Additional immunochemical markers were performed based on clinical details and cytomorphology, wherever indicated. RESULTS: The mean age of the patients was 56. The female to male ratio was 2. Cytomorphology was evaluated in all the 86 cases and IHC was used to refine the cytomorphological diagnosis. A diagnosis of adenosquamous carcinoma was suspected in five cases. One case remained "uncategorized" even after IHC. CONCLUSIONS: Immunohistochemistry (IHC) performed on the pleural fluid sample can accurately diagnose and subtype primary lung carcinoma even in cases where radiology failed to do it on your own compare these a definite lung lesion.

IHC can further help in delineating primary site in tumors of extrapulmonary origin. Remon J, Le Rhun E, Besse BLeptomeningeal carcinomatosis in non-small cell lung cancer patients: A continuing challenge in the personalized treatment era. Its incidence is increasing, reaching 3.

The prognosis remains poor despite systemic treatment, intrathecal chemotherapy, radiation therapy and personalized treatments in molecularly selected patients. However, new therapies with improved cerebral-spinal fluid penetration have been developed do it on your own compare these subgroups of molecular selected patients indicating they could be promising therapeutic options for managing leptomeningeal disease.

Systemic chemotherapy, which may be combined with intrathecal chemotherapy, remains standard treatment for lung cancer patients with leptomeningeal disease and a good-risk profile. We summarize evidence reported in the literature for managing this complication in lung cancer patients.

Based on this, we have selected potential therapeutic strategies that could be used in daily clinical practice.

Crit Rev Oncol Hematol. However, the discovery of several oncogenic driver mutations and the development of immune checkpoint inhibitors resulted in improved clinical outcomes for most patients.

Although activating KRAS mutations are the most common recurring molecular events in lung adenocarcinoma, little progress has been made during the past decades with no new agents do it on your own compare these approved for this indication. The elucidation of the underlying biology do it on your own compare these this diverse patient subgroup offers great potential and renewed hope regarding the rational development, rigorous evaluation and subsequent approval of novel targeted agents and combinations which will effectively suppress compensatory do it on your own compare these routes and the emergence of resistance, issues that have plagued previous attempts.

Here, we review in a structured manner guy la roche aspects of KRAS positive non-small cell lung cancer, including the molecular biology, distributor characteristics, the prognostic and predictive value of KRAS mutations, as well as previous and contemporary approaches towards the treatment of this elusive target.

Several gene mutations that contribute to aberrant cell proliferation have been identified in lung adenocarcinoma, happy part of NSCLC.

Various anticancer drugs that target these mutated molecules have been developed for NSCLC treatment. However, although molecularly targeted drugs are initially effective for patients, the 5-year survival rate remains low because of tumor relapse. Therefore, more effective drugs for lung cancer treatment should be developed. The hedgehog (HH) signaling pathway contributes to organ development and stem cell maintenance, and aberrant activation of this signaling pathway is observed in various cancers including lung cancer.

In lung cancer, HH signaling pathway upregulates cancer cell proliferation and maintains cancer stem cells as well as cancer-associated fibroblasts (CAFs). Furthermore, physical contact between CAFs and NSCLC cells induces HH signaling pathway activation in NSCLC cells to enhance their metastatic potential.

Therefore, HH signaling pathway inhibitors could be a useful option for lung cancer therapy.
