[Management of patients with non-functioning gastroentero-pancreatic neuroendocrine tumours]. / Management di un paziente portatore di neoplasia neuroendocrina non fiunzionante del tratto gastro-entero-pancreatico (GEP).

The Authors examine the feasibility of diagnosing non-functioning gastroentero-pancreatic neuroendocrine tumours preoperatively or intraoperatively, with particular reference to laboratory examinations and octreoscan scintigraphy, which are capable of conditioning the surgical treatment and subsequent follow-up. Of the 4 cases reported here: three presented multiple intestinal localizations, and in only one case the origin of the primitive carcinoma was undefined. The suspicion of a non-functioning neuroendocrine tumour must be considered when yellowish or ochre-coloured intestinal lesions are found intraoperatively. Determination of specific markers and octreoscan scintigraphy must be performed without awaiting histological confirmation. Surgery plays a fundamental role in the debulking of these carcinomas. However, medical therapy with the aid of specific laboratory examinations and octreoscan scintigraphy may improve the long-term survival.

Prognostic value of extracapsular extension of axillary lymph node metastases in T1 to T3 breast cancer.

BACKGROUND: The importance of extracapsular extension (ECE) of axillary metastases as a risk factor for either local or distant recurrence and poorer survival in breast cancer has been suggested, but its prognostic value has not been uniformly confirmed. METHODS: From a prospective database including 1142 breast cancer patients operated on at the Department of General Surgery and Surgical Oncology of the University of Siena, we selected 376 cases with pT1 to pT3 node-positive breast cancer. The prognostic significance of ECE of axillary metastases was evaluated with respect to disease-free survival, overall survival, and the patterns of disease recurrence. Such prognostic significance was then compared with that of other clinical and pathologic factors. RESULTS: With a median follow-up of 103 months, factors with independent prognostic value for disease-free survival by multivariate analysis included absence of estrogen receptors (P < .0005), pN category (P < .01), presence of lymphovascular invasion (LVI; P < .005), and ECE (P < .0001). An independent negative prognostic effect on overall survival was observed for absence of estrogen and progesterone receptors (P < .05), pN category (P < .05), and presence of LVI (P < .005) and ECE (P < .0001). The presence of ECE was significantly related to an increased risk of regional (13.4% vs. 6.6%; P = .037) and distant (43% vs. 16.2%; P < .001) recurrences. CONCLUSIONS: ECE demonstrated a stronger statistical significance in predicting prognosis than the pN category and was also related to an increased risk of distant recurrences. We suggest that the decision on adjuvant therapy should consider the presence of ECE of axillary metastases and peritumoral LVI as indicators of high biological aggressiveness.

[Preoperative radio-chemotherapy in the treatment of locally advanced rectal cancer]. / Radio-chemioterapia preoperatoria nel trattamento del carcinoma del retto localmente avanzato.

Rectal cancer is characterised by a substantial incidence of recurrences despite radical surgical treatment. The combination of preoperative radio- and chemotherapy has afforded functional and prognostic advantages through the prospect it offers of performing a greater number of conservative operations and the enhanced control of locoregional recurrences it allows. In our institute we treated 27 patients with locally advanced rectal cancer over the period from January 1997 to December 2002. All 27 patients underwent preoperative radiochemotherapy (45 Gy on the pelvis and 5-fluorouracil administered on the first and last 5 days of radiotherapy). The patients were then submitted to surgery consisting in 12 abdomino-perineal resections of the rectum, 14 anterior rectal resections and 1 Hartmann's resection. Tumour regression was complete in 22.22% of cases and minimal in 14.81%; 50% reduction was achieved in 22.22% and 50-80% reduction in 40-70% of cases. The toxicity was 14.91%. The incidence of local failure was 3.7% with a follow-up of 52 months. In this series, preoperative radio-chemotherapy proved to be a powerful means of downstaging the tumours and of controlling local failure.
