Background: Mammography screening programs (MSP) have shown that breast cancer can be detected at an earlier stage enabling less invasive treatment and leading to a better survival rate. The considerable numbers of interval breast cancer (IBC) and the additional examinations required, the majority of which turn out not to be cancer, are critically assessed.

Objective: In recent years companies and universities have used machine learning (ML) to develop powerful algorithms that demonstrate astonishing abilities to read mammograms.

Introduction: The clinical course of prostate cancer (PCa) is highly variable, ranging from indolent behavior to rapid metastatic progression. The Gleason score is widely accepted as the primary histologic assessment tool with significant prognostic value. However, additional biomarkers are required to better stratify patients, particularly those at intermediate risk.

Hereditary breast cancers, mainly due to BRCA1 and BRCA2 mutations, account for only 5-10% of this disease. The threshold for genetic testing is a 10% likelihood of detecting a mutation, as determined by validated models such as BOADICEA and Manchester Scoring System. A 90-95% reduction in breast cancer risk can be achieved with bilateral risk-reducing mastectomy in unaffected BRCA mutation carriers.

Metastasis is the primary cause of death in prostate cancer (PCa) patients. Small nucleolar RNAs (snoRNAs) have long been considered "housekeeping" genes with no relevance for cancer biology. Emerging evidence has challenged this assumption, suggesting that snoRNA expression is frequently modulated during cancer progression.

Teaching farmers integrated pest management (IPM) in farmer field schools (FFS) has led to reduced pesticide use and safer handling. This article evaluates the long-term impact of training farmers on IPM and the diffusion of knowledge from trained farmers to neighboring farmers, a subject of importance to justify training costs and to promote a healthy and sustainable agriculture. Training on IPM of farmers took place from 2002 to 2004 in their villages in La Paz County, Bolivia, whereas dissemination of knowledge from trained farmer to neighboring farmer took place until 2009.

Background: Fluorouracil-based adjuvant chemotherapy in gastric cancer has been reported to be effective by several meta-analyses. Perioperative chemotherapy in locally advanced resectable gastric cancer (RGC) has been reported improving survival by two large randomized trials and recent meta-analyses but the role of neoadjuvant chemotherapy and optimal regimen remains to be determined. We compared a neoadjuvant with adjuvant docetaxel-based regimen in a prospective randomized phase III trial, of which we present the 10-year follow-up data.

Background: The role of epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKI) in the treatment of patients with advanced non-small cell lung cancer (NSCLC) and unknown EGFR mutation status has recently been questioned.

Patients And Methods: We conducted a retrospective study of patients with unknown EGFR mutation status and long-term response (LTR) to gefitinib in the Swiss Iressa expanded access program (EAP). We assessed patient characteristics, and performed Sanger sequencing and next generation sequencing on archived tumor tissue.

Introduction: This phase II trial evaluated the efficacy and safety of the epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor, gefitinib, in combination with first-line chemotherapy in advanced urothelial cancer.

Methods: Chemotherapy-naïve patients with advanced or metastatic urothelial carcinoma were randomized 1:1:1 to receive six cycles of chemotherapy (gemcitabine 1,250 mg/m2 on days 1 and 8, and cisplatin 70 mg/m2 on day 1 of every cycle) concomitantly with gefitinib 250 mg/day (arm A); or with sequential gefitinib (arm B); or alone (arm C). The primary endpoint was the time to progression (TTP).

Article Synopsis
  • * PCAT18 is specifically overexpressed in prostate cancer tissues compared to other cancers and can be detected in plasma, correlating with disease progression from localized to metastatic PCa.
  • * Silencing PCAT18 significantly reduces cancer cell growth, migration, and invasion without affecting non-cancerous cells, highlighting its potential as a therapeutic target for metastatic PCa.

With the continuing increase of median life expectancy of important segments of the world's population, cancer incidence, as well as cancer related morbidity and mortality, are constantly increasing, especially for developing countries and for breast and prostate cancer, the predominant gender-associated cancer types. In addition to continuing, with more and more expensive efforts to develop new and more effective cancer treatments, it is health-politically and medico-professionally important to realise that only successful approaches to primary cancer prevention of major and frequent cancer types will be able to change this socially and economically unfavourably outlook. It is therefore encouraging to see that primary (or pharmacologic, interventional) cancer prevention programs have been successfully developed over the past decade for individuals at elevated risk for breast and prostate cancer on the basis of several scientifically well-conducted, prospective chemoprevention trials, mainly with synthetic anti-hormones (anti-estrogens and anti-androgens) in the USA, in Europe and Australia.

Randomized phase III studies compare new treatments with standard therapy according to defined guidelines and legal rules. Large international randomized phase III studies are some of the most complex and expensive medical experiments. The results of such trials will decide about the future of new drugs and are the basis of evidence-based medicine and the development of clinical guidelines.

Background: Prostate cancer is the most common type of cancer in men, however, therapeutic options are limited. 50-90% of hormone-refractory prostate cancer cells show an overexpression of epidermal growth factor receptor (EGFR), which may contribute to uncontrolled proliferation and resistance to chemotherapy. In vitro, gefitinib, an orally administered tyrosine kinase inhibitor, has shown a significant increase in antitumor activity when combined with chemotherapy.
