Non functioning endocrine pancreatic tumors (NF-PETs) have absent or low hormone secretion without symptoms and constitue ~60% of PETs. At diagnosis more than 50% of patients have liver metastases and almost 40% are not candidates for radical surgery because of either locally advanced disease or unresectable metastases. We described the case of a 47-year-old woman with a pancreatic carcinoma with secondarism in the liver not suitable for radical surgery. Histological test of liver metastases showed positivity for endocrine well-differentiated non functioning carcinoma expressing receptors for somatostatin with very low proliferation index (Ki67 < 2%). After this diagnosis she started a specific treatment with octreotide analogues which achieved durable stabilization of the disease.

Aims and background The epidermal growth factor receptor (EGFR) is a member of a family of cell membrane receptors that use tyrosine kinase activity as the signal transduction mechanism. It is commonly expressed or overexpressed by many solid tumors and correlates with disease progression and a poor clinical prognosis. Increased EGFR expression might therefore be a strong prognostic feature in multiple tumor types, and inhibition of its cellular actions may have substantial therapeutic benefit. The aim of this study was to estimate the EGFR serum concentration for potential use as a biological marker of brain cancer to predict prognosis and follow-up after treatment. Methods and study design Serum samples obtained from 50 healthy individuals and 65 brain cancer patients (35 glioblastoma multiforme and 30 anaplastic astrocytomas) were collected before and after treatment and assayed for EGFR extracellular domain serum concentrations by a sandwich ELISA. Results EGFR was elevated in 47 of 65 brain cancer patients, with mean serum values of 84 ± 18 ng/ml, compared with that of healthy controls (43.6 ± 11 ng/ml, P = 0.001). There was a significant difference in the mean serum levels of EGFR between glioblastoma multiforme patients (96.2 ± 12 ng/ml) and anaplastic astrocytoma patients (71.6 ± 18 ng/ml, P = 0.04). Sixty brain cancer patients underwent surgery; EGFR serum levels did not show significant differences from those observed before surgery. For all patients, median overall survival was 13 months (anaplastic astrocytoma, 18 months; glioblastoma multiforme, 12.5 months). In 47 patients with high EGFR serum levels, overall survival was reduced (P = 0. 01), with a median survival time corresponding to 11.5 months (anaplastic astrocytoma, 14.5 months; glioblastoma multiforme, 10.5 months). Conclusions Although a prospective study with large sample size is warranted, serum EGFR extracellular domain may be potentially useful as a biological marker of gliomas for prediction of prognosis and follow-up after treatment.

Aims and Background Rarely are conclusions from clinical trials summarized in international consensus conferences and promptly transferred to patient care. The adjuvant therapy for colorectal cancer used in daily clinical practice in Italy is described and compared with the recommendations of the 1990 NIH Consensus Conference. Patients and Methods We audited prescriptions of adjuvant systemic therapies for Italian colorectal cancer patients in 82 centers during a fixed one-week period. Results Among 434 patients receiving adjuvant chemotherapy there were 139 (42.5%) colon cancer patients with N- and 169 (51.7%) with N+ regional nodal involvement. Treatment at academic centers, a young age, T4 and a low total number of lymph nodes removed at surgery were the factors potentially justifying the decision for adjuvant chemotherapy in stage II colon cancer patients. The most common chemotherapy used was a bolus of 5-fluorouracil/folinic acid for 6 months (75.8%). Adjuvant radiotherapy was not administered to 37 (38.5%) of 96 patients with stage II and III rectal cancer. Conclusions The study shows that a substantial proportion of patients on adjuvant treatment at a certain time point in a large enough sample of Italian centers are stage II (potential over-treatment) and that an under-treatment of stage II and III rectal cancer patients (lack of radiotherapy) occurs too often in daily clinical practice in this country.

This case study regards the murder of a Tunisian national residing in a small town in southern Italy who was murdered by fellow Tunisian citizen, also living in Italy. The victim was found hogtied and hanged by a cord that was suspended from an iron staff situated between two concrete electrical poles. This method of killing is known as "incaprettemento". It is an unusual type of strangulation whereby a rope is passed around the victim's wrists, ankles, and throat causing suffocation. This results in a very slow and painful death. Typically, it is a method employed by Italian organized crime groups, but it has also been used in the execution of war crimes. This means of killing is meant to impart a particularly degrading and humiliating revenge on the victim. It may also serve as sign of intimidation and a warning to others. There is very little written about incaprettamento in the literature, but it has, nonetheless, important psychological, anthropological, and cultural implications in the field of criminology. The perpetrator underwent psychodiagnostic evaluations, and was ultimately deemed fit to stand trial. Keywords: Incaprettamento, Ligature strangulation, Hog-tie, intra-ethnic homicide.

There are few cases described in the world literature reporting an association of thymoma (with myasthenia gravis or not) with hyperparathyroidism. In these cases the hyperparathyroidism was due to the presence of an adenoma or hyperplasic parathyroid tissue either in the cervical region or in an ectopic intrathymic location.(12345) In other cases the syndrome of hypercalcemia was due to the secretion of parathyroid-related protein (PTHRP) (6) or parathyroid hormone (PTH) (7) by the thymoma itself. We report the first case, at the best of our knowledge, of a wide invasive malignant thymoma (type B3), associated with myasthenia gravis and hyperparathyroidism caused by parathyroid adenoma.

Aims and Background The necessity of an antiemetic prophylaxis in patients treated with chemotherapy of low emetogenic potential, such as 5-fluorouracil ± folinic acid fractionated over several consecutive days, is controversial. The aim of the study was to evaluate the therapeutic behavior of oncologists on this issue. Methods All consecutive in and out patients who started chemotherapy in 33 Italian oncological departments from June 24 to July 6, 1996, were studied. The antiemetic prescription pattern and its effectiveness, in patients submitted to 5-fluorouracil ± folinic acid were evaluated. Results Of the 1956 patients submitted to cancer chemotherapy, 259 patients received 5-fluorouracil ± folinic acid. Of these, 186 patients were treated for 5 consecutive days, 47 for 4 days, 20 for 3 days and 6 for 2 days. A total of 219 (84.5%) received an antiemetic prophylaxis: 43.4% a 5-HT3 antagonist ± steroids, 37.5% an antidopaminergic drug, 10.9% a steroid ± antidopaminergic drug, and 8.2% other drugs. Only 40 patients (15.5%) did not receive an antiemetic prophylaxis. Overall complete protection from vomiting/nausea was 225/259 (86.9%)/163/259 (62.9%). The complete protection from vomiting/nausea during the 5 days in the 186 patients was not significantly different among patients receiving or not an antiemetic prophylaxis (88.1%/64.9% vs 88.9%/55.6%). At unifactorial analysis, the previous experience of vomiting/nausea caused by chemotherapy was found to be a significant prognostic factor. In fact, overall complete protection from vomiting/nausea was significantly inferior in patients who had previous experience of vomiting/nausea (65.1%/35.0%) with respect to those who did not (91.2%/75.4%, P < 0.001/> 0.001, respectively). Conclusions. The study showed that in clinical practice patients submitted to 5-fluorouracil ± folinic acid obtained a similar high protection from vomiting and nausea regardless of whether or not antiemetic prophylaxis was given. It would be therefore reasonable not to treat patients undergoing such chemotherapy, whereas patients with previous experience of vomiting/nausea caused by chemotherapy should be given an antiemetic prophylaxis.

15528 Background: The neuroendocrine (NE) cells in prostate cancer are indistinguishable from non-NE cancer cells morphologically and are usually detected by immunohistochemical study for NE markers. We analyzed the expression of Chromogranin A (Chr A) in malignant prostate tissue as prognostic factor for docetaxel response in metastatic HRPC. Methods: From January 2003 to December 2006, 40 patients with metastatic HRPC received a median of 12 cycles (range 2–18) of Docetaxel 75 mg/mq every 21 days and 5 mg of prednisone twice daily as initial therapy. Tissue blocks from primary prostate cancer tissues were obtained and immunostaining for Chr A was performed. The median age was 70 years (range 46–82); median baseline PSA: 310 ng/ml (range 0.15–700); median ECOG Performance Status: 1 (range 0- 2). PSA level was measured every 4 weeks and the treatment was considered effective if a rate of PSA-decline > 50% from baseline was found. TTP was the preliminary end point. Results: Response to Docetaxel was assessed at every 3 cycles of treatment. The Chr A expression was found in 19/40 patients with Gleason = 7, PSA < 20, bone and soft tissue metastasis; 10 of them showed PR (decrease in PSA < 50%), 4 SD and TTP was 9.2 months. Moreover they received second line chemotherapy without significant efficacy. 5/19 patients with Chr A expression showed PD, the PSA level was not correlated with clinical outcome, TTP was 5 months and were chemoresistant to different line treatment. Besides, Chr A was not detected in 21/40 patients with Gleason = 7, PSA > 20 and bone metastasis; 10 of them showed CR (PSA normalized) and 11 PR, TTP was 20 months. Conclusions: NE differentiation do not constituite a different histopathological category of prostate cancer but the NE phenotype can be correlated with poorly differentiated adenocarcinoma. NE differentiation can be considered a factor that influences prognosis and treatment in advanced prostate cancer; cases with Chr A expression did not benefit from Docetaxel and had poor prognosis. These preliminary data indicate that initial therapeutic approach should be different according to Chr A expression. No significant financial relationships to disclose.

The NBT-test was performed in 54 patients with Hodgkin and non-Hodgkin lymphoma showing no bacterial infection exept for one case. 18 patients presented, at onset of the disease, a number of neutrophilic NBT-reducing granulocytes at pathological levels (greater than 12%). In order to evaluate the influence of cytostatic drugs on NBT-test serial blood samples were taken during polychemotherapy in 17 patients with lymphoma. In our experience, cytostatics (COPP) do not necessarily lessen NBT-reducing activity of granulocytes. The results suggest that the NBT in malignant lymphomas could not be used as an indication of bacterial infection.
