Definition of oligometastatic esophagogastric cancer and impact of local oligometastasis-directed treatment: A systematic review and meta-analysis. Eur J Cancer 2022; 166:254-269. [PMID: 35339868 DOI: 10.1016/j.ejca.2022.02.018] [Citation(s) in RCA: 40] [Impact Index Per Article: 20.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/02/2021] [Revised: 02/11/2022] [Accepted: 02/19/2022] [Indexed: 02/06/2023]
Abstract
BACKGROUND Local treatment (metastasectomy or stereotactic radiotherapy) for oligometastatic disease (OMD) in patients with esophagogastric cancer may improve overall survival (OS). The primary aim was to identify definitions of esophagogastric OMD. A secondary aim was to perform a meta-analysis of OS after local treatment versus systemic therapy alone for OMD. METHODS Studies and study protocols reporting on definitions or OS after local treatment for esophagogastric OMD were included. The primary outcome was the maximum number of organs/lesions considered OMD and the maximum number of lesions per organ (i.e. 'organ-specific' OMD burden). Agreement was considered to be either absent/poor (< 50%), fair (50%-75%), or consensus (≥ 75%). The secondary outcome was the pooled adjusted hazard ratio (aHR) for OS after local treatment versus systemic therapy alone. The ROBINS tool was used for quality assessment. RESULTS A total of 97 studies, including 7 study protocols, and 2 prospective studies, were included. OMD was considered in 1 organ with ≤ 3 metastases (consensus). 'Organ-specific' OMD burden could involve bilobar ≤ 3 liver metastases, unilateral ≤ 2 lung metastases, 1 extra-regional lymph node station, ≤ 2 brain metastases, or bilateral adrenal gland metastases (consensus). Local treatment for OMD was associated with improved OS compared with systemic therapy alone based on 6 non-randomized studies (pooled aHR 0.47, 95% CI: 0.30-0.74) and for liver oligometastases based on 5 non-randomized studies (pooled aHR 0.39, 95% CI: 0.22-0.59). All studies scored serious risk of bias. CONCLUSIONS Current literature considers esophagogastric cancer spread limited to 1 organ with ≤ 3 metastases or 1 extra-regional lymph node station to be OMD. Local treatment for OMD appeared associated with improved OS compared with systemic therapy alone. Prospective randomized trials are warranted.

[PMID: 34743935 DOI: 10.1016/j.yexcr.2021.112884] [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: 08/10/2021] [Revised: 09/26/2021] [Accepted: 10/13/2021] [Indexed: 12/09/2022]
Abstract
The dysregulation of deubiquitinating enzymes (DUBs), which regulate the stability of most cellular proteins, have been implicated in many human diseases, including cancers. Ubiquitin-specific protease 18 (USP18), a member of the DUBs family, functions as a potential tumour promoter in various cancers. However, the biological function and clinical significance of USP18 in esophageal squamous cell carcinomas (ESCC) are still unclear. Here, we found that ESCC tumors had higher USP18 expression compared with that of normal esophageal epithelial tissues, and high USP18 level was significantly correlated with malignant phenotype and shorter survival in patients with ESCC. In functional experiments, USP18 knockdown significantly inhibited ESCC invasion and metastasis in vitro. Consistently, a xenograft assay showed that knockdown of USP18 in ESCC cell suppressed their dissemination to lung tissue in vivo. Furthermore, we showed that USP18 promoted ESCC cell metastasis by inducing ZEB1 mediated epithelial-mesenchymal transition (EMT). Importantly, our results demonstrated that the oncogenic effect of USP18 in ESCC is partially dependent on ZEB1 enhancement. Mechanistic investigations revealed that USP18 directly bound ZEB1 and decreased its ubiquitination to enhance the protein stability of ZEB1 in ESCC cells. Overall, our data highlighted an essential role of USP18 in ESCC metastasis, suggesting that it could be a potential diagnostic and therapeutic target for ESCC.

Jpn J Clin Oncol 2021; 51:786-792. [PMID: 33442741 DOI: 10.1093/jjco/hyaa254] [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: 09/23/2020] [Revised: 10/22/2020] [Accepted: 12/06/2020] [Indexed: 11/13/2022] Open
Abstract
BACKGROUND The aim of this retrospective study is to evaluate the perioperative complications and prognosis of patients with a history of resected esophageal carcinoma who subsequently underwent pulmonary resection of a primary lung cancer. METHODS The study cohort comprised 23 patients who had undergone curative resection of a primary lung cancer following esophagectomy for a primary esophageal carcinoma. Clinical characteristics and surgical outcomes were analyzed. RESULTS The initial treatment for esophageal carcinoma was esophagectomy by thoracotomy in 10 patients and video assisted thoracoscopic surgery in 13. The treatments for lung cancer comprised wedge resection in three patients, segmentectomy in seven and lobectomy in 13. The pulmonary resections were performed by thoracotomy in six and video assisted thoracoscopic surgery in 17. The average operating time for the lung cancer surgeries was 202 min and average blood loss 122 ml. There were no perioperative deaths or severe complications. Three- and Five-year overall survival rates were 78.0% and 68.2%. According to univariate survival analysis, age, restrictive ventilatory impairment and histology of lung cancer were significant predictors of poor prognosis (all P < 0.05). Significantly more of the patients with than without restrictive ventilatory impairment died of other diseases (P = 0.0036). CONCLUSIONS Pulmonary resection for primary lung cancers following esophagectomy for esophageal carcinoma is acceptable in selected patients. Such surgery requires caution concerning intrathoracic adhesions and postoperative prolonged air leakage. Patients with restrictive ventilatory impairment had a poorer prognosis, and the indication for surgery in these patients should be carefully considered.
