Prognostic significance of intratumoural microvessel density (IMD) in resected pancreatic and ampullary cancers to standard histopathological variables and survival.

AIM: Angiogenesis is required for tumour growth. Its evaluation, by intratumoural microvessel density (IMD), has prognostic significance in many solid tumours. There is controversy regarding its use in pancreatic cancer and little is known about its role in ampullary tumours. The aim is to study IMD as a prognostic marker in resected ductal adenocarcinomas of head of pancreas and cancers of the ampullary region. METHODS: Forty-seven patients (23 pancreatic and 24 ampullary, mean age 62.0 years) surviving a potentially curative (R0/R1) resection were analysed. Paraffin-embedded sections of these tumours were immunohistochemically stained for CD-34 and IMD was determined (magnification x200). This was correlated with histopathological data and survival using Cox's multivariate analysis. RESULTS: Mean survival for the pancreatic cancer group was 18.4 months (SE=2.7) and 81.2 months (SE=9.9) for the ampullary cancer group. In the pancreatic cancer group, IMD was found to have independent prognostic significance to survival on multivariate analysis (P=0.002, Hazard Ratio (HR) 13.60) along with microscopic resection margin involvement (P=0.003, HR 15.18). For ampullary cancers, IMD was higher in those with lymph node metastasis (P=0.02, Mann-Whitney U -test). CONCLUSION: IMD in resected pancreatic cancers correlates with survival.

FILM (5-fluorouracil, ifosfamide, leucovorin and mitomycin C), an alternative chemotherapy regimen suitable for the treatment of advanced breast cancer in the 'out-patient' setting.

FILM, a combination of 5-fluorouracil (5-FU) 750 mg/m(2), ifosfamide 1 g/m(2), leucovorin 200 mg/m(2) and mitomycin C 6 mg/m(2) (alternate cycles), was administered to 24 chemo-naive patients with inoperable disease, locally advanced or metastatic. Up to 6 x 3-weekly cycles of FILM were administered on an out-patient basis. Responses included 8 patients in complete remission (CR) and 12 showing a partial response (PR) (83%). Following analysis of these results, the FILM regimen was introduced as a standard out-patient protocol at the North Middlesex Hospital, United Kingdom. A further 66 patients have been treated in this setting. Retrospective analysis of these data confirm the trial results and allow conclusions regarding tolerability, toxicity, duration of response and survival to be drawn from a total cohort of 90 patients. A total of 524 cycles have been administered. Nineteen cycles (4%) were delayed owing to slow recovery of white blood cells (WBC), but no dose reductions were necessary. Five blood transfusions were required for anaemia. The most frequent non-haematological toxicities included nausea, vomiting and fatigue. Of 80 patients treated for inoperable or locally advanced disease, 56 (70%) remain in remission, and 69 (86%) remain alive after 5 years.

Faecal incontinence after anal dilatation.

We have studied 10 patients with faecal incontinence occurring after anal dilatation. Abnormalities were found in the external and sphincter in clinical and manometric tests in five patients and in single fibre EMG tests in four patients. Internal anal sphincter function was impaired in eight patients. These findings have implications for prevention of faecal incontinence after this procedure.

Objectives of basic surgical training.

There are a range of skills to be learned in basic surgical training. These include communication and patient management, operating and other technical skills, and audit. Surgical tutors might use such a framework to facilitate education and assessment of their trainees.
