and chronic obstructive pulmonary disease patients are the least likely to have their pain adequately treated. © The Author(s) 2015.

Cancer as an immune-mediated disease

Shurin MR

Full Text Available Michael R ShurinDepartments of Pathology and Immunology, University of Pittsburgh Medical Center, Pittsburgh, PA, USAAbstract: The link between oncology and immunology has a long history and its development is forced by the necessity to develop innovative and highly efficient modalities for immunological destruction of malignant cells. The limited efficacy of surgery, chemotherapy and radiation also exemplify these issues, as these treatments do not eliminate all cancerous cells, do not address the immunosuppressive nature of the disease and can further impair the patient's immune response weakening patient's resistance to the cancer. Multidisciplinary analysis of the interaction between the immune system and cancer in preclinical and clinical settings suggests that the immune system is closely intertwined with both cancer pathogenesis and treatment. On the one hand, cancer is a manifestation of malfunctions in immunity, as malignant cells manage to escape recognition and elimination by the immune system. Chronic infections and inflammation associated with limited or polarized immune responses also contribute to carcinogenesis and tumor progression. The tumor immunoenvironment represents specific conditions and elements that support cancerous cell survival, proliferation and spreading. On the other hand, the specificity and strength of antitumor immunity is a powerful and efficient tool that can be used to recognize and destroy neoplastic cells or their supporting microenvironment. Understanding the role of the immune system in controlling and supporting tumor initiation, formation, growth and progression has crucial implications for cancer therapy and will therefore guide the future development of cancer immunotherapy and its combination with conventional therapies to achieve optimal antitumor effects in patients with different types of cancer.Keywords: tumor immunology and immunotherapy, tumor immunoenvironment, cancer, immunosuppression

In this study, we aim to determine the accuracy of CT/PET as a tool for identifying such metastases. Methods: All patients from Royal Prince Alfred and Liverpool Hospitals, who underwent CT/PET for any cancer arising from the head and neck, and who underwent subsequent surgery (which included a neck dissection) within 8 weeks of the CT/PET were included. Nodal staging was undertaken by utilising imaging-based nodal classification, and comparison with pathologic data from the surgical specimen was made. PET was considered positive if the SUV was greater than 2. Results: We identified 111 patients from the above criteria. 80 of such patients were treated for squamous cell carcinoma (SCC). CT/PET identified unsuspected metastatic disease in 6 patients. Correlation of CT/PET findings and the presence of disease at the primary site: sensitivity: 98%, specificity: 93%, positive predictive value (PPV): 98% and negative predictive value (NPV): 93%. Correlating CT/PET findings with the presence of nodal disease at any level: sensitivity: 95%, specificity: 88%, PPV: 95% and NPV: 88%. CT/PET was anatomically accurate in predicting the site of metastases in 62/74 (84%). Conclusion: PET is accurate in predicting both presence of nodal metastases and the level of involvement. CT/PET should be undertaken as a pre-operative tool to assist in planning the extent of surgery required in head and neck cancers.

Determine workplace productivity losses attributable to breast cancer progression. Longitudinal analysis linking 2005 to 2012 medical and pharmacy claims and workplace absence data in the US patients were commercially insured women aged 18 to 64 diagnosed with breast cancer. Productivity was measured as employment status and total quarterly workplace hours missed, and valued using average US wages. Six thousand four hundred and nine women were included. Breast cancer progression was associated with a lower probability of employment (hazard ratio [HR] = 0.65, P work was $24,166 for non-metastatic and $30,666 for metastatic patients. Thus, progression to metastatic disease is associated with an additional $6500 in lost work time (P < 0.05), or 14% of average US wages. Breast cancer progression leads to diminished likelihood of employment, increased workplace hours missed, and increased cost burden.

Serum pepsinogens I and II (PGI, PGII) levels were determined by PGI and PGII-RIA kits in 84 healthy controls and 128 patients of gastric diseases including 42 patients with gastric cancer. The results showed peptic ulcer cases had elevated PGI and PGII levels. The atrophic gastritis cases had low PGI levels and the gastric cancer cases had low PGI and low PGI/PGII ratio. Using the cut-off values of PGI<35 μg/L and PGI/PGII<1.5 for clinical purpose, the sensitivity and specificity of the test for gastric cancer was 73% and 78%, respectively. Combined with endoscope examination, the serum PGI and PGII levels are valuable for the early diagnosis of gastric cancer

Full Text Available The identification of biologically significant variants in cancer genomes is critical to therapeutic discovery, but it is limited by the statistical power needed to discern driver from passenger. Independent biological data can be used to filter cancer exomes and increase statistical power. Large genetic databases for inherited diseases are uniquely suited to this task because they contain specific amino acid alterations with known pathogenicity and molecular mechanisms. However, no rigorous method to overlay this information onto the cancer exome exists. Here, we present a computational methodology that overlays any variant database onto the somatic mutations in all cancer exomes. We validate the computation experimentally and identify novel associations in a re-analysis of 7362 cancer exomes. This analysis identified activating SOS1 mutations associated with Noonan syndrome as significantly altered in melanoma and the first kinase-activating mutations in ACVR1 associated with adult tumors. Beyond a filter, significant variants found in both rare cancers and rare inherited diseases increase the unmet medical need for therapeutics that target these variants and may bootstrap drug discovery efforts in orphan indications.

Full Text Available Non-alcoholic fatty liver disease (NAFLD is a leading cause of chronic liver disease but the second cause of death among NAFLD patients are attributed to malignancies at both gastrointestinal (liver, colon, esophagus, stomach, and pancreas and extra-intestinal sites (kidney in men, and breast in women. Obesity and related metabolic abnormalities are associated with increased incidence or mortality for a number of cancers. NAFLD has an intertwined relationship with metabolic syndrome and significantly contributes to the risk of hepatocellular carcinoma (HCC, but recent evidence have fuelled concerns that NAFLD may be a new, and added, risk factor for extra-hepatic cancers, particularly in the gastrointestinal tract. In this review we critically appraise key studies on NAFLD-associated extra-hepatic cancers and speculate on how NAFLD may influence carcinogenesis at these sites.

IgG4-related disease (IgG4-RD) is a systemic disease that affects multiple organs and generates nodules or thickening. Discriminating these diseases from malignancy is important because glucocorticoid treatment is effective for patients with IgG4-RD. Coexistence of IgG4-RD with various malignant diseases has been reported, but there are few reports with regard to gynecologic malignant diseases. We encountered a case of invasive cervical cancer stage IIB accompanied by IgG4-RD. The patient was a 46-year-old woman. On pelvic magnetic resonance imaging, fluorodeoxyglucose-positron emission tomography and computed tomography, systemic multiple lymph node swelling was seen, including in the neck and the mediastinum in addition to uterine cervix. Diagnosis (and hence, appropriate treatment choice) was achieved on pathology of the submandibular gland and uterus, and analysis of serum IgG4. IgG4-RD should be suspected in patients presenting with malignancy and unusual multiple lymph node swelling. © 2016 Japan Society of Obstetrics and Gynecology.

Papanicolaou Hospital, Thessaloniki, Greece Abstract: Chronic obstructive pulmonary disease (COPD and lung cancer share a common etiological factor (cigarette smoking and usually coexist in everyday clinical practice. The prevalence of COPD among newly diagnosed patients with lung cancer sometimes exceeds 50%. COPD is an independent risk factor (2–4 times higher than non-COPD subjects for lung cancer development.The presence of emphysema in addition to other factors (e.g., smoking history, age could be incorporated into risk scores in order to define the most appropriate target group for lung cancer screening using low-dose computed tomography. Clinical management of patients with coexistence of COPD and lung cancer requires a multidisciplinary oncology board that includes a pulmonologist. Detailed evaluation (lung function tests, cardiopulmonary exercise test and management (inhaled drugs, smoking cessation, pulmonary rehabilitation of COPD should be taken into account for lung cancer treatment (surgical approach, radiotherapy.

Brody, R.S.; Schottenfeld, D.; Reid, A.

1977-01-01

Forty-four antecedent, synchronous, and metachronous multiple primary cancers were identified among 41 patients who constituted 4.0% of 1028 patients initially treated for Hodgkin's disease during the years 1950--1954, 1960--1964, and 1968--1972. At 5 years post-therapy the cumulative probabilities of developing a multiple primary cancer for patients treated in 1950--1954, 1960--1964, and 1968--1972, were 1.14%, 1.48%, and 4.43%, respectively. At 10 years the cumulative probability of a multiple primary cancer was 2.54% for the 1950--1954 treatment group and 6.52% for the 1960--1964 treatment group. Among those patients 16-39 years of age, initially treated during the period 1960--1964, who had survived 6-10 years after receiving radiation plus single agent chemotherapy, we observed a significant 18-fold increase in the number of multiple primary cancers. A significant occurrence of two multiple primary cancers in a relatively small group of patients treated with chemotherapy only during the period 1968--1972 was also noted. Continued surveillance of patients extensively treated with combination chemotherapy and radiotherapy will enable assessment of the oncogenic potential of these modern therapeutic approaches to the management of Hodgkin's disease

Improved cancer survivorship has resulted in a growing number of Canadians affected by cancer and cardiovascular disease. As a consequence, cardio-oncology programs are rapidly emerging to treat cancer patients with de novo and preexisting cardiovascular disease. The primary goal of a cardio-oncology program is to preserve cardiovascular health to allow the timely delivery of cancer therapy and achieve disease-free remission. Multidisciplinary programs in oncology and cardiology have been associated with enhanced patient well-being and improved clinical outcomes. Because of the complex needs of these multisystem patients, a similar model of care is gaining acceptance. The optimal composition of the cardio-oncology team will typically involve support from cardiology, oncology, and nursing. Depending on the clinical scenario, additional consultation from dietetics, pharmacy, and social services might be required. Timely access to consultation and testing is another prerequisite for cardio-oncology programs because delays in treating cardiac complications and nonadherence to prescribed cancer therapy are each associated with poor outcomes. Recommended reasons for referral to cardio-oncology programs include primary prevention for those at high risk for cardiotoxicity and the secondary treatment of new or worsening cardiovascular disease in cancer patients and survivors. Management is multifaceted and can involve lifestyle education, pharmacotherapy, enhanced cardiovascular surveillance, and support services, such as exercise training. The lack of evidence to guide clinical decisions and recommendations in cardio-oncology is a major challenge and opportunity for health care professionals. Large multicentre prospective registries are needed to adequately power risk model calculations and generate hypotheses for novel interventions. Copyright © 2016 Canadian Cardiovascular Society.

Early detection and efficient treatment of cancer disease remains a drastic challenge in 21st century. Throughout the bulk of funds, studies, and current therapeutics, cancer seems to aggressively advance with drug resistance strains and recurrence rates. Nevertheless, nanotechnologies have indeed given hope to be the next generation for oncology applications. According to US National cancer institute, it is anticipated to revolutionize the perspectives of cancer diagnosis and therapy. With such success, nano-hybrid strategy creates a marvelous preference. Herein, graphene-gold based composites are being increasingly studied in the field of oncology, for their outstanding performance as robust vehicle of therapeutic agents, built-in optical diagnostic features, and functionality as theranostic system. Additional modes of treatments are also applicable including photothermal, photodynamic, as well as combined therapy. This review aims to demonstrate the various cancer-related applications of graphene-gold based hybrids in terms of detection and therapy, highlighting the major attributes that led to designate such system as a promising ally in the war against cancer.

Exosomes in Cancer Disease.

Science.gov (United States)

Zöller, Margot

2016-01-01

Cancer diagnosis and therapy is steadily improving. Still, diagnosis is frequently late and diagnosis and follow-up procedures mostly are time-consuming and expensive. Searching for tumor-derived exosomes (TEX) in body fluids may provide an alternative, minimally invasive, yet highly reliable diagnostic tool. Beyond this, there is strong evidence that TEX could become a potent therapeutics. Exosomes, small vesicles delivered by many cells of the organism, are found in all body fluids. Exosomes are characterized by lipid composition, common and donor cell specific proteins, mRNA, small non-coding RNA including miRNA and DNA. Particularly the protein and miRNA markers received much attention as they may allow for highly specific diagnosis and can provide hints toward tumor aggressiveness and progression, where exosome-based diagnosis and follow-up is greatly facilitated by the recovery of exosomes in body fluids, particularly the peripheral blood. Beyond this, exosomes are the most important intercellular communicators that modulate, instruct, and reprogram their surrounding as well as distant organs. In concern about TEX this includes message transfer from tumor cells toward the tumor stroma, the premetastatic niche, the hematopoietic system and, last but not least, the instruction of non-cancer stem cells by cancer-initiating cells (CIC). Taking this into account, it becomes obvious that "tailored" exosomes offer themselves as potent therapeutic delivery system. In brief, during the last 4-5 years there is an ever-increasing, overwhelming interest in exosome research. This boom appears fully justified provided the content of the exosomes becomes most thoroughly analyzed and their mode of intercellular interaction can be unraveled in detail as this knowledge will open new doors toward cancer diagnosis and therapy including immunotherapy and CIC reprogramming.

Since ancient times, people have attributed a variety of health benefits to moderate consumption of fermented beverages such as wine and beer, often without any scientific basis. There is evidence that excessive or binge alcohol consumption is associated with increased morbidity and mortality, as well as with work related and traffic accidents. On the contrary, at the moment, several epidemiological studies have suggested that moderate consumption of alcohol reduces overall mortality, mainly from coronary diseases. However, there are discrepancies regarding the specific effects of different types of beverages (wine, beer and spirits) on the cardiovascular system and cancer, and also whether the possible protective effects of alcoholic beverages are due to their alcoholic content (ethanol) or to their non-alcoholic components (mainly polyphenols). Epidemiological and clinical studies have pointed out that regular and moderate wine consumption (one to two glasses a day) is associated with decreased incidence of cardiovascular disease (CVD), hypertension, diabetes, and certain types of cancer, including colon, basal cell, ovarian, and prostate carcinoma. Moderate beer consumption has also been associated with these effects, but to a lesser degree, probably because of beer’s lower phenolic content. These health benefits have mainly been attributed to an increase in antioxidant capacity, changes in lipid profiles, and the anti-inflammatory effects produced by these alcoholic beverages. This review summarizes the main protective effects on the cardiovascular system and cancer resulting from moderate wine and beer intake due mainly to their common components, alcohol and polyphenols.

Usefulness of FDG PET CT in monitoring response in locally advanced gastric cancer has been reported. The purpose of this study was to evaluate the related factors to detect measurable diseases in advanced gastric cancer on FDG PET CT. We retrospectively reviewed 38 patients diagnosed as having advanced gastric cancer. We defined the measurable diseases when there was visualized tumor of which maximum standardized uptake value(SUVmax) was higher than 1.35*SUVmax of liver + 2*SD of liver SUV. We evaluated what kinds of factors from the clinicopathologic features were related to identifying measurable diseases. Of 38 patients with advanced gastric cancer, 18 (50%) had measurable tumors on FDG PET CT. Measurable tumors were significantly more frequent in well or moderately differentiated adenocarcinoma (70.5% vs 35.3%, p<0.05), in the tumors located at antrum or angle (66.7% vs 29.4%, p<0.05) and in the elderly group (age of 55 years old or more, 72.0% vs 8.3%, p<0.001) than the others, respectively. By multivariate analysis, age at diagnosis was the only independent predictor for the measurable disease on FDG PET CT. We found that age at diagnosis, as well as histologic types and location of tumors, were the affecting factors to detect measurable disease on FDG PET CT in patients with advanced gastric cancer. Our study suggests that elderly patients of age of 55 years old or more can frequently have T measurable disease on FDG PET CT in advanced gastric cancer and FDG PET CT will be helpful to monitor measurable disease

To assess the relationship between platelet counts and risk of AIDS and non-AIDS-defining events. Prospective cohort. EuroSIDA patients with at least one platelet count were followed from baseline (first platelet ≥ 1 January 2005) until last visit or death. Multivariate Poisson regression was used to assess the relationship between current platelet counts and the incidence of non-AIDS-defining (pancreatitis, end-stage liver/renal disease, cancer, cardiovascular disease) and AIDS-defining events. There were 62 898 person-years of follow-up (PYFU) among 12 279 patients, including 1168 non-AIDS-defining events [crude incidence 18.6/1000 PYFU, 95% confidence interval (CI) 17.5-19.6] and 735 AIDS-defining events (crude incidence 11.7/1000 PYFU, 95% CI 10.8-12.5). Patients with thrombocytopenia (platelet count ≤100 × 10/l) had a slightly increased incidence of AIDS-defining events [adjusted incidence rate ratio (aIRR) 1.42, 95% CI 1.07-1.86], when compared to those with platelet counts 101-200 × 10/l, whereas the incidence of non-AIDS-defining events was more than two-fold higher (aIRR 2.66, 95% CI 2.17-3.26). Among non-AIDS-defining events, the adjusted incidence of cancer (aIRR 2.20, 95% CI 1.61-3.01), but not cardiovascular disease (aIRR 0.66, 95% CI 0.32-1.34), was significantly higher in patients with thrombocytopenia. The association between thrombocytopenia and cancer remained unaltered in sensitivity analyses requiring repeated platelet counts to confirm thrombocytopenia and lagging platelets by 1 year prior to clinical events. Patients with thrombocytopenia had increased incidence of AIDS-defining and non-AIDS-defining events, but the association with the latter, in particular cancer, was stronger. Future studies should investigate whether the pathophysiological processes underlying thrombocytopenia are associated with the development of cancer during treated HIV disease.

It is well established that moderate to high doses of radiation can increase the occurrence also of a variety of non-cancer effects in exposed individuals, but for radiation protection purposes it has generally been assumed that there is a threshold of dose below which no significant non-cancer effects (apart from hereditary disease) arise. In recent years, there is growing epidemiological evidence of excess risk of late occurring cardiovascular disease at much lower radiation doses and occurring over much longer intervals after radiation exposure without a clear cut threshold. However, the epidemiological evidence available so far for non-cancer health effects after exposure to moderate or low radiation doses is suggestive rather than persuasive. The mechanisms of radiation-induced vascular disease induction are far away from being understood. However, it seems to be very likely that inflammatory responses are involved. Recent experimental studies by Stewart et al. could demonstrate that high dose exposure to the cardiovascular system is associated with an earlier onset and accelerated development of macrophage-rich, inflammatory atherosclerotic lesions prone to intra-plaque hemorrhage and may also cause a decrease in myocardial perfusion. Both, macro-vascular and micro-vascular radiation effects involve the endothelium and pro-inflammatory signalling cascades. If modulation of inflammatory response is arguably also the most likely cause of radiation-induced cardiovascular disease after low dose exposure, this also implies a role for non-targeted radiation effects. In the absence of a convincing mechanistic explanation of the currently available epidemiological evidence for radiation-induced cardiovascular risk at low radiation doses, caution is required in the interpretation of the statistical associations. On the other hand, the possibility of such a causal explanation cannot be reliably excluded. Further epidemiological and biological evidence from currently

Due to high recurrence rates, intensive surveillance strategies, and expensive treatment costs, the management of bladder cancer contributes significantly to medical costs. To provide a concise evaluation of contemporary cost-related challenges in the care of patients with bladder cancer. An emphasis is placed on the initial diagnosis of bladder cancer and therapy considerations for both non-muscle-invasive bladder cancer (NMIBC) and more advanced disease. A systematic review of the literature was performed using Medline (1966 to February 2011). Medical Subject Headings (MeSH) terms for search criteria included "bladder cancer, neoplasms" OR "carcinoma, transitional cell" AND all cost-related MeSH search terms. Studies evaluating the costs associated with of various diagnostic or treatment approaches were reviewed. Routine use of perioperative chemotherapy following complete transurethral resection of bladder tumor has been estimated to provide a cost savings. Routine office-based fulguration of small low-grade recurrences could decrease costs. Another potential important target for decreasing variation and cost lies in risk-modified surveillance strategies after initial bladder tumor removal to reduce the cost associated with frequent cystoscopic and radiographic procedures. Optimizing postoperative care after radical cystectomy has the potential to decrease length of stay and perioperative morbidity with substantial decreases in perioperative care expenses. The gemcitabine-cisplatin regimen has been estimated to result in a modest increase in cost effectiveness over methotrexate, vinblastine, doxorubicin, and cisplatin. Additional costs of therapies need to be balanced with effectiveness, and there are significant gaps in knowledge regarding optimal surveillance and treatment of both early and advanced bladder cancer. Regardless of disease severity, improvements in the efficiency of bladder cancer care to limit unnecessary interventions and optimize effective

How are cancer and connective tissue diseases related to sarcoidosis?

Chopra, Amit; Judson, Marc A

2015-09-01

Several studies have suggested an association between sarcoidosis and cancer, and between sarcoidosis and connective tissue diseases (CTDs). In this review, we discuss the evidence supporting and refuting these associations. In terms of a cancer risk in sarcoidosis patients, the data are somewhat conflicting but generally show a very small increased risk. The data supporting an association between sarcoidosis and CTD are not as robust as for cancer. However, it appears that scleroderma is the CTD most strongly associated with sarcoidosis. There are several important clinical and research-related implications of the association of sarcoidosis and CTDs. First, rigorous efforts should be made to exclude alternative causes for granulomatous inflammation before establishing a diagnosis of sarcoidosis. Second, the association between sarcoidosis and both cancer and CTDs may yield important insights into the immunopathogenesis of all three diseases. Finally, these data provide insight in answering a common question asked by sarcoidosis patients, 'Am I at an increased risk of developing cancer?' We believe that although there is an increased (relative) risk of cancer in sarcoidosis patients compared with the general population, that increased risk is quite small (low absolute risk).

Cell secreted exosomes (30-100nm vesicles) play a major role in intercellular communication due to their ability to transfer proteins and nucleic acids from one cell to another. Depending on the originating cell type and the cargo, exosomes can have immunosuppressive or immunostimulatory effects, which have potential application as immunotherapies for cancer and autoimmune diseases. Cellular components shed from tumor cells or antigen presenting cells (APCs), such as dendritic cells, macrophages and B cells, have been shown to be efficiently packaged in exosomes. In this review, we focus on the application of exosomes as nanocarriers and immunological agents for cancer and autoimmune immunotherapy. APC-derived exosomes demonstrate effective therapeutic efficacy for the treatment of cancer and experimental autoimmune diseases such as rheumatoid arthritis, inflammatory bowel disease, and multiple sclerosis. In addition to their intrinsic immunomodulating activity, exosomes have many advantages over conventional nanocarriers for drug and gene delivery. Copyright © 2015 Elsevier Inc. All rights reserved.

Dermatologic manifestations of inflammatory bowel disease (IBD) are common, and certain IBD medications increase the risk of skin cancer. To define the rates of care and factors associated with dermatologic utilization with a focus on skin cancer screening. We utilized a prospective, natural history IBD research registry to evaluate all outpatient healthcare encounters from 2010 to 2016. Gastrointestinal, dermatologic and primary care visits per individual were identified. We calculated the proportion of patients obtaining care, categorized primary indications for dermatologic visits, determined the incidence of melanoma and non-melanoma skin cancers, and used logistic regression to determine factors associated with dermatology utilization. Of the 2127 IBD patients included, 452 (21.3%) utilized dermatology over the study period, and 55 (2.6%) had a total body skin examination at least once. The 452 patients incurred 1633 dermatology clinic visits, 278 dermatologic procedures, and 1108 dermatology telephone encounters. The most frequent indication was contact dermatitis or dermatitis. Factors associated with dermatology use were family history of skin cancer, employment, systemic steroids, longer disease duration, emergency room use, and the number of IBD-related clinic visits. Between 8.3 and 11% of IBD patients recommended for skin cancer screening visited dermatology each year, and the resulting incidence of non-melanoma skin cancer was 35.4/10,000 [95% CI 23.3-51.5] and melanoma was 6.56/10,000 [95% CI 2.1-15.3]. Less than one in ten IBD patients obtain dermatologic care. Given the increased risk of skin cancers among IBD patients, an emphasis on education, prevention, and screening merits attention.

Full Text Available BACKGROUND: SPARC is a matricellular protein involved in tissue remodelling, cell migration and angiogenesis, while forkhead box P3 (FOXP3 protein functions as a transcription factor involved in immune cell regulation. Both SPARC and FOXP3 can play an anti-tumorigenic role in cancer progression. The aim was to determine if SPARC, FOXP3, CD8 and CD45RO expression levels are associated with colorectal cancer (CRC stage, disease outcome and long-term cancer-specific survival (CSS in stage II and III CRC. METHODS AND FINDINGS: SPARC expression was initially assessed in 120 paired normal and stage I-IV CRCs. Subsequently, approximately 1000 paired patient samples of stage II or III CRCs in tissue microarrays were stained for SPARC, FOXP3, CD8 or CD45RO. Proportional hazards modelling assessed correlations between these markers and clinicopathological data, including disease outcome and cancer specific survival (CSS. Both SPARC and FOXP3 expression were significantly greater in CRC than normal colon (p<0.0001. High SPARC expression correlated with good disease outcome (≥60 mths without disease recurrence, p = 0.0039 and better long-term CSS in stage II CRC (<0.0001. In stage III CRC, high SPARC expression correlated with better long-term CSS (p<0.0001 and less adjuvant chemotherapy use (p = 0.01. High FOXP3 correlated with a good disease outcome, better long-term CSS and less adjuvant chemotherapy use in stage II (p<0.0037, <0.0001 and p = 0.04 respectively, but not in stage III CRC. High CD8 and CD45RO expression correlated with better disease outcome in stage II CRC, and better CSS, but the differences were not as marked as for SPARC and FOXP3. CONCLUSIONS: These data suggest that high SPARC and FOXP3 are associated with better disease outcome in stage II CRC and may be prognostic indicators of CSS. Further assessment of whether these markers predict patients at high risk of recurrence with stage II CRC and functional studies of these

PURPOSES/OBJECTIVE: There exists little information concerning the natural history of rectal cancer in patients with inflammatory bowel disease. In addition, the tolerance of pelvic irradiation in these patients is unknown. We analyzed the largest series of patients with inflammatory bowel disease and rectal cancer in order to determine the natural history of the disease as well as the effect and tolerance of pelvic irradiation. MATERIAL AND METHODS: A retrospective analysis of 47 patients with inflammatory bowel disease and rectal cancer treated over a 34 year period (1960-1994) was performed. Thirty five patients had Ulcerative Colitis and 12 patients had Crohn's Disease. There were 31 male patients and 16 female patients. The stage (AJC) distribution was as follows: stage 0 in 5 patients, stage I in 13 patients, stage II in 7 patients, stage III in 13 patients and stage IV in 9 patients. Surgical resection was performed in 44 patients. In 2 of these patients, preoperative pelvic irradiation was given followed by surgery. Twenty of these patients underwent post-operative adjuvant therapy (12 were treated with chemotherapy and pelvic irradiation and 8 with chemotherapy alone). Three patients were found to have unresectable disease and were treated with chemotherapy alone (2 patients) or chemotherapy and radiation therapy (1 patient). Radiation complications were graded using the RTOG acute and late effects scoring criteria. Follow up ranged from 4 to 250 months (median - 24 months). RESULTS: The 5 year actuarial results revealed an overall survival (OS) of 42%, a disease free survival (DFS) of 43%, a pelvic control rate (PC) of 67% and a freedom from distant failure (FFDF) of 47%. DFS decreased with increasing T stage with a 5 year rate of 86% for patients with Tis - T2 disease compared to 10% for patients with T3-T4 disease (p ) were noted in 3 patients (20%) receiving radiation therapy and these included two cases of grade 3 skin reactions and one case of grade

Background: Recent data suggest that neuroendocrine signaling pathways may play a role in the progression of prostate cancer, particularly for early-stage disease. We aimed to explore whether expression of selected genes in the adrenergic, serotoninergic, glucocorticoid, and dopaminergic pathways differs in prostate tumor tissue from men with lethal disease compared with men with nonlethal disease. Methods: On the basis of the Swedish Watchful Waiting Cohort, we included 511 men diagnosed with incidental prostate cancer through transurethral resection of the prostate during 1977-1998 with follow-up up to 30 years. For those with tumor tissue ( N = 262), we measured mRNA expression of 223 selected genes included in neuroendocrine pathways. Using DNA from normal prostate tissue ( N = 396), we genotyped 36 SNPs from 14 receptor genes. Lethal prostate cancer was the primary outcome in analyses with pathway gene expression and genetic variants. Results: Differential expression of genes in the serotoninergic pathway was associated with risk of lethal prostate cancer ( P = 0.007); similar but weaker associations were noted for the adrenergic ( P = 0.014) and glucocorticoid ( P = 0.020) pathways. Variants of the HTR2A (rs2296972; P = 0.002) and NR3CI (rs33388; P = 0.035) genes (within the serotoninergic and glucocorticoid pathways) were associated with lethal cancer in overdominant models. These genetic variants were correlated with expression of several genes in corresponding pathways ( P pathways, particularly serotoninergic pathway, are associated with lethal outcome in the natural course of localized prostate cancer. Impact: This study provides evidence of the role of neuroendocrine pathways in prostate cancer progression that may have clinical utility.

Full Text Available The purpose of the study is to develop an effective radiological symptom-complex of small-sized breast cancer affected by fibrocystic breast disease by using multivariate statistical methods.Materials and methods. Radiological findings of small-sized breast cancer affected by fibrocystic mastopathy were analyzed in 100 patients with histologically verified diagnosis.Results. It was revealed that the conventional approach to the analysis of mammograms based on the detection of the primary, secondary and indirect mammographic signs of small-sized breast cancer is not effective enough - the sensitivity of mammography is only 62%. Fibrocystic disease and moderate-to-severe sclerosing adenosis make small-sized breast cancer hard to visualize by mammography. The detailed analysis of mammograms allowed us to identify the additional manifestations of small-sized breast cancer affected by mastopathy. The computer program allowing us to evaluate the risk of small-size breast cancer and the diagnostic algorithm for detecting small size breast cancer with sensitivity of 92% were developed.

Nutrition has a profound effect on chronic liver disease, especially non-alcoholic fatty liver disease (NAFLD). Most observational studies and clinical trials have focussed on the effects of total energy intake, or the intake of individual macronutrients and certain micronutrients, such as vitamin D, on liver disease. Although these studies have shown the importance of nutrition on hepatic outcomes, there is not yet any unifying framework for understanding the relationship between diet and liver disease. The Geometric Framework for Nutrition (GFN) is an innovative model for designing nutritional experiments or interpreting nutritional data that can determine the effects of nutrients and their interactions on animal behaviour and phenotypes. Recently the GFN has provided insights into the relationship between dietary energy and macronutrients on obesity and ageing in mammals including humans. Mouse studies using the GFN have disentangled the effects of macronutrients on fatty liver and the gut microbiome. The GFN is likely to play a significant role in disentangling the effects of nutrients on liver disease, especially NAFLD, in humans. Copyright © 2017 European Association for the Study of the Liver.

Much is still unknown about the health effects of low-level radiation on human health, particularly on the risk of non-cancer diseases. A review by Radiation Effects Research Foundation (RERF) scientists has concluded that the association of atomic-bomb radiation and cardiovascular disease (CVD) is almost certain since the relationship was shown by incidence and prevalence studies of various endpoints of atherosclerosis. In addition to the studies of atomic bomb survivors, the association of CVD with radiation exposure was observed in several other studies, including the follow-up study of patients treated for Hodgkin lymphoma, ankylosing spondilitis, peptic ulcer and scoliosis as well as nuclear workers. The inhabitants in the high background radiation area (HBRA) of Yangjiang, Guangdong Province, China receive the external radiation doses of 1.33 mSv in excess every year, mainly from exposure to terrestrial gamma ray, when compared to the residents in the neighboring control area (CA). Our most recent analysis of cancer mortality among residents in the HBRA and the CA showed no evident difference between the two areas. It should be of note that the crude cancer mortality rate in the study population was 60/100,000 person-years, which is much lower than cancer mortality in developed countries. On the other hand, non cancer deaths accounted for 90% of all deaths. In this report, we present the results of mortality analysis for non-cancer diseases during the period 1979-1998. (author)

Regional and epidemiological cancer registries are important for cancer research and the quality management of cancer treatment. Many technological solutions are available to collect and analyse data for cancer registries nowadays. However, the lack of a well-defined common semantic model is a problem when user-defined analyses and data linking to external resources are required. The objectives of this study are: (1) design of a semantic model for local cancer registries; (2) development of a semantically-enabled cancer registry based on this model; and (3) semantic exploitation of the cancer registry for analysing and visualising disease courses. Our proposal is based on our previous results and experience working with semantic technologies. Data stored in a cancer registry database were transformed into RDF employing a process driven by OWL ontologies. The semantic representation of the data was then processed to extract semantic patient profiles, which were exploited by means of SPARQL queries to identify groups of similar patients and to analyse the disease timelines of patients. Based on the requirements analysis, we have produced a draft of an ontology that models the semantics of a local cancer registry in a pragmatic extensible way. We have implemented a Semantic Web platform that allows transforming and storing data from cancer registries in RDF. This platform also permits users to formulate incremental user-defined queries through a graphical user interface. The query results can be displayed in several customisable ways. The complex disease timelines of individual patients can be clearly represented. Different events, e.g. different therapies and disease courses, are presented according to their temporal and causal relations. The presented platform is an example of the parallel development of ontologies and applications that take advantage of semantic web technologies in the medical field. The semantic structure of the representation renders it easy to

Wine, Beer, Alcohol and Polyphenols on Cardiovascular Disease and Cancer

Directory of Open Access Journals (Sweden)

Full Text Available Since ancient times, people have attributed a variety of health benefits to moderate consumption of fermented beverages such as wine and beer, often without any scientific basis. There is evidence that excessive or binge alcohol consumption is associated with increased morbidity and mortality, as well as with work related and traffic accidents. On the contrary, at the moment, several epidemiological studies have suggested that moderate consumption of alcohol reduces overall mortality, mainly from coronary diseases. However, there are discrepancies regarding the specific effects of different types of beverages (wine, beer and spirits on the cardiovascular system and cancer, and also whether the possible protective effects of alcoholic beverages are due to their alcoholic content (ethanol or to their non-alcoholic components (mainly polyphenols. Epidemiological and clinical studies have pointed out that regular and moderate wine consumption (one to two glasses a day is associated with decreased incidence of cardiovascular disease (CVD, hypertension, diabetes, and certain types of cancer, including colon, basal cell, ovarian, and prostate carcinoma. Moderate beer consumption has also been associated with these effects, but to a lesser degree, probably because of beer’s lower phenolic content. These health benefits have mainly been attributed to an increase in antioxidant capacity, changes in lipid profiles, and the anti-inflammatory effects produced by these alcoholic beverages. This review summarizes the main protective effects on the cardiovascular system and cancer resulting from moderate wine and beer intake due mainly to their common components, alcohol and polyphenols.

Tumor-Protective Mechanism Identified from Premature Aging Disease | Center for Cancer Research

Science.gov (United States)

Hutchinson-Gilford Progeria Syndrome (HGPS) is an extraordinarily rare genetic disorder caused by a mutation in the LMNA gene, which encodes architectural proteins of the human cell nucleus. The mutation causes the production of a mutant protein called progerin. Patients with HGPS display signs of premature aging, such as hair loss, slowed growth, weakening of bone and joint integrity, and cardiovascular disease. Most die in their mid-teens of heart disease or stroke. Intriguingly, these patients do not develop another aging-related disease, cancer, despite having dramatically elevated levels of DNA damage. Tom Misteli, Ph.D., of CCR’s Laboratory of Receptor Biology and Gene Expression, and his colleagues hypothesized that, rather than patients not living long enough to develop cancer, a resistance mechanism was operating in HGPS cells to prevent cancer formation. To begin testing this idea, the researchers transformed fibroblasts from HGPS patients or age-matched, healthy controls with telomerase, constitutively-activated HRAS, and SV40 large and small T antigens. Transformed HGPS cells displayed morphological changes and increased proliferation similar to transformed controls but formed fewer colonies in soft agar and fewer tumors when injected into mice. When the investigators examined global gene expression in the two populations of cells, they found that transformed HGPS cells failed to activate many of the genes that are induced in response to transformation in controls, including oncogenic and proliferation pathways. In addition the transformed HGPS cells were unable to undergo oncogenic de-differentiation. Importantly, the tumor resistance in HGPS cells was due to the presence of the progerin protein, which was both necessary and sufficient to protect cells from oncogenic transformation. Together these results suggested that HGPS cells resist cancer-inducing stimuli by not undergoing the genetic reprogramming necessary for tumor initiation. The scientists

1989-01-01

This work is based on the retrospective study of the case history of 26 patients who were treated between September 1979 and January 1987 in the department of thoracic and vascular surgery at the Avicenne Hospital--and who were all suffering from both lung cancer and atheromatous arterial disease. It is now well established by all the epidemiologic research that the link between lung cancer and atheromatous arterial disease is smoking tobacco. The risks involved in the misunderstanding of such an association are not without danger for the patient, particularly the risk of severe complication of possible coronary or carotid lesions, threatening survival; from this derives the necessity to decide automatically for a minimum of pre-surgery vascular investigations in the case of patients suffering from lung cancer. The therapeutic strategy in this association must be thorough, considering that there are three priorities in the vascular field which must absolutely be treated before the lung itself: --the coronary and carotid lesions which are likely to be complicated cancer after surgery and any state of emergency in the other vascular territories. The fight against tobacco smoking must also be considered as a priority aim.

Alhanafy, Alshimaa Mahmoud; Zanaty, Fouad; Ibrahem, Reda; Omar, Suzan

2018-04-27

Background and Aim: The optimal management of metastatic hormone-sensitive prostate cancer has been controversial in recent years with introduction of upfront chemohormonal treatment based on results of several Western studies. This changing landscape has renewed interest in the concept “disease volume”, the focus of the present study is the Egyptian patients. Methods: Patients with hormone sensitive metastatic prostate cancer presenting at Menoufia University Hospital, Egypt, during the period from June 2013 to May 2016, were enrolled. All received hormonal treatment. Radiologic images were evaluated and patients were stratified according to their disease volume into high or low, other clinical and pathological data that could affect survival also being collected and analyzed. Results: A total of 128 patients were included, with a median age of 70 years (53.9% ≥70). About 46% had co-morbidities, 62% having high volume disease. During the median follow up period of 28 months about half of the patients progressed and one third received chemotherapy. On univariate analysis, disease volume, performance status (PS), prostate specific antigen level (PSA) and presence of pain at presentation were identified as factors influencing overall survival. Multivariate analysis revealed the independent predictor factors for survival to be PS, PSA and disease volume. The median overall survival with 27 months was high volume versus 49 with low volume disease (hazard ratio 2.1; 95% CI 1.2 - 4.4; P=0.02). Median progression free survival was 19 months in the high volume, as compared with 48 months in the low volume disease patients (hazard ratio, 2.44; 95% CI, 1.42 – 7.4; P=0.009). Conclusions: Disease volume is a reliable predictor of survival which should be incorporated with other important factors as; patient performance status and comorbidities in treatment decision-making.

Wang, Mingjun; Yin, Bingnan; Wang, Helen Y; Wang, Rong-Fu

2015-01-01

Cancer is a leading cause of death worldwide; due to the lack of ideal cancer biomarkers for early detection or diagnosis, most patients present with late-stage disease at the time of diagnosis, thus limiting the potential for successful treatment. Traditional cancer treatments, including surgery, chemotherapy and radiation therapy, have demonstrated very limited efficacy for patients with late-stage disease. Therefore, innovative and effective cancer treatments are urgently needed for cancer patients with late-stage and refractory disease. Cancer immunotherapy, particularly adoptive cell transfer, has shown great promise in the treatment of patients with late-stage disease, including those who are refractory to standard therapies. In this review, we will highlight recent advances and discuss future directions in adoptive cell transfer based cancer immunotherapy. PMID:25524383

Data from the German uranium miners cohort study were analyzed to investigate the radon-related risk of mortality from cancer and cardiovascular diseases. The Wismut cohort includes 58,987 men who were employed for at least 6 months from 1946 to 1989 at the former Wismut uranium mining company in Eastern Germany. By the end of 2003, a total of 3,016 lung cancer deaths, 3,355 deaths from extrapulmonary cancers, 5,141 deaths from heart diseases and 1,742 deaths from cerebrovascular diseases were observed. Although a number of studies have already been published on various endpoints in the Wismut cohort, the aim of the present analyses is to provide a direct comparison of the magnitude of radon-related risk for different cancer sites and cardiovascular diseases using the same data set, the same follow-up period and the same statistical methods. A specific focus on a group of cancers of the extrathoracic airways is also made here, due to the assumed high organ doses from absorbed radon progeny. Internal Poisson regression was used to estimate the excess relative risk (ERR) per unit of cumulative exposure to radon in working level months (WLM) and its 95% confidence limits (CI). There was a statistically significant increase in the risk of lung cancer with increasing radon exposure (ERR/WLM = 0.19%; 95% CI: 0.17%; 0.22%). A smaller, but also statistically significant excess was found for cancers of the extrathoracic airways and trachea (ERR/WLM = 0.062%; 95% CI: 0.002%; 0.121%). Most of the remaining nonrespiratory cancer sites showed a positive relationship with increasing radon exposure, which, however, did not reach statistical significance. No increase in risk was noted for coronary heart diseases (ERR/WLM = 0.0003%) and cerebrovascular diseases (ERR/WLM = 0.001%). The present data provide clear evidence of an increased radon-related risk of death from lung cancer, some evidence for an increased radon-related risk of death from cancers of the extrathoracic airways

A total of 91 cases of uterine cervical cancer, consisting of 38 cases of carcinoma in situ (CIN III) and 53 cases of stage I-IV cervical cancer, were retrospectively and clinicopathologically analyzed. The standard treatment given to these patients consisted of hysterectomy or conization for CIN III; observation of cases of mild to moderate dysplasia; radical hysterectomy plus pelvic lymph node dissection for stage I and II cervical cancer; and radiotherapy for stage III and IV cervical cancer. Postoperative irradiation consisted of irradiation of the whole pelvis with 40-50 Gy. The patients who were not treated surgically underwent 40 Gy external irradiation of the whole pelvis, followed by an additional 20 Gy with shielding and internal irradiation with an RALS. When lymph node metastasis was present, the nodes were irradiated with 40-50 Gy. The mean age of the 38 patients with CIN III was 45.2 years old, and they were para 0-4. In 24 (63.2%) of them the cancer was detected by cytodiagnosis as part of screening. Radical hysterectomy, simple hysterectomy, and conization were performed in 25 patients, 7 patients, and 6 patients, respectively. No recurrences have been detected, and the survival rate is 100%. The mean age of the 53 patients with cervical cancer stage I-IV was 62.4 years old, and they were para 0-10. There were 25 patients with stage I disease, 15 patients with stage II disease, 6 patients with stage III, and 7 patients with stage IV, and their 5-year survival rate was 82.4%, 68.8%, 66.7%, and 42.9%, respectively. Radioenteritis and radiocystitis occurred as adverse radiation effects. Pathologic factors influencing lymph node metastasis were examined by a multivariate analysis based on the data from 25 patients with stage I and II who underwent hysterectomy. The results of the analysis indicated the importance of screening and the choice of appropriate surgical method/technique, as well as the need for further investigation to determine the effective

Highlights: • ESUR guideline that abdominal MR sequences are reserved for high-risk prostate cancer is tested. • Routine abdominal sequences are of low yield in prostate cancer MR staging. • Routine abdominal staging sequences frequently result in incidental findings. • Abdominal staging sequences should be reserved for high-risk prostate cancer cases. - Abstract: Objectives: Prostate cancer staging MR examinations commonly include abdominal sequences to assess for non-regional (common iliac or para-aortic) nodal metastasis. In our experience the diagnostic yield of this is limited, but incidental findings are frequent, often necessitating further investigations. The aim of this study is to assess the diagnostic utility of abdominal sequences in routine prostate cancer MR staging studies. Methods: Findings on abdominal sequences of consecutive MRI prostate studies performed for staging newly diagnosed prostate cancer between September 2011 and September 2013 were reviewed with respect to adenopathy and additional incidental findings. Results were correlated with Gleason grade and serum prostate-specific antigen (PSA) level in each case. Results: 355 MRI prostate examinations were reviewed. 4 (1.1%) showed enlarged non-regional lymph nodes. Incidental findings were found in 82(23.1%) cases, neccessitating further investigation in 45 (12.7%) cases. Enlarged non-regional nodes were associated with higher PSA level and Gleason grade (p = 0.007, p = 0.005 respectively). With a combined threshold of PSA > 20 ng/mL and/or Gleason grade ≥8 the sensitivity, specificity, PPV and NPV were 100, 60, 3 and 100% respectively for predicting the presence of non-regional adenopathy. Conclusions: Routine abdominal sequences are of very low yield in routine prostate cancer MR staging, frequently resulting in incidental findings requiring further work-up and should be reserved for high-risk cases. Our experience supports the use of an abdominal staging sequence in high

With the improved prognosis in patients with autosomal dominant polycystic kidney disease (ADPKD), causes of death and the risk of cancer might have changed. This was investigated in a Danish population with ADPKD and end-stage renal disease (ESRD) between 1 January 1993 and 31 December 2008. Data were retrieved from three Danish national registries and a total of 823 patients were identified of which 431 had died during the study period. The 16 years were divided into two 8-year periods and the causes of death were divided into six categories: cancer, cardiovascular, cerebrovascular, infection, other and unknown. Cardiovascular disease was the major cause of death. A multivariate competing risk model comparing the two 8-year periods, adjusted for age at ESRD, gender and treatment modality, showed that deaths from cardiovascular disease decreased by 35% [hazard ratios (HR) 0.65, P=0.008] and deaths from cerebrovascular disease decreased by 69% (HR 0.31, P=0.0003) from the first to the second time period. There were no significant changes between the time periods in death from cancer, infection, other or unknown. From the first to the second 8-year interval, the prevalence of cancer increased by 35% (P=0.0002) while the cancer incidence was stable. In Danish patients with ADPKD and ESRD, there was a significant reduction in cardiovascular and cerebrovascular deaths from 1993 to 2008. The prevalence of cancer increased without significant change in cancer incidence or deaths from cancer.

Cancer risk in inflammatory bowel disease [IBD] is still debated. In a prospective, multicentre, nested case-control study, we aimed to characterise incident cases of cancer in IBD. The role of immunomodulators vs clinical characteristics of IBD as risk factors for cancer was also investigated. From January 2012 to December 2014, each IBD patient with incident cancer was matched with two IBD patients without cancer for: IBD type, gender, and age. Risk factors were assessed by multivariate regression analysis. IBD patients considered numbered 44619: 21953 Crohn's disease [CD], 22666 ulcerative colitis [UC]. Cancer occurred in 174 patients: 99 CD [CD-K], 75 UC [UC-K]. Controls included 198 CD [CD-C], 150 UC [UC-C]. Cancer incidence in IBD was 3.9/1000, higher in CD (4.5/1000 [99/21,953]) than in UC (3.3/1000 [75/22,666]; p = 0.042). Cancers involved: digestive system [36.8%], skin [13.2%], urinary tract [12.1%], lung [8.6%], breast [8%], genital tract [6.9%], thyroid [4.6%], lymphoma [3.5%], others [6.3%]. In CD, penetrating behaviour and combined thiopurines and tumour necrosis factor alpha [TNFα] antagonists were risk factors for cancer overall: odds ratio [OR] (95% confidence interval [CI] 2.33 [1.01-5.47]); 1.97 [1.1-3.5]; and for extracolonic cancers 3.9 [1.56-10.1]; 2.15 [1.17-4.1], respectively. In UC, risk factors were pancolitis and disease-related surgery for cancer overall (OR: 2.52 [1.26-5.1]; 5.09 [1.73-17.1]); disease-related surgery for colorectal cancer [CRC] (OR 3.6 [1.0-12]); and extensive and left-sided vs distal UC for extracolonic cancers (OR: 2.55 [1.15-5.9]; 2.6 [1.04-6.6]), respectively. In a multicentre study, penetrating CD and extensive UC were risk factors for cancer overall. Cancer incidence was higher in CD than in UC.

The report describes the development and summarizes the results of the project Cancer incidence and thyroid disease among Estonian Chernobyl clean-up workers. One of the goals of the report is to give research protocols and questionnaires for researchers involved in other studies. Eight previously published articles are also included summarizing the results. The development of the collaboration work of the project is described in the introduction of the report. Epidemiological methods are described in an article complemented by the protocol and English version of the questionnaire administered to all cleanup workers, as well as the data collection form of the thyroid study. The results from biological biodosimetry using both glycophorin A and FISH methods have shown that the radiation doses received by the Chernobyl cleanup workers were relatively low. Thyroid nodularity was not associated with any radiation exposure characteristic in the thyroid screening study. Estonian Chernobyl cleanup workers were followed up for cancer incidence through the Estonian Cancer Registry. No cases of leukemia or thyroid cancer were observed by the end of 1993. It is too early to observe possible effect on other types of cancer. However, mortality from suicides was increased compared with general population. Further follow-up and the extension to other Baltic countries in the future will undoubtedly strengthen the study. There are also plans for future projects covering areas from psychosocial factors to radiation biology

Diverticular Disease and Colorectal Cancer: Incidental Diagnosis or Real Association? Final Answer.

Science.gov (United States)

Regula, Jaroslaw

2016-10-01

Associations between diverticular disease of the colon and the colorectal cancer has been studied for >60 years. Observational, cross-sectional, and case-control studies as well as large population-based studies gave conflicting results and association was not fully proven. Obtaining the proof was difficult because both diseases share similar clinical characteristics, both increase with age, and both involve similar dietary factors. Long-term observations are difficult as diagnostic methods changed over time from barium enema 50 to 60 years ago, through endoscopy, up to CT and MR in recent years. Cancer or adenomas may be missed within diverticular segment; diverticula may be underreported in patients with colon cancer diagnosis. Most recent 2 large cohort studies have solved the dilemma. These studies have clearly shown that diverticular disease does not increase the risk of colon cancer after the first year of diagnosis. Within the first year of diagnosis the association is strong, most probably due to difficulties with differential diagnosis and misclassifications and shared symptoms. Findings of these studies have led to the conclusion that colon cancer has to be excluded using modern techniques after the first episode of suspected diverticulitis.

Oligometastatic disease at presentation or recurrence for nonsmall cell lung cancer.

Gomez, Daniel R; Niibe, Yuzuru; Chang, Joe Y

2012-01-01

Oligometastatic Non-Small Cell Lung Cancer (NSCLC) presents a unique opportunity for potential curative therapy. Improved cancer staging using PET/CT, MRI, and future cellular and molecular staging with circulating tumor cells and/or molecular markers will identify more patients with truly oligometastasis disease that will benefit from definitive local treatment. Recent development of noninvasive local ablative therapy such as stereotactic radiotherapy makes it possible to eradicate multiple local diseases with minimal side effect. Novel systemic therapy may also control systemic spread and therefore make it possible to improve survival by eliminating local diseases. More research, particularly prospective studies, is ideally randomized studies are needed to validate the concept of oligometastasis.

Enzalutamide, an oral androgen receptor inhibitor, significantly improved overall survival (OS) and radiographic progression-free survival (rPFS) versus placebo in the PREVAIL trial of men with chemotherapy-naïve metastatic castration-resistant prostate cancer. To assess the effects of enzalutamide versus placebo in patients from PREVAIL based on site and extent of baseline disease. One thousand seven hundred and seventeen asymptomatic or minimally symptomatic patients were randomized to enzalutamide (n=872) or placebo (n=845). Subgroup analyses included nonvisceral (only bone and/or nodal; n=1513), visceral (lung and/or liver; n=204), low-volume bone disease (1 in patients with visceral disease (HR, 0.82; 95% CI, 0.55-1.23). Enzalutamide was well tolerated in patients with or without visceral disease. Enzalutamide provided clinically significant benefits in men with chemotherapy-naïve metastatic castration-resistant prostate cancer, with or without visceral disease, low- or high-volume bone disease, or lymph node only disease. Patients with metastatic castration-resistant prostate cancer-including those with or without visceral disease or widespread bone disease-benefitted from enzalutamide, an active well-tolerated therapy.

Ovarian cancer is a heterogeneous disease and prognosis for apparently similar cases of ovarian cancer varies. Recurrence of the disease in early stage (FIGO-stages I-II) serous ovarian cancer results in survival that is comparable to those with recurrent advanced-stage disease. The aim of this study was to investigate if there are specific genomic aberrations that may explain recurrence and clinical outcome. Fifty-one women with early stage serous ovarian cancer were included in the study. DNA was extracted from formalin fixed samples containing tumor cells from ovarian tumors. Tumor samples from thirty-seven patients were analysed for allele-specific copy numbers using OncoScan single nucleotide polymorphism arrays from Affymetrix and the bioinformatic tool Tumor Aberration Prediction Suite. Genomic gains, losses, and loss-of-heterozygosity that associated with recurrent disease were identified. The most significant differences (p < 0.01) in Loss-of-heterozygosity (LOH) were identified in two relatively small regions of chromosome 19; 8.0-8,8 Mbp (19 genes) and 51.5-53.0 Mbp (37 genes). Thus, 56 genes on chromosome 19 were potential candidate genes associated with clinical outcome. LOH at 19q (51-56 Mbp) was associated with shorter disease-free survival and was an independent prognostic factor for survival in a multivariate Cox regression analysis. In particular LOH on chromosome 19q (51-56 Mbp) was significantly (p < 0.01) associated with loss of TP53 function. The results of our study indicate that presence of two aberrations in TP53 on 17p and LOH on 19q in early stage serous ovarian cancer is associated with recurrent disease. Further studies related to the findings of chromosomes 17 and 19 are needed to elucidate the molecular mechanism behind the recurring genomic aberrations and the poor clinical outcome

BACKGROUND: In numerous studies, alcohol intake has been found to be positively associated with colorectal cancer risk. However, the majority of studies included only one exposure measurement, which may bias the results if long-term intake is relevant.METHODS: We compared different approaches...... for including repeated measures of alcohol intake among 47,432 US men enrolled in the Health Professionals Follow-up Study. Questionnaires including questions on alcohol intake had been completed in 1986, 1990, 1994, and 1998. The outcome was incident colorectal cancer during follow-up from 1986 to 2002.RESULTS......: During follow-up, 868 members of the cohort experienced colorectal cancer. Baseline, updated, and cumulative average alcohol intakes were positively associated with colorectal cancer, with only minor differences among the approaches. These results support moderately increased risk for intake >30 g...

Early studies suggested that coffee consumption may increase the risk of chronic disease. We investigated prospectively the association between coffee consumption and the risk of chronic diseases, including type 2 diabetes (T2D), myocardial infarction (MI), stroke, and cancer. We used data from 42,659 participants in the European Prospective Investigation into Cancer and Nutrition (EPIC)-Germany study. Coffee consumption was assessed by self-administered food-frequency questionnaire at baseline, and data on medically verified incident chronic diseases were collected by active and passive follow-up procedures. HRs and 95% CIs were calculated with multivariate Cox regression models and compared by competing risk analysis. During 8.9 y of follow-up, we observed 1432 cases of T2D, 394 of MI, 310 of stroke, and 1801 of cancer as first qualifying events. Caffeinated (HR: 0.94; 95% CI: 0.84, 1.05) or decaffeinated (HR: 1.05; 95% CI: 0.84, 1.31) coffee consumption (≥4 cups/d compared with disease. A lower risk of T2D was associated with caffeinated (HR: 0.77; 95% CI: 0.63, 0.94; P-trend 0.009) and decaffeinated (HR: 0.70; 95% CI: 0.46, 1.06; P-trend: 0.043) coffee consumption (≥4 cups/d compared with disease and cancer risk were not. The competing risk analysis showed no significant differences between the risk associations of individual diseases. Our findings suggest that coffee consumption does not increase the risk of chronic disease, but it may be linked to a lower risk of T2D.

Full Text Available Objective: To report the level of utilization of clinical preventive services by older adults in Jamaica and to identify independent factors associated with utilization. Method: A nationally representative, community-based survey of 2,943 older adults was undertaken. Utilization frequency for six preventive, cardiovascular or cancer-related services was calculated. Logistic regression models were used to determine the independent factors associated with each service. Results: A dichotomy in annual utilization rates exists with cardiovascular services having much higher uptake than those for cancer (83.1% for blood pressure, 76.7% blood glucose, 68.1% cholesterol, 35.1% prostate, 11.3% mammograms, and 9.6% papanicolaou smears. Age, source of routine care, and having a chronic disease were most frequently associated with uptake. Discussion: Education of providers and patients on the need for utilizing preventive services in older adults is important. Improved access to services in the public sector may also help increase uptake of services.

Histones and their modifications in ovarian cancer - drivers of disease and therapeutic targets.

Marsh, Deborah J; Shah, Jaynish S; Cole, Alexander J

2014-01-01

Epithelial ovarian cancer has the highest mortality of the gynecological malignancies. High grade serous epithelial ovarian cancer (SEOC) is the most common subtype, with the majority of women presenting with advanced disease where 5-year survival is around 25%. Platinum-based chemotherapy in combination with paclitaxel remains the most effective treatment despite platinum therapies being introduced almost 40 years ago. Advances in molecular medicine are underpinning new strategies for the treatment of cancer. Major advances have been made by international initiatives to sequence cancer genomes. For SEOC, with the exception of TP53 that is mutated in virtually 100% of these tumors, there is no other gene mutated at high frequency. There is extensive copy number variation, as well as changes in methylation patterns that will influence gene expression. To date, the role of histones and their post-translational modifications in ovarian cancer is a relatively understudied field. Post-translational histone modifications play major roles in gene expression as they direct the configuration of chromatin and so access by transcription factors. Histone modifications include methylation, acetylation, and monoubiquitination, with involvement of enzymes including histone methyltransferases, histone acetyltransferases/deacetylases, and ubiquitin ligases/deubiquitinases, respectively. Complexes such as the Polycomb repressive complex also play roles in the control of histone modifications and more recently roles for long non-coding RNA and microRNAs are emerging. Epigenomic-based therapies targeting histone modifications are being developed and offer new approaches for the treatment of ovarian cancer. Here, we discuss histone modifications and their aberrant regulation in malignancy and specifically in ovarian cancer. We review current and upcoming histone-based therapies that have the potential to inform and improve treatment strategies for women with ovarian cancer.

Impact of preventive therapy on the risk of breast cancer among women with benign breast disease.

There are three main ways in which women can be identified as being at high risk of breast cancer i) family history of breast and/or ovarian cancer, which includes genetic factors ii) mammographically identified high breast density, and iii) certain types of benign breast disease. The last category is the least common, but in some ways the easiest one for which treatment can be offered, because these women have already entered into the treatment system. The highest risk is seen in women with lobular carcinoma in situ (LCIS), but this is very rare. More common is atypical hyperplasia (AH), which carries a 4-5-fold risk of breast cancer as compared to general population. Even more common is hyperplasia of the usual type and carries a roughly two-fold increased risk. Women with aspirated cysts are also at increased risk of subsequent breast cancer. Tamoxifen has been shown to be particularly effective in preventing subsequent breast cancer in women with AH, with a more than 70% reduction in the P1 trial and a 60% reduction in IBIS-I. The aromatase inhibitors (AIs) also are highly effective for AH and LCIS. There are no published data on the effectiveness of tamoxifen or the AIs for breast cancer prevention in women with hyperplasia of the usual type, or for women with aspirated cysts. Improving diagnostic consistency, breast cancer risk prediction and education of physicians and patients regarding therapeutic prevention in women with benign breast disease may strengthen breast cancer prevention efforts.

To characterize the impact of hospital and physician ovarian cancer case volume on survival for advanced-stage disease and investigate socio-demographic variables associated with access to high-volume providers. Consecutive patients with stage IIIC/IV epithelial ovarian cancer (1/1/96-12/31/06) were identified from the California Cancer Registry. Disease-specific survival analysis was performed using Cox-proportional hazards model. Multivariate logistic regression analyses were used to evaluate for differences in access to high-volume hospitals (HVH) (≥20 cases/year), high-volume physicians (HVP) (≥10 cases/year), and cross-tabulations of high- or low-volume hospital (LVH) and physician (LVP) according to socio-demographic variables. A total of 11,865 patients were identified. The median ovarian cancer-specific survival for all patients was 28.2 months, and on multivariate analysis the HVH/HVP provider combination (HR = 1.00) was associated with superior ovarian cancer-specific survival compared to LVH/LVP (HR = 1.31, 95%CI = 1.16-1.49). Overall, 2119 patients (17.9%) were cared for at HVHs, and 1791 patients (15.1%) were treated by HVPs. Only 4.3% of patients received care from HVH/HVP, while 53.1% of patients were treated by LVH/LVP. Both race and socio-demographic characteristics were independently associated with an increased likelihood of being cared for by the LVH/LVP combination and included: Hispanic race (OR = 1.72, 95%CI = 1.22-2.42), Asian/Pacific Islander race (OR = 1.57, 95%CI = 1.07-2.32), Medicaid insurance (OR = 2.51, 95%CI = 1.46-4.30), and low socioeconomic status (OR = 2.84, 95%CI = 1.90-4.23). Among patients with advanced-stage ovarian cancer, the provider combination of HVH/HVP is an independent predictor of improved disease-specific survival. Access to high-volume ovarian cancer providers is limited, and barriers are more pronounced for patients with low socioeconomic status, Medicaid insurance, and racial minorities. Copyright © 2013

Holmes, Jordan A.; Wang, Andrew Z.; Hoffman, Karen E.; Hendrix, Laura H.; Rosenman, Julian G.; Carpenter, William R.; Godley, Paul A.; Chen, Ronald C.

2012-01-01

Purpose: To examine the patterns of primary treatment in a recent population-based cohort of prostate cancer patients, stratified by the likelihood of extraprostatic cancer as predicted by disease characteristics available at diagnosis. Methods and Materials: A total of 157,371 patients diagnosed from 2004 to 2008 with clinically localized and potentially curable (node-negative, nonmetastatic) prostate cancer, who have complete information on prostate-specific antigen, Gleason score, and clinical stage, were included. Patients with clinical T1/T2 disease were grouped into categories of 50% likelihood of having extraprostatic disease using the Partin nomogram. Clinical T3/T4 patients were examined separately as the highest-risk group. Logistic regression was used to examine the association between patient group and receipt of each primary treatment, adjusting for age, race, year of diagnosis, marital status, Surveillance, Epidemiology and End Results database region, and county-level education. Separate models were constructed for primary surgery, external-beam radiotherapy (RT), and conservative management. Results: On multivariable analysis, increasing likelihood of extraprostatic disease was significantly associated with increasing use of RT and decreased conservative management. Use of surgery also increased. Patients with >50% likelihood of extraprostatic cancer had almost twice the odds of receiving prostatectomy as those with 50% likelihood of extraprostatic cancer (34%) and clinical T3–T4 disease (24%). The proportion of patients who received prostatectomy or conservative management was approximately 50% or slightly higher in all groups. Conclusions: There may be underutilization of RT in older prostate cancer patients and those with likely extraprostatic disease. Because more than half of prostate cancer patients do not consult with a radiation oncologist, a multidisciplinary consultation may affect the treatment decision-making process.

Drug Hypersensitivity and Anaphylaxis in Cancer and Chronic Inflammatory Diseases: The Role of Desensitizations

Directory of Open Access Journals (Sweden)

Mariana Castells

2017-11-01

Full Text Available Drug allergy is a rising problem in the twenty-first century which affects all populations and races, children, and adults, and for which the recognition, diagnosis, management, and treatment is still not well standardized. Classical and new chemotherapy drugs, monoclonal antibodies (MoAbs, and small molecules to treat cancer and chronic inflammatory diseases are aimed at improving quality of life and life expectancy of patients, but an increasing number of reactions including anaphylaxis precludes their use in targeted populations. Women are more affected by drug allergy and up to 27% of women with ovarian and breast cancer develop carboplatin allergy after multiple cycles of treatment. Carriers of BRCA genes develop drug allergy after fewer exposures and can present with severe reactions, including anaphylaxis. Atopic patients are at increased risk for chemotherapy and MoAbs drug allergy and the current patterns of treatment with recurrent and intermittent drug exposures may favor the development of drug allergies. To overcome drug allergy, desensitization has been developed, a novel approach which provides a unique opportunity to protect against anaphylaxis and to improve clinical outcomes. There is evidence that inhibitory mechanisms blocking IgE/antigen mast cell activation are active during desensitization, enhancing safety. Whether desensitization modulates drug allergic and anaphylactic responses facilitating tolerance is currently being investigated. This review provides insight into the current knowledge of drug allergy and anaphylaxis to cancer and chronic inflammatory diseases drugs, the mechanisms of drug desensitization and its applications to personalized medicine.

Full Text Available Oligometastatic Non-Small Cell Lung Cancer (NSCLC presents a unique opportunity for potential curative therapy. Improved cancer staging using PET/CT, MRI, and future cellular and molecular staging with circulating tumor cells and/or molecular markers will identify more patients with truly oligometastasis disease that will benefit from definitive local treatment. Recent development of noninvasive local ablative therapy such as stereotactic radiotherapy makes it possible to eradicate multiple local diseases with minimal side effect. Novel systemic therapy may also control systemic spread and therefore make it possible to improve survival by eliminating local diseases. More research, particularly prospective studies, is ideally randomized studies are needed to validate the concept of oligometastasis.

Medical advances continue to improve morbidity and mortality of serious pediatric diseases, including cancer, driving research addressing diminished physical and psychological quality of life in children with these chronic conditions. Empowerment enhances resilience and positively influences health, disease, and therapy understanding. We describe the development and usability assessment of a prototype Empower Stars! mobile video game grounded in behavioral and exercise theories with the purpose of coupling physical exercise with empowerment over disease in children with cancer. Academic faculty, health-care providers, and community video game developers collaborated in this project. The iPadAir was selected as a delivery platform for its accelerometer and gyroscope features facilitating exercise design. Unity multiplatform technology provided animation and audiovisual features for immediate player feedback. Javascript, C#, Photoshop, Flash, and SketchUp were used for coding, creating graphical assets, Sprite sheets, and printing files, respectively. 3D-printed handles and case backing were used to adapt the iPad for physical exercise. Game usability, engagement, and enjoyment were assessed via a multilevel study of children undergoing cancer chemotherapy, their parents, and pediatric cancer health-care providers. Feedback crucial for ongoing game development was analyzed. A prototype Empower Stars! mobile video game was developed for children 7-14 years old with cancer. Active, sedentary, educational, and empowerment-centered elements intermix for 20 min of exercise within a 30 min "one-day treatment" gameplay session involving superheroes, space exploration, metaphorical cancer challenges, life restoration on a barren planet, and innumerable star rewards. No player "dies." Usability assessment data analyses showed widespread enthusiasm for integrating exercise with empowerment over cancer and the game itself.

Few population-based studies have focused on cardiovascular disease (CVD) risk in adolescent and young adult (AYA; 15-39 years) cancer survivors and none have considered whether CVD risk differs by sociodemographic factors. Analyses focused on 79,176 AYA patients diagnosed with 14 first primary cancers in 1996-2012 and surviving > 2 years after diagnosis with follow-up through 2014. Data were obtained from the California Cancer Registry and State hospital discharge data. CVD included coronary artery disease, heart failure, and stroke. The cumulative incidence of developing CVD accounted for the competing risk of death. Multivariable Cox proportional hazards regression evaluated factors associated with CVD and the impact of CVD on mortality. Overall, 2249 (2.8%) patients developed CVD. Survivors of central nervous system cancer (7.3%), acute lymphoid leukemia (6.9%), acute myeloid leukemia (6.8%), and non-Hodgkin lymphoma (4.1%) had the highest 10-year CVD incidence. In multivariable models, African-Americans (hazard ratio (HR) = 1.55, 95% confidence interval (CI) = 1.33-1.81; versus non-Hispanic Whites), those with public/no health insurance (HR = 1.78, 95% CI = 1.61-1.96; versus private) and those who resided in lower socioeconomic status neighborhoods had a higher CVD risk. These sociodemographic differences in CVD incidence were apparent across most cancer sites. The risk of death was increased by eightfold or higher among AYAs who developed CVD. While cancer therapies are known to increase the risk of CVD, this study additionally shows that CVD risk varies by sociodemographic factors. The identification and mitigation of CVD risk factors in these subgroups may improve long-term patient outcomes.

The Prevent Cancer Foundation Lung Cancer Workshop XI: Tobacco-Induced Disease: Advances in Policy, Early Detection and Management was held in New York, NY on May 16 and 17, 2014. The two goals of the Workshop were to define strategies to drive innovation in precompetitive quantitative research on the use of imaging to assess new therapies for management of early lung cancer and to discuss a process to implement a national program to provide high quality computed tomography imaging for lung cancer and other tobacco-induced disease. With the central importance of computed tomography imaging for both early detection and volumetric lung cancer assessment, strategic issues around the development of imaging and ensuring its quality are critical to ensure continued progress against this most lethal cancer.

Human papillomavirus in cervical cancer and oropharyngeal cancer: One cause, two diseases.

Science.gov (United States)

Berman, Tara A; Schiller, John T

2017-06-15

Human papillomavirus (HPV) causes greater than 5% of cancers worldwide, including all cervical cancers and an alarmingly increasing proportion of oropharyngeal cancers (OPCs). Despite markedly reduced cervical cancer incidence in industrialized nations with organized screening programs, cervical cancer remains the second most common cause of death from cancer in women worldwide, as developing countries lack resources for universal, high-quality screening. In the United States, HPV-related OPC is only 1 of 5 cancers with a rising incidence since 1975 and now has taken over the cervix as the most common site of HPV-related cancer. Similar trends follow throughout North America and Europe. The need for early detection and prevention is paramount. Despite the common etiologic role of HPV in the development of cervical cancer and HPV-associated OPC, great disparity exists between incidence, screening modalities (or lack thereof), treatment, and prevention in these 2 very distinct cohorts. These differences in cervical cancer and HPV-associated OPC and their impact are discussed here. Cancer 2017;123:2219-2229. © 2017 American Cancer Society. Published 2017.

Gene expression profiling in cervical cancer: identification of novel markers for disease diagnosis and therapy.

LENUS (Irish Health Repository)

Martin, Cara M

2012-02-01

Cervical cancer, a potentially preventable disease, remains the second most common malignancy in women worldwide. Human papillomavirus is the single most important etiological agent in cervical cancer. HPV contributes to neoplastic progression through the action of two viral oncoproteins E6 and E7, which interfere with critical cell cycle pathways, p53, and retinoblastoma. However, evidence suggests that HPV infection alone is insufficient to induce malignant changes and other host genetic variations are important in the development of cervical cancer. Advances in molecular biology and high throughput gene expression profiling technologies have heralded a new era in biomarker discovery and identification of molecular targets related to carcinogenesis. These advancements have improved our understanding of carcinogenesis and will facilitate screening, early detection, management, and personalised targeted therapy. In this chapter, we have described the use of high density microarrays to assess gene expression profiles in cervical cancer. Using this approach we have identified a number of novel genes which are differentially expressed in cervical cancer, including several genes involved in cell cycle regulation. These include p16ink4a, MCM 3 and 5, CDC6, Geminin, Cyclins A-D, TOPO2A, CDCA1, and BIRC5. We have validated expression of mRNA using real-time PCR and protein by immunohistochemistry.

The role of ADAMs in disease pathophysiology.

LENUS (Irish Health Repository)

Duffy, Michael J

2012-02-01

The ADAMs are a family of multidomain transmembrane and secreted proteins involved in both proteolysis and cell adhesion. Altered expression of specific ADAMs is implicated in the pathophysiology of several diseases including rheumatoid arthritis, Alzheimer\\'s disease, cardiac hypertrophy, asthma and cancer. Of these different diseases, it is in cancer where most research has been carried out. Multiple ADAMs, including ADAM-9, ADAM-10, ADAM-12, ADAM-15 and ADAM-17, have been shown to play a role in either cancer formation or progression. Consistent with these findings, increased expression of specific ADAMs in several cancer types was found to correlate with features of aggressive disease and poor prognosis. Currently, selective ADAM inhibitors against ADAM-10 and ADAM-17 are undergoing clinical trials for the treatment of cancer. Further work is required in order to establish a causative role for ADAMs in rheumatoid arthritis, Alzheimer\\'s disease, cardiac hypertrophy and asthma.

Management of cancer-associated thrombosis in people with advanced disease.

Noble, Simon; Johnson, Miriam J

2012-06-01

The management of venous thromboembolism in the cancer population is clearly established. Low molecular weight heparin has a greater efficacy than warfarin in the treatment of cancer-associated thrombosis and is recommended as the preferred therapy. However, the evidence informing these recommendations excluded patients with poor prognosis or performance status, thrombocytopenia, bleeding or brain metastases. Furthermore, there is limited data on the management of venous thromboembolism resistant to anticoagulation, a phenomenon frequently encountered in the advanced cancer population. This paper will review the management of cancer-associated thrombosis with a particular focus on challenging clinical situations faced by palliative care teams looking after patients with advanced disease.

The expanding universe of cohesin functions: a new genome stability caretaker involved in human disease and cancer.

Cohesin is responsible for sister chromatid cohesion, ensuring the correct chromosome segregation. Beyond this role, cohesin and regulatory cohesin genes seem to play a role in preserving genome stability and gene transcription regulation. DNA damage is thought to be a major culprit for many human diseases, including cancer. Our present knowledge of the molecular basis underlying genome instability is extremely limited. Mutations in cohesin genes cause human diseases such as Cornelia de Lange syndrome and Roberts syndrome/SC phocomelia, and all the cell lines derived from affected patients show genome instability. Cohesin mutations have also been identified in colorectal cancer. Here, we will discuss the human disorders caused by alterations of cohesin function, with emphasis on the emerging role of cohesin as a genome stability caretaker.

Role of antioxidants in disease and cancer prevention: a literature review

This review was written on data collected from, review articles, cross-sectional studies, randomized control trials, open-label studies, critical reviews, Cochrane data base system reviews, meta-analysis, population based trials, different phase-I and phase-II trials reported in literature between 1993 to 2014. Web sites and other online resources of Medline, NCBI, Pub med, Medscape resource centers, American college of surgeons were used to extract the data. The debate about the role of antioxidant therapy in disease or cancer prevention has long-loomed. Oxidative damage induced by free radicals has been implicated in most inflammatory and degenerative diseases. Scientific research has reported that the antioxidants may have a role in carcinogenesis, while antioxidant-containing fruits, vegetables may protect against some of these diseases while the role of supplements containing antioxidants in the prevention of chronic diseases remains unproven. This review provides basic information about antioxidants and summarizes different studies reported in literature about the role antioxidants in disease or cancer prevention. (author)

To evaluate the incidence of thyroid carcinoma in patients operated on for Graves' disease, to identify criteria which may predict malignancy, and to develop a practical approach to determine the extensiveness of thyroidectomy. Retrospective study of all patients who underwent thyroidectomy for Graves' disease between 1995 and 2005. 547 patients underwent subtotal thyroidectomy for Graves' disease during this period. Post-operative pathology examination revealed six cases of thyroid cancer (1.1%). All six cases had differentiated thyroid carcinoma (papillary carcinoma in 3 cases, follicular carcinoma in 2 cases and papillo-follicular carcinoma in 1 case). The indication for initial thyroidectomy was a palpable thyroid nodule in 3 cases (50%), failure of medical treatment for Grave's disease in 2 cases (33%), and signs of goiter compression in 1 case (17%). Five patients underwent re-operative total thyroidectomy. This study shows that while malignancy in Grave's disease is uncommon, the presence of thyroid nodule(s) in patients with Grave's disease may be considered as an indication for radical surgery. The most adequate radical surgery in this situation is to perform a total thyroidectomy.

The main role of vitamin D is regulating bone metabolism and calcium and phosphorus homeostasis. Over the past few decades, the importance of vitamin D in non-skeletal actions has been studied, including the role of vitamin D in autoimmune diseases, metabolic syndromes, cardiovascular disease, cancers, and all-cause mortality. Recent evidence has demonstrated an association between low vitamin D status and autoimmune thyroid diseases such as Hashimoto's thyroiditis and Graves' disease, and impaired vitamin D signaling has been reported in thyroid cancers. This review will focus on recent data on the possible role of vitamin D in thyroid diseases, including autoimmune thyroid diseases and thyroid cancers.

PURPOSE: The aim of the study was to examine the potential association between a history of pelvic inflammatory disease (PID) and risk of epithelial ovarian cancer or ovarian borderline tumors. METHODS: In a population-based case-control study in Denmark, we included 554 women with invasive ovarian...... cancer, 202 with ovarian borderline tumors, and 1,564 controls aged 35-79 years. The analyses were performed in multiple logistic regression models. RESULTS: We found a significantly increased risk of ovarian borderline tumors among women with a history of PID (OR = 1.50; 95% CI 1.......08-2.08) but no apparent association between PID and risk of invasive ovarian cancer (OR = 0.83; 95% CI 0.65-1.05). We found no effect of age at time of first PID or time since first PID on the risk for either condition. CONCLUSION: Our results suggest that a history of PID is associated with an increased risk of ovarian...

Cancer and Scleroderma: A Paraneoplastic Disease with Implications for Malignancy Screening

Science.gov (United States)

Shah, Ami A.; Rosen, Livia Casciola

2015-01-01

Purpose of review Recent data suggest a paraneoplastic mechanism of scleroderma pathogenesis in unique subsets of scleroderma patients. In this article, we review these data, explore potential links between cancer and scleroderma, and propose an approach to malignancy screening in scleroderma. Recent findings Emerging data have demonstrated that patients with scleroderma and RNA polymerase III autoantibodies have a significantly increased risk of cancer within a few years of scleroderma onset. Genetic alterations in the gene encoding RNA polymerase III (POLR3A) have been identified, and patients with somatic mutations in POLR3A have evidence of mutation specific T cell immune responses with generation of cross-reactive RNA polymerase III autoantibodies. These data strongly suggest that scleroderma is a by-product of anti-tumor immune responses in some patients. Additional epidemiologic data demonstrate that patients developing scleroderma at older ages may also have a short cancer-scleroderma interval, suggestive of paraneoplastic disease. Summary Scleroderma may be a paraneoplastic disease in unique patient subsets. Aggressive malignancy screening in these patients may aid in early cancer detection. Further study is required to determine whether cancer therapy could improve scleroderma outcomes in this patient population. PMID:26352736

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.

Brothers, Joel M; Kidwell, Kelley M; Brown, Richard K J; Henry, N Lynn

2016-01-01

Despite guidelines recommending against its routine use, perioperative imaging for distant metastases is frequently performed in newly diagnosed breast cancer patients, uncovering incidental findings of uncertain significance. We assessed the clinical significance of incidental findings by determining if their presence is associated with disease recurrence. A retrospective review of staging imaging was performed in patients with stage II or III invasive breast cancer diagnosed during 2008-2009 at a large academic medical center. Data related to perioperative imaging and disease recurrence were abstracted from the medical record. Kaplan-Meier curves and Cox proportional hazards models were used to assess the association between incidental findings and time to disease recurrence. A total of 169 of 340 patients (49.7 %) underwent staging evaluation for distant metastases (CT chest, abdomen, pelvis, bone scan, and/or PET-CT). Of these, 146 (86.4 %) had at least one suspicious or indeterminate finding. Follow-up studies were performed in 73 (43.2 %) patients. Nineteen patients were diagnosed with metastatic disease at diagnosis, 18 of whom had stage III disease. In patients without metastatic disease at diagnosis, 32 later developed recurrence. Non-calcified pulmonary nodules were associated with shorter time to disease recurrence (hazard ratio 2.51, 95 % CI 1.13-5.57, p = 0.02). Imaging for distant metastases frequently reveals indeterminate findings, most of which are not associated with disease recurrence. The association between pulmonary nodules and recurrence warrants validation in an independent cohort. Overall, these findings support current guidelines recommending against routine extent of disease evaluation in patients with newly diagnosed stage II breast cancer.

NASA Models of Space Radiation Induced Cancer, Circulatory Disease, and Central Nervous System Effects

The risks of late effects from galactic cosmic rays (GCR) and solar particle events (SPE) are potentially a limitation to long-term space travel. The late effects of highest concern have significant lethality including cancer, effects to the central nervous system (CNS), and circulatory diseases (CD). For cancer and CD the use of age and gender specific models with uncertainty assessments based on human epidemiology data for low LET radiation combined with relative biological effectiveness factors (RBEs) and dose- and dose-rate reduction effectiveness factors (DDREF) to extrapolate these results to space radiation exposures is considered the current "state-of-the-art". The revised NASA Space Risk Model (NSRM-2014) is based on recent radio-epidemiology data for cancer and CD, however a key feature of the NSRM-2014 is the formulation of particle fluence and track structure based radiation quality factors for solid cancer and leukemia risk estimates, which are distinct from the ICRP quality factors, and shown to lead to smaller uncertainties in risk estimates. Many persons exposed to radiation on earth as well as astronauts are life-time never-smokers, which is estimated to significantly modify radiation cancer and CD risk estimates. A key feature of the NASA radiation protection model is the classification of radiation workers by smoking history in setting dose limits. Possible qualitative differences between GCR and low LET radiation increase uncertainties and are not included in previous risk estimates. Two important qualitative differences are emerging from research studies. The first is the increased lethality of tumors observed in animal models compared to low LET radiation or background tumors. The second are Non- Targeted Effects (NTE), which include bystander effects and genomic instability, which has been observed in cell and animal models of cancer risks. NTE's could lead to significant changes in RBE and DDREF estimates for GCR particles, and the potential

Background: Periodontal pathogens have been isolated from precancerous and cancerous lesions and also shown to promote a procarcinogenic microenvironment. Few studies have examined periodontal disease as a risk factor for total cancer, and none have focused on older women. We examined whether periodontal disease is associated with incident cancer among postmenopausal women in the Women's Health Initiative Observational Study. Methods: Our prospective cohort study comprised 65,869 women, ages 54 to 86 years. Periodontal disease information was obtained via self-report questionnaires administered between 1999 and 2003, whereas ascertainment of cancer outcomes occurred through September 2013, with a maximum follow-up period of 15 years. Physician-adjudicated incident total cancers were the main outcomes and site-specific cancers were secondary outcomes. HRs and 95% confidence intervals (CI) were calculated using Cox proportional hazards regression. All analyses were conducted two-sided. Results: During a mean follow-up of 8.32 years, 7,149 cancers were identified. Periodontal disease history was associated with increased total cancer risk (multivariable-adjusted HR, 1.14; 95% CI, 1.08-1.20); findings were similar in analyses limited to 34,097 never-smokers (HR, 1.12; 95% CI, 1.04-1.22). Associations were observed for breast (HR, 1.13; 95% CI, 1.03-1.23), lung (HR, 1.31; 95% CI, 1.14-1.51), esophagus (HR, 3.28; 95% CI, 1.64-6.53), gallbladder (HR, 1.73; 95% CI, 1.01-2.95), and melanoma skin (HR, 1.23; 95% CI, 1.02-1.48) cancers. Stomach cancer was borderline (HR, 1.58; 95% CI, 0.94-2.67). Conclusions: Periodontal disease increases risk of total cancer among older women, irrespective of smoking, and certain anatomic sites appear to be vulnerable. Impact: Our findings support the need for further understanding of the effect of periodontal disease on cancer outcomes.

Lee, Irwin H.; Roberts, Rebecca; Shah, Rajal B.; Wojno, Kirk J.; Wei, John T.; Sandler, Howard M.

2007-01-01

Purpose: To determine if perineural invasion (PNI) should be included in addition to prostate-specific antigen (PSA), biopsy Gleason score, and clinical T-stage for risk-stratification of patients with localized prostate cancer. Methods and Materials: We analyzed prostatectomy findings for 1550 patients, from a prospectively collected institutional database, to determine whether PNI was a significant predictor for upgrading of Gleason score or pathologic T3 disease after patients were stratified into low-, intermediate-, and high-risk groups (on the basis of PSA, biopsy Gleason score, and clinical T-stage). Results: For the overall population, PNI was associated with a significantly increased frequency of upgrading and of pathologic T3 disease. After stratification, PNI was still associated with significantly increased odds of pathologic T3 disease within each risk group. In particular, for low-risk patients, there was a markedly increased risk of extraprostatic extension (23% vs. 7%), comparable to that of intermediate-risk patients. Among high-risk patients, PNI was associated with an increased risk of seminal vesicle invasion and lymph node involvement. Furthermore, over 80% of high-risk patients with PNI were noted to have an indication for postoperative radiation. Conclusions: Perineural invasion may be useful for risk-stratification of prostate cancer. Our data suggest that low-risk patients with PNI on biopsy may benefit from treatment typically reserved for those with intermediate-risk disease. In addition, men with high-risk disease and PNI, who are contemplating surgery, should be informed of the high likelihood of having an indication for postoperative radiation therapy

Lung cancer and bronchi-pulmonary diseases of iron uranium miners

Gneusheva, G. I.; Uspenskaya, K. M.

2004-01-01

The lung cancer mortality has been analyzed for 2.582 miners employed from 1943 to 1961. All persons observed had three years occupation at least. Basing upon the lung cancer risk value per unit of the exposure, the assessment of the effective standard of pulmonary organ irradiation to radon progeny was elaborated and mortality excess was calcuated. Medical demography studies of morbidity and mortality were elaborated for silicosis, silicotuberculosis, lung cancer and occupational bronchitis versus the magnitude of dust and radiation exposure. Annual and cumulative exposures have been assessed for seven cohorts of miners employed and vast primary material has been accumulated for the period of 40 years (1943-1984). Intensive indice of mortality were determined for observation periods. The mortality excess was compared to cumulated radiation exposure. The lung cancer mortality excess in iron-uranium miners was 3.3 cases per 106 man-years per 1 WLM; 4.8 cases per 106 man-years per 1 WLM was assessed if first years of occupation are negected. The latent period from radiation exposure to death from lung cancer is generally ten year or more. Changes of miners labor conditions (the magnitude of dust exposure) have been reflected by the bronchi pulmonary disease structure. The input of these dieseases into the occupational lung pathology has been significantly changed with the time course. Within first 18-20 years, pneumoconiosis was the only form of occupational lung pathology in the mine, whereas occupational bronchis and lung cancers were recorded within next then years thereafter. In cohorts of longest observation period, the average age of patients was increasingly ranked versus diseases as follows: silicosis, silicotuberculosis, chronic bronchitis, and lung cancer. (Author)

The aim of this study was to determine predictors of locally advanced disease at presentation and clinical outcomes among cervical cancer patients in Botswana to inform interventional strategies. Retrospective review of 149 medical records of new cervical cancer patients was conducted between August 2016 and February 2017 at the Princess Marina Hospital. Data collected included sociodemographics, presenting symptoms, stage of disease, comorbidities, interventions, and clinical outcomes. STATA 12 was used for data analysis. Frequencies were used to describe patient demographics and clinical variables. Bivariate and multivariate binary logistic regression analyses were used to determine association between stage of disease at presentation and patient characteristics. P ≤ 0.05 was considered significant. Mean age was 49.5 years. Nine (89.2%) in 10 patients had locally advanced cervical cancer (stage IB1-IVB). Two thirds (65.1%) were human immunodeficiency virus positive. Previous cervical cancer screening was low at 38.3%. Common symptoms were abnormal vaginal bleeding, low abdominal pain, and malodorous vaginal discharge reported among 75.8%, 66.4%, and 39.6% of cases, respectively. Overall, 32 (21.5%) were declared cured, 52 (34.9%) improved, and 11 (7.4%) opted for home-based care. Hospital deaths were 41 (27.5%). Major causes of death were renal failure (48.7%) and severe anemia (39%). Thirteen (8.7%) were lost to follow-up. Being unmarried (odds ratio [OR], 3.9), lack of cervical cancer screening (OR, 6.68), presentation with vaginal bleeding (OR, 7.69), and low abdominal pain (OR, 4.69) were associated with advanced disease at presentation. Lack of cervical cancer screening, vaginal bleeding, low abdominal pain, and unmarried status were associated with advanced disease at presentation. We recommend scale-up of cervical cancer screening and its integration into routine human immunodeficiency virus care. Capacity building in gynecologic oncology and palliative

Pancreas cancer, or pancreatic ductal adenocarcinoma, is the deadliest of solid tumors, with a five-year survival rate of pancreas cancer. Mouse models that accurately recapitulate the human condition allow disease tracking from inception to invasion and can therefore be useful for studying early disease stages in which surgical resection is possible. Using a highly faithful mouse model of pancreas cancer in conjunction with a high-density antibody microarray containing ∼2500 antibodies, we interrogated the pancreatic tissue proteome at preinvasive and invasive stages of disease. The goal was to discover early stage tissue markers of pancreas cancer and follow them through histologically defined stages of disease using cohorts of mice lacking overt clinical signs and symptoms and those with end-stage metastatic disease, respectively. A panel of seven up-regulated proteins distinguishing pancreas cancer from normal pancreas was validated, and their levels were assessed in tissues collected at preinvasive, early invasive, and moribund stages of disease. Six of the seven markers also differentiated pancreas cancer from an experimental model of chronic pancreatitis. The levels of serine/threonine stress kinase 4 (STK4) increased between preinvasive and invasive stages, suggesting its potential as a tissue biomarker, and perhaps its involvement in progression from precursor pancreatic intraepithelial neoplasia to pancreatic ductal adenocarcinoma. Immunohistochemistry of STK4 at different stages of disease revealed a dynamic expression pattern further implicating it in early tumorigenic events. Immunohistochemistry of a panel of human pancreas cancers confirmed that STK4 levels were increased in tumor epithelia relative to normal tissue. Overall, this integrated approach yielded several tissue markers that could serve as signatures of disease stage, including early (resectable), and therefore clinically meaningful, stages. © 2014 by The American Society for

Background In the present study we review and discuss the current evidence and suggest how to proceed in the management of oligometastatic disease in upper gastrointestinal cancer. Methods An electronic search of the PubMed database for relevant articles was performed. Results Both the search for ‘oligometastasis', ‘oligometastases', ‘oligometastatic’, ‘oligometastatic disease’ as well as ‘esophageal’ and ‘esophageal cancer’ and the search for ‘oligometastasis', ‘oligometastases', ‘oligometastatic’, ‘oligometastatic disease’ as well as ‘gastric’, ‘gastric cancer’, ‘stomach’, and ‘stomach cancer’ yielded very few studies. Most data need to be extrapolated in general studies on oligometastatic diseases of different origins. No randomized controlled trial could be found. Conclusion In the absence of data to formulate recommendations on how to proceed in the treatment of oligometastatic disease in upper gastrointestinal cancer, a more aggressive treatment of oligometastatic disease can be considered in patients whose tumors show a more favorable neoplastic behavior after the ‘test of time’. The RENAISSANCE study will certainly deliver important data regarding this aspect. PMID:28612014

Testicular cancer update.

2017-05-01

The advances seen in the treatment of testicular cancer are among the great achievements in modern medicine. These advances were made possible by the collaborative efforts of cancer researchers around the world. Investigators have been able to address many questions regarding the treatment of patients with disease limited to the testis, those with metastasis to the retroperitoneum only, and those with advanced metastatic disease. Questions answered include the chemotherapeutic agents to be used and in what combinations, the proper intensity of treatment and appropriate dosing, the optimal number of cycles of chemotherapy according to validated risk stratification, appropriate surgical approaches that preserve sexual function, the treatment of relapsed disease, what supportive care measures to take, and survivorship issues following treatment of testicular cancer. Today, cure is achievable in 95% of all patients with testicular cancer and 80% of those who have metastatic disease. Despite remarkable results with frontline and salvage combination chemotherapy, metastatic testicular cancer remains incurable in approximately 10% of patients, and novel treatment approaches are warranted. This review highlights past and recent discoveries in the treatment of patients with testicular cancer.

Sudden bilateral hearing loss in gastric cancer as the only symptom of disease

Because common signs of stomach cancer were absent, the patient was first evaluated in the Department of Otolaryngology, University Hospital Center, Zagreb. Only after expanded diagnostic evaluation and rapid progression of the disease in such a case is a malignant tumor suspected. Treatment is mostly ineffective. The unusual presentation of the disease and the rapid course may indicate a hereditary predisposition. Inactivation of tumor suppressor gene DFNA5 was found in 50% of gastric cancers, but of a non-metastasized phenotype. Inactivated DFNA5, otherwise described in hereditary bilateral deafness, perhaps favors the development of deafness in patients with gastric cancer. Our patient had a positive multiple viral antibody titer in serum, inactivated DFNA5 in both gastric cancer tissues and cerebellar metastases, and a metastatic form of the disease. If sudden deafness occurs in elderly patients, the possibility of malignant tumor should be taken into consideration. The link between gastric cancer and the DFNA5 gene is unclear and requires further research. Keywords: deafness, gastric cancer, DFNA5 gene, meningeal carcinomatosis

Secondary lymphoid organs are integral to initiation and execution of adaptive immune responses. These organs provide a setting for interactions between antigen-specific lymphocytes and antigen-presenting cells recruited from local infected or inflamed tissues. Secondary lymphoid organs develop as a part of a genetically preprogrammed process during embryogenesis. However, organogenesis of secondary lymphoid tissues can also be recapitulated in adulthood during de novo lymphoid neogenesis of tertiary lymphoid structures (TLSs). These ectopic lymphoid-like structures form in the inflamed tissues afflicted by various pathological conditions, including cancer, autoimmunity, infection, or allograft rejection. Studies are beginning to shed light on the function of such structures in different disease settings, raising important questions regarding their contribution to progression or resolution of disease. Data show an association between the tumor-associated TLSs and a favorable prognosis in various types of human cancer, attracting the speculation that TLSs support effective local antitumor immune responses. However, definitive evidence for the role for TLSs in fostering immune responses in vivo are lacking, with current data remaining largely correlative by nature. In fact, some more recent studies have even demonstrated an immunosuppressive, tumor-promoting role for cancer-associated TLSs. In this review, we will discuss what is known about the development of cancer-associated TLSs and the current understanding of their potential role in the antitumor immune response. PMID:29312327

This article summarizes the results of a recent study of atomic bomb radiation and non-cancer diseases in the AHS (Adult Health Study) population by the RERF (Radiation Effects Research Foundation) along with a general discussion of previous studies. Recent studies have demonstrated almost certainly that uterine myoma is more frequent among atomic bomb survivors. It cannot, at present, be concluded that uterine myoma is caused by radiation, because there are no reported studies of other exposed populations. Further analyses including the role of confounding factors as well as molecular approaches are needed to verify this radiation effect. The relationship between atomic bomb radiation exposure and hyperparathyroidism can now be said to have been established in view of the strong dose response, the agreement with results of studies of other populations, the high risk in the younger survivors, and the biological plausibility. Future studies by molecular approaches, etc., are needed to determine the pathogenic mechanism. Among other benign tumours, a dose response has been demonstrated for tumours of the thyroid, stomach and ovary. Although fewer studies have been conducted than for cancer, a clear association between radiation and various benign tumours is emerging. 79 refs, 5 figs, 1 tab

Extramammary Paget's disease (EMPD) is a rare intraepidermal adenocarcinoma that primarily affects the anogenital region. Cases of EMPD reacting with PSA (prostate-specific antigen) have previously been associated with underlying prostate cancer. However, a recent case of EMPD in our department has...... led us to question the value of PSA as an indicator of underlying prostate cancer. Clinical and pathological data were obtained for 16 cases of EMPD. Formalin-fixed, paraffin-embedded tissue blocks from the primary skin lesions were investigated using PSA and other immunohistochemical markers. 5...... of the 16 cases of EMPD stained positive for PSA (2 women and 3 men). However, no reactivity was seen for the prostatic marker P501S. Three of the five patients had been diagnosed with internal malignant disease-two with prostate cancer, stage 1. Immunohistochemical investigations of the tumour specimens...

The extracellular matrix and the interactive signalling between its components are thought to play a pivotal role for tumour development and metastasis formation. An altered matrix composition as potential underlying pathology for the development of colorectal cancer was hypothesized. In a retrospective study of patients with colon cancer, the extracellular matrix in tumour-free bowel specimen was investigated in comparison with non-infected bowel specimen from patients operated on for colonic diverticulosis. The following matrix parameters with known associations to tumour formation, cell proliferation, invasion and metastasis were analysed by immunohistochemistry and quantified by a scoring system: VEGF, TGF-beta, ESDN, CD117, c-erb-2, cyclin D1, p53, p27, COX-2, YB-1, collagen I/III, MMP-13, PAI and uPAR. Expression profiles and correlations were calculated. The comparison of the two groups revealed a significantly decreased immunostaining for CD117 and TGF-beta in the cancer group (8.5+/-2.6 vs 10.3+/-2,1 and 4.9+/-1.5 vs 8.1+/-3, respectively), whereas PAI scores were significantly higher than in patients with diverticular disease (8.1+/-1.6 vs 6.2+/-0.9). Overall correlation patterns of matrix parameters indicated pronounced differences between tumour-free tissue in cancer patients compared with patients with diverticular disease. Our results indicate distinct differences in the colonic tissue architecture between cancer patients and patients with diverticulitis that support the notion of an altered matrix composition predisposing to the development of colon cancer.

A 74-year-old man had an endoscopic type 0'-IIc tumor in the upper gastric body on the greater curvature and biopsy showed the tumor to be a well-differentiated adenocarcinoma (Group 5). He was referred to us for endoscopic submucosal dissection (ESD). Endoscopy revealed fold convergency, fold swelling, and fusion of the fold, indicating tumor invasion into the submucosa, which was outside the indications for ESD. In addition, there was an increase of serum bone-type alkaline phosphatase (ALP-III and ALP-IV) and urinary cross-linked N-terminal telopeptide of type I collagen (a bone metabolism marker), while (18)F-fluorodeoxyglucose positron emission tomography showed increased uptake in the left pelvis and Th10, suggesting bone metastases. We first diagnosed gastric cancer with bone metastases; however, the symptoms suggested pathological bone fracture and no bone pain. Therefore, a computed tomography-guided aspiration bone biopsy was performed to exclude the possibility of Paget's disease of bone. Biopsy specimens revealed no tumor and a mosaic pattern. No increased uptake of (18)F-FAMT (L-[3-(18)F] α-methyltyrosine) supported a diagnosis of no bone metastases from gastric cancer. We finally diagnosed gastric cancer accompanied by Paget's disease of bone and performed a laparoscopy-assisted proximal gastrectomy. The pathological diagnosis was U less 0-IIb, and U post 0-IIc ypT1a (M) N0H0P0M0 yp stage IA. In gastric cancer patients with suspected bone metastasis, we also need to consider Paget's disease of bone.

The optimal chemotherapy regimen for non-small cell lung cancer patients with interstitial lung disease is unclear. We therefore investigated the safety and efficacy of carboplatin plus nab-paclitaxel as a first-line regimen for non-small cell lung cancer in patients with interstitial lung disease. We retrospectively reviewed advanced non-small cell lung cancer patients with interstitial lung disease who received carboplatin plus nab-paclitaxel as a first-line chemotherapy regimen at Hyogo Cancer Center between February 2013 and August 2016. interstitial lung disease was diagnosed according to the findings of pretreatment chest high-resolution computed tomography. Twelve patients were included (male, n = 11; female, n = 1). The overall response rate was 67% and the disease control rate was 100%. The median progression free survival was 5.1 months (95% CI: 2.9-8.3 months) and the median overall survival was 14.9 months (95% CI: 4.8-not reached). A chemotherapy-related acute exacerbation of interstitial lung disease was observed in one patient; the extent of this event was Grade 2. There were no treatment-related deaths. Carboplatin plus nab-paclitaxel, as a first-line chemotherapy regimen for non-small cell lung cancer, showed favorable efficacy and safety in patients with preexisting interstitial lung disease. © The Author 2017.

Mechanical stress as the common denominator between chronic inflammation, cancer and Alzheimer’s disease

Directory of Open Access Journals (Sweden)

Marcel eLevy Nogueira

2015-09-01

Full Text Available The pathogenesis of common diseases such as Alzheimer’s disease (AD and cancer are currently poorly understood. Inflammation is a common risk factor for cancer and AD. Recent data, provided by our group and from others, demonstrate that increased pressure and inflammation are synonymous. There is a continuous increase in pressure from inflammation to fibrosis and then cancer. This in line with the numerous papers reporting high interstitial pressure in cancer. But most authors focus on the role of pressure in the lack of delivery of chemotherapy in the center of the tumor. Pressure may also be a key factor in carcinogenesis. Increased pressure is responsible for oncogene activation and cytokine secretion. Accumulation of mechanical stress plays a key role in the development of diseases of old age such as cardiomyopathy, atherosclerosis and osteoarthritis. Growing evidence suggest also a possible link between mechanical stress in the pathogenesis of AD. The aim of this review is to describe environmental and endogenous mechanical factors possibly playing a pivotal role in the mechanism of chronic inflammation, AD and cancer.

Lung cancer continues to be one of the most common causes of cancer death despite understanding the major cause of the disease: cigarette smoking. Smoking increases lung cancer risk 5- to 10-fold with a clear dose-response relationship. Exposure to environmental tobacco smoke among nonsmokers increases lung cancer risk about 20%. Risks for marijuana and hookah use, and the new e-cigarettes, are yet to be consistently defined and will be important areas for continued research as use of these products increases. Other known environmental risk factors include exposures to radon, asbestos, diesel, and ionizing radiation. Host factors have also been associated with lung cancer risk, including family history of lung cancer, history of chronic obstructive pulmonary disease and infections. Studies to identify genes associated with lung cancer susceptibility have consistently identified chromosomal regions on 15q25, 6p21 and 5p15 associated with lung cancer risk. Risk prediction models for lung cancer typically include age, sex, cigarette smoking intensity and/or duration, medical history, and occupational exposures, however there is not yet a risk prediction model currently recommended for general use. As lung cancer screening becomes more widespread, a validated model will be needed to better define risk groups to inform screening guidelines.

1997-01-01

Background: Treatment of locally advanced and recurrent rectal cancer usually has a high local recurrence rate and poor survival. Promising results have been reported by combined external radiotherapy, extensive surgery and intraoperative radiotherapy (IORT). Methods: One hundred fifteen patients with locally advanced rectal cancers fixed to the pelvic wall or locally recurrent rectal cancers underwent preoperative external radiotherapy with 46-50 Gy. Six to 8 weeks later radical pelvic surgery was attempted, and was combined with intraoperative electron beam radiotherapy (15-20 Gy) in 66 patients. The patients were followed closely to evaluate complication rate, local and distant recurrence rate and survival. Results: Surgery with no macroscopic tumour remaining was obtained in 65% of the patients with no postoperative deaths. Pelvic infection was the major complication (21%). Although the observation time is short (3-60 months), the local recurrence rate seems low (22%) and survival seems promising (about 60% at 4 years) in patients with complete tumour resection, in contrast to patients with residual tumour (none living at 4 years). Conclusions: The combined modality treatment with preoperative external radiotherapy and extensive pelvic surgery with IORT is sufficiently promising to start a randomized trial on the clinical value of IORT as a boost treatment in the multidisciplinary approach to this disease

A cohort study designed to evaluate the carcinogenicity of treatment for Hodgkin's disease (HD) was begun in 1976. This report describes 1,553 patients diagnosed with HD in 1940-75 and presents an analysis of follow-up findings through 1976. Twenty-seven cancers (excluding basal cell and squamous cell carcinomas of skin, trichoepitheliomas, and in situ carcinomas of cervix uteri) were observed 1 year or more after diagnosis of HD, including 6 leukemias. The relative risk (RR) of leukemia in patients treated with intensive chemotherapy with or without radiotherapy relative to general population incidence rates was 140 (95% confidence limits: 50,300). In the subgroup treated with both intensive radiotherapy and intensive chemotherapy, the RR of leukemia was 270 (95% confidence limits: 56,800). No leukemia occurred after treatment with intensive radiotherapy without chemotherapy. For cancers other than leukemia and for non-HD lymphomas, RR was generally not significantly different from the null value one

Seven cases of lung cancer were observed in patients with Hodgkin's disease (HD) since 1970. The risk ratio for the development of lung cancer among HD patients was 5.6 times that expected in the general population. The pertinent clinical data from these patients are described and compared to 28 additional patients reported from other institutions. Small-cell lung cancer represented the predominant histologic type of lung cancer encountered in both smoking and nonsmoking patients with HD, accounting for 42% of cases overall and greater than 55% of cases reported in reviews of second malignancies. Tobacco use was noted in only 53% of patients. Twenty-eight (94%) of 30 patients developing metachronous lung cancer received supradiaphragmatic irradiation as primary therapy for HD. Nineteen (68%) of these patients received subsequent chemotherapy salvage. The median age at diagnosis of HD and lung cancer was 39 and 45 years, respectively. The interval between diagnosis of HD and metachronous lung cancer averaged seven years but appeared to vary inversely with age. HD patients treated with supradiaphragmatic irradiation or combined modality therapy may be at increased risk for developing lung cancer. The high frequency of in-field malignancies that the authors observed and the prevalence of small-cell lung cancer in both smoking and nonsmoking patients suggests that chest irradiation may influence the development of metachronous lung cancer in these patients. The finding of a mean latent interval in excess of seven years emphasizes the need for close long-term observation

The innate immune signaling in cancer and cardiometabolic diseases: Friends or foes?

The innate immune system is responsible for sensing pathogen-associated molecular patterns (PAMPs) or danger-associated molecular patterns (DAMPs) by several types of germline-encoded pattern-recognition receptors (PRRs). It has the capacity to help the human body maintain homeostasis under normal conditions. However, in pathological conditions, PAMPs or DAMPs trigger aberrant innate immune and inflammatory responses and thus negatively or positively influence the progression of cancer and cardiometabolic diseases. Interestingly, we found that some elements of innate immune signaling are involved in these diseases partially via immune-independent manners, indicating a deeper understanding of the function of innate immune signaling in these diseases is urgent. In this review, we summarize the primary innate immune signaling pathways and their association with cancer and cardiometabolic diseases, with the aim of providing effective therapies for these diseases.

2011-06-03

INTRODUCTION: Breast-conserving surgery (BCS), followed by appropriate adjuvant therapies is established as a standard treatment option for women with early-stage invasive breast cancers. A number of factors have been shown to correlate with local and regional disease recurrence. Although margin status is a strong predictor of disease recurrence, consensus is yet to be established on the optimum margin necessary. Margenthaler et al. recently proposed the use of a "margin index," combining tumor size and margin status as a predictor of residual disease after BCS. We applied this new predictive tool to a population of patients with primary breast cancer who presented to a symptomatic breast unit to determine its suitability in predicting those who require reexcision surgery. METHODS: Retrospective analysis of our breast cancer database from January 1, 2000 to June 30, 2010 was performed, including all patients who underwent BCS. Of 531 patients who underwent BCS, 27.1% (144\\/531) required further reexcision procedures, and 55 were eligible for inclusion in the study. Margin index was calculated as: margin index = closest margin (mm)\\/tumor size (mm) × 100, with index >5 considered optimum. RESULTS: Of the 55 patients included, 31% (17\\/55) had residual disease. Fisher\\'s exact test showed margin index not to be a significant predictor of residual disease on reexcision specimen (P = 0.57). Of note, a significantly higher proportion of our patients presented with T2\\/3 tumors (60% vs. 38%). CONCLUSIONS: Although an apparently elegant tool for predicting residual disease after BCS, we have shown that it is not applicable to a symptomatic breast unit in Ireland.

Purpose: The purpose of this investigation was to characterize Merkel cell carcinomas (MCC) arisen in patients affected by autoimmune diseases and treated with biologic drugs. Experimental Design: Serum samples from patients with MCC were analyzed for the presence and titer of antibodies against antigens of the oncogenic Merkel cell polyomavirus (MCPyV). IgG antibodies against the viral oncoproteins large T (LT) and small T (ST) antigens and the viral capsid protein-1 were analyzed by indirect ELISA. Viral antigens were recombinant LT/ST and virus-like particles (VLP), respectively. MCPyV DNA sequences were studied using PCR methods in MCC tissues and in peripheral blood mononuclear cells (PBMC). Immunohistochemical (IHC) analyses were carried out in MCC tissues to reveal MCPyV LT oncoprotein. Results: MCPyV DNA sequences identified in MCC tissues showed 100% homology with the European MKL-1 strain. PBMCs from patients tested MCPyV-negative. Viral DNA loads in the three MCC tissues were in the 0.1 to 30 copy/cell range. IgG antibodies against LT/ST were detected in patients 1 and 3, whereas patient 2 did not react to the MCPyV LT/ST antigen. Sera from the three patients with MCC contained IgG antibodies against MCPyV VP1. MCC tissues tested MCPyV LT-antigen-positive in IHC assays, with strong LT expression with diffuse nuclear localization. Normal tissues tested MCPyV LT-negative when employed as control. Conclusions: We investigated three new MCCs in patients affected by rheumatologic diseases treated with biologic drugs, including TNF. A possible cause-effect relationship between pharmacologic immunosuppressive treatment and MCC onset is suggested. Indeed, MCC is associated with MCPyV LT oncoprotein activity.

Full Text Available Aspirin prevents cardiovascular disease and colon cancer; however aspirin's inhibition of platelet COX-1 only partially explains its diverse effects. We previously identified an aspirin response signature (ARS in blood consisting of 62 co-expressed transcripts that correlated with aspirin's effects on platelets and myocardial infarction (MI. Here we report that 60% of ARS transcripts are regulated by RUNX1 – a hematopoietic transcription factor - and 48% of ARS gene promoters contain a RUNX1 binding site. Megakaryocytic cells exposed to aspirin and its metabolite (salicylic acid, a weak COX-1 inhibitor showed up regulation in the RUNX1 P1 isoform and MYL9, which is transcriptionally regulated by RUNX1. In human subjects, RUNX1 P1 expression in blood and RUNX1-regulated platelet proteins, including MYL9, were aspirin-responsive and associated with platelet function. In cardiovascular disease patients RUNX1 P1 expression was associated with death or MI. RUNX1 acts as a tumor suppressor gene in gastrointestinal malignancies. We show that RUNX1 P1 expression is associated with colon cancer free survival suggesting a role for RUNX1 in aspirin's protective effect in colon cancer. Our studies reveal an effect of aspirin on RUNX1 and gene expression that may additionally explain aspirin's effects in cardiovascular disease and cancer.

Patient empowerment reflects the ability of patients to positively influence their health and health behavior such as physical activity. While interactive Web-based interventions are increasingly used in various chronic disease settings to enhance empowerment and physical activity, such interventions are still uncommon for cancer survivors. The objective of this study was to systematically review the literature regarding interactive Web-based interventions. We focused on interventions aimed at increasing patient empowerment and physical activity for various chronic conditions, and explored their possible relevance for cancer survivors. Searches were performed in PubMed, Embase, and Scopus to identify peer-reviewed papers reporting on randomized controlled trials that studied the effects of Web-based interventions. These interventions were developed for adults with diabetes, cardiovascular disease, chronic obstructive pulmonary disease, heart failure, or cancer. Intervention characteristics, effects on patient empowerment and physical activity, information on barriers to and facilitators of intervention use, users' experiences, and methodological quality were assessed. Results were summarized in a qualitative way. We used the recommendations of the Institute of Medicine (IOM) regarding cancer survivorship care to explore the relevance of the interventions for cancer survivors. We included 19 papers reporting on trials with 18 unique studies. Significant, positive effects on patient empowerment were reported by 4 studies and 2 studies reported positive effects on physical activity. The remaining studies yielded mixed results or no significant group differences in these outcomes (ie, no change or improvement for all groups). Although the content, duration, and frequency of interventions varied considerably across studies, commonly used elements included education, self-monitoring, feedback/tailored information, self-management training, personal exercise program, and

During cancer treatment children have reduced contact with their social network of friends, and have limited participation in education, sports, and leisure activities. During and following cancer treatment, children describe school related problems, reduced physical fitness, and problems related to interaction with peers. The RESPECT study is a nationwide population-based prospective, controlled, mixed-methods intervention study looking at children aged 6-18 years newly diagnosed with cancer in eastern Denmark (n=120) and a matched control group in western Denmark (n=120). RESPECT includes Danish-speaking children diagnosed with cancer and treated at pediatric oncology units in Denmark. Primary endpoints are the level of educational achievement one year after the cessation of first-line cancer therapy, and the value of VO2max one year after the cessation of first-line cancer therapy. Secondary endpoints are quality of life measured by validated questionnaires and interviews, and physical performance. RESPECT includes a multimodal intervention program, including ambassador-facilitated educational, physical, and social interventions. The educational intervention includes an educational program aimed at the child with cancer, the child's schoolteachers and classmates, and the child's parents. Children with cancer will each have two ambassadors assigned from their class. The ambassadors visit the child with cancer at the hospital at alternating 2-week intervals and participate in the intervention program. The physical and social intervention examines the effect of early, structured, individualized, and continuous physical activity from diagnosis throughout the treatment period. The patients are tested at diagnosis, at 3 and 6 months after diagnosis, and one year after the cessation of treatment. The study is powered to quantify the impact of the combined educational, physical, and social intervention programs. RESPECT is the first population-based study to examine the

compared to 0% for patients with N1 - N3 disease (P < 0.0001). An analysis of high risk patients (30) with T3-T4 or N1 - N3 disease revealed at 5 years on OS of 9%, a DFS of 10%, a PC rate of 26% and FFDF of 20%. In this subset of patients, there was a trend toward improved pelvic control in patients receiving radiation therapy (14) with a 5 year PC of 60% compared to a rate of 23% for those patients not irradiated (16) (p=0.59). Acute complications (grade 3 or >) were noted in 3 patients (20%) receiving radiation therapy and these included two cases of grade 3 skin reactions and one case of grade 4 gastro-intestinal toxicity. Two patients (13%) developed small bowel obstruction at 2 and 4 months, respectively, post-irradiation which were managed conservatively. There were no long term complications in patients irradiated. CONCLUSION: Treatment results are comparable to those historically reported for non-inflammatory bowel disease related rectal cancer although the subset of high risk patients appeared to have a poorer outcome. In light of this finding and the ability of patients with inflammatory bowel disease to tolerate pelvic irradiation, high risk patients should be treated aggressively with chemotherapy and radiation therapy.

The association between Parkinson's disease (PD) and prostate cancer, both common in elderly men, is disputable. In the STRIDE-PD study, prostate cancer developed in 9 patients (3.7%) receiving levodopa/carbidopa with entacapone, a catechol-O-methyltransferase inhibitor, versus 2 cases (0.9%) without entacapone. The current pharmacoepidemiological study aimed to determine whether entacapone increases prostate cancer incidence or mortality in PD patients and whether cumulative exposure affects these rates. We performed a retrospective cohort study using population-wide health care registers with patient-level linkage. Prostate cancer incidence and mortality were modeled by Cox's proportional hazards models. Use of entacapone with l-dopa/dopa decarboxylase inhibitor caused no increased risk of prostate cancer incidence (hazard ratio [HR]: 1.05; 95% confidence interval: 0.76-1.44) or mortality (0.93; 0.43-1.98). The HR for cumulative entacapone use of >360 days versus never-use was 0.82 (0.56-1.18) for prostate cancer incidence and 1.27 (0.60-2.72) for prostate cancer mortality. © 2015 International Parkinson and Movement Disorder Society.

It is unknown whether cancer patients with different life expectancies have different attitudes and emotions toward death and an afterlife. Also, it is unclear whether these attitudes and emotions toward death and afterlife influence patients' distress. To assess the relationship of attitudes and emotions towards death and an afterlife with quality of life, depression and hopelessness in cancer patients without evidence of disease and advanced cancer patients facing death. Ninety-one cancer patients without evidence of disease and 57 advanced cancer patients completed the Dutch Attitudes Toward Death and Afterlife Scale. Emotions toward death were measured using the Self-Confrontation Method. Quality of life was measured with the Satisfaction with Life Scale and the European Organization for Research and Treatment of Cancer (EORTC) Quality-of-Life Questionnaire. Depression and hopelessness were measured with the Beck Depression Inventory for Primary Care and the Beck Hopelessness Scale. Average scores on attitudes and emotions toward death and an afterlife were not significantly different between the two groups. However, in the no evidence of disease group, a negative association between negative emotions and social functioning was observed, which was not present in the advanced cancer group. In the advanced cancer group, associations were observed that were not present in the no evidence of disease group: positive associations between an explicitly religious attitude and global health status and between reincarnation belief and role and cognitive functioning, and a negative association between other-directed emotions and social functioning. Patients without evidence of disease and advanced cancer patients do not differ in attitudes or emotions toward death, but the relationship between these attitudes and emotions and aspects of quality of life varies. When there is no evidence of disease, negative emotions play the most important role, whereas in the advanced

A total of 2144 head and neck cancers were treated by radiotherapy at the National Sapporo Hospital between 1974 and 2001. Of these, 313 (14.6%) were found to have other primary cancers besides head and neck cancer, in which double cancers were 79% and triple or more cancers were 21%. Frequency according to primary site of the first head and neck cancer was oral cavity: 107/603 (17.7%), epipharynx cancer: 7/117 (6.0%), oropharyngeal cancer: 63/257 (24.5%), hypopharyngeal cancer: 65/200 (32.5%), laryngeal cancer: 114/558 (20.4%), and nose/paranasal sinus: 4.9% respectively. Esophageal cancer, head and neck cancer, lung cancer and gastric cancer were very frequent as other primary sites combined with the head and neck. The first onset region was the head and neck in 233 out of 313 cases with multiple primary cancers. The five-year survival rate from the onset of head and neck cancers is 52%, 10-year: 30%, and 5-year cause-specific survival rate 82%, and 10-year: 78%, respectively. The treatment possibilities in multiple primary cancers tend to be limited because the treatment areas are sometimes overlapped. New approaches to the treatment of multiple primary cancers should be considered in the future. (author)

: Attitudes toward guilt and forgiveness may be important factors determining distress in cancer patients. Direct comparative studies in patients with different life expectancies exploring attitudes toward guilt and forgiveness are lacking. Also, sociodemographic and religious characteristics determining the attitudes toward guilt and forgiveness are unknown. : The objective of this study was to compare attitudes toward guilt and forgiveness in cancer patients without evidence of disease and advanced cancer patients. : A descriptive research design was used. Ninety-seven patients without evidence of disease and 55 advanced cancer patients filled out the Dutch Guilt Measurement Instrument and the Forgiveness of Others Scale. : Both groups had an attitude of nonreligious guilt and forgiveness, but not of religious guilt. No significant differences in attitudes toward guilt and forgiveness were observed between the 2 groups. In contrast to sociodemographic characteristics, religious characteristics were relevant predictors for guilt and forgiveness. Significant differences in relations between images of God and attitudes toward guilt were observed between the 2 patient groups. : An attitude of nonreligious guilt and forgiveness was found in cancer patients, irrespective of the stage of disease. Religious characteristics were significantly associated with attitudes of guilt and forgiveness. This correlation differed in the early and the advanced setting of disease. : The observed relations between religious characteristics and attitudes of guilt and forgiveness suggest that a careful examination of the role of religious beliefs and values is relevant in the clinical care of patients with cancer, both in the setting of early and advanced disease.

Histones and their modifications in ovarian cancer – drivers of disease and therapeutic targets

Full Text Available Epithelial ovarian cancer has the highest mortality of the gynecological malignancies. High grade serous epithelial ovarian cancer (SEOC is the most common subtype, with the majority of women presenting with advanced disease where 5 year survival is around 25%. Platinum-based chemotherapy in combination with paclitaxel remains the most effective treatment despite platinum therapies being introduced almost 40 years ago. Advances in molecular medicine are underpinning new strategies for the treatment of cancer. Major advances have been made by international initiatives to sequence cancer genomes. For SEOC, with the exception of TP53 that is mutated in virtually 100% of these tumors, there is no other gene mutated at high frequency. There is extensive copy number variation, as well as changes in methylation patterns that will influence gene expression. To date, the role of histones and their post-translational modifications in ovarian cancer is a relatively understudied field. Post-translational histone modifications play major roles in gene expression as they direct the configuration of chromatin and so access by transcription factors. Histone modifications include methylation, acetylation and monoubiquitination, with involvement of enzymes including histone methyl transferases (HMTases, histone acetyltransferases/deacetylases and ubiquitin ligases/deubiquitinases respectively. Complexes such as the Polycomb Repressive Complex also play roles in the control of histone modifications and more recently roles for long non-coding (lnc RNA and microRNAs (miRNAs are emerging. Epigenomic-based therapies targeting histone modifications are being developed and offer new approaches for the treatment of ovarian cancer. Here we discuss histone modifications and their aberrant regulation in malignancy and specifically in ovarian cancer. We review current and upcoming histone-based therapies that have the potential to inform and improve treatment strategies for

Radioiodine (RAI) is a cornerstone in the treatment of Differentiated Thyroid Cancer (DTC). In patients on haemodialysis due to End-Stage Renal Disease (ESRD), it must be used cautiously, considering the renal clearance of this radionuclide. Also, the safety of the procedure and subsequent long-term outcome is still not well defined. In 2001, we described a dosimetric method and short-term results in three patients, with a good safety profile. We hypothesize that our method is safe in a long-term scenario without compromising the prognosis of both renal and thyroid disease. Descriptive-retrospective study. A systematic search was carried out using our clinical database from 2000 to 2014. DTC and radioiodine treatment while on haemodialysis. peritoneal dialysis.

The prognosis of advanced (stage IV) cancer of the digestive organs is very poor. We have previously reported a case of advanced breast cancer with bone metastasis that was successfully treated with combined treatments including autologous formalin-fixed tumor vaccine (AFTV). Herein, we report the success of this approach in advanced stage IV (heavily metastasized) cases of gall bladder cancer and colon cancer. Case 1: A 61-year-old woman with stage IV gall bladder cancer (liver metastasis and lymph node metastasis) underwent surgery in May 2011, including partial resection of the liver. She was treated with AFTV as the first-line adjuvant therapy, followed by conventional chemotherapy. This patient is still alive without any recurrence, as confirmed with computed tomography, for more than 5 years. Case 2: A 64-year-old man with stage IV colon cancer (multiple para-aortic lymph node metastases and direct abdominal wall invasion) underwent non-curative surgery in May 2006. Following conventional chemotherapy, two courses of AFTV and radiation therapy were administered sequentially. This patient has had no recurrence for more than 5 years. We report the success of combination therapy including AFTV in cases of liver-metastasized gall bladder cancer and abdominal wall-metastasized colon cancer. Both patients experienced long-lasting, complete remission. Therefore, combination therapies including AFTV should be considered in patients with advanced cancer of the digestive organs.

Full Text Available This large-scale, controlled cohort study estimated the risks of lung cancer in patients with gastro-esophageal reflux disease (GERD in Taiwan. We conducted this population-based study using data from the National Health Insurance Research Database of Taiwan during the period from 1997 to 2010. Patients with GERD were diagnosed using endoscopy, and controls were matched to patients with GERD at a ratio of 1:4. We identified 15,412 patients with GERD and 60,957 controls. Compared with the controls, the patients with GERD had higher rates of osteoporosis, diabetes mellitus, asthma, chronic obstructive pulmonary disease, pneumonia, bronchiectasis, depression, anxiety, hypertension, dyslipidemia, chronic liver disease, congestive heart failure, atrial fibrillation, stroke, chronic kidney disease, and coronary artery disease (all P < .05. A total of 85 patients had lung cancer among patients with GERD during the follow-up of 42,555 person-years, and the rate of lung cancer was 0.0020 per person-year. By contrast, 232 patients had lung cancer among patients without GERD during the follow-up of 175,319 person-years, and the rate of lung cancer was 0.0013 per person-year. By using stepwise Cox regression model, the overall incidence of lung cancer remained significantly higher in the patients with GERD than in the controls (hazard ratio, 1.53; 95% CI [1.19–1.98]. The cumulative incidence of lung cancer was higher in the patients with GERD than in the controls (P = .0012. In conclusion, our large population-based cohort study provides evidence that GERD may increase the risk of lung cancer in Asians.

Whole body (WB) magnetic resonance imaging (MRI), including diffusion-weighted imaging (DWI) has become increasingly utilized in cancer imaging, yet the clinical utility of these techniques in follow-up of testicular cancer patients has not been evaluated. The purpose of this study was to evaluate the feasibility of WB MRI with continuous table movement (CTM) technique, including multistep DWI in follow-up of patients with testicular cancer. WB MRI including DWI was performed in follow-up of 71 consecutive patients (median age, 37 years; range 19-84) with histologically confirmed testicular cancer. WB MRI protocol included axial T1-Dixon and T2-BLADE sequences using CTM technique. Furthermore, multi-step DWI was performed using b-value 50 and 1000 s/mm(2). One criterion for feasibility was patient tolerance and satisfactory image quality. Another criterion was the accuracy in detection of any pathological mass, compared to standard of reference. Signal intensity in DWI was used for evaluation of residual mass activity. Clinical, laboratory and imaging follow-up were applied as standard of reference for the evaluation of WB MRI. WB MRI was tolerated in nearly all patients (69/71 patients, 97%) and the image quality was satisfactory. Metal artifacts deteriorated the image quality in six patients, but it did not influence the overall results. No case of clinical relapse was observed during the follow-up time. There was a good agreement between conventional WB MRI and standard of reference in all patients. Three patients showed residual masses and DWI signal was not restricted in these patients. Furthermore, DWI showed abnormally high signal intensity in a normal-sized retroperitoneal lymph node indicating metastasis. The subsequent (18)F-FDG PET/CT could verify the finding. WB MRI with CTM technique including multi-step DWI is feasible in follow-up of patients with testicular cancer. DWI may contribute to important added-value data to conventional MRI sequences

To evaluate preoperative serum levels of Ca125 and Tag72-4 tumour markers and investigate if abnormal levels correlate to mortality and disease-free survival. Retrospective observational study of a cohort of 282 women (mean age 62.3, SD 10.5 years) with primary endometrial cancer included all consecutive cases treated in a tertiary Gynaecological oncology Center. Excluded cases with other cancer or previous cancer treatment, major abdominal pathology or inflammation, endometriosis. Preoperative serum Tag72 and Ca125 levels were determined and evaluated in relation to disease-free survival (DFS) and disease-specific overall survival (DOS). Raised Ca125 correlates to worse overall disease-specific survival (66.1 vs 87.8 months, p = 0.021) and Tag72 correlates to shorter disease-free survival (69.2 vs 67.3 months, p = 0.021) and higher recurrence rate (13.5 vs 6 %, p = 0.021). When both Ca125 and Tag72 are abnormal DFS and DOS are worse. 93.3 % (72.3 months) vs 82.4 %, (61.3 months) p = 0.018 and 96.3 % (74.8 months) vs 88.2 %, (65.9 months) p = 0.021, respectively. This study enhances the value of preoperative tumour markers and their prognostic value. Ca125 and Tag72 appear to be good predictors of poor prognosis in patients with endometrial cancer.

Psychosocial intervention effects on adaptation, disease course and biobehavioral processes in cancer.

Science.gov (United States)

Antoni, Michael H

2013-03-01

A diagnosis of cancer and subsequent treatments place demands on psychological adaptation. Behavioral research suggests the importance of cognitive, behavioral, and social factors in facilitating adaptation during active treatment and throughout cancer survivorship, which forms the rationale for the use of many psychosocial interventions in cancer patients. This cancer experience may also affect physiological adaptation systems (e.g., neuroendocrine) in parallel with psychological adaptation changes (negative affect). Changes in adaptation may alter tumor growth-promoting processes (increased angiogenesis, migration and invasion, and inflammation) and tumor defense processes (decreased cellular immunity) relevant for cancer progression and the quality of life of cancer patients. Some evidence suggests that psychosocial intervention can improve psychological and physiological adaptation indicators in cancer patients. However, less is known about whether these interventions can influence tumor activity and tumor growth-promoting processes and whether changes in these processes could explain the psychosocial intervention effects on recurrence and survival documented to date. Documenting that psychosocial interventions can modulate molecular activities (e.g., transcriptional indicators of cell signaling) that govern tumor promoting and tumor defense processes on the one hand, and clinical disease course on the other is a key challenge for biobehavioral oncology research. This mini-review will summarize current knowledge on psychological and physiological adaptation processes affected throughout the stress of the cancer experience, and the effects of psychosocial interventions on psychological adaptation, cancer disease progression, and changes in stress-related biobehavioral processes that may mediate intervention effects on clinical cancer outcomes. Very recent intervention work in breast cancer will be used to illuminate emerging trends in molecular probes of

Increasingly, countries have introduced female vaccination against human papillomavirus (HPV), causally linked to several cancers and genital warts, but few have recommended vaccination of boys. Declining vaccine prices and strong evidence of vaccine impact on reducing HPV-related conditions in both women and men prompt countries to reevaluate whether HPV vaccination of boys is warranted. A previously-published dynamic model of HPV transmission was empirically calibrated to Norway. Reductions in the incidence of HPV, including both direct and indirect benefits, were applied to a natural history model of cervical cancer, and to incidence-based models for other non-cervical HPV-related diseases. We calculated the health outcomes and costs of the different HPV-related conditions under a gender-neutral vaccination program compared to a female-only program. Vaccine price had a decisive impact on results. For example, assuming 71% coverage, high vaccine efficacy and a reasonable vaccine tender price of $75 per dose, we found vaccinating both girls and boys fell below a commonly cited cost-effectiveness threshold in Norway ($83,000/quality-adjusted life year (QALY) gained) when including vaccine benefit for all HPV-related diseases. However, at the current market price, including boys would not be considered 'good value for money.' For settings with a lower cost-effectiveness threshold ($30,000/QALY), it would not be considered cost-effective to expand the current program to include boys, unless the vaccine price was less than $36/dose. Increasing vaccination coverage to 90% among girls was more effective and less costly than the benefits achieved by vaccinating both genders with 71% coverage. At the anticipated tender price, expanding the HPV vaccination program to boys may be cost-effective and may warrant a change in the current female-only vaccination policy in Norway. However, increasing coverage in girls is uniformly more effective and cost-effective than expanding

Declining vaccine prices and strong evidence of vaccine impact on reducing HPV-related conditions in both women and men prompt countries to reevaluate whether HPV vaccination of boys is warranted. Methods A previously-published dynamic model of HPV transmission was empirically calibrated to Norway. Reductions in the incidence of HPV, including both direct and indirect benefits, were applied to a natural history model of cervical cancer, and to incidence-based models for other non-cervical HPV-related diseases. We calculated the health outcomes and costs of the different HPV-related conditions under a gender-neutral vaccination program compared to a female-only program. Results Vaccine price had a decisive impact on results. For example, assuming 71% coverage, high vaccine efficacy and a reasonable vaccine tender price of $75 per dose, we found vaccinating both girls and boys fell below a commonly cited cost-effectiveness threshold in Norway ($83,000/quality-adjusted life year (QALY) gained) when including vaccine benefit for all HPV-related diseases. However, at the current market price, including boys would not be considered ‘good value for money.’ For settings with a lower cost-effectiveness threshold ($30,000/QALY), it would not be considered cost-effective to expand the current program to include boys, unless the vaccine price was less than $36/dose. Increasing vaccination coverage to 90% among girls was more effective and less costly than the benefits achieved by vaccinating both genders with 71% coverage. Conclusions At the anticipated tender price, expanding the HPV vaccination program to boys may be cost-effective and may warrant a change in the current female-only vaccination policy in Norway. However, increasing coverage in girls is uniformly more

Ethnic minority groups including Asians in Canada have different knowledge and perceptions of heart disease and breast cancer compared with the ethnic majority group. Examine relationships between perceptions of heart disease and breast cancer, and lifestyle behaviors for Canadian women with British and with South Asian ancestry. Women with South Asian ( n = 170) and with British ( n = 373) ancestry ( M age = 33.01, SD = 12.86) reported leisure time physical activity, intended fruit and vegetable consumption, disease perceptions (ability to reduce risk, control over getting the diseases, and influence of family history), and demographic information. Mann-Whitney tests and multiple hierarchical linear regressions were used to examine the relationships between lifestyle behaviors and disease perceptions, with ancestry explored as a possible moderator. Participants with South Asian ancestry believed they had greater ability to reduce their risk and have control over getting breast cancer than participants with British ancestry. Family history influences on getting either disease was perceived as higher for women with British ancestry. Age was positively related to all three perceptions in both diseases. Intended fruit and vegetable consumption was positively related to perceptions of ability to reduce risk and control of both diseases, but was stronger for women with South Asian ancestry regarding perceptions of breast cancer. Leisure time physical activity was positively related to perceptions of control over getting heart disease for women with British ancestry. Women's disease perceptions can vary by ancestry and lifestyle behaviors. Accurate representation of diseases is essential in promoting effective preventative behaviors.

Physiological and cellular functions operate in a 24-hour cyclical pattern orchestrated by an endogenous process known as the circadian rhythm. Circadian rhythms represent intrinsic oscillations of biological functions that allow for adaptation to cyclic environmental changes. Key clock genes that affect the persistence and periodicity of circadian rhythms include BMAL1/CLOCK, Period 1, Period 2, and Cryptochrome. Remarkable progress has been made in our understanding of circadian rhythms and their role in common medical conditions. A critical review of the literature supports the association between circadian misalignment and adverse health consequences in sepsis, obstructive lung disease, obstructive sleep apnea, and malignancy. Circadian misalignment plays an important role in these disease processes and can affect disease severity, treatment response, and survivorship. Normal inflammatory response to acute infections, airway resistance, upper airway collapsibility, and mitosis regulation follows a robust circadian pattern. Disruption of normal circadian rhythm at the molecular level affects severity of inflammation in sepsis, contributes to inflammatory responses in obstructive lung diseases, affects apnea length in obstructive sleep apnea, and increases risk for cancer. Chronotherapy is an underused practice of delivering therapy at optimal times to maximize efficacy and minimize toxicity. This approach has been shown to be advantageous in asthma and cancer management. In asthma, appropriate timing of medication administration improves treatment effectiveness. Properly timed chemotherapy may reduce treatment toxicities and maximize efficacy. Future research should focus on circadian rhythm disorders, role of circadian rhythm in other diseases, and modalities to restore and prevent circadian disruption.

To investigate the relationship between obesity and disease-free survival (DFS) and overall survival (OS) of triple-negative breast cancer. Citations were searched in PubMed, Cochrane Library, and Web of Science. Random effect model meta-analysis was conducted by using Revman software version 5.0, and publication bias was evaluated by creating Egger regression with STATA software version 12. Nine studies (4412 patients) were included for DFS meta-analysis, 8 studies (4392 patients) include for OS meta-analysis. There were no statistical significances between obesity with DFS (P = .60) and OS (P = .71) in triple-negative breast cancer (TNBC) patients. Obesity has no impact on DFS and OS in patients with TNBC.

Head and neck cancer of unknown primary (HNCUP) is rare and prospective studies are lacking. The impact of different prognostic factors such as age and N stage is not completely known, the optimal treatment is not yet established, and the reported survival rates vary. In the last decade, human papilloma virus (HPV) has been identified as a common cause of and important prognostic factor in oropharyngeal cancer, and there is now growing interest in the importance of HPV for HNCUP. The aim of the present study on curatively treated HNCUP was to investigate the prognostic importance of different factors, including HPV status, treatment, and overall survival. A search for HNCUP was performed in the Swedish Cancer Registry, Western health district, between the years 1992-2009. The medical records were reviewed, and only patients with squamous cell carcinoma or undifferentiated carcinoma treated with curative intent were included. The tumor specimens were retrospectively analyzed for HPV with p16 immunostaining. Sixty-eight patients were included. The mean age was 59 years. The majority were males, and had N2 tumors. Sixty-nine percent of the tumors were HPV positive using p16 staining. Patients who were older than 70 years, patients with N3-stage tumors, and patients with tumors that were p16 negative had a significantly worse prognosis. The overall 5-year survival rate for patients with p16-positive tumors was 88% vs 61% for p16-negative tumors. Treatment with neck dissection and postoperative radiation or (chemo) radiation had 81 and 88% 5-year survival rates, respectively. The overall and disease-free 5-year survival rates for all patients in the study were 82 and 74%. Curatively treated HNCUP had good survival. HPV infection was common. Independent prognostic factors for survival were age over 70 years, HPV status and N3 stage. We recommend that HPV analysis should be performed routinely for HNCUP. Treatment with neck dissection and postoperative radiation or

The purpose of this study was to assess the cardiac side effects, primarily the occurrence of ischemic heart disease, in symptom-free patients with early breast cancer treated with radiotherapy. Thirty-seven survivors of a former randomized study of early breast cancer were examined. Twenty patients irradiated pre- or postoperatively for left sided disease (study group patients) were compared with 17 controls who were either treated for right sided disease, or were nonirradiated patients. Radiotherapy was randomized in the original study; either tangential field 60 Co, or electron-therapy was delivered. Echocardiography and bicycle ergometry stress test with 99m Tc SestaMIBI myocardial perfusion scintigraphy were carried out and the patients' major risk factors for ischemic heart disease were also listed. Our results showed a significant difference between the scintigraphic findings of the two groups. Five of the 20 study group patients (25%), while none of the 17 controls exhibited some kind of significant defects on scintigraphy, indicating ischemic heart disease (p < 0.05). No deterioration in left ventricular systolic and/or diastolic function could be detected by echocardiography. Radiotherapy for left sided breast cancer with the mentioned treatment technique may present as an independent risk factor in the long-term development of ischemic heart disease, while left ventricular dysfunction could not be related to the previous irradiation. The authors emphasize the need to optimize adjuvant radiotherapy for early breast cancer by considering the dose both to the heart as well as the cancer. 39 refs., 4 tabs

Dose-response relationship analysis for cancer and circulatory system disease mortality risks among uranium miners

The relation between lung cancer risk and radon exposure has been clearly established, especially from the studies on uranium miner cohorts. But the association between radon exposure and extrapulmonary cancers and non-cancer diseases remains not well known. Moreover, the health risks associated with the other mining-related ionizing radiation exposures are still under consideration. The aim of this thesis is to contribute to the estimation of the radio-induced health risks at low-doses through the analysis of the kidney cancer and Circulatory System Disease (CSD) mortality risks among uranium miners. Kidney cancer mortality risk analyses were performed from the French cohort of uranium miners (n=5086; follow-up period: 1946-2007), the post-55 cohort (n=3,377; follow-up period: 1957-2007) and the German cohort of the Wismut (n=58,986; follow-up period: 1946-2003) which included 24, 11 and 174 deaths from kidney cancer, respectively. The exposures to radon and its short-lived progeny (expressed in Working Level Month WLM), to uranium ore dust (kBqh.m -3 ) and to external gamma rays (mSv) were estimated for each miners and the equivalent kidney dose was calculated. The dose-response relation was refined considering two responses: the instantaneous risk of kidney cancer mortality (corresponding to the classical analysis, Cause specific Hazard Ratio (CSHR) estimated with the Cox model) and its occurrence probability during the followup (Sub-distribution Hazard Ratio (SHR) estimated with the Fine and Gray model). An excess of kidney cancer mortality was observed only in the French cohort (SMR = 1.62 CI95%[1.04; 2.41]). In the Wismut cohort, a decrease of the kidney cancer mortality was observed (0.89 [0.78; 0.99]). For these three cohorts, the occupational radiological exposures (or the equivalent kidney dose) were significantly associated neither with the risk of kidney cancer mortality (e.g. CSHRWismut-radon/100 WLM=1.023 [0.993; 1.053]), nor with its occurrence

We propose a strategic, computer based, prostate cancer decision making model based on the analytic hierarchy process. We developed a model that improves physician-patient joint decision making and enhances the treatment selection process by making this critical decision rational and evidence based. Two groups (patient and physician-expert) completed a clinical study comparing an initial disease management choice with the highest ranked option generated by the computer model. Participants made pairwise comparisons to derive priorities for the objectives and subobjectives related to the disease management decision. The weighted comparisons were then applied to treatment options to yield prioritized rank lists that reflect the likelihood that a given alternative will achieve the participant treatment goal. Aggregate data were evaluated by inconsistency ratio analysis and sensitivity analysis, which assessed the influence of individual objectives and subobjectives on the final rank list of treatment options. Inconsistency ratios less than 0.05 were reliably generated, indicating that judgments made within the model were mathematically rational. The aggregate prioritized list of treatment options was tabulated for the patient and physician groups with similar outcomes for the 2 groups. Analysis of the major defining objectives in the treatment selection decision demonstrated the same rank order for the patient and physician groups with cure, survival and quality of life being more important than controlling cancer, preventing major complications of treatment, preventing blood transfusion complications and limiting treatment cost. Analysis of subobjectives, including quality of life and sexual dysfunction, produced similar priority rankings for the patient and physician groups. Concordance between initial treatment choice and the highest weighted model option differed between the groups with the patient group having 59% concordance and the physician group having only 42

Approximately 90% of the world population is infected by Epstein-Barr virus (EBV). Usually, it infects B lymphocytes, predisposing them to malignant transformation. Infection of epithelial cells occurs rarely, and it is estimated that about to 10% of gastric cancer patients harbor EBV in their malignant cells. Given that gastric cancer is the third leading cause of cancer-related mortality worldwide, with a global annual incidence of over 950,000 cases, EBV-positive gastric cancer is the largest group of EBV-associated malignancies. Based on gene expression profile studies, gastric cancer was recently categorized into four subtypes; EBV-positive, microsatellite unstable, genomically stable and chromosomal instability. Together with previous studies, this report provided a more detailed molecular characterization of gastric cancer, demonstrating that EBV-positive gastric cancer is a distinct molecular subtype of the disease, with unique genetic and epigenetic abnormalities, reflected in a specific phenotype. The recognition of characteristic molecular alterations in gastric cancer allows the identification of molecular pathways involved in cell proliferation and survival, with the potential to identify therapeutic targets. These findings highlight the enormous heterogeneity of gastric cancer, and the complex interplay between genetic and epigenetic alterations in the disease, and provide a roadmap to implementation of genome-guided personalized therapy in gastric cancer. The present review discusses the initial studies describing EBV-positive gastric cancer as a distinct clinical entity, presents recently described genetic and epigenetic alterations, and considers potential therapeutic insights derived from the recognition of this new molecular subtype of gastric adenocarcinoma.

Full Text Available The incidence of esophageal cancer is rapidly increasing especially in developing countries. The major risk factors include unhealthy lifestyle practices such as alcohol consumption, smoking, and chewing tobacco to name a few. Diagnosis at an advanced stage and poor prognosis make esophageal cancer one of the most lethal diseases. These factors have urged further research in understanding the pathophysiology of the disease. Animal models not only aid in understanding the molecular pathogenesis of esophageal cancer but also help in developing therapeutic interventions for the disease. This review throws light on the various recent laboratory animal models for esophageal cancer.

Guanine holes are prominent targets for mutation in cancer and inherited disease.

Directory of Open Access Journals (Sweden)

Albino Bacolla

Full Text Available Single base substitutions constitute the most frequent type of human gene mutation and are a leading cause of cancer and inherited disease. These alterations occur non-randomly in DNA, being strongly influenced by the local nucleotide sequence context. However, the molecular mechanisms underlying such sequence context-dependent mutagenesis are not fully understood. Using bioinformatics, computational and molecular modeling analyses, we have determined the frequencies of mutation at G • C bp in the context of all 64 5'-NGNN-3' motifs that contain the mutation at the second position. Twenty-four datasets were employed, comprising >530,000 somatic single base substitutions from 21 cancer genomes, >77,000 germline single-base substitutions causing or associated with human inherited disease and 16.7 million benign germline single-nucleotide variants. In several cancer types, the number of mutated motifs correlated both with the free energies of base stacking and the energies required for abstracting an electron from the target guanines (ionization potentials. Similar correlations were also evident for the pathological missense and nonsense germline mutations, but only when the target guanines were located on the non-transcribed DNA strand. Likewise, pathogenic splicing mutations predominantly affected positions in which a purine was located on the non-transcribed DNA strand. Novel candidate driver mutations and tissue-specific mutational patterns were also identified in the cancer datasets. We conclude that electron transfer reactions within the DNA molecule contribute to sequence context-dependent mutagenesis, involving both somatic driver and passenger mutations in cancer, as well as germline alterations causing or associated with inherited disease.

The proportion of lung cancers with an occupational origin has been estimated to be between 10 and 20%. They are largely under-reported, as 60% are not compensated as occupational disease. Although most patients are not familiar with the process of compensation, other factors could explain this under-reporting. The aim of this study was to identify psychosocial factors that could impact patients with occupational lung cancer to claim for compensation. We conducted a case study involving semi-structured interviews with eight lung cancer patients enrolled in a cohort designed to systematically screen occupational exposures and propose claims for compensation to work-related cancer patients. Seven interviewed patients were familiar with occupational cancers, but most of them did not believe that past exposure could be related to their current disease. Patients associated compensation claims with a long and complex procedure for an abstract purpose. Several patients expressed a certain attachment to their employers. Interviewed patients often considered compensation claims to be a grievance procedure against the employers whom they did not consider to be responsible for their disease. Lung cancer is itself an obstacle to compensation considering the aggressive treatments and related adverse events, the poor medium-term prognosis and the predominant role of smoking in the etiology of the disease. Patients mentioned the financial compensation and the role of healthcare professionals as key elements to motivate them to claim for compensation.

Schistosomiasis and Cancer

Full Text Available Schistosomiasis is not known to be associated with any malignant disease other than bladder cancer. Bladder cancer is still the most common malignant tumor among males in Egypt and some African and Middle East countries. However, the frequency rate of bladder cancer has declined significantly during the last 25 years. This drop is mainly related to the control of Schistosomiasis. Many studies have elucidated the pathogenic events of Schistosomal-related bladder cancer with a suggested theory of pathogenesis. Furthermore, the disease presents with a distinct clinicopathologic profile that is quite different from bladder cancer elsewhere with younger age at presentation, more male predominance, more invasive stages, and occurrence of squamous cell carcinoma pathologic subtype. However, recent data suggest that this profile has been dramatically changed over the past 25 years leading to minimization of the differences between its features in Egypt and that in Western countries. Management of muscle-invasive localized disease is mainly surgery with 5-year survival rates of 30–50%. Although still a debatable issue, adjuvant and neoadjuvant chemotherapy and radiotherapy have improved treatment outcomes including survival and bladder preservation rates in most studies. This controversy emphasizes the need of individualized treatment options based on a prognostic index or other factors that can define the higher risk groups where more aggressive therapy is needed. The treatment for locally advanced and/or metastatic disease has passed through a series of clinical trials since 1970s. These phase II and III trials have included the use of single agent and combination of chemotherapy and radiotherapy regimens. The current standard of systemic chemotherapy of generally fit patients is now the gemcitabine–cisplatin combination. In conclusion, a changing pattern of bladder cancer in Egypt is clearly observed. This is mainly due to the success in the

Full Text Available Purpose. The prognostic role of serum cancer antigen 15-3 (CA15-3 and carcinoembryonic antigen (CEA in breast cancer remains controversial. In this study, we conducted a meta-analysis to investigate the prognostic value of these two markers in breast cancer patients. Methods. After electronic databases were searched, 36 studies (31 including information regarding CA15-3 and 23 including information regarding CEA with 12,993 subjects were included. Based on the data directly or indirectly from the available studies, the hazard ratios (HRs and odds ratios (ORs and their 95% confidence intervals (CIs were pooled according to higher or lower marker levels. Results. Elevated CA15-3 or CEA was statistically significant with poorer DFS and OS in breast cancer (multivariate analysis of OS: HR = 2.03, 95% CI 1.76–2.33 for CA15-3; HR = 1.79, 95% CI 1.46–2.20 for CEA; multivariate analysis of DFS: HR = 1.56, 95% CI 1.06–1.55 for CA15-3; HR = 1.77, 95% CI 1.53–2.04 for CEA. Subgroup analysis showed that CA15-3 or CEA had significant predictive values in primary or metastasis types and different cut-offs and included sample sizes and even the study publication year. Furthermore, elevated CA15-3 was associated with advanced histological grade and younger age, while elevated CEA was related to the non-triple-negative tumor type and older age. These two elevated markers were all associated with a higher tumor burden. Conclusions. This meta-analysis showed that elevated serum CA15-3 or CEA was associated with poor DFS and OS in patients with breast cancer, and they should be tested anytime if possible.

Unexpected relevance of the hallmarks of cancer to the pathogenesis of polycystic kidney disease

2018-01-01

Autosomal dominant polycystic kidney disease (ADPKD) is a progressive inherited disorder in which renal tissue is gradually replaced with fluid-filled cysts, giving rise to chronic kidney disease (CKD) and progressive loss of renal function. ADPKD is also associated with liver ductal cysts, hypertension, chronic pain and extrarenal problems such as cerebral aneurysms. Intriguingly, improved understanding of the signalling and pathological derangements characteristic of ADPKD has revealed marked similarities to those of solid tumours, even though the gross presentation of tumours and the greater morbidity and mortality associated with tumour invasion and metastasis would initially suggest an entirely different disease processes. The commonalities between ADPKD and cancer are provocative, particularly in the context of recent preclinical and clinical studies of ADPKD that have shown promise with drugs that were originally developed for cancer. The potential therapeutic benefit of such repurposing has led us to review in detail the pathological features of ADPKD through the lens of the defined, classic hallmarks of cancer. In addition, we have evaluated features typical of ADPKD, and determined whether evidence supports the presence of such features in cancer cells. This analysis, which places pathological processes in the context of defined signalling pathways and approved signalling inhibitors, highlights potential avenues for further research and therapeutic exploitation in both diseases.

Janus-Faced Myeloid-Derived Suppressor Cell Exosomes for the Good and the Bad in Cancer and Autoimmune Disease

Directory of Open Access Journals (Sweden)

Margot Zöller

2018-02-01

Full Text Available Myeloid-derived suppressor cells (MDSCs are a heterogeneous population of immature myeloid cells originally described to hamper immune responses in chronic infections. Meanwhile, they are known to be a major obstacle in cancer immunotherapy. On the other hand, MDSC can interfere with allogeneic transplant rejection and may dampen autoreactive T cell activity. Whether MDSC-Exosomes (Exo can cope with the dangerous and potentially therapeutic activities of MDSC is not yet fully explored. After introducing MDSC and Exo, it will be discussed, whether a blockade of MDSC-Exo could foster the efficacy of immunotherapy in cancer and mitigate tumor progression supporting activities of MDSC. It also will be outlined, whether application of native or tailored MDSC-Exo might prohibit autoimmune disease progression. These considerations are based on the steadily increasing knowledge on Exo composition, their capacity to distribute throughout the organism combined with selectivity of targeting, and the ease to tailor Exo and includes open questions that answers will facilitate optimizing protocols for a MDSC-Exo blockade in cancer as well as for strengthening their therapeutic efficacy in autoimmune disease.

High baby birth weight and risk of hormone-associated cancer in mothers: the cancer-cardiovascular disease dichotomy and its possible causes.

Science.gov (United States)

Berstein, Lev M

2013-07-01

The idea of intrauterine or fetal factors being the cause of several prevalent noninfectious diseases in adults has recently gained the status of an axiom. One of the most thoroughly studied predictors is birth weight (BW). Although many published studies point at relations between BW and later adult morbidity or mortality, much less attention is paid to associations between baby BW and maternal morbidity. Available data suggest a sort of dichotomy in these relationships. Thus, cardiovascular risk is higher in mothers of babies with a reduced BW, while cancer risk, mainly of the breast and some other hormone-dependent cancers, is often higher among mothers of babies with a large BW (newborn macrosomia). This review addresses possible causes and endocrine mechanisms of this topic and suggests a 'particular' and 'general' solution for arising controversy. Emphasis is placed on a probable competition between chronic diseases (mainly, between female hormone-related cancer and cardiovascular pathology) within the concept of multiple causes of death. These associations should be remembered while studying the relation between offspring BW and maternal predisposition to hormone-associated cancers and other noncommunicable diseases.

Disease epidemiology during ageing shows a transition from cancer to degenerative chronic disorders as dominant contributors to mortality in the old. Nevertheless, it has remained unclear to what extent molecular signatures of ageing reflect this phenomenon. Here we report on the identification of a conserved transcriptomic signature of ageing based on gene expression data from four vertebrate species across four tissues. We find that ageing-associated transcriptomic changes follow trajectories similar to the transcriptional alterations observed in degenerative ageing diseases but are in opposite direction to the transcriptomic alterations observed in cancer. We confirm the existence of a similar antagonism on the genomic level, where a majority of shared risk alleles which increase the risk of cancer decrease the risk of chronic degenerative disorders and vice versa. These results reveal a fundamental trade-off between cancer and degenerative ageing diseases that sheds light on the pronounced shift in their epidemiology during ageing.

Despite a remarkable increase in the depth of our understanding and management of breast cancer in the past 50 years, the disease is still a major public health problem worldwide and poses significant challenges. The palpability of breast tumors has facilitated diagnosis and documentation since ancient times. The earliest descriptions of breast cancer date back to around 3500 BCE. For centuries to follow, theories by Hippocrates (460 BCE) and Galen (200 CE), attributing the cause of breast cancer to an "excess of black bile" and treatment options including the use of opium and castor oil, prevailed. Surgical resection was introduced in the 18th century. The advent of modern medicine led to the development of novel treatment options that include hormonal, targeted and chemo-therapies. There are still several therapeutic challenges including the treatment of triple negative breast cancer (TNBC), and overcoming drug resistance. The increased incidence and awareness of breast cancer has led to significant changes in diagnosis and treatment in recent decades. But, mankind has come a long way. Herein, I have traced how our understanding of breast cancer has evolved from the early description of the disease around 460 BCE as "black bile-containing crab-like tumors" to the conventional as a heterogeneous disease with high degree of diversity between and within tumors, as well as among breast cancer patients. How is breast cancer treated today and how do risk factors, breast cancer subtype and drug resistance contribute to the therapeutic challenges at the turn of the 21st century? Breast cancer remains a serious public health issue worldwide. However, appreciable growth in our understanding of breast cancer in the past century has led to remarkable progress in the early detection, treatment and prevention of the disease. The clinical focus is shifting more towards tailored therapy as more targets are characterized and novel highly innovative approaches are developed

[Psychological and psychiatric problems in cancer patients: relationship to the localization of the disease].

Cancer may be localized in a variety of areas in the human body. This localization is associated with significant issues concerning not only therapy and prognosis but also psychological and psychiatric problems that the patient may be confronted with. The psychic impact on the patient is determined to a significant degree by the symbolism the affected organ carries. The symbolic significance of a sick body area triggers emotions and sets in motion self-defence mechanisms. In this way, patients deal with the new psychic reality that cancer creates. Therapeutic choices may include interventions, involving mutilation, which cause disfigurement and major consequences in the body image which result in narcissistic injuries. The phenomenology of anxiety and depressive disorders is connected to the affected body area. The appearance of cancer not only in sexual organs but also in other body areas, may disturb sexual function and therefore lead to sexual disorders. Especially, head and neck are connected with vital functions. This area of the body has had a major impact on psychic reality since early life. Complicated psychic functions have developed in relation to organs of the head and neck. Therefore, localization of cancer in this area leads to individual psychological and psychiatric problems, since eating and breathing are harmed, verbal communication becomes difficult and body image alters. Also, increased incidence of alcohol and nicotine abuse in these patients reflects special aspects of psychic structure and personality. Because of severe somatic symptoms and poor prognosis, lung cancer patients feel hopelessness and helplessness. Patients with gynaecological cancer are confronted with a disease that affects organs like breast and internal female sexual organs associated with femininity, attractiveness and fertility. Dietary habits are often a source of guilt for patients who suffer from cancer of the gastrointestinal tract. Additionally, stomas, as colostomy

Role of Cytokine-Induced Glycosylation Changes in Regulating Cell Interactions and Cell Signaling in Inflammatory Diseases and Cancer

Directory of Open Access Journals (Sweden)

2016-11-01

Full Text Available Glycosylation is one of the most important modifications of proteins and lipids, and cell surface glycoconjugates are thought to play important roles in a variety of biological functions including cell-cell and cell-substrate interactions, bacterial adhesion, cell immunogenicity and cell signaling. Alterations of glycosylation are observed in number of diseases such as cancer and chronic inflammation. In that context, pro-inflammatory cytokines have been shown to modulate cell surface glycosylation by regulating the expression of glycosyltransferases involved in the biosynthesis of carbohydrate chains. These changes in cell surface glycosylation are also known to regulate cell signaling and could contribute to disease pathogenesis. This review summarizes our current knowledge of the glycosylation changes induced by pro-inflammatory cytokines, with a particular focus on cancer and cystic fibrosis, and their consequences on cell interactions and signaling.

Second cancers after treatment for Hodgkin's disease: A review

International Nuclear Information System (INIS)

Boivin, J.F.; Hutchison, G.B.

1984-01-01

The authors review several reports of series of patients with Hodgkin's disease among whom second primary cancers have been diagnosed after radiotherapy or chemotherapy or both for Hodgkin's disease. An analysis of these reports suggests that (a) chemotherapy is a strong risk factor for leukemia, and (b) in the absence of chemotherapy, leukemia shows little or no increased incidence over ''spontaneous'' rates. Seven drugs have been identified as being frequently used in treatment of Hodgkin's disease (nitrogen mustard, cyclophosphamide, chlorambucil, procarbazine, vinglastine, vincristine, and prednisone). A large proportion of the patients receiving chemotherapy for Hodgkin's disease are exposed to several drugs and quantitative estimates of the independent leukemogenic effects of these drugs have not yet been obtained. Most of the person-years' experience accrued in the published studies occurred in the first decade after treatment for Hodgkin's disease. Follow-up over longer intervals of time will be necessary before solid tumor risk after therapy for Hodgkin's disease can be evaluated

The paradigm change observed over the last few years in several solid tumors emphasizes the value of locoregional treatment in the presence of metastatic disease, currently ignored in de novo prostate cancer (CaP). We investigated the effect of the primary tumor that is left untreated on prostate cancer-specific morbidity and mortality, time to castration resistance, and overall survival (OS). We performed a bicentric cohort study. The overall population included de novo metastatic CaP managed at the Genito-Urinary Oncology Unit of the Gustave Roussy Institute and the Urology Clinic of the University Hospital of Pointe-à-Pitre, France. Descriptive statistical and outcome analyses were performed in the overall cohort and also separately in the N+M0 and M+subgroups. The overall cohort included 263 patients. Approximately two-thirds of patients (64%) presented with locoregional symptoms at diagnosis, and 78% throughout the disease. Of the symptomatic patients, 59% required a locoregional procedure. Median OS of patients with locoregional symptoms at diagnosis was shorter than in those who were asymptomatic (47 vs. 86 mo, P = 0.0007); this difference was maintained in the N+M0 and M+subgroups. Median OS and time to castration resistance showed a nonsignificant trend in favor of patients undergoing a locoregional treatment at diagnosis. The presence of symptoms due to locoregional disease in de novo metastatic CaP entails significant morbidity and even mortality and requires active management. Randomized prospective trials are needed to evaluate the role of initial definite locoregional treatment in these patients. Copyright © 2015 Elsevier Inc. All rights reserved.

Cigarettes, lung cancer, and coronary heart disease: the effects of inhalation and tar yield.

Science.gov (United States)

Higenbottam, T; Shipley, M J; Rose, G

1982-06-01

Ten-year mortality rates for lung cancer and coronary heart disease have been related to cigarette smoking habits in 17 475 male civil servants aged 40-64 and in sample of 8089 male British residents aged 35-69. Both diseases were more frequent in smokers. Lung cancer rates were higher overall for "non-inhalers", particularly in heavy smokers. Tar yield correlated with the risk of lung cancer in non-inhalers but less so in inhalers. Conversely, coronary deaths were more common among inhalers, and the effect of tar/nicotine yield (such as it was) was confined to inhalers. It appears that there are subtle interactions between the amount smoked, the tar/nicotine yield of the cigarette, and the style of smoking. Thus the effects of a change in cigarette characteristics are hard to predict, and they may be different for respiratory and cardiovascular disease.

Colorectal cancer (CRC) is the third most commonly diagnosed cancer in the US. CRC survivors may have complex healthcare needs requiring care from both specialists and primary care. Our objective was to understand how CRC survivors perceive their survivorship care, especially management of their cardiovascular-related chronic diseases. We identified patients diagnosed with non-metastatic CRC between 10/1/2007 and 12/31/2015 at Veterans Affairs Medical Centers in North Carolina or Virginia. In 2016, we conducted telephone-based, semi-structured interviews to assess survivors' experiences with cancer survivorship and changes in health priorities. Interviews were conducted until thematic saturation was reached. Interviews were audio-recorded, transcribed, and coded. The 25 participants were, on average, 64 years old and approximately 4 years post-CRC diagnosis at the time of interview; most were white (60%), male (92%), and diagnosed with colon cancer (64%) as opposed to rectal cancer. CRC survivors reported: (1) a shift in focus from surviving cancer to reducing cardiovascular disease risk (e.g., by managing weight); (2) challenges with taking medications for CVD-related conditions; (3) new recognition of the importance of engaging with primary care providers. Experiences with cancer shapes how survivors view their health. Management of cardiovascular-related chronic disease is important to veteran CRC survivors. There is a need to deliver cardiovascular disease risk reduction programs tailored for CRC survivors.

Benign breast disease increases the risk of breast cancer. This association has scarcely been evaluated in the context of breast cancer screening programs although it is a prevalent finding in mammography screening. We assessed the association of distinct categories of benign breast disease and subsequent risk of breast cancer, as well as the influence of a family history of breast cancer. A retrospective cohort study was conducted in 545,171 women aged 50-69 years biennially screened for breast cancer in Spain. The median of follow-up was 6.1 years. The age-adjusted rate ratio (RR) of breast cancer for women with benign breast disease, histologically classified into nonproliferative and proliferative disease with and without atypia, compared with women without benign breast disease was estimated by Poisson regression analysis. A stratified analysis by family history of breast cancer was performed in a subsample. All tests were two-sided. The age-adjusted RR of breast cancer after diagnosis of benign breast disease was 2.51 (95 % CI: 2.14-2.93) compared with women without benign breast disease. The risk was higher in women with proliferative disease with atypia (RR = 4.56, 95 % CI: 2.06-10.07) followed by those with proliferative disease without atypia (RR = 3.58; 95 % CI = 2.61-4.91). Women with nonproliferative disease and without a family history of breast cancer remained also at increased risk of cancer (OR = 2.23, 95 % CI: 1.86-2.68). An increased risk of breast cancer was observed among screening participants with proliferative or nonproliferative benign breast disease, regardless of a family history of breast cancer. This information may be useful to explore risk-based screening strategies.

A Gene Module-Based eQTL Analysis Prioritizing Disease Genes and Pathways in Kidney Cancer

Directory of Open Access Journals (Sweden)

Mary Qu Yang

Full Text Available Clear cell renal cell carcinoma (ccRCC is the most common and most aggressive form of renal cell cancer (RCC. The incidence of RCC has increased steadily in recent years. The pathogenesis of renal cell cancer remains poorly understood. Many of the tumor suppressor genes, oncogenes, and dysregulated pathways in ccRCC need to be revealed for improvement of the overall clinical outlook of the disease. Here, we developed a systems biology approach to prioritize the somatic mutated genes that lead to dysregulation of pathways in ccRCC. The method integrated multi-layer information to infer causative mutations and disease genes. First, we identified differential gene modules in ccRCC by coupling transcriptome and protein-protein interactions. Each of these modules consisted of interacting genes that were involved in similar biological processes and their combined expression alterations were significantly associated with disease type. Then, subsequent gene module-based eQTL analysis revealed somatic mutated genes that had driven the expression alterations of differential gene modules. Our study yielded a list of candidate disease genes, including several known ccRCC causative genes such as BAP1 and PBRM1, as well as novel genes such as NOD2, RRM1, CSRNP1, SLC4A2, TTLL1 and CNTN1. The differential gene modules and their driver genes revealed by our study provided a new perspective for understanding the molecular mechanisms underlying the disease. Moreover, we validated the results in independent ccRCC patient datasets. Our study provided a new method for prioritizing disease genes and pathways.

Vitamin D is associated with many health conditions, but optimal blood concentrations are still uncertain. We examined the prospective relation between serum 25-hydroxyvitamin D [25(OH)D] concentrations [which comprised 25(OH)D3 and 25(OH)D2] and subsequent mortality by the cause and incident diseases in a prospective population study. Serum vitamin D concentrations were measured in 14,641 men and women aged 42-82 y in 1997-2000 who were living in Norfolk, United Kingdom, and were followed up to 2012. Participants were categorized into 5 groups according to baseline serum concentrations of total 25(OH)D increasing vitamin D category were 1, 0.84 (0.74, 0.94), 0.72 (0.63, 0.81), 0.71 (0.62, 0.82), and 0.66 (0.55, 0.79) (P-trend disease, diabetes, or cancer, HRs for a 20-nmol/L increase in 25(OH)D were 0.92 (0.88, 0.96) (P disease, 0.89 (0.85, 0.93) (P respiratory disease, 0.89 (0.81, 0.98) (P = 0.012) (563 events) for fractures, and 1.02 (0.99, 1.06) (P = 0.21) (3121 events) for incident total cancers. Plasma 25(OH)D concentrations predict subsequent lower 13-y total mortality and incident cardiovascular disease, respiratory disease, and fractures but not total incident cancers. For mortality, lowest risks were in subjects with concentrations >90 nmol/L, and there was no evidence of increased mortality at high concentrations, suggesting that a moderate increase in population mean concentrations may have potential health benefit, but 120 nmol/L.

Tai Ji Quan for the aging cancer survivor: Mitigating the accelerated development of disability, falls, and cardiovascular disease from cancer treatment

Directory of Open Access Journals (Sweden)

Kerri M. Winters-Stone

2014-03-01

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.

The aim of the present study was to evaluate the possible differences between total laparoscopy and laparotomy regarding their impact on postoperative quality of life and sexuality in disease-free cervical cancer survivors who received radical hysterectomy (RH) and/or lymphadenectomy alone and were followed for >1 year.We reviewed all patients with cervical cancer who had received surgical treatment in our hospital between January 2001 and March 2014. Consecutive sexually active survivors who received RH and/or lymphadenectomy for early stage cervical cancer were enrolled and divided into 2 groups based on surgical approach. Survivors were interviewed and completed validated questionnaires, including the European Organization for Research Treatment of Cancer Quality-of-Life Core Questionnaire including 30 items, the Cervical Cancer-Specific Module of European Organization for Research Treatment of Cancer Quality-of-Life Questionnaire including 24 items (EORTC QLQ-CX24), and the Female Sexual Function Index (FSFI).In total, 273 patients with histologically confirmed cervical cancer were retrospectively reviewed. However, only 64 patients had received RH and/or lymphadenectomy alone; 58 survivors meeting the inclusion criteria were enrolled, including 42 total laparoscopy cases and 16 laparotomy cases, with an average follow-up of 46.1 and 51.2 months, respectively. The survivors in the 2 groups obtained good and similar scores on all items of the European Organization for Research Treatment of Cancer Quality-of-Life Core Questionnaire including 30 items and Cervical Cancer-Specific Module of European Organization for Research Treatment of Cancer Quality-of-Life Questionnaire including 24 items, without significant differences after controlling for covariate background characteristics. To the date of submission, 21.4% (9/42) of cases in the total laparoscopy group and 31.2% (5/16) of cases in the laparotomy group had not resumed sexual behavior after RH. Additionally

UV-induced skin cancer is not yet included in the German ordinance on occupational diseases and can only be notified and recognized acknowledged as "virtually-certain" occupational disease. The objective of the study was to analyze notified and acknowledged cases of occupational skin cancer due to UV-irradiation in Germany between 2005 and 2011. All notified cases of occupational skin cancer due to UV-irradiation have been analyzed which have been registered by the German Statutory accident insurance as of May 2012 were analyzed. The data analyze was descriptive stratified annually for presenting time trends.Data analysis was descriptive, stratified by year to defect time trends. Notified cases have increased annually with a total of 548 registered cases of occupational skin cancer induced by UV-irradiation between 2005 and 2011, and 74 recognized acknowledged cases. In 56 cases the procedure was not yet finished. Squamous cell carcinoma (SCC) and in-situ squamous cell carcinoma (actinic keratosis, Bowen's disease) were most frequent and have been the most frequentlyobserved in 333 notified cases. and between 15.6 % and 24.9 % have been recognizedof cases with SCC and actinic keratosis were recognized, respectively. 184 patients with basal cell carcinoma were notified but only 6.5 % recognized acknowledged and only 3 cases with exclusive basal cell carcinoma. Out of 50 notified patients with Mmelanoma only one was recognizedacknowledged. The results are in good agreement with the proposal of the German Minister of labor to establish UV-induced skin cancer as a new occupational disease. © 2014 Deutsche Dermatologische Gesellschaft (DDG).

2013-09-01

Membrane microparticles (MPs) are plasma membrane-derived vesicles shed by various types of activated or apoptotic cells including platelets, monocytes, endothelial cells, red blood cells, and granulocytes. MPs are being increasingly recognized as important regulators of cell-to-cell interactions. Recent evidences suggest they may play important functions not only in homeostasis but also in the pathogenesis of a number of diseases such as vascular diseases, cancer, infectious diseases and diabetes mellitus. Accordingly, inhibiting the production of MPs may serve as a novel therapeutic strategy for these diseases. Here we review recent advances on the mechanism underlying the generation of MPs and the role of MPs in vascular diseases, cancer, diabetes, inflammation, and pathogen infection.

High levels of microRNA-21 in the stroma of colorectal cancers predict short disease-free survival in stage II colon cancer patients

Natural products as potential cancer therapy enhancers: A preclinical update

Directory of Open Access Journals (Sweden)

Abed Agbarya

2014-09-01

Full Text Available Cancer is a multifactorial disease that arises as a consequence of alterations in many physiological processes. Recently, hallmarks of cancer were suggested that include sustaining proliferative signaling, evading growth suppressors, resisting cell death, enabling replicative immortality, inducing angiogenesis, and activating invasion and metastasis, along with two emerging hallmarks including reprogramming energy metabolism and escaping immune destruction. Treating multifactorial diseases, such as cancer with agents targeting a single target, might provide partial treatment and, in many cases, disappointing cure rates. Epidemiological studies have consistently shown that the regular consumption of fruits and vegetables is strongly associated with a reduced risk of developing chronic diseases, such as cardiovascular diseases and cancer. Since ancient times, plants, herbs, and other natural products have been used as healing agents. Moreover, the majority of the medicinal substances available today have their origin in natural compounds. Traditionally, pharmaceuticals are used to cure diseases, and nutrition and herbs are used to prevent disease and to provide an optimal balance of macro- and micro-nutrients needed for good health. We explored the combination of natural products, dietary nutrition, and cancer chemotherapeutics for improving the efficacy of cancer chemotherapeutics and negating side effects.

The relationship between lifestyle factors, past medical conditions, daily meal frequency, diet and the risk of 'familial' colorectal cancer has been analysed using data from a case-control study conducted in northern Italy. A total of 1584 colorectal cancer patients and 2879 control subjects were admitted to a network of hospitals in the Greater Milan area and the Pordenone province. The subjects included for analysis were the 112 cases and the 108 control subjects who reported a family history of colorectal cancer in first-degree relatives. Colorectal cancer cases and control subjects with family history were similarly distributed according to sex, age, marital status, years of schooling and social class. Familial colorectal cancer was associated with meal frequency, medical history of diabetes (relative risk, RR = 4.6) and cholelithiasis (RR = 5.2). Significant positive trends of increasing risk with more frequent consumption were observed for pasta (RR = 2.5, for the highest vs the lowest intake tertile), pastries (RR = 2.4), red meat (RR = 2.9), canned meat (RR = 1.9), cheese (RR = 3.5) and butter (RR = 1.9). Significant inverse associations and trends in risk were observed for consumption of poultry (RR = 0.4), tomatoes (RR = 0.2), peppers (RR = 0.3) and lettuce (RR = 0.3). Significant inverse trends in risk with increasing consumption for beta-carotene and ascorbic acid were observed (RR = 0.5 and 0.4 respectively, highest vs lowest intake tertile). These results suggest that risk factors for subjects with a family history of colorectal cancer in first-degree relatives are not appreciably different from recognized risk factors of the disease in the general population.

To date, there is no unified approach to evaluating and treating patients with suspected prostate cancer taking into account their age and comorbidities. That was the rationale for conducting this study. To assess the clinical course of prostate cancer in men of all ages with comorbidities. The study included 408 patients aged 50 to 92 years (mean age 74.3 years) with histologically verified prostate cancer. 30 (7.4%) patients had stage T1 disease, 273 (66.9%) - T2, 91 (22.3%) - T3 and 14 (3.4%) - T4. The maximum follow-up was 22 years, the minimum one - 6 months (on average 15.4 years). During the follow-up 159 patients died (39%), 51 of them (32%) of prostate cancer, 108 (68%) - from other diseases. Among the latter the causes of death were cancer (20.4%), cardiovascular and bronchopulmonary diseases (79.6%). Cancer-specific survival rate was 41.4 +/-12,4%, the survival rate for other diseases 23.4 +/-10,6% (pcancer, especially of old age, including the option for active surveillance of patients with clinically insignificant prostate cancer.

Periodontal diseases including tooth loss might increase systemic inflammation, lead to immune dysregulation and alter gut microbiota, thereby possibly influencing colorectal carcinogenesis. Few epidemiological studies have examined the association between periodontal diseases and colorectal cancer (CRC) risk. We collected information on the periodontal disease (defined as history of periodontal bone loss) and number of natural teeth in the Nurses' Health Study. A total of 77,443 women were followed since 1992. We used Cox proportional hazard models to calculate multivariable hazard ratios (HRs) and 95% confidence intervals (95% CIs) after adjustment for smoking and other known risk factors for CRC. We documented 1,165 incident CRC through 2010. Compared to women with 25-32 teeth, the multivariable HR (95% CI) for CRC for women with periodontal disease, HRs for CRC were 0.91 (95% CI 0.74-1.12) for periodontal disease, and 1.22 (95% CI 0.91-1.63) when limited to moderate to severe periodontal disease. The results were not modified by smoking status, body mass index or alcohol consumption. Women with fewer teeth, possibly moderate or severe periodontal disease, might be at a modest increased risk of developing CRC, suggesting a potential role of oral health in colorectal carcinogenesis. © 2016 UICC.

To determine dysplasia and cancer in the 1991-2004 European Collaborative Inflammatory Bowel Disease (EC-IBD) Study Group cohort. A patient questionnaire and a physician per patient form were completed for each of the 1,141 inflammatory bowel disease patients (776 ulcerative colitis/365 Crohn's disease) from 9 centers (7 countries) derived from the EC-IBD cohort. Rates of detection of intestinal cancer and dysplasia as well as extra-intestinal neoplasms were computed. Patient follow-up time was 10.3 +/- 0.8 (range 9.4-11) years. The mean age of the whole group of IBD patients was 37.8 +/- 11.3 (range 16-76) years. Thirty-eight patients (3.3%; 26 with ulcerative colitis/12 with Crohn's disease, 21 males/17 females, aged 61.3 +/- 13.4, range 33-77 years), were diagnosed with 42 cancers. Cancers occurred 5.4 +/- 3.3 (range 0-11) years after inflammatory bowel disease diagnosis. Colorectal cancer was diagnosed in 8 (1 Crohn's disease and 7 ulcerative colitis patients--0.3 and 0.9% of the Crohn's disease and ulcerative colitis cohort, respectively) of 38 patients and 30 cancers were extra-intestinal. Four of 38 patients (10.5%) were diagnosed as having 2 cancers and they were younger compared to patients with one cancer (p = 0.0008). There was a trend for a higher prevalence of intestinal cancer in the northern centers (0.9%) compared to southern centers (0.3%, p = NS). Southern centers had more cases of extra-intestinal cancer compared to northern centers (2 vs. 3.8%, p = 0.08). Ten patients (0.9%; 8 with ulcerative colitis/2 with Crohn's disease, 8 males, aged 62.3 +/- 14.1 years) had colorectal dysplasia. In the first decade of the EC-IBD Study Group cohort follow-up study, the prevalence of cancer was as expected with most patients having a single neoplasm and an extra-intestinal neoplasm. In northern centers there was a trend for more intestinal cancers, while in southern centers there was a trend for more extra-intestinal cancers compared to northern centers. 2007

STRESS AS PREDISPOSING FACTOR OF SOME CHRONIC DISEASES INCLUDING PERIODONTAL DISEASE

Directory of Open Access Journals (Sweden)

Dewi-Nurul M Dewi-Nurul

2006-04-01

Full Text Available Stress is hypothesized as a common pathway for several related chronic diseases of man. Psychosocial stress as modified by perceptions and coping by patients can lead to physical processes. Psychoneuroimmunologic (PNI studies have suggested that psychosocial stress can alter immune function and increase vulnerability to illnesses. The patients also have high sensitivity to periodontal disease (PD. This article describes the association of stress as a physiological response to diseases such as PD, rheumatoid arthritis (RA, and inflammatory bowel disease. The psychosocial stress can lead to physiological processes through 1 the hypothalamic-pituitary-adrenal (HPA axis leading to glucocortico-steroid secretion; 2 the autonomic nervous system, resulting in the release of catecholamine; or 3 the hypothalamic-pituitary-gonadal axis, resulting in the release of sex hormones. These processes may affect chronic diseases. It can be concluded that psychosocial stress in periodontal disease patients must be considered and social support must be provided in order to achieve an optimum periodontal therapy result.

Cervical cancer is the second most common cancer among women worldwide, with developing countries accounting for >80% of the disease burden. Although in the West, active screening has been instrumental in reducing the incidence of cervical cancer, disease management is hampered due to lack of biomarkers for disease progression and defined therapeutic targets. Here we carried out gene expression profiling of 29 cervical cancer tissues from Indian women, spanning International Federation of Gynaecology and Obstetrics (FIGO) stages of the disease from early lesion (IA and IIA) to progressive stages (IIB and IIIA–B), and identified distinct gene expression signatures. Overall, metabolic pathways, pathways in cancer and signaling pathways were found to be significantly upregulated, while focal adhesion, cytokine–cytokine receptor interaction and WNT signaling were downregulated. Additionally, we identified candidate biomarkers of disease progression such as SPP1, proliferating cell nuclear antigen (PCNA), STK17A, and DUSP1 among others that were validated by quantitative real-time polymerase chain reaction (qRT-PCR) in the samples used for microarray studies as well in an independent set of 34 additional samples. Integrative analysis of our results with other cervical cancer profiling studies could facilitate the development of multiplex diagnostic markers of cervical cancer progression

Different site specificity of second primary cancer following treatment for early stage squamous cell carcinoma of the head and neck was found in the analysis of post-treatment long-term follow up cases. The highest risk of second primary cancer was observed in the oro-hypo-pharynx cancer groups, and the lowest risks were observed in the epi-pharynx cancer and maxillary sinus cancer groups. Squamous cell carcinoma in the irradiated head and neck region with long latency periods could be included in the radiation induced cancer from comparison with post-irradiation cases for malignant lymphoma, benign diseases as well as breast cancers.

Full Text Available Time trajectories of medical costs-associated with onset of twelve aging-related cancer and chronic noncancer diseases were analyzed using the National Long-Term Care Survey data linked to Medicare Service Use files. A special procedure for selecting individuals with onset of each disease was developed and used for identification of the date at disease onset. Medical cost trajectories were found to be represented by a parametric model with four easily interpretable parameters reflecting: (i prediagnosis cost (associated with initial comorbidity, (ii cost of the disease onset, (iii population recovery representing reduction of the medical expenses associated with a disease since diagnosis was made, and (iv acquired comorbidity representing the difference between post- and pre diagnosis medical cost levels. These parameters were evaluated for the entire US population as well as for the subpopulation conditional on age, disability and comorbidity states, and survival (2.5 years after the date of onset. The developed approach results in a family of new forecasting models with covariates.

[Landscape of Lung Cancer with Oligometastasis].

Science.gov (United States)

Goto, Yasushi; Sato, Jun

2017-10-01

Lung cancer with a few to several metastases is so-called oligometastatic disease. Patient with recurrence only to limited site is also known as oligo-recurrence, and may be included as oligometastatic disease. From biological aspect, any existence of metastases is a sign of systemic disease. Due to the reports of long survival with only local treatment and without systemic disease in oligometastatic lung cancer, word of oligometastasis is used with fascinating expectation of cure to advanced lung cancer. Most of the previous reports are retrospective and no comprehensive data exists for selecting patient for local treatment to oligometastasis. Recent positive result of randomize phase II study is followed up with phase III study. Progress in treatment of advanced non-small cell lung cancer with targeted therapy to oncogenic-driver(EGFR, ALK, ROS1 and others) and immune-checkpoint inhibitor(PD-1 pathway inhibitors)makes it difficult to define the appropriate indication of local treatment to oligometastatic lung cancer.

Over the past 25 years there have been dramatic improvements in our understanding of the epidemiology, biology, natural history, and treatment of Hodgkins disease. Hodgkin's disease is one of the few cancers where both chemotherapy and radiation therapy have provided dramatic improvements in cure of this once uniformly fatal disease. Part 1 of the refresher course on Hodgkin's disease will include a review of: 1) New Findings in epidemiology, immunohistochemistry and molecular biology of the Reed-Sternberg cell including association with Epstein-Barr virus; 2) Review of pathology including discussions of NS 1 vs NS2, and nodular LP subclassifications; 3) Recommendations for staging including the role of staging laparotomy in Hodgkin's disease; 4) Standard techniques for commonly used radiation therapy fields for Hodgkin's disease and 5) Treatment of early stage Hodgkin's disease including an overview on recent and current clinical trials

The purpose of this study was to evaluate the risks of second cancers and cardiovascular diseases associated with an optimized volumetric modulated arc therapy (VMAT) planning solution in a selected cohort of stage I/II Hodgkin lymphoma (HL) patients treated with either involved-node or involved-site radiation therapy in comparison with 3-dimensional conformal radiation therapy (3D-CRT). Thirty-eight patients (13 males and 25 females) were included. Disease extent was mediastinum alone (n=8, 21.1%); mediastinum plus unilateral neck (n=19, 50%); mediastinum plus bilateral neck (n=11, 29.9%). Prescription dose was 30 Gy in 2-Gy fractions. Only 5 patients had mediastinal bulky disease at diagnosis (13.1%). Anteroposterior 3D-CRT was compared with a multiarc optimized VMAT solution. Lung, breast, and thyroid cancer risks were estimated by calculating a lifetime attributable risk (LAR), with a LAR ratio (LAR(VMAT)-to-LAR(3D-CRT)) as a comparative measure. Cardiac toxicity risks were estimated by calculating absolute excess risk (AER). The LAR ratio favored 3D-CRT for lung cancer induction risk in mediastinal alone (P=.004) and mediastinal plus unilateral neck (P=.02) presentations. LAR ratio for breast cancer was lower for VMAT in mediastinal plus bilateral neck presentations (P=.02), without differences for other sites. For thyroid cancer, no significant differences were observed, regardless of anatomical presentation. A significantly lower AER of cardiac (P=.038) and valvular diseases (Pdisease extent. In a cohort of patients with favorable characteristics in terms of disease extent at diagnosis (large prevalence of nonbulky presentations without axillary involvement), optimized VMAT reduced heart disease risk with comparable risks of thyroid and breast cancer, with an increase in lung cancer induction probability. The results are however strongly influenced by the different anatomical presentations, supporting an individualized approach. Copyright © 2015 Elsevier

Patients with inflammatory bowel diseases, such as Crohn's disease (CD) and ulcerative colitis (UC), are at increased risk for small bowel or colorectal cancers (colitis-associated cancers [CACs]). We compared the spectrum of genomic alterations in CACs with those of sporadic colorectal cancers (CRCs) and investigated differences between CACs from patients with CD vs UC. We studied tumor tissues from patients with CACs treated at Memorial Sloan Kettering Cancer Center or Weill Cornell Medical College from 2003 through 2015. We performed hybrid capture-based next-generation sequencing analysis of >300 cancer-related genes to comprehensively characterize genomic alterations. We performed genomic analyses of 47 CACs (from 29 patients with UC and 18 with CD; 43 primary tumors and 4 metastases). Primary tumors developed in the ileum (n = 2), right colon (n = 18), left colon (n = 6), and rectosigmoid or rectum (n = 21). We found genomic alterations in TP53, IDH1, and MYC to be significantly more frequent, and mutations in APC to be significantly less frequent, than those reported in sporadic CRCs by The Cancer Genome Atlas or Foundation Medicine. We identified genomic alterations that might be targeted by a therapeutic agent in 17 of 47 (36%) CACs. These included the mutation encoding IDH1 R132; amplification of FGFR1, FGFR2, and ERBB2; and mutations encoding BRAF V600E and an EML4-ALK fusion protein. Alterations in IDH1 and APC were significantly more common in CACs from patients with CD than UC. In an analysis of CACs from 47 patients, we found significant differences in the spectrum of genomic alterations in CACs compared with sporadic CRCs. We observed a high frequency of IDH1 R132 mutations in patients with CD but not UC, as well as a high frequency of MYC amplification in CACs. Many genetic alterations observed in CACs could serve as therapeutic targets. Copyright © 2016 AGA Institute. Published by Elsevier Inc. All rights reserved.

2010-03-01

Full Text Available Abstract Background Colorectal cancer (CRC is often diagnosed at a late stage with concomitant poor prognosis. The hypersensitive analytical technique of proteomics can detect molecular changes before the tumor is palpable. The surface-enhanced laser desorption/ionization-time of flight-mass spectra (SELDI-TOF-MS is a newly-developed technique of evaluating protein separation in recent years. The protein chips have established the expression of tumor protein in the serum specimens and become the newly discovered markers for tumor diagnosis. The objective of this study was to find new markers of the diagnosis among groups of CRC, colorectal benign diseases (CBD and healthy controls. The assay of SELDI-TOF-MS with analytical technique of protein-chip bioinformatics was used to detect the expression of protein mass peaks in the sera of patients or controls. One hundred serum samples, including 52 cases of colorectal cancer, 27 cases of colorectal benign disease, and 21 cases of healthy controls, were examined by SELDI-TOF-MS with WCX2 protein-chips. Results The diagnostic models (I, II and III were setup by analyzed the data and sieved markers using Ciphergen - Protein-Chip-Software 5.1. These models were combined with 3 protein mass peaks to discriminate CRC, CBD, and healthy controls. The accuracy, the sensitivity and the particularity of cross verification of these models are all highly over 80%. Conclusions The SELDI-TOF-MS is a useful tool to help diagnose colorectal cancer, especially during the early stage. However, identification of the significantly differentiated proteins needs further study.

Full Text Available Abstract Background Recent evidence suggests that neutrophil gelatinase-associated lipocalin (NGAL expression is induced in many types of human cancer, while detection of its complex with matrix metalloproteinase-9 (MMP-9 is correlated with cancer disease status. We aim to evaluate the serum expression of MMP-9, NGAL and their complex (MMP-9/NGAL during the diagnostic work-up of women with breast abnormalities and investigate their correlation with disease severity. Methods The study included 113 women with non-palpable breast lesions undergoing vacuum-assisted breast biopsy for histological diagnosis, and 30 healthy women, which served as controls. Expression levels of MMP-9, NGAL and their complex MMP-9/NGAL were determined in peripheral blood samples with immunoenzymatic assays. Results Women with invasive ductal carcinoma exhibited significantly increased levels of MMP-9, NGAL and MMP-9/NGAL compared to healthy controls (MMP-9: p Conclusion These findings suggest that the serum measurement of MMP-9 and NGAL may be useful in non-invasively monitoring breast cancer progression, while supporting their potential role as early biomarkers of breast disease status.

Cancer cells secrete factors that influence adjacent cell behavior and can lead to enhanced proliferation and metastasis. To better understand the role of these factors in oncogenesis and disease progression, estrogen and progesterone receptor positive MCF-7 cells, triple negative breast cancer MDA-MB-231, DT22, and DT28 cells, and MCF-10A non-transformed mammary epithelial cells were grown in 3D cultures. A special emphasis was placed on triple negative breast cancer since these tumors are highly aggressive and no targeted treatments are currently available. The breast cancer cells secreted factors of variable potency that stimulated proliferation of the relatively quiescent MCF-10A cells. The conditioned medium from each cell line was subjected to mass spectrometry analysis and a variety of secreted proteins were identified including glycolytic enzymes, proteases, protease inhibitors, extracellular matrix proteins, and insulin-like growth factor binding proteins. An investigation of the secretome from each cell line yielded clues about strategies used for breast cancer proliferation and metastasis. Some of the proteins we identified may be useful in the development of a serum-based test for breast cancer detection, diagnosis, prognosis, and monitoring.

Predictive biomarkers can play a key role in individualized disease monitoring. Unfortunately, the use of biomarkers in clinical settings has thus far been limited. We have previously shown that mechanism-based pharmacokinetic/pharmacodynamic modeling enables integration of nonvalidated biomarker data to provide predictive model-based biomarkers for response classification. The biomarker model we developed incorporates an underlying latent variable (disease) representing (unobserved) tumor size dynamics, which is assumed to drive biomarker production and to be influenced by exposure to treatment. Here, we show that by integrating CT scan data, the population model can be expanded to include patient outcome. Moreover, we show that in conjunction with routine medical monitoring data, the population model can support accurate individual predictions of outcome. Our combined model predicts that a change in disease of 29.2% (relative standard error 20%) between two consecutive CT scans (i.e., 6-8 weeks) gives a probability of disease progression of 50%. We apply this framework to an external dataset containing biomarker data from 22 small cell lung cancer patients (four patients progressing during follow-up). Using only data up until the end of treatment (a total of 137 lactate dehydrogenase and 77 neuron-specific enolase observations), the statistical framework prospectively identified 75% of the individuals as having a predictable outcome in follow-up visits. This included two of the four patients who eventually progressed. In all identified individuals, the model-predicted outcomes matched the observed outcomes. This framework allows at risk patients to be identified early and therapeutic intervention/monitoring to be adjusted individually, which may improve overall patient survival. ©2015 American Association for Cancer Research.

Cervical cancer is the third most common cancer worldwide. Accurate information about cervical cancer to general public can lower the burden of the disease including its mortality. We aimed to look at the quality of information available in YouTube for cervical cancer. We searched YouTube (http://www.youtube.com) for videos using the keyword Cervical cancer on November 12, 2015. Videos were then analyzed for their source and content of information. We studied 172 videos using the keyword Cervical cancer on November 12, 2015. We found that there were videos describing the personal stories, risk factors, and the importance of screening. However, videos discussing all the aspects of cancers were lacking. Likewise, videos from the reputed organization were also lacking. Although there were numerous videos available in cervical cancer, videos from reputed organizations including Center for Disease Control and Prevention, American Cancer Society, and World Health Organization were lacking. We strongly believe that quality videos from such organizations via YouTube can help lower the burden of disease.

We show that combined multimodal nonlinear optical (NLO) microscopies, including two-photon excitation fluorescence, second-harmonic generation (SHG), third harmonic generation, and fluorescence lifetime imaging microscopy (FLIM) can be used to detect morphological and metabolic changes associated with stroma and epithelial transformation during the progression of cancer and osteogenesis imperfecta (OI) disease. NLO microscopes provide complementary information about tissue microstructure, showing distinctive patterns for different types of human breast cancer, mucinous ovarian tumors, and skin dermis of patients with OI. Using a set of scoring methods (anisotropy, correlation, uniformity, entropy, and lifetime components), we found significant differences in the content, distribution and organization of collagen fibrils in the stroma of breast and ovary as well as in the dermis of skin. We suggest that our results provide a framework for using NLO techniques as a clinical diagnostic tool for human cancer and OI. We further suggest that the SHG and FLIM metrics described could be applied to other connective or epithelial tissue disorders that are characterized by abnormal cells proliferation and collagen assembly.

Purpose: To study incidence of radiation-related heart disease in a large population of breast cancer patients followed for up to 30 years. Material and methods: 72,134 women diagnosed with breast cancer in Denmark or Sweden during 1976-2006 and followed prospectively. Radiation-related risk was studied by comparing women with left-sided and right-sided tumours. Results: 34,825 women (48%) received radiotherapy. Among unirradiated women tumour laterality had little relevance to heart disease. Among irradiated women mean dose to the whole heart was 6.3 Gy for left-sided tumours and 2.7 Gy for right-sided tumours. Mortality was similar in irradiated women with left-sided and right-sided tumours, but incidence ratios, left-sided versus right-sided, were raised: acute myocardial infarction 1.22 (95% CI 1.06-1.42), angina 1.25 (1.05-1.49), pericarditis 1.61 (1.06-2.43), valvular heart disease 1.54 (1.11-2.13). Incidence ratios for all heart disease were as high for women irradiated since 1990 (1.09 [1.00-1.19]) as for women irradiated during 1976-1989 (1.08 [0.99-1.17]), and were higher for women diagnosed with ischaemic heart disease prior to breast cancer than for other women (1.58 [1.19-2.10] versus 1.08 [1.01-1.15], p for difference = 0.01). Conclusions: Breast cancer radiotherapy has, at least until recently, increased the risk of developing ischaemic heart disease, pericarditis and valvular disease. Women with ischaemic heart disease before breast cancer diagnosis may have incurred higher risks than others.

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.

The postoperative outcome after elective sigmoidectomy for diverticulitis has not been compared to that for cancer. The study aimed to evaluate the differences in the postoperative outcome after sigmoidectomy for diverticular disease and cancer. The National Inpatient Sample Database was used to identify patients who underwent elective sigmoid resection for diverticular disease or cancer between 2004 and 2011. After excluding patients with metastatic cancer and preoperative weight loss, sigmoid cancer and diverticulitis patients were matched using propensity score, controlling for age, gender, race, type of operation (open vs laparoscopic) and comorbidities. The end-points of interest were infective complications, reoperation, anastomotic leakage, rebleeding, length of hospital stay and in-hospital mortality. After propensity score matching (diverticulitis 11 192 patients, sigmoid cancer 11 192 patients), the mean age was 65 ± 12.5 years, 53.8% were male and 61.5% were Caucasian. Only 18.0% of the operations were done by laparoscopy. The overall complication rate was 17.7% and the in-hospital mortality rate was 0.9%. The diverticulitis group had a higher rate of surgical site infection (3.2% vs 2.6%, P = 0.004), intra-abdominal abscess formation (1.2% vs 0.4%, P diverticular disease has a higher risk of infective complications, elective sigmoidectomy for cancer has a higher risk of anastomotic leakage.

Full Text Available Cancer is a multifaceted condition, in which a senescent cell begins dividing in an irregular manner due to various factors such as DNA damage, growth factors and inflammation. Inflammation is not typically discussed as carcinogenic; however, a significant percentage of cancers arise from chronic microbial infections and damage brought on by chronic inflammation. A hallmark cancer-inducing microbe is Helicobacter pylori and its causation of peptic ulcers and potentially gastric cancer. This review discusses the recent developments in understanding microbes in health and disease and their potential role in the progression of cancer. To date, microbes can be linked to almost every cancer, including colon, pancreatic, gastric, and even prostate. We discuss the known mechanisms by which these microbes can induce cancer growth and development and how inflammatory cells may contribute to cancer progression. We also discuss new treatments that target the chronic inflammatory conditions and their associated cancers, and the impact microbes have on treatment success. Finally, we examine common dietary misconceptions in relation to microbes and cancer and how to avoid getting caught up in the misinterpretation and over inflation of the results.

cohorts and the Long Life Family Study (LLFS) to investigate gender-specific effects of the ApoE4 allele on human survival in a wide range of ages from midlife to extreme old ages, and the sensitivity of these effects to cardiovascular disease (CVD), cancer, and neurodegenerative disorders (ND.......6 × 10(-6)) in the FHS cohorts. Major human diseases including CVD, ND, and cancer, whose risks can be sensitive to the e4 allele, do not mediate the association of this allele with lifespan in large FHS samples. Non-skin cancer non-additively increases mortality of the FHS women with moderate lifespans...... by 150% (p = 5.3 × 10(-8)) compared to the non-carriers. This risk explains the 4.2 year shorter life expectancy of the e4 carriers compared to the non-carriers in this sample. The analyses suggest the existence of age- and gender-sensitive systemic mechanisms linking the e4 allele to lifespan which can...

Abstract Objective. The aim of this study was to analyse the prevalence of osteoporosis and risk factors of osteoporotic fractures before androgen deprivation in Danish men. Treatment and prognosis of prostate cancer necessitate management of long-term consequences of androgen deprivation therapy...... (ADT), including accelerated bone loss resulting in osteoporosis. Osteoporotic fractures are associated with excess morbidity and mortality. Material and methods. Patients with prostate cancer awaiting initiation of ADT were consecutively included. Half of the patients had localized disease and were...... level was 30.5 g/l (1-5714 g/l). The average Gleason score was 7.8 (range 5-10, SD 1.1). Fifty patients had localized prostate cancer and the other 55 patients had disseminated disease. The prevalence of osteoporosis was 10% and the prevalence of osteopenia was 58% before ADT. There was no significant...

Expression of the Long Non-Coding RNA HOTAIR Correlates with Disease Progression in Bladder Cancer and Is Contained in Bladder Cancer Patient Urinary Exosomes.

Directory of Open Access Journals (Sweden)

Claudia Berrondo

Full Text Available Exosomes are 30-150nM membrane-bound secreted vesicles that are readily isolated from biological fluids such as urine (UEs. Exosomes contain proteins, micro RNA (miRNA, messenger RNA (mRNA, and long non-coding RNA (lncRNA from their cells of origin. Although miRNA, protein and lncRNA have been isolated from serum as potential biomarkers for benign and malignant disease, it is unknown if lncRNAs in UEs from urothelial bladder cancer (UBC patients can serve as biomarkers. lncRNAs are > 200 nucleotide long transcripts that do not encode protein and play critical roles in tumor biology. As the number of recognized tumor-associated lncRNAs continues to increase, there is a parallel need to include lncRNAs into biomarker discovery and therapeutic target algorithms. The lncRNA HOX transcript antisense RNA (HOTAIR has been shown to facilitate tumor initiation and progression and is associated with poor prognosis in several cancers. The importance of HOTAIR in cancer biology has sparked interest in using HOTAIR as a biomarker and potential therapeutic target. Here we show HOTAIR and several tumor-associated lncRNAs are enriched in UEs from UBC patients with high-grade muscle-invasive disease (HGMI pT2-pT4. Knockdown of HOTAIR in UBC cell lines reduces in vitro migration and invasion. Importantly, loss of HOTAIR expression in UBC cell lines alters expression of epithelial-to-mesenchyme transition (EMT genes including SNAI1, TWIST1, ZEB1, ZO1, MMP1 LAMB3, and LAMC2. Finally, we used RNA-sequencing to identify four additional lncRNAs enriched in UBC patient UEs. These data, suggest that UE-derived lncRNA may potentially serve as biomarkers and therapeutic targets.
