Psoriasis is a chronic multisystem, autoimmune and inflammatory dermatological condition. It usually persists throughout one’s lifetime, and spontaneous remission is rarely seen. As per the World Health Organization (WHO), the global prevalence of psoriasis is about 0.09%–11.4%.1 Psoriasis may be linked to other serious diseases, such as depression, psoriatic arthritis...

I read with great interest the study conducted by Fong et al. published in this issue of Annals, which evaluated psychological symptoms and health-related quality of life (HRQOL) among a cohort of 143 young adult survivors of childhood cancer in Singapore.1 Almost 1 in 4 survivors demonstrated significant psychological...

Advancements in technology and cancer treatments have improved childhood cancer survival rates, with up to 85% surviving 5 years or more.1 The Malaysia-Singapore Leukaemia Study Group reported an improvement in overall 5-year survival for the past 20 years in Singapore, from 69% to 91% for acute lymphoblastic leukaemia, which...

Dear Editor, The Eastern Cooperative Oncology Group (ECOG) is a commonly used performance status (PS) scale in oncology. It influences cancer treatment decisions and clinical trial recruitment. However, there can be significant inter-rater variability in ECOG-PS scoring, due to subjectivity in human scoring and innate cognitive biases.1,2 We propose that...

Randomised controlled trials (RCTs) and systematic reviews are the most reliable ways of relaying information on the most effective treatments for our patients in clinical practice. The careful design of trials to minimise the possibility of bias ensures that findings are internally valid, but this may threaten their clinical...

Alcohol flushing syndrome (AFS) is characterised by intense facial flushing, often accompanied by palpitations, headache and nausea shortly after the consumption of alcohol. This phenomenon occurs in up to 46% of East Asians and to a much lesser extent Caucasians, due to the accumulation of acetaldehyde, a metabolic byproduct...

Globally, alcohol consumption is responsible for an estimated 3 million deaths annually and contributes to over 740,000 new cancer cases each year.1 Acetaldehyde, a byproduct of alcohol metabolism, has been designated as first-class carcinogens by the International Agency for Research on Cancer.2 In East Asian countries such as China,...

Breast cancer-related lymphedema (BCRL) is a chronic progressive pathological condition of the lymphatic system that can lead to significant impact on the quality of life after breast cancer treatment.1 It is characterised by swelling and accumulation of protein-rich fluid in body tissues, leading to pain, tightness, skin changes such...

Breast cancer mortality has declined steadily over the years with breast cancer screening, and improvement in diagnostic and therapeutic regimens. Despite cancer survivors living longer, breast cancer-related lymphedema (BCRL) is a significant complication after major breast surgery that can impact quality of life adversely. The incidence of BCRL reported...

Osteoporotic vertebral fractures (OVFs) are the most prevalent type of fragility fractures, affecting 25% of adults in their early 70s and 43% of those over the age of 80.1,2 Following an OVF, persistence of the vertebral deformity may lead to spinal kyphosis, which is associated with chronic lower back...

Osteoporosis and cancer share a complex relationship, with each condition influencing the progression and outcomes of the other.1 Multiple factors, such as chemo- and hormonal therapies, and the direct invasion of bone tissue by malignant cells contribute to the accelerated bone loss seen in cancer patients.1 Various anti-osteoporosis drugs,...

Amyloidosis refers to disorders characterised by the deposition of insoluble amyloid fibrils, which are pathogenic,1 resulting in organ dysfunction. Amyloidoses differ in the protein precursor undergoing aggregation and downstream target organs implicated. Consequently, clinical manifestations are varied, from localised amyloidosis in Alzheimer’s disease, to systemic amyloidosis such as immunoglobulin...

Multiple myeloma (MM) is a haematological malignancy characterised by abnormal accumulation of malignant plasma cells and is associated with anaemia, renal impairment, hypercalcemia and bone lesions. A sensitive method to detect bone lesions is crucial as it could determine the decision to start treatment. In this era, the International...

In this issue of the Annals, Tan et al. on behalf of Singapore Myeloma Study Group presented the consensus guidelines on light chain (AL) amyloidosis.1 This is an encouraging effort as AL amyloidosis is a rare disease, with diagnostic and therapeutic challenges.  A comprehensive review examining its pathophysiology, diagnostic...

Dear Editor, Re. Surgical margins assessment reduces re-excision rates in breast-conserving surgery I read with interest the article by Woon et al. published in a recent issue of the Annals on the reduction of re-excision rates with the use of intraoperative frozen section (FS) analysis.1 This certainly has the potential...

Dear Editor, The first use of surgical robotics started in the domain of orthopaedic and urological surgery. However, it was the initial concept of using a robot in performing remote damage control surgeries on the battlefield that sparked the commercialisation of robotic surgical technology for use in operating rooms.1 The...

Prostate cancer is the fifth most common cancer in Asian men, and with its rising incidence, is emerging as a health priority in Asia.1 Across Asian countries, age-standardised incidence rates (ASIRs) of prostate cancer range from 0.9 to 56.1 per 100,000 population, with the second highest ASIR reported in...

Compared with other solid tumours, patients with metastatic prostate cancer typically have better survival in the range of years.1 The long survival translates to a high prevalence, and thus, a large number of men living with prostate cancer. Singapore has one of the highest age-standardised incidence rates of prostate...

The spread of the SARS-CoV-2 virus has led to the ongoing worldwide COVID-19 pandemic. Initial studies have reported an increased vulnerability of patients with solid and haematological malignancies to SARS-CoV-2 infections.1,2 Global efforts to combat SARS-CoV-2 led to the unprecedented rapid development of multiple vaccines, with reported efficacies of...

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and its corresponding coronavirus disease (COVID-19) was first reported as a cluster of pneumonia cases in Wuhan, China, on 31 December 20191 and led to an unprecedented pandemic in modern times. It quickly overwhelmed healthcare systems around the world, and rendered...

Breast cancer is a major public health concern and a leading cause of cancer death among women worldwide, including Singapore.1 According to the 2018 Singapore Cancer Registry report, breast cancer has been consistently ranked as a leading cancer (29.3% of all cancers in Singapore) among women in Singapore for...

As only 5–10% of thyroid nodules harbour malignancy, fine-needle aspiration (FNA) is important in triaging nodules requiring surgical excision from nodules that may be observed.1,2 This approach allows risk stratification that can reduce the rate of benign lesion removal by diagnostic lobectomies3 and its associated postoperative morbidity.4 However, thyroid...

Cancer is a pervasive global problem with growing healthcare utilisation and costs.1-3 This situation is similar in Singapore where cancer incidence is on the rise and accounts for nearly 30% of total population mortality.4,5 Singapore data suggests that cancer patients accounted for 13% of total healthcare costs in 2016,...

Public hospital occupancy rates and resource utilisation in Singapore are perennially high. In the last 2 years of the COVID-19 pandemic, there has been a significant strain on public healthcare systems to balance the demands of the pandemic and usual medical care. There is little literature detailing emergency department (ED)...

Colorectal cancer (CRC) is the one of most common cancers worldwide. Metastatic disease occurs in approximately half of all CRC patients, in either synchronous or metachronous presentations.1 These patients form a heterogenous group that vary in presentation, disease progression and treatment options. Advancements in surgery and chemotherapy have revolutionised the...
