ReviewNew-onset diabetes: a potential clue to the early diagnosis of pancreatic cancer.
Pancreatic cancer has a dismal prognosis because cancer-specific symptoms occur only at an advanced stage. If the cancer is to be discovered early, screening will need to be done in asymptomatic individuals. Because the incidence of pancreatic cancer is low, screening for asymptomatic cancer in the general population is not feasible; therefore, screening will need to be restricted to people at high risk of this disease. ⋯ Recognition of new-onset diabetes as an early manifestation of pancreatic cancer could lead to the diagnosis of asymptomatic, early-stage pancreatic cancer. However, primary type-2 diabetes is common in the general population and pancreatic cancer is relatively uncommon, and the two forms of diabetes are clinically indistinguishable. The success of a strategy using new-onset hyperglycaemia and diabetes as a screening tool to identify people with a high likelihood of having asymptomatic pancreatic cancer will depend largely on our ability to differentiate pancreatic-cancer-associated diabetes from the more common type-2 diabetes by use of a (serological) biomarker.

Randomized Controlled TrialEfficacy and safety of sorafenib in patients in the Asia-Pacific region with advanced hepatocellular carcinoma: a phase III randomised, double-blind, placebo-controlled trial.
Most cases of hepatocellular carcinoma occur in the Asia-Pacific region, where chronic hepatitis B infection is an important aetiological factor. Assessing the efficacy and safety of new therapeutic options in an Asia-Pacific population is thus important. We did a multinational phase III, randomised, double-blind, placebo-controlled trial to assess the efficacy and safety of sorafenib in patients from the Asia-Pacific region with advanced (unresectable or metastatic) hepatocellular carcinoma. ⋯ Sorafenib is effective for the treatment of advanced hepatocellular carcinoma in patients from the Asia-Pacific region, and is well tolerated. Taken together with data from the Sorafenib Hepatocellular Carcinoma Assessment Randomised Protocol (SHARP) trial, sorafenib seems to be an appropriate option for the treatment of advanced hepatocellular carcinoma.

Randomized Controlled Trial Comparative StudySurvival after laparoscopic surgery versus open surgery for colon cancer: long-term outcome of a randomised clinical trial.
Laparoscopic surgery for colon cancer has been proven safe, but debate continues over whether the available long-term survival data justify implementation of laparoscopic techniques in surgery for colon cancer. The aim of the COlon cancer Laparoscopic or Open Resection (COLOR) trial was to compare 3-year disease-free survival and overall survival after laparoscopic and open resection of solitary colon cancer. ⋯ Our trial could not rule out a difference in disease-free survival at 3 years in favour of open colectomy because the upper limit of the 95% CI for the difference just exceeded the predetermined non-inferiority boundary of 7%. However, the difference in disease-free survival between groups was small and, we believe, clinically acceptable, justifying the implementation of laparoscopic surgery into daily practice. Further studies should address whether laparoscopic surgery is superior to open surgery in this setting.

ReviewEffects of comorbidity on screening and early diagnosis of cancer in elderly people.
There is currently little data showing that older adults can derive benefit from cancer screening. Advancing age is associated with an increasing prevalence of cancer and other chronic conditions, or comorbidity, and questions remain about the interactions between comorbidity and cancer screening in the elderly population. In this Review, we assess the available evidence on the effects of comorbidity on cancer screening in elderly individuals. ⋯ Decisions on cancer screening in older adults should be based on an appropriate assessment of each individual's health status and life expectancy, the benefits and harms of screening procedures, and patient preferences. We suggest that Comprehensive Geriatric Assessment might be a necessary step to identify candidates for cancer screening in the elderly population. Specific clinical trials should be done to improve the evidence and show the effectiveness and cost-effectiveness of cancer screening in older adults.
