Upcoming Datasets

Publication schedule

The majority of ICCR datasets scheduled to be developed will be in response to updates of the World Health Organization (WHO) Classification of Tumours or applicable staging system. However, additional datasets are scheduled where there are specific needs to be addressed and resources available.

Digestive Tract – new datasets

In synchrony with updates to the WHO Classification of Digestive System Tumours, the ICCR has developed five new datasets as follows:

• Carcinoma of the appendix UNDER REVIEW POST CONSULTATION
• Carcinoma of the gallbladder UNDER REVIEW POST CONSULTATION
• Liver metastasis resection UNDER REVIEW POST CONSULTATION
• Squamous cell carcinoma of the anus – local excision specimen UNDER REVIEW POST CONSULTATION
• Squamous cell carcinoma of the anus – abdominoperineal excision specimen UNDER REVIEW POST CONSULTATION

Open consultation has closed. We anticipate the datasets will be published around mid 2026.

Haematolymphoid

In synchrony with updates to the WHO Classification of Haematolymphoid Tumours, the ICCR has developed three new datasets as follows:

• Lymphoid malignancies
• Myeloid and mixed or ambiguous lineage haematopoetic neoplasms
• Plasma cell neoplasms

Open consultation is expected in the second quarter of 2026. We anticipate the datasets will be published in the third quarter of 2026.

Skin

In synchrony with updates to the WHO Classification of Skin Tumours, the ICCR has developed a new dataset for invasive melanoma in the post neoadjuvant setting.

Open consultation is expected in the second quarter of 2026. We anticipate the dataset will be published in the third quarter of 2026.

Neuroendocrine Tumours

In synchrony with updates to the WHO Classification of Endocrine and Neuroendocrine Tumours and the WHO Classification of Digestive System Tumours, the ICCR has developed a new dataset for neuroendocrine tumours (including pancreas, luminal gut and unknown primary site).

Open consultation is expected in mid 2026. We anticipate the dataset will be published later in 2026.

Ophthalmic

In synchrony with updates to the WHO Classification of Eye and Orbit Tumours, the ICCR has commenced development of two new datasets as follows:

• Uveal melanoma
• Ocular retinoblastoma

Open consultation is expected later in 2026. We anticipate the datasets will be published in the first half of 2027.

Digestive Tract – updates

In synchrony with updates to the WHO Classification of Digestive System Tumours, the ICCR has commenced updates to eight existing datasets and development of one new dataset as follows:

• Carcinoma of the exocrine pancreas (update of 1st edition)
• Carcinoma of the oesophagus (update of 3rd edition)
• Endoscopic resection of the oesophagus and oesophagogastric junction (update of 3rd edition)
• Carcinoma of the stomach (update of 3rd edition)
• Endoscopic resection of the stomach (update of 3rd edition)
• Colorectal cancer (update of 1st edition)
• Colorectal excisional biopsy (polypectomy) specimen (update of 1st edition)
• Intrahepatic cholangiocarcinoma, perihilar cholangiocarcinoma and hepatocellular carcinoma (update of 2nd edition)
• Liver biopsy

Breast

In synchrony with updates to the WHO Classification of Breast Tumours, the ICCR will soon commence updates to four existing datasets and development of one new dataset as follows:

• Invasive carcinoma of the breast (update of 2nd edition)
• Invasive carcinoma of the breast in the setting of neoadjuvant therapy (update of 2nd edition)
• Ductal carcinoma in situ, variants of lobular carcinoma in situ and low grade lesions (update of 1st edition)
• Surgically removed lymph nodes for breast tumours (update of 1st edition)
• Phyllodes tumour of the breast

All ICCR datasets that include TNM staging have been updated to the 8th edition. Rollout of the 9th edition TNM staging to ICCR datasets has commenced.
