Colorectal cancer is a carcinoma arising from the luminal surface of the colon.
It is the 2nd most common cancer in women and third most common cancer in male worldwide. It commonly arises from adenomatous polyps.
It is strongly linked to age with 83% occurring in people ≥60 years old.
Rectal cancer is defined as cancerous lesions located within 12 cm of the anal verge.
Paediatric-onset inflammatory bowel disease (IBD) carries a doubled risk of developing cancer later in life, with skin, lymphoid, and gastrointestinal tumours of a particular concern, a study has found. The risk is higher in males and independent of IBD subtype and medical treatment.
Patients with any subtypes of polyps had a greater risk of developing colorectal cancer (CRC) than the general population in a largely screening-naive Swedish cohort, indicating that CRC risk is not limited to just those with advanced histology, reveals a large registry-based study.
In addition to survival benefit, the BEACON CRC trial has now shown that a targeted drug combination of encorafenib plus cetuximab with or without binimetinib led to longer maintenance of quality of life (QoL) for patients with BRAF V600E metastatic colorectal cancer (mCRC) compared with standard chemotherapy.
The plant alkaloid berberine effectively reduces the risk of recurrent colorectal adenoma in individuals who had recently undergone polypectomy, according to a study — thus providing a potential option for chemoprevention of adenoma.
Primary tumour resection (PTR) prior to a chemotherapy regimen does not improve survival outcomes in patients with asymptomatic unresectable stage IV colorectal cancer (CRC), according to the phase III JCOG1007* trial.
Individuals with ulcerative colitis (UC) appear to be at an elevated risk of developing and dying from colorectal cancer (CRC), despite often presenting at an earlier stage of CRC than those without UC, a recent study showed.
A personalized surveillance strategy according to risk stratification appears to be safe in the management of patients with serrated polyposis syndrome, reducing colonoscopy burden without risking an increased colorectal cancer incidence, a recent study has shown.
Reducing the dose of regorafenib did little to affect the overall tolerability of the drug in patients with metastatic colorectal cancer (mCRC), according to the phase II REARRANGE* trial presented at ESMO GI 2019.
Switching from efavirenz/emtricitabine/tenofovir disoproxil fumarate (EFV/FTC/TDF) to the new bictegravir/ emtricitabine/tenofovir alafenamide (BIC/FTC/TAF) regimen maintained high rates of virological suppression in adults who are living with HIV*, according to a study presented at AIDS 2020.
Pre-exposure prophylaxis (PrEP) containing either long-acting injectable cabotegravir (CAB) or tenofovir/emtricitabine (TDF/FTC) is safe and effective for transgender women (TGW) and cisgender men who have sex with men (MSM), but CAB results in a much lower HIV incidence compared to TDF/FTC, results of the HIV Prevention Trials Network (HPTN) 083 have shown.
Monthly prophylaxis with the fixed-dose combination of naphthoquine-azithromycin (NQAZ) is well tolerated and confers significant protection against infection with Plasmodium parasites among individuals residing in malaria-endemic areas in Southeast Asia, as shown in the results of a phase III trial.
