Abstract OBJECTIVES We retrospectively investigated oncological outcomes after video-assisted thoracoscopic surgery (VATS) lobectomy with lobe-specific mediastinal lymph node dissection (MLND). METHODS Between April 2008 and December 2016, a total of 660 patients underwent VATS lobectomy with lobe-specific MLND for clinical T1-3N0M0 non-small-cell lung cancer, of which 54 (8.2%) patients had pathological node-positive disease (18 N1 and 36 N2). We evaluated their oncological outcomes. RESULTS The predominant histological type was adenocarcinoma (87%). Six (33%) patients in the pN1 and 11 (31%) patients in the pN2 received adjuvant chemotherapy. The median follow-up period was 51.6 months. Postoperative recurrence was observed in 5 (28%) pN1 and 22 (61%) pN2 patients. One (6%) pN1 and 12 (33%) pN2 patients experienced locoregional recurrence. None of the pN1 patient experienced local recurrence at the dissected zone, whereas 11 (31%) pN2 patients had lymph node recurrence, including four at the dissected area and three in the area omitted from dissection in the lobe-specific MLND. The 5-year overall survival rates were 88.1% in the pN1 patients and 80.0% in the pN2 patients; the 5-year recurrence-free survival rates were 63.9% in the pN1 patients and 34.8% in the pN2 patients. In pN2 patients, pathological T classification was a prognostic factor for overall survival (P < 0.001) and recurrence-free survival (P = 0.034), and single-station N2 disease was also prognostic factor for overall survival (P = 0.023). CONCLUSIONS Recurrence at the omitted zone is an issue for this type of MLND. For pN1 patients, adequate MLND is an important factor for curative treatment. However, for pN2 patients, systemic treatment after recurrence may also contribute to survival.

Abstract PurposeTo investigate the survival difference between limited axillary surgery and full axillary lymph node dissection (ALND) in patients with 1-3 positive sentinel lymph node biopsies (SLNBs) after neoadjuvant chemotherapy (NAC).MethodWe retrospectively analyzed data from 676 patients who underwent surgery between 2007 and 2017 with cT1-4, cN0-3, cM0 breast cancer at the time of diagnosis and 1-3 positive SLNBs after NAC. The patients received either SLNB only or completed level I or II ALND based on SLNB results. After propensity score matching, 483 patients who had undergone SLNB only (n=188) and ALND (n=295) were included. We examined overall survival, axillary recurrence-free survival, regional recurrence-free survival, and distant metastasis-free survival and compared them between the subgroups.ResultAt a median follow-up of 59.4 months, no significant statistical difference was observed in overall survival, axillary recurrence-free survival, regional recurrence-free survival, and distant metastasis-free survival between SLNB only and ALND. No significant differences were observed in the 5-year axillary recurrence-free survival (93.1% vs. 94.0%, hazard ratio [HR]=0.94, 95% confidence interval [CI]=0.43-2.05, p=0.876) and 5-year overall survival (97.7% vs. 97.3%, HR=1.65, 95% CI=0.58-4.65, p=0.347) between the two groups.ConclusionOur analysis suggests that SLNB alone may be a possible option for patients with 1-3 sentinel node-positive breast cancer following NAC without significant compromise of recurrence or overall survival.

Introduction Although it has now been accepted that imatinib is a valid treatment for gastrointestinal stromal tumour (GIST) patients in the adjuvant setting, information on its clinical efficacy in improving the prognosis for patients with colorectal GISTs is limited. Methods The clinical and follow-up records of 42 colorectal GIST patients who underwent surgical resection at our institution between January 2004 and December 2013 were reviewed retrospectively. The effect of postoperative imatinib treatment on recurrence free survival and overall survival time was analysed with the Kaplan–Meier method and the multivariate Cox proportional hazards model. Results Sixteen patients were assigned to imatinib treatment (imatinib group) after surgical tumour resection while twenty-six patients did not receive any adjuvant treatment (control group). The one, three and five-year recurrence free survival rates were 100%, 90% and 77% respectively. This was significantly higher than in the control group (92%, 53% and 36%) (logrank test, p=0.012). The one, three and five-year overall survival rates were 100%, 91% and 68% in the imatinib group compared with 96%, 77% and 39% in the control group (logrank test, p=0.021). Analysis with the multivariate Cox regression model yielded similar results on the efficacy of adjuvant imatinib in prolonging both recurrence free survival (hazard ratio [HR]: 0.23, 95% confidence interval [CI]: 0.07–0.80) and overall survival (HR: 0.20, 95% CI: 0.05–0.91). Conclusions Adjuvant imatinib therapy seems to be effective in decreasing the risk of tumour occurrence and prolonging the overall survival time in colorectal GIST patients.

ObjectivePrognostic factors for endocervical adernocarcinomas are well known, but little is known about prognostic biomarkers influencing outcome for the newly defined International Federation of Gynecology and Obstetrics (FIGO) 2018 IB sub-stages. The aim of this study was to identify prognostic biomarkers influencing recurrence-free and overall survival for FIGO 2018 stage IB cervical adenocarcinoma sub-types. We sought to identify these factors using a large international multi-institutional series of cases.MethodsStage IB endocervical adenocarcinomas were retrospectively collected from nine international institutions; full slide sets (n=464) were used to assign prognostic biomarkers. Inclusion criteria were the following: FIGO stage IB endocervical adenocarcinomas with follow-up in which all paraffin blocks/glass slides were available for review and/or additional studies and the patient was surgically treated from 1985 to 2019. The types of specimens included in the study were conizations, trachelectomies, and simple/radical hysterectomies with or without lymph node samples. We excluded in situ carcinomas, squamous cell carcinomas, adenosquamous carcinomas, tumors with a neuroendocrine component, carcinosarcomas, and any tumor showing clinical, macroscopic, or microscopic features suggesting a lower uterine segment, uterine corpus, or an adnexal primary origin. Tumors treated with neoadjuvant chemotherapy and/or radiation therapy were also excluded, as well as biopsies and loop electrosurgical excision procedures.ResultsOf 464 cases, 225 (48%) were stage IB1, 177 (38%) were stage IB2, and 62 (13%) were stage IB3. Five-year and 10-year recurrence-free survivals were statistically different among stage IB sub-types (p=0.005). Silva pattern of invasion was significant for recurrence-free survival at 5 and 10 years (p=0.04); overall survival and recurrence-free survival were higher in human papillomavirus (HPV)-associated cases (p=0.007 and p=0.001, respectively) and in cases without lymphovascular invasion (p=0.004 and p=0.00001, respectively). Factors that significantly influenced recurrence-free survival were HPV-independent status (p=0.05; HR 2.31; 95% CI 1.02 to 5.46), presence of lymphovascular invasion (p=0.011; HR 3.50; 95% CI 1.33 to 9.19), and presence of lymph node metastasis (p=0.016; HR 2.66; 95% CI 1.20 to 5.90).ConclusionHPV status and the presence of lymphovascular invasion are prognosticators in stage IB endocervical adenocarcinoma sub-types. These parameters should be included in future sub-staging modifications of FIGO stage IB endocervical adenocarcinomas and in treatment strategies.

Abstract Background: The aim of this study was to evaluate whether combined therapy with PD-1 blockade (anti-PD-1) and radiofrequency ablation (RFA) was superior to RFA monotherapy for recurrent hepatocellular carcinoma (HCC).METHODS: A total of 127 patients who underwent anti-PD-1 plus RFA treatment (n = 41) or RFA alone treatment (n = 86) for recurrent HCC were enrolled in this retrospective study. Clinical data including post-RFA HCC recurrence (the primary end point), overall survival (OS) (the secondary end point), adverse events and toxic effects were retrospectively analyzed.RESULTS: The 1-year recurrence-free survival rates for the anti-PD-1 plus RFA and RFA groups were 36.6% and 16.3%, respectively. The corresponding overall survival rates for the two groups were 95.1% and 74.4%, respectively. There were statistically significant differences between the two groups in recurrence-free survival rate (P = 0.002) or overall survival rate (P = 0.008). Tumor number, TNM stage and anti-PD-1 treatment were demonstrated to be important factors associated with 1-year recurrence-free survival probability by univariate and multivariate analyses. Univariate and multivariate analyses demonstrated that tumor number, TNM stage and anti-PD-1 treatment were significant prognostic factors for OS. RFA treatment-related adverse events were pleural effusion requiring drainage and mild or moderate increase in body temperature. Grade 3 or higher events related to anti-PD-1 treatment occurred in 12.8% (6) patients and were infrequent.CONCLUSIONS: Combination therapy of anti-PD-1 plus RFA was superior to RFA alone in improving survival for recurrent HCC.

AbstractHepatic pedicle clamping reduces intraoperative blood loss and the need for transfusion, but its long-term effect on survival and recurrence remains controversial. The aim of this meta-analysis was to evaluate the effect of the Pringle maneuver (PM) on long-term oncological outcomes in patients with primary or metastatic liver malignancies who underwent liver resection. Literature was searched in the Cochrane Central Register of Controlled Trials (CENTRAL), Medline (via PubMed), and Web of Science databases. Survival was measured as the survival rate or as a continuous endpoint. Pooled estimates were represented as odds ratios (ORs) using the Mantel–Haenszel test with a random-effects model. The literature search retrieved 435 studies. One RCT and 18 NRS, including 7480 patients who underwent liver resection with the PM (4309 cases) or without the PM (3171 cases) were included. The PM did not decrease the 1-year overall survival rate (OR 0.86; 95% CI 0.67–1.09; P = 0.22) or the 3- and 5-year overall survival rates. The PM did not decrease the 1-year recurrence-free survival rate (OR 1.06; 95% CI 0.75–1.50; P = 0.75) or the 3- and 5-year recurrence-free survival rates. There is no evidence that the Pringle maneuver has a negative effect on recurrence-free or overall survival rates.

AbstractAim:Multiform glioblastoma (MG) represents 70% of all gliomas, with half of patients older than 65 years with median survival of 12–18 months, hypofractionation seeks to reduce the intensity and duration of treatment without impacting on survival rates. The objective was to determine the global survival and recurrence-free survival of adults over 70 years old with MG treated with hypofractionated radiotherapy and standard scheme. The review of patients older than 70 years treated with radiotherapy from 2013 to 2016 was performed.Results:Twenty-four patients were analysed, with a median follow-up of 239 days, and there is no difference in overall survival 12·3 versus 10·5 months (p = 0·55) and recurrence-free survival 8·3 versus 3·4 months (p = 0·48) between both schemes, conventional versus hypofractioanted, respectively.Conclusion:The results in this study show that hypofractionated scheme could be comparable in overall survival and recurrence-free survival to conventional fractionation, but a longer patients’ trial should be done.
