Emergency surgery for recurrent intraabdominal cancer

Recurrent abdominal cancer can manifest in many ways but there are certain situations that are a great challenge to clinicians. Emergency presentation is one such situation. Surgeons are faced with a therapeutic dilemma that on the one hand most of these patients have a limited life expectancy, and on the other surgical procedures are unavoidable. We reviewed our experience of recurrent abdominal cancers presenting with acute abdominal symptoms requiring emergency

Unbalanced Immune System: Immunodeficiencies and Autoimmunity

Increased risk of developing autoimmune manifestations has been identified in different primary immunodeficiencies (PIDs). In such conditions, autoimmunity and immune deficiency represent intertwined phenomena that reflect inadequate immune function. Autoimmunity in PIDs may be caused by different mechanisms, including defects of tolerance to self-antigens and persistent stimulation as a result of the inability to eradicate antigens. This general immune dysregulation leads to compensatory and exaggerated chronic inflammatory responses that lead to tissue damage and autoimmunity. Each PID may be characterized by distinct, peculiar autoimmune manifestations. Moreover, different pathogenetic mechanisms may underlie autoimmunity in PID. In this review, the main autoimmune manifestations observed in different PID, including humoral immunodeficiencies, combined immunodeficiencies, and syndromes with immunodeficiencies, are summarized. When possible, the pathogenetic mechanism underlying autoimmunity in a specific PID has been explained

\u201cWeekly docetaxel and gemcitabine as first line treatment for metastatic breast cancer: results of a multicenter phase II study\u201d

Objectives: We conducted a multicenter phase II study to evaluate the clinical effi cacy, toxicity, and dose intensity of a new weekly schedule of docetaxel and gemcitabine as fi rst-line treatment of metastatic breast cancer patients. Methods: We enrolled 58 patients, 52% of whom had received a previous anthracycline-containing chemotherapy. The treatment schedule was: docetaxel 35 mg/m 2 and gemcitabine 800 mg/m 2 i.v. on days 1, 8,15 every 28 days. Results: All patients were assessable for toxicity and 56 for effi cacy. Overall response rate was 64.3% with 16.1% of complete responses and 48.2% of partial responses. Median survival was 22.10 months (95% CI: 15.53\u201328.67) and median time to tumor progression was 13.6 months (95% CI: 10.71\u201316.49). The most common hematological toxicity was neutropenia (no febrile neutropenia), which occurred in 28 patients (48.3%) but grade 3\u20134 in only 8 patients (14%). Alopecia, the most common nonhematological toxicity, occurred in 20 (34.5%) patients, but only 5 patients (8.6%) experienced grade 3 alopecia. Conclusion: The activity of docetaxel and gemcitabine in metastatic breast cancer is confirmed. The promising results of the employed schedule,in agreement with other published studies, need to be further confirmed within a phase III study

Efficacy of the combination of cisplatin with either gemcitabine and vinorelbine or gemcitabine and paclitaxel in the treatment of locally advanced or metastatic non-small-cell lung cancer: a phase III randomised trial of the Southern Italy Cooperative Oncology Group (SICOG 0101)

Triplet regimens were occasionally reported to produce a higher response rate (RR) than doublets in locally advanced or metastatic non-small-cell lung cancer (NSCLC). This trial was conducted to assess (i) whether the addition of cisplatin (CDDP) to either gemcitabine (GEM) and vinorelbine (VNR) or GEM and paclitaxel (PTX) significantly prolongs overall survival (OS) and (ii) to compare the toxicity of PTX-containing and VNR-containing combinations

Hepatoid carcinoma colliding with a liposarcoma of the left colon serosa presenting as an abdominal mass

BACKGROUND: Hepatoid adenocarcinoma (HAC) is a peculiar type of extrahepatic adenocarcinoma generally characterized by adenocarcinomatous and hepatocellular carcinoma (HCC)-like foci. Stomach is the most frequent site where hepatoid adenocarcinoma occurs, although it has been described in many other organs. On the other side, liposarcoma is a rare, malignant tumor that develops from fat cells. CASE PRESENTATION: We describe here a case of hepatoid carcinoma in collision with a liposarcoma of the left colon serosa in a 71-year-old man. It presented as an abdominal mass involving several organs, falsely mimicking metastatic colonic adenocarcinoma. Recognition of this entity was evident on microscopic evaluation following surgery. The patient had an objective response following liposomal antracycline chemotherapy, with a 3-year overall survival. CONCLUSION: To our knowledge, this is the first case of a hepatoid tumor colliding with a liposarcoma of the left colon serosa reported to date

Postoperative Delirium after elective and emergency surgery: analysis and checking of risk factors. A study protocol

BACKGROUND: Delirum is common in hospitalized elderly patients and may be associated with increased morbidity, length of stay and patient care costs. Delirium (acute confusional state) is defined as an acute disorder of attention and cognition. In elderly patients, delirium is often an early indicator of patho-physiological disturbances. Despite landmark studies dating back to the 1940s, the pathogenesis of Delirium remains poorly understood. Early investigators noted that Delirium was characterized by global cortical dysfunction that was associated predominantly with specific electroencephalographic changes. It's important to understand the risk factors and incidence of Delirium. Some of the risk factors are already identified in literature and can be summarized in the word "VINDICATE" which stands for: Vascular, Infections, Nutrition, Drugs, Injury, Cardiac, Autoimmune, Tumors, Endocrine. Aims of this study are: to re-evaluate the above mentioned clinical risk factors, adding some others selected from literature, and to test, as risk factors, a pattern of some genes associated to cognitive dysfunction and inflammation possibly related to postoperative Delirium. DESIGN: All patients admitted to our Emergency Unit who are meet our inclusion/exclusion criteria will be recruited. The arising of postoperative Delirium will select incidentally two groups (Delirium/non Delirium) and the forward analysis of correlate risk factors will be performed. As in a typical observational case/control study we will consider all the exposure factors to which our population are submitted towards the outcome (presence of Delirium). Our exposures are the following: ASA, Pain (SVS; VAS), Blood gas analysis (pH; Hb; pO2; pCO2), Residence pharmacological therapy (BDZ; hypnotics; narcotic drugs; alcohol; nitrous derivates), Body temperature, Arterial pressure, Heart frequency, Breath frequency, Na, K, Creatinin, Glicemia, Albumin, Hct, White blood cells, Glasgow Coma Scale (GCS), Cognitive state (SPMSQ), Functional state (ADL and IADL), Psychological Distress (HADS), Cumulative Illness Rating Scale (CIRS), Hypotension (classified in: light; moderate and severe and duration), Blood loss (classified in: < 2 lt and > 2 lt), Blood transfusions (< 2 lt and > 2 lt), Quantity of red cells and plasma transfusions, Visual VAS / SVS (timing: I-II-III post-operative day), Red cells and Plasma transfusions, Blood count evaluation and Saturation (O(2)%), Postoperative analgesia (Emilia-Romagna protocol), Presence of malignant tumoral disease, APACHE Score II. Moreover the presence of some relevant genetic polymorphisms will be studied in different genes such as IL-6, IL-10, TNF-alpha, and IL-1 cluster

Small bowel tumours in emergency surgery: Specificity of clinical presentation

Background: Despite advances in diagnostic modalities, small bowel tumours are notoriously difficult to diagnose and are often advanced at the time of definitive treatment. These malignancies can cause insidious abdominal pain and weight loss, or create surgical emergencies including haemorrhage, obstruction or perforation. The aim of the present study was to describe the clinical presentation, diagnostic work-up, surgical therapy and short-term outcome of 34 patients with primary and secondary small bowel tumours submitted for surgical procedures in an emergency setting and to look for a correlation between clinical presentation and the type of tumours. Methods: From 1995 to 2005, 34 consecutive surgical cases of small bowel tumours were treated at the Department of Emergency Surgery of St Orsola-Malpighi University Hospital, Bologna, Italy. Clinical and radiological charts of these patients were reviewed retrospectively from the department database. Results: All patients presented as surgical emergencies: intestinal obstruction was the most common clinical presentation (15 cases), followed by perforation (11 cases) and gastrointestinal bleeding (eight cases). Lymphoma was the most frequent histologic type (nine patients), followed by stromal tumours (eight patients), carcinoids (seven patients), adenocarcinoma (seven patients) and metastasis (three patients). Of the nine patients with lymphoma, eight were perforated, all patients with stromal tumours had bleeding, and all carcinoids patients had bowel obstruction. There were two patients with melanoma metastasis, both had bowel intussusception. Resection of the neoplasm was carried out in 32 patients and two patients were deemed unresectable and received a palliative procedure. Conclusions: The present study shows that there is a correlation between small bowel tumours and clinical emergency presentation: gastrointestinal stromal tumours (GIST) mostly bleed; carcinoids make an obstruction; lymphomas cause a perforation; and melanoma metastasis causes intussusception
