The development of a regional referral pathway for locally recurrent rectal cancer: A Delphi consensus study

BACKGROUND

The management of patients with locally recurrent rectal cancer (LRRC) is often complex and requires multidisciplinary input whereas only few patients are referred to a specialist centre. The aim of this study was to design a regional referral pathway for LRRC, in Nouvelle Aquitaine (South-West, France).

METHODS

In 2016, we conducted with a Study Steering Committee (SC) a three phase mixed-methods study including identification of key factors, identification of key stakeholders and Delphi voting consensus. During three rounds of Delphi voting, a consensus was defined as favorable, if at least 80% of participating experts rate the factor, below or equal to 3/10 using a Likert scale, or consider it as "useful" using a binary scale (third round only). Finally, the SC drafted guidelines.

RESULTS

Among the 423 physicians involved in 29 regional digestive Multi-Disciplinary Team (MDT) meeting, 59 participants (from 26 MDT meeting) completed all three rounds of Delphi voting. Thirteen out of twenty initially selected factors reached a favorable consensus. All patients with a LRRC need to be included into a referral pathway. Patients with a central pelvic recurrence offered curative treatment in their local hospital and patients with unresectable metastatic disease were excluded of the referral. Key performance indicators were also agreed including the time to referral and completion of pelvic MRI-, CT-, PET-scan prior to MDT referral.

CONCLUSION

The development of this referral pathway represents an innovative health service, which will improve the management of patients with LRRC in France.

Development of an evidence-based reference framework for care coordination interventions in France

Background

Today, the high variability of practices, the lack of common definitions and underlying concepts increases the existing difficulty to standardise, to replicate, to transpose and to assess the coordinated care. This heterogeneity makes very difficult the evaluation of performance of care coordination. The aim of the first phase of Epock study is to develop a theoretical framework for care coordination interventions in the French health system that can be used for description, implementation and evaluation of care coordination intervention in any clinical situation.

Methods

A review of systematic reviews on care coordination interventions was conducted to identify relevant models and constitutive elements of the expected reference framework for care coordination intervention. These elements resulting from the literature review have been grouped by themes, prioritised and selected by a structured consensus method (Nominal Group Technique).

Results

Four dimensions of care coordination were identified: (a) Underlying conceptual models; (b) Care organization, care and facilitation activities; (c) Actors and tools; and (d) Effects classified according to WHO’s quality of care dimensions. Among these dimensions, 4 to 28 elements have been selected to build the reference components of care coordination in France.

Conclusions

This first reference framework for care coordination interventions in France will be used during the Epock project phase 2 as a basis for comparing practices observed in oncology. This framework could be used as of now for: practice by helping to develop job descriptions and training programmes for future care coordination professionals; piloting to measure care coordination (by developing indicators for care coordination); and research, to evaluate the impact of care coordination interventions.

Key messages

Epock is a challenging French national research project for the development of an evidence-based reference framework for cancer care coordination interventions considered as a complex intervention. Epock will provide key elements for cancer care coordination intervention effective implementations and for designing further medico-economic evaluation of cancer care coordination intervention impact.

EPOCK study protocol: a mixed-methods research program evaluating cancer care coordination nursing occupations in France as a complex intervention

Background

Facing the increasing cancer incidence and cancer survivorship, many national strategic cancer plans have identified cancer care coordination as a priority for health service improvement. However, the high variability of practices, the diversity of definitions and underlying concepts increases the existing difficulty to standardise, replicate, transpose and assess care coordination within the French health system context. The EPOCK national study aims at evaluating practices and the working context of hospital-based cancer care coordination nurses, based on a previously designed reference framework for care coordination within the French health system context.

Methods

EPOCK is based on a comprehensive evaluation of nursing professions in cancer care coordination, considered as a complex intervention. Phase 1 (theoretical phase) will define and design a theoretical reference framework for care coordination in France through an international literature review, aiming to identify relevant models and all components of the expected framework and a structured consensus method, the Nominal group technique, aiming to select and prioritise the most relevant components already found in the literature review with regard to the French healthcare system; phase 2 (Operational phase) will consist in an in-depth analysis of practices, contexts, perceptions and attitudes related to care coordination occupations by nurses in oncology and all stakeholders (related professionals, patients and their caregivers) through a multicentric cross-sectional mixed-method evaluative study. The observed practices and contexts will be finally compared with the theoretical reference framework using both inductive and deductive approaches.

Discussion

This study will result in an evaluation framework identifying key models and key elements relative to cancer care coordination interventions that can be used to guide management of cancer care coordination nursing occupations within the French healthcare system. EPOCK would also assist in public decision-making to identify optimal targets, skills profiles and scope of actions for cancer coordination professions. Finally, EPOCK will describe typology of nurse practices in cancer care coordination and thus obtain precise preliminary information essential for drafting a medico-economic evaluation study of these new nursing professions’ impact.

Consistency and inconsistency in testing biomarkers in breast cancer. A GRELL study in cut-off variability in the Romance language countries

PURPOSE

Biological markers are crucial factors in order to differentiate female breast cancers and to determine the right therapy. This study aims at evaluating whether testing for biomarkers for female breast cancer has similar frequency and characteristics across and within countries.

METHODS

Population-based cancer registries of the Association for cancer registration and epidemiology in Romance language countries (GRELL) were asked to complete a questionnaire on biomarkers testing. The data collected referred to invasive female breast cancer cases diagnosed between 2004 and 2009. The investigation focused on 1) the overexpression and amplification of the human epidermal growth factor receptor 2 oncogene (HER2); 2) the expression of oestrogen (ER) and progesterone (PgR) receptors; and 3) the proliferation index (PI). Weighted percentages, the heterogeneity among and within countries, and the correlation between responses and calendar years were evaluated. The study was based on 19,644 breast cancers.

RESULTS

Overall, 85.9% of the cases were tested for HER2, 91.8% for both ER and PgR, and 74.1% for proliferative markers. For HER2 and ER-PgR, the frequency of testing increased from 2004 to 2009. Testing varied among countries (HER2 from 82.0% to 95.9%, ER-PgR from 89.3% to 98.9%, PI from 10% to 92%) and also within the same country (e.g. HER2 in Italy from 51% to 99%) as well as within single cancer registries. The most relevant differences were in the scores for positive/negative/not clearly defined HER2 (e.g. HER2 was defined positive if IHC 3+ in 21/33 registries), and in the cut-off of positive cells for ER/PgR (from >0% to >30%) and PI positivity (from >0% to >20%).

CONCLUSIONS

Biological markers are widely tested in the Romance language countries; however, the parameters defining their positivity may vary, raising concerns about homogeneity in breast cancer classification and treatment.

Lingual thyroid causing dysphagia and dyspnoea. Case reports and review of the literature

Lingual thyroid is a rare embryological anomaly and originates from failure of the thyroid gland to descend from the foramen caecum to its normal eutopic pre-laryngeal site. The ectopic gland located at the base of the tongue is often asymptomatic but may cause local symptoms such as dysphagia, dysphonia with stomatolalia, upper airway obstruction and haemorrhage, often with hypothyroidism. Two cases are presented, one in a 62-year-old female and the other in a 42-year-old female, both of whom complained of sensation of a foreign body and progressive dysphagia and dyspnoea caused by ectopic lingual thyroid. Treatment was performed with a partial endoscopic removal and an external cervical approach, followed by substitutive hormone treatment, respectively. Diagnostic procedures and therapeutic options are discussed and a review has been made of reports of lingual thyroid appearing in the literature.

Hepatitis B vaccination in HIV-infected patients: a survey of physicians and patients participating in the Aquitaine cohort

In France, HIV-infected (HIV+) patients are frequently coinfected with hepatitis B virus (HBV) or at risk for this infection. Physicians and their patients should be more committed to HBV prevention than the average population.

AIMS

To gain insight into the attitude towards HBV and its vaccination in HIV+ patients from the Aquitaine Cohort and their attending physicians in France.

METHODS

A cross-sectional survey based on self-administered questionnaires was performed from November 2002 to June 2003. It targeted 198 physicians from the clinical group on AIDS epidemiology (Groupe d'Epidémiologie Clinique du SIDA en Aquitaine, GECSA) or participating in medical HIV networks in southwestern France; and 512 patients from the cohort. Questions concerned the following items for the physicians: HBV status, prescription of HBV serology and vaccination (frequency, type, schedule), risk factors assessed, reasons for non-vaccination; and for the patients: HBV status, information received, risk factors, attitude towards vaccination.

RESULTS

93% of physicians and 22% of patients stated they were vaccinated against HBV. HBV serological status was reported to be systematically ascertained by 75% of physicians, but post-vaccinal testing was only prescribed by 23% of them. The main reasons for not prescribing more often HBV vaccine were forgetting (79%), difficulty to identify subjects at risk (44%) and being afraid of post-vaccinal complications (32%). Thirty percent of patients reported not to have received any information on HBV vaccination. Overall, 44% considered not to be at risk of infection but 82% of them had been confronted with at least one risk. The main reasons for not having been vaccinated were mostly worry about AIDS (70%), not having been asked by physician (65%) or afraid of complications (58%); nonetheless, 42% of patients were willing to be vaccinated.

CONCLUSIONS

Results from this survey underline the need for specific health actions to be undertaken concerning hepatitis B vaccination in HIV+ patients as well as their health care providers.

Surveillance of acute hepatitis C in Cairo, Egypt

Surveillance of acute hepatitis has been set up in two fever hospitals in Cairo to diagnose acute hepatitis C. Patients were categorized as definite acute hepatitis C with positive hepatitis C virus (HCV) RNA and without anti-HCV antibody, or probable acute hepatitis C with positive HCV RNA, positive anti-HCV antibody, alanine aminotransferase >/=4 times the upper limit of normal (ULN), and high risk parenteral exposure in the 1--3 months prior to the beginning of symptoms. From May to November 2002, 315 patients were recruited in the study. Of these, 115 (36.5%) had acute hepatitis A, 89 (28.3%) had acute hepatitis B, and 111 (35.2%) had non-A non-B acute hepatitis. Of the total with complete data (n=309), 12 (3.9%, 95% CI=2.0%-6.7%) had definite acute hepatitis C, and 11 (3.6%, 95% CI=1.8%-6.3%) had probable acute hepatitis C. In patients with definite acute hepatitis C, dental exposure (n=5) and intravenous drug use (n=2), were the only high risk procedures found in the 6 months prior to diagnosis. Five patients had no identifiable parenteral exposure. In conclusion, results from this study suggest that acute hepatitis C can be diagnosed by surveillance of acute hepatitis in hospital settings in Cairo and that minor community exposures contribute substantially to local HCV transmission.

Biochemical and regulatory effects of methionine analogues in Saccharomyces cerevisiae

The effect of three methionine analogues, ethionine, selenomethionine, and trifluoromethionine, on the biosynthesis of methionine in Saccharomyces cerevisiae has been investigated. We have found the following to be true. (i) A sharp decrease in the endogenous methionine concentration occurs after the addition of any one of these analogues to growing cells. (ii) All of them can be transferred to methionine transfer ribonucleic acid in vitro as well as in vivo with, as a consequence, their incorporation into proteins. In the absence of radioactive trifluoromethionine, this conclusion results from experiments of an indirect nature and must be taken as an indication rather than a direct demonstration. (iii) Ethionine and selenomethionine can be activated as homologues of S-adenosylmethionine, whereas trifluoromethionine cannot. (iv) All of them can act as repressors of the methionine biosynthetic pathway. This has been shown by measuring the de novo rate of synthesis of methionine in a culture grown in the presence of any one of the three analogues.
