Clinical characteristics and outcomes in young patients with myocardial infarction

Abstract Background Young people hold a stable or increasing percentage of patients with acute myocardial infarction in many countries. However, data on clinical characteristics and outcomes in young patients are lacking. Purpose To compare clinical characteristics and outcomes between patients aged ≤45 years and those aged >45 years with acute myocardial infarction. Methods A total of 24125 patients with acute myocardial infarction between January 2013 and September 2014 from China Acute Myocardial Infarction (CAMI) registry were included in this study. Clinical characteristics, in-hospital and 2-year outcomes were compared between patients aged ≤45 years (young) and those aged >45 years (older). Gender disparity in prognosis of myocardial infarction was analyzed among young patients. Results Of 24125 patients, 2042 (8.5%, 116 female) were aged ≤45 years. Compared with patients aged >45 years, young patients were more often male, current smokers, having medical history of hyperlipidemia and family history of premature coronary artery disease. Young patients were significantly more likely to have clear trigger factor, present with persistent chest pain and suffer ST-segment elevation myocardial infarction. Symptom onset to admission time was shorter in patients aged ≤45 years. For patients undergoing emergency coronary angiography, those aged ≤45 years were more likely to suffer left anterior descending coronary artery related myocardial infarction. Young patients were significantly more likely to receive percutaneous coronary intervention and other medications at discharge, including dual antiplatelet therapy, statins, angiotensin converting enzyme inhibitors or angiotensin II receptor blockers and β blockers. Compared with patients aged >45 years, young patients experienced significantly lower in-hospital and 2-year mortality and major adverse cardiac and cerebrovascular events (MACCE, a composite of death, reinfarction and stroke) rates (Table 1). Among young patients, women experienced higher in-hospital mortality and MACCE rates than men (Table 2). Women who survived at discharge experienced significantly higher 2-year mortality (1.4% vs 3.8%, Log-rank P=0.0412, Table 2). Conclusions Compared with the older patients, young patients were more likely to present with typical symptoms and receive guideline-recommended medications. Clinical outcomes of patients aged ≤45 years were significantly better than older patients. However, our results showed significant gender disparity in both short- and long-term outcomes of young patients. More efforts are needed to improve prognosis in young patients with acute myocardial infarction. Funding Acknowledgement Type of funding sources: Public grant(s) – National budget only.

The association between diabetes and mortality in young adults presenting with myocardial infarction

Abstract Background The incidence of diabetes mellitus and coronary artery disease continue to rise and collectively comprise two of the most prevalent and costly diseases worldwide. The goal of this study is to report the prognosis of young patients with diabetes presented with acute myocardial infarction (AMI). Methods This is a retrospective observational cohort study that included consecutive patients aged 18–45 years who underwent cardiac catheterization for AMI between 2006 and 2016 in an integrated healthcare system in Southern California. The prognosis of patients with diabetes were compared to those without diabetes. Results A total of 1,560 patients (average age 40.2±5.3 years, 25.6% female) presenting with AMI were included. Of these 272 (17.4%) had diabetes. Diabetics were older (41.1±4.4 vs 40.0±5.4 years), more likely to be female (32.4% vs 24.1%, p=0.006), Hispanic (51.5% vs 40.5%, p<0.001), have a higher body mass index (BMI) (33.6±7.1 vs 31.2±6.8kg/m2, p<0.001), have hypertension (HTN) (67.6% vs 23.8%, p<0.001), hyperlipidemia (HLD) (78.3% vs 24.1%, p<0.001), peripheral vascular disease (9.9% vs 1.9%, p<0.001), chronic kidney disease (CKD) (23.2% vs 2.7%, p<0.001), hypothyroidism (7% vs 4%, p=0.034), and prior strokes (4.4% vs 2.2%, p=0.034). On multivariate analysis accounting for other cardiovascular risk factors, the association remained significant (OR 1.82, 95% CI 1.04–3.19, p=0.036). At a median follow-up of 5.8 years (interquartile range 3.7–8.7 years), diabetes was independently associated with increased all-cause mortality (Hazard ratio [HR] 3.10, 95% CI 1.68–5.69, p<0.001) when adjusting for age, sex, race, BMI, HTN, HLD, CKD, hypothyroidism, prior stroke, and ACS etiology. In a propensity score matched cohort, diabetes remained significantly associated with all-cause mortality (HR 5.29, 95% CI 2.34–12.02, p<0.001). Conclusion Diabetes is an independent predictor of increased mortality in young adults <45 years old presenting with AMI. Funding Acknowledgement Type of funding sources: Private hospital(s).

Possibilities of predicting preclinical forms of cardiovascular diseases in young patients with type 1 diabetes mellitus using cardiac magnetic resonance imaging

Aim. To identify the indicators of cardiac magnetic resonance (CMR), which have diagnostic value in the individual assessment of the cardiovascular prognosis in young patients with type 1 diabetes mellitus (T1DM).Material and Methods. The study included a total of 60 patients (29 men and 31 women) aged 18 to 36 years with a history of T1DM from 5 to 16 years, who underwent contrast-enhanced CMR. Circular strain, strain relaxation index (SRI), peak early diastolic strain rate (SRe), epicardial fat thickness (EFT), ejection fraction (EF), stroke volume (SV), end-diastolic volume (EDV), end-systolic volume (ESV), and left ventricular mass (LVM) were assessed. Echocardiography, 24-h electrocardiography (ECG), treadmill test, and NT-proBNP blood test were performed to exclude heart pathology. Statistical data processing was used to identify the relationships of changes in CMR parameters of the left ventricle and epicardial adipose tissue with disease duration, carbohydrate metabolism compensation (HbA1c), total cholesterol, and low-density lipoprotein (LDL).Results. Using the nonparametric Mann – Whitney U-test, the study showed the presence of significant differences in the values of SV, EDV, end-diastolic volume index (EDVI), and LVM in the groups of 5–10and 11–16-year duration of disease, respectively. The assessment of Spearman’s rank correlation coefficients revealed negative correlations between the values of SV, ESV, ESV index (ESVI), EDV, and LVM and T1DM duration; between the index of circular strain and blood level of HbA1c; between the values of SV, EDVI, ESVI, EDV, ESV, and LVM and blood levels of total cholesterol and LDL; between SV, EDVI, ESVI, EDV, ESV, and LVM and mean EFT in the left ventricular projection.Conclusion. The CMR-based evaluation of strain parameters may become a key in personalized identification of young T1DM patients with a high risk of adverse cardiovascular events. The thickness and distribution of epicardial adipose tissue in young patients with T1DM may have predictive value for risk stratification of developing diseases associated with atherosclerosis and chronic heart failure, which will affect the primary prevention strategy in this population.

Агрессивное течение окклюзии ветви центральной вены сетчатки у молодых пациентов после COVID-19 (клинические случаи)

Retinal vein occlusions are believed to have a more favorable prognosis in young patients (<50 years old) due to spontaneous regression. However, 20% of patients have a poor outcome with severe neovascular complications. The causal relationship of occlusion in this age group is still unclear in most cases. There are reports of the development of a clinical picture of retinal vein occlusion in patients with COVID-19, the formation of which is most likely due to hypercoagulation syndrome. Purpose. To present a clinical case of post thrombotic retinopathy in a young patient after COVID-19. Material and methods. A clinical example of post thrombotic retinopathy in a young patient with retinal vein occlusion. Conclusion. Management of patients with retinal vein occlusion, especially at a young age, requires a comprehensive diagnostic approach with an assessment of systemic risk factors and mandatory assessment of the initial degree of retinal ischemia according to fluorescein angiography or Optical coherence tomography angiography. The clinical criteria for the increase in retinal ischemia are a decrease in central visual acuity, macular edema, ischemic area increase, and at the later stages - retinal neovascularization and / or of the anterior segment of the eye. COVID-19 did not affect significantly the change in the parameters of the coagulogram indices. However, its effect as an aggravating factor in a patient with a genetic predisposition to vascular and microvascular diseases cannot be excluded. Key words: OCTA-angiography, retinal neovascularization, post thrombotic retinopathy.

Acute Coronary Syndrome Below 50 Yrs.

Background: Coronary artery disease is a catastrophic diseased, despite the recent decline in mortality, with improving facilities, more distressing if occurs in young, clearly because an otherwise healthy adult may die or become disabled without caution, besides the tragic consequences for the family, friends, and the job might be unexpected. The study aims to focus on these physically active groups and to get an idea about how to prevent them. Method: In a prospective study 365 patients with an acute coronary syndrome, of them, 117 adults age less than 50 years and 248 patient were above 50 yrs, underwent coronary angiography . were assessed comparatively for the contribution of many risk factors with the clinical and angiographic variable. Result: about one-third of cases who present with the acute coronary syndrome were more young, male, and smoker, with a family history of ischemic heart disease, more likely to had a myocardial infarction, rather than angina, usually single-vessel disease, with low high-density lipoprotein. Conclusion: In our study, we found a strong association with smoking, family history and low HDL with early ischemic heart disease. Abstinence from smoking with diet and exercise might help to improve these major risks. Screening for CHD in the young population may help to improve prognosis in young patients by detecting subclinical disease.

Oral Cancer in Young vs Old Individuals: A Systematic Review

To compare various parameters associated with oral cancer in young and old patients and systematically compile the data on prognosis or outcome of oral cancer in young and old patients that include case series, matched-pair analyses, institutional series, and database reviews. Though oral cancer is considered a disease of old age, a recent clinical scenario witnesses its increasing incidence among young persons. When compared to old patients, young patients with oral cancer are exposed to the carcinogens for a very petite period of time suggesting underlying pathogenesis to be distinct from that in older individuals. Literature reports several studies about the occurrence of oral cancer in young patients; however, no unanimous opinion exists about its prognosis and treatment outcomes when compared to older patients. Keeping this in mind, we have extensively studied all the possible aspects (location, local and regional recurrence, nodal and distant metastasis, overall survival, etc.) from the English literature and systematically compiled the available data on prognosis or outcomes of oral cancer. The overall outcome of the case series shows poorer prognosis in young patients, matched-pair analyses, and institutional series suggesting no significant differences whereas the databases favored a better prognosis in young patients. The mean overall survival rate was found to be better for young patients in the database and institutional review whereas worse in the matched-pair analyses. The mean 5-year survival rate was found to be more in young individuals in matched-pair analyses, database reviews, and institutional series as compared to older oral cancer patients. Though data extracted from various study designs are heterogeneous, the present review gives a scoping view of the papers published on oral cancer in young vs old patients. More prospective studies are suggested with a larger sample size in the future. The present review will help to better understand the nature, course, and biologic behavior of oral cancer in young patients leading to the development of specific treatment strategies to manage the patients based on their age-groups.

Long-Term Prognosis in Young Patients with Acute Coronary Syndrome Treated with Percutaneous Coronary Intervention.

BackgroundAcute coronary syndrome (ACS) at a young age is uncommon. Limited data regarding the long-term follow-up and prognosis in this population are available. Our objectives were to evaluate the long-term clinical outcomes of patients presenting with ACS at a young age and to assess factors that predict long-term prognosis.MethodsA retrospective analysis of consecutive young patients (male below 40 and female below 50 years old) that were admitted with ACS and underwent percutaneous coronary intervention (PCI) between the years 1997 and 2009. Demographics, clinical characteristics, and clinical outcomes including major cardiovascular (CV) events and mortality were analyzed. Multivariable cox proportional hazard model was performed to identify predictors of long-term prognosis.ResultsOne-hundred sixty-five patients were included with a mean follow-up of 9.1±4.6 years. Most patients were men (88%), and mean age (years) was 36.8±4.2. During follow-up, 15 (9.1%) died, 98 (59.4%) patients had at least one major CV event, 22 (13.3%) patients had more than two CV events, and the mean number of recurrent CV events was 1.4±1.48 events per patient. In multivariate analysis, the strongest predictors of major CV events and/or mortality were coronary intervention without stent insertion (HR1.77; 95% CI 1.09–2.9), LAD artery involvement (HR 1.59; 95% CI 1.04–2.44) and hypertension (HR 1.6; 95% CI 1.0–2.6).ConclusionPatients with ACS in young age are at high risk for major CV and/or mortality in long-term follow-up with a high rate of recurrent CV events. Close follow-up and risk factor management for secondary prevention have a major role, particularly in this population.

Clinicopathological characteristics and prognosis of young patients with upper tract urethelial carcinoma

Objective: To investigate the clinicopathological characteristics and prognosis of the young patients with upper tract urothelial carcinoma (UTUC). Methods: The clinical data of 839 UTUC patients receiving radical nephroureterectomy at Peking University Third Hospital, Beijing, China from September 1999 to September 2019 were retrospectively analyzed. The patients were divided into the young (<55 years old, 107 cases) and elderly groups (≥55 years old, 732 cases). After the variables were balanced using propensity score matching, the patients were paired at a 1∶1 ratio. The clinicopathological characteristics and survival rates were compared between the two groups. Results: Compared with the elderly group, the young group had more males (P=0.047), a higher rate of smoking history (P=0.042), a higher rate of renal transplantation history (P<0.01), and fewer symptoms of hematuria (P=0.048). The 1-, 3-, and 5-year cancer specific survival (CSS) rates after surgery were 77.9%, 62.2%, 60.2% and 85.7%, 70.3%, 65.0% in the young and the elderly groups, respectively. The CSS and disease free survival (DFS) of young patients were shorter than those of elderly patients, but the difference was not significant either by subgroup analysis or propensity matching analysis (P>0.05). Young female patients had shorter CSS (P=0.034) and DFS (P=0.046) than elderly females. Perineural invasion (CSS, P=0.002; DFS, P<0.01) and extensive necrosis (CSS, P=0.041; DFS, P=0.001) were the independent risk factors of survival in young patients. Conclusions: Young UTUC patients are different from elderly ones in the frequencies of gender, smoking history, renal transplantation history, and first symptoms. Young female patients have a worse prognosis than elderly female ones. Perineural invasion and extensive necrosis could help clinicians to evaluate the prognosis of young UTUC patients.

Effects of clinicopathological factors on prognosis of young patients with resected breast cancer.

This study aims to analyze the relationship between clinicopathological characteristics and survival in young patients (≤35 years old) with resected breast cancer.A total of 173 cases were included in this study. The clinicopathological factors potentially associated with prognosis were evaluated. Furthermore, we categorized patients into different groups to evaluate the prognosis according to hormone receptor status or important risk factors.Younger age (≤30 years) was an independent predictor for poor disease-free survival (DFS) and overall survival (OS). Besides, PR negative status, tumor grade, and advanced lymph nodes postsurgery were independent prognostic factors of DFS, while PR negative status and advanced lymph nodes postsurgery were independent prognostic factors of OS. For hormone receptor-positive patients, people with ER+ or PR+ and HER2−/+ showed poorer prognosis than the other 2 levels. Risk factor grouping based on the ER, PR, HER2, Ki-67 status, tumor grade, and lymph nodes postsurgery showed that patients in highest score group received the poorest prognosis. Grading system based on the hormone status or the risk factor grouping may offer a useful approach to assess which subgroups of young breast cancer present poorer prognosis.

Prognosis of young patients with monoclonal gammopathy of undetermined significance (MGUS)

Monoclonal gammopathy of undetermined significance (MGUS) is rare in young patients (age <40 years at diagnosis), with a prevalence of <0.3%, representing ~2% of all patients with MGUS. We hypothesized that MGUS detected in young patients may be associated with a higher risk of progression. We examined 249 patients with MGUS < 40 years old. Among these, 135 patients had immune-related conditions, including infections, autoimmune and inflammatory disorders at the time of diagnosis of MGUS. The risk of progression to multiple myeloma or a related disorder at 5 years and 10 years was 6.0% and 13.8%, respectively. The size of M protein was a significant risk factor for progression (HR 4.2, 95% CI 2.2–7.9). There was a trend that the risk of progression was higher in patients without immune-related conditions (HR 2.36, 95% CI 0.85–6.52, p = 0.088). The M protein resolved in 36 (14%) patients, with a greater likelihood of resolution in patients with immune-related conditions (RR 1.9, 95% CI 1.02–3.6). Young patients with MGUS have a similar risk of progression as older patients, 1.4% per year. Over 50% are diagnosed in the setting of immune-related disorders. Patients with immune-related disorders may have a lower risk of progression.

Progesterone Receptor Is a Haploinsufficient Tumor-Suppressor Gene in Cervical Cancer

Tumor-suppressor genes (TSG) are often deleted or transcriptionally suppressed in cancer. PGR codes for progesterone receptor (PR), a transcription factor whose function depends on its ligand. Although PR expression is often undetectable in cervical cancer, its relevance to the endocrine-related etiology of this prevalent gynecological disease remains unclear. In this study, we show that the deletion of one Pgr allele in cervical epithelium promoted spontaneous cervical cancer in human papilloma viral oncogene-expressing transgenic mice as efficiently as the ablation of both Pgr alleles. We also show that tumors arising in the transgenic mice with one or both Pgr alleles did not express PR or expressed at the reduced levels compared with the normal epithelium. PR status correlated with estrogen receptor α (ERα) status in the mouse model and the Cancer Genome Atlas (TCGA) dataset. TCGA data analyses revealed that PGR expression significantly decreased in cervical cancer and that the biallelic deletion of PGR was rare. Furthermore, low PGR expression was associated with poor prognosis in young patients with cervical cancer. These discoveries point to PGR as a haploinsufficient TSG in the uterine cervix. They also raise the possibility that the restoration of PGR expression may improve the survival rate. IMPLICATIONS: The decreased expression of PR may increase the risk of cervical cancer in human papillomavirus-infected women.

Analysis of Clinicopathological Characteristics and Prognosis of Young Patients with Hepatocellular Carcinoma after Hepatectomy.

Background and Aims: This study was designed to analyze the effects of age and clinicopathological characteristics on prognosis of Chinese patients with hepatocellular carcinoma (HCC).Methods: The clinical data of 2032 HCC patients who were first diagnosed with HCC and underwent curative hepatectomy in our hospital between January 2006 and January 2011 were retrospectively analyzed.Results: Younger HCC patients (age <40 years, n=465) had a significantly higher hepatitis B infection rate, larger tumors, higher alpha-fetoprotein levels, higher preoperative liver function, and more frequent vascular invasions than older patients. Most younger patients were suitable for anatomical hepatectomy, and their tumors were found to be at a highly advanced stage. The recurrence-free survival and overall survival rates of younger HCC patients were significantly worse than those of older patients but this difference disappeared after propensity score matching. Multivariate analysis of pre-matched samples showed that age ≤40 years was one of the independent risk factors associated with poor overall survival.Conclusions: Younger patients showed different clinicopathological characteristics than older patients, such as higher rates of hepatitis B infection and advanced tumors. The recurrence-free survival and overall survival rates of younger HCC patients after hepatectomy may be similar to those of older patients.

The outcomes and quality of life of young patients undergoing adjuvant radiotherapy versus non-radiotherapy following surgery treating early FIGO stage cervical squamous cell cancer in southwestern China

Background: The incidence of cervical cancer in young women is rising, and squamous cell carcinoma makes up a great percentage of the histological types. The presence of aggressive pathologic risk factors following patients’ primary surgery may warrant the use of adjuvant radiotherapy. It is important to weigh up the risks and benefits of using adjuvant radiotherapy for each young patient so as to maximize their prognosis while minimizing the treatment-related morbidity. Methods: A retrospective study was performed. It consisted of 97 patients under 35 years old who were diagnosed with cervical squamous cell carcinoma and underwent treatment at West China Second University Hospital between December 2009 and January 2014. Five-year follow-up, prognostic risks, long-term radiation toxicity, female sexual function, and quality of life were investigated. Results: Adjuvant radiotherapy did improve the prognosis of young patients with lymph node metastases. However, there were few significant differences in progress-free survival and overall survival for the young patients without lymph node metastases following adjuvant radiotherapy. Besides, young patients who took radiotherapy exhibited greater intestinal dysfunction, more severe lower extremities edema, greater sexual dysfunction, and worse long-term quality of life. Conclusion: Young patients with early-stage cervical squamous cell carcinoma without lymph node metastases who have undergone the primary surgery should be counseled in detail before the decision to use adjuvant radiotherapy can be made. The counseling should emphasize not only the benefit that local recurrence rates can be reduced, but also the risks that treatment-related side effects could increase and lower QoL could occur.

Molecular profiling and clinical characteristic of malignant melanoma in younger patients.

e22087 Background: Combination of clinical and molecular data has not yet been well established in adolescent and younger adult patients with melanoma Methods: We performed a retrospective analysis of the molecular profiles and clinical outcome of patients diagnosed at the age younger than 40 treated at UCLA during 2010 to 2019. Patient’s molecular profile, characteristics, and treatment outcome were described using descriptive statistic. Kaplan-Meier curve was used for disease-free survival (DFS) and overall survival (OS). Results: 150 patients with a median age of 29 year (12-39) were analyzed. 101 (67.3%) patients had cutaneous melanoma, 49 (32.7%) had localized uveal melanoma. Of those 101, 23.8% had pre-existing benign or congenital nevus. 70/101 (69.3%) was stage I-II, 26/101 (25.7%) stage III and 5/101 (4.9%) stage IV. Of those 37 patients with molecularly characterized tissue, 23 (62%) had BRAF mutation including 17 V600E, 4 V600 unknown codon, 2 G469A, 2 NRAS and 1 NF-1 mutation. 11/37 were BRAF negative. 79.6% of patients who were not tested were stage I. For patients with stage III, 16/26 (61%) received adjuvant immunotherapy, none of adjuvant targeted therapy. At 35.1 months follow-up time, 27/96 (28%) localized cutaneous melanoma experienced relapse. 1-year DFS was 73% in adjuvant vs. 90% in no adjuvant immunotherapy group. Among 49 uveal melanoma patients, the median age was 27 years old. 23/49 (49%) had a T1 tumor, 18/49 (36.7%) T2, 6/49(12.2%) T3, 1/49(2%) T4. At 45 months follow-up time, three (6.1%) patients developed metastasis. 5-year DFS and OS was 90% and 100%, respectively. 45 patients had tissue for gene expression profiling and/or FISH testing. 15/45 (33%) had class IA, 13/45 (28%) had class IB, and 8/45 (17.7%) had class 2. 24 samples were analyzed by FISH: 14 with disomy 3, 5 with complex disomy 3 with gain of chromosome 6 or 8, and 5 with monosomy 3. Conclusions: Similarly to general population, most of younger patients with melanoma are diagnosed with stage I disease. Among patients with stage III melanoma treated with adjuvant immunotherapy 1-year DFS was comparable to the general population. Patients with stage III who did not receive adjuvant therapy had an excellent DFS which confirms that the decision on selecting patients for treatment was appropriate. The prognosis of younger patients with uveal melanoma was much better than predicted by molecular testing, and much better than expected regardless of gene expression profile or cytogenetic testing.

High Levels of Chromosomal Copy Number Alterations and TP53 Mutations Correlate with Poor Outcome in Younger Breast Cancer Patients

Prognosis in young patients with breast cancer is generally poor, yet considerable differences in clinical outcomes between individual patients exist. To understand the genetic basis of the disparate clinical courses, tumors were collected from 34 younger women, 17 with good and 17 with poor outcomes, as determined by disease-specific survival during a follow-up period of 17 years. The clinicopathologic parameters of the tumors were complemented with DNA image cytometry profiles, enumeration of copy numbers of eight breast cancer genes by multicolor fluorescence in situ hybridization, and targeted sequence analysis of 563 cancer genes. Both groups included diploid and aneuploid tumors. The degree of intratumor heterogeneity was significantly higher in aneuploid versus diploid cases, and so were gains of the oncogenes MYC and ZNF217. Significantly more copy number alterations were observed in the group with poor outcome. Almost all tumors in the group with long survival were classified as luminal A, whereas triple-negative tumors predominantly occurred in the short survival group. Mutations in PIK3CA were more common in the group with good outcome, whereas TP53 mutations were more frequent in patients with poor outcomes. This study shows that TP53 mutations and the extent of genomic imbalances are associated with poor outcome in younger breast cancer patients and thus emphasize the central role of genomic instability vis-a-vis tumor aggressiveness.

Clinical Characteristics and Prognosis of Young Patients with Coronary Heart Disease.

BackgroundThe objective of this study was to investigate the clinical characteristics and prognosis of coronary heart disease (CHD) in young patients.Material/MethodsWe included 972 CHD patients (≤50 years old) with coronary artery stenting who were prospectively enrolled and followed for 1 year. Clinical characteristics, risk factors, and predictors of outcomes were evaluated.ResultsThe prevalence of current smoker, hypertension, diabetes mellitus, dyslipidemia and positive family history of CHD were 18.9%, 34.3%, 14.5%, 4.4%, and 44.2%, respectively. Most of the patients underwent coronary stenting due to stable angina (48.8%) and unstable angina (UA; 48.1%). After 1-year follow-up, 64 patients (6.6%) experienced clinical outcomes and the most common event was UA (n=56). Compared to patients without clinical outcomes, those with outcomes were more likely to be male, have higher systolic blood pressure, more likely to have hypertension and diabetes mellitus, and more likely to be presented as unstable angina. Multivariate regression analysis showed only age (hazard ratio [HR]: 1.12 and 95% confidence interval [CI]: 1.07–1.26), smoking (HR: 1.15 and 95% CI: 1.06–1.23), presence of hypertension (HR: 1.19 and 95% CI: 1.13–1.31), and diabetes mellitus (HR: 1.16 and 95% CI: 1.09–1.28), more vessels with stenosis (HR: 1.27 and 95% CI: 1.20–1.48) and presented with acute coronary syndrome (HR: 1.35 and 95% CI: 1.21–1.55) were independently associated with clinical outcomes.ConclusionsMost of the young (≤50 years of age) CHD patients had poor management of risk factors and better controlling these risk factors would be helpful for the primary and secondary prevention of premature CHD in Guangdong province.

HPV Involvement in the Tumor Microenvironment and Immune Treatment in Head and Neck Squamous Cell Carcinomas.

Head and neck squamous cell carcinomas (HNSCC) are one of the most prevalent cancers worldwide. Active human papillomavirus (HPV) infection has been identified as an important additional risk factor and seems to be associated with a better prognosis in non-drinker and non-smoker young patients with oropharyngeal SCC. The better response of the immune system against the HPV-induced HNSCC is suspected as a potential explanation for the better prognosis of young patients. To further assess this hypothesis, our review aims to shed light the current knowledge about the impact of HPV infection on the immune response in the context of HNSCC, focusing on the innate immune system, particularly highlighting the role of macrophages, Langerhans and myeloid cells, and on the adaptative immune system, pointing out the involvement of T regulatory, T CD8 and T CD4 lymphocytes. In addition, we also review the preventive (HPV vaccines) and therapeutic (checkpoint inhibitors) strategies against HPV-related HNSCC, stressing the use of anti-CTLA4, PD-L1, PD-L2 antibodies alone and in combination with other agents able to modulate immune responses.

Analysis of clinicopathological features and prognosis of young patients with breast cancer in different age groups

Analysis of clinicopathological features and prognosis of young patients with breast cancer in different age groups

Abstract P5-12-08: The effect of adjuvant endocrine therapy adherence on breast cancer prognosis according to age group

Abstract Background: It is well known that the young age at the diagnosis of breast cancer is a bad prognostic factor, by many previous studies. In a study of breast cancer adherence to adjuvant endocrine therapy (AET), younger patients were found to have significantly lower adherence. Therefore, the poor prognosis of young patients, with hormone receptor positive breast cancer, should be figured out whether it is due to the difference in adherence. And we aimed to analyze the effect of medication adherence for 4.5 years on subsequent prognosis, after the treatment completion. Methods: A total of 5,928 patients with stage I~III hormonal receptor positive breast cancer, who underwent surgery at Asan Medical Center from January 1997 to December 2009 were included in this retrospective analysis. Patients with no history of AET, follow-up loss, early breast cancer recurrence within 4.5 years from initial treatment were excluded. The number of days of treatment gap was estimated by subtracting the duration of medication coverage from the intervals between prescription dates. A descriptive analysis of prescription gap according to age distribution was done. And a multivariate Cox regression for the risk of distant metastasis of breast cancer by AET adherence, grouped by; no gap, gap1, gap2 (gap1: prescription gap within median, gap2: gap over median) according to age group (grouped by the age at diagnosis of &amp;lt;40, 40~59, and ≥60), was conducted. Results: The AET adherence was best in the middle-age group, showing the smallest number of days in treatment omission (130.9/4264, mean of total prescription gap/number of patients), compared with young (194.9/959) or old group (159.4/705). When adjusted with cancer stage, histologic grade, adjuvant treatment of chemotherapy or radiation therapy, type of AET agent, the risk of distant metastasis with increasing gaps tended to increase in the younger age group but it showed no significance between three gap-groups (p=0.063). The risk was significantly increased in the older age group, that the hazard ration (HR) in gap1 group was 2.534 (95% CI: 0.845~7.599, p=0.097), and 3.820 (95% CI 1.485~9.828, p=0.005) in gap2 group. With the reference of middle-age-no gap group, younger-no gap group showed significantly high HR (1.853, 95% CI: 1.008~3.407, p=0.047). In older age groups, only gap2 group showed significantly high HR (2.605, 95% CI: 1.443~4.703, p=0.001). However, in the risk of distant metastasis, the interaction between the gap and age difference was not statistically significant (p = 0.487). Conclusion: In distant metastasis after AET completion, both adherence and age at diagnosis showed a strong correlation. This suggests that survival after 4.5 years in young patients could be more affected by other factors (besides compliance with medication). This implicates that the prophylactic effect of AET after the end of the routine medication period is less significant. Further analysis including patients with early recurrence is needed in the future. Citation Format: Yura Lee, Hee Jeong Kim, Sun Ok Kim, Jong Won Lee.

Independent factors FOR poor prognosis in young patients with stage I-III breast cancer.

SUMMARYBreast cancer is the most common malignancy in the population of women under 40 years of age. Young age is an independent factor for poor prognosis. In this research, we tried to establish other factors for poor prognosis in stage I-III breast cancer. The following parameters were observed: tumor size, lymph node status, histologic grade, hormonal receptor status, Ki-67 prognostic index, Her2 neu status, histologic type of the tumor, local recurrence and metastases. Logistic regression was used to evaluate the effect of specific factors on the probability of lethal outcome and development of distant metastases. Our patients showed a predominance of T1 tumor (49.4%), had positive lymph nodes (62%) and most of them were pN1 (61.2%). Up to one-third of patients had triple negative status. Ki-67 proliferation index was high (25%). Multicentric tumor was detected in 23% of patients. There was no difference in overall survival between the two types of surgical procedures. Patients with pN0 status had better overall survival. Breast cancer in the population of young women has a more aggressive nature. Study results indicated positive lymph node status as an independent factor for poor prognosis of stage I-III breast cancer.
