RESUMO
OBJECTIVE: The aim of this study was to determine the adequacy of nodal sampling in resection specimens for colorectal carcinoma in a Jamaican population. METHODS: The pathology records of all patients who underwent operation for colorectal carcinoma at the University Hospital of the West Indies (UHWI) during the five-year period, 2003-2007, were reviewed. Pertinent clinical and pathologic data were obtained and analysed. RESULTS: One hundred and ninety-one patients were identified with M:F ratio of 1.1:1 and a mean age of 66 years. There were 119 (63%) left-sided lesions and 70 (37%) right-sided lesions. Stage T3N0 lesions were the most common and accounted for 41.1% of cases. The predominant histologic type was adenocarcinoma (99.5%) with the majority being moderately differentiated. The mean number of nodes sampled in node-negative cases was 13.8 +/- 9.75 nodes for right-sided lesions and 10.64 +/- 7.25 nodes for left-sided lesions (p = 0.05, CI 95%). The adequacy of nodal sampling was acceptable in cases of N0 right-sided carcinomas but was unsatisfactory in cases of N0 left-sided carcinomas. More importantly, however in two cases from the right and 10 cases from the left, two or fewer nodes were harvested. CONCLUSION: This review suggests the need for re-examination of the adequacy of surgical resection and/or nodal sampling technique for colorectal cancer resection specimens, given the importance of nodal status in determining the need for adjuvant therapy. Less than adequate node sampling should not be accepted by the reporting pathologist or attending surgeon as this has important prognostic implications.

OBJECTIVES: The aim of this study is to determine the prevalence and clinicopathological correlates of penile cancer as well as the clinical outcomes in a sample of Jamaicans managed at the University Hospital of the West Indies (UHWI). METHODS: All available records of patients diagnosed with penile cancer from 1998-2008 at the UHWI were obtained. Patient demographics, circumcision status, sexually transmitted infection status, lesion duration, location and size, and lymph node status were obtained. Histology, differentiation and stage were recorded. Information was obtained regarding treatment and outcome. The current data were compared with a previous report from UHWI in 1959. RESULTS: The records of 22 of 26 patients with penile cancer were available for review. Mean (SD) age of patients was 68 (13) years. Eighteen (86%) patients were uncircumcised Mean tumour size was 5.7 (2.6) cm; 8 (36%) lesions involved the entire penis. Sixteen (73%) lesions had clinically regional disease and 11 (52%) patients had advanced pathological stage. Surgical treatment was performed in 15 (68%) patients. Case fatality was 38%, with median survival following surgical intervention of 38 person-months. The major predictor of death in this series was increasing age (HR = 1.06, 95% CI 0.99, 1.1, p = 0.079). There was an increase in age and clinical stage of the cancer at presentation in the current series; however there was no difference in survival. CONCLUSION: Penile cancer is an uncommon cancer, seen at an advanced stage in Jamaicans. Overall survival is poor and advanced age is a major predictor of death.

OBJECTIVE: Angiomyolipoma (AML) of the kidney is an uncommon tumour that, until recently, was often misdiagnosed preoperatively as renal cell carcinoma (RCC). Newer radiological techniques have allowed more accurate preoperative diagnosis which can facilitate preoperative counselling and planning for conservative therapy. This study reviews the experience with these uncommon tumours at the University Hospital of the West Indies. METHODS: All cases of AML diagnosed during the period 1980 to 2007 were retrospectively identified from the files of the Department of Pathology. From these records, selected data were retrieved and analysed. These included patient demographics, clinical history, clinical diagnosis and pathologic characteristics of the specimen submitted. The total number of primary renal tumours diagnosed in adults during the same period was also determined for comparison. RESULTS: Eleven cases of AML were identified among 149 primary renal tumours in adults. Ten of these cases occurred in women. Amongst these, a single case of tuberous sclerosis was confirmed in a patient with bilateral lesions. Excluding this patient, who was 24-years-old, ages ranged from 24 to 86 years with a mean of 44 years (median 40.5 years) and an equal number of lesions was present on each side. Abdominal or flank pain were the most common clinical symptoms, present in six cases but in three cases, the tumours were discovered incidentally. The correct clinical diagnosis was made pre-operatively in a single case. By contrast, a diagnosis of RCC or other malignant tumour was proffered in eight cases. Pathologically, the maximum dimension of the seven excised tumours, in whom such information was recorded, ranged from 3.5 cm to 12 cm with a median of 7 cm. Spontaneous haemorrhage in the tumour was noted in three cases, all greater than 4.5 cm in maximum dimension. CONCLUSIONS: These data confirm that AML is uncommon at the University Hospital of the West Indies. There was an overwhelming female preponderance and patients presented, most commonly, in the 3rd to 4th decades. Tuberous sclerosis was identified in a solitary case. In this series, symptomatic lesions were > 4.5 cm in maximum dimension and haemorrhage complicated three cases. Most cases were incorrectly diagnosed preoperatively.
