Background: Patient-reported outcomes (PROs) are validated tools to assess the impact of efficacy and toxicities of cancer treatments on patients' health status. Because of the demonstrated little reliability of humans in reporting memories of painful experiences, this work explores the reliability of cancer patients in reporting chemotherapy-related toxicities.
Aim: This study aims to evaluate the concordance between toxicities experienced by the patients during chemotherapy and toxicities reported to the doctor at the end of the cycles.
Methods: Questionnaires concerning chemotherapy-related toxicities were administered on days 2, 5, 8, 11, 14, and 17 of each chemo cycle and at the end of the same cycle to patients undergoing adjuvant chemotherapy. The co-primary end-points were Lins's concordance correlation coefficient (CCC) and mean difference between real-time and retrospective toxicity assessments.
Results: In total, 7182 toxicity assessments were collected from 1096 questionnaires. Concordance was observed between the retrospective evaluations and the toxicity assessments at early (day 2), peak (maximum toxicity), late (day 14 or 17), and mean real-time evaluations for each chemotherapy cycle (CCC for mean ranging from 0.52 to 0.77). No systematic discrepancy was found between real-time and retrospective evaluations, except for peak, which was systematically underestimated retrospectively.
Conclusions: Toxicities reported by the patients to the doctor at the end of each chemotherapy cycle reflect what they actually experienced without any substantial distortion. This result is very relevant both for the clinical implications in daily patients' management and in the light of the current growing impact on digital monitoring of PROs.

Objective: Esophageal cancer (EC) ranks eighth among cancers in cancer-related deaths globally, and ~44% of new cases occur in China. We sought to describe the clinical characteristics and treatment landscape of EC in China before the approval of immunotherapy in 2020.
Methods: CHANNEL was a large, retrospective study using patient-level data from 14 hospitals/cancer centers across China, including adults initiating therapy for newly diagnosed EC (January to December 2018).

Introduction: Small cell neuroendocrine carcinoma of the urinary tract (SCNEC-URO) has an inferior prognosis compared to conventional urothelial carcinoma (UC). Here, we evaluate the predictors and patterns of relapse after surgery.
Materials And Methods: We identified a definitive-surgery cohort (n = 224) from an institutional database of patients with cT1-T4NxM0 SCNEC-URO treated in 1985-2021.

Background: Pulmonary function assessment is mandatory before oncological lung resection surgery. To do so, subjects undergo a pulmonary function test (PFT) and the calculation of predicted postoperative (PPO) values to estimate the residual lung function after surgery. The aim of this study is to evaluate the use of anatomical formulae in estimating postoperative pulmonary function in patients undergoing minimally invasive surgery (MIS).

Background And Objective: Lung cancer recurrence after complete surgical resection of early-stage T1-T2N0 non-small cell lung cancer (NSCLC) remains a problem due to unrecognized micrometastatic disease. The objective of this review is to present and summarize data from major randomized trials in which have studied the survival benefit of adjuvant therapy for early-stage NSCLC.
Methods: Information used to write this paper was collected from PubMed and the National Clinical Trial registry from the National Library of Medicine.

Background: Perioperative treatment of locally advanced non-small cell lung cancer (NSCLC) is attracting attention. The effect of neoadjuvant tyrosine kinase inhibitor (TKI) therapy on postoperative long-term outcomes in patients with driver gene mutations remains unclear. The aim of this study was to clarify the long-term survival outcomes of patients with stage III NSCLC harboring driver gene mutations who received preoperative TKI therapy.
