Adenocarcinoma of the appendix with extra-appendicular spread: Clinico-surgical and histologic analysis of 27 cases.
2017
Abstract Background and objectives Appendiceal neoplasms with extra-appendiceal spread may show different clinical patterns with pseudomyxoma peritonei (PMP) being one of them. We analyse the results in a series of patients treated in our centre. Material and methods Retrospective study of patients operated on for appendiceal peritoneal carcinomatosis from January 2012 to May 2015. Results Twenty-seven consecutive patients were included. Median age 63 years (26–73); 14 were men. Peritoneal carcinomatosis index = 16 ± 8 (3–31). The suspected preoperative origins were appendix in 23, ovary in 3 and urothelial in one. Postoperative mortality in 2 patients (7.4%). The remaining 36% presented mo…
Atypical Pleomorphic Extraosseous Ewing Tumor/Peripheral Primitive Neuroectodermal Tumor with Unusual Phenotypic/Genotypic Profile
2002
A pleomorphic undifferentiated tumor primarily located in the retroperitoneum with a phenotype compatible with an extraosseous Ewing tumor/peripheral primitive neuroectodermal tumor (ET/pPNET) pattern and unusual molecular features is described. Immunohistochemically, HBA-71 (CD99/mic2) and several neural markers were intensively expressed together with scattered cells expressing carcinoembryonic antigen (CEA). Short-term culture showed biphasic neuroblastic and epithelioid cell populations, with the latter expressing germ cell markers (CEA, alpha-fetoprotein, and the beta-subunit of chorionic gonadotrophin). Conventional cytogenetics displayed several chromosomic rearrangements, especially…
Safety and Feasibility of a New Minimally Invasive Diagnostic Laparoscopy Technique
1998
Background and Study Aims: Laparoscopy combined with guided liver biopsy offers many advantages in the diagnosis and staging of chronic liver diseases and is superior to other diagnostic procedures. We developed a new minilaparoscopic technique and evaluated the utility of this minimally invasive laparoscopic system in the first 320 patients who underwent diagnostic assessment for liver disease or peritoneal carcinosis. Patients and Methods: Between July 1996 and February 1998, minilaparoscopy, with analgesia and sedation was carried out in 320 patients. It was done using a 1.9-mm optical instrument, which was inserted through the same 2.75-mm trocar as the Veress needle used for inflating …
Systemic chemotherapy and pressurized intraperitoneal aerosol chemotherapy (PIPAC): A bidirectional approach for gastric cancer peritoneal metastasis
2019
Abstract Background Few patients affected by gastric cancer peritoneal metastasis (GCPM) are offered locoregional treatment, despite several proof-of-efficacy trials. Pressurized intraperitoneal aerosol chemotherapy (PIPAC) has emerged in recent years as a promising tool to control peritoneal carcinomatosis. The combination of PIPAC with systemic chemotherapy may offer a greater clinical benefit than standard treatment alone. Methods A single-center cohort of 28 consecutive patients affected by GCPM was scheduled for bidirectional treatment, comprising PIPAC and systemic chemotherapy, from September 2017 to September 2019. Data recorded included safety, efficacy and survival outcomes. Ascit…
The Value of Sonography and Lymphography in the Detection of Retroperitoneal Metastases in Testicular Tumors
1979
Lymphography has led to falsely negative or falsely positive diagnoses in 10 to 45 per cent of the cases of testicular tumor metastases reported in the literature. In our comparative study of lymphography and sonography in the preoperative staging of 29 malignant testicular tumors lymphography was accurate in 58.5 per cent of the cases, while sonography had an accuracy rate of 82.5 per cent. Sonography was superior to lymphography in the evaluation of hilar lymph node metastases and their extent, as well as for routine checkups after lymphadenectomy or irradiation.
Phase 2 Trial of Docetaxel, Gemcitabine, and Oxaliplatin Combination Chemotherapy in Platinum- and Paclitaxel-Pretreated Epithelial Ovarian Cancer
2009
Background: This phase 2 trial was designed to evaluate the efficacy and toxicity of a combination of docetaxel, gemcitabine, and oxaliplatin for platinum- and paclitaxel-pretreated epithelial ovarian cancer. Patients and Methods: Heavily pretreated patients (N = 30; median age, 61 years) received docetaxel, 55 mg/m2; gemcitabine, 500 mg/m2 (day 1); and oxaliplatin, 70 mg/m2 (day 2) biweekly. Twelve patients had platinum-sensitive disease, and 18 patients had platinum-resistant disease. Results: Median follow-up was 18.6 months. No differences in patient characteristics were observed between patients with carboplatinum-sensitive and carboplatinum-resistant disease. In patients with carbopla…
Influence of Intraperitoneal Dissemination Assessed by Laparoscopy on Prognosis of Advanced Ovarian Cancer: An Exploratory Analysis of a Single-Insti…
2014
Purpose: The aim of this study was to investigate whether preoperative laparoscopic evaluation of the dissemination of disease may have an independent impact on survival in advanced epithelial ovarian cancer (AEOC).Methods: All AEOC women were submitted to staging laparoscopy before receiving primary debulking surgery (PDS) or neoadjuvant chemotherapy (NACT). All study women received a laparoscopic score (predictive index value [PIV]) and were stratified into three groups based on volume of disease: high tumor load (HTL) for PIV ≥8, intermediate tumor load (ITL) for PIV equal to 6 and 4, and low tumor load (LTL) for PIV 1 cm in 15 cases (9.1 %). When stratifying the whole population accordi…
Phase II trial of docetaxel and carboplatin in recurrent platinum-sensitive ovarian, peritoneal and tubal cancer
2007
Abstract Objective. Docetaxel and carboplatin are active in relapsed ovarian, peritoneal and tubal cancer. Recently, two prospective-randomized trials showed an advantage of carboplatin combination regimen with paclitaxel or gemcitabine over carboplatinum alone in platinum-sensitive cases. The question on the most effective combination with the best tolerable side effects still needs to be answered. Methods. Eligible patients had recurrent ovarian, peritoneal or tubal cancer (platinum-free interval >6 months), performance status 0–2 and normal bone marrow, renal and hepatic function. 25 patients (age 18–75 years) were enrolled into this phase II trial. Patients with debulking operation of r…
Ovarian Endometrioid-like Yolk Sac Tumor Treated by Surgery Alone, with Recurrence at 12 Years
1999
Abstract We describe the case of a stage Ia endometrioid-like yolk sac tumor (YST) of the ovary, which was originally misdiagnosed as a malignant struma ovarii and not treated with adjuvant chemotherapy. After 12 years, a contralateral dermoid cyst was excised along with a small omental nodule of partially necrotic and calcified endometrioid-like YST. No tumor was detected in several other biopsy specimens, and a peritoneal lavage was negative for tumor cells. Since there was no evidence of remaining tumor and the serum α-fetoprotein (AFP) level was normal after the second operation, the patient was followed. Serial serum AFP levels remained normal for 4 months. At a second-look laparotomy …
Pain Mechanisms in Peritoneal Diseases Might Be Partially Regulated by Estrogen
2017
To identify factors influencing the differential pain pathogenesis in peritoneal endometriosis (pEM) and peritoneal carcinomatosis in ovarian cancer (pOC), we undertook an experimental study. Tissue samples of 18 patients with pEM, 15 patients with pOC, and 15 unaffected peritoneums as controls were collected during laparoscopy or laparotomy. Immunohistochemical stainings were conducted to identify nerve fibers and neurotrophins in the tissue samples. Additionally, 23 pEM fluids, 25 pOC ascites fluids, and 20 peritoneal fluids of patients with myoma uteri as controls were collected. In these fluids, the expression of neurotrophins was evaluated. The effects of peritoneal fluids and ascites …
