Abstract
Background The accuracy of lymph node ratio (LNR) as a prognostic index remains to be proven for gastric cancer patients after neoadjuvant chemotherapy (NACT). This study sought to investigate the prognostic value of LNR in locally advanced gastric cancer (LAGC) patients after NACT. Methods LAGC patients with clinical TNM stages 2–3, Her2(−), and Eastern Cooperative Oncology Group, scores 0–2 are routinely scheduled with NACT. Patients with LAGC after NACT and surgical operation between January 2012 and October 2020 were retrospectively reviewed. The correlation between LNR and survival was investigated. Results Overall, 148 patients were enrolled: 103 with low-LNR (LNR ≤ 30%) and 45 with high-LNR (LNR > 30%). Approximately, 50.5% and 24.4% patients responded to NACT at the primary site in the low-LNR and high-LNR groups, respectively. The overall survival (OS) and progression-free survival (PFS) of low-LNR group were considerably better than those of high-LNR group (3-year OS: 81.9% vs 18.5%, P < 0.001; 3-year PFS: 72.6% vs 13.5%, P < 0.001). In the low-LNR group, OS and PFS were superior in patients with tumor regression grade (TRG) 0–2 than in those with TRG 3 (3-year OS: 89.2% vs 73.2%, P = 0.086; 3-year PFS: 80.3% vs 66.5%, P = 0.036). In association with OS and PFS, the degree of tumor differentiation, TRG, and LNR were identified as predictive factors, and LNR was identified as the independent prognostic factor in univariate and multivariate analyses, respectively. Conclusions LNR is a prospective index of prognosis in patients with LAGC after NACT.

Abstract
BACKGROUND Long-term remission can be achieved by surgery in patients with metastatic renal cell carcinoma (mRCC), without chronic toxicity due to systemic treatment. Data on metastasectomy are mostly based on observations of metachronous metastasis. However, it is unclear whether patients with synchronous oligometastasis may also benefit from surgery alone as an alternative to highly effective systemic treatment combined with resection of the primary tumor. MATERIALS AND METHODS The authors performed an unstructured literature search in PubMed including systematic reviews and meta-analyses. Results are discussed in regard of the current data and clinical practice. RESULTS AND DISCUSSION Although there is no uniform definition for oligometastasis in mRCC, cytoreductive nephrectomy in selected patients seems to be mandatory before metastasectomy is performed in primary oligometastatic RCC. In particular, in those patients with oligometastasis of the lung, bone, central nervous system, liver, adrenal gland, and thyroid, metastasectomy appears to be an important therapeutic option. Ultimately, among the therapeutic options, surgery is also an important therapeutic approach in primary oligometastatic mRCC. A balanced consideration between surgery, other local therapies, and modern systemic treatment demands interdisciplinary decision-making that takes into account the patients' preference.
