The purpose of this phase II trial was to assess the efficacy and toxicity of paclitaxel and nedaplatin (TN) as the initial postoperative adjuvant chemotherapy for uterine cervical cancer with lymph node metastases (LNM). Patients with FIGO stage IB1-IIA2 squamous cell carcinoma of the uterine cervix were enrolled. Histological confirmation of LNM was mandatory.

Association of preoperative serum CRP with PD-L1 expression in 508 patients with non-small cell lung cancer: A comprehensive analysis of systemic inflammatory markers.

Objectives: Programmed death-1 (PD-1) and programmed death-ligand 1 (PD-L1) inhibitors have been approved as a standard therapy for metastatic non-small cell lung cancer (NSCLC). Although PD-L1 expression serves as a predictive biomarker for the efficacy of immunotherapy, there are no established biomarkers to predict the expression of PD-L1. The inflammatory markers C-reactive protein (CRP) and neutrophil-lymphocyte ratio (NLR) were recently shown to predict the efficacy of nivolumab for NSCLC patients.

Background: Regorafenib is an oral multikinase inhibitor with a proven survival benefit for metastatic colorectal cancer patients. The KSCC1402/HGCSG1402 study investigated the prophylactic effect of oral dexamethasone (DEX) on regorafenib-related fatigue and/or malaise.

Patients And Methods: Patients who progressed after standard chemotherapy were randomized 1: 1 to a DEX group (2 mg/day; days 1-28) with regorafenib or a placebo group with regorafenib.

The C-Reactive Protein/Albumin Ratio is a Novel Significant Prognostic Factor in Patients with Malignant Pleural Mesothelioma: A Retrospective Multi-institutional Study.

Background: Malignant pleural mesothelioma (MPM), a devastating neoplasm, is traditionally considered to be resistant to antitumor therapy. Identification of clinical prognostic indicators is therefore needed. Although the C-reactive protein/albumin ratio (CAR) has been used to predict the prognosis of many types of malignancy, its utility in patients with MPM is unknown.

PD-L1 expression according to the EGFR status in primary lung adenocarcinoma.

Objectives: It was reported that programmed cell death-ligand 1 (PD-L1) expression is associated with smoking and wild-type epidermal growth factor receptor (EGFR) in lung adenocarcinoma. However, the association between PD-L1 expression and EGFR mutation site in EGFR mutation-positive lung adenocarcinoma is unclear.

Materials And Methods: We retrospectively examined the relationship between PD-L1 expression and EGFR status in 441 surgically resected primary lung adenocarcinomas.

Factors involved in early lenvatinib dose reduction: a retrospective analysis.

Lenvatinib, a multi-tyrosine kinase inhibitor, has been proven to be an effective treatment option for patients with iodine-131-refractory thyroid cancer. Many adverse effects of lenvatinib have been reported; thus, dose reduction is common. However, a few studies have analyzed the causes of lenvatinib dose reduction in daily clinical practice.

Clinical Impact and Risk Factors for Skeletal Muscle Loss After Complete Resection of Early Non-small Cell Lung Cancer.

Background: A relationship between sarcopenia diagnosed by skeletal muscle area (SMA) and poor prognosis in cancer patients has recently been reported. This study aimed to clarify the clinical significance of postoperatively decreased SMA in patients with early non-small cell lung cancer (NSCLC).

Methods: This study selected 101 patients with pathologic stage 1 NSCLC who had undergone pre- and postoperative (~ 1 year) computed tomography scans and lobectomy between 2005 and 2010 at Kyushu University Hospital.

Tofogliflozin decreases body fat mass and improves peripheral insulin resistance.

The impact of tofogliflozin, a sodium-glucose co-transporter-2 inhibitor, on peripheral glucose uptake in patients with type 2 diabetes mellitus (T2DM) was investigated using the hyperinsulinaemic-euglycaemic clamp method in a single-arm, open-label study. The following variables were compared between before and after tofogliflozin administration for 12 weeks in 16 patients with T2DM who were receiving dipeptidyl peptidase-4 inhibitor treatment: body weight (BW); blood pressure; glucose metabolism; liver function; lipid profile; and body composition. Peripheral glucose uptake (M value and M/I ratio) was examined by the hyperinsulinaemic-euglycaemic clamp method.

The combination of paclitaxel and carboplatin as second-line chemotherapy can be a preferred regimen for patients with urothelial carcinoma after the failure of gemcitabine and cisplatin chemotherapy.

There is no established standard second-line chemotherapy after the failure of the first-line cisplatin-based chemotherapy for patients with advanced or metastatic urothelial carcinoma. With regards to second-line chemotherapy, methotrexate, vinblastine, doxorubicin and cisplatin (MVAC) was used from July 2009 onwards, and paclitaxel and carboplatin (TC) was introduced in April 2014 at the National Kyushu Cancer Center. The present study aimed to assess the prognostic factors for overall survival (OS) in second-line treatment that included best supportive care (BSC), and the tolerability and efficacy of TC chemotherapy.

Low Visceral Fat Content Is a Negative Predictive Marker for Bevacizumab in Metastatic Colorectal Cancer.

Aim: This study aimed to clarify the predictive impact of visceral fat on response to bevacizumab in patients with metastatic colorectal cancer (mCRC).

Patients And Methods: Pretreatment computed tomography was used to measure visceral fat area (VFA) and patients with mCRC receiving first-line chemotherapy with/without bevacizumab were divided by median VFA value into two groups: high VFA and low VFA.

Results: In the bevacizumab-treated group, patients with low VFA had significantly shorter overall survival (OS) than patients with high VFA in univariate (median=21.

Prognostic impact of controlling nutritional status score in resected lung squamous cell carcinoma.

Background: The preoperative immune-nutritional status has been shown to predict the postoperative prognosis in various types of cancer; however, the prognostic significance of the controlling nutritional status (CONUT) score in resected lung squamous cell carcinoma (SCC) has yet to be elucidated.

Methods: A total of 108 patients with resected lung SCC were analyzed for their clinicopathological factors, including the CONUT score, which can be calculated from the serum albumin, total cholesterol, and total peripheral lymphocyte count. The patients were divided into two groups: CONUT low (0 or 1) or high (≥2).

Correction to: S-1 and irinotecan plus bevacizumab as second-line chemotherapy for patients with oxaliplatin-refractory metastatic colorectal cancer: a multicenter phase II study in Japan (KSCC1102).

In the original publication, in Abstract, the sentence that reads as, "Oral S-1 at a dose of 80 mg/m was…………. drug-free interval" should read as, "Oral S-1 at a dose of 40 mg/m was administered twice daily for 2 weeks, followed by a 1-week drug-free interval.

Renal function and urological complications after radical hysterectomy with postoperative radiotherapy and platinum-based chemotherapy for cervical cancer.

Background: We aimed to clarify renal functional changes long term and serious urological complications in women with cervical cancer who undergo radical hysterectomy followed by pelvic radiotherapy and/or platinum-based chemotherapy to treat the initial disease.

Methods: Data on 380 women who underwent radical hysterectomy at the National Kyushu Cancer Center from January 1997 to December 2013 were reviewed. Main outcome measures were the estimated glomerular filtration rate (eGFR) and monitored abnormal urological findings.

Clinical significance of programmed cell death-ligand 1 expression and the immune microenvironment at the invasive front of colorectal cancers with high microsatellite instability.

Immunotherapy is reportedly effective in colorectal cancers (CRCs) with high microsatellite instability (MSI-H); however, the specific cell types that respond to immune checkpoint therapy are unclear. Herein, we aimed to examine the expression of programmed cell death-ligand 1 (PD-L1) and related proteins in MSI-H and microsatellite-stable (MSS) CRCs to investigate the immune microenvironment at the tumor's invasive front. The MSI status was retrospectively assessed in 499 patients undergoing surgical resection of primary CRC; of these, 48 were classified as MSI-H.

Cumulative incidence, risk factors and prognostic impact of venous thromboembolism in Japanese patients with advanced gastric cancer.

Background: Advanced gastric cancer (AGC) and systemic chemotherapy are some of the risk factors for venous thromboembolism (VTE). However, the cumulative incidence, risk factors and prognostic impact of VTE have not been evaluated in Japanese patients with AGC.

Methods: This retrospective study included patients who received fluoropyrimidine-based first-line chemotherapy for AGC between September 2009 and July 2015 at our institution.

Invasive features of small-sized lung adenocarcinoma adjoining emphysematous bullae.

Objectives: Radiologically small-sized adenocarcinomas are special entities of lung cancer, as their radiological and pathological invasiveness determines the surgical procedures applied; however, the clinicopathological features of small-sized lung adenocarcinoma adjoining cystic airspaces (Ca-ADJ) have yet to be fully clarified. The aim of this study was to elucidate the clinicopathological characteristics, including the programmed death ligand 1 (PD-L1) expression, in patients with Ca-ADJ ≤3.0 cm.

A randomized phase II study to assess the effect of adjuvant immunotherapy using α-GalCer-pulsed dendritic cells in the patients with completely resected stage II-IIIA non-small cell lung cancer: study protocol for a randomized controlled trial.

Background: As the toxicity associated with the α-GalCer-pulsed dendritic cell (DC) therapy could be considered to be negligible, its addition to postoperative adjuvant chemotherapy would be expected to greatly improve the therapeutic effect, and could result in prolonged survival. The aim of the present study is to compare the therapeutic efficacy of alpha-galactosylceramide-pulsed DC therapy in patients who have undergone a complete resection of stage II-IIIA non-small-cell lung cancer (NSCLC) followed by postoperative adjuvant therapy with cisplatin plus vinorelbine, to that in patients who did not receive additional treatment (surgical resection plus postoperative adjuvant chemotherapy only).

Methods: Subsequent to the complete resection of NSCLC, followed by the administration of cisplatin plus vinorelbine dual-agent combination adjuvant chemotherapy, patients who satisfy the inclusion criteria will be randomly allocated to either the α-GalCer-pulsed DC immune therapy group, or the standard treatment group.

Maternal sleep and small for gestational age infants in the Japan Environment and Children's Study: a cohort study.

Objectives: Small for gestational age infants have an increased risk of immediate complications, short-term morbidity and mortality, and long-term neurologic and metabolic disorders in adulthood. Previous research has shown that reduced sleep duration is a risk factor for SGA birth. However, only a few studies have evaluated maternal sleep as a risk factor for SGA birth.

Progression-free survival of first-line treatment with molecular-targeted therapy may be a meaningful intermediate endpoint for overall survival in patients with metastatic renal cell carcinoma.

The aim of the present study was to investigate the association between clinical parameters and the overall survival (OS) of Japanese patients with metastatic renal cell carcinoma (mRCC). The medical records of 59 consecutive mRCC patients receiving molecular-targeted therapy were retrospectively assessed. Kaplan-Meier and log-rank analyses were used to evaluate the progression-free survival (PFS) and OS, and a multivariate Cox proportional hazard model was used to analyze the clinical parameters for their prognostic relevance.

Association of MTH1 expression with the tumor malignant potential and poor prognosis in patients with resected lung cancer.

Objectives: The oxidized purine nucleoside triphosphatase, mutT homolog 1 (MTH1), physiologically sanitizes 8-oxo-dGTP in the nucleotide pool. Previous studies indicated that MTH1 is associated with tumor proliferation and invasion in non-small cell lung cancer (NSCLC) cell lines; however, the role of MTH1 in patients with NSCLC remains unclear.

Materials And Methods: Two patient cohorts that underwent surgery for NSCLC in our institution were investigated retrospectively.
