RESUMO
PURPOSE: Single large hepatocellular carcinoma >5cm (SLHCC) traditionally requires a major liver resection. Minor resections are often performed with the goal to reduce morbidity and mortality. Aim of the study was to establish if a major resection should be considered the best treatment for SLHCC or a more limited resection should be preferred. METHODS: A multicenter retrospective analysis of the HE.RC.O.LE.S. Group register was performed. All collected patients with surgically treated SLHCC were divided in 5 groups of treatment (major hepatectomy, sectorectomy, left lateral sectionectomy, segmentectomy, non-anatomical resection) and compared for baseline characteristics, short and long-term results. A propensity-score weighted analysis was performed. RESULTS: 535 patients were enrolled in the study. Major resection was associated with significantly increased major complications compared to left lateral sectionanectomy, segmentectomy and non-anatomical resection (all p<0.05) and borderline significant increased major complications compared to sectorectomy (p=0.08). Left lateral sectionectomy showed better overall survival compared to major resection (p=0.02), while other groups of treatment resulted similar to major hepatectomy group for the same item. Absence of oncological benefit after major resection and similar outcomes among the 5 groups of treatment was confirmed even in the sub-population excluding patients with macrovascular invasion. CONCLUSION: Major resection was associated to increased major post-operative morbidity without long-term survival benefit; when technically feasible and oncologically adequate, minor resections should be preferred for the surgical treatment of SLHCC.

Background and Objectives: Serum alpha-fetoprotein (AFP) is a recognized affordable oncological marker in patients with hepatocellular carcinoma (HCC). However, AFP's prognostic role has been assessed mainly after specific treatments, and no unanimously recognized cut-offs have been identified. The aim of this study is to investigate the prognostic role of different basal AFP cut-offs on survival and HCC course. Materials and Methods: In this single-center, retrospective study, all patients newly diagnosed with HCC between January 2009 and December 2021 were prospectively enrolled. Only patients suitable for curative HCC treatments were included in the analyses. Patients were stratified according to AFP cut-offs of 20, 200, 400, and 1000 ng/mL, which were correlated with survival outcomes and clinical parameters. Results: A total of 266 patients were analyzed, with a median follow-up time of 41.5 months. Median overall survival (OS) of all cohort was 43 months. At the multivariate Cox-regression analysis, AFP value ≥ 1000 ng/mL correlated with impaired OS (1-year OS: 67% vs. 88%, 5-year OS: 1% vs. 43%; p = 0.005); other risk factors were tumor dimension ≥ 5 cm (HR 1.73; p = 0.002), Child-Pugh class B-C (HR 1.72; p = 0.002), BCLC stage A (vs. 0) (HR 2.4; p = 0.011), and malignant portal vein thrombosis (HR 2.57; p = 0.007). AFP ≥ 1000 ng/mL was also associated with a reduced recurrence-free survival (HR 2.0; p = 0.038), while starting from AFP ≥ 20 ng/mL, a correlation with development of HCC metastases over time (HR 3.5; p = 0.002) was seen. AFP values ≥ 20 ng/mL significantly correlated with tumor size and higher histological grading; starting from AFP values ≥ 400 ng/mL, a significant correlation with Child-Pugh class B-C and female gender was also observed. Conclusions: Basal AFP correlates with relevant outcomes in patients with HCC. It could help identify patients at a higher risk of worse prognosis who might benefit from personalized surveillance and treatment programs. Prospective studies are needed to confirm these results.

Hepatocellular carcinoma typically metastasizes within the liver and may involve extrahepatic sites such as the lungs, adrenal glands, and bones at advanced stages. However, hepatocellular carcinoma metastasis to the thyroid is very uncommon and tumor-to-tumor metastasis from a hepatocellular cancer to a thyroid neoplasm is extremely rare. In this report, we present a case of a 70-year-old man with a hepatocellular carcinoma metastasizing to oncocytic thyroid carcinoma, emphasizing the importance of clinical history and of a multidisciplinary approach, as well as the usefulness of site-specific immunohistochemical markers, in diagnosing and managing cases of Rosai's metastasis, especially when donor and recipient neoplasms share similar histologic features.

OBJECTIVE: To evaluate the effect of a liver transplantation (LT) program on the outcomes of resectable hepatocellular carcinoma (HCC). BACKGROUND: Surgical treatment of HCC includes both hepatic resection (HR) and LT. However, the presence of cirrhosis and the possibility of recurrence make the management of this disease complex and probably different according to the presence of a LT program. METHODS: Patients undergoing HR for HCC between January 2005 and December 2019 were identified from a national database of HCC. The main study outcomes were major surgical complications according to the Comprehensive Complication Index, posthepatectomy liver failure (PHLF), 90-day mortality, overall survival, and disease-free survival. Secondary outcomes were salvage liver transplantation (SLT) and postrecurrence survival. RESULTS: A total of 3202 patients were included from 25 hospitals over the study period. Three of 25 (12%) had an LT program. The presence of an LT program within a center was associated with a reduced probability of PHLF (odds ratio=0.38) but not with overall survival and disease-free survival. There was an increased probability of SLT when HR was performed in a transplant hospital (odds ratio=12.05). Among transplant-eligible patients, those who underwent LT had a significantly longer postrecurrence survival. CONCLUSIONS: This study showed that the presence of a LT program was associated with decreased PHLF rates and an increased probability to receive SLT in case of recurrence.

BACKGROUND: Despite second-line transplant(SLT) for recurrent hepatocellular carcinoma(rHCC) leads to the longest survival after recurrence(SAR), its real applicability has never been reported. The aim was to compare the SAR of SLT versus repeated hepatectomy and thermoablation(CUR group). METHODS: Patients were enrolled from the Italian register HE.RC.O.LE.S. between 2008 and 2021. Two groups were created: CUR versus SLT. A propensity score matching (PSM) was run to balance the groups. RESULTS: 743 patients were enrolled, CUR = 611 and SLT = 132. Median age at recurrence was 71(IQR 6575) years old and 60(IQR 53-64, p < 0.001) for CUR and SLT respectively. After PSM, median SAR for CUR was 43 months(95%CI = 37 - 93) and not reached for SLT(p < 0.001). SLT patients gained a survival benefit of 9.4 months if compared with CUR. MilanCriteria(MC)-In patients were 82.7% of the CUR group. SLT(HR 0.386, 95%CI = 0.23 - 0.63, p < 0.001) and the MELD score(HR 1.169, 95%CI = 1.07 - 1.27, p < 0.001) were the only predictors of mortality. In case of MC-Out, the only predictor of mortality was the number of nodules at recurrence(HR 1.45, 95%CI= 1.09 - 1.93, p = 0.011). CONCLUSION: It emerged an important transplant under referral in favour of repeated hepatectomy or thermoablation. In patients with MC-Out relapse, the benefit of SLT over CUR was not observed.

OBJECTIVE: The aim of the study was to compare SURG vs SOR regarding the OS and progression-free survival (PFS) in a real-world clinical scenario. BACKGROUND DATA: The treatment for advanced nonmetastatic HCC belonging to the Barcelona Clinic Liver Cancer stage C (BCLC C) is still controversial. METHODS: BCLC C patients without extrahepatic spread and tumoral invasion of the main portal trunk were considered. Surgical patients were obtained from the HE.RC.O.LE.S. Register, whereas sorafenib patients were obtained from the ITA.LI.CA register The inverse probability weighting (IPW) method was adopted to balance the confounders between the 2 groups. RESULTS: Between 2008 and 2019, 478 patients were enrolled: 303 in SURG and 175 in SOR group. Eastern Cooperative Oncological Group Performance Status (ECOG-PS), presence of cirrhosis, steatosis, Child-Pugh grade, hepatitis B virus and hepatitis C virus, alcohol intake, collateral veins, bilobar disease, localization of the tumor thrombus, number of nodules, alpha-fetoprotein, age, and Charlson Comorbidity index were weighted by IPW to create two balanced pseudo-populations: SURG = 374 and SOR = 263. After IPW, 1-3-5âyears OS was 83.6%, 68.1%, 55.9% for SURG, and 42.3%, 17.8%, 12.8% for SOR (P < 0.001). Similar trends were observed after subgrouping patients by ECOG-PS = 0 and ECOG-PS >0, and by the intrahepatic location of portal vein invasion. At Cox regression, sorafenib treatment (hazard ratio 4.436; 95% confidence interval 3.19-6.15; P < 0.001) and Charlson Index (hazard ratio 1.162; 95% confidence interval 1.06-1.27; P = 0.010) were the only independent predictors of mortality. PFS at 1-3-5âyears were 65.9%, 40.3%, 24.3% for SURG and 21.6%, 3.5%, 2.9% for SOR (P = 0.007). CONCLUSIONS: In BCLC C patients without extrahepatic spread but with intrahepatic portal invasion, liver resection, if feasible, was followed by better OS and PFS compared with sorafenib.

BACKGROUND: Benchmark analysis for open liver surgery for cirrhotic patients with hepatocellular carcinoma (HCC) is still undefined. METHODS: Patients were identified from the Italian national registry HE.RC.O.LE.S. The Achievable Benchmark of Care (ABC) method was employed to identify the benchmarks. The outcomes assessed were the rate of complications, major comorbidities, post-operative ascites (POA), post-hepatectomy liver failure (PHLF), 90-day mortality. Benchmarking was stratified for surgical complexity (CP1, CP2 and CP3). RESULTS: A total of 978 of 2698 patients fulfilled the inclusion criteria. 431 (44.1%) patients were treated with CP1 procedures, 239 (24.4%) with CP2 and 308 (31.5%) with CP3 procedures. Patients submitted to CP1 had a worse underlying liver function, while the tumor burden was more severe in CP3 cases. The ABC for complications (13.1%, 19.2% and 28.1% for CP1, CP2 and CP3 respectively), major complications (7.6%, 11.1%, 12.5%) and 90-day mortality (0%, 3.3%, 3.6%) increased with the surgical difficulty, but not POA (4.4%, 3.3% and 2.6% respectively) and PHLF (0% for all groups). CONCLUSION: We propose benchmarks for open liver resections in HCC cirrhotic patients, stratified for surgical complexity. The difference between the benchmark values and the results obtained during everyday practice reflects the room for potential growth, with the aim to encourage constant improvement among liver surgeons.

BACKGROUND: We aimed to evaluate, in a large Western cohort, perioperative and long-term oncological outcomes of salvage hepatectomy (SH) for recurrent hepatocellular carcinoma (rHCC) after primary hepatectomy (PH) or locoregional treatments. METHODS: Data were collected from the Hepatocarcinoma Recurrence on the Liver Study Group (He.RC.O.Le.S.) Italian Registry. After 1:1 propensity score-matched analysis (PSM), two groups were compared: the PH group (patients submitted to resection for a first HCC) and the SH group (patients resected for intrahepatic rHCC after previous HCC-related treatments). RESULTS: 2689 patients were enrolled. PH included 2339 patients, SH 350. After PSM, 263 patients were selected in each group with major resected nodule median size, intraoperative blood loss and minimally invasive approach significantly lower in the SH group. Long-term outcomes were compared, with no difference in OS and DFS. Univariate and multivariate analyses revealed only microvascular invasion as an independent prognostic factor for OS. CONCLUSION: SH proved to be equivalent to PH in terms of safety, feasibility and long-term outcomes, consistent with data gathered from East Asia. In the awaiting of reliable treatment-allocating algorithms for rHCC, SH appears to be a suitable alternative in patients fit for surgery, regardless of the previous therapeutic modality implemented.

BACKGROUND: Management of recurrence after surgery for hepatocellular carcinoma (rHCC) is still a debate. The aim was to compare the Survival after Recurrence (SAR) of curative (surgery or thermoablation) versus palliative (TACE or Sorafenib) treatments for patients with rHCC. METHODS: This is a multicentric Italian study, which collected data between 2007 and 2018 from 16 centers. Selected patients were then divided according to treatment allocation in Curative (CUR) or Palliative (PAL) Group. Inverse Probability Weighting (IPW) was used to weight the groups. RESULTS: 1,560 patients were evaluated, of which 421 experienced recurrence and were then eligible: 156 in CUR group and 256 in PAL group. Tumor burden and liver function were weighted by IPW, and two pseudo-population were obtained (CUR = 397.5 and PAL = 415.38). SAR rates at 1, 3 and 5 years were respectively 98.3%, 76.7%, 63.8% for CUR and 91.7%, 64.2% and 48.9% for PAL (p = 0.007). Median DFS was 43 months (95%CI = 32-74) for CUR group, while it was 23 months (95%CI = 18-27) for PAL (p = 0.017). Being treated by palliative approach (HR = 1.75; 95%CI = 1.14-2.67; p = 0.01) and having a median size of the recurrent nodule>5 cm (HR = 1.875; 95%CI = 1.22-2.86; p = 0.004) were the only predictors of mortality after recurrence, while time to recurrence was the only protective factor (HR = 0.616; 95%CI = 0.54-0.69; p<0.001). CONCLUSION: Curative approaches may guarantee long-term survival in case of recurrence.

OBJECTIVE: The aim of this study was to evaluate correlation between centers' volume and incidence of failure to rescue (FTR) following liver resection for hepatocellular carcinoma (HCC). SUMMARY BACKGROUND DATA: FTR, defined as the probability of postoperative death among patients with major complication, has been proposed to assess quality of care during hospitalization. Perioperative management is challenging in cirrhotic patients and the ability to recognize and treat a complication may be fundamental to rescue patients from the risk of death. METHODS: Patients undergoing liver resection for HCC between 2008 and 2018 in 18 Centers enrolled in the He.Rc.O.Le.S. Italian register. Early results included major complications (Clavien ≥3), 90-day mortality, and FTR and were analyzed according to center's volume. RESULTS: Among 1935 included patients, major complication rate was 9.4% (8.6%, 12.3%, and 7.0% for low-, intermediate- and high-volume centers, respectively, P = 0.001). Ninety-day mortality rate was 2.6% (3.7%, 4.2% and 0.9% for low-, intermediate- and high-volume centers, respectively, P < 0.001). FTR was significantly higher at low- and intermediate-volume centers (28.6% and 26.5%, respectively) than at high-volume centers (6.1%, P = 0.002). Independent predictors for major complications were American Society of Anesthesiologists (ASA) >2, portal hypertension, intraoperative blood transfusions, and center's volume. Independent predictors for 90-day mortality were ASA >2, Child-Pugh score B, BCLC stage B-C, and center's volume. Center's volume and BCLC stage were strongly associated with FTR. CONCLUSIONS: Risk of major complications and mortality was related with comorbidities, cirrhosis severity, and complexity of surgery. These factors were not correlated with FTR. Center's volume was the only independent predictor related with severe complications, mortality, and FTR.

The activating natural cytotoxicity receptor NKp30 is critical for natural killer (NK) cell function and tumor immune surveillance. The natural cytotoxicity receptor-3 (NCR3) gene is transcribed into several splice variants whose physiological relevance is still incompletely understood. In this study, we investigated the role of NKp30 and its major ligand B7 homolog 6 (B7-H6) in patients with hepatocellular carcinoma (HCC). Peripheral blood NK cell phenotype was skewed toward a defective/exhausted immune profile with decreased frequencies of cells expressing NKp30 and natural killer group 2, member D and an increased proportion of cells expressing T-cell immunoglobulin and mucin-domain containing-3. Moreover, NKp30-positive NK cells had a reduced expression of NCR3 immunostimulatory splice variants and an increased expression of the inhibitory variant in patients with advanced tumor, resulting in deficient NKp30-mediated functionality. Tumor-infiltrating lymphocytes showed a prevalent inhibitory NKp30 isoform profile, consistent with decreased NKp30-mediated function. Of note, there were significant differences in the cytokine milieu between the neoplastic and the surrounding non-neoplastic tissue, which may have further influenced NKp30 function. Exposure of NK cells to B7-H6-expressing HCC cells significantly down-modulated NKp30, that was prevented by small interfering RNA-mediated knockdown, suggesting a role for this ligand in inhibiting NKp30-mediated responses. Interestingly, B7-H6 expression was reduced in HCC tissue and simultaneously augmented as a soluble form in HCC patients, particularly those with advanced staging or larger nodule size. Conclusion: These findings provide evidence in support of a role of NKp30 and its major ligand in HCC development and evolution.

Kidney donation after circulatory death (DCD) is a less than ideal option to meet organ shortages. Hypothermic machine perfusion (HMP) with Belzer solution (BS) improves the viability of DCD kidneys, although the graft clinical course remains critical. Mesenchymal stromal cells (MSC) promote tissue repair by releasing extracellular vesicles (EV). We evaluated whether delivering MSC-/MSC-derived EV during HMP protects rat DCD kidneys from ischaemic injury and investigated the underlying pathogenic mechanisms. Warm ischaemic isolated kidneys were cold-perfused (4 hrs) with BS, BS supplemented with MSC or EV. Renal damage was evaluated by histology and renal gene expression by microarray analysis, RT-PCR. Malondialdehyde, lactate, LDH, glucose and pyruvate were measured in the effluent fluid. MSC-/EV-treated kidneys showed significantly less global ischaemic damage. In the MSC/EV groups, there was up-regulation of three genes encoding enzymes known to improve cell energy metabolism and three genes encoding proteins involved in ion membrane transport. In the effluent fluid, lactate, LDH, MDA and glucose were significantly lower and pyruvate higher in MSC/EV kidneys as compared with BS, suggesting the larger use of energy substrates by MSC/EV kidneys. The addition of MSC/EV to BS during HMP protects the kidney from ischaemic injury by preserving the enzymatic machinery essential for cell viability and protects the kidney from reperfusion damage.

Desmoid tumours are benign, myofibroblastic stromal neoplasms common in Gardner's syndrome, which is a subtype of familial adenomatous polyposis characterized by colonic polyps, osteomas, thyroid cancer, epidermoid cysts, fibromas and sebaceous cysts. The primary treatment is surgery, followed by adjuvant radiotherapy, but the local recurrence rate is high, and wide resection can result in debilitating loss of function. We report the case of a 39-year-old man with Gardner's syndrome who had already undergone a total prophylactic colectomy. He developed desmoid tumours localized in the mesenteric root, abdominal wall and dorsal region, which were treated from 2003 through 2013 with several surgical procedures and percutaneous radiofrequency ablation. In 2008 and 2013, RFA was applied under ultrasonographic guidance to two desmoid tumours localized in the dorsal thoracic wall. The outcomes were low-grade pain and one case of superficial skin necrosis, but so far there has been no recurrence of desmoid tumours in these locations. Surgical resection remains the first-line therapy for patients with desmoid tumours, but wide resection may lead to a poor quality of life. Radiofrequency ablation is less invasive and expensive and is a possible therapeutic option for desmoid tumours in patients with Gardner's syndrome.

BACKGROUND AND STUDY AIM: The development of a new cholangioscope, the SpyGlass™ Discover (Boston Scientific), has allowed the laparoscopic transcystic common bile duct exploration and stone clearance. The possibility of simultaneous treatment of choledocholithiasis during early laparoscopic cholecystectomy offers the opportunity to enormously reduce the time between acute cholecystitis diagnosis and the execution of cholecystectomy with better outcomes for patients. Furthermore, an altered anatomy of the gastrointestinal tract is not an obstacle to this technique. The aim of the study was to determine whether this new procedure is feasible, safe, and effective. PATIENTS AND METHODS: The investigation employs a retrospective case series study including all consecutive patients with a diagnosis of common bile duct stones undergoing cholecystectomy and intraoperative laparoscopic common bile duct clearance using SpyGlass™ Discover at IRCCS Policlinico San Matteo in Pavia (Italy). Eighteen patients were included from May 2022 to May 2023. RESULTS: A complete clearance of the common bile duct was obtained in 88.9% of patients. The mean postoperative length of stay was 3 days. No major complications occurred. After a median follow-up of 8 months, no recurrence of biliary events or readmissions occurred. CONCLUSION: This procedure has proven to be feasible, safe, and effective.

BACKGROUND: The aim of this national survey on liver hypertrophy techniques was to track the trends of their use and implementation in Italy and to detect analogies and heterogeneities among centers. METHODS: In December 2022, Italian centers with liver resection activity were specifically contacted and asked to fill an online questionnaire composed of 6 sections including a total of 51 questions. RESULTS: 46 Italian centers filled the questionnaire. The proportion of major/total number of liver resections was 27% and the use of hypertrophy techniques was required in 6,2% of cases. The most frequent reason of drop out was disease progression in 58.5% of cases. Most frequently used techniques were PVE and ALPPS with an increasing use of hepatic venous deprivation (HVD). Heterogeneous answers were provided regarding the cutoff values to indicate the need for hypertrophy techniques. Criteria to allocate a patient to different hypertrophy techniques are not standardized. CONCLUSIONS: The use of hypertrophy techniques is deep-rooted in Italy, documenting the established value of their role in improving resectability rate. While an evolution of techniques is detectable, still significant heterogeneity is perceived in terms of cutoff values, indications and managing protocols.
RESUMO
Liver resection is the mainstay of treatment for patients with primary and metastatic liver tumors. However, a large majority of patients present for initial medical evaluation with primary and metastatic liver tumors when their cancer is unresectable. Several trials have been undertaken to identify alternative treatments and complementary therapies. In the near future, the field of liver surgery will aim to increase the number of patients that can benefit from resection, since radical removal of the tumor currently provides the sole chance of cure. This paper reports the case of a patient with an advanced colonic cancer in the era of stem cell therapy. In 2011, a 57 years old white Caucasian man with a previous history of non-Hodgkin lymphoma (NHL) was diagnosed with colon cancer and bilobar liver metastases. Following neoadjuvant therapy, the patient was enrolled in a protocol of stem cell administration for liver regeneration. Surgery was initially performed on the primary cancer and left liver lobe. An extended right lobectomy to S1 was then performed after a portal vein embolization (PVE) and stem cell stimulation of the remaining liver. The postoperative course was uneventful and the patient was free of disease after 12 months. Extreme liver resection can provide a safer option and a chance of cure to otherwise unresectable patients when liver regeneration is boosted by PVE and stem cell administration.

OBJECTIVES: Surgical excision is the standard strategy for managing liver metastases from colorectal carcinoma. The achievement of negative (R0) margins is a major determinant of disease-free survival in these patients. Current imaging techniques are of limited value in achieving this goal. A new approach to the intraoperative detection of colorectal liver metastatic tissue based on the emission of indocyanine green (ICG) fluorescence was evaluated. METHODS: A total of 25 consecutive patients with liver metastases from primary colorectal cancers who were eligible for liver resection received a bolus of ICG (0.5 mg/kg body weight) 24 h before surgery. During surgery, ICG fluorescence, which accumulates around lesions as a result of defective biliary clearance, was detected with a near-infrared camera system, the Photodynamic Eye (PDE). Numbers of lesions detected by, respectively, PDE + ICG, intraoperative ultrasound (IOUS) and preoperative computed tomography (CT) were recorded. RESULTS: The near-infrared camera plus ICG revealed a total of 77 metastatic liver nodules. Preoperative CT demonstrated 45 (58.4%) and IOUS showed 55 (71.4%). Preoperative CT and IOUS alone were inferior to the combined use of PDE + ICG and IOUS in the detection of lesions of ≤ 3 mm in size. CONCLUSIONS: This experience suggests that PDE + ICG, combined with IOUS, may represent a safe and effective tool for ensuring the complete surgical eradication of liver metastases from colorectal cancer.

Key Clinical Message: Concurrent polycystic liver disease and echinococcus infection can hinder diagnosis. Surgery may be needed for accurate diagnosis and treatment. Multidisciplinary collaboration is crucial. Abstract: Cystic echinococcosis, caused by Echinococcus granulosus eggs, is a parasitic zoonosis that typically affects humans through accidental ingestion. Polycystic liver disease is a condition characterized by the presence of multiple liver cysts and is often associated with polycystic kidney disease. Here, we present a case of a man in his 70s with a pre-existing diagnosis of polycystic liver disease. Radiological findings of a suspicious cyst in the S4 segment initially lacked serological evidence of echinococcosis; however, intraoperative confirmation revealed the presence of an echinococcal cyst. This article aims to explore both clinical conditions and highlight the therapeutic considerations for their management. Moreover, we discuss the significance of this unique case, emphasizing the possibility of the coexistence of these two pathologies.
RESUMO
International guidelines exclude from surgery patients with peritoneal carcinosis of colorectal origin and a peritoneal cancer index (PCI) ≥ 16. This study aims to analyze the outcomes of patients with colorectal peritoneal carcinosis and PCI greater or equal to 16 treated with cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) (CRS + HIPEC). We retrospectively performed a multicenter observational study involving three Italian institutions, namely the IRCCS Policlinico San Matteo in Pavia, the M. Bufalini Hospital in Cesena, and the ASST Papa Giovanni XXIII Hospital in Bergamo. The study included all patients undergoing CRS + HIPEC for peritoneal carcinosis from colorectal origin from November 2011 to June 2022. The study included 71 patients: 56 with PCI < 16 and 15 with PCI ≥ 16. Patients with higher PCI had longer operative times and a statistically significant higher rate of not complete cytoreduction, with a Completeness of Cytoreduction score (CC) 1 (microscopical disease) of 30.8% (p = 0.004). The 2-year OS was 81% for PCI < 16 and 37% for PCI ≥ 16 (p < 0.001). The 2-years DFS was 29% for PCI < 16 and 0% for PCI ≥ 16 (p < 0.001). The 2-year peritoneal DFS for patients with PCI < 16 was 48%, and for patients with PCI ≥ 16 was 57% (p = 0.783). CRS and HIPEC provide reasonable local disease control for patients with carcinosis of colorectal origin and PCI ≥ 16. Such results form the basis for new studies to reassess the exclusion of these patients, as set out in the current guidelines, from CRS and HIPEC. This therapy, combined with new therapeutical strategies, i.e., pressurized intraperitoneal aerosol chemotherapy (PIPAC), could offer reasonable local control of the disease, preventing local complications. As a result, it increases the patient's chances of receiving chemotherapy to improve the systemic control of the disease.
RESUMO
BACKGROUND: Hepatocellular carcinoma (HCC) is a leading cause of cancer-related death. Abdominal ultrasound (US) is by far the most widely used first-level exam for the diagnosis of HCC. We aimed to assess whether different ultrasound patterns were related to tumor prognosis. METHODS: We retrospectively reviewed all patients with a new diagnosis of HCC (single nodule) and undergoing radiofrequency thermal ablation (RFTA) at our clinic between January 2009 and December 2021. Patients were classified according to four HCC ultrasound patterns: 1A, single capsulated nodule; 1B, well capsulated intra-node nodule; 1C, cluster consisting of capsulated nodules; and 2, non-capsulated nodule. RESULTS: 149 patients were analysed; median follow-up time was 43 months. US patterns 1A (32.9%) and 1B (61.1%) were the most commonly seen. Median overall survival (OS) and recurrence-free survival (RFS) from RFTA were 54 months (95% CI, 42-66) and 22 months (95% CI, 12-32), respectively. Pattern 1A showed the best OS. Compared to pattern 1A, 1B was independently associated with worse OS (51 months (95% CI, 34-68) vs. 46 months (95% CI, 18-62)) and RFS (34 months (95% CI, 27-41) vs. 18 months (95% CI, 12-24)). Patterns 1C and 2 were associated with worse RFS compared to 1A, while no difference was seen for OS. Among baseline clinical variables, pattern 1B exhibited higher histological grade (p = 0.048) and tumor dimension (p = 0.034) compared to pattern 1A. CONCLUSIONS: Our findings demonstrate that different US patterns correlate with different survival outcomes and tumor behavior in patients with HCC. Prospective studies are needed to confirm these results.
