[PMID: 37559501 PMCID: PMC10557857 DOI: 10.1002/cam4.6451] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/23/2023] [Revised: 07/20/2023] [Accepted: 08/03/2023] [Indexed: 08/11/2023] Open
Abstract
BACKGROUND Cancer mortality rates overall in the U.S. have decreased significantly; however, the rate of decline has not been uniform across sociodemographic groups. We aimed to compare trends in cancer mortality rates from 1999 to 2020 between rural and urban individuals and to examine whether any rural-urban differences are uniform across racial and ethnic groups. METHODS We used U.S.-wide data from the National Center for Health Statistics, for all cancer deaths among individuals aged 25 years or older. We estimated average annual percentage change (AAPC) in age-standardized cancer mortality rates in the U.S. by cancer type, rural-urban status, sex, and race and ethnicity. RESULTS There was a larger reduction in cancer mortality rates among individuals from urban (males: AAPC, -1.96%; 95% CI, -2.03, -1.90; females: AAPC, -1.56%; 95% CI, -1.64, -1.48) than rural (males: AAPC, -1.43%; 95% CI, -1.47, -1.39; females: AAPC, -0.93; 95% CI, -1.03, -0.82) areas. AAPCs for cancer types were uniformly higher among urban areas compared with rural areas. Despite overall decreases, deaths rates for liver and pancreas cancers increased, including in the most recent period among males (2012-2020, APC, 1.34; 95% CI, 0.49, 2.20) and females (2013-2020, APC, 1.52; 95% CI, 0.03, 3.02) in rural areas. CONCLUSIONS Cancer death rates decreased in all racial and ethnic populations; however, the rural-urban differences varied by race/ethnicity. The rate of decline in mortality rates were lower in rural areas and death rates for liver and pancreas cancers increased, particularly for individuals living in rural America.

Abstract
Cardiovascular diseases are the leading causes of death worldwide, closely followed by cancer. To investigate the impact of breast cancer cell lines (SKBR3, MCF-7, and MDA-MB-231) on endothelial cell adhesion, a blended medium containing 30% breast-cancer-conditioned medium was prepared. This medium was then exposed to human umbilical vein endothelial cells (HUVECs) and monocytes (THP-1) for 48 h. Homemade oxidized low-density lipoproteins (oxLDL) were optionally added to the blended medium. Immunofluorescence was performed to assess the expression of E-selectin, connexin-43, and ICAM-1 on HUVECs, as well as LOX-1, CD36, and CD162 on THP-1. Additionally, unoxidized LDL was exposed to the three breast cancer cell lines for 48 h, and the formation of oxLDL was quantified. Our results revealed an upregulation of all six adhesion markers involved in the initiation of atherosclerosis when HUVECs and THP-1 were exposed to the breast-cancer-conditioned medium. Furthermore, this expression was further increased by exposure to oxLDL. We also observed a significant elevation in oxLDL levels when LDL was exposed to breast cancer cells. In conclusion, our findings successfully demonstrate an increased LDL oxidation in the presence of breast cancer cells, accompanied by an augmented expression of receptors involved in atherosclerosis initiation. These findings shed new light on the clinically observed interplay between atherosclerosis and cancer.

Abstract
PURPOSE Due to improved therapy, early diagnosis, and growing incidence rates, the number of long-term breast cancer survivors is increasing. Survivors can still be affected by aftercare, resulting in reduced quality of life (QoL). Thus, in this study, we investigated possible predictors of decreased physical and social functioning in breast cancer survivors. METHODS In a German multicenter prospective study, we enrolled 759 female patients with breast cancer before surgery (t1), and contacted them again 5 years after surgery (t4). Data on QoL were assessed at t4 using the European Organization for Research and Treatment of Cancer QoL Core Questionnaire (EORTC QLQ-C30) and its breast cancer module EORTC QLQ-BR23. Predictors of decreased physical and social functioning were analyzed using logistic regression with odds ratios as effect estimates and 95% confidence intervals. Thresholds for the clinical importance of detrimental effects on QoL were defined according to Giesinger. RESULTS Questionnaires from 759 patients were retrieved at t1. Of these, 456 participated in the study at t4. Poor QoL 5 years after diagnosis was reported by 20%-50% of the participants. Age, mastectomy, chemotherapy, education, employment, cohabitation, psychiatric comorbidities at t1, anxiety, depression, and intensity of physical activity emerged as predictors of decreased physical and social functioning 5 years after diagnosis. CONCLUSION Relief of symptoms and improvement in the QoL should be priorities in aftercare. Detecting patients with a decreased QoL is a rising challenge. Healthcare providers should take special care of patients aged 50-59 years, patients with psychiatric comorbidities and depression, and patients who have undergone mastectomy.

Abstract
Cancer and coronary artery disease (CAD) are two of the most common causes of death, and they frequently coexist, especially as the world's population ages. CAD can develop prior to or following cancer diagnosis, as well as a side effect of cancer treatment. CAD develops as complex interactions of lifestyle and hereditary variables, just like the development of the most complex and non-communicable diseases. Cancer is caused by both external/acquired factors (tobacco, food, physical activity, alcohol consumption, epigenetic alterations) and internal/inherited factors (genetic mutations, hormones, and immunological diseases). The Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR)-associated protein 9 (Cas9) system has recently emerged as a strong tool for gene therapy for both cancer as well as CAD treatment due to its great accuracy and efficiency. A deeper understanding of the complex link between CAD and cancer should lead to better prevention, faster detection, and safer treatment strategies.

Abstract
There has been huge progress in the discovery of targeted cancer therapies in recent years. However, even for the most successful and impactful cancer drugs which have been approved, both innate and acquired mechanisms of resistance are commonplace. These emerging mechanisms of resistance have been studied intensively, which has enabled drug discovery scientists to learn how it may be possible to overcome such resistance in subsequent generations of treatments. In some cases, novel drug candidates have been able to supersede previously approved agents; in other cases they have been used sequentially or in combinations with existing treatments. This review summarizes the current field in terms of the challenges and opportunities that cancer resistance presents to drug discovery scientists, with a focus on small molecule therapeutics. As part of this review, common themes and approaches have been identified which have been utilized to successfully target emerging mechanisms of resistance. This includes the increase in target potency and selectivity, alternative chemical scaffolds, change of mechanism of action (covalents, PROTACs), increases in blood-brain barrier permeability (BBBP), and the targeting of allosteric pockets. Finally, wider approaches are covered such as monoclonal antibodies (mAbs), bispecific antibodies, antibody drug conjugates (ADCs), and combination therapies.

Abstract
Estrogen-receptor-beta (ERβ), progesterone receptor (PR) and vascular endothelial growth factor (VEGF-A) have been implicated in colorectal cancer. However, the clinicopathological significance of any expression of these markers remains unclear. Immunohistochemical assays of ERα, ERβ, PR, and VEGF-A were performed on 72 colorectal cancer cases. Normal mucosa from the same cases was assessed as a control. The correlation of presence of these markers with clinicopathological features and survival was determined. ERα and PR were not expressed in tumors. Forty-one of 53 (77.4%) cases of normal mucosa showed strong ERβ expression compared with weak expression in 32 of 72 (44.4%) of malignant cells. A significant decrease in ERβ expression from normal mucosa to tumor was found in females ( P = 0.007) but not in males ( P = 0.149). VEGF-A was expressed strongly in malignant cells in 64 of 72 (89%) cases. No association was found between ERβ or VEGF-A expression and tumor grade, angiolymphatic involvement, stage, disease-free survival, or overall survival. Colorectal cancers do not express ERα or PR. ERβ may have a protective role, especially in females. VEGF-A may have a role in tumorigenesis. Nevertheless, ERβ and VEGF-A cannot be used as prognostic markers.

Abstract
Background The American Cancer Society, Centers for Disease Control and Prevention, National Cancer Institute, and North American Association of Central Cancer Registries provide annual updates on cancer occurrence and trends by cancer type, sex, race, ethnicity, and age in the United States. This year’s report highlights the cancer burden among men and women age 20–49 years. Methods Incidence data for the years 1999 to 2015 from the Centers for Disease Control and Prevention- and National Cancer Institute–funded population-based cancer registry programs compiled by the North American Association of Central Cancer Registries and death data for the years 1999 to 2016 from the National Vital Statistics System were used. Trends in age-standardized incidence and death rates, estimated by joinpoint, were expressed as average annual percent change. Results Overall cancer incidence rates (per 100 000) for all ages during 2011–2015 were 494.3 among male patients and 420.5 among female patients; during the same time period, incidence rates decreased 2.1% (95% confidence interval [CI] = −2.6% to −1.6%) per year in men and were stable in females. Overall cancer death rates (per 100 000) for all ages during 2012–2016 were 193.1 among male patients and 137.7 among female patients. During 2012–2016, overall cancer death rates for all ages decreased 1.8% (95% CI = −1.8% to −1.8%) per year in male patients and 1.4% (95% CI = −1.4% to −1.4%) per year in females. Important changes in trends were stabilization of thyroid cancer incidence rates in women and rapid declines in death rates for melanoma of the skin (both sexes). Among adults age 20–49 years, overall cancer incidence rates were substantially lower among men (115.3 per 100 000) than among women (203.3 per 100 000); cancers with the highest incidence rates (per 100 000) among men were colon and rectum (13.1), testis (10.7), and melanoma of the skin (9.8), and among women were breast (73.2), thyroid (28.4), and melanoma of the skin (14.1). During 2011 to 2015, the incidence of all invasive cancers combined among adults age 20–49 years decreased −0.7% (95% CI = −1.0% to −0.4%) among men and increased among women (1.3%, 95% CI = 0.7% to 1.9%). The death rate for (per 100 000) adults age 20–49 years for all cancer sites combined during 2012 to 2016 was 22.8 among men and 27.1 among women; during the same time period, death rates decreased 2.3% (95% CI = −2.4% to −2.2%) per year among men and 1.7% (95% CI = −1.8% to −1.6%) per year among women. Conclusions Among people of all ages and ages 20–49 years, favorable as well as unfavorable trends in site-specific cancer incidence were observed, whereas trends in death rates were generally favorable. Characterizing the cancer burden may inform research and cancer-control efforts.

Abstract
The putative oncogenic role of ATP/GTP binding protein like 2 (AGBL2) in catalyzing α-tubulin detyrosination has recently been characterized in cancer. However, the status of AGBL2 expression in ovarian cancer and its potential clinical and prognostic significance remain unclear. In the present study, immunohistochemistry staining investigated the protein expression level of AGBL2 in paraffin-embedded pathological specimens from 30 normal ovaries, 35 ovarian cystadenomas, 38 borderline ovarian tumors and 165 invasive ovarian carcinomas. The association between AGBL2 expression and clinicopathological characteristics of patients was evaluated using the χ2 test or Fisher's exact test. The survival status of patients was assessed by receiver-operator curve analysis. The results demonstrated that high expression of AGBL2 was observed in 9% of cystadenomas cases, 21% of borderline tumors cases and 38% of ovarian carcinomas cases; however AGBL2 expression was not high in normal ovarian tissues (P<0.01). Furthermore, the results demonstrated that high expression of AGBL2 was associated with tumor histological grade, advanced pT/pN/pM and cancer stage according to the International Federation of Gynecology and Obstetrics (P<0.05). Following univariate survival analysis of the ovarian carcinoma groups, high expression of AGBL2 was significantly associated with shorter patient survival (P<0.001). In addition, multivariate analysis revealed that AGBL2 could be identified as a potential independent prognostic factor for overall survival in patients with ovarian carcinoma (P=0.004). Furthermore, the results demonstrated that AGBL2 expression was significantly associated with the expression of immunity related GTPase M (IRGM) (P=0.013) and LC3A/B (P=0.004). IRGM expression level was also significantly associated with LC3A/B expression level (P=0.023). These findings demonstrated that AGBL2 expression was high in ovarian carcinomas, which suggested that AGBL2 may participate in the acquisition of an aggressive phenotype and may therefore serve as an independent prognostic molecular marker.

Abstract
BACKGROUND The purpose of our analysis was to compare the results of treatment in patients who underwent resection for colorectal carcinoma. METHODS In the period from 1/1/1991 to 31/12/2000 1478 patients with colorectal carcinoma underwent potentially curative resection. We divided them into two 5-year period groups according to different treatment regimes. The 5-year net survival rate was estimated, where the net survival is the probability of survival derived solely from the cancer-specific hazard. RESULTS In a 10-year period, we resected 1478 patients. The 5-year net survival rate for R0-resected patients with colon cancer increased from 76.3 to 85.2% between the periods 1991-1995 and 1995-2000. The 5-year net survival rate for R0-resected patients with rectal cancer also increased from 67.5 to 73% in the same period. CONCLUSION A comparison of the 5-year net survival rate for R0-resected patients with colorectal cancer increased in the last period from 1995 to 2000 compared with the period from 1991 to 1995. In multivariate analysis, early stage at diagnosis and adjuvant chemotherapy was both associated with better net survival after surgery with curative intent. The improvement of net survival is potentially the result of combination of better surgical and adjuvant therapy.

Abstract
OBJECTIVE The aim of the study was to determine factors associated with the development of cervical malignancy among women participating in an organized cervical screening program. MATERIALS AND METHODS A population-based retrospective cohort study was performed examining the screening histories 2 to 10 years before diagnosis of invasive cancer in Ontario women between 2011 and 2014. RESULTS A total of 2,002 cases of cervical cancer were identified; 1,358 (68%) were squamous cell carcinomas and 644 (32%) were adenocarcinomas. The mean age at the time of diagnosis was 50.3 years. More than 60% of the cohort had at least 1 cytology test within 2 to 10 years of their diagnosis. Of the women having a cytology result 24 to 36 months before diagnosis, 69% had a normal cytology whereas only 7% had a high-grade cytology result. Stage of cancer was most advanced in women who did not have cytology in the 2 to 10 years before their diagnosis. On multivariate regression, those with cervical cancer who were less likely to have undergone screening include older age, advanced stage, lower income, not having a family physician, and those diagnosed with adenocarcinoma. CONCLUSIONS Although nonparticipation in screening is the greatest factor associated with cervical cancer diagnosis, failure of cervical cytology to detect cytologic abnormalities in women 2 to 3 and 3 to 5 years before diagnosis is of concern. Efforts must be directed to recruitment of women for screening as well as improving the sensitivity of screening tests to detect existing abnormalities.

Annual Report to the Nation on the Status of Cancer, part I: National cancer statistics. Cancer 2018; 124:2785-2800. [PMID: 29786848 PMCID: PMC6033186 DOI: 10.1002/cncr.31551] [Citation(s) in RCA: 756] [Impact Index Per Article: 126.0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/22/2018] [Revised: 04/23/2018] [Accepted: 04/26/2018] [Indexed: 12/18/2022]
Abstract
BACKGROUND The American Cancer Society (ACS), the Centers for Disease Control and Prevention (CDC), the National Cancer Institute (NCI), and the North American Association of Central Cancer Registries (NAACCR) collaborate to provide annual updates on cancer occurrence and trends in the United States. METHODS Incidence data were obtained from the CDC-funded and NCI-funded population-based cancer registry programs and compiled by NAACCR. Data on cancer deaths were obtained from the National Center for Health Statistics National Vital Statistics System. Trends in age-standardized incidence and death rates for all cancers combined and for the leading cancer types by sex, race, and ethnicity were estimated by joinpoint analysis and expressed as the annual percent change. Stage distribution and 5-year survival by stage at diagnosis were calculated for breast cancer, colon and rectum (colorectal) cancer, lung and bronchus cancer, and melanoma of the skin. RESULTS Overall cancer incidence rates from 2008 to 2014 decreased by 2.2% per year among men but were stable among women. Overall cancer death rates from 1999 to 2015 decreased by 1.8% per year among men and by 1.4% per year among women. Among men, incidence rates during the most recent 5-year period (2010-2014) decreased for 7 of the 17 most common cancer types, and death rates (2011-2015) decreased for 11 of the 18 most common types. Among women, incidence rates declined for 7 of the 18 most common cancers, and death rates declined for 14 of the 20 most common cancers. Death rates decreased for cancer sites, including lung and bronchus (men and women), colorectal (men and women), female breast, and prostate. Death rates increased for cancers of the liver (men and women); pancreas (men and women); brain and other nervous system (men and women); oral cavity and pharynx (men only); soft tissue, including heart (men only); nonmelanoma skin (men only); and uterus. Incidence and death rates were higher among men than among women for all racial and ethnic groups. For all cancer sites combined, black men and white women had the highest incidence rates compared with other racial groups, and black men and black women had the highest death rates compared with other racial groups. Non-Hispanic men and women had higher incidence and mortality rates than those of Hispanic ethnicity. Five-year survival for cases diagnosed from 2007 through 2013 ranged from 100% (stage I) to 26.5% (stage IV) for female breast cancer, from 88.1% (stage I) to 12.6% (stage IV) for colorectal cancer, from 55.1% (stage I) to 4.2% (stage IV) for lung and bronchus cancer, and from 99.5% (stage I) to 16% (stage IV) for melanoma of the skin. Among children, overall cancer incidence rates increased by 0.8% per year from 2010 to 2014, and overall cancer death rates decreased by 1.5% per year from 2011 to 2015. CONCLUSIONS For all cancer sites combined, cancer incidence rates decreased among men but were stable among women. Overall, there continue to be significant declines in cancer death rates among both men and women. Differences in rates and trends by race and ethnic group remain. Progress in reducing cancer mortality has not occurred for all sites. Examining stage distribution and 5-year survival by stage highlights the potential benefits associated with early detection and treatment. Cancer 2018;124:2785-2800. © 2018 American Cancer Society.

Abstract
In this prospective study we have quantified by means of ELISA-methods the cytosolic content of estrogen (ER) and progesterone receptors (PgR) in tumoral tissue and paired normal mucosa from 163 patients with resectable colorectal cancer. Survival analysis was performed in a subgroup of 120 patients and the mean follow-up period was 24.9 months. The cutoff for ER and PgR levels was set at 1 fmol/mg protein. On the basis of this cutoff 20.9% of the cancers were ER positive and 25.8% were PgR positive; normal adjacent tissue presented ER in 18.4% and PgR in 24.5%. Our results did not show any significant correlation between ER and PgR levels in neoplastic tissues. Howewer, a correlation was found in normal mucosa samples (p=0.02). Statistical analysis showed that there was no correlation between tumor ER and PgR content and patient age or sex, tumor location, Dukes’ stage, histological differentiation, DNA ploidy status and S-phase fraction. Furthermore, the results did not show any statistical differences in relapse-free and overall survival curves calculated for patients classified according to the hormone receptor content of their tumors. ER and PgR were detected at low levels in normal and neoplastic colorectal tissues without any significant relationship to either clinicopathological tumor characteristics or patient outcome. Their possible role in colorectal cancer remains to be elucidated.

Abstract
Objectives Evaluate clinicopathologic factors contributing to regional lymph node (LN) metastases in cutaneous head and neck melanoma (HNM). Study Design Retrospective review of a national cancer database. Setting National Cancer Database (2004-2012). Methods National Cancer Database (NCDB) cases diagnosed between 2004 and 2012 were reviewed. Inclusion criteria were head and neck cutaneous site codes, melanoma histology codes, and clinically node-negative status. Independent, clinicopathologic factors associated with pathologic positive LN status were identified by multivariable logistic regression. Subset analysis was performed on thin melanoma cases of 0.75 to 1 mm tumor depth to determine factors predictive of LN involvement and survival. Results Of 66,495 cases meeting inclusion criteria, 18,882 had nodes examined pathologically with 9.7% presenting with occult positive LN involvement. Mean (SD) age was 62.9 (16.13) years, and primary sites were scalp and neck (42.2%), face (40.2%), and external ear, lip, or eyelid (7.6%). Multivariable analysis found younger age; primary site of cutaneous scalp, neck, or face; increasing thickness; mitoses; ulceration; and vertical growth phase presence were independently associated with LN positivity ( P < .001). Only 2% of 0.75- to 1.0-mm Breslow thickness cases had regional LN involvement, and age >70 was negatively associated with LN involvement ( P = .002) in this subset. Conclusion This is the largest study examining factors predictive of occult LN involvement in patients with clinical node-negative cutaneous HNM who may benefit from sentinel LN biopsy. Primary sites of external ear, lip, or eyelid are less likely to present with occult nodal involvement, and older patients with T1a melanoma ≥0.76 mm are unlikely to present with regional node metastasis and may not require sentinel node guided management.

Abstract
Atherosclerosis and cancer are chronic diseases considered two of the main causes of death all over the world. Taking into account that both diseases are multifactorial, they share not only several important molecular pathways but also many ethiological and mechanistical processes from the very early stages of development up to the advanced forms in both pathologies. Factors involved in their progression comprise genetic alterations, inflammatory processes, uncontrolled cell proliferation and oxidative stress, as the most important ones. The fact that external effectors such as an infective process or a chemical insult have been proposed to initiate the transformation of cells in the artery wall and the process of atherogenesis, emphasizes many similarities with the progression of the neoplastic process in cancer. Deregulation of cell proliferation and therefore cell cycle progression, changes in the synthesis of important transcription factors as well as adhesion molecules, an alteration in the control of angiogenesis and the molecular similarities that follow chronic inflammation, are just a few of the processes that become part of the phenomena that closely correlates atherosclerosis and cancer. The aim of the present study is therefore, to provide new evidence as well as to discuss new approaches that might promote the identification of closer molecular ties between these two pathologies that would permit the recognition of atherosclerosis as a pathological process with a very close resemblance to the way a neoplastic process develops, that might eventually lead to novel ways of treatment.

Abstract
Background: The American Cancer Society (ACS), the Centers for Disease Control and Prevention (CDC), the National Cancer Institute (NCI), and the North American Association of Central Cancer Registries (NAACCR) collaborate to provide annual updates on cancer occurrence and trends in the United States. This Annual Report highlights survival rates. Methods: Data were from the CDC- and NCI-funded population-based cancer registry programs and compiled by NAACCR. Trends in age-standardized incidence and death rates for all cancers combined and for the leading cancer types by sex were estimated by joinpoint analysis and expressed as annual percent change. We used relative survival ratios and adjusted relative risk of death after a diagnosis of cancer (hazard ratios [HRs]) using Cox regression model to examine changes or differences in survival over time and by sociodemographic factors. Results: Overall cancer death rates from 2010 to 2014 decreased by 1.8% (95% confidence interval [CI] = –1.8 to –1.8) per year in men, by 1.4% (95% CI = –1.4 to –1.3) per year in women, and by 1.6% (95% CI = –2.0 to –1.3) per year in children. Death rates decreased for 11 of the 16 most common cancer types in men and for 13 of the 18 most common cancer types in women, including lung, colorectal, female breast, and prostate, whereas death rates increased for liver (men and women), pancreas (men), brain (men), and uterine cancers. In contrast, overall incidence rates from 2009 to 2013 decreased by 2.3% (95% CI = –3.1 to –1.4) per year in men but stabilized in women. For several but not all cancer types, survival statistically significantly improved over time for both early and late-stage diseases. Between 1975 and 1977, and 2006 and 2012, for example, five-year relative survival for distant-stage disease statistically significantly increased from 18.7% (95% CI = 16.9% to 20.6%) to 33.6% (95% CI = 32.2% to 35.0%) for female breast cancer but not for liver cancer (from 1.1%, 95% CI = 0.3% to 2.9%, to 2.3%, 95% CI = 1.6% to 3.2%). Survival varied by race/ethnicity and state. For example, the adjusted relative risk of death for all cancers combined was 33% (HR = 1.33, 95% CI = 1.32 to 1.34) higher in non-Hispanic blacks and 51% (HR = 1.51, 95% CI = 1.46 to 1.56) higher in non-Hispanic American Indian/Alaska Native compared with non-Hispanic whites. Conclusions: Cancer death rates continue to decrease in the United States. However, progress in reducing death rates and improving survival is limited for several cancer types, underscoring the need for intensified efforts to discover new strategies for prevention, early detection, and treatment and to apply proven preventive measures broadly and equitably.

Abstract
Growth factor receptor-bound protein-2 (Grb2) can act as the scaffold protein recruiting other molecules to the stimulated receptors. Grb2-associated binding protein 1 (Gab1) is involved in cell proliferation, and its expression may enhance the carcinogenesis and cancer progression. However, the function of Gab1 remains to be investigated. Epithelial ovarian cancer (EOC) is the most lethal malignancy in the female reproductive system with increasing incidence and unsatisfied overall survival (OS). We investigated the expression of Gab1 in EOC tissues and the correlations between Gab1 expression and the clinicopathological characteristics of patients with EOC using Spearman rank test. The staining results were evaluated based on both the percentage of Gab1-positive tumor cells and the staining intensity for Gab1 expression. Kaplan-Meier survival analysis and Cox proportional hazards analysis were used to compare the postoperative OS between EOC patients with high Gab1 expression and those with low Gab1 expression. The high expression of Gab1 was positively correlated with advanced FIGO stage and lymph node metastasis of EOC. Univariate analysis showed that advanced FIGO stage, pathological grade, lymph node metastasis or Gab1 expression were associated with poor OS. Moreover, multivariate analysis revealed that Gab1 expression could be an independent prognostic factor for the poor OS of EOC patients (P = 0.042). We propose that Gab1 expression is correlated with poor prognosis of EOC patients and may act as an independent prognostic indicator.

Abstract
OBJECTIVE To evaluate reproductive hormone patterns in women exposed to alkylating-agent chemotherapy. DESIGN Prospective cohort. SETTING University hospital. PATIENT(S) Normally menstruating mid-reproductive-age women (20-35 years old) who had previously been exposed to alkylating-agent chemotherapy for cancer treatment were compared with two healthy control populations: similarly-aged women and late-reproductive-age women (43-50 years old). INTERVENTION(S) Subjects collected daily urine samples for one cycle. MAIN OUTCOME MEASURE(S) Integrated urinary pregnanediol glucuronide (PDG) and estrone conjugate (E1c) and urinary excretion of gonadotropins (FSH and LH). RESULT(S) Thirty-eight women (13 survivors, 11 same-age control subjects, 14 late-reproductive-age control subjects) provided 1,082 urine samples. Cycle length, luteal phase length, and evidence of luteal activity were similar among the groups. As expected, ovarian reserve was impaired in cancer survivors compared with same-age control subjects but similar between survivors and late-reproductive-age control subjects. In contrast, survivors had total and peak PDG levels that were similar to same-age control subjects and higher than those observed in late-reproductive-age control subjects. Survivors had higher E1c levels than both same-age and late-reproductive-age control subjects. There was no difference in urinary gonadotropins among the groups. CONCLUSION(S) Women exposed to alkylating agents have a unique reproductive hormone milieu that is not solely explained by age or ovarian reserve. The urinary hormone profile observed in survivors appears more similar to same-age control subjects than to late-reproductive-age women with similar ovarian reserve, which may suggest that age plays a more important role than ovarian reserve in the follicular dynamics of survivors.

Abstract
Post-therapeutic surveillance is one important component of cancer care. However, there still is no evidence-based strategies to schedule patients’ follow-up examinations. Our approach is based on the modeling of the probability of the onset of relapse at an early asymptotic or preclinical stage and its transition to a clinical stage. For that we consider a multistate homogeneous Markov model, which includes the natural history of relapse. The model also handles separately the different types of possible relapses. The optimal schedule is provided by the calendar visit that maximizes a utility function. The methodology has been applied to laryngeal cancer. The different follow-up strategies revealed to be more efficient than those proposed by different scientific societies.

Abstract
A fundamental component of community-based health promotion efforts to eliminate disparities is the mobilization of community involvement to address not only individual but also systemic and political causes of inequalities in health. The participatory action research (PAR) paradigm is well suited to address these multilevel inequalities in research and evaluation experienced by many ethnic and racial communities. In this article, a case study of a project to reduce health disparities in breast and cervical cancer among seven Southeast Asian and Pacific Islander communities in Southern California is presented. The authors applied a PAR framework to the process of needs assessment and program planning to understand and address the complex and multilevel factors that contribute to the problem of disparate breast and cervical cancer screening rates in these communities. Finally, the authors describe the lessons that were learned about how to promote collaborative research as an essential element in the design of projects and studies to address ethnic disparities in health outcomes for breast and cervical cancer.

The potential effect of age on the natural behavior of bladder cancer: Does urothelial cell carcinoma progress differently in various age groups? Kaohsiung J Med Sci 2016; 32:261-6. [PMID: 27316585 DOI: 10.1016/j.kjms.2016.03.002] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/04/2015] [Revised: 01/22/2016] [Accepted: 03/01/2016] [Indexed: 01/01/2023] Open
Abstract
We aimed to evaluate the potential effect of age on the natural behavior of bladder cancer and to compare these findings between different age groups. The clinical and pathologic data of 239 patients treated at our institution between 1994 and 2014 were analyzed. The patients were classified into three groups according to age: ≤ 40 years (Group 1), 41-59 years (Group 2), and ≥ 60 years (Group 3). The following data were collected: characteristics of the patients, initial pathological findings after transurethral resection, tumor stage and grade, tumor size and multiplicity, and disease recurrence and progression. The mean age of the patients at initial diagnosis was 34.2±5.5 years, 53±5.1 years, and 71.1±7 years in Groups 1, 2, and 3, respectively. There were 207 (86.6%) patients with nonmuscle-invasive urothelial bladder cancer and 32 (13.4%) patients with muscle-invasive disease. Tumor recurrence was significantly lower in Group 1 than in Group 2 (p=0.001) and Group 3 (p=0.001). Although the time to tumor recurrence was significantly different between the three groups (p=0.001), no significant difference was noted in the time to progression (p=0.349). Patients with urothelial cancer younger than 40 years tend to have single and small tumors. The tumor recurrence rate is lower in the younger age group, but tumor progression is similar in older and younger patients. Therefore, the findings indicate that clinicians should be careful when assessing the invasiveness of urothelial tumors in younger patients and start treatment as soon as possible.

Abstract
Abstract
We estimate the marginal benefits of population-based cancer screening by comparing cancer test and detection rates on either side of US guideline-recommended initiation ages (age 40 for breast cancer and age 50 for colorectal cancer during the study period). Using a regression discontinuity design and self-reported test data from national health surveys, we find test rates for breast and colorectal cancer increase at the guideline age thresholds by 109% and 78%, respectively. Data from cancer registries in twelve US states indicate that cancer detection rates increase at the same thresholds by 50% and 49%, respectively. We estimate significant effects of screening on earlier breast cancer detection (1.2 cases/1000 screened) at age 40 and colorectal cancer detection (1.1 cases/1000 individuals screened) at age 50. Forty-eight and 73% of the increases in breast and colorectal case detection occur among middle-stage cancers (localized and regional) with most of the remainder among early-stage (in-situ). Our analysis suggests that the cost of detecting an asymptomatic case of breast cancer at age 40 via population-based screening is $107,000–134,000 and that the cost of detecting an asymptomatic case of colorectal cancer at age 50 is $473,000–485,000.

Annual Report to the Nation on the Status of Cancer, 1975-2012, featuring the increasing incidence of liver cancer. Cancer 2016; 122:1312-37. [PMID: 26959385 PMCID: PMC4840031 DOI: 10.1002/cncr.29936] [Citation(s) in RCA: 656] [Impact Index Per Article: 82.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/08/2016] [Accepted: 01/21/2016] [Indexed: 02/06/2023]
Abstract
BACKGROUND Annual updates on cancer occurrence and trends in the United States are provided through an ongoing collaboration among the American Cancer Society (ACS), the Centers for Disease Control and Prevention (CDC), the National Cancer Institute (NCI), and the North American Association of Central Cancer Registries (NAACCR). This annual report highlights the increasing burden of liver and intrahepatic bile duct (liver) cancers. METHODS Cancer incidence data were obtained from the CDC, NCI, and NAACCR; data about cancer deaths were obtained from the CDC's National Center for Health Statistics (NCHS). Annual percent changes in incidence and death rates (age-adjusted to the 2000 US Standard Population) for all cancers combined and for the leading cancers among men and women were estimated by joinpoint analysis of long-term trends (incidence for 1992-2012 and mortality for 1975-2012) and short-term trends (2008-2012). In-depth analysis of liver cancer incidence included an age-period-cohort analysis and an incidence-based estimation of person-years of life lost because of the disease. By using NCHS multiple causes of death data, hepatitis C virus (HCV) and liver cancer-associated death rates were examined from 1999 through 2013. RESULTS Among men and women of all major racial and ethnic groups, death rates continued to decline for all cancers combined and for most cancer sites; the overall cancer death rate (for both sexes combined) decreased by 1.5% per year from 2003 to 2012. Overall, incidence rates decreased among men and remained stable among women from 2003 to 2012. Among both men and women, deaths from liver cancer increased at the highest rate of all cancer sites, and liver cancer incidence rates increased sharply, second only to thyroid cancer. Men had more than twice the incidence rate of liver cancer than women, and rates increased with age for both sexes. Among non-Hispanic (NH) white, NH black, and Hispanic men and women, liver cancer incidence rates were higher for persons born after the 1938 to 1947 birth cohort. In contrast, there was a minimal birth cohort effect for NH Asian and Pacific Islanders (APIs). NH black men and Hispanic men had the lowest median age at death (60 and 62 years, respectively) and the highest average person-years of life lost per death (21 and 20 years, respectively) from liver cancer. HCV and liver cancer-associated death rates were highest among decedents who were born during 1945 through 1965. CONCLUSIONS Overall, cancer incidence and mortality declined among men; and, although cancer incidence was stable among women, mortality declined. The burden of liver cancer is growing and is not equally distributed throughout the population. Efforts to vaccinate populations that are vulnerable to hepatitis B virus (HBV) infection and to identify and treat those living with HCV or HBV infection, metabolic conditions, alcoholic liver disease, or other causes of cirrhosis can be effective in reducing the incidence and mortality of liver cancer.

Abstract
BACKGROUND Although colorectal cancer (CRC) mortality rates are declining, racial-ethnic disparities in CRC mortality nationally are widening. Herein, the authors attempted to identify county-level variations in this pattern, and to characterize counties with improving disparity trends. METHODS The authors examined 20-year trends in US county-level black-white disparities in CRC age-adjusted mortality rates during the study period between 1989 and 2010. Using a mixed linear model, counties were grouped into mutually exclusive patterns of black-white racial disparity trends in age-adjusted CRC mortality across 20 three-year rolling average data points. County-level characteristics from census data and from the Area Health Resources File were normalized and entered into a principal component analysis. Multinomial logistic regression models were used to test the relation between these factors (clusters of related contextual variables) and the disparity trend pattern group for each county. RESULTS Counties were grouped into 4 disparity trend pattern groups: 1) persistent disparity (parallel black and white trend lines); 2) diverging (widening disparity); 3) sustained equality; and 4) converging (moving from disparate outcomes toward equality). The initial principal component analysis clustered the 82 independent variables into a smaller number of components, 6 of which explained 47% of the county-level variation in disparity trend patterns. CONCLUSIONS County-level variation in social determinants, health care workforce, and health systems all were found to contribute to variations in cancer mortality disparity trend patterns from 1990 through 2010. Counties sustaining equality over time or moving from disparities to equality in cancer mortality suggest that disparities are not inevitable, and provide hope that more communities can achieve optimal and equitable cancer outcomes for all.

Abstract
The objective of the present study was to investigate the incidence of and possible risk factors associated with sarcopenia among cancer patients. Patients with cancer were examined through the use of lumbar magnetic resonance imaging, and clinical data was collected between September and December, 2012, at Jilin Province Tumor Hospital (Changchun, China). The data was subsequently compared between patients with and without sarcopenia. Of the 113 treated cancer patients, 96 patients [39 males (L3 index, <52.4 cm2/m2) and 57 females (L3 index, <38.5 cm2/m2)] suffered from sarcopenia. Overall, the development of sarcopenia was not significantly associated with patient age or treatment, including surgery, chemotherapy or radiotherapy (P>0.05). The frequency of treatment-associated complications did not differ significantly between patients with or without sarcopenia. However, males were more inclined to develop sarcopenia than females (P=0.02). Patients with sarcopenia had significantly less lymphocytes than patients without sarcopenia (P=0.03). This was confirmed through multiple logistic regression analyses (P=0.046), which also identified that patients with cancer with an Eastern Cooperative Oncology Group score >2 had a significantly increased risk of developing sarcopenia. Finally, the serum albumin level in sarcopenia patients was 36.18±4.65 g/l, which was not significantly less than that of patients without sarcopenia (39.67±3.69 g/l; P=0.11). The incidence of sarcopenia among patients with cancer is high, particularly for males. Further research with larger sample sizes would be beneficial, with the aim of verifying the results obtained in the present study. During the treatment of patients with sarcopenia, precaution should continue to be taken to prevent associated complications, including infection, diarrhea and myelosuppression.

Abstract
Background In a previous analysis on the patients with ovarian cancers, we have found that clusterin is a biomarker associated with ovarian cancer in vivo and may be a prognostic factor associated with adverse outcome. Here, we explored the effect of lentivirus-mediated shRNA interference of clusterin, investigated whether clusterin was associated with adverse outcome of ovarian cancer cells in vitro. Methods OVCAR-3 and TOV-21G cell lines were infected with the lentivirus for delivering clusterin shRNA, and the stably transfected cells were selected. The effect of clusterin silencing was detected by western blotting assay. The proliferation, clonability, migration, invasion and cell cycle of two cell lines were detected separately by MTT assay, clone formation assay, scratch assay, transwell assay and fluorescence-activated cell sorting. Results Following clusterin silencing with shRNA, the expression of clusterin in two cell lines were decreased. And the proliferation, clonability, migration, invasion of these two cell lines were down-regulated apparently. The cell cycle of two cell lines was disturbed, cells in G1 phase was increased, but cells in G2 and S phase was decreased. Conclusions The expression of clusterin is significantly correlated with the biological characteristics of ovarian cancer cells, it may be a potential molecular for ovarian cancer treatment.

Abstract
BACKGROUND The American Cancer Society (ACS), Centers for Disease Control and Prevention (CDC), National Cancer Institute (NCI), and North American Association of Central Cancer Registries (NAACCR) collaborate annually to produce updated, national cancer statistics. This Annual Report includes a focus on breast cancer incidence by subtype using new, national-level data. METHODS Population-based cancer trends and breast cancer incidence by molecular subtype were calculated. Breast cancer subtypes were classified using tumor biomarkers for hormone receptor (HR) and human growth factor-neu receptor (HER2) expression. RESULTS Overall cancer incidence decreased for men by 1.8% annually from 2007 to 2011 [corrected]. Rates for women were stable from 1998 to 2011. Within these trends there was racial/ethnic variation, and some sites have increasing rates. Among children, incidence rates continued to increase by 0.8% per year over the past decade while, like adults, mortality declined. HR+/HER2- breast cancers, the subtype with the best prognosis, were the most common for all races/ethnicities with highest rates among non-Hispanic white women, local stage cases, and low poverty areas (92.7, 63.51, and 98.69 per 100000 non-Hispanic white women, respectively). HR+/HER2- breast cancer incidence rates were strongly, positively correlated with mammography use, particularly for non-Hispanic white women (Pearson 0.57, two-sided P < .001). Triple-negative breast cancers, the subtype with the worst prognosis, were highest among non-Hispanic black women (27.2 per 100000 non-Hispanic black women), which is reflected in high rates in southeastern states. CONCLUSIONS Progress continues in reducing the burden of cancer in the United States. There are unique racial/ethnic-specific incidence patterns for breast cancer subtypes; likely because of both biologic and social risk factors, including variation in mammography use. Breast cancer subtype analysis confirms the capacity of cancer registries to adjust national collection standards to produce clinically relevant data based on evolving medical knowledge.

Abstract
Ovarian cancer is a solid tumor and a leading cause of mortality. Diagnostic tools for the detection of early stage (stage I) ovarian cancer are urgently needed. For this purpose, attenuated total reflection Fourier-transform infrared spectroscopy (ATR-FTIR) coupled with variable selection methods, successive projection algorithm or genetic algorithm (GA) combined with linear discriminant analysis (LDA), were employed to identify spectral biomarkers in blood plasma or serum samples for accurate diagnosis of different stages of ovarian cancer, histological type and segregation based on age. Three spectral datasets (stage I vs. stage II-IV; serous vs. non-serous carcinoma; and, ≤60 years vs. >60 years) were processed: sensitivity and specificity required for real-world diagnosis of ovarian cancer was achieved. Toward segregating stage I vs. stage II-IV, sensitivity and specificity (plasma blood) of 100% was achieved using a GA-LDA model with 33 wavenumbers. For serous vs. non-serous category (plasma blood), the sensitivity and specificity levels, using 29 wavenumbers by GA-LDA, were remarkable (up to 94%). For ≤60 years and >60 years categories (plasma blood), the sensitivity and specificity, using 42 wavenumbers by GA-LDA, gave complete accuracy (100%). For serum samples, sensitivity and specificity results gave relatively high accuracy (up to 91.6% stage I vs. stage II-IV; up to 93.0% serous vs. non-serous; and, up to 96.0% ≤60 years vs. >60 years) using several wavenumbers. These findings justify a prospective population-based assessment of biomarkers signatures using ATR-FTIR spectroscopy as a screening tool for stage of ovarian cancer.

Abstract
Cancer is the leading cause of death for Asian Americans, and breast cancer is the leading cancer diagnosed among Asian American women. Despite the alarming facts, Asian American women have low breast cancer screening rates. This study examined the effects of a culturally appropriate community-based breast intervention program on participants' knowledge about breast cancer and intention for screening among Southeast Asian and South Asian women in Michigan. Data were collected from 166 women. At baseline, participants had limited knowledge of breast cancer screening guidelines and misconceptions about the risk factors of breast cancer. After the educational intervention, participants reported significantly higher knowledge scores related to breast cancer and screening recommendations and intentions to obtain follow-up CBE and mammograms. This culturally appropriate intervention provides strategies to overcome personal instructional barriers to meet the needs of this group for early detection and cancer control.

Abstract
BACKGROUND The American Cancer Society (ACS), the Centers for Disease Control and Prevention (CDC), the National Cancer Institute (NCI), and the North American Association of Central Cancer Registries (NAACCR) collaborate annually to provide updates on cancer incidence and death rates and trends in these outcomes for the United States. This year's report includes the prevalence of comorbidity at the time of first cancer diagnosis among patients with lung, colorectal, breast, or prostate cancer and survival among cancer patients based on comorbidity level. METHODS Data on cancer incidence were obtained from the NCI, the CDC, and the NAACCR; and data on mortality were obtained from the CDC. Long-term (1975/1992-2010) and short-term (2001-2010) trends in age-adjusted incidence and death rates for all cancers combined and for the leading cancers among men and women were examined by joinpoint analysis. Through linkage with Medicare claims, the prevalence of comorbidity among cancer patients who were diagnosed between 1992 through 2005 residing in 11 Surveillance, Epidemiology, and End Results (SEER) areas were estimated and compared with the prevalence in a 5% random sample of cancer-free Medicare beneficiaries. Among cancer patients, survival and the probabilities of dying of their cancer and of other causes by comorbidity level, age, and stage were calculated. RESULTS Death rates continued to decline for all cancers combined for men and women of all major racial and ethnic groups and for most major cancer sites; rates for both sexes combined decreased by 1.5% per year from 2001 through 2010. Overall incidence rates decreased in men and stabilized in women. The prevalence of comorbidity was similar among cancer-free Medicare beneficiaries (31.8%), breast cancer patients (32.2%), and prostate cancer patients (30.5%); highest among lung cancer patients (52.9%); and intermediate among colorectal cancer patients (40.7%). Among all cancer patients and especially for patients diagnosed with local and regional disease, age and comorbidity level were important influences on the probability of dying of other causes and, consequently, on overall survival. For patients diagnosed with distant disease, the probability of dying of cancer was much higher than the probability of dying of other causes, and age and comorbidity had a smaller effect on overall survival. CONCLUSIONS Cancer death rates in the United States continue to decline. Estimates of survival that include the probability of dying of cancer and other causes stratified by comorbidity level, age, and stage can provide important information to facilitate treatment decisions.

Abstract
Background The American Cancer Society (ACS), the Centers for Disease Control and Prevention (CDC), the National Cancer Institute (NCI), and the North American Association of Central Cancer Registries (NAACCR) collaborate annually to provide updates on cancer incidence and death rates and trends in these outcomes for the United States. This year’s report includes incidence trends for human papillomavirus (HPV)–associated cancers and HPV vaccination (recommended for adolescents aged 11–12 years). Methods Data on cancer incidence were obtained from the CDC, NCI, and NAACCR, and data on mortality were obtained from the CDC. Long- (1975/1992–2009) and short-term (2000–2009) trends in age-standardized incidence and death rates for all cancers combined and for the leading cancers among men and among women were examined by joinpoint analysis. Prevalence of HPV vaccination coverage during 2008 and 2010 and of Papanicolaou (Pap) testing during 2010 were obtained from national surveys. Results Death rates continued to decline for all cancers combined for men and women of all major racial and ethnic groups and for most major cancer sites; rates for both sexes combined decreased by 1.5% per year from 2000 to 2009. Overall incidence rates decreased in men but stabilized in women. Incidence rates increased for two HPV-associated cancers (oropharynx, anus) and some cancers not associated with HPV (eg, liver, kidney, thyroid). Nationally, 32.0% (95% confidence interval [CI] = 30.3% to 33.6%) of girls aged 13 to 17 years in 2010 had received three doses of the HPV vaccine, and coverage was statistically significantly lower among the uninsured (14.1%, 95% CI = 9.4% to 20.6%) and in some Southern states (eg, 20.0% in Alabama [95% CI = 13.9% to 27.9%] and Mississippi [95% CI = 13.8% to 28.2%]), where cervical cancer rates were highest and recent Pap testing prevalence was the lowest. Conclusions The overall trends in declining cancer death rates continue. However, increases in incidence rates for some HPV-associated cancers and low vaccination coverage among adolescents underscore the need for additional prevention efforts for HPV-associated cancers, including efforts to increase vaccination coverage.

Abstract
BACKGROUND Cancer, by conferring a hypercoagulable state, may lead to an ischemic stroke. Relatively little is known about the prevalence and evolution of cancer among stroke patients over the last decade. METHODS We used the Nationwide Inpatient Sample to identify discharges with any InternationalClassification of Diseases, Ninth Revision, diagnosis code for cancer and ischemic stroke from 1997 to 2006. We then calculated age-adjusted yearly acute ischemic stroke hospitalization rates among adult populations with and without cancer. RESULTS Prevalence of cancer among hospitalized stroke patients increased from 1997 to 2006 (N = 31,075 [9.1% of all ischemic stroke hospitalizations] to 34,138 [10.6%], P < .0001). The most common types of cancer among hospitalized stroke patients in 1997 and 2006 were prostate (21% versus 19%), breast (19% versus 19%), gastrointestinal (16% versus 13%), and colorectal (13% versus 13%). Over the decade there was a significant decrease in the prevalence of stroke hospitalizations (slope -3.02, 95% confidence interval -3.69 to -2.34), but not among cancer patients (slope 1.35, 95% confidence interval -0.88 to 3.58). CONCLUSION About 1 in 10 hospitalized ischemic stroke patients in the United States has comorbid cancer, and there has been a slight rise in this rate over the last decade. This is likely due to enhanced survival from better cancer treatments, but further study is warranted.

Abstract
PURPOSE To characterize abnormal epigenetic changes and protein expression of the clusterin gene in a large series of ovarian malignant and borderline tumors. METHODS Protein expression and promoter methylation of clusterin gene in 181 primary ovarian epithelial cancer, 40 borderline ovarian tumors, 54 ovarian cancer mesenteric metastasis, and 10 normal ovarian samples were analyzed by immunohistochemical staining and methylation-specific PCR. RESULTS Overexpression of clusterin protein was frequently seen in various ovarian epithelial tumors, being detected in 102 of 181 (56 %) primary ovarian epithelial cancers, 21 of 37 (57 %) borderline ovarian tumors. Surprisingly, clusterin protein expression was significantly reduced in mesenteric metastasis (20 of 54; 37 % cases), as compared to primary ovarian carcinoma (p = 0.01). Overexpression of clusterin protein was significantly correlated with high-grade histology (p = 0.002) and high FIGO stages (p = 0.05). Clusterin promoter hypermethylation was detected in 24 of 181 (13 %) primary ovarian epithelial cancer, 8 of 54 (14 %) mesenteric metastasis, and 10 of 37 (27 %) borderline ovarian tumors. Overall, clusterin promoter hypermethylation was significantly correlated with decreased protein expression in these samples (p < 0.001). CONCLUSIONS Increased clusterin expression is correlated with more aggressive biologic behavior in ovarian cancer. Promoter methylation of the clusterin gene can be readily detected, though at low frequencies, in ovarian epithelial tumors and is significantly associated with decreased protein expression of the gene.

Abstract
BACKGROUND Annual updates on cancer occurrence and trends in the United States are provided through collaboration between the American Cancer Society (ACS), the Centers for Disease Control and Prevention (CDC), the National Cancer Institute (NCI), and the North American Association of Central Cancer Registries (NAACCR). This year's report highlights the increased cancer risk associated with excess weight (overweight or obesity) and lack of sufficient physical activity (<150 minutes of physical activity per week). METHODS Data on cancer incidence were obtained from the CDC, NCI, and NAACCR; data on cancer deaths were obtained from the CDC's National Center for Health Statistics. Annual percent changes in incidence and death rates (age-standardized to the 2000 US population) for all cancers combined and for the leading cancers among men and among women were estimated by joinpoint analysis of long-term trends (incidence for 1992-2008 and mortality for 1975-2008) and short-term trends (1999-2008). Information was obtained from national surveys about the proportion of US children, adolescents, and adults who are overweight, obese, insufficiently physically active, or physically inactive. RESULTS Death rates from all cancers combined decreased from 1999 to 2008, continuing a decline that began in the early 1990s, among men and among women in most racial and ethnic groups. Death rates decreased from 1999 to 2008 for most cancer sites, including the 4 most common cancers (lung, colorectum, breast, and prostate). The incidence of prostate and colorectal cancers also decreased from 1999 to 2008. Lung cancer incidence declined from 1999 to 2008 among men and from 2004 to 2008 among women. Breast cancer incidence decreased from 1999 to 2004 but was stable from 2004 to 2008. Incidence increased for several cancers, including pancreas, kidney, and adenocarcinoma of the esophagus, which are associated with excess weight. CONCLUSIONS Although improvements are reported in the US cancer burden, excess weight and lack of sufficient physical activity contribute to the increased incidence of many cancers, adversely affect quality of life for cancer survivors, and may worsen prognosis for several cancers. The current report highlights the importance of efforts to promote healthy weight and sufficient physical activity in reducing the cancer burden in the United States.

Abstract
OBJECTIVES The tumor suppressor in lung cancer 1 (TSLC1) has been identified as a putative tumor suppressor gene in non-small cell lung cancer. Although loss of TSLC1 has been observed in a number of human malignancies, the expression levels of TSLC1 gene in ovarian cancer and its clinical or prognostic significance have not been investigated. METHODS Protein expression levels of TSLC1 was explored by semiquantitative immunohistochemical staining on archival formalin-fixed, paraffin-embedded pathological specimen consisting of 30 normal ovaries, 30 ovarian cystadenomas, 40 borderline ovarian tumors, and 160 invasive ovarian carcinomas. The TSLC1 immunohistochemical staining results were then correlated with various clinicopathologic parameters and patient prognosis using various statistical models. RESULTS Significantly decreased, or complete loss of, protein expression of the TSLC1 gene was observed in 59% ovarian carcinomas, 45% borderline tumors, and 7% cystadenomas, but in none of the normal ovaries (0%). In ovarian carcinomas, decreased TSLC1 expression was significantly correlated with lymph node metastasis (pN, P = 0.001), distant metastasis (pM, P = 0.028), and more advanced International Federation of Gynecology and Obstetrics stages (P = 0.008). By univariate survival analysis on the ovarian carcinoma cohorts, decreased TSLC1 protein expression was significantly associated with shortened patient survival (mean: 26.9 months in tumors with complete loss of TSLC1 vs 63.1 months in tumors with significantly decreased TSLC1 vs 94.3 months in tumors with normal levels of TSLC1; P < 0.001). By multivariate analysis, TSLC1 protein expression remained as a significant and independent prognostic factor for the prediction of patient survival (P = 0.003). CONCLUSIONS Decreased protein expression of the TSLC1 gene might be important in conferring a more aggressive behavior in ovarian carcinoma. Thus, TSLC1 may be used as an independent prognostic molecular marker for patients with ovarian carcinoma.

Abstract
Prior research has demonstrated that specific isoflavones derived from soy may exhibit antitumor effects against many cancers, including oral cancer. Most of this prior research involved isolation and testing of individual soy components, such as genistein, daidzein, and glycitein, which exhibit cytotoxicity against cancerous cells but may also have residual cytotoxic effects on normal cells. Few studies have evaluated whole soy extract, containing a combination of these isoflavones, and other bioreactive compounds, which may function synergistically and more effectively against oral cancers. This study compared the antiproliferative effects of whole soy protein extract (SPE) on CAL 27 and SCC25 oral cancer cell lines in vitro. Administration of SPE significantly inhibited oral cancer growth and exerted these effects at lower concentrations compared with another class of flavonoids (proanthocyanidins) that were previously tested on these cell lines. This SPE-induced growth inhibition correlated with down-regulated mRNA expression in the oral cancer cell-cycle promoter ornithine decarboxylase (ODC), as well as upregulation of caspase-2 and caspase-8, initiators and effectors of apoptosis. These results suggest that SPE may represent a potential chemopreventive or chemotherapeutic option for oral cancer. Moreover, SPE may be more effective than other flavonoids currently used and may be effective at lower concentrations that approximate physiologic serum levels (0-2 μmol/l). This study may help to explain why diets rich in fruits, vegetables, and soy protein are associated with protection against development and progression of oral cancers, although further study is needed to develop specific public health recommendations for oral cancer treatment and prevention.

Abstract
BACKGROUND & AIMS There are no data regarding basal folate levels in patients without colorectal adenoma. This study aimed to determine the minimum serum folate concentration that associates with reduced risk of colorectal adenoma. METHODS 1510 consecutive patients underwent total colonoscopy for suspected colorectal lesions after barium enema examination. Prior to colonoscopy, history of alcohol consumption was noted and blood serum analyzed for folate and vitamin B12 levels. Polypoid lesions were evaluated histologically. We excluded patients with anemia, history of colonoscopy, overconsumption of alcohol, or malignancies. In all, 458/1510 patients (male/female; 258/200, 40-75 years) were determined eligible. Variables were compared between patients with adenoma and those without adenoma. RESULTS Serum folate concentration was the variable with the most significant statistical variation between males with adenoma (8.0 ng/ml) and males without adenoma (9.2) (p = 0.001). Serum folate concentrations in females with adenoma did not differ significantly from those in females without adenoma (10.7 versus 10.9). When subjects were stratified into groups according to serum folate, we found no significant difference in the prevalence of adenoma in patients with folate levels greater than 8.0 ng/ml. CONCLUSION Patients with serum folate concentrations above 8.0 ng/ml had the lowest risk of developing colorectal adenoma.

Abstract
Background The American Cancer Society, the Centers for Disease Control and Prevention (CDC), the National Cancer Institute, and the North American Association of Central Cancer Registries (NAACCR) collaborate annually to provide updated information on cancer occurrence and trends in the United States. This year’s report highlights brain and other nervous system (ONS) tumors, including nonmalignant brain tumors, which became reportable on a national level in 2004. Methods Cancer incidence data were obtained from the National Cancer Institute, CDC, and NAACCR, and information on deaths was obtained from the CDC’s National Center for Health Statistics. The annual percentage changes in age-standardized incidence and death rates (2000 US population standard) for all cancers combined and for the top 15 cancers for men and for women were estimated by joinpoint analysis of long-term (1992–2007 for incidence; 1975–2007 for mortality) trends and short-term fixed interval (1998–2007) trends. Analyses of malignant neuroepithelial brain and ONS tumors were based on data from 1980–2007; data on nonmalignant tumors were available for 2004–2007. All statistical tests were two-sided. Results Overall cancer incidence rates decreased by approximately 1% per year; the decrease was statistically significant (P < .05) in women, but not in men, because of a recent increase in prostate cancer incidence. The death rates continued to decrease for both sexes. Childhood cancer incidence rates continued to increase, whereas death rates continued to decrease. Lung cancer death rates decreased in women for the first time during 2003–2007, more than a decade after decreasing in men. During 2004–2007, more than 213 500 primary brain and ONS tumors were diagnosed, and 35.8% were malignant. From 1987–2007, the incidence of neuroepithelial malignant brain and ONS tumors decreased by 0.4% per year in men and women combined. Conclusions The decrease in cancer incidence and mortality reflects progress in cancer prevention, early detection, and treatment. However, major challenges remain, including increasing incidence rates and continued low survival for some cancers. Malignant and nonmalignant brain tumors demonstrate differing patterns of occurrence by sex, age, and race, and exhibit considerable biologic diversity. Inclusion of nonmalignant brain tumors in cancer registries provides a fuller assessment of disease burden and medical resource needs associated with these unique tumors.

Abstract
Aside from primary prevention, early detection remains the most effective way to decrease mortality associated with the majority of solid cancers. Previous cancer screening models are largely based on classification of at-risk populations into three conceptually defined groups (normal, cancer without symptoms, and cancer with symptoms). Unfortunately, this approach has achieved limited successes in reducing cancer mortality. With advances in molecular biology and genomic technologies, many candidate somatic genetic and epigenetic “biomarkers” have been identified as potential predictors of cancer risk. However, none have yet been validated as robust predictors of progression to cancer or shown to reduce cancer mortality. In this Perspective, we first define the necessary and sufficient conditions for precise prediction of future cancer development and early cancer detection within a simple physical model framework. We then evaluate cancer risk prediction and early detection from a dynamic clonal evolution point of view, examining the implications of dynamic clonal evolution of biomarkers and the application of clonal evolution for cancer risk management in clinical practice. Finally, we propose a framework to guide future collaborative research between mathematical modelers and biomarker researchers to design studies to investigate and model dynamic clonal evolution. This approach will allow optimization of available resources for cancer control and intervention timing based on molecular biomarkers in predicting cancer among various risk subsets that dynamically evolve over time.

Abstract
The potential for Comprehensive Cancer Control (CCC) across the nation has been realized in the last decade with 69 Coalitions developing and implementing CCC plans. Many partners at all levels--national, state, jurisdictional, tribal and communities--have contributed to this success. This article details the contribution of these partners across these various levels, with a selection of the many activities contributing to this success. Consequently the cancer burden, although still of major importance, continues to be addressed in significant ways. Although there are future challenges, CCC coalitions continue to play an important role in addressing the cancer burden.

Abstract
Sarcopenia, the age-related loss of skeletal muscle mass, is a significant public health concern that continues to grow in relevance as the population ages. Certain conditions have the strong potential to coincide with sarcopenia to accelerate the progression of muscle atrophy in older adults. Among these conditions are co-morbid diseases common to older individuals such as cancer, kidney disease, diabetes, and peripheral artery disease. Furthermore, behaviors such as poor nutrition and physical inactivity are well-known to contribute to sarcopenia development. However, we argue that these behaviors are not inherent to the development of sarcopenia but rather accelerate its progression. In the present review, we discuss how these factors affect systemic and cellular mechanisms that contribute to skeletal muscle atrophy. In addition, we describe gaps in the literature concerning the role of these factors in accelerating sarcopenia progression. Elucidating biochemical pathways related to accelerated muscle atrophy may allow for improved discovery of therapeutic treatments related to sarcopenia.

Abstract
Estrogen replacement therapy in women has demonstrated a protective effect in the development of colonic carcinomas. Gender-related differences in the development of colonic carcinomas have also been reported. Estrogen receptor beta (ERβ) is expressed in colon carcinomas and has demonstrated prognostic value in colon cancer patients. This study investigated an ERβ 3’ non-coding polymorphism associated with transcriptional activity to determine clinical outcome in patients with metastatic colon cancer. Genomic DNA from 318 metastatic colon cancer patients, 177 males and 141 females, were collected from 1992 to 2003. These patients were analyzed for CA repeat polymorphism of the ERβ gene. Gender-related survival differences were associated with an ERβ (CA)n repeat polymorphism (P for interaction=0.003, the likelihood ratio test). Female patients with any short <22 (CA)n repeat alleles had shorter overall survival compared to female patients that had both long ≥22 (CA)n repeat alleles. In the male patients the opposite overall survival difference was found. This study supports the role of an ERβ (CA)n repeat polymorphism as a prognostic marker in metastatic colon cancer; however, this prognostic factor had opposite implications based on gender.
