RESUMO

Key Clinical Message: Describes a rare form of invasive breast cancer of no special type.Not a distinct morphological subtype.Characterized by dense lymphoid infiltrate, syncytial growth, pushing borders, and cells with high-grade nuclei.Clinically aggressive but carries a better prognosis than other more frequent invasive breast carcinomas. Abstract: Invasive breast carcinoma of no special type with medullary pattern (BCNST-MP) is a rare form of breast tumor, accounting for less than 5% of all invasive breast carcinomas. Its diagnosis is based on histologic criteria. Historically, this tumor was known as medullary carcinoma. Poor morphological reproducibility led to re-classification. Despite having an aggressive biological behavior, these tumors usually carry a better prognosis compared with other more frequent forms of invasive breast carcinomas. Herein, we present a case of BCNST-MP in a 58-year-old African female, successfully treated in our institution through chemo-radiation, hormonal therapy and surgery.

RESUMO

PURPOSE: Breast cancer (BC) is the second most common cancer among Tanzanian women. Oestrogen (ER), progesterone and human epidermal growth factor receptor 2 play major roles in prognosis and treatment but data for Tanzania are sparse. This study aimed to determine these patterns and histological types, tumour grading and staging of BC patients in northern Tanzania for a better understanding of BC in the Sub-Saharan African (SSA) setting. METHODS: A cross-sectional study recorded newly diagnosed BC cases at Kilimanjaro Christian Medical Centre between October 2018 and March 2019. Receptor status, histological types and grade, clinical stage and socio-demographic were recorded and descriptive and bivariate analyses performed. RESULTS: 116 patients were enrolled. Median age was 53 years, 71.6% were ≥45 years. The commonest molecular subtype was triple negative breast cancer (TNBC) (n = 33; 28.4%). One hundred and two (87.9%) patients had invasive ductal carcinoma (IDC), poorly differentiated tumours (60; 51.7%) and clinical stage III disease (62; 53.0%). ER negative tumours were associated with poorly differentiated histological grade (relative risk (RR): 1.34 (0.87-2.07)), tumour size > 5 cm (RR: 1.67 (0.33-8.35)) and IDC (RR: 3.35 (0.56-20.23)). Clinical stages III & IV (odds ratio (OR): 1.64 (0.63-4.24)) were associated with hormone receptor (HR) negative tumours and metastasis (OR: 1.60 (0.68-3.74)) with TNBC. 18% of the patients reported about first-degree relatives with BC. CONCLUSIONS: Most patients presented in advanced stages and TNBC in their menopause. HR negative tumours were associated with poor histological differentiation and IDC. The high percentage of positive family history of BC and the differences in receptor patterns compared to other parts of the world should urge further genetic research on BC in SSA.

RESUMO

BACKGROUND: The abdomen is one of the most commonly injured regions in trauma patients. Abdominal injury surgeries are common in Tanzania and in many parts of the world. This study aimed to determine the relationships among the causes, characteristics, patterns and outcomes of abdominal injury patients undergoing operations at Kilimanjaro Christian Medical Centre. METHODS: A prospective observational study was performed over a period of 1 year from August 2016 to August 2017. A case was defined as a trauma patient with abdominal injuries admitted to the general surgery department and undergoing an operation. We assessed injury types, patterns, aetiologies and outcomes within 30 days. The outcomes were post-operative complications and mortality. Multivariate logistic regression was used to explore the association between factors associated with morbidity and mortality. RESULTS: Out of 136 patients, 115 (84.6%) were male, with a male-to-female ratio of 5.5:1. The most affected patients were in the age range of 21-40 years old, which accounted for 67 patients (49.3%), with a median age (IQR) of 31.5 (21.3-44.8) years. A majority (99 patients; 72.8%) had blunt abdominal injury, with a blunt-to-penetrating ratio of 2.7:1. The most common cause of injury was road traffic accidents (RTAs; 73 patients; 53.7%). Commonly injured organs in blunt and penetrating injuries were, respectively, the spleen (33 patients; 91.7%) and small bowel (12 patients; 46.1%). Most patients (89; 65.4%) had associated extra-abdominal injuries. Post-operative complications were observed in 57 patients (41.9%), and the mortality rate was 18 patients (13.2%). In the univariate analysis, the following were significantly associated with mortality: associated extra-abdominal injury (odds ratio (OR): 4.9; P-value< 0.039); head injury (OR: 4.4; P-value < 0.005); pelvic injury (OR: 3.9; P-value< 0.043); length of hospital stay (LOS) ≥ 7 days (OR: 4.2; P-value < 0.022); severe injury on the New Injury Severity Score (NISS) (OR: 21.7; P-value < 0.003); time > 6 h from injury to admission (OR: 4.4; P-value < 0.025); systolic BP < 90 (OR: 3.5; P-value < 0.015); and anaemia (OR: 4.7; P-value< 0.006). After adjustment, the following significantly predicted mortality: severe injury on the NISS (17 patients; 25.8%; adjusted odds ratio (aOR): 15.5, 95% CI: 1.5-160, P-value < 0.02) and time > 6 h from injury to admission (15 patients; 19.2%; aOR: 4.3, 95% CI: 1.0-18.9, P-value < 0.05). CONCLUSION: Blunt abdominal injury was common and mostly associated with RTAs. Associated extra-abdominal injury, injury to the head or pelvis, LOS ≥ 7 days, systolic BP < 90 and anaemia were associated with mortality. Severe injury on the NISS and time > 6 h from injury to admission significantly predicted mortality.
