Effects of hypertension on cancer survival: A meta-analysis

Association between insulin resistance, metabolic syndrome and its components and lung cancer: a systematic review and meta-analysis

BACKGROUND

A growing body of evidence points to the association between insulin resistance (IR), metabolic syndrome (MetS) and its components and lung cancer incidence, but remains controversial and unknown.

METHODS

A systematic search was conducted through PubMed, Embase, Cochrane Library, the China National Knowledge Infrastructure (CNKI) and Wanfang databases for the corresponding studies. Each study reported the risk estimate and 95% confidence intervals (CI) for lung cancer, and a fixed effects model or random effects model was used for outcome.

RESULTS

We included 31 publications involving 6,589,383 people with 62,246 cases of lung cancer. Diabetes mellitus (DM) (RR = 1.11, 95% CI  1.06-1.16, P = 0.000) and IR (RR = 2.35, 95% CI  1.55-3.58, P = 0.000) showed a positive association with lung cancer risk. BMI (RR = 0.66, 95% CI  0.54-0.81, P = 0.000) and HDL-C (RR = 0.88, 95% CI  0.79-0.97, P = 0.010) were negatively correlated with lung cancer. MetS(RR = 0.99, 95% CI  0.90-1.09, P = 0.801), TC (RR = 0.93, 95% CI  0.81-1.06, P = 0.274), TG (RR = 0.99, 95% CI  0.88-1.12,P = 0.884), LDL-C (RR = 1.01, 95% CI  0.87-1.16, P = 0.928), hypertension (RR = 1.01, 95% CI  0.88-1.15, P = 0.928), FBG (RR = 1.02, 95% CI  0.92-1.13, P = 0.677) and obesity (RR = 1.11, 95% CI  0.92-1.35, P = 0.280) were not associated with lung cancer.

CONCLUSION

Our study showed that the risk of lung cancer is correlated with DM, IR, BMI, and HDL-C. Timely control of these metabolic disorders may have a positive effect on preventing lung cancer. Trial registration Our study has been registered in the Prospective Register of Systematic Reviews (PROSPERO), ID: CRD42023390710.

Association between hypertension grades and cancer mortality among Japanese men and women

PURPOSE

We aimed to examine the association between hypertension grades and the risk of total and site-specific cancer mortality among Japanese men and women.

METHODS

In the Japan Collaborative Cohort Study, 27,332 participants aged 40-79 years were enrolled and followed up with their mortality until 2009. According to the measured blood pressure (BP) at baseline, we classified the participants into four BP categories based on 2018 European guidelines. The Cox proportional hazard models were used to calculate the multivariable hazard ratios (HRs) with 95% confidence intervals (CIs) of total and site-specific cancer mortality according to the hypertension category.

RESULTS

During the 18.5 years of median follow-up, 1,927 cancer deaths were documented. Grade 1 (systolic blood pressure [SBP] 140-159 mmHg or diastolic blood pressure [DBP] 90-99 mmHg) and grade 2-3 hypertension (SBP ≥ 160 mmHg or DBP ≥ 100 mmHg) were associated with an increased risk of total cancer mortality; the multivariable HRs were 1.17 (1.04-1.32) for grade 1, and 1.27 (1.09-1.47) for grade 2-3 hypertension compared to optimal and normal BP (SBP < 130 mmHg and DBP < 85 mmHg). Linear and positive associations were observed between SBP and DBP 10 mmHg increment and the risk of total cancer mortality; HRs were 1.06 (1.03-1.08) for SBP and 1.07 (1.02-1.11) for DBP of 10 mmHg increment. The excess risk was primarily found for esophageal, liver, and pancreatic cancer; the respective multivariable HRs of grade 2-3 hypertension vs optimal and normal BP were 2.57 (1.10-6.04) for esophageal, 1.67 (1.01-2.77) for liver, and 1.95 (1.17-3.23) for pancreatic cancer.

CONCLUSION

Hypertension was associated with the increased risk of total cancer mortality, primarily of esophageal, liver, and pancreatic cancer.

Antihypertensive Medication Adherence and Cardiovascular Outcomes in Patients With Cancer: A Nationwide Population-Based Cohort Study

Background Hypertension is an important cause of morbidity, which predisposes patients to major cardiovascular events and mortality. The aim of this study was to explore the association between adherence to antihypertensive medication and clinical outcomes in adult patients with cancer. Methods and Results Using the 2002 to 2013 Korean National Health Insurance Service-National Sample Cohort, we extracted adult patients with cancer treated with antihypertensive medications. Based on the medication possession ratio value, participants were divided into 3 groups: good (medication possession ratio ≥0.8), moderate (0.5≤ medication possession ratio <0.8), and poor (medication possession ratio <0.5) adherence groups. The primary outcomes were overall and cardiovascular mortality. The secondary outcome was cardiovascular events requiring hospitalization due to major cardiovascular diseases. Among 19 246 patients with cancer with concomitant hypertension, 66.4% were in the nonadherence group (26.3% were moderate and 40.0% were poor adherence group). Over a median of 8.4 years of follow-up, 2752 deaths and 6057 cardiovascular events occurred. Compared with the good adherence group, the moderate and poor adherence groups had a 1.85-fold and 2.19-fold increased risk for overall mortality, and 1.72-fold and 1.71-fold elevated risk for cardiovascular mortality, respectively, after adjustment for possible confounders. Furthermore, the moderate and poor adherence groups had a 1.33-fold and 1.34-fold elevated risk of new-onset cardiovascular events, respectively. These trends were consistent across cardiovascular event subtypes. Conclusions Nonadherence to antihypertensive medication was common in patients with cancer and was associated with worse clinical outcomes in adult patients with cancer with hypertension. More attention should be paid to improving adherence to antihypertensive medication among patients with cancer.

Serum Progesterone is Negatively Associated with Hypertension and Blood Pressure Indicators Among Men and Postmenopausal Women

Sex hormones have been shown to be negatively associated with hypertension, but the relationship between serum progesterone levels and hypertension has not been adequately studied. Therefore, we aimed to evaluate the association between progesterone and hypertension among Chinese rural adults. A total of 6222 participants were recruited, which included 2577 men and 3645 women. The concentration of serum progesterone was detected by liquid chromatography-mass spectrometer system (LC-MS/MS). Logistic regression and linear regression were used to assess the associations between progesterone levels and hypertension and blood pressure related indicators, respectively. Constrained splines were used to fit the dose-response relationships of progesterone with hypertension and blood pressure related indicators. Moreover, the interactive effects of several lifestyle factors and progesterone were identified by a generalized linear model. After fully adjusting the variables, progesterone levels were inversely associated with hypertension in men [odds ratio (OR): 0.851, 95% confidence interval (CI): 0.752, 0.964]. Among men, a 2.738 ng/ml increase in progesterone was associated with a 0.557 mmHg decrease in diastolic blood pressure (DBP) (95% CI: -1.007, -0.107) and a 0.541 mmHg decrease in mean arterial pressure (MAP) (95% CI: -1.049, -0.034), respectively. Similar results were observed in postmenopausal women. Interactive effect analysis showed that only a significant interaction was observed between progesterone and educational attainment on hypertension in premenopausal women (p=0.024). Elevated levels of serum progesterone were associated with hypertension in men. Except for premenopausal women, a negative association of progesterone with blood pressure related indicators was observed.

Interaction of anxiety and hypertension on quality of life among patients with gynecological cancer: a cross-sectional study

BACKGROUND

Patients with gynecological cancer are prone to anxiety, and many of them are accompanied by hypertension, which seriously affects the quality of life (QOL). The study was to explore the interaction of anxiety and hypertension on QOL, and the moderating effect of perceived social support (PSS) in the impact of anxiety and hypertension on QOL of patients with gynecological cancer.

METHODS

A cross-sectional study was conducted in 2020, and 566 patients have been collected from the Affiliated Hospital of China Medical University. The Self-Rating Anxiety Scale (SAS), the Functional Assessment of Cancer Therapy Genera tool (FACT-G), and the Multidimensional Scale of Perceived Social Support Scale (MSPSS) were used. The interaction was analyzed by additive model, and the moderating effect was conducted by regression analysis and the simple slope analysis.

RESULTS

We found that 68.8% of patients had poor QOL due to the interaction between anxiety and hypertension. The relative excess risk ratio (RERI) was 22.238 (95%CI:44.119-88.596); the attribution ratio (AP) was 0.688 (95%CI:0.234-1.142); The interaction index (S) was 3.466 (95%CI: 0.823-14.435). The interaction items of PSS and anxiety were negatively correlated with QOL (β = -0.219, P < 0.01) and explained an additional 4.0% variance (F = 68.649, Adjusted R² = 0.399, ΔR² = 0.040, P < 0.01); PSS and blood pressure interaction item was not associated with QOL (β = 0.013, F = 55.138, Adjusted R² = 0.365, ΔR² = 0.001, P = 0.730).

CONCLUSIONS

When anxiety and hypertension coexist, the QOL was affected. PSS played a moderating role in the impact of anxiety on QOL. Healthcare providers should take intervention measures to improve patients' social support to reduce the impact of anxiety on QOL.

Development and validation of a machine learning model for survival risk stratification after esophageal cancer surgery

Background

Prediction of prognosis for patients with esophageal cancer(EC) is beneficial for their postoperative clinical decision-making. This study's goal was to create a dependable machine learning (ML) model for predicting the prognosis of patients with EC after surgery.

Methods

The files of patients with esophageal squamous cell carcinoma (ESCC) of the thoracic segment from China who received radical surgery for EC were analyzed. The data were separated into training and test sets, and prognostic risk variables were identified in the training set using univariate and multifactor COX regression. Based on the screened features, training and validation of five ML models were carried out through nested cross-validation (nCV). The performance of each model was evaluated using Area under the curve (AUC), accuracy(ACC), and F1-Score, and the optimum model was chosen as the final model for risk stratification and survival analysis in order to build a valid model for predicting the prognosis of patients with EC after surgery.

Results

This study enrolled 810 patients with thoracic ESCC. 6 variables were ultimately included for modeling. Five ML models were trained and validated. The XGBoost model was selected as the optimum for final modeling. The XGBoost model was trained, optimized, and tested (AUC = 0.855; 95% CI, 0.808-0.902). Patients were separated into three risk groups. Statistically significant differences (p < 0.001) were found among all three groups for both the training and test sets.

Conclusions

A ML model that was highly practical and reliable for predicting the prognosis of patients with EC after surgery was established, and an application to facilitate clinical utility was developed.

Impact of Cardiovascular Diseases on Mortality in Gastric Cancer Patients with Preexisting Chronic Disease

PURPOSE

Chronic diseases and cardiovascular diseases (CVD) have been independently linked to poorer cancer outcomes. This study investigated whether gastric cancer patients with hypertension, diabetes, or dyslipidemia have higher mortality if diagnosed with CVD in the past year before cancer diagnosis.

MATERIALS AND METHODS

Data were obtained from the National Health Insurance database for 2002 to 2019. The study population consisted of gastric cancer patients with hypertension, diabetes, or dyslipidemia. The outcome measure was 5-year mortality in relation to incident status of CVD within 1 year before cancer diagnosis. A survival analysis was conducted using the Cox proportional hazards model. Subgroup analysis was conducted according to age, economic status, and type of hospital first visited for cancer treatment.

RESULTS

Of a total of 6458 individuals, 2123 (32.7%) were diagnosed with CVDs in the past year before cancer diagnosis. Compared to participants without a history of CVD, those who were diagnosed with CVD showed a higher risk of 5-year mortality (hazard ratio 1.259, 95% confidence interval 1.138-1.394). The extent to which the mortality risk differed between those with and without CVD was greater for individuals of low economic status and in those receiving their initial cancer treatment in a general hospital.

CONCLUSION

Patients with gastric cancer and hypertension, diabetes, or dyslipidemia diagnosed with CVD within 1 year before their cancer diagnosis had a higher mortality risk, emphasizing the importance of managing cancer patients with chronic disease and subsequent incidence of CVDs.

Prognostic value of long-term antidiabetic and antihypertensive therapy in postoperative gastric cancer patients: the FIESTA study

Background

Gastric cancer is often comorbid with hypertension and diabetes mellitus and increases the mortality risk.

Materials and methods

We conducted this prospective cohort study to investigate antidiabetics and antihypertensives’ impact on gastric cancer survival. 3012 patients with gastric carcinoma undergoing radical gastrectomy were enrolled since January 2000 and followed up until July 2020.

Results

Hypertension and diabetes patients had worse survival than patients without hypertension and diabetes [median survival time (MST): 48 versus 112.5 months, p < 0.001 for hypertension, MST: 32.7 versus 183+ months, p < 0.001 for diabetes]. Compared to untreated patients, treated patients had better survival (MST: 109.7 months versus 39.1 months, p < 0.001 for antihypertensives, MST: 120.9 months versus 22.3 months, p < 0.001 for antidiabetics). Antihypertensives and antidiabetics were related to 42% (HR 0.58, 95% CI 0.47–0.73, p < 0.001) and 70% (HR 0.30, 95% CI 0.24–0.38, p < 0.001) reduced mortality risk relative to those without medications. metformin and Calcium channel blockers can better-improved prognosis compared to others (p = 0.00029 and p = 0.015).

Conclusion

Post-surgical gastric cancer patients could benefit substantially from anti-diabetes and antihypertensive therapy. Metformin and Calcium channel blockers may be superior to other medications.

Can We Mitigate Coronary Heart Disease Risk in Patients with Cancer?

PURPOSE OF REVIEW

The review focuses on the shared risk factors observed between coronary heart disease and cancer, cancer therapeutics causing coronary heart disease, and potential strategies to mitigate atherosclerosis in patients with cancer.

RECENT FINDINGS

The pathophysiology behind how traditional cardiovascular risk factors also contribute to cancer development and mortality is increasingly recognized. In addition, newer cancer therapies, such as immune checkpoint inhibitors, cause increased inflammation leading to increased cardiovascular events. Traditional coronary heart disease risk factors such as obesity, hypertension, diabetes, and hyperlipidemia also contribute to cancer development and worse cancer outcomes. Cancer therapeutics can also lead to atherosclerotic events in addition to the shared risk factors present at the time of cancer diagnosis. Understanding the pathophysiology, using multidisciplinary care teams, and developing machine learning algorithms for individualized patient care will help to mitigate the risk of coronary heart disease in patients with cancer.

Triple-negative expression (ALDH1A1-/CD133-/mutant p53-) cases in lung adenocarcinoma had a good prognosis

Cancer stem cells (CSCs) are major contributors to the malignant transformation of cells because of their capacity for self-renewal. Aldehyde dehydrogenase1A1 (ALDH1A1) and CD133 are promising candidate of CSC markers in non-small cell lung cancer (NSCLC). Furthermore, TP53 is frequently mutated in lung cancer, and the loss of its function is associated with malignant characteristics. However, the relationship between CSCs and mutant p53 in lung adenocarcinoma is not well-established. We examined the expression of ALDH1A1, CD133, and mutant p53 in lung adenocarcinoma patients and conducted a clinicopathological study. Triple-negative cases without ALDH1A1, CD133, and mutant p53 expression in lung adenocarcinoma were shown to have a much better prognosis than others. Our present results suggest that detection of CSC markers and mutant p53 by immunohistochemical staining may be effective in therapeutic strategies for lung adenocarcinoma.
