Research ready Lung Data
Research ready lung data
Overview
This data dictionary describes the contents of the research ready lung cancer data set. This data set is made up of all Queensland non-small cell lung cancer (NSCLC) diagnoses between 2000 and 2019. The fields have been arranged in four categories as follows:
- Demographic,
- Clinical,
- Treatment, and
- Administrative
and a dataset sample is provided containing 10 example records. For detailed reference tables containing ICD Codes for clinical data items such as Primary Site, Morphology and Procedure codes, please see Reference Sets.
Population-wide data on stage is available for the first time, with the most recent years 2017-2019 containing TNM stage information. Multi-modal treatment data (Surgery, Radiation therapy, Intravenous Systemic Therapy) is available for patients who underwent treatment for their diagnosis of lung cancer, along with details of known MDT presentations.
All of the data within this collection comes from the Queensland Oncology Repository (QOR), a cancer patient database developed and maintained by the Queensland Cancer Control Analysis Team (QCCAT; Queensland Health) to support Queensland’s cancer control, safety, and quality assurance initiatives. QOR consolidates cancer patient information for the state and contains data on diagnoses and deaths, surgery, chemotherapy, and radiotherapy. For more information, visit our website.

Clinical
The clinical fields contained in this dataset include information about the cancer diagnosed. This includes date of diagnosis, the clinical features of the tumour such as size, morphology, nodal status and the presence of metastases. For the first time, clinical stage is included in this data. Full staging information is available only for patients diagnosed 2017-2019, although Stage IV patients have been identified from 2000-onwards. This data is comprehensive and has been obtained from clinical audits conducted by clinicians and coders, leading to the development of automated algorithms used on prospective data to glean stage routinely for new diagnoses.

SOCIOECONOMIC STATUS
Socioeconomic status is based on the Socio-Economic Indexes for Areas (SEIFA), a census-based measure of social and economic well-being developed by the Australian Bureau of Statistics (ABS) and aggregated at the level of Statistical Local Areas (SLA).
The ABS use SEIFA scores to rank regions into ten groups (deciles) numbered one to ten, with one being the most disadvantaged and ten being the most affluent group.
This ranking is useful at the national level, but the number of people in each decile often becomes too small for meaningful comparisons when applied to a subset of the population.
For this reason, this document further aggregates SEIFA deciles into 3 socioeconomic groups.
| Socioeconomic status decile | Group | Percentage of population |
|---|---|---|
| 1-2 | Disadvantaged | 0.2 |
| 3-8 | Middle | 0.6 |
| 9-10 | Affluent | 0.2 |
Frequently Asked Questions (FAQ)
What data is included in the Research Ready Dataset (RRD)?
This dataset contains records for all persons diagnosed with Non-Small Cell Lung Cancer (NSCLC) in Queensland between 2000 and 2019. Demographic data such as sex, age-group, location/remoteness of residence is included.
Is the data anonymised?
Yes. No names or addresses will be included in the data extracts. Unique identifiers will be attached to each person included in the file.
Does this dataset contain information on treatments the individual received?
Yes. Data on the following modes of treatment are included in the dataset: surgery (major resections), radiation therapy (RT), intra-venous systemic therapy (IVST)
Are there gaps in the data?
Treatment data is available for the duration of the 20-yr period. Complete surgical data is available for the full timespan. Radiation therapy data sources were enhanced in 2007 and data from 2007-2019 has greater coverage. Similarly, chemotherapy sources such as iPharmacy and CHARM were progressively added, leading to full coverage from 2009. Chemotherapy data is limited to Intra-venous systemic therapy (IVST) only.
Staging data capture is limited to Stage IV only for 2000 to 2016 and has been inferred by the presence of clinical records indicating metastases. From 2017 onwards, complete 8th edition staging data has been inferred using TNM staging approaches via clinical data reviewed by specialist coders.
