Clinical outcomes of surgical resection for recurrent lesion after curative esophagectomy for esophageal squamous cell carcinoma: a nationwide, large-scale retrospective study.

ABSTRACT:

Background

Several studies have reported the efficacy of resection for recurrent lesions. However, they involved a limited number of subjects. This study aimed to identify a subset of patients who benefit from surgical resection of recurrent lesions after curative esophagectomy for esophageal squamous cell carcinoma.

Methods

Clinicopathological features of 186 patients with esophageal squamous cell carcinoma who underwent surgical treatment for postoperative recurrent lesions at 37 accredited institutions of the Japanese Esophageal Society were evaluated.

Results

The most common recurrence site was the lymph node (106 cases; 58.6%), followed by the lung (40 cases; 22.1%). Univariate analyses revealed that pN 0-1 at esophagectomy (P = 0.0348), recurrence-free interval of ≥ 550 days (P = 0.0306), R0 resection (P < 0.0001), and absence of severe complications after resection for recurrent lesions (Clavien-Dindo grade < IIIa) (P = 0.0472) were associated with better overall survival after surgical resection. According to multivariate analyses, pN 0-1 (P = 0.0146), lung metastasis (P = 0.0274), recurrence-free interval after curative esophagectomy of ≥ 550 days (P = 0.0266), R0 resection (P = 0.0009), and absence of severe complications after resection for recurrent lesions (Clavien-Dindo grade < IIIa) (P = 0.0420) were independent predictive factors for better overall survival.

Conclusions

Surgical resection of recurrent esophageal squamous cell carcinoma lesions is a useful option, especially for cases involving lower pN stage, lung metastasis, long recurrence-free intervals after esophagectomy, and technically resectable lesions. Surgical risks should be minimized as much as possible.

Project description:Objective: To establish the prognostic value of mean corpuscular volume (MCV) in patients with esophageal squamous cell carcinoma (ESCC) who have undergone esophagectomy. Background: The MCV increases in patients with high alcohol and tobacco consumption. Such a lifestyle can be a risk factor for malnutrition, comorbidities related to those habits, and multiple primary malignancies, which may be associated with frequent postoperative morbidity and poor prognosis. Methods: This study included 1673 patients with ESCC who underwent curative esophagectomy at eight institutes between April 2005 and November 2020. Patients were divided into normal and high MCV groups according to the standard value of their pretreatment MCV. Clinical background, short-term outcomes, and prognosis were retrospectively compared between the groups. Results: Overall, 26.9% of patients had a high MCV, which was significantly associated with male sex, habitual smoking and drinking, multiple primary malignancies, and malnutrition, as estimated by the body mass index, hemoglobin and serum albumin values, and the Geriatric Nutritional Risk Index. Postoperative respiratory morbidity (P = 0.0075) frequently occurred in the high MCV group. A high MCV was an independent prognostic factor for worse overall survival (hazard ratio, 1.27; 95% confidence interval, 1.049–1.533; P = 0.014) and relapse-free survival (hazard ratio, 1.23; 95% confidence interval, 1.047–1.455; P = 0.012). Conclusions: A high MCV correlates with habitual drinking and smoking, malnutrition, and multiple primary malignancies and could be a surrogate marker of worse short-term and long-term outcomes in patients with ESCC who undergo esophagectomy. Mini-Abstract: This multicenter cohort study elucidated that a high pretreatment mean corpuscular volume correlated with habitual drinking and smoking, malnutrition, and multiple primary malignancies, and could be a surrogate marker of worse short-term and long-term outcomes in patients with esophageal squamous cell carcinoma who have undergone curative esophagectomy.

Project description:BackgroundRetroperitoneal soft tissue sarcomas (STS) include a number of histologies but are rare, with approximately 3000 cases in the USA per year. Retroperitoneal STS have a high incidence of local and distant recurrence. The purpose of this study was to review the University of Maryland Medical Center's (UMMC) treatment experience of retroperitoneal STS, where the patient population served represents a diverse socioeconomic and ethnic catchment.MethodsIRB approval was obtained. We constructed a de-identified database of patients diagnosed with retroperitoneal liposarcomas (LPS) or leiomyosarcomas (LMS) treated at UMMC between 2000 and 2013. A total of 49 patients (Pts) with retroperitoneal STS met our eligibility criteria. Kaplan-Meier plots were used to graphically portray progression-free survival (PFS) and overall survival (OS). The log-rank test was used to compare time-to-event distributions.ResultsThe median OS for all patients (Pts) was 6.3 years, and the 2-year OS rate was 81%. The median PFS for all Pts was 1.8 years, and the 2-year PFS rate was 45%. There was no difference in OS and PFS among LMS and LPS patients; the median OS for LMS was 3.8 years vs. LPS 6.4 years (p = 0.33), and the median PFS for LMS was 1.2 years vs. LPS 2.5 years (p = 0.28). There was a significant difference between histology and race (p = 0.001). LPS were primarily Caucasian 86% vs. 14% black, whereas LMS were primarily black 52% vs. 33% Caucasian. OS was influenced by functional status, gender, American Joint Committee on Cancer (AJCC) stage, grade, histology, tumor size, and extent of resection. PFS was influenced by AJCC stage, grade, and extent of resection. Neither adjuvant chemotherapy (1 Pt) nor neoadjuvant/adjuvant radiation therapy (18 Pts) influenced OS or PFS. There was a non-significant difference that Pts who could undergo resection of local recurrence had improved 2-year OS, with 100% LMS and LPS compared to 2-year OS of 71% (LMS) and 78% (LPS) not undergoing resection of local recurrence.ConclusionsThis study suggests a higher incidence of leiomyosarcoma in the African-American population. This study confirms the prognostic importance of grade, tumor size, AJCC stage, histology, and extent of resection in patient outcomes, at a large substantially diverse academic medical center. Future research into the biological features of liposarcoma and leiomyosarcoma Pts imparting these characteristics will be important to define.
