PURPOSE To evaluate the tolerance of peritonectomy procedures (PP) combined with intraperitoneal chemohyperthermia (IPCH) in patients with peritoneal carcinomatosis (PC), a phase II study was carried out from January 1998 to September 2001. PATIENTS AND METHODS Fifty-six patients (35 females, mean age 49.3) were included for PC from colorectal cancer (26(More)
BACKGROUND Retroperitoneal nodal metastases (RNM) represent 1-2% of metastases from colorectal cancer (CRC). Non-surgical treatments achieve 5-year overall survival (OS) of 0-12%. Radical retroperitoneal lymphadenectomy (RRL) in this setting remains controversial, but most published series do not distinguish local retroperitoneal recurrences from RNM. We(More)
Conventional treatment for locally advanced rectal cancer usually combines neoadjuvant radiochemotherapy and surgery. Until recently, there have been limited predictive factors (clinical or biological) for rectal tumor response to conventional treatment. KRAS, BRAF and PIK3CA mutations are commonly found in colon cancers. In this study, we aimed to(More)
AIM In digestive cancers, the prognostic significance of intraperitoneal free cancer cells remains unclear (IPCC). The main objective of this study was to assess the prognostic significance of IPCC in colorectal and gastric adenocarcinoma. The secondary objectives were to evaluate the predictive significance of IPCC for the development of peritoneal(More)
PURPOSE The majority of colorectal carcinomas diagnosed are adenocarcinomas. Squamous-cell carcinoma is a rare pathologic curiosity. Since 1943, only 18 cases have been described in the medical literature. The aim of this study was to report retrospectively six new cases and to review the medical literature. PATIENTS Of the 6 cases, 4 were females, and(More)
BACKGROUND Insufficient volume of the future liver remnant (FLR) is a major cause of unresectability in patients with bilobar colorectal liver metastases (CLM). The objective of this study was to evaluate the safety and efficacy of the novel associating portal embolization and artery ligation (APEAL) technique before extended right hepatectomy during a(More)
We report 42 cases of gastric cancer with peritoneal carcinosis treated with intraperitoneal chemohyperthermia. Intraperitoneal chemohyperthermia was achieved with a closed sterile circuit containing mitomycin C, 10 mg/l producing an input temperature varying from 46 to 49 degrees C for 90 minutes. There were three postoperative deaths: one pulmonary(More)
AIMS High local failure rates in gastric cancer have been reported, up to 67%. To achieve a better local control, we evaluated intraoperative radiotherapy (IORT) and external beam radiotherapy (EBRT) in association with surgery for gastric cancer patients with lymph node involvement. We report here the analysis of the patterns of failure for patients(More)
STUDY AIM Oncological complete surgery of retroperitoneal tumours may require segmental resection of part of the invaded inferior vena cava. The aim of this retrospective study was to assess whether reconstruction of the inferior vena cava is necessary and presents any advantage. PATIENTS AND METHODS This study included four patients who underwent partial(More)
The purpose of this study was to compare the feasibility and outcomes of two-stage hepatectomy in patients with or without accompanying digestive surgery. We analyzed prospectively data from 56 patients with colorectal liver metastases undergoing two-stage hepatectomy between 1995 and 2009. Patients undergoing associated digestive resection (group I, n =(More)
