The severity, outcome and challenges of breast cancer in Nigeria.

Breast cancer is a very common disease in Nigeria. It is often associated with a poor prognosis for a variety of reasons. This study was designed to investigate the challenges, severity, outcome and factors influencing the outcome of the management of breast cancer in a Nigerian Teaching Hospital with a view to finding ways to improve the current dismal outlook for patients with the disease. The clinical records of patients seen with breast cancer over an 8-year period (1996-2003) in the two units of the Teaching hospital were reviewed. The two units serve the urban, semi-urban and rural communities of some parts of southwestern Nigeria. Two hundred and twelve patients with breast cancer were seen over the 8-year period of the study. The mean age was 48 years (23-85 years). There were 211 female and one male. One hundred and three patients (48.7%) had either postprimary or tertiary education. A proportion of 66.7% were premenopausal, 79.2% had pregnancy early in life and were multi-parous. These also gave a history of prolonged breast-feeding of their children. The tumour was self-detected in 195 (92%). The mean duration of symptoms was 11.2 months (9 days-7 years). Pain in 100 patients (47%) was the most common symptom and the cancer was in the left breast in 113 (53.3%). Localized cancer was in the upper outer quadrant in 85 (40%), whereas the whole breast was involved in 55 patients (26%). Loco-regional features of advanced cancer were seen in 157 patients (74%). The tumour was fungating in 83 (39%) and there was clinical evidence of systemic metastasis in 28 patients (13%). One hundred and seventy-four (80.6%) patients had advanced disease (stages 3 and 4). Definitive surgery was possible in 185 patients (87.3%), neoadjuvant chemotherapy was required in 65 (30.6%), postoperative adjuvant chemotherapy in 178 (84%; drug combinations were CMF-cyclophosphamide, methotrexate, 5-fluorouracil, CMFP-CMF plus prednisone, and CAF-cyclophosphamide, adriamycin, 5-fluorouracil), tamoxifen was administered in all the patients. Only 70 (33.2%) patients were known to have received radiotherapy among those referred to the Radiotherapy unit, with associated fair treatment compliance after surgery. Outpatient clinic attendance was also very poor, only 27 (12.7%) were still being seen in the clinic, 83 patients (39%) were known to be dead and 102 patients were lost to follow-up. The mean follow-up period was 8.4 months (1 week-6 years). In conclusion, breast cancer is very common in our area of practice in Nigeria; the majority of our patients were young and premenopausal women presenting in the advanced stages of cancer. Treatment compliance was very poor. The majority of the patients were dead or lost to follow-up within a year of diagnosis.

Studies on the acute and sub-chronic toxicity of the essential oil of Ocimum gratissimum L. leaf.

Oral and intra-peritoneal acute toxicity and the sub-chronic intra-peritoneal toxicity of the essential oil of Ocimum gratissimum Linn, Lamiaceae (Ocimum oil), was investigated. The acute toxicity test involved the oral and intra-peritoneal administration of graded doses of Ocimum oil prepared as a 4% v/v emulsion to 2 groups each of 30 rats and mice. LD50 and LD100 were determined for both routes and species. In the sub-chronic toxicity study, 25 male Sprague-Dawley rats were randomized into 4 test groups (treated with three graded sub-lethal doses of Ocimum oil prepared as a 4% v/v emulsion) and a control. Organs and blood samples were taken for analyses after a 30 day treatment period. A dose-dependent sedative effect of Ocimum oil was observed during the acute toxicity study in mice and rats and in the sub-chronic test in rats. Evidence of treatment, route, and dose-dependent toxicity were detected in both studies. Changes in weight of the testes, hearts, kidneys, intestines and lungs of the rats were statistically insignificant (ANOVA P < 0.05). Data analyses of blood biochemical, haematological and histopathological findings showed significant differences between control and treated groups and revealed that Ocimum oil is capable of invoking an inflammatory response that transits from acute to chronic on persistent administration. While the study revealed that Ocimum oil might be better tolerated when administered orally for systemic delivery, the oil has toxic potentialities that should not be overlooked.

Non Burkitt's non-Hodgkin's lymphoma in Ile-Ife.

To determine the frequency, age and sex patterns of non-Burkitt's non-Hodgkin's lymphoma among cases of lymphoma seen at the histopathology department of the Obafemi Awolowo University Teaching Hospitals Complex, Ile-Ife, Nigeria. The records of patients with histologically diagnosed non-Burkitt's non-Hodgkin's lymphoma seen over a period of five years were studied. The classification was based on the Working Formulation. The sex and the age at diagnosis as well as the sites of the lesions were noted. Of the fifty three cases of non-Burkitt's non-Hodgkin's lymphoma seen during the study period 54.7% had intermediate grade tumours; 24.5% has low grade and 20.8% had high grade tumours. 92.5% of the cases occurred in adults over the age of 20 years. There was also a male predominance. Nodal as well as extranodal sites were involved and peripheral lymph node involvement most often affected the cervical group of lymph nodes. The results showed that non-Burkitt's non-Hodgkin's lymphoma is predominantly a disease of adults which more often affected males than females. The intermediate grade type with the possibility of cure is the type most often seen in this study. Therefore, early diagnosis and preventive measures against known risk factors in our environment, where possible, are strongly recommended.

Hysterectomies in Nigerians: histopathological analysis of cases seen in Ile-Ife.

To review retrospectively hysterectomy specimens sent to the histopathological department of the Obafemi Awolowo University Teaching Hospitals Complex, Ile-Ife, Nigeria in order to document the histopathological findings and relate these with the age of patients. The records of patients with hysterectomy specimens sent to the histopathological laboratory within a period of 10 years were studied. Some of the histological slides were reviewed. The diagnosis of uterovaginal prolapse was based on clinical as well as pathological findings. Three hundred and thirty hysterectomy specimens seen over the study period of 10 years were studied. Women aged 40-49 years accounted for the highest number of cases, Hysterectomy was most often performed for leiomyoma (48%). followed by uterovaginal prolapse (17%). In women over the age of 70 years hysterectomy was most often performed for uterovaginal prolapse. Complication of pregnancy still accounted for a high percentage of hysterectomy (11%) Most were ante-partum and post partum haemorrhages as well as septic abortion in young women Ten of the specimens were normal both grossly and microscopically. Six of these were removed for suspected leiomyoma. The peak age incidence for women with leiomyoma who had hysterectomy corresponds with the overall peak age for women who had Hysterectomy. Leiomyoma was the commonest finding in hysterectomy specimens. However, clinicians should ensure that the condition is accurately diagnosed in all cases to avoid removal of a normal uterus.

Burkitt's lymphoma presenting as lower lip paraesthesia in a 24 year old Nigerian. Case report.

An unusual case of stage D Burkitt's lymphoma in a 24 year old Nigerian female undergraduate is reported. There was a four month history of left lower lip paraesthesia followed three months later by a slowly progressive 'pimple-sized' nodular mandibular swelling arising from the mental foramen region. A full-blown, rapidly developing abdominal mass manifested only three weeks after a biopsy of the mandibular swelling. Aspiration of the latter and a histologic report of the mandibular mass confirmed Burkitt's lymphoma. The patient responded very well to appropriate chemotherapy. Clinicians should not overlook insidious jaw swellings in any adult residing in the endemic zone of Burkitt's lymphoma, in view of the fact that successful therapy is dependent on early diagnosis. Mental nerve paraesthesia is very rarely seen in Burkitt's lymphoma.

Aflatoxins in autopsy kidney specimens from children in Nigeria.

Autopsy kidney specimens from 24 children with kwashiorkor and 21 with other miscellaneous diseases, at the Obafemi Awolowo Teaching Hospital Complex, Ile-Ife, Nigeria, were analyzed for the presence of aflatoxins using high-performance liquid chromatography. Aflatoxins were detected in 14 children who died of kwashiorkor and in 13 of those who died from miscellaneous diseases. Aflatoxicol was detected in 10 specimens, 7 of which had severe gastroenteritis. Seven kidney specimens demonstrated the presence of more than one type of aflatoxin; four of these were kidneys of patients with kwashiorkor and the remaining three died from renal failure. No difference was found between the frequency of detection, type of aflatoxin detected, or mean concentrations of total aflatoxins in the kidney specimens of the kwashiorkor children when compared to the kidney specimens of children who died from miscellaneous diseases. These findings demonstrate that aflatoxins can be detected in the kidneys of children exposed to aflatoxins.

Aflatoxins in the lungs of children with kwashiorkor and children with miscellaneous diseases in Nigeria.

Autopsy lung specimens from 20 children with kwashiorkor and 20 with other miscellaneous diseases, at the Obafemi Awolowo Teaching Hospital complex, Ile-Ife, Nigeria, were analyzed for the presence of aflatoxin using high-performance liquid chromatography. Aflatoxins were detected in 18 children who died from kwashiorkor but only in 13 of those who died from miscellaneous diseases. Of the 10 children, 5 in each group, who died with pneumonia, all had detectable levels of aflatoxins in their lungs. The two children with congestive cardiac failure, one secondary to pneumonia and the other secondary to tuberculous pericarditis, had more than two detectable aflatoxins in their lungs. These findings demonstrate that Nigerian children are exposed to aflatoxins and that high levels can accumulate in lung tissue.

Histopathological analysis of carcinoma of the male breast in Ile-Ife, Nigeria.

Carcinoma of the male breast is said to be rare. A review of the records at the histopathology laboratory of the Obafemi Awolowo University Teaching Hospitals Complex, Ile-Ife, confirms the universal assertion that carcinoma of the male breast is very rare. In over nineteen years of its existence, the laboratory recorded only 10 cases of carcinoma of the male breast. This gives an incidence rate of 1.9% of a total of 513 cases affecting both male and female breasts. All cases were infiltrating ductal carcinoma: there were two cases of papillary, one each of colloid and clear cell carcinoma while the remaining were "not otherwise specified". The age range was 40-80 years with an average of 56.9 years. There was left-sided preponderance with eight cases in the left breast and two cases in the right breast. Six cases had evidence of metastasis either at the time of initial diagnosis or some months after simple mastectomy.

Benign disease of the breast in Ile-Ife: a 10 year experience and literature review.

This study is a 10 year review of the benign diseases of the breast in Ile-Ife, Nigeria. A total of 362 cases were found. Three hundred and forty (95%) of the diseases occurred in females while 18 (5%) occurred in males giving a female-male ratio of 19:1. Fibroadenoma was the commonest lesion followed by fibrocystic disease. They accounted for 59.1% and 16.5% of benign breast diseases respectively. Acute and acute-on-chronic mastitis constituted 7.2%. These three lesions made up over 82% of the cases. Gynaecomastia was the commonest benign male breast disease and accounted for 3.8% of all the cases of benign breast disease. Apart from the atypical hyperplasia form of fibrocystic disease, benign diseases of the breast are not major predisposing lesions to malignant breast diseases.

Two unusual cases of kwashiorkor: can protein deficiency explain the mystery?

Two children with unusual features of kwashiorkor are reported. One, an exclusively breastfed 7-month-old girl, had been admitted earlier, treated for pneumonia and discharged 3 weeks before she presented with kwashiorkor. The other was an identical twin who was admitted for kwashiorkor and gastro-enteritis. The twin sister was underweight but relatively well. Both children died. Potent aflatoxins were detected in the organs of these children on post-mortem examination. The occurrence of kwashiorkor in a fully breastfed infant and in an identical twin does not accord with the extant belief that the aetiology of kwashiorkor is wholly nutritional, but suggests a disease probably of multifactorial origin.

Malignant solid tumours in Nigerian children.

The subject of neoplasia in African children has received little or no attention within the past two decades. The current study retrospectively reviews malignant solid tumours in children from birth up to the age of 15 years over an 11 year period in Ile-Ife, Nigeria. During this period, 71 pc of solid tumours seen in children were malignant and boys were more often affected than girls. The peak incidence was between the ages of six and 13 years. Lymphoma was the commonest type of tumour, accounting for 72.6 pc of all malignant solid tumours and males predominated. All the rhabdomyosarcomas were seen in boys and the alveolar variant predominated. Osteogenic sarcoma and nephroblastoma were more often seen in girls. No primary brain tumour was seen.

Abdominal injuries in Nigerian children.

A retrospective review of cases of abdominal injuries in children at the Obafemi Awolowo University Teaching Hospital in Nigeria show that 195 cases were seen over a 10-year period (1980-1989). A majority of the cases (83.6%) resulted from road traffic accidents, and 152 (77.9%) were either brought in dead or died shortly after arrival in the emergency room. The sex incidence was about equal. The spleen and liver were the two most commonly injured abdominal organs. However, there was a high incidence of multiple organ injury in those patients who died before treatment could be given. None of the 43 children who had clinical intervention died though one of the 12 children who had splenectomy subsequently developed postsplenectomy sepsis from which she recovered. Three children had splenorrhaphy and one had partial splenectomy with good results.

Lymphoma in adult Nigerians.

A review of 143 cases of lymphoma seen in adult Nigerians within a period of 10 years at the Obafemi Awolowo University Teaching Hospitals Complex, Ile-Ife, Nigeria. There were 95 males and 48 females patients with an age range of 17 to 88 years. There was male sex predominance both for Hodgkin's and non-Hodgkin's lymphoma. 74% of the cases were non-Hodgkin's lymphoma and 26% were Hodgkin's Nodular lymphomas were very few. Most cases of Hodgkin's disease were of the mixed cellularity subtype. Among non-Hodgkin's lymphomas the intermediate grade predominated, the commonest being diffuse large cell lymphoma. Cases of Burkitts's lymphoma were not common in young adults. Immunohistochemistry plays a vital role in lymphoma diagnosis and sometimes in the differential diagnosis with small blue cell tumours.

Lymphadenopathy in Nigerian children.

The histopathologic findings on 121 excised enlarged lymph nodes from 48 female and 73 male Nigerian children resident in Ife-Ijesa zone of Western Nigeria over a period of ten years (1982-1991) form the basis of this study. Patients' ages ranged from 2 months to 15 years. Most of the patients (81%) were aged 6 years and above. The cervical region was the commonest site of lymphadenopathy (48%) and localized lymphadenopathy was the rule. Chronic specific inflammation (tuberculosis, toxoplasmosis, and histoplasmosis) predominated as a cause of lymphadenopathy (44%) compared with non specific lymphadenitis (31%) and malignant tumours (24%). Tuberculosis was the commonest cause of chronic specific lymphadenitis and was commoner in girls. The cervical region was the commonest site for chronic specific lymphadenitis, as well as Hodgkin's and non-Hodgkin's lymphoma. The lymphomas were more common in males. The peak incidence for Hodgkin's disease was between the ages of 12 and 15 years.
