A propensity-score-matched analysis of laparoscopic vs open surgery for rectal cancer in a population-based study.

AIM: The oncological risk/benefit trade-off for laparoscopy in rectal cancer is controversial. Our aim was to compare laparoscopic vs open surgery for resection of rectal cancer, using unselected data from the public healthcare system of Catalonia (Spain). METHODS: This was a multicentre retrospective cohort study of all patients who had surgery with curative intent for primary rectal cancer at Catalonian public hospitals from 2011 to 2012. We obtained follow-up data for up to 5 years. To minimize the differences between the two groups, we performed propensity score matching on baseline patient characteristics. We used multivariate Cox proportional hazards regression analyses to assess locoregional relapse at 2 years and death at 2 and 5 years. RESULTS: Of 1513 patients with Stage I-III rectal cancer, 933 (61.7%) had laparoscopy (conversion rate 13.2%). After applying our propensity score matching strategy (2:1), 842 laparoscopy patients were matched to 517 open surgery patients. Multivariate Cox analysis of death at 2 years [hazard ratio (HR) 0.65, 95% CI 0.48, 0.87; P = 0.004] and 5 years (HR 0.61, 95% CI 0.5, 0.75; P < 0.001) and of local relapse at 2 years (HR 0.44, 95% CI 0.27, 0.72; P = 0.001) showed laparoscopy to be an independent protective factor compared with open surgery. CONCLUSIONS: Laparoscopy results in lower locoregional relapse and long-term mortality in rectal cancer in unselected patients with all-risk groups included. Studies using long-term follow-up of cohorts and unselected data can provide information on clinically relevant outcomes to supplement randomized controlled trials.

Influence of age on variation in patterns of care in patients with rectal cancer in Catalonia (Spain)

Background: Population ageing is a relevant concern in people diagnosed with rectal cancer. This study evaluates the adherence to clinical practice guidelines (CPGs) and patient outcomes in rectal cancer, with a particular focus on variation according to age. Methods: This is a multicentre retrospective cohort study of all patients surgically treated for the first time for primary rectal cancer with curative intent in public hospitals in Catalonia during two study periods: first, with data from 2005 to 2007, and then with data from 2011 to 2012. We obtained the study data through a comprehensive review of patients’ clinical records. Information on diagnosis, treatment and follow-up was collected and then compared with the relevant CPGs. We then performed a descriptive analysis of the categorical variables followed by a univariate and multivariate logistic regression analysis to calculate the odds ratio. Finally, we calculated the recurrence and death rates per person-year at 2 years’ follow-up. Results: In total, 3770 people were included in this study. The participants aged 70 and under were more likely to receive neoadjuvant therapy than those aged over 80 (2005/2007, 63 vs 17.4% p < 0.001; 2011/2012, 72 vs 41.1% p < 0.001); however, in the second study period there was less imbalance between the two groups in this regard, showing improved administration of neoadjuvant therapy in the elderly. The quality of surgery was suboptimal in a larger proportion of the elderly population, and the choice of surgical technique was dependent to some extent on the age of the participant. Recurrence and survival rates were significantly better in the second study period. Conclusions: Compared to younger patients, the most elderly were less likely to receive the recommended adjuvant treatment, laparoscopy and total mesorectal excision. However, we observed improved adherence to the recommended treatment regimen in the most elderly participants, resulting in decreased recurrence and increased survival rates in this population

Clinical Audit of the Radiotherapy Process in Rectal Cancer: Clinical Practice Guidelines and Quality Certification Do Not Avert Variability in Clinical Practice.

BACKGROUND: The therapeutic approach to cancer is complex and multidisciplinary. Radiotherapy is among the essential treatments, whether used alone or in conjunction with other therapies. This study reports a clinical audit of the radiotherapy process to assess the process of care, evaluate adherence to agreed protocols and measure the variability to improve therapeutic quality for rectal cancer. METHODS: Multicentre retrospective cohort study in a representative sample of patients diagnosed with rectal cancer in the Institut Català d'Oncologia, a comprehensive cancer centre with three different settings. We developed a set of indicators to assess the key areas of the radiotherapy process. The clinical audit consisted of a review of a random sample of 40 clinical histories for each centre. RESULTS: The demographic profile, histology and staging of patients were similar between centres. The MRI reports did not include the distance from tumour to mesorectal fascia (rCRM) in 38.3% of the cases. 96.7% of patients received the planned dose, and 57.4% received it at the planned time. Surgery followed neoadjuvant treatment in 96.7% of the patients. Among this group, postoperative CRM was recorded in 65.5% of the cases and was negative in 93.4% of these. With regard to the 34.5% (n = 40) of cases where no CRM value was stated, there were differences between the centres. Mean follow-up was 3.4 (SD 0.6) years, and overall survival at four years was 81.7%. CONCLUSIONS: The audit revealed a suboptimal degree of adherence to clinical practice guidelines. Significant variability between centres exists from a clinical perspective but especially with regard to organization and process.

Improving survival and local control in rectal cancer in Catalonia (Spain) in the context of centralisation: A full cycle audit assessment.

BACKGROUND: Rectal cancer surgery in Catalonia has been involved in a process of centralisation. We assessed the impact of this health policy strategy on quality of care and clinical results. METHODS: We compared patterns of care and clinical outcomes of all rectal cancer patients receiving radical surgery for the first time in public hospitals in two time periods, before (2005 and 2007) and after (2011-2012) centralisation, analysing indicators of care quality according to the regional clinical practice guidelines. Clinical outcomes at two years were also assessed. RESULTS: A total of 3780 patients were included. From 2005 to 2012, the proportion of patients treated surgically for the first time in centres whose annual surgical caseload was more than 11 increased from 84.0% to 90.4%. The rate of locoregional recurrence at two years fell from 4.5 to 3.06/100 person-years (p = 0.005). The crude mortality rate at three months, one and two years was reduced by 55%, 40% and 34% (p < 0.001). CONCLUSION: Improvements in quality of care might be associated with the centralisation of surgery and with the selective focus effect derived from the process of auditing. Our results support the continuation of clinical auditing and surveillance of authorised centres.

Multidisciplinary cancer care may impact on the postoperative mortality and survival of patients with oesophageal and oesophagogastric junction cancer: a retrospective cohort study

Background. Modern management of Oesophageal and oesophagogastric junction (OGJ) cancers requires a multidisciplinary approach, which was implemented at our health centre in 2005. This study aimed to assess the impact of this change on clinical outcomes. Methods. A retrospective cohort study was conducted, covering all patients treated for oesophageal and OGJ cancer at the cancer centre established by the Bellvitge University Hospital and Catalonian Institute of Oncology, over two time periods, i.e. 2000–2004 and 2005–2008. Descriptive and multivariate analyses were performed using survival at 1 and 3 years as dependent variables. Results. Between 1 January 2000 and 31 December 2008, 586 patients were included. Number of patients with unknown stage at diagnosis was significantly reduced. Preoperative strategies at the oesophageal location clearly increased in the recent period. A multidisciplinary approach resulted in a significant reduction in surgical mortality (11.8 vs. 2 %) in the period 2005–2008. Analysis restricted to patients undergoing surgery with curative intent indicated a significant increase in 1- and 3-year survival in the latter period (68.4 vs. 89.8 and 38.2 vs. 57.1 %, respectively). Multivariate analysis showed that variables associated with improved survival were: age; tumour stage; radical intent of treatment (surgery and radical combined chemoradiotherapy); and therapeutic strategy. Conclusion. Better selection of patients for therapy together with improved staging resulted in a significant improvement in 1- and 3-year survival in cases undergoing surgery with curative intent. These changes would support the adoption of a multidisciplinary approach to clinical decision-making in cases of oesophageal and OGJ cancer (AU)

Síndrome de fatiga crónica: estudio de una serie consecutiva de 824 casos evaluados en dos unidades especializadas / Chronic fatigue syndrome: study of a consecutive series of 824 cases assessed in two specialized units

Fundamento y objetivo. El síndrome de fatiga crónica (SFC) condiciona una importante limitación funcional. En nuestro medio se disponen de escasos estudios sobre las características del SFC, por lo que se inició el estudio de una serie consecutiva de casos diagnosticados en dos unidades especializadas. Pacientes y método. Se han incluido todos los pacientes con SFC atendidos desde enero de 2008 hasta junio de 2010. Se analizaron datos sociodemográficos y laborales, tiempo desde el inicio, factores desencadenantes y forma de inicio, criterios diagnósticos de Fukuda y canadienses, los fenómenos comórbidos y el tratamiento. Resultados. Se incluyeron 824 pacientes, 748 (91%) mujeres, con una edad media de 48±9 años. La edad media de inicio de los síntomas fue de 35±11 años, el tiempo transcurrido hasta el diagnóstico fue de 108±88 meses. En 481 pacientes (58%) se identificó un factor desencadenante y en 517 (63%) el inicio fue gradual. En 515 (62,5%) pacientes la enfermedad estaba inactiva. Entre los criterios diagnósticos de Fukuda destacó la fatiga postejercicio físico, el sueño no reparador y las alteraciones en la concentración y memoria inmediata. Los bloques sintomáticos de los criterios canadienses mostraron la uniformidad de los síntomas. Los fenómenos comórbidos acompañantes fueron: ansiedad 691 (84%), síndrome seco 678 (82%) y fibromialgia 450 (55%). Realizaban tratamiento farmacológico 520 (63%) pacientes. Conclusiones. El SFC afecta preferentemente a mujeres jóvenes, condiciona importante ausentismo laboral. Entre los criterios diagnósticos destacó la intolerancia al ejercicio físico, la disfunción neurocognitiva y el sueño no reparador. En la valoración del paciente, es muy importante la aplicación de los criterios canadienses y estudiar la comorbilidad(AU)

Background and objective. The chronic fatigue syndrome (CFS) is a disabling disorder. Few studies are available in our area on the prevalence and characteristics of CFS. Therefore, we carried out a study of a consecutive series of 824 cases diagnosed in two specialized units. Patients and methods. We evaluated all of the CFS patients seen from January 2008 to June 2010. We analyzed social and demographic data, employment status, time of clinical evolution, trigger factors and onset, Fukuda and Canadian criteria, associated comorbidities and treatment. Results. A total of 824 patients were included, 748 (91%) woman, mean age 48±9 years. Average age of onset of symptoms was 35±11 years, time to diagnosis 108±88 month. A precipitating factor was identified in 481 (58%) patients, the onset was gradual in 517 (63%) and 515 (62.5%) were not employed. The most outstanding diagnostic criteria of Fukuda were prolonged generalized fatigue after exercise, sleep disturbance and impairments in concentration and short-term memory. The different groups of symptoms defined by the Canadian consensus showed that CFS is a homogeneous entity. Accompanying comorbidity phenomena were anxiety 691 (83%), sicca syndrome 678 (82%), fibromyalgia 450 (55%). A total of 63% of patients (520) received pharmacological treatment. Conclusions. CFS is an illness that preferentially affects young women and results in employment absenteeism. The most relevant clinical features were prolonged generalized fatigue after exercise, neurocognitive impairment and sleep disturbance. In the evaluation of the patient, it is very important to apply the Canadian criteria and to assess comorbidity(AU)

Variability in the quality of rectal cancer care in public hospitals in Catalonia (Spain): clinical audit as a basis for action.

AIM: Clinical practice guidelines in cancer are a relevant component of Catalonian Cancer Strategy aimed at promoting equity of access to therapy and quality of cancer care. The colorectal cancer (CRC) guideline was first published in 2003 and subsequently updated in 2008. This study examined the quality of therapy administered to patients with rectal cancer in public hospitals in Catalonia (Spain) in 2005 and 2007, according to CRC guideline recommendations. METHODS: We conducted a multicentre retrospective cohort study of patients who underwent curative-intent surgery for primary rectal cancer at Catalonian public hospitals in 2005 and 2007. Data were drawn from clinical records. RESULTS: The study covered 1831 patients with rectal cancer. Performance of total mesorectal excision (TME) was poorly reported by surgeons (46.4%) and pathologists (36.2%). Pre-operative radiotherapy was performed on 52% of stage-II and -III patients. Compared to high-caseload hospitals, those with a low caseload (≤11 cases/year) registered more Hartman's procedures, worse TME quality, a higher rate of post-operative complications and lower adherence to recommended pre-operative radio-chemotherapy. CONCLUSIONS: Reporting quality of care is essential for ascertaining current performance status and opportunities for improvement. In our case, there is a need for the quality of the information included in clinical records to be improved, and variability in adherence to guideline recommendations to be reduced. In view of the fact that heterogeneity in the quality of the health care process was linked to hospital caseload, the health authorities have decided to reorganise the provision of rectal cancer care.
