Background And Objectives: Patients with metastatic RCC can undergo metastasectomy to improve survival time. Our goal was to provide and compare characteristics and oncological outcomes of RCC patients who underwent complete metastasectomy at a single organ site.
Methods: A total of 138 RCC patients were identified as undergoing complete metastasectomy at a single organ site including adrenal, lung, liver, pancreas, or thyroid. Competing risk regression analysis was used to assess RFS and CSS adjusting for several covariates.
Results: In this highly selected cohort, RFS and CSS was 27% and 84% at 5 years following metastasectomy, respectively. Univariate analysis revealed that removal of multiple tumors, younger age, and a shorter interval between nephrectomy and metastasis was associated with worse RFS. Larger tumors and sarcomatoid histology at nephrectomy was associated with worse CSS. We found no evidence that metastases at the time of RCC diagnosis influenced recurrence or survival. Tumor size, number of metastases resected, and time from nephrectomy to first recurrence was significantly different, but recurrence rates were not found to be significantly different, when compared across all organ sites.
Conclusions: These findings inform clinical and surgical management of select RCC patients with isolated metastasis to one of several organ sites. J. Surg. Oncol. 2016;114:375-379. © 2016 Wiley Periodicals, Inc.

Background: Regorafenib and trifluridine/tipiracil (TFD/TPI) are oral systemic therapies with survival benefit in chemorefractory metastatic colorectal cancer (mCRC) patients, but they are not widely available worldwide. We aimed to evaluate the treatment patterns and outcomes of patients with limited access to these drugs.
Methods: Retrospective study involving 510 patients with mCRC who were treated at five different centers in Brazil, from January 2011 to December 2019.

Surgical treatment of lung metastases originating from head and neck tumors has shown favorable outcomes with low incidence of complications and mortality. This study aims to investigate survival and prognostic factors following pulmonary metastasectomy for head and neck cancers. A comprehensive review of the literature was conducted through the Medline database, focusing on English-language studies related to surgical treatment of lung metastases from head and neck cancers.

Purpose Of The Review: This narrative review aims to provide an overview of recently completed randomized trials and expert consensus recommendations, and their implications for clinical practice and future trial design in patients with de-novo esophagogastric oligometastatic disease (OMD).
Recent Findings: The IKF-575/RENAISSANCE phase III trial showed no significant overall survival difference between systemic therapy alone and systemic therapy combined with local therapy for patients with gastric or gastroesophageal junction cancer and de-novo OMD, except for patients with retroperitoneal lymph node metastases only. The ESO-Shanghai 13 phase II trial demonstrated superiority of adding local therapy to systemic therapy for progression-free and overall survival in oligometastatic esophageal squamous cell carcinoma.

In the United States, there is expected to be about 82,000 cases of renal cell carcinoma (RCC) in 2024. At diagnosis, approximately 65% of patients with RCC will have disease localized to the kidney. For decades, the standard of care for patients with localized RCC has been surgery, which is often curative, followed by radiographic surveillance.

Background And Objectives: Due to heterogeneous characteristics of primary cancers, the efficacy of pulmonary metastasectomy (PM) in nonprimary lung cancers has not been investigated. This study aims to investigate the clinical outcomes of PM for non-primary lung cancer.
Methods: A systematic search for meta-analyses on PM for nonprimary lung cancers was conducted, encompassing publications up to January 3, 2024.
