ReviewManagement of CNS metastases in patients with EGFR mutation-positive NSCLC.
Central nervous system (CNS) metastases are a frequent and severe complication associated with epidermal growth factor receptor (EGFR)-mutated non-small cell lung cancer (NSCLC). The first- and second-generation EGFR tyrosine kinase inhibitors (TKIs) have shown considerable efficacy in EGFR-mutated NSCLC. However, their limited potential to cross the blood-brain barrier (BBB) renders them less effective in the management of CNS metastases in NSCLC. ⋯ These data have supported osimertinib to be recognized as a "preferred" first-line treatment for EGFR-positive metastatic NSCLC by the National Comprehensive Cancer Network (NCCN). With limited treatment options available, upfront administration of osimertinib in patients with NSCLC irrespective of EGFR T790M and CNS metastases may improve the overall response rate and potentially reduce the adverse effects of radiotherapy. Our review focuses on the management of EGFR-mutated NSCLC CNS metastases in the context of recent NCCN guidelines.

ReviewRevisiting adjuvant ovarian suppression in premenopausal breast cancer patients.
Adjuvant ovarian suppression, on addition to chemotherapy, reduces the risk of breast cancer in pre-menopausal women after surgery and adjuvant hormonal therapy. Suppression of Ovarian Function Trial (SOFT) and Tamoxifen and Exemestane Trial (TEXT) showed greater benefit with exemestane in high risk females in comparison to Tamoxifen. Ovarian Function Suppression (OFS) and exemestane became the standard of care, with 30% patients experiencing grade 3 and more side effects. ⋯ Updated analysis of TEXT AND SOFT showed better survival benefit with OFS plus Tamoxifen as compared to OFS plus exemestane. Overall survival is a better end point. Should preference be given to Tamoxifen over exemestane? Further research is required to get the final answer.

Use of interventional bronchoscopic treatment in small cell lung cancer.
Small cell lung cancer (SCLC) constitutes 15%-25% of all lung cancers. Their treatment approach is different from nonsmall cell lung cancer. Central airway obstruction develops at the time of diagnosis or eventually at some time as the disease progress. Quick relief of symptoms with chemotherapy will cause to postpone interventional bronchoscopy which divest patient from benefits of this procedure. There is a few data about the use of interventional bronchoscopy in SCLC. ⋯ Multimodal interventional bronchoscopic methods seem to be a last option but may be useful in the management of advanced airway obstruction in the setting of SCLC. The choice of modality may be chosen depending upon individual patient characteristics as appropriate.

Retrospective comparison of standard and escalated doses of radiotherapy in newly diagnosed glioblastoma patients treated with concurrent and adjuvant temozolomide.
To compare the efficacies of standard dose-(SDRT) and escalated dose radiotherapy (EDRT) in newly diagnosed glioblastoma (GBM) with concurrent and adjuvant temozolomide (TMZ). ⋯ Although the current median OS of 22 months of the EDRT group is promising, no statistically significant survival advantage for EDRT was observed even in the presence of TMZ. Randomized studies with larger population sizes and available genetic markers are warranted to conclude more reliably on the fate of EDRT plus TMZ.

Barriers affecting uptake of cervical cancer screening in low and middle income countries: A systematic review.
Cervical cancer is the second-most common cancer among women in the developing world and approximately 500,000 cases are diagnosed each year. In developed countries, cervical cancer (CCa) accounts for only 3.6% of newly diagnosed cancers. ⋯ There is a need of policies advancement of CCa screening programs by focusing on aspects of accessibility, affordability, CCa education, and the necessity of screening to improve screening uptake to control the CCa morbidity and mortality rate in L and MIC's.
