Relation of Mean Platelet Volume (MPV) with Cancer: A Systematic Review with a Focus on Disease Outcome on Twelve Types of Cancer

Inflammatory proteins activate platelets, which have been observed to be directly related to cancer progression and development. The aim of this systematic review is to investigate the possible association between Mean Platelet Volume (MPV) and cancer (diagnostic capacity of MPV, relation to survival, the severity of the disease, and metastasis). A literature review was performed in the online database PubMed and Google Scholar for the period of 2010-2022. In total, 83 studies including 21,034 participants with 12 different types of cancer (i.e., gastric cancer, colon cancer, esophageal squamous cell carcinoma, renal cancer, breast cancer, ovarian cancer, endometrial cancer, thyroid cancer, lung cancer, bladder cancer, gallbladder cancer, and multiple myeloma) were identified. The role of MPV has been extensively investigated in several types of cancer, such as gastric, colon, breast, and lung cancer, while few data exist for other types, such as renal, gallbladder cancer, and multiple myeloma. Most studies in gastric, breast, endometrium, thyroid, and lung cancer documented an elevated MPV in cancer patients. Data were less clear-cut for esophageal, ovarian, and colon cancer, while reduced MPV was observed in renal cell carcinoma and gallbladder cancer. Several studies on colon cancer (4 out of 6) and fewer on lung cancer (4 out of 10) indicated an unfavorable role of increased MPV regarding mortality. As far as other cancer types are concerned, fewer studies were conducted. MPV can be used as a potential biomarker in cancer diagnosis and could be a useful tool for the optimization of treatment strategies. Possible underlying mechanisms between cancer and MPV are discussed. However, further studies are needed to elucidate the exact role of MPV in cancer progression and metastasis.

A Study of Platelet Count and Mean Platelet Volume in Newborn of Preeclamptic Mother

Introduction: Pregnancy is a physiological process. Preeclampsia is the commonest complication during pregnancy. This condition might severely affect the health of mothers and their newborns. Newborn of mothers with preeclampsia are more liable for intrauterine growth retardation and may be delivered prematurely. Aim of the Study: The aim of this study was to evaluate the platelet count and mean platelet volume in newborn of preeclamptic mother. Methods: This cross-sectional study was conducted in the Department of Physiology, Dhaka Medical College, Dhaka, Bangladesh from January 2017 to December 2017. Total 60 newborns were included in this study. The subjects were divided into 2 groups. Group A (Study group): Thirty (30) newborns of preeclamptic mother and Group B (Control group): Thirty (30) newborns of healthy pregnant mother. The subjects were selected from Department of Obstetrics and Gynecology, Dhaka Medical College Hospital, Dhaka on the basis of exclusion and inclusion criteria. Five (5) ml. of cord blood was collected from each newborn after delivery and was analyzed for Platelet count and mean platelet volume. These parameters were estimated in the Department of Hematology, Dhaka Medical College Hospital, Dhaka. Data were collected in pre- designed structured questionnaire form by the researcher herself. For statistical analysis Unpaired Student’s “t” test, Chi Square test and Pearson’s correlation coefficient (r) test were performed as applicable using SPSS for windows version 16.0. p value <0.05 was accepted as level of significance. Results: The mean (± SD) platelet count was 164.77 ± 79.44 × 103/µl and 212.83 ± 54.04 ×103/µl in group A and B respectively. In this study, the mean (±SD) platelet count was lower in group A in comparison to that of group B which was statistically significant (p<0.001). The mean (± SD) platelet volume was 8.90±1.15 fl and 8.30±1.45 fl in group A and B respectively. In this study, the mean (±SD) platelet volume was higher in group A in comparison to that of group B which was not statistically significant. Maternal systolic blood pressure showed negative correlation (- 0.952) with platelet count of newborn in preeclamptic mother, which was statistically significant (p<0.001). Maternal diastolic blood pressure showed negative correlation (- 0.960) with platelet count of newborn in preeclamptic mother, which was statistically significant (p<0.001). Maternal systolic blood pressure showed negative correlation (-0.973) with mean platelet volume of newborn in preeclamptic mother, which was not statistically significant (p>0.05). Maternal diastolic blood pressure showed negative correlation (-0.964) with mean platelet volume of newborn in preeclamptic mother, which was not statistically significant (p>0.05). Conclusion: From the findings of the study, it can be concluded that the platelet count of newborn of preeclamptic mother was significantly lower in comparison to newborn of healthy pregnant mother but they were within normal range. This difference was significantly related to severity of maternal blood pressure. But there was no statistically significant difference in mean platelet volume between the groups. There was no statistically significant relation of mean platelet volume to maternal blood pressure.

To determine the relation of mean platelet volume with diabetes mellitus

Background: Diabetes mellitus (DM) is a complex metabolic disorder portrayed by chronic hyperglycemia bringing about intricacies influencing the peripheral nerves, kidneys, eyes, and macrovascular structures. Mean platelet volume (MPV) is also considered to impact the advancement of microvascular complications of diabetes mellitus which has been looked for in this study. Aims and Objectives: The aims of this study were as follows: (1) To study association of MPV with Nephropathy and Retinopathy in Diabetes. (2) To Study correlation of MPV with hemoglobin A1c (HbA1C), fasting blood sugar, post-prandial blood sugar, and body mass index (BMI). Materials and Methods: This was an observational study conducted over 18 months period on patients (both males and females) seeking medical attention for newly diagnosed or previously diagnosed DM. Selective sampling technique was used and 200 diabetic patients were enrolled in the study during the study period. Results: (1) The incidence of retinopathy and increased Hba1c was significantly higher in poorly controlled diabetics as compared to controlled diabetics. (2) In good glycemic control group, mean MPV was 8.58 fL and, in poor glycemic control group, mean MPV was 10.21 fL. Conclusion: There was a positive correlation between MPV and HbA1C, microalbuminuria, BMI, fasting, and post-prandial blood sugar levels. There was no significant association between MPV and retinopathy.

The role of mean platelet volume in nonalcoholic fatty liver disease without cardiovascular comorbidities, obesity and diabetes mellitus.

While the relation of mean platelet volume (MPV) with inflammatory diseases is obvious, its role in nonalcoholic fatty liver disease (NAFLD) without cardiovascular comorbidities, obesity and diabetes mellitus is not clear. A total of 249 patients (nonobese, nondiabetic and not having cardiac diseases) who underwent an abdominal ultrasonography assessment were enrolled. They were divided according to the absence (group 1) or presence (group 2) of hepatic steatosis. The patients with steatosis were further divided according to the severity of steatosis as group 2a (grade 1), 2b (grade 2) and 2c (grade 3). The demographic and laboratory features were compared between groups. Hepatic steatosis was absent in 120 patients and detected in 129 patients (grade 1, 2, 3 hepatic steatosis in 75, 49 and 5 patients, respectively). BMI, aspartate aminotransferase/alanine aminotransferase (AST/ALT) ratio and serum AST, ALT, triglyceride levels were significantly higher in group 2 than in group 1 (P < 0.001, P < 0.001, P < 0.001, P = 0.005, P < 0.001, respectively). BMI, serum AST and triglyceride levels were significant factors for NAFLD (P < 0.001, P = 0.018, P = 0.001). MPV was neither different between groups (P > 0.05) nor a predictor factor for NAFLD (P > 0.05). MPV is a useless parameter to detect NAFLD without cardiovascular comorbidities, obesity and diabetes mellitus.

Objective: Obesity is an important health problem, which affects children and adolescents and is highly prevalent throughout the world. Non-alcoholic fatty liver disease is liver fattening that occurs due to non-alcohol causes, and it is associated with obesity in most of the cases. We aimed to evaluate the relation of mean platelet volume (MPV) and neutrophil-to-lymphocyte ratio (NLR) to hepatosteatosis in obese children in our study. Material and Methods: A total of 104 obese children aged between 4-16 years, who were determined to have a body mass index (BMI) of 95th percentile or higher according to age and gender, were examined retrospectively. The genders, ages, and examination findings of the patients were recorded. In obese children, leukocyte, hemoglobin, platelet, mean platelet volume, neutrophil and lymphocyte levels were assessed in the complete blood count performed during the first application. Neutrophil-to-lymphocyte ratio was calculated. Fasting blood glucose (FBG) and fasting insulin, serum aminotransferase values and ultrasonographic results of the patients were recorded. Results: Hepatosteatosis was determined in 64 of 104 patients (61.53%) while it was not determined in 40 patients (38.47%). The BMI, fasting insulin, HOMA-IR, and ALT levels were higher in patients with hepatosteatosis than in the group without hepatosteatosis. The average MPV of the group with hepatosteatosis was 7.78±1.57, and the average MPV of the group without hepatosteatosis was 7.42±1.43, and no statistically significant difference was observed between the groups in terms of the average MPV (p=0.236). The average NLR was 1.62±1.06 in the group with hepatosteatosis and 1.38±0.59 in the group without hepatosteatosis. There was no statistically significant difference between the NLR averages of the groups with and without hepatosteatosis (p=0.200). Conclusion: In the present study, no relation was determined between MPV and NLR and liver fattening in obese children.

Is mean platelet volume a predictor of atherosclerosis in hemodialysis patients?

Aim: Cardiovascular (CV) mortality accounts for the 45% of all mortality in dialysis. Carotid intima-media thickness (CIMT) is a preclinical marker for CV disease. Activated platelets pose important part of the cellular component in the pathophysiology of atherothrombosis. Mean platelet volume (MPV) is a parameter that indicates the activation of platelets and assessed by studies in various patient groups in atherosclerosis. The aim of this study is to determine the relation of MPV with CIMT in haemodialysis (HD) patients without a history of atherosclerosis. Materials and Methods: Eighty two HD patients and 20 healthy individuals were enrolled in this cross-sectional study. Ultrasonographical B-mode imaging of bilateral carotid arteries was performed with a high resolution real-time ultrasonography with 12MHz linear-assay transducer (Mindray DC7). The value was expressed as an average of the maximal CIMT. MPV was measured by automated devices. Results: CIMT was found to be higher in study population when compared to control group. MPV was not different between groups (8.40±0.85 vs 8.4±0.81; P>0.05). In correlation analysis CIMT was found to be positively correlated with age(r=0.326; P=0.003), ALP(r=0.309; P=0.005) and MPV(r=0.26; p= 0,017). Patients were grouped according to median levels of MPV. The patients having higher MPV values were found to have higher PTH (533.9 ± 458.3 vs 845.8 ± 860.2; P

The relation of mean platelet volume with microalbuminuria and glomerular filtration rate in obese individuals without other metabolic risk factors: the role of platelets on renal functions.

Mean platelet volume (MPV) is an indirect indicator of platelet activity that plays a major role in the pathogenesis of endothelial injury. Obese individuals have higher microalbuminuria which is the initial step of renal endothelial injury. We aimed to analyze the relation of microalbuminuria and MPV in obese individuals without metabolic risk factors. A total of 290 obese individuals (body mass index (BMI)>30 kg/m2) without an accompanying chronic disorder, and 204 nonobese healthy subjects were enrolled into the study. All participants underwent physical examination. Biochemical, hemogram, and hormonal parameters along with urine albumin analysis were performed. Glomerular filtration rate (GFR) was measured by Cockcroft-Gault (GFRC&G), modification of diet in renal disease (MDRD). The BMI was calculated as weight/height2 (kg/m2). Logistic regression analysis was used to analyze relation of variables. The patient group consisted of 171 (59%) female (mean age: 37.15±8.05 years) and 119 (41%) male (mean age 38.98±10.68 years) obese individuals. 130 (63.7%) age matched female (mean age 36.18±8.26 years) and 74 (36.3%) age matched male (mean age 36.49±10.25 years) controls were assigned to the control group. There was a significant difference between groups with regard to BMI, spot microalbuminuria, spot urine microalbuminuria/creatinine ratio but not with to MPV and spot urine creatinine (p: 0.01, 0.004, 0.002; respectively). GFR measured by MDRD and Cockcroft-Gault formula were significantly higher in the obese group (p<0.001 for both). Correlation analysis revealed a significant correlation between BMI and spot urine microalbuminuria, spot urine microalbuminuria/creatinine ratio, GFR (Cockcroft-Gault Formula), Homeostasis Model Assessment of Insulin resistance (HOMA-IR), insulin, C-peptide, diastolic blood pressure, glucose, uric acid, total cholesterol, low density lipoprotein (LDL)-cholesterol, c-reactive protein (CRP), thyroid stimulating hormone (TSH), leukocyte count, platelet count. MPV was inversely and significantly correlated with spot urine creatinine, systolic blood pressure, triglyceride, C-peptide, and platelet count. Mean urea, creatinine, uric acid, triglyceride, total cholesterol, LDL-cholesterol, insulin, C-peptide, HOMA-IR were significantly higher in obese male individuals while obese female individuals had higher levels of mean high density lipoprotein (HDL), CRP, TSH, platelet count, spot urine microalbumin/creatinine rate, and GFR measured by MDRD. Obese individuals have higher microalbuminuria and nonsignificantly elevated MPV, however, urine albumin loss is independent of MPV.

Relation of mean platelet volume with obstructive adenoid hypertrophy in children

ObjectiveAdenoid hypertrophy (AH) is a common etiology of chronic upper airway obstruction. Upper respiratory tract obstruction may cause chronic alveolar hypoventilation and pulmonary vasoconstriction. In one previous study in patients with obstructive sleep apnea (OSA), it has been claimed that mean platelet volume (MPV), an indicator of platelet activation is increased and that MPV has an important role in the pathophysiology of cardiovascular diseases. We investigated in our study if MPV can be used as an indicator of obstruction due to adenoid hypertrophy. MethodsOur study includes 61 children that underwent adenoidectomy with a mean age of 7.12 (±2.373). White blood cell, platelet count, MPV, platelet crit and platelet distribution width levels were measured before and 3 months after adenoidectomy. Children’s symptoms for upper airway obstruction (UAO) (presence of snoring, mouth breathing or difficulty in breathing during sleep, obstructive breathing or apnea during sleep) were questioned in the preoperative and postoperative period by a standardized questionnaire. ResultsThere was no significant difference between preoperative and postoperative mean values of MPV, hemoglobin, platelet count (p>0.05). White blood cell levels were significantly higher in the preoperative period values compared with postoperative period values (p<0.05). Preoperative UAO scores were significantly higher than the postoperative UAO scores. After stratification of the degree of obstruction (as mild, moderate and severe) there was no significant difference in between groups in terms of MPV values. ConclusionThere was no significant relation between MPV levels and obstructive adenoid hypertrophy.

Relation of Mean Platelet Volume with Subclinical Atherosclerosis in Patients with Metabolic Syndrome

PP-330 Metabolic syndrome (MetS) is associated with increased cardiovascular morbidity and mortality. There is evidence of platelet activation in MetS. Mean platelet volume (MPV), a determinant of platelet activation, is a newly emerging risk factor for atherothrombosis. Therefore, we have

Mean platelet volume in biopsy-proven non-alcoholic fatty liver disease

Non-alcoholic fatty liver disease (NAFLD) is increasingly recognized as the most common cause of chronic liver disease worldwide. It has been shown that NAFLD has a strong association with metabolic syndrome and its component like insulin resistance (IR). Cardiovascular disease has a relation with NAFLD. Platelet volume is an indicator of platelet function and activation. Mean platelet volume (MPV) has been reported as a risk factor for atherothrombosis. In our study, we aimed to investigate the relation of MPV with NAFLD and IR in the NAFLD patients. A total of 54 patients with histologically proven NAFLD and 41 healthy age-matched control subject were enrolled in this study. The NAFLD subjects were divided into two subgroups: 42 patients in the insulin resistant group (median age 39.5, females 22 [52%]) and 12 patients in the insulin sensitive group (median age 38, females 5 [41.7%]). MPV were significantly higher in the NAFLD group in univariate analysis (p < 0.05). In the NAFLD patients, we did not find any relation between steatosis grade, lobular inflammation, hepatocellular ballooning, NAFLD activity score and fibrosis with MPV value. Among the insulin resistant and sensitive groups in the NAFLD patients MPV values were similar. The results of this study showed that MPV, an indicator of platelet activation, increased in biopsy proven NAFLD patients but MPV is not correlated with the increase of IR in NAFLD patients. MPV is not related with inflammation and steatosis degree, hepatocellular ballooning and fibrosis in NAFLD patients.
