RESUMEN

Purpose: In modern breast cancer treatment, a growing role has been observed for breast reconstruction together with an increase in clinical indications for postmastectomy radiotherapy (PMRT). Choosing the optimum type of reconstructive technique is a clinical challenge. We therefore conducted a national multicenter study to analyze the impact of PMRT on breast reconstruction. Methods: We conducted a retrospective case-control multicenter study on women undergoing breast reconstruction. Data were collected from 18 Italian Breast Centres and stored in a cumulative database which included the following: autologous reconstruction, direct-to-implant (DTI), and tissue expander/immediate (TE/I). For all patients, we described complications and surgical endpoints to complications such as reconstruction failure, explant, change in type of reconstruction, and reintervention. Results: From 2001 to April 2020, 3116 patients were evaluated. The risk for any complication was significantly increased in patients receiving PMRT (aOR, 1.73; 95% CI, 1.33-2.24; p < 0.001). PMRT was associated with a significant increase in the risk of capsular contracture in the DTI and TE/I groups (aOR, 2.24; 95% CI, 1.57-3.20; p < 0.001). Comparing type of procedures, the risk of failure (aOR, 1.82; 95% CI, 1.06-3.12, p=0.030), explant (aOR, 3.34; 95% CI, 3.85-7.83, p < 0.001), and severe complications (aOR, 2.54; 95% CI, 1.88-3.43, p < 0.001) were significantly higher in the group undergoing DTI reconstruction as compared to TE/I reconstruction. Conclusion: Our study confirms that autologous reconstruction is the procedure least impacted by PMRT, while DTI appears to be the most impacted by PMRT, when compared with TE/I which shows a lower rate of explant and reconstruction failure. The trial is registered with NCT04783818, and the date of registration is 1 March, 2021, retrospectively registered.

RESUMEN

BACKGROUND: Autologous fat grafting (AFG), defined as the re-implant to the breast of fat tissue from different body areas, has been firstly applied to esthetic plastic surgery and then has moved to reconstructive surgery, mainly used for scar correction and opposite breast altering. Nevertheless, due to the potentially unsafe stem-like properties of adipocytes at the tumoral bed level, no clear evidence of the procedure's oncological safety has been clearly documented at present. PATIENTS AND METHODS: We retrospectively collected data of early breast cancer (BC) patients from 17 Italian Breast Units and assessed differences in terms of locoregional recurrence rate (LRR) and locoregional recurrence-free survival (LRFS) between patients who underwent AFG and patients who did not. Differences were analyzed in the entire cohort of invasive tumors and in different subgroups, according to prognostic biological subtypes. RESULTS: With a median follow-up time of 60 months, LRR was 5.3% (n = 71) in the matched population, 3.9% (n = 18) in the AFG group, and 6.1% (n = 53) in the non-AFG group, suggesting non-inferiority of AFG (p = 0.084). Building Kaplan-Meier curves confirmed non-inferiority of the AFG procedure for LRFS (aHR 0.73, 95% CI 0.41-1.30, p = 0.291). The same effect, in terms of LRFS, was also documented among different biological subtypes (luminal-like group, aHR 0.76, 95% CI 0.34-1.68, p = 0.493; HER2 enriched-like, aHR 0.89, 95% CI 0.19-4.22, p = 0.882; and TNBC, aHR 0.61, 95% CI 0.12-2.98, p = 0.543). CONCLUSIONS: Our study confirms in a very large, multicenter cohort of early BC patients that, aside the well-known benefits on the esthetic result, AFG do not interfere negatively with cancer prognosis.

RESUMEN

Colorectal cancer incidence in patients undergoing screening protocols is decreasing because of the higher rate of discovered preneoplastic colonic lesions; however, adenomatous polyps may not always be removable endoscopically and surgery may still be necessary. The aim of this study was to assess the vascular endothelial growth factor expression in the different steps of colorectal carcinogenesis to explore its potential role as a marker of malignancy in polypoid lesions. A total of 92 subjects with colonic adenoma or cancer who underwent screening colonoscopy or surgery were prospectively enrolled. Real-time reverse transcription polymerase chain reaction for VEGF-A messenger RNA expression and immunohistochemistry for VEGF-A were performed. Immunoassays for VEGF-A, VEGF-C, VEGFR-1, VEGFR-2, and VEGFR-3 were also performed. Non-parametric statistics, receiver operating characteristic curve analysis, and logistic multiple regression analysis were used. VEGF-A messenger RNA expression was higher in patients with high-grade dysplasia or colorectal cancer than in those with low-grade dysplasia adenomas (p = 0.01). At immunohistochemistry, VEGF-A expression was significantly higher in colorectal cancer patients compared to dysplastic adenomas (p < 0.001), and the accuracy of VEGF-A expression for prediction of malignancy was 91.7 (95% confidence interval = 78.7-97.9). VEGF-C protein expression was lower in colorectal cancer patients than in simple adenomas (p = 0.02). VEGF-A levels were directly correlated to polyp size (rho = 0.73, p = 0.0062). Multivariate analysis demonstrated that malignancy and polyp size were independent predictors of VEGF-A mucosal levels. This study demonstrated that the VEGF-A expression changes along the colorectal carcinogenesis pathway showing a neat step up at the passage from high-grade dysplasia to invasive cancer. This feature might potentially be useful to stratify colorectal polyps in different risks of progression classes. Moreover, the high level of VEGF-A expression predicted the presence of lymphovascular invasion with good accuracy.

RESUMEN

OBJECTIVES/HYPOTHESIS: Right nonrecurrent inferior laryngeal nerve (NRLN) is an anatomical variant reported with a variable prevalence (0.3%-6%). It is associated with some arterial abnormalities (absence of the brachiocephalic trunk and presence of a right aberrant subclavian lusorian artery) that may be identified by preoperative ultrasonography (pUS). NRLN represents a major morbidity risk factor during neck surgery. The aim of this study was to verify pUS accuracy in predicting NRLN and to assess the impact of this technique on NRLN detection rate and laryngeal morbidity. STUDY DESIGN: Retrospective. METHODS: The study included 1,477 patients undergoing thyroid and parathyroid surgery with right-side inferior laryngeal nerve exploration. pUS was performed in 878 patients (pUS group); no preoperative attempts were performed in the remaining 599 patients (controls). Demographics, disease type, intraoperative inferior laryngeal nerve anatomy, and laryngeal morbidity were compared. RESULTS: No differences occurred between the two groups concerning demographics and disease type. NRLN was detected in 17 patients (1.9%) of the pUS group and in four patients (0.6%) of controls (P < 0.05). pUS predicted NRLN in all cases, with an overall accuracy > 98%. Overall laryngeal nerves morbidity was 1.8% in the pUS group and 4.2% in the controls (P < 0.05). NRLN palsy never occurred in the pUS group, whereas it occurred three times in the controls (P < 0.005). CONCLUSION: NRLN is accurately predicted by pUS. It occurs more frequently than expected because it may be misdiagnosed when no preoperative suspicion is available. Preoperative NRLN detection by pUS prevents inferior laryngeal nerve injuries.

RESUMEN

BACKGROUND: Acupuncture is a safe and well-tolerated treatment for pain relief. Previous studies supported the effectiveness of several acupuncture techniques for postoperative pain. The aim of this randomized, controlled trial was to evaluate the efficacy of acupuncture in reducing pain after thyroid surgery. METHODS: We randomized 121 patients to a control group (undergoing only standard postoperative analgesic treatment with acetaminophen) and an acupuncture group, undergoing also either electroacupuncture (EA) or traditional acupuncture (TA). Pain was measured according to intraoperative remifentanil use, acetaminophen daily intake, Numeric Rating Scale (NRS), and McGill Pain Questionnaire on postoperative days (POD) 1-3. RESULTS: Acupuncture group required less acetaminophen than controls at POD 2 (P = .01) and 3 (P = .016). EA patients required less remifentanil (P = .032) and acetaminophen than controls at POD 2 (P = .004) and 3 (P = .008). EA patients showed a trend toward better NRS and McGill scores from POD 1 to 3 compared with controls. EA patients had a lower remifentanil requirement and better NRS and McGill scores than TA patients. No differences occurred between TA patients and controls. CONCLUSION: Acupuncture may be effective in reducing pain after thyroid surgery. EA is more useful; TA achieves no significant effects.

RESUMEN

McBurney's procedure represented the gold-standard for acute appendicitis until 1981, but nowadays the number of laparoscopic appendectomies has progressively increased since it has been demonstrated to be a safe procedure, with excellent cosmetic results and it also allows a shorter hospitalization, a quicker and less painful postoperative recovery. The aim of this editorial was to perform a review of the literature in order to address controversial issues in the treatment of acute appendicitis.
