Quality of life and its predictors among patients with metastatic cancer in Bangladesh: the APPROACH survey.

BACKGROUND: This study aimed to assess the health-related quality of life (HRQOL) (physical, functional, emotional, social, spiritual) and psychological (anxiety and depression) well-being and their associations with patient characteristics among patients with metastatic cancer in Bangladesh. METHODS: A convenience sample of 386 Bangladeshi patients with stage IV solid cancers was recruited from a palliative care outpatient department and an inpatient palliative center. Dependent variables included the physical, functional, emotional, social, and overall scores of the Functional Assessment of Cancer Therapy-General (FACT-G) scale, the Functional Assessment of Chronic Illness Therapy-Spiritual Well-being (FACIT-SP) scale, the anxiety, depression, and overall scores of the Hospital Anxiety and Depression (HADS) scale. Linear regressions examined the association between dependent variables and patient characteristics. RESULTS: A substantial proportion of Bangladeshi patients reported anxiety (59% of outpatients and 55% of inpatients) and depression (60% of outpatients and 73% of inpatients) symptoms. Generally, greater financial difficulty and symptom burden scores were associated with worse health outcomes. Older patients reported poorer functional and spiritual well-being but better anxiety scores. Females reported worse anxiety and depressive symptoms and physical well-being but better spiritual outcomes. CONCLUSIONS: Additional efforts must be directed at improving the HRQOL of patients with metastatic cancer in Bangladesh. Furthermore, assistance should be made more accessible to vulnerable groups, including women, the elderly, and those with financial difficulty.

Perceived stigma and its correlates among Asian patients with advanced cancer: A multi-country APPROACH study.

OBJECTIVES: Perceived cancer-related stigma can affect mental health and potentially treatment choices for patients with cancer. Nevertheless, perceived stigma is not very well understood in Asia. This study investigated across six developing Asian countries: (1) the prevalence of perceived stigma among advanced cancer patients, (2) its risk factors, and (3) its association with patient treatment preferences. METHODS: This cross-sectional study recruited patients receiving oncology care across major hospitals in Bangladesh, China, India, Philippines, Sri Lanka and Vietnam. Participants (N = 1358) were adults diagnosed with stage IV metastatic solid cancer who completed self-reported surveys. Multi-variable logistic regression and ordered logit models examined the associations with perceived stigma and variables of interest. RESULTS: Across the countries, 35%, 95% CI [32%, 38%] of patients reported experiencing at least one facet of cancer-related stigma often or always, while 60% [57%, 63%] reported it occurring occasionally. Top-endorsed facets of perceived stigma across the Asian countries suggest a distinct pattern. Having knowingly engaged in health-risk behaviours (OR = 2.03-2.24, 95% CI [1.14-1.19, 3.43-4.41]), unemployment (2.64 [1.67, 4.19]) and body image change (1.57 [1.00, 2.45]) were associated with higher odds of perceived stigma, while time mitigated perceived stigma (0.49-0.65 [0.30-0.45, 0.76-0.92]). Perceived stigma was associated with lower odds of preference for life-extending treatments, although the associations did not hold up in the adjusted model. CONCLUSIONS: Perceived stigma is unique among Asian advanced cancer patients. Stigma is important to assess and address, taking into consideration the various sociodemographic, clinical and psychological factors of cancer patients.

Symptom Prevalence in Patients with Advanced, Incurable Illness in Bangladesh.

CONTEXT: There is a significant need for palliative care for patients living in low- and middle-income countries. The presence and intensity of physical symptoms is a major factor influencing the suffering of patients at the end of life. OBJECTIVES: The primary aim of this study was to determine the prevalence and characteristics of common physical symptoms experienced by patients with advanced, incurable illness in a developing country. METHOD: This study used semi-structured interviews in patients with advanced cancer or HIV/AIDS in Bangladesh. RESULTS: Pain was the most common symptom (70.6%) and was frequently reported to be severe (62.6%). Very few patients received strong opioids to treat their pain (13.7%). Other frequent symptoms included loss of appetite (23.5%) and fever (19.9%). The average number of physical symptoms reported was 3 (range: 0-23). The majority of patients rated their most recent symptom (excluding pain) as severe (64.3%), with 35.8% continuing to have severe symptom intensity despite treatment. CONCLUSIONS: This study reveals the significant burden of symptoms, and the associated suffering for patients living with incurable illness, in a developing country. Very few patients received strong opioids, despite frequently having severe pain. Frequently, the treatments that patients received did not alleviate their symptoms. Palliative care is vital for the relief of suffering for patients with advanced and incurable diseases, especially in low- and middle-income countries where access to curative treatments may be limited and patients often present to medical personnel when their illness is in an advanced stage or incurable.

A Massive Right Atrial Mass in Chronic Myelogenous Leukaemia: A Case Report and Literature Review.

Right atrial masses are rare and diagnosis can be difficult unless histopathological specimens are obtained. In addition, the clinical course is not well documented, thereby making diagnosis and management challenging. The mass can be associated with haemodynamic instability with the potential to cause obstructive shock and embolism. We present the case of a young woman with untreated chronic myelogenous leukaemia with a massive haemodynamically significant right atrial mass. The usefulness of multimodality imaging and a multidisciplinary approach for diagnosing and treating this condition is highlighted. LEARNING POINTS: Right atrial mass is rare and can lead to pulmonary embolism and haemodynamic instability.As chronic myelogenous leukaemia is associated with an increased risk of thromboembolism, thrombus should be considered in the differential diagnosis of intracardiac masses.Multimodality imaging is indicated to guide diagnosis and appropriate management; in case of diagnostic uncertainty, histopathology may be needed to obtain a definitive diagnosis.

Awareness and Utilization of Palliative Care Among Advanced Cancer Patients in Asia.

CONTEXT: To date, little is known about palliative care (PC) awareness and utilization in low- and middle-income countries (LMICs) in Asia. OBJECTIVES: This study aimed to investigate PC awareness and its predictors, utilization of PC services, and perceived utilization barriers among advanced cancer patients from select hospitals in Asian LMICs. METHODS: This cross-sectional study analyzed data of 759 advanced cancer patients at major hospitals of four LMICs in Asia (i.e., Bangladesh, Philippines, Sri Lanka, and Vietnam). The predictors of PC awareness were investigated using multivariable logistic regression. RESULTS: Overall PC awareness was 30.8% (n = 234). Patients with higher education (OR = 1.0; CI = 1.0,1.1), from upper-middle or high-income households (compared to low-income) (OR = 2.0; CI = 1.2,3.3), awareness of disease severity (OR = 1.5; CI = 1.0,2.2), and higher pain severity (OR = 1.1; CI = 1.0,1.2) had higher odds of PC awareness. Compared to patients who perceived themselves as being very informed about disease trajectory, those who were unsure (OR = 0.5; CI = 0.3,0.8) or uninformed (OR = 0.5; CI = 0.3,0.9) had lower odds of PC awareness. The PC utilization rate was 35.0% (n = 82) among those with PC awareness, and 47.8% (n = 66) among patients recommended PC by a healthcare professional (n = 138). The most cited PC utilization barriers were currently receiving anti-cancer treatment (n = 43; 33.9%), and having insufficient information about PC (n = 41; 32.3%). CONCLUSION: The low awareness of PC services in these major hospitals in Asian LMICs highlights that more effort may be required to promote the awareness of PC in this region. The efforts should especially focus on those from disadvantaged groups to reduce the gap in PC awareness.

Diuretic Resistance in Heart Failure.

Decompensated heart failure accounts for approximately 1 million hospitalizations in the United States annually, and this number is expected to increase significantly in the near future. Diuretics provide the initial management in most patients with fluid overload. However, the development of diuretic resistance remains a significant challenge in the treatment of heart failure. Due to the lack of a standard definition, the prevalence of this phenomenon remains difficult to determine, with some estimates suggesting that 25-30% of patients with heart failure have diuretic resistance. Certain characteristics, including low systolic blood pressures, renal impairment, and atherosclerotic disease, help predict the development of diuretic resistance. The underlying pathophysiology is likely multifactorial, with pharmacokinetic alterations, hormonal dysregulation, and the cardiorenal syndrome having significant roles. The therapeutic approach to this common problem typically involves increases in the diuretic dose and/or frequency, sequential nephron blockade, and mechanical fluid movement removal with ultrafiltration or peritoneal dialysis. Paracentesis is potentially useful in patients with intra-abdominal hypertension.

High anxiety and depression scores and mental health service use among South Asian advanced cancer patients: A multi-country study.

CONTEXT: Addressing symptoms of anxiety and depression is important in cancer palliative care. However, little information exists on the prevalence of anxiety and depression and mental health service use among advanced cancer patients in South Asia. OBJECTIVES: To examine among South Asian advanced cancer patients, the 1) prevalence of high anxiety and depression scores, 2) factors associated with high anxiety and depression scores, and 3) mental health service use. METHODS: This cross-sectional, multi-site study recruited patients receiving oncology care across six major public hospitals in India, Bangladesh and Sri Lanka. Participants were adults, diagnosed with stage IV metastatic solid cancer and aware they had cancer. Participants' high anxiety and depression scores (using clinically-relevant Hospital Anxiety and Depression Scale threshold of >10), sociodemographic characteristics, patient-perceived cancer stigma and mental health service use were assessed. RESULTS: In the overall sample (N = 1140), 54% met threshold for high anxiety and/or depression scores: 32% reported high anxiety scores and 47% reported high depression scores. Symptom burden (OR's [95% CI's] = 1.09-1.13 [1.05-1.09, 1.12-1.17]) and perceived stigma (1.11-1.16 [1.06-1.11, 1.16-1.22]) were statistically significantly associated with high anxiety and depression scores. Of the patients with high anxiety and/or depression scores (n = 617), 97% had not received mental health services, and 38% of them indicated they were open to a referral. CONCLUSION: High, clinically-relevant anxiety and depression scores are common among South Asian advanced cancer patients. Efforts should be made to alleviate psychological morbidity, including providing greater access to supportive/palliative medicine teams or mental health services.

Patient-Reported Roles in Decision-Making Among Asian Patients With Advanced Cancer: A Multicountry Study.

Purpose. We investigated 1) perceived roles in decision-making among advanced cancer patients in 5 Asian countries 2) associations of patient characteristics with these roles, and 3) the association of perceived roles with quality of life and perceived quality of care. Methods. We surveyed 1585 patients with stage IV solid cancer. Multinomial logistic regressions were used to analyze associations of patient characteristics with decision-making roles. Multivariate regressions were used to analyze associations of decision-making roles with quality of life and care. Results. The most common perceived-role was no patient involvement. Most patients (73%) reported roles consistent with their preferences. Being male, nonminority, higher educated, aware of advanced cancer diagnosis, and knowledge of cancer diagnosis for ≥1 year were associated with higher levels of patient involvement in decision-making. Compared to no patient involvement, joint decision-making (together with physicians/family) was associated with higher social (ß = 2.49, P < 0.01) and spiritual (ß = 2.64, P < 0.01) well-being, and better quality of physician communication (ß = 9.73, P < 0.01) and care coordination (ß = 13.96, P < 0.01) while making decisions alone was associated with lower emotional (ß = -1.43, P < 0.01), social (ß = -2.39, P < 0.01), and spiritual (ß = -2.98, P < 0.01) well-being. Conclusions. Findings suggest that a substantial number of advanced cancer patients were not (and preferred not to be) involved in decision-making. Despite this finding, joint decision-making together with physicians/family was associated with better quality of life and care. Implications. Physicians should explain the benefits of shared decision making to patients and encourage participation in decision-making, while ensuring that patients feel supported and do not find decision-making overwhelming.

Correlation between MRCP and ERCP findings at a tertiary care hospital.

BACKGROUND: It is common clinical practice to obtain Magnetic Resonance Cholangiopancreatography (MRCP) prior to Endoscopic Retrograde Cholangiopancreatography (ERCP) to evaluate the biliary system. With recent improvements of MRCP, it is important to correlate the findings of these two studies. AIM: To examine the correlation between MRCP and ERCP findings in patients at a tertiary care hospital. METHODS: A total of 165 patients were identified who underwent MRCP prior to ERCP at West Virginia University between July 1, 2004 and June 30, 2006 (98 females and 67 males). Patients' demographic information and their laboratory values and diagnostic study outcomes prior to procedure were collected, entered into MS Access, and analyzed using SAS 10.0. Sensitivity, specificity, positive predictive value and negative predictive value were calculated. Two-tailed p-values of <= 0.05 were considered statistically significant. RESULTS: Baseline demographic characteristics were comparable between male and female patients. Hepatobiliary and pancreatic duct results were grouped together. MRCP was 74.6% sensitive and 83.5% specific for choledocholithiasis, 85.4% sensitive and 87.4% specific for strictures, 85.9% sensitive and 91.2% specific for obstruction, 92.4% sensitive and 93.5% specific for ductal dilatation, and 90.8% sensitive and 92.6% specific for detection of periductal masses. MRCP appeared to have more false negative results for choledocholithiasis and strictures and more false positive results for ductal dilatation and periductal mass detection compared with ERCP. CONCLUSIONS: In patients with presentations suggestive of hepatobiliary and pancreatic disease, despite recent improvements in MRCP technique, the sensitivity and specificity of MRCP is still not close enough to that of ERCP for detection of choledocholithiasis, hepatobiliary and pancreatic ductal dilatation, periductal masses, or obstruction to be used as a substitute. Thus, ERCP remains the gold standard for visualization of the hepatobiliary and pancreatic tree.

Cardiogenic Pulmonary Edema.

The initial events in cardiogenic pulmonary edema involve hemodynamic pulmonary congestion with high capillary pressures. This causes increased fluid transfer out of capillaries into the interstitium and alveolar spaces. High capillary pressures can also cause barrier disruption which increases permeability and fluid transfer into the interstitium and alveoli. Fluid in alveoli alters surfactant function and increases surface tension. This can lead to more edema formation and to atelectasis with impaired gas exchange. Patients with barrier disruption have increased levels of surfactant protein B in the circulation, and these levels often remain high after the initial clinical improvement. Routine clinical assessment may not identify patients with increased extravascular fluid in the lungs; pulmonary ultrasound can easily detect pulmonary edema in patients with acute decompensation and in patients at risk for decompensation. Studies using serial pulmonary ultrasound could help characterize patients with cardiogenic pulmonary edema and help identify subgroups who need alternative management. The conventional management of cardiogenic pulmonary edema usually involves diuresis, afterload reduction and in some cases noninvasive ventilation to reduce the work of breathing and improve oxygenation. Patients with persistent symptoms, abnormal chest x-rays and diuretic resistance might benefit from alternative approaches to management. These could include beta agonists and pentoxifylline which warrant more study in patients with cardiogenic pulmonary edema.

Lung morphology and surfactant function in cardiogenic pulmonary edema: a narrative review.

The conventional analysis of acute cardiogenic pulmonary edema involves the development of high pulmonary capillary pressures resulting in hydrostatic gradients for fluid flux out of capillaries into the interstitial space and alveolar spaces. However, some patients respond poorly to diuretic management. The PubMed database was searched to identify experimental studies on pulmonary edema in animals, experimental studies on surfactant function, including patients with pulmonary edema, and clinical studies reporting barrier dysfunction and/or injury in patients with acute pulmonary edema. Studies with animal models demonstrate that high capillary pressures can cause barrier disruption in alveolar capillary units which increases permeability and the transfer of fluid and protein into lung parenchyma. Fluid in alveolar spaces alters surfactant function which increases fluid flux out of capillaries into the lung parenchyma secondary to larger transcapillary hydrostatic gradients. Patients with acute cardiogenic pulmonary edema have increased levels of surfactant protein B in their plasma which reflect barrier disruption and increased levels of tumor necrosis factor alpha which reflect acute tissue injury. Increased surfactant protein B plasma levels are associated with abnormal gas exchange in patients with chronic heart failure. Patients with exercise-induced left ventricular dysfunction have increased levels of surfactant protein B after short periods of exercise. Pathology studies in patients with chronic heart failure have found increased connective tissue in alveolar capillary units and increased numbers of type II alveolar cells, and these changes represent an adaptive response in these patients. Clinicians need to consider the possibility of barrier dysfunction and disruption in patients with both acute and chronic pulmonary edema and understand that diuresis may have a limited effect on symptoms in some patients.

Pure Squamous Cell Carcinoma of the Gallbladder Masquerading as a Hepatic Mass.

Gallbladder (GB) carcinomas are adenocarcinomas (AC) in the majority of cases. Adenosquamous carcinoma (ASC) and pure squamous cell carcinoma (SCC) of the gallbladder are rarely encountered and comprise 1-3% of gallbladder cancer cases.  Pure squamous cell carcinoma of the gallbladder is rarer with less than 1% of the incidence. Most of the published literature is based on case reports and case series. The survival rates of ASC and SCC of the gallbladder are significantly lower (mean of five months) compared to the AC of the gallbladder (mean survival of 11.4 months). Most of these lesions are advanced at presentation, rendering them unresectable and resulting in a poor prognosis. However, if the lesions are diagnosed at an early stage, they could potentially be resectable. We report one such rare case of pure SCC GB presenting as a hepatic mass. The patient subsequently underwent resection of the gallbladder and liver mass with complete recovery and is currently planned for chemotherapy and radiation treatment.

Mushroom Poisoning Mimicking Painless Progressive Jaundice: A Case Report with Review of the Literature.

Mushroom poisoning is common in the United States. The severity of mushroom poisoning may vary, depending on the geographic location, the amount of toxin delivered, and the genetic characteristics of the mushroom. Though they could have varied presentation, early identification with careful history could be helpful in triage. We present a case of a 69-year-old female of false morel mushroom poisoning leading to hepatotoxicity with painless jaundice and biochemical pancreatitis.

Trend analysis and survival of primary gallbladder cancer in the United States: a 1973-2009 population-based study.

Primary gallbladder cancer is an aggressive and uncommon cancer with poor outcomes. Our study examines epidemiology, trend, and survival of gallbladder cancer in the United States from 1973 to 2009. We utilized the Surveillance Epidemiology and End Results database (SEER). Frequency and rate analyses on demographics, stage, and survival were compared among non-Hispanic whites, Hispanics, African American, and Asian/Pacific Islanders. A total of 18,124 cases were reported in SEER from 1973 to 2009 comprising 1.4% of all reported gastrointestinal cancers. Gallbladder cancer was more common in females than males (71 vs. 29%, respectively). The age-adjusted incidence rate was 1.4 per 100,000, significantly higher in females than males (1.7 vs. 1.0). Trend analysis showed that the incidence rate has been decreasing over the last three decades for males. However, among females, the incidence rate had decreased from 1973 to mid-90s but has remained stable since then. Trend analysis for stage at diagnosis showed that the proportion of late-stage cases has been increasing significantly since 2001 after a decreasing pattern since 1973. Survival has improved considerably over time, and survival is better in females than males and in Asian/Pacific Islanders than other racial groups. The highest survival was in patients who received both surgery and radiation. Trend analysis revealed a recent increase of the incidence of late-stage gallbladder cancer. Highest survival was associated with receiving both surgery and radiation.

Pre-endoscopic erythromycin administration in upper gastrointestinal bleeding: an updated meta-analysis and systematic review.

BACKGROUND: In patients suffering from upper gastrointestinal bleeding (UGIB), adequate visualization is essential during endoscopy. Prior to endoscopy, erythromycin administration has been shown to enhance visualization in these patients; however, guidelines have not fully adopted this practice. Thus, we performed a comprehensive, up-to-date meta-analysis on the issue of erythromycin administration in this patient population. METHODS: After searching multiple databases (November 2015), randomized controlled trials on adult subjects comparing administration of erythromycin before endoscopy in UGIB patients to no erythromycin or placebo were included. Pooled estimates of adequacy of gastric mucosa visualized, need for second endoscopy, duration of procedure, length of hospital stay, units of blood transfused, and need for emergent surgery using odds ratio (OR) or mean difference (MD) were calculated. Heterogeneity and publication bias were assessed. RESULTS: Eight studies (n=598) were found to meet the inclusion criteria. Erythromycin administration showed statistically significant improvement in adequate gastric mucosa visualization (OR 4.14; 95% CI: 2.01-8.53, P<0.01) while reduced the need for a second-look endoscopy (OR 0.51; 95% CI: 0.34-0.77, P<0.01) and length of hospital stay (MD -1.75; 95% CI: -2.43 to -1.06, P<0.01). Duration of procedure (P=0.2), units of blood transfused (P=0.08), and need for emergent surgery (P=0.88) showed no significant differences. CONCLUSION: Pre-endoscopic erythromycin administration in UGIB patients significantly improves gastric mucosa visualization while reducing length of hospital stay and the need for second-look endoscopy.

Increased risk for colorectal cancer under age 50 in racial and ethnic minorities living in the United States.

Colorectal cancer (CRC) is the second most common cause of cancer death in USA. We analyzed CRC disparities in African Americans, Hispanics, Asians/Pacific Islanders, and American Indians/Alaska Natives compared to non-Hispanic Whites. Current guidelines recommend screening for CRC beginning at age 50. Using SEER (Surveillance, Epidemiology, and End Results) database 1973-2009 and North American Association of Central Cancer Registries (NAACCR) 1995-2009 dataset, we performed frequency and rate analysis on colorectal cancer demographics and incidence based on race/ethnicity. We also used the SEER database to analyze stage, grade, and survival based on race/ethnicity. Utilizing SEER database, the median age of CRC diagnosis is significantly less in Hispanics (66 years), Asians/Pacific Islanders (68 years), American Indians/Alaska Natives (64 years), and African Americans (64 years) compared to non-Hispanic whites (72 years). Twelve percent of Asians/Pacific Islanders, 15.4% Hispanics, 16.5% American Indians/Alaska Natives, and 11.9% African Americans with CRC are diagnosed at age <50 years compared to only 6.7% in non-Hispanic Whites (P < 0.0001). Minority groups have more advanced stages at diagnosis compared to non-Hispanic Whites. Trend analysis showed age-adjusted incidence rates of CRC diagnosed under the age of 50 years have significantly increased in all racial and ethnic groups but are stable in African Americans. These results were confirmed through analysis of NAACCR 1995-2009 dataset covering nearly the entire USA. A significantly higher proportion of minority groups in USA with CRC are diagnosed before age 50 compared to non-Hispanic Whites, documenting that these minority groups are at higher risk for early CRC. Further studies are needed to identify the causes and risk factors responsible for young onset CRC among minority groups and to develop intervention strategies including earlier CRC screening, among others.

Prophylactic tracheal intubation for upper GI bleeding: A meta-analysis.

AIM: To evaluate usefulness of prophylactically intubating upper gastrointestinal bleeding (UGIB) patients. METHODS: UGIB results in a significant number of hospital admissions annually with endoscopy being the key intervention. In these patients, risks are associated with the bleeding and the procedure, including pulmonary aspiration. However, very little literature is available assessing the use of prophylactic endotracheal intubation on aspiration in these patients. A comprehensive search was performed in May 2014 in Scopus, CINAHL, Cochrane databases, PubMed/Medline, Embase, and published abstracts from national gastroenterology meetings in the United States (2004-2014). Included studies examined UGIB patients and compared prophylactic intubation to no intubation before endoscopy. Meta-analysis was conducted using RevMan 5.2 by Mantel-Haenszel and DerSimonian and Laird models with results presented as odds ratio for aspiration, pneumonia (within 48 h), and mortality. Funnel plots were utilized for publication bias and I2 measure of inconsistency for heterogeneity assessments. RESULTS: Initial search identified 571 articles. Of these articles, 10 relevant peer-reviewed articles in English and two relevant abstracts were selected to review by two independent authors (Almashhrawi AA and Bechtold ML). Of these studies, eight were excluded: Five did not have a control arm, one was a letter the editor, one was a survey study, and one was focused on prevention of UGIB. Therefore, four studies (N = 367) were included. Of the UGIB patients prophylactically intubated before endoscopy, pneumonia (within 48 h) was identified in 20 of 134 (14.9%) patients as compared to 5 of 95 (5.3%) patients that were not intubated prophylactically (P = 0.02). Despite observed trends, no significant differences were found for mortality (P = 0.18) or aspiration (P = 0.11). CONCLUSION: Pneumonia within 48 h is more likely in UGIB patients who received prophylactic endotracheal intubation prior to endoscopy.

Gastric cancer in Africa: current management and outcomes.

Gastric cancer is the fourth most common cancer and second most common cause of cancer death worldwide. Globally, gastric cancer poses a significant public health burden - both economically and socially. In 2008, the economic burden from premature cancer deaths and disability was $895 billion and gastric cancer was the second highest cancer responsible for healthy life lost. With the expected increase in cancer deaths and non-communicable diseases, these costs are expected to rise and impact patient care. World Health Organization, estimates a 15% increase in non-communicable disease worldwide, with more than 20% increase occurring in Africa between 2010 and 2020. Mali, West Africa, is ranked 15(th) highest incidence of gastric cancer worldwide at a rate of 20.3/100000, yet very scarce published data evaluating etiology, prevention or management exist. It is understood that risk factors of gastric cancer are multifactorial and include infectious agents (Helicobacter pylori, Epstein-Barr virus), genetic, dietary, and environmental factors (alcohol, smoking). Interestingly, African patients with gastric cancer are younger, in their 3(rd)-4(th) decade, and present at a late stage of the disease. There is sparse data regarding gastric cancer in Africa due to lack of data collection and under-reporting, which impacts incidence and mortality rates. Currently, GLOBOCAN, an International Agency for Research on Cancer resource, is the most comprehensive available resource allowing comparison between nations. In resource limited settings, with already restricted healthcare funding, data is needed to establish programs in Africa that increase gastric cancer awareness, curtail the economic burden, and improve patient management and survival outcomes.

Characteristics of gastric cancer in Asia.

Gastric cancer (GC) is the fourth most common cancer in the world with more than 70% of cases occur in the developing world. More than 50% of cases occur in Eastern Asia. GC is the second leading cause of cancer death in both sexes worldwide. In Asia, GC is the third most common cancer after breast and lung and is the second most common cause of cancer death after lung cancer. Although the incidence and mortality rates are slowly declining in many countries of Asia, GC still remains a significant public health problem. The incidence and mortality varies according to the geographic area in Asia. These variations are closely related to the prevalence of GC risk factors; especially Helicobacter pylori (H. pylori) and its molecular virulent characteristics. The gradual and consistent improvements in socioeconomic conditions in Asia have lowered the H. pylori seroprevalence rates leading to a reduction in the GC incidence. However, GC remains a significant public health and an economic burden in Asia. There has been no recent systemic review of GC incidence, mortality, and H. pylori molecular epidemiology in Asia. The aim of this report is to review the GC incidence, mortality, and linkage to H. pylori in Asia.

Primary hepatocellular carcinoma and metabolic syndrome: An update.

Hepatocellular carcinoma (HCC) is the most common primary liver malignancy. The incidence of hepatocellular carcinoma has increased dramatically by 80% over the past two decades in the United States. Numerous basic science and clinical studies have documented a strong association between hepatocellular carcinoma and the metabolic syndrome. These studies have documented that, in most patients, non-alcoholic fatty liver disease is the hepatic manifestation of the metabolic syndrome, which may progress to hepatocellular carcinoma through the cirrhotic process. However, minority of patients with non-alcoholic fatty liver disease may progress to hepatocellular carcinoma without cirrhosis. This review summarizes the current literature of the link between hepatocellular carcinoma and metabolic syndrome with special emphasis on various components of the metabolic syndrome including risk of association with obesity, diabetes mellitus, hyperlipidemia, and hypertension. Current understanding of pathophysiology, clinical features, treatments, outcomes, and surveillance of hepatocellular carcinoma in the background of metabolic syndrome and non-alcoholic fatty liver disease is reviewed. With the current epidemic of metabolic syndrome, the number of patients with non-alcoholic fatty liver disease is increasing. Subsequently, it is expected that the incidence and prevalence of HCC will also increase. It is very important for the scientific community to shed more light on the pathogenesis of HCC with metabolic syndrome, both with and without cirrhosis. At the same time it is also important to quantify the risk of hepatocellular carcinoma associated with the metabolic syndrome in a prospective setting and develop surveillance recommendations for detection of hepatocellular carcinoma in patients with metabolic syndrome.
