Rate and patterns of ICU admission among colorectal cancer patients: a single-center experience.

PURPOSE: The purposes of this study were to evaluate, in colorectal cancer patients, the cause of ICU admission and to find predictors of death during and after hospitalization. METHODS: This is a retrospective study including all patients with colorectal cancer admitted in the ICU of a cancer hospital from January 1st 2003 to December 31 2012. RESULTS: Among 3721 ICU admissions occurring during the study period, 119 (3.2 %) admissions dealt with colorectal cancer, of whom 89 were eligible and assessable. The main reasons for admission were of metabolic (24 %), hemodynamic (19 %), cardiovascular (18 %), gastrointestinal (16 %), respiratory (13 %), or neurologic (6 %) origin. These complications were due to cancer in 43 %, to the antineoplastic treatment in 25 %, or were unrelated to the cancer or its treatment in 33 %. A quarter of the patients died during hospitalization. Independent predictors of death were the Sequential Organ Failure Assessment (SOFA) score (with risk of dying increasing by 42 % per unit of SOFA score), fever (with risk of dying multiplied by three per °C), and high values of GOT (with risk of dying multiplied by 1 % per unit increase), while cancer control (i.e., stage progression or not), compliance to the initial cancer treatment plan, and LDH ≤ median levels had prognostic significance for further longer survival after hospital discharge. CONCLUSION: This is the first study looking at specific causes for unplanned ICU admission of patients with colorectal cancer. Hospital mortality was influenced by the characteristics of the complication that entailed the ICU admission while cancer characteristics retained their prognostic influence on survival after hospital discharge.

[Management of resectable non-small cell lung cancer. Guidelines of clinical practice made by the European Lung Cancer Working Party]. / Traitement des cancers bronchiques non à petites cellules de petit stade. Recommandations de pratique clinique de I'European Cancer Working Party.

The present updated guidelines on the management of resectable non-small cell lung cancer (NSCLC) formulated by the ELCWP are designed to answer the following questions: 1) Is conventional surgery the best treatment for potentially resectable cancer? 2) What is the definition of a complete resection? 3) Should we make a systematic lymphadenectomy in case of surgery for a N0 or N1 tumor? 4) What is the role of radiation therapy after complete resection? 5) In case of clinical stage I or II, should administer adjuvant or neoadjuvant chemotherapy? 6) In case of pathological stage I or II, should administer adjuvant chemotherapy? 7) In case of complete resection for stage IIIA N2 disease, should be offered adjuvant therapy and if so which one: chemotherapy, radiotherapy, chemoradiotherapy? 8) In case of clinical stage IIIA or B, what are the indications for surgery after induction therapy? 9) In case of clinical stage IIIA or B, if surgical indication is retained, should we do an induction treatment, and if so, which one? 10) In case of incomplete resection after primary surgery, what should be the postoperative therapy? 11) In case of (neo)adjuvant chemotherapy, which association should be offered and what dosage of cisplatin to be prescribed? 12) Can stereotactic radiotherapy replace surgery in operable patients? 13) What is proposed for the patient unfit for conventional surgery treatment? 14) Have targeted therapies a place in the treatment ?

[Bad behaviors regarding research and scientific and medical publication]. / Les mauvaises conduites en matière de recherche et de publication scientifique et médicale.

Since a few years, the number of cases of fraud reported in the scientific and medical literature and retraction of articles has increased exponentially. Such fraud is due to fabrication, falsification, theft, embellishment or retention of data, plagiarism, incorrect list of authors or undisclosed conflicts of interest. This tendency has been explained by the need to publish for career advancement or the future of the department, the search for notoriety, the desire to grow rich and the lack of motivation to seek the truth. This crisis can be controlled by measures at different levels: society, universities, scientific institutions, study promoters, scientific and medical journals. A legal framework at EU level would allow to combat such fraud more efficiently.

Surrogate markers predicting overall survival for lung cancer: ELCWP recommendations.

The present systematic review was performed under the auspices of the European Lung Cancer Working Party (ELCWP) in order to determine the role of early intermediate criteria (surrogate markers), instead of survival, in determining treatment efficacy in patients with lung cancer. Initially, the level of evidence for the use of overall survival to evaluate treatment efficacy was reviewed. Nine questions were then formulated by the ELCWP. After reviewing the literature with experts on these questions, it can be concluded that overall survival is still the best criterion for predicting treatment efficacy in lung cancer. Some intermediate criteria can be early predictors, if not surrogates, for survival, despite limitations in their potential application: these include time to progression, progression-free survival, objective response, local control after radiotherapy, downstaging in locally advanced nonsmall cell lung cancer (NSCLC), complete resection and pathological TNM in resected NSCLC, and a few circulating markers. Other criteria assessed in these recommendations are not currently adequate surrogates of survival in lung cancer.

[Richard Doll. A surprising story of conflicts of interest]. / Richard Doll. Une surprenante histoire de conflits d'intérêt.

Richard Doll is a very famous English physician epidemiologist. He is credited with discovering the link between smoking and lung cancer. His reputation was recently vitiated by two facts, ignorance of German studies prior to his work and the existence of major conflicts of interest with industry that led him to minimize the role of chemical products in carcinogenesis.

Validation and comparison of several published prognostic systems for patients with small cell lung cancer.

The aim of the present study was to validate and compare published prognostic classifications for predicting the survival of patients with small cell lung cancer. We pooled data from phase III randomised clinical trials, and used Cox models for validation purposes and concordance probability estimates for assessing predictive ability. We included 693 patients. All the classifications impacted significantly on survival, with hazard ratios (HRs) in the range 1.57-1.68 (all p<0.0001). Median survival times were 16-19 months for the best predicted groups, while they were 6-7 months for the most poorly predicted groups. Most of the paired comparisons were statistically significant. We obtained similar results when restricting the analysis to patients with extensive disease. Multivariate Cox models for fitting survival data were also performed. The HRs for a single covariate were 8.23 (95% CI 5.88-11.69), and 9.46 (6.67-13.50), and for extensive disease were 5.60 (3.13-9.93), 12.49 (5.57-28.01) and 8.83 (4.66-16.64). Concordance probability estimates ranged 0.55-0.65 (overlapping confidence intervals). Published classifications were validated and suitable for use at a population level. As expected, prediction at an individual level remains problematic. A specific model designed for extensive-disease patients did not appear to perform better.

Valproate-doxorubicin: promising therapy for progressing mesothelioma. A phase II study.

No treatment is recommended for patients with malignant mesothelioma (MM) failing after first-line cisplatin-based chemotherapy. In vitro data suggested that valproic acid, a histone deacetylase inhibitor (HDACi), had a proapoptotic effect and synergised with doxorubicin to induce apoptosis in MM cells. Our primary end-point was to determine response rate of combined valproic acid and doxorubicin in patients with unresectable MM failing after platinum-based chemotherapy. Treatment consisted of doxorubicin (60 mg·m⁻²) plus valproic acid. An interim analysis for response rate was planned after the first 16 registered patients. All the cases were centrally reviewed. From July 2006 to March 2009, 45 eligible patients with pleural MM were registered. The majority of the patients were male (73%), had a performance status (PS) ≥ 80 (76%) and an epithelioid subtype (80%). There were seven partial responses (response rate 16%; 95% CI 3-25%), all in patients with PS 80-100. The best disease control rate was 36% (95% CI 22-51%). Two toxic deaths were observed (febrile neutropenia and cerebral thrombotic event), both in patients with poor PS (60-70). Valproic acid, an HDACi, plus doxorubicin appeared an effective chemotherapy regimen in good PS (80-100) patients with refractory or recurrent MM, for which no standard therapy was available.

Invasive mechanical ventilation in cancer patients. Prior non invasive ventilation is a poor prognostic factor.

PURPOSE: Prior non invasive ventilation (NIV) is associated with an increased mortality in patients with haematological malignancies and acute respiratory failure treated by invasive mechanical ventilation (IMV). We have assessed whether NIV failure is an independent prognostic factor for hospital discharge in a general cancer population treated by IMV. METHODS: 106 patients with solid tumors and 58 patients with haematological malignancies were eligible for this retrospective study; 41 were treated by NIV before IMV. RESULTS: The main indications for mechanical ventilation were sepsis/shock (35%), acute respiratory failure (33%), cardiopulmonary resuscitation (16%) and neurologic disease (10%). Respectively, 35%, 28% and 24% of the patients were extubated, discharged from the intensive care unit (ICU) and from the hospital. For patients treated with NIV prior to IMV, the rates were 22%, 17% and 10%, respectively. In multivariate analysis, 3 variables were independently associated with a decreased probability of being discharged from the hospital: NIV use before IMV (odds ratio/OR=0.30, 95% confidence interval/CI: 0.09-0.95; p=0.04); leukopenia (OR=0.21, 95% CI: 0.06-0.77; p=0.02) and serum bilirubin >1.1 mg/dl (OR=0.38, 95% CI: 0.16-0.94; p=0.04). CONCLUSION: NIV failure before IMV is an independent poor prognostic factor in cancer patients treated by IMV.
