Because of the rapid growth rate there may be an advantage to emergently beginning chemotherapy as soon as SCLC diagnosis is made. Methods: All SCLC patients evaluated at Cooper University Hospital from January 2011 to September 2014 were reviewed. Multiple clinical factors were analyzed including timing between diagnosis and start of chemotherapy. Results: A total of 75 patients were analyzed. On univariate analysis there was a survival detriment to early initiation of chemotherapy. With multivariate analysis the difference in survival disappeared. With logistic regression, the only variable that was related to overall survival was stage (extensive versus limited). We did not find any subset that benefited from early initiation of chemotherapy. Conclusions: Mortality and cumulative survival time were not improved by early initiation of chemotherapy for any patient subset. Only stage at diagnosis was predictive for mortality and cumulative survival. Our data appears to show that urgency in starting chemotherapy has little bearing on survival in patients diagnosed with SCLC. The data suggest that there is no detriment to a non-urgent start time for chemotherapy. time, symptomatic disease, and early development of metastatic disease [1,2]. The cellular proliferation rate is much higher in comparison to other types of lung cancer, which has contributed tothe view of newly diagnosed SCLC as an “oncologic emergency”. Some oncologists will urge the start of chemotherapy as soon as possible (sometimes within 24 hours of diagnosis) given the potential for aggressive growth and metastasis. Similarly, some institutions will keep a patient with newly diagnosed lung cancer admitted to the hospital until final pathology is available so that in the event that the final diagnosis is SCLC chemotherapy can be initiated immediately as an in-patient. The theoretical rationale for emergent start of chemotherapy is based on the perceived rapid growth rate for SCLC. Since the tumor has such rapid growth potential, earlier chemotherapy start time may allow for an increase in cure rate for limited stage patients and provide improved disease control in extensive stage patients. While there may be a theoretical benefit to early initiation of chemotherapy, there is also a downside. Emergent initiation of therapy may overwhelm patients who haven’t had time to properly process their disease status (including potentially compromising the integrity of informed consent), strain hospital systems with the costs of inpatient chemotherapy and delayed discharge, and interfere with proper disease staging.

The unique physical and chemical properties of carboranes make their use attractive in drug development. In several instances, the inclusion of carboranes into a drug structure has increased the agent’s binding affinity, potency, or bioavailability. The purpose of this review is to highlight applications of carboranes to the medicinal chemistry of cancer.

The closo-carboranes are both air and moisture stable and are known to possess “superhydrophobicity.” Their high partition coefficient values are known to surpass common bioisosteres such as aryl, cycloalkyl, and adamantyl groups [5]. Moreover, their high stability and low toxicity towards cells make them interesting compounds for therapeutic applications [2]. The interactions between carborane pharmacophores and the active sites of biological targets are often stronger than those of the aryl, cycloakyl, or adamantyl pharmacophore counterparts. Several studies have been performed in an attempt to elucidate the underlying mechanism behind these interactions. In addition to the three dimensional shape and hydrophobicity which results in more points of interaction with the active site, the carborane cage can form dihydrogen bonds. The formation and characteristics of the dihydrogen bonds were explored by Fanfrlik et al. through the use of molecular dynamic simulations between carboranes and various amino and nucleic acids [28]. Dihydrogen bonding, also named proton-hydride bonding, typically occurs between a positively charged hydrogen atom of a proton donor AH (A=N, O, S, C, halogen) and an MH proton acceptor (M=boron, alkali metal, or transition metal). In the case of carboranes and biological molecules these bonds form between NH--HB, CH--HB, and SH--HB. Such bonds are calculated to exhibit strong stabilization energies between 6.1 to 7.6 kcal mol-1, compared with 1 to 5 kcal mol-1 for typical biomolecular hydrogen bond strengths, and H--H distances between 1.7 to 2.2 Å [28]. These interactions can potentially be used to improve the binding of carboranes over the more conventional pharmacophores containing aromatic groups such as aryl, or cycloakyl, or adamantyl. The successful design and implementation of a pharmacophore requires a careful study of the drug candidate’s pharmacokinetics. In cancer therapy, the agent’s biodistribution is an especially important characteristic","PeriodicalId":13873,"journal":{"name":"International journal of cancer and clinical research","volume":"28 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73828623","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods: A comparative case study compared data of two cross-sectional studies. The historical group (HG) was treated in 2013, the implementation group (IG) in 2016. The HG received a questionnaire, which resulted in implementation of the following items in our practice, expansion of the BCT brochure and photo book, incorporation of the Harvard and Numeric Rating scale. The IG received the same questionnaire, with the addition of nine more questions concerning specific implementation aspects. Results: The HG contained 76 patients (age 41-86), versus 57 in the IG (age 40-84). Although additional information tools were implemented, no significant enhancement of IG patient satisfaction could be demonstrated. Nevertheless, the need for information appeared significantly greater (p < 0.001) in the IG. Conclusion: The need for information about cosmesis was greater in the IG, possibly due to increased attention paid by professionals. Furthermore, it is difficult to improve an information program concerning cosmetic consequences of BCT, despite the implementation of better tools.

Treatment of acoustic neuromas targets to achieve local control while preserving hearing without comprimising cranial nerve functionality. In this context, radiosurgery in the form of Stereotactic Radiosurgery (SRS) or fractionated stereotactic radiotherapy (FSRT) offer viable therapeutic options for effective management. Multimodality imaging has gained utmost priority for improved target defnition for radiosurgery. In this study, we assessed the utility of Magnetic Resonance Imaging (MRI) for target volume definition for acoustic neuroma radiosurgery. Methods and materials: Twenty patients treated with radiosurgery for acoustic neuroma at our institution were included. Radiosurgery target definition was performed by using CT simulation images only or by using fused T1 gadolinium-enhanced MR images acquired within 1 week before treatment day. A comparative evaluation was made including volumetric analysis of target volumes. Results: Target volume definition based on CT-only imaging and CT-MR fusion based imaging were comparatively evaluated for 20 patients receiving SRS for acoustic neuroma at our institution. Mean target volumes were 5.7 cc (range: 2.1-13.9 cc) and 6.2 cc (range: 2.3-14.1 cc) with CT-only imaging and CT-MR fusion based imaging, respectively.

Our aim was to assess whether the combined presence of reduction of the diameter of the largest tumor mass and of the CA125 level predict response to Neoadjuvant Chemotherapy (NACT). Material and methods: Clinicopathological data were abstracted from medical records of consecutive OvC and PPC patients who received paclitaxel + carboplatin NACT and underwent IDS. Computed tomography (CT) images before NACT and prior to IDS where compared. Response to NACT prior to IDS was determined according to the combined presence of two parameters: 1. Reduction in the greatest diameter of the largest CT tumor mass by 50% and 2. Reduction of the CA 125 level to ≤ 75 U/ml. No response was determined when both of these parameters where not observed. Results: Of 50 study group patients 10 (20.0%) had a response and 40 (80.0%) had no response to NACT. Optimal debulking (< 1 cm) was achieved in all responders and in 92.5% of nonresponders. The median progression free survival was similar in responders and nonresponders. The Overall Survival (OS) was 62.2% in responders and 22.6% in nonresponders (p = 0.40).
