Abstract
Background The Response Assessment in Neuro-Oncology for Brain Metastases (RANO-BM) criteria are the gold standard for assessing brain metastases (BMs) treatment response. However, they are limited by their reliance on 1D, despite the routine use of high-resolution T1-weighted MRI scans for BMs, which allows for 3D measurements. Our study aimed to investigate whether volumetric measurements could improve the response assessment in patients with BMs. Methods We retrospectively evaluated a dataset comprising 783 BMs and analyzed the response of 185 of them from 132 patients who underwent stereotactic radiotherapy between 2007 and 2021 at 5 hospitals. We used T1-weighted MRIs to compute the volume of the lesions. For the volumetric criteria, progressive disease was defined as at least a 30% increase in volume, and partial response was characterized by a 20% volume reduction. Results Our study showed that the proposed volumetric criteria outperformed the RANO-BM criteria in several aspects: (1) Evaluating every lesion, while RANO-BM failed to evaluate 9.2% of them. (2) Classifying response effectively in 140 lesions, compared to only 72 lesions classified by RANO-BM. (3) Identifying BM recurrences a median of 3.3 months earlier than RANO-BM criteria. Conclusions Our study demonstrates the superiority of volumetric criteria in improving the response assessment of BMs compared to the RANO-BM criteria. Our proposed criteria allow for evaluation of every lesion, regardless of its size or shape, better classification, and enable earlier identification of progressive disease. Volumetric criteria provide a standardized, reliable, and objective tool for assessing treatment response.

Abstract
To assist clinicians in formulating treatment strategies for endometrial cancer (EC), this retrospective study explores the relationship between tumor volume and clinical pathological features, as well as prognosis, in patients undergoing staging surgery. Preoperative pelvic MRI examinations were conducted on 234 histologically confirmed EC patients. The ITK-SNAP software was employed to manually delineate the region of interest in the MRI images and calculate the tumor volume (MRI-TV). The analysis focused on investigating the relationship between MRI-TV and the clinical pathological features and prognosis of EC patients. Larger MRI-TV was found to be associated with various adverse prognostic factors (G3, deep myometrial invasion, cervical stromal invasion, lymphovascular space invasion, lymph node metastasis, advanced international federation of gynecology and obstetrics staging, and receipt of adjuvant therapy). The receiver operating characteristic curve indicated that MRI-TV ≥ 8 cm3 predicted deep myometrial invasion, and MRI-TV ≥ 12 cm3 predicted lymph node metastasis. Penalized spline (P-spline) regression analysis identified 14 cm3 of MRI-TV as the optimal prognostic cutoff value. MRI-TV ≥ 14 cm3 was an independent prognostic factor for overall survival and disease-free survival. For patients with MRI-TV ≥ 14 cm3, the disease-free survival rate with adjuvant therapy was superior to that of the sole staging surgery group. This study demonstrates a significant correlation between MRI-TV and clinical pathological features and prognosis in EC. For patients with MRI-TV ≥ 14 cm3, staging surgery followed by adjuvant therapy was superior to sole staging surgery.

Is tumor diameter a risk factor for occult N1 metastasis in patients with peripheral non-small cell lung cancer which is smaller than 3 cm? Updates Surg 2023; 75:2335-2342.

Abstract
The optimum treatment option is surgery for clinical early stage non-small cell lung cancer. Despite all non-invasive and invasive staging effort, occult lymph-node metastasis can be detected in pathological staging. Here, we investigated whether there was any correlation between tumor diameter and occult lymph-node metastasis in N1 stations. Data of patient with non-small cell lung cancer clinical stage 1A were reviewed retrospectively. Those with tumor diameter smaller than 3 cm and pN0-pN1 in pathological staging were included in the study. Overall survival (OS) was calculated by Kaplan-Meier and survival differences between pN0 and pN1 groups were investigated by Log-Rank methods. Cut-off value of tumor diameter for lymph-node metastasis was investigated by Receiver-Operating Characteristics test. Significance between pN0-pN1 and other categorical groups was investigated with Pearson Chi-square or Fisher's exact tests. A total of 257 patients meet to criteria included in the study. Fifty-five (21.4%) of the patients were females. The mean age was 62.7 ± 8.5 and median tumor diameter was 20 mm (Range: 2-30 mm). We detected occult lymph-node metastasis at the N1 stations (pN1) in 33 patients (12.8%) in histopathological examination of resected specimens and lymph-node dissection materials. The cut-off value of tumor diameter was calculated as 21.5 mm for occult lymph-node metastasis by Receiver-Operating Characteristics analysis (Area Under Curved: 70.1%, p = 0.004). There was a significant correlation between pN1 positivity and high tumor diameter (p = 0.02). However, we did not find a correlation between the lymph-node metastasis and age, gender, tumor histopathology, tumor localization, and visceral pleural invasion. Tumor diameter may be an indicator for occult lymph-node metastasis in patients with clinical stage-1A non-small cell lung cancer. This result should be considered in patient with mass which larger than 21.5 mm and planned stereotactic body radiotherapy instead of surgery.

Abstract
Background To investigate the prognostic significance of station 4R lymph node (LN) dissection in patients who underwent operations for right primary non-small cell lung cancer (NSCLC). Methods We performed a retrospective study involving patients with right primary NSCLC who received lobotomy or pneumonectomy with mediastinal LN dissection between January 2011 and December 2017. Propensity score matching was performed. Disease-free survival (DFS) and overall survival (OS) were compared between patients with and without station 4R dissection. Results Our study included 2070 patients, with 207 patients having no station 4R dissection (S4RD− group) and 1863 patients having station 4R dissection (S4RD+ group). The 4R LN metastasis rate was 13.4% (142/1748), higher than that for other mediastinal LN metastases. Compared with the S4RD− group, the S4RD+ group had higher 5-year DFS (48.1% vs. 39.1%, P = 0.009) and OS (54.4% vs. 42.8%, P = 0.025). Station 4R dissection was an independent risk factor for DFS (odds ratio, OR, 1.28, 95% confidence interval, CI, 1.08–1.64, P = 0.007) and OS (OR 1.31, 95% CI 1.04–1.63, P = 0.018). Patients with adjuvant chemotherapy had a better prognosis after station 4R dissection than those without adjuvant chemotherapy (57.4% vs. 52.3%, P = 0.006). The 5-year OS in the station 4R metastasis group was lower than that in the station 4R non-metastasis group (26.9% vs. 44.3%, P = 0.006) among N2 patients. The 5-year OS of the single-station 4R metastasis group was lower than that of the single-station 7 metastasis group (15.7% vs. 51.6%, P = 0.002). Conclusions Station 4R metastasis was the highest among all the mediastinal station metastases in right primary NSCLC patients. Station 4R dissection can improve the prognosis and should be recommended as a routine procedure for these patients.

The impact of pathology grossing protocol measures to improve pathologic nodal staging in lung cancer. Cancer Treat Res Commun 2021; 29:100488. [PMID: 34856512 DOI: 10.1016/j.ctarc.2021.100488] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/22/2021] [Revised: 10/24/2021] [Accepted: 11/07/2021] [Indexed: 11/22/2022]
Abstract
OBJECTIVE Accurate assessment of lymph node (LN) status is essential for proper staging of resected lung cancer specimens. Here, we assessed pathology-centric interventions to increase the number of peribronchial LNs identified and evaluated in anatomic lung cancer resection specimens as part of a quality improvement initiative. MATERIALS AND METHODS All non-small cell lung cancer (NSCLC) anatomic resection specimens from 2017 to 2020 were evaluated, comprising two years pre-intervention and one year post-intervention. We instituted 3 measures to increase peribronchial LN yield: 1) educational grossing sessions for pathology assistants and residents, 2) directions to submit additional peribronchial tissue if no LNs were identified grossly, and 3) a hard-stop prior to sign-out by the attending pathologist if no peribronchial LNs were identified. RESULTS Of the total 227 resection specimens for NSCLC, 107/151 (70.9%) of specimens prior to the intervention had peribronchial LNs identified, whereas after the intervention significantly more (66/76, 86.8%, p < 0.01) specimens had peribronchial LNs identified. In addition, the mean number of peribronchial LNs identified significantly increased from 2.7 ± 3.3 pre-intervention to 4.3 ± 4.0 post-intervention (p < 0.001). Further analysis revealed a strong correlation between peribronchial LN metastases with both overall tumor size and invasive component size (for adenocarcinomas), correlation coefficient 0.974, p < 0.0001. CONCLUSION Establishing focused grossing measures by pathology led to a significant increase in the number of peribronchial LNs identified and assessed during histopathologic evaluation of anatomic lung cancer resection specimens. Larger tumors are more likely to have occult peribronchial LN metastases, which may warrant more aggressive peribronchial LN assessment for larger tumors.

Eur J Radiol 2021; 141:109802. [PMID: 34090112 DOI: 10.1016/j.ejrad.2021.109802] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2021] [Revised: 05/21/2021] [Accepted: 05/26/2021] [Indexed: 12/24/2022]
Abstract
OBJECTIVES To retrospectively investigate whether radiological and clinicopathological characteristics were associated with the presence of stage IA-IIA lung adenocarcinoma in patients at high risk for a postoperative recurrence. MATERIALS AND METHODS Three hundred twelve patients with biopsy-proven node-negative early-stage (IA-IIA) lung adenocarcinoma met the inclusion criteria for this study. Demographics data and histopathological findings were collected from medical records. Computed tomography (CT) performed approximately 1 month before surgery was manually scored using 23 CT descriptors. Univariate analyses were applied to demonstrate an association between clinicopathological and radiological features and 2-/5-year recurrences. Multivariate logistic regression was performed to assess the ability of radiological and clinicopathological features to discriminate low and high-risk factors for recurrence. A ROC curve was used to evaluate prediction performance. RESULTS Univariate analysis revealed that the 2-year recurrence was associated with six radiological features and two clinicopathological features, while 5-year recurrence was associated with five radiological features and two clinicopathological features. A multivariate logistic regression model of combined clinicopathological and radiological features showed that stage IIA (OR = 2.87), solid texture (solid part > 50 %: OR = 4.81; solid part = 100 %: OR = 3.61), pleural attachment (OR = 3.97) and bronchovascular bundle thickening (OR = 2.16) were associated with the independent predictors of 2-year recurrence, and stage IIA (OR = 3.52), solid texture (solid part > 50 %: OR = 3.56; solid part = 100 %: OR = 2.44) and pleural attachment (OR = 4.57) were associated with 5-year recurrence. Combined radiological and clinicopathological features could be significant indicators of 2- and 5-year recurrences (AUC = 0.784 and AUC = 0.815, respectively). CONCLUSIONS The combination of radiological and clinicopathological features has the potential to help predict postoperative recurrence in patients with stage IA-IIA lung adenocarcinomas and guide oncologists and patients whether to undergo additional treatment after surgery.
