Objectives: Spread through air spaces (STAS) is considered a poor prognostic factor in patients with resected non-small lung cell cancer (NSCLC); however, the clinical significance of STAS extent remains unclear. We hypothesized that the further the tumour cells spread from the tumour edge, the worse the prognosis becomes.
Methods: This study retrospectively reviewed the data of 642 patients with completely resected pathological stage I to III NSCLC between 2008 and 2018.
Background: Sublobar resection is the standard procedure for cT1N0 stage I non-small cell lung cancer (NSCLC) size ≤2 cm. However, its efficacy for high-risk pathologic stage I cases with a preoperative diagnosis of cT1N0 stage I NSCLC size ≤2 cm remains unclear. This study compared the outcomes of sublobar resection with those of lobectomy from a pathologic perspective.

Although SAP is presumed to prevent CHS by gradually restoring cerebral blood flow (CBF), few studies have examined haemodynamic changes, and none have evaluated CBF during the chronic phase of SAP. In the present study, in addition to the clinical outcome of SAP, we measured both resting CBF and cerebrovascular reactivity (CVR) throughout all stages of SAP, including the chronic phase, using quantitative N-isopropyl-p-[I-123] iodoamphetamine (I-IMP) single-photon emission computed tomography (SPECT) and evaluated the effects of SAP on cerebral haemodynamics.

However, the relationship between MSI-H (high) and defective DNA mismatch repair (MMR) is not as straightforward as has been expected. Genome-edited cells carrying Lynch syndrome mutations do not exhibit drastic MSI typical in MSI-H (i.

We ran a post hoc analysis of the IMpower133 phase I/III trial, which randomized patients with ES-SCLC to receive carboplatin/etoposide with either atezolizumab or placebo for 4 cycles, followed by maintenance therapy. We included any systemic antibiotic/probiotic exposure within 42 days prior to treatment initiation and any PPIs treatment within 30 days prior to treatment initiation.

Methods: Over a 1-year period, we prospectively enrolled 40 older adults who received a comprehensive geriatric assessment (CGA) at a geriatric oncology service and initiated a new line of systemic therapy for advanced cancer as inpatients. LAWS is a tailored, self-directed exercise program consisting of leg resistance training and walking.
Introduction: Fluorouracil, leucovorin, irinotecan, and oxaliplatin (FOLFIRINOX) improve overall survival (OS) and progression-free survival (PFS) in patients with pancreatic cancer, compared with gemcitabine (GEM). However, whether PFS is a surrogate marker of OS in pancreatic cancer chemotherapy focusing on FOLFIRINOX or GEM plus nab-paclitaxel remains unknown. We aimed to verify whether PFS can be a surrogate marker of OS in prognosis prediction.

Methods: Patients who underwent radical resection for HCC between 2015 and 2021.
Background: Cluster of differentiation (CD) 155 is a transmembrane protein that belongs to the nectin-like molecule family, which is widely overexpressed in several types of cancer. However, the clinical significance of CD155 in pathologic stage I lung adenocarcinoma remains poorly understood.
Methods: We analyzed 320 patients diagnosed with pathologic stage I lung adenocarcinoma who underwent surgical treatment at Kyushu University Hospital between 2006 and 2015.
Annotating genomic sequence alterations is sometimes a difficult decision, particularly in missense variants with uncertain pathogenic significance and also in those presumed as germline pathogenic variants. We here suggest that mutation spectrum may also be useful for judging them. From the public databases, 982 BRCA1/1861 BRCA2 germline missense variants and 294 BRCA1/420 BRCA2 somatic missense variants were obtained.

However, its usefulness among Japanese people, who have different sensitivities to anticancer drugs and life expectancy, remains unknown. We aimed to prospectively evaluate the utility of the CARG tool for predicting severe CRAE in older Japanese patients with cancer.

However, there are limited clinical data on its efficacy and safety in the real-world. We therefore initiated a retrospective and prospective observational study (NAPOLEON-2).

Crizotinib, a selective ATP-competitive small-molecule inhibitor of c-Met, ALK, and ROS1 tyrosine kinases, has shown activity in cancer models with various types of MET activation.
Methods: The Co-MET study is a single-arm phase 2 trial to assess the safety and efficacy of crizotinib in MET inhibitor-naïve patients with advanced NSCLC harboring MET exon 14 skipping mutation (cohort 1) or high MET gene copy number of ≥ 7 (cohort 2).
Purposes: Polyglycolic acid (PGA) sheets, fibrin glue, and staple line reinforcement are frequently used to prevent air leakage during lung resection. However, the optimal staple-line reinforcement method remains unclear.
Methods: Cranial lung lobes of pigs were used to evaluate different staple line reinforcement methods (n = 6).
Unlabelled: The MUC1-C protein is aberrantly expressed in adenocarcinomas of epithelial barrier tissues and contributes to their progression. Less is known about involvement of MUC1-C in the pathogenesis of squamous cell carcinomas (SCC). Here, we report that the MUC1 gene is upregulated in advanced head and neck SCCs (HNSCC).
