Peritoneal carcinomatosis from gastric cancer: a multi-institutional study of 159 patients treated by cytoreductive surgery combined with perioperative intraperitoneal chemotherapy

BACKGROUND: Peritoneal carcinomatosis (PC) from gastric cancer has long been regarded a terminal disease with a short median survival. New locoregional therapeutic approaches combining cytoreductive surgery with perioperative intraperitoneal chemotherapy (PIC) have evolved and suggest improved survival. MATERIALS AND METHODS: A retrospective multicentric study was performed in French-speaking centers to evaluate the toxicity and the principal prognostic factors in order to identify the best indications. All patients had cytoreductive surgery and PIC: hyperthermic intraperitoneal chemotherapy (HIPEC) and/or early postoperative intraperitoneal chemotherapy (EPIC). RESULTS: The study included 159 patients from 15 institutions between February 1989 and August 2007. The median follow-up was 20.4 months. HIPEC was the PIC used for 150 procedures. Postoperative mortality and grade 3-4 morbidity rates were 6.5 and 27.8%, respectively. By multivariate analysis, the institution had a significant influence on toxicity. The overall median survival was 9.2 months and 1-, 3-, and 5-year survival rates were 43, 18, and 13%, respectively. The only independent prognostic indicator by multivariate analysis was the completeness of cytoreductive surgery. For patients treated by complete cytoreductive surgery, the median survival was 15 months with a 1-, 3-, and 5-year survival rate of 61, 30, and 23%, respectively. CONCLUSIONS: The therapeutic approach combining cytoreductive surgery with PIC for patients with gastric carcinomatosis may achieve long-term survival in a selected group of patients (limited and resectable PC). The high mortality rate underlines this necessarily strict selection that should be reserved to experienced institutions involved in the management of PC and gastric surgery

Small bowel involvement is a prognostic factor in colorectal carcinomatosis treated with complete cytoreductive surgery plus hyperthermic intraperitoneal chemotherapy

<p>Abstract</p> <p>Background</p> <p>Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (HIPEC) is a promising treatment for patients with peritoneal carcinomatosis (PC). Our objective was to identify new prognostic factors in patients with PC from colorectal cancer treated with this procedure.</p> <p>Methods</p> <p>All patients with PC from colorectal cancer treated by HIPEC from January 2000 to December 2007 were prospectively included. The tumor extension was assessed by the Peritoneal Cancer Index (PCI) and the residual disease was recorded using the completeness cytoreductive score (CCs). All clinical and treatment data were computed in univariate and multivariable analyses using survival as primary end point.</p> <p>Results</p> <p>We carried out 51 complete procedures in 49 consecutive patients. The mean PCI was 10. The allocation of CCs was: CC-0 = 37, CC-1 = 14. The five-year overall and progression-free survival rate were 40% and 20%, respectively. Several prognostic factors for survival were identified by univariate analysis: PCI < 9 (<it>P </it>< 0.001), CC-0 vs. CC-1 (<it>P </it>< 0.01) and involvement of area 4 (<it>P </it>= 0.06), area 5 (<it>P </it>= 0.031), area 7 (<it>P </it>= 0.014), area 8 (<it>P </it>= 0.022), area 10 (<it>P </it>< 0.0001), and area 11 (<it>P </it>= 0.02). Only the involvement of the distal jejunum (area 10) was significant in the multivariable analysis (<it>P </it>= 0.027).</p> <p>Conclusions</p> <p>We demonstrated that the involvement of area 10 (distal jejunum of the PCI score) was an independent factor associated with poor prognosis.</p

Swallowing a safety pin: Report of a case

Ingestion of a foreign body is a frequent and well-known medical problem with several diagnostic and therapeutic approaches. Usually, ingested foreign bodies pass through the alimentary tract without incident. In some cases, they can be lodged in the appendix and may cause appendicitis. We report a case of a 29-year old woman, suffering from mental illness, with a safety pin lodged in the appendix. Initially, the patient consulted for abdominal pain. After a period of waiting, during which time the foreign body did not move, a colonoscopy was performed but failed to see the safety pin. Then, the patient underwent a laparoscopic appendectomy. Pathological examination showed an ulcerative appendicitis

Pseudomyxoma peritonei: a French multicentric study of 301 patients treated with cytoreductive surgery and intraperitoneal chemotherapy

International audienceTo analyze a large series of patients with pseudomyxoma peritonei (PMP) treated with cytoreductive surgery associated with perioperative intraperitoneal chemotherapy (PIC) in 18 French-speaking centers

The judicial efficiency of Brazilian Labor Courts: a jurimetric analysis based on DEA (Data Envelopment analysis)

Brazilian political and judicial system has considered the principle of judicial efficiency due to some changes of 1988 Brazilian Federal Constitution and the creation of the National Council of Justice (CNJ) in 2009. This paper presents the measurement of the judicial efficiency of the Brazilian Labor Courts (TRTs) from 2009 to 2014. The results suggest that among the 24 TRTs, eight of them had improvements in their technical efficiency, eleven labor courts have worsened and five showed no change in their efficiency score. It also suggests that the least efficient Brazilian labor courts were increasing in returns to scale
