Outcome Measures

Primary Outcomes (3)

  • Overall survival

    Survival after first hospitalization due to cancer

    first hospitalization (starting from 01/01/2009 [WIdO] or 01/01/2006 [CCR]), up to 31/12/2017

  • 1- and 5-year survival

    1- and 5-year survival after first hospitalization due to cancer

    first hospitalization (starting from 01/01/2009 [WIdO] or 01/01/2006 [CCR]) with 1 or 5-year follow-up, respectively

  • 30-day mortality

    30-day mortality after first hospitalization due to cancer

    first hospitalization (starting from 01/01/2009 [WIdO] or 01/01/2006 [CCR]) with 30 days follow-up

Secondary Outcomes (11)

  • 2-, 3-, 4-year survival

    first hospitalization (starting from 01/01/2009 [WIdO] or 01/01/2006 [CCR]) with 2,3, or 4-year follow-up, respectively

  • Recurrence-free survival

    cancer diagnosis (starting from 01/01/2009 [WIdO] or 01/01/2006 [CCR]), up to 31/12/2017

  • Cumulative recurrence rate

    cancer diagnosis (starting from 01/01/2009 [WIdO] or 01/01/2006 [CCR]), up to 31/12/2017

  • Complications due to surgery

    date of initial cancer surgery with entity-specific follow-up

  • Successive resection

    second resection within three months of initial cancer surgery

  • +6 more secondary outcomes

Study Arms (2)

Intervention

Cancer patients who have undergone substantial parts of inpatient treatment in a certified cancer centre.

Other: Oncological certification

Control

Cancer patients who have not undergone inpatient treatment in a certified cancer centre.

Interventions

Oncological certification encompasses a variety of criteria such as treatment according to the clinical guidelines, staffing, technical infrastructure, minimum caseloads, and multidisciplinary care.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

German residents with continuous insurance of one of the AOK funds 2006-2017 and patients recorded in one of the participating cancer registries Dresden, Erfurt, Regensburg and Berlin-Brandenburg 2006-2017

You may qualify if:

  • first hospitalization due to diagnosis of colorectal cancer, pancreatic cancer, breast cancer, gynecologic tumors, lung cancer, prostate cancer, head and neck tumors, or neuro-oncological tumors 2009-2017 \[WIdO\]
  • hospitalization due to primary diagnosis of colorectal cancer, pancreatic cancer, breast cancer, gynecologic tumors, lung cancer, prostate cancer, head and neck tumors, or neuro-oncological tumors 2006-2017 \[CCR\]

You may not qualify if:

  • prevalent diagnosis of colorectal cancer, pancreatic cancer, breast cancer, gynecologic tumors, lung cancer, prostate cancer, head and neck tumors, or neuro-oncological tumors 2006-2017
  • exception: outpatient cancer diagnosis up to 12 months prior to first hospitalization is not regarded as prevalent
