Safety and efficacy of percutaneous arterial port Implantation for Hepatic Arterial Infusion Chemotherapy.

OBJECTIVES: Approximately 40% of patients with colorectal cancer will develop liver metastases. Hepatic arterial infusion chemotherapy (HAIC) represents a valuable treatment option, with curative, palliative, or adjuvant intent. The aim of our study was to describe technical considerations, safety, and oncological outcomes of patients receiving HAIC. MATERIALS AND METHODS: All patients who underwent percutaneous hepatic arterial port placement in our institution between 2004 and 2021 were included in this retrospective analysis. Demographic, anatomical and technical data were collected. Tumor response was assessed using RECIST 1.1. Kaplan-Meier estimates were used for overall survival (OS) and hepatic progression-free survival (PFS). Adverse events (AEs) were graded using the Clavien-Dindo classification. RESULTS: A total of 360 patients (median age, 58.6 years [interquartile range (IQR): 49.5-65.4]; 208 men [57.8%]) were included. Percutaneous hepatic arterial port placement was successful in 87.9% of cases, resulting in 379 port placements (431 attempts). Overall, 394 HAIC courses were delivered, mostly oxaliplatin-based (94.7%), with a median of 6 cycles per course (IQR: 3-8). AEs (all grades) were observed in 42.0% of ports (grade IIIb-V: 1.1%). Most port dysfunctions could be resolved, resulting in a 73.1% rate of HAIC resumption, without impact on OS. Median OS was 22 months (IQR: 18-24), and median hepatic PFS was 11 months (IQR: 9.5-13). Tumor downstaging allowed surgery in 35.6% of patients, with significantly longer median OS than non-operated patients (39 months [IQR: 33-79] versus 14 months [IQR: 12-16], p < 0.001). CONCLUSION: This retrospective cohort study demonstrates the feasibility, safety, and efficacy of percutaneous hepatic arterial port placement with an impact on survival for selected patients. CLINICAL RELEVANCE STATEMENT: Percutaneous hepatic arterial port placement is feasible, safe and effective with an impact on the survival of selected patients. KEY POINTS: Hepatic arterial infusion chemotherapy provides promising tumor response and overall survival, especially in cases of resection/ablation. Total complication rate of hepatic arterial infusion chemotherapy port use is high, but serious complications are rare. Port revision is often necessary but allows the resumption of hepatic arterial infusion chemotherapy without affecting overall survival.

Vena cava leiomyosarcoma surgery results in a retrospective cohort of 41 patients from two centers.

BACKGROUND: Leiomyosarcoma of the vena cava (LMS-VC) is a rare entity with poor oncological outcomes and a lack of histological staging prognostic factors. METHODS: Outcomes of consecutive patients operated on LMS-VC between March 2003 and May 2022, in two specialized sarcoma centers were reported. RESULT: Forty-one patients were identified. Median size of LMS-VC was 9 cm with 68% of complete obstruction. After surgery, severe complication rate was 30%. No postoperative mortality was reported. Microscopic complete excision was obtained for 71% of patients, R1 for 27% and one patient presented an R2 resection. Grade 3 was found in 24%. After a median follow-up of 70 months, 3 years disease-free survival (DFS) and 5 years DFS were 34% and 17%, and 3 years overall survival (OS) and 5 years OS were 74% and 50%. Distant metastasis concerned 54% of recurrences, local 7% and local and distant 5%. Multivariate analysis showed that FNCLCC grade (p < 0.001) and perioperative chemotherapy (p = 0.026) were significant factors for DFS. In multivariate analysis, FNCLCC grade was a significant factor for OS (p = 0.004). DISCUSSION: Perioperative chemotherapy may have a role to play in lowering the risk of recurrence for LMS-VC, particularly in high-grade tumor.

Correlation between peritoneal cancer index and survival in advanced epithelial ovarian cancer with complete resection.

OBJECTIVE: The aim of this study was to investigate the relation between the peritoneal cancer index, overall survival, and recurrence free survival, in patients with epithelial ovarian cancer. METHODS: Patients treated at the Gustave-Roussy Institute between December 2004 and November 2017 for advanced epithelial ovarian cancer in complete resection were included. The correlation between the peritoneal cancer index and survival was studied using statistical modeling. Multivariate analysis was performed with a logistic regression model. RESULTS: Of the 351 patients included, 94 (27%) had initial surgery and 257 (73%) had interval surgery. Median follow-up was 52.7 months (range 47.6-63.9). Median peritoneal cancer index was 10 (range 0-32). The linear model best represented the relationship between peritoneal cancer index and overall survival. Patients with neoadjuvant chemotherapy had a greater instantaneous risk of baseline death than those with initial surgery, as well as a more rapid increase in this risk as the peritoneal cancer index increased. Overall survival and recurrence free survival were better in the initial surgery group (103.4 months (79.1-not reached (NR)) vs 66.5 months (59.1-95.3) and 31.8 months (23.7-48.7) vs 25.9 months (23.2-29), respectively). Risk factors for death were body mass index, peritoneal cancer index, and need for neoadjuvant chemotherapy. CONCLUSION: The peritoneal cancer index is a prognostic indicator, but its linear relationship with survival precluded setting a unique peritoneal cancer index cut-off. Moreover, the prognostic impact of peritoneal cancer index was stronger in the setting of neoadjuvant chemotherapy.

A novel fusion variant LSM14A::NR4A3 in extraskeletal myxoid chondrosarcoma.

Extraskeletal myxoid chondrosarcoma (EMC) is a rare soft tissue neoplasm of uncertain lineage characterized by the pathognomonic rearrangement of the NR4A3 gene, which in most cases is fused with EWSR1. Other NR4A3 fusion partners have been described, namely TAF15, FUS, TCF12, and TGF. Some studies suggest that EMCs with non-EWSR1 variant fusion are associated with high-grade morphology and worst clinical behavior compared to EWSR1::NR4A3 tumors, supporting the potential significance of particular fusion variant in EMC. We report a case of a 34-year-old male who presented with calf EMC and subsequently developed a slowly progressive metastatic disease 3 years after diagnosis. Whole-transcriptome analysis with total RNA sequencing enabled identification of a novel fusion transcript LSM14A::NR4A3, expanding the molecular spectrum of EMC.

Initial laparoscopic liver resection is associated with reduced adhesions and transfusions at the time of salvage liver transplantation.

BACKGROUND: Laparoscopic liver resection (LLR) has been associated with improved patient recovery as well as reduced postoperative adhesions compared to open LR (OLR) and could therefore facilitate redo liver surgery. LLR prior to liver transplantation (LT) is increasingly performed, LT being saved for HCC recurrence. LT is still performed by open surgery due to vascular reconstructions and underlying liver chronic disease. We evaluated the impact of laparoscopic approach for LR prior to LT in terms of intraoperative transfusions, adhesions severity and outcome. METHODS: Data from all patients who underwent a LT after LR in two French high-volume tertiary centers were retrospectively reviewed. The impact of LLR on per operative and postoperative outcome was assessed using logistic regression. RESULTS: 170 patients were included, 43 patients in the LLR group and 127 in the OLR group. Preoperative characteristics were comparable between both groups, except LLR group included more patients with "very early-stage" BCLC tumors than OLR group (51% vs. 33%, p = 0.02) and less anatomical resections (54% vs. 75%, p = 0.015). During LT, the transfusion rate was significantly higher in the OLR group (71.4% vs 44.2%, p = 0.002) as well as the proportion of type III adhesions according to OLSG classification (p < 0.001). Multivariate analysis found LLR to be an independent protective factor for adhesions and transfusion (p = 0.001 and p = 0.03 respectively). CONCLUSION: Laparoscopic liver resection was associated with reduced postoperative adhesions and transfusion requirements during subsequent liver transplantation.

The Need for Centralization for Small Intestinal Neuroendocrine Tumor Surgery: A Cohort Study from the GTE-Endocan-RENATEN Network, the CentralChirSINET Study.

BACKGROUND: The concept of surgical centralization is becoming more and more accepted for specific surgical procedures. OBJECTIVE: The aim of this study was to evaluate the relationship between procedure volume and the outcomes of surgical small intestine (SI) neuroendocrine tumor (NET) resections. METHODS: We conducted a retrospective national study that included patients who underwent SI-NET resection between 2019 and 2021. A high-volume center (hvC) was defined as a center that performed more than five SI-NET resections per year. The quality of the surgical resections was evaluated between hvCs and low-volume centers (lvCs) by comparing the number of resected lymph nodes (LNs) as the primary endpoint. RESULTS: A total of 157 patients underwent surgery in 33 centers: 90 patients in four hvCs and 67 patients in 29 lvCs. Laparotomy was more often performed in hvCs (85.6% vs. 59.7%; p < 0.001), as was right hemicolectomy (64.4% vs. 38.8%; p < 0.001), whereas limited ileocolic resection was performed in 18% of patients in lvCs versus none in hvCs. A bi-digital palpation of the entire SI length (95.6% vs. 34.3%, p < 0.001), a cholecystectomy (93.3% vs. 14.9%; p < 0.001), and a mesenteric mass resection (70% vs. 35.8%; p < 0.001) were more often performed in hvCs. The proportion of patients with ≥8 LNs resected was significantly higher (96.3% vs. 65.1%; p < 0.001) in hvCs compared with lvCs, as was the proportion of patients with ≥12 LNs resected (87.8% vs. 52.4%). Furthermore, the number of patients with multiple SI-NETs was higher in the hvC group compared with the lvC group (43.3% vs. 25.4%), as were the number of tumors in those patients (median of 7 vs. 2; p < 0.001). CONCLUSIONS: Optimal SI-NET resection was significantly more often performed in hvCs. Centralization of surgical care of SI-NETs is recommended.

Systemic Therapy in Advanced Pleomorphic Liposarcoma: a Comprehensive Review.

OPINION STATEMENT: The therapeutic approach of pleomorphic liposarcoma (PLPS), a rare high-grade subgroup of soft tissue sarcoma, is commonly extrapolated from the management of other LPS subtypes. Only published retrospective data on PLPS currently serve as a guide for oncologists without clear recommendations or specific guidelines. In the advanced setting, specific systemic therapy such as eribulin and trabectedin showed promising activity in comparison to conventional therapy (doxorubicin- and gemcitabine-based protocols), which currently remains the current standard of care at initial stages of the disease. The better understanding of soft tissue sarcoma (STS) pathophysiology and disease course has led to the development of adapted clinical trial designs for rare STS histotypes with specific treatment approach.

Life expectancy and likelihood of surgery in multiple endocrine neoplasia type 1: AFCE and GTE cohort study.

BACKGROUND: The overall natural history, risk of death and surgical burden of patients with multiple endocrine neoplasia type 1 (MEN1) is not well known. METHODS: Patients with MEN1 from a nationwide cohort were included. The survival of patients with MEN1 was compared with that of the general population using simulated controls. The cumulative probabilities of MEN1-specific operations and postoperative mortality were assessed, and surgical sequences were analysed using sunburst charts and Venn diagrams. RESULTS: A total of 1386 patients with MEN1 were included. Life expectancy was significantly reduced in patients with MEN1 compared with simulated controls from the general population, with a lifetime difference of 15 years. Mutations affecting the JunD interaction domain had a significant negative impact on survival. Survival for patients with MEN1 compared with the general population improved over time. The probability of experiencing at least one specific MEN1 operation was above 95 per cent after 75 years, and most patients had surgery at least twice during their lifetime. Time to a 50 per cent risk of MEN1 surgery was 30.5 years for patients born after 1960, compared with 47.9 years for those born before 1960. Sex and mutations affecting the JunD interacting domain had no impact on time to first surgery. There was considerable heterogeneity in surgical sequences, with no specific clinical pathway. CONCLUSION: Life expectancy was significantly lower among patients with MEN1 compared with the general population, and further decreased in patients with mutations affecting the JunD interacting domain. Almost all patients underwent at least one MEN1-specific operation during their lifetime, but there was no standardized sequence of surgery.

Acute Abdominal Complications in Deeply Neutropenic Onco-Hematology Patients: A Retrospective Series of 105 Cases.

BACKGROUND: Acute abdominal complications (AAC) in patients with deep neutropenia (DN) is challenging to manage because of the expected influence of AAC on oncological prognosis and higher surgical complication rate in a period of DN. In practice, these parameters are difficult to appreciate. This study reported our experience in managing these patients. METHODS: All consecutive patients treated in our tertiary care cancer center between 2010 and 2020 who developed AAC in the context of a DN were retrospectively analyzed. AAC was defined as an infection (intra-abdominal, perineal, or cutaneous), bowel obstruction, or intra-abdominal hemorrhage. FINDINGS: Among 105 patients, 18 (17%) required emergent surgery (group 1), 34 patients had a complication requiring surgical oversight (group 2), and 53 patients had a non-surgical etiology (group 3). Fifteen patients underwent surgery in the group 1, three in group 2, and one in group 3. Overall, 28 patients died during hospitalization. Mortality was statistically different between the groups (p = 0·01), with a higher rate in group 1 (n = 9/18, 50%) than in group 2 (n = 11/34, 32%) and group 3 (n = 8/53, 15%). All groups together had a median overall survival (OS) of 14 months and disease-free survival (DFS) of 10 months. OS was not comparable between the groups, and the median length of survival in group 1 was 6 months versus 8 months in group 2 and 23 months in group 3. In group 1, five patients (5/18, 28%) did not relapse at the end of the follow-up compared to 13 in group 2 (13/34, 38%) and 25 in group 3 (25/53, 47%). After discharge, OS and DFS were similar between the groups. INTERPRETATION: The advent of an AAC necessitating surgery in the context of DN is a deadly event associated with a 50% mortality; nonetheless, in case of unpostponable emergencies, surgery can provide long-term survival in selected patients.

Quality of Life After Caustic Ingestion.

OBJECTIVE: The aim of the study was to evaluate long-term QOL after caustic ingestion. BACKGROUND: Caustic ingestion strongly affects patient's QOL but data on the topic is scarce in the literature. METHODS: QOL evaluation was conducted in survivors from a large cohort of patients with caustic injuries. QOL was assessed using the EORTC QLQ-OG25 module, the SF12v2 score, and the hospital anxiety and depression scale questionnaire. One hundred thirty-four patients (59 men, median age 43) completed the survey; 72 (54%) patients underwent emergency digestive resection and in 99 (74%) patients underwent esophageal reconstruction. Results of QOL questionnaires were compared to average values determined in healthy volunteers and in patients with esophageal cancers. RESULTS: The median QLQ-OG25 score was 44 (34, 62) and values were significantly lower when compared to a normal population (P < 0.0001). SF12v2 scores were significantly inferior to those expected in a normal population on both the physical component summary (PCS) (43.3 ±â€Š10.8; P < 0.0001) and the mental component summary (44 ±â€Š9.7; P < 0.0001) scales. Emergency esophageal resection was significantly associated with higher QLQ-OG25 scores (P < 0.0001), but not with mental component summary (P = 0.3), PCS (P = 0.76), HAD anxiety (P = 0.95), and HAD depression scores (P = 0.59); results were similar after extended emergency resection. When compared to esophagocoloplasty alone, pharyngeal reconstruction had a significant negative impact on QLQ-OG25 (P < 0.0001), PCS (P = 0.01), and HAD depression (P = 0.0008) scores. CONCLUSIONS: QOL is significantly impaired after caustic ingestion. QOL issues should not influence the emergency surgical strategy but deserve discussion before esophageal reconstruction for caustic injuries.

Results After Conservative Surgery of Stage II/III Serous Borderline Ovarian Tumors.

OBJECTIVE: The aim of this study was to assess the outcomes of a large series of patients treated conservatively for stage II or III serous borderline tumors of the ovary (SBOTs) with a long-term follow-up. METHODS: Patients with SBOTs and peritoneal implants, treated in or referred to our institution, were retrospectively reviewed. Outcomes of patients treated conservatively (preservation of the uterus and at least a part of one ovary) to promote subsequent fertility were specifically analyzed. RESULTS: Between 1971 and 2017, 212 patients were identified and followed-up. Among these patients, 65 underwent conservative treatment; eight patients had invasive implants. Among patients treated conservatively, 38 (58%) patients recurred. Twenty-eight recurrences were observed under the form of borderline tumor on the spared ovary and/or noninvasive implants, but eight patients had a recurrence under the form of invasive disease. Compared with radical surgery, the use of conservative treatment (p < 0.0001) was a prognostic factor on disease-free survival (DFS), but without an impact on overall survival (OS). Nevertheless, three deaths occurred. Twenty-four pregnancies (13 spontaneous) were observed in 20 patients (29 patients wanted to become pregnant). CONCLUSION: In this series collecting the largest number of patients undergoing conservative surgery for stage II/III SBOTs, spontaneous pregnancies can be achieved after conservative treatment of advanced-stage disease, but the recurrence rate is high and three deaths were observed. These patients were spared their fertility but with a high rate of recurrence. Uncertainties regarding the safety of conservative treatment should be exposed to these patients.

Post-Radiation Grade 3 Neuroendocrine Carcinoma: A New Entity?

BACKGROUND: Cancer survivors have a 14% increased risk of developing a malignancy compared with the general population. Second radiation-induced malignancies with different histologies have been described in different organs. Based on individual observations, we hypothesized that neuroendocrine carcinoma (NEC) could arise in irradiated organs. METHODS: In a retrospective analysis of Gustave Roussy database of NEC patients (small cell lung cancer excluded) diagnosed as a second cancer, we looked for the frequency of grade 3 NEC that arose in patients who had received previous radiation therapy for a first cancer. Radiation therapy for the first cancer, dose, location of radiation therapy, pathological characteristics, overall survival, and response to treatment of secondary NEC were analyzed. RESULTS: From January 1995 to December 2017, 847 cases of NEC were seen at Gustave Roussy. Among them, 95 (11.2%) patients had a history of previous malignancy of which 36 (4%) had been treated with radiation therapy. Out of these 36 patients, 12 (1.4% of all NEC patients) developed a NEC within the previous irradiated organ (median dose of 50 Gy, range 36-67.5). Most frequent first cancers were breast cancer (n = 4) and Hodgkin lymphoma (n = 3). NEC arose within a median time of 21.7 years (range 5.1-36.4) from radiation in the thorax (n = 5), digestive tract (n = 3), and other sites. Five large cell NEC, 3 small cell NEC, 1 mixed neuroendocrine neoplasm and 3 not otherwise specified NEC were diagnosed. Ten patients had stage IV disease at diagnosis; median overall survival was 37.8 months (95% CI [17.6 to NA]). Three patients (25%) achieved complete response with multimodal treatment. CONCLUSIONS: NEC can arise from previously irradiated organs and may have a better outcome in this setting. Other risk factors should be investigated to explain the high rate of previous cancer in this population of neuroendocrine neoplasm.

Long-Term Results after Surgical Resection of Peritoneal Metastasis from Neuroendocrine Tumors.

INTRODUCTION: Peritoneal metastases from neuroendocrine tumors are associated with a bad prognosis. The objective of our study was to evaluate whether surgical resection could lead to prolonged survival in selected patients. This survival was compared to that of patients operated for liver metastasis. METHODS: From our prospectively maintained database we included 88 patients who underwent the complete resection of peritoneal and/or liver metastasis between January 1995 and December 2016 in Gustave-Roussy. Three resection groups were compared: peritoneal metastasis alone, liver metastasis alone, and the combined resection of liver and peritoneal metastases. RESULTS: The median peritoneal cancer index was 10 in the peritoneal group and 11 in the peritoneal + liver group. The 5-year overall survival was 81% (60-100) in the peritoneal group compared to 78% (65.2-92.8) in the liver group, and 72% (58.7-89.7) in the peritoneal + liver group (p = 0.71). The 3-year disease-free survival reached 26.9% (16.1-45.1) in the liver group, 12.5% (2.3-68.2) in the peritoneal group, and 32.4% (19.9-52.6) in the combined liver + peritoneal group (p = 0.45). In the univariate analysis, the prognosis factors for a longer survival were: small bowel primary tumor origin, low preoperative chromogranin A level, and tumor grade ≤1. CONCLUSION: Despite a high recurrence rate, long-term overall survival can be achieved after the resection of peritoneal metastasis in selected patients. This survival is comparable to that of patients operated for liver metastasis only. Surgery should stand as a standard treatment for peritoneal metastases in patients with resectable disease.

Surgical management of soft tissue tumors of the abdominal wall: A retrospective study in a high-volume sarcoma center.

BACKGROUND: The aim of the study is to evaluate functional and oncological outcomes of patients undergoing abdominal wall soft tissue tumors (AWSTT) surgery. METHODS: All consecutive patients that underwent surgery for malignant and intermediate AWSTT from 1999 to 2019 were retrospectively analyzed. RESULTS: Ninety-two patients were identified, 20 (22%) operated on for a desmoid tumor and 72 (78%) for a soft tissue sarcoma (STS). Fifty-two patients (57%) had in toto resection of the abdominal wall (from the skin to the peritoneum) and 9 (10%) required simultaneous visceral resection. The closure was direct in 28 patients (30%) and requiring a mesh, a flap or a combination of the two in respectively 42, 16, and 6 patients (47%, 17%, 6%). The postoperative complications rate was 26%. Thirteen patients (14%) developed an incisional hernia after a median delay of 27 months. After a median follow-up of 40 months, out of the 72 patients operated on for STS, 7 (10%) developed local recurrence and 11 (15%) distant recurrence. The median recurrence-free and overall survivals were 61 and 116, months respectively. CONCLUSIONS: Management of AWSTT requires extensive surgery but allows good local control with an acceptable rate of incisional hernia.

Acute Pancreatitis as the Initial Presentation of Pancreatic Adenocarcinoma does not Impact Short- and Long-term Outcomes of Curative Intent Surgery: A Study of the French Surgical Association.

BACKGROUND: Acute pancreatitis (AP) can be one of the earliest clinical presentation of pancreatic ductal adenocarcinoma (PDAC). Information about the impact of AP on postoperative outcomes as well as its influences on PDAC survival is scarce. This study aimed to determine whether AP as initial clinical presentation of PDAC impact the short- and long-term outcomes of curative intent pancreatic resection. PATIENTS AND METHODS: From 2004 to 2009, 1449 patients with PDAC underwent pancreatic resection in 37 institutions (France, Belgium and Switzerland). We used univariate and multivariate analysis to identify factors associated with severe complications and pancreatic fistula as well as overall and disease-free survivals. RESULTS: There were 764 males (52,7%), and the median age was 64 years. A total of 781 patients (53.9%) developed at least one complication, among whom 317 (21.8%) were classified as Clavien-Dindo ≥ 3. A total of 114 (8.5%) patients had AP as the initial clinical manifestation of PDAC. This situation was not associated with any increase in the rates of postoperative fistula (21.2% vs 16.4%, P = 0.19), postoperative complications (57% vs 54.2%, P = 0.56), and 30 day mortality (2.6% vs 3.4%, P = 1). In multivariate analysis, AP did not correlate with postoperative complications or pancreatic fistula. The median length of follow-up was 22.4 months. The median overall survival after surgery was 29.9 months in the AP group and 30.5 months in the control group. Overall recurrence rate and local recurrence rate did not differ between groups. CONCLUSION: AP before PDAC resection did not impact postoperative morbidity and mortality, as well as recurrence rate and survival.

Reciprocal association between voting and the epidemic spread of COVID-19: observational and dynamic modeling study.

BACKGROUND: Whether voting is a risk factor for epidemic spread is unknown. Reciprocally, whether an epidemic can deter citizens from voting has not been often studied. We aimed to investigate such relationships for France during the coronavirus disease 19 (COVID-19) epidemic. METHODS: We performed an observational study and dynamic modelling using a sigmoidal mixed effects model. All hospitals with COVID-19 patients were included (18 March 2020-17 April 2020). Abstention rate of a concomitant national election was collected. RESULTS: Mean abstention rate in 2020 among departments was 52.5% ± 6.4% and had increased by a mean of 18.8% as compared with the 2014 election. There was a high degree of similarity of abstention between the two elections among the departments (P < 0.001). Among departments with a high outbreak intensity, those with a higher participation were not affected by significantly higher COVID-19 admissions after the elections. The sigmoidal model fitted the data from the different departments with a high degree of consistency. The covariate analysis showed that a significant association between participation and number of admitted patients was observed for both elections (2020: ß = -5.36, P < 1e-9 and 2014: ß = -3.15, P < 1e-6) contradicting a direct specific causation of the 2020 election. Participation was not associated with the position of the inflexion point suggesting no effect in the speed of spread. CONCLUSIONS: Our results suggest that the surrounding intensity of the COVID-19 epidemic in France did not have any local impact on participation to a national election. The level of participation had no impact on the spread of the pandemic.

Image-guided Percutaneous Fixation with Internal Cemented Screws of Impending Femoral Neck Pathologic Fractures in Patients with Metastatic Cancer: Safety, Efficacy, and Durability.

Background Prophylactic image-guided procedures performed by interventional radiologists for impending pathologic fractures are becoming more pertinent, as patients with metastatic cancer have extended overall survival because of advanced therapies. Purpose To evaluate the efficacy, safety, and palliative durability of collimated-beam CT-guided percutaneous fixation with internal cemented screws (FICS) for impending pathologic fractures of the femoral neck. Materials and Methods This single-institute retrospective study examined all patients with metastatic cancer treated between February 2010 and October 2019 with collimated-beam CT-guided percutaneous FICS procedures for preventive consolidation of impending femoral neck pathologic fractures. The short-term palliative efficacy was assessed through comparison of visual analog scale (VAS) scores before and 1 month after FICS. A review of cross-section imaging and clinic reports identified any procedural complications. Long-term consolidation efficacy was defined as the absence of any screw dislodgement or development of a pathologic fracture at completion of the study. The Wilcoxon test was used for the mean comparison of paired nonparametric variables. Results Sixty-one consecutive patients (mean age, 59 years ± 11 [standard deviation]; 35 women) underwent preventive FICS for consolidation of impending pathologic femoral neck fracture with a mean follow-up of 533 days ± 689. Two patients died of cancer within the first month. Complications were limited to three self-resolving hematomas. The mean VAS score decreased 1 month after FICS from 4.2 ± 3.2 to 1.8 ± 2.0 (P < .001). The long-term consolidation efficacy was 92% (54 of 59 patients), with three of 59 patients (5%) subsequently developing fractures despite FICS and an additional two of 59 patients (3%) with durable FICS undergoing definitive total hip arthroplasty surgery because of local tumor progression. Conclusion Percutaneous fixation with internal cemented screws as performed by the interventional radiologist is a safe nonsurgical treatment that provides an effective palliative result and durable prevention for impending pathologic fractures of the femoral neck. © RSNA, 2020 Online supplemental material is available for this article.

A new score based on biomarker values to predict the prognosis of locally advanced cervical cancer.

OBJECTIVE: To define a prognostic score based on pretreatment values of leucocyte, platelet and hemoglobin in locally advanced cervical cancer (LACC). MATERIAL AND METHODS: We conducted a prospective study of 238 patients for LACC with negative PET imaging in the para-aortic (PA) area and who were undergoing laparoscopic PA lymphadenectomies. All patients were treated with chemo-radiation and brachytherapy. RESULTS: Patients had clinical International Federation of Gynecology and Obstetrics stages IB2 (n = 76), IIA (n = 13), IIB (n = 122), III (n = 18) or IVA (n = 9). We identified three biological parameters (at the time of diagnosis) with three cut-offs which impacted disease free survival (DFS) and overall survival (OS): <12 g/dL for hemoglobin, >10,000/µL for leucocyte and >300 × 109/L for platelet. A score is calculated, as shown in the table below, by adding the scores of all three biological parameters together (with a maximum score of three). DFS at 36 months was 87.3% [78.3-97.4], 58% [45-74.6], 79.1% [71.1-88], 58% [45-74.6] and 56.8% [37.8-85.4] for scores of 0, 1, 2 and 3 respectively. OS at 36 months was 92.6% [84.9-100], 84% [76.6-92.1], 62.5% [48.9-79.9] and 67% [46.8-96] for scores of 0, 1, 2 and 3 respectively. CONCLUSION: This score includes three biomarkers with easily remembered cut-offs that allow us to identify, at the time of diagnosis, those patients with a high risk of relapse (scores of two or three) and those requiring dose escalation.

Long term follow-up of a large series of stage-II/III atypical proliferative serous ovarian tumors.

BACKGROUND: The aim of this study was to assess prognostic factors and implications on further management in a large series of stage-II or III Atypical Proliferative Serous Tumors (APST) with a long-term follow-up. PATIENTS AND METHODS: Patients with APSTs and peritoneal implants treated in, or referred to, our institution were retrospectively reviewed. Prognostic factors on invasive recurrence, disease-free (DFS) and overall survival (OS) were analyzed. RESULTS: Between 1971 and 2017, 212 patients were identified and followed (33 having invasive implants). After a median follow-up of 115 months, 70 recurrences were observed, 28 of them under the form of invasive disease. DFS at 5 years and 10 years was 73% and 62% respectively. The use of a conservative treatment (HR = 5.5[3.33-9.08], p < .0001), the presence of ≥3 peritoneal sites with implants (HR = 1.65[1.01-2.72], p = .045) were unfavorable prognostic factors for DFS. The presence of ≥3 peritoneal sites with implants (HR = 3.02[0.96-9.53], p = .049) and the presence of stromal microinvasion (HR = 3.19[1.12-9.1], p = .022) were unfavorable prognostic factors for OS. Non-conservative surgery (HR = 7[2.35-20.87], p = .0002), invasive implants (HR = 5.37[1.29-22.26], p = .013), and ≥ 3 peritoneal sites with implants (HR = 3.56 [1.11-11.39], p = .024) were identified as predictors of recurrence in the form of an invasive disease. Invasive implants were not associated with DFS (HR = 1.39[0.77-2.51], p = .27), nor OS (HR = 1.76[0.57-5.47], p = .32). CONCLUSION: After a long-term follow-up, type of peritoneal implants is no longer a prognostic factor for OS. Implants ≥3 peritoneal sites seem to impact significantly OS and then require a specific follow-up in this subgroup of patients.

The Postoperative Occurrence or Worsening of Diabetes Mellitus May Increase the Risk of Recurrence in Resected Pancreatic Neuroendocrine Tumors.

INTRODUCTION: The goal of this retrospective study was to investigate the potential link between diabetes mellitus (DM) and the recurrence of pancreatic neuroendocrine tumors (PanNET) following curative intent surgery. METHODS: We included patients who underwent surgical resection of nonmetastatic well-differentiated PanNET. Exacerbation of DM was defined as the postoperative occurrence of DM or worsening of preexisting DM. We explored the variables associated with PanNET recurrence-free survival (RFS). RFS was compared in a subset of patients with and without DM operated on by anatomical resection, after matching for the main prognostic factors. The impact of antidiabetic therapy on RFS was assessed. RESULTS: A total of 268 patients (median age 54.7, 40% men) were included. Most PanNET were sporadic (85%), G1 (61%), pT1/pT2 (79%), and pN0 (76%). Postoperative DM exacerbation occurred in 38 patients (14%), including 27 with new-onset DM. On multivariable analysis, DM exacerbation was independently associated with an increased risk of PanNET recurrence (HR 2.35, 95% CI [1.24-4.47], p = 0.009) after adjustment for age, multiplicity of tumors, grade, pT, and pN stages. Similar results were found when 27 patients with and 48 patients without DM exacerbation, matched for grade, pT stage and pN stage, were compared (HR 3.03, 95% CI [1.05-8.77], p = 0.032). The postoperative use of metformin tended to decrease the risk of recurrence (HR 0.59, 95% CI 0.24-1.47, p = 0.26). CONCLUSION: Patients with postoperative DM exacerbation may have an increased risk of PanNET recurrence. Closer follow-up might be beneficial in these patients. The protective role of metformin should be further explored.
