Assessing a modified-AJCC TNM staging system in the New South Wales Cancer Registry, Australia.

Background: In 2017, the New South Wales Cancer Registry (NSWCR) participated in a project, supported by Cancer Australia, aiming to provide national stage data for melanoma, prostate, colorectal, breast, and lung cancers diagnosed in 2011. Simplified business rules based on the American Joint Committee for Cancer (AJCC) Tumour-Node-Metastasis (TNM) stage were applied to obtain Registry-Derived (RD) stage, defined as the best estimate of TNM stage at diagnosis using routine notifications available within cancer registries. RD-stage was compared with Degree of Spread (DoS), which has been recorded for all applicable cancers in NSWCR at a population-based level since 1972, and a summary AJCC-TNM stage group, which has been collected variably since 2006.

Estimated risk of progression of lentigo maligna to lentigo maligna melanoma.

Little is known about the risk of progression of lentigo maligna to lentigo maligna melanoma. We determine the annual risk of progression of lentigo maligna to lentigo maligna melanoma by analysing a prospective population-based survey of recently diagnosed anterior (visible in a mirror) head and neck lentigo malignas and lentigo maligna melanomas. Six hundred eighty-two consecutive patients aged 18-80 years with non-recurrent lentigo maligna or lentigo maligna melanoma, diagnosed between 1 July 2015 and 20 April 2016, were identified from pathology notifications to the New South Wales Cancer Registry (Australia) and sent survey questionnaires soon after diagnosis (median 4.

Cancer-related hospitalisations and 'unknown' stage prostate cancer: a population-based record linkage study.

Objectives: To identify reasons for prostate cancer stage being recorded as 'unknown' in Australia's largest population-based cancer registry.

Design: Prospective population-based cohort.

Setting: New South Wales (NSW) is the most populous state in Australia, with almost one third of the total national population.

Characteristics of cases with unknown stage prostate cancer in a population-based cancer registry.

Background: The New South Wales Central Cancer Registry (NSW CCR) is the only population-based cancer registry in Australia that has routinely collected summary stage at diagnosis since its inception in 1972. However, a large proportion of prostate cancer cases have "unknown" stage recorded by the registry. We investigated the characteristics of prostate cancer cases with "unknown" stage recorded by the NSW CCR, and examined survival for this group.

Competing risk analysis of mortality from invasive cutaneous melanoma in New South Wales: a population-based study, 1988-2007.

Objective: Accurate estimates of risk of death from melanoma, based on the most recent information, are desirable, especially if secular improvements in survival have occurred. This study aims to investigate prognostic factors and temporal changes in mortality from primary invasive cutaneous melanoma (CM) and to predict cumulative probabilities of death from CM.

Methods: Cases of CM from the NSW Central Cancer Registry (NSWCCR) diagnosed in 1988-2007 were analysed.

Neonatal inflammation and primary afferent terminal plasticity in the rat dorsal horn.

Abnormal or excessive activity related to pain and injury in early life may alter normal synaptic development and lead to changes in somatosensory processing. The aim of the current study was to define the critical factors that determine long-term plasticity in spinal cord afferent terminals following neonatal inflammation. Hindpaw inflammation was produced in neonatal rat pups with 5 or 25 microl 2% carrageenan, and 5 or 25 microl complete Freund's adjuvant (CFA).

High-molecular-weight tropomyosins localize to the contractile rings of dividing CNS cells but are absent from malignant pediatric and adult CNS tumors.

Tropomyosin has been implicated in the control of actin filament dynamics during cell migration, morphogenesis, and cytokinesis. In order to gain insight into the role of tropomyosins in cell division, we examined their expression in developing and neoplastic brain tissue. We found that the high-molecular-weight tropomyosins are downregulated at birth, which correlates with glial cell differentiation and withdrawal of most cells from the cell cycle.
