Diagnoses spanning moderately dysplastic nevi to early stage invasive melanoma were neither reproducible nor accurate, according to the results of a large study of pathologists in the US.
Authors of the study, published by The BMJ, have called for efforts to improve clinical practice such as using a standardised classification system, acknowledging uncertainty in pathology reports, and developing tools such as molecular markers to support pathologists’ visual assessments. They also urged doctors to share with their patients that the practice of medicine can be inherently uncertain.

This review details recent advances in the diagnosis and treatment of prostate cancer which have improved the ability to stratify patients by risk and allowed clinicians to recommend therapy based on cancer prognosis and patient preference.
Prostate cancer is the most common cancer diagnosis made in men with more than 160 000 new cases each year in the United States. Although it often has an indolent course, prostate cancer remains the third-leading cause of cancer death in men.
When prostate cancer is suspected, tissue biopsy remains the standard of care for diagnosis. However, the identification and characterization of the disease have become increasingly precise through improved risk stratification and advances in magnetic resonance and functional imaging, as well as from the emergence of biomarkers. Multiple management options now exist for men diagnosed with prostate cancer. Active surveillance (the serial monitoring for disease progression with the intent to cure) appears to be safe and has become the preferred approach for men with less-aggressive prostate cancer, particularly those with a prostate-specific antigen level of less than 10 ng/mL and Gleason score 3 + 3 tumors. Surgery and radiation continue to be curative treatments for localized disease but have adverse effects such as urinary symptoms and sexual dysfunction that can negatively affect quality of life. For metastatic disease, chemotherapy as initial treatment now appears to extend survival compared with androgen deprivation therapy alone. New vaccines, hormonal therapeutics, and bone-targeting agents have demonstrated efficacy in men with metastatic prostate cancer resistant to traditional hormonal therapy.
Advances in the diagnosis and treatment of prostate cancer have improved the ability to stratify patients by risk and allowed clinicians to recommend therapy based on cancer prognosis and patient preference. Initial treatment with chemotherapy can improve survival compared with androgen deprivation therapy. Abiraterone, enzalutamide, and other agents can improve outcomes in men with metastatic prostate cancer resistant to traditional hormonal therapy.
Cancer and cancer treatment coincide with substantial negative physical, psychological and psychosocial problems | BMC Cancer
Background: Physical activity (PA) can positively affect the negative effects of cancer and cancer treatment and thereby increase quality of life in CPS. Nevertheless, only a minority of CPS meet PA guidelines. We developed the OncoActive (OncoActief in Dutch) intervention: a computer-tailored PA program to stimulate PA in prostate and colorectal CPS, because to our knowledge there are only a few PA interventions for these specific cancer types in the Netherlands
Discussion: Using the Intervention Mapping protocol resulted in a systematically adapted, theory and evidence-based intervention providing tailored PA advice to prostate and colorectal CPS. If the intervention turns out to be effective in increasing PA, as evaluated in a RCT, possibilities for nationwide implementation and extension to other cancer types will be explored.

Liver cancer is a growing global public health problem. Ultrasonography is an imaging tool widely used for the early diagnosis of liver cancer | BMJ Open
Image shows low magnification micrograph of hepatocellular carcinoma the most common form of primary liver cancer.
Objective: The effect of ultrasonography surveillance (US) on the survival of patients with liver cancer is unknown. Therefore, this study examined the association between survival and US frequency during the 2 years preceding patients’ liver cancer diagnosis.
Methods: This population-based longitudinal study was conducted in Taiwan, a region with high liver cancer incidence, by using the National Health Insurance Research Database. We compared survival between patients who received US three times or more (≥3 group) and less than three times (<3 group) during the 2 years preceding their liver cancer diagnosis, and identified the predictors for the ≥3 group.
Results: This study enrolled 4621 patients with liver cancer who had died between 1997 and 2010. The median survival rate was higher in the ≥3 group (1.42 years) than in the <3 group (0.51 years). Five-year survival probability was also significantly higher in the ≥3 group (14.4%) than in the <3 group (7.7%). The multivariate logistic regression results showed that the three most common positive predictors for receiving three or more US sessions were indications of viral hepatitis, gallbladder diseases and kidney–urinary–bladder diseases; the most common negative predictors for receiving three or more US sessions were male sex and indications of abdominal pain.
Conclusion: Patients with liver cancer who received US three times or more during the 2 years preceding their liver cancer diagnosis exhibited a higher 5-year survival probability.

To support return to work (RTW) among cancer patients, a multidisciplinary rehabilitation programme was developed which combined occupational counselling with a supervised physical exercise programme during chemotherapy | BMJ Open
Objectives: The aim was to investigate RTW rates of cancer patients and to evaluate changes in work-related quality of life and physical outcomes.
Conclusions: RTW rates of cancer patients were high after completion of the multidisciplinary rehabilitation programme. A multidisciplinary rehabilitation programme which combines occupational counselling with a supervised physical exercise programme is likely to result in RTW, reduced fatigue and increased importance of work, work ability, and quality of life.
