CEA and CA19.9 as early predictors of progression in advanced/metastatic colorectal cancer patients receiving oxaliplatin-based chemotherapy and bevacizumab.

We evaluated the changes of the tumor markers CEA and CA19.9 as early predictors of progression in metastatic colorectal cancer (mCRC) patients participating in a clinical study and receiving chemotherapy and bevacizumab (Bev). Seventy-two patients had high baseline CEA or CA19.9 serum levels. By ROC analyses, the areas under the curves were 0.83 for variable CEA cutoff values for distinguishing progressive disease (PD) versus stable disease (SD)/partial remission (PR)/complete remission (CR), and 0.80 for variable CA19.9 cutoff values for distinguishing PD versus SD/PR/CR. Rises in CEA and CA19.9 may early signal the occurrence of progression in mCRC patients receiving chemotherapy and Bev.

Bevacizumab and weekly docetaxel in patients with metastatic castrate-resistant prostate cancer previously exposed to docetaxel.

Background. The aim of this paper was to evaluate the activity and tolerability of docetaxel (D) and bevacizumab (Bev) in patients with metastatic castrate-resistant prostate cancer (CRPC) previously exposed to D. Methods. Treatment consisted of D 30 mg/m(2) i.v. for four consecutive weekly administrations followed by a 2-week rest interval, in addition to Bev 5 mg/kg i.v. every 2 weeks. Results. Forty-three patients were enrolled: a PSA response was observed in 27 patients (62.7%, 95% CI: 0.41 to 0.91), and a palliative response was achieved in 31 patients (72.1%, 95%CI: 0.48 to 1.02). After a median followup of 11.3 months, only five patients had died. The regimen was generally well tolerated. Conclusion. Weekly D + biweekly Bev seems to be an effective and well-tolerated treatment option for patients with metastatic CRPC previously exposed to D-based chemotherapy.

[Acute abdomen by anisakiasis and globalization]. / Addome acuto da anisakiasi e globalizzazione.

OBJECTIVES: The AA report a case of a patient with acute abdomen caused by intestinal Anisakiasis, a fish-transmitted infection that results from ingestion of raw or improperly cooked fish contaminated by live larvae of Anisakis Simplex, a round worm from the order of Ascaridida. MATERIAL AND METHODS: A 33-year-old man, presented to the emergency room with severe upper abdominal pain, nausea and vomiting, without fever. The patient revealed that he had eaten pickled anchovies a few days before. RESULTS: On the exploratory laparotomy an edematous and stenotic tract of 15 cm of jejunum was found, and a segmental resection was performed. Histologically, the resected jejunum showed a conspicuous and diffuse inflammatory infiltration, predominantly made up of eosinophil granulocytes, numerous mucosal erosions and the presence in the submucosa of sections of parasites which were identified as Anisakis Simplex larvae. DISCUSSION: The ingestion of fish contaminated by Anisakis larva is often followed by the appearance of systemic or gastrointestinal symptoms due respectively to the direct larva localization and the allergic reaction to some parasite components. Diagnosis is made frequently difficult by clinical manifestations that could mimic symptoms of other diseases more common in Italy. CONCLUSIONS: Globalization has made Anisakiasis a more and more frequent disease worldwide, as increased mixture of different cultures and international travelling has allowed the spreading of risky feeding habits. That's why Anisakiasis should be considered in differential diagnosis of intestinal obstruction in patients with positive anamnesis for suspiciously cooked or conserved seafood eating.

[Intestinal occlusion by ileal carcinoid]. / Occlusione intestinale da carcinoide ileale.

OBJECTIVE: Ileal carcinoids diagnosis, generally, is late because patients have aspecific symptoms. MATERIAL OF STUDY: The two cases described presented for a long time peristaltic abdominal pains, vomit episodes and reduction of weight, with negativity of radiologic reports. The first diagnosis was adhesion syndrome produced by previous abdominal surgical operation; just emergency surgical operation executed for intestinal occlusion noticed carcinoids, located into the distal ileum, which infiltrated muscular wall and interested regional lymph nodes. RESULTS: Ileal carcinoids diagnosis, generally, takes place during emergency laparotomy for intestinal occlusion which is the most frequent complication of this tumor. At the moment of diagnosis the tumor presents an advanced stage of evolution. DISCUSSION: Ileal carcinoids behave malignant because of their biologic aggressiveness and because of at the moment of diagnosis they present an advanced stage of evolution. Symptomatology is aspecific, just a carcinoid syndrome could addressed clinical diagnosis, but this is an rare event and however it needs of liver metastases to appear. In case there is an clinical suspect scintigraphy with Octreoscan can locate tumor and metastases. CONCLUSIONS: Surgical treatment of ileal carcinoids is based on large resections en bloc. Ileal carcinoids survival to 5 years is estimated inferior to 60% after surgical treatment.

Folinic acid, 5-fluorouracil and etoposide after curative resection for gastric cancer.

BACKGROUND/AIMS: The aim of this study was to evaluate the survival benefit of adjuvant chemotherapy with etoposide, leucovorin and 5-fluorouracil (ELF) in gastric cancer patients undergoing previous surgery with a curative intent. METHODOLOGY: The clinical outcome of 49 patients with resected gastric cancer treated with adjuvant chemotherapy was compared with that of 85 surgically treated historical controls who did not receive any adjuvant treatment. The chemotherapy regimen consisted of six cycles of daily 1-hour intravenous infusions of folinic acid 100 mg/m2 and 5-FU 400 mg/ m2, and a 2-hour infusion of etoposide 100 mg/m2, for three days every 28 days. RESULTS: The 5-year relapse-free survival was 32% in the adjuvant arm and 27% in the control arm (p = 0.6). At the last follow-up, there were 32 deaths in the adjuvant arm and 60 in the control arm. The median duration of survival was respectively 23 and 19 months, and the 5-year survival rates were 34% and 29% (p = 0.4). The chemotherapy was well tolerated. CONCLUSIONS: Our data suggest that ELF adjuvant treatment is a safe and well tolerable combination chemotherapy in patients with resected gastric cancer, but it does not seem to improve prognosis in comparison with historical controls.

[Necrotizing enterocolitis in the preterm infant: etiopathogenic considerations]. / Enterocolite necrotizzante nel neonato pretermine: considerazioni eziopatogenetiche.

Necrotizing enterocolitis (NE) represents the most frequent gastrointestinal emergency encountered in neonatal intensive care units. This necrotic-inflammatory bowel disease affects primarily premature patients and it is recorded as an important cause of neonatal morbidity and mortality. The NE aetiology seems to be multifactorial: prematurity, enteral feeding, hypoxia and micro-organisms toxicity are registered as the most important risk factors, able to trigger the phlogistic and necrotic way at the basis of necrotizing enterocolitis. Despite the NE first report was in the past century, the correct pathogenic sequence of this neonatal disease is still hypothetical.

Adjuvant epirubicin with or without Ifosfamide for adult soft-tissue sarcoma.

This randomized study compared the efficacy of epirubicin-based adjuvant chemotherapy on the disease-free interval (DFI) and overall survival of patients with high-risk soft-tissue sarcomas. After curative surgery, 43 of the 88 enrolled patients were assigned to surgery with or without radiotherapy and 45 to surgery plus chemotherapy (26 epirubicin, 19 epirubicin + ifosfamide) with or without radiotherapy. The trial closed prematurely because of poor patient accrual. There was a statistical significant difference in the 5-year disease-free survival of the patients receiving adjuvant chemotherapy with or without radiotherapy (69%) and that of those treated with surgery with or without radiotherapy (44%) ( p= 0.01). The 5-year survival of the patients treated with adjuvant chemotherapy with or without radiotherapy was 72% as against 47% of those treated with surgery with or without radiotherapy ( p= 0.06). The power of the study was 0.65 for both the DFI and overall survival. The results of the study suggest a possible advantage of epirubicin-based adjuvant chemotherapy in patients with soft-tissue sarcoma at high risk of relapse.

[Reflux-like dyspepsia in obese patients]. / La dispepsia simil-reflussiva nel paziente obeso.

The aim of this study was to assess, with a specially prepared questionnaire, the prevalence of reflux-like dyspepsia in a population of 40 patients morbidly obese, Body Mass Index (BMI) 46.2+/- 1.7 kg/m2, comparing the results with those deriving from the analysis of 20 healthy volunteers (BMI 20.9+/-1.7 kg/m2). The prevalence of esophageal symptoms in all obese patients was 45%, versus 15% in controls. There was a significant direct correlation between obesity and reflux-like dyspepsia (p<0.05). Patients who are morbidly overweight should be encouraged to lose weight, as the very first step in fighting Gastro-Esophageal Reflux Disease.
