Do diabetic complications influence cancer-related events in people with type 2 diabetes? A cohort approach.

Diabetes Metab 2021 Oct 10:101289. Epub 2021 Oct 10.

Institut du thorax, INSERM, CNRS, Université de Nantes, CHU Nantes, Nantes, France.

Aim: To investigate whether diabetic micro- and macrovascular complications (mMVC) influence cancer-related events in people with type 2 diabetes.

Methods: People with type 2 diabetes from the SURDIAGENE cohort were characterized (duration of diabetes, HbA1c, mMVC, history of cancer) and prospectively followed-up for death and cancer-related events (occurrence, dissemination and cancer-related death).

Results: Between 2002 and 2012, 1468 participants (58% men, mean age 64.8 ± 10.7 years, mean duration of diabetes 14.5 ± 9.9 years at baseline) were enrolled. At baseline, 119 (8%) had a personal history of cancer. Incident cancer occurred in 207 (14%) patients during a mean follow-up of 7.3 ± 3.7 years and was associated with older age, smoking status and personal history of cancer. mMVC were not associated with cancer-related events, considering cancer occurrence, node/metastasis dissemination and cancer-specific death. Risk of all-cause mortality was increased in diabetic patients cumulating cancer history and mMVC (HR 1.73, 95%CI 1.25-2.38) compared to those with neither cancer nor mMVC. In our cohort, cancer-related death was not associated with mMVC (HR 1.05, 95%CI 0.67-1.64), but conversely history of cancer was significantly associated with cardiovascular-related death (HR 2.41, 95%CI 1.36-4.26).

Conclusion: In our cohort, mMVC were not associated with cancer-related events, while history of cancer was significantly associated with cardiovascular death.

Comprehensive geriatric assessment in older patients with cancer: an external validation of the multidimensional prognostic index in a French prospective cohort study.

BMC Geriatr 2020 08 18;20(1):295. Epub 2020 Aug 18.

Department of Geriatrics, Poitiers University Hospital, Poitiers, France.

Background: Older patients with cancer require specific and individualized management. The 3-group Multidimensional Prognostic Index (MPI) based on the Comprehensive Geriatric Assessment (CGA) has shown a predictive interest in terms of mortality. The objective of our study was to assess the prognostic value of MPI for 1-year mortality in an external prospective French cohort of elderly patients with cancer.

Methods: From March 2015 to March 2017 a prospective single-center cohort study enrolled all patients with cancer, aged 75 years and older referred to the geriatric oncology clinic. We used a proportional hazard model for 1-year mortality adjusted for age, sex, tumor sites and metastatic status. C-statistics were used to assess the incremental predictive value of MPI index to these risk factors.

Results: overall, 433 patients underwent CGA with MPI (women 42%; mean age 82.8 ± 4.8 years). The most common tumor sites were prostate (23%), skin (17%), colorectum (15%) and breast (12%); 29% of patients had a metastatic disease; 231 patients (53%) belonged to the "MPI-1" group, 172 (40%) to the "MPI-2" group and 30 patients were classified in the "MPI-3" group. One-year mortality rate was 32% (23% in MPI-1, 41% in MPI-2 and 53% in MPI-3, p = 0.024). All domains of MPI except cognition and living status were significantly associated with mortality at one-year, as well as tumor sites and metastatic status. Higher MPI was associated with a higher mortality risk (adjusted HR 1.56 [95%CI 1.70-2.09] and 1.72 [1.33-2.22] for MPI groups 2 and 3 compared to 1; p < 0.0001).

Conclusions: In addition to established risk factors, MPI improves risk prediction of 1-year mortality. This practical prognostic tool may help to optimize management of these vulnerable patients.

Frailty and diabetes status in older patients with cancer: impact on mortality in the ANCRAGE cohort.

Aging Clin Exp Res 2020 Sep 2;32(9):1809-1819. Epub 2020 Jan 2.

Department of Geriatrics, CHU Poitiers, 2 rue de la Milétrie, 86021, Poitiers Cedex, France.

Background: Frailty, diabetes and cancer are associated with aging, but the relationship between these conditions is not well defined.

Aims: We studied older patients with cancer from the prospective single-center cohort ANCRAGE (ANalyses of CanceR in AGEd) aiming to determine the impact of type 2 diabetes (T2D) and its vascular complications (VC) on frailty and adverse outcomes (mortality, unplanned readmission) during follow-up.

Methods: Analysis of cohort patients ≥ 75 years, included between 2009 and 2017, who underwent a comprehensive geriatric assessment (CGA). Variables of interest were history of T2D and VC, tumor site and metastatic status, CGA including eight domains (social environment, functional status, mobility, nutrition, mood, cognition, polypharmacy and comorbidities) and frailty.

Results: Among 1092 patients (47% female, mean age 82 ± 5 years), 219 (20%) had a reported diagnosis of T2D at baseline including 152 (69%) with VC. The most common tumor sites were prostate (15%), breast (15%), skin (12%), and colorectum (11%); 29% of patients had a metastatic disease. Frailty was highly prevalent (84%). During follow-up (median of 15.3 months), 653 (60%) patients died (60% no T2D, 43% T2D without VC, 66% with VC). After adjustment for age, gender and metastatic status, diabetics with VC had a higher risk of all-cause death (aHR1.89, 1.24-2.86, p = 0.004). Death was more frequently due to a non-cancer cause (p < 0.001). No difference in unplanned readmissions was observed in the three groups. Frailty was an independent risk factor for mortality and unplanned readmissions (p < 0.001 both).

Conclusion: In older cancer patients from the prospective ANCRAGE cohort, all-cause mortality was significantly higher in frail patients and those with complicated T2D, a finding questioning the quality of care management in such vulnerable patients, and stimulating further research in this multidisciplinary field.

[Non-programmed hospitalization of elderly patients with cancer: Which care pathway?]

Bull Cancer 2019 Apr 1;106(4):293-303. Epub 2019 Mar 1.

CHU La Milétrie, pôle de gériatrie, 2, rue de La Milétrie, 86021 Poitiers cedex, France.

Introduction: Management of elderly patients with cancer is challenging worldwide. Improvement of their care pathway should focus on unplanned hospitalizations. This study aimed to compare the geriatric and oncologic profiles of elderly patients with cancer, hospitalized for an acute pathology either in medical oncology or acute geriatric medicine units.

Methods: Epidemiological, analytical, monocentric, transversal study performed in the geriatric and oncological short-stay units of the university hospital of Poitiers (France) from 07/01/2014 to 06/30/2015. Only patients with diagnosed cancer prior to hospitalization were included. The geriatric, oncological and hospitalization data were collected and analyzed.

Results: In total, 230 patients were included (156 in geriatrics, 74 in oncology). Alteration of the general condition was the most frequent reason for admission. In multivariate age-adjusted analyses, factors associated with admission to a geriatric unit were co-morbidities (OR=0.18 [95% CI: 0.07-0.46], P<0.01) and dependence (OR=0.07 [95% CI: 0.01-0.36], P<0.01). Ongoing antineoplastic treatment (OR=2.60 [95%CI: 1.14-5.89], P=0.02) and metastatic cancer (OR=2.63 [95%CI: 1.18-5.86], P=0.02) influenced hospitalization in the oncology unit. During the hospital stay there was more frequent psychological support in oncology (OR=45.59 [95%CI: 9.79-212.23], P<0.01) and social support in Geriatrics (OR=0.13 [95% CI: 0.04-0.40], P<0.01).

Conclusion: This first comparative study showed a significant difference in profiles of elderly patients with cancer hospitalized for an acute problem, depending on the hospital unit. This finding paves the way of improvement of care pathway by formalizing links between these two departments to optimize care and referrals to the most appropriate care unit, according to patients condition, in case of unscheduled hospitalization.

Prognosis of geriatric patients with severe kidney disease.

Geriatr Psychol Neuropsychiatr Vieil 2018 Dec;16(4):376-382

Pôle de gériatrie, CHU de Poitiers, Poitiers, France, Inserm, CIC1402, CHU de Poitiers, France.

Over three million French people present a severe chronic kidney disease, among which there is a high prevalence of elder subjects. We conducted a prospective monocentric study in a geriatric acute care ward. The aims were to determine the short-term prognosis of patients with severe chronic kidney disease and to determine the factors associated with mortality at six-months.

Methods: Patients 75 years of age and older, with an estimated glomerular filtration rate (eGFR) < 30 mL/min/1.73 m (chronic kidney disease epidemiology CKD-EPI) were recruited. A comprehensive geriatric assessment was performed at hospital discharge. Comprehensive geriatric assessment was performed: Activities of daily livings and Instrumental activities of daily livings scores, of the risk of pressure sore with Exton-Smith scale, the cognitive status with MMSE score, nutritional status according to Mini-nutritional assessment short form and albuminemia, comorbidities with Cumulative illness rating scale, number of drugs in presciption and living status. Six months follow-up was performed to assess vital status and evolution of the eGFR.

Results: Sixty-seven patients were included, mean age 88.6±4.82 years with a mean eGFR of 21.3±6 mL/min. Mortality rate at six months was 36%. Multivariate analysis showed that a high CIRS score (RR=1.52; IC 95% 1.05-2.19) and a decline of creatinine clearance≥ 2 mL/min (4.72; 1.27-17.52) were predictive of mortality. On the opposite, a high MNA-SF score was protective (0.76; 0.62-0.94).

Conclusion: Prognosis of geriatric patients with severe chronic kidney disease is poor. Comprehensive geriatric assessment helps to assess short-term prognosis, in a focus of person-centered care.

Prevalence of cancer and management in elderly nursing home residents. A descriptive study in 45 French nursing homes.

Eur J Cancer Care (Engl) 2019 Mar 29;28(2):e12957. Epub 2018 Oct 29.

Department of Geriatrics, Poitiers University Hospital, Poitiers, France.

This study aimed to determine cancer prevalence occurring after the age of 75 in 45 French nursing homes (NH), as well as residents' characteristics and parameters associated with cancer-specific management. Descriptive retrospective study including 214 residents (mean age, 89.7 years) with cancer diagnosed after age 75. The studied parameters were sociodemographic, functional, nutritional and cognitive data; comorbidity assessment; date of tumoral diagnosis; cancer type; tumoral stage; treatment plan; multidisciplinary staff decision and oncologic follow-up. Our results showed that cancer prevalence in NH was 8.4 ± 1.1%, diagnosed before admission in 63% of cases. The most common tumoral sites were skin (26%), digestive tract and breast (18% for both); 12% had metastasis. Cognitive impairment was the most common comorbidity (42%), and 44% of the residents were highly dependent. Multivariate analysis showed that therapeutic decisions were associated with age. Older patients had less staging exploration (odd ratios [ORs], 0.90, 95% confidence interval [CI], 0.85-0.97) and underwent less cancer-specific treatment (ORs, 0.92; 95%CI, 0.86-0.99). Oncologic follow-up was more frequent in younger patients (ORs, 0.90; 95%CI, 0.81-0.99) and those with recent diagnosis (ORs, 0.37; 95%CI, 0.23-0.61). This study identified factors associated with substandard neoplastic management in elderly NH residents. It highlights needs for information, education and training in cancer detection to improve cancer consideration and care in NH.
