Verteporfin PDT combined with ranibizumab 0.5 mg or alone was superior to ranibizumab monotherapy in achieving complete regression of polyps in this 6-month study in patients with symptomatic macular polypoidal choroidal vasculopathy. All treatments were well tolerated over 6 months.

Practical guidance on the clinical management of PCV is proposed based on expert evaluation of current evidence.

BackgroundIdiopathic pulmonary fibrosis (IPF) is associated with fatal complications after radiotherapy (RT) for lung cancer patients; however, the role of proton therapy to reduce the incidence of life-threatening complications is unclear. Herein, we present the preliminary results of early-stage lung cancer patients having IPF and treated with RT, with a focus on the comparison between X-ray and proton therapy.MethodsFrom January 2010 to October 2017, we retrospectively reviewed the medical records of 264 patients with stage I-II non-small cell lung cancer (NSCLC) treated with definitive RT alone. Ultimately, 30 patients (11.4%) who had underlying IPF were analyzed. Among these, X-ray and proton RT were delivered to 22 and 8 patients, respectively. Treatment-related complications and survival outcomes were compared between X-ray and proton therapy.ResultsThe median follow-up duration was 11 months (range, 2 to 51 months). All living patients were followed-up at least 9 months. Treatment-related death occurred in four patients (18.2%) treated with X-ray but none with proton therapy. Most patients died within one month after the onset of pulmonary symptoms in spite of aggressive treatment. In addition, the 1-year overall survival (OS) rate in patients treated with X-ray and proton was 46.4 and 66.7%, respectively, and patients treated with proton therapy showed a tendency of better survival compared to X-ray (p = 0.081). Especially, in GAP stage II and III subgroups, patients treated with proton therapy showed significantly increased survival outcomes compared to X-ray (1-year OS rate; 50.0% versus 26.4%, p = 0.036) in univariate analysis.ConclusionsRT is associated with serious treatment-related complications in patients with IPF. Proton therapy may be helpful to reduce these acute and fatal complications.Trial registrationretrospectively registered.

Elevated NLR and PLR levels can be considered as predictors of poor pathologic response, and NLR can be considered a prognosticator in patients who underwent neoadjuvant chemoradiotherapy for locally advanced rectal cancer.

ObjectivesTo determine the risk factors for retinal microvascular impairment on optical coherence tomography angiography (OCT-A) in type 2 diabetic patients without clinical diabetic retinopathy (DR).MethodsThis retrospective and cross-sectional study enrolled 74 diabetic patients without clinically evident DR for the study group and 34 healthy subjects for the control group. OCT-A parameters were measured to determine vascular density (VD) and the foveal avascular zone (FAZ) size in the superficial and deep capillary plexuses (SCP/DCP) of the retina. Clinical data were collected on sex, age, diabetes duration, hemoglobin A1c (HbA1c), hypertension, dyslipidemia, low-density lipoprotein cholesterol (LDL-C), estimated glomerular filtration rate (eGFR) and smoking status. Multiple linear regression analyses were performed to represent the associated clinical variables with OCT-A parameters in diabetic patients.ResultsIn comparison between the study and control groups, the VD in the SCP and DCP were significantly lower in diabetic patients compared to the controls (P = 0.022 and 0.003, respectively). The FAZ size in the SCP and DCP were significantly greater in diabetic patients compared to the controls (P = 0.035 and <0.001, respectively). In age- and sex-adjusted multiple regression analyses for the diabetic patients, dyslipidemia and hypertension were negatively associated with SCP-VD (β = -0.357, P = 0.002; β = -0.239, P = 0.039, respectively). Current smoking was correlated with lower DCP-VD (β = -0.255, P = 0.043). Greater SCP-FAZ size was associated with dyslipidemia and greater LDL-C (β = 0.254, P = 0.013; β = 0.232, P = 0.029, respectively), and greater DCP-FAZ size, with lower eGFR and greater LDL-C (β = -0.355, P = 0.004; β = 0.235, P = 0.037, respectively).ConclusionsDiabetic patients without clinical DR showed lower VD and greater FAZ size in the SCP and DCP compared to healthy controls. In diabetic patients without clinical DR, dyslipidemia and/or high LDL-C were important risk factors for retinal microvascular impairment. Hypertension, current smoking and lower eGFR also contributed to microvascular impairment.

Objectives: There is no consensus on whether giving adjuvant concurrent chemoradiotherapy (CCRT) is more effective than adjuvant radiotherapy (RT) alone in patients with early stage cervical cancer and intermediate-risk factor(s). The purpose of this study was to evaluate survival difference according to adjuvant treatment in the intermediate-risk group. Methods: From 2000 to 2014, the medical records of patients with stage IB-IIA cervical cancer and a history of radical hysterectomy with pelvic lymph node dissection, followed by pelvic RT at a dose ≥40 Gy were retrospectively reviewed. Among these, 316 patients with one or more intermediate-risk factor(s) and no high-risk factors were included. The criteria defined the intermediate-risk group as those patients with any of the following intermediate-risk factors: lymphovascular space involvement, over one-half stromal invasion, or tumor size ≥4 cm. Results: The median follow-up duration was 70 months (range: 3-203 months). According to adjuvant treatment (adjuvant RT alone vs. adjuvant CCRT), the 5-year recurrence-free survival rates (90.8% vs. 88.9%, p=0.631) and 5-year overall survival rates (95.9% vs. 91.0%, p=0.287) did not show a significant difference in patients with any of the intermediate-risk factors. In multivariate analysis, a distinct survival difference according to adjuvant treatment was not found regardless of the number of risk factors. Conclusion: The present study showed that giving RT together with chemotherapy is not more effective than RT alone for stage IB-IIA cervical cancer patients with intermediate-risk factor(s).
