Is Sublobar Resection Feasible for High-Risk Pathologic Stage I Non-small Cell Lung Cancer?

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.

An open-label, randomized, controlled trial on the benefit of β-hydroxy-β-methyl butyrate, l-arginine, l-glutamine combination beverages and locomotion training as supportive care for the treatment of unresectable hepatocellular carcinoma using lenvatinib: A pilot study (HELLO study).

Introduction: Hand-foot-skin reaction (HFSR) is the most common side effect of multi-tyrosine kinase inhibitor therapy for unresectable hepatocellular carcinoma (uHCC). Sarcopenia has been reported to be a poor prognostic factor for HCC. Here, we performed a randomized controlled trial (RCT) of the efficacy of a β-hydroxy-β-methyl butyrate/L-arginine/L-glutamine (HMB/Arg/Gln) beverage and locomotion training as supportive care in the treatment of uHCC with lenvatinib.

Declining Prevalence of Human Papillomavirus Co-Infections Among Young Japanese Women With Cervical Cancer and Its Precursors.

Co-infections with human papillomavirus (HPV) of multiple genotypes mainly occur due to increased sexual activity. To address the prevalence and trend of HPV co-infections in Japan, HPV-type-specific data from Japanese women (n = 8128) aged < 40 years and newly diagnosed with cervical abnormalities at 24 hospitals between 2012 and 2023 were analyzed. These included cervical intraepithelial neoplasia grade 1/2 (CIN1/2, n = 2745), CIN3/adenocarcinoma in situ (AIS) (n = 3953), and invasive cervical cancer (ICC, n = 1430).

More subtle microsatellite instability better predicts fluorouracil insensitivity in colorectal cancer patients.

Microsatellite instability (MSI) is now widely used as an indispensable biomarker. 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.

Development of a Leg And Walking Self-exercise (LAWS) program for older adults during cancer treatment.

Purpose: We developed a self-directed Leg And Walking Self-exercise (LAWS) program informed by the Exercise is Medicine initiative and evaluated the feasibility and acceptability of this program in older adults with cancer.

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.

Efficacy of immune checkpoint inhibitors plus platinum-based chemotherapy as 1st line treatment for patients with non-small cell lung cancer harboring HER2 mutations: Results from LC-SCRUM-Asia.

Introduction: HER2 mutations are reported to occur in 2%-5% of all cases of non-small cell lung cancer (NSCLC). The clinical outcomes in patients with HER2-mutant NSCLC treated with immune checkpoint inhibitors (ICIs) plus platinum-based chemotherapy as 1st line treatment still remain unclear.

Methods: Using the large-scale clinico-genomic database of LC-SCRUM-Asia, the clinico-genomic characteristics and therapeutic outcomes of patients with HER2-mutant NSCLC were investigated.

Final Analysis Data and Exploratory Biomarker Analysis of a Randomized Phase 2 Study of Osimertinib Plus Bevacizumab Versus Osimertinib Monotherapy for Untreated Patients With Nonsquamous NSCLC Harboring EGFR Mutations: The WJOG9717L Study.

Introduction: EGFR tyrosine kinase inhibitors have been the standard treatment for patients with NSCLC who have sensitive mutations. This study revealed final analysis survival data, biomarkers, and resistance mechanisms of osimertinib plus bevacizumab or osimertinib monotherapy in previously untreated patients with advanced -positive nonsquamous NSCLC.

Methods: We previously reported the primary results of a randomized, open-label, phase 2 study comparing osimertinib plus bevacizumab with osimertinib monotherapy for this population.

Capmatinib in MET exon 14-mutated non-small-cell lung cancer: final results from the open-label, phase 2 GEOMETRY mono-1 trial.

Background: Capmatinib has previously shown activity in treatment-naive and previously treated patients with non-small-cell lung cancer (NSCLC) and a MET exon 14-skipping mutation (METex14). Here, we report the final outcomes from the phase 2 GEOMETRY mono-1 study with an aim to provide further evidence for the activity of capmatinib.

Methods: In this non-randomised, multi-cohort, open-label, phase 2 trial conducted in 152 centres and hospitals in 25 countries, with patients treated in 95 centres in 20 countries, eligible patients (aged ≥18 years) with MET-dysregulated, EGFR wild-type, and ALK rearrangement-negative advanced NSCLC (stage IIIB/IV) and an Eastern Cooperative Oncology Group performance status of 0 or 1 were assigned to cohorts (1a, 1b, 2, 3, 4, 5a, 5b, 6 and 7) based on their MET status (METex14 or MET amplification) and previous therapy lines.

A phase II study of weekly carboplatin and concurrent radiotherapy in older adults with locally advanced non-small cell lung cancer (LOGIK1902).

Background: Concurrent chemoradiotherapy is the standard therapy for locally advanced non-small cell lung cancer (NSCLC). However, there is little evidence supporting its use in older adults. Low-dose daily carboplatin combined with thoracic radiotherapy is considered a standard regimen for this population.

A dramatic response to an immune checkpoint inhibitor plus chemotherapy in a patient with metastatic metaplastic carcinoma of the breast: A case report.

We present a unique case of metastatic metaplastic breast carcinoma responding dramatically to immunochemotherapy. A 46-year-old Japanese woman with primary metaplastic carcinoma of the breast, which was immunohistochemically confirmed to be triple-negative breast cancer, underwent radical surgery, followed by adjuvant chemotherapy with an anthracycline and a taxane. Since multiple lung metastases were detected two months post-chemotherapy and the primary site was shown to be PD-L1-positive, the immune checkpoint inhibitor (ICI) pembrolizumab plus gemcitabine/carboplatin was initiated.

Bilateral breast metastases from anaplastic lymphoma kinase-positive lung cancer in a male: a case report.

Background: Distant metastases from lung cancer are commonly found in the brain, bone, and liver. Metastases to the breast from non-mammary malignancies are extremely rare, and their clinical presentations remain unclear.

Case Presentation: We herein report a case of bilateral breast metastases from anaplastic lymphoma kinase-positive advanced lung cancer in a 51-year-old Japanese male patient.

Real-world outcomes of FOLFOXIRI plus bevacizumab in patients with metastatic colorectal cancer: the JSCCR-TRIPON study.

Background: FOLFOXIRI plus bevacizumab is a standard first-line chemotherapy for patients with metastatic colorectal cancer (mCRC). However, due to the severe toxicities, this regimen is not widely used. There is limited data on the real-world efficacy and safety.

Modified pulley maneuver to guide surgical plane in minimally invasive liver resection.

Introduction: Achieving an adequate surgical plane through optimal traction is crucial for liver parenchymal transection in minimally invasive liver surgery (MILS). MILS is more technically demanding than open liver surgery because of limited instrument mobility and the inability to use the surgeon's hand, potentially leading to iatrogenic injuries. The Pulley maneuver using barbed sutures has been used for laparoscopic hepatectomy; however, the sutures are single-use and may pass through the liver parenchyma, making it uneconomical and inflexible.

Novel ERBB2 Variant Potentially Associated with Resistance against Anti-HER2 Monoclonal Antibody-Based Therapy in ERBB2-Amplified Metastatic Colorectal Cancer.

Purpose: HER2-targeted therapies in ERBB2-amplified metastatic colorectal cancer (mCRC) are effective; however, a notable portion of patients do not respond to treatment, and secondary resistance occurs in most patients receiving these treatments. The purpose of this study was to investigate determinants of treatment efficacy and resistance in patients with ERBB2-amplified mCRC who received HER2-targeted therapy by analyzing multiomics data.

Experimental Design: We investigated genomic data from a nationwide large cancer genomic screening project, the SCRUM-Japan project.
