Alpelisib for PIK3CA-mutated advanced gynecological cancers: First clues of clinical activity.

OBJECTIVE: Recurrent gynecological tumors (e.g., endometrial, and ovarian cancers) are incurable diseases; therefore, new treatment options are urgently needed. The PTEN-AKT-PI3K pathway is frequently altered in these tumors, representing a potential treatment target. Alpelisib is an α-specific PI3K inhibitor approved in PIK3CA-mutated advanced breast cancer. We report outcomes from a large series of patients with PIK3CA-mutated gynecological cancers prospectively treated with alpelisib within a controlled program. METHODS: From April 2021 to December 2022, 36 patients with PIK3CA-mutated advanced gynecological cancers received alpelisib 300 mg orally once daily. Objective response (ORR) and disease control (DCR) rates provided measure of the antitumor activity of alpelisib, the primary objective of the study. RESULTS: Included patients had endometrial (17/36 [47%]), ovarian (10/36 [28%]), or other gynecological cancers (9/36 [25%]). Most patients had received 2-3 prior systemic treatments (endometrial, 47·2%; ovarian, 60%; other, 56%), and presented with visceral metastases at baseline (82%, 70%, and 56%, respectively). Overall, 17 different PIK3CA mutations were found, including 53% in the kinase domain (most commonly H1047R) and 36% in the helical domain (most commonly E545K). Overall, the ORR was 28% and DCR was 61%, with the greatest benefit observed in patients with endometrial cancer (35% and 71%, respectively). CONCLUSION: Alpelisib represents an active treatment option in patients with recurrent gynecological cancers harboring a PIK3CA mutation. These findings support the need of biomarker-driven randomized trials of PI3K inhibitors in gynecological cancers.

Reirradiation with radiosurgery or stereotactic fractionated radiotherapy in association with regorafenib in recurrent glioblastoma.

PURPOSE: No standard treatment has yet been established for recurrent glioblastoma (GBM). In this context, the aim of the current study was to evaluate safety and efficacy of reirradiation (re-RT) by radiosurgery or fractionated stereotactic radiotherapy (SRS/FSRT) in association with regorafenib. METHODS: Patients with a histological or radiological diagnosis of recurrent GBM who received re-RT by SRS/FSRT and regorafenib as second-line systemic therapy were included in the analysis. RESULTS: From January 2020 to December 2022, 21 patients were evaluated. The median time between primary/adjuvant RT and disease recurrence was 8 months (range 5-20). Median re-RT dose was 24 Gy (range 18-36 Gy) for a median number of 5 fractions (range 1-6). Median regorafenib treatment duration was 12 weeks (range 3-26). Re-RT was administered before starting regorafenib or in the week off regorafenib during the course of chemotherapy. The median and the 6­month overall survival (OS) from recurrence were 8.4 months (95% confidence interval [CI] 6.9-12.7 months) and 75% (95% CI 50.9-89.1%), respectively. The median progression-free survival (PFS) from recurrence was 6 months (95% CI 3.7-8.5 months). The most frequent side effects were asthenia that occurred in 10 patients (8 cases of grade 2 and 2 cases of grade 3), and hand-foot skin reaction (2 patients grade 3, 3 patients grade 2). Adverse events led to permanent regorafenib discontinuation in 2 cases, while in 5/21 cases (23.8%), a dose reduction was administered. One patient experienced dehiscence of the surgical wound after reintervention and during regorafenib treatment, while another patient reported intestinal perforation that required hospitalization. CONCLUSION: For recurrent GBM, re-RT with SRT/FSRT plus regorafenib is a safe treatment. Prospective trials are necessary.

The Role of Laparoscopic Surgery in Localized Pancreatic Neuroendocrine Tumours.

OPINION STATEMENT: Pancreatic neuroendocrine tumours (PNETs) are a rare and heterogeneous group of tumours with various clinical manifestations and biological behaviours. They represent approximately 2-4% of all pancreatic tumours, with an incidence of 2-3 cases per million people. PNETs are classified clinically as non-functional or functional, and pancreatic resection is recommended for lesions greater than 2 cm. The surgical approach can involve "typical" and "atypical" resections depending on the number, size and location of the tumour. Typical resections include pancreaticoduodenectomy, distal pancreatectomy enucleation and, rarely, total pancreatectomy. Atypical resections comprise central pancreatectomies or enucleations. Minimally invasive pancreatic resection has been proven to be technically feasible and safe in high-volume and specialized centres with highly skilled laparoscopic surgeons, with consolidated benefits for patients in the postoperative course. However, open and minimally invasive pancreatic surgery remains to have a high rate of complications; there is no specific technical contraindication to minimally invasive pancreatic surgery, but an appropriate patient selection is crucial to obtain satisfactory clinical and oncological outcomes.

Targeted Therapies for Prostate Cancer.

New therapies for prostate cancer have emerged over the past three years. Nevertheless, none of these agents is curative, and unfortunately, patients often ultimately develop resistance to these agents. Therefore, the development of innovative and effective therapies that overcome these resistances is necessary. Unfortunately, the results of a phase III trial evaluating docetaxel in combination with targeted therapies demonstrated no difference in survival. Moreover, scarce data on the combination of a targeted therapy with new agents are currently available. New trials are investigating these possible combination treatments; the results of these (on-going) clinical studies are awaited.

Carboplatin, methotrexate, vinblastine, and epirubicin (M-VECa) as salvage treatment in patients with advanced bladder cancer: a phase II study.

The primary objective of this study was to determine the activity and safety of carboplatin, methotrexate, vinblastine, and epirubicin (the M-VECa regimen) in patients with advanced bladder cancer after failure of at least one chemotherapy line. Treatment consisted of carboplatin 250 mg/m on day 1, methotrexate 30 mg/m on days 1 and 22, vinblastine 3 mg/m on days 2 and 22, and epirubicin 50 mg/m on day 2 every 28 days until disease progression or death. Response rate was the main end-point. Twenty-five patients were enrolled: the median age was 67 years (range 42-83) and there were 14 patients aged at least 70 years (56%). Fourteen patients had previously received vinflunine as a second-line treatment. Complete remission occurred in one patient (4%), partial remission in five patients (20%), and stable disease in eight patients (32%). The overall response rate was 24% [95% confidence interval (CI), 9.3-45.1%] and the overall disease control rate was 56% (95% CI, 34.9-75.5%). The median progression-free survival was 5.1 months (95% CI, 3.9-6.4) and the median overall survival was 9.5 months (95% CI, 7.1-11.2). Treatment was well tolerated: grade 3 neutropenia was documented in five patients and grade 3 nausea and vomiting in two patients. The M-VECa regimen seems to be feasible as second-line or third-line treatment in patients with advanced bladder cancer who have been pretreated with one or more chemotherapy lines, and may achieve encouraging results in terms of disease control rate, progression-free survival, and overall survival.

Tolerability of cabazitaxel in patients with metastatic castration-resistant prostate cancer progressing after docetaxel and abiraterone acetate: a single-institution experience.

Both abiraterone acetate (AA) and cabazitaxel (Cbz) have been shown to prolong survival in patients with metastatic castration-resistant prostate cancer (mCRPC) progressing during or after docetaxel (D). Although no standard sequencing has been established as yet, Cbz has recently been proven to be active after AA. However, to date, few data are available on its safety in this setting. Therefore, the primary endpoint of this study was to investigate Cbz tolerability in mCRPC patients treated previously with D and AA. From April 2011 to the present, 43 mCRPC patients received AA after D at our institution. Of these, 22 patients were subsequently treated with Cbz and were evaluable for toxicity in the present retrospective study. Cbz was administered at a dose of 25 mg/m plus 10 mg oral prednisone every 3 weeks. Adverse events (AEs) were reported using the NCI CTCAE (National Cancer Institute Common Terminology Criteria for Adverse Events) version 3.0. Despite the advanced stage of disease and frailty of our study population, there were no unexpected side effects. The most common AEs were hematologic. Neutropenia was observed in nine (40.9%) patients and of grade≥3 in six (27.2%). No febrile neutropenia occurred. The most common nonhematologic AEs were diarrhea and asthenia, reported in eight (36.3%) and in five (22.7%) patients, respectively. In this setting, Cbz toxicity seems to be manageable and comparable with second-line Cbz. Therefore, our results seem to support the safety of Cbz as a third-line treatment for mCRPC patients.

Three-weekly oxaliplatin combined with gemcitabine and capecitabine in the first-line treatment of patients with advanced biliary tract cancer.

The primary objective of this study was to determine the activity and safety of 3-weekly oxaliplatin combined with gemcitabine and oral capecitabine in the first-line treatment of advanced biliary tract cancer. Treatment consisted of intravenous oxaliplatin 100 mg/m every 3 weeks combined with intravenous gemcitabine 1000 mg/m on days 1 and 8 and oral capecitabine 1500 mg/m 14 days on 21 in two divided doses. Treatment was administered until progressive disease, unacceptable toxicity, or patient refusal. Thirty-seven patients were enrolled: eight patients had Eastern Cooperative Oncology Group 2 performance status at presentation. The overall response rate was 35.1% [95% confidence interval (CI): 20.2-52.5%] and the disease control rate was 72.9%. The median progression-free survival was 9.4 months (95% CI: 4.1-12.2 months) and the median overall survival was 13.8 months (95% CI: 7.7-17.1 months). There were no grade 4 toxicities. Grade 3 neutropenia occurred in 13.5% of patients and grade 3 thrombocytopenia in 10.8%. The present study suggests that 3-weekly oxaliplatin combined with gemcitabine and oral capecitabine is an active and well-tolerated chemotherapy regimen in the first-line treatment of metastatic biliary tract cancer.

Maintenance treatment with oral cyclophosphamide and bevacizumab in patients with recurrent epithelial ovarian cancer.

AIM: To evaluate the efficacy and safety of maintenance treatment with oral cyclophosphamide (Cy) and bevacizumab (Bev) in patients with recurrent ovarian cancer. PATIENTS & METHODS: Induction treatment consisted of cisplatin, epirubicin, Cy and Bev every 3 weeks, for a maximum of six cycles. Maintenance treatment consisted of oral Cy 50 mg, days 1-14 and Bev 15 mg/kg, every 3 weeks until disease progression occurred. RESULTS: In total, 39 patients were enrolled: after induction chemotherapy, the objective response was 74.3%. The median progression-free survival was 13.3 months, and the median overall survival was 33.2 months. Toxicity during maintenance treatment was mild. CONCLUSION: Maintenance with Cy and Bev may achieve encouraging results in terms of progression-free survival and overall survival in recurrent ovarian cancer patients.

PSA response rate as a surrogate marker for median overall survival in docetaxel-based first-line treatments for patients with metastatic castration-resistant prostate cancer: an analysis of 22 trials.

The aim of this study was to determine the correlation between PSA response rate (PSA RR) and overall survival (OS) and identify PSA RR as a potential surrogate for OS, in docetaxel-based first-line treatments for castration-resistant prostate cancer (CRPC). Trials of first-line regimens with docetaxel for patients with metastatic CRCP published between 2004 and 2013 were identified, and data were evaluated statistically in order to investigate the correlation between PSA RR and OS. A total of 22 trials were identified and included in our analysis, for a total of 7,677 patients. In addition, we divided all the trails and arms of the randomized trials in two subgroups, the first one composed only of docetaxel (D) plus prednisone (P) regimens (standard therapy) and the second one composed of all D + other drug combinations (D combinations). Analysing all the trials and arms as a single unit, we found a statistically significant correlation between PSA RR and OS, with Spearman's rank correlation coefficient ρ = 0.50 (95% confidence interval (CI), 0.47 to 0.88) (P = 0.003). Also evaluating the standard therapy group, we found a statistically significant correlation between PSA RR and OS, with Spearman's ρ = 0.65 (95% CI, 0.38 to 0.70) (P = 0.02). However, when we assessed the D combination group, we found Spearman's rank correlation coefficient decreased (ρ = 0.42) (95% CI, 0.28 to 0.80) and resulted nonstatistically significant (P = 0.06). In conclusion, we found a statistically significant correlation between PSA RR and OS. The usage of PSA RR as a surrogate marker for OS in metastatic CRPC patients treated with D-based first-line regimens may be appropriate only in the D + P combination.

Abiraterone in heavily pretreated patients with metastatic castrate-resistant prostate cancer.

The aim of this study was to evaluate the activity and tolerability of abiraterone acetate in patients with metastatic castrate-resistant prostate cancer treated previously with more than three lines of chemotherapy. Patients received 1 g of abiraterone acetate (administered as four 250 mg tablets) orally once daily with prednisone at a dose of 5 mg orally twice daily. The primary endpoint was prostate-specific antigen (PSA) response. From August 2011 to January 2013, 36 patients were enrolled. PSA response was observed in 22 patients (61.1%, 95% confidence interval: 0.41-0.81). The median time to PSA progression was 7.3 months and after a median follow-up of 10.1 months, all patients were alive. The treatment was generally well tolerated; side effects secondary to mineralocorticoid excess resulting from blockade of CYP17 were largely controlled with prednisone. Abiraterone acetate seems to be an effective and well-tolerated treatment option for patients with metastatic castrate-resistant prostate cancer irrespective of the number of chemotherapy lines administered previously.

Case report: Germline POT1 mutation in a patient with GIST and lung adenocarcinoma.

The gene protection of telomere 1 (POT1) is involved in telomere maintenance and stability and plays a crucial role in the preservation of genomic stability. POT1 is considered a high-penetrance melanoma susceptibility gene; however, the number of cancer types associated with the pathogenic germline variants of POT1 is gradually increasing, including chronic lymphocytic leukemia (CLL), angiosarcomas, and gliomas, even though many associations are still elusive. Here, we reported a case of a 60-year-old man who showed early-onset multiple neoplasms, including multiple melanomas, gastrointestinal stromal tumor (GIST), and lung adenocarcinoma. Next-generation sequencing (NGS) analyses revealed a germline heterozygous pathogenic variant in the POT1 gene. Notably, GIST and lung adenocarcinoma were not previously reported in association with the POT1 germline variant. Lung cancer susceptibility syndrome is very rare and the actual knowledge is limited to a few genes although major genetic factors are unidentified. Recently, genome-wide association studies (GWAS) have pointed out an association between POT1 variants and lung cancer. This case report highlights the clinical relevance of POT1 alterations, particularly their potential involvement in lung cancer. It also suggests that POT1 testing may be warranted in patients with familial cancer syndrome, particularly those with a history of melanoma and other solid tumors.

Impact of influenza vaccination on survival of patients with advanced cancer receiving immune checkpoint inhibitors (INVIDIa-2): final results of the multicentre, prospective, observational study.

Background: The prospective multicentre observational INVIDIa-2 study investigated the clinical effectiveness of influenza vaccination in patients with advanced cancer receiving immune checkpoint inhibitors (ICI). In this secondary analysis of the original trial, we aimed to assess the outcomes of patients to immunotherapy based on vaccine administration. Methods: The original study enrolled patients with advanced solid tumours receiving ICI at 82 Italian Oncology Units from Oct 1, 2019, to Jan 31, 2020. The trial's primary endpoint was the time-adjusted incidence of influenza-like illness (ILI) until April 30, 2020, the results of which were reported previously. Secondary endpoints (data cut-off Jan 31, 2022) included the outcomes of patients to immunotherapy based on vaccine administration, for which the final results are reported herein. A propensity score matching by age, sex, performance status, primary tumour site, comorbidities, and smoking habits was planned for the present analysis. Only patients with available data for these variables were included. The outcomes of interest were overall survival (OS), progression-free survival (PFS), objective response rate (ORR), and disease-control rate (DCR). Findings: The original study population consisted of 1188 evaluable patients. After a propensity score matching, 1004 patients were considered (502 vaccinated and 502 unvaccinated), and 986 of them were evaluable for overall survival (OS). At the median follow-up of 20 months, the influenza vaccination demonstrated a favourable impact on the outcome receiving ICI in terms of median OS [27.0 months (CI 19.5-34.6) in vaccinated vs. 20.9 months (16.6-25.2) in unvaccinated, p = 0.003], median progression-free survival [12.5 months (CI 10.4-14.6) vs. 9.6 months (CI 7.9-11.4), p = 0.049], and disease-control rate (74.7% vs. 66.5%, p = 0.005). The multivariable analyses confirmed the favourable impact of influenza vaccination in terms of OS (HR 0.75, 95% C.I. 0.62-0.92; p = 0.005) and DCR (OR 1.47, 95% C.I. 1.11-1.96; p = 0.007). Interpretation: The INVIDIa-2 study results suggest a favourable immunological impact of influenza vaccination on the outcome of cancer patients receiving ICI immunotherapy, further encouraging the vaccine recommendation in this population and supporting translational investigations about the possible synergy between antiviral and antitumour immunity.

Radiosurgery and Stereotactic Brain Radiotherapy with Systemic Therapy in Recurrent High-Grade Gliomas: Is It Feasible? Therapeutic Strategies in Recurrent High-Grade Gliomas.

PURPOSE: For recurrent high-grade gliomas (HGG), no standard therapeutic approach has been reported; thus, surgery, chemotherapy, and re-irradiation (re-RT) may all be proposed. The aim of the study was to evaluate safety and efficacy of re-RT by radiosurgery or fractionated stereotactic radiotherapy (SRS/FSRT) in association to chemotherapy in patients with recurrent HGG. MATERIAL/METHODS: All patients with histological diagnosis of HGG that suffered by recurrent disease diagnosed by magnetic resonance imaging (MRI), according to Response Assessment in Neuro-Oncology (RANO) criteria, after primary/adjuvant chemo-radiotherapy treatment and underwent to re-RT by SRS/FSRT were included in the analysis. Second-line chemotherapy was administered. Outcomes were evaluated by neurological examination and brain MRI performed 1 month after re-RT and then every 2-3 months. RESULTS: From November 2019 to September 2021, 30 patients presenting recurrent HGG underwent re-RT. Median dose was 24 Gy (range 15-36 Gy), and median fractions was 5 (range 1-6). Twenty-one patients (70%) had RPA class ≤ IV. One patient had a histological diagnosis of anaplastic oligodendroglioma, 24 patients (80%) were affected by glioblastoma (GBM) including 3 cases of multifocal form, and 5 patients (17%) by anaplastic astrocytoma. Median time between primary/adjuvant RT and disease recurrence was 8 months. In six cases (20%) re-operation was performed, and in most cases (87%), a second line of systemic therapy was administrated. At a median follow-up time from recurrence of 13 months (range 6-56 months), 10 patients (33%) were alive: 2 patients with partial response disease, 7 patients with stable disease, and 1 patient with out-field progression disease. Of the 20 patients who died (67%), 15 (75%) died for progression disease and 5 (25%) for other causes (3 due to septic event, 1 due to thrombo-embolic event, and 1 due to car accident). Median OS and PFS after recurrence were 12.1 and 11.2 months. Six-month and one-year OS were, respectively, 81% and 51%. No acute or late neurological side effects grade ≥ 2 and no case of radio-necrosis were reported. One patient experienced, after reintervention and during Regorafenib treatment (administered 40 days after surgery), dehiscence of the surgical wound. In three cases, grade 2 distal paresthesia was reported. Grade 3-4 hematologic toxicity occurred in seven cases. Three case of grade 5 toxicities during chemotherapy were reported: three septic events and one thrombo-embolic event. CONCLUSION: Re-RT with SRT/FSRT in association with second-line systemic therapy is a safe and feasible treatment for patients with HGG recurrence. Validation of these results by prospective studies is needed.

Worldwide management of hepatocellular carcinoma during the COVID-19 pandemic.

The coronavirus disease 2019 (COVID-19) pandemic has impacted hospital organization, with the necessity to quickly react to face the pandemic. The management of the oncological patient has been modified by necessity due to different allocation of nurses and doctors, requiring new strategies to guarantee the correct assistance to the patients. Hepatocellular carcinoma, considered as one of the most aggressive types of liver cancer, has also required a different management during this period in order to optimize the management of patients at risk for and with this cancer. The aim of this document is to review recommendations on hepatocellular carcinoma surveillance and management, including surgery, liver transplantation, interventional radiology, oncology, and radiotherapy. Publications and guidelines from the main scientific societies worldwide regarding the management of hepatocellular carcinoma during the COVID-19 pandemic were reviewed.

Current trends and perspectives in interventional radiology for gastrointestinal cancers.

Gastrointestinal (GI) cancers often require a multidisciplinary approach involving surgeons, endoscopists, oncologists, and interventional radiologists to diagnose and treat primitive cancers, metastases, and related complications. In this context, interventional radiology (IR) represents a useful minimally-invasive tool allowing to reach lesions that are not easily approachable with other techniques. In the last years, through the development of new devices, IR has become increasingly relevant in the context of a more comprehensive management of the oncologic patient. Arterial embolization, ablative techniques, and gene therapy represent useful and innovative IR tools in GI cancer treatment. Moreover, IR can be useful for the management of GI cancer-related complications, such as bleeding, abscesses, GI obstructions, and neurological pain. The aim of this study is to show the principal IR techniques for the diagnosis and treatment of GI cancers and related complications, as well as to describe the future perspectives of IR in this oncologic field.

Current status of non-surgical treatment of locally advanced pancreatic cancer.

Pancreatic cancer is the 7th leading cause of death due to cancer in industrialized countries and the 11th most common cancer globally, with 458918 new cases (2.5% of all cancers) and 432242 deaths (4.5% of all cancer deaths) in 2018. Unfortunately, 80% to 90% of the patients present with unresectable disease, and the reported 5-year survival rate range between 10% and 25%, even after successful resection with tumor-free margins. Systemic chemotherapy, radiotherapy, and minimally invasive image-guided procedures that have emerged over the past years, are used for the management of non-operable PC. This review focuses on currently available non-surgical options of locally advanced pancreatic cancer.

Non-surgical treatment of hilar cholangiocarcinoma.

Cancer of the biliary confluence also known as hilar cholangiocarcinoma (HC) or Klatskin tumor, is a rare type of neoplastic disease constituting approximately 40%-60% of intrahepatic malignancies, and 2% of all cancers. The prognosis is extremely poor and the majority of Klatskin tumors are deemed unresectable upon diagnosis. Most patients with unresectable bile duct cancer die within the first year after diagnosis, due to hepatic failure, and/or infectious complications secondary to biliary obstruction. Curative treatments include surgical resection and liver transplantation in highly selected patients. Nevertheless, very few patients are eligible for surgery or transplant at the time of diagnosis. For patients with unresectable HC, radiotherapy, chemotherapy, photodynamic therapy, and liver-directed minimally invasive procedures such as percutaneous image-guided ablation and intra-arterial chemoembolization are recommended treatment options. This review focuses on currently available treatment options for unresectable HC and discusses future perspectives that could optimize outcomes.

Poor-Prognosis Patients Affected by Glioblastoma: Retrospective Study of Hypofractionated Radiotherapy with Simultaneous Integrated Boost and Concurrent/Adjuvant Temozolomide.

BACKGROUND: Glioblastoma (GBM) is a very poor-prognosis brain tumor. To date, maximal excision followed by radiochemotherapy, in 30 fractions, is the standard approach. Limited data are present in the literature about hypofractionated radiotherapy (hypo-RT) in GBM poor prognosis patients. Thus, this retrospective study was conducted to evaluate efficacy and toxicity of hypo-RT with simultaneous integrated boost (SIB) in association with temozolomide (TMZ) in this patient setting. METHODS: Poor-prognosis GBM patients underwent surgery (complete, subtotal or biopsy) followed by SIB-hypo-RT and concomitant/adjuvant TMZ. The prescription dose was 40.05 Gy (15 fractions) with a SIB of 52.5 Gy (3.5 Gy/fraction) on surgical cavity/residual/macroscopic disease. Volumetric modulated arc therapy was performed. RESULTS: From July 2019 to July 2021, 30 poor-prognosis patients affected by GBM were treated by SIB-hypo-RT; 25 were evaluated in the present analysis due to a minimum follow up of 6 months. The median age and KPS were 65 years and 60%, respectively. At the median follow-up time of 15 months (range 7-24), median and 1-year overall survival and progression-free survival were 13 months and 54%, and 8.4 months and 23%, respectively. No acute or late neurological side effects of grade ≥ 2 were reported. Grade 3-4 hematologic toxicity occurred in three cases. CONCLUSION: SIB-hypo-RT associated with TMZ in poor-prognosis patients affected by GBM is an effective and safe treatment. Prospective studies could be warranted.

Radiofrequency ablation vs surgical resection in elderly patients with hepatocellular carcinoma in Milan criteria.

BACKGROUND: Surgical resection and radiofrequency ablation (RFA) represent two possible strategy in treatment of hepatocellular carcinoma (HCC) in Milan criteria. AIM: To evaluate short- and long-term outcome in elderly patients (> 70 years) with HCC in Milan criteria, which underwent liver resection (LR) or RFA. METHODS: The study included 594 patients with HCC in Milan criteria (429 in LR group and 165 in RFA group) managed in 10 European centers. Statistical analysis was performed using the Kaplan-Meier method before and after propensity score matching (PSM) and Cox regression. RESULTS: After PSM, we compared 136 patients in the LR group with 136 patients in the RFA group. Overall survival at 1, 3, and 5 years was 91%, 80%, and 76% in the LR group and 97%, 67%, and 41% in the RFA group respectively (P = 0.001). Disease-free survival at 1, 3, and 5 years was 84%, 60% and 44% for the LR group, and 63%, 36%, and 25% for the RFA group (P = 0.001).Postoperative Clavien-Dindo III-IV complications were lower in the RFA group (1% vs 11%, P = 0.001) in association with a shorter length of stay (2 d vs 7 d, P = 0.001).In multivariate analysis, Model for End-stage Liver Disease (MELD) score (> 10) [odds ratio (OR) = 1.89], increased value of international normalized ratio (> 1.3) (OR = 1.60), treatment with radiofrequency (OR = 1.46) ,and multiple nodules (OR = 1.19) were independent predictors of a poor overall survival while a high MELD score (> 10) (OR = 1.51) and radiofrequency (OR = 1.37) were independent factors associated with a higher recurrence rate. CONCLUSION: Despite a longer length of stay and a higher rate of severe postoperative complications, surgery provided better results in long-term oncological outcomes as compared to ablation in elderly patients (> 70 years) with HCC in Milan criteria.
