BACKGROUND/AIM: This study explored the prognostic significance of the neutrophil-to-lymphocyte ratio (NLR) and use of antibiotics in advanced esophageal squamous cell carcinoma (ESCC) patients receiving immune checkpoint inhibitors (ICIs). PATIENTS AND METHODS: Patients were enrolled from two referral centers in Taiwan. Clinical benefit was defined as complete response, partial response, or a stable disease for ≥6 months via Response Evaluation Criteria In Solid Tumors 1.1. Clinicopathological factors' impact on overall survival (OS) and progression-free survival (PFS) was analyzed via Cox proportional hazards model. RESULTS: Forty-nine patients were enrolled. The median PFS and OS were 1.8 and 6.1 months, respectively. The median NLR at baseline was 6.40, and 21 patients received antibiotics. Both high NLR and use of antibiotics were associated with inferior PFS (p=0.028 and p<0.001, respectively) and OS (p<0.001 and p<0.001, respectively) in multivariate analysis. CONCLUSION: High NLR and use of antibiotics were associated with inferior survival in advanced ESCC patients receiving ICIs.

The effects of cardiopulmonary resuscitation (CPR) on patients with advanced cancer remain to be elucidated. We identified a cohort of patients with stage-IV cancer who received in-hospital CPR from the Taiwan Cancer Registry and National Health Insurance claims database, along with a matched cohort without cancer who also received in-hospital CPR. The main outcomes were post-discharge survival and in-hospital mortality. In total, 3,446 stage-IV cancer patients who underwent in-hospital CPR after cancer diagnosis were identified during January 2009-June 2014. A vast majority of the patients did not survive to discharge (n = 2,854, 82.8%). The median post-discharge survival was 22 days; 10.1% (n = 60; 1.7% of all patients) of the hospital survivors received anticancer therapy after discharge. We created 1:1 age-, sex-, Charlson comorbidity index (CCI)-, and year of CPR-matched noncancer and stage-IV cancer cohorts (n = 3,425 in both; in-hospital mortality rate = 82.1% and 82.8%, respectively). Regression analysis showed that the stage-IV cancer cohort had shorter post-discharge survival than did the noncancer cohort. The outcome of patients with advanced cancer was poor. Even among the survivors, post-discharge survival was short, with only few patients receiving further anticancer therapy.

We evaluated the prognostic significance of immunologic inhibitory biomarkers in head and neck squamous cell carcinoma (HNSCC) patients undergoing definitive chemoradiotherapy (CRT). Thirty patients were prospectively enrolled. Plasma levels of soluble MHC class I polypeptide-related sequence A (sMICA) and transforming growth factor-ß1 (TGF-ß1) were measured before and 2 weeks after CRT. The median follow-up was 32.9 months (range: 12.4-40.6 months). The pre-treatment sMICA (p < 0.001) and TGF-ß1 (p < 0.001) levels were significantly increased in HNSCC patients, compared to healthy controls. In HNSCC patients, the median pre-CRT and post-CRT sMICA levels were 43.1 pg/mL and 65.3 pg/mL, respectively, while the median pre-CRT and post-CRT TGF-ß1 levels were 57.7 ng/mL and 36.0 ng/mL, respectively. After CRT, 19 patients (63.3%) exhibited persistently elevated sMICA, six patients (20.0%) exhibited persistently elevated TGF-ß1, and five patients (16.7%) exhibited persistently elevated sMICA and TGF-ß1. Patients with persistently elevated sMICA and TGF-ß1 after CRT experienced an earlier tumor progression (p = 0.030), and poor overall survival (p = 0.010). Our results suggest that HNSCC patients who exhibit persistently elevated sMICA and TGF-ß1 levels after CRT are at higher risk of tumor progression or death.

BACKGROUND: The association of extended lymph node (LN) dissection with improved outcomes in patients with locally advanced esophageal squamous cell carcinoma (ESCC) who received preoperative chemoradiotherapy (CRT) followed by surgery is debatable. PATIENTS AND METHODS: We reviewed data from patients with esophageal cancer enrolled in three phase II clinical trials of preoperative paclitaxel and cisplatin-based CRT during 2000-2012. Patients with ESCC who underwent planned esophagectomy were enrolled. The number of resected LNs and other clinicopathological factors were analyzed regarding their impact on progression-free (PFS) and overall (OS) survival using Cox proportional hazards model. RESULTS: In total, 139 patients were included. The median PFS and OS were 24.4 and 31.8 months, respectively. The median number of resected and positive LNs were 19 (range=2-96) and 0 (range=0-9), respectively. The mean number of positive LNs did not differ significantly among quartile groups of total resected LNs (quartile 1: 2-12, 2: 13-19, 3: 20-29, and 4: 30-96). The resected LN number analyzed as dichotomies divided by the median or as continuous variables was not associated with PFS or OS. However, in an exploratory analysis, patients of quartiles 2 and 3 had longer PFS and OS than those with quartiles of 1 and 4 in multivariate analysis (p=0.019 and 0.005, respectively). CONCLUSION: Although extensive LN dissection was not associated with improved survival, resection of 13-29 LNs was associated with improved survival in patients with locally advanced ESCC receiving preoperative paclitaxel and cisplatin-based CRT.

BACKGROUND: Many studies have shown that type 2 diabetes mellitus (DM) increases the risk for several types of cancer but not cervical cancer (CC). Although DM and insulin-like growth factor 1 have preclinical and clinical implications for CC, less is known about the prognostic impact of DM on patients with early stage CC. PATIENTS AND METHODS: We used the nationwide Taiwan Cancer Registry database to collect the characteristics of stage I-IIA cervical cancer patients diagnosed between 2004 and 2008. DM and other comorbidities were retrieved from the National Health Insurance database. Cervical cancer-specific survival (CSS) and overall survival (OS) times of patients according to DM status were estimated using the Kaplan-Meier method. We used a Cox proportional hazards model to calculate adjusted hazard ratios (HRs) for the effects of DM and other risk factors on mortality. RESULTS: A total of 2,946 patients had primary stage I-IIA CC and received curative treatments, and 284 (9.6%) had DM. The 5-year CSS and OS rates for patients with DM were significantly lower than those without DM (CSS: 85.4% vs. 91.5%; OS: 73.9% vs. 87.9%). After adjusting for clinicopathologic variables and comorbidities, DM remained an independent unfavorable prognostic factor for CSS (adjusted HR: 1.46) and OS (adjusted HR: 1.55). CONCLUSION: In Asian patients with early cervical cancer, DM is an independent unfavorable prognostic factor influencing both OS and CSS, even after curative treatments. IMPLICATIONS FOR PRACTICE: Type 2 diabetes mellitus (DM) increases the incidence of several types of cancer but not cervical cancer (CC); however, less is known about the impact of DM on patients who already have CC. This study suggests that DM may increase the risk of cancer recurrence and death for early stage CC patients, even after curative treatments. Incorporating DM control should be considered part of the continuum of care for early stage CC patients, and close surveillance during routine follow-up in this population is recommended.

The prognosis of advanced gastric cancer (AGC) remains poor despite therapeutic advances in recent decades. Several recent positive phase III trials established the efficacy of second-line chemotherapy for metastatic gastric cancer in prolonging overall survival. However, malnutrition and poor performance of AGC in late stages usually preclude such patients from intensive treatment. Many targeted-therapies failed to show a significant survival benefit in AGC, but have regained attention after the positive result of ramucirumab was announced last year. Among all targeted agents, only trastuzumab, a monoclonal antibody against Human epidermal growth factor receptor-2 (HER2) protein, has been proven as having survival benefit by addition to first-line chemotherapy. Herein we reported a patient who benefited from adding trastuzumab to the same second-line combination chemotherapy (paclitaxel, 5-fluorouracil, and leucovorin) upon progression of bulky liver metastases. At least five months of progression-free survival were achieved without any additional toxicity. We also reviewed literature of molecularly-targeted therapy for chemotherapy-refractory gastric cancer, including several large phase III trials (REGARD, GRANITE-1, EXPAND, and REAL-3) published in 2013-2014.
