Abstract. Data concerning bevacizumab plus pemetrexed plus carboplatin as first-line treatment for patients with non-squamous non-small cell lung cancer (NSCLC) with or without brain metastases (BM) are lacking. The present study analyzed the efficacy and safety of this combination as induction therapy, followed by maintenance therapy with bevacizumab plus pemetrexed in non-squamous NSCLC patients with or without BM. Treatment-naïve patients with advanced non-squamous NSCLC and an Eastern Cooperative Oncology Group performance status score of 0-2 were eligible. Treatment consisted of carboplatin (area under the curve of 5), pemetrexed (500 mg/m 2 ) and bevacizumab (15 mg/kg) every 3 weeks for 6 cycles. Responders and patients with stable disease received maintenance therapy with bevacizumab plus pemetrexed until disease progression, which was evaluated every 3 cycles, or unacceptable toxicity. Kaplan-Meier median progression-free survival (PFS) and overall survival (OS) times were the primary endpoints, and safety was the secondary endpoint. In total, 39 patients, aged 44-78 years (median, 60 years), were treated; 11 (28.2%) of whom presented with BM. The majority of patients (56.4%) completed 6 cycles of induction therapy, and 26 patients continued on to maintenance therapy. The median PFS time was 8.2 months [95% confidence interval (CI), 7.05-9.35] and the median OS time was 14.0 months (95% CI,). Median PFS and OS times did not differ significantly between patients with or without BM (log rank (Mantel-Cox): PFS, P=0.748 and OS, P=0.447). The majority of patients (76.9%) did not experience adverse events during treatment. Overall, bevacizumab plus pemetrexed plus carboplatin as induction therapy, followed by bevacizumab plus pemetrexed as maintenance therapy was effective and well tolerated in advanced NSCLC, whether brain metastases were present or not. IntroductionLung cancer is the leading cause of cancer-related mortality worldwide (1). The age-standardized (world) lung cancer mortality rate in Greece shows that one in two cancer-related mortalities in men are caused by lung cancer (50%); the figure for women is much lower at 6.3% (2). The majority of patients (70%) exhibit advanced disease at the time of diagnosis (3), and 5 years after diagnosis, only 16.6% of patients remain alive (4).Research in the field of more effective management of lung cancer is clearly worthwhile, with the goal of increasing survival while maintaining quality of life, and promising advances have been made. The current standard of care for advanced non-small cell lung cancer (NSCLC) is cytotoxic combination chemotherapy with a platinum compound (carboplatin or cisplatin) and one other agent, such as pemetrexed, vinorelbine, paclitaxel, gemcitabine or docetaxel (5,6). Therapy is usually administered for a maximum of 6 cycles unless the disease progresses or there is no response (6).Pemetrexed inhibits thymidylate synthase and other folate-dependent enzymes involved in the metabolism and synthesis of DNA precursors.

Preoperative ECX/ECF chemotherapy for patients with resectable esophagogastric adenocarcinoma was associated with relatively high incidence of TEEs. However, only arTEEs affected patient survival outcomes.
BackgroundMalignant bowel obstruction (MBO) is a common cause of morbidity and mortality in women diagnosed with ovarian cancer. Earlier detection of MBO may improve patient outcomes. There are currently no screening tools to assist detection.AimWe report a screening questionnaire that can be used to detect MBO, and how the severity score for key clinical symptoms correlate with radiological evidence of MBO from ovarian cancer.DesignA case–control study in which patients with relapsed, metastatic ovarian cancer were asked to answer 10 questions related to key clinical symptoms associated with intestinal obstruction. The study group included women with CT-confirmed MBO, whereas the control group had no evidence of MBO. Patients scored each question according to severity from 1 (least severe) to 5 (most severe).Setting/participantsBetween 1 June and 31 December 2016, 37 women completed the screening questionnaire.ResultsPatients in the study group (n=17) reported significantly higher (ie, more severe) scores for abdominal pain, nausea, vomiting and constipation. In contrast, differences in severity scores between groups did not differ significantly in response to questions regarding abdominal swelling, borborygmi, diarrhoea or loss of appetite. All patients in the study group more frequently stated that their symptoms had deteriorated within the 2 months prior to completing the questionnaire.ConclusionHere we report the key clinical symptoms associated with radiologically-confirmed MBO in relapsed, metastatic ovarian cancer. We recommend healthcare practitioners focus on these specific symptoms during patient consultations in order to improve risk stratification of MBO.
The prognosis of patients with gastroesophageal junction (GOJ) adenocarcinoma depends mainly on the clinical staging, as described by the new AJCC8 (American Joint Committee on Cancer 8th edition). Evidence suggests that peripheral blood neutrophil-to-lymphocyte ratio (NLR) may be of prognostic significance in patients with upper gastrointestinal cancers. We examined the prognostic significance of NLR in the era of the new AJCC8 staging system. In this single-centre cohort study, retrospective data on patients with operable GOJ adenocarcinoma treated with perioperative chemotherapy were analysed. The prognostic significance of baseline NLR in combination with AJCC8 clinical staging and other patient characteristics was examined for both time-to-progression (TTP) and overall survival (OS). Of 316 patients, 245 (77.5%) underwent radical surgery. Fifty-one patients (16.2%) developed unresectable disease due to early disease progression. NLR was the only baseline factor independently associated with the development of early disease progression. AJCC8 clinical staging was significantly associated with TTP and OS. In addition, NLR ≥ 3 was predictive of poorer TTP (p = 0.001) and OS (p = 0.002), confirmed in multivariate Cox-regression analysis. NLR ≥ 3 was prognostic, especially in patients with clinical stage III for TTP (p = 0.006) and OS (p = 0.025) and in patients with clinical stage IVA for OS (p = 0.017). NLR significantly improved the prognostic classification of patients by different AJCC8 clinical stages, with a c-index improved from 0.554 to 0.592 (p < 0.001). NLR was confirmed to be an independent prognostic factor in this cohort and could be used in combination with AJCC8 clinical staging to improve the baseline prognostic stratification of patients with newly diagnosed resectable GOJ adenocarcinoma.
