Introduction: Diagnosing non-small cell lung cancer on biopsy/cellblock samples by morphology may be demanding. As sparing material for molecular testing is mandatory, a minimalist immunohistochemistry (IHC)-based diagnostic approach is warranted by means of novel, reliable, and easy-to-assess biomarkers. Methods: Forty-six consecutive biopsy/cellblock samples and the corresponding resection specimens (as the gold standard for morphology and IHC) from 30 adenocarcinomas (AD), 10 squamous carcinomas (SQC), 5 adenosquamous carcinomas (ADSQC), and 1 sarcomatoid carcinoma (SC) were IHC-evaluated for p40 [corresponding to nontransactivating ΔNp63 isoforms] and thyroid transcription factor-1 (TTF1) by semiquantitative assessment. For p40, also immunodecoration intensity was taken into account and dichotomized as strong or low. Results: Nonrandom and overlapping distributions of the relevant markers were found in biopsy/cellblock and surgical specimens, which closely correlated with each other and the diverse tumor categories, with no differences in area under curve-receiver-operating-characteristic curves for each marker between any two samples, including p40 and p63. Diagnostic combinations were p40-/TTF1+ or TTF1- for AD (where p40 was negative, apart from 5/30 AD showing at the best 1-2% tumor cells with low intensity); p40+/TTF1- (p40 strong and by far higher than 50%) for SQC; and p40+/TTF1- or p40+/TTF1- (p40 strong and less than 50%) for ADSQC. The single SC case was p40-/TTF1-, suggesting glandular lineage. Practically, 41/46 (89%) tumors were correctly classified by IHC on small samples, including 30 AD, 10 SQC, 1/5 ADSQC, and no SC. Underdiagnosis of ADSQC was actually because of sampling error of biopsies/cellblocks rather than insufficient biomarker robustness, whereas underdiagnosis of SC was really because of the failure of either marker to highlight epithelialmesenchymal transition. Conclusions: This minimalist IHC-based model of p40 and TTF1 on biopsy/cellblock samples was effective to correctly subtype most cases of lung cancer.

Optimum management of the N0 neck is unresolved in oral cancer. Sentinel node biopsy (SNB) can reliably detect microscopic lymph node metastasis. The object of this study was to establish whether the technique was both reliable in staging the N0 neck and a safe oncological procedure in patients with early-stage oral squamous cell carcinoma.An European Organisation for Research and Treatment of Cancer-approved prospective, observational study commenced in 2005. Fourteen European centres recruited 415 patients with radiologically staged T1-T2N0 squamous cell carcinoma. SNB was undertaken with an average of 3.2 nodes removed per patient. Patients were excluded if the sentinel node (SN) could not be identified. A positive SN led to a neck dissection within 3 weeks. Analysis was performed at 3-year follow-up.An SN was found in 99.5% of cases. Positive SNs were found in 23% (94 in 415). A false-negative result occurred in 14% (15 in 109) of patients, of whom eight were subsequently rescued by salvage therapy. Recurrence after a positive SNB and subsequent neck dissection occurred in 22 patients, of which 16 (73%) were in the neck and just six patients were rescued. Only minor complications (3%) were reported following SNB. Disease-specific survival was 94%. The sensitivity of SNB was 86% and the negative predictive value 95%.These data show that SNB is a reliable and safe oncological technique for staging the clinically N0 neck in patients with T1 and T2 oral cancer.

Background: We performed a retrospective analysis of data from a phase II study evaluating sorafenib in patients with advanced hepatocellular carcinoma (HCC) to assess differences in safety and efficacy based on Child-Pugh (CP) status (A/B). Methods: Patients received sorafenib 400 mg PO bid. We analyzed safety, pharmacokinetic (PK), and efficacy data in the two CP groups. Results: Ninety-eight patients were CP A; 38 were CP B, with a median duration of therapy of 4 and 1.8 months, respectively. Grade 3/4 adverse events in the CP A and B groups, respectively, included hyperbilirubinemia (14% and 53%), ascites (3% and 5%), and encephalopathy (3% and 13%). Median overall survival (OS) in the CP A group was 9.5 months, compared with 3.2 months in the CP B population. Responses were limited in both groups. AUC and Cmax values were comparable between the two groups. Conclusions: Due to the lack of randomization against placebo or no therapy in this study, it is unclear if the more frequent worsening of liver cirrhosis and outcome of CP B patients are drug related or due to disease progression, or both. As expected, outcome was poorer in patients with CP B than in those with CP A cirrhosis. The hyperbilirubinemia seen in both groups may be at least partly related to inhibition of UGT1A1 by sorafenib. PK profiles were similar in the two groups. More data are needed to confirm and more fully understand the safety and efficacy of sorafenib in patients with advanced HCC and CP B cirrhosis. © 2011 by International Society of Gastrointestinal Oncology.

The aim of this multicentre study is to report the clinical experiences of all patients undergoing transcatheter aortic valve implantation (TAVI) with a balloon-expandable device in Italy.The Italian Transcatheter balloon-Expandable valve Registry (ITER) is a real-world registry that includes patients who have undergone TAVI with the Sapien (Edwards Lifesciences, Irvine, CA, USA) bioprosthesis in Italy since it became available in clinical practice. From 2007 to 2012, 1904 patients were enrolled to undergo TAVI in 33 Italian centres. Outcomes were classified according to the updated Valve Academic Research Consortium (VARC-2) definitions. A multivariable analysis was performed to identify independent predictors of all-cause mortality.Mean age was 81.7 (SD:6.2) years, and 1147 (60.2%) patients were female. Mean Logistic EuroSCORE was 21.1% (SD:13.7). Transfemoral, transapical, transaortic and transaxillary TAVI was performed in 1252 (65.8%), 630 (33.1%), 18 (0.9%) and 4 (0.2%) patients, respectively. Operative mortality was 7.2% (137 patients). The VARC-2 outcomes were as follows: device success, 88.1%; disabling stroke, 1.0%; life-threatening and major bleeding 9.8 and 10.5%, respectively; major vascular complication, 9.7%; acute kidney injury, 8.2%; acute myocardial infarction 72 h, 1.5%. Perioperative pacemaker implantation was necessary in 116 (6.1%) patients. At discharge, the mean transprosthetic gradient was 10.7 (SD:4.5) mmHg. Incidence of postoperative mild, moderate or severe paravalvular leak was, respectively, 32.1, 5.0 and 0.4%. A total of 444/1767 (25.1%) deaths after hospital discharge were reported: of these, 168 (37.8%) were classified as cardiac death. Preoperative independent predictors of all-cause mortality were male gender (HR: 1.395; 95% CI:1.052-1.849); overweight, BMI 25-30 kg/mTAVI with a balloon-expandable device in the real world shows good mid-term outcomes in terms of survival, technical success, valve-related adverse events and haemodynamic performance.

No biomarker is available to predict prognosis of patients with advanced ovarian cancer (AOC) and guide the choice of chemotherapy. We performed a prospective-retrospective biomarker study within the MITO2 trial on the treatment of AOC.MITO2 is a randomised multicentre phase 3 trial conducted with 820 AOC patients assigned carboplatin/paclitaxel (carboplatin: AUC5, paclitaxel: 175 mg/m, every 3 weeks for 6 cycles) or carboplatin/PLD-pegylated liposomal doxorubicin (carboplatin: AUC5, PLD: 30 mg/m, every 3 weeks for 6 cycles) as first line treatment. Sixteen biomarkers (pathways of adhesion/invasion, apoptosis, transcription regulation, metabolism, and DNA repair) were studied in 229 patients, in a tissue microarray. Progression-free and overall survival were analysed with multivariable Cox model.After 72 months median follow-up, 594 progressions and 426 deaths were reported; there was no significant difference between the two arms in the whole trial. No biomarker had significant prognostic value. Statistically significant interactions with treatment were found for DNA-dependent protein kinase (DNA-PK) and phosphorylated acetyl-coenzymeA carboxylase (pACC), both predicting worse outcome for patients receiving carboplatin/paclitaxel.These data show that in presence of DNA-PK or pACC overexpression, carboplatin/paclitaxel might be less effective than carboplatin/PLD as first line treatment of ovarian cancer patients. Further validation of these findings is warranted.

Objective: The goal of this article is to report the preliminary results of infrapopliteal percutaneous transluminal angioplasty stenting with the Nile Croco coronary bifurcated stent (Minvasys, Gennevilliers, France) for selected patients with critical limb ischemia (CLI). Methods: From October 2006 to December 2010, 31 patients with CLI with below-the-knee TransAtlantic Inter-Society Consensus C and D lesions at the popliteal (n = 17, 54.8%) and distal tibioperoneal trunk (n = 14, 45.2%) bifurcations, with suboptimal primary percutaneous transluminal angioplasty results (residual stenosis >30%, elastic recoiling, or dissection), with at least two-vessel runoff to the foot (present or after percutaneous transluminal angioplasty), free of aortoiliac arterial disease, and at high surgical risk (more than three risk factors) were treated with the Nile Croco coronary bifurcated stent. Study end points included technical success, immediate and midterm primary and secondary patency rates, clinical improvement, and limb salvage. Results: Technical success was achieved in all patients (100%) without any intraoperative complications. Early complications included an acute stent occlusion and an acute compartment syndrome for a collateral arterial branch perforation. Median follow-up was 12.1 months (range, 1-32). Primary and secondary patency rates were 96.7% and 86.2% (95% confidence interval [CI], 67.2%-94.6%) at 30 days and and 100% and 96.6% (95% CI, 78.0%-99.5%) at 1 year, respectively. Clinical improvement (an upward shift of at least two Rutherford categories) was achieved in 28 patients (90.3%). A major amputation was required in one patient (3.2%). The overall limb salvage rate at 1 year was 96.7% (95% CI, 78.6%-99.5%). Conclusions: Preliminary data suggest that the Nile Croco bifurcated stent for below-the-knee angioplasty in selected patients with CLI is associated with high rates of technical success, early and midterm patency, and clinical improvement. Limb salvage rates are acceptable for this technically highly challenging anatomy, yet further studies with larger patient populations are necessary to validate these results.

Background and aim: Recurrence of diverticulitis is frequent within 5 years from the uncomplicated first attack, and its prophylaxis is still unclear. We have undertaken a multicentre, randomised, double-blind, placebo-controlled pilot study in order to evaluate the role of mesalazine in preventing diverticulitis recurrence as well as its effects on symptoms associated to diverticular disease. Methods: Ninety-six patients with the recent first episode of uncomplicated diverticulitis were randomised to receive mesalazine 800 mg twice daily for 10 days every month or placebo for 24 months. The primary efficacy end point was the diverticulitis recurrence at intention to treat analysis. Clinical evaluations were performed using the Therapy Impact Questionnaire (TIQ) for physical condition and quality of life at admission and at 3-month intervals. Treatment tolerability and routine biochemistry parameters as well as the use of additional drugs were also evaluated. Results: Ninety-two patients (mean age, 61.5) completed the study, 45 of whom received mesalazine, and 47, placebo. Diverticulitis relapse incidence in mesalazine-treated group was 5/45 (11 %) at the 12th month and 6/45 (13 %) at the 24th month; in the placebo-treated group, the correspondent rates were 13 % (6/47) and 28 % (13/47), respectively. Mean values of TIQ at 24 months were significantly better in mesalazine-treated group than in placebo-treated group (p = 0.02); in addition, average additional drug consumption was significantly lower (-20.4 %, p < 0.03) in mesalazine than in placebo. Conclusions: Diverticulitis recurrence occurred in as many as 28 % of patients under placebo within 24 months from the initial episode. Intermittent prophylaxis with mesalazine did not significantly reduce the risk of relapse but induced a significant improvement of patients' physical conditions and significantly lowered the additional consumption of other gastrointestinal drugs. © 2013 Springer-Verlag Berlin Heidelberg.

Expert Review of Anticancer Therapy | Year: 2012

Sequencing decisions in advanced renal cell carcinoma are likely to become more difficult when new targeted agents are approved for first and subsequent lines of therapy. Approximately 70% of patients benefit from targeted therapy before progression, of which 20% can be described as short-term responders (progression-free survival: <6 months) and 50% as long-term responders (progression-free survival: >6 months). The remaining 30% show either no response (20%) or are intolerant to treatment (10%). The challenge is to establish the optimal second-line agent for over 70% of patients who progress following initial response to a first-line tyrosine kinase inhibitor. As it is impossible to define the optimal second-line therapy for every patient, it is suggested that age and comorbidities of the patient, the sites of disease and the side effects of previous therapies be taken into account in order to optimize the use of different agents sequentially. © 2012 2012 Expert Reviews Ltd.

Previous attempts to replace ethinylestradiol (EE) with 17β-estradiol (E2) in combined oral contraceptives (COCs) have proved unsatisfactory in terms of bleeding outcomes. A review of previous studies of E2-based COCs has shown that, despite good ovulation inhibition, bleeding irregularities affected up to 100% of women, often resulting in high rates of discontinuation (up to 42%). Suggested reasons for the bleeding irregularities observed with these predominantly monophasic estradiol-progestin preparations included suboptimal doses of E2 and an inappropriate estrogen/progestin ratio. The progestin used in the investigated formulations (e.g., norethisterone acetate, desogestrel and cyproterone acetate) may also have affected the overall bleeding profile. More recent studies of a multiphasic COC containing estradiol valerate (E2V) and dienogest (DNG) indicate efficient ovulation inhibition and acceptable cycle control. In a randomized, double-blind trial that compared E2V/DNG with a monophasic COC comprising EE/levonorgestrel (LNG), the occurrence of scheduled withdrawal bleeding per cycle with E2V/DNG and EE/LNG was 77.7-83.2% and 89.5-93.8%, respectively. The intensity and duration of withdrawal bleeding was reduced with E2V/DNG. The incidence of intracyclic bleeding was similar with E2V/DNG (10.5-18.6%) and EE/LNG (9.9-17.1%). This review shows that after several unsatisfactory attempts to develop E2-based COCs, more recent studies employing endometrial-focused progestins, e.g., DNG, and multiphasic dosing regimens appear to be a promising approach for an E2-based COC that provides efficient ovulation inhibition and acceptable cycle control. © 2010 Elsevier Inc.

Bilateral salpingo-oophorectomy (BSO) in carriers of BRCA1 and BRCA2 mutations is widely recommended as part of a risk-reduction strategy for ovarian or breast cancer due to an underlying genetic predisposition. BSO is also performed as a therapeutic intervention for patients with hormone-positive premenopausal breast cancer. BSO may be performed via a minimally invasive approach with the use of three to four 5 mm and/or 12 mm ports inserted through a skin incision. To further reduce the morbidity associated with the placement of multiple port sites and to improve cosmetic outcomes, single-port laparoscopy has been developed with a single access point from the umbilicus. The purpose of this study was to evaluate the surgical outcomes associated with reducing the risks of salpingo-oophorectomy performed in a single port, while comparing multiport laparoscopy in women with a high risk for ovarian cancer. Single-port laparoscopy–BSO is feasible and safe, with favorable surgical and cosmetic outcomes when compared to conventional laparoscopy. © 2015, Angioni et al.
