Management of Esophageal Carcinoma Associated with Cirrhosis: A Retrospective Case-Control Analysis

Objectives. Esophageal carcinoma and cirrhosis have the overlapping etiologic factors. Methods. In a retrospective analysis conducted in 2 Breton institutions we wanted to asses the frequency of this association and the outcome of these patients in a case-control study where each case (cirrhosis and esophageal cancer) was paired with two controls (esophageal cancer). Results. In a 10-year period, we have treated 958 esophageal cancer patients; 26 (2.7%) had a cirrhosis. The same treatments were proposed to the 2 groups; cases received nonsignificantly different radiation and chemotherapy dose than controls. Severe toxicities and deaths were more frequent among the cases. At the end of the treatment 58% of the cases and 67% of the controls were in complete remission; median and 2-year survival were not different between the 2 groups. All 4 Child-Pugh B class patients experienced severe side effects and 2 died during the treatment. Conclusions. This association is surprisingly infrequent in our population! Child-Pugh B patients had a dismal prognosis and a bad tolerance to radiochemotherapy; Child-Pugh A patients have the same tolerance and the same prognosis as controls and the evidence of a well-compensated cirrhosis has not modified our medical options

Salivary gland-sparing other than parotid-sparing in definitive head-and-neck intensity-modulated radiotherapy does not seem to jeopardize local control.

International audienceBACKGROUND: The objective was to analyze locoregional (LR) failure patterns in patients with head-and-neck cancer (HNC) treated using intensity-modulated radiotherapy (IMRT) with whole salivary gland-sparing: parotid (PG), submandibular (SMG), and accessory salivary glands represented by the oral cavity (OC). METHODS: Seventy consecutive patients with Stage I-II (23%) or III/IV (77%) HNC treated by definitive IMRT were included. For all LR failure patients, the FDG-PET and CT scans documenting recurrence were rigidly registered to the initial treatment planning CT. Failure volumes (Vf) were delineated based on clinical, radiological, and histological data. The percentage of Vf covered by 95% of the prescription isodose (Vf-V95) was analyzed. Failures were classified as "in-field" if Vf--V95 >= 95%, "marginal" if 20% < Vf-V95 < 95%, and "out-of-field" if Vf-V95 <=20%. Correlation between Vf-V95 and mean doses (Dmean) in the PG, SMG, and OC was assessed using Spearman's rank-order correlation test. The salivary gland dose impact on the LR recurrence risk was assessed by Cox analysis. RESULTS: The median follow-up was 20 months (6--35). Contralateral and ipsilateral PGs were spared in 98% and 54% of patients, respectively, and contralateral and ipsilateral SMG in 26% and 7%, respectively. The OC was spared to a dose <=40 Gy in 26 patients (37%). The 2-year LR control rate was 76.5%. One recurrence was "marginal", and 12 were "in-field". No recurrence was observed in vicinity of spared structures. Vf-V95 was not significantly correlated with Dmean in PG, SMG, and OC. The LR recurrence risk was not increased by lower Dmean in the salivary glands, but by T (p = 0.04) and N stages (p = 0.03). CONCLUSION: Over 92% of LR failures occurred "in-field" within the high dose region when using IMRT with a whole salivary gland-sparing strategy. Sparing SMG and OC in addition to PG thus appears a safe strategy

Transformation From Atypical to Anaplastic Metastatic Meningioma

International audienceWorld Health Organization (WHO) grade III anaplastic meningioma is scarce. In this way, most studies compared WHO grade I and II. Otherwise, some authors are uncertain about using 18F-FDG as a diagnostic tool to estimate the WHO grade, especially high. We report the case from a man with a grading tumor evolution from WHO grade II atypical to grade III anaplastic metastatic meningioma. This turning point was imaged using 68Ga-DOTATOC and 18F-FDG. Diagnostic was confirmed by histology. The case underlines the unparalleled power of molecular imaging characterized by high sensitivity staging and spectacular avidity changing relationship with grading tumor evolution

Mechanisms of immunomodulation in human glioblastoma.

International audienceGlioblastoma multiforme (GBM), WHO grade IV astrocytoma, is the most dramatic primary brain cancer with a very poor prognosis due to inevitable disease recurrence. Less than 10% of GBM patients are still alive 5 years after diagnosis despite a multimodal treatment with surgical resection of the tumor, radiation therapy and chemotherapy. Cellular immunotherapy in gliomas, one of the promising new therapies, has shown convincing results in some patients with induction of antitumor immune responses and prolonged survival. In particular, several patients treated with dendritic cell vaccinations have demonstrated systemic antigen-specific cytotoxicity and intratumor infiltration of cytotoxic T cells. However, this is not always correlated with clinical improvement because GBM cells have multiple mechanisms that lead to suppression of the patient's antitumor immune responses. This article will focus on some aspects of the systemic immunosuppression observed in GBM patients as well as the multiple mechanisms of local immunoresistance developed by GBM

Evolution of parenteral nutrition practices in a comprehensive cancer center: Comparative audits

International audienceINTRODUCTION: Malnutrition affects 20% to 70% of oncology patients depending on the patient’s age, type and stage of cancer. Two audits were carried out in 2016 and 2019 to evaluate the practice of Parenteral Nutrition (PN). METHODS: Records of adult medical inpatients who received PN between January 1, 2018 and April 30, 2019 were retrospectively analysed. Twenty criteria were defined. We conducted a statistical analysis to compare the two audit data. RESULTS: Between January 1, 2018 and April 30, 2019, 86 hospitalizations with a PN prescription were analysed. Of the 69 patients, 66% were female, the mean and median age was 60 years. These were most often medical oncology patients in palliative care. Gynecological and digestive tumors were the two main tumor localization. Bowel obstruction and palliative care management were the two main reasons for hospitalization. Nutritional assessment, amount of energy prescribed, monitoring, and duration of PN remain with poor results. CONCLUSION: Our study seems to show improvements in the relevance of PN indications, the prescription, and monitoring in patients due to the computerization of prescription and training of professionals. PN remains often prescribed in exclusive palliative situations. We need to continue our improvements, particularly for the initial clinical and biological assessment, and the monitoring. It requires a referral team to improve management of patients treated with PN

Intérêt de la MGMT dans les gliomes. [MGMT analysis in gliomas].

International audienceMGMT status is now regarded as a strong predictive factor of response to standard treatment of newly diagnosed glioblastomas involving temozolomide (TMZ) and radiotherapy. MGMT promoter methylation is also a prognostic factor - independent of treatment - in anaplastic gliomas. The predictive function can be explained by the role of the DNA repair enzyme MGMT, which antagonizes the effects of alkylating agents such as TMZ. MGMT promoter methylation could also reflect a particular molecular phenotype with its own specific prognostic significance. Since MGMT status determination is becoming a crucial biological marker in new clinical glioma trials, and is beginning to be used in day-to-day clinical practice, there is currently a strong need to determine the best technique for MGMT analysis. A French multicenter study has been set up for this purpose

Impressive efficacy of sorafenib in a patient with an hepatocellular carcinoma and a portal vein thrombosis associated with a metastatic ENT cancer.

International audienceSorafenib, a new antiangiogenic and antiproliferative agent, is currently used for hepatocellular and renal cell carcinoma. We report here the case of a patient with two cancers, a locally advanced cancer of the piriform sinus and a hepatocellular carcinoma, who was given sorafenib. Tumor response of both cancers might suggest that sorafenib could be effective against head and neck cancer
