12-month efficacy of a single radiofrequency ablation on autonomously functioning thyroid nodules.

PurposeRadiofrequency ablation has been advocated as an alternative to radioiodine and/or surgery for the treatment of autonomously functioning benign thyroid nodules. However, only a few studies have measured radiofrequency ablation efficacy on autonomously functioning benign thyroid nodules. The aim of this work was to evaluate the 12-month efficacy of a single session of radiofrequency ablation (performed with the moving shot technique) on solitary autonomously functioning benign thyroid nodules.MethodsThirty patients with a single, benign autonomously functioning benign thyroid nodules, who were either unwilling or ineligible to undergo surgery and radioiodine, were treated with radiofrequency ablation between April 2012 and May 2015. All the patients underwent a single radiofrequency ablation, performed with the 18-gauge needle and the moving shot technique. Clinical, laboratory, and ultrasound evaluations were scheduled at baseline, and after 1, 3, 6, and 12 months from the procedure.ResultsA single radiofrequency ablation reduced thyroid nodule volume by 51, 63, 69, and 75 % after 1, 3, 6, and 12 months, respectively. This was associated with a significant improvement of local cervical discomfort and cosmetic score. As for thyroid function, 33 % of the patients went into remission after 3 months, 43 % after 6 months, and 50 % after 12 months from the procedure. This study demonstrates that a single radiofrequency ablation allowed us to withdraw anti-thyroid medication in 50 % of the patients, who remained euthyroid afterwards.ConclusionThis study shows that a single radiofrequency ablation was effective in 50 % of patients with autonomously functioning benign thyroid nodules. Patients responded gradually to the treatment. It is possible that longer follow-up studies might show greater response rates.

Interval Breast Cancer Versus Screen-Detected Cancer: Comparison of Clinicopathologic Characteristics in a Single-Center Analysis

Background: The introduction of breast screening programs has raised the problem of interval breast cancers (IBC). The aims of this study were to analyze the impact of IBC on the screening program, to compare IBC and screen‐detected cancers (SDC), and to identify possible predictors of mortality. Patients and Methods: Patients with breast cancer diagnosed during the regional breast screening program between January 2008 and December 2013 at a single center in Italy were included. Demographic, preoperative, and postoperative data were prospectively collected and retrospectively analyzed. Results: Five hundred thirty‐four patients were enrolled; 106 women (19.9%) had IBC and 428 women (80.1%) SDC. IBC presented more aggressive features compared to SDC, such as tumor invasiveness (95% vs. 85%; P = .005), tumor size (≥ pT2 37% vs. 21%; P = .001), grade (G3 39% vs. 17%; P < .001), and St Gallen molecular subtype (triple negative 22% vs. 7%; P < .001), resulting in higher distant recurrence rate (8% vs. 2%; P = .009) and worse overall and disease‐free survival (P = .03 and P = .001, respectively). Cox multivariate regression analysis identified St Gallen molecular subtype as the only predictor of mortality in patients with breast cancer (P = .03). Conclusion: IBC accounted for one‐fifth of all breast cancers diagnosed in women who followed the regional screening program. Furthermore, IBC appeared to have more aggressive features compared to SDC, leading to worse survival. These worse survivals depended on St Gallen molecular subtype. Micro‐Abstract: Interval breast cancers (IBC) have been of great concern since breast mammogram screening programs were introduced. We compared IBC to screen‐detected cancers (SDC). IBC accounted for one‐fifth of all breast cancers diagnosed in women who followed the regional screening program. IBC appeared to be more aggressive than SDC in terms of tumor invasiveness, size, and St Gallen molecular subtype, leading to worse overall and disease‐free survival.

Modifiable and non-modifiable risk factors for surgical site infection after colorectal surgery: a single-center experience

PurposeSurgical site infection (SSI) is the most common complication of colorectal surgery, resulting in significant burden in terms of morbidity and length of hospital stay. The aims of this study were to establish the incidence of SSI in patients undergoing colorectal surgeries and to identify potentially modifiable risk factors to reduce overall SSI rates.MethodsThis retrospective study analyzed patients who underwent colorectal resection at our Department. Patients were identified using a prospective SSI database. Univariate and multivariate analyses were used to identify risk factors.ResultsA total of 687 patients were enrolled in the study and the overall SSI rate was 19.9% (137 patients). Superficial incisional surgical site infections (SSSIs) developed in 52 (7.6%) patients, deep incisional surgical site infections (DSSIs) developed in 15 (2.2%), and organ/space infections (OSIs) developed in 70 (10.1%). Univariate and multivariate analyses confirmed that age, diabetes, emergency surgery, and a high infection risk index are risk factors for SSI.ConclusionsThere are some modifiable and non-modifiable risk factors for SSI. IRI and age are non-modifiable, whereas the timing of surgery and diabetes can be modulated by trying to defer some emergency procedures to elective ones and normalizing the glycemia of diabetic patients.

3D Vision Provides Shorter Operative Time and More Accurate Intraoperative Surgical Performance in Laparoscopic Hiatal Hernia Repair Compared With 2D Vision.

Background. The aim of this study is to evaluate if 3-dimensional high-definition (3D) vision in laparoscopy can prompt advantages over conventional 2D high-definition vision in hiatal hernia (HH) repair. Study design. Between September 2012 and September 2015, we randomized 36 patients affected by symptomatic HH to undergo surgery; 17 patients underwent 2D laparoscopic HH repair, whereas 19 patients underwent the same operation in 3D vision. Results. No conversion to open surgery occurred. Overall operative time was significantly reduced in the 3D laparoscopic group compared with the 2D one (69.9 vs 90.1 minutes, P = .006). Operative time to perform laparoscopic crura closure did not differ significantly between the 2 groups. We observed a tendency to a faster crura closure in the 3D group in the subgroup of patients with mesh positioning (7.5 vs 8.9 minutes, P = .09). Nissen fundoplication was faster in the 3D group without mesh positioning (P = .07). Conclusions. 3D vision in laparoscopic HH repair helps surgeon’s visualization and seems to lead to operative time reduction. Advantages can result from the enhanced spatial perception of narrow spaces. Less operative time and more accurate surgery translate to benefit for patients and cost savings, compensating the high costs of the 3D technology. However, more data from larger series are needed to firmly assess the advantages of 3D over 2D vision in laparoscopic HH repair.

Breastfeeding: a reproductive factor able to reduce the risk of luminal B breast cancer in premenopausal White women

In the medical literature, the role of breastfeeding and reproductive factors in the risk of breast carcinoma is still an open debate in premenopausal women. We highlight the role of breastfeeding and reproductive factors in luminal A and luminal B, the most frequent breast cancers. This case–control study analyzes a White premenopausal population of 286 breast cancer patients, divided into molecular subtypes, and 578 controls matched by age. Multivariate logistic regression models were used to assess the relationships of breastfeeding and other reproductive factors (age at menarche, parity, age at first pregnancy, number of children) with the risk of breast cancers. Among the variables examined, reproductive factors did not alter the risk of cancer, whereas breastfeeding up to 12 months was a significant protective factor against luminal B breast cancer (multivariate odds ratio: 0.22, 95% confidence interval: 0.09–0.59, P=0.002). In contrast, luminal A cases did not significantly correlate with breastfeeding or other reproductive factors. Breastfeeding up to 12 months is strongly protective against the more aggressive luminal B, but not against the less aggressive luminal A breast cancer in premenopausal White women.

Ileocecal valve syndrome after surgery in adult patients: Myth or reality?

The onset of symptoms after removal of the ileocaecal valve (ICV) may be perceived as an unwanted effect of surgery and induce patients to bring unnecessary litigation against surgeons. The aim of our study is to assess the real impact on the quality of life of patients whose ICV has been surgically removed, using three validated questionnaires.

Patient satisfaction after thyroid RFA versus surgery for benign thyroid nodules: a telephone survey

Abstract Introduction: Minimally invasive nonsurgical techniques are gaining ground as alternatives to surgery for the treatment of benign thyroid nodules. Here, we aimed at comparing patient satisfaction after radiofrequency ablation (RFA) to that after surgery. Methods: In this cross-sectional study, we recruited 126 patients treated with RFA and 84 treated with surgery for a single benign thyroid nodule. All patients were contacted by phone call and were asked the following questions: Are you satisfied with the symptom resolution?; Are you satisfied with the cosmetic results?; Are you satisfied overall with the procedure?; Are you taking any medication for your thyroid? Patients’ general characteristics were collected from our database. Results: In the surgery group, there was a higher percentage of patients fully satisfied with the resolution of nodule-related symptoms (p = .02). In the RFA group, there was a higher percentage of patients fully satisfied with the cosmetic results (p = .001). In terms of overall satisfaction, there were no differences between the groups (p = .26). Nevertheless, RFA led to differing results based on thyroid nodule function. In patients with nonfunctioning thyroid nodules, RFA was as effective as surgery in terms of satisfaction with symptom resolution, while it was not in patients with autonomously functioning thyroid nodules (AFTN). Conclusion: Our data on postoperative patient satisfaction support the notion that both RFA and surgery are valid therapeutic options for nonfunctioning thyroid nodules, while surgery should be still preferred for AFTN.

Current Status of Fibroblast Growth Factor Receptor-Targeted Therapies in Breast Cancer

Breast cancer (BC) is the most common malignancy and second only to lung cancer in terms of mortality in women. Despite the incredible progress made in this field, metastatic breast cancer has a poor prognosis. In an era of personalized medicine, there is an urgent need for better knowledge of the biology leading to the disease, which can lead to the design of increasingly accurate drugs against patients’ specific molecular aberrations. Among one of the actionable targets is the fibroblast growth factor receptor (FGFR) pathway, triggered by specific ligands. The Fibroblast Growth Factor Receptors/Fibroblast Growth Factors (FGFRs/FGFs) axis offers interesting molecular targets to be pursued in clinical development. This mini-review will focus on the current knowledge of FGFR mutations, which lead to tumor formation and summarizes the state-of-the-art therapeutic strategies for targeted treatments against the FGFRs/FGFs axis in the context of BC.

Outcome of laparoscopic gastric bypass in obese and diabetic patients: when surgery fails.

BACKGROUND The beneficial effects of bariatric surgery on diabetes and obesity have been widely demonstrated in the literature. The aim of our study was to evaluate the rate of failure of laparoscopic gastric bypass both in terms of weight loss and metabolic remission after one follow-up year. METHODS A longitudinal, multicenter prospective study was carried out on 771 patients affected by pathological obesity. The following parameters were recorded for each patient before surgery: anthropometric, metabolic, social, smoking habits and previous failure of other bariatric procedures. After 1 follow-up year, final weight, final Body Mass Index (BMI), final percentage of lost excess body weight and percentage of lost BMI were evaluated. RESULTS Statistical analysis showed a correlation between BMI>50 kg/m2, presence of metabolic syndrome, presence of diabetes, gastric pouch volume greater than 60 mL and failure of weight loss outcome. Statistical analysis of metabolic failure has recognized a high preoperative glycated hemoglobin percentage (HbA1c%) value as a statistically significant negative predictive factor. CONCLUSIONS Bariatric Surgery is the most effective treatment for weight loss and metabolic improvement. However, in our study, surgery did not achieve the expected outcome in patients with specific metabolic, anthropometric and surgical characteristics (BMI>50 kg/m2, presence of metabolic syndrome, presence of T2DM with high preoperative HbA1c% level and gastric pouch volume greater than 60 mL).

ECOG or Karnofsky Performance Status to Assess Functionality in Glioblastoma Patients Among Different Observers

Purpose: Glioblastoma (GB) patients usually have symptoms that affect their functional status, and medical staff, as well as the patients and their caregivers, might have different perceptions about it. The performance status is important to establish a patient’s survival prediction and treatment decisions. This study was aimed to explore whether health care providers, patients, and caregivers have a common perception of patients’ functional statuses and to investigate in further studies whether the functional scales used in oncology clinical practice are objective tools to evaluate brain tumour patients. Methods: GB patients treated at our Neuro-Oncology Unit were evaluated once using Eastern Cooperative Oncology Group Performance Status (ECOG) and Karnofsky Performance Status (KPS) by a medical oncologist (MO), an independent investigator (II), the patient and the patient’s main caregiver. Results: Fifty patients were enrolled. Concordance in KPS evaluation among the four observers was low (Fleiss’ Kappa=0.354; p<0.001) and moderate in ECOG one (Fleiss’ K=0.424; p<0.001). Pairing the observers, the concordance between the MO and II was strong (KPS Cohen’s Kappa=0.731; p<0.001, ECOG Cohen’s Kappa=0.741; p=0.001), whereas it was poor between the patient and MO (KPS Cohen’s Kappa=0.250; p=0.007. ECOG Cohen’s Kappa=0.241; p=0.009) and between the caregiver and MO (KPS Cohen’s Kappa=0.350; p<0.001. ECOG Cohen’s Kappa=0.346; p=0.000). Conclusion: Concordance among the observers was poor or moderate according to the functional scale used. Particularly, caregivers’ perception of the patients’ functional status was frequently worse than that of the professionals.
