Breast cancer is one of the most prevalent malignancies in women globally, characterized by diverse histological and molecular subtypes, each with varying clinical outcomes. Understanding these subtypes and their associated risk factors is critical for accurate diagnosis, prognosis, and treatment planning.
The study scrutinized 187 breast cancer (BC) patients from Hail region of Saudi Arabia, focusing on ABO blood group distribution, histological type, cancer subtype, metastases size, age distribution, body mass index (BMI), gestational diabetes mellitus (GDM) status, and biochemical markers, including plasma calcium, magnesium, and HBA1C levels.
Blood group distribution showed O+ (50.27%) as the most common blood type, followed by A+ (14.97%) and B+ (11.2%). Histologically, Invasive Ductal Carcinoma (IDC) accounts for 64.1% (120) cases, while Triple Negative Breast Cancer (TNBC) constitutes 17.1% (32) cases. The most common metastatic sites are the lungs (25.1%) and axillary lymph nodes (17.6%). HER2-positive breast cancer, seen in 9.1% of cases, can lead to multi-organ metastases in some cases. Age distribution indicated most patients were 46-55 years old (50 cases), while BMI data exhibited the highest frequency in the obese category (~90 cases), with 12 having GDM and 177 not having GDM. Calcium levels across age groups slightly fell below the typical adult range (2.1-2.6 mmol/L) with an average of around 2.06 mmol/L. Magnesium levels were elevated in patients less than 35 years of age (7.02 mmol/L) and were low in other groups. HbA1C levels in all age groups ranged from 6.44 to 6.67 mg/dL, aligning with prediabetic or diabetic thresholds. Plasma calcium and magnesium levels were elevated in the weight category, showing slight deviations from the normal range. Underweight patients displayed the lowest HbA1C levels with all weight categories exceeding 6.5 mg/dL, indicating diabetes.
The results highlight IDC as a predominant BC type, with O+ as the most common blood group among patients. TNBC remains a treatment challenge due to a lack of hormone receptors. Metastases mainly affect the lungs and lymph nodes. Elevated BMI, calcium, and magnesium levels correlate with increased HbA1C, suggesting a diabetic link. Emphasizing personalized treatment, obesity management, and electrolyte monitoring., the present research advocates a holistic approach for improved BC outcomes and suggests future exploration of metabolic influences.
