D-dimer levels as marker of deep vein thrombosis in patients with cervical cancer: A study of a northern Nigerian patient population

Background: Cervical cancer is the most common genital tract malignancy in Nigeria and an important cause of cancer­related death in women. Patients with advanced cervical cancer are often victims of deep venous thrombosis (DVT) that increases morbidity and mortality. Strategies at screening and early diagnosis enable prompt treatment which improves quality of life. Objectives: The objective of this study is to determine the plasma D­dimer level in patients with cervical cancer and its relationship to the presence of DVT,Well's score, and stage of malignancy. Materials and Methods: It is a prospective cross-sectional descriptive study of patients with histological diagnosis of cervical cancer in a Nigerian population. Patients' clinical, laboratory, and radiological data were obtained, and their body mass index (BMI) was calculated. Well's chart 17 was used to categorize patients using a cutoff of 2. Plasma D­dimer was quantified by immunoturbidimetric method and interpreted as significant if >0.099 g/dl.High­resolution ultrasound with 5­10 MHZ linear probe was used to evaluate the lower limbs veins of the patients. Data were analyzed with SPSS version 20. The test of association was done using Chi­square with a P < 0.05 considered statistically significant. Results: A total of 77 patients were enrolled, but 67 patients had complete data. The mean age was 54.7 ± 11.2 years. The average parity was 7.5 ± 3.1. Majority (47.8%) had normal BMI. D­dimer was positive in 58 (87%). Of the 17 (25%) with both elevated D­dimer and high probability of DVT, 5 (29%) had DVT. The incidence of DVT among our study population was 7.5%. There was statistically significant relationship between stage of diseaseand an elevated D­dimer value (χ2 = 5.82, α = 0.016, 95% confidence interval). Conclusion: Deep vein thrombosis occurred only in patients with high D­dimer and high Well's score, which makes their combination relevant in early diagnosis. Advanced age, high parity advanced stage of disease was the main associated risk factors. All cases with DVT occurred in patients with squamous cell cancer

Epidemiology of ovarian cancers in Zaria, Northern Nigeria: a 10-year study.

BACKGROUND: Globally, the absence of a premalignant stage of ovarian cancer and a reliable screening tool make early diagnosis difficult. Locally, poverty, ignorance, and lack of organized cancer services make prognosis poor. We describe the epidemiological features of ovarian cancer seen at Ahmadu Bello University Teaching Hospital Zaria, Northern Nigeria, a tertiary referral center, over a 10-year period in this challenging setting. METHODS: All cases of histologically diagnosed ovarian cancer between January 1, 2004 and December 31, 2013 were included in the study. Case notes were retrieved to collect clinical data including age, parity, clinical stage of disease at presentation, and known associated factors. Results were analyzed using Epi info™. RESULTS: A total of 78 patients were included in the study. About 4-13 cases were seen every year with a tendency to increasing incidence. The patients were aged 8-80 years with mean of 37 years. Sixty-two (79.5%) patients were premenopausal while postmenopausal women accounted for only seven cases or 9.0%. There were 17 cases (22.3%) of aggressive cancers in patients aged ≤20 years. A majority of the patients, 65 (83.3%), were parous with only nine (11.5%) patients being nulliparous. Serous cyst adenocarcinoma accounted for 32 (41%) cases. Granulosa cell tumor was the second commonest with 18 cases (23.1%). The mean age of occurrence of serous cyst adenocarcinoma was 31 years and for epithelial ovarian cancers in general it was 33.5 years. Endometrioid adenocarcinoma was rare with only one case in 10 years. Factors like age, parity, and premenopausal status did not appear to be protective to the occurrence of malignant ovarian tumor in this group. CONCLUSION: Increasing numbers of patients with ovarian cancer were seen over the 10-year period. Young, premenopausal, parous women made up the majority of cases. Serous cystadenocarcinoma was the most common histological variant.
