This article discusses the diagnosis and monitoring of patients with colorectal cancer using liquid biopsy. Colorectal cancer is one of the most common types of cancer worldwide; moreover, its diagnosis and monitoring is of great importance due to various factors such as lifestyle, environmental and genetic factors. There are various methods for diagnosing and monitoring colorectal cancer which can be used as the basis for selecting appropriate treatment methods such as surgery, chemotherapy, targeted therapy, immunotherapy, gene therapy and combination therapies.

Methods and Materials:

the current study has been performed through searching “Liquid biopsy”, “Colorectal Cancer”, “Tumor educated platelets”, “Biomarker”, and “Chemotherapy” keywords in various databases including PubMed, Scopus, Web of Science, and Google Scholar until Dec 2023. Out of the 297 articles, 49 articles were selected and they were included in the study based on the inclusion and exclusion criteria.

Liquid biopsy-based analysis of circulating tumor cells (CTCs), circulating tumor DNA (ctDNA), and tumor-educated platelets (TEPs) provide useful tools for early detection, monitoring treatment response, detecting disease recurrence, and identifying tumor heterogeneity and drug resistance mechanisms in colorectal cancer.

This article examines that due to the molecular characteristics of the tumor during the course of the disease and the genetic and phenotypic heterogeneity of the tumor between primary and metastatic lesions, liquid biopsy can be used as a new solution for diagnosis and monitoring of patients with colorectal cancer.

Colorectal and gastric cancers are among the most common types of cancers. Understanding the relationship between dietary factors and these cancers is crucial for preventing malnutrition and managing it in patients. This study aimed to conduct a comparative investigation into the nutritional intake and anthropometric indices of patients with non-metastatic colorectal and gastric cancer compared to a healthy control group.

In this descriptive, cross-sectional study, 167 participants, including gastric cancer patients (51 individuals), colorectal cancer patients (58 individuals), and a control group (58 individuals), were evaluated. Anthropometric parameters were measured using standard methods, and dietary intakes were assessed using a 24-hour dietary recall questionnaire. Subsequently, statistical analyses were performed using SPSS-21 software.

The study findings indicated that the body mass index, waist circumference, and waist-to-hip ratio were significantly higher in the control group (p< 0.01). Moreover, colorectal cancer patients exhibited higher ratios compared to gastric cancer patients (p < 0.01). Evaluation of dietary intakes in all three groups revealed a significantly lower intake of carbohydrates, proteins, fats, and energy in the gastric cancer group compared to the colorectal cancer group (p < 0.01). Additionally, in the gastric cancer group, the intake of energy, carbohydrates, proteins, and fats was significantly lower than in the other two groups (p < 0.05).

According to the results of this study, it appears that cancer patients exhibit significant differences in anthropometric indices and dietary intakes compared to non-afflicted individuals. It is recommended to involve specialized nutrition therapy groups to enhance their health status.

Multiple myeloma (MM) is defined as a plasma cell dyscrasia, accounting for approximately 10% of all hematologic malignancies. The aim of this study was to evaluate renal failure occurrence in MM patients admitted to Imam Khomeini Hospital in Urmia, Iran.

In this cross-sectional study, the files of patients with multiple myeloma were examined from March 2015 to March 2020. Also, the underlying diseases involved in the occurrence of kidney failure along with related risk factors such as hypercalcemia and infection were also investigated. Finally, the study data were analyzed using SPSS version 16.

According to the obtained results, the frequency of renal failure in the patients was 42.2%. The mean age of patients was 63.7±13.10 years, with a higher rate among men. Based on paraclinical assessments, the mean serum hemoglobin level (Hb) was significantly lower in patients with renal failure (P = 0.001). Also, the amount of hypercalcemia was significantly higher in the people with kidney failure (p<0.001). Hypertension was also seen significantly more in the patients with kidney failure as an important risk factor (p=0.01). Pathological fractures in the spine and skull bones were mainly observed in these patients. There was no significant difference in the prevalence of infection, serum levels of gamma globulin, albumin, and plasma cells between patients with and without renal insufficiency.

The results of this study showed that the prevalence of renal failure was higher in the patients with multiple myeloma, and as a result, it can be considered as one of the important tissue-damaging factors with a poor prognosis. Hypertension, anemia, and hypercalcemia were important prognostic factors in the occurrence of this complication.

Non-traumatic bone fractures are considered a pathologic condition with various etiologies, including cancer metastases, osteoporosis, and long-term corticosteroid consumption, which can affect people's quality of life. The main aim of this study was to investigate the etiology of pathological bone fractures in patients who were referred to the Hospital.

In this cross-sectional study, all patients with non-traumatic pathological fractures were included from March 2015 to February 2019 at Imam Khomeini hospital in Urmia city. Data analysis was calculated by chi-square test using SPSS.ver.17.

A total of 168 patients participated in this study, of which 108 patients (64.3%) were female, and 60 patients (35.7%) were male with a mean age of 58.6±21.1 with a minimum and maximum age of 7 and 90 years old, respectively. According to the results, the most common etiologies consist of osteoporosis (33.3%), metastatic carcinoma (28.6%), and primary tumor (11.3%), respectively. Regarding the anatomical site involved, vertebrae (57.1%) and the neck of the proximal femur (27.4%) were detected as the most frequent sites with fractures, respectively. Moreover, a significant relationship was found between the fracture etiologies and demographics data (age and gender) (p<0.001). In this regard, osteoporosis and metastatic carcinoma were reported as the most common fracture etiologies in females and males. In addition, intertrochanteric-subtrochanteric (7.7%), distal femur (4.8%), intertrochanteric (1.2%), and acetabulum (1.2%) were considered other sites of fracture with less frequency. It is worth noting that for patients with ages less than fifty years old (<50 years old), commonly reported fracture etiology was the primary osteosarcoma, while in patients with ages more than fifty (>50 years old), osteoporosis was defined as the main fracture etiology.

Together, the present study results showed that osteoporosis and metastatic carcinoma were the most critical etiology of fractures, and there was a statistical correlation between demographic characteristics (such as gender and age) and pathological fracture etiologies. According to the statistical results, the most common sites exposed for fractures were also the vertebral and proximal femur.
