Abstract
OBJECTIVES To evaluate the value of high-risk HPV (HR HPV) testing in screening and post-treatment follow-up of high-grade squamous intraepithelial cervical lesions (HSIL). METHODS A systematic review of the literature from 2000 to 2019 was conducted including the following keywords: "human papilloma virus", "HPV testing", "cervical squamous intraepithelial lesion", "cervical cancer". RESULT Numerous recent randomized studies and meta-analyzes have concordant results in favor of HR HPV superiority over cervical smear in the screening and post-treatment monitoring of HSIL. In screening, the sensitivity of the HR HPV tests is 63% to 98% whereas that of the cervical smear is only 38% to 65% for the detection of HSIL+ (HSIL and invasive cancers). A negative HR HPV test is associated with less than 5% risk of LIEHG+at 6 years. In addition, after removal of a LIEHG, HR HPV tests have a sensitivity>90% and specificity>80% to predict treatment failure. After surgicale exision, a negative HR HPV test is associated with a risk of failure<2% (negative predictive value of 98%), and 12-25% if it is positive. CONCLUSIONS HR HPV tests are effective, allowing early detection of LIEHG+ identification of low-risk women in case of negative test, and a prediction of the risk of failure after treatment.

Abstract
BACKGROUND There is scarce data available about epidermal growth factor receptor (EGFR) mutations other than common exon 19 deletions and exon 21 (L858R) mutations. PATIENTS AND METHODS EGFR exon 18 and/or exon 20 mutations were collected from 10 117 non-small-cell lung cancer (NSCLC) samples analysed at 15 French National Cancer Institute (INCa)-platforms of the ERMETIC-IFCT network. RESULTS Between 2008 and 2011, 1047 (10%) samples were EGFR-mutated, 102 (10%) with rare mutations: 41 (4%) in exon 18, 49 (5%) in exon 20, and 12 (1%) with other EGFR mutations. Exon 20 mutations were related to never-smoker status, when compared with exon 18 mutations (P < 0.001). Median overall survival (OS) of metastatic disease was 21 months [95% confidence interval (CI) 12-24], worse in smokers than in non-smoker patients with exon 20 mutations (12 versus 21 months; hazard ratio [HR] for death 0.27, 95% CI 0.08-0.87, P = 0.03). Under EGFR-tyrosine kinase inhibitors (TKIs), median OS was 14 months (95% CI 6-21); disease control rate was better for complex mutations (6 of 7, 86%) than for single mutations (16 of 40, 40%) (P = 0.03). CONCLUSIONS Rare EGFR-mutated NSCLCs are heterogeneous, with resistance of distal exon 20 insertions and better sensitivity of exon 18 or complex mutations to EGFR-TKIs, probably requiring individual assessment.

Abstract
This article introduces smart sample holders for optical microscopy. Their purpose is to allow the absolute determination of the position of the observed zone with respect to the sample holder itself and with a high accuracy. It becomes then straightforward to find a given zone of interest by positioning coarsely the microscope slide to the same position coordinates. Furthermore images recorded during different observation sessions; i.e. for slightly different positions; can be processed numerically in order to superimpose them with a high accuracy. Thus the slight deviations of the microscope slide position and orientation due to the different observations are compensated numerically and a perfect superimposition of the recorded images is performed. Then accurate site-by-site image comparisons become possible even for images recorded during different observation sessions and over a long period of time. The subpixel capability of the proposed method is demonstrated and those smart microscope slides constitute a new tool for live cell experiment. In practise, an encoded geometrical pattern used as position reference is inserted in a plane parallel to the surface receiving the tissue section or sample. Then the transition of the focus position from the tissue section to the position reference requires only a vertical adjustment and does not affect the lateral coordinates of observation. The numeric processing of the image of the position reference pattern allows the retrieval of the lateral coordinates that are also used for the tissue section image. Thus each image is recorded with a set of position coordinates that defines accurately the position of the observed area with respect to the sample holder itself.
