The prognosis of patients with hypopharyngeal cancer (HPC) remains poor. Our study aims to investigate the prognostic impact of cortactin in patients with HPC and its role for tegafur-uracil (UFUR) maintenance after adjuvant chemoradiotherapy (CRT). Patients who were diagnosed to have HPC and underwent laryngopharyngectomy followed by adjuvant CRT were enrolled into our study. Immunohistochemical staining was performed for cortactin evaluation. Kaplan-Meier curves were depicted for recurrence-free survival (RFS) and overall survival (OS). A total of 157 patients were enrolled into our study. After stratified by cortactin, 53 patients were cortactin (+) and 104 patients were cortactin (-). The median RFS was 86.7 months in cortactin (-) and 10.2 months in cortactin (+) (P < 0.001). The median OS was 93.4 months in cortactin (-) and 16.9 months in cortactin (+) (P < 0.001). Patients were further classified according to UFUR maintenance or not after adjuvant CRT. In cortactin (+) patients, the median RFS and OS were 13.6 months versus 7.0 months (P = 0.006) and 24.0 months versus 10.0 months (P < 0.001) in UFUR (+) and UFUR (-), respectively. In cortactin (-) patients, the median RFS and OS were 96.0 months versus 72.2 months (P = 0.262) and 98.5 months versus 105.0 months (P = 0.665) in UFUR (+) and UFUR (-), respectively. Cortactin has a significantly impact in HPC patients. UFUR maintenance provided survival benefits in patients with cortactin (+) after adjuvant CRT.

The efficacy of adjuvant chemotherapy (ACT) in elderly patients with completely resected p-stage II-IIIA non-small-cell lung cancer (NSCLC) remains unclear because all previous randomized controlled trials on ACT have been conducted among patients aged <75 years. Thus, this study aimed to evaluate the effectiveness of ACT in elderly patients with completely resected NSCLC.
We extracted the nationwide data of 812 patients aged ≥75 years who underwent lobectomy with mediastinal nodal dissection in 2010 and were diagnosed with p-stage II-IIIA NSCLC, from nationwide registry data accumulated in 2016.
We classified the 812 patients into 2 groups based on the ACT administration status and analyzed the differences in their postoperative overall survival (OS).
Overall, 295 patients received ACT (36.3%; group A), whereas 517 patients did not (63.70%; group N). Group A showed significantly better OS as a whole (hazard ratio [HR]: 0.650 [95% confidence interval {CI}: 0.526-0.804]), in the p-stage II subset (HR: 0.688 [95% CI: 0.513-0.925]), and p-stage IIIA subset (HR: 0.547 [95% CI: 0.402-0.743]) than group N. Even after propensity score matching, group A showed significantly better OS as a whole (HR: 0.626 [95% CI: 0.495-0.792]), in the p-stage II subset (HR: 0.690 [95% CI: 0.493-0.964]), and p-stage IIIA subset (HR: 0.554 [95% CI: 0.398-0.772]) than group N.
ACT is recommended even in elderly patients with completely resected p-stage II-IIIA NSCLC. Hence, physicians should not avoid ACT in patients with completely resected NSCLC based solely on age.

BACKGROUND: This retrospective single-center cohort study evaluated the efficacy and safety of a combination of neoadjuvant luteinizing hormone-releasing hormone (LHRH) antagonist and tegafur-uracil (UFT) therapy (NCHT) and investigated the medical records of patients with high-risk PCa who underwent robot-assisted radical prostatectomy (RARP). The therapy was followed by RARP for high-risk PCa.
METHODS: The enrolled patients were divided into two groups: low-intermediate-risk PCa patients who underwent RARP without neoadjuvant therapy (non-high-risk) and those who underwent NCHT followed by RARP (high-risk group). This study enrolled 227 patients (126: non-high-risk and 101: high-risk group). Patients in the high-risk-group had high-grade cancer compared to those in the non-high-risk-group.
RESULTS: At the median follow-up period of 12.0 months, there were no PCa deaths; two patients (0.9%) died of other causes. Twenty patients developed biochemical recurrence (BCR); the median time until BCR was 9.9 months after surgery. The 2-year biochemical recurrence-free survival rates were 94.2% and 91.1% in the non-high-risk and high-risk-group, respectively (p = 0.465). Grade ≥3 NCHT-related adverse events developed in nine patients (8.9%).
CONCLUSIONS: This study indicates that combining neoadjuvant LHRH antagonists and UFT followed by RARP may improve oncological outcomes in patients with high-risk PCa.

UNASSIGNED: Half of the population of non-small cell lung cancer (NSCLC) patients are older than 70 years and have limited therapeutic options due to poor tolerance and being excluded in most clinical trials. Anlotinib hydrochloride, a novel oral multi-target tyrosine kinase inhibitor, has been approved for the standard third-line treatment for NSCLC in China. Herein we report an elderly NSCLC patient without any driver gene mutations who was undergoing anlotinib as a front-line treatment and who achieved long-term survival.
UNASSIGNED: The 77-year-old male patient was admitted to the hospital for chest tightness after engaging in physical activity for a week. The patient has been diagnosed with stage IIIB driver gene-negative squamous cell lung carcinoma. After that, he was treated with anlotinib for 2 years and 10 months from the first diagnosis until the last disease progression. Briefly, anlotinib combined with platinum-based chemotherapy was performed as the first-line therapy over six cycles. After 6 more cycles of anlotinib monotherapy maintenance, disease progression occurred. Then, anlotinib combined with tegafur was administered as a salvage treatment, and the disease was controlled again. After 29 cycles of anlotinib combined with tegafur regimens, the disease progressed finally. The patient achieved a total of 34 months of progression-free survival after anlotinib was used as the front-line treatment. He is still alive with a good performance status now (performance status score: 1).
UNASSIGNED: This patient achieved long-term survival using anlotinib as a front-line regimen combined with chemotherapy.

UNASSIGNED: In Japan, adjuvant tegafur-uracil (UFT) chemotherapy is recommended for patients with completely resected, stage I NSCLC. This treatment requires real-world re-evaluation because of recent advances in target-based and immuno-oncological treatments and refinement of lung cancer staging.
UNASSIGNED: The Japan Clinical Oncology Group (JCOG) 0707, a phase 3 trial comparing the benefits of UFT and S-1 (tegafur-gimeracil-oteracil) in patients with completely resected stage I NSCLC (T1 >2 cm and T2 in the TNM sixth edition), was conducted in Japan. A multicenter observational cohort study (Comprehensive Support Project for Oncology Research [CSPOR]-LC03) was also conducted for those patients excluded from JCOG 0707 during the study enrollment period. Physicians from institutions that participated in JCOG 0707 retrospectively assessed the medical records of each patient. The efficacy of UFT was evaluated in the CSPOR-LC03 cohort.
UNASSIGNED: In the entire study population (n = 5005), patients treated with UFT (n = 1549) had significantly longer overall survival (OS) than those without any adjuvant chemotherapy (n = 3338). There was no significant difference in OS between the patients treated with UFT (n = 1061) and those without adjuvant chemotherapy (n = 1484) in the JCOG 0707-eligible population (logrank p = 0.755). For tumors without ground-glass attenuation and size greater than 3 cm, patients treated with UFT had significantly longer survival than those without adjuvant chemotherapy, on univariate but not on multivariate analysis.
UNASSIGNED: There was no significant difference in OS between the patients treated with UFT and those without adjuvant chemotherapy in the clinical trial-eligible population. Adjuvant UFT for patients with completely resected NSCLC may be recommended only in patients with a tumor without ground-glass attenuation and size greater than 3 cm. In patients with node-negative early NSCLC, further study is needed to select patients who will benefit from adjuvant chemotherapy.

BACKGROUND: Adjuvant tegafur-uracil therapy has prolonged postoperative survival in patients with non-small cell lung cancer. Some patients experience treatment discontinuation due to gastrointestinal disorders such as anorexia, and the associated factors and the impact of lobectomy remain unclear. This study aimed to assess the postoperative esophageal displacement after lobectomy and to clarify its impact on the continuity of tegafur-uracil treatment.
METHODS: Patients who received adjuvant tegafur-uracil therapy after lobectomy between April 2009 and March 2019 were retrospectively analyzed. Patient background, perioperative characteristics, treatment findings, and the degree of esophageal displacement measured by computed tomography were compared between the treatment completion group and the discontinuation group. A subgroup comparative analysis was further performed in the groups divided according to the degree of esophageal displacement.
RESULTS: A total of 68 patients were reviewed, including 41 males and 27 females with a mean age of 66.2 years old. A total of 41 patients completed the 2-year adjuvant treatment and 27 patients discontinued it. The overall survival and relapse-free survival between the two groups were statistically significant (p = 0.027, p = 0.010). The degree of esophageal displacement at the Th7 level was a significant predictor of treatment discontinuation (p = 0.046, odds ratio [OR]: 1.138, 95% confidence interval [CI]: 1.002-1.291). Among the patients with a high degree of esophageal displacement above the baseline determined from the receiver operating characteristic curve, the cause of discontinuation was anorexia, which was significant in multivariate analysis (p = 0.013, OR: 14.72, 95% CI: 1.745-124.2).
CONCLUSIONS: Our study suggested that anatomical displacement of the esophagus after lobectomy may affect the discontinuation of oral adjuvant chemotherapy in patients with lung cancer.

Metronomic chemotherapy inhibits tumor growth by continuous administration of lower-dose chemotherapy. Our study aimed to demonstrate the outcomes of metronomic chemotherapy with tegafur-uracil in locally advanced head and neck squamous cell carcinoma (LA HNSCC). This was a retrospective study including 240 patients with LA HNSCC. After standard treatment, 96 patients were further treated with metronomic tegafur-uracil, and 144 patients were not. No statistical differences were found between both groups with regard to sex, clinical stage, or primary treatment choice. There were more hypopharyngeal cancers and more patients with poor clinicopathological features, including lymphovascular invasion, extranodal extension, and positive margins in the tegafur-uracil group. The median follow-up duration was 31.16 months. Overall survival (OS) was not reached in the tegafur-uracil group and was 54.1 months in the control group (p = 0.008). The median disease-free survival (DFS) was 54.5 months in the tegafur-uracil group and 34.4 months in the control group (p = 0.03). Neither group reached distant metastasis-free survival (DMFS, p = 0.02). In patients with LA HNSCC, adding tegafur-uracil as metronomic chemotherapy after either curative surgery with adjuvant chemoradiotherapy or definitive concurrent chemoradiotherapy significantly improved the OS, DFS, and DMFS with tolerable adverse events.

The 3-year disease-free survival rate of the twice-daily regimen was not inferior to that of the conventional three-times-daily regimen, and the twice-daily regimen did not lead to an increase in adverse events. The effectiveness of the twice-daily regimen highlights an increased number of treatment options for patients. This will facilitate personalized medicine, particularly for elderly or frail patients who may experience more severe side effects from the combination therapy.
Tegafur-uracil (UFT)/leucovorin calcium (LV) is an adjuvant chemotherapy treatment for colorectal cancer. We conducted a multicenter randomized trial to assess the noninferiority of a twice-daily compared with a three-times-daily UFT/LV regimen for stage II/III colorectal cancer in an adjuvant setting.
Patients were randomly assigned to group A (three doses of UFT [300 mg/m2 per day]/LV [75 mg per day]) or B (two doses of UFT [300 mg/m2 per day]/LV [50 mg per day]). The primary endpoint was 3-year disease-free survival.
In total, 386 patients were enrolled between July 28, 2011, and September 27, 2013. The 3-year disease-free survival rates of group A (n = 194) and B (n = 192) were 79.4% and 81.4% (95% confidence interval, 72.6-84.4-74.5-85.9), respectively. The most common grade 3/4 adverse events in group A and B were diarrhea (3.9% vs. 7.3%), neutropenia (2.9% vs. 1.6%), increase in aspartate aminotransferase (4.0% vs. 3.9%), increase in alanine aminotransferase (6.2% vs. 6.8%), nausea (1.7% vs. 3.4%), and fatigue (1.1% vs. 2.3%).
Group B outcomes were not inferior to group A outcomes, and adverse events did not increase.

In Japan, oral administration of tegafur-uracil is recommended as postoperative adjuvant chemotherapy for patients diagnosed with primary lung adenocarcinomas of >2 cm size and staged as IA, IB, and IIA. Reports on chemotherapy-induced pericardial effusion are rare. Herein, we report a rare case of tegafur-uracil-induced pericardial effusion during postoperative adjuvant chemotherapy for primary lung cancer. A 60-year-old man underwent left lower lobectomy and mediastinal lymph node dissection for left lower lung adenocarcinoma. Lung cancer was staged as IB, and tegafur-uracil was administered as postoperative adjuvant chemotherapy from 1 month after the surgery. A computed tomography (CT) scan revealed a pericardial effusion 5 months after the surgery. A malignant pericardial effusion was suspected, and tegafur-uracil was discontinued. Pericardiocentesis could not be performed owing to a small amount of pericardial effusion. An 18 F-fluorodeoxyglucose (FDG) positron emission tomography/CT scan revealed no abnormal FDG uptake. During a short follow-up period after discontinuation of tegafur-uracil, a CT scan revealed a decrease in pericardial effusion, suggesting that the pericardial effusion was induced by tegafur-uracil. Follow-up of pericardial effusion is required while administering tegafur-uracil. In cases of pericardial effusion without symptoms and no suspicious metastatic lesions in other organs, we should be concerned about tegafur-uracil-induced pericardial effusion.

BACKGROUND: Lymphovascular invasion (LVI), which includes vascular or lymphatic invasions, is a representative prognostic factor even in patients with resected stage IA non-small cell lung cancer (NSCLC). Because tegafur-uracil is effective on cancers with LVI, we conducted a multi-center single-arm phase II study to estimate the efficacy of adjuvant tegafur-uracil in patients with LVI-positive stage IA NSCLC.
METHODS: Patients with completely resected LVI-positive stage IA NSCLC were registered. LVI was diagnosed by consensus of two of three pathologists. Adjuvant chemotherapy consisted of 2 years of oral tegafur-uracil at 250 mg/m2/day. Fifty-five patients from 7 institutions were enrolled from June 2007 to September 2012.
RESULTS: Among the 52 eligible patients, 36 (69.2%) completed the treatment course. There were 39 male and 13 female patients. The observation period was calculated as 562 to 3107 days using the reverse Kaplan-Meier method. The 5-year overall and relapse free survival rates were 94.2 and 88.5% respectively, which were significantly better than that of any other studies conducted on patients with LVI-positive stage IA NSCLC. Notably, the overall survival rate was 15% better than that of our prior retrospective study. The retrospective analysis of stage IA NSCLC patients who had received an operation in the same period revealed that the 5-year overall survival rate of the LVI positive group was 73.6% when adjuvant chemotherapy was not applied. Among 55 safety analysis sets, 4 cases of grade 3 hepatic function disorder (9.1%) and 5 cases of grade 2 anorexia (10.9%) were most frequently observed. No grade 4 adverse effects were encountered.
CONCLUSIONS: A 2-year course of oral tegafur-uracil administration is feasible and might have a significant benefit in the adjuvant treatment of LVI-positive stage IA NSCLC.
