Gastric cancer is the fourth most common cancer and the second leading cause of cancer-related deaths worldwide. Gastric cancer is characterized by high levels of invasion and metastasis. Increasing attention is being focused on discovering molecular markers for the diagnosis of gastric cancer and for predicting its prognosis. The objective of the present study was to evaluate Nurr1 expression in gastric cancer and to assess its correlation with clinicopathological parameters and prognosis in gastric cancer patients. ⋯ The Nurr1 protein may be useful as a marker of recurrence, metastasis, and poor prognosis following curative resection in patients with gastric cancer.

Compared to pure small cell lung cancer (SCLC), combined small cell lung cancer (C-SCLC) has its own characteristics. High neutrophil to lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR) have been shown to be related to poor prognosis in several types of tumors. The aim of this study was to explore the prognosis value of NLR and PLR in patients with C-SCLC. ⋯ High pretreatment NLR (≥4.15) is a potential useful indicator for C-SCLC recurrence and predicts a poor long-term prognosis for C-SCLC, which should be considered in defining the prognosis with other well-known prognosticators in C-SCLC patients.

To determine whether the specific genotype of exon 19 deletion has a better survival outcome than that of exon 21 substitution in advanced lung adenocarcinoma with EGFR mutant patients that were treated with EGFR-TKIs as second-line therapy after first-line chemotherapy. ⋯ Compared with L858R mutation, the genotype of exon 19 deletion had a better survival outcome in terms of PFS and OS in patients with advanced lung adenocarcinoma treated with EGFR-TKIs as second-line therapy after first-line chemotherapy.

Despite that basal cell carcinoma (BCC) is curative in the vast majority of cases, some patients are at high risk of recurrence and, in a few patients, lesions can progress to a point unsuitable for local therapy and prognosis is quite poor. The aim of the present work is to review clinical and pathologic characteristics as well as classical and new treatment options for high-risk, metastatic and locally advanced BCC. ⋯ Treatment of these patients is challenging and need an individualized and highly specialized approach. The treatment of locally advanced BCC, in which surgery or radiotherapy is unfeasible, inappropriate or contraindicated, and metastatic BCC has changed with new Hedgehog pathway inhibitors of which vismodegib is the first drug approved by FDA and EMA.

Practice Guideline
Clinical guideline SEOM: cancer of unknown primary site.
Cancer of unknown primary site is a histologically confirmed cancer which is manifested in advanced stage, with no identifiable primary site after the use of standard diagnostic procedures. Patients are initially placed into one of categories based upon the examination of the initial biopsy: adenocarcinoma, squamous cell carcinoma, neuroendocrine carcinoma and poorly differentiated carcinoma. Appropriate patient management requires an understanding of several clinicopathologic features that help to identify several subsets of patients with more responsive tumors.
