Association of insurance status and ethnicity with cancer stage at diagnosis for 12 cancer sites: a retrospective analysis.
Individuals in the USA without private medical insurance are less likely to have access to medical care or participate in cancer screening programmes than those with private medical insurance. Smaller regional studies in the USA suggest that uninsured and Medicaid-insured individuals are more likely to present with advanced-stage cancer than privately insured patients; however, this finding has not been assessed using contemporary, national-level data. Furthermore, patients with cancer from ethnic minorities are more likely to be uninsured or Medicaid-insured than non-Hispanic white people. Separating the effects on stage of cancer at diagnosis associated with these two types of patient characteristics can be difficult. ⋯ In this US-based analysis, uninsured and Medicaid-insured patients, and those from ethnic minorities, had substantially increased risks of presenting with advanced-stage cancers at diagnosis. Although many factors other than insurance status also affect the quality of care received, adequate insurance is a crucial factor for receiving appropriate cancer screening and timely access to medical care.

Randomized Controlled Trial Comparative StudySix versus eight cycles of bi-weekly CHOP-14 with or without rituximab in elderly patients with aggressive CD20+ B-cell lymphomas: a randomised controlled trial (RICOVER-60).
Cyclophosphamide, doxorubicin, vincristine, and prednisolone (CHOP) is used to treat patients with non-Hodgkin lymphoma. Interval decrease from 3 weeks of treatment (CHOP-21) to 2 weeks (CHOP-14), and addition of rituximab to CHOP-21 (R-CHOP-21) has been shown to improve outcome in elderly patients with diffuse large B-cell lymphoma (DLBCL). This randomised trial assessed whether six or eight cycles of R-CHOP-14 can improve outcome of these patients compared with six or eight cycles of CHOP-14. ⋯ Six cycles of R-CHOP-14 significantly improved event-free, progression-free, and overall survival over six cycles of CHOP-14 treatment. Response-adapted addition of chemotherapy beyond six cycles, though widely practiced, is not justified. Of the four regimens assessed in this study, six cycles of R-CHOP-14 is the preferred treatment for elderly patients, with which other approaches should be compared.

ReviewCancer registration in developing countries: luxury or necessity?
Differences in culture and resources between low-income and high-income countries have resulted in unequal rights to health. In the past few decades, developing countries have had an increase in chronic-disease burden, including cancer. ⋯ To fight this burden, the extent of the cancer must be known so that programmes for cancer control can be planned efficiently, not only to implement standards of care but also to define prevention strategies. In this Review, we advocate the need for availability of cancer data and discuss potential opportunities for hospital-based and population-based cancer registries to collaborate in providing these data in low-income countries.
