Background: Peritoneal carcinomatosis (PC) from nonovarian malignancies long has been regarded as a terminal disease. Over the past decade, new locoregional therapeutic approaches combining cytoreductive surgery with perioperative intraperitoneal chemotherapy (PIC) have evolved that have demonstrated improved survival. Methods: A retrospective, multicenter cohort study was performed in French-speaking institutions to evaluate toxicity and principal prognostic factors after cytoreductive surgery and PIC (hyperthermic intraperitoneal chemotherapy [HIPEC] and/or early postoperative intraperitoneal chemotherapy [EPIC]) for PC from nongynecologic malignancies. Results: The study included 1290 patients from 25 institutions who underwent 1344 procedures between February 1989 and December 2007. HIPEC was performed in 1154 procedures. The principal origins of PC were colorectal adenocarcinoma (N = 523), pseudomyxoma peritonei (N = 301), gastric adenocarcinoma (N = 159), peritoneal mesothelioma (N = 88), and appendiceal adenocarcinoma (N = 50). The overall morbidity and mortality rates were 33.6% and 4.1%, respectively. In multivariate analysis, patient age, the extent of PC, and institutional experience had a significant influence on toxicity. The overall median survival was 34 months; and the median survival was 30 months for patients with colorectal PC, not reached for patients with pseudomyxoma peritonei, 9 months for patients with gastric PC, 41 months for patients with peritoneal mesothelioma, and 77 months for patients with PC from appendiceal adenocarcinoma. Independent prognostic indicators in multivariate analysis were institution, origin of PC, completeness of cytoreductive surgery, extent of carcinomatosis, and lymph node involvement. Conclusions: A therapeutic approach that combined cytoreductive surgery with PIC was able to achieve long-term survival in a selected group of patients who had PC of nonovarian origin and had acceptable morbidity and mortality. The current results indicated that this treatment should be centralized to institutions with expertise in the management of PC. Copyright © 2010 American Cancer Society.

Background The occurrence and significance of alternans of the ventricular electrogram (VEGM) in patients with an implanted cardioverter-defibrillator (ICD) has been rarely reported. Objectives and Methods This report describes our observations of VEGM alternans documented in nine patients with an ICD (seven new cases and two previously published cases for comparison). Results We found seven new cases of near-field VEGM alternans and added two of our previously reported examples. Catecholaminergic polymorphic ventricular tachycardia (CPVT) was diagnosed in one patient based on ICD recordings. Alternans occurred during ventricular tachycardia (VT) in eight patients. A fast sinus tachycardia could not be ruled out in one patient. Stable cycle length alternans was found in five patients. QRS alternans of the left ventricular (LV) electrogram (EGM) was recorded in all five patients who had a device for cardiac resynchronization therapy capable of sensing by the LV channel. These five cases exhibited corresponding alternans of the right ventricular (RV) EGM in three cases, none in one patient, and a questionable recording in another. Alternans of the far-field (FF) VEGM occurred simultaneously with RV EGM alternans in all four patients whose device provided an FF tracing. Conclusion Ventricular alternans may be more common than realized in ICD patients with VT. The correlation of VEGM alternans with the surface electrocardiogram remains unknown. Although QRS alternans itself as an electrical pattern is generally benign, its cause may not be, as illustrated in our patient with CPVT. Furthermore, associated cycle length alternans or undersensing of the smaller alternans component may complicate ICD therapy. © 2015 Wiley Periodicals, Inc.

Gastric cancer remains a significant health burden worldwide. Most of these Malignancies are diagnosed at an advanced stage and are associated with a grim prognosis.Complete removal of macroscopic and microscopic tumor masses along with regional lymphnodes (R0 surgical resection) represents the treatment of choice in localized, nonmetastatic gastric cancer. Chemotherapy, either alone as a perioperative treatment, or in combination with radiation therapy in an adjuvant setting, improves the clinical outcome for patients with resectable tumors. In patients suffering from metastatic disease, chemotherapy and the so-called targeted therapies play a major role in improving survival and quality of life compared with best supportive care. The emergence of new drugs as well as new administration schedules allow physicians to obtain an objective response of up to 60% and, since the utilization of targeted therapies, overall survival has reached 14 months. In order to situate the standard of care and the latest developments in gastric malignancies better, the pertinent English literature, including major Phase III randomized studies and meta-analyses, has been reviewed. © 2011 Delaunoit.

Background: The use of chemotherapy regimens with moderate or high risk of febrile neutropenia (defined as having a FN incidence of 10% or more) and the respective incidence and clinical management of FN in breast cancer and NHL has not been studied in Belgium. The existence of a medical need for G-CSF primary and secondary prophylaxis with these regimens was investigated in a real-life setting.Methods: Nine oncologists and six hematologists from different Belgian general hospitals and university centers were surveyed to collect expert opinion and real-life data (year 2007) on the use of chemotherapy regimens with moderate or high risk of febrile neutropenia and the clinical management of FN in patients aged <65 years with breast cancer or NHL. Data were retrospectively obtained, over a 6-month observation period.Results: The most frequently used regimens in breast cancer patients (n = 161) were FEC (45%), FEC-T (37%) and docetaxel alone (6%). In NHL patients (n = 39), R-CHOP-21 (33%) and R-ACVBP-14 (15%) were mainly used. Without G-CSF primary prophylaxis (PP), FN occurred in 31% of breast cancer patients, and 13% had PSN. After G-CSF secondary prophylaxis (SP), 4% experienced further FN events. Only 1 breast cancer patient received PP, and did not experience a severe neutropenic event. Overall, 30% of chemotherapy cycles observed in breast cancer patients were protected by PP/SP. In 10 NHL patients receiving PP, 2 (20%) developed FN, whereas 13 (45%) of the 29 patients without PP developed FN and 3 (10%) PSN. Overall, 55% of chemotherapy cycles observed in NHL patients were protected by PP/SP. Impaired chemotherapy delivery (timing and/or dose) was reported in 40% (breast cancer) and 38% (NHL) of patients developing FN. Based on oncologist expert opinion, hospitalization rates for FN (average length of stay) without and with PP were, respectively, 48% (4.2 days) and 19% (1.5 days). Similar rates were obtained from hematologists.Conclusions: Despite the studied chemotherapy regimens being known to be associated with a moderate or high risk of FN, upfront G-CSF prophylaxis was rarely used. The observed incidence of severe neutropenic events without G-CSF prophylaxis was higher than generally reported in the literature. The impact on medical resources used is sizeable. © 2010 Gerlier et al; licensee BioMed Central Ltd.

Development of screening programs in patients with high risk of developing esophageal cancer, as well as recent advances in diagnostic endoscopic techniques, have allowed clinicians to improve early detection of esophageal malignant tumors. Surgical resection, although currently considered as the standard of care for patients with early stage esophageal cancer, is sometimes contra-indicated. In this subset of patients, endoscopic resection techniques including endoscopic mucosal resections (EMR), thermal or non-thermal laser, or cryoablation are amongst the well-recognized modalities safely and efficiently used by gastroenterologists. However, in some patients, these options are contra-indicated or incomplete, necessitating medical treatments such as chemotherapy and/or radiation therapy. A systematic search of all the English literature regarding non-take away approaches has therefore been performed, based on a MEDLINE search (Pubmed) carried out between January 1990 and March 2011. Future radiation therapy developments will also be pointed out.
