Antibody-drug conjugates (ADCs) and tyrosine kinase inhibitors (TKIs) are widely used for HER2-positive metastatic breast cancer, but their efficacy in the neoadjuvant setting remains under investigation. The MUKDEN 06 trial (NCT05426486), a multicentre, randomised, phase 2b study, compared ARX788 (anti-HER2 ADC) plus pyrotinib (TKI) with the standard neoadjuvant regimen of docetaxel, carboplatin, trastuzumab, and pertuzumab (TCbHP) in female patients with early or locally advanced HER2-positive breast cancer. The primary endpoint was the pathological complete response (pCR, ypT0/is, ypN0) rate, analyzed in the intention-to-treat population. pCR was achieved in 70.6% (48/68) of patients receiving ARX788 plus pyrotinib, compared to 51.5% (35/68) in the TCbHP group, with a significant absolute difference of 19.1% (95% CI, 2.7-34.6; p = 0.023). No treatment-related deaths occurred. The most common grade 3-4 adverse events were diarrhea and hepatic dysfunction in the ARX788 plus pyrotinib group, and fatigue, nausea and anorexia in the TCbHP group. Interstitial lung disease (ILD)/pneumonitis and ocular events were observed with ARX788 plus pyrotinib, indicating a distinct safety profile. These findings offer clinical insights into the potential of dual HER2-targeted blockade with an ADC and TKI as an optional neoadjuvant strategy for patients with early or locally advanced HER2-positive breast cancer.

Biliary tract cancer (BTC) has a poor prognosis with limited treatment options. This phase 2 trial randomized 80 patients with unresectable/metastatic BTC 1:1 to sintilimab, anlotinib, and gemcitabine/cisplatin (SAGC) or chemotherapy alone (GC). At 13.4-month median follow-up, SAGC significantly improved median progression-free survival (8.5 vs. 6.3 months; HR 0.48, 95% CI 0.22-0.64, p = 0.005) and objective response rate (51.4% vs. 29.4%), with higher grade 3/4 adverse events (75.0% vs. 43.6%). Post hoc analysis showed enhanced efficacy with anlotinib 8 mg versus 10 mg (ORR 54.5% vs. 38.8%). In AKT/YAP tumor models, low-dose anlotinib (3 mg/kg) combined with sintilimab improved vascular perfusion, T-cell cytotoxicity, and cytokine secretion compared to high-dose (6 mg/kg). These findings demonstrate improved efficacy and manageable toxicity with SAGC, particularly at the 8 mg anlotinib dose, suggesting low-dose regimens may optimize antitumor response while mitigating adverse effects.

Osimertinib is the standard first-line options for patients with advanced EGFR-mutated non-small cell lung cancer (NSCLC). Co-mutations in TP53 results in poor survival for patients. However, the studies on treatment options and clinical outcomes of patients with EGFR-TP53 co- mutation are limited. Patients with EGFR mutation-positive locally advanced or metastatic NSCLC carrying TP53 mutations were recruited from two institutions and randomly allocated into two groups, either receiving osimertinib plus chemotherapy (Osi + Chemo group) or osimertinib monotherapy (Osi group). The progression-free survival (PFS) was evaluated as the primary endpoint and the response was also assessed. Between January 2020 and August 2023, ninety-eight patients were enrolled with 47 and 51 patients receiving combination therapy and the monotherapy. After a median follow-up of 19.2 months, overall response rate (ORR) was 80.0% vs. 71.7% (p = 0.36), favoring Osi + Chemo group, as well as in disease control rate (DCR) (91.4% vs. 80.4%, p = 0.45). The median PFS in the Osi + Chemo group was 26.0 months versus 20.7 months in the Osi group, but there was no significant difference (p = 0.34). The subgroup analysis indicated that for patients with L858R mutation, Osi + Chemo therapy significantly prolonged the median PFS (not reached [NR] versus 17.1 months, p = 0.03), but showed no benefit in patients with 19Del (20.6 months versus NR, p = 0.31). Osimertinib plus chemotherapy has a tendency to increase ORR and prolong PFS in NSCLC with EGFR and TP53 co-mutations, particularly in patients with L858R mutation.

In ENGOT-cx11/GOG-3047/KEYNOTE-A18 (NCT04221945), pembrolizumab (vs placebo) + concurrent chemoradiotherapy (CCRT) followed by pembrolizumab (vs placebo) significantly improved progression-free survival and overall survival in participants with newly diagnosed, high-risk locally advanced cervical cancer (LACC). We report patient-reported outcomes (PROs) from the study.

Patients with advanced or recurrent endometrial cancer (EC) have poor prognosis despite treatment with combination chemotherapy. This study explored the preliminary efficacy of the potent oral tyrosine kinase inhibitor nintedanib (N), in addition to chemotherapy.

In urothelial carcinoma, prior studies have indicated that the basal/squamous molecular subtype and the presence of select DNA damage response (DDR) gene alterations are associated with improved benefit from cisplatin-based chemotherapy. We sought to evaluate these biomarkers in specimens from the phase III Cancer and Leukemia Group B (CALGB) 90601 trial.

Trastuzumab combined with chemotherapy is a standard treatment for human epidermal growth factor receptor 2 (HER2)-positive advanced breast cancer in later lines. Lapatinib and trastuzumab have also demonstrated efficacy. This study assessed the efficacy, toxicity, and quality of life (QoL) of trastuzumab plus lapatinib (with endocrine therapy for hormone receptor-positive cases) versus trastuzumab with physician-selected chemotherapy in patients previously treated with at least 2 anti-HER2 regimens.

DUO-E/GOG-3041/ENGOT-EN10 (NCT04269200) demonstrated statistically significant and clinically meaningful progression-free survival (PFS) improvement with durvalumab plus carboplatin/paclitaxel, followed by durvalumab with or without olaparib, vs. carboplatin/paclitaxel alone (intention-to-treat [ITT] population) in patients with newly diagnosed advanced or recurrent endometrial cancer. We evaluated efficacy and safety in the Japan subset of DUO-E.

This post-hoc analysis of the AtTEnd trial explored differences in the prognostic characteristics and in the efficacy of atezolizumab between Asians and non-Asians.

In the phase 3 KEYNOTE-826 study (NCT03635567), pembrolizumab plus chemotherapy with or without bevacizumab significantly improved progression-free survival (PFS) and overall survival (OS) in participants with persistent, recurrent, or metastatic cervical cancer. We report an exploratory analysis of outcomes for participants enrolled in East Asia based on the final analysis of KEYNOTE-826.

The phase 3 BELLINI primary endpoint was met, showing superior progression-free survival with venetoclax versus placebo plus bortezomib and dexamethasone in patients with relapsed or refractory multiple myeloma as assessed by an independent review committee. However, venetoclax showed increased early mortality. Here, we report the final overall survival analysis.

Mobile apps to support the delivery of cancer care are proliferating, often without adequate evidence. Lung Cancer App (LuCApp) is a mobile app developed by researchers, clinicians, and patients to promote real-time monitoring and management of symptoms in patients with lung cancer. We aimed to investigate the effect of LuCApp on health-related quality of life (HRQoL), anxiety and depression, and overall survival up to 24 weeks after pharmacological treatment start, as well as its impact on resource use.

In node-positive breast cancer patients undergoing neoadjuvant therapy (NAT), targeted axillary dissection (TAD) combining sentinel lymph node (SLN) biopsy and removal of a pretherapeutically marked metastatic node is increasingly used to adequately stage the axilla, thereby omitting axillary lymph node dissection (ALND). Reliable localization of the clipped node is critical, however no prospective randomized comparisons of available marking systems have been published.

In ARIEL3, rucaparib maintenance significantly improved progression-free survival (PFS; primary endpoint) and long-term follow-up (LTFU) outcomes (including PFS2: time to disease progression on subsequent therapy or death) versus placebo in patients with recurrent, platinum-sensitive ovarian cancer. Here we report the final analysis of overall survival (OS; key secondary endpoint), LTFU outcomes, and safety.

An exploratory analysis of past clinical trials was conducted to propose a predictive scoring system for the efficacy of mogamulizumab, an anti-CC chemokine receptor 4 (CCR4) antibody, based on easily measurable parameters. Factors affecting progression-free survival (PFS) were investigated using data from three clinical trials (NCT00920790, NCT01626664, and NCT01173887) and one clinical study (UMIN000013294) conducted in patients with relapsed/refractory (R/R) or untreated CCR4-positive aggressive adult T-cell leukemia-lymphoma (ATL) receiving mogamulizumab treatment. Twelve routinely measured clinical parameters and three calculated indices-lymphocyte-to-neutrophil count ratio, platelet-to-lymphocyte count ratio, and lymphocyte-to-monocyte count ratio (LMR)-were selected as variables. Univariate Cox proportional hazards analysis identified albumin level, disease type, lactate dehydrogenase (LDH), monocyte count, neutrophil count, and LMR as relevant factors in R/R ATL patients treated with mogamulizumab monotherapy (p < 0.05). A predictive model constructed from multivariate analysis results stratified the monotherapy group (n = 69) into three subgroups, with scores of 0 (n = 5), 1 (n = 25), and 2 (n = 39), based on LDH (0 for < 265 and 1 for ≥ 265) and LMR (0 for ≥ 3.571 and 1 for < 3.571). Median PFS values were 0.57, 0.46, and 0.07 years for scores 0, 1, and 2, respectively (log-rank test: p = 0.005 for score 0 vs. 2; p < 0.001 for score 1 vs. 2). The simple model combining LDH and LMR may predict PFS in patients with R/R aggressive ATL receiving mogamulizumab treatment. Since LDH and LMR are easily measurable in clinical practice, this model could help predict mogamulizumab efficacy and guide treatment decisions in this patient population.

Insulin-like growth factor-1 (IGF-1) may play a role in breast cancer (BC) development. Metformin was found to exert anti-cancer function in several studies, partly by interference with the IGF-1 signaling pathway and reducing its blood levels. Therefore, our study aimed primarily to find out how metformin affected both IGF-1 levels and clinical outcomes in metastatic breast cancer patients (MBC) and secondarily to identify the correlation between post-treatment IGF-1 decline rates and BC prognosis and metastasis.

This study aimed to compare the quality of mediastinal lymph node dissection (LND) during lobectomy for clinical stage I-II non-small cell lung cancer (NSCLC) between video-assisted thoracic surgery (VATS) and open thoracotomy, using data from the Japan Clinical Oncology Group (JCOG) 1413 phase 3, randomized, controlled trial.

The combination of FOLFOX/FOLFIRI with an EGFR-antibody (cetuximab/panitumumab) is a first-line standard for RAS wild-type metastatic colorectal cancer (mCRC). The OPTIMOX stop-and-go regimen, which reduces oxaliplatin-induced neuropathy, and fluorouracil/folinic acid (FU/FA) were standard maintenance-therapies in the pre-antibody era. Whether an EGFR-antibody adds value to the OPTIMOX strategy in the RAS wild-type setting remains unknown.

This research aimed to identify significant prognostic factors that interact with the treatment effect of capecitabine and oxaliplatin (CapeOX), based on individual patient data from the CLASSIC study (NCT00411229), which evaluated the efficacy of adjuvant chemotherapy for gastric cancer.

Endoscopic surveillance is the clinical standard for Barrett's oesophagus, but its effectiveness is inconsistent. We have developed a test comprising a pan-oesophageal cell collection device coupled with biomarkers to stratify patients into three risk groups. We aimed to prospectively evaluate the prespecified risk stratification tool to establish whether it can identify those at highest risk of dysplasia or cancer to prioritise the timing of endoscopy; and safely be used to follow up the low-risk group, thus sparing patients from unnecessary endoscopies.
