Cytoreductive Surgery and Intraperitoneal Chemotherapy in Advanced Serous Epithelial Ovarian Cancer: A 14-Year French Retrospective Single-Center Study of 124 Patients.

INTRODUCTION: Ovarian cancer (OC) is the most lethal gynecological cancer. Cytoreductive surgery (CRS) combined with hyperthermic intraperitoneal chemotherapy appears to increase survival, and normothermic intraperitoneal chemotherapy (IPC) could improve overall survival (OS). Furthermore, intraperitoneal epinephrine could decrease the toxicity of chemotherapy by decreasing the systemic absorption of chemotherapy. The goal of this study was to assess the effects of CRS and IPC with intraperitoneal epinephrine, as first-line therapy, on the survival of patients with serous epithelial OC (EOC) with peritoneal metastases. METHODS: A prospective monocentric database was retrospectively searched for all patients with advanced serous EOC treated by interval or consolidative CRS plus IPC with intraperitoneal epinephrine after neoadjuvant chemotherapy. OS and disease-free survival (DFS), postoperative complications, and prognostic factors were analyzed. RESULTS: From January 2003 to December 2017, 124 patients with serous EOC were treated with interval (n = 58) or consolidative (n = 66) complete CRS plus IPC with intraperitoneal epinephrine. The median follow-up was 77.8 months, the median OS was 60.8 months, and the median DFS was 21.2 months. In our multivariate analysis, a higher Peritoneal Cancer Index (PCI) and positive lymph node status resulted in worse OS, while higher World Health Organization score, higher PCI score, and positive lymph node status were risk factors for worse DFS. Grade 3 or higher surgical morbidity occurred in 27.42% of cases; only 3.2% had grade 3 renal toxicity and mortality was 0.8%. CONCLUSION: CRS and IPC with intraperitoneal epinephrine in stage III EOC offer good OS and DFS with acceptable morbidity and mortality rates.

Overall survival in patients with re-excision of positive microscopic margins of limb and trunk wall soft tissue sarcoma operated outside of a reference center: a nationwide cohort analysis.

BACKGROUND: This French nationwide NETSARC exhaustive prospective cohort aims to explore the impact of systematic re-excision (RE) as adjuvant care on overall survival (OS), local recurrence free survival (LRFS), and local and distant control (RFS) in patients with soft tissue sarcoma (STS) with positive microscopic margins (R1) after initial resection performed outside of a reference center. METHODS: Eligible patients had experienced STS surgery outside a reference center from 2010 to 2017, and had R1 margins after initial surgery. Characteristics and treatment comparisons used chi-square for categorical variables and Kruskall-Wallis test for continuous data. Survival distributions were compared in patients reexcised (RE) or not (No-RE) using a log-rank test. A Cox proportional hazard model was used for subgroup analysis. RESULTS: A total of 1,284 patients had experienced initial STS surgery outside NETSARC with R1 margins, including 1,029 patients with second operation documented. Among the latter, 698 patients experienced re-excision, and 331 were not re-excised. Characteristics were significantly different regarding patient age, tumor site, tumor size, tumor depth, and histotype in the population of patients re-excised (RE) or not (No-RE). The study identified RE as an independent favorable factor for OS (HR 0.36, 95%CI 0.23-0.56, p<0.0001), for LRFS (HR 0.45, 95%CI 0.36-0.56, p<0.0001), and for RFS (HR 0.35, 95%CI 0.26-0.46, p<0.0001). CONCLUSION: This large nationwide series shows that RE improved overall survival in patients with STS of extremities and trunk wall, with prior R1 resection performed outside of a reference center. RE as part of adjuvant care should be systematically considered.

Post-Transplantation Cytomegalovirus Infection Interplays With the Development of Anastomotic Biliary Strictures After Liver Transplantation.

Background: Anastomotic biliary stricture (ABS) remains the most frequent complication after liver transplantation (LT). This study aimed to identify new anastomotic biliary stricture risk factors, with a specific focus on postoperative events. Additionally, ABS management and impact on patient and graft survival were assessed. Methods: All consecutive patients who underwent LT with duct-to-duct anastomosis between 2010 and 2019 were included. All patients who died within 90 days after LT due to non-ABS-related causes were excluded. Results: Among 240 patients, 65 (27.1%) developed ABS after a median time of 142 days (range, 13-1265). Median follow-up was 49 months (7-126). Upon multivariable analysis, donor BMI (OR=0.509, p = 0.037), post-LT CMV primoinfection (OR = 5.244, p < 0.001) or reactivation (OR = 2.421, p = 0.015) and the occurrence of post-LT anastomotic biliary fistula (OR = 2.691, p = 0.021) were associated with ABS. Anastomotic technical difficulty did not independently impact the risk of ABS (OR = 1.923, p = 0.051). First-line ABS treatment was systematically endoscopic (100%), and required a median of 2 (range, 1-11) procedures per patient. Repeat LT was not required in patients developing ABS. The occurrence of ABS was not associated with overall patient survival (p = 0.912) nor graft survival (p = 0.521). Conclusion: The risk of developing ABS after LT seems driven by the occurrence of postoperative events such as CMV infection and anastomotic fistula. In this regard, the role of CMV prophylaxis warrants further investigations.

Delayed return of gastrointestinal function after hepatectomy in an ERAS program: incidence and risk factors.

BACKGROUND: Delayed return of gastrointestinal function (DGIF) after hepatectomy can involve increased morbidity and prolonged hospital stay. Yet, data on incidence and risks factors are lacking. METHODS: All consecutive patients who underwent hepatectomy between June 2018 and December 2020 were included. All patients were included in an enhanced recovery after surgery (ERAS) program. DGIF was defined by the need for nasogastric tube (NGT) insertion after surgery. DGIF risk factors were identified. RESULTS: Overall, 206 patients underwent hepatectomy. DGIF occurred in 41 patients (19.9%) after a median time of 2 days (range, 1-14). Among them, 6 patients (14.6%) developed aspiration pneumonia, of which one required ICU for mechanical ventilation. DGIF developed along with an intraabdominal complication in 7 patients (biliary fistula, n = 5; anastomotic fistula, n = 1; adhesive small bowel obstruction, n = 1). DGIF was associated with significantly increased severe morbidity rate (p = 0.001), prolonged time to normal food intake (p < 0.001) and hospital stay (p < 0.001) and significantly decreased overall compliance rate (p = 0.001). Independent risk factors of DGIF were age (p < 0.001), vascular reconstruction (p = 0.007), anaesthetic induction using volatiles (p = 0.003) and epidural analgesia (p = 0.004). Using these 4 variables, a simple DGIF risk score has been developed allowing patient stratification in low-, intermediate- and high-risk groups. CONCLUSION: DGIF after hepatectomy was frequently observed and significantly impacted postoperative outcomes. Identifying risk factors remains critical for preventing its occurrence.

Half of Postoperative Deaths After Cytoreductive Surgery and Hyperthermic Intraperitoneal Chemotherapy Could be Preventable: A French Root Cause Analysis on 5562 Patients.

OBJECTIVE: To perform a retrospective root-cause analysis of postoperative death after CRS and HIPEC procedures. BACKGROUND: The combination of CRS and HIPEC is an effective therapeutic strategy to treat peritoneal surface malignancies, however it is associated with significant postoperative mortality. METHODS: All patients treated with a combination of CRS and HIPEC between January 2009 and December 2018 in 22 French centers and died in the hospital, were retrospectively analyzed. Perioperative data of the 101 patients were collected by a local senior surgeon with a sole junior surgeon. Three independent experts investigated the typical root cause of death and provided conclusions on whether postoperative death was preventable (PREV group) or not (NON-PREV group). A typical root cause of preventable postoperative death was classified on a cause-and-effect diagram. RESULTS: Of the 5562 CRS+HIPEC procedures performed, 101 in-hospital deaths (1.8%) were identified, of which a total of 18 patients of 70 years old and above and 20 patients with ASA score of 3. Etiology of peritoneal disease was mainly colorectal. A total of 54 patients (53%) were classified in the PREV group and 47 patients (47%) in the NON-PREV group. The results of the study show that in the PREV group, WHO performance status 1-2 was more frequent and the Median Peritoneal Cancer Index was higher compared with those of the NON-PREV group. The cause of death in the PREV group was classified as: (i) preoperatively for debatable indication (59%), (ii) intraoperatively (30%) and (iii) postoperatively in 17 patients (31%). A multifactorial cause of death was found in 11 patients (20%). CONCLUSION: More than half of the postoperative deaths after combined CRS and HIPEC may be preventable, mainly by following guidelines regarding preoperative selection of the patients and adequate intraoperative decisions.

Inflammatory markers as early predictors of infection after colorectal surgery: the same cut-off values in laparoscopy and laparotomy?

PURPOSE: C-reactive protein and procalcitonin are reliable early predictors of infection after colorectal surgery. However, the inflammatory response is lower after laparoscopy as compared to open surgery. This study analyzed whether a different cutoff value of inflammatory markers should be chosen according to the surgical approach. METHODS: A prospective, observational study included consecutive patients undergoing elective colorectal surgery in three academic centers. All infections until postoperative day (POD) 30 were recorded. The inflammatory markers were analyzed daily until POD 4. Areas under the ROC curve and diagnostic values were calculated in order to assess their accuracy as a predictor of intra-abdominal infection. RESULTS: Five-hundred-one patients were included. The incidence of intra-abdominal infection was 11.8%. The median levels of C-reactive protein (CRP) and procalcitonin (PCT) were lower in the laparoscopy group at each postoperative day (p < 0.0001). In patients without intra-abdominal infection, they were also lower in the laparoscopy group (p = 0.0036) but were not different in patients presenting with intra-abdominal infections (p = 0.3243). In the laparoscopy group, CRP at POD 4 was the most accurate predictor of overall and intra-abdominal infection (AUC = 0.775). With a cutoff of 100 mg/L, it yielded 95.7% negative predictive value, 75% sensitivity, and 70.3% specificity for the detection of intra-abdominal infection. CONCLUSION: The impact of infection on inflammatory markers is more important than that of the surgical approach. Defining a specific cutoff value for early discharge according to the surgical approach is not justified. A patient with CRP values lower than 100 mg/L on POD 4 can be safely discharged.

Diagnostic Accuracy of Inflammatory Markers As Early Predictors of Infection After Elective Colorectal Surgery: Results From the IMACORS Study.

BACKGROUND: Intra-abdominal infections are frequent and life-threatening complications after colorectal surgery. An early detection could diminish their clinical impact and permit safe early discharge. OBJECTIVE: This study aimed to find the most accurate marker for the detection of postoperative intra-abdominal infection and the appropriate moment to measure it. METHODS: A prospective, observational study was conducted in 3 centers. Consecutive patients undergoing elective colorectal surgery with anastomosis were included. C-reactive protein and procalcitonin were measured daily until the fourth postoperative day. Postoperative infections were recorded according to the definitions of the Centres for Diseases Control. The areas under the receiver operating characteristic curve were analyzed and compared to assess the diagnostic accuracy of each marker. RESULTS: Five-hundred and one patients were analyzed. The incidence of intra-abdominal infection was 11.8%, with 24.6% of patients presenting at least one infectious complication. Overall mortality was 1.2%. At the fourth postoperative day, C-reactive protein was more discriminating than procalcitonin for the detection of intra-abdominal infection (areas under the ROC curve: 0.775 vs 0.689, respectively, P = 0.03). Procalcitonin levels showed wide dispersion. For the detection of all infectious complications, C-reactive protein was also significantly more accurate than procalcitonin on the fourth postoperative day (areas under the ROC curve: 0.783 vs 0.671, P = 0.0002). CONCLUSIONS: C-reactive protein is more accurate than procalcitonin for the detection of infectious complications and should be systematically measured at the fourth postoperative day. It is a useful tool to ensure a safe early discharge after elective colorectal surgery.

Preoperative inflammation increases the risk of infection after elective colorectal surgery: results from a prospective cohort.

BACKGROUND: Septic complications after colorectal surgery are frequent and sometimes life threatening. It is well known that inflammation impairs the healing process. It has been suggested that preoperative ongoing inflammation could increase the risk of postoperative infections. This study aimed to elucidate the role of preoperative inflammation on postoperative infectious complications and to understand if, through biological markers, it is possible to identify preoperatively patients at higher risk of infection. METHODS: A prospective, observational study was conducted in three centers from November 2011 to April 2014. Consecutive patients undergoing elective colorectal surgery with anastomosis were included. Any ongoing infection was an exclusion criterion. C-reactive protein, albumin, prealbumin, and procalcitonin plasma levels were measured preoperatively. Postoperative infections were recorded according to the definitions of the Centers for Diseases Control. The areas under the receiver operating characteristic curve were analyzed and compared to assess the accuracy of each preoperative marker. RESULTS: Four-hundred and seventy two patients were analyzed. Infectious complications occurred in 118 patients (25 %) and mortality in 6 patients (1.3 %). In the univariate analysis, preoperative C-reactive protein and albuminemia were found significantly associated with postoperative infectious complications (P = 0.008 and P = 0.0002, respectively). Areas under the ROC curve for preoperative C-reactive protein and albuminemia were 0.57and 0.62, respectively. CONCLUSIONS: This study confirms the association between preoperative inflammatory activity, hypoalbuminemia, and the onset of infections after surgery. Trials aiming to decrease the inflammatory activity before surgery in order to prevent postoperative complications are warranted.

Liver resection for colorectal metastases: results and prognostic factors with 10-year follow-up.

PURPOSE: Actual 5-year survival rates after resection of colorectal liver metastases (CLM) are 25-45%, whereas 10-year survival rates are extrapolated from survival curves. Few studies have reported long-term survivors with 10 years of actual follow-up. Therefore, no recurrences occurring after 10-plus years have been reported. The aim of our study was to analyze actual 10-year survival rates and prognostic factors. METHODS: Clinical data of patients with CLM who had undergone first liver resection in our center between January 1990 and December 2000 were retrospectively analyzed. RESULTS: Eighty-nine patients of mean age 64 years were studied. Three patients were excluded from the study: one because of postoperative death, and two from being lost to follow-up. All other subjects had a potential 10-year follow-up. Only 33% patients received perioperative chemotherapy. The actual 10-year overall and disease-free survival rate were 22 and 19%, respectively. Poor prognostic factors were disease-free interval less than 1 year, wedge liver resection, clinical risk score>2, segment 1 CLM location, and peritumoral lymphangitis. Good prognostic factors were tumors having mucinous components in primary tumor and CLM located in the right lobe. CONCLUSIONS: With actual long-term follow-up for 10 years, disease-free survival rate is 19% and mainly depends on surgical management. Recurrence continues to occur more than 5 years after liver resection for CLM; cure cannot be assumed at this time. Clinical risk score is a good predictor of cure and should be taken into account when choosing perioperative treatment.

Improved Metastatic-Free Survival after Systematic Re-Excision Following Complete Macroscopic Unplanned Excision of Limb or Trunk Soft Tissue Sarcoma.

BACKGROUND: Whether re-excision (RE) of a soft tissue sarcoma (STS) of limb or trunk should be systematized as adjuvant care and if it would improve metastatic free survival (MFS) are still debated. The impact of resection margins after unplanned macroscopically complete excision (UE) performed out of a NETSARC reference center or after second resection was further investigated. METHODS: This large nationwide series used data from patients having experienced UE outside of a reference center from 2010 to 2019, collected in a French nationwide exhaustive prospective cohort NETSARC. Patient characteristics and survival distributions in patients reexcised (RE) or not (No-RE) are reported. Multivariate Cox proportional hazard model was conducted to adjust for classical prognosis factors. Subgroup analysis were performed to identify which patients may benefit from RE. RESULTS: Out of 2371 patients with UE for STS performed outside NETSARC reference centers, 1692 patients were not reviewed by multidisciplinary board before treatment decision and had a second operation documented. Among them, 913 patients experienced re-excision, and 779 were not re-excised. Characteristics were significantly different regarding patient age, tumor site, size, depth, grade and histotype in patients re-excised (RE) or not (No-RE). In univariate analysis, final R0 margins are associated with a better MFS, patients with R1 margins documented at first surgery had a better MFS as compared to patients with first R0 resection. The study identified RE as an independent favorable factor for MFS (HR 0.7, 95% CI 0.53-0.93; p = 0.013). All subgroups except older patients (>70 years) and patients with large tumors (>10 cm) had superior MFS with RE. CONCLUSIONS: RE might be considered in patients with STS of limb or trunk, with UE with macroscopic complete resection performed out of a reference center, and also in originally defined R0 margin resections, to improve LRFS and MFS. Systematic RE should not be advocated for patients older than 70 years, or with tumors greater than 10 cm.

Spigelian hernia: CT findings and clinical relevance.

OBJECTIVE: The purpose of our study was to evaluate the clinical relevance of preoperative CT in distinguishing between the two subtypes of spigelian hernia (SH). MATERIALS AND METHODS: We reviewed retrospectively the CT images of 35 patients. The patients were divided into two groups on the basis of the SH subtype: interstitial SH group (n = 15) and subcutaneous SH group (n = 20). Clinical characteristics of patients and CT findings were analyzed. Bowel ischemia on surgery was also noted. RESULTS: Sixteen right hernias and 19 left hernias were observed. Fifteen interstitial SH (43%) and 20 subcutaneous SH (57%) were found. No type of content showed a statistically significant association with one or other subtype of SH. Nine of the 26 patients presenting with SH with SB content showed signs of SBO on CT. Closed-loop SBO on CT was present in 5 of the 26 patients with SB content. An interstitial SH was observed in all of these 5 patients (p = 0.039). Surgery was performed on 10 patients. Bowel ischemia was found on surgery in 4 patients and showed no statistically significant association with a particular subtype of SH (p = 0.6). CONCLUSION: Our study shows the importance of performing CT in SH. CT provides the diagnosis of SH, shows SH content, and demonstrates the presence of SBO or closed-loop SBO. Moreover, the distinction between the two subtypes of SH on CT appears to be of clinical relevance since closed-loop SBO is statistically associated with interstitial SH and the optimal surgical approach may differ.

Liver Transplantation Using Allografts With Recent Liver Blunt Trauma: A Nationwide Audit From the French CRISTAL Biomedicine Agency Registry.

BACKGROUND: In the current setting of organ shortage, brain-dead liver donors with recent liver trauma (RLT) represent a potential pool of donors. Yet, data on feasibility and safety of liver transplantation (LT) using grafts with RLT are lacking. METHODS: All liver grafts from brain-dead donors with RLT proposed for LT between 2010 and 2018 were identified from the nationwide CRISTAL registry of the Biomedicine Agency. The current study aimed at evaluating 1-y survival as the primary endpoint. RESULTS: Among 11 073 LTs, 142 LTs (1.3%) using grafts with RLT were performed. These 142 LTs, including 23 split LTs, were performed from 131 donors (46.1%) of 284 donors with RLT proposed for LT. Transplanted grafts were procured from donors with lower liver enzymes levels ( P < 0.001) and less advanced liver trauma according to the American Association for the Surgery of Trauma liver grading system ( P < 0.001) compared with not transplanted grafts. Before allocation procedures, 20 (7%) of 284 donors underwent damage control intervention. During transplantation, specific liver trauma management was needed in 19 patients (13%), consisting of local hemostatic control (n = 15), partial hepatic resection on back-table (n = 3), or perihepatic packing (n = 1). Ninety-day mortality and severe morbidity rates were 8.5% (n = 12) and 29.5% (n = 42), respectively. One-year overall and graft survival rates were 85% and 81%, and corresponding 5-y rates were 77% and 72%, respectively. CONCLUSIONS: Using liver grafts from donors with RLT seems safe with acceptable long-term outcomes. All brain-dead patients with multiorgan trauma, including liver injury, should be considered for organ allocation.

Wound Healing versus Metastasis: Role of Oxidative Stress.

Many signaling pathways, molecular and cellular actors which are critical for wound healing have been implicated in cancer metastasis. These two conditions are a complex succession of cellular biological events and accurate regulation of these events is essential. Apart from inflammation, macrophages-released ROS arise as major regulators of these processes. But, whatever the pathology concerned, oxidative stress is a complicated phenomenon to control and requires a finely tuned balance over the different stages and responding cells. This review provides an overview of the pivotal role of oxidative stress in both wound healing and metastasis, encompassing the contribution of macrophages. Indeed, macrophages are major ROS producers but also appear as their targets since ROS interfere with their differentiation and function. Elucidating ROS functions in wound healing and metastatic spread may allow the development of innovative therapeutic strategies involving redox modulators.

Comparison of Molecular and Histologic Ultrastaging Methods in Sentinel Lymph Node Analysis from Clinical Stage II Colon Cancers.

Various studies have demonstrated that occult metastases may be present in patients with clinical stage II colon cancer. The objective of this prospective investigation was to compare the performance of molecular analysis and histologic ultrastaging in detecting occult metastases in sentinel lymph nodes (SLNs). SLNs were collected ex vivo during surgery in 29 patients. Quantitative reverse-transcription polymerase chain reaction (qRT-PCR) assays were constructed. The results were compared with histologic ultrastaging analysis by hemalum and eosin stain and immunohistochemistry on step serial sections. At least 1 SLN was identified in 76% of the cases. The first hemalum and eosin section identified metastases in 23% of the 22 SLNs. Immunohistochemistry identified isolated tumor cells in 24% of the remaining 17 cases. An overall 73% of the SLNs analyzed by qRT-PCR were positive. Four of them were negative for ultrastaging analysis. qRT-PCR is a powerful tool for the detection of occult metastases in colorectal SLN and seems to be more sensitive than histologic ultrastaging analysis. A larger prospective cohort study is necessary to provide further evidence.

Transient portal venous gas associated with reversible non-occlusive mesenteric ischemia: A case report.

OBJECTIVES: To report the utility of abdominal ultrasonography (US) to identify the presence of portal venous gas (PVG) during non-occlusive mesenteric ischemia (NOMI), and to follow the disappearance of portal venous gas after resolution of the NOMI. DATA SOURCES: This was a clinical observation of a patient, with images of abdominal computed tomography (CT), and a video of portal venous gas identified by ultrasonography. DATA SYNTHESIS: We describe the case of an adult patient admitted to our ICU for NOMI developing 48h after cardiac surgery. Medical intensive care associated with jejunal resection and vacuum-assisted closure led to rapid recovery. Three weeks later, the patient presented acute pulmonary edema, and developed a new episode of NOMI that was suspected by identification of PVG on US, and then confirmed on abdominal CT. The patient rapidly improved after orotracheal intubation and treatment of pulmonary edema. A second US performed 9h later showed disappearance of PVG. The laparotomy performed 10h after the first US did not find evidence of small bowel or colon ischemia. The postoperative period was uneventful. CONCLUSIONS: US is a useful tool for the detection of PVG in critically ill patients, prompting suspicion of AMI. PVG can be observed at the early phase of AMI, even before irreversible transmural gut ischemia; transient PVG that disappears rapidly (within several hours) may suggest resolution of the NOMI.

Does IV contrast extravasation on CT in anticoagulant-related rectus sheath and iliopsoas hematoma predict hematoma expansion and patient outcomes?

OBJECTIVE: The purpose of the study was to evaluate if IV contrast extravasation on CT in anticoagulant-related rectus sheath and iliopsoas hematoma predict hematoma expansion and patient outcomes. MATERIALS AND METHODS: All patients presented with anticoagulation-related spontaneous IP hematoma or RS hematoma and who underwent contrast-enhanced CT exploration, with injection of a contrast material, from January 2012 to January 2015 in our institution were included in this study. Considering the retrospective nature of our study, our institutional review board judged our study to be exempted from ethical approval and no patient consent was required. Computed tomography (CT) images were retrospectively analyzed blindly of the evolution and treatment of hematomas. The type of muscle involved; the presence of contrast extravasation after contrast injection; the volume of the hematoma, as well as, clinical and biological results (hemoglobin value g/dL); and for each patient, the type of anticoagulation used, patient's treatment and outcomes were noted. The analyses were conducted using R 3.1.0. All statistical tests were 2-sided, and probability values <0.05 were regarded as significant. RESULTS: Sixty-eight patients were reviewed. Among 68 patients, 44 (65%) patients presented spontaneous IP hematoma and 24/68 (35%) a RS hematoma. There were 37 men (54%) and 31 (46%) women, ranging from 39 to 93 years with a median age of 75 years. Hemodynamic instability was statistically associated with IP hematomas and large volume of hematoma (p < 0.001). Only 15 patients had follow-up CT, 10 without and with IV contrast, 2 with IV contrast only, and 3 without contrast. Follow-up CT was performed from J0 to J8. Detection of contrast extravasation did not appear related to hemodynamically instability (p = 0.35), to a neurological deficit (p = 1), or to the increase in the volume of the hematoma on follow-up CT (p = 0.81). The different types of anticoagulant were not related to muscular type more than the other (p = 0.9). Among anticoagulant therapy, only vitamin K antagonist therapy was statistically associated with surgery (p = 0.04). CONCLUSION: CT extravasation of contrast material in IP and RS hematoma does not appear to be related with clinical criteria of severity, and therefore should not be solely considered as a radiological decision criteria.

Prognostic value of health-related quality of life for death risk stratification in patients with unresectable glioblastoma.

Glioblastoma is the most common malignant brain tumor in adults. Baseline health-related quality of life (HRQoL) is a major subject of concern for these patients. We aimed to assess the independent prognostic value of HRQoL in unresectable glioblastoma (UGB) patients for death risk stratification. One hundred and thirty-four patients with UGB were enrolled from the TEMAVIR trial. HRQoL was evaluated at baseline using the EORTC QLQ-C30 and BN20 brain cancer module. Clinical and HRQoL parameters were evaluated in univariable and multivariable Cox analysis as prognostic factors for overall survival (OS). Performance assessment and internal validation of the final model were evaluated with Harrel's C-index, calibration plot, and bootstrap sample procedure. Two OS independent predictors were identified: future uncertainty and sensitivity deficit. The final model exhibited good calibration and acceptable discrimination (C statistic = 0.63). The internal validity of the model was verified with robust uncertainties around the hazard ratio. The prognostic score identified three groups of patients with distinctly different risk profiles with median OS estimated at 16.2, 9.2, and 4.5 months. We demonstrated the additional prognostic value of HRQoL in UGB for death risk stratification and provided a score that may help to guide clinical management and stratification in future clinical trials.
