Abstract Introduction Role of biomarkers for promotion of tumor proliferation (BPTPs) and for promotion of apoptosis (BPAs) in thymic malignant tumors is still unclear. The purpose of this study was to evaluate the relationship between BPTPs and/or BPAs and malignancy of thymic malignant tumors. Materials and Methods Studies on thymic malignant tumors and biomarkers were searched in PubMed, ISI Web of Knowledge, and Embase databases, and all statistical analyses were conducted using Review Manager. Results Twelve articles related to biomarkers and thymic malignant tumors were selected and analyzed. A relationship between BPAs and Masaoka stage was demonstrated for four markers, included 138 stage I/II patients and 74 stage III/IV patients, and BPAs were significantly correlated with high Masaoka staging (P = 0.005). We further found a relationship between BPAs and degree of malignancy for four markers, included 176 thymoma patients and 36 thymic carcinoma patients, and BPAs were significantly correlated with thymic carcinoma (P = 0.010). In addition, a relationship between BPTP and Masaoka staging was demonstrated for eight markers, included 374 patients with stage I/II and 282 patients with stage III/IV, and BPTPs were significantly correlated with high Masaoka staging (P < 0.001). We also found BPTPs were significantly correlated with thymic carcinoma (P < 0.001). Conclusion These findings show that high levels of BPTPs or BPAs are more closely related to thymic carcinoma and Masaoka stage III/IV, suggesting that BPTPs and BPAs may play an important role in the occurrence and development of thymic malignant tumors.

Purpose Molecular biology-based ultrastaging of cancer is already part of the standard management of patients with hematologic malignancies, whereas the evidence for solid tumors is much more debated. Polymerase chain reaction (PCR) –based detection of melanoma cells in sentinel lymph nodes (SLN) of patients with melanoma represents an appealing prognostic tool. However, no consensus exists on the clinical implementation of this prognostic indicator for the management of these patients. Methods Twenty-two studies enrolling 4,019 patients who underwent SLN biopsy for clinical stage I to II cutaneous melanoma were reviewed. Correlation of PCR status with TNM stage, disease recurrence rates, and survival was assessed by means of association statistics and formal meta-analysis, respectively. Results PCR status correlated with both TNM stage (stage I to II v III; PCR positivity, 95.1% v 46.6%; P < .0001) and disease recurrence (PCR positive v negative; relapse rate, 16.8% v 8.7%; P < .0001). PCR positivity was also associated with worse overall (hazard ratio [HR], 5.08; 95% CI, 1.83 to 14.08; P = .002) and disease-free (HR, 3.41; 95% CI, 1.86 to 6.24; P < .0001) survival. Statistical heterogeneity was significant, underscoring the variability among overall effect estimates across studies; metaregression and subgroup analysis did not identify clear-cut sources of heterogeneity, although some study design variables were suggested as potential causes. Conclusion PCR status of SLN appears to have a clinically valuable prognostic power in patients with melanoma. Although the heterogeneity of the studies so far published warrants caution to avoid overestimating the favorable results of pooled data, our findings strongly support additional investigation in this field.

Objective Single-surgeon cohorts assessing robotically assisted video-assisted thoracic (RA-VATS) lobectomy have reported good outcomes, but there are little data regarding multiple surgeons applying a standard technique in separate hospitals. The purpose of this study was to show how a standardized robotic technique is both safe and reproducible between surgeons and institutions. Methods From July 1, 2012, to October 1, 2013, patients undergoing RA-VATS lobectomy for both benign and malignant disease were identified from a prospectively collected database of two thoracic surgeons from different hospitals within the same healthcare system and retrospectively analyzed. Each surgeon employed an identical “rule of 10” completely port-based approach through all 128 cases. The primary end points of the study were in-hospital and 30-day mortality. Secondary end points were differences in morbidity and perioperative outcomes between the two surgeons based on their “rule of 10” technique. Results A total of 128 cases were performed with 121 lobectomies, 3 bilobectomies, and 4 pneumonectomies for both malignant and benign disease. Each surgeon had 64 cases without a single in-hospital or 30-day mortality. Overall morbidity was 16.4%. Each surgeon had one readmission and take back to operating room (a washout and a mechanical pleurodesis). The most common complication was prolonged air leak (38.1%, 8/21 patients). There was no statistical difference in length of stay, complications, severity of illness, and clinical staging between the two surgeons. There was a significant difference in resected lymph nodes (11.79 vs 14.45, P = 0.0086). Compared with published national meta-analysis on RA-VAT lobectomies, there was a significantly reduced length of stay (4.2 vs 6 days, P = 0.0436) and bleeding (0.8 vs 1.8%, P = 0.0003). Nodal upstaging from cN0 to pN1 was 8% and cN0 to pN2 was 2% for an overall nodal upstaging of 10% for stage I nonsmall cell lung cancer. Conclusions By standardizing how a robotic lobectomy is performed, we were able to show that RA-VATS lobectomy is safe and may allow for the expansion of minimally invasive lobectomy to surgeons who otherwise have failed to adopt traditional VATS. When compared with the most recent national meta-analysis, we had reduced morbidity, mortality, bleeding, and length of stay. Robotic nodal upstaging for stage I nonsmall lung cancer was consistent with larger multicenter study. We hope that these results will help lead to the standardization robotic lobectomy and a larger multisurgeon/institutional study that could pave the way for greater adoption of minimally invasive lobectomy.

(1) Background: Locoregional lymphadenectomy (LND) in adrenocortical carcinoma (ACC) may impact oncological outcome, but the findings from individual studies are conflicting. The aim of this systematic review and meta-analysis was to determine the oncological value of LND in ACC by summarizing the available literature. (2) Methods: A systematic search on studies published until December 2020 was performed according to the PRISMA statement. The primary outcome was the impact of lymphadenectomy on overall survival (OS). Two separate meta-analyses were performed for studies including patients with localized ACC (stage I–III) and those including all tumor stages (I–IV). Secondary endpoints included postoperative mortality and length of hospital stay (LOS). (3) Results: 11 publications were identified for inclusion. All studies were retrospective studies, published between 2001–2020, and 5 were included in the meta-analysis. Three studies (N = 807 patients) reported the impact of LND on disease-specific survival in patients with stage I–III ACC and revealed a survival benefit of LND (hazard ratio (HR) = 0.42, 95% confidence interval (95% CI): 0.26–0.68). Based on results of studies including patients with ACC stage I–IV (2 studies, N = 3934 patients), LND was not associated with a survival benefit (HR = 1.00, 95% CI: 0.70–1.42). None of the included studies showed an association between LND and postoperative mortality or LOS. (4) Conclusion: Locoregional lymphadenectomy seems to offer an oncologic benefit in patients undergoing curative-intended surgery for localized ACC (stage I–III).

3557 Background: Mismatch repair deficient/microsatellite instability high (dMMR/MSI-H) colorectal cancer (CRC) defines a molecular subtype with distinct clinicopathologic characteristics including an excellent response to immunotherapy. Although BRAF mutations are established as a negative prognostic marker in CRC, whether they retain their negative prognostic impact in or alter the response to immunotherapy in dMMR/MSI-H CRC remains unknown. Herein, we present a systematic review and meta-analysis of the impact of BRAF mutations on the overall survival (OS) and immune checkpoint inhibitor (ICI) response in dMMR/MSI-H CRC. Methods: Studies published from inception to 26 January 2021 were searched in PubMed, Embase, and major conference proceedings (AACR, ASCO, and ESMO). Eligible studies included the following: 1) observational studies reporting outcomes based on BRAF mutation status in dMMR/MSI-H CRC patients and 2) experimental studies of ICI reporting outcomes based on BRAF mutation status in dMMR/MSI-H CRC patients. A summary hazard ratio (HR) was calculated for OS in BRAF mutated ( BRAFmut) vs. BRAF wild type ( BRAFwt) patients (pts) with the random effects meta-analysis (REM). A summary odds ratio (OR) was calculated for objective response rate (ORR) in BRAFmut vs. BRAFwt pts treated with ICI with the REM. Results: Database search conducted according to PRISMA guidelines found 4221 studies in total. Initial screening identified 30 studies and after full-text review, 9 studies (N = 4158 pts) were included for the meta-analysis of prognosis (analysis A) and 3 studies (N = 178 pts) were included for the meta-analysis of ICI response (analysis B). The outcome measures are summarized in the table below. Analysis A showed that in stage I-IV dMMR/MSI-H CRC pts, BRAFmut was associated with worse OS than BRAFwt (HR 1.57, 1.23-1.99). The heterogeneity was low (I2 = 21%). Subgroup analysis showed no significant difference in the prognostic impact of BRAF mutation status between stage IV only and stage I-IV CRC pts. Analysis B showed no difference in ORR (OR 1.04, 0.48-2.25) between BRAFmut vs. BRAFwt dMMR/MSI-H pts who received ICI. The heterogeneity was low (I2 = 0%). Conclusions: BRAF mutations retain their negative prognostic impact in dMMR/MSI-H stage I-IV and stage IV CRC but are not associated with differential ICI response. Limitations include the following: analysis A was based on retrospective studies; also, the impact of BRAF status on the survival outcome of ICI could not be assessed due to limited number of studies.[Table: see text]

Abstract OBJECTIVES The role of segmentectomy in early-stage non-small-cell lung cancer (NSCLC) remains a matter of debate. We performed a meta-analysis to evaluate the oncological outcomes following segmentectomy versus lobectomy for stage I, stage IA only and stage IA &lt;2 cm only. METHODS We systematically searched the literature for articles reporting on overall survival (OS), cancer-specific survival (CSS) or recurrence-free survival (RFS). The hazard ratios (HRs) were retrieved and pooled using an inverse variance-weighted approach. RESULTS Twenty-eight studies were included in the analysis. In stage I, segmentectomy was found to be inferior to lobectomy for all 3 outcomes with HR: 1.25 (P = 0.01) for OS, 1.59 (P = 0.02) for CSS and 1.40 (P &lt; 0.001) for RFS. In stage IA, the differences were significant for OS and CSS, though not for RFS with HR: 1.31 (P = 0.04), 1.56 (P = 0.02) and 1.22 (P = 0.11), respectively. In stage IA &lt;2 cm, no significant differences were found between segmentectomy and lobectomy with HR: 1.13 (P = 0.37) for OS, 1.02 (P = 0.95) for CSS and 1.24 (P = 0.11) for RFS. CONCLUSIONS For stages I and IA, lobectomy showed superior results whereas for tumours &lt;2 cm, our study did not find significant differences in oncological outcomes between both groups. These results suggest that segmentectomy might be a valuable alternative to lobectomy for NSCLC in tumours &lt;2 cm.
