Total registration of non-Hodgkin's lymphoma and Hodgkin's disease in Scotland: effect of deprivation and caseload on outcome

Overview of lymphoma diagnosis in Brazilian public health system patients: Open data analysis for health care planning

Introduction

Knowing the information regarding the panorama of lymphoma diagnosis in patients treated in the Brazilian Public Unified Health System from the last 10 years is a challenge for Strategic Health Planning.

Objective

To characterize the Brazilian population with lymphoma treated in the Brazilian Public Unified Health System between 2008 and 2017 regarding staging, sex, residence site and mortality.

Material and methods

A descriptive, retrospective, and longitudinal trial with secondary data from DataSUS (SIA/SUS and SIM/SUS) obtained from patients with ICD-10 C81−85.

Results

There were 70,850 lymphoma cases between 2008 and 2017, of which 55% were male, the median age was 51 years, and 27% had Hodgkin Lymphoma. Most patients (56%) were treated outside the residence city. São Paulo State accounted for 25% of patients. Treatment initiation took more than 60 days in 27% of cases. A total of 45,601 deaths were due to lymphoma (12% Hodgkin Lymphoma and 88% Non-Hodgkin Lymphoma), with a median age 63 years, and were mainly males (55%). Staging data were inadequate in 23% of patients, and analysis was performed only on the valid records. Advanced disease was diagnosed in 58% of patients (60% male; 57% female) and was more common in Non-Hodgkin Lymphoma (62%) versus Hodgkin Lymphoma (49%).

Discussion

Late diagnosis interferes with mortality rates. Health promotion and cancer prevention campaigns, especially targeting the male public, and training for early diagnosis and early treatment are needed.

Conclusion

Effective measures for early diagnosis and treatment are urgently needed for lymphoma control.

Analyzing the effect of physician assignment in the survival of patients with advanced non-small-cell lung cancer

Background

Non-small-cell lung cancer (nsclc) is the most common cause of cancer deaths worldwide, with a 5-year survival of 17%. The low survival rate observed in patients with nsclc is primarily attributable to advanced stage of disease at diagnosis, with more than 50% of cases being stage iv at presentation. For patients with advanced disease, palliative systemic therapy can improve overall survival (os); however, a recent review at our institution of more than 500 consecutive cases of advanced nsclc demonstrated that only 55% of the patients received palliative systemic therapy. What is unknown to date is whether that observed low rate of systemic therapy in our previous study is uniform across oncologists.

Methods

With ethics approval, we performed a retrospective analysis of newly diagnosed patients with stage iv nsclc seen as outpatients at our institution between 2009 and 2012 by 4 different oncologists. Demographics, treatment, and survival data were collected and compared for the 4 oncologists.

Results

The 4 oncologists saw 528 patients overall, with D seeing 115; L, 158; R, 137; and M, 118. Significant variation was observed in the proportion receiving 1 line or more of chemotherapy: D, 60%; L, 65%; R, 43%; and M, 52%. Physician assignment was not associated with a difference in median os, with D's cohort having a median os of 6.8 months; L, 8.4 months; R, 7.0 months; and M, 7.0 months.

Conclusions

Practice size and proportion of patients treated varied between oncologists, but those differences did not translate into significantly different survival outcomes for patients.

Affluence and Private Health Insurance Influence Treatment and Survival in Non-Hodgkin's Lymphoma

BACKGROUND

The aim of this study was to investigate inequalities in survival for non-Hodgkin's lymphoma (NHL), distinguishing between direct and indirect effects of patient, social and process-of-care factors.

METHODS

All cases of NHL diagnosed in Ireland in 2004-2008 were included. Variables describing patient, cancer, stage and process of care were included in a discrete-time model of survival using Structural Equation Modelling software.

RESULTS

Emergency admissions were more common in patients with co-morbid conditions or with more aggressive cancers, and less frequent for patients from more affluent areas. Aggressive morphology, female sex, emergency admission, increasing age, comorbidity, treatment in a high caseload hospital and late stage were associated with increased hazard of mortality. Private patients had a reduced hazard of mortality, mediated by systemic therapy, admission to high caseload hospitals and fewer emergency admissions.

DISCUSSION

The higher rate of emergency presentation, and consequent poorer survival, of uninsured patients, suggests they face barriers to early presentation. Social, educational and cultural factors may also discourage disadvantaged patients from consulting with early symptoms of NHL. Non-insured patients, who present later and have more emergency admissions would benefit from better access to diagnostic services. Older patients remain disadvantaged by sub-optimal treatment, treatment in non-specialist centres and emergency admission.

Socioeconomic position, treatment, and survival of non-Hodgkin lymphoma in Denmark--a nationwide study

Background:

Not all patients have benefited equally from the advances in non-Hodgkin lymphoma (NHL) survival. This study investigates several individual-level markers of socioeconomic position (SEP) in relation to NHL survival, and explores whether any social differences could be attributed to comorbidity, disease and prognostic factors, or the treatment given.

Methods:

This registry-based cohort study links clinical data on prognostic factors and treatment from the national Danish lymphoma database to individual socioeconomic information in Statistics Denmark including 6234 patients diagnosed with NHL in 2000–2008.

Results:

All-cause mortality was 40% higher in NHL patients with short vs higher education diagnosed in the period 2000–2004 (hazard ratio (HR)=1.40 (1.27–1.54)), and 63% higher in the period 2005–2008 (HR=1.63 (1.40–1.90)). Further, mortality was increased in unemployed and disability pensioners, those with low income, and singles. Clinical prognostic factors attenuated, but did not eliminate the association between education and mortality. Radiotherapy was less frequently given to those with a short education (odds ratio (OR)= 0.84 (0.77–0.92)), low income (OR=0.80 (0.70–0.91)), and less frequent to singles (OR=0.79 (0.64–0.96)). Patients living alone were less likely to receive all treatment modalities.

Conclusion:

Patients with low SEP have an elevated mortality rate after a NHL diagnosis, and more advanced disease at the time of diagnosis explained a part of this disparity. Thus, socioeconomic disparities in NHL survival might be reduced by improving early detection among patients of low SEP.

State-of-the-art issues in Hodgkin's lymphoma survivorship

The prognosis of Hodgkin's lymphoma (HL) has markedly improved as management strategies evolved. In the modern era, less than 15% of patients with early-stage, non-bulky HL will relapse, and less than one third of those with advanced disease will relapse. As therapy for HL intensified, and as disease-related outcomes improved, the impact of the late effects of therapy has become increasingly important. There is a growing body of literature describing the late morbidity experienced by survivors of HL, including risks of second primary malignancy, cardiac disease, pulmonary disease, and endocrine dysfunction. Additionally, the impact of disease and treatment on psychosocial function and quality of life has been a subject of investigation, with survivors often suffering from impairment. An understanding of these risks and the management implications inherent to them is central to the care of survivors of HL.

Socioeconomic inequalities in prognostic markers of non-Hodgkin lymphoma: analysis of a national clinical database

The survival of non-Hodgkin lymphoma patients strongly depends on a range of prognostic factors. This registry-based clinical cohort study investigates the relation between socioeconomic position and prognostic markers in 6234 persons included in a national clinical database in 2000-2008, Denmark. Several measures of individual socioeconomic position were achieved from Statistics Denmark. The risk of being diagnosed with advanced disease, as expressed by the six prognostic markers (Ann Arbor stage III or IV, more than one extranodal lesion, elevated serum lactate dehydrogenase (LDH), performance status of two or more, presence of B symptoms and International Prognostic Index (IPI) of two or more), increased with decreasing level of education, in patients living alone, and in men. For instance, a significant decrease in the odds of being diagnosed with elevated LDH (p=0.02), high performance status (p=0.004), high IPI score (p=0.004) and B symptoms (p=0.02) was seen with higher level of education, whereas high stage of disease was significantly less likely in the higher educated (odds ratio [OR]=0.85 (0.74-0.99)). The difference in risk seemed not to be mediated by differences in histological subgroups reflecting aggressiveness of disease among the social groups. One of the most likely mechanisms of the social difference is longer delay in those with low socioeconomic position. The findings of social inequality in prognostic markers in non-Hodgkin lymphoma (NHL) patients could already be implemented in the clinical practice if general practitioners (GP's) and physicians on hospitals paid special attention to patients with low educational level and unspecific symptoms.
