Surgery and adjuvant therapies in the treatmentof stage IV melanoma: our experience in 84 patients
No full textBackground and aims Survival rates of patients with stage IV melanoma are poor: Median survival is 7–8 months and 5-year survival rates about 5%. There is no agreement on the role of surgery at this stage. Most patients with metastatic melanoma are not able to undergo resection and usually are sent to systemic chemo- and immunotherapy. Patients and methods Eighty-four patients operated on for stage IV melanoma were evaluated. Of them, 61.9% were submitted to reiterative surgery with 168 operations and 182 surgical procedures overall. A total of 90.5% was submitted to adjuvant therapies according to aggressive and reiterated schedules: chemotherapy, immunotherapy, dendritic cells vaccine, infusion of tumor infiltrating lymphocytes, local therapies as electrochemotherapy. Results The mean overall survival (Kaplan–Meier) was 56.7 months (1 year: 72.1%, 3 years: 46.5%, 5 years: 23.16%). The survival of reiterative surgery was significatively longer than single surgery (62.7 vs 42.4 months
Conversion Surgery in Gastric Cancer Carcinomatosis
No full textBackground: After the REGATTA trial, patients with stage IV gastric cancer could only benefit from chemotherapy (CHT). However, some of these patients may respond extraordinarily to palliative chemotherapy, converting their disease to a radically operable stage. We present a single centre experience in treating peritoneal carcinomatosis from gastric cancer. Methods: All patients with stage IV gastric cancer with peritoneal metastases as a single metastatic site operated at a single centre between 2005 and 2020 were included. Cases were grouped according to the treatment received. Results: A total of 118 patients were considered, 46 were submitted to palliative gastrectomy (11 were considered M1 because of an unsuspected positive peritoneal cytology), and 20 were submitted to Hyperthermic Intraperitoneal Chemotherapy (HIPEC) because of a <6 Peritoneal Cancer Index (PCI). The median overall survival (OS) after surgery plus HIPEC was 46.7 (95% CI 15.8–64.0). Surgery (without HIPEC) after CHT presented a median OS 14.4 (8.2–26.8) and after upfront surgery 14.7 (10.9–21.1). Patients treated with upfront surgery and considered M1 only because of a positive cytology, had a median OS of 29.2 (25.2–29.2). The OS of patients treated with surgery plus HIPEC were 60.4 months (9.2–60.4) in completely regressed cancer after chemotherapy and 31.2 (15.8–64.0) in those partially regressed (p = 0.742). Conclusions: Conversion surgery for peritoneal carcinomatosis from gastric cancer was associated with long survival and it should always be taken into consideration in this group of patients

Cytoreduction Plus Hyperthermic Intraperitoneal Chemotherapy in Primary and Recurrent Ovarian Cancer: A Single-Center Cohort Study
No full textEpithelial ovarian cancer (EOC) is the most frequent cause of death among women with gynecologic malignant tumors. Primary debulking surgery (PDS) with maximal surgical effort to reach completeness of cytoreduction, followed by chemotherapy, has become the standard of care; moreover, some experiences have shown that a comprehensive treatment approach of surgery combined with hyperthermic intraperitoneal chemotherapy (HIPEC) could improve the prognosis of ovarian cancer. We carried out a retrospective analysis of all consecutive sixty-six patients diagnosed with primary advanced or recurrent ovarian cancer who underwent debulking surgery plus HIPEC in a single center between September 2005 and October 2020. For 33 patients with primary EOC, with a median follow-up period of 70 months, the median overall survival was 56 months (range: 48.1–96.9); and the median disease-free survival (DFS) was 13 months (range: 19.9–53.7). In the recurrent population, the median follow-up period was 78 months, the median overall survival (OS) was 82 months (range: 48.1–96.9), and the median DFS was 17 months (range: 19.7–53.0). In our study, we have found that CRS plus HIPEC is feasible, with very low rates of major complications and good results in terms of overall survival

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods

Forecasting outcomes after cholecystectomy in octogenarian patients
No full textBackground: Although gallstone disease increases with aging, elderly patients are less likely to undergo cholecystectomy. This is because age itself is a negative predictor after cholecystectomy. The ACS-NSQIP risk calculator can therefore help surgeons decide whether to operate or not. However, little is known about the accuracy of this model outside the ACS National Surgical Quality Improvement Program. The aim of the present study is to evaluate the ability of the ACS-NSQIP model to predict the clinical outcomes of patients aged 80 years or older undergoing elective or emergency cholecystectomy. Study design: The study focused on 263 patients over 80 years of age operated on between 2010 and 2019: 174 were treated as emergencies because of acute cholecystitis (66.2%). Outcomes evaluated are those predicted by the ACS-NSQIP calculator within 30 days of surgery. The ACS-NSQIP model was tested for both discrimination and calibration. Differences among observed and expected outcomes were evaluated. Results: When considering all patients, the discrimination of mortality was very high, as it was that of severe complications. Considering only the elective cholecystectomies, the discrimination capacity of ACS-NSQIP risk calculator has consistently worsened in each outcome while it remains high considering the emergency cholecystectomies. In the evaluation of the emergency cholecystectomy, the model showed a very high discriminatory ability and, more importantly, it showed an excellent calibration. Comparisons between main outcomes showed small or even negligible differences between observed and expected values. Conclusion: The results of the present study suggest that clinical decisions on cholecystectomy in a patient aged 80 years or older should be assisted through the ACS-NSQIP model
