Lung cancer is one of the leading cancers in Hong Kong, accounting for 26.4% of cancer mortality in 2018. Approximately 80% of the lung cancers are non-small cell lung cancer (NSCLC).

Women account for a disproportionate percentage of new human immunodeficiency virus (HIV) infections in sub-Saharan Africa, comprising 59% of 18 million new adult HIV infections in 2017.
Kidney transplants are the best treatment for end-stage renal disease (ESRD), with better survival outcomes than haemodialysis or peritoneal dialysis. However, in Hong Kong as well as much of the rest of the world, there is an increasing gap between the number of patients requiring a transplant and the number of organs available.
Seasonal influenza is common between January to March, and July to August in Hong Kong. Baloxavir marboxil is the first influenza antiviral with a novel mechanism of action to be approved in almost two decades, and was registered for use in Hong Kong in February 2019.
RAS is the most frequently mutated gene family in cancers, with KRAS mutations being involved as a driver in three of the most lethal cancers – lung cancer, colorectal cancer, and pancreatic cancer. Incidence of KRAS mutations vary between ethnicity with Caucasians having a higher incidence than African-Americans or Asians. In non-small lung cancer (NSCLC), the most common KRAS mutation is G12C. In Asia, G12C mutations in particular account for 14.5% of KRAS mutations in the Chinese population. KRAS G12C was identified in 4.3% of lung cancer samples and 2.5% of colorectal cancer samples.
Aberrant RET activation has shown to be a clinical driver of tumour growth and proliferation. It is reported that 1-2% of non-small cell lung cancer patients have activating RET fusions. Clinical characteristics of these patients are generally younger (<60 years) with minimal or no smoking history, and frequent presentation with brain metastases at diagnosis of advanced disease. RET mutations are mutually exclusive with other common lung cancer genetic abberations, such as reported for KRAS, EGFR, and ALK.
The development of new targeted therapies for non-small cell lung cancer (NSCLC) in recent years has changed the standard of care for the later stages of NSCLC in specific population groups.
Non-small cell lung cancer (NSCLC) was a key feature of the American Society of Clinical Oncology (ASCO) 2019 annual meeting. This year, exciting results with neoadjuvant immunotherapy (I-O) from the LCMC3, NEOSTAR, and GECP16/03_NADIM studies as well as combinations of I-O and PARP-inhibitors with chemoradiation therapy, and more. A summary of 36 oral presentations on NSCLC, SCLC, and Mesothelioma.
